This study was conducted to examine the present state, types of services, difficulties, education programs, motivation, satisfaction and attitude of hospice volunteers and also to suggest supporting programs for the volunteer. For these purposes, a questionnaire was distributed among the 200 hospice volunteers in ten hospice organizations in Daejeon and Chungcheong province. In this research, 85.5% of the respondents were women and most of them were housewives in their forties and fifties. The majority of hospice volunteers had an education background of more than high school. Christianity (94%) was the dominant religion of volunteers. Among the service area of the hospice, emotional caring, such as listening closely and establishing empathy were the most frequently done by the respondents and the next one was spiritual care. Hospice volunteers who had started with altruistic motivation show more dynamic activities in emotional, spiritual, physical caring and so on, than those with non-altruistic motivation. Most of the respondents expressed that they felt a hospice volunteer was valuable. However they had a hard time to overcome the sorrow coming from sharing empathy with the dying patients. Those who had started with altruistic motivation usually took part in two times per a week and had more positive attitude. Volunteers who had been working more than five years showed better attitude than those who had been working less than three years. The longer the voluntary services, the more positive attitude experienced by volunteers. Hospice volunteers encountered the most considerable difficulty with lack of background knowledge and their actual capability. Insufficiency of time was the next reason for the considerable difficulty of the hospice volunteer. On the other hand, those who served more than twice per week replied that lack of background knowledge and their capability were the least considerable difficulty. Insufficiency of time was the reason of difficulty for male volunteers, as well as for females under thirty and those in their forties and fifties respectively. Generally most of the hospice volunteers (70%) were satisfied with their services and they usually satisfied with physical caring, spiritual caring, hospice's family caring. The less difficulty in voluntary services, more satisfaction for the volunteers in the end. There is a positive correlation between a attitude of the hospice volunteer and frequency of voluntary services while the volunteers' difficulty affect negatively their attitude as well as the frequency of voluntary services. Most of the hospice volunteers want to have more education about basic skills, volunteer's attitude and role, spirituality, the way of attending on the hospice and so on. Most of them considered discussion and sharing different cases as the most effective method. They also wish to had more supporting programs for the hospice volunteers(in the order of their needs) such as regular events, newsletters, personal concern, social meetings among the volunteers, insurance and minimum expenses. Based on the study results, more programs should be run in order to activate the voluntary services regardless of their gender and education background. A continuous practical supporting policy and education programs are required in order to provide special education and training courses considering every field of voluntary services. Expanding the role of the volunteers allows them more opportunities to take part in voluntary services and th activate participation. It is necessary to establish a new hospice system as a part public medical system, which can not only facilitate the voluntary services for a hospice but also enhance professional hospice volunteers. Finally, experts are needed to operate the voluntary services effectively.

The habitat characteristics of Aconitum austrokoreense Koidz. were investigated to provide basic data for conservation and restoration. The altitude ranged from 260m to 728m with inclinations of $4-39^{\circ}$. As a result of vegetation survey within natural populations, a total of 147 taxa were identified inside 20 quadrates in 7 natural habitats. The importance value of Aconitum austrokoreense was 23.0% based on the coverage and frequency of the herbaceous layer and sat is more dominant. Species diversity was 1.23, and dominace and evenness were found to be 0.22 and 0.77, respectively. The soil type were silty loam (four sites), sandy loam (two sites) and loam (one site). The average field organic matter was 7.83% and the total nitrogen and pH were 0.35, and 5.69. Correlation analysis between environmental factors and population characteristic showed the correlations between chlorophyll content and slope, flowering rate and soil humidity. Conservation on habitats conditions is important for stable maintenance the flora and the surrounding area including habitats has to be designated a protection area for habitats conservation.
