The purpose of this study is to find out the way of embodying architectural concept in Nussbaum Museum for complementing present abstract and generalized research. This study tries to examine the close relationship between a certain concept and Nussbaum museum through analyzing architectural characteristics and searching its principles by concrete application of concept. The Architectural concept "Museum without exit", which Libeskind applied to Nussbaum Museum, is based on the dramatic life of Jewish painter Felix Nussbaum with relation to Holocaust, physical background of site and features of program, Libeskind Applied his architectural concept from the beginning to the most parts of the museum. His new museum subverts notions and logic of general features of existing museums. Libeskind's architectural concepts are especially applied to site plan, massing, circulation and spatial configuration. "Museum without exit" creates labyrinth like circulation based on stories including Nussbaum's life, his painting tendency and circumstances of those days. It also realize sensuous space through spatial shape and light control. Although some critics criticize that this museum is not suitable for paint collection because of overwhelming strength of architectural space. However, considering this museum's function of a kind of Holocaust museum beyond personal art gallery, Libeskind's 'museum without exit' shows effective realization of architectural concept for Jewish painter Felix Nussbaum's museum.

The purpose of this comparative study is to analyze the characteristics of art museums of Louis I. Kahn. Kahn's main architectural thoughts of 'what it wants to be' and 'how it was done' act as a basis for this research. 'What it wants to be' means the existence of architecture and relates to the concept of 'room'. 'How it was done' shows the tectonic aspects of architecture and construction process to enhance its presence. Detailed items from these two thoughts applied to clarify the order in dynamics, the visualization of construction process, and the relationship between structure and light in the space of Kahn's art museums. Yale university art gallery was the first major project of Kahn and he showed tectonic characters through tetrahedral concrete slab. The unity of structure, space and light can be found in the Kimbell art museum through the vaulted structural unit. Yale center for British art is the best example of the concept of 'room' and 'tectonic' because it clearly shows the unity of spatial and structural system, and their relation to light. As a result, this study tries to find out that Kahn had consistently developed his thoughts of'room' and 'tectonic', and tried to keep them in his art museum designs.

Aldo Van Eyck and Herman Hertzberger explained 'In-between space' as an intermediate space between opposite elements such as whole and parts, inside and outside, open and close, central and decentral. From this idea, the meaning of 'in-between space' has developed and applied to works of Bernard Tschumi and Sou Fujimoto. In this study, the meaning of 'in-between space' was compared and analyzed based on two architects' works to reveal the design approach in terms of 'in-between space' Final Wooden House, N House, and Serpentine Gallery Pavilion among Sou Fujimoto's work were selected and Le Fresnoy, Lerner Student Center, and Acropolis Museum among Bernard Tschumi's work were selected to analyze. To understand their design approach, their works were compared and analyzed in architectural attitude, tools, construction style and the approach, concept, theme, relation, direction of in-between space. As a result, Sou Fujimoto uses 'in-between space' as a nebulous approach as intermediate space between opposite elements. For Bernard Tschumi, 'in-between space' is also an intermediate space to emphasize and make a tension between opposite elements. It is a method of solving the contradiction condition between old city environment and new architecture.

As a link in the chain of antidrought measure, our attempt is made to obtain basic informations on the construction of an infiltration gallary which can be supplied with irrigation water by catching of underground water in small river beds, which is economical, permanent and efficient. The experiment was made, concerning the structure of catchment conduits, by constructing a model sand tank $1.5m{\times}5m{\times}1.5m$ in dimension made of reinforced concrete. Various kinds of measuring equipment were attached to the model tank which contains a set of catchment conduits, each of them was made 30cm in diameter and 60cm in length with the ratio of sectional area to total area of influx holes 10:1, 20:1, 30:1. The average size of influx holes was fixed from 0mm to 10mm, 20mm and 30mm in diameter respectively. Obtained results are as follow; (a) In view of the water catchment capacity, manufacturing cost and the antipressure strength of the catchment conduits, it is the best method to decide the total number of influx holes 20 per sq. meter of each tile surface, and the size of influx holes 20mm in diameter, when the conduits have diameter less than 1m. (b) The greatest factor of safety against external load is to arrange the influx holes in a zigzag manner on the tile surface. The most effective formula of arrangement is $S{\geqq}\sqrt{2gd}$ where: s : spacing of opening row. g : spacing of opening line. d : diameter of influs hole.

