As sustainable design technologies, advanced daylighting systems with lightshelves have been developed and are currently under monitoring the daylighting performance. This study aims to evaluate the comparative daylighting performance of sloped lightshelf and conventional glazing window with mock-up model, reconstructed as a prototype of Korean office building, sized $12.0m{\times}7.3m{\times}3.7m$ ($w{\times}d{\times}h$) and $1.8m{\times}4.8m$($w{\times}h$) for the south facing side-window was installed on the rooftop of engineering building, Kyung Hee University in Korea. It has an identical configuration of reference room and the test room. For the test room, the sloped type lightshelf system was designed as 10mm transparency sheet glass, tilt angle degree $29^{\circ}$, and total sized 1.28m (interior length 0.88m, exterior length 0.49m). It consisted of daylighting collector, entrance glazing and reflector. To assess daylighting performance, the totally 37 measuring points for illuminance and 2 view points of luminance were monitored in every 30 minutes from 12:00 to 15:00. For the detailed analysis, photometric sensors of each room were installed at work-plane (8 points), wall (7 points), ceiling (3points), and exterior horizontal illuminance (1 point). Luminance of window, rare of the room was measured under clear sky. It is to be monitored by Agilent data logger, photometric sensor Li-cor and the Radiant Imaging ProMetric 1400. Comparisons with a light factor, increase-decrease ratio, uniformity, and luminance are discussed.

Demands for geriatric hospital have increased in an era of rapidly aging population. Most of aged patients tend to stay in institutions for long terms. This means that the patient rooms of geriatric hospital should be given different considerations from those of normal hospital in designing interior features. They should be a homelike places for the aged patients and designed to take care of specific needs of the aged. However, most of geriatric hospitals are designed with little attention to such point. They appear almost same to normal ones. This study attempts to examine how users evaluate patients' rooms. The users are nurses, care-givers and family members of aged patients in six geriatric hospitals in Busan. They rated 12 features of patient rooms from 0 point to 100 points and described reasons why they rated in that way. Also, the walk-through was done for these six hospitals. 12 features are sizes of patient rooms, sizes and fixtures of bathrooms, sizes and locations of windows, bed layout, numbers and types of chairs, sizes and types of closet, lighting, color scheme, finishes of floor and wall, and interior design tone. Followings are findings : The users evaluated patients' rooms relatively positive. However, extra chairs for visitors, closet in patients rooms and storage in bathroom, and sizes of patients rooms and bathrooms were evaluated relatively negative.

Architectural color would be understood as a essential tool to be reflected the architect's value criteria, thinking process and the specific methodology. This study was established the characteristics of color use correlated with Eisenman's architectural features based on his point of view. At first, it could be organized with data and use the color in view points with the becomming process. Especially it would be expressed the color as a trace of unsynchronized formation. Second, it was introduced the color by graphics engaged with form, to be expressed the dividing, folding, reiteration for deliver of escape from graphic thinking process. Third, it was analyzed to be imported the color to have a multi-lateral space experience in center of user's space recognition and behavior by introduction of color. Finally, it could be inducted the consistent color by viewpoint of interfacial between interior and exterior environment, communicated with strong meaning by conversion from interior elements to color from these processes. A characteristics of Eisenman's architecture color is reflected his thinking process in architecture color as it is and can be understand of 'becomming process use of color' as a tool that is corresponded in form creation. Specially, it would be kept continuous viewpoint of interior and exterior space, giving user color as a viewpoint of linking space, enable many-sidedness experiences through space.

The purpose of this study was on suggesting what is the image and image formation factor of interior landscaping plants. For this purpose, the sixty interior landscaping plants were selected. Selected plants were classified into 9 groups by similar characteristics of plants, for example, leaf color and leaf pattern. Data analysis were performed by semantic differential scale method, mean score and multiple regression algorithm. The results are as follows, 1. Comparing with image assessment, group 9 got the highest score in all aspects. 2. Comparing with the image assessment of interior landscaping plants, the "impressive" image was obtained the highest score and "bright", "cool", "beautiful" and "fresh" were followed. 3. Multiple regression analysis was performed to clarify influence degree of the adjectives related to the beauty. The next adjectives were significant check points on assessing the beauty of interior landscaping plants. Also, Guzmania magnifical was investigated to have the most beautiful image with the results of preference analysis. Vriesea splendens, Cordyline terminalis Kunth 'Lilliput' and Peperomia sandersii were identified as considerably preferred plants. were identified as considerably preferred plants.

