Lao People's Democratic Republic(PDR) is one of the "least developed country" from the standpoint of the United Nations definition. It is a landlocked country with an area of 236,800㎢ in Indo-China Peninsula. Moutains covered with tropical forests occupy two-third of the surface area. The moutains are inhabited by various hilltribe groups practicing slash and burn agriculture(as it were shifting cultivation). Forest destruction and land degradation have resulted from shifting cultivation. The major problems faced by government are converting shifting cultivation to permanent croplands and increasing land productivity and product yield by effective watershed management. Thus, a more detailed analysis of the shifting cultivation areas. through the use of spatial data or satellite imagery and GIS, is needed. However, local governments have no computer facilities and technical capability to use remote sensing and GIS technology. Thirteen thematic maps were completed with the data such as aerial photos, MOS-1 satellite image, existing topographic maps and Arc-Info System for Nam khane watershed area, the subject of this study. Data overlay of each data layer is very useful for effective watershed management. And also land-use suitability map will be produced from the base of each data layer. It is clarified that GIS is very useful to prepare the thematic maps for spatial analysis which have no spatial data and no computer facility and technical power, further more, remote sensing is also useful for the inaccessible area.

피혁폐수의 수질오염 현상에 관한 고찰

조명찬,노병일,신춘환 동서대학교부설연구소 1997 연구소 논문집 Vol.2 No.-

피혁의 최종처리공정 중 코딩공정은 피혁제품의 품질을 결정하는 중요한 기술로 자리잡고 있다. 피혁 코팅에 사용되는 수지들은 분산매의 종류에 따라 유성 Polyurethane(PU) 계열 및 수성 PU계열로 크게 구별되며 근래에 와서는 작업환경의 개선 및 환경오염 방지 측면에서 수용성 PU의 사용이 보편화 되면서 이들의 수질오염에 미치는 영향을 제시할 필요성이 대두되었다. 따라서 본 실험에서는 수용성 PU가 수계에 유입되었을 경우 COFD, BOD, SS의 상승효과를 측정함으로써 기초자료로 활용하고자 하며 특히 수용성 PU는 polyol 및 diisocyanate의 중 부가반응에 의해 생성되는 고분자 물질로서 수중에서는 분자 Chain이 절단되는 aging effect현상이 현저할 것으로 예상하여 수용성 PU가 유입된 수계의 aging effect와 BOD 및 COD와의 상관성을 도출하여 방류수 처리의 기초자료로 제공하고자 한다.

