Urban cmmunity films have achieved the industrial modern society's idiosyncrasy Popular films have achieved the industrial growth through city as the completion of modernization. They also have represented the social meaning of urban space, and have expanded 'their political space' This filmic challenge showed diverse negative factors which were the poor's economical difficulties, the relative robbery of their education and job, and adhered class in city through developing the urban space with were hidden beyond modernity's splendor.

얼굴 표정을 애니메이션하는 것은 얼굴 구조의 복잡성과 얼굴 표면의 섬세한 움직임으로 인해 컴퓨터 애니메이션 분야에서 가장 어려운 분야로 인식되고 있다. 최근 3D 애니메이션, 영화 특수효과 그리고 게임 제작시 모션 캡처 시스템(Motion Capture System)을 통하여 실제 인간의 동작 및 얼굴 표정을 수치적으로 측정해내어 이를 실제 애니메이션에 직접 사용함으로써 막대한 작업시간 및 인력 그리고 자본을 획기적으로 줄이고 있다. 그러나 기존의 모션 캡처 시스템은 고속 카메라를 이용함으로써 가격이 고가이고 움직임 추적에서도 여러 가지 문제점을 가지고 있다. 본 논문에서는 일반 저가의 카메라와 신경회로망 및 영상처리기법을 이용하여 얼굴 애니메이션용 모션 캡처 시스템에 적응할 수 있는 경제적이고 효율적인 얼굴 움직임 추적기법을 제안한다.

The present study attempted to identify the relationship among cognition of service quality, cognition of contribution, and satisfaction in the international film festival context. A sample survey of 1,897 visitors of eight major international festivals held in Korea was administered throughout the year 2008. The factor analysis identified four factors of service quality. The structural modeling confirmed that all the four service quality factors and cognition of contribution positively affected the satisfaction. The study revealed the constructs of service quality, contribution, and satisfaction in the international film festival context.

복잡계 과학의 발달에 따라 많은 사회 네트워크들이 분석되고 있다. 우리는 연결선수, 중간성(betweenness), 결집계수와 같은 링크수를 중심으로 네트워크의 구조적 분석에서 나아가 복잡한 네트워크 속에서 핵심 되는 중심 모듈을 찾아 분석하였다. K-core알고리즘은 복잡계 네트워크를 가중치가 낮은 링크와 노드를 단계적으로 제거하여 복잡한 네트워크의 의미를 분석함에 있어 핵심이 되는 모듈을 얻는데 용이하다. 이에 소설, 영화, 과학 교과서, 단백질 상호작용 네트워크와 같은 다양한 분야에 이 알고리즘을 직접 적용해보았다. 그 결과, 각기 복잡한 네트워크로부터 핵심이 되는 모듈을 찾아낼 수 있었고, 전체 네트워크에서는 발견하기 힘든 유용한 정보들을 도출할 수 있음을 확인하였다. 본 연구에서 k-core 알고리즘을 통해 핵심 네트워크를 구축하여 유용한 정보를 도출할 수 있는 가능성을 제시하였다.

The capacity spectrum method (CSM) can be used for the evaluation of inelastic maximum response of structures and has been recently used in the seismic design using the incorporation of pushover analysis and response spectrum method. To efficiently evaluate seismic performance of multi-degree-of freedom (MDOF) bridge structures, it is important that the equivalent response of MDOF bridge structures be calculated. In this study to calculate the equivalent response of MDOF system, equivalent responses are obtained by the using Song method, N2 method and Calvi method. Also, these are applied the CSM method and seismic performance of bridge according to the ESDOF method are compared and evaluated.

We present a precedure for interpreting dipole-dipole apparent resistivity data. The procedure is constructed by combining a forward two-dimensional finite element modeling and an inverse technique with Householder's transformation. In the interpretation, subsurface structure is divided into some blocks with constant resistivities. Our inversion technique is tested on synthetic and field data. We found that geologic constraint is required for successful interpretation.

The epidermis of scales in the abdominal parts from freshwater- and seawater-adapted guppies(Poecilia reticulatus) were studied respectively by scanning- and transmission- electronmicroscope. In the seawater adapted group, the surface area of pavement cells is increased nearly twice as much as that of freshwater-adapted group, and the pavement cells are relatively flattened. Adaptatoin to seawater causes the increment of the density of glycocalyx in the surface of the microridge of pavement cells, as well as the well developed intercellular junctional complex(desmosome) between neighbouring filament-containing cells. Also, intercellular space between adjacent filament-containing cells is more frequently observed in the epidermis of seawater adapted guppy.

In this paper, the importance of the size effects on the strength ratio is demonstrated by numerical results. The rate of decrease of tensile strength is for glass fiber, based on the experience of a composite manufacturing specialist. For other material, similar procedure may be used until detailed test result on such material is available. The strength criteria used is that of Tsai-Wu for stress space. The factors influencing the ratio are, reducing the tensile strength alone or both tensile and compression strengths, selection of the normalized interaction term, that is, the generalized Von Mises criterion or the Hill's criterion, and the status of applied stresses. Some of the numerical results are presented for a guideline for the furture study.

This study is concerned about the development of tower type automatic tool changer. The tower type automatic tool changer is developed to reduce stand-by time by shortening tool change time. The developed system can store more number of tools in small space. A structural analysis for the machine is carried out to check the machine design using commercial software, CATIA V5. In the result of structural analysis, the safety of the developed system is confirmed.

The Government is managing "The Comprehensive Development Plan of Fishing Villages" which is a national program to ensure the effective use of the coast and reasonable management of fisheries resources. The Chuja-do was selected as an area for "The Comprehensive Development of Fishing Villages" because it has the characteristics of local independence and an advanced fishery using boats. The study covered the environment of the local fishing grounds, all aspects of the coast fishing and residents' thinking. The results of the study led to the following proposals : development of the coastal fishing grounds farmining industry, establishing the fishing grounds industry by dropping arcificial fish reefs, developing the tourist industry, improving the quality of fishery using boats, and establishing high quality fishing specialties.
