Abstract Introduction: Crosswords have been used to complement medical education in a fun way, yet they were not used as a method for the evaluation of students' performance. Objective: The aim of this study was to describe the development of crosswords and verify their validity as a method of performance evaluation in embryology. Materials and Methods: We used crossword based on subjects about stages of embryonic development with different levels of difficulty. To validate the crossword as the evaluation method of teaching, two evaluation methods were applied (the traditional and with crosswords, simultaneously) on students of Federal University of Piaui. The performance of students was analyzed with Pearson's correlation coefficient and data were analyzed to check for normal distribution through the Shapiro-Wilk test with significance level of 0.05. The tests were performed on the BioEstat statistical software version 5.0. Results: As result a total of 28 students were evaluated. It was observed that the resulting score of both the traditional and crossword evaluation methods demonstrating normal distribution (p=0.4127 and p=0.7016, respectively), did not present vices and tendencies. The average scores were 7.1 ± 2.0 and 6.9 ± 1.7 for the traditional and crossword evaluation methods, respectively, showing statistically significant difference (p=0.0001; r=0.67), demonstrating a moderate Pearson's correlation between the methods. Conclusion: In conclusion, crosswords may be used as supplementary material for teaching embryology. Also, crossword functioned as validated and reproducible method of performance evaluation that can be used in as alternative and/or complementary teaching of embryology or other disciplines in the medical ield.

To determine the risk associated with combined therapy of oral hypoglycemic agents and insulin in the development of cognitive decline secondary to hypoglycemia. The study comprised of two arms, in arm 1 (n=30) diabetic patients on OHA and insulin combined therapy were observed for cognitive derangement based on Mini Cog score (Pearson’s correlation r was calculated between the two)and the patients were also ruled out for hypoglycemia episodes. Similarly, in arm 2(n=30), only OHA therapy patients were evaluated on the same parameters using Pearson’s correlation. Mean Mini Cog scores were found to be 1.79  in patients on combinational therapy of OHA and insulin. In the case of patients only on OHA for diabetes control mean Mini Cog, the score was 2.0. Pearson’s coefficient r 1 between OHA plus insulin duration of therapy in years with Mini Cog score was  -0.5831 at a statistically significant p value of 0.0007. While on the other hand, patients only on OHA therapy (in years)were not significantly correlated with Mini Cog scores.(r 2= - 0.0149 ; p value =0.93771).In the arm 1 (OHA + Insulin(n=30)), the average number of hypoglycemia episodes were found to be 2.633 as compared to the OHA only group in which mean hypoglycemia episodes were 0.866. There was a significant difference in the hypoglycemia episodes, as confirmed by the student t-test (4.06368) at a p value = 0.000147. Based on the study findings, combined Treatment with Oral Hypoglycemic agents and insulin in longer run may lead to cognitive derangement secondary to hypoglycemia.*Significance level <0.01, Negative correlations are indicative of lower the values of battery scores higher would be cognitive derangement.

ABSTRACT Aim The E4D Compare software is an innovative tool that provides immediate feedback to students’ projects and competencies. It should provide consistent scores even when different scanners are used which may have inherent subtle differences in calibration. This study aimed to evaluate potential discrepancies in evaluation using the E4D Compare software based on four different NEVO scanners in dental anatomy projects. Additionally, correlation between digital and visual scores was evaluated. Materials and methods Thirty-five projects of maxillary left central incisors were evaluated. Among these, thirty wax-ups were performed by four operators and five consisted of standard dentoform teeth. Five scores were obtained for each project: one from an instructor that visually graded the project and from four different NEVO scanners. A faculty involved in teaching the dental anatomy course blindly scored the 35 projects. One operator scanned all projects to four NEVO scanners (D4D Technologies, Richardson, TX, USA). The images were aligned to the gold standard, and tolerance set at 0.3 mm to generate a score. The score reflected percentage match between the project and the gold standard. One-way ANOVA with repeated measures was used to determine whether there was a significant difference in scores among the four NEVO scanners. Paired-sample t-test was used to detect any difference between visual scores and the average scores of the four NEVO scanners. Pearson's correlation test was used to assess the relationship between visual and average scores of NEVO scanners. Results There was no significant difference in mean scores among four different NEVO scanners [F(3, 102) = 2.27, p = 0.0852 one-way ANOVA with repeated measures]. Moreover, the data provided strong evidence that a significant difference existed between visual and digital scores (p = 0.0217; a pairedsample t-test). Mean visual scores were significantly lower than digital scores (72.4 vs 75.1). Pearson's correlation coefficient of 0.85 indicated a strong correlation between visual and digital scores (p < 0.0001). Conclusion The E4D Compare software provides consistent scores even when different scanners are used and correlates well with visual scores. Clinical significance The use of innovative digital assessment tools in dental education is promising with the E4D Compare software correlating well with visual scores and providing consistent scores even when different scanners are used.

