Abstract:
Economic theory is required to develop a definite attitude toward free competition. The absolutization of this phenomenon leads to the entropy of the economic system (its death). However, full state regulation of economic life of society will lead to stagnation and degradation. Thus, the problem of determining the optimal ratio of chaos and order in the socio-economic system in order to increase the vitality of society becomes gnoseologically relevant.

Abstract:
This review discusses the present understanding of the inner region of AGN. Several fundamental questions are adressed, such as the determination of the central mass, the accretion rate and the presence or absence of massive accretion disks. The “standard model”, used until recently to deduce the density, ionization, geometry and other physical properties of AGN, is facing sever difficulties and several unsolved problems, such as the hydrogen line ratio, the FeII spectrum, the energy budget discrepency and the confinement of the broad line clouds may force us to abandon it all together. The new line-continuum reverberation measurements are perhaps the most important developement of recent years and their significance is discussed in relation to the other mentioned problems. Thin or thick accretion disks are likely to be present in the very center of AGNs. The theory of such disks is not advanced enough to provide accurate spectral calculations and the best way to identify them is to look for the signature of their nonisotropic radiation field in well selected samples. Several new developements and ideas, such as disk shaped emission line region, stars and stellar winds as broad line clouds, dust emission and very small-very dense BLR are also discussed.

Abstract:
The paper examines applicability of Inglehart?s model of dimensions of traditional/secular-rational values and survival/self expresion values, based on European Values Study data, conducted in Serbia in 2008. Dimensions of values are extracted by applying nonlinear principal component analysis, with asigning ordinal level of analysis. We present three-dimensional solution which separates dimension of survival/self expresion values into two dimensions. The deviations from the two-dimensional model were interpreted in accordance with the theory of revised modernization and thesis about value change in dependance of sociocultural paths of developement of society.

AbstractThis paper investigates the impact of human and political capitals of entrepreneurs on enterprise performance in four emerging nations.The rent generation potential of these capitals is a well established fact, however, much less is known concerning the contingent nature of their value creation prowess. In this work, we draw on institutional theory and dynamic managerial capabilities perspective to examine the interactive effect of country of origin economic developement level and the international experience of entrepreurs, on the capitals, with respect to a set of financial indicators. Employing a quantitative methodology, our findings reveal that the relationship between the capitals and enterprise performance are indeeed contingent with the capitals of home-grown entrepreneurs, rather than those of returnee migrant entrepreneurs, exhibiting a greater propensity to influence enterprise performance. We conclude with implications for theory and practice.

Abstract:
A solid-supercritical fluid system is highly asymmetric in terms of the size and energy differences of the components. The key point in extending a cubic equation of state to such system is on the choice of proper mixing rules. New mixing rules for the Redlich-Kwong equation of state are developed. The developement is based on the statistical-mechanical theory of the van der Waals mixing rules. The Redlich Kwong equation of state with the proposed mixing rules along with the original ones is used to predict solubilities of solids in supercritical fluid. The prediction is done with kij equal zero, as well as with optimized kij. The results show superiority of the proposed mixing rules over the original ones. For most of the systems considered, the proposed mixing rules with the kij equal zero are closer to the experimental data than the original ones do. For 28 systems with 521 data points taken from various sources, the original and the proposed mixing rules give the overall AAD of 13.4%, while the original mixing rules give 45.9%.

Abstract:

Denna undersökning bygger på lärares attityder till konfliktsituationer och deras föreställningar om hur de agerar vid dessa. Det vi i vår undersökning eftersöker är dels om lärarnas agerande skiljer sig mellan år 1 och år 6 och dels om deras utsagor tyder på en bakomliggande teoretisk kunskap. Med hjälp av en kvalitativ ansats görs åtta intervjuer med behöriga lärare, fyra verksamma i år 1 och fyra verksamma i år 6. Analysen av det insamlade materialet visar att varje lärare har skilda sätt att se på konflikter och majoriteten anser att de både har positiva och negativa aspekter. När det gäller sättet att hantera konflikter har vi funnit att en gemensam grundmodell används. Dock har alla lärare sina egna konflikthanteringsstrategier som de använder beroende på situation och ålder på barnen. Trots att lärarna säger sig ha ytterst lite utbildningen om konflikter och konflikthantering tyder deras utsagor på en bakomliggande teoretisk kunskap.

