Covid-19 Effects on the Environmental Practices in the Hotel Industry, Review Article and Managers\u27 Points of View
No full textCOVID-19 had its major effects on each aspect of life, that forced the humanity to modify and upgrade. It also showed that the harmful effects of human activities on the environment could be reduced and eliminated if they take serious steps. The effects of the hotel industry forced it to adopt green practices and upgrade them to reduce the negative effects of COVID-19 on the industry and even gain some competitive advantages and profits. This paper aims to analyze the positive/negative effects of COVID-19 on green practices within the hotel industry, in order to generate some useful lessons for the future or coming crises. This study depended on a mixed method to analyze this issue, a systematic review technique to analyze the scientific productions in this area, and then conduct interviews with managerial in green hotels to combine results. A total of 50 articles were extracted from the “WoS” database and analyzed using three main analysis levels. This study revealed that: (i) COVID-19 had a positive effect on green practices including the hotel industry and also some negative effects, those effects had be summarized into six main groups; (ii) green practices were able to reduce the negative effects of COVID-19 on the hotel industry; (iii) green practices generated a competitive advantage even in the darkest time. (iiii) The upgrade and increase of green practices in the hotel industry continue even after the risk of COVID-19 declined.

The Challenges of the Production Planning Process in Hungary
No full textThe results of the research highlight that the automation of production planning can significantly increase the efficiency and competitiveness of enterprises. However, it is worth every manufacturing company to clearly define which processes they automate, which processes are left to human resources. If human resources are used for certain activities, it is advisable to assign these tasks to appropriate job titles. Another important pillar of development is the accuracy of the information flow between production planning software and ERP systems. When designing new systems, it is essential to prioritise integration to ensure a smooth flow of data between systems. A critical aspect of production planning is assigning production orders to capacities. The condition for preparing an appropriate plan is the adaptation of products with different workloads and production equipment capacity to the norm. It is extremely important to take human capacity into account here. In a modern production planning system, such considerations must be seamlessly integrated. During the research, a fundamental need was identified for data visualization. Over the decades, many solutions have been developed to visualize production planning, offering opportunities to significantly streamline and improve planning processes. Another important element in increasing efficiency is the creation of the right ratio of flexibility and control, i.e. excessive control processes reduce the competitiveness of production. The main bottleneck in most developments and automation is the underdevelopment of IT systems in manufacturing companies. Intervention and support are needed here as soon as possible, as domestic manufacturing companies will only be effective if their IT systems are modern and competitive.The results of the research highlight that the automation of production planning can significantly increase the efficiency and competitiveness of enterprises.

Educational Methodological Issues in the Fields of National Security and Counter-Terrorism Higher Education
No full textAz oktatásmódszertan fejlődése a nemzetbiztonsági és terrorelhárítási felsőoktatási képzésekben jelentős változásokon ment keresztül az elmúlt évtizedekben. A 20. században ezek a képzési területek jellemzően zárt, a nyilvánosságtól elzárt módszereket alkalmaztak, míg napjainkra egyre inkább nyitott, multidiszciplináris megközelítéseket integráló rendszerekké váltak. A tanulmány célja az, hogy bemutassa azokat az oktatásmódszertani elemeket, amelyek segítik a hallgatók sajátos kompetenciáinak fejlesztését a nemzetbiztonság és terrorelhárítás területén. A biztonsággal foglalkozó tudományok különböző megközelítései multidiszciplináris területekként jelennek meg, amelyek magukban foglalják a társadalomtudományok, hadtudományok, rendészettudományok, valamint a műszaki tudományok elemeit is. A magyar felsőoktatási rendszerben