This study deals with the one-parameter family {Dq}q∈[0,1]{\left\{{D}_{q}\right\}}_{q\in \left[0,1]} of Bernstein-type operators introduced by Gupta and called the limit qq-Durrmeyer operators. The continuity of this family with respect to the parameter qq is examined in two most important topologies of the operator theory, namely, the strong and uniform operator topologies. It is proved that {Dq}q∈[0,1]{\left\{{D}_{q}\right\}}_{q\in \left[0,1]} is continuous in the strong operator topology for all q∈[0,1]q\in \left[0,1]. When it comes to the uniform operator topology, the continuity is preserved solely at q=0q=0 and fails at all q∈(0,1].q\in \left(0,1]. In addition, a few estimates for the distance between two limit qq-Durrmeyer operators have been derived in the operator norm on C[0,1]C\left[0,1].

Turan, Mehmet Emin
- Abstract
In this study, it was examined whether empathy is related to video game addiction and whether psychological resilience and life satisfaction mediate this relationship. The sample comprised 324 Turkish adolescents (aged between 11 and 15, mean of age was 13.01), who completed measures of empathy, psychological resilience, life satisfaction, and video game addiction. The results of the serial multiple mediation analysis demonstrated that empathy had a significant direct effect on video game addiction. Psychological resilience had a mediating effect on the association between empathy and video game addiction. Also, life satisfaction had a mediating effect on the association between empathy and video game addiction. Psychological resilience and life satisfaction, serially (in combination) mediated the relationship between empathy and video game addiction. The results of the present study are discussed within the related literature. It is suggested that video game addiction interventions should focus on increasing empathy, psychological resilience, and life satisfaction.

Happiness -- Models ,Forgiveness -- Models ,Security (Psychology) -- Models ,Psychology and mental health - Abstract
The ultimate goal of life is happiness, according to Plato. Perhaps the most critical questions in the life of human beings have been on happiness and processes that affect happiness. The present study was planned during the COVID-19 pandemic; perhaps human beings are most needed for happiness. The original hypothetical model and the findings constitute the powerful and different aspects of the present study. This study determined a hypothetical model to examine the relationships among happiness, forgiveness, emotional reactivity, and emotional security. The participant group of the study consists of a total of 916 individuals from Turkey, 617 women, and 299 men. The age scale of the participants is between 18-25. Participants completed the Heartland Forgiveness Scale, the Emotional Security Scale, the Emotional Reactivity Scale, and the Oxford Happiness Scale. Mediation analysis was conducted using Hayes' (2017) process macro. According to the proposed model in the study, emotional reactivity mediates the relationship between forgiveness and happiness. As the individual's forgiveness increases, their emotional reactivity decreases, and as the emotional reactivity decreases, the individual's level of happiness increases., Author(s): Mustafa Ercengiz [sup.1] , Serdar Safali [sup.1] , Alican Kaya [sup.1] , Mehmet Emin Turan [sup.1] Author Affiliations: (1) grid.448590.4, 0000 0004 0399 2543, Faculty of Education, Agri Ibrahim [...]

- Abstract
The present study aims to investigate the relationship between metacognitive awareness and success orientations of physical education and sports teacher candidates. The population of the research consisted of 240 teacher candidates studying in the third and fourth grades in physical education and sports teaching departments at Bozok, Erciyes, and Mehmet Akif Ersoy Universities, and 142 students who were selected with random sampling method consisted the sample group. In the collection of the data, the Personal Information Form, Metacognitive Awareness Inventory and Success Orientation were used. The obtained data were analyzed in the computer environment. Number, percentage, average, and standard deviation were used as descriptive statistical methods in the evaluation of the data. Pearson correlation analysis was used between the continuous variables of the study. As a result, it was determined that the metacognitive awareness of the physical education teacher candidates was low, the learning orientation and the tendency for performance from the sub-headings of success orientation were high and medium, respectively, and the avoid of performance tendency was medium, and there was a low negative relationship between the metacognitive awareness and the avoid of performance tendency which is among the sub-headings of success orientation. It can be stated that this situation originates from the fact that the physical education teacher candidates possess certain levels of sports skills, knowledge and achievements in the sportive life that started and/or still continue before the university education, and from the thoughts of avoiding negative judgments by performing their skills as well as learning new skills.

