  • This study was conducted to gather the baseline data on realities of experimental-practice and opinions toward spot-practice, and to examine how to cope with the problems raised at the Department of Food and Nutrition of Junior Technical College in Korea. Questionnaires were gathered from 42 chairmans of the Department of Food and Nutrition and 140 Present dieticians worked in Seoul, Bucheon am Seongnam area. The results are as follows, First, as a whole, each college had 2~3 experimental laboratory (Lab), in which Cooking Science Lab. Chemistry Lab and Microbiology Lab were occurred at higher frequency as Lab's name. Second, the numbers per experimental-practice class were more than 40 at most colleges. 85% of Present dieticians have answered to feel too much numbers per the class during their college days, whereas professors' opinions toward the numbers per class were suitable at 20~30 persons per class. Third, professors' opinion toward the adquate ratio of the theory subject classes to experimental subject classes was suitable at 60 : 40. Dieticians answered to take the theory subject classes partly or mostly on behalf of the experimental-practice classes. Fourth, the main reasons which inhibited normal experimental-practice class were the class for emphasis on examination, the shortage of experiment budget, the excess of class members, the shortage of experimental Lab Also, this results showed same propensity to present dieticians' opinion toward the same question above. Fifth, among the experimenta1-practice subjects established at the Department of Food and Nutrition, Diet Therapy Lab was highest frequency class emphasized on theory followed by Nutrition Counselling Lab, Food Processing and Storage Lab, Food Hygiene Lab and Food Microbiology Lab in that order. Here, Basic Chemistry Lab, Biochemistry Lab, Food Microbiology Lab were pointed as subjects far from the present task of dieticians. Sixth, Department of Food and Nutrition, as a whole, has conferred with spot-practice arrangement About 50% (all who want to join spot-practice) of second year students took part in spot-practice. In the other way, all colleges except for 2 colleges didn't give the credit for the spot-practice system. Seventh, according to the on analysis on spot-practice places, manufacturing company was at highest frequcney followed by hospitals, elementary school having group feeding system in that order. Especially, 16.7% (5 colleges) of the total colleges sent the students to the research institute related to food industry for spot-practice experience. Eighth, Professors' opinions toward the spot-practice time and period were preferable on summer vacation of second year and for 1~2 weeks, respectively. On the contrary, 74 dieticians answered to the adquate period as for 4 weeks. Ninth, 86 dieticians of the total 140 answered to complete the spot-practice during their college days, which helps the present task of them. Lacks of spot-practice program, Lacks of comprehension of upper personals and lacks of group feeding equipments ranks higher as difficulties in spot-practice management.

  • The use of the supernatant from a Bacillus subtilis culture mixed with sodium bicarbonate was explored as a means of controlling stem brown spot disease in dragon fruit plants. In in vitro experiments, the B. subtilis supernatant used with sodium bicarbonate showed a strong inhibition effect on the growth of the fungus, Neoscytalidium dimidiatum, the agent causing stem brown spot disease and was notably effective in preventing fungal invasion of dragon fruit plant. This combination not only directly suppressed the growth of N. dimidiatum, but also indirectly affected the development of the disease by eliciting the dragon-fruit plant's defense response. Substantial levels of the pathogenesis-related proteins, chitinase and glucanase, and the phenylpropanoid biosynthetic pathway enzymes, peroxidase and phenyl alanine ammonia-lyase, were triggered. Significant lignin deposition was also detected in treated cladodes of injured dragon fruit plants in in vivo experiments. In summary, B. subtilis supernatant combined with sodium bicarbonate protected dragon fruit plant loss through stem brown spot disease during plant development in the field through pathogenic fungal inhibition and the induction of defense response mechanisms.

