Attitude of Hungarian Young Adults Towards Bank Loans: The Risk Mitigation Trap
Authors: Béres Dániel , Huzdik Katalin
Published: March 2022

The aim of this study is to examine the attitude of young adults (18–25 years) towards bank loans. For the analysis we used two primary data sources (financial literacy surveys were executed in 2013 and 2020). The samples are non-representatives, the number of involved survey participants exceeded 1,740 in both cases. The survey included 6 sections with open and closed questions, as well as likertscales. It was found that the attitude of young adults towards the loans is negative. Between the 2013 and 2020 surveys the economic cycle showed prosperity. As a result, the respondents devalued the importance of the loans in the economy. Besides, the extreme rejection of having a bank loan was also mitigated. As for the bank loan experiences of the respondents it was found that the purposes of the borrowed loans are along the good criteria of financial literacy – the spendings examined can be considered as an investment for the future. Regarding the satisfaction level of the respondents with the bank loans the most important satisfactory factor was the expectations for the future. The measures taken after 2008 financial crisis such as re-defining consumer friendly lending and executing population supporting policy involving credit institutions resulted a mild positive effect on the attitude of the young adults towards bank loans. Risk avoidance results a trap situation that is against financial inclusion and results disequilibrium in demand and supply of banking services. The effect of the so called ‘risk mitigation trap’ can be reduced by developing the financial literacy.
Ambivalent Change in CDS Spreads in 11 Euro Area Countries
Authors: Török László
Published: March 2022

One of the macroeconomic consequences of the COVID-19 epidemic is that the global economy has seen a robust increase in the countries‘ gross external debt and the sovereign public debt that is part of it. Nor have the eurozone Member States escaped this effect. The increase in gross external debt and sovereign government debt also means that it has become theoretically more risky for investors to buy debt securities (typically bonds). Theoretically, however, it follows that as a result of the increase in risks in the country, CDS spreads had to rise as well. The study uses a correlation calculation to show that the development of the price of CDSs is more closely correlated with gross government debt than with gross external debt. Using hierarchical cluster analysis, the study groups the countries of the Eurozone. The basis for clustering is the close relationship between a country‘s gross government debt and its CDS spread over the period under review. A relevant conclusion of the study is that the increase in gross government debt was not followed by an increase in CDS spreads because the financial source of the increase in government debt was different from previous years.
Helikopterpénz és alapjövedelem, vagy munkaalapú társadalom? : A munkabér, a segély, a hitel és a mennyiségi lazítás rövid története
Authors: Vargha Bálint Tamás
Published: March 2022

A koronavírus-járványt követően – különösen mielőtt az infláció ennek az időszaknak egyik meghatározó tényezőjévé lépett elő – több válságkezelést célzó javaslat is szóba hozta az univerzális alapjövedelem lehetőségét, amelynek fedezetét a jegybanki pénzteremtés jelentheti. Az alábbi írás műfaja esszé, amely arra tesz kísérletet, hogy a helikopterpénzzel és az alapjövedelemmel kapcsolatos felvetések politikai gazdaságtani jelentését és következményeit ragadja meg. Nem spórolható meg, hogy az érték-, a munka- és a pénzteremtés történetébe is visszaillesszük ezt az alapvetően elosztási kérdésként bemutatott javaslatot. A helikopterpénz ebben a fénytörésben az extenzív növekedés egyik új paradigmájának látszik, amely első pillantásra pénzügyi innováció, azonban paradox módon az érték inkább prekapitalista képzetével mutat rokonságot. A helikopterpénz emellett olyan munkabért helyettesítő transzfer, amely nem ad választ a munka helyén megjelenő társadalmi és szimbolikus űrre. Szociális eszközként tűnik föl, miközben csak termelés és fogyasztás globális kettéválasztásán nyugodhat. A helikopterpénz a mennyiségi lazítás folytatása más eszközökkel, amely kendőzetlenül mutatja meg a pénzteremtés motivációit. Az ’érték munka nélkül’, a ’gazdaság ember nélkül’ gondolatkísérletének nyitánya.
Mezőgazdasági nyugdíjak finanszírozása az európai kontinensen
Authors: Giday András , Tatay Tibor
Published: March 2022

