Published: October 2023

Abstract Aedes aegypti L. (Diptera: Culicidae) is the main transmitter of pathogens that cause human diseases, including dengue, chikungunya, zika and yellow fever. Faced with this problem, this study aims to select fungi with entomopathogenic potential against Ae. aegypti and develop formulations that optimize the control action of entomopathogenic fungi in the semi-field condition. 23 fungal strains native from Amazon were inoculated in Potato-Dextrose-Agar (PDA) culture medium for 14 days and then transferred by scraping to tubes containing 0.9% NaCl solution. To obtain the larvae, eggs were collected using traps in peridomestic environments for 7 days. 20 larvae of Ae. aegypti in 125 mL erlenmeyers containing 20 mL of conidial suspension at a concentration of 1x106 conidia/mL for initial selection and 1×104, 1×105, 1×106 and 1×107 conidia/mL for determination of LC50. Mortality was checked every 24 h for 5 days. The three fungi with the best virulence rates were identified using molecular techniques. The compatibility between fungi at a concentration of 1×106 conidia/mL and oily adjuvants, mineral oil and vegetable oil (andiroba, chestnut and copaiba) at concentrations of 0.1, 0.5 and 1% was evaluated. The germination capacity of 100 conidia per treatment was evaluated after incubation at 28 ºC for 24 h. To evaluate the entomopathogenic potential of the fungal formulations, conidial suspensions (1×106 conidia/mL) were added with 0.1% mineral and vegetable oil. The treatments were submitted to laboratory and semi-field conditions and mortality was verified every 24 h for 5 days. Beauveria sp. (4,458) (LC50 = 8.66× 103), Metarhizium anisopliae (4,420) (LC50 = 5.48×104) and M. anisopliae (4,910) (LC50 = 1.13×105) were significantly more effective in the larval control of Ae. aegypti, in relation to the other fungal morphospecies evaluated. Mineral oil was better compatible in all treatments evaluated. Beauveria sp. (4,458) was considerably less virulent under semi-field conditions. M. anisopliae (4,910) formulated with mineral oil increased larval mortality to 100% on the 4th day in the laboratory and on the 5th day in the semi-field. Fungal formulations developed from native Amazonian isolates represent a promising tool for the development of strategies to control Ae. aegypti.

Resumo Introdução: A pandemia da Covid-19 repercutiu de forma negativa na saúde mental dos estudantes universitários. Nesse período de incertezas e desafios, o desenvolvimento de resiliência, isto é, a capacidade de lidar com situações adversas e se recuperar, fez-se necessário. Sob a ótica do isolamento social, a espiritualidade se mostra como um recurso importante de ressignificação, podendo exercer impacto positivo na resiliência dos estudantes. Objetivo: Este estudo teve como objetivo identificar o grau de resiliência dos estudantes de Medicina durante o isolamento social causado pela Covid-19 e sua relação com a espiritualidade e fatores pessoais. Método: Trata-se de um estudo transversal misto realizado com estudantes de Medicina de instituições privadas e públicas brasileiras. Os dados foram coletados no período de junho a setembro de 2020 utilizando um questionário com perguntas sobre aspectos sociodemográficos e referentes à opinião acerca de pontos positivos e negativos do isolamento social, a Escala de Resiliência e a Escala de Atitudes Relacionadas à Espiritualidade (ARES). Para exame das respostas abertas do questionário, fez-se uma análise de conteúdo com categorização delas por temas. Resultado: Participaram do estudo 308 estudantes. Os escores médios encontrados demonstraram que os estudantes apresentaram moderada resiliência e alta espiritualidade. Observou-se correlação positiva fraca entre grau de espiritualidade e resiliência. As variáveis que impactaram positivamente tanto a resiliência quanto a espiritualidade foram alto nível de satisfação em estudar para ser médico, alto nível de felicidade com a vida nos últimos meses, maior qualidade de vida durante o isolamento, possuir religião e alta importância atribuída ao fato de ter uma religião. Estudantes do sexo feminino e na faixa etária acima de 25 anos apresentaram maior espiritualidade. Os pontos positivos mais citados estavam relacionados com relações sociais, lazer e desenvolvimento pessoal. Os pontos negativos e as dificuldades mais frequentes foram saúde mental-física-social e ensino remoto/adaptação a uma nova rotina. Conclusão: O estudo sugere que estudantes que apresentam maior espiritualidade são mais resilientes, sendo mais capazes de lidar com fatores estressores, adaptar-se e ter uma visão positiva em relação a situações adversas. Esses resultados podem contribuir para uma reflexão sobre estratégias educacionais que visem auxiliar os estudantes no enfrentamento de situações estressoras, como a vivenciada em decorrência do isolamento social.

