Purpose: As emergency medical service fund is further expanded due to amendment of the law on emergency medical services in 2008, Korean government has prepared to intervene in a comprehensive manner to strengthen a trauma treatment system. As a result, it announced a master plan to establish a serious trauma treatment center in 16 areas across the nation. Therefore, this study has attempted to investigate the current status of the serious trauma treatment centers and suggest the goal and improvement plan of future serious trauma treatment centers. Methods: As of 2011, Korea operates 23 emergency cerebrovascular service centers, 23 emergency heart disease centers and 35 severe trauma treatment centers across the country. 12 emergency medical service centers have been chosen among the serious trauma treatment centers. Then, top six (6) centers chosen at Emergency Medical Institute Assessment 2011 by Ministry of Health and Welfare have been selected, and floor layout and spatial allocation by usage have been reviewed and analyzed. Results: Consequently, this study has investigated the spatial components, circulation layout and spatial allocation of a serious trauma treatment. For construction planning in consideration of the fundamental objectives and goal of emergency medical services, it is essential to allot spaces and select exact spatial components. It appears that it is necessary to design spaces for emergency medical services and come up with construction planning through appropriate spatial allocation.

The rapid development of internet information technology has increased interest in e-Trade these days, but it is not activated greatly up to now. In order to promote e-Trade, it is essential to construct cooperative process such as connecting systems among trade related parties. Building e-Trade platform which is based on the infrastructure of the past trade automatic system is key point of promoting e-Trade. To do this, a study on the basic concept and specific components of e-Trade platform is needed absolutely. At this point of view, after this paper has examined domestic and foreign studies on the fundamental technologies about electronic commerce, it drew several key technologies that could be applied to e-Trade considering the current IT trend. Then it evaluates these technologies according to Technology Reference Model(TRM) of the National Computerization Agency. This will help us to show the operation strategy as well as the concept of future e-Trade platform and its composition. On the basis of the theoretical background, this paper classified NCA's technology model into 6 fields, which are application. data, platform, communication, security and management. Considering the key technologies, e-Trade platform has to be mutually connected and accept international standards such as XML. In the aspect of business side, trade relative agencies' business process as well as trading company's process has to be considered. Therefore, e-Trade platform can be classified into 3 parts which are service, infrastructure and connection. Infrastructure part is compared of circulating and managing system of electronic document, interface and service framework. Connecting service (application service) and additional service (application service) consist of service part. Connecting part is a linking mutual parts and can be divided into B2B service and B20 service. The organization operating this e-trade platform must have few responsibilities and requirements. It needs to positively accept existing infrastructure of trade automatic system and improving the system to complete e-trade platform. It also have to continuously develop new services and possess ability to operate the system for providing proper services to demanders. As a result, private sector that can play a role as TTP(Third Trust Party) is adequate for operating the system. In this case, revising law is necessary to support the responsibility and requirement of private sector.

After the development of printing technology since the 15th century and the rise of citizen consciousness in the 18th century, the library has taken a public concept. And after the 20th century, its role as a public library for the public was stressed, and as its spatial composition became miniaturized and specialized, its function changed from stacking and reading to various kinds including culture and service and is getting more complex beside the function of a library. Thereupon, this study aims to figure out the limitations of public libraries' opening years shown in advanced researches and understand the current status of spatial composition by complexation with the subjects of five public libraries opened after the end of December, 2006 in order to examine their tendencies of complexation and the characteristics of spatial composition by the complexation of public libraries. As a result, the present public libraries have at leaser more than two spaces with complex functions. According to the result of analysis on the types, locational relations between spaces showed the mixed type the most. In the types of building allocation, the building integrated type had a higher percentage than the separated type. About the types of entrance, the one common door type was fewer than the two separate door type. In the analysis on the types of the interior line of flow, the common type was similar to the dispersed type, and it is thought to be resulted from spatial composition rather than the preplanned line of flow.

For a period of over 6 years, more than 160,000 milk samples were collected and analyzed to determine the influence of different seasonal temperatures and geographic regional location on milk composition in South Korea. Fat, protein, lactose, non fat milk solids (NFMS) and total solids (TS) contents were significantly higher among dairy cows milked in winter season than other seasons (p<0.05). In contrast, freezing point (FP), milk urea nitrogen (MUN) and somatic cell count (SCC) were significantly higher in summer season than other seasons (p<0.05). The average SCC in the autumn season was $358{\times}10^3$/ml, which was lower than any other seasons (p<0.05). These results may be due to the changes in temperature during different seasons. Meanwhile, milk produced by dairy cows in central region had higher fat, protein, lactose, NFMS, TS and MUN and had lower SCC compared to other regions (p<0.05). Fat, TS, FP, MUN and citric acid in northeast region were lower than other regions (p<0.05). The SCC was significantly higher in southeast region than those of other regions (p<0.05). As a result, it might be possible that the differences in feeding management in each different region may affect the milk composition. In conclusion, present results indicated that milk composition is clearly influenced by both season and regional location. Therefore, based on these results, development of different feeding systems, according to season and region is needed to produce high quality and satiable milk production.

