Since Modern Movement flexibility has been one of the most attractive words in architecture. However, "overprovision first, division later" has been the most prevailing design method for spatial flexibility, and many of buildings designed for flexible use are practically quite inflexible due to insufficient building systems or/and irresponsible planning. There have been two dominant strategies to achieve architectural flexibility: multi-functionality and polyvalence. These two approaches, which point contradictory directions, actually reflect the difficulty in providing a proper form of architectural flexibility. Multi-functionality can afford changeable environments with satisfying spatial conditions; however it lacks tolerance to accommodate other uses but intended functions by architects. Meanwhile, flexibility by a polyvalent form relies on the vague anticipation of user's various interpretations. In this study by looking up these two different standpoints and historical precedents flexibility in architecture is carefully scrutinized focused on the contradiction, and as an alternative for architectural flexibility contextual relations is proposed. Unlike both multi-functionality and polyvalence, which produce flexibility by changing its own properties, manipulating contextual relations infuses flexibility into space by changing the properties of a building, not of its individual room. By using this contextual relations method, a community-centered school in Manhattan, NY, which was in danger of being closed because of its academic failure, is represented as a flexible space.

The purpose of this study is to examine Japonica rice farming of China. Asian rice is divided into Japonica and Indica species. Japonica rice represents only less than 20% of Chinese rice output, but it can compete with Korea rice in both price and quality. The rise of income level has expanded the scale of production of Japonica rice in China. China’s adhesion to the World Trade Organization (WTO) has forced Chinese policy makers to face their obligations and responsibilities such as abolishing subsidies on agricultural exports. But being member of the WTO entry also helps China exercise and enhance its influential place in the global economy. Because of geographical proximity and the fact that Korea is ranked second among countries with which China still has a trade deficit, China may seek and plead for an opening of the protected Korean rice market to stabilize prices and prevent excess supply of Chinese rice. Though Korean rice farmers feel that prices are still low, Chinese rice remains far cheaper than Korean rice with the price gap is still on the rise. In anticipation of such fierce competition, Korea must carefully review its current policies and closely follow the evolution of rice production, marketing, and trade in China. This study also suggests some of the possible research using more recent data that should be conducted in the future.

과거에 비해 현재의 디스크 저장 공간은 비약적으로 증가하고 있으며, 네트워크상에서도 이전과 비교할 수 없는 수많은 데이터들이 처리되고 있다. 이러한 데이터의 대용량화는 앞으로도 계속 될 추세이지만, 그에 비해 포렌식 관점에서 데이터를 이미징 하는 시간을 개선시키기 위한 연구는 부족한 상황이다. 본 논문은 데이터 이미징 시간을 개선시키기 위한 방안으로 전체 이미징 소요시간 중 해시함수에 대한 소요시간을 암호학적 관점에서 살펴보고, 이를 토대로 EWF 파일 이미징 과정에 대한 효율성 개선 방안을 제안한다.

As an effective means of price discrimination, some suppliers offer trade credit to the distributors in order to stimulate the demand for the product they produce. The availability of the delay in payments from the supplier enables discount of the distributor's selling price from a wider range of the price option in anticipation of increased customer's demand. Since the distributor's lot-size is affected by the demand for the customer, the distributor's lot-size and the selling price determination problem is interdependent and must be solved at the same time. Also, in many common business transactions, the distributor pays the shipping cost for the order and hence, the distributor's ordering cost consists of a fixed ordering cost and the shipping cost that depend on the order quantity. In this regard, we deal with the joint lot-size and price determination problem when the supplier allows delay in payments for an order of a product. The positive effects of credit transactions can be integrated into the EOQ (economic order quantity) model through the consideration of retailing situations, where the customer's demand is a function of the distributor's selling price. It is also assumed that the distributor's order cost consists of a fixed ordering cost and the variable shipping cost. We formulate the distributor's mathematical model from which the solution algorithm is derived based on properties of an optimal solution. A numerical example is presented to illustrate the algorithm developed.

The EIA system was developed during ten odd years of introduction. On the other hand, the contentional development representing systematical fidelity does not match to it. I surveyed the problems of EIA on the point of environmental items with no legal standards. EIA is being executed only once on the planning stage. If the present EIA system has two times of execution, the quality of EIA will be much better. First, on the stage of deciding location of the project, EIA should be done. And next, detailed EIA should be done on the stage of executing the project. To describe the problems of EIA, I surveyed the legislations on the point of the former stages, investigation of present status and anticipation. And I tried a theoretical approach to EIA. The knowledge of things, the subject's standpoint and his valuation are all put together in the EIA. The knowledge of relationship between air and water pollutants and their impact on human is accumulated much. On the other hand, the knowledge of the compounded item, fauna-flora(natural ecology) is partial and causes many difficulties. I pointed out the absurdities of assessment technique dealing the standards and introduced assessment technique being applied to items with no physico-chemical standards such as wild lives.

This research shows the improved methodology which can be applied for universities which want to set up their GHG inventories. In other words, we tried to make guideline in problems due to the unique characteristics of universities. This guideline will help university to deal with the problems they are facing: For example university has less enforcement in operational control compared to the business sector. And it also has various usage of facilities, although these facilities are not maintained by same principal agent. The difference between owner and manager is an another reason for difficulty in setting group organization. The improved and adaptable methods responding to these problems were suggested from this research. The results of this research says the new definition of function for various actors in university for quality control and quality assurance. Because the suggestions made in this research which concerns with criteria for building of universities' GHG inventories were all read by current legislation, there is an anticipation that this can be an official guideline that can be applied to the universities right away.

The objective of the present study is to review of the system, type of care and utility of the Geriatric Health Care Facility(GHCF) in Japan. Geriatric Health Care Facilities in Japan were started with subsidies from the Ministry of Health and Welfare in 1987 to encourage return of the elderly from hospitals to their homes rather than other destinations such as nursing homes or hospitals. Concerning to the type of care, there is the difference between GHCF and other geriatric care facilities(i.e., geriatric hospital and nursing home). GHCF provides both medical and nursing care. The following services are available for the GHCF's user's. As institutional care services, rehabilitation training, ADL exercise, nursing care and management of medicine, are available. For the out-patients, supplying meals, taking a bath, and rehabilitation services, are also available. The medical treatment fee at the facilities is about US $ 1,500 per month. Expenses for meals, daily necessities, shall be borne by the recipient, Those expenses are about US $ 360 per month. In anticipation of the coming of the aging society, the Goverment must be formulated consecutively several vital policies of measures, especially GHCF, for the elderly in the future few years.

GPGPU의 높은 연산 처리 능력을 활용하여 길고 복잡한 계산을 하려는 시도가 많이 있다. GPGPU 프로그램의 특성상 host와 device 사이에 메모리 복사가 필요하다. 해당 메모리 복사 latency가 길 경우 프로그램의 성능에 많은 영향을 준다. 그래서 GPGPU를 활용한 프로그래밍은 최적화에 따른 성능 차이가 크다. 여러 개의 GPGPU 프로그램을 동시에 실행시키면 메모리 복사와 GPGPU 컴퓨팅이 중첩이 되어 메모리 복사 latency hiding 효과를 기대할 수 있다. 이 논문에서는 메모리 복사 latency hiding을 분석한다. 또 메모리 복사의 성능을 높이기 위해 pinned memory를 사용했을 경우의 제약 조건에 따른 성능 예측 모델링 및 알고리즘을 제안하고 이를 바탕으로 실행할 워크로드를 선택하면 41%의 성능 향상을 보인다.
