Purpose. To efficiently manage hospitals, this study aims to analyze the general characteristics, common-type balance sheet, common-type profit and loss statement and financial ratio of a tertiary general hospital and use the results as basic data for future hospital development by comprehending causes for problems and analyzing hospital management. Methods. By using information about a tertiary general hospital, located in A Metropolitan City, provided through Alio (www.alio.go.kr), a public organization information provider, Health Insurance Review & Assessment Service, and Ministry of Health and Welfare, this study used data during 3 years(2011 to 2013) by analyzing the general characteristics, common-type balance sheet, common-type profit and loss statement, industrial mean ratio and financial ratio of hospitals. Results. This study came to the following conclusions through the general characteristics, common-type balance sheet, common-type profit and loss statement, industrial mean ratio, financial ratio, circular chart and ROI by analyzing the data from 2011 to 2013. Conclusions. Overall, A Tertiary General Hospital showed an increase in fixed cost due to the construction of J Hospital and even in the size of capital and assets. It also showed an increase in medical profit, but the increase of its medical cost was higher, resulting in a financial loss. Especially, this hospital showed a slight decrease in net profit, featuring a reduction in inventory turnover. When the management of A Tertiary General Hospital was predicted based on such features, this hospital is expected to improve its profit structure through the opening of J Hospital, and it is necessary for this hospital to increase and sustain the turnover rate of inventories accumulated by managing them better.

Inventories, projections, and characteristics of spent nuclear fuel(SNF) generated from domestic nuclear power plants were updated to support high-level waste disposal system design. The historical and projected inventory by the end 2055 is expected to be 20,500 and 14,800MTU for PWR and CANDU spent nuclear fuel, respectively The ratio of quantity for TEX>$17{\times}17$ SNF was shown to be 0.6 as of 2003. The amount of TEX>$17{\times}17$ SNF, however, will be less than that of TEX>$16{\times}16$ KSFA after 2012, while the quantity of TEX>$16{\times}16$ KSFA will reach to 70% of the total spent fuels in the 2055. Average turnup of SNF revealed ~36GWD/MTU and ~40GWD/MTU for the period of 1994-1999 and 2000-2003, respectively. It is expected that the average burnup of SNF will exceed 45GWD/MTU at the end of 2000's. Therefore, it seems reasonable to use the TEX>$17{\times}17$ 4.5w/o, 45GWD/MTU as the Reference SNF at present state. The TEX>$16{\times}16$ KSFA 4.5w/o, 55GWD/MTU, however, should be Reference SNF after ~2010.

For each local town (6 cities and 8 counties) affiliated with Jeonbuk provincial government, characteristics of greenhouse gas (GHG) emissions were analyzed and key emission areas were drawn to establish mitigation policies of the regional greenhouse gases. National Institute of Environmental Research (NIER) reported that the total greenhouse gas emission of Jeonbuk was 20.93 million $tCO_2e$ in 2006. The inland area of 5 cities and 1 county (Jeonju, Gunsan, Iksan, Jungeup, Kimje, Wanju) covered 82% of total greenhouse gas emission in Jeonbuk, while the rest local towns of the province, mostly from mountainous areas were responsible for the rest of the total GHG emission. The cities and counties having relatively higher emission in Jeonbuk province were influenced dominantly by the emission from energy and waste sections. Also, agricultural section showed similar tendency except industrial cities such as Gunsan and Jeonju. In the internal portion of city and county, energy section showed the highest portion at the range of 72.1 (Sunchang)~97.0% (Jeonju) and agricultural section was at the range of 1.2% (Jeonju)~26.6 (Sunchang). When the portion of energy section was higher, the lower agricultural section. The emission index was applied to decide the key city and county and the potential city and county with two methodologies in this study. It was required that the key emission areas were drawn to establish regional greenhouse gases mitigation policies.

Biomass burning is known to be one of the main sectors emitting greenhouse gases as well as air pollutants. Unfortunately, the inventory of biomass burning sector has not been established well. We estimated greenhouse gas (GHG) and air pollution (AP) integrated emissions from biomass burning sector in Seoul during year 2010. The data of GHG and AP emissions from biomass burning, classified into open burning, residential fireplace and wood stove, meat cooking, fires, and cremation, were obtained from Statistics Korea and Seoul City. Estimation methodologies and emission factors were gathered from reports and published literatures. Estimated GHG and AP integrated emissions during year 2010 were $3,867tonCO_{2eq}$, and 2,320 tonAP, respectively. Major sources of GHG were forest fires ($1,533tonCO_{2eq}$) and waste open burning ($1,466tonCO_{2eq}$), while those of AP were meat cooking (1,240 tonAP) and fire incidence (907 tonAP). Total emissions by administrative district in Seoul, representing similar patterns in both GHG and AP, indicated that Seocho-gu and Gangseo-gu were the largest emitters whereas Jung-gu was the smallest emitter, ranged in $2{\sim}165tonCO_{2eq}$ and 0.1~8.31 tonAP. GHG emissions per $km^2$ showed different results from total emissions in that Gwanak-gu, Jungnang-gu, Gangdong-gu and Seodaemun-gu were the largest emitters, while Seocho-gu and Gangseo-gu were near-averaged emission districts, ranged in $0.2{\sim}21tonCO_{2eq}/km^2$. However, AP emissions per $km^2$ revealed relatively minor differences among districts, ranged in $2.3{\sim}6.1tonAP/km^2$.

