Backgrounds and Objectives: Vascular dementia is a group of dementing disoders arising from various stroke syndrome. Among these. subcortical ischemic vascular dementia (SIVD) is regarded as a relatively distinct clinical entity. However, MRI patterns of SIVD are not homogenous. In some patients, lacunes are dominant, and in others, subcortical white matter changes are. This study was designed to compare risk factor profiles between SIVD with and without multiple lacunes. Methods: We divided 47 subjects (22 males, mean age. 68 years) recruited from VADAPET (Multicenter Trial For Evaluation Of The Changes In the PET Images Of Subcortical Vascular Dementia Patient) study into two groups one with more than 5 lacunes in deep gray matter (lacune group) and the other with 5 or less(non-lacune group) Clinical characteristics and laboratory findings of two groups were compared. Results: Nineteen of 47 patients (40%) belonged to the lacune group. The lacune and non-lacune groups d d not differ in the following variables: age, hypertension, diabetes mellitus, hyperlipidemia heart disease, history of stroke or TIA, history of trauma or major surgery, family history of hypertension stroke, or dementia, age at diagnosis of dementia, body mass index, white blood cell count, ESR, CRP, fibrinogen, hemoglobin A1C, total cholesterol. LDL cholesterol creatinine, proteinuria, glucosuria, and microhematuria. However, male sex, smoking alcohol. hemoglobin, and HDL cholesterol were possibly associated more with lacune group SIVD than with non-lacune group (p<0 1) Multivariate analyses revealed that smoking, hemoglobin, and HDL cholesterol were independent predictors of SIVD with multiple lacunes Conclusion: Our study suggests that SIVD with multiple lacunes may be significantly different in smoking habits hemoglobin, and HDL cholesterol from SIVD without multiple lacunes.

To evaluate the storage characteristics of pheasant meat products, contents of aerobic, anaerobic and food poisoning bacteria as well as VBN were measured during storage at various temperatures. 1. During the storage Escherichia coli and food poisoning bacteria including Salmonella, Shigella and Staphylococcus were not detected from any of the pheasant meat products. 2. Total plate counts of aerobic and anaerobic bacteria increased with storage temperature, showing more than 10^6 CFU/g of most pheasant meat products within 5~10 days of storage at 20℃ and 30℃. However, frank sausage, loin ham, pressed ham and salad showed less than 10^5 CFU/g in 20~30 days of storage at 20℃. 3. When stored at 10℃, smoked product, electric roasted product and pressed ham showed the bacterial counts of more than 10^4 CFU/g within 10 days of storage. Frank sausage, loin ham and salad, however, showed less than 10^3 CFU/g in 10 days of storage at 10℃. 4. VBN contents of smoked product, electric roasted product and frank sausage exceeded edible limit of 20 mg%, showing more than 40 mg% and 8 mg% within 5 days and 10 days, respectively, of storage at 10℃. In contrast, loin ham, pressed ham and salad had the VBN of less than 20 mg% in 10 days of storage at 10℃. In summary, while pheasant meat products in general appear to be prone to microbial growth, loin ham and salad are thought to have a longer storage period than others, showing about 10 days of preservation at 10℃. Products other than loin ham and salad are suggested to be stored frozen or refrigerated at below 10℃.

최가희,조성호 가톨릭대학교 사회과학연구소 2002 社會科學硏究 Vol.18 No.-

상담과정 및 성과에서 상담자 측면은 간과할 수 없는 중요한 부분임에서 불구하고 상담자 측면에 대한 연구는 부족한 실정이다. 따라서 본 연구는 상담과정 및 성과에서 상담자 측면에 관심을 가지고, 내담자에 대한 상담자의 지각, 즉 인상형성을 측정하는 척도를 개발하고자 하였다. 이를 위해 최가희(2002)가 사용한 주관적 인상형성 질문지와 치료적 인상형성 질문지를 토대로 59문항의 상담자 인상형성 척도를 제작하였고, 146명의 상담자를 대상으로 자료를 수집하였다. 상담자 인상형성 질문지에 대해 요인분석을 실시한 결과 7개의 요인이 추출되었는데, 7개의 요인은 각각 '긍정적 상담성과' '상담자의 촉진적 태도' '내담자 매력' '치료적 개입의 용이성' '내담자 정서적 안정성' '내담자 저항수준' '내담자 진실성'으로 명명되었다. 또한 내담자에 대한 인상형성 척도는 .94의 내적합치도를 보여 비교적 신뢰로운 것으로 나타났다. 본 연구의 결과는 내담자에 대한 상담자의 주관적인 인상형성과 치료적 인상형성이 구별된 요인으로 묶이는 것을 보여 주었고, 이론적으로만 구분되었던 주관적 인상형성과 치료적 인상형성을 경험적으로 지지해 주는 것이라 할 수 있다. 끝으로, 본 연구의 의의와 제한점, 그리고 추후 연구를 위한 제안들을 제시하였다. Although therapist plays an important role in counseling, research related to therapist has been insufficient. The purpose of this study is to develop Therapists' Impression-Formation Scale. For this. Therapist's Impression-Formation Scale was administered to 146 therapists. The scale is based on Personal Impression-Formation and Therapeutic Impression-Formation scales developed by Choi(2002). Seven factors were extracted from factor analysis of the scale, and they were named as positive therapy outcome, therapist's encouraging attitudes, client's attractiveness, easiness of therapeutic intervention, client's subjective well-being, client's resistance level, client's sincerity. Each factors reflect personal impression-formation and therapeutic impression-formation. The results of the study provide empirical evidence of the personal impression-formation and therapeutic impression-formation, and this scale can be useful on the research related to therapist. Finally, Limitations of this study and suggestion for the future study were discussed.

