Objectives : During March-May, 2000, a measles outbreak occurred at Youngduk, Korea. This county is divided into two areas with different historical and socioeconomic background. The outbreak occurred in one of these areas. We conducted a comparative epidemiologic study on the two areas in order to evaluate the factors related to the epidemic. Materials and Methods : We selected two groups, grades 3 and 5 in a primary schools in each area. We investigated outbreak-related factors using parent-questionnaires, the vaccination history from the student's health record and the records concerning the recent measles-outbreak from the local health center. Serologic test on measles-IgG and -IgM antibody was done. Results : The infection rate was 31.5% for the epidemic area and 3.7% for non-the epidemic area according to clinical or serological criteria (p<0.001). No difference was seen in the measles vaccination rate, residence at the time of vaccination or past measles infection history between the two areas. In the epidemic area, the attack rate for the 4-6 year-old MMR booster group(20.5%) was higher than the non-booster group(32.4%), but was not found significantly. Vaccine efficacy was 29.6% in the epidemic area and 87.0% in the non-epidemic area (p<0.001). The IgG level and positive rate were significantly different between the two areas (median 10727 IU/ml, 98.9% in epidemic area; median 346 IU/ml, 85.9% in the non-epidemic area, p<0.001). However, the IgG level and positive rate between the measles-cases and non-cases were not significantly different. Conclusions : This outbreak took place in mostly vaccinated children. These results suggest that a reduction of herd immunity for immunity failure after vaccination may be one of the feasible factors related to the outbreak pattern in the two areas. The results of the IgG level and positive rate suggest that re-establishment of a normal value for IgG level and of a qualitative method for IgG are needed.

Migrant Worker are rapidly increasing in Korea since 1990. They are nowadays main sources of laborer groups engaging in medium-sized factories. The purpose of this study is to provide the basic information to establish proper oral health policy. Dental caries and periodontal disese are the most common disease that occur in the mouth. Periodontal disease is the most common disease in humans and the biggest reason for the loss of the teeth in the adult population. The CPITIN has been developed jontly by the international Dental Federation and the World Health Organization. CPITN is now an established index of level, of periodontal condition in populations for which specific intervention might be considered. This study was conducted to obtain the information regarding to CPITN of migrant workers located in Daegu, Questionaire survey was carried out for 289 workers from July 9 to August 8, 2006. Total survey was 289, 224 males and 65 females. The result was as follows: First, The number of nationality was 14. The first majority was China as 31.8% Among 14 nationalities were Cambodia 18.0%, Vietnam 12.8%, Sri Lanka 12.1%, Indonesia 7.3%, Nepal 4.2%, the other 13.8%, those who are aged from 20 to 29 were 43.9%, and salary from 1,000,000 won to 1,490,000 won 51.2%.(as for their residence, those who resided) over 3 years were 42.6% and not insured reached 68.5%. Second, more than 93.4% of the subjects need periodontal treatment, only 4.9% of non-smoker was health periodontal states, four times frequency of tooth brushing per a day was 16.7%. Third, 28.7% of migrant workers had experienced visit of dental clinic, and 22.9% had received treatment of decayed tooth. Fourth, It is difficult for them 65.1% of them to visit dental clinic in korea, the First was a communication problem and the second was time. Fifth, Most of them didn't have a oral health education but 85.1% of them said that they wish they attend oral health education. We conclude that the situation of migrant workers was very bad considering their working conditions, circumstances, and health condition. According to this study, more than 93.4% of the people need periodontal treatment. Besides they didn't have accurate knowledge about prevention of periodontal disease. Therefor our considering these facts, the policy of dental health by government should be established for migrant workers.

The purpose of this study was to investigate eating behaviors related to snack and self-purchasing snack (SPS) among elementary school children. Self-administered questionnairs were completed by 352, 5th and 6th grade elementary school students living in 3 different regions which included apartment region in Bundangn, Sungnam (apartment group, n=116), residences in Seodaemun-Gu and Mapo-Gu, Seoul (kang-buk group, n=103) and residence in industrial region in Sungnam (industry group, n=133). The results were as follows: A significantly higher proportion (64.7%) of the apartment group had breakfast every morning than those of kang-buk (48.6%) or industry (52.1%) group (p<0.01). As for the frequency rate of snack and self-purchasing snack (SPS), 53.9% of the subjects answered taking snack more than once per day, 22.8%, once for few days and 23.3%, almost not. However, 15.5% of the subject had SPS once or more per day, 30.7%, 1-2 times per week and 22.4%, almost not. Those of apartment group showed significantly lower SPS frequencies (p<0.01), since higher proportions answered having SPS 1-2times per week (40.9%) and almost not (31.3%) compared to other groups. The reasons for having SPS turned out to be 'hunger' 54.7%, 'being habitual', 15.9%, 'bing bored', 15.7% and 'with peers' 13.7%. When subjects selected SPS foods, they considered taste (31.5%), price (23.0%), mood at the time (14.1%), sanitorial aspect (10.2%) and quantity (10.1%) rather than nutritional aspect (7.2%). Subjects' pocket money was estimated as 3736 won per week and SPS expense per time as 706 won. But subjects who spent more than 2000 won for SPS expense were significantly higher (33.0%) in apartment group than those of other groups (p<0.01). The favorite snack items that subjects having at home were fruit, ice cream, milk and yoghurt, cookies, ramen and bread in order. And favorite SPS items turned out to be ice cream, cookies, duckbokki, frozen bars, gum, chocholate and candy in order. The frequency rate of SPS were evaluated to be significantly related by several variables: those living in apartment area (p<0.01), those taking breakfast regularly (p<0.01), those of normal weight status by Rohrer index (p<0.05) and those receiving less pocket money (p<0.01) showed lower SPS frequency rate.

