Laboratory Testing of Rediffusion of Contaminants Using DKS-Permeameter
41-48Views:145Decades long hydrocarbon contaminations effecting heterogenous groundwater systems is a common problem both in Hungary and worldwide. Only the treatment of aquifer layers is possible with remediation technologies, so the contaminations remained in the aquitards are released back to the treated porous layer after the treatment due to the changes in concentration-gradient. This process is the so-called back-diffusion: as a result, the previously removed contaminations appear in the remediated layer again. In order to get better understanding of the rediffusion process and the influencing parameters series of measurements were carried out at the University of Miskolc Faculty of Earth Science and Engineering using a special laboratory device called DKS-permeameter. With the help of some small modifications it can be used for the modeling of backdiffusion. Artificially contaminated soil samples were built in the DKS-permeameter from which contaminanant release occured due to back-diffusion. The concentration values were determined with spectrophotometric measurements.

Price Analysis Practices in the Pig Sector
1-12Views:114The analysis of sales prices has become a particularly important topic in pig production research, including statistical analysis. With globalisation, we can say that today we are talking about a sector constantly exposed to the effects of the world market. It is also worth pointing out that, compared with other sectors, the impact of external regulation and influence is less pronounced. Thus, the aim of the present research was to identify the journal articles published on the subject of price analysis and, on the basis of these, to establish the correlation with the methodologies often used. It examines the spatial location of price analysis. The results obtained show that the practice of price analysis is mainly carried out in the context of market leading countries, usually on the basis of a cross product chain issue. The research shows the emergence in recent years of increasingly sophisticated methodologies that allow more accurate conclusions to be drawn, while also facilitating planning from a practical point of view.

New Research methods of Sales-Marketing Interfaces
160-183Views:379The energy invested in research in this topic is justified by the fact that the lack of optimal integration between SM (sales-marketing) can negatively affect overall corporate efficiency. The aim of this article is to present possible research methods that can reveal the impact of selected indicators, such as information exchange, coordination, vision and communication, conflicts, on the operation of the SM interface, according to Hungarian and foreign employees of international companies, and how they affect sales and marketing collaboration between pharmaceutical companies (PMC) and non-pharmaceutical companies (NPMC). It also attempts to demonstrate how the Partial Least Square (PLS) path modeling technique can provide valuable information on the consequences of management activity, and how the methods provided by Voyant Tools provide further research through quantitative analysis of qualitative data on the marketing sales interface (SMI), they can open up opportunities. The PLS-PM modeling technique was used to explore the relationships between the selected factors and possible hidden variables. These results clearly demonstrate that there are factors that influence SM collaboration that operate differently in PMCs and NPMCs, and that nationality differences can have a significant impact on how employees evaluate factors that affect SM collaboration. Of the methods we selected by Voyant Tools, the t-SNE (t-Distributed Stochastic Neighbour Embedding) tool proved to be the most sophisticated analysis, allowing the deepest analyzes by exploring relationships between groups of terms. -
Energy-Efficient Buildings, a step towards Sustainability in Pakistan
109-124Views:304With every passing year, energy consumption in the world is increasing drastically. Most of the energy comes from fossil fuels which are also depleting in a fast manner. Buildings consume a significant amount of energy all over the world and the demand for energy is also increasing unremittingly in buildings. Developed countries are taking profound measures in order to make buildings energy efficient and sustainable by achieving nearly zero energy stage. Pakistan is facing a serious energy crisis from the past few decades. The building sector in Pakistan deserves special attention in this regard since the energy consumption in buildings in Pakistan is feverishly high. Many types of research have been carried out in Pakistan by the United Nations and Energy Department of Pakistan in order to devise applicable methods that not only provide thermal comfort to the occupants but also make a building energy efficient. Renewable energy also plays an important role in compensating building energy demands. It is easy to achieve nearly zero energy state in a good energy efficient building if it is coupled with renewable energy sources then it will make it self-sufficient in energy demand. A survey is also carried out to determine the thermal comfort of the occupants in different types of areas. Also, solar energy analysis is also taken into account to highlight the solar power potential in Pakistan. Several recommendations have also been suggested to implement energy efficiency measures in Pakistan.

