PURPOSE: This study was conducted to identify correlations in hospital nurses' work environment, emotional labor and happiness index to provide basic resources for nurses' happiness at work. METHODS: Resources were gathered from 291 nurses who agreed to participate. Random sampling of nurses in nine hospitals in G-do was done between July 15 and August 14, 2014. Data were analyzed using chi2 tests, independent t-test, One-way ANOVA, Pearson correlation coefficients and multiple hierarchical regression with SPSS/WIN 18.0. RESULTS: Mean scores (scale of 5) were nurses' work environment, 2.81, emotional labor, 3.24, and happiness index, 2.94. There were significant differences on the happiness index for: age, marriage, children, clinical experience, position, payment, and future work plans and a negative correlation between work environment and emotional labor, emotional labor and happiness index but a positive correlation between happiness index and work environment. Happiness index was influenced by work environment, emotional labor, future work plans. Explanatory power of these variables was 26%. CONCLUSION: Based on the findings of this study, so it is necessary to improve the work environment and reduce the frequency of emotional labor in order to increase the happiness index of hospital nurses.

BACKGROUND: Portable devices for measuring peak expiratory flow(PEF) are now of proved value in the diagnosis and management of asthma and many lightweight PEF meters have become available. However, it is necessary to determine whether peak expiratory flow rate(PEFR) measurements measured with peak flowmeters is accurate and reproducible for clinical application. The aim of the present study is to define accuracy, agreement, and precision of mini-Wright peak flow meter(MPFM) against standard pneumotachygraph. METHODS: The lung function tests by standard pneumotachygraph and PEFR measurement by MPFM were performed in a random order for 2 hours in 22 normal and 17 asthmatic subjects and also were performed for 3 successive days in 22 normals. RESULTS: The PEFR measured with MPFM was significantly related to the PEFR and FEV1 measured with standard pneumotachygraph in normal and asthmatics(for PEFR, r=0.92 p<0.001; for FEV1, r=0.78 ; p<0.001). The accuracy of MPFM was within 10%(limits of accuracy recommeded by NAEP) in all the subjects or 22 normal, mean difference from standard pneumotachygraph being I 6.5L/min(percentage of difference being 2.90%) or 1 0.6L/min(percentage of difference being 1.75%), respectively. According to the method proposed by Bland and Altman, the 95% limits of the distribution of differences between MPFM and standard pneumotachygraph after correction of PEFR using our regression equation were +38.2 and -71.5L/min in all the subjects or -20.49~ + 9.49L/min in 22 normal and was similar to the intraindividual agreements for 3 successive days in normal. There was no statistically significant difference of PEFR measured with MPFM and standard pneumotachygraph among three days(p>0.05) and the coefficient of variation(2.4 1.2%) of PEFR measured with MPFM was significantly lower than that( 5.2 3.5%) with standard pneurnotachygraph in normal (p<0.05). CONCLUSION: This results suggest that the MPFM was as accurate and reproducible as standard pneumotachygraph for monitoring of PEFR in the asthmatic subjects.

PURPOSE: The aim of study was to identify the effects of exercise on the relief of low back pain in patients on absolute bed rest after TAE. METHOD: A nonequivalent control group pretest-posttest design research design was used. The participants were 43 patients who had received TAE in a university hospital; patients in the experimental group (21) received both exercise therapy and general post-op nursing care and in the control group (22) only the latter. The exercise program used in this study was modified from exercise for post CABG to exercise for post TAE, which deflect the movement of thigh in which the catheter was inserted, the lumbar region of the back and pelvis. RESULTS: First, Low back pain scores in the experimental group were lower than the control group. Second, The first dose of analgesics in the experimental group was delayed compared to the control group. Third, There was no significant difference in bleeding complications between the experimental group control groups. CONCLUSION: The results suggest that the exercise program used in this study is effective for relief of low back pain in patients on absolute bed rest after TAE.