Frozen sectioning (FS) is the preparation method of choice for microscopic evaluation of tissues during surgical operations. The high speed of the procedure allows pathologists to rapidly assess the key microscopic features, such as tumour margins and malignant status to guide surgical decision-making and minimise disruptions to the course of the operation. However, FS is prone to introducing many misleading artificial structures (histological artefacts), such as nuclear ice crystals, compression, and cutting artefacts, hindering timely and accurate diagnostic judgement of the pathologist. Additional training and prolonged experience is often required to make highly effective and time-critical diagnosis on frozen sections. On the other hand, the gold standard tissue preparation technique of formalin-fixation and paraffin-embedding (FFPE) provides significantly superior image quality, but is a very time-consuming process (12-48 hours), making it unsuitable for intra-operative use. In this paper, we propose an artificial intelligence (AI) method that improves FS image quality by computationally transforming frozen-sectioned whole-slide images (FS-WSIs) into whole-slide FFPE-style images in minutes. AI-FFPE rectifies FS artefacts with the guidance of an attention mechanism that puts a particular emphasis on artefacts while utilising a self-regularization mechanism established between FS input image and synthesized FFPE-style image that preserves clinically relevant features. As a result, AI-FFPE method successfully generates FFPE-style images without significantly extending tissue processing time and consequently improves diagnostic accuracy. We demonstrate the efficacy of AI-FFPE on lung and brain frozen sections using a variety of different qualitative and quantitative metrics including visual Turing tests from 20 board certified pathologists.

- Abstract
This study aimed to analyse the relationship between teaching/learning conceptions and reflective thinking in physical education teacher candidates. To this end, the study recruited, on a voluntary basis, 640 students who were in 1st, 2nd, 3rd and 4th grade in the Department of Physical Education and Sports Teaching in the School of Physical Education and Sports at Erciyes, Ahi Evran, Selcuk and Haci Bektas Veli Universities during the 2017-2018 academic year. As data collection tools, the study used the Teaching/Learning Conception Questionnaire, Reflective Thinking Tendency Scale and Socio-demographic Information Form. The data obtained through the scales was statistically analyzed using SPSS 20.0 software. The candidates' personal information and inventory total points as well as factor points were presented by identifying frequency (f) and percentage (%) values. To indicate the relationship between the scores obtained on the scales, the Pearson Moment Product Correlation analysis (r) was conducted while multiple regression analysis was performed to determine whether the scores are predictive of each other. Consequently, it was found that the traditional conception of teaching and learning has no statistically significant relationship with any subscale of the reflective thinking tendency scale. On the other hand, the study revealed that the constructivist conception of teaching and learning is statistically correlated with reflective thinking in general and with the subscales open-mindedness and interrogative and effective teaching.

- Abstract
The aim of this research is to examine the relationship between the peer pressure levels of prospective teachers and their risk-taking tendencies. In order to achieve this aim, 503 students at Erciyes University studying in the physical education and sports, mathematics, physics, chemistry, classroom, biology, geography and Turkish teaching departments were selected by coincidental methods for this research. To collect data, the students filled out, the 'Peer Pressure Scale' for Peer Pressure Levels (UOI) developed by Kiran Esen (2003), the Risk-Taking Scale developed by Bayar and Sayil (2005), and the "Personal Information Form" prepared by the researcher. The survey data were used to determine the students' risk-taking tendencies. The data obtained from the Personal Information Sheet were analyzed via the SPSS 20.0 package program. The personal information and inventory total scores and factor scores for the candidates were determined by determining the frequency (f) and percentage (%) values. Multiple regression analysis ([beta]) was used to determine whether Pearson Moments Multiplication Correlation analysis (r) and their scores were predictive of each other in order to reveal the relationship between the scores obtained from the scales. Indirect peer pressure and direct peer pressure have significant effects on the risk-taking tendencies of teacher candidates. At the same time, when looking at the general dimension of peer pressure, it was found that it increased the risk-taking tendency significantly and accounted for 38.1% of the total variance.

