목 적 : 정 신분열병 환자의 자기만입 정도에 영향을 미치는 인구학적 변인들 및 질병연관 변인들을 규명해 보고자 하였다. 또한. 환자들의 자기만입과 병식 사이의 연관성. 자기만입과 자존심 사이의 연관성을 알아보고자 하였다. 방 법 : 정신과 의사가 병록지와 면담을 통하여 대상 정신분열병 환자들의 인구학적 변인들 및 질병연관 변인들에 관한 자료를 얻고 환자들의 병식 정도를 평가한 후, 환자들로 하여금 자기보고형의 자기만입 척도와 자존심 척도를 시행하게 하였다. 총 111명의 환자가 연구대상으로 선택되었다. 결과: . 1) 여자가 남자보다 유의하게 높은 자기만입 척도 점수를 나타내었다 2) 질병연관 변인들 중 하위집단 사이에 자기만입 척도 점수의 유의한 차이를 보이는 변은 없었다. 3) 자기만입 척도 점수와 병식 점수 사이에 유의한 상관관계가 없었다. 4) 자기만입 척도 점수와 자존심 척도 점수 사이에 유의한 역상관 관계를 보였다. 결 론 : 본 예비 연구의 결과로 보아 정신분열 병 환자의 병식이 부족한 상태에서도 자기만입이 진행될 수 있으며. 자기만입이 심할수록 환자의 자존심이 저하되는 것으로 생각된다. 또한 여자 환자들이 남자 환자들보다 자기만입에 더 취약한 것으로 생각된다. 따라서 정신분열 병 환자의 이해와 치료를 위하여 자기만입에 관한 지속적인 연구가 필요할 것으로 생각된다. objective : This study was conducted to identify demographic variables and illness related variables which may affect the severity of self-engulfment in the patients with schizophrenia. We also studied the relationship between self-engulfment and insight, and the relationship between self-engulfment and self-esteem. Methods : Data on demographic variables and illness related variables for the subjects were gathered from hospital records and clinical interviews by the psychiatrists. Degree of insight for the subjects was assessed through clinical interviews by the psychiatrists. Degree of self-engulfment and self-esteem for the subjects was assessed from the self-engulfment scale and the self-esteem scale respectively. A total of 111 patients with schizophrenia were selected for statistical analysis. Results 1) The females exhibited significantly higher scores than the males on the self-engulfment scale. 2) There was no illness related variable, which exhibited a significant difference among subgroups on the self-engulfment scale. 3) There was no significant correlation between the self-engulfment scores and the insight 4) There was a significantly inverse correlation between the self-engulfment scores and the self-esteem scores. Conclusion : The results of this preliminary study suggest that self-engulfment may develop despite lack of insight and that there was inverse relationship between self-engulfment and self-esteem in the patients with schizophrenia. It also suggests that females are more subject to self-engulfment than males. So, authors suggest that it is valuable to do further studies of self-engulfment in the patients with schizophrenia.

세슘은 높은 수용성으로 인하여 인체에 쉽게 침투하여 암 또는 DNA의 변형을 유발하는 잠재적인 독성 오염물질이다. 본 연구에서는 활성탄소의 세슘 흡착 능력을 향상시키고자 오존 처리를 통하여 활성탄소 표면에 산소 작용기를 도입하였다. 오존 처리 시간의 증가에 따라 활성탄소 표면의 산소함량이 증가하였다. 이후 활성탄소와 세슘 사이의 정전기적 상호작용이 더욱 원활하게 이루어져 모든 시료의 세슘 이온 흡착 효율이 향상되었다. 특히 반응기 내부 오존 농도를 50000 ppm으로 하여 7 min 동안 오존 처리한 시료는 약 12%의 높은 산소 작용기 함량을 보이며 97.6%의 가장 높은 세슘 제거 효율을 보였다. 한편, 5 min 동안 처리된 시료는 7 min간 반응한 시료와 비교하여 0.3%의 근소한 세슘 제거율 차이를 보였으며, 이는 오존 기체의 반응 특성으로 인한 두 시료의 표면화학적 유사성에 기인한다. 그러나, 오존 처리된 활성탄소의 세슘 흡착 성능은 활성탄소의 비표면적 및 기공 구조도 중요하지만 표면에 도입된 산소 작용기 양이 주된 영향을 미치는 것으로 판단된다. Cesium is a potential toxic contaminant due to its high solubility, which allows it to easily penetrate the human body and potentially induce cancer or DNA mutations. In this study, oxygen functional groups were introduced on activated carbons (ACs) by ozone treatment to enhance the cesium adsorption capacity. As the ozone treatment time increased, the oxygen content on the ACs surface increased. Subsequently, the electrostatic interaction between ACs and cesium enhanced, resulting in higher cesium ion adsorption efficiency across all samples. In particular, the sample treated with ozone for 7 minutes at an internal ozone concentration of 50000 ppm had roughly 12% greater oxygen functional group content and the highest cesium removal effectiveness (97.6%). Meanwhile, samples treated for 5 minutes showed a 0.3% cesium removal rate difference compared to those treated for 7 minutes, which was caused by the surface chemical similarity of the two samples due to the reactive characteristics of ozone gas. However, the cesium adsorption performance of ozonated activated carbon seems to be mainly influenced by the amount of oxygen functional groups introduced to the surface, although the specific surface area and pore structure of the activated carbon are also important.

