The purpose of this study was to evaluate thermal properties of Taekwondo wears with three different materials. As a begging step, the questionnaire survey about the actual condition of Taekwondo wears was conducted. With the results of the questionnaire, cotton/nylon(70/30) blended fabric(CN) that was newly woven with sweat absorbent finishing and cotton/spandex(95/5) blended fabric with flexibility property were developed. The same designed 3 Taekwondo wears with 3 different materials which were two different materials(CN and CS) and a current material(cotton/PET, CP) were made. Four young males volunteered for this study, they kicked and punched as Taekwondo action for 20 minutes. Mean skin temperature was the highest in CS(33.1${\pm}$0.8$^{\circ}C$) and the lowest in CP(32.7${\pm}$0.6$^{\circ}C$). Increasing degree of rectal temperature didn't show any significant difference. Clothing microclimate temperature on the thigh was higher in CS(32.8${\pm}$17.4$^{\circ}C$) than in CN(29.4${\pm}$1.1$^{\circ}C$) and CP(29.4${\pm}$1.0$^{\circ}C$). Clothing microclimate temperature on the back and humidity on the thigh didn't show any significant differences. Clothing microclimate humidity on the back was higher in CP(65${\pm}$20%RH) than in CS(61${\pm}$17％RH). Heart rate, total body weight loss, and local sweating were not significantly different by materials. Most subject responded more hot in CN than in others, but there were no significant differences at the subjective sensation of thermal humidity. They answered more comfortable in CN than in others. Tectile sensations were the best in CN and the worst in CS. From those results, first of all, it is necessary to be weighted on Taekwondo wears made of CN in the aspects of the dignity of military arts uniform. Secondly, CS was required to be lighted and enhanced for the subjective sensation. Third, CP weaved honey comb was asked more various design to eliminate sweat high competition power within the scope of the dignity of military arts uniform.

The purpose of this study is to examine the characteristics of man's boots in the Joseon Dynasty and compared them with those of the Ming and Qing Dynasty to find the influential relationships between them. Boots in the Joseon Dynasty are divided into several kinds such as Heukgwejapihwa, Hheuksapihwa(黑斜皮靴), Heukpihwa(黑皮靴), Mokhwa(木靴), Hyeopgeumhwa(挾金靴), Suhwaja (水靴子), Jeonpihwa, Gijahwa(起子靴), and Baekhwa(白靴). In addition, Jeong(精: footwear) was put inside boots. They tend to be named according to their materials or ornaments on them. First, Jeong put inside the boots is regarded as footwear for the comfort of the feet or protection against cold. Mokhwa appears in literature around the 19th century. As shown by remains and paintings of those days, it is considered to have become the common name of boots as it underwent many changes. On the other hand, a book in the era of King Gojong includes pictures of Suhwaja. Compared to Hukpihwa in the same book. The topside seems to have been raised in order to make the wearer who put on a military uniform feel comfortable when walking, since the bottom piece is hard. Baekhwa is worn not only with funeral garments but also with Sibok(時服), one of official uniforms. Boots in the Joseon Dynasty had been made following the design of the Ming Dynasty since official uniforms were conferred upon King Gongmin in the late Koryo Dynasty. But turning the late Joseon Dynasty its detailed design changed little by little. The topside of the boots became more round, the entrance part became wider, height of the shoes became taller, and the bottom piece became parallel to the ground.

In South Korea, hospital clothes for medical staff, which require high performance and functionality, are still regarded just as uniforms. Few researches have been made into the underwear for operating room staff, which is intended to protect medical staff against possible risks happening during an operation and allow them to do their job in an easy and comfortable manner. In order to present a new design of underwear for operating room staff at general hospitals in South Korea, an investigation was made into medical staff's preference for overseas brand samples, and it was found that they preferred to wear such clothes as are blue-colored, of a V-neck line, of a box style and has good absorptiveness and breathability. After developing the primary prototype and the conventional underwear for operating room staff at Hospital A, their appearances were evaluated, and it was found that the primary prototype was more favorably evaluated. After developing the secondary prototype, their preference for the colors and shapes was surveyed, and it was found that they preferred to wear No.6 blue colors and T/C materials. In conclusion, it is considered that a systematic research need be conducted into the designs of various hospital clothes, whose roles and functions are subdivided, including the underwear for operating room staff developed in this research.

