Charles Richter, Inventor of the Richter Magnitude Scale
Charles Richter, Inventor of the Richter Magnitude Scale Seismic waves are the vibrations from earthquakes that travel through the Earth; they are recorded on instruments called seismographs. Seismographs record a zig-zag trace that shows the varying amplitude of ground oscillations beneath the instrument. Sensitive seismographs, which greatly magnify these ground motions, can detect strong earthquakes from sources anywhere in the world. The time, locations, and magnitude of an earthquake can be determined from the data recorded by seismograph stations. The Richter magnitude scale was developed in 1935 by Charles F. Richter of the California Institute of Technology as a mathematical device to compare the size of earthquakes. The magnitude of an earthquake is determined from the logarithm of the amplitude of waves recorded by seismographs. Adjustments are included for the variation in the distance between the various seismographs and the epicenter of the earthquakes. On the Richter Scale, magnitude is expressed in whole numbers and decimal fractions. For example, a magnitude 5.3 might be computed for a moderate earthquake, and a strong earthquake might be rated as magnitude 6.3. Because of the logarithmic basis of the scale, each whole number increase in magnitude represents a tenfold increase in measured amplitude; as an estimate of energy, each whole number step in the magnitude scale corresponds to the release of about 31 times more energy than the amount associated with the preceding whole number value. At first, the Richter Scale could be applied only to the records from instruments of identical manufacture. Now, instruments are carefully calibrated with respect to each other. Thus, magnitude can be computed from the record of any calibrated seismograph. Earthquakes with magnitude of about 2.0 or less are usually called microearthquakes; they are not commonly felt by people and are generally recorded only on local seismographs. Events with magnitudes of about 4.5 or greater- there are several thousand such shocks annually- are strong enough to be recorded by sensitive seismographs all over the world. Great earthquakes, such as the 1964 Good Friday earthquake in Alaska, have magnitudes of 8.0 or higher. On average, one earthquake of such size occurs somewhere in the world each year. The Richter Scale has no upper limit. Recently, another scale called the moment magnitude scale has been devised for more precise study of great earthquakes. The Richter Scale is not used to express damage. An earthquake in a densely populated area which results in many deaths and considerable damage may have the same magnitude as a shock in a remote area that does nothing more than frighten the wildlife. Large-magnitude earthquakes that occur beneath the oceans may not even be felt by humans. NEIS Interview The following is a transcript of an NEIS interview with Charles Richter: How did you become interested in seismology?CHARLES RICHTER: It was really a happy accident. At Caltech, I was working on my Ph.D. in theoretical physics under Dr. Robert Millikan. One day he called me into his office and said that the Seismological Laboratory was looking for a physicist; this was not my line, but was I at all interested? I talked with Harry Wood who was in charge of the lab; and, as a result, I joined his staff in 1927. What were the origins of the instrumental magnitude scale?CHARLES RICHTER: When I joined Mr. Woods staff, I was mainly engaged in the routine work of measuring seismograms and locating earthquakes, so that a catalog could be set up of epicenters and times of occurrence. Incidentally, seismology owes a largely unacknowledged debt to the persistent efforts of Harry O. Wood for bringing about the seismological program in southern California. At the time, Mr. Wood was collaborating with Maxwell Alien on a historical review of earthquakes in California. We were recording on seven widely spaced stations, all with Wood-Anderson torsion seismographs. What modifications were involved in applying the scale to worldwide earthquakes?CHARLES RICHTER: Youre quite rightly pointing out that the original magnitude scale which I published in 1935 was set up only for southern California and for the particular types of seismographs in use there. Extending the scale to worldwide earthquakes and to recordings on other instruments was begun in 1936 in collaboration with Dr. Gutenberg. This involved using the reported amplitudes of surface waves with periods of about 20 seconds. Incidentally, the usual designation of the magnitude scale to my name does less than justice to the great part that Dr. Gutenberg played in extending the scale to apply to earthquakes in all parts of the world. Many people have the wrong impression that the Richter magnitude is based on a scale of 10.CHARLES RICHTER: I repeatedly have to correct this belief. In a sense, magnitude involves steps of 10 because every increase of one magnitude represents a tenfold amplification of the ground motion. But there is no scale of 10 in the sense of an upper limit as there is for intensity scales; indeed, Im glad to see the press now referring to the open-ended Richter scale. Magnitude numbers simply represent measurement from a seismograph record- logarithmic to be sure but with no implied ceiling. The highest magnitudes assigned so far to actual earthquakes are about 9, but that is a limitation in the Earth, not in the scale. There is another common misapprehension that the magnitude scale is itself some kind of instrument or apparatus. Visitors will frequently ask to see the scale. Theyre disconcerted by being referred to tables and charts that are used for applying the scale to readings taken from the seismograms. No doubt you are often asked about the difference between magnitude and intensity.CHARLES RICHTER: That also causes great confusion among the public. I like to use the analogy with radio transmissions. It applies in seismology because seismographs, or the receivers, record the waves of elastic disturbance, or radio waves, that are radiated from the earthquake source, or the broadcasting station. Magnitude can be compared to the power output in kilowatts of a broadcasting station. Local intensity on the Mercalli scale is then comparable to the signal strength on a receiver at a given locality; in effect, the quality of the signal. Intensity like signal strength will generally fall off with distance from the source, although it also depends on the local conditions and the pathway from the source to the point. There has been interest recently in reassessing what is meant by the size of an earthquake.CHARLES RICHTER: Refining is inevitable in science when you have made measurements of a phenomenon for a long period of time. Our original intent was to define magnitude strictly in terms of instrumental observations. If one introduces the concept of energy of an earthquake then that is a theoretically derived quantity. If the assumptions used in calculating energy are changed, then this seriously affects the final result, even though the same body of data might be used. So we tried to keep the interpretation of the size of the earthquake as closely tied to the actual instrument observations involved as possible. What emerged, of course, was that the magnitude scale presupposed that all earthquakes were alike except for a constant scaling factor. And this proved to be closer to the truth than we expected.

