This study was designed to investigate the effects of the progressive muscle relaxation on behavioral states and emotional reactions of adolescent athletes. The participants were 167 adolescent male soccer players aged between 12 and 18 who were junior or high school students in Seoul. Ninety-three of them were assigned to the experimental group, while seventy-four to the control group. The experimental group was treated by 10 sessions (20 min./session) of Jacobson's progressive muscle relaxation for two weeks, while the control group was not treated. The self and observer reported behavioral states, general stress by visual analogue scale, physical symptoms of stress, athletic stress, state anxiety, depression, self-esteem were measured before and after two weeks of the progressive muscle relaxation. The results were as follows ; 1. The self and observer reported behavioral states were significantly decreased in the experimental group compared with the control group. 2. The general stress and the gastrointestinal symptoms of stress were significantly decreased in the experimental group compared with the control group. No significant difference on athletic stress was found between the two groups. The depression and the state anxiety were significantly decreased in the experimental group compared with the control group. The self-esteem was significantly increased in the experimental group compared with the control group. 3. The influential factors on behavioral state of adolescent male athlete were depression and state anxiety. The accelerating factor on behavioral state change after the progressive muscle relaxation was state anxiety. These results are suggested that the progressive muscle relaxation could be effective in stabilizing behavioral state, decreasing general stress, gastrointestinal symptoms of stress, depression, state anxiety, in increasing self-esteem of adolescent male athletes. And the behavioral state change after the progressive muscle relaxation was influenced by state anxiety.

The purpose of the study was to investigate two areas as a basis for providing an educational program for pulmonary rehabilitation. A) the learning needs about chronic obstructive pulmonary disease in patients with chronic obstructive pulmonary disease and B) the perception of nurses of the same learning needs. The subjects consisted of 57 patients, with chronic obstructive pulmonary disease, at the general hospital in Seoul and 71 nurses, who were working in the medical ward. Data was obtained from a "learning need" questionnaire between October 29 and November 19, '99. Data was analyzed using SAS program for t-test, ANOVA, Scheff test. The result were as follows: 1. The learning needs of the nurses(mean 4.36 +/- .38) were higher than those of the patients (mean 3.56 +/- .83). (t=6.78, P=.001) 2. The highest ranked patient education needs were as follows ; a)"how to control dyspnea", b)"cause for activating dyspnea", and c)"how to minimize the necessity of oxygen in daily living": and nurses' learning needs were ; a)"how to cope with the risk situation", b)"management after discharge", and c)"how to control dyspnea". 3. In the patient group, those who had a college degree or higher education and paid their own hospital expenses were higher in the learning needs. According to the above results, we should consider an educational program which is realistic and effective for patients by evaluating the items the patients really want to learn about and how much they know about the evaluated items.

This study was designed to investigate the effects of information by using cartoon on preoperative anxiety of children following tonsillectomy. The subjects were 30 children aged between 7 and 12 who were hospitalized at C university hospital for undergoing tonsillectomy from December 20, 1996 to August 14, 1997. Sixteen of them were assigned to the experimental group, while fourteen subjects to the control group. The data were collected through preoperative state anxiety, pulse rate, pain before and after giving information by using cartoon. The results were as follows : 1. Preoperative state anxiety increased in both groups(P=0.0348). No significant difference found between experimental and control group. But preoperative anxiety in experimental group was apt to increase less than that in the control group. 2. Pulse rate didn't make significant difference within and between groups. 3. Pain increased in both groups(P=0.0001). No significant difference found between experimental and control group. 4. Experimental group between the aged 7 and 9 decreased preoperative state anxiety, but experimental group between the aged 10 and 12 increased preoperative state anxiety after treatment(P=0.0298). These findings may indicate that the information by using cartoon is effective in children between the aged 7 and 12.

BACKGROUND: The purpose of this study was to examine the frequency and characteristics of needlestick/sharps injuries (NSIs) in nursing students in Korea. METHODS: The study was based on a survey of questionnaires completed by 341 nursing students who had sustained at least one NSI during clinical practice in hospitals. RESULTS: The NSI incidence rate was 36.4%. Approximately half of the students reported two to four NSIs. Most (90.2%) of the NSIs occurred on the fingertips and were caused by a hollow-bore needle (46.8%) or lancet (45.8%). Some students were exposed to used needles contaminated with unknown pathogens (37.3%), HBs Ag (2.3%), Venereal Disease Research Laboratory (VDRL) (0.8%), or HIV (0.6%). Students cited the reason for injury as carelessness, inexperience, hastiness, or recapping. Almost two-thirds of students who reported having experienced an NSI knew about post-exposure treatment. However, only one-third of the students with NSIs completed an official report. CONCLUSION: Korean nursing students lack knowledge about injury prevention, report procedures, and treatment after NSI. A revised educational approach with emphasis on occupational risk, skill development, and injury reporting is necessary to prevent NSI and to ensure that students obtain post-exposure prophylaxis.

