이상우(Lee Sang-Woo) 한국어문학회 2010 語文學 Vol.0 No.110

This article examine the relation between Korea’s division system and the films of Shin Sang-ok, who was one of very famous Korean film directors in the golden age of Korean cinemas. Shin Sang-ok has been maybe the only Korean director, who produced his films in two Koreas. Before he was kidnapped by North Korean kidnap gangs, he was an outstanding film director in South Korea, who produced several popular films, as like 〈A Romance Papa〉, 〈King Yeonsan〉, 〈the evergreen tree〉, 〈a guest and mother)〉, 〈the Red muffler〉, and so on. Also, He managed the biggest film company ‘Shin Film’ and the biggest film studio ‘Anyang Film Studio’ in South Korea in 1960s, he maintained to good relation with the president Park Chung-hee’s government at that time. However, as Shin criticized the film policy of Park Chung-hee’s government, especially the problem of film censorship, the conflicts between them went to worse way in 1970’s. And then Shin was kidnapped with his ex-wife a famous Korean film actress Choi Eun-hee to North Korea. Shin abd Choi stayed in there during the 8 years and produced 7 films in North Korea’s Monolithic Ideal Logical System by Kim Jung-il’s enforcement and immense supports. At that time, Shin produced several remarkable films in North Korea, as like 〈not returned the emissary〉, 〈the salt〉, 〈a story of the escape〉. Finally, Shin and Choi escaped from North Korea for obtaining the freedom to the Western world. Two Koreas’s division system brought the restriction of creative film making to a film director Shin Sang-ok.

최근 각종 교통소음 공해의 심각성과 주민들의 생활의 질에 대한 요구는 나날이 높아 가는 추세이다. 따라서 소음영향평가 및 소음조절 방안수립에 대한 연구의 필요성이 절실히 요구된다. 본 연구에서는 문헌고찰 및 실측을 통하여 선진 외국의 고속열차에 대한 소음의 물리적 특성을 규명한 후, 국내에서 최초로 건설되는 고속철도 전용역사인 C 종합역사를 대상으로 외부환경 소음도를 평가하였다. 이는 향후 국내 고속철도 개통에 따른 소음영향의 제반 문제점 및 개선방향과 역사 건물 실내외의 소음방지 대책을 수립하는데 주요 기초 자료로 활용될 수 있을 것으로 판단된다. With the increase in discomfort of living by serious traffic noise pollution, the desire of relieving from discomfort is boosted up more than ever. For this reason, the researches on environmental impact assessmient and noise pollution control are highly required. This research was aimed to analyze the physical characteristics of noise caused by high-speed train in foreign countries by literature survey and field data. And with the attained results, the exterior noise level around Chon-An station, the first station planned for the high-speed train in this country, was estimated. The results of this study might be used as a tool for predicting the unavoidable noise, lessening the noise impact caused by the high-speed train, and preparing the noise prevention measures for the interior space and the exterior around stations.

In recent years, understanding the dynamics of DC distribution system has become critically important due mainly to the increasing needs for the interconnection of DC distributed generators and the (DC-based) electric vehicle (EV) charging systems. In this paper, the characteristics of the DC grid system connected to the compact proton exchange membrane fuel cell (PEMFC) has been studied. In particular, the voltage and current transient phenomena were measured by varying the load of the DC grid system. Also, the voltage and current ripple were measured at the different load conditions. Our experimental results clearly manifested that the study contributes to the establishment of fundamental method to characterize the small DC grid system including distributed generation.

Block based transform coding is most popular approach for image and video compression. However it suffers from severe quality degradation especially from blocking artifacts. The subjective quality degradation caused by such blocking artifacts in general does not agree well with an objecive quality measurement such as PSNR. Hence new quality evaluation technique is necessary. We propose a new image quality assessment method by measuring blocking artifacts for block based transform coded images. In order to characterize blocking artifacts, proposed method utilizes the facts that, blocking artifacts, when occur, have different pixel values along the block boundaries and such differences usually continuously span along the whole boundaries. This method does not require the original uncompressed image. It operates on single block boundary and quantifies the amount of blocking artifacts on it. Experiments on various compressed images various bitrates show that proposed quantitative measure of blocking artifacts matches well with the subjective quality of them judged by human visual system. 블록 기반의 변환 부호화 방식은 영상 압축 표준에 널리 사용되고 있다. 이러한 방식에서 발생하는 여러 종류의 화질 열화 현상 중 블록의 경계에서 나타나는 블록화 현상은 화질을 떨어뜨리는 대표적인 요인이다. 블록화 현상에 의한 화질 열화는 기존의 PSNR 같은 화질 측정값과 부합하지 않아 새로운 평가 기법의 개발이 필요하다. 본 논문은 블록 기반 변환 부호화 방식으로 압축된 영상에서 블록화 현상이 발생한 정도를 측정하여 화질을 평가하는 새로운 기법을 제안한다. 본 논문에서 제안하는 기법은, 블록화 현상이 블록 경계에서 발생하면 경계면에서 양쪽 화소의 밝기값의 차이가 나며, 대개 그 길이가 블록의 경계 길이 만큼 이어지는 특징을 이용하여 블록화 현상을 찾아낸다. 본 논문에서 제안하는 방법은 원본 영상이 필요치 않고, 블록 경계에서 동작하며, 블록화 현상의 발생 정도를 수치화 한다. 다양한 압축 영상에 본 기법을 적용한 결과, 제안하는 블록화 현상 평가 수치는 인간의 시각 특성에 기반한 주관적 화질 평가와 부합하는 것을 확인하였다.

