This study examined the influences of participation in the free semester on school life satisfaction and interest in classes and whether the effect persisted longitudinally. The participants were students from middle schools located in large cities: 451 students in the experimental group and 466 students in the control group. Only the students of the experimental group participated in the free semester. The data were collected at the end of the free semester for three years, and the results are as follows. First, the school life satisfaction of students in the experimental group was significantly higher than those in the control group until the second year but not in the third year. Second, there was no difference in interest in the main subject classes between the experimental and control groups until the third year. Third, students' interest in art and sports classes in the experimental group was significantly higher than those in the control group until the second year but not in the third year. These findings suggest that long-term planning and management of the institution rather than short-term introduction is required for the continuous effects of the free semester.

This study was conducted to identify profiles of loners and those likely to suffer academic burnout among middle school students and to determine whether these profiles differed by gender, ego-resilience, ego-weakness, and school adaptation. The participants in this study were 270 middle school students in Kyung-nam. The results showed that there were four main profiles of students related to their likelihood of being loners and suffering academic burnout: the adaptive group, which had a low tendency towards both loneliness and academic burnout; the burnout group, which had a high tendency towards academic burnout but a low tendency towards loneliness; the lonely group, which had a high tendency towards loneliness but a low tendency towards academic burnout; and the loner-burnout group, which had high tendencies towards both loneliness and academic burnout. Cross-tabulation and one-way ANOVA analyses of the four groups showed that the loneliness-burnout group had a statistically lower level of ego-resilience, higher level of ego-weakness, and lower level of school adaptation than the other groups. This paper discusses the implications for counseling middle school students and presents suggestions for future research.

The purpose of this study is to examine the effects of emotional arousal and cognitive load on pupil diameter during a lie detection interview. The guilty group (n = 30) committed a mock crime (i.e., stealing cash) and the innocent group (n = 30) performed a mission (i.e., sending a message) in the research assistant's office. After that, their pupil size was measured using a wearable eye-tracker during the interview. The interview questions were classified with the three cognitive load, three emotional arousal, and three neutral questions. The results indicate that the main effects of group and time were not significant, but the interaction between group and time was significant. It means that when answering cognitive load questions, the guilty group showed larger increase in pupil diameter than the innocent group. The present study suggests that inducing cognitive load is more effective than inducing emotional arousal during an interview when using pupil diameter as an index of deception, and it is expected to improve the accuracy of lie detection.

Recently, 'Apartment community facilities' have emerged as the most optional factor in the apartment market, and their level is becoming very important. Therefore, this study derived each type through latent profile analysis centering on health-related community facilities in 126 domestic main apartment complexes, and as a result of the analysis, it was confirmed that it was divided into a Pilates group, GX and Yoga group, Golf and Table Tennis practice range group, and overall low group. Among the four groups, Pilates, GX, and yoga groups are more likely to belong to Gangnam, Seocho and Songpa compared to complexes with many golf and table tennis practice ranges, and at the same time, the transaction price is also the highest. Through these analysis results, it was suggested that changes in the preference for leisure activities should be reflected when constructing community facilities, and that health-related community facilities should be deeply considered in residential welfare policies in consideration of high preference for fitness facilities in youth housing.

This research investigated the influence of subjective well-being on attitude towards minority group members. In a cross-sectional data, the higher subjective well-being predicted more positive cognitive beliefs, affective feelings, and behavioral intentions towards foreign laborers and children of international couples. The causal link from subjective well-being to greater tolerance for cultural diversity was found again in a large longitudinal sample. The rate of life satisfaction increase from Time 1 to Time 2 significantly predicted multicultural receptiveness at Time 2. Overall, the findings suggest that subjective well-being may contribute to the formation of favorable attitude towards minority group members.

