Authors: Grostern Jessica , Lajoie Yves , Paquet Nicole
Published: February 2021

Purpose: The Fukuda stepping test assesses spatial orientation in people with vestibular disorders. To standardize the test, it is important to know which factors influence the outcome. This study investigated the impact of two factors, a concurrent cognitive task and step height, on the Fukuda stepping test in healthy individuals. Method: A total of 16 young adults participated and completed 20 trials of the 50-step Fukuda stepping test in four conditions: comfortable and high step height and with and without a cognitive task. Body kinematics were collected using the three-dimensional motion analysis Vicon system. The cognitive task was to listen to a sequence of three-digit numbers and identify the total number of times that one pre-determined digit was presented. Results: All participants slowly turned and drifted forward during the test. The concurrent cognitive task yielded significantly shorter forward displacement and lateral deviation and lower stepping height, and high stepping produced significantly greater body rotation and lateral deviation. Conclusions: Performance on the Fukuda stepping test in healthy young individuals is influenced by a concurrent cognitive task and by step height. Clinicians and researchers must instruct people to use a comfortable step height during the test, and they must be aware that a concurrent cognitive task may improve test performance, at least among young adults.

Published: February 2021

The article covers the issue of playing activities in basketball. The value of speed and accuracy of basketball players' game actions is revealed. The dependence of basketball players' game efficiency on indicators of their psychophysical development of their organism and the need to study the influence of morphofunctional and psychophysiological indicators of basketball players on the speed and accuracy of game actions are substantiated.

In sports games, technical training is of great importance, which includes a large number of different techniques. Basketball activity is based on individual and group technical actions of athletes, the main of which are throws to the basket, passes, driving, interception, selection, selection of the ball, etc. The ability to perform these actions quickly and accurately is the main condition for a successful game of basketball players.

Game efficiency depends on the spatio-temporal characteristics of game actions, which, in turn, are determined by the peculiarities of the psychophysical development of the body of athletes.

One of the main ways to achieve high sportsmanship is the constant improvement of the technique of the chosen sport, the study of its structure, components and psychophysiological basis.

Therefore, the study of the parameters of the game activities of students who play basketball, which includes analysis of the impact of morphofunctional and psychophysiological indicators of the body on competitive efficiency, is relevant in today's conditions of intensification of sports training.

Research and development of means for effective prevention and treatment of diseases in animals are one of the priorities for modern veterinary science. Means based on the transfer factor are quite promising to solve these problems. One of the stages of obtaining a qualitative transfer factor specific to a particular disease is the sensitization of the body of donor animals. The purpose of this work was to investigate the blood biochemical parameters of donor cows after sensitization according to different schemes. The experiments were performed on cows of the Ukrainian black-spotted dairy breed, aged 4–5 years. Sensitization of pregnant cows was performed 1–1.5 months before calving with a concentrated formol-alum vaccine against salmonellosis of calves manufactured by the Kherson Biofactory. The vaccine was administered to the animals of the first experimental group one month before calving, one-time in a dose of 10 ml. Animals of the second experimental group 1.5 months before calving were two-time vaccine administered with an interval between injections of 10 days in doses of 10 and 15 ml. Studies have shown that in donor cows, which were two-time vaccine administered, there was an increase in hemoglobin content by 13% (P<0.05). There was also a decrease in glucose and creatinine content by 13–28% (P<0.05–0.01) in the blood serum of pregnant cows, which did not depend on the sensitization scheme, and a tendency to a decrease in total protein content. Regardless of the sensitization scheme of cows, an increase in serum aminotransferase activity was observed by 1.3–1.5 times (P<0.05–0.001), and if alanine aminotransferase activity increased mainly with a single injection of the vaccine, then aspartate aminotransferase activity was more intensively increased after a two-time vaccine administration. There was a slight decrease in сalcium (by 5–9%) and phosphorus (by 2–3%) content and an increase in potassium content (by 2–5%) in the blood serum of pregnant cows two weeks after vaccine administration regardless of the sensitization scheme.

