PURPOSE: The purpose of this study was to develop an instrument to assess bullying of nurses, and test the validity and reliability of the instrument. METHODS: The initial thirty items of WPBN-TI were identified through a review of the literature on types bullying related to nursing and in-depth interviews with 14 nurses who experienced bullying at work. Sixteen items were developed through 2 content validity tests by 9 experts and 10 nurses. The final WPBN-TI instrument was evaluated by 458 nurses from five general hospitals in the Incheon metropolitan area. SPSS 18.0 program was used to assess the instrument based on internal consistency reliability, construct validity, and criterion validity. RESULTS: WPBN-TI consisted of 16 items with three distinct factors (verbal and nonverbal bullying, work-related bullying, and external threats), which explained 60.3% of the total variance. The convergent validity and determinant validity for WPBN-TI were 100.0%, 89.7%, respectively. Known-groups validity of WPBN-TI was proven through the mean difference between subjective perception of bullying. The satisfied criterion validity for WPBN-TI was more than .70. The reliability of WPBN-TI was Cronbach's alpha of .91. CONCLUSIONS: WPBN-TI with high validity and reliability is suitable to determine types of bullying in nursing workplace.

PURPOSE: The purposes of this study were to explore nurse' bullying experiences according to demographic characteristics and to identify effects of workplace bullying and job stress on turnover intention in hospital nurses. METHODS: One hundred sixty-one graduate students working as nurses were recruited. The collected data were analyzed using descriptive statistics, t-test, ANOVA, Pearson correlation coefficient, and Stepwise multiple regression with PASW 18.0. RESULTS: Results show that 23.0% of the nurses interviewed had experienced bullying in the workplace within the last six months and 19.4% had been bullied during the entire employment period. Bullying perpetrators included nurses (52.9%), physicians (23.0%), and patients (17.8%). Bully nurses consisted of senior nurses (63.0%), managers or supervisors (29.6%), colleagues (3.7%), and junior nurses (3.7%). Job turnover intention in hospital nurses was significantly correlated with workplace bullying (r=.20, p=.012) and job stress (r=.37, p<.001). The most significant predictors influencing the turnover intention of hospital nurses were job stress, age, and bullying in total career and these factors accounted for 21.0% of the variance. CONCLUSION: Job stress and bullying significantly influence turnover intention. Therefore, educational programs should be developed and implemented to prevent workplace bullying.

BACKGROUND: The flowers of Inula japonica (Inulae Flos) have long been used in traditional medicine for the treatment of inflammatory diseases. In the present study, we investigated the anti-inflammatory properties of Inulae Flos Extract (IFE). METHODS: The anti-inflammatory effects of IFE against nitric oxide (NO), PGE2, TNF-alpha, and IL-6 release, as well as NF-kappa B and MAP kinase activation were evaluated in RAW 264.7 cells. RESULTS: IFE inhibited the production of NO and the expression of inducible nitric oxide synthase (iNOS) in LPS-stimulated RAW264.7 cells. In addition, IFE reduced the release of pro-inflammatory cytokines, such as TNF-alpha and IL-6. Furthermore, IFE inhibited the NF-kappa B activation induced by LPS, which was associated with the abrogation of I kappa B-alpha degradation and subsequent decreases in nuclear p65 and p50 levels. Moreover, the phosphorylation of ERK, JNK, and p38 MAP kinases in LPS-stimulated RAW 264.7 cells was suppressed by IFE in a dose-dependent manner. CONCLUSION: These results suggest that the anti-inflammation activities of IFE might be attributed to the inhibition of NO, iNOS and cytokine expression through the down-regulation of NF-kappa B activation via suppression of I kappa B alpha and MAP kinase phosphorylation in macrophages.

BACKGROUND: Our aim was to assess the validity of a semi-quantitative food frequency questionnaire (FFQ) by comparison with the 3-day diet record (DR) in patients with type 2 diabetes. METHODS: Eighty five type 2 diabetic patients (aged 33 to 70 years) from the Korean National Diabetes Program (KNDP) completed 3-day DR and FFQ. The FFQ was designed to reflect the eating pattern of Korean type 2 diabetic patients, and was based on the 2003 Korean National Health and Nutrition Examination Survey. The FFQ consists of 85 food items and 12 food groups. The validity of FFQ was assessed by comparison with the 3-day DR. RESULTS: The mean age was 49 +/- 10 years. Clinical characteristic including body weight, diabetic duration, and HbA1c were not different from the total cohort subjects (n = 1,478). There were no significant differences in the mean intake of protein, fat and calcium estimated by the FFQ and the 3-day DR. Energy and carbohydrate estimated by the FFQ were higher than those estimated by the 3-day DR. The correlation coefficient was highest for energy (r = 0.740; P < 0.00) and lowest for iron (r = 0.269; P < 0.05). The Kappa values for energy, carbohydrate, protein, fat and calcium were 0.54, 0.37, 0.36, 0.46, and 0.19, respectively. CONCLUSION: The FFQ is a reasonable instrument for assessing the intake of most macronutrients in Korean type 2 diabetes, although careful consideration is required for the food groups and nutrients for which the FFQ had low validity.