AbstractUnderstanding intra-specific variation in leaf functional traits is one of the key requirements for the evaluation of species adaptive capacity to ongoing climate change, as well as for designing long-term breeding and conservation strategies. Hence, data of 19 functional traits describing plant physiology, antioxidant properties, anatomy and morphology were determined on 1-year-old seedlings of wild cherry (Prunus avium L.) half-sib lines. The variability within and among half-sib lines, as well as the estimation of multi-trait association, were examined using analysis of variance (ANOVA) followed by Tukey's honestly significant difference test and multivariate analyses: principal component analysis (PCA), canonical discriminant analysis (CDA) and stepwise discriminant analysis (SDA). Pearson’s correlation coefficient was used to evaluate linear correlation between the study parameters. The results of the ANOVA showed the presence of statistically significant differences (P < 0.01) among half-sib lines for all study traits. The differences within half-sib lines, observed through the contribution of the examined sources of variation to the total variance (%), had higher impact on total variation in the majority of the examined traits. Pearson’s correlation analysis and PCA showed strong relationships between gas exchange in plants and leaf size and stomatal density, as well as between leaf biomass accumulation, intercellular CO2 concentration and parameters related to antioxidant capacity of plants. Likewise, the results of SDA indicate that transpiration and stomatal conductance contributed to the largest extent, to the discrimination of the wild cherry half-sib lines. In addition, PCA and CDA showed separation of the wild cherry half-sib lines along the first principal component and first canonical variable with regards to humidity of their original sites. Multiple adaptive differences between the wild cherry half-sib lines indicate high potential of the species to adapt rapidly to climate change. The existence of substantial genetic variability among the wild cherry half-sib lines highlights their potential as genetic resources for reforestation purposes and breeding programmes.

Cervical Posture

Background: The present study was conducted in order to determine cervical posture in different skeletal sagittal malocclusions as well as to assess whether a correlation existed between cervical posture and skeletal relationships. Methods: Cervical curvature and inclination of 63 subjects was assessed using their lateral cephalometric radiographs. Cervical inclination was assessed using the cervicohorizontal postural variables namely OPT/HOR and CVT/HOR whereas cervical curvature was determined by measuring the angle OPT/CVT. Sagittally, the subjects were also categorized into skeletal Class I, II and III based on the angle ANB. One way ANOVA was used for the comparison of cervical posture in different skeletal sagittal malocclusions. Pearson’s correlation was used to evaluate the correlation of cervical posture with different skeletal sagittal jaw relations. Statistical significance level was set at p≤0.05. Results: Statistically significant differences were found between the different skeletal malocclusions for the cervical curvature angle OPT/CVT (p=0.025). A weak correlation of cervical curvature angle OPT/CVT (r=0.305, p=0.016) with sagittal malocclusion was found.  Conclusions: Skeletal sagittal malocclusions differ in their cervical postures, especially  cervical curvature. Skeletal Class III subjects have significantly straighter cervical columns than skeletal Class I subjects. Cervical curvature is correlated with sagittal jaw relations.  Keywords: cervical curvature; cervical posture; skeletal sagittal malocclusions .

