The electronic medical device industry and the relevant market have been greatly expanded owing to various factors, such as the advent of the aged society and the spread of the desire for well-being in developed countries, and rapid development of China, India and other emerging markets. The electrical stimulator is one of electronic medical devices most commonly used in homes. The electrical stimulator is widely used for pain relief, rehabilitation, muscle conditioning and others. Since it is mainly used in homes, it is very important to assure the safety and performance for protection of users. However, there is no guideline on evaluation of safety and performance of such electrical stimulator for home use. In this study, various local and foreign references were reviewed to develop the internationally harmonized procedures for safety and performance evaluation of the electrical stimulator and test items, specifications and methods are proposed. In addition, such proposed test items were validated to decide the internationally harmonized tests for safety and performance evaluation. This study will contribute to improvement of quality and safety of electrical stimulators for home use and help the Korean medical device industry have the international competitiveness.

The purpose of this study is to analyze the locational characteristics and viabilities of township enterprises in Yan bian korean ethnic autonomous district. From the late of 1970s, Chinese township enterprises have heavily contributed to the rapid economic development in China, to alleviating the rural, surplus labor, and to reducing the dispa rity between urban and rural in term of socio-economic condition. From the late 1980s Chinese township enterprises in Yan bian korean ethnic autonomous district have rapidly developed in urban areas and also in the places that were easily accessed into main cities. The locational characteristics implied the management characteristics that attempted to solve the lack of capital and technique, and marketing difficulties through the existed firms in urban areas rather than the accessibility of the market. Chinese township enterprises in Yan bian korean ethnic autonomous district utilized locally available low wage labors of legal agrarian(nung-min-gung) to compete the large firms in urban areas. Township governments positively affected the development of the enterprise in the early stage: while, in the latter stage, they limited the autonomous management. If the economic ,system in China would be changed into the capital in the future, the institution should at low to the maximum autonomous management of township enterprises.

The purpose of this study is to examine a direction for contents choice and transmission strategies of radio literature reading programs. For this, 129 picturebook contents used for EBS program of "children books for adults" in recent 6 months were collected and analyzed quantitatively and qualitatively based on Nicholajeva's societal and aesthetic approach. In terms of external literary elements, there were unequal distribution of published period, nation, company and genre. In terms of literary inner factors, they were excellently reflecting the stream and the tendency of modern children literature. Finally, in the process of turning visual texts into auditory texts, the program used diverse auditory transmission strategies. Based on these results, it is suggested that this program need to take into account reforming the contents selection practice to provide abundant literary experience for listeners and sophisticating the transmission effects adapted for a digital era.

In the context of knowledge sharing, network position has been a controversial subject. A central position in the network provides access to non-redundant knowledge, leading to more opportunities of knowledge sharing. On the other hand, as "bridging" relationships, its characteristics as a "weak tie" suggest innate lack of trust and reciprocity which is considered an impediment to share knowledge. This paper attempts to enlighten the underlying dynamic by examining the interaction between network centrality, motivation and ability in knowledge sharing. Furthermore, this paper examines the concept of knowledge sharing ability in depth by operationalizing the construct into three aspects: extensive and diverse knowledge, social media utilization ability and self-efficacy. The results show a partially supported three-way interaction, where the highest level of knowledge provision is reported when the employee has low network centrality, high autonomous motivation and high knowledge sharing ability, i.e. extensive and diverse prior knowledge. Though all models indicate strong associations between network centrality and knowledge sharing, this suggests an even greater power of motivation and ability that gives the strength to overcome unfavorable environments of peripheral position. Therefore, this paper offers an alternative explanation to the existing debate whether network centrality positively or negatively influences knowledge sharing.

