This study is to investigate the morphology and electrical characteristics of single-wall carbon nanotubes (SWCNTs) thin film deposition using air brush technique. A deposition setup consisting of a conventional artist air brush was developed and used to deposit SWCNT thin films and therefore the resulting film’s characteristics need to be investigated to gauge its suitability in producing uniform monolayer. The SWCNTs used were synthesized via Direct Injection Pyrolytic Synthesis (DIPS) method, with diameters ranging from 0.8 to 3 nm. The substrate was deposited using an airbrush with varying nozzle to study its effect to the resulting SWCNTs thin films’ characteristics. Subsequently, scanning electron microscope (SEM) were used to inspect the morphology and surface topography, and followed by preliminary electrical measurements. The result shows that good dispersion promotes uniform distribution of SWCNTs over large area of glass substrate. Moreover, the electrical measurement revealed that at 1 V, best morphology produced highest current at a nozzle distanceof 10 mm (15.3 μA) and the lowest current at a nozzle height of 4 mm (3.24 μA). From the results presented, it is demonstrated that conventional artist airbrush setup can be effectively used to deposit monolayer thin film of SWCNT with high degree of uniformity. This research is necessary for the process of depositing-controlled CNT thin film network, which can influence the material characteristics and performance of the variety of CNT-based device applications.

Gastronomic heritage is undergoing significant developments, creating a need for competitive strategies to develop food tourism in certain regions. The research explores food culture and tourism in three case studies of Latvia, Romania, and Italy. The article focuses on the information about gastronomic heritage that food lovers request, and the critical components required at a destination for food tourism to flourish. A survey of people involved in gastronomic tourism (151 in Romania, 112 in Italy, 126 in Latvia) using a simple random sample. Based primarily on respondent observations, descriptive and qualitative analysis and nonparametric method are used to explain the phenomenon. SPSS software (26 version) was used to analyze the statistical data. The findings show that people need of information and a new kind of interaction between tourist/consumers and home producers that they can trust. Many of the information are hidden and there is a lack of voice about the gastronomic heritage specially on home producers. The promotion of home producers could be successful if emphasis is placed on attracting tourists and on their visits to home producers, as well as on attracting tourists from abroad. In different countries does not actively promote the opportunity to experience at home producers. A digital food resource and the role of home-organized markets is encouraged in destinations that is promoted to focus the lens on the gastronomic heritage and all its experiences.

Published: November 2022

The COVID-19 pandemic has affected the world socially, culturally, economically, and politically. Struggling with the COVID-19 virus has become the focal point of the countries. As many studies are being conducted, and new treatment methods are being discussed, the vaccination process continues worldwide. According to the current statistics, 63% of the world population has been already fully vaccinated. During this period, along with the true information, many false information facts and materials proliferated which lead to the reluctance of individuals to be vaccinated. As a result of
it, the virus exposes to mutation and more serious cases emerge worldwide. In this context, this study aims to analyze false information Tweets regarding vaccination in Turkey. As Turkey is one of the top countries with the highest cases and the medium-scaled (68%) level of vaccination worldwide, the study findings will help to understand the main motives of anti-vaccination by focusing on false facts. A two-step methodology was followed in the research. First, data collection was done through Twitter API and then, the analysis was conducted using the Orange Data Mining Program and content analysis. Propaganda is one of the interesting results as the most-shared false information type. On the other hand, while “the denial of the epidemic” was the most-focused theme, “stop insisting on PCR” and “pandemic is over” were the most-emphasized discourses in the Tweets.

