Coupled 3D peridynamics and refined 2D finite elements models embedded in a global\local approach
Authors: Enea M.
Published: August 2023

Abstract. The present work proposes a two-step global\local approach for the three-dimensional analysis of structures . In particular, the first step makes use of classical finite element modelling, based on classical 2D elements, whereas a refined higher-order model based on the Carrera Unified Formulation (CUF) is coupled with a 3D peridynamics domain for the local analysis. The solution from the proposed method is compared with a full FEM solution. The objective of the present work is to pave the way to the building of a framework where coupled FE\PD models are embedded into this global\local approach to solve progressive failure problems.

Authors: Gori O.
Published: August 2023

Abstract. This paper reports the work performed in the field of the H2020 MORE&LESS Project to contribute to shaping global environmental regulations for supersonic aviation. The existing CO2 emission standard, which is defined for subsonic aircraft, is analyzed. However, the applicability of this standard to supersonic concepts needs to be assessed. A case study of a Mach 2 concept, based on the Concorde configuration, is considered to explore modifications needed for the CO2 metric value calculation. The results provide insights into the CO2 metric value for a supersonic aircraft and its comparison with subsonic aircraft limits.
High-fidelity simulation of shock-wave/boundary layer interactions
Authors: Ceci A.
Published: August 2023

Abstract. We perform direct numerical simulations of impinging shock-boundary layer interaction on a flat plate, in which the shock is not orthogonal to the boundary layer flow. The analysis relies on an idealized configuration, where a spanwise flow component is used to introduce the effect of the sweep angle between a statistically two-dimensional boundary layer and the shock. A quantitative comparison is carried out between the swept case and the corresponding unswept one, and the effect of the domain spanwise width is examined. The analysis reveals that, while the time-averaged swept flow characteristics are basically unaffected by the choice of the domain width, the spectral dynamics of the flow dramatically changes with it. For very narrow domains, a pure two-dimensional, low-frequency component can be detected, which resembles the low-frequency oscillation of the unswept case. The present work is also devoted to compare the performance of Digital Filtering (DF) and Recycling-Rescaling methods (RR) in reaching an equilibrium state for the Direct Numerical Simulation (DNS) of a turbulent boundary layer. We performed two sets of DNS of supersonic and hypersonic boundary layers, based on previous numerical studies. It is found that, overall, the RR method is the most appropriate choice, to quickly reach a correct trend of the wall pressure fluctuations, whereas the DF method is more capable in obtain small deviations of the skin friction coefficient with respect to the benchmark.

Published: August 2023

Abstract. Quality and safety of products and services are very important factors influencing customers' decisions about the purchase. They affect the level of customer satisfaction, but also their safety during consumption. A great deal of information about customers' perceptions of products can be inferred from the complaints they file. Complaint indicators can easily be used to analyze the quality of services available on the market. The purpose of the research was to analyze complaints filed by customers of a chosen e-shop from Poland. The analysis was based on data from January 2017 to December 2021. An analysis was made of the number of complaints filed in relation to the number of orders placed. The percentage of complaints recognized by the manufacturer and the reasons for filing complaints were presented. This analysis should be a starting point for the researched e-shop for improvement measures to raise the level of customer satisfaction.
Measurements of Vehicle Azimuth Using Acoustic Signals
Authors: MADEJ W.
Published: August 2023

Abstract. The location of objects based on the analysis of acoustic signals is widely used in various civil and military systems. Applications that allow the users to determine the location of the sound source are used, for example, in conference rooms for automatic speaker location, enabling unattended camera control, detecting and tracking the movement of objects in area surveillance systems, etc. The paper presents a system for determining the azimuth of a moving motor vehicle developed at the Military Institute of Engineer Technology in cooperation with the Wroclaw University of Technology. The system is designed for the detection, identification and location of armored vehicles and trucks. The use of acoustic signal analysis methods to locate objects allowed for the construction of passive systems that are difficult to detect. This property is particularly important in area surveillance systems and military equipment designs.

