This paper examines the gendered trait preferences for rice and their role in the adoption of improved rice varieties among men and women rice farmers in Ghana. Four hundred rice farm households and 261 consumers were surveyed across 20 communities using a simple random sampling technique. Kendall’s coefficient of concordance, Tobit, and the multivariate probit regressions were used in the analyses. The results show differences in preferences for cooking quality traits and postharvest traits among men and women farmers. There was also a gender differential in the intensity of purchasing rice among men and women consumers. The results show that rice farmers’ decisions to adopt any of the four varieties—AGRA rice, Jasmine, Togo Marshall, or Amankwatia—are influenced by age, being married or indigenous, years of schooling, off-farm activities, farming experience, household size, farm size, FBO membership, extension contact, market proximity, and access to credit. To improve the rice value chain in Ghana, rice breeding efforts should consider varieties with trait preferences such as being tolerant of pest and diseases, aromatic, early maturing, and tolerance to shattering. However, to enhance the consumption of improved rice varieties, breeding efforts should target varieties that are aromatic, good textured, and have medium-sized grains for female consumers, while for male consumers preferred varieties would be less easily broken, white grain color, translucent, and with short cooking time.

Published: March 2023

This study evaluated the performance of a downflow hanging sponge (DHS) in reducing the concentrations of chemical oxygen demand (COD), ammonia (NH3), total suspended solids (TSS), and total dissolved solids (TDS) in high-strength organic wastewater (HSOW). The DHS unit was composed of three segments connected vertically and operated under different organic loading rates (OLRs) between 3.01 and 12.33 kg COD/m3sponge/d at a constant hydraulic retention time (HRT) of 3.6 h. The results demonstrated that the DHS system achieved COD, NH3, TSS, and TDS removal efficiencies of 88.34 ± 6.53%, 64.38 ± 4.37%, 88.13 ± 5.42%, and 20.83 ± 1.78% at an OLR of 3.01 kg COD/m3sponge/d, respectively. These removal efficiencies significantly (p < 0.05) dropped to 76.39 ± 6.58%, 36.59 ± 2.91%, 80.87 ± 5.71%, and 14.20 ± 1.07%, respectively, by increasing the OLR to 12.33 kg COD/m3sponge/d. The variation in COD experimental data was well described by the first-order (R2 = 0.927) and modified Stover–Kincannon models (R2 = 0.999), providing an organics removal constant (K1) = 27.39 1/d, a saturation value constant (KB) = 83.81 g/L/d, and a maximum utilization rate constant (Umax) = 76.92 g/L/d. Adding another DHS reactor in a secondary phase improved the final effluent quality, complying with most environmental regulation criteria except those related to TDS concentrations. Treating HSOW with two sequential DHS reactors was economically feasible, with total energy consumption of 0.14 kWh/m3 and an operating cost of about 7.07 USD/m3. Accordingly, using dual DHS/DHS units to remove organics and nitrogen pollutants from HSOW would be a promising and cost-efficient strategy. However, a tertiary treatment phase could be required to reduce the TDS concentrations.

Published: March 2023

Disasters such as earthquakes, droughts, floods, and volcanoes adversely affect human lives and valuable resources. Therefore, various response systems have been designed, which assist in mitigating the impact of disasters and facilitating relief activities in the aftermath of a disaster. These response systems require timely and accurate information about affected areas. In recent years, social media has provided access to high-volume real-time data, which can be used for advanced solutions to numerous problems, including disasters. Social-media data combines two modalities (text and associated images), and this information can be used to detect disasters, such as floods. This paper proposes an ensemble learning-based Deep Social Media Data Classification (DeepSDC) approach for social-media flood-event classification. The proposed algorithm uses datasets from Twitter to detect the flooding event. The Deep Social Media Data Classification (DeepSDC) uses a two-staged ensemble-learning approach which combines separate models for textual and visual data. These models obtain diverse information from the text and images and combine the information using an ensemble-learning approach. Additionally, DeepSDC utilizes different augmentation, upsampling and downsampling techniques to tackle the class-imbalance challenge. The performance of the proposed algorithm is assessed on three publically available flood-detection datasets. The experimental results show that the proposed DeepSDC is able to produce superior performance when compared with several state-of-the-art algorithms. For the three datasets, FRMT, FCSM and DIRSM, the proposed approach produced F1 scores of 46.52, 92.87, and 92.65, respectively. The mean average precision (MAP@480) of 91.29 and 98.94 were obtained on textual and a combination of textual and visual data, respectively.

