INVESTIGATION OF THE EFFECTS OF BADMINTON EXERCISES ON ATTENTION DEVELOPMENT IN AUTISTIC CHILDREN
Background: The most common problems in individuals with autistic spectrum disorders are eye contact, being able to follow objects for a long time and lack of attention. Sports activities are known to prevent the negative symptoms of Autistic Spectrum Disorder. The Badminton sports branch has a positive effect on the individual's object control, ball focus, and attention, reaction, perception and coordination characteristics. For this reason, racket sports are considered to be an important tool in reducing the lack of attention in individuals with Autistic Spectrum Disorder.Aim: The aim of this study, Investigation of the effect of simplified Badminton exercises on attention focus development of individuals with Autistic Spectrum Disorder and is the assessment of the level of retention of an acquisition.Material and Method: The study group was randomly selected 3 out of 6 children who are not mentally retarded and responded to commands among 10 children aged 12-14 years in Isparta Gülşen Önal Autistic Children Education Centre. The mean age of children was 12.6 ± 1.15 years, height was 154,3±5,13 cm and weight was 52±3 kg. Benton Visual Memory Test, Bourdon Visual Attention Test and Stroop Effect Test were used as the measurement tool. Children were performed adaptation exercises for 2 weeks and from simple to difficult badminton exercise drills for 10 weeks. For each individual, 3 studies were performed at different times and 60 minutes per week. Tests were performed at 3 different periods, to be 10 weeks Badminton exercise process before and after and also retention test after 8 weeks interval. The obtained data were evaluated by Wilcoxon test.Results: According to the results of all measurement instruments of the students participating in the research, there is a numerical rise between pre - test and post - test values. When the results of the retention test with the last test are evaluated, there was no decrease in the two participants according to the Benton visual memory test results, but the other participant had also decline, although not at the beginning level. Burdon attention test and Stroop effect test showed that there was no return to baseline in all participants despite a numerical decrease.Conclusion: We can say that Badminton exercise program has a positive effect on attention level. Individuals with autistic spectrum disorder can be said to have a positive influence on the development of eye contact, long-time focus of objects and attention level development. Badminton exercises can be offered as a model to improve attentiveness to children with Autistic Spectrum Disorder if the duration of participatory study is increased. Article visualizations
Lossless Text Compression Technique Using Syllable Based Morphology
In this paper, we present a new lossless text compression technique which utilizes syllable-based morphology of
multi-syllabic languages. The proposed algorithm is designed to partition words into its syllables and then to produce their shorter bit representations for compression. The method has six main components namely source file, filtering unit, syllable unit, compression unit, dictionary file and target file. The number of bits in coding syllables depends on the number of entries in the dictionary file. The proposed algorithm is implemented and tested using 20 different texts of different lengths collected from different fields. The results indicated a compression of up to 43%
Products, coproducts and singular value decomposition
Products and coproducts may be recognized as morphisms in a monoidal tensor
category of vector spaces. To gain invariant data of these morphisms, we can
use singular value decomposition which attaches singular values, ie generalized
eigenvalues, to these maps. We show, for the case of Grassmann and Clifford
products, that twist maps significantly alter these data reducing degeneracies.
Since non group like coproducts give rise to non classical behavior of the
algebra of functions, ie make them noncommutative, we hope to be able to learn
more about such geometries. Remarkably the coproduct for positive singular
values of eigenvectors in yields directly corresponding eigenvectors in

Does Fiscal Decentralization Promote Fiscal Discipline?