The Possible Job Creation and Job Destructive Effects of Technological Development
53-61Views:339Throughout history, technological change has often provided the basis for employee anxiety. Between 1811 and 1816, a group of workers in England who called themselves "Luddists" destroyed machines, because they thought it would endanger their workplace. 19th-century thinkers and economists such as Karl Marx and David Ricardo predicted that mechanizing the economy would ultimately worsen workers' conditions, depriving them of a decent wage. Over the last century, John M. Keynes (1930s) and Wassily Leontief (1950s) have expressed their fears that more and more workers will be replaced by machine solutions that will lead to unemployment. In recent years, Brynjolfsson and McAfee (2014) have argued that existing technologies reduce the demand for labor and put some of the human workforce at a permanent disadvantage. However, there are a number of compensation mechanisms that can offset the initial displacement effects of automation and process innovation in general (Vivarelli, 2015). First of all, while workers are being replaced in industries that introduce new machine technology, additional workers in new industries are needed. Second, automation (and process innovation in general) reduces average costs. Acemoglu and Restrepo (2017) found that this results, on the one hand, in the effect of price productivity (“priceproductivity”) (as production costs decrease, the industry can expand and increase labor demand); and, on the other hand, it leads to economies of scale in production (the reduction in costs due to automation leads to an increase in total output and increases the demand for labor in all industries). Similarly, Vivarelli (2015) argues that lower average costs can result in lower prices (if the industry's market structure is perfectly competitive), stimulate product demand, or result in extra profits (if the industry's structure is not perfectly competitive). If these extra profits are reinvested in the company, this investment can create new jobs. The presentation intends to present these counterbalancing cases and to provide real examples based on the literature.

Analysis of labor consumption in Hungary in the last 5 years
127-137Views:174The main idea of my research was the statement of the President of the Hungarian Fruit and Vegetable Interprofessional Organization and Product Council (Ferenc Apáti), according to which the main obstacle to the future development of horticulture and the development plans of horticultural enterprises is capital shortfall factors). The employment of seasonal workers in the production of grapes and fruit and in horticultural farms is of the greatest importance. As a result, in my research, I examined the use of labor by those working in agriculture over the past 5 years. I reviewed how the coronavirus has affected the time spent by seasonal workers at work in the recent past. Since there are a lot of work phases in agriculture where there is a temporary use of labor, I considered it important to get around this topic better. As seasonal agricultural workers are often able to reach their agricultural jobs through travel and border crossings, government regulations (travel restrictions, border closures) have made it more difficult for these people to access jobs.

A Selective Study: Camels Analysis of Indian Private Sector Banks
277-283Views:155Banking sector is one of the fastest growing sectors in India. Today’s banking sector becoming more complex. Evaluating Indian banking sector is not an easy task. There are so many factors, which need to be taken care while differentiating good banks from bad ones. Performance evaluation of the banking sector is an effective measure and indicator to check the soundness of economic activities of an economy. The contribution of RBI and other policy maker, the banking industry has witnessed regulatory requirements like BASEL III norms. These regulatory changes have influenced prominent improvement in efficiency and performance of the Indian Scheduled Commercial Banks in the past few years. In the present study an attempt was made to evaluate the performance & financial soundness of select Private Sector Banks like ICICI,HDFC AND YES bank using CAMEL approach from 2013 to 2017 as well one way anova method. It is observed that on an average ICICI was at the top most position. It is also observed that yes Bank was at the bottom most position in selected CAMEL ratios.

