X선 발생장치의 정도관리는 의료기관의 설립형태에 따라 가장 큰 차이가 있으며, 장치의 보유율은 1차 의료기관에서 가장 많이 보유한 반면 정도관리에 대한 인식과 관리는 소홀하다 할 수 있다. 본 연구에서는 2010년 1월 4일부터 2010년 9월 3일까지 경북 지역을 4개의 권역으로 나누고, 각 시별로 4곳을 임으로 선정하였다. 전체 16곳에 있는 의원급 의료기관 중 10년 이상 된 X선 발생장치를 보유한 8곳과 10년 이하의 X선 발생장치를 보유한 8곳를 그 대상으로 하였으며, 정도관리의 필수 항목 5가지를 시험하였다. 접지 설비 확인시험에서는 10년 이상 된 X선 장치를 보유한 한 곳이 별도의 접지선을 구비하지 않았으며(6.25%), 외장 누설전류시험에서는 모두 적합 하였다. 조사선량 재현성 시험에서는 10년 이상 된 X선 발생장치를 보유한 4곳(25%)과 10년 이하의 X선 발생장치를 보유한 1(6.25%)곳이 부적합 하였다. 관전압의 정확도 시험에서는 10년 이상 된 X선 발생장치를 보유한 5곳(31.25%)과 10년 이하의 X선 장치를 보유한 2곳(12.5%)이 부적합 하였다. 관전류와 관전류량 시험에서는 10년 이상 된 X선 장치를 보유한 3곳(18.75%)과 10년 이하의 X선 장치를 보유한 1곳(6.25%)이 부적합 하였다. 본 연구 결과 10년 이하의 X선 발생장치를 보유한 의원급 의료기관 보다 10년 이상 된 의원급 의료기관의 X선 발생장치의 정도 관리 실태는 심각한 수준 이였다. 검사 결과를 바탕으로 행정적, 기술적인 조치들이 신속하게 이루어져야 할 것이다. 또한 의원급의 사업주나 장치 담당자들의 의식 전환이 필요 하며 그러기 위해서는 오래된 장비이거나 자주 사용하지 않는 장비일수록 정기검사주기를 1~2년 단위로 개정하여야 하고, 정기적인 정도 관리 교육 프로그램을 실시하여야 할 것으로 사료된다.

Objectives : To investigate the knowledge and recognition level of fluorine by teaching career among class teachers, who are primarily responsible for oral health education, despite lack of expertise in oral health, by playing a model role for students through continuous contacts with them, and provide basic elementary data about accurate knowledge and how to correctly use fluorine remarkably effective in preventing dental caries. Methods : A self-administered survey was conducted with 539 teachers at 21 elementary schools in Jinhae City from September 1 to October 15, 2010, drawing the following conclusions. Results : 1. As for the channel for acquiring knowledge of oral health, the highest frequency was found in health programs for respondents with less than 9 years of career, in dental clinics for those with 20 to 29 years of career, and in PR booklets for those with 10 to 19 years and 30 years and longer of career. 2. Use of fluorine-containing toothpaste and fluorine spread is very effective and effective in preventing dental caries got 64.9%, 72.2%, 72.3%, 77.7% and 54.0%, 63.1%, 62.2%, 69.7%, respectively, among elementary school teachers with less than 9 years, 10 to 19 years, 20 to 29 years, and 30 years and longer of career. 3. Intake of fluoride and toothbrushing with fluoric solution is very effective and effective in preventing dental caries got 33.3%, 40.1%, 39.5%, 55.3% and 50.0%, 54.9%, 48.8%, 69.7%, respectively, among elementary school teachers with less than 9 years, 10 to 19 years, 20 to 29 years, and 30 years and longer of career. 4. Use of fluoric tablets is very effective and effective in preventing dental caries got 32.9%, 36.0%, 36.1%, 47.3%, respectively, among elementary school teachers with less than 9 years, 10 to 19 years, 20 to 29 years, and 30 years and longer of career. 5. Most of the elementary school teachers knew the fact that fluorine increases dental resistance to cavity and prevents bacterial growth but gave incorrect responses to properties of becoming basic nutrients or inducing recalcification. Conclusions : Various types of application of fluorine during the elementary-level childhood experiencing the most frequent dental caries will be very useful in improving oral health in the future. It is necessary to enable class teachers to get correct recognition of fluorine through supplementary and job training based on technical knowledge and various educational materials so that they, who are directly responsible for health management through continuous contacts with students, can understand how to correctly use fluorine and get accurate knowledge.

