This study examine the mediating role of teacher-child relationships on children's effortful control and problem behaviors. Boys and girls were analyzed separately. Participants were 221 children(l21 boys, 100 girls; aged 4-5), their mothers and 19 child care teachers. The teachers completed rating scales to measure the perception of teacher-child relationships and the children's problem behaviors. Children's effortful control was rated by the mother's questionnaire. The collected data was analyzed using descriptive statistics, t-tests, Pearson's correlations, and hierarchical multiple regressions. Results indicated that children's effortful control was negatively related to their problem behaviors. In addition, the associations between children's effortful control and their aggressive behaviors were mediated by conflictual teacher-child relationship. Also, the relation of girl's effortful control and her withdrawal behavior was partially mediated by conflictual teacher-child relationship. Finally, the association between boy's effortful control and his withdrawal behavior was mediated by close teacher-child relationship. Results suggest the importance of teacher-child relationships in the context of intervention planning for preschooler's problem behaviors.

The study aims to investigate the children's adaptability to early school circumstances and their relationships to teachers and to peers. The examination was done on 110 children aged 4 or 5 at a kindergarten and two child care centers in Seoul. Their 'adaptability to early school' and their 'relationships to teachers and to peers' were rated by their teachers. On the whole, the children subjects are on good terms with their teachers and peers, and they adapt well to early schools. But according to age groups, there were significant differences in the teacher-to-child relationships. Compared to boys, girls show more' adaptability to the early schools', more 'closeness to teachers' and more 'prosociality in peer group'. The 'closeness to teachers' has a positive relation to the 'sociability', 'prosocial behaviors' and 'leadership of peer group', but the 'conflict with teachers' has a negative relation to the peer group relationships. And the' children's relationships with teachers and with peers' were significantly related to their early school adaptability. The 'prosociality', the 'closeness' and the' dependency' were significantly related to the' adaptability to early school' in order.

Purpose. This cross-sectional survey was conducted to described the compliance of Breast Self-Examination of middle-aged women using a convenient sample, and to examine relationships between the compliance of BSE and Health Beliefs, and the influencing factors on the compliance of BSE. Methods. The subjects were 373 literate volunteers who were from 41 to 60 years of age who visited 6 public health centers. From June 7, 2004 to August 20, 2004, data were collected by 5 research assistants using a self-report questionnaire. The questionnaire was used to obtain information on the general characteristics, knowledge, health beliefs, and compliance of BSE. Results. The findings of this study suggested that there were significant differences in the scores of the perceived susceptibility and severity between compliers and non-compliers of the BSE. BSE compliance was significantly correlated with knowledge, perceived susceptibility, and perceived severity. The most powerful predictor of BSE compliance was the perceived susceptibility. The perceived susceptibility, the perceived severity, the knowledge and educational level accounted for $41.8\%$ of the variance in middle aged women's BSE compliance. Conclusion. Increase in knowledge about breast cancer, with a concomitant increase in both perceived susceptibility and perceived severity could produce a subtle cue or motivating force sufficient to affect a behavior change. Further research is needed to examine the qualitative difference between BSE and other early detection behaviors.

The purpose of this study was to investigate the relation of social support and aggression of early adolescents. The subject were 220 adolescents aged 11 & 14 years, who were enrolled 11 child welfare facilities or 6 public schools(3 elementary & 3 middle schools) in Seoul. That is, 110 institutionalized(IA) & 110 middle class home-reared adolescent (HA)s were examined. They subjects were asked to complete the questionnaire on social support and aggression. According to the results, 1)IAs perceived less support from peers or adults and showed more aggressive behaviors than HAs. 2)Significant sex difference was observed in aggression. Girls showed lower level of aggression than boys. 3)Adolescents' aggression was significantly correlated with social support. The more support from friends, classmates, and parents HAs perceive, the less aggression they reported. Though support from peers was correlated significantly only with anger expression, support from parents was correlated significantly with all the components of aggression. And the more support from friends and classmates HAs perceive, the less aggression they reported. These findings implicate that social support is a important factor in preventing aggressive behaviors of early adolescents.

