  • It is estimated that electronic commerce facilitates international trade and lower transaction cost and help firms make the best of the opportunities of market access. The comprehensive programs had been implemented to provide better electronic commerce environments by international organizations such as OECD, UNCITRAL, APEC, ICC and etc. Especially, WTO plays the most important role to implement efficient forms and rules on electronic commerce after Doha Ministerial Conference. Member countries recognize the need to conduct the electronic commerce in compliance with the principles and rules of WTO. However, there are many issues to be solved such as the clarifications of concepts and definitions, the possibility of adaptation of technological neutrality in GATS, the imposition of taxation in electronic commerce transactions and the methods of protecting copying as well as trademark. The Implementation of concrete forms and rules of electronic commerce in the WTO will be influential to international trade as the member countries have to adapt them in their transactions. Considering that further discussion will be continued in GATS, we need to analyze the problems and strategies for electronic commerce. As there are not concrete international laws for e-commerce, the existing laws must be revised and changed and each country need to present the enactment direction of e-commerce law to streamline e-commerce and to prevent trading partners from conflicting due to legal problems.

  • The secure group communication enables the members, which belong to the same group, to communicate each other in a secure and secret manner. To do so, it is the most important that a group key is securely distributed among them and also group membership is efficiently managed. In detail, the generation, the distribution and the refreshment of a group key would be highly regarded in terms of low communication and computation complexity. In this paper, we show you a new protocol to generate a group key which will be safely shared within a group, utilizing the 2-party Diffie-Hellman key exchange protocol and the complete binary tree. Our protocol has less complexity of computation per group member by substituting many parts of exponentiation computations for multiplications. Consequently, each group member needs constant computations of exponentiation and multiplication regardless of the group size in the protocol and then it has less complexity of the computation than that of any other protocols.

  • As a result of the increased popularity of group oriented applications, the design of an efficient authenticated group key agreement protocol has received a lot of attention. Lee et al. proposed a tree-based group key agreement protocol, which applies a ternary key tree structure and pairing-based cryptography to the key agreement of Dynamic Peer Group. In their protocol, only the group sponsor knows all member's session random keys computes all blinded keys. In addition, when the group sponsor leaves a group, all nodes of the tree should be changed. In this paper, we present the modified protocol that has several sponsors. Since a secret value for each member isn't given to the group sponsor, the key renewing of our protocol is more secure and efficient than that of Lee et al.'s protocol in the previous case. Therefore, our protocol is suitable to Dynamic Peer Groups.

  • In MANET consisting of only mobile nodes, all nodes serve as routes. However, the dynamic topology due to frequent movement of nodes degrades routing performance and is also cause of many security vulnerabilities. Therefore, security must be applied to routing techniques that can influence the performance of MANET. In this paper, we propose a technique for efficiently responding to various routing attacks and safe data transmission through application of zone-key based security routing techniques. A zone-based network structure was used, and a management node that manages member nodes in each zone was used in the proposed technique. In addition, the damage from the attacking node was minimized by issuing a key to each node and applying this to a routing technique. The zone management node issues a key for encryption routing information and manages the issuance information. A member node that wants to transmit data encrypts routing in formation using a key issued from the zone management node, and then performs path discovery using this. The improved performance of the proposed technique was confirmed through a comparative experiment with the CBSR and ARNA technique, excellent performance was confirmed through experiments.

  • Purpose: This study aimed to identify research trends related to emotional leadership among nurse managers by conducting a systematic literature review and meta-analysis. This study sought to derive insights that could contribute to improving emotional leadership in nursing practice. Methods: A systematic review and meta-analysis were conducted according to the Preferred Reporting Items for Systematic Reviews and Meta-Analysis (PRISMA) and Meta-Analysis Of Observational Studies in Epidemiology (MOOSE) guidelines. Databases including PubMed, Cumulative Index to Nursing and Allied Health Literature, Scopus, Web of Science, Research Information Sharing Service, Koreanstudies Information Service System, Korean Medical Database, KoreaMed, ScienceON, and DBpia were searched to obtain papers published in English and Korean. Literature searches and screenings were conducted for the period December 1, 2023 to December 17, 2023. The effect size correlation (ESr) was calculated for each variable and the meta-analysis was performed using the statistical software SPSS 29.0, R 4.3.1. Results: Twenty-five (four personal, six job, and fifteen organizational) relevant variables were identified through the systematic review. The results of the meta-analysis showed that the total overall effect size was ESr = .33. Job satisfaction (ESr = .40) and leader-member exchange (ESr = .75) had the largest effect size among the job and organizational-related factors. Conclusion: Emotional leadership helps promote positive changes within organizations, improves organizational effectiveness, and increases member engagement and satisfaction. Therefore, it is considered an important strategic factor in improving organizational performance.