Published: March 2023

Detecting asbestos-containing roofs has been of great interest in the past few years as the substance negatively affects human health and the environment. Different remote sensing data have been successfully used for this purpose. However, RGB and thermal data have yet to be investigated. This study aims to investigate the classification of asbestos-containing roofs using RGB and airborne thermal data and state-of-the-art machine learning (ML) classification techniques. With the rapid development of ML reflected in this study, we evaluate three classifiers: Random Forest (RF), Support Vector Machine (SVM), and eXtreme Gradient Boosting (XGBoost). We have used several image enhancement techniques to produce additional bands to improve the classification results. For feature selection, we used the Boruta technique; based on the results, we have constructed four different variations of the dataset. The results showed that the most important features for asbestos-containing roof detection were the investigated spectral indices in this study. From a ML point of view, SVM outperformed RF and XGBoost in the dataset using only the spectral indices, with a balanced accuracy of 0.93. Our results showed that RGB bands could produce as accurate results as the multispectral and hyperspectral data with the addition of spectral indices.

Published: March 2023

Extensive soft-rock floor heave in gob-side entry retaining considerably restricts the efficient and sustainable production of the mine. The mechanical capacities of roadway roof and floor strata are discussed through laboratory tests by taking the N2301 fully caving surface auxiliary transport gate road of the Ancient City Coal Mine in the Lu’an Mining Area of Shanxi Province as an engineering background. The stress distribution law of gob-side entry in mining the working surface was explored based on numerical simulation. After that, the mechanical mechanism of floor heave was studied through theoretical analysis. High lead abutment pressure and horizontal stress were superimposed in front of the working surface to cause soft-rock floor heave. The bulk weight of the high overburden was unevenly transmitted to the two sides because of the roof cantilever structure of entry retaining in the rear of the working face. The roadway floor produced an asymmetric sliding force, which caused the occurrence of floor heave. The control technology of floor heave combining the pressure relief of floor blasting and roof cutting was proposed taking account of the mechanism of floor heave. Then, the stress environment of the surrounding rock was improved by the deep hole blasting of the floor. Gob-side roof cutting was used to reduce impact of the bulk weight of the overburden on the surrounding rock deformation of the roadway. A test was conducted after verifying the control effect of blasting pressure relief on roadway floor heave through a similar simulation. Field tests indicated that the maximum floor heave was 168 mm at 250 m in the rear of the working surface, and floor heave was controlled. This study offers a more scientifically sound theoretical reference for controlling floor heave in gob-side entry retaining, which can significantly advance the sustainable development of gob-side entry retaining technology in coal mining.

Published: March 2023

The present study has been carried out to analyze the seasonal variation of the Urban Heat and Cool Island over the nine developing cities of India. The magnitude of urban heat/cool island and vegetation gradient (∆NDVI) were measured from the daytime satellite datasets. Results of this study show that during the pre-monsoon (March to May) season, the maximum magnitude of the Surface Urban Heat Island (SUHI) was experienced over Kolhapur city, whereas, in the winter, the highest intensity of SUHI was noticed over Pune city. Subsequently, outcomes also depict that the changes in ∆NDVI restrain the pre-monsoon means and the seasonal alterations in SUHI magnitude. However, during the winter (November to February) season, it is controlled by the temperature–vegetation conditions of the rural areas. For pre-monsoon and seasonal changes in SUHI, with the aid of ∆NDVI and the surface temperature of the urban area, regression equations were fitted for pre-monsoon and seasonal changes in SUHI, which explains nearly 90% of SUHI variation. Similarly, the variation of SUHI has been modeled for winter, which elucidates up to 84% of SUHI discrepancy. The study reveals that, on a seasonal scale, a decrement of 0.1 in seasonal ∆NDVI leads to an increase in the seasonal intensity of SUHI by 1.74 °C, which is quite a significant augmentation.

Published: March 2023

The molecular structure of the type 1 human immunodeficiency virus (HIV-1) is tightly linked to the mechanism of viral entry. The spike envelope (Env) glycoproteins and their interaction with the underlying matrix (MA) shell have emerged as key components of the entry mechanism. Microscopy evidence suggests that the MA shell does not span the entire inner lipid surface of the virus, producing a region of the virus that completely lacks an MA shell. Interestingly, evidence also suggests that Env proteins cluster during viral maturation and, thus, it is likely that this event takes place in the region of the virus that lacks an MA shell. We have previously called this part of the virus a fusion hub to highlight its importance during viral entry. While the structure of the MA shell is in contention due to the unaddressed inconsistencies between its reported hexagonal arrangement and the physical plausibility of such a structure, it is possible that a limited number of MA hexagons could form. In this study, we measured the size of the fusion hub by analysing the cryo-EM maps of eight HIV-1 particles and measured the size of the MA shell gap to be 66.3 nm ± 15.0 nm. We also validated the feasibility of the hexagonal MA shell arrangement in six reported structures and determined the plausible components of these structures that do not violate geometrical limitations. We also examined the cytosolic domain of Env proteins and discovered a possible interaction between adjacent Env proteins that could explain the stability of cluster formation. We present an updated HIV-1 model and postulate novel roles of the MA shell and Env structure.