Európában a mezőgazdaság támogatása egyrészt az élelmiszerellátás biztosítása, másrészt a vidéki életmód fenntarthatósága miatt fontos. Az utóbbi évtizedekben azonban a vidéki lakosságot is érinti a népesség öregedése. Az európai országokban – a mezőgazdasági ágazat sajátosságait figyelembe véve – különböző mezőgazdasági nyugdíjrendszerek jöttek létre. A nyugdíjalapok jellemzően ott kaptak nagyobb súlyt, ahol jelentős volt a kisebb gazdaságok szerepe és teljesen bismarcki típusú volt a nyugdíjrendszer. Általában nem vezettek be ilyet ott, ahol 1990 előtt „kolhozrendszer” működött Kelet-Közép-Európában. Tanulmányunkban a különböző megvalósított formákat vizsgáltuk meg, áttekintettük az utóbbi évtizedekben végbemenő változásokat és feltártuk, hogy az egyes országokban akár 75–85 százalékban is kiegészítették az államok a járulékbefizetéseket a nyugdíjkifizetések biztosításához. Módszertanunk a dokumentumelemzés és az összehasonlító értékelés. Álláspontunk szerint társadalmi, környezeti célokat szem előtt tartva érdemes speciális ágazati szempontú támogatással, életpálya-finanszírozással, illetve nyugdíjakkal arra ösztönözni a gazdákat, hogy kisebb gazdaságokban is tovább folytassák a termelést.
A CDS-felárak ambivalens változása az eurózóna 11 országában
Authors: Török László
Published: March 2022

A Covid–19-járvány egyik makrogazdasági következménye az, hogy a világgazdaságban robusztusan növekedtek az országok bruttó külső adósságai és az ennek részét képező szuverén államadósságok is. E hatás alól az eurózóna tagországai sem tudták magukat kivonni. A bruttó külső adósságok és a szuverén államadósságok növekedése egyben azt is jelenti, hogy elméletileg kockázatosabbá vált az adósságokat finanszírozó értékpapírok (jellemzően kötvények) vásárlása a befektetők számára. Teoretikusan ebből viszont az következik, hogy az országkockázatok növekedésének következményeként a CDS-ek felárainak is emelkedniük kellett. A tanulmány korrelációszámítással mutatja ki azt, hogy a CDSek árának alakulása szorosabban korrelál a bruttó államadóssággal, mint a bruttó külső adóssággal. A hierarchikus klaszteranalízis módszerével csoportokba rendezi a tanulmány az eurózóna országait. A klaszterberendezés alapja az, hogy mennyire szoros kapcsolata van az adott ország bruttó államadóssága és CDS-felára között a vizsgált időszakban. Releváns következtetése a tanulmánynak, hogy a bruttó államadósság növekedését nem követte a CDS-felárak emelkedése azért, mert az államadósság növekedésének a pénzügyi forrása más volt, mint a korábbi években.

Analysing the impact of green information system, green packaging, reverse logistics on logistics performance in the construction industry
Authors: Bikissa-Macongue Marie Brinda , Chinomona Elizabeth
Published: March 2022

Objective - Due to their prominent position in the market, construction companies are increasingly required to control and minimise the internal and external environmental impact of their day-to-day activities. To achieve this, all over the world, construction companies have gradually adopted different environmentally-friendly practices promoting the preservation of the environment. Generally, many of these practices are carried out in the area of green supply chain management (GSCM) and logistics performance where there is a great potential to reduce the rate of pollution generated. Therefore, the purpose of the study is to analyse the effective GSCM factors which are green information systems, green packaging, and reverse logistics necessary to improve the logistics performance of their companies.

Methodology/Technique - For this study, a quantitative approach was adopted. A judgmental or purposive sampling technique was applied to collect data from 400 respondents. Data were analysed with the aid of two software namely, Statistical package for social science (SPSS 27.0) and Analysis of moment structures (AMOS 27.0). In addition, Confirmatory factors analysis and Structural equation modeling were used to analyse the relationship between constructs and test the hypotheses.

