The quantitative evaluation method of the safety management cost was suggested to prevent a gas accident as a major industrial accident. In a gas governor station, process risk assessments such as the fault tree analysis(FTA) and the consequence analysis were performed. Based on process risk assessments, potential accident costs were estimated and the cost-benefit analysis(CBA) was performed. From the cost-benefit analysis for five classification items of safety management cost, the order of the cost/benefit ratio was estimated.

This research investigates the mechanism of ethical fashion consumption by examining the effects of benefit and risk perception on ethical fashion consumption attitudes and behavioral intention. To test the hypotheses, 300 female consumers between the ages of 20 and 49 were invited as study participants. The reliability and the validity of multi-item constructs were tested by Confirmatory Factor Analysis. The hypotheses were tested by utilizing Structural Equation Analysis and hierarchical multiple regression analysis. The benefit perception of ethical consumption was composed of three benefit types, which were altruistic benefit, social image benefit, and self-oriented benefit. Benefit perception, except social image benefit, had significant effects on consumer attitudes towards ethical fashion consumption; similarly, benefit perception had significant effects on behavioral intention (except self-oriented benefit) which had an effect on behavioral intention only when it was mediated by attitudes. Further analysis was conducted to understand the reason for the weak relationship between attitudes and behavioral intention. Financial and performance risk perceptions were tested for the moderating roles of attitudes and behavioral intention; subsequently, only financial risk interacted with attitudes and showed that the positive effects of attitudes on behavioral intention were weakened by a high financial risk perception. Performance risk had a main effect on behavioral intention independent of attitudes. Managerial implication and future study directions are also discussed.

Objectives: Balancing benefits and risks through the drug life cycle has been discussed for many decades. The objective of this study was to review the processes and tools currently proposed for benefit-risk assessment of medicinal drugs. It aimed to establish scientific and efficient drug safety management system based on the synthetic analysis of benefit-risk evidence. Methods: We conducted a review of exiting literatures published by regulatory agencies or initiatives. Not only quantitative methodologies but also qualitative method were compared to understand their key characteristics for the benefit and risk assessment of drugs. Results: Recently, benefit-risk assessments have more structured approaches to decision making as part of regulatory science. Regulatory agencies such as European Medicines Agency, FDA have prepared plans to apply benefit-risk assessment to regulatory decision making. Also many initiatives such as IMI (Innovative Medicine Initiative) have conducted research and published reports about benefit-risk assessment. For benefit-risk assessment, four kinds of methods are necessary. Frameworks such as BRAT (Benefit Risk Action Team) framework, PrOACT-URL provide guidance for the whole process of decision-making. Metrics are measurements of risk benefit. The estimation techniques are methods to synthesis and combine evidences from various sources. The utility survey techniques are necessary to explicit preferences of various outcome from stakeholders. Conclusion: There is the lack of widely accepted, validated model for benefit-risk assessment. Nor there is an agreement among academia, industry, and government on methods for the quantitative valuation. It is also limited by available evidence and underlying assumptions. Nevertheless, benefit-risk assessment is fundamental to improve transparency, consistency and predictability for decision making through the structured systematic approaches.

This study is to estimate differences, relationships and related factors of environmental risk perception and perceived benefit among residents and workers. A self-administered questionnaire survey using a structured instrument was carried out to residents and workers in industrial area during April, 2002. Total number of participants were 657 including 329 residents and 328 workers. Participants assessed environmental risk perception, self- assessed knowledge, trust in authorities and perceived benefit associated with 10 products manufactured in industrial area. There were difference in environmental risk perception, knowledge and trust in authorities and perceived benefit among residents and workers. Especially, trust in authorities and perceived benefit were statistically significant difference among residents and workers. Inverse relationships between environmental risk perception and perceived benefit have been observed for different products. In other words, the greater the perceived benefit, the lower the perceived risk, and vice versa. Factors mostly associated with participant's characteristics of environmental risk perception were age. marriage status (workers), education level (workers). There was statistically significant difference. Perceived benefit was statistically significant difference with sex, marriage status, residence duration, education level (workers). Related factors of environmental risk perception among residents and workers were age, trust in authorities. And factors affecting the perceived benefit were sex, age, education level (workers), and trust in authorities (workers). According to the results, people having high trust in the authorities perceived less risks than people having low in the authorities. To improve the communication of risk information, further study focus on assessment of experts, government and stakeholder in industrial area. Methodologies of this study can be used as the basis for investigating the structure of public perception of environmental products risks and benefit, designing a public information and risk communication program, and developing policy actions to improve acceptance.

The purpose of this study was to measure the effects of trust, knowledge, optimism, risk and benefits on consumer attitudes toward genetically modified foods. A total of 326 questionnaires were completed. Moderated regression analysis was used to measure the relationships among the variables. The analysis results for the data indicated a good model fit in Model 2 rather than Model 1, in which the direct effects of trust, optimism and benefits had statistically significant direct effects on the respondents' attitudes toward genetically modified foods, while the direct effects of knowledge and risk were not statistically significant. As expected, the interaction term of risk and benefit had a significant effect on consumer attitude. Moreover, the effect of risk on consumer's attitude toward genetically modified foods was statistically significant at all levels of benefit, except at the lower benefit level. Finally, the results of this study indicated that genetically modified food developers and marketers should attach importance to the interaction effect of benefits to understand the elements of market demand and customer loyalty.