The Vinyasa Tool for mHealth Solutions: Supporting Human-Centered Design in Nascent Digital Health Ecosystems
Authors: Thomas Verghese , Kalidindi Bharat , Waghmare Abijeet , Bhatia Abhishek , Raj Tony , Balsari Satchit
Published: August 2023

Background

mHealth (mobile health) systems have been deployed widely in low- and middle-income countries (LMICs) for health system strengthening, requiring considerable resource allocation. However, most solutions have not achieved scale or sustainability. Poor usability and failure to address perceived needs are among the principal reasons mHealth systems fail to achieve acceptance and adoption by health care workers. A human-centered design approach to improving mHealth system use requires an exploration of users’ perceptions of mHealth systems, including the environmental, user-related, and technological aspects of a system. At present, there is a dearth of contextually intelligent tools available to mHealth developers that can guide such exploration before full-scale development and deployment.

Objective

To develop a tool to aid optimization of mHealth solutions in LMICs to facilitate human-centered design and, consequently, successful adoption.

Methods

We collated findings and themes from key qualitative studies on mHealth deployment in LMICs. We then used the Informatics Stack framework by Lehmann to label, sort, and collate findings and themes into a list of questions that explore the environment, users, artifacts, information governance, and interoperability of mHealth systems deployed in LMICs.

Results

We developed the Vinyasa Tool to aid qualitative research about the need and usability of mHealth solutions in LMICs. The tool is a guide for focus group discussions and key informant interviews with community-based health care workers and primary care medical personnel who use or are expected to use proposed mHealth solutions. The tool consists of 71 questions organized in 11 sections that unpack and explore multiple aspects of mHealth systems from the perspectives of their users. These include the wider world and organization in which an mHealth solution is deployed; the roles, functions, workflow, and adoption behavior of a system’s users; the security, privacy, and interoperability afforded by a system; and the artifacts of an information system—the data, information, knowledge, algorithms, and technology that constitute the system. The tool can be deployed in whole or in part, depending on the context of the study.

Conclusions

The Vinyasa Tool is the first such comprehensive qualitative research instrument incorporating questions contextualized to the LMIC setting. We expect it to find wide application among mHealth developers, health system administrators, and researchers developing and deploying mHealth tools for use by patients, providers, and administrators. The tool is expected to guide users toward human-centered design with the goal of improving relevance, usability, and, therefore, adoption.
Strengthening Cybersecurity for Patient Data Protection in Europe (Preprint)
Authors: van Kessel Robin , Haig Madeleine , Mossialos Elias
Published: August 2023

UNSTRUCTURED

The health care sector experiences 76% of cybersecurity breaches due to basic web application attacks, miscellaneous errors, and system intrusions, resulting in compromised health data or disrupted health services. The European Commission proposed the European Health Data Space (EHDS) in 2022 to enhance care delivery and improve patients’ lives by offering all European Union (EU) citizens control over their personal health data in a private and secure environment. The EU has taken an important step in homogenizing the health data environment of the European health ecosystem, although more attention needs to be paid to keeping the health data of EU citizens safe and secure within the EHDS. The pooling of health data across countries can have tremendous benefits, but it may also become a target for cybercriminals or state-sponsored hackers. State-of-the-art security measures are essential, and the current EHDS proposal lacks sufficient measures to warrant a cybersecure and resilient environment.

Published: August 2023

BACKGROUND

Distress is highly prevalent among patients with cancer, but supportive care needs often go unmet. Digital therapeutics hold the potential to overcome barriers in cancer care and improve health outcomes.

OBJECTIVE

This study conducted a randomized controlled trial to investigate the efficacy of Mika, an app-based digital therapeutic designed to reduce distress across the cancer trajectory.

METHODS

This nationwide waitlist randomized controlled trial in Germany enrolled patients with cancer across all tumor entities diagnosed within the last 5 years. Participants were randomized into the intervention (Mika plus usual care) and control (usual care alone) groups. The participants completed web-based assessments at baseline and at 2, 6, and 12 weeks. The primary outcome was the change in distress from baseline to week 12, as measured by the National Comprehensive Cancer Network Distress Thermometer. Secondary outcomes included depression, anxiety (Hospital Anxiety and Depression Scale), fatigue (Functional Assessment of Chronic Illness Therapy-Fatigue), and quality of life (Clinical Global Impression-Improvement Scale). Intention-to-treat and per-protocol analyses were performed. Analyses of covariance were used to test for outcome changes over time between the groups, controlling for baseline.

