백색부후균 Phanerochaete chrysosporium의 고정화에 관한 연구
金保局,元燦喜 全北大學校 附設 都市및環境硏究所 1996 都市 및 環境硏究 Vol.11 No.1
One of the important things for biological wastewater treatment is to maintain microorganism to high concentration purely. For this, a white rot fungus, Phanerochaete chrysosporium is immobilized because it is known that lignin, nondegradable substances of the papermill wastewater, can be degraded soundly. The purpose of this study is to find an appropriate mixing ratio of immobilized Phanerochaete chrysosporium and filling ratio when a reactor is operated. The results of this study are follows; 1) The ratios of mixture between 2:1, 1:1, 1:2 white rot fungi Phanerochaete chrysosporium with PVA had a little effect on respiration rates. The amount of suspended solid produced from 2:1 ratio was negligible and the stability of the mixture was also good at 2:1. 2) The maximum removal efficiency was obtained when the filling rate was 25%.

This study was conducted in order to investigate removal efficiency of turbidity, organic matter, nitrogen and phosphorus to reduce environmental pollution of treatment livestock wastewater with mixed proportion of loess and lime. The result of study, the removal of turbidity, COD_Cr and T-P increased along the dosage, and was to be fixed above the appropriate dosage. In the removal turbidity, the appropriate mixed proportion of loess and lime was Loess:Lime = 3:7, the appropriate dosage was 30g. In the removal COD_Cr, T-P and TKN was Loess:Lime = 3:7, 30g, Loess:Lime = 5:5, 20g, Loess:Lime = 5:5, 40g, respectively.

측방확대장치에 의한 정중구개봉합부의 확대시 고정력은 구개부의 신경요소들에 변화를 일으키면서 동통을 유발하게 되고 구개봉합부가 확대되고 그것이 유지되는 동안에 기계적 자극에 의한 구개부신경섬유의 반응성에 변화를 일으킬 것으로 생각된다. 본 연구에서는 백서 정중구개봉합부의 CGRP 면역반응 신경섬유의 교정력 적용시간에 따른 형태학적인 반응성, 밀도, 분포변화등을 관찰하고 그와 연관된 CGRP의 기능을 알아보고 자 250gm내외의 Sprague-Dawley 웅성백서 상악전치에 200gm의 치아이개력이 가해지도록 활성화시킨 helical spring을 삽입하여 정상대조군과 장치 장착후 경과시간에 따라 1일, 4일, 7일, 14일 경과군으로 나누어 정중구개봉합부를 확대후 희생시켜 면역조직화학법으로 염색하여 관찰하였다. · 대조군에서 정중구개 봉합붑 결합조직의 CGRP 면역양성 신경섬유는 거의 관찰되지 않았다. · 1일군에서는 대조군에 비해 CGRP 면역반응 신경섬유가 현저한 증가를 보였으며 주로 혈관 주위에 염주알 모양의 가는 신경섬유가 관찰되었다. · 4일군에서는 CGRP 면역반응 신경섬유가 대조군에 비해서는 현저한 증가를 보였으나 1일군에 비해서는 크게 증가하지 않았으며 혈관의 크기가 훨씬 확장되어 관찰되었다. · 7일군에서는 특징적으로 조골양세포가 새로이 형성된 골변연을 따라 줄지어 배열되는 독특한 양상이 관찰되었고 신경섬유의 수는 4일군에 비하여 감소하고 혈관의 직경도 감소되었다. · 14일군에서는 CGRP 면역반응 신경섬유가 7일군과 유사한 분포를 보였으며 확대에 의한 골변연의 불규칙성도 대체로 감소되었다. CGRP 면역반응 신경섬유는 정중구개봉합의 확대시 초기에 일어나는 신경원성 염증반응에 주로 관련되어 증식되는 것으로 생각된다. Midplatal suture expansion is often used for patients having narrow maxillary arch, cleft palate, respiratory handicap with narrow nasal cavity. CGRP has been known as a modulator of pain transmission in central nervous system and a local effector to peripheral tissue causing vasodilation, increase of blood flow, modulation of immune system, regulation of macrophagic function and stimulation of bone formation. To investigate changes of CGRP-immunoreactive nerve fibers in midpalatal suture during the the expansion, immunohistochemical study was performed by using rats. Experimental rats(10weeks, 250gm) were divided into five groups(control, 1, 4, 7, 14 days group (each n=4) and applied orthodontic force (approximately 200gm) to upper anterior incisors. Frozen sections of midpalatal suture area were immunostained by using rabbit antisera. The results were as follows. · The CGRP-immunoreactive nerve fibers were hardly observed in control group. · In 1 day group, the CGRP-immunoreactive nerve fibers were more increased around the vessels than control group. · In 4 days group, the CGRP-immunoreactive nerve fibers were more increased than control group, but not more increased than 1 day group. Vascular diameter was more enlarged. · In 7 days group, expecially, hematoxilin affinity of cells was remarkable and cells were arranged along the bone margin. The CGRP-immunoreactive nerve fibers were more reduced than 4 days group and vascular diameter was also reduced. · In 14 dayds group, the CGRP-immunoreactive nerve fibers were similar to those of 7 days group and the irregularity of bone margin was almost recoverd. In Conclusion, the CGRP-immunoreactive nerve fibers may be related to initial neurogenic inflammatory reaction in expanding mid-palatal suture.