Sacbrood virus (SBV) infection has emerged as a remarkable threat to Apis cerana colonies in South Korea, necessitating prompt control measures. In this study, RNA interference (RNAi) targeting the VP3 gene was developed to assess its safety and efficacy in protecting and treating SBV in vitro and in infected colonies in South Korean apiaries. The efficacy of VP3 double-stranded RNA (dsRNA) was demonstrated in laboratory-based experiments, wherein infected larvae treated with VP3 dsRNA exhibited a 32.7% increase in survival rate compared to untreated larvae. Data from a large-scale field trial indicate the efficacy of dsRNA treatment since none of the treated colonies had symptomatic SBV infections, whereas disease was observed in 43% (3/7) of the control colonies. In the 102 colonies exhibiting symptoms of SBV disease, RNAi treatment provided partial protection with weekly treatment, prolonging the survival period of colonies to 8 months compared to 2 months in colonies treated at 2- and 4-week intervals. Therefore, this study demonstrated that RNAi is a valuable tool for preventing SBV disease outbreaks in healthy and low-level SBV-infected colonies.

Published: March 2023

Mpox, formerly called monkeypox, is now the most serious orthopoxvirus (OPXV) infection in humans. This zoonotic disease has been gradually re-emerging in humans with an increasing frequency of cases found in endemic areas, as well as an escalating frequency and size of epidemics outside of endemic areas in Africa. Currently, the largest known mpox epidemic is spreading throughout the world, with over 85,650 cases to date, mostly in Europe and North America. These increased endemic cases and epidemics are likely driven primarily by decreasing global immunity to OPXVs, along with other possible causes. The current unprecedented global outbreak of mpox has demonstrated higher numbers of human cases and greater human-to-human transmission than previously documented, necessitating an urgent need to better understand this disease in humans and animals. Monkeypox virus (MPXV) infections in animals, both naturally occurring and experimental, have provided critical information about the routes of transmission; the viral pathogenicity factors; the methods of control, such as vaccination and antivirals; the disease ecology in reservoir host species; and the conservation impacts on wildlife species. This review briefly described the epidemiology and transmission of MPXV between animals and humans and summarizes past studies on the ecology of MPXV in wild animals and experimental studies in captive animal models, with a focus on how animal infections have informed knowledge concerning various aspects of this pathogen. Knowledge gaps were highlighted in areas where future research, both in captive and free-ranging animals, could inform efforts to understand and control this disease in both humans and animals.

COVID-19-related mortality among hematopoietic stem cell transplantation (HSCT) recipients in the pre-vaccine era ranged between 22 and 33%. The Pfizer/BioNTech BNT162b2 vaccine demonstrated significant immunogenicity and efficacy in the healthy population; however, its long-term effects on allogeneic HSCT recipients remained unclear. Our study longitudinally evaluated humoral and cellular responses to the BNT162b2 vaccine in adult allogeneic HSCT patients. A positive response was defined as antibody titers ≥ 150 AU/mL post-second vaccination. Among 77 included patients, 51 (66.2%) responded to vaccination. Response-associated factors were female gender, recent anti-CD20 therapy, and a longer interval between transplant and vaccination. Response rates reached 83.7% in patients vaccinated >12 months post-transplant. At 6 months post-second vaccination, antibody titers dropped, but were significantly increased with the booster dose. Moreover, 43% (6/14) of non-responders to the second vaccination acquired sufficient antibody titers after booster administration, resulting in an overall response rate of 79.5% for the entire cohort. The BNT162b2 vaccine was effective in allogeneic transplant recipients. Although antibody titers decreased with time, the third vaccination led to their significant elevation, with 93% of third-dose responders maintaining titers above 150 AU/mL at 3 months post-administration.

Published: March 2023

Background: It is important to evaluate the attitude of society towards vaccines to understand the rates of acceptance and hesitance towards vaccination, which are essential components of public health and epidemiology. This study aimed to evaluate the perspective of the Turkish population on COVID-19 status, rate of vaccination, and also to evaluate the reasons for refusal to vaccinate, vaccine hesitancy, and related factors. Methods: A total of 4539 participants were included in this population-based descriptive and cross-sectional study. The Nomenclature of Territorial Units for Statistics (NUTS-II) was used to obtain a representative sample and for this purpose Turkey was divided into 26 regions. Participants were randomly selected based on the demographic features and population ratios of the selected regions. The following parameters were evaluated: sociodemographic characteristics and perspectives on COVID-19 vaccines, Vaccine Hesitancy Scale Adapted to Pandemics (VHS-P), and Anti-Vaccine Scale-Long Form (AVS-LF) questions. Results: A total of 4539 participants, 2303 (50.7%) male and 2236 (49.3%) female, aged between 18 and 73 years, were included in this study. It was observed that 58.4% of the participants had hesitations towards COVID-19 vaccination, and 19.6% were hesitant about all childhood vaccinations. Those who did not have the COVID-19 vaccine, who did not think that the COVID-19 vaccine was protective, and who had hesitation to vaccinate against COVID-19 had significantly higher median scores on the VHS-P and AVS-LF scales, respectively (all p < 0.01). Those who did not have their children vaccinated in childhood and who were hesitant about childhood vaccinations, had significantly higher median scores on the VHS-P and AVS-LF scales, respectively (all p < 0.01). Conclusion: Although the rate of vaccination for COVID-19 was 93.4% in the study, hesitation to vaccinate was 58.4%. The median score of the scales of those who were hesitant about childhood vaccinations was higher than individuals who did not have any hesitation. In general, the source of concerns about vaccines should be clearly seen, and precautions should be taken.
The Impact of Charging Infrastructure on Local Emissions of Nitrogen Oxides
Authors: Hager Karsten , Graf Alexandra
Published: March 2023