Finding/Novelty - In addition, the study implied that construction companies that comply with the different laws and regulations established, develop and implement a green information system, as well as a good reverse logistics system, are more likely to reduce the environmental impact of their activities, while optimising their economic viability. The study suggests that by adopting GSCM and improving their logistics performance, construction companies will be able to improve their environmental performance. Therefore, it is recommended that construction companies keep giving more attention to GSCM and logistics performance as it is the most innovative means by which they can get cost efficiency and environmental responsibility simultaneously.

Authors: BALIK İsmet , AYDIN Sonay Zeki , BİTİKTAS Fevzi
Published: March 2022

Bu çalışmada, İstanbul ve Çanakkale Boğazlarından geçen gemilerin tiplerine ve yıllara göre dağılımları, kılavuz alan gemilerin oranları, kazalar ve gemilerin geçiş için bekleme süreleri incelenmiştir. Elde edilen bulgular, 2006-2020 yılları arasında İstanbul ve Çanakkale Boğazlarından geçen gemi sayılarının tedrici olarak azaldığını göstermektedir. Gemi sayılarının aksine, her iki boğazdan da geçen gemilerin toplam tonajları artmıştır. Gerek İstanbul gerekse Çanakkale Boğazı’ndan 2010 yılından sonra geçen 200 m’den büyük gemilerin sayısı artarken, 500 GT’dan küçük gemilerin sayısı azalmıştır. İstanbul ve Çanakkale Boğazlarından geçişte, kılavuz alan gemilerin oranı, gemi büyüklüğüyle artmıştır. Boyu 100 m’den küçük gemilerin ise çok azı kılavuzluk hizmeti alırken, İstanbul Boğazı’ndan geçen 200 m’den büyük gemiler ile Çanakkale Boğazı’ndan geçen 300 m’den büyük gemilerin tamamı kılavuzluk hizmeti almıştır. İstanbul Boğazı’nda, 1 Mayıs 1982-30 Haziran 1994 tarihleri arasını kapsayan dönemde 12,92 kaza yıl-1 meydana gelirken, 1 Temmuz 1994-31 Aralık 2003 arasını kapsayan dönemde 12,33 kaza yıl-1 ve 1 Ocak 2004-31 Aralık 2019 tarihleri arasını kapsayan dönemde 7 kaza yıl-1 meydana gelmiştir. Çanakkale Boğazı’nda meydana gelen gemi kazalarının sayısı da az da olsa son dönemlerde azalma göstermiştir. Boğaz geçişi için gemilerin bekleme süresi 2010-2019 yılları arasında ortalama; İstanbul Boğazı için 13,9 saat, Çanakkale Boğazı için ise 5,4 saat olarak belirlenmiştir. Bekleme süresi son 10 yıl içerisinde İstanbul Boğazı’nda önemli bir değişiklik göstermezken, Çanakkale Boğazında son yıllarda yaklaşık iki saat artmıştır.
Şehirlerde Daralmanın Sonuçlarının ve Geleceğe İlişkin Öngörülerin Farklı Ülke Örnekleri Çerçevesinde Tartışılması
Authors: ALİEFENDİOĞLU Yeşim , URAL KESKİN Esra
Published: March 2022

Avrupa başta olmak üzere 1990’lı yıllardan başlayarak, doğum oranlarının düşmesi ve nüfusun yaşlanması ile demografik dönüşümün ortaya çıkması bazı şehirlerin nüfuslarını kaybetmesine neden olmuştur. Nüfusun öngörülenden fazla azalması vergi gelirlerinin düşmesine, teknik altyapı sistemlerinde kapasite fazlalarının oluşmasına, bakım ve işletim maliyetlerinin artmasına, sosyal donatı alanlarının terk edilmesine ve sonuç olarak da bu alanların çöküntü alanlarına dönüşmesine ve özellikle şehir merkezi dışında yeni yerleşim alanlarının oluşturulması ve şehir merkezinde yaşayan nüfusun bu bölgelere kaymasına neden olmuştur. Kamu politika ve stratejileri de şehirlerin daralması süreçlerinde etkili aktörler olmuşlardır. Literatürde daralma açısından özellikle incelenmiş olan ülkeler seçilerek farklı daralma nedenleri tespit edilmiştir. İstatistiksel veriler ışığında Türkiye’de daralmaya ilişkin veriler toplanarak hem geleceğe ilişkin öngörüler belirlenmiş hem de politikalar incelenmiştir. Bu çalışmada hem ekonomik hem de demografik değişimi kapsayan çok boyutlu bir bakış açısıyla daralan şehirleri tartışmak amacıyla temel bir yaklaşım geliştirilmeye ve çözüm önerileri sunulmaya çalışılmıştır. Kentsel daralmanın planlama aşamasından başlayarak öngörülmesi ve kentsel yayılmanın kontrollü bir şekilde gerçekleşmesi gerektiği varsayımı altında; daralmaya başlayan şehirlerde vergilerin düşürülmesi, yeni iş imkanlarının sunulması ve şehirlerin sosyal ve ekonomik açıdan daha cazip hale getirilmesi çözüm önerisi olarak tartışılmıştır.

