The purpose this study was to estimate effects of EPOC and TG/fatty acid cycling on warm water immersion of immediately after exercise. To elucidate the role of fatty metabolism, a sequence of five experiments was performed. Seven physically active, male subjects volunteered to participate in the presented study. The mean values for age, body mass and hight were 25±1.52 yr, 79.2±9.52kg, 177.2±4.62cm, respectively. After giving consent, participant visited the laboratory on six occasion: 1) 30min of treadmill exercise VO2max 55% and a further 60min recovery, 2) 30min partial body warm water immersion in a 39℃ and a further 60min recovery, 3) 30min whole body warm water immersion in a 39℃ and a further 60min recovery, 4) 30min of treadmill exercise VO2mas 55% and in 30min partial body warm water immersion in a 39℃, 5) 30min of treadmill exercise VO2max 55% and in 30min whole body warm water immersion in a 39℃. When compared by recover period within repeat on the base of changes of subjects average body temperature, not effective interactions among repeat. However, partial and whole body warm water immersion immediately after exercise shows it as the best effective exercise for VO2max 55%, partial and whole body warm water immersion. When compared by recover period within repeat on the base of changes of subjects EPOC, effective interactions among repeat(p<.05). Partial and whole body warm water immersion immediately after exercise shows it as the best effective exercise for VO2mas 55%, partial and whole body warm water immersion. The catecholamines concentration was significantly higher partial and whole body warm water immersion than exercise of VO2max 55%(p<.05). The TG concentration and free fatty acid was significantly higher partial and whole body warm water immersion immediately after exercise than exercise of VO2max 55% than Partial and whole body warm water immersion(p<.05). Based on the facts that we have discussed above, human metabolism is increased by both exercise and conditions of immersion and partial and whole body warm water immersion immediately after exercise than exercise of VO2maw 55% shows it as better effective treatment for increasing TG/Fatty acid cycling activation. Due to extremely heavy stress complained by subjects during whole body immersion, it is thought that more researches on it should be required.

It has been proposd that calcium entry from an external medium increases intracellular free calcium to toxic levels during ischemic acute renal failure, and verapamil (ARF) has been suggested as the agentblocking calicium entry into renal cells and protecting renal function during ischemic injury. Polyamines, anorganic cations that play various roles in normal cellular proliferation and differentiation, accumulate in renal failare. Alsa it has been suggested tht the synthesis and metabolism of polyamine are influence by acute changes of the general condition, such as acute renal failure, and are mediated by a calcium influx into the cells. The study was designed to study the protective effects of systemic verapamil pretreatment on renal function and the influence on polyamine metabolism in experimental ischemic ARF in cats. For these purpose, the experimental animals were divided into 2 groups. While Group I (n=5) was an ischemic ARF model by renal artery clamping for 60 minutes, Group II (n=5) was ischemic ARF with systemic verapamil (5 ml/min/kg) pretreatment. The creatinine clearance and plasma and urinary polyamine were measured in each group before and after the renal artery clamp. The results were as follows: 1) Creatinine clearance before and after the renal artery clamp were 10.64±7.18 ml/min/kg and 2.09±1. 70 ml/min/kg in Group I, 4.47±3.38 ml min/kg and 0.60±0.79ml/min/kg in Group II, respectively, So creatinine clearance decreased more significantly in Group II campared with Group I. 2) Plasma polyamine increased after ischemia in Group I. In group I, plasma levels of putrescine, spermidine, and spermine before ischemia were 4.75±0.40 nmol/ml, 0.69±0.09 nmol/ml, and 0.83±0.63 nmol/ml, were elevated to 7.17±2.91 nmol/ml, 9.83±1.46 nmol/ ml, and 2.64±1.14nmol/ml after ischemia. But in Group II, the plasma level of polyamine was not changed, and especially, spermine decreased significantly from 0.83±0.27 before ischemia to 0.49±0.23 nmol/ml after ischenmine (p=0.033). 3) Urine polyamine excretion decreased after ischemia in Group I and Group II. In Group II, urinary excretion of spermidine and spermine before ischemia, 0.13±0.10 nmol/min and 0.17±0.13nmol/min, decreased after ischemia to 0.01±0.01nmol/min (p=0.019) and 0.032±0.26 nmol/min (p=0.0257). 4) In renal tissue, spermine content vas highest. In Group II, preischemic spermine were 397.20 nmol/g and increased to 646.66nmol/g after ischema, But there were no significant changes in the polyamine contents in Group II. From these data, it was suggested that systemic verapamil pretreatment exerts no protective effect on ischemic ARF. Plasma polyamines are elevated in ischemic ARF, and verapamil may protect these elevations.

Dewey와 Bruner의 敎育過程에 대한 比較 考察

It is said that we commit a fault when understood and utilized the theories or conceptions of education in seperation. The purpose of this paper is the establishment of the controversy issue and the search of common features between Dewey and Bruner. ⑴ Quality of experience and Structure: This topic starts under the assumption that Bruner's structure is included within the concept of quality in Dewey. The structure has been apprehended at a time in course of our being interacted with the object. We have had "idea" while devotion of ourself to a puzzle problem. The structure is composed of this idea. Thus, it seems to be included both the subfective conditions (feel) and the objective conditions. ⑵ Interest and Discover: It is known that the educative process in Bruner is systematic in comparison with Dewey's theory. So is the educative process as developmert of interest in Dewey. Its theoritical foundations are brought forward; ⑴ Interest is dependent upon Grouth. ⑵ Interest is working for translation the practical side into the theoritical side. ⑶ By action of interest is acquired the experience in general. ⑷ Through interest we can have knowldeges or concepts omitting the direct experience. ⑸ Interest has the autonomy. ⑹ Interest has the action with the thought. But There is a remarkable contrast between the two in the purposes and background of philosophy. For Dewey, the educative process is individualistic, and is common in Bruner. The former has the noministic view, the subject and the object, idea and data, child and curriculum, interest and effort, while the latter emphasizes the higher mental ability-the dualistic view.

An improved retinal tack can be used to fix the retina in complicated retinal detachment and proliferative vitreoretinopathy. We used the retinal tack made by biodegradable polyglycolic acid, polylactic acid and copolymers. The tacks with polyglycolic acid were placed in the retina the right eyes of 10 rabbits as group 1, with polylactic-polyglycolic acid copolymers as group 2 in each left eyes. We examined the absorption rates and degree of intraocular inflammation at 1 day, 1, 2, 4, and 8 weeks and compared both eyes. The tacks were absorbed with time in both eyes, but more rapid in copolymers. And there was no inflammation in both eyes. Now, this study will be a base on the drug delivery system in intraocular pharmacological and surgical management.

This paper set up the nonparametric test statistic U₂, which expanded U₁-statistic with degree(3,3) into the form of a two-sample U-statistic with degree(5,5), say U₂for the purpose of developing the statistic that may be more efficient than the U₁-statistic suggested by Shetty & Govindarajulu(1988), in a two-sample location test. We compared the U₂test with the previous test, in the sense of ARE, under some special population distributions. To obtain the ARE of teh U₂test w.r.t. the previous test, the asymtotic null distribution and the efficacy of U₂were derived. Conclusively, we discovered that the U₂test expanded to degree(5,5) was more efficient than the previous test in heavy-tailed distributions like the double exponential and Cauchy.
