"안전보건경영시스템을 구축하기 이전에는 사고발생에 대한 불안감이 항상 마음 한편에 자리 잡고 있었습니다. 하지만 시스템 도입 후 직원들이 스스로 작업환경의 위험성에 대해 평가를 하고 개선 대책을 수립 실천하는 모습을 보면서 현장의 안전관리에 자신감을 갖게 됐습니다."

Risk management should be controlled systematically by effectively evaluating and suggesting countermeasures against the various risks which are followed by the change of the society and environment. These days, enterprise risk management became a new trend in the field. The first step in risk analysis is to recognize the risk factors, that is to verify the vulnerabilities of loss in the security facilities. The second step is to consider the probability of loss in assessing the risk factors. And the third step is to evaluate the criticality of loss. The security manager will determine the assessment grades and then the risk levels of each risk factor, on the basis of the result of risk analysis which includes the assessment of vulnerability, the provability of loss and the criticality. It is of great importance to put the result of risk analysis in mathematical statement for a scientific approach to risk management. Using the risk levels gained from the risk analysis, the security manager can develop a comprehensive and supplementary security plan. In planning the risk management measures to prepare against and minimize the loss, insurance is one of the best loss-prevention programs. However, insurance in and of itself is no longer able to meet the security challenges faced by major corporations. The security manager have to consider the cost-effectiveness, to suggest the productive risk management alternatives by using the security files which contains every information about the security matters. Also he/she have to reinforce the company regulations on security and safety, and to execute education repeatedly on security and risk management. Risk management makes the most efficient before-the-loss arrangement for and after-the-loss continuation of a business. So it is very much important to suggest a best cost-effective and realistic alternatives for optimizing risk management above all, and this function should by maintained and developed continuously and repeatedly.

Businesses have to survive and thrive in both domestic and international environments. In order to resolve these problems, new alternatives have been presented. These include the importance of women's resources and entrepreneurship of female CEOs. The sensibility, delicacy, creativity as well as the intuitive power of female CEOs, actively enables them to cope with the ever-changing environment. Because of the rapidly changing circumstances, the above mentions women's attributes are highlighted thus, causing women's roles in society to shift from their traditional tendencies to finding careers and their own identities. Due to this change in social roles, social interest and the values of female CEOs are being reevaluated. Accordingly, the conceptual consideration of female entrepreneurship (innovation, enterprise, risk sensitivity) as well as the factors to be considered for the entrepreneurship of female CEOs in order to promote knowledge management performance was derived in this research. The deducted implication of this research is that generally, the enterprise and risk sensitivity of entrepreneurship affect the knowledge management performance of female CEOs. It is therefore proved that in the case of female CEOs, entrepreneurship and self-efficacy are linked, allowing them to achieve the desired outcome for a specific task performance. Female CEOs are capable of company management through the mediating process of their enterprise, risk sensitivity, and self-efficacy and with faith in their knowledge management, will be able to achieve high performance. Therefore, using strengths and nature peculiar to women, women's economic activities derived from knowledge management based on entrepreneurship will not only help overcome the long-term economy crisis but also lead to high economic growth and development. This will be a dynamic force for the nation's new growth with financial means. The comparative study of existing results will also contribute in suggesting the direction of policies that will enable the success of female CEOs in entrepreneurship.

Chronic diseases such as hypertension require a differentiated approach according to age and life cycle. Chronic diseases such as hypertension require differentiated management according to the life cycle. It is also known that the cause of hypertension is a combination of various factors. This study uses machine learning prediction techniques to analyze various factors affecting hypertension by life cycle. To this end, a total of 35 variables were used through preprocessing and variable selection processes for the National Health and Nutrition Survey data of the Korea Centers for Disease Control and Prevention. As a result of the study, among the tree-based machine learning models, XGBoost was found to have high predictive performance in both middle and old age. Looking at the risk factors for hypertension by life cycle, individual characteristic factors, genetic factors, and nutritional intake factors were found to be risk factors for hypertension in the middle age, and nutritional intake factors, dietary factors, and lifestyle factors were derived as risk factors for hypertension. The results of this study are expected to be used as basic data useful for hypertension management by life cycle.

