Published: June 2021

Abstract

Study aim: The purpose of this research was to examine the effects of different times of day on static and dynamic balance performance.

Material and methods: Thirty male individuals (age 22 ± 1.2 years, BMI 23.4 ± 1.3 kg/m2, height 178.5 ± 6.52 cm) volunteered for the study. The participants performed static and dynamic balance tests at 10:00, 15:00, and 20:00. Static and dynamic balance were measured using Y Balance Test (YBT) and the Balance Error Scoring System (BESS). One-factor repeated measures ANOVA with the LSD post-hoc procedure was performed to examine balance changes in the morning, afternoon, and evening.

Results: Results indicated a significant difference in static balance scores at different times of day (p < 0.05). Post-hoc analysis indicates that mean of errors in afternoon exhibits significantly smaller than those of morning (p = 0.024), and evening (p = 0.029). Other results showed significant differences in dynamic balance at different times of day (p < 0.05). Post-hoc analysis indicates that means of reaching distance in afternoon exhibits significantly larger than those of morning (p = 0.032), and evening (p = 0.026).

Conclusions: The results provide strong evidence about the effect of different times of day on performance.

AbstractThe study aimed at evaluating the contents of tenancy agreement entered into between lessors and lessees in Osogbo, Owode-Ede and Ede Metropolis in Osun State (Nigeria) from 2011 to 2020 in order to determine its adequacy in the face of the Post-COVID-19 pandemic in Nigeria. A questionnaire survey approach was adopted to achieve aim of the study. Findings of the study revealed steady dwindling of rental market transactions with deteriorating landlord/tenant relationship caused by disagreement on tenancy agreement related issues leading to default in rent payment, rent review period and renewal. Findings also indicated a low ebb experience in the rental market due to the economic downturn resulting from, among other factors, the lockdown policy, which impoverished Nigerians to the extent of struggling to make ends meet. The study further found that 86.3 % of the tenancy agreements were inadequate in content and execution as basic tenants’ remedial provisos were not included in most of the agreements. The study provided pertinent information that could be used as baseline information for tenancy agreement preparation, enhancing landlord (lessor) and tenant (lessee) relationship, and guiding rental real estate investment decisions in Nigeria.

Published: June 2021

Abstract
Protection of the head structures is a requirement in many sports where a person is exposed to injuries that threaten life or health. In horse riding accidents occur often, resulting in serious head injuries. The analysis of the available literature shows that the helmets used now protect human head structures in a small percentage. The aim of the research was to analyze the degree of protection of the human head using available helmet structure and a new solution for the Energy absorbing layer in helmet that absorbs Energy from impacts. The research was divided into two stages. During the first one, a simulation was performer under dynamic conditions simulating the rider’s fall and the contact of the head with ground (impact from the side). In the second stage, three structures of the absorbing layers were developed, i.e. honeycomb, auxetic, mixed with three three wall thicknesses (1 mm, 2 mm and 3 mm respectively) and two materials were used: the currently used EPS and the aluminium alloy used in the motorcycle helmet.

Abstract
Artificial neural networks (ANN) are a powerful tool in the decision-making process, especially in solving the complex problems with a large number of input data. The possibility to predict the work-related injuries in the underground coal mines, based on application of the neural networks, is analyzed in this work. the input data for the network were obtained based on a survey of 1300 respondents. After analyzing the input data influence on the network output, 14 most influential inputs were selected, with help of which the network correctly predicted whether the worker would suffer the work-related injury or not, with 80% precision. The two models were developed, based on the multilayer perceptron (MLP) and radial basis function (RBF) networks. The two models’ results were compared to each other. The sensitivity analysis was used to select the most influential parameters, like mine, age of miners, as well as their work experience. The parameters were further analyzed by use of the descriptive statistics. The selected parameters are direct indicators of problems that can cause injuries. The obtained results point to the fact that the work-related injuries can be successfully predicted by application of the artificial neural networks. The proposed models’ importance is reflected in the clear indicators for enforcing the stricter occupational safety and organizational measures in order to reduce the number of work-related injuries in underground mines.

