이 연구는 과학캠프 참여 경험이 과학영재들의 창의적 인성과 문제해결력에 영향을 미치는지 알아보기 위한 것이다. 이를 위해 J대학교 부설 과학영재교육원에 소속된 69명의 중등 과학영재들을 대상으로 여름 방학 중 3박 4일간 과학캠프 활동을 실시하였다. 캠프 활동 전후의 사전사후검사를 통해 과학영재들의 창의적 인성을 t-test를 통해 살펴보았다. 사전 사후 검사에는 5점 Likert 척도 문항을 적용하였다. 창의적 인성 검사를 분석한 결과 사전 검사 평균 3.88점, 사후 검사 평균 3.97점으로 사후검사 평균이 사전검사보다 높게 나타났다. 사전 검사에서는 창의적 인성의 하위 요소 중 자신감이 가장 높게 나타났다. 사후검사에서는 독립성이 가장 높았다. 사전 검사와 사후 검사간 차이를 알아보기 위해 t-test를 실시하였다. 창의적 인성의 하위 요소별 t-test를 실시한 결과 자신감, 인내/끈기, 상상력, 독립심, 모험심, 개방성, 유머감은 사후검사가 유의미하게 높은 것으로 나타났다. 과학영재들의, 전공영역과 성별에 따른 t-test 분석에서는 유의미한 차이가 나타나지 않았다. 호기심을 제외한 창의적 인성의 전 영역에서 통계적으로 유의미한 차이가 나타난 것은 과학캠프 활동이 과학영재들의 창의적 인성 함양에 긍정적인 영향을 미쳤음을 보여주는 것이다. 문제해결력 사전검사 평균 2.12점, 사후검사평균 2.00점이었고, t-test 결과 유의미한 차이가 나타나지 않았다. 과학영재들을 대상으로 한 과학캠프활동에 대한 인식 조사에서는 캠프 활동에 대한 긍정 응답이 매우 높게 나타났다. 이와 같은 결과는 과학영재 프로그램 개발 과정에서 캠프 활동 등의 다양한 교육 경험을 확대할 필요가 있음을 보여주는 것이다. The purpose of this study is to investigate the effects of science camp activities on the creative personality and problem solving ability of scientifically gifted students. A science camp was operated with the participation of 69 scientifically gifted students for four days and three nights at the Science Gifted Education Center affiliated with J University. A pretest and a posttest were conducted regarding their creative personality before and after the camp activities, and any differences between the results of the two tests were analyzed. A five-point Likert scale was applied to the pretest and posttest questionnaires. The mean creative personality score was 3.88 points in the pretest and 3.97 points in the posttest, showing a higher score in the posttest. In the pretest, self-confidence recorded the highest score among the subelements of creative personality. In the posttest, independence marked the highest score. The t-test was performed to examine differences between the pretest and posttest results, and showed statistically significant differences in self-confidence, patience/persistence, imagination, independence, adventurous spirit, openness, and sense of humor. An analysis according to the science-gifted students’ major fields of study and gender exhibited no statistically significant differences between the pre-test and post-test. The statistically significant difference shown in every subelement of creative personality except curiosity suggests that the experience of science camp activities has positive effects on the cultivation of creative personality in scientifically gifted students. In the problem solving ability test, the pretest average was 2.12 and the post test was 2.00. In the result of t-test, there was no significant difference between pre-test and post-test. In the perception survey on science camp activities, scientifically gifted students respond positively to science camp activities. These results suggest the need for expanding educational experiences that allow the active participation of scientifically gifted students, such as science camps, in the process of developing educational programs for scientifically gifted students.

