GM작물의 상용화를 위하여서는 반드시 환경위해성평가를 거쳐야 한다. 불행하게도 초기 event가 개발되고 기본적인 검토가 완료된 GM작물에 대하여 환경위해성평가를 수행하기 위하여서는 약 7백만에서 1,500만불의 경비가 소요되며 기간 또한 수년이 필요하다. 따라서 저자는 사용화를 위한 GM작물의 개발을 위한 프로젝트에 관여하는 개발자는 실험실 또는 온실단계의 아주 초기단계에서부터 환경위해성평가기준을 충분히 숙지하여야 한다고 제안한다. 기존의 많은 리뷰논몬에서 이미 지적된 것 과 같이 GM작물의 상용화과제에서 가장 큰 걸림돌(죽음의 계곡)은 초기 사상 (event)의 선발과정이며, 대부분이 이 단계에서 충분한 자료를 제시할 수 없어서 포기한다는 사실을 간과하여서는 안 될 것이다. 특히 지극히 기본적인 분자생물학 특성에 관한 자료들로서 예를 들어 도입유전자의 copy 수, 숙주의 게놈내 도입위치, 도입유전자의 주변 염기서열, 유전자 재배열과 도입유전자로 인한 숙주 내 기존유전자의 knock out 현상의 여부 등에 관한 충분한 자료를 제시하지 못하는 경우가 많으며 이는 GM 작물의 개발 초기단계에서부터 철저하게 검증이 이루어져야 하는 항목들이다. 국내의 경우, 농촌진흥청은 2011년부터 2020년까지 10년간 "차세대바이오그린 21 사업"을 발족하여 추진 중에 있으며 특히 국내용뿐만 아니라 중국의 사막화 지역 등 불량환경에 재배가 가능한 GM작물 등 해외로 수출을 위한 global GM작물의 개발을 위한 전략을 수립하여 추진 중에 있다. 따라서 저자는 환경위해성평가기준에 부합되는 초기 event의 선발 과정에 역점을 두어 사전에 분자생물학적 특성에 관한 RA기준을 고려하여 자체평가시스템을 도입하도록 제안 한다.

Excessive microglial activation and subsequent neuroinflammation lead to synaptic loss and dysfunction as well as neuronal cell death, which are involved in the pathogenesis and progression of several neurodegenerative diseases. Thus, the regulation of microglial activation has been evaluated as effective therapeutic strategies. Although dieckol (DEK), one of the phlorotannins isolated from marine brown alga Ecklonia cava, has been previously reported to inhibit microglial activation, the molecular mechanism is still unclear. Therefore, we investigated here molecular mechanism of DEK via extracellular signal-regulated kinase (ERK), Akt and nicotinamide adenine dinuclelotide phosphate (NADPH) oxidase-mediated pathways. In addition, the neuroprotective mechanism of DEK was investigated in microglia-mediated neurotoxicity models such as neuron-microglia co-culture and microglial conditioned media system. Our results demonstrated that treatment of anti-oxidant DEK potently suppressed phosphorylation of ERK in lipopolysaccharide (LPS, $1{\mu}g/ml$)-stimulated BV-2 microglia. In addition, DEK markedly attenuated Akt phosphorylation and increased expression of $gp91^{phox}$, which is the catalytic component of NADPH oxidase complex responsible for microglial reactive oxygen species (ROS) generation. Finally, DEK significantly attenuated neuronal cell death that is induced by treatment of microglial conditioned media containing neurotoxic secretary molecules. These neuroprotective effects of DEK were also confirmed in a neuron-microglia co-culture system using enhanced green fluorescent protein (EGFP)-transfected B35 neuroblastoma cell line. Taken together, these results suggest that DEK suppresses excessive microglial activation and microglia-mediated neuronal cell death via downregulation of ERK, Akt and NADPH oxidase-mediated pathways.

