自己?能理論의 動機觀과 硏究動向

권대훈 안동대학 학생지도연구소 1988 學生指導硏究 Vol.8 No.1

This article examines motivational perspective of Bandura's self-efficacy theory and reviews recent research articles which was performed to test its predictions in academic achievement situations. First, motivational perspective of self-efficacy framework is discussed Self-efficacy refers to personal judgment about one's capability to organize and implement behavior in specific situations. As a proximal mediating mechanism, self-efficacy is hypothesized to influence task motivation (effort expenditure and persistence), choice of activities, and thought patterns people acquire their efficacy information from their performance accomplishments, vicarious experiences, verbal persuasion, and their physiological states. People judge (percept) their efficacy in specific situations through inferential process in which these information are weighted and integrated with respect to various efficacy cues such as perceived ability, effort expenditure, external aids, outcome patterns. Second, self-efficacy perspective is compared with locus of control, attribution theory, self-worth theory, and learned helplessness. Third, recent studies performed under the rubric of self-efficacy are divided into those upon student efficacy and those upon teacher efficacy, and reviewed separately. Studies which successfully enhanced student self-efficacy are reviewed under the headings of reward, attributional feedback, goal-setting, social comparision, and strategy training with their educational implications. And the nature, antecedents, and consequences of teacher efficacy are discussed according to the self-efficacy framework. Also the relations of student efficacy, teacher efficacy, achievement, and other related variables are explored. Finally, some directions for future research are suggested.

불소가 첨가된 실리콘 산화막의 다층금속절연 특성에 관한 연구

權大赫,南基泓,吳相光 慶一大學校 1997 論文集 Vol.14 No.2

The characteristics of fluorinated silicon oxide (SiOF) films prepared by plasma enhanced chemical vapor deposition(PECVD) were discussed. The deposition of these films was carried out in the temperature range of 80 - 220℃ in a conventional parallel plate plasma reactor with 〈 ±3% uniformity by flowing 2 sccm of disilane (Si₂H6), 100 sccm of nitrous oxide (N₂O), and 20 sccm of tetrafluoromethane (CF₄). AS the deposition temperature increased from 80 to 220℃, the deposition rate of the films increased from 16.7 to 18.4 nm/min; meanwhile, the etch rate decreased from 2.69 to 1.48 nm/sec. The refractive index was 1.46 regardless of the deposition temperature. The Fourier transform infrared (FTIR) spectra of the films showed decreasing Si-O stretching wave number with increasing full width at half maximum (FWHM) as deposition temperature increased. The high frequency capacitance-voltage (C-V) measurements of the metal-oxide-semiconductor (MOS) capacitors fabricated using the films showed increasing effective oxide charge density and decreasing dielectric constant with increasing deposition temperature. Deposition temperature of 180℃ resulted in films with the smallest dielectric constant of 3.75. These films showed an average breakdown strength of 9.14 MV/cm with 77.5% of the MOS capacitors having breakdown field strength ≥9.5 MV/cm

활성탄충진여상에 의한 고농도 암모니아함유폐수의 처리에 관한 연구

權大原 대구산업정보대학 1997 논문집 Vol.11 No.2

The purpose of this study, which uses activated carbon for the trickling filter media at the room temperature by the trickling filter, which uses effluence of the depressurized evaporation night-soil treatment method containing high strength ammonium nitrogen(>600 mg·l^(-1)) for the substrate, is to investigate the removal rate of organic matter and ammonium nitrogen, the inhibition of ammonium nitrogen in room temperature for 1 year. The results are as follows ; Using activated carbon for the trickling filter media, the removal rate of COD at the COD load of 1.0~1.46 kg·m^(-3)day^(-1) was more than 90%. The removal rate was not influenced by the concentration of influent ammonium nitrogen which increased to 100~670 mg·l^(-1) in room temperature(9~25℃). The removal rate of ammonium nitrogen was influenced by the change of temperature. The removal rate of ammonium nitrogen showed 47% at the temperature of 25℃, 10% at 15℃. In the case of wastewater containing high strength ammonium nitrogen, we can get a high removal rate of organic matter by using activated carbon for the trickling filter media. Not damaging by the psychoda alternata larvae, the activated carbon can be used for filter media of trickling filter.

To enlarge the spatial structure for dense and compact land use. b. To allocate appropriately urb in functions to enforcing the urban locational service. c. To establish political strategy to solve the land use systemizing for the management and effectiveness.

