Spontaneous rupture of hepatocellular carcinoma (HCC) is one of the most serious complication of HCC. Immediate diagnosis and proper management are important for prolongation of survival rate of the HCC patients. We experience spontaneous rupture of HCC with hemodynamic study of CT and performed hepatic angiography with embolization. Authors report imaging findings of spontaneous rupture of HCC.

이야기(narrative)에 나타난 도덕 발달의 탐색

김형철,최병학 釜山大學校 師範大學 2001 교사교육연구 Vol.40 No.-

Human history is an endless narrative. Human beings understand and interpret their world in a narrative. We see and listen to small narratives through myths and legends in order to make our self identification. Furthermore, we identify with larger community and realize our identity as a member of it. Narratives reveal an individual historical context which enables one to interpret human life and helps us to understand human behavior more concretely. Men make a narrative about their lives and it interwoves the past, Present and future into narrative structure. During this process moral problem is risen as a narrative of his individual life, and this meaningful horizon of narrative would be a momentum for understanding others as well as understanding himself. The objective phases revealed in a narrative functions as the ethic momentum with others. Constructing his life and experience into a story with these grounds makes it possible to understand human fundamentally. Considering these phases in relation to moral development, narrative makes it possible to understand the integrative phase of morality and shows the context of meaning which covers cognitive and affective area. For the moral development, the special importance and practical knowledge of narrative can reveal the meaning of human experience necessarily. Narrative has to do with our small narratives as well as literature, It is indicative of general human desire for narrative. Accordingly a narrative thought which can encompass the definitive and abstract principle needs to be deepened in relation to an educational purpose. This perspective demands an educational direction and a creative alternative.

Purpose: To evaluate the relation of internal echo and enhancement patterns on three phase spiral CT in hepatic hemangioma. Methods: This retrospective study included 41 cases in 34 patients who were diagnosed as hepatic hemangioma who had ultrasonography and three phase spiral CT scan. We classified hepatic hemangioma as two different groups according to the findings of internal echo on ultrasonography. Three phase spiral CT images were obtained at 30 seconds(arterial phase), 60 seconds( portal phase), and 3-5minutes(delayed phase) after the initiation of injection of contrast materials(120ml, 2.7ml/sec). Enhancement patterns of hemangiomas during three phases were classified as total high attenuation, peripheral high attenuation, low attenuation, or iso attenuation. Results : The most common enhancement pattern of hemangioma on three phase spiral CT was peripheral high attenuation in whole three phases in both high and low echoic groups. There was no statistical significance(P>0.1). Total high attenuation in whole three phases on three phase spiral CT is 3 cases(3/13, 23%) in low echoic group and 1 case(1/28, 4%) in high echoic group. It is statistically significant(P<0.1). Conclusion: The enhancement patterns on three phase spiral CT is different between low and high echoic group. Total high attenuation in whole three phases on three phase spiral CT is more in low echoic group than in high echoic group.

서사와 여성주의 도덕교육

Comtemporary approach to moral education emphasize propositional thinking and socratestic verbal discussion of abstract moral dilemmas. In contrast, this article proposes that narratives are a central factor in moral education and feministi moral education. Support for this position comes from recent theoretical contributions of Bruner, Hoffman, Maclntyre, Gilligan and others, who have emphasized narrative thought as a major form of cognition that is qualitatively different from abstract propositional thinking. By the way, narrative has the opposing two aspects regarding gender equality, both of liberating and repressive effects on moral education. Narrative method of character education and virtue education is related to the traditional male values. In this respect, narrative becomes a repressive space for women. However, women can make narrative as a liberating space for them by promoting gender equality. It is proposed that narratives and narrative thinking are especially involved in how these processes lead to moral development and therefore that narrative should be rehabilitated as a valuable part of feministi moral education.

