NIE를 활용한 환경 글쓰기 교육프로그램이 초등학생의 환경소양에 미치는 영향
이상원,이영희 한국실과교육연구학회 2010 實科敎育硏究 Vol.16 No.4
본 연구는 초등학생 4학년을 대상으로 NIE를 활용한 환경 글쓰기 교육이 초등학생의 환경소양에 대한 교육적 의미와 효과를 검증하고자 하였다. 이를 위하여 본 연구와 관련된 제7차 교육과정과 선행연구의 고찰을 통하여 NIE를 활용한 환경 글쓰기 교수·학습 모형 및 프로그램을 개발하여 학습현장에 적용하였다. NIE를 활용한 환경 글쓰기 프로그램의 효과를 검증하기 위하여 사용된 검사지는 진옥화(2004)가 개발한 환경소양 측정도구 86문항을 초등학교 수준에 맞게 수정·보완한 최혜란과 이상원(2009)의 것을 재구성하였으며, 연구과정에서 얻어진 정량적 자료는 SPSS 17.0 통계 프로그램을 이용하여 분석하였다. 그리고 정량적 결과를 보완하기 위하여 연구자의 관찰·기록과 수시 면담 및 포트폴리오 수집을 통해 정성적 분석이 이루어졌다. 본 연구를 통하여 NIE를 활용한 환경 글쓰기 교육은 초등학생 환경소양의 4개의 환경 목적 수준별 모든 영역에 긍정적 영향을 미친다는 결과를 얻었다. 이는 NIE를 활용한 환경 글쓰기 프로그램이 새로운 환경교육의 방법으로서 그 의미가 크다고 할 수 있을 뿐만 아니라 NIE를 활용한 환경 글쓰기 교육이 초등학생들의 인지적 수준을 고려하여 프로그램이 개발한다면 초등학생들에게 환경소양을 함양시키는데 기여를 할 것으로 기대된다. 따라서 환경 글쓰기 교육과 관련된 심층적인 연구와 보다 체계적인 교수·학습 활동에 대한 후속 연구가 필요할 것으로 사료된다. This study is an experimental study to investigate the influences of the environmental writing education program through NIE on environmental literacy of fourth grades in an elementary school. The results of this study are as follows. First, the researcher was able to develop and apply professor·learning model for the environmental writing education through NIE by abstracting environmental education contents for the second semester of the 4th grade in 7th curriculum. Second, applying the environmental writing education through NIE had an positive effect on elementary school students' environmental literacy. Third, applying the environmental writing education through NIE had an positive effect on the every elements of environmental literacy divided by the four goal levels of the environment education. Fourth, the result of a case analysis of observation and interview, many students had an interest in the environment, and showed attitude change, will to act and change of action while participating in the environmental writing education through NIE. In conclusion, the environmental writing education through NIE can apply to the elementary schools, and has a positive effect on the cultivation of environmental literacy of 4th grade students. That is to say, this program is meaningful as a new environmental education methods, and it is necessary to research more intensively and systematically on the professor·learning activities related to the environmental writing education.