Authors: Ayşe Ateş  , Bahşi Niymet
Published: November 2022

Emotional intelligence is expressed as a person's ability to differentiate between oneself and other's emotions, to perceive them, and to act accordingly. The emotions left in the background by the education world, which are based on cognitive skills, have started to take place in education from the perspective of emotional intelligence in recent years. This study aims is to determine the effect of emotional intelligence of foreign students learning Turkish language on speaking and writing anxiety. In this direction, within the framework of emotional intelligence, the effect of teaching Turkish as a foreign language on speaking and writing anxiety has been studied and various determinations have been made. This study is a quantitative study and the method of the research is descriptive field research. The study group consists of 173 volunteers who studied at Inonu University TOMER in the academic year of 2018-2019. It was determined that the emotional intelligence writing and speaking anxiety levels of the students were at an average level. It was determined that as the emotional intelligence levels increased, speaking and writing anxiety decreased in the result of the analysis. In addition, as the duration of the students' stay in Turkey increased, there was an increase in the speaking anxiety level, while no significant difference was shown in the writing anxiety level.
Increased belief in vaccination conspiracy theories predicts increases in vaccination hesitancy and powerlessness: Results from a longitudinal study
Authors: Coelho Priscila , Foster Katrina , Nedri Meriam , Marques Mathew daCosta
Published: November 2022

Rationale: Vaccinations are an important part of a public health strategy against preventablediseases, and uptake is influenced by factors including hesitancy. The belief of vaccinerelated misinformation including anti-vaccination conspiracy theories has been found to beassociated with increased vaccine hesitancy.Objective: While research suggests that these conspiracy theory beliefs may arise to satisfyunmet needs such as restoring loss of personal control, somewhat ironically these antivaccinationconspiracy theories may frustrate these needs. This study examined the causalrelationships between vaccination hesitancy, vaccination conspiracy theories, and vaccinationrelated powerlessness.Methods: Using a stationary random intercepts cross lagged panel model, we investigated thetemporal ordering of vaccination hesitancy, powerlessness, and vaccination conspiracy theorybeliefs in a sample of Australian adults (N = 500) in a longitudinal study with 5-timepointsover 4-months between June and October 2021.Results: Results from a random intercept cross-lagged model, that separates between-personstability from within-person change, suggested that increased belief in vaccination conspiracytheories was associated with future increases in vaccination hesitancy and powerlessness (butnot vice versa). Findings also showed that increases in vaccination hesitancy and conspiracytheory beliefs predicted respective increases from a person’s trait-level mean at subsequenttimepoints.Conclusions: Vaccination conspiracy theories appear to increase vaccination powerlessnessand hesitancy, rather than satisfying an unmet need for personal control.
Adoption of Virtual Assistants for Human-Computer Interaction among Smartphone Users in Lagos, Nigeria
Authors: Iyinolakan Olayinka
Published: November 2022

Steady advancements in digital technologies are facilitating human-machine interaction to rival human conversations in many societies. Human-machine exchanges have received further boosts through Artificial Intelligence (AI) powered virtual assistants (VA) in intelligent devices such as Siri, Cortana, Alexa and Assistant. As mobile devices spread within African communities, beyond urban areas to rural communities, an increasing demand exists to integrate African communications systems into the global digital ecosystem. Given that most African languages are expressed orally, AI and virtual assistants could be the key to facilitating inclusive communication. This study utilised a pragmatic mixed research method to evaluate how Nigerian smartphone users in Lagos currently use and accept AI-powered voice-enabled virtual assistants. Using SPSS and Nvivo to analyse surveys of 357 persons and nine interviews and deducing from the media richness and the uses and gratifications theories, results show that virtual assistant awareness in Lagos is low. However, those who use using the tools find richness and satisfaction in interacting with VAs to carry out communications tasks. Current challenges exist that pertain to accents, internet access and localised languages. To ensure that voice-enabled VAs can truly solve financial and educational inclusion challenges across Nigeria, further extensive studies are needed using a wider population.

