The dehumidifier is key components in painting process of shipbuilding. Many researchers have developed dehumidification means and dehumidifier. As a result, It is applied in building and other industrial fields successfully. However, developed dehumidifier is not appropriate method in production environment of shipbuilding, the present equipment is unconcerned about energy saving. This study is energy saving and performance evaluation on dehumidifier for shipbuilding. The method developed here can be used for dehumidification and dry in shipbuilding.

The purpose of this research was to examine the effect of combined exercise on body composition, blood pressure(BP) and insulin resistance in hypertensive patients. 40 subjects were divided into combined exercise (n=20) and control (n=20) groups. The combined exercise was composed of aerobic and resistance exercise program. Body composition, BP, insulin resistance of all subjects were measured at before and after the program participation. Body weight, % body fat, waist circumference, systolic and diastolic BP were significantly decreased within exercise group, and exercise group was shown that there were significant differences of % body fat, waist circumference and lean body mass, and BP, compared with control group. However, insulin resistance was not shown that there was any significant difference within and between group. In summary, combined exercise could improve the levels of body composition and BP.

The purpose of this research was to examine the effect of tennis exercise and plyometric training on physical fitness and forehand stroke function in male university students. 30 subjects were divided into control (C, n=10), tennis exercise (T, n=10) and tennis exercise + plyometric training (TP, n =10) groups. TP group was given to utilizing plyometric training with the intensity of 8 repetitions×1 set~10 repetitions×3 sets for 20~30 minutes, 3 days a week for 8 weeks of tennis exercise (5 days/week). Physical fitness (strength, muscular endurance, power, agility, balance, and flexibility test) of all subjects were measured at before and after the experiment. Forehand stroke function (accuracy, velocity and form of forehand stroke) were measured only after they participated in the 8 weeks exercise program. Grip strength, back strength, half squat jump, sargent jump and two hand medicine ball put were significantly increased within T and TP group. On the other hand, situp, side step, one leg standing with eyes closed, and sit and reach were significantly increased only within TP Group. Furthermore T and TP Groups also were shown that there was a significant difference of back strength, compared with C group. TP Group was shown that there was a significant difference of sit-up, compared with C and T group. TP Group also was shown that there were significant differences of sargent jump and shuttle run, compared with C group. Accuracy and form of forehand stroke were not shown that there was any difference between group. However, TP group was shown that there was a significant difference of the velocity of forehand stroke, compared with T group. In summary, when considering the above results, we concluded that combined treatment of tennis exercise and plyometric training could improve the level of physical fitness, and it could ameliorate the velocity of forehand stroke.

The purpose of this study is to determine the expression of a acute endurance exercise both in cold(2℃) and hot(34℃) temperatures on the skeletal muscle. The main purpose of this study is to the effects of cold and hot temperatures to the heat shock protein 70, heat shock protein 27 and blood lactate, plasma CK using rats as the exercise. Adult male Sprague-Dawley rats were randomly placed in one of three temperature groups (normal, hot, cold). The treadmill run with an intensity of 26m/min, 10°intensity and soleus(SOL) and extensor digitorum longus(EDL) muscle extracted at 30, 60, 90 min during the exercise. The western blotting analyzed the expression of HSP70 and HSP27 during the exercise, the increased HSP27 protein in the SOL and EDL tissues of the cold, hot and normal temperatures were observed. However, it was observed that only SOL tissues increased HSP70 protein in both cold and hot temperatures. These results implied that increased apoptotic factor by cold and hot temperatures could cause the expression of HSP70 and HSP27 which involve cell damage in early stage of exercise and due to temperatures.
Streptozotocin유도 당뇨병 흰쥐의 6주 고강도 트레이닝이 항산화효소와 염증관련 Cytokines의 발현에 미치는 영향

The purpose of this study was investigate the effects of high intensity endurance exercise on expression of antioxidant ensymes and inflammatory cytokines in diabetic rats whose symptom was induced through the use of 50 ㎎/㎏ streptozotocin, 28 white rats were experimented. rats in four groups exercised(Control, n=7, Control-Training Exercise, n=7, Streptozocin, n=7, Streptozocin-Training Exercise, n=7) on a treadmill run with an intensity of 27m/min, 10°intensity inclination five times for a week during 6 weeks. Mer exercise training, blood glucose(p<.05) were significantly decreased in diabetic exercise groups. SOD, IL-10 levels(p<.05) were significantly increased and MDA, TNF-α, IL-6 levels(p<.05) were significantly decreased after high intensity exercise training. However, IL-1β and IL-4 levels(p<.05) were no significantly increased after exercise training. These findings indicate that the regular physical exercise has marked anti-inflammatory effects on diabetic mellitus.
