高永春 中央醫學社 1965 中央醫學 Vol.8 No.3

Twenty one cases of otitic intracranial complication were observed in the dept, of Otolaryngology, Chonnam University Hospital from 1960 to 1964. In order of their relative frequency of incidence, these complications were: 1) lateral sinus thrombophlebitis 2) meningitis 3) epidural abscess 4) brain abscess 5) subdural abscess Of these twenty one cases, only four cases of lateral sinus thrombophlebitis and two cases of epidural abscess occurred independently without having other complication, while the rest of the cases revealed combination of more than two complications. All of twenty one cases followed after having chronic suppurative otitis media but none of them from acute otitis media. In nineteen cases out of twenty one cases (approximately 90%), cholesteatoma was found in mastoid antrum or attic. In all cases, bony destruction was demonstrated in the lateral sinus plate, tegmen antri or tegmen tympani. Of sixteen cases for which bacterial culture was carried out, eleven eases revealed gram negative bacillus such as proteus, paracolon and escherichia. And the other three cases showed gram positive coccus mixed with gram negative bacillus. Four cases of brain abscess were dead, while the rest of the cases were cured without any sequel.

Statistics by structural equation modeling techniques were used to assess a model of chemistry learning strategy based on performance goal orientation. In the optimal Model III of this research, Performance-approach goal was positively related to the use of learning strategy(p<.05) and achievement need(p<.05). Performance-avoidance goal was negatively related to learning strategy(p<.05) and was positively related to self-handicapping tendency(p<.15). Performance-approach goal affected learning strategy indirectly through achievement need(p<.05). Use of achievement need was positively related to learning strategy(p<.05) and self-handicapping tendency(p<.35). Self-handicapping tendency affected learning strategy negatively(p<.05). Implications of these findings for learning strategy in chemistry education are discussed.

염화나트륨 수용액에서 비스(1,10-페난트롤린)구리(II) : 도데실황산나트륨 용액의 전기화학적 거동

고영춘 대불대학교 1998 論文集 Vol.4 No.1

Electerochemical behaviors of 1,0 mM bis(1,10-phenanthroline)copper(Ⅱ)(Cu(ph)_(2)^(2+)) in 100 mM NaCl solution, without and with sodium dodecyl sulfate(SDS), were investigated. In the presence of SDS, E_(pa) and E_(1/2) of Cu(ph)_(2)^(2+/+) shift to the negative direction compared to the SDS free. The intersection of two lines on ΔE_(p) vs. -log[SDS] was determined as a critial micelle concentraction (CMC).

Laminar flow within large vessels or organs can cause artifact that may simulate thrombus during computed tomographic study. The degree of venous enhancement depends on the size of blood pool and cardiac output in relation to the time of scanning. When venous structures are scanned too fast after injection of contrast material, poor mixing of enhanced and unenhanced blood creates flow artifact that gives an appearance of deep venous thrombosis. As compared with dynamic computed tomography (CT), because of a shorter acquisition time of spiral CT, vascular and organ enhancement on spiral CT scan are more dependent on factor that affect delivery of contrast material into the blood stream. Differentiation from true thrombus can be made by use of delayed scan as well as increased density and finding of relatively poor margination of artifact. In addition, both angiography and echocardiography could complement CT to assure that false-positive results are minimized. We experienced a case of artifact mistaken for intracardiac mass on spiral CT, but it was not noted on echocardiography. 저자들은 컴퓨터 단층촬영상 우심방과 상대정맥내 종양으로 진단되었으나 심초음파상 이러한 병변이 발견되지 않은 수축성 심낭염 1례를 경험하였기에 문헌고찰과 함께 보고하는 바이다.

Voltammetric Study of Anionic Surfactant-Modified Glassy Carbon Electrode for Bis(2,2'-Bipyridyl)Copper(II) in 200 mM NaBr

고영춘 조선대학교 기초과학연구원 2014 조선자연과학논문집 Vol.7 No.2

When a hydrophobic and hydrophilic environments of bis(2,2'-bipyridyl) copper(II) (Cu(bpy)2 2+) are produced in the presence of anionic surfactant sodium dodecyl sulfate (SDS), cyclic voltammetry is used to investigate the microscopic environments which occurs at the glassy carbon electrode. In order to see the relation between ΔEp and a critical micelle concentration (CMC), ΔEp vs. -Log[SDS] for the redox couples are plotted. The concentration at the intersection of twolines is 2.57 mM SDS, and this concentration can be determined as the CMC (relative error: below 0.03%; 2.63 mMSDS by surface tensiometry).

