Published: September 2022

Endometrial polyps are the most commonly observed pathological finding in the uterus. However, to date, there is little data regarding the factors for the development of endometrial polyps in reproductive-age women. This fact determined the direction of our study. A search was conducted among scientific papers in the Science Direct, CochraneLibrary, PubMed databases by keywords (polyps, endometrium, risk factors, reproductive age) for 1994–2022. As a result of the analysis of the scientific literature, we came to the following conclusions: 1. The prevalence of endometrial polyps depends on the studied population, while the actual prevalence is difficult to determine, since the endometrial polyps can be asymptomatic and regress over time. 2. Implementation of endometrial polyps, apparently, depend not on one, but on many factors: genetic, hormonal, metabolic, medicinal. 3. Increasing the amount of endogenous estrogen, the introduction of exogenous estrogen without progesterone component and age are the most important predisposing risk factors for the development of endometrial polyps.

Objective: to determine prognostic significance of low molecular weight metabolites in women with missed abortion. Material and methods: the research included 100 women of reproductive age, 79 of them with missed abortion diagnosed by ultrasound and 21 with progressive pregnancy who were admitted for an artificial abortion. All women underwent immunohistochemical studies of the endometrium and organic acids in blood serum and endometrium were determined by HPLC. Reliably significant organic acids in blood serum and endometrium, associated with metabolic disorders of fatty acids, amino acids, as well as intermediate metabolites in the Krebs cycle. Statistical analysis of the obtained data was performed using the STATISTICA® for Windows, Release 6.0 module package from StatSoft® Inc., USA (2003), serial number AXAR802D898511FA. Results: statistically significant changes were revealed in the profile of organic acids in the studied women at the levels of lactic, pyruvic and 4-hydroxyphenylpyruvic acids. In women with missed abortion, the change in the lactate / pyruvate. In all women with missed abortion, 4-hydroxyphenylacetic were determined, in contrast to women with a progressing pregnancy, combined with morpho-immuno-histochemical features (pronounced focal necrosis, venous fullness, lymphohistiocytic infiltration, increased levels of HLA-DR, CD 16, CD20 expression, reduced VEGF and LIF expression). Conclusion: missed abortion is associated with the accumulation of intermediate metabolites of tyrosine catabolism (4-hydroxyphenyacetic, 4-hydroxyphenylpyruvic and homogentizic acids), which, despite normal levels of TSH and T4, may reflect organ dysfunction. Timely correction of iodine deficiency in the pre-conception period after missed abortion can be a criterion for a successful subsequent pregnancy. Overcoming iodine deficiency potentiates the possibility of a conceptual restoration of fertility after a previous NB.

Scientifically based and experimentally confirmed data on the morphogenesis of the lymphatic system are necessary to clarify critical periods of development characterized by an increased risk of congenital anomalies of the lymphatic system in order to plan and implement effective prevention, diagnosis and correction of related abnormalities. Among the studied anomalies of lymphatic vessels, lymphangioma is most often mentioned — a congenital benign tumor consisting of many cysts of various sizes. Detection of primary fetal lymphangioma in the early stages of intrauterine development is extremely rare. The purpose of the study: to report a case of early diagnosis of congenital cystic lymphangioma and lymphedema of the left lower limb of the fetus. Congenital (primary) peripheral lymphedema, limb lymphangioma is associated with a malformation of the lymphatic system. Taking into account the fact that operative methods of correction of all types of primary lymphedema are considered unreasonable and ineffective, the main attention requires timely detection of this congenital malformation during screening studies of the fetus and the issuance of recommendations for the management of pregnancy, up to termination for medical reasons. It is necessary to raise the issue of genetic counseling of the couple and conducting the necessary genetic studies. The use of modern diagnostic methods allows for the prevention and treatment of abnormalities in the development of the lymphatic system at an earlier stage of the intrauterine period.
A clinical review: schizophrenia, transsexualism or their combination?
Authors: Soldatkin V. A.
Published: September 2022

The change in the position of transsexualism in the new ICD classification, the hot debate about the psychopathological structure of this phenomenon and its relation to other mental disorders determine the relevance of considering the following clinical case.

A detailed clinical description demonstrates the possibility of combining two initially independent disorders - transsexualism and schizophrenia - which gave a bright individual color to the clinical picture and caused difficulties both in the medical and legal aspects of patient care.

