The subjects of this study were 231 elementary pre-service teachers. The relationship between elementary pre-service teacher’s music subject self-efficacy and previous experience about music education was investigated using Pearson product-moment correlation coefficient. There was a medium correlation between the two variables, r =.36, n =189, p < .0005.

초등학생들의 인성 및 도덕성 향상을 위한 창작동요 지도방안 연구

윤관기 한국음악교육학회 2018 음악교육연구 Vol.47 No.4

본 연구는 초등학생들의 인성 및 도덕성 향상을 위해 창작동요를 활용한 수업지도 방안을 마련하는데 있다. 음악은 예로부터 정서함양은 물론 윤리적 행동 변화를 유발할 수 있는 도구로서 그 효과를 검증해 왔으며, 음악양식뿐만 아니라 음악 가사 또한 공동체 속에서 도덕성 발달에 관여한다고 볼 수 있다. 그 일환으로 동요를 활용한 아동의 개도는 지속적으로 이루어져 왔으며, 그 중에서 창작동요는 그 개발과 함께 많은 의도를 지니고 불려 왔다. 무엇보다 창작동요는 교육적 가치를 포함하고 있다는 점에서 ‘계몽동요’ 라고 불리기도 하며, 우리 사회에서 가르치고자 하는 도덕적 또는 윤리적 내용을 내포하고 있어 어린이들의 인격 형성을 목적으로 하고 있다. 이러한 창작동요의 가치를 이해하고 그 가사가 지니고 있는 의미를 파악하는 한편, 음악수업에서 통합적 교수 학습 모형을 적용하여 창작동요를 지도한다면 아이들의 인성 및 도덕성을 충분히 함양할 수 있을 것이다.

尹寬基,尹承鎬 충남대학교 의과대학 지역사회의학연구소 1985 충남의대잡지 Vol.12 No.1

Many studies have been conducted on the toxicity of methylmethacrylate monomer. Methylmethacrylate monomer has been known to cause physiological and histological changes in various organ systems. Particularly well-known are its effect on the vascular system and blood pressure. However, pharmacological effect of the monomer on the cardiac muscle, especially its direct action on the contractility and excitability, and on acid-base balance has not been clarified. In the present study, pharmacological effect of the monomer on the cardiac function was investigated through the measurement of contraction forces, maximal dT/dt and latency with Physiograph and its accessories in the turtle heart perfused with turtle Ringer solution containing the monomer liquid. Acid-base parameters, respiration, blood pressure and heart rate were measured with Physiograph in rabbits after intravenous injection and during continuous infusion of the monomer. Arterial blood was sampled in an anaerobic condition and analyzed with a blood gas analyzer. The results obtained are summarized as follows. 1. The contraction forces, maximal contraction dT/dt, maximal relaxation dT/dt were reduced markedly by methylmethacrylate monomer. 2. The latency was prolonged remarkably by methylmethacrylate monomer. 3. The heart rate was reduced markedly by methylmethacrylate monomer. 4. The tidal volume of respiration was reduced but the respiratory rate was increased significantly by the intravenous injection of methylmethacrylate monomer. 5. The tidal volume of respiration was increased but the respiratory rate was not changed by the intravenous infusion of methylmethacrylate monomer. 6. The arterial pH, PO_2 and base deficit were increased but PCO_2 and bicarbonate concentration were decreased by both intravenous injection and infusion of methylmethacrylate monomer. From the above results, it was concluded that methylmethacrylate monomer depresses the cardiac contractility and excitability and causes the respiratory alkalosis through enhanced ventilation.

윤관기 한국음악교육학회 2014 음악교육연구 Vol.43 No.1

The purpose of this study is to survey pre-service elementary teachers’ perception and satisfaction about the instructor’s feedback in pedagogy of music subject. A total of 407 pre-service elementary teachers participated in this study, and their perception was obtained through questionnaire. The results from the study are as follows: First, 82% of pre-service elementary teachers answered that the instructor’s feedback is necessary for developing teaching-learning process plans and understanding the pedagogy of music subject. Second, nearly 70% of pre-service elementary teachers preferred the reserved feedback. It means that they would like to have a chance to modify their mistakes before instructor gives right/wrong answers immediately. Third, 72% of pre-service elementary teachers would prefer receiving the instructor’s feedback after the teaching practice rather than receiving the instructor’s feedback during the teaching practice. Lastly, the instructor’s feedback contributed to fostering academic achievement toward music subject and to understanding the practice teaching in pedagogy of music subject.

