The purpose of this study was to investigate the convergence factors affecting disease management efforts of the middle-aged population who have comorbidities of all three metabolic diseases: type 2 diabetes, hypertension, and dyslipidemia. This study used raw data from the 2015 community health survey(CHS). A multiple hierarchical regression analysis was performed that the included variables explained 20.1% of the variance in weight-loss efforts, 6.8% of exercise efforts and 5.3% diet efforts respectively. This study revealed associations among gender, socioeconomic status, and behavioral habits of smoking and drinking with disease-management efforts. It is important to design a health service or supportive intervention with consideration of multiple factors for patients with multiple metabolic disease.

The purpose of this research was to examine the effect of dance sports for twelve weeks on physical self-efficacy in post-menopausal depression obese women. A total 38 women participated in this study, and they were divided into three groups: mild-depression group(n=9), light-depression group(n=14) and control group(n=15). For the exercise program in this study, a dance sports program performed at an intensity of heart rate reserve 50~80%, 60 minutes of exercise time, and the frequency of 3 times a week. Physical self-efficacy for mild-depression group after 12-week dance sports program was significantly increased compared to before the exercise. Although light-depression group and control group didn't show significant increase in physical self-efficacy, dance sports is expected to act positively on mental stability, such as depression and hope used as an effective tool to improve the quality of life. Furthermore, we expect a convergence is achieved between the sports science and medical research sectors.

This research was a review and analysis of published articles and theses in Korea on Intervention Programs for patients with Diabetes Mellitus. A comprehensive search of databases was undertaken(Korean studies, Riss4u). using research terms such as"diabetes", "diabetes and education" "diabetes and exercise", "diabetes and intervention", "diabetes and education or exercise." 53 studies were analyzed focusing on type, application method, dependant variable and effect using descriptive statistics. 8 intervention type and 113 dependant variables were used. The most frequently used applied education and counseling and glycometabolism, self-care, self-efficacy the most frequently used dependant variable. The effects of dependant variables no effect or were different effects. Further reserarch in the digital convergence should requires the consideration of Structured content and exercise and the effect of the measurement variables, including the psychological variable effect.

The nonlinear finite element program has been developed to analyze the design performance of an artificial hip prosthesis and long term behavior of a treated femur with stems made of composite material after cementless total hip arthroplasty(THA). The authors developed the three dimentional FEM models of femoral bone with designed composite stem which was taken with elliptic cross section of 816 brick elements under hip contact load and muscle farce in simulating single leg stand. Using the program, density changes, stress distributions and micromotions of the material femoral bone were evaluated by changing fiber orientation of stems for selected manufacturing method such as plate cut and bend mold. The results showed that the composite materials such as AS4/PEEK and T300/976 gave less bone resorption than the metallic material such as cobalt chrome alloy, titanium alloy and stainless steal. It was found that increasing the long term stability of the prosthesis in the femur could be obtained by selecting the appropriate ply orientation and stacking sequence of composite.

Laminated composite plates have shown their superiority over metals in applications requiring high specific strength, high specific modulus, and so on. Therefore, they have used in various industry. However, they have poor resistance to impact compared to typical metal materials. So, many researchers have investigated about impact behavior of laminated composite plate. To investigate impact behavior of laminated composite plate, we have to calculate contact force between impactor and laminated composite plate at the first. Impactor's equation of motion, plate's equation of motion and correlations for indentation were solved to know the contact force at the same time. In this study, low velocity impact behavior of composite plate was investigated using the finite element program which is involved the classical Hertzian law, Sun's law and Sun & Yang's experimental law and Sun & Tan's experimental law considering the stacking method.
