The present study began from the criticism that the discussions related to the existing digital media have focused on the technical productivity and effectiveness to focus on the positive perspective. Therefore, this study will concretely confirm the dangers that may be caused by digital media and confirm the overall risk perception for digital media such as the user's opinions for risk evaluations and risk management for such dangers. As a result of making the digital convergence media, the smart phone, as the detail study subject, the 17 risk types including the 'risks of financial dimensions, risks of social-cultural dimensions, risks of individual dimensions and risks of pathological dimensions' were classified. Furthermore, the users appeared to highly evaluate the seriousness and possibilities of risks as a result of analyzing the risk-factor per each risk type(risk magnitude ${\times}$ development possibility). Next, it appeared that the users did not have high degree of reliability for the government in the aspects of countermeasures and prevention of risks and appeared to highly evaluate their expectation and liability for their individual roles. If the seriousness and development possibilities, the evaluations for liability, preventative measures and post-management methods for the risks of smart phones can be thoroughly analyzed and applied, it will be able to expand them as significant political countermeasures that can reduce the risks of other digital media in the future.

Recently, personal information leakage has caused phishing and spam. Previously developed systems focus on preventing personal information leakage. Therefore, there is a problem that the leakage of personal information can not be discriminated if there is already leaked personal information. In this paper, we propose a personal information hazard classification system based on web document analysis that calculates the hazard. The system collects web documents from the Twitter server and checks whether there are any user-entered search terms in the web documents. And we calculate the hazard classification weighting of the personal information leaked in the web documents and confirm the authority of the Twitter account that distributed the personal information. Based on this, the hazard can be derived and the user can be informed of the leakage of personal information of the web document.

The object of this study is to develop a tool for quantifying risks related to the rail transportation of hazardous commodities and to present mitigation measures. In this study, the Quantitative Risk Assessment (QRA) is used as a risk analysis tool. Based on the previous explosion history (Iri explosion) and consideration of its high risk, Iksan-si is selected as a model city. The result, expressed as average individual risk for exposed people with various distance, indicates that the model city is considered to be safe according to the nuclear energy standard. Also, the mitigation measures are provided since Societal risk of Iksan-si is set within ALARP. Risk reduction measures include rail car design, rail transportation operation, demage spread control as well as derail prevention and alternative routes for reducing accident frequencies. Finally, it is expected to achieve high level of public safety by appling the risk reduction measures.

In this study, we examined the influence of news frame and involvement on risk perception. Based on individuals' optimistic bias in risk judgement and the third-person effect theory, we developed research hypotheses. An experiment was conducted in which 243 undergraduate and graduate students participated. Results indicated that societal level risk judgements were relatively invariant across experimental conditions but personal level risk judgements were influenced by the news frame and individuals' involvement in irradiated food. Based on the results, we provide explanations concerning when and how optimistic bias takes place in each experimental condition.

This study built the theoretical frameworks for empirical analysis based on the analysis of the relationship among the concepts of risk of information privacy, the policy of information privacy via the provision studies. Also, in order to analyze the relationship among the factors such as the concern of information privacy, trust, intention to offer the personal information, this study investigated the concepts of information privacy and studies related with the privacy, and established a research model about the information privacy. Followings are the results of this study: First, the information privacy risk has the positive effects upon the information privacy concern and it has the negative effects upon the trust. Second, the information privacy policy has the positive effects upon the information privacy concern and it has the negative effects upon the trust. Third, the information privacy concern has the negative effects upon the trust. At last, the information privacy concern has the negative effects upon the provision intention of personal information and the trust has positive effects upon the offering intention of personal information.

Although many studies have focused on the influences and outcomes of personal information leakage, few studies have investigated how the personal information leakage prevention behavior differs depending on internet user. This study attempts to supplement the existing studies' limitations with the use of risk perception attitude (RPA) framework. More specifically, this study tries to show internet user can be classified into four groups based on perceived risk of personal information leakage and efficacy beliefs of personal information protection, and to identify how the groups differ in terms of motivation, information seeking, and behaviors for privacy leakage prevention. Analysis on survey data from 276 internet users reveals that the users can be classified into responsive, avoidance, proactive, indifference groups. Furthermore, there are differences between groups in terms of motivation, information seeking, and behaviors for personal information leakage prevention. This study contributes to expand existing literature by providing tailored guidelines for implementation of personal information protection strategies and policy.

The current study investigates VPA usage (i.e.,continuance intention of use, WOM intention) of by Theory of Planned Behavior (i.e.,attitude toward to VPA, subjective norm, perceived behavioral control) and perceived value/risk. The results show that (1) attitude toward to VPA, subjective norm, perceived behavioral control, and perceived value positively predicted the continuance intention of VPA use. Regarding WOM of intention, there were positively significant effects of the attitude toward to VPA, subjective norm, perceived behavioral control, and perceived value. The results of this study are expected to provide a variety of practical and theoretical implications in promising artificial intelligence market by the impact of TPB (i.e.,attitude toward to VPA, subjective norm, perceived behavioral control) and perceived values of VPA.

주식시장에서 환율위험프리미엄의 존재유무는 기업의 투자 및 자본조달, 외환헤징재무활동, 개인의 투자전략 등에 중요한 영향을 미치게 된다. 본 연구에서는 차익거래모형을 이용하여 우리나라 주식시장에서 환율위험노출을 측정하고, 그 환율위험이 시장에서 보상되는 위험인가를 검정한다. 전체 표본기간은 1980년부터 1998년까지이며, 외환자유화와 자본시장 개방이 본격적으로 이루어진 1992년 이전과 이후를 하위기간으로 구분하여 분석하였다. 표본하위기간의 설정, 다각적인 환율위험요인 측정, 다양한 모형설정과 복수의 통계추정방법의 적용 등을 통하여 환율위험 프리미엄의 유무에 관련된 신뢰성있는 결론을 도출하고자 하였다. 1980년대 표본전기 하위기간에는 주식시장에서 통계적으로 유의한 환율위험노출을 확인하기 어려웠으나, 외환자유화와 자산시장개방이 본격화된 표본 후기 하위기간에는 뚜렷한 환율위험 의 존재를 확인할 수 있었다. 후기 하위기간을 대상으로 시장위험과 실효환율위험만을 포함한 차익거래모형을 적용하였을 때에 통계적으로 유의한 환율위험 프리미엄이 확인되었다. 그러나 달러환율과 엔화환율위험을 별개의 환율위험으로 설정한 경우 각 환율위험에 개별적으로나 결합적으로 통계적으로 유의한 위험프리미엄을 발견하지 못하였다. 더구나, 실효환율위험에 추가하여 산업생산위험, 인플레이션위험, 기업부도위험 등의 기본적 경제요인 위험을 함께 통제변수로서 포함하여 차익거래모형을 적용하였을 때에도 환율위험 프리미엄은 존재하지 않았다.
