Different countries around the world, using their traditional culture as a background, are promoting new changes and reformation in development and publicity method of cultural contents to promote national interests and to increase their competitiveness. Also, as the citizen's standard of living and quality of living goes up, various demands for the enjoyment of traditional culture goes up accordingly as well. As the cultural assets environment become more complicated and diverse, there is a need for systematic management and preservation plan. Keeping these viewpoints in mind, the geo-spatial information provision service using the web provides various forms of services such as satellite imagery, terrain, and 3D viewing, enabling the user to gain concrete spatial information on specific areas. The geo-spatial information using 3D modeling is done only in limited spaces because of construction expenses or difficulties in management and maintenance. In this thesis, I would like to propose Effective method for the GoogleEarth Uploading through simplification of 3D object for the publicity of traditional buildings and Cultural Resources and Tourist Attractions.

According to the rapid growth of high speed and precise industry, the application of synchronous motor has been increased. In the application fields, these fast dynamic response is of prime importance. In particular, since the PMLSM(Permanent Magnet Linear Synchronous Motor) has characteristics of high speed, high thrust, it has been used in high-performance servo drive. From these reasons, it is recently used for high precise position control, and machine tool. In this paper, a study of the sliding mode with VSS (Variable Structure System) design for a PMLSM is presented. For fast and precise motion control of PMLSM, the compensation of disturbance and parameter variation is necessary. Hence we eliminate the reaching phase use of VSS that is changed to switching function and vector control using the state observer. And we proposed to sliding mode control algorithm so that realize fast response without overshoot, disturbance and parameter variation.

To make service location protocol of IETF which is to be used in the wide area network to discover the location of desired service when computing resources are connected to the network, and to support simless connectivity between wired and wireless network in service viewpoint, to support the diversity trend of service agents in WIF, it needs to improve SLP, so as to add Liaison Agent and Forwarding Agent with FAAdvert message that is to communicate in between those entities. LA entity confirms the location of service located in wide area network, and FA transfers service information. The usage of existing messages such as SrvRqst, SrvRply, AttrRqst, AttrRply, DAAdvert, SrvReg, SrvAck, SrvDeReg is same as ever in wide area service network. The behaviors of improved protocol is modeled into petri-net and prove that it is free of deadlock and live-lock by execution of the model.

Ideals of beauty has expressed variously through the centuries and in different cultures. Each traditional 'togu' has it's own morphology (in the meaning of nonverval linguistic) as using various type of language in each cultural erea. Korean aesthetics on 'dogu'philosophy introduces a whole new set of basic concepts outside western aesthetic framework of beauty Most distinctive is the insistence on overcoming dichotomies, especially between cognition and emotion, (momism)body and mind, self and other, and individual and group. Several topics are particularly illuminating within aesthetics: furniture, calligraphy, traditional garments pose interesting challenging to the art/nature, inside/outside, ethics/desire dichotomies so crucial to moral and cultural context. aesthetics are equally deserving of philosophical scrutiny: the ways in which philosophy of 'dogu'and aesthetics are integrated with daily life, the emphasis on process or understanding context rather than product itself or product 'form'. Dogu did not separate daily life and aesthetics from understanding social context. Language of 'togu' also has own vocabulary and grammar. But we often cannot gain our persnol experience truthful beauty of togu until understand context of understanding. it would be immpossible to explain ,or to analize different way of thinkings and behaivor precisly without understanding same codes of language.

Korean Longitudinal Study of Ageing(KLoSA)', launched in 2006, has developed a research network with 'Health and Retirement Study(HRS, US),' Studies on Health and Retirement in Europe(SHARE, EU),' and 'English Longitudinal Study of Ageing(ELSA, UK)'and tried to construct a mega data library. The KLoSA team has designed their research with focusing on the following three points, in order to use KLoSA for international comparative studies. First, KLoSA shares the key research areas such as family structure, health, employment, income, asset, subjective expectations with the comparable studies. Second, KLoSA team has developed the instrument to reflect the Korean culture and institutions. They considered the institutional characteristics in public pension and health care system and in employment practices. They also counted the cultural conventions in family life such as financial management and care exchange, Finally, KLoSA tries to capture the psychological characteristics of the Korean elderly by making the measurement scales more understandable.

