      • 단위제 실시에 관한 문제점 조사연구 : 제주도 인문계 고등학교를 중심으로 on the humane high schools in Jeju-Do

        한철순,현종익 제주대학 1980 논문집 Vol.12 No.2

        Our educational courses and curriculum have frequently due to frequent changes in the educational environment. In the highshools, the unit system was adopted on Feb, 15th, 1963. Yet the current school teachers have a poor understanding and knowledge of it. Therefore, this system can't be run effectively. The current school teachers undertake many difficulties by accepting responsibilities for school affairs. There is a pressing need to increase their knowledge of the unit system. The salient point of the unit system is that in principle every high school should adopt the unit system. Under our actual education circumstances, it is very hard to adopt the complete unit system. However, in order to promote uniform education and to have chance to take one's adoptability by opticonal course, we should have deep knowledge of it. The unit system prescribes as follows; 1) In principle, the high school teaching curriculum should adopt the unit system. However, due to difficulties adopting the unit system, they can adopt the grade system, or both the grade system and the unit system. 2) The unit allotment table shows the total unit numbers which the 3rd grade high school students need to complete the regular course. 3) Usually we have 36 weeks of school-days per year. One unit means to complete the regular course for 18 unit hours per term, and 1 unit hour has 50 minutes. 4) According to student's career and job selection, high school courses can be dclassified into humanistic, scientific, vocational and art courses. 5) with respect to the weather, season and the characteristic of the subject contents, they can make an available unit-hour education curriculum. But since most of the current school teachers have a poor knowledge on the principles of the unit system, the aim of this paper is to help them understand the necessity of the unit system and to offer them information necessary to restructure the education curriculum. In conclusion this paper describes the actual circumstances and problems of high schools, and attempts to improve them

      • 심실중격결손증-치험 1예-

        조광현,우종수,황윤호,이양행,박철호,김종성,김철호,이경순,조영일,박태인 인제대학교 1985 仁濟醫學 Vol.6 No.4

        A successful treatment of infants and children with congenital heart defects depends upon several factors: diagnosis must be accurate, the operative technique, including techniques of perfusion and myocardial preservation, must be suited to the needs of patients and intensive cares, including accurate anesthesia, must be applied through all stages of investigation and treatment, i.e. before, during and after the operation. Recently we performed a open heart surgery successfully for a six-years old girl who had suffered from frequent upper respiratory tract infection and mild to moderate exertional dyspnea with congenital heart defects (ventricular septal defect, Kirklin type II, with patent foramen ovale). The operation and postoperative course were very smooth. And now we report this with review of literatures.

      • 혈청 Fructosamine에 대한 임상적 유용성에 관한 연구

        김철,김용태,노상현,홍순표,김미송,장숙진,박희완,문대수 朝鮮大學校 附設 醫學硏究所 1991 The Medical Journal of Chosun University Vol.16 No.1

        Diabetes mellitus is a universal health problem and may occur at any age. The traditional biochemical measurements for initially detection patients with diabetes mellitus are random estimations of blood and urine glucose concentrations. Despite their common use both tests are fairly non-specific, being influenced by wide variety of condition. Measurement of the HbA_(1c) in a random blood specimen is a more simple screening test for diabetes, and widely used as an index of diabetic control. But unfortunately, it has difficulties with methodology. Fructosamine has been described as a new parameter for the estimation of glycosylated protein, It is based on the reduction potential of ketoamines in an alkaline medium and measures colorimethcally the concentration of all glycosylated semm proteins belonging to the class of fructosamine. It reflects the time-integrated glucose concentration over the previous 1 to 3 weeks and can be used for the follow up of diabetes mellitus. We measured serum fructosamine concentration and compared with any other items. The results are summehzed as follows : 1. Within-run and between-run imprecision were assessed by 20 analysis of 3 differential fructosamine concentration in control sera. The respective coefficients of variation were 2.9%, 6.6% in low concentration, 2.2%, 5.1% in medium concentration and 3.3%, 4.7% in high concentration. 2. The serum fructosamine concentration were 2.26±0.21 mmol/L in normal control subjects(n=29) and 3.35±0.65 mmol/L (n=62) in patients with diabetes mellitus (p<0.001). 3. In diabetic patients (n=62), the serum fructosamine concentrations correlated less significantly with glucose (Y(fructosamine) = 0.01×(glucose)+2.52, r=0.54, P<0.001) and more significantly with HbA_(1c) (Y(fructosamine) = 0.22×(HbA_(1c))+1.71 , r=0.63, P<0.001). 4. The concentrations of fructosamine in serum and EDTA plasma were not significently diferent (P<0.01). So, Plasma is as well suited to fructosamine determinations as serum(Y(serum) = 0.95×(Plasma)+0.25, r=0.96). 5. No interference was observed with lipemic sera (cholesterol) in detection of serum fructosamine(P=0.393).

