Synthetic activated ceramic(SAC) adsorption isotherms were determined experimentally for the raw sewage and final effluent of JANGLIM sewage treatment plant. SAC media used in this study is the media made under high temperature, which has many pores on the surface. The well-known Freundlich equation developed for this work, was used to describe single solute equilibria. As expected, the Freundlich equation was able to more accurately describe single solute isotherms which deviated from log-log linearity. It showed that the adsorbed COD mass per adsorbent mass in the adsorption equilibrium was larger in raw sewage(1.40mg/g) than in effluent(0.28mg/g), when the adsorbent mass was 50g. SEM(Scanning Electron Micrograph) of SAC media indicated that a large of biomass were attached in the surface and pores of the SAC media, after 90 days of operation.

이종구,박원규 한국공작기계학회 2002 한국생산제조학회지 Vol.11 No.4

One characteristic of Fine-Blanking is that the size and the direction of stress and strain are very complex in the plastic flow according to the condition of blanking. Especially, they are affected by the clearance of punch and die, by the force of blanking holder and by the force of counter punch. The purpose of this research is to know the deformation behavior in shear zone more clearly, based on Green & Cauch's large deformation theory. The deformation behavior and cracks were investigated in each step of shear, according to punch penetration increase, the use V-indenter ring the hardness of materials. This research found that the transforming behavior was the same as pure discretion, and the cracks could be prevented when hardness is low.

This work is concerned with construction of the intelligence stress predictor for compression strength evaluation using neural network-ultrasonic waves. The contact pressure in jointed plates was measured by using ultrasonic technique. Neural network is used to evaluate and predict contact pressure from the results of the calibration curves. The organized neural system was learned with the accuracy of 99%, as a result of learning the ultrasonic echo ratio to the contact pressure measurement between SM45C and STS410 materials. And it could be evaluated and predicted with the accuracy of 90% in the evaluation of ultrasonic echo ratio difference in the same surface roughness and contact pressure, and 85% in the prediction of virtual ultrasonic echo ratio. Thus the proposed stress predictor is very useful for the evaluation and prediction of the contract pressure between SM45C and STS410 materials.

The purpose of this study was to investigate the problems and to make a solution for the management of subject teacher system (particularly, physical education, music education, and art education) in elementary school. The subjects were 980 elementary school teachers who were randomized by researchers. They reported their perceptions and opinions with a questionaire that was developed by researchers and some other teachers were interviewed on the problems and means of sattling that of the management of subject teacher system in elementary schools. The results of this study were as follows. 1. School Principals should be have a new understanding about the purpose of subject teacher system that could be devote to improve the quality of subject-matter education and the effectiveness of instruction. 2. Subject teacher system have to be applied in 4-6 grade in elementary school. 3. Preferentially, subject teacher system should be applied for physical education, music education, and art education. 4. The references of selection for subject teacher should be restricted within volunteers and effective teacher on the selected subjects. 5. The school hours of subject teacher should be limitted to under 22 hours per week, and in the case of physical education, music education, and art education teachers should be limitted to below 18 hours. It is necessary that educational facilities, materials, and rest space for subject teachers should be expanded. 7. To attract physical education, music education, and art education teachers, new incentive system should be adopted. 8. To improve human relationship between subject teachers and class teachers, cooperative program should be developed. 9. It is necessary for subject teachers that the opportunity involved solf-improvement and self-realization should be offered. 10. In the last analysis, physical education teacher, music education teacher, 문 art education teacher should be educated in the major courses at the teachers college.

저자들은 만성알콜중독의 원인으로 음주자의 성격, 사회요인 등 여러가지 문제들이 게재되어 있지만 유전적 요인도 중요하리라고 생각되어 만성알콜중독자로 진단되어 국립부곡정신병원에 입원가료 중인 환자 30명을 대상으로 ADH2의 다형현상(polymorphism)을 조사하여 알콜중독자가 아닌 건강한 한국인의 유전자형과 비교한 결과 다음과 같은 결과를 얻었다. 만성알콜중독자 30명 중 ADH2-1/ADH2-1 형을 갖는 사람이 27명이었으며 ADH2-1/ADH2-2를 갖는 사람이 3명이었다. ADH2¹의 gene frequencies는 0.68이었으며 ADH²의 gene frequencies는 0.32로서 정상 한국인과 비교하여 유의한 차이가 없었다. This study was performed to know the gene polymorphism of alcoholic dehydrogenase(ADH)-2 in 30 Korean alcohol addicted patients who were admitted at Bugok National Mental Hospital. The results were as follows ADH-2/ADH2-1 type among 30 alcohol addicts were 27 and ADH2-1/ADH2-2 type were 3. Gene frequencies of ADH2-1 were 0.68 and gene frequencies of ADH2-2 were 0.32 These results were not different from the gene polymorphism of ADH2 in non-alcoholic Korean healthy adults.

Purpose : To evaluate the clinical results of modified tension band wire technique using cortical screw for treatment of displaced medial malleolar fractures of the ankle. Materials and Methods : From January 2001 to January 2003, 24 patients were treated by modified tension band wiring using cortical screw for medial malleolar fracture. The follow-up period was 12~35 months (average 18 months). There were 13 males and 11 females, and the mean age was 46 years. Fractures were classified by Lauge-Hansen's classification. The results were analyzed by Meyer and Kumler's criteria. Results : There were 13 cases (54%) of excellent, 9 cases (38%) of good, and one case of fair because of limitation of motion of the ankle joint and one case of poor which showed post-traumatic arthritis of the ankle. Conclusion : Modified tension band wire technique using cortical screw can be an effective operative method for the treatment of displaced medial malleolar fractures of the ankle.

The Actinomyces species are normal flora of oral cavity and upper intestine characterized as gram-positive, non-spore-forming anaerobic or mjcroaerophilic rods. Actinomycosis is a chronic suppurative and granulomatous disease characterized by abscess, sinus, abundant granulation and mass. The appendix is the commonly involved site among abdominal actinomycosis. Abdominal actinomycosis is often difficult to diagnose before operation because of no reliable clinical features and infrequency of the disease. We report two cases of abdominal actinomycosis which were manifested as acute appendicitis. Those were detected Incidentally tv the pathologist after routine appendectomy. Both patients were successfully treated with appendectomy followed by proper antibiotics use.
