Transformation of the Fiscal Mechanism of EU Member States and Ukraine During the Covid-19 Pandemic: from Consumption Supporting of to Investment Stimulation
Authors: Rudenko Viktoriia , Pohrishchuk Halyna , Moskvichova Olena , Bilyi Mykhailo
Published: June 2022

Faced with COVID-19, most countries have used the fiscal mechanism to mitigate the effects of the coronavirus crisis, which primarily involved supporting economic subjects and ensuring the required level of consumption. However, on the way to overcome the pandemic, it is necessary to use a fiscal mechanism to stimulate investment, which is an important prerequisite for economic recovery. Therefore, the purpose of the article is to determine the role of the fiscal mechanism in the context of the COVID-19 pandemic and justify its reorientation from supporting consumption to stimulating investment. In the course of the research, it was established that in modern conditions the fiscal mechanism acquires special significance, becoming a priority tool for the struggle of states against the consequences of the corona crisis, shifting the emphasis from the previous priority of the monetary mechanism. The impact of the fiscal mechanism in terms of budget revenues, budget expenditures, government loans, and guarantees on consumption and investment in EU member states and Ukraine were analyzed. As a result of the study, it was found that the COVID-19 pandemic, which has intensified all existing socio-economic problems of states, despite all its negatives, can become a springboard for qualitatively new investment development. At the same time, it is necessary not to change the design of the fiscal mechanism, but to reorient it to more efficient and adapted to new conditions investments in the development of green and digital economy, as well as strengthening the socio-economic stability of countries.

Adultizirano dijete rane i predškolske dobi u suvremenom konceptu odgoja i obrazovanja
Authors: Pintar Željka
Published: June 2022

U radu se tematizira slika suvremenog djeteta rane i predškolske dobi u kontekstu aktualne pedagoške paradigme. Suvremeno društvo, zainteresirano da znanjem unaprijedi svoj gospodarski sustav, upućuje specifičan interes odgoju i obrazovanju pojedinaca. Suvremeni pedagoški koncept društva znanja zasniva se na teoriji učenja – konstruktivizmu. U skladu s time, dijete je dominantno shvaćeno kao ono koje uči uspostavljajući pritom partnerske odnose s odraslima. Djetetu se upućuje specifična odgovornost za vlastitu razvojnu dobrobit, ono se adultizira. Suvremen pristup djetetu, koji se zasniva na sociološkom konceptu njegovih prava, zanemaruje stajališta psihološkog diskursa kojim se razmatraju njegove razvojne potrebe, što se posljedično reflektira na karakter suvremenog odgojnog odnosa i dovodi do krize odgoja. Ovim se radom razmatra specifičan utjecaj suvremenih pedagoških polazišta, poput primjerice onog o ravnopravnom partnerstvu djeteta i odgojitelja, djetetu kao autonomnom subjektu ili prostoru kao trećem odgojitelju, na pojedine aspekte razvoja adultizirano shvaćenog djeteta rane i predškolske dobi. Upućuje se na važnost pojmovnog redefiniranja, umjesto odbacivanja, koncepta odgoja kao središnjeg predmeta pedagogijske znanosti.

Social entrepreneurs play an important role in the economic and social development of the communities in which they operate. The career aspiration of social entrepreneurs can be encouraged if youths are given early educa-tional exposure when they are young. The purpose of this paper is to work out the proposal for study curriculum in order to include a subject of social entrepreneurship. To attain this aim, the following tasks were put forward: (1) to research literature regarding social entrepreneurship and social entrepreneurship education; (2) to describe the empiri-cal research methodology; (3) to discuss research results; (4) to propose a module for teaching social entrepreneurship to business students. These tasks account for the structure of the article: introduction, literature review, methodology, results and discussion, conclusions and recommendations. The theoretical basis of the current article consists of recent literature on the social entrepreneurship (taking into account Covid-19 circumstances), social entrepreneurship educa-tion, as well as of the legal documents of the Republic of Latvia. The empirical research is bipartite – first, a survey of business students, applying the snowball sampling method, using 5-point Likert scale questionnaire, second, a survey of business school lecturers. The results are interpreted using methods of descriptive and inferential statistics – mean ranking and Kruskal Wallis test. The results of the research have a practical value, as they identify the problematic areas of business education in regard to social entrepreneurship and make it possible to offer a practical solution – an insert module of social entrepreneurship.