This study was intended to suggest the desirable direction in the 7th national curriculum revision through the comparative analysis of the physical science domains of the primary science textbooks between the 5th and 6th national curriculum. The analysis system were composed of three categories. (1)problem presentation (2)inquiry process and (3)knowledge. and inquiry process is divided into twelve subcategories such as observation, classification, measurement, prediction, inference, formulating hypothesis, operational definition, controlling variables, interpretation of data, formation of model, experiment, and record and communication. And knowledge was divided into fact, concept and rule. Each sentence in the textbooks was considered as and analyzing unit. The frequency and percentage of each category were counted and the rate was calculated. The finding could be summarized as follows; 1. The names of chapters were a little different in both curricula, and the contents were similar. In the 6th curriculum, the number of pages were increased, but that of sentences were reduced except for two chapters. 2. the rate of problem presentation and knowledge were less, but that of inquiry processe was more in the 6th curriculum then in the 5th curriculum. So, we could find out that in the 6th national curriculum, inquiry process was more emphasized.

중추에서 Prostaglandin계가 Renin-angiotensin System에 미치는 영향

Role of prostaglandins on the renin-angiotensin system in the central nervous system was examined in normotensive and 2-kidney, 1 clip (2K1C) hypertensive rats. The experiment was done under thiopental (50 ㎎/㎏, IP) anesthesia. Captopril and indomethacin were injected into the right lateral cerebral ventricle. Arterial blood pressure and heart rate were recorded from the femoral artery. Intracerebroventricular (ICV) captopril (1 ㎎) caused a decrease in mean arterial pressure in both normotensive and 2K1C hypertensive rats. The depressor response to captopril was more sensitive in hyper-tensive rats than in normotensive rats. Indomethacin treatment (ICV, 200 ㎎) altered the depressor response to captopril neither in normotensive nor in hypertensive rats. These results suggest that the cardiovascular effect of renin-angiotensin system in the central nervous system may not be mediated via prostaglandin systems in normotensive and 2KlC hypertensive rats.

한창욱,김형진,김철진 慶北大學校 醫科大學 1997 慶北醫大誌 Vol.38 No.1

목적 : 두부 상하위가 운동후 회복기 심혈관계 조절에 미치는 효과를 구명하고자 하였다. 대상 및 방법 : 20-23세 남자 대학생 31명을 대상으로 하여 3분간의 rebounder 운동을 실시한 후 15도의 두부상위, 15도의 두부하위 또는 앙와위에서 20분간 회복 중 심박수, 혈압 및 호흡수의 변화를 측정하였다. 대상자는 운동을 하지 않고 두부상위 (U, 6명) 또는 두부하위 (D, 6명)를 취한군과 운동후 두부상위 (EU, 7명), 두부하위 (ED, 6명) 또는 앙와위 (ES, 6명)를 취한 군으로 나누었다. 결과 : U 및 D군에서는 심박수, 혈압 및 호흡수에 유의한 변화가 없었다. EU군에서 운동후 1분에 심박수, 수축기 혈압 및 호흡수는 각각 109.2±17.9 beats/min, 168.3±7.6 mmHg 및 27.3±1.9 breaths/min로서 비운동군에 비해서는 유의하게 높았으나, 심박수는 안정시에 비해 유의한 증가를 보이지 않았고, 회복기 5분 이후 평균동맥압은 안정시 및 비운동군에 비해 낮은 경향을 보였다. ED군에서 운동후 1분에 심박수, 수축기 혈압 및 호흡수는 117.4±7.7 beats/min, 155.0±13.4mmHg 및 33.2±1.4 breaths/min로서 비운동군에 비해서는 유의하게 높았으나, 회복기 1 및 5분의 수축기 혈압은 ES 군에 비해 유의하게 낮았고, 평균동맥압은 회복기 1∼3분 동안 불안정하였고 5∼15분 사이에는 계속 감소하는 경향을 보였다. 결론 : 이상의 결과로 볼 때 운동후 회복기에 두부상위 자세는 동맥압 조절능력을 약화시키며 두부하위 자세는 동맥압 조절기전을 불안정하게 하는 것으로 생각된다. In an effort to elucidate the effect of head-up and down tilt on the cardiovascular regulation during recovery period after exercise, 31 healthy male college students aged between 20-23 yr were employed to exercise on a rebounder for 3 min and to take 15° head-up tilt, 15° head-down tilt or supine position for 20min during which heart rate, blood pressure and respiratory rate were measured. The subjects were divided into 5 groups: head-up tilt without exercise (U, n=6), head-down tilt without exercise (D, n=6), head-up tilt after exercise (EU, n=7), head-down tilt after exercise (ED, n=6), supine position after exercise (ES, n=6). Heart rate and respiratory rate were measured from an electrocardiogram and pneumogram recored with a physiograph. Blood pressure was measured with a mercury sphygmomanometer. 1. In non-exercise groups (U, D), there were no significant change in heart rate, blood pressure and respiratory rate. 2. During head-up tilt after exercise (EU), heart rate, systolic pressure and respiratory rate at 1 min were 109.2 ± 17.9 beats/min, 168.3 ± 7.6 ㎜Hg and 27.3 ± 1.9 breaths/min, respectively, which were significantly higher than in the non-exercise group (U). Heart rate did not show a significant increase compared with rest. Mean arterial pressure at 5 min and thereafter tended to be lower than at rest or in the non-exercise group. 3. During head-down tilt after exercise (ED), heart rate, systolic pressure and respiratory rate at 1 min were 117.4 ± 7.7 beats/min, 155.0 ± 13.4 ㎜Hg and 33.2 ± 1.4 breaths/min, respectively, which "were5 significantly higher than in the non-exercise group (D). Systolic pressure at 1 and 5 min was significantly lower than in the non-exercise group. Mean arterial pressure was unstable during 1-3 min and tended to progressively decrease during 5-15 min. It was concluded therefore that head-up tilt during recovery period after exercise might compromise the arterial pressure regulation system whereas head-down tilt might render the regulation mechanism unstable.