The aim of this study is to investigate the risk taking status of the recreation department students. The universe of this study consists of students studying at the Recreation Department of the Faculty of Sport Sciences of Fırat University. The sampling on the other hand consists of 130 people who were randomly selected from the Recreation department. The risk taking scale was applied to 130 individuals studying the recreation department and the results obtained were evaluated in the SPSS 22 analysis program. The "Risk Taking Scale", which was first prepared by Weber, Blais and Betz in 2002 and measures individuals' risk taking in terms of moral, social, health, entertainment and financial aspects, was used in the study. The scale was shortened by Weber and Blais in 2006. The scale used in 2006 was used in our study. The reliability value (Cronbach's Alpha Value) in the study is .83. It is measured how much risk individuals are willing to take in five fields specified, according to the scale. After obtaining the research data, SPSS 22.0 statistics package program was used. In the analysis of the data, first of all, whether the data showed normal distribution was examined by Kolmogorov Smirnov test. As a result of the analysis, it was determined that the data showed normal distribution. Frequency %, Independent Samples T Test and One Way Anova Tests were used to evaluate the data of the study. The significance level was determined as P < 0.05 in the analysis. As a result, it was seen in our study that the values of the students studying in the recreation department were above average. In this study conducted on recreation students, it was found that there was no significant difference in terms of risk taking situations. It has been observed that there is not much research done on risk taking in our country. Most of the studies conducted were in the scope of adolescents. There has been scarcely any research, especially on sports and risk taking. For this reason, it is recommended to carry out comprehensive studies on sports and risk.

Microarray gene expression datasets has concerned great awareness among molecular biologist, statisticians, and computer scientists. Data mining that extracts the hidden and usual information from datasets fails to identify the most significant biological associations between genes. A search made with heuristic for standard biological process measures only the gene expression level, threshold, and response time. Heuristic search identifies and mines the best biological solution, but the association process was not efficiently addressed. To monitor higher rate of expression levels between genes, a hierarchical clustering model was proposed, where the biological association between genes is measured simultaneously using proximity measure of improved Pearson's correlation (PCPHC). Additionally, the Seed Augment algorithm adopts average linkage methods on rows and columns in order to expand a seed PCPHC model into a maximal global PCPHC (GL-PCPHC) model and to identify association between the clusters. Moreover, a GL-PCPHC applies pattern growing method to mine the PCPHC patterns. Compared to existing gene expression analysis, the PCPHC model achieves better performance. Experimental evaluations are conducted for GL-PCPHC model with standard benchmark gene expression datasets extracted from UCI repository and GenBank database in terms of execution time, size of pattern, significance level, biological association efficiency, and pattern quality.

ABSTRACT For assessment of the efficacy of surgical hand disinfection, European reference method prEN 12791 prescribes that the hands must be kept wet with the reference alcohol for 3 min regardless of the applied volume. The aim of this study was to determine whether the applied volume of the reference disinfectant n-propanol (60%, vol/vol) influences the effect on the resident hand flora. Ten experiments with 200 reference disinfections were analyzed. Hands were washed for 1 min with soap. The bacterial prevalue was obtained by rubbing fingertips in tryptic soy broth for 1 min. After this, each subject treated the hands with n-propanol (60%, vol/vol) by using as many portions as necessary to keep hands wet for a total of 3 min. Bacterial postvalues (immediate effect) were obtained for one hand, and the other hand was gloved for 3 h. After the gloves were taken off, a second postvalue was obtained (sustained effect). Most surgical reference disinfections (73%) were achieved with 9 ml of the reference alcohol, followed by 12 ml (24%) and 6 ml (3%). There was no significant difference between the mean log10 reduction values for the three treatment groups, both in terms of the immediate effect (P = 0.333, as determined by analysis of variance) and in terms of the sustained effect (P = 0.442). A higher number of portions did not correlate with a higher reduction factor (for immediate effect, Pearson's correlation coefficient = −0.028 [P = 0.689]; for sustained effect, Pearson's correlation coefficient = 0.059 [P = 0.404]). If the hands were kept wet with the reference alcohol for the total application time, the applied volume could vary, but this did not alter the efficacy.