Composting is among the most effective integrated waste management strategies used to recycle sewage sludge (SS) waste and generate a useful product. An encapsulated lifting system is a relatively new industrial-scale composting technology. The objective of this study was to evaluate the effectiveness of composting dewatered stabilized SS mixed with green waste using this new technology. The composting process was monitored by changes in the physico-chemical properties, UV-visible spectra, and fourier transform infrared (FTIR) spectra. The composting temperature was steady in the thermophilic range for 24 and 12 d in the intensive and maturation phases, respectively, which fulfilled the disinfection requirement. Moreover, the temperature increased rapidly to 76.8℃ within three days, and the thermophilic temperatures peaked twice and lasted longer than in traditional composting, which accelerated SS degradation and decreased the composting period necessary to obtain mature compost. FTIR spectroscopic analysis showed a diminished in methyl group derived from methylene C-H aliphatic groups because of organic matter degradation by microorganisms and an increased number of aromatic chains. The new technology may be a viable and sustainable alternative for SS management that converts waste into compost that is useful as a soil amendment.

The purposes of the study were to; 1) examine the diffusion and adoption of new agricultural technology in rice farming, 2) survey the status of agricultural education institutions on technology transfer, and 3) explore the linkages between agricultural education and extension for more effective reinforcement strategies to further the diffusion and adoption of new agricultural technology in Korea. Literature review, field survey and panel discussions were employed to strengthen the linkages among agricultural education, research and extension in Korea. As the results of analysis of the diffusion and adoption of new agricultural technology in rice farming following recommendations were offered; 1. Extension services have helped Korean farmers in achieving self-sufficiency in rice and year-round supply of green vegetables as well as upbringing rural youth, however, government changed the status of extension educators from central government staff to county/city government staff since 1997. This brought about various problems such as: decreased morale and number of extension educators, thus weakening the extension education function, weakened linkages between national and local extension offices, less opportunity for in-service education of extension educators, and weakened linkages between agricultural research and extension, etc. 2. In order to insure that extension educators are high caliber professional individuals, it is crucial to establish a system that nationally recognizes these individuals as such, and that provides a professional development path. It is important to restore the morale of extension educators to continually achieve the national goals of food production, balanced national development and preservation of environment, at the same time to meet increasing needs of farmers. 3. Because of the critical importance of diffusing innovations to agricultural producers in order to ensure quality and steady food supply, it is crucial that these issues be addressed before the extension service further deteriorates. Further research activities on agricultural extension should be conducted for more effective agricultural extension system in Korea to achieve a greater rural, national and regional development. 4. Research and implementation activities should be emphasized and encouraged to improve the cooperation and collaboration among agricultural education research and extension to better serve farmers' educational and information needs. National level research activities should be encouraged to improve the effectiveness of agricultural technology transfer including internet education programs for farmers in Korea.

Gradient concentrations of Tithonia diversifolia green leaves and phosphate rocks were used to investigate their contributions as a fertilizer to the yield and quality improvement of a rainfed rice cultivar. Six treatments were compared: (1) T0, no fertilization (control); (2) T1, 1.28 g of phosphate rocks; (3) T2, 250 g of organic matter; (4) T3, 500 g of organic matter; (5) T4, 250 g of organic matter + 1.28 g of phosphate rocks; (6) T5, 500 g of organic matter + 1.28 g of phosphate rocks. The results showed that the germination percentage recorded 15 days after sowing varied from 58 - 76% between T0 and T5. The number of panicles ranged between 2 (T0) to 6.3 (T5). Moreover, the recorded length of the panicles ranged between 7.5 (T1) to 15.8 cm (T2), and the number of grains per panicle ranged between 25.5 (T1) to 273.5 (T3). The plant height was significantly increased in the T5 (79.27 cm) group compared to the T1 (33.63 cm) and control treatment (T0) (40.08 cm) groups. Although the plant height in the T2, T3, and T4 groups was slightly lower than the T5 group, the difference was not statistically significant. The average of the grain number per plant was high in the T3 (273.6 grains) group compared to the T1 and T0 (25.5 and 32.8 grains) groups, respectively. These results suggest that the combination of T. diversifolia leaves and phosphate rocks as a natural fertilizer would be beneficial when integrated into soil fertility management strategies and would contribute to improving crop yield and quality.