Appendicitis is the most common acute abdomen in Emergency Medical Center & outpatient department. But sometimes, it is difficult for us to diagnose because of clinically variable symptoms. We reviewed the ultrasonographic findings and analyse 521 cases of appendectomy patients about its distribution of sex and age, seasonal prevalence, clinical symptom and signs, laboratory findings, duration from onset of symptom to arrival at hospital, duration from arrival at hospital to operation, vital signs, operative results, and associated diseases, which were treated at the department of General Surgery & Emergency Medical Center in Chung Ang Gil Hospital from July, 1994 to June, 1995. The results were as follows : 1. The most common age group was second decade. And male to female ratio was 1.43:1. Seasonal variation was not significant. 2. Of 521 cases, 141 cases(27.1%) visited the hospital within 24 hours from the onset of symptom, and 259 cases(49.7%) visited between 24 to 48 hours. 3. In duration from arrival to operation, the cases within 6 hours were 263 (50.5%), the cases between 6 and 12 hours were 131(25..1%). 4. In systolic blood pressure, cases below 90mmHg were 19(3.6%), cases above 160mmHg were 23(4.4%). Below 60mmHg diastolic pressure were 55 cases(10.6%), cases above 110mmHg were 9(1.7%). In pulse rate, above 90 rate/min were 171(32.8%). 5. On admission leukocytosis was found in 413 cases(79.3%) and 342 cases of them were pathologic appendicitis. 6. Ultrasoundgraphy was performed in the 87 cases, but 23 cases were suggested appendicitis. Among 23 cases, 22(95.7%) revealed pathologic appendicitis at ooperation and labortatory examination. Of the 64 cases which were normal on ultrasonography, only 2 cases(3.1%) were proved to be appendicitis. 7. The results of 496 operations without ultrasonography were appendicitis in 390 cases(78.6%), mesenteric lymphadenopathy 36(7.3%), pelvic inflammatory disease 28(5.6%), fecalith 15(3.0%), terminal ileitis 8(1.6%), diverticulitis 7(1.4%), urinary tract stones 5(1.0%), cecal cancer 2 cases, right ovarian tumor 2 cases, tubo-ovarian abscess 2 cases, grater omentum internal hernia 1 case. Our results showed that the sensitivity of ultrasonohraphy was 95.8% and the specificity 98.4% in the diagnosis of appendicitis, It suggests that the ultrasonography is very helpful in the diagnosis & differential diagnosis of acute appeendiditis.

