Effective training of competent specialists in a contemporary university requires the disclosure of personal abilities and internal potential of students who realize themselves as subjects of learning activity. The problem of studying the psychological factors of enhancing learning and self-realization of students in the educational space is of particular relevance. The hypothesis of the study was the assumption about the influence of motivational, personal-orientation and life-sense factors on the level of students' self-realization in university education. The study involved 224 students of the 4-5th courses from Belgorod National Research University and Belgorod State Technological University named after V.G. Shukhov. The author’s questionnaire for identifying the degree of students' self-realization in learning, as well as questionnaires and tests known in psychology for identification of motivational, personal and sense-purpose characteristics, served as diagnostic tools. The results were processed using cluster analysis, Student's t-test and Spearman's rank correlation coefficient. As a result it turned out that students with varying degrees of self-realization in education had differences in personal characteristics. Students with stable self-realization had higher scores for such motivational parameters as: attitude to learning (t = 7.056, p ≤ 0.001), self-expression need (t = 3.08, p = 0.003), satisfaction of achievements (t = 5.33, p ≤ 0.001). Meanwhile, students with low self-realization had an increased safety need (t = 2.26, p = 0.016). According to personal orientations and self-attitude, students with articulated self-realization were characterized by higher scores in terms of self-regard (t = 2.77, p = 0.007), self-management (t = 4.34, p ≤ 0.001), reflected self-attitude (t = 3.18, p = 0.002) and self-esteem (t = 3.02, p = 0.005). With regard to life-sense orientations, students with stable self-realization were distinguished by higher values of internal locus of control t = 4.50, p ≤ 0.001), life management (t = 4.07, p ≤ 0,001), life productivity (t = 3.84, p ≤ 0.001) and interesting eventful life (t = 3.80, p ≤ 0.001). Based on the correlation analysis, a number of positive relationships of self-realization markers in according to the questionnaire with personal characteristics of students were revealed. A positive connection was remarked between attitude to learning and following markers: the intention to work intensively in the classes (r = 0.52, p ≤ 0.01), recognizing of the usefulness of learning for oneself (r = 0.50, p ≤ 0.01), minimal learning frustration (r = 0.49, p ≤ 0.01). Satisfaction of knowledge correlated with markers of achieving a better self-knowledge (r = 0.49, p ≤ 0.01) and developing of personal abilities (r = 0.48, p ≤ 0.01). Self-management correlates with marker of achieving a deeper self-understanding (r = 0.47, p ≤ 0.01). Thus, the study made it possible to present the differentiated personal characteristics of students with different levels of self-realization in learning. The results can be useful for improving university practice in creating psychological and pedagogical conditions for a more complete students’ self-realization in the training process.

Aim. The main aim of the research was to evaluate and compare changes in accuracy of throws performed by KS Cracovia 1906 handball players, before and after endurance effort. Basic procedures. The study was carried out among14 players who played in the second women’s handball division in the 2016/2017 season. The study took place during final preparations for the season, at the beginning of September 2016. The level of durability of the tested players was assessed using the Beep Test and the accuracy of throws, both before and after the endurance effort (after the Beep Test), was analysed, considering the training and endurance experience of the tested handball players. Basic methods of descriptive statistics, the Student’s t-test and Spearman’s rank correlation coefficient were used in the preparation of the results, and to assess the size of differences between the individual players, normalised indicators were calculated. Results main findings. Analysis of the research results presented in the study showed that after a long-term effort of endurance nature, the accuracy of throws among the tested handball players decreased. It seems that they suffered from nervous system fatigue leading to less accurate and less precise performance of motor tasks. Conclusions. On the basis of the analysis performed in the study, the following conclusions were drawn: that the accuracy of throws among KS Cracovia 1906 handball players after a long endurance effort, significantly decreased, and the accuracy of throws, both before and after the endurance effort, does not depend on the training period. Furthermore, more time should be devoted to the formation of aerobic strength in training the tested team.

