The world of today faces a radical change, a new revolution, by the spread of the Internet. It is used not only for advertising but also for the exclusive rights in the field of information and communication, in add to the way of developing everyday our lives with world news, home-shopping, on-line education and so on. Actually, since the Internet Domain's Name(IDN) is unique over the world, the individual and the companies which provide information through the Internet have a keen competition to make a good IDN to memorize and organize all available information provided them. As a result, there are an increasing number of the cases where one company files suit against another for the validity of it's IDN so the policy to arbitrate and solute the cases is required. This paper is going to introduce the structure and the system of management for IDN. It will also discuss the efficient management of IDN, various case analysis of the dispute restraint and solutions, and the movement of improving the management procedure of IDN in WIPO. So we suggest to examine common disputes among IDN uses and solution methods for future problem at EC times. Therefore we have to establish the dispute solution system. Here are the two methods : one is that to establish a dispute solution organization. This organization which can conduct the new dispute solution procedure differs from the existing legislation system. The other is that to establish a dispute solution procedure i.e. the various dispute solution procedure for efficient dispute solution : council, inspection, mediation and arbitration. This procedure is conducted on-line due to features of the IDN disputes, also along with the current legislation system and the International dispute solution procedure. Because there is possibility the IDN disputes usually are connected with other countries. As there is no specific disputes solution procedure so far, we have to wait while development occurs that also striving to be coherent with and between the domestic and International solution procedure by helping to establish the International dispute solution procedure.

Objectives : The purpose of this study was to evaluate the effect of social skills training (SST) for children in two different community settings, an elementary school and a child community center. Methods : Two separate groups of 15 children (10 boys and 5 girls) and 13 children (4 boys and 9 girls) participated in a SST program twice per week at an elementary school and a child community center, respectively. Age range of participants was from 8 to 10 years. Sixty-minute-long sessions of SST were continued twice per week for 4 weeks. Korean-Child Behavior Checklist (K-CBCL), Conner's Rating Scales, Korean-Attention-Deficit Hyperactivity Disorder Rating Scale (K-ARS), Social Skills Rating System (SSRS), and Matson's Evaluation of Social Skills with Youngsters (MESSY) were evaluated by their parents before and after the SST program. Results : Pre-and-post analysis of SST indicated no significant statistical differences in the elementary school group. However, the child community center group showed significantly increased scores for total social ability (p<.05) and decreased scores for attention problem (p<.05) on the K-CBCL. In addition, scores of MESSY were significantly increased (p<.05). These differences between the two groups were still significant after controlling pre-SST scores ; and difference of SST scores between the two groups disappeared after SST. Conclusion : Results suggest that SST in the community setting is an effective tool for prevention of social deficits and problems in attention by promoting social function and attention.

Due to the advantages of Internet, many teachers use Internet as an educational tool and due to the computerized works in schools, the usages of the Internet increase. However, because of the openness of the Internet, the sensitive data of an organization are exposed to outsiders and the Internet-based working has some problems such as the corruptions of instructional data or on-line assessment results. The need for protecting a school network from outsiders increases but the school networks with firewalls rarely exist. In this paper, in order to solve the security problem of a school network, we construct a hybrid firewall for school networks. In addition, we implement a graphical user interface for teachers to set up the access control rules of a hybrid firewall easily. The interface also provides the facilities such as log analysis, a real-time monitor for network traffics, and the statistic on traffics.

With rapid increase in the number of web documents, the problem of information overload in Internet search is growing seriously. In order to improve web search results, previous research studies employed user queries/preferred words and the number of links in the web documents. In this study, performance of the search results exploiting these two criteria is examined and other preference criteria for web documents are analyzed. Experimental results show that personalized web search results employing queries and preferred words yield up to 1.7 times better performance over the current search engine and that the search results using the number of links gives up to 1.3 times better performance. Although it is found that the first of the user's preference criteria for web documents is the contents of the document, readability and images in the document are also given a large weight. Therefore, performance of web search personalization algorithms will be greatly improved if they incorporate objective data reflecting each user's characteristics in addition to the number of queries and preferred words.

