Purpose: to establish links of cognitive functions from special training of qualified boxers. Material and methods. Preceding victorious methods have been used: analysis of scientific-methodical information and dzherel to the Internet; chronodynamometry; psychophysiological methods of education; methods of mathematical statistics. There were 26 qualified boxers in bulo, 18-24 years old. According to the index of creatine phosphate preceding of all boxers, there were two different groups. The first group with a high level of performance (from 200 and above conventional units) and a group with a low level of special performance (below 200 conventional units). Before the first group, 12 individuals were consumed, before the other – 14 athletes. Results: on the basis of the analysis of scientific-methodical information, the Internet connection and communication of the advanced practical information in the field of sports was established, and the structure of sports martial arts, and especially boxing, is characterized by the call of synchronization between the two sportsmen and the conversion For an effective reception of information, analysis and acceptance of the solution of a similar response to the supernatural, it is necessary to activate cognitive functions, such as: verbal and non-verbal intelligence and memory. A correlation analysis was carried out for the development of the peculiarities of the links in the special prasezdatnost and the cognitive characteristics. Conclusions. The results of a correlation analysis between special training and indicators of the cognitive test «Establishing Regularities» allowed for the emergence of reliable links among boxers because of the high level of precision of special performance indicators and efficiency. Boxers due to the decrease in the level of special praise rate help to achieve a reliable correlation without being an indicator of productivity. An analysis of the results in the field of special training and indicators of the cognitive test «Correspondence of numbers» has shown the prevalence of correlation in boxers due to the high level of special training. Boxers due to the decrease in the level of special performance help to promote the appearance of reliable links due to the indicators of efficiency, latency and stability. Carrying out a correlation analysis between special training and indicators of the cognitive test «Memory for words» has shown in the absence of one basic connection between special training and performance indicators among boxers due to low reduction. Boxers from the highest level of special prazdatnosty reliable correlation links in the tests are not possible. Keywords: boxing, cognitive functions, special performance, qualified athletes, correlation analysis.

The internet service is provided by a given number of servers located in the main node of internet service provider (ISP). In some cases; the overload problem was occurred because a demand on a given website goes to very high level. In this paper, a fuzzy logic control (FLC) has proposed to distribute the load into the internet servers by a smart and flexible manner. Three effected parameters are tacked into account as input for FLC: link capacity which has three linguistic variables with Gaussian membership function (MF): (small, medium and big), traffic density with linguistic variables (low, normal and high) and channel latency with linguistic variables (empty, half and full); with one output which is the share server status (single, simple and share). The proposed work has been simulated by using MATLAB 2016a, by building a structure in the Fuzzy toolbox. The results were fixed by two manners: the graphical curves and the numerical tables, the surface response was smoothly changed and translates the well-fixed control system. The numerical results of the control system satisfy the idea of the smart rout for the incoming traffics from the users to internet servers. So, the response of the proposed system for the share of server ratio is 0.122, when the input parameter in the smallest levels; and the ratio is 0.879 when the input parameters are in highest level. The smart work and flexible use for the FLC is the main success solution for most of today systems control.

Cardiac surgical procedures assisted by cardiopulmonary bypass (CPB) impair cognitive functions. Several studies, however, showed that cognitive functions were unaffected in patients undergoing either primary coronary artery bypass grafting (CABG) or more complex surgery assisted by CPB. Therefore, we conducted a straightforward study to compare patient groups who differed significantly in terms of risk factors such as prolonged CPB times. Consecutive patients (n = 54) were included, undergoing either non-primary CABG, e.g. valve and/or CABG, (n = 30) or primary CABG (n = 24), assisted by CPB. Cognitive function was determined pre-operatively on the day of hospital admission, and post-operatively after one and six months using the Cognitive Drug Research computerized assessment battery. Data from the fourteen individual task variables were summarized in four composite scores: Power of Attention (PoA), Continuity of Attention (CoA), Quality of Episodic Memory (QoEM), and Speed of Memory (SoM). In the non-primary CABG patients, both CoA and QoEM improved after 1 month (p = 0.001 and p = 0.016, respectively), whereas, after 6 months, CoA (p = 0.002), QoEM (p = 0.002) and SoM (p < 0.001) were improved. In primary CABG patients, CoA improved at one month after surgery (p = 0.002) and, after six months, not only CoA (p = 0.003), but also QoEM and SoM were improved (p = 0.001 and p = 0.030, respectively). The test performance was similar in non-primary and primary CABG patients after surgery. Our present study shows a post-operative improvement of cognitive composite scores after cardiac surgery assisted by CPB in both non-primary CABG and in primary CABG patients.