Current capsule endoscopes and next-generation robotic capsules for diagnosis and treatment of gastrointestinal diseases are complex cyber-physical platforms that must orchestrate complex software and hardware functions. The desired tasks for these systems include visual localization, depth estimation, 3D mapping, disease detection and segmentation, automated navigation, active control, path realization and optional therapeutic modules such as targeted drug delivery and biopsy sampling. Data-driven algorithms promise to enable many advanced functionalities for capsule endoscopes, but real-world data is challenging to obtain. Physically-realistic simulations providing synthetic data have emerged as a solution to the development of data-driven algorithms. In this work, we present a comprehensive simulation platform for capsule endoscopy operations and introduce VR-Caps, a virtual active capsule environment that simulates a range of normal and abnormal tissue conditions (e.g., inflated, dry, wet etc.) and varied organ types, capsule endoscope designs (e.g., mono, stereo, dual and 360{\deg}camera), and the type, number, strength, and placement of internal and external magnetic sources that enable active locomotion. VR-Caps makes it possible to both independently or jointly develop, optimize, and test medical imaging and analysis software for the current and next-generation endoscopic capsule systems. To validate this approach, we train state-of-the-art deep neural networks to accomplish various medical image analysis tasks using simulated data from VR-Caps and evaluate the performance of these models on real medical data. Results demonstrate the usefulness and effectiveness of the proposed virtual platform in developing algorithms that quantify fractional coverage, camera trajectory, 3D map reconstruction, and disease classification., Comment: 18 pages, 14 figures

Computer Science - Computer Vision and Pattern Recognition - Abstract
Deep learning techniques hold promise to develop dense topography reconstruction and pose estimation methods for endoscopic videos. However, currently available datasets do not support effective quantitative benchmarking. In this paper, we introduce a comprehensive endoscopic SLAM dataset consisting of 3D point cloud data for six porcine organs, capsule and standard endoscopy recordings as well as synthetically generated data. A Panda robotic arm, two commercially available capsule endoscopes, two conventional endoscopes with different camera properties, and two high precision 3D scanners were employed to collect data from 8 ex-vivo porcine gastrointestinal (GI)-tract organs. In total, 35 sub-datasets are provided with 6D pose ground truth for the ex-vivo part: 18 sub-dataset for colon, 12 sub-datasets for stomach and 5 sub-datasets for small intestine, while four of these contain polyp-mimicking elevations carried out by an expert gastroenterologist. Synthetic capsule endoscopy frames from GI-tract with both depth and pose annotations are included to facilitate the study of simulation-to-real transfer learning algorithms. Additionally, we propound Endo-SfMLearner, an unsupervised monocular depth and pose estimation method that combines residual networks with spatial attention module in order to dictate the network to focus on distinguishable and highly textured tissue regions. The proposed approach makes use of a brightness-aware photometric loss to improve the robustness under fast frame-to-frame illumination changes. To exemplify the use-case of the EndoSLAM dataset, the performance of Endo-SfMLearner is extensively compared with the state-of-the-art. The codes and the link for the dataset are publicly available at https://github.com/CapsuleEndoscope/EndoSLAM.

Although wireless capsule endoscopy is the preferred modality for diagnosis and assessment of small bowel diseases, the poor camera resolution is a substantial limitation for both subjective and automated diagnostics. Enhanced-resolution endoscopy has shown to improve adenoma detection rate for conventional endoscopy and is likely to do the same for capsule endoscopy. In this work, we propose and quantitatively validate a novel framework to learn a mapping from low-to-high resolution endoscopic images. We combine conditional adversarial networks with a spatial attention block to improve the resolution by up to factors of 8x, 10x, 12x, respectively. Quantitative and qualitative studies performed demonstrate the superiority of EndoL2H over state-of-the-art deep super-resolution methods DBPN, RCAN and SRGAN. MOS tests performed by 30 gastroenterologists qualitatively assess and confirm the clinical relevance of the approach. EndoL2H is generally applicable to any endoscopic capsule system and has the potential to improve diagnosis and better harness computational approaches for polyp detection and characterization. Our code and trained models are available at https://github.com/CapsuleEndoscope/EndoL2H., Comment: 23 pages, submitted to IEEE Transactions on Medical Imaging, corresponding Author: Mehmet Turan

