The goal of this research was to identify problems associated with the management of nutrition support team (NST) in hospitals in Korea. Management status of NST in the hospitals was surveyed over the phone or interviewed by visit during August 2007. NST in foreign countries was collected by reference search and websites in the internet. Survey analysis also was performed during March, 2007 with forty-one medical staff in a university hospital located in Jinju, Kyungsangnamdo. Korean Society for Parenteral and Enteral Nutrition (KSPEN) was organized in 2001 and currently has thirty-three member hospitals with on-site NST as of August, 2007. Most of the member hospitals were big hospitals with more than 500 beds and were organized within five years. The most significant problem identified was the shortage of nutrition specialists exclusively involved in the NST. Survey analysis revealed that more than half of medical staff prescribed parenteral nutrition based on their own nutrition requirement calculation rather than consultation with NST. It appears that status of NST management of hospitals in Korea are considered to be at beginner stage and therefore, needs more aggressive advertising activity to increase consultation usage by medical staff.

This study is design to provide basic directions that Korea can take in forestry negotiation of Korea- Vietnam FTA. Trade trends and characteristics of forestry sector are figured out and the competitiveness of main products are analyzed. The trade amount between Korea and Vietnam is $207,260 thousand. Korea exports nontimber products to Vietnam, while she mainly imports wood products. The average import value of wood products during recent five years accounts for 88% of all value from Vietnam. The export items are not various, and the export value is small. The amount of imports, however, which are mainly composed of low price wood products, is relatively big. The results of analysis say that three items of Korean forest products have competitiveness, while Vietnam has eleven items. According to the study it is recommended that a sawn wood and a plywood should be classified as sensitive products to minimize and to take a long term tariff reduction.

In this paper, the characteristics of excessive horizontal stress components in Korea were studied using more than five hundred measured data set of in-situ hydraulic fracturing test. Based on the in-situ testing data, the magnitude and orientation of the horizontal stress component and variation of stress ratio (K) with depth were investigated. And also horizontal stress magnitude versus depth relationships and distribution limits of stress ratio components were suggested. For the depth less than 310 m in the entire territory, the stress ratio has a tendency to diminish and stabilize with depth, but fur some areas, it was revealed that the excessive horizontal stress fields with stress ratio close to 3.0 below 200 m in depth have formed. The results from the investigation of excessive horizontal stress regions showed that there existed several regions where the localized excessive horizontal stress was big enough to potentially induce brittle failure around the openings at less than 300 m in depth.

This study analyzed the lower body type of 30's Korean men to develop a slim-fit pants pattern. As the analysis data, direct measurement data of anthropometric measured value in the 6th Size Korea(KATS, 2010) was used as basic data with 481 men in 30's as analysis objects. The result are as follows. First, the result of analyzing factors for the lower body type classification indicated five factors. Second, the result of executing group analysis (with the independent variable of 5 clusters extracted from the factor analysis)classified the following three types. Type 1(36.8%) displayed a medium height of lower body type, small waist and hip, slim and fit body type with a slim shape between the knee and ankle. The shape between the waist and hip had characteristics of a slight curve and short length. Type 2(35.6%) displayed lowest height of a lower body type that was large and thick between the waist and the hip. The drop value of the waist and the hip was small; therefore, the body type was flat with a minimal curve. The underpart type (below the knee) was the thickest and the length was short. Type 3(27.7%) displayed the highest lower body type, a medium level waist size, flat and narrow waist and belly. This body type had a curve with big drop value of the waist and the hip, lower part from the hip to the ankle (including the knee) and a thick calf with along leg.

Recently, the population growth and agricultural development are rapidly undergoing in the South-West Texas. The junction of three river basins such as Lavaca river basin, Colorado-Lavaca Coastal basin and Lavaca-Guadalupe Coastal basin, are interesting for non-point and point source pollutant modeling: Especially, the 2 basins are an intensively agricultural region (Colorado-Lavaca Coastal/Lavaca-Guadalupe Coastal basins) and several cities are rapidly extended. In case of the Lavaca river basin, there are many range land. Several habitat types wide-spread over three relatively larger basins and five wastewater discharge regions are located in there. There are different hazardous substances which have been released. Total nutrient loads are composed of land surface load and river load as Non-point source and discharge from wastewater facilities as point source. In 3 basins region, where point and non-point sources of poll Jtion may be a big concern, because increasing fertilizers and pesticides use and population cause. This project objective seeks to how to assess and control the accumulation of non-point and point source and discuss the main impacts of agriculture and environmental concern as non-point source with water quality related to pesticides, fertilizer, and nutrients and as point source with wasterwater discharge from cities. The GIS technique has been developed to aid in the point and non-point source analysis of impacts to natural resource within watershed. This project shows the losses in $kg/km^2/year$ of BOD (Biological Oxygen Demand), TN (Total Nitrogen) and TP (Total Phosphorus) in the runoff from the surface of 3 basins. In the next paper, sediment contamination will show how to evaluate in Estuarine habitats of these downstream.

The amount and continuity of precipitation data used in a hydrological analysis may exert a big influence on the reliability of the analysis. It is a fundamental process to estimate the missing data caused by such as a breakdown of the rainfall recording machine or to expand a short period of rainfall data. In this study a linear programming method treated as a data-driven approach for estimating the missing rainfall data is compared with seven other methods widely used and its superiority is certified. The data used in this research are annual precipitation ones during 17 years at the Cheolwon station including an ungauged period of 15 years and its five surrounding stations. By use of this certified method the ungauged precipitation values at the Cheolweon station are estimated and the areal averages of annual precipitation data for 32 years at the Han River basin are calculated.