At the age of 25, a patient with clinical signs of transsexualism developed acute paraphrenia psychosis. Without medical assistance, according to the mechanisms of sanogenesis, the severity of the condition decreased, but the psychotic state was not recovered. Features of the onset and dynamics of psychosis typical for the continuous type of paranoid schizophrenia (acuteness of development and absence of signs of syndromotaxis) allow us to attribute it to episodic with progressive or stable deficit paranoid schizophrenia variant. It is noteworthy that after the onset of psychosis, the stereotype of the development of birth-assigned gender rejection syndrome did not undergo significant changes: the formation of crossdressing, inverse psychosexual identity and inverse gender identity were finally completed; mimicry reactions became bright, self-destructive tendencies began to appear more and more clearly, and the patient applied for permission to change gender.

In the described clinical situation, the primary task is to overcome the acute schizophrenia psychosis. After solving this problem, the secondary prevention and rehabilitation program development becomes more important. Formally, the patient does not have the right to change sex, since she suffers from schizophrenia, which is a contraindication for sex transformation. In the state of psychosis, the patient essentially loses her civil procedural capacity. Informally, the question remains relevant.

Glucocorticoids (GC) are one of the most common drugs in the practice of doctors of various specialties because of their therapeutic effects. The increased number of usage is related to the current SARS-CoV-2 virus pandemic. However, GC therapy has serious obstacles caused by side effects, including those leading to fatal outcomes. Side effects include: glucose and lipid metabolism impairments, weight gain, sleep disorders, thromboembolism, atherosclerosis, osteoporosis, myopathy, etc. The described processes cause a direct increase in the risk of developing cardiovascular diseases (CVD) even with short-term therapy and low doses of GC, which affects the further life, prognosis and outcomes of the underlying disease. This review describes in detail the pathogenetic mechanisms and the mutual influence of the side effects of GC, their contribution to the subsequent occurrence of CVD and focuses on the danger of irrational use of GC therapy.

Published: September 2022

Background

Mobile health apps are increasingly used as early intervention to support behavior change for diabetes prevention and control, with the overarching goal of lowering the overall disease burden.

Objective

This prospective cohort study conducted in Singapore aimed to investigate app engagement features and their association with weight loss and improved glycemic control among adults with diabetes and prediabetes from the intervention arm of the Diabetes Lifestyle Intervention using Technology Empowerment randomized controlled trial.

Methods

Diabetes and prediabetes participants (N=171) with a median age of 52 years, BMI of 29.3 kg/m2, and glycated hemoglobin (HbA1c) level of 6.5% and who were being assigned the Nutritionist Buddy Diabetes app were included. Body weight and HbA1c were measured at baseline, 3 months, and 6 months. A total of 476,300 data points on daily app engagement were tracked via the backend dashboard and developer’s report. The app engagement data were analyzed by quartiles and weekly means expressed in days per week. Linear mixed model analysis was used to determine the associations between the app engagements with percentage weight and HbA1c change.

Results

The median overall app engagement rate was maintained above 90% at 6 months. Participants who were actively engaged in ≥5 app features were associated with the greatest overall weight reduction of 10.6% from baseline (mean difference −6, 95% CI −8.9 to −3.2; P<.001) at 6 months. Adhering to the carbohydrate limit of >5.9 days per week and choosing healthier food options for >4.3 days per week had the most impact, eliciting weight loss of 9.1% (mean difference −5.2, 95% CI −8.2 to −2.2; P=.001) and 8.8% (mean difference −4.2, 95% CI −7.1 to −1.3; P=.005), respectively. Among the participants with diabetes, those who had a complete meal log for >5.1 days per week or kept within their carbohydrate limit for >5.9 days per week each achieved greater HbA1c reductions of 1.2% (SD 1.3%; SD 1.5%), as compared with 0.2% (SD 1%; SD 0.6%). in the reference groups who used the features <1.1 or ≤2.5 days per week, respectively.

Conclusions

Higher app engagement led to greater weight loss and HbA1c reduction among adults with overweight or obesity with type 2 diabetes or prediabetes.

Effectiveness of an App-Based Short Intervention to Improve Sleep: Randomized Controlled Trial
Authors: Vollert Bianka , Müller Luise , Jacobi Corinna , Trockel Mickey , Beintner Ina
Published: September 2022

Background

A growing body of evidence for digital interventions to improve sleep shows promising effects. The interventions investigated so far have been primarily web-based; however, app-based interventions may reach a wider audience and be more suitable for daily use.