ObjectivesChildren with retinopathy of prematurity (ROP) often have myopia. Even without ROP, birth weight and refractive state are related immediately after birth, but this relationship is reduced with increasing age. Here, we examined whether refractive state and birth weight were associated in 40-month-old children.Methods and analysisOf 541 children aged 40 months in Tsubame City, Japan, who underwent a medical examination between April 2018 and March 2019, this cross-sectional study enrolled 411 whose birth weights were available (76% of all).We measured the non-cycloplegic refraction using a Spot Vision Screener and correlated this with birth weight. Children were divided into three groups according to normal (2500–3500 g), high (>3500 g) or low (<2500 g) birth weights, and mean differences in spherical equivalent (SE) between the groups were analysed.ResultsThe average SE for the right eye was 0.34 D (95% CI 0.28 to 0.40). Average birth weight was 3032.1 g (95% CI 2990.2 to 3073.9). Birth weight did not correlate with SE for the right eye (Pearson’s correlation, r=−0.015, p=0.765) or with the degree of anisometropia (Pearson’s correlation, r=−0.05, p=0.355). Furthermore, the mean SE showed no significant difference across the three groups of children with different birth weights (one-way analysis of variance, p=0.939).ConclusionData on refractive states and birth weight for 411 children of similar age in one Japanese city were analysed, showing that birth weight did not influence SE, J0, J45 and the absolute degree of anisometropia at about 40 months of age.

This study was executed with the aim of investigating whether the perceived freedom levels of students who study in the Faculty of Physical Education and Sports Sciences vary by any variables. The target population of the study composed of 240 voluntary students who study at Kocaeli University, the Faculty of Physical Education and Sports Sciences, 132 (55%) of whom was female and 108 (45%) of whom were male. Perceived Freedom in Leisure Scale, which was developed by Witt and Ellis (1985) and adopted into Turkish by [21] was used as the data collection tool of the study. Kolmogrov-Smirnof test analyzed whether the data showed normal distribution and it was observed that data do not display a normal distribution. As a result of this, Mann Whitney U and Kruskal Wallis H tests were applied. The significance level was considered as 0,05. No significant difference was identified between perceived freedom levels in leisure by means of certain variables such as gender, department, participation in social activities, approximate participation in recreation activities and frequency of leisure participation (p>0,05). A significant difference was found between knowledge and skill – excitement and joy by means of participation in sportive activities, participation in cultural and artistic activities and competence in recreation areas (p<0,05). Consequently, when knowledge and skill – excitement and joy sub-dimensions of students who use their recreational areas, attend to sportive and artistic activities were evaluated, it was seen that individuals who actively participate in any activity may perceive him or herself freer when he or she is compared to the individuals who participate in an activity in a passive way. Therefore, a further activity participation sense may be created.

Objective. To test the inter- and intraexaminer reliability of a recently developed instrument for measuring the maximum bite force (MBF). Material and Methods. Sixty patients who were clinically confirmed as having Oral Submucous Fibrosis (OSMF) and 60 healthy controls were included in this study. For each subject, age, gender, weight, height, and body mass index (BMI) were recorded. The maximum bite force was recorded in alternate order with a bite force sensor (D1) and an occlusal force meter (D2). Bite force was measured in the first molar region. Pearson’s correlation coefficient and kappa statistic were applied to assess the reliability between D1 and D2 in the assessment of maximum bite force. The independent t -test was performed to find the statistical significance between the two study groups. The paired t -test was applied to find out the difference between the right and left disease in groups of two devices separately. The one-way analysis of covariance (ANOVA) was performed to find the significant difference between grades of OSMF. Results. The results of the kappa values were 0.8531 ± 0.0724 and 0.7336 ± 0.0737 for interdevice reliability in OSMF patients in right and left sides. Similar findings were obtained in right and left sides of healthy individuals ( 0.7549 ± 0.0816 and 0.9440 ± 0.0806 ) and in the total sample ( 0.8132 ± 0.0544 and 0.8303 ± 0.0538 ). Pearson’s correlation coefficient between two devices revealed a high and significant positive correlation between D1 and D2 separately and in the whole sample. Conclusion. The observations of the present study suggest that the bite force sensor can be used as a reliable device for measuring bite force.
