This study aims to explain the emergence of Gangnam Region of Seoul as a new cluster of the Korean film industry in the context of its history of growth, recent development characteristics, and its production system. Statistical analyses of Korean industries and in-depth interview surveys to film producers were conducted. The results of the analyses show that there has been obvious tendency of film makers' move from Chungmuro, a traditional cluster of the Korean film industry, to Gangnam and many births of new film makers in Gangnam. This new cluster, however, is operating on informal networking between film makers and related personnel, not on formalized production system composed of specialized functions and labor market. Therefore, it can be called as loosely-articulated cluster. This form of cluster has much to do with production milieu of Gangnam, such as advantages of obtaining information and consumer trend, diverse atmosphere which makes it easier to meet diverse people, favorable environment to embed creativity and fresh idea, etc. This trend of the film industry to orient a specific area can be explained in conjunction with the uniqueness of the film industry, such as uncertainty, project-based work, generation gap between film makers, participation of large companies or increasing size of investment.

This study is about an apparel industry in Guro-Gasan where is growing up to the one of the apparel industry cluster beyond an agglomeration in Seoul. The purpose of this study is twofold: (1) to define industrial functions and roles of Guro-Gasan in a value chain of the apparel industry; and (2) to understand whether an industrial cluster is built on the local networks. This study reviewed formation and transitions of its local industries and industrial size, characteristics, spatial distribution and spatial properties using GIS analysis and field surveys. Through in-depth interviews, it analyzed the production system and spatial dispersion of the value chain to understand its functions and roles.

In this paper, we propose a method to generate defocusing images at the focusing plane using the 3D spatial information of object through pickup process of integral imaging technique. In the proposed method, the focusing and defocusing images are generated by the convolution operation between elemental images and ${\delta}$ function array. We observed the image difference by defocusing degree according to the distance of focusing plane. To show the feasibility of the proposed method, some preliminary experiments are carried out and the results are presented.

This study investigated the agglomeration process of the towel industry in the Daejeon and Chungcheong regions, which are located in the mid-western part of South Korea, focusing in particular on industrial restructuring. Moreover, it aimed to identify the spatial features of the towel industry by analyzing the subcontracting linkages and to discover the implications of such linkages on government policy. The towel industry in the Daejeon and Chungcheong regions began to grow from the end of the Korean War when textile technicians from North Korea settled down in this area, spreading their techniques and know-how within the region. Later, in the 1980s, the industry underwent restructuring when companies within the region strengthened their linkages through corporate specialization based on the concept of social division of labor. Accordingly, the industrial linkages and linkage spaces, as well as characteristics of the industry, should all be considered to develop and implement policies for the regions of the towel industry.

It is necessary to develop a new location model to support the application of smart technology and confluence in the 4th industrial revolution era. In this study, we propose 'network-type industrial complex' as a method to link several industrial integrated spaces which are dispersed in an area. As a result of conducting a survey of companies in order to develop a new location model, about 89% of companies recognized the necessity of network-type industrial complex. As a condition for activation of the industrial complex, 'complementary function formation', and 'convenience of nodular transportation' were selected. It is expected that it will be possible to supply low-cost, high-efficiency industrial complexes through opening and linking with urban space and infrastructure sharing.

In this paper, the resonance characteristics of zigzag wire dipole antennas are first analyzed by the method of moment(MOM) for shortening the space occupation length of straight wire dipole antenna Considering the shortening effect the integrated zigzag dipole antennas with the simplified microstrip feed are designed. Since the integration gives rise to discontinuities due to antenna line width with abrupt bend angles, the compensation by the chamfer is applied. Futhermore the integrated parasitic zigzag lines are properly attached to both sides of substrate for compensation of the effect of the dielectric substrate, hence improving the resonance characteristic. The design results at UHF and ISM band are verified with experiments.