최근 1인 가구 수의 급증으로 인해 셀프 인테리어에 대한 관심이 높아지고 있다. 인테리어 중에서 가장 큰 비중을 차지하는 것은 가구 배치이다. 그런데 간혹 적정한 위치에, 공간을 효율적으로 활용할 수 있는 위치에 가구를 배치하기 위해 전문가의 도움이 필요한 때가 있다는 것이 셀프 인테리어의 단점이다. 이런 상황에서 사람들은 개인 SNS를 통해 인테리어에 대한 정보를 공유하거나 조언을 주고받으며, 전문가에게 직접 도움을 받기도 한다. 하지만 이러한 방법들은 2D 사진이나 영상을 통해 공간을 보기 때문에 세밀하고 정확한 조언이 어렵거나, 전문가가 직접 방문을 해야만 하는 시간적, 물리적 번거로움이 있다는 단점이 있다. 본 논문에서는 이러한 단점을 보완하기 위해 가상현실 상에서 실시간으로 가구 배치를 공유할 수 있는 애플리케이션을 제안한다. 제안하는 애플리케이션을 통해 인테리어에 관한 정보와 조언을 더 생생하고 정확하게 공유할 수 있으며, 실시간으로 공유가 되기 때문에 두 사용자의 시간과 체력의 소비가 최소한으로 줄어들 수 있을 것으로 예상된다.

Contemporary Architecture stands on the basis of the influence of the formative arts, and it carves out a new field of architecture through various technical or material expressions. Herzog ＆ de Meuron, whose has been recognized internationally, are one of few artists following this Contemporary architectural flow. This thesis analyzed his work of art by the trend of times, and base on the results, tried to find his architectural language. Three points have been concluded through this architectural thesis. The architectural language does not deal with our monotonous environment, but deals with it technically. It's expressed all the architectural factors that we already know and used through new ways, so that, finally, it makes people feel the work of art in different point of views. I desire more future researches will focus on the many types of architectural and interior design languages that the Contemporary society craves.

This study concentrates on a new idea that is formulated as a creative space recognition in contemporary architecture and painting. It is stimulated from Deleuze's philosophy, which is expressed with the philosophical instrument, "Non-Representation". After discussing the concept of non-representation used in Deleuze's philosophy, case example in contemporary architecture are analysed to comparatively Investigate the relationship between the architectures by Rem Koolhaas and painting by Francis Bacon. Therefore, he founds expressions of "diagram" and "movement" in painting of F. Bacon. Diagram meansit is a power that is comprised of various points of wiew with the kind experiences that one has in life. Movement that were extracted form the Instrument in space recognition of Deleuze's panting theory were of topology, insertion of geometry, reiteration of layers, transparency and translucency, reflection effect.

Finding an initial feasible solution on the central path is the main difficulty of feasible interior-point methods. Although, some algorithms have been suggested to remedy this difficulty, many practical implementations often do not use perfectly centered starting points. Therefore, it is worth to analyze the case that the starting point is not exactly on the central path. In this paper, we propose a weighted-path following interior-point algorithm for solving the Cartesian $P_{\ast}({\kappa})$-linear complementarity problems (LCPs) over symmetric cones. The convergence analysis of the algorithm is shown and it is proved that the algorithm terminates after at most $O\((1+4{\kappa}){\sqrt{r}}{\log}{\frac{x^0{\diamond}s^0}{\varepsilon}}\)$ iterations.

The main objective of this study is to estimate location and strength of sound sources distributed on the surface of an enclosure. Acoustic holography method has been used to identify the sources in an interior sound field. However, it can not completely distinguish between the direct sound field from sources and the reflections from surfaces. The method just reconstructs the entire sound field based on the sound pressure at the finite number of measurement points. In this stduy, a method which estimates only the active sources by using measurements of field pressure and surface admittance is proposed. An in-situ technique to estimate the general boundary condition is also proposed by using acoustic holography, assuming the surfaces are locally reacting.