관절활액 분석에 의한 만성슬관절염의 진단에 관한 임상적 연구

윤관기 충남대학교 의과대학 지역사회의학연구소 1981 충남의대잡지 Vol.8 No.2

The swelling of arthritic joints due to fluid accumulation is the major pathologic changes in several arthritis conditions of knee. The synovial fluid analysis was performed from selected 77 patients of chronic arthritis of knee who registered or admitted to Chungnam National University Hospital during the 11 months from October 1980 to September 1981. And the synovial fluid were aseptically collected for studies. Following are the summary of the study: 1. Among 77 cases, 30 were diagnosed as degenerative arthritis, 25 as rheumatoid arthritis, 8 as non-specific synovitis, 8 as traumatic arthritis, 2 as tuberculous arthritis, and 4 as pyogenic arthritis. 2. By routine synovial fluid analysis, the patients with degenerative & traumatic arthritis were classified into the group of noninflammatory fluid and the patients with rheumatoid arthritis were classified into the inflammatory fluid group and the patients with tuberculous & pyogenic arthritis were classified into the group of infectious fluid. 3. In the age and sex distribution, there was not a specific difference, but degenerative arthritis of knee was noticed only over the 40 years old. 4. All cases of degenerative arthritis showed transparent yellow color, but cases of rheumatoid arthritis of knee revelaed transparent or turbid yellow or greenish color. 5. High viscosity was noticed in all cases of degenerative arthritis. Low viscosity was noticed in 19 cases (76%) of rheumatoid arthritis (25 cases). 6. Good mucin clot was shown in all cases of degenerative arthritis of knee. Poor mucin clot was revealed in 17 cases (67%) of rheumatoid arthritis. 7. W.B.C. was less than 2,000 cells/㎣ in 27 cases (93%) of degenerative arthritis. But in cases (44%) of rheumatoid arthrits, W.B.C. was 2,000-15,000 cells/㎣. In diffdrential count of W.B.C., ploymorphonuclear leukocyte was less than 25% in 19 cases (63%) of degenerative arthritis, but that was 25 to 75% in 13 cases(52%) of rheumatoid arthritis. 8. Glucose was more than 81mg% in 26 cases (87%) of degenerative arthritis and in 23 cases (29%) of rheumatoid arthritis, but in tuberculous and pyogenic arthritis that was less than 80mg%. 9. Mean total protein amount was 3.3mg% in degenerative arthritis. In the others, that was increased. i. e., in rheumatoid arthritis (3.7mg%) in traumatic arthritis (3.5mg%) and in tuberculous and pyogenic arthritis (4.4mg%, 4.6mg%, respectively). Although these results of synovial fluid analysis could not give the conclusive & definite aid in differential diagnosis of chronic arthritis of knee, it was considered that they have only the value of an anxillary role in differential diagnosis associated with their specific symptoms of each type of arthritis.

본 논문에서는 1Gbit 이상의 반도체 메모리 제조공정에 적용할 수 있는 Cu Damascene 공정을 연구하였다. 제반단위공정으로써 E-beam lithography, SiO_2 CVD, RIE 및 Ti/Cu CVD 등을 연구하였으며, 각 단위공정을 이용하여 2층의 Cu 금속배선을 제작하였다. CMP 단위공정 연구결과, head압력 4 PSI, table 및 head 속도 25rpm, 진동폭 40mm, 슬러리 공급량 40㎖/min에서 연마율 4,635Å/min, Cu:SiO_2의 선택율 150:1, 평탄도 4.0%를 얻었다. E-beam 및 SiO_2 via-line 공정연구 결과, 1000μC/㎠의 도즈와 6분 30초의 현상 및 1분 10초의 에칭시간으로 0.08㎛ Cu Damascene 패턴을 형성하였다. 또한, Cu void 및 Cu의 peeling으로 인한 다층공정시의 문제점과 재현성 향상을 위한 방법을 제시하였다. Core processes for 1Gbit memory devices such as Cu damascene process using CMP, Electron beam lithography, SiO_2 CVD and RIE and Ti/Cu-CVD were carried out and then, two level Cu interconnects were fabricated. In the results of CMP process, a 4,635Å/min of removal rate, a selectivity of Cu : SiO_2 of 150:1 and uniformity of 4.0% are obtained under process conditions of a head pressure of 4 PSI, table and head speed of 25rpm, a oscillation distance of 40mm, and a slurry flow rate of 40㎖/min. Also 0.18㎛ SiO_2 Via-line patterns are fabricated using 1000μC/㎠ dose, 6min and 30sec development time and 1min and 30sec etching time. And finally 0.18㎛ Cu Damascene patterns using the developed processes were fabricated and, then, problems of multilevel interconnects, for example, Cu void and Cu peeling are discussed.
