Authors: Antonić Roland , Janković Slobodan , Folić Marko 
Published: December 2021

Abstract

Introduction
Professional drivers’ knowledge about driving-impairing medications is not satisfactory. The aim of this study was to develop and test the reliability and validity of the questionnaires designed to measure the knowledge and attitude of professional drivers about the influence of various medications on driving ability.

Methods
The questionnaires for assessing professional driver’s knowledge (performance-based) and attitudes about influence of various medications on driving abilities were developed by creating the item pool, testing reliability and validity, and factor analysis. The study was conducted as a multicenter, cross-sectional study in Serbia and Bosnia and Herzegovina. The study population consisted of professional drivers, who filled out both questionnaires in three time intervals.

Results
Both questionnaires showed great internal consistency and temporal stability. Cronbach’s Alpha for the first questionnaire was 0.984 and for the second it was 0.944. The Kaiser–Meyer–Olkin test for the first questionnaire confirmed sampling adequacy with its value of 0.964 and for the second questionnaire it was 0.933. Exploratory factor analysis of the questionnaire showed that three factors were revealed after rotation for the first questionnaire and they explained 78.0% of variance. Both questionnaires showed high degree of correlation between scores after the first and repeated administration, Spearman’s rho coefficient of correlation for was 0.962 and 0.980.

Conclusion
Based on the results of this study, we believe that both questionnaires are useful tools for testing professional drivers’ knowledge and attitudes about the influence of medications on driving ability.

Published: December 2021

Abstract
The Artificial Thickened Flame (ATF) method, which involves artificially increasing the flame thickness so as to simulate with a coarse grid resolution, is applied to reduce the computational cost of predicting the Deflagration to Detonation Transition (DDT) in a tube with repeated obstacles. While simulation results depended on the parameter N (the number of grid points in laminar flame thickness), it was found that N values of more than 10 may be excessive. The results show that the chosen simulation method predicts the flame speed as compared to a reference experiment and captures the detail of the strong ignitions near the corner between the obstacle and the sidewall. The present simulation also captures the wrinkle flame front structure during the acceleration of flame.

Abstract
Given the rising importance of unmanned aerial vehicles (UAVs), this article addresses the urgent scientific problem of determining the aerodynamic characteristics of a UAV while laying out the propellers for the wings. We discuss the methodology for experimental wind-tunnel studies of aircraft configurations with propellers. It is shown that a characteristic feature of the configuration small-elongation wing with propellers is the absence of elements that are not affected by propellers. This feature makes it difficult to implement and automate a wind tunnel experiment, since there are problems with providing similar criteria for a working propeller; it is difficult to achieve perfect balancing for solid drive propellers, which causes vibration, the level of which depends on uncontrolled factors; the inability to neglect the presence of the body elements influence to the blades of propellers; the difficulty of direct measuring propeller thrust and torque. The presented methodology involves the integrated usage of experimental and numerical methods to eliminate the difficulties in conducting physical experiments in a wind tunnel. This approach makes it possible to combine the high credibility of experimental data in the study of the physical essence of phenomena with high efficiency and accuracy in determining aerodynamic characteristics by numerical methods. Using this approach, we established dependences of the aerodynamic characteristics of the small-elongation wing configuration with counter-rotating propellers on the geometric and kinematic parameters of the configuration for other extensions and constrictions of the wings. These data can serve as the basis for the development of recommendations for the selection of sensible geometric parameters of the aerodynamic configuration of a small-elongation wing with counter-rotating propellers.

Published: December 2021

Abstract
An electric hoist could be considered as the most important component of an electric overhead crane. Electric hoists are material handling equipment used for lifting, lowering, and transporting materials and products. They are powered by an electric motor and have a controller to adjust the lifting parameters. Three-phase induction motors are most often used as electric lifting motors for bridge cranes. This paper concerns the design of the power of the electric lifting motor for an electric hoist of the single girder bridge crane with the 500 kg load capacity. It represents the design of the electric lifting motor according to a commonly used scheme for the design of electric motors, from the power at a uniform load to the relative load of the motor. Based on the input data, the necessary motor parameters are calculated using Microsoft Excel. The main parameter is the static power of the motor, the calculated value of which is 0.823 kW. Based on the value of this power, a three-phase induction motor 1.1 kW, MS90-4 is selected. This electric lifting motor is suitable for the above-mentioned bridge crane, as it meets the condition of torque overload.

Published: December 2021

Abstract
The peripheral regions of Hungary, such as the Northern Hungarian region and its settlements, are facing a variety of problems and challenges, and in addition to economic difficulties, demographic and labour market challenges also demand increased attention and solutions. Since the change of regime, the region has been facing economic and labour market difficulties. The current labour market faces a combination of labour shortages, automation and robotisation, rapidly changing conditions and high unemployment. In most peripheral regions, the availability of labour resources to meet the needs of the primary labour market is very limited and local labour markets are completely depleted. The unemployed lack skills and experience. The aim of the study is to provide an overview of labour market developments in the Northern Hungarian region since the change of regime and to describe successful local developments. Addressing the situation requires local, municipal-level solutions, which is a real challenge, as there is no single recipe. Local development can and should be built on a toolbox of local development, as solutions based on local resources, local ‘heroes’, local control and local ideas can be successful. The paper describes such successful local development.