a nemzetbiztonsági és terrorelhárítási képzések kizárólag a Nemzeti Közszolgálati Egyetemen elérhetők, ahol a képzések számos egyedi jellemzővel rendelkeznek. A nemzetközi példák elemzése is hozzájárult a hazai gyakorlat fejlesztéséhez. Az oktatás során fontos szerepet kapnak a kreatív megoldások, a hagyományos és elektronikus/online környezetek integrálása, valamint a gyakorlatközpontúság, amelyek jelen tanulmányban kerülnek bemutatásra. Továbbá ismertetjük az elmúlt években a hallgatók körében végzett kérdőíves felmérések eredményeit az oktatási módszerek vonatkozásban. Az oktatásmódszertan fejlesztése érdekében folyamatosan keresünk új megoldásokat, amelyek segítik a hallgatók kompetenciáinak bővítését, figyelembe véve a szakterületek igényeit. Az interdiszciplináris megközelítés, a gyakorlatközpontúság, a modern technológiai ismeretek, valamint az etikai és jogi elemek mind fontosak a hallgatók számára, hogy a megszerzett tudást a szektoron belül és kívül is hasznosítani tudják.The development of educational methodology in higher education courses in national security and counter-terrorism has achieved significant changes in recent decades. In the 20th century, these fields typically used closed methods not accessible to the public, whereas today they have increasingly become open systems integrating multidisciplinary approaches. The aim of this study is to present the methodological elements that help students to develop their specific competences in the field of national security and counter-terrorism. In the Hungarian higher education system, courses in national security and counter-terrorism are primarily offered at the Ludovika University of Public Service, where they have a number of unique features. Creative solutions, the integration of traditional and electronic/online environments, and a practice-oriented approach to teaching are highly important during the education of the field and they are presented in this paper. We are continuously seeking new solutions to improve educational methodologies (interdisciplinary approach, practice-oriented focus), expanding students\u27 competencies while addressing the needs of the respective fields
Spatial distribution of the 2022 “biblical-scale” drought in Békés County: Experiences of some farms in relation to the severe drought
No full textThe purpose of my research was to illustrate the spatial distribution of the 2022 “Biblical” national drought in Békés County. We found that 75 settlements in Békés County submitted 7288 reports. The data shows that settlements with larger populations also submitted more damage reports. We collected this to assist the work of the decision-makers whom are associated with rural development and rural economy research.
To collect the data needed to confirm my hypothesis, I conducted qualitative in-depth interviews with local farmers and analysed the spatial distribution of the drought with previously gathered area data and application data included in my analysis from the Hungarian agricultural Payment Agency and the so-called intermediate body, that is the Hungarian State Treasury and the Békés County Government Office that was provided by my co-author.
Both the interviews and the analysed data revealed that there were additional consequences and problems related to the great drought (continued lack of precipitation, the winters are milder even by modern standards, the rainy and dry periods became increasingly erratic and the soils capability to retain water has decreased). It should be noted, that all interview participants are either actively taking steps or have tried to implement methods and techniques that try to mitigate or reverse the harmful effects of such phenomena, with varying results. The human and economic factors still persist, and hamper their efforts to eliminate the existing and emerging problems, however there have been both negative and positive changes related to these issues.
I confirmed my hypothesis: the lingering after effects of the drought can be still felt and those farmers, whom live in the area are actively working to prevent further problems and repair these lasting damages, with varying degrees of success. We also learned that the drought’s impact was widespread but uneven, with certain settlements experiencing far greater agricultural losses. The spatial distribution of claims closely followed patterns of precipitation deficit and heat.The purpose of my research was to illustrate the spatial distribution of the 2022 “Biblical” national drought in Békés County.

