Innovation becomes norm rather than exception in today's business, and accordingly firms are working on how to make their employees to work smarter using information systems and technologies. Smart work demands virtual collaboration and cooperation among team members in different places and different time. Sharing of knowledge among team members in these innovative activities are critical in every sense for the successful performance. This study explores the antecedents of knowledge sharing among team members in team-based innovation activities. Five factors (pleasure of knowledge sharing, self-efficacy, management support, rewards, and system usage) are identified through extant review of literature and an instrument is adopted and validated from previous studies. The instrument is adminitered against 138 individuals in and across 54 teams in a telecommunication firm. Except self efficacy, all the paths in the proposed research model is confirmed with different levels of relational coefficients towards the levels of knowledge sharing and innovation activities in teams. Surprisingly, findings indicate that intrinsic pleasure of sharing is most critical than management support, organizational rewards or system usage. This study fills the research gap in team management. Findings provide important implications for managing teams in coming virtual and smart environment.

Purpose As web 2.0 has taken root in the Internet environment, people began to create specific values to produce and disseminate contents on their own. In order to emphasize the personalized media attributes, the concept of self media was derived. In this paradigm shift, self media has emerged that succeeded in commercializing themselves in social media. Taking advantage of the influence of self media will have a tremendous positive impact on management activities such as marketing strategy, brand promotion, customer retention, and profit growth. This study examines the factors affecting the loyalty of self media in Korea and China because the studies in the area of selfmedia is not enough. Design/methodology/approach This study analyzed what factors influenced the loyalty of self-media in terms of Korea-China comparison. The research model was proposed on the basis of previous research papers. Content value, interactivity, ease of access, self-congruity, sympathy, and reputation were used as independent variables. Trust and satisfaction are used as mediating variables, nationality as moderator variables, and loyalty to self-media as a dependent variable. Results As a result, it was found that all independent variables directly influence the loyalty of self-media except interactivity, and interactivity indirectly influence loyalty through trust and satisfaction. There was a moderating effect of nationality between satisfaction and loyalty, but was not a moderating effect between trust and loyalty.

Korea is leading in G20 summit beginning in 2011 and the 19th United Nations World Tourism Organization(UNWTO) to attract international conferences and meetings. The interests on MICE have been increasing. The MICE, from the mid-l990s, was launched in Singapore in terms of the convention industry leader in Asia, stands for corporate a generic term of Meeting, tourism award Incentive, Convention, and Exhibition. The MICE has been showing many good results as a golden industry such that no pollution has occurred and the effect is very large invisible value can be created because most of the participants in international conference are opinion leaders in each country and they can be Korea brand promoters in their home country after attending the conference and returning to. Korea has been ranked at the world's 11th most-popular destination for international business meetings, confirming its world-class reputation for business events. Korea cities also featured highly on the list. Seoul was ranked seventh globally, while Busan jumped to sixth in Asia and Jeju came in at number eight. Changwon, Daegu, Daejeon, Gyeongju and Gwangju also made their debuts on the Asian list. Consequently, the economic & political effects of MICE industry were investigated and accordingly the revitalization of the global MICE bureau was discussed.

Geographical indications are place names (in some countries also words associated with a place) used to identify the origin and quality, reputation or other characteristics of products. Protection required under the TRIPS Agreement is defined in two articles. The purpose of this study is to select the representative geographical indication item of Korea, discuss of the new intellectual property rights, and promote the trade of that product. It is also discussed of a geographical indication registration system and the recognition with international point of view. The international geographical indication protection is strengthening in recent. There are many multilateral and bilateral discussions and talks for geographical indication system. In order to protect excellent Korean products locally and internationally, the 'Quality Management of Agricultural Products Act' has been introduced form July 1, 1999. The geographical indication registration of Korea currently is 31 cases. The geographical indication is limited the regional promotion in Korea. Therefore, it is studied the registered items on the list and analyzed the result of the registration. Consequently, this paper suggests that more effective ways have to be prepared for the systematic management of geographical indications, campaigns for the recognition as a property.

A mobile ad hoc network(MANET) is a network where a set of mobile devices communicate among themselves using wireless transmission without the support of a fixed network infrastructure. The use of wireless links makes MANET susceptible to attack. Eavesdroppers can access secret information, violating network confidentiality, and compromised nodes can launch attack from within a network. Therefore, the security for MANET depends on using the cryptographic key, which can make the network reliable. In addition, because MANET has a lot of mobile devices, the authentication scheme utilizing only the symmetric key cryptography can not support a wide range of device authentication. Thereby, PKI based device authentication technique in the Ad Hoc network is essential and the paper will utilize the concept of PKI. Especially, this paper is focused on the key management technique of PKI technologies that can offer the advantage of the key distribution, authentication, and non-reputation, and the issuing and managing technique of certificates based on clustering using Threshold Cryptography for secure communication in MANET.

A mobile ad hoc network (MANET) is a collection of mobile nodes communicating in an infrastructure-less environment without the aid of a central administrating authority. Such networks entail greater dependency on synergy amongst the nodes to execute fundamental network operations. The scarcity of resources makes it economically logical for nodes to misbehave to preserve their resources which makes secure routing difficult to achieve. To ensure secure routing a mechanism is required to discourage misbehavior and maintain the synergy in the network. The proposed scheme employs a partially distributed dynamic model at each node for enhancing the security of the network. Supplementary information regarding misbehavior in the network is partially distributed among the nodes during route establishment which is used as a cautionary measure to ensure secure routing. The proposed scheme contemplates the real world scenario where a node may exhibit different kinds of misbehavior at different times. Thus, it provides a dynamic decision making procedure to deal with nodes exhibiting varying misbehaviors in accordance to their severity. Simulations conducted to evaluate the performance of the model demonstrate its effectiveness in dealing with misbehaving nodes.