Published: June 2022

Competitive advantages of retail companies in Lithuania becoming popular in XXI age. Competitive advan-tages of retail companies are becoming popular not only in small organisations with a small budget, but also big retail companies. This article was devoted to examining the literature related to competitive advantage and conducting an empirical study in a retail company. The literature reviewed shows that a competitive advantage is one that is difficult to copy for competitors. The problematic question is what are the competitive advantages of retail companies that are important in retail. Thus, the current situation causes a problem because the concept of competitive advantages of retail companies is not established in the scientific literature. Purpose is to investigate competitive advantage in retail mar-ket companies. Objectives of the study: to analyse the theoretical aspects of the concept of competitive advantages, to examine competitive advantages indicators, to survey competitive advantages in retail market company Lithuania. The paper relies on scientific literature analysis and survey research. The study encompasses theoretical literature analysis, survey as well as comparative analysis. Competitive advantage – this is called a strategic advantage, which must be such that it can be used for as long as possible. This advantage allows for higher-than-average revenues and strong market positions. It is important to mention that it is not acquired once and for all. It is almost always lost after a certain pe-riod of time. The Pearson chi-square test helps to assess the presence or absence of a statistical relationship between the indications studied. H1: Is there a relationship between a significant and meaningful link between the customer’s reputation and the company’s reputation? α – significance level chosen in this case 0.05. After calculating the Pearson’s correlation coefficient, it was found that the level of significance of the observation (p-level) = 0.047, where 0.047 < 0.05. It can be argued that there is a significant and meaningful link between the favourite customer feedback about the company and the company’s reputation. For a deeper analysis, Hypothesis H2 was tested by calculating the Pearson correlation coefficient, where α = 0.05. H2: there is a significant and meaningful connection between service – help, advice, fast and accurate information and level of security, guarantees. Calculations showed that the significance level of the observation (p-level) = 0.028, where 0.028 < 0.05.

Since the day of its explosion, supernova (SN) 1987A has been closely monitored to study its evolution and to detect its central compact relic. In fact, the formation of a neutron star is strongly supported by the detection of neutrinos from the SN. However, besides the detection in the Atacama Large Millimeter/submillimeter Array (ALMA) data of a feature that is compatible with the emission arising from a protopulsar wind nebula (PWN), the only hint of the existence of such an elusive compact object is provided by the detection of hard emission in NuSTAR data up to ∼20 keV. We report on the simultaneous analysis of multiepoch observations of SN 1987A performed with Chandra, XMM-Newton, and NuSTAR. We also compare the observations with a state-of-the-art three-dimensional magnetohydrodynamic simulation of SN 1987A. A heavily absorbed power law, consistent with the emission from a PWN embedded in the heart of SN 1987A, is needed to properly describe the high-energy part of the observed spectra. The spectral parameters of the best-fit power law are in agreement with the previous estimate, and exclude diffusive shock acceleration as a possible mechanism responsible for the observed nonthermal emission. The information extracted from our analysis is used to infer the physical characteristics of the pulsar and the broadband emission from its nebula, in agreement with the ALMA data. Analysis of the synthetic spectra also shows that, in the near future, the main contribution to the Fe K emission line will originate in the outermost shocked ejecta of SN 1987A.

Protostellar outflows and jets play a vital role in star formation as they carry away excess angular momentum from the inner disk surface, allowing the material to be transferred toward the central protostar. Theoretically, low-velocity and poorly collimated outflows appear from the beginning of the collapse at the first hydrostatic core (FHSC) stage. With growing protostellar core mass, high-density jets are launched, entraining an outflow from the infalling envelope. Until now, molecular jets have been observed at high velocity (≳100 km s−1) in early Class 0 protostars. We, for the first time, detect a dense molecular jet in SiO emission with low velocity (∼4.2 km s−1, deprojected ∼24 km s−1) from source G208.89–20.04Walma (hereafter G208Walma) using ALMA Band 6 observations. This object has some characteristics of FHSCs, such as a small outflow/jet velocity, extended 1.3 mm continuum emission, and N
2D+ line emission. Additional characteristics, however, are typical of early protostars: collimated outflow and SiO jet. The full extent of the outflow corresponds to a dynamical timescale of ∼

yr. The spectral energy distribution also suggests a very young source having an upper limit of T
bol ∼ 31 K and L
bol ∼ 0.8 L
⊙. We conclude that G208Walma is likely in the transition phase from FHSC to protostar, and the molecular jet has been launched within a few hundred years of initial collapse. Therefore, G208Walma may be the earliest object discovered in the protostellar phase with a molecular jet.
LTD064402+245919, Compact Binary or Subgiant with Red Star Eclipsing Binary?
Authors: Guo Jincheng , Liu Cheng
Published: June 2022

