Objectives: This study was conducted to find out caries preventive effect on permanent teeth among children who brush teeth with fluoride-containing toothpaste by supervised weekly fluoride mouthrinsing program in elementary schools. Methods: The epidemiologic dental survey was performed on the elementary schoolchildren of supervised weekly fluoride mouthrinsing program (FMR) with 0.2 percent neutral sodium fluoride solution and control group in 2007. Caries preventive effect on permanent teeth by fluoride mouthrinsing program were calculated by DMFT index and DMFS index between FMR group and control group. Results: By DMFT index between FMR group and control group, caries rates on permanent teeth of the fourth-, fifth- and sixth-grade children participating in FMR program were 34.1%, 40.8% and 31.5%, respectively. By the DMFS index between FMR group and control group, caries preventive rates on permanent teeth of the fourth-, fifth- and sixth-grade children participating in FMR program were calculated 25.4%, 37.7% and 33.5%, respectively. Conclusions: We suggest that fluoride mouthrinsing program should be developed to all elementary schools to prevent dental caries.

Objective : To investigate the sources, extent and related factors in South Korean doctors. Methods : The study subjects were 934 doctors in Taegu, Kyungpook Province, Korea(540 independent practitioners, 105 employed at hospitals and 289 residents in training). Information concerning job stress was obtained using a 9-item questionnaire. Information regarding related factors such as demographic characteristics(age, sex, marital status), perceptions on the socioeconomic status of doctors and working conditions(work time, on-call days per week) was also obtained by self-administered questionnaire during April and May, 2000. Results : Major sources of job stress included clnical responsibility/judgement factor, patient factor and work loading factor. The job stress score of residents was the highest among three groups. The score was lower in older doctors. The score was low among those who thought doctors' socioeconomic status was not good. The longer the work time, the higher the job stress score was. Multiple regression analysis was conducted to control for the mutual influence of independent variables. In regression analysis, the score of residents was higher than practitioners. Work time and socioeconomic status perception had negative effects on job stress score. Conclusion : The average job stress score of the doctors was high. Age, work type, working conditions and perceptions of socioeconomic status were found to besignificantly related to job stress score. Although the job stress of doctors is somewhat inevitable due to the nature of the doctor's job, control of work time, development of coping tools and other intervention methods are needed to reduce job stress of doctors. Further studies are required to understand the characteristics of iob stress and reduce the job stress of doctors.

Background: During and after the Fukushima nuclear disaster (FND), many parents were concerned about the effects of radiation on the health of their children. Purpose: To clarify the factors that influenced general workers living with children and the effect of child age groups in implementing preventive behaviorsagainst radiation following the FND. Materials and Methods: A descriptive study of preventive behaviors among general workers was carried out 3-5 months after the nuclear disaster. The subjects were 1,394 regular workers, who took part in radiation seminars run by the Fukushima Occupational Health Promotion Center between July and September, 2011. In total, 1,217 responses were submitted, of which 1,110 were eligible for the present study. This anonymous questionnaire survey inquired about the presence and age of children in the household and about radiation preventive behavior implemented after the FND. The contribution of each variable was assessed by logistic regression analysis. Results: General workers in Fukushima who lived with younger children performed more preventive behavior against radiation during and after the FND. In particular, both location-related and daily routines were practiced significantly more frequently (p<0.01) by workers living with a child in the age ranges of 0-6 (8 of 10 items) and 7-12 (5 of 10 items). Conclusions: This is the first study to assess the positive association between living with children by age group and increased preventive behavior against radiation implemented by general workers after the FND.