Purpose: The purpose of this study was to investigate the influence of eHealth literacy, reproductive health knowledge, and self-esteem on early adult women's health-promoting behaviors (HPB). This study was based on Pender's health promotion model as a theoretical underpinning. Methods: Early adult women aged 18 to 35 years (n=165) were recruited by posting advertisements on social network sites for a student club and a faith-based community in Ansan, Korea. Willing individuals were invited to participate in the online survey from June 1 to June 30, 2022. Standardized instruments were used to measure HPB, eHealth literacy, reproductive health knowledge, and self-esteem. General characteristics included income level, perceived subjective health, and internet usage time. The collected data were analyzed using the independent t-test, one-way analysis of variance, Pearson correlation coefficients, and multiple regression. Results: The mean age of the respondents was 21.97±3.87 years. The total HPB score was 120.69, corresponding to a moderate level; and the total scores for eHealth literacy (30.24), knowledge of reproductive health (23.04), and self-esteem (35.62) were higher than the midpoint. The model explained 53.3% of variance in HPB, and self-esteem (β=.48, p<.001) was the most influential factor. Other influential factors were, in descending order, higher economic level, higher subjective health status, greater eHealth literacy, and less internet use time (<2 hours/day). Conclusion: In order to promote the health of early adult women, counseling or programs that positively improve self-esteem appear promising, and eHealth literacy should be considered as a way to promote HPB using information technology.

This study aimed to develop and evaluate a sugars intake reduction program (SIRP) that was designed to increase the knowledge, attitude, and skills of Korean children aged 5 years regarding sugars intake reduction. A total of 101 children aged 5~6 years from 6 preschools participated in SIRP. SIRP consisted of 4 sessions including 10 activities (e.g., story-telling, arts, experiment, checking nutrition facts, pledge), delivered to children at preschools by nutritionists over a one-month period. Three letters were sent to parents throughout the program to inform them of the children's activities at the preschools and to provide additional information on reducing children's sugars intake. A total of 90 children completed the program; 83 parents of these children completed the SIRP evaluation survey. The children's sugars intake reduction score was significantly increased after attending SIRP. Teachers (n=6) who participated in this program agreed to improve their students' attitudes on reducing sugars intake and to decrease students' behaviors related to sugars intake. Parents agreed to improve their children's attitude on reducing sugars intake and to decrease children's behaviors related to sugars intake. The outcome showed SIRP improved participants' attitudes towards sugars reduction and increased the skills to reduce the sugars intake of children aged 5~6 years. Future studies should examine whether SIRP reduces actual sugars intake among children.

내구성에 대한 중요성이 부각됨에 따라, 주요 열화현상인 탄산화에 대한 연구가 많이 진행되고 있다. 그러나 탄산화에 대한 연구는 주로 탄산화 깊이의 도출에 국한하고 있으며 경화된 콘크리트를 가정하므로 실제적인 탄산화 거동과는 많은 차이를 보이고 있다. 강재와는 다르게 콘크리트는 공극률과 내부의 수화물의 거동이 매우 중요한데, 탄산화 진행에 따라 초기재령에서 결정되어지는 거동 (공극률 및 수화물)이 다르게 변화한다. 열화 물질의 이동은 주로 콘크리트의 공극률 및 포화도에 의존하므로, 탄산화 후의 거동 평가는 장기열화해석 및 복합열화해석 등에 고려되는 것이 바람직하다. 공극률의 경우, 변화된 공극률이 고려되지 않으면 확산계수의 감소가 구현될 수 없으며 이에 따라 과다한 탄산화 해석을 야기하게 된다. 한편 수화물, 특히 수산화칼슘의 잔존량 평가는 탄산화 깊이의 평가 및 내부 공극수의 특성 변화를 결정하기도 하며, 복합열화에서 발생하는 고정화 염화물량에 큰 영향을 주게 된다. 그러므로 실내 실험들을 통한 공극률 및 수화물 분석은 최근들어 탄산화에 대해서도 많이 적용되고 있다. 본 연구는 미세 관측 실험을 통하여, 탄산화 전후의 공극률 분포 변화, 수화물 거동의 변화를 실험적으로 수행하였다. 공극률 측정으로는 MIP 실험을, 수화물 변화에서는 TGA 실험을 수행하였으며, 기존의 해석 모델인 다상복합수화발열모델 및 미세 공극 구조 형성모델을 개선하여 각각의 탄산화 이후의 공극률 변화 및 수화물 변화를 개발하였다. 개발된 각각의 모델의 결과는 탄산화 전후의 공극률 및 수화물의 변화를 잘 예측하였으며, 탄산화 이후의 열화현상 등에 기초적으로 사용될 수 있을 것으로 평가되었다.