Recently, a single-line spectroscopic binary, LTD064402+245919, has been discovered by Yang et al. Using data from LAMOST and ZTF, the unseen companion is estimated to have a mass of 1–3 M
⊙, orbiting a subgiant with orbital period of 14.50 days, making it a good compact binary candidate without X-ray emission. However, new light curves from ZTF and ASAS-SN, has shown the depth of one dip increases toward a bluer wavelength, indicating LTD064402+245919 is more likely to be a subgaint with a red star. Using both Wilson–Devinney code and Phoebe, the derived T
eff of secondary is about 3400 K, corresponding to a red M2/3 star. Additionally, the 20% error of parallax from Gaia is large. The mass of subgiant will be 1.28 M
⊙ instead of 2.77 M
⊙, if the refined distance of 5.0 kpc is used. Nevertheless, new multi-color photometry are warranted for the final confirmation of binaries properties.

Introduction: Measles is among the most contagious and vaccine-preventable respiratory diseases. The aim of this research was to describe the socio-demographic profile, clinical manifestations and laboratory parameters of measles patients hospitalized at Kosovska Mitrovica Clinical Centre during the 2017−2019 outbreak.

Methodology: The prospective study included all patients that had contracted measles (107) who were hospitalized at Kosovska Mitrovica Clinical Centre during the outbreak. All complications that led to hospitalization were analyzed and the frequencies of complications with respect to patient age and vaccination status were recorded.

Results: More than half (51%) of the patients were unvaccinated. Patients’ age varied statistically significantly with respect to vaccination status. Pneumonia was noted in 65% of the patients from the younger age group, compared to 32% of adults, and this difference was statistically significant. Hepatitis was a significantly more frequent complication in adults, affecting 36% of measles patients in this age group, compared to only 7% of those aged below 18 years. In the unvaccinated group, 71% pneumonia frequency was noted, compared to 11% and 35% in the vaccinated and unknown vaccination status groups, respectively. The differences in frequencies based on vaccination status were statistically significant.

Conclusions: Most hospitalized patients were unvaccinated. Complications showed a significant difference with respect to the age and vaccination status of patients. Therefore, it is necessary to carry out continuous health promotion activities to raise awareness among the entire population of the importance and need for vaccination of children against measles, but also adults who have not been previously vaccinated.

Necrotizing fasciitis (NF) is an aggressive, necrotic, life-threatening infection of the soft tissues. The delay on treatment is generally accompanied by almost 90 % lethality according to the development of septic shock and its associated complications. Primary Necrotizing Fasciitis of the Breast (PNFB) is seen extremely rare. To date, breast necrotizing fasciitis have been reported only as a limited number of case reports in the literature. PNFB is commonly misdiagnosed as cellulitis, mastitis, abscess or inflammatory breast cancer. Although PNFB is a very rapid and aggressive disease, which can be fatal. Delayed cases were unfortunately resulted in mortality due to several consequential reasons. Therefore, careful and detailed evaluation of all cases irrespective of age, especially those with risk factors and comorbidities, could be life saving in respect of early diagnosis and timely treatment. Our aim is to to present the analysis and treatment modalities of five primarily seen PFNB, in this case series.
High Prevalence of Multi-drug Resistant Methicillin-Resistant Staphylococcus aureus in Tertiary Egyptian Hospitals
Authors: Alfeky Abdel-Aty E , Tawfick Mahmoud M , Ashour Mohamed S , El-Moghazy Abdel-Nasser A
Published: June 2022

Introduction: Methicillin-resistant Staphylococcus aureus (MRSA) is an emerging cause of morbidity and mortality worldwide. This work aimed to study the occurrence of multidrug-resistant MRSA (MDR-MRSA) in tertiary Egyptian hospitals and determine the antimicrobial susceptibilities and the genetic relatedness of isolates for epidemiological assessment.

