Aims: The role of mothers as main caregivers in toddlers with diarrhea and their familiarity with the factors associated with diarrhea is very important in managing the disease and preventing mortality. This study aimed to investigate the mothers’ performance regarding feeding a toddler with diarrhea and related factors.
Instruments & Methods: This cross-sectional descriptive study was performed on 210 mothers who had toddlers with diarrhea that were selected through convenience sampling in Tehran, Iran, in 2021. The parental socio-demographic and toddler clinical characteristics questionnaire and Mother Performance questionnaire were used to collecting data. Data analysis was done using SPSS 20 software.
Findings: The mean age of the mothers and toddlers were 32.69±6.67 years and 23.97±7.24 months, respectively, and about 51.4% of toddlers were boys. The total mean scores of mothers’ performance was 121.92±8.37. There were significant differences in the mean scores of maternal performance based on the father's education level (p=0.03) and marital status (p=0.04). Furthermore, the frequent diarrhea and referral setting (p<0.0001) were significantly different in the hygiene principles and common beliefs dimension. Mothers with wanted pregnancy have better performance in the breastfeeding dimension (p=0.04).
Conclusion: The mothers’ performance regarding diarrhea and its dietary management is low, and less than half of them have a good level of knowledge. So it is necessary to improve and implement relevant policies to control and manage diarrhea.

Educators in reading are cognizant of the importance of proper assessment practices in order to screen for the risk of reading disabilities, guide proper instruction, and evaluate growth.  While teacher preparation programs are striving to equip future teachers with the best reading assessment practices, little is known about the actual knowledge and attitudes that these students have toward assessing English language learners (ELLs). In order to determine the attitudes, perceptions, and knowledge of pre-service teachers (PTs), a survey constructed by the researchers was administered to 105 PTs. The PTs were enrolled in an  ELLs reading assessment course at a public university in Texas. Based on the descriptive statistical analyses, there was a general lack of confidence in ability and/or preparedness to assess the reading abilities of ELLs. On a more positive note, the majority of respondents indicated a positive attitude towards ELLs overall. In addition, an exploratory factor analysis using cross-tabulations was conducted to determine what factors contributed to PTs feeling prepared to assess ELLs reading. This study has implications for teacher educators to recognize the importance of teachers’ having knowledge of ELLs reading assessment practices as this knowledge could enhance teachers’ self-efficacy and confidence in reading assessment of ELLs. It is suggested that teacher educaton programs include a course dedicated to reading assessment to enhance teachers’ content knowledge of basic language constructs and also their pedagogical knowledge of ELLs literacy acquisition and assessment

Objective: To investigate the friction of rabbit’s knee joint with designed pendulum friction tester to diagnose and evaluate different pathological and therapeutic conditions following haemarthrosis, osteoarthritis, and other joint disorders. Materials and Methods: Friction coefficient of 10 adult male Albino rabbit’s joint (5 right and 5 left knees) weighted 1.59 ± 0.27 Kg, after designing and compiling the instrument and its processing software in the Physiotherapy department of Tarbiat Modares University were measured. Maximaum pendulum rotation, number of oscillations to reach equilibrium, coefficient of friction with Stanton’s equation, exponential and linear curve fitting, average logarithmic and linear decrement methods were measured. Results: Maximum rotation after pendulum releasing in the left joints were higher than the right ones, P<0.001. Number of oscillations to reach equilibrium in the left knees were also greater than the right knees, P=0.005. All different friction estimation methods had the same results and showed greater friction in the right in comparison to the left side. Conclusion: The pattern of the joints amplitude decay did not have a linear behaviour and the rabbit’s knee joint coefficient of friction with nonlinear estimations was less than linear ones. The findings revealed that selecting a separate control group in such investigation is essential and the contralateral limb could not be considered as control group. Pendulum friction tester has the capability of evaluating changes in coefficient of friction after application of different therapeutic methods. These changes have important role in diagnosis, evaluation of joint diseases and developing techniques for treating those pathologies.
