Authors: You Yan , Hu Yanchuan
Published: January 2023

Rural e-commerce is a powerful tool for rural economic revitalization, and it will continue to transform and survive with the continuous promotion of rural revitalization. Analyze the mechanism and path of farmers’ connection to the e-commerce market, study its development rules, summarize the existing practical experience, and analyze emerging new models. Through the establishment of supply and marketing cooperatives, more employment opportunities would be provided, enhance the regional economic strength, and meet the diversified consumption needs of farmers. Establish a co-construction mechanism between farmers, e-commerce markets, and the government, explore the “rural e-commerce+rural tourism” model, encourage farmers to start businesses and generate income, provide theoretical support and practical experience exploration for achieving sustainable development and rural revitalization, and make positive contributions to the implementation of the rural revitalization strategy.
Portrayal of Indian History and Politics in Shashi Tharoor’s The Great Indian Novel
Authors: Surekha Dr.
Published: January 2023

Shashi Tharoor’s award winning work The Great Indian Novel showcases an allegorical representation of recent history and politics modelled on the ancient epic Mahabharata. . He has taken the epic as a blueprint and filled it with a contemporary cast for his witty sent-up of pre and post-independence India. The history of India’s struggle against colonial rule and her postcolonial tryst with democracy is presented in an epic vein. Tharoor’s strategy, bases on both the modern problematization of history and politics; and Indian traditions is both culturally appropriate and subversive in terms of internal affairs as well as imperial history and its modern legacies

Authors: N Anish Jackson , Shyamsundar Susmitha
Published: January 2023

The digital transformation that happened in the field of education has made its way in teaching methodology supported by the integration of digital technologies. With the normalization of using digital technology among the generation Z and Alpha, the educational approaches are being constructed and reconstructed using latest digital technologies. The change in approaches can be identified from computer assisted to mobile assisted, blended to flipped and regular courses to Massive Open Online Courses (MOOC) or Learning Management System (LMS). In the context of language teaching and learning, the current digital technologies are being supportive tools in imparting language skills. Hence, this study aims to analyse the effectiveness of integrating Microsoft Teams (Teams) as an LMS tool to support language teaching using Substitution, Augmentation, Modification and Redefinition (SAMR) framework. The four degrees of the SAMR framework helps in understanding the effectiveness of the integration of digital technologies to language teaching methods. The findings of the study conclude that MS Teams can be considered as an efficient LMS tool for language teaching-learning process.
О статуэтке из Национального музея Рес­публики Татарстан

Introduction. The article deals with an item contained in the Buddhist Collection of Tatarstan’s National Museum. Buddhist art is essentially canonical, which sets forth some difficulties to be faced when it comes to refer certain pieces to different regional schools. Goals. The paper attempts a comparative analysis of the Buddhist statuette from the National Museum of Tatarstan and suggests an attribution of the unique item. Results. The analysis shows the figurine (inv. no. КП-10367/9) depicts a Mongolian Lama. It is headdress that proves a most significant element since the former is characteristic of Jebtsundamba Khutuktus of Khalkha. So, our further insights do attest to the statuette depicts a Bodg Gegeen of Mongolia. And there is reason to presume this is an early sculptural portrait of the 8th Bodg Gegeen — Jebtsundamba Khutuktu of Khalkha.

Introduction. The paper examines collections of rare Mongolian-language Christian editions housed at depositories of Zabaykalsky Krai and Buryatia. Goals. The study attempts a socioarchaeographic analysis of the mentioned collections at the Institute for Mongolian, Buddhist and Tibetan Studies (SB RAS) and the Kuznetsov Zabaykalsky Krai Museum of Local History and Lore. Materials and methods. In terms of methodology, the work rests on ‘cognitive history’ and some aspects of historical phenomenology. The paper assumes a content analysis of the collections be instrumental both in identifying Christian Buryat readers’ queries throughout the 19th and early 20th centuries, and in revealing specificities of missionary activity among Mongolic peoples in pre-revolutionary Russia. Conclusions. The content analysis of the two collections shows Transbaikalia was witnessing a specific cooperation between Protestant and Orthodox Christian missions. Personal libraries of Buryat Christians were largely compiled from Mongolian translations of the Bible funded mainly by the Protestant missions. The study attests to that the most promising missionary activity among Buryats (and Mongols at large) — dissemination of Christianity via primary education — was not supported by representatives of the missions. Our insights into the history of the collections show that results of Christian missionary translation activities aroused interest of Buryat Buddhists, and the latter tended to include such biblical translations into their libraries. Due to linguistic and historical circumstances, the Russian collections of Mongolian-language Christian publications have remained virtually unattended — both in terms of bibliographic description and scholarly research — for a long time. However, territorial, manufacturing and historical circumstances make the examined editions essentially unique. Our content analysis confirms there is a need for such investigations to reveal a coherent agenda of religious publications once used for the development of Christianity within Mongolian culture.
Савар = медведь и Кёкеде Мерген — персонажи космогонического мифа о небесном охотнике (на материале сказочно-эпической традиции калмыков)
Authors:   Kalmyk Scientific Center of the RAS (8, Ilishkin St., 358000 Elista, Russian Federation), Ubushieva Danara V.
Published: January 2023

