= ABSTRACT = Objectives : Incheon metropolitan city has set a model program of community partnership for hypertensive or diabetic patients detection and follow-up since 2005. This study examines the effects of the model on the compliance and the control of blood pressure or blood sugar level Methods : Telephone-surveys were done for 140 persons selected from 408 patients who were detected newly as hypertensive or diabetic patients at Gangwha-Gun and Seo-Gu in Incheon between January 1st and August 31th in 2006, and finally completed in 110 patients(78.6%). Survey questionnaires included socio-demographic(age, gender, and educational level), health behavioral (smoking, drinking, physical activity, and diet), and therapy-related (registration state, compliance, blood pressure or blood sugar control) variables. Odds ratio and 95% CI were derived from logistic regression model. Results : Registered group exhibited high compliance and well managed blood pressure or blood sugar level. The odds ratio of registration were 5.55(95% CI:1.83~16.89) for compliance and 3.78(95% CI:1.43~9.99) for blood pressure or blood sugar control after adjusting for age, gender, disease, and area Conclusions : It is independently related to compliance and blood pressure or blood sugar control whether the patient is registered or not. To control hypertension or diabetes mellitus in terms of compliance and control state, a community-based registration program through community partnership could be a powerful tool.

Objectives: This study aimed to assess the concentration of perfluorooctanoic acid (PFOA) and perfluorooctanesulfonate (PFOS) in blood and factors controlling their exposure among Koreans. Methods: Study subjects were selected to include 718 members of the general population residing in five metropolitan cities and the Gangwon Province area from August 2008 to January 2009. A questionnaire was administered to investigate lifestyle, socio-demographic characteristics, and other related factors. Blood samples were collected and extracted using solid-phase extraction and anion-exchange methods, and quantified by high-performance liquid chromatograph (HPLC, Agilent 1200 Series) coupled with a Triple Quad LC-MS/MS system (Agilent 6410). Results: Geometric mean concentrations of PFOA and PFOS in the blood were measured as 1.82 and 6.06 ng/ml, respectively. Mean PFOA and PFOS concentrations generally increased with age in both genders. Blood PFOA concentration was significantly different according to such variables as age, family income, residential district, and province. Blood PFOS concentration was significantly different by such variables as gender, age, lifestyle factors such as regular exercise, alcohol consumption, and smoking status. Also, family income, hazardous facilities, job classification, and province contributed significantly to differences in blood PFOS concentration levels. Conclusions: Blood PFOA and PFOS concentrations in Koreans were similar with those found in Japan, the USA, and Germany, but less than those in Australia. PFOA and PFOS exposure seems to be affected by a variety of factors in Korea. Therefore, investigation is required for each factor to assess the relative contribution of different variables.

Purpose: The purpose of this study was to evaluate the survival and success rates of Korean Osstem implants US II Plus, GS II following loading period. Materials and Methods: Dental records were obtained in total 201 patients who were treated with Korean Osstem implants US II Plus, GS II on both maxillary and mandibular anterior and posterior areas in six different clinics for 2 years from January 2007 to December 2008. Total 430 implants were evaluated clinically and radiographically using predefined success criteria prospectively and following results were obtained. Result: US II Plus, GS II implants showed high survival rates of more than 99% and high success rates more than 90% independent of loading period. As a result of cross analysis to evaluate clinical significance between implant loading period and success rate, the P-value of US II Plus was 0.10 (P>0.05), and the P-value of GS II was 0.17 (P>0.05), which showed no statistical significance. Bone quality, smoking, and edentulous state are factors that can affect the survival and success rates following differently loaded implants, but did not significantly affect in this study. Conclusion: These results suggest that selection of loading period of Korean Osstem implants US II Plus, GS II would be done carefully considering implant install area, the quality alveolar bone, the state of edentulous ridge and experience of operator, though they showed clinically good results on both maxillary and mandibular anterior and posterior areas.

