The steel bars account for a high percentage of material costs for the current construction projects. At the present time, most of the construction projects for the factories of thin-film transistor liquid crystal display (TFT-LCD) complete the transactions of steel bars when the suppliers ship the steel bars to the temporary storage/processing sites. This paper applies the buy-in concept in the Theory of Constraint (TOC) on the supply chain of steel bars. In this study, suppliers are required to establish warehouses at the construction sites and complete the transactions when the formed and processed steel bars are shipped into the factory sites. The aim is to find a win-win solution to meet with the expectations from constructors as they hope that there is no need to build up inventories but supply is ready at any time. Also, this paper compares and analyzes the traditional supply/inventory model of steel bars and the Demand-Pull (D-P) model under the TOC framework. It is proved that Vendor Management Inventory (VMI) in the D-P model is able to more effectively manage steel bars as a material.

Rapid prototyping(RP) has been used for design verification and proto sample or mold manufacturing. Many RP systems have been introduced into the market during the past 15 years. However, until now, the systems have used mainly for external physical models (mono function), and have the basic but critical limitation of one material on one stage (mono material). To overcome the limitations of mono-material and mono-function of conventional. RP systems, the concept of Functional Phototype Development (FPD) is newly proposed in this paper FPD provides the necessary prototype functions such as mechanical, optical, chemical and electrical properties in order to meet the broad requirements of the industry. The paper illustrates the representative achievements of electronic components such as the multi-layer printed circuit board(MLB). Experimental results demonstrate that FPD has great potential applied to broad industrial uses and that It Will be a powerful tool in the neat future.

This paper presents how Korea succeeded in developing an indigenous nuclear power plant model over fifty years. Long-lasting national R&D for technical progress and the Korean government for managerial process were the two pillars in the build-up of indigenous Nuclear Power Plant (NPP) technological capabilities. The concept of technological capabilities is used to examine its evolutionary process with a qualitative and longitudinal approach. The government had a developing country ambition to formulate a strategic plan for technical self-reliance on nuclear power plant while establishing the country’s institutions and organization structure for the plan. Under the government leadership, it was national R&D that led to the resolution of a good number of technological problems, efficiently, by absorbing imported technologies and effectively adapting them to local circumstances.

School is a basic and the most fundamental facility of city planning just like other basic public facilities including the village office. Every plan is established on the basis of school. However, the problems such as the population reduction resulting from the nuclear family-zation and low birth rate, employment and welfare of the aged people resulting from "the old aged society", and the infant nursing and education resulting from a rapid increase of the working couples become notable and accordingly more requirements are being made. Reflecting this trend, the concept and operation system should be changed. Up to now, the BTL projects of the educational facilities are gaining a reputation of being efficient in terms of national budget running, but at the same time receiving negative reputation in terms of budget saving under the civil creativity and efficiency. Through upgrading the private sector investment projects into the BTO+BTL system and further into the BTO(Build Transfer Operate), we can accomplish the original goals of the private sector investment projects, and can make the education budget operation more efficient, and can greatly improve the education environments. However, we should not underestimate in this process that these facilities should not negatively affect the education environments. In any situation, the owners of schools are students.

Treatment of schizophrenia is one of the most challenging areas in the field of psychiatry. There has been much improvement in psycho-pharmacotherapy, and at present, psycho-pharmacotherapy along with milieu therapy and social rehabilitation is the standard first-line treatment for schizophrenia. Healing environment, a concept which has arisen from the architectural field, has similarities in meaning to milieu therapy in psychiatry. In other words, healing environment may be an encountering point between psychiatry and architecture. In this encountering, each field can understand each other and expand its concept to aid the treatment of schizophrenia and to plan the build-up of the entire environment considering its social and psychological effects. In this paper, we aim to establish the basic concept of healing environment to alleviate the psychopathologies in schizophrenic patients. We worked under the premise that physical setting affects human behavior and mind, and that physical setting should play a role as a medium with therapeutic potential for patients with medical problems. The aims of this paper are as follows. First, theoretical discussion of the concept and the constructs of healing environment : second, understanding of the schizophrenic symptoms that may be affected by supporting environment : and third, discussion of supporting environment that may alleviate the symptoms of schizophrenia.

