1985년 4월부터 1987년 5월까지 7회에 걸쳐 영산호수계의 7개 調査地点에서 영산호 수질에 대한 이화학적 조사를 실시하였다. 투명도는 0.2∼1.9m의 변화폭으로 매우 혼탁한 상태였고 pH는 5.9∼8.2 범위로, alkalinity는 표층이 22.2∼59.4㎎/ℓ 저층이 18.5∼159.1㎎/ℓ, 염분도는 0.0∼1.6‰의 범위였으며 저층이 표층에 비해, 또한 하구둑부근의 하류에서 湖의 상류지역보다 높았다. 전기전도도는 표층이 87∼800㎛hos/㎝, 저층이 102∼5300㎛hos/㎝로 상·하류간의 변화가 염분도와 유사한 경향을 보였다. DO는 1.70∼13.99㎎/ℓ로 층별, 계절별에 따라 큰 변화를 나타냈고 COD의 값은 표층이 1.9∼6.6㎎/ℓ, 저층이 1.4∼7.3㎎/ℓ으로, BOD는 표층과 저층이 각각 0.5∼4.8㎎/ℓ, 0.6∼3,8㎎/ℓ 범위에서 변화하였으며, 영산호에 유입되는 유기물질 부하가 계절적으로 심하다는 것을 알 수 있었다. 표층과 저층에서 NH₄( )-N량은 각각 10.0∼205.0㎍/ℓ, 10.0∼260.0㎍/ℓ의범위에서, NO₃( )-N은 8.0∼309.0㎍/ℓ, 8.0∼316.0㎍/ℓ의 범위에서, NO₂( )-N량은 1.0∼18.0㎍/ℓ, 1.0∼21.0㎍/ℓ의 범위에서, PO₄³( )-P량도 1.0∼84.0㎍/ℓ, 1.0∼118.0㎍/ℓ으로 조사시기와 층별 그리고 조사지점에 따라 차이를 나타냈다. Physicochemical water quality of Yongsan Lake was studied at seven stations from April, 1985 to May, 1987. Transparency in the lake showed variation range from 0.2 to 1.9m and the lake was extremely turbid. Variation in pH ranged from 5.9 to 8.2 and alkalinity varied widely from 22.2 to 59.4㎎/ℓ in surface layer and from 18.5 to 57.1㎎/ℓ in bottom layer of the lake. Salinity varied from 0.0 to 1.6‰. The salinity of bottom layer was higher than that of surface layer and the salinity value of the downstream was higher than that of upperstream of the lake. Conductivity varied from 87.0 to 800㎛hos/㎝ in surfce layer and from 102.0∼5300.0㎛hos/㎝ in bottom layer. The variation of conductivity was similar to the case of salinity. DO contents in the lake showed extremely high variabilitydepending on months and layers of the lake, variation ranged from 1.7㎎/ℓ to 13.99㎎/ℓ. The value of COD varied from 1.9 to 6.6㎎/ℓ in surface layer and from 1.4 to 7.3㎎/ℓ in bottom layer. BOD of the lake was variable depending on the seasons and stations. BOD values ranged from 0.5 to 4.8㎎/ℓ in surface layer and from 0.6 to 3.8㎎/ℓ in bottom layer. COD and BOD variability from the results inidicated that the lake was generally high in organic matter loading. In surface layer and bottom layer of the lake, the content of NH₄( )-N were varied from 10.0 to 205.0㎍/ℓ and from 10.0 to 260.0㎍/ℓ, respectively, those of NO₃( )-N, from 8.0 to 309.0㎍/ℓ and from 8.0 to 316.0㎍/ℓ, respectively, those of NO₃( )-N, from 1.0 to 18.0㎍/ℓ and from 1.0 to 21.0㎍/ℓ, respectively and those of PO₃³( ) -P, from 1.0 to 84.0㎍/ℓ and from 1.0 to 118.0㎍/ℓ, respectiely. All of these nutrients of the lake were highly variable depending on the seasons and layers as well as stations.

