The main aim of this study was to evaluate the bending and torsional behaviors of representative regular type cap beams in elevated guideway structures. A1/2 scale model copping beam, excluding the column portion, was designed, constructed, and tested. The copping beam was subjected to horizontal monotonic and cyclic loads with a constant vertical load over the loading stage. The damage was very much dominated by torsion. Experiment results showed that the spiral confinement in the beam helped to restrain the opening of torsional cracks in the column zone. Hence, the torsional strength of the cap beam contributesgreatly to the confinement conditions of the column.

This is a section study for research of main cause and coping ways caused by stresses during the clinical experiment. It was researched by 231 students of third grade have finished clinical experiment until September though questionnaire. The methods for this study used the a stress measuring instrument thai was used by Hoa-Yun Jun and coping ways of stresses devised by Bell. We computed the frequency and the mean value by the SPSS 10.0 statistical data and we got the following result that from the experiment with t-test and the ANOVA analysis. 1. The mean value of stresses indicated rather higher states in figures 2,855 and the figures that were classified by each areas, indicated highest figures are affected by circumstances, that is 3.065. 2. As higher as the degree of satisfactions in their major, students feel stress less so, the result was not quite different between each of them (p=0.007). 3. The copping ways of stresses indicated, similar differences by using of long-term copping ways and short-term copping ways to cope with stresses(p=0.000). 4. In case of the students who failed college entrance exams and prepared for the next chance for more than one year, indicated highest figures that is 2.57 in short-term ways to cope with stresses, so it showed slightly differences between them(p=0.014). 5. According to the satisfactions of clinical experiments, there were not any statistical differences in long-term coping ways but, as smaller as the satisfactions, in that evidence of the students use short-term copping ways, it showed slightly differences between them(p=0.041). 6. According to the degree of stresses, low-stress groups use short-term coping ways more than high-stress groups, so it showed slightly differences between them(p=0.001). 7. As far as the using of long-term coping ways, the figures of between the lower stress groups and the higher stress groups indicated 2.89 and 2.97 respectably so, the figures were not so closed.

The purpose of this study is to evaluate the color differences in the In-Ceram according to coping thickness and various abutment core materials ; amalgam, precious alloy, composite resin, non-precious alloy. After the porcelain was built up on the In-Ceram coping at the thicknes of 0.3mm and 0.5mm then it was cemented with glass ionomer cement to the post & core materials. The following results were obtained. 1. There were significant differences in the $L^*$ values $a^*$ and $b^*$ values in the cementation of different cores, to the In-Ceram(P<0.01). $L^*$ values were not significantly different between the composite resin to the In-Ceram and the $a^*\;b^*$ values were not significantly different between the amalgam and the non-precious alloy. 2. All of cementations of In-Ceram to the core materisal had color difference(${\Delta}E^*ab$) compared to the In-Ceram. In the 0.3mm thickness of the In-Ceram copping non-precious alloy indicated the greatest value, while the composite resin core showed the lowest value with a thickness of 0.5mm In-Ceram copping. 3. By controlloing the In-Ceram coping thickness $L^*$ value was significatly different(P<0.01), but not in $a^*$ and $b^*$ values. 4. In an amalgam, precious & non-prcious alloys there was a 1,74 to 3.06 range color difference in the controlled thickness of In-Ceram coping at the thickness of 0.3mm and 0.5mm. The above results suggest that the requirement of the sufficient thickness of In-Ceram coping and the suitable core material in order to get an estheti restoration by In-Ceram and also to intercept the original core color.

Purpose: This study was to describe the process of healthy dieting and develop a substantive theory that explains lifestyle in obese male college students. Methods: The participants were 11 students who had participated in self-dieting program in a health center. Data were collected with in-depth interviews and analyzed by grounded theory in Strauss and Corbin (1990). Results: Through analyzing process, 36 concepts, 18 subcategories, and nine categories were deduced. In axial coding, casual condition, 'shrinking themselves' and 'oriented to selfish lifestyle', context condition, 'distress in mutual understanding' impacted on phenomenon, 'making health with autonomous living pattern'. Intervening conditions were 'practicing with active measures' and 'growing the willpower' and action-interaction condition, 'devoting realistic plan with positiveness' totally lead to consequence in 'regaining social relationship' and 'pursuing harmonious sound of mind and body'. The periods of process were divided four stages, reflecting self-characteristics, situational copping phase, applying period realistic strategies, and developing phase of social relationship. The core category, 'developing communication competency' incorporated the relationship between and among all categories and explained the process. Conclusion: The findings indicate that self leading health program helped to develop the communication competency. Therefore, we would consider about internalized motives and external incentives in health programs.