Andre´ Malraux의『lLa voie royale』에 나타난 작가의 비젼과 회화적 글쓰기

조종권,서명숙 부산대학교 사범대학 1992 교사교육연구 Vol.25 No.-

Malgre´ tant d'e´tudes sur Andre´ Malraux, il semblerait que les recherches sur la relation organique entre ses romans et ses e´crits sur l'art ne sont pas suffisantes. De plus, en niant l'autonomie temporelle et spatiale de la peinture. Malraux dit que l'oeil du romancier est plus apparente´ a` le´cran qu'au tableau. Voila` les raisons qui motivent notre e´tude. Dans cette recherche, nous posons donc deux questions : d'abord, est - ce qu'il y a une rupture absolue entre ses mondes romanesque et artisque? Sinon, quelle est l'influence mutuelle de ces domaines differents? Ensuite, est - ce qu'on peut generaliser sa remarque sur la difference entre le roman et la peinture? Si, au contraire on eput trouver une analogie, au moins chez lui, quelle est - elle? Pour ve´rifier ces doutes - la`, nous commencons par examiner la vision malucienne, poisque c'est la vision du romancier qui lui permet decrire. Comme texte, nous choisissons 『La voie royale』 qui a e´te´ concue et e´bauche´e´ avant 『Les conque´rants』et est conside´re´e´ comme son premier roman. Aux yeux d'Andre´ Malraux, notre monde est tout ferme´ comme une prison dans laquelle les prisonniers que nous sommes souffrent de leur condition d'hommes avec leurs espoirs pourris. Dans 『La voie royale』, cette prison est de´crite avec son imagination visuelle tre`s riche. La fore^t, les Moiˇs et la mort sont les prisons les plus dures dans ce roman et chacun de ces espaces ferme´s a son image visuelle caracte´ristique, par exemple, les grilles, le mur, la corde du prisonnier etc. Avec cette facon de voir, l'auteur e´crit son roman comme le peintre dessine. Voici quelques traits caracteristiques de son e´criture picturale. Premie`rement, il regarde et de´crit son objet presque toujours dans un cadre. En plus de la porte, la fene^tre, la vitre, le hublot et la de´chirure des feuilles, il utilise tre`s souvent les miroirs et les jumelles. C'est un encadrement qui est la base de la composition picturale de la peinture occidentale et qui donne aux lecteurs des images centre`es et tendues chez Malraux. Deuxie`mement, on remarque que l'auteur re´ve`le particulie´rement le changement des couleurs par suite du jeu de lumie`re et d'ombres. C'est aussi un trait qu'on retrouve dans la peinture impressionniste. Troisie`mement, on trouve dans son ectiture le regard du peintre qui pe´ne`tre l'objet et decouvre une mobilite immobile, c'est-a-dire une temporalite latente que l'auteur lui-me^me n'a pas approuve´e. Finalement, on expose son e´criture impressionniste la plus typique qui est une description des impressions, par exemple, l'e´criture de l'objet dans l'ordre de sa perception, non pas d'apre`s sa connaissance et son raisonnement. A la suite de cette petite e´tude, on peut conclure qu'Andre´ Malraux regarde et e´crit avec l'oeil et la touche d'un peintre.

Through the ISODATA method, the micro-landform of Julpo-Bay tidal flat was classified into mudflat, mixedflat, and sandflat using Landsat TM image. Each showed an apparent differences in its topographical characteristics and grain size composition. Mudflats are formed with flat faces and tidal channel of dissected gully. Its characteristics of grain size analysis that the grains have less than mean grain size 4 phi. Its sorting is bad (higher than 1 S.D.), and it showed strongly positive skewness. But sandflat is topographically flat without tidal channel. It has developed with ripple marks. Accdording to the grain size analysis of deposits, the soil is coarse size with 90% of sand and its sorting is well(lower than 1 S.D.) Also, it showed strongly negative skewness. Mixed flat is in between mudflat and sandflat in its characteristcs.

In order to investigate the change of physicochemical properties of ginseng root starch during storage and heat treatment. the roots were stored for 15 days at 5℃, 15℃, 30℃ and 45℃, and heated for 15 hours at 60℃, 70℃, 80℃, 90℃, respectively. The starch content was decreased from about 40% to 23-26% and sucrose content was increased from 4% to 12-16% during storage for 15 days at 5-45℃. Maltose, which was not detected in fresh samples, was increased upto 8.5% during storage or heat treatment. Granular size of the starch was decreased and some of the granules were broken during storage. Amylose content in the starch was decreased from 33% to 20%, and blue value and alkali number of the starch were increased slightly, and solubility and swelling power of the starch were decreased during storage. The higher storage temperature and the longer storage time, the starch was more susceptible to gelatinize, and the viscosity of the starch was lowered with the susceptibility of gelatinization. The susceptibility of degradation of the starch by the amylase was increased and amylolytic activities in ginseng root were, also, increased during storage.

