    A virtual environment was developed for PC and Android to be used with a desktop display and the Gear VR, respectively. The goal with it is to measure and enhance the spatial skills of people, because the latter can be achieved by solving simple geometric problems. Originally, this virtual environment consisted only of three such tests, namely the Mental Rotation Test, Mental Cutting Test and Purdue Spatial Visualization Test. Measurements were done in the past with these tests, but now the Heinrich Spatial Visualization Test is also included in the virtual environment. In this paper, its implementation and future measurement plan are presented.

    With the rapidly emerging trend of employing Artificial Intelligence technologies within modern economics. This study is an attempt to fill the research gap associated with the factors that have influence with the adoption of artificial intelligence in human resources information systems on HR-leaders intention to use it. It empirically investigates the influences that trust, technological readiness, facilitating condition and performance expectancy on HR-professional’s behavioral intention to use AI in HRM. Besides, examine the moderating effect of age and experience on the proposed associations. Data were collected from by online questionnaire from 185 HR managers. A structural framework was introduced to test the relationship between study latent variables. Result exhibited that trust and performance expectancy has a significant influence on HR-professionals behavioral intention to use AI-HRIS. Trust and technological readiness showed a significant influence on HR-professionals performance expectancy of using AI-HRIS. While facilitating condition, organizational size and technological readiness did not show a significant influence on HR-professionals behavioral intention toward using AI-HRIS. Lastly, Age and Experience did not have a moderating effect on trust and performance expectancy association with the behavioral intention toward using AI-HRIS. The findings of this study contribute to the theory development of information technology diffusion in HRM.

    Annual accounting statements are an important source of information within business relations amongst companies. However, it should be noted that due to their aggregate nature, the necessary information and through that the necessary knowledge can only be obtained from the two fundamental parts of the annual statements (balance sheet and profit and loss account) if the notes on the account contains the information that contributes to the more comprehensive interpretation of the other part of the annual statement. Beyond that, the notes to the financial statement have to help the presentation of a reliable and realistic overall image. In the notes to the financial statement, depth and detail of the disclosed information are not specifically stated, therefore their professional evaluation is left to the given enterprise. My basic purpose is to illustrate a comparison of the information content of the notes on the accounts between information technology services and sports activities. By means of text mining, we analyse the extent to which the notes on the accounts are in conformity with the Accounting Act.

    Because of present day information technology, there is neither need to plant complicated computers for more millions price if we would like to process and store big amounts of data, nor modelling them. The microprocessors and CPUs produced nowadays by that kind of technology and calculating capacity could not have been imagined 10 years before. We can store, process and display more and more data. In addition to this level of data processing capacity, programs and applications using machine learning are also gaining ground. During machine learning, biologically inspired simulations are performed by using artificial neural networks to able to solve any kind of problems that can be solved by computers. The development of information technology is causing rapid and radical changes in technology, which require not only the digital adaptation of users, but also the adaptation of certain employment policy and labour market solutions. Artificial intelligence can fundamentally question individual labour law relations: in addition to reducing the living workforce, it forces new employee competencies. This is also indicated by the Supiot report published in 1998, the basic assumption of which was that the social and economic regulatory model on which labour law is based is in crisis.

    Strains and stresses in loaded and photoelastically coated structural members can be determined using the PhotoStress method. The quantitative values of variations in the principal strains (stresses) and their directions could be employed to get the strain or stress components field on the entire coated surface. In the PhotoStress experiment, isochromatic fringes give qualitative and quantitative information. It provides a source of information on the directions and magnitudes of principal strain and principal normal stress on the surface of photoelastic coated parts. This article reviews the principle of using PhotoStress analysis to measure the residual stress and provides the boundary condition of using this method.

