Purpose - The purpose of this study is to identify team commitment affecting employees' innovative activities and factors affecting team commitment including empowerment by leaders and job enrichment factors. In other words, so as to explain outcome variables of innovative activities, this study aims to emphasize employees' attachment roles towards their groups within nomological network, and identify the motives encouraging employees' innovative activities. The research purpose is significant due to the realistic situation of hotel industry. The reason why innovative activities are important can be found in recent changes of business environment. Also, unlike other various studies on precedence factors encouraging employees' innovative activities, this study classified those precedence factors into job and leader characteristics, and it emphasized the importance of team commitment as the process that job and leader characteristics are connected to innovative activities. Research design, data and methodology - The survey for this study was conducted during October 6^th ~ November 10^th in 2014 to the employees who are working in 5-star hotels in Korea. As for the selection of hotels and sampling method, convenience sampling method was used to the employees in 5-star hotels. Self-report method was used in the survey, judging that the employees' characteristics would be relatively homogeneous. 311 questionnaires were distributed in total, and 275 reponses were collected. After excluding the missing and unreliable responses, 245 questionnaires were used in the research. SPSS and AMOS programs were used for the analysis. Results - First, empowering leadership had positive effects on hotel employees' team commitment. It indicates that hotel employees are more committed to their team when their leaders set examples, provide information, and involve employees in decision-making process. Second, as a result of the relationship analysis in task diversity, task significance, task identity and team commitment, task diversity and task significance had significant effect on team commitment, while task identity had no significant effect on team commitment. It indicates that team commitment is enhanced when the employees can conduct diverse types of jobs and get more opportunities to talk with the guests. Also, the repetition for the same jobs in hotel rooms and the space for preparing food and beverage do not lead to team commitment, even though the employees fulfill their duties to the end. Third, hotel employees' team commitment has positive effect on their innovative activities. It indicates that employees voluntarily conduct innovative activities when they are attached to their team and identifies themselves with the team. Conclusions - There are theoretical and practical implications in this study. First, in terms of the theoretical perspective, this study proposes structural framework in team commitment, and it identifies the psychological mechanism in team commitment from the aspect of social exchange, which resulted in identification of precedence factors related to team commitment. In addition, this study presents new possibilities for relevant studies about team commitment by examining the effect on team commitment when the importance of innovative activities is emphasized in recent business environment.

In earlier investigations, seeds of Perilla frutescens(L.) Britt. cv. Chookyoupjaso were irradiated with 200 Gy gamma ray to generate mutagenesis. The aim of this study is to investigate the effects of a hexane extract from Perilla frutescens (L.) Britt. cv. Chookyoupjaso mutant 45 on the actions of anti-inflammatory activity on inducible nitric oxide synthase, and an identification of the major active compound. The hexane extract from P. frutescens exhibited activity of inhibition of a NO production ($IC_{50}$, $295.1{\mu}g\;ml^{-1}$). The hexane extract was further divided into subfractions by silica-gel chromatogarphy. Inhibition of the NO production by various fractions was assayed in LPS-stimulated RAW 264.7 cells. Among the seven fractions, the 5th fraction was the most effective ($IC_{50}$, $19.5{\mu}g\;ml^{-1}$). The 5th fraction suppressed the expression of protein of iNOS in LPS-induced RAW 264.7 cells, and GC/MS analyses showed that isoegomaketone is a major bio-active compound in the 5th fraction. The result indicated that isoegomaketone has a good potential to be developed as an anti-inflammation agent.

Today, change in the information technology field is very fast, the innovative technology or product to be released for the other sectors tend more frequent. In this situation, most of potential users should think carefully about the adoption of innovative technology such as Web2.0. On the other hand, the adoption or acceptance of innovative technology has the paradox of technology. In order to verify the acceptance factors of innovative technology, we are proposed the model based on the DOI and MIR. Conceptually, we examine the four independent variables such as relative benefit, compatibility, complexity, risk that are divided into two parts as positive and negative, a moderating variable effect on independent variables that is the social influence, and their impacts on the acceptance of new technology. The questionnaire which consists of 100 questions was used to analyze the result to IT suppliers and customers in public sector. Finally, our research model was tested in an empirical study, which confirmed all of our hypotheses.

Retail space itself could be one of the marketing strategies, through creating space, and communicating brand identity. Especially for innovative products, such as mobile technology products, store is not just to sell products but to provide experiences so that users can fudge usefulness of products and reduce uncertainties to adopt the products. The purpose of this study is to investigate how environmental features and physical artifacts contribute to promote experiences of innovative products in stores and how physical environment help to establish brand identity. For this study, site visits, observation, and literature review were conducted. For case studies, three retail spaces (Apple, Iriver, Sony) and one service space(TTL) were selected. Compared to the service space, three retail spaces have more transparent and open store front design characteristics. For the experiences of shoppers, products displayed in a radial shape, round shape, column shape, and around peripherals of the stores. A service oriented space, TTL zone is differentiated from three retail spaces in terms of layout, store front design, and experience areas. Compared to the traditional stores selling innovative products, the case stores showed more warm atmosphere using various shape, wood materials, lighting fixtures and furniture.

Employees' knowledge integration capabilities and innovative behavior are still of crucial importance in the effective knowledge management. Recently researchers and practitioners are interested in both the potential benefits of unlearning and the negative aspects of learning inertia. The purpose of this study is to examine the relationships among learning inertia, unlearning, knowledge integration capabilities(knowledge exploitation and knowledge exploration) and innovative behavior. The results of analysis show that learning inertia is employees' psychological obstacle factor affecting knowledge integration capabilities and unlearning, that unlearning of employees is a key factor affecting knowledge integration capabilities, and that knowledge integration capabilities are driving forces leading to innovative behaviors of employees. For theoretical and practical implications, the research presents the grounds for arguments that knowledge integration capabilities are employees' dynamic capabilities from the knowledge management perspective, that unlearning is a driving force of employees' positive behaviors, and that organizations trying to perform the dynamic knowledge management need to identify the causes of employees' psychological resistance to learning. Limitations arisen in the course of the research and suggestions for future research directions are also discussed.

A design study was performed to improve the limit aseismic performance (LSP) of a primary heat transport system (PHTS) pump. This pump is part of the primary equipment of a prototype generation IV sodium-cooled fast reactor (PGSFR). The LSP is the maximum allowable seismic load that still ensures structural integrity. To calculate the LSP of the PHTS pump, a structural analysis model of the pump was developed and its dynamic characteristics were obtained by modal analysis. The floor response spectrum (FRS) initiated from a safety shutdown earthquake (SSE), 0.3 g, was applied to the support points of the PHTS pump, and then the seismic induced stresses were calculated. The structural integrity was evaluated according to the ASME code, and the LSP of the PHTS pump was calculated from the evaluation results. Based on the results of the modal analysis and LSP of the PHTS pump, design parameters affecting the LSP were selected. Then, ways to improve the LSP were proposed from sensitivity analysis of the selected design variables.

In the manufacturing industry, fostering talented workers has become a core activity as well as an important resource leading to manufacturing enterprises' innovative activities, which has come to the fore as one of the biggest success factors for innovative activities indeed. In other countries, there are many researches actively conducted on talent-fostering programs related to manufacture innovation. In Korea, however, manufacturers or several different education agencies don't actively carry out manufacture innovation instructions and have failed to faster special competent workers since their instructions focus on theories most of the time. Therefore, this study was conducted to understand the present conditions of manufacture-innovative instructions in Korea by classifying them in a method of educational technology and to investigate various teaching methods through oversea cases and cases from non-manufacture fields so that it might make a proposal for a better manufacture-innovative instruction method.