To evaluate the effect of manganese on the respiratory system, we investigated the respiratory symptoms of 63 male workers exposed to, fume containing manganese (Mn), iron (Fe) and silica (Si), and compared them with those of 66 male workers not exposed to the fume in a manganese alloy smelting factory. The prevalence ratios of the seven respiratory symptoms were not different between two groups. The presence of any respiratory symptom was not related with the age, duration of employment, smoking status of workers, and exposure to fume. In furnace workers, it was not related with the airborne Mn, Fe, and Si concentration in the total or respirable fume. Airborne Mn concentrations of all 4 furnaces in the respirable fume were below $1mg/m^3$. There were two suspicious cases of pneumoconiosis among furnace workers and one definite case(1/2) among casting workers who were not exposed to fume. The above results suggest that the exposure to the low airborne Mn concentration is not related with respiratory symptoms and pneumoconiosis. However, it is necessary to study the respiratory effects of Mn using the symptom questionnaire with consideration of the severity and persistence, of symptoms and the time interval from exposure.

The notion that dental amalgam is a potential source of mercury exposure remains a controversial issue. However, there are few epidemiological analyses that have addressed whether this occurs in children. We aimed in our current study to identify the relationship between dental amalgam filling surfaces and the blood mercury levels in a cohort of 711 South Korean children aged between 8-9 years. Oral examinations were conducted to detect the number of amalgam filling surfaces on the teeth of these individuals. Blood samples were also taken from these children to assess the levels of mercury accumulation in the body. The amalgam filling surfaces were classified into four groups based on their number: 0 (n = 368), 1-5 (n = 219), 6-10 (n = 89), and 11+ (n = 35). The blood mercury levels in the children with more than 10 amalgam surfaces was 0.47 ${\mu}g$/L higher on average than those with no amalgam surfaces after adjusting for the frequency of fish or seafood consumption, age, and gender (P < 0.05). We found from our data that a higher number of dental amalgam fillings correlated with a higher blood mercury level in Korean children. Further studies are needed to investigate whether these elevated mercury levels exert neurotoxic or nephrotoxic effects.

Objectives: The purpose of this study was to estimate the mediating effect of subjective unmet healthcare needs on poor health. The mediating effect of unmet needs on health outcomes was estimated. Methods: Cross-sectional research method was used to analyze Korea Health Panel data from 2011 to 2015, investigating the mediating effect for each annual dataset and lagged dependent variables. Results: The magnitude of the effect of low income on poor health and the mediating effect of unmet needs were estimated using age, sex, education level, employment status, healthcare insurance status, disability, and chronic disease as control variables and self-rated health as the dependent variable. The mediating effect of unmet needs due to financial reasons was between 14.7% to 32.9% of the total marginal effect, and 7.2% to 18.7% in lagged model. Conclusions: The fixed-effect logit model demonstrated that the existence of unmet needs raised the likelihood of poor self-rated health. However, only a small proportion of the effects of low income on health was mediated by unmet needs, and the results varied annually. Further studies are necessary to search for ways to explain the varying results in the Korea Health Panel data, as well as to consider a time series analysis of the mediating effect. The results of this study present the clear implication that even though it is crucial to address the unmet needs, but it is not enough to tackle the income related health inequalities.

유럽의 많은 의과대학들은 사회의학을 교과목으로 개설하고 있으며, 미국에서는 일부 의과대학들이 사회의학을 department의 명칭에 사용하고 있다. 그러나 한국에서는 사회의학의 도입이 제대로 진행되지 못했다. 이는 한국 의학에 지대한 영향을 미친 미국 의학계가 한동안 그 용어와 원리를 수용하지 않았었기 때문일 것이다. 이러한 상황 인식을 바탕으로 1) 사회의학의 기원과 진화에 관하여 기술하고, 이어서 2) 한국 사회의학의 실상에 대하여 간략히 논의할 것이다. 사회의학은 1848년 프랑스와 독일에서 창시되어, 국제적으로 다양한 발전 과정을 거쳤다. 사회적, 경제적 여건이 건강, 질병 및 의료서비스에 미치는 영향이 심대하며, 따라서 그에 대한 과학적 연구가 필요하다는 것이 사회의학의 핵심적 개념에 속한다. 한국에서는 사회의학이 거의 사용되지 않는 용어지만, 그 내용은 의과대학 예방의학 교과과정에 도입된 상태이다. 그러나 이러한 내용적 수용은 사회의학에 대한 논의와 이해에 근거해서 이루어진 것이 아니므로 그 의의와 가치의 전달에 한계가 있다. 따라서 예방의학과 사회의학의 연계관계를 분명히 밝히고, 체계화하는 노력이 필요하다. 구체적으로는 의과대학 예방의학 과목의 명칭을 많은 나라에서처럼 예방사회의학으로 변경하고, 명칭에 부합하도록 내용을 조정 보완하는 방안을 검토할 필요가 있다.