Ukraine in Modern Globalization Processes: Challenges to the National State
Authors: Novoskoltseva Liudmyla
Published: February 2021

In the 20th and 21st centuries, the world has faced the acceleration of transnationalization, the strengthening of interdependence and the establishment of an international order with the help of the UN and other international organizations, as well as the phenomenon of “erosion” of state sovereignty. The information revolution and the interaction of cultures and values have intensified the trend towards building a democratic society and fighting for human rights and freedoms. The globalization undermines an ability of the state to maintain borders and exercise sovereignty. States today can be legally sovereign, but in practice they are forced to negotiate with all the actors on the world stage, as a result of which their freedom of action is significantly limited. The development of the modern world is characterized by the processes of globalization, enhances the universalization of all spheres of social life and certainly cannot but influence the functioning of national states. Globalization forces us to revise the traditional principles of sovereignty in connection with changes in ideas about the difference between internal and external, state and international, territorial and non-territorial politics. Ukraine's accession of independence provides for the formation of the integral socio-political, self-identified community, capable of withstanding internal and external challenges. In Ukraine, the process of becoming the full-fledged nation-state with its own interests continues. This problem is also actualized by the ambitious goal that has been set, about Ukraine's entry into forty developed countries of the world.

Image recognition is used to retrieve, analyse, understand, and process images from the real world to convert them into digital information. In this area involved data mining, machine learning, pattern recognition, knowledge extension. Developments in the image recognition area have resulted in computers and smartphones becoming capable of mimicking human eyesight. Improved cameras in modern devices can take pictures of very high quality, and with the help of new software, they receive the necessary information and on the basis of the received data is processed images. However, food recognition challenges modern computer vision systems and needs to go beyond just an visible image. Compared to understanding the natural image, visual prediction of ingredients requires high-level solutions and previous knowledge. This creates additional problems, because food components have high variability between the class, when cooking, you have to convert components and the ingredients are often included in the cooked dish. The recognition system allows you to take a step toward understanding the food supply systems such as calorie score and create recipes. The recognition system can be used to address wider problems, such as the prediction of the image on the consistency of the folding elements.

Solar energy is widely used in cases where the inaccessibility of other energy sources in combination with a sufficient amount of solar radiation justifies it economically. With the help of a system of solar collectors, you can significantly reduce energy costs for hot water supply and heating. In addition, the use of this system helps reduce CO2 emissions. The potential of solar energy in Ukraine is quite high. According to the climatic conditions of our region, solar activity is slightly lower than in the southern regions, so the use of flat solar collectors, which use both direct and scattered solar radiation, is effective for our region. The use of heat collectors in the home for water supply and heating of small areas is economically feasible, as it does not require significant costs. Heat supply plants using non-traditional energy sources are promising in terms of fuel savings and reduction of harmful effects on the environment. To increase the service life, economical use of heat and fuel, efficient operation of the installation requires the use of automation. The article considers the development of a mathematical model of a heat supply installation based on a solar collector. For automated control of the heat supply installation, it is necessary to know the properties of this installation as a whole and its individual elements. For this purpose, models of individual elements of the heat supply installation in a linear approximation are considered. The solar collector is conditionally divided into two parts. The model of the ground heat exchanger is developed. Also e battery models and consumer premises. The given matrices of elements of installation of heat supply are united in the uniform system of matrices. The obtained results allow estimating in advance efficiency of their use and economic attractiveness.

A study on the immediate effects of neuromuscular electrical stimulation on the corticospinal tract excitability of the infraspinatus muscle
Authors: Endo Naoto , Ishii Daisuke , Ishibashi Kiyoshige , Yamamoto Satoshi , Takeda Kotaro , Kohno Yutaka
Published: February 2021