Synovial sarcoma is an uncommon malignant soft tissue tumor which usually occurs in young-aged person, and frequently involves the lower extremities. Many authors recommended wide excision, adjuvant chemotherapy and radiation therapy. The proposed factors that affect the prognosis are age, size of tumor, site of tumor in the body, depth of tumor, histologic grade and method of treatment. The purpose of the study is to analyze the factors that affect the 5-year survival rate. We retrospectively evaluated 19 cases of synovial sarcoma treated in the Kosin University Medical Center from Jan. 1982 to Dec. 1994. The overall 5-year survival rate was 47.6% and the 5-year survival rates were significantly higher(P<0.05) in the group with smaller size of mass. The significantly lower 5-year survival rates were observed in the patient with deeply located lesion and with higher histologic grade. The 5-year survival rates were higher in the patients treated with wide excision than in the patients treated with amputation. But there was no significant difference between these groups. The adjuvant chemotherapy and radiotherapy were performed. In conclusion, we suggest that the better prognosis will be observed in the patients with smaller size of tumor mass, superficially located and lower histologic grade.

민영기,노태익 東亞大學校附設基礎科學硏究所 1999 基礎科學硏究論文集 Vol.16 No.1

Am-Be(10mCi) 및 Cf(5μCi)선원을 이용하여 흡수체에 대한 고속중성자의 전단면적을 측정하였다. 본 실험에서는 검출기로부터 흡수체의 물질과 중성자 선원간의 거리를 변화시켜 보았고, 흡수체 물질의 두께를 변화하여 투과율을 측정하였다. 또한, 정확한 투과율을 얻기 위해 Polyethylene 및 Paraffin으로 collimator를 제작하여 측정하였고, 이때 사용한 흡수체 물질은 H₂O, 금속(Au, Al, Cu, Pb)등을 사용하였다. 고속중성자 선원의 에너지는 각각 7.70MeV(Am-Be), 2.35MeV(Cf) 평균에너지였다. 실험에서 측정한 투과율로부터, 흡수체의 전단면적을 구하였고, ENDF값과 비교하여 보았다. 사용된 검출기는 2"×2" NE-213 유기액체 섬광검출기이다. We calculate total cross section of the fast neutron to the absorber using Am-Be(10mCi) and Cf(5μCi). Transmission rate were measured by varying the distance from absorber to the neutron source and the thickness of absorber. To accept transmission rate accurately, we design the collimator which made from Polyethylene and Paraffin. We use H₂O and verious metal(Au, Al, Cu, Pb) with absorber. Mean energy of the fast neutron sources are 7.70MeV(Am-Be), 2.35MeV(Cf) respectively. From the transmission rate measured by experiment, we calculate total cross section of absorber and compared with ENDF values. This experinent utilize the 2"×2" NE-213 organic liquid scintillation detector.

Recently it is known renal medullar will be play a important role of blood pressure control and pressure natriuresis. Renomedullary antihypertensive mechanism is activated by increasing perfusion pressure of kidney and can be inhibited by sympathetic nerve stimulation or blockade of nitric oxide(NO) formation. It is important to know what is affect on renal regional blood flow, especially renal medullary blood flow(MBF). For the purpose of investigating the effect of the renal sympathetic nerve on regional blood flow during infusion of blocking NO synthesis(by N^(ω)-nitro-L-arginine methylester:L-NAME) in spontaneous hypertensive rat(SHR) and Wistar rats normal control, Mean arterial pressure(MAP), total renal blood flow(TRBF), midcortical blood flow(CBF), inner medullary blood flow were measured in innervated or denervated renal sympathetic nerve group of SHR and Wister rats. All group that received the L-NAME were seen increasing MAP while TRBF, CBF and MBF decreased and the decrease of TRBF in SHR is more marked than in Wistar rat. In spite of increasing the MAP, MBF in all four group decreased, respectively C: 220 ± 3 U, 205 ± 2 U Wi : 215 ± 4 U, 165 ± 12 U Wd :218 ± 3 U, 170 ± 10 U Si :195 ± 4 U, 98 ± 15 U Sd : 200 ± 3 U, 120 ± 14 U, especially the most remarkable decrease about 50 % in SHR innervated group. Thus, according to these result, NO seems to maintain the MBF and the partial interaction between renal sympathetic nerve and NO in medullary blood flow can be suggested in innervated SHR.

