Objectives: Community organization is a resident-led movement aimed at creating fundamental social changes in the community by resolving its problems through the organized power of its residents. This study evaluated the effectiveness of health community organization (HCO), Gangwon’s Health-Plus community program, implemented from 2013 to 2019 on residents’ health behaviors.Methods: This study had a before-and-after design using 2011-2019 Korea Community Health Survey data. To compare the 3-year periods before and after HCO implementation, the study targeted areas where the HCO had been implemented for 4 years or longer. Therefore, a total of 4512 individuals from 11 areas with HCO start years from 2013 to 2016 were included. Complex sample multi-logistic regression analysis adjusting for demographic characteristics (sex, age, residential area, income level, education level, and HCO start year) was conducted.Results: HCO implementation was associated with decreased current smoking (adjusted odds ratio [aOR], 0.73; 95% confidence interval [CI], 0.57 to 0.95) and subjective stress recognition (aOR, 0.79; 95% CI, 0.64 to 0.97). Additionally, the HCO was associated with increased walking exercise practice (aOR, 1.39; 95% CI, 1.13 to 1.71), and attempts to control weight (aOR, 1.36; 95% CI, 1.12 to 1.64). No significant negative changes were observed in other health behavior variables.Conclusions: The HCO seems to have contributed to improving community health indicators. In the future, a follow-up study that analyzes only the effectiveness of the HCO through structured quasi-experimental studies will be needed.

목 적 : 본 연구는 직업성 연 폭로근로자에서 연폭로가 남성 생식기계 독성중 성호르몬에 미치는 영향과 그 정도를 평가하고자 시도되었다.방 법 1998년 하반기에 실시한 일반, 특수건강진단자중 경기도 지역 직업성 연 폭로 근로자 33명과 과거 직업력에서 연 폭로가 없었던 사무직 근로자 33명을 연구대상으로 선정하였다. 연의 생물학적지표로는 혈색소, ZPP, 혈중 연, 및 요중 연을 이용하였으며, 성호르몬으로는 LH, FSH, testos-terone, SHBG 및 FTI를 이용하였다. 연 폭로 지표와 성호르몬과의 상관관계를 조사하였다. 결 과 : 연의 생물학적 지표중 혈색소는 폭로군에서 대조군보다 유의하게 낮았으며, ZPP, 혈중 연및 요중 연등은 폭로군에서 대조군보다 유의하게 높았다. 성호르몬에서 FSH, testosterone, SHBG및 FTI는 모두 폭로군에서 대조군보다 낮았으나 통계적 유의성은 없었다. 폭로군의 성호르몬중에서 연령은 FSH 및 FTI, ZPP는 FSH, 혈중 연은testosterone과 유의한 상관관계가 있었다. 대조군에서 연령은 FSH, testosterone, SHBG 및 FTI와 흡연량은 FSH와 유의한 상관관계가 있었다. 연령군별 폭로군과 대조군의 성호르몬 비교에서 30-39세군의 FTI에서 폭로군이 대조군보다 유의하게 낮았으며 그 밖의 호르몬에서는 모두 유의한 차이가 없었다. 결 론 : 연 폭로군의 FSH, Testosterone, SHBG 및 FTI가 대조군에 비교하여 낮았으나 통계적 유의성은 없었다. 그러나 폭로군에서 연의 생물학적 지표와 일부 성호르몬간에 유의한 상관관계를보였으며 이는 본 연구 대상 근로자의 연 폭로 수준이 일부 성호르몬에 영향이 있음을 보여주는 것으로 판단된다. 향후 이에 대한 지속적인 연구가 진행되어 야 할 것이다. Objectives : This study was performed to evaluate the relationship between biological markers of lead exposure and level of sex. hormones in men occupationally exposed to lead. Methods : In this study, 33 male workers who employed at smelting and battery factories were compared with 33 male workers who were not exposed to lead. As biological markers of lead exposure, hemoglobin, ZPP, blood lead and urine lead were measured. As sex hormones, FSH, LH, testosterone, SHBG and FTI were determined. Results : Hemoglobin level was significantly lower in exposed than in nonexposed group. Level of ZPP, blood lead, and urine lead were significantly higher in exposed than in nonexposed group. There was a trend that level of FSH, testosterone, SHBG, and FTI was lower in exposed than in nonexposed group respectively, but there were no statistical significance. In exposed group, FSH level was correlated with age, ZPP, and blood lead; testosterone level was correlated with hemoglobin, blood lead, urine lead, and SHBG ; and FTI level was correlated with age. Conclusions : Level of some sex hormones were lower in exposed than in nonexposed group but there were no statistical significance between the exposed and the nonexposed group. But level of sex hormones were correlated with several biological markers of lead in exposed group. It suggests that occupational lead exposure might affect sex hormones.

SMAC method is, one of the numerical simulation techniques, modified from the original MAC for the time-dependent variation of fluid flows, The Navier-Stokes equation for incompressible time-dependent viscous flow is applied, and also marker particles which move with the fluid are used. Two-dimensional numerical simulations of the collapse of water column are carried out. This paper has shown the very well computation results of the collapse of water column using SMAC method.

In this paper, the numerical model of the flow analysis by finite element technique is described. The Galerkin method is employed for spatial discretization. Two step explicit finite element scheme is used to discretize the time function, which has advantage in problems treating large numbers of elements and unsteady state. Two dimensional hydrodynamic model considering moving boundary condition is developed. Also the model flume was applied to verify in the idealized water, and the results of this study confirm the efficiency of moving boundary treatment in coastal numerical computation.

In this paper, the finite element method is applied to the calmness simulation of Jeju Harbor. The mild-slope equation as the basic equation if used. The key of this model is that the bottom friction and boundary absorption are imposed. Two numerical computation, rectangular harbor and arbitrary shaped harbor are carried out to show the present study's applicability for the analysis of wave oscillation. These numerical results are compared with the results obtained from the other numerical analysis and experimental data and are in very well agreement. From the application to Jeju Harbor it is seen that wave height is relatively high in 4 pier and 6 pier, and low in 1 pier, 2 pier and 3 pier compared with design manual(MOMAF, 1999).

The effect of wind on the circulation in Jeju harbor was examined using a numerical shallow water model. A finite element for analyzing shallow water flow is presented. The Galerkin method is employed for spatial discretization. Two step explicit finite element scheme is used to discretize the time function. which has advantage in problems treating large numbers of elements and unsteady state. The experiments compare the case considering the effect of wind with the case which do not consider the wind effect. According to wind direction NW winds. velocity of flow vector became slightly stronger in the flow field. The computed results have shown the good adaptability of moving boundary condition and effect of wind. From these studies. it can be concluded that the present method is a useful and effective tool in tidal current analysis.