Methodology: A total of 170 S. aureus isolates were collected from two Egyptian tertiary hospitals in Cairo, between September 2017 and December 2018. MRSA isolates were identified using the conventional microbiological methods and confirmed by the PCR assays targeting nuc gene, a surrogate marker of S. aureus and the mecA gene for genotypic identification of methicillin resistance. Antimicrobial susceptibility was determined using the Kirby-Bauer disk diffusion method and the isolates were grouped into different antibiotypes based on their antibiograms. The genetic relatedness among MDR-MRSA isolates was determined by ERIC-PCR-based molecular typing. 

Results: High prevalence of MRSA isolates was identified (138/170, 81.2%) with 79% of isolates (109/138, 79%) being MDR-MRSA. MRSA isolates were resistant to diverse classes of antimicrobials including β-lactams, aminoglycosides and macrolides. Among MRSA isolates, the highest resistance rate was to each cefoxitin and penicillin (100%) and the highest susceptibility was to linezolid (92%). Based on the antibiograms of 109 MDR-MRSA isolates, 52 antibiotypes were determined, and 46 different ERIC fingerprints were identified among MDR-MRSA antibiotypes.

Conclusions: MRSA infections remain a noteworthy problem in Egyptian hospitals. MDR-MRSA isolates showed significant genetic diversity indicating the alarmingly high prevalence. Studies should be performed frequently, even in each healthcare setting, to determine the epidemiology of MRSA isolates and their antimicrobial susceptibility profiles for effective control measures of MRSA infections and better healthcare management.
Permutation binary neural networks: Analysis of periodic orbits and its applications
Authors: Udagawa Hotaka , Okano Taiji , Saito Toshimichi
Published: June 2022

This paper presents a permutation binary neural network characterized by local binary connection, global permutation connection, and the signum activation function. The dynamics is described by a difference equation of binary state variables. Depending on the connection, the network generates various periodic orbits of binary vectors. The binary/permutation connection brings benefits to precise analysis and to FPGA based hardware implementation. In order to consider the periodic orbits, we introduce three tools: a composition return map for visualization of the dynamics, two feature quantities for classification of periodic orbits, and an FPGA based hardware prototype for engineering applications. Using the tools, we have analyzed all the 6-dimensional networks. Typical periodic orbits are confirmed experimentally.

Análisis arqueológico y arquitectónico de la fortaleza de Bizilyāna
Authors: Ortega López David
Published: June 2022

El presente artículo pone de manifiesto las carencias de conocimiento arqueológico e histórico acerca de la fortaleza de Bizilyāna. De este modo, nos hemos planteado llevar a cabo un análisis arqueológico y arquitectónico de los muros, torres y otros elementos emergentes que se conservan, cuya lectura sirve para aproximarnos a su origen y diversas etapas constructivas, teniendo siempre en cuenta paralelos indicados por otros investigadores. Los resultados de nuestra investigación delatan la posible existencia de un asentamiento en altura correspondiente a los siglos VI-VIII, así como la fundación de la actual construcción de mampostería entre los siglos X-XI. Sobre ella, se levantaba una obra de tapial de planta poligonal que se adapta al terreno. En los siglos XII-XIII, se le añade una barbacana. Se identifican además una reforma del siglo XIV y una última reconstrucción de finales del siglo XV, esta ya realizada por los cristianos.
La conservación selectiva de la estratificación histórica en Leopoldo Torres Balbás. Crítica y conocimiento en la restauración
Authors: Barrios Rozúa Juan Manuel
Published: June 2022

