The purpose of the study was to observe and categorize daily routines of infant classes in daycare centers based on quantity of indoor and outdoor free play, group activities and nap/rest and explore differences in infants' play and teacher's behavior according to daily routine types. A team of trained observer observed daily routines and teacher's behavior of 26 infant classes from 7 daycare centers for two days and teachers evaluated 164 infants' playfulness. As a result daily routines of infant classes were categorized into two types: "Indoor & Outdoor Free Play Oriented" and "Group Activities & Rest Oriented". Infants' playfulness of "Indoor & Outdoor Free Play Oriented" groups were higher than that of "Group Activities & Rest Oriented" groups. Teachers from "Indoor & Outdoor Free Play Oriented" groups were found to have more experiences in the field and also they showed more positive and neutral guidance than the others.

Purpose: This study was to investigate impacts of daily habits, health status and health promoting behavior on prevalence of irritable bowel syndrome (IBS) among female high school students. Methods: The survey was conducted from 526 female students in high school. Rome III criteria was used to diagnose IBS. Data of daily habits, health status, and health promoting behavior were collected through self-administered structured questionnaires. Results: The prevalence of IBS was 25.7%. Compared to the non-IBS, the IBS group scored significantly lower in exercise time, sleeping time, four dimensions of health status (physical, emotional, social, spiritual health) and management of relationship and stress in health promoting behavior. Risk factors influencing IBS were exercise time, physical health and emotional health status. Conclusion: The results of this study suggest that nursing interventions and education programs are important to be developed, while considering exercise, health status and health promoting behaviors for female adolescents in order to manage their IBS.

The purpose of this study was to investigate the effects of perceived daily stress on the adjustment of children and to examine whether social support has a moderating effect on the relationship between daily stress and adjustment. The results are summarized as follows. First, it was found that stress caused by school, family environments and friends had significant effects on the self-concept of children. In addition, it was found that stress caused by teachers/school and family environments had significant effects on achievement motivation and social behavior. Second, the interaction between daily stress and support from family and friends affected self-concept. Furthermore, achievement motivation was positively affected by the interactions between daily stress and family support, between daily stress and teacher support and between daily stress and friend support.

A brain-enriched secreting signal peptide, NELL2, has been suggested to play multiple roles in the development, survival, and activity of neurons in mammal. We investigated here a possible involvement of central NELL2 in regulating feeding behavior and metabolism. In situ hybridization and an immunohistochemical approach were used to determine expression of NELL2 as well as its colocalization with proopiomelanocortin (POMC) and neuropeptide Y (NPY) in the rat hypothalamus. To investigate the effect of NELL2 on feeding behavior, 2 nmole of antisense NELL2 oligodeoxynucleotide was administered into the lateral ventricle of adult male rat brains for 6 consecutive days, and changes in daily body weight, food, and water intake were monitored. Metabolic state-dependent NELL2 expression in the hypothalamus was tested in vivo using a fasting model. NELL2 was noticeably expressed in the hypothalamic nuclei controlling feeding behavior. Furthermore, all arcuatic POMC and NPY positive neurons produced NELL2. The NELL2 gene expression in the hypothalamus was up-regulated by fasting. However, NELL2 did not affect POMC and NPY gene expression in the hypothalamus. A blockade of NELL2 production in the hypothalamus led to a reduction in daily food intake, followed by a loss in body weight without a change in daily water intake in normal diet condition. NELL2 did not affect short-term hunger dependent appetite behavior. Our data suggests that hypothalamic NELL2 is associated with appetite behavior, and thus central NELL2 could be a new therapeutic target for obesity.

