The present study was conducted with the aim of investigating the effectiveness of executive functions on the working memory of students with math learning disorders.

The method of this research was semi-experimental with a pre-test-post-test design with a control group. The statistical population included all elementary school students with math disorders who referred to the Center for Learning Difficulties in Noor city in the academic year of 2019-2020. 30 of these students were selected by available sampling and randomly assigned to two experimental and control groups, 15 each. In the implementation of this research, the capacity measurement testWorking memory of Danimin Carpenter (1980) was used and the training program of executive functions (Sahibani et al., 2019) was implemented for 10 sessions of 60 minutes and twice a week for the participants of the experimental group. If the control group did not receive any intervention. Data were analyzed using analysis of covariance.

The results showed that the training of the executive functions of the brain significantly increased the working memory of the students in the experimental group compared to the control group (p<0.001).

From the present study, it can be concluded that the training of the executive functions of the brain is effective on the working memory of students with math learning disorders and has improved it.

Long-ranged guided wave inspection systems are often used in a low frequency–thickness range below the cut-off frequency of the higher wave modes to simplify data interpretation. In this paper, the potentials of ultrasonic high order guided wave modes are studied in the inspection of plate structures. The wave propagation characteristics of high order wave modes and the corresponding sensitivity and detectability are investigated. Using the commercially available software ABAQUS, finite element simulations are carried out to model the ultrasonic wedge transducer and the inspection system for simulation of A1 and S1 wave mode distribution. Using a variable angle transducer, experimental pulse–echo technique is employed to evaluate the measurement relative errors obtained from two high order wave modes, A1 and S1, for a 2 mm steel plate at 4 MHz.mm of frequency–thickness. The experimental measurements show that for various transducer positions, the relative errors obtained by the S1 mode are less than 10% for short-range measurements.

Numerous methods have been tested in the field of rehabilitation of dyslexic students. The purpose of this study was to compare the effectiveness of computer-based cognitive rehabilitation and neuro-psychological exercises on reading speed, accuracy and comprehension of students with dyslexia.

The method was quasi-experimental and its design was multi-group with pretest and posttest phases. The statistical population was included all elementary school students with developmental dyslexia of Amol and Mahmood-abad cities during the academic year of 1397-98, who were referred to learning disability centers. 45 samples were selected by convenience sampling and assessed by Raven IQ test and a Persian version of reading and dyslexia test (NAMA). Samples were randomly assigned to experimental and control groups after confirming diagnose from LD experts. Interventions were conducted in methods of computer-based cognitive rehabilitation and practical cognitive rehabilitation for experimental groups in 14 sessions, but the control group did not receive any intervention. Reading speed, accuracy and comprehension were measured via NAMA test in two pre-test and post-test stages. Data were analyzed by multivariate analysis of covariance with Bonferroni post-hoc test.

The results showed that computerized cognitive rehabilitation was more effective on the amount of reading speed and accuracy, but in comprehension, the practical method was more effective.

Computerized cognitive rehabilitation and practical cognitive rehabilitation are effective on dyslexia and these interventions can be complementary to each other in order to improve reading performance.

The purpose of this study was to compare the effectiveness of computer-based cognitive rehabilitation and practical neuropsychological interventions on working memory and sustained attention in students with dyslexia. The method of this study was experimental and its design was multi-group pretest and posttest with control group. Statistical population of this study included elementary students with dyslexia in Amol and Mahmoudabad cities during the academic year of 1397-98, who were referred to learning disability centers. 45 students were selected by convenience sampling method and assisted by diagnostic tests of Raven and reading and dyslexic test (NAMA). They were randomly assigned to experimental and control groups. The experimental groups were received 14 interventions sessions. The computer version of the n-back test and computer version of the continuous performance task were used for gathering data in two pre and posttest stages. Data were analyzed by multivariate analysis of covariance. The results showed that computer-based rehabilitation was more effective (P<0.05) on the amount of correct responses in sustained attention, and correct response and reaction time in working memory in comparing to practical neuropsychological exercises. These results reveal that computerized cognitive rehabilitation with providing the visual and audio attractions and the creation of opportunities appropriate to the level of child's development can provide a more appropriate field for improving the defects of the high-quality functions of the minds of people with dyslexia.