BACKGROUND/OBJECTIVES: This study aimed to identify preschool children's eating behaviors associated with early childhood obesity and its multi-level, socio-ecological determinants. SUBJECTS/METHODS: In a cross-sectional study of 364 mothers of preschool children aged 3-5 years, these children's healthy eating behaviors were assessed using a validated preschool nutrition quotient (NQ-P) questionnaire. The children's overweight or obesity statuses were determined based on body mass index percentiles from the 2017 Korean National Growth Chart. The associations between the NQ-P score and risk of overweight or obesity were examined using multivariable logistic regression. The associations of individual, maternal, physical, and media environmental factors with the NQ-P score were also examined using multivariable linear regression. RESULTS: Preschool children with greater NQ-P scores were at a significantly lower risk of overweight or obesity (P < 0.01). The NQ-P score had a significantly positive association with maternal body mass index and an inverse association with household income (all P < 0.05). Maternal parenting and feeding practices exhibited associations with the NQ-P score. Positive associations were observed with "warm," "structured," and "autonomy-supportive" parenting as well as monitoring feeding practices (all P < 0.05). In addition, the NQ-P score had a significantly positive association with the childcare center's anti-obesogenic environment, such as the provision of nutritional and physical-activity support and vicinity of the built food environment to the home, including access to good-quality food, fruits and vegetables, and low-fat foods (all P < 0.05). Regarding media environments, the NQ-P score demonstrated more significant associations with viewing and eating and/or cooking content displayed on online video platforms (all P < 0.05) than with that on television. CONCLUSIONS: Our findings confirm the significance of healthy eating behaviors in early-childhood-obesity prevention and underscore the importance of multilevel maternal, physical, and media environmental interventions that effectively guide eating behaviors in preschool children.

In this study, the influence of mothers' parenting behaviors on children's strategies and competence of emotional regulation was examined. Further, the mediating effects of children's active-social support seeking and aggressive strategies on the above relationship were explored. The participants were W mother-child pairs. The children were 5th and 6th graders at two elementary schools in Kyunggi province and Kwangju metropolitan area The data were analyzed with descriptive statistics, factor analysis, Cronbach's alpha, Pearson correlations, standard multiple regressions and structural equation modeling analysis by LISREL 8.3. The main results of this study were as follows: (1) The more the mothers coached children with affection and reasoning, the more adaptive emotional regulation the children had; whereas children tended to have maladaptive emotional regulation in response to the mothers' rejecting and forceful parenting behaviors. Also, when children were coached by mothers with love, reasoning and consistent restriction, they used more active-social support seeking strategies, whereas they used more aggressive strategies when the mothers coached children with rejecting and forceful parenting behaviors. The more the mothers were rejecting, forceful and intervening, the more the children used passive-avoidant strategies. (2) The more the children used active-social support seeking strategies and the less the children used aggressive strategies, the more likely they had adaptive emotional regulation. The more the children used aggressive strategies, the more likely they had maladaptive emotional regulation. (3) Children's active-social support seeking strategies played a partial mediating role between mothers' affectionate and reasoned coaching and children's adaptive emotional regulation. These strategies, on the other hand, played a full mediating role between mothers' consistent restriction and children's adaptive emotional regulation. Children's aggressive strategies played a partial mediating role between mothers' rejecting and forceful parenting behaviors and children's maladaptive emotional regulation. Mothers' non-intervention had an influence on neither the children's aggressive strategies nor their maladaptive emotional regulation.
