This study was carried out ot investigate effects of X-537A on hydrogen ion concentration insperm washed solution and sperm acrosome reaction. The results obtained were as follows. 1. When bovine sperm was twice washed with SHP solutions of pH 6.8 and 7.4 and again washed with SHP solution containing 4$\mu$M of X-537A, in case of pH 6.8 the sperm washed with 4$\mu$M of X-537A showed signifciantly(p<0.01) higher hydrogen ion concentration in sperm washed solution than the sperm washed without X-537A. 2. When the sperm was twice washed with SHP solution and then washed with SHP solution containing 4$\mu$M of X-537A, sperm acrosome rection rate was signifciantly(p<0.01) increased from 12min after incubation in the sperm washed without X-537A, but was signifciantly(p<0.01) increased from 8 min after incubation in the sperm washed with 4$\mu$M of X-537A. 3. When the sperm was twice washed with SHP solution and then washed with SHP solution containing 0, 4 and 40$\mu$M of X-537A, and then incubated in m-TALP for 120 min, sperm acrosome reaction rate was significantly(p<0.01) increased from 15 min after incubation in 0, 4 and 40$\mu$m OF X-537A. However at 60 min incubation 40$\mu$M of X-537A showed significantly(p<0.01) higher sperm acrosome reaction rate than 0 and 4$\mu$M and at 120 min incubation 4 and 40$\mu$M of X-537A showed signifciantly(p<0.01) higher acrosome reaction rate than 0$\mu$M of X-537A.

We report the first case of summer-type hypersensitivity pneumonitis(SHP) in Korea diagnosed by positive serum antibodies to Trichosporon cutaneum. Hypersensitivity pneumonitis(HP) has been commonly classified as an occupational respiratory diseases. However, evidence that sensitizing organisms can also contaminate and cause pulmonary diseases in home environment has been increasing. One such disease is SHP. In Japan, 75% of cases with HP are SHP. Even though there has been no known SHP case in Korea yet, there has been high possibility of SHPs in Korea because our country has areas which have hot and humid summer climate similar to Japan. This first case of SHP in Korea suggests that there may be another cases in Korea and nation-wide survey may be required. We report here the first confirmed case of SHP in Korea.

The purpose of this one group pre and post test study was to evaluate the effect of self-help programs(SHP) which has been conducted from 1997 to 2000. The SHP was held by Korean Rheumatology Health Professionals Society(KRHP) once a week for 6 weeks for chronic arthritis patients in Korea. Eight hundred fifty five subjects completed the program at 43 sites. The effect of SHP were evaluated by flexibility, pain, activities of daily living(ADL), fatigue, depression and self-efficacy. After SHP, followings were found: 1. Participants' characteristics of SHP were most common in living in Seoul, women, sixties, high school graduates, house wifes, osteoarthritis, completed in 1999. 2. The flexibility of arm, knee, ankle joint were significantly increased, but the flexibility of the shoulder was not changed. 3. Level of pain was decreased significantly from 5.21 to 3.99, and the number of painful joints were decreased from 4.96 to 4.18 significantly. 4. The score of ADL was increased from 53.74 to 54.97 significantly. 5. The score of depression and self-efficacy was not changed. In conclusion, SHP was clearly proved to be an effective nursing intervention to Increase the flexibility of arm, knee, ankle joint and enhanced ADL. Also SHP decreased pain and fatigue. More research is needed to determine the role of self-efficacy and depression in the SHP, use of a randomized design and longer follow up period to understand more about the effects of the program.

