  • The environmental risks of cucumber mosaic virus resistant transgenic chili peppers with the CMVP0-CP gene on non-target organisms in the agroecosystem environments was evaluated during the periods of the chili pepper growing season (June 19, July 30, August 31) in 2007. Arthropods assemblages leaves and flowers of chili peppers were quantitatively collected by using an insect vacuum collector to compare the arthropod community structures between non-transgenic chili peppers (nTR, P 915) and mosaic virus resistant transgenic chili peppers (TR, CMV-cp, line 7). There was no statistical difference in the arthropod community structure between the two types of crops, nTR and TR, at the same season, although the species richness and Shannon's index were somewhat different among seasons; indicating no effects of genetically modified peppers on the arthropod community. However, further studies were required to conclude more concretely for the potential environmental risk of the transgenic chili pepper of CMV-cp.

  • Genetically modified (GM) pepper H15 containing the gene for cucumber mosaic virus (CMV) coat protein (CP) and its control line non-GM pepper P2377 were investigated for their allergic risk. Amino acid sequence of the inserted gene product CMV-CP was compared with those of known allergens. No known allergen had greater than 35% amino acid sequence homology over an 80 amino acid window or more than 8 consecutive identical amino acids. Protein patterns of GM and non-GM pepper extracts were evaluated by SDS-PAGE, which showed similar distribution of protein bands for both GM and non-GM pepper. Antigen-antibody reactions were compared between GM and its non-transgenic parental control. ELISA and immunoblot analysis of sera from allergic patients showed some IgE reactivity; however, no differences were observed between GM pepper H15 and P2377. We therefore conclude that CMV-CP is less likely to be an allergen; the protein composition and allergenicity of the GM pepper H15 is not different from that of P2377 and safe as a commercial host.

  • To assess the environmental risks of transgenic chili pepper with PepEST gene on non-target organisms before it exposes to the agro-ecosystem environments, we conducted the three sets of green peach aphids (Myzus persicas S.) life table experiment under laboratory conditions (Temp. $25^{\circ}C$, R.H. 50-70%, Photoperiod L16 : D8) in series during 2005-2006. We measured the net reproductive rate ($R_0)^*$, the intrinsic rate of increase ($r_m$), the mean generation time ($T_c$), $fecundity^*$, life span, and reproduction period between non-transgenic chili peppers and transgenic chili peppers, respectively. The life span of green peach aphids from three sets was 31, 27, 25 days, and the period of life span was similar to the general average length of green peach aphids, 25-29 days. Although the first reproduction of transgenic pepper was similar to the non transgenic pepper (P>0.05), the fecundity and the net reproductive rate ($R_o$) by using Jackknife method of transgenic pepper were lower than those of non transgenic pepper (P<0.05). Conclusively, we observed the adverse effect from our results but we should execute further experiments to confirm the results at the fields with the similar way.

  • This study performed compositional analyses of a genetically modified herbicide-tolerant red pepper (GMHT), developed by the Rural Development Administration, and a parental red pepper cultivar 'Subicho', and compared the nutrient composition of them. Using the Association of Official Analytical Chemists (AOAC) methods, the study measured the concentration of nutrients, including the proximate components (protein, fat, fiber, ash, and carbohydrates) and minerals (Ca, K, Na, Fe, Mg, Zn) of GMHT and 'Subicho'. Nutritional composition of GMHT and 'Subicho' were compared with the nutritional composition of conventional red peppers. The nutrient composition of GMHT and 'Subicho' were found similar, and GMHT's nutrient contents were in the range of those of the conventional red peppers. These results showed that GMHT's nutrient contents were equivalent to those of the parental red pepper and other conventional red peppers.

  • For the development of genetically modified plants, it is important to verify various factors which potentially affect the risk assessment as well as to establish an experimental program to produce scientific and reliable data. However, it is a time and cost consuming process to develop GM plants as well as to prepare scientific and convincible data for government's approval. Therefore, using the transgenic hot pepper tolerant to a new CMV pathotype, we attempted to suggest few methodological procedures, such as probe saturation for southern blot analysis and RT-PCR and ELISA for expression analysis, for identification and stability evaluation of inserted gene in genetically modified plant which are required for submission for approval. Ten partially overlapped probes covering full length of inserted gene were produced. We could identify that the inserted gene was stacked as a single copy as well as no partial element existed. Also, we could identify the stability of the inserted gene stacked in hot pepper using probe saturation. In the expression analysis with RT-PCR and ELISA, we also could provide the stable expression of transcript and proteins in leaves and placenta and pericarp of fruits of the CMV-resistant hot pepper.

