The purpose of this study is to find ways for the improvement of science instruction by describing and analyzing the schooling process in the class-room of the middle school through the participant observation. Four differ-ent middle schools and four different science teachers were selected. And intensive participant observations were made about total 18 hours' school-ing process concerned to the instruction of ' Photosynthesis' and 'Digestion' which are two units in the science textbook of the middle school. The documentary records of the results of field research on schooling the classroom were made. On the basis of these data analytical diagrams of each hour's schooling process were made and each teacher's teaching type, instrucion process type and teaching method about the same teaching contents were comparatively analyzed. Through this analysis, the following conclusions could be obtained. 1. Teaching type was divided largely into two different kinds, such as laboratory lessons in the laboratory and lecture lessons in the classroom. Laboratory lessons were conspicuously grouping lessons, and the lessons in the classroom were lecture lessons practiced by the lead of the teacher. 2. Instrucion process model stood out as an 'Inquiring Model' in the the-oritical model in case of laboratory grouping lessons, that is, in which 'inquiry learning process' was dominant, and stood out as 'Concept Model' explained by the teacher or 'Discovery Model' by suggesting teaching materials in case of lecture lessons. 3. Teaching method, even in case of the same teaching contents, showed various styles according to the different teachers. such as structur-izing lesson, providing instructional cues, questioning and reacting to stu-dents 'response, explanation and writing on the blackboard, student con-trol in class. But in case of the' same teacher the same styles were found in suggesting teaching aims, teaching arrangements, turning over in teach-ing. explanation and writing on the blackboard, of every class hour. 4. In order to make a qualitative improvement for the science instruc-tion, the inquiring instruction process, that is the greatest aim of science education, should necessarily be practiced in each class, and through this teaching process the present limits of science instruction should be over come. Therefore, the exploring attitude of each teachers own to renew the instruction stratege, Comparing the existing instruction process model, and teaching methods of individual teacher's, is thought to be nessessary. For this, through the teacher's training program or the teacher's retrain-ing course, the various ways to improve the science instruction quality should be provided by using ethnographic data on schooling as a tool for the indirect experience about other's schooling process.

A study on the wintering birds on Cheju Island was conducted from October 1993 to February 1998. The total number of birds observed in this survey was 37,302 of 73 species, -23,066 birds of 66 species at Hado-ri fishfarm and 14,236 birds of 48 species at sungsan-po fishfarm. The most dorminant species was Anas penelope 26.59%(9,920 individuals), followed by Anas strepera 21.36%(7,996 individuals), and then Anas poecilorhyncha 19.56%(7,287 individuals). The number of species and individuals of wintering birds in each year were recorded: 5.068 birds of 32 species in 1993, 5,068 birds of 36 species in 1994, 8,349 birds of 34 species in 1995, 9,013 birds of 44 species, 9,236 birds of 49 species in 1997. The number of species and individuals of birds became increasingly at Hado-ri fishfarm, but decreasingly at Sungsan-po fishfarm. Species diversity was founded within the range of 0.639∼1.796, and among two areas quotient of similarity was 0.702. The rare birds of 11 species were recorded in this survey.

The present study was performed to investigate the periodontal response following orthodontic intrusion of teeth with vertical bony defect produced by periodontal disease. Vertical bony defect and periodontal disease were produced adjacent to the both maxillary second lateral incisors in four adult dogs, weighing 20kg or more. Four weeks later, a flap operation was performed to eliminate inflammation and a reference notch was made on the root surface at the level of bottom of each defect. Two weeks after periodontal surgery, four weeks of intrusion and another four weeks of retention was executed on the right incisors while left incisors served as the control. Through the histologic analysis, following results were obtained. 1. The periodontal lesion which was produced by elastics and artificial bony defect was characterized by three walled infrabony pocket. 2. In the histologic section of control side, the base of the pocket was located below the level of the cemento-enamel junction. Connective tissue attachment was formed apically from the base of the pocket. 3. On the experimental side, the base of the pocket was localized close to the cemento-enamel junction. Connective tissue attachment was formed near to pocket base and extended apically. 4. New cementum was formed from the notch coronally toward the epithelial junction along the root surface in the both intruded incisors and control. 5. In the fluorescence microscopic observation, bone regeneration was began at the base of defect and the remodelling pattern characterized by a combination of coronal bone generation and resorption of the marginal crest could be detected. Although the remodelling pattern was the same in the both side, the bone remodelling in intruded incisors was continued during tooth movement. The results of the present study suggest that an orthodontic intrusion of extruded incisors with vertical bony defect can be carried out with a desirable periodontal response, provided that both the oral hygiene and the biomechanical force system are kept under control.