    The term “information society” first appeared in Japanese social science in the early 1960s (Z. Karvalics, 2007). The interpretation of the concept has undergone significant changes over the past decades, showing that dynamically developing societies, which are undergoing constant changes due to the rapid development of information, information management and the dynamism of the digital world. The close relationship and connection between information and information technology has become a fundamental factor in the societies of today, the organizations life, which generates inevitable, sometimes serious debates and profound changes. Economic operators must necessarily be resilient to technological change. We should think of the time of the Industrial Revolution, when modern weaving machines flooded the factories. Otherwise, a resilient organization will not survive in an evolving and ever-changing dynamic economic environment. Of course, this is true of agriculture as well, just as it is for other sectors of the national economy. On the one hand, my assumption on the basis of which my questionnaire was compiled was that enterprise management systems are increasingly used by enterprises in agriculture due to the diversification of activities. At the same time, I assumed that the size of a business could influence the use of information technology (hereinafter IT), so I hoped that my research would provide reliable data on this as well.

    In recent years, the global use of contingent workers is rapidly increasing despite the increasing quantity of artificial intelligence applications in business. The question is "how these companies leverage the use of artificial intelligence to enhance contingent workforce's management?". The ideal goal of this paper is to develop a purely conceptual application of innovation, artificial intelligence (AI) adjacent to contingent workforce management(CWM). The researcher used qualitative information gathered from various authors and observations to reinforce the usage of AI. One of the critical tools to integrate with contingent workforce management for reduction of time spent on human resource administrative tasks is AI. There must be a transformation of thinking, accepting positive organizational change, utilization of technology and openness to new technology to foster  AI. Along with that, integrating contingent workforce management with AI reduces risks and costs, increases efficiency and quality of work. Innovation and Artificial intelligence have been used in five pillars performance of contingent workforce management to mitigate the challenges associated with it.

    For agriculture, precision farming means the future by increasing incomes and reducing environmental loads at the same time Precision management produces a surplus in yield, revenue, result, but not immediately. The additional income potential is expected to increase by 20% to 50%. Farms mostly introduce precision farming in order to relieve workers. However, many farmers are afraid of the use of new technologies, but the use of information technology in agriculture will be unavoidable. Technology is fundamentally expensive, not even widespread, and farmers use only a few technology elements. Moreover, following the precautionary principle technology used in farming covers only a part of their agricultural land. So farms need to learn to produce more precisely than before in a knowledge-based manner.

    The aim of our study is to reveal the fit of digital space into current and future trade and to assess the effects of digitization on Hungarian trade strategies. The information gathering and purchasing habits of consumers have changed dramatically in recent years. Consumers today make buying decisions based primarily on convenience, effectiveness (fast and convenient access to products at adequate price/value ratio), and experience. Adjusting to these trends, traders developed novel trading strategies, and the use of achievements of digitization is an integral part of these strategies. One aspect of digitization is the increasing global development of e-commerce. The Hungarian online commerce have also been expanding significantly from year after year: based on 2018 data, domestic and foreign online sales volume have passed 1000 billion HUF. The Hungarian online consumers buy on the Internet more and more often and at greater and greater value. The online shopping on virtual reality platforms may make this purchase mode more experiential. Webshops have to meet new consumer needs, and deliver the ordered products as soon as possible, preferably within 24 hours. An increasing number of parcel delivery options has begun becoming more and more popular (e.g., automatic parcel terminals, pick pack points). However, traditional channels should not be buried, either. Their obvious advantage is that consumers can take their choice based on multiple senses and it also gives them more room for impulse buying. Combined with the digital technology compliant with contemporary requirements, this can offer a complete shopping experience. Nowadays, recognizing this need online and traditional channels have been mixed in several cases (e.g., multichannel, omnichannel, cross-channel sales) and offer several options for consumers during the purchase process. The sales area optimization of traditional shops and the buyer paths aided by digital technology (e.g., digital shelf labels) are designed for the buyers’ convenience. The newest innovations imply automation of the buying process making the whole process more convenient and more personalized with the use of sensors (e.g., Amazon Go) or robots (e.g., Pepper). In our future purchases, digital personal assistants will appear as digital versions of sales personnel.

