Purpose : The purpose of this study was to look at prevalences of abnormal serum aminotransferase levels and abnormal serum total cholesterol levels among adolescents with obesity in Seoul area. Methods : Body mass index[$BMI(kg/m^2)$], serum aspartate aminotransferase(AST) alanine aminotransferase( ALT), and total cholesterol levels were measured in 26,876 adolescents(male : 13,287, female : 13,589) of first grade of high school in Seoul between the ages of 15 and 16 years, enrolled in a large health examination survey by Seoul School Health Center(SSHC) in 2001. Obesity was defined as BMI more than 95th percentile for age and sex and normal weight was defined as BMI between 25th percentile and 75th percentile for age and sex. Abnormal levels of AST, ALT and total cholesterol were defined as more than 95th percentile for age and sex. Results : The BMI at 95th percentile was 28.7 in males and 26.9 in females. The prevalence of abnormal AST levels was higher in obesity group than in normal weight group. In males, those were 23.7% and 3.7%, respectively(P<0.01, $x^2-value$ : 529.2). In females, those were 11.8% and 4.9 %, respectively(P<0.01, $x^2-value$ : 56.3). The prevalence of abnormal ALT levels was significantly higher in the obesity group compared with the normal weight group. In males, those were 33.9% and 1.7%, respectively(P<0.01, $x^2-value$ : 1,693.4). In females, those were 22.3% and 3.9%, repectively(P<0.01, $x^2-value$ : 397.6). The prevalence of abnormal total cholesterol levels was higher in the obesity group than in the normal weight group. In males, those were 16.8% and 3.5%, respectively(P<0.01, $x^2-value$ : 268.3). In females, those were 9.0% and 5.4%, respectively(P<0.01, $x^2-value$ : 14.2). Conclusion : This study revealed that the prevalences of abnormal AST, ALT and total cholesterol level were higher in the obese group than in the normal weight group.

The purpose of this study was to evaluate the effects of a nutrition education program as part of health promoting projects in an elementary school. A total of 168 students in the 4th grade were enrolled in the program for 6 months. A self-administered questionnaire was developed to assess nutrition knowledge and dietary habit. Nutrient intakes and body shape perceptions were measured using 24-hour recall method and self-ratings of body shape figures, respectively. The education program was conducted in various ways, focused on healthy dietary behavior, nutrients' roles and sources, and proper body shape perceptions, etc. After the education program, nutrition knowledge and dietary habit were significantly improved. Dietary habit scores were significantly and positively related to nutrition knowledge levels. Body shape perceptions were significantly and properly changed after the program. Dissatisfaction with perceived current body shape and discrepancy between shapes desired and considered healthy were significantly decreased. But girls still indicated a desire to be leaner than shapes which were perceived current and considered healthy. Nutrient intakes were partly improved by the program, but some nutrients, such as calcium, folate, zinc, sodium and niacin, were still remained deficient or excessive. These findings indicate that enhancement of nutrition knowledge is extended to the improvement of dietary habit. In addition, establishment of proper body shape perception is closely related to healthy dietary habits and is required to good nutrition and health.

College level educational training system for the allied health manpower in the country is one of the oldest junior college education programs, and has been developed at very steady phase. Since the school years of the programs limited for 2 to 3 years by the education related law, qualification of the manpower is insufficient to meet the rapidly changing needs in the field of allied health and medicine. The system is comparable with that of developed countries where 4-year baccalaureate degree programs are basically required to be an allied health personnel. Thus, education and training background of allied health program graduates of the country confronts the barriers in competition and cooperation with the graduates of foreign countries at equal basis. Beside, junior college graduates can hardly find the way through advanced courses at 4-year colleges in their specialties except a few programs such as environmental sicience or courses in hygiene. It has long been sought to develop the education and training programs for junior college graduates. Some of them are already materilized and some show remarkable progress while some need to tackle. Wide opening of the opportunity to enroll extensive education program for the junior college graduates of allied health science majors in 4-year colleges with eventual grant of bachelor's degree for those who successfully completed the programs should soon be substantiated. The study was focused to emphasize the necessity of the extensive education and training for the junior college graduate allied health manpower, and to show possibility of the education program development in connection with the 4-year degree granting education programs. The outcome of the study can be summarized as followings. 1. A total number of graduates from eight allied health sciences related programs of junior colleges by the year of 1995 are 109,320. 2. According to the survey report analysed through questionnaires, 99.7% of respondents including administrative deans and professors of junior colleges agreed with the establishment of extensive education and training programs in junior colleges. 53.9% of administrative deans, 52.9% of professors and 47.6% of the graduates expected that it is possible to learn more about their majors, and to earn bachelor's degree through the extensive education programs. Other opinions include that the programs can provide supplementary opportunities to fortify in the area of basic life science, and development of research and technology. 3. It was also found through the survey that 91.2% of the deans, 87.8% of the professors and 68.2% of the graduates responded that the most appropriate organizations to open the extensive education and training programs for allied health manpower are junior colleges where allied health personnel are taught and trained. The majority of the respondents agreed that the acceptable number of credits offered for the previous 2-year junior college graduates are $50\sim60$, and those for the current 3-year graduates are $20\sim30$ units. 4. It was strongly suggested through the survey that baccalaureate degree should be granted for those who successfully completed the extensive courses. The suggestion was claimed by 94.1% of the deans, 89.4% of the professors and 83.4% of the graduates. 5. The model curricula for the extensive education and training programs for the allied health manpower are designed for the purpose of broad capability in practice, enrichment of knowledge and promotion of proficiency for the self access in the major areas. 6. To meet the universal standards of allied health education and training program, it is recommended that opening of the curricula for the extensive, and as well as intensive, courses within junior colleges(continuation education institute) should be materialized. The special baccalaureate degree programs within junior colleges are also recommended to accommodate the junior college graduates and to grant the degree fellowing successful completion of the courses. As a part of the education revolution in progress, the school years at junior college level should be flexible depending upon the nature of course and trend of the universe. For instance, the school years for the allied health manpower should be extended to two to four years from current two to three years.