Five adults (3 cases of bilateral posterior crossbite, 2 cases of unilateral posterior crossbite) with intermaxillary discrepancy of over 5㎜ due to maxillary transverse deficiency were treated by surgically assisted rapid maxillary expansion (SARME). Bilateral maxillary horizontal osteotomies, osteotomies of pterygomaxillary junction and anterior lateral nasal wall, ans anterior palatal osteotomy were performed in 4 cases, and unilateral osteotomies in 1case, followed by palatal expansion with tooth-borne orthopedic applicance. No significant complication was observed. The mean palatal expansion was 7.2㎜ (5.8∼10.0㎜) in the maxillary first molar region. During the mean follow-up period of 4 years (5 months∼8 years 7 months), no recurrence of crossbite was observed in all cases. The SARME seemed to be a simple, stable, and reliable procedure for achieving a permanent increase of over 5㎜ in skeletal maxillary transverse width of adults.

This study was part of a continuous research project on the status of migrating shorebirds on major wetlands in Cheju Island. This study was conducted twice every month for two years, from March 1998 to February 2000. The investigated location are mainly two areas. The first census areas were Hado-ri fishfarm and the coast of Jongdal-ri in Kujaw-up and Sungsan-po fishfarm in Sungsan-up, all located in the eastern part of Cheju Island. The second census areas were Yongsu-ri reservoir and the coast of Kumdung-ri in Hangyoung-myon and the coast of Ilgwa-ri in Dejong-up, all located in the western part of Cheju Island. In total, 45 species consisting 5,117 individuals were observed during the census period. There were 40 species and 4,910 individuals in the eastern area, 38 species and 927 individuals in the western area. The number of individuals of shorebirds in the spring migratory season was greater than in the autumn. The dominant species researched during the first census period were 2,024 individuals of Calidrius alpina (88.5%), 84 individuals of Charadrius alexandrinus (3.7%), 59 individuals of Charadrius placidus (2.6%) in spring and 384 individuals of Calidrius alpina (82.9%), 20 individuals of Charadrius alexandrinus (4.3%), 11 individuals of Charadrius placidus (2.4%) in autumn.

An investigation into a bird community on grassland in Cheju Island was performed in 4 location : north, south, east and west which are selected as ecotone within a radius of 2km of Mt. Halla. The survey was done twice a month from July 1988 to June 1989 at 4 areas. 1. The total number and species birds observed during survey period were 2,758 and 55 respectively. And the dominant species were Hypsipetes amauroatis Parus major, Passer montarus in order. 2. 7 species were observed continuously during the all period of the survey, 22 species were observed for only a month. There was no species which was observed during the 4 month and 11 month periods of investigation 3. The regression line between the number of individuals and species showed 5% significance and its the correlativity was very high. 4. From the result of log. + ax. = b equation of MOTOMURA, the community structure of January was most simple and the order month was complex. 5. The diversity was high throught the three months of July, March, June and was low in August and January.