Abstract:
Med ett förändrat klimat förväntas nederbörd och kraftiga skyfall öka i framtiden. Detta i kombination med en ökad urbanisering och allt fler hårdgjorda ytor i städerna leder till att befintliga dagvattensystem kommer bli överbelastade. Nederbörden förväntas öka med 10-20 procent och avrinningen med 5-25 procent under det närmaste seklet. I många städer har de naturliga avrinningsområdena försvunnit i samband med urbaniseringen och bostäder byggs på olämpliga platser med stor översvämningsrisk. Behovet av en hållbar dagvattenhantering är betydande för att undvika negativa konsekvenser i städerna framöver. Den traditionella dagvattenhantering med rörsystem blir alltmer kritiserad för att vara ohållbar. I Malmö är dagvattenfrågan högst aktuell då staden nyligen blivit drabbad av översvämningar. Studiens fokus ligger på vilken syn större fastighetsägare och VA-huvudmannen har på dagvattenhantering i ett förändrat klimat. Studien är av både kvalitativ och kvantitativ karaktär och består av två intervjuer samt en kompletterande enkätundersökning. De slutsatser som framkommit av studien är följande: Det behövs ett ökat samarbete med skyfallsproblematiken i Malmö, förändring av lagstiftningen för tydligare ansvarsförhållanden, fastställa finansieringen av åtgärder, arbeta mer mot öppna lösningar och minska fokus på ledningsnätet, öka kunskapen hos stadsplanerare och fastighetsägare, lyfta dagvattenfrågan tidigt i planprocessen samt våga arbeta mot en långsiktigt hållbar stadsplanering som inte fokuserar på kortsiktiga vinstintressen.
As a result of the changing climate precipitation and intensified rainfalls is expected to increase. This combined with an increased urbanisation and more of hard surfaces in cities causes greater pressure on exsisting storm water systems. The precipitation over Sweden is expected to increase with 10-20 percent and the run-off with 5-25 percent over the next century. Due to the urbanisation the natural drainage areas have disappeared and areas with high flood risk have been exploitated. To avoid negative consequenses in the future, sustainable storm water management is needed. Conventional storm water systems is more and more criticized of being unsustainable. The storm water issue is a highly disscused topic in Malmö as the city flooded during 2014. The focus of the study is property owner and the public water suppliers view on storm water management in a changing climate. The study uses both quantitative and qualitative methods and consists of two interviews and a supplementary questionnaire. The study’s conclusions are as followed: the need for increased cooperation with torrential rain problems in Malmö, change in legislation in terms of clarify responsibilities, determine the financing of measures, work more towards open solutions and reduce the focus on pipe-based storm water system, increase knowledge among city planners and property owners, bring up the stormwater issue early in the planning process and a determenation to work towards long-term sustainable planning rather than focusing on short- term profits.

This dissertation includes three essays on urban development theory. The first essay (in chapter 2) entitled "Tradition and Transition of Urban Development Theory: Toward A Thinking Mode Based on Organic Growth" attempts to propose an argumentation and comparison of an integrated view based on the metaphors and analogies that are embedded in the major theories or approaches in relation to urban development, and compensate for possible insufficiency in the interpretation of urban development and urban growth of the past—especially there are a fundamental shift to the rising of general systems theory, complexity sciences and the science of cities. This study suggests that the thinking mode of organicism based on organic growth achieves a profound insight which mechanization and reductionism cannot provide. If we were to expect success with the holistic and sustainable development concept for planning a city or even a whole urban system, we would need to know the complex growth potential of different facets in modern urban systems well and, furthermore, recognize the allometric nature of spontaneous emergence of cities, and then guide and assess urban development plans or decisions in accordance with these original properties. The second essay (in chapter 3) entitled "Dynamics and Planning Implications for Allometric Scaling Law between Urban Supply Networks and Taiwan Urban Areas" aims to investigate the trajectory of allometric exponents of urban supply networks in the evolution of cities, and investigates and verifies existing statistical data (Urban and Regional Development Statistics) in Taiwan from 1991 to 2010 based on log-linear forms of allometric growth and grey incidence analysis (grey sequences), to measured or clarified effect among system-related urban individuals and allometric exponents of urban supply networks. This finding indicates the following conclusions: (1) that the allometric exponents of various supply systems change over time, unlike immutable biological rhythms; (2) that the population scale of a city does not affect allometric scaling law of urban supply networks, (3) and a close relationship exists between political or economic status of individual cities and influence of individual cities affecting the allometric scaling law of urban supply networks. The third essay (in chapter 4) entitled "Urban Scaling Law and Its Empirical Findings: Revealing the Structure and Mechanism of Socioeconomic Interactions from Taiwan" aims to investigate the dynamic characteristics of allometric exponents of social interactions in the evolution of cities, and investigates and verifies existing statistical data (Urban and Regional Development Statistics) in Taiwan from 1991 to 2010 based on log-linear forms of allometric growth and grey incidence analysis (grey sequences), to measured or clarified effect among low-level entities (urban individuals) and high-level phenomena (allometric exponents) of social interactions. This finding indicates the following conclusions: (1) that the urban scale became lager, it indeed have more wealth (e.g., current income, disposable income, and savings) per capita (i.e., super-linear scaling); (2) that the urban scale became lager, the accompanying urban illness (e.g., crime cases, criminals, clearance of refuse, and expenditure grand total) were not necessarily more serious (i.e., super-linear scaling or sub-linear scaling); (3) that the individual key cities which dominant urban allometric scaling law were often have larger urban scale or relatively strong political and economic strength; (4) and the individual key cities which restrict urban allometric scaling law were often have smaller urban scale or relatively weak political and economic strength.