What Teachers Need to Know About Being a Club Sponsor
What Teachers Need to Know About Being a Club Sponsor Almost every teacher will be approached at some point and asked to sponsor a club. They might be asked by an administrator, their fellow teachers, or the students themselves. Being a club sponsor is full of many rewards. However, before you jump in feet first you should consider exactly what it is you are getting involved in. Student Club Sponsorship Takes Time While this might seem obvious, it is important that you understand the time commitment involved in sponsoring a student club. First, realize that all clubs are not equal. Each club will require work but some require more work than others. For example, a student club devoted to surfing or chess will probably not take as much time as a service club, especially one with a large number of members. Service clubs such as Key Club or the National Honor Society require numerous service projects that are labor intensive on the part of the sponsor. Any extracurricular club activities will require adult coordination and supervision. In order to gauge how much time you will need to set aside for club sponsorship, talk with teachers who have previously sponsored that particular club. If possible, look at the club by-laws and previous year student events. If you feel that the club is too much to take on due to the time commitment you can either choose to decline the invitation or find a co-sponsor for the club. However, if you do choose a co-sponsor, make sure you pick someone you feel will take on 50% of the time commitment. Dealing With Students Within the Club A student club will typically hold an election in which students are chosen to be the president, vice-president, treasurer, and secretary of the club. You should understand that these are the students with whom you will be working the closest. In fact, if the right individuals are chosen for the job, your role will be much simpler. Realize, however, that there might be students involved in the club who do not participate fully. This can lead to problems. For example, if your club has organized an activity and if the one student who is required to bring the drinks does not show, then you will probably be making a quick run to the store and spending your own money to buy the drinks. Money and Dues Sponsoring a student club also means that you will most probably be dealing with dues and monies collected from the students. Before you even begin the process, make sure that you have not only built up a positive relationship with the schools bookkeeper but also that you understand the exact process for collecting money. While there will be a treasurer, as the adult you will be responsible for making sure that the money is treated responsibly. In the end, you will be held responsible if money is missing. School Club Sponsorship Can Be Fun This article was not meant to scare you away from being a club sponsor. Instead, realize that there are many rewards for those willing to put in the time. You will build a stronger relationship with students within the club. You will also learn a lot about the students, more than you can possibly learn while in the classroom setting. Finally, you will have the reward of helping enrich students lives through extracurricular activities.

New Humanism in Architecture Research Proposal Example | Topics and Well Written Essays - 1250 words
New Humanism in Architecture - Research Proposal Example à Working with Nature to create architectural statements is possible as shown by the students at the University of Maryland. The students won the second place at the Solar Decathlon in 2007 with their ââ¬Å"Leaf House,â⬠a home with a roofline resembling a leaf and an indoor waterfall that provides a liquid desiccant. (DCraig, 2007) In New Paltz, Net-zero home (Schoenfeld, 2011) BOLDER Architecture designed the first zero-net energy development using ââ¬Å"photovoltaic-solar panels and geothermal heating and cooling, combined with insulated concrete form walls, triple pane glass, and heat recovery ventilatorsâ⬠(Toder, 2006). Unlike the Leaf House which was designed specifically for a contest, these homes in New Paltz are already occupied. Contrary to the insights of the Manifesto: Towards A New Humanism In Architecture, BOLDER Architecture has ââ¬Å"dared to actâ⬠(Toder, 2006) and as a consequence has created homes of the future. At present, there exist visually -pleasing structures which are also eco-friendly. These buildings and homes are recognized by both public and private award-giving organizations for their beauty and their energy-saving features. This only proves that architects can remain true to their calling of creating aesthetically appealing buildings and make these beneficial to the society and environment. Toward a Human Architecture: A Sociologistââ¬â¢s View of the Profession Through time, buildings have been a part of society because architects consult with men to come up with structures that often makeââ¬âmust makeââ¬âa statement. At times, the resulting structures turn out to be contrary to what was envisioned by the client. As architect Bob Borson has written, he had been fired from a project ââ¬Å"for not listeningâ⬠. (Borson, 2010) This kind of dilemma is exactly why sociologist Herbert Gans (1993) suggests that architects should start building with their clientââ¬â¢s needs in mind. Indeed, society appreciates a building with a unique architectural design. Not only does it make the place visually appealing but it also helps establish the architect in the field. Will Alsop knows that well, struggling to create himself a name which is now synonymous to magnificent structures in Peckham Library (Greer, 2007) the United Kingdom. In his works, Alsop lets his imagination run even if the outcome is not something that the public may want. (Worsley, 2002) This makes for buildings that have a high aesthetic value but may not be functional and comfortable for the people using these structures. Another architect whose works aim to be visually appealing is Odile Decq. Her take on the Shanghai Information Center is indeed a striking mixture of straight lines and triangles. Looking at the structure though makes one wonder if each space inside serves a purpose and can be utilized. Shanghai Info. Center (Decq, 2011) It has been said that an architect, like a painter or a sculptor, creates beau ty.

Sara Lee Corporation Case Study Example | Topics and Well Written Essays - 2000 words
Sara Lee Corporation - Case Study Example The strategy was also developed so as to allow the company to primarily focus its vital resources on the currently more profitable household products, beverages and foods industries with the aim of strengthening the companyââ¬â¢s financial position. By the year 2007, Sara Leeââ¬â¢s Operating Excellence was seen not to be progressing as expected and hence the management introduced a new policy to help optimize the companyââ¬â¢s overall productivity by initiating Project Accelerate (Thompson, et al., 243-256). Issues and Problems The seven units that Sara Lee divested generally included European nuts and snacks, direct sales, European and U.S. meats, U.S. retail coffee, European apparel, European Rice and Sara Lee branded apparel. By exiting from the operations of these eight businesses that the company perceived as being mainly nonstrategic, the company essentially followed a strategy that allowed it to increase its share of the corporate profits, due to the fact that most of the business units that the company retrenched were deemed as being unprofitable. By the year 2006, about five of these business units were seen to have negative net profit margins as well as negative operating margins. The European nuts and snacks, and the direct selling unit were essentially the only units that were generally profitable. These two units were experiencing declining operating margins and revenues apart from the increase in margins that they experienced in 2006 (Thompson, et al., 254). The decision to divest the companyââ¬â¢s snack operations can be deemed as having been the correct one as the division was only able to produce net profits of about $3 million an amount which would not have resulted in considerably increasing the wealth of the companyââ¬â¢s shareholders. In the deal to sell the unit, the company managed to receive about $70 million after taxes, this was a positive development as it was about 22 times the current net profit (Thompson, et al., 248 ). The decision to spin off Hanesbrands can essentially be seen to have resulted in seriously crippling Hanesbrands as it incurred a huge long-term debt that can potentially seriously affect its ability to turn considerable profits in the future (Thompson, et al., 248-249). The decision to sell its direct sales units can generally be regarded as having been a bad decision as the unit was drawing a profit margin of about 27% with an estimated income of about $54 million (Thompson, et al., 247). The direct sales division also served to expose Sara Lee corporation to other markets a factor which could have served to allow the company to potentially find new markets for some of its other products. However, by selling the unit, Sara Lee managed to receive a net gain of about 4 times of the unitââ¬â¢s current profits. An Analysis of Sara Lee Corporationââ¬â¢s Macro-Environment Pestle Analysis of Sara Lee Corporation There are various key factors that can be seen to be affecting Sara Leeââ¬â¢s Corporationââ¬â¢s external environment. Some of these factors include: Political Factors: Some of the main political factors affecting Sara Lee include the various political issues surrounding the companyââ¬â¢s strategy of divesting its business operations. Economic Factors: The impact of the recent global recession was seen to have an effect on a number of industries across the world and was seen to also affect the operations of Sara Lee corporation. The companyââ¬â¢s bimbo brand of fresh bread that was seen to be the market leader in packaged bread that was sold in Spain with an impressive market share of about 37 percent and was subsequently ranked as being the second-best-selling packaged bread in Spain happened to be rather severely affected by

