In this paper, a covariate adjusted logrank test is considered for censored paired data under the Cox proportional hazard model. The proposed score test resembles the adjusted logrank test of Tsiatis, Rosner and Tritchler (1985), which is derived from the partial likelihood. The dependence structure for paired data is accommodated into the test statistic by using' sum of square type' variance estimators. Several weight functions are also considered, which produce a class of covariate adjusted weighted logrank tests. Asymptotic normality of the proposed test is established and simulation studies with moderate sample size show the proposed test works well, particularly when there are dependence structure between treatment and covariates.

Purpose: This study was done to identify degrees of factors influencing parenting self-efficacy in grandmother raising infant and toddler. Method: A convenience sample of 121 grandmothers whose grandchild was between 3 to 36 months old was used. The variables were health status, health problems and life event. The data were collected through a questionnaire survey and descriptive statistics, t-test, ANOVA with Scheffe test, Pearson correlation coefficients and stepwise multiple regression were used to analyze using SPSS WIN 12.0. Results: The average score for parenting self-efficacy was 39.39(SD=5.09), somewhat higher than moderate in level. Factor that was significant in influencing parenting self-efficacy was life event. This factors accounted for 14.6% of explained variance. Conclusions: It was found that the life event was influenced to parenting self-efficacy in grandmothers raising infant and toddler. From this study it is proposed that there is a need to develop programs and policies which support them. Ultimately a good care environment for children will be good for the young children's growth and development.

This study explored the perceptions of Korean college women concerning their clothing deprivation and clothing decision factors. A convenience sample was used consisting of 101 female college students aged from 18 to 36 years, with a mean age of 20.78 (SD = 4.24). Descriptive statistics were used to develop a profile of the participants. To test the research objectives, multivariate analysis of variance (MANOVA), using Wilk's lambda criterion was conducted for the study. The results indicated that a college woman's year significantly influences her perceived clothing deprivation, at p =0.003 (Wilk's lambda). There was a significant positive correlation (r = 0.24, p= 0.02) between college year and perceived clothing deprivation for special occasion clothes. The two clothing decision factors clothes that fit me well and clothes that look best on me were found to be the top two factors determining clothing decisions for the study participants.

In this study, we propose several simultaneous tests to detect the difference between means and variances for the two-sample problem when the underlying distribution is normal. For this, we apply the likelihood ratio principle and propose a likelihood ratio test. We then consider a union-intersection test after identifying the likelihood statistic, a product of two individual likelihood statistics, to test the individual sub-null hypotheses. By noting that the union-intersection test can be considered a simultaneous test with combination function, also we propose simultaneous tests with combination functions to combine individual tests for each sub-null hypothesis. We apply the permutation principle to obtain the null distributions. We then provide an example to illustrate our proposed procedure and compare the efficiency among the proposed tests through a simulation study. We discuss some interesting features related to the simultaneous test as concluding remarks. Finally we show the expression of the likelihood ratio statistic with a product of two individual likelihood ratio statistics.

Purpose: The goals of this study were to identify the relationships among learning agility, grit, positive psychological capital, and nursing performance and to determine the impact of these factors on clinical nursing performance. Methods: Between November and December 2021, a descriptive survey design was conducted with a convenience sample of 260 clinical nurse participants from two regional hospitals. Data were collected using the Learning Agility Scale, Grit Scale, Psychological Capital Questionnaire, and the Nursing Performance Scale. Data from 248 nurses were analyzed using descriptive statistics, independent t-test, one-way analysis of variance, Pearson's correlation, and multiple linear regression analysis using SPSS 27.0. Results: Results revealed significant positive correlations between nursing performance and learning agility, grit, and positive psychological capital. Stepwise multiple regression analysis identified positive psychological capital as the strongest predictor of nursing performance, followed by work experience, learning agility, grit, and educational level. These variables accounted for 51% of the variance in nursing performance. Conclusion: This study underscored the importance of positive psychological capital, learning agility, and grit in improving nursing performance. Healthcare organizations should prioritize the development of these attributes among nurses. Implementing strategies to enhance these factors in nursing practice and education could improve nursing performance, potentially resulting in better patient outcomes and increased job satisfaction. Future research should explore specific interventions to cultivate these qualities and assess their long-term impact on nursing practice.

Purpose: The purpose of this study was to identify the relationships between physical activity, health status, and quality of life (QOL) of University students. Methods: The research design was based on a descriptive research design model. This study sample consisted of 183 K University students in D city. Data was collected from December 2012 to January 2013 and analyzed with descriptive statistics (frequency, percentage, analysis of variance (ANOVA), t-test, and Pearson's correlation analysis) using SPSS 19.0. Subjects completed questionnaires on their demographics, physical activity, health status, and QOL. Results: The overall physical activity of participants was $2529.40{\pm}5057.896$ min/week on average. The average health status was $28.66{\pm}6.3$ and the average physical health and mental health were $16.45{\pm}3.955$ and $12.31{\pm}3.446$, respectively. The overall degree of QOL was $3.429{\pm}0.379$. A positive relationship existed between moderate and vigorous activity and health status. In addition, QOL positively correlated with physical health (under health status). However, physical activity was not related with both mental health (under health status) and QOL. Conclusion: Based on the results of this study, health educational programs are needed to promote sufficient physical activity in university students.