The purpose of this study is twofold: (i) to develop a teaching and learning plan and practical performance assessment tools for the improvement of teenager-parent communication and relationships as well as explore their effects on the communication in the everyday family life; and (ii) to find the underlying problems of teenager- parent communication through conversation analysis and to provide a improved dialogue model. We provided the experimental group with a performance task of communication training between teenagers and their parents in the real family situation while the control group practiced communication skills in a learning situation. However for both classes, before and after performance tasks were equally provided. The experimental group exhibited a longer conversation time with their parents, better communication skills, and higher degrees of relational satisfaction than the control group. Conversation analysis revealed that the experimental group reduced the use of blocking techniques in the teenager-parent conversations more than the control group, and all so raised the frequency of functional communications more than the control group. In both areas of communication in the experimental group was significantly improved, Most notably, a problem-solving case through no-lose conflict resolution methods was effective, succeeding by 70% in the e experimental group and 43.3% in the control group. Parents use blocking techniques like admonition, lecturing, blaming. sarcastic remarking, ordering and so forth, while teenagers use dispute, avoidance, blaming, and teasing in this order. The communication problems during the conversation process, teenagers' evasive and rebellious way of speaking instigates adverse communication responses from parents, so their conversation tends to unfold as ambiguous evasion opposed to: inquiring or evasion by short answers vs. ordering-preaching, or disputing vs. criticizing-making sarcastic, disputing vs. disputing-teaching, and criticizing vs. criticizing.

This study investigated the association among parental socioeconomic level, overweight, and eating habits with diet quality in Korean sixth grade school children. A 3-day dietary survey was conducted, and a questionnaire and anthropometric data were collected from the Korean child obesity cohort (320 boys and 345 girls). The children were classified into two groups (low or high level) based on monthly household income and paternal and maternal education status. Lower maternal education status was associated with a higher risk for overweight in girls (odd ratio, 1.91; 95% confidence interval 1.07-3.44), whereas belonging to a higher socioeconomic group in terms of parental income or parental education level resulted in the consumption of significantly more fruit. Boys did not show significant differences in the intake of most nutrients or diet quality regardless of socioeconomic status. However, girls in the lower socioeconomic group had a lower food habit score (higher frequency of breakfast skipping and ramen noodle consumption), diet quality, and intake of nutrients (carbohydrate, vitamin C, potassium, and fiber) than those in the higher socioeconomic group. Therefore future nutrition policies and interventions should support parents and children with lower socioeconomic status to develop health-related behaviors that may prevent childhood overweight.

Genetic parameters for growth and carcass traits were estimated on the basis of the data from 3,415 heads of Hanwoo bulls tested at Livestock Improvement Main Center. The data were divided into two groups : the first period group consisted of 1,592 heads of bulls tested in individual pens from 1986 to 1990 and the second period group consisted of 1,823 heads of bulls tested in group pens from 1991 to 1996. The testing period was from 6 to 18 months of age in the first period group and 10 to 22 months of age in the second period group. The average daily gains during 6 to 12 months and 12 to 18 months were 1.01kg and 0.77kg, respectively, in the first period group and 0.80kg and 0.95kg in the second period group, and the compensated growth appeared to have occurred in the second period group. The heritability of body weight at 12 months estimated was 0.37 during the first period and 0.47 during the second period. The heritability of body weight at 18 months was 0.29 during the first period and 0.33 during the second period. The heritability of average daily gain during 6${\sim}$12 months estimated was 0.26 for the first period and 0.33 for the second period. The heritability of average daily gain during 12${\sim}$18 months estimated was 0.11 for the first period and 0.22 for the second period. The heritabilities of body weights and average daily gains estimated tended to be higher in the second period than in the first period. The heritability of body measurements at 12 months during the first period estimated was 0.30 for withers height, 0.25 for rump height, 0.11 for thurls width and 0.13 for chest girth. The heritability of body measurments at 12 months during the second period was 0.53 for withers height, 0.44 for rump height, 0.36 for thurls width and 0.56 for chest girth. The heritabilites of withers height, rump height, thurls width and chest girth at 18 months of age were 0.40, 0.22, 0.12 and 0.21 during the first period and 0.45, 0.42, 0.42 and 0.35 during the second period, respectively. The heritability of carcass traits estimated during the first period was 0.11 for carcass weight, 0.24 for dressing percent, 0.25 for eye muscle area, 0.18 for backfat thickness and 0.21 for carcass length. The heritabilities of carcass weight, dressing percent, eye muscle area, backfat thickness, carcass length and marbling score during the second period estimated were 0.32, 0.52, 0.33, 0.51, 0.58 and 0.31, respectively. The genetic correlations between the first and second periods estimated were higher than 0.8 for chest girth at 12 months, rump height at 18 months, carcass weight and dressing percent, but were lower for other traits.
