Ergonomic Risk Factors of Musculoskeletal Injuries in Aviation Maintenance
Authors: Aljaroudi Ali
Published: June 2024

The aviation maintenance mechanic faces a multitude of occupational hazards each day due to the complex nature of the work they perform on aircrafts. The most common problem reported by aviation maintenance mechanics was work related musculoskeletal disorders (WMSDs). Studies have shown that aviation maintenance mechanics suffer WMSDs, most often affecting the back, head, neck and lower extremities. The objective of this study is to assess the risk of WMSDs and propose innovative engineering control of ergonomic hazards associated with aviation maintenance work in a local aviation maintenance hanger. The ergonomic assessment tool used was the Rapid Entire Body Assessment (REBA). This ergonomic assessment tool uses a systematic process to evaluate whole body postural and risks associated with job tasks. Using the REBA worksheet, the evaluator assigns a score for each of the following body regions: wrists, forearms, elbows, shoulders, neck, trunk, back, legs, and knees. The scores for each of these body parts vary. The lower arm score can either be valued as a 1 or 2. The neck and wrist REBA score can range from 1 to 3. The legs are scored 1 to 4. The trunk is on a scale of 1 to 5 with the upper arm stretching as high as a score of 6. Although these scores have different boundaries, the lower they are, the better. Scoring a 1 in all these categories would ensure the workplace is ergonomically friendly and free of wide exposure to WMSDs. The assessment body region score was complied with the risk factor variables, (force/load score, coupling score and activity score) generating a single score that represents the risk level of WMSDs. This individual number tells the evaluator how urgent change is needed. After observing the aviation maintenance mechanics repairing an aircraft engine, an ergonomic risk assessment of the mechanic was conducted using the REBA tool. The final ergonomic assessment resulted in an average REBA score of 9, which represents the risk level of WMSDs. This score indicates that aviation mechanics are at a high risk of WMSDs. Interventions are recommended to reduce the risk of harm to aviation maintenance mechanics. Our study results show that aviation mechanics working at the assessed maintenance hanger are at high risk of WMSDs due to improper engineering controls. The aviation mechanics are subjected to musculoskeletal pain while working in awkward positions and repetitively repeating tasks with no ergonomic benefits. Implementing the recommended engineering controls that re-engineer work practices, processes, posture and body movement will reduce the potential risk of WMSDs. Utilizing ergo chairs, anti-fatigue mats, and ergonomically designed tools will improve the REBA score, resulting in low risk. The common theme of poor posture and lack of ergonomic friendly tasks throughout the worksite will be reduced to an acceptable level through ergonomic interventions.

Published: June 2024

The construction industry is a motive force, and a good proxy to measure a significant level of development in an economy. Supply chain management (SCM) is a significant aspect in the industry to help synergize collaboration between construction stakeholders to improve the performance in the construction sector. This study assessed the barriers facing SCM integration in the South African construction industry (SACI). The study adopted a quantitative research method with data gathered from the participants with the SACI. The information obtained was analyzed using mean item score, standard deviation, and Cronbach alpha. The findings showed that lack of integration in the SACI is influenced by factors such as lack of investments in the supply chain management sector, lack of collaboration among constriction professionals, skills shortages in the construction sector, inefficiencies and delays in construction project delivery, limited use of technology in monitoring project progress, a lack of innovation and investment in the construction sector. These were seen as the barriers facing the adoption of SCM in the SACI. The lack of adopting SCM in the SACI can lead to an enormous decline in the construction industry and economic infractions. Therefore, it requires an effective central government clear roadmap and industry stakeholders’ participation to help stifle the bottleneck currently maligning SCM integration in the SACI. This can be achieved through a national SCM strategy, that promotes SCM awareness and knowledge, by fostering a collaborative and innovative culture and providing financial and technical assistance to this course. The study of SCM will improve efficiency and effectiveness in the construction industry by promoting collaboration between construction stakeholders, greatly improving construction completion time, increasing customer satisfaction and confidence, and most importantly improving the political and economic situation in the region.

Authors: Marie Memmesheimer Vera , Thomas Chuang Ian , Ravani Bahram , Ebert Achim
Published: June 2024

Robotic systems for several applications from healthcare to space explorations are being developed to handle different levels of autonomy – from working independently to working in collaboration with or under control by human operators. To ensure optimal human-robot cooperation, appropriate UIs are needed. In this context, applying Mixed Reality handheld displays (MR-HHDs), an ubiquitous tool for virtually augmenting reality, seems promising. As existing MR-HHD-UIs for robot control employ fatigue-prone and view-obstructing touch input, we propose controlling a robot arm via an enhanced MR-HHD-UI based on peripheral touch and device movement. Our detailed, comparative user study on usability and cognitive load demonstrates that the proposed MR-HHD-UI is a powerful tool for complementing the strengths of robots and humans. In our experiment, the MR-HHD-UI outperformed a Gamepad- and Desktop-UI in terms of temporal and cognitive demands and was rated as the preferred UI.

