The purpose of this study is to investigate those factors that are influenced when a user recognizes his/her private information value as an economic asset. The relationship among these factors will also be discussed. This research targets Internet users, and the value of their private information will be converted into economic figures. How economic value changes in relation with individual attributes, dealer's traits, and circumstantial properties will also be studied. The changes in the factors of private information value under different situations will be analyzed from an economic perspective. By using the cost-benefit analysis framework, this work hypothesizes that the user's private information value can be influenced by individual attributes and situational properties. in the business aspect, this study can help users recognize the true value of their personal information and minimize the cost resulting from private information security incidents. This work also highlights the necessity of estimating the scale of investments for protecting private information. Overall, this research will proceed under the hypothesis that the users' recognition of their private information value is influenced by the attributes of the individual, dealers, or situations.

산업재해 통계분석의 커다란 목적은 각 산업별로 주 위험요인을 도출하고 이에 따른 안전교육의 실시 또는 안전장치 등을 보완함으로써 산업재해를 줄이거나 예방하는데 있다고 볼 수 있다. 그러나 일반 제조업이나 건설업 등에서는 아직까지도 정량적 위험성 평가 기법이 개발되어 있지 않은 실정이다. 따라서 효율적인 위험성 평가 기법의 개발이 필요하다. 본 연구에서는 데이터마이닝 기법을 이용한 산업재해 예방을 위한 최적 알고리즘 선정 방법을 제시한다.

본 연구는 IT아웃소싱 서비스 공급기업의 관계 성과를 조명하기 위하여 성과를 사회적 기술적 측면으로 접근하고 이에 대한 영향 요인으로 파트너십 형성 요인과 파트너십을 성장 강화시키는 요인에 대한 다중회귀분석을 실시하였다. 성공적인 아웃소싱은 서비스 고객사와 서비스 공급사간의 지속적인 의사소통은 물론 상호간 위험과 이익을 공유하며 필요시 서로 상생할 수 있는 파트너십 관계로의 관리가 요구되고 있음을 탐색하고자 하였다.

Risk analysis model is systematic and structural process that considers internal security problems and threat factors of the information systems to find optimal level of security control. But, the risk analysis model is just only defined conceptually and there are not so many empirical studies. This research used structural equation modeling(SEM) research methodology with rigorously validated research instrument. Based on results of this study, risk analysis methodology was proved to be practically useful in e-commerce environment. Factors like threat and control were significantly related to risk. In conclusion, the results of this study can be applied to general situation or environment of information security for analyzing and managing the risk and providing new approach to comprehend concept of risk in e-commerce environment.

This study aims to discuss the role and function of social capital in explaining social risk perception among female-headed households. This study analyzed the level of social risk perception and its determinant factors of female-headed households using 2020 Social Survey data from Statistics Korea. The analysis revealed that socio-demographic factors and social capital influenced the perception of social risk. In addition, the social capital related to social safety was associated with the level of social risk perception. Even after controlling for various factors, the social risk perception level among female-headed households was higher than among male-headed ones. Among female-headed households, social capital such as compliance with regulations or ability to cope with risk; demographic factors such as age, residential area, and health status; and economic factors such as income level and housing type were found to affect social risk perception. Based upon the findings this study devises ways to accumulate social capital that can be obtained in cooperative relationships between families and communities.

소비자들이 제품을 구매할 때 갖는 위험 지각(perceptions of risk)은 인터넷을 통한 상거래의 확산에 있어서 큰 걸림돌이다. 즉, 소비자들은 구매전에 제품을 직접 만져보거나 시용해 보지 못하기 때문에 여러 가지 종류의 위험 부담을 안고 구매를 할 수밖에 없는 것이다. 본 연구는 소비자들이 인터넷 쇼핑을 할 때에 느끼는 이러한 여러 가지 위험 요소들을 실증 자료를 통하여 보다 구체적으로 살펴본 것이다. 특히 이 실증 연구에서는 이러한 요소들을 찾아내어 분류하였고, 이러한 위험 요소들이 인터넷 쇼핑몰에 대한 이용 의도에 미치는 상대적 영향력을 측정하였다. 또한 본 연구는 이러한 위험 지각 수준을 감소시킬 수 있는 쇼핑몰 평가 요인들에 주목하여, 이들의 위험 지각 요인들에 대한 영향력도 살펴보았다. 끝으로 본 연구가 인터넷 마케터들에 대하여 가지는 전략적 시사점을 논한다.

This paper examines the time-series relations among expected return, risk, and book-to-market(B/M) at the portfolio level. The time-series analysis is a natural alternative to cross-sectional regressions. An alternative feature of the time-series regressions is that they focus on changes in expected returns, not on average returns. Using the time-series analysis, we can directly test whether the three-factor model explains time-varying expected returns better than the characteristic-based model. These results should help distinguish between the risk and mispricing stories. We find that B/M is strongly associated with changes in risk, as measured by the Fama and French(1993) three-factor model. After controlling for changes in risk, B/M contains little additional information about expected returns. The evidence suggests that the three-factor model explains time-varying expected returns better than the characteristic-based model.

본 연구에서는 가상시장에서 인터넷쇼핑몰을 통해 제품을 구매한 경험이 있는 소비자의 재구매의도를 확인하고자 시도하였다. 인터넷쇼핑몰을 통해 제품을 재구매하기 위해서는 이전 구매경험의 만족이 결정적 요인으로 작용할 것으로 가정하였다. 이러한 쇼핑만족에 영향을 주는 요인으로는 쇼핑몰의 구조적 특성(심미성, 이용편리성), 제품특성(품질, 가격), 그리고 서비스 특성(확신성, 신뢰성, 반응성) 등을 포함하였다. 이들 요인이 쇼핑만족에 영향을 주고, 만족이 재구매의도에 영향을 줄 것으로 가정하였다. 또한, 이들 만족과 재구매의도간의 관계는 지각된 위험 및 제품관여에 따라 조절역할을 할 것으로 가정하였다. 이러한 가설들간의 관계를 분석하고자 구조방정식모델을 실시하였고, 조절변인들의 조절효과는 조절회귀분석을 통해 검증하였다. 분석결과, 모든 연구가설들은 유의적으로 나타났다. 즉 쇼핑몰의 구조적 특성, 제품특성 및 서비스 특성은 쇼핑만족에 영향을 주며, 이러한 쇼핑만족은 소비자의 재구매의도에 영향을 주는 것으로 나타났다. 또한 만족과 재구매의도간의 관계는 지각된 위험과 관여수준에 따라 조절역할을 하는 것으로 나타났다

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.
