The effect of dehydrated food waste product (DFWP) inclusion in diets of Taiwan native chickens on the growth performance, carcass traits, clinical blood chemistry and nutrient digestibility was investigated with 320 male Taishi Native Chickens (Taishi No. 13). They were randomly allocated into four levels of DFWP inclusion (0, 5, 10, or 20%) treatment. Each treatment had 80 chickens with four replicates. At 15 weeks of age, 8 chickens were selected from each group for the nutrient digestibility trial. The results showed that body weight gain during the 0 to 4 week period decreased as the feed intake and feed conversion rate (FCR) increased linearly with increasing level of DFWP inclusion. During the 4 to 8 week period, greater body weight gains were recorded for the birds on the 5% DFWP inclusion level than for the control (p<0.05). During 8 to16 weeks, the feed intake and FCR increased linearly (p<0.05). Interestingly too, results of the carcass analysis showed that DFWP inclusion up to 20% in the diet significantly decreased the relative abdominal fat weight but increased the relative proventriculus and gizzard weights of the birds. However, other carcass parameters, meat quality and sensory scores were not significantly influenced by the dietary DFWP inclusion levels (p>0.05). Higher serum aspartate aminotransferase, ${\gamma}$-glutamyltransferase activity and crude protein digestibility, and lower gross energy digestibility were observed in the 20% DFWP group compared to the control (p<0.05). Dietary DFWP inclusion was inappropriate during the 0 to 4 week period. During 4 to 8 weeks, there was no adverse effect on chicken performance in the 20% group. There was no disadvantage on carcass properties and in the meat panel test. This result would not affect consumer determination.
Background: Given that there are many Iranian women who have never had a Pap smear, this study was designed to develop and validate a measurement tool based on the Protection Motivation Theory to assess factors influencing the Iranian women's intention to perform first Pap testing. Materials and Methods: In this psychometric research, to determine the Content Validity Index (CVI) and the Content Validity Ratio (CVR), a panel of experts (n=10) reviewed scale items. Reliability was estimated through the Intraclass Correlation Coefficient (n=30) and internal consistency (n=240). Also, factor analysis (exploratory and conformity) was performed on the data of the sample women who had never had a Pap smear test (n=240). Results: A 26-item questionnaire was developed. The CVI and CVR scores of the scale were 0.89 and 0.90, respectively. Exploratory factor analysis loaded a 26-item with seven factors questionnaire (perceived vulnerability and severity, fear, response costs, response efficacy, self-efficacy, and protection motivation (or intention)) that jointly accounted for 72.76% of the observed variance. Confirmatory factor analysis indicated a good fit for the data. Internal consistency (range 0.70-0.93) and test-retest reliability (range 0.72-0.96) of sub-scales were acceptable. Conclusions: This study showed that the designed instrument was a valid and reliable tool for measuring the factors influencing the women's intention to perform their first Pap testing.
The purpose of this study was to investigate the effects of the home environment of young children on their language and the quality of peer competence. The current study hypothesized that when the home environment of young children is desirable, the young children would be more likely to develop better language skills, which in turn, predict greater peer competence and lower levels of aggression and withdrawal in the interaction with peers at child care settings. The study used data of 1,802 families who have been participating in the Korean Child Panel Study since 2008. The results revealed that there was a significant relation from both positive home environment and better language skills to more positive play interaction and reduced play disruption and play disconnection. Home environment significantly predicted better expressive language development of young children and, in turn, higher scores on expressive vocabulary tests predicted greater peer competence and less negative play behaviors rated by child care providers. Statistical tests proved that the mediational effects of language skills between home environment and toddler's peer relationships were statistically significant. The study results emphasized the importance of language development in children's expanding social settings and the supporting role of rich and stimulus home environments in children's development.

Purpose: The purpose of this study was to develop and validate a Nursing Competency Scale in Simulation (NCSS) for nursing students. Methods: A preliminary version of the NCSS of 14 items was derived from the literature. A panel of seven experts reviewed the preliminary version for content validation and developed 15 items scale. A convenient sample of 195 nursing students completed the survey and two evaluators measured the performances of nine teams in a simulation scenario with NCSS. The data were analyzed using exploratory factor analysis, descriptive statistics, independent t-test and Cronbach's alpha. Intraclass correlation coefficient (ICC) was used in order to estimate the degree of inter-rater reliability. Results: An exploratory factor analysis demonstrated that two factor structures of the NCSS explained 51.1% of the total variance. Two factors were named psychosocial skills and cognitive and psychomotor skills. The mean scores of NCSS between third and 4th grade were significantly different providing support for its known-group validity. Cronbach's alpha was .90 and ranged from .79 to .88. The overall ICC for inter-rater agreement was 0.89 (95% CI 0.03 to 0.98). Conclusion: This scale shows preliminary evidence for validity and reliability. It could be a useful instrument for measuring learning outcome in simulation for nursing students' clinical competency.
This study conducted a longitudinal analysis to identify the impact of social capital on depression trajectories in later life. For data analysis, the Korean welfare panel data(2006-2012) was utilized and 4001 older adults aged 65 and older were included in the final sample. The results showed that social trust was significantly associated with depression scores at baseline but did not predicted the rate of change in depression over time. A higher level of reciprocity significantly predicted the faster decline in depression over time. For social participation through donation or volunteer, the percentage of participation was very low and it was not significantly related to depression trajectories. Finally as the satisfaction from social relationship becomes more positive, the rate of change in depression tended to decline faster over time. The results of this study indicates that in order to prevent or delay depression in later life, we should help older adults accumulate positive social capital such as social trust and reciprocity through active social interaction.
