본 연구의 목적은 동국대학교의 교수들이 수행하고 있는 교수학습 방식을 파악하고 각 방법들의 효과성을 교수들이 어떻게 인식하고 있는지를 알아 보고자 하였으며 창의적 교수학습방법개발에 대한 교수들의 요구를 파악하여 교수학습개발센터의 프로그램개발을 위한 기초자료로 삼고자 하였다. 수업방식에 있어서 전공, 교양을 막론하고 대부분이 강의식 수업방식이 높았으며(80.9%, 86%), 발표식, 토론식이 (14%, 18.6%) 실험실습 등이 그 다음으로 나타났다. 교수들은 전공과목보다는 교양수업에서 학생들의 요구에 맞는 수업 수업방식을 고려하고 있는 반면 수업방식의 효과에 대해 53%만이 효과적이라고 보고하고 있다. 교수들도 효과적인 강의방법 등 교수법에 대해 체계적으로 학습할 필요성을 느끼고 있었다. 강의 기술(교수방법)과 토론 중심 수업 방법에 대한 워크샵에 대한 요구가 가장 높게 나타났고 발표수업과 프로젝트수업 방법 등 강의식 수업 이외의 다른 수업방식에 대한 워크샵 요구도가 높았다. 그 외에 학교의 지원에 대해서는 첨단 수업 기자재 활용을 위한 보조자(조교)에 대한 요구도가 가장 높고 강의 운영을 위한 보조금, 개인별 상담 지원 순으로 요구도가 높게 나타났다. The purpose of this study was to comprehend the methods of teaching and learning carried out by the teachers of Dongguk University, and to find out how the professors found those methods effective. This research was also used to serve as a basis for the development of a more creative teaching-learning system to enhance better programs for the Professor Teaching-Learning Development Center. In teaching methods, regardless of classes for majors or for cultural enrichment, most of the courses were in the form of lectures (80.9%, 86%) followed by research and discussion (14%, 18.6%), with experiment and practical training coming in third. Although professors tend to choose a more student-oriented class method in distribution courses more than in major courses, it was reported that only 53% of the faculty claimed this class method to be effective. The faculty felt the need for professors to have more constructive learning in incorporating more effective teaching methods. The demand for professor workshops on teaching skills (teaching methods) and discussion oriented classes proved to be high, as well as the need for workshops on teaching methods other than lectures, such as research courses and project oriented class methods. Regarding other demands for university support, the demand for an assistant (assistant teacher) to help with the new technology equipment was the highest, followed by subsidies for course management and support in individual counseling.

Objectives: This study sought to evaluate fixation methods and determine the best method for the postoperative stabilization of maxillary osteotomy. For our analysis we performed a three-dimensional finite element analysis of stress distribution on the plate, screw, and surrounding bone, as well as displacement onto the plate. Materials and Methods: We generated a model using synthetic skull scan data; an initital surface model was changed to a solid model using software. Modified anterior segmental osteotomy (using Park’s method) was made using the program, and four different types of fixation methods were used. An anterior load of 100 N was applied on the palatal surface of two central incisors. Results: The Type 1 (L-shaped) fixation method gave stresses of 187.8 MPa at the plate, 45.8 MPa at the screw, and 15.4 MPa at the bone around the plate. The Type 2 (I-shaped) fixation method gave stresses of 186.6 MPa at the plate, 75.7 MPa at the screw, and 13.8 MPa at the bone around the plate. The Type 3 (inverted L-shaped) fixation method gave stresses of 28.6 MPa at the plate, 29.9 MPa at the screw, and 15.3 MPa at the bone around the plate. The Type 4 (I-shaped) fixation method gave stresses of 34.8 MPa at the plate, 36.9 MPa at the screw, and 14.9 MPa at the bone around the plate. The deflection of the plates for the four fixation methods was 0.014 mm, 0.022 mm, 0.017 mm, and 0.018 mm, respectively. Conclusion: The Type 3 (inverted L-shaped) fixation method offers more stability than the other fixation methods. We therefore recommend this method for the postoperative stabilization of maxillary osteotomy.

