경기도 광릉의 주엽산 일대의 삼림토양을 대상으로 5개의 정점을 설정하여 토양의 환경요인과 토양미생물의 군집규모를 조사하여 토양미생물의 토양생태계內의 기능을 토양의 환경요인과 상호 관련지어 해석하는 한편, 미생물의 개체군증식에 미치는 환경요인을 규명하는 미생물 생태학적인 연구를 실시하였다. 그리고 S/O value와 섬유소 분해 미생물 군집 크기 사이의 상관지수를 구하여, 토양생태계 內의 구조 및 기능 해석을 위한 새로운 biological index로서 S/O value가 적용 가능한 지를 조사하였다. 그 연구결과를 요약하면 다음과 같다. 1. 토양미생물의 군집 규모는 상층이 하층토양에 비하여 컸다. 또 토양미생물 군집의 규모를 세가지 유형으로 구분할 때, 일반세균>방선균류>일반균류의 순으로 군집의 크기가 확인되었으며 토양 內의 유기물 분해에 기여하는 작용도에 있어서도 그 순위가 동일하였다. 섬유소 분해능을 지닌 미생물 군집의 비율은 일반세균의 경우 75.8%, 방선균류는 81.2%, 일반균류는 54.5% 정도가 되어 매우 높았다. 한편 세균류와 균류의 개체군 규모는 3:1의 비를 나타내었다. 2. 실험대상지역의 토양 pH는 5.2∼5.7범위였으며, 토양 온도 및 무기이온의 함량은 일반적으로 상층이 높은 값을 나타내었으나 함수량은 하층이 높은 값을 보였다. 환경요인중 개체군 증식에 기여하는 영향이 가장 큰 parameter는 pH로 추정되었는데, 함수량, ??이온의 함량도 어느정도 영향력을 미치는 것으로 추정되었다. 3. 환경요인의 분석에서 수용성 당류, 아미노산의 함량은 상층이 하층에 비해 높았으나 총 유기물함량은 수직적으로나 정점별로도 유의한 차이는 없었다. 4. S/O value는 개체군 규모가 클수록 높았다. S/O value와 섬유소 분해 미생물 군집의 크기 사이의 상관지수는, S/O value와 총 섬유소 분해 미생물 사이에서 0.769, 일반 섬유소 분해 세균과의 경우 0.700, 방선균류 0.788, 일반균류는 0.576으로 나타나, 상당히 유의한 상관관계가 있었다. 5. 토양의 textile을 예견할 수 있는 균사체 발달 정도는 천이과정 중의 정점에서, 극상단계에 거의 도달한 정점에 비하여 양호하였다. 6. 실험대상지역의 토양생태계는 생물군집 중 미생물 군집의 규모 수준에서 고찰해 볼 때 극상단계에 도달한 것으로 판단된 정점도 실질적으로 아직 천이과정 중인 생태계로 판명되었다. The authors surveyed around Mt. Choo Yub in Kwang Reung on April 14th in 1983 and examined both environmental factors and microbial population size including the cellulolytic microbes in soil. In order to elucidate the relationship between soil environmental factors and the function of soil microbes in the soil, and to examine the environmental factors affecting to the microbial population size, this research was carried out. And calculated the correlation coefficients between S/O value and population size of cellulolytic microbes, S/O value was examined to be applied as new biological index for analysis of structure and function in soil ecosystem. The results of this experiment are summarized as follows. (1) The population size of soil microorgasms in surface layer was larger than that of lower layer. Subdivided the microbial community in the soil into three groups such as general bacteria, actinomycetes and general fungi, the population sizes and the activity in degradation of organic substances were large in order of general bacteria, actinomycetes and general fungi, respectively. Composition of cellulolytic microbes in subdivided microbial group was high as much as 75% in bacteria, 81.2% in actinomycetes and as 54.5% in fungi. The ratio of bacteria to fungi was 3:1. (2) PH value of the experimental soil was generally the range of 5.2∼5.7, the temperature of surface layer was higher about 5℃than that of lower layer. The amounts of inorganic components such as ??, ??, ??, ??, ?? were more accumulated in surface soil than those of lower layer. It is postulated that the parameter affecting strongly to the population size is pH among the various environmental factors. In addition, the moisture content and the amount of ?? were also related with the population size of soil microbes, to some extent. (3) In the analysis of organic substances such as free amino acid, soluble sugar and total organic matter, the amount of free amino acid and soluble sugar in surface layer were higher than those of lower later, but the amount of total organic matter has no significance in the sense of amounts between surface layer and lower layer. (4) The S/O value(amount of soluble sugar/amount of total organic matter) in soil was high in accordance with increase of the population size. And the correlation coefficients between S/O ratio and population size of cellulolytic microbes were shown such as 0.769, 0.700, 0.788, 0.576 respectively, in total cellulolytic population size, general bacteria, actinomycetes and general fungi. That is to say, it is significantly correlated between S/O ratio and population size of cellulolytic microbes. It was considered that S/O value can be adapted as a useful biological index for interpretation of the function and structure in soil ecosystem. (5) Mycelial extension to predict the textile of soil is more active in successional ecosystem than in the almost matured climax ecosystem. (6) The ecosystem of experimental area referring to the level of microbial population size experimental area is actually postulated successional ecosystem.

