Antigenic analysis of Herpes simplex type 2 virus was performed and its major antigen was localized using an immunoelectron microscopy. Antigens of 32, 43, 59 and 69 kDa were constantly expressed during the course of infection for 48 hr in the infected Vero cell. An antigen of 51 kDa was turned out to be the major one in inducing a immune response in Western-blot analysis. The 51 kDa antigen was localized on the surface of HSV-2 by immunoelectron microscopy using colloidal golds and anti-HSV 2 polyc1onal antibody. Immunofluorescence assay indicated that viral antigens were found throughout the infected cell and, especially, on the surface of the cell.

Based on the core value of the Q&A community, the contribution of knowledge and information has a great impact on users' community evaluation. As a small social group, the relationships and interactions among community members are quickly formed through information technology. As such, the cognitive evaluation of the relationship between community members will have an impact on the intention of information contribution. This research builds on the previous research based on the social exchange theory and establishes a dual model of swift guanxi in examining the relationship between guanxi and continuous knowledge contribution. In the current study, 305 survey questionnaires were used and 249 valid questionnaires were used for analysis. The analysis results are as follows: First, information support has a positive impact on dedication-based swift guanxi. While hypothesis between information support and constraint-based swift guanxi was not be supported. Second, emotional support has a positive impact on the formation of swift guanxi from a dual perspective. Third, the swift guanxi from the dual perspective has a positive impact on the intention of continuous knowledge contribution. Finally, although personal involvement has an adjustment effect, it is a downward adjustment effect, hypotheses are not supported. The current study offers theoretical and practical implications in field of knowledge management, specifically knowledge contribution in the virtual community.

The Korea-EU FTA has substantially escalated the volumes of South Korea's export and investment in the United Kingdom since its ratification. Coupling with the FTA effect, the ease of doing business in the United Kingdom will increase even more trade and investment by South Korean multinational corporations. In the meantime, the UK Bribery Act 2010 was enforced to end bribery by individuals and business entities which have close connection with the United Kingdom. The punishment of violating the Act is severe than ever because of "unlimited" fine. Without fully understanding the Act and have compliance measures as described in the Guidance issued by the UK Ministry of Justice, South Korean corporations may risk its whole business. Therefore, this paper will analyze the UK Bribery Act in details to provide critical implications for South Korean corporations under the Korea-EU FTA.

With the explosion of SNS(social network services) users, the social commerce market has emerged as a new consumer market, and will continue to grow in recent years. Despite the market environment, however, studies are lacking as to the causes of frustration that are hurting social commerce activation. This study is based on the 'Hezbollah' 2 Factor Theory and is a study of social commerce users' satisfaction and frustration factors. For this purpose, social commerce site characteristics and user characteristics were first derived from interviews and literature reviews to confirm their relationship to satisfaction and dissatisfied products. The results showed that the price discount rate, diversity, regional infrastructure, and e-commerce familiarity resulted in the impact on the definition of satisfaction, while the price discount rate, interoperability and innovation resulted in the definition of unsatisfactory goods. It also showed that satisfaction affects the definition of intended use. In particular, the price discount rate was found to be the only factor affecting the definition of unsatisfactory as well as affecting the definition of satisfaction.

In proposing the concept of flow which focuses on experiencing the sites visited by Korean wave tourists as induced by drama or movies, this paper investigated role of involvement variables for Korean wave tourists in influencing flow construct of film sites. The involvement of Korean wave was found to operate as a mechanism by which challenge, skills, focused attention on site might be more organized or more actively experienced. This recognizes that there is clearly a need for making the FIT sites exposed much by any mix of various media. This study showed that challenges and skills influence enjoyment as output factor of flow film site visitors are assumed to participate the roles of film characters, experiencing the places and atmosphere. The degree of visitors' reflections in the film optimizes awareness of flow experiences on the site. Therefore, it is necessary to provide more detailed experiential program on the film sites with the wide variety of flow-related contents in the film.

