급성 심근염환자에서 발행한 완전 방실차단을 영구 심장박동 조율기로 치료한 1예를 경험하였기에 문헌고찰과 함께 보고하는 바이다. Myocarditis, an inflammatory process involving the myocardal wall, may be caused by most infectious agents. Irrespective of its etiology, it presents commonly with evidence of heart failure, hypotension, and various electrocardiographic abnormalities. Patient with myocarditis may be asymptomatic or may have a rapidly progressive fatal disease. Medical management of patients with myocarditis includes specific therapy for underlying infection and control of the complication of myocarditis such as congestive heart failure and arrhythmia. Recently we had experienced myocarditis with complete atrioventricular block in 37-year-old man. Although he had shown complete recovery of heart failure, he had shown complete atrioventricular block, so we inserted permanent pacemaker. We report it with review of the literature.

Stenosis of central vein is a common complication arising after percutaneous subclavian vein catheter insertion performed for temporary vascular access in chronic renal failure patients undergoing hemodialysis. There are several treatment methods for the condition like percutaneous angioplasty(PTA), stent insertion, and surgery, but recent trend is toward PTA and stents. Among the patients diagnosed with chronic renal failure from March 1993 to May 2002 and undergoing hemodialysis through AV fistula, the 14 Patients in whom central vein stenosis arose were selected for the study. A total of 28 percutaneous interventions(5 PTA and 23 stent placement) were performed, and restenosis rate and the time taken till the restenosis in de novo lesions and instant lesions were compared. All 28 cases were operated successfully. The 14 cases that received both anigioplasty and stent placement initially. (de novo lesion : 14 cases), Among the 10 cases with de novo lesion that followed up more than 1 year, 3 cases are currently undergoing hemodialysis without restenosis, and the remaining 7 cases have recurred stenosis with the mean time to restenosis of 10.9 months. In the 7 cases in whom stenosis recurred, 11 interventions were done(instent lesion: 11 cases). 4 of these were using only ballon angioplasty with 100% restenosis rate and the mean time of 3 months until restenosis. The remaining 7 cases were using both balloon angioplasty and stent placement, also with 100% restenosis rate but with the mean time of 12 months until restenosis, which was later than the group receiving only balloon angioplasty. In treating the patients with central vein stenosis, stent placement seems to be more advantageous over PTA in terms of restenosis rate and the mean duration of patency. In the case of instent lesion, inserting the stent for the second time after stenosis recurred lengthened the duration of patency compared to performing balloon angioplasty alone.

관상동맥 질환에서 SDF-1α의 농도

김보영,박용규,박형서,노상필,정승현,이유선,이정우,이재환,최시완,정진옥,성인환 충남대학교 의과대학 의학연구소 2003 충남의대잡지 Vol.30 No.1

Atherosclerosis is now viewed as an inflammatory disease of the vascular system. Expression of several chemokines, including monocyte chemoattractant protein(MCP)-1, MCP-4, RANTES(regulated on activation normal T-cell expressed and secreted), and interleukin-8(IL-8) are increased in human atherosclerotic plaques compared with normal vessels. They are involved in the pathogenesis of atherosclerosis and plaque rupture by activating and directing leukocytes into the atherosclerotic lesions. However, some are involved in homeostatic functions such as normal leukocyte traffic and growth regulation. SDF-la is a multi-functional cytokine that is involved in myelogenesis, hematopoiesis, angiogenesis and injured gastric mucosal regeneration in the gastric ulcer patient. SDF-la is recently shown to be highly expressed in atherosclerotic plaques and a potent platelet agonist. At least in high concentrations, SDF-la may mediate antiinflammatory and matrix stabilizing effects in unstable angina. Many studies are going on to know the function of SDF-la in coronary artery diseases. I investigated the difference of the plasma level of SDF-la between control group and coronary artery disease group. Total 75 subjects were enrolled. The diagnosis of coronary artery disease was confirmed in all patients by coronary angiography. Control subjects in this study were confirmed normal by coronary angiography. Clinical profile and risk factors were also reviewed. Control subjects in this study were 27 (M=10, F=17). Plasma for the study was collected before the angiography and centrifuged. SDF-la analysis was performed by ELISA. Plasma level of SDF-la is significantly increased in patients with stable angina(n=20) and unstable angina group(n=28) compared with healthy control group(n=27). the risk factors do not influence the plasma level of SDF-la in coronary artery diseases. In this study, plasma level of SDF-la is increased in patients with stable angina and unstable angina groups compared with healthy control group(P<0.05). the risk factors do not influence the plasma level of SDF-la in coronary artery diseases.

