Published: September 2021

Complex disturbance patterns take place over the corresponding power supply networks due to the increased complexity of electrical loads at industrial plants. Such complex patterns are the result of a combination of simpler standardized disturbances. However, their detection and identification represent a challenge to current power quality monitoring systems. The detection of disturbances and their identification would allow early and effective decision-making processes towards optimal power grid controls or maintenance and security operations of the grid. In this regard, this paper presents an evaluation of the four main techniques for novelty detection: k-Nearest Neighbor, Gaussian Mixture Models, One-Class Support Vector Machine, and Stacked Autoencoder. A set of synthetic signals have been considered to evaluate the performance and suitability of each technique as an anomaly detector applied to power quality disturbances. A set of statistical features have been considered to characterize the power line. The evaluation of the techniques is carried out throughout different scenarios considering combined and single disturbances. The obtained results show the complementary performance of the considered techniques in front of different scenarios due to their differences in the knowledge modelization.

Authors: Rubio-Clemente A  , Aguilar J  , Chica E
Published: September 2021

The hydrodynamic performance and the flow field of two horizontal-axis hydrokinetic turbines with and without a high-lift hydrofoil with a flap were investigated using computational fluid dynamics (CFD) simulation. For improving the accuracy of the numerical simulation, the user-defined function (UDF) of 6-degrees of freedom (6-DoF) was used in the Ansys Fluent software. Unsteady Reynolds-averaged Navier–Stokes (URANS) equations coupled to the SST ???? − ???? turbulence model were employed during the simulation. A three-dimensional model of both of the turbines with three blades was conducted for obtaining the performance curve of the power coefficient (????????) versus the tip speed ratio (TSR). The maximum power coefficients (????????????????????) of the hydrokinetic turbines with and without a high-lift hydrofoil arrangement were 0.5050 and 0.419, respectively. Experimental data from the literature were used for the validation of the numerical results, specifically for the case when a rotor with traditional blades is utilized. In general, the simulation results were in good agreement with the experimental data.

Authors: STRAVA CRISTIAN-COSMIN , ORAVIȚAN MIHAELA , MONEA DAN
Published: September 2021

Childhood and adolescent obesity becomes a worldwide health problem, as for the past years the prevalence of obesity amongst youngsters has reached very high levels. The increased levels of obesity at younger age rises concern at a global basis, therefore the prevalence of childhood obesity sets enormous pressure on healthcare system. Obesity is a complex trait influenced not only by genetic factors, but also by other such as: physical inactivity and unhealthy diet or overeating as well as weight status misperception. Some of the measures needed to overcome these factors is that the intervention programs used to prevent or combat obesity, must include assessment and correction of these factors, as well as monitoring their evolution over time. Questionnaires are efficient instruments that can be used for the evaluation of such parameters. This study aims to revise the scientific literature, from the last five years, to identify and centralize the most reliable and valid questionnaires created and used for the assessment of physical activity in children and adolescents.
CORRECTION OF LEARNING DISORDERS BY OPTIMIZING THE DEVELOPMENT OF SPATIAL AND TEMPORAL ORIENTATION
Authors: BĂLĂNEAN DENISA , BOTA EUGEN , PETRACOVSCHI SIMONA
Published: September 2021

Learning to read, write and calculate are proving to be some of the most significant cognitive processes in early education. The objective of this systematic review is to explore the associations between the psychomotor component and the academic achievement in writing, reading, and mathematics. An organized and methodical research of electronic databases was completed in order to determine significant studies. Twenty eligible articles were strictly evaluated, with extracted and summarized keywords. The two components of the psychomotor activity that influence reading were primarily the orientation ability and the fine motor skill, which is the one responsible for the correct spelling of “mirror-writing”. Differences in motor function were observed after intervention programmes. The results of all researchers have shown that there is a link between dysgraphia, dyslexia and the orientation ability or visual perception. Meanwhile, the role of cognitive and motor skills that underpinned mathematical performance was highlighted, and children who had a high capacity for spatial and visual orientation benefited from a better understanding and perception of geometric figures. However, the importance of students'''' spatial reasoning in relation to mathematics was identified, but only in terms of geometry. Poor quality of spatial notions has been found to be one of the causes of delay in the acquisition of reading, writing and mathematical calculation. The role of fine motor skills in the writing process was also noted, being of real importance in times when the child manipulates the writing tool and puts a word or a sentence on the page.

