Use of IoT Tools to Support the Decision-making Process
125-141Views:225Nowadays sensor networks and other systems, based on the IoT concept demonstrate the benefits of their usage, which includes the support of the decision-making process, therefore achieving an optimal result in the context of more and more fields. In this experiment, an additional sensor network has been developed based on a modular system derived from a previous development by means of a target-specific modification of the required modules to measure environmental data in a drying chamber used in food industry. The main objectives include the development of the device, the verification of the measurements of the factory-built device, providing an interface, which is able access the measurement data and after gathering experience from the usage, further developing the system and extending the functionality of the web application. The built-in data acquisition and control system stores the data of the measurements in the form of text files, while our additional data acquisition and control system uses a unified measurement database to store the data. According to the structure, a task-specific application has been developed in order to unify the two sources. Analysis of collected data was performed after running the ETL (extract, transform, load) algorithm converting the transaction-oriented database. The experiment shows so far the benefits of the multi-point measurements by a significant difference between the measured values, so we certainly consider further developments.

Potentiodynamic Study of the Effects of Nickel on The Electrodeposition of Zinc from Chloride Media
15-24Views:126Abstract. The potentiodynamic experiments of the nickel effects on the zinc electrodeposition have been done to understand the impact of Ni impurities on the electrowinning of Zn from spent pickling liquor. The nickel chloride solutions of Ni concentrations 90 and 1 g/dm3 were used as the electrolytes. The latter was also mixed with 90 g/dm3 Zn in the experiments. All the runs were carried out at room temperature with 40 mV/s continuous polarization speed and with 1/s sampling rate. It was observed that nickel electrodeposition from chloride media containing 90 g/dm3 Ni started with the generation of hydrogen bubbles, entirely blocking the cathode surface. Only a slight current development was observed until the polarization potential ~ -0,8 V. The visual observation showed bubbles also formed at the anode, which may represent chlorine and/or oxygen evolution. While, in the electrodeposition of nickel with only 1 g/dm3 Ni concentration in the electrolyte, metal deposition was hardly observed, but visible hydrogen bubbles constantly blocked the cathode surface. A similar tendency was observed in the mixed-solution electrolysis cell; the initial tiny bubbles accumulated at the cathode surface more than in the pure Zn solution. The enhancement of H2 evolution indicates how nickel deposition may contribute to the loss of useful current in the process of Zn electrodeposition. The mass of nickel deposited from the mixed solutions significantly decreases as the Ni concentration decreases in the electrolyte, while the mass of deposited zinc is relatively constant. It means that the purity of the produced Zn is appreciably higher – with respect to Ni – if nickel is efficiently eliminated from the solution before electrowinning.

A Literature Review: Artificial Intelligence Impact on the Recruitment Process
108-119Views:11393This paper aim is to review the implementation of artificial intelligence (AI) in the Human Resources Management (HRM) recruitment processes. A systematic review was adopted in which academic papers, magazine articles as well as high rated websites with related fields were checked. The findings of this study should contribute to the general understanding of the impact of AI on the HRM recruitment process. It was impossible to track and cover all topics related to the subject. However, the research methodology used seems to be reasonable and acceptable as it covers a good number of articles which are related to the core subject area. The results and findings were almost clear that using AI is advantages in the area of recruitment as technology can serve best in this area. Moreover, time, efforts, and boring daily tasks are transformed to be computerized which makes a good space for humans to focus on more important subjects related to boosting performance and development. Acquiring automation and cognitive insights as well as cognitive engagement in the recruitment process would make it possible for systems to work similarly to the human brain in terms of data analysis and the ability to build an effective systematic engagement to process the data in an unbiased, efficient and fast way.

Diagnostic Model for Supporting the Development of Health-conscious Organizational Behavior
1-18Views:329In the 21st century more and more countries of the world take the attitude that human health is not just an issue for healthcare services but for all major areas of life. Such an area for employees is the workplace. Protection of employee health and safety has for a long time been a non-transferable (objective) obligation and responsibility for employers in Europe. Connections between health and the workplace have however extended far beyond the traditional aspect of safety and health at work. Developing a health-conscious organisational behaviour means a challenge for many Hungarian companies; the model described in this study assists them in both diagnosing their current situation and choosing the appropriate course, method and tools for development.

Quality Development of a New Type Pharmaceutical Formulation
112-127Views:213The aims of companies to understand internal and external customer demands in order to improve their existing products and develop new ones. Product development aims at understanding customer demands that may influence the production of the product to be manufactured. As a first step in the process, the customer voice method was used to define demands with measurable parameters. A questionnaire survey was used to prioritise them, which were then compared and ranked using a preference matrix. Within the QFD method, technical parameters influencing the satisfaction of customer demands were determined. A correlation matrix was established and the relationship between the technical parameters was investigated. A competition analysis of technical parameters and customer demands was carried out. From the absolute and relative weights, it is easy to establish the order of the technical parameters, so that the most important parameter in terms of meeting the defined customer demands is the determination of the ratio of raw materials, and important parameters are chemical stability, pharmaceutical formulation and particle size.

