Coast guard organization has very different working environment with other general administrative organizations or police organizations. Because they are charging various coastal crimes and safeties by using war vessel at ocean, it was expected that in case of coast guard officers, the impact on organization commitment for each trust factor within organization has the differentiation with other administrative organizations. Core of results by conducting positive research is as following: It is indicated that for coast guard officer, organization trust factor most strongly impacts on organization commitment, and of social trust factors, colleague trust factor more impacts relatively than boss trust factor. Then, when searching the difference of trust factor recognition depending on population sociological properties of coast guard officers, it is indicated that the one having the experience of working at war vessel has more trust to its colleagues than the one having not and executives more trust their boss than non-executives. The reason why the trust to colleague is higher than to boss is recognized that it is caused from deep relationship with colleagues who work and live together when considering working conditions of security vessel.

Virtual Communities, which are formed on the Internet, are expected to serve the needs of members for e-collaboration, e-communication, information and knowledge sharing. The executives of organizations should consider virtual community as a new innovation or knowledge pool since members share knowledge. However, many virtual community have failed due to members' low willingness to engage and furthermore to share knowledge with other members. Thus, there is a need to understand and foster the determinants of members' sense of belonging behavior in virtual community. This study develops an integrated model designed to investigate and explain the relationships between contextual factors, personal perceptions of virtual community, usability, trust and sense of belonging in using a certain virtual community. Empirical data was collected from 201 and tested using structural equation modeling (SEM) to verify the fit of the hypothetical model. The results show that the perceived usability and community trust of members significantly influences sense of belonging in using the virtual community, and information quality, system quality, familiarity on the virtual community are significantly influence the usability but not reputation. And I confirmed that perceived shared vision and responsiveness play the role of determinants in making the member's trust, perceived risk influence the making community trust in directly. The results of the study can be used to identify the motivation underlying members' sense of belonging in a certain virtual community by investigating the impacts of contextual factors and personal perceptions on virtual community, the integrated model better explains behavior than other proposed models. This study might help executives of virtual communities and organizations to manage and promote these determinants of sense of belonging to stimulate members' willingness to engage the community and futhermore enhance their virtual community loyalty.

Traditional financial approaches have been failed to satisfy the firms in evaluating the payoffs from information technology(IT) investment. This research developed a processed-oriented model to evaluate the impacts of IT on the primary business activities within the value chain. The model proposed in this research incorporates corporate goals for IT and strategic alignment as key measurements of IT impacts. We found that corporate goals for IT can be classified into one of four categories: unfocused, operations focus, market focus, and dual focus(operations and market focus), using survey data collected from 137 corporate executives in Korea. The empirical analysis confirms that corporate goals for IT are useful indicators of impacts from IT in that executives in firms with more focused goals for IT perceive higher payoffs from IT in the value chain. We also found that strategic alignment contributes to higher perceived levels of IT payoffs.

The purpose of this study is to examine the mediating effects of job satisfaction of human service employees on emotional leadership-turnover intention relationship. Additionally, this study examines chief executive's employment type differences on results of the structural relationship. To examine them, employees from 56 local healthy family support centers in Seoul and Gyeonggi-do were surveyed and 295 of them were finally analyzed. The methodology adopted in this study is the structural equation modeling and multi-group analysis. The results of this study are as follows. Firstly, emotional leadership of supervisor has a significant influence on the job satisfaction. Secondly, it was found that emotional leadership and job satisfaction have a significantly negative effect on turnover intention. Thirdly, job satisfaction works as a mediator between the emotional leadership and turnover intention. Finally, it was confirmed that emotional leadership is a signifiant factor for job satisfaction, and that the paths vary with job satisfaction according to employment type of chief executives. Based on the above findings, theoretical and practical implications are discussed.

As the use of Information Technology is increasing, various kinds of IT service vendor proliferate. And most executives are trying to expand their field to online world. As the emphasis on Information Technology is inevitable, executives want to evaluate the service level they receive from IT service vendor. But. there's not yet the proper evaluation system for IT service. The evaluation systems like CMM, SPICE are process-focused. They don't give a look on the final product delivered to customer. On the other hand, the one that evaluate the customer satisfaction like ACSI, NCSI are too over-focused that they can't express the specific characteristics on the subjects that are deemed to evaluate. The focus is blurred. To overcome these limitations of existing framework, and to increase the value of evaluation, this study presents the evaluation system of IT service (afterwards, named as 'The new evaluation system') that derives process factors from IT service CMM, and evaluate customer satisfaction of IT service. Finally, the model was applied to the actual case to examine the practicality of the framework.

Company A, an embedded system manufacturer, has been managing multiple development projects. Executives need to understand the risk level of every project and prioritize resource distribution. Traditional project monitoring tools or excel sheets are too complex for calculating the risk factors across a functional organization. Two new charts, "Spear-head Chart" and "Float Chart" were designed to assist high level decision making processes. Two charts were used for weekly executive meetings in order to monitor project progress and rectify project direction. One page graphical monitoring tools in Company A are good enough for high management decision making. Authors explain the characteristics of two charts and propose its practical implementation in real working environment. Spear-head chart was also implemented as a system.

The importance of university technology transfer has widely been brought to the center of attention over the last decades. Research and practice thereby often concentrate on issues related to patenting and licensing or entrepreneurship but abstract away from relationship- and network-focused initiatives. In this paper, we argue that efforts to systematically develop close, long-term collaboration partnerships - although complex and resource intensive - are likely to be more beneficial for both universities and industry in the long run. Drawing on data derived from interviews with technology transfer executives of 22 leading European and U.S. universities, we analyze and discuss well-established practices of network and relationship management and their possible impact on technology transfer success. Our findings indicate that dedicated relationship management approaches can yield a sustainable competitive advantage for universities. We thereby shift the focus away from transaction-orientation towards more forward-looking relationship-centric approaches and discuss their institutionalization in great detail.
