Purpose: This study investigates university students' SNS addiction tendency, trait-anxiety and quality of sleep. This study is going to offer basic resource that required to make the way that is able to reduce the anxiety with figuring out the relation between variable. Method: 213 people participated in this study is 20 to 30 age of university students who use SNS. Collecting resource period was April 4 to May 11, 2018. Analyses consisted of descriptive statistics, ANOVA, Pearson's correlation analysis, and stepwise multiple regression analysis. Results: The findings showed SNS addiction tendency and quality of sleep(r=.45, p<.000). Major Influence factor is predicted addiction tendency of SNS using time (F=21.21, p=.000) and trait-anxiety (F=23.55, p=.000). Of the highest trait-anxiety affects quality of sleep (F=24.82 p=.000). Conclusion: These findings indicate that it is necessary to develop and implement information programs and design appropriate SNS addiction prevention programs that can induce trait-anxiety and improve quality of sleep. Thus follow-up study should have diverse participants to investigate SNS addiction tendency, trait-anxiety and quality of sleep that influenced by overusing SNS.

Objective: The objective of this study was to estimate the genetic parameters for worm resistance (WR) and associated characteristics, using the linear-threshold animal model via Bayesian inference in single- and multiple-trait analyses. Methods: Data were collected from a herd of Santa Inês breed sheep. All information was collected with animals submitted to natural contamination conditions. All data (number of eggs per gram of feces [FEC], Famacha score [FS], body condition score [BCS], and hematocrit [HCT]) were collected on the same day. The animals were weighed individually on the day after collection (after 12-h fasting). The WR trait was defined by the multivariate cluster analysis, using the FEC, HCT, BCS, and FS of material collected from naturally infected sheep of the Santa Inês breed. The variance components and genetic parameters for the WR, FEC, HCT, BCS, and FS traits were estimated using the Bayesian inference under the linear and threshold animal model. Results: A low magnitude was obtained for repeatability of worm-related traits. The mean values estimated for heritability were of low-to-high (0.05 to 0.88) magnitude. The FEC, HCT, BCS, FS, and body weight traits showed higher heritability (although low magnitude) in the multiple-trait model due to increased information about traits. All WR characters showed a significant genetic correlation, and heritability estimates ranged from low (0.44; single-trait model) to high (0.88; multiple-trait model). Conclusion: Therefore, we suggest that FS be included as a criterion of ovine genetic selection for endoparasite resistance using the trait defined by multivariate cluster analysis, as it will provide greater genetic gains when compared to any single trait. In addition, its measurement is easy and inexpensive, exhibiting greater heritability and repeatability and a high genetic correlation with the trait of resistance to worms.

The subjects in this study were 442 5th and 6th grade school children in Seoul. Data were analyzed by Pearson's correlation, Stepwise Multiple Regression, and MANOVA. The principal findings were that worry, depression, and trait anxiety were positively related to meta-cognitive knowledge, particularly, meta-worry, positive beliefs about worry, negative beliefs about worry, lower appraisal about cognitive competence, and cognitive self-consciousness. These traits were also positively related to such metacognitive regulation strategies as worry displacement, self punishment, reappraisal, and social control. Metacognition influenced worry, depression, and trait anxiety; groups having more problems worry, depression, and trait anxiety showed high scores in metacognitive knowledge and metacognitive regulation strategies.

The purpose of this study was to investigate the effect of selected internal and situational factors on children's prosocial behaviors. While child's sex and trait empathy were chosen as internal factors, state empathy and social evaluation were regarded as situational factors. The subjects were 72 bays and 72 girls chosen from 288 eleven-year-olds. This selection was based on their emplathic scores measured by the Bryant Empathy Scale (1982). Half of the 144 children belonged to the high-trait empathic group and the other half to the low-trait empathic group. Within each of the high-and the low-trait empathic groups, equal numbers of boys and girls were randomly assigned to one of the two state empathy conditions and two social evaluation conditions. The state empathy conditions were divided into the arousal condition and the disregarding condition. To control social evaluation, subjects were led to believe that the experimenter either would or would not evaluate their donation of colorful ball-point pens to handicapped children. The data was analyzed by 4-way ANOVA [sex(2)${\times}$trait empathy(2)${\times}$state empathy(2)${\times}$social evaluation(2)]. The results were that (1) children's prosocial behaviors were significantly different by sex, state empathy, and social evaluation, and (2) children's prosocial behaviors were not significantly different by their trait empathy level.

Purpose: The purpose of this study was to identify relationships among trait anger, life styles and physical symptoms in elderly people. Method: The participants were 348 elderly persons over 65 years of age who lived in Seoul, Geonggi Province, South Chungcheong Province and South Jeolla Province. The data were analyzed using descriptive $X^2-test$, t-test, one-way ANOVA and Pearson's correlation coefficient with SPSS win 12.0. Results: Physical symptoms of the participants correlated with trait anger and life style. Trait anger in the elderly people had a significant positive correlation to cardiovascular symptoms. Smoking showed a significantly positive correlation to alcohol drinking and cardiovascular symptoms. Regular diet showed a significantly negative correlation to general symptoms, cardiovascular symptoms and gastrointestinal symptoms. Caffeine intake significantly negative correlation to general symptom and cardiovascular symptom. Conclusion: These results suggested that elderly people with a high degree of trait anger are likely to be high in perceived physical symptoms. Therefore nursing interventions to reduce levels of trait anger and change life style should be provided for elderly people.

The purpose of this study was to detect SNPs that were responsible for a carcass trait in Hanwoo populations. A non-parametric model applying a restricted partition method (RPM) was used, which exploited a partitioning algorithm considering statistical criteria for multiple comparison testing. Phenotypic and genotypic data were obtained from the Hanwoo Improvement Center, National Agricultural Cooperation Federation, Korea, in which the pedigree structure comprised 229 steers from 16 paternal half-sib proven sires that were born in Namwon or Daegwanryong livestock testing station between spring of 2002 and fall of 2003. A carcass trait, longissimus dorsi muscle area for each steer was measured after slaughter at approximately 722 days. Three SNPs (19_1, 18_4 and 28_2) near the microsatellite marker ILSTS035 on BTA6, around which the quantitative trait loci (QTL) for meat quality were previously detected, were used in this study. The RPM analyses resulted in two significant interaction effects between SNPs (19_1 and 18_4) and (19_1 and 28_2) at ${\alpha}$ = 0.05 level. However, under a general linear (parametric) model no interaction effect between any pair of the three SNPs was detected, while only one main effect for SNP19_1 was found for the trait. Also, under another non-parametric model using a multifactor dimensionality reduction (MDR) method, only one interaction effect of the two SNPs (19_1 and 28_2) explained the trait significantly better than the parametric model with the main effect of SNP19_1. Our results suggest that RPM is a good alternative to model choices that can find associations of the interaction effects of multiple SNPs for quantitative traits in livestock species.