Italian ryegrass (IRG) is one of the fastest growing grasses available to farmers. It offers rapid establishment and starts growing early in the following spring and has fast regrowth after defoliation. So, IRG can be utilized as the dominant/single species of grass used in a farming system, or to play a role as a large producing pasture and sacrificial paddock. The objective of this study was to develop the use of unmanned aerial vehicle (UAV) for the evaluation of feed value of IRG. For this study, UAV imagery was taken on the Nonsan regions two times during the IRG growing season. We analyzed the relationships between $NDVI_{UAV}$ and feed value parameters such as fresh matter yield, dry matter yield, acid detergent fiber (ADF), neutral detergent fiber (NDF), total digestible nutrient (TDN) and crude protein at the season of harvest. Correlation analysis between $NDVI_{UAV}$ and feed value parameters of IRG revealed that $NDVI_{UAV}$ correlated well with crude protein (r = 0.745), and fresh matter yield (r = 0.655). According to the relationship, the variation of $NDVI_{UAV}$ was significant to interpret feed value parameters of IRG. Eight different regression models such as Linear, Logarithmic, Inverse, Quadratic, Cubic, Power, S, and Exponential model were used to estimate IRG feed value parameters. The S and exponential model provided more accurate results to predict fresh matter yield and crude protein than other models based on coefficient of determination, p- and F-value. The spatial distribution map of feed values in IRG plot was in strong agreement with the field measurements in terms of geographical variation and relative numerical values when $NDVI_{UAV}$ was applied to regression equation. These lead to the result that the characteristics of variations in feed value of IRG according to $NDVI_{UAV}$ were well reflected in the model.

Harmful dinoflagellate, Cochlodinium polykrikoides, has always occurred in southern coastal waters every year during summer, but it did not occur in 2009. A comparative study on outbreak in 2007/2008 and non-outbreak of C. polykrikoides in 2009 was performed based on environmental parameters and phytoplankton appearances. Samples were obtained at 13 stations from Yeosu to Wando waters in 2007-2009. The heavy rainfall was associated with the decrease of surface water temperature below $20^{\circ}C$ in July, the decrease of salinity below 31psu in August and increase of pH to 8.4 in Augus, 2009. concentration of DIN in 2009 was approximately too times as high as those of 2007 and 2008, and the ratioes of N:P and Si:N in 2009 showed Redfield ratio to be above the value of 16. This indicates that Redfield ratioes were significantly different between 2007/2008 and 2009. Dominant species during the field survey were shown to be Chaetoceros spp., Skeletonema costatum and Thalassiosir spp. in diatoms and to be Ceratium spp. in dinoflagellate. In partiuclar, Gonyaulax polygramma occurred in August, 2009 instead of C. polykrikoides. Consequently, the massive rainfall and shortage of sunshine contributed to considerable variation in environmental parameters which were associated with delay in the timing of rapid growth phase of C. polykrikoides.
The distribution and habitat characteristics of Echinosophora koreensis (Nakai) Nakai were investigated to compile basic data for conservation and restoration. The species Echinosophora koreensis is distributed within fourteen regions of the Korean Province of Gangwon, including Yanggu-gun, Inje-gun, Cheorwon-gun, Chuncheon-si and Hongcheon-gun. Natural habitats were located at altitudes of 192-626 m, with inclinations of $1-45^{\circ}$. One hundred and fifty seven vascular plant taxa were identified from 42 quadrats in 14 habitats. Dominant species among the woody plants, based on importance value, were Pinus densiflora and Quercus dentata in the tree (T1) layer, Quercus variabilis, Pinus densiflora and Quercus mongolica in subtree (T2) layer, and Fraxinus rhynchophylla, Prunus sargentii, Zanthoxylum schinifilium, and Ulmus davidiana var. japonica in the shrub (S) layer. Importance values for members of the herb layer were: Echinosophora koreensis 28.34%; Polygonatum odoratum var. pluriflorum 10.21%; Spodiopogon sibiricus 7.60%; Atractylodes ovata 4.77% and Carex lanceolata 4.13%. The importance values of the last four species were high, so they were at affinity with Echinosophora koreensis in their habitats. Average species diversity was 1.03, and evenness and dominance were found to be 0.82 and 0.16, respectively. The soil types were sandy loam and loam. Average field capacity was 13.28%, and the organic matter and soil pH were 6.70% and 5.77, respectively.
Soil nailing is the most general method to reinforce the slope by taking pullout and shear resistance force of the nail for stabilizing the slope. Domestic soil nailing design method considers only pullout resistance and does not consider the shear resistance sufficiently. In case of nail, the effect of tensile stress is dominant, but it is desirable to design by considering shear stress as well as tensile stress in case of slope where circle failures occur. Recently, studies on the shear resistance effect of nails have been carried out in the geotechnical field. However, many researches on the shear reinforcement effect of soil nailing have not been conducted until now. Most of the studies are about increasing pullout resistance by improving material, shape and construction method of nail. Therefore, it is necessary to the study on shear resistance of soil nailing and development of new methods to increase the shear force. In this study, large shear test and limit equilibrium analysis have been performed for a new soil nailing method to increase the shear resistance by forming protrusions through pressurized grouting after installing a packer on the outside of deformed bar. The study results showed that shear resistance of protrusion type soil nailing increased compared to soil nailing and it is more effective when applied to the ground with large strength parameters.

