Ca Ionophore, A23187에 의한 30A-5세포의 지방세포 분화 억제

이권행,윤경하,한만덕 순천향대학교 1993 논문집 Vol.16 No.1

지방세포 분화 억제 과정에서 ??의 역할을 알아보기 위해, 30A-5 preadipocyte가 지방세포로 분화되는 과정에 ?? ionophore, A23187을 첨가하여, 30A-5세포의 지방세포 분화도와 acetyl-CoA carboxylase 활성을 검토하였다. 30A-5 preadipocyte는 insulin과 dexamethasone의 존재하에서 성숙된 지방세포로 분화되는데, 세포가 분화되는 과정에서 1 μM의 ?? ionophore, A23187을 가하면 30A-5 의 지방세포로의 분화가 거의 완전히 억제된다. 30A-5 세포가 지방세포로 분화되는 과정에서 비례적으로 증가하는 지방산 합성의 조절효소인 acetyl CoA carboxylase의 합성은 ?? ionophore, A23187처리에 의해 억제하는데, 30A-5 세포의 지방세포 분화억제는 acetyl-CoA carboxylase합성 저하에 따른 결과로 추측된다. ?? ionophore, A23187에 의한 acetyl-CoA carboxylase 의 합성저하는 비교적 장기간에 걸쳐 나타나는 효과로, 이 억제효과는 ??의 세포막이동의 경쟁적 저해제인 ??에 의해 부분적으로 극복된다. 따라서 A23187에 의한 acetyl-CoA carboxylase의 합성저하와 이에 따른 지방세포로의 분화를 억제하는 과정의 signal tranduction 과정에는 ??의 이동이 중요한 역할을 할 것으로 추정된다. To examine inhibitory effect of ?? ionophore, A23187 on adipocyte conversion of the 30A-5 preadipocytes, we checked the degree of differentiation and acetyl-CoA carboxylase activity of 30A-5 cells in the presence and absence of ?? ionophore, A23187. Inhibition of differentiation of 30A-5 preadipocytes into matured adipocytes was almost completely inhibited by ?? ionophore, A23187. Inhibition of differentiation of 30A-5 cells be resulting from decreased synthesis of acetyl-CoA carboxylase, which is regulatory enzyme in de novo fatty acid synthesis, by ?? ionophore, A23187. Decreased synthesis of acetyl-CoA carboxylase by ?? ionophore, A23187 might be one of the long term effect, and this inhibitory effect was partially recovered by ?? which is competitive inhibitor in membrane transport of ??. Therefore we assumed that ?? mobilization may play a important role on signal tranduction process in inhibitory action of 30A-5 preadipocytes into adipocytes.

The purpose of this study was to investigate the effect of interval weight training on the Fat Weight and Body Density. We have selected 24 students from the K-university whom they are studying physical Education. And also divided into 2 groups; control group with 12 students and the other is Training group with 12 students. We have tried interval weight training 3 days in a week on Monday, Wednesday and Friday. To notify the changes of Body Density, We have measured subscapular, triceps, suprauliac, and Abdomen. And also to notify the changes of Fat Weight, We have measured % Fat and L.B.M(Lean Body Mass) The first measurement took before training and the second measurement took after 6 weeks of training. And the results were as follows: 1.For skinfold thickness to control group, the total of 4 parts were 42.15±11.77mm but after 6 weeks it increased to 47.05±12.19mm, but for training group it was 33.56±5.02mm but after 6 weeks training it decreased to 31.45±4.39mm. 2.For fat weight to control group, before training it's 11.17±1.98kg but after 6 weeks it increased to 12.20±2.23kg. For training group, before training 12.20±2.23kg but after 6 weeks it decreased to 9.46±2.52kg. 3.For % fat, control group before training 14.71±2.98% but after 6 weeks it increased to 15.66±3.02%. For training group, before training 13.47±2.11% but after 6 weeks it decreased to 12.52±2.74%. 4.For L.B.M(lean body mass), control group didn't show much of difference before and after the training but for the training group it showed 59.66±7.02kg before training but after 6 weeks it increased to 60.12±6.35kg. For training group, before training 59.84±3.65kg but after 6 weeks it decreased to 60.55±2.99kg.

고속 중성자가 조사된 원자로 용기 강재의 운전온도에서의 Mossbauer 효과 연구

이경행,윤인섭,장기상 尙志大學校 1998 論文集 Vol.19 No.-

The changes of physical properities of the reactor vessel steel (SA 508 class 3) irradiated by fast neutron have been investigated by Mossbauer spectroscopy at operating temperature 600K. The various physical properties of the reactor vessel steel irradiated by neutron are changed because fast neutrons (over 1 MeV) are created in operating nuclear vessel. The crystallization of the samples is disappeared by increasing of neutron irradiation. In the Mossbauer spectrum of the sample, the lattice sites are three types. Two sites of them are ferromagnetic and the other one is paramagnetic. The Mossbauer parameters of the paramagnetic site are predominatly changed than the others.