PURPOSE: The aim of this study was to evaluate whether T1-201 reinjection distinguishes viable from non-viable myocardium in patients with reverse redistribution after acute myocardial infarction. MATERIALS AND METHODS: We studied 42 patients with acute myocardial infarction (age, 55+/-12 years). Eighteen (43%) out of 42 showed reverse redistribution on dipyridamole stress-4 hour redistribution T1-201 single photon emission computed tomography (SPECT). T1-201 reinjection was performed at 24 hours. Reverse redistribution was defined as worsening of perfusion defect at 4 hour delayed scan. All patients underwent follow-up echocardiography in 4 months to assess regional wall motion improvement. T1-201 uptake on reinjection images were analyzed for the prediction of myocardial wall motion improvement. RESULTS: Of 36 segments with reverse redistribution, 17 segments showed normal wall motion on echocardiography, while 19 segments showed all motion abnormalities. Of 19 the segments with reverse redistribution, 11 (58%) showed enhanced uptake after 24 hour reinjection. Myocardial wall motion was improved in 10 of 11 segments (90%) with enhanced uptake on reinjection. Wall motion improvement was not seen in 5 of 8 segments (63%) without enhanced thallium uptake. When myocardial viability was assessed by the uptake on reinjection image, nine of 10 segments (90%) with normal or mildly decreased uptake showed improved wall motion. Wall motion was not improved in 5 of 9 segments (56%) with severely decreased uptake. CONCLUSION: In patients with acute myocardial ifarction, T1-201 reinjection imaging on myocardial segments with reverse redistribution has a high positive predictive value in the assessment of myocardial viability.

Ecologic studies are widely used in all fields of public health on account of accesibility of data. However, two problems related to these studies have been brought up. The first is ecological fallacy occurred in the course of interpreting the ecologic level of exposure-disease associations into individual level. The second is exposure isclassification which leads to serious bias. Nevertheless there is few methodologic study dealing joint effects of the two problems in ecologic study. This study was conducted to suggest an ecologic model not having an ecologic fallacy due to model linkage failure and a methodology for correcting the misclassification bias due to exposure-confounder misclassification. Finally, we suggest a criteria for the ecologic model selection. Main results are as follows: 1. A linear ecologic regression model has a serious ecological fallacy due to model linkage failure and the misclassification bias due to the exposure-confounder misclassification. 2. An interaction ecologic regression model has no ecological fallacy due to model linkage failure, but it is affected seriously by the exposure misclassification. However misclassification bias could be removed mathematically if the information related to the misclassification was known. 3. A log-linear ecologic regression model has an ecological fallacy due to model linkage failure. It is seriously biased as the individual risk ratio are increased, but relatively less affected by the exposure misclassification than interaction ecologic regression model. 4. One of the two ecologic regression model-interaction ecologic regression model and log-linear ecologic regression model- would be selected according to the information of individual risk ratio and exposure misclassification. But using a linear ecologic regression model should be avoided in any circumstance. The above results are only valid in case that there is no other source of ecological fallacy except model linkage failure. Also exposure and confounder are independent each other, measured binary, and having nondifferential misclassification. Since the above assumptions are somewhat strong in considering the real situations of ecologic studies, it is necessary to extend the scope of this study.

PURPOSE: This study was done to investigate the degree of self-care, family support and depression, and relationship among these variables for elder with diabetes mellitus. METHOD: Participants were 202 diabetic patients, 65 years or over, living in Seoul, Korea. Data were collected using the self-care tool for diabetic patients by Kim (1996), the family support tool for diabetic patients by Park (1984), and Korea\' s BDI scale by Lee (1995). RESULTS: Of the patients, 43.1% showed HbA1c levels than higher 7%. The highest mean score was for self-care for medication compliance, and the lowest for blood glucose testing compliance. Factors affecting self-care were employment, education, HbA1c level, diabetic self-care education and complications. Factors affecting family support were living with family, diabetic self-care education, hospitalization and complications. Factors affecting depression were gender, living with family and complications. All of these factors were significant. Patients experiencing depression were 16.8% of patients. There was a significant positive correlation between self-care and family support, and significant negative correlations between self-care and depression, and family support and depression. CONCLUSION: For more effective management of diabetes mellitus in elders, improvement in self-care compliance, and family support are needed

PURPOSE: This study was done to provide information on issues of nursing core competencies needed in the fields of nursing practice for graduates in nursing, from the perspective of nursing managers, and to make suggestion for improving nursing education programs. METHODS: Ten nursing managers participated in this study. They were in charge of clinical nursing education in the fields of nursing practice. Data were collected using focus group interviews and analyzed with the content analysis methodology of Downe - Wamboldt's. RESULTS: Six types of nursing core competency - therapeutic nursing competency, professional nursing competency, administrative nursing competency, humanistic nursing competency, relational nursing competency, and personal nursing competency - were identified as nursing core competencies needed in the fields of nursing practice for graduates in nursing. CONCLUSION: Results of the study show important evidence for decision-making about nursing curriculum revision based on nursing core competency, both in the classroom and in nursing practice areas. These results should contribute to the development of evaluation indicators for nursing students or new nurses. Further research is required to measure degree of nursing core competency in graduates of nursing and to identify the effect of competency-based education for improving nursing core competency.

PURPOSE: This research was conducted to identify major factors that influence competency for nursing students in basic nursing skills. METHOD: Data were collected by questionnaires from 290 first year students in one college of nursing. The instrument tools included motivation for admission to nursing, concern about fundamentals of nursing, perceived importance of fundamentals of nursing, level of active participation in fundamentals of nursing, number of times to use open Lab, Lab class satisfaction, self-efficacy, self-evaluation and student attitude. RESULTS: There was no significant correlation between competency in basic nursing skills and motivation for admission to nursing, concern about fundamentals of nursing, perceived importance of fundamentals of nursing, or number of times to use open Lab. Competency in basic nursing skill in these students showed a significantly positive correlation to Lab class satisfaction, self-efficacy, self-evaluation, student attitude and level of active participation in fundamentals of nursing. The major factors that influenced competency in basic nursing skills for nursing students were student attitude, self-efficacy and number of times to use open Lab. These factors explained 15.5% of the variance in competency. CONCLUSION: Basic nursing skill practice education programs should be developed to improve self-efficacy and active participation.