In this study we try to identify the three-dimensional mixing characteristics of Seomjin River discharges in Seomjin River Estuary and Gwangyang Bay using a seasonal field observation (CTD) during spring tide and a three-dimensional numerical model with EFDC (Environmental Fluid Dynamics Code). The tidal elevation conditions of the four main tidal harmonic constituents on the open boundary and river discharges and thermal effluents at the specific boundary are considered. The calculated harmonic constants of tide and tidal current agreed well with those of observations at two stations for tide and two stations for tidal current. The model successfully reproduced well known the estuarine circulation in Seomjin River Estuary where tide and river discharges are dominant forcings. In the winter mean discharges case, tidal currents move Seomjin River discharges in Seomjin River mouth and in the summer mean discharges case, river flows move Seomjin River discharges near ae Seomjin River Estuary. A three-dimensional mixing characteristics of Seomjin River Estuary show well a three-dimensional estuarine circulation and thermal effluents effect to the seasonal variation of river discharges.
It is required that gas accidents should be managed carefully as the consumption of fuel gas increases and high pressure gas process becomes more complex, which may cause a catastrophic accident. Factors to cause accidents were investigated through a systematic analysis of gas accidents between 1995 and 1998, which could be applied to prepare countermeasures to reduce gas accidents. As a result, it was suggested that the effective countermeasures to gas accidents should be kept applied, while new countermeasures were suggested in the field of increasing or not-decreasing number of accident. Totally 2,027 of accidents were reported during this term, and were found to decrease by about $12\%$ every year from 1996. The number of fuel gas such as LPG and city gas accident took up $96\%$, and most of accidents occurred at end-user's facility such as residential house and restaurant business. According to the kind of gas and facility, trend of accident by cause varies, while dominant causes are defective installation, appliance failure, or user's carelessness. Intentional accidents by fuel gas was excluded in this study because of its occurring mechanism and will be analyzed further elsewhere, although it took up $15\%$ and increased by $38\%$ every year.
BACKGROUND: Soybean [Glycine max (L.) Merrill] is a legume and an important oil crop worldwide. This study was conducted to evaluate the possible impact of transgenic soybean cultivation on the soil microbial community. METHODS AND RESULTS: Microorganisms were isolated from the rhizosphere soils. Microbial community was identified based on the culture-dependent and molecular biology methods. The total numbers of bacteria, fungi, and actinomycete in the rhizosphere soils cultivated with transgenic and non-transgenic soybeans were similar to each other, and there was no significant difference between transgenic and non-transgenic soybeans. Dominant bacterial phyla in the rhizosphere soils cultivated with transgenic or non-transgenic soybeans were Actinobacteria, Firmicutes, and Proteobacteria. The microbial communities in transgenic and non-transgenic soybean soils were characterized using the denaturing gradient gel electrophoresis (DGGE). The DGGE profiles showed the different patterns, but didn't show significant difference to each other at 0.05 significance level. DNAs were isolated from soils cultivating transgenic or non-transgenic soybeans and analyzed for persistence of transgenes in the soil by using PCR. PCR analysis revealed that there were no amplified ${\gamma}$-tmt and bar gene in soil DNA. CONCLUSION(S): The results of this study suggested that microbial community of soybean field were not significantly affected by cultivation of the transgenic soybeans.
The spreading Cocuoainim polykikoides bloom in the southern coastal waters of Korea was simulated using numerical model including the physical processes of water flow and the chemical processes of increasing cell of C. polykikoides by uptake of dissolved nutrients. The circulation of sea water was simulated by two dimensional tide model reflecting the main four tidal components of $M_2,\;S_2,\;K_1,\;O_1$, and permanent current was driven by inflow/outflow across open boundaries. According to the result of model which tidal and permanent current were reflected simultaneously, eastward flows entering the southern waters from the western waters of Korea are dominant but westward flows are weak relatively. These result suggest that it is difficult for initial C. polykikoides bloom generated in the coastal waters of Goheung to move to the western coast of Korea through Jeju Strait. For spreading model of C. poiyhikoides, the range of generating distribution and the generating time of C. polykikoides bloom in coastal area are similar to those of observation data in the field. Wind is the most important factor in moving and distribution of red tide. Permanent current flowing eastward is also considered to be important factor and tidal current was a little influenced.