PURPOSE: Exercise-induced bronchospasm (EIB) is widely prevalent in asthmatic patients. Recently, eosinophilic airway inflammation and atopy (defined as skin sensitivity to common aeroallergens) are considered to be a important factors in the pathogenesis of asthma. Thus we studied to find out the effect of atopy and airway eosinophilic inflammation on exercise- induced bronchospasm. METHODS: We followed up the cases of 132 mild asthmatics for 2 years. On their first visit, skin prick tests, with 29 common allergens including dust mites antigen, and sputum induction were performed. And 3 days later, methacholine challenge was done. 24 hours after methacholine challenge, treadmill test was performed and the positive EIB was defined as a 15% reduction or more in FEV1 from baseline after exercise. RESULTS: EIB was observed in 54 (40.9%) of 132 asthmatic subjects. There was no significant difference in atopy between EIB positive and EIB negative asthmatics. Eosinophil and eosinophil cationic protein in induced sputum were significantly higher in EIB positive asthmatics. We also found the significant correlation between bronchial responsiveness (BR) index and maximal % fall in FEV1. CONCLUSION: The severity of bronchospasm evoked by exercise was more closely related to eosinophilic airway inflammation and airway hyperresponsiveness to methacholine than atopy.

Maspin is a recently described gene with tumor suppressor activity. The gene product is a 42 kD protein with homology to the serpin family of protease inhibitors and may play a role as an inhibitor of tumor cell invasion. The prior observation that invasive breast cancers and their metastases showed decreased maspin protein expression by immunostaining supports this speculation. However, the role of maspin in breast cancer progression has not been studied in detail. We, therefore, studied maspin protein expression in a series of hyperplasia, atypical ductal hyperplasia, intraductal carcinoma and invasive carcinomas. Immunohistochemical staining (IHC) for maspin was performed on paraffin sections of 136 breast specimens using a commercially available monoclonal antibody. Among the 106 cases studied were 36 moderate/florid ductal hyperplasia, 11 atypical ductal hyperplasia (ADH), 29 intraductal carcinoma (IDC) (4 low grade, 13 intermediate grade, 12 high grade) and 30 invasive ductal carcinomas. Thirty cases of normal breast were also studied as control group. IHC stains were scored using a semiquantitative scoring system. The mean IHC scores for maspin for normal, moderate/florid hyperplasia, atypical ductal hyperplasia, intraductal carcinoma, and invasive carcinoma were 5.51 1.30, 7.36 0.72, 3.82 1.60, 4.48 2.69, 3.97 3.30, respectively. These scores for each category were statistically significant (p<0.05), except between ADH and IDC. Maspin protein expression was increased in most cases of moderate/florid hyperplasia, while maspin expression was more heterogeneous in ADH and IDC. In high grade IDC, maspin protein expression was stronger than low and intermediate grade IDC, and this suggests the possibility of a compensatory cellular response against the forces driving further tumor progression. Two thirds of invasive ductal carcinomas expressed maspin protein weakly and focally. All metastatic carcinomas of lymph nodes were negative for maspin. It is possible that high grade IDC with strong maspin expression may represent a subset less likely to progress to invasive cancer. This speculation merits investigation in clinical outcome studies.

PURPOSE: The purpose of this study was to investigate Seoul teacher's satisfaction with and needs for health examination and health promotion programs. METHODS: The participants were 3,186 teachers in Seoul. Data were collected through an on-line survey system from November 16 to December 7, 2008. Collected data were analyzed by descriptive statistics, t-test, ANOVA, and Scheffe's test using PASW 18.0 program. RESULTS: Teacher's satisfaction with teacher health examination was low and needs for detailed tests of cancer and vocal cord disorders were high. Teacher's satisfaction with teacher health promotion programs was low and needs for stress management, exercise and vocal cord protection program were high. CONCLUSION: Vocal cord disorders should be included in teacher health examination and vocal cord protection program should be provided for teacher's health promotion. Stress management and exercise program should also be provided for teacher's health promotion.