Published: December 2021

Abstract
Cities play a key role in EU regional policy, and to this end the Leipzig Charter called for the development of Integrated Urban Development Strategies (IVS) emphasizing an integrated approach in the 2007–2013 budget period, which was replaced in the period 2014–2020 by Integrated Settlement Development Strategies (ITS). We can find many experiments in the methodological elaboration of the measurement of regional and municipality development in the Hungarian and international literature. However, due to the complexity of the topic, no more widely accepted procedure has emerged, however, there is a common consensus that development is treated as a complex phenomenon. In the present study, we attempted to examine the development of the city of Gyöngyös through a complex system of indicators for the period 2010–2018. In addition, an important part of our research is to supplement the results obtained with statistical data and, if possible, to compare them to the subjective judgment of the residents. Our main goal was to answer how the changes of the indicator groups in the indicator system and their totality are perceived by the residents.

Published: December 2021

Freedom of the press regulations are adhered to by various countries, including Indonesia and Sweden. Every nation wants their country to be free, and uphold freedom of expression and human rights. Sweden is the first country to regulate freedom of expression by enacting Freedom of the Press Act in 1766, while Indonesia has so far implemented Law No. 40 of 1999 on the Press. This article highlights how freedom of the press is implemented in Indonesia so that its index of democracy and freedom of the press is equal to that of Sweden. This research applies a literature study method and uses secondary data from various books, journals and legislations. The researcher concludes that some groups encourage the revision of Law No. 40 of 1999 with certain conditions, while others are opposed to it. The other groups stated that the law is lex specialis derogate legi geneari and is used in case of press dispute so that journalists can no longer be imprisoned due to their profession.

This research has been conducted in the Biotechnology Laboratory in Damascus University_ Damascus, Syria where the genetic diversity of fourteen cultivars of figs (Ficus carica L.) growing in Swaida governorate which located in the south region of Syria were investigated using (Simple Sequence Repeats) SSRs technique, where 4 cultivars of them were genotypes scattered in the local fields without any scientific taxonomy and farmers did not classify them properly. Eight pairs of SSRs markers were used depend on their ability to separate between fig cultivars as mentioned in previous studies, six pairs of them gave amplified products in the polymerase chain reaction (PCR), while MFC3 and MFC6 primers did not give any amplification products. A total of 17 alleles were detected at six SSRs loci. The alleles number per locus ranged from 2 to 4 with an average of 2.83 alleles/locus. The observed heterozygosity (Ho) was 0.33, while the expected heterozygosity (He) was 0.17. The mean value of genetic similarity was 0.69 where fig cultivars has separated into two clusters in Cluster Analysis, which confirms a significant genetic similarity between most of the cultivars. MFC1 and MFC2 loci gave about 0.67 and 0.61 PIC (Polymorphism Information Content) values respectively, which confirms their ability to study the genetic diversity of fig cultivars more than other loci. F1 and F2 cultivars greatly affect the quality of the fruits as paternity traits as Caprifigs. Tammozi cultivar has low values of its genetic similarity with the rest of the cultivars which reflect great difference between it and other cultivars. Generally, the challenges in this study were in characterizing unrecognized fig cultivars in southern Syria to distinguish between them as they were not certified in agriculture ministry in Syria because the lack in studies related to the same topic as these cultivars were not studied before, thus, we managed to make a significant contribution in certifying fig cultivars in Syria using SSR technique.

