채소종자의 발아와 초기생장에 대한 저선량 방사선과 종자수분함량의 영향을 알아보고자 배추, 무우, 고추, 호박, 참박 각각의 건조종자와 습윤종자에 저선량 감마선을 0~20Gy 수준으로 조사하였다. 수분함량을 상이하게 하여 관찰한 발아와 초기생장에 미치는 저선량 방사선 효과는 작물종에 따라 다르게 나타났다. 발아율의 경우는 건조종자보다 습윤종자에서 대체로 높았으며 저선량 효과는 배추와 호박의 습윤종자 4Gy와 2Gy에서 각각 33%와 13% 증가하여 뚜렷한 효과를 보였고, 참박은 건조종자 4~8Gy에서 높았다. 초기생장은 습윤종자에서 뚜렷한 효과를 보여 배추와 무는 10Gy, 호박은 2Gy, 참박은 8Gy에서 6~26% 정도 증가하였다. 이러한 초기생장 촉진효과는 저선량방사선과 수분함량 상호간에 유의적인 차이를 보였으며 특히 배추와 참박에서 가장 높았다. 즉, 채소 종자의 수분함량을 상이하게 하여 저선량 방사선의 효과를 조사한 결과 적정 수분함량에서 발아와 유묘생장이 촉진됨을 확인할 수 있었다. To investigate the effects of low dose gamma radiation and seed moisture content (SMC) on germination and early growth of vegetable crops, seeds of Chinese cabbage (Brassica camperstris L.), radish (Raphanus sativus L.), red pepper (Capcicum annuum L.), figleaf gourd (Cucurbita ficifolia Bouche) and bottle gourd (Lagenaria siceraria Stand), with different SMC were irradiated with different doses (0-20 ㏉) of gamma-ray by irradiator ^(60)Co, ca.150 TBq of capacity, AECL). Vegetable crops in which low dose gamma radiation was irradiated in seeds with different moisture content showed different response in seed germination and early growth to low dose gamma radiation. The germination rate of Chinese cabbage, figleaf ground and bottle gourd irradiated with 2-8 ㏉ showed interactive responses against relative SMC. Also, significant interactions occurred for the early growth between those factors. The stimulating effects of gamma radiation were more pronounced for hydrated seeds of Chinese cabbage, radish, figleaf gourd and bottle gourd showing prominent responses with 2-10 Gy irradiation, particularly for Chinese cabbage and bottle gourd. These results suggest that radiation may promote germination and early growth of vegetable crops through interaction with SMC.

In this study, a vehicle vector using cryptic plasmids was constructed for gene transfer in Helicobacter pylori. pHP51(3.9 kb) and pHP489(1.2 kb) were selected for constructing vectors from cryptic plasmid of H. pylori isolates in Korea. The HindⅢ-digestedDNA fragment(1.2kb) of pHP489 and 1.6kb DNA fragment of pHP51 were ligated with a kanamycin resistance gene(aph3'-Ⅲ) from C. jejuni to produce the recombinant plasmids pHP489K and pHP51K, respectively. Transformation frequency of pHP51K by electroporation was low. But pHP489K could be effectively transformed into various H. pylori strains. In order to design an intermdiate vehicle vector for gene transfer into H. pylori, pBlueHP489K was prepared by recloning pHP489K DNA into pBluescript and pTZ19R vector. This vector permitted the DNA fragment containing pHP489 sequence, aph3'-Ⅲ, and cloned DNA to be cut and self-ligated in the SacⅠ site after cloning. ureA and ureB gene were inserted into pBlueHP489K, resulting in pBlueHP489K/AB. The DNA fragment containing pHP489, kanamycin resistance gene(aph3'-Ⅲ), and urease structural gene was cut away from pBlueHP489K/AB and self-ligated to generate pBlueHP489K/AB. pBlueHP489K/AB made urease-negative H. pylori strains restore their urease activity. By this experiment, pBlueHP489K was confirmed to be the vehicle system for transferring H. pylori genes.

An optimization problem of AND-EXOR PLA's with imput decoders can be regarded as a minimization problem of Exclusive-Or Sum-Of-Products expressions (ESOP's) for multiple-valued input two-valued output functions. In this paper, we propose a minimization algorithm for ESOP's. The algorithm is based on an iterative improvement. Five rules are used to replace a pair of products with another one. We minimize many ESOP's for arithmetic circuits. In most cases, ESOP's required fewer products than SOP's to realize same functions.