BACKGROUND: Stunned myocardium may be mediated by intracellular Ca2+ overloading or oxygen derived-free radicals. Halothane and propofol have been shown to block Ca2+ channels. Propofol is also known to have antioxidant properties. The present study was aimed to investigate the effects of anesthetics on recovery of postischemic, reperfused myocardium in open-chest dogs. Incidence of ventricular arrhythmia upon ischemia and reperfusion was also determined. METHODS: Forty dogs were subjected to 15 min occlusion of left anterior descending coronary artery (LAD) followed by 3 hr reperfusion during halothane (n=10), fentanyl (n=12), or propofol plus fentanyl (n=11) anesthesia. Regional contractile function was assessed using percent systolic shortening (%SS), the preload recruitable stroke work slope (Mw), and peak systolic intramyocardial pressure (IMPs). Diastolic function was evaluated using time constant for isovolumic intramyocardial pressure decline of left ventricle (IMP-tau) and percent post-systolic shortening (%PSS). RESULTS: %SS in the halothane, fentanyl, and propofol-fentanyl groups was similar at 3 hours of reperfusion (58%, 60%, and 55% of baseline value, respectively). Moreover, Mw recovered to the baseline values in the early reperfusion period in all three groups. However, IMP-tau was significantly prolonged in the halothane group throughout the 3 hour reperfusion period, whereas it remained unchanged in the fentanyl and propofol-fentanyl groups. Coronary occlusion was associated with 9, 33, and 0% mortality rate due to ventricular fibrillation upon ischemia and reperfusion in the halothane, fentanyl, and propofol-fentanyl groups, respectively. CONCLUSION: These findings indicate that halothane, but not fentanyl and propofol- fentanyl, impairs myocardial relaxation, while recovery pattern of contractile function do not differ among three groups, and that halothane and propofol reduce reperfusion arrhythmia in the canine model of myocardial stunning.

PURPOSE: Atopic dermatitis is the most common chronic inflammatory skin disease in children. However, the role of allergy in the pathogenesis of atopic dermatitis is still controversial. The purpose of this study is to investigate the effects of antigen sensitization and development of respiratory allergy disease on severity of atopic dermatitis. METHODS: 211 children with atopic dermatitis were monitored for 2-3 years and classified into three groups: mild, moderate, severe. The severity of atopic dermatitis was compared with antigen sensitization identified by MAST CLA Korea Panel and development of respiratory allergy disease; such as asthma and allergic rhinitis. RESULTS: The frequency of mild, moderate, severe atopic dermatitis was respectively, 38.4%, 33.6%, 28.0%. Food sensitization was significantly higher in patients under 4 years old and aeroallergen sensitization was higher in patients above 5 years old. There was a good correlation between the severity of atopic dermatitis and food sensitization but not in aeroallergen. There was no significant association the severity of atopic dermatitis and development of respiratory allergy disease. CONCLUSION: This result suggests that the sensitization to food allergen is associated with the severity of atopic dermatitis, but sensitization to aeroallergen and development of respiratory allergy disease are not correlated. The restriction of sensitized diets might be helpful in management of atopic dermatitis.

OBJECTIVE: To measure the performance of a hospital enterprise resource planning (ERP) system and suggest various system improvements. METHODS: A survey based on a 5-point Likert scale questionnaire and an exclusive interview was administered to 102 employees with a one-year experience of using an ERP system at one university hospital. In order to analyze the factors affecting the ERP system performance, multiple regression analysis and Chi-square test were conducted. RESULTS: All three examined variables-system quality, information quality and integration of hospital information resources-affected the ERP system performance positively. However, the system quality variable had the lowest mean score indicating that the ERP system was difficult to understand for many users. User characteristics were not significantly associated with information quality satisfaction. CONCLUSION: On the basis of the study results, we recommended some suggestions to improve the ERP system performance. In order to reduce users' dissatisfaction with the new system, hospitals should publicize the needs of the ERP system for the employees, design more effective training programs, and provide more decision-supporting information for managers.
