For form stability of membrane structures, membrane material is required to be in tension. Therefore, in planning and maintenance management, the engineer should consider enough about introduction of stress during construction and re-introduction of stress after completion. Clamping part is an important portion with the function for introducing tension into membrane materials, and the function to transmit stress to boundary structures, such as steel frames. Then, the purpose of this research is to clarify stress condition and stress transfer mechanism including clamping part of membrane structures, and to grasp the changing tendency of membrane structures with the passage of time. In this research, following previous one, we perform well-balanced evaluation by conducting tensile fractured tests of clamping part's specimens, and by measuring individually the amount of displacement of not only overall specimen's length but membrane material and clamping part. Thereby, we consider the influence the difference in the hardness of edge rope and the difference in the direction of thread affect modification and fracture load.

Although there have been many studies on the risk factors for coronary artery disease, but there have been rare an attempt to examine the effect of risk factors on exercise test. The IJUI1Xlse of this study was to research the effects of training, stroking and drinking habit on results of treadmill exercise test. The subject of study was adult patient 5.l) cases be Questionable as coronary artery disease in Dept, of Cardiovascular Center, Kang Dong Sacred Heart Hospital between May 1ffi7 to February 1~. In this study used to rmdified Bruce protocoHCase 16, Marquette co``>. Total positive rate was ~.8%U44 cases) by treadmill exercise test, it was male higher than femalet 16.30/0: 14.6%), that was seen significantly differ as increase of age. As training habit, positive rate of nontraining group was higher than training group(18.4%:12.4%), have been no relationship both regularity and frequerey between nontraing and traning groups, but performance degree of workload level was high in training group. As stroking habit, positive rate of stroking group was higher than nonsmoking group in males(57.goA):42.1%), 9 cases of total ~ cases in females, there was have been high positive rate(45%). As drinking habit, positive rate of between drinking and nondrinking groups was no significantly differ, but positive rate of drinking group was a few higher than nondrinking group in male and female groups.
