이 연구는 중등교원양성 교육과정을 개선하고 학교 현장과의 유기적 연계를 모색하기 위하여 중등교원양성 교육과정의 교육현장 적합성을 분석하고, 이를 높이기 위한 방안을 탐색하였다. 연구목적을 달성하기 위하여 과학, 수학 교사를 대상으로 한 설문조사와 교수 및 교사를 대상으로 전문가집단면담(Focus Group Interview)을 실시하였다. 이 연구에 의하면 중등교원양성 교육과정은 ‘투철한 교직관’을 함양하고, ‘교과전문성’ 역량을 충족시킴으로써 교육자의 자질과 전문성을 높이는 데 기여하고 있다. 그러나 중등교원양성과정은 학교업무와 교수학습사태의 실제, 학생에 대한 이해 및 상담, 진로 지도 등의 실천적 역량 함양에 있어서는 다소 미흡한 것으로 나타났다. 또한, 면담 결과에 의하면 중등교원양성 교육과정의 현장 적합성이 낮게 나타나는 이유로 교육 시간의 부족과 대규모 강의, 학습자의 능동적 참여 감소, 통합적 교과내용의 증가, 이론과 현장의 괴리 등의 문제점이 제기되었다. 전문가집단면담의 결과, 교원양성과정의 장기적 개선방안을 마련하기 위하여 검토가 필요한 사항으로는 교과내용학적 관점에서 교원양성 교육과정의 학문적 정체성 정립, 교과교육학의 관점에서 예비 교사 교육의 수준과 범위의 재설정 등을 제안하고 있다. The purpose of this study is to explore the suitability of secondary school teacher education curriculum on science and math subjects in actual school site. For analysis, this study analyzed survey which measured secondary school teachers’ demands for site suitability and also the study conducted focus group interview to support the finding. According to the survey results, teachers responded that their teacher education curriculum did not provide direct effect on their teaching practice but the major course education played relatively more important role. Also, it was found that teachers were perceiving that their teacher education curriculum helped them improving teaching philosophy and subject professionalism. However, the curriculum was not sufficient for improving various practical matters such as school administrative works, student consulting skills and career advise. According to the focus group interview, participants perceived various environmental changes such as lack of training hours, large size lecture, change in learner"s participatory attitude, gap between theory and practice and introduction of new theories into school curriculum. This study suggested following policy implication that can improve the site suitability of teacher education such as providing activities based on student development, educating teachers to teach core concepts for students and integrate various subjects. Lastly, main issues regarding site suitability was found as following such as necessity of designing curriculum that considers career uncertainty of teacher"s college students, defining academic characteristics of science and math education and reinforcing teacher education curriculum-professional training program relations

Background: The optimal treatment for patients with non-small cell lung cancer (NSCLC) with neurologically symptomatic, synchronous brain metastasis still remains controversial. The aim of this study was to analyze our experience with surgical treatment in these patients. Methods: The study was a retrospective review of 25 patients presented with neurologic symptoms, synchronous and multiple or solitary brain metastasis from NSCLC between Apr, 2006 and Dec, 2011. Patients were divided into two groups according to performing neurosurgery for brain metastasis: surgical treatment group (n=12) and non-surgical treatment group (n=13). We compared surgical group with non-surgical group and analyzed overall survival, clinical course, prognostic factors and treatment primary tumor and brain metastasis between two groups. Results: The mean age of the patients was 65.8 years. The histological types included 18 adenocarcinomas, 4 squamous cell carcinoma, 3 NSCLC-not otherwise specified. 11 patients of surgical group received upfront neurosurgical resection for brain metastasis followed by WBRT or stereotactic radiosurgery and 10 patients of non-surgical group received WBRT or stereotactic radiosurgery only. There was no significant difference in overall survival among two groups (surgical group, 11.6 months versus non-surgical group, 10.5 months, respectively; P=0.14). Conclusion: Patients with brain metastases, presenting with neurologic symptoms, showed no survival benefit from combined treatment with neurosurgical resection, although local brain metastasis was improved.

Purpose: To investigate the surgical results of repeated trabeculectomy in primary congenital glaucoma. Methods: The authors retrospectively reviewed the data of 16 patients (23 eyes) who underwent two or more trabeculectomies with or without mitomycin C for primary congenital glaucoma between 1990 and 2004. Surgical success rate and postoperative complications were assessed. The relationship between the use of mitomycin C and the surgical outcomes was also studied. Results: Among the 23 eyes, 10 had a history of previously failed goniotomy or trabeculotomy and 6 eyes had undergone trabeculectomy more than 3 times. The overall success rate of repeated trabeculectomy was 63.9% and the success rate of the 14 eyes operated on with mitomycin C was not higher than that of the 9 eyes that did not receive mitomycin C (p=0.166). Two eyes were reported to have postoperative hypotony and there was one case of endophthalmitis after trabeculectomy; however, the use of mitomycin C did not increase the overall rate of surgical complication (p=1.00). Conclusions: Repeated trabeculectomy can be considered as a procedure to treat primary congenital glaucoma, particularly in severe cases of congenital glaucoma.

An optimal reaction condition for producing cycloamylose (CA) from sweet potato starch was investigated using a combination of isoamylase (from Pseudomonas sp.) and 4-α-glucanotransferase (from Thermus aquaticus, TAαGT). Starch was debranched by isoamylase for 8 h and subsequently reacted with TAαGT for 12 h. The yield and purity of CA products were determined using HPSEC and MALDI-TOFMS, respectively. Consequently, the maximum yield was 48.56%, exhibiting the highest CA production efficiency ever reported from starch. The CA products showed a wide range of the degree of polymerization (DP) with the minimum DP of 5. CA was also produced by simultaneous treatment of isoamylase and TAαGT. The yield was 3.31%, and the final products were contaminated by multiple branched and linear molecules. This result suggests that a former reaction condition (the sequential addition of isoamylase and TAαGT) is preferable for producing CA from sweet potato starch.

We report a case of partial anomalous pulmonary venous return where the right upper and lower pulmonary veins drain into the coronary sinus with right-to-left shunt via patent foramen ovale. To our knowledge, this is the uncommon case where the interatrial septum is intact. The diagnosis was initially made by transthoracic echocardiography and transesophageal echocardiography with the infusion of agitated saline and confirmed by pulmonary artery angiography. Curative operation could not be performed because of the irreversible pulmonary hypertension.