Objective

This study aims to evaluate the intervention effects, adherence, and acceptance of an unguided app-based intervention for individuals who wish to improve their sleep.

Methods

In a randomized controlled trial, we evaluated the effects of an app-based short intervention (Refresh) to improve sleep compared with a waitlist condition. Refresh is an 8-week unguided intervention covering the principles of cognitive behavioral therapy for insomnia (CBT-I) and including a sleep diary. The primary outcome was sleep quality (insomnia symptoms) as self-assessed by the Regensburg Insomnia Scale (RIS). The secondary outcomes were depression (9-item Patient Health Questionnaire [PHQ-9] score) and perceived insomnia-related impairment.

Results

We included 371 participants, of which 245 reported poor sleep at baseline. About 1 in 3 participants who were allocated to the intervention group never accessed the intervention. Active participants completed on average 4 out of 8 chapters. Retention rates were 67.4% (n=250) at postassessment and 57.7% (n=214) at the 6-month follow-up. At postintervention, insomnia symptoms in the intervention group had improved more than those in the waitlist group, with a small effect (d=0.26) in the whole sample and a medium effect (d=0.45) in the subgroup with poor sleep. Effects in the intervention group were maintained at follow-up. Perceived insomnia-related impairment also improved from pre- to postassessment. No significant intervention effect on depression was detected. Working alliance and acceptance were moderate to good.

Conclusions

An app-based, unguided intervention is a feasible and effective option to scale-up CBT-I-based treatment, but intervention uptake and adherence need to be carefully addressed.

Authors: Purnomo Yudi , Andri Tilaqza
Published: September 2022

Pulutan (Urena lobata) is a medicinal plant used to treat fever, infection and swelling traditionally, although the pre-clinical study about the herbs as analgesic and anti-inflammatory are still limited. The objective of this study is to measure analgesic and anti-inflammatory activity of U. lobata leaf extract through in vivo study and in silico. This study was performed using male wistar rats divided into eight groups (two control groups and six test groups) (n=5). U. lobata leaf was extracted by water and ethanol, each prepared in dose of 125, 250, 500 mg/kg body weight. Anti-inflammatory activity was evaluated by plethysmometer for 6 hours, meanwhile analgesic activity was examined by analgesymeter for 4 hours. The data was analyzed using one way ANOVA test continued with LSD test (p < 0.05). Following active compound identification using Liquid Chromatography-Mass Spectra (LC-MS/MS), several compounds were used in an in silico study using docking server. Both aqueous and ethanolic extract of U.lobata at 125 and 250 mg/kg bw inhibited paw edema with an Area Under Curve (AUC) volume about 10 % and 5%, respectively, compared to control group (p<0.05). For analgesic activity, aqueous extract of U. lobata were able to increase the AUC for pain threshold of about 30-100 % compared to control group (p<0.05), whereas the activity of ethanolic extract lower than aqueous extract. Stigmasterol and beta-sitosterol in U. lobata potentially inhibited Cycloxygenase-2 (COX-2) as a pro-inflammatory mediator and pain. Aqueous and ethanolic extract of U. lobata have analgesic activity and anti-inflammation, the mechanism was predicted through inhibitory activity of COX-2.

Published: September 2022

The World Health Organization (WHO) declared COVID-19 a global pandemic on March 11, 2020. Pharmacists as health workers also have an important role in this pandemic. This study wants to look deeper into how pharmacists perceive their role and pharmaceutical services during this pandemic. A qualitative study with Focus Group Discussions (FGDs) was utilized. Fifteen pharmacists from Kepulauan Riau province were involved. They were purposively selected to include pharmacists from the community pharmacies, hospitals, and community health centers. The FGDs were conducted with Zoom meetings and were recorded. The data were then transcribed and analyzed with inductive content analysis.  This study found five themes with 18 sub-themes. The five themes are the roles and efforts of pharmacists in managing medicines, medical devices, and disposable medical materials (personal protective equipment); the roles of pharmacists in providing pharmaceutical care; community behaviors during the pandemic; development of pharmacists’  roles and capacity during the pandemic; and external factors influencing the roles and practice of pharmacists during the pandemic. During the pandemic, pharmacists continued to work according to their previous roles and adjusted their roles and practice in pharmaceutical services to follow changes in community behaviors.  This condition also encouraged pharmacists to develop their roles and capacities. The healthcare management team, the government, and the professional organizations influenced their roles, both positively and negatively. The results of this study provide a deeper understanding of pharmacist roles and practices during the pandemic. This understanding will be useful for the pharmacist in developing their potential and capability to be involved as healthcare professionals, specifically during the pandemic situation and generally in disaster management.