Benefits from EV (Electric vehicles) and e-mobility include the reduction of local emissions of pollutants from particulate matter (PM0.5, PM5, and PM10) and nitrogen oxides (NOx and NO2). Cities and urban agglomerations benefit the most from potential emission reductions from EVs due to the large number of cars utilized in most urban traffic systems. This abstract presents results from a corporate research and funding project in Baden-Wuerttemberg, Germany (LINOx BW) which facilitates the installation of 2358 charging points within 178 different sub-projects in 23 different cities, spanning a period of four years. Utilizing several different survey waves, data about outgoing currents from these publicly funded charging points are gathered. Converting this data utilizing car classifications and emission classes (HBEFA), the reduction of local nitrogen oxides is derived.

Cardiovascular disease (CVD) is the main cause of death in patients with diabetes mellitus (DM). Cardiovascular risk in patients with type 2 diabetes is 2–4 times higher, and CVD occurs 15 years earlier than in people without diabetes. Timely detection and effective control of risk factors are of decisive importance for the prevention of complications of type 2 diabetes. The aim of the study: to identify cardiovascular risk factors and analyze the effectiveness of their control in patients with type 2 DM and diabetic foot syndrome (DFS). Material and methods. 80 patients with type 2 diabetes without associated CVD. Mean age 64.6 ± 9.2 years. The duration of type 2 diabetes was 10.0 (4.0; 15.0) years. Conducted a clinical examination, laboratory (clinical and biochemical blood tests) and instrumental (electrocardiography, ultrasound of the brachiocephalic arteries and arteries of the lower extremities, echocardiography, volumetric sphygmography) studies. Results. The frequency of detection of hypertension was 98.8%, dyslipidemia 91.0%. Target values of blood pressure (BP) were noted in 32.0%, and target values of low-density lipoprotein cholesterol (LDL-C) in 26.0% of the examined. 80.0% of patients received antihypertensive therapy, and 39.7% of patients received lipid-lowering therapy. Metformin was the most commonly prescribed oral hypoglycemic drug in the structure of drug therapy for type 2 diabetes. Insulin was significantly more frequently prescribed to patients with DFS. The target level of glycated hemoglobin (HbA1c) was observed in 55.0% of patients. Patients with DFS had significantly higher systolic and pulse BP, and reached the target BP values three times less often. Conclusion. Patients with type 2 diabetes are characterized by insufficiently effective control of glycemia and major cardiovascular risk factors. Thus, the target HbA1c levels were noted in every second patient, the target BP level in every third patient, and the target values of LDL-C only in every fourth patient.

Published: March 2023

B vitamins deserve special attention because they take an active part in the regulation of almost all systems activity, have a neurotropic effect. Among all B vitamins, the most actively used are B1 (thiamine), B6 (pyridoxine), B12 (cobalamin), which are prescribed both in monotherapy and in combination, intramuscularly or orally. Other B vitamins are rarely used alone, only in combination with other vitamins or biologically active supplements (dietary supplements). Thiamine is responsible for the metabolism of nerve tissues, the production of acetylcholine, which participates in carbohydrate metabolism and related energy, fat, protein, water-salt metabolism, has a regulating effect on trophism and the activity of the nervous system. Different forms of vitamin B1 (thiamine disulfide, thiamine hydrochloride, benfotiamine) have an analgesic effect, exhibit an antitumor effect. Pyridoxine exhibits an antioxidant effect, its phosphorylated form (pyridoxal phosphate) participates in the decarboxylation of amino acids, in the formation of physiologically active amines (adrenaline, serotonin, dopamine, tyramine). Polyneuropathy (PNP) of various genesis (diabetic, alcoholic, dysmetabolic) is a target for pyridoxine. Cobalamin is required as a co-factor of the cytosolic methionine synthase reaction and the mitochondrial methymalonyl-CoA mutase reaction. Vitamin B12 deficiency can be manifested by disorders in the hematopoiesis system, PNP, cognitive disorders. Other B vitamins are actively involved in metabolic processes: B2 (riboflavin) is used by the body to metabolize fats, proteins and carbohydrates into glucose for energy, participates in redox processes, the production of red blood cells, B3 (niacin) participates in the processes of anabolism and catabolism, B4 (choline) is necessary for the synthesis of acetylcholine, betaine and phospholipids, B5 (pantothenate) necessary for the synthesis of co-enzyme A, with a deficiency of which severe damage to the basal ganglia region develops, accompanied by progressive cognitive and motor disorders, B7 (biotin), B8 (inositol), B9 (folic acid), B10 (paraaminobenzoic acid) are necessary for normal body functioning. With a combined deficiency of vitamins B1, B2, B6 and B12, there is an increased risk of depression. In the treatment of diseases associated with B vitamins deficiency, a complex of vitamins should be prescribed to enhance the effect.
Challenges, threats and risks of formation of national economic security: global and national level

