This study considered the transition of changes in social status of the film through the discourse analysis of printed media, having been published since 6th revised film policy in 1987. For the purpose, Pierre Bourdieu's cultural sociology, or 'Field theory approach' was engaged as a theoretical background. On the basis of that theory, changes in social status was divided into expert and popular field. From 1988 to 2007, doctor's and master's theses on filmologie and the representative academic journal, "Film Studies" were examined with regard to area of expertise, and movie-related books with regard to popular one. This study demonstrated that the symbolic capital had inhered in the cinematic field along with specialization and diversification of analytic aspects, and the relation between the academic approach and political consideration had performed an important role in intellectualization of film.

인테리어 디자인학은 보편적으로 건물의 내부공간, 즉 매우 명확한 경계들을 전제로 잘 정의된 공간들에 관한 연구로 그 범위가 제한되어져 왔다. 따라서 건축, 도시, 또는 매우 광대한 의미에서의 환경디자인의 특권으로 알려져 있는 도시에 관한 쟁점을 그다지 자주 다루지 않는 편이라 할 수 있겠다. 그러나 극도로 고밀도화된 현대의 대도시들은 주요 지하 교통망을 중심으로 상업, 유흥, 업무시설 그리고 경우에 따라서는 주거단지에 까지 쉽게 연결되는 거대한양의 전이 실내공간들을 창출해내고 있다. 이것이 최근 홍콩의 건축가 게리 챙(Gary Chang)에 의해서 규정된 새로운 개념의 고밀도 도시 인테리어 랜드스케이프(interior landscape)인 것이다. 이러한 인테리어스케이프의 개념은 현대 도시의 모습 중에서 가장 흥미로운 개념들 중의하나라 할 수 있는데 다양한 요소들이 혼합된 그 특성은 이제 사회학, 건축, 인류학, 도시탐험, 인테리어 디자인, 도시 그리고 환경 디자인 등 다양한 분야에서 뜨거운 논쟁의 주제로 떠오르게 된 것이다. 이제 도시에 관한 연구는 더 이상 외부에서 내부로 진행되는 것이 아니고, 내부에서부터 출발되는 것이다. 극도로 밀집된 아시아의 대도시들은 이렇게 혼잡한 도시환경의 모든 요인들을 더 잘 이해할 수 있도록 다양하고 흥미로운 상황들을 제공해 주고 있다. 상업적 목적으로 건물 전체를 사용하는 수직적 전략이나 다양한 문화적 행태들은 도시 환경의 '혼잡성'을 그냥 참을만한 것이 아니라 오히려 그 도시만의 매력적 요소로 부각시켜 주는 것이다. 본 논문은 인테리어스케이프를 중심으로 진행되고 있는 다양한 이론적 논쟁들의 분석에 그 기초를 두고 있다. '장소성의 부재'의 개념, 혼잡의 문화, 공공공간의 사유화, 결절도시, 한계의 개념들을 분석하여 아시아 대도시들이 어떻게 이러한 쟁점들을 그들 자신만의 고유한 해결책으로 발전시키는지를 고찰하고자 한다. 본 논문의 목적은 서울을 사례분석 중 하나로 사용하여 인테리어 디자인 분야의 경계를 대도시로 확장하는 동시에 새로운 적용영역의 가능성을 탐구하는데 있다 하겠다.

Automation of observation and positioning of fiducial marks is made possible with the application of image matching technique, developed through the cooperative research effort of computer vision and digital photogrammetry. The major problem in such automation effort is to minimize the computing time and to increase the positional accuracy. Except for scanning and ground control surveying, the interior orientation process was automated in this study, through the development of an algorithm which applies the image matching and image processing techniques. The developed system was applied to close-range photogrammetry and the analysis of the results showed 54% improvement in processing time. For fiducial mark observation during interior orientation, the Laplacian of Gaussian transformation and the Hough transformation were applied to determine the accurate position of the center point, and the correlation matching and the least squares matching method were then applied to improve the accuracy of automated observation of fiducial marks. Image pyramid concept was applied to reduce the computing time of automated positioning of fiducial mark.

Data-centric storage schemes(DCS) are one of representative researches that efficiently store and manage sensor readings in sensor nodes in the sensor networks. In DCS, a sensor sends the sensed data to a specific node in order to store them. However, it has a problem that sensor nodes consume a lot of energy for transmitting their readings to remote sensor node. In this paper, we propose a novel sensor data compression algorithm to reduce communication costs for DCS. The proposed algorithm establishes a safe region and transmits the sensed data only when current measurement is out of the safe region, As a result, the proposed algorithm extends network life time and reduces data transmission. It is shown through performance evaluation that our proposed algorithm reduces energy consumption by about 60% over the conventional algorithm.