RESULTS

A total of 218 patients (intervention: n=99 and control: n=119) were included in the intention-to-treat analysis. Compared with the control group, the intervention group reported greater reductions in distress (P=.03; ηp²=0.02), depression (P<.001; ηp²=0.07), anxiety (P=.03; ηp²=0.02), and fatigue (P=.04; ηp²=0.02). Per-protocol analyses revealed more pronounced treatment effects, with the exception of fatigue. No group difference was found for quality of life.

CONCLUSIONS

Mika effectively diminished distress in patients with cancer. As a digital therapeutic solution, Mika offers accessible, tailored psychosocial and self-management support to address the unmet needs in cancer care.

Published: August 2023

The objective of this study was to evaluate fresh and frozen storage of lamb longissimus lumborum (LL) and semimembranosus (SM). Wether lambs (n=12) were raised and harvested at North Dakota State University. After a 24-h chill, loins and legs were split in half and randomly assigned to fresh (FRSH) or frozen (FRZN) treatments. FRSH halves were stored at 3°C for 14 d while FRZN halves were stored at −18°C for 13 d+1 d to thaw at 3°C. Samples were collected to evaluate sensory attributes, Warner-Bratzler shear force, cook loss, drip loss, troponin-T (TnT) degradation, and lipid oxidation. Data were analyzed using PROC MIXED of SAS Studio®. Experimental units were loin or leg with means being separated with the PDIFF option and were considered significant when P<0.05. In FRSH-LL, sensory samples scored higher in overall like, tenderness, and juiciness (P≤0.03) compared with FRZN-LL samples. No differences in overall like,flavor, tenderness, or juiciness scores (P≥0.77) were observed between FRSH-SM and FRZN-SM. FRSH-LL and FRSH-SM had less drip loss compared with FRZN-LL and FRZN-SM (P<0.0001, P=0.0003, respectively). FRSH lamb LL and SM had greater degradation of TnT (P≤0.0008) compared with FRZN lamb. Malondialdehyde levels were not different (P>0.05) between treatments within each muscle. However, no other meat quality differences were observed (P≥0.10). Our results demonstrate that lamb legs may be frozen for 13 d without negative effects on palatability whereas lamb loins should be kept fresh to offer the greatest opportunity for consumer satisfaction.

Published: August 2023

Objectives The purpose of this study was to classify latent groups of self-understanding among college students who participated in a PBL class using latent profile analysis (LPA) and to explore the factors that affect this classification.
Methods To achieve these objectives, we collected samples from the ‘5th year KEEP II: Korea Education & Employment Panel II’. The variables selected to investigate the factors influencing the classification were ‘PBL class satisfaction’, ‘major satisfaction’, ‘campus life satisfaction’, and ‘life satisfaction and freedom’.
Results The results of this study are as follows: First, self-understanding types were classified into three categories: ‘low level’, ‘middle level’, and ‘high level’. Second, significant differences were found in ‘PBL class satisfaction’, ‘major satisfaction’, ‘campus life satisfaction’, and ‘life satisfaction and freedom’. The ‘high level’ group showed the highest levels in all factors. The ‘middle level’ group demonstrated overall levels above average but relatively lower levels of ‘goal execution’. Finally, the ‘low level’ group exhibited low levels in all measured variables, particularly in factors related to decision-making.
Conclusions This study is significant in that it examines the characteristics of learners with high and low levels of self-understanding, specifically focusing on those who experienced a specific class type, PBL. Therefore, we suggest that instructors should identify and implement teaching strategies and learning activities that promote self-understanding and enhance the effectiveness of PBL.