Regarding to the ecotourism for environmental conservation, tourists's consciousness and attitude on environment should be dealt with importantly more than the mass tourism. The purpose of this study is to identify the effects of the tourist's environmental consciousness on the ecotourism attitudes. As a result, it was analysed that the more people had interested in environmental problems, positive activities in the environment, the more people had the ecotourism attitudes. This suggested that for development of the ecotourism, it were needed to change tourist's attitude to friendly environment, to make higher consciousness about environmental conservation.

Objectives: Symptoms arising from spinal cord tumor are often insidious in onset and nonspecific in nature. To make the subtle initial signs and symptoms of these tumors more apparent to clinicians, we retrospectively analyzed the data of spinal cord tumor patients who were misdiagnosed as degenerative spine disease. Methods: We reviewed history, symptom, sign, radiological study, and pathologic diagnosis of 19 spinal cord tumor patients who had been operated as degenerative spine disease, especially duration and description of symptoms and sign before an accurate diagnosis was made. Results: Average duration of delay before an accurate diagnosis was made was 178.4 days(range: 23~303). Common symptom and signs on neurologic examination included aggravation of pain(8 cases; 47.1 %), and neurologic decline(9 cases; 52.9%) The misdiagnosis included a herniated lumbar disc(16 cases; 94.1%), lumbar stenosis(1 case; 5.9%). Inappropriate treatment for these misdiagnoses included 5 percutaneous lazer discectomies, 9 discectomies, 3 chemonucleolysis, 2 posterior lumbar interbody fusions with cages. Conclusion: When a patient has symptoms that appear to be out of the ordinary, surgeons should suspect other spinal disease including the spinal cord tumor.

근관내 여러 조건에서의 ROOT ZX 전자근관장 측정기의 정확성에 관한 연구

조용범,홍한표,홍찬의 단국대학교 치의학연구소 1994 논문집 Vol.6 No.1

The technique of electronic working length determination has gained considerable popularity among both endodontists and general dentist. Recently, the Root ZX(J.Morita Corp., Tokyo, Japan) has been developed with unique electronic features that are claimed to maintain the instrument's accuracy regardless of canal condition. The purpose of this study is to compare the accuracy of the Root ZX with estimates of actual canal length, in vitro model and in vivo under the various condition. 1. The experiment in vitro model 50 extracted, single-rooted and single-canaled, teeth with mature apices were selected. The extirpated teeth were placed in a saline-soaked Oasis, and measured with Root ZX according to manufacturer's instruction in the dried canal and saline-irrigated canal. The teeth were then removed from the model and the actual canal length was measured. The values of canal length in each conditions were used for evaluating the results. 2. In vivo study 15 teeth which destined for extraction were selected. Once access was gained, the canals were irrigated using 5.25% sodium hypochlorite and were not dried prior to insertion of the measurement file. Once the Root ZX indicated the C-D junction, self-curing resin was injected into the canal. The tooth was extracted and ground with a bur and Soflex disk. This was done until the terminus of the file and the root was revealed. The distance from the end of the file to the foramen(major diameter) was measure, and evaluated. The results were as follows: 1. In vitro study(A/B : difference between A and B) 1). The mean values of acutal length/dried canal length and actual length/saline irrigated canal length were 0.528㎜, and 0.525㎜ respectively. There is no significant difference between the means of acutal length/dried canal length and actual length/saline irrigated canal length. 2). Root ZX could locate the C-D junction at the point of 0.5㎜ inside of major foramen, in both dried canal and saline-irrigated canal. 2. In vivo study 1). Root ZX could locate the the C-D junction at the point of 0.5㎜ coronal to the major foramen in presence of 5.25% NaOCl. 2). Root Zx located a point that was perceived to be the apical constriction. The majority of file tip experimented were within the canal, not extended beyond the major foramen.