Published: June 2024

Children with autism spectrum disorder often struggle with emotional communication due to innate emotional disorders. They find it difficult to express their own emotions and also struggle to understand the emotional states of others. These innate emotional barriers force them to rote memorize or mechanically learn specific emotional expressions, hindering effective emotional communication and expression.However, the abstract nature of emotional communication issues makes it challenging for autistic children to effectively express their feelings, leading to negative behaviors such as violence or self-harm due to emotional repression.To address this, we aimed to develop emotive toys, incorporating metacognitive game mechanics, to serve as tools for emotional communication and training for children with autism. For this purpose, we recruited several designers to collaboratively develop these emotive toys through workshops. Empathy mapping was used in these workshops to help the designers understand the emotional communication challenges faced by children with autism and inspire the design of emotive toys.After discussions, the designers proposed three different concepts for emotive toys, from which one was selected for further experimental validation. This selected toy was provided to eight pairs of players for an emotional communication game. The players used the toy's operations and sensory stimuli to communicate and express emotions.The results showed that through this game mechanism, all eight pairs of participants were indeed able to effectively communicate and express emotions, demonstrating that the toy effectively conveyed emotional information.

Published: June 2024

With the popularity of online general education in China, there appeared a common concern that students may not be motivated enough to self-regulate when learning general education courses online, which may cause unsatisfactory learning outcomes. To better understand how students self-regulated learning (SRL) in general education courses when adapting to an online learning environment, we conducted a two-stage survey (N = 163) on students in general education courses in social science discipline. Three typical SRL profiles were identified: (1) The high SRL profile who were highly self-regulated; (2) The low effort profile who were overall highly self-regulated but use less Peer Learning and put low effort into learning; and (3) The low SRL profile who were overall less self-regulated. The former two profiles had significantly higher perceived gain and satisfaction than the latter. Value and expectancy components of motivation, self-discipline, platform functions and supplementary reading facilitated overall use of SRL strategies, while test anxiety reduced students’ use of Peer Learning and Effort Regulation. These findings revealed the current status and possible causes of Chinese students' SRL in online general education courses, and provided implications for improving online general education.

Published: June 2024

Low student academic performance is a problem that has been addressed in recent decades. It is expected that these learning problems will be addressed through teaching practices, improving their methodological processes in response to diversity in the classroom. Learning styles are an orientation that allows us to understand this diversity and improve methodological proposals. The objective of this research is to describe the effect generated by various learning styles on the academic performance of middle-level basic general education students in the 2022-2023 school year. For this, a mixed approach research is proposed, with a descriptive scope and field research through the use of the VARK test for learning styles, a grade record to determine academic performance and an observation sheet for teachers. A student population of 88 students and observation of 3 teachers from the institution were considered. The results of the research show that teachers do not tend to generate novel methodological practices, while in learning styles, a prevalence was found in the kinesthetic and visual style, the latter having a correlation with academic performance.
Design Feeling: a symmathetic approach for design processes
Authors: Simas Da Silva Gustavo , Ribas Ulbricht Vânia
Published: June 2024

Exploring the evolution of design from creating tangible products to orchestrating intangible experiences and socio-technical systems, we introduce "Design Feeling" (DF) as a novel approach for design processes, transcending the problem-solving goal by integrating emotional resonance, intuition and symmathesy. While Design Thinking has historically emphasized a problem-solution approach focusing on user-centered problem-solving, DF advocates for a systems feeling that addresses complex, interconnected challenges through participatory design, empathy, intentionality and political engagement. This shift requires a new kind of designer, one who acts as a facilitator of community interaction and a steward of ecological health, aiming to create solutions that are both resonant with users and responsible to the broader ecosystem, being a “cautious Prometheus” as well. We highlight the need for a critical reevaluation of design practices to ensure they contribute to sustainable and equitable progress, proposing a movement towards a design philosophy that harmonizes technical skills with emotional and relational understanding.