교육대학원에 있어서 초등 과학교육 영역의 중요성과 그 운영방안

오진태,옥치율,한영욱,이형철,김용권,임채성 釜山敎育大學校 1994 부산교육대학 논문집 Vol.30 No.1

The future society is expected to be rapidly change in all areas, that is, the length of change time is becoming much smaller than that of generation time. It is very important to prepare the citizens who possess scientific literacy which actively cope with the rapid changes and specialization of society. The sources of rapid changes may be due to the developments in science and technology. Therefore, the importance of science education will be increasingly high. Scientific literacy should be improved basically and systematically from the early stages of formal education. Teachers who are responsible to educate children should be able to research in the areas of science education as well as science itself, and to have capacity to transmit them to the classroom. To do this, the graduate course and the science education within the system beyond the level of college education are essential parts of teacher education. In the graduate course, it is important that science itself and pedagogy of science should be balanced.

정원일,우승효,이형래,이상철,김용태,김원재 충북대학교 의학연구소 2000 忠北醫大學術誌 Vol.10 No.2

연구목적 : 성교가능 성인남자의 급성 부고환염에서 Chlamydia trachomatis가 차지하는 빈도를 Nested PCR을 통해 검출하여 보고자 하였다. 대상 및 방법 : 1996년 9월부터 1999년 2월까지 본 충북대학교 병원 비뇨기과 외래 및 응급실을 내원하여 급성 부고환염으로 진단된 환자 중 성교가능 성인남자 28명을 대상으로 하여 환자로부터 얻은 뇨검체로 일반 미생물 배양검사, 그람염색검사 및 Chlamydia PCR을 시행하였다. 결과 : 급성 부고환염으로 진단된 28명의 평균 연령은 30.9±12.4세 였으며 총 28명중 17명 (60.7%)에서 Nested PCR 검사에 양성으로 나타났으며 연령별로는 20대가 10명중 7명(70%)으로 가장 높은 양성율을 보였다. 그람염색도말 결과 28명중에서 6명(21%)이 비임균성 요도염에 양성을 나타냈으며 또한 일반 미생물 배양 검사 결과 2명에서 균이 자랐는데, 각각 S. epididermidis와 E. coli였다. 결론 : PCR을 통한 Chlamydia trachomatis의 검출이 지금까지 행해진 다른 검사 방법들에 비해 월등하게 민감도가 높으며 성접촉이 가능한 연령의 성인 남자가 급성 부고환염 증세로 내원시 기본적으로 PCR을 통한 Chlamydia trachomatis 검출 검사를 시행하여 적절한 치료가 이루어지는 것이 중요할 것이다. Purpose : We studied the incidence of Chlamydial epididymitis in sexually active male with acute epididymitis by the Nested polymerase chain reaction( PCR ). Materials and Methods: Urine specimens, collected from 28 patients that was 30.9±12.4 years old and presented with acute epididymitis, were tested for the presence of Chlamydia trachomatis by the Nested PCR and for other bacteria by the urine gram stain and culture. Results: Out of total 28 patients, 17 patients(60.7% ) showed positive for Chlamydia trachomatis by the Nested PCR. In thirtieth decade, 7 of 10 patients(70%) showed positive, revealed the highest incidence. 6 patients(21%) showed positive for other bacteria by the urine culture. Conclusion: Detection rate of Chlamydia trachomatis by the Nested PCR was higher than other current diagnostic technique. For the high incidence of Chlamydial epididymitis, all men with acute epididymitis should undergo Chlamydia trachomatis evaluation for adequate treatement of this infection.
