Tértagolás kertépítészeti eszközökkel a budapesti lakótelepek szabadterein 1950 és 1990 között
A lakóterületi szabadtereken – a közterekhez képest – lényegesen nagyobb az igény a zárt, intim léptékű terek kialakítására akár családi házak, akár lakótelepek, vagy manapság lakóparkok kertjei esetében. Így nem meglepő, hogy a lakótelepi szabadtereken, elsősorban a tömbbelsőkben a tér tagolása, intim, tartózkodásra invitáló léptékű terek
kialakítása az épített térfalakon belül fontos tervezői feladat volt a 20. század második felében. Ennek legkézenfekvőbb módja a fás növényzettel történő tértagolás, bár tereprendezéssel,
terepplasztikák alakításával is tagolható a szabadtér. Telepszerű beépítés esetén: intim, emberi léptékű, jól használható tér kb. 300-400m2, mindkét irányban kb. azonos kiterjedéssel (Karády,1983). A lehatárolt terek közötti kapcsolat biztosítása, a terek egymásba fűzése, a zöldfelületi rendszer folyamatosságának biztosítása is fontos tervezői feladat. A különböző beépítési módokhoz, különböző méretű beépítésekhez igazodva a tértagolás módja és léptéke is jelentősen változott. A kutatás célja e változások nyomon követése és okainak megismerése

Trends of Landscape Architecture in Hungary in the ‘70s
The history of landscape architecture in the seventies is part of a larger topic which covers the history of Hungarian landscape architecture from the 50-s to the end of Socialist era. The strong political pressure which was so typical in all fields of life in these periods, was determining in landscape architecture as well.
The era has not been researched yet, since it hasn’t been enough long ago to be considered as a history. The parks built at this time are disappearing due to park renovations, alterations or functional changes. These works are not protected yet; the officials of historic preservation do not consider dealing with them as a major task. We, landscape architects see in our practice these landscapes, which are facing to be renovated or altered. We have to determine if the given work should be demolished and a new fashionable landscape should be built instead of it, or it represents such a value, which deserves to be preserved, independent from the present fashion and trends. As there is no comprehensive scientific work dealing with landscape architecture of the 70-s, we can use only our instincts to decide, how valuable the given landscape is. On the other hand it is easy to realize that the open space- system of Budapest would be more uniform less diverse, if these designs would disappear.
Deep knowledge of the era could help both in making the above mentioned decision, and in understanding the recent trends and fashions. The majority of the current active landscape architects were young children in the seventies, so visual culture of these professionals is primarily determined by the works of this era.
After a life totally isolated and oriented only towards the Soviet Union in the beginning of the 50’s, the Hungarian architecture, urban planning and landscape architecture could „breathe” more free after the 1956 Revolution. The older generation of landscape architects (e.g. Professor Imre Ormos, the founder of landscape architecture in Hungary) still remembered the landscape style of the 40’s. From the 60’s each significant landscape architectural office was subscribed for the most respected professional periodical of western Europe, „Landschaft Architectur”, so the most outstanding achievements of western landscape architects and the new trends of that time were well known in Hungary, behind the iron curtain, too. In my opinion it could be considered as an important impact on the new design style of Hungarian landscape architecture, which was earlier influenced by the style of the 40-s and of the soviet social realistic examples.
The period of the 70-s was basically determined by the state-planned economy, but the unique political-economical feature of the early 70s, - the „new economical mechanism”- added new color in the political and economical life of the country.