Authors: Mohammed Shajeer , Ramadas Sathyanarayana
Published: June 2024

In today's rapidly evolving digital landscape, businesses rely heavily on efficient and reliable hardware and software solutions to maintain competitiveness and meet the demands of an increasingly connected world. Hyper-Converged Infrastructure (HCI) has evolved as a cornerstone in modern data center architecture, offering an integrated solution for compute, storage, and networking. The deployment of a highly available hyper converged appliance for containerized platforms presents unique challenges and opportunities from a human factors’ perspective. As customers embrace containerization for deploying and managing applications, it is essential to consider the human element in the design and implementation of such appliances. Designing an HCI (Hyper-Converged Infrastructure) appliance following a traditional approach is a meticulous process that often spans several months and requires the expertise of various professionals. From conceptualization to procurement to assembly and putting to production each step demands careful consideration to ensure seamless integration of hardware and software components ranging from ordering a complex mix of servers, switches, racks, PDU’s and then finding a set of software that can be installed on this infrastructure for day-to-day use and management.Once the design is finalized, acquiring the necessary equipment involves navigating complex supply chains and negotiating with multiple vendors. Manual configuration tasks such as initializing servers, setting up network connections, and configuring storage arrays demand painstaking attention to detail. Additionally, implementing monitoring appliances to ensure performance and reliability further extends the deployment timeline. Scaling the infrastructure by adding additional servers and disks introduces another layer of complexity, requiring careful planning and execution to maintain appliance integrity and performance.This paper investigates the implementation and integration considerations of Human factors concepts across various stages in commissioning an HCI appliance along with its operating and management software in a data center. We discuss how the design helps to improve usability, efficiency, productivity, error prevention, and adaptability in the installation, configuration, and operation processes. We also explore how managing a highly available hyper converged appliance that is pre-built from factory is recommended in comparison to building your own appliance how the overall design of hardware and software optimizes the user experience of getting a complex appliance into production use swiftly.

Published: June 2024

In order to help automotive interior and exterior decoration and human-computer interaction interface designers effectively avoid the risk of poor interface usability and further enhance the user experience, we quantify the complexity of human-computer interaction behaviors in smart cars, and explore the specific task indicators and weight distributions affecting the complexity of human-computer interaction inside the smart cockpit, as well as propose a methodology for measuring the complexity of human-computer interaction tasks in smart cars. First of all, by adopting the method of questionnaire survey, an index system consisting of eight evaluation indexes, namely, the complexity of logical structure, the complexity of interface design elements, the complexity of information channel transmission method, the number of actions, the complexity of management interface information, the complexity of human-computer interaction inputs, the level of knowledge and cognitive volume required for human-computer interaction, and the complexity of the layout of human-computer interaction digital interfaces, has been established. Secondly, we use the weight calculation method that combines Fuzzy Analytic Hierarchy Process (FAHP) and Entropy Weight Method（EWM) to determine the factors that have the most influence on the complexity of human-computer interaction behaviors of the smart cockpit. Finally, human-computer interaction behaviors with high complexity are calculated and design optimization recommendations are made. The evaluation results show that the complexity of the human-computer interaction digital interface layout in the cockpit (X8), the complexity of the logical structure (X1), and the level of knowledge and cognition required for human-computer interaction (X7) have a greater impact on the complexity of human-computer interaction tasks in the vehicle. Meanwhile, navigation operation, video and audio playback and music selection switching are human-computer interaction tasks with higher complexity and also need to be explored by designers focusing on them. The method can help designers avoid the risk of excessive design complexity and high user learning costs, and can assist designers to intervene in advance of design problems related to the above indicators.

Authors:   Information Science and Engineering, RV College of Engineering, Bangalore, India, Kamarthi Aditya
Published: June 2024

In today’s data-driven landscape, the reliability and accuracy of information are paramount for informed decision-making and operational efficiency. A robust data quality framework provides a structured methodology for managing and maintaining the quality of data as-sets throughout their lifecycle. It in-troduces a comprehensive data qual-ity framework encompassing four key pillars: data governance, data profil-ing, data cleansing, and data monitor-ing. The foundation of the framework lies in establishing clear data governance policies and procedures, defining owner-ship, responsibilities, and accountability for data quality across the organization. Data profiling techniques are then em-ployed to assess the quality of data, iden-tifying anomalies, inconsistencies, and inaccuracies. Subsequently, data cleans-ing processes are implemented to rec-tify these issues, employing techniques such as deduplication, standardization, and validation to ensure data integrity. Continuous data monitoring is integral to the framework, enabling proactive de-tection of data quality issues and facil-itating timely corrective actions. Ad-vanced analytics and machine learn-ing algorithms may be leveraged to au-tomate monitoring processes, flagging anomalies and deviations from prede-fined quality thresholds.

