Objective: The purpose of this study is to provide basic data in order to increase the flourish of early childhood pre-service teachers by examining pre-service teacher's basic psychological needs and characteristics on flourish. Methods: A questionnaire survey was conducted on 200 pre-service teachers majoring in early childhood education in Busan and the results were analyzed. Results: First, the level of basic psychological needs, characteristics and flourish of pre-service teachers was above average and there was a significant positive correlation between basic psychological needs, characteristics and flourish. Second, the characteristics of pre-service teachers were relatively more influential on flourish than basic psychological needs. Conclusion/Implications: The main variables predicting early childhood pre-service teacher's flourish are characteristics and basic psychological needs. And as characteristics and basic psychological needs of pre-service teachers are promoted, the flourish of pre-service teachers is increased.

Eucalyptus pellita is one of the fast-growing tree species and has become predominant in Indonesian forest plantations. Meanwhile, tree breeding programs with clone development are the best way to provide greater genetic advantages. A better understanding of genetic control on growth and basic density in E. pellita is important for increasing wood productivity and quality. In this study, growth characteristics (tree height, diameter, and volume), basic density and its genetic parameters (heritability, genetic gain and genetic correlation) were determined. The number of clones tested in both trials was 50, divided into 5 blocks, and 5 trees/plot. The results showed that there were significant differences in growth and basic density among clones. There was an interaction between genetics and the environment further indicating the existence of unstable clones. The high heritability was found in tree height (0.82-0.86), diameter (0.82-0.90), and basic density (0.91-0.93). This implies that E. pellita has good opportunities for genetic improvement to increase wood productivity and quality. In addition, the results of genetic correlations among growth characteristics (height, diameter, and volume) and basic density showed positive moderate to highly significant value. It is suggested that these characters may be used to the advantage of the breeder for bringing improvement in these traits simultaneously. Therefore, this study provides important information of the genetic improvement of wood quality in E. pellita in Indonesia.

Living infrastructure facilities are concentrated in cities with high population density, it is necessary to supply basic living infrastructure facilities to promote welfare in rural areas. The establishment of basic living infrastructure is the minimum right for daily living of local residents. It is supplied by considering national economic and social characteristics through national minimum standards, but it is limited to be practically applied to rural areas where many villages are dispersed in large areas. There is a situation. Therefore, it is necessary to supply systematic and quantitative facilities by analyzing villages that do not meet the minimum standards of basic living infrastructure in rural areas and by considering their characteristics. The purpose of this study is to identify the basic living infrastructure facilities of village units and analyze the characteristics of each village for Boeun-gun, Chungcheongbuk-do.

A spot-size converted Fabry-Perot laser diode (LD) was flip-chip bonded to a silica-terraced planar lightwave circuit(PLC) platform to examine the effect of the silica terrace on the heat dissipation of the LD module. From the measurement of the light-current characteristics, it was discovered that the silica terrace itself is not a strong thermal barrier, but the encapsulation of the integrated LD with an index-matching polymer resin more or less deteriorates the heat dissipation.

제주도 여러 도로현장에서 송이(화산쇄설물)는 빈번하게 접하는 토목재료이다. 송이는 일반적으로 파쇄성이 크고, 입자가 큰 재료로 알려져 있을 뿐, 이 화산쇄설물에 대한 연구가 미미하여 이 송이에 대한 처리방법에 많은 어려운 점이 따르고 있다. 본 연구에서는 제주도 각 지역에서 채취한 송이의 기본적인 강도특성에 관하여 연구하였다. 연구결과로 구한 송이의 강도특성 값은 추후 도로, 옹벽, 사면 등의 각종 설계 시 기본적인 자료로써 적용되어 질 수 있을 것이다.

기초학력의 부진은 교과 학습 및 사회생활의 장애요인으로 작용한다. 국가적 차원에서는 2002년부터 실시된 '초등학교 3학년 기초학력 진단평가'와 '학습부진학생 책임지도제', 보정교육 자료 개발 등 교육의 복지를 실현하고자 일련의 노력을 기울이고 있다. 기초학력 진단평가의 목적은 학습 결손 원인에 대한 정보 및 개인적 정보를 수집하여 이들을 지도하는데 도움을 주기 위한 것이다. 본 논문에서는 상담기간 축적된 기초학력 진단평가 결과 나타난 미도달 학생들이 특징을 분석하였다. 미도달 학생들은 문항에 포함된 수치적 특징, 받아올림/내림의 여부, 문항의 배치 및 진술 방식, 정보 제시 방식, 개념의 전형적인 예, 친숙도, 일상생활에서의 사용 빈도 등에 상당한 영향을 받는 것으로 나타났다. 본 연구의 결과는 미도달 학생들의 지도 및 보정교육 자료 개발을 위한 근거를 마련해줄 수 있을 것이다.

The effects of ZnS insertion on the characteristics of CaS:Pb phosphor were investigated. The intensity of photoluminescence of ZnS inserted CaS:Pb excited by 347nm were increased while that excited by 254nm was unchanged, compared to those of CaS:Pb thin film. The electroluminescent display having ZnS inserted CaS:Pb showed lower threshold voltage and higher efficiency than those of CaS:Pb ELD device.