우리 영동대학교에서 1998년 이후 지금까지 진행하여 온 특별 주제 학습과정인 STC(Special Topics COurse)프로그램을 기존의 운영틀에서 탈피하여 한층 더 발전시킨 복합STC로 활용하고자 하였으며, 특히 이를 졸업생의 취업 및 진학의 방법으로 최대한 활용하고자 계획·운영하였다. 그 결과 취업 및 진학과 같은 진로 확립은 물론 전공지식의 확대, 자격시험 대비능력의 향상, 학생과 교수간의 유대강화 등과 같은 괄목할 만한 성과를 얻을 수 있었으며, 교수들의 산업체 방문을 통한 산학협동의 계기 마련에도 커다란 성과를 얻었다. We have upgraded the STC(Special Topics Course) program, which has been carried out in our university since 1995, to more structured program so that we could train our chemical engineering students better. This program was geared to help students find better jobs and enter well-recognized graduate schools. Consequently, we had most students successful in job searches as well as entrance exams for graduate school; besides, those who actively participated in our STC program were able to attain better professional knowledge and acquire various professional engineers certificates. On top of that, this program allowed us to build up closer relationships with our students. We also made university-industry cooperation possible through our visits to industries nearby.

The purpose of this study is to investigate the actual conditions of preschool English education, and teachers' and parents' recognition of preschool early English education in Cheonan-city. Recently the importance of English education as an essential means for communication in the whole world is emphasized in our society. That atmosphere makes the elementary schools offer English as a subject in their curriculums, and also many preschool education institutes begin to teach English in their education courses. However before we begin to teach English as a subject in the preschool education, we need to survey the actual conditions of preschools and recognition of teachers and parents. The first part of this study is to survey the theoretical foundations of early English education; 1) the definition of early English education, 2) the situation of early foreign language education in foreign countries, 3) the relationship between the language acquisition and the cognitive development. The second part is to analyze the results of the questionnaire which was distributed among 86 teachers and 103 parents in Cheonan-city preschools. As a conclusion, some suggestions will be given for the development of early English education in the near future.

배양 마우스 신경세포에서 phenylpropanoid 유도체의 NMDA 및 산소/포도당 결핍 유발 손상에 대한 방어효과

위명복 제주대학교 생명과학연구소 1998 제주생명과학연구 Vol.1 No.-

The phenylpropanoids, naturally occurring compounds, have been known to contain the aromatic ring to which a three-carbon side chain is attached and various pharmacological actions. In our previous studies, we demonstrated that eugenol, one of the phenylpropanoid compounds has the neuroprotective effects in the in vitro and in vivo ischemia models. In this study, we studied whether other phenylpropanoid derivatives, myristicin, 4-allylanisole, α-asarone, and β-asarone have the similar neuroprotective action on N-methyl-D-aspartate (NMDA) or oxygen/glucose deprivation (OGD)-induced neurotoxicity in cultured mixed cortical Neurons. Between the 30μM and 300μM concentration, myristicim, 4-allyanisole, α-asarone reced LDH release by 9-95%, 0-88%, 14-77% and 15-98% against the NMDA(300 μM)-induced acute neurotoxicity, respectively. However, in the OGD paradyme, only both 4-allylanisole and α-asarone, significantly(p<0.05) showed 27% and 30% neuroprotective effect at the maximal concentration (300μM),respectively. These results suggest that phenylpropanoid derivatives may offer a helpful contribution for the improvement of the glutamate-related neurodegenerative diseases.

AbstractThe purpose of this study is to investigate theoretical foundation of syllabus design and create a new syllabus model which is based on previous studies on syllabus types and more appropriate for new needs for English education in the 21th century and for the 7th national curriculum in Korea. Chapter 2 defines the essential roles of syllabus design in the whole English education context. Chapter 3 deals with the theories and characteristics of the Synthetic Syllabus types, which include Grammar-Structural Syllabus, Notional-Functional Syllabus, Situation-Topic Syllabus, and Lexical Syllabus. Chapter 4 deals with the Analytic Syllabus, so chapter 4 compares the characteristics of Analytic Syllabus, so chapter 4 compares the characteristics new theories about Procedural Syllabus, Process Syllabus, and Task-Based Syllabus. Chapter 5 introduces a new syllabus model -Multi-Syllabus Model. This model combines the characteristics of both Analytic Syllabus and Synthetic Syllabus. This Syllabus Model can play an essential role in syllabus model development because this new model is very useful for developing the 7th national curriculum in Korea and also for meeting new needs for English education in the 21th century.