The discharge of papermill wastewater has been continuously increased from 512,000 ㎥/day in 1987 to 735,000 ㎥/day in 1994. The method used for treating this type of industrial wastewater has been an activated sludge process, which may be the most effective and widely used form of biological wastewater treatment, but this method causes some operational problems when it is applied for treating a papermill wastewater: i. e.) 1) activated sludge processes are efficient for reducing BOD removal but are not effective in reducing COD level due to a higher fraction of NBDCOD caused mainly by celluloses and lignins, 2) the extra sludge production is too much. It is known that lignins can be soundly degraded by Phanerochaete chrysosporium called "a white rot fungi". Treating papermill wastewater using an immobilized Phanerochaete chrysosporium would give some relative benefits: 1) it can reduce a significant fraction of NBDCOD of the papermill wastewater, 2) the sludge production can be reduced. The results of this study can be used to provide not only new and innovative design parameters for prototype treatment process but also to renovate the existing treatment facilities. The results of this study are follows; 1) Nutrient(P) injection had no significant effect on the removal efficiency. 2) The operational condition that could keep the national discharge limit of effluent("Na" zone, less than COD_Mn 90㎎/ℓ and less than BOD_5 80㎎/ℓ) was about 0.33㎏-BOD_5/㎥·day or less, and was required for the same limit more than 8 hours of hydraulic time. 3) The sludge produced from treating one cubic meter of papermill wastewater was about 0.001 ∼ 0.06 ㎏/㎥, which is much less than the amount of activated sludge produced.

This study was carried out to recognize the distinctive quality of the scene around 'PUNGAMGEONG'(楓巖亭) through appreciation in its building, location and architectural view of the space based on 'KIM CHUNG JANGGONGYUSA'(金忠壯公遺事), published during the reign of 'JEONGCHO'(正祖) in 'CHOSON'(朝鮮) dynasty. The study was conducted by contents analysis of 'KIMCHUNGJANGGONGYUSA' and other related paleography as prime as well as verification of the location and architectural view of the space through field survey with topographical chart(1/5,000, 1/25,000) and survey drawing. Analysis method fell into the background of building and location space structure as well as a comparative analysis of the literature with interview with local authority staffs and descendants. The results are as followings; 1) The background of the Pungamjeong's building is influenced by KIMDEOKBO(金德普)'s amusement(good landscape gusto) in fine view and moralistic view in nature as well as seclusion and recuperation with misfortune of his family. 2) Location of the Pungamjeong is suitable for seclusion with graceful natural scenes as well as adjacency with the ancestral burial ground for memorial service. 3) The space structure of the Pungamjeong for literature analysis consists of the space for production in bamboo grove to stream surrounding, the space for study and appreciation in pavilion and the space of fairyland in left side of locks. 4) The Pungamjeong stands with a pavilion of two rooms reconstructed in the tile house, and the vegetation appears in the literature of Pinus dansiflora S. et Z, Prunus mume S. et Z, Phyllostachys nigra Munro, Acer pseudosieboldianum Komar and Prunus persica (L.) Batsch forming identifying marks, but Pinus densiflora S. et Z, Phyllostachys nigra Munro, Abies holophylla Maxim, Acer pseudosieboldianum Komar, Carpinus laxiflora Blume, Zelkova serrata Makino, Prunus sargentii Rehder, Fraxinus rhynchophylla Hance, Quercus monglica Fisch and Rhododendron mucronulatu Turcz are found recently. Also, wild natural rocks in the Pungamjeong are one of its valuable parts representing personality of folk belief to the local residents. It is recommended that further embodied and substantive studies should be followed with the systematic literature analysis and field survey for restoration and maintenance of the place since this study comes from the literature analysis only.
