This study investigated the relationship between the ecological literacy and the sense of happiness of child day care teachers. One hundred twenty -five child care teachers in the Incheon and Kyunggi areas were participated in this study. Data responses from day care teachers were analyzed sing SPSS 17. The results were as follows. First, generally, there was a significant difference in ecological literacy depending on child day care teachers' carre, experiences in early childhood, and in-service teacher program. However, there was no difference in ecological literacy except in ecological literacy attitude depending on child day care teachers' academic area. Second, there was a correlations between the ecological literacy and the sense of happiness of child day care teachers. This study will provide basic information to better understand the relationship between the ecological literacy and the sense of happiness of child day care teachers.

This study describes the radiolytic fabrication of large Pt nanoparticles (NPs)-decorated reduced graphene oxide (L-Pt/rGO) and its use as a counter electrode (CE) in dye-sensitized solar cells (DSSCs). A homogenous aqueous solution of GO in 10 wt% isopropyl alcohol (IPA) aqueous solution containing Pt precursor was irradiated with γ-ray at room temperature to prepare the L-Pt/rGO. The analytic results from TEM, EDX, XPS, and Raman revealed that the rGO decorated with 100 nm Pt NPs was successfully formed by the γ-ray irradiation-induced reduction of both the GO and Pt precursor in aqueous IPA solution. Based on the results of the DSSCs performance test, the energy conversion efficiency of the DSSCs with the L-Pt/rGO-based CE outperformed that with the rGO-based one due to the lower sheet resistance, and even was comparable to that of the Pt-based CE. This L-Pt/rGO fabricated by a simple, room temperature and scalable radiolytic method can be used as a promising CE material for low-cost and high-performance DSSCs.

To research the changes of Ramyun in Korea, this paper was went over an historical study through the content analysis of ads. from 1963 to 2012. The study period was divided into 6 stages based on GNI(Gross National Income). The advertisements were classified into new advertisements and all ones, and the advertisements of new Ramyun were categorized with 4 ways. And the most emphasized messages of advertisements and advertising models of each periods were also examined. The total number of new advertisements was 185(3.7/y) and 650 total advertisements(13.7/year). The most emphasized messages were changed from ‘taste’ and ‘high calorie’ to ‘noodles’, ‘function(specific nutrition)’. The advertising models were actors, comedians, popular singers, in turn. The 1960's was the period when the fewest new products were advertised to consumers most often. 1980-1996 was the period when the most new products were advertised the most. During the depresseions, all ads were more frequently and new ads were lower advertised. Above results, each period was named as follow, respectively ; the Expansion period(1963~1969), the Set-up period(1970~1979), the Competition period (1980~1987), the Bipolarization period(1988~1997), the Transition period(1998~2003), the Stabilization period(2004~2012). 본 연구의 목적은 한국에서 라면 출시 이래 변화 양상을 광고 내용 분석을 통해 통시적 관점으로 분석하는 것이다. 조사대상 기간(1963~2912년)을 6개 시대로 분류하였고 신문게재 광고를 중심으로 신제품과 전체제품 광고로 분류하여 총건수 및 평균건수를 구하였다. 신제품에 한해 면 제조법, 제품 형태, 요리 형태, 스프 주재로 등으로 분류하여 형태 변화를 분석하였고 광고에서 강조된 메시지와 모델 변화를 시대별로 알아보았다. 신제품은 185건(3.7건/년), 전체제품 650건(13.7건/년)이었다. 유탕면/건면/생면은 88:6:6%, 봉지면/용기면은 76:24%, 탕면/비빔면은 81:19%, 스프 주재료는 소:기타:해물:닭이 55:21:16:8%이었다. 강조 메시지는 초기에는 맛과 높은 칼로리(영양)에서 후기로 갈수록 면, 맛, 기능성(구체적 영양)로 변화하였다. 광고모델은 배우, 코메디언, 가수, 스포츠선수, 일반인, 전문인 순이었으며 후기로 갈수록 모델이 젊어지고 자주 교체되는 경향을 보였다. ‘60년대는 적은 신제품을 가장 자주 소비자에게 노출되었고 ’80~‘96년은 가장 많은 신제품이 나왔으며 ’98년~‘12년은 신제품, 전체제품모두 자주 광고된 것으로 나타났다. 이상을 바탕으로 1기는 팽창기, 2기는 정착기, 3기는 경쟁기, 4기는 양극화기, 5기는 전환기, 6기는 안정기로 명명하였다. 본 연구는 객관적 자료를 통해 국내 라면사를 사회적 특징과 연결지어 실증적 분석을 했다는 데에 의의가 있으며 라면 연구의 학문적 기초자료 및 향후 라면 업계의 예측자료와 전략 수립에 활용될 수 있으리라 본다.

This study aimed at exploring how an instructor constructs meanings through content-based instruction (CBI) offered to pre-service teachers majoring in early childhood education. The course, early childhood mathematics education, was conducted during the spring semester in 2011. This study adopted a narrative inquiry, and data were collected through observations, interviews, and work samples. This study found that during the whole process from the preparation phase to the end-of-program evaluation,the instructor captured diverse challenging moments. During the preparation phase, she needed to have careful orchestration in designing lessons in order to overcome her feeling of pressure as a non-native speaker of English and design the integration of contents and English language learning to be truly powerful. In the phase of implementation, the lack of student motivation and building a good rapport between the instructor and the students were certainly challenges. The result of the student evaluations weakened her desire to implement CBI. The instructor incorporated diverse instructional strategies to overcome the obstacles. The instructor’s experiences in this study will positively shape future educators’ thinking and learning about meaningful and appropriate academic English instruction for content-area teaching of college students who were majoring in early childhood education.
