This paper examines the relationship between the locational patterns of global and domestic stores. Objective corporation for this research is the Daiei Inc., which is multinational retail corporation of general merchandise store industry. Used data are For the Customers and 1997 Annual Report published by the Daiei Inc. in 1997, and Worldwide Branch Location of Multinational Companies published by the Gale Researchy Inc. As a result it is recognized that the headquarters of supermarket companies are not necessarily established in the largest city of the store networks. In addition, the chani o stores does not always correspond to the economic territory area of a city or a regional urban system. Usually, supermarkets are established first one after another around the headquarter, so that the store network becomes intensive. Moreover, supermarket companies exhibit a tendence of expanding after having increased density of their stores in their indigenous regions. It seems that supermarket companies try to lay the foundation of their operation firmly on their indigenous regions, while they expand the store network into neighboring regions in order to enlarge their profits. This phenomenon appears more and less partly in the location of oversea purchasing offices. First oversea office location appears in neighboring countries whose headquarter is located in Japan. Another oversea office location is established in higher order city of another continent. Usally after the number of oversea offices increases in their headquarter's neighboring region, the oversea office network exhibits a tendency of expanding in another continents. in addition, network of oversea offices does not always correspond with world urban system. The location of oversea offices is formed, after internalization of supermarket stores was established in Japan. And when increasing rates of supermarket stores was low in Japan, number of oversea offices increased.

고성능 슈퍼스칼라 프로세서에서 값 예측 실패 시에 잘못 예측된 값을 사용하여 모험적으로 수행된 명령들만을 순차적으로 취소하고 복구한 후에 재이슈하는 값 예측 실패 복구 메커니즘을 제안한다. 제안된 복구 방식은 값 예측이 틀린 종속명령만을 선택적으로 재이슈하여 불필요한 재이슈를 줄임으로써 값 예측 실패 시에 손실을 줄인다. 또한 기존의 방식들처럼 잘못 예측된 명령에 종속적인 명령들의 한번에 병렬로 검색하지 않고 명령들의 종속체인을 따라 순차적으로 검색함으로써 프로세서의 클럭 사이클에 영향을 미치지 않으면서 하드웨어의 구현의 복잡성을 줄인다.

The Korean distribution industry is gearing up for an endless competition. Greeting low growth era, less competitive parties will be challanged seriously for their survival. But for large discount stores, they have shown steady annual growth for years. However, because of the saturation for numbers of stores, the difficulty of gaining new sites, and the changes in the consumer's consumption behavior caused by the recession, now they are seeking for a new customers-based business formats. Accordingly, a large corporate comopanies made supermarkets which are belonged to affiliated companies of large corporate comopanies. They based on the strong buying power, focused on SSM(Super Super Market) ave been aggressively develop nationwide multi-stores. The point is that these stores are threatening at small and medium-sized, community-based private supermarkets. Private supermarkets and retailers, who are using existing old operation systems and their dilapidated facilities, are losing a competitive edge in business. Recent the social effects of large series of corporate supermarkets for traditional markets has been very controversial, and commercial media, academia, and industry associated with it have been held many seminars and public hearings. This may slow down the speed in accordance with the regulations, but will not be the crucial alternative. The reason for this recent surge of enterprise-class SSM up, one of the reasons is a stagnation in their offline discount mart, so they are finding new growth areas. Already in the form of large supermarkets across the country got most of the geographical centre point and is saturated with stages. Targeting small businesses that do not cover discount Mart, in order to expand business in the form of SSM is urgent. By contrast, private supermarkets are going to lose their competitiveness. The vulnerability of individual supermarkets, one of the vulnerabilities is price which economies of scale can not be realized so they are purchasing a small amount of products and difficult to get a quantity discount. The lack of organization and collaboration, and education which is not practical, caused the absencer of service-oriented situations. As a first solution, making specialty shops which are handling agricultures, fruits and vegetables and manufactured goods is recommended. Second, private supermarkets franchisees join the organization for the organization and collaboration is recomaned. It can be meet the scale of economy and can be formed a alternative business formats to a government. Third, the education is needed as a good service will get consumer's awareness. In addition, a psychological stores operating is also one way to stimulate consumer sentiment as SSM can't operate. Japan already has a better conditions of their lives through small chain expression. This study includes the vulnerabilities of private supermarkets, and suggests a competitiveness reinforcement strategies.

