The purpose of this study was to identify the effects of phase 1 cardiac rehabilitation nursing care on cardiac rehabilitation knowledge, anxiety, and self-care behavior in patients with acture myocardial infarction. The study design was composed of a nonequivalent control group non-synchronized design and a non-equivalent control group post-test design. The subjects of the study consisted of thirty-four acute myocardial infarction patients hospitalized at a university hospital in Taegu between February 16, 1998 and May 12, 1998. the 34 research subjects were assigned to experimental( 17 patients ) and control( 17 patients ) groups. The phase 1 cardiac rehabilitation nursing care was composed of cardiac rehabilitation education taken from a rehabilitation manual and booklet, and participating in a progressive exercise program. After discharge, a phone interview was conducted in order to encourage the self-care behavior. The modified Knowledge Scale developed by Rahe et al.(1975) and translated into Korean by Hwang(1986), and the modified Self-Care Scale of exercise and diet based on Hickey et al.(1992), were used for data collection. Analysis of data was done by use of Chi-square test, t-test, Repeated measure ANOVA, Simple Main Effect, and Time contrast. The results of this study are as follows : 1. The first hypothesis, "The experimental group which received the phase 1 cardiac rehabilitation nursing care will have a higher level of knowledge than the control group", was supported(F=24.07, p=.000). 3. The third hypothesis, "The experimental group which received the phase 1 cardiac rehabilitation nursing care will have higher self-care behavior scores than the control group", was supported( t=-15.49, p=.000 ). From the above results, it can be concluded that phase 1 cardiac rehabilitation nursing care is an effective nursing intervention knowledge, reducing anxiety, and improving self-care behavior in patients with acute myocardial infarction.

This study is a descriptive survey conducted for the purpose of providing basic data to develop the effective nursing in interventions for Coronary Heart Disease patients. It was focused the relations between the type A behavior pattern and Health Locus of Control of them datd were collected through face-to-face interview with 55 CHD patients who were hospitalized at one of the general hospitals in Taegu city from May 11 to July 27, 1977. The instruments used for this studyy were the Jenkiness Activity Scale(Jenkins, 1979) and Health Locus of Control Scale(Wallstone & Wallston, 1978). Analysis of data was done by using of Person Correlation Coefficient, t-test, ANOVA, stepwise multiple regression and Cronbach with the SAS program. The results were as follows; 1. Total type A behavior pattern score was 67.2(total 88), job involvement /hard-driving subscale 35.9(total 47), sped subscale 12.8(total 16) and impatient subscale 19.09(total 25). The highest score of the type A pattern was the speed subscale 3.75 when it was transferred as a full mark 4. 2. When the total score of Health Locus of Control Scale of CHD was made 5, internal health locus control was the highest with 3.9, powerful others health locus control 3.6 and chance health locus control 3.0. 3. Women were significantly higher than men on total type A behavior pattern(p=.0453), job involvement/hard-driving subscale(p=.0492) and impatient subscale(p=.0460) according to general characteristics. Angina pectoris patients showed significantly higher than myocardial Infarction patients in total type A behavior pattern score(p=.0266), involvement/hard-driving subscale(p=.0365) and impatient subscale(p=.0185). 4. It was not significantly different for the Health Locus of Control Scale according to general characteristics. 5. Correlations between subscales of type A behavior pattern and subscales of Health Locus of Control showed that there were significantly positive correlation between internal health locus control and job-involvement/ hard-driving subscale(p=.0500), and between powerful others health locus control and important subscale(p=.0204). 6. The variances that can explain the causes of type A behavior pattern were systolic blood pressure 9%, quantity of smoking per day 9.6%, dyastolic blood pressure 8.6%, internal health locus control 6.2%, which accounted for 34.3% of the total variances. The following suggestions are made on the basis above results ; 1) The instrument that measures type A behavior pattern of CHD patient need to be modified and developed as an instrument that is applicable with Korea environment and easy to understand for subjects. 2) Replication of the research is need with nation wide samples. 3) Follow-up study for correlation between subscale of the type A behavior pattern and subscale of Health Locus of Control is needed. 4) Intervention program for CHD patients to reduce type A behavior pattern is to be developed.

