이 연구는 문헌 및 현장조사를 통해 동강유역 생태·경관보전지역의 지형·경관 자원을 조사하고 지도화 하였다. 이를 통하여 지형·경관 자원의 분포특성을 살펴보고 동강유역 생태·경관보전지역의 지형·경관자원에 대한 지속적인 관리방안 및 보전방안을 제시하고자 하였다. 연구결과 본 연구지역은 동강 양안의 하천지역 지형·경관자원과 평창군 한탄리의 고원형 카르스트지역 지형·경관자원, 연구지역 전역에 걸쳐 대소로 분포하는 석회동굴 지형·경관자원, 연구지역 경계의 산지지역 지형·경관자원 등 크게 4개의 지형·경관자원으로 분류할 수 있었다. 이들 지형·경관자원은 현재 관광객의 유입과 거주민의 편의성 확보를 위해 일부 훼손되거나 훼손압력이 높은 것으로 조사되었다. 따라서 1일 탐방객을 제한하거나 학술적 의미를 담은 안내판 설치와 같은 지형·경관 자원의 보전과 주민이익이라는 공동 이익 추구를 위하여 지형·경관 자원별로 맞춤식 보전대책이 필요할 것으로 판단된다. This study has focused on geomorphological landscape resources analysis at the Dong-gang River Ecological and Landscape Conservation Area through literature review and field survey. Some appropriate maps have been created for this study. This study intends to examine the distribution characteristics of geomorphological landscape resources at the Dong-gang River Ecological and Landscape Conservation Area, and suggests a solution to manage and maintain the resources. The result has shown that the resources can be divided into four categories : The Dong-gang`s riverside geomorphological landscape resources, Pyeongchang-gun Hantan-ri`s plateau and karst area, limestone caves in various sizes throughout the entire study area, and the mountainous regions close to the study area boundaries. The study concluded that these geomorphological landscape resources are partially damaged or likely to be damaged due to tourist inflow and also the quality of resident lives needs to be improved. Therefore, limiting the number of tourists entering the area or installing guides who provide information about the academic importance of such resources are necessary in terms of maintenance. There is also a need for a customized solution according to geomorphological landscape resources in order to secure benefits for the residents as well.

張東勳,金澈湖 瑞逸專門大學 1991 論文集 Vol.9 No.-

Advertisement plays the importent role of information for both sellers and buyers. Advertisement is therefore an essentional element to successful real estate brokerage operation, too. But there are many differences between the real estate advertising and that of movable estate. I have researched five phases of obtainable effects on real estate advertisement. It turned out that our nations real estate advertisement has low obtainable effects except desire effect and it is analized that the reliance on the real estate is low. The summary of this study is presented as effective advertising of real estate.

위장의 Helicobacter Pylori 감염에 따른 위 점막상피세포의 Nucleolar Organizer Regions : 장형의 위선암종과 비교

장태정,김동훈,배한익 동국대학교 경주대학 1996 東國論集 Vol.15 No.-

1995년 3월부터 1995년 12월까지 동의의료원에서 위내시경 검사로 채취된 위 생검 조지절편에서 위염과 소화성 궤양 및 장형(intestinal type) 위선암종으로 진단된 증례 69예를 대상으로 Helicobacter Pylori(H. pylori)감염에 따른 세포증식능을 조사하고 장형 위선암종의 세포증식증과 비교하였다. 세포증식증은 은염색을 시행하여 AgNORs의수로 표시하였다. 이 중 위선암조은 16예, H. pylori감염 양성은 35예, 감염 음성은 18예 였다. H. pylori감염의 판정은 rapid urease 검사 ( CLO검사), hematoxylin-eosin염색 또는 Giemsa염색으로 하였고, H. pylori감염에 따른 염증반응은 H. pylori의 감염 양성군에서 중등도 이상의 중성구 침윤과 만성 염증세포의 침윤이 각각 82.9%(29/35),65.7%(23/35)였다.(P<0.05). 위 점막상피세포의 지저부 및 협부의 AgNORs갯수는 위선암종에서 4.01±0.50, H. pylori 감염 양성군에서 2.84±0.25, H. pylori의 감염 음성군에서 2.49±0.29 였다(P<0.05).H.pylori의 감염 양성군 및 음성군에서 중성구의 침윤에 따른 AgNORs갯수는 중성구의 침윤이 중등도이상인 경우가 2.80±0.24로써 중성구의 침윤이 없거나 미약한 경우(2.60±0.35) 보다 의의있게 높았지만(P<0.05) 만성염증세포의 침윤에 따른 AgNORs갯수는 유의한 차이가 없었다. 위염의 등급과 위염의 활동성 및 집락의 등급을 합친 위염점수가 높을수록 AgNORs갯수는 증가하는 경향을보였다(r=0.38, P<0.005). 그러므로 H. pylori의 감염이 있으면 위 점막에 염증반응이 생기고 이로 인하여 위 점막 상피세포의 세포증식능이 증가하는데 세포증식의 주 원인은 H. pylori자체일 수도 있고 H. pylori감염에 속발된 중성구 침윤일 수도 있다고 추측된다. The number of silver-staining nucleolar organizer regions(AgNORs) per nucleus has been correlated with proliferative rate and ploidy. The mean AgNOR counts of gastic mucosal epithelium in isthmus or base of nonmetaplastic area were examined in 18 Helicobacter pylori (H.pylori) negative cases, 35 H. pylori positive cases and 16 gastric adenocarcinoma of intestinal type. Acute and chronic inflammation of H. pylori positive cases were more serious than that of H.pylori negative cases(P<O.05). The mean number of AgNORs was 2.49±O.29 for H. pylori negative cases, 2.84±0.25 for H. pylori positive cases, and 4.01±0.50 for gastric adenocarcinoma. The difference among the groups was signiftcant(P<0.05). The mean number of AgNORs for those who showed moderate or severe infiltrate of neutrophil(2.80±0.24) was significantly different from that of patients with absent or mild infiltrate of neutrophi1(2.60±O.35)(P<O.O5). There was no difference of mean AgNORs counts according to chronic inflammatory cell infiltrate. A positive association between mean AgNORs counts and gastritis score was prescnt(r=0.38, P<O.OO5). The alteration of replication cycle of gastric mucosal epithelium may be caused by H. pylori infection or neutrophil.

