중심교합위 상태에서 편측이나 양측으로 구치부의 상악치아가 하악치아의 협측으로 위치한 경우를 scissors bite라고 한다. 이런 부정교합은 상악의 폭이 크거나 하악의 폭이 좁은 경우 발생한다. 이로 인해 턱의 성장이 방해를 받고 악궁간 부조화를 유발하며 적절한 저작을 할 수 없게 된다. 따라서 scissor bite는 즉시 차단 교정을 해야 하며 일반적으로 scissors bite의 치료는 고정성 또는 가철성 장치를 이용하여 하악을 확장한다. 이에 저자는 scissors bite를 보이는 환아의 4세의 두명의 남아에게 Schwarz 장치를 이용하여 양호한 결과를 얻어 scissors bite의 치료법 제시에 도움이 되고자 보고하는 바이다. A scissors bite in the posterior teeth occurs when the upper teeth are positioned totally or unilaterally buccal to the lower teeth in centric occlusion. This malocclusion can result from either excessive width of maxilla, deficient width mandible, or combination of both. The malocclusion can lead to hindered growth of jaws or to asymmetry between the jaws. Besides, the severe lingual inclination of the mandibular posterior teeth prevents adequate mastication. Thus, the scissors bite is in need of immediate interceptive orthodontic interbention. The common treatments of the scissors bite is to expand the mandibular arch: fixed or removable appliances. In our clinic, we made a seccess in treatment of the scissors bite using the Schwarz appliance. We treated the scissors bite using the lower Schwarz appliance for a mean observation period of 21 months. The subjects were 2 boys, aged 4 years.

Recently, paper strength properties come up to be lowered by increasing ratio of utilization of recycling paper. In order to overcome these problems, strengthening agents which may cause enviromental problems have been used. Therefore, acrylamide was added to starch which is a cheap natural polymer, carbamoylethyl starch(CES) with high activity was prepared, and so the applicability as a paper additive was examined. The results are following; FT-IR spectra of CES of which degree of substitution was 0.25 showed strong C=O band at 1680㎝^-1 which corresponds the carbonyl group n amides(amide Ⅰ). Analysis of bravender viscosity showed that cooking start point of CES is 60℃ and instant viscosity is 830 B.U.(bravender unit). Effect of carbamoylethl DS on strength properties was resulted that CES of DS 0.20 appeared to be the best choice for making handsheets from KOCC with good overall strength properties, and it was selected as standard sample. Effect of pH on strength properties was obvious for their increasing values as decreasing pH. Also, a 5-fold increase in size rate as well as significant increase in wet-tensile strength were obtained in handsheets from KOCC by 3% wet-end addition of CES.

이 연구의 목적은 농업생명과학대학 교수들이 과목 지도에서 활용하는 교수전략, 방법 및 전략을 확인하는데 있었다. 연구 목적을 달성하기 위해 총 46개 대학에 근무하는 1,471명의 교수 중 307명을 단순무선표집하여 설문조사를 실시하였다. 주요 연구 결과는 다음과 같다. 첫째, 농학계 대학 교수들은 교수능력을 개발하기 위한 기회가 부족한 편이며, 교육방법에 대한 학습경험이 적은 편이다. 둘째, 농학계 대학 교수들은 사전에 수업운영에 대한 구상은 하지만 실제적인 지도계획 수립이나 구체적인 자료준비는 부족하며, 수업을 위한 교안 작성자는 과반수에 지나지 않았다. 셋째, 농학계 대학 교수들은 강의법, 실험 및 실습 등의 한정된 수업방법을 주로 활용하나 최근에 강조되는 학습자 중심 교수방법들의 활용은 부족한 것으로 나타났고, 실제 수업 단계에서 특히 수업 도입이나 마무리 단계가 미흡한 것으로 나타났다. 넷째, 농학계 대학 교수들은 학생 강의평가 결과를 수업개선에 적극적으로 활용하지 않으며, 강의평가를 제외한 대학차원의 교수개선 지원이 부족하다. 이러한 결과에 기초하여 이 연구에서는 농업 및 농촌 현장과 연계된 교육, 교육목표에 적절한 교수설계, 학습자 중심의 교수방법 활용, 강의부담 경감, 교수 전문성 향상을 위한 기회 및 지원 제공 등의 개선방안을 제안하였다. The purpose of this study was to identify the instructional designs, teaching methods and strategies used by professors in the college of agriculture and life sciences in Korea. The population for this study was 1,471 professors of agriculture and life science colleges. 307 professors were randomly chosen from the population for the study. The survey was carried out by e-mail or in person. The major findings of this study were as follows: First, professors of colleges of agriculture and life sciences do not have many opportunities to improve their own teaching abilities. Also, they do not have many training experiences in taking pedagogy class, and attending seminars and workshops. Second, professors do not make an actual lesson plan or prepare enough learning aids materials on a class period base. Third, the professors rarely used the more learner-centered approaches. In addition, they usually emphasized on the "body stage" of each lesson which resulted in the unbalanced instruction in the "opening" and the "closing stages" of the lesson. Finally, professors execute the course evaluation, but the results of these evaluations are not being used for improvement of teaching and learning. Based on these results, some recommendations were made: the field-related education in agriculture, proper systematic design of the course teaching, use of more learner-centered teaching methods, building the constructive environment for the professors by reducing mandatory lectures and the balanced teaching from the opening to the closing in every instruction.

