The purpose of this study was to investigate the impact of negotiation in Argument-Based Inquiry on students’ claim and evidence. A total of 126 first grade middle school students participated in this study and they performed five Argument-Based Inquiry (ABI) programs for one academic a year. To investigate the process of generating claim and evidence through the ABI, we interviewed students after they completed five ABI activities. The study findings showed that students ability to make claim and evidence improved as they progressed from individual activity to group activity in ABI activity and as ABI activities. The results also showed that students generated high level of claim and evidence through internal and external negotiation in ABI programs.

This study examined the role of contextual knowledge in cross-cultural communication between non-native speakers on an interactive web with a bulletin board system through which college students of English at Japanese and Korean universities interacted with each other discussing the topics of local and global issues. The study investigated the influence of students' relative contextual knowledge on active participation in interactions and discussed the results focusing on the use of discourse strategies for meaning negotiation. The study argues that in interactions even between non-native speakers with limited proficiency, contextual knowledge in the topic under discussion affects the degree to which they accommodate to each other during communication and suggests that the focus of teaching English as a foreign language also should be given to what kind of contextual knowledge students need to obtain and how to express it rather than what level of proficiency in English they need to acquire.

Local opposition and protest constitute single greatest hurdle to the siting of locally unwanted land uses(LULUs), especially siting of high-level radioactive disposal not only throughout Korea but also throughout the industrialized world. It can be attributed mainly to the NIMBYism, equity problem, and lack of participation. These problems are arisen from rational planning process which emphasizes instrumental rationality. But planning is a value-laden political activity, in which substantive rationality is central. To achieve this goals, we need a sound planning process for siting LULUs, which should improve the ability of citizens to influence the decisions that affects them. By a sound planning process, we mean one that is open to citizen input and contains accurate and complete information. In other word, the public is also part of the goal setting process and, as the information and analyses developed by the planners are evaluated by the public, strategies for solutions can be developed through consensus-building. This method is called as a co-operative siting process, and must be structured in order to arrive at publicly acceptable decisions. The followings are decided by consensus-building method. 1. Negotiation will be held? 2. What is the benefits and risks of negotiation? 3. What are solutions when collisions between national interests and local ones come into? 4. What are the agendas? 5. What is the community' role in site selection? 6. Are there incentives to negotiation. 7. Who are the parties to the negotiation? 8. Who will represent the community? 9. What groundwork of negotiation is set up? 10. How do we assure that the community access to information and expert? 11. What happens if negotiation is failed? 12. Is it necessary to trust each other in negotiations? 13. Is a mediator needed in negotiations?

This study estimated the causal relationship among leisure identity salience (LIS), leisure constraints negotiation (LCN), and intentions to participate in leisure activity (IPLA). For this, we estimated structural equation models controlled by leisure constraints, and we used data collected from 296 college students residing in Seoul and Kyoung-gi providence. The following was obtained. First, for both groups with high and low levels of leisure constraints, LIS positively caused LCN, and this became more evident for the group with high level of leisure constraint. Second, for the group with low level of leisure constraints, LIS positively and directly caused IPLA, whereas this causal relationship could not observed from the group with high level of leisure constraints. Nevertheless, it indirectly and positively caused IPLA though LCN for the same group. This implies that the mediative role of LCN became more important as the level of leisure constraints became more restrictive. Further, we separately showed that the role of LIS was important in the process of LCN.

Since people have come to access more and more information about products with the proliferation of the Internet, more and more customer-to-customer e-marketplaces are being introduced with rapidly increasing transaction volumes. As the role of customer-to-customer electronic commerce has become increasingly regarded as vital to the economy, much research has delved into developing intelligent agent systems to efficiently support customer-to-customer electronic commerce. Most of this research, however, has focused only on supporting simple negotiation for the price of common goods along the time span. To expand the negotiation object to the differentiated goods, the customer must be allowed to negotiate over multi-at-tributes of the product besides the price, including the attributes related to the transaction activity itself, such as delivery time and payment method. To satisfy this requirement, we propose an agent marketplace for differentiated goods where the agent of a customer can negotiate not only the price but also the various attributes of the product and the transaction in order to achieve a better utility level for both buyer and seller. The formal protocol and the architecture issues to support the proposed e-marketplace and agents are also addressed.

