Preliminary exploration of tripartite social pain games: Expressions of feelings among three players and game mechanism design
Authors: Weng Yu-pin , Lee I-jui
Published: June 2024

This study aimed to explore the social pain issues that school-age children may encounter when facing social challenges such as misunderstandings, exclusion, and bullying. To simulate social pain scenarios, we designed a three-player game mechanism to assist school-age children in building coping abilities through experiential learning and understanding. In the game design phase, we created game mechanisms involving misunderstandings, exclusion, and bullying, using a three-player ball-passing game to create corresponding situational atmospheres that simulated the experience of social pain. To avoid potential negative impacts on children through direct experimentation, we initially used adults as the experimental subjects. They participated in a three-player social pain game experience to gain preliminary insights into reactions in social pain situations. In the experiment, one participant and two informed players familiar with the game rules engaged in a ball-passing game, completing specific tasks to elicit social pain responses. Assessment tools included a social pain perception questionnaire and stress detection through Garmin wristbands to understand the participants’ physiological responses. Through recording and evaluation, we preliminarily explored the participants’ reactions, experiences, and empathy expressions when facing social pain. The results indicated that these three social pain mechanisms successfully elicited social pain experiences in the three-player game, while also stimulating participants’ empathy. This study provided preliminary research references for future applications of social pain games targeting children.

A system was developed by ISHCCO (International Safety and Health Construction Coordinators Organization) enabling the benchmarking based on technical standards, on international and national criteria. For these reasons the option made was to deduce the quality criteria from the European legislation and from respective national implementations and support these with already established professional and international standards of the European Qualification Framework (EQF). The qualification framework is divided in three criteria for knowledge, skills and attitudes referring to the individual qualifications. In this detailed proposal the existing and accepted criteria from the area of Safety Health Construction Coordinators professionals were examined and compared with the contents of the European Directive 92/57 by institutions, companies, educational and training organizations in Europe and rest of the world. Considering changes brought by UNSDGs to construction sector, ISHCCO prepared a proposal adapting the current IQF (ISHCCO Qualification Framework) to include sustainability concerns about Ethics, Work and Health. Main topics of the proposal addressed mainly the UNSDGs goals 3: Good Health and Well-being, 4: Quality Education, 8: Decent Work and Economic Growth, 9: Industry, Innovation and Infrastructure, 11: Sustainable Cities and Communities, 12: Responsible Consumption and Production, 16: Peace and Justice Strong Institutions and 17: Partnerships to achieve the Goal. The adaptation of competences reflects the needs of SHCC to acquire knowledge, skills and attitudes necessary to have an effective contribution towards the development of the UNSDGs goals. The proposal also includes the recent implications provoked by the publication of the European Union - JRC "Green Comp Sustainability Competence Framework". Proposal includes suggestions on how these adapted competences can be acquired by active SHCC, by other active HS professionals and by future professionals in terms of training and of education.

Published: June 2024

The integration of digital technologies and production elements has profound implications for disturbance and error management in operational-tactical production areas, driven by demands for flexibility, responsiveness, and resilience. Decision support systems (DSS) are seen as crucial tools, leveraging intelligent algorithms to aid decision-making and enhance efficiency.A human-centric DSS, utilizing artificial intelligence (AI) methods, has been developed to facilitate data-driven decisions and shift responsibilities to operational staff. Special attention is given to human-DSS interaction to understand its effects on employee workflows.This work aims to conceptualize a serious game as an innovative method for evaluating the DSS. The game tests technical functionality and simulates impacts on production workflows and human-system interaction (HSI). Realistic scenarios of disturbances, errors, and tool changes will enable early error identification and problem-solving.Through this comprehensive study, improvement opportunities in HSI will be uncovered, and the relevance of the serious game in the DSS context evaluated. AI models will be validated by simulating disruption and error situations in the game, followed by detailed examination of user experience and system value.Multiple participant groups will be involved, with varying levels of DSS assistance, allowing for differentiated analysis of system impacts. This approach will provide a comprehensive understanding of the DSS's practical applicability and benefits in real production environments.