Challenges and Benefits of Working in Teams – Interpersonal Interactions in Health Care
11-19Views:306Teamwork has become the accepted way of doing one’s job. This is so true even profession’s that were considered an exception are shifting towards teamwork. Apart from the well-known benefits, there seems to be a downside of the enforcement of this work strategy. Conflicts, frictions, frustration in working groups can affect the dignity, psychological or physical integrity of team members, generally referred to as psychological harassment, workplace bullying or mobbing. The outcomes of the phenomenon are various negative organizational responses. Health care is somewhat lagging behind in this shift towards working in teams, but with increasing specialization greater coordination is needed between health care professionals. Above all, the patient wishes to be more involved in the health care process. Research suggests that patient involvement and working in teams have a positive impact on effectiveness and patient mortality, respectively. One of the challenges for health care is to include the patient in the teamwork process as an equal member of the group and at the same time overcome the drawbacks mentioned above, in a setting where a traditional, paternalistic approach is still present and the vulnerability of the patient (and his/her dignity) is evident.

An Exploratory Study on the Level of Trust Among Hungarian Food Manufacturer Companies
277-288Views:228The 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.

Innovative Utilization Possibilities of Industrial Wastes from Hungary as Construction Industrial Material
203-212Views:125The research results carried out at the University of Miskolc Faculty of Earth Science and Engineering in the Center of Excellence of Sustainable Natural Resource Management show that the physical and mechanical properties of the construction industrial products (strength, compactness) made of waste sources can be controlled reasonably by the appropriate processing technologies and under optimized circumstances and characteristics (particle size distribution, specific surface area). It was established that beside the chemical activation, the mechanical activation of solids is an effective tool for improving the product characteristics. However, this modifies the physical as well as structural, mineralogical properties of the raw materials, therefore its determination is of great importance.

Strategic Role of HR in Hungary and Slovakia, Based on the International Cranet Research (2015-2016)
478-489Views:328Western-European management trends have been spread including modern approaches to human resource management over the past decades in the countries of Central and Eastern Europe. The point of the new HR conception is the strategic partner role, which is underpinned by the appreciation of human resources. There was a rapid change in the management methods of the organizations due to the socio-economic changes in the examined countries. However, in many places the personnel departments were simply renamed, and their HR staff are still concentrating on their traditional activities. These activities are important and should be fulfilled today as well, but to play an influential role in the design and maintenance of organizational competitiveness HR should have a new, strategic attitude. The study examines HR's strategic role based on the empirical international Cranet research in Hungary and in Slovakia.

Construction of Tourism Supply Chains Based on Consumer and Service Provider Responses
Views:211The tour operator wants to satisfy all the needs of those who want to travel at the highest possible level. Experiences related to planning and organizing trips are almost as important as the vacation or excursion itself. My study compares the characteristics of domestic and foreign trips based on the consumers responses. The comparison was done by the following points: time for preparations, the reservation process, getting to the selected destination, the hotel selection, or the duration of the journey. At the same time, the chain is completed with tourism service providers, whose cooperation is key to meet the needs of travellers, all in the common interest of the guest being satisfied when they return home.

Employment Challenges in the Second Wave of the COVID-19 Virus from a Corporate Perspective
152-163Views:649The changed market conditions caused by the Covid-19 virus forced companies to rethink their strategy and structure and to optimize their processes. The aim of my research is to shed light on the changes in the second wave of the coronavirus epidemic that have had a significant impact on the operation of businesses and presented them with significant challenges. For the study, I used the results of a previous questionnaire survey (Pirohov-Tóth 2020; Pirohov-Tóth, Kiss 2021), which were supplemented with a literature analysis and statistical data from the database of the Central Statistical Office. Furthermore, compared to the first wave of the virus, I examined how job productivity changed in the second wave of the virus. Finally, corporate crisis management options have been presented in my analysis, the practical application of which can contribute to re-emerging from the crisis. It can be stated that the acceleration of digitization and the widespread expansion of advanced technological tools and methods can be considered as one of the biggest positives of the viral situation, which can also mean survival for companies in this pandemic situation.