In terms of cultural history, museum architecture represents culture of society in an era. exhibition space which represents the society and culture can't be fixed in the same way in a current mobile era. Especially, mobility of exhibition can be able to give audience even opportunities to enjoy. As a result, mobile exhibition space that functions as total space for everybody and the study of this issue is necessary. As mobile exhibition space is in the middle of development, there are many things to make up for the weak points. In order to make mobile exhibition space more competitive, development of new form and material is needed most. besides, limited development on interior plans which has been overlooked in terms of mobility is needed. Also, there should be more aggressive and powerful marketing and promotion for mobile exhibition space. To equalize the metropolitan area and local exhibition space and revitalize domestic exhibition space, the utility of mobile exhibition space which is movable and economic is highly expected more than previous fixed exhibition space.

폴리카보네이트 (PC)와 몬모릴로나이트 (montmorillonite, MMT)의 나노복합체를 용액 및 용융 혼합 방법으로 층간삽입시켜 제조하여 X-ray 실험으로 MMT의 층간간격 변화를 조사하였다. MMT로는 $Na^+$를 양이온으로 갖는 순수 MMT (MMT-Na)와 도데실암모늄 (MMT-DA) 및 dimethyl hydrogenated tallow 2-ethylhexyl ammonium으로 개질된 MMT (MMT-25A)를 사용하였다. PC/MMT-25A와 PC/MMT-DA가 PC/MMT-Na보다 층간거리의 증가폭이 컸으며, 혼합방법에 따라 최대 $37AA$까지 층간간격이 증가하였다. 또 PC의 분자량이 작을수록, 혼합시간이 증가할수록 삽입이 잘 일어났다. 열중량분석법 (TGA)으로 측정한 열안정성은 PC/MMT-25A가 PC/MMT-Na와 순수한 PC보다 우수함을 나타내었다.

Intelligent video surveillance systems have been developed to monitor global areas and find specific target objects using a large-scale database. However, person re-identification presents some challenges, such as pose change and occlusions. To solve the problems, this paper presents an improved person re-identification method using sparse representation and saliency-based dictionary construction. The proposed method consists of three parts: i) feature description based on salient colors and textures for dictionary elements, ii) orthogonal atom selection using cosine similarity to deal with pose and viewpoint change, and iii) measurement of reconstruction error to rank the gallery corresponding a probe object. The proposed method provides good performance, since robust descriptors used as a dictionary atom are generated by weighting some salient features, and dictionary atoms are selected by reducing excessive redundancy causing low accuracy. Therefore, the proposed method can be applied in a large scale-database surveillance system to search for a specific object.

Face recognition (FR) with a single sample per person (SSPP) is common in real-world face recognition applications. In this scenario, it is hard to predict intra-class variations of query samples by gallery samples due to the lack of sufficient training samples. Inspired by the fact that similar faces have similar intra-class variations, we propose a virtual sample generating algorithm called k nearest neighbors based virtual sample generating (kNNVSG) to enrich intra-class variation information for training samples. Furthermore, in order to use the intra-class variation information of the virtual samples generated by kNNVSG algorithm, we propose image set based multimanifold discriminant learning (ISMMDL) algorithm. For ISMMDL algorithm, it learns a projection matrix for each manifold modeled by the local patches of the images of each class, which aims to minimize the margins of intra-manifold and maximize the margins of inter-manifold simultaneously in low-dimensional feature space. Finally, by comprehensively using kNNVSG and ISMMDL algorithms, we propose k nearest neighbor virtual image set based multimanifold discriminant learning (kNNMMDL) approach for single sample face recognition (SSFR) tasks. Experimental results on AR, Multi-PIE and LFW face datasets demonstrate that our approach has promising abilities for SSFR with expression, illumination and disguise variations.
