Social activity of Carpatho-Ukrainian students in interwar Brno (renovation according to the found sources)
Authors: Kutsov Kostiantyn
Published: December 2021

For today the social activity of Carpatho-Ukrainian students in Brno is known to be the least studied issue in the history of the Carpatho-Ukrainian student movement in the period of interwar Czechoslovakia. Based on all available archival and published sources, in this study the attempt is made to reconstruct and analyse the process of formation and development of public activity of Ukrainian students (natives of modern Transcarpathian region (Ukraine) and Presov self-governing region (the Slovak Republic)), who in the 1920 – 1930s studied at higher education institutions in Brno (the University named after Masaryk, High Technical School, High Vet School). The author of the article states that the social activity of Carpatho-Ukrainian students in Brno developed in several stages. The first stage is the second half of the 1920s, the period when Prague student associations such as the Ukrainophile Union of Subcarpathian Students; and the Russophile society Vozrozhdenie (Rebirth) extended their activities in Brno some local students not only became their members but also formed some of their non-formal centers in Brno (e.g. Union of Subcarpathian Ruthenian Students). However, due to the decrease in the number of Carpatho-Ukrainian students at local universities, this process soon slowed down. Next stage is the second half of 1930s. At that time, relatively large independent Carpatho-Ukrainian student organizations – Russophile Society Verkhovina (1936) and the Subcarpathian Academic Society (1937) formed and gradually intensified in their activity in Brno. However, due to the political situation in the Czechoslovak Republic in 1938 – 1939, their activities ended. More information about the issue discussed in the article can be found in the original documents kept at the archival institutions of Brno.
Extensions to the main building of Lviv Polytechnic at the beginning of the XX century
Authors: Kurdyna Yuliia
Published: December 2021

The article deals with the problem of building up the educational premises of Lviv Polytechnic National University (official name at the time - Imperial Royal Higher Technical School in Lviv) in the early 20th century. The attention is drawn to the reasons that determined the necessity to extend the educational space for the institution, given its development and increased social significance. Based on the analysis of archival materials, the author traces the construction process in detail: from the official permit for extension in May 1903 to the implementation of the project. The persons who were engaged in the Building Committee, formed by the Galician governorship, and the sphere of their responsibility are indicated. The way of conducting such works at that time is specified: a sort of tender was held and a contract for execution of works was signed with a winner (a company that offered the lowest price). The particular enterprises, type of work performed (construction, carpentry, metalwork, etc.) and the amount of money paid are indicated. For example, the extension was carried out by Alfred Kamenobrodsky's firm, carpentry by Wczelak Brothers, varnishing by Alexander Boyarsky and interior design of six new classrooms by Marcin Prugar and Son. A detailed description of equipment necessary for the newly built premises is given, which allows understanding what the lecture halls of the time looked like. It is pointed out that the construction of wings led to other changes in the arrangement of the territory, in particular, a cobblestone path was finally paved from the main building to the chemistry building located nearby. Based on the studied sources and literature, the author concludes that the extension of the premises of the University in the early 20th century was extremely necessary. The addition of two so-called «wings» to the main building, however, did not solve the problem of lack of classroom space, because some of the units were still in rented premises and the professors constantly asked for the construction of new buildings for the needs of Lviv Polytechnic.
Neighbor connections and contemporary groups in a closed society, in the city of Hajdudoroz
Authors: Sári Tamás
Published: December 2021