Published: September 2021

ABSTRACT: Introduction The concept of free time has evolved over the centuries according to various socially organized models. Thus, it was found that mankind has always enjoyed a certain type of leisure organization, various forms and activities of organization. Objective The study aims to identify a concept of physical education for free time, stimulating the desire to exercise, developing the spirit of initiative, ensuring continuity in the practice of motor activities. Methods Major benefits of web-based questionnaires and surveys are that they do not require the administration of materials in person, are accessible world-wide, and are therefore available cross-culturally. Results A majority of the subjects (68.5%) view a healthy diet as “very important” for a sport point of view. If we were to couple this with the “important” answer to this question we would find that a vast majority (94.4%) view diet and nutrition as a key component of physical activity. Conclusions Leisure physical activity helps for a healthy lifestyle, regardless of the profession you practice. Through this paper we intend to create a guide in the practice of physical leisure activities and to help in their practice. Nevertheless, many different types of exercise have been shown to be beneficial, including aerobic training, resistance or strength training, walking, hopping, swimming, aquatic exercise, as well as exercises to improve flexibility and balance for a healthy lifestyle.
Gender-specific association of risk factors in patients who underwent catheter ablation of atrial fibrillation
Authors: Troisi Federica , Guida Pietro , Di Monaco Antonio , Quadrini Federico , Vitulano Nicola , Grimaldi Massimo
Published: September 2021

Aims

Atrial fibrillation (AF) has been highlighted as a growing epidemic. Evidence is lacking on the role of different risk factors within both genders especially in AF patients referred for catheter ablation (CA). The objective was the evaluation of differences between men and women in the associations with aging, obesity and hypertension as the most highly contributing factors to AF onset and progression.

Methods

Cases selected among patients scheduled for CA as a rhythm-control strategy and controls from a recent Italian national survey on the population's health conditions were analysed to quantify the strength of association and to assess the existence of gender differences. To reduce the effect of possible confounding factors, both cases and controls were selected without preexisting comorbidities other than hypertension.

Results

At multivariate logistic regression analysis, cases (534 patients, 166 women) were significantly associated with the male sex, higher age, presence of obesity and hypertension in comparison to controls (17,983 subjects, 9,409 women). At analyses gender-stratified, age and obesity had a significant greater association in women than men. On the contrary, hypertension was relatively more frequent in men than women.

Conclusion

Although mechanisms linking risk factors and AF are complex, this study suggests the existence of differences mediated by gender in AF drug-refractory patients who underwent CA. A tailored public health programme to reduce the growing burden of AF needs to be designed to prevent and counter the increasing epidemic of the most common cardiac arrhythmia as well as its progression in more resistant forms.
Effect of graded dietary inclusion levels of hybrid rye grain on productive performance, the cost-effectiveness of nutrition and egg quality in laying hens
Authors: Mikulski Dariusz , Naczmański Jakub , Mikulska Marzena , Jankowski Jan
Published: September 2021

The study was designed to investigate productivity parameters, egg quality and the cost effectiveness of feeding laying hens with diets where ground wheat was replaced with varying levels of whole hybrid rye grain cv. Brasetto. A total of 396 Hy-Line Brown hens at 34 weeks of age were allocated to three treatment groups with 66 replicates (cages) of two hens each, and were fed isocaloric and isonitrogenous pelleted diets for 12 weeks. The diet for control group hens (R0) did not contain rye grain. In diets for hens from groups R100 and R200, ground wheat grain was partially replaced with whole rye grain at 100 g/kg and 200 g/kg, respectively. Whole intact rye grains were included in the diets. The cost of diets containing 10% and 20% of whole rye grain was by approximately 1.0% and 1.9% lower, respectively, compared with the control diet that contained no rye grain. During the entire 12-week feeding period, dietary treatments had no effect on laying rate (95.64% to 97.07%), egg weight (62.51 g to 62.74 g) or egg mass output (5.04 kg to 5.12 kg per hen). The inclusion of whole rye grain in layer diets caused a linear increase in feed intake (P<0.047) and tended to linearly increase the feed conversion ratio (FCR, P = 0.078). Both groups of hens fed diets containing whole rye grain were characterized by a linear decrease in the dry matter (DM) content of excreta (P = 0.001). Increased excreta moisture was accompanied by a tendency towards a higher incidence of dirty eggshells in R200 hens (P = 0.068). The inclusion of 100 g/kg of whole rye grain in layer diets decreased the cost of feed per kg of eggs by 1.9%. Dietary treatments had no significant effect on eggshell thickness (0.330 mm–0.345 mm), albumen quality (Haugh units, 83.46–85.84) or yolk color (3.8–4.0). The results of this experiment indicate that pre-pellet inclusion of whole rye (at up to 200 g/kg) in diets with supplemental NSP-degrading enzymes and phytase can be an effective and economically viable alternative to ground wheat in pelleted layer diets.

