The purpose of this study is to inquire into the effect of characteristics of public enterprise CEOs' leadership (transforming leadership and transactional leadership) on the leader trust and organizational effectiveness of organizational members. A survey was made on 1,124 persons being in the service of 14 marketable and quasimarketable public enterprises. The results of this study were as follows. First, it showed that the individualized consideration had an effect on the confidence level of leader. Second, it showed that the transforming and transactional leaderships had an effect on the organizational effectiveness, which the hypothesis was adopted. Third, it showed that calculable, intellectual and identical factors had a positive effect on the job satisfaction and organizational commitment, but the organizational commitment of calculable variable was rejected in the confidence level. In general, the effect of transforming and transactional leaderships as public enterprise CEOs' leadership characteristics on the organizational effectiveness by mutual confidence level of calculable, intellectual and identical standards showed that the organizational commitment was rejected in the base of identification. And other factors were adopted as a positive mechanism, which they were a mechanism suitable to public enterprise CEOs' leadership characteristics.

The current study aims to address the relationships among conflict, person-organization fit, and workers' turnover intention. Specifically, it aims to examine whether person-organization fit mediates the relationship between conflict in team and turnover intention, also trust in leader moderates the relationship between person-organization fit and turnover intention. The empirical analysis shows that conflict is positively associated with turnover intention and have a negative impact on objective-value fit. The relationship between conflict and turnover intention is mediated by the person-organization fit. Trust in leader moderates the relationship between person-organization fit and turnover intention. The findings address the issue in terms of the mechanisms between conflict-turnover intention and the importance of trust in leader for an effective management of conflict in work teams.

The lack of customer satisfaction and trust remains a key barrier to electronic commerce. From the standpoint of online merchants, it is critical to build consumer trust by lessening sources of apprehensions and uneasiness associated with online transactions. This paper explores the relationships between customer satisfaction and intermediary's trustworthiness factors in B2C e-marketplaces. It also aims at examining the effects of consumer characteristics, including propensity to trust and Internet shopping self-efficacy, upon trust and purchase intentions. To meet the research objectives, an empirical study has been conducted by surveying 223 active e-marketplace buyers in Korea. The findings of the present research indicate that customer satisfaction positively affects all the three attributes of trustworthiness (i.e., competence, benevolence, and integrity), and more specifically it has a quite strong association with benevolence. In addition, propensity to trust has no significant influence on trust or purchasing intentions, and only affects benevolence and integrity with no direct effect on competence. Finally, Internet shopping self-efficacy was found to affect both trust and purchasing intentions, suggesting that e-marketplaces seek an online strategy designed to strengthen loyalty for customers with high self-efficacy, while they use a strategy to improve the usability and usefulness of their website to attract customers with low self-efficacy. The paper concludes with implications and directions for future research.

Online firms collect consumers' private information, which serves as a valuable database for marketing activities. In order to encourage consumers to provide their private information, online firms offer high quality websites for consumers who provide private information. However, identity theft, phishing, and pharming, become critical social issues, consumers started to avoid providing their private information to online firms. Thus, consumers often provide false or limited information, which lacks value for practical use for the online firms. The main issue raised in this study is to discuss how online marketing activities has influence on consumers attitude and information providing behavior. From the result, this paper found that websites reputation had greatest impact on willingness of providing information. Also this study revealed that unauthorized use is the key factor for increasing distrust and avoidance of providing information.

It's hard for hotel organizations to survive without adaptation to changing environment, and employees' positive attitude are required. The empirical objectives of the study include, firstly, to identify individual factors to influence hotel employees' attitude toward organizational change, secondly, to investigate the effects of the individual factors on their attitude toward organizational change mediated through trust in management Derived from existing literature, three underlying dimensions of the individual factors are given; (1) satisfaction with information, (2) freedom to express opinion, and (3) input from employees. An experimental design is applied to test four hypotheses that reflect the research questions. Five star hotels in Korea are targeted to be surveyed. A total of 156 faithful cases out of 300 cases are analyzed in this study. Descriptive statistics and multivariate analysis of variance, and SEM are utilized employing the SPSS and AMOS 7. Results of this study indicate that satisfaction with information, freedom to express opinion, and input from employees are significantly related to hotel employees' attitude toward change mediated through trust in management. At the same time, it shows that trust in management directly influences their attitude toward organizational change. In conclusion, the findings of the study contribute to hotel organizational development.

It becomes undeniable trends that offline shopping stores operate their own online shopping stores too. The multi-channel shopping stores like this allow consumers to have much choices to shop from either offline channel or online channel. This trend, however, also opens new research issues. Especially, we have found from literature survey that a new research model is necessary for more in-depth study of the consumer behavior analysis in the multi-channel trends like this, where those constructs such as offline trust, uncertainty, switching cost, and individual negative emotion are considered. It is noted, especially in the multi-channel environments, that uncertainty and switching cost need to be considered, and that individual tends to feel negative emotion much more. By relying on 406 valid questionnaires, we obtained empirical results such that switching cost and offline trust have a positive effect on continuance intention, and uncertainty tends to increase switching cost. Individual negative emotion also affects continuance intention significantly.

최근 개인자료의 유출 및 불법적인 사용이 사회적으로 큰 이슈가 되고 있어 개인의 정보보호 및 신분확인에 대한 요구가 증가하게 되었다. 이로 인하여 최근 안전한 데이터 전송과 거래를 위해 스마트카드의 이용이 증가되고 있는 추세이다. 특히 자바카드는 스마트카드 플랫폼에 자바의 기술을 접목시킨 것으로 양방향 통신, 정보의 보호기능 등을 수행할 수 있으며, 개인을 확인할 수 있고 이동성이 뛰어나며 복제가 어렵고 암호 알고리즘을 카드 내부에서 수행하여 보안상 매우 좋은 이점을 지니고 있어 스마트카드에서 필요로 하고 있는 다양한 서비스의 내용을 충분히 안정적으로 제공하고 있다. 본 논문에서는 이런 다양한 응용분야에 이용되는 자바카드의 보안성을 높이기 위하여 기존의 단순한 사용자 인증에 사용되는 PIN정보와 생체정보인 사인데이터를 함께 이용한다. 또한 개인에 따른 정보를 저장하는 방법과 이 정보를 접근하기 위하여 데이터를 사용하는 사용자간의 접근을 제한하기 위한 사용자의 접근권한을 설계하였다. 이와 같은 Applet을 설계함으로써 개인정보의 보다 안전하고 신뢰성을 보장하고 개인의 불법적인 유출 및 도용의 완벽한 제어가 될 것으로 기대된다.