Purpose: This study was done to identify the level of Internet addiction among adolescents, and to examine factors affecting Internet addiction in adolescents. Method: The participants in were 475 high school students. Data were analyzed using multiple regression analysis to examine the factors affecting Internet addiction in adolescents. Result: The overall Internet addiction scale score was 63.83(±20.48). The differences of Internet addiction according to student characteristics were found to be significant for sex and grade. The level of Internet addiction was positively related to the level of impulsiveness and depression. The level of Internet addiction was negatively related to the level of social support. Factors such as impulsiveness and social support were examined as significant factors predicting Internet addiction in adolescents. Conclusion: Based upon these findings, factors affecting Internet addiction in adolescents include impulsiveness and social support. The findings provide further justification for interventions targeting key factors that influence Internet addiction in adolescents in addition to providing adolescents with necessary communication, negotiation and other life skills.

In this paper, we propose FAS model for establishing trust based on digital certificates in Grid security framework. The existing RBAC(Role Based Access Control) model is extended to provide permissions depending on the users‘ roles. The FAS model is designed for a system independent integrated Grid security by detailing and extending the fundamental architecture of user, role, and permission. FAS decides each user’s role, allocates access right, and publishes attribute certificate. FAS is composed of three modules: RDM, PCM, and CCM. The RDM decides roles of the user during trust negotiation process and improves the existing low level Grid security in which every single user maps a single shared local name. Both PCM and CCM confirm the capability of the user based on various policies that can restrict priority of the different user groups and roles. We have analyzed the FAS strategy with the complexity of the policy graph-based strategy. In particular, we focused on the algorithm for constructing the policy graph. As a result, the total running time was significantly reduced.

Rapid growth of the IT industry has led to significant energy consumption in the last decade. Data centers swallow an enormous amount of electrical energy and have high operating costs and carbon dioxide excretions. In response to this, the dynamic consolidation of virtual machines (VMs) allows for efficient resource management and reduces power consumption through the live migration of VMs in the hosts. Moreover, each client typically has a service level agreement (SLA), this leads to stipulations in dealing with energy-performance trade-offs, as aggressive consolidation may lead to performance degradation beyond the negotiation. In this paper we propose a heuristic based resource allocation of VM selection and a VM allocation approach that aims to minimize the total energy consumption and operating costs while meeting the client-level SLA. Our experiment results demonstrate significant enhancements in cloud providers' profit and energy savings while improving the SLA at a certain level.

Free trade agreements have fast grown into a global phenomenon and their impact and repercussions are felt more strongly everyday. Korea, joining this large trend of the global economy, is currently pressing ahead with its negotiation rounds for FTA. In this paper, we focus on the e-commerce sector affected by the Korea-Singapore FTA, and the main issues and the future countermeasure directions of e-commerce on FTA has been analyzed. In conclusion, FTA is not an option even though there are still many remaining issues to be discussed regarding its effects. We identified countries excluding themselves from FTA are losing international competitiveness, and moreover, the losing competitiveness will end up more serious problems since the importance of FTA is especially high for e-commerce, as e-commerce accounts for a growing share of international trade. This paper also discusses the far-reaching potential consequences of the content of an international agreement at a government-to-government level on the economy and industry of a country by presenting past examples from. Korea, and recommends that policy-makers should exercise extreme vigilance in their negotiation of terms and conditions for FTA.

The purpose of this study is to find what factors are directly related to the delay of public projects, usually going beyond the planned deadline and budget. From a series of System Dynamics simulation works applied to the Cheongju Cremation Project, the research finds that the negative externalities originated from the adjacent location of the LULU(locally unwanted land use) facilities have exerted significant influence on dynamic perceptions of key stakeholders, typically resulting in project delay. As shown repeated experiments, the proposed negotiation-based models would produce relatively higher planning performance level than the typical approaches hinged on the administrative-expediency tactics. Even though the former may require more human and material resources in the very beginning stage, as they have to deal with diverse grievances raised by major stake-holders, most of them would bound for strengthening reinforcing loops within the complex structure. These results also imply that negotiation or consensus-building approaches would enhance mutual agreement among stake-holders, upgrading the overall quality of project management.