Carcinoma ex pleomorphic adenoma is transformed at the incidence of 1-20% in pleomorphic adenoma and frequently recurred. It accounts for 10% of all malignant salivary tumors and its average age of occurrence is 60s. It will present in a large, long-standing pleomorphic adenoma or in one that was previously treated but has recurred. According to cell composition in malignant cell carcinoma, and clear cell adenocarcinoma. Most (75%) occur in parotid gland, while about 20% occur in the minor gland of the oral mucosa. The metastasis rate to regional lymph node is about 25%, and to distant organs about 33% and the 5-year survival rates are 40%. Though the treatment of the carcinoma ex pleomorphic adenoma is not established, it is treated ideally with and extensive resection, neck dissection, postoperative radiotherapy, and chemotherapy. When occurred in parotid gland, facial paralysis is reported. With a review of literatures, we report a case of carcinoma ex pleomorphic adenoma which operated with total parotidectomy and supraomohyoid neck dissection.

Hee-mi Lee,Nam Lyong Kang,이상칠,최상돈 한국물리학회 2007 THE JOURNAL OF THE KOREAN PHYSICAL SOCIETY Vol.51 No.III

Screening effects on absorption powers for systems of electrons interacting with longitudinal optical phonons in quasi-two-dimensional quantum well structures are examined theoretically by using a quantum-statistical operator algebra technique. We find for GaN that the absorption power for both a square well and a triangular well is keenly affected by the screening in such a way that the power increases, but the width decreases, with the electron density.

Purpose: The purpose of this retrospective clinical study was to monitor the outcomes of periapical surgery in periapically infected tooth with or without retrograde filling materials (MTA or IRM). Patients and Methods: A total of 85 teeth in 63 patients were included in the study between November 2004 and August 2008. Randomly, MTA or IRM was used as a retrograde filling material or only apical resection without retrograde filling. Teeth with advanced periodontal bone loss or presence of root fracture were excluded from the study. The patients were subjected to a minimum follow-up period of 12 months, with a mean of 17.1 months. Results: Successful healing was observed in 83.3% of the MTA-treated teeth, 80% of the IRM-treated teeth and 75% of the teeth which was not retrograde filling. Doubtful healing was seen 9.3% (MTA), 13.3% (IRM), 12.5% (no retro-filling). The success rate of upper incisors (92%) was higher than lower lincisor and molars (66.7% and 50%, respectively). Conclusion: In this study, periapical surgery including retrograde filling improves the prognosis. And, no statistically significant differences were found between retrograde filling materials (MTA or IRM).

Purpose: Patients who had a subcondylar fracture with a displaced or deviated condylar segment were treated with a retromandibular approach (RMA) or an endoscope-assisted transoral approach (EATA) in our department of oral and maxillofacial surgery. The clinical results of the approaches were compared. A comparative study of specific approaches for subcondylar fractures has not been published before in Korea. Methods: Twenty-one patients with subcondylar fractures of the mandible were included. Ten patients were treated with the retromandibular approach and 11 were treated with an endoscope-assisted transoral approach. We examined patient age, gender, fracture sites, classifications, period of maxillomandibular fixation, facial nerve (FN) or greater auricular nerve (GAN) injuries, maximal mouth opening, deflection, occlusal changes, number of plates, follow-up period, and other complications. Preoperative computed tomography and pre-operative, post-operative, and follow-up panoramic views were taken of each patient. Results: Mean maximal mouth openings were similar between the two approaches. FN and GAN injuries were more frequent in the RMA group but the deflective rate with mouth opening was higher in the EATA than that in RMA group. Two cases of post-operative infection occurred in the EATA group, and occlusal changes were observed in one case for both approaches. Conclusion: The RMA offers more direct access and visualization of the surgical field but it can cause scars and retractive injuries of the FN and GAN. But, EATA did not result in consequent nerve injuries or scars postoperatively, but unfavorable fractures such as $medial$ $override$ condyles were more difficult to reduce endoscopically. Except cases of an expected difficult reduction, the treatment of choice for a displaced subcondylar fracture may be an EATA.