BACKGROUND: Direct observation of healthcare workers is commonly used in hospitals to investigate hand hygiene compliance. However, the hand hygiene compliance rate may increase due to the Hawthorne effect, which is the modification of behavior simply because subjects become aware that they are being observed. The objective of this study was to investigate the occurrence of the Hawthorne effect when directly observing hand hygiene compliance in intensive care unit (ICU) healthcare personnel. METHODS: A total of 87 staff members from the coronary care unit and cardiac surgery ICU of a general hospital in Seoul were included in this study: 24 residents and interns, 55 nurses, and 8 nursing assistants. Both covert and overt observations, where subjects were either unaware or aware of any direct observation, were performed on separate occasions. RESULTS: A total of 1,052 covert and 1,336 overt observations were documented over 30 and 34 occasions, respectively. Overall hand hygiene compliance was significantly higher with overt observation than with covert observation (1,041/1,336, 77.9% vs. 659/1,052, 62.6%, P<0.001). The Hawthorne effect was present in all professions and behaviors, with the exception of nursing assistants, and prior to touching a patient. CONCLUSION: Direct observation of hand hygiene compliance was associated with the Hawthorne effect when observations were made overtly and this was likely to contribute to an overestimation of compliance rate.

PURPOSE: In the treatrnent of respiratory distress syndrome, Infants are often exposed to hyperoxia. It can generate oxygen free radical, damage to lung and bronchi, and inactivate pulmonary surfactant(PS). Antioxidant therapy in animal and human models has been tried to overcome this detrimental effects. We hypothesized that the addition of oxygen free radical such as hydrogen peroxide(H) could compromise surface active properties(SAP) of PS and that further addition of antioxidant such as catalaseR(CAT, Sigma chemical, St. Louis) could recover SAP. METHODS: We prepared combinations of mixtures with SurfactenR(S-TA, Tokyo Tanabe, Japan), H202 and CAT. 1)0.625mgPL(phospholipids)/ml or 1.25mgPL/ml S - TA and H202 were mixed to the final concentrations of 0.1 and 1mM H respectively, and incubated at 37C for one hour. 2) 0.625mgPL/rnl S - TA, H202 and CAT 10U were mixed to the final concentrations of lmM H202, and incubated at 37 degree C for one hour. We used Pulsating Bubble Surfactometer (Electronetics, NY) measure in vitro minimum and maximum surface tensions(ST) and area-surface tension relationship. RESULTS: 1) For 0.625mgPL/ml S-TA and 1mM H mixture minimum. ST after 5 min of pulsation increased significantly(P=0.007) and the area-surface tension curve was deformed. But they were comparable to control levels for 1.25mgPL/ml S-TA. 2) When CAT was added to 0.625mgPL/ml S-TA and 1mM H mixture, the resultant minimum ST after 5 min of pulsation dropped to the control levels with recovery of hysteresis curve(P=0.0001). CONCLUSION: PS could be inactivated by addition of high concentrations of H but SAP can be recovered either by increasing PS concentration or by further addition of antioxidant CAT. Therefore, we suggest that in case of suspected surfactant inactivation an increase in surfactant concentration or administration of antioxidant must be considered.

