오늘날 도시지역은 인구밀집과 건축물의 고밀화로 인하여 자연재해나 인위적 재난이 발생할 경우 대형사고로 확산될 가능성이 매우 높다. 본 논문에서는 지형공간정보체계를 이용하여 도시지역의 종합적인 재해위험도를 평가하였으며, 이를 위해 도시지역 재해위험도를 침수위험도, 화재위험도, 건물붕괴위험도, 대피위험도 등 4가지로 세분하고 재해위험도를 평가하였다. 이러한 재해위험도 평가결과는 각종 도시관리계획을 수립할 때 재해를 최소화 시킬 수 있는 유효한 자료로 활용될 수 있다. 향 후 본 연구의 체계화와 전문성을 위하여 보다 많은 재해요소를 포함하고 관련분야의 전문가가 참여하는 공동연구 수행이 필요하다고 생각된다.

In human reliability analysis, dependence assessment is an important issue in risky large complex systems, such as operation of a nuclear power plant. Many existing methods depend on an expert's judgment, which contributes to the subjectivity and restrictions of results. Recently, a computational method, based on the Dempster-Shafer evidence theory and analytic hierarchy process, has been proposed to handle the dependence in human reliability analysis. The model can deal with uncertainty in an analyst's judgment and reduce the subjectivity in the evaluation process. However, the computation is heavy and complicated to some degree. The most important issue is that the existing method is in a positive aspect, which may cause an underestimation of the risk. In this study, a new evidential analytic hierarchy process dependence assessment methodology, based on the improvement of existing methods, has been proposed, which is expected to be easier and more effective.

The study is aimed to find out the factors which have influence on customers' satisfaction from information and prompt them to repurchase, based on the patterns of information seeking which vary according to categories of traditional eating out processed food. 500 housewives living in megalopolis whose age ranges from 20s to 50s are targeted to the research, and the self-report questionnaires were used. and also the analysis on the frequency, t-test, and multiple regression were taken. The summarized conclusion is as following: First, in terms of the patterns of information seeking, consumers, in general, are found more likely to be internal seekers, who seek information based upon their past experience, rather than to be external seekers. Second, the comparison of satisfaction after purchase of the groups categorized by the patterns of information seeking shows that, in terms of traditional eating out processed food, on the contrary to other products, the satisfaction of internal seekers is higher than that of external seekers. Third, in both groups of internal seekers and external seekers, purchase assessment and the evaluation of efforts for information seeking are found to have influence on the intention to repurchase in terms of information seeking, but the influence of used information evaluation is partial.

Purpose This study provided empirical support for the model that explain the formation of privacy concerns in the perspective of Information Boundary Theory. This study investigated an integrated model suggesting that privacy concerns are formed by the individual's disposition to value privacy, privacy awareness, awareness of privacy policy, and government legislation. The Information Boundary Theory suggests that the boundaries of information space dependends on the individual's personal characteristics and environmental factors of e-commerce. When receiving a request for personal information from e-commerce websites, an individual assesses the risk depending on the risk-control assessment, the perception of intrusion give rise to privacy concerns. Design/methodology/approach This study empirically tested the hypotheses with the data collected in a survey that included the items measuring the constructs in the model. The survey was aimed at university students. and a causal modeling statistical technique(PLS) is used for data analysis in this research. Findings The results of the survey indicated significant relationships among environmental factors of e-commerce websites, individual's personal privacy characteristics and privacy concerns. Both individual's awareness of institutional privacy assurance on e-commerce and the privacy characteristics affect the risk-control assessment towards information disclosure, which becomes an essential components of privacy concerns.

This study provides an in-depth comparison and analysis of various risk assessment models widely used in modern industries, and proposes the most suitable model for risk assessment of offshore wind power in Korea. The assessment models were selected by considering various factors such as the purpose of risk assessment, stakeholder requirements, and characteristics of offshore wind power. We also emphasized the importance of using different risk assessment models in combination in situations of high uncertainty. To systematize the combination of risk assessment models, we used systems engineering which is effective to develop a new system. Systems engineering was used to define the complete, traceable functions from site requirements, and model-based systems engineering was used to manage the design information from requirements to detailed functions in a single model. The developed risk assessment module provide automatic conversion between risk assessment models to enable risk assessment suitable for offshore wind power. The functionality and usability of the offshore wind risk assessment module were verified by the evaluation of three wind power experts.

This study focuses on the health risk assessment of airborne volatile organic compounds (VOCs) in a petrochemical complex, with several emphases on a risk assessment method. The first emphasis is on the importance of hazard identification to determine the likely carcinogenic potential of a VOC. Without considering this type of information, a direct comparison of the carcinogenic risks of two pollutants is meaningless. Therefore, wer suggest that this type of information be prepared and be listed with the estimate of cancer risk in parallel. The second emphasis is on the selection of a better dose-response model to estimate unit risk or cancer potency factor of a carcinogenic VOC. Finally, probilistic risk assessment method is discussed and recommended to use within a comparison of conventional point-estimate method. A health risk assessment has also been carried out. For non-carcinogenic risk, even the highest hazard index for carbon tetrachloride is estimated to be less than 1 with the other VOCs less than 0.03. However, the lifetime cancer risk from the inhalation of airborne VOCs is estimated to be about $2.6 \times 10^{-4}$ which is higher than the risk standard of $10^{-6}$ or even $10^{-5}$. Therefore, the investigation into domestic petrochemical complexes should be strengthened to obtain more fine long-term airborne VOC data.

Due to the increase of carbon dioxide and building regulations, BIM is considered a way of low-carbon and eco-friendly building development for its many advantages. The advantages can be maximized with Open BIM since it can produce optimal results for various purposes of energy performance assessment. However there are some problems in data interoperability in the process of Open-BIM based energy performance assessment. To solve such problems, this study focuses on space boundary information interoperability between IFC of Open BIM and IDF format of Energy Plus known as the most accurate and diverse energy performance assessment. The study analyzes the analogous study then figures out the problems of IFC based energy performance analysis, and suggests the way of interoperability. Finally, the development of automation program makes this way much more effective. The study of IFC data interoperability is useful for improving the reliability of Open-BIM based energy assessment.

토지적성평가는 공간계획에 있어서 실질적인 전략영향평가의 역할을 담당할 수 있으며, 2003년부터 국토계획법에 의하여 시행되고 있다. 토지적성평가는 토지의 물리적 사회적 공간적 특성에 따라서 개발사업의 시행 이전에 토지의 용도를 평가하는 과정이다. 토지의 특성을 파악하기 위해서는 지리정보를 기반으로 한 디지털 DB의 활용은 필수적이며, 법률상으로도 GIS를 활용하도록 규정하고 있다. 이 연구에서는 전라남도 지역의 교외지역을 대상으로 사례연구를 통하여 토지평가를 실시하고, 그 결과를 바탕으로 GIS의 측면에서 토지평가제도의 효율성과 실행성을 강화시킬 수 있는 방법론을 모색하였다.
