ABSTRACT
The aim of this research is to examine the effect of online learning attitudes on online learning readiness of sports sciences students during the period of coronavirus pandemic (covid-19). The research was designed with the correlational survey model. The population of research consisted of sports sciences students from the faculty in seven state universities in Turkey. The sample consisted of 599 (271 female + 328 male) sports sciences students studying at the Departments of Coaching Training, Physical Education and Sports Teaching, Recreation and Sports Management, selected by the easy sampling method from these faculties and taking courses from the online learning platform. Data in the research was collected by using "Online Learning Attitude Scale", "Online Learning Readiness Scale", and "Personal Information Form". The data was analyzed using descriptive statistics, Pearson's correlation and regression analysis. According to the research findings;There is a moderately significant positive correlation between online learning attitude and online learning readiness (p <.05). Also, online learning attitude was found to have a significant effect on online learning readiness (p <.05). As a result;In the field of sports sciences, the necessity of establishing a positive online attitude and creating a basis for a successful online learning readiness to provide a good online learning to the learner has been put forward.

ABSTRACT
Novel transition metal-based complexes that may be of value as biological agents and/or nonlinear optical materials, Zn (II) and Cu (II) transition metal complexes of 6-chloropyridine-2-carboxylic acid (LH), were successfully synthesized. The chemical structure of each complex was characterized using X-ray diffraction (XRD) method and FT-IR spectroscopy. XRD and FT-IR demonstrated that L ligand coordinate to central metal ions through the donor N and O atoms. By coordinating two H2O ligand to Zn (II) ion, a distorted octahedral complex geometry was constructed for 1. As for 2, a distorted trigonal bipyramidal coordination geometry was obtained by a H2O ligand coordination to Cu (II) ion. Theoretical studies using B3LYP/6-311++G(d,p)-LanL2DZ were performed to further validate the proposed structures. The molecular docking of 1 to SARS-CoV-2 main protease (PDB: 6LU7) gives a binding energy of −5.24 kcal/mol and inhibition constant of 144.6 μM, demonstrating that 1 is a more promising candidate to biologically active complexes than 2. The first-order hyperpolarizability (β) parameter for 1 and 2 was calculated as 0.88 × 10−30 and 10.40 × 10−30 esu, respectively. These β values also demonstrated that 2 exhibits more effective NLO character than 1 due to the electronic configuration and coordination geometry. © 2022 John Wiley & Sons, Ltd.
ABSTRACT
Aim: The purpose of this study is to determine the state-trait anxiety of athletes during Covid-19 pandemic. Method: The study was performed by using survey method. The research population is composed of a total of 224 adult athletes (Xage=26.24±8.50) as 139 males (Xage=27.71±9.81) and 103 females ( Xage=24.25±5.72) engaged in individual and team sports in different branches in Marmara region (Istanbul, Kocaeli and Sakarya). The athletes have 13.73±8.65 years of experience in sports. "State-Trait Anxiety Inventory" developed by Spielberger et al. (1970) and adapted into Turkish by Oner and Le Compte (1983) and "Personal Information Questionnaire" prepared by the researchers were used as the data collection tool. Data were analyzed by using descriptive statistics, independent groups T-test, one-way variance (ANOVA) analysis and Pearson correlation analysis. Findings: State anxiety scores of athletes significantly differ by such conditions as being a national athlete, fear of Covid infection, damaged performance in Covid infection, doing exercise at home during Covid infection and weight change during Covid (p<.05) while they do not significantly differ by gender and monthly income perception (p>.05). Trait anxiety scores of athletes significantly differ by being a national athlete, fear of Covid infection, damaged performance in Covid infection, doing exercise at home during Covid infection, monthly income perception and weight change during Covid (p<.05) while they do not significantly differ by gender (p>.05). Moreover, significant negative relationship was established between state anxiety scores of athletes and the time of exercise during pandemic (p<.05) while no significant relation was found regarding age, year of sports and duration of sleep during pandemic (p>.05). Negative significant relationships were found between trait anxiety scores and age, year of sports, and time and day of exercise;positive significant relationships were found between trait anxiety and duration of sleep in pandemic period (p<.05). Conclusion: It has been concluded that state anxiety scores of athletes are over average, their trait anxiety scores are below average and state-trait anxiety scores differ by some demographic variables while they are in relation with some others.