Due to the development of information and communication technology, the global influence on politics, economics, society, and culture has grown. A major example of this impact on the economic sector is the growth of e-commerce, which increases both the speed and efficiency of businesses. In light of these new developments, businesses need to shift away from the misconception that information overwhelms to embrace the enhanced competitiveness that e-commerce provides. However, concern about fraudulent transactions through e-commerce is pertinent because of the loss in both critical revenue and consumer confidence in open markets. Current solutions for fraudulent transactions include real-time monitoring and processing, payment pending, and confirmation through SMS, E-mail, and other wired means. Our research focuses on the management of Fraud Detection Systems (FDS) to safeguard online electronic payment systems. With effective implementation of our research we hope to foster an honorable online trading culture and protect consumers. Future comparative research in domestic and abroad markets would provide further insight into preventing fraudulent transactions.

The study explores how the discourses on game addiction, which emphasize diligence and sincerity for labor and self-control, and professional gamers, who are trapped in pleasures of playing games in the virtual world, cohabit in Korean society. Progamers have grown from entertainment industry enlarged along with the current of the economic 'postmodernization,' mentioned by Hardt and Negri(1997; 2001; 2004). Hardt and Negri have elaborated on the economic postmodernization with the notion 'immaterial labor,' which blurs the line between economic (instrumental) actions and humane qualities as well as pertains to the potentiality of resistant practices against the power of modernity. From this perspective, progamers' labor is understood as 'affective labor,' an aspect of immaterial labor with the potentiality of resistance. However, meticulous examination of progamers' labor in this study reveals that progamers control their affects systematically, strategically, and rationally for their materialistic success. Progamers, while performing postmodern mode of labor, are subordinate to modern work ethics, which lead them to lose the potentiality of resistance. Consequently, while the discourses on game addiction and progamers outwardly form sharp contrast to each other, the two indeed are placed in tandem in the vein of modern work ethics of Protestantism.

This study seeks to clarify the background and factors for the expansion of bus networks that connect Incheon International Airport with its hinterlands. For this research objective, this paper analyzes the relationships among the change of bus routes, competitive transportation modes, passenger fares, and the shortest time distance. Previously, the hinterlands of route bus networks that connect Gimpo International Airport were Seoul metropolitan area, Chungcheong region, Jeonju and Iksan in Jeollabuk-do(province). However, the opening of Incheon International Airport resulted in the expansion of the hinterlands of bus networks to Gangwon-do, Gwangju, and major cities in Youngnam region. Simultaneously, route bus networks also expanded in Seoul metropolitan area. Each bus route connecting Incheon International Airport with its hinterlands was opened by a single bus company or various bus companies. In many cases, due to the uncertainty of revenues or bus company's regional ties, a bus route was opened by various bus companies. In this paper, the analysis of the number of one-way route bus service and density of flight passengers shows that the frequency of the route bus service for Seoul except Gangseo-gu(ward) and for Seoul's satellite cities(Suwon, Seongnam, Anyang, Gunpo, Guri, and Osan) should be decreased. The analysis also shows that the frequency of the route bus services for the other cities, counties(Guns), and wards(gus) should be increased. In Seoul metropolitan area, although route bus fares are more expensive than subway fares, passengers use route bus more frequency than subway because time distance of route bus is shorter than that of subway and subway transfer is inconvenient. In general, outside Seoul metropolitan area, air flight is preferred in the regions that have airports. In contrast, the route bus is preferred in Daegu and other regions that do not have airports.

School science practical work is often criticized as lacking key elements of authentic science, such as peer argumentation or debate through which social consensus is obtained. The purpose of this paper is to review the recent studies about the argumentation and to explore the conditions and the model of argumentative scientific inquiry, which is specially designed open inquiry in order to facilitate students' peer argumentation. For this purpose, a theoretical discussion for the argumentative scientific inquiry as the way of authentic inquiry in schools was developed. The conditions for argumentative scientific inquiry were found to be the following: multiple arguments, students' own claims, opportunities for oral and written argumentation, equal status of debaters, and community of cooperative competition. For these conditions, the argumentative scientific inquiry was organized into experiment activities and argumentation activities. During argumentation activity, students should be guided to advance written argumentation through writing a group report for peer review and oral argumentation through a critical discussion. Through the argumentation between groups and in group, the students' arguments would be elaborated repeatedly. The feedback from argumentation links experiment activities to argumentation activities. Hence, the whole process of this inquiry model is circular.
