Risk assessment defines as the process of estimating both the probability that an event will occur and the probable magnitude of its adverse effects. Chemical or microbial risk assessment generally follows four basic steps, that is, hazard identification, exposure assessment, dose-response assessment, and risk characterization. Risk assessment provides an effective framework for determining the relative urgency of problems and the allocation of resources to reduce risks. Using the results of risk analyses, we can target prevention, reme-diation, or control effects towards areas, sources, or situations in which the greatest risk reductions can be achieved with resources available. Risk assessment is also used to explain chemical and microbial risks as well as ecosystem impacts. Moreover, this process, which allows the quantitation and comparison of diverse risks, lets risk managers utilize the maximum amount of complex information in the decision-making process. This information can also be used to weigh the cost and benefits of control options and to develop standards or treatment options.

The purpose of this study is to compare and analyze the process of hospital visits according to the characteristics of the elderly visiting to emergency medical centers. The subject of study was 571 patients over the age of 65 who agreed to participate in the study of emergency medical centers from May 1 to 31, 2010. The frequency, percentage and ${\chi}^2$ test of collected data were conducted with SPSS WIN 12.0. As a result, the frequency of the aged with or without urgency revisiting emergency rooms due to chronic degenerative diseases was high. In addition, there were many cases that the aged living only with a spouse or remaining single. It was obscure to classify them into a urgent or non-emergent group which made it longer time to visit a hospital. It may be necessary that the care for urgent elderly patients considering the characteristics of the family environment functions to care the elderly were weakened.

This study presents the Analytical Hierarchy Process (AHP) as a potential decision-making method for obtaining the relative weights of alternatives through pairwise comparison in the context of hierarchical structure. The aim of this study was to elicit prior strategies for brand communication for Korean restaurants overseas. We created a questionnaire and surveyed experts at government agencies, restaurant companies, and universities from October to November 2011. By applying the pairwise comparison matrix, relevance was perceived as a more important strategy evaluation criteria than effectiveness or urgency. The highest-ranked strategy was the 'Identification of the BI and positioning of Korean restaurants' followed by 'Development of Korean food content for overseas promotion', 'Development of locally customized Korean food recipes and new Korean menus', 'Development of marketing communication strategies for Korean restaurants by countries', and 'Development of Korean restaurant differentiation strategies'. The results of this study can be used for effective Korean food globalization by enhancing the competitiveness in the world market.

Korea successfully achieved energy independence in the shortest period of time from being the poorest country in terms of energy 50 years ago through steady development of nuclear technology. In the past, the nuclear industry has been driven through government-centered policy development, public institution-based research, and industrial facility and infrastructure construction. Consequently, South Korea became a nuclear energy powerhouse exporting nuclear power plants to the UAE, surpassing the level of domestic technological independence. However, in recent years, the nuclear industry in Korea has experienced a decline in new plant construction since the Fukushima accident in Japan, which caused changes in public perspectives regarding nuclear power plant operation, more stringent safety standards on the operation of nuclear power plants, and a shift in governmental energy policy. These changes are expected to change the domestic nuclear industry ecosystem. Therefore, in this study, we investigate the priority of technology development investment from the perspective of experts in private nuclear power companies, shifting the focus from government-led nuclear R&D policies. To establish a direction in nuclear technology development, a survey was conducted by applying an analytic hierarchy analysis to experts who have worked in nuclear power plants for more than 15 years. The analysis items of focus were the 3 attributes of strategic importance, urgency, and business feasibility of four major fields related to nuclear energy: nuclear safety, decommissioning, radioactive waste management, and strengthening industrial competitiveness.

Research in the Servitization of Manufacturing has become focused more on cases than concepts over the past decade. This is because governments have emphasized some practical research with policies to support their industries. Manufacturers need differentiated strategies to gain competitiveness by servitization in the global market. They should examine how common servitization has become in the same industries and markets. They should also make sure how it works and for what purpose it is done since it is necessary to make the best decision to be able to distribute the limited resources most effectively to defeat the global competitors. South Korea has the sixth largest trade volume in the world, but Korean SMEs' marketing capabilities fall short compared to that of major global companies. This paper seeks to develop the proper model and its application for the servitization with global cases which are recommended for Korean SMEs. They need to check the urgency in servitization according to their products, industries and target markets. In addition, factors such as purposes, time and types of the servitization are examined to see how they are related each other. The most significant implication of this study is that the processes for early-stage companies in servitazation are modeled to help them make the best choices.

Objectives: Overactive bladder(OAB), defined as 'urgency, with or without urge incontinence, usually with frequency and nocturia', is a major burden for patients and impairs quality of life. The aim of this study is to evaluate the cost-effectiveness of antimuscarinic agents for the treatment of overactive bladder including quality of life in societal perspective. Methods: A decision-analysis model was developed to compare the cost-effectiveness of solifenacin and tolterodine IR over 12 weeks. We used data from the published literature to develop the framework for the model. Resource utilization and costs were calculated with public institutional data and supplemented this information with clinical expert opinion, where necessary. Results: The expected costs per patient for solifenacin were 48,762 KRW less expensive than tolterodine IR over 12 weeks. Also, all outcomes including quality of life for solifenacin were more effective than tolterodine IR over 12 weeks. In conclusion, solifenacin dominates tolterodine IR and appears to be cost-effective options for the management of overactive bladder.

In this paper, we study the problem of how to design a medical-grade wireless local area network (WLAN) for healthcare facilities. First, unlike the IEEE 802.11e MAC, which categorizes traffic primarily by their delay constraints, we prioritize medical applications according to their medical urgency. Second, we propose a mechanism that can guarantee absolute priority to each traffic category, which is critical for medical-grade quality of service (QoS), while the conventional 802.11e MAC only provides relative priority to each traffic category. Based on absolute priority, we focus on the performance of real-time patient monitoring applications, and derive the optimal contention window size that can significantly improve the throughput performance. Finally, for proper performance evaluation from a medical viewpoint, we introduce the weighted diagnostic distortion (WDD) as a medical QoS metric to effectively measure the medical diagnosability by extracting the main diagnostic features of medical signal. Our simulation result shows that the proposed mechanism, together with medical categorization using absolute priority, can significantly improve the medical-grade QoS performance over the conventional IEEE 802.11e MAC.