Authors: Nangimi Ana Fiin , Tafrihani Ahmad Syauqy , Adisusilo Midori Rahmadhany Putri , Jenie Riris Istighfari
Published: September 2022

Jatropha (Jatropha curcas) is often used as biodiesel because of the oil content in its seeds. The production of jatropha oil generates a byproduct in the form of jatropha seed meal, which contains compounds with cytotoxic activity and phorbol esters, as co-carcinogens and tumor promoters. Meanwhile, metastasis is one of the characteristics of cancer where the cells spread to another tissue. This study aimed to determine the potential of jatropha seed meal as a chemoprevention agent, particularly an antimetastatic one, under bioinformatic study and molecular docking. Genecards and DAVID were performed to explore the protein involved in the metastatic process and its gene ontology. The prediction target protein was caught by SwissTargetPrediction. Jatropha seed meal showed the presence of isoamericanol A, myricetin, daidzein, gallic acid, and rutin. There are 11 prediction target proteins correlated to metastatic in extracellular matrix components. Then we were docked to a protein involved in metastasis, matrix metalloproteinase (MMP)-9 (PDB ID: 6ESM) using MOE software. The docking score determined the interaction properties. The docking analysis revealed that isoamericanol A, daidzein, and myricetin exhibited better binding affinity than native ligands and other compounds. Moreover, based on our literature study, the jatropha seed meal contains isoamericanol A, rutin, myricetin, daidzein, and gallic acid, which present anticancer properties by inhibition of cell invasion and migration, cell cycle arrest induction, and suppression of the MMP-9 activity. Overall, jatropha seed meal has potential as an antimetastatic agent. A comprehensive study is needed to explore the possibility of developing it as a supportive agent in combination with a chemotherapeutic agent.
ONE-BIT QUANTIZER PARAMETRIZATION FOR ARBITRARY LAPLACIAN SOURCES
Authors: Aleksić Danijela , Perić Zoran
Published: September 2022

In this paper we suggest an exact formula for the total distortion of one-bit quantizer and for the arbitrary Laplacian probability density function (pdf). Suggested formula additionally extends normalized case of zero mean and unit variance, which is the most applied quantization case not only in traditional quantization rather in contemporary solutions that involve quantization. Additionally symmetrical quantizer’s representation levels are calculated from minimal distortion criteria. Note that one-bit quantization is the most sensitive quantization from the standpoint of accuracy degradation and quantization error, thus increasing importance of the suggested parameterization of one-bit quantizer.
HETEROGENEOUS DEPENDENCE OF OIL-FOOD PRICE DYNAMICS IN AFRICA'S NET OIL-EXPORTING COUNTRIES
Authors: Ogede Jimoh Sina , Ajayi Felix O.
Published: September 2022

The determinants of food prices have attracted sizeable debates among scholars over the last three decades. However, many of these studies ignore the possibility that the impact of oil prices on food prices could vary across the food price distribution. The paper employs a quantile regression technique to ascertain whether food prices respond to the potential heterogeneous impact of crude oil price changes in the six selected African net oil-exporting countries. The coefficient of negative oil price shocks in the panel OLS model is insignificant and positive at the 5% significance level. In contrast, the coefficient of positive oil price shocks significantly affects food prices for the chosen African countries. The quantile regression analysis's empirical findings highlight the diverse dependence effects of various ranges on food prices. All coefficients are non-significant across all quantiles for negative oil price shocks, a conclusion consistent with panel least squares estimate results. Besides, the findings prove that positive changes in oil prices significantly affect the magnitude of food prices in selected African countries. The article concludes that the influence of crude oil price variations on food prices is diverse and positive across quantiles for a subset of Africa's net oil-exporting countries. The findings of this study could have a crucial policy and economic implications for economic agents and stakeholders in diverse fiscal environments. As a result, economic agents must make timely decisions to respond to the effects of oil price uncertainty on Africa's food market.
THE CHALLENGES IN AUDITING FINANCIAL STATEMENTS AT FAIR VALUE CONCEPT (FVC) IN DEVELOPING ECONOMIES: THE CASE OF REPUBLIC OF SERBIA
Authors: Bonić Ljiljana , Janković-Milić Vesna , Rupić Bojan
Published: September 2022