United States Declaration of Independence Essay Example for Free
United States Declaration of Independence Essay The enlightenment era arose in the modern cultural ideology of the 18th century, as ideas among philosophers had a widespread effect among the society. The age of enlightenment, in western society, projected the rejection of traditional Christianity, western philosophy, intellectual advances, scientific, and cultural life, government legitimacy and authority. Upon the enlightenment period multiple philosophers emerged, the individuals arose to leading figures using reason to understand all aspects of human life. The motivations for the enlightenment came primarily from the Englishmen, John Locke. John Locke was a philosophical influence in both political theory and theoretical philosophy, which was embraced among the era of 1789-1914 and the concept of equal rights among men. John Lockeââ¬â¢s writings influenced the works of multiple diplomats concerning liberty and the social contract between society and the government. Lockeââ¬â¢s ideology of man and power was the base for the concept of separation of powers. As one of the enlightenment thinkers, John Locke wrote the Two Treatises of Government influencing the framework of his ideal vision of the nature of man and his freedom, stating that all men exist in ââ¬Å"a state of perfect freedomâ⬠as ââ¬Å"every man being, has been showed, naturally free. â⬠(Primary Sources, 156) His theories involved the money value within trading systems, education ideals, the blank mind shaped by surroundings, and the framework for the American Revolution. Lockeââ¬â¢s ideas were taken and embraced as his ideas ââ¬Å"seemed to offer the hope of a brave new worldâ⬠built on reason. â⬠(Spielvogel 516) The enlightenment was an era of intellectual and social growth as people began to challenge and view the world changed. During the era, society began to believe all men are free people, a concept enforced by John Lockeââ¬â¢s ideologies. John Locke believed every person was born with tabula rasa, blank mind, arguing in Essay on Human Understanding that men and women, were products of their environment, and implied that humans were molded by their surroundings. With the theory of the blank mind, John Locke presented with reason and logic that men and women could improve themselves by improving the surroundings. As John Locke rejected ââ¬Å"authority and theoryâ⬠¦ [by] showing knowledge derives from sensory perception and experienceâ⬠¦Ã¢â¬ he impacted western philosophy and the understanding of knowledge. (Primary sources 212) Lockeââ¬â¢s idea implied the restructure of society as by changing the environment, men would be properly influenced, and a new society created. The idea of a perfect new society was seen among the creation of the utopian community by Robert Owen. The idea of men being able to be shaped by the community is seen among Owenââ¬â¢s work to set up the model community. Through his works in A New View in Society Owen shows how the communitarian project achieved ââ¬Å"moral improvement with commercial successâ⬠with the help of an orderly system to manufacture, and ââ¬Å"inculcating the moral virtues of cleanliness, order thrift, and sobriety. â⬠(Primary Sources 320) Owen was successful in creating the modeled community, with the idea of tabula rasa, and creating a cooperative self-contained community. The enlightenment employed the right of equality among all men. John Locke advocated natural rights of man, mainly life, liberty, and property. His avocation for men equality included the validity of governments powers should rely on consent from the citizens. The pursuit of representation from government led to the democracy in the Americaââ¬â¢s as they created the separation of powers. Locke supported the overthrow of absolute power, as he rejects the concept of royal superiority in his Second Treatise of Government. His belief in mutual consent from the people to the government is the basis of the social contract, showing how manââ¬â¢s ââ¬Å"perfect freedomâ⬠¦and liberty [should give man] is able to instruct him in that law he is to govern himself. â⬠(Primary Sources, 151) Lockeââ¬â¢s political ideology included overthrowing government if citizens felt their rights were taken away, citizens had the duty to revolt against the tyrant. This ideology is embraced during the French Revolution as ââ¬Å"before the revolution, French society was grounded in the inequality of rights,â⬠among the citizens. (Spielvogel578) The French were divided into classes, having no voice among the three estates, leading to the national assembly. The national assembly, influenced by John Lockeââ¬â¢s ideology of rejecting royal reign superiority, created the Declaration of the Rights of Man and of the Citizen. Lockeââ¬â¢s argument of revolution against tyranny was accepted to bring reasonable rule to the nation and citizens. The same liberalist view of overthrowing of ruler is seen during the napoleon rule. Benjamin Constant published The Principles of Politics advocating for the regulations of the generals will of the individuals liberty, ââ¬Å"distinguishing between sovereignty, authority, and individual freedom,â⬠right before Napoleonââ¬â¢s final defeat. (Primary Sources 342) Many of John Lockeââ¬â¢s ideas were input into the Declaration of Independence, as his primary words ââ¬Å"life, libertyâ⬠and instead of property, the pursuit of happiness, are the basis of the American Constitution and Declaration of Independence. Lockeââ¬â¢s arguments concerning liberty influenced the works of James Madison, Alexander Hamilton, Thomas Jefferson, as his Second Treatise is imitated in the Declaration of Independence. When the founding fathers adopted the resolution for the nationââ¬â¢s independence, with the restating of john Lockeââ¬â¢s theory of revolution, they opened the door to the war of American Independence. As well as Lockeââ¬â¢s separation of powers was framework for the American democracy created after the independence from Britain and the belief of revolting is an obligation in the certain circumstances. With the fear of a concentrated power the founding fathers of America secured the rights life, liberty, and pursuit of happiness, to which the government institutes the rights and derive their powers with the consent of the men. When creating the independence the people laid the foundation of separation of powers in which each branch is checked and has no overruling power among the rest of the government. With the influence of John Lockeââ¬â¢s political ideologies, the American colonies, after the American Revolution, ââ¬Å"proved to many Europeans that the liberal political ideas of the Enlightenment were not a vapid utterances of intellectuals. The rights of man, ideas of liberty, and equality, popular sovereignty, separation of powers, and freedom of religionâ⬠¦were not only utopian ideals. â⬠(Spielvogel 578) The Americans had taken John Lockeââ¬â¢s theories and made the concept of liberty reality. Consequently the American Revolution had an impact on the French revolution with the returning soldiers the influence of the American Declaration of Independence was seen among the Declaration of the Rights of Man and of the Citizen. The French revolution was more violent than the American, but it set the political movement for the modern political world. John Locke political theories were focused on the protection of the human rights, responsibility of the government, clarifying the concept between state and man. Locke insisted on the limits towards political authorities, and believed government should be selected, not born into, by the will of the majority. This set the fundamental declaration of the French revolution. John Locke an advocate for religious tolerance, wrote the Letters Concerning Toleration, conveying reasoning for religious tolerance after the European wars of religion. Within the Letters Concerning Toleration, Locke debates for the people to understand the relationship within religion and government, and how people should know the separation of the two. Separation of Church and State was created by Thomas Jefferson, who was greatly influenced by Lockeââ¬â¢s writings, as Locke feared that without distinction between the two, the personal beliefs will mislead the commonwealth. His advocacy for religious also influenced the freedom of religion among the Americans in the Bill of Rights, as man has the right to practice or to not practice any religion. Known for his political theories, notions on natural