Methods To this end, data were collected through group focus group interviews, class observations, and teachers' council visits with 16 IB MYP candidate schools and world school teachers (as of ΄21) in A region that are introducing the IB program in public education. Analyzed and organized.
Results As a result, teachers' curriculum literacy improved in the process of understanding the national curriculum for the application of the IB program, and professionalism, autonomy, and responsibility increased in the composition of classes and assessments. Although the IB evaluation system was cited as the biggest factor in improving class instruction, under the current situation, they felt the burden of operating dual evaluation systems such as nice evaluation and summative evaluation, relative evaluation and absolute evaluation, and short answer and multiple choice evaluation. Most of the teachers said that systematic IB education contributes greatly to the development of teacher professionalism and the strengthening of students' competence, but it is very important to secure the research time necessary for teachers' class design and preparation. Teachers said that the ‘evaluation system’, ‘school quality management system’, and ‘structure that induces collaboration’ were attractive in IB education, while lack of research time, sense of responsibility and pressure for IB program application classes and evaluation, and individual feedback The large number of students managed and the burden as a leading teacher appeared as job stress. Teachers thought that the IB program was a very good educational device, but it should be accompanied by training support, work reduction, and changes in the form of entrance exams to secure teacher expertise.
Conclusions Therefore, in this study, in order for IB education to stably settle in public education, the feasibility of introducing IB education and the formation of strong consensus among members on the educational effects, securing teacher research time, supporting IB teacher network establishment, and developing IB school teachers and student growth. Necessities such as development of measuring tools, improvement of teacher training system, accumulation of data on introductory evaluation method, and exploration of the IB program applied curriculum education implementation process were suggested.

Published: August 2023

Objectives The purpose of this study is to look at the current status and problems of out-of-school youth, analyze the life situation of out-of-school youth and difficulties in choosing a career, and devise a plan that can be of practical help to them.
Methods As for the research method, various literature, research papers, and government policy-related data were collected and reviewed in order to examine the current status and problems of academic suspension of out-of-school youth, and in-depth interviews with research participants were conducted to determine the actual state of life after school suspension and actual career path. The contents of the selection method were analyzed in depth.
Results The results of this study showed that the common psychological characteristics of adolescents who dropped out of school were that they had no clear goals and hopes due to helplessness at the time of dropping out of school, and they had no specific plans for what they would do or want to become after dropping out of school. As a result of the interview with the research participants, the representative factor of school dropout was a combination of academic factors and family factors. As for the family factors, economic difficulties due to parental divorce and lack of care in the family were found to be the causes. Complex factors include cases in which several factors, such as academic problems, friends problems, and family problems, work in combination.
Conclusions In conclusion, it seems that out-of-school youth's life situation and career choice should first come up with a plan to resolve the sense of dropout and alienation of youth who cannot adapt to the institutional framework of public education. Second, there is a need for management and support measures for adolescents who are maladjusted to school, starting from family dissolution due to parental divorce and economic conditions. Third, legal and institutional management and support are needed for adolescents with poor academic performance or difficulties in adapting to school life. Fourth, counseling and support for the mental health and welfare of adolescents should be activated. Finally, it is necessary to expand institutional and policy support for out-of-school youth.

Objectives This study seeks to explore what kind of changes the experience of career activities through participation in the career exploration credit system makes university students experience changes in their perspectives and perceptions.
Methods To this end, five university students who participated in the career exploration credit system activities implemented by K University were asked, ‘What kind of experience did participating in the career exploration credit system have?’ and ‘What is the meaning of the experience of participating in the career exploration credit system?’ It was conducted as a case study.
Results As a result of the study, core components such as ‘positive change in perspective and perception through the experience of designing and executing career activities by oneself’ and ‘improvement of self-confidence through voluntary participation experience’ were derived.
Conclusions The implications obtained through this study are as follows. First, it is necessary to provide college students with experiences of self-directed class design and practice. Second, it is necessary to expand career subjects that college students can be interested in through self-directed activity experiences. Third, it is necessary to prepare an institutional device for university students to experience a lot of application of the process of planning, designing, and executing themselves. In conclusion, it is expected that a new career-related model, such as the career exploration credit system, will be continuously developed and implemented for college students who are struggling between career and employment, so that they can design and realize practical field-oriented activity experiences or projects unrelated to their major.
Da normalização à ecologia dos saberes: de que saúde estamos falando?

O presente estudo tem como centralidade o conceito de saúde e o modo como está a ser concebido na sociedade atual. A discussão acerca do conceito de saúde é complexa, visto que percebemos uma dificuldade em abordá-la devido a sua polissemia. Sendo assim, saúde poderia se caracterizar como a possibilidade de agir e reagir, de adoecer e se recuperar. Desse modo, o trabalho objetiva discutir a noção de saúde a partir da ótica normalizadora, propondo as ecologias do saberes como possibilidade de operar com outras maneira de promover a saúde. O escopo metodológico desenvolveu-se por intermédio da revisão narrativa, problematizando a saúde enredada ao conceito de normalização articulada ao debate promovido pela epistemologias do Sul. No intuito de problematizar a concepção de saúde utilizamos as discussões de Canguilhem (1995; 2009), Foucault (2008) Palma (2010; 2012), Santos (2013; 2018), dentre outros.

