Given art gallery P with n vertices, the maximum (sufficient) number of mobile guards is${\lfloor}n/4{\rfloor}$ for simple polygon and${\lfloor}(3n+4)/16{\rfloor}$ for simple orthogonal polygon. However, there is no polynomial time algorithm for minimum number of mobile guards. This paper suggests polynomial time algorithm for the minimum number of mobile guards. Firstly, we obtain the visibility graph which is connected all edges if two vertices can be visible each other. Secondly, we select vertex u with ${\Delta}(G)$ and v with ${\Delta}(G)$ in $N_G(u)$ and delete visible edges from u,v and incident edges. Thirdly, we select $w_i$ in partial graphs and select edges that is the position of mobile guards. This algorithm applies various art galley problems with simple polygons and orthogonal polygons art gallery. As a results, the running time of proposed algorithm is linear time complexity and can be obtain the minimum number of mobile guards.

Several geophysical surveys(electrical resistivity, electromagnetic, seismic refraction, CPR) were conducted to primarily investigate the gallery and the geomembrane at an abandoned mine(Imcheon mine). The subsurface structure mapped from seismic refraction survey mainly consists of three velocity layers(>1000 m/s, 1000∼2000 m/s,＜2000 m/s). Top of the bedrock, whose velocities exceed 2000 m/s, appears to be at depth of 7.5∼10m. Higher resistivities (of ten thousands-hundred of thousands ohm-m) are interpreted to be associated with a open(cavities) gallery. The events at depth of approximately 0.5∼0.7m in GPR sections are probably caused by high-density-poly-ethylene geomembrane. Taking into consideration of the differences in the spatial resolution between georadar and electrical surveys, the events of geomembrane correspond to the top of the high resistivities at depth of about 2m. The segments, characterized with the higher conductivities in the electromagnetic data and the lower resistivities in the electrical resistivity data, are probably associated with surface water or tear zone of geomembrane.

The present study attempted the segmentation of the art gallery visitors on the basis of leisure lifestyles. For this purpose, leisure lifestyle surveys were administered at Korea's three representative art galleries, the National Museum of Modern and Contemporary Art, Seoul Museum of Art, and Seoul Art Center's Hangaram Art Museum. A total of 314 questionnaires were analyzed to identify leisure lifestyle factors. On the basis of the lifestyle factors, a cluster analysis was performed, and then the differences of demographics, museum visiting behaviors, and general cultural consumption among the clusters were examined. The cluster analysis revealed four groups of lifestyles, 'culture and art lovers', 'active homebodies', 'low leisure spenders', and 'omnivorous culture and sports participants'. The four groups revealed the differences in terms of demographics, museum visiting behaviors, and general cultural consumption. On the basis of the findings, the marketing strategies targeting the segmented art gallery markets were discussed.

The opportunity provided for design method and strategy of community space for secondary school through the experience of public library and gallery, is the purpose of this paper. Community space is an important issue in school architecture as it seeks to revive the public area in educational building and to renew the open space as a multi-entertainment space. The latest works of school, however, which are evaluated as well reflected the reality of educational patterns, are still deficient in that communicational elements in school are underdeveloped and inadequate. The cases of this paper, which are grown up as entertainment library and multi-purpose cultural space such as Seattle Public Library, Sendai Mediatech, Tate Modem Gallery, and Kunsthaus, are suitable to offer the method of the creation of community space for school. This paper reviews an assessment of its success in community space for school architecture with multi-entertainment-purpose library and cultural space connected open space and concludes with the establishment of design method for future school; extraction of the factors contributing to development of community space in school and proposal of design method; implementation of school renewal with library and gallery plus open space for the creation of identity considering both of study and play.

Recently major construction companies are building Housing Cultural Center instead of existing model house or housing gallery for accomplishing new marketing strategy. This Housing Cultural Center are different with existing model house or housing gallery on scale, spacial composition and operating program. And Background of differentiation is caused by change of housing market's environment, consumer's awareness level, service and marketing strategy. Because existing model house or housing gallery can not supply various consumer's needs and change of awareness level. Therefore, recent Housing Cultural Center is focused on cultural marketing for rapidly adjusting to new customer's need, including new customer acquisition and old customer retention. In accordance with this situation, it is very important to analyze out type and trend of Housing Cultural Center as facility for enlargement of cultural service and companies's social role for consumer. Therefore, the purpose of this study is an analysis about the trend of Housing Cultural Center as cultural space and a presentation of concept, function and direction when other construction companies build Housing Cultural Center hereafter.

The present study attempted to explore the impact of art gallery visitors' motivation and perceived quality of experience on satisfaction. For this purpose surveys were conducted at art galleries. The factor analyses identified four dimensions (knowledge, leisure, yearn for culture and art, and relationship) of motivations and another four dimensions (esthetic/entertainment, education, escapist, and sense of belonging) of perceived quality of experience. Subsequently, regression analyses revealed the influence of motivations and perceived quality of experience on satisfaction. Based on the findings, managerial implications and suggestions for further studies were discussed.

An azoinitiator linked to an epoxy oligomer, which could easily diffuse into the organoclay gallery and swell it, was used as an initiator to enhance the delamination of an organoclay, Cloisite 25A, in a matrix of styrenic polymers, poly(styrene-co-acrylonitrile) and polystyrene, during the preparation of a nanocomposite via an in-situ polymerization method. X-ray diffraction results and transmission electron microscopic observation of the morphology showed that the epoxy segment enhanced not only the delamination but also the extrication of ammonium cations from the organoclay gallery into the polymer matrix. The latter phenomenon induced the structural change of the alkyl group of ammonium cations in the gallery from a bilayer to monolayer structure, and also decreased the glass-rubber transition temperature as measured by a differential scanning calorimeter and dynamic mechanical analyzer.

Acquisition of the FIDO authentication technology in pursuit of improved security function of the NFC-based 2 factor electronic payment system enabled GenoTech Ch., Ltd. to develop its new service, Gallery-Auction, demoed at Daegu Exhibition. The demonstration was followed by the improvement requests in banner creation & installation, changes in UI, changes in order of operation, etc, which were taken into account for the succeeding update. During the second demonstration held at 'Art: Gwangju: 17,' it analyzed and visualized the number of visitors per hour there.
