This study examined the relationship between children's school adjustment and their emotion regulation. The subjects were 122 1st grade students selected from one elementary school in Incheon. Teachers rated each child using the Emotion Regulation Scale (Lee, 1997) and School Adjustment Scale (Chi & Jung, 2006). The data were analyzed by using descriptive statistics, t-test, correlation analysis, and stepwise regressions. The children's emotion regulation and school adjustment were differed by sex of the child. The girls were assessed to be better adapted in emotion regulation and school adjustment than the boys. The children's emotion regulation was positively related to the children's school adjustment. In addition, the children's emotion regulation predicted how well they would adjust to school life.

This paper presents the construction planning and the detail design of a 16.2 km long railroad tunnel in a mountainous area. Major design conditions for railroad are the single track, loop-typed alinement, and a maximum grade of 24.5$\textperthousand$. A underground station(double track) with a length of 1.1km is located in the middle of the line for train cross-passing. Tunnel is excavated in highly complex geological conditions including faulted areas, abandoned mine works areas, and various rock types such as sandstone, shale, limestone, and coal seam partly. Drilling and blasting method was adopted because it is more flexible than TBM(Tunnel Boring Machine) as a result of risk assessment for geological conditions in this area. Two working adits were planned to adjust the construction schedule and can be used for ventilation and maintenance in operation phase. New material and concept were introduced to the tunnel drain design. They are expected to improve tunnel drain condition and capability. Rational tunnel support design was tried to consider the various tunnel size and purpose and to use the geological investigation results.

The Revised Classroom Play(RCP) scale was validated for Korean 4th grade students. 104 boys and 80 girls took the translated RCP. Test-retest reliability was established with 41 children after 2 months, and test of criterion-related validation was established by the Social Behavior Scale administered to 71 children. All raw scores were standardized by classroom and sex to adjust for differences in the number of nominators and nominatees. The structure of the RCP resulted in 3 factors, 'sociability-disruptive' and 'shy-isolated', with 28 items similar to the original RCP 3 factors. For criterion-related validity, the correlations between the 3 factors of the RCP and the 3 factors of the Social Behavior Scale were positive. For internal consistencies, Cronbach's ${\alpha}$ of the RCP factors ranged from .77 to .94. Test-retest reliability coefficients ranged from .33 to .51. Analyses of variance revealed good item discrepancies for all 28 items. These results confirm the RCP as a valid and reliable measure of the quality of peer relations.

One second grader, Junsu, was observed 4 times before and after formal multiplication lesson in Grade 2. This study describes how solution strategies in multiplication problems develop over time and investigates awareness of the relation between situation and computation in simple measurement and partitive division problems as informally experienced. It was found that Junsu used additive calculation for small-number multiplication problems but could not solve large-number multiplication problems and that he did not have concept of mathematical terms at first interview stage. After formal teaching, Junsu learned a variety of multiplication solution strategies and transferred from additive calculation to multiplicative calculation. The cognitive processing load of each strategy was gradually reduced. Junsu experienced measurement division as a dealing strategy and partitive division as a estimate-adjust strategy dealing more than one object in the first round.

Polycarboxylate type superplasticizers(PC) have got widely used for making not only high performance concrete but low grade concrete as well. It is known that fluidity of cement with PC is affected by the characteristics of cement especially sulphate ion concentration and hydration activity. But the characteristics of PC also affect the fluidity. The fluidity of cement mortar with various types of PC was measured and critical dosage(CD) and dispersing ability(DA) was calculated. CD and DA is strongly dependent on the type of PC. And the variation of fluidity on time was affected by the type of PC also. So, it is advisable to investigate the property of PC before production of concrete and adjust it to meet the requirements of concrete depending on the materials, the time of transport and so on.

School adjustment of elementary school children is one of the most important things,sinceitisthebasisofthefuturelife. The purpose of this study was to investigate the relationships between parent-child relationship, peer relationship, teacher-child relationship, and school adjustment of elementary school students. The research topics of the present study were as follows: (1) Is the school adjustment of elementary school students different depending upon the parent-child relationship? (2) Is the school adjustment of elementary school students different depending upon the peer relationship? (3) Is the school adjustment of elementary school students different depending upon the teacher-child relationship in school? (4) Is the school adjustment of elementary school students different depending upon the grade, and sex? 460 students were sampled in Kangwon-do, and 400 were used in the final data analyses, excluding 60 due to the incomplete answering. Parent-child relationship inventory, peer relationship inventory, teacher-child relationship scale, and school adjustment scale were used. Data were analyzed using SPSS(win) 10.1K. The results were as follows: First, elementary school students adjust themselves to the school better when parent-child relationship, peer relationship, and teacher-child relationship are good. Second, teacher-child relationship has the most important effects on the school adjustment, and peer relationship, and parent-child relationship sequentially. Third, 4th graders adjust to the school better than the 6th, and there is no difference between boys and girls in terms of school adjustments. Based on the above results, discussion and implications for the future research and education were as below: First, teachers need to understand children's school adjustments depend upon their human relationships especially upon teacher-student relationships. Second, teachers need to understand students have more difficulties in adjusting to the school when they grow older. Third, teachers have to keep the children positive peer relationship, and parent-child relationship which are important in children's adjusting to the school. Fourth, future researches need nation-wide sampling and more systematized research design in order to generalize the results.

One of the difficulties of female-headed families face is economic hardship. Low-income single mothers work long hours, become isolated and feel burdened for dual roles. And many of them don't have relatives to share parenting roles. As a result, children of low-income female-headed families are easy to be neglected and left to form a delinquency-prone group in neighborhood. Traditionally, it has been viewed that children in female-headed families have problems due to the loss of father role. However, study indicates that these children can adjust well if the relationship between mothers and children is consistent and adequate. An Intervention program for low-income female-headed elementary children was developed and delivered in two community social welfare centers. The purpose of the program is to raise self-esteem. Two goals were 1) management of daily living habits and 2) improvement of family relations. Social workers maintained contact with mothers to talk about children's behaviors and to prompt hugging and touching. In addition, workers helped children to form good relationships with peers and school teachers. Children were satisfied with the program. Their family relations were improved statistically significantly after the program(wilcoxon signed rant test z=-2.934 p<.05). However, their self esteem were not improved significantly (wilcoxon signed test z=-1.173 p>.05). Qualitative analysis of each children were also discussed. The implications of the study are the followings: Intervention programs need to be delivered separately for low-grade and high grade elementary children because they have different developmental needs. The program also need to include education on sex and marriage as well as aggression reduction. Society needs to provide more support to single mothers for their personal and parenting needs.