U-City has been promoted nation-wide by development of recent IT technology. This paper studied the concept of 3D-virtual city in order to realize the current Ubiquitous City(U-City) efficiently, and to manage all the RFID/USN monitoring data in the real U-City. 3D-Virtual City is the concept of the reproduction of real world U-City, for embodying Ubiquitous technology while using Digital map, satellite image, VRML(Virtual Reality Modeling Language). U&V-City is the four-dimensional future city that real-time wire/wireless communication network and 3D-web GIS shall be connected that massive database, intelligent service be perceived through employing EAI(External Authoring Interface) that provides HTML&JAVA, and interface for efficient removal/process of massive information/ service and also by employing GPS/LBS/Navigation in support of world-wide orientation concept, and RTLS(Real Time Location System).

보장조치 대상 원자력 시선에 대한 사찰 목적은 평화적 목적으로 사용되기 위한 시설 및 핵물질이 핵무기 생산 등의 비평화적 목적으로 전용되지 않았음을 확인하는 것이다. 이를 위하여 국제원자력기구에서는 보장조치 기준(IAEA Safeguards Criteria : 1991 - 1995)에 따라 적절한 검증 수단을 사용하여 핵물질의 형태 및 양, 시설의 운전기록 등에 대하여 보고된 내용과 실제 상황과의 일치성을 확인하고, 미신고된 핵활동이 없음을 확인하고 있다. 보장조치 측면에서 보면, 중수형원자로(CANDU)는 핵연료의 크기가 작고 운전중에 핵연료를 교체하는 방식(On Load Reactors)을 채택하고 있기 때문에 시설 내에서의 핵물질 이동이 매우 빈번하며, 사용후핵연료의 양 역시 경수형원자로에 비해 매우 많다. 따라서 중수형원자로에 대한 보장조치 사찰은 경수형원자로에 비해 사찰일수(최대허용사찰량 : 중수형원자로 45 인-일/년, 경수형원자로 15 인-일/년)가 훨씬 많고 보장조치 관련 장비 또한 매우 다양하다. 현재 운전 중인 월성 1호기에 이어 건설 중인 월성 2, 3, 4호기의 운전이 시작되면 중수형원자로에 대한 국제원자력기구 및 국가사찰 양이 급격히 늘어날 전망이다. 또한 월성 1호기의 경우 사용후핵연료 저장조의 용량 초과로 인한 건식저장고(Dry Canister)로의 이송이 1992년도부터 매년 실시되고 있으며, 이 기간 중에 이송 대상 핵연료의 검증 및 운반 중 전용을 방지하기 위한 추가적인 사찰이 수행됨으로써 많은 인력과 시간이 투입되고 있다. 또한 국제원자력기구에서 추진하고 있는 보장조치 강화 방안의 일환으로 현재 건설 중인 월성 2, 3, 4호기에 대해서는 월성 1호기에는 적용되지 않은 추가적인 보장조치 관련 장비의 설치가 고려되고 있다. 이에 따라 우리나라에서는 중수형원자로에 대한 국제 원자력기구의 사찰 기준 및 사찰 내용을 분석, 중수형원자로 보장조치 사찰에 대한 개선점을 도출하고, 후속기에 대해서 보다 효율적이고 효과적인 보장조치 방안을 적용토록 하여야 할 것이다.

The marketing system of non-timber forest products has been criticized as it mainly depends upon private local dealers, having too many steps between producers and consumers, we believe, which makes it less efficient. Meanwhile, there were only a few empirical studies of how they are delivered to consumers. In order to devise and implement targeted forest policies efficiently, it is quite necessary to understand the distribution channel of them. We analyzed the distribution channel of chestnut, bitter persimmon, oak mushroom, and wild greens by data analysis, field and phone survey, and then drew an implication for improving the marketing system. First of all, the number of middle step has to be reduced and the direct transaction has to be expended. In addition, we need to have more active involvement of Forest cooperative in production sites, adding values by processing, and the upgrade of current marketing centers of non-timber forest products, which have been launched since 2004 by Korea Forest Service.

The most important thing for the national GIS development is considered to be the standardization, especially the development of the standard coding scheme for the GIS features and attributes. The comparative study on those of the several international transfer standard is, therefore, very meaningful. In this paper we analyzed the features and attributes coding catalogue for the three different exchange standards; SDTS, DIGEST and SP-57. And also the new coding scheme is proposed as the unified standard frame to be used for all the GIS related application and the digital product.