Structural equation modeling techniques were used to assess a model of science learning strategy (or self-handicapping tendency) based on goal orientation. Data were collected during science lessons from two middle schools. In the optimal model Ⅱ-2 of this research, the learning goal was positively related to the use of self-efficacy, achievement need, and learning strategy. The performance-approach goal was positively related to self-efficacy and achievement need. The performance-avoidance goal was negatively related to self-efficacy but presented a positive relationship to self-handicapping tendency and entity theory of intelligence. The achievement need was positively related to self-efficacy. The entity theory was negatively related to achievement need but represented a positive relationship to self-handicapping tendency. The self-efficacy was positively related to learning strategy Aside from indirectly affecting the learning strategy through self-efficacy. the learning goal directly affected the learning strategy. The performance-avoidance goal affected the learning strategy directly but was indirectly affected through the entity theory. The learning goal, performance-approach goal, and achievement need were positive predictors of self-efficacy, but the performance-avoidance goal was a negative predictor. The learning goal and performanceapproach goal were positive predictors of achievement need, but the entity theory was a negative predictor. The performance-avoidance goal was a negative predictor of entity theory. The learning goal and self-efficacy were positive predictors of learning strategy. The performance-avoidance goal and entity theory were positive predictors of self-handicapping tendency. The implications of these findings for learning strategy or self-handicapping tendency in science are discussed. Although the structural equation model of causal relationships of the motivations to learn and learning strategies in science education are established as mentioned above, a more systematic study to improve learning strategies and to lower self-handicapping tendency in different courses may be needed. 본 연구에서는 학습전략 또는 자기핸디캡경향에 미치는 관련변인들의 인과관계를 탐색하기 위해 각 관계된 변인들 간의 경로모형을 연구모형 I과 연구모형 II의 기본모형으로 설정했다. 이 연구모형의 관점에서 과학교과를 대상으로 체계적이고 정밀한 분석을 통해 학습전략 또는 자기핸디캡 경향에 미치는 관련변인들의 인과관계를 살펴보았다. 그 결과 연구모형 I과 연구모형 II 중에서 연구모형 II가 채택되었고 이 모형의 주요한 통계적 적합도 지수들을 확인하여 분석하면서 경로를 추가했고 1차 수정한 결과, 연구모형 II-1의 구조방정식모형이 본 연구의 완전모형으로 선택되었으나, 이 모형을 분석한 결과, 유의수준 p≤.05의 경계값인 |±1.96| 보다 작은 값인 12개의 경로들이 제거됨으로써 연구모형 II-2의 구조방정식모형이 본 연구에서 최종적인 최적 연구모형으로 채택되었다. 즉 목표지향성의 변인이 ‘자기효능감, 성취욕구 및 지능신념’의 변인을 매개로 하여 ‘학습전략 혹은 자기핸디캡경향’으로 향하는 연구모형 II-2의 구조방정식모형이 본 연구에서 최종적인 최적 연구모형으로 채택되었다. 이 채택된 모형은 숙달목표, 수행접근목표 및 성취욕구가 자기효능감에 정적인 효과를 주었으나 수행회피목표는 자기효능감에 부적인 영향을 주었고, 숙달목표와 자기효능감은 학습전략에 정적인 영향을 주었다. 또한 수행회피목표와 지능신념이 자기핸디캡경향에 정적인 영향을 주었다. 아울러 학습전략은 ‘숙달목표, 수행접근목표, 수행회피목표, 지능신념과 성취욕구’의 변인에 의해 간접적으로 영향을 받은 자기효능감 및 직접적인 숙달목표에 의해 영향을 받았고, 자기핸디캡 경향은 수행회피목표의 변인에 의해 간접적으로 영향을 받은 지능신념 및 직접적인 수행회피목표에 의해 영향을 받고 있음을 알았다.

Electrochemistry of 1.0 mM bis(1,10-phenanthroline)copper(II) (Cu(ph)22+) in 100 mM NaCl solution2 with and without sodium dodecyl sulfate (SDS) is studied. In the presence of SDS,Epa and E1/2 of Cu(ph)22+ by adding Mg2+ shifts to a positive direction compared to the SDS free. The intersectionof two lines on Ep vs -log[SDS] plot is determined as a critical micele concentration (CMC). When Mg2+is added, it seems that the double layer became more compact.
