Dongdaemun fashion market has been successfully positioned as a main hub for non-brand fashion product distribution in Korea. One of important competitive advantages of Dongdaemun market often quoted by retail researchers is an efficiently managed network system among supply chain members. This study aimed to examine the importance of buyer-supplier relationship elements and supplier properties from buyers' perspectives (small & very small-sized fashion stores in Dongdaemun market), and to identify the determinants of the relationship length between suppliers and buyers. Survey responses of 233 stores were analyzed using EQS 6.1 for Window and SPSSWIN 10.0. The findings could be summarized as follows: First, fashion stores perceived that right delivery as the most important factor, and geographically closeness, design capability, quality, and lower price followed in order. Second, the characteristics of stores such as location, wholesaling versus retailing focusing, monthly sales, and total business length all affected the perceived importance of buyer-supplier relationship. Third, design capacity, communication, power was identified as determinants of actual relationship length with a supplier, while communication and trust were found to be determinants of future expected relationship length.

This study investigated the factors influencing the knowledge acquisition of Thai local partners from advanced foreign partners through international joint ventures(IJVs). For this purpose, this study initially identified three dimensions of characteristics in the context of IJVs that would influence local partners' knowledge acquisition - a local partners' own characteristic (absorptive capacity), a relationship characteristic with IJVs (proximity to the equal equity ownership), and a relationship characteristic with foreign partners (trust), and examined their effects on local partners' knowledge acquisition. The study further investigated the moderating effects of the tacitness of knowledge on the relationships between those characteristics and knowledge acquisition. Based on the data collected from Thai IJV local partners, results revealed that a local partners' own characteristic, absorptive capacity, and a relationship characteristic with IJVs, proximity to the equal equity ownership, had a strong positive effect on local partners' knowledge acquisition. Results further showed that the tacitness of knowledge strengthened the relationships between absorptive capacity and knowledge acquisition and between trust and knowledge acquisition, but not the relationship between proximity to the equal equity ownership and knowledge acquisition.

The meanings and roles of community have been changed. Traditional community theories hinged on the neighborhood have been threatened by the alternative concept of 'communities without propinquity'. Embracing unprecedented development of transportation, information and communication technologies, Propinquity of community has not been a precondition. This paper reviews the development of community theories with a frame of 'communities without propinquity'. Furthermore, applying social network analysis(SNA) approaches, it explores the communality of Topgol Comic Book Space, located in Goesan, Chungbuk and examines spatial characters. Visitors' networks of Topgol Comic Book Space builda up national coverage and expands. It functions as a field of testing various activities without explicit 'fixed purpose'. The case exemplifies a community, continuously enlarging the spatial and social boundaries, performing a series of activities, and connecting both the outside and the local.

When planning to construct adjacent structure by the side tunnel, the criteria of safety zone of tunnel have been proposed. There are no specific theoretical basis regarding load conditions and the distance of structure and the geological strata and the conditions of adjacent structure's location, and the conditions applied load. Two and three dimensional numerical analysis preformed to prove the deformation of the ground and structures caused by the tunnel excavation and evaluated the correlation and the suitability of the tunnel's safety zone regarding the location of adjacent structures and the changes in the modulus of deformation. This paper proposed the safety zone's range is getting bigger as the modulus of deformation is higher. Also, it seems that the possible range of construction under constraints in the diagram of revalued safety zone significantly expands as shear failure line appears on the invert extension line below the spring line.

A optimal reinforcement in the joint rock slope excavation adjacent to an existing tunnel would be influenced by excavation distance from the tunnel, slope angel, and joint conditions but has been empirically determined so far. In this study, large scale model tests were conducted to find out the relationship between load translation on the excavation surface and bebavior of the tunnel according to excavation steps of the jointed rock slope. Consequently, two main parameters, joint dip and sloped angle were investigated in those model tests. From the test results, it was found that tunnel deformation was the largest one when the excavation of joints located closer to the tunnel crown or invert. Stability of the slope and the tunnel were varied in a certain excavation stage related to the angle of slope. In the future, based on results of this study the reinforcement method for the tunnel and slope safety in a jointed rock mass will be demonstrated.