상악골과 비사골동에 이환된 백악질 골화성 섬유종(cemento-ssifying fibroma)의 치험례

권대현,김신유,남정순,구명숙,이봉서,권대근,김종배 大韓顎顔面成形再建外科學會 2001 Maxillofacial Plastic Reconstructive Surgery Vol.23 No.6

The cemento-ossifying fibroma is a benign fibro-osseous tumor that may behave in an aggressive pattern. Although found predominantly in the mandible, most of these unusual tumors may arise in the maxilla and paranasal sinuses. Especially these lesion in the maxilla and sinuses behave more aggressively and are more prone to recur compared to mandibular counterparts. Therefore, more radical approach may be recommended than expectant observation or curettage in the initial management of this neoplasm. This is a case report of cemento-ossifying fibroma extended to maxillary sinus and naso-ethmoidal area treated by wide surgical excision after repeated conservative treatments.

引張拘束 龜裂試驗에 依한 ABS EH32鋼 熔接部의 低溫龜裂 感受性

權海旭,金大憲,金星秀 영남대학교 공업기술연구소 1984 연구보고 Vol.12 No.1

Cracking of the welded zone of high strength steel is one of the most important factors of weldability and many kinds of test methods have been proposed to study that. In this study, cold cracking susceptibility of welded zone for high strength steel (ABS EH32 steel) with the shielded metal are welding was investigated by the tensile restraint cracking test. Effects of diffects of diffusible hydrogen contents on root cracking, lower critical stress, crack initiation and fracture method, hardness distribution of the welded zone and fractography were mainly investigated. The wet electrodes with higher diffusible hydrogen contents showed lower the critical lower stress level than the dried ones. Because of the hydrogen embrittlement, the heat affected zone by using the wet electrodes had higher hardness values than that by using the dried ones. Fracture surface of the heat affected zone with the wet electrodes showed mainly brittle fracture (intergranular and cleavage) and that of the weld metal also showed partially that due to the hydrogen embrittlement.

하악골에 전이된 소세포암 (small cell carcinoma) : 증례보고 A CASE REPORT

권대현,김종배 大韓顎顔面成形再建外科學會 2002 Maxillofacial Plastic Reconstructive Surgery Vol.24 No.5

The small cell carcinoma has the most aggressive clinical course of any type of pulmonary tumor with median survival from diagnosis of only 2 to 4 months, and is a very rare in oral cancer. Because of the high malignant potency, small cell carcinoma has a greater tendency to be widely disseminated by the time of diagnosis and chemotherapy for the primary therapy is accepted generally. However, distant metastasis to mandible is very rare and only 5 cases had been reported according to the literature review We experienced a case of small cell carcinoma metastasized to mandible ramus and condyle. The patient was 67 year-old male with multiple lymph node metastasis and managed with chemotherapy, who was died of tumor 2 months after the initial diagnosis If we regarded the mandibular tumor as a primary carcinoma, there was a possibility to operate uncurable tumor. This case implies the necessity of thorough general evaluation of the patient before the malignant tumor surgery in maxillofacial area

권대우 홍익대학교 법학연구소 2003 법학연구 Vol.5 No.-

Die beide Lander haben Sondergesetze uber die Produkthaftungen. Die Tatbestande sind aber nicht identisch. 1. Haftungstragersind Hersteller, Quasi-Hersteller, Importeur, Lieferant sowohl in Korea als auch in Deutschland. Die Frist der Bennenung des Herstellers ist eine angemessene Frist nach dem koreanischem Produckftungsgesetz, anders als eine Monatsfrist nach dem deutschem Recht. Und das Gesetz Verlangt noch andere Tatbestand furdie Lieferanthaftung. die Erkenntnis oder Fahrlassigkeit des Lieferants uberden Hersteller. 2. Fehlerbegriffe nach dem koreanischen Sondergesetz sind nicht identisch mit denen nach dem deutschem Recht. Wahrend Deutschland den Begriff sehr abstrakt geregelthat, regelt das koreanische Soundergesetz relativ konkret Fabrikationsfehler, Konstruktionsfehler. Instruktionsfehler und Produkt ohne allgemein erwartete Sicherheit. Das Gesetz verlangt die Ersetzbarkeit mit noch sicheren Design fur Konstruktionsfehler ausdr?cklich. Produktbeobachtungpflicht sind ausdr?cklich geregelt Nach dem koreanischen Recht sind die Problome mit den Arzneimittln niclt getrennt behandelt. sondern als Produktshaftung gleich geregelt. 3. Entlastungsmσglichkeit fur Produzent sind nach dem koreanischen Recht noch umfangerich geregelt. Daher beschrankende Auslegung ist erforderlich Entlasuntung durch Regelhalten verlangt nach dem gesetzestext keine zwingende Charakter. 4. Nach dem koreanischen Sondergesetz regelt keine Sdlbstbeteiligung und keinen haftugshochstbetrag

