International Convention Center Jeju(ICCJ) was planed and built for accommodating a variety of conventional and exhibitional activities. For a better flexibility of operation, almost all rooms in ICCJ are designed to be subdivided Into a couple of small rooms with installation of movable partition walls. Architectural and acoustical design should be deliberatively and cooperatively undertaken to cope with such a complex condition. Conference hall, the largest room in ICCJ, has a capacity of 5000 seats who:1 used as a whole. It could be divided into 3 halls, one with 2000 pre-installed seats on slanted floor, up/down removable stage and its settings above, and the other 2 flat rooms with no seats installed. A devided hall with pre-installed seats and stage is designed for a multi-use auditorium. Almost all surfaces except ceilings adjacent to the stage are sound absorptively treated, in regard to extensive use of sound reinforcement systems. Its reverberation time 1.65 sec without audience, which is roughly correspond to 1.50 sec with fully occupied audience. When there is a need for a larger room, all the partition wail Is removed and the hall could be used as a whole. Exhibition hall is located in the first floor of ICCJ. Absorption and softness are needed for the hat 1 because exhibition behavior has something noisy features. Perforated MDF panels with porous materials and air space in the back groundare adopted for the walls. There are one large, two medium, and several small convention rooms in ICJJ. The room are also acoustically designed for maximum flexibility with no defects soundwisely.

An enzyme ${\beta}$-galactosidase or ${\beta}$-galactohydrolase [EC3.2.1.23], commonly called lactase, mediates galacto-oligosaccharide (GOS) synthesis under conditions of high substrate concentrations. Also, lactase hydrolyzes ${\beta}$($1{\rightarrow}4$) lactose into glucose and galactose, the latter is successively transferred to free lactose to make various oligosaccharides via transgalactosylation. GOS is non-digestible to human digestive enzymes and has been used as a functional prebiotics. Among the 24 lactic acid bacteria (LAB) strains used, Lactobacillus paracasei YSM0308 was selected based on its exhibition of the highest ${\beta}$-galactoside hydrolysis activity, and the crude lactase was prepared for examination of reaction conditions to affect the GOS synthesis. Lactase activity was measured with a spectrophotometer using ONPG (o-nitropheyl ${\beta}$-D-galactopyranoside) method. Lactase activity was not detected in the culture supernatant and was mostly present in the cell pellet after centrifugation. Activity of the crude lactase preparation ranges from102 to 1,053 units/mL, with the highest activity determined for L. paracasei YSM0308. Optimal conditions for GOS synthesis are as follows: concentration of whey powder, pH, temperature, and time were 30%, pH 6.5-7.0, $30^{\circ}C$, and 4 h, respectively. The final GOS concentration was 19.41% (w/v) by the crude YSM0308 lactase, which was obtained from strain YSM0308 grown in the 10% (w/v) reconstituted whey-based medium.

As a medium for communication on science and technology, science museum could be important to adults who finished formal school education. By analysing all the exhibits at the National Science Museum and conducting a face-to-face interview survey toward 100 adult visitors, based on the PEP / IS model's perspective(Kim, 2007), this study aimed to find a way to induce many adults to visit science museum from the information consumer's viewpoint, not the information provider's one. The result was that most of the exhibits were not related to problems which people focused attention on. About half of visitors, therefore, did not relate their problems with exhibits and responded that there was no relationship between exhibits and their everyday life. However, they had an idea that science and technology could contribute to solving their problems. These findings could suggest that first, science exhibits in relation to people's focused problems or issues are to be developed, second, programs for parents who are accompanied by their children are to be developed, and last, adults' engagement in planning the science museum exhibits is to be considered.