Purpose : Cysteinyl leukotrienes are important inflammatory mediators in the pathogenesis of asthma; therefore interruption of cysteinyl leukotrienes by leukotriene receptor antagonists improves clinical symptoms in the management of patients with mild to moderate asthma. We evaluated whether clinical response to montelukast, a leukotriene receptor antagonist, in childhood asthma was predicted by genotypes of leukotriene $C_4$ synthase($LTC_4S$) promoter gene polymorphism. Methods : An 8-week prospective, open trial of montelukast was carried out in 161 children with mild to moderate asthma. Genotyping of $LTC_4S$ gene polymorphism was determined by restriction fragment length polymorphism. Results : The distribution of the $LTC_4S$ genotypes AA, AC, and CC was 70.8 percent, 23.6 percent, and 5.6 percent, respectively in asthma group and 74.0 percent, 22.6 percent, and 3.4 percent, respectively in control group. A statistically significant difference in the distribution of $LTC_4S$ genotype was not observed between the asthma and the control groups, and there was no significant difference between the $LTC_4S$ genotype and asthma severity. The responders to montelukast were significantly prevalent in the mild asthma group(P<0.05). There was no significant difference in the distribution of the responders compared to non-responders within genotype in the total asthma group or the moderate asthma group. However, the responsiveness for montelukast was significant difference within genotype for both AA and AC/CC in the mild asthma group : The AA genotype was more included in the responder group(P<0.05). Conclusion : In the mild persistent asthma group, the A allele of $LTC_4S$ polymorphism may be regarded as a predictable factor for clinical response to montelukast. However, LTC4S polymorphism was not significantly associated with the clinical response to montelukast in asthmatic children.

Surface electromyography (sEMG) is mainly used as an on/off switch in the early stage of the study and was then expanded to navigational control of powered-wheelchairs and recognition of sign language or finger gestures. There are difficulties in communication between people who know and do not know sign language; therefore, many efforts have been made to recognize sign language or finger gestures. Recently, use of sEMG signals to recognize sign language signals have been investigated; however, most studies of this topic conducted to date have focused on Chinese finger number gestures. Since sign language and finger gestures vary among regions, Korean- and Chinese-finger number gestures differ from each other. Accordingly, the recognition performance of Korean finger number gestures based on sEMG signals can be severely degraded if the same muscles are specified as for Chinese finger number gestures. However, few studies of Korean finger number gestures based on sEMG signals have been conducted. Thus, this study was conducted to identify potential forearm muscles from which to collect sEMG signals for Korean finger number gestures. To accomplish this, six Korean finger number gestures from number zero to five were investigated to determine the usefulness of the proposed muscles and electrode placements by showing that CNN technique based on sEMG signal after sufficient learning recognizes six Korean finger number gestures in accuracy of 100%.

ESG has become a necessity for all companies, and major Korean banks are actively practicing ESG management. Banks are playing a role in providing ESG finance as intermediaries in the supply of funds. Recently, they have launched ESG digital banking products that offer preferential interest rates for eco-friendly activities in combination with digital technologies. However, indiscriminate provision of preferential interest rates can adversely affect profitability of banks, and they may face the problem of 'Greenwashing' if they do not contribute to improving environmental awareness. Therefore, this study selected ESG digital savings products linked to electricity savings as the subject of the study, and empirically analyzed consumers' environmental awareness and savings behavior through actual data of consumers (N=2,478). The main findings of this study are as follows First, the analysis of the consumer status of ESG digital banking products shows that the 30-50s are the main consumer base, and the MZ generation shows relatively high performance in achieving preferential interest rates through electricity saving practices. Second, consumers' environmental awareness has a significant impact on achieving the goals of ESG banking products. ESG banking products can contribute to environmental awareness while fulfilling the basic function of saving. Third, environmental awareness did not drive consumers' savings contribution behavior, suggesting the need for continued consumer engagement. Based on environmental awareness and the theory of saving behavior, this study provides a theoretical explanation in ESG financial products. The results suggest that the appropriateness of the preferential interest rate design of ESG financial products is important.

The purpose of this paper is to recognize and embody the implications of the concept of interactivity. Among the many types of interactivity already proposed, this paper sheds light especially on the so-called contingent interactivity. The contingency means a condition in which a particular performance or selection of a subject is considered neither necessary nor conclusive, and also the potential for various activities of this subject. The contingent interaction comes into being when the involvements of users in dealing with a message or content are experimental or creative. The interaction does not orient toward the completion of content or the immersion to a particular reality. Rather, the results of a user's contingent performance are not the finalized content and have characteristics that lead to the continuous modification. In order to embody this meaning of contingent interactivity, the paper examined the two example, the film re-cut and game modding. In both cases, it is comprehensive that the user of these two new media activities lies in the contingent situation.