Published: March 2022

Extreme ultraviolet (EUV) lithography is already being applied to the high-volume manufacturing of semiconductor devices. Although EUV lithography has enabled fine pitch scaling, such sub-20 nm order fabrication has also imposed the issue of stochastic defects (in the form of randomly generated line bridges and breaks). To resolve such an issue, understanding the development process is essential. In this study, the dissolution dynamics of three types of EUV photoresist were investigated for four types of alkaline developer using a quartz crystal microbalance method to clarify the swelling and dissolution kinetics during photoresist development. In experiments, tetramethylammonium hydroxide (TMAH), tetraethylammonium hydroxide (TEAH), tetrapropylammonium hydroxide (TPAH), and tetrabutylammonium hydroxide (TBAH) aqueous solutions were used as developers. Poly(4-hydroxystyrene) (PHS)-type, acryl-type, and hybrid-type photoresists were examined. The effect of the alkyl chain length of tetraalkylammonium cations depended on the type of photoresist. The dissolution dynamics depended on the combination of types of photoresist and developer.

Bahan pembersih gigi tiruan terbukti efektif mengurangi plak dan organisme mikro pada gigi tiruan. Akan tetapi penggunaan pembersih gigi tiruan dari bahan kimia selain mahal juga dapat menyebabkan kerusakan yang signifikan pada basis gigi tiruan karena pembersih gigi tiruan dapat menyebabkan hilangnya komponen larut dan peliat, atau penyerapan air oleh bahan basis. Berdasarkan hal tersebut penggunaan bahan alami, yaitu biji alpukat, menjadi pembersih alternatif. Pada penelitian eksperimen laboratorium ini menggunakan uji eksperimen dengan teknik disc diffusion. Bahan yang digunakan adalah varietas hijau panjang atau alpukat mentega yang diperoleh di perkebunan Malino, Sulawesi Selatan. Daya hambat diketahui berdasarkan pengukuran diameter zona inhibisi yang terbentuk di sekitar paper disc, dengan menggunakan jangka sorong. Hasil penelitian menunjukkan bahwa uji daya hambat ekstrak biji alpukat sangat signifikan, yaitu konsentrasi 2% dengan rata-rata 11,51 mm, konsentrasi 4% dengan rata-rata 12,39 mm, konsentrasi 6% dengan rata-rata 13,61 mm, konsentrasi 8% dengan rata-rata 13,53 mm, dan konsentrasi 10% dengan rata-rata daya hambat mencapai 15,02 mm. Luas zona tersebut melewati zona yang dihasilkan oleh Ampicillin sebagai kontrol positif, yaitu 14,22 mm. Disimpulkan bahwa biji alpukat memiliki aktivitas antibakteri yang cukup tinggi sehingga berpotensi sebagai antibakteri terhadap Streptococcus mutans.