BACKGROUND: Rotator cuff muscles are structurally and functionally different from other upper-limb muscles because they are responsible for glenohumeral joint stability. Neuromuscular electrical stimulation (NMES) induces excitability changes (increase or decrease) of the corticospinal tract (CST) in the peripheral muscles, such as those of the finger. However, it remains unclear whether similar results are obtained when targeting the infraspinatus muscle, which has properties that differ from other muscles, in healthy subjects. OBJECTIVE: We investigated the immediate effects of NMES on the corticospinal excitability of the infraspinatus muscle, a rotator cuff muscle, in healthy subjects. METHODS: Thirteen healthy right-handed men (mean age: 26.77 ± 2.08 years) participated in this study. The motor evoked potentials (MEPs) and the maximum compound muscle action potential (Mmax) were recorded before NMES to the right infraspinatus and within 15 minutes after the end of the NMES. RESULTS: NMES on the infraspinatus muscle significantly increased its MEP amplitude (Pre: 0.45 mV [0.33–0.48]; Post: 0.54 mV [0.46–0.60] (median [lower quartile to higher quartile]); p= 0.005) but had no effect on Mmax (Pre: 2.95 mV [2.59–4.71]; Post: 3.35 mV [2.76–4.72]; p= 0.753). CONCLUSIONS: NMES application to the infraspinatus muscle increases CST excitability without producing immediate changes in the neuromuscular junction or muscle hypertrophy.

Background: Psychological difficulties such as anxiety, depression, and irritability are common in Huntington’s disease, even for premanifest individuals. However, very little evidence exists of psychological approaches to manage this distress. We have conducted a feasibility study with an embedded qualitative component to investigate the possibility of using mindfulness-based cognitive therapy (MBCT) and present here the findings from the qualitative data. Objective: To investigate the experience of premanifest individuals learning and practising mindfulness through completing a course of MBCT. Methods: Twelve premanifest individuals completed a course of MBCT and attended three follow up reunion meetings over the following year. Eleven participants agreed to be interviewed post-course and ten participants one year post-course about their experience of the course and any impact on their lives. Seven participants nominated a friend or relative (supporter) to be involved in the research, of whom six agreed to be interviewed post-course and two at one year about the impact of the course on the participants. Data were analysed using reflexive thematic analysis. Results: Four themes were constructed from the data: 1) A meeting of minds: the group facilitating learning and support; 2) Mindfulness is hard, but enables more effective emotional management; 3) Mindfulness can change the relationship with self and others; and 4) Benefiting from mindfulness: the importance of persistence. Conclusion: The participants who completed the course found it beneficial. Some participants reported reductions in psychological distress, a greater sense of calm and better emotion regulation, with some of these positive changes also noticed by supporters. MBCT is worthy of further investigation for this population.

Dynamic monitoring feedback iteration control for damping-adjustable semi-active suspension systems
Authors: Li Chongchong , Xiong Jiangyong , Liu Tingshan , Zhang Ziang
Published: February 2021

In order to further improve vehicle ride performance, a dynamic monitoring feedback iteration control algorithm is proposed by combining the features of a variable-damping semi-active suspension system and applying them to the system. A seven-degree-of-freedom finished vehicle simulation model is built based on MATLAB/Simulink. The root-mean-square values of the acceleration of the sprung mass, the dynamic travel of the suspension and the dynamic tire load are taken as evaluation indicators of vehicle ride performance. An analytic hierarchy process (AHP) is used to determine the weighting coefficients of the evaluation indicators, and a genetic algorithm is utilized to determine the optimal damping of the suspension under various typical working conditions. Suspension damping is controlled with a dynamic monitoring feedback iteration algorithm. The correction coefficients of the control algorithm are determined according to the deviation between the obtained damping and the optimized damping so that the control parameters will agree with the optimal result under typical working conditions, and the control effect under other working conditions is verified. The simulation results indicate that the proposed dynamic monitoring feedback iteration control algorithm can effectively reduce the root-mean-square value of the acceleration of the sprung mass by 10.56% and the root-mean-square value of the acceleration of the dynamic travel of the suspension by 11.98% under mixed working conditions, thus improving vehicle ride performance. The study in this paper provides a new attempt for damping control of semi-active suspension and lays a theoretical foundation for its application in engineering.
A multi-shop integrated scheduling algorithm with fixed output constraint
Authors: Xia Yingchun , Xie Zhiqiang , Xin Yu , Zhang Xiaowei
Published: February 2021

