  • Many studies in risk management have been focused on management process, contract relation, and risk analysis in the past decade, but very few studies have addressed project risks from the perspective of risk efficiency. This study started with using Fault Tree Analysis to develop a framework for the decision-making support system of risk management from the perspective of risk efficiency, in order for the support system to find risk strategies of optimal combination for the project manager by the trade-off between project risk and cost of project strategies. Comprehensive and realistic risk strategies must strive for optimal decisions that minimize project risks and risk strategies cost while addressing important data such as risk causes, risk probability, risk impact and risk strategies cost. The risk management in the construction phase of building projects in Taiwan upon important data has been analyzed, that provided the data for support system to include 247 risk causes. Then, 17 risk causes were extracted to demonstrates the decision-making support system of risk management from the perspective of risk efficiency in building project of Taiwan which could reach better combination type of risk strategies for the project manager by the trade-off between risk cost and project risk.

  • Food borne pathogens are a growing concern for human health and food safety throughout the world. Milk and dairy products are commonly associated with spoilage or contamination from a wide variety of physical, microbial, and chemical hazardous. Microbiological risk analysis consists of three components: risk assessment, risk management, and risk communication, and overall objective of this process is ultimately public health protection. The microbiological risk assessment is useful tool to evaluate food safety as it is based on a scientific approach. In addition risk assessment process includes quantitative estimation of the probability of occurrence of microbial hazards to evaluate more accurate human exposure. The aim of this study is to review the microbiological risk assessment on the prevalence of bacterial foodborne pathogens in milk and dairy products.

  • This study developed a risk society education program for undergraduate students to help them understand the epistemological uncertainty of risk caused by COVID-19. And it was applied to science-related classes of undergraduate students, and the purpose was to examine the degree of understanding and thoughts of undergraduate students about the risk society through science writing. As a result, it was found that the degree of understanding of the risk society was very high in all participating students regardless of their majors in science, engineering, humanities and social sciences. In addition, it was analyzed that the risk society education program helped undergraduate students to resolve the epistemological uncertainty of the risk of COVID-19 and to have an attitude to overcome the the difficult mind due to the COVID-19 distancing. The results of this study suggest that risk society education is necessary for future generations living in an era of risk of climate change and pandemic that exceeds the prediction range of science and technology in science education.

  • This paper tries the systematic approach to risk which is a major theme in engineering ethics utilizing science and technology studies. The types of risk can be classified as technical risk, methodological risk, epistemological risk by the degree of uncertainty. The strategies for risk management can be assorted to applied science strategy, professional consultancy strategy, post-normal science strategy. These types and strategies of risk request different kinds of expertise such as technocratic expertise, interactive expertise, democratic expertise. This paper can not only contribute to complement and extend engineering ethics education but also be linked with the goals of engineering education in general.

  • Acceptable risk problem are decision problems they requires a choice among different estimations of technological risks. The alternative option includes a threat to life among its consequences. However, the definition used to ignore the public's perceived risk which should be identified as acceptable risk. The study examine the role of perception of risk as acceptable risk between different situations of estimated consequence and probability of risk. The cost benefit principle for the reduction of risk applied to find the possible solutions with in decision making process.

  • The purpose of this study is to find the perceived risk which influences consumers' purchase attitudes so that consumers' participation in electronic commerce could be enhanced. Consumer behavior involves risk in the sense that any action of a consumer will produce consequences which one cannot anticipate, and some of which are at least likely to be unpleasant. The types of perceived risks are financial risk, performance risk, social risk, psychological risk, time loss, opportunity loss, privacy risk, fashion loss, delivery risk, seller's response risk and seller's fraud risk The findings are as follows: $\circled1$ The financial risk, performance risk, time loss, delivery risk, seller's response risk and seller's fraud risk have negative effects on the consumers' purchase attitudes. $\circled2$ There is no difference in the level of perceived risk according to the demographic factors such as age, education and income level.

  • In order to assess risk of high temperature damages about corn during reproduction stages in the future, we carried out analysis of climate change scenarios RCP (Representative Concentration Pathway) 4.5 and RCP8.5 distributed by KMA (Korea Meteorological Administration) in 2012. We established two indexes such as average of annual risk days of high temperature damage which express frequency and strengthen index of high temperature damage. As results of producing maps for 157 cities and counties about average of annual risk days of high temperature damage during total periods of scenarios, the risk of high temperature in RCP8.5 was evaluated to increase at all over nation except inland area of Gangwon province, while RCP4.5 showed similar to present, or little higher. The maps of annual risk days of high temperature damage with 10 years interval in RCP8.5 prospected that the risk for damaging corn growth would increase rapidly from 2030's. The largest risk of high temperature damage in the future of RCP8.5 was analyzed at Changnyeong county located east-south inland area in Kyeongnam province, while the smallest of risk counties were Pyeongchang, Taebaek, Inje, and Jeongseon. The prospect at 12 counties which is large to produce corn at present and contains large plains have been showed that there will be only a little increase of risk of high temperature at Goesan, Yangpyeong, Hongcheon, Seosan, and Mooju until 2060's. But considering strengthen index of high temperature damage, most regions analyzed would be prospected to increase rapidly after 2030's. To cope with high temperature damage of corn in the future, we should develop various practical technologies including breeding adapted varieties and controlling cultivation periods.

  • Caseous lymphadenitis (CLA) is an endemic but not well-studied disease of Korean native goats (KNG) in Korea. Corynebacterium pseudotuberculosis is the causative agent of the contagious and chronic CLA found in goats. This study aimed to validate the potential risk factors associated with CLA and assess its seasonal prevalence to mitigate this disease in KNG. Data were collected through a questionnaire from four high- and four low-prevalence farms randomly selected based on a prior investigation. The monthly assessments of CLA were conducted in a goat abattoir located in Jeonnam Province, Korea, to evaluate its seasonal prevalence. The associated risk factors for CLA in KNG herds imply that herd size, scratching against pillars, pipes, or walls in the herd, and disinfection of goat herds are potential risk factors for CLA (P<0.05). The type of floor and entry of new goats into the herd, which are potential risk factors, affected CLA prevalence in the KNG herd (P<0.2). The prevalence of CLA in KNG was significantly higher in spring (29.34%) than in autumn (14.61%), summer (15.31%), and winter (19.48%) (P<0.05). Based on the risk factor assessment, attention should be to establishing accurate preventive measures by avoiding these identified potential risk factors.
