These toys range from the cheapest and simplest to sophisticated costly models for play education. Looking at the market offer, it can be stated that mechatronic toys are being produced, which are intended for children of several months. When developing children’s and educational robotics, it is, therefore, necessary to take into account the psychomotor development of the child. Respecting or not respecting it has a major impact on the success of the toy for the consumer and the fulfillment of the educational goal for which it is intended. Last but not least, in connection with the child’s development, the question arises as to what ergonomic principles, when designing toys intended for children depending on age, need to be respected and implemented into solutions to eliminate problems related to the development of children’s and educational robotics. The subject of interest in the article is the age groups of children from birth to preschool age. The aim of the article is to identify which factors in the construction of children’s robotic toys for the youngest children up to the period of preschool age are key from the point of view of ergonomics.</p> </abstract>ARTICLE2021-09-01T00:00:00.000+00:00Retail Service Quality Scale (RSQS) as an Example of Quality Service Scale Used in Traditional Trade<abstract> <title style='display:none'>Abstract</title> <p>We make purchases almost every day. We buy some products very often (e.g. food), others less often (e.g. furniture, car). Shops, selling products to customers, are not their producers, but rather provide them with services (commercial service). It is important that the customer, after making the purchase, is satisfied not only with the product, but also with the purchasing process itself. In order to determine what are the reasons for customer satisfaction or dissatisfaction, it is necessary to assess the quality of services, i.e. the process of making purchases by customers. In the available literature, there are many methods that are used to assess the service quality. However, their use is associated with the need to identify attributes that could well describe the service provision process, but also be a source of knowledge about customer satisfaction. The Retail Service Quality Scale (RSQS) developed by Dabholkar and his colleagues is applicable to assess the quality of services provided by shops, so it can be a ready-made tool that does not require the researchers to define attributes, as would be the case when using traditional methods. The aim of the paper was to assess the quality of operation of a traditional shop using the RSQS methodology. This study was carried out using a paper questionnaire that contained the attributes proposed in the RSQS. The survey was conducted among customers of a selected shop. The analyzed results made it possible to determine the quality level of commercial services provided by the research shop and to indicate its strengths and weaknesses. Additionally, the possibility of using the ready-made RSQS scale to assess the quality of commercial services provided in Polish economic realities was confirmed.</p> </abstract>ARTICLE2021-09-01T00:00:00.000+00:00Analysis the Influence of Steel Sheet Production Technology on the Quality Products in Steel Service Polska<abstract> <title style='display:none'>Abstract</title> <p>The process of production and processing and preparation for distribution of steel products is associated with the requirements of maintaining appropriate procedures. They allow, in accordance with industry standards to avoid unforeseen problems associated with the preparation, implementation and finalization of activities aimed at achieving the intended purpose, which is a finished product of adequate quality and customer satisfaction. It is not always possible in the production process to meet all the requirements and technological, organizational and human factor recommendations. The analysis of selected problems, which includes the content of the article allows to significantly determine the factors and parameters associated with the preparation and technical implementation affecting the implementation of the intended objectives of the company, i.e. achieving an appropriate level of quality and minimizing the defects in the process of steel sheet preparation. Analysis of selected parameters was made on the basis of data obtained in the company operating on the international market Company Steel Service Poland. At the request of company representatives, the name has been changed due to the production data used in the article, which may be considered as sensitive. The article contains data based on research carried out in Steel Service Poland. Selected problems are the subject of analysis of steel sheets cutting processes with the analysis of causes of customer complaints with reference to the produced steel products. Selected steel grades and factors affecting the efficiency of the technological process are presented. The analysed set of factors translates into the level of product quality and reduction of arising defects.</p> </abstract>ARTICLE2021-09-01T00:00:00.000+00:00The Prospects of Abrasive Treatment of Tough-To-Machine Materials<abstract> <title style='display:none'>Abstract</title> <p>In current conditions, great attention is paid to the quality of parts, which is in many ways determined by finishing operations of mechanical treatment, with surface grinding being the most widespread. Grinding process efficiency, abrasive tool wear intensity, machined surface quality and other features of grinding process depend on properties of the environment, where the cutting process takes place. Forced changing of conditions of this environment is one of the ways to control and optimize the grinding process, which can be reached due to finding new technological decisions. One of the most promising directions to solve this problem is the process of face grinding with discontinuous grinding tool and supply of cooling fluid or air in the cutting zone directly. Carried analysis of features of face grinding has shown that heat density can be decreased by the usage by grooved wheels with vortex air cooling or by supply of cooling-lubricant technological fluid. Obtained dependences of temperature field of part surface during grinding establish the influence of the length of working shoulders and grooves, vortex tubes number, outflow rate, temperature and flow rate of cold vortex flow of air. These data provide conscious control over the process of discontinuous face grinding by changing wheel grain size and grinding speed.</p> </abstract>ARTICLE2021-09-01T00:00:00.000+00:00Private and Public Sector Employer Actions for Home Office Workers During the COVID-19 Epidemic<abstract> <title style='display:none'>Abstract</title> <p>A research was conducted among the employees referred to work in the home office in connection with the announced state of the epidemic in Poland.