El objeto de este artículo no es valorar globalmente la metodología del arquitecto Torres Balbás, sobre la cual se han realizado aproximaciones con diversos matices. Lo que aquí se aborda es un aspecto muy concreto, el de cómo conservar la sedimentación histórica en un monumento y qué requisitos es preciso reunir para poder tomar decisiones en materia tan delicada. Su pesimismo hacia la formación de la mayoría de los arquitectos españoles le llevó a defender una elevada prudencia y un fuerte control de instancias superiores. Por el contrario, sí confiaba en sus propias capacidades y hay, en consecuencia, un contraste entre algunos de sus textos, que llaman a una estricta contención conservadora, y una práctica mucho más activa en la que, apoyándose en rigurosos estudios, procede a suprimir de manera selectiva ciertos elementos para lograr una mejor lectura del edificio y realzar sus valores artísticos.
La muralla de Reccopolis (Zorita de los Canes, Guadalajara): técnicas constructivas y transformaciones de un circuito defensivo de periodo visigodo
Authors: Diarte-Blasco Pilar , Castro-Priego Manuel , Olmo-Enciso Lauro
Published: June 2022

La expansión del reino visigodo en la segunda mitad del siglo VI se apoyó en buena medida en el levantamiento o reconstrucción de varios conjuntos urbanos y de sus fortificaciones, de los que en las últimas décadas comenzamos a tener una información amplia (Valencia la Vella, Ribarroja; Tolmo de Minateda, Hellín; Punt del Cid, Almenara; Begastri, Cehegín). Entre todos ellos, destaca el núcleo urbano de Reccopolis dotado de un recinto amurallado de casi 2 km de perímetro, siendo uno de los más extensos hasta ahora conocidos en la península ibérica. El análisis de sus características constructivas a partir de un amplio estudio fotogramétrico, con apoyo de imágenes LIDAR, así como la revisión de las intervenciones arqueológicas ha permitido establecer un marco comparativo con otros recintos peninsulares y con la África bizantina, que señala la existencia de un contexto común de usos defensivos y de exaltación del poder a través del empleo de la arquitectura militar.

Published: June 2022

Depuis les années 1980, avec l’essor des expositions temporaires, sous l’effet du développement de la conservation préventive et de la professionnalisation de la régie, le transport d’œuvres s’est imposé comme une préoccupation majeure des professionnels du patrimoine. Dans la continuité de recherches sur les « petites mains » du patrimoine et leur rôle dans la vie des collections, à la croisée de la sociologie pragmatique et de l’anthropologie des sciences et techniques, ce récit est celui d’un convoiement ordinaire, le retour de trois œuvres du musée national d’Art moderne de la Biennale de Venise en 2017. À partir des souvenirs du convoyeur et de la documentation interne, il met en évidence ce qui se joue à chaque étape du transport. En montrant que les œuvres mobilisent toute une écologie, composée des personnes qui les accompagnent, des outils et des matériaux nécessaires à leur déplacement, des documents qui tracent leurs mouvements, ce récit participe à l’écriture d’une histoire située de la mondialisation de l’art.
Transporter, cacher, détruire : les « objets réfugiés » des orthodoxes de Turquie (1912-1924)
Authors: Seraïdari Katerina
Published: June 2022

En adoptant une approche biographique des objets, cet article vise à retracer l’histoire des « objets réfugiés » que les orthodoxes grécophones et turcophones apportèrent en Grèce dans une période qui commence en 1912 (« premier exil ») et qui se termine avec l’échange de populations après la convention de Lausanne de 1923. Trois cas de figure sont examinés : les objets transportés, cachés ou détruits. Seuls ceux qui furent mis en mouvement mais aussi arrivés à destination peuvent aujourd’hui être caractérisés comme « objets réfugiés ». Le transport dans ces circonstances requalifia l’objet, en lui conférant une valeur testimoniale par rapport à la vie d’antan, aux péripéties de l’exil et aux difficultés vécues après l’installation en Grèce.
Water Utilization Rate
Authors: Norouzi Nima
Published: June 2022

In economic growth models, less attention is paid to natural resources and their importance on economic growth. The decline of the world's water resources, especially in countries with inherently limited water resources, such as Iran, has caused a water supply and demand crisis. This chapter deals with the effect of water utilization rate on economic growth. The hypothesis of this research is based on Barrow and Sala's Martin model developed by Barber. According to this model, the effect of the water utilization rate on economic growth can be nonlinear. The tool for measuring the amount of water in this study is the water utilization rate. Other explanatory variables used in the model include the share of water exports, the share of water activities, and the share of gross capital. This chapter uses a self-regression model with distributive interruption with the shore test approach for 1990-2020 for Iran. The estimation results indicate that the relationship between water utilization rate and economic growth for Iran is inversely U-shaped.

