The purpose of this study was to identify the effect of body positioning on $PaO_2$, $SpO_2$, systolic blood pressure, diastolic blood pressure, pulse, and respiration(above all defined physiologic index), of patients with unilateral lung disease. The subjects for this study were eleven patients admitted to I.C.U. of K.H.M.C. with a diagnosis of unilateral lung disease confirmed by chest X-ray and the attending doctor, from January 30th. to April 20th. 1999. A quasi-experimental repeated-measures cross-over design was used to compare three body positions(semi-Fowler's, lateral decubitus with good lung dependent, and lateral decubitus with diseased lung dependent). Each subject spent 30 minutes in semi-Fowler's position and 2 hours in good lung dependent position and diseased lung dependent position. Starting in the semi-Fowler's position, then in the lateral position with the good lung dependent or the diseased lung dependent as assigned in random order. Thirty minutes after each positioning, arterial blood sample was analyzed. Measurements of all physiologic index were recorded at the specified intervals(0, 30, 60 90, and 120 minutes) in good lung dependent and diseased lung dependent position. Statistical comparison of $PaO_2$ value was done using the Wilcoxon Signed Rank Test, and Multivariate repeated-measures analysis of variance was performed to analyse the within-subject effect of two dependent position for 2 hours on the five dependent variables: (1) $PaO_2$ (2) $SpO_2$ (3) systolic blood pressure (4) diastolic blood pressure (5) pulse. The results obtained were as follows: 1. The $PaO_2$ value in the good lung dependent position was significantly higher than the $PaO_2$ value in the diseased lung dependent position(Z=-2.8451, p=.002). 2. The $PaO_2$ value in the good lung dependent position was significantly higher than the $PaO_2$ value in the semi-Fowler's position (Z=-2.6673, p=.003). 3. The difference between the $PaO_2$ value in the semi-Fowler's position and the $PaO_2$ value in the diseased lung dependent position was not significant(Z=-1.2448, p=.10). 4. There were no statistically significance in the trends of physiologic index in the good lung dependent position and the diseased lung dependent position. From the results, it may be concluded that the good lung dependent position is the most effective position for patients with unilateral lung disease that improve oxygenation. Identification of positioning over time may be need further studies.

Purpose: This descriptive survey was aimed to investigate the ICU nurses' job stress, the way of coping, and the turnover intention and to identify the correlation among them. Methods: A 58 items-questionnaire composed of 7 sub-dimensions revised by Park, J. S. (2003) was used to measure the ICU nurses' job stress, and an questionnaire by Han, J. S. and Oh, G. S. (1990) which has 34 items from 6 sub-dimensions were used to measure the ICU nurses' way of coping. To figure out the ICU nurses' turnover intention, a 3 items-questionnaire used. A total of 456 nurses were participated in the study. Results: The participants' job stress was 2.86(4-point scale), and the way of stress coping was 2.27. Job stress had a positive correlation with the way of coping (r=.134, p=.004) and the turnover intention. The 54.1% of nurses addressed that they had some level of turnover intention. The turnover intention had a significant difference according to job stress(t=-2.041, p=.042), the type of hospital (${\chi}^2=8.052$, p=.005) and the total number of hospital beds (${\chi}^2=9.232$, p=.010). Conclusion: The findings of the study illustrated that the ICU nurses had at least moderate-high level of stress. The subjects' job stress showed a positive correlation with the way of coping and the turnover intention. These findings demonstrate necessity to develop an intervention for ICU nurses' stress management.
