Published: May 2020

In 1988-1989 a stream of East Germans sought refugee in Hungary at the Embassy of West Germany in Budapest. The three countries taking part in the issue made different solutions to deal with the increasing problem. The East German leadership tried to call back the refugees and calm down the emigration process, but it had lost its confidence. West Germany tried to solve the problem not only on the level of consulship but exten-sively, in part with recognizing the status those waiting for West German citizenship and those for refugee status - without any success. In the interest of the resolution and bring the Hungarian leadership to their point of view, they tried to make use of the international organizations. However, the Hungarian leadership made efforts to stay out of the issue to get the two German states make an agreement. But there was no chance for that so Buda-pest gave up its quasi neutrality and tried to solve the problem opening the border by avoiding Hungary to turn into a refugee camp of the region. Besides making this ad hoc arrangement, the whole issue needed more radical crisis management, not only in Hungary.

We have been looking for the possibility to build a computer model of costly gas utilization in the course of heat treatment of canned meat. This was necessary for us, as the first part of our long-term research, to be able to accomplish minimized costs by synchro-nizing heat treatment processes running side by side and by production programming to define completion time of the cans. First, because of our multiple data (paper based, text file, image file, Excel file), we have arranged them under a common user interface, while defining the best one from the data with different precision appearing in several sources. Based on the accurate data we did correlation and regression analysis to define the data influencing the gas consumption and to see whether our present data was enough to develop a model. Since the furnace has to ensure the steam supply of the heat treatment equipment and the heating of the buildings too, we defined the gas consumption of the furnace which is dependent on the environmental temperature.

The heat treatment of cans, particularly canned meat, is a process with a big energy need. The reduction of the use of the natural resources is the challenge in our days which appears in the new system approach of the environment management, the principle of sustainable development. That is to say, let us produce the same amount of products with less energy consumption, or more amounts with less specific energy consumption. We have to secure the observance of the regulations obtained this way for the sake of the higher quality and the less resource utilization with the use of engineering calculations, modelling and computer simulation. This observance ability is answered with the help of our developed database and model for the computer simulation of heat treatment processes.

This paper describes the implementation and configuration of the remote control and wireless sensor network using the Sun SPOT platform. As it is well known, greenhouses have a very extensive surface where the climate conditions can vary at the different points. In the last years, remote control and WSNs are becoming an important solution to this problem. Additional advantages of remote control are the possibility of control and monitoring these applications from remote places and having a system that can provide large amounts of data about those applications for longer periods of time. This large amount of data availability usually allows for new discoveries and further improvements.

A határon átnyúló agglomerációk turizmusának típusai
Authors: Székely Andrea
Published: May 2020

The new borders of Hungary in 1920 cut cities and agglomerations inducing their fallback, but the new situation favoured the creation of new functional centers. The closed boundaries after World War II resulted the development of spatial structures inside the national borders. At the same time, in Western Europe border urban areas organic development started, and they shaped cross-border agglomerations. The soundest example is the French-Belgian Lille cross-border metropolis. After the political changes, the cross-border cooperation based on real common socio-economic interest has become possible in Hungary. This processus is encouraged by the EU through its regional (Interreg, Espon) and urban (Urban, Urbact) programs. The analysis of cross-border agglomerations may be one of the axes of the Hungarian regional researches in the near future.

Crop production (including that of field crops, vegetables, fruits, grapes, medicinal plants and herbs) constitutes the basis of food supply and food industry and its economic interest is to main tain and expand the biodiversity of cultivated plants to meet the dem and of the market and production technology. The globalization, the EU-membership, the immigration and the tourism trigger the incessant broadening of the assortment of cultivated plant species and varieties. The most reliable and efficienttool to maintain and develop the biological base of our cultivated plants is to sustain and enhance the domestic plant breeding. It is the domestic plant breeding through which plant varieties best adapted to the domestic land and climate and the demand of growers, users and consumers can be created. Based on the National List of Varieties 2010, the study reviews the breeding results of the cultivated plants at the state-owned research institutes. It delineates the major problems  of the breeding institutes and outlines the potential solutions of these problems as well.