A utilização de plantas medicinais para fins terapêuticos é uma prática milenar usada por várias pessoas ao redor do mundo. Entretanto, os saberes e a eficácia desses recursos genéticos vegetais ainda são pouco discutidos em sala de aula, principalmente na perspectiva de valorização dos conhecimentos etnobotânicos. O estudo buscou identificar a utilização das plantas medicinais para fins terapêuticos por alunos em uma escola pública do Piauí, assim como, verificar as contribuições desses saberes para o ensino de Botânica no Ensino Médio. A pesquisa empregada foi exploratória, com abordagem qualitativa e quantitativa. Quarenta e sete alunos do Ensino Médio participaram do estudo. A coleta de dados foi realizada pelo formulário eletrônico, vinculado a plataforma do Google (Google Forms). Os dados quantitativos foram analisados pelo teste Mann-Whitney e Test-t (p<0,05). Os alunos desta escola utilizavam as plantas medicinais para fins terapêuticos (74,5%). As estruturas das plantas mais empregadas foram as folhas e casca. O chá foi reportado como a forma de preparo mais citada. No entanto, os alunos não tinham conhecimentos sobre os problemas que possíveis princípios ativos presentes nesses vegetais poderiam ocasionar ao material genético humano. O estudo etnobotânico não foi identificado através do ensino de Botânica nesta escola. Portanto, há necessidade de integrar esses saberes, de modo a despertar o interesse dos alunos em preservar essas espécies medicinais e fortalecer o conhecimento tradicional associado.

Este trabalho teve por objetivo identificar os conhecimentos prévios dos ingressantes de um curso de Engenharia de uma Universidade Pública do interior do Paraná, provenientes de diversos Estados do País. A partir de tais dados buscou-se trabalhar lacunas de formação. Para tanto, foi utilizada atividades mediadas para despertar a criatividade e a autonomia dos acadêmicos na resolução de questões de medições durante a disciplina de Física 1, com o intuito de potencializar o processo de ensino-aprendizagem deste conteúdo, uma vez que este seja pré-requisito para a compreensão dos demais conteúdos programáticos. Foram utilizadas Tecnologias Digitais de Informação e Comunicação (TDIC) através de Aplicativos e Softwares, Ambiente Virtual de Aprendizagem (AVA) e experimentos no laboratório de Física. Tais ações compuseram uma Sequência Didática (SD), por meio da qual os dados foram coletados. Nesse processo foi utilizado para a análise relatórios, questionários e diário de bordo do professor. Com os dados analisados, foi possível verificar que os acadêmicos apresentavam dificuldades em relacionar a Física com o cotidiano, de modo a não identificarem viverem em um mundo metrificado; que apresentavam muita habilidade na manipulação dos aplicativos os quais puderam conhecer durante a SD; que possuíam pouca informação quanto às possibilidades de ensino que podem ser realizadas com o Smartphone. Os resultados apontam ainda sobre a importância de uma abordagem teórica e experimental deste conteúdo no ensino médio. Assim, a SD pode resgatar os conceitos sobre medição de forma materializada e lúdica colaborando com o processo de ensino-aprendizagem, bem como explorar com os discentes alguns aplicativos úteis no curso de Engenharia Civil.
Ética Ubuntu nas discussões sobre experimentação científica: colonialidade e (des)humanização no ensino de Química

Este artigo se configura em um ensaio teórico que tem como intuito evidenciar as possibilidades de discussões éticas a partir da experimentação no Ensino de Química. Por meio de uma ampla revisão de literatura, abordamos alguns aspectos históricos acerca da experimentação no Ensino de Química, em articulação com o conceito de cidadania, destacando que não formamos para a cidadania se deixamos de lado discussões que estão no campo da interculturalidade. Pautamos a necessidade do debate sobre a decolonialidade e a ética Ubuntu na produção do conhecimento científico-experimental a partir do caso referente ao uso de mulheres haitianas e porto-riquenhas como cobaias para testes com as pílulas anticoncepcionais na década de 1960, visando problematizar as motivações colonialistas por trás destas práticas empíricas.