Abstract Objectives: This study aimed to estimate the prevalence of Common Mental Disorders (CMD) among medical students and identify the factors associated with this disorder. Methods: A cross-sectional study was conducted with all medical students, enrolled from the 1st to the 8th semesters in a public university, in the state of Bahia, Brazil. We used a self-administered questionnaire that included SRQ-20 (Self-Reporting Questionnaire), IPAQ (International Physical Activity Questionnaire - long form) and sociodemographic, school, occupational and health variables. The multivariate analysis was performed using COX Regression for cross-sectional studies. Results: We evaluated 556 students (289 women and 267 men), representing 90.2% of the target population. The overall prevalence of CMD found was 53.3%, 78.8% of students reported feeling nervous, 56.8% experienced poor sleep quality, and 6.5% had suicidal thoughts. After the multivariate analysis, the following factors maintained their association with a higher prevalence of CMD: having no previous undergraduate degree (PR=1.49), having an unfavorable self-perception of health (PR=1.53), not having failed disciplines (PR=1.20), and being a smoker (PR=1.19). Physical activity did not have a protective effect on CMD in this study. Conclusions: The prevalence of CMD among medical students was high and mainly associated with an unfavorable self-perception of health. The results highlight the need for strengthening institutional policies aimed at preventing psychological distress among students.

Published: October 2023

Resumo Introdução: O conceito de deficiência relaciona-se às limitações socialmente impostas aos deficientes por seus corpos não corresponderem ao modelo aceito como normal. Em geral, o acesso à saúde dessa população é precário, em parte, pela falta de preparação voltada ao cuidado dos pacientes deficientes durante a formação médica, demonstrando que os currículos das faculdades necessitam de revisão. Objetivo: Este estudo teve como objetivo analisar a percepção do aluno interno do curso de Medicina da Universidade Federal do Ceará (UFC) acerca do modelo curricular atual no contexto da formação médica, especificamente voltado ao atendimento destinado às pessoas com deficiência. Método: Foi disponibilizado um formulário elaborado no Google Formulários, para coletar informações de internos da Faculdade de Medicina (Famed). Depois, realizaram-se entrevistas semiestruturadas via Google Meet mediante questões que objetivaram entender a relação entre futuros médicos e pessoas com deficiências, além da confiança do preparo para o atendimento a tais pacientes. Para exame do material empírico adquirido, utilizou-se a análise de discurso de Rueda. Resultado: Foram entrevistados 13 internos que relataram limitação no aprendizado do estabelecimento da relação médico-paciente em relação a pessoas com deficiência, durante o ciclo básico (do primeiro ao quarto semestre), evoluindo, principalmente, para o internato. Consideraram-se a educação, o entendimento das condições socioeconômicas e culturais do paciente, e a construção de um plano terapêutico executável as qualidades a serem desenvolvidas pelo interno. Quanto aos principais problemas relatados, destacou-se a dificuldade na realização do exame físico e na comunicação. Por sua vez, a ajuda de acompanhantes e o auxílio da equipe profissional foram apontados como aspectos positivos. Percepções referentes ao preparo para atender deficientes foram contrastantes: alguns relataram segurança por capacitações e conhecimentos empíricos, enquanto outros se sentiram inseguros ou incapazes. Percebe-se, também, importante consideração para haver adaptação curricular acerca desse tema, com intervenções nas disciplinas obrigatórias e optativas. Conclusão: Evidenciou-se que os entrevistados sentem dificuldades no atendimento destinado a deficientes, o que sugere alterações no currículo da Famed-UFC.