Introduction. Folklore narratives recorded at the turn of the 20th century contain ideas inherent to the ancient worldview of Kalmyks and dating back to the period of hunting and cosmogonic knowledge. So, insights into folktale / epic heritage abundant in mythoritual experiences of the ethnos can significantly supplement the available ethnographic data. Goals. The article aims at supplementing a reconstruction of the cosmogonic mythical plot of the heavenly hunt and seasonal changes. Materials and methods. The paper employs the structural / semantic, structural / typological, and comparative methods to analyze some Kalmyk folktale and epic texts. Results. The analysis shows an obvious connection between Savar = bear and Kökede Mergen which is consistent with the scheme: myth of a hunter / bear → archaic legend of Savar = hunter / bear → folktale of Kökede Mergen the hunter. The textual implementations attest to that both the characters had evolved from the mythological plot about origins of the constellation Orion. However, the difference is that the story of Savar = hunter / bear has been preserved by Kalmyks in an implicit form and is rather manifested in ethnographic substrates, whereas other Mongolic peoples have independent mythological stories about the heavenly hunter Kökede Mergen. The examined motifs of the hero’s miraculous birth and path, migrations of characters typical for bear-related and funeral rites, as well as the connection with the heavenly mare supplement the previously analyzed motifs of Savar’s travels along the lunar road, brotherhood with the bear, similarity of Savar’s sleep to the bear’s hibernation coupled with prohibitions related to the bear’s ability to hear, and the tradition of performing the epic only in evenings, at night, and in winter time. These cluster together to form a set of motifs derived from the nuclear mythological plot about the heavenly hunt and seasonal changes. The considered connections between Savar = bear and Kökede Mergen confirm the cosmic hunter / bear had been replaced by an anthropomorphic character, and attest to there may have existed an archaic plot with the character Savar = hunter / bear, since the image of Savar the hero in the Kalmyk epic still retains anthropomorphic features of the latter. Perhaps, Savar the hero = bear is a transitional image between the hunter / bear and Kökede Mergen, which coincides with the hypothesis that the bear’s image had been replaced by the anthropomorphic character of celestial hunter Kökede Mergen, and the latter be confirmed by plots and motifs of Kalmyk folktales and epic.

El libro “Recuperaciones diversas ante el proceso de desastre. Reflexiones y perspectivas para México” nace de la necesidad de entender y atender una fase específica de la gestión integral del riesgo de desastres, concebida como política pública: la recuperación. Un problema que se encuentra en el núcleo epistemológico y normativo de la idea de gestión integral de riesgos de desastre. Los autores buscamos documentar y analizar procesos que inciden directamente en la recuperación en diferentes sectores, visibilizando los problemas teóricos y prácticos que deben ser parte de nuevas agendas de investigación para el replanteamiento de las intervenciones del Estado y la sociedad civil. Dicha perspectiva multidisciplinar nos ayuda a analizar un conjunto diverso de problemas que ocurren en los años posteriores a un impacto, y que pueden ser igual o más graves que los daños y pérdidas ocurridos durante la fase crítica. Nos referimos, por ejemplo, a problemas psicosociales no atendidos; violaciones a derechos humanos derivadas de un deficiente diseño e implementación de políticas públicas, o la profundización de condiciones de vulnerabilidad de personas o colectivos especialmente frágiles, como las personas mayores o en condición de movilidad forzada. La recuperación como parte del proceso de desastre ayuda a entender cómo las respuestas de mediano y largo alcance pueden constituir la base para nuevos ciclos o hélices del mismo.
Review on Solvents for Extraction of Metals from Waste Electrical and Electronic Equipment (WEEE)
Authors: Obukohwo Aghogho Blessing
Published: January 2023