정진근,김정완 한국스포츠심리학회 2003 한국스포츠심리학회지 Vol.14 No.1

본 연구의 목적은 국가대표 남자 체조선수들이 인식하고 있는 실수 원인을 면담을 통해 심층적으로 분석하여 실수 원인에 대한 정보를 제공함으로써 우수한 경기력 발휘에 어려움을 겪고 있는 일반선수들이나 현장에서 선수를 지도하는 지도자들에게 실수에 대한 대처방안을 강구할 수 있도록 하기 위함이다. 본 연구에서는 제14회 아시안 게임에 참가한 국가대표 남자 체조선수들을 대상으로 실수 원인을 밝혀내기 위하여 심층면담을 하였으며 면담을 통해 얻어진 자료를 귀납적 방법으로 내용 분석을 하였다. 내용 분석 한 결과는 다음과 같다. 실수의 원인은 신체적 요인, 심리적 요인, 인적 요인, 환경적 요인으로 모두 4가지 범주로 분류되었다. 신체적 요인의 범주 안에는 1가지의 원자료가 분류되었으며, 심리적 요인의 범주 안에는 가장 많은 8가지의 원자료가 분류되었다. 그리고 인적 요인에 3가지의 원자료가 분류되었고 환경적 요인에 1가지의 원자료가 분류되었다. 이러한 결과를 바탕으로 경기중 실수를 줄이기 위해서는 심리적 실수 유발 요인을 통제하는 것이 중요하며 따라서 실수의 심리적 원인에 적절히 대처할 수 있는 훈련과 연습이 필요하다는 제안을 하였다. The purposes of this study are to analyze the reasons of mistakes that male gymnastic players recognize through the interviewing and to plan to deal with those problems by presentation the informations about the reasons of mistakes to the general gymnastic players and the directors. This study makes the targets for the analysis the male gymnastic players that participated in the 14th Asian Games as the members of the national team. The materials that was drawn through the depth interviewing are analyzed inductively. The results of this study are as follows : The reasons of mistakes are classified into four categories : the physical factor, the psychological factor, the human relations factor, and the environment factor. There is a raw date in the physical factor, and 8raw date in the psychological factor. Then, there are 3raw date in the human relations factor, and a raw date in the environment factor. With these results in mind, the following recommendations may be possible. First, it is important that the psychological reasons are controlled to reduce the mistakes in the match. Second, it is necessary that the gymnastic players must practice and be trained to prepare the psychological reasons of the mistakes.

전기충격요법 사용에 관한 정신과의사의 견해 및 실시현황

정환증,변원탄 大韓神經精神醫學會 1983 신경정신의학 Vol.22 No.4

한국 정신과 의사 211명의 전기충격요법에 관한 의견을 다음과 같이 요약할 수 있었다. 1. 735가 치료방법으로서의 전기충격요법을 찬성하는 태도였고, 찬성하는 가장 큰 이유로서는 적응증만 잘 고려된다면 일반적으로 우수한 효과를 볼 수 있다는 것이었다. 그러나, 그 실제적인 사용에 있어서는 다수에서 조심스러운 태도를 보이고 있었고, 어떤 견해에 있어서는 미국의 정신과 의사들보다 훨씬 더 소극적인 태도를 가지고 있었다. 2. 전기충격요법의 적응증에 관한 한 역시 예상한 바와 같이 주요 우울장애, 조증 흥분, 정신분열증의 순으로 찬성하는 경향이 많았고, 이 방법을 선택한 이유로는 '응급처치로 시행하거나' 다른 치료방법에 실패했거나' '보다나은 결과를 얻기 위한 병용 치료로서 선택' 등이 가장 많았다. 3. 정신분열증에서의 전기충격요법은 사용의 한계를 나타내고 있었다. 4. 시행 이전의 동의나 시행 전 감사에 대해서는 비교적 엄격한 태도를 유지하고 있으나, 연성 전기충격요법, 편측 전기충격요법의 활용은 적었으며, 강력 또는 유지 전기충격요법 역시 시행율이 낮은 편이였다. 시행빈도는 79%가 주2-3회를 실시하는 것으로 나타났고, 향정신약물을 사용하던 환자에서 전기충격요법을 시행한 경우, 대체로 약간의 약물 감량을 실시하는 것으로 나타났다(59%) 5. 전기충격요법 시행 이후의 합병증으로는 골절이나 탈구, 직업 수행 능력에 영구적인 장애, 자발적인 경련 발작 등이 예상외로 많아 합병증은 역시 소홀히 할 수 없는 문제임을 나타내 보였으며, 전기충격요법 이후 24시간이내 사망을 경험한 예가 6경우가 있었다. The authors of this suveyed the opinions of 211 Korean psychiatrists about the use of Electoconvulsive Theraoy(ECT). The results of the survey are summarized as follows; 1. ECT was accepted with a favorable attitude by 73% of the psychiatrists surveyed. The most common reason for agreement was that if indication is followed the ECT generally produces excellent results. But in actual clinical practice most Korean psychiatrists are hesitant in preforming the ECT and have a somewhat less active attitude towards ECT than psychia trists in America. 2. The major indications for theuse of ECT were major depression, manic excithment and schizophrenia in the order of their frequency. The main reasons for the selection of ECT as a therapeutic tool were emergency therapy, when all other treatment methods have failed and as a combined treatment that can. 3. The use of the ECT for the treatment of schizophrenia was very limited for a few selected cases. 4. Korean psychiatrists showed relatively rigid adherence to obtaining the consent before ECT and the preoperational work-up. The softening and unilateral ECT had received little use in Korea and a similar tendency was shown towards intensive and maintenance ECT. Most psychiatrists(79%) tended to use the ECT 2 or 3 times a ewek with a majority of their patients. In cases where the ECT was used in concomitant with antipsychotic drug therapy, there showed a tendency for a slight reduction in drug dosages during the ECT. 5. Post-ECT complications and/or adverse effects were fracture, dislocation, premanent disability in occupational performane and spontaneous seizures etc. Occurrences of above complications seem to be mlre than expected in this study and this was not negligible. A total of six patients were known to habe expired within twenty-four hours after ECT.