Published: October 2023

ABSTRACT Objective: To analyze the exercise of professional autonomy of intensive care nurses during times of the new coronavirus pandemic. Method: A descriptive, qualitative study, conducted with 19 nurses from Intensive Care Units of two public hospitals and one private hospital. The information was produced from October 2020 to January 2021, through semi-structured interviews, using content analysis in thematic modality, guided by Eliot Freidson’s Sociology of Professions. Results: Nursesargued that it was difficult, amidst the pandemic, to act with all the prerogatives assigned to them by their social mandate, for various reasons, such as limited knowledge about the disease, fragile teamwork communication, and scarcity of material and human resources. Conclusion: The exercise of professional autonomy is shaped by the confrontation of multiple factors that impact the performance of intensive care nurses, especially in a context of pandemic crisis.

Published: October 2023

Resumo Introdução O lazer é considerado uma ocupação presente nos estudos, avaliações e intervenções da terapia ocupacional. Na América Latina, há poucos trabalhos que se dedicam à construção do entendimento dos profissionais ou suas percepções acerca do lazer. São ainda mais escassos os estudos que correlacionam com a ciência ocupacional o entendimento destes profissionais sobre tal ocupação dentro do campo da saúde mental. Objetivo Conhecer o entendimento de lazer por terapeutas ocupacionais atuantes na saúde mental de serviços públicos substitutivos ao modelo psiquiátrico asilar. Metodologia Esta pesquisa foi qualitativa, descritiva e exploratória, com desenho transversal. Foi utilizado grupo focal e análise temática da informação advinda do processo de construção coletiva de terapeutas ocupacionais, atuantes em serviços públicos de base territorial de urgência em saúde mental, da cidade de Belo Horizonte, Minas Gerais, Brasil, sobre seus entendimentos quanto ao lazer. Resultados Três categorias emergiram: (a) Lazer - prazer; (b) Lazer - livre escolha; e (c) Lazer - transcendência da dureza. Conclusão O lazer é uma ocupação importante para terapeutas ocupacionais atuantes em saúde mental no território; pode encontrar ressonância em práticas que fomentam a contratualidade e autonomia, especialmente ao se aliar aos princípios da ciência ocupacional de valorização do fazer humano em suas variáveis formas de vivenciá-lo. Acredita-se que esta pesquisa possa auxiliar terapeutas ocupacionais e cientistas da ocupação no entendimento do lazer contemporâneo, em diálogo com o cuidado no território e posicionamento antimanicomial.

Abstract Introduction The consumption of tobacco products, from planting to consumption, is responsible for serious health problems, representing a cycle of diseases, poverty and deaths worldwide. This serious public health problem led Brazil to develop, from the 1980s onwards, a set of tobacco control measures, constituting a policy with legislative, economic, communication and educational actions, which has as its foundation the National Program for Control of Tobacco. Tobacco (PNCT). Objective This article is an experience report that is part of a national study carried out between 2020 and 2022, and describes actions through technical visits to tobacco control coordination offices in five states. Method The states were selected according to criteria established by Ditab/INCA, which coordinates the network of the State Program for Tobacco Control (PECT) in the 26 States and Federative Unit of the country. Thus, a State of each region was chosen: Tocantins (North), Paraíba (Northeast), Goiás (Midwest), Rio de Janeiro (Southeast) and Paraná (South). Results Practices were developed to enhance, improve and add technical, political, communication actions, among others, in order to give sustainability to the State Program and, more broadly, the PNCT.