Published: June 2024

Recently intelligent agents have emerged as integral components facilitating the seamless utilization of smart devices in daily life. They serve as instrumental tools for enhancing the precision and efficiency of command execution in human-machine interaction. Despite the prevalence of intelligent agents, their anthropomorphic attributes need a better design to meet user expectations. Thus, investigating the influence of intelligent agent anthropomorphism in terms of user acceptance becomes a necessity.This study designed a mixed-design experiment with anthropomorphic image and role as independent variables and perceived usefulness, perceived ease of use, attitude, intention to use, and trust as dependent variables. The intelligent agent anthropomorphic image had two levels, namely virtual image and simplified image. The intelligent agent designed in this study had three roles, namely steward, assistant, and companion. The task was to plan a travel itinerary with the help of an intelligent agent.The findings reveal that significant differences exist among anthropomorphic images concerning users' perceived usefulness, perceived ease of use, attitude, intention to use, and trust, with users expressing higher acceptance for anthropomorphic agents with simplified images. In the context of travel itinerary planning, no significant differences are observed in all dependent variables regarding anthropomorphic roles. There is no significant interaction effect between intelligent agent anthropomorphic image and role on user acceptance. These findings provide insights for the design of intelligent agent anthropomorphic images and roles.

Published: June 2024

Amidst the pandemic's catalyzation, numerous hospitals rapidly invested in enhancing their mobile service systems. Medical appointment scheduling and outpatient information retrieval are fundamental functionalities of healthcare systems. Poor design in these basic functionalities can lead to negative user experiences, eventually resulting in user abandonment. This study employs a 2 (time selection) x 2 (information layout) factorial experimental design to investigate its impact on user performance, workload, and subjective perceptions. A between-subjects experimental design was utilized, and data were analyzed using a two-way ANOVA. Convenience sampling was used to recruit 32 participants for the experiment. The results revealed that: (1) Calendar date picker widgets are more suited for searching appointments further in the future. (2) Tabular information presentation enhances search efficiency but may require necessary learning and lead to higher cognitive load. (3) In more complex comparative tasks, there could be a transfer of information to the perceptual system, accelerating information absorption and retrieval.

Authors:   Lendi Institute of Engineering and Technology, Vizianagaram
Published: June 2024

Polycystic ovary syndrome (PCOS) is a common endocrine disorder affecting reproductive-aged women, characterized by hormonal imbalance and ovarian cysts. Timely and accurate diagnosis of PCOS is crucial for effective management and prevention of associated complications. In this paper, we propose an automated diagnostic system for PCOS using deep learning and convolutional neural networks (CNNs). The dataset comprises ultrasound images of ovaries categorized into infected (PCOS) and not infected (non-PCOS) classes. Two CNN architectures, a deep CNN model and a CNN model with a last layer replaced by a support vector machine (SVM), are implemented and evaluated. Evaluation metrics include accuracy, precision, recall, and F1-score, demonstrating promising performance in accurately distinguishing between PCOS and non-PCOS cases. This automated diagnostic system offers a reliable and efficient approach for PCOS diagnosis, potentially reducing dependence on manual interpretation of ultrasound scans and improving healthcare outcomes for affected individuals.

Authors:   Electronics and Communication RV college of Engineering
Published: June 2024

Cashew nuts are cultivated widely across the globe and are categorized into various classes according to their size and quality. Currently, cashew kernels are sorted and graded manually, which is time-consuming and labor-intensive. This research proposes hybrid models to automate and accelerate the cashew classification process by integrating classifiers with deep convolutional neural networks (DCNNs). The proposed hybrid models categorize cashew kernels into five groups: W180, W210, W300, W400, and W500. Various hybrid models, including RCNN + OpenCV, were implemented and evaluated based on specificity, accuracy, and other metrics. The results demonstrated that the RCNN model paired with OpenCV achieved a max- imum accuracy of 90%. This study’s findings highlight that automating cashew grading can be significantly enhanced by combining DCNNs with classifiers in hybrid models. These hybrid models improve efficiency by enabling automatic, effective, and precise classification of cashews. By leveraging advanced machine learning techniques, the process becomes faster, more accurate, and less dependent on manual labor. Overall, the integration of deep learning technologies with traditional classifiers offers a promising approach to modernizing and optimizing the cashew grading industry. Future research could further refine these hybrid models to achieve even higher accuracy and efficiency, potentially revolutionizing agricultural sorting processes beyond cashew nuts.