This study intended to investigate the characteristics of adolescent drug user in Korea. A questionnaire on adolescent drug use was administered to 1st or 2nd grade 898 students (465 males, 433 females) from 9 senior high schools in Seoul area. The extent of current using six representative drugs such as cigarettes, alcohol, chemical substance inducing hallucination(e,g., thinner, bond etc.), psychostimulant, hypnotic and minor tranqulizer was self-reported. Also their psychological distress, self-concept and individual-related variables such as academic grade, deviant behavior, drug-using peers, the perceived availability of drugs, the degree of family discipline, and the perceived parents' attitude for drinking and smoking were surveyed. Subjects were grouped into six(male) or five(female) subgroups (nonuser, simple experiencer, one kind of drug user, two kinds of drugs user, three kinds of drugs user(male only), minor tranqulizer user) to their extent of drug use. Then ANOVA procedure performed for group comparison of their psychological distress, self-concept and individual-related variables. The results showed that the most popular drugs among adolescents in Korea were cigarettes and alcohol. Minor tranqulizer was used by about 2.8% of male and 7.41% of female subjects. In general abusers showed lower academic grade, more deviant experiences, having more drug-using peers, higher degree of psychological distress, and lower postitive self-concept than nonuser group. According to the results of discriminant analysis, hostility and deviant behavior were reliable predictive variables that distinguished abuser group from nonuser group among the associated variables in this study. These results suggest that some common factors affect drug use of Korean high school students : high school students who have many common risk factors could be abusers more easily. These findings supported risk factor theory that the extent of drug use of adolescents might be associated with general maladjustment in everyday life.

The purpose of this study was to investigate the psychosomatic health status of printers. The 77 printers and 24 control group were analysed about salary, drinking, smoking, education, sex, marriage, age and working age by the THI (Todai Health Index) questionaire. THI was modified from CMI(Cornell Medical Index) and developed by Tokyo University Research Team in Japan. The resuts obtained were summarized as follows. 1. The printers, who get more salary showed high score about mental conplaints, especially, mental irritability(j), nervusness (E), lie Scale(L), aggressiveness(F) and irregualr life(G) and lower salary showed generally high score about physical complaints, especially, mouth and anus (D), digestive symptom(C) multiple subjective symptom(I). 2. According to the printers drinking amount shows the difference, eg nondrinker scored higher on mouth and anus(D), 90mg/week drinker scored higher on multiple subjective symptom(I), digestive symptom(C), depression(K), nervousness(E), and irregular life(G), 91~179mg/week drinker scored higher on impulsiveness(H), mental irritability(J), 270~359mg/week drinker scored higher on respiratory(A), lie scale (L) and aggressiveness (F). 3. The nonsmoker scored high level on mouth and anus(D), mental irritability(J). The previous smoker scored on multiple symptom(I), eyes and skin(B), digestive(C), lie scale(L), and depression(K). The present smoker scored on respiratory(A), impulsivehess(H), aggressiveness(F), nervousness(E), and irregular life(G). 4. According to the printers working age showed almost high score about subjective symptoms on 1~3 year. 5. Men printers high scored on respiratory(A). lie scale(L), aggressiveness(F), women printers scored about mental complaints, especially, impulsiveness(H), mental irritability(J), depression (K), nervousness (E). 6. According to the printers age showed high scored about, below 20 years were lie scale(L). aggressiveness(F), irregular life(G) 21~30years were multiple subjective symptom(I) respiratory (A), eyes and skin(B), mouth and anus(D), impulsiveness(H), mental irritability(J), depression (K), nervousness(E), and over 41 years were digestive(C). 7. Married printers scored high level on eyes and skin(B), digestive(C) and impulsivehess(H), and single printers on respiratory(A), mouth and anus(D), lie scale(L), mental irritability(J). 8. According to education shows the difference, eg high school scored higher on eyes and skin (B), mental irritability(J), depression(K), nervousness(E), collage and over scored higher on multiple subjective symptom(I ), respiratory (A), mouth and anus (D), lie scale (L), aggressiveness (F), irregular life (G), and middle school scored high on digestive (C), impulsiveness (H).

