This study has been carried out to evaluate the ability of sequential batch reactor process for the removal of organic substrate in wastewater. The results of this study are summerized as following: 1. The substrate removal efficiencies as the filling period were 30∼80% for both mode A and B, and the total removal efficiencies were around 90% for both mode A and B. 2. The substrate removal rates of filling periods were 0.42-0.90㎎/1/day and 0.11-0.45㎎/1/day for mode A and B respectively. For mode A the removal rates at the reaction periods were 0.764-0.865day^(-1). For operation mode B, it was found that the maximum removal rate was occurred when the experimental ratio of filling to reaction was 2/4. 3. Because the wastewater was at anoxic condition, the concentration gradient occurred with respect to time in batch reactor. So the sludge bulking due to excess growth of filamentous organisms was not observed.

The purpose of this study is to assess the postoperative stability and the tendency of relapse after both sagittal split ramus osteotomy in skeletal class III with anterior open bite. This retrospective study was based on the examination of 15 patients, 6 males and 9 females, with a mean age 23.1 years. The patients were divided into two groups based on the amount of preoperative overbite(group I:<1mm, group II:≥1mm). Serial lateral cephalometric radiographs were taken within 2 weeks preoperatively, within 1 week postoperatively and at a follow up period that ranged from 7 to 24 months postoperatively. All cephalometric radiographs were traced and digitized using the Quick ceph image Pro for analysis. And then, horizontal and vertical changes of reference points(B point, Pogonion, L1) were assessed by the linear measurements in millimeters on both axes. The results were as follows : 1 Mean horizontal relapses were 0.67±0.93mm (11%) at B point (P<.05) and 0.81±1.01mm (13.2 %) at Pogonion (P<.01). 2, Mean vertical relapses were 0.63±1.62mm (33.3%) at B point and 0.53±1.95mm (31.4%) at Pogonion (P>.05) 3. The mean angular change of occlusal plane to SN was 0.24±1.19 (P>.05) and that of mandibular plane to SN was 1.03±1.85 (P<.05). 4. There was correlation between the extent of preoperative overbite and the postsurgical relapse at B point and Pogonion. 5. There was no correlation between the amount of surgically produced horizontal movement and the postoperative horizontal relapse at B point.

A variety of materials and procedures such as sinus floor elevation, sinus-lift graft, inlay bone graft using Le Fort I osteotomy, and onlay graft have been used to create adequate bone volume in the maxillary sinus for placement of endosseous implants in the posterior atrophic maxilla. Because of the frequent lack of bone in the posterior maxilla, sinus lift procedure has become a commonly practiced treatment modality. The 138 endosseous implants of 36 patients with sinus augmentation procedures performed in Korea University Hospital from January 1991 to December 1998 were summarized and analysed. The result of this study were as follows : 1. Age ranged from 39 to 57, with a mean of 50.7. 2. The mean survival rate for 138 implants with maxillary sinus lift procedure was 80.4%. 3. There was no corelationship between the fixture length, width and the survival rate. 4. The result showed that the healing period for 8-12 months was necessary if the residual alveolar bone height was less than 5mm. 5. Autogenous iliac corticocancellous block graft showed the most favorable survival rate(95%).

초등학교 자연과 교육과정안의 작성과 그 연구

임정환,김병업,김명환,김재경 대구교육대학교 1970 論文集 Vol.6 No.-

This researching group of four members of us organized this test plan on the ground of following standpoints: 1. Science education should be designed for the general outline of natural science to be taught till the period of compulsory education is expired. 2. Natural science consists of two elements; one is the scientific method as a way of understanding nature and the other is the system of concept which is got as the result. 3. Science education should be designed, after increasing the belief in sciecne, for the effects of learning to be transformed into the sources of the judgements and behaviours. In this test plan, we definitely represented the above three standpoints as followings: 1. These system of concept of natural science can be condensed into several basic general concepts. These basic concepts become the essence of curriculum plan. Field of Non-living Matters Field of Living Thing 1. Matter 1. Feed 2. Force and Motion 2. Growth 3. Energy 3. Reproduction 4. Time and Space 4. Interaction to Environments 2. The general conepts are incessantly extended and deepened through the process while the scientific methods are applied. The scientific methods which are applied here are these: 1) Observation 2) Classification 3) Experiment 4) Modeling 3. The contents of the thextbook were chosen all over the fields of the natural science but the various contents should be taught wholly and connectively all over the nature. We settled the syllabus between the first grade and the sixth of elementary school on the ground of the above-mentioned basic standpoints and principles.(Refer attached table.) When this test plan is organized successfully, a desirable character who can flexibly adapt to the rapidly changing society and has extentive possibilities will be expected through science education.