Hajdúdorog is a local closed society, so the religious separation, the Hajdú military past and the agricultural nature of the settlement provide a specific approach to ethnographic researches. In my doctoral research, which includes this article, family and neighborhood relations are analyzed in this settlement. The temporal focus of the research is the 1940s which is the earliest decade that can be researched with informants through interviews. This article pays attention to the neighborhood of Hajdúdorog and contemporary groups, so locality is a key concept. The research question concerns the content of the relationships. How did the relationships in the environment of the neighborhood and contemporary groups, manifest themselves in Hajdúdorog in the 1940s? How did the above features affect this? The research was carried out within the framework of the ethnographic discipline. The article first presents the well-known works of the Hungarian ethnographic literature on the topic and then analyzes the empirical data. I applied the ethnographic method used in social disciplines to obtain empirical data. During the field work, I did in-depth interviews in Hajdúdorog with locals, all older than 75 years. I reached the inteview subjects using the snowball method and the interviews took place in the interviewees’ homes. The article examines the neighboring and contemporary groups separately. Based on the results it can be stated, that in Hajdúdorog the neighborly relations were daily. The tenths, the former special administrative units of the city, were still strong influencing factors in the development of relations in both groups, even during the researched period. The content of the neighborly relations was reflected in smaller household transactions, rental of tools, participation in pigslaughters (disznóvágás), assistance in fieldworks, special folk pastimes (tanyázás) which resulted in more intense relationships than with family relatives. The result of a closed society is that there was a closer relationship between those who lived within one part of the settlement than between relatives who lived in different parts of the settlement. In line with the above, the article seeks to contribute to the researches connected to locality. The subject of the article fits into the sociological neighborhood research category, such as Tönnies and Redfield's research and also fits into the neighborhood research of the Hungarian ethnography, which was also a base for this research. This work hopes to ultimately expand the row of Hajdúdorog’s literature. For further view, the article can encourage research that deals with a more detailed comparison of the role of the neighborhood and the role of neighbors and relatives in Hajdúdorog during the period that was examined in this article.
Memorialization of the "liberators" in Transcarpathia during the period of preventive Sovietization (1944 – 1946)
Authors: Leno Pavlo
Published: December 2021

In 1944 – 1946, during the preventive Sovietization of Transcarpathian Ukraine, the local communist authorities initiated radical changes in its symbolic landscape in order to influence the collective memory of the population. The result of this policy was the appearance in the region in 1945 of monuments in honor of the Heroes of the Carpathians (soldiers of the Red Army), who died as a result of active hostilities in October 1944. Officially, the perpetuation of the memory of the fallen Red Army soldiers took place as a manifestation of the people's initiative of the local population in gratitude for the liberation from fascism, including from the “centuries-old Hungarian slavery”. However, archival materials and oral historical research prove that this process was an element of the traditional Soviet policy of memory, initiated by the command of the 4th Ukrainian Front. As a result, a number of memorial resolutions of the People's Council of Transcarpathian Ukraine were adopted in a short time. As a result, the graves of the Red Army were enlarged, fundraising was organized among the population, and the construction of monuments to the fallen liberators was started and successfully completed in all regional centers of the region. The peculiarity was that the installation of monuments in honor of the Heroes of the Carpathians took place long before the end of the Great Patriotic War / World War II, which was not observed in other territories of the Ukrainian SSR. One of the other paradoxes was that, so, the representatives of the Hungarian minority of the region demonstrated their appreciation for their "liberation from Hungarian domination".

The article outlines the basic theory, operation principle, peculiarities of electromagnetic processes, and circuit and design solutions of a fundamentally new three-phase magnetic-valve controllable reactor, which combines increased response speed with high-precision stabilization of the current reactive power value. The advisability of a monoblock design with all power elements of the device placed in one transformer-type tank is substantiated. An example of the design of a magnetic-valve controllable transformer-type reactor for a capacity of 25 Mvar, and rated voltage of 35 kV is given along with an analysis of the effectiveness of its three-year operation as part of the Petrovsk-Zabaikalskaya 220/110/35 kV digital substation. It is shown that a reactive power source based on a new magnetic-valve controllable reactor is able---in addition to its main function of optimizing reactive power flows between power supply centers and load nodes---to normalize the voltage quality in a three-phase network with a nonlinear asymmetrical load in terms of such indicators as compensation of slow deviations of the three-phase voltage, symmetry of line-to-line voltages, and elimination of their waveform distortion.
Narcoterrorismo e neoliberalismo: condicionamentos e (re) enquadramentos do conflito social colombiano
Authors: Dos Reis Nascimento Júnior Wanderley , Silva de Souza Rafaela Cristina
Published: December 2021

No presente artigo, propõe-se uma reflexão acerca da relação entre política externa e estratégias de desenvolvimento nacional no contexto de globalização econômica neoliberal. Buscar-se-á compreender a relação entre a internacionalização do conflito social armado colombiano, as condicionalidades externas e o projeto de desenvolvimento estabelecido. Conclui-se que o Plano Colômbia, sob assistência financeira e militar norte-americana, condicionou um modelo de desenvolvimento neoliberal respaldado por um projeto de militarização da sociedade ao qual os sucessivos governos deram continuidade. Por fim, reflete-se, ainda, acerca da relação intrínseca entre neoliberalismo e militarismo e suas implicações para um projeto de paz inclusivo e sustentável.