N/A Objectives: Arteriovenous fistula (AVF) is Achilles hill of patients receiving maintenance hemodialysis, but thrombosis of AVF is a frequently encountered problem in maintenance hemodialysis patients. AVF thrombosis or occlusion is known to be associated with old age, underlying diabetes mellitus, increased fibrinogen and factor VIII, short AVF maturation time, low dialyzer blood flow, etc. Recently, several reports suggested that high titer of IgG anticardiolipin antibody (IgG-ACA) is associated with single or repeated clotting of AVF and elevated Lp(a) level is associated with vascular access occlusion in patients under maintenance hemodialysis. This study is to investigate the relationship between AVF thrombosis and the presence of elevated titiers of LP (a) and IgG-ACA. Methods: This study included 20 patients with end stage renal disease under hemodialysis via AVF. Ten subjects have had one or more episodes of AVF obstruction (group A). Another 10 subjects without episodes of AVF obstruction (group B) were selected matching with age, sex, underlying disease, duration of hemodialysis, blood glucose level and lipid profile of subjects in group A. The IgG, IgM anticardiolipin antibody titers with indirect ELISA method and LP (a) level with turbidimetric assay were measured and analysed. Results: Four subjects in group A showed positive IgG-ACA titer what of all subjects in group B were negative titer (p=0.03). Only one subject in group A and two subjects in group B showed positive IgM-ACA titer (p>0.05). The median value of Lp (a) was 32.75 (mg/dl), 43.1 (mg/dl) in group A and group B respectively and was not significantly different each other (p>0.05). Conclusions: In end stage renal patients receiving hemodialysis, positive IgG-ACA titier seems to be an independent risk factor of AVF thrombosis.

Ameloblastoma is an aggressive benign odontogenic epithelial tumour that may arise from the enamel organ, remnants of dental lamina, or the lining of an odontogenic cyst. It is usually categorized into solid or multicystic, unicystic, and peripheral types. Treatment ofameloblastomas include conservative methods such as marsupialisation, enucleation, and curettage; and radical treatments such as marginal or segmental resection. Radical treatments have resulted in lower recurrence rates; however, may also encounter esthetic, functional, and reconstructive problems. Unicystic ameloblastoma has been considered less aggressive and a lower recurrence tendency. Thus, many authors have recommended conservative treatment in cases of unicystic ameloblastoma. An 11 year-old boy presented with displaced second and third molars by luminal unicystic ameloblastoma in the mandible. Cyst enucleation, curettage, and third molar extraction were done. No signs of recurrence or esthetic problems such as facial asymmetry were seen radiologically and clinically, up to 8 years 2 months postoperatively.

Growth of HVPE-GaN/InGaN Heterostructure on r-Plane Sapphire Substrate

안형수,S. L. Hwang,C. H. Lee,H. S. Jeon,K. H. Kim,M. Yang,이상칠,김석환 한국물리학회 2007 THE JOURNAL OF THE KOREAN PHYSICAL SOCIETY Vol.51 No.III

GaN/InGaN heterostructure on r-plane Al$_2$O$_3$ substrate is grown by mixed-source hydride vapor phase epitaxy (HVPE). The InGaN/GaN heterostructure is grown by a selective-area growth (SAG) method. The heterostructure consists of an undoped GaN layer, an InGaN layer, and a Mg-GaN layer. NH$_3$ and gallium (or indium) chloride formed with HCl, which is flowed over for a mixed source, are used as gallium (or indium) and nitrogen sources. The gas flow rates of HCl and NH$_3$ are maintained at 10 sccm and 500 sccm, respectively. The temperature of the GaN source zone is 650 $^\circ$C. In the case of the InGaN, the temperature of the source zone is 900 $^\circ$C. The growth temperatures of the GaN and InGaN layers are 820 $^\circ$C and 850 $^\circ$C, respectively. The electroluminescence (EL) peak of the GaN/InGaN heterostructure is 468 nm and the full width at half maximum (FWHM) is 89.7 nm. These results demonstrate that the heterostructure of III-nitrides on r-plane sapphire can be successfully grown by mixed-source HVPE.