Background: Malocclusion is a condition that is not in accordance with the process of growth and development that can be seen with the disharmony of the relationship between the teeth, relationship of jaw arches, face and overall. The 2D:4D ratio can be corelated with hormones that have a role in growth.Therefore, ratio 2D:4D can be used as an early marker of disease, intelligence, reproductive ability and probability of jaw growth patterns. Objective: To know the relationship between the ratio of second and fourth digit lengths (2D:4D) and the types of malocclusion on the students of Unismuh Junior HighSchool. Method: This observational descriptive study with purposive sampling was performed on students aged 13-15 years old with total sample 100 people.Malocclusion examination was conducted to identify the types of Angle and Dewey malocclusion. A digital vernier caliper was used to measure a ratio between2D and 4D. The data were analyzed using chi-square test. Result: 96 people had Class 1 (2D<4D=77, 2D>4D=19), 4 people had Class 2 (2D>4D=3, 2D<4D=1), Class 1 type 1 of 34 people (2D< 4D=29, 2D>4D=5), Class 1 type 2 of 3 people (2D<4D=2, 2D>4D=1) and Class 1 type 6 of 16 people (2D<4D=12,2D>4D=4). Conclusion: There was no relationship between the ratio 2D:4D with the types of Angle and Dewey malocclusion.

We present a live streaming app for Android And iOS devices and Web using URL. The app is useful for three reasons first, all your favorite radio stations will be grouped in one place, and hence, you can easily play and switch from one station to another without any hassle. Second, it is an app that turns your device into a radio setting you listen to live streaming stations while in the office, on the road, or in any other setting. Third, it is the Voice assistant-based app that takes input from the User command and plays channel according to the command. The app is similar to Spotify but on a smaller scale. This application provides a facility to listen to your favorite music anytime, anywhere. It provides live streaming from radio stations all around the globe. It is distinct from on-demand file serving. Internet radio is also distinct from podcasting, which involves downloading rather than streaming. Many Internet radio services are associated with a corresponding traditional (terrestrial) radio station or radio network. Internet using radio stations are independent of such associations. Internet radio services are usually accessible from anywhere in the world. The app has two main contributions: 1) We describe all the steps and components needed to develop such an app. 2) We also discuss the functionality and the trade- offs using different components and approaches. Radio audiences will be formed of all segments of society even people who are handicapped.

In this paper the different dielectric covers affects on square patch antenna is investigated and compared their performance. The square patch antenna is designed at 2.4GHz with arlon diclad 880 substrate. The dielectric constant of substrate is 2.2 and thickness of substrate is 1.6mm. The different dielectric covers or superstrates are used whose dielectric constants are 2.2, 3.2, 4.8 and 10.2. The patch antenna is simulated using Ansoft electromagnetic simulator such as HFSS. The effect of dielectric cover at height (H) =0 on patch antenna, the result is the performance of antenna is slightly decreased and as increase the height of the dielectric cover above the patch performance antenna is slightly increases as increases height of the dielectric cover above the patch, but at optimum height, performance of the cover results which is same the antenna without dielectric cover. The uses of dielectric covers are used to providing protections from physical damage, rain and snow and also protecting the antenna from physical heat and other environmental hazards. This antenna designed specifications and frequency 2.4GHz is used in wireless applications.
Accuracy of narrow-band spectral indices estimation by wide-band remote sensing data
Authors: Stankevich Sergey
Published: March 2022

Narrow-band spectral indices are quite informative and important in various applications of remote sensing – to assess the condition of vegetation, soils, water bodies and other land surface formations. However, direct measurement of narrow-band spectral indices requires hyperspectral imaging. But most of modern multispectral aerospace imaging systems are wide-band. Accordingly, it is not possible to calculate the narrow-band index directly from wide-band remote sensing data. This paper discusses approaches to the narrow-band spectral indices restoration by wide-band remote sensing data using statistical models of interrelations of narrow- and wide-band indices itself, of source wide-band and narrow-band signals in close spectral bands, as well as of land surface reflectance quasi-continuous spectra translation from wide bands to narrow ones.The experimental accuracy estimation of narrow-band spectral indices restoration by wide-band multispectral satellite image is performed. Three most complicated narrow-band spectral indices, which covering a range of spectrum from visible to short-wave infrared, were considered, namely – the transformed chlorophyll absorption in reflectance index (TCARI), the optimized soil-adjusted vegetation index (OSAVI) and the normalized difference nitrogen index (NDNI). All three mentioned methods for narrow-band spectral indices restoration are analyzed. The worst result is demonstrated for regression-restored signals in spectral bands, and the best result is for the spectra translation method. Therefore, the method on the basis of spectra translation is recommended for practical implementation.
