  • The purpose of this study is to find out the factors affacting liquefaction potential by using DSC(disturded state concept) method and to verify these results through cyclic shear test (truly triaxial test and cyclic triaxial) on saturated sandy soil. Based on this reserch, the DSC method predictions were found to provide satisfactory correlation with the cyclic shear test. And the relationship between the factors affecting liquefaction characteristics--relative density(Dr0 and initial effective confining pressure and physical properties of the saturated sand --ξD and Dc--is found. If the relative density and the initial effective confining pressure increase, the number of cyclic grows up. This means that Dc is incresed and ξD is decreased. Therefore, the liquefaction potential can be evaluated and the factors affacting liquefaction potential can be investigated by using on DSC method. Finally, it is shown that the DSC method can capture the liquefaction mechanism.

  • In this study, shearography and ESPI have been used for quantitative analysis of an inside crack of pipeline and both of them appeared suitable to qualitatively detect inside crack. However, shearography needs several effective factors including the amount of shearing, shearing direction and induced load for the quantitative evaluation of the inside crack. In this study, the factors were optimized for the quantitative analysis and the site of cracks has been determined. Although the effective factors in shearography has been optimized, it is difficult to determine the factors exactly because they are related to the details of tracks. On the other hand, ESPI is independent on the details of a crack and only the induced load plays an important role. The out-of-plane displacement was measured under the optimized load and the measured were numerically differentiated, which resulted in an equivalent to the shearogram. The size of cracks can be determined quantitatively without any detail of a crack.

  • Responses from the information users on the information technology are very important considerations when majority of the companies are going to introduce information technology by way of computers. When new information technology is introduced, resistance from the information users are likely to be happen and if suitable management about this is not carried out, resistance from the users of information technology will be continued. It is needed for the companies to minimize user's resistance about the information technology to reduce the introduction cost of information technology and to elevate the degree of use. To reduce the resistance from the users about information technology, factors which affect the resistance of users should be analyzed first and it will be effective to control those factors later on. Therefore it will be meaningful for the successful management of information technology if several factors which affect the resistance of users about information technology are searched out and managed. The purpose of this study is to find various factors which affect the resistance of the individuals in the organization about information technology in the process of introducing information technology. The relationship between the factors and factors which affect indirectly to the information technology are the things which are supposed to be considered to the companies who are going to introduce information technology in the long run. Instead of decreasing the resistance directly, let individuals in the organization decreases the resistance by themselves is a more effective way and may have less side effects, in terms of controlling the members in the organization.

  • Purpose: This study is aimed at testing the effect of health promotion program on health promoting behavior and cardiovascular risk factors of middle-aged women. Method: The research design was the nonequivalent control group pre-post test. Twelve middle-aged women were the experimental group and ten were the control group. The 8-week health promotion program was given to the experimental group. There were health promotion theories, flexibility and muscle strength exercise, cardiopulmonary endurance exercise, nutrition, stress management, cancer prevention and early detection, management of menopause and wrap-up in health promotion program for middle-aged women. The measurement tool was Health Promoting Behavior developed by researcher using serum cholesterol, obesity rate, systolic blood pressure, and diastolic blood pressure as cardiovascular risk factors. Result: The experimental group showed a higher score of health promoting behavior than the control group. There were no differences on cardiovascular risk factors(cholesterol, obesity rate, diastolic blood pressure) between the experimental and control groups except systolic blood pressure. Conclusion: Conclusively, this health promotion program for middle-aged women was effective in increasing health promotion behaviors, but wasn't effective in decreasing cardiovascular risk factors except the systolic blood pressure. It seems it's necessary to re-study this using more samples and a longer duration of the program, and smaller mortality rate.

  • Tunnel excavation in shallow soft ground conditions of urban areas experiences inevitable surface settlements that threaten the stability of nearby infrastructures. Surface settlements during shield TBM tunneling are related to a number of factors including geotechnical conditions, tunnel geometry and excavation methods. In this paper, a database collected from a construction section of Hong Kong subway was used to analyze the correlation of settlement-inducing factors and surface settlements monitored at different locations of a transverse trough. The Pearson correlation analysis result revealed a correlation between the factors in consideration. Factors such as the face pressure, advance speed, thrust force, cutter torque, twin tunnel distance and ground water level presented a modest correlation with the surface settlement, while no significant trends between the other factors and the surface settlements were observed. It can be concluded that an integrated effect of the settlement-inducing factors should be related to the magnitude of surface settlements.

  • The purpose of this study is to evaluate visual preferences of the methods for river embankment based on seasonal changes and to reveal the relationship between visual preference and effective factors, which are the physical and esthetic elements inside the river. For this research seven river embankment methods including concrete block, concrete wall, gabion, and vegetated concrete block were selected in Dongchon of Gwangyang. Twenty-eight pictures by the four pictures of each embankment method based on seasonal changes, the winter and summer of the first and second years after construction were used for a photo-questionnaire by 49 participants. In the analysis of the relationship between visual preference and effective factors, the independent variables included eight factors: form of the material, harmony with the surroundings, the cleanness of river floor, the green area of embankment methods, the water area in river floor, the stone and sand area in river floor, the planting area in river floor, and the area of embankment itself. The result of this study are as follows. First, visual preference in summer was higher than in winter, and the summer landscape of the second you scored the highest value for visual preference. Second, similarly to the way the vegetated concrete block produced a green effect, cobblestone and gabion embankments made of natural materials scored higher than others, whereas the concrete retaining wall scored the lowest of all methods because of it's artificiality. Third, the seven independent variables, except form of the material, are proved statistically significant at the 5% level. The water area in river floor, harmony with the surroundings, the planting area in river floor, and the cleanness of the river floor were revealed as more effective factors influencing visual preference. The research results suggest that the riverscape has to be controlled in terms of seasonal change and embankment methods. Natural materials and green effects in embankment methods are more important for increasing landscape preference, and the landscape factors inside a river should also be considered important variables. It is recommended that advanced study on other factors affecting visual preference of the riverscape be carried out to support this research.
