The main purpose of this study was to examine pathways from interparental conflict to adolescents' problem behavior through maternal support and control and/or quality of peer relationship. A sample of 340 high school students (166 boys and 174 girls) in Incheon completed questionnaires on interparental conflict, maternal support and control, quality of peer relationship, and problem behavior. Data were analyzed by means of structural equation modeling. The results demonstrated that interparental conflict had a direct influence in both internalizing and externalizing problem behaviors, indicating that adolescents who perceived higher levels of interparental conflict had more problem behaviors. Regarding pathways from interparental conflict to problem behavior through maternal support and control and/or quality of peer relationships, adolescents perceiving higher levels of interparental conflict reported higher maternal psychological control and lower support and behavioral control. This was followed by a lower level of quality in terms of their peer relationships; the lower quality of peer relationships resulted in more adolescent problem behaviors. These results indicate that interparental conflict and maternal support and control play crucial roles in the development of internalizing and externalizing problem behavior, respectively.

This study examined the influence of family risk factors, ego-resilience, and quality of peer relationships on adolescent problem behaviors in a sample of 335 8th grade students (178 boys and 157 girls). They responded to four kinds of questionnaires. Data were analyzed by independent t-tests, correlations, and multiple regressions. Results showed that family risk factors had direct effects on ego-resilience which directly affected quality of peer relationships. Family risk factors, ego-resilience and quality of peer relationships had direct effects on internalizing problem behaviors. Family risk factors and quality of peer relationships had direct effects on externalizing problem behaviors. Family risk factors indirectly influenced adolescent internalizing/externalizing problem behaviors through ego-resilience and quality of peer relationships.

This study examined the relation between the quality of constructive play and convergent and divergent problem solving. The subjects were 48 five-year-old children. Unit blocks were used to test the quality level of constructive play; a 40 piece puzzle and pattern blocks were used to test convergent problem solving; the pattern blocks also were used to test divergent problem solving. Children's block play was videotaped and pictures were taken of constructions made by children. Data were analyzed by correlation and stepwise multiple regression. Results showed statistically significant correlations between the quality of constructive play and convergent and divergent problem solving. Among the sub variables of constructive play, social play patterns affected convergent problem solving; diversity affected divergent problem solving.

Background: This study investigated the utilization of both problem and emotion focused coping strategies and their association with aspects of quality of life among Turkish women with ovarian cancer undergoing chemotherapy. Materials and Methods: The convenience sample consisted of 228 patients in all disease stages. The data were collected using the brief COPE, QOL-Cancer patient tool, sociodemographic sheet, and medical variables were gathered from patients' medical charts. Results: Findings reveal that quality of life is moderately high for this group of cancer patients, despite some specific negative facets of the illness and treatment experience. Acceptance, emotional support and religion were the most frequently used problem-focused coping strategies and self-distraction, venting and behavioral disengagement were the most frequently used emotion-focused coping strategies reported by patients. Overall quality of life and, particularly, psychological and spiritual well-being scores of younger patients were lower. Patients reported using significantly more problem-focused coping than emotion-focused coping, and more problem-focused and less emotion-focused coping predicted greater quality of life. Problem-focused coping was related to patients' physical and spiritual well-being and emotion-focused coping was related inversely with psychological and social well-being. Conclusions: Coping strategies are influential in patient quality of life and their psychosocial adaptation to ovarian cancer. Psycho-oncology support programs are needed to help patients to frequent use of problem-focused coping and reduce emotion-focused coping strategies to improve overall quality of life.

This Research was designed to develop an instrument that can be used for measuring and analysing the degree of the quality of life of the Allogenic bone marrow transplantation survivors and to provide basic data to help them attain a better quality of life. The subjects of this study were a total of 101 people who were undergone Allogenic bone marrow transplantation and were over 100 days after transplantation. Data were collected during the period from September 3 to December 2. 2000. In Developing this instrument, the researcher established a conceptual framework based on the result of previous research, interview of patients and medical staff and researcher's experience. The scale for this instrument consisted of 51 items. Responses were obtained from the respondents through a self reporting method and each item had a possible score of 5. The collected data were analyzed using the SPSS program. The reliability of the scale was tested by Cronbach‘s alpha. For the examination of the component factors of the measuring instruments, factor analysis method was used. Examination of the difference in the quality of life as related to demographic variables was done using t-test, analysis of variance(ANOVA). For the examination of the major variables influencing the quality of life, Pearson's Correlations was used. The results were as follows: (1) The reliability of the instrument was 0.90 (Cronbach's alpha) (2) The validity of the instrument was tested by factor analysis. The result of the factor analysis of the 51 items is making up the instruments were classified into the following factor; emotional state, Interpersonal problem, physical problem, spiritual state, social problem, decrease of physical energy, physical problem-eye, physical problem-skin and mucosa, health awareness, elimination problem, worry about health, financial problem, sexual problem. (3) Demographic variables related to quality of life is the time after transplantation. GVHD experience, lose of job. Age at the transplantation, diagnosis, type of the transplantation, marital status, monthly income, educational background, sex, religion are not related to the quality of life.

The problem of brake judder is typically caused by quality defects in manufacturing. This quality problem, however, can't be controlled deterministically and requires analyses and designs considering uncertainties. This paper presents a method for dynamic analysis of a brake judder considering uncertainties. Firstly, quality defects, which come from the uncertainties, are determined by examination of symptoms of the brake judder quality problem. Effective quality defects are selected by investigation of process capability and comparison of sensitivity of each quality defects and noise levels of the effective quality defects are determined. Secondly, flexible multibody dynamic analysis and finite element analysis according to the proposed method are carried out. Finally, The analysis results are compared with the test results with noise levels of the effective quality defects.