This paper analyse current interpretation of the "causal link" that in particular, focuses principally on the so-called "non-attribution" requirement of Article 4.2(b) of the Safeguards Agreement. The safeguard measures are justified as a temporary economic adjustment to harm that is caused by an increase in imports. The problem with this justification is that there are other kinds of economic forces that may injure domestic industries, such as changes in consumer tastes, government spending or a lack thereof, and economic downturns. These problems do not justify government-imposed remedies. When factors therefore other than increased imports are causing injury to the domestic industry at the same time, such injury shall not be attributed to increased imports. The Appellate Body stressed that a contribution of third-party imports to the existence of serious injury must be sufficiently clear as to establish the existence of the causal link required, it found that Article 4.2(b) does not suggest that increased imports be the sole cause of the serious injury, or that other factors causing injury must be excluded from the determination of serious injury. The interest in separation is to ensure that a measure is not applied to remedy harm not caused by imports, but this basic point assumes that the harm is distinguishable in the first place. It also assumes that the safeguard is designed to respond to harm caused by imports. In fact safeguards were never intended to respond to this kind of unfair trade, but rather to provide whatever emergency relief might assist an ailing domestic industry if imports happened to be a part of that injury. The Appellate Body's insistence in breaking cause and effect down to minutia in the non-attribution analysis seems to be so overly intricate that it conflicts with it's broader focus on evaluating factors that effect harm on the industry as a whole.

This study presents a FZOGP(fuzzified zero-one goal programming) model and a DHP (Delphic Hierarchy Process) that can be used to help information systems(IS) managers decides which IS projects should be selected. Delphic method is conducted prior to AHP so that not only can the objectives to be considered in analysis be determined, but the opinions of all decision makers can also be incorporated in problem formulation. While the DHP provides an ideal ranking process for the selection of IS Projects, it does not consider real constraints that exists in decision making process. Then this study intends to show how the DHP can be used to establish a priority structure for use within a FZOGP model. The advantages of FZOGP model are as follows: the imprecise aspiration level for each objective can be considered in FZOGP model. And, the common features between the new FZOGP and the GP models are that the objective functions in both models are minimized and the structure of their formulations are the same.

This paper propose a new wireless multi-hop routing protocol that takes the hierarchical mesh of the hybrid WMN into account. WMN that is possible to provide various applications of wireless networks still has many open issues that should be solved despite the studies carried out over a decade. Especially, in routing protocol area, a problem degrading the routing efficiency by applying one of the routing protocols, which are designed for the MANET, to the hybrid WMN be solved above all. For the improvement of the routing performance, both good routing protocol and metric are essential. However, the recent studies are only concentrated in routing metric by use of the cross-layer design. Therefore, this paper is dedicated to the routing protocol that is essential for the performance of the routing but needed more studies. The proposed protocol in this paper is reactive, and designed to reorganize the hybrid WMN with several pseudo domains, and carry out domain-based route decision. By the simulation result for the performance analysis of the proposed protocol, the average delay for the route decision was decreased by 43% compared to AODV that is the typical reactive protocol.

Context dependent fusion (CDF) is a fusion algorithm that combines multiple outputs from different classifiers to achieve better performance. CDF tries to divide the problem context into several homogeneous sub-contexts and to fuse data locally with respect to each sub-context. CDF showed better performance than existing methods, however, it is sensitive to noise due to the large number of parameters optimized and the innate linearity limits the application of CDF. In this paper, a variant of CDF using support vector machines (SVMs) for fusion and kernel principal component analysis (K-PCA) for context extraction is proposed to solve the problems in CDF, named CDF-SVM. Kernel PCA can shape irregular clusters including elliptical ones through the non-linear kernel transformation and SVM can draw a non-linear decision boundary. Regularization terms is also included in the objective function of CDF-SVM to mitigate the noise sensitivity in CDF. CDF-SVM showed better performance than CDF and its variants, which is demonstrated through the experiments with a landmine data set.

The life of components under high thermal load is typically shorter than other components. The turbopump turbine of liquid rocket is operated under these environments like high temperature and high centrifugal dorce due to high rotating velocity during operating time. These conditions may often cause low-cycle fatigue problem in the turbopump turbine. First of all, to analyze heat stress, ABAQUS/CAE is used and Coffin-manson's equation is used to consider elasticity and plasticity strain. S.W.T's method is used to consider the mean stress effect, using strain history, low-cycle fatigue analysis is done for turbopump turbine which may have FCL(fracture critical location). In this paper, strain life method is applied to analyze low-cycle fatigue.

The NHPP software reliability models for failure analysis can have, in the literature, exhibit either constant, monotonic increasing or monotonic decreasing failure occurrence rates per fault. In this paper, finite failure NHPP models that assuming the expected value of the defect and infinite failures NHPP models that repairing software failure point in time reflects the situation, were presented for comparing property. Commonly used in the field of software reliability based on Rayleigh distribution software reliability model finite failures and infinite failures were presented for comparison problem. As a result, infinite fault model is effectively finite fault models, respectively. The parameters estimation using maximum likelihood estimation was conducted. In this research, can be able to help software developers for considering software failure property some extent.