PURPOSE: Antenatal steroid(ANS) therapy in premature infants is an effective therapeutic strategy in reducing the incidence of respiratory distress syndrome, intraventricular hemorrhage, necrotizing enterocolitis, and patent ductus arteriosus. For premature infants to gain improved survival, adequate weight loss during early postnatal days and maintenance of electrolyte balance is important, however, it is uncertain that ANS affect them. We hypothesized that ANS augment fluid and electrolyte balance and dinical outcome of very low birth weight(VLBW) who had received restricted fluid regimen. METHODS: Mechanically ventilated VLBW infants who survived over 30 days were selected. We reviewed medical records to compare weight loss, urine output, electrolyte concentration, blood pressure during five days of life and clinical outcome between premature infants who received ANS(n=15) and who were not(n=58). RESULTS: Gestational age, birth weight were similar between two groups. Volume of administered fluid, urine output, and initial weight loss during first five days of life were similar, however, weight loss on postnatal day five were lower in study group than control group(p=.039). Blood pressure, serum sodium concentration, serum potassium concentration, and urine specific gravity were similar between two groups. Incidence of respiratory distress syndrome was lower in study group(20%) than control group(48%)(p=.041), however, incidence of sepsis were greater in study group(33%) than control group(7%)(p=.029). CONDUSION: ANS did not affect fluid and electrolyte balance of very low birth weight(VLBW) infants who had received restricted fluid regimen. ANS decreased the incidence of respiratory distress syndrome in this population, however, increased the incidence of sepsis.

Carcinosarcomas of the female genital tract have generally been regarded as a type of sarcoma. Recent studies, however, suggest the tumor may be more closely related to carcinoma and may represent metaplastic carcinoma in histogenesis. We analyzed clinicopathologic and immunohistochemical features of 10 carcinosarcomas to evaluate the relative importance of the carcinomatous and sarcomatous components in metastasis and recurrence. The primary tumor originated in the uterine body in seven cases, the uterine cervix in two and the ovary in one. Patient,s ages ranged from 54 to 71 years (mean, 64). The most common symptom of the uterine mass was vaginal bleeding. The median survival time was 21 months following diagnosis in five cases. Surgico-pathologic FIGO stages of five patients who received an operation were stage III and IV, but clinical FIGO stage of three patients (60%) among them were I. Lymphovascular invasions were identified in seven areas; five vascular invasion lesions showed the carcinomatous component alone, one the sarcomatous component alone, and remained one admixture of both components. Metastatic and recurrent lesions to the paraaortic lymph node, ovary, pelvic wall, or vaginal vault showed characteristically carcinomatous component only. Immunohistochemically, positive reactions for cytokeratin and epithelial membrane antigen were noted in the sarcomatous component of five cases. Vimentin positivity was detected in carcinomatous component of three cases. We conclude that the dominant element in carcinosarcomas of the female genital tract is the carcinomatous component. The survival rate of carcinosarcoma is extremely poor. The surgico-pathologic stage is better indicator of survival than the clinical stage. Immunohistochemical findings suggest that carcinosarcoma may represent a metaplastic carcinoma in histogenesis.

PURPOSE: This study was to investigate the relation among social support, drinking and smoking and to identify factors affecting high school students' smoking and drinking behaviors. METHODS: Data were collected from 361 high school students (182 students in 2 preparatory schools and 179 students in 2 vocational high schools) who were selected through convenient sampling. Data were analyzed using SPSS 11.5 for Windows. RESULTS: Factors affecting smoking behavior were drinking(OR=15.86. p<0.01), school type(R=11.82, p<0.01), school record(OR=46.62. p<0.001), pocket money (OR= 10.91. p<0.01) and brother's smoking (OR=9.09. p<0.05). Factors affecting drinking behavior were smoking(OR=8.32. p<0.01), school type(OR=2.53. p<0.01), school record(OR=2.35. p<0.01), pocket money(OR=2.01. p<0.05), father's educational background(OR=2.126. p<0.05), mother's drinking(OR= 1.83. p<0.05) and relationship with teacher (OR=2.44. p<0.01). CONCLUSION: The behaviors of drinking and smoking in high school students were highly correlated with each other. School record, school type, pocket money and family member's behaviors influenced student's behaviors. Further study is required to estimate the effect of drinking and smoking intervention programs according to student's characteristics such as school record, school type, pocket money management, and family members' influence.