BACKGROUND Breast cancer has a high incidence rate among women in Taiwan and worldwide. Advanced surgery and medical therapies have improved survival rates. Today, smartphones are popular and can be used to develop ubiquitous technology for disease self-management and to maintain patients’ quality of life. In Taiwan, a mobile health self-management support app with eight main features was developed to address breast cancer women’s information needs based on prior research using a design thinking approach. OBJECTIVE The aim of this study was to pilot test Taiwan breast cancer women’s acceptance of the app. METHODS An instrument with confirmed reliability and validity based on the modified technology acceptance model for mobile services and aesthetics preference of interface icons was used. Women with breast cancer were recruited to participate in the pilot test workshop and then answer survey questionnaires. Descriptive statistics and Spearman’s rank correlation coefficient method was used to analyze the data. RESULTS A total of 45 women participated the study. They were mostly aged 41-50(40%, 18/45), bachelor’s degree or equivalent (54.4%, 29/45), married (66.7%, 30/45), stage II breast cancer (37.8%, 17/45), had completed treatment (55.6%, 25/45) and received surgical treatment (93.3%, 42/45). The highest mean scores of user acceptance factors rated on the 5-point Likert scale was perceived ease of use (4.14, SD=0.42), followed by actual use (4.12, SD=0.57), perceived value (4.07, SD=0.62), user satisfaction (4.01, SD=0.51), intention to use (3.89, SD=0.58), and the lowest mean score was trust (3.89, SD=0.58). The Spearman’s rank correlation coefficient indicated positive associations between each factor and statistically significant correlations (p value <0.05). Seven of eight interface feature icons in original app were favored over alternative icon options. CONCLUSIONS This study developed a smartphone app to predict Taiwan breast cancer women’s acceptance of mobile health technology for supporting disease self-management. The results suggest that patients positively accepted the app and would like it to be available in the future. However, data security and individual privacy protection features should be enhanced to increase users’ trust. In addition, the design of most interface icons was accepted by the participants which is consistent with their perceived ease of use of the app.

Abstract Background Type 2 diabetes mellitus (T2DM) is mainly affected by genetic and environmental factors; however, the correlation of long noncoding RNAs (lncRNAs) with T2DM remains largely unknown. Methods Microarray analysis was performed to identify the differentially expressed lncRNAs and messenger RNAs (mRNAs) in patients with T2DM and healthy controls, and the expression of two candidate lncRNAs (lnc-HIST1H2AG-6 and lnc-AIM1-3) were further validated using quantitative real-time polymerase chain reaction (qRT-PCR). Spearman’s rank correlation coefficient was used to measure the degree of association between the two candidate lncRNAs and differentially expressed mRNAs. Furthermore, the KEGG (Kyoto Encyclopedia of Genes and Genomes) pathway and GO (Gene Ontology) enrichment analysis were used to reveal the biological functions of the two candidate lncRNAs. Additionally, multivariate logistic regression analysis and receiver operating characteristic (ROC) curve analysis were performed. Results The microarray analysis revealed that there were 55 lncRNAs and 36 mRNAs differentially expressed in patients with T2DM compared with healthy controls. Notably, lnc-HIST1H2AG-6 was significantly upregulated and lnc-AIM1-3 was significantly downregulated in patients with T2DM, which was validated in a large-scale qRT-PCR examination (90 controls and 100 patients with T2DM). Spearman’s rank correlation coefficient revealed that both lncRNAs were correlated with 36 differentially expressed mRNAs. Furthermore, functional enrichment (KEGG and GO) analysis demonstrated that the two lncRNA-related mRNAs might be involved in multiple biological functions, including cell programmed death, negative regulation of insulin receptor signal, and starch and sucrose metabolism. Multivariate logistic regression analysis revealed that lnc-HIST1H2AG-6 and lnc-AIM1-3 were significantly correlated with T2DM (OR = 5.791 and 0.071, respectively, both P = 0.000). Furthermore, the ROC curve showed that the expression of lnc-HIST1H2AG-6 and lnc-AIM1-3 might be used to differentiate patients with T2DM from healthy controls (area under the ROC curve = 0.664 and 0.769, respectively). Conclusion The profiles of lncRNA and mRNA were significantly changed in patients with T2DM. The expression levels of lnc-HIST1H2AG-6 and lnc-AIM1-3 genes were significantly correlated with some features of T2DM, which may be used to distinguish patients with T2DM from healthy controls and may serve as potential novel biomarkers for diagnosis in the future.

