  • A number of the retail and traditional market customer is decrease, whereas that of the supermarket in department-store customers is increase. This case suggests that customers have a preference for much more comfortable and pleasant shopping places And making a reasonable purchase in the supermarkets where we can find various goods and price zone, is now garden variety. It is a current course that once the manager ask an architect for multi-functional space design in department-store and then the architect compose a team and start to design. Of course, the team of planner thinking manage give the design team the basic material data such as commerce analysis and the use of each layer in the department store but, the design team solve the assignment by architectural form, functional space plan and the limited architecture law, After establishing general design for architecture, we can ask shopping-mall distribution, products display and interior design of the interior design team. so it is inevitable that the interior design team concerning M$\cdot$D can find lots of complementary factors with architecture design. The purpose of this study is analyzing the differences of architecture design, which has to accept the limited law and interior design concerning M$\cdot$D, satisfying the structure and the law in the future design for the department-store. Also the purpose of this thesis is suggestion the items architects and interior designers research into together to make the inner space ideally.

  • 교육부의 운영계획에 따라서 학교당 1~2개 교실에 전자칠판(IWB, Interactive White Board)이 보급되었다. 따라서, 두상투영기(OHP, Overhead Projector)와 스크린 대신에 실물화상기와 전자칠판이 그 역할을 대신하게 되었다. 하지만 촬상소자와 디스플레이 장치의 발전 속도를 따라가지 못하고, 활용도가 떨어지는 경우가 많았다. 본 연구에서는 스마트폰의 카메라를 이용하여 고해상도의 이미지를 획득할 수 있도록 연구한다. 획득한 고해상도의 이미지를 전자칠판이나 대형 TV로 무선 통신으로 지연시간 없이 전송할 수 있도록 와이기그(WiGig, Wireless Gigabit) 기술을 이용한다. 또한 스마트폰 카메라에 넓은 화각(FOV, Field of View)의 렌즈를 탑재하여 출시하는 것에 반하여, 현미경 렌즈를 이용하여 스마트폰으로 특정 부분을 400배까지 확대하여 관찰할 수 있도록 한다. 본 연구결과로 교육 및 연구 현장에서 실시간 400배 확대의 활성화 자료로서 사용될 것이다.

  • Expansive soil is the most predominant geologic hazard which shows a large amount of shrinkage and swelling with changes in their moisture content. This study investigates the macro-mechanical and micro-structural behaviours of dredged natural expansive clay from coal mining treated with ordinary Portland cement or hydrated lime addition. The stabilised expansive soil aims for possible reuse as pavement materials. Mechanical testing determined geotechnical engineering properties, including free swelling potential, California bearing ratio, unconfined compressive strength, resilient modulus, and shear wave velocity. The microstructures of treated soils are observed by scanning electron microscopy, x-ray diffraction, and energy dispersive spectroscopy to understand the behaviour of the expansive clay blended with cement and lime. Test results confirmed that cement and lime are effective agents for improving the swelling behaviour and other engineering properties of natural expansive clay. In general, chemical treatments reduce the swelling and increase the strength and modulus of expansive clay, subjected to chemical content and curing time. Scanning electron microscopy analysis can observe the increase in formation of particle clusters with curing period, and x-ray diffraction patterns display hydration and pozzolanic products from chemical particles. The correlations of mechanical properties and microstructures for chemical stabilised expansive clay are recommended.

  • Under the influence of postmodernism, modern writing tends to refuse an immediate conveyance of messages achieved by linear, unified writing. Such writing does not attempt any social participation and has no leading ethics, offering diverse perspectives. It simply relies on material property ignoring the 'here and now'. This discussion depends on the sensuous immediacy of works that are pure and uninterpretable, causing the "death of author" phenomena. Although the time was late, since the 1990s, discussion and work on deconstructive theater has been executed in the Korean theater world. This deconstructive work was achieved when lineal narratives were shattered through the shocking insertion of fragmentary episodes and imagery. Moreover, such plays were shocking presentations of severance in conversation; lack of communication; loss of pride and love; and a world devastated by violence and madness. In the 2000s, such a movement helped form a new paradigm in the theater through reinterpretation and parody of traditional dramas, while drawing general attention to postmodern theater. However, as the problems of postmodern theater are perceived through study, the limit of plays with a postmodern tendency is pointed out: such plays merely display 'deconstruction'. This thesis will examine reflective thought on postmodern theater seeking "deconstruction without alternatives" and the aesthetic concept of "le politique" by Jacques Ranciere. It will also look through the overlap of images as interval-estrangement, "lettre morte", and simulacre representing mise-en-scene aesthetics weaving "political writing". This study is meaningful in that it tries to extend the new aesthetic horizon of Korean theater, examining in 2009 and by Koh Sun-Woong in 2011, directed by Park Chung-Hee in 2010 and directed by Park Keun-Hyung in 2009.

