In this paper we present 3-D Navigation View, a three-dimensional visualization of indoor environment which serves as an intuitive and unified user interface for our developed indoor location tracking system via Virtual Reality Modeling Language (VRML) in web environment. The extracted user's spatial information from indoor location tracking system was further processed to facilitate the location indication in virtual 3-D indoor environment based on his location in physical world. External Authoring Interface (EAI) provided by VRML enables the integration of interactive 3-D graphics into web and direct communication with the encapsulated Java applet to update position and viewpoint of user periodically in 3-D indoor environment. As any web browser with VRML viewer plug-in is able to run the platform independent 3-D Navigation View, specialized and expensive hardware or software can be disregarded.

Northeast Asian economies have achieved high levels of growth due to a stable economic environments and economic policy reforms for free trade. As Northeast Asia has been risen as big bloc in the world and in the future in case free trade agreement could be concluded, trade volume could be increased dramatically. And it is evident that disputes will be increased in Northeast Asian economic bloc. Arbitration must be popular in resolving international commercial disputes in Northeast Asian bloc in order to increase the volume of intra-trade in the bloc. Through arbitration, the parties can have full autonomy and can resolve disputes independently, impartially and without delay. But in order for the parties to make use of arbitration in the bloc, they must be fully aware of the arbitration laws of Northeast Asian nations in view of the similarity and difference of the laws. Therefore, this paper deals with arbitral award in Northeast Asian Nations' arbitration laws in view of comparative law.

W3C(World Wide Web Consortium)가 XML(eXtensible Markup Language)을 차세대 웹 문서 표준으로 제안하면서 많은 응용에서 XML을 사용하려는 다양한 연구가 진행되고 있다. 뷰는 이질적인(heterogeneous) 데이터의 통합 및 여과(filtering) 기능을 통해서 사용자가 요구하는 데이터를 제공한다. 뷰의 구현 기법 중에서 실체 뷰(materialized view)는 뷰의 내용을 직접 저장하는 기법으로서, 사용자의 질의에 빠른 응답시간을 제공할 수 있다. 그러나 실체 뷰는 하부 데이터베이스가 변경되었을 경우에 일관성을 유지해야 하는 오버헤드가 있다. XML은 문서의 구조정보를 나타낼 수 있으므로 기존의 관계 데이터베이스와 객체지향 데이터베이스 등에서 연구되었던 실체 뷰 관리 기법과는 다른 XML 실체 뷰 관리 기법이 요구된다. 본 논문에서는 XML 문서를 대상으로 XML 실체 뷰를 지원하고, 데이터베이스에 저장된 XML 문서가 수정되었을 경우에 XML 실체 뷰에 대해 점진적 갱신(incremental refresh)을 지원하는 XML 실체 뷰 관리 프레임워크(framework)를 제안하였다.

At this point, the Pan-Korea Grand Waterway (PKGW) has negative views and various complicated problems, but the government chose PKGW as important project for having a benefit in physical distribution, tourism, aggregate sale and new employment as well as in view of disaster prevention, flood control, irrigation. The government makes special laws for PKGW in evaluating environment effect and the safety of existing facilities and considers countermeasures for the rehabilitation, movement and redevelopment of facilities by related company and specialist. From analyzing and investigating the collective results in detail and in stages, the PKGW is the best choice by which korea engineers can hand over pleasant and beautiful korea to next generation in world.

The purpose of this essay is to review family ethics and child rearing reflected in WonBuddism and to suggest hypothetical model of family ethics and child rearing appropriate to modern society. WonBuddist family ethics hasits roots in the concept of "Grace" specifically, the essence of all relationships in the world as characterized by "Grace". WonBuddist family ethics based on this world view emphasizes mutual support, harmony and service for the public. The purpose of WonBuddist child rearing is to bring up children who recognize the world order mention above while, at the same time, developing the capacity to support oneself, ultimately resulting in individuals who are balanced both morally and practically. A WonBuddist model of family ethics and child rearing appropriate to modern society includes: (1) the concept of "Grace as a principle" for the restoration of essential humanity, (2) the principle of "mutual support" and "essential humanity" for the restoration of the feeling of family community (i.e., the cohesion of the family), and (3) the moral principle, "capacity for self support and public service" as a way of moderating the family oriented value system.