본 논문은 교량의 예방적 유지관리 효과를 생애주기비용 절감 측면에서 분석 하였다. 예방적 유지관리는 현재 실시되고 있는 대응적 유지관리 전략과 대비 되는 유지관리 전략으로 교량의 열화지연을 통해 궁극적으로는 교량의 사용수명을 연장 시키며 생애주기비용을 절감시키는 유지관리 전략이다. 이러한 예방적 유지관리 효과를 분석하기 위해 교량의 공용연수에 따른 건전도 점수 변화 모델과 FHWA 자료를 바탕으로 한 국내 고속도로 교량의 건전도 점수에 따른 보수 보강 비용 모델을 제시 하였다. 제시한 복수의 모델과 국내외 참고 문헌을 바탕으로 제안된 예방적 유지관리 항목(청소와 도장)의 비용과 주기를 활용하여 사용수명 100년까지의 표준교량($1,730m^2$/교량) 당 생애주기 비용과 향후 20년간의 고속도로 총 유지관리 비용을 산정 하였다. 분석 결과 100년간 예방적 유지관리 활동으로 인해 교량 당 5억원의 절감효과를 볼 수 있으며 현재 예방적 유지관리 활동을 실시할 경우 20년 후(2035년)에는 총 1,837억원, 즉 연간 약 92억원의 비용 절감효과를 볼 수 있는 것으로 분석 되었다.

The purpose of this study was to identify the effects of cancer prevention and early detection education on cancer-related knowledge, attitudes, and preventive health behavior of middle-aged women in Korea. The research design was a nonequivalent control group pretest-posttest design. The subjects of this study were 38 middle-aged women from a church in Taegu. An Experimental group of 19 and a control group of 19 women were studied. The study was conducted from September 21, 2000 to October 27, 2000. The cancer prevention and early detection education had been provided to the experimental group for 2 weeks. The contents of the education program for the third most prevalent cancer of Korean women were : 'the risk factors of cancer', 'the early symptoms of cancer', 'the diagnostic test for cancer detection', and 'the cancer prevention methods'. The instruments used for this study were modified, cancer-related knowledge, and attitude, preventive health behavior tools of Suh et al.(1998). Data were analyzed using descriptive statistics, $\chi^2$-test, t-test, ANCOVA with SPSS WIN 9.0/PC. The results were as follows : 1) Hypothesis 1 that the women who get cancer prevention and early detection education will have higher scores of the cancer-related knowledge than the women do not get cancer prevention and early detection education was accepted(F=4.732, p=.037). 2) Hypothesis 2 that the women who get cancer prevention and early detection education will have higher scores of cancer-related attitudes than the women do not get cancer prevention and early detection education was rejected(F=.118, p=.733). 3) Hypothesis 3 that the women who get cancer prevention and early detection education will have higher scores of cancer-related preventive health behavior than the women who do not get cancer prevention and early detection education was rejected(F=2.250, p=.143). On the basis of the above findings, the following recommendations are suggested : 1) It is necessary to identify the variables affected on cancer-related knowledge, attitudes and preventive health behavior. 2) It is necessary to develop a well organized cancer prevention and early detection education program to change cancer-related attitude and preventive health behavior.