Recent advances in artificial intelligence research have led to a profusion of studies that apply deep learning to problems in image analysis and natural language processing among others. Additionally, the availability of open-source computational frameworks has lowered the barriers to implementing state-of-the-art methods across multiple domains. Albeit leading to major performance breakthroughs in some tasks, effective dissemination of deep learning algorithms remains challenging, inhibiting reproducibility and benchmarking studies, impeding further validation, and ultimately hindering their effectiveness in the cumulative scientific progress. In developing a platform for sharing research outputs, we present ModelHub.AI (www.modelhub.ai), a community-driven container-based software engine and platform for the structured dissemination of deep learning models. For contributors, the engine controls data flow throughout the inference cycle, while the contributor-facing standard template exposes model-specific functions including inference, as well as pre- and post-processing. Python and RESTful Application programming interfaces (APIs) enable users to interact with models hosted on ModelHub.AI and allows both researchers and developers to utilize models out-of-the-box. ModelHub.AI is domain-, data-, and framework-agnostic, catering to different workflows and contributors' preferences.

In the last decade, numerous supervised deep learning approaches requiring large amounts of labeled data have been proposed for visual-inertial odometry (VIO) and depth map estimation. To overcome the data limitation, self-supervised learning has emerged as a promising alternative, exploiting constraints such as geometric and photometric consistency in the scene. In this study, we introduce a novel self-supervised deep learning-based VIO and depth map recovery approach (SelfVIO) using adversarial training and self-adaptive visual-inertial sensor fusion. SelfVIO learns to jointly estimate 6 degrees-of-freedom (6-DoF) ego-motion and a depth map of the scene from unlabeled monocular RGB image sequences and inertial measurement unit (IMU) readings. The proposed approach is able to perform VIO without the need for IMU intrinsic parameters and/or the extrinsic calibration between the IMU and the camera. estimation and single-view depth recovery network. We provide comprehensive quantitative and qualitative evaluations of the proposed framework comparing its performance with state-of-the-art VIO, VO, and visual simultaneous localization and mapping (VSLAM) approaches on the KITTI, EuRoC and Cityscapes datasets. Detailed comparisons prove that SelfVIO outperforms state-of-the-art VIO approaches in terms of pose estimation and depth recovery, making it a promising approach among existing methods in the literature., Comment: 15 pages, submitted to The IEEE Transactions on Robotics (T-RO) journal, under review

- Abstract
The purpose of this study is to examine the effects of pre-service physical education teachers' instructional styles on self-regulation skills. For this purpose, the sample of the research consists of 608 students who were randomly selected among the ones who 4th-grade students continue their education at Physical Education and Sports College in Erciyes, Omer Halisdemir, Aksaray, Dumlupinar, Gaziantep, Firat, Selcuk, Ahi Evran, Inonu, Erzincan and Haci Bektas Veli Universities. In the study, 2 scales were used as data collection tool. The first of these, Instructional Style Preference Scale (ISPS), was developed by Renzulli et al. (2002). The Self-Regulation Skill Scale (SRSS) was developed by Arslan (2008) in order to determine the self-regulation skill levels of pre-service teachers. In addition, personal information forms developed by the researcher were used in the study. Statistical analyses of the data obtained from the Personal Information Form were made with the SPSS 22.0 package program. The personal information and inventory total scores and factor scores for the candidates were given by determining the frequency (f) and percentage (%) values. Pearson Moments Multiplication Correlation analysis (r) was used to show the relationship between scores obtained from the scales. Multiple regression analysis ([beta]) was applied to determine whether the scores obtained were predictive of each other. A significant relationship was found between the discussion, which is among the instructional styles, cognitive regulation sub-dimension and the programmed instruction. It has been found that there is a high level of correlation between the effort regulation sub dimension and the straight narration between the instructional styles. In addition, there was a significant positive correlation between the subscale of the organization of the study and the literal expression between the instructional styles. When the results of the study were examined, it was thought that, generally, those who are aware of and make use of the learning styles have higher self-regulation skills than those who do not pay attention to the use of instructional style and are more successful in terms of academic achievements.