Some balance sheet items are the result of judgments, including fair value estimates, so the relevant evidence is very complicated to collect by auditors, thus the risk of misstatements in financial statements is inevitably greater. The research objective of this paper is to: a) highlight the problems encountered by auditors from developing countries when auditing FV accounting estimates; b) identify the challenges that auditors from Serbia face in auditing FV accounting estimates; c) consider the possibility of adequately responding to these audit challenges in Serbia. The research confirmed that the problems of auditors in Serbia in the audit of FV estimates are generated by inefficient capital markets, and that they are primarily in the field of FV assessment which are connected  to the impossibility of applying the market model and higher volatility of  FV financial statements, as well as those in the field of auditing techniques used in providing assurance on the objectivity of FV assessments in various business activities, which requires additional training of auditors. Thus, the research confirmed the similarity of the problems in Serbia with the problems in the auditing FV estimates in developing countries.
DYNAMIC ANALYSIS OF THE RIGID-FLEXIBLE EXCAVATOR MECHANISM BASED ON VIRTUAL PROTOTYPE
Authors: Yuan Yongliang , Ren Jianli , Wang Zhenxi , Mu Xiaokai
Published: September 2022

In this paper, the excavator’s dynamic performance is considered together with the study of its trajectory, stress distribution and vibration. Many researchers have focused their study on the kinematics principle while a few others focused their work on dynamic performance, especially the vibration analysis. Previous studies of dynamic performance analysis have ignored the vibration effects. To address these challenges, the rigid-flexible coupling model of the excavator attachment is established and carried out based on virtual prototyping in this study. The dipper handle, the boom and the hoist rope are modeled as a flexible multi-body system for structural strength. The other components are modeled as a rigid multi-body system to catch the dynamic characteristics. The results show that the number of flexible bodies has little effect on the excavation trajectory. The maximum stress determined for the dipper handle and the boom are 96.45 MPa and 212.24 MPa, respectively. The dynamic performance of the excavator is greatly influenced by the clearance and is characterized by two phases: as the clearance decreases, the dynamic response decreases at first and then increases.
THE EFFECT OF ELECTRON-BEAM TREATMENT ON THE DEFORMATION BEHAVIOR OF THE EBAM TI-6AL-4V UNDER SCRATCHING
Authors: Shugurov Artur R. , Nikonov Anton Y. , Dmitriev Andrey I.
Published: September 2022

The effect of the continuous electron beam scanning (CEBS) post-treatment on the microstructure, mechanical properties and scratching behavior of the Ti-6Al-4V alloy samples produced by electron beam additive manufacturing was studied experimentally and by using molecular dynamics simulation. It was found that the CEBS post-treatment resulted in the transformation of the microstructure of the samples from the α′-martensite into the α+β structure. The evolution of the sample microstructure was shown to provide improved mechanical characteristics as well as enhanced deformation recovery after scratching. A mechanism was proposed based on the results of molecular dynamics simulation, which attributed to the improved recovery of the scratch groves after passing the indenter to reversible β→α→β phase transformations, which occurred in the vanadium alloyed Ti crystallites.
THE CARBON NANOTUBE-EMBEDDED BOUNDARY LAYER THEORY FOR ENERGY HARVESTING
Authors: He Ji-Huan , Y. Abd Elazem Nader
Published: September 2022

Single-walled carbon nanotubes (SWNTs) and multi-walled nanotubes (MWNTs) are gaining appeal in mechanical engineering and industrial applications due to their direct influence on enhancing the thermal conductivity of base fluids. With such intriguing properties of carbon nanotubes in mind, our goal in this work is to investigate radiation effects on the flow of carbon nanotube suspended nanofluids in the presence of a magnetic field past a stretched sheet impacted by slip state. CNTs flow and heat transmission are frequently modelled in practice using nonlinear differential equation systems. This system has been precisely solved, and an accurate analytical expression for the fluid velocity in terms of an exponential function has been derived, while the temperature distribution is stated in terms of a confluent hypergeometric function. The impact of the radiation parameter, slip parameter, sloid volume fraction, magnetic parameter, Eckart and Prandtl numbers on the velocity, temperature, and heat transfer rate profiles are demonstrated using a parametric analysis. When compared to the two types of nanoparticles (Cooper and Silver) in earlier published articles, temperature profiles for single-walled nanotubes (SWNTs) and multi-walled nanotubes (MWNTs) are revealed to be particularly sensitive to radiation, solid volume fraction, and slip parameters. Nanomechanical gears, nanosensors, nanocomposite materials, resonators, and thermal materials are only a few of the present problem's technical applications.
RISK PRIORITY EVALUATION OF POWER TRANSFORMER PARTS BASED ON HYBRID FMEA FRAMEWORK UNDER HESITANT FUZZY ENVIRONMENT
Authors: Zhou Bin , Chen Jing , Wu Qun , Pamučar Dragan , Wang Weizhong , Zhou Ligang
Published: September 2022