  • 최근 미디어법의 변화에 따라, 방송의 규제 환경이 시장의 힘에 의해 점차 완화되고, 방송과 통신이 융합된 새로운 테크놀러지의 개발로 방송 산업이 무한 경쟁 시대로 접어들었다. 이러한 변화와 문제점을 해결하고자 최근 방송사에서는 차별화된 자사의 채널을 홍보하기 위해 새로운 채널 브랜드 아이덴티티 작업을 시도 하고 있다. 본 연구의 목적은 채널 브랜드 아이덴티티의 다양한 구성 요소(브랜드네임, 로고와 심벌, 캐릭터, 슬로건, 네트워크 디자인, 스테이션 ID)들 중에 가장 많이 제작되어 활용되고, 특히 시청자들에게 쉽게 노출되어, 접근성이 빠른 Spot Animation에 대해 분석하고, Spot Animation에 사용되는 캐릭터에 대한 확장성과 그 유용성을 검토하여 시청자의 채널인지도와 채널 충성도를 높일 수 있는 캐릭터를 기획하고 관리 하는데 있다. 구체적으로 KBS와 MBC 각 방송사를 대표하는 각각의 캐릭터의 탄생 배경과 제작 및 활용을 알아보고 두 방송사의 Spot animation에 등장하는 각 캐릭터의 형태, 색상, 재질, 표현 등을 비교하여 특성을 정리한다. 결론으로, KBS와 MBC의 세 가지 캐릭터는 전문적이고 체계적인 기획과 관리가 적용되지 못하였고, ID의 Spot animation에서 각 채널이 추구하는 이미지만을 표현했을 뿐, 캐릭터로서의 다양한 확장성과 넓은 유용성을 충분히 관철하지 못했다는 문제점을 가지고 있다. 방송사의 채널 브랜드 가치를 높이는 가장 중요한 요소는 차별화된 아이덴티티를 가지는 것이고, 그 핵심에는 채널의 이미지를 담당하는 스테이션 ID를 효과적으로 만드는데 있다. 따라서 시청자에게 가장 많이 노출되고 쉽게 접근할 수 있는 ID의 Spot animation과 캐릭터는 매우 중요한 요소로서, 방송사를 대표하는 캐릭터는 초기 기획과 제작에 이르기까지 전문적인 연구와 체계적인 관리가 필요하다.

  • 본 연구는 새로운 정보에 대하여 국채선도금리시장(forward market)과 국채 현물시장(spot market) 중 어느 시장이 더 효율적으로 반응하는지에 관한 분석을 실시하였다. 2002년 3월부터 2005년 1월말까지 3개월, 6개월, 9개월 및 1년물 국채선도금리(forward rate)와 각 시계열들의 현물 금리의 수익률 및 변동성자료를 사용하여 그랜져인과관계분석, 충격반응함수 및 분산분해 분석을 실시하였으며 주요 분석결과는 다음과 같다. 먼저 수익률 및 변동성을 이용한 그랜져인과관계분석(Granger causality test)결과에 의하면 국채 선도금리시장이 국채현물시장보다 새로운 정보에 대하여 더 효율적으로 반응하는 것으로 나타났다. 충격 반응함수(impulse response analysis)에서도 국채선도금리시장의 국채현물시장에 대한 영향력이 국채현물시장의 국채선도금리시장에 대한 영향력보다 더 강하고 지속적인 것으로 나타났다. 분산분해분석(variance decomposition analysis)에서는 전체적으로 3개월 및 6개월 등기간이 짧은 국채선도금리 수익률 및 변동성이 기간이 긴 국채선도금리보다 국채현물시장에 대한 영향력이 상대적으로 더 큰 것으로 나타났다. 이러한 분석결과로부터 새로운 정보에 대하여 국채현물시장보다는 국채선도금리시장이 더 효율적으로 반응하고 있음을 추론해 볼 수 있으며 이는 기존 국내외 주식현물시장과 선물시장들 간의 영향력을 분석한 결과 선물시장의 현물시장에 대한 영향력이 더 강한다는 결과들과 일맥상통하는 것으로 나타났다.