Authors: Ruan Xiaoyu , Zhang Jingting
Published: December 2021

Este artículo tiene por objetivo analizar la cooperación en salud entre China y Argentina ante la crisis sanitaria de la COVID-19 desde la perspectiva de la gobernanza multinivel. Se ha demostrado que los actores estatales y subestatales desempeñaron un papel dominante en la primera etapa cooperativa, mientras que los actores no estatales empezaron a jugar un rol cada vez más activo y significativo en la segunda etapa. Mediante la cooperación sanitaria entre ambas naciones, Argentina ha logrado superar algunos desafíos traídos por la pandemia y ha mejorado la capacidad de gobernanza en salud frente al coronavirus. Para encarar la segunda ola de epidemia, existe la necesidad de profundizar la cooperación sanitaria entre los dos países a múltiples niveles.
Desafíos alrededor de la construcción de un digesto general para la Universidad Nacional de La Plata
Authors: Clark Rafael
Published: December 2021

La Universidad Nacional de La Plata, en tanto ente público estatal, se encuentra alcanzada por sendas previsiones federales vinculadas con la publicidad de sus actos, algunas de ellas resultan obligaciones y otras cargas a las cuales queda supeditada la eficacia jurídica del acto de que se trate. En paralelo, las propias normas universitarias de diversas épocas y formalmente vigentes contienen directivas y criterios, generando la necesidad de un estudio que permita su armonización sobre la base de los principios generales que gobiernan la materia. De tal modo, un digesto general adecuadamente estructurado para la satisfacción de estas necesidades jurídicas y de gestión, se presenta como la herramienta adecuada para el problema en estudio. Sin perjuicio de lo cual, un análisis cuidadoso de la especial coyuntura en la que se encuentra la burocracia universitaria y la adecuada ponderación de sus capacidades, potencialidades y limitaciones, permitirá calibrar los alcances que deban pretenderse para que la herramienta resulte jurídicamente eficaz, al tiempo que eficiente iniciativa de gestión en la concreta situación universitaria.

Formalización del área de Comunicación Institucional del Colegio Nacional “Rafael Hernández”
Authors: Mainero María Grazia
Published: December 2021

La comunicación desempeña un rol estratégico en el entramado de relaciones que se generan en una organización en torno a la consecución de sus objetivos. Empoderar a todos los sujetos que la conforman, a todas las hablas desde un proceso comunicacional que defina una línea de acción que los incluya, solo es posible desde la convicción de que la comunicación debe mediar entre sus integrantes. 

Resulta evidente que una institución como el Colegio Nacional “Rafael Hernández” necesita de la participación activa de la totalidad de los actores que componen su comunidad educativa. La formalización de un área de Comunicación Institucional permitirá visibilizar a todas las voces así como dar cauce a las diversas esferas de la organización en pos de un objetivo común: ofrecer una enseñanza inclusiva y de calidad para una población estudiantil que se caracteriza por la heterogeneidad de quienes conviven hoy en sus aulas.
La experiencia de la virtualización de las actividades de la incubadora universitaria MINERVA-UNLP en el contexto del Covid-19
Authors: Márquez Gonzalo Javier
Published: December 2021

Con el advenimiento del Aislamiento Social, Preventivo y Obligatorio dictado en el mes de marzo del 2020 por el Gobierno Nacional, los argentinos comenzamos vivir un contexto inédito. Las consecuencias sanitarias, sociales y económicas no tardaron en llegar y las instituciones del Estado comenzaron a tomar medidas para morigerar la situación. La Universidad Nacional de La Plata no estuvo exenta y tomó cartas en el asunto, desarrollando una serie de estrategias que impactaron por su rápida respuesta. La Incubadora Minerva de Emprendimientos fue clave en la conexión con el sistema productivo regional y, a través de ella, se realizaron acciones para canalizar los diversos emprendimientos de muchos emprendedores, quienes querían aportar en el combate de la pandemia. En este sentido, se realizó las Convocatoria “Tu idea Suma”, en la que se presentaron 63 proyectos, la mayoría de los cuales fueron canalizados para que pudieran ser efectivos. Pensando en la realidad post pandemia, se convocó al concurso: “¿Cambio Climático = Pandemias?”, considerando que uno de los grandes problemas generadores de enfermedades peligrosas es la falta de cuidado del ambiente. Se readecuaron las actividades de internacionalización programadas, con el objetivo de potenciar las acciones futuras, tendientes a mitigar los efectos de esta crisis. Además, se trabajó en la articulación de las PyMEs y los emprendedores con las líneas de financiamiento que fue presentando la Secretaría de Producción del Gobierno Nacional. Estas medidas han formado parte substancial en la respuesta institucional.

