장정균,정진현 한국실과교육학회 2014 한국실과교육학회지 Vol.27 No.4

The purpose of this study was to identify the effect of children's invention attitude and mental health through invention education in elementary school. Students who participated in the experiment were 40 students from two 6th grade classes in N Elementary School located in D City. Subjects were 20 students for experimental group and 20 students for comparative group. Total 20 times of the invention education were conducted on the experimental group. Questionnaire in this study used invention attitude and Symptom Checklist-90-Revision(SCL-90-R). SPSSWIN program was used for data analysis, and t-test were conducted to identify the difference between invention attitude invention and mental health of experimental group and comparative group before and after the experiment treatment. Also, Pearson correlation analysis was conducted to investigate the relationship between invention attitude and mental health. The main results of this study were as follows:First, it was identified that experiencing the invention education makes positive effect in improving attitude of elementary school students towards invention. Second, the invention education makes positive effect on mental health of elementary school students. Third, as a result of analyzing correlation between the invention attitude and mental health of elementary school students through invention education, the correlation coefficient between factors of invention attitude and mental health condition showed significantly positive correlation that the higher invention attitude showed higher mental health points. Therefore, it was made positive effect in improving students' attitude towards invention and in formation of desirable mental health. 본 연구의 목적은 초등학교 발명교육이 아동의 발명태도와 정신건강에 미치는 영향을 검증하는데 있다. 연구 대상은 D시의 N초등학교 6학년 40명 중 실험집단 20명, 비교집단 20명이다. 발명교육 프로그램을 개발하여, 실험집단을 대상으로 총 20차시의 발명교육을 실시하였다. 검사 도구는 발명태도와 간이정신진단 검사지를 사용하였다. 자료 분석에는 SPSSWIN 프로그램을 사용하였고, 실험처치 전⋅후 실험집단과 비교집단의 발명태도와 정신건강의 차이를 검증하기 위하여 t-검증을 실시하였다. 또한 발명태도와 정신건강과의 관계를 살펴보기 위해 Pearson 상관분석을 실시하였다. 본 연구를 통하여 얻어진 주요 연구 결과는 다음과 같다. 첫째, 발명교육의 경험은 초등학교 아동들의 발명에 대한 태도 수준을 높이는데 긍정적인 효과가 있는 것으로 나타났다. 둘째, 발명교육의 경험은 초등학교 아동들의 정신건강의 증진에 긍정적인 영향을 미치는 것으로 나타났다. 셋째, 발명교육에 따른 발명교육과 정신건강 사이의 상관관계를 분석해 본 결과, 초등 아동의 발명태도가 높을수록 정신건강 수준이 높은 것으로 나타났다. 따라서 초등학교 발명교육이 아동의 발명태도와 정신건강 향상에 긍정적인 영향을 미쳤음을 알 수 있다.

The purpose of this study is to analyze consumption of homemade organically processed food (HOPF), and to derive directions for consumption promotion of HOPF. A survey was conducted for quantitative analysis regarding consumption. This study used an Ordinal Logistic Regression Model to derive more significant results in analyzing factors of consumption. The findings was that younger consumers with high income are more likely to purchase HOPF. And those consumers with high price and quality contentment are more likely to purchase HOPF. And contentment with certification institutions and improvement of health have a significant positive relationship with consumption. Consumers were found to pay 51 percent more for HOPF than for non-HOPF products. This level show that the current level of price premium for HOPF is 51 percent higher than their desired level. In order to reduce the price premium for HOPF, effective policy programs should be developed. A targeted market strategy to sell HOPF to younger consumers with high income is needed to boost consumption. A strict certification management system should be established to enhance consumer reliability in HOPF.

The objective of this paper is to analyze management performance of organic farming management organizations in the large-scale environment-friendly agricultural districts, focusing on cases of organic farming organizations in Chungnam Asan city and Gyeongnam Sancheong-gun which are leading regions in Korean organic agriculture. The management performance in Asan Organic Farming Organization showed that ratio of operating gain to revenue in 2008~2009 increased by 1.2% point compared to in 2006~2007. The management performance in Sancheong Organic Farming Organization showed revenue gain by KRW 2 million in 2009 whereas it suffered a loss by KRW 24 million in 2008. The management performances implied that the amount of financial performance was not yet large and would be a symbol for soundly developing organic farming organization. This paper suggested that network system, recycling agriculture, and the enlargement of processing industry would be very useful to maximize synergy effect in organic farming organizations in a large-scale environment-friendly agricultural districts.

The purpose of this study is to systematically analyze the consumer purchasing behaviors and future consumption towards homemade organically processed food(HOPF), and to derive directions for consumption promotion of HOPF. To this end, a survey was conducted for quantitative analyses regarding consumer purchasing behaviors and future consumption. This study used Ordinal Logistic Regression Model to derive more significant results in analyzing factors of future consumption. The analytical results were used to derive policy directions aimed at boosting the HOPF consumption. The consumer survey was conducted for 503 housewives living in Seoul and Gyeonggi Provinces using online. Among the respondents(400 housewives who have purchased HOPF) those in their 30s amounted to 40(10.5 percent), followed by those in their 40s with 182(45.5 percent), and those in their 50s or above with 178(44.5 percent). From the income perspective, 52.0 percent of the respondents were 3million won to 4million won. Among the respondents(103 housewives who have not purchased HOPF) those in their 30s to 40s amounted to 70.9 percent. From the income perspective, 58.3 percent of the respondents were 3million won to 4million won. The consumer survey conducted regarding certification mark and additives sign has found that the majority of domestic consumers confirm those. In detail 72.8 percent of those responded said that “I confirm certification mark while buying HOPF.” And 67.8 percent of those responded said that “I confirm additives sign while buying HOPF.” In relation to the future consumption toward HOPF, the Ordinal Logistic Regression Model was applied for analysis. The findings was that the younger consumers with high income are more likely to purchase HOPF. And those consumers who recognize the price and quality contentment to be high are more likely to purchase HOPF. And the contentment of certification instrument and improvement of health have a significant plus relationship with future consumption. The consumer survey conducted regarding consumption promotion has found that price reduction, reliability improvement, and store expansion are needed to promote consumption. Consumers who have purchased HOPF were found to pay 51 percent more for it. This level show that the current level of price premium for HOPF is 51 percent higher than their desired level. The consumer survey conducted regarding improvement of health has found that 48.8 percent of those responded said that "HOPF is helpful to family health. In order to reduce price premium for the HOPF effective policy programs should be developed. The target market strategy to sell HOPF to the younger consumers with high income is needed to boost consumption. To expand consumption, it is necessary to strengthen promotional efforts. The strict certification management system should be established to enhance consumer reliability in the food.

The BOES (BOAO Echelle Spectrograph), a fiber-fed echelle spectrograph of the BOAO 1.8 m telescope, has been designed and now is being manufactured. The BOES follows a white pupil design collimated with two off-axis parabolic mirrors. The 136mm collimating beam leaving the 41.59 grooves/mm R4 echelle grating is refocused near the narrow folding mirror. Through the two cross-disperser prisms and $\phi250 mm(f/1.5)$ transmission camera, the beam images on EEV $2k\times4k$ CCD. The BOES can take the wavelength range of 3700 to $10100{\AA}$ at a single spot with spectral resolution R = 20000 to 40000 depending on the fiber set employed. We describe the key sciences and performance, current status of construction, and future plan of the BOES.