We previously reported that superficial non-ampullary duodenal tumors (SNADETs) commonly had a whitish mucosal surface, named milk-white mucosa (MWM). The aim of this study was to evaluate the association of MWM with epithelial intracellular lipid droplets (immunohistochemically stained by adipose differentiation-related protein (ADRP)) and histological tumor grades. We reviewed endoscopic images and the histopathology of SNADETs resected en bloc endoscopically. We analyzed the correlation between the positive rates of endoscopic MWM in preoperative endoscopy and resected specimens, and ADRP-positive rates in the resected specimens. Associations between the MWM-positive rates and tumor grades, high-grade intraepithelial neoplasia (HGIN)/intramucosal carcinoma (IC), and low-grade intraepithelial neoplasia (LGIN) were analyzed. All the 92 SNADETs analyzed were <20 mm and histologically classified into 39 HGIN/IC and 53 LGIN. Spearman’s rank correlation coefficient showed a significant correlation between MWM-positive and ADRP-positive rates (p < 0.001). MWM-positive rates were significantly lower in the HGIN/IC than in the LGIN in preoperative endoscopy (p < 0.001) and resected specimens (p = 0.02). Our results suggest that endoscopic MWM is closely associated with epithelial intracellular lipid droplets and that the MWM-positive rate may be a predictor of histological grade in small SNADETs.

Summary Introduction: Hyperplasia of the pharyngeal tonsil is one of the main causes of mouth breathing, and accurate diagnosis of this alteration is important for proper therapeutic planning. Therefore, studies have been conducted in order to provide information regarding the procedures that can be used for the diagnosis of pharyngeal obstruction. Objective: To verify the correlation between nasopharyngoscopy and cephalometric examinations in the diagnosis of pharyngeal tonsil hyperplasia. Method: This was a cross-sectional, clinical, experimental, and quantitative study. Fifty-five children took part in this study, 30 girls and 25 boys, aged between 7 and 11 years. The children underwent nasofibropharyngoscopic and cephalometric evaluation to determine the grade of nasopharyngeal obstruction. The Spearman's rank correlation coefficient at the 5% significance level was used to verify the correlation between these exams. Results: In the nasopharyngoscopy evaluation, most children showed grade 2 and 3 hyperplasia of the pharyngeal tonsil, which was followed by grade 1. In the cephalometry assessment, most children showed grade 1 hyperplasia of the pharyngeal tonsil, which was followed by grade 2. A statistically significant regular positive correlation was observed between the exams. Conclusion: It was concluded that the evaluation of the pharyngeal tonsil hyperplasia could be carried out by fiber optic nasopharyngoscopy and cephalometry, as these examinations were regularly correlated. However, it was found that cephalometry tended to underestimate the size of the pharyngeal tonsil relative to nasopharyngoscopy.

Introduction. The use of age- and risk-adjusted caries prevention requires up-to-date knowledge on the cariostatic effects of fluoride, as well as the methods and safety of fluoride prophylaxis. Aim. The aim of the study was to assess dentists’ knowledge of the safety and mechanism of anticaries effects of fluoride. Material and methods. An anonymous questionnaire was conducted among 212 dentists participating in dental training. The questions included in the questionnaire related to knowledge about water fluoridation, fluoride cariostatic mechanisms and the safety of fluoride prophylaxis. The chi-square test and the Spearman’s rank correlation coefficient were used for statistical analysis. A significance level of 0.05 was used. Results. Incorrect knowledge about water fluoridation was demonstrated by 26.9% of respondents in the country and 16.0% of respondents in Europe. Most respondents (80.7%) reported higher efficacy of exogenous vs endogenous anticaries approaches, and more than half of respondents (59.0%) considered the processes of remineralisation and demineralisation as the most important anticaries activity. Almost all respondents (95.7%) agreed that the use of fluoride for caries prevention is controversial, mainly due to its dose-dependent therapeutic or toxic effects (85.4%). According to about 20% of respondents, cariostatic fluoride doses have adverse effects on the general health, mainly in the form of bone fragility (10.4%). Conclusions. Lack of correct knowledge about the dominant cariostatic effects of fluoride may result in the choice of an inappropriate preventive method or avoiding local application of fluoride preparations for fear of adverse systemic effects, which may in turn lead to increased caries prevalence in a given population.

The Status

To scientifically and accurately evaluate the status of the development of green airports in China, evaluation methods of green, ecological airports are established in this paper. To address the shortcomings in subjective and objective weighting methods, we propose a combination weighting method based on Spearman’s rank correlation coefficient and evaluation grades based on interval approximation. At the same time, by taking into account resource conservation, environmental friendliness, operation efficiency, and people-oriented service, we propose an evaluation index system and an interval number for each index. Lastly, the theory is applied to five large airports in different regions of China. Analysis of the evaluation results shows that Shanghai Pudong International Airport (PVG) and Guangzhou Baiyun International Airport (CAN) have the highest scores for the resource conservation and environmental friendliness indexes, thus indicating that the development of a green ecological airport is closely related to its passenger transportation scale and economic strength. All considered airports showed the need for upgrading public  service facilities and constructing intelligent equipment. The method proposed in this paper is reasonable  and reliable; therefore, it can provide guidance for the evaluation and construction of green, ecological  airports.