Analysis of the Policy Background of Transport Related Use of Renewable Energy
124-129Views:100The EU energy policy prioritizes the following principles: sustainability, competitiveness and security of supply and addresses the reduction of greenhouse gas emissions as a priority. The related EU policy (including the White Paper on Transport) outlines these principles, identifies goals and opportunities for action. At company level methodological guidelines and standard procedures can be used to assess the carbon footprint of the organization, to generate efficiency goals and to prepare action plans. In the Hungarian policy framework, a comprehensive National Sustainable Development Framework Strategy defines the basic principles for the analysis of the sectorspecific or regional strategies. Sustainable Energy Action and Climate Plans (SECAPs) integrate energy and climate issues and include interventions and improvements for the better use of renewable energy sources in transport at municipal level. As a summary it can be stated that exploration of the policy background would needed to influence the use of renewable energy sources for transport and definition of the development goals can help economic organizations to transform their mobility patterns and reduce related carbon footprint.

The Relationship Between Renewable Energy Consumption, Net Energy Import, Greenhouse Gas Emission and Human Cap
58-71Views:161The measures to improve energy efficiency and increase of renewable energy production and consumption should be encouraged in the interest of sustainable development. Many factors can influence the use of renewable energy such as the level of economic development of an economy, nationals’ and the main economic actors’ environmental awareness, energy import dependency, ratio of the urban population, and government subsidization intensity among the others. The main purpose of this study is to examine the relationship between the share of renewable energy in the total energy consumption and net energy import as a percentage of energy use less production, greenhouse gas emission per capita and human capital using by OECD countries data from 1990 to 2014. The results indicate that there is a negative relationship between net energy import and renewable energy consumption, and also negative relationship can be shown between the amount of greenhouse gas emission per capita and renewable energy consumption. However, we identified a positive relationship between human capital and renewable energy consumption for energy importer countries above a certain level of human capital.

An Exploratory Study on the Level of Trust Among Hungarian Food Manufacturer Companies
277-288Views:217The intensification of globalized economic competition is playing an increasingly important role in the lives of companies to determine their true position among their competitors. Food companies are of paramount importance because of their role and weight in the national economy. In Hungary, the food industry plays an important social and economic role and is a world leader in terms of employment and value added. Currently, there are nearly 1100 active food companies in Hungary, so it is worth examining the peculiarities of the role of trust between companies.
There are often contradictory statements in the literature about the effects of Industry 4.0 technologies and the trust placed in IT tools. Therefore, it is a relevant research question to examine whether the characteristics of the role of trust - e.g. staff, suppliers, IT tools and technologies, etc. as confidence levels can have a direct positive impact on the efficiency, profits, liquidity, etc. of the companies in question. development.
During the research, I analyzed the level of trust between the food trading companies, in which I discuss the trust within the industry within the company. My aim is to further enrich my previous research knowledge in this field.

Proposition of Enhancing the Significance of Green Infrastructure in the Smart City Concept
1-22Views:219The aim of the paper is -in accordance with the goals of the research team called „ Sustainable Integrated Settlement And Regional Planning” within the project EFOP-3.6.1-16 – to compile a comprehensive expert material on smart city. In accordance with my personal assignments within the teamwork, I studied first of all how sustainable urban water management issues are managed in the corresponding smart city documents, how the smart city concept which is evidently one possible way of sustainable urban development involves the strategy of sustainable stormwater management along with the elements of green infrastructure which are the inevitable segment thereof. The basis of the study were Hungarian official methodological guides and one university textbook published so far in the topic. Contrarily to the expected results the two notions of smart city and sustainable urban water management are not harmonized despite their common overall goals. Therefore I make a few suggestions in order to harmonize to some extent the criteria and indicators developed for the two notions - smart city and sustainable urban water management including green infrastructure - promoting sustainable cities. The overall goal is to ensure that green infrastructure is not neglected while smart cities are realized.

Requirements for Multicultural Competencies Defined by a Focus Group
44-56Views:201Globalization, 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?

How Should We Develop the Careers of Our Employees? Organizational Career Management Tools in Focus
1-13Views:492We can observe more and more often that people change their jobs frequently. They work for more employers during their life. The question may arise that organizations should care about the career management of their workers? Certain surveys which investigate the reasons of job changes can disprove it. One of the most common causes is that employees cannot see their career opportunities at the company. The organizations should not necessarily use complex career development systems it may also be appropriate, if they use only some techniques consciously. The study shows the career management tools used by the organizations examined in the survey. The authors demonstrate that there is a provable relation between organizational performance and career development methods. Furthermore they describethe techniques applied by the successful organizations.

Food Industry 4.0 Readiness in Hungary
1-12Views:281In 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.

