현재의 ICT 활용 교육은 소양 교육에 초점을 두고 단순히 정보통신의 기능을 습득하는 기술적인 면에 치우치는 문제점을 가지고 있다. 본 연구에서는 이와 같은 문제점을 해결한 ICT 활용 교수-학습 모형을 제안한다. 제안된 모형은 기존의 교수-학습 유형별 ICT 활용 모형들에 대해 정보활용의 실천력을 조사하고 분석한 다음, 이를 평가할 수 있는 질적 기준이 교수-학습 모형에 균형있게 반영되도록 하였다. 적용 결과, 정보 활용의 실천력을 질적으로 평가해 주는 6개 항목 중 5개 항목에서 유의미한 향상이 있음을 보였다. The present instruction using ICT has a problem that it inclines toward instructing the simple technique of information or communication technology. In this paper, to cope with this problem, we propose a new Teaching-Learning model using ICT. The previous teaching-learning models using ICT are investigated and analyzed. Then, the criteria for evaluating the ability to put information literacy into practice are evenly reflected in the proposed model. is evenly reflected. The result of experiment reveals that the proposed model enhances the ability to put information literacy into practice on 5 items of 6 qualitative evaluation criteria.

Generating rate of food waste in Korea is relatively high as 11,793ton/day corresponding 26.5% of municipal solid waste(USA 25%, England 19% and Germany 28%). Food waste is now separated from other solid wastes by solid waste management law and efforts of NGO. Thus, there is a need to develop effective and efficient technologies of food waste treatment. In this study, vermicomposting was applied to food waste mixed with sludges from a pulp and paper industry. Lumbricus rubellus grew and reproduced favorably in mixtures of organic sludge containing up to 70% of food waste. The casting was rich in nitrogen and phosphorus with 19.9 ~ 20.6 of C/N ratio.

In order to seek optimum conditions for ZSM-5 formation in the absence of organic template,the effects of both starting composition and water glass as silica source were examined. Water glass was most inexpensive among silica sources, but this was difficulty in reactant control because of contained much alkali ingredient, Considering environmental problem and economic performance,chose alkali drawing-out method to use methanol newly to remove alkali ingredient of waterglass. Characterization of ZSM-5 was carried out by means of XRD, SEM.

This paper presents ferroelectric Pb(Zr_0.52Ti_0.48)O_3 (PZT) thin film by sol-gel synthesis with metal-organic precursors. Sol-gel reaction sequences with metal-organic precursors were confirmed through DTA and FT-IR measurements and perovskite phase formation was investigated by rapid thermal annealing technique. The structural and morphological properties of PZT thin film were investigated by XRD and SEM. Perovskite phase PZT single phase was appeared at temperature of 650 ℃ and the second phase, pyrochlore, was decreased as increasing the annealing temperature, which was clearly indicated by investigating the size of 'rosette structure' and pyrochlore phases at different annealing temperatures. The P-E loop measurement indicated the relation of the applied voltage vs. domain alignments in the PZT thin film system.

The purpose of this study is to determine how a Taekwondo player's athletic satisfaction affects his/her psychological health and overall personal happiness. A questionnaire survey was carried out on a sample group of 200 students attending colleges located in Seoul and Gyeonggi Province. Then, 23 questionaries deemed not trustworthy were eliminated, leaving 178 questionaries for analysis. The questionnaire, which contained total 128 questions, showed the confidence level falling between .5241 and .8945 (Cronbach's alpha). The study, which relied on frequency analysis, t-test, One-way ANOVA, and Scheffe test, produced the following results. First, athletic satisfaction showed a statistically significant difference (5% range) depending on sex, school year or athletic experience. Second, psychological health resulted in a statistically significant difference (5% range) depending on sex or athletic experience while no difference was noticed regarding school year. Third, happiness in life showed a statistically significant difference (5% range) depending on sex or school year while no difference was noticed with regard to athletic experience.

Effects of various types of salts (commercial low salt, sea salt, refined salt, and bamboo salt) and concentrations (0, 3.0 and 5.0%) on the growth of yeasts isolated from Kimchi were investigated. The isolated yeasts used in the study are as follows: Saccharomyces cerevisiae. Sporobolomyces albo-rubescens, Issatchenkia orientalis, Cryptococcus luteolous, Ustilago maydis. Candida humilis, Pichia onychis, Cadida nitratophila, and Pichia jadinii. The growths of the yeasts were inhibited against each salt concentration. The growths of Candida sp. isolated from the later stage of fermentation was strongly inhibited against 5% concentration of salt. On the other hand the induction phase of Issatchenkia orientalis isolated at the early stage of fermentation was the quickest among all the tested yeasts. Among the salts. bamoo salt was found to be strongest inhibitor of, the growth of yeasts.