아급성 Ethanol 중독시 고뇨산혈증에 미치는 Pyrazinamide의 영향

장윤경,강우규,김동훈,최종원 慶星大學校 環境問題硏究所 1992 環境硏報 Vol.2 No.1

Ethanol 투여후 pyrazinamide 처리로 유도되어지는고 뇨산혈증의 발생 기전과 규명하고자 ethanol을 rat에 아급성적으로 투여하고 pyrazinoic acid의 대사 과정, 뇨산의 혈증 농도, 뇨산의 생합성 및 분해과정에 관여하는 효소의 활성 변화를 비교검토하였을 때 pyrazina-mide의 대사산물인 pyazinoic acid의 생성과정은 증가되었으나 pyrazinoic acid의 분해과정은 영향이 없었다. Ethanol 아급성 중독상태에 pyrazinamide를 투여하였을 때 혈액중의 뇨산 농도는 대조군에 비해 약 123% 정도현저히 증가되었다. 뇨산의 분해 효소인 urixase의 활성변화와 생합성에 관여하는 adenosine deaminase, purine nucleoside phos-phorylase 및 guanine deaminase의 활성변화에는 별다른 관련성이 없었으며 선책적으로 xanthine oxidase 활성만이 유도되어 나타나는 결과였다. In the present work, the purpose was to onbserve the effect of subacute ethanol intoxication on the changes of purine metabnolic pathway after pyraxzinamide administration in rats. In vitro test, it was observed that pyrazinamide deaminasing-enzyme activity was significantly increased and pyrazinoic acid oxidizing-enzyme activity was not affected by ethanol-administrated rat's cytosolic liver. When uric acid level in blood was estimated after pyrazinamide treatment, the blood level was increased in comparison to control group of subacute ethanol intoxication. Ethanol administration did not affect activities of guanine deaminase, adenosine deaminase, purine nucleoside phosphorylase and uricase, on the other hand, xanthing oxidase activity was significantly increased as compared with control. These results suggest that hyperuricemia incuced by the administration of pyrazinamide after subacute ethanol intoxication may be result from the selective increase of xanthine oxidase activity.

This study was investigated the application and kinetics of biofiltration using cometabolic process to remediate gaseous toluene that are highly recalcitrant to adsoption and biodegradation. Biofiltration was successfully applied to treat amixture of volatile organic compounds(Toluene) from contaminated air stream. Immobilized Ps.oleovorans biofilter was evaluated for its value in simultaneous removal of Toluene from waste air stream. In the loading rate (1,000ppm) and space velocity(1,200hr). the average removal efficiencies of Toluene were 33.7%. and CO2 production rate were 5.28㎎/hr

관수된 충전칼럼에서의 압력손실

In this work, an equation for determining the pressure drop of irrigated packings is introduced. This is built up from the well-known channel model. It is valid for the whole load range up to the flooding point. To apply the pressure drop formula, it is necessary to know the operating conditions, the liquid hold-up and the from factor μ specific to the packing element or group of packings. The method of calculating the pressure drop is illustrated by means of an example 1) The agreement obtained between the calculations and the experiments is regarded as good. As expected, the measurements below the loading line are reproduced more exactly-the average error ￣δ₁(△P/H) in Table l(a)-(c) is considerably less than 10%. The measurements above the loading limit including the pressure drop at the flooding point are reproduced with an average relative error ￣δ₂(△P/H) of about 15%. 2) Another advantage of the method chosen here the represent the pressure drop is that, by means of a packings element constant μ characteristic of almost every family of packing elements or group of packing elements of similar construction, it is easy to compare the pressure drop of the particular type of packing element and its height with other packing elements. The advantage of this model is that know-ledge of the dry pressure drop of the packing is not necessary. To reinforce the above dependences a numerical example is added with the help of which the determination of the pressure drop is demonstrated.
