Due to the topographical and climatic features of Korea, there is a strong possibility of a landslide. Recently, many landslides, caused by the improper land development, frequently occured at the mountain area every summer. Cheonan has been recognized to be relatively safe against landslide, but with the increased risk factors, systematic analysis of the landslide is required. In this paper, the topographical features of Mt. Seonggo in Cheonan City were extracted using contour maps, and water courses and basin areas in heavy rain were computed using the results. Conclusively, Mt. Seonggo areas were relatively safe in the view points of the length of water courses and rain-inflow, but in case of some narrow areas, sustainedly observation was required. Meanwhile, a contour map is proper to analyze the risk of landslide in the 1'st level in that it is more cost effective than other types of digital map.

This paper analyzed the effect of learning motivation and conation(endurance, effort) on the consultant' entrepreneurship(innovativeness, proactiveness, risk- taking) and competencies(ability, knowledge, attitude), and the mediating effect of the entrepreneurship on the consultant's competencies. The result shows that the learning motivation and conation have a positive impact on the partial factors of the consultant's entrepreneurship(innovativeness, proactiveness) and competencies(ability, knowledge), but not impact on the risk- taking and the attitude. Innovativeness and proactiveness have an positive impact on the consultant's competencies, but not the risk-taking. Innovation and proactiveness fully mediated the effect of learning motivation on the ability, and partially mediated on the knowledge. The effect of learning conation on the ability and knowledge was partially mediated by the innovation, not by the proactiveness. This study shows that the management of the learning motivation and conation, the education of entrepreneurship(innovativeness, proactiveness) are very important for the cultivating the consultant' competencies.

The purpose of this study was to examine the influence of variables of TAM, user characteristics variables, and perceived risk variables on the intention to use mobile payment. Through the combination of characteristics of mobile payment, this study also investigated the effect of various independent variables on the intention to use mobile payment including the moderating effect of self-construal. To verify hypotheses of this study, the hierarchical regression analysis based on responses from 188 undergraduate and graduate students was conducted. The significant findings of this study were as follows: TAM variables, user characteristics variables and perceived risk variables had positive influence on the intention to use mobile payment. Self-construal was found to moderate the effect of the perceived usefulness, perceived ease of use and subjective norm. This study may provide important implications for both academicians and practitioners.

The purpose of this study was identify the factors affecting serum vitamin D deficiency in korean women. This study used the data from the 5th Korea National Health and Nutrition Examinations Survey and analyzed the demographic characteristics, health related factors and serum vitamin D in women aged 19 and over. Data were analyzed using the IBM SPSS 18.0 program. As a result, vitamin D deficiency rate in Korean women was 81.4%. There were significant differences according to age, marital status, region, type of residence, family income, education level. The risk factors of vitamin D deficiency were age, marital status, region, without walking. According to the results of this study, further studies on the vitamin D deficiency factors by age group should be conducted and the stress relieve and physical activity of women should be promoted to prevent vitamin D deficiency.

The study was conducted to identify related risk factor of elderly's suicidal ideation. This study used a cross-sectional design with secondary analysis of the $6^{th}$ 2013 Korea National Health and Nutrition Examination Survey (KNHANES). Data for 1,201 elderlies who aged over 65 years old from the KNHANES were included. Suicidal ideation, general characteristics, physical health, psychological health, EuroQoL, and health behavior were measured. Chi-square test, t-test, and multiple logistic regression were used to analyze this data through the SPSS win 22.0 program. In the results, 7.7% of the elderly had suicidal ideation. The odds ratios of suicidal ideation were significantly higher among those with restriction of activity (OR=1.31, CI=1.40~3.82), those with depression (OR=4.44, CI=1.66~7.40), and those with high levels of stress (OR=9.24, CI=3.48~24.5). Therefore, the activity level, depression level, and stress level need to be regularly assessed in order to prevent suicidal ideation among the elderly.

This study investigates the association between financial reporting strategy and the directors' and officers' liability insurance. Since D&O insurance protects officers and directors against the risks of shareholder litigation, it is possible that, because of moral hazard, managers will be more willing to participate in opportunistic financial reporting such as earnings manipulation when they are covered by a generous D&O insurance policy. This paper examines the association between D&O insurance and financial reporting, specifically whether the purchase of D&O insurance affects earnings manipulation. On the other side, the firms engage earnings management are willing to purchase D&O insurance, this study tests whether earnings manipulation affects D&O purchases using listed firms in Korean stock market from 2006 to 2008. This paper finds that firms with higher discretionary accruals are less likely to purchase D&O insurance implies that managers who are participating in earnings manipulation are not willing to purchase D&O insurance. The relation between discretionary accruals and D&O is significantly negative which indicate D&O insurance purchase does not trigger earnings manipulation rather it alleviates opportunistic reporting behavior.

This study is to find out empirically how the fear of crime is affected by the level of recognition of people. CPTED elements including natural surveillance, access control, utilization enhancement, territoriality securement, etc. Safety of residents could be considered and then increased when we plan, design, and operate a city. In Korea, CPTED is currently being applied to every town. However, it is not systemized and neither efficient, for there are no constraint provisions, and the foreign cases are not specifically customized to the current situation of the country. This study, therefore, aims to find the limits from analyzing related laws and regimes, administrative regulations, and applied cases, and to deduct improvement plans based on examined foreign cases.

The purpose of the study was to determine the general characteristics that affect strokes caused by smoking, to provide basic data and political grounds for preventing strokes. Data were used from the 6th (2015) of the National Health and Nutrition Survey. Among the study participants were 2,146 smokers and 132 strokers. Data were analyzed using SPSS ver. 21.0. The findings of the study were as follows: strokes increased the odds ratio 1.7 times(p<0.001) when smoking was performed, and the risk factors for strokes caused by smoking were statistically significant in age(p=0.008, p=0.10), education level(p=0.003, p=0.008), hypertension(p<0.001), and subjective health conditions(p=0.008). Therefore, it is necessary to develop health education contents using smart devices and a consistent national health policy to reduce the occurrence and risk of stroke.