Purpose: To evaluate of the clinical usefulness of minimal invasive ulnohumeral arthroplasty in patients with mild to moderate elbow arthritis. Materials and Methods: From January 2000 to December 2008, twenty-nine patients with mild to moderate elbow arthritis underwent minimal invasive ulnohumeral arthroplasty. Among these patients, we reviewed the cases of 24 patients for whom we had follow-up data for at least 1 year. There were 20 males and 4 females with a mean age of 53 years (range: 31~69). We excluded patients with preoperative ulnar neuropathy symptoms and investigated the mean operation time, the joint range of motion, the time required until the start of joint exercise, and the Mayo elbow performance score (MEPS). Results: Passive and active joint exercises were started in an average of 1.8 days (range: 1~4) after surgery; the mean operation time was 38 minutes (range: 25~55). The elbow joint range of motion was 25-104 degrees (extension 0~70, flexion 80~130) preoperatively and was improved 40 degrees on average to 14-133 degrees (extension 0~45, flexion 90~150) after a year of follow up. The average time required until the start of joint exercise was 1.6 days (range: 1~5). MEPS were excellent in 9 cases and good in 5 cases after a year of follow up. Although there was 1 case of delayed wound healing and 7 cases of postoperative edema, they improved spontaneously. Conclusion: For patients with mild to moderate elbow arthritis, minimal invasive ulnohumeral arthroplasty is a clinically useful surgery since its operation time is short, early joint exercise is possible, and pain is mild.

Recently, It is increasing popularity to research on the soil remediation in aspect of management by reason of the hazardous impact on the contaminated soil in Korea. It was investigated high levels of arsenic salts in soil near abandoned five mines(Darak, Daduk, Jingok, Dalsung, Ilkwang) located in Youngnam area. Arsenic, classified as group A(Human Carcinogens) from IRIS, have shown statistically significant increment in skin cancer with oral exposure. This paper was conducted to predict excess cancer risk value (to the skin cancer) based on multiple pathway such as soil ingestion, dermal uptake and food(plant) ingestion contaminated by arsenic, and also, to identify the remedial goal regarded in future land use. The mine having the highest arsenic level was Daduk(mean : 1950mg/kg) and the next rank was Jingok(1690mg/kg), Ilkwang(352.37mg/kg), Dalsung(86.08mg/kg), Darak(0.83mg/kg). The chronic daily intake to the multiple exposure were calculated using Monte-Carlo simulation regarded in future land use and used q: value was $1.5(mg/kg/day)^{-1}$ to the oral proposed by IRIS(1997). The computated excess cancer risk 95th value to all the mine regarding future land use as residential and rural area were more than $10^{-4}$. If the level of acceptable risk is aimed for 1$\times$$10^{-6}$, it could be used Darak as commercial and industrial area without soil remediation due to the lowest risk value(6$\times$$10^{-8}$ and 3$\times$$10^{-8}$). Computated remedial goal based on 1$\times$$10^{-6}$ of acceptable risk to the future land use as the residential, rural, commercial and industrial area were 0.02mg/kg, 0.003mg/kg, 97.31mg/kg and 194.62mg/kg, respectively.