Self-Esteem Development as A Hidden Curriculum Effect of Adult Vocational Microcomputer Education

權大鳳 고려대학교 교육문제연구소 1991 敎育問題硏究 Vol.4 No.-

1890년에 心理學者인 윌리암 제임즈가 自矜心에 관한 硏究를 시작한 이래 지난 100년동안 자긍심에 관한 수많은 硏究結果가 發表되었다. 수 많은 연구논문의 共通된 發見중의 하나는 자긍심이 우리 인간의 社會生活 특히 成功的인 職場生活을 위해 꼭 必要하다는 것이었다. 실제로 기업,정부, 단체 및 학교기관은 자긍심개발을 硏修科目으로 운영하고 있는 실정이다. 이제까지의 자긍심에 관한 연구는 거의 모두가 心理的인 혹은 社會學的인 側面에서 探究된 것이었고 敎育學的인 측면에서 硏究된것은 극히 소수에 불과하였으며, 성인 컴퓨터 직업교육의 틀에서 연구된 것은 전혀 없었다. 現代의 하이테크/하이터치 사회에서 성공하려면 누구나 컴퓨터를 사용할줄 알아아야 하며 직장인에게는 거의 必須的이다. 그러나 일부학자들은 성인이 컴퓨터를 배우고 사용하게되면 非人間化될 우려가 있다고 주장하였다. 한편 潛在的 敎育課程效果를 연구해온 학자들은 그 肯定的 效果보다는 否定的 效果를 ????시켜 왔다. 本 硏究에서 연구자는 「성인이 성인교육방법에 의하여 컴퓨터 직업교육을 받으면 그 잠재적 교육과정의 긍정적 효과로서 교육참가자의 自矜心이 發達될 것이다」라는 假說을 세우고 敎育學的인 立場에서 연구를 하였다. 연구대상은 미국 미시간주의 産業協同 프로그램에 參加한 성인 120명(남 27,여93)이 었고, 6개월간의 컴퓨터교육을 받기 前과 敎育直後에 2회에 걸쳐 標準化된 自矜心 檢査를 실시하여 그 變化를 測定하였다. 가설 검증의 量的인 分析을 위해 有意水準 p<.5에서 從屬표집에서의 t 테스트,多變量分析,그리고 重回歸分析을 하였고,質的資料의 補完을 위해 現場 訪問,觀察 및 인터뷰를 실시하였다. 量的分析結果 成人이 컴퓨터 職業敎育을 成人敎育方法에 의하여 敎育받으면 그 潛在的 敎育課程의 肯定的 效果로서 自矜心이 發達된 것으로 假說이 檢證되었고 質的인 資料도 이를 뒷받침해주었다. 敎育參加者중 직업이 없는 사람이 職業이 있는 사람보다 자긍심이 더 높은 水準으로 발달한 것으로 나타났는데 이것은 직업이 없는 사람이 교육중 社會化를 經驗하고, 교육후 就業할 수 있게 되어 자긍심이 발달된 것으로 解釋할 수 있다. 교육참가자의 성별,인종, 나이 ,교육정도,학교위치,오전오후 저녁 수업시간대, 컴퓨터 사용 경험, 결혼상태에 따른 자긍심 발달의 의미있는 差異는 발견되지 않았다. 양적 및 질적 분석 결과에 의하면 교육참가자의 자긍심 발달에 가장 影響을 끼친 것은 成人敎授法으로 나타났고, 그 다음 요인으로는 컴퓨터 프로그램 사용 技能獲得이었다. 또한 社務室처럼 꾸며진 敎室 環境과 經歷開發을 도우는 서비스 역시 자긍심 발달에 영향을 준 것으로 나타났다. 연구자는 본 연구의 결과를 토대로 성인을 위한 컴퓨터직업교육시 成人敎育環境條件을 具備하고 成人敎育方法을 이용한다면 肯定的인 潛在的敎育課程 效果로서 自矜心이 發達된다는 모델을 提示하였다