PURPOSE. This study aims to assess and predict lifespan of dental prostheses using newly developed Korean Association of Prosthodontics (KAP) criteria through a large-scale, multi-institutional survey. MATERIALS AND METHODS. Survey was conducted including 16 institutions. Cox proportional hazards model and principal component analysis (PCA) were used to find out relevant factors and predict life expectancy. RESULTS. 1,703 fixed and 815 removable prostheses data were collected and evaluated. Statistically significant factors in fixed prosthesis failure were plaque index and material type, with a median survival of 10 to 18 years and 14 to 20 years each. In removable prosthesis, factors were national health insurance coverage, antagonist type, and prosthesis type (complete or partial denture), with median survival of 10 to 13 years, 11 to 14 years, and 10 to 15 years each. For still-usable prostheses, PCA analysis predicted an additional 3 years in fixed and 4.8 years in removable prosthesis. CONCLUSION. Life expectancy of a prosthesis differed significantly by factors mostly controllable either by dentist or a patient. Overall life expectancy was shown to be longer than previous research.

Biliary atresia (BA) is the result of fibrosing destructive inflammatory process affecting intrahepatic and extrahepatic bile ducts, which lead to cirrhosis and portal hypertension. Kasai portoenterostomy has been the standard operative procedure in biliary atresia. Recently, there has been remarkable increase in the survival rate in cases of BA. However, long-term survivors are not clearly evaluated in Korea. To define long-term prognosis factors of patients who underwent surgery for BA, a retrospective study was undertaken of 10 (37 %) patients surviving more than 10 years among 27 patients who underwent one of Kasai procedures between 1981 and 1995. Hepatomegaly was present in 4 and splenomegaly in 7 patients. Serum bilirubin was normalized at 1 year after operation. Aspartate aminotransferase (AST, GOT), Alanine aminotransferase(ALT, GPT) were normalized at 12 years and alkaline phosphatase(ALP) was normalized at 13.5 years. Cholangitis developed mainly within 5 years after operation so close follow up is needed. Life long follow-up is needed because of progressive deterioration of liver function even after 10 years.

The purpose of this study was to determine the probability of overweight throughout childhood in relation to the presence of overweight at birch or in early childhood, and presence of overweight in children's parents. Weight and height measures were collected at birth and at ages of 7, 10, 12 years from 655 6th grade primary schoolchildren. Childhood overweight was defined as a body mass index at or above the 85th percentile for age and sex, and overweight in children's parents as a body mass index at or above 27. The prevalence of overweight increased with age of the children. Overweight at birth was not associated with overweight at 12 years of ages. However, overweight at 12 years old was already related to overweight at 7 years old. In comparison to non-overweight peers, overweight children at ages 7(OR = 7.64, 95% CI = 4.32-13.51) and 10 years(OR = 19.69, 95% CI = 11.42-33.94) had a higher rick of becoming overweight at 12 years of age. Among children who was overweight at age 7years, 60.7% remained overweight 5 years later, Yearly increment in BMI of overweight children was larger than that of non-obese children (1.15-1.65kg/m$^2$vs 0.50-0.71kg/m$^2$. As compared with the lower case in mealy increment of BMI, the probability of being overweight at age of 12 years was greater in higher case. BMI values at age 7years were positively correlated with BMI values at age of 10 and 127ear,i, and with annual increments in BMI. But those relationships with birth weight were not observed. Children were at greater risk for overweight if at least ogle parent was overweight. The odds ratio for child overweight associated with maternal overweight was 2.41(95% CI = 1,13-5.IS), and those associated with paternal overweight 1.70(95% CI = 0.92-3.17). And parents' BMIs were positively correlated with children's BMI values and yearly BMI increment. In conclusion, overweight at early childhood and annual inclement in BMI can be important in predicting the prevalence of overweight and the risk that overweight will remain after 7 years of age. The risk of being overweight throughout the childhood increases by the parents'overweight.