        김현우,허경회,박관수,김정화,이원진,허민석,이삼선,최순철 대한구강악안면방사선학회 2006 Imaging Science in Dentistry Vol.37 No.1

        Purpose : To investigate the validity of digital image processing on panoramic radiographs in estimating bone quality before endosseous dental implant installation by correlating bone quality in radiographic images with clinical bone quality classification. Materials and Methods : An experienced surgeon assessed and classified bone quality for implant sites with tactile sensation at the time of implant placement. Including fractal dimension eighteen morphologic features of trabecular pattern were examined in each anatomical sites on panoramic radiographs. Finally bone quality of 67 implant sites were evaluated in 42 patients. Results : Pearson correlation analysis showed that three morphologic parameters had weak linear negative correlation with clinical bone quality classification showing correlation coefficients of -0.276, -0.280, and -0.289, respectively (p<0.05). And other three morphologic parameters had obvious linear negative correlation with clinical bone quality classification showing correlation coefficients of -0.346, -0.488, and -0.343 respectively (p<0.05). Fractal dimension also had a linear correlation with clinical bone quality classification with correlation coefficients -0.506 significantly (p<0.05). Conclusion : This study suggests that fractal and morphometric analysis using digital panoramic radiographs can be used to evaluate bone quality for implant recipient sites.