- Abstract
In this study, it is aimed to investigate the partial mediating effect of ego identity status and personality traits on general self-efficacy levels of physical education and sports teacher candidates. To do that, a model showing possible relationships between these variables was established and this model was tested by using structural equation modeling. The sample of the study consisted of 578 students in the freshmen, sophomore, junior, and senior years in the Physical Education Sports Teaching Departments of universities Erciyes, Mehmet Akif, Dumlupinar, and Ahi Evran. The Socio-Demographic Information Form created by the researchers, General Self-Efficacy Scale adapted to Turkish by Aypay (2010), Ego Identity Status Scale adapted by Oskay (1998), and Eysenck Personality Questionnaire adapted to Turkish by Karanci et al. (2007) were used as the data collection tools. SPSS 22 program and Structural Equation Modeling/AMOS/Path Diagram program were used for data analysis. Firstly, the measurement models were tested and the proposed measurement model proved to be able to use to test the structural model. The structural model proposed based on the validated measurement models were then tested and verified. The fit indices of the model established in the study were found to be good and the coefficients obtained were found to be statistically significant. According to the results obtained about the structural model, it was found that there was a significant relationship between the general self-efficacy with ego identity status and personality traits, and that the ego identity status and personality traits predict the general self-efficacy in an advanced level. As a result, it is thought that the general self-efficacy levels of the students will increase with the positive development of ego identity status and personality traits, and this increase will enable the students to increase their academic achievement and self-confidence, as well as will make them more active in the society.

- Abstract
This study aims to examine the impact of cultural intelligence on social skills among the students of the School of Physical Education and Sports. The research population consists of randomly selected 377 students. As data collection tools, the study uses Cultural Intelligence Scale, Social Skills Inventory and "Personal Information Form." The data obtained through the Personal Information Form, Cultural Intelligence Scale and Social Skills Inventory was statistically analyzed using SPSS 20.0 package program. The information about and inventory total scores of the candidates and factor points were presented by finding frequency (f) and percentage (%) values. Pearson Moment Correlation Coefficient analysis (r) was performed to indicate the relationship between the points obtained from the scales while multiple regression analysis was performed to identify whether the points are predictor of each other. (ß) In the study, we found positive significant relationships between cultural intelligence dimensions--cognitive, metacognitive, motivational and behavioural skills--and social skills dimensions--emotional expressivity, emotional sensitivity, emotional control, social expressivity, social sensitivity and social control. An examination of the prediction of social skills by cultural intelligence reveals that cognitive, metacognitive, motivational and behavioural dimensions are predictor of social skills, and students' social skills improve with the increase in their cultural intelligence level. Consequently, the significance of cultural intelligence and social skills is increasingly growing for maintaining successful, healthy and peaceful relationships between people. Individuals with higher cultural intelligence and sociability are expected to be more active in the education system while having a high level of willingness in learning activities. Particularly in the universities where various cultures coexist, students who can establish social relationships with their friends and professors will be more successful and enthusiastic about accepting positions to participate in international activities. The development of cultural intelligence and social skills will naturally improve students in social and cultural aspects, thus contributing to form the basis of a healthier world. For these reasons, it will be useful to provide training that enhance social skills in educational and training settings and carry out activities that increase interaction with other cultures such as student exchange programs and overseas educational tours in order to enhance cultural intelligence level.