  • The sustainable development principle of replacing natural resources with renewable material is an important research topic. In this study, waste LCD (liquid crystal display) glass powder was used to replace cement (0%, 10%, 20% and 30%) through a volumetric method using three water-binder ratios (0.47, 0.59, and 0.71) to make cement mortar. The compressive strength was tested at the ages of 7, 28, 56 and 91 days. The test results show that the compressive strength increases with age but decreases as the water-binder ratio increases. The compressive strength slightly decreases with an increase in the replacement of LCD glass powder at a curing age of 7 days. However, at a curing age of 91 days, the compressive strength is slightly greater than that for the control group (glass powder is 0%). When the water-binder ratios are 0.47, 0.59 and 0.71, the compressive strength of the various replacements increases by 1.38-1.61 times, 1.56-1.80 times and 1.45-2.20 times, respectively, during the aging process from day 7 to day 91. Furthermore, a prediction model of the compressive strength of a cement mortar with waste LCD glass powder was deduced in this study. According to the comparison between the prediction analysis values and test results, the MAPE (mean absolute percentage error) values of the compressive strength are between 2.79% and 5.29%, and less than 10%. Thus, the analytical model established in this study has a good forecasting accuracy. Therefore, the proposed model can be used as a reliable tool for assessing the design strength of cement mortar from early age test results.

  • 본 연구에서는 대장균 세포 표면에서 발현되는 유기인분해효소(organophosphorus hydrolase; OPH)를 이용하여 난분해성 및 환경독성물질로 알려진 diazinon의 효과적 처리가 이루어졌다. 이 실험에서는 $25^{\circ}C$ 배양 온도와 배지에 0.2 mM ethylenediamine tetraacetate (EDTA) 첨가 조건이 유기인분해 효소 생산에 효과적임을 알 수 있었다. 이 조건에서 성장한 대장균을 이용하여 초음파 파쇄공정이 수행되었을 때, 25, 50 mg/L diazinon는 각각 4.5, $7.2mg/g{\cdot}min$의 diazinon 제거 속도를 나타내었고, 두 농도(25, 50 ppm) 모두 90% 이상 제거 효율을 구할 수 있었다. 따라서 이러한 실험 결과들은 diazinon과 같은 독성 화합물을 친환경적으로 처리할 수 있는 생물학적 처리 시스템으로 활용될 수 있을 것이다.

  • The distribution and prediction interval for the misorientation angle of grain boundary at which $Cr_2N$ was precipitated during heating at $900^{\circ}C$ for $10^4$ sec were newly estimated, and followed by the estimation of mathematical and median rank methods. The probability density function of the misorientation angle can be estimated by a statistical analysis. And then the ($1-{\alpha}$)100% prediction interval of misorientation angle obtained by the estimated probability density function. If the estimated probability density function was symmetric then a prediction interval for the misorientation angle could be derived by the estimated probability density function. In the case of non-symmetric probability density function, the prediction interval could be obtained from the cumulative distribution function of the estimated probability density function. In this paper, 95, 99 and 99.73% prediction interval obtained by probability density function method and cumulative distribution function method and compared with the former results by median rank regression or mathematical method.

  • The basic properties and electrical characteristics of sputtering films deposited with a commercial cast target and spark plasma sintering (SPS) were compared and analyzed. The results, revealed that, the Al film prepared by heating at $60^{\circ}C/min$ (SPS process) showed a specific resistance similar to the commercial cast Al film. In addition, the results of XRD, SIMS and TEM, showed that there was not much difference in the crystal structure and impurities between the two films. Consequently, the SPS Al target was found to have properties quite similar to the commercial one and it is expected to be applied in future research to the metal wiring material for semiconductor/display devices.
