과학의 발달과 우주관의 변천

장만채 순천대학교 기초과학연구소 1996 基礎科學硏究誌 Vol.7 No.-

현대는 과학의 시대이다. 우리는 아주 사소한 것에 까지 과학의 도움을 받아 가며 살아가고 있다. 불과 몇 년 전 까지만 해도 상상속에서만 가능했던 일들이 지금은 실현 가능하게 되었고 또 앞으로 몇 년 후에는 지금 상상하고 있는 일들을 직접 몸으로 체험할 수 있을 것이다. 급격한 경제 발전과 아울러 인간들의 지식수준의 향상에 따라 과학은 점차 발달하고 있다. 보다 나은 그리고 보다 편리한 삶을 추구하기 위해 인간들은 지금도 부지런히 뛰고 있다. 너무 앞만 보고 달려가기 때문에 인간의 창조물인 과학의 노예가 되어버린 것인 아닌가 하는 생각마저 들곤 한다. 부의 축적에 따른 거대한 가옥구조와 높은 담장은 이웃과의 단절을 의미한다. 또 과학의 발달에 따른 사람들의 사고방식에도 큰 차이가 있다. 남편과 부모 그리고 자식들을 위해 새벽부터 군불을 지펴가며 밥 짓고, 밤새도록 마주앉아 다듬이질 하던 그 정성, 추운 겨울에도 손 '호호' 불어가며 빨래하던 아낙네들의 그 여린 마음들을 지금은 간단한 전자 밥통과 세탁소, 세탁기가 대신 해주고 있다. 한 벌의 옷을 만들기 위해 며칠동안 밤낮없이 베를 틀던 조상들의 그런 따사로운 손길대신 백화점에 진열된 똑같은 수많은 옷들이 주인을 기다리고 있다. 이 점에서 알 수 있듯이 과학의 발달에 따라 인간 생활 수준의 향상과 문화적 수요가 증가되었지만 따뜻한 마음씨와 정을 나누던 구수한 풍경은 사라져 가는 것이 현실이다.

To investigate the effect of heavy metals on enzyme activities of liver during chick embryogenesis, methods of histologic and histochemical procedures were used. Cylinderical hepatic tissues arised in diverticulum at 3 days embryo. Histological and morphological framework of liver was accomplished at 6 days embryo. Liver cell cords, sinusoid and central veins of hepatic tissue were shown while liver lobules were not obvious during embryogenesis. In heavy metal treated groups, vesicles of fat were increased in numbers and size during embryogenesis. High as well as moderate alkaline phosphatase activities in sinusoid lining cells were continuously shown in the control group during embryogenesis. Moderate to weak alkaline phosphatase activities exist at the same sites in the mercury and lead treated groups. Five prime-nucleotidase and glucose-6-phosphatase activities in the heavy metal treated groups were similar to the those of the control group. Activities of adenosine triphosphatase were prominent at bile canaliculi; however those at the endothelial cells of central veins, and hepatocytes were low in the control group. Adenosine triphosphatase activities were decreased in the heavy metal treated groups. In the control group, moderate lactate dehydrogenase activities at sinusoid lining cells were shown in the period from the 4th day of embryo to one day old hatching chick. Lactate dehydrogenase activities at bile canaliculi increased gradually to remarkable levels in differentiation period. In the heavy metal treated groups, sinusoid lining cells showed weak activities until the 8th day of embryogenesis. At all sites, malate dehydrogenase activities of the control group showed weak to moderate levels during embryogenesis. In the heavy metal treated groups, malate dehydrogenase activities were low at early embryogenesis.

A study on the determination for degree of green naturality in Suncheon city was conducted as the part of the project for investigation of green capacity, Cheonnam from 1989 to 1991. Through the determination for degree of green capacity in Suncheon city, the totality of green nature in the surveyed area was transformed to degree of green naturality(DGN) which is one of the barometers indicating the extent of destruction of natural green vegetation. The whole area of Suncheon city was divided into one-kilometer squares, total 90 meshes. Each of these squares meshed was given a rating in the degree of green naturality in vegetation. These ratings are an measure of how much nature remain intact. They also show the extent to which nature has been destroyed by man. The findings on this point constitute a principal feature of the survey. The survey was carried out in a belief that quantitative measurement are needed to learn about the impact on the human living environment. Four different grades of green naturality ; DGN 1, 2, 6 and 7 have been registered in Suncheon city. Prominent DGN was 2, which occupied 36.7% of the survey area. Average of degree of green naturality was recognized as 4.12 in whole area. The volume of vegetation existing in Suncheon city was estimated 347,690 tons, and vegetation out-put was estimated 72,630 tons in one year. The numbers of protected tree investigated in Suncheon city were 4 provincial tree, 11 city-county tree and 41 village tree, total 56 protected tree.

