    Supporting all children, particularly children with special needs, in the field of mathematics is important for their development. Therefore, it is necessary to develop and implement the necessary early intervention programs in relation to mathematics education. Studies indicate that early mathematics education intervention programs provide an increase in children’s mathematical knowledge levels improving their mathematics performance. It is also reported that such programs are effective in increasing the mathematical achievement of children at risk and that their effects may last for a longer time. Therefore, it is considered important to support the mathematics skills of the children in the risk group with early mathematics intervention programs, to identify the children whose mathematical skills are deficient or who have not acquired these skills sufficiently in the early period. In this study the is aim to reveal the effectiveness of an intervention program developed in relation to the early mathematics skills to improve such skills of children in the pre-school period between 60-72 months of age, who are in the risk group in terms of mathematics skills. In this study, the multiple probe model inter-subjects, which is one of the single-subject research models, was used. The participants of the study were three kindergarten students from three different schools in Kırşehir, Türkiye. The study was carried out in the special education center located in the said city. The data collection tool is an early mathematics intervention program developed for teaching early mathematics skills. When we look at the findings obtained from the study in general, it appears that the early mathematics intervention program was effective in improving the early mathematics skills of all three students. For this reason, priority should be given to supporting the development of early mathematics skills in all children attending pre-school education institutions. © 2023, Ozgen Korkmaz.

    This study aims to determine the influence of various firm level characteristics such as, profitability, size, growth opportunities, asset tangibility, non-debt tax shield, volatility and liquidity on capital structure. Employing the cross-sectional data methodology, the researcher examines the capital structure determinants of 202 companies from FTSE 250 for the time period of 2002 – 2009. Seven variables multiple regression models are used to estimate the influence of firm level attributes on capital structure and capital structure is measured simultaneously by the ratios of total debt, long-term debt and short-term debt at both book value and market value of equity. The results obtained from four different regression models show that profitability and liquidity are negatively and significantly related to leverage. Also asset tangibility has a positive relationship with leverage, which is significant. Moreover the researcher finds that total debt ratio at market value of equity is the most important dependent variable as a proxy of capital structure, followed by long-term debt ratio at market value of equity.Capital structure, leverage, capital structure determinants, firm level characteristics, profitability, size, growth opportunities, asset tangibility, non-debt tax shield, volatility, liquidity

    This study aims to examine the opinions of parents with children with special needs regarding the distance education process by using SWOT analysis. The research was carried out in the phenomenology study model, which is one of the qualitative research methods. The study group of the study consists of 10 parents who have children with special needs and who voluntarily agree to participate in the study. The data of the research were obtained by using the semi-structured "Special Education Evaluation Form in Distance Education" prepared by the researchers. SWOT analysis was performed on the written documents collected within the scope of the research by using the content analysis method. As a result of the research; It has been observed that parents of children with special needs have many advantages for their children and themselves, but they have difficulties in certain areas due to some limitations of distance education. The results of the research were discussed concerning the literature and recommendations were made

    Ultrasound Findings in a Case of Myeloid Sarcoma of the Breast

    Get PDF
    Myeloid sarcoma is a rare, solid extramedullary tumor originating from immature granulocytic cells or monocytes. Breast involvement without an aleukemic or myeloproliferative disorder is very infrequent. A 21-year-old female patient was admitted with bilateral palpable breast masses for four months. The patient had given birth approximately one year ago. The ultrasonographic examination revealed multiple, oval shaped—some of them with microlubulated margins—hypoechoic, solid masses of which, the largest mass measured 4.5 . 2.5 cm, evaluated as BI-RADS 4. The histopthological examination suggested hematolymphoid neoplasm. In the differential diagnosis of solid breast lesions, myeloid sarcoma should be kept in mind even without hematological findings. Early diagnosis of this tumor is important for the effectiveness of the medical treatment

    Objective:The aim of this study was to investigate and compare the auditory findings in vestibular migraine (VM) and migraine patients without a history of vertigo.Methods:This study was conducted on 44 patients diagnosed with definite VM and 31 patients diagnosed with migraine who were followed and treated between January 2011 and February 2015. Also, 52 healthy subjects were included in this study as a control group. All participants underwent a detailed otorhinolaryngological examination followed by audiological evaluation, including pure tone audiometry, speech reception threshold, speech recognition score, and acoustic immitancemetry.Results:In the VM group, there were 16 patients (36.4%) with tinnitus, while in the other groups we did not observe any patients with tinnitus. The rate of tinnitus in the VM group was significantly higher in comparison to other groups (p<0.05). None of the groups had any patients with permanent or fluctuating sensorineural hearing loss.Conclusion:We conclude that patients with VM should be closely and longitudinally followed up for the early detection of other otological symptoms and possible occurrence of sensorineural hearing loss in the long term

    The effect of directional social cues on saccadic eye movements in Parkinson’s disease

    There is growing interest in how social processes and behaviour might be affected in Parkinson’s disease. A task which has been widely used to assess how people orient attention in response to social cues is the spatial cueing task. Socially relevant directional cues, such as a picture of someone gazing or pointing to the left or the right have been shown to cause orienting of visual attention in the cued direction. The basal ganglia may play a role in responding to such directional cues, but no studies to date have examined whether similar social cueing effects are seen in people with Parkinson’s disease. In this study, patients and healthy controls completed a prosaccade (Experiment 1) and an antisaccade (Experiment 2) task in which the target was preceded by arrow, eye gaze or pointing finger cues. Patients showed increased errors and response times for antisaccades but not prosaccades. Healthy participants made most anticipatory errors on pointing finger cue trials, but Parkinson's patients were equally affected by arrow, eye gaze and pointing cues. It is concluded that Parkinson's patients have a reduced ability to suppress responding to directional cues, but this effect is not specific to social cues

    Representing Where along with What Information in a Model of a Cortical Patch

    Behaving in the real world requires flexibly combining and maintaining information about both continuous and discrete variables. In the visual domain, several lines of evidence show that neurons in some cortical networks can simultaneously represent information about the position and identity of objects, and maintain this combined representation when the object is no longer present. The underlying network mechanism for this combined representation is, however, unknown. In this paper, we approach this issue through a theoretical analysis of recurrent networks. We present a model of a cortical network that can retrieve information about the identity of objects from incomplete transient cues, while simultaneously representing their spatial position. Our results show that two factors are important in making this possible: A) a metric organisation of the recurrent connections, and B) a spatially localised change in the linear gain of neurons. Metric connectivity enables a localised retrieval of information about object identity, while gain modulation ensures localisation in the correct position. Importantly, we find that the amount of information that the network can retrieve and retain about identity is strongly affected by the amount of information it maintains about position. This balance can be controlled by global signals that change the neuronal gain. These results show that anatomical and physiological properties, which have long been known to characterise cortical networks, naturally endow them with the ability to maintain a conjunctive representation of the identity and location of objects
