    Information security (namely, confidentiality, integrity, and availability of business-related data) is an issue which companies attach increasing importance nowadays. This is, however, not a self-centred goal to achieve, but an (additional) means businesses use to work towards security in their overall operations. In addition to briefly presenting two case studies on information security practices, this paper offers a survey of terms and management practices linked with process security. Business continuity planning and risk management techniques - as outlined here in connection with information protection controls - may cover all business processes at any company.

    Food security is a fundamental but often neglected aspect of economic growth and sustainable development. This paper examines the effect of food security on productivity (GDP/capita) over time, while taking the income level of various countries into account. Dynamic panel regression analyses suggest that food security is positively related to productivity, but this effect is stronger in more developed countries. The study highlights the complexity of the economic problems faced by the least developed countries, where increasing the consumption and supply of food is insufficient for significantly increasing economic performance.

    Nowadays, in the world's energy production structure, fossil fuels dominate and at the same time cause a number of environmental problems. Comparing the use of conventional fossil fuels with geothermal energy, this kind of energy production is extremely beneficial, as there are no pollutants and a renewable energy source. Moreover, if we want to compare geothermal energy with other renewable energy sources (such as wind energy, solar energy, etc.), much of the benefits can also be attributed to geothermal energy becouse it is a stable energy source and the area requirement is low. Due to these extremely favorable properties, the study of the applicability of geothermal energy is gaining ground in renewable energy sources. In addition, it is well known that there are approximately 20 to 30 million abandoned oil wells in the world, plus sealed wells for other purposes, and the final number may be much larger. In the case of abandoned oil wells, the escaping residual oil may be a problem, which can lead to significant environmental problems. Taking these factors into account, research on the recyclability of abandoned wells for geothermal purposes becomes a target for more and more research topics around the world. It is interesting to note that a significant part of the publications are concerned with examining the technological potential of energy utilization, studying heat transport processes, and generating general, energetic or economical evaluations. A publication of a kind that would have evaluated the safety of recyclable abandoned wells in publishing databases was limited. It is therefore an important question that the abandoned wells, from the point of view of human security and environmental protection. How can they be reactive, how can the new technological elements be built up and how much human security factors of the newly created system are affected by the existing elements?

    Mankind faces major challenges in the area of food safety and food security. In addition to the growing population, urbanization, climate change, global environmental change and economic inequality, as well as instability, have a major impact on balanced food supply. According to the WHO (2018) study, not only the elimination of hunger is a problem, but also the increase of our well-being. While 0.8 billion people suffer from a lack of available food, 33% of the global population is overweight, 30% of them are obese. In a long term our growing well-being can also be a great problem. There are three types of dietary problems that coexist in parallel: the hunger and malnutrition, the microelement deficiency, and excessive nutrition and obesity. These three health problems represent a serious burden on public health, which has to be considered in the context of food security and food safety.

  • Future Power Plant Portfolio Analysis from the Point of View of Minimum Cost and Emission Optimization

    The article examines the expected composition of the power plant portfolio in Hungary by 2030. The indicators considered are the life-cycle unit costs (LCOE) and the life-cycle specific carbon dioxide emissions (LCA(CO2)) of the power plant types. The minimum of these two indicators, as objective functions, is determined by a linear programming method for the power plant portfolio. The results show that the LCOE minimum for the power plant portfolios in 2030 is worse in absolute terms and better in specific terms than in 2021. In both absolute and specific terms, the LCA(CO2) minimum is more favourable in 2021. These results are met under the thirty and twenty-five percent electricity import scenarios. With twenty percent imports, the absolute values are worse and the specific values are better for both indicators. On the other hand, the results of the calculations for 2030 fall short of the 2030 Agenda of the Institute for a Green Transition. This is due to the delay in commissioning a new nuclear power plant and the transformation of industry with increasing electricity demand. For the portfolios under review, a minimum of thirty percent of domestic generation from renewable sources is met. This contributes significantly to the European Union's ambition for the sector to be net greenhouse gas-free by 2050.