Objective: This study assessed the association between subjective body image or objective body mass index (BMI) and the risk of daily smoking in Korean adolescents, with a purpose of identifying the most suitable models. Materials and Methods: Using the 2013 9th Korea Youth Risk Behavior Web-based Survey data for 72,435 students, odds ratios were calculated for daily smoking in the past month, according to the subjective body image and calculated BMI using a respective multiple logistic regression model. The combined effect of these two factors was also analyzed by pairing a BMI category with a subjective body image category, using odds ratios for the same event within each sex group. Results: Among the surveyed students, 7.2% of boys and 1.8% of girls were classified as daily smokers. Students who perceived themselves as being very obese tended to be at lower risk of daily smoking (OR=0.61 in boys with 95% CI=0.47 to 0.79; OR=0.66 in women with 95% CI=0.47 to 0.93). In addition, boys within the obese or overweight BMI category showed a lower risk of daily smoking (OR=0.86, 95% CI: 0.77-0.96). Lean BMI was significantly associated with higher odds ratios for daily smoking only in female students (OR=1.24, 95% CI: 1.02-1.52). When pairing these two objective and subjective factors, results suggested that subjective body image has a greater effect on daily smoking than BMI in both boys and girls. Conclusions: In both male and female students, subjective body image had a greater effect on daily smoking than body mass index. A model using the combination of BMI and subjective body image was the best fit in girls, in contrast to the model using subjective body image only best suitable in boys, for the prediction of daily smoking. These results including several factors associated with daily smoking in Korean students, provide useful data for the development and implementation of smoking intervention and cessation programs for adolescents.

The ussur brown katydid, Paratlanticus ussuriensis (Orthoptera: Tettigoniidae), causes substantial damage in orchard areas in South Korea. Daily rhythm and mating behaviors were investigated in last instar nymphs, immature adults and mature adults of P. ussuriensis. The daily rhythm was repeated upon resting, moving, and feeding. The daily rhythm of the movement behavior similar in both last instar nymphs and immature adults. Last instar nymphs becoming active at 10:06 and ceasing activity at 21:12 in average. Immature adults becoming active at 11:30 and ceasing activity at 20:08 in average of totally 10 individuals. However, mature adults showed a different active time of 15:30. Generally, behavior was affected by the conditions of their environment, especially temperature. Mature adults activated later than nymphs and immature adults. Mature adults display mating behavior at a particular time of day (approximately 20:00). P. ussuriensis showed a mating behavioral sequence which was similar to related species in completely retaining the spermatophylax. Females took 270 min to 360 min to completely retain the spermatophylax. The daily rhythm of P. ussuriensis, indicating its occurrence and ecology, could be useful as basic data for managing field populations of P. ussuriensis.

This study investigated 1) the effects of mountain climbing motivation on the desired mountain climbing wear benefits, and 2) the desired effects of mountain climbing wear benefits on clothing usage behavior. Data were collected via a questionnaire administered to 498 consumers who make at least one mountain climbing wear purchase for personal use. All items were evaluated on a 5-point Likert scale, and SPSS 20.0 and Amos 7.0 were used for data analysis. Confirmatory factor analysis for the research variables were performed and three factors of mountain climbing motivation (social interaction, health improvement, and mental rejuvenation), four factors of mountain climbing wear benefits sought (ostentation, ideal healthy figure, conformity, and functions), and two factors regarding clothing usage behavior (sportswear usage and daily wear usage) were identified. The results from the model test were as follows: 1) Mountain climbing motivation was found to vary depending on the mountain climbing wear benefits sought. Social interaction had a positive effect on all 4 factors of mountain climbing wear benefits sought. Health improvement was the only motivating factor for consumers who sought the benefit of functions; however, the functions benefit was not found to be a consideration for consumers who climbed for mental rejuvenation. 2) Mountain climbing wear usage was affected by mountain climbing wear benefits sought. The benefits for conformity and functions had a positive effect on sportswear usage and daily wear usage; however, the ideal healthy figure only affected daily wear usage. The twofold usage of mountain climbing wear reflects a cultural trend toward the usage of mountain climbing wear as daily wear; however, consumers show this twofold usage to conform successfully to mainstream society and not to pursue the ideal healthy figure.

The purpose of this study is (1) to explore fathers' interest and involvement concerning their child's education as related to demographic variables of family, fathers' parenting behavior, and participation in the daily life of their children. A total of 220 fathers of children in elementary to high school participated in this study and responded to a questionnaire. T-test, oneway ANOVA, correlation analysis, and regression analysis were used for data analysis. The findings are as follows: 1) The level of fathers' interest and involvement in their child's education was relatively high. 2) Fathers' interest and involvement in their child's education were significantly different according to the father's educational level and socioeconomic status, but not to the child's gender and age. The better a child's school achievement was, the higher the father's interest and involvement in their child's education was. 3) Fathers' affectionate parenting behavior and participation in the daily life of their children affected the fathers' interest and involvement in their children's education. The importance of fathers' interest and participation concerning their child's education was discussed.
