한강 중하류의 남조류 및 환경요인의 연간변화 (2000 ${\sim}$ 2003)를 파악하기 위하여, 2000년 4월부터 2003년 10월까지 4년간 성수대교에서 성산대교까지 총 5개 지점을 선정하여, 수계의 기초환경요인 및 식물플랑크톤 현존량 변화를 조사하였다. 조사기간 동안, 남조류의 현존량은 점차적으로 감소하여 장기간 강우가 가장 많았던 2003년에는 거의 관찰되지 않았으며, 총 식물플랑크톤 현존량에 대한 남조류의 기여도는 약 10%범위내였다. 이러한 현상은 매년 강우집중기 동안 팔당댐으로부터 많은 방류수가 유입됨으로서 수온감소는 물론 광량감소, 영양염류 희석 등에 의한 남조류의 성장이 제한된 것으로판단되며, 동일시기에 다른 조류 (녹조, 규조 등)의 높은 성장으로 엽록소 a와 식물플랑크톤 현존량이 뚜렷하게 증가하였다. 따라서 한강 하류의 고온기 동안 남조류 성장은 잦은 강우와 방류에 의해 제한을 받지만 규조나 녹조와 같은 다른 조류들의 높은 성장으로 대치되는 천이현상을 보였으며, 기후영향을 크게 받는 전형적인 하천생태계의 특성을 나타냈다. For 4 years (2000 ${\sim}$ 2003), annual fluctuations of standing crops of cyanobacteria and physicochemical factors were examined at five sites from Bridge of Seungsoo to Bridge of Seungsan in the lower part of Han River. The cyanobacterial abundance (ND to 4,167 cells $mL^{-1}$) was strongly decreased during the heavy rains in every year. During the similar periods in 2003, cyanobacteria hardly observed, and comprised below of 10 percentage of total phytoplankton. In the period of little cyanobacteria, some green algae and diatom dominated the phytoplankton community, while the concentration of chlorophyll a has not largely change. These results indicate that heavy frequent precipitation strongly limited the growth of cyanobacteria, and lead an algal succession by the appearance of new algal groups.

肝吸蟲에 대한 Albendazole의 殺蟲效果에 관한 實驗的 硏究

裵平元,金洙鎭,林漢鍾 고려대학교 의과대학 1984 고려대 의대 잡지 Vol.21 No.3

Newly developed albendazole(zentel®) is a broad spectrum anthelmintic which high activity against intestinal nematodas as well as trematodes and cesstodes infections. The present study was undertaken to evaluato in vitro and in vivo activities of albendazoles against adult worms of clonorchis sinensis. The morphological change of C. sinensis obtained from experimentally infected rats treated with various dosages of albendazole were studied by means of scaning and transmission electron microscope. The results are as follows: 1. The adult worms of C. sinensis were incubated in the medium containing albendazole with various concentrations. By 24 hours after incubation, none of the worms were dead in concentrations of 0.01μg/ml of albendazole. 2. In order to evaluate the effect of albendazole in vivo, experimentally infected rats with 50 metacencariae of C. sinensis each were treated orally with various dosages of albendazole. In the result, anthelmintic effect was confirmed at the dosage of albendazole with 2×25㎎/㎏×2 days (total amounts 100㎎/㎏). 3. Macrocopital examination was to the clonorchis worms which were collected from the bile ducts of the rats autopsied at 24 hours after treatment with albendazole. The lack of intestinal contents was observed in most of worms from the groups treated with 1×200 ㎎/㎏ and 2×25 ㎎/㎏×2 or 4 days, and the elongation of the anterior portion of the worm body was also observed n the worms from the groups treated with 2×25 ㎎/㎏×2 or 4 days. 4. In the scanning electron microscopic observation, many blebs were fromed on the surface of the damaged tegument of the worms at 24 huors after treatment with albendazole(1×200 ㎎/㎏ and 2×25 ㎎/㎏×2 or days). 5. The transmissions electron microscopic observation indicated that degeneration of mitochonriae and destruction of tegumental syncytium of the worms at 24 hours after treatment with albendazole(1×200 ㎎/㎏ and 2×25㎎/㎏ or 4 days). Inaddition to the findings the degeneration of the intestinal lamellae in the caeca was also observed in the worms from the groups treated with same dosages of albendazole.

Method: consulted 304 disabled children who visited rehabilitation center of disabled children in Seogu health center in Taegon city during the period of October 1994 through December 1988. The data were analysed for the diagnosis and birth characteristic. Results: Type of disabled children were emotional disabled children in 25.3%, cerebral palsy in 23.4%, speech disabled children in 15.5%. Frequencies of type of the cerebral palsy were spastic type in 23.4%, mixed type in 11.3%, athetoid type in 4.2%. Boys(69.4%) were twice girls(30.6%). Age distribution when parents visited center were past. Academic background of parents were high. Distribution of birth weight studied were : 3.001∼3.500gm 38.7%, 2.50∼3.00gm 24.8%. Status of birth were easy delivery in 52.0%, caesaren section 26.6%. disease of birth were seizure 26.7%, Conclusion: We wish early diagnosis and early treatment according to increasing academic background of parents. We have to note that emotional children and mixed type of cerebral palsy were increased due to improvement of medical skill and variation of social structure. Physical therapists must recognize that the type of disabled children and characteristic is changed according to age.

치은연하 파절로 치조골 소실을 동반한 상악측절치에서 orthodontic extrusive remodeling후 임플란트 식립을 통한 심미수복 : 증례보고

황수연,손원준,한영철,배광식,백승호,이우철,금기연 大韓齒科保存學會 2008 Restorative Dentistry & Endodontics Vol.33 No.1

심미적으로 중요한 전치부에서 단일 치아 임플란트를 이용한 보철수복은 임상의에게 새로운 도전과제 중의 하나가 되었다. 그러나 전치부에서 single-unit implant는 식립할 부위의 치조골 상태가 양호해야 하는데 치은연하 파절로 인해 치아 주위에 골 손실이 있는 경우 immediate implant는 심미적으로 문제를 야기할 수 있다. 따라서 본 증례는 "orthodontic extrusive remodeling"을 통해 파절치와 주위 조직을 교정적으로 정출시켜 임플란트 식립을 위한 연조직과 경조직을 증대시킨 후 임플란트 식립을 통해 상악측절치에서 성공적인 심미수복을 이룬 증례에 관한 것이다. The treatment of esthetic areas with single-tooth implants represents a new challenge for the clinician. In 1993, a modification of the forced eruption technique, called "orthodontic extrusive remodelling" was proposed as a way to augment both soft- and hard-tissue profiles at potential implant sites. This case report describes augmentation of the coronal soft and hard tissues around a fractured maxillary lateral incisor associated with alveolar bone loss, which was achieved by forced orthodontic extrusion before implant placement. Through these procedures we could reconstruct esthetics and function in a hopeless tooth diagnosed with subgingival root fracture by trauma.

This paper presents a method of decentralized optimal control for time invariant large scale systems via Single Term Walsh Series. In coordinator of decentralized optimal control, the interaction prediction principle approach of Takahara is used as the vehicle for large scale system. The main reason for this is that the prediction method require very little second-level calculation. In the subsystems of that, it is well known that the optimal control of a large scale system with quadratic performance criteria often involves the determination of time varying feedback gain matrix by solving the matrix Riccati differential equation, which is usually quite difficult. Therefore, in order to solve the problem, this paper is introduced to Single Term Walsh Series. The advantages of proposed method are simple and attractive for the control of large scale system in computation.
