Abstract: Background: Phonemic awareness is one of the most important predictors of reading skills that has been taught by different procedures. One of the procedures is implementation of direct instruction in instruction of phonemic awareness. Current study is one of the unique studies in Iran that investigate impact of direct instruction in phonemic awareness on reading achievement of students with reading disorder.Case: Three male second grade elementary students with reading disorder in a regular school in district six of the office of education in Tehran were selected. Multiple-baseline across subjects was selected as a research design. The following tests were used as diagnostic criteria: reading and dyslexia test and Wechsler intelligence scale for children-revised. Moreover, a reading inventory consisting of 100 words was developed by researchers to assess the reading ability of the subjects. Data were collected in three phases: baseline, intervention, and follow-up. During the intervention phase, the intervention strategies were used while during baseline and follow-up, data were collected without any intervention. Comparing three phases of the study, we may conclude that intervention package consisting of direct instruction of phonological awareness was an effective strategy in reading achievement of all three students. In addition, follow-up data indicated that the effects of the intervention procedures were stable across time.Conclusion: Direct instruction of phonological awareness was effective in reading achievement of students with reading disorder in elementary school and increasing their abilities in reading.

Iranian Journal of Psychiatry , 2011,
Abstract: Beneficial effects of stimulants on core symptoms of Attention Deficit Hyperactivity Disorder (ADHD) have been reported in several studies. Behavioral interventions have also been proposed as empirically supported interventions for ADHD. Although cognitive-behavioral therapies (CBT) have been criticized for the lack of evidence-based data, some studies have indicated the positive effects of CBT techniques on children with attention deficit hyperactivity disorder (ADHD). This article reports the effects of self-monitoring technique, as a CBT technique, on inattentive behaviors of children with ADHD.

Audiology , 2012,
Abstract: Background and Aim: Having healthy non-handicapped children plays a major role in mental health of the family and decreases family and society's costs. While consanguineous marriage could lead to expression of recessive genes and a variety of handicaps including deafness, the aim of present study was to scrutinize the prevalence of consanguineous marriage among parents of deaf and normal children as well as its relationship with deafness.Methods: In this study, 467 couples parenting normal children were selected by cluster sampling from elementary, guidance and high schools of Ardabil city and 423 couples parenting disabled children were selected non-randomly among which 130 had deaf children. Descriptive statistics was used to determine the prevalence of consanguineous marriage and chi-square test to compare prevalence of consanguineous marriage among parents of normal and deaf children.Results: Descriptive analyses showed that 80 out of 130 (61.54%) parents who had deaf children have had consanguineous marriage. Furthermore data analysis demonstrated that prevalence of consanguineous marriage was significantly higher among parents of deaf children (p<0.001).Conclusion: Consanguineous marriage plays a major role in expression of recessive genes and could lead to development of various handicaps including deafness. Increasing couples' awareness about consequences of consanguineous marriage and conducting genetic counseling are indispensable.
Numerical Solution of Model of Cancer Invasion with Tissue  [PDF]
Farhad Hatami, Mohammad Bagher Ghaemi
Applied Mathematics (AM) , 2013, DOI: 10.4236/am.2013.47143

Chemotaxis-haptotaxis model of cancer invasion with tissue remodeling is one of the important PDEs systems in medicine, mathematics and biomathematics. In this paper we find the solution of chemotaxis-haptotaxis model of cancer invasion using the new homotopy perturbation method (NHPM). Then by comparing some estimated numerical result with simulation laboratory result, it shows that NHPM is an efficient and exact way for solving cancer PDEs system.

Investigation of Some Effective Factors in the Efficiency ofPheromone Traps of Oak Leaf Roller Moth Tortrix viridana L. (Lep.: Tortricidae) in Kurdistan Province

Journal of Science and Technology of Agriculture and Natural Resources , 2009,
Abstract: One of the most important pest in the Oak forest of Kurdistan province is Oak leaf roller moth, Tortrix viridana L. (Lep.: Tortricidae). Use of pheromone trap is one of the suitable methods for monitoring and controlling of the pest. In this work, three main factors which affect the efficiency of traps including trap type, pheromone dose and installation height trap were studied. Four types of trap including cylindrical, rectangular, delta and wing trap were tested. Capture efficiency of the traps, were installed in the middle, and top heights of the trees were compared. Three doses of pheromone 0.5, 1, and 1.5 mgr per trap were also compared. Results showed that there were significant differences among four types of traps. Cylindrical, rectangular and delta traps caught more number of moths than wing trap (P<0.05). There were no significant differences between two installation heights (P>0.05). However, a significant differences was observed among three doses (P<0.05), and the dose of 0.5 mg caught more moths than the other three doses. Therefore cylindrical traps containing 0.5mg of synthetic sex pheromone installed in the middle of the trees canopy may be recommended in the management program of the pest.

International Journal of Computer Science Issues , 2012,
Abstract: Query Optimization is one of fundamental problems in grid databases. Especially, when the databases are replicated and stored in different nodes of the network. with regard to the point that query in grid databases can be processed in different sites, The problem of choosing suitable sites to execute query is very important. In this article, to choose the sites particle swarm optimization algorithm has been used. To this purpose one function has been used as fitness function in a way that it takes into account the required memory to execute a certain query. Also, the time needed to execute a query and the cost to do so or both of them have been taken into account to perform a query suitably in certain site which is effective in allocating the site to perform a certain query. In this article different repetitions on different particles with regard to cost and time needed to execute a query in different sites have been conducted and the simulation results have been compared with each other.

Zahedan Journal of Research in Medical Sciences , 2012,
Abstract: Background: There is little information about the relationship of alexithymia and cognitive/behavioral coping strategies with psychological vulnerability. The recent studies indicate that alexithymia and coping strategies affect psychological vulnerability. The present study aims to determine the relationship of alexithymia and cognitive/behavioral coping strategies with psychological vulnerability of women with somatization disorder. Materials and Methods: The samples of this study included 120 patients with somatization disorder who were selected as convenience sampling among those who attended the psychology centers of Ardabil. Pain coping questionnaire, alexithymia questionnaire, and symptom questionnaire were used to collect the information. The research data were analyzed using the Pearson’s correlation coefficient and multivariate regression analysis methods. Results: The results indicated that there are significant correlations between alexithymia (r = 0.52), cognitive coping strategies (r = -0.27), behavioral coping strategies (r = -0.33) and psychological vulnerability of women with somatization disorder. The results of step-by-step multivariate regression analysis suggested that alexithymia and cognitive/ behavioral coping strategies clarifies 37 percent of the variance of psychological vulnerability of women with somatization disorder.Conclusion: These findings indicate that cognitive/behavioral coping strategies and alexithymia are associated to psychological vulnerability of women with somatization disorder. In addition, these results have special application in prevention, pathology as well as psychotherapy of this disorder.
Global Existence of Classical Solutions to a Cancer Invasion Model  [PDF]
Khadijeh Baghaei, Mohammad Bagher Ghaemi, Mahmoud Hesaaraki
Applied Mathematics (AM) , 2012, DOI: 10.4236/am.2012.34059
Abstract: This paper deals with a chemotaxis-haptotaxis model of cancer invasion of tissue. The model consists of three reaction- diffusion- taxis partial differential equations describing interactions between cancer cells, matrix degrading enzymes, and the host tissue. The equation for cell density includes two bounded nonlinear density-dependent chemotactic and haptotactic sensitivity functions. In the absence of logistic damping, we prove the global existence of a unique classical solution to this model by some delicate a priori estimate techniques