Arteriovenous fistula of uterus is a very rare cause of massive uterine bleeding. However, it is important to make a rapid and precise diagnosis when it does occur, because life-threatening massive vaginal bleeding may occasionally be a symptom of this disease. Uterine curettage or surgical trauma can cause vascular abnormalities, including pseudoaneurysms, acquired ateriovenous malformations, ateriovenous fistulas, and rupture of vessels. The diagnosis is made by angiography, and gray scale ultrasonography, color and duplex doppler ultrasonography, computed tomography, magnetic resonance imaging is helpful. Ultrasonography is the most commonly performed initial imaging examination for evaluation of abnormal uterine bleeding. Color and duplex Doppler US is an appropriate modality for the detection and diagnosis of uterine ateriovenous malformations and for follow-up after embolization. Transcatheter embolization has replaced hysterectomy as the treatment of choice in women wish to retain thier fertility. A case of arteriovenous malformation of the uterus which was diagnosed by ultrasonography. So reported this case with a brief review of the literature.

셀룰로오스에 방염성을 부여하기 위해 산화-환원 개시제인 Ce^??이온을 이용하여 브롬화비닐을 그라프시켰다. 일반적으로 그라프트율은 시간에 따라 증가하다가 정상 상태에 도달하고,단량체 농도에 비례하며 극대치를 갖는 개시제의 농도가 존재한다. 그라프트율의 증가에 따라 한계산소지수가 높아져 방염성을 보임을 알 수 있다. To impose the flame retardant properties on cellulose, vinyl bromide was grafted on cellulose by redox initiator Ce^??. Generally, graft yield increases according to graft reaction time but as time goes on it shows steady state, however, it keeps on increasing in proportion to monomer concentration and has an optimum initiator concentration. It was found that LOI was proportional to graft yield and grafted cellulose had flame retardant properties.

Purpose : This study was conducted to develop field triage, transportation, distribution, and prehospital care at a fire disaster by analyzing the victims of the fore that broke out at a bar in Incheon. Method : We analyzed the cases of the victims of a fire in Incheon in Oct. 1999. We determined the primary care hospital, the arrival time, the burn size, the outcome, and the injury type from the medical records, the concerned organ records, and interviews with concerned persons. Result : The total number of victims was 137: 56 prehospital deaths, 1 hospital death, and 80 survivals. The Pearson correlation coefficient between the burn size and the severity was -0.175. There were 121(89.6%) cases of inhalation injury, 59 (43.7%) cases of flame burns, 66 (48.9%) cases of hypoxic brain damage, and 16 (11.9%) cases involving other types of injury. Conclusion : The causes of death of the fire victims were inhalation injury and hypoxic brain damage due to CO poisoning and other toxic inhalants. We propose the use of a simple triage and rapid treatment(START) system and a reassessment the delayed category in fire disasters.

Staphylococcus lugdunensis is a coagulase-negative staphylococcus (CNS) that is commonly found on the human perineal skin. Contrary to other CNS, S. lugdunensis is a rare contaminant in cultures and has the potential to cause clinically significant infections, including infective endocarditis. Infective endocarditis due to S. lugdunensis have been known to resemble endocarditis due to S. aureus because of its aggressive clinical course and high mortality. We report a case of infective endocarditis caused by S. lugdunensis in a 21-year-old woman. She was cured of the infection with surgical and antibiotic therapy. S. lugdunensis에 의한 감염성 심내막염은 국내에서보고가 없었던 매우 드물지만 다양한 합병증과 높은 사망률을 보이는 감염증이다. 저자들은 S. lugdunensis가 수술적 치료와 항생제 치료로 완치된 감염성 심내막염 1예를 경험하였기에 문헌고찰과 함께 보고하는 바이다.