Soft tissue defects in oral & maxillofacial region caused by tumor resection, trauma, congenital deformities have been treated in autogenous soft tissue flap, allogenic material, free dermal graft, fascia graft. Of these methods, autogenous dermis graft had initially been applied in hernia treatment at the beginning of nineteenth century and have been applied in soft tissue augmentation coverage of vital structure, dead space removal and reconstruction of fascia. A fat graft is used in reconstruction of orbit at the enucleation, restoration of facial contours, etc. In this case, patient with chin soft tissue defect in traffic accident was treated in autogenous dermis-fat graft from patient's abdominal and gluteal region. Chin defect was recons ructed favorably. There was no severe atrophy of grafted area 12 months postoperatively. We will report the result that is favorable esthetically with literature review.

The government of the Republic of Korea has been actively engaged in the process of national developm ent over the past two decades and has accomplished great development in many fields, especially in industry, and national defence. As the result, the industrial and occupational structures have been changed into highly sophisticated ones, and the national standard of living also has been upgraded. In the process of that change, higher education has been the most influential agent. Higher education itself also has developed, particularly in terms of quantitative aspect. But there is no denying the fact that wide-spread private tutoring has virtually paralyzed high school education, while putting heavy financial burdens on the household economy. And also there were fears that a sense of frustration was developing among poor families which were unable to gain access to costly private tutors. To slove these educational, economic, and social problems the「Special Committee for National Security Measures」announced a package of drastic measures, that is,「7.30 educational reform in 1981」designed to discourage overheated private tutoring and put the school education back to normal, including the abolition of individually-held college entrance examinations and the introduction of a「graduation system」. In this context the purpose of the present study aims to investigate linkage between educational policy reform and university administration. To identify the variables of school system the conceptual frame-work was tentatively built as input-transformation-output model. The principal methods used in this study are analy sing the related references and interivew. Prospecting the future of higher education in Wonkwang university, following educational administration directions were identified as follows: ① Effective and flexible management of a "graduation system". ② Operating rigid evaluation systems for academic achievement. ③ Improving the quality of faculties. ④ Improving the management of personnel and finance. ⑤ Developing public relation media.

토양에서 분리된 방선균들에 의한 Rimazol Brilliant Blue R(RBBR) 염료의 탈색에 질소원과 pH가 미치는 영향

김태전,김승곤,윤경하 서울保健大學 1997 論文集 Vol.17 No.1

Many workers had reported that the degradation of lignocellulose and lignin by white rot fungi were significantily correlative with the degradation of phenol or PAHs (Polycyclic aromatic hydorcarbons) compounds and the decolorization of a various dyes, specially RBBR (Remazol brilliant blue R) and Poly R-478 dyes. but it were not known distinctly that the degradation of these and the decolorization of these by Actinomycetes were related to the degradation of phenol or PAHs compounds, and author had examined in relationship between the degradation of lignocellulose or lignin and the decolorization of RBBR by Actinomycetes isolated in 67 soil samples collected at 8 areas of Korea from February, 1994 to March, 1995. In the experiment, There were selected two strains identified as Streptomyces halstedii scabies SA1-36 and Streptomyces lavendulas SA2-14 which had good correlation between the degradation of lignocellulose or lignin, and it were investigated that the cultural parameters to maximize the decolorization ratios of RBBR by two strains, as the results, Streptomyces halstedii scabies SA1-36 revealed each the highest decolorization ratios with 73.4% in 0.30% glycerin and Streptomyces lavendulas SA2-14, with 74.1% in 0.25% cellobiose at 30℃ in 20 days of culture. There were used their results as basal data in this study that examined the effects of nitrogen sources and pH to maximize the decolorization ratios of RBBR. It were summarized as following that the results examined the effects of nitrogen sources and pH to maximize the decolorization ratios of RBBR by two strains. 1) It were the highest each as 75.7% in casein and 75.7% in yeast extract that the dicolorization ratios of RBBR by Streptomyces halstedii scabies SA1-36 and Streptomyces lavendulas SA2-14 strains according to nitrogen sources(0.l%). 2) It were the highest each as 76.8% in 0.1% casein and 78.3% in yeast extract that the decolorization ratios of RBBR by Streptomyces halstedii scabies SA1-36 and Streptomyces lavendulas SA2-14 strains according to the concentrations of casein and yeast extract. 3) It were the highest each as 76.8% in pH 7.6 and 79.4% in pH 6.6 that the decolorization ratios of RBBR according to pH by Streptomyces halstedii scabies SA1-36 and Streptomyces lavendulas SA2-14 strains. In the above results, we could knowe that it were each different as well as carbon sources that nitrogen sources and pH required between Streptomyces halstedii scabies SAl-36 and Streptomyces lavendulas SA2- 14 strains. and organic nitrogens influence more than inorganic nitrogens to decolorize RBBR dye and nitrogen sources and pH influence lower than carbon sources to decolorize RBBR dye. What`s more, we could knowe that it were very important to use newly formuliged optimal basal media maximize decolorization ratios of RBBR dye by Streptomyces halstedii scabies SAl-36 and Streptomyces lavendulas SA2-14 strains.