Published: March 2023

The article analyzes the modern approaches of scientists to defining the essence of such categories as “challenge”, “threat”, “risk” in the context of the national economic security formation. The author built the plane of interaction of a complex network of events in the security environment based on the relationships formed in the global environment. Global risks were analyzed from the point of view of their main characteristics (by levels of occurrence and spread, by groups, by probability of occurrence; by duration of existence; by degree of prevention and/or overcoming of negative consequences). The analysis shows that in recent years environmental risks, such as extreme weather fluctuations, environmental and natural disasters, and the risk of biodiversity loss, have become the most probable in terms of occurrence, level of impact, and difficulty to prevent. At the same time, it should be emphasized that for a long time the world community considered the most influential risks that depended directly on humanity (economic and geopolitical crises), recently, those that humanity cannot control (climate, natural elements, nature) are considered the most important. Among the significant short- and medium-term threats are also technological risks, including “digital inequality” and cybersecurity issues. At the same time, the likelihood of an aggravation of economic confrontation and internal political polarization remains, and due to the weakening of economic growth and the growth of financial inequality, the risk of economic stagnation increases. The author substantiates that the challenges, threats and risks of economic security are interconnected, mutually determining components of the national security environment, which under the conditions of all-encompassing globalization are difficult to divide by levels (global or national), they are rather complex in nature. Despite the non-local nature of the emergence of challenges, threats and risks, they cannot be considered by state governments in isolation and in many cases require close international cooperation.
GENRE ORIGINALITY OF OLES ULIANENKO'S WORKS
Authors: SHTEINBUK Feliks , GORDIIENKO Yulia
Published: March 2023

The work of Oles Ulianenko, a laureate of the Small Shevchenko Prize, poses quite a problem for Ukrainian literary studies for several reasons.

In the first place, it should be noted that the topics and stylistic features of the artist's works have been issues of polemic – also, there has been much disputation on the genre identification of O. Ulianenko’s novels, since, even in terms of number, he wrote relatively fewer of them than short stories and novellas.

Given that, the purpose of the article is to characterize and define the genre features of the writer's work, basing on the analysis of the novelette, novella, and novel prose of Oles Ulianenko.

The methodological foundation of the research consists mainly of a triad of methods, such as hermeneutic, comparative-typological and corporal-mimetic methods to analyze artistic works.

Thus, the findings of the research are as follows: Oles Ulianenko's novels, in various ways, demonstrate the presence of fundamental and antinomic novel and at the same time corporally determined factors, such as the categories of “(in) completion” and “development” in the content.

The proposed interpretation of the genre specificity of O. Ulianenko's works avoids both the previous and subsequent unproductive discussions regarding the belonging of the listed texts to the respective genres, i.e. short story, novelette, novella, and novel.

Accordingly, it becomes quite clear that the realization of Oles Ulianenko's artistic aspirations, besides his attempts to achieve the corresponding unattainable goal, which is focused on desperate efforts aimed at penetrating the ontological foundations of human existence, above all, corporally conditioned existence, are only possible (attempts) through the medium of a single genre mainly, namely the genre of the novel.

To conclude, the genre specificity of Oles Ulianenko's novels is the fact that, first, they neglect quantitative factors, second, they are justified by the author's involvement in the corporal-anthropological foundation of ontological problematique, and, in this regard, third, they are determined by the writer's efforts to overcome limitations of human existence through the infinity of life and literature, likewise the contradictions of man – through the obviousness of meager simplicity and corporal fragility, which, after all, explain and condition each other in many ways.