본 연구는 국내 소프트웨어 산업의 새로운 집적지로 떠오르는 강남·서초지역이 과연 산업지구적 성격을 지니고 있는지를 이론적·경험적 측면에서 살펴보기 위한 것이다. 이를 위하여 기존연구로부터 산업지구의 성격과 발달에 관한 다섯 가지 차원-국지화, 네트워킹, 착근성·제도적 집약, 잡단학습, 혁신 시너지-을 도출하였다. 실증연구에서는 소프트웨어 업체의 입지변화와 창업의 공간적 분포를 살려보았으며, 설문조사 자료를 토대로 강남·서초지역이 타 지역에 비해 어떤 산업지구 차우너이 발달하였는지 분석하였다. 분석 결과 강남·서초 지역은 산업지구의 최소 요건인 물리적 집적에서는 상당한 발전을 보였으며, 혁신의 결과인 창업에 있어서도 여타 지역과는 차별화된 성과를 나타냈다. 설문분석 결과 강남·서초지역은 서울시내 타 지역에 비해 '국지화', '착근성과 제도적 집약', 그리고 '집단학습' 등의 측면에서는 뚜렷한 차이를 보였다. 이에 비해, '혁신 시너지'는 타 지역과 유사하였으며, '네트어킹'은 오히려 미흡한 결과를 보였다.

최근 테라헤르츠 대역의 주파수를 이용하여 데이터 전송속도 10Gbps 이상의 초고속 통신 시스템에 대한 관심이 높아지고 있다. 테라헤르츠 대역의 주파수 범위는 100GHz~10THz로서 종래의 밀리미터파 대역에서 사용하고 있는 대역폭에 비하여 월등히 넓은 주파수 대역폭을 제공하여 주기 때문에 미래의 초고속 통신시스템 응용에 무한한 잠재적 가치를 가지고 있다. 테라헤르츠 전파는 전자파와 광파의 특성을 모두 가지고 있어 공간으로 전파하며 광의 특성에 따라 광학 렌즈를 이용하여 방사 빔을 집속할 수 있다. 또한 테라헤르츠파는 전파 감쇠가 대단히 커서 현재의 기술수준을 고려해 볼 때 10m 정도의 단거리 통신에 적합하다. 미국, 유럽, 일본 등 테라헤르츠 선도국에서는 핵심 부품 및 MMIC 등의 연구 개발에 많은 투자를 하고 있다. 본 고에서는 테라헤르츠 통신을 위한 집적화 RF 송수신기 기술개발 동향에 대하여 소개하고자 한다.

본 논문에서는 포맷 변환기를 사용하여 여러 가지 영상처리 필터링을 구현하였다. 이러한 설계기법은 집적회로를 이용한 대규모 화소처리배열을 근거로 하여 실현하였다. 집적구조의 두가지 형태는 연산병렬프로세서와 병렬 프로세스 DRAM(또는 SRAM) 셀로 분류할 수 있다. 이러한 포맷 변환기 설계는 효율적인 제어 경로 수행을 능력을 가지고 있으며 하드웨어를 복잡하게 한 필요 없이 고급 기술로 사용 될 수 있다. 실험 결과 1)단순한 평활화는 더 높은 공간의 주파수를 억제하면서 잡음을 감소시킬 뿐 아니라 에지를 흐리게 할 수 있으며, 2) 평활화와 분할 과정은 날카로운 에지를 보존하면서 잡음을 감소시키고, 3) 평활화와 분할과 같은 메디안 필터링기법은 영상 잡음을 줄이기 위해 적용될 수 있고 날카로운 에지는 유지하면서 스파이크 성분을 제거하고 화소 값에서 단조로운 변화를 유지 할 수 있었다.

This research investigates that role of space-based social capital presented in Dapsimni auto-parts shopping area considering Korean auto-parts industry and the regional characteristics of retailing industrial cluster. For this, it went through the process with in-depth interview and surveys of the owner of Dapsimni, social capital of retailing industrial cluster studied using Lin(1999)'s social capital model by separating formation, accessibility and mobilization of it. The result is that auto-part sellers in Dapsimni make themselves space-based social capital, which provides the profit from certain area: strengthening auto-parts of transaction cost and information exchange among them, creating new market for selling auto-parts. This meant that main factor sustaining the characteristic of retailing industrial cluster despite gradually decline of its role.
