We propose an improved M-ISMS(Military-ISMS) model which is based on common ISMS model for regarding military's unique characteristics. Our model focuses on 'Internal Security Audit' and 'Management of external activity' as military circumstances. So, we added the six control new items as internal security audits. Because the confidentiality is more important than availability in military service as compared with private sectors. In addition, we propose some control suggestions for establishing security management standards and keeping level maintenance when it will becomes to lose a value as confidential. The M-ISMS model in this paper has effectiveness which prevents security incidents in advance rapidly throughout a variety of common ISMS's advantages and security incidents of private sectors in consideration of military characteristics.

Purpose: This paper analyzed alternative methods of calculating the conversion factor for nurse-midwife's delivery services in the national health insurance and estimated the optimal reimbursement level for the services. Methods: A cost accounting model and Sustainable Growth Rate (SGR) model were developed to estimate the conversion factor of Resource-Based Relative Value Scale (RBRVS) for nurse-midwife's services, depending on the scope of revenue considered in financial analysis. The data and sources from the government and the financial statements from nurse-midwife clinics were used in analysis. Results: The cost accounting model and SGR model showed a 17.6-37.9% increase and 19.0-23.6% increase, respectively, in nurse-midwife fee for delivery services in the national health insurance. The SGR model measured an overall trend of medical expenditures rather than an individual financial status of nurse-midwife clinics, and the cost analysis properly estimated the level of reimbursement for nurse-midwife's services. Conclusion: Normal vaginal delivery in nurse-midwife clinics is considered cost-effective in terms of insurance financing. Upon a declining share of health expenditures on midwife clinics, designing a reimbursement strategy for midwife's services could be an opportunity as well as a challenge when it comes to efficient resource allocation.

In this study, a mathematical model was suggested to predict the maximum steering torque of a tractor on off-road. The model took into account the characteristics of soil, including the pressure-sinkage and the shearing characteristics as well as the primary design parameters of steering system of the tractor. The efficiency of the developed model was verified via comparison of the maximum steering torque predicted using the model with those measured from steering torque test. The results showed that the predicted maximum steering torques were in good agreement with the measured ones from the steering test on soft soil in which tractor is generally operated. Thus, we concluded that the model developed in this study could be used for prediction of maximum steering torque of a tractor.

Han's model, which is able to analyze optical communication between earth station and geo-satellite as a function of atmospheric conditions and elevation angles. is presented. In Han's model, atmospheric conditions are roughly classified into six basic types; clear sky, cloud, haze, fog, rain and snow. Data rate satisfying for the BER below $10^{-7}$ is analyzed by Han's model in case of up-link and down-link, respectively. Data rate is more limited by up-link than by down-link because the pointing loss caused by atmosphere on the up-link is greater than the spatial coherence degradation caused by atmosphere on the down-link.

This paper aims at developing an analytic model for examining fashion designer's creativity. This research developed the analytic model of fashion designer's creativity adding the specificity of the fashion area to The Systems Model of Creativity by Csikszentmihalyi & Gardener. The analytic model of fashion designer's creativity is composed of 3 elements: the fashion designer, the fashion domain and the fashion field. The detail factors to be examined by each of the elements are as follows. In the dimension of an individual fashion designer, detail factors influencing the manifestation of creativity contain cognitive and non-cognitive abilities (i.e: personality traits, erotic capital) and socio-psychological factors (i.e: family condition, sexual identity, marital status, health). In the dimension of the fashion domain, creativity factors are composed of socio-cultural contexts and paradigms. In the dimension of the fashion field, detail factors refer to a mentor, supporter, competitor and a follower. Fashion designer's creativity manifests itself when detail factors of an individual fashion designer, fashion domain and field interact with each other dynamically.

Purpose: The purpose of the study was to develop and test a model for predicting problem gambling in speculative game users based on Blaszczynski and Nower's pathways model of problem and pathological gambling. Methods: The participants were 262 speculative game users recruited from seven speculative gambling places located in Seoul, Gangwon, and Gyeonggi, Korea. They completed a structured self-report questionnaire comprising measures of problem gambling, negative emotions, attentional impulsivity, motor impulsivity, non-planning impulsivity, gambler's fallacy, and gambling self-efficacy. Structural Equation Modeling was used to test the hypothesized model and to examine the direct and indirect effects on problem gambling in speculative game users using SPSS 22.0 and AMOS 20.0 programs. Results: The hypothetical research model provided a reasonable fit to the data. Negative emotions, motor impulsivity, gambler's fallacy, and gambling self-efficacy had direct effects on problem gambling in speculative game users, while indirect effects were reported for negative emotions, motor impulsivity, and gambler's fallacy. These predictors explained 75.2% problem gambling in speculative game users. Conclusion: The findings suggest that developing intervention programs to reduce negative emotions, motor impulsivity, and gambler's fallacy, and to increase gambling self-efficacy in speculative game users are needed to prevent their problem gambling.

This study investigated the effect a fashion model's self-expression has on stage confidence, commitment, and satisfaction. The differences in stage confidence, commitment and satisfaction were analyzed by comparing the frequency of fashion show experiences. A survey was conducted using convenience sampling of professional male and female fashion models at fashion venues (Dongdaemoon Design Plaza) and model agencies from March 2, 2017 through April 10, 2017. A total of 248 questionnaires were obtained and SPSS 21.0 was used for data analysis. The results of this study are as follows. First, the analysis indicated a fashion model's self-expression factors, including movement, meaning, and individuality, had positively impacted the model's psychological and physical confidence, while acting ability negatively impacted such confidences. Secondly, movement meaning, expressive impulse, and individuality had positive impacts on behavioral commitment. A model's expressive impulse was also found to have a positive impact on cognitive commitment. In addition, acting ability negatively impacted behavioral commitment, while it affected cognitive commitment positively. Third, a high level of psychological and physical confidences about fashion shows, as well as a high level of behavioral and cognitive commitment, had a positive impact on fashion-show satisfaction. There were significant differences in cognitive commitment and fashion-show satisfaction by frequency of fashion show experiences. The findings can be utilized to understand the psychological factors that affect a fashion model's performance in order to increase the model's fashion-show satisfaction. It is also expected to provide useful information to enhance the quality of fashion shows.