Presence of the international companies, alien properties, and the foreign capital in Hungary is under a wide social debate. It is the foreign capital which established Hungary’s long-range development and this capital will significantly influence it in the future, too. After the political transformation reintegration into the world economy, establishment of market economy and modernization of the economic structure realized by foreign investments implied an outstanding potential for further development. However, by today the capital drawing ability of Eastern Europe, and Hungary has declined as a result of which adaption to the new situation, reversal of this trend, our ability to keep the capital, and giving the chance to companies in home property all are of stressed importance. I could conclude that it is absolutely necessary to improve the capital attracting ability of Hungary from the aspect of her future developm ent. It is necessary to become specialized in new fields, in activities which need labour force of high qualification, for example we can aim at location of service, financial and adm inistrative centres within the company groups to our country. It is important to increase the efficiency of subventions. Besides, it is advisable to pay attention to regional development if we want prevent companies from leaving our country after that the subventions have been finished. We should pay more attention to the soft factors  f capital attraction. It is necessary to consider what qualitative and quantitative conditions a given area has for example, in the fields of life quality, education and culture.

In East Central Europe, and especially in Hungary, the increasing importance of the Medicinal and Thermal sector of Spa Tourism is beyond dispute. The selected basis for our research is South Transdanubia. This Region has truly outstanding natural potential in the sector, but the results of investment and development over recent years have not matched expectations. An analysis of statistical data revealed a gradual decrease in demand and the resulting falling behind of the region. Within the framework of our empirical research to date a total of ten spas (both medicinal and thermal) in Southern Transdanubia have been surveyed, in an attempt to identify reasons why visitors are staying away from the region. These embraced a lack of quality accommodation, the absence of a unified concept for the regional development of the sector and also of 'co-opetition'. Finally, through the 'best practice' example of the Burgenland, an Austrian province with similar potential we have indicated further problems.

The paper presents a research conducted on the M6 motorway in the Southern Transdanubian region. The basis of the research is data of 2006-2010 provided by the Hungarian Central Statistical Office. In the analysis I compare these measures only to themselves, assuming that they are independent from the sizes and economic potential of other regions. According to the findings of the research, it can be stated, that small regions closer to the highway benefit more from their state then those which are remote from it. Despite this small regional differences cannot be clearly linked only to the M6 highway, economic differences also prevail. In order to extend regional effects of the highway combined transportation developments would be necessary (water, rail, flight), and also the connection to with other highways in the Balkan region.

Traditional Hungarian foods get successfully to consumers if these products are sold on a special market. In our research we set a hypothesis that the decisions, what traditional food consumers make, are based on imperfect information. Place of purchase is an influential factor. Based on this assumption we examined the followings in a questionnaire survey: Where do customers like to buy these products?, Is there an appropriate market for these products?, What are the attributes of this market?The basic aim of our research was to know how special quality single and differentiated products can stay safely on the market. Consumer segmentation seemed to be a good way to know this, but even some members of the same segment can have different purchase decisions. Personal life style determines this deviation. The subject of our research was to see how effective segmentation influences the dynamics of consumer product choice.

The goal of this article is to show my readers how important is to improve the public controlling function in order to achieve a conscious application of the modern economic methods in the public management area. The issue is that the financial resources of the state budget are limited; in this way we are able to compare the two existing sectors of this field identified as public and competitive sector. The comparison will demonstrate that there is an abundant need for the public sector to be more efficient and result oriented at all levels of the public finances. Basically, there are no or very limited use of holistic controlling activities in the public sector unlike in its competitive partner. What conclusion can be drawn from it? The answer is simple, „adaptation". The public sector needs to adopt more of the controlling function, methods and systems from the competitive sector. The results yield qualitative changes in the controlling field which include massive challenges and responibility for the next generation of the public controllers.

This study deals with the industrialisation of the largest market centre of the Southwest Transdanubian Region of Hungary. Nagykanizsa was an agrarian town for a long time; however, a quick increase in trade begun from the 1830s. The industry showed small plant traits. The industrialisation started in the 1880s in this region too. Newness was the mass producing mechanised manufacturing. The manufacturing came into existence in three ways. The first case was when the already existing small plants were developed to factories due to the good trading opportunities. In the second case traders and craftsmen established businesses based on local innovations; therefore, new industries were acclimatised. And the third case was the creation of corporations which presumed large amount of capital. Due to the development, the industry became the most important sector in the structure of the economy of the town before the World War I.

