  • The C-terminal starch-binding domain of Bacillus cereus $\beta$-amylase expressed in Escherichia coli was purified and crystallized using the vapor diffusion method. The crystals obtained belong to a space group of $P3_2$ 21 with cell dimensions, a=b=60.20${\AA},\; c=64.92{\AA},\; and \; \gamma = 120^{\circ}$ The structure was determined by the molecular replacement method and refined at 1.95 ${\AA}$, with R-factors of 0.181. The final model of the starch-binding domain comprised 99 amino acid residues and 108 water molecules. The starch-binding domain had a secondary structure of two 4-stranded antiparallel p-sheets similar to domain E of cyclodextrin glucanotransferase and the C-terminal starch-binding domain of glucoamylase. A comparison of the structures of these starch-binding domains revealed that the separated starch-binding domain of Bacillus cereus $\beta-Amylase$had only one starch-binding site (site 1) in contrast to two sites (site 1 and site 2) reported in the domains of cyclodextrin glucanotransferase and glucoamylase.

  • This study was conducted to evaluate the combined effect of gamma irradiation and different conditions (vacuum packaging, antioxidant and freezing) on the microbiological and sensory characteristics of freeze dried Manila clam porridge (MCP) for immuno-compromised patient food. MCP can be sterilized at 1 kGy to 10 kGy. The initial counts of total aerobic bacteria and yeast molds in the non-irradiated MCP were $2.4{\pm}0.5$ and $1.2{\pm}0.3{\log}\;CFU\;g^{-1}$, respectively, but gamma irradiation significantly decreased the total aerobic bacteria to below the detection limit ($1{\log}\;CFU\;g^{-1}$) (5 kGy). Moreover, gamma irradiation effectively eliminated yeasts/molds at dose below than 1 kGy. However, gamma irradiation accelerated the increase of lipid oxidation and therefore, decreased the sensory characteristics of MCP as irradiation dose increased. To improve the sensory qualities of gamma irradiated MCP, combination treatment (vacuum packaging, 0.1% vitamin C) were applied. There was no significant difference in the overall acceptance scores between the combined-treatment sample (5.6 points) and the non-irradiated samples (6.0). The results indicate that combination treatment (vacuum packaging, 0.1% vitamin C) may help to maintain the quality of MCP. Therefore, it considered that irradiation of MCP with combined treatment and this is an effective method for the consumption as a special purpose food such as for space travel or immuno-compromised patients.

  • The main buildings of the important Buddhist temples - the pagoda, the Buddhist sanctum, the lecture hall - was surrounded by the cloister until Koryo Dynasty. And the Buddhist sanctum was located the center. It meant that the Buddhist sanctum was important building. It is very important thing that we understand the usage of the interior space because the architectural space consists of the unified space by the organic function of the interior space and the exterior space. But there is not so much the study on the interior space of the Buddhist sanctum. So, the purpose of this study is to understand of the interior space of the Buddhist sanctum in Ancient and Medieval Times. Till now, it was impossible that the Buddhist monk or the General public entered the Buddhist sanctum in Ancient and Medieval Times because they regarded the Buddhist sanctum as the place of sacrosanctity and the floor was finished by bricks. But, we saw that they could enter the Buddhist sanctum. Of course the floor of the Buddhist sanctum was finished by bricks, but they spread mats on the floor, took off his shoes in the interior space and used the furniture for sitting on. The plan of the Buddhist sanctum was designed by the process of the ceremony and the way of the enshrinement of the Buddhist statues because it is the place to enshrine the Buddhist statues. They performed the ceremony like as pray, worship, offer food to Buddha, HaengDo - an act to turn round an object of worship - and so on in the interior space of the Buddhist sanctum.

  • There are more and more citizens suffering from severe fatigue, and they wish to escape from it and spend their leisure time for healing. As a result, buildings and complexes are being constructed nationwide with healing as their theme. Particularly, they tend to build facilities with concepts like a spa, beauty, healing, meditation, nature, or forest healing. The purpose of this study is to examine the concept of healing environment and the nationwide tendencies of building facilities with healing as their theme and also investigate the planning characteristics of complexes and architecture with three representative complexes as examples. Complexes intended for healing have immersion into nature being freed from one's routine as their concept. When planning the flow of human traffic within the complexes, they try to obtain the autonomy of choice as well as the diversity of space and experiential factors in order to provide opportunities for experiencing nature. In the complexes selected for a case study here, they have planned the factors of physical environment that are associated with one another based on architectural education programs using red clay, programs specializing poetry, and healing programs using food. Typically, this is centered around outdoor experiential space, indoor meditation and education space, or fitness space. Also, it is characterized by the planning of physical environment and the complex operation of programs. Particularly, public space is divided into communal space, resting space, and health and treatment space, and health/resting space is mainly intended for health and exercise, for example, fitness, spas, or jjimjilbang (Korean dry saunas). Also, it is characterized by the planning of pitched roofs harmonized with nature and also facade planning that can positively adopt the factors of natural environment.

  • To enumerate Staphylococcus aureus in food, Baird-Parker Agar (BPA) is usually used in the conventional method, However it requires time and space for the preparation and plating, and incubation. Thus, use of the $3M^{TM}$ $Petrifilm^{TM}$ Staph Express Count Plate (STX Petrifilm) might be appropriate to solve these challenging problems. The purpose of this study was to compare the efficiency of STX Petrifilm with BPA for enumeration of S. aureus in various foods. A mixture of S. aureus strains ATCC29213, ATCC25923, and ATCC13565 was inoculated on marinated pork chop, beef (chuck tender), dried filefish, semi-dried squid, rice cake, and Japchae (stir-fried glass noodles) at 2, 3, 5, and 7 Log CFU/g. S. aureus cell counts were enumerated by spread-plating on STX Petrifilm and BPA after 0 and 24 hours at $4^{\circ}C$ (marinated pork chop, beef, semi-dried squid, and stir-fried glass noodles) and $25^{\circ}C$ (dried filefish and rice cake). Recovery of STX Petrifilm for S. aureus from various food samples was compared with BPA, and the results showed that there were no significant differences between two selective media in all cases. The results indicated that STX Petrifilm had enough efficiency to recover S. aureus from various foods as well as saving time and space.

  • Cultural analysis is closely related to 'Space' which we live in. This means that the shape of the space is not formed accidentally but is a cultural result from how we live. The approach through cultural analysis of space provides a good standard in order to understand, people's values and lifestyles. Today the purpose of sightseeing has changed from just visiting some famous places to experiencing unique culture of other countries. Especially the demand of the sightseers which makes you experience culture through tasting food has been increasing. Yet there are some Korean restaurants that don't show enough Korean culture accurately. The purpose of this study is to research the figural characteristics in Korean interior design with the method of cultural analysis and how they are expressed in the Korean restaurants. In addition, I'd like to suggest that Korean figural characteristics are not old fashioned but are modern things that have grate potential to be reinterpreted.

  • We live seeing, touching, or throwing on considerable textile in our life consciously and unconsciously. Since a Korean-style house is a dwelling space in life style of sitting on the floor with ondol(Korean floor heater), use of textile is limited to bedding goods. However, as western life style takes firm root, use of textile for interior design is increasing. As well, as apartments and foreign style houses have gotten lodgment since 1980, life style is being changed rapidly. So, textile became required factors in dining space where little textile existed. Through literature, history of textile is considered and design image concept is created based on the consideration. In addition, the created concept can be applied to various textile design, which can be a good tool to express eating culture of the country as well as the country's image.
