The purpose of this study was attempted to identify the effects of combined aerobic exercise and anaerobic exercise course on blood lipid and hormone. This study divided 24 healthy college students into the group of aerobic exercise after resistance exercise(n=8), the group of resistance exercise after aerobic exercise(n=8), and the control group(n=8) and thereby conducted a combined exercise program of different order for 12 weeks. Resistance exercise was conducted 4 times a week with the intensity of 60~70% of 1RM during the 1st through 8th week and the intensity of 70~80% of 1RM during the 9th through 12th week. Aerobic exercise was conducted 4 times a week with the intensity of 60~70% of maximum heart rate during the 1st through 8th week and the intensity of 70~80% of maximum heart rate during the 9th through 12th week. The results are as follows. TC, TG and DHL-C were significantly decreased in both groups after exercise and the decreased values were similar in each other group. However, HDL-C were significantly increased in the group of aerobic exercise after resistance exercise. And HDL-C were significantly higher in the both exercise groups than the control group after the 8, 12 weeks of exercise. Growth hormone were significantly increased in the group of resistance exercise after aerobic exercise. Testosterone were significantly increased in the both exercise groups after exercise. And Testosterone were significantly higher in the both exercise groups than the control group after the 8, 12 weeks of exercise. In conclusion, The both exercised groups showed a similar effect regardless of the order of execution of exercise in the elements of blood lipid and hormone.

The purpose of this study was attempted to to identify the effects of combined resistance exercise and aerobic exercise course on health-related, and energy substrates. This study divided 24 healthy college students into the group of aerobic exercise after resistance exercise(n=8), the group of resistance exercise after aerobic exercise(n=8), and the control group(n=8) and thereby conducted a combined exercise program of different order for 12 weeks. Resistance exercise was conducted 4 times a week with the intensity of 60~70% of 1RM during the 1st through 8th week and the intensity of 70~80% of 1RM during the 9th through 12th week. Aerobic exercise was conducted 4 times a week with the intensity of 60~70% of maximum heart rate during the 1st through 8th week and the intensity of 70~80% of maximum heart rate during the 9th through 12th week. The results are as follows. 1. Changes of the health-related physical fitness In the changes of body composition through which we can know the degree of obesity. Body fat significantly decreased in both groups after 8 weeks and the decreased values were similar in each other group. However, the group of aerobic exercise after resistance exercise showed a significant increase of LBM after 8 weeks. We think that the method of aerobic exercise after resistance exercise was more effective than the other type of program. In the changes of physical fitness, flexibility, muscular endurance, muscular strength, and cardiovascular endurance of both exercised groups significantly increased compared to a control group. However, the increased values in both exercised groups showed similar results. 2. The changes of energy substrates There were no significant differences in glucose and free fatty acid being used by elements of energy substrates between the group of aerobic exercise after resistance exercise and the group of resistance exercise after aerobic exercise. Lactic acid, however, significantly decreased in the group of aerobic exercise after resistance exercise(0>12 weeks) and in the group of resistance exercise after aerobic exercise (0> 8, 12 weeks) compared to control group, respectively. Ultimately, this study provides evidence that the program which conducted aerobic exercise after resistance exercise is more effective than the program which conducted resistance exercise after aerobic exercise in the aspect of improving body composition. However, the both exercised groups showed a similar effect regardless of the order of execution of exercise in the elements of physical fitness and energy metabolism.

The purpose of this study was to investigate the effect of different exercise intensity on energy substrates and hormone responses. The subjects for this study were 10 healthy male college students, and participated in three exercise trials. At each trial, subjects ran on the treadmill at the respective exercise intensities corresponding to 40%(low), 60%(moderate), 80%(high) of VO2max for 30min bout of acute exercise. The order of the trials was randomly assigned into three exercise intensities by one week. Blood sample was taken from antecubital vein at rest, immediately after exercise, and recovery 30 min. The results of this study are as follow; The concentration of FFA was significantly increased at post-exercise more than rest and recovery 30 min at 40%, 80% of VO2max, and recovery 30 min at 60% of VO2max. The concentration of insulin was significantly decreased at post-exercise more than rest and recovery 30 min at 40%, 60%, 80% of VO2max. The concentration of epinephrine was significantly increased at post-exercise more than rest and recovery 30min at 60%, 80% of VO2max, and in the effect of exercise intensity, at 80% intensity was higher than at 40%, 60% intensities at immediately after exercise. The concentration of norepinephrine was significantly increased at post-exercise more than recovery 30 min at 60% of VO2max, rest and recovery 30 min at 80% of VO2max, and in the effect of exercise intensity, at 80% intensity was higher than those at 40%, 60% intensities, and at 60% intensity was higher than those at 40% intensity at immediately after exercise. In conclusion, the concentration of energy substrate, insulin, epinephrine, and norepinephrine were affected by various exercise intensities.

This study aims to examine the characteristics of the water quality variation in relation to the change of water exchange rate with respect to the development phases of the Pusan port. To clarify the characteristics, water exchange caused by the variations of coastline shape and water surface area was examined by the numerical experiments using the Lagrangian particle tracking model based on 2-D shallow water equation. As the results of numerical experiments, it was proved that the water exchange in the Pusan port was decreased mainly due to the port development and the breakwaters construction. During the port development phases from 1875 to 1998, 35 % of the sea-space in the port had decreased to make hinterland spaces. This resulted in the loss of wet-land and coastline change as well as decrease of the water exchange rate at the sea side. The city population in that period had rapidly increased from several thousands to 4 millions, resulting in the large discharge of sewages into the port area Under the these environmental conditions, it can be clearly said that the water quality in the Pusan port is sensitively affected by the discharge of urban sewages decrease of the water exchange rate in relation to port and urban developments. In the study, the temporal changes of water quality were discussed with respect to the port development phases. It was clear that the water quality was controlled by the exchange rate change under the port development as well as the input impact into the port from the urbanized city area. To make clean sea of the Pusan port, it is suggested that the sewage control, the water exchange and coastline control should be systematically checked under the concept of eco-friendly development and environmental management.

This study divided 24 healthy college students into group of aerobic exercise after resistance exercise of 8 students, the group of resistance exercise after aerobic exercise of 8 students and the control group of 8 students and thereby conducted a combined exercise program of different order for 12 weeks. This study compared and analyzed the changes of metabolic hormones. Resistance exercise was conducted four times a week with the intensity of 60 through 70% of 1RM during the 1st through 8th week and the intensity of 70 through 80% of 1RM during the 9th through 12th week. Aerobic exercise was conducted four times a week with the intensity of 60 through 70% of maximum heart rate during the 1st through 8th week and the intensity of 70 through 80% of maximum heart rate during the 9th through 12th week. The conclusions are as follows. Epinephrine were significantly higher in both the group of aerobic exercise after resistance exercise and the group of resistance exercise after aerobic exercise than the control group after 8 weeks of training and showed a similar results in the two groups. Insulin significantly decreased in the group of resistance exercise after aerobic exercise, and norepinephrine significantly increased. They were a more effective method in the results by the type of program. As a result, the exercise program to conduct aerobic exercise after resistance exercise among different types of combined exercise program was effective in relation to the degree of obesity following the purpose of execution of exercise. In the changes of metabolic hormones, the exercise program to conduct resistance exercise after aerobic exercise was more effective for lipid metabolic by decreasing insulin levels. In relation to the elements of physical fitness and energy metabolism, the two groups showed a similar effect regardless of the order execution of exercise.