Abstract: Waste Electrical and Electronic Equipment (WEEE) are electrical and electronic gadgets known to have reached their end-of-life. They are made of printed circuit boards (PCBs) containing valuable metals like copper, gold, iron, lead nickel, silver, tin and zinc which can leach into the environment when landfilled. Current extraction methods for the recovery and recycling of metals from WEEE uses various solvents which are not selective, releases toxic gases and recover metals in a mixed form which requires further purification steps to recover individual metals. This paper has reviewed the use of inorganic acids, organic acids and designer solvents which do not release toxic gases when used for extraction of metals from WEEE. The results reveal that ionic liquids ae promising solvents for extracting metals.
A Systematic Literature Survey on Recommendation System
Authors: Nadeem Rashid , Sivakumar T.
Published: January 2023

Abstract: For many applications, particularly in the academic environment and industry, the Recommendation System for Technical Paper Reviewers is very important. This study examines the research trends connecting the highly technical components of recommendation systems employed in various service fields to their commercial aspects. It is a technique that enables the user to identify the information that will be useful to him or her from the variety of facts accessible. In terms of the movie recommendation system, recommendations are made either based on user similarities in collaborative filtering or by considering the user's intended engagement with the content into account content-based filtering. A stronger recommendation system is produced by combining content-based and collaborative filtering, which overcomes the issues that collaborative and content-based filtering typically have. The similarity between users is also determined using a variety of similarity measures in order to make recommendations. We have reviewed cutting-edge approaches to collaborative filtering, content-based filtering, deep learning-based methods, and hybrid approaches in this study for movie recommendation. Additionally, we looked at other similarity measures. Numerous businesses, including Facebook, which suggests friends, LinkedIn, which suggests jobs, Pandora, which suggests music, Netflix, which suggests movies, and Amazon, which suggests purchases, among others, employ recommendation systems to boost their profits and help their clients. This essay primarily focuses on providing a succinct overview of the many approaches and techniques used for movie recommendation in order to investigate the field of recommendation systems research.
“Paper metropolises” in Amazonia: Lefebvrian perspectives on the production of space in Macapá-Santana, Brazil
Authors: Santos Romário Valente , Villas Boas de Amorim Lima Gabriel , Ferreira Lima José Júlio
Published: January 2023

“Paper metropolises” are urban centers in established metropolitan regions that present no functionalities of a metropolis, in terms of political, economic, and social influence, as well as the flow of information, capital, and people. Thus, this study has sought to understand the conception, perception, and experience of a “paper metropolis” located in the Brazilian Amazon based on Henri Lefebvre’s understanding of the production of urban space. Using a historiographical approach, and a literature and documentary review, it was possible to understand that the conceived space is essentially the result of joint actions among political and economic actors that prioritize the institutionalization of space rather than its production, thereby reflecting the lack of perception and experience of the population in relation to metropolitan space. Thus, particular intra-urban dynamics transform the metropolitan spaces into a product that does not necessarily fit into Lefebvrian theory, creating new horizons for apprehending the socio-spatial production of what constitutes paper metropolises.
“Metrópoles de papel” na Amazônia: Horizontes lefebvrianos na produção do espaço em Macapá-Santana, Brasil
Authors: Santos Romário Valente , Villas Boas de Amorim Lima Gabriel , Lima José Júlio Ferreira
Published: January 2023

“Metrópoles de papel” são centros urbanos de regiões metropolitanas institucionalizadas que não apresentam funcionalidades de uma metrópole, tais como influências político-econômicas e sociais, além do tráfego de informações, capital e pessoas. Assim, este estudo buscou compreender a concepção, a percepção e a vivência de uma "metrópole de papel" localizada na Amazônia brasileira com base no entendimento da produção do espaço urbano de Henri Lefebvre. Utilizando uma abordagem historiográfica, análises de recursos bibliográficos e documentais possibilitaram apreender que o espaço concebido é fruto essencialmente de ações conjuntas entre agentes políticos e econômicos que priorizaram a institucionalização do espaço em vez de sua produção, repercutindo na ausência de percepção e vivência por parte da população com relação ao espaço metropolitano. Por conseguinte, dinâmicas intraurbanas peculiares tornam a produção dos espaços metropolitanos um produto que não necessariamente se encaixa na teoria lefebvriana, criando novos horizontes para a apreensão da produção socioespacial do que se constituem as metrópoles de papel.
Circulação de ideias e suas apropriações: uma reflexão sobre a história do urbanismo na América Latina em diálogo com perspectivas das histórias conectadas e teorias decoloniais
Authors: Roldan Dinalva Derenzo
Published: January 2023