The customized products such as electromechanical prototype products are a type of product with research and trial manufacturing characteristics. The BOM structures and processing parameters of the products vary greatly, making it difficult for a single shop to meet such a wide range of processing parameters. For the dynamic and fuzzy manufacturing characteristics of the products, not only the coordinated transport time of multiple shops but also the fact that the product has a designated output shop should be considered. In order to solve such Multi-shop Integrated Scheduling Problem with Fixed Output Constraint (MISP-FOC), a constraint programming model is developed to minimize the total tardiness, and then a Multi-shop Integrated Scheduling Algorithm (MISA) based on EGA (Enhanced Genetic Algorithm) and B&B (Branch and Bound) is proposed. MISA is a hybrid optimization method and consists of four parts. Firstly, to deal with the dynamic and fuzzy manufacturing characteristics, the dynamic production process is transformed into a series of time-continuous static scheduling problem according to the proposed dynamic rescheduling mechanism. Secondly, the pre-scheduling scheme is generated by the EGA at each event moment. Thirdly, the jobs in the pre-scheduling scheme are divided into three parts, namely, dispatched jobs, jobs to be dispatched, and jobs available for rescheduling, and at last, the B&B method is used to optimize the jobs available for rescheduling by utilizing the period when the dispatched jobs are in execution. Google OR-Tools is used to verify the proposed constraint programming model, and the experiment results show that the proposed algorithm is effective and feasible.

Published: February 2021

Impedance mismatching between different phases of a multiphase transformer is generally observed e.g., in a three-phase to seven-phase transformer, due to an unequal number of turns in different coils. This mismatching introduces error in the study of per phase equivalent circuit diagrams as well as induces an imbalance in output voltages and currents. Therefore, it is a challenging task to develop a per-phase equivalent circuit for the secondary and primary sides (In some cases) too. This paper proposes an artificial intelligence optimization technique like PSO based modeling of the per-phase equivalent circuit of the secondary side. This paper deals with the modeling and simulation of a three-phase to seven-phase power transformer using Artificial Intelligence technique like particle swarm optimization (PSO) and Genetic Algorithm (GA). The proposed model is optimized through PSO and GA algorithms and tested for minimum voltage error in each phase. The proposed model is designed and the objective function is optimized by PSO & GA in MATLAB environment. It is found that the optimized model can be effectively implemented as a per-phase equivalent circuit for the secondary side.

Compared with the traditional negative selection algorithms produce detectors randomly in whole state space, the boundary-fixed negative selection algorithm (FB-NSA) non-randomly produces a layer of detectors closely surrounding the self space. However, the false alarm rate of FB-NSA is higher than many anomaly detection methods. Its detection rate is very low when normal data close to the boundary of state space. This paper proposed an improved FB-NSA (IFB-NSA) to solve these problems. IFB-NSA enlarges the state space and adds auxiliary detectors in appropriate places to improve the detection rate, and uses variable-sized training samples to reduce the false alarm rate. We present experiments on synthetic datasets and the UCI Iris dataset to demonstrate the effectiveness of this approach. The results show that IFB-NSA outperforms FB-NSA and the other anomaly detection methods in most of the cases.
Research on the teaching quality evaluation of physical education with intuitionistic fuzzy TOPSIS method

Under the background of the national fitness craze, the demand space for social sports professionals is constantly expanding. However, according to the author’s investigation, the overall situation shows that the number of high-quality social sports professionals in Chinese colleges and universities is relatively small. Among them, the unsound teaching quality evaluation system of social sports major is one of the important reasons affecting the cultivation of high-quality talents, so it is imperative to construct a sound teaching quality evaluation system of social sports major. At the same time, the perfect social physical education teaching quality evaluation system is an important basis for teachers’ teaching job evaluation and strengthening teachers’ management. And it is frequently considered as a multi-attribute group decision-making (MAGDM) issue. Thus, a novel MAGDM method is needed to tackle it. Depending on the conventional TOPSIS method and intuitionistic fuzzy sets (IFSs), this essay designs a novel intuitive distance based IF-TOPSIS method for teaching quality evaluation of physical education. First of all, a related literature review is conducted. What’s more, some necessary theories related to IFSs are briefly reviewed. In addition, since subjective randomness frequently exists in determining criteria weights, the weights of criteria are decided objectively by utilizing CRITIC method. Afterwards, relying on novel distance measures between IFNs, the conventional TOPSIS method is extended to the intuitionistic fuzzy environment to calculate assessment score of each alternative. Eventually, an application about teaching quality evaluation of physical education and some comparative analysis have been given. The results think that the designed method is useful for teaching quality evaluation of physical education.

