This study was aimed to make data how much spent money of medical utilization and direct medical cost. In order to research we were using Korea Health panel 2012 Statistics which data contained Diabetes mellitus client 812 people in age 19. The method of this study was emergency cost, admission medical cost, out patient department cost(client own due, National Health insurance service due, not insurance fee). The result of this study, Diabete Mellitus client were using 198 times during 1 year per 100, total medical direct cost were 859,942 won, 447,359 won, 363,255,508. And admission times were 5.6 times per year, total direct cost was 772,240 won, 4,061,982 won, and 3,298,329,384 won, and out patient clinic using number was 10 times, medical cost total direct cost containing total direct cost was 11,978 won, 26,020 won, and 21,129,240 won. From this research we conclusion that the occurrence of diabetes mellitus can be increased medical cost and direct medical cost and it can be huge burden to client including their family and quality of life in the future. We suggest that in order to prevention and management of diabetes mellitus healthy diet, activity, blood sugar, and blood management should be encouragement.

This study attempts to identify the external and internal factors which affect collaboration motives and investigates their respective impacts from the perspective of foreign direct investment(FDI). Although there has been much research on collaboration motives, so far, few studies have associated collaboration motives with FDI. The findings suggest that while price competitiveness and cost structure uncertainty have a positive and significant impact on collaboration motives, the gross added value to property as well as plant and equipment have a significant negative impact. Furthermore, in the case of gross added value to both property and plant and equipment, managers tend to collaborate with others to enhance the value of these factors. For both FDI and non-FDI firms, internal factors such as price competitiveness and investment within three years are significant determinants for the decision to collaborate. The difference between FDI and non-FDI firms is that for the former, the gross added value to property, an internal factor, is a critical factor, while for the latter, the cost structure uncertainty, an external factor, is critical for collaboration. To summarize, this study suggests the following managerial implication: the enhancement of the internal competency of a firm broadens the window of opportunity for collaboration with others, and consequently provides a chance to boost management efficiency.

A noticeable aspect of Korean firms' outward sequential FDIs to China is that they occur sequentially, which means that they implement the outward FDIs to China with a long-term perspective. To analyze the strategic advantages of sequential investment, we introduce Cournot type quantity competition model. According to the model, three important implications are derived. First, sequential FDIs enhances the Korean parents' production capabilities. Second, the parents are more likely to establish new Chinese subsidiaries as they stay longer in China. Third, the production effect of sequential investments incurs more sequential investments. Some regression models are tested for verifying the predictions. According to empirical results, three important results are found. First, initial entry mode affects the size expansion of the Korean parents. Second, the longer the duration of intial subsidiary in China, the more the sequential investment will be. Third, sequential investments are positively associated with the productivity of the Korean parents.

The role of foreign direct investment (FDI) as a channel of knowledge transfer and on the technological spillovers of know-how to other sectors in the economy is in the middle of this debate. Thus, foreign direct investment may have significant positive effects in reducing residual loadings and environmental pollution. There is an abiding concern expressed by many commentators that countries will lower their environmental standards to attract foreign investment, thereby creating so-called "pollution havens." Others argue that increasing foreign investment could promote "pollution halos" by introducing and transferring more efficient and less polluting technologies. The primary objective of this study is to show the dynamic relationship among pollution loadings, pollution abatement effort, and economic development with explicit consideration of FDI-related effects. This study found when foreign direct investment is evaluated in the model, the environmental pollution level is reduced and expenditure on pollution abatement is increased.

The purpose of this study was to evaluate the influence of the methods of application of the direct analysis method, using the load amplification factor suggested by the KBC 2009 design code, for the evaluation of frame stability. For this purpose, the direct analysis method was performed for three-story-one-bay and five-story-three-bay unbraced steel frames with various notional loads, bending stiffness reductions, and factor B2s. The results of the analyses were compared with the results of the second-order inelastic analysis to evaluate the influence of the applied methods. The scale of the frame, the axial load ratio, and the axial load distribution pattern were added to the main parameters to investigate the external effects. The research results showed that the influence of the methods of application of the direct analysis method is not significant in the case of the required axial strength and the application of the additional notional loads; and that the application of the factor B2 with the story stiffness concept to the direct analysis method is appropriate for the required flexural strength.

Medical oversight (MO) means the advice and direction provided by a physician to rescue workers who provide medical care or carry patients at the scene of an emergency. The purpose of this study was to investigate the utilization of MO and related factors among some 119 rescue workers in Gwangju. A self-reported questionnaire was completed by 153 rescue workers in these 119 safety centers. The data were analyzed by SAS version 9.3. Overall 82.4% of the subjects utilized MO during the past month. In the multiple logistic regression analysis, the married subjects (OR = 3.87, 95% CI = 1.22~12.27), level 1 emergency medical technicians (OR = 2.87, 95% CI = 1.02~8.09), and subjects who treated cardiovascular emergency patients (OR = 9.19, 95% CI = 1.87~45.08) had significantly higher odds ratios for the utilization of MO. The experience of MO accounted for 82%. The development of strategies and education plans taking these results into consideration will help to improve the utilization of MO.

In this paper, we propose setting measurement point in the 3D scan data based on the manual measurement data. The optimal 3D body scan postures and measurement points for automatic measurement of breast were set up. The outer breast point may be different depending on the body shape or standing posture as it is on the line connected from the bisecting point of the lateral waist thickness to front armpit point. Therefore, it is necessary to consider the breast-related outer point proposed in this study. And many researches need to reduce the differences between MAM and 3D dimension items associated with the upper breast point. When measuring depth, the difference by pressing in MAM should be taken into account. And the differences in flexion depending on breast type can make a difference in the 3D measurement. So the measurement method in 3D scan should be further studied depending on the types of breast and verified by multiple subjects.

NSRPM (Neyman-Scott Rectangular Pulse Model) is one of the common model for generating future precipitation time series in stochastical hydrology. There are 5 parameters to compose the NSRPM model for generating precipitation time series. Generally parameter estimation using moment has some problems related with increased objective functions and shows different results in accordance with random variable generating models. In this study, direct parameter estimation method was proposed to cover with disadvantages of parameter estimation using moment. To apply the direct parameter estimation, generating stochastical data variance in accordance with numbers of precipitation events of NSRPM was done. Both kinds of methods were applied at the Cheongju gauge station data. Precipitation time series were generated using 4 different random variable generator, and compared with observed time series to check the accuracies. As a results, direct method showed more stable and better results.

This study was conducted to analyze the turnover intentions of railway traffic controllers among employees of a domestic railway corporation. Variables influencing job turnover intention included exploited variables (empowerment, job stress, job satisfaction, organizational commitment, exhaustion) that have been actively studied in other fields. The results showed that the empowerment of railway traffic controllers did not directly affect job stress and turnover intention, but had a direct effect on job satisfaction, organizational commitment, and exhaustion. Job stress did not directly affect job satisfaction, organizational commitment, and exhaustion, and job satisfaction did not directly affect organizational commitment, burnout, and turnover intentions. Burnout has a direct effect on turnover intention, indicating that exhaustion of railroad traffic controllers has an effect on turnover intentions. In conclusion, empowerment has a direct effect on burnout and exhaustion has a direct effect on turnover intention. This study suggests that management of empowerment and exhaustion is important for the prevention of turnover of railway traffic controllers.