Artificial Intelligence Possibilities in Vehicle Industry
148-154Views:266There have been several attempts during the last decades to extend the ranges of application of artificial intelligence. The aim of the development for AI is to replace human intelligence and experience. The ultimate aim for machines and vehicles is to run much more efficiently and with higher reliability than ever before. The Artificial Techniques (AI) used a wide range of expert systems to optimize problems. Hybrid intelligent management systems have become increasingly influential in artificial intelligence during the last decades. As a result, maintenance and fleet management systems have undergone significant development. By choosing adequate maintenance or operating strategy and taking user behaviour into consideration, these systems can not only increase the reliability and efficiency of vehicles but can also result in financial savings. The paper tries to discusses the applications of AI techniques in predictive maintenance and vehicle industry.

Applying New Innovative Market Research Methods in the Innovation Process of New Products
56-69Views:212The innovation environment has changed a lot in the recent years, companies and their enterprises concentrating on product- and process innovation have undergone a lot of changes. According to GUPTA et al. (1986) product innovation is a multidisciplinary process. Although, all functional interfaces are important in the product development process, the research and development – marketing interface is one of the most difficult one. In the last two decades the incredibly fast penetration of the internet has more and more effects on the consumer attitudes. It encourages market researchers to apply such methods by which they could get as close as to the consumers to know their attitudes without taking them out of their natural habitat. In this study our aim is to concentrate on the first phase of the product innovation, which is the exploration of insights and attitudes. In this phase we can use the classical, conventional market research techniques if we want to get primary data, such as focus group interviews, questionnaires, in-depth interviews, but there are new methods as well. One of such novel methods is netnography. The biggest advantage of this research method is that the researcher can observe the consumer groups’ state of mind and decision-making mechanisms through publicly available communication sources in their natural environment. In this study it will be analysed how the directions of netnographic researches have changed by the dynamic changes of the internet. Besides, online participants’ attitudes towards healthconscious nutrition are analysed in practice. As a result of this study, special groups could be identified, which can provide a new perspective for the companies operating in this field beside the classical segmentation techniques. These groups can be the ones which draw up latent market requirements, and thus, helping the companies’ innovation processes.

Importance of quality indicators in the healthcare – in case of musculoskeletal rehabilitation –
1-11Views:148Nowadays the term of management is so popular. It has an essential role in the professional life, moreover in the every day life too. Creating and using the quality indicators (one of the qualiy management tools) contribute to the improvement of the operation of the healthcare system and to the development of the quality of healthcare services. The aim of the paper is to define service quality and its dimensions in healthcare and to highlight the role of quality indicators. The research calls attention to the absence of indicators measuring the different aspects of quality directly, the difficulties of measuring service quality and the need of establishment of more specific measures in healthcare. A special area of healthcare, there habilitation of musculo skeletal diseases will be discussed. As a research my approach is to define all the indicators that are already used in this area of the healthcare. This examination is extremely important because one of the most commonailments are the musculo skeletal diseases and their number is just increasing.The paper is mostly descriptiv and follows analitical methods based on the international and Hungarian professional studies, informations. To access databases I was helped by the OSAP (National Statistical Data CollectionProgramme). Besides the importance of quality indicators the research calls for the need for more specific measures. On the other hand, the value of the paper lies in collecting the problems, defaults and improving areas of a specific healthcare field.

382-391Views:127Entrepreneurship brings enormous benefits. It generates employment and helps in social and economic development. Ventures created through the youth entrepreneurship have enormous benefits. They generate employment, reduce poverty and unequitable distribution of wealth. These ventures do also help in social, economic and technological development. However, the youth faces several barriers to entrepreneurship. This study explores the personal & psychological, family related, institutional & regulatory, cultural & social, financial and market & knowledge barriers faced by the youth of Hungary and Pakistan. Qualitative research methodology was applied. Interviews at micro and meso levels were conducted from the young entrepreneurs and university professors of Pakistan and Hungary. Results indicate that Pakistan and Hungary have almost similar levels of Personal & Psychological barriers, however, the fear of failure is higher in Hungary than in Pakistan. Family related, cultural & social and market & knowledge barriers are higher in Pakistan for the youth entrepreneurship than Hungary. Institutional & regulatory and financial barriers are at medium levels in Pakistan. For Hungary, these are at low levels. The study has important implications for researchers, academicians, policy makers and for the young aspiring entrepreneurs.

An Overview of the Situation of SMEs in Hungary in Catching up to Industry 4.0
72-80Views:126Since I have been working I have been in contact with small and medium-sized enterprises (SMEs) and large companies in various ways. I have thus been confronted with the disadvantages of the former in terms of the introduction and use of 4IF technologies. Yet most of them are aware that to remain competitive in the market, they cannot avoid digitising their operational processes to some extent. I have also found that this mainly depends on the characteristics of the organisation; for example, its orientation. Domestic SMEs are therefore currently at a competitive disadvantage in the market. However, there is no information on whether there is a trend towards development and where they themselves should develop. This would help them to develop the right, achievable vision for the future, coupled with a feasible business strategy.