조명훈,윤영주,김광원 대한치과교정학회 2001 대한치과교정학회지 Vol.31 No.1

교정력을 가한 후 각기 다른 재료로 제작된 고정성 보정장치를 적용한 경우에 발생하는 치주조직의 재형성과 치유과정을 조직학적으로 관찰하기 위해 건강한 치주상태를 가진 네 마리의 유성견을 대상으로 최초 교정력이 200gm이 되도록 견인 스프링 (sentalloy closed coil springR, Tomy Co., Japan)을 대상 치아에 결찰하여 1주일 간 교정력을 가한 후, 각각의 실험동물에 3가닥 호선인 0.018인치 DentaflexR(Dentarum Co., Germany), 3가닥 호선인 0.020인치 DentaflexR(Dentarum Co., Germany), 6가닥 호선인 0.0195인치 RespondR(G&H Co., U.S.A.)를, 그리고 자가중합형 레진 접착제인 Superbond C&BR를 고정성 보정장치의 재료를 이용하여 보정장치를 접착한 군과 보정장치를 접착하지 않은 군으로 나누어 3주간 적용 후 희생하여 H-E염색군, M-T염색군으로 나누어 광학현미경으로 관찰하여 다음과 같은 결과를 얻었다. 1.0.0195인치 RespondR를 접착시킨 군은 0.018인치 DentaflexR, 0.020인치 DentaflexR, Superbond C&BR를 접착시킨 군에 비교할 때 압박측에서의 거대세포 침윤 감소와 긴장측에서의 신생골 형성 증가가 매우 두드러지게 나타났으며 치주인대는 형태와 배열에서 대부분 정상적인 소견을 보였다. 2.실험 1군의 모든 실험대상에서 압박측 치조골 내부의 괴사골이 관찰되었고, 압박측과 긴장측 모두에서 치조골 표면의 골양조직 및 sharped 섬유의 형성과 치주인대의 재형성 현상이 나타나는 것이 관찰되었다. 3.실험 2군은 실험 1군에 비교하여 압박측에서 거대세포 침윤이 현저히 감소되었고 치주인대는 거의 정상적인 소견을 보였다. 긴장측에서는 수층의 골침착을 보이며 치주인대 측으로 골양조직과 골아세포가 구상으로 나타나는 활성화 소견을 보였다. 이상의 결과에서 더 여러 가닥이 꼬인 6가닥 호선인 0.0195인치 RespondR(G&H Co., U.S.A.)를 보정장치로 적용한 경우가 다른 재료의 고정성 보정장치보다 더 활발한 신생골주 형성의 활성화 소견이 관찰되었으며 대조군과 유사한 배열과 형태를 보이는 정상적인 치주인대 섬유의 배열양상이 관찰되어 다른 재료들에 비교하여 치주조직의 초기 재형성과정을 더 신속하게 유도하는 것으로 사료된다. The purpose of this study was to evaluate the material for fixed type retainer, allowing physiologic tooth movement. and proper remodeling of periodontal tissue during retention period. The present study was performed to observe the histologic changes of periodontal tissue after application of different types of fixed type retainer after orthodontic tooth movement in young adult dogs. For this study, 4 young adult dogs were used as a experimental animal and experimental group was divided into three groups ; experimental group 1 contained right side maxillary third incisors and canines, experimental group 2 contained contralateral teeth of same animals, and control group contained mandibular premolars. And each dogs were applied the 4 different types of fixed type retainer to experimental group 1. The experimental teeth were ligated on the Sentalloy closed coil springR(Tomy Co., Japan) from maxillary third incisors and canines and applied orthodontic force at initial 200gm-forced during 1 week. All the experimental animals were sacrificed on the 3rd week after the orthodontic teeth movement and then the specimens were taken, fixed in formalin, embeded in parafin, sectioned 6-8μm in thickness and stained with Hematoxylin-Eosin staining, and Masson's trichrome staining method. Examined under the light microscopy. The following results were observed. There were observed that decreased infiltration of giant cells in pressure side and increased the new bone forming in tension side on the specimen of 6-stranded 0.0195' RespondR(G&H Co., U.S.A.) group. Periodontal ligament fibers were much compressed or elongated in 3-stranded 0.018', 0.020' DentaflexR(Dentarum Co., Germany), and Superbond C&BR(Sun Medical Co., Japan) groups. 2. In experimental group 1, necrotic bone inside the alveolar bone of pressure side, forming of the sharpey's fiber in osteoid tissue, and remodeling of the periodontal ligament were observed in all animals. 3. In experimental group 2, it was observed that the amount of bone resorption was equal or decreased in pressure side, and increased new bone forming and significantly decreased Infiltration of giant cell than the experimental group 1. By this results, it considered that 6-stranded RespondR(G&H Co., U.S.A.) wire was the most useful material allowing early periodontal tissue remodeling.