Case Study<abstract> <title style='display:none'>Abstract</title> <p>In hard coal mines with methane, there is often a need to apply demethylation in order to keep the methane concentration not exceeding 2% in the ventilation air. The basic demethylation method in longwall areas is through drainage boreholes made in the roof rocks of the coal bed, from top gate, in front of the longwall. The drainage boreholes are usually made in bundles, in a fan-shaped arrangement, with several boreholes in each bundle. The paper presents the results of measurements and tests of the efficiency of a bundle of four drainage boreholes drilled approximately 100 m in front of the longwall face. The efficiency of individual boreholes was analyzed in time and depending on the distance of borehole outlets from the longwall face. It was found that there is a large variation in the extraction of air-methane mixture by individual drainage boreholes, as well as large differences in the efficiency of individual drainage boreholes during the longwall extraction process.</p> </abstract>ARTICLE2021-09-01T00:00:00.000+00:00Psychology of Creativity and Innovation in Engineering and Business Curriculum<abstract> <title style='display:none'>Abstract</title> <p>The paper describes the development of a new course.

The research shows that the use of modern technologies is not reserved only for industrial solutions, but can be applied in common use. Solutions based on artificial intelligence can provide solutions to many problems of the modern world. This is particularly visible in the era of challenges related to ecology (e.g. minimization of paper consumption) and expectations of fast access to information regardless of place and time. Treating chatbots as a tool supporting the customer in current activities, quick problem-solving shows the potential and care for the image of the producers. Developing the functionality of virtual assistants used for marketing activities with the functionality of technical support can bring tangible benefits both in the economic and social spheres. It should be noted that electronic versions of documents, knowledge transferred in an interactive form can be easily updated and presented in different forms. This increases the attractiveness of transmitted knowledge, users can choose the appropriate form, and access to these resources becomes easier. Artificial intelligence-based tools in the form of chatbots (also called virtual assistants) seem to be a solution worthy of interest. This paper presents the process of developing a virtual assistant to support the maintenance and repair activities of small household appliances. A chatbot aims at gathering in one place and then providing dedicated knowledge resources to an individual user on a just-in-time basis.</p> </abstract>ARTICLE2021-10-09T00:00:00.000+00:00Towards a Self-Service Approach in the Printing Industry. An Investigation of State of the Art Technologies Along with Industry 4.0 Changes<abstract> <title style='display:none'>Abstract</title> <p>It is commonly believed that the current economic state of many countries is at the stage of the fourth industrial revolution. The changes resulting from this revolution are affecting all sectors of the economy, including the printing sector. The aim of this article is to analyse the state of the art technology in sheetfed printing and then to identify the challenges for further changes in the technology of this type of printing as well as technological and organisational changes in the processes of preparation and realisation of printing products.

This activity in Polish underground mines causes numerous problems, which until present have not been solved. Currently, transport and assembly are carried out manually, while the roadheader and suspended rail are used only to a small extent. Therefore, the modular installation and transport assembly was developed jointly by FAMA Sp. z o. o. and AGH University of Science and Technology. The solution in question enables performing a number of functions (including transport and assembly of all kinds of support arches), which are not available in currently manufactured equipment. The proposed manipulator solves numerous problems occurring during the installation of the steel arch support in an underground mining excavation and significantly improves the process of drilling galleries. This innovative solution considerably differs from the existing ones, and its greatest advantage is versatility with regard to the cross-section and equipment of the roadway, as well as a wide range of functions. In addition, it can also be used for reloading works. The modular installation and transport assembly together with a platform, a temporary mechanized roof support and a mining machine, make up a mechanizes roadheader complex, which enables continuous mining, loading and installing the permanent support in underground workings.</p> </abstract>ARTICLE2021-09-01T00:00:00.000+00:00Determination of Coal Cutting Forces Using the Cutting Head of POU-BW/01-WAP Device<abstract> <title style='display:none'>Abstract</title> <p>The paper presents a method for measuring and recording the forces involved in the coal cutting process. Moreover, a method for visualization of all forces involved in the cutting process was described. In the following part, the construction and principle of operation of a device for determination of forces involved in the cutting process (coal mining), referred to by the author as POU-BW/01-WAP, are presented. Resistance extensometry was used to measure the forces. This is the only device in the world that determines two of three force components that take part in the cutting process. For this purpose, two independent measuring blocks were used, which are strain gauges of force: cutting (F<sub>s</sub>) and knife pressure (F<sub>d</sub>). In order to register these forces, a real mining knife used in longwall shearer drums was applied – i.e. tangential-rotary. The equipment has the ATEX certificate allowing for operation in real conditions as a device intended for use in potentially explosive atmospheres – in accordance with the directive 94/9/EC. It has received many awards at world fairs for inventions and innovative solutions.