A Study on the Fracture Strength of All-Ceramic Crown according to the Zirconia Coping Design using CAD/CAM System L. Bulgan, In-Ho Cho, Soo-Yeon Shin Department of Prosthodontics, Graduate School, Dankook University The fracture strength of prosthesis is important, because it affects the function, and long term success of prosthesis and teeth. The purpose of this study was to compare the fracture strength of zirconia coping designs. Experimental test group were classified into three designs according to coping design, Modified design: Zirconia coping margin was located at 1mm above the axiogingival line angle. Collarless design: The coping margin terminated at the axiogingival line angle Butt design: The coping margin was extended to the finishing line of prepared margin. A $Cercon^{(R)}$(Degussa, Germany) CAD/CAM system was used to make the zirconia coping. Fracture strength was measured using loading machine at a cross head speed of 1mm/min. The results were statistically analyzed using the one-way ANOVA and multiple comparison test. Statistical significance was set in advance at the probability level of less than 0.05. The result : I. Collarless($738N{\pm}155N$) and Modified($755N{\pm}185N$) groups showed significantly a lower fracture strength than Butt($1057N{\pm}262N$) group(p<0.05). II. There were no statistical differences of the fracture strength between Modified($755N{\pm}185N$) and Collarless($738N{\pm}155N$) groups. III. When comparing the fractured surface, all the group showed porcelain fracture, which were fractured at the labial surface of baked porcelain The butt design of the zirconia coping has higher fracture strength than modified and collarless design.
Objectives: The purpose of the study is to investigate the influence of social characteristics and self leadership on stress coping method in the dental hygiene students.

The purposes of this study are to identify stress and coping strategies of married working women. Data were collected from 185 married working women, living in the metropolitan area. The results were as follows: 1. Low family function and high occupational stress affected stress symptoms of married working women significantly, but type A personality was not related to the stress symptoms. 2. The more the married working women perceived stress symptoms, the more they utilized organizational coping strategies. 3. The women who used personal coping strategies effectively also used more effective organizational coping strategies. 4. Two paths were statistically significant : family function$\rightarrow$stress symptoms, occupational stress$\rightarrow$stress symptoms. But the others were not. Based on those results, the model was modified by adding four paths : A type personality$\rightarrow$personal coping strategies, occupational stress$\rightarrow$organizational coping strategies, personal coping strategies$\rightarrow$organizational coping strategies, organizational coping strategies$\rightarrow$stress symptoms. 5. The modified model produced a better fit than hypothetical model(GFI=0.9985, ACFI=0.9893, NFI=0.9920, NNFI=1.1330, RMSR=0.0030, PNFI=0.1984). In conclusion, the stress management for married working women needs to focus on both organizational coping strategies and personal coping strategies.

Findings were that 14% of the children were bullies, 14% were victims, and 11% were bully/victims(bullies in one situation and victims in a different situation). Sex differences showed that boys who are victims and bully/victims used more passive coping than bully type boys. Bully and bully/victim types used more aggressive coping; victim types used more evasive coping. For girls, bully and bully/victim types used more passive coping than the victim types, who used more evasive coping. Bully types used more social support-seeking in their coping than victims and bully/victim types.

The data were collected by a survey of convenience sampling of 257 cancer patients and 196 of their caregivers from two hospitals in Seoul. The data were analyzed using paired t-test, unpaired t-test. Result: The stress level of cancer patients was lower than their caregivers. The cancer patients used emotion-focused coping mode than problem-focused coping mode. The caregivers problem-focused coping mode over emotion-focused coping mode. In the problem-focused coping mode, the caregivers significantly used two coping strategies that were ‘positve cope’, ‘information seeking’ more than patients. In emotion-focused coping mode, the caregivers significantly used one coping strategies that was ‘wish’ more than patients. The patients tended to used two coping strategies that were ‘blame’ and ‘emotion expression’ more than the caregivers.
