A nutrition survey of elementary school children in urban areas was undertaken in December of 1986, to investigate nutritional status in relation to school lunch programs. A total of 284 children in the grades from the 4th to the 6th of Myongsudai elementary school, consisting of three groups ; 1) children taking school lunch every day, 2) children taking school lunch intermittently, 3) children not taking at all, were studied. The group of children taking school lunch every day showed higher values of dietary intake, anthropometric measurements and biochemical findings, compared to those of the other groups, in general. These data underscore the necessity of nation wide school lunch programs for whole school children of Korea.

Understanding the interplay between galaxies and dark matter in the universe is one of key challenges in modern astrophysics. This provides an important test of structure formation scenarios and cosmological models. I discuss three aspects of this test: (1) comparing the matter distribution from galaxy redshift surveys with that from weak-lensing surveys, (2) statistical comparison of large-scale structures between observations and cosmological simulations, and (3) multi-wavelength study of galaxies. These tests underscore the importance of combining photometric and spectroscopic surveys in observations along with cosmological simulations for exploring and understanding the structure formation.

This study is designed to extent the investigation of the Kyongbuk Womens policy the area of family life and womens economic activity. Results indicated that the primary barriers of getting a job for married women was child rearing and the diffency of working information. On the family life, communication patterns were contributed to the problem of the relationship between child and parent, and spouse relationship. And also, school violence was founded the hot problem. The results underscore the importance of child rearing support system, and affirmative action in womens employment enviroment, Family Life Educator and Family Counselor.

In 2013, Academy Award for Best Animated Short Film was granted to Walt Disney's short animation, (2012). With various aspects of its excellence, I focus on the very effective use of digital lightings and underscores for storytelling as its success factors. In this respect, this paper aims at analyzing the roles of the visual factors, especially tone, contrast, etc. created by lightings, and audio factors, especially underscores, in the film's story development. I find that can be characterized by the well-built story structure with distinct three acts. The main stream of the story is expressed with the overall mood that is created by the fine adjustments of brightness of the main light, and contrast. And the direction and the intensity of the lighting successfully describe the emotions of the characters in each scene. In addition, I find that properly chosen and positioned underscores make the development of the story more dynamic and more harmonized.

This study examined relationships between caregivers' attachment, young children's emotion regulation, and aggression. Subjects were 110 institutionalized and 105 home-reared children (M=3.8 and 4.2 years, respectively). Data were collected from children's caregivers via questionnaires and analyzed by ANOVA, correlations, and hierarchical regressions. Results showed that (1) caregivers' attachment and the emotion regulation and aggression of institutionalized children were significantly different from those of home-reared children; (2) caregiver's attachment was positively related to emotion regulation for both institutionalized and home-reared children; (3) for institutional children, negative relationships between attachment and aggression was found for girls; negative relationships between emotion regulation and aggression was found for boys. These findings underscore negative effects of institutionalized care on children's socio-emotional behaviors.

Objectives: Mood disorder is highly comorbid with attention deficit/hyperactivity disorder (ADHD), and comorbid ADHD symptoms are associated with suicide risk. The aim of this study was to examine the association between comorbid ADHD symptoms and the number of suicide attempts among patients with unipolar and bipolar depression. Methods: In this cross-sectional study, 100 patients with either unipolar or bipolar depression constituted the final sample. Pearson's correlation and multiple regression analyses were conducted to examine the association between comorbid ADHD symptoms and suicide risk. Results: Among patients with bipolar depression, the number of suicide attempts was significantly correlated with ADHD symptoms (r=0.324, p<0.01). ADHD symptoms significantly predicted the number of suicide attempts (β=0.249, p<0.05). Conclusion: Our findings underscore the importance of screening and assessing ADHD symptoms in male young adults with depressive disorders.

This study explored the differences in gender, developmental period and parents in terms of parenting, the cross-sectional and longitudinal relationships in parenting by gender, and the cross-sectional and longitudinal relationships between participant roles in bullying situations and parenting by gender. The subjects were 498 4-5th grade children and the instruments utilized in this study were the Parental Bonding Instrument (Bowers, Smith, & Binney, 1994) and the Participant Roles Scale (Sutton & Smith, 1999). The subjects were contacted again one year after the first contact. Results showed that the relationships between parents were longitudinally quite stable. Girls whose fathers had higher levels of accurate monitoring were more likely to be defenders cross-sectionally. Girls whose parents had more accurate monitoring were less likely to be victims longitudinally. The results underscore the importance of examining both gender and participant roles in bullying situations.

Objective: The main purpose of this study was to investigate the direct effect of maternal parenting behavior and indirect effects through preschoolers'executive function on three types of social behavior, prosocial, aggressive and withdrawn behavior. Methods: A total of 299 mothers and their preschool-aged children were the subjects of this study. Mothers completed the questionnaire that included measures of their parenting behavior, preschoolers' executive function, and social behavior. Results: First, mothers' positive parenting behavior had a direct effect on preschoolers' prosocial behavior, and mothers' negative parenting behavior had direct effects on preschoolers' aggressive and withdrawn behavior. Second, mothers' positive parenting behavior had indirect effects on preschoolers' prosocial, aggressive and withdrawn behavior through preschoolers' executive function. In contrast, indirect paths from maternal negative parenting behavior to social behavior through preschoolers' execution function were not significant. Conclusion/Implications: These findings underscore the importance of executive function during early childhood and suggest the need for effective parenting programs to promote executive function.

p11 protein (S100A10) is downregulated in depressive-like states of human and rodent. Antidepressant drug treatment increases p11 levels in rodent models. We reviewed studies demonstrating that p11 levels are regulated in depression and by antidepressant treatment and that p11 upregulation exerts antidepressant effects. Current studies on p11 underscore the importance of p11 as a potential antidepressant target.

The new recycling technology for aged Aluminum wires in overhead conductor have been carried out. We are attempting to develop remanufacturing method for them for more effective way of recycling in stead of its conventional remelting process. The weld of aged aluminum wires play a vital role in remanufacture process. The paper investigates the mechanical properties during cold welding process of aged Aluminum wire. The tensile tests and microscopic analysis results are discussed to underscore the hardening features of welded aluminum wire. Various graphs are presented accompanied by discussion about their relevance on the process.
