The aim of the present study was to investigate the efficacy of a mixed gel formulation composed of sodium carboxymethyl cellulose and gellan gum (Na-CMC gel) for the prevention of adhesions after laminectomv. The anti-adhesive effect of the Na-CMC gel was tested in a controlled randomized study using an animal model of lumbar laminectomv. The animals (60 female Sprague-Dawlev rats) were randomly allocated into two treatment groups to receive the Na-CMC gel on the injured area or no gel (control). The incidence of adhesions and their grade were blindly evaluated at 4. 8 and 12 weeks after surgery. The amount of scar tissue and tenacity were grossly reduced by the Na-CMC gel at postoperative 4. 8. and 12 weeks. The mean adhesion scores were 0.75. 125. and 1.38 at 4. 8. and 12 weeks in the gel-treated group. respectively. No significant inflammatory reaction was observed and the healing of wound was not affected by the Na-CMC gel. The Na-CMC gel reduced the amount of scar formation and tenacity in rat laminectomv model without affecting the healing of operation wound and other complications. Therefore. the Na-CMC gel may be the potential to prevent postsurgical adhesions in clinical state.

Background : Atherosclerosis is the chief underlying cause of ischemic heart disease and there is increasing evidence that inflammation is an important determinant of the development of atherosclerosis. We assessed the levels of inflammatory markers in patients with ischemic heart disease and normal group who has normal coronary angiograms. Materials and Methods : Coronary angiography was performed in 142 patients. 107 patients of ischemic heart disease(stable angina pectoris 58, unstable angina pectoris 30, Acute myocardial infarction 19) and 38 normal control subjects. We assessed the level of inflammatory markers, such as CRP, ESR, fibrinogen and leukocyte. Results : CRP, ESR and fibrinogen values of the patients with stable angina pectoris and unstable angina pectoris were higher than that of normal control group, but there were no statistical significance. Leukocyte value of the patients with unstable angina pectoris(9003.3±701.5/mm^(3)) was significantly higher than that of the patients with stable angina pectoris(6685.5±245.8/mm^(3)) and normal control subjects(6394.3±235.1/mm^(3)). CRP, ESR and fibrinogen values of the patients with acute myocardial infarction were also higher than that of normal control subjects. CRP was 3.88±2.05 mg/dL in acute mocardial infarction group, and 0.29±0.15 mg/dL in normal control subject group(p<0.05). Fibrinogen was 541.6±45.1 mg/dL in acute myocardial infarction group, 321.4±25.6 mg/dL in normal control subject group(p<0.05). Leukocyte was 10942.1±737.6/mm^(3) in acute myocardial infarction group, 6394.3±235.1/mm^(3) in normal control subject group(p<0.05). Conclusions : This study demonstrate that CRP, fibrinogen and leukocyte values of acute myocardial infarction group were significantly higher than that of control group and stable, unstable argina pectoris group. Leucokyte values were significantly elevated in unstable angina group, but CRP values were not in unstable angina group.

Non-destructive instrumented indentation is proposed as a promising alternative of the conventional stress-measuring methods based on already-reported its sensitivity to applied stresses. In this study, we tried to expand the current indentation model on equi-biaxial stress to the characterization of general surface stress in nonequi-biaxial state. A contribution of the surface stress on indentation plasticity was theoretically extracted from the non-equi-biaxial stress matrix. And, a newly derived stress equation was expressed as a multiple of stress non-equibiaxiality and residual-stress-induced normal load. An experimental tests for confirming the model were also conducted on artificially strained API X65 steel plate, and produced the non-equi-biaxiality factor consistent with that from theoretical analysis.

본 연구는 예비유아교사의 음악적 자아개념 및 음악적 개념에 대한 실제이해와 음악교수 효능감의 수준을 알아보고, 이들 간의 관련성과 영향력을 살펴보는 데에 목적이 있다. 연구 대상은 경상남도에 위치한 3, 4년제 대학의 유아교육과 학생 201명이었으며, 연구 도구는 Svengalis(1978)가 개발하고 Philips(2002)가 수정한 ‘음악적 자아개념 척도’, Kim, Lee, Kwon과 Park(2011)이 개발한 '유아교사의 음악적 개념 실제이해 측정 도구’, Riggs와 Enochs(1990)가 개발하고 방은영, 박찬옥(2005)이 수정한 ‘음악교수 효능감 검사도구’가 사용되었다. 연구결과를 살펴보면 첫째, 예비유아교사의 음악적 자아개 념과 음악적 개념에 대한 실제이해는 보통 수준인 것으로 나타났으며, 음악교수 효능감은 비교적 높은 것으로 나타났다. 둘째, 예비유아교사의 음악적 자아개념, 음악적 개념에 대한 실제이해, 음악교수 효능 감은 대체로 유의한 정적 상관을 보였다. 셋째, 예비유아교사의 음악적 자아개념과 음악적 개념에 대한 실제이해는 예비유아교사의 음악교수 효능감 전체에 영향력을 미치고 있었으며, 하위요인 중 음악교수 능력에 대한 신념은 예비유아교사의 음악적 자아개념이 더 큰 영향력을 미쳤고, 결과에 대한 기대감은 음악적 개념에 대한 실제이해만이 영향력 있는 요인으로 나타났다. This study aimed to (1) examine early childhood pre-service teachers’ self-concept in music, the actual level of understanding of musical content knowledge and music teaching efficacy, and (2) investigate the relationships and influence among them. The participants consisted of 201 undergraduate students, majoring in early childhood education at colleges in Gyeongnam, Korea. The measurements used in this study were Self-Concept in Music Scale (SCIM), the scale of Understanding of Musical Content Knowledge, and Music Teaching Efficacy Belief Instrument (MTEBI). The results of this study are as follows. First, the mean score of early childhood pre-service teachers’ self-concept in Music and actual understanding of musical content knowledge were about the average, besides their music teaching efficacy was higher than the average. Second, there was a positive relationship among early childhood pre-service teachers’ self-concept in music and music teaching efficacy, and the actual level of understanding of musical content knowledge. Third, early childhood pre-service teachers’ music teaching efficacy exerted a statistically significant influence on the self-concept in music and the actual level of understanding of musical content knowledge. Among the variables of early childhood pre-service teachers’ music teaching efficacy, 'the belief of music teaching ability' and 'the expectation of the results', pre-service teachers’ self-concept in music had more influence on 'the beliefs of music teaching ability' and actual understanding of musical content knowledge was the only influential factor on 'the expectation of the results'.