rights and separation of powers, John Locke also held beliefs regarding the education. Originally a letter to a friend regarding his sonââ¬â¢s education, Some Thoughts Concerning Education, Locke suggested the best way to educate the child. His theory for education was based on the argument of human mind at birth is a tabula rasa therefore a child was able to be molded with virtues. ââ¬Å"He attentively considers the state of a childâ⬠¦ [are] stored with plenty of ideas, that are to be the matter of his future knowledge. â⬠(Primary Sources 214) Lockeââ¬â¢s ideas on education involved learning from experience, and influenced the concern of public education during the 1789-1914 era. His theories and ideas on education would motivate the public school system in Britain. John Lockeââ¬â¢s emphasis on education was seen in Robert Owenââ¬â¢s utopian ââ¬Å"model community. â⬠In Owenââ¬â¢s New View of Society he set his influence by Lockeââ¬â¢s education, by stating that education was not only good for business in his utopian society, but for the nation as a whole. The influence of how the importance of education was enforced by Lockeââ¬â¢s ideologies of the ability to shape the minds of the children to better the nation. John Locke publicized a theory of money and property in his Two Treatises on Government. Lockeââ¬â¢s theory believes the natural right of estate. His belief in money describes that money fulfills the need for a constant measure of value and worth in a trading system. Locke argued for an economic system which could exist in the states and protection of property by the society. His ideal on a trading system influenced the merchandized 18th century industry. The eighteenth century was formed based on the growth of commercial led by John Lockeââ¬â¢s economic system theory on trade. The ââ¬Å"growth of commercial capitalism led to integrated markets, joint-stock trading companies, banking and stock exchange facilities,â⬠which shaped the nations view on money. (Spielvogel 564) As the eighteenth century flourished, Locke stated gold, silver, gems never rot, and therefore with the consent of mankind they become of monetary value and are open for trading value. With his theories of trading and money, John Locke can be seen as the creator of the bourgeois capitalism. The trading system was influenced by John Locke and embraced in the European trading which gave growth of cities, prosperity within the cities, the industrialization, and the manufacturing business. The Enlightenment was period of time with great thinkers bringing radical changes to society and the world. John Locke, known for Father of Liberalism and the enlightenment thinker, had a great impact among philosophers. John Locke was advocating the freedom of the individual, systems of government, nonviolent modification of political, social, or economic institutions, and governmental guarantees of individual rights and civil liberties. Lockeââ¬â¢s enlightenment ideas were employed during the long 19th century. ââ¬Å"Lockeââ¬â¢s treatises inspired the political theories of the Enlightenment. â⬠(Primary sources 148) His philosophical ideals influenced many other philosophers, utopian societies, the upheavals against government, the protection of rights, the education system in Britain, and the basis for modern government.

Television and Media - America Needs TV Advertising :: Argumentative Persuasive Topics
America Needs TV Advertising Television would not be in the place it is today had it not been for commercials. Commercials not only provide a much needed break from the shows we watch, but also gives paying advertisers a chance to promote their products. With a large audience watching, businesses spend untold amounts of money to make sure their commercials are the best. The worst nightmare however for an company is for a couch potato to not look at their commercial, but instead change the channel. To remedy this advertisers strive to capture the attention of the audience as soon as possible. If the audience does not like what they see within the first ten to fifteen seconds then most likely they will change the channel. Miller Lite "Miller Time" commercials counteract this ingeniously. The distinctive opening music create a light and humorous mood and instills curiosity in the viewer about what will happen next. The offbeat and sometimes absurd characters give the audience a well deserved laugh. For example, a man obviously dressed up as a beaver gnaws a log cabin, and then everything wooden and goes after a man holding a Miller Lite beer can. One does not think too much about the ad (for if one did he would wonder why do these commercials sometimes have nothing to do with their product?) but instead gets caught up in the comedy. The humor in these ads immediately captures their audience immediately and leaves them with a smile on their faces. Feeling good is also what makes Burger King's commercials so attractive. The typical Burger King commercial features 60's or 70's dance music accompanied by various shots of burgers. The music, if the audience likes it, pulls them in, watching it sometimes simply for the music. That is most often the case with my brother who "shakes his groove thing" to the music while not fully realizing that the thing which motivates him is simply inanimate and unhealthy food. The implicit message the advertisers send it seems, is that if you are dancing in your seat at home, how more will you love them in person? Attraction comes in the form of nostalgia, a more subtle and hence less used part of advertising. Chili's commercials with singing tamales on an open frontier uses music like the Burger King ads but creates a mood of nostalgia rather than one of excitement.

Quality Of Life Thalassemia Patients Health And Social Care Essay
Thalassemia is familial upset of blood characterized by anaemia. It is the most common individual cistron upset in the universe with bulk of new instances in the development states. Thalassemia is a chronic disease in which patients can non do plenty good quality haemoglobin to prolong life. Therefore these ruddy cells break down prematurely ensuing in terrible anaemia. Epidemiology It is prevailing in the antecedently malaria endemic zones all over the universe. The planetary thalassaemia bearer frequence is about 5 % . It is widely prevailing in Bangladesh with bearer frequence of 7 % among which 4 % HbE bearers and 3 % beta thalassaemia bearers. It is estimated that 7000 new babes born with thalassaemia each twelvemonth. Thalassemia patients undergo womb-to-tomb blood transfusion and Fe chelation. WHO defines quality of life as ââ¬Å" an person ââ¬Ës perceptual experience of their place in life in the context of the civilization and value systems in which they live and in relation to their ends, outlooks, criterions and concerns. It is a wide ranging construct affected in a complex manner by the individual ââ¬Ës physical wellness, psychological province, personal beliefs, societal relationships and their relationship to salient characteristics of their environment. ââ¬Å" 1RationaleHemoglobin upsets are an emerging planetary wellness job. The quality of life surveies in developed states revealed important lessening in QOL due to hard and long term intervention. Though the disease is rather common in Bangladesh, there was no survey conducted on health-related quality of life ( HRQOL ) in Bangladesh and hazard indexs associated with it. There is scarceness of published research in thalassaemia in Bangladesh. A PubMed hunt with keyword ââ¬ËThalassemia Bangladesh ââ¬Ë returned merely 13 consequences. Most diseases have a major impact on the afflicted single above and beyond mortality. Diseases that may non be deadly may be associated with considerable agony and disablement. For this ground, it is besides of import to see the impact of a disease as measured by its consequence on a individual ââ¬Ës quality of life, even though such step are non, in fact, steps of disease happening. For illustration, it is possible to analyze the extent to which patients with thalassemia rheniums compromised by the unwellness in transporting out activities of day-to-day life. Although considerable contention exists about which quality of life steps are most appropriate and valid there is general understanding that such steps can be reasonability used to be after short-run intervention plan for groups of patient. Such patients can be evaluated over a period of months to find the consequence of the intervention on their ego reported quality of life. Quality of life steps have besides been used for set uping precedences for scarce wellness attention resources. Although prioritization of wellness attention resources is frequently chiefly based on mortality informations, because many diseases are chronic and non life threatening, quality of life must besides be taken into history for this intent. Patients may put different weights on different quality of life steps depending on cultural background, instruction, and for illustration, spiritual values. As a consequence mensurating quality of life and developing valid indices that are utile for obtaining comparative informations in different patients and in different populations remain a major challenge. 2Conceptual ModelResearch QuestionWhat is the wellness related quality of life among the thalassaemia patients in the selected centres?