This study addresses the development of a soy hamburger patty containing enzyme-treated textured soy protein (TSP) as a meat analogue. In order to reduce the beany flavor and enhance the texture, TSP was treated with 0.3% Flavourzyme for 5, 10, 20, or 30 min. The degree of hydrolysis and the water holding capacity of the TSP increased with increasing hydrolysis time. The oil binding capacity of the TSP also increased with increasing hydrolysis time, approaching the maximal value, 175.82%, at 30 min, whereas that of pork scored with the lowest value of 128.67%. The volume of pork was reduced to 81.5% as the result of heat treatment, whereas that of the TSP increased to 140.57%. The values of 'L', 'b', and '${\Delta}E$' differed significantly (p<0.001) with heat treatment, but the 'a' values did not differ significantly. With regard to texture, the hardness values were highest in the pork hamburger patty (PHP), and were lowest in the soy hamburger patty (SHP) containing untreated TSP. The hardness of the SHP containing TSP treated for 20 min did not differ significantly from that of the PHP. The cohesiveness and gumminess of the SHP treated for 20 min were highest, whereas those treated for 10 min were the lowest. The gumminess of the SHP treated for 20 min did not differ significantly from that of pork. The chewiness of the PHP was the highest, whereas that of the SHP treated for 5 min was the lowest. In our sensory evaluation, PHP evidenced the highest scores, followed by the SHP treated for 30 min, as color, texture, beany flavor, and overall quality all improved as the consequence of increasing enzyme treatment duration. In conclusion, it is believed that SHP has great potential as a substitute for meat, in that the flavor, texture, and beany flavor of SHP did not differ significantly from those of PHP.

Recently, it is expected that small hydropower (SHP) could potentially provide sufficient amounts of alternative energy in Korea where there is an abundance of potential sites and where social efforts are being made to reduce the emissions of green house gases. In the past, the resources survey for SHP development has been carried out using onsite surveys and paper maps, which incurred a great deal of time and cost. Furthermore, the tools for decision making such as determining development priorities or evaluating feasibility have been considered only economic aspect and focused on the performance characteristics of power generation. However, as the concept of sustainable development has been being advanced in recent years, especially focused on human-social, environmental and ecological in addition to economical sector; the consideration of these multiple criteria has become essential for sustainable SHP development. This study aims to propose the spatial multi-criteria decision making (MCDM) methodology for determining priorities among a number of locations on the planning stage of SHP development using AHP and GIS. The proposed methodology is applied for determining development priorities among the SHP locations in Cho River basin and this study presents the detailed spatial information data and the results of development priorities. As a fundamental work, this study will be beneficial to the future activation of SHP development and will help the decision making in evaluating the feasibility of SHP development.

Small hydropower resources for five major river systems have been studied. The model, which can predict flow duration characteristic of stream, was developed to analyze the variation of inflow caused from rainfall condition. And another model to predict hydrologic performance for small hydropower(SHP) plants is established. Monthly inflow data measured at Andong dam were analyzed. The predicted results from the developed models in this study showed that the data were in good agreement with measured results of long term inflow at Andong dam. It was found that the models developed in this study can be used to predict the available potential and technical potential of SHP sites effectively. Based on the models developed in this study, the hydrologic performance for small hydropower sites located in river systems have been analyzed. The results show that the hydrologic performance characteristics of SHP sites have some difference between the river systems. Especially, the specific design flowrate and specific output of SHP sites located on North Han river and Nakdong river systems have large difference compared with other river systems.

The alarming climate change impacts are demanding the use of renewable energy sources like never before. Hydropower is one of the most cost-effective and environmental friendly energy technology recognized in the world. Big hydropower projects come up with the requirements of huge investment costs along with environmental impacts, whereas small hydropower(SHP) are considered a best solution for the economical source of energy. SHP, basically Run-of-River (RoR) type plants can be sustainable renewable energy sources and given the nature of perennial rivers flowing from steep gradient and rugged topography, feasibility of such plants is equally high in Nepal. The objective of this study is to determine the primary potential sites for the development of RoR type SHP sites using Geo-spatial Information System(GSIS). The use of GSIS enables precise survey of large area within a short period of time. This study has focused on the determination of locations by establishing defined criterions and methodologies and hence have located multiple locations rather than selecting one best location. The approach is applicable for the rapid initial screening of potential locations and results can facilitate detail feasibility study for the technical and economic analysis of SHP in the basin.
