The purpose of this study is to investigate the characteristics of ethical consumption in the Community Currency Movement participant's daily life as a consumer. Qualitative research methods are used for the understanding about the participation activities and the daily lives as a consumer of Hanbat LETS participants'. The characteristics of ethical consumption used for analysing of the Community Currency Movement are the subjective participation, production process-aware consumption, others care to consumption, sustainable consumption, voluntarily simple life. The major results of this study show that the Community Currency Movement is the alternative economic system practicing the ethical consumption. The Community Currency Movement increase the subject participation, realize the social responsibility and community society and the ecological value and voluntary simple life. This research get the meaning for considering the Community Currency Movement & the ethical consumption on the discriminatory perspective.

In the usual dry etching process for the TFT-LCD fabrication, it is hard to monitor the basic plasma parameters such as density and temperature. However, the basic parameters are easily monitored during the dry etching process. We have simultaneously measured the electric characteristics and basic plasma parameters of the dry etching chamber during the process, analyzed them to interpret plasma parameters. For the Ar plasma discharge case, we could obtain the density and temperature from the electric characteristics using a simple simple sheath model.

The objective of the study is to understand the characteristics of modernistic spatial design and, based on the understanding, to interpret fashion in terms of its spatial relationship with society, culture and human body, thereby looking into unique spatial characteristics fashion has. The main results of this study include : First, the rational space emphasizes geometric symmetry and harmony among each of design elements and is expressed by pursuing a perfect formative beauty that indicates an eternal formal beauty of a physical space. In addition, functional beauty is also pursued, making clothing convenient for activities. Second, the abstract space is characterized as a kind of purity by emphasizing simple patterns and colors and materials of purity for clothing, and it is sometimes expressed as being extremely abstract so that human body can be shown to be distorted. Third, for the uniform and neutral space, mass-production and production at home was made possible with clothing of simple patterns and of standard. In addition, it showed a tendency to become blurred in gender distinction for clothing with women wearing men's clothing, or borrowing design elements from men's clothing. Forth, the space as means of domination and control was shown to be segmented based on place, function and purpose. In addition, control on physical beauty was shown by promoting slim figures that are suited for lineal silhouette of clothing and circumstantial restriction on clothing occurred during war, serving to limit the styles of and purchase of clothing.

Recently, Townhouse has emerged as a blue ocean of real estate market in Korea. In designing town houses, which are luxurious suburban houses centered around the capital area, the construction companies are using 'designer marketing' in which they hire interior designers and architects and express various styles of design in the interior space of the town houses. Therefore, this study examined the unit-family cases of Korean townhouses and analyzed the expression characteristics of design in the interior space of the town houses built after 2000 in terms of their spatial, morphological, material, and color aspect. "The extensibility of space" and "variableness of space" seem to have the same meaning, but they turned out to be not related to each other due to the particularity of houses. "The extensibility of space" turned out to show its characteristics via "the use of transparent materials." "Minimal form" utilizes the unified "achromatic and simple colors" to emphasize the simplicity and in some cases, highlights the use of original colors. The interior space of the townhouses expresses the traditional or heterosexual oriental image through "the use of natural materials," and they point out the "oriental form" through the controlled beauty expressed by using oriental components and "achromatic and simple colors."

A directly coupled Boundary Element and Finite Element Model was applied to the dynamic analysis of a coupled acoustic silencer with vibratory wall. In this cupled BEM-FEM muffler model, the BEM model was used to discretize the acoustic cavity and the FEM model was used to discretize the vibratory wall structure. Then the BEM model was coupled with the FEM model. The results of the coupled BEM-FEM model for the dynamic analysis of the simple expansion type reactive muffler configurations with flexible walls were verified by comparing the predicted results to analytical solutions. In order to investigate the effects of the muffler's structural flexibility on its transmission loss(TL) characteristics, the results of the coupled BEM-FEM model in conjunction with the four-pole parameter theory were utilized. The muffler's TL characteristics using the BEM-FEM coupled model with flexible walls as compared to other muffler configurations was studied. Finally the muffler's TL values with respect to different wall's thickness are predicted and compared.