  • Societies are important sources of new information for users. However, most of these societies still rely on traditional, or rather ancient methods for gathering and servicing the information. Furthermore, most of the societies are trying to electrify processes such as managing members and paper submission as well as the process managing the information for service but are limited due to financial and technical reasons. Therefore, KISTI(Korea Institute of Science and Technology Information) has developed the ${\ulcorner}$KISTl-ACOMS (KISTI-Article Contribution Management System)${\lrcorner}$ as part of the national project for automating the process of processing academic information by societies, in order to convert journals published by academic societies in Korea into an electronic form and make them accessible on the Internet. This system has been developed in the year 2001 and has since been distributed to societies free of charge. The number of societies requesting the service has risen recently, which prompted us to take more recommendations of the societies that adopt this system into account in expanding and standardizing the area of service being provided by the system.

  • The environmental issues including domestic measures to protect public life or health are generally easy to bring the tension between the WTO and its member countries. The standard of review, whether de novo review, total deference, or somewhere in between, is largely important in the WTO's adjudicating mechanism because it is closely related to the appropriate balance of power between sovereign nations and the WTO: The multilateral trading regime, through the proper standard of review, could harmoniously operated without interest conflicts among the member countries and at the same time between the WTO and the member countries. Irrespective the important function of the standard of review in the WTO judicial system, applicable standard of review has not been established in the current SPS Agreement. Furthermore, the nature of the SPS Agreement related in scientific factors, such as scientific experiment, data and assessment prevents the WTO's panel from applying consistent standard of review. Considering the judicial demand for the moderate treatment of the case under the SPS Agreement, this paper explores appropriate standard of review applicable the SPS-related environmental measures, particularly, by analysing the recent SPS-related dispute, US-Hormones Suspension.

  • The purpose of this study is to empirically analyze the effects of characteristics of Leader (authoritarian disposition, procedural justice, job instability) on the organizational commitment of subordinates through abusive supervision and leader-member exchange(LMX). To this end, a survey was performed on the employees under the manager level in a large enterprise in Korea. The results of this study are as follows. First, the Hypothesis 1, 2, and 3 that the characteristics of leader (authoritarian disposition, procedural justice, job instability) will make effects on the organizational commitment of subordinates through abusive supervision were adopted. Second, in the hypotheses that the characteristics of leader (authoritarian disposition, procedural justice, job instability) will make effects on the organizational commitment of subordinates through LMX, Hypothesis 4 of authoritarian disposition, and Hypothesis 6 of job instability were rejected, while only Hypothesis 5 of procedural justice was adopted, as it made effects on the organizational commitment of subordinates through LMX. Third, the Hypothesis 7, 8, and 9 that the characteristics of leader (authoritarian disposition, procedural justice, job instability) will make effects on the organizational commitment of subordinates through abusive supervision and LMX were all adopted. This study is meaningful, in that it identified the structural relationship that the characteristics of leader make effects on the organizational commitment of subordinates through abusive supervision and LMX. It is expected that the results of this study can be used as base materials for new studies on abusive supervision which have been made in diversified ways in Korea and overseas.

  • Recently, owing to performance elevation of telecommunication technology, increase of wireless internet's subscriber and diffusion of wireless device, Interest about LBS (Location Based Service) which take advantage of user's location information and can receive information in concerning with user's location is increasing rapidly. So, MOMS (Moving Object Management System) that manage user's location information is required compulsorily to provide location base service. LBS of childhood such as service to find a friend need only current location, but to provide high-quality service in connection with Data Mining, CRM, We must be able to manage location information of past. In this paper, we design distributed manage system to insert and search Moving Object in a large amount. It has been consisted of CLIM (Current Location Information Manager), PLIM (Past-Location Information Manager) and BLIM (Distributed Location Information Manager). CLIM and PLIM prove performance of searching data by using spatiotemporal-index. DLIM distribute an enormous amount of location data to various database. Thus it keeps load-balance, regulates overload and manage a huge number of location information efficiently.