El uso de insecticidas en la agricultura representa un riesgo para la supervivencia de Apis mellifera, especie clave para mantener la biodiversidad del planeta. Un mecanismo para contrarrestar los efectos negativos es el desarrollo de colonias de abejas tolerantes a los neonicotinoides. El objetivo de este estudio fue determinar, mediante el cálculo de la dosis letal media (DL50), estimada mediante la regresión de mortalidad sobre dosis, las diferencias en la mortalidad de siete colonias de A. mellifera, tomadas al azar del apiario experimental del Colegio de Postgraduados, Campus Montecillo, México. Las colonias fueron expuestas a cuatro dosis (0.033-1.0 mL L-1) del insecticida Confidor® (i.a., imidacloprid 30.2 %) y a un coadyuvante comercial (DAP Plus®). Se registró durante 72 h la mortalidad de las abejas. La DL50 fue variable entre colonias. La dosis superior del insecticida, correspondiente a la recomendación del fabricante (1.0 mL L-1), resultó altamente letal (75.1 %). Se identificó una colonia que mostró mayor tolerancia, con menor porcentaje promedio de mortalidad (26.3 %).

Published: March 2023

In building constructions, considering sustainability, there is an increased interest in a reduction in landfills, converting waste materials into nanomaterials by using for example waste materials like waste grain wheat, waste ceramic, and slag, decreasing thus also the price of production of concrete and enhancing the properties of construction products. This article will focus on using waste ceramic powder and blast furnace slag as replacements for cementitious materials. “Conventional concrete” (Cc) is produced by mixing 100% cement + sand + water whilst “Sustainable concrete” (Sc) is produced from a mix of sand + water + 47.5 % cement+ 50% of waste-based Supplementary Cementitious Materials (SCMs) consisting of 25 % of Waste Ceramic Powder (WCP) and 25% of Blast Furnace Slag (BFS) ) +2.5% of nano SiO2. This article makes an economic comparison between these two types of concrete, showing that whilst the cost of 1 m3 Cc is approximately 100 $, the cost of 1 m3 Sc is 60 $, having the same mechanical properties. By using Sc for construction works leads to saving huge quantities of raw material used for cement production. The economic evaluation showed savings in cost around 40% by partial substitution of cement with waste-based/reused cementitious materials, being a promising result for a sustainable construction industry.

A migráció egyidős az emberiség történetével, és történelmi korszakonként különböző intenzitással kerül a figyelem középpontjába ez a demográfiai folyamat. Az utóbbi évtizedben szakmai és közéleti szempontból is felértékelődött a migrációs folyamatokról szóló diskurzus. A téma szakértői számára mindig nagy kihívást jelent a ki- és bevándorlók számának meghatározása, valamint a rendelkezésre álló adatbázisok alapján megfelelő becslési eljárások kidolgozása. A tanulmányban a vándorlási statisztikák történetének bemutatása mellett kitérek a felhasználható adatbázisok által nyújtott lehetőségekre, illetve azok korlátaira. A nemzetközi vándorlás mérhetőségével kapcsolatban az elmúlt évtizedben több nehézség merült fel Magyarországon, ezek ellensúlyozására új kutatási projektek indultak, amelyek rövid áttekintésére is sor kerül.

Authors: Balázs László , Kőkuti Tamás
Published: March 2023

A szervezetek humánerőforrás adottságaival kapcsolatosan az egyik legtöbbet vizsgált témakör a munkaértékek rejtett preferenciáinak, struktúrájának feltárása. A munka világában a munkaerőpiac kínálat-keresleti viszonyaitól is függően gyakran változnak a preferenciák. Tanulmányunk a munkaértékek lehetséges preferencia tényezőire koncentrál. Bemutatjuk a munkaérték fogalmi körét, majd egy a témakörben végzett vizsgálatot. A kutatás mintáját a szállítási ágazatban dolgozó Nyugat-dunántúli és Észak-alföldi régió munkavállalói alkották. A vizsgálat aktualitását a szektorban bekövetkező lehetséges foglalkoztatási változások adták. A felmérés kiterjedt arra is, hogy a két feltárt régióban a vizsgálati körbe bevont munkavállalók preferenciáiban milyen eltérések mutatkoztak.

Published: March 2023

A kortárs városkutatás előszeretettel foglalkozik a különböző felsőoktatási intézmények városi környezetre gyakorolt közvetlen, illetve közvetett hatásaival. Ezek a sokrétű, komplex hatások aktívan alakíthatják a városszövetet, a városi teret, továbbá jelentékeny hatást fejtenek ki többek között a környezetükben található szolgáltatásokra, az ingatlanpiacra, térhasználatra, az adott település vagy településrész gazdasági-társadalmi folyamataira, a turizmusra és nem utolsó sorban kulturális életére. Jelen előadásunkban Budapest XI. kerület, Lágymányos példáján keresztül mutatjuk be a studentifikáció erőteljes jelenlétét, valamint a kulturális és gasztroturizmus fejlődését az újbudai Bartók Béla út térségében, melyek együttes hatása jelentékeny szerepet játszik egy fenntarthatóbb, kisléptékű helyi turizmus létrejöttében a vizsgált területen. Kutatásunkat komplex, kvalitatív társadalomtudományos módszertanra építettük, melynek kiemelkedő fontosságú eleme a terepi, illesztve résztvevő megfigyelés, valamint a félig strukturált módszertannal készülő szakértői, illetve egyéb interjúk vendéglátóipari szereplőkkel.