Innovation is not just a technology, but it is rather a comprehensive vision of what the future should look like and which requires changes in many ambits. Innovation is driven by people's needs, ambitions and dreams, and it is necessary that people at different positions in the society change the way they work and live. Innovation, as a result of human interactions, often fails because people do not understand each other, as they belong to different worlds which have their own languages and cultures. While innovation system-like thinking recognizes that the needs are a good mix of factors for innovation, it is hard to establish the perfect mix beforehand: innovation systems and policies need to be adaptive. We tried to bring this complex vision to our future. The actuality of the topic is provided by the fact that we are in the period of the development of digital industrial revolution, on the peak of the technology innovations, slowly resulting in the revolutions of the machines.

This study is about Rimóc, a Hungarian village with 1 800 residents, where the local economic development (LED) is a main ambition, because in the concept of demographic and employment relations Rimóc is considered an underprivileged settlement. The research was carried out by a 5 manned team, where using the method of deep interviews, short interviews and a focus group interview, made with the help of locals, revealed some difficulties. These are the lack of cooperation between the locals, ethnic problems, lack of assets and motivation, which are preventing the process of the LED. Overcoming these problems can become the key of the future and sustainable development of the settlements. Since Hungary has many villages which also try to reach the state of self-sufficiency, in the case of Rimóc the tendency is similar, where the municipality, mainly the mayor, of the village initiated the begining of such processes in food supply and power supply.

Examination of the load-efficiency graph of the boiler showed that gas fee which determines the direct expenses significantly can be reduced by 6% if the load is balanced. It is typical to the present practice that when different products of different load are made at the same time, it is not taken into consideration when the shifts are planned. Then, for example, instead of the average load of 50% per shift it is typical that even the average load of 30% and of 70% can be observed in the consecutive shifts. However, even within one shift great deviations can be experienced because the production is not scheduled. It can be seen from the results that the increase of the unbalanced feature of the load results in the growth of the loss. With smaller average loads, balancing the load is of a bigger importance since the relative loss can be even 6% then. Besides the load of 50%, which can be regarded as the annual average, almost the loss of 5% was experienced in the worst case.

A közpénz funkcióinak összegzésekor, szintetizálásakor erre is tekintettel voltam, és utaltam pár olyan jelenségre, amelyek kialakulhatnak a közösségi források megszerzésére irányuló törekvésekből.

Kutatásomban megvizsgáltam a közúti fuvarozás és szállítmányozás magyar gazdaságban elfoglalt helyét és annak jelentőségét, ismertetve a belföldi és nemzetközi áruszállításra vonatkozó szabályozásokat, azok fontosságát a hatékony szállítmányozás érdekében. Hangsúlyt kapnak a szállítmányozási tevékenység során jelentkező kihívások, amelyekkel csak megfelelő ismeretek birtokában képesek megbirkózni a fuvarszervező szakemberek. Megvizsgáltam az utóbbi években lezajló változásokat és az azokhoz való alkalmazkodás lehetőségeit, módjait. Elemeztem a 2013-ban bevezetett elektronikus útdíj hatásait az ágazatra, annak előnyeivel és nehézségeivel együtt.

A gyógyszertár/patika olyan egészségügyi intézmény, amely szolgáltató és kiskereskedelmi funkciókat lát el. A hazai jogi háttér szigorú előírásokat fogalmaz meg, illetve működésében nagyon fontos a minőségbiztosítás. A gyógyszertárakban, mint az üzleti világban általában, menedzser tervezi, szervezi, irányítja és ellenőrzi a folyamatokat. Kutatások rámutattak arra, hogy a női vezetők sikeresebbé tehetik az ilyen típusú vállalkozásokat. Logisztikai és minőségbiztosítási rendszereik befolyásolják a gyógyszertár versenyképességét, amennyiben helyesen tudják meghatározni piaci pozícióikat, versenyelőnyre tesznek szert. Feladataik megoldásához segítséget nyújt a logisztika, amely magában foglalja anyagok, személyek, az energia és az információk mozgását. Ehhez az alábbi négy tulajdonság (gyógyszerész szakma, QP -meghatalmazott személy, menedzser és nő) egy személyben kell, hogy együtt legyen. A tudástőke és az interperszonális kapcsolatok segítenek megoldani a felmerült problémákat.

