The objective of this paper is to provide an improved reorder decision policy for general multi-echelon distribution systems utilizing the shared stock information. Since it has been known that traditional reorder policies sometimes show poor performance in distribution systems, in our previous research we introduced the order risk policy which utilizes the shared stock information more accurately f3r the 2-echelon distribution system and proved the optimality. However, since the real world supply chain is generally composed with more than 2 echelons, we extend the order risk policy for the general multi-echelon systems. Since the calculation of the exact order risk value fur general multi-echelon systems is very complex, we provide two approximation methods. Through the computational experiment comparing the order risk policy with the existing policies under various conditions, we show the performance of the order risk policy and analyze the value of the shared stock information varying with the characteristics of the supply chain.

This paper is a comparative study on risk assessment policy between Asian countries such as Japan, Korea, Singapore and EU countries, German, UK. Risk assessment is a tool adopted currently in many countries in order to reduce occupational risk in workplace because it help employers to identify their hazard arousing in their working conditions then to settle the issues. This paper compares institutional framework posed in EU and Asian countries. As a result of comparative study, EU countries have more concrete legal system for risk assessment than Asian countries. But Asian countries are now interested in risk assessment such as Japan, Korea and Singapore. The author also suggests successful ways to settle down the risk assessment policy in a country. These findings help to understand occupational health and safety policy on risk assessment in Asian countries.

Objectives: The purpose of this study was to identify the factors which affect risk perception and attitude on government risk management over medications containing asbestos among parents of elementary school students. Methods: This research design was cross-sectional study using self-administered questionnaire. The survey subjects were parents of elementary school students in Seoul, total of 1,051 subjects. The survey period was from June through July of 2011. The collected data were analyzed using the SPSS 20.0. Results: The subjects perceived high risk regarding medications containing asbestos. About 83.6% of the subjects perceived that the result taking of medications containing asbestos was fatal, 82.8% felt that medications containing asbestos was a very serious social problem, 79.5% agreed that medications containing asbestos was a new type of threat. The risk perception for medications containing asbestos was related to political affiliation, attitudes of dealing medicines, main use of media, and personal communication credibility. Those who did not believe that the current government policy was correct and the government was working toward the public's benefit and not its own had the higher level of negative attitudes towards the government's risk management over the case of medications containing asbestos. Conclusion: In implementing government policy, all information should be efficiently and accurately communicated through a transparent implementation process. Also, the government must have plans for countermeasures in case of an emergency and respond efficiently in order to maintain their credibility. Moreover, this highlights the need for health authorities to exert more effort in increasing public education/awareness, especially those concerning drug and dug-taking behavior, in order to harness positive attitude and trust towards the government's policy. For a more effective risk communication, the media, health experts, government representatives, and related industries should work together.

Due to the improvement of modern information technologies, sharing stock information among the supply chain members is a common practice nowadays. Many companies are planning to adopt the information systems to possess the real-time shared stock information. Thus, it is needed to quantify the value of shared stock information. The purpose of this paper is to evaluate the value of the shared stock information for two-echelon distribution systems. Existing reorder policies can be classified into installation stock policies and echelon stock policies. Since installation stock policies do not utilize the shared stock information, and both classes of policies may show poor performances for distribution systems, we cannot evaluate the value of the shared stock information with the existing policies. Thus, we provide a new type of reorder policy, named order risk policy. We define the order risk using marginal analysis, and prove the optimality. Through computational experiment that compares the order risk policy with the existing policies, it is shown that a significant cost reduction is achieved with the effective utilization of the shared stock information. We also show the effect of the system characteristics on the value of the shared stock information.

As the features of recent flood are spatially concentrated, loss of life and property increase by the impact of climate change. In addition to this the public interest in water control information is increased and socially reasonable justification of water control policy is needed. It is necessary to estimate the flood risk in order to let people know the status of flood control and establish flood control policy. For accurate flood risk analysis, we should consider inter-relation between causal factors of flood damage. Hence, flood risk analysis should be applied to interdependence of the factors selected. The Bayesian networks are ideally suited to assist decision-making in situations where there is uncertainty in the data and where the variables are highly interlinked. In this research, to provide more proper water control information the flood risk analysis is performed using the Bayesian networks to handle uncertainty and dependency among 13 specific proxy variables.

In order to deal with uncertainty and conflicting interests in technological risk policy-making, various participatory decision-making models have been practiced. This participatory approach is an alterative to the traditional process of science and technology policy-making where scientific experts provide evidence and government officials make decisions. However, there still remain different opinions on who should play what kind of role in decision-making process. Therefore this paper examines the division of labour in the public deliberations for radioactive waste management policy carried out in the UK and Korea. It discusses the ways in which various actors are defined, and the rationales are employed for allocating actors to certain roles and participatory methods. In so doing, this paper unfolds the ways in which the participatory decision-making process for risk governance is delivered in real policy context. Similarities and differences revealed in the division of labour of two cases contribute to development of radioactive waste management policy and the policy instruments for risk governance.

Air pollution in large cities is reduced through the environmental health policies, but due to increased population and automobile, some pollutants are still a problem. These air pollutants are known to cause asthma and respiratory diseases. According to an OECD report, the number of premature deaths will increase. Hazardous air pollutants should be managed through a systematic monitoring, risk assessment, and many studies are in progress. In order to manage hazardous air pollutants, transformation of policy for the protection of human health is required. management policy through the calculation of the excess number of deaths that occur from hazardous air pollutants for the public health is necessary. Korea has put a lot of efforts for air quality, but health risk assessment should be more considered.