골결손과 치주질환 유도 후 성견 절치의 실험적 함입이동시 치주조직의 반응

황현식,박양수,최홍란 대한치과교정학회 1998 대한치과교정학회지 Vol.28 No.3

치주질환에 이환된 성인환자에서 상악전치의 치간공간과 아울러 정출이 발생된 경우 기능 및 심미의 회복을 위해서는 함입이동이 필요하다. 본 연구는 골하치주낭 즉, 수직적 골결손이 있는 절치의 함입이동시 치주조직 반응을 살펴보기 위하여 시행되었다. 상악 좌우 측절치에 골결손과 함께 치주질환을 유발시킨 성견 4마리를 실험대상으로 하여 양측 모두에 치주수술을 시행하고 결손부 최하방 치근면에 notch를 형성한 2주후 우측 제2측절치는 4주간 함입이동 후 4주간 보정을 시행한 실험측으로, 좌측 제2측절치는 구강위생관리만 시행한 대조측으로 사용한 바 조직소견을 통하여 다음과 같은 결론을 얻었다. 1. 함입이동없이 치주수술만 시행한 대조측의 조직소견은 치주낭 깊이의 감소를 보였으나 notch 부위부터 치주낭 기저부까지 긴 접합상피 상태를 보였으며 신생백악질이 형성된 일부에서만 결합조직 부착의 양상이 보였다. 2. 함입이동을 시행한 실험측은 대조측에 비하여 상피부착이 줄어든 반면 보다 넓은 신생 결합조직 부착 소견을 나타내었다. 3. 대조측과는 달리 실험측 notch 근처의 결합조직내에는 다수의 세포가 관찰되었으며, 신생 백악질 생성 역시 대조측 보다 많이 관찰되었다. 이상의 결과는 치주질환으로 인하여 정출된 치아에서도 철저한 염증조절과 구강위생이 유지되고 적절한 크기의 힘에 의하여 순수한 함입이동이 적용된다면 바람직한 치료결과가 가능함을 시사하였다. While periodontal disease results in the extrusion of upper incisors with interdental spacing in adult patient, the intrusive movement should be executed for the rehabilitation in terms of esthetics and function. The present study was performed to investigate the periodontal response following orthodontic intrusion of teeth with infrabony pocket. Bone defect and periodontal disease were produced adjacent to the both maxillary second lateral incisors in four adult dogs. Four weeks later, a flap operation was performed to eliminate inflammation and a reference notch was made on the root surface at the level of bottom of each defect. Two weeks after periodontal surgery, 4 weeks of intrusion and subsequent another 4 weeks of retention was executed on the right side of incisors while left incisors served as the control. Through the histologic analysis, following results were obtained. 1. Histologic section of control side showed the reduction of pocket depth after flap operation. However, the status of long junctional epithelium was observed while new connective tissue attachment occurred in a small area adjacent newly formed cementum. 2. Epithelial attachment was less around the intruded incisor while new connective tissue attachment was much more compared to the control side. 3. Plenty of cells were observed in the connective tissue around the reference notch of the intruded incisor and the degree of the new cementum formation was higher in the intruded incisor than the control. The results of the present study suggested that an orthodontic intrusion of periodontally involved and extruded incisors could be carried out with a desirable periodontal response, provided that inflammation is under control.

This study was part of a continuous research project on the status of waterbirds on major wetlands on Cheju Island. This study was researched twice each month for two years, from March 1997 to February 1999. In total, 29 species consisting of 4,887 individual birds were observed. The number of individuals of shorebirds was greater in the spring migratory season than in the autumn - in 1997, 131 birds in the spring, 104 birds in the autumn and in 1998, 2,453 birds in the spring, 635 birds in the autumn Pheasant-tailed Jacana, Eurasian Oystercatcher, Pintail Snipe and Temminck's Stint observed at the Hado-ri or Sungsan-po fishfarm are the first recordes on Cheju Island, Korea. Rare and endangered species were observed such as Eurasian Oystercatcher, Long-billed Plover, Far Eastern Curlew, and Spoon-billed Sandpiper. This survey area used for a suitable roosting and feeding place by many shorebirds. Thus, there is a need of critical plans for the conservation and management of shorebirds migrating in this area.
