N/A In order to investigate the relationship between the thermal characteristics of the various molds as green sand mold, dry sand mold, CO₂ mold and shell mold, and the solidification characteristics of molten metal, the thermal analysis of rarious molds and melt were performed. The structure of Al-Castings was a/so observed. Results obtained in this experiment were as follows : 1) The heating rate of the molds was increased in the order of green sand mold, CO₂ mold, dry sand mold and shell mold, On the other hand the solidification time of the melts was shortened in the order of dry sand mold castings, CO₂mold castings, green sand mold castings and shell mold castings. 2) The arrest temperature period in the heating curve of the green sand mold was resulted from the eraporation of moisture contained in mold, which was tranafered to the outer side of the mold. 3) The temperature fluctuation of the melt in the shell mold was considered to be resulted from the combution heat of resin contained in the mold. 4) The amounts of heat absorption of the molds were increased in the order of dry sand mold, CO₂mold, green sand mold and shell mold. 5) The higher the solidification rate was, the longer was its shrinkage pipe and the finer its grain size.

본 실험은 여름딸기 무병묘 대량증식을 위해 bioreactor배양의 증식 및 경제성 효과를 비교하고자 실시하였다. 배양방법은 반고체, 고체, 현탁배양 및 bioreactor 배양 등 4가지 방법을 이용하였다. 배양 6주 후, 식물체의 초장은 고체배양이 3.6㎝로 가장 짧았으며, bioreactor 배양이 8.3㎝로 가장 길었다. 생체중과 건물중은 bioreactor 배양이 2,261㎎과 525㎎으로 다른 배양방법에 비하여 가장 무거웠다. 액아는 반고체, 고체 및 현탁배양은 거의 발생하지 않았으나, bioreactor 배양은 주당 7개의 액아가 발생하였다. 경제성 분석 결과 기본식물 생산 시 bioreactor배양이 303원/주으로 고체배양의 845원/주보다 542원/주 적었다. 따라서 딸기 무병묘 생산시 bioreactor배양이 대량증식 및 경제적인 면에서 효율적이었다. This study was conducted to compare various culture methods and evaluate economic feasibility of each method for mass propagation of new ever-bearing strawberry ‘Goha’. Four different methods such as semi-solid culture, solid culture, liquid suspension culture and bioreactor culture were compared. The solid culture and bioreactor culture showed the shortest and longest root length, such as 3.6 ㎝ and 8.3 ㎝, respectively. Fresh weights of plants cultured in bioreactor were 2,261 ㎎, which were heavier than those of cultures. Dry weights of plants cultured in bioreactor were the heavier compared to those in other cultures. The number of axillary bud developed in bioreactor was seven, but axillary bud was not developed in other cultures. Production cost through bioreactor culture was calculated to be 303 won per plant which was 542 won less than that of solid culture. As a result, we found that the bioreactor culture was the most cost effective culture method for in vitro mass propagation in new ever-bearing strawberry ‘Goha’.

본 연구는 충북 K대학의 청년사업단 사업인 ``찾아가는 맞춤형 정서·학습 지원 서비스``의 사례이다. 서비스 대상은 전국 가구 월평균 소득 100%이하의 정서·학습지원서비스의 욕구를 가지고 있는 초등학생 가구로 충북 E군의 저소득 가정, 다문화가정, 한부모가정, 조손가정 등 신청에 의해 서비스가 이루어졌다. 2010년 4월부터 2011년 2월까지 10개월간 가정방문을 통한 정서·학습지원 서비스, 여름방학 1박 2일, 겨울방학 1일간 캠프가 진행되었다. 서비스의 이용자는 총 48명이었고, 서비스 제공기간은 총 372개월로 1인당 평균 약 8개월의 서비스가 제공되었다. 서비스 결과 첫째, 정서적 건강 증진도는 45.83%가 효과가 있었다고 보고하였다. 둘째, 학습능력 향상정도는 33.33%가 효과가 있었다고 보고하였다. 셋째, 서비스 만족도와 관련하여 본 서비스가 아동들의 눈높이에 맞춘 다양한 활동들과 학습지원이 이루어진 것에 대해 보호자 모두 만족하는 것으로 나타났다. This paper is the case study on the Customized Services for Emotional and Learning Support (CSELS). CSELS targeted low-income families, multicultural families, single-parents homes are elementary school students. From April 2010 to February 2011, about 10 months with home visits emotional and learning support programs were provided. Users of the service for 48 client. CSELS period of 372 months, average per capita was about 8 months of service provided. According to CSELS results, first, emotional health was also a 45.83% effective. Second, improving the degree of learning was an effecive 33.33%. Third, children`s eye level support tailored to the various activities and learning about what made that careers were satisfied with both.

This study analyzes the effect of clothing involvement using meta-analysis. Metal-analysis (the analysis of analyses) is widely used in various academic areas to integrate individual empirical studies and generalize the knowledge of a specific research field. Previous studies regarding clothing involvement published since 1990 were researched from the KISS database using clothing involvement and fashion involvement as a keyword; subsequently, 127 articles were identified. Studies that had insufficient statistics or included clothing involvement as a moderating (or intervening variable) were eliminated; subsequently, 36 articles provided a total of 75 data sets that were used for the final analysis. Dependent variables were grouped into 10 categories to compare the differences between high and low involvement groups. The effect size of clothing involvement was large in non-personal information source; however, it was small in utility, brand royalty and quality. In the 7 categories of relational studies that showed homogeneity, the relation size regarding conformity was smaller than the personal information source.