Purpose: To identify user requirements for electronic nursing record (ENR) systems so as to ensure system usability. Methods: A mixed methods approach were applied in three steps : (i) task and workflow analysis with literature review of nursing documentation, (ii) literature reviews of system usability, and (iii) Use Case idenfication and consensus-based validation. We analyzed the nursing activity logs collected from a time-motion investigation of six hospitals. The Use Cases were validated by eight clinical experts from different hospitals and two experts from academia in a sequential Delphi survey. Consensus was achieved for the significance score and agreement among the panel. Results: Eight task groups and patterns of task flow were observed, which were translated into nine Use Cases. The specification of Use Cases was derived from principles, guidelines, and recommendations on nursing documentation and electronic health record systems, which was organized into three requirements of each Use Case: functionality, information, and design characteristics. Each Use Case achieved an agreement of 50~70%, and significance scores of 4 or 5 on a 5-point Likert scale. Conclusion: The nine Use Case identified were considered to be important and adequate in terms of both clinical and informatics contexts.
This study explored the ESL college learners' perceptions on integrating reading and writing in the context of the reading-to-write composition classroom. Using the panel survey (N=60) that repeatedly measured the same set of individuals at three different times during a semester, this study examined whether students' perceptions on reading-writing integrations were reshaped over the course of classroom practices. The survey instrument was developed to assess the perception scores from less integrative continua to more integrative continua on a 5-point Likert scale. A two-factor ANOVA with repeated measures was performed to evaluate mean differences across the perception groups and over the three treatment times. The results do not demonstrate a significant treatment effect, suggesting that L2 learners' integrative perceptions were stable over the course of the semester. The dynamics in the perception changes differed widely across the perception groups. This result provides insights into understanding students' reading-writing practices and thus into instructional practices applicable to the classrooms. The present study argues for 12 learners' perceptions on integrating reading and writing as a key construct to understand their literacy practices involved in the composing process.

To meet standards for high quality of care and satisfied customers, an evaluation tool about nursing care is necessary. And, We need to evaluate our practice continuously for the improvement in quality and outcomes. This study was intended to develop an evaluation tool about nursing care in NSICU, and was progressed of 3 steps; development, content validity verification and reliability verification. Data were obtained and analysed from Feb. To April, 2000. Development process of the study was as follows A preliminary list was made item by item on the basis of clinical Experience, literature review and patients' record review. Then the standards, criteria and indicators of preliminary evaluation tool were set by 5 clinical nursing panel, and their content validity was reviewed by 27 ICU nurses. Finally, an evaluation tool was developed and verified the reliability at c-university hospital located in Kwang-Ju. The results of this was as follows 1) The evaluation tool of this study developed 8 standards, 39 criterias and 106 indicators. The standards were divided into two dimensions. One was process dimension which contained 4 standards(26 criteria), The other was outcome dimension which contained 4 standards(13 criteria). 2) the Average content validity of the tool was 3.39 at standards, 3.55 at criteria and 3.51 at indicators. 3) Interrater reliability of the tool is r=.7993(p<.001) & internal consistency reliability ${\alpha}$ is .6031 4) Scores of NSICU Patients who participated in this study were 57 at total mean score, 58 at process mean score and 56 at outcome mean score The evaluation tool developed in this study seems to be useful in evaluation nursing practice appropriately for the improvement of nursing care in NSICU. I hope that this evaluation tool can be used effectively in NSICU as an intervention for the improvement of quality control.
The aim of this research was to develop a practical use of the citron (Citrus junos Sieb.) leaf, which is a by-product of the citron cultivation, by introducing it into the Jeolpyun, one of the most popular rice cakes in Korea. To achieve the goals of this research, the citron leaf Jeolpyun (CLJ) was first precipitated. The sensory properties and physical examination of products containing 0 (control), 1.0, 1.5, 2.0, and 2.5% of the dried citron leaf powders were then assessed by employing sensory evaluations and instrumental measurements for texture and color. A total of one-hundred and fifty women panelists in age categories of 20s, 30s, 40s, and over 50 were randomly selected from residents in the Seoul area. In general, the highest sensory evaluation scores were obtained for CJLs containing 2% of the citron leaf powders by all panel groups although there was some variation. As levels of the citron leaf powder in the CLJ increased, the texture parameters such as hardness, cohesiveness, and gumminess of the CLJ as measured by the Texture Analyzer significantly increased while adhesiveness decreased and springiness remained constant. Accordingly, the optimal amount of citron leaf powder was determined to be 2% or less for CLJ in order to maintain the original texture of the Jeolpyun. As the levels of the citron leaf powder increased in the CLJ, the Hunter colorimetric L-and a-value significantly decreased while the b-value significantly increased. In other words, the CLJs became darker, as well as deeper in green and yellow tones as the levels of the citron leaf powder increased. The above results indicate that the citron leaf could be successfully used for preparation of Jeolpyun at a concentration around 2%(w/w) based on the consumer preference test and instrument analysis of the products. This research is expected to contribute to the industrial use of citron leaf powder in Jeolpyun and other food products.
An objective method for measuring rancidity in soybean oil was developed based on the volatile contents obtained by headspace gas chromatographic analysis. Apparatus for headspace volatile cold trapping-thermal desorption was described, designed to collect and analyze volatiles of soybean oil. Samples of commercially processed soybean oil were stored under controlled condition and then evaluated for flavor by a eight member trained panel and for volatile contents by headspace gas chromatographic analysis. Twenty-three GC peaks were identified on the basis of relative retention time of reference compounds and gas chromatography-mass spectrometry. The volatile compounds identified were autoxidation products of principal unsaturated fatty acids of soybean oil. The simple linear regressions of flavor score with the pentanal or hexanal contents in aged soybean oil gave correlation coefficient of 0.990 and 0.994. respectively. Pentanal and hexanal contents could be used as a potentially useful index for predicting flavor scores of soybean oil.