Este artigo discute teorias e abordagens metodológicas em diálogo com outros campos disciplinares para refletir sobre a história do pensamento urbanístico na América Latina, tendo em vista o trânsito de ideias e as apropriações locais de conceitos urbanísticos. Tratar do urbanismo na América Latina impõe uma reflexão metodológica sobre como abordar uma vasta região, uma diversidade de situações, de culturas urbanas e de práticas urbanísticas, mas em que, simultaneamente, é possível identificar problemáticas comuns em um mesmo recorte temporal. Neste sentido, o trabalho ora apresentado se organiza em três eixos: o primeiro põe em discussão as formas de recorte e os modos de análise propostos pela história transnacional ou conectada; o segundo evidencia uma problemática configurada pelos estudos pós-coloniais e teorizada como decolonial a partir da particularidade da América Latina que pode lançar luz à variação dos modelos urbanísticos que perpassam as experiências urbanísticas nela realizadas; e, por fim, o terceiro eixo examina a proposta do estudo das práticas culturais, e suas categorias de análise, para pensar os mecanismos de apropriação.

Authors: Rafiepour Abolfazl , Moradalizadeh Afsaneh
Published: January 2023

In this study, the mathematics of carpet will be introduced by presenting the lifestyle of two expert carpet-weavers from Kerman, Iran, who work for many years in carpet-weaving activities through an explanation of carpet weavers’ culture. This explanation reveals that carpet weavers can do mathematics and solve related real-world problems without academic education in mathematics according to their needs through practical activities. The main purpose of this study is to investigate the mathematical ideas in the art of carpet weavers, and the ethnography approach is used as a methodological framework. Our findings showed that there are many mathematical concepts in the carpet weaving process, such as mirror axes, parallel and diagonal lines, geometric shapes, ratio, and measurement which can be used as context for developing enrich and meaningful mathematical tasks.

Published: January 2023

The pandemic has indeed provided students and teachers worldwide with the experience of technology-infused teaching. Even though the pandemic is almost over, the utilization of technology in mathematics education is still needed and inseparable. Relying on cross-sectional design and phenomenological approach, this research investigates senior high school students' perceptions towards AI-based learning, particularly about their understanding and suggestions towards AI-based learning in mathematics in the context of post-pandemic. The participants of the study were 107 students coming from several islands in Indonesia, ranging from grade 10-12, with an age interval of 15-18 years old. The instruments used were the questionaries with open-ended questions in Microsoft forms distributed to mathematics teachers in several WhatsApp groups. The data were then analyzed through a multistage descriptive and pattern coding process. The findings showed that students need to be facilitated with AI, which can display understandable visualization and provide guidance to solve mathematical problems. It is expected that the present study's findings offer researchers in Indonesia and abroad to disseminate and/or implement AI learning in the form of Intelligent Tutoring Systems.
Economic and environmental benefits of performance management controls in human service transportation planning
Authors: Willox Sara , Morin Jennifer
Published: January 2023

Sustainability strategies are being implemented in organizations as best practices demonstrate that these initiatives not only provide environmental and social benefits but also financial benefits (Nawaz & Koç, 2019). The problem addressed is that community-based human service organizations often rely upon their own vehicles or the personal vehicles of their employees to transport clients, but the skills and resources to apply and implement sustainable transportation best practices are lacking (Busko & Saltzman, 2021). The purpose is to demonstrate how the application of process mapping and systems approach can reduce fuel usage and greenhouse gas emissions, and save time and financial costs which can, in turn, be used to improve the quality of life of those served by these organizations. The methodology is a qualitative grounded theory approach applied by conducting a textual analysis of conceptual approaches that could be applied to transportation in this industry. The results demonstrate that if human service organizations adopt process mapping and systems approach for their transportation, economic and environmental benefits can be achieved. The conclusion reviews the findings and recommendations. This research is relevant because small businesses and nonprofit organizations need to be lean to stay competitive and to provide the best services to their clients.
Factors of fraud triangle affecting the likelihood of material misstatements in financial statements: An empirical study
Authors: Doan Thanh Nga , Ta Thu Trang
Published: January 2023