        항생제 혼합 시멘트 정을 이용한 장관골 감염성 불유합의 이단계 치료

        조세현,정순택,박형빈,황선철,하용찬,황인환 대한골절학회 2004 대한골절학회지 Vol.17 No.4

        목적: 장관골 감염성 불유합의 치료 시 항생제 혼합 시멘트 정을 이용한 이단계 재건술의 결과를 분석하고자 한다. 대상 및 방법: 1998년 1월부터 2002년 9월까지 장관골 감염성 불유합으로 이단계 재건 수술을 받은 41예 (대퇴골 26예, 경골 15예)를 대상으로 하였다. 일단계 수술에서는 광범위한 변연 절제술, 부골 제거 및 세척술과 기존 고정 장치의 제거 또는 외고정 장치로의 교환을 시행한 후 시공 (dead space)과 불유합 주변 연부조직 내 항생제 혼합 시멘트 정을 삽입하였다. 임상적 감염 증상이 호전된 평균 8.7주 (3주~32주) 후 이단계 재건술로서 Ⅰ군은 내고정 장치 (금속판 5예, 골수강내 금속정 8예), Ⅱ군은 외고정 장치 (Ilizarov 25예, Monofixator 3예)로 각각 고정하고 17예에서는 골내 이동술이나 골 연장술을 시행하였다. 양군 모두 필요한 경우 골 이식과 시멘트 정의 교환을 추가하였다. 추시 기간은 16개월에서 최장 71개월로 평균 45개월 이었다. 치료 결과는 골유합 기간 및 Paley 방법에 의한 방사선상 골유합 상태와 하지 기능으로 평가하였다. 결과: Ⅰ군 13예 전부와 Ⅱ군 28예 중 26예에서 감염의 치료와 골유합을 얻었다. 이단계 재건술 후 골 이식술, 골 소파술, 외고정 핀 교환과 각변형 교정술, 피부 이식 또는 근육 피판 회전술 등의 보조적 시술이 Ⅰ군은 평균 2회, Ⅱ군은 평균 6.2회 추가되었다. 평균 골유합 기간은 Ⅰ군이 19.3주이고 Ⅱ군이 23.1주로 내고정군이 더 빨랐다. 방사선상 Paley 골유합 상태는 Ⅰ군이 우수 8예, 양호 5예이었고, Ⅱ군이 우수 18예, 양호 7예, 보통 1예, 불량 2예 이었다 (p=0.492). 기능적 결과는 Ⅰ군에서 우수 6예, 양호 6예, 보통 1예 이었고, Ⅱ군에서는 우수 10예, 양호 13예, 보통 3예, 불량 2예 이었다 (p=0.267). 결론: 항생제 혼합 시멘트 정의 골수염 치료 효과가 관찰되었으며, 감염이 호전된 후 내고정 장치로 교환해 준 군이 외고정을 유지한 군에 비하여 추가 수술 횟수가 적고, 골유합 기간도 빨랐다. Purpose: To evaluate treatment results between internal na external fixation groups in two-stage reconstruction of infected nonunion of long bones using antibiotics-impregnated cement beads. Materials and Methods: In the first stage, preexisting hardwares were removed and radical debridement was done. The dead space was filled with antibiotics -impregnated cement beads and the nonunion sits was immobilized by external fixation, cast or skeletal traction. In the second stage, all cases were divided into two groups; the nonunion was fixed by internal fixation in group Ⅰ versus external fixation in group Ⅱ. The intervening period between the first and second stage was average 8.7 weeks (range, 3~23 weeks). Results: The follow-up period was average 45 months (range, 16~71 months). Infection control and bone union were achieved in all 13 cases of group Ⅰ. Infection recurred in two of 28 cases in group Ⅱ, one underwent above-knee amputation and the other case was lost in follow-up. The mean number of supportive operations including repeated curettage, augmentation and change of infected pins, angular correction, and soft tissue flap was average 2 and 6.2 times respectively in group Ⅰ and group Ⅱ. Bony union period was average 19.3 and 23.1 weeks in each group. According to Paley's classification, group Ⅰ was similar to group Ⅱ in bony and functional result (p>0.05). Conclusion: Antibiotics-impregnated cement beads provided positive effect on infection control. Internal fixation group showed less number of additional operations and earlier bony union than external fixation group.