This study examined the age-related patterns in body composition cross-sectionally using Segmental bioelectrical impedance analysis(SBIA), specifically its two components, lean body mass(LBM) and body fat mass, in 1,452 men and 1,436 women with an age range of 19 to over 70 years . Mean height of male subjects was 174.1cm at peak in early 20's and was decreased continuously 0.2-0.3 cm every year. Mean weight was greatest between late 20's and 40's, and was decreased quickly in 70's. Body fat mass was increased steadily before 30's and remained thereafter. Because decreasing lean body mass (LBM), percentage of body fat(PBF) increased continuously with aging. Mean height of female subjects was 161.7 cm at peak in 20's and was decreased steadily around 0.2 cm every year and thus an individual's height was decreased approximately 10 cm in their life cycle. Body weight was increased steadily until 50's and then was decreased. Body fat mass was increased continuously and LBM remained constant and thus PBF was increased steadily with aging. SBIA can be used to compare body composition between genders and between ages. In future studies, SBIA could be applied widely to evaluate variations of body composition in subjects with different nutritional problems.

Turkish towel (Chondracanthus exasperatus), Pacific dulse (Palmaria mollis, also known as Red ribbon seaweed), and sea lettuce (Ulva spp.) were cultivated in a land-based intensive culture system at the Manchester Research Station, USA from August 2013 to September 2014. Macroalgae were grown in tumble-aerated tanks, harvested bimonthly for seasonal growth calculations, and analyzed for protein, lipid, ash, and amino acid content. Growth rate of all three species exhibited a similar pattern, with the highest specific growth rates occurring during the summer months (Turkish towel: 7.8%, Pacific dulse: 8.2%, and sea lettuce: 6.2%). Growth of all three species was lowest around winter solstice; with negative growth only observed in sea lettuce. On a dry weight basis significant differences in protein content existed between the three species with highest values for sea lettuce ($29.5{\pm}1.4%$). Lipid content varied between species (0.95-2.78%) with significantly higher lipid observed in sea lettuce (0.58-4.82%). No significant differences were detected on a seasonal basis among each species. Essential amino acids accounted for $43{\pm}0.9$ to $47{\pm}1.2%$ of total amino acids with Turkish towel having the highest value. Turkish towel had a significantly higher taurine level ($0.82{\pm}0.27$) than the other macroalgae. The levels of persistent organic pollutants and heavy metals were low. The estimated annual product of the three species ranged from 50- to $70-mt\;dry\;weight\;ha^{-1}\;y^{-1}$, significantly higher than conventional crops. Land-based culture of these species can produce year-round harvest, consistent product quality, and low contaminant levels.

Components extracted from 7 species and 18 populations of Chrysosplenium in Korea were compared and analyzed using GC-MS analysis. 57 components (${\geq}80%$ quality) were identified, of which neophytadiene, palmitic acid and phytol were found at all the taxa. Percentage composition of isolated extracts showed a clear difference in components type and GC-MS profile. On the basis of that result, data matrix was made and cluster analysis using UPGMA was conducted. From the result of cluster analysis, two groups were recombined; one with alternate leaves comprised C. japonicum in Ser. Alternifolia and C. flagelliferum in Ser. Flagellifera and the other with opposite leaves gradationally comprised C. psuedofauriei in Ser. Sinica, C. ramosum in Ser. Oppositifolia and C. sphaerospermum, C. valdepilosum, C. flaviflorum in Ser. Pilosa. These chemotaxonomic results agreed in general with those of existing studies on external morphology and molecular. In conclusion, chemical composition can be an useful characters in understanding the relation analysis among interspecific and intraspecific complex with the help of cluster analysis of 7 species and 18 populations of Chrysosplenium in Korea.

The aim of this study to present useful information on effective space composition by understanding education process of a preschool for children's education and required interior space for this process. The 6th education process of a preschool as the criteria on this study would be classified into 5 spheres as follows : Health life, Social life, Expression life, Language life. survey life. And the required interior space would largely be classified into interesting sphere and home sphere. As a result of analyzing the space composition, we can draw conclusion as follows : First, the interior spaces for properly doing children's education process have close relations. So, each sphere too independent or too unified is not good. That is to say, each sphere has closely organic connection for enhancing efficiency. Secondly, children's service spaces are considered to in children's education process. And the space had better be made for children only considering their physical states. Finally, we have to in advance process. And the space had better be made for children only considering their physical states. Finally, we have to in advance understand educational aim and program because space composition can be changed according to the aim of education process.
