The relationship between children's behavior problems and perceptions of their parents' childrearing behaviors was studied in 359 fourth graders. Children reported on perceptions of their parents' childrearing behaviors with the Childrearing Behavior Questionnaire (Park, 1995) and on their own behavior with the Korean Youth Self-Report (K-YSR; Oh, Lee, Hong, & Hah, 1997). Data were analyzed with descriptive statistics, t-test, and hierarchical multiple regression. Results showed that girls viewed their fathers and mothers as more warm/accepting and their fathers as less rejecting/restricting than boys. Boys had more externalizing (aggressive/delinquent) behavior problems than girls. Children's internalizing behavior problems were positively related to their perceptions of paternal and maternal rejection/restriction and permissive/non-interfering. The relationship was differed as a function of child's sex. Children's externalizing behavior problems were positively related to their perceptions of paternal and maternal rejection/restriction and paternal permissive/non-interfering. The relationship was differed as a function of child's sex.

The purpose of this study was to investigate the effects of early storybook reading intervention participation on the first graders' language abilities in low income families. The subjects consisted of 148 first graders and their primary caregivers. The intervention group was composed of 100 first graders who participated in the early storybook reading intervention program in childcare or kindergarten. The comparison group comprised 48 first graders from equivalent social and economic backgrounds, who did not participate in the program. The language abilities of the children were tested and questionnaires regarding the home literacy environment, children's reading activities at home and parents' perceptions of their children's reading behaviors were completed by the children's primary caregivers. The data were analyzed by means of structural equation modeling. The results indicated that early intervention participation was directly associated with children's higher language abilities in first grade and indirectly influenced the children's language abilities through the home literacy environment, children's reading activities at home and parents' perceptions of their children's reading behaviors.

The purpose of this study was to develop a basic life habit scale for infant early childhood. The participants of this study were composed of 1,000 parents of children aged from two to five years old in the Seoul, Gyeong-gi, and In-cheon areas. For the purposes of data analysis, the study made use of the following methods : descriptive statistics for SES variables, item-analysis, factor analysis for validity, and Cronbach's a for reliability. Most items were acceptable in terms of item response rates, and item discrimination. The results of factor analysis uncovered six factors, and 46 items were selected from a total of 69 items in the original scale. The six factors were (1) safety and rules (2) neatness (3) manners (4) self-help (5) eating habits (6) cleanliness. Cronbach's a value for the reliability of the factors ranged from .76 to .94.of Cooperative Learning. Methods. Westport, CT : Greenwood Press.

We propose a new method to deal with the optimized auto-tuning for the PID controller which is used to the process-control in various fields. First of all, in this method, 1st order delay system with dead time which is modelled from the unit step response of the system is Pade-approximated, then initial values are determined by the Ziegler-Nichols method and deciding binary strings of parents generation using by the fitness values of genetic algorithms, we perform selection, crossover and mutation to generate the descendant generation. The advantage of this method is better than the Ziegler-Nickels method in characteristic of output, and has extent of applying without limit of K, L, T parameters.

압출공법(incremental launching method)은 교대 배후에 거더 제작장소를 설치하고, 콘크리트를 이어쳐서 교량거더를 제작하고, 이것을 잭(jack)으로 밀어내는 가설방법이다. 이 공법에 의해 시공되는 교량의 상부단면은 시공 중에 지간의 중앙부와 지점부에 일시적이나마 모두 위치하게 된다. 따라서 단면들은 자중에 의해 발생되는 최대 정모멘트와 최대 부모멘트, 그리고 최대 전단력을 모두 경험하게 되는 구조적 특성을 가지고 있다. 한편 거더의 캔틸레버 작용을 감소시키기 위하여 거더의 선단에 압출추진코(launching nose)를 부착시킨다. 상부단면에 발생하는 이 일시적인 응력의 크기는 압출추진코의 단면특성에 따라 달라진다. 본 논문에서는 압출추진코와 상부단면의 상호작용에 관한 해석식의 정확성을 유지하고, 활용도를 높이기 위해서 압출추진코를 유사등단면(강성;등단면, 중량;변단면)으로 가정하여 단순화된 해석식을 제안하였고, 압출추진코의 단면이 등단면으로 가정한 기존 해석식의 정확성을 향상시키기 위해서 다이아프램의 중량을 집중하중으로 치환시켜 변형된 등단면 해석식을 제안하였다. 그리고 제안된 2개의 해석식의 정확성과 활용성을 판단하기 위해 실제 ILM교량 설계자료들을 통해 전산구조해석 프로그램과, 기존 해석식들과 비교 분석 하였다.

This study aimed to find the general tendencies of parental family-of-origin experiences and conflict and their children's behavioral problems as a function of a child's sex, as well as the causal relationships among these variables. Three hundred and five 4th and 5th graders filled out the Korean Version of Achenbach's Child Behavior Checklist. Parents of these children answered the Family-of-Origin Scale and Marital Conflict Inventory. The results were as follows. 1) Fathers experienced more of emotional cut-off from their family of origin than mothers did. However, mothers had more of triangulation and emotional separation from their family of origin than fathers did. 2) Both fathers and mothers reported that mothers had more of marital conflicts. 3) Daughters showed more physical symptoms than sons while sons showed more delinquent behaviors. 4) While parental experiences from the family-of-origin effected the parents' marital conflicts, they didn't influence the children's behavioral problems through marital conflicts.

In this paper, we suggest the algorithm that inserts or deletes documents into web sites without creating tag. This algorithm uses tag which links between documents to automatically inset or delete the web documents. This study extracts the texts in the ... tag of the document to put into the structure as a type of graph creating the link as a node m of sub-node. That is, in this case of configurating new link between web documents, this algorithm allows to insert or delete the node to or from the graph without creating the tag. In the case of deleting the document, it removes the broken link connecting the sub-nodes of deleted node newly to its parent node.

This study examined frequency of contact between parents and their non-coresident, never-married daughters and sons compared to children in other marital statuses. Despite an increasing number of never married adults, little is known about the extent to which they may be willing to remain connected to and exchange support with their parents. The data were drawn from first wave of the Korean Longitudinal Study of Ageing (KLoSA, 2006). For analyses, respondents who had at least one non-coresident child aged 40 or older were selected, resulting in the analytic sample of 2,755 parents with 7,741 children. Both sibling fixed effects regression models and regression models with robust standard errors were estimated using the xtreg and reg procedures in STATA. Findings revealed significant marital status by gender interaction effects on face-to-face contact. Never-married daughters were more likely to see their parents compared to their married, divorced, or widowed counterparts. Never-marred sons, on the other hand, reported slightly lower levels of in-person contact with their parents in comparison to married sons and lower levels of contact compared to divorced or widowed sons. More frequent contact via phone, mail, or email was reported in daughter-parent relationship compared to son-parent relationship, but no significant marital status by gender interactions were observed.

Applying the perspective of Comprehensive Community Initiatives (CCIs), this paper attempted to examine community development practice for children. Using focus group interviews, this qulitative research study collected data from six social workers in Guryonpo-village(fishing village) and Ganeong 1-dong village(city village), all of whom have experience in community development practice for children. The main results were as follows: First, it was found to be important to access the community in the initial stage of CCIs. Second, indigenization strategies were useful for the fishing community. Third, it was important to organize parents of children in poverty. Lastly, the community development practice was more successful in the fishing village than in the city village.