Published: September 2021

The aim of this paper is to investigate the determinants of the movement of non-performing loans in the banking sector of Bosnia and Herzegovina, as well as the impact of the COVID-19 pandemic on them. For this purpose, secondary data from the banking sector of BiH were used, over which a multi-regression analysis was performed. The variables non-performing loans, GDP, loan loss provision, and dummy variable COVID-19 were used in the analysis. The results of the analysis showed a significant influence of all three mentioned variables. The existence of a significant positive link between non-performing loans and the state of the country's economy has been proven. In addition to the above, it has been proven that the variable COVID-19 has a delayed effect on NPLs, due to the current application of the moratorium on loans.

يعتبر نظام المراقبة الإلكترونية بالدرجة الأولى من الأنظمة البديلة للعقوبة السالبة للحرية، إذ إن معظم التشريعات التي أخذت بهذا النظام، قصرته على المحكوم عليهم لتجنبهم الآثار السيئة الناتجة عن إيداعهم داخل السجون؛و المراقبة الالكترونية هي أحد البدائل الرضائية للعقوبات السالبة للحرية ،التي بمقتضاها يتم متابعة الشخص الخاضع لها إلكترونيا وعن بعد، من قبل أجهزة مخولة قانونا ، إذ يقضي العقوبة النافدة خارج السجن ،من خلال إخضاعه لمجموعة من الالتزامات ،و ضرورة توافر شروط محددة، و يترتب على مخالفة هذه الالتزامات،معاقبته بعقوبة سالبة للحرية. وقد جعله المشرع الجزائري من الأساليب العقابية البديلة عن العقوبة النافدة داخل المؤسسات العقابية، وبالرغم من محاسن السوار الالكتروني ، إلا أن هناك مساوئ تنتج عن استخدامه.

Published: September 2021

Background: Caregiver values and preferences with regard to oral immunotherapy (OIT) for treatment of food allergies are not widely reported. Understanding caregiver perspectives is integral to establishing shared decision-making in the treatment of food allergy.
Objective: We aimed to understand caregiver opinions that may influence caregivers in their decisions about OIT through social media. Methods: We searched a popular parenting web site for posts related to OIT from December 2008 to September 2019. We applied a
Preferred Reporting Items for Systematic Reviews and Meta-Analyses framework to review posts for inclusion, performed thematic content analysis to determine common themes, and calculated frequencies for each theme and subtheme. Posts and comments were included if they contained discussions
about OIT for immunoglobulin E‐mediated food allergy and were excluded if they were duplicates, comments from an original post from the original user, or comments on a nonrelevant original post. Results: Of 1300 posts and comments retrieved, 174 were included (13%).
Most were excluded because they did not directly address OIT for food allergy. Relevant posts could fall into multiple themes and were categorized under three main themes: attitudes (n = 128, “I am scared to do OIT but scared not to!”), logistics (n = 168, “We
will be doing this once LO [little one] is a little older”), and questions (n = 32, “How does it work?”). Conclusion: Caregivers communicate with each other through social media, expressing attitudes, logistics, and questions about OIT. Understanding
these lay perspectives may help guide clinicians in counseling and engage caregivers in decision-making.