AbstractThe focus of this research is to identify regulations governing the implementation of criminal case trials using teleconference media in Indonesia and to analyze the legality of these trials during the COVID-19 pandemic. This research is a normative legal research. Legal materials are obtained through literature study and interviews with legal practitioners, then processed qualitatively. Based on the results, the author obtained two conclusions. First, regulation of criminal case trials using teleconference media in Indonesia has been regulating in several laws in Indonesia. Second, the implementation of the trial during the COVID-19 pandemic, which required the defendant to remain in prison, was contrary to the principle of the defendant's presence at trial as regulated by the Criminal Procedure Code. Besides, the legal-based in the form of a circular cannot override the Criminal Procedure Code. Meanwhile, the legal umbrella in the form of an agreement is not appropriate considering its dimensions are private and only bind the parties. Keywords:criminal trials, teleconference, the COVID-19 pandemic AbstrakFokus pembahasan penelitian ini adalah mengidentifikasi peraturan perundang-undangan yang mengatur pelaksanaan sidang teleconference di Indonesia dan menganalisis legalitas persidangan perkara pidana yang memanfaatkan media teleconference di masa pandemi COVID-19. Penelitian ini merupakan penelitian hukum normatif. Bahan hukum diperoleh melalui studi kepustakaan dan wawancara dengan praktisi hukum yang kemudian diolah secara kualitatif. Berdasarkan hasil penelitian, Penulis memperoleh dua kesimpulan. Pertama, pemeriksaan sidang perkara pidana melalui media teleconference di Indonesia sudah diatur dalam beberapa peraturan perundang-undangan di Indonesia. Kedua, pelaksanaan persidangan tersebut di masa pandemi COVID-19 yang mengharuskan terdakwa tetap berada di Rutan/Lapas bertentangan dengan asas kehadiran terdakwa di persidangan sebagaimana diatur oleh KUHAP. Selain itu, payung hukum berupa surat edaran bukan merupakan peraturan perundang-undangan sehingga tidak dapat mengenyampingkan KUHAP. Sedangkan, payung hukum berupa perjanjian kerja sama tidaklah tepat mengingat dimensinya yang bersifat privat dan hanya mengikat para pihak.

Objetivo: Identificar a importância da prática dos cuidados paliativos nos tratamentos de pacientes terminais, visando compreender e satisfazer todas as necessidades das esferas psicoemocional, orgânica, social e espiritual. Revisão bibliográfica: Observou-se que os cuidados paliativos são de vital importância, uma vez que se preocupam em promover a qualidade de vida dos pacientes e familiares, com sensibilidade de considerar diversos aspectos da vida dessas pessoas, preparados no enfrentamento das adversidades que implicam um tratamento terminal. É importante salientar também que a presença multiprofissional se diz fundamental para maior compreensão dos casos e manejo clínico adequado, mesmo que ocorram dentro de ambientes hospitalares. Considerações finais: Finalmente, salienta-se o reconhecimento da união entre Psicologia e Medicina, por exemplo, demonstra que o bem-estar do paciente não pode ser limitado em apenas um departamento da saúde, por isso que a comunidade científica deve estar atenta aos efeitos benéficos da prática dos cuidados paliativos como uma forma de tratamento de escuta ativa, atenção integral, e preocupação ao direito básico à dignidade humana.

Published: December 2021

Сейсмическая активность является одним из источников изменчивости ионосферы. В данной работе на основе методики [1] исследовано изменение концентрации электронов в ионосфере, предшествующее наступлению сильных землетрясений с M ≥ 6.0 в Камчатском регионе. Данная методика основана на вычислении коэффициента корреляции между значениями критической частоты foF2 двух ионосферных станций, одна из которых расположена внутри зоны подготовки землетрясения, а другая – за ее пределами. Рассмотрены данные, полученные на двух станциях PETROPAVLOVSK (PK553) и EARECKSON (EA653) за период 01.09.2018–30.04.2021 гг. Статистический анализ критических частот foF2 показал, что для 6 из 8 землетрясений с M ≥ 6.0, произошедших на глубинах до 100 км и эпицентральных расстояниях до 500 км от расположения PK553, за 1–12 суток до их наступления предшествовало заметное уменьшение коэффициента корреляции.
Seismic activity is one of the sources of ionospheric variability. In this work, we investigate electron concentration change in the ionosphere, preceding the onset of strong earthquakes with M ≥ 6.0 in Kamchatka region. The research technique is based on calculating the correlation coefficient between the critical frequency foF2 values at two ionospheric stations. One of them is located inside the earthquake preparation zone, and the other is outside it. The data obtained at two stations PETROPAVLOVSK (PK553) and EARECKSON (EA653) for the period 01.09.2018–30.04.2021 are considered. Statistical analysis of the critical frequencies foF2 showed that a noticeable decrease in the correlation coefficient was observed 1–7 days before the earthquakes for 6 out of 8 events with M ≥ 6.0 that occurred at depths of up to 100 km and epicentral distances of up to 500 km from the PK553 location.

В данной работе показано, как изменялось взаимодействие между тропосферой и стратосферой в последние десятилетия. Также оценено влияние таких явлений, как квазидвухлетнее колебание (КДК) на данное взаимодействие. Для этого было проанализировано распространение планетарных волн в атмосфере с использованием трехмерных потоков волновой активности, показана временная изменчивость потоков и линейный тренд. Кроме того, была оценена реакция тропосферы над Сибирью и Восточной Азией на КДК.
The study of the variability of stratosphere-troposphere coupling during the last decades is considered. The influence of such phenomena as quasi-biennial oscillation (QBO) on this interaction was also estimated. For this, the propagation of planetary waves in the atmosphere was analyzed using three-dimensional wave activity fluxes. The temporal variability of fluxes and a linear trend was shown. In addition, the response of the troposphere over Siberia and East Asia to the QBO was assessed.
