In this study, the shapes of po worn by military officers who served During the period of Japanese Invasion of Korea(1592-1598) were investigated. Findings of the study can be summarized as follows. Various types of po that military officers usually wore during the period of Japanese Invasion of Korea includes jikryeong, dapho, dopo, cheolik, aekjureum, jangeui, jungchimak and bangryeongpo. Out of these types, cheolik and jungchimak were most often used by the officers. Po that were usually worn by military officers during the period of Japanese Invasion of Korea as above mentioned is characterized as no difference in length between the front and back of the costume, kalgit and a pair of coat strings which are directly attached to po. The sleeves of the costume are bean chaff-shaped in some cases and just narrowly shaped in other cases. Similarly, the outer seop of po was either double-layered or single-layered. For jikryeong and dapho, mu is usually type of outside wrinkle. For dopo, its rear kit has the inner hem whose right and left edges are usually distant, respectively by 6~16cm, from the back center of the costume. Cheolik and aekjureum usually have either fine or broad pleats. For jangeui and jungchimak, mu is usually trapezoid in shape. Among various types of po which were usually worn by military officers during the period of Japanese Invasion of Korea, most representative are jikryeong from the tombs of Bae Cheon jo, dapho from Shin Yeo Gwan, dopo from general Bak and Bae Cheon Jo, cheolik from Nam Yoo and Cho Gyeong, aekjureum from Shin Yeo Gwan, jangeui from Kim Ham, jungchimak from Bae Cheon jo and bangryeongpo from Cho Gyeong.

This study aims to analyze the design of current nurse uniforms, investigate the state of nurse uniforms, and uniform design preferences in order to ultimately develop functional nurse uniform, which satisfy their needs. First, observing photos of nurses' campaign on wearing a badge showed that opening of top uniform almost always incorporated buttons, and sleeves were mostly set-in half sleeves while collars tended to be mandarin collars. The colors were mostly white for both top and bottom, while the top showed a bit more variety in colors. White tops often incorporated hospital logos on them. Second, in terms of the nurse uniform distribution, each nurse is given one top and one bottom per year. In addition, either a cardigan or a jacket on top of the regular summer uniform constitutes the winter uniform, whereas the availability of cardigans differed by hospitals. Third, the main source of contamination of uniforms was blood, and the level of satisfaction was all low in terms of the design, function, and material of the uniform, calling for the enhancement and development of new uniforms. Design preferences were two-piece with pants, color preferences were blue and pink, and pattern preferences were hospital logo, stripes, and check patterns in the listed order of preference. Complaints were usually made on the contamination of front pocket of the top, lack of sufficient pockets for storage, and tightness of the sleeves. Some preferences on finishing were the princess seams, mandarin collar, set-in half sleeves, and button closing on top. The preferred belt was a mixed form of straight-lined belt and rubber belt, and straight lined hem and spandex blended fabrics were favored for the clothing.

The purpose of this study is to examine the types and characteristics of decorative techniques applied to the Korean traditional skirt of contemporary style. For the purpose, this researcher selected 167 pieces of Korean traditional skirts which were shown in relevant monthly magazines published between 2001 and 2010. Then, the researcher classified the types of decorative techniques found in those selected pieces and analyzed the characteristics of decoration technique for each area of the pieces and the characteristics of patterns used in relation to those techniques. The Korean traditional skirt, otherwise called 'Hanbok chima', was classified into two types, single and composite, in accordance with which technique of decoration was used to it. The single type was characterized by so many embroideries, while the composite type, a combination of two decorative techniques, seonchigi and jatmulim. In the Korean traditional skirt, decorative techniques were applied to the knotting and entire of the skirt. Patterns used to decorate the Korean traditional skirt were usually in form of embroidery, gold or silver foil or painting. Out of the patterns, those which were embroidered or painted were shaped flowers, while those which were plated with gold or silver are shaped bosangdangchomun and flowers. There were other decorative techniques than mentioned above, for example, applying two or more different colors to the hem of the skirt, attaching pads to the knotting of the skirt and padding a decorative cloth on the front center of the skirt.

Adenosine and its analogues are known to possess analgesic effects and to be involved in the opiate-induced antinociception as well. This study was designed to investigate the effects of three adenosine agonists, 5'- (N-cyclopropyl) -carboxamidoadenosine(CPCA), 5'-N-ethylcarboxamidoadeno-sine (NECA) and $N^6-cyclohexyladenosine$ (CHA) on the signal transmission in the spinal cord and also to elucidate mechanisms of their actions in the anesthetized cat. All the tested adenosine agonists(i.v,) exerted inhibitory effects on the responsiveness of the wide dynamic range (WDR) cells, the inhibitory action of CHA, an adenosine $A_1$ receptor agonist, $(80{\mu}g/Kg)$ being most weak. The intravenous CPCA, an adenosine $A_2$ receptor agonist, $(20{\mu}g\;/Kg)$ and NECA, nonspecific adenosine receptor agonist, $(20{\mu}g\;/Kg)$ inhibited the responses of WDR cells to pinch and C fiber stimulation more strongly than those to brush and A fiber stimulation. CPCA (i.v.) also suppressed the responses of WDR cells to thermal stimulus. And all the CPCA-induced inhibitions were caffeine-reversible. When CPCA was directly applied onto the spinal cord or intravenously administered into the spinal cat, on average, about three quarters of the CPCA-induced inhibitory effect was abolished. On the other hand, in the animal with spinal lesions in the ipsilateral dorsolateral area, the CPCA-induced inhibition was comparable to that observed in the spinal cats. In conclusion, this study shows that adenosine agonists strongly suppress the responses of WDR cells to pinch, C fiber stimulation and thermal stimuli mainly through the supraspinal adenosine $A_2-receptors$.

