Purpose: The objective of this study was to investigate mothers' perception of antibiotic use for their children. Methods: A cross-sectional survey was conducted of a convenient sample of 210 mothers who visited the two pediatric hospitals in D city. Descriptive statistics, t-test, analysis of variance, Kruskal-Wallis test, Mann-Whitney U test, and Pearson correlation coefficients with SPSS WIN 24.0 were used to analyze the data. Results: The perception of mothers on antibiotic use for their children was relatively low (3.28/5) and showed a statistically significant difference based on the mothers' educational background (${\chi}^2=15.30$, p<.001). About 57-77% of participants discontinued or reduced the dosage of the antibiotics if their children's symptoms were relieved, and about 60% of them perceived that antibiotics treat viral infections. Mothers' adherence to specific doses of antibiotics in their children was positively correlated with their knowledge and beliefs (r=.17, p=.014) and their attitude regarding the use of antibiotics (r=.17, p=.014). Only 1.4% of the participants had educational experience regarding the correct use of antibiotics.

There have been many streaming servers that provide a large number of contents for a user's preference. General purpose streaming sewer makes use of a RTSP protocol for streaming controls such as message passing with client players. To date, there has been minimal research regarding streaming server's performance test tools. For measuring streaming server's performance, performance evaluation technique is needed and also achieved by RTSP based controls, a server's performance result and its miscellaneous test tools such the PseudoPlayer for pumping data to a specified port and the PseudoMonitor for gathering information. In this paper, We implement a test toolkit for evaluating a streaming server's performance and show the case of its application

This study explores the effects of various factors on the use of nutrition information on food away from home (FAFH). Consumer groups were classified into groups according to their perception of being overweight and obese (correctly perceiving, underestimating and overestimating weight). For this, frequency analysis, a chi-square test, and an ANOVA were conducted to determine any differences between factors, and a logit analysis (SPSS 18.0) was conducted to identify those factors influencing the use of information. Information recognition, intentions to use information and the use on FAFH showed significant differences across the groups. In addition, health inspection, the perception of the intrinsic quality of restaurants, labeling, FAFH expenditure, and some individual characteristics showed significant differences between groups. The information recognition of FAFH had a significant positive effect on information use in all groups. In all groups, labeling had a significant positive effect on information use, and family health concerns had a significant positive effect on information use in the group correctly perceiving weight. The price of domestic food items, household head and household income had significant positive effects on information use in the group overestimating weight.