Abstract:
This chapter focuses on lekta as the objects of ordinary teaching. What there is to teach, and what there is to learn are lekta, say the Stoics. This claim leads to affirming the mind-independence of lekta since it is what is distinct and external from us, and yet obtains as true, that we need to be taught, especially once teaching and learning are understood as necessary steps in the natural development of reason in us. There are two methods for this developement to follow its natural course: through sense-perception leading to the acquisition of conceptions on the basis of experience, and through teaching and paying attention. The methods are not only compatible but are equally necessary to enable us to fulfil our impulse to preserve what we come to understand is most characteristic of us, as rational beings in a rational cosmos, namely reason. The Stoic theory of oikeiōsis, appropriation, is discussed in relation to the teaching and learning of lekta, as also the further question of the stages of this process of instruction. The Stoics make a distinction between two ways impressions come about in our minds: hupo, by, and epi, in relation to. A suggestion is put forward that this difficult distinction expands the distinction between the two methods, sensory and through attention, which ground the natural developement of reason. In this light, the example the Stoics take of the gymnasitics teacher, often decried as incongruous, is defened as a paradigmatic case of teaching how to pay attention to lekta, expressed through a language of the body.

At the very beginning of my essay I point out that what kind of natural and economical conditions Barcs have had in the 19th centuries. This is important becouse I had to place Barcs into this medium, which in the beginning of the 19th was a simple manorial village situated in the flood plain of the Drava. The Drava river had a great impact on the improvement of the village. This little manorial village by the end of the century became one of the determinative villages in the region of southern Transdanubia. I show why was the location of the village so importan at that time. As a vehicular interchange and with its warehouse capacity by the beginning of the 19th century it was significant too. There were five railway lines that are met in Barcs in the begining of the 20th century. So it was a significant vehicular intersection at that time. Furthermore after Kaposvár it was the second biggest industrial centre of the county. By this time it was famous about its wood and mill industries across Europe. Moreover it had a regional centre role at different types of food industries. I introduce to what kind of economical processies and infrastructural investments helped the large economical developement of the village. At the end of my essay I want to show the series of events

Abstract:
Sustainable development has always been one of the most important policies implemented by the European Union, mentioned in different treaties over time. In 2015, European Union is setting 17 Sustainable Development Goals (SDG) with 169 targets within the 2030 Agenda for Sustainable Developement. European Union is preseting the SDG 11 Goal aim ”to renew and plan cities and other human settlements in a way that they offer opportunities for all, with access to servicies, energy, housing, transportation, green public spaces, while improving resource use and reducing environmental impacts”. The EU is monitoring the progress towards SDGs for all member states through different indicators, like the recycling rate of municipal waste for SDG 11. In 2018, Romania has the recyling rate of municipal waste of only 11,11%, far away from the average of EU of 47,4%. The local public administrations have an important role in increasing the recyling rate, by providing the best services for the citizens and, in the same time, by reducing the costs of these services. In this matter, the paper presents an innovative solution regarding the waste collection in the largest District from Bucharest, Romania. The underground waste collection platforms represent and alternative for the classic platforms and the innovation comes from the smart component that they integrate, represented by the filling sensors that communicate directly to the sanitation operator. The monitoring system has direct effect by incresing the efficiency of the waste collections process, as follows: reduces the waste collection cost by 50%; improves the services provided for the citizens; predicts waste generation patterns based on data; refines waste collection processes over time; optimizes routing and navigation etc.

Studies being presented here have been done as initial part of wider research-and-developemnt (R&D) programme, aiming to investigate preconditions and all instruments set necessary for environmental governance adequate integration into legally required societal (sustainable) development governance/planning framework and municipal governance practice. This have been done studying governance by its triple complementary dimensions of governance content, governance process and governance stakeholders and approaching municipality as a complex and interactive socio-ecological system. Accordingly, pilot investigations have been done as various thematical case studies in preselected model municipalities – six studies/pilot studies, based on the integrated case study research methodology, including and complementary applying document studies, interviews, surveys, observations and focus groups. Existing development planning and other instruments combined with municipal planning capacities are neither sufficient nor effective, and, since step-wise developmental process for sustainability principle integration seems to be not perspective as quite similar also with integration principle as for complex planning process and also as for thematical meaning of integrations of environmental governance into develoment one. Since environmental sector planning documents are not mandatory anymore at local municipalities, environmental sector planning process and content in the development planning practice is often limited, but few ad hoc available and used formal environmental planning instruments are neither sufficient or used just temporaly. There is to be seen necessity to develop innovative methodologies and tools as done during this research-and-development project.