A Corpus-based Contrastive Study on English and Chinese Semantic Prime happen and fasheng in Natural Semantic Metalanguage
Authors: Wang Yajun
Published: December 2021

This paper reports a corpus-based study on English and Chinese semantic prime happen and fasheng in Natural Semantic Metalanguage. With the aids of computer software Wordsmith 5.0 and SPSS19.0, we conducted a contrastive study on happen and fasheng based on a small English and Chinese comparable corpus constructed by ourselves. By extracting evidence from the corpus, the distribution of happen and fasheng, their syntactic patterns, their colligation types as well as their semantic prosody are identified and analyzed. We found that there is no significant difference between English semantic prime happen and its Chinese counterpart fasheng with respect to their distribution, their syntactic patterns, their colligations, and their semantic prosody. The results reveal that semantic prime happen is identical with its Chinese counterpart fasheng. Thus it provides an evidence to justify the premise of the Natural Semantic Metalanguage Theory.

Published: December 2021

Badania nad oceną tolerancji czterech odmian jęczmienia jarego (Conchita, Antek, Eunova, Westminster) na herbicydy z grupy fenoksykwasów (Chwastox Trio 540 SL i Gold 450 EC) wykonano w latach 2010–2012. Doświadczenia założono w okolicach Wrocławia, w dwóch miejscowościach charakteryzujących się odmiennymi warunkami glebowymi: 1) w Laskowicach na glebie płowej, 2) w Turowie na czarnej ziemi. Herbicyd Gold 450 EC zastosowany w fazie 4–5 liści jęczmienia jarego spowodował deformacje roślin wszystkich badanych odmian. Silniejsze uszkodzenia wystąpiły w doświadczeniu na glebie płowej. Herbicyd Gold 450 EC, aplikowany zarówno w fazie 4–5 liści, jak również pierwszego kolanka rośliny uprawnej spowodował istotne straty w plonie jęczmienia jarego odmiany Eunova rosnącego na glebie płowej. Środek Chwastox Trio 540 SL nie spowodował uszkodzeń jęczmienia jarego, jednak sporadycznie obniżył plonowanie odmian Conchita i Eunova na czarnej ziemi. Badane herbicydy, pomimo obserwowanych statystycznie udowodnionych różnic, nie wpłynęły ujemnie na jakość ziarna jęczmienia jarego. Silniejsza reakcja jęczmienia jarego wystąpiła w doświadczeniu na glebie płowej.
Impact of plant density on the canopy area index and weed infestation depending on different cultivars of winter oilseed rape (Brassica napus L., ssp. oleifera Metzg.)
Authors: RÓŻYŁO KRZYSZTOF , PAŁYS EDWARD
Published: December 2021

One way to increase the competitiveness of crop plants against weed infestation is to adjust crop density. Introduction of new (“semi-dwarf”) cultivars of winter oilseed rape triggers a need for research in this field. A two-factor experiment evaluated the effect of plant density and winter oilseed rape (WOSR) cultivars on the canopy architecture and weed infestation of a WOSR crop as well as on the correlation between these traits. During the 2010–2012 study period, the average plant density was 38.0; 29.4; and 22.9 plants m-2 (three row spacings were used: 33, 44, and 55 cm). The oilseed rape cultivars were as follows: conventional, hybrid and “semi-dwarf” hybrid. Experimental factors did not cause significant differences in the number of weeds and their mass. However, there was a clear trend of decreasing total number of weeds in the span of 33 cm spacing than in the 44 and 55 cm. Hybrid cultivar resulted in increasing of total number of weeds in comparison to the conventional one. The differences in the assimilation area of WOSR plants per unit of ground area were significant between row spacings until the end of the flowering stage and between cultivars until the flower bud development stage. During the growth stages from the beginning of flowering until the end of pod development significant negative correlations were found between the assimilation area and the number of weeds, while the correlations between the assimilation area and the weed weight were insignificant. Insignificant correlations also occurred between the number of oilseed rape plants per unit area and the mass of weeds. The results indicate the possibility of reducing the demand for seed sowing, without requiring additional costs for weed control.
Wpływ intensywności technologii uprawy na plonowanie różnych genotypów pszenicy ozimej
Authors: RACHOŃ LESZEK , SZUMIŁO GRZEGORZ , MACHAJ HALINA
Published: December 2021