This study aims to identify and examine the three components of the fraud triangle theory that affect the likelihood of material misstatements in financial statements. With a sample of 150 listed companies from two stock exchanges in Vietnam, Ho Chi Minh City (HOSE) and Hanoi Stock Exchange (HNX) in 2019, this study uses multinomial logistic regression analysis to examine the relationship among factors. This study shows the impact of using the elements of the fraud triangle theory in forecasting the likelihood of material misstatement (Cressey, 1953; Romney et al., 1980). The results indicate that the following factors affect the possibility of material misstatements in financial statements of companies: debt ratio, return on assets, independence of the board members, selection of an audit firm, auditor change in comparison with the previous year, and historical financial statements with material misstatements. These findings of the study can be utilized to develop strategies to help identify companies that are likely to have material misstatements in their financial statements.
Rate limiting step of the allosteric activation of the bacterial adhesin FimH investigated by molecular dynamics simulations
Authors: Interlandi Gianluca
Published: January 2023

The bacterial adhesin FimH is a model for the study of protein allostery
because its structure has been resolved in multiple configurations,
including the active and the inactive state. FimH consists of a pilin
domain (PD) that anchors it to the rest of the fimbria and an
allosterically regulated lectin domain (LD) that binds mannose on the
surface of infected cells. Under normal conditions, the two domains are
docked to each other and LD binds mannose weakly. However, in the
presence of tensile force generated by shear the domains separate and
conformational changes propagate across LD resulting in a stronger bond
to mannose. Recently, the crystallographic structure of a variant of
FimH has been resolved, called FimH , where PD
contains 10 mutations near the inter-domain interface. Although the
X-ray structures of FimH and FimH are almost
identical, experimental evidence shows that FimH
is activated even in the absence of shear. Here, molecular dynamics
simulations combined with the Jarzinski equality were used to
investigate the discrepancy between the crystallographic structures and
the functional assays. The results indicate that the free energy barrier
of the unbinding process between LD and PD is drastically reduced in
FimH . Rupture of an inter-domain hydrogen bond
involving R166 constitutes a rate limiting step of the domains
separation process and occurs more readily in FimH
than FimH. In conclusion, the mutations in FimH
shift the equilibrium towards an equal occupancy
of bound and unbound states for LD and PD by reducing a rate limiting
step.
Relationship between soil seed bank and forest restoration techniques on areas around bauxite mining environment
Authors: Fonseca Wesley da Silva , Martins Sebastião , Villa Pedro Manuel , Fioresi Enzo Mauro
Published: January 2023

The soil seed bank is one of the most important ecological indicators to
evaluate and monitor the ecological restoration process of plant
communities. We aimed to evaluate the influence of ecological
restoration techniques on the plant community diversity and composition
and functional group composition of the soil seed bank in two bauxite
mining areas under compensatory restoration, Southeast Brazil. 30 soil
samples were collected in each area (Area_A – Forest restoration by
planting seedlings and nucleation techniques and Area_B – just
restoration by planting seedlings). The samples were transported to a
shade house and evaluated for six months, where germinated individuals
were counted and identified weekly. The results indicated that the soil
seed banks of the two areas are floristically similar (with a
predominance of pioneer, herbaceous and native origin species), which
show a higher natural regeneration potential. However, the higher
species richness and abundance of zoochoric individuals in Area_A
demonstrate that nucleation techniques, such as topsoil transposition
and direct seeding were efficient to increase the recovery potential
re-establishment. In the early successional stages, restoration
techniques are more determinant in the functional group composition than
in the floristic composition of the soil seed bank.
An environmentally-driven two-strain mutualistic coinfection model with coupling transmission in vivo and vitro and humoral immunity
Authors: Zhang Long , Zhang Yuru , Sang Yuan , Song Bing
Published: January 2023

In this paper, a coupling transmission epidemic model with mutualistic
two-strain of virus in body and vitro of host is proposed, in which
humoral immune response only works for strain 1 due to immunity evasion
of mutation. For the within-host subsystem, the global stability of all
feasible equilibria with and without environmental influence are
discussed. For the between-host subsystem, the basic reproduction number
R 0 is obtained. When R 0 < 1 , the disease-free equilibrium
is local stable, while the endemic equilibrium is local stable and the
disease is uniformly persistent if R 0 > 1 . Meanwhile,
backward bifurcation would occur when there exists immune response
within host. Finally, numerical examples are provided to illustrate
obtained conclusions, by which we find that the mutualism between two
strains during co-infection leads to a more persistent disease than
single strain, even the basic reproduction number is small than 1 in
each single strain.

