BACKGROUND AND OBJECTIVES: As previously reported, unstable angina is usually related to characteristic coronary artery lesion's morphology analyzed by coronary angiogram. This takes the form of an eccentrically placed convex stenosis with a narrow neck due to one or more overhanging edges or irregular, scalloped borders, or both. Although most studies were done for lesions with high degree stenosis(>50%), recent studies emphasized the role of vulnerability of plaque in acute coronary syndrome and even mild degree stenotic lesions may progress rapidly to evoke acute coronary syndrome. Therefore in this study, we analyzed the morphological characteristics of coronary artery lesions with mild degree stenosis as well as severe stenosis. MATERIALS AND METHODS: We conducted a retrospective study of 96 patients with angina pectoris (42 of stable patients and 54 of unstable patients) who underwent coronary angiography. Each lesions with 25% or greater diameter stenosis were categorized into simple and complex lesion(convex intraluminal obstruction with a narrow neck or irregular borders, diffuse irregularities, ulceration, thrombus). Calcification of coronary artery, extents of lesions were analyzed and stenosis grade and location were categorized by AHA classification. RESULTS: There were no significant differences between the stable angina and unstable angina in risk factors and vessel involvement, numbers of lesions, calcification and total obstruction. In morphologic analysis, complex lesions were more frequent in unstable angina than stable angina (49% vs 33%, p<0.05). The mean of percent diameter stenosis was not signigicantly different between two groups, but severe stenotic lesions with 90% or more stenosis were more frequent in unstable angina (34% vs 22%, p<0.05). Locations of involved vessels were similar between the angina groups. Complex lesions were distributed more frequent in RCA and simple lesions were more in LAD and LCX (p<0.05). CONCLUSIONS: The lesions with both complex morphology and severe degree stenosis are closely implicated in unstable angina.

This study was aimed to explore the relationship between the type of family system and the self-concept of kidney-transplantation recipients. 190 recipients were sampled from 3 general hospitals in Seoul and Kunggi-area, KOREA. Family Cohesion and Adaptability Evaluation Scale III (Olson et al., 1985) of the Circumplex Model (Olson et al., 1983) and Self-concept Test (Jeong, Won Sik, 1968) were used to collect the data. The data collected was analyses by the t-Test and ANOVA. It was found that there were no differences on recipients' self-concepts by types of family systems. But there were differences in recipients' self-concepts by family cohesion and adaptability levels. That is, the higher level of cohesion and adaptability, the higher the recipients' self-concepts. The type of family system and recipients' self-concept are related. So the recipients and the family of recipients must be included in subjects of medical and nursing care.

The purpose of this study was to provide fundamental data for nursing intervention by assessing self-esteem and quality of life(QL) in patients on hemodialysis and peritoneal dialysis. The subjects of this study were 60 patients on hemodialysis at H university medical center in Seoul and 56 patients on peritoneal dialysis at B company. The analysis was done by using t-test, ANOVA, Scheffe and Stepwise multiple regression. The results were as follows: 1. The average self-esteem score was signifi-cantly higher in patients on hemodialysis (27.98) than in patients on peritoneal dialysis (25.64). And there were no statistically significant differences between patients on hemodialysis(128.45) and patients on peritoneal dialysis(122.83) in the scores on QL. Among four factors of QL, hemodiaysis patients showed higher score than peritoneal dialysis patients in all factors. But, only family had statiscally significant differences. Also family showed the highest score in both groups, but psychomental showed the lowest score. 2. In patients on hemodialysis, self-esteem was significantly different by occupation(t=3.122, p=.003) and in patients on peritoneal dialysis by age(F=4.450, p=.007), education level(F=7.458, p=.001) and occupation (t=2.491, p=.017). Also in patients on hemodialysis, QL was significantly different by occupation(t=2.223, p=.033) and in patients on peritoneal dialysis by education level(F=4.007, p=.024), and occupation (t=2.806, p=.007).3. Self-esteem accounted for 36.3% of variance in QL and monthly income accounted for an additional 6.1% of QL in hemodialysis patients by means of stepwise multiple regression analysis. In peritoneal patients, self-esteem accounted for 65.1% and monthly income accounted for an additional 2.7% in QL.

The main purpose of this study was to characterize and classify families of KT recipients and to identify family adaptability and cohesion, as family function, by the Circumplex model. A Cross-sectional survey approach was employed for this research project. The data was collected by the questionnaire method in 3 general hospitals in Seoul and Kyonggi-do, Korea. The Family Adaptability and Cohesion Evaluation Scales III was used. By Convenient sampling, a total of 190 subjects (Male 117, Female 73) with an average age of 39.7 years (range: 18-62 yrs.) participated. The mean age at transplantation was 36.8 yrs. (SD: 9.4 yrs.). On an average, the patients had received transplants 39.9 months previously. The data was analyzed by percentage of frequency, t-test, and one-way ANOVA by the SPSS program. The results were as follows: 1. The mean family adaptability score was 30.26(SD: 6.6, range: 12-49) and the mean family cohesion score was 34.96(SD: 6.5, range: 15-48). 2. All of 16 distinct types of family system were identified. Among them, 'Flexibly connected types' (32 families, 16.8%) were the most common and 'chaotically disengaged types' (2 families, 1.1%) were the least common. 3. Dividing the 16 unit typology into 3 basic groups of types, 'Balanced types' composed 88 families (46.3%), 'Mid-range types' composed 76 families (40.0%), and 'extreme types' composed 26 families (13.7%). 4. The family adaptation differed according to age, education level, marital status, the diagnostic age of CRF, and level of recipient's perception of the family's importance. The family cohesion differed according to age, employment status, number of kid, and level of recipient's perception of the family's importance. In conclusion, by providing nursing intervention designed to increase family adaptability and cohesion, considering the socio-demographic factors of recipient and family, nurses may improve the recipient's family function and health, and also the recipient's health and quality of life.

Ultrasonographic and radiographic findings in 72 cases of pelvic masses which have been provedhistopathologically were analyzed. The results were as follows; 1. Among 72 cases, 28 cases were uterine massesand 44 cases were adnexal masses. 2. Pathologic accuracies of ultrasonographic diagnosis were 64.3% in uterinemasses, 70.5% in adnexal masses, and 68.1% in all pelvic masses. 3. Plain or IVP findings were not specific indiagnosis and showed secondary mass effects or functional disturbances. 4. Because of its high accuracy ofpathologic diagnosis and safety, ultrasonography can be regared as the most valuable and preferential study. Butin cases of cystic myomas, endometrioses, cystic missed abortions and huge masses, the accurate diagnoses weredifficult.