This study was carried out to grasp visiting nurses' perception of the service referral between health and welfare with a view to providing the basic data for the visiting nursing activities. A questionnaire survey was conducted on public health nurses in 25 health centers in Seoul from Feb. 12, 2001 to Mar. 15, 2001. A total of 151 questionnaires were collected and they were analysed by use of SPSS/WIN 7.5. The results of the survey are as follows. 1. In general, visiting nurses were burdened with heavy workloads. On average, a visiting nurse covered 5 ‘dong's(the smallest administrative unit), 564 households, and 1223 persons. They spent almost a quarter of their working hours moving from home to home and recording the charts after home visiting. They took 30-60 minutes to provide their services when visiting homes. As for the frequency of home visiting, they were following the instructions recommended by the government. However, their services were still wasteful, not skill-oriented, in that they spent more time assessing ‘subjects’ rather than providing their ‘services’ for them. 2. As for the degree of service performance, visiting nurses scored average 2.94 and 2.28 on the four-point scale in the area of health and welfare respectively. The Pearson coefficient between the two variables was high(.56). According as the health services increased, the welfare services increased as well, which showed that the service referral between the two areas should be essential. 3. ‘The necessity of cooperation with social welfare staff’ scored average 4.49, and ‘the degree of cooperation with social welfare staff’ scored average 3.16 on the five-point scale; There was a statistically significant difference (average 1.33) between the two variables. Such a big difference between perception and practice results from the lack of political support that connects the two service areas comprehensively. Therefore it is recommendable to establish a so-called ‘Visiting Nursing Center’ in the ‘dong’ office in order to provide integrated services of health and welfare at once in cooperation with social welfare staff. That's the way to meet the public needs directly and it's more efficient as well in terms of cost-saving.

The main objective of this research was to understand the latest trends of natural print design through the quantitative & qualitative analysis of fashion appeared in contemporary female collections. The research criteria was defined as 3 seasons from 2011 S/S to 2012 S/S. Data collection of 726 was done through review of 'pr$\hat{e}$t-$\grave{a}$-porter Collections' of three major fashion cities; Paris, Milan and NY. Statistical analysis of frequency with chi-square test was conducted. Also qualitative interpretation of natural print design' characteristics was completed. The main findings were as follows.; The average occurrence rate of natural print design from 2011SS to 2012 SS in three collections were 6.4% in Milan 6.4%, 5.5% in Paris and 6.8% in N.Y. The five source types of natural prints in contemporary women's fashion collections were identified and the order of their appearance were as follows: flowers, plants, animals, insects & marine organisms and compound one. The plant prints were expressed by stylized or realistic touch. Flower patterns showed more variables than plants, however, there were no big difference in their image and major characteristics. The animal prints demonstrated two aspects. First one used typical animal print of fur or skin, but the other one draw the animal figure like paintings. The compound source type presented the most interesting and fresh pattern design ideas. In the insects & marine organisms, mainly butterfly and seashell & starfish, etc. appeared as real shapes or sometimes were stylized.

Since energy efficiency has become a significant concern for network infrastructure, next-generation network devices are expected to have embedded advanced power management capabilities. However, how to effectively exploit the green capabilities is still a big challenge, especially given the high heterogeneity of devices and their internal architectures. In this paper, we introduce a hierarchical power management architecture (HPMA) which represents physical components whose power can be monitored and controlled at various levels of a device as entities. We use energy aware state (EAS) as the power management setting mode of each device entity. The power policy controller is capable of getting information on how many EASes of the entity are manageable inside a device, and setting a certain EAS configuration for the entity. We propose the optimal local control policy which aims to minimize the router power consumption while meeting the performance constraints. A first-order Markov chain is used to model the statistical features of the network traffic load. The dynamic EAS configuration problem is formulated as a Markov decision process and solved using a dynamic programming algorithm. In addition, we demonstrate a reference implementation of the HPMA and EAS concept in a NetFPGA frequency scaled router which has the ability of toggling among five operating frequency options and/or turning off unused Ethernet ports.

The amount of salt to make seed sorting solution of the specific gravity of 1.13 was reconsidered and determined as 3.8 kg salt in 18 L water, which is lower amount than currently used. Five rice cultivars were examined. Percent germination and seedling emergence were not similar. Seedling emergence rate of Japonica varieties, Nampyungbyeo and Daerypbyeo-1 were 87% and 95% under specific gravity of 1.13, respectively. Seedling emergence rate of Tongil type variety, Dasanbyeo was as high as 67% in specific gravity of 1.06. Seedling emergence rate of waxy rice, Hwasunchalbyeo and Aranghangchalbyeo were examined. Seedling emergence rate was 94% in both cultivars in specific gravity of 1.04. Seedling emergence rate was same in specific gravity of 1.08 which is generally used for selecting seed currently. Early growth (plant height, leaf number, and dry weight) were not significantly different by specific gravity within species. In all cultivars except waxy rice, highest seedling emergence rate was observed in specific gravity of 1.13 which is currently used for selection and decreased as specific gravity is lowed. However, considering total amount of seeds in each group of specific gravity, amount of seed in lower specific gravity group is relatively small and total seedling emergence rate within variety dose not show big difference. However, if seeds with low speicific gravity are produced due to the bad grain filling condition and consequently total seed content of low specific gravity increases, results will be differnt. Reduction in total growth and yield could occur. It will be important to comply with the seed sorting criterion of 1.13 for Japonica, 1.06 for Tongil, and 1.04 for waxy rice variety to ensure the maximum rice growth and yield.
