Purpose: This cross-sectional study was carried out to identify factors influencing the health-related quality of life according to socioeconomic level during early adolescence. Methods: Participants were 617 middle school students in $1^{st}$ and $2^{nd}$ grade. All measures were self-administered. Data were analyzed using SPSS 21.0 program and factors affecting the health-related quality of life were analyzed by t-test, ANOVA, Duncan test, Pearson's correlation coefficient, and multiple regression analysis. Results: According to the level of Family Affluence Scale (FAS), 19.1% of the participants were in the high class, 66.5% in the middle class, and 14.4% in the low class. We have found statistically significant differences among the high, middle, and low classes regarding the health-related quality of life, health perception, resourcefulness, family function, and social capital. The most influential factors of the health-related quality of life were found to be resourcefulness, family function, and social capital in the high and the middle class. Conclusion: The implication of this study is that it is important for the Education Ministry and middle school teachers to help adolescents develop internal coping resources as well as to develop school-curriculums considering social values and norms related to social capital in order to improving their health-related quality of life.

This study is aimed to discover the deciding factors in senior employment programs for improving the quality of life for the elderly. The dependent variable used in this study was the quality of elderly persons. Personal and familial characteristics, and the community involvement of the elderly were used as independent variables in a Multiple Regression analysis. First, the most influential factor encouraging the elderly to participate in a senior employment promotion program was previous experience of senior employment programs. Second, health condition, residence in city areas, experience of volunteer work, and knowledge of senior employment programs had positive effects on the continuous participation of the elderly men and women. However, living arrangements had an effect solely on elderly men, and home ownership and participation in economic activities had effects solely on elderly women. Third, the life quality of the elderly was affected differently by sex. Health condition had the greatest effect on male elderly persons, whereas, the effective variable, the composition of the family had the most effect on female elderly persons. Thus, active campaigns through various mass media and information sessions are needed to promote participation in senior employment programs, according to the above mentioned deciding factors. In particular infrastructure providing the elderly with more volunteer work opportunity needs to be built for baby boomers to improve their quality of life. In addition, diversified senior employment programs are needed. Because the elderly living in city areas are more willing to participate in senior employment programs, specialized programs suitable for the elderly in city areas are needed. The government should also prepare programs that help the elderly stay healthy while they are working.

Purpose: This study was a descriptive survey research to identify the impact of bowel function, anxiety and depression on quality of life in patients with rectal cancer who had a sphincter-preserving resection. Methods: Participants were 100 patients who had rectal cancer surgery at W hospital in Korea. Bowel function, anxiety & depression, and quality of life were measured using the BFI (Bowel Function Instrument), HADS (Hospital Anxiety-Depression Scale) and the FACT-C (Functional Assessment of Cancer Therapy-Colorectal). Results: The mean scores were $39.81{\pm}5.16$ for bowel function, $6.15{\pm}3.25$ for anxiety, $7.24{\pm}3.13$ for depression, and $72.50{\pm}13.27$ for quality of life. There were significant negative correlations between quality of life and anxiety (r= -.59, p <.001) and between quality of life and depression (r= -.53, p <.001). But the correlation between quality of life and bowel function was significantly positive (r=.22, p =.025). The influence of the independent variables on the total quality of life was examined using multiple regression analysis. Anxiety (${\beta}$= -.38, p =.002), bowel function (${\beta}$= -.25, p =.028) and occupation (${\beta}$=.16, p =.048) were identified as factors affecting quality of life. The explanation power of this regression model was 44% and it was statistically significant (F=16.53, p <.001). Conclusion: The results of this study indicate that in order to improve the bowel function of patients after sphincter-preserving resection for rectal cancer, effective nursing interventions should be developed. As psychological problem such as anxiety and depression can relate to quality of life for these patients, nurses should work on improving the situation by providing continuous emotional nursing.

In this paper, the analytical fault detection and diagnosis (FDD) is presented using model-based and signal-based methodology with wavelet analysis on signals obtained from sensors and sensor networks. In the model-based FDD, we present the modeling of contact interface found in soft materials, including the biomedical contacts. Fingerprint analysis and signal-based FDD are also presented with an experimental framework consisting of a mechanical pneumatic system typically found in manufacturing automation. This diagnosis system focuses on the signal-based approach which employs multi-resolution wavelet decomposition of various sensor signals such as pressure, flow rate, etc., to determine leak configuration. Pattern recognition technique and analytical vectorized maps are developed to diagnose an unknown leakage based on the established FDD information using the affine mapping. Experimental studies and analysis are presented to illustrate the FDD methodology. Both model-based and wavelet-based FDD applied in contact interface and manufacturing automation have implication towards better quality of life by applying theory and practice to understand how effective diagnosis can be made using intelligent FDD. As an illustration, a model-based contact surface technology an benefit the diabetes with the detection of abnormal contact patterns that may result in ulceration if not detected and treated in time, thus, improving the quality of life of the patients. Ultimately, effective diagnosis using FDD with wavelet analysis, whether it is employed in biomedical applications or manufacturing automation, can have impacts on improving our quality of life.