In 2010 there are 759 public libraries in Korea, and they have been increased constantly for the recent four to five years. In order to make them as cultural spaces in local communities, Korean government is now planning to increase the number of public libraries up to 900 and to build small to medium-sized multiple purpose libraries rather than large and single purpose ones. Especially in the case of public libraries in metropolitan cities, which are main libraries in those areas, they should be designed to play major functions of cultural experience, exhibition, and life-long education as well as to meet the basic needs of providing books for public reading and of building and developing branch libraries based on local characteristics. Above all, in order to make a public library as a center of local culture, a space planning focused on increasing utilization and satisfaction of the residents is required. It is essential to conduct a survey to understand the needs of the residential users and reflect their opinions. In this regard, our research process was constructed as follows. First, precedent studies on a certain densely populated area were reviewed. Second, a survey was conducted in Ulsan city to figure out the needs and the satisfaction level of the actual users. The purpose of this study is to propose a better space planning approach for public libraries in metropolitan cities based on the analysis.

This study examined the effect of market sensing capability and information technology competency (IT competency) on innovation and competitive advantage in small and medium-sized tour operators (SMTOs). This research was conducted on the SMTOs located in three major cities for a tourism destination, meeting, and exhibition in East Java, Indonesia. 175 directors or managers of SMTOs were sampled using the purposive sampling technique. Data was obtained from directors or managers using a structured questionnaire. The empirical data was then analyzed by using Structural Equation Modeling (SEM). This study showed that market sensing capability positively and significantly affects innovation. Furthermore, competitive advantage was positively and significantly affected by market sensing capability. Although results showed that IT competence positively and significantly affects innovation, in contrast, it did not positively and significantly affect competitive advantage. These research findings suggest that market sensing capability and innovation have a substantial role in creating a competitive advantage for SMTOs facing the Revolution Industry 4.0 and a dynamic environment. Thus, innovation for SMTOs can be achieved by optimizing the role of market sensing capability and IT competency. However, this study also suggests that the capability or competence will not have any impact on competitive advantage if neither is optimized.

The Stele for National Preceptor Hongbeop from the Jeongtosa Temple site in Chungju is one of the most important stone cultural heritage items for exemplifying the style of the Goryeo era. Despite its obvious value, this relic has been stored in a weathered condition at the National Museum of Korea. It had suffered various dismantling and displacements during the Japanese colonial period and had long been exposed in the open air. The stele was selected as a subject for the Stone Monuments Restoration Project launched by the National Museum of Korea in 2015. In preparation for its outdoor exhibition as part of the restoration project, this study investigated the characteristics of its materials, produced a map of its deterioration from weathering, and carried out ultrasonic analysis of the materials to provide findings useful for conservation treatment. The materials analysis revealed that the turtle-shaped pedestal of the stele was made from two-mica granite consisting of medium-grained quartz, plagioclase, alkali feldspar, biotite, and muscovite. Its body stone is crystalline marble, the rock-forming mineral in which is medium-grained calcite in a rose-pink color with dark grey spots. The dragon top of the stele is made of crystalline marble, the major component of which is medium-grained calcite of a light-grey color. The deterioration consists of 21.5% abrasion on the stone body, with its south face most damaged, and 18.6% granular disintegration, with the north face most damaged. The ultrasonic material characterization conducted for mapping the general condition of weathering shows low values on the parts-assembly area of the turtle-shaped pedestal and on the upper portion of the stone body. It is considered that there is dislocation due to partial blistering and fracturing as well as to the differences in surface treatment. Prior to the outdoor exhibition of the stele, the surface was cleaned of contaminants and was consolidated based on the scientific investigation in order to prevent weathering from the external environment.

Conservation measures for excavated and surveyed buried cultural heritages are decided by the administrator of the Cultural Heritage Administration according to their scientific and historic values. However, management, preservation, and use after relocation and restoration remain unsystematic. An issue regarding preservation plan and use has arisen due to the damage of preserved heritages and protective facilities. Thus, this study aims to suggest a plan for preservation and use by investigating the present conditions of the preserved heritages in the Chungbuk area. Results showed that there are 43 preserved heritages in Chungbuk, most of which remain unmanaged systematically irrespective of the managing body. Remainder and protective facilities have been damaged due to wrong preservation treatments and selection of materials, and a problem also rises in terms of utilization, such as exhibition, education, and experience of preserved heritages. To improve such problems, a medium and long-term plan shall be established for the improvement of legal and institutional instruments, securing of budget, increase in professional manpower, development of standardization and inspection manuals, continuous monitoring, preventive preservation, research on relocation methods and materials, listing, and the creation of specialized museum and complex theme park. If a preservation plan suited to the investigated heritages can be developed, heritages can be preserved and managed more systematically and scientifically, and be used for various purposes like education, exhibition, public relations, etc.