The power transformer is one of the most critical facilities in the power system, and its running status directly impacts the power system's security. It is essential to research the risk priority evaluation of the power transformer parts. Failure mode and effects analysis (FMEA) is a methodology for analyzing the potential failure modes (FMs) within a system in various industrial devices. This study puts forward a hybrid FMEA framework integrating novel hesitant fuzzy aggregation tools and CRITIC (Criteria Importance Through Inter-criteria Correlation) method. In this framework, the hesitant fuzzy sets (HFSs) are used to depict the uncertainty in risk evaluation. Then, an improved HFWA (hesitant fuzzy weighted averaging) operator is adopted to fuse risk evaluation for FMEA experts. This aggregation manner can consider different lengths of HFSs and the support degrees among the FMEA experts. Next, the novel HFWGA (hesitant fuzzy weighted geometric averaging) operator with CRITIC weights is developed to determine the risk priority of each FM. This method can satisfy the multiplicative characteristic of the RPN (risk priority number) method of the conventional FMEA model and reflect the correlations between risk indicators. Finally, a real example of the risk priority evaluation of power transformer parts is given to show the applicability and feasibility of the proposed hybrid FMEA framework. Comparison and sensitivity studies are also offered to verify the effectiveness of the improved risk assessment approach.

Published: September 2022

Infectious diseases spread by microorganisms, viruses and bacteria, which can be transmitted from individual to individual very quickly and adversely affect public health, need to be treated immediately. In order to eliminate the structures that are harmful to the body or to strengthen the immune system, which is the whole of cells, structures and processes, individuals are vaccinated and the disease is suppressed. Thus, communicable diseases are prevented from threatening public health significantly. This paper offers a nonlinear fractional order system for modeling the effects of vaccination on a SVIR infectious disease. To see the memory effect on the system parameters, the model defined by the ordinary differential equation is redefined with the Caputo fractional derivative. Afterwards, the stability analysis and explanations are given about the fractional infectious disease SVIR model, the existence and uniqueness of the system are made. When $R^{c}<1$, it is seen that the disease is under control by vaccination, through the figures obtained with the help of MATLAB for the fractional SVIR model.

Authors: Mimović Predrag , Budimčević Kristina , Marcikić - Horvat Aleksandra
Published: September 2022

Over the past decades, the rapid development of the airline industry has occurred in the Middle East and particularly in the United Arab Emirates. The need for the development of the aviation sector has emerged due to the strategically important position that Middle East occupies as the central point between the eastern and western hemispheres. Its major airlines, so called Middle East Big Three (MEB3) - Emirates, Etihad and Qatar Airways, have become dominant in the region, as well as across the globe, primarily thanks to the high quality of their services and globally recognized brand. The focus of the assessment are the airlines’ non-financial performance indicators, such as: the number of carried passengers and cargo, number of employees, serving destinations, fleet size, etc. The analysis covered a period of twelve years, starting from 2005 until 2016, which was characterized by the expansion of these airlines. For each observed company, the efficiency was first separately measured using the Data Envelopment Analysis (DEA) method, followed by the dynamic analysis and measurement of their efficiencies using the DEA Window analysis. In both cases, Emirates Airlines had the best performance.