Numerical simulations were done using depth integrated ADCIRC model in order to evaluate dynamic response on the inner Saemankeum reservoir due to flood flow and gate operation for the both situations of dike construction and inner development. According to 2-dimensional dynamic flood routing, temporal variation of hydrographs shows sensitive at upstream riverine region while it becomes stable from the center part of the reservoir due to sudden expansion of physical changes. Dynamic response of hydraulic changes such as water surface elevation and velocity on the inner region arises suddenly by gate operation and more rapidly after the inner development than dike construction. Temporal surface fluctuation arises during inflowging of outer sea water and propagates upstream up to 10km to 16km in accordance with inner development status.

For overall system test, hidden-target test have been used using film which leads to inherent analysis error. The purpose of our study is to quantify this error and to propose gel dosimeter based verification technique for 3-dimensional target point error. The phantom was made for simulation of human head and this has ability to equip 10 gel-dosimeter. $BANGkit^{TM}$ which we are able to manufacture whenever it is needed as well as to easily change the container with different shapes was used as a gel dosimeter. The 10 targets were divided into two groups based on shapes of areas with a planned 50% isodose line. All treatment and analysis was performed three times using Novalis and $BrainSCAN^{TM}$. The target point error is $0.77{\pm}0.15mm$ for 10 targets and directional target point error in each direction is $0.54{\pm}0.23mm$, $0.37{\pm}0.08mm$, $0.33{\pm}0.10mm$ in AP (anterior-posterior), LAT (lateral), and VERT (vertical) direction, respectively. The result of less than 1 mm shows that the treatment was performed through each precise step in treatment procedure. In conclusion, the 3-dimensional target point verification technique can be one of the techniques for overall system test.

The damage caused by information spill, forgery, falsification, and deletion by cyber infringement in educational institutions and universities is very large. In this study, we analyzed the types, causes, and problems of cyber infringement in educational administrative institutions and universities. As a result, administrative, physical and technical information protection activities were weak. In this paper, we propose a security enhancement method for each domain by dividing them into Internet zone, network-neutral zone (DMZ: Demilitarized Zone), general server zone, internal server zone (Server Farm), and user zone so that these vulnerabilities can be easily identified, supplemented or security enhanced. In addition, we have proposed a method to apply security information system architecture and information protection technology correctly for educational administration institutions and universities. This study is meaningful not to provide conceptual guidance but to suggest specific action and procedure oriented security management plan.

This paper proposes a robust and efficient segmentation method for a cardiac ultrasound image taken from a probe inserted into the heart in surgery. The method consists of three steps: initial boundary extraction, whole boundary modification using confidence competition, and local boundary modification using the rolling spoke method. Firstly, the initial boundary is extracted with threshold regions along the global spokes emitted from the center of an ultrasound probe. Secondly, high confidence boundary edges are detected along the global spokes by competing among initial boundary candidate and new candidates achieved by edge and appearance information. finally, the boundary is modified by rolling local spokes along concave regions that are difficult to extract using the global spokes. The proposed method produces promising segmentation results for the ultrasound cardiac images acquired during surgery.

It is very difficult to predict what effects the introduction of IFRS(International and Financial Reporting Standars) has on the existing system. Only the cautious and careful adoption of new system will minimize the confusion. The purpose of this paper is to propose appropriate design and construction of IS on financial statement according to the introduction of IFRS(International Financial Reporting Standard) in order to minimize the confusion. In order to meet that purpose, suggestions on five areas in consolidation financial statement are proposed. Those five aspects are as follows: Area of SPE Consolidation, Area of internal transaction setoff, Area of unrealized gain or loss setoff, Area of eliminate the investment account against the stockholder's equity, Making Consolidation footnote and Consolidation CoA as other area.

As increasing demands for a floating structure expanded from offshore industry facilities to living facilities, it has emerged that necessity of techniques to reduce motions of a floating structure. This study present a floating structure with porosity on the outer surface of the floater. Under each regular and irregular wave, responses of the floater was investigated in frequency domain. The proposed structure is composed of inner and outer floaters, which are connected to each other and the outer wall is perforated, and the heave and the pitch of floaters with different perforation rates (0~30%) were compared with at both the center and the edge. The results showed that pitch responses can be decreased by increasing of perforation rate of the floater. Comparing with responses of the non-perforated floater, those of the proposed floating structure were reduced to above 10% and 2%, respectively for regular and irregular wave conditions.