Above 130 accessions of pepper consisting of 50 introductions from Mexico and Nepal, and resistant and susceptible controls were tested for resistance to bacterial wilt and to Phytophthora root rot at seedling stage by artificial inoculation. As the results, KC897, KC939, KC936 were newly found resistant to bacterial wilt in addition to already known resistance sources such as KC126, KC350, KC351, KC353. No new sources of resistance to Phytophthora root rot were found among the introductions from Mexico and Nepal.

自然科 敎育의 學習評價에 對한 硏究 : 形成評價를 中心으로 Centered on the Formative Evaluation

林貞煥 대구교육대학교 1975 論文集 Vol.11 No.-

Compared with the existing view of evaluation, its new concept has been broadened and diversified. The present evaluation emphasizes its administrative and functional aspect while the new one places emphasis on its guiding and researching aspect. The desirable types of the evaluation of the elementary science education are summarized in three: Diagnostic, Formative and Summative evaluation. The thing to be stressed most in the evaluation of the elementary science education may be the procedure of the formative evaluation. It is as follows: 1. The learning objectives of the unit are subdivided into the actual behavioral objectives. 2. The unit to be studied is analyzed and selected. 3. The components included in the unit are analysed and an analysed evaluation chart is made. 4. Evaluation questionnaire is made and finally the evaluation begins.

중력장에서 입자층의 탈액체에 관한 연구

睦廷均,車岷煥 서울市立大學校 1990 論文集 Vol.24 No.-

To obtain a more simplified method for analyzing the dewatering mechanism of particulate beds in gravitational field the conventional equation for flow in capillaries is empirically modified in view of the existence of filmwise liquid. A simple equation for prediction the average saturation vs, the time is presented, by considering the beds as an assembleage of circular monosize capillaries determined from packed bed porosity and particle size. The progress of dewatering process can be followed using local saturation data measured throughout depth of the bed by means of the electrical conductivity, and good agreement has generally been found between computed and experimental data. It is obtained in terms of the average saturation and Zeitz number(Nzt). ??

In this study, the inquiry learning process in the elementary science learning, which the inquiry learning should be emphasized and not carried out in its own way, is analysized as one of the present problems. The causes of them were found in various conditions but among them, the factors that the present evaluation was not carried out well as a remarkable way were analysized considerably high. Therefore when the evaluation implement and method which can not be answered without a direct experience of Inquiry Learning process should be developed, the following evaluation ways were groped on the assumption that normal inquiry learning should be carried out: 1) The objectives of unit was analysized in its scope the unit evaluation percentage table and evaluation element table were made and then by those tables the rating scale and Evaluation items were made and used. 2) The evaluation items for the scientific thoughts were made and used. 3) The Performance test items were made and used. 4) Self evaluation items were made and used. When the evaluation is carried out with this implement by this method, a right inquiry learning process will be carried out at the classes in the school and it assumes me that inquiry ability, scientific attitude and its skill will be evaluated fully well.