Full text
Abstract:
Advanced Thermal Reactor “Fugen” is a 165MWe, heavy water moderated, light-water cooled, pressure-tube type reactor. In February 1998, the Atomic Energy Commission of Japan decided to end the mission of ATR development and introduced a new policy that development and research of decommissioning of Fugen should be promoted in order to carry out the decommissioning smoothly after the shutdown. The Fugen NPS has shut down permanently in March 2003, and based on the report titled Activities of Fugen NPS after permanent shutdown, “Fugen” has been preparing for the project, including necessary development of technologies. The development of decommissioning for “Fugen” is divided into two areas. One area is developement of unique technology for dismantling special components such as the reactor core and the heavy water system. Another area is improvement and enhancement of existing technologies. Especially the former area requires effort and comprises development of the reactor dismantlement, tritium decontamination of heavy water system and engineering support systems. The concrete activities are as follows: The density and amount of radioactive nuclides in all equipment or concrete including the reactor core need to be evaluated for the decommissioning. To prepare for decommissioning, analysis, measurement and evaluation of the neutron flux density have been executed during reactor operation. Special dismantling process is necessary for the heavy water system and the reactor that are unique to Fugen. Some studies and tests are going on for the safe dismantling based on existing technologies and their combination. It is important to execute the decommissioning economically and rationally. Therefore, systems engineering approach is necessary in order to optimize the work load, exposure dose, waste mass and cost by selecting appropriate dismantling process at the planning stage of the decommissioning. For this reason, in order to make a decommissioning plan efficiently, we have been developing an Engineering Support System for decommissioning by adopting new information technologies such as three-dimensional- (3D-) CAD system and virtual reality (VR) system. Moreover, the technical results of technology development and decommissioning activity should be organized and opened to the public so that they can contribute to other decommissioning projects. For this purpose, information exchange and co-operation with domestic and international organizations are underway.

Kutatásunk célja egy olyan komplex hardver- szoftverrendszer létrehozása volt, amelynek segítségével megállapítható a technika elsajátításának hatékonysága labdás játékok esetén például egy kézilabdázó dobási pontosságának és dobóerejének mérése révén. A szemből és oldalnézetből készített felvételek alapján, a mozgó objektum képkockánkénti elmozdulásából számítható a labda sebessége és pozíciója a képelemzés eszközeinek segítségével. Különös figyelmet fordítottunk az eszköz költséghatékony megvalósítására, valamint fontosnak tartottuk az egyszerű kezelhetőséget a telepítés és a mérés folyamán egyaránt. Mindezt a megfelelő hardver és szoftver technológiák kiválasztásán túl az is biztosítja, hogy nem igényel külön hardver eszközt a kezelése, mivel az edzők vagy a testnevelők saját mobileszközükről férhetnek hozzá a rendszer szolgáltatásaihoz. Az egyszerű kezelhetőséget a telepítés és a mérés folyamán egyaránt szem előtt tartottuk. Ez a technológia mind módszertani szempontból, mind motivációs eszközként is figyelmet érdemel, akár edzéseken, akár az iskolai testnevelés órákon. A fenti szempontok figyelembevételével a Raspberry Pi 3B+, a hozzá csatlakozó Raspberry Pi Camera V2-es modelljére (Raspberry Pi) és az ESP32 Cam-ra (ESP32), mint hardver komponensekre esett a választásunk. A kezelőfelületet pedig egy webes alkalmazás biztosítja, amelyen keresztül megfelelő hitelesítési folyamatot követően elérhetők a rendszer szolgáltatásai. ----- Developement and measurement of ballplayers’ motoric skills ----- Our research aimed to create a complex hardware-software system that can be used to determine the effectiveness of the technique in ball games, for example by measuring the throwing accuracy and throwing power of a handball player. Based on the shots taken from the front and side views, the speed and position of the ball can be calculated from the displacement of the moving object frame by frame using image analysis tools. We paid special attention to the cost-effective implementation of the device, and we considered it important to be easy to use during both installation and measurement. In addition to selecting the right hardware and software technologies, this is ensured by the fact that it does not require a separate hardware device to manage, as coaches or physical educators can access the system's services from their mobile devices. Ease of use was kept in mind during both installation and measurement. This technology deserves attention both from a methodological point of view and as a motivational tool, whether in training or school physical education classes. Considering the above considerations, we chose the Raspberry Pi 3B+ with a Raspberry Pi Camera V2 model and the ESP32 Cam as hardware components. The user interface is provided by a web application through which the system services can be accessed after a proper authentication process.