  • This study was conducted to assess the environmental risks of anthracnose resistant transgenic chili peppers with the PepEST gene on non-target organisms in the agroecosystem environments during the chili pepper growing seasons in 2006. We quantitatively collected arthropods assemblages living on leaves and flowers of chili peppers on June 20, July 25, and August 25 by using an insect vacuum collector to compare the patterns of arthropod community structures between non-transgenic chili peppers (nTR, WT512) and anthracnose resistant transgenic chili peppers (TR, line 68). We found the seasonal difference with the highest species richness and Shannon's diversity in July's sampling among the growing seasons (P<0.05) and each sampling season showed the different arthropod community composition. We also found there was no statistical difference between the two types of crops, nTR and TR, at each sampling time (P>0.05). The significance level of arthropod community showed that there were lots of seasonal difference of functional groups as well as taxa but only the herbivore group in the functional groups was significantly different for the types of plants (P<0.05). So, we further examined the herbivore groups to find any potential damage and identified the possibility of herbivorous damage from some herbivores, grasshoppers, aphids and thrips. Although we couldn't find any adverse effects from the environmental risk assessment between the arthropod community structures on two types of plants from our results, we should keep working for the environmental risk assessment because of the herbivorous potential risk possibility.

  • 농업 유전공학 기술은 생산성 향상, 환경보전, 식품의 안정성 및 품질향상에 기여함은 물론 농업의 경쟁력을 높일 수 있는 유일한 대안으로 인식되고 있다. 전 세계적으로 유전자 재조합 작물의 경작지는 2000년 한해동안 지난해 같은 기간에 비해 11% 증가하였으며 이는 1996년 대비 25배 증가하였고, 선진국과 개발도상국은 각각 2%, 51% 1999년 대비 증가하였다. 1983년 유전자 재조합에 의한 식물의 형질전환이 성공한 뒤 종묘업계는 형질전환 종자개발과 보급에 열중하고 있으며 종자시장에 형질전화 품종이 차지하는 비율은 2000년 30억 달러에서 2010년이면 전체의 60%인 200억 달러에 이를 것으로 전망된다. 1995년 제초제 저항성 콩(라운드업레디콩)이 농가에 보급된 이후 2000년 형질전환품종 재배면적이 3990만 ha에 이르렀고 1997년 미국과 캐나다는 옥수수, 대두, 면화, 감자, 유채 등의 형질전환 품종 재배로 각각 3억1400만 달러, 5300만 달러를 벌어들였음. 형질전환 품종의 보급 증가속도는 소비자들의 GMO에 대한 거부반응으로 다소 주춤한 상태이다. 그러나 최근 종자회사들은 생태계 위해성 논란을 피해갈 수 있는 연구로 이러한 상황을 돌파하려 하고 있다. 우리나라에서도 유전자변형 생물체에 관한 법률이 제정되었으며 많은 대학과 연구소에서 형질전환 연구가 꾸준히 이루어지고 있고 최근 제초제 저항성 벼와 바이러스 저항성 감자가 개발돼 GMO 안정성 점검에 들어가 있고, 살충성 배추, 혈압강하 토마토, 지방산 강화 들깨, 병저항성 고추 등도 실험실과 포장에서 재배되고 있다. 이르면 4-5년 뒤 형질전환 작물들이 농가에 보급될 전망이다. 이처럼 체크 툴은 Firewall의 수비능력을 보강하는 위치에 있다고 생각할 수 있다.다. 4 장에서는 3장에서 제기한 각각의 문제점에 대해 RAD 의 관점에 비추어 e-business 시스템의 단기개발을 실현하기 위한 고려사항이나 조건 해결책을 제안한다. 본 논문이 지금부터 e-business 를 시작하려고 하는 분, e-business 시스템의 개발을 시작하려고 하는 분께 단기간의 e-business 실현을 위한 하나의 지침이 된다면 다행이겠다.formable template is used to optimize the matching.

As a result, conventional NN and CNN were available for interpolation of sampling data. Moreover, when nonlinear intensity is not so large under the field condition of small slope, interpolation performance of CNN was a little not so better than NN. However, when nonlinear intensity is large under the field condition of