본 연구는 2009년 9월부터 2014년 9월까지의 기간 동안 KRX SRI지수로 편입되는 기업과 제외되는 기업을 대상으로 사건연구방법을 통해 SRI지수 편입 및 제외와 기업가치(주식가치)의 관계를 분석한다. 본 연구의 주요 분석결과는 다음과 같다. 첫째 , 비정상수익률의 경우 SRI편입과 제외 사건 모두에서 유의하지 않았으나 누적초과수익률의 경우 편입 시에는 지속적인 일별 증가 패턴을 보였으며 제외 시에는 일별 하락 패턴을 보이고 대부분 유의하게 나타났다. 둘째, 비정상거래량에 대한 분석 결과 SRI편입과 제외에서 변경 발표일 전후에서 약하게 유의한 양(+)의 효과가 나타났으며 누적초과거래량의 경우 변경발표일 이후 강한 양(+)의 효과가 나타났다. 셋째, 변동성 영향을 분석을 위해 비조정변동성비율과 시장조정변동성비율에서 두 사건에서 유의한 강한 양(+)의 영향이 있는 것으로 나타났다 또한 변경일 이후 변동성이 증가한 종목의 비율도 증가한 것으로 나타났다. 따라서 기업의 사회적 활동지표인 SRI지수 편입 및 제외사건과 기업의 가치 간에는 서로 정의 관계가 있음 This study empirically analyses the effects on the value of firms when stocks added to and deleted from KRX SRI Index in Korea. This analysis targets the companies that has been added to or deleted from the KRX SRI index during the period of Sep. 2009 to Sep. 2014. the main results of the analysis are as follows. First, the analysis of average abnormal return do not show significant results in both the addition case and the deletion case. The analysis of the cumulative abnormal return shows the continued daily increase pattern in the case of addition and the continued daily decline pattern in the case of deletion and shows almost statistically significant results. the change of return by the announcements of change events became larger than the change events themselves. Second, before and after the days of the announcement, the analysis of abnormal trading volume shows the statistically significant and positive effect in commonly the addition and the deletion. Also, the cumulative abnormal trading volume shows a strong positive effect in both of addition and deletion after the day revealed. Third, the analysis of volatility shows the statistically significant strong positive effect on non-adjusted ratio of volatility and market-adjusted ratio of volatility in all the observation interval into two cases. Also, it shows that the proportion of stocks that the volatility has increased after the event date became larger. Thus, when viewed as a whole, it can be inferred that the event of addition into and deletion from SRI index and financial value of the firm have a relation of positive. the non-financial factors such as social activities of firm can also be inferred that has the potential as an investment indicator.

We report the preparation of iron-oxide nanoparticles and their characterizations by using Mossbauer spectroscopy and high resolution transmission electron microscopy (HRTEM). The Mossbauer measurements were essential because x-ray diractometer (XRD) alone should not distinguish between magnetite, maghemite, and spinel oxides because their crystal structures are similar.Our iron-oxide nanoparticles showed a superparamagnetic behavior at room temperature, and the HRTEM measurements conrmed two narrow particles size distributions are with an average of 4 nm and the other with an average of 6 nm for our magnetite nanoparticles. The crystal structure of samples was characterized by using XRD, and the magnetite and the maghemite phase were easily distinguished by using Mossbauer spectroscopy. At 4.2 K, Mossbauer spectra had the typical sextet shapes, indicating ferrimagnetic behaviors, for the 4 nm and 6 nm iron oxide nanoparticles. For these samples, the 4.2 K spectrum was tted using three magnetic components of hyperne elds Hhf = 529, 509 and 466 kOe, isomer shifts = 0.40, 0.30 and 0.78 mm/s corresponding to Fe3+ions at site A and Fe3+ and Fe2+ ions at site B for 4 nm, and Hhf = 529, 507 and 472 kOe, isomer shifts = 0.40, 0.30 and 0.72 mm/s corresponding to Fe3+ ions at site A and Fe3+ and Fe2+ ions at site B for 6 nm, respectively. The saturation magnetization MS were 59.5 emu/g for 4 nm and 59.7 emu/g for 6 nm at room temperature (295 K) under an applied eld of 10 kOe. These samples will be used to candidate for biomedicine applications as magnetic carriers.

이상원,이철준 한국잠사학회 1969 한국잠사곤충학회지 Vol.10 No.-
There are two fold aims in this experimental study. The aim is to investigate the bacteria which produce the high activity enzyme or the cocoon for utilization to the textile and the industry. The ether is to protect against the bacteria that damage silk protein during storage. The results are summarized as followes: 1. Among the isolated bacteria from the cocoon, No 4 strain had the high activity of the $\alpha$-amylase. But this strain had not been identified. The results of experiment is shown in the table II. 2. Among the isolated bacteria from the cocoon, No II strain had the high activity of the protease on substance of the casein. The results of the experiment is shown in the table II. 3. The bacteria which had the high activity of the degumming effect of the sericin, the part of the operation for 7 days was higher part of the operation for 3 days. The results of the experiment are indicated in Fig I and Fig II.