Authors: Márkus Mónika
Published: March 2023

Kutatásomban a hazai kis-és középvállalati szektor hitelezési tendenciáit vizsgálom szem előtt tartva az elmúlt időszak krízis pontjait. Hiszen vállalkozások a 2008-as gazdasági világválságot követen épp hogy kezdtek gazdaságilag fellendülni, azonban 2020 márciusában újabb nehézséggel, a Covid-19 vírussal kellett szembenézniük. Mely számos vállalkozást pénzügyileg-gazdaságilag nehéz helyzetbe hozott. Ezen csapásból még ki sem lábalva 2022 év elején kitörő orosz-ukrán háború újabb akadályokat gördített a vállalatok, különösképpen a KKV-szektor szereplői elé. Vizsgálatom során a hazai KKV-k hitelpiaci lehetőségiet térképezem fel.
A cégértékelés módszertani kihívásai
Authors: Fábiánné Játékos Judit Ilona
Published: March 2023

Emlékeznek az 1987-ben bemutatott, mára legendássá vált Tőzsdecápák című film főbb jeleneteire, a technikákra, amellyel cégeket emelnek fel, vagy tesznek tönkre, vagy hogyan manipulálják a részvények értékét? Vajon ez csak egy film, vagy van ebben valamennyi igazság? Jelen cikkben arra keresem a választ mennyit ér egy vállalat, egyáltalán meghatározható-e a vállalat értéke? Meg lehet-e határozni, ha eladásra kerül egy társaság, vagy részvények kerülnek a piacra, a tőzsdére, hogy mi az az összeg, amely mindezekért kifizethető, és a piac által meghatározott ár azonos-e az értékkel? Léteznek-e tudományosan alátámasztott módszerek, amelyek segítségével az érték meghatározható? És ha igen, akkor milyen pontossággal tudják ezek valaminek az értékét alátámasztani? Konklúzióként elmondható, hogy a modern értékelési szemlélet a modern vállalati pénzügyek, a vállalati stratégiák és a tőkepiaci elméletek fejlődése nyomán alakult ki, és ebből következik, hogy a vállalatértékelés nem csupán számviteli, hanem komplex közgazdasági feladat, amely magas szintű pénzügyi és közgazdasági ismereteket igényel.

Published: March 2023

The tourism sector in Indonesia is considered a priority sector as in 2015, the tourism sector became the highest presentation in ASEAN for the contributor to the national Gross Domestic Product (GDP) constituting 10%. Based on the Long-Term National Tourist Development Plan for 2010-2025, the Indonesian government had been selected as many as 50 tourism destinations nationwide to be developed by 2025. Indonesia also has a broad diversity of cultural values to be the main tourist attraction. The optimism is raised as cultural-based tourism will continue to expand in the future. Cultural-based tourism could be seen as a local area development driver, although the human factor is still considered the key role. Knowledge, skills, motivations, and collaboration are the main factors. In addition, it is also important to highlight not individual offers, but the region as a whole connecting different tourism spots. Surakarta City offers several attractions for its tourism both tangible and intangible divided into different themes such as historical; cultural; natural, entertainment, and recreation; religious; handy craft art; transportation; shopping; and culinary. Regarding the potential possessed by the city, education tourists and individual mass tourists should be considered the most suitable target markets and additionally, the related tourism products and services to be applied aiming to support Indonesia's tourism planning.
Fenntartható design - új megközelítések a terméktervezésben
Authors: Nádas Gergely , Molnár László
Published: March 2023

Világunkat sorozatos válságok rázzák meg, melyek életünk minden területére kihatnak, az egészségügytől kezdve az energia kérdésén át egészen a mindennapok gazdasági kihívásainak leküzdéséig. A kialakuló új helyzetek új megközelítéseket és új megoldásokat kívánnak, melyek fókuszában a környezetet kímélő, könnyen újrahasznosítható alapanyagok és az energiatakarékos, költségkímélő technológiák állnak. Ebben a világméretű szemléletváltásban mind a termék tervezője és előállítója, mind a fogyasztó kölcsönösen érintett. Fontos feladat tehát megvizsgálni, hogy milyen területeken segíthetik egymást a hatékonyság növelésében és milyen eszközök és lehetőségek állnak a rendelkezésükre. Ebbe a folyamatba illeszkedik a hétköznapi termékekkel kapcsolatos fogyasztói preferencia kialakulásának vizsgálata, melynek segítségével tudatosabb, célorientáltabb termékfejlesztési és tervezési irányok jelölhetőek ki. Az elvégzett kísérletek alapján joggal gondolhatjuk, hogy érdemes többféle összefüggést keresni a formatervezett tárgyak plasztikai felépítése és a befogadók választása között.
Fiatal külföldi turisták pozitív és negatív tapasztalatai Budapesten
Authors: Grotte Judit , Magyar Tímea
Published: March 2023