In this study, Performance of muffler is studied at constant velocity of carbureted 4 stroke engine. Pressure fluctuation was measured by pressure transducer at muffler, and performance of a muffler was investigated through transfer function analysis by analyzer. The experimental results show that remarkable attenuation in exhaust noise was accomplished and characteristics of muffler was discussed in detail in connection with associated experimental data.

Ti-2B-Fe system ceramics were synthesized from the mixture of metal titanium, boron and iron powder by SHS method. The powders and sintered body were not appeared the second phase. Grain growth of TiB₂increased with increasing the iron content but grain size were smaller than starting raw materials. The relative density of TiB₂-2wt% Fe composition sintered at 1900℃ for 60min by pressureless sintering were 85% and the sintered properties were the most excellent at 2wt% Fe content in TiB₂-Fe system.

다른 종류의 재료들이 접합되었을 때 접합부위의 코너에는 응력의 급격한 증가가 나타났다. 이의 해석을 위해 기존의 유한요소법보다 효율적인 SBD(specified boundary displacement)방법을 통해 구조용 접합재를 사용한 더블랩 죠인트에 대한 응력 singularity에 대해 연구하였다. 이 방법은 응력이 급격히 증가되는 국부의 해석에 매우 효율적인 방법임을 보여준다.

The notched charpy and Izod impact test is the most prevalent technique used to characterize the effect of high impulse loads on ploymeric materials. A method of analysis in rubber toughened PVC is suggested to evaluate the critical strain energy release rate Gc from the Charpy and Izod impact energy measurement. Instrumented Charpy impact tester was used to extract ancilliary information concerning fracture properties in addition to total fracture properties and maximum critical load. The stress intensity factor Kd was calculated for the variation of rubber contents from the obtained maximum critical load and toughned effects were investigated.

Carcinoid tumors have been reported in a wide range of organs but most commonly involve the lungs, bronchi and gastrointestinal tract. Within the gastrointestinal tract, appendix is the most common location for carcinoid, followed by the distal small intestine, the rectum, and the stomach. Among these, primary involvement of the ampulla of Vater is extremely rare. We report a case of carcinoid tumor of ampulla of Vater. A 62-year-old man presented with epigastric soreness. Gastroduodenal endoscopy showed hyperemic bulging mass on ampulla of Vater and diagnosed as carcinoid tumor by histologic finding, with immunohistochemical study. In ^(111)In-octreoscan, tumor had regional lymph node metastasis, but no evidence of distant metastasis. Pancreatoduodenectomy with lymph node dissection was performed.

朴世蔓,朴明均,柳正烈 明知大學校 産業技術硏究所 2005 産業技術硏究所論文集 Vol.24 No.-

Thermal conductivity and specific heat of four kinds of dry sand molds, main aggregates of which were silica, olivine, zircon and chromite sands, were measured from room temperature to about 1,000℃. The values of thermal conductivity of the molds which consisted of silica, zircon, chromite sands decrease gradually from room temperature to 1,000℃. The mean values of thermal conductivity of these molds are 0.0015 CGS unit for silica sand, 0.0018 CGS unit for olivine sand, 0.0021 CGS unit for zircon sand and 0.0018 CGS unit for chromite sand. The values of specific heat of all the above mentioned sand molds increase as temperature increases, but the rate of the increase drops with increasing temperature. The mean values (25-1, 300℃) of specific heat of these molds are 0.25 CGS unit for silica sand, 0.26 CGS unit for olivine sand, 0.18 CGS unit for zircon sand and 0.21 CGS unit for chromite sand. With the measured values of thermal conductivity, specific heat and mold density, thermal diffusibility and heat diffusibility of each mold were calculated and used for thermal analysis when molten steel was poured into the mold. Near the interface between cast metal and sand mold, the mold temperature became lower in the order of the magnitude of its heat diffusibility, namely silica sand, olivine sand, chromite sand, zircon sand. But in remote areas from the interface, the mold temperature became higher in the order of the magnitude of its thermal diffusibility, namely chromite sand, olivine sand, silica sand, zircon sand.