Objectives : This study was to suggest the basic data to develop the national exam contents for dental hygiene by comparing with those of other country. Methods : Several dental hygiene education course results were reviewed, and analyzed the culture subjects, basic major subjects, educational subjects, national exam contents in 3 or 4 years dental hygiene curriculum. Results : In Korea, grades of culture subjects in dental hygiene curriculum were different between 3 and 4 years education course, mean grades were 10.4, and 34.5 respectively. While there were few different between 3 and 4 years education course, mean grades were 36, and 36.5 respectively in foreign country. In Korea, grades of major subjects in dental hygiene curriculum were similar between 3 and 4 years education course as mean grades of 110, while there were different between 3 and 4 years education course, mean grades were 60 and 80 respectively in foreign country. In Korea, number of major subject was higher in 4 years(n=61) than 3 years(n=54). However, it was lower in 4 years(n=27) than in 3 years(n=33) in foreign country. Total grade number was 129 in 3 years, and 145 in 4 years in Korea, while it was 97 in 3 years, and 116 in 4 years in foreign country. By analyzing 3 years education course, culture subject was 9.5%, basic health was 11.2%, oral biology was 11.2%, clinical dentistry was 20.7%, public oral health was 10.4%, oral hygiene care was 35.9%, management of dental clinic was 9.4%, education was 2.8% in Korea. In USA, dental hygiene examination contains practice work as major part, while theory was thought of as most important things in korea. Conclusions : It is necessary to improve learning course of dental hygiene curriculum on the basis of other country's system, and then it could be possible to development of good quality's national examination contents, thus good quality of dental hygiene personnel would be turned out in Korea.

The purpose of this study is to find out the subjective and objective fatigue level and the characteristics of seamen's physical strength with the service period on board, to have a new understanding of the vocation, and to explore a physical exercising program for the seamen. The questionnaire survey for the seamen who had been in service on the ocean going vessels was conducted and the results are fumed out as the followings. Total number of seamen who had answered the questionnaire was 64 persons and the distribution status of service period group was identified as 16 persons for each of 4 groups； the group was classified as the group of less than 5 years, 5 - 10 years, 10 - 15 years, and more than 15 years. 1. Working conditions Working hours in a week was identified as 44－56 hours(45.3%) and the number of 45.3% of the seamen answered the working hours in week is more than 56 hours. The seamen of 25.0% are unsatisfied or very unsatisfied with their vocation. The seamen of 65.6% are smoking, and 45.3% of them drink. The seamen of 44.,3% drink once or more in a week. And the seamen of 67.2% do not take any exercise in a week. 2. Contribution to the seamen's fatigue and subjective symptom The most contributive factor to the seamen's fatigue was identified as the short of sleeping(21.5%), overwork(19.2%), poor working conditions (18.6%), and the friction in human relations also becomes one the contribution to the fatigue(14.0%). The subjective symptom by fatigue was identified as the feeling of languid, sleepy and tiredness of eyes. 3. Characteristics of the seamen's physical strength and Interrelations The grip strength and back strength of the seamen whose service period is less than 5 years were measured as 40.44kg and 127.8kg. The sit ups in the group of service period less than 5 years was measured as 36.84 times, and the vertical jump for the seamen in this group was measured as 46.55cm. The closed-eyes foot balance was measured as 33.64 seconds in the group of service period between 5 and 10 years, and side-step was measured as 35.31 times in the group of service period less than 5 years. The standing trunk flexion was measured as 10.54cm for the seamen whose service period is between 10-15 years, and the trunk extension was measured as 50.70cm for the seamen whose service period is less than 5 years. And the step test of the seamen whose service period is between 10-15 years was measured as 54.44 numbers, and the number of flickers of the seamen whose service period is less than 5 years was measured as 32.94.
