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.

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.

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.

Turnip yellow mosaic virus (TYMV) is a spherical plant virus that has a single 6.3 kb positive strand RNA as a genome. Previously, we have made the recombinant TYMV construct containing a 0.7 kb eGFP gene or a 1.8 kb GUS gene. The genomic RNAs from these constructs were efficiently encapsidated. To examine in more detail whether size constraint exists for replication and packaging of TYMV, we have inserted into the TY-GUS an extra sequence derived from either eGFP or GUS. We also made a recombinant containing RNA1 sequence of Flock house virus. These TYMV recombinants were introduced into Nicotiana benthamiana leaves by agroinfiltration. Northern blot analysis of the viral RNAs in the agroinfiltrated leaves showed that the genomic RNA band from the recombinant TYMV became weaker as longer sequence was inserted. The result also showed that the efficiency of genomic RNA encapsidation decreased sharply when an extra sequence of 2.2 kb or more was inserted. In contrast, the recombinant subgenomic RNA containing an extra sequence of up to 3.2 kb was efficiently encapsidated. Overall, these results show that size constraint exists for replication and encapsidation of TYMV RNA.

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.

BACKGROUND/AIMS: Entecavir is a synthetic nucleoside analogue, cyclopentyl guanine nucleoside, which has a potent antiviral effect and the least viral breakthrough in hepatitis B virus (HBV) replication. Entecavir has been available in Korea since 2007 but there are few reports on its effects. The aim of this study was to evaluate the virological response (VR) and biochemical response (BR) to entecavir in HBV patients at 3, 6 and 9 months after treatment with entecavir. MATERIALS AND METHODS: Thirty-three chronic hepatitis B patients who took entecavir for at least 9 months were enrolled. We investigated VR and BR by retrospectively reviewing medical records. Patients who satisfied the following criteria were chosen: 1) initial alanine aminotransferase (ALT) levels = 1.5upper limit of normal (ULN) and 2) initial HBV DNA levels = 5 log10 copies/ml. We measured ALT levels every 3 months until month 9. HBV DNA was measured every 2 or 3 months by polymerase chain reaction (PCR) method. RESULTS: Most patients taking entecavir showed good BR (ALT < 40 IU/L). The BR rates were 61%, 73% and 67% at months 3, 6 and 9, respectively. VR (HBV DNA < 5 log(10) copies/ml or 2 log lower than initial HBV DNA) rates were 82%, 91% and 91% at months 3, 6 and 9, respectively. Undetectable HBV DNA (HBV DNA < 4 log(10) copies/ml) rates were 49%, 73% and 85% at months 3, 6 and 9, respectively. Two patients presented with virological breakthrough without adverse effects until month 9. CONCLUSIONS: Entecavir showed good BR and VR from month 3 and these effects continued through the 9-month observation period. This suggests that entecavir is also a good choice for the first line treatment of chronic hepatitis B (CHB). Further studies are needed to determine the long-term efficacy and drug resistance of entecavir in Korean CHB patients.

PURPOSE: This study was conducted to examine the effects of a multicultural course on nursing students' multicultural acceptability and competency. METHODS: The research design for this study was a non-equivalent control group, non-synchronized pre- and post-test. The experimental group (n=28) took 13 weeks of the multicultural course, while the control group (n=28) received only regular classes over the same period. Pre- and post-tests were done to identify the effects of the program. The data were collected using self-administered questionnaires and analyzed using the PASW 18.0 program. RESULTS: All indices of multicultural acceptability and competency in the experimental group were significantly higher than that of control group after the program, except for two: universality (a measure of multicultural acceptability) and multicultural awareness (a measure of multicultural competency). CONCLUSION: These results suggest that the multicultural course was effective in elevating the level of multicultural acceptability and competency among nursing students.

Turnip yellow mosaic virus (TYMV) is a non-enveloped icosahedral virus composed of 20 kDa single coat proteins. In this study, we modified the TYMV coat protein (CP) ORF by inserting an oligonucleotide linker corresponding to T7, HSV, Tat, (Arg)9, or (RxR)4 peptide at the 5'-end of the CP ORF and examined its effect on replication, RNA packaging, and virion assembly. The results showed that the constructs containing (Arg)9 and (RxR)4 sequences were barely capable of replication. The TYMV constructs containing T7 and Tat peptide produced virions that co-migrated with wild-type virions. However, the insertion of T7 and Tat sequences impaired genomic RNA (gRNA) accumulation and packaging, respectively. When only the CP gene was expressed, CPs with (Arg)9 or (RxR)4 successfully produced virus-like particles whose mobility was comparable to that of wild type. In the case of CP having a HSV tag, the virion band was not detected, although a sufficient amount of CP was produced. This indicates that CP with the HSV tag failed to assemble into virions. Overall, the results suggest that TYMV replication, RNA packaging and virion assembly are strongly influenced by the insertion sequence.