Authors: Amidžić Renata , Leković Bojan , Ivanović-Đukić Maja
Published: September 2022

We investigated the factors influencing the intention of entrepreneurs driven by opportunity (ODE) and entrepreneurs driven by necessity (NDE) in the countries of South-East Europe (SEE). The aim of the paper was to identify the key factors of entrepreneurial intentions of ODE/NDE and to propose measures the application of which can transform NDE into ODE and increase the contribution of total entrepreneurial activity to economic development. The Binomial Logistics Regression and Ordinary Logistics Regression were applied, using data for 125,444 entrepreneurs in seven countries of SEE. Our findings highlight that the intention of ODE is most influenced by entrepreneurial knowledge and experience, entrepreneurial alertness and social contacts and networks, while unemployment (as a work status) and low household income have a significant impact on the intention of NDE. The fear of failure has a negative influence on the intentions of both groups of entrepreneurs, but its impact is much more accentuated in NDE than in ODE.
ECONOMIC GROWTH AND TAX COMPONENTS: AN ANALYSIS OF CORPORATE INCOME TAX INCENTIVES AND THEIR IMPACT ON THE ECONOMIC GROWTH IN SERBIA
Authors: Đurović Todorović Jadranka , Ristić Cakić Milica , Starčević Vitomir
Published: September 2022

The paper empirically examines the effects of incentives in the domain of corporate income tax in Serbia between 2007 and 2018. The main aim of the paper is to test for effects of tax incentives on economic growth. To achieve the stated aim, a dataset consisting of 10 indicators will be analyzed by using the Principal Component Analysis method. This method allows the initial set of predictors to be transformed into a set of uncorrelated components, and allows linear regression to be performed. In accordance with the results of the analysis, the proposal for parametric reform should be based on the abolition of certain tax incentives in order to increase the efficiency of corporate income tax and improve business conditions. The analyzed data has shown that certain corporate tax incentives have had a significant effect on economic growth. Taking into consideration the adverse effects of the coronavirus crisis, the authors give recommendations on what should be developed in the domain of corporate income tax.

Published: September 2022

Este trabalho analisa a construção identitária nas festas religiosas de Dianópolis que ocorrem na Missão, zona rural da cidade. Pretende-se relacionar a festa com a identidade local a fim de contribuir para valorizar os elementos da cena festiva. As festas religiosas de Dianópolis são estruturantes para a identidade do local. Dentre as festas que ocorrem na cidade, as que ocorrem na zona rural (missões e sucupira) fazem parte da tradição festiva, principalmente para os moradores mais velhos que professam a fé católica. É possível perceber mudanças no modo de fazer, inclusive nas músicas que fazem parte do ritual, nas folias e nas composições das rodas e benditos pelos foliões. O espaço, que hoje é visto como um lugar de festa, no passado foi um lugar de sofrimento, de lutas e resistências, de dominação racial e de perseguição étnica. Índios e negros que viviam na região passaram por condições sub-humanas, de escravidão, aprisionamento pelas mãos de colonizadores.

The COVID-19 pandemic has affected the lives of people worldwide. Governments struggled to persuade citizens to obey ongoing lockdowns and social restrictions to fight the transmission of the virus. The purpose of this paper is to investigate the impact of prosocial behavior during COVID-19 and big-five personality traits on compliance with health-protective behavior against COVID-19. To examine possible predictors an online questionnaire was delivered to undergraduate students at a public university of Athens during the second phase of the pandemic (November 2020). A mediation analysis was performed to test the relationships among variables. The sample consisted of 239 business school students and the results revealed that two of the big-five personality traits of young adults, conscientiousness, and neuroticism, can be linked with a positive attitude to following heath precautions and recommendations while conscientiousness and agreeableness are predictors of young adults’ prosociality behavior to cope with the COVID-19 pandemic. Finally, the results indicated that there is not any effect of young adults’ personality traits on health recommendation through the mediation of prosociality. The results will contribute to the recent literature (Campos-Mercade, Meier, Schneider, & Wengström, 2021; Miles, Andiappan, Upenieks, & Orfanidis, 2021) on the factors influencing prosocial decision-making regarding the pandemic.

The objective of this work was to evaluate the physicochemical characteristics, the bioactive compounds and the antioxidant potential of honey produced by Africanized bees (Apis mellifera L.) from municipalities in western Paraná state. Sixty-six samples of honey were analyzed from October 2018 to August 2019. The physicochemical parameters evaluated were: color, moisture, hydroxymethylfurfural, pH and free acidity, with mean values ​​of 0.36±0.24nm, 18 .80±1.01%, 10.34±3.24mg.kg-1, 4.01±0.18 and 17.36±4.11 meq.kg-1, respectively. The bioactive compounds (phenolic compounds and flavonoids) and the antioxidant activity were also analyzed, and the mean values ​​of 16.34±7.41mg.GAE 100 g-1 were observed for Total Phenols, 21.35±9.63mg.QE 100 g-1 for flavonoids and 0.09±0.03µmol.TE g-1 for antioxidant activity (DPPH). The honey samples were influenced by their phytogeographic origin and have antioxidant potential.