Each standard was scored 0-4 and amount of all standards used as the concluding mark.Review of Related LiteratureInternational PerspectiveIt is estimated that more than 300,000 kids are born with familial disease of haemoglobin each twelvemonth among which about 80 % born in low to income countries.3Regional PositionNational PerspectiveQOL A survey of hurting in the thalassaemia patient used SF-36v2 wellness study for adult/adolescent and kids were used PF-28 child wellness questionnaire.4 Iron Chelation Therapy ConformityPainThe progresss in the intervention of thalassaemia have resulted in increased life anticipation 5. The drawn-out life spans have exposed antecedently unidentified issues like bodily hurting. A survey conducted in the Thalassemia Clinical Research Network ( TRCN ) among 265 adults/adolescent and 103 kids with thalassemia 69 % of adult/adolescent reported bodily hurting with at least 28 % reported at least moderate hurting. Parent reported hurting in 56 % of kids while merely 11 % reported pain reasonably frequently. Though there was no difference in the hurting in kids with thalassaemia compared with the general population, hurting increased significantly with age. The survey besides showed that increased hurting is associated with lessening in quality of life and increased anxiousness and depression. 4 : Methodology This survey was done to happen out the wellness related quality of life of the thalassaemia patient in the selected centres in Dhaka metropolis and hazard indexs associated with it. The undermentioned methodological analysis was followed to carry on the survey.Study DesignA cross-sectional survey was designed to measure the HRQOL and associated hazard indexs. Figure 1: Conventional diagram of a cross-sectional surveyStudy PeriodThe entire survey period accounted 6 months from January 2010 to June 2010. During this period a scope of activity was undertaken get downing from title choice, protocol readying, protocol presentation, informations aggregation, informations cleansing, information analysis, study composing and printing. The clip allocated for informations aggregation by class coordinator was from 18 April 2010 to 7 May 2010. The elaborate work agenda is appended in AnnexureA -A 1.Study LocationThis survey was done on thalassaemia patients came at 3 centres in the Dhaka metropolis viz. ASHA -Thalassemia Center, Bangladesh Thalassemia Society and Thalassemia Hospital and Red Crescent Blood Center. Dhaka Shishu Hospital Thalassemia Center was planned as one of the sites in the initial protocol, but the establishment declined the research worker for informations aggregation. Therefore it was replaced with Red Crescent Blood Center with permission from research usher.Study PopulationThe survey population included all the patients coming to the survey location for outpatient audience and blood transfusion.Study SampleSampling Technique and Sample SizeA convenient sampling was done. All available instances within the informations aggregation period were included in the survey. Overall 120 instances were included in the survey.Calculation of Sample SizeEligibility CriteriaInclusion StandardsExclusion StandardsDevelopment of Research InstrumentA pretested semi structured Bangla questionnaire and checklist was used for informations aggregation. The variables were identified harmonizing to the specific aims and taking the of import variables into consideration which reveled in the literature reappraisal. Then appropriate graduated tables of measuring for these variables were identified and English questionnaire was drafted. After necessary rectification and tuning the English questionnaire was translated into Bangla. Th e questionnaire was so reviewed by research usher and co-workers of the research worker. The PedsQL Core scales 6-11 by James W. Varni was used for appraisal of quality of life with due permission from the writer. The tool consists of 4 ( four ) graduated tables for different age group i.e. Young grownup ( 18-25 ) , adolescent ( 13-18 ) , kid ( 8-12 ) , immature kid ( 5-7 ) . The interlingual rendition of the instrument was carried out harmonizing to the lingual guideline sent by the writer. The purpose was to develop a questionnaire which is conceptually tantamount to the original version, every bit good as clear and easy to understand. The interlingual rendition procedure consisted of three stairss ââ¬â Forward Translation Backward Translation Patient Testing In each measure a interlingual rendition study was prepared and sent to writer. For interlingual rendition of the PedsQL to Bangla, the research worker appointed two transcribers viz. Dr. Jenny Roslin D'costa and Dr. Tareq Salahuddin and himself acted as the undertaking director for the interlingual rendition procedure as stipulated in the lingual proof guideline. Each the transcriber was given the 4 ( Young grownup, adolescent, kid, immature kid ) original PedsQL graduated tables for different age group along with the lingual proof guideline. They were asked to interpret independently. After completion of the interlingual rendition a meeting was arranged on 16.04.2010 for rapprochement of the interlingual renditions. The undertaking director went through all 4 graduated tables one by one. There was no major dissension among the transcribers. They agreed to alter some of the words with equivalent word and rephrased some of the instructions and inquiries. Both the transcriber translated ââ¬Å" walk more than one block â⬠literally. The undertaking director pointed that actual interlingual rendition of western block will transport no significance in Bangla and among the mark population. Therefore he suggested it to be replaced with Bangla equivalent. He quoted Wikipedia mention below to explicate the significance of block. hypertext transfer protocol: //en.wikipedia.org/wiki/City_block ââ¬Å" Since the spacing of streets in grid programs varies so widely among metropoliss, or even within metropoliss, it is hard to generalise about the size of a metropolis block. However, as mention points, the standard block in Manhattan is about 264 by 900 pess ( 80 m A- 270 m ) ; and in some U.S. metropoliss criterion blocks are every bit broad as 660 pess ( 200 m ) . The blocks in cardinal Melbourne, Australia, are 660 by 330 pess ( 200 m A- 100 m ) , formed by dividing the square blocks in an original grid with a narrow street down the center. â⬠The transcriber discussed the issue and replaced block with ââ¬Å" walking more than 100 paces â⬠which is frequently used in Bangla to intend ââ¬Å" walk a short distance â⬠. After alteration of all four graduated tables ( Young grownup, adolescent, kid, immature kid ) version -1 of each paperss was prepared. Dr. Md. Rajib Hossain was appointed for the backward interlingual rendition of Bangla VersionA aÃâ ââ¬ËA 1 of the PedsQL graduated tables ( Young grownup, adolescent, kid, immature kid ) and research worker himself acted as the undertaking director. He was besides given the lingual proof guideline and asked non to entree the original graduated tables from cyberspace. After completion of the interlingual rendition a meeting was arranged on 17.04.2010 to compare his interlingual rendition with the original graduated tables. The consequence of the treatment in the meeting is documented in the undermentioned subdivision. The rubric contrary translated as ââ¬Å" list â⬠alternatively of ââ¬Å" stock list â⬠. This is due to non holding a similar word Bangla word. The closest interlingual rendition was synonymous to ââ¬Å" name â⬠and Dr. Hossain accepted it. In the Young Adult Report, Teen Report and Child Report ââ¬Å" walking more than one block â⬠, which was changed to ââ¬Å" walking more than 100 paces â⬠in forward interlingual rendition due to cultural differences was rearward translated same. Dr. Hossain besides agreed on the alterations made. The point 8 ââ¬Å" I have low energy â⬠was reverse translated as ââ¬Å" I feel weak â⬠. Therefore the interlingual rendition in version 1 was updated in version 2 which literally translates to ââ¬Å" I have low energy â⬠. In the emotion subdivision, point 4 ââ¬Å" I worry what will go on to me â⬠translated back as ââ¬Å" I get dying about my hereafter â⬠but it was decided to maintain the current Bangla interlingual rendition. In ââ¬Å" how I get along with others â⬠point 5, there is non actual interlingual rendition of ââ¬Å" equal â⬠hence the contrary interlingual rendition was ââ¬Å" others of my age â⬠which was acceptabl