        치수유래 구심성 신경섬유의 삼차신경 감각핵군에서의 연접특성

        배용철,이은희,최민기,홍수형,김현정,남순현,김영진 대한소아치과학회 2001 大韓小兒齒科學會誌 Vol.28 No.2

        일차연접부위에서 악안면 영역에서 유래하는 유해자극의 전달 및 처리기전을 이해하고자 horseradish pe개xidase를 치수지배 구심성 신경섬유를 표식한 후 연수후각에서 미세구조 및 연절 양상을 분석하여 다음과 같은 결과를 얻었다. 표식종말은 소수의 큰 치밀소포가 관찰되는 종말 (S형) 및 다수의 치밀소포를 함유하는 종말 (LDCV형)등 2종류로 분류할 수 있었다. S형 및 LDCV형 표식종말의 연접양식은 유사하였으며, 다수의 표식종말이 1개 혹은 2개의 neurofile과 연접을 이루어 대단히 단순한 연접양상을 보였다. 표식종말은 가지돌기체 보다는 다수의 가지돌기가시와 연접을 이루는 빈도가 높았다. 표식종말이 세포체 및 이에 인접한 근심부 가지돌기와 연접하는 경우는 드물었으며, 소수의 표식종말에서 p-ending과 연접하는 경우를 보였다. 표식종말의 체적, 표면적, 사립체의 체적, neurofile과 접하는 면적, 활성부위의 면적, 단위표식종말당 연접소포의 수 및 연접소포의 밀도등은 넓은 범위의 계측치를 나타내었으며, 이는 5명 및 LDCV형 표식종말 사이에 유의한 차이가 없었다. 이상의 결과로 미루어보아 연수후각에서 치수유래 구심성 신경섬유 종말의 연접양식은 고유의 특징을 보이며 이는 신경회로의 기능과 밀접한 상관관계를 가지는 것으로 판단되었다. Little is known about processing mechanism of pain sensation of the oral cavity at the 1st synapse of trigeminal sensory nuclei. Serial ultrathin sections of tooth pulp afferent terminals, identified by the transganglionic transport of 1% wheatgerm agglutinin conjugated horseradish peroxidase, were investigated wih electron microscope. Quantitative ultrastructural analysis was performed on digitizing tablet connected to Macintoshi personal computer (software: NIH Image 1.60, NIH, Bethesda, MD). Labeled boutons could be classified into two types by the shapes of containing vesicles : S bouton which contained mainly spherical vesicles (Dia. 45-55 nm) and few large dense cored vesicles (Dia. 80-120nm), and LDCV bouton, which contained spherical vesicles as well as large number of large dense coredd vesicles. Most of the parameters on the ultrastruotural characteristic and synaptic organization of labeled boutons were similar between S and LDCV boutons, except shapes of containing vesicles. Majority of the labeled boutons showed simple synaptic arrangement. The labeled bouton were frequency presynaptic to dendritic spine, and to a lesser extent, dendritic shaft. They rarely synapsed with soma and adjacent proximal dendrite. A small proportion of labeled boutons made synaptic contacts with presynaptic pleomorphic vesicless containing endings and synaptic triad. Morphometric parameters of labeled boutons including volume and surface area, total apposed area, mitochondrial volume, active zone area, vesicle number and density showed wide variation and theme were not significantly different between S and LDCV boutons. The present study revealed characteristic features on ultrastructure and synaptic connection of pulpal afferents which may involved in transmission of oral pain sensation.

        재식한 흰쥐 구치 치수조직의 재혈관화와 CGRP 면역반응 신경섬유의 변화

        배용철,이승봉,김영진,남순현,김현정 大韓小兒齒科學會 1999 大韓小兒齒科學會誌 Vol.26 No.4

        치아 재식 후 시간경과에 따른 치수조직의 재혈관화와 신경재지배의 변화를 관찰하기위해 생후 35일된 흰쥐(Sprague dawley) 56마리를 대상으로 상악우측 제1대구치를 발치 즉시 재식한 후 1일, 2일, 3일, 1주, 2주, 4주, 6주 간격으로 희생시켜 먹물을 이용한 혈관조영술과 CGRP를 이용한 면역조직화학적방법으로 각기 시행하여 다음과 같은 결론을 얻었다. 1. 재혈관화와 CGRP 면역반응신경섬유의 재지배는 재식후 1일에서 근심측 치수조직에서는 이미 이루어졌으나 원심측은 미약했다. 재식후 2일에 전치수조직에서 재혈관화와 신경재지배가 이루어졌으며 이후 6주까지 시간경과에 따라 분포밀도가 증가하였으나 대조군에 비해서는 약하게 나타났다. 2. 재식후 1주에서부터 술후 상아질이 형성되기 시작하였으며 재식후 6주에서는 대조군에 비해 상대적으로 치수강이 좁아진 양상을 보였다. 3. 재혈관화와 신경재지배는 거의 같은 시기에 이루어지는 것으로 나타났으며 밀접한 관련성이 있는 것으로 보인다. The purpose of this study was to investigate the revascularization and reinnervation of calcitonin gene-related peptide immunoreactive nerves in immediately replanted rat molars. First maxillary right molars in 56 rats(35days old) were extracted and immediately replanted. The rats were killed 1, 2, 3, 7, 14, 28 and 42 days after replantation and revascularization of pulpal blood vessels were examined microangiogram with korean traditional ink and reinnervation of pulpal nerve were examined immunohistochemical method using calcitonin gene-related peptide(CGRP) antiserum. The results were as follows; 1. Revascularization and reinnervation of CGRP immunoreactive nerve fibers were observed mesial side whole pulp tissue of replanted teeth. Revascularization and reinnervation of CGRP immunoreactive fiber were made at 2days after replantation in entire pulp of replanted teeth and the distribution density of blood vessels were gradually increased according time elapsed, but did not achieve the density of control. 2. Postoperative dentin formation in replanted teeth revealed at 1 week after replantaton and gradually increased according to time elapsed. 3. Revascularization and Reinnervation of CGRP immunoreactive nerve fibers were established at the same time and it seems to be closed relatationship between revascularization and reinnervation.