Excessive consumption of sugar-sweetened beverages (SSBs) poses a significant health risk because of their poor nutritional content. This study investigates SSB expenditure among Indonesian households with the goal to analyse disparities and determinants in urban and rural areas. Using the data from March 2022 national socio-economic survey, percentages and means were calculated, and binary probit analysis was performed. The results indicate that the majority of Indonesian households (73.59%) purchase sugary drinks, with slightly higher proportions and mean SSB expenditures observed in rural compared to urban households. Household SSB expenditure at the national level exhibits linear associations with quintiles of household food expenditure and size, a consistent pattern observed in both rural and urban areas. Notably, household composition, including a larger number of children, female adults, and elderly individuals, correlates with reduced SSB expenditures in urban households, while no such trend is observed in rural counterparts. Despite similar access to sugary drinks in rural and urban areas, urgent attention is needed to enhance health literacy among rural households. Interventions through formal education institutions or community-driven initiatives are crucial to address this important health concern and foster healthier beverage choices across the diverse Indonesian landscape.

Published: June 2024

A fitorremediação é uma técnica que utiliza as plantas para aumentar a dispersão ou estabilizar a poluição no meio ambiente. Possui baixo custo, facilidade de implantação e, boa aceitação pública, por não ser invasiva. Assim, o objetivo deste trabalho foi analisar a influência de cromo e 24-epibrassinolídeo (EBL) na emergência e crescimento de Schizolobium parahyba var. amazonicum (Huber ex Ducke) Barneby (Paricá), visando a utilização da espécie como aporte natural ao meio ambiente em detrimento a contaminações por metais pesados nos solos. A pesquisa foi desenvolvida na sala de crescimento de vegetais localizada no laboratório de Estudos da Biodiversidade em Plantas Superiores (EBPS) no Instituto de Ciências Agrárias (ICA), UFRA/Belém. Realizamos contagem dos dias para iniciar a emergência (DIE), e, assim avaliarmos outros parâmetros utilizados para a verificação do crescimento da planta. Dezoito dias após a semeadura as plântulas foram coletadas e submetidas a medições da base da raiz ao ápice para os dados da biometria.  Realizamos também a análise das enzimas antioxidantes, Dismutase do Superóxido (SOD), Peroxidase do Ascorbato (APX) e Atividade de Catalase (CAT) para a verificação de estresse oxidativo sob a influência do cromo. Por meio dos parâmetros de crescimento, constatamos que a aplicação das diferentes dosagens de Cr e EBL não influenciaram na emergência e no crescimento de paricá, como também não interferiram no comprimento da raiz, parte área e no número de folhas do vegetal. O IVE em 11 dias-1 pode ter ajudado a semente a ter menor exposição às condições adversas do meio. Estes resultados podem ser confirmados pela porcentagem de plantas anormais, em torno de 5%, como o Cr é considerado um metal tóxico, poderia ter causado efeitos deletérios as plântulas requerendo a ação atenuadora do EBL. A atividade da APX não ficou evidente, levando o paricá a buscar a ativação do mecanismo compensatório com as duas outras enzimas. A SOD e CAT agiram contra o aumento das concentrações de Cr, quando houve o incremento de EBL nas folhas. O maior aumento de Cr nas folhas de paricá pode caracterizá-la como uma espécie com potencial para fitorremediação.
Chemical semantics: the evolution of meaning of the atom throughout the evolution of chemical science

Published: June 2024

Semantics is the study of meaning. And what does the meaning mean? We will consider the idea that a sign, whether sound or graphic, awakens in people as a good answer. Meaning, like language, is not a static, immutable thing, on the contrary it is constantly evolving. If this does not happen, the meaning ceases to exist and, consequently, the sign as well. A historical example in chemistry is phlogiston, which once proved incapable of opening doors to the future was shelved. The same happened with caloric, murium and others that had meanings not supported by new scientific knowledge. Meaning can change, take new forms, expand the field of meaning to adapt to contemporary knowledge. The atom gives us a magnificent example of meaning in movement capable of adapting to the new achievements of science. The search for understanding matter is undoubtedly a continuous process and one of the most enigmatic in science, an example of this is the evolutionary process suffered by models aiming to describe the atom. There were many philosophers who thought about the constitution of matter, but Leucippus, Democritus, Epicurus and Lucretius were the most visible. Thus, the study of the evolution of the meaning of the atom is the central aspect that will be addressed in this article.