Improving the profitability of small-scale dairy cattle farms by increasing the added value
No full textBased on the distribution of the cattle herd according to the specialization, the largest share is made up of dairy cows, their share is 77%. The economic difficulties of the dairy cattle sector and their solutions are not the same at the large-scale and small-scale farm levels. In this case, a small family farm dealing with dairy cattle is planned. During the calculation, the characteristics of small farms are considered, as well as the entire economic plan of the farm is set up, considering all expenses and income. From our calculations, it is shown how the various economic indicators develop in a three-person family farm. Increasing the added value clearly increases the profitability of the sector

Words in black and white? Experiments based on typographic signs and text usage in the grey zone of Hungary in the 1960s and 1970s
No full textJelen tanulmányom az 1960-as évek végétől az 1970-es évekig bezáróan az avantgárd törekvések újabb hullámának és az új médiumok művészetbe való beemelésének kísérleti megközelítéséből fakadóan, a tipográfia különböző megjelenési formáit vizsgálja. A betűk alkalmazása esetünkben nem a tipográfia funkcionális-tervezőgrafikai normarendszeréhez kapcsolódik elsődlegesen, hanem multidimenzionális megközelítésben, az autonóm művészet eszközeként vizsgálható. A nyelvi jeleken alapuló műalkotásokat a tipográfia formai és jelentést közvetítő funkciói alapján értelmezem, ahol a skála egyik végén formakísérletek, a másik végén szemiotikai dominancia áll. Vizsgálatom tárgya, hogy ezek milyen arányban vannak jelen a korszakban, valamint, hogy az új médiumok bevonása feszegeti-e a tipográfia további határait. Földrajzi viszonylatban elsősorban magyarországi eseményekre, alkotókra és alkotásokra fókuszálok, azonban helyet kapnak a magyar anyanyelvű „jugoszláv kollégák” is. Az, hogy a tanulmányban a szomszéd országokban élő magyar alkotók közül miért csak ők szerepelnek, arra vezethető vissza, hogy a munkáik úttörő megközelítése a tipográfia kísérleti jellegének tágabb értelmezését teszi lehetővé. A hazai progresszív művészeti eseményeken való aktív részvételük közvetlen kapcsolatot biztosított országunk magyar alkotóival. This paper explores the various forms of typography from the late 1960s to the 1970s, from an experimental approach to the new wave of avant-garde tendencies and the integration of new media into art. In our case, the use of letters is not primarily related to the functional-design graphic norms of typography, but can be examined in a multidimensional approach as an autonomous artistic tool. I interpret works of art based on linguistic signs according to the formal and meaning-conveying functions of typography, where form experiments are at one end of the scale and semiotic dominance is at the other. The subject of my study is the proportion in which these are present in the era and whether the involvement of new media pushes the further boundaries of typography. Geographically, the focus is primarily on events, artists and works from Hungary, but there is also a place for Hungarian-speaking “Yugoslavian colleagues”. The reason why only Hungarian artists living in neighboring countries are included in the study is that their pioneering approach to their work allows for a broader interpretation of the experimental nature of typography. In addition, they have been active participants in progressive art events in Hungary for many years and are thus directly connected to Hungarian artists in our country
Applying Analytic Hierarchy Process Methodology in Determining Critical Challenges of Urban Big Data in a Developing City: The Case of Tehran
No full textAlthough urban big data holds significant potential for transforming the way cities are managed, harnessing this potential requires overcoming major challenges, particularly in developing countries like Iran. Obstacles like policy gaps, legal barriers, limited resources for data management and infrastructure or even the low level of community engagement and the lack of technological capabilities could backward the development of becoming a real data-driven smart city. This study aims to address the understanding of this issue, by identifying and evaluating urban big data challenges critically, and to formulate policy-related support for governmental bodies in a country considered to be a developing information society. After thorough analysis of academic publications we identified 32 urban big data challenges in Iran, which then were systematically evaluated and ranked by Analytic Hierarchy Process (AHP) methodology based on expert surveys. Outcomes confirmed that although social, educational and financial challenges have been perceived, the most important ones are of political and governmental origin