ABSTRACT Objective: To evaluate the axial correction capacity of the 3D brace in treating Adolescent Idiopathic Scoliosis (AIS). Methods: A retrospective study was carried out with 61 patients with AIS who obtained the 3D brace, between 2019 and 2022, in a laboratory that manufactures orthotics and orthopedic prostheses. These individuals underwent independent analysis of radiographic parameters by evaluating vertebral rotation using the Nash and Moe classification. The analyzed radiographs were taken in orthostasis before and after treatment with the 3D vest. Patients were divided into groups I and II-IV according to the Nash and Moe radiographic classification. Corrective capacity was estimated by assessing the degree of vertebral rotation before and after treatment. Results: Of the 61 patients evaluated, 36 (59%) had Nash and Moe grade I, and 25 patients grade II-IV before treatment. After treatment, 13 (21%) had grade II-IV, and 48 had grade I. Of the patients categorized as II-IV, 64% had improvement in the rotational profile. None clinical studies or radiographic parameter was associated with a change in rotational profile other than brace use (p=0.012). Conclusion: In the studied sample, treatment with the 3D vest promoted a change in vertebral rotation according to the Nash and Moe classification. The majority showed improvement in this parameter of evaluation of treatment of AIS. Level of Evidence III; Retrospective Study.

Published: October 2023

Gastric cancer (GC) is a main cause of cancer death in the world, and improving the chemotherapy sensitivity can enhance the chemotherapy efficacy of GC. The study objective is to explore the differential KIF18B expression in GC and its effect on GC chemotherapy sensitivity. The KIF18B expression in GC tissues and adjacent normal tissues was analyzed by real-time quantitative polymerase chain reaction. The relationship between differential KIF18B expression and different clinicopathological features was detected. It was found that KIF18B was highly expressed in GC tissues, and KIF18B expression was differential in patients with different clinicopathological features. The upregulation of KIF18B has a positive correlation with the poor therapeutic effect and high KIF18 was associated with lower 3-year overall survival and disease-free survival. The KIF18B-downregulated NCI-N87 cells were constructed and tested by cell counting kit-8 assay and colony formation. Cell migration and invasion were detected by Transwell assay. The xenograft tumor model was established to observe the effect of KIF18B on the efficacy of chemotherapy. The upregulation of KIF18B reduced the chemotherapy sensitivity of GC cells and enhanced their proliferation, migration, and invasion. Silencing KIF18B inhibited tumor growth and promoted chemotherapy efficacy in vivo. In summary, KIF18B inhibitor may have a potential function for improving the efficacy of chemotherapy in GC.
Thermo-mechanical behaviour of a kaolin-based clay soil
Authors: Kirkham Andrew , Tsiampousi Aikaterini , Potts David M.
Published: October 2023

The thermal behaviour of KSS, a low-plasticity artificial clay made with kaolin clay, silt and sand, was investigated in a series of temperature-controlled oedometer tests, at temperatures between 5°C and 70°C, and at vertical pressures up to 2·4 MPa. The experiments investigated the effect of overconsolidation ratio (OCR), pressure level and repeated thermal cycling on thermally induced volume change. Thermal volumetric strains were found to be dependent not only on OCR but also on pressure level, contradicting previous experimental findings and highlighting the importance of even a small dependency of compression index Cc on temperature. Furthermore, thermal volumetric strains were irreversible on heating and cooling even for highly overconsolidated samples. Although irreversibility at high OCR values has been attributed to particle rearrangement and plastic accommodation in the past, an alternative explanation is put forward here, as yielding on the Hvorslev surface is expected to occur on unloading under one-dimensional (1D) conditions. The tests also revealed evidence of thermal creep for the initially normally consolidated samples. The influence of both current temperature and temperature history on the reloading response of mechanically overconsolidated KSS was tested and quantified in terms of their effect on the measured pre-consolidation pressure. The results from these tests were compared to results from the available literature referring to clays of similar and higher plasticity and the comparison highlighted that although soil plasticity can explain the observed quantitative differences between high-plasticity soils to a large extent, mineralogy, in addition to structure, may also play an important role for low-plasticity soils.

