Purpose: This study aimed to investigate the associations of sleep, dietary behaviors and physical activity with quality of life among shift-work nurses. Methods: For this cross-sectional descriptive study, data were collected from 191 shift-work nurses in a tertiary hospital. Multiple linear regression analysis was used to identify the relationships among variables. Results: The levels of sleep quality, dietary behaviors and physical activity were low. Factors associated with quality of life among shift-work nurses included sleep disturbance (B=-0.16, ${\beta}=-0.26$, p<.001), dietary behaviors (B=0.28, ${\beta}=0.24$, p<.001), and physical activity (B=0.05, ${\beta}=0.19$, p<.001). The strongest factor was sleep disturbance. Conclusion: In order to improve quality of life among shift-work nurses, it is significant to encourage and maintain health behaviors such as sleep, dietary behaviors and physical activity. Under the circumstances where shift-work cannot be avoided, personal efforts made by nurses to establish their own living standards for positive health behaviors will benefit their quality of life.

This study was conducted to examine the effect of dietary n-3/n-6 fatty acid (FA) ratio on in vitro dry matter digestibility (IVDMD), fermentation indices and FA profile. Rice bran was mixed with oil sources (cotton seed oil and linseed oil) to make the diets at 0.02, 0.29 and 0.61 of dietary n-3/n-6 FA ratio. These diets (0.5g) were placed into the incubation bottles with 40 ml of anaerobic culture medium, which contained rumen fluid and Van Soest medium at 1:2 ratio. Five replicates of each diet and two blanks were incubated at $39^{\circ}C$ for 48 hours. After incubation, the incubated contents were centrifuged. The residues were freeze-dried for DMD and FA analyses. The supernatant was used for pH, $NH_3-N$ and volatile fatty acid analyses. The concentrations of lactate (p<0.001) and iso-valerate (p<0.001) decreased linearly with increasing dietary n-3/n-6 FA ratio, but acetate concentration (p=0.056) and the ratio of acetate to propionate (p=0.005) was increased linearly. The concentrations of n-3, n-6 FA and the ratio of n-3/n-6 FA in residues increased (p<0.001) linearly with increasing dietary n-3/n-6 FA ratio, but C18:1n-9 FA concentration was decreased (p<0.001) linearly. With these results, it could affect fermentation characteristics and FA profile of rumen content by dietary n-3/n-6 FA ratio.

This study was conducted to explore the degree of female nursing student's dietary behavior, self esteem, dietary self-efficacy, life stress and the factors influencing dietary behavior of those surveyed. A total of 422 female nursing students in B, C city were surveyed. The data were collected between May 15 and 30 of 2016 and analyzed by a t-test, ANOVA, Pearson's correlation coefficients, and multiple regression analysis using SPSS WIN/21.0. The mean score of dietary behavior was $3.01{\pm}0.49$. In addition, there were significant differences in dietary behavior with respect to grade(F=4.823, p=0.008), residential type(F=6.067, p<.001), academic grade(F=3.907, p=0.021), health status(F=7.975, p<0.001), and degree of health concern(F=4.189, p=0.016). Moreover, there were negative correlations between dietary behavior and self esteem(r=-.238, p<0.001), and dietary self-efficacy(r=-0.438, p<0.001), while there was a positive correlation between dietary behavior and life stress(r=0.194, p<0.001). Regression analysis showed 26.7% of variance in female nursing student's dietary behavior can be explained by dietary self-efficacy, life stress, residental type, and degree of health concern. A follow-up survey investigating various factors influencing female nursing student's dietary behavior is needed and increased dietary behavior education and programs are required.

Objective: This study was conducted to investigate the effect of dietary onion (Allium cepa) extract (OE) supplementation on growth performance, apparent total tract retention (ATTR), blood profile, carcass characteristics and meat quality in broilers. Methods: Four hundred male broiler chicks (Ross 308, 3-d old) were randomly allocated to four dietary treatments for 28 d feeding trial. Each treatment has five replications with 20 birds each. Four dietary treatments were designated according to the OE supplementation levels (0 as control, 5, 7.5, and 10 g of OE per kg of basal diet respectively). On d 28, a total of 20 birds from each treatment were subjected for ATTR, serum biochemical assay, carcass characteristic and organ weight measurement. Results: Overall weight gain of OE 7.5 g/kg group was higher (p = 0.04) than control group. The ATTRs of dietary energy (p<0.01) and ether extract (p = 0.04) linearly increased with increasing levels of dietary OE. However, no difference in ATTR of dry matter and crude protein was evident. Furthermore, serum IgG concentration increased linearly (p<0.01) and quadratically (p = 0.03) with increasing OE supplementation. No differences in carcass dressing weight and amount of abdominal fat by treatments were observed. Also, the weight of organ including immune organ was not different among the treatments. The TBARS values of 10 d stored breast meat decreased linearly (p<0.01) and quadratically (p<0.01) with increasing dietary OE levels. The meat color was also affected, with lower (p<0.01) redness score in meats from OE supplemented groups. This study showed that dietary OE improved broiler weight gain presumably by increasing feed intake and ATTR of both energy and ether extract. The dietary OE increased serum IgG level and meat anti-oxidation capacity. Conclusion: This study implies that the recommended level of dietary OE supplementation could be beneficial for improving broiler performance and meat quality.

This study assessed the beauty care behavior and the dietary attitudes, eating behaviors, and dietary quality related to beauty care in accordance with the level of interest in beauty care by examining 558 female high school subjects in the Incheon area. The study aimed to identify the interest in beauty care on the part of adolescent girls that impacts their dietary life and provide basic data for nutrition education forming desirable dietary habits. The interest in beauty care on the part of female high school students is relevant to dietary life and dietary attitude, with the high-level interest group attempting to use diet foods more frequently and attempting weight control because of their low satisfaction with their body type. On the other hand, a high level of interest in appearance failed to lead to the practice of a varied and balanced dietary life. Therefore, nutritional education is necessary to avoid a high level of interest in beauty care, leading to an incorrect perception of body shape and excessive weight control. Furthermore, nutrition education is necessary to link interest in appearance to the beauty of a healthy body based on nutritional balance by connecting the interest in appearance to a varied and balanced dietary life that goes beyond the category of practice.