A series of 25 patients with residual, recurrent, and unresectable gastric cancer received various combination of surgery, radiotherapy (RT), chemotherapy (CT), and hyperthermia (HT). They were placed into 7 categories; 1) CT and HT-14 patients; 2) RT and HT-15 patients; 3) surgery, RT and HT-2 patients; 4) surgery, RT, HT and CT-1 patient; 5) RT, HT and CT -1 patient; 6) RT and CT-1 patient; 7) RT alone-1 patient. Three patients had curative resection. 21 patients received irradiation with tightly contoured portals to spare as much small bowel, kidney and marrow as possible. Hyperthermia was applied regionally once or twice a week for 23 patients using 8 MHz radiofrequency capacitive heating device (Thermotron RF-8). HT was given approximately 30 min after RT 7 patients were treated with CT: 4 patients received HT and concomitant Mitomycin-C; 3 patients received HT and sequential 5-FU+Adriamycin+Mitomycin-C. There was not any treatment related deaths. There was also no evidence of treatment related problems with liver, kidney, stomach, or spinal cord except only one case of transient diabetic ketoacidosis. The tumor response was evaluable in 22 patients. None achieved complete remission.11 ($50\%$) achieved partial remission. The response rate was correlated with total radiation dose and achieved maximum temperature. 9 of 14 ($64\%$) received more than 4000 cGy showed partial remission; especially, all 3 patients received more than 5500 cGy achieved partial response.8 of the 12 patients ($67\%$) who achieved maximal temperature more than $41^{\circ}C$ showed partial response in comparing with $25\%$ (2 of 8 patients, below $41^{\circ}C$). The numbers of HT, however, was not correlated with the response. 3 of the 25 patients ($12\%$) remain alive. The one who was surgically unresectable and underwent irradiation alone is in progression of the disease with distant metastases. The remaining two patients with curative resection are alive with free of disease, 24 and 35 months, respectively. The median survival by response are 11.5 months in responders and 4.6 months in non-responders.

Introduction In order to improve medical education through the introduction of a concept of comprehensive health care of a community, an area surrounding the University Campus was chosen for the Community Health Service Project. It has been on operation for last 4 years with its major emphasis on family planning services, and maternal and child health care. The major objectives of this survey at the area are to obtain: 1) The demographic data, 2) The health need and trend of medical care, 3) The attitude and practice in maternity care to be used for further improvement of the planning and the services of the project. Population and Survey Method Out of three Dongs of the Community Health Service Area, only two Dongs namely Changchun and Yonhee were selected for the survey. Total number of households and population in the area studied was 3,683 and 21,857 respectively. An interview was performed with questionnaire schedule which was recorded by interviewers. This includes the degree of utilization of health services provided by the Community Health Service Program such as family planning, prenatal care during their last pregnancy, delivery history and complications of the delivery as well as the incidence of illnesses in general. Prior to the interview, all interviewers were trained for interviewing technique for two days. The survey was carried out during the period from October December 1967. Results 1) Demographic Data : 41.3% of the population studied were children under age 15 and only 3.5% were over 60 years of age. Crude birth rate and crude death rate of this area studied during the period of November 1966-October 1967 were 20.5 and 7.7 respectively. Infant mortality rate during the same period was 35.9. 50.4% of the 2,832 households fell into the category of middle class, 39.8% to the lower class and 9.5% to the upper class in economic condition. 19.8% of 2,832 householders had no formal education, 22.7% primary school, and 57.5% middle or higher school education. 2) Health Status and Utilization of the Community Health Service: Those who suffered from many illnesses during the month of October, 1967 were 690(4.6% of 14,891 persons). Classification of these patients into the type of disease shown respiratory diseases 27.4%, gastrointestinal diseases 18.1%, tuberculosis 10.9%, skin and genitourethral diseases 4.5% and gynecologic patients 4.5%. Only 55.9% of the patients received medical care at hospital or doctor's clinic. But among TB and gynecologic patients, 70.7% and 72.4% were treated at medical facilities. 10.6% of 2,832 householders interviewed has ever utilized the Community Health Service Program provided by the Yonsei Medical School, Classifying these clients into the type of service, 35.9% utilized the wellbaby clinic, 31.0% the family planning clinic, 14.7% the home delivery care, and the rest utilized other services such as the premarital guidance cinlic and the sanitary inspection service. 3) Maternity Care: 23.6% of 2,151 deliveries were done at medical facilities such as hospital, private clinic, while 76.4% were done at home. Acceptance rate of prenatal care was 32.6% as whole, but 49.6 of 774 women who had the prenatal care service had their deliveries at medical facility. 45.1% of total deliveries were attended by medical and or paramedical personnel. 75.8% of the deliveries of those received prenatal care were attended by medical and or paramedical personnel while only 27.8% of the deliveries of those who did not have prenatal care attended by medical and or paramedical personnel. 49.8% of deliveries of the upper class, 29.8% of the middle class and 9.9% of the lower class were attended by medical and or paramedical personnel. 6.2, 3.3% and 24.8% of mothers reported about their xeperience of edema, coma and fever during the period of trimester of pregnancy and puerperium. 4) Family Planning: The rate of practice of family planning was 27.9%. 31.7% of them were by IUD, 2.9% by oral pill, 15.2% by sterilization and the rest by traditional methods. Those women who had 3 to 4 children had highest(30.2%). Practice rate among the various methods of family planning, oral pill was the most popular method to whom had 2 or less children. In relation between the practicing rate of family planning and living standard, the upper, middle and lower class practiced 37.5, 29.4 and 19.9% respectively.

