길용식,김동우,하영철,이광렬,김종락 대한건축학회 2003 대한건축학회 학술발표대회 논문집 - 계획계/구조계 Vol.23 No.1(구조계)

This paper describes on the results of 1:400 geometrical laboratory modeling of wind-induced point pressure on the membrane roof structure of Stadium with variable roof slopes. The wind flow for flat ground surface was simulated in a boundary wind tunnel at Kumoh National Institute of Technology. The roof slope of membrane structure changed into 5 types. The locations of wind pressures taps are distributed on the same upper and lower part of membrane roof. The resultant wind pressure for each measurement points are analysed on 2 categories. One is acting on upper direction, the other is lower direction. The results showed that in the case of upper direction the changes of wind pressures on the membrane roof are not dominant in regard to changing roof slope, but in lower direction wind pressures are increased at the rear part of roof with changing roof slopes.

스웨덴의 近代發展史

The Swedes, living on the outlying northern peninsular, thrust upon the south and helped shape the European history. Between 800 and 1050 A.D., the Vikings, who formed last phase of the Germanic invasions, pushed themselves to the east and south, and thus left profound historic marks on Russia through Black Sea as well as Western Europe. The Swedes' second outward thrust occured during the first half of the 17th century in the form of the Swedish intervention of the thirty-year War, and the Swedish leaders fought for the protestant causes and territorial gains. Meanwhile, Sweden as a whole remained largely secluded, backward and agricultural a society being unaffected by the dynamic changes occurring in the Western Europe during this period. However, the nation has emerged in the twentieth century as an ideal state of peace loving, neutral, welfare minded and most progressive kind. How did this great conversion come about beginning 1870's? What factor contributed to the rapid development that has been much faster than other Western European countries? A process which has taken more than centuries in other societies that the process of industrialization, urbanization democratization and social reform have been achieved in Sweden within the span of half a century. For many centuries, the Swedes were known for adventure and violence; and then the present Sweden is known for the homeland of Nobel prize, great artworks and one of the most advanced technology. How has this come about? The key task ahead is to assess the national accomplishment as a whole, the achievements of individual endeavor and concerted effort on the part of the nation. The Swedes learned the necessity of compromise and adjustment. Competition and burst of energy are channeled toward positive national goals instead of strife and violence. Taking into account that the nation is small and backward, the country was united in striving for independence and excellence. The descendents of the Vikings realized that they form homogeneous community and they are indeed in the same boat, and that a driving for excellence and originality since became national obssession. The success story of modern Sweden would be a major examplar which worth careful examination as well as thoughtful analysis. It should also be noted that the Swedish model could serve as a lesson to other developing countries.

It has been well-known that biliary cirrhosis with concomittant impairment of renal functions were occured after prolonged obstruction of biliary tract. In the present study, an attempt was made to investigate the mechanism of impaired renal function and the ultrastructural change of the kidney in rats, ligated the common bile duct for 21, 28 and 50 days in order to induce secondary biliary cirrhosis. The results obtained were as follows ; 1. Secondary biliary cirrhosis was produced evidently 28 days after ligation of common bile duct. Prominent proliferations of bile ducts and chronic inflammatory cell infiltrations were seen in pehportal area. 2. 28 and 50 days after ligation of common bile duct, show swelling and degeneration of mitochondria, microcystic formation and lysis of endoplasmic reticulum in the hepatocytes. Loss of microvilli in the bile ductules were noted. 3. Focal fusions, edema and bleb formations of foot processes were seen. Electron dense materials with variable size and global shape were found in foot process, 21, 28 and 50 days after ligation of common bile duct. 4. There were slightly thickening of renal glomerular basement membrane with hump in the subendothelial and widening of the mesangial matrix, 28 days after ligation of common bile duct. 5. There were moderately thickening of renal glomerular basement membrane and widening of the mesangial matrix with electron dense deposits, 50 days after ligation of common bile duct. From the above findings of electron microscopy, this study revealed electron dense deposits on renal glomerular mesangium of the rats as a results of experimental secondary biliary cirrhosis by ligation of common bile duct. Also severe hepatic injury due to swelling or lysis of rough endoplasmic reticulum and destruction of bile ductules resulted in deposited electron dense materials due to inhibition of excretion of immune complex through hepatobiliary tract, therefore this change indicated that immuncomplex could be deposited on renal glomerular mesangium.

The results obtained from the experiment to make a comparison between thermal characteristics and chemical reactions of 10% Br-Methanol treated oxides, and inclusions and oxides in 18Cr-8Ni stainless steel can be concluded as follows; 1. It has been shown that when MnO2, Cr2O3, Fe2O3 and SiO2 are heated, they all give exothermic characteristics in the temperature range about 200 to 300℃, but they tend to be heated up endothermically in the range 300 to 900℃, except for the fact that when the reaction 3MnO2=Mn3O4+O2 occurs at 600℃, peak showing endothermic reaction is observed. 2. Specimens made by mixing some of oxides such as MnO2, SiO2, Fe2O3 and Cr2O3 and uheir complex compunds and inclusins have all produced similar reactions which are characterized by showing an exothermic for temperatures of up to approximately 300℃ and an endothermic for the temperature range 300 to 900℃. However, it is noted that some oxides containing Mn give a sharp peak which represents endothermic reaction. 3. Below 100℃ the thermal analysis curves obtained from specimens made by reacting each complex compound with 10% Br-Methanol have been shown to be similar to these for specimens not rected with 10% Br-Methanol, showing endothermic heating for temperatures from about 150 to 200℃ endothermic heating for higher temperatures than 200℃. 4. The X-ray diffraction analysis has shown that oxides such as Mn3O4 and Cr2O3 are observed from the complex compound with a ratio MnO2: Cr2O3=1:1, whereas in the case of the compound with a ratio MnO2:Cr2O3=2:1 peak for Mn3O4 only is observable without any trace for Cr2O3 on the diffraction chart. Furthermore in the compound of Fe2O3 and Cr2O3 the peak for Cr2O3 has been determined, but no peak for Fe2O3 can be found. 5. The x-ray diffraction analysis has also presented that in inclusions in steel and complex oxides extracted by using 10% Br-Methanol the inclusions give peaks for Cr2O3 only, and peaks for Mn3O4 and Cr2O3 are obtainable. Based on this observation only when inclusions in steel are extacted by using 10% Br-Methanol amorphous structure is formed by Br, but crystalline oxides are thought to be unchanged to the amorphous.