In the Internet of Things era, users are willing to personalize the joint behavior of their connected entities, i.e., smart devices and online service, by means of trigger-action rules such as “IF the entrance Nest security camera detects a movement, THEN blink the Philips Hue lamp in the kitchen.” Unfortunately, the spread of new supported technologies makes the number of possible combinations between triggers and actions continuously growing, thus motivating the need of assisting users in discovering new rules and functionality, e.g., through recommendation techniques. To this end, we present , a semantic Conversational Search and Recommendation (CSR) system able to suggest pertinent IF-THEN rules that can be easily deployed in different contexts starting from an abstract user’s need. By exploiting a conversational agent, the user can communicate her current personalization intention by specifying a set of functionality at a high level, e.g., to decrease the temperature of a room when she left it. Stemming from this input, implements a semantic recommendation process that takes into account ( a ) the current user’s intention , ( b ) the connected entities owned by the user, and ( c ) the user’s long-term preferences revealed by her profile. If not satisfied with the suggestions, then the user can converse with the system to provide further feedback, i.e., a short-term preference , thus allowing to provide refined recommendations that better align with the original intention. We evaluate by running different offline experiments with simulated users and real-world data. First, we test the recommendation process in different configurations, and we show that recommendation accuracy and similarity with target items increase as the interaction between the algorithm and the user proceeds. Then, we compare with other similar baseline recommender systems. Results are promising and demonstrate the effectiveness of in recommending IF-THEN rules that satisfy the current personalization intention of the user.

The research objective was to study the relationships of players’ efficiency in attack and block with their anthropometric characteristics. Data on men’s weight and height and their proficiency in the game were used. The subjects were the members of the Estonian, Italian, French and Croatian national volleyball teams who participated in Pool B of the European Championship. Data are given on men’s height, weight, age, total number of spikes, attack errors, attacks won, efficiency of attack, total number of blocks, block errors, blocks won, and efficiency of block. In addition, the number of points won by men and their positions in the game are given. Minimums, maximums, standard deviations and means were calculated. To find correlations, Pearson’s correlation analysis (p<0.05) was used. In our study, taller and heavier players proved to be more efficient at attack. Comparison of positions showed that middle blockers were taller and performed more blocks, setters were shorter and performed the least of attacks, and outside attackers and opposite attackers were of medium height and carried the greatest load of attack. As a conclusion, it was found that, in professional volleyball, height correlated with the efficiency of attack (r= 0.534; p<0.05), and weight also correlated with the efficiency of attack (r= 0.518; p<0.05). There was no correlation between the anthropometric characteristics and block in volleyball at the professional level in our study. In volleyball, the greatest load at attack is carried by outside attackers and opposite attackers, while middle blockers have the greatest load at block. Setters perform the smallest number of attacks.

Purpose This paper reviews the latest management developments across the globe and pinpoints practical implications from cutting-edge research and case studies. Design/methodology/approach This briefing is prepared by an independent writer who adds their own impartial comments and places the articles in context. Findings If you search images of the word “strategy” on the internet, three of the first seven images to appear on Google (other search engines are available) include chess pieces, while two of the top ten hits involve light bulbs. Aside from the obvious conclusions that any strategic discussion should either involve chess grand masters or well-lit rooms, it is clear that most people assume winning games with lots of moves are possible is the key to a successful strategy. But is this a valid analogy, even at a high level? Originality/value The briefing saves busy executives and researchers hours of reading time by selecting only the very best, most pertinent information and presenting it in a condensed and easy-to-digest format.