W pracy określono wpływ intensywności technologii uprawy na plonowanie ozimych genotypów pszenicy zwyczajnej, twardej, orkisz i jednoziarnowej. Dwuczynnikowe doświadczenie polowe przeprowadzono w latach 2010–13 w Gospodarstwie Doświadczalnym Felin Uniwersytetu Przyrodniczego w Lublinie metodą bloków losowanych w 4 powtórzeniach. Pierwszym czynnikiem były 4 gatunki (podgatunki) pszenicy ozimej: pszenica zwyczajna (Triticum aestivum ssp. vulgare L.) – odmiana Tonacja, pszenica twarda (Triticum durum Desf.) – odmiana Komnata, pszenica orkisz (Triticum aestivum ssp. spelta (L.) Thell.) – odmiana Schwabenkorn, pszenica jednoziarnowa (Triticum monococcum L.) – PL 5003 (materiał siewny pozyskany z Krajowego Centrum Roślinnych Zasobów Genowych). Drugą zmienną były poziomy agrotechniki: przeciętny poziom agrotechniki: nawożenie mineralne (N – 70, P – 30,5, K – 99,6 kg ∙ ha-1), zaprawianie ziarna i zwalczanie chwastów; wysoki poziom agrotechniki: zwiększone nawożenie azotowe (N – 140, P – 30,5, K – 99,6 kg ∙ ha-1), zaprawianie ziarna, zwalczanie chwastów, 2 zabiegi przeciw chorobom, insektycyd i regulator wzrostu. Badane gatunki (podgatunki) pszenicy istotnie różniły się poziomem plonowania. Najwyższy plon wydała odmiana pszenicy zwyczajnej, Tonacja – 7,25 t∙ha-1. Istotnie niżej plonowały pozostałe gatunki: pszenica twarda (Komnata) – 4,19 t ∙ ha-1, pszenica orkisz (Schwabenkorn) – 3,87 t ∙ ha-1 oraz pszenica jednoziarnista – 2,33 t ∙ ha-1. Wykazano interakcję między badanymi gatunkami (podgatunkami) a poziomem intensyfikacji technologii uprawy. Pszenica zwyczajna i twarda reagowały istotnym wzrostem plonu ziarna przy wyższym poziomie agrotechniki, natomiast nie wykazano różnic w przypadku pszenicy orkisz i jednoziarnowej. Otrzymane wyniki potwierdzają przydatność tych gatunków (podgatunków) do uprawy w warunkach mniej intensywnych. Średnio, niezależnie od badanych pszenic, wyższy poziom agrotechniki spowodował istotny wzrost plonu ziarna, obsady kłosów, MTZ, liczby ziarn z kłosa i masy ziarn z kłosa oraz ograniczał wyleganie roślin.
Odłowy sprężykowatych z rodzaju Agriotes spp. przy użyciu pułapek feromonowych w celu sygnalizacji zagrożenia
Authors: JAKUBOWSKA MAGDALENA , BOCIANOWSKI JAN
Published: December 2021