An analysis on the degree of green naturality in Sungju country has been conducted as the part of the project for study of green capacity. Cheon-nam province from 1988 to 1990. Through the determination for degree of green capacity in Sungju county, the totality of green potential in the surveyed area was transformed to degree of green naturality(DGN) which is one of the barometers indicating the extent of destruction of natural green vegetation. The whole area of Sungju county was divided into one-kilometer squares, total 834 meshes. Each of these squares meshed was given a rating in the degree of green naturality in vegetation. These ratings are an measure of how much nature remain intact. They also show the extent to which nature has been destroyed by man. Eight different grades of green naturality ; DGN 0,1,2,3,4,6,7 and 8 has been registered in Sungju county. Prominant DGNs were 6 and 7, which occupied 75.2% of the survey area. Average of degree of green naturality was recognized as 5.5 in the whole area. The volume of vegetation existing in Sungju county was estimated 4,454,560 tons, and vegetation out-put was estimated 707,240 tons in one year.

It is shown that the free field representations of Z_N-symmetric conformal quantum algebras of Fateev, Zamolodchikov and Lykyanov can be obtiained based on the field realizations of the algcbras given by Bilal and Gervais from their study of classical SU(N) Toda field theory through the one parameter dependent linear transformation, where this parameter determines the central charge.

韓藥資源 流通에 關한 基礎硏究 : Ⅰ. 主要 栽培韓藥材의 流通過程에 있어서의 問題點과 改善方向 Ⅰ. The Problems and Improvement Direction in Major Culturing Chinese Herbal Medicine Stuffs

崔成圭,崔景柱 순천대학교 기초과학연구소 1994 基礎科學硏究誌 Vol.5 No.-

The major Chinese herbal medicine stuffs were treated as agricultural products at producing steps but were treated as Chinese herbal medicine stuffs after processing, and so the intervention of middlemen were high and there are severly problems such as rot and low quality because of a long-term multiple-stage distribution. Therefore, to solve these problems must set up new joint markets for Chinese herbal medicine stuffs at city and province, and to reduce multiple-stage distribution structure from farmer to consumer must perform a contract cultivation, and standardization of Chinese herbal medicine stuffs must be performed at an early stage.

The presence of grease and oil(G&O) in the influent wastes to wastewater treatment facility is one of the most serious problems affecting treatment efficiency. If the slaughterhouse wastewater is contained to G&O, pretreatment is required for G&O removal in wastewater treatment. The dissolved air flotation(DAF) has been shown to be efficient process for G&O removal in the pretreatment process. In order to study the optimal operation conditions for G&O removal, the control factors such as type and concentration of coagulant, ratio of pressurized water flow, and pressure are investigated by bench-scale reactor experiment of DAF. The G&O, COD and TOC removal efficiency of FeCl_3 were the higher than those of Al_2(SO_4)_3. The ratio of pressurized water flow was above 0.4 to take 90% or more removal efficiency of G&O. The best operation conditions obtained were 450㎎/l of FeCl_3 dosage, 0.43 of pressurized water flow and 4㎏/㎠ of pressure. The removal efficiency of G&O, COD, TOC and SS in these conditions were 90%, 76%, 80% and 76%.

This study has been made the symbolic meamimg of our traditionl costume colours, based on the theory of yin-yang(positive-active) wu-hsing(five agants). Accoding to the theory of yin-yang wu-hsing, the costume colour has presented our racial sprit, way of thinking, and way of life for a long time, and it has become the traditional culture at last. The order of nature has counterpart in five symbolic custume colours; blue, red, yellow, white, black, the five colurs are called the primary colurs, which produce the compound colurs. The yellow, the red, and the purple have been regarded as the colur of king, queen, and upper classes. Traditional dyeing method are very simple that are traditional custom. The five elements colurs preserving the theory of korean the five elements have been the conception of korean traditional color and they have been developing as the meaning of custom.

The radiative capture theory for both resonant and non-resonant reactions has been developed, which would be even applied to the system with a deformed target having a collective motion. Various radiative capture reactions could be analyzed in terms of the direct radiative capture theory developed, giving the astrophysical S factor, the differential cross sections of emitted gamma rays and life time of compound states. The calculated branching ratio, mixing ratio, capture rates and anisotropy also give informations about the structure of resonant and bound state of residual nucleus.