국내의 사면붕괴는 대부분 우기 또는 해빙기에 집중적으로 되고 있는 실정이며, 이에 따라 최근의 강우시 토사사면의 설계기준은 보수적인 관점에서 지표면에 지하수를 위치시켜 놓고 사면안정성을 평가하고 있어 설계자의 관점에서 볼 때 지나치게 보수적인 경향이 있다. 그러나 강우시 토사사면을 합리적으로 설계하기 위해서는 강우조건 및 토사사면의 불포화 특성을 고려하여야 하며 이를 위해서는 토사사면의 불포화 특성을 파악하기 위한 실내시험 및 강우조건에 따른 침투류 해석 등이 수행되어야 하는 어려움이 있어 보수적인 관점에서 기존의 설계기준에 따라 토사사면의 설계가 이루어지고 있는 실정이다. 따라서 본 연구에서는 별도의 침투류 해석 없이 강우시 토사사면의 불포화 특성을 고려한 간편 설계법을 제안하고자 하며, 이에 대한 검증으로 실제 붕괴된 토사사면을 대상으로 현행 설계기준에 의한 설계방법과 침투류 해석에 의한 설계방법에 대한 비교연구를 수행하였다. 비교검증 결과 현행 설계방법은 지나치게 보수적인 설계방법임을 확인하였으며, 본 연구의 간편 설계법이 강우시 토사사면의 안정성을 평가하는데 있어서 현행 설계방법에 비해 합리적인 것을 알 수 있었다.

본 연구의 목적은 초고층 복합건물 공사에서 마감자재 양중횟수를 산정하는 약산식을 제안하는 것이다. 그것은 양중계획 시 효율적인 데이터로 활용될 것으로 기대된다. 마감자재 양중계획은 건물이 고층화 될 수록 더욱 더 중요해 진다. 양중횟수는 "패키기"라는 방식을 통하여 기존의 방식보다 더욱더 정확하게 산정할 수 일다. "패키지"는 마감자재별 특성을 고려하여 한번에 양중할 수 있는 마감자재별 양중형식을 고려한다는 것을 의미한다. 도출된 약산식은 기준층 바닥면적과 단위면적당 실갯수라는 두 요소를 변수로 하여 도출하였다.

For the development of 100[W] stage lighting, quantitative and uniform color mixing that applied through color adopted Simple-Inverse matching so that color mixing can be possible along Black Body Locus. R,G,B(Red, Green, Blue) LED(Light Emitting Diode) arrangement through LED package character analysis, LED module, and the characteristic of device were considered for uniform color mixing. A distance changeable optical device was built to assure high uniformity and high diffusion of not only the middle of diffusion side but also the border side. Also, we developed the control power circuit that can expand up to 6 channels which are possible for quantitative color mixing, and the high uniformity and high quantified border light for color mixing control and the verification of color mixing characteristics by composing GUI(Graphical user interface) including color mixing simulator. By presenting the experimental results of light color control, we proved the usefulness of our developed border light and the proposed color mixing method.

Data races are one of the most difficult types of bugs in concurrent multithreaded systems. It requires significant time and cost to accurately detect bugs in complex large-scale programs. Although many race detection techniques have been proposed by various researchers, none of them are effective in all aspects. In this paper, we compare the performance of five recent dynamic race detection techniques: FastTrack, Acculock, Multilock-HB, SimpleLock+, and causally precedes (CP) detection. We experimentally demonstrate the strengths and weaknesses of these dynamic race detection techniques in terms of their detection capability, running time, and runtime overhead using 20 benchmark programs with different characteristics. The comparison results show that the detection capability of CP detection does not differ from that of FastTrack, and that SimpleLock+ generates the lowest overhead among the hybrid detection techniques (Acculock, SimpleLock+, and Multilock-HB) for all benchmark programs. SimpleLock+ is 1.2 times slower than FastTrack on average, but misses one true data race reported from Mutilock-HB on the large-scale benchmark programs.

본 논문에서는 확대 영상의 화질을 개선하기 위하여 인접픽셀 값 정보를 이용하여 영상의 단순 볼록 곡면과 단순 오목 곡면을 추정하는 기법과 영상이 단순 볼록 곡면과 단순 오목 곡면의 특성을 반영하여 확대 영상을 구성하는 기법을 제안하였다. 제안된 기법을 사용하여 확대 영상을 구성하면 기존의 기법들을 사용하여 확대한 영상보다 실제 영상에 더욱 충실하게 된다. 제안된 기법을 적용하여 확대한 영상의 화질향상 정도를 측정하기 위하여 PSNR(Peak Signal to Noise Ratio)을 사용하였다. 제안된 기법을 적용하여 확대한 영상들의 PSNR 값들은 기존의 기법들을 적용하여 확대한 영상들의 PSNR 값보다 큰 것을 확인하였다.
