The effects of quality grade and storage time on physicochemical, sensory properties and microbial population of Hanwoo striploin beef were investigated. After a total of 30 Hanwoo beef were slaughtered, the cold carcasses were graded by official meat grader at 24 h postmortem. The carcasses were categorized into five groups (quality grade 1++, 1+, 1, 2, and 3) and were vacuum-packaged and stored. The samples were kept for 1, 4, 6, 8, 11, 13, 15, 18, 20, 22 and 25 d for analyses. As the quality grade was increased, moisture, protein and ash contents decreased (p<0.05). Higher quality grade corresponded with higher fat contents. The shear force values decreased with increasing quality grade and showed decreases sharply during the first 4 d (p<0.05). pH, water holding capacity, cooking loss, and volatile basic nitrogen for grade 1++ groups were lower than for grade 3 (p<0.05). CIE L∗ and b∗ values increased as increased quality grade (p<0.05). Meat color decreased until 13 d and fluctuated after 15 d of storage (p<0.05). Regarding the sensory scores, higher quality grade corresponded with higher juiciness, tenderness, flavor, fatty and palatability scores (p<0.05). Generally, increased storage time for 15 d improved sensory scores attributes. Results indicate that a high quality grade could positively influence physicochemical and sensory properties. © 2015 Korean Society for Food Science of Animal Recources.

Background: Blood volume may profoundly affect the isolation of microorganisms in blood cultures. The effect of blood volume in standard anaerobic bottles of the BacT/ALERT 3D system was investigated. Methods: Adult patients who visited the emergency department and referred for blood culture (n = 824) were enrolled from June to September 2013. Two sets of blood cultures were obtained from each patient. One set consisted of 5 mL that was collected in a standard aerobic bottle (SA5), 5 mL that was collected in a standard anaerobic bottle (SN5), and 10 mL that was collected in a standard anaerobic bottle (SN10). The growth of clinically significant pathogens and the time to detection (TTD) were compared between the SN5 and SN10 samples. Results: Increasing the volume of blood collected from 5 to 10 mL yielded a 14.7% improvement in the isolation of microorganisms. There was a statistically significant difference in the isolation of pathogens (14 vs. 30, P = 0.023) between the SN5 and SN10 samples. Grampositive microorganisms were detected earlier in the SN10 samples than the SN5 samples (P = 0.052). The mean TTD of all pathogens was 13.5 h for the SN5 samples and 12.9 h for the SN10 samples (P = 0.099).Conclusion: Increased blood volume in the SN bottle yielded a significantly higher pathogen detection rate. However, there was no difference in the frequency of earlier detection or TTD between the SN5 and SN10 samples. © 2015 Kim et al.

Purpose: This study was done to develop a reproductive health program to improve reproductive health of women immigrants. Methods: The participants in the study were 58 immigrant women who lived in Vietnam, China, Philippines, or Cambodia before marriage. They were assigned to the experiment group (n= 29) or the control group (n= 29). The reproductive health program for this study consisted of reproductive health education, health counseling, phone monitoring, and emotional support based on Cox (1982)'s Interaction Model of Client Health Behavior and was implemented for four weeks. Results: There were significant differences in reproductive health knowledge (t= 9.78, p<.001), reproductive health attitude (t= 6.59, p<.001), and reproductive health behavior (t= 5.11, p<.001) within and between groups after the reproductive health program. But there were no significant differences in clinical indicators between the two groups. Conclusion: The results of this study indicate the that reproductive health program for the women immigrants is effective in terms of reproductive health knowledge, reproductive health attitude and reproductive health behaviors. Therefore, nurses in public and private facilities, such as multicultural centers and public health centers in each community, should develop strategies to expand and provide reproductive health programs for women immigrants. © 2014 Korean Society of Nursing Science.

This study was conducted to compare the physicochemical traits of dry-cured hams made from two different three-way crossbred pigs: Yorkshire×Landrace×Duroc (YLD) and Yorkshire×Berkshire×Duroc (YBD). Animals were slaughtered at a live weight of 110 to 120 kg and cooled at 0°C for 24 h in a chilling room, the ham portion of the carcasses were cut and processed by dry-curing for physico-chemical analyses. While the moisture and crude protein contents of dry-cured ham were higher in YLD than in YBD, crude fat and ash content were higher in YBD (p<0.05). The salt contents of ham from YBD were higher than those from YLD (p<0.05). YBD ham samples showed a higher L∗ and b∗ values than those from YLD, while YBD ham showed lower avalue (p<0.05). Thiobarbituric acid reactive substances (TBARS) and volatile basic nitrogen (VBN) values of YLD hams were lower than those of YBD samples (p<0.05). Hardness, gumminess, chewiness, and shear force values of YBD ham were higher than those of YLD sample (p<0.05). Saltiness was significantly higher in YBD ham than in YLD samples (p<0.05). YLD ham displayed a superior quality than YBD. Considering the meat quality parameters of two-way crossbred ham, YLD hams could be more suitable for the production of dry-cured products.

Aims and objectives: To develop an objective instrument to measure nurses' entry-level knowledge of and skills in evidence-based practice, and to evaluate the validity and reliability of the instrument. Background: To promote evidence-based practice in nursing, nurses should initially receive education about evidence-based practice knowledge and learn the skills, and this should be followed by measurement with an instrument that was developed to evaluate the extent to which they are prepared to use evidence-based practice knowledge and skills. Although some self-report instruments have been developed to measure evidence-based practice in nursing, an objective instrument to evaluate nurses' evidence-based practice knowledge and skills is not available at present. Design: A methodological study. Methods: This study was conducted in two stages: the instrument development and its psychometric evaluation, including its validity and reliability. An instrument, 'Knowledge and Skills of Evidence-based Nursing,' was developed. Content validity was assessed by five experts in evidence-based nursing, and the construct validity was evaluated by the known-groups method. Reliability was examined with internal consistency reliability and inter-rater reliability. Results: A content validity index >0·80 was achieved. For construct validity, there were statistically significant differences between the evidence-based practice and nonevidence-based practice groups in total scores and in the scores on each subscale of the Knowledge and Skills of Evidence-based Nursing. Cronbach's alpha was 0·96, and the inter-rater reliability was excellent. Conclusions: The Knowledge and Skills of Evidence-based Nursing is a valid and reliable instrument for objectively assessing nurses' evidence-based practice knowledge and skills; it is quick to complete and to score the answers. Relevance to clinical practice: Because the Knowledge and Skills of Evidence-based Nursing objectively assesses nurses' evidence-based practice knowledge and skills, it can be used to examine the effects of evidence-based practice education. Moreover, the Knowledge and Skills of Evidence-based Nursing may contribute to the promotion of evidence-based practice projects in clinical settings because it can measure the extent to which nurses are prepared to use their evidence-based practice knowledge and skills. © 2015 John Wiley & Sons Ltd.