Authors: Pyar Khin Phyu
Published: November 2022

Background: Coronavirus disease 2019 (COVID-19) has been threatening the world for more than 2 years. Breakthrough COVID-19 infection has clinical and public health significance. The health care workers have been working in front line; thus, acquiring greatest risks. Their family members are also at high risk being close contact to them. This study aimed to assess the prevalence and the severity of breakthrough COVID-19 infection (BTI) in fourth wave among health care workers (HCW) and their family members, and the protective effect of C OVID-19 vaccine in Myanmar. Methods: A cross-sectional descriptive study was conducted among health care workers (HCW) and their family members who developed confirmed COVID-19 infection either by rapid test or PCR test at least 14 days after receiving COVID-19 vaccine during the fourth wave from January 2022 to May 2022. Data were collected by using standardized forms and analysis was done. Results: A total of 1013 participants were included in this study; 227 HCW and 786 family members. Less than half of HCW 44.4% (101/227) and 17.1% (135/786) of family members suffered BTI in fourth wave. Among them, 95% (96/101) of HCW and 57% (76/135) of family members had at least 3 doses of vaccine. The the chances of getting BTI after taking 3 doses, 4 doses and 5 dose were 47.4%, 36.1% and 10% respectively in HCW; and, 32.8%, 22.4% and 1% respectively in the family members. The mean duration of last dose of vaccine to symptom onset was 45.9 ± 40.6 days in HCW and 60.7 ± 66.6 days in the family members. The proportion of different types of vaccine received by HCW were Covaxin 88%, Sinopharm 70%, Covishield 34% and Sputink V 30% whereas the proportion in their family members were Covaxin 27%, Sinopharm 68%, Covishield 56% and Sputink V 13%. Comorbid status was noted in 15% of HCW and 45% of family members. The prevalence of breakthrough hospitalization was 3 (3.1) HCW and 8 (6.4%) family members. The survival rate was 100% in HCW and 97% in family members. Non survivors were over 65 years and they had multiple comorbidities. Half of them received only 2 doses of vaccine; one was unvaccinated. Conclusions: The majority of cases with BTI in fourth wave was mild. The prevalence of breakthrough hospitalization was 3-6% in HCW and family members; showing the protective effect of vaccine from severe manifestation. Non-survivors were elderly, having multiple comorbidities and incomplete vaccination or unvaccinated. The chance of BTI was decreasing if they obtained 4 doses compared to 3 doses. The possibility of BTI after taking 3 doses of vaccine was 50% in HCW and 33% in family members; it dropped to 36% and 22% respectively after 4 doses of vaccine. Therefore, 3 doses of COVID-19 vaccine could protect 50-67 percent; the protective efficacy increased to 65-87 percent with 4 doses. Therefore, 4 doses of COVID-19 vaccine are recommended for prevention of fifth wave in Myanmar.
Clinical case: second mandibular premolar with three root canals
Authors: V. Vusataya Elena.
Published: November 2022

The effectiveness and success of endodontic treatment depends on the doctor's professionalism and knowledge of the anatomy and morphology of root canals. The equipment that is at the disposal of the dentist is also of great importance. At the moment, it is difficult to imagine the diagnosis of complex endodontic pathology without the use of cone-beam computed tomography. Diagnostic radiographs in different projections are important for getting an idea of the number of existing root canals, but do not always give a complete picture of the anatomy and morphology of root canals. Magnifying devices (binoculars and dental microscope) are also very helpful for competent treatment in modern dentistry in general and endodontics in particular. Premolars of the mandible are among the most difficult teeth for endodontic treatment due to a sufficient number of variations in internal morphology, the presence of additional root canals, apical deltas and lateral canals.
A Clinical Approach of Lupus Nephritis Associated with Catastrophic Antiphospholipid-Antibody Syndrome Review and Case Report
Authors: Stoian Marilena
Published: November 2022

Glomerulonephritis is a major cause of morbidity in systemic lupus erythematosus (SLE). In fact, immune complex formation and deposition in the kidney results in intraglomerular inflammation with recruitment of leukocytes, and activation and proliferation of resident renal cells. Intense injury may destroy resident renal cells by necrosis or apoptosis resulting in fibrinoid necrosis. When injury is less intense, endocapillary cells respond by proliferating and production of extracellular matrix (proliferative lesions). Renal biopsy, examination of urine sediment and measurement of C3 levels (and to less anti-DNA titers) are essential for the management of lupus nephritis. Treatment depends on the severity of the lupus nephritis. Disease severity depends on the presence or absence of high-risk factors. These include demographic (male gender, black race), clinical (failure to achieve response or marked delay in response, multiple relapses, pregnancy), laboratory (impaired renal function, severe anemia with hematocrit less than 26%) and histologic features (mixed membrane- proliferative or proliferative nephritis; cellular crescents and/or fibrinoid necrosis; cellular crescent and/or fibrinoid necrosis; and moderate to high degrees of interstitial fibrosis and/or tubular atrophy).

The purpose of the article is to analyze the features of conducting a small laboratory workshop as a means of studying the course of organic chemistry without the use of reagents included in the list of narcotic drugs, psychotropic substances andprecursors.