본 연구에서는 행성 근접통과(Gravity Assist, Swingby, Flyby)를 이용한 행성간 탐사선의 궤도를 설계할 수 있는 알고리즘 개발을 자체적으로 수행하였다. 미 항공우주국(NASA)에서는 이를 이용한 행성간 탐사선의 궤도에 관한 연구를 이미 1950년대부터 시작하여 왔으며, 1973년 Mariner 10호가 한번에 두 행성, 금성과 수성을 탐사하는데 성공하였다. 행성간 임무에 있어서 행성 근접통과를 적절하게 이용한다면 임무 수행시 요구되는 에너지를 최소화 시킬 수 있어 발사비용의 절감효과와 함께 한번의 발사로 여러 행성의 탐사가 가능하여 임무의 효율성을 증대 시킬 수 있다. 행성 근접통과를 이용한 행성 탐사선의 궤도설계를 위해서는 근접 통과하는 행성(Flyby planet)에서의 진입속도벡터( $V_{\infty}$$^{ -}$) 및 출발속도벡터( $V_{\infty}$$^{+}$)의 크기, 근접 통과시의 비행 고도(Flyby altitude), 근접 통과 행성과의 충돌여부 분석(B-plane analysis), 최종적으로 도착하고자 하는 행성(Target planet)의 위치 등 많은 제한조건이 고려되어야 한다. 연구된 알고리즘의 결과를 미 항공우주국 (NASA)의 임무였던 Mariner 10호의 결과와 비교하여 보았으며, 우리나라가 향후 목성으로 탐사선을 보낸다고 가정하였을 경우, 행성 근접통과를 이용한 탐사선의 발사시기(Launch Window), 요구되는 발사 에너지(C3)값, 그리고 각각에 따른 궤적들을 산출하여 보았다. 이미 기술 개발을 완료한 국가들이 관련 기술의 제휴를 기피하고 있는 현 상황에서 이와 관련된 연구는 우주개발의 시대를 열고 있는 우리나라의 우주개발관련 기초 기술 분야를 위해 선행 연구되어야 할 부분이다. 기초 기술 분야를 위해 선행 연구되어야 할 부분이다.다.향을 해석하고 시뮬레이션 하였다.Device Controller)는 ECU로부터 명령어를 받아서 arm 및 safe 상태에 대한 텔리 메트리 데이터를 제공한다 그리고, SAR(Solar Array Regulator)는 ECU로부터 Bypass Relay 및 ARM Relay에 관한 명령어를 받아 수행되며 그에 따른 텔리 메트리 데이터를 제공한다. 마지막으로 EPS 소프트웨어를 검증하는 EPS Software Verification을 수행하였다 전력계 소프트웨어의 설계의 검증 부분은 현재 설계 제작된 전력계 .소프트웨어의 동작 특성 이 위성 의 전체 운용개념과 연계하여 전력계 소프트웨어가 전력계 및 위성체의 요구조건을 만족시키는지를 확인하는데 있다. 전력계 운용 소프트웨어는 배터리의 충ㆍ방전을 효율적으로 관리해 3년의 임무 기간동안 위성체에 전력을 공급할 수 있도록 설계되어 있다this hot-core has a mass of 10sR1 which i:s about an order of magnitude larger those obtained by previous studies.previous studies.업순서들의 상관관계를 고려하여 보다 개선된 해를 구하기 위한 연구가 요구된다. 또한, 준비작업비용을 발생시키는 작업장의 작업순서결정에 대해서도 연구를 행하여, 보완작업비용과 준비비용을 고려한 GMMAL 작업순서문제를 해결하기 위한 연구가 수행되어야 할 것이다.로 이루어 져야 할 것이다.태를 보다 효율적으로 증진시킬 수 있는 대안이 마련되어져야 한다고 사료된다.$\ulcorner$순응$\lrcorner$의 범위를 벗어나지 않는다. 그렇기 때문에도 $\ulcorner$순응$\lrcorner$과 $\ulcorner$표현$\lrcorner$의 성격과 형태를 외형상으로 더욱이 공간상에서는 뚜렷하

비디오 데이터베이스에서 움직임 정보를 가지고 있는 이동객체에 대한 모델링은 크게 두 가지 측면 즉, 공간적 혹은 시간적 관계성에 의해 다루어진다. 공간적 관계에서 위상 관계는 근접 그래프에 의한 모델링이 대부분이며, 이를 이용한 내용 기반 비디오 검색에서 자연어 형태의 질의어는 정형화된 위상 관계 표현으로 변환하는 과정을 거친다. 그러나 이 과정에서 위상 관계 표현이 인간이 사용하는 언어의 의미를 정확히 반영하는지는 알 수 없다. 이에 본 논문에서는 위상 관계 표현과 인간이 사용하는 움직임 동사간 의미의 차이를 줄이기 위해 위상 관계 표현과 실제 움직임 동사간의 매칭에 대해 연구했다.

We explore the impact of individuals'network position toward knowledge sharing intention. In order to identify network positions, we utilize three centrality measures (degree/closeness/betweenness) of individual network participants. The research findings show that the individual network positions significantly affect knowledge sharing intentions. Since an individual with high degree centrality might be the leader or the hub, one makes considerable effort to maintain the network position by actively participating in intra-team and inter-team knowledge sharing, A participant who can quickly interact with many other participants within a team (high closeness centrality) is more interested in intra-team knowledge sharing than inter-team knowledge sharing. Unlike degree centrality and closeness centrality, the betweenness centrality provides a participant with diverse resources located in multiple sub-groups. Although an individual with high betweenness centrality is not at the center of the networks, one plays a crucial role in disseminating and regulating information. Therefore, the individual is likely to have more positive intention toward inter-team knowledge sharing than intra-team knowledge sharing.

This paper aims to critically review the geographical literature on learning and proximity that stresses the role of the regions and geographical proximity in sustaining competitive advantage, and to conceptualize a relational/organizational perspective on the sources of knowledge and learning in the firm. In the first part of the paper, I argue that the geographical literature lacks the deliberate scrutiny of how learning occurs in the firm and where the sources of knowledge and learning come from. Secondly, I attempt to elaborate the concept of proximity through a relational/organizational perspective. Thirdly, I delve into how learning takes place and is realized in the firm through communities in the firm such as communities of practice, epistemic communities and task-force teams and how such communities in the firm generate knowledge and sustain loaming by drawing on relational/organizational proximity. This paper concludes by claiming that the sources of learning exist in organizational spaces, with complex geographies mobilizing distributed knowledge and competences and combining varied forms of knowledge beyond the simple demarcation of tacit and codified knowledge.

작업안전 대책으로서는 기본적으로 인간존중을 바탕으로 안전관리를 추진해 나아가는 것이 가장 좋은 대책이지만 하루에 여러개소의 현장을 이동하고, 각 작업 현장의 형태가 달라질 수 있는 특별한 분야에 있어서는 매우 어려운 요소를 포함하고 있다. 따라서 조금이라도 이에 근접되도록 관계자는 연구와 노력을 계속하여야 하며, 배전작업용 로봇등을 적용하는 특수한 분야에서는 종합적이고 과학적인 방법을 도입하여 작업현장 안전대책을 수립하고 문제점을 적출하여 안전재해 예방에 최선을 다해야 할 것이다.