- Abstract
The aim of this study was to examine the impact of self-directed learning readiness on critical thinking and general self-efficacy among the students of the School of Physical Education and Sports. In line with this aim, the research sample consisted of 419 students who were randomly selected from the School of Physical Education and Sports in Erciyes University. To collect data, the study used Self-Directed Learning Readiness Scale, Critical Thinking Scale, General Self-Efficacy Scale and 'Personal Information Form' created by the researcher. The data obtained through the Personal Information Form was statistically analyzed using SPSS 20.0 package program. The candidates' personal information and inventory total scores and factor points were presented by calculating frequency (f) and percentage (%) values. Pearson Moment Correlation Coefficient analysis (r) was performed to indicate the relationship between the points obtained from the scales while multiple regression analysis was performed to identify whether the points are predictor of each other. (ß) The study found a positive significant relationship between self-directed learning readiness and critical thinking. A positive significant relationship was also found between self-directed learning readiness and general self-efficacy. Finally, there was a positive high relationship between general self-efficacy and critical thinking. The results of the study suggest that self-directed learning readiness affects critical thinking and general self-efficacy characteristics as it influences other aspects related to education. Self-directed learning readiness predicts critical thinking and general self-efficacy by 50.5%. Hence, authentic environments should be created to improve students' self-directed learning readiness when preparing education and training programs especially as a significant aspect of modern education systems in today's world.

- Abstract
In today's changing and developing world, the most important elements that enable people to live together in society are values. The education of such values start in the family and the social environment that they are in, from the moment a person is born and do continue in school as the child starts to study. Schools teach values to their students through the programs they practice. One of the most important courses that these values are taught is the social sciences. Social sciences, which is formed to prepare the students for social life is also one of the fundamental courses for the education of values. This study was carried out in order to review the values taught in the 4th grade social science course program, from the vantage point of the teachers. In order to realize this, the achievements in the program were determined and a survey form was created. The study is in a screening model and is descriptive. The study group of the study is composed of 199 classroom teachers working in the province of Elazig in the academic year of 2016-2017. The data obtained from the research is analyzed using "arithmetic mean" "percentage" and "frequency"; The degree of influence of teacher opinions on variables based on demographic data was also tested using independent t test. According to the results of the research, teachers think that levels of most of the values taught in social sciences course fit the level of understanding of the students.

Turan, Mehmet and Bayar, Betül
- Abstract
The purpose of the two-teacher primary teaching model is to find a solution, to some extent, for the crowded classes and the classes in which the inclusive students study in primary school. Furthermore, it is aimed to increase the efficiency of the lessons, better take care of the inclusive students, implement the constructivist approach as required, collect the attention of the students who lost their attentions, support students who have difficulties in their studies, ensure that students who learn slowly can learn the lessons completely and increase the quality of education by giving additional studies to the students who learn quickly. The co-teaching model that can be considered as an alternative in solution of the educational problems can be used effectively in the crowded classes and the classes in which the inclusive students study. Moreover, this study can be considered as an alternative model so that the "Teaching Practice" lessons taken by the teacher candidates studying at the education faculty can be more qualified and efficient. The purpose of this study is to review the effectiveness of teaching practice in primary school based on co-teaching model. In this context, it was tried to determine the opinions of primary school teachers about the co-teaching model. To achieve this purpose, 12 primary teachers serving in the city center of Mus were determined as working group. In the study, the data were obtained by semi-structured interview method. Content analysis was used for the analysis of the data. According to the teachers' opinions obtained as a result of the study, the most important one of the problems experienced by the teachers during the teaching period is the crowded classes. It is concluded that in the crowded classes, the activities are not implemented at the desired level, it is not possible to allocate enough time for the students, incorrect and incomplete learning of students cannot be realized on time and it is difficult to give a student-centered education. As a result of the study, in order to ensure that the teaching practice can be efficient, it is concluded that the internship duration should be extended, the teacher candidates should be assigned more responsibilities, the teacher candidates should do internships in the rural schools and combined classes so that they can see different environments and they should carry out implementation-oriented studies rather than observation-oriented studies in this lesson. According to the teachers' opinions obtained as a result of the study, it is concluded that the co-teaching model will increase the efficiency of the lesson, the classroom management will be easier, this model will ensure that the students who fall behind and learn slowly can learn the lessons completely, the saving on time will be ensured, the opportunity to take care of students personally will increase, the workload of the teachers will decrease, the equal opportunity in education will be ensured by taking care of the inclusive students more than before and the faster and more practical solutions will be created for the problems to be encountered in the teaching process.