    The lack of physical activity and the growing prevalence of a sedentary lifestyle are urgent public health problem worldwide. The problem is also typical of the young population, especially university students, who spend most of the day in a sitting position. Technological development is one of the catalysts for the rise of a sedentary lifestyle, nevertheless, thanks to this, many devices have appeared on the market that can be used to encourage physical activity. The widespread of wearable activity tracker devices – wristwatches, wristbands – among the population shows a constantly increasing trend, with a parallel increase in the amount of data collected about ourselves (step count, calories burned, heart rate). The main goal of the present study derives from the recognition of the gap in this field in the domestic sports science literature therefore our focus is on modern information technology tools in the dimension of physical activity. The aim of this study is to assess the attitudes of the university student population towards activity-tracking devices. We conducted a cross-sectional online quantitative survey (questionnaire) among DE GTK students. 340 people filled out the questionnaire correctly. In addition to descriptive statistics, parametric and non-parametric tests (Pearson's chi-square test, Fisher's exact test, t-test, Mann-Whitney test) were used to examine the relationships. The results of the statistical tests were considered significant if p<0.05. We performed the distribution of the variables using the Kolgomorov-Smirnov test. The majority of respondents (55%) have already tried some kind of wearable device that measures physical activity. Every third student (34%) are currently using their device. Those who have not tried these devices so far indicated the price as the primary deterrent. 32% of the students plan to invest in such a device in the future. 39% of device users use an activity tracker bracelet, while 61% use or used a smartwatch. In terms of sex, we did not find any differences in asset ownership. The primary goal of the students (66.8%) was to track their physical activity. The most frequently used function was tracking the number of steps, indicated by 81% of the respondents, followed by heart rate measurement (67%). Most of them (69%) set some kind of goal regarding their number of steps. According to every third student, they moved more as a result of the device and managed to maintain the increased level of physical activity. 44% of the students claimed that their physical activity did not change despite using the device. Students tend to disagree with the positive statements related to the devices in connection with a healthy lifestyle. Although the present study suggests that wearable devices have an impact on students and they track their measured data, it is questionable whether the devices themselves are enough of an incentive for students to develop a healthier lifestyle.

    Thanks to various technologies, such as nanotechnology, the next decades will completely transform the individual production processes and sectors. With the rapid advancement of information technology, the digitalization and automation of industrial processes pose new challenges for food business operators. Hungarian food companies will be able to keep up with their competitors and be the winners for the next decades if they can successfully adopt these technologies. However, this requires a strong focus on digitization, digital strategy, and directing investment, technology change and R&D activities in this direction. Digitization is one of the decisive directions of the future, which is why I felt it essential to study the level of digitization of Hungarian food companies, IT infrastructure and Internet usage, the use, and role of enterprise management systems, decision support and business analysis tools, and business readiness, Industry 4.0 technology change. Based on the 205 evaluable responses to the questionnaire, it can be said that only a tiny proportion of Hungarian food companies have a digital strategy and only a few have digital transformation.

    In terms of production value, the food industry is the third-largest in Hungary, the first in Hungary in terms of the number of employees, and the first in Europe in the processing industry, as well as a significant user of resources. The research examined the state of art of digitalization readiness, focusing on I4.0 technologies, which supports the management to operate more efficiently the enterprise and to make better decisions. So the focus was on integrated enterprise information systems, management support systems, business intelligence systems, industry 4.0 technologies, and issues related to their application. The analysis based on an online questionnaire survey the request sent to 4.600 enterprises, the response rate was 5% which was representative of the branches of production, covered the Hungarian food and beverage manufacturing sectors in 2019. The companies were asked the most critical technologies in development, going towards Industry 4.0. The research tools were LimeSurvey, Mailing List Server, Excel, Power BI (Desktop, Publishing Server to distribute the results). The used analysing methods were making calculations, pivot tables, models, dasboards. We found that a significant portion of businesses, 78 %, use mobile devices in the manufacturing process. The three most relevant digital technologies are geolocating (GPS, GNSS), cloud computing, and sensor technology. The current level of digitalization and integration cannot be said to be high, but respondents are very optimistic about expectations. Improvements are expected in all areas in the next 2-3 years in terms of digitalisation and integration. Vertical integration involves, first and foremost, cooperation with partners in the supply chain. Horizontal integration means close, real-time connectivity and collaboration within the company. Unfortunately, between 6% and 15% of SMEs (approximately 9% on average) and large enterprises, 36% have a digital strategy. According to the survey, the sector needs significant improvement and creating a digitalization strategy.