목적 : 재발성 난소암에서 platinum 감수성을 기준으로 2차 항암요법으로 사용한 Carboplatin과 Paclitaxel의 효과를 알아보기 위하여 본 연구를 진행하였다. 연구방법 : 1998년 1월 1일부터 2003년 8월 31일까지 만 5년 8개월 간 아주대학교병원 산부인과에 재발성 난소암으로 입원한 환자 중에서 최초 수술로 난소암을 확진한 후 Cisplatin 또는 Carboplatin 등 platinum 제재가 포함된 항암치료를 받은 후 6개월 이후에 재발한 환자 29명을 대상으로 Carboplatin은 5 AUC를 그리고 Paclitaxel은 175 mg/m^(2)를 투여하였으며, 최소 3회에서 최고 16회까지 투여하였다. 치료효과의 판정은 CT, MRI, Ultrasonography등 영상진단상 암종괴의 크기가 완전히 소실되었을 경우를 완전반응(complete response)으로, 50%이상 감소되었을 경우를 부분반응(partial response)으로, 50% 미만으로 감소되었거나 20% 미만 증가하였을 경우를 불변(stable disease)으로, 그리고 20% 이상 증가되었을 경우를 진행(progressive disease)로 정의하였다. 결과 : 대상 환자에서 완전반응은 6명(21%), 부분반응은 11명(38%), 그리고 불변은 5명(17%)로 전체 반응율 (overall response rate)은 59% 그리고 임상적 유용성(clinical benefit=CR+PR+SD)은 76%이었다. 결론 : 재발성 난소암환자에서 기왕에 사용한 Platinum 제재에 민감한 환자에서는 Carboplatin과 Paclitaxel의 병행 투여가 효과적이었다. Objective : To ascertain the effect of Carboplatin and Paclitaxel combination as a second line regimen for recurrent ovarian carcinoma based on platinum sensitivity. Methods : From January 1st, 1998 through to August 31st, 2003, 29 patients were retrospectively reviewed who had previously underwent primary cytoreductive surgery and adjuvant chemotherapy with Cisplatin or Carboplatin for ovarian carcinoma, and who had later recurred during follow up. All 29 patients had recurred at least 6 months after therapy, and thereafter received second line chemotherapy consisting of Carboplatin (5 AUC) and Paclitaxel (175 mg/㎡) for a minimum of least 3 cycles and a maximum of 16 cycles. Treatment efficacy was assessed by imaging studies including Computerized tomography, Magnetic Resonance Imaging, or Ultrasonography. Complete response was determined as complete disappearance of tumor, partial response at least than 50% reduction in tumor volume, stable disease as less than 50% reduction or less than 20% increase in tumor volume, and progressive disease as more than 20% increase. Results : There was complete response in 6 (21%) patients, partial response in 11 (38%), stable disease in 5 (17%), showing an overall response rate of 59%. The clinical benefit (CR+PR+SD) was 76%. Conclusion : The combination of Carboplatin and Paclitaxel administration seems to be an effective mode of second line therapy in patients with recurrent ovarian carcinoma who had been sensitive to prior platinum based chemotherapy.

A case of a 46-year-old Korean male with post-stroke insomnia that induced by intracranial hemorrhage was presented. He was treated with Transcutaneous electric acupoint stimulation (TEAS) at BL62 and KI6 once per a day for 17 days. We recorded the patient's sleep time and time of asleep, and used PSQI-K to assess severity of patient's insomnia symptom. After using TEAS, there was improvement in patient's insomnia severity and the time of sleep. From the result of this case, electrical stimulation at acupoint can may be effective in treating post-stroke insomnia.