This study aims to analyze the influence of Authentic Leadership and Strategic Management Skills on Organizational Performance mediated by Knowledge Management at the Indonesia Armed Force (TNI) Academy. This study tested seven hypotheses with structural equation modeling using the LISREL Ver.8.7 application. The sample of this research is 304 personnel of the TNI Academy.The results of this study found six hypotheses were accepted and one hypothesis was rejected. The rejected hypothesis was the direct influence of Strategic Management Skills on Organizational Performance. While the hypothesis of the indirect effect of Strategic Management Skills on Organizational Performance through Knowledge Management is acceptable. This means that Knowledge Management is an intervening variable that is very important for the implementation of increasing Strategic Management Skills. The results of this study encourage policy and managerial decision-makers within the TNI Academy to implement Knowledge Management optimally to maximize the impact on Organizational Performance from policy implementation and managerial decisions to improve Authentic Leadership and Strategic Management Skills. The novelty of this study is that Strategic Management Skills do not have a significant effect on Organizational Performance at the TNI Academy, giving different results from the theory in general. This can be overcome by implementing Knowledge Management properly in the TNI Academy.

Conversion to Reverse Total Shoulder Arthroplasty with and without Humeral Stem Retention: Mid-to Long-Term Results
Authors: Loucas Marios , Loucas Rafael , Kriechling Philipp , Bouaicha Samy , Wieser Karl
Published: September 2021

Background: Over the past decade, conversion to Reverse Total Shoulder Arthroplasty (RTSA) has become the preferred treatment for revision of an Anatomic Hemi (HA) or Total Shoulder Arthroplasty (TSA). However, conversion of failed stemmed shoulder arthroplasty to RTSA is still a highly demanding procedure and carries unique technical challenges and risks. Questions/Purposes: This study aimed to analyze the mid- to long-term results after conversion of failed anatomical shoulder arthroplasty to RTSA and investigate whether preserving the humeral stem offers advantages over revising the humeral stem. Materials and Methods: Between 2005 and 2018, 99 hemiarthroplasties and 62 total shoulder arthroplasties (total =161 shoulders; 157 patients) were revised to RTSA without (n=47) or with (n=114) stem exchange. Complications and revisions were documented from medical and surgical records. Longitudinal pre- and post-operative clinical (Constant-Murley (CS) score, Subjective Shoulder Value (SSV)), and radiographic outcomes were assessed. Complete clinical and radiographic follow-up was available on 80% of shoulders (127 patients; 128 of 161 procedures, 46 without and 82 with stem exchange) at a minimum of 24 months and a mean of 70 months (range, 24 to 184 months). Results: Humeral stem retention was associated with a significantly reduced surgical time (193 min vs. 227 min, p=0.001, less blood loss (591 mL vs. 753 mL, p=0.037), less intraoperative complications (13% vs. 19%; Odds Ratio (OR), 1.4, p=0.32) and fewer subsequent reinterventions (19% vs. 28%; OR, 2.3, p=0.06). The complication/revision rate leading to drop out from the study was considerable in the stem revision group (ten patients; ten of 114 shoulders (9%)), but there were no complication-related dropouts in the stem-retaining group. Conclusion: Our findings suggest that humeral stem revision is associated with decreased surgical time, less blood loss, less intra- and postoperative complications, and a lower revision rate compared to humeral stem retention. Based on these findings, a shoulder arthroplasty system modularity offers substantial benefit if conversion to reverse total shoulder arthroplasty becomes necessary. Level of Evidence: Level III, therapeutic study.

Background:

Spinal dural arteriovenous fistula (SDAVF) is the most frequent vascular malformation of the spine and accounts for approximately 70% of all vascular spinal malformations. In rare cases, SDAVF rupture and subsequent subarachnoid hemorrhage or intramedullary hematoma may occur. The aim of this article is to present a fatal case of SDAVF rupture after a Rathke’s cleft cyst (RCC) endoscopic resection.

Case Description:

An 80-year-old female was referred to our hospital with a clinical presentation of bilateral reduction in visual acuity, bitemporal hemianopsia, and sellar magnetic resonance imaging (MRI) highly suggestive of RCC. After the first endonasal endoscopic surgery, the cyst was partially removed and vision improved. No signs of cerebrospinal fluid (CSF) leak were observed. After 1 year, the patient returned because of RCC recurrence and decreased visual acuity. In the second procedure, the lesion was totally resected and CSF leak was observed. A nasoseptal flap was rotated to cover the skull base defect. The patient developed subtle paraparesis followed by paraplegia on the 4th postoperative day. The dorsal spine MRI revealed a T3-T4 intramedullary hematoma. A dorsal laminectomy was performed and a SDAVF was observed. During microsurgery, at the right T3 nerve root level, an arteriovenous shunting point was identified, coagulated, and divided. The intramedullary hematoma was evacuated. The patient developed neurogenic and septic shock and died.