The Relationship

Purpose: to determine the relationship between the performance of basic elements and indicators of static and dynamic balance in the training process of young acrobats 6-7 years. Material and methods. The study involved 16 young acrobats at the stage of initial training (age 6-7 years). All parents of the participants gave written consent for the participation of children in the study. The study involved testing the technique of performing basic elements of sports acrobatics and assessing the static and dynamic balance of young athletes. The relationship between (swallow, shoulder blade, forward squat, wheel (sideways overturning), bridges) and static and dynamic equilibrium tests was determined. Spearman's rank correlation coefficient method was used as a method of statistical analysis. Results. It is established that the largest relationship between the performance of basic elements and static balance in the basic exercises of young acrobats have: Romberg's test with the elements "Swallow", "Stand on the shoulders", "Bridge"; Biryuk test with elements "Swallow", "Wheel", "Bridge"; balance "Swallow" with elements "Swallow", "Wheel"; static equilibrium test with the elements "Swallow", "Rack on the shoulders", "Rolling forward with a squat", "Wheel". Reliable values ​​of the correlation coefficient were established between the tests of dynamic balance and the basic elements of sports acrobatics in young athletes 6-7 years, namely: "Swallow", "Flip forward with a squat", "Wheel" and "Bridge". The analysis of special tests of static and dynamic balance in mastering the basic elements of acrobatics at the first stage of long-term training makes it possible to use them to determine the level of coordination capabilities of young athletes and further improve the use of acrobatic exercises. Conclusions. A reliable relationship between the performance of basic exercises and indicators of static and dynamic balance in young acrobats at the initial stage of training. It is shown that the level of static and dynamic balance is of great importance for the assimilation and improvement of basic elements of technology by young acrobats 6-7 years. Static and dynamic balance tests can be used to individually build training programs and young acrobats. It is shown that sports acrobatics is a significant means of developing the balance of children 6-7 years.

Chest X Ray

Recent literature has reported that radiological features of coronavirus disease (COVID-19) patients are influenced by computed tomography. This study aimed to assess the characteristic chest X-ray features of COVID-19 and correlate them with clinical outcomes of patients. This retrospective study included 120 COVID-19 patients. Baseline chest X-rays and serial chest X-rays were reviewed. A severity index in the form of maximum radiological assessment of lung edema (RALE) score was calculated for each lung, and scores of both the lungs were summed to obtain a final score. The mean ± standard deviation (SD) and frequency (%) were determined, and an unpaired t test, Spearman’s rank correlation coefficient, and logistic regression analyses were performed for statistical analyses. Among 120 COVID-19 patients, 74 (61.67%) and 46 (38.33%) were males and females, respectively; 64 patients (53.33%) had ground-glass opacities (GGO), 55 (45.83%) had consolidation, and 38 (31.67%) had reticular-nodular opacities, with lower zone distribution (50%) and peripheral distribution (41.67%). Baseline chest X-ray showed a sensitivity of 63.3% in diagnosing typical findings of SARS-CoV-2 pneumonia. The maximum RALE score was 2.13 ± 1.9 in hospitalized patients and 0.57 ± 0.77 in discharged patients ( p value <0.0001). Spearman’s rank correlation coefficient between maximum RALE score and clinical outcome parameters was as follows: age, 0.721 ( p value <0.00001); >10 days of hospital stay, 0.5478 ( p value <0.05); ≤10 days of hospital stay, 0.5384 ( p value <0.0001); discharged patients, 0.5433 ( p value <0.0001); and death, 0.6182 ( p value = 0.0568). The logistic regression analysis revealed that maximum RALE scores (0.0932 [0.024–0.367]), (10.730 [2.727–42.206]), (1.258 [0.990–1.598]), and (0.794 [0.625–1.009]) predicted discharge, death, >10 days of hospital stay, and ≤10 days of hospital stay, respectively. The study findings suggested that the RALE score can quantify the extent of COVID-19 and can predict the prognosis of patients.
