  • The purpose of this study is to examine the effect of milk protein intake and band exercise on active fitness and metabolism risk factor of elderly women for 8 weeks. The two groups were classified into one group(TG) with milk protein intake and band exercise both, and the other group(CG) that was controled. The group of TG was applied doing milk protein intake 3 times for a day, and doing band exercise 4 times for 60 minutes a week. The intensity of the exercise was RPE<17. Each measurement variable was measured before and after 8 weeks to investigate the effect. This study got the result with this step. First, TG has shown small interaction with active fitness. Second, TG has shown small interaction with metabolism risk factor. Therefore, this study gives us the positive result of the effect of milk protein intake and band exercise on active fitness and metabolism risk factor of elderly women for 8 weeks. However, it has limitation to verify effect of milk protein intake and band exercise.

  • The purpose of current study was to investigate the correlations of walking exercise program-induced abdominal visceral fat loss with metabolic syndrome risk factors in middle-aged women. The walking exercise program was provided at a frequency of 3 sessions, respectively, per week for a duration of 12 weeks. Then, the subjects were classified into either those whose abdominal visceral fat loss belonged to low 25 percentile (low 25% group, n=8) or those whose abdominal visceral fat loss belonged to high 25 percentile(high 25% group, n=8) based on the amount of abdominal visceral fat loss induced by the walking exercise. Metabolic syndrome risk factors(waist circumference, triglycerides, HDL-cholesterol, fasting blood glucose, blood pressure) between groups according to the 12 weekly walking exercise program had no difference. In conclusion, the findings of the present study show that the walking exercise-induced total abdominal fat and visceral fat loss were positively relate to waist and blood pressure(SBP, DBP) and that the walking exercise-induced subcutaneous fat loss were positively relate to waist and blood pressure(SBP).

  • The species composition and seasonal variations of fish community in the Zostera marina belt at the coastal water off Hamduck, northern part of Cheju Island, were analyzed based on day and night samples collected by a small beam trawl from May 1993 to May 1994. The dominant species among the 58 fish species in 35 family were tubesnout, Aulichthys japonicus, gobie, Pterogobius zonoleucus, filefish, Rudarius ercodes, pipefish, Syngnathus schlegeli and sea catfish, Plotosus lineatus. These species comprised 86.1% in the number of individuals and 62% in biomass. The number of individuals and biomass were high between October and December, and low between January and April. About 90% of fishes were noncommercial and small-sized fishes, less than 14cm in total length. The larvae and juvenile fishes were collected in the study area throughout the year. The recruitments of dominant species were related to the seasonal variations of Z. marina utilized as a shelter or feeding ground. A japonicus, P. zonoleucus, Zoarchias glaber and Hexagrammos agrammus recruited between January and June, and R. ercodes, S. schlegeli, P. lineatus and Petroscirtes breviceps between July and December.

  • This study was carried out to compare the characteristics of hydraulic architecture by measurement of leaf specific conductivity(LSC) in the twenty-one deciduous broad-leaved species. The LSC's of stems were higher than in branches except Acer mono, A. triflorum, Betula schmidtii, Fraxinus rhynchophylla and Zelkova serrata, and lowest in junction parts as compared with stems and branches. In diffuse-porous species, the LSC was much higher in B. plalyphylla var. iaponica, B. schmidtii, Cornus controversa, Tilia amurensis than those of other species and especially lowest in A. triflorum. In ring-porous species, the LSC was much higher in Maackia amurensis, Paulownia tomentasa, Quercus aliens, Q. serrata than those of other species and lowest in Ulmus davidiana var. japonica. The LSC's of 1-year-old terminal shoots of stem(the leader and adjacent laterals) in A. triflorum, C. controversa. F. mandshurica, Q. mongolica and Z. serrata ranged from 22 to $139{\mu}{\ell}/g$ in the leaders, and 11 to $73{\mu}{\ell}/g$ in the adjacent laterals. The LSC's of leaders were usually greater than the adjacent laterals because of the hydraulic dominance of the leader shoot.