Conclusion:

Venous hypertension, venous wall fragility, and venous thrombosis seem to be the main factors involved in SDAVF rupture. In this particular case, reduction of the extravascular pressure and sudden variation in the pressure gradient caused by sustained CSF leak, also appeared to play an important role in SDAVF rupture. It may represent one more complication related to radical resection of RCC.
The need for neuroimaging in first manifestations of psychiatric symptoms
Authors: Saleh Christian , Seidl Ulrich , Hutter Gregor , Hund-Georgiadis Margret
Published: September 2021

Background:

Brain imaging in psychiatry, especially by first-episode psychiatric symptoms, is unfortunately not a standard procedure in psychiatric clinics and is recommended only if indicated by history or if associated with neurological findings. As a result, the most serious diagnoses can be delayed or missed.

Case Description:

We describe a patient who presented with psychiatric symptoms admitted initially to a psychiatric clinic. Thanks to routine imaging the diagnosis of a brain tumor could be made with prompt transfer to neurosurgery.

Conclusion:

Brain imaging should be a mandatory procedure upon admission to a psychiatric clinic also in patients who present with exclusive psychiatric symptoms.
VERIFICATION OF THE PARETO PRINCIPLE FOR INCOME FROM SCIENTIFIC ACTIVITY OF HIGHER EDUCATION INSTITUTIONS OF UKRAINE
Authors: Slav’yuk Rostyslav , Totska Olesia
Published: September 2021

The purpose of the article is to verify the Pareto principle in terms of revenues to the special fund of higher education institutions of Ukraine based on the results of scientific and scientific-technical work on international cooperation projects, scientific and scientific-technical work under economic agreements and scientific services. With the help of ABC-analysis of indicators of income from scientific activity, domestic higher education institutions are divided into three groups: A – higher education institutions with a large amount of income from scientific activities; B – higher education institutions with an average level of commercialization of scientific activity; C – higher education institutions with little or no income from research. It was obtained that group A included 29 (19,595 %) higher education institutions of Ukraine, which in 2016–2018 provided paid scientific services in the amount of UAH 739,747 million (79,39 % of the total). Group B was formed by 34 (22,973 %) domestic higher education institutions, whose scientific activity in the analyzed period brought income in the amount of UAH 147,954 million (15,88 % of the total). Group C included 85 (57,432 %) Ukrainian higher education institutions, which earned UAH 44,082 million (4,73 % of the total) as a result of their scientific work. It was found that the Pareto principle 20/80 was reflected in the activities of higher education institutions in Ukraine. Strategies for commercialization of research results for domestic higher education institutions from each group are proposed: group A – leader’s strategy; group B – the applicant’s strategy; group C – strategy of the beginner.
CORPORATIONS' OWNERSHIP CONCENTRATION: THEORETICAL ASPECT
Authors: Rudenok Olha
Published: September 2021

Corporate governance and its mechanisms, including ownership structure, have a long history of research. Many scientific papers show that when the ownership concentration grows above a certain limit, it not only directly affects the performance of firms and their value but also indirectly affects the mechanism of corporate governance. In the case of the concentration of ownership, majority shareholders can gain significant control over the firm to obtain private benefits from minority shareholders. In such circumstances, special attention should be paid to the concentration of ownership and its relationship with the activities of the firm and its value. The article highlights the essence of the concept of "ownership concentration" from the standpoint of corporate governance and from the standpoint of the characteristic of the corporations' capital structure. The peculiarities of corporate governance in Ukraine and in the world are generalized with their division into internal and external mechanisms. The concentration of ownership as a tool of corporate governance is determined since the fact that there are shareholders with significant stakes that have the necessary incentives and resources to monitor and discipline management. It is noted that the ownership concentration can be considered as a tool to compensate for the shortcomings (ineffectiveness) of external mechanisms of corporate governance. As a quantitative indicator of capital structure, the ownership concentration is measured by the number of shareholders and the percentage of their individual or collective ownership of shares, considering exercising control influence on the joint-stock company. The threshold of concentrated ownership is indicated, based on Ukrainian legislation and existing approaches.