In this paper, requirements of efficient group key creation in multiple hierarchy structure environment with clear distinction of hierarchical roles within organizations are explained and the method of creating a group key that satisfies such requirements is proposed. The proposed method creates the group key through logical sum operation of hierarchy identifier created using uni-directional hash chain and group identifier randomly created according to the access right. The problem of excessive possession of key information by upper group users in the existing static group key creation technique was resolved. At the same time, lower group users were prevented from deducing key information of upper group users. In addition, as a result of comparative analysis performed with an experiment on existing super group key creation technique and multiple hierarchy group key method, the proposed method was found to be equivalent or superior to existing method in terms of various items including the total number of keys created, the number of keys possessed by users, the number of keys used for encoding and decoding of information, and expandability of keys.

초고분자량 폴리에틸렌(UHMWPE)섬유는 현재까지 알려져 있는 섬유중 비강도가 가장 우수하며 강도 또한 최고 40g/d를 나타내는 슈퍼섬유중에 하나이다. UHMWPE섬유는 비교적 간단한 분자구조로 이루어져 있으며 높은 결정화도로 인해 광 안정성 및 자외선 저항성이 우수하며 내마모성도 뛰어나다. 이러한 특성으로 인해 최근 로프 및 어망 등의 산업적 용도 뿐만 아니라 익스트림 스포츠웨어를 포함한 의류소재에도 다양하게 적용되고 있다. 하지만 의류소재 적용에 앞서 초소수성으로 이루어진 분자구조와 낮은 내열성으로 인해 염색이 쉽지 않으며 다양한 색상을 구현하기가 힘든 실정이다. 현재 본 연구실에서는 이와 같은 문제점을 해결하기 위해 UHMWPE섬유에 염색이 가능한 염료를 개발하였으며 보다 다양한 색상을 구현하기 위해 연구를 진행 중이다. 현재 본 연구실에서는 UHMWPE섬유 염색에 있어 Blue, Red, Yellow, Magenta 계열의 색상구현이 가능하며 보다 심색화 된 색상을 구현함으로 인해 의류용 섬유소재 및 산업용 섬유소재에 다양하게 적용할 수 있도록 UHMWPE섬유용 염료합성 실험이 진행되고 있다. 안트라퀴논 및 아조계 염료에 초소수성 알킬체인을 치환함으로써 염료의 소수성을 증가시켜 초소수성 섬유인 UHMWPE섬유에 염착성을 증가시키고 높은 견뢰도 결과를 확보하였다. 또한 내열성이 낮은 특성에도 불구하고 염색 이후 UHMWPE섬유가 가지는 물성에는 큰 변화를 나타내지 않았다.

This study empirically examines the impact of SSM market entry on changes in market shares among retailing types. The data is monthly time-series data spanning over the period from January 2000 to December 2010, and the effect of SSM market entry on market shares of retailing types is analyzed by utilizing several key factors such as the number of new SSM monthly entrants, total number of SSMs, the proportion of new SSM entrant that is smaller than $165m^2$ to total new SSM entrants. According to the Korean Standard Industrial Classification codes, the retailing type is classified into 5 groups: department stores, retail sale in other non-specialized large stores(big marts), supermarkets, convenience stores, and retail sale in other non-specialized stores with food or beverages predominating (others). The market shares of retailing types are calculated by the ratio of each retailing type monthly sales to total monthly retailing sales in which total retailing sales is the sum of each retailing type sales. The empirical model controls for the size effects with the number of monthly employees for each retailing type and the macroeconomic effects with M2. The empirical model employed in this study is as follows; $$MS_i=f(NewSSM,\;CumSSM,\;employ_i,\;under165,\;M2)$$ where $MS_i$ is the market share of each retailing type (department stores, big marts), supermarkets, convenience stores, and others), NewSSM is the number of new SSM monthly entrants, CumSSM is total number of SSMs, $employ_i$ is the number of monthly employees for each retailing type, and under165 is the proportion of new SSM entrant that is smaller than $165m^2$ to total new SSM entrants. The correlation among these variables are reported in