During the writing of the article, such methods of scientific research as analysis, synthesis, comparison, generalization were used - to find out the state of solving the researched problem in the theory and methodology of teaching chemistry, to determine the theoretical foundations of the research, as well as a chemical experiment - to conduct experimental research and proving the effectiveness of theoretical assumptions.

Based on the analysis of literary sources, the tasks, main functions and requirements for a chemical experiment in the process of learning organic chemistry are determined. It has been found that the problem of using a chemical experiment tostudy the basic principles of the structure of organic compounds, methods of their synthesis and properties requires further research in order to adapt the methodology of conducting experiments to the conditions under which the use of precursors andtoxic substances is limited. The greatest attention was focused on methodological aspects of reproduction and description of experiments on the oxidation of organic compounds, since most of such experiments had to be adapted to the conditions underwhich the use of potassium permanganate is prohibited.

The results of the conducted research showed the possibility of adapting the methods of a small laboratory workshop in organic chemistry to the conditions under which the use of precursors and toxic substances is excluded. As a substitute forpotassium permanganate solution, potassium chromate and potassium dichromate solutions were used and a positive result was obtained. Developed recommendations can be used for research and conducting laboratory work in laboratories ofeducational institutions.
Past Migrations and Their Consequences from a Lifelong Perspective: Reflections of Polish 1980s Migrants
Authors: Dziekońska Małgorzata
Published: November 2022

W dzisiejszym dynamicznym świecie zjawisko migracji ma coraz większy zasięg, jest bardziej złożone i analizowane z wielu perspektyw. Jedną z nich są migracje dawne. W 2020 roku zostało przeprowadzone badanie wśród Polaków, którzy migrowali za granicę w latach osiemdziesiątych XX wieku. Jego wyniki określają nie tylko kolejne punkty widzenia na przeszłe doświadczenia migracyjne, ale przede wszystkim ich konsekwencje w perspektywie całego życia. Zaspokojone wówczas potrzeby finansowe spowodowały znaczną poprawę warunków życia rodzin migrantów, a w wielu przypadkach przyczyniły się również do poprawy ich sytuacji materialnej w późniejszym życiu. Jednak w perspektywie całego życia, niezależnie od korzyści finansowych, migracje te, okazując się zagrożeniem dla szeroko rozumianej stabilności rodziny, zostały ocenione jako życiowy błąd.

El uso de la ventilación mecánica se considera uno de los principales tratamientos de los pacientes que presentan insuficiencia respiratoria grave. Su utilización está ligada entre un 30 % a 50 % de casos en las unidades de urgencia y de cuidados intensivos, lo que la convierte en una herramienta útil, empleada para brindar soporte en la función respiratoria y cardíaca. Sin embargo, esta técnica no se encuentra exenta de presentar riesgos y complicaciones que podrían considerarse potencialmente letales para el paciente. La presente revisión bibliográfica se realizó con la finalidad de identificar las complicaciones asociadas al manejo de la vía aérea en pacientes con ventilación mecánica invasiva. Se efectuó una investigación cualitativa en la que se incluyen artículos científicos publicados en revistas indexadas de alto impacto desde el año 2018 hasta el año 2022 y de acuerdo a su alcance se identificó como una investigación de tipo descriptiva. En efecto, las complicaciones relacionadas con el manejo de la vía aérea en pacientes con ventilación mecánica se asocian a lesiones pulmonares como: volutrauma, barotrauma y atelectrauma. Asimismo, se ocasionan debido a infecciones pulmonares y neumonía asociada a la ventilación mecánica. También se producen como consecuencia de complicaciones asociadas con el circuito mecánico y el aislamiento de la vía aérea.

Este estudo analisa o nível de homogeneidade entre os indicadores sociais divulgados pelos países pertencentes à Comissão Econômica para a América Latina e o Caribe. Analisaram-se os indicadores sociais do período de 2010 a 2012 disponibilizados pelo Instituto Brasileiro de Geografia e Estatística de 18 dos 44 países membros, com aplicação da Análise de Correspondência. Os resultados mostram que as variáveis selecionadas encontram-se agrupadas em duas dimensões, Qualidade de vida e Qualidade nutricional. Identificaram-se quatro grupos com características homogêneas no mapa perceptual de categoriais das variáveis e quatro grupos de países com características similares em seus indicadores sociais no mapa perceptual de objetos por países.
EMPREENDEDORISMO E SUAS IMPLICAÇÕES NA INOVAÇÃO E DESENVOLVIMENTO: UMA ANÁLISE MULTIVARIADA COM INDICADORES SOCIOECONÔMICOS.