Automated static structural FEA environment in MATLAB using Solid Edge and Femap
17-22Views:111Nowadays, CAD and FE software are getting integrated to each other. However, these new integrated pieces of software cannot be customized enough to analyze different optimization methods or model behavior. In this paper, a MATLAB environment is developed that connects to C# and VB programs, which use Solid Edge and Femap API functions, in order to automate the geometry modification and the FE model building and solving functions. A simple static structural size optimization problem is solved with the fmincon solver of MATLAB.

Global and Domestic Status and Prospects of Green Biomass Utilization
85-105Views:160Nowadays, the energy consumption of global population is depending on fossil fuels, but the role of renewable energies has been increasing rapidly, primarily due to the depletion of fossil fuels, the appreciation of environmental problems and climate policies. Biomass is the fourth most important energy resource in the world, provided an estimated 70% of global renewable energy supply. However, the annual growth rate of biomass is lagging behind modern renewable energy sources. The type of biomass is very diverse and can be processed and utilised by different methods. Currently, in the "green chemistry" industry (the replacement of petroleum-based, synthetic chemical raw materials with bio-based compounds from plant biomass), the importance of combustion, pyrolysis, biogas, bioethanol, biodiesel and basic chemical compounds production have been increasing. The objectives of the present research is to analyse the global and domestic status of renewable energies and biomass production, furthermore the possibilities of utilization of perennial, herbaceous biomass plant, the giant reed (Arundo donax L.), with which has been conducting research for numerous years at the University of Debrecen.

The Impact of Gas Flaring On Man and His Environment and the Way Out
82-90Views:167The nature of flaring processes has created a severe impact on man and the environment. Massive environmental degradation as a result of flaring activities has led to fluctuations in climate as well as depletion of the vegetation cover through acid rain. Findings have been made on some harmful gases released into the atmosphere that have effects on the environment and also on man. In order to control these effects by ensuring a clean atmosphere and environment, a new flaring model (DanMat flaring model) has been suggested. The model uses smoldering mechanism to reduce the amount of heat released into the atmosphere during conventional flaring by 60%. It also uses scavengers to oxidize harmful gas produced during flaring activities into less harmful ones. With this model one can flare gas without polluting the environment since it reduces the emissions of harmful gases during flaring.

Development Lies in Corporate Processes
358-369Views:254Nowadays, our rapidly evolving world is characterized by constant change. Organizations need to be prepared and responsive to these systematic changes to compete in the marketplace. Today nothing is constant or predictable because the organization is driven by the "3 C" force (customers, competition, change). Rapid adaptation to ever-changing circumstances requires companies to move from structured organizations based on traditional functions to process-based management. By using state-of-the-art process management procedures, organizations can be made transparent, analysable, measurable, and continually improving, and help companies increase their performance and organizational flexibility, and reduce costs. It also helps to recognize when it is necessary to change a process for an effect. In the event of creating well-organized processes, companies are more responsive to changes in the market, allowing them to operate more efficiently, and to carry out development activities easier. Nowadays, development as a new framework focuses primarily on digitalisation, which is challenging for companies to adapt but without this, they would be left behind in the competition. These challenges require radical changes and transformations in the lives of many organizations, which are difficult to achieve. With the development of process-based enterprise management, not just multinational companies can improve their operation, but small and medium-sized enterprises can also move towards digitalization thus inducing development for not only their own but for the economy as a whole.

Industry 4.0 Concept and Key Elements
100-111Views:266Growing and constantly changing international competition, increasing market volatility and demand for increasingly customised products (personalised manufacturing), and shorter product life cycles create significant challenges for companies that traditional production systems can no longer meet. Industry 4.0 is a new manufacturing paradigm focused on creating intelligent products and processes. The focus has been placed on achieving fully effective customised production under conditions suitable for mass production. Make-to-order replaces make-to-stock. Despite the growing interest in Industry 4.0, it is still not a consensual concept. There is no clear idea about this new manufacturing paradigm, so I attempt to present the available definitions of Industry 4.0 through the presentation of the scientific literature, declare the concept's technical elements, and present them in detail to get a clearer picture of the concept.
