Thin-walled muLticell box girders subjected to an eccentric load can be produced the three global behaviors of flexure, torsion, and distortion. Specially in railway bridges subjected to much eccentric load, it is quite important to evaluate influences of torsion and distortion. But it is very difficult to evaluate each influences of major behaviors numerically. If we can decompose an eccentric load P into flexural, torsional, and distortional forces, we can execute quantitative analysis each influences of major behaviors. Decomposition of Applied Load for Thin-walled Rectangular multi-cell box girders is reserched by Park, Nam-Hoi(Development of a multicell Box Beam Element Including Distortional Degrees of Freedom, 2003). But researches about trapezoidal multi-cell section is insufficient. So, this paper deals with multi-cell trapezoidal box girders. An expanded method, which is based on the force decomposition method for a single-cell box girder given by Nakai and Yoo, is developed herein to decompose eccentric load P into flexural, torsional, and distortional forces. Derive formulas by decomposition of eccentric load is verified by 3D shell-modelling numerical analysis.

The purpose of this study was to determine the effects of Circuit Weight Training(CWT) serum antioxidant activity in obese high school girls. The subjects were 11 obese highschool girls(BMI?27kg/m²). They were to perform the Circuit Weight Training with 40~55% intensity of 1RM, for 50 rains/day, 3 times/week during 12 weeks. Before and after training, 10 me blood was extracted from the antecubital vein of each subject for the purpose of analyzing its effects on serum antioxidant activity. The conclusion of this study is as follows: 1. In serum antioxidant activity profile after 12-week Circuit Weight Training was increased significantly in H2 02, ·OH, MDA. 2. In serum antioxidant activity profile after 12-week Circuit Weight Training was decreased significantly in GSH, Uric acid.

The purpose of this study is to examine the rating of perceived exertion at lactate threshold for exercise prescription. The number of experimental subjects were forteen. The endurance training intensity corresponding to lactate threshold(LT) was administered 30 minutes a day, 3 days a week, for 8 weeks. The results of study were as follow ; 1. The mean VO₂max of control subjects were 3.42 l/min and 3.36 l/min before and after training. And that of experimental subjects were 2.69 l/min and 3.80 l/min before and after training. 2. The mean VO₂max at lactate threshold in control subjects were 2.21 l/min and 2.03 l/min before and after training. And that of experimental subjects were 2.20 l/min and 2.79 l/min. 3. The mean RPE-LT corresponded to a perception of work as "fair light" and "Hard." 4. The endurance training decreased RPE scale significantly during the maximal exercise.

Objective : This study is performed for the purpose of examining the efficacy of the scolopendrid(Scolopendra morsitans L) which has been to low back pain as a folk remedy. Methods & Results : Seventy patints with H.I.V.D. treated with the scolopendrid aquacupuncture and examined 4 tests; D.I.T.I., physical test, Oswestry disability index, and self-conscious pain rate were studied. And we follow up after discharge, we evaluated the present state and recovery period. Or we evaluated by herniated type and duration of onset. There was 58~97% of efficacy rate in each tests. Moreover, statistically valuable change in all 7D.I.T.I. points and in disability index and in self-conscious pain rate was showed. Conclusion : The scolopendrid aquacupuncture is possible to be effective terating the H.I.V.D patients. so we suggest the possibility using this new remedy to the H.I.V.D. patients.

The study of the herbaceous species association in the larch forest of Mt. Chungkyeu was carried out from April to October, 1980. 1. The herbaceous ground association was consist of 43 species, Oplismenus undulatifolius, Festuca ovina, Oalamagrostis arundinaceae var. brachytricha and Carex pediformis var. rhizina were dominant species. 2. The major herbaceous species, of which important value was above 10, were Oplismenus undulatifolius(28.2%), Festuca ovina(26.7%), Miscanthus purpurascens(26.5%), Calamagrostis arundinaceae var. brachytricha(21.2%), Carex nanella(17.5%), Carex lanceolata(15.4%), Carex pediformis var. rhizina(14.1%), Carex siderosticta(12.7%), Potentilla fragarioides(11.7%) and Artemisia keiskeana(10.5%). 3. Classifying the herbaceous ground association by partial ordination, it was divided into two kinds of association ; Carex-Oplismenus association and Calamagrostis-Oplismenus association. 4. The results of the species association analysis was the same as the ordination. The coefficients of species exhibited the positive value in the same association, on the contrary, it was negative value in the different association.