The change towards meeting diverse customer needs has started to affect the hotel industry as well. Design hotels emerged as customers demanded differentiated lodging experiences they could not fulfill at franchise hotels which were uniform in style everywhere in the world. Design hotels are meant to provide a new concept of space through unique design sensibility and work of designers, which highlighted the role of interior design. This research analyzes the characteristics of indoor space expressed in design hotel common spaces by the French designer Andree Putman, also known as the founder of boutique hotels and the concept of design hotels. As the original founder of the concept of design hotels, Putman's scope of work stretches wide, from interior design to product design. She is also one of the few French designers with a modernist inclination. The research runs a review on previous literature, characteristics of design hotels according to design tendency, and the association with characteristics of indoor space designed by Andree Putman, followed by case analyses extracted by analyses on design characteristics of common spaces she has designed. The analysis reveals that she creates comfortable yet elegant space, using contrast and fusion arising from negotiation of design styles to interpret space, the sense of spatial balance and understated expression of order through symmetrical structures, diverse creation of space through geometric structuring, highlighting indoor space by utilizing lights as objects, and the heterogeneous harmony achieved by contrasting juxtaposition, and understated formativeness. It is expected that study results would be utilized as methods of new designs of interior space in design hotels.

This paper sees some legal phases of the forfaiting transactions performed by using bills of exchange (drafts) or promissory notes. It focuses on the issues of the endorsement without recourse and the aval under the Korean statute for such negotiable instruments which is enacted by succeeding to the Convention Providing a Uniform Law For Bills of Exchange and Promissory Notes (Geneva, 1930) of the League of Nations. This paper purposes to give basic legal guides for forfaiting participants in order for them to be able to prevent and solve some problems caused by lack of understanding for relevant rules of law. Forfaiting is a useful technic as it provides financing for international export businesses by enabling forfaiters to discount future payment obligations on non-recourse basis. It gives benefits to exporters by removing political, transfer and commercial risks of importers or their country. Also it protects exporters from the risks of the increase of interest rates and the fluctuation of exchange rate as well. In traditionally normal forfaiting transactions, exporter of goods generally takes promissory notes or accepted drafts from importers in payment for the price of goods. Further, when the exporter is not comfortable with the importer's credit or is not confident whether the importer will pay the accepted drafts or the promissory notes as they come due, the exporter nomally requires the importer to make the importer's bank (avalizer or guarantor) add an aval, which is made by the written expression of intention, the words of "per aval", and the guarantor's signature on the drafts or promissory notes. The exporter endorses without recourse to transfer the drafts or the promissory notes to the forfaiter, typically a bank, who purchases the drafts or the promissory notes without recourse.

Qualitative enhancement of dwelling life has changing the recognition for the environment friendly wood which is being highlighted for its usage as an interior materials. This trend may prove the excellent performance of wood whose inherent characteristics has its comfortable, mild feeling of material, sound resistance and stabilities and the market of interior woods including floor, moulding and wooden panel as finishing interior materials is growing sustainably. However, since this materials is vulnerable to humidity and flame, waterproofing and flame retarding stability, an essential condition for interior materials, together with maintenance, are the main topics to be resolved. From the above-mentioned results, as a result of waterdrop contact angle, wood absorption volume and water content percentage test and the performance test of the processed materials after flame retardant, though there was some submerging time changes among types of woods for ensuring waterproofing performance improvement but as time passes, similar tendency was noticed to be formulated. As the submerging time is increased, so does the absorption volume and accordingly optimal level of range is judged to be drawn in order to ensure excellent performance, taking optimal economy into consideration. Therefore, it is considered that above-mentioned woods could be utilized for waterproof and flame retardant processed interior materials using uniform microwave and in order to put this technology into practical application, a research by way of diversified performance proving is required to be carried out.

For the prolonged delivery and sustained release rates of low molecular weight drugs, poly(lactic-co-glycolic acid) (PLGA) microparticles containing the drug SKL-2020 have been investigated. On increasing polyvinyl alcohol (PVA) concentration (from 0.2% to 5%), the size of microparticles decreased (from $48.02{\mu}m$ to $10.63{\mu}m$) and more uniform size distribution was noticeable due to the powerful emulsifying ability of PVA. A higher drug loading (from 5% to 20%) caused a larger concentration gradient between 2 phases at the polymer precipitation step; this resulted in decreased encapsulation efficiency (from 34.19% to 25.67%) and a greater initial burst (from 61.71% to 70.05%). SKL-2020-loaded PLGA microparticles prepared with different fabrication conditions exhibited unique release patterns of SKL-2020. High PVA concentration and high drug loading led to an initial burst effect by rapid drug diffusion through the polymer matrix. Since PLGA microparticles enabled the slow release of SKL-2020 over 1 week in vitro and in vivo, more convenient and comfortable treatment could be facilitated with less frequent administration. It is feasible to design a release profile by mixing microparticles that were prepared with different fabrication conditions. By this method, the initial burst could be repressed properly and drug release rate could decrease.
