Anaerobic/aerobic reactor system was used to treat a synthetic wastewater with glucose as carbon sources(0.38~2.29 kg COD/m3.day) and Acid Red 14(1.05 "24.00 g Acid Red 141m3.day, color degree of 570 ~ 1710). COD removal efficiency by the anaerobic stage in operation period were above 90 % organic loading rate of 0.38 ~ 2.29 kg COD/m3.day(except, adaptation period) and the removal efficiency of the whole system were above 96 %. The decolorization of the Acid Red 14 was through the alteration of the dye structure(or cleavage of the Azo bond) during the anaerobic treatment. In the A/A system, the anaerobic stage played an essential role in removing both color and COD. In addition it also improves biodegradability of dye f3r further aerobic treatment. After operation, average MLSS concentration of anaerobic sludge reactor, anaerobic fixed-bed reactor and aerobic fixed-bed reactor were 17100mg/L, 20000mg/L, and 10000mg/L, respectively.

The purpose of this study was to investigate the effects of low-intensity cardiac rehabilitation exercise on the cardiac function and the degree of fibrosis in an older white rat model. This study used male Sprague-Dawley white rats that were 50 weeks old. After the acute myocardial infarction induction, Twenty of the rats were randomly allocated into an experimental group and a control group, and each of the groups consisted of 8 rats. In the experimental group, the exercise was conducted for six weeks, 30 minutes a day, five days a week, using a Rotarod treadmill for animals. The degree of myocardial fibrosis was significantly repressed in the experimental group($13.69{\pm}1.90%$) and in the control group($15.67{\pm}1.54%$)(p<0.05). However, fractional shortening and ejection fraction did not show a significant difference. The results of this study suggest that cardiac rehabilitation with low intensity treadmill exercise repress the myocardial fibrosis.

To investigate the status of irrigation water use and the degree of repeated use of irrigation water, observations for water balance analysis were made during the irrigation periods in 1986 and 1987 crop year. The total area of studied site is 1,441 ha. The site is a major portion of Jedaecheon basin which is located in Bubuk-myeon, Miryang-gun, Gyeongnam Province. The studied area was subdivided into six small blocks. The water balance analysis for these subdivided blocks were carried out considering characteristics of each block. Obtained results are as follow: 1.In mountainous sloppy paddy area(less than 7% slope), the surface inflow was 5A mm/day in average that is one third of the surface inflow into plain paddy area ; 16.7 mm/day. 2.The surface inflows at the vegetative stage and the ripening stage were 15.5 mm/day and 10.4 mm/day, respectively. Those figures were larger than the actual consumptive use at respective same stages ; 13.3 mm/day and 9.2 mm/day, respectively. Whereas, the surface inflow at generative stage was 12.5 mm/day which was less than 14.0 mm/day ; the actual consumptive use. 3.The range of the variation of water storage term was 1 mm/day. This means that there were no change in depth of ponded water on paddy fields. The relationship between the variation of water storage(AS) and the variation of ground water table(H) could be expressed as follow: : AS=0.14H+0.26 4.The ground water inflow: into the transition region ; paddy fields which are located continuously from the mountainous area to the plain area, was larger than the out flow from this region, in general. Rowever, in the plain region where the ground water utilization was predominant, the ground water outflow from this region was larger than inflow: to this region. The relationship between the ground water flow(G2- G1) and the consumptive use in large paddy area(D1-D2) could be expressed as follow: (G2-G1) =0.95(D1-D2) -3.79

Purpose. To determine the effects of music therapy on pain, discomfort, and depression for patients with leg fractures. Methods. Data were collected from 40 patients admitted in an orthopedic surgery care unit. The subjects included 20 intervention group members and 20 control group members. Music therapy was offered to intervention group members once a day for 3 days for 30-60 minutes per day. Pain was measured with a numeric rating scale and by measuring vital signs. Discomfort and depression were measured with self-administered questionnaires. Results. Patients who received music therapy had a lower degree of pain than patients who did not receive music therapy as measured by the numeric pain score (p < 0.001), systolic blood pressure (p < 0.01), diastolic blood pressure (p < 0.001), pulse rate (p < 0.001) and respiration (p < 0.001). Patients who were provided with music therapy also had a lower degree of discomfort than patients who were not provided with this therapy (p < 0.01). Effects of Music Therapy on Pain, Discomfort, and Depression for Patients with Leg Fractures Conclusions. These results demonstrate that music therapy is an effective method for decreasing pain and discomfort for patients with leg fractures.

Purpose: The purpose of this study was to determine the effects of music therapy on postpartum blues and maternal attachment of puerperal women. Methods: The research design was a nonequivalent control group non-synchronized design. The participants were puerperal women who agreed to participate in this study and through a convenience sampling, 60 puerperal women were recruited (30 in the experimental group, 30 in the control group). After measuring postpartum blues and maternal attachment, music therapy was provided to the experimental group over 40 min, once a day, and for 8 days. Then, postpartum blues and maternal attachment for the experimental and control group were measured again on the 8th day. The data were analyzed using the SPSS WIN 12.0 Program. Results: The first hypothesis that "the degree of postpartum blues for the experimental group who participated in music therapy would be lower than that of the control group" was accepted (t=4.350, p<.001). The second hypothesis that "the degree of maternal attachment of the experimental group who participated in music therapy would be higher than that of the control group" was accepted (t=4.828, p<.001). Conclusion: These findings indicate that music therapy has positive influences on decreasing postpartum blues and increasing maternal attachment of puerperal women.

Growth and development of a plant over a growing season is closely related to the daily accumulation of heat. Heat unit measured by accumulated growing degree days (GDD) is becoming increasingly popular to estimate the growth of a plant or even in insect. GDD or heat accumulation per day is measured by calculating average daily temperature and then subtracting the base temperature below which growth does not occur. Heat accumulation per day is added for the desired period and accumulated GDD is determined. The present study was conducted in five seasons in an established garden with K-2, S-36 and V-1 mulberry varieties belonging to Morus indica L. grown under completely irrigated condition at the farm of CSRTI, Mysore during 2001 - 2002. Plants were pruned in each season and the growth of the plant measured by total shoot length and fresh leaf yield was recorded at an interval of 5 days starting from 30 days of pruning (DAP) to 70 days when all the plants were pruned. The accumulated GDD for the corresponding days were recorded and used for analysis. Accumulated growing degree days (GDD) have been found to be perfectly correlated with both growth and yield in all the seasons in all the varieties studied. The high $R^2$ values indicated a strong relationship between the accumulated GDD and, growth and yield of mulberry.