Published: November 2022

O presente trabalho tem como objetivo analisar a relação entre desenvolvimento econômico e social e o nível de atividade empreendedora no mundo. Para atingir ao objetivo foi analisado se o nível de atividade empreendedora e se o empreendedorismo por oportunidade influencia no desenvolvimento econômico na competitividade e no desenvolvimento social de um país. Foram analisados dados de 65 países no ano de 2014 e como proxy para desenvolvimento econômico foi empregado a Renda per capita, para competitividade foi utilizado o Índice de Competitividade Global (CGI) e para desenvolvimento social foi procedido o Índice de Desenvolvimento Humano (IDH). Os dados foram modelados a partir de estatística multivariada, sendo trabalhados 4 modelos, 3 de regressão linear múltipla estimados pelo método dos mínimos quadrados ordinários e um de regressão logística estimado pelo método enter. Os resultados confirmaram as hipóteses levantadas pela pesquisa, evidenciando que a taxa de empreendedorismo total está relacionada inversamente com os indicadores de desenvolvimento econômico, social e competitivo de um país. Não obstante, quando verificado o empreendedorismo por oportunidade, este demonstrou forte relação positiva com o nível de desenvolvimento dos países, sugerindo que o empreendedorismo por oportunidade impulsiona a inovação nos negócios e o consequentemente o crescimento econômico.
Destinos Indutores de Turismo Regional como Política de Governabilidade Estadual no Brasil: Análise dos Estados de Minas Gerais e Bahia a partir do Índice Firjan de Desenvolvimento Municipal (IFDM)

Published: November 2022

O Plano Nacional de Turismo do Brasil indica a descentralização de práticas governamentais da União para os Estados. Porém, entre os 27 estados da federação, apenas dois apresentam uma agenda política de destinos indutores, os quais são os estados de Minas Gerais e Bahia. Vários trabalhos acadêmicos relacionam turismo e desenvolvimento, mas nenhum realiza tal distinção no âmbito estadual. Assim, estabelecemos dois objetivos essenciais neste estudo: comparar o indicador socioeconômico (Índice Firjan de Desenvolvimento Municipal - IFDM) entre cidades indutoras e não indutoras nos dois Estados e; analisar características e diferenças de governança da política entre eles. Ficou constatado que, destinos indutores possuem maior desenvolvimento socioeconômico; o programa do Estado de Minas é mais técnico-científico, o do Estado da Bahia é mais informativo.

Published: November 2022

Este artigo objetivou investigar como a experiência internacional interfere na percepção da distância psíquica entre o Brasil e outros seis países. Para tanto, entrevistou-se seis pessoas com experiência internacional e seis sem experiência, buscando identificar as percepções convergentes e divergentes. O estudo possui caráter descritivo e natureza qualitativa, baseando-se nos modelos teóricos de Rocha (2004) e Hofstede (1980). Os dados foram analisados conforme a técnica de análise de conteúdo. Os resultados possibilitaram comprovar empiricamente a influência da experiência internacional na percepção da distância psíquica, e revelar as associações equivocadas que os entrevistados cometem por falta de conhecimento sobre os países.

Published: November 2022

Este trabajo pretende analizar la influencia de la Responsabilidad Social Empresarial (RSE) en los Resultados Empresariales (RE) en las micro, pequeñas y medianas empresas (Mipymes). Para ello se propone un modelo utilizando datos de los informes de sostenibilidad de 278 Mipymes españolas confeccionados bajo los estándares de GRI. Para el contraste de las hipótesis y la obtención de resultados se ha utilizado software SmartPLS 3.2.3. Los resultados nos permiten afirmar que las Mipymes también desarrollan actividades de RSE y que aquellas Mipymes que las llevan a cabo mejoran sus resultados.