Celem badań było określenie składu gatunkowego odłowionych chrząszczy Elateridae oraz ustalenie ich liczebności i dynamiki występowania za pomocą pułapek feromonowych. Badania przeprowadzono w latach 2011–2013 na uprawach ziemniaka, kukurydzy, buraka cukrowego i traw nasiennych, zlokalizowanych w województwach wielkopolskim i warmińsko-  -mazurskim. We wszystkich badanych stanowiskach stwierdzono występowanie Agriotes lineatus L. (osiewnik rolowiec), A. obscurus L. (osiewnik ciemny) i A. sputator L. (osiewnik skibowiec). Wyniki przeprowadzonej analizy wariancji wskazują na istotne statystycznie zróżnicowanie jedynie liczebności A. lineatus w poszczególnych latach badań. Średnio najwięcej osobników z tego gatunku zaobserwowano w pierwszym roku prowadzenia obserwacji (72,62), natomiast najmniej w 2012 – 18,5. Istotne statystycznie różnice w występowaniu chrząszczy w poszczególnych miesiącach zaobserwowano dla wszystkich gatunków oprócz A. obscurus. Skuteczność odławiania chrząszczy sprężykowatych z wykorzystaniem pułapek feromonowych w poszczególnych miejscowościach była zróżnicowana. Na efektywność ich odławiania w dużej mierze ma wpływ przebieg warunków pogodowych. Uzyskane wyniki pozwolą na doskonalenie metod prognozowania krótkoterminowego i długoterminowego na potrzeby integrowanej ochrony roślin przed szkodliwymi drutowcami.

Published: December 2021

Celem badań była charakterystyka fitocenoz ze związków Calthion palustris i Filipendulion ulmariae, występujących na wilgotnych użytkach zielonych w środkowej części doliny Wieprza oraz ocena warunków tych siedlisk. Badania fitosocjologiczne przeprowadzono metodą Braun-Blanqueta. Związek Calthion palustris reprezentowały: zbiorowisko Deschampsia caespitosa i zespół Cirsietum rivularis. Zbiorowisko Deschampsia caespitosa występowało na glebach mineralnych i mineralno-organicznych, o niskiej zawartości składników pokarmowych. Łąki porośnięte roślinnością zespołu Cirsietum rivularis były zwykle zlokalizowane we wtórnie zabagnionych fragmentach doliny. Płaty tego zespołu występowały w sąsiedztwie zespołów – Alopecuretum pratensis oraz Caricetum gracilis. Zespoły Valeriano-Filipenduletum i Lythro-Filipenduletum ulmariae (związek Filipendulion ulmariae) występowały rzadko i tworzyły małe płaty na ekstensywnych łąkach, zlokalizowanych na glebach organicznych. Tworzeniu ziołoroślowych fitocenoz sprzyjała także mała troska o stan urządzeń wodno-melioracyjnych oraz zaniechanie użytkowania niektórych łąk

The burden of oral cancer in Nigeria is largely under-reported. The available data on oral cancer etiology/risk factors, clinical features, disease burden, and literacy rate in Nigeria points towards a possible explosion in prevalence in the near future, which poses a serious public health concern. The general medical and dental practitioners (GMDPs) in Nigeria can salvage this looming problem through appropriate public health and clinical interventions. This narrative review article re-emphasizes the key roles of GMDPs towards oral cancer eradication in Nigeria. It also discusses oral cancer case definition, etiology, risk factors, and the epidemiological burden in the Nigerian context.

Published: December 2021

Vertical condensation of gutta-percha is one of the frequently used techniques of hermetic and three-dimensional obturation of root canal system which is one of the primary goals of endodontic tooth treatment. Techniques for filling root canals have been described since ancient Egypt and have undergone dynamic development in recent decades. The aim of the article is to analyze the technique of obturation of root canals using vertical condensation of guttapercha and to point out its benefits and pitfalls.

The poor-quality treatment of the tooth deteriorates its prognosis, function, and long-term survival in the oral cavity; thus, the hermetic obturation of the root canals is one of the most important pillars of the complex tooth treatment. Obturation of the root canals by vertical condensation of warm gutta-percha is nowadays considered in the correct indications as one of the most commonly used techniques in the excellent dental practices. Even though it is quite technologically challenging and time-consuming it enables to reach high level of predictability and clinical success. Currently, the obturation technique based on master gutta-percha cone combined with the calcium-silicate based sealer is emerging. However, long term results of clinical studies and follow-up are needed to make a significant improvement in the area of endodontics.
Stochastic Bioimpedance-Based Channel Model of the Human Body for Galvanic Coupling
Authors: Roopnarine Aaron , Rocke Sean A.
Published: December 2021