Authors: Norouzi Nima
Published: June 2022

The main focus of the studies, which have been conducted mainly by experts from gas-consuming countries, is to evaluate and measure the impact of this forum on the price of natural gas in the main consumer markets. Unfortunately, the issue of homogeneity or heterogeneity of members and the role that this issue can play in the success of the policies and goals of this organization has received less attention. In this chapter, the authors first show the heterogeneity of members and then, with the help of appropriate indicators, rank member countries in influencing policies and achieving the goals of the assembly in the short, medium, and long term. Based on the presented indicators, it can be concluded that Russia, Qatar, and Algeria are the countries that play the most important role in influencing the policies of the assembly in the short and medium-term, while Russia, Qatar, and Iran, respectively, are three influential members in the long-term policies of the assembly.

La descripción de los datos se detalla en función de un conjunto de variables sociolaborales. El estudio se complementa con un análisis bivariable de la asociación entre el nivel salarial de los periodistas encuestados y dichas variables.

Los resultados indican que el nivel salarial de los periodistas en España está asociado a su género, edad, experiencia profesional, tipo de medio donde trabaja, tamaño de la empresa informativa, ubicación geográfica de la empresa, categoría profesional, tipo de contrato y antigüedad en la empresa. Sin embargo, el nivel salarial es independiente de nivel de estudios, titulación universitaria en Periodismo o Comunicación, y titulación en estudios de tercer ciclo. Los hallazgos del estudio—de interés para académicos y organizaciones profesionales—permitirán monitorizar en el futuro los efectos de las políticas de reducción de gastos de los medios en las retribuciones de los periodistas.
The use of objective measures in selecting patients for septal surgery
Authors: Holmstrom M.
Published: June 2022

To improve results in septal surgery patient selection is the mainstay of a successful outcome. Patient history is the basis as well as clinical examination but both are subjective and must be considered towards a background with a high frequency of septal deviation in the population and a lack of good correlation between function and status. Rhinomanometry and acoustic rhinometry as well as nasal peak inspiratory flow are tests of different nasal parameters as resistance to breathing, nasal dimensions and flow. This article illuminates the use of these more objective tests in selection of patients for septo plasty. Objective tests have in several studies shown to predict postoperative satisfaction while normal values can be a marker for a poor surgical outcome. Pros and cons with objective tests are discussed and the conclusion is: operate when there is a good correlation between the patientA`s status, history and the results of rhinometry!

The current surgical trend is to expand the variety of minimally invasive approaches and, in particular, the possible application of robotic surgery in head and neck surgery. For this purpose, we explored the feasibility of a combined transcervical-transnasal approach to the posterior skull base, using the da Vinci Surgical System in 3 cadaver heads. Superb visualization of the sellar, suprasellar and clival regions was possible in all three specimens. The trocars` placement through a transcervical port made a more cephalad visualization possible, eliminating the need to split the palate. The advantages of robotic surgery applied to the posterior cranial fossa are similar to the ones already clinically experienced in other districts (oropharynx, tongue base), in terms of tremor-free, bimanual, precise dissection. The implementation of instruments for bony work will definitely increase the applicability of such a system in the forthcoming years.

The solar cell is assumed to be under light concentration (C=50 Suns) which leads us to take into consideration the electric field induced by electrons concentration gradient. We also take into consideration temperature influence on electron and hole diffusion parameters, on carrier generation rate, on carrier intrinsic concentration and on silicon energy gap. It emerges from results analysis that increase in temperature leads to decrease of open-circuit voltage and the photovoltaic parameters at the maximum power point (MPP) such as electric power, photo-voltage and photocurrent with however a slight increase of short-circuit photocurrent density. It also appears that temperature has a double effect on electrical parameters. The temperature dynamic effect which is characterized by parameters variations linked to operating point displacement caused by temperature variations. And the temperature proper effect which is characterized by parameters variation with temperature at a given operating point. Thus, the combination of these two effects represents temperature effective effect.