This paper reports on the first stage of a study on the usage of electronic information services (EIS) by staff and students at Glasgow Caledonian University (GCU) and Leeds Metropolitan University (LMU). The study used by qualitative and quantitative methodologies. The questionnaires used at GCU were modeled on those developed at LMU. The project aimed to monitor off-campus usage of EIS, the use of passworded databases, and the freely available internet. The volume of electronic citations in students' course work and the possibility of developing routine performance indicators were also examined. Focus Groups were conducted with both staff and students between November 2001 and March 2002. These suggested, inter alia, that paramedics are the heaviest users of EIS and that paramedicine is the subject area where EIS are most integrated into the curriculum. Attitudes to the internet are extremely varied. Mode of attendance and workplace usage are important factors.

Introduction. Modern curriculum («Physical culture 10-11 classes») for the last decades is developed according to requirements of operating standards of basic and full general secondary education. In particular on a modular system Aim is to find out the changes of technical preparedness of high school students according to the results of implementation the variable module "Wrestling". Material and methods. There were used theoretical analysis and generalization of scientific and methodical data and sources of the Internet, analysis of documentary materials, pedagogical testing, pedagogical experiment (there was tested the effectiveness of the developed variable module "Wrestling" in the physical education of high school students in secondary schools), methods of mathematical statistics. During the 2017-2019, school years were involved 53 students of 10 classes (31 boys and 22 girls) and 74 students of 11 classes (41 boys and 33 girls). Results. Analysis of the 10th grade boys’ results indicated the presence of significant changes a high level (p≤0.01). In all cases, the average scores improved by 0.54-0.71 points (from 16.79% to 22.66% of initial level). The girls of the 10th grade best realized the technical and tactical elements standing - dumping, beating (24.76% improvement from the initial level) and on the ground - twists and somersault (24.51%, respectively). For 11th grade boys technical and tactical improvement there was on the level of p≤0.05(9.35–18.45% of the initial level). According to the percentage values for 11th grade girls, in general, there were changes in grades by 10.67–21.13% from the initial level. Conclusions. It was found that in most technical and tactical elements, girls show higher relative rates of improvement. The only exception is in somersault with running, where the boys had the best changes. The factors of this are the better functional start an organism of young people at the beginning of the pedagogical experiment and higher indicators of fitness, which all owed to better master the technique of the wrestling elements at the beginning of the variable module. The girls gradually increased both fitness and technique of performing theses pacificelements of wrestling.

Thanks to patients Phineas Gage and Henry Molaison, we have long known that behavioral control depends on the frontal lobes, whereas declarative memory depends on the medial temporal lobes. For decades, cognitive functions – behavioral control, declarative memory – have served as labels for characterizing the division of labor in cortex. This approach has made enormous contributions to understanding how the brain enables the mind, providing a systems-level explanation of brain function that constrains lower-level investigations of neural mechanism. Today, the approach has evolved such that functional labels are often applied to brain networks rather than focal brain regions. Furthermore, the labels have diversified to include both broadly-defined cognitive functions (declarative memory, visual perception) and more circumscribed mental processes (recollection, familiarity, priming). We ask whether a process – a high-level mental phenomenon corresponding to an introspectively-identifiable cognitive event – is the most productive label for dissecting memory. For example, the process of recollection conflates a neurocomputational operation (pattern completion-based retrieval) with a class of representational content (associative, high-dimensional, episodic-like memories). Because a full theory of memory must identify operations and representations separately, and specify how they interact, we argue that processes like recollection constitute inadequate labels for characterizing neural mechanisms. Instead, we advocate considering the component operations and representations of mnemonic processes in isolation, when examining their neural underpinnings. For the neuroanatomical organization of memory, the evidence suggests that pattern completion is recapitulated widely across cortex, but the division of labor between cortical sites can be explained by representational content.