The purpose of this study was to suggest the activation that Life Sport facilities affect sport for all with collection of various prior study thesis, related data. The results are as follows : Of quantity and quality, Sport for all facilities are insufficient to satisfy the nation's desire for life sport. Therefore, there were certain amounts of efforts to enlarge the gymnastics facilities in various aspects, but increased population of gymnastic activity van not be admitted to the variation. The facilities should be within accessible and available distance and site. For if the facility standard be stimulated by government and the private investment in order to balance between regional public facilities, the national financial aid of government is required. And, every individuals of nation must contribute positively to the expansion of Sport for all facilities so that gymnastics will be developed in consideration of individual returns.

교토대학 원자로 연구소의 46MeV 전자선형가속기를 사용하여 중성자 TOF 방법으로, 에너지 영역 0.003eV∼50keV의 ^161, 163Dy sample의 중성자 포획 단면적을 측정하였다. 본 실험에서 사용된 Bi_4Ge_3O_12(BGO) 섬광 검출기는 sample의 핵반응에서 나오는 즉발 포획 감마선 측정에 사용하였다. 이 검출기는 중성자 선원으로부터 거리 12.7±0.02m 위치에 12개의 블록으로 되어 있으며, sample에 포획되는 중성자 flux의 절대치를 구하기 위해 Sm(n, γ) 및 ^10B(n, αγ) 반응을 이용하였다. ^161, 163Dy에 대한 포획 단면적 측정결과는 ENDF/B-VI 결과와 비교하였다. The neutron capture cross sections of ^161, 162Dy has been measured in the energy region from 0.003eV 50keV by using the neutron time-of-flight(TOF) promptγmethod with a 46MeV electron linear accelerator at the Research Reactor Institute, Kyoto University. An assemble of twelve pieces of BGO scintillation detectors, which was placed at a distance of 12.7±0.02mm from the neutron source, was employed as a total energy absorption detector for the prompt capture gamma-ray measurement, to obtain the absolute capture cross section value. The sample of ^161, 163Dy is a form of metallic plate. An enriched boron sample was employed to monitor the neutron flux/spectrum of the TOF beam using the standard reference cross section of the ^10B(n, αγ) reaction. Previous measurements and evaluated data in ENDF/B-VI was compared with the present results.

Acute myocardial infarction after a bee sting is a very rare process. Among proposed mechanisms, vasospasm of the coronary artery ㅑs the most probable mechanism. Many mediators are included in the venom of wasps, and those mediators have vasoconstrictive properties and may constrict the coronary artery. Furthemore, those mediators have thrombogenic properties that lead to thrombogenesis in the coronary artery and aggravate myocardial ischemia. Epinephrine, commonly used in the management of anaphylactic shock, may further aggravate myocardial ischemia, We experienced two cases of acute myocardial infarction after a bee sting. In the first case, we could find no underlying abnormalities of the coronary vessel because the patient died during coronary angiography. In the second case, the electrocardiogram showed inferior wall myocardial infarction, but only mild stenosis of the right coronary artery was seen in coronary angiography.

The case of a patient with acute onset of flank pain is presented. Initial therapy was directed toward relief of pain believed to be caused by renal calculi. The flank pain did not responded to analgesics. An abdominal ultrasonogram showed that multiple hyperechogenic masses were in the parenchyma of both kidney, and an abdominal CT showed that multiple high-density masses, presumed to be angiomyolipomas, were located in both kidneys and in the perirenal hematoma around the left kidney. Vital signs were stable, and there was no evidence of anemia. On the seventh hospital day, angiographic tumor embolization was performed. Cases such as this should remind emergency physicians to carefully consider alternate diagnoses to renal calculi in patients with flank pain who have atypical clinical features or an atypical course.

Backgrounds: A retrospective study was performed to define objective radiologic parameters in diagnosing epiglottitis on soft-tissue lateral neck radiographic study. Methods: Parameters of soft-tissue structures(epiglottis width, third vertebral body width, ratio of epiglottic width to third vertebral body width) in 30 adult patients compared with those of age and sexmatched controls with foreign body in throat whose radiographic reading was normal. Results: Epiglottis width of more than 11mm, ratio of epiglottis width(EW) to the third vertebral body width(C3W) of more than 0.5 were, respectively, found to be 100% sensitive and specific in differentiating between patients with and without epiglottitis. Conclusion: These preliminary results suggest that EW/C3W ratio of more than 0.5, EW of more than 11mm, respectively, may be useful in the diagnosis of epiglottitis in adult patients.