1. 목적 전이성 방광 이행 상피 세포암의 경우에 시행될 수 있는 몇가지 전신적 항암 요법 중 M-VAC 병용 투여가 가장 인정받고 있는 항암 요법이긴 하나 일시적 반응 후 재발시 즉 M-VAC 병용투여에 불응하는 경우 증상 완화 요법(palliative therapy) 이외에 다른 치료 방법이 없었다. 저자들은 M-VAC 병용 요법에 불응하는 전이성 방광 이행상피 세포암 환자 2례에서 기존 M-VAC 항암 화학 요법보다 항암제 투여량을 증량한 M-VAC 항암 요법을 시행하였다. 2. 방법 기존 M-VAC 항암 화학요법용량(Methotrexate 30㎎/㎡, Vinblastine 3㎎/㎡, Adriamysin 30㎎/㎡, Cisplatin 70㎎/㎡)보다 항암제 용량을 증량하고(Methotrexate 30㎎/㎡, Vinblastine 4㎎/㎡, Adriamycin 60㎎/㎡, Cisplatin 100㎎/㎡) 이로 인한 골수 저하증을 예방하기 위하여 GM-CSF를 동시에 투여하였다. 3. 결과 증례 1 환자는 중량 항암 화학 요법 1개월 후 추적검사에서 전이된 임파절이 모두 소실된 완전 관해를 보였으며 증례 2 환자는 증량 항암 요법 후 14일째 폐혈증으로 사망하였다. 4. 결론 증량 M-VAC 항암 화학 요법은 아직 시행 기간 및 증례가 많지 않아 완전 관해 기간 및 적절한 항암요법 시행 횟수의 미확립, 항암제 치료 도중의 치사율의 감소등이 문제점으로 지적되고 있으나 기존 M-VAC 항암 요법에 불응하는 전이성 방광이행 상피 세포암 환자에서 우선 고려될 수 있는 치료법으로 사료된다. Background : M-VAC(methotrexate, vinblastine. doxorclbicin, cisplatin) chemotherapy is the most common and effective treatment modality for advanced transitional bladder tumor. However, there is no effective therapy in case of the patients nith bladder tumor refractory to M-VAC chemotherapy. Methods : Two male patients mith metastatic transitional bladder tumors refractory to conventional chemotherapy with methbtrexate, vinblastine, doxorubicim, and cispiatin (M-VAC) were treated with escalate3 dose of M-VAC plus recombinant human granulocyte-macrophage colony stimulating factor (rhGM-CSF). Formula of escalated M-VAC chemotherapy were 30mg/m^(2) of inethotrexate, 4mg/m^(2) of vinblastine. 60rmg/m^(2) of doxorubicm, and 10Omg/m^(2) of cisplatin, and 250mg/m^(2) rhGM-CSF per day administered subcutaneously (SC) for 10 consecutive days. Result : One of the treated patients mas responded with complete remission and the other one m-as dead by sepsis on post-escalated M-VAC chenctherapy 14 days. Coclusion : We believe escalated M-VAC chemotherapy may be one of the effective alternative treatment for patients with metastatic urothelial tumor refractory to conventional M-VAC chemotherapy.

These days professional Ssirum s the most traditional wrestling which has been famous in Korea and has shown korean nationality. However Sisirum is inferior to other professional sports, that is, professional baseball, professional football, professional basketball. The purpose of this study s that we would like to make people have understanding of the reality of korean Ssirum in these days and then suggest some plans for solving the problems which Sisirum has had. We should lead more people than earlier to visit stadiums to watch Ssirum match, because Sisirum has not been more popular than other professional sports. For this, we should offer something to enjoy and cause people to enjoy games. Therefore this kind of pleasure helps them visit Sisirum matches. To reach our goals, we would like to analyse web sites and homepages of many different professional Sisirum teams and compare their web sites. Increasing fan's interest in Sisirum s the most important thing to manage the professional Sisirum team. Also, effective activities of public relation could lead the companies which have professional Sisirum to improve their images. In this points we would like to suggest these following plans. First, professional Sisirum team should offer various service on-line or web sites. Second, professional Ssirum team should build up the newest and the most effective web sites in the relation to other companies to improve companies' image. Third, more intriguing events than other professional sports must be serviced.

Abstract-In an attempt to elucidate the anti-inflammatory action of ginseng total saponin, protopanaxadiol and protopanaxatriol, the anti-inflammatory activity of three compounds was investigated under various acute and chronic inflammatory models. The blood vessel permeability was slightly inhibited by total saponin and protopanaxatriol treatments. Granuloma formation induced by 2% carrageenan was inhibited by total saponin and protopanaxatriol. The cotton-pellet granuloma formation was significantly inhibited by intraperitoneal injection of total saponin. Total saponin and protopanaxadiol inhibited leukocyte emigration and protein exudation in CMC-induced pouch but protopanaxatriol increased leukocyte emigration. The swelling of rat hind paw induced by 1% carrageenan was significantly inhibited by total saponin, protopanaxadiol and protopanaxatriol both single and 2 weeks treatments. Total saponin, protopanaxadiol and protopanaxatriol decreased the anti-inflammatory activity in adrenalectomized rat. Our results suggest that total saponin, protopanaxadiol and protopanaxatriol have potent anti-inflammatory activity, this may be mediated in part through stimulation of adrenal glands.
