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.

The recent domestic violence research has emphasized an integrated approach to wife battering and child abuse to overcome separated understanding and problem-solving alternatives of the two phenomena in the past. This phenomenological study is designed to understand struggles and dilemmas of battered women and their children related to their surviving and coping with domestic violence in a mother-child relationship. In-depth interviews were conducted with ten battered women who have children and reside in shelters in Seoul and Anyang, and were analyzed by Atlas.ti(a qualitative software program) to maximize the efficiency of data analysis. Domestic violence can be transformed into and integrated with child abuse anytime, so battered women and their children share their crises and challenges related to motherliness and filial love. However, the mutual, existential meaning embedded in the mother-child relationship can be the most important sources to mobilize their life energy and resilience in their copping efforts. The social work interventions for battered women and their children should be integrated with a premise of deep understanding of the complex realities of domestic violence victims.

The raw surf clam meat was pretreated with BHA, EDTA or $NaHSO_3$. The pretreated meat was chopped with chopper, and spread the chopped meat on nylon net, and then dehydrated with cabinet type hot air dryer. In the surf clam meat flake process, the pretreating and the copping steps prior to final dehydration improved the pigment retention and texture of the products. The chopping steps prior to dehydration reduced the dehydration time of surf clam meat. The BHA treatment prior to dehydration of mashed surf clam meat had an outstanding effect on the pigment retention during a process of dehydration and storage. The surf dam meat flakes reabsorbed water more rapidly about two times than the dehydrated natural surf clam meat products. The surf clam meat flakes stored for three months in the dark place showed less pigment loss than the exposed ones, and the former reabsorbed water more rapidly than the latter.