In order to obtain basic information on nutrient intake of residents in rural community during the summer that can be used as reference material for making health policy in the future, a three day survey has been conducted at Jeomdong-Myun, Yeoju-Gun, Kyunggi province which is the pilot project area for the project implemented by the Community Health Development Committee, Korea University. The sample size was 46 households and the major findings were as follows; 1. The number of foods they were taking totalled 16 categories and 152 kinds. 2. Average amount of daily intake was 1,124 grams per person of which 93% was vegetable food, and animal food occupied only 7%. Amongst the animal foods, the intake amount of fishes and milk was lower than the national average. 3. The nutrient intake except fatty substance and calcium, namely protein, carbohydrate, phosphorus, iron and vitamines, was exceeding the recommended daily allowance for adult. The same fact was also found in terms of the total calorie intake. 4. The problems on the nutrient intake arisen from the study in this area were; a. The proportion of animal protein occupies 24% of the total protein intake whereas the national average of rural community stood at between 32.5%∼33.5% as a results of 1981∼1984 National Nurition survey. b. Insufficient intake of fat and oil, and c. Calcium intake occupies only 72% of the recommended daily allowance and 84.5% of the calcium intake was depending upon vegetable, which has a low absorbability. As described above, the intake of animal protein, fatty substance and calcium was low because of the high dependency on vegetable food in this community.

政府政策에 대한 壓力團體 활동의 理論模型에 관한 公共選擇論的 硏究

金幸範,文景柱 인제대학교 1997 仁濟論叢 Vol.13 No.1

The role of interest group in policy process cannot be emphasized too much. But there are variant approaches to this policy subject. Public Choice approach is new promising focus in the study of public administration as was suggested by Vincent Ostrom. This article reviews interest groups(pressure group) which were analyzed by the approach of economic model. We selected four models as a typical topics : (1) Olson Model, (2) Peltzman Model, (3) Virginians Model. (4) Becker Model. all of them were reviewed in desultory fashion by the policy scientist perspective. Each model was reviewed in separate section. We could identify the strength and the shortcomings of the models. Even though 4 models were built on the same economic perspectives, they show different implication, in both description and prescription, some of which are contrasting rather than being just different. Comprehensive comparison of these models needs common standard, so that we could make an useful conclusion on interest group and its role in policy process. But it was difficult to devise such common standard by which we can do comparison. Despite the danger of arbitrariness, five standards were extracted for comprehensive comparison of the models. According to such comparison following conclusion were derived. ① Olson Model is the model focusing on the formulation and establishment of the interest group : It concentrates on internal management of members of group to avoid free riding, and then to establish interest group. All others are models on 'activity', not formulation, of already well-established interest group. ② They suggest disparate preference for the competitiveness of the interest groups. According to Olson model competitiveness of the interest groups harms national economic growth. But Peltzman model does not make clear view on the competitiveness of the interest grouts. Virginians model most strongly emphasizes the harmful effect on the social welfare, by inventing the concept of 'rent-seeking' Becker stands at far different position : he suggests competitiveness of the interest groups results in efficiency, rather than inefficiency, in subsidy and taxation. ③ On the active phase of government which is a supplier of regulatory policies, we could find some difference, too. Olson model ignores the active role of regulator. In Peltzman's model, regulator is not just a captive of the regulated; he considers the both sides of beneficiary group and non-beneficiary group. Peltzman appears to recognize a little more active role of regulator than Olson. Virginians regard government as an active creator of the rent which interest groups are eager to win. Becker model regards role of the government just as that of pluralists. ④ Which interest group is going to be winner in policy benefit distribution? Olson model, when we extend his logic on the formulation of interest group to this problem, seems to consider the small group the future winner. Peltzman model says both producer interest group and consumers interest group can be the winner. Virginians never make it clear which group is going to win ; they just focus on total and mutual activity which result in the harmful effect on social welfare. Becker model suggests relatively efficient group is going to be winner. ⑤ On the prescription to evade undesirable result of. interest groups, Olson suggests restoration of free market. Peltzman model is not sensitive to the possible undesirable effect of interest groups on societal welfare ; he, therefore, does not show clear comment on the prescription to that problem, either. Virginians are easer to devise effective ways to remove inefficiency caused by interest groups and their rent-seeking activity. Their fundamental remedy seems to be constitutional change to decrease the power for government to create rent. Becker suggests perfectly different prescription ; the strengthening of the activity and competition among interest groups.

최행숙,김은경,백성혜,이길재,정완호 한국교원대학교 과학교육연구소 2001 청람과학교육연구논총 Vol.11 No.1

In this study, the contents of elementary school science textbooks related to 'heat and temperature' are analyzed and alternative conceptions of "heat and temperature" among students enrolled in grades 4, 5 and 6 are investigated. 259 students were selected from a elementary school located in urban area. The relationships between students' alternative conceptions and the content of elementary science textbooks are also examined. Students' conceptions are analyzed from their answers to a paper-and-pencil test. The typical alternative conception of "heat and temperature" held by students was follows. They think that "heat" is a material and "temperature" is value of heat amount. They can't distinguish between "heat" and "temperature". Their explanation of "heat and temperature" is focused on hot or cool sensation and other observable characteristics of a material. A textbook analysis indicated that contents on "heat and temperature" were organized without the viewpoint of particle motion theory. This may be one of the causes of students' alternative conceptions.
