The Effects of Nursing Information and Short-Term Relaxation Technique on Anxiety Level and Physiologic Data in Endoscopy Patients / 성인간호학회지

This study was designed to test the effects of nursing intervention on anxiety level, on the change of physiologic data of the patients undergoing endoscopy. The subjects for the study consisted of 50 hospitalized patients on internal medicine unit in Chonbuk University Hospital during the period between August 1. 1996 and October 3. 1996. Sample were selected according to reestablished criteria. 25 patients were enrolled in experimental group and the other 25 patients were enrolled inthe control group. Experimental group was nursing information and short-term relaxation technique used visual imagination did control group did not given. State anxiety level was measured, using the tool developed by Spielberger(1972) and modified by Kim and Shin(1978), and physiologic data were monitored by blood pressure, pulse rate, serum cortisol level. Data analysis was done by X2-test, t-test, paired t-test, repeated measure of ANOVA using the SAS program. The results were as follows: 1. The first hypothesis that 'the experimental group given nursing information and short-term relaxation technique will be less change of state anxiety level before and after endoscopy than the control group without nursing intervention' was accepted (Experimental group t=-3.65, p=.831; Control group t=-6.34, p=.002). 2. The second hypothesis that 'The experimental group given nursing information and short-term relaxation technique will be loss change of systolic blood pressure before and after endoscopy than the control group without nursing intervention' was accepted(Experimental group F=1.346, p=.12; Control group F=4.590 p=.02). 3. The third hypothesis that 'The experimental group given nursing information and short-term relaxation technique will be loss change of diastolic blood pressure before and after endoscopy than the control group without nursing intervention' was rejected(Experimental group F=.210, p=.76; Control group F=.180 p=.89). 4. The fourth hypothesis that 'The experimental group given nursing information and short-term relaxation technique will be loss change of pulse rate before and after endoscopy than the control group without nursing intervention' was accepted(Experimental group F=.952, p=.17; Control group f=3.997 p=.04). 5. The fifth hypothesis that 'The experimental group given nursing information and short-term relaxation technique will be loss change of serum cortisol level before and after endoscopy than the control group without nursing intervention' was accepted(Experimental group t=1.184, p=.124; Control group t=2.042 p=.034). As seen above, it was concluded that the nursing information and short-term relaxation Technique were effective to reduce anxiety level, physiologic and serum cortisol change in patients undergoing endoscopy. So furthermore, we should continue the Experimental study for testing effectiveness of nursing intervention of anxiety every setting and the results of the study is sure to be useful in clinical field.

A Study on Working Environment and Health Status of Workers in Some Dyeing Factories / 대한산업의학회지

This study was carried out to evaluated the actual conditions of working environment and health status of workers and search more effective health management method of workers in some dyeing factories. This study was conducted from April 1 to October 30, 1992, for 426 workers in two dyeing factories and an electric wire making factories. Among 324 workers in two dyeing factories, 57.5% were male and 42.5% were female. Most of the engaged workers had less than 2 years of working carrier and aged 30 years or below. The used chemical substances exceeding 1 ton per a month were sodium hydroxide(NaOH), hydrogen peroxide(H2O2), sodium chlorite(NaClO2), sodium sulfate(Ma2SO4), sodium carbonate(Na2CO3), and sodium hydrosulfite(Na2S2O4). The used chemical dyes exceeding 100kg per a month were suncion blue H-ERD, levafix brilliant red E-4BA, suncion yellow E-3G, and remazol black B. As the allowable exposure time by governmental threshold limit valuses to industrial noise levels in 90 dBA for 8 hours. Average noise levels of the individual plants were ranged from 75 to 95 dB (A). The TLV for total cotton dust in 2.0mg/m3. Average cotton-dust concentration in these working environmental air were ranging from 0.2-1.3mg/m3. The TLV chlorine, acetic acid and formic acid are 1 ppm, 10 ppm & 5ppm, respectively. The range of chlorine, and acetic and formic acid concentration in these working environmental air were detected 0.2-1.6 ppm and at trace level. The accident by chemical substances and dyes was not found on these working environment. From the physical examination and Todai Health Index scores results, there was no significant correlation between the used chemical substances and the diseases, such as bronchial asthma, other hyperreactive respiratory diseases and contact dermatitis. It was suggested that long term survey should be performed to detect the occupational health problem on these working environment.