e. The other differences were considered as normal lexical fluctuations. In Young Child Report, ââ¬Å" a batch of job â⬠in the direction subdivision was back translated ââ¬Å" large job â⬠. In the reply options ââ¬Å" a batch â⬠was translated as ââ¬Å" many times â⬠. The difference was due to weak backward interlingual rendition. ââ¬Å" Functioning â⬠in the subdivision rubrics had no actual Bangla word, which was reflected in each of the subdivision rubric. The difference was acceptable. In the first subdivision ââ¬Å" Physical operation â⬠, foremost 6 points was translated as interrogative get downing with ââ¬Å" Do you â⬠. Therefore sentence building was altered to repair it. The other differences in all the graduated tables were considered normal lexical difference transporting the same significance of the original graduated table. The alterations were incorporated in version-1 of the translated graduated table and the version 2 is produced. In the patient proving measure, the research worker found that in the Likert graduated table ( 0-4 ) , patients did non understand the difference of ââ¬Å" frequently â⬠and ââ¬Å" about ever â⬠clearly. Therefore he suggested interlingual rendition of these two points to be modified which retranslate as ââ¬Å" frequently â⬠and ââ¬Å" ever â⬠. However the writer of the tool expressed his concern that altering ââ¬Å" about ever â⬠to ââ¬Å" ever â⬠will cut down your responses at that terminal of the graduated table. He advised to return to ââ¬Å" about ever â⬠which will be helpful in comparing the research worker ââ¬Ës findings with other published informations on the PedsQL utilizing a one-sample t-test. The writer suggested utilizing cognitive questioning method to get the better of this issue. The survey questionnaire was besides pretested along with the PedsQL graduated tables. Entire 37 points were included in the concluding questionnaire after necessary all right tuning.Datas Collection PlanThe PedsQL Generic mark tool has 4 graduated tables for different age group of 5-7, 8-12, 13-18 and 18-25 old ages. The sale for 5-7 old ages is interviewer administered while remainders are designed to be self administered. However the research worker communicated the writer of the tool about the low literacy rate which may cut down the pertinence of the ego administered tool. The writer provided a Cognitive Interviewing Guideline, which was applied for questioning all the tools.Data Processing and Analysis PlanAfter aggregation, informations were checked exhaustively for consistence and completeness. Datas were cleaned and edited manually. Statistical Package for Social Science ( SPSS ) version 16.0 for Windowss was used to analyse the information. Descriptive statistics were compu ted for the demographic variables. Chi-square analysis was carried out to measure the important association of qualitative informations. Datas were presented by tabular arraies and graphs.Quality AssuranceStudy RestrictionsPurposive samplingEthical IssuesThe survey was done through aggregation of informations utilizing questionnaire and neither any intercession nor any invasive process was be undertaken. However, prior to induction of the survey ethical clearance was taken from NIPSOM ethical commission. Before induction of the interview a brief debut on the purpose and aim of the survey was presented to the respondents. They were informed about their full right to take part or decline to take part in the survey. The research worker besides assured the respondents that there was no invasive process included in the survey and all the findings of the survey will be used to steer the service suppliers and policy shapers for the betterment of thalassaemia intervention. A complete confid ence was given to them that all information provided by them will be kept confidential and their names or anything which can place them will non be published or exposed anyplace. Their engagement and part will be acknowledged with due regard. After completion of these processs the interview was started with their due permission. : Consequences This cross sectional survey was conducted among 108 thalassaemia patients in three thalassaemia intervention centre in Dhaka metropolis. The information was analyzed utilizing appropriate descriptive and illative statistical processs and presented in this chapter utilizing tabular arraies and graphs, harmonizing to specific aims where applicable. The determination is organized under the undermentioned subdivisions4.1 Socio-demographic features of the respondents4.2Socio-demographic features of the respondentsData was collected on socio-demographic position of the respondents which is shown in the tabular array xx.xx.Age of the respondentsThe age of the respondent was usually distributed ( One sample Kolmogorov Smirnov Test, P =0.28 ) with average 13.28 old ages and standard divergence Aà ±5.19 old ages.

My Secret: Pacific Rose
When I think about art I see Picasso. I see faces, colors, things that should never be together are now one, a happy one: collages, statues, weird figures everywhere. Art is an adventure through expression, style, and creativity. When I say adventure Iââ¬â¢m speaking of a safari mixed with a survival of the fittest, spitting out only greatness and uniqueness. In Charlotte, North Carolinaââ¬â¢s Mint Museum there were many that attempted this adventure but one in particular who made it through was Jon Kuhn; his adventure was backed up by a breathtaking piece called Pacific Rose. Jon Kuhnââ¬â¢s background makes him seem as if he is a world renowned artist. Yet he is a very underrated artist with an array of accomplishments. Kuhnââ¬â¢s specialty is glass work but unlike other artists who use molten and blown glass, Kuhn uses cold glass that is cut, polished, and fused into many shapes from the outside in (Kuhn). This unique style of work has lead Kuhn to be featured in over 40 international museums, and a few public and private residences. One of his greatest accomplishments is having a few of his pieces claimed by the White Houseââ¬â¢s permanent collection. With such a broad resume Jon Kuhn should be a household name, yet Kuhn enjoys and would rather play the background underrated artist who ââ¬Å"brings light and joy to those who experience themâ⬠(Kuhn). When you see Jon Kuhnââ¬â¢s work you are sure to know itââ¬â¢s his. Kuhn likes to take a shape and make it where it absorbs light while reflecting a diamond like appearance (Kuhn). This is what captured my attention when it came to his amazing piece Pacific Rose. This piece was no bigger than roughly four feet and yet had such a loud, strong, engaging voice. When I first saw it I was amazed at how bright and colorful it was but the more I looked at it I saw something more, something deeper. Pacific Rose is four foot upside down, elongated, clear pyramid with two pyramids and a cube hanging freely within it. When one first looks at the shapes it looks like a bunch of small brick red, gray, black, and turquoise blocks put together to make the shapes. But the deeper you look into the figure you see that each small square has hundreds of layers. Also within the layers are scribbles and writing that take the piece to another level. I then walk around the piece to get a better view and I feel as if Iââ¬â¢ve been tricked. The solid shapes that I saw on one side are no longer solid. This is where the bright lights shining on the figure plays a huge role. In actuality the shapes look as if they have been annihilated, like an atomic bomb was dropped and the shapes are exploding. But the unique thing about these exploding figures is that all the while that they are exploding they somehow manage to keep their shape. This figure makes me want to get inside of the clear upside down pyramid and take a walk through the little figures within. This figure showed the exact path and journey Jon Kuhn took on his adventure through expression, style, and creativity. It not only showed this but also explained as to why he is featured in so many great places. His work is so amazing and extravagant that a part of me is happy that he is so underrated, for I would love to keep his beauties a secret and all to myself. But I know this is impossible for his work speaks so loud and with strength so strong that you must listen. It is only time before Jon Kuhn is being used as a household name. Jon Kuhn is now my new definition of art. Works Cited Page Kuhn, Jon. ââ¬Å"Artist Jon Kuhn.â⬠Kuhn Studio. N.p., 2002-2011. Web. 21 Dec 2011.