The existing recommender system provides personalized recommendation service for users in online shopping, entertainment, and other activities. In order to improve the probability of users accepting the system’s recommendation service, compared with the traditional recommender system, the interpretable recommender system will give the recommendation reasons and results at the same time. In this paper, an interpretable recommendation model based on XGBoost tree is proposed to obtain comprehensible and effective cross features from side information. The results are input into the embedded model based on attention mechanism to capture the invisible interaction among user IDs, item IDs and cross features. The captured interactions are used to predict the match score between the user and the recommended item. Cross-feature attention score is used to generate different recommendation reasons for different user-items.Experimental results show that the proposed algorithm can guarantee the quality of recommendation. The transparency and readability of the recommendation process has been improved by providing reference reasons. This method can help users better understand the recommendation behavior of the system and has certain enlightenment to help the recommender system become more personalized and intelligent.

With the rapid development of the environmental, meteorological and marine data management, fuzzy spatiotemporal data has received considerable attention. Even though some achievements in querying aspect have been made, there are still some unsolved problems. Semantic and structural heterogeneity may exist among different data sources, which will lead to incomplete results. In addition, there are ambiguous query intentions and conditions when the user queries the data. This paper proposes a fuzzy spatiotemporal data semantic model. Based on this model, the RDF local semantic models are converted into a RDF global semantic model after mapping relational data and XML data to RDF local semantic models. The existing methods mainly convert relational data to RDF Schema directly. But our approach converts relational data to XML Schema and then converts it to RDF, which utilizes the semi-structured feature of XML schema to solve the structural heterogeneity between different data sources. The integration process enables us to perform global queries against different data sources. In the proposed query algorithms, the query conditions inputted are converted into exact queries before the results are returned. Finally, this paper has carried out extensive experiments, calculated the recall, precision and F-Score of the experimental results, and compared with other state-of-the-art query methods. It shows the importance of the data integration method and the effectiveness of the query method proposed in this paper.

Published: February 2021

Background: The gastrointestinal tract is considered as a potential origin of Parkinson’s disease (PD) pathology. Besides constipation, appendectomy and inflammatory bowel disease have also been associated with a higher PD-risk, but findings have been inconsistent. To date, there is only one previous study suggesting that irritable bowel syndrome (IBS) is associated with an increased risk of PD. Objective: To evaluate whether IBS is associated with a higher risk of PD. Methods: In this retrospective registry-based cohort study, we identified 28,150 patients that were diagnosed with IBS (IBS+) during the years 1998–2014, using data from the Finnish Care Register for Health Care. In addition, 98,789 IBS-free reference subjects (IBS-) of same age and gender and living in the same municipality were included. The study subjects were followed until the end of the year 2014 to analyze the incidence of PD. The association between IBS and PD was assessed by a Cox proportional hazards model. Results: Diagnosis of IBS was associated with a higher hazard of PD with an adjusted hazard ratio (aHR) of 1.70 (95% CI 1.27–2.26). However, the ratio of hazard rates for PD between IBS+ and IBS- subjects was not constant over time. The Cox model with time-varying coefficient for IBS status showed that the hazard of PD was significantly higher in IBS patients only during the first two years of follow-up (aHR 2.96, 95% CI 1.78–4.92). Conclusion: Our findings indicate that the association between IBS and PD is likely explained by reverse causation and detection bias. It remains open whether IBS is an actual risk factor or a prodromal symptom of PD.