인공 및 천연 CaCO₃의 염료흡착 특성

조명찬 東西大學校 2000 동서논문집 Vol.6 No.-

원주의 가공기술을 개발하기 위한 초기 연구로써 진주 층 및 삽입 핵(CaCO3)을 사용하여 염료의 흡착 특성을 조사해 보았다. 진주 염색에 사용되는 것으로 알려져 있는 Rhodamine 6G, Rhodamine B, Methylene Blue를 염료로 선택하여 물, 메탄올, 에탄올, 아세톤 등의 용매를 사용하여 용해시킨 결과 염료용액 제조시 염료의 용해도로 인한 문제는 없는 것으로 판단되었다. 진주 층과 삽입 핵(CaCO3)을 60 micron크기로 파쇄한 후 Porosimeter를 사용하여 기공크기 면적과 내부표면적을 측정해 보았다. 측정 결과 기공크기, 기공체적, 내부표면적은 진주 층의 경우 대략 100 Å, 0.035 cm3/g, 1 m2/g, 삽입 핵은 대략 200 Å, 0.0116 cm3/g, 2m2/g 정도인 것으로 나타났다. Rhodamine 6G를 염료로 사용하여 진주 층과 삽입 핵에의 회분식 흡착 실험 결과 대략 20시간과 30시간 후에 각각 평형에 도달하는 것으로 나타났다. 평형 흡착 능의 경우 삽입핵에의 흡착 량은 진주 층에의 흡착 량의 약 20%에 해당되는 것으로 나타나 진주 핵에도 염료가 일부 흡착된다는 사실을 확인하였다. 탈착실험 결과 탈착률은 대략 13% 정도로 동일하나 삽입 핵의 탈착 평형 시간은 대략 10시간 정도로 진주 층의 50시간에 비해 5배 빠른 것으로 나타났다. This study represents characteristics of dye adsorption onto pearl and pearl nucleus (CaCO3). Three basic dyes such as Rhodamine 6G, Rhodimine B, and Methylene Blue were selected as model compounds for adsorption experiments because they were known to be used for processing pearls. Solubility of the dyes were investigated with various solvents such as distilled water, methanol, ethanol, and acetone and were found to be out of the range of precipitation. Pearl and pearl nucleus were reduced to powder of 60 ㎛ size and the pore characteristics of the powders were investigated using porosimeter. The pore size, pore volume, and surface area were found to be approximately 100 Å, 0.035 cm3/g, 1 m2/g for pearl and 200 Å, 0.0116 cm3/g, 2m2/g for pearl nucleus. From the batch adsorption experiment using Rhodamine 6G, it was found that equilibrium reached after 20 hours for pearl and 30 hours for pearl nucleus, respectively. Adsorption loading for pearl was 5 times larger than that for pearl nucleus. Desorption experiment showed that desorption percent was 13% for both adsorbents. However, time for desorption equilibrium for pearl nucleus was 10 hours and was 5 times shorter than that for pearl.

조효정,정장표,박명호,이승훈 慶星大學校 環境問題硏究所 1996 環境硏報 Vol.6 No.1

The air quality has been deteriorated dux to the rapid industrialization and the increase of traffic volume. Especially, the concentrations of air pollutants of Saha-Gu including Shinp'yong-Jangrim industrial complex showed severe air pollution level compared to other districts in Pusan. To establish proper and comprehensive cnntrol strategies for the reduction of air pollutant levels, the information on the emission quantities of air pollutants are necessarily needed. Although there are a few data on the emissions of air pollutants of various sourxes, the data have not been used enough dux to the deficiency of quality and content. Therefore, it is nexessary to establesh the data system of emission inventory for the purpose of being used in air quality management. In this study, the database program of emissions inventory was made using the clipper version 5.2 program. The major functions of datavase program are to estimate the emission quantities and contributions of air pollutants by the grid, the source scale, the source type, and the season in Saha-Gu.