Different bioligands carrying synthetic adsorbents have been reported in the literature for protein separation, We have developed a novel and new approach to obtain high protein ad-sorption capacity utilizing 2-methacrylamidohistidine(MAH) as a bioligand. MAH was synthe-sized by reacting methacrylocholride and histidine, Spherical beads with an average size of 150-200㎛ were obtained by the radical suspension polymerization of MAH and 2-hydrosyethyl-methacrylate(HEMA) conducted in an aqueous dispersion medium. p(HEMA-co-MAH) beads had a specific surface area of 17.6㎡/g . Synthesized MAH monomer was characterized by NMR. p(HEMA-co-MAH) beads were characterized by swelling test, FTIR and elemental analysis. Then Cu(II) ions were incorporated onto the beads and Cu(II) loading was found to be 0.96 mmol/g.These affinity beads with a swelling ration of 65% and containing, 1.6 mmol MAH/g were used in the adsorption/desorption of human serum albumin(HSA) from both aqueous solutions and hu-man serum. The adsorption of HSA onto p(HEM-co-MAH) was low(8.8 mg/g). Cu(II) chelation onto the beads significantly increased the HSA adsorption (56.3 mg/g). The maximum HSA ad-sorption ws observed at pH 8.0 Higher HSA adsorption was observed from human plasma(94.6 mgHSA/g) Adsorption of other serum proteins were obtained as 3.7 mg/g for fibrinogen and 8.5mg/g for γ-globulin. The total protein adsorption was determined as 107.1mg/g. Desorption of HSA was obtained using 0.1 M Tris/HCl buffer containing 0.5 M NaSCN, High desorption rations(up to 98% of the adsorbed HSA) were observed. It was possible to reuse Cu(II) chelated-p(HEMA-co-MAH) beads without significant decreases in the adsorption capacities.

Problems and improvemental measures for the historical inquiry of TV drama costumes and for the reproduction of them were investigated. For this study, the MBC historical drama 'The way of the Great King' started on march 24 in 1998 and ended on september 26 in 1998 was selected as the subject. The reasons why the drama was selected are as follows. First, the historical background was the time of King Young ＆ drama introduced various kinds of costumes Joungjo, which is the starting era of traditional costumes peculiar to Korea. Second, the based on the historical inquiry of that time. There is a limitation in the process of historical inquiry about the costumes of that time because we don't have enough research data such as relics, remains, references, literary works, pictures, etc. Although, in some cases, exact historical inquiry about the costumes were made, they could not be reproduced in the original forms due to several reasons: the absence of the materials of that time, structural changes including length and size for convenience of action, alterations of the manufacturing method for the reuse, addition of the gorgeous and various olors for the enhancement of image quality, variations in colors according to the actor's character, modulations of the structures and colors by the producer's intention, and the restraints in time and money for manufacturing. In view of these situations, it seems to be difficult for us to settle the problems occurring between the historical inquiry about the traditional costumes and the reproduction of them in drama. However, the costumes presented in historical drama have the meanings to provide informations of that time with TV audience. Therefore I think that it is necessary to narrow the gap between the historical inquiry of TV drama costumes and for the reproduction of hem, First, It should be restrained that each broadcasting stations show the costumes under the similar situations of the same age in different ways. Second, We need to unify the inquiry systems concerning historical drama costumes, In addition to this, it is also necessary for broadcasting stations to establish internet sites of traditional costumes for communication.

CVD-SiC coating has been introduced as a protective layer in TRISO nuclear fuel particle of high temperature gas cooled reactor (HTGR) due to its excellent mechanical stability at high temperature. In order to prevent the failure of the TRISO particles, it is important to evaluate the fracture strength of the SiC coating layer. It is needed to develop a new simple characterization technique to evaluate the mechanical properties of the coating layer as a pre-irradiation step. In present work, direct strength measurement method with the specimen of hem i-spherical shell configuration was suggested. The indentation experiment on a hemisphere shell with a plate indenter was conducted. The fracture strength of the coating layer is related with the critical load for radial cracking of the shell. The finite element analysis was used to drive the semi-empirical equation for the strength measurement. The SiC hemispherical shells were successfully recovered from the section-grinding of TRISO coated particle and successive heat treatment in air. The strength of CVD-SiC coating layer was evaluated from the experimentally measured critical load during the indentation on SiC hemisphere shell. Weibull diagram of fracture strength was also constructed. This study suggested a new strength equation and experimental method to measure the fracture strength of CVD-SiC coating of TRISO coated fuel particles.