As contemporary art tends to diverge from its fixed genres and intends to appeal to the public, fashion comes to contribute to the contemporary art area, by playing an important part in the creation of artistic value of art work. Nowadays, it is not unusual to see fashion work shown in an art exhibition parallel with art work, since some artists adopt costumes as the medium of their work in order to explore various means of expression. The occurrence of philosophical, sociological theories concerning human body parallelled with the prevalence of the post-structuralist ideas and occurrence of various styles of artistic expressions of body encouraged active research and attracted social attention to body. With such background, fashion art was formed by a means of the integration of body and fashion in order to create extreme artistic expression. 1 intend to investigate a variety of trends in fashion art from the viewpoint of body space. This study developed criteria for fashion image in contemporary art. Those criteria are based on the dichotomy that divides body into inner aspects and outer aspects. According to the criteria, Firstly, the extension type of body shape includes enlargement and reduction as its sub-types. Secondly, the opening-closure type includes opening type and closure type as its sub-types. Thirdly, the intensity type categorizes clothes into uniqueness and hybridity. Dynamism type classifies fashion art into fixation and moving. The various expressions of clothes type are interpreted as a means by which we can criticize many phenomena of modern society, such as loss of humanity, isolation of individuals, loss of identity, commercialism, and materialism. In the latter period of modern society, the integration of the double-faced nature of body and spirit was attempted and popular fashion was introduced into art in order to express desire, death, gender, identity, and sexual pleasure.

This paper delves into the recent 'paintings' of African-American artist David Hammons, which combine rubbish-like plastic wraps with the abstract-expressionist style paintings. In straddling between rubbish and art object, his works tend to blur the boundary drawn between two opposite categories in value, art and garbage, provoking the sophisticated taste of Upper-East-side white community in Manhattan, New York. Choosing the venue of his exhibition at a commercial gallery, Hammons's creative efforts is also a critique of what can be seen as the dominance of abstract expressionism and white elitism in American art history. The artist is known for his use of unconventional materials in art making such as black hair, barbecue bones, and elephant droppings, ones that are often associated with African-American experiences in all different levels. Since his debut in the art scene in the 1970s, Hammons has pursued the view of art-making as a medium for provoking contentious issues of racial relations in the States. On the other hand, the reception of Hammons's work as African-American art can be potentially quite limiting, overlooking as it does multi-faceted meanings of his art practice. His unconventional approach to art often took him outside art galleries and museums, where he was seen using a variety of common materials for site-specific installations and performances. Staged in different parts of Manhattan, these acts of art making traverse seemingly opposite communities and cultures, often blurring their boundaries. Hammons's artistic practice can label him what Abdul Jan Mohamed calls "specular border intellectual", revealing as it does the symbiosis of binary oppositions that is basic to the experience of communnal living.

The evaluation of art has been historically based on the thorough reliance on the subjectivity of beholders due to the fact that the production and appreciation of works of art is founded on the similar(subjective) value. There had been little attempt to reverse such tendency by creating an objective and quantitative checklist for evaluating a work of art. Centering on the evaluation of the Media Art, which increased dramatically in numbers since the late 1960s, this is an attempt in systematizing the quantitative evaluation of Media Art by reflecting the idea of subjective criticism as well as its medium specificity. As such, the criteria for the evaluation consist of media evaluation, work evaluation, appreciation evaluation, product evaluation and exhibition evaluation. The evaluators can be divided into the general public, the Media Art specialist and the curatorial staff, according to their experiences in dealing with the Media Art. Based on the result of the FGD, the weight has been added to the evaluation system according to each evaluation criteria to ensure the balance between the objective and subjective criticism.