The aim of this study was to determine concentrations of nitrogen (N) in two biomes, Atlantic Forest (AF) and Cerrado (CR), at the interface between terrestrial and aquatic ecosystems. This involved evaluating N in vegetation (litterfall), soil and water in small watersheds in environmental protection areas in northeastern Brazil. Soil chemical and physical analyzes were performed and mineralization and nitrification rates were determined. The forms of organic, inorganic and particulate nitrogen in water were determined by spectrophotometry. Two collections were carried out, one in the dry season (October and November 2019) and another in the rainy season (February and March 2020), in two environmental preservation areas, Estação Veracel Private Natural Heritage Reserve - (Atlantic Forest) and Chapada Diamantina National Park (Cerrado), with five small watersheds sampled in each biome. The N concentration in litterfall was similar in both biomes, with averages of 0.69%. In relation to soil and water, N concentrations were higher in AF compared to CR, with concentrations of 0.95 ± 0.40 and 0.59 ± 0.14 µg.Ng-1 of nitrate in the soils of AF and CR, respectively, and 3.53 ± 2.51 µM of nitrate in water in AF and 0.76 ± 0.78 µM in CR.
Aydınlanma Sonrası Eleştirel Felsefe Geleneğinde İki Düşünür: Hegel ve Foucault

Published: September 2022

Hegel ve Foucault üzerine literatürdeki genel kanaat, bu iki düşünürün çoğu zaman zıt kutuplarda yer aldığı yönünde olsa da Foucault’nun kavramsallaştırmalarında Hegel’den izler taşıması, her iki düşünürün de bazı ortak paydalarda buluşması ve diğer karşılaştırmalı analizlere kıyasla ikisi arasındaki paralellikler üzerine literatürdeki çalışmaların az olması, bu araştırmanın özünü oluşturmaktadır. Dolayısıyla, bu araştırma, Hegel ve Foucault karşılaştırması üzerine bir çalışma olarak, akıl, mantık ve mutlak bilgi söz konusu olduğunda, iki düşünür arasında ortaya çıkan belirgin karşıtlıkları göz ardı etmeden, Hegel’in fenomenolojik, Foucault’nun ise soykütüksel bir yöntem ile ele aldığı siyasi özgürlük, tarih ve modernite kavramlarından oluşmakta, Hegel felsefesinin Foucault üzerindeki etkilerini, özgürlük ve modernite hususlarında iki düşünürün benzerlik ve farklılıklarını, Kantçı zeminden nasıl ilham aldıklarını, farklı yöntemlerle de olsa felsefi eleştirilerde buluştukları noktaları konu almaktadır. Araştırma süresince yapılan incelemelerden yola çıkarak, zaman zaman ortak noktada buluşarak benzer eleştiriler getirdiklerini vurgulamanın bu kavramların tarihsel analizini yapmak ve iki düşünürün çalışmalarını daha derin irdeleyebilmek adına önem arz ettiği sonucuna varılmıştır.
De volta à Montanha Mágica

The paper seeks to highlight the precise sense of timeliness of one of the most relevant writers of the troubled 20th century. With his work “The Magic Mountain”, Thomas Mann reveals the ordeals of German society, which, in fact, mirrors the latent tragedies in Europe that triggered the First and, later, the Second World War. The leading role of German science and culture is explained by its economic and technological high standards at the beginning of the 20th century. If development at levels not seen before was able to provide improvements in life, it was not efficient in resolving human disputes marked by bloody conflicts. At the existential level, the ordeals were no less challenging. The description of a character’s change of life, the never-ending conflict of ideas arising from the coexistence of minds with distinct experiences, and the duality of ideas explored unfold in a unique narrative in this novel from the beginning of the century. This is a bibliographical and documentary research carried out in the theoretical field with a qualitative approach. We propose an analysis of the personal conflicts of each character, aligned with the underlying reality and connected to it. We conclude that Mann’s impact and understanding of the human condition goes beyond his time and is still meaningful in the 21st century.