This study was aimed to explore the level of awareness of Korean teachers and college students towards sustainable development(SD) and education for sustainable development(ESD). A survey was conducted to understand the present status of awareness of SD and ESD among 317 college students and 625 teachers in Korea from April to May of 2005. The questionnaire included items asking whether they heard about terms such as sustainability or sustainable development, the source of information on SD, the level of understanding or the urgent task for SD in Korea. It also included questions about experiences in participating in or conducting ESD, the need for ESD, important areas in and the modality for ESD and the willingness to participate in ESD. The results showed that the level of awareness on SD among teachers was low compared to college students, who have a relatively high level of access on SD issues through textbooks and classes in high school. Interestingly, most of college students replied that they never received any ESD, even though they learned SD in class. Both the teacher and student group thought that tile priority of sustainable development should be an 'environment-related' area in the social, economical and environmental perspectives. Most of the students and teachers considered the concept of SD as 'pursuing the balance between environmental protection and economic development.' Some of the teachers recognized the concept of sustainable development in the paradigm of continuous economic development. Both groups responded that the urgent task related to sustainable development is 'environmental protection' and the 'reduction of poverty.' On the other hand, they had experiences in teaching related to natural resources, gender equity, health, human rights, climate changes and other SD issues in class, but not under the name of ESD. They also emphasized 'critical thinking and problem solving & decision-making' in education. Most of the students and teachers responded that it was needed to carry out ESD, and that the way of life for SD would be the priority. It is suggested that various pedagogy and modalities according to various target groups should be considered in providing ESD. It is necessary to use more effective strategies for ESD rather than just introducing the concept of SD. Also, it is needed to review the ESD practices of teachers and improve the quality of education within the scope of ESD.

The purpose of this study was to describe the way of life (such as smoking habits, alcohol consumption, exercise, duration of sleep, eating habits etc.), physical. psychological and overall health complaints and to identify the relationship between the way of life and health complaints of the nursing students. Data was collected with the self-administered OMI( Okayama Medical Index Health Questionnaire, devised Cornell Medical Index) from 766 nursing students and was analyzed. For data analysis, descriptive statistics and an ANOVA with an SPSS/PC+ program were used. The results were as follows: 1. The mean age of subjects was 21.0557(2.7618) years old in their 1st, 2nd, 3rd and 4th year-classes of nursing departments and college students in 4 regions of Korea. 62.1% of subjects were of the proper body weight, 2.0% were overweight, and 28.3% were underweight. Most subjects did not have a past history of disease, but 1.8% of subjects had experienced a blood transfusion. 2. 28.3% of the subjects had averaged 7 hours of sleep, 98.5% were nonsmokers, 91.2% were nondrinkers, 74.7% of subjects had milk intake sometimes, 53.7% of the subjects had an average salt intake, 49.6% of the subjects usually had a green vegetable intake, 45.4% of the subjects sometimes had fatty food intake, 64.8% of the subjects had good taste, 29.5% of the subjects enjoyed physical exercise. 3. The highest percentages of 'yes' among physical. psychological and overall health complaints were observed in the question 'Do you have gastric pain?'(60.2%), 'Are you confused of disorderly?' (37.2%), 'Physical body was burdensome and fatigued.'(57.3%). 4. The total O.M.I. score ranged from 1 to 89 with an average of 22.91(SD=12.10). A statistically significant difference was observed for the physical. psychological complaints for alcohol consumption. and for the psychological complaints for salt and fatty food intake. These conclusions should provide grounds for future studies of strategies for health promoting lifestyle for nursing students and their health concerns. Further research is required to investigate the life environmental and psychological factors affecting the way of life for nursing students and their health status, to analyze the health behavior of nursing students related with their culture and consciousness. Also epidemiologic research methodology, such as prospective cohort study should be considered to explore the performing process of nursing student's health behavior related with the occurrence of diseases.