The era cannot be understood without understanding the system and working methods of state owned planning offices, landscape construction and maintenance companies. It is important to get known the characteristic landscape designers and most important works of the period. Finally we have collect the design elements, materials, products and plants typical for the landscape design of the seventies
Explaining the Accounting Disclosure Index of Stock Exchanges by Foreign Exchange Market Activity
In this article, researcher-created accounting disclosure index of 23 stock exchanges for the year 1992 and its relationship with variables including foreign exchange turnover, economic and financial indicators were investigated. The accounting disclosure index of global stock exchanges crafted by Adhikari and Tondkar (1992) was regressed on foreign market turnover which was utilized as a proxy for foreign exchange market activity. The OLS results supported that along with the activity of foreign exchange market; GNI per capita, market capitalization, energy and electric consumption, number of listed companies were significantly related with the accounting disclosure index. The foreign market turnover was found to be positively influencing the accounting disclosure index. The models explained about 73% of the variation in the index with an F-ratio of 26.56 indicating the overall significance of the model

Green Network in Urban Pressure
Budapest is a lucky city from an urban ecological point. Thanks to the Danube cutting through the middle of the city the ventilation of downtown is adequate. The existence of this natural waterflow offers a good possibility to create a green-blue infrastructure, which can be realized in the near future by turning the Pest side embankment partially into recreational open spaces. In spite of the favourable location the air quality of Budapest is often below the critical level, first of all in the city center. Though this unfavourable situation has numerous components- first of all the difficult traffic related problems and the national and international through-traffic in the downtown – in terms of landscape architecture the biggest problem is the isolated green surface system and the lack of linear connecting elements. Due to its morphology, the Buda mountain-chain and the tectonical valleys differing in size and running towards the city center, the Buda side is in a much better position. There are the three major green wedges protruding into the city fabric till the line of the Danube, among which Devil’s Ditch (Ördögárok Creek) is the most intact one and due to its central location and length, probably the most important as well. As north-western wind is prevailing in and around Budapest, this wedge plays an essential role in ventilating the air of the city and contributes to the acceptable air quality of Budapest. This paper aims to introduce the history of the green wedge and corridor along the Devil’s Ditch. The areas next to the creek and at the bottom of the hills - as military protection zone of the Castle- remained unbuilt till the end of 18th century except for the Gellért Hill foot hill and the Tabán area. In the next two centuries some development sites were cut out here and there from the characteristic green wedge. The importance of this ventilating green corridor, although not continuous any more, was realized by the urbanism of the 20th century
Resource Allocation, Level of International Diversification and Firm Performance
This paper investigates the threads between international diversification and firm performance, resource allocation to R&D and capital expenditure. The context of this study is a resource-based view and transaction costs theory. Firms that are going international, benefit from the resources available to them outside their home country as well as from the utilization of their core competencies in other countries. Regression models without interactive terms indicate that resource allocation significantly impacts firm performance. Capital expenditure is positively associated with return on assets, while research and development expenditure undermines the firm’s performance. Analyses suggest that there is no thorough relation between international diversification and returns, regardless of using asset or sales diversification variables. The estimates of diversification variable are negative and insignificant in most models
Machine Learning-Based Hand Gesture Recognition via EMG Data
Electromyography (EMG) data gives information about the electrical activity related to muscles. EMG data obtained from arm through sensors helps to understand hand gestures. For this work, hand gesture data were taken from UCI2019 EMG dataset obtained from MYO thalmic armband were classied with six dierent machine learning algorithms. Articial Neural Network (ANN), Support Vector Machine (SVM), k-Nearest Neighbor (k-NN), Naive Bayes (NB), Decision Tree (DT) and Random Forest (RF) methods were preferred for comparison based on several performance metrics which are accuracy, precision, sensitivity, specicity, classication error, kappa, root mean squared error (RMSE) and correlation. The data belongs to seven hand gestures. 700 samples from 7 classes (100 samples per group) were used in the experiments. The splitting ratio in the classication was 0.8-0.2, i.e. 80% of the samples were used in training and 20% of data were used in testing phase of the classier. NB was found to be the best among other methods because of high accuracy (96.43%) and sensitivity (96.43%) and the lowest RMSE (0.189). Considering the results of the performance parameters, it can be said that this study recognizes and classies seven hand gestures successfully in comparison with the literature
