For this study, cell surviving curves were obtained for mouse lymphoma YAC-1 cell line using semiautomated MTT assay. 2, 4, 6, 8, 10Gy were irradiated at a dose rate of 210cGy/min using ?Co lrradiator ALDORADO 8. After irradiation, YAC-1 cell lines(3×10⁴cell/ml) were exposed to bleomycin or cisplatin for 1 hour. The viable cells were determined for each radiation dose and/or each concentration of drug at the 4th day. And they were compared to control values. The obtained results were as follows: 1. The surviving curve with gentle slope was obtained after irradiation of 2, 4, 6, 8, 10 Gy YAC-1 cell line. 2. The cytotoxocity of bleomycin or cisplatin was increased significantly at all concentration of 0.2㎍/ml, 2㎍/ml and 20㎍/ml on YAC-1 cell line (P<0.01). And the cytotoxicity of cisplatin was greater than that of bleomycin at all concentration on YAC-1 cell line (P<0.01). 3. There were no significant differences of surviving fractions among 4Gy, 6Gy and 8Gy after irradiation of each radiation dose with 2㎍/ml of bleomycin compared with irradiation only on YAC-1 cell line. 4. There was significant difference of surviving fraction between 2Gy and 10Gy after irradiation of each radiation dose with 2㎍/ml of cisplatin compared with irradiation only on TAC-1 cell line (P<0.05). 5. There were significant differences of surviving fractions between the groups of irradiation only and the groups of irradiation with 2㎍/ml of bleomycin or cisplatin at all doses of 2, 4, 6, 8 and 10Gy on YAC-1 cell line (P<0.05).

방울토마토의 생산단계에서의 잔류허용기준 설정과 수확후 저장기간중 경시변화 및 세척에 의한 잔류농약의 감소양상을 파악하였다. 해당약제를 안전사용기준의 기준량 및 배량을 각각 시설재배 포장에서 살포후 10일간 잔류양상을 조사하였고, 실온 및 냉장조건 하에서의 저장실험 및 세척에 따른 전류농약의 잔소량을 파악하여 생산단계부터, 출하, 저장, 소비단계까지의 잔류량을 예측할 수 있는 모델개발을 위한 자료로 이용하고자 연구를 수행하였다. Dichlofluanid와 iprodione은 포장조건에서 반감일수가 기준량 2.2, 3.3일 이었으며, 배량은 3.5, 5.4일로 나타났다. 저장조건하에서의 약제별 반감기는 포장조건보다 잔류량의 감소속도가 느린 것으로 나타나 반감일수가 증가하였고, 세척방법에 의한 잔류농약의 감소량을 조사한 결과 세제 사용시의 평균제거율은 dichlofluanid는 73.7%, iprodione은 64.3%로 나타났고, tap-water 사용시에는 dichlofluanid 73.5%, iprodione 63.5%로 나타났다. 이러한 결과는 작물의 생산단계에서 구한 합리적인 희귀식을 이용하여 잔류농약의 경시변화를 파악하고, 저장 및 세척과정을 거쳐 최종 소비단계에서의 잔류농약의 수준을 평가할 수 있었다. We studied the residual patterns of two fungicides, dichlofluanid and iprodione, in cherry tomato greenhouse after applying with the recommended and double dose. Also, the degradation patterns during storage periods of up to ten days were compared between at room temperature (20℃) and at cold temperature (4℃). Removal rates of fungicides by washing with tap-water and detergent solution (0.1%, 0.2%) were measured. Half-lives of dichlofluanid and iprodione in greenhouse cherrytomato were 2.2~3.5 and 3.3~5.4 days, respectively. During the storage period, the residues were dissipated more slow. Removal rates were 62.8~80.3% by tap-water, 60.4~83.1% by 0.1% detergent solution, and 65.3~77.6% by 0.2% detergent solution. So, we can predict of terminal residues from cultivation period to marketing, storage and consuming.