      • 망막병증을 동반한 제2형 당뇨환자에서 vitamin E투여후 단핵구 manganese superoxide dismutase(Mn-SOD)의 활성도 변화

        배현철,최성남,공병호,오연상,신순현 중앙대학교 의과대학 의과학연구소 1998 中央醫大誌 Vol.23 No.1

        There are some evidences that oxidative stresses have some roles in initiation and progression of the diabetic complications. Superoxide dismutase (SOD) is an essential enzyme for the dismutation of superoxide(:O2^-) radicals, and the activity is changed in some pathologic conditions such as diabetes. The aim of this study was to evaluate the association of Mn-SOD activity and severity of diabetic retinopathy and to compare between before and aftertreatment with vitamin E. The Mn-SOD activities were measured in 75 patients with NIDDM(41 noretinopathy, 21 nonproliferative retinopathy, 13 proliferative retinopathy) by spectrophotometry. The Mn-SOD activity(U/mg protein) was significantly elevated in diabetes after vitamin E treatment. The severity of diabetic retinopathy appeared not be statistically significant. In diabetic patients, there were no correlation between the Mn/SOD activity and the various clinical and biochemical parameters.

      • 니페디핀이 암피실린의 흡수에 미치는 영향

        정현정,용철순,최윤수,오두만 영남대학교 약품개발연구소 1997 영남대학교 약품개발연구소 연구업적집 Vol.7 No.-

        Amino-β-lactam antibiotics are absorbed by the dipeptide transporter in the small intestine. These uptakes are coupled to a proton influx. The inward proton gradient is partly induced by the Na^(+)/H^(+) exchanger and cakium ion is involved in control of this antiport. Interaction between ampicillin which is one of the amino-β-lactam antibiotics and nifedipine which is one of calcium channel blocking agents was studied in rats in vivo and with rabbit jejunum mounted on the Sweetana/Grass diffusion cells in vitro. Bioavailability of ampicillin was increased significantly when nifedipine was co-administered orally in rats. There were no differences in the distribution phase and the elimination phase when ampicillin was given either alone or with nifedipine intravenously. Conditions for in vitro experiments were determined. The lift rate of O₂/CO₂ gas was controlled to 3 bubbles/sec and ampicillin was stable in the Kreb's buffer at pH6.0 Absorption of ampicillin was the greatest when the completely-stripped serosal membrane was used. Transport of ampicillin from mucosal to serosal side in the rabbit jejunum was enhanced by 32% in the presence of nifedipine (p=0.059). Above results suggest that nifedipine might increase the plasma level of ampicillin via the improved absorption in the intestine rather than the reduction in the elimination or/and alteration in the distribution.

      • 光合成 細菌에 대한 硏究 : Ⅰ.Rhodospirillum rubrum의 Polyphosphate 生合性에 있어서 燐散源에 따른 差異 Ⅰ. The Differences on Polyphosphate Biosynthesis by the Phosphate Source in Rhodospirillum rubrum

        吳德鐵,李賢順 제주대학교 1983 논문집 Vol.16 No.-

        1. 光合成細菌 R. rubrum을 Ortho P, Pyro P가 各各 包含된 培地로 明ㆍ暗狀態로 培養하여 收率, pH變化, Polyphosphate含量등을 조사하였다. 2. pH는 Ortho P배지보다 Pyro P배지에서 더 높았다. 3. 收率은 明培養때는 Ortho P배지에서가 낮고 暗培養인때는 反對였다. 4.
