Emulsion PCR (ePCR) has recently gained interest in the areas of food safety and biotechnology owing to its highly specific and sensitive performance in the amplification of target DNA. To facilitate the applications of ePCR to food safety and biotechnology, this paper describes the principles of ePCR and the factors that should be considered in designing ePCR. In addition, current research and applications related to ePCR are discussed.

본 연구는 제조자(공급자)와 중간분배자로 구성된 공급사슬에서 시간에 따라 일정률로 퇴화하는 퇴화성 제품을 다루는 중간분배자의 신뢰성있는 재고보충정책을 분석하였다. 문제 분석을 위하여 제조자는 고객의 수요를 증대시키기 위한 수단으로 중간분배자로부터의 제품대금에 대하여 일정기간 동안 신용거래를 허용한다는 가정과 함께 수송량에 따라 할인되는 수송비를 고려하여 모형을 수립하였고, 중간분배자의 경제적 재고보충정책을 결정하기 위한 해법을 개발하였다.

Supply Chain Management(SCM) system is a critical investment that can affect future competitiveness and performance of a company. Selection of a right SCM system is one of the critical issues. This paper provides the characteristic factors of SCM system selection and the SCM system evaluation and selection model based on Analytic Hierarchy Process(AHP). The proposed model can systematically construct the objectives of SCM system selection to support the business goals. A empirical example demonstrates the feasibility of the proposed model and the model can help a company to make better decision-making in selecting SCM system.

The complexity of safety critical systems of Nuclear Power Plant continues to increase rapidly due its transition from analog to digital systems. It has thus become progressively more imperative to model these systems prior to their implementation in order to meet the high performance, safety and reliability requirements. Timed Petri Nets (TPNs) have been widely used to model such systems for non-functional analysis. The paper presents a novel methodology for the analysis of the performance metrics using PN modeling. The paper uses the isomorphism property of the TPNs and the Markov chains for the performance analysis of the safety critical systems. The presented methodology has been validated on a Shutdown System of a Nuclear Power Plant.

Since 9.11 terrorist attacks against the USA, the new paradigm for "supply chain security" has been established. And at the same time a lot of researches are being made on supply chain security by many foreign companies or research institutes. However, domestically the terms "supply chain security" themselves are not yet familiar, and the paradigm of security are not being used in the logistics, while little researches are being made on them But recently along with development of "ConTracer," a supply chain security technology, which is to be used as the equipment for container cargo transportation safety based on RF1D technology, related researches have begun to be activated. The key issues for the development of equipment for container transportation safety are to obtain both a high recognition rate and enough recognition distance. To this end, this study has tested the ConTracer (433 MHz type and 2.4 GHz type) by using Taguchi Method. According to our test results, in the case of 433 MHz type, it is a little more effective that the reader faces to the front-right side, and in the case of 2.4 GHz, reader direction does not make difference in the view of sensitivity. The test also has proved that it is better that antenna location, as expected, is to be installed on the outside for both types alike.

Background: In this study, we compared the incidents of humidifier disinfectants and incidents of mild hepatitis in Japan to highlight the differences in government response in the health care field in terms of "chain of responsibility". Methods: We examined whether the three mechanisms of action and the chain of responsibility hypothesis were applied to compare the cases of Korea and Japan. The incident of Japan occurred in 1987 in Misawa city, Aomori prefecture. In the 1990s, the safety of blood products increased dramatically. However, relief for infected victims was neglected. Green Cross did not notify the parties. In Korea, in the spring of 2011, a number of lung disease patients were accidentally admitted to a hospital in Seoul, and a female patient with respiratory failure symptoms expired. The Korea Centers for Disease Control and Prevention conducted animal tests and the Ministry of Health and Welfare issued an order for forced collection of humidifier disinfectants. Results: In the case of Japan, the Ministry of Health and Welfare had to take responsibility for follow-up measures such as the investigation of the cause, so it was tied to a "chain of responsibility". However, in the case of Korea, the Ministry of Health and Welfare was free from the chain. Conclusion: Through the comparison between the cases of Japan and Korea, we confirmed that whether or not a government organization chooses to conceal responsibility depends on its past behavior, which is whether it is free from the chain of responsibility or not. Therefore, it was reaffirmed that an organization (ministry or department) free from the chain of responsibility must exist within the government.

In recent years, as there is growing concern with ESG (Environmental, Social, and Governance), the strategic direction of business management is changing from maximizing shareholders wealth to maximizing stakeholders value. ESG is reshaping a corporation's supply chain management strategies. The purpose of this study is to explore the ESG challenges in supply chain management. As a result of network text analysis and topic modeling analysis on 3226 news articles, 'Suppliers', 'Sustainability', 'Shared Growth' 'Carbon Neutral', 'Safety and Health', 'Responsible Business Alliance', 'Supply Chain Due Diligence Law' were identified as the main issue. Since ESG initiatives in the supply chain are not limited to the efforts of individual firms, future research should focus on figuring out what difficulties and challenges exist in the diffusion of ESG practices along multi-tiered supply chains, and how to overcome them.

Prior studies focusing on safety behavior have not given sufficient consideration to the potential impact exerted by different leadership styles. Of these various styles, my attention is specifically drawn to the influence of ethical leadership on safety behavior. In this paper, I delve into the influence of ethical leadership on safety behavior, shedding light on both the underlying mechanisms(mediators) and a significant contextual factor(moderator). I probe into the successive mediating roles of employees' trust in the organization and their commitment to it, within the context of the relationship between ethical leadership and safety behavior. Further, I posit that authentic leadership positively adjusts the connection between ethical leadership and organizational trust. My findings underscore that ethical leadership enhances employee safety behavior, facilitated by the chain mediation of trust in the organization and organizational commitment. Moreover, I discover that authentic leadership, as a positive moderator, magnifies the favorable impact of ethical leadership on organizational trust. This paper will also articulate the theoretical implications, practical applications, and limitations of the study.