천마의 항 불안 효과

김여환,최형철,손의동,이광윤,김원준,박형배,하정희 대한생물치료정신의학회 1996 생물치료정신의학 Vol.2 No.2

천마(Gastrodia elata Blume)의 근경을 말린 것은 한방에서 오래전부터 여러 형태의 간질발작 치료 목적으로 이용되어지고 있었으나 어떤 활성물질에 의해 또 어떤 작용 기전을 통해 약리작용을 나타내는지를 충분하게 설명하지 못하고 있다. 최근 항경련 작용기전 연구 결과 천마추출물의 GABA성 신경전달계에 대한 조절작용과 관련이 있을 것이라는 연구 결과가 보고되었으며, 소량으로도 뇌억제 및 진정작용이 있다는 문헌을 참고하여 볼 때 천마의 항불안 작용 가능성이 시사되었다. 이에 본 연구를 통하여 천마를 사용하여 실험동물에서 항불안 작용을 검색하고 그 작용기전의 일부를 밝히고자 항불안작용 기전에 중요한 benzodiazepine 수용체와의 상호작용을 관찰하였다. 실험 결과, 천마 추출물의 경구 장기투여는 생쥐의 elevated plus maze 검사에서 개방 통로에로의 진입 및 개방통로에서의 체류시간을 증가시킴으로써 항불안 효과를 나타내었다. 천마의 에탄올 추출물은 benzodiazepine수용체 길항제인 [³H] Ro15-1788결합을 억제하였으며, 천마 추출물은 [³H] Ro15-1788의 수용체 결합에 대한 최대 결합력(Bmax)은 변화시키지 않고, 친화력(affinity)을 감소시킴으로써 상경적인 결합 양상을 나타내었다. 또 천마의 에탄올 추출물은 benzodiazepine 수용체의 효현제인 flunitrazepam의 수용체 결합반응을 억제시켰는데, 이러한 억제는 GABA 존재하에서 항진되는 것을 관찰하였다. 이상의 결과로 미루어보아 천마의 에탄올추출물 내에는 항불안작용을 나타내는 성분이 함유되어 있을 가능성을 예상케한다. Gastrodia elata Blume is a medicinal plant which has been used as anticonvulsant in oriental medicine, and has been used as sedatives. A survey of the relevant literature has indicated that the putative anxiolytic activity of G.elata Bl. has not been scientifically investigated. Therefore, the present study was designed to assess anxiolytic property and interaction with benzodiazepine receptor of G. elata BI. The putative anxiolytic activity of ethanol extract of G. elata BI. was performed in mice using an elevated plus maze paradigm. Chronic oral administration of G. elata BI. showed anxiolytic action in mice. It was suggested that regulation of GABAergic neurotarnsmission may be important in the action of G. elata BI. The interaction of G. elata BI. with benzodiazepine receptor was investigated using rat cortices. Ethanol extract of G. elata inhibited the binding of [³H] Ro15-1788, a selective benzodiazepine receptor antagonist to benzodiazepine receptor. The inhibition of [³H] Ro15-1788 binding by G. elata BI. appeared to be competitive. Further, GABA significantly enhanced the potency of this extract in inhibiting [³H] flunitrazepam, a selective benzodiazepine receptor agonist, binding to benzodiazepine receptor. From these findings, it can be concluded that substance or substances with neurochemical properties characteristic of a benzodiazepine receptor agonist may contribute to the anxiolytic property of G. elata BI.

여광응,박현옥,최환석 한국특수교육문제연구소 2003 특수교육저널 : 이론과 실천 Vol.4 No.4

독해는 특정 교과에 한정되는 교과 활동이기보다는 모든 교과학습의 기초이기 때문에 초등학교 아동의 독해학습부진은 반드시 해결해야 할 중요한 과제이다. 기존에는 독해력 결함의 원인을 주로 상징과 소리 협응에 대한 법칙학습 장애나 시지각 장애로 귀착시켰으나, 최근에는 정보처리 과정상의 결함 내지 읽기에 관한 배경지식의 결함과 글을 읽고 이해하는 데 필요한 상위인지 전략의 선택 및 활용 부족을 원인으로 보는 경향이 유력하다. 이 연구는 상위인지 전략훈련(자기교시 전략훈련과 자기조절 전략훈련)이 초등학교 고학년 독해부진아의 독해력 향상과 유지, 자기효능감에 미치는 효과를 밝히기 위한 것이다. 연구 결과, 상위인지 전략훈련은 독해부진아의 독해력 향상과 유지에 긍정적인 영향을 미쳤으나, 자기효능감의 경우 양 집단 모두 뚜렷한 효과를 보였으나 양집단 간에는 효과의 차이가 나타나지 않았다. Recently, the strategy training for learning disabled children is widely applied so that learners themselves can set up self-planning, self-monitoring and self- evaluation, self-instruction and self-regulation strategy training methods that are based on the explicit instruction have proved their effectiveness. The purpose of this study is to compare the effect of self-regulation and self-instruction training methods for reading-comprehension on poor reader, and to investigate the improvement of the perception of self-efficacy for reading- comprehension of the children. In order to accomplish this purpose were 4th, 5th, and 6th graders of registered two primary schools within Daegu and selected 48 students who are delayed more than 1.5 year in their reading comprehension ability by the Reading Ⅱ(Reading Comprehension Test) of the fundamental learning ability test(by Park, Kyong-sook and others, 1985) and they were divided into two groups by 24 children at random. The children were randomly assigned to three conditions of self-regulation strategy training, self-instruction strategy training. The experimental group subjects were trained by two teachers at each experimenting school for 30 minutes, 5 times a week for 20 times in all by utilizing the self-study hours in the morning and lunch time. The following conclusion were obtained from the results and discussions of this study: First, the self-regulation and self-instruction strategy training is effective. The expected improvement of reading-comprehension ability of the self-regulation strategy training is higher than that of the self-instruction strategy training. Second, the effect of the self-instruction strategy training and the self-regulation strategy training is transferred to the effect maintains. The expected improvement of reading-comprehension ability of the self-regulation strategy training is maintained for a long time. Third, a relationship is revealed between the methods of the self-regulation and self-instruction strategy training is transferred to the improvements of self-efficacy for reading comprehension.

배수환,최광윤,정재동 대한건축학회 2003 대한건축학회 학술발표대회 논문집 - 계획계/구조계 Vol.23 No.1(구조계)

The purpose of this study is for the active use of the fly ash, which is a by-product of the combustion pulverizes coal thermal power plants, it should be used to compensate for the lack of landfill and for conservation of energy as the supplementary cementitious material, and to prove its possibility as the related products of the cement. First of all, the ordinary fly ash is ground in a special method and its fineness is controlled from 4000cm²/g to 6000 cm²/g, then replaced it with the 20% to 80% of the cement mortar to test of the physical properties. The first experiment is about the slow development of the strength of the fly ash mortar in early ages, and improves its strength with the activator Na2SO4, using a large amount of fly ash. On the other hand, in case of adding activator with steam curing, it rather shows the decrease of strength. This is that it needs to consider the influence by high temperature.
