The present study aimed to investigate the effects of maternal factors on body weight at hatching (day-old) and at six weeks of age in a commercial broiler line. A total of 6,765 records on body weight at day-old (BWTDO) and 115,421 records on body weight at six weeks of age (BWT6W), originated from a commercial broiler line during 14 generations, were used to estimate genetic parameters related to the effects of maternal traits on body weight of chicks immediately after hatch or six weeks thereafter. The data were analyzed using restricted maximum likelihood procedure (REML) and an animal model with DFREML software. Direct heritability ($h^{2}{_a}$), maternal heritability ($h^{2}{_m}$), and maternal environmental variance as the proportions of phenotypic variance ($c^{2}$) for body weight at day-old were estimated to be 0.050, 0.351, and 0.173, respectively. The respective estimated values for body weight at six weeks of age were 0.340, 0.022, and 0.030. The correlation coefficient between direct and maternal genetic effects for six-week-old body weight was found to be -0.335. Covariance components and genetic correlations were estimated using a bivariate analysis based on the best model determined by a univariate analysis. Between weights at hatching and at six week-old, the values of -0.07, 0.53 and 0.47 were found for the direct additive genetic variance, maternal additive genetic variance and permanent maternal environmental variance, respectively. The estimated correlation between direct additive genetic effect influencing weight at hatch and direct additive maternal effect affecting weight at six weeks of age was -0.21, whereas the correlation value of 0.15 was estimated between direct additive maternal effect influencing weight at hatch and direct additive genetic effect affecting weight at six-week-old. From the present findings, it can be concluded that the maternal additive genetic effect observed for weight at six weeks of age might be a factor transferred from genes influencing weight at hatch to weight at six-week-old.

This study was conducted to examine the mediating effects of social anxiety and academic self-efficacy in the relationship between adolescent covert narcissism and school life adaptation. The subjects were 423 middle school and high school students. The results of this study are as follows: First, covert narcissistic personality tendency had a negative correlation with school life adaptation(r=-.51, p<.01). Covert narcissism had significant positive correlation with social anxiety(r=.70, p<.01) but had negative correlation with academic self-efficacy(r=-.39, p<.01). Social anxiety showed a significant negative correlation with school life adaptation(r=-.50, p<.01), academic self-efficacy had a positive correlation with school life adaptation(r=.63, p<.01), and social anxiety had a negative correlation with academic self-efficacy(r=-.51, p<.01). Second, as a result of verifying the mediating effects of social anxiety and academic self-efficacy, academic self-efficacy has mediating effects on the relationship between covert narcissism and school life adaptation(${\beta}=.41$, p<.001), and social anxiety has no mediating effect on school life adaptation(${\beta}=-.05$, p<.001). The results of this study suggest that If adolescents with covert narcissism have difficulties in adapting to school life, increasing academic self-efficacy, especially self-control efficacy and self-confidence, may be helpful to improve adolescents' adaptation to school life.

Purpose : The purpose of this study is to identify the degree of occupational therapist's professional ethics and to examine the correlation between professional ethics, job stress, and burnout. It also investigates the effects of the occupational therapist's professional ethics on job stress, and burn out, so that we can find a way to reduce them in occupational therapists. Methods : We conducted surveys from June 1 to July 5, 2022. The general characteristics were examined using a frequency analysis. Professional ethics, job stress, and burn out were examined using descriptive statistics. The correlation among them was analyzed with the Pearson correlation coefficient. To find out what factors affect job stress and burn out, we also conducted a multiple regression analysis. Results : First, professional ethics was averaged at 3.57±.34. Second, a significant negative correlation in professional ethics was found between job stress and burn out (p<.01). As a result of the correlation between occupational ethics sub-factors and job stress and burnout, factors excluding nonleisure and self-reliance showed a statistically significant correlation (p<.01, p<.05). Third, professional ethics sub-factor was affected job stress and burn out (p<.01, p<.05). The sub-factors affecting job stress were hard work (𝛽=.-461, p<.01), delay of gratification (𝛽=.-267, p<.01), and relation with coworker (𝛽=.-245, p<.01) and morality (𝛽=.-165, p<.05); and those influencing burnout were delay of gratification (𝛽=-.240, p<.01), relation with coworker (𝛽=-.223, p<.01), centrality of work (𝛽=-.189, p<.01) and hard work (𝛽=-.184, p<.05). Conclusion : The results of this study confirmed the importance of professional ethics affecting job stress and burn out. Through follow-up research, it will be necessary to develop and apply programs to improve professional ethic of occupational therapists in the future.