In order to better quantify the contribution from nonroad sources to emission inventories, it is important to understand not only the emissions rates of these engines but also activity patterns that can be used to accurately portray their in-use operation. To date, however, very little information is available on the actual activity patterns of nonroad equipment. In this study, a total of 18 pieces of nonroad equipment were instrumented with collected data including intake manifold air pressure (MAP), exhaust temperature and, on a subset of vehicles, engine rpm and throttle position. The equipment included backhoes, compactors, dozers, motor graders, loaders and scrappers used in applications such as landfilling, street maintenance and general roadwork. The activity patterns varied considerably depending on the type of equipment and the application. Daily equipment operating time ranged from less than 30 minutes to more than 8 hours, with landfill equipment having the highest daily use. The number of engine starts per day ranged from 3-11 lover the fleet with an average of 5 starts per day. The average percent idle time for the fleet was approximately $25\%$ with a range from 11 to $65\%$ for individual pieces of equipment. Duty cycles based on exhaust temperature/throttle position profiles were also developed for two graders and one dozer.

The level of nitrous oxide ($N_2O$), a long-lived greenhouse gas, in atmosphere has increased mainly due to anthropogenic sources, especially application of nitrogen fertilizers. Quantifying $N_2O$ emission in the agricultural field is essential to develop National inventories of greenhouse gases (GHGs) emission. The objective of this study was to develop emission factor to estimate direct $N_2O$ emission from agricultural field by measuring $N_2O$ emissions in the red pepper cultivating field from 2010 to 2012. Emission factor of $N_2O$ calculated from accumulated $N_2O$ emission, nitrogen fertilization rate, and background $N_2O$ emission was $0.0086{\pm}0.00043kg$ $N_2O-N\;kg^{-1}$ N resulted from three year experiment of the research sites. More extensive studies need to be conducted to develop $N_2O$ emission factors for other upland crops in the various regions of Korea because $N_2O$ emission is influenced by many factors including climate characteristics, soil properties, and agricultural practices.

Purpose: The study was carried out to identify the correlations among social support, depression and life satisfaction, and compare them between the rural and urban elderly. Method: The study participants included 57 rural elderly and 59 urban elderly, who were surveyed and interviewed using social support and depression. like satisfaction inventories by nursing students from May, 2002 to June, 2002. Result: The mean scores of social support and life satisfaction in the urban elderly were higher than those in the rural elderly. However, significant differences in the variables between the two elderly groups were not found. The mean score of depression in the rural elderly was higher than that in the urban elderly, but a significant difference between the two groups in depression was not found. Social support was significantly correlates with age, religion, health status in the urban elderly and with family in the rural elderly. Depression was significantly correlated with religion, monthly expenditure, health status in the both groups. Life satisfaction was significantly correlated with age. marital status, religion, monthly expenditure in the urban elderly and with health status in the rural elderly. Social support, depression and life satisfaction were correlated each other in the urban elderly. The significant correlations were found between depression and life satisfaction, and between social support and life satisfaction in the rural elderly. Conclusion: The results suggest that further replicated studies are needed with larger samples. Appropriate nursing interventions with the consideration of characteristics of the rural and urban elderly are needed and developed to improve their social support and depression.

The purpose of this study was to investigate the effect of group music therapy for at-risk Korean soldiers on the levels of adjustment and stress. The study was conducted at a division of the Korean Army with 7 participants who were classified as "at-risk soldiers" based on the results of a psychiatric evaluation, MMPI-II and a personal interview with a counselor. The participants received 12 hours of group music therapy for three weeks and their scores on stress and adjustment inventories were compared before and after the treatment. The pre and post scores were analyzed with the Wilcoxon test for repeated measures. The results revealed that the overall stress level was significantly decreased while there was no significant improvement in the adjustment levels at p < .05. The research findings and personal remarks from the participants suggest that group music therapy may provide effective support for at-risk Korean soldiers in coping with stress and adjustment to military life.

For an efficient management and utilization of marine biodiversity information, we made an attempt to develop the Korea Marine Biodiversity Information System (KoMBIS), building a species name inventory of Korea marine organisms. The inventory includes 17 organism groups: phytoplankton, zooplankton, algae and halophyte, sponges, cnidarians, rotifers, nematodes, bryozoans, brachiopods, molluscs, echiurans, annelids, arthropods, echinoderms, urochordates and fish. The species names were collected from 37 different references and reviewed for validity by taxonomists, which resulted in 9,798 valid names in addition to 1,845 synonyms. The Korea marine species inventory is the first one of this kind, for previous Korean species name inventories were mostly composed of terrestrial and freshwater organisms. KoMBIS, the information system developed, contains not only the species name but also information on morphological and ecological characteristics such as distribution, DNA barcode, and references. This system is convenient for the inputting of new data and servicing users through the internet, so that management and utilization of the biodiversity information is more efficient. Linking the DNA barcode data with species information provides an objective measure for identification of a species, which accommodates the recommendation of Consortium for the Barcode of Life, and makes the Korea marine biodiversity information compatible with international databases. Considering the frequent exchange of marine organisms internationally via ballast water and such issues as climate change, this information system will be useful in many areas of marine biodiversity.