Background and aims : In the coronary artery disease, a rate of restenosis was much decreased by placement of coronary stent than when percutaneous transluminal coronary angioplasty has been applied, but there are still important clinical problems of restenosis. There has been many progressive studies about various factors contributed to this restenosis. So, we studied a relation between restenosis after placement of coronary stent in the coronary artery disease and many clinical factors, characteristics of stenotic lesion and procedural factors, and also assessed the restenosis rate of various coronary stents. Methods : Total 58 lesions(46 cases of patients ; man 30, woman 16) were evaluated, which has been performed a follow-up coronary angiography after 6 months (mean 188 days) since coronary stent had been placed. Various stents were implanted and assessed a relation between restenosis and many factors. Results : Of 58 lesions were target stenotic studies, there were 22 of restenotic lesions(37.9%), and the restenosis rate wes statistically significant difference in the relation with diabetes mellitus(p<0.05), group of acute myocardial infarction(p<0.05) among clinical diagnosis of ischemic heart disease(stable angina, unstable angina and acute myocardial infarction) in clinical factors and with high dilation pressure of stent(p<0.05) in procedural factors. When the rate of restenosis was evaluated among implanted stents, it was lowest in the Multilink^(®) stent and highest in the Nir Royal^(®) stent(60%). Conclusion : In this study of restenosis and various factors after placement of stents in the coronary artety disease, factors such as diabetes mellitus, group of acute myocardial infarction and a dilation pressure of stent were significant related with restenosis and the restenosis rate of Multilink^(®) stent was lowest and the highest restenosis rate was of Nir Royal^(®) stent.

최병순,한효순,강성주,이상권,강순희,박종윤,남정희 한국과학교육학회 2002 한국과학교육학회지 Vol.22 No.4

학생들의 인지발달을 촉진시켜 학습효과를 높이려고 개발된 CASE 프로그램의 효과를 조사했다. 중학교 1학년(841명) 학생들이 연구에 참가하였으며, 같은 분량의 시간동안 실험반에서는 교육과정에 따른 과학 교과 수업과 '생각하는 과학' 활동을 병행하였고, 통제반에서는 과학교과 수업만을 수행하였다. 연구 초기에 논리적 사고력 검사(SRT II)를 이용하여 집단의 동질성을 비교하고, 2년 동안 실험반에 CASE프로그램을 처치한 후 이질동형겸사도구인 SRT VII을 이용하여 처치별, 성별, 인지수준별 인지가속에 대한 효과를 조사했다. CASE 프로그램에 의한 중학생들의 인지발달 가속효과는 중간검사에서는 보이지 않았으나, 사후검사에서 상당히 큰 것으로 확인되었다. 성별에 따라 CASE 프로그램의 효과를 비교한 결과 남??여 중학생들 모두에게 유의미한 인지가속이 이루어진 것으로 나타났다. 남학생들 보다 여학생들의 인지수준이 더 발달된 것으로 밝혀졌으며, 처치와 성별간 상호작용 효과는 나타나지 않았다. 학생들의 사전 인지수준에 따라 CASE 프로그램의 효과를 분석한 결과, 모든 인지수준에서 처치효과가 뚜렷하게 있었으나 특별한 경향성은 나타나지 않았다. 특히 초기 구체적 조작기(ES=1.1.)와 전조작기(ES=1.07), 그리고 구체적조작 후기(ES=1.01) 학생들에게 상당히 큰 효과가 있었다. 이상과 같은 CASE 프로그램의 성공적인 결과는 현행 우리나라 과학교육과정 개정과 교수방법 개선에 시사하는 바가 많다. In an attempt to accelerate the development of formal reasoning ability of students, 'Thinking Science' activities developed by the Cognitive Acceleration through Science Education(CASE) project were implemented to 841 students in 7th grade aged 12+ in six middle schools over a period of two years. Homogeneity between the CASE group and control group was tested with SRT Ⅱ, while the improvement of formal reasoning ability of the students was tested with SRT Ⅶ. The results were analyzed by treatment, gender, and cognitive levels of the students. Statistically significant gains were shown in the CASE group compared with those in the control group. Cognitive level of girls in the CASE group significantly increased as compared with the control group, while there was moderate effect in boys. These results implied that the thinking science activities were effective in cognitive acceleration of girls aged 12+. It was shown that much more CASE students in pre or concrete operational level shifted. to formal operational level as compared with the control group while there were significant effects in all levels (ES=0.31∼1.10) without showing any tendency.
