Regester & Larkin(2005) suggest the issue and risk lifecycle analysis method in risk management, made up of the potential, emerging, current, crisis, and dormant stages. Investment on New & Renewable Energy is meaningful in effect ive risk management for diminishing or reducing the shock of a energy current, at the potential stage. In this study, we survey the risk of traditional fossil fuel projects and develop the risk analysis model for new & renewable energy projects specially geothermal energy resources and gas-hydrate resources.

A new technology has provided the nation, industry, society, and people with innovative and useful functions. National economy and society has been improved through this technology innovation. Despite the benefit of technology innovation, however, since technology society was sufficiently mature, the unintended side effect and negative impact of new technology on society and human beings has been highlighted. Thus, it is important to investigate a risk of new technology for the future society. Recently, the risks of the new technology are being suggested through a large amount of social data such as news articles and report contents. These data can be used as effective sources for quantitatively and systematically forecasting social risks of new technology. In this respect, this paper aims to propose a data-driven process for forecasting and assessing social risks of future new technology using the text mining, 4M(Man, Machine, Media, and Management) framework, and analytic hierarchy process (AHP). First, social risk factors are forecasted based on social risk keywords extracted by the text mining of documents containing social risk information of new technology. Second, the social risk keywords are classified into the 4M causes to identify the degree of risk causes. Finally, the AHP is applied to assess impact of social risk factors and 4M causes based on social risk keywords. The proposed approach is helpful for technology engineers, safety managers, and policy makers to consider social risks of new technology and their impact.

This research designed and implemented a supply chain risk management platform and applied it to a case study of reduced-fat Lanna pork sausage as a new product development project. The proposed framework has three stages: risk identification, risk assessment, and risk mitigation. Seventeen risk agents with 17 risk events were identified based on SWOT analysis and the Porter Five Forces concept through the process of planning, sourcing, making and delivering, partially captured from the supply chain operations reference model in the first stage. In the second stage, an house of risk (HOR) framework was applied to present the impacts of each risk agent. In the third stage, eight risk agents with high impact were selected to design 21 preventive actions. Finally, three preventive actions with the highest effectiveness to difficulty ratio scores-'sales evaluation of familiar products', 'increasing distribution channels and promotions to improve sales', and 'work flow improvement for work safety'-were then recommended for this new product development.

This study identified problems of the existing ecosystem-based fisheries assessment approach, and suggested new methods for scoring risk and for the estimation of fishery risk index. First, risk scores of zero to two for target and limit reference points for each indicator were replaced by those of zero to three, and the risk scores were calculated from new formulae which were developed in this study. Second, a new method for estimating fishery risk index (FRI) was developed in this study, considering the level of indicators. New method was applied to the Korean large purse seine fishery, large pair trawl fishery and drag net fishery. More precise and detailed risk scores were obtained from the new method, which can explain the risks by the wider range of both risk levels for 'better than target' and 'beyond limit'. The new method for estimating FRI could avoid the basic problem related with duplicated computations of fishery-level indicators, which improved the estimated FRI to be more accurate. Also, a method for estimating variance of FRI using the bootstrap was proposed in this study.

본 연구는 보강된 기존사면에 대한 새로운 사면 위험도 평가방법에 대한 연구로서 기존의 사면 안정성 및 위험도 평가방법들에서 주요 위험도 영향요소로 구분되는 강우, 암종, 배수상태 항목들에 대하여 검토하고 분석하였다. 분석 결과 사면 위험도에 영향을 미치는 19개의 주요요소를 선정하였으며 이를 Hudson(1991)이 제안한 Interaction matrix 개념의 위험도 분석 모델에 적용하였다. 적용결과 기존사면 위험도 평가방법인 SRI(Slope Risk Index)를 제시하였으며 국내 15개소 사면을 대상으로 검증을 실시하였다. 검증 결과 제시한 기존보강사면의 위험도 평가방법의 신뢰성을 확인할 수 있었다.

This paper presents a new approach to risk comparison in uncertain environment. Based on the uncertainty theory, some uncertain risk measures and risk comparison rules are proposed. Afterward the bridges are built between uncertain risk measures and risk comparison rules. Finally, several comparable examples are given.

The purpose of this study was to identify the new fashion brand evaluation attributes influenced by risk perception and its relationship with information search. As for the method of the research, questionnaires were given to 311 consumers who just finished shopping at new fashion brand stores. The results of this study were as follows: 1) New fashion brand evaluation attributes consisted of five factors; product experience attributes, celebrity credence attributes, product search attributes, brand credence attributes, salesperson search attributes. 2) New fashion brand evaluation attributes were found to be significantly influenced by risk perception. 3) The amount of information seeking and the use of information sources were found to be significantly related to the new fashion brand evaluation attributes. 4) The variables influencing on the new fashion brand evaluation attributes were age and monthly clothing expenses.

This paper describes the analysis technique of risk voltage around grounding electrode by new touch and step voltage measurement methods. We have analyzed three techniques for risk voltage measurement, such as footprint-electrode method, test-probe method, and simulated-personnel method. We have selected test-probe method considering applicability of site. In order to reduce error related to the location of the auxiliary electrode, we propose a new approach to perform risk voltage measurement with minimum errors and short auxiliary electrode distances. Field tests were carried out at a grounding grid. It can be concluded that the proposed method will be satisfactory for risk voltage measurement.

본 연구의 목적은 R&D성과를 높이기 위해 신제품개발프로세스 단계별로 연구 개발을 수행하면서 고려되어져야 할 위험요인을 식별하고, 위험요인의 영향을 분석하기 위한 것이다. 이를 위하여 본 논문은 대한민국의 대표 IT 기업인 삼성 및 LG전자의 계열사가 최근 5년 이내 개발한 IT 신제품에 대한 설문조사를 기반으로 하였다. 연구는 우선적으로 신제품개발프로세스에 따라서 위험요인을 식별하였고, 설문지를 통해 식별된 위험요인을 평가하였다. 위험의 영향을 분석하기 위해 R&D 성과를 기반으로 로지스틱 회귀분석을 실시하였다. 위험요인의 영향은 저 성과 그룹에서 높게 나타남을 알 수 있었다. 고 성과 그룹은 R&D 성과를 높이기 위해 프로젝트를 관리하는데 있어서 위험을 중요한 일로 간주하고 있었으며, 효과적으로 위험요인을 잘 관리하였다. 결론적으로 R&D 성과를 높이기 위해 신제품개발프로세스 단계별로 위험요인을 식별하고 분석한 후, 영향력이 큰 위험을 집중적으로 관리하는 위험관리활동이 필요함을 알 수 있었다.

Since the last 50 years, the terminology 'risk' has been widely used in general and industrial applications, with different meanings. The different definitions of risk can lead to the different risk assessments and risk management process elements, and the misunderstandings. For the reasons, the ISO(International Standard Organization) has recently defined a new risk concept through the publication of IS0 31000:2009. Although the new concept of risk was globally accepted, it seem to be argued in its definition debate. Thus, this paper reviews the definition and meaning of the concept of risk in terms of risk origin, general and industrial applications, related domestic laws and risk management standards published to improve an understanding of risk concept.