Diferenças cromossômicas foram identificadas em Psidium cattleyanum, com organismos diplóides (2n=22 cromossomos) até citótipos que não são múltiplos do número básico da família (x=11), como 2n=46, 48, 58, 82. Assim, indica que a espécie seja um autopoliploide capaz de aumentar a produção de metabólitos secundários quando comparados as plantas-mãe diploides. Além dos fatores genéticos, os ambientais também podem influenciar no rendimento e composição dos metabólitos secundários, principalmente os óleos essenciais. Diante disso, esse trabalho teve como objetivo investigar a influência da sazonalidade no rendimento e composição química do óleo essencial de P. cattleyanum e avaliar a atividade desses óleos na germinação de sementes, desenvolvimento inicial de plântulas e ciclo celular de meristemas radiculares de Allium cepa. Diferentes concentrações dos óleos essenciais coletados em duas épocas do ano (período chuvoso e período seco) foram aplicadas em ensaios com cebola a fim de verificar a germinação, o índice de velocidade de germinação e o crescimento radicular, que foram afetados negativamente, demonstrando o potencial alelopático desses óleos. O maior rendimento de óleo foi observado nas folhas coletadas no período chuvoso. Observou-se também diferenças na composição química. Além dessas análises a ação citogenotóxica foi avaliada demonstrando atividades significantivas no ciclo celular, com alterações clastogênicas e aneugênicas para ambos os óleos.

Authors: Athinarayanan Kanmani , J Venkatakrishnan C , Philip Jacob Mathew , Ganapathy Aswitha
Published: June 2024

Background: Covid-19 pandemic during 2019 left high mortality rates with mucormycosis (black fungus) as its deadly complication. The spread of black fungus has become global; hence it’s crucial to undertake necessary measures to prevent its spread. Prosthodontists have an inevitable role in the management of mucormycosis and educating the patients regarding the same. The diagnosis of mucormycosis is quite challenging. The treatment should start as quick as possible in order to decrease the death rates. Hence, the knowledge of clinical features and risk factors of mucormycosis is necessary for the prosthodontist in order to provide prompt treatment to the patient.
Materials and methods: A cross-sectional questionnaire based online survey was undertaken amongst 183 Prosthodontists in Tamilnadu and Pondicherry. The questionnaire consisted of 15 questions which evaluated their knowledge, awareness and practice related aspects towards management of postsurgical mucormycosis patients. Statistical analysis was done by using t-test, ANOVA, Pearson and correlation tests. The statistical significance was defined at P < 0.05.
Results: 93% of the study participants were private practitioners in the age group of 25 – 45 years. 106 out of 183 participants had good knowledge about clinical features, prevalent conditions (n=106) and its mode of spread(n=106). They have reported using various prosthesis, grafts and obturators for management of post surgical mucormycosis defects.
Conclusion: Most of the participants were aware about mucormycosis, had reported cases of mucormycosis during Covid-19 and had also employed different methods for prosthetic rehabilitation of patients. However, due to the increase of mucormycosis cases during Covid-19, the practitioners have adopted various methods for rehabilitation.

O estudo buscou investigar as preferências das mulheres em relação à escolha da via de parto, analisando fatores influenciadores, incluindo percepções sobre parto vaginal e cesariana, conhecimento do direito de escolha e impacto de experiências anteriores. Através de um método exploratório e descritivo, com abordagem quantitativa. Foram entrevistadas 560 mulheres. Como ferramenta para a coleta de dados, foi utilizado um questionário estruturado, composto pelos itens estado civil, escolaridade, perfil econômico, além de explorar percepções e influências na escolha da via de parto. Os resultados indicam que a maioria das mulheres expressou preferência pelo parto vaginal (69,8%), sendo tal escolha mais acentuada em determinados grupos demográficos. Apesar disso, a dor do parto foi apontada como um fator relevante nas decisões (55%). Em suma, evidencia-se a preferência pelo parto vaginal entre as participantes, por outro lado, a dor do processo e a falta de informação também se revelaram significativos na escolha da parturiente.