화농성 심장막염은 전 세계적으로 매우 드물고 사망률이 높은 질환이다. 화농성 심장막염은 대부분 심장막을 침범하지만, 국소적으로 농양을 형성하는 경우도 보고 되고 있다. 세균에 의한 화농성 심장막염은 전체 급성 심장막염의 원인 중 6% 정도를 차지하고 있다. 그 중에서 혐기균에 의한 화농성 심장막염은 호기균에 의한 것보다 훨씬 드물다. 저자들은 만성 신질환으로 혈액 투석을 받고 있는 58세 남자에서 발생한 B. fragilis에 의한 화농성 심장막 농양과 심장눌림증을 국내에서 처음으로 경험하였기에 이를 고찰과 함께 보고하는 바이다. Purulent pericarditis is a rare, life-threatening condition and usually ivolves the whole pericardium. However only few cases have been reported in which a loculated pericardial abscess occurred from purulent pericarditis. The prevalence of acute pericarditis due to bacteria was 6%. Purulent pericarditis due to anaerobic bacteria has been reported less frequently than aerobic bacteria. There was no report about purulent pericarditis due to Bacteroides fragilis in Korea until now. So we report the first case of pericardial abscess due to B. fragilis in 59 year old Korean male with history of chronic renal failure and hemodialysis, that was complicated with pericardial tamponade.

The character of Cu(II) complex with ligands 5, 7, 7,12,14,14-hexamethyl-1,4,8,11-tetraazacyclotetradeca-4, 11-diene [L₁] and 5, 5, 7,12,12,14-hexamethyl-1,4,8,11-tetraazacyclotetradecane [L₂] was studied by means of spectroscopy. The _(max) of Cu(II) complex with ligand L₁ resolved in methanol was 730.8nm under pH 4-5 and 542.5nm under pH 8 or above. The Cu(II) complex with ligand Lz resolved in methanol showed the _(max) of 520nm under pH 4 and 5 and 540-542nm under pH 8 or above. Thus the equilibrium states in the acid solution is different from that in the alkaline solution. As the Mole ratio of Cu(II) with the ligand is 1: 1, the reaction steps of the complex could be estimated. The degree of absorbancy was decreased as the polarity of solvent decreased and it decreased in order of methanol, ethanol and buthanol. The degree of absorbancy of Cu(II)-L₁ and Cu(II)-L₂ complex under pH 10 was linear between the concentration of 1.0×10-³∼1O×10-² moI ι-³. It was confirmed that the Beer's Iaw works within this concentration and thus this can be applied to measure the quantity of Cu(II) in a limited concentration.

This study was conducted to detect the allelopathic effect of water and ethanol extracts from 4 plant species (Lactuca sativa L., Ambrosia elatior L., Oenothenra odorata Jasp., Ginkgo biloba L.) on germination and growth of lettuce seeds. A little bit higher inhibitory effect was obtained in ethanol extracts rather than water extracts. Allelopathic effects varied in the source of extracts and concentrations of 4 plant species and the highest allelopathic effect appeared in 10% solution, regardless of plant species.