Published: October 2023

The study is devoted to identifying the sectoral and geographical structures of foreign trade cooperation between Mongolia and Russia in general and Siberian regions in particular. The paper shows the fundamental role of exports of the mining sector products for the modern economy of Mongolia. The share and place of Russia in the structure of commodity deliveries of Mongolia are indicated. These indicators are also provided in relation to China. The history of foreign economic relations between Russia and Mongolia in recent decades is traced, emerging difficulties have been identified. The role of Siberia in the structure of Russian-Mongolian foreign trade cooperation and the dynamics of its share in recent years are shown. The share and value indicators of trade turnover and the main commodity groups of exports and imports of Mongolia and each Siberian region have been calculated. More detailed attention is given to the regions being leaders in the structure of the Siberian-Mongolian cooperation in terms of both exports and imports. The ways of commodity communication between Mongolia and Siberia are explained. The problem areas of the foreign trade cooperation have been identified: disproportions in the structure of the Siberian-Mongolian trade turnover; one-sidedness of the commodity nomenclature of deliveries from Mongolia; instable prospects for joint trade turnover. The issues of the Mongolian economy’s vulnerability in the context of the country’s current foreign economic model are outlined. Taking into account the geopolitical situation that has changed in 2022, the paper proposes several promising ways of interaction between Mongolia and Russia in general and Siberian regions in particular. Particular attention is on the supply of food products, the expansion of Mongolia’s railway network, the need to increase the processing depth for exported raw materials, the unification of the energy systems of Siberia and Mongolia, the project of the Power of Siberia-2 (Soyuz Vostok) gas pipeline, the creation of an international transport corridor, as well as issues of geological exploration in the territory of Mongolia.

Published: October 2023

The purpose of this study was to estimate the economic impacts of Chinese incentive cruise tourists on three ports of call(Busan, Jeju, and Yeosu) using regional Input-Output (I-O) model. An onsite survey was conducted for 1,000 Chinese incentive cruise tourists to estimate per capita expenditure. Also, tourism sectoral multipliers were derived from the regional I-O tables for three ports of call in terms of output, income, value added, indirect tax, and employment. The survey results indicate that per capita expenditure for Chinese cruise tourists was estimated to be 1.15 million Won and spending on shopping represented the largest amount with 82.7% of per capita expenditure. The results of regional I-O models reveal that Chinese cruise tourism generated 21.7 billion Won of output impact, 5.6 billion Won of income impact, 12.7 billion Won of value-added impact, 0.6 billion Won of tax impact, and 564 jobs of employment impact, respectively. Busan generated the largest economic impact, followed by Jeju and Yeosu(Jeonnam).

Authors:   The Tourism Sciences Society Of Korea, Lee Ki-Seop , Kim Kyung-Sook
Published: October 2023

The hotel industry being highly dependent on human resources, the success or failure of its management is dependent on the competence of each component member of the organization. Therefore, the industry needs outstanding hotel specialists with professional knowledge and site-specific perception. Accordingly, hotel enterprises, realizing the importance of human resources, put a lot of effort into developing personnel to strengthen competitiveness through improvement of productivity and differentiation. The aim of this study was to ascertain the interrelationships between hotel employees’ performance competence while eliciting factors to improve the performance achievement of an organization through the hotel industry’s strategic human resource management. Data were collected from 356 hotel employees in Seoul, S. Korea from September 1 to September 30, 2013. Multiple regression analysis was employed to test the hypotheses. The results showed that hotels’ strategic human resource management has a positive influence on employees’ job competence and on job and organizational performances. We also found that job competence affects job and organizational performances positively. Finally, the results of this study revealed that job performance has a positive effect on organizational performance. Further discussion and implications are provided in the text.

Published: October 2023

Despite of the consistent attention to the relationship among job demands, job resources, and job engagement, the research targeting casual workers and their distinctions depending on gender was scarce in the coffee industry. The purpose of this research was to investigate the relationships among casual workers' job demands, job resources, and job engagement and the moderating role of gender in the coffee industry. The results through structural equation modeling indicated that one of the factors of the job demands (i.e., work overload), and factors of job resources, except for job autonomy (i.e., social support, feedback, and opportunities for self-development), had a significant effect on job engagement. Furthermore, the invariance test showed that gender played a significant moderating role between all factors of job demands and job engagement. However, there was no moderating effect of gender between job resources and job engagement. Implications for academia and management are also discussed.