O presente estudo aborda o tratamento da Incontinência Urinária de Esforço feminina visando avaliar taxas de complicações relacionadas à cirurgia de Sling Transobturatório no Serviço de Residência Médica em Ginecologia e Obstetrícia no Complexo Hospitalar do Trabalhador. Foram analisados prontuários de 150 pacientes submetidas à cirurgia de Sling até 2022. Listou-se dados demográficos da população e complicações durante período intra-operatório, internamento, entre internamento e 1º retorno, em 1º e em 2º retornos ambulatoriais. As variáveis analisadas foram: idade, comorbidades, paridade, presença de incontinência urinária mista associada, realização de outro procedimento cirúrgico simultâneo e de fisioterapia pélvica prévia. A média de idade das pacientes foi 54,4 anos. As principais complicações encontradas nas etapas analisadas foram respectivamente: hemorragia (5%), retenção urinária (3%), sangramento (6,4%), vulvovaginite (26%) e manutenção da incontinência aos esforços (26%). A incidência de complicações durante o internamento no grupo com mais de 60 anos foi maior quando comparada às pacientes de até 59 anos (p= 0,024). Nesta mesma etapa, a taxa de complicações em pacientes que realizaram fisioterapia pélvica prévia foi menor em comparação às que não realizaram (p= 0,006). Em 75% das pacientes foi observada ao menos uma complicação em alguma das etapas analisadas. Em conclusão, hemorragia intraoperatória, vulvovaginites, sangramento e retenção urinária estão entre as complicações mais frequentes na população estudada. Os resultados sugerem que a idade avançada e menor taxa de realização de fisioterapia pélvica estão associadas à maior incidência de complicaçaões durante o internamento. Mais estudos são necessários para corroborar com os resultados apresentados.

A anemia é uma condição na qual a concentração de hemoglobina está abaixo do valor considerado normal. No Brasil, existe uma alta prevalência de anemia ferropriva entre os grupos de risco e, portanto, a suplementação profilática está prevista na Atenção Primária do Sistema Único de Saúde. Contudo, a população ainda apresenta muitas dúvidas e crenças culturais relacionadas ao tratamento da anemia que precisam ser esclarecidas. Portanto, realizou-se um estudo descritivo do tipo revisão da literatura no qual foram selecionadas questões recorrentes em serviços de saúde relacionados à anemia ferropriva que nortearam a busca de artigos. Os artigos foram buscados nas bases de dados Google Acadêmico, SCIELO e PUBMED. Verificou-se que a alimentação foi a maior fonte de questões que resultam em mitos e verdades e demostrou-se sua relevância no contexto da anemia. O conhecimento e esclarecimento de dúvidas como as trazidas por esse trabalho por parte dos profissionais de saúde para a população do seu território, junto com o incentivo a profilaxia e tratamento, pode auxiliar no controle desse agravo tão prevalente.

Prediction of Crystal Size and Microstrain Using Artificial Neural Network From Gaussian Peak Shape Analysis of X-Ray Diffraction Data
Authors: Sang Nguyen Duy , Quoc Thi Ha Hoang
Published: June 2024

X-ray diffraction (XRD) is a widely used technique in materials science to determine crystal structure, crystal size and peak shape of crystalline materials. However, the interpretation of XRD data is often challenging due to the complexity of the diffraction patterns and the presence of noise. In this study, we demonstrate the application of artificial neural networks (ANNs) to predict crystal size and peak shape from XRD data using the Gaussian function. ANNs are a powerful machine learning tool that can learn complex relationships between input and output variables. Our results suggest that ANNs can be a valuable tool for the interpretation of XRD data, especially when the diffraction patterns are complex or noisy. The average value of the crystal size is estimated and evaluated by the figure of merit parameter. This approach has potential applications in materials science, where accurate characterization of crystal structure and size is essential for understanding material properties and designing new materials.
