황을철,김정기 동아대학교 환경문제연구소 1993 硏究報告 Vol.16 No.2

Apples, peaches, and persimmons collected from their chief producing districts and trading centers in 1992 respectively were analyzed for chlorothalonil, fenitrothion, and phenthoate residues by glc equipped with a electrn capture detector or a nitrogen phosphorus detector. The results obtained are as follows : Average and range of chlorothalonil residue levels n apples was 0.008ppm and ND-0.030ppm, and in peaches 0.010ppm and 0.073ppm, respectively, while no chlorothalonil was detected in persimmons. No organophosphorus pesticides such as fenitothion, chlorpyrifos, and phenthoate were detected in all fruits. In all fruits, even the maximum residue level, not to mention the average, of four pesticides examined was much lower than its maximum residue limit(MRL) respectively.

벼와 피에서 제초제 alachlor의 선택적 작용

황을철,우승희 東亞大學校生命資源科學大學附設 農業資源硏究所 1995 農業生命資援硏究 Vol.4 No.1

벼와 피에서 α-chloroacetamide계 제초제의 선택적 작용, 특히 포장에 이앙하는 어린모의 벼(약 40일묘)와 발아중인 피에서 alachlor의 선택적 작용이 발현되는 근거를 찾고자, 벼와 피에서 몇가지 생화학적 차이를 조사하였다. 제초제 alachlor에 의한 약해는 생장일수가 동일한 유묘기의 벼와 피에서는 비슷하였으나, 생장일수가 서로 다른 40일묘의 벼와 7일묘의 피에서는 현격한 차이가 있었다. Alachlor에 대하여 약해정도가 현격히 다른 40일묘의 벼와 7일묘의 피체내의 GSH 함량과 GST 활성은 서로 비슷하였으며, alachlor 처리에 의한 GSH 함량과 GST 활성의 증가도 모두 미미하였다. 40일묘의 벼와 7일묘의 피에서 alachlor 처리에 의해 저해되는 α-amylase의 활성은 무처리에 비해 각각 93.5%와 70%로 현격한 차이를 나타내었으며, 이는 약해정도와 부합하였다. 따라서, 40일묘의 벼와 7일묘의 피에서 발현되는 alachlor의 선택성 또는 벼를 이앙한 포장에서 발아중인 피를 방제하는 α-chloroacetamide계 제초제의 선택성은, 벼와 피체내의 방어계인 glutathione conjugation 반응에 기인하는 것이라기 보다는, 종실내의 주된 저장영양분인 탄수화물의 이용에 관련된 효소인 α-amylase가 저해되는 정도에 기인하는 것으로 판단되었다. Several biochemical differences between rice and barnyardgrass which were related to glutathione conjugation and utilization of starch reserves in seeds were examined to investigate the selectivity of α-chloroacetamide herbicides in rice and barnyardgrass, especially in transplanting staged rice (about 40-day-old) and germinating barnyardgrass. Phytotoxicities of alachlor to rice seedlings and barnyardgrass seedlings were all severe at stronger concentration that 1.0×10-6 and were similiar to each other at various concentrations. However, 40-day-old rice which was independent on the seed reserves was tolerant to alachlor. Glutathione(GSH) content and activity of glutathione S-transferases(GST) in roots of rice seedlings and barnyardgrass seedlings were similiar to each other, and those of 40-day-old rice and barnyardgrass seedlings which were observed to show different responses to alachlor were so. Moreover, the inductions of GSH and GST in 40-day-old rice and 7-day-old barnyardgrass following treatments with 1.0×10-5 solution of alachlor were insignificant. On the other hand, activities of α-amylase in seeds of 40-day-old rice and 7-day-old barnyardgrass following treatments with 1.0×10-5 solution of alachlor decreased to 93.5% and 70.0% of the control respectively. These results were consistent in phytotoxicities above stated. It was therefore stated that the selectivity of alachlor, α-chloroacetamide herbicide in 40-day-old rice and germinating barnyardgrass was due to inhibition degree of α-amylase needed for starch utilization as energy sources in grass germlings, rather than due to the rate of glutathione conjugation generally considered as main factor contibuting to α-chloroacetamide herbicide detoxification and selectivity.

This study aims to diagnose factors that influence on proper ego-identity development of adolescents through a training activity, voluntary service for future adolescent policy through analysis of a causal model. As a result of the analysis, it was reported that training, leisure and cultural activites have an statistically significant influence on ego-identity formation of adolescents except the motive to achieve, a member of dependant variables. First, training activities have a significant influence on self-esteem, motive to achieve, sociality and morality, especially on development of sociality, So it was suggested that for the adolescents who need to be socially developed, active participation in training activities should be recommended to promote self-identity formation. Second, it was reported that leisure and cultural activites have a statistically significant influence on self-esteem, motive to achieve, sociality and morality, and especially on morality development. Therefore, it was suggested that leisure and cultural activites should be actively developed to help their self-esteem development. According to the results of analyses, it was confirmed that the training activity, leisure and cultural activity is an important factor that influences on ego-identity formation. It is suggested that a development program should be politically promoted. Therefore, this study presents suggestions for a future adolescent educational program in view of training activities, leisure and cultural activites.

손병길,최은석,정을수,신종현,김명진,지용철 대한척추신경외과학회 2004 Neurospine Vol.1 No.1

Objective: The lumbar spinal canal can be devided into the central zone and the lateral zone. The divisions of the lateral zone are the subarticular, the foraminal, and the extraforaminal zone. A common causes of the operation for the spinal stenosis are related to the association with the spondylolisthesis and the central stenosis. There is a paucity of data, however, regarding the operative intervention in the lateral zone stenosis(LZS). Our aim was to analyze the surgical result by the anatomical type and the operative method. Methods: 72 patients of LZS excepting the association with the spondyolisthesis have been operated by six neurosurgeons of our hospital from 30th April, 1994 through 30th September, 2002. The patients had been interviewed about surgical result through telephone by third party persons. The surgical results were analyzed by the four score rating system: ① medication, ② ADL(Ability of daily living), ③ the degree of improvement, ④ the degree of satisfaction. Results: Among 72 patients, there were 25 males and 47 females. The age group of the patients were in their thirties(1), forties(9), fifties(21), sixties(36) and seventies(5). Surgical methods were used on decompression(22), posterior lumbar interbody fusion(PLIF) with cage(1) and PLIF with transpedicular screw fixation system(49). The types of stenosis were subarticular(24), foraminal(16) and extraforaminal(30) and double crush(2). The overall surgical results were Excellent(18), Good(34), Fair(19), and Poor(1). The Non-success rate according to the methods of surgery were decompression(34.8%), PLIF with transpedicular fixation system(24.4%). The overall success rate was(53/72: 73.6%). The success rate according to the types were subarticular(17/24: 70.8%), extraforaminal(21/30: 70%), and foraminal(12/16: 75%). Conclusion: It is suggested that the result was more favorable on the cases of lateral zone stenosis operated with PLIF and transpedicular fixation system. According to the method used, the success rate of decompression was worse than PLIF with transpedicular fixation system.