Kutatásunk témája a pálinka előállítás terén a 2010-ben bevezetett jogszabályváltozások - előállítási jogosultság további engedményezése, jövedéki termékekre vonatkozó adójogszabályok változása - hatásainak vizsgálata a gyakorlatban. Kérdőíves vizsgálatot végeztünk a bérfőzetőkkel, hogyan vélekednek a meghozott rendeletekről, valamint mennyiben befolyásolta ez főzetői szokásukat. A primer kutatáshoz tartozik 5 interjú, amit a témában szakmailag jártasabb személyekkel készítettünk. A bér- és kereskedelmi fözdék üzemeltetői, illetve a magánfözők kifejtették véleményüket, és megosztották velünk az utóbbi 4 év tapasztalatait. A 43 hektoliterfok mértékig bevezetett 0 forintos adófizetési kötelezettség pozitív hatással volt a bérfőzésre. A magánfözés engedélyezése megosztotta a bérfőzetők véleményét, viszont a fözdék üzemeltetői rámutattak a bejelentési kötelezettség hiányára, ami negatív következményeket vonhat maga után.
A táplálkozás aktuális összefüggéseiről
Authors: Simonyi Péter
Published: May 2020

A cikk az élelmiszerfogyasztás, táplálkozás, egészség és a fenntarthatóság összefüggéseit vizsgálja. A fenntartható fejlődés (fenntarthatóság) vitatottsága ellenére az ENSZ szintjén tárgyalt, világszerte kutatott terület a létező és fenyegető globális problémák megoldása érdekében. A létszükségletet jelentő élelmiszer ellátás, a népesség élelemmel ellátása hosszú távon csak a fenntarthatóságnak megfelelő megoldással biztosítható. Az élelmiszerfogyasztásnak, az egészséges táplálkozásnak és a fenntarthatósági elvárásoknak egymásnak meg kell felelniük. Egyre bizonyosabb, hogy a történelmi múltban gyökerező táplálkozás ma is hatással van az egészséges étkezésre, azaz a - cikkben megismerhető - paleolit kori táplálkozás nem csak az ember fejlődésére, hanem a mai élelemfogyasztásra is hatással van. A megválaszolandó kérdés az, hogy ez az egészséges táplálkozás pozitív összefüggésben van-e a fenntarthatósággal?
A szövetkezések szerepe a mezőgazdaság zöldség és gyümölcs szektorában
Authors: Panyor Ágota

Hazánk jó ökológiai adottságokkal rendelkezik a zöldség- és gyümölcstermesztéshez, ám az ágazat jelen helyzetében a gazdák töredékesen tudják kihasználni a lehetőségeket. Problémát jelent a termesztett fajták sokfélesége és az elaprózódott birtokstruktúra, továbbá az élelmiszerkereskedelem koncentrációja révén a kistermelők kiszolgáltatott pozíciója más piaci szereplőkkel szemben. Fontos lenne, hogy a jövőben egyre több kistermelő legyen tagja valamely termelői szerveződésnek, melyeknek bővülésével nem csak a saját gazdaságok fejlődhetnének, hanem az egész zöldség- gyümölcs ágazat fejlesztését is elősegítenék.
Keszthely és környékének demográfiai elemzése 1990-2011 között statisztikai adatok alapján

Tanulmányunkban Keszthely és környékének demográfiai elemzését választottuk, elsősorban a szuburbanizációs és a dezurbanizációs folyamatok tükrében. Vizsgáltuk, hogy 1990 és 2011 között milyen demográfiai változások történtek, milyen mértékű volt a Keszthelyt körülvevő településekre való beköltözés. Elmondható, hogy a vizsgált időszakban számottevően csökkenő tendenciát mutat Keszthely népességszáma, míg egyes környező települések népessége szignifikánsan növekedett. E folyamatok jól illeszkednek a hazai szuburbanizációs trendekbe, ám mértékük a hasonló méretű városok környékén megfigyelthez képest sokkal jelentősebb.