This study aims to provide appropriate site locations for a medical tourism cluster. The priorities that should be considered in the process of selecting medical tourism cluster include the likelihood of attracting medical service facilities for foreigners, the availability of tourism attractions for foreigners, and the ease of entry such as international airports, ports and etc. However, there is little discussion about which locations are suitable for medical tourism cluster. Thus, this study examines the likelihood of attracting medical facilities and services, the level of specialization in tourism and medical businesses, the accessibility to suburban and urban tourism resources in order to select the right location for medical tourism cluster. The results show that Bucheon and Suwon are the most appropriate locations for medical tourism cluster in Gyeonggi Province. An empirical research approach shown in this study has rarely been used in previous studies particularly within the context of tourism industry. This study has a distinctive feature in that it examines the level of specialization and conditions for such cluster.

Published: October 2023

The study pays attention to the change of business environment that companies should consider social and public value in their operation beyond making profits. It is difficult for small travel agencies to promote the public interest in their operation because they are too small to implement the management strategy of CSR except to make profit. Among structural problems of travel market, the opaque fixed price of travel products discourage consumers from trusting in travel agencies that implement CSR while economies of scale prevent small travel agencies from implementing CSR properly compared to major competitors. Accordingly small travel agencies should build new management strategies, develop new differentiated travel products, establish a network to communicate with distribution channels, segment a market, build a brand strategy. Finally, small travel agencies in Korea need to apply the management strategy of CSR to secure public value demanded by more consumers.

The main characteristic of social commerce is a significantly discounted price for a product or service. This may contribute to the satisfaction of social commerce users, but discriminatory treatment because a customer uses the discount can be a source of dissatisfaction. Perceived risk due to the uncertainty of social commerce may also inhibit satisfaction. The purpose of this study was to identify what influences satisfaction in consumers who purchase restaurant products through social commerce, including consumer innovation, product innovation, perceived risk, and discriminatory experience. A total of 384 respondents who shopped for restaurant deals using social commerce participated through online survey. Chinese tourists who visited Korea participated. Discrimination due to using discounts had the greatest influence on satisfaction among social commerce users. Also, as perceived risk declined, awareness of the innovations in products contributed to higher satisfaction in purchasing restaurant products through social commerce. The managerial implications are discussed.

Authors: Rose Francis L. , Mali Ivana
Published: October 2023

We combined three separate sequential annual data sets (2008–2010) to document general phenology of nesting seasons, reproductive frequency, and interclutch intervals (ICIs) of female Pseudemys texana (Texas River Cooter) and Trachemys scripta (Red-eared Sliders) occupying a spring system in Hays, County, Texas. Detection of gravid females was done through frequent monitoring of nesting areas over three entire nesting seasons. Of the 108 Pseudemys texana that nested in the first year, 54 (50%) also nested in two subsequent years. Of the 65 Trachemys scripta that nested in the first year, only 13 (20%) nested in all three years. Percent of females that nested only in the first year was 10% and 19% for P. texana and T. scripta, respectively. Individuals that nested only once in a season, did so over all days in a season. Multiple clutching within a season was observed for both species. Within year ICIs of females was approximately 30 days for both species and only about 30% of both species nested.

Published: October 2023

Este artículo tiene como objetivo principal identificar cambios en los factores asociados al acceso a la educación superior en una región peruana considerablemente afectada por las desigualdades y por la pandemia del COVID-19, como la Amazonía. Para ello, se planteó un estudio de enfoque metodológico cuantitativo y diseño de investigación no experimental, de tipo transversal. Se compuso una base con datos de 20 097 postulaciones a la Universidad Nacional de la Amazonía Peruana (UNAP), segmentada según las postulaciones se hayan realizado o no durante la pandemia, entre los años 2019 y 2022. Realizamos análisis estadísticos descriptivos y construimos modelos de regresión logística multivariada para estimar el efecto de las variables destacadas por la literatura académica sobre factores que condicionan el ingreso a instituciones universitarias en el Perú. Encontramos que el sexo de los postulantes, el tipo de colegio de procedencia, ser miembro de comunidades indígenas y la modalidad de ingreso son las variables con efectos más fuertes. Además, discutimos la relevancia de los hallazgos para las brechas de género y étnicas que enfrentan los jóvenes.