Authors: yangying xu , Yang Feng , Li Duan , Xue Wei , Zhang Huimin , Liu Yingxue , Dou Huaiqian , Hao Cuifang
Published: January 2023

Objective: To assess the influence of vaccination on
reproductive outcome treatment of in vitro fertilization (IVF)
treatment. Design: A retrospective cohort study.
Setting: A university-affiliated reproductive medical center.
Population: The study included a total of 1105 couples who
underwent 1269 IVF treatment cycles with fresh cycles from March.1.2021
to January.1.2022. 215 vaccinated couples, 677 unvaccinated couples, 101
couples with female vaccinated only, and 112 couples with male
vaccinated only. Methods: 1105 couples were divided into four
groups according to the inactivated COVID-19 vaccination status of both
partners: Group A, both partners were vaccinated; Group B, only female
partners were vaccinated; Group C, only male partners were vaccinated;
Group D, neither of them was vaccinated. To compare the live birth and
neonatal outcomes among different vaccinated couples or unvaccinated
couples. Main Outcome Measure(s): The primary outcome was a
live birth rate and secondary outcomes were a low birth rate and preterm
birth rate. Result(s): The results showed that there are no
significant differences in live birth rate and neonatal outcomes among
different groups. The logistic regression model applied demonstrated
that the different vaccination statuses of infertile couples had no
effects on the live birth rates. Conclusion(s): The COVID-19
inactive vaccine did not affect the couples’ reproductive outcome in IVF
treatment. To prevent serious complications related to COVID-19
infection during pregnancy and the perinatal period, active immunization
with vaccines is available before pregnancy.
Fentanyl-induced respiratory depression is independent of β-arrestin2 signaling
Authors: liu wei , Liang Xiaonan , song song mengran , Yong Zheng , Su Ruibin
Published: January 2023

Background and Purpose: β-arrestin2 plays an important role in opioid
receptor signaling, but its involvement in morphine- and
fentanyl-induced respiratory depression is widely debated. The aim of
this study was to determine whether β-arrestin2 signaling is associated
with fentanyl- and morphine-induced respiratory depression. Experimental
Approach: This study investigated whether β-arrestin2 is involved in
respiratory depression induced by fentanyl or morphine by inhibiting the
upstream signaling molecule GRK2 and knocking out β-arrestin2 in mice,
using whole-body plethysmography chambers to assess changes in
respiratory function. Key Results: In the experiment of inhibiting GRK
molecules, GRK inhibitors significantly improved the respiratory
depression induced by morphine, but had no effect on fentanyl. In
experiment of knocking out β-arrestin2, respiratory depression was
significantly improved in the morphine group, but less affected in the
fentanyl group. Conclusion and Implications: Our results suggested that
inhibition of β-arrestin2 signaling alleviated morphine-induced
respiratory depression but had little effect on fentanyl-induced
respiratory depression in both models, suggesting differences in the
respiratory depression mechanisms between fentanyl and morphine. This
suggests that we may need to give a differentiated dosing regimen in
clinical treatment of respiratory depression caused by the two drugs.
Trade models in the European Union
Authors: Gräbner-Radkowitsch Claudius , Tamesberger Dennis , Heimberger Philipp , Kapelari Timo , Kapeller Jakob
Published: January 2023

By studying the factors underlying differences in trade performance across
European economies, this paper derives six different ?trade models? for 22
EU countries and explores their developmental and distributional dynamics.
We first introduce a typology of trade models by clustering countries on the
basis of four key dimensions of trade performance: endowments, technological
specialisation, labour market characteristics and regulatory requirements.
The resulting clusters comprise countries that base their export success on
similar trade models. Our results indicate the existence of six different
trade models: the ?primary goods model? (Latvia, Estonia), the ?finance
model? (Luxembourg), the ?flexible labour market model? (UK), the ?periphery
model? (Greece, Portugal, Spain, Italy, France), the ?industrial workbench
model? (Slovenia, Slovakia, Poland, Hungary, the Czech Republic), and the
?hightech model? (Sweden, Denmark, Netherlands, Belgium, Ireland, Finland,
Germany and Austria). Subsequently, we provide a comparative analysis of the
economic development and trends in inequality across these trade models.
Inter alia, we observe a shrinking wage share and increasing personal income
inequality in most of them, yet find that the ?high-tech model? is an
exceptional case, being characterised by relatively stable economic
development and an institutional setting that managed to counteract rising
inequality.
What do state-owned development financial institutions (SODFIs) in South Africa do?
Authors: Adebayo Adeyemi
Published: January 2023