A kutatás középpontjában egy új típusú, kereslethez igazodó integrációs modell áll, amely stabil értékesítési lehetőséget kínál a helyi mezőgazdasági termelők számára, miközben hozzájárul a költséghatékonyság és a fenntarthatóság célkitűzéseihez. A tanulmány alkalmazza a BATWOVE–keretrendszert az érintettek szerepeinek, motivációinak és akadályainak azonosítására, valamint a rendszer strukturális átalakításának megalapozására. A kutatás kvantitatív és kvalitatív módszerekkel vizsgálja a termelők integrációs hajlandóságát, valamint a fenntartható közbeszerzés gyakorlati megvalósíthatóságát. A tanulmány szakpolitikai és gyakorlatorientált javaslatokat fogalmaz meg a szabályozási környezet módosítására, a közbeszerzési gyakorlat átalakítására és a helyi élelmiszer–logisztikai rendszerek fejlesztésére, amelyek együttesen lehetővé teszik az adaptív, szinergikus és hosszú távon fenntartható börtönélelmezési modell kialakítását.The study examines the sustainability of food supply systems in correctional institutions through the lens of producer integration, with particular emphasis on economic, social, and environmental impacts. At the core of the research is a new type of demand–driven integration model that offers stable market opportunities for local agricultural producers while contributing to cost–efficiency and sustainability objectives. The study applies the BATWOVE framework to identify the roles, motivations, and obstacles of stakeholders, and to support the structural transformation of the system. Using both quantitative and qualitative methods, the research explores producers’ willingness to integrate and the practical feasibility of sustainable public procurement. The study proposes policy and practice–oriented recommendations, including regulatory adjustments, procurement reform, and the development of local food logistics systems, all of which contribute to the establishment of an adaptive, synergistic, and long–term sustainable prison food supply model
Módosított PV-T és hagyományos PV panel összehasonlítása statisztikai módszer segítségével, különböző áramlási sebességek esetén
No full textThis study explores how well a modified photovoltaic (PV) panel with a water-based cooling system performs under various environmental conditions. We compared a standard PV panel to one enhanced with copper pipes and aluminium adhesive, testing two different flow rates (4 l/min and 7 l/min) to see how solar irradiance and ambient temperature affect the working temperature. Our findings revealed that lower flow rates made the panel more sensitive to environmental changes, with solar irradiance and ambient temperature accounting for up to 92.5% and 80.2% of the temperature variation, respectively. The ANCOVA analysis confirmed that flow rate, solar irradiance, and ambient temperature all significantly influence the working temperature, with flow rate having the strongest impact. The results also showed a significant interaction between flow rate and irradiance, indicating that cooling effectiveness changes with sunlight intensity. However, the interaction between flow rate and ambient temperature was not significant, suggesting that the effect of flow rate remains consistent across different air temperatures.Ez a tanulmány azt vizsgálja, hogy egy módosított fotovoltaikus (PV) panel - víz alapú hűtőrendszerrel - hogyan teljesít különböző környezeti feltételek mellett. Összehasonlítottunk egy standard és egy rézcsövekkel és alumínium ragasztóval kiegészített napelemet, két különböző áramlási sebesség (4 l/perc és 7 l/perc) esetén. Megvizsgáltuk, hogyan befolyásolja a napsugárzás és a környezeti hőmérséklet az üzemi hőmérsékletet. Eredményeink azt mutatták, hogy az alacsonyabb áramlási sebesség érzékenyebbé teszi a panelt a környezeti változásokra, mert a napsugárzás és a környezeti hőmérséklet az üzemi hőmérséklet változás akár 92,5%-át, illetve 80,2%-át is befolyásolhatja. Az ANCOVA analízis megerősítette, hogy az áramlási sebesség, a napsugárzás és a környezeti hőmérséklet mind jelentősen befolyásolja az üzemi hőmérsékletet, és ezek közül az áramlási sebességnek van a legerősebb hatása. Az eredmények azt is kimutatták, hogy az áramlási sebesség és a besugárzás között jelentős kölcsönhatás van, ami azt jelzi, hogy a hűtési hatékonyság a sugárzás intenzitásával változik. Az áramlási sebesség és a környezeti hőmérséklet közötti kölcsönhatás azonban nem volt szignifikáns, ami arra utal, hogy az áramlási sebesség hatása konzisztens marad a különböző levegő hőmérsékletek esetén