LG 경제연구원이 발표한 보고서에 의하면, 국내 인터넷 쇼핑몰 시장이 2003년에는 1조 7000억원 규모를 상회할 것으로 예측되고 있다. 그러나 급격한 성장세를 보이고 있는 인터넷 쇼핑 시장규모에 비해 아직까지도 소비자와 관련된 연구는 많이 부족한 실정이다. 특히, 인터넷 쇼핑과 관련된 자료를 보면 소비자들은 인터넷을 통한 제품구매 시 여전히 불안감을 가지고 있는 것으로 나타나고 있음에도 불구하고 인터넷쇼핑에서의 지각된 위험에 대한 연구는 간헐적으로 이루어지고 있을 뿐이며, 이들 연구 역시 인터넷 쇼핑에서의 지각된 위험과 그 유형을 규명하는 데에만 초점을 맞추고 있어 지각된 위험수준에 따라 소비자의 구매행동이 어떻게 달라지는지에 대해서는 논의가 제대로 이루어지지 않고 있다. 따라서 본 연구에서는 지각된 위험수준에 따른 소비자의 구매행동을 브랜드와 가격 의존도로 한정시켜 이들 요인들간의 상대적 중요성 지각을 살펴볼 것이다. 본 연구에서 다룰 연구문제를 정리하면 다음과 같다. 첫째, 인터넷 쇼핑몰에서 제품 구매시 제품유형과 인터넷 쇼핑몰의 명성 그리고 인터넷 쇼핑경험의 세 변수는 소비자의 지각된 위험에 각각 어떤 영향을 미치며, 탐색재와 경험재, 인터넷 쇼핑몰 명성의 정도 그리고 인터넷 쇼핑경험의 유무에 따라 어떤 차이점이 존재하는가\ulcorner 둘째, 소비자의 지각된 위험의 수준과 브랜드와 가격의 상대적 중요성 지각과는 어떤 관계가 있는가\ulcorner 셋째, 브랜드와 가격의 상대적 중요성 지각정도에 두 매개변수인 제품 정보량과 제품 친숙도가 어떤 역할을 하는가\ulcorner 등이다.bition of severity of convulsions, decrease of seizures threshold, decrease of audiogenic seizures in rats of different strains and normalization of cerebral blood flow (measured by hydrogen test) were demonstrated in rats after i.c.v., intraperitoneally and orally administration, respectively.

The primary purpose of this study is to identify the determinants of the users' satisfaction and commitment in personal media. For these purposes, we developed a research model based on the literature reviews of personal media, perceived risk and interactivity, satisfaction, and commitment. This study has identified four dimensions in the concept of perceived risk, such as privacy risk, social risk, time loss risk, and economic risk, and three dimensions in the concept of perceived interactivity, such as active control, two-way communication, and responsiveness. In survey, data were collected from 428 male and female who have an experience in personal media. Data was analyzed factor analysis, reliability analysis, measurement model analysis, and structural model analysis by utilizing SPSS 15.0 and AMOS 5.0 program. Analysis results of research model indicate the following. Firstly, privacy risk, active control, two-way communication, and responsiveness are significantly related satisfaction. Secondly, privacy risk, time loss risk, economic risk, active control, and two-way communication are significantly related commitment. Thirdly, users' satisfaction has positive relationship with commitment in personal media. Based on these results, theoretical implications for relevant researchers and managerial implications for personal media vitalization and marketing strategy are discussed. Finally, limitations for this study and further research issues are suggested.

This study empirically investigated the direct and indirect effects of inter-organizational relationships control mechanisms (IRCM; prudent partner selection and complex contract) on the decrease of inter-organizational risks (i.e., relational risk and performance risk). The empirical results showed that prudent partner selection has a positive impact on the degrees of inter-organizational cooperation and the levels of inter-organizational information flow. The effects of complex contract on the inter-organizational cooperation and information flow were not significant. In the results of the decrease of inter-organizational risks, it was observed that inter-organizational cooperation has significant positive effects on the decrease of both relational risk and performance risk. It was found that partner selection only influences the decrease of performance risk. The impact of inter-organizational information flow on the decrease of inter-organizational risks was not statistically significant. The indirect effects of IRCM on the decrease of performance risk through inter-organizational cooperation were also empirically demonstrated. The significant impact of inter-organizational cooperation on the decrease of risks implies that high levels of collaborations among employees decrease the risk of opportunistic behavior as well as the possibility of low degrees of performance through cooperative efforts. According to the results of the effects of risks on supply-chain performance, only the impact of performance risk was negatively significant. This result points out that the low levels of performance cause delays in delivery and product launch, deterred production and delayed market response, and these deteriorated managerial activities necessarily decrease the degrees of supply-chain performance.

Luxury products are sold in various online shopping malls in China. Companies utilize celebrities as their advertising models or disclose their CSR information to lower perceived risk. This study scrutinized the effects of CSR information and celebrity models on the relationship between perceived risk and the intention to use online shopping malls. According to the elaboration likelihood model, when consumers perceive high risk, they use the central route to process information and form attitudes. Celebrity models and CSR information as secondary clues may not have a significant effect. To test the hypotheses, a 2 (risk H/L)×2 (CSR)×2 (model) factorial design was employed. Study results found in a low perceived risk situation, CSR information or a celebrity model endorsing their products significantly increased the intention to use the shopping mall (model w/ 3.407 vs. w/o 2.88; CSR w/ 3.29 vs. w/o 2.779). However, in a perceived high-risk situation, their effects were not significant. Therefore, it is noteworthy that celebrity models and CSR information are effective in increasing the intention to use online shopping malls only when consumers use peripheral routes in a perceived low-risk situation.