This study explores the model of state-owned development financial
institutions (SODFIs) in South Africa and how South African SODFIs
contribute to national, continental, and international developmental agendas
by providing necessary support towards financing domestic and international
projects, thereby mitigating seven categories of market failures. It
analyses relevant documents and the latest annual/integrated reports of the
SODFIs, making it possible to highlight their modus operandi and the
instruments employed in fulfilling their mandates. Analyses indicate that
although SODFIs in South Africa mitigate market failures by adequately
contributing to national, continental, and global developmental agendas,
they do not fund state-owned enterprises (SOEs), leaving out an important
aspect of public socioeconomic cooperation. This study thus highlights the
importance of funding SOEs partly through SODFIs rather than directly from
the national budget and discusses implications for theory and practice.
Gynecologic oncology surgical procedures in the General hospital ”dr. Radivoj Simonovic” in Sombor in the period from 2011-2021
Authors: Djurdjevic Srdjan , Racic Lazar , Zakula Milan
Published: January 2023

Introduction. In the period from 2011 - 2021, 1482 gynecologic surgeries were performed at the Department of Gynecology and Obstetrics of the General Hospital in Sombor, of which 50 (3.4%) were gynecologic oncology surgical procedures. The distribution of the malignant tumor localization was as follows: vulva 4 (8%), cervix 13 (26%), endometrium 24 (48%), and ovary 9 (18%). Material and Methods. The preoperative diagnosis of all patients included standard laboratory tests of blood and urine, chest X-ray, internal medicine specialist examination, electrocardiography, and imaging procedures (magnetic resonance imaging or computed tomography) of the small pelvis and abdomen. In all cases, the diagnosis of vulvar, cervical, and endometrial cancer was made preoperatively, based on pathohistological findings of the biopsy samples of tumor tissue or material obtained using exploratory curettage. In ovarian cancer, the diagnosis was made during surgery based on ex tempore pathohistological analysis. Results. Most of the operated patients were in the International Federation of Gynecology and Obstetrics stage I - 39 (78%) and the most common pathohistological type of tumor was adenocarcinoma of different localizations - 29 (58%). The number of lymph nodes removed per surgery was 16 - 39 (x: 19) and lymphovascular invasion was present in 31 (62%) operated patients. Intraoperative complications (bleeding, ureteral injury, infection, and wound dehiscence) occurred in 8 (16%) patients, recurrence occurred in 3 (6%), and postoperative lethal outcome occurred in 4 (8%) patients. Conclusion. The essential condition for performing gynecologic oncology surgical procedures in a secondary level healthcare facility is a well-trained gynecology surgeon who has received complete training in gynecologic oncology at the tertiary level, as well as the optimal number of gynecologic oncology surgeries in accordance with recommendations of the European Society of Gynecological Oncology.

Published: January 2023

Introduction. Musculoskeletal pain is one of the most common types of pain
affecting muscles, bones, joints, ligaments and tendons. The aim of this
study was to determine the differences in the prevalence of musculoskeletal
pain between students of sports and physical education and health care
students. Material and Methods. The cross-sectional study included a total
of 50 students, of whom 25 (50%) were students of sports and physical
education, and 25 (50%) were students of health care. Data on the
musculoskeletal system of students were collected through a questionnaire
for the analysis of musculoskeletal symptoms. Results. The results showed
that the neck and upper back pain was not negligible (14 respondents, 28%)
as well as the lower back pain (27, 54%). Based on the Chi-square test, it
was concluded that low back pain was significantly more common in students
of health care (c2 = 3.945; p = 0.047 < 0.05) than in students of sports and
physical education. Also, neck pain was significantly more common in health
care students (c2 = 6.349; p = 0.012 < 0.05). Conclusion. Based on the
obtained results, it can be concluded that students mostly presented with
low back pain, followed by the neck and upper back pain. Engaging in proper
exercises on weekly basis and excess weight reduction can prevent low back
pain.

Published: January 2023

Introduction. Two-thirds of patients with congenital pulmonary airway
malformation are asymptomatic at birth, but during life they may develop
symptoms such as recurrent respiratory infections. The purpose of this paper
is to present three cases of adult patients in whom congenital pulmonary
airway malformation was diagnosed and treated at the Institute for Lung
Diseases of Vojvodina, along with the clinical course of the disease and the
therapeutic procedure. Case Report 1. A 24-year-old female with a medical
history of asthma and recurrent signs of lower respiratory tract infections
was referred to a thoracic surgeon. Computed tomography of the chest and
clinical features were consistent with a congenital lung disease. A left
lower video-assisted thoracoscopic lobectomy was performed.
Histopathological analysis confirmed type II congenital pulmonary airway
malformation with pulmonary sequestration. Case Report 2. A 41-year-old male
with a history of left-sided spontaneous pneumothorax at the age of 16 was
referred to a thoracic surgeon due to moderate hemoptysis, one month after
hospital treatment of left-sided bronchopneumonia. On chest computed
tomography, multiple cystic lesions were found in the left lower lung lobe.
Thoracotomy and left lower lobectomy were performed. Histopathological
analysis confirmed type I congenital pulmonary airway malformation. Case
Report 3. The third patient was a 16-year-old male with a history of
juvenile asthma and recurrent right-sided bronchopneumonia. Sings of
necrotizing pneumonia, lung abscess, and mediastinal lymphadenomegaly were
found in the affected lobe. Thoracotomy and right lower lobectomy were
performed. Histopathological analysis confirmed type II congenital pulmonary
airway malformation. Conclusion. In children and young adults with recurrent
small airway inflammation, congenital lung malformation should be considered
in the differential diagnosis.

