  • This study was designed to recognize the importance of prosocial behavior, aimed at developing and utilizing a tea ceremony education program to foster prosocial behavior in children to be used in pre-school during early childhood when basic behavioral patterns are established. The sample was composed of 90 children from K pre-school located in GangDong-Gu and 90 children from K pre-school located in Jung-Gu. Their ages varied from 3 to 5 years old and the family's financial position was approximately middle class. The results were as follows, the change in children's prosocial behavior according to the group showed that childhood tea ceremony education through the tea ceremony education program affected the improvement in children's prosocial behavior. This suggests that childhood tea ceremony education are useful for improving children's basic habits and prosocial behavior, as well as character education.

  • It needs theoretical assessment fundamental for informatics curriculum to judge appropriate grades and measure academic standard of an learner according to be included in the conventional curriculum. Thus this study tried to present an criteria on programming area of an informatics curriculum through bloom taxonomy and knowledge type. And it presented assessment criterion on each steps from "Remember" to "Create". And we presented knowledge type examples of programming such as Factual to Metacognitive based on Bloom's knowledge types. Also we analysed that most important level or type is Apply Level, Create Level and Procedural Knowledge. We investigated for each criterion of programming assessment based on bloom's theory through Delphi method. And the result of this investigation was that area of bloom's taxonomy was CVR 0.90, Validity 0.85 and area of knowledge type was CVR 0.90, Validity 0.79. So it can decide to accept for our assessment criteria of programming education based on Bloom theory.

  • In the present study, we investigated the effects or hydrostatic pressure and stacking sequence on the elastic work factor to determine compressive fracture toughness of graphite/epoxy laminated composites in the hydrostatic pressure environment. The stacking sequences used were unidirectional. $\textrm{[}0^{\circ}\textrm{]}_{88}$ and multi-directional, $\textrm{[}0^{\circ}/\pm/45^{\circ}/90^{\circ}\textrm{]}_{11s}$. The hydrostatic pressures applied for a $\textrm{[}0^{\circ}\textrm{]}_{88}$ case were 0.1 MPa, 70MPa, 140MPa. and 200MPa. The hydrostatic pressures applied for a $\textrm{[}0^{\circ}/\pm/45^{\circ}/90^{\circ}\textrm{]}_{11s}$ case were 0.1MPa, 100MPa, 200MPa, and 300MPa. It was found that the elastic work factor was not affected by the hydrostatic pressure and the stacking sequence. Also, it was found that the elastic work factor decreased in a linear fashion with delamination length.

  • The purpose of this study was to find out the effects that daughters' incomplete lactation records affect sire's breeding values through genetic evaluation using RRTDM(random regression test-day model). First, we estimated genetic parameters and breeding values on sires having complete lactation records of daughter by RRTDM, second, we changed complete lactation records of specific sires into incomplete records by various methods. Third, the breeding values were compared between complete and incomplete records. Finally, this study aimed to find out the methods to minimize the estimation errors of young bulls' breeding values. Data used in this study were collected from the dairy herd improvement program, and a total of 97,562 records were composed of 10,929 first parity with both parents known, since 1999. Breeding values on the daughters from randomly chosen sires were calculated and compared with among 90 day, 150day, and 200 day's incomplete records. For milk yields, sire's ranks of breeding values used by complete lactation records were very different from sire's ranks of breeding values obtained by incomplete lactation records(Rank_90 cut, 150cut, 200 cut).The differences were also obtained between complete lactation records(per305_full) and incomplete lactation record (per_90 cut, 150cut, 200 cut) in breeding values regarding persistency. Especially, the differences between per_90 cut and per305_full were very large(from 1.8 kg to 145kg).