Human body communication (HBC) uses the human body as the channel to transfer data. Extensive work has been done to characterize the human body channel for different HBC techniques and scenarios. However, statistical channel bioimpedance characterisation of human body channels, particularly under dynamic conditions, remains relatively understudied. This paper develops a stochastic fading bioimpedance model for the human body channel using Monte Carlo simulations. Differential body segments were modelled as 2-port networks using ABCD parameters which are functions of bioimpedance based body parameters modelled as random variables. The channel was then modelled as the cascade of these random 2-port networks for different combinations of probability distribution functions (PDFs) assumed for the bioimpedance-based body parameters. The resultant distribution of the cascaded body segments varied for the different assumed bioimpedance based body parameter distributions and differential body segment sizes. However, considering the distribution names that demonstrated a best fit (in the top 3 PDF rankings) with highest frequency under the varying conditions, this paper recommends the distribution names: Generalized Pareto for phase distributions and Log-normal for magnitude distributions for each element in the overall cascaded random variable ABCD matrix.
Improved estimation of left ventricular volume from electric field modeling
Authors: Korn Leonie , Dahlmanns Stephan , Leonhardt Steffen , Walter Marian
Published: December 2021

Volume measurement is beneficial in left ventricular assist device (LVAD) therapy to quantify patient demand. In principle, an LVAD could provide a platform that allows bioimpedance measurements inside the ventricle without requiring additional implants. Conductance measured by the LVAD can then be used to estimate the ventricular radius, which can be applied to calculate ventricular volume. However, established methods that estimate radius from conductance require elaborate individual calibration or show low accuracy.

This study presents two analytical calculation methods to estimate left ventricular radius from conductance using electric field theory. These methods build on the established method of Wei, now considering the dielectric properties of muscle and background tissue, the refraction of the electric field at the blood-muscle boundary, and the changes of the electric field caused by the measurements.

The methods are validated in five glass containers of different radius. Additional bioimpedance measurements are performed in in-vitro models that replicate the left ventricle’s shape and conductive properties. The proposed analytical calculation methods estimate the radii of the containers and the in-vitro models with higher accuracy and precision than Wei’s method. The lead method performs excellently in glass cylinders over a wide range of radii (bias: 1.66%–2.48%, limits of agreement < 16.33%) without calibration to specific geometries.

Published: December 2021

Background

In the first months of 2020, the SARS-CoV-2 virus spread all over the world and numerous measures were adopted that had a strong impact on both personal and public life. This contribution explores changes in alcohol and tobacco use during the first months of the COVID-19 pandemic in Slovenia.

Methods

Self-reported changes in alcohol and tobacco use during the first few months of the Covid-19 pandemic were recorded in 495 Slovenian adults, as part of the European Alcohol Use and COVID-19 survey.

Results

About half of the Slovenian sample indicated that the frequency of drinking occasions did not change in the months after the pandemic’s outbreak, while the remainder stated either a decrease (26.0%) or an increase (24.2%). 23.1% reported a decrease and 17.3% an increase in the quantity of alcohol consumed per occasion. Respondents who reported that their overall alcohol consumption decreased were more likely to be male than female and more likely to be younger than middle-aged. Those who reported experiencing at least a substantial level of distress due to financial loss were at a four-times increased risk of reporting an increase in their alcohol consumption compared to individuals who reported no or only some financial distress. Of the 120 people reporting the use of tobacco, almost half indicated an increase in tobacco consumption within the previous month, and about 20% reported a decrease in use. The differences in the results between Slovenia and other European countries are small and the overall pattern suggests that the situation in Slovenia was comparable to other European countries.

Conclusion

As this pandemic continues to evolve, further monitoring is needed to identify the long-term effects of alcohol and tobacco use on public health in relation to the management of COVID-19.
The careful assessment tool for managing patients with medically unexplained symptoms – The experience of Slovenian family medicine trainees: A qualitative study
Authors: Ivetić Vojislav , Martinjak Špela , Maksuti Alem
Published: December 2021

Introduction

Primary care physicians use various tools and methods to identify medically unexplained symptoms (MUS). The main purpose of our study is to determine the views of Slovenian family medicine trainees (FMT) about using the “Careful Assessment” tool for managing patients with MUS.

Methods

A qualitative study using open survey questions focused on the experience of family medicine trainees in managing patients with MUS. The sample consisted of surveys from 184 family medicine trainees. These trainees analysed a total of 702 patients with MUS. Manual coding was used for quantitative content analysis.

