Social overhead capital (SOC) facilities are being threatened continuously by abnormal climate events that are increasing globally. For disaster response, rapid decision making on evacuation routes and other matters is critical. For this purpose, spatiotemporal information that combine data on disasters and SOC facilities needs to be utilized. This information is separately collected by government agencies and public organizations, and is not managed in an integrated manner. For rapid disaster response, an integrated management of separately collected disaster data and the creation of such information as the safety and damages on SOC facilities are required. To achieve this goal, it is essential to build inventories that integrate all the related information to support decision making indispensable for disaster response. In this study, a development plan for an integrated inventory management system based on the management and connection of inventories to support rapid decision making for disaster response is proposed. This system can collect and standardize data related to disasters and SOC facilities that are being managed separately and provide integrated information in line with the needs of users. The proposed system can be used as a decision making tool for proactive disaster response.

The large intestine of the chicken differs both anatomically and physiologically from the pig's large intestine and the men of the cow. The chicken's large intestine is less developed than the pig's large intestine or the cow's lumen. This paper summaries these differences. The chicken's large intestine contains a microbiological population similar to that found in the rumen. The chicken's caeca especially contains a large number of microorganisms, but this population varies according to age, fred, maturity, antibiotic use and etc.. Protein is an essential nutrient for the formation of intestinal microvilli. A study showed that the length of the small intestine was 63 % of the total gastrointestinal tract (GIT) length, while caecum was 8.1 %, and the colon and rectum were 4.6 %. The establishment of the microbial population of the small intestine occurs earlier than that of the caeca, but the identity of approximately 90 % of microbial population of the chicken GIT is hon. Recent studies have shown that energy, volatile fatty acid (VFA) and electrolytes that are found in the large intestine may be absorbed to a certain degree. The chicken small intestine is the primary location for digestion with a variety of enzymes being secreted here. Much research is being conducted into the digestion of sucrose thermal oligosaccharide caramel (STOP), fructooligosaccharides (FOS), mannanoligosaccharide (MOS), galactooligosaccharides (GOS) and isomalto-oligosaccharides (IMO) in the chicken caeca and large intestine. Excessive fibre content in the feed has detrimental effects, but proper fibre supplementation to chicken diets can improve the length and capacity of the small intestine.

This experiment was performed to investigate the effects of exogenous xylanase supplementation on performance, nutrient digestibility and the degradation of non-starch polysaccharides (NSP) in different sections of the gastrointestinal tract (GIT) of broilers fed wheat-based diets. A total of 120 7-day-old Arbor Acres broiler chicks were randomly allotted to two wheat-based experimental diets supplemented with 0 or 1.0 g/kg xylanase. Each treatment was composed of 6 replicates with 10 birds each. Diets were given to the birds from 7 to 21 days of age. The results showed that xylanase supplementation did not affect feed intake, but increased body weight gain of broiler at 21 day of age by 5.8% (p<0.05) and improved feed-to-gain ratio by 5.0% (p<0.05). Xylanase significantly increased (p<0.05) ileal digestibilities of crude protein (CP) by 3.5%, starch by 9.3%, soluble NSP by 43.9% and insoluble NSP by 42.2% relative to the control group, respectively. Also, compared with the control treatment, xylanase addition increased (p<0.05) total tract digestibilities of dry matter by 5.7%, CP by 4.1%, starch by 6.3%, soluble NSP by 50.8%, and had a tendency to increase (p = 0.093) insoluble NSP by 19.9%, respectively. The addition of xylanase increased the concentrations of arabinose and xylose in the digesta of gizzard, duodenum, jejunum, and ileum (p<0.05), and the order of their concentration was ileum>jejunum>duodenum>>gizzard> caecum. The supplementation of xylanse increased ileal isomaltriose concentration (p<0.05), but did not affect the concentrations of isomaltose, panose and 1-kestose in the digesta of all GIT sections. These results suggest that supplementation of xylanase to wheat-based diets cuts the arabinoxylan backbone into small fragments (mainly arabinose and xylose) in the ileum, jejunum and duodenum, and enhances digestibilites of nutrients by decreasing digesta viscosity. The release of arabinose and xylose in the small intestine may also be the important contributors to the growth-promoting effect of xylanase in broilers fed wheat-based diets.

This study examines the types and features of formal ritual hats for Tibetan Buddhist priests. Findings of the study are as follows. The types of formal hats that Tibetan Buddhist priests wear during religious rites or rituals include: u rgyan pad zhwa, pan zhwa, tshogs zhwa, rigs inga, zhwa nag, zhwa dmar and dwags zhwa. The reason why such formal ritual hats as listed above were developed is because the region had an alpine climate, and also because they were the symbolism of Buddhism, the most reverent priest, and reincarnated Buddha thoughts. They were an essential part of the culture of dressing Buddhist statues and offering utensils. Formal ritual hats' shapes originate from lotus. They are colored in red, yellow, indigo, green, white or black, that reflect the nationality and aesthetics of Tibetans. They are mainly made of woolen or silk fabrics. They are usually decorated with gold, git bronze or jewels and the patterns of the sun and the moon, vajra or clouds.