    The increasing competition and globalization have changed the micro- and macro environment of companies worldwide. The number 4.0 marks the fourth industrial revolution, bringing information technology and automation closer together leading to fundamental changes in production methods. It is not only about the penetration of technology but also about the paradigm shift in business processes. Industry 4.0 is becoming a daily reality for domestic companies as well, giving rise to the era of high-level interaction among production resources and different players. Industry 4.0 will transform the structure of production and change global competitiveness giving enterprises new opportunities to create added value. In my study I presented the concept of Industry 4.0, its framework and innovative technologies. I described the intelligent logistics solutions and the most important advantages of Industry 4.0. Essentially, the use of these tools include in addition to the explosive development of industry the digitalisation of the entire economy affecting society as a whole. It is of great importance that small and medium-sized enterprises also respond to new technological opportunities otherwise will significantly lagging behind in the digital transition.

    Small and medium-sized enterprises are the engines of Europe's economy. This is demonstrated by the European Small Enterprises Charta, adopted in 2000, and by the fact that this sector employs more than 90 million people. Appropriate information and communication technology is essential to maintain their ability to function effectively and competitively. They need to know how to use these technologies for their smoot growth in productivity. The purpose of our study is to assess the regional ICT penetration of the Hungarian SME sector and compare this to that of the EU Member States.

    Globalization, the spread of multinational companies and the enormous development of information technology can lead to a new trend in employers’ requirements. However, being employed by an international company is a real possibility for any employee in any part of the world. Even if they do not have to work abroad, employees may have to function in a multinational environment in their home countries. A favourable combination of intercultural competencies is a key factor in the selection and development of employees. A possible way of measuring these competencies can be the Multicultural Personality Questionnaire (MPQ). First of all,on the employers’ part, it is important to clarify the exact requirements and competencies (dimensions) to be able to draw up an ‘ideal profile’. We prepared two versions of the MPQ (91-item; 5-dimensional) and used them to test employers’ requirements in the selection process regarding the dimensions of cultural empathy, open-mindedness, social initiative, emotional stability and flexibility. This study describes the results of a focus group interview, which took place in 2017, revealing the importance of multicultural competencies from the employers’ point of view and examining the conditions of the adaptability of the two questionnaires. We used the focus group method to find out in what conditions the questionnaires canbe used in a selection process. What possibilities and limits are therefor using the direct five-dimensional questionnaire? What aspects do we need to take into consideration in expressing and interpreting the requirements in the results of the test?

    Since the 70's, when huge sulphidic open pits were developed, the acidic rock drainage (ARD) become the leader problem of the sulphidic mining industry. Although the recycling is an essential technology, it cannot cover the demand alone, thus mining activity needs to continue. Acidity in mine drainage commonly requires most of the attention, but the main problem is the caused elevated level of metal mobility and leaching, which are generated by the increased rates of sulphide weathering under acidic conditions. The Itos mine is a polymetallic vein deposit in Bolivia, had been mined for silver and tin until 1990, leaving behind much and huge tailings and mine waste heaps, where quite often the pyrite content exceeds 10 %. Serious ARD effects take place in the mine waste heaps. These processes can be well characterized with the pH 1 or 2 of the seepage water, which forms serious alteration in the waste itself and the neighbouring rocks. In three consecutive years, the pyrite oxidation rate was investigated on the same 7 samples by humidity cell test. 5-6 months pauses were left between the humidity cell test periods, which mimics the alternation of wet and dry periods, typical for the place. The results give much more information, than the oxidation rate in the individual test periods, showing the changes by time. This applied method gave good result to characterize the behaviour of the waste in long-term. The column test was complemented with mineralogical analyses, such as electron probe micro analysis. The mineralogical and column test analyses show, that the changes of the pyrite oxidation rate split the samples into three different groups, one where the oxidation rate decreases, second where it increases with time and the third where oxidation rate is maximal and stays stable for several years.