Results

In the coding process, 49 codes were developed that included broader research fields about using the “Careful Assessment” tool for managing patients with MUS. The codes were grouped into four theoretically grounded, logical categories in accordance with the elaborated theoretical concept: multi-purpose utility; improved patient management; in-depth knowledge and new skills; and patient response.

Conclusion

The study demonstrated that, in the view of Slovenian FMT, the “Careful Assessment” tool has multi-purpose utility. The study showed that FMT felt that this tool helps them in systematic patient management. Their opinion is that it helps them establish a trusting relationship with patients, which is a precondition for providing further treatment.

Aim

Vitamin D (VitD) is involved in calcium and phosphate homeostasis, bone health, and normal functioning of the immune system. VitD status is monitored using serum 25-hydroxy-vitamin D (25(OH)D) as a biomarker. Serum 25(OH)D concentrations below 30 nmol/L indicate VitD deficiency and below 50 nmol/L indicate insufficiency. VitD can be synthesised endogenously in human skin when exposed to ultraviolet B (UVB) radiation. In the absence of sufficient UVB-light exposure, VitD intake becomes the main source of VitD, with a recommended daily intake of 20 μg. The aim of this study was to conduct a review and meta-analysis on the abovementioned topics, focusing on scientific studies in various Slovenian populations.

Methods

We conducted a systematic review and meta-analysis of published scientific papers, academic theses, or conference contributions reporting serum 25(OH)D status and VitD intake across various Slovenian populations. A search was carried out using Web of Science, Scopus, Medline, and the Slovenian library database.

Results

We identified 43 pertinent studies that addressed 25(OH)D status and 16 that addressed VitD intake. Serum 25(OH)D status was generally low across all populations, and notable seasonal variability was observed. VitD intakes were below 5 μg in all studies.

Conclusions

A general observation is that various population groups across Slovenia are at high risk of vitamin D insufficiency and deficiency, particularly during wintertime. Regarding vitamin D intake, all included studies reported daily intakes below the recommended level. We also identified key research gaps that need to be addressed to support further public health decision-making.
A Comparative Structural Analysis of Four Radiosonde Models
Authors: Hegyi Norbert , Jósvai János
Published: December 2021

In this study, we first performed a comprehensive structural analysis of four models of radiosondes (devices intended for use as the meteorological probe of a sounding balloon) manufactured by three different companies – Graw, Vaisala and Meteomodem. The radiosondes were disassembled for visual inspection and manual measurement, three-dimensional computed tomography images were taken of their inner structure, and the outer shapes of the radiosondes were scanned with a structured-light three-dimensional scanner. The structural properties of the radiosondes thus identified were then compared to one other, based on which the Meteomodem M10 was ranked as the least harmful in a potential collision. Next, the Meteomodem M10 radiosonde was used in collision tests with a heavy target and with a pumpkin model, in order to evaluate the possible damage caused by and to the radiosonde in different types of collisions.

Authors: Mihalik Tomáš , Šperka Adrián , Hrudkay Karol
Published: December 2021

Night urban transport in Slovakia is realized by public transport only in selected regional cities. In the long run, due to the increasingly available taxi services and the lack of connection between rail transport and night public transport, it has a declining share in passenger transport. A new operation proposal is necessary for the regional city of Žilina, which considers not only the factor of continuity, but also other factors, such as economical operation and travel expenses. The main task of the article is therefore to propose a more usable concept that will attract as many satisfied passengers as possible to this segment of public transport.
Driving Duration Difference in Road Freight Transport Between Vehicles Up to and Over 3.5 Tonnes
Authors: Beňuš Ján
Published: December 2021

Working conditions for drivers in the European Union and Slovakia are governed by European and National regulations. Regulations lay down rules on driving times, breaks and rest periods for drivers of lorries and buses to improve working conditions and road safety. There is no doubt that with increasing freight performance, the number of carriers and vehicles in the field of road freight transport is also increasing. Therefore, in connection with the current EU legislation, which aims to increase road safety, attention is paid to adopting regulations for all road haulage operators and carriers. The purpose of this paper is to show difference between road freight transport performed by vehicles up to 3,5 tonnes and vehicles transporting goods where the maximum permissible mass of the vehicle, including any trailer, or semi-trailer, exceeds 3,5 tonnes.
