For the purpose of evaluating the effect of both direct retainer design and bony absorption degree around abutment of indirect retainer on the supporting tissue of abutment of indirect retainer, dislodging force was transmitted to unilateral distal extension RPD bases. Analysis of stress distributed within the supporting tissue around abutment of indirect retainer was carried out. Using three-dimensional photoelastic stress analysis method and the conclusion is a follows. 1. According to the extent of force which the direct retainer of the most distal abutment tooth, the amount of force transmitted to the abutment tooth of indirect retainer was small. 2. Of all the cases, Mandibular first premolar which was used abutment tooth of indirect retainer, buccal, mesial and distal sides represented compression stress and lingual side represented tensile stress. 3. The more bone resorption of abutment tooth of indirect retainer, the more distortion of buccal and distal side of abutment tooth was existed and the extent of compression stress which was existed and distal side to abutment tooth was large. 4. When the alveolar bone around the abutment with indircet retainer is normal. The amount of force transmitted on abutment with indirect retainer was small in the order of Akers clasp, RPA clasp, RPI clasp. 5. When the alveolar bone around the abutment with indirect retainer has been absorbed 20% and 30%, the amount of force transmitted on abutment with indirect retainer was small in the order of RPA calsp, RPI clasp, Akers clasp. 6.

This study examines the effect of satisfaction with adolescent extracurricular activities on social withdrawal with a focus on the mediating effect of self-esteem and sense of community. We used data from the 3rd wave (2012) of the Korean Children and Youth Panel Survey (KCYPS) collected by the National Youth Policy Institute for path analysis. Participants were 1,139 first year middle school students who participated in adolescent extracurricular activities. First, the degree of satisfaction with the adolescent extracurricular activities had an indirect effect on social withdrawal via self-esteem. Second, satisfaction with the adolescent extracurricular activities had an indirect effect on social withdrawal via a sense of community. Lastly, satisfaction with adolescent extracurricular activities had an indirect effect on social withdrawal via self-esteem and a sense of community. The research findings indicate that the level of social withdrawal is less when adolescents are satisfied with adolescent extracurricular activities and have a high level of self-esteem and sense of community. The results demonstrate that a satisfactory level of adolescent extracurricular activity would help adolescents decrease their social withdrawal by increasing the level of self-esteem and sense of community.

The effects of casting processes-direct and indirect squeeze casting, permanent mold casting and die casting on the microstructure and mechanical properties were studied for the hypereutectic B390 aluminium alloy. The effects of T5 and T6 heat treatment were also examined. The direct and indirect squeeze casting showed no casting defects such as porosity and shrinkage were observed in permanent mold castings and die castings. The primary silicon phase was refined and homogeneously distributed in the order of indirect squeeze casting, diecasting, direct squeeze casting and permanent mold casting. Depletion of primary silicon phase in die casting surface was disappeared in indirect squeeze casting. Tensile strength of cast and heat treated specimens were increased in the order of direct squeeze casting, permanent mold casting, indirect squeeze casting and die casting. Hardness of indirect squeeze castings was larger than that of other castings. As indirect squeeze casting of B390 aluminium alloy, the time of T6 heat treatment to achieve high strength can be reduced.