Organizations need to employ committed individuals for their survival and development as well as to achieve their short- and long-term goals. In account of this, successful organizations are those with committed managers and staff. Therefore, it is important to investigate the factors influencing organizational commitment. The aim of this study was to investigate the mediating role of psychological capital in the relationship between spiritual intelligence and organizational commitment among employees of Ardabil University of medical sciences using a correlational method (structural equation modeling). Regarding the desirable size of the sample (n=125) for structural equation modeling, 183 employees were selected using convenience sampling method. The results showed that the direct effect of spiritual intelligence on organizational commitment and the direct effect of psychological capital on organizational commitment are statistically significant. Also, the spiritual intelligence may effect organizational commitment through psychological capital as mediator (p≤ 0.01, β=0.41).

The aim of present research was to predict the tendency towards risk-taking behaviors in adolescents by family cohesion and self-worth. Research method was cross-correlational. The population was equal to 1320 individuals, included all high school students of the public high schools in Bojnoord city in the academic year of 2014-2013. A sample of 300 students were selected by multi-stage cluster sampling, Chosen from 7 schools With 2 class of each school. The instruments were Iranian youth risk-taking scale, Fisher's family cohesion scale and self-worth contingency questionnaire. Data were analyzed by using descriptive statistics, correlation and stepwise multiple regression model. Results showed that family cohesion and self-worth negatively correlated with all sub-scales of tendency towards risky behavior. In the final step of regression model, family cohesion and self-worth significantly predicted tendency towards risky behavior. Family cohesion as an effective internal source, and self-worth as an effective external source, act as protective shields to adolescents tendencies toward risk-taking behaviors.

Rodents are considered as reservoirs of various zoonotic diseases including helminthic infections. The current study aimed to evaluate the prevalence of helminth infections in rodents, in Boyer-Ahmad district, Southwestern Iran.
Overall, 52 rodents were captured from various areas of the district by Sherman live traps. The animals were then euthanized and dissected. During necropsy, each organ was examined macroscopically for presence of any cyst or visible parasite. The gastrointestinal tract was removed and their contents were evaluated for larva or adult worms. Trichinella larvae in the rodents’ muscles were investigated by both digestion and pathological methods.
Twenty-eight (53.8%) of the trapped rodents were male. The rodents were including 25 (48.1%) Meriones persicus, 1(1.9%) Calomyscus bailwardi, 1 (1.9%) Arvicola terresterris, 7 (13.5%) Rattus rattus, 8 (15.4%) R. norvegicus, and 10 (19.2%) Apodemus sylvaticus. Of them, 38 (73.0%) were infected with at least one helminth. Collected rodents were infected with Hymenolepis diminuta (50%), Hymenolepis nana fraterna (28.8%), Skrjabinotaenia sp. (15.4%), Anoplocephalidae sp. (15.4%), Cysticercus fasciolaris (5.8%), Trichuris muris (36.5%), Aspiculuris tetraptera (15.4%), Syphacia sp. (5.7%), Rictularia sp. (15.4%), Trichostrongylus sp. (3.8%), and Gongylonema sp. (3.8%). M. persicus was the most (84%) infected rodent, yet the differences between rodent genus and helminth infectivity were not statistically significant (P>0.05).
The rodents in Boyer-Ahmad district are infected with different helminths infections that some of them are recognized as threat to human health.

The traumatic use of mobile phones is counting as common behavioral problems in adolescents, and many of internal and external variables, including loneliness and family cohesion may be have impact on it. The aim of this study is to investigate the role of family cohesion and loneliness to anticipate the traumatic use of mobile phones among high school students. For this purpose, 170 students that are studying in government schools at Mahmudabad city in the academic year of 94-1393 with the multi-phase cluster sampling have selected, and they responded to the Feeling Loneliness short-form test of California University, and traumatic using of mobile-phone scale and Fisher’s family cohesion scale. At the final step of the analysis, the result shows that, family cohesion negatively and the feelings of loneliness positively anticipate traumatic mobile phone. This finding is supporting the importance of family cohesion and loneliness variables in turning teenagers to traumatic usage of cell phone. It seems that training programs related to family cohesion to be increased and social skills development associated with adolescents take the part of reducing the traumatic use of mobile phones