공간성, 호소유형 및 형태복잡도 지수를 이용한 토지이용과 호소수질의 관계 연구

Land use types within a watershed closely are related with the water quality characteristics of receiving water bodies. Despite of a numerous studies suggesting a strong relationship between water quality and land use, there have been increasing concerns about the geographical variation and a lack of spatial integration in that relationship, which are essential to implementing these findings into land use planning and management. In the meantime, edges mediate the material flux between adjacent systems. This mediating effect of edges is strongly related to the complexity of their shapes. Land use activities within a watershed have a direct impact on the water quality of adjacent aquatic systems, and hydrological processes carry residuals from watershed into adjacent aquatic ecosystems through the edges. Therefore, the geometry of reservoirs theoretically affects the relationship between land uses in the watershed and the quality of receiving bodies of water. In this light, this study integrates the geo-spatial dimensions of land uses in the watershed using GIS and landscape indices in order to explore the relationship between land uses and water quality. Water quality characteristics, land uses and geometry of 133 randomly sampled reservoirs were correlated, based on buffer zones and types of reservoirs. The findings showed that land uses, particularly urban land uses, significantly affect water quality characteristics including BOD, COD, TN and TP, and geometry of reservoirs reduces the concentration of pollutant and nutrients in reservoirs. One of results indicates that the relationship between land use and water quality and effects of spatial dimension may vary with types of reservoirs and pollutants. These results suggest that lakeshore areas are important, particularly for TN reduction and call for a caution to land use activities nearby shoreline areas for sustaining better water quality.

이상우,김광호,이원종,Lee, Sang-Woo,Kim, Kwang-Ho,Lee, Won-Jong 한국전기전자재료학회 1998 전기전자재료학회논문지 Vol.11 No.2

The $LiNbO_3$ thin films were prepared directly on Si(100) substrates by conventional RF magnetron spurttering system for nonvolatile memory applications. RTA(Rapid Thermal Annealing) treatment was performed for as-deposited films in an oxygen atmosphere at 600 $^{\circ}C$ for 60 s. The rapid thermal annealed films were changed to poly-crystalline ferroelectric nature from amorphous of as-deposition. The resistivity of the ferroelectric $LiNbO_3$ film was increased from a typical value of $1{\sim}2{\times}10^8{\Omega}{\cdot}cm$ before the annealing to about $1{\times}10^{13}{\Omega}{\cdot}cm$ at 500 kV/cm and reduced the interface state density of the $LiNbO_3/Si$ (100) interface to about $1{\times}10^{11}/cm^2{\cdot}eV$. Ferroelectric hysteresis measurements using a Sawyer-Tower circuit yielded remanent polarization ($P_r$) and coercive field ($E_c$) values of about 1.2 ${\mu}C/cm^2$ and 120 kV/cm, respectively.

본 연구는 대구광역시의 주요도로를 대상으로 공간통계기법을 이용하여 도로교통 온실가스 배출량을 신뢰성있게 예측하여 추정된 배출량으로 행정구별에 따라 도로교통에서 발생한 온실가스 배출량을 산정하는 것을 목적으로 하였다. 첫째, 주요도로의 교통량 관측지점에서 실시간으로 조사한 교통량을 이용하여 관측지점에서 발생한 온실가스 배출량을 산정하였다. 둘째, 일반 크리깅(Universal Kriging)기법을 이용하여 공간적 상관성에 의해 미 관측지점의 온실가스 배출량을 신뢰성 있게 추정하기 위해 적합한 베리오그램 모델링을 설정하였다. 이에 교차검증을 통하여 적합한 베리오그램 모델과 크리깅 기법의 타당성을 검증하였다. 셋째, 검증된 크리깅 기법으로 미 관측지점의 도로교통에서 발생한 온실가스 배출량을 예측하여 행정구별로 도로교통 온실가스 배출량을 추정하여 산정하였다. 그 결과, 도로교통 온실가스 배출량을 행정구별로 보면 북구가 약 $291,878,020kgCO_2eq/yr$로 가장 많은 온실가스를 배출하는 것으로 나타났다. This study was intended to reliably predict the traffic green house gas emission in Daegu with the use of spatial statistical technique and calculate the traffic green house gas emission of each administrative district on the basis of the accurately predicted emission. First, with the use of the traffic actually surveyed at a traffic observation point, and traffic green house gas emission was calculated. Secondly, on the basis of the calculation, and with the use of Universal Kriging technique, this researcher set a suitable variogram modeling to accurately and reliably predict the green house gas emission at non-observation point suitable through spatial correlation, and then performed cross validation to prove the validity of the proper variogram modeling and Kriging technique. Thirdly, with the use of the validated kriging technique, traffic green gas emission was visualized, and its distribution features were analyzed to predict and calculate the traffic green house gas emission of each administrative district. As a result, regarding the traffic green house gas emission of each administration, it was found that Bukgu had the highest green house gas emission of $291,878,020kgCO_2eq/yr$.
