Considering heat insulation and beautiful sight of construction, making use of exterior panels is increasing. Recently the exterior panels now are weak very much, and so in consequence of the weakness fire spreads rapidly. Compared with internal fire, external vertical fire spread rate goes rapidly and it is extensive in spread range, therefore it is dangerous very much. Accordingly, under present condition of poor standard of exterior panels, it is required to take measure to meet the appropriate situation. In this study, by making use of FDS(Fire Dynamic Simulation) program about external vertical fire of high rise building, fire behavior is searched by computer. It is important that realizing by computer fire modeling about external vertical fire must be included certainly in procedure of fire performance design in the future. In modeling program, FDS version 5 is available, and aluminium composite panel is applied in external panels. In this study, for realizing of actual fire condition, FDS is applied by details of fire scenarios considering influence of wind.

Cosmetic mask is one of the traditional cosmetic product and is used to keep skin healthy and beautiful through moisturizing effect, cleansing effect and acceleration effect on microcirculation. There are several types of cosmetic mask such as peel-off type, tissue-off type, wash-off type and cotton sheet type immersed in cosmetic water. It is important for cosmetic formulators to develop an adequate type of cosmetic mask that meets the needs of the target consumers because each type of cosmetic mask has benefits and problems in its usage and efficacy. Polyvinyl alcohol (PVA) is widely used as an active ingredient of peel-off type cosmetic mask and the physical property of the PVA film changes with the usage of other ingredients. We studied the change of physical properties of the film containing PVA by formulating peel-off type cosmetic mask with the variation of humectants. Methylguceth-20 and glycereth-26 reduce the interaction between skin surface and PVA film without serious weakening of tensile strength and they can alleviate irritation. Glycerin, urea and betaine help PVA film soften and they also have excellent efficacy as humectants.

The First bentwood chairs in the world, called "winsor chairs" were made by British craftsman in the 17th century. Since then, from the start of NO.14 using solid bentwood by 19th-century German Michael Thonet, furniture making techniques such as Bent knee, Y-leg, X-leg- were developed based on Llaminated bentwood made by Alvar Aalto of Finland in the 20th century. In the 20th century Charles Eames of the United States studied Molded plywood, using plywood to produce a variety of furniture and during the 17~20 century a variety of Bentwood were developed. Coming into the 21st century, American Matthias Pliessnig and Phil Seaton worked with past Bentwood designs, developing Bentwood further by adapting Bentwood's know-how and IT technology. Science and technology evolved and Reholz of Germany developed technology which can mold three-dimensional wood using a new matarial called 3D-veneer, In the past only plastic or metal could be moulded 3 dimensional but now beautiful wood grain patterns can be molded by utilizing this technology. Also this is comparable with the past two-dimensional molding technology. In this Sustainable Design techniauses era, Bentwood fused with IT technology has great potential as a high-tech and eco-friendly techniche.

The most widely used material in furniture is wood. It is not only because it has good machinability and can be easily accessed, but also it is eco-friendly and human-friendly. Such material has been continuously being used for furniture and its machining method has been being actively researched and developed. Lumber has and has developed its own machining method. The conventional lumber machining method is difficult to make various types of furniture because it focuses on solving lumber's own modification problem due to the swelling and shrinking, and durability. Considering such characteristic of the material, a method to make it light and durable has been being researched and possibilities were found in wooden ships. Wooden ships are ships made of lumber, and are light and strong to be used in water. Also, in order to reduce the water resistance, it has streamlined curves so is formatively beautiful. The elegant curves and light and strong structure showed sufficient possibility to be used in furniture. Thus, the purpose of this study is to find a method to make various shapes of lumber lightly and strongly, using the production method of wooden ships, and to use this production method in designing furniture to propose a new form and structure of bench design, differentiating from conventional monotypic furniture.

This study analyzed the antibacterial activity of a Rubus coreanum (Bokbunja) ethanol extract. The antimicrobial activity was determined by disc diffusion, minimum inhibitory concentration (MIC), and growth inhibition methods with seven kinds of bacteria related to foodborne illness (Bacillus cereus, Escherichia coli, Escherichia coli O157:H7, Listeria monocytogenes, Pseudomonas aeruginosa, Staphylococcus aureus, and Salmonella typhimurium). In the results, disc diffusions of the ethanol extract from R. coreanum (9.8-17.5 mm at $4,000{\mu}g/disc$) clearly showed the antimicrobial activity of the extract against all tested microorganisms. Rubus coreanum promoted an inhibitory effect as follows: E. coli O157:H7 > P. aeruginosa > L. monocytogenes > E. coli > S. aureus > B. cereus ${\geq}$ S. typhimurium. In the MIC test, R. coreanum showed high antimicrobial effect against L. monocytogenes at 500 ppm. Moreover, the R. coreanum ethanol extract showed strong growth inhibition against microorganisms, similar to the MIC results. These results show that a R. coreanum ethanol extract has powerful antimicrobial activity against all tested microorganisms, suggesting that R. coreanum will be useful as a potential natural preservative.

This study examined the usage, perception and willingness to use beef traceability. The data were collected from 255 housewives in Busan and Gyeongnam region through a self-administered questionnaire. Frequency, Cronbach's ${\alpha}$, t test, one-way ANOVA, Duncan's multiple range test, Pearson's correlation analysis, and multiple regression analysis were conducted by SPSS Windows V.20.0. Only twelve percent of the respondents experienced to use beef traceability. Most respondents checked it by kiosk or bar code reader in a store. On the other hand, eighty-eight percent did not use beef traceability. The reasons for not usage of it were "Do not know beef traceability very well", "Do not know how to use beef traceability", and "Information from packing or counters is reliable" in order. In the level of perception of beef traceability, safety assurance was highest, followed by information quality, usefulness, and information accessibility. The percentage of correct answers of knowledge about beef traceability was not high. The multiple regression analysis showed that employment status, knowledge about beef traceability, information quality, information accessibility, and usefulness were significant factors to affect the willingness using beef traceability.
