To assess the health risk for benzo(a)pyrene by the intake of edible oils, 288 cases of edible oilscollected from food markets were analysed using the high performance liquid chromatography with fluorescencedetector. The levels of benzo(a)pyrene were from non-detection to 4.78 μg/kg, and the average was 0.11 μg/kg. Thechronic daily exposures of benzo(a)pyrene for total population group and consumer-only group were estimated usingthe food consumption data in the fifth Korea National Health and Nutrition Examination Survey in 2011. The estimateddaily intake of benzo(a)pyrene was 4.26 × 10−3 ng/kg b.w./day for total population group and 7.64 × 10−3 ng/kgb.w./day for consumer-only group. The MOE (margin of exposure) of benzo(a)pyrene for total population group andconsumer-only group was 7.28 × 107~1.74 × 108 and 3.95 × 107~9.42 × 107, respectively. Accordingly, the health riskfrom benzo(a)pyrene caused by the intake of edible oils was considered as a very low level.

In this study, HPLC-RI was used to determine sugars and sugar alcohols contents in 102 differentkinds of processed foods met to children's taste. The average amount of sugars per 100 g of candies was 70.25 g, ofprocessed cocoa products was 65.34 g, of processed chocolate products was 47.53 g, of breads was 25.66 g, of cookieswas 22.28 g, of ices was 12.47 g, of snacks was 9.74 g. Processed cocoa product items had relatively higher sucrosecontents (56.80 g/100 g) than any other items. The average amount of sucrose per 100 g of candies was 44.20 g, ofprocessed chocolate products was 32.89 g, of breads was 23.11 g. When the contents of sugars in processed foods metto children's taste per on serving size were compared to WHO guidelines, the percentages were 5.84~28.52 about recommendeddaily intake of total sugar of 50 g. The result for the analysis of confectioneries showed that 13 samples of102 were detected and the sugar alcohols content of samples investigated varied between 0.01~15.06%.

사이버 영재교육의 가능성 탐구를 위한 사례 연구 : A Case Study
강숙희,조석희,금미라 한국교육정보방송학회 2000 교육정보미디어연구 Vol.6 No.1
정보화사회에 능동적으로 대응할 수 있는 영재교육의 필요성이 제기되고 있다. 그러한 필요성을 충족시켜줄 수 있는 방안의 하나는 인터넷을 이용한 사이버 영재교육이라고 할 수 있다. 그러나, 아직까지 사이버 영재교육은 그리 활성화되고 있지 않다. 이에 따라 사이버 영재교육이 과연 가능한가에 대한 깊이 있는 탐색이 요구되고 있다. 본 연구는 한국교육개발원의 '사이버 영재교육연구원'의 사례를 분석해보았다. 이 시스템은 초등학생을 대상으로 하는 국내 최초의 사이버 영재교육 시스템이라는 데 그 의의가 있다. 이 시스템의 시범운영 현황 및 프로그램 평가를 통해 보다 전문적이고 체계적인 사이버 영재교육을 제공하기 위한 시사점을 모색해보았다. 그 결과, 전국에 있는 초등학교 영재아 동들이 이 프로그램을 통해 장소나 시간에 구애없이 학습하였고, 깊이 있는 탐구 중심의 영재교육에 참여하고 있는 것으로 나타났다. 그러나 영재교육이 일반교육과는 달리 학습자의 질문에 대한 상세한 답변, 개별적인 상담 등 전문적인 관리가 각별히 요구되는 점, 프로젝트를 수행하여 산출물을 내는 점, 학습이 단계적으로 이루어지는 점 등은 사이버 영재교육을 실시 및 운영함에 있어 새로운 해결방안이 제시되어야 할 부분임이 확인되었다. The need for gifted education is growing as our society has turned into the knowledge-based society. One way of meeting such need is to use the Internet for gifted education. However, cyber gifted education is only at the beginning stage. In this context, this research is conducted to find out the plausibility of cyber gifted education. For that purpose, one example of cyber gifted education system was analyzed focusing on the problems related to the operation and management of the system as well as the evaluation of the courseware and services provided by the system. As a result, it was found that the users of the system were distributed all over the nation and that effective learning occurred from the uses of the system regardless of time and place. It was also learned that caution needs to be taken in operating cyber gifted education programs so that each different needs of each individual user should be met by the program while accomplishing the overall goals set by the program.