This study was executed to elucidate the degree of satisfaction with working environment and the factors affecting it for workers who are engaged in the composting plants with livestock manure in the Han-river watershed. As an evaluation on site, we applied the self-administered questionaire including general characteristics, working conditions, degree of satisfaction with working environment, and degree of satisfaction with working condition. Simultaneously, we analysed the exposure levels of odor (ammonia, hydrogen sulfide, and odor intensity) in the boundary area of plants. As a result of the study, health condition, odor, work load, dust, and smoking were proved to be the main factors affecting the degree of satisfaction with working environment for workers who are employed in the composting plants with livestock manure in the Han-river watershed. Of them, it was investigated that health condition, odor, and work load accounted for 61.3% of the total degree of satisfaction with working environment and health condition(p$<$0.01), odor(p$<$0.05), work load(p$<$0.05), and dust(p$<$0.05) were statistically significant. It was concluded that the degree of satisfaction with working environment was high for the workers who had good health status and low for the workers who had the relatively considerable work load and were often exposed to odor and dust. Therefore, to increase the degree of satisfaction with working environment for workers who are engaged in the composting plants with livestock manure, the measures that can reduce the exposure levels of odor and dust emitting from the composting plant with livestock manure should be improved.

This study was designed to investigate the effect of bone demineralization and tibia lead on blood lead in retired lead workers. Two hundred thirty five(126 females and 109 males) retired lead workers who worked in 4 different lead factories and 101 non-occupationally lead exposed subjects(51 females and 51 males) were recruited from March 2004 to October 2004. Bone mineral density(BMD) was measured at left calcaneous bone area by broadband ultrasound attenuation(BUA) method with QUS-2(Metra Biosystems Inc, USA). The BUA value transformed into T-score by WHO standard conversion criteria. Tibia bone lead was measured for skeletal bone lead with K-xray fluorescence(K-XRF) and blood lead was analyzed with flameless atomic spectrophotometer. Hemoglobin, hematocrit, serum calcium and iron were also analyzed. In addition, information for smoking and drinking status and basic personal data such as age, gender and lead exposure were also collected using questionnaire inquiry. Blood lead was correlated with tibia lead (r=0.664) and these two variables were negatively correlated with BMD in bivariate analysis. BMD showed significant main effect on the change of blood lead independent to tibia lead without any effect modification of age or gender; the one T-score unit decrease of mineral bone density made $0.43{\mu}g/dl$ increase of blood lead. On the other hand, tibia lead showed effect modification with gender on blood lead; the slope of tibia lead on blood lead in male was steeper than in female and crossed at around zero of tibia lead. In the multiple regression analysis of blood lead and tibia lead on BMD after adjustment of related covariates, only blood lead showed statistically significant effect on BMD. This study confirmed that BMD and blood lead were significantly associated. To verify the causal association of BMD on blood lead and vice versa, further longitudinal studies are needed.

This study was carried out to examine the actual condition of health promotion program through oriental medicine in the health center and to provide basic data to develop proper policy of oriental medical health promotion program for the community people. The data were collected from 26 health centers which have been implementing the oriental medical health promotion program, using selfadministered questionnaire for two weeks from 1 October to 15 October 2006. The results are as follows : Generally, the respondents have the positive views on the level of budget and facilities/equipments of the oriental medical health promotion program in health center. However, they have the negative views on the level of manpower and education/training of the program. And also more than 70% of the respondents have the negative opinion on capabilities of formulating and evaluating the oriental medical health promotion program. The respondents indicated that there was the lack of coordination between the oriental medical health promotion program and existing health promotion in health center, and that low rate of utilizing community resources. With regard to the method of selecting the target group for the program, there are differences according to the each program. Many programs tended to select the target group not through the criteria of life-course and illness group but through the efficiency of selecting group. And many programs such as stroke prevention program, constitutional medicine program, oriental medical prenatal program, oriental medical prenatal and postnatal program, oriental medical child care program are mainly composed of the development of educational program and lecture. Regarding the number of the present oriental medical health promotion programs, around 65% of respondents answered that the number of the programs was many and thus they needed to decrease to the proper level. And with regard to the priority of the need, effectiveness and the satisfaction for each programs, on the whole, Qui gong program, stroke prevention program, area-specialty program and oriental medical home visiting program have high score. In particular, oriental medical quit-smoking program has lowest score. From these results, it requires to develop and improve the oriental medical health promotion program in health center considering the need and characteristics of community.