To provide the basic data for assessment of renal dysfunction related to silicosis, urinary N-acetyl-$\beta$-D-giucobarninidase(NAG) activity known as a sensitive markers for early renal damage were measured in 58 silicosis patients, and control subjects of 40 pulmonary tuberculosis Patients and 51 official workers. The results were summarized as fellows. 1. The values of blood urea nitrogen and serum creatinine in all subjects were within reference limits. But the mean value of urinary NAG activity($7.25{\pm}7.31U/g\;creatinine$) was beyond reference value and more sensitive test than others. 2. The mean value of urinary NAG activity in silicosis group was $11.98{\pm}9.05U/g\;creatinine$ and significantly higher than in tuberculosis and healthy group(p<0.01), but the mean values of NAG activity in tuberculosis and healthy group were not different(p>0.05). 3. The value of NAG activity in tuberculosis had a tendency to be increased according to severity of disease, but that was not significant(p>0.05). The value of NAG activity was increased significantly by use of nephrotoxic antituberculosis drugs(p<0.05). 4. The value of NAG activity in silicosis had a tendecy to be increased according to the size of nodule, use of nephrotoxic antituberculosis drugs and shortness of onset duration, but the increase was not significant(p>0.05). 5. After excluding the users of nephrotoxic antituberculosis drugs, the mean values of NAG activity in healthy control and in tuberculosis control were same as 3.63 U/g creatinine and 3.60 U/g creatinine, respectively. But the mean value of NAG activity in silicosis group was remarkably increased as 10.90 U/g creatinine(p<0.01). As above results, even though there are no abnormal finding in screening renal function test, silicosis can be related with renal dysfunction. And it will be very useful to apply urinary NAG activity in health management of workers exposed to dust.

This study was conducted to investigate the repeat test rate for diagnosis at a tertiary hospital for the outpatients who were referred themselves to the hospital by the clinics and other medical facilities. The study population consisted of 498 patients who visited outpatient department of internal medicine, general surgery, orthopedic surgery and neurosurgery in the hospital between March 16 and April 11, 1992. This study was surveyed by the questionnaire about the tests for diagnosis at first level medical facilities, and then, was investigated by the medical record about the tests for diagnosis at a tertiary hospital. The proportion of test among the patients who utilized the first level medical facilities was 20.9% for the X-ray test, 10.6% for the urinalysis, 9.0% for the electrocardiogram, 3.4% for the computer tomogram and 6.4% for the ultrasonogram. At the tertiary hospital, the X-ray test was 45.2%, the liver function test was 24.1%, the urinalysis was 19.1%, and the electrocardiogram was 15.7%. The proportion of patients who possessed results of test for diagnosis at the first level medical facilities was 76.5% for the computer tomogram, and 31.3% for the ultrasonogram. As the repeat test rate between the first level medical facilities and the tertiary hospital, the thyroid function test was the first rank as 71.4%, the second rank was the routine CBC as 67.9%, and the third rank was the X-ray test as 64.4%. But among the patients that brought the result for tests at the first level medical facilities, the repeat test rate was as follow : the routine CBC was 75.0%, the liver function test was 72.1%, and the computer tomogram was 15.4%.

This study is conducted to evaluate economical value of Jeju grassland and validity of its preservation, and draw up several measures to support. To measure its economical value, this study examined its environmental value and social and cultural value. For environmental value, this study used replacement method while it applied CVM method, a widely used method, to assess social and cultural value and two-level two-best choice selection method, which ask questions by assuming virtual circumstances to avoid reflecting some biased opinions. Jeju grassland has multiple functions-environmental functions such as preventing soil corrosion and flood, handling animal excrement, and purifying air, and social and cultural functions such as promoting physical and mental health and providing recreation places. From the results of the feasibility study, Jeju grassland's annual multiple functions are assessed to have a total $397,115{\sim}418,995$ million won worth. In addition, it is found that Jeju visitors recognize Jeju grassland for its functions to contribute to public interests. That is, they think it can provide attractive views and educational and recreational places and promote emotional development. Especially, many people presented their ideas that it be continuously preserved since it is worthwhile for us and our next generations. To preserve grassland's cultural resource, which create a huge economic value like this, the Government has to support a certain amount of financial aid for turning to a better grassland environment and its maintenance to realize environment-friendly livestock farming on Jeju Island and promote its tourism industry and consequently, add more value to Jeju.