Noeui was a garment used for women's outfits and robes. In the late Joseon Dynasty it was a special garment that could only be worn by the class belonging to the royal family. Noeui was especially prepared as a wedding dress, and was worn by the bride at the Chinyeong ceremony on the day of the wedding ceremony. Until now, Noeui did not have in depth research at the costume history despite its importance as a royal costume in the Joseon Dynasty. Thus, based on Uigwe for the Royal Wedding Ceremony of King Injo and Queen Jangryeol (which is the only material with a diagram of Noeui and its pattern) this study historically investigated and restored the Noeui set of Queen Jangryeol, which was arranged in 1638, when King Injo and Queen Jangryeol were married. This academic study is the first to historically confirm and restore Queen Noeui's set, and rigorously analyze the historical materials as well as provide new comments on the shapes of Noeui's Git and the front side.

The purpose of this study is to introduce and research the traditional Korean costume collections of Dr. McCune who was born in Pyung-Yang in 1907 and resided until her marriage to George S. McCune in about 1930. Her collections consist of three categories : children's costumes, adults' costumes, access-ories. The characteristics of collections are summorized as follows : 1. Deep wrappings are found at the front part of the top clothing when worn. The front gusset (SUB) has been dramaticaly tilted due to the difference in lengths of the top and bottom parts of the front gusset. 2. Assymetry was one of the principles of decorating Korean costumes. The assymetry were repeated at the GIT and SUB of CHOGORE with patchwork patterns. 3. Primary colors were favored in Korean costume. Hue contrast in color combinations was prefered as well, such as : yellow CHOGORE and purple blue CUFFS, a red SUN pattern matched with green embroidery. 4. Surface patterns were not so popular in Korean costumes, while the most colorful and fabulous patterns were shown through the various embroidery artifacts. Patterns were used as a way of expressing of their desires or longings in Korean costumes. The main themes of the patterns were longevity and happiness. The patterns such as peony, lotus, chrysanthemum, bamboo and bat were implying symbolism at that time. 5. Natural materials were prefered for the garments, Silk and cotton were used as the main materials of the costume collections. Studies of Korean Costume collections owned by international collectors are meaningful to boost the arena of Korean Costumes as well as fill up the vacancy left by lost costume artifacts.

This research focus on the effect of developers' participation structure in knowledge creation and knowledge sharing activities in open source software development projects. Based on preferential selection theory, hypotheses of relationship between a developers' concentration of knowledge creation/sharing activities and collaboration performance was derived. To verify the hypotheses, we use the Gini coefficient in the commit contribution of the developers (knowledge creation) and the centralization index in the repository issue network (knowledge sharing network). Using social network analysis, this paper calculates centralization index from developers in the issue boards in each repository based on data from 837 repositories in GitHub, a leading open source software development platform. As a result, instead of all developers creating and sharing knowledge equally, only a few of developers creating and sharing knowledge intensively further improve the performance of the open collaboration. In other words, a few developers predominantly providing commit and actively responding to issues raised from other developers enhance the project performance. The results of this study are expected to be used by developers who manage open source software project as a governance strategy, which could improve the performance of open collaboration.

This study develops Korean Style Loungewear as a cultural fashion product. Through the use of surveys, Korean sentiments about Korean traditional clothing and Korean style fashion have been examined. The survey was conducted for 5,000 people in Korea; 3,500 responses of meaningful data were statistically analyzed. The data was processed by a SAS system; frequency and percentage were performed. It was found that Korean people have a high preference for Korean traditional clothing; however, they are not satisfied with its comfort, maintenance, or price. They answered that they would wear Korean style fashion if the design, comfort, and price were improved. They responded positively on the development of Korean Style Loungewear and its effectiveness as a cultural product. Based on the survey and basic geometric structures of Korean traditional costumes, silhouette designs of Loungewear have been developed. The designs are divided into one-piece styles and two-piece styles. The characteristic design details are git (Korean neckline) and goreum (Korean tie ribbon). The results have been shown on the "Han Style Fashion Show" by Jeonju City and exhibited in the "Seoul Living Design Fair" and the "International Art & Craft Trend Fair" in COEX, Seoul.

Inhibition of the growth of human cancer cells by proteins secreted from 373-L1 cells was investigated in the present study. The growth of human cancer cells was inhibited by co-culture with 373-L1 cells under 10% FBS and DME, DME, GIT and serumless medium, respectively. The conditioned medium of cultured 373-L1 cells under serumless medium was concentrated 100-fold through an ultrafiltration cell with a 10,000 molecular weight cutoff at 4$^{\circ}C$ under positive pressure using nitrogen(373-L1 EM). 373-L1 EM inhibited the growth of HeLa, Hep G 2, KHOS-Np, A43l and MCF-7 cells. 3T3-L1 EM was purified with FPLC, DEAE-ion exchange chromatography and phenyl-sepharose chromatography. The major protein of 373-L1 EM has a molecular weight of 66,000-68,000 in SDS-PAGE analysis. The results suggest that the inhibitory activity of 373-L1 EM appears to be due to some protein(m.w.66,000-68,000) secreted by 373-L1 cells.