- Abstract
The aim of this study is to examine the association between factors hindering the participation of university students in recreational activities and their leisure motivations. The students (800) of the Erciyes University in 2014-2015 academic year became involved voluntarily in the research. The volunteers participating in the research filled the socio-demographic information form including their personal information; then, "Leisure Barriers Scale" and "Leisure Motivation Scale" were applied to them. The package statistics program of IBM SPSS (Statistical Package for the Social Sciences) 20 was employed in analyzing the data. The arithmetic mean and standard deviation of scores the university students got from the scales of Leisure Barriers and Leisure Motivation were presented as X±SS. In order to disclose the relationship between the data obtained from two scales, Pearson Product-Moment Correlation Analysis was applied. The significance level was accepted as p<0.05. In conclusion, it was found that the leisure motivations and the participation in recreational activities of students are at middle level. It was detected that there is a positive significant correlation among the subdimensions of leisure motivations and barriers. University students should benefit from recreational activities during the time left from their studies and from the time spent for vital needs, in order to solve material and moral problems, socialize, enhance and share cultural and knowledge accumulation, and be healthy physically, spiritually, and mentally. Thereby, students would achieve success more easily in socio-cultural and professional life. For this reason, universities should arrange the recreational areas such as cultural, artistic, sportive ones, and multiply the recreational activities in line with students' needs.

Robust indoor ego-motion estimation has attracted significant interest in the last decades due to the fast-growing demand for location-based services in indoor environments. Among various solutions, frequency-modulated continuous-wave (FMCW) radar sensors in millimeter-wave (MMWave) spectrum are gaining more prominence due to their intrinsic advantages such as penetration capability and high accuracy. Single-chip low-cost MMWave radar as an emerging technology provides an alternative and complementary solution for robust ego-motion estimation, making it feasible in resource-constrained platforms thanks to low-power consumption and easy system integration. In this paper, we introduce Milli-RIO, an MMWave radar-based solution making use of a single-chip low-cost radar and inertial measurement unit sensor to estimate six-degrees-of-freedom ego-motion of a moving radar. Detailed quantitative and qualitative evaluations prove that the proposed method achieves precisions on the order of few centimeters for indoor localization tasks., Comment: Submitted to IEEE Sensors, 9pages

Given random variables $X$ and $Y$ having finite moments of all orders, their uncorrelatedness set is defined as the set of all pairs $(j,k)\in{\mathbb N}^2,$ for which $X^j$ and $Y^k$ are uncorrelated. It is known that, broadly put, any subset of ${\mathbb N}^2$ can serve as an uncorrelatedness set. This claim ceases to be true for random variables with prescribed distributions, in which case the need arises so as to identify the admissible uncorrelatedness sets. This paper studies the uncorrelatedness sets for positive random variables uniformly distributed on three points. Some general features of these sets are derived. Two related Vandermonde-type determinants are examined and applied to describe uncorrelatedness sets in specific cases., Comment: 16pages

- Abstract
Adolescence is a period that plays a crucial role in career development. Understanding the psychological structures associated with a career can help to better understand adolescents' career development. The aim of this study was to examine the mediating role of career and talent development self-efficacy in the relationship between adolescents' locus of control and the construct of children's hope. The study group was composed of 354 adolescents including 170 females and 184 males. The mean age of participants was 14.3 years. Structural equation modelling was used to investigate the mediating role of career and talent development self-efficacy in the relationship between locus of control and children's hope. It was concluded that career and talent development self-efficacy had a mediating role in the relationship between locus of control and children's hope. Mental health professionals and educators who carry out locus of control or hope-based interventions are recommended to pay attention to the mediating role of self-efficacy.