Published: January 2023

Introduction. Delirium is defined as an acute change in mental status that
leads to disturbance in perception, thinking, memory, attention, emotional
status, as well as sleep rhythm disorders and is most often reversible.
Postoperative delirium is an acute mental disorder that develops after
cardiovascular surgery with an incidence of 20 - 50% of operated patients.
This complication is associated with a longer hospitalization, longer stay
in the intensive care unit, as well as increased morbidity and mortality.
Risk Factors. The risk factors are divided into preoperative, intraoperative
and postoperative. The most common preoperative risk factors are older age,
stenosis of the carotid arteries, previous cerebral diseases, depression,
diabetes, hypertension, low ejection fraction of the left ventricle, as well
as heart rhythm disorders. Intraoperative risk factors include the type of
surgery, type of anesthesia, duration of extracorporeal circulation, and
duration of aortic clamp. The most important postoperative risk factors
include the use of psychoactive drugs, prolonged pain, the use of opioid
drugs, duration of mechanical ventilation, and the length of stay in the
intensive care unit. Prevention. Prevention is a very important aspect that
is most often focused on intraoperative and postoperative precipitating
factors. Preventive treatment includes pharmacological and
non-pharmacological methods. The main recommendation refers to avoiding
routine use of antipsychotics. Conclusion. Continuous infusion of
dexmedetomidine compared to propofol reduces the incidence of postoperative
delirium. Nonpharmacological approach consists of a series of procedures
that are carried out postoperatively, such as the protocol that includes
monitoring of Awakening, Breathing, Coordination, Delirium, Early mobility,
and Family engagement.

Authors: Kunduraci Tugce , Elmali Ceren , Ugur Tamer
Published: January 2023

In this study, n-point graphs and n-point texture spaces are examined and
graphs that we will call Texture Graphs are obtained. In addition, it is
shown how a di-topology can be obtained on the given texture space with the
help of this graph. It is shown that a di-topological texture space (S,S,?,k)
associated with di-graph (S,G) and each di-graph (S,G) with n points
associated with a unique di-topology on texture space. With the graph
obtained from co-topology, it has been seen that there is alternative
information for the solution of many mathematical and non-mathematical
problems in terms of application.
on approximation sine wave with the 5th and 7th order Bezier paths in plane
Authors: Kilicoglu Seyda
Published: January 2023

There are many studies to approximate to sine curve or sine wave. In this
study, it has been examined the way how the sine wave can be written as any
order Bezier curve. First, it has been written the 5th and the 7th degree
Maclaurin series expansion of the parametric form of sine curve. Also, they
are 5th and the 7th order Bezier paths, based on the control points with
matrix form in E2. Hence it has been given the control points of the 5th and
the 7th order Bezier curve based on the coefficients of the 5th and the 7th
degree Maclaurin series expansion of the sine curves in three steps.
Further it has been given the coefficients based on the control points of
the 5th and the 7th order Bezier curve too.

An application of the intuitionistic fuzzy PROMETHEE method in the selection of transportation service
Authors: Citil Mehmet
Published: January 2023

Many of the problems we encounter involve uncertainties. Intuitionistic fuzzy
logic works well in solving problems with uncertainties. Transportation
problems, which are needed find the most appropriate and best, also contain
uncertainty. A solution is found by using one of the decision making methods
by determining the weight values of the criteria. The PROMETHEE method has
an important place among the multi-criteria decision-making methods as it
allows the decision maker to observe both positive and negative rankings.
We may solve problems with uncertainties through using intuitionistic fuzzy
logic. In this study, a new and different solution method is presented to
find the most suitable transportation service provider by using the
intuitionistic fuzzy PROMETHEE method. Criterion weight values were
determined by controlled sets. Decision makers may apply this method to
their problems by changing the weights we use depending on the importance of
their criteria.