    Most of the people assume modern slavery end up in 19th century. However, according to the International Labor Organization (ILO), today 40 million people live as a slave. Moreover, modern slavery is the world’s fastest growing crime and has huge number, which never occurred in history before. One of the main limitation of the existing literature on contemporary slavery is that it ignores the history of slavery either entirely or alternatively between past and present. However, this article aims to figure out the role of modern slavery, also recommends some suggestions to governments to solve the problem of it. The aim of this paper is to addressing to the modern slavery policies in a conceptual perspective. In the theoretical framework of modern slavery, rational choice theory, conflict theory and human security theory have been selected to describe the sequence of modern slavery.

    Over the past 25 years, many renowned scientists from a number of research institutes have developed a new research method, a new family of methodologies which is the MFA (Material Flow Analysis). The importance of MFA is given by the extent of excited material flows created by mankind. The basis of MFA's growing success is a radically new, interdisciplinary vision that requires collaboration between the natural and social sciences (ecology, thermodynamics, and economics), not only as an effective tool for examining material efficiency of production and environmental pressures, as well as the security of supply of the strategic material requirements of the system under investigation. In our article, we conduct an enterprise level analysis of the input and output side material flows and materials of a service company in Debrecen for 2018 using the MFA method. MFA indicators capture environmental pressures in a natural dimension, that is, in terms of mass, energy, or land, respectively, in terms of kilograms or tons, of the company's raw materials and their changes, or material inputs.

    The financial condition of families living on wages is function of many factors. It is determined, among other things, by the development of wages, social benefits, tax rates and the amount of allowances that can be granted. The part of the tax system that affects the largest segment of individuals changes every year, and even during the year, reducing predictability. In recent years, discussions over the taxes have shown that the rate of personal income tax cannot be evaluated separately from the social security contribution rate. Gross average earnings - on the grounds of raising the minimum wage and the guaranteed minimum wage - have more than four-times in nearly 20 years. However the rate of growth is higher in the average net earnings due to changes in the tax system. Compulsory determined wages increased to almost six-times over the years under investigated. But in 20 years, how much has the income situation of an average family living on a salary become more favourable or more unfavourable? In our study we are looking for an answer to how the increase in the minimum wage and the changes in the law how to have affected the livelihood.

This approach wishes to move towards sustainability, which deserves a significant role in nowadays through the world empathizing the negative effects of the wolrd. During my research I was looking for the answer that how the extended industry 4.0 and its tone be in Hungary via supply chain of the automotive industry. During my research I was looking for the answer that how the extended industry 4.0 be in Hungary and its tune through supply chain of the automotive industry. I also have examined that which changes are justified regarding management systems in interest of efficiency and emphasizing the human capital by leaders interviewed. As a part of qualitative research in-depth expert interviews were interpreted with help of content analysis based on the methodology of grounded theory. The results demonstrate the need to review and change existing processes in order to ensure that the potential of human capital is not lost and that technological development, even more so, is at the service of human resources in order to achieve its efficiency and effectiveness. Among the possible tools we can find the re-structurizing changes of post tracking processes of the audits in management systems providing quality. Furthermore, the practical implementation of multifactorial statistical process control in the evaluation of processed data, which may be one of the essences of industrial (IoT) data.

    The 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.

    Analysing the accident statistics, we can detact that, the improvement of the transport safety is one of the most important engineering task. The number of the vehicles in the trasport gets significantly higher from year-to year, and the infrastructure of the cities frequently can not coordinate already it. Therefore the increasing of the vehicles’s number naturally involves the upgrowth of the accidents occasions too. The aim of the improvement of the vehicle-construction to reduce the personal injured and death resulted accidents number in contrast with the increasing traffic performance. This study analyses the construction options for reducing the effect of the rear-end collision whiches are concentrated for the passive vehicles and its passengers firtsly.  Among the actual car manufacturers applied solutions, foward-looking possibilities and suggestions are described in this publication. The development can not be concentrated for only the safety improvement, the mass-optimalization must be completed simultenously. These apparent contrary requirements can be completed with application of new materials. Therefore the study addresses the more optimal utilization of the meatl foam in the vehicles crushbox. In addition, an optimized break-assist solution is described based on the Mercedes developed Pre Safe Plus® system to increas the abrorbtion of the impact energy.