Published: June 2021

Abstract
The aim of the study was to indicate the reasons for non-compliance of aluminium rim castings and, using quality management instruments (Pareto-Lorenzo diagram and 5WHy method?), elimination or reduction of non-compliant products. The object of the research was an aluminium rim, while the diagnostic process of the object of the research was based on the quality control of the chemical composition of the casting, the control of mechanical properties and the control of the continuity of the material structure by radiographic and microscopic methods. On the basis of the research carried out, it was found that a sensitive casting area is the front edge of the rim rim - a significant number of porosity clusters were identified in this area. The reason for their occurrence was also specified - too rapid flooding of moulds, which resulted in gassing of the alloy. The identified cause had its origins in human resources mismanagement, namely the lack of training of the newly recruited employee. So far, the company has not carried out analyses of quality problems with the use of a sequential quality management methodology, so the implemented corrective actions have not always led to the full achievement of quality objectives. The presented sequential method, which is a combination of diagnostic and control tests and quality management instruments, is a universal way to monitor the level of quality of products and to quickly correct nonconformities.

Published: June 2021

Abstract
The aim of the study was to implement an integrally configured method of quality control of frictional welding of piston forgings intended for Diesel Man trucks. The use of the method (consisting of the 5W2H method, the Ishikawa diagram and the ABCD - Suzuki method) would contribute to the detection of the causes of non-compliance and consequently to the elimination of non-compliant products. Steel pistons have become the subject of research due to significant problems with maintaining their expected level of quality after the introduced structural and technological changes. The proposed method has helped to identify the root cause of non-compliance. It was: incorrect design of the combustion chamber in terms of diameter and depth. The study shows that it is advisable to use an integrated approach to finding the causes of quality problems on the example of the friction welding process. This was a new solution for the company, as no in-depth analyses of quality problems using a sequence of quality management techniques have been carried out so far.

Authors: Niciejewska Marta 
Published: June 2021

Abstract
Every employer is responsible for ensuring safe and hygienic working conditions. According to the Labor Code and the relevant regulations, the elements of safe and hygienic working conditions in each enterprise are very similar. Differences arise when a specific industry or special psychophysical needs of an employee are taking into consideration. There is a specific group of employees for whom the working conditions organized by the employer in terms of occupational health and safety differ from the average working conditions. In the paper the needs, limitations and psychophysical possibilities of professionally active employees with sensory integration disorders are analyzed. In this purpose the direct interview with elements of open observation was used as the research method. The results presented in this paper are the small part (initial diagnosis) of the large project. Preliminary conclusions confirm the difficulty of adapting employees with sensory integration disorders to a universal work environment and the great need to organize special working conditions for them.

Published: June 2021

Abstract
The enrichment of the society and the consumptive lifestyle caused that customers buy more and more, having different, often very high requirements as to the purchased products and services. They often do not realize that production of such products requires more and more materials, energy and other means of production. All this leads to high exploitation of the environment. Even if the resources of the natural environment are not exhaustible, they do not keep up with their rebuilding at this pace of exploitation. That is why social awareness and responsibility both of producers and customers play such an important role. They are one of the instruments needed to operate in accordance with the concept of sustainable development. The aim of the research was to examine social awareness and responsibility among customers of service enterprises. The research was conducted with the use of an online survey, which allowed to show whether the customers of such enterprises are interested in the concept of the sustainable development, if they take it into account when using various services. The need for environmental education was indicated, which could strengthen the social awareness and responsibility among Polish customers.

Abstract
The interaction between universities and business in the field of innovation is practically relatively simple and straightforward, but at the same time requires careful construction of complex processes. All these processes of interaction are directly related to people and the organization. The term “stakeholders” applied only to employees of the enterprise, but due to the current changes, it has acquired a social orientation. The term is now common in many scientific publications. It can be applied to the organization itself and outside the organization in the organization of interaction between universities and business. The purpose of the study was to define and identify the interactions between universities and enterprises, depending on the type of activity. The HEIinovate tool was used to get the result among 2 universities in Kazakhstan and Poland. The results of the study show that the identification of internal stakeholders of interaction between universities and business in the field of innovation plays a key role in the joint work of both parties.