This paper deals with the question whether the metaphysical dialetheism is a persuasive view or not. That is, the purpose of this paper is to criticize the metaphysical dialetheism by answering three questions, whether the dialetheism is compatible with the correspondence theory of truth, whether there is an observable contradiction, finally what the status of LNC is. In conclusion, it is argued that dialetheism is incompatible with the correspondence theory of truth, because it results in trivialism to suppose that two views are compatible. It is also claimed that LNC should be understood as the principle of exclusion which constrains the structure of the world and that the real world is consistent. Therefore, there is no observable contradiction in the world and the metaphysical dialetheism is not persuasive.

Services could move over the world where they want to go. Especially, travel services shared 29.4 percent of total world exports, 625 billion dollars in 2004 (WTO, 2005). Tourism is a very important sector in service trade in the world. Of developing countries, Korea has been experiencing remarkable development in female outbound travel market since the complete liberalization on overseas travels in 1989, with about 3.85 million travelers in 2005, 2,000 percent growth rate over 1988. It means woman's social status has been increasing in Korea. Especially, in the study young housekeepers, solely office ladies, and college students were described as very important market segments in Korean woman outbound travel market. They were not only major decision makers, but also executors because of both enough economic power and social status improvement on small sized family. This study indicated that woman outbound travel market gets larger because their buying power and status are going to go improved in Korean social system. It is recommended that marketers be worth watching Korean woman travellers as a major target market through continuos observation and analysis.

In conventional thermodynamics, energy is regarded as a physical quantity transferring from one system to another, but in present study, the real energy is regarded as a physical quantity coming out from one interaction and absorbing into another interaction between two systems. To reconstruct thermodynamics with such a point of view, available work is distinguished from half work in conventional work concepts, and a special space named reversible world is proposed in which every process is reversible and the only measurable quantity is available work and just the equality between the intensities of two systems can be verified. As results, thermodynamic laws are arranged into two principles in the reversible world-conservations of energy elements and conservation of available energy. It means the exsistences of state properties corresponding to transferring energy elements and the available work. The former are extensive properties and the later is named potential work which is a property of the composite system and a kind of mathematical distance. The conventional available energy (exergy) and internal energy can be explained as the special cases of potential work, and the conventional first law of thermodynamics can be derived from the principle of the conservation of available energy. With these new concepts, the description of thermodynamic processes is more comprehensive. The second law of thermodynamics is no longer needed in the reversible world.

I try to formalize the system of modal logic and interpret it in view of constructivism through this study. As to the meaning of a sentence, as we saw, Frege endorsed extensions in view of the fact that they are enough to provide for a compositional account for truth, in particular that (1) the assignment of extensions to expressions is compositional ; (2) the assignment of extensions to sentences coincides with the assignment of truth values. But nobody would be willing to admit that a truth value is what a sentence means and that consequently all true sentences are synonymous. So, if what we are after is meaning in the intuitive sense, then extensions would not do. This consideration has later become the point of departure of modal and intensional semantics. So, it is clear that the language of modal logic do not allow for an extensional interpretation. ${\square}$ is syntactically on a par with ${\vdash}$, hence within the extensional framework it would have to denote a unary truth function. This means that if modal logic is to be interpreted, we need a semantics which is not extensional. The first attempt to build a feasible intensional semantics was presented by Saul Kripke. He came to the conclusion that we must let sentences denote not truth values, but rather subsets of a given set. He called elements of the underlying set possible world. Hence each sentence is taken to denote the set of those possible world in which it is true. This lets us explicate necessity as 'truth in every possible world' and possibility as 'truth in at least one possible world'. But it is clear that the system of modal logic is not only an enlargement of propositional logic, as long as the former contains the new symbols, but that it is of an other nature. In fact, the modal logic is intensional, in that the operators do not determine the functions of truth any more. But this new element is not given a priori, but a posteriori from construction by logicist.

The world-view of a period or a society refers to the way it conceives of the order and governing principles of the universe. The ad and outcome of the crealive process of a designer reflect his or her world-view or value system. Contemporary students of design seem to find the traditional approach to art based upon the Euclidean logic rather redudive and confining and are trying to develop a new way of thinking and methodology, a new frame of reference. In this study, I am offering the chaos- and fractal theory, concepts drawn from science, as a new anchoring point for design. This approach makes use of the concept of chaos as the basis of a new, open system that enables a designer to find and generate numerous visual possibilities immanent in chaos. Likewise. fractal geometry is offering new concepts and vocabularies for the study of physical universe and design thinking, as well as bridging the gap between science and art. The number of structural possibilities fractal theory generates for environmental design seems to be virtually unlimiLl'd. In fine. this study places a great emphasis on the new approaches t() the environment we inhabit. which I hope will contribute to generating a greater number of creative possibililil:s for environmental design.