We have conducted questionnaire and measured serum liver function tests on 153 patients whom have received a treatment at a local Oriental medicine clinic in Seoul from Sept. 1, 2002 to Dec. 31, 2002. Patients were categorized into the groups of control(10), decoction group(41), herbal group(5), western medicine group(45), and the group taking both herbal and western medicines(55) concurrently or separately. This study was conducted to investigate how these treatment methods can affect the liver functions. Following results were obtained : 1) Most of the research subjects were male(l03 individuals) living in large urban area, with drinking habit, highly educated, and with normal marriage. For the treatment history, 45 individuals received western medicine treatment(28.85%), 46 with Oriental medicine (29.49%), and 55 patients(35.26%) experienced both forms of treatment. 2) Measuring SD of serum liver functions for all the research subjects, T-protein was 6.95(0.73)g/dl, 4.07(0.51)g／dl for albumin, 0.44(0.19)mg／dl for T-bilirubin, 23.18(18.68)U／L for ALT, 27.42(27.43)U／L for AST, and 22l.27(64.58)mg／dl for LDH. 3) Among the research subjects with the liver functions outside of normal range were 0.64% for T-protein, 3.21% for T-bilirubin and ALT, 36.62% for AST, 0.64% for LDH, and none for Albumin. 4) Confusion variables which may affect the liver functions such as age, smoking, drinking, occupation, and residence were eliminated in calculation and no significant differences were witnessed between the control and experiment groups. 5) In measuring affects of treatment duration on the liver functions, no statistical significances were shown in multiple regression's ,${\beta}$(SE) values. 6) The values of odd ratio in the experiment groups compared to the control were in the range of $0.26(0.22){\sim}0.62(1.23)$. but T-bilirubin of the group receiving both Oriental and western medicine was 1.47(1.90) which showed statistical increase(p<0.001). 7) Factors affecting the liver functions are drinking volume per round duration of alcohol intake, western medicine treatment, gender, and age difference caused significant influences. 8) 57 individuals with serum liver functions out of normal range were mostly male, living in large urban area, median age of 38.89, with normal marriage, highly educated drinking less than once a week with less than 2 bottles per round, and with prior treatment in either western or Oriental medicine. Summarizing above results, we can carefully deduce that taking herbal medicine (both decoction and pills) or western medicine doesn't cause much affect in the liver functions. But taking two forms of medication simultaneously or altering dosage affect significant increase in the T-bilirubin level, thus one needs to take precaution when taking both. Further research is needed in this field to verify this evidence.

본 연구는 2004~2017년 동안 금강수계에서 백제보 건설 전 후의 화학적 수질 특성 및 경험적 모델 분석을 실시하였다. 4대강 사업 전후의 표층수의 수질에 대한 비교평가에 따르면, TP의 농도는 보 건설 후 급격히 감소하는 현상을 보였고, 총질소 역시 감소하는 것으로 나타났다. 반면, 식물성 플랑크톤의 1차 생산력의 지표인 CHL-${\alpha}$ 농도와 EC는 보 건설 후 증가한 것으로 나타났다. 즉, 보 구간에서 수체류 시간의 증가로 인해 N, P의 농도는 감소하였지만, CHL/TP 비는 크게 증가하였고, 이로 인해 단위 인(P) 농도 대비 1차생산력은 증가한 것으로 나타났다. 경험적 모델의 회귀분석에 따르면, 보 건설 전 기간에 CHL-${\alpha}$ 농도는 TP와 유의한 관계를 보이지 않았으나(r=0.068, p=0.860, n=58), 보 건설 이후에 두 변수 사이에는 유의한 관계(r=0.6102, p<0.05, n=56)를 보였다. TN 및 이온희석 현상의 지표로 이용된 EC는 계절별 분석에서 장마기에 크게 감소하는 현상을 보이며 강우와 역상관 관계(r=0.5378, p<0.01, n=163)를 보였으나, 계절별 TP과 부유물 농도(SS)는 갈수기에 비해 장마기에 증가하는 특성을 보여 강우와 정상관 관계(r>0.40, p<0.01, n=163)를 보였다. 2018년 현재 보 구간의 완전한 상시방류를 시행할 경우, 향후 수체의 하천화에 의해 TP 농도는 증가하며, 녹조 현상은 감소할 것으로 사료된다.
