The goal of today's environmental education is to enhance the understanding of the serious of environmental problems and the interactions among environment. With this perspectives people need to be aware that environmental education is no longer a liberal arts in university education, but play a vital role within the socio-cultural context. This study was performed to assess the changes in the university student's attitudes and consciousness in real life after the education of a point at issues of environmental problems. For this study 11 questionnaires which were composed of large scale environmental problems(water and air pollution), and small scale environmental problems(food additives, GMO, endocrine disrupter) were performed with self-administered by university students(n=781) who made a application for liberal arts related to environmental subjects. According to the analysis the most student's consciousness of a point at issue of environmental problems(water pollution, air pollution, additives, GMO, endocrine disrupter), and practical attitudes(i.e., practical attendant at congregation and internet voting) were change statistically significant(p<0.01) after the education of a point at issue of environmental problems rather than before. Specially, the score for the item of the large scale problem of environmental issues(water pollution, air pollution) were decreased significantly(p<0.01), but the score for the small scale problems, such as food additives, GMO, endocrine disrupter were increased significantly(p<0.01) after the education of a point at issue of environmental problems(p<0.01). And among the students that participated, 97.7% responded that such a point at issues of environmental problem is needed at the university. With this educational improvements supports the states that the education of a point at issue of environmental problems were more essential, practical and needed to students at university rather than that of an existing instruction. Thus, further studies are required to develop the education of environmental issues at universities like STSE programme.

The coexistence policy of GM and non-GM crops is still on the debates in EU since “the recommendation on guidelines for the development of national strategies and best practices to ensure the coexistence of GM crops with conventional and organic farming” has been reported in 2003. The major issues are maximum tolerance level of GMO admixture and minimum isolation distances of GM fields with others including conventional, organic and seeds production. Majority of member states in EU proposed that the tolerance level of GMO admixture must be more strictly controlled, in particular in the fields for organic crops and seeds production. To this end, it was proposed that minimum isolation distances to segregate GM crops from fields with organic crops and seeds production need to be further extended than those of conventional crops since cross pollination with other crops adjacent GM fields is known as the most prevalent source for GMO contamination. In these circumstances, it is strongly suggested that the current legislations need to be revised including the minimum isolation distances of fields for each species before field cultivation for a commercial GM crop is approved for the first time in South Korea.

The objective of this study was monitoring of genetically modified soybean by PCR and ELISA. We collected 60 soybean samples from the open markets located in Western Gyeongnam (Sacheon, Hamyang, Hadong, Sanchung, Uiryung, Geochang, and Hapcheon). A total of 60 soybeans was examined and 14 genetical modified soybean (GMS) were detected by PCR. The GMS rate of selling soybean in Uiryung, Hadong, Sacheon, and Hapcheon was 50.0%, 37.5%, 33.3% and 25%, respectively. The 7 of 14 GMSs were positive by ELISA and most of positive samples were below 3% GMS but 1 (Uiryung 1) of the positive samples was over the 3% which is maximum permit limit in Korea. These results mean that merchants of open market did not express for selling soybean mixed with GMS, so consumers did not recognize GMO. Therefore, we thought that education of GMO for merchant of open market need to recognize about GMO maximum permit limit.

현재 우리나라는 이상기후 현상이 발생하여 계획홍수위를 초과하는 극한홍수에 의한 피해가 심각해지고 있는 실정이다. 또한 도심지역에서 제방이 붕괴된다면 범람홍수파에 의해 적지 않은 인명 및 재산피해가 발생할 수 있다. 이와 같은 피해를 줄이려면 제방붕괴시 범람홍수파의 수리학적 거동특성을 명확히 규명하고 이에 따른 대피체계가 수립되어야한다. 이에 본 연구는 기존의 3차원 수치모형인 FLOW-3D를 통한 범람홍수파 특성연구에 조도계수 및 GMO(General Moving Object)를 추가하여 점진적인 제방붕괴로 인한 제내지에서 범람홍수파의 수리학적 거통 특성을 모의하였다. 높이 0.6m의 제방붕괴 단면이 시간에 따라 일정하게 넓어지면서 제내지로 홍수파가 유입되어 들어오도록 모의하였다. 수치모의 된 결과를 선행연구의 수리실험결과와 비교 검증을 수행하였다. 또한 수치모형 값에 조도계수를 입력하여 기존연구와 비교분석하였다. GMO를 이용하여 붕괴속도($v_0$)에 변화를 준 경우, 유속($v_{max}$) 및 수위($h_{max}$)변화에 큰 차이를 보이지 않았고, 초기 월류수심($h_0$) 변화에 따른 범람홍수파의 영향을 분석한 결과 붕괴속도 보다 큰 영향을 미치는 것으로 분석되었다. 본 연구결과의 활용방안으로 제방붕괴시 홍수범람에 의한 비상대처계획(EAP) 수립에 기초자료로 활용될 수 있을 것으로 판단된다.

Although new plant breeding technologies facilitate efficient plant breeding without introducing a transgene, they are creating indistinct boundaries in the regulation of genetically modified organisms (GMOs). The rapid advancement in plant breeding by genome-editing requires the establishment of a new global policy for the new biotechnology, while filling the gap between process-based and product-based GMO in terms of regulations. In this study recent developments in producing major crops using new plant breeding technologies were reviewed, and a regulatory model that takes into account the various methodologies to achieve genetic modifications as well as the resulting types of mutation were proposed. Moreover, the communication process were discussed in order to understand consumers' current situation and problems of new plant breeding technology, establish social acceptance well, and understand consumers' disputes such as GMO crops.

Diacylglycerol(DAG) was produced by enzymatic esterification of glyceryl mono-oleate(GMO) and conjugated linoleic acid(CLA) in a stirred-batch type reactor. The reaction was catalyzed by lipozyme RMIM(an immobilized lipase from Rizomucor miehei). DAG was isolated by a short-path distillation process and decolorized. DAG oil was composed of 87.3% DAG, 11.4% triacylglycerol(TAG), and 1.5% monoacylglycerol(MAG)(all w/w). Major fatty acids in DAG oil were oleic acid(54%), CLA(31.1%), and linoleic acid(7%). DAG oil iodine,and acid values were 108.8, 2.57, and 1, respectively. The DAG oil solid fat index(SFI) and thermograms were obtained using differential scanning calorimetry.
