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.

In this paper, a numerical model of the tidal flow problem by using finite element method is described. By using this method, the boundary conditions can easily be treated and nodes can also taken up arbitrarily. To discretize the differential equation, we have used the Galerkin method in space direction and two-step explicit method, so-called the Kawahara scheme, in time direction. Also, shallow ong wave equation considering the bottom friction, eddy viscosity and Coriolis force is employed. In this paper, finite element method by moving oundary is developed. By the numerical computation of the Cheju jarbor, we can find the finite element method to be a powerful analytical procedure to tidal flow problem.

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.

Arteriovenous fistula of uterus is rarely reported disease. This vascular malformation is very dangerous condition because Dilatation & curettage can cause massive uterine bleeding without accurate diagnosis. The diagnosis is made by angiography, gray scale ultrasonography, color and duplex doppler ultrasonography, computed tomography, and magnetic resonance imaging is helpful. Especially color and duplex doppler ultrasonography is allows convincing detection and diagnosis of arteriovenous fistula. Recently transcatheter uterine artery embolization is treatment of choice. We have experienced a case of arteriovenous fistula of uterus. Which is presented with a brief review of literature.

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).

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.

Bathing beaches may be the one of the resorts in popular, which peoples can easily access in summer. Three beaches located in Jeju island are observed on natural conditions using coastal engineering technique. Also the satisfaction indexs of the sand size. wave height. water temperature. transparency and bottom slope are surveyed. The results obtained can be utilized making an artificial bathing beach.