  • The purpose of this study is to find the light intensity which induced maximum gathering rate and to observe the variation of the gathering rate both at daytime and night by using Sea-bass, Epinephelus septemfasciatus (Thunberg). An experimental tank (360 L×50 W×55H cm) was set up in a dark room. An illumination system was attached to the end of one side of the tank to control horizontal light intensity. Eight artificial light sources were prepared by combination of three with white light bulbs (10W, 60W, 100W) and eight filters. During the experiment water depth was maintained 50cm level in the tank. The tank was marked into six longitudinal sections each being 60cm long to observe the distribution of fish. The fish were acclimatized in dark condition for 50 minutes before the main experiment. Upon turning on the light, the number of fish in each section was counted 60 times every 30 seconds, and the gathering rate was obtained from the average number of fish in each section. The light intensity inducing maximum gathering rate was 24.13 lux (15.25~35.93 lux) at daytime and 0.41 lux (0.25~0.63 lux) at night. The variation of the gathering rate of fish in illumination time was great and did not show any definite pattern but fluctuated irregularly. Its different between daytime and night is remarkable.

  • This study aimed to qualify the amount of movement during game-based training and competition by using a GPS and to identify the non-contact injury risk in lower extremities for female field hockey enrolled in Korean national team. A total of 52 players were participated in this study and their GPS data collected during training and competition were averaged for 1 week and 4 weeks. And then, an injury risk in lower extremities was calculated for each category of the amount of movement in GPS variables that were related to non-contact injury. In forwards, the injury risk was the lowest in the moderate-low category of total distance covered and repeated high-intensity effort bout and the high category of high intensity distance for 1 week, but the risk decreased as the amount of high intensity distance increased for 4 weeks. In midfielders, the injury risk was the lowest in the low category of total distance covered, high intensity distance, repeated high-intensity effort bout and deceleration bout for 1 week.

  • This study measured the quality of Elderly Day Care Services by surveying service users; data were analyzed to see the causality between quality of services, customary satisfaction, referral intention, and repurchasing intention, and to find out the mediating effect of customary satisfaction. The quality of Day Care Services has been measured based on the SERVQUAL model, and structural equation model has been used to observe the causal connection between the five factors, tangibles, reliability, responsiveness, assurance and empathy, and customary satisfaction, referral intention, and repurchasing intention. The following is the main result from the causal effect model affecting the customary satisfaction and repurchasing intention by five quality factors of the service quality. First, it was shown that tangibles and responsiveness, as quality factors, directly affected the customary satisfaction, and reliability, credibility, and empathy did not. Second, it was shown that tangibles, reliability, responsiveness and empathy, quality factors, did not directly affected the referral intention and the repurchasing intention. But the effect of service quality on referral and repurchasing intention was mediated by customer satisfaction. Third, it is shown that customary satisfaction directly affected the referral intention and the repurchasing intention.

  • In this study, the operational characteristics of a cam-type vegetable transplanter which usually used in domestic was analyzed and operating mechanism of a transplanting device was analyzed. The main components and power path of the transplanter were analyzed. The maximum and minimum control cycles according to the moving speed and the plant spacing were analyzed. 3D modeling and simulation were performed to derive the trajectory of the bottom end of the transplanting hopper and the plant spacing at the each operating condition. The simulation results were verified by the field tests. As main findings of this study, the transplanting device has one degree of freedom (DOF) which consist of 13 links, 17 rotating joints and 1 half joint, and each part has composite structure with cam and links. By continuous and repetitive motion of the structures of transplanting device, the transplanting hopper plants the seedling in the ground with a vertical direction, and the seedling was planted stably. The power is transmitted to the driving part and transplanting device from the engine, and the maximum and minimum plant spacing of the transplanting device were about 900 mm and 350 mm, respectively.

  • An experiment was conducted at the Yeongnam Crop Experiment Station to obtain basic informations about cultural techniques for high yield by manipulating plant spacing in association with seedling number. Cultivars showing relatively low competition index within or between rice hill were Palgongbyeo, Milyang 83. Milyang 90 and Sangpungbyeo, while those with high competition index were Pungsanbyeo, Samgangbyeo, Weongpungbyeo, Taebaegbyeo and Dongjinbyeo. Variations of agronomic characters such as culm length, spikelets per panicle, grain yield per panicle among each culm within hill were not interrelated among the characters. This phenomenon was also same within and between cultivar groups. However, cultivars having high competitive ability showed relatively low variation in agronomic characters. There was a trend that most of rice cultivars had a high positive correlation between total competition index and rice grain yield. Competition index between rice hill was more significant than that of within rice hill for Tongil type cultivars except Milyang 83 which belonged to low tillering capacity while both types of competition index within and between hill were important for Japonica type cultivars and Milyang 83 of Tongil type cultivar to increase rice yield.