We investigate the efficiency and equity implications of a redistributive rule that takes into account both local tax collection efforts and deviation of local incomes from respective targets under alternative fiscal mechanisms. We show that, if the general budget constraint is binding, the proposed transfer rule leads to higher fiscal discipline under fiscal decentralization (FD) than under centralized redistribution. Although the centralized decision yields better income distribution than FD, FD also improves income distribution unambiguously when equalization across regions is targeted explicitly. When localities act strategically, the private sectors utility weight enhances the disciplinary effect of decentralization. © 2016 Taylor & Francis Group, LLC
Oral squamous cell carcinoma detection by salivary biomarkers in a Serbian population
Early detection of oral squamous cell cancer (OSCC) is the key to improve the low 5-year survival rate. Using proteomic and genomic technologies we have previously discovered and validated salivary OSCC markers in American patients. The question arises whether these biomarkers are discriminatory in cohorts of different ethnic background. Six transcriptome (DUSP1, IL8, IL1B, OAZ1, SAT1, and S100P) and three proteome (IL1B, IL8, and M2BP) biomarkers were tested on 18 early and 17 late stage OSCC patients and 51 healthy controls with quantitative PCR and ELISA. Four transcriptome (IL8, IL1B, SAT1, and S100P) and all proteome biomarkers were significantly elevated (p lt 0.05) in OSCC patients. The combination of markers yielded an AUC of 0.86, 0.85 and 0.88 for OSCC total, T1-T2, and T3-T4, respectively. The sensitivity/specificity for OSCC total was 0.89/0.78, for T1-T2 0.67/0.96, and for T3-T4 0.82/0.84. In conclusion, seven of the nine salivary biomarkers (three proteins and four mRNAs) were validated and performed strongest in late stage cancer. Patient-based salivary diagnostics is a highly promising approach for OSCC detection. This study shows that previously discovered and validated salivary OSCC biomarkers are discriminatory and reproducible in a different ethnic cohort. These findings support the feasibility to implement multi-center, multi-ethnicity clinical trials towards the pivotal validation of salivary biomarkers for OSCC detection
Studying Brugada syndrome with an SCN1B variants in human-induced pluripotent stem cell-derived cardiomyocytes
BACKGROUND: Among rare channelopathies BrS patients are at high risk of sudden cardiac death (SCD). SCN5A mutations are found in a quarter of patients. Other rare gene mutations including SCN1B have been implicated to BrS. Studying the human cellular phenotype of BrS associated with rare gene mutation remains lacking. OBJECTIVES: We sought to study the cellular phenotype of BrS with the SCN1B gene variants using human-induced pluripotent stem cell (hiPSCs)–derived cardiomyocytes (hiPSC-CMs). METHODS AND RESULTS: A BrS patient suffering from recurrent syncope harboring a two variants (c.629T > C and c.637C > A) in SCN1B, which encodes the function-modifying sodium channel beta1 subunit, and three independent healthy subjects were recruited and their skin biopsies were used to generate hiPSCs, which were differentiated into cardiomyocytes (hiPSC-CMs) for studying the cellular electrophysiology. A significantly reduced peak and late sodium channel current (I(Na)) and a shift of activation curve to more positive potential as well as a shift of inactivation curve to more negative potential were detected in hiPSC-CMs of the BrS patient, indicating that the SCN1B variants impact the function of sodium channels in cardiomyocytes. The reduced I(Na) led to a reduction of amplitude (APA) and upstroke velocity (V(max)) of action potentials. Ajmaline, a sodium channel blocker, showed a stronger effect on APA and Vmax in BrS cells as compared to cells from healthy donors. Furthermore, carbachol was able to increase arrhythmia events and the beating frequency in BrS. CONCLUSION: Our hiPSC-CMs from a BrS-patient with two variants in SCN1B recapitulated some key phenotypic features of BrS and can provide a platform for studies on BrS with SCN1B variants
Impact of deicing salts on pervious concrete pavement
Two pervious concrete projects (named as SR28 and SR431), with the same mixture design but different winter maintenance activities, were included in this research. Both projects are located in the Lake Tahoe area, Nevada, United States. Testing results indicated that the mechanical properties were significantly higher in SR28 cored samples than the ones in SR431. It was found that the SR28 pieces have fewer air voids, while the SR431 samples have higher water absorption and hydraulic conductivity, and the SR28 samples show fare better performance against repeated freezing and thawing cycles than the SR431 ones. scanning electron microscope pictures of crack surfaces in cores taken from SR28 indicate that the cement binder phase has been largely retained. However, in the coring sample of SR431, needle-shaped residues can be seen within the cement binder phase and an abundance of precipitated micro-sized crystalized particles can be observed. On a micrometer scale, the μCT examination reveals that the porosity of SR28 samples is significantly less than that of SR431. The analyzing results give a clue to demonstrate the durability of pervious concrete pavement can be attributed to the construction quality control, maintenance activity, or the weather and locations of the field sites
