The purpose of the present study is to identify the mediation effect of hope between fatigue and psychosocial adjustment in women with breast cancer. The framework for this study was guided by concepts and propositions derived from the theoretical and empirical literature on fatigue, hope and adjustment. The design of this study is a descriptive correlation study using a cross-sectional design. One hundred and twenty two outpatients with early breast cancer, receiving post-surgical radiation therapy or chemotherapy, were selected from three major medical centers in Seoul, Korea. A packet including PABCF (Psychosoical Adjustment to Breast Cancer Factor), revised RPFS (Revised Piper Fatigue Scale), HHI (Herth Hope Index), and self-addressed return envelope was given to the participants at seven to eight weeks post surgery. The questionnaires were to be completed at home and returned to the researcher by mail. The obtained data were analyzed using three regression equations guided by Baron and Kenny (1986); first, hope was regressed on fatigue; second, psychosocial adjustment was regressed on fatigue; and third, psychosocial adjustment was regressed on fatigue and hope, simultaneously. In the first equation, fatigue explained 4% of the variance in hope. In the second equation, fatigue explained 47% of the variance in psychosocial adjustment. In the last equation, hope and fatigue significantly explained the variance in psychosocial adjustment. Therefore, all conditions for the test of mediation effect of hope were satisfied. For the test of the mediation effect, the beta coefficients of fatigue on psychosocial adjustment on the second and third regression equations were compared. The beta coefficients were decreased from .69 (p < .001) on the second regression equation to .63 (p < .001) on the third regression equation. Thus, the hypothesis of this study was supported. As a result of this study, the negative Influence of fatigue on psychosocial adjustment is dampened through the mediator effect of hope in women with breast cancer. Therefore, when planning care for the adverse effect of fatigue on psychosocial adjustment, oncology nurses should consider hope as a mediator between fatigue and psychosocial adjustment to breast cancer.

Purpose: The aim of this study was to analyze the differences in psychosocial adjustment between younger (age${\leq}50$) and older (age>50) breast cancer survivors, and to explore the role of sociodemographic and disease-related variables in predicting psychosocial adjustment between younger and older breast cancer survivors. Methods: A total of 262 women participated in this study. A self-reported questionnaire, the Psychosocial Adjustment to Illness Scale-Self Report Korean version (PAIS-SR Korean version), was used. Data were analyzed with SAS/WIN 9.1 for descriptive statistics using the t-test, ANOVA, and stepwise multiple regression. Results: The psychosocial adjustment score of younger breast cancer survivors was significantly higher than that of older breast cancer survivors. Significant predictors influencing psychosocial adjustment in younger breast cancer survivors were marital state, menopausal cause, immune therapy, and self-help group, and these predictors account for 48% of the variance in psychosocial adjustment. Significant predictors influencing psychosocial adjustment in older breast cancer survivors were stage of cancer, monthly income, marital state, and menopausal cause. These predictors accounted for 35% of the variance in psychosocial adjustment. Conclusion: The findings indicate the importance of counseling and educational programs to improve the psychosocial adjustment according to breast cancer survivors' age.

The purpose of this study is to identify the characteristics of school life and to examine the influencing factors of academic adjustment and social adjustment in university students. This cross-sectional descriptive study by using secondary data from 2,064 subjects who responded to a self-rated student adjustment test. Descriptive, t-test, ANOVA, Pearson correlation and multiple regression analyses were conducted. Satisfaction with college selection, expectation for college, satisfaction with college service, emotional stability, and relationships with faculty were significantly higher among male students, whereas confidence in major, support from others were significantly higher among the female students. There was a significant positive relationship between academic adjustment and confidence in major, and between social adjustment and expectation for college. Confidence in major, relationships with faculty, emotional stability, expectation for college, satisfaction with college selection, and commitment to college life accounted for 31.8% of the variance in academic adjustment. In addition expectation for college, emotional stability, support from others, gender, commitment to college life, and satisfaction with college services accounted for 44.7% of the variance in social adjustment for university students. Overall, the results of this study suggest that understanding the levels of expectation for college, commitment to college life, and levels of emotional stability may be important for facilitating their transition and adjustment to university life.

The process controller in the adjustment procedure is often used effectively to control the process level close to target when noise is present and unremovable. Examples of the robust controller are single EWMA controller and double EWMA controller. Double EWMA controller is designed to reduce the offset of the process deviation, which single EWMA can not eliminate. In this paper, the two controllers are modified by taking EWMA of the original controller to reduce the adjustment variance, which may become excessively large when the two given controllers are implemented. It is shown that the EWMA modification of the given controllers is successful in reducing the adjustment variance, while the mean squared deviation increases slightly.

Purpose: The purpose of this study was to investigate psychological capital, sense of community and stress in relation to school adjustment and to identify factors influencing school adjustment in middle school students. Methods: This study population consisted of 150 middle school students. Data were analyzed using t-test, analysis of variance, Pearson correlation coefficient, and multiple regression analysis. Results: The mean score for school adjustment in middle school students was 3.68 out of 5 points. School adjustment explained 34% of the variance in sense of community (${\beta}=.39$, p<.001), positive psychological capital (${\beta}=.35$, p<.001), academic performance (${\beta}=.26$, p<.001), and stress (${\beta}=-.21$, p<.001). Conclusion: The results of our research suggest that sense of community is an important variable influencing school adjustment in middle school students. Therefore, to promote school adjustment in middle school students, it is necessary to develop and implement active educational strategies promoting sense of community, positive psychological capital, academic perfomance, and controlling stress.