With the emergence of Internet of Things (IoT) along with its development of advanced authentication, both security and remote monitoring have become imperative as well as essential, and the need for smarter security systems has only been growing. The traditional system needs an individual to use a key or an identiﬁcation (ID) card or a password to access the security doors. However, they have many limitations such as keys can be forged, recreation of ID cards and passwords can be stolen. To overcome, the existing system issues, a novel approach is proposed with the design and development of face authenticated web-based smart door lock control system using facial recognition and remotely monitoring the door. In this proposed system OpenCVs self-trained Haar Cascade Classifier along with Histogram of Gradient is used for face Recognition. Door will be unlocked when users face is recognised else will remain closed. In case an unauthorised person is found, the time of intrusion and the intruders image will be captured and sent to a separate server on discord, so that the user or the admin can view them at their convenience. The main usage of this system is to assist users for improvement of the door security of sensitive locations by using face recognition and is also designed by considering the physically challenged persons also.
SHRINKAGE OF VARIOUS TYPES OF PORTLAND CLINKER-BASED CEMENTS WITH RESPECT TO THEIR HYDRATION DEGREE
Authors: Davidová Vendula , Reiterman Pavel
Published: May 2020

The volume changes of cement based composites are significantly exhibited in the hardening process. Initial phases of the hardening are complemented by the expansion due to the heat evolution that is subsequently alternated by the shrinkage. Both could cause a crack initiation. It is evident that ultimate volume changes of cement based composites are a complex process, because the final shrinkage is determined by the binder used, exposition and also by the previous history. The paper focuses on the evaluation of the main types of cements based on the Portland clinker by using a conventional procedure for the determination of the shrinkage on the standard cements mortars. These mortars were exposed to drying after 1 and 3 days of curing, related to the actual degree of hydration, which was estimated on the basis of compressive strength development. The hydration process was additionally monitored using thermogravimetry on the accompanying paste specimens during one year. The performed experimental program confirmed the essential sense of the curing regime especially for blended cement systems, which exhibited very low values of the hydration degree at applied curing intervals. Despite the slightly higher values of shrinkage of blended cements, the obtained results signalize the crucial effect of prolonged curing for these types of binders. The conclusion highlighted the necessity of taking into consideration the hydration degree during cement testing by using the conventional contact method. Otherwise, the simple interpretation leads to an overestimation of the less-suitable material solution.

The study of the dynamic behaviour of non-uniform thickness circular plate resting on elastic foundations is very imperative in designing structural systems. This present research investigates the free vibration analysis of varying density and non-uniform thickness isotropic circular plates resting on Winkler and Pasternak foundations. The governing differential equation is analysed using the Galerkin method of weighted residuals. Linear and nonlinear case is considered, the surface radial and circumferential stresses are also determined. Thereafter, the accuracy and consistency of the analytical solutions obtained are ascertained by comparing the existing results available in pieces of literature and confirmed to be in a good harmony. Also, it is observed that very accurate results can be obtained with few computations. Issues relating to the singularity of circular plate governing equations are handled with ease. The analytical solutions obtained are used to determine the influence of elastic foundations, homogeneity and thickness variation on the dynamic behaviour of the circular plate, the effect of vibration on a free surface of the foundation as well as the influence of radial and circumferential stress on mode shapes of the circular plate considered. From the results, it is observed that a maximum of 8.1% percentage difference is obtained with the solutions obtained from other analytical methods. Furthermore, increasing the elastic foundation parameter increases the natural frequency. Extrema modal displacement occurs due to radial and circumferential stress. Natural frequency increases as the thickness of the circular plate increases, Conversely, a decrease in natural frequency is observed as the density varies. It is envisioned that; the present study will contribute to the existing knowledge of the classical theory of vibration.
NATM TUNNELS – CONSIDERATION OF THE PARTLY DAMAGED PRIMARY LINING IMPACT FOR THE SECONDARY LINING EVALUATION
Authors: Trunda Vlastislav , Hilar Matouš
Published: May 2020

Tunnels excavated by the New Austrian Tunnelling Method (NATM) are traditionally supported by a double-shell lining. The primary lining is generated from reinforced sprayed concrete with rockbolts, the secondary lining is generated from in-situ cast concrete and it is protected by a waterproof membrane. The static evaluation of the long term behaviour generally assumes full degradation of the primary lining (the primary lining impact is not considered). Some investigations of tunnels constructed in past indicated that the primary lining degradation is slower than expected. This paper discusses possibilities of partly damaged primary lining consideration in static calculations of the secondary lining. Various options were verified by numerical modelling, and its results were compared and discussed.