1987년 6월과 8월 2회에 걸쳐 珍島內의 7개 調査地点에서 淡水魚類의 분포, 生態 및 形態등을 조사하였다. 총 採集個體數는 2,753個體로 同定 결과는 9科 24屬 30種으로 밝혀졌으며 Pseudorasbora parva, Hemiculter eigenmanni, Abottina rivularis, Aphyocypris chinensis, Acanthorhodeus gracilis, Misgurnus mizolepis 등 6種의 1次 淡水魚와 Trachydermus faciatus, Tridentiger obscurus, T. trigonocephalus, Acanthogobius elongata, A. hasta, A. lactipes, A. flavimanus, Acentrogobius pflaumi, Pseudogobius masago, Mugilogobius abei, Chaenogobius annularis, C. mororanus, Periophthalmus cantonensis, Fugu niphobles 등14종 2次 또는 周綠性 淡水魚가 珍島에서 처음으로 그 분포가 확인되었다. 본 지역에서 採集된 1차 담수어 중 Abottina rivularis, Acanthorhodeus gracilis는 지금까지 어느 島嶼地方에서도 分布가 확인된 적이 없는 種이며, Cobitis longicorpus, A. gracilis는 韓國特産種으로 그중에 C. longicorpus는 珍島가 육지로부터 분리되기 전에 分布되었던 種으로 그리고 A.gracilis는 2次的인 이동에 의해 분포된 種으로 생각된다. 쌍계천 상류지역인 st.1(쌍계천계곡)과 st.3(창포교 일대)에서는 섬의 상류ㅣ지역의 전형적인 특징종인 M.oxycephalus, O. latipes가 st.4(송정저수지)와 st.7(둔전저수지)에서는 혼탁한 수질상태에서 주로 서식하는 H.eigenmanni, P.parva, C.auratus, A.rivularis 등이, st.6(금갑리)와 st.7(벽파리)에서는 汽水域에서 주로 서식하는 망둥어科 어류들이 서식하고 있는 특징을 보였다. 우점종인 M.oxycephalus와 H.eigenmanni의 全長組成과 分布上 特異한 種인A.gracilis, A.rivularis, C.longicorpus의 生態와 측정치 등을 밝혔다. Distributional, morphological and ecological characters of the freshwater fishes were investigated at the seven stations in Jin-do on June and August, 1987. In this survey, 9 families, 24 enera and 30 species (totally 2753 individuals) were collected and indentified. Among them, Pseudorasbora parva, Hemiculter eigenmanni, Abottina rivularis, Aphyocypris chinensis, Acanthorodeus gracilis, Misgrurnus nizolepis were primary freshwater fishes, and Trachydermus fasciatus, Tridentiger obscurus, T. trigonocephalus, Acanthogobius elongata, A. hasta, A. lactipes, A. flavimanus, Acentrogobius pflaumi, Pseudogobius masago, Mugilogobius abei, Chaenogobius annularis, C. mororanus, Periphthalmus cantonensis, Fugu niphobles were pheripheral fishes. It was remarded in the view point of zoogeography of island freshwater fish of Korea that A. rivularis and A. gracilis were observed in the present studied areas for the first time. Two endemic species of C. longicorpus and A. gracilis were found in the present studied area and the former was belived to be the originally distributed species, however the latter might be considered secondary distributed species originated from elsewhere. The abundant species of this studied area were M. oxycephalus, O. latipes at st.1 and st.3, and H.eigenmanni, P. parva, C. auratus, A. rivularis at st. 4 and st. 7 and the gobiid fishes were at st.5 and st.6. The total length of M. oxycephalus and H. eigenmanni, the dominant species of present studied area, were measured and analyzed. Morphological and ecological characters of A. rivularis, A. gracilis and C. longicorpus which were the characteristic species of the distribution were compared with those species reported previously by others.