The concept of jigs and fixtures makes it possible to build fixtures that can be dismantled at project completion. Since this concept is modular, it is not limited to any particular unit shapes or sizes. Various standards assure that each component assemble rapidly, to get precision and accuracy. Best suited for prototype and low volume production, as well as, start-up or zero-runs, it can also substitute for damaged dedicated fixtures to minimize down-time. It need to do DB for each part by Pro/Engineer and to assemble before manufacturing. In the future will assemble each of clamping and position parts by automation.

The objectives of this study are to build up the concept of Environment-Oriented Land Suitability Assessment(EOLSA) and to develop the EOLSA mapping system by applying the EOLSA criteria to the case study area. In order to draw out the EOLSA critera, this study adopted the Delphi method including the experts' awareness survey to urban planners as well as environmental researchers in May and June 2001. As a result, the concept of EPLSA was defined as a process of land use planning to scientifically assess the physical and environmental value of land and to classify conservation aptitude into several grades for the sustainable management of environmental resources. With an outcome of applying the EOLSA criteria with five degrees to the Seoul Metropolitan Area (SMA), Grade I, indicating the highest conservation value, accounted for 57.76% of the SMA. Then, Grade II reached up to 15.06%, Grade III 3.12%, Grade IV 15.92%, and Grade V, the lowest conservation value, 7.99% respectively. And also, the case analysis showed that the share of Grade I area was the highest in Gapyong county and Yangpyong county, Pochon county, Yeonchon county, Yongin city in the order and the lowest in Kwangmyong city, Osan city, Kunpo city, Kuri city, and Buchon city.

Objectives : Acquiring information from symptoms is one of the important method to gain clinically available information in korean medicine. Therefore, up to now, study of symptom terms was frequently implemented in promotion of various information project. In data extraction methods using symptom information from DB, information search using synonym and method using ontology is studied and utilized. However, considering concept of symptom has essential information of appeared body area and phenomenon we think that extending synonym and ontology relationship in symptom terms can be useful for search and set to this study. Methods : We collect terms relevant to human body area and structure described in Donguibogam. Synonymous relationship between collected terms is organized. Relationship between collected terms is build to human-body-knowledge table which has form of Concept+Relation+Concept. Type of relationship is limited on a range of expressing content about parts of human body. Result & Conclusion : Search condition is generated automatically using relationship of the upper area in knowledge table contents. Information of next and previous acupuncture point, upper and lower acupuncture point, left and right acupuncture point can be searched using information of acupuncture point location, order, relative position in area, direction in knowledge table contents.

The aim of this paper is to analyze China's naval strengthening and threat reflected in submarines, aircraft, destroyers and missile capabilities and US Navy's counter-forces. China is strengthening its naval forces in accordance with its three-step naval force build-up plan, and the introduction of Russian destroyers and submarines is a foothold for China's naval enforcement. The Chinese Navy also converted the concept of the First-Second Island Chain Defense, which it had already maintained, to the concept of maritime layer defense. Currently, the Chinese Navy maintains the concept of a Three-Maritime Layer Defense which includes the South China Sea, where artificial islands are being built by China, in the First Layer Defense and the East China Sea in the Third Layer Defense. Along with the advancement of Chinese Navy's submarines, surface vessels and aircraft's operational capabilities, ballistic and cruise missile capabilities become a major threat to the US Navy. If a crisis occurs in the East China Sea or in the Taiwan Waters, the US Navy will face more difficulties in employing the Carrier Strike Group to manage the crisis. Meanwhile, if a crisis occurs on the Korean Peninsula, it will be a burden to dispatch Carrier Strike GroupS to the East and West Seas of the Korean Peninsula. For the stable future, the US Navy should develop a strategy to respond more effectively to the Chinese Navy, which is challenging new maritime supremacy in East Asia.