</p> </abstract>ARTICLE2021-09-01T00:00:00.000+00:00An Overview of the Impacts of Geological Hazards on Production<abstract> <title style='display:none'>Abstract</title> <p>Throughout history, human beings have been affected by the ongoing events in their environment. While some of the events take place in the sphere they live on, some of them are in the way that events outside the earth affect the world. Necessary measures should be taken on time and in place so that people are not adversely affected or at least minimally affected by the aforementioned events. Geological hazards are the most important risks that occur in the environment of human beings and have a high probability of damaging people’s life and property. In terms of risk management of geological hazards, which are divided into four main groups as seismic, hydro-meteorological, terrain instability and volcanic hazard and have their own characteristics, the efforts to prevent and reduce losses for each of them also differ within themselves. In this review article, geological hazards were introduced in general by giving various examples from the world, the effects of geological disasters on the economy and production were discussed, and the points to be considered for each risk were tried to be emphasized.</p> </abstract>ARTICLE2021-09-01T00:00:00.000+00:00Statistical and Econometric Analysis of Selected Effects of COVID-19 Pandemic<abstract> <title style='display:none'>Abstract</title> <p>The paper examines the impact of the COVID-19 pandemic on macroeconomic activity in the selected European countries. The studies are based on monthly and quarterly indicators of GDP, unemployment rates and key indicators of the tourism sector. To present how COVID-19 has affected these macroeconomic variables, statistic data from the three periods are compared. Namely, data are collected from the pre-pandemic period, i.e. the fourth quarter of 2019 as the reference period, the second period covers the first quarter of 2020 and means the beginning of the pandemic, and the third one covers second quarter of 2020, during which the pandemic has spread to all the analyzed countries. The following statistical techniques are used in the research: regression analysis, the hierarchical grouping of agglomerations, k-means method, and selected non-parametric tests (Kruskal-Wallis test for a selected group of countries and Kolmogorov-Smirnov test for a selected pair of countries). The results show the significant impact of the pandemic on the level of gross domestic product, unemployment rate and turism sector. In most cases, a correlation between incidence of COVID-19 infections, unemployment rate and GDP is observed. The statistical techniques also allow to demonstrate the similarities and differences in the response of the economies to the COVID-19 pandemic. Central Statistical Offices of the selected countries are the main data source and for all calculations Statistica version 13.3. is used.</p> </abstract>ARTICLE2021-09-01T00:00:00.000+00:00Quality Policy With Regard to the Orientation Towards Improvement Among Industrial Enterprises with Various Types of Organizational Culture<abstract> <title style='display:none'>Abstract</title> <p>The article is one of a series of articles (Molenda, 2020) in which the results of studies on the assessment of the quality policy in industrial enterprises operating in Poland have been described. When carrying out the surveys in the years 2015-2019, in addition to the quality policy, the type of organizational culture of enterprises was identified, among other things. This allowed to divide enterprises into 4 groups, depending on the dominant type of organizational culture identified according to the Cameron-Quinn methodology (Cameron K., Quinn R. 2003). This study compares the quality policies of these enterprises in terms of their orientation towards improvement characteristic of the TQM philosophy. The first part of the article describes the issue of the quality policy in the context of organizational culture. The body of the article contains the results of studies conducted among 166 enterprises. A preliminary statistical analysis of the results allowed to answer the question of what is the level of orientation of the implemented quality policy towards improvement and whether this level varies depending on the organizational culture.</p> </abstract>ARTICLE2021-09-01T00:00:00.000+00:00Determination of Traffic Noise on the Selected Area of the City of Zabrze<abstract> <title style='display:none'>Abstract</title> <p>The article is a substantive summary of research conducted by the Institute of Production Engineering of the Silesian University of Technology in Zabrze, covering the determination of ways to reduce traffic noise in the selected area of the city of Zabrze using measurement and simulation methods.

According to the Central Register of Vehicles (CEPiK) maintained by the Ministry of Digitalisation, the number of motor vehicles registered in Poland in 2019 was 23,878.8 thousand units. Among them, 18,302.4 thousand passenger cars were registered. The constantly increasing number of vehicles on the road has a significant impact on the deterioration of road capacity and drivers’ frustration with parking, especially during rush hours in the centres of large cities. Hence, urban logistics, including the country’s parking policy, is extremely important to a significant proportion of citizens. Unfortunately, citizens have different perspectives on parking issues. Most drivers expect to be able to leave their car as close as possible to their destination, while some residents, especially non-motorised ones, are against the conversion of free city space into car parks. In response to the presented issues, a comparative analysis of selected types of car parks was carried out. This analysis was one of the stages of the project entitled: “Analysis of the environmental impact of a vertical parking solution using life cycle assessment at the design stage” carried out at the Silesian University of Technology.</p> </abstract>ARTICLE2021-09-01T00:00:00.000+00:00en-us-1