Budapest, Magyarország fővárosa, természet- és ember alkotta vonzerejével, méltán vívta ki népszerűségét, a belföldi és külföldi utazók körében is. Jelen cikkünk a fiatal külföldi turisták szemszögéből mutatja be Budapest látnivalóit. Primer kutatásunkban félig strukturált interjú-elemzés segítségével mérjük fel a fiatal felnőtt korosztály utazási motivációit, központba helyezvén Budapestet, mint kiemelt turisztikai desztinációt. A felmérés során leginkább arra kerestük a választ, hogy a fiatal utazók mely faktorok mentén választják Budapestet, és mi alapján döntenek tartózkodási idejük hosszáról. A kutatás módszertanaként a fókuszcsoportos kvalitatív interjút választottuk, azért, mert jelen kutatási kérdéskört egy nagy kvantitatív kérdőív kialakításának előtanulmányaként tekintjük. A fókuszcsoportos kutatás a megkérdezettek véleménye alapján hat olyan területet azonosított, melyek a legtöbb pozitív élményt szerezték a fiatal külföldi turistáknak Budapesten: (1) emberek (helyiek kedvessége); (2) helyek, látnivalók (történelmi emlékek és különleges hangulat); (3) zöld övezet, levegő, tér; (4) szórakozási lehetőségek; (5) közlekedési infrastruktúra és közbiztonság; (6) gasztronómiai értékek.
Erdei biomassza lehetőségei és korlátai Magyarország energiabiztonságában
Authors: Vargovics Máté , Nagy Dániel
Published: March 2023

Jelen kutatás az energetikai célú erdei biomassza magyarországi helyzetét, kilátásait és kihívásait járja körül. A megújuló energiaforrások az utóbbi évtizedekben jelentősen felértékelődtek, és relevanciájuk tovább nőtt a közelmúlt válságos eseményeinek hatására. A dolgozat célja, hogy reális képet adjon az erdei biomassza energiaszektoron belüli szerepéről, bemutatva a hazai tűzifa termelés és felhasználás alakulását, valamint kitérjen a hozzá kapcsolódó uniós és hazai szakpolitika törekvésekre is. A kutatás során elsősorban az érintett szakmai háttérintézmények adataira támaszkodva vizsgáltuk az elmúlt évek trendjeit, különösen a tűzifa naturális és pénzügyi jellemzőire vonatkozóan. Az eredmények összességében arra engednek következtetni, hogy az erdei biomassza szerepe az energiaellátás terén továbbra is indokolt, azonban a felhasználási oldal várhatóan átalakul a jövőt tekintve, amire szükségszerű lesz valamennyi ágazati szereplőnek időben reagálnia.

The hand is an easy agent for the spread and transmission of pathogens and community-acquired infections. This study aims at evaluating the antimicrobial activity of Strombosia grandifolia hand sanitizer compared with a commercially available alcohol-based hand sanitizer. Water, methanol, and ethyl acetate extract from the leaf of Strombosia grandifolia was used to formulate hand sanitizer.  The antimicrobial activity of the hand sanitizers was carried out against Staphylococcus aureus, Pseudomonas aeruginosa, Escherichia coli, Bacillus subtilis and Candida albicans and analyzed with one-way ANOVA. The sanitizers were smooth with a chilly feel on the skin. Aqueous and methanol extract sanitizer had a significantly better antimicrobial activity when compared with ethyl acetate extract with the rank order of susceptibility of the microorganisms as Staphylococcus aureus > Bacillus subtilis > Pseudomonas aeruginosa > Escherichia coli > Candida albicans. The incorporation of the extract synergized the antimicrobial activity of alcohol-based hand sanitizers.

Published: March 2023

Backgrounds: To evaluate changes in the thickness of ganglion cell-inner plexiform layer and macular retinal nerve fiber layer using ocular coherence tomography in patients exposed to hydroxychloroquine .

Methods: This was a retrospective, cross-sectional study of patients on hydroxychloroquine therapy. Ocular coherence tomography images showing ganglion cell-inner plexiform cell layer and macular retinal nerve fiber layer thickness were obtained and compared to controls. The relationship between the thickness of ganglion cell-inner plexiform and macular  retinal nerve fiber layer, duration and cumulative dose of hydroxychloroquine were evaluated.

Results: In all, 219 subjects were included. The Thickness of the ganglion cell-inner plexiform thickness was significantly less than controls  (p = 0.006). The average  macular RNFL thickness was less in the study compared to the control groups, but not statistically significant (p = 0.389). There was no significant correlation between ganglionic cell-inner plexiform and macular retinal nerve fiber layer with duration, daily dose, or cumulative dose of hydroxychloroquine.

Conclusion: Thinning of the ganglionic cell- inner plexiform  layer could be an early indicator of retinal toxicity before the appearance of clinical retinopathy.
