Structural Relationships among Job Embeddedness, Emotional Intelligence, Social Support and Turnover Intention of Nurses / 간호행정학회지

PURPOSE: This study was done to elicit basic data for effective human resource management by identifying the relationships among job embeddedness, emotional intelligence, social support, and the turnover intention of Nurses. METHODS: Research design was to build a hypothetical causal model between variables and to verify its fitness. The sample for this study was 283 nurses with careers of more than 6 months in one hospital of more than 800 beds located in Seoul. They agreed in writing and this study was approved by the Institutional Review Board. Data were analyzed using SPSS 18.0 and AMOS 18.0 program. RESULTS: Differences in general characteristics for the variables were significant for age, marital status, education, work experience, job title, income, and department. Job embeddedness, emotional intelligence and social support were significantly correlated to turnover intention. Job embeddedness to emotional intelligence and social support showed positive effects and a negative effect to turnover intention. Emotional intelligence to turnover intention showed a positive effect, but social support was not significant. CONCLUSION: Organizations should provide ways to minimize voluntary turnover of a competent workforce and demonstrate their competency. Also it should develop training and management programs to effectively utilize emotional intelligence.

The Effect of Coronary Stenting on Ventricular Activation Time in Coronary Artery Disease

BACKGROUND AND OBJECTIVES: The ventricular activation time (VAT) is increased in both ventricular hypertrophy and bundle branch block. It is also known that the VAT is increased in myocardial ischemia due to the development of depolarization abnormality. However, little is known about the changes in the VAT on body surface electrocardiography following coronary stenting in patients with ischemic heart disease. The purpose of this study was to evaluate the clinical significance of VAT following coronary stenting by assessing the changes in the VAT during the 6 months following coronary stenting in patients with ischemic heart disease. SUBJECTS AND METHODS: The VAT was measured in 92 patients who had underdone coronary stenting due to of significant coronary artery stenosis on coronary angiography. The electrocardiography was recorded with a high paper speed at pre-stenting, immediate after and at 1 and 6 months after coronary stenting. RESULTS: The VAT was significantly decreased during the 6 month follow-up following coronary stenting (pre-stenting ; 45.9 +/-5.9 msec, immediate after stenting ; 38.5+/-2.7 msec, after 1 month ; 38.8+/-2.8 msec and after 6 months ; 38.8+/-2.5 msec, p<0.05). The VAT dispersion was significantly decreased during the 6 month follow-up following coronary stenting in the patients with one vessel disease (p<0.05), but not with two vessels disease. CONCLUSION: Coronary stenting significantly decreased the VAT during the 6 month follow-up. We would conclude that coronary stenting relieves depolarization abnormalities caused by myocardial ischemia, and improves the intraventricular conduction velocity. However, further studies are needed to assess the usefulness of VAT in evaluating myocardial ischemia.

The Effect of Muscle Relaxation Therapy on Mood State and Job Stress of Clinical Nurses / 성인간호학회지

PURPOSE: This study is to identify the effects of muscle relaxation therapy on mood state and job stress of clinical nurses, finally to purpose the bases of nursing intervention to increased of work efficiency and job satisfaction. METHOD: The research design was a nonequivalent control group pretest-posttest design. The subjects were 50 clinical nurses (23 for experimental group), who were working for 1-5 years in medical and surgical ward from the 2 C-University medical center in Seoul. This study was conducted from May 12 to July 25, 2000. The muscle relaxation therapy was performed 5 weeks to experimental group. The experi-mental group participated in the muscle relaxation training sessions for 20minutes twice a week during five weeks. The level of job stress was measured by nurses occupational stress scale. The level of Psychological response was measured by Profile of mood state. The data was analyzed using descriptive statistics, x2-test, t-test, paired t-test. RESULT: The results of this study were as follows: The experimental group who received the muscle relaxation therapy showed more reduction of job stress level (t=1.35, p=0.038) and profile of mood state level (t=2.27, p=0.027) after therapy than those in control group. CONCLUSION: This study reveals that the muscle relaxation therapy is effective in reduction of nurse's job stress and promotion of mood state. So the researcher thinks that it is useful in reduction of job stress and increased of job satisfaction in hospital.

Heart Rate Recovery in Coronary Artery Disease and the Changes of Exercise Parameters after Coronary Stenting

BACKGROUND AND OBJECTIVES: The recovery of the normal heart rate immediately after exercise is a function of vagal reactivation. An attenuated heart rate recovery during the first minute after graded exercise is believed to be a marker of reduced parasympathetic activity and has been proven to be an independent predictor of overall mortality. However, the clinical significance of an abnormal heart rate recovery in coronary artery disease and the changes in the exercise parameters after coronary stenting have not been fully evaluated. Subjects and Methods: The study population included 53 patients with a significant coronary artery stenosis and 25 subjects with a normal coronary artery. All underwent a treadmill exercise test prior to coronary angiography. The differences in the heart rate recovery and the Duke treadmill score between two groups were investigated. After coronary stenting, changes in the exercise parameters were evaluated during the follow-up treadmill exercise test in 22 coronary artery disease patients. RESULTS: The frequencies of abnormal heart rate recovery (12% vs 38.3%, p=0.014) and a moderate to high risk Duke treadmill score (4% vs 21.3%, p=0.034) were significantly higher in the coronary artery disease group. The frequencies of these parameters were also significantly higher in the multivessel disease group than the single vessel disease group. After coronary stenting, most of the exercise parameters showed no significant changes but the Duke treadmill score improved significantly (p=0.038). CONCLUSION: The frequency of abnormal heart rate recovery was significantly higher in the coronary artery disease group. The Duke treadmill score was significantly improved and is thought to be a useful follow up parameter after coronary stenting.
