In this study, a quantitative risk assessment was carried out for a hydrogen complex station. The complex fueling station to be evaluated was hydrogen-LPG, and the components of each station were analyzed and the risk was evaluated. The final risk is assessed by individual and societal risks, taking into account the impact of damage and the frequency of accidents. As a result of individual risk calculation for the hydrogen-LPG fueling station that is the subject of this study, the hydrogen-LPG type fueling station does not show the unacceptable hazardous area (> 1 × 10E-3) proposed by HSE. The level of individual risk for both the public and the worker is within acceptable limits. In societal risk assessment, the model to be interpreted shows the distribution of risks in an acceptable range(ALARP, As Low As Reasonably Practicable). To ensure improved safety, we recommend regular inspections and checks for high-risk hydrogen reservoirs, dispensers, tube trailer leaks, and LPG vapor recovery lines.

For newly incoming technologies owing to the advancements in information and communications technology, the new form of information occurs due to the combination form of personal information. In turn, personal information which is combination with existing personal information is on the increase. It is difficult to equalize the method in order to analysis the degree of risk for personal information because it is qualitative method which is defined on the current Personal Information Protection Law. This dissertation presents the model to assess the degree of risk by using the IPA(Importance-Performance Analysis) after measuring the importance and the weighted value for the personal information based on the existing the method of risk assessment. Through the model suggested in this dissertation, the subjective judgement can be excluded, the combination of personal information can be assessed and the standard criteria which is used as the objective indicators from the quantitative degree of risk can be suggested.

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.

Along with the development of Internet services such as Social Network Service (SNS) and blog Service, the privacy is very important in these services. But personal data is not safety from exposure to internet service. If personal data is leak out, the privacy is disclosed to hacker or illegal person and the personal information can be used in a cyber crime as phishing attacks. Therefore, the model and method that protects to disclose privacy is requested in SNS and blog services. The model must evaluate degree of exposure to protect privacy and the method protects personal information from Internet services. This paper proposes a model to evaluate risk for privacy with property of personal data and exposure level of internet service such as bulletin board. Also, we show a method using degree of risk to evaluate with a proposed model at bulletin board.

예비 청년 창업농을 대상으로 개인적 특성을 파악하고 개인적특성, 사회적인식, 네트워크, 창농정책, 자기효능감, 주관적규범을 조사하여 창업의도에 영향을 주는 요인들을 파악하고자 하였다. 개인적 특성의 하위 변수로 성취욕구, 위험감수성, 혁신성을 설정하여 자기효능감, 주관적규범, 창업의도와의 관련성을 연구 하였다. 본 연구의 자료 수집을 위한 설문조사는 2018년 10월 2일부터 2018년 10월 27일까지 농업관련 창업교육 프로그램을 수강하였거나 농업분야에 관심이 있는 청년 농업 예비 창업자들에게 본 연구의 목적과 취지를 설명하고 연구의 동의를 얻어 설문지 300부를 배부하였다. 배부된 설문지 중 263부가 회수되었으며, 설문지 중 미응답이 한 문항이라도 있거나 불성실하게 응답한 설문지 15부를 제외한 248부를 최종분석 자료로 활용하였다. 본 연구의 결과는 다음과 같다. 청년 농업 예비창업자의 창업의도에 영향을 주는 요인으로 개인적 특성 중 위험감수성과 혁신성이 파악되었다. 또한 상관관계에서도 혁신성과 위험감수성은 상관관계가 높은 것으로 분석되었다. 그리고 환경적 요인인 사회적 인식, 네트워크와 창농정책은 모두 창업 의지에 영향을 주는 것으로 검증되었다.

This study aims to examine experiences of homeless risk factor before becoming the homeless focusing during their childhood period. This study underscore their victimization experience in their previous life with life history interviews of 60 homeless adults. As a result, this study identified various individual homeless risk factors they experienced for a long time. Also the risk factors were interactive, amplified and affect becoming homeless in the end. Moreover the results proved different characteristics between the group according how often they experienced homeless risk factors. These results show that the individual factors emerging homeless also start early stages of their life and those were invincible misfortune and victimization. These findings suggest that the government policy and proactive intervention in order to prevent homeless in the early stage need to be established and have more concerns about high risk youth.

소비자의 집단 구성원에 대한 자아지각은 소비자 의사결정에 어떠한 영향을 미칠까? 집단소비자 상호간에 영향을 미치는 의사결정 상황이나 소비자 개인적 의사결정상황 등 의사결정 상황에 따라 다르게 영향을 미칠까? 본 연구는 소비자가 집단의식을 인식할 때 개인적 차원과 집단적 차원에서 행해지는 의사결정이 어떻게 이루어지는지를 검증하고, 이때, 소비자의 위험회피성향에 따라 소비자 의사결정이 어떻게 조절되는가를 2 가지 실험을 통해 밝히고자 하였다. 미국 오레곤 주립대학교의 아시아계 학생들을 대상으로 2 가지 실험을 실시한 결과, 집단의식을 지각한 소비자는 집단관련 의사결정은 물론 개인관련 의사결정에서도 긍정적 영향을 미치는 것으로 나타났다. 그러나, 위험회피성향의 조절효과에 대한 실험결과는 집단의식을 지각한 소비자와 집단의식을 지각하지 않는 개인적 소비자 모두 처벌에 관한 상황에서 형평성 선호와 협상적 대안을 선택하는 것으로 나타나 집단의식지각의 의사결정에 대한 위험회피성향의 조절효과는 부분적으로 나타났다.

소방공무원은 가장 위험한 직업 중 하나이다. 하지만 기존의 논문들에서는 위험유발 요인에 대해 직접적인 사고원인으로서만 접근하는 경향이 있었으며, 그 분류에 있어서도 논리적이지 못하였다. 본고에서는 소방공무원을 둘러싼 위험 유발 요인들은 제도적 요인, 문화적 요인, 그리고 개인적 경험으로 분류하였다. 제도적 요인으로는 교육에 관한 부분과 작업환경에 관한 부분으로, 문화적 요인들은 성과지향적 문화와 배려지향적 문화로, 개인적 사고경험은 자신과 동료의 사고를 포함한 조직구성원의 사고경험과 기타 일반 희생자의 사고경험으로 나뉜다. 근무환경의 적정성과 관련해서는 특히 열악하게 인식하고 있었다.

This study performed a quantitative risk assessment for hydrogen-CNG complex refueling stations. Individual and societal risks were calculated by deriving accident scenarios that could occur at hydrogen and CNG refueling stations and by considering the frequency of accidents occurring for each scenario. As a result of the risk assessment, societal risk levels were within the acceptable range. However, individual risk has occurred outside the allowable range in some areas. To identify and manage risk components, high risk components were discovered through risk contribution analysis. High risks at the hydrogen-CNG complex refueling station were large leakage from CNG storage containers, compressors, and control panels. The sum of these risks contributed to approximately 88% of the overall risk of the fueling station. Therefore, periodic and intensive safety management should be performed for these high-risk elements.