Conflict Resolutions essays
Conflict Resolutions essays Team conflict can be defined as a disagreement about ideas or interests. These conflicts arise because there is a diversity of different views within a team. These different views can get out of control if it is not managed appropriately. The conflicts can consist of disagreements, struggles, and arguments amongst team members (2001). Because each person is diverse from other team members, conflicts are inevitable (2001). Team management is a result of one member keeping the peace amongst other members of the team. To be an effective team manager, he/she needs to be aware of five possible situations that can cause conflicts in the work team environment. There are five key causes of team conflicts. These five conflicts consist of: personality conflicts, uneven distribution of work, lack of communication, incompatible learning or work styles, and conflicting schedules. Personality conflicts can be defined as a dispute amongst team members personal opinions about a given topic. These disputes are key elements to the natural process within a team. Without the differences in opinions and thought processes, a desirable outcome within a team may not be as effective as a team who possess the skills and knowledge of team dynamics. It has been known that diversity brings about change. Without change, processes are never given the chance to improve. Teams must be open to self improvement in order to be successful at what they are trying to get accomplished. Some of the pitfalls that can occur consist of: frustration, lack of cooperation, intimidation, and lost opportunity (Robinson, 2003). Frustration can occur when a situation has difficulty in agreement amongst team members. Frustration can also happen when someone is feeling like they are not given to opportunity to be heard. Lack of communication can result in lack of cooperation. Lack of co operation can also result in team members inability to accept change...

Free sample - Complex Congenital Heart Disease. translation missing
Complex Congenital Heart Disease. Complex Congenital Heart DiseaseComplex Congenital Heart Disease Congenital heart disease is a defectà or malformation in the structure of the heart or vessels that supply it with blood. This defect occurs as the fetus develops in the uterus and is therefore present at birth (Pampel, 2004). This defectà interferes with the normal flow of blood through the heart. Complex congenital heart disease requires immediate medical attention since it can be very fatal. Complex congenital heart disease can be attributed to both genetic and environmental factors. A pregnant woman who suffers rheumatic heart disease produces antibodies which act against the Ro and La auto antigens in the fetus (Pampel, 2004).à The part of the Ro antigen targeted by the antibodies from the mother is called p200 protein. The more the number of antibodies produced against this protein, the more the damage to the heart of the fetus. This antibody - antigen reaction causes the inflammation and subsequent calcification of the cardiac system of the fetus hence damaging the he art structure (Calnan, 1991). Researchers also have it that anti-seizure medication taken by a pregnant woman makes the fetus more vulnerable to congenital heart disease. Pregnant women who take lithium to treat depression, as well as those who have phenylketonuria (PKU) and do not strictly take the special diet prescribed to them predispose the fetus to the attack (Calnan, 1991). Women who contractà the Rubella virus and those who get vaccinated against the same stand higher chances of giving birth to children with CHD. Other studies indicate that this condition has autosomal-dominant inheritance meaning that mothers who have the condition stand about fifty percent chances of passing it to the child (Kaplan, 2002). A number of Chromosome abnormalities can also result to CHD. These include: Down syndrome, trisomy 18 and 13, turnerââ¬â¢s syndrome, cri du chat syndrome, wolf ââ¬â Hirsh horn syndromeà and Digeorge syndrome ( deletion 22q11). Genetic syndromes have also been shown to make one more vulnerable to the condition. These are: Marfan syndrome, Smith-lemli-optiz syndrome, Ellis-van Creveld, Holt- Oram syndrome, Noonan syndrome, and Mucopolysaccharidoses (Kaplan, 2002). Errors at any stage in the embryological development of the heart can result inà congenital heart disease.à This development occurs between the third and the ninth week of the gestation period (American Heart [AH], 2010). The heart is formed when a group of cells join to form sheets of tissue, which then join to form a tube whose growth results in the formation of the atria and ventricles (AH, 2010). The resulting tissue undergoes twists and turns while the atria, ventricles and truncus undergo septation.à The antrioventricular canal and conus align the portions of the heart in a manner that allows smooth blood flow. If any error occurs during this process, then heart complications such as the congenital heart disease result (AH, 2010). Incidences of congenital heart disease are on the rise according to recent studies. Data from researchers in the western industrialized world for instance indicate that the incidence of the condition has increased from about three to five per every one thousand live births to about twelve per every one thousand live births. Some researchers though argue that this increase can be attributed to technological advances which have seen the invention of more sensitive detection methods (AH, 2010). à Left to right shunts is the commonest physiology associated with congenital heart disease. This occurs when oxygenated bloodà goes back to the lungs to get re-oxygenated. This return causes a redundancy in the circulation. This leads to an increased venous return from the lungs through the pulmonary veins to the left atrium as well as the left ventricle. This causes the left ventricle to experience volume overload (Larsen, 1993). In a nutshell, left to right shunt causes a volume overload on the left ventricle, as well as pulmonary circulation and reduced systematic output. Left to right shunt lesionsà cause physiological alterations at the ventricular or great artery level. Congestive heart failure can occur between week two and six as a result of a decrease in pulmonary vascular resistances which is accompanied by an increase in systemic vascular resistances as well as physiological nadir in the hemoglobin (Larsen, 1993). Increased left to right blood shunting ultimately results toà pulmonary vasculature which causes hyperplasia of the vessel walls and subsequent hypertension (Kenneth, 1997). Ventricular septal defect is a defect which also occurs in patients with congenital heart disease. In this case, there is a left to right shunt across the ventricular level. During this shunting, blood from the left ventrical is ejected during systole to the pulmonary circulation. This blood causes a volumeà overloadà to the left atrium as well as the left ventricle (Kenneth, 1997). Patent ductus arteriosusà is characterized by a left to right shunt during systole and diastole from the aorta to the pulmonary artery. Owing to the presenceà ofà higher pressure in the aorta as compared to that in the pulmonary artery, the left to right shunt gets continuous.