    Projects are key drivers of organizational change, both their failure and success can have significant impact on the organizational performance. Risks may arise throughout the entire project life cycle. Managing these and initial project planning uncertainties is an important task of Project Management. The study describes the application of traditional project management tools and methods in risk analysis, -evaluation and -treatment based on modern project and risk management standards and recommendations. The authors also examine the link between classic project management objectives (project time - resources – scopes) and risk-based decision-making. The different scale and scope of projects call for different responses to the associated risks. The study highlights the possible role of the ISO 31000 risk management standard package in project risk management. The authors analyse the risk management of the different projects on the basis of processing relevant literature, including the relationship of the project stakeholders to the risks. R&D, agile projects and project portfolios have specific and complex risk exposures, but their project management can provide several „hidden” risk analysis and - treatment functions.

    Abstract. Theoretical background of enterprise risk management can be considered as founded by the ISO 31000 standard family and the COSO recommendation. However, their application in a given company domain requires knowledge of the local environment, and professional experience. Nowadays risk management is still anchored to functional fields, or organisational units (logistics, finance, quality management, HR, IT, e.g.). According to the view of the authors, this approach could results in parallel, multiple regulations of risk management. This could be avoided by a holistic view, and a risk based analysis of company processes. Writing this study is aimed at three
    major goals:
    - providing an overview of the bases of process and risk management,
    - proposing a professional idea to be used at risk management of processes (Is it possible to reduce business
    risk by analysing availability of resources assigned to processes?),
    - providing a review of standards and recommendations which can be used in process risk management.

    The utilization of renewable energy sources spread with stormy speed on the world therefore more and more municipalities propose that they satisfy their energy demand from renewable sources. The fossil fuels represent a significant proportion in Hungarian energy balance and the majority of these is import energy. The proportion of renewable energy sources must be increased to decrease the energy dependence and the energy cost of municipalities, to increase the energy security and to consider the aspects of environment.The interest of Hungary is to increase the proportion of renewable energy sources in energy supply. In order  to this, the government created the small-scale household power plant (SSHPP) category in the Electricity law. This power plants should be not greater than 50 kW's performance. In this category, electricity can be produced from renewable and fossil sources. Since the government introduced the small, household size power plant category the installed capacity was grown quickly in the last seven years. The general capacity was 0.51 MW altogether at the end of year 2008 but it has already approached 129 MW’s at the end of year 2015. The general capacity was increased by the multiple of the previous year every year between 2008 and 2015 and there will be more a dynamic capacity expansion. Data about the capacity and the produced electricity can be displayed on municipality level, too. The purpose of the investigations is to determine: how can the built capacity of the small, household size power plant category participates in the electricity supply of the Hungarian settlements? So how many percentages of electricity demand can be gratified by this electricity power on the settlements? Based on this a ranking can be made among municipalities which shows the level of sufficiency in production of renewable energy and give a possibility for the power shift. Finally, to what extent can be built upon this power plant category in order to that Hungary can comply its objective value.

    Today we cannot imagine our everyday lives without using our smart devices. While commuting we often get into people - even literally - who are doing their work on their portable devices 24 hours a day. This habit is widespread; there are many solutions that can be used by the corporation to have their employees work on their private devices, besides using it in their personal life. They can use these devices at their home, while commuting, or even while being at their own cubicle at the firm. In this article, we are concentrating on the IT risks of the firm with this work practice from a theoretical point of view. After this step, we will continue our research with investigating the problem of measuring and mitigating of these risks.