Surface water samples from three locations in the Lower Enyong Creek, S.E. Nigeria were sampled over six months i.e June to October (wet season) and November in dry season for heavy metals such as Cd, Mn, Fe, Cu, Ni, Pb, Zn, Cr) using Atomic absorption spectroscopic method. Some specific physicochemical characteristics, such as temperature, hardness, alkalinity, salinity, TDS, TSS, pH and conductivity which are known to influence the interactions and dynamics of trace metal loads in water bodies were also determined. The result of the analysis indicated significant monthly variation of these parameters for the six months. Monthly summary statistics revealed a few seasonal patterns that echoed the hydrologic regime. During the short dry season in August–September period, all the sampled stream channels had lower levels of Cd, Ni, Zn, Cu Cr, Pb and Fe. Salinity, for instance, correlated strongly (p<0.05) with Cu (0.70); Cr (0.56); Ni (0.72); nitrate (0.61) and Na (0.49). However, the concentrations of most heavy metals were low, while Zn content was higher than the WHO standard for surface water which indicated significant contamination by Zn in the water body.

This study aims to analyze the influence of the agricultural sector on poverty in Aceh Province. In this study, the variables used in influencing the poverty level in Aceh Province are the share of Gross domestic product (GDP) in the agricultural sector, labor in the agricultural sector, agricultural land, Farmer Education and Gross Regional Domestic Product (GRDP) per capita. The regression model used in this study is the method of multiple linear regression analysis (ordinary least squares regression analysis) using panel data and a fixed effect approach (fixed effect model) to determine the effect between variables. The results of this study are based on a simultaneous test (Test F) which shows that overall, the independent variables (share of GDP in the agricultural sector, labor in the agricultural sector, agricultural land, Farmer Education and GRDP per capita together show their effect on the poverty level. The results of the study based on a partial test (t test) showed that the share of the agricultural sector GRDP and the GDP per capita variable had a negative and significant effect on poverty and agricultural sector labor had a positive and significant effect on poverty, while the variables of agricultural land and farmer education negative effect, but not significant. The value of Adjusted R-squared in this study is 0.868629. This shows that the 86.86 percent change in the dependent variable, namely the Poverty of Aceh Province, can be explained by the independent variable, namely Share of Agricultural GRDP, Agricultural Manpower, Agricultural Land, Farmer Education and Per Capita GRDP. While the remaining 13.14% is explained by other factors outside the model.
Study on the Effect of Shrubs on Wind Erosion Control in Desert Regions
Authors: Lessani Naqi , Wang Hanfeng , Hamed Nikmal Ahmad
Published: June 2022

The wind velocity reduces by encountering vegetation; thus, a shelter zone is generated at downstream of vegetation. Hence, planting vegetation, mainly shrubs, has widely been used to control sand transportation. However, plant shrubs in a large area of the desert are practically unsustainable and uneconomical. In this study, Computational Fluid Dynamic (CFD) and wind tunnel experiments were carried out to optimize the planting method of shrubs that could decrease the number of shrubs and increase wind erosion controlling efficiency in desert regions. The effects of shrub height, porosity, the number of shrub rows, and space between shrub rows on wind erosion control were studied. Based on the present study results, the downstream of shrubs was divided into three different zones: first erosion zone, sedimentation zone, and second erosion zone. Moreover, with the increase of shrub porosity, the first erosion zone’s length increased. In contrast, the sedimentation zone’s length decreased, whereas the length of the first erosion and sedimentation zones increased with shrub height. Hence, to make a better shelter zone, it is recommended to plant denser shrubs rows at the upstream and sparsely shrub rows at the far downstream.

The paper analyzes the origin and development of the Sociological Club of the Serbian Sociological Society, with a special focus on the work of the Club in the Niš branch. The Sociological Club is recognized as a relevant instrument for achieving the goals of the Society, aimed at promoting sociological knowledge and profession. While the work of the Society has been the subject of previous analyzes, the problem of insufficient connection and involvement of branches has only been sporadically examined. The paper points out the impact of this problem on the development of the Club in the branches. We conducted qualitative analysis of the content of available documentation on the work of the Society, in the editions of the Sociological Review and on the Society’s website. The problem of insufficient visibility of the history of the Club and formalization of the current organization and activities of the Club has been recognized. Significant progress in connecting branches in the last two decades, which was pointed out through the analysis, leaves room for further improvement of the Society’s work through the cooperation of branches, in which we recognize the important role that the Club can play. In order to optimally use the potential of the Club, the possibilities of developing the activities of the Club in the branches, and connecting the branches through the network of coordinators of the Club, were pointed out.