à This causes a volume overload on the left atrium as well as the left ventricle. A large degree of PDA results in pulmonary vascular disease (Larsen, 1993). Truncus arteriosus occurs whereby, the pulmonary arteries are joined to the aorta. Patients who suffer this condition experience higher occurrences of pulmonary hypertension and vascular disease (Larsen, 1993). à Right to left shunt occurs when the deoxygenated blood that goes to the lungs for oxygenation returns back to the body without reoxygenation. One condition associated with this is tetralogy of fallot. This is a condition occurring as a result of the presence of RV outflow obstruction. It results to a right to left shunt across the VSD (Hoffman, 2005). A person suffering from this condition is cyanotic as a result of paucity of pulmonary blood flow. This blood inadequacy results in a smaller left ventricle than the right one owing to a reduction in the pulmonary venous return (Hoffman, 2005). Congenital heart disease is discovered in some cases when the mother undergoes a ultrasound scan during pregnancy. Other cases are not discovered during this scan and therefore theyà are discovered through symptoms when the baby is born (Hoffman,2005). In other cases still, the new born doesnââ¬â¢tà show symptoms of the condition until later years. Some people grow to adulthood without showing symptoms of the condition. Signs and symptoms of this disease include: recurrent lung infections, shortness of breath which is also rapid, fatigue especially during exercises, lack of appetite, low rate of weight gain, sweating while eating, weak pulse in babies and cyanosis color on the skin around the mouth, lips as well as the tongue (Niessen, 2008). à The diagnosis of congenital heart disease can be done before or after birth. Antenatal diagnosis is done through a fetal echocardiography which is a type of ultrasound scanner designed to create a picture of the sides of the heart chambers. This test is doneà in the course of regular antenatal examinations which come during the 18th and 20th week of pregnancy (Niessen, 2008).à Post natal diagnosis is compulsory if the baby presents with some of the signs of the disease such as blue color around the lips, feeding problems, slow rate of growth, etc. methods usedà during this diagnosis include: Electrocardiogram, a test that measures the heartââ¬â¢s electrical activity (Niessen, 2008). This method involves placing electrodes on the skin above the heart which are then connected to a computer. Electrical signals coming from the heart are then analyzed by the computer (Shanley, 2007). Chest x-ray can also be used to detect the disease. This x-ray basically examines if there is excess amount of blood in the lungs or if the heart size is normal. Excess blood in the lungs and a larger heart are signs of the disease (Shanley, 2007). Pulse oximetry is also a detection method that measures the amount of blood present in the childââ¬â¢s blood. A special sensor is placed in the childââ¬â¢s fingertip, ear or toe which sends out light waves. Absorption of the light waves is checked via a computer since the absorption behavior can indicate the oxygen levels in the blood (Shanley, 2007). Cardiac catheterization as a detection method seeks to find out blood pumping behavior. A catheter is inserted in one of the major blood vessels in the groin. Its then pushed to the heart though the assistance of x-rays or MRI scanners. Bloodà pressure readings at different parts of the heart are then recorded by a small pressure monitor attached to the end of catheter (Larsen, 1993) . Treatment of this condition involves administering medicines which can make the heart beat regular incase its not.à The medicines basically mitigate the symptoms before an operation to fix the problem is administered. These medicines include a prostaglandin inhibitor administered toà a premature baby to assist in closing a patent ductus arteriosus (Niessen, 2008).à Heart catheterizationà discussed under diagnosis can also be used to fix the problem. Surgery if necessary is advisable when the baby is strong enough to withstand it. Open heart surgery is carried out if the problem cannot be fixed using a catheter. This surgery aims at closing holes with the help of stitches or patches, repairing or replacing damaged heart valves, andà repairing complex defects (Niessen, 2008). If the problem is too severe to repair, a transplant is recommended. The heart to be used is normally obtained through a donation byà the family of a diseased child (AH, 2010). Nursing care for young ones with congenital heart disease involves basics such as feeding, giving medicines, watching and recording trouble signs, and encouraging them to get involved in their health care program (AH, 2010). Involving the child in the health care program would help them understand why they have a scar, why they need to take medicine, as well as the positive impact play can have to the general wellness of their heart. The child is also helped to understand the need to take certain nutrients such as boiled fish, Mediterranean diet and others which strengthen the heart (AH, 2010). There are several support groups throughout the world for children with heart diseases. Mended little hearts for instance is a support group that helps families with such children (AH, 2010). The Mary bridge child life department offers pre-operative tours for children as well as families scheduled for treatments such as heart catheterization, and cardiothoracic surgery. We also have care pages which are free, private, as well as personalized WebPages pages which patients can visit to obtain any form of advice and care required (AH, 2010). These pages are available at multicare facilities so patients can always keep in touch for any care needed. A patient can post a question as far as care is concerned which is replied with messages of support (AH, 2010). The following is a list of such websites which one can visit for information regarding childrenââ¬â¢s heart care,à diagnosis, treatment as well as support resources: American Heart Association, Childrenââ¬â¢s Heart Institut e, Childrenââ¬â¢sà Hospital Health System of Wisconsin, Childrenââ¬â¢s mercy Hospitals and Clinics, Congenital Heart Defect Online Handà book, Congenital Heart Defects (Texas Heart Institute), Congenital Heart Defects ( Texas Heart Institute)- in Spanish, Congenital Heart Information Network, Heart Centre Online, and Heart Institute for Children (AH, 2010). Children with congenital Heart disease have a poorer quality lifeà than those who are healthy. Children with more severe complications have aà very bad physical and physiological quality of life. For instance, such children are advised against getting involved in certain type of exercises hence they are not free to interact with their peers in every thing. Suchà children also end up with very poor psychological life as a result of limited social interactions with their peers (AH, 2010). In conclusion, this paper has discussed the etiology of congenital heart disease. Genetic factors causing the disease have included: rheumatic heart disease in the mother, Chromosome abnormalities, such as Down syndrome, trisomy 18 and 13, turnerââ¬â¢s syndrome, cri du chat syndrome, wolf ââ¬â Hirsh horn syndromeà and Digeorge syndrome ( deletion 22q11). Genetic syndromes have also been shown to make one more vulnerable to the condition. These have included : Marfan syndrome, Smith-lemli-optiz syndrome, Ellis-van Creveld, Holt- Oram syndrome, Noonan syndrome, and Mucopolysaccharidoses. Environmental factors leading to the disease have included: in take of substances such as lithium by the mother as well as Rubella virus.

Incidences of the disease have been seen to rise with recent research indicatingà about twelve incidences per every one thousand live births. The pathophysiology of the disease has been discussed with effects of both left to right and right to left shunts being analyzed. The effects have included but not limited to : pulmonary vascular disease, pulmonary vasculature which causes hyperplasia of the vessel walls, hypertension andà Congestive heart failure.