Artificial Intelligence (AI) is designed to create intelligent systems capable of performing tasks traditionally dependent on human intellect. Its integration into the field of education presents both opportunities and challenges as it is quickly expanding. Preparing teachers for this rapidly advancing technological shift is essential for success, as education itself is not static. This position paper adopts the methodology of synthesizing existing literature on innovative strategies for integrating AI into the preparation of Teachers of the Future. The concept of Teachers of the Future was introduced in this paper, addressing concerns surrounding AI’s potential to replace teachers. The paper recognized the irreplaceable roles of teachers in providing emotional and moral support as well as nurturing critical thinking among learners. It further explored the importance of AI for effective application in teaching and learning processes. Drawing upon the synthesis of literature collected from the review of related works, strategies for preparing Teachers of the Future in the Era of AI can be realized by implementing approaches such as development of AI literacy, integrating AI into teacher training courses, promoting collaborative learning among teachers in training, offering continuing education opportunities, and nurturing a positive attitude towards AI utilization. The paper suggested, among others, that Teachers of the Future should be provided with foundational training in AI application for teaching and learning processes within teacher education programmes offered by teacher training institutions.

A dialogue for the assurance of good digital governance. Development of the instrument ‘From Principles to Actions’ with scenario-based design thinking

When governments use digital technologies, public values can come under pressure. This article presents an instrument for governments to identify actions aimed at safeguarding public values concerning digital governance through dialogue. In the current literature there is a discrepancy between abstract discussions about good digital governance and the practical safeguarding of public values. The Dutch Code of Good Public Digital Governance (CODIO in Dutch) offers a framework, but not a concrete approach for organisations. To fill this gap, we have developed the CODIO ‘From Principles to Actions’ (VPA in Dutch) instrument based on literature on public value considerations concerning digitalisation. Based on scenario-based design thinking (SBDT), the CODIO and ethical guidance, we developed and tested the CODIO VPA instrument in three iterations at two Dutch provinces and a Dutch municipality. With the instrument, consisting of preparation, a workshop and follow-up conversations, government organisations can enter into dialogue about public values and identify concrete actions to strengthen public values. This research therefore results in an administratively substantiated and practice-tested instrument that helps government organisations to ensure good digital governance.

Published: June 2024

One of the most prevalent hormonal disorders affecting women who are of reproductive age is PCOS, a serious public health concern. Insulin resistance is significantly more common together with hirsutism, polycystic ovaries, and oligo/anovulatory periods as typical symptoms and  other multitude of chronic health issues that impact quality of life are linked to PCOS.PCOS patient and control group (non-PCOS) hormonal profiles are compared in this study.TSH, FSH, LH, and AMH are measured in this research. The results clarify the hormonal irregularities and consequences of PCOS.The data shows that women with PCOS had significantly greater AMH than controls, with a sensitivity and specificity of 93%.AMH has an NPV and PPV of 83% and 97%, respectively.The majority of PCOS patients reported higher LH levels than the control group, which had 86% sensitivity and 88% specificity. The LH level is impacted by PCOS, as seen by the 95% of PPV and 69%, of NPV.The FSH levels of controls and PCOS patients are comparable. Since FSH levels are comparable, the primary hormonal imbalance in PCOS is probably elevated LH and AMH. PCOS patients showed higher TSH levels than the control group, which may cause thyroid issues since 43% of PCOS patients had elevated TSH.These findings illuminate PCOS hormone abnormalities. Furthermore, people with PCOS are more prone than the general population to suffering from the morbidity related to metabolic and cardiovascular diseases.Understanding the hormonal imbalances linked to PCOS makes future research easier, which is required to understand the etiology of PCOS and hormone-regulated PCOS treatment.

Metodologicamente, adotou-se a abordagem qualitativa (Minayo, 2016), utilizando-se o estudo de caso como estratégia de investigação. Foram entrevistados dois profissionais atuantes na educação hospitalar, através da aplicação de questionários semiestruturados. Como centralidade teórica, temos o trabalho de Pereira (2017) além do uso normativo do Estatuto da Criança e do Adolescente (ECA/90). Para a análise dos dados obtidos, utilizamos a perspectiva compreensiva do Weber (1999). Os docentes entrevistados destacaram as particularidades inerentes a este contexto, as correlações de forças e os desafios enfrentados no processo de ensino-aprendizagem. Dentre essas particularidades, sobressaem-se as dificuldades e estratégias pedagógicas adotadas, os métodos de organização e atendimento aos alunos-pacientes durante o período de internação, bem como o acompanhamento desses estudantes na classe hospitalar. A pesquisa evidencia, assim, as especificidades do trabalho docente nesse ambiente, contribuindo para a compreensão dos desafios e das práticas educativas neste contexto singular.

Nos últimos anos, houve aumento significativo na expectativa de vida e melhora na saúde de indivíduos com Síndrome de Down (SD), devido, principalmente, à prevenção das complicações relacionadas à SD. O objetivo foi avaliar a frequência de fatores de risco para aterosclerose, prática de atividade física e história familiar de risco para doenças cardiovasculares em crianças e adolescentes com Síndrome de Down e cardiopatia congênita acompanhados em um serviço de atendimento multidisciplinar realizado no Ambulatório de Cardiologia Pediátrica do Instituto de Cardiologia do Rio Grande do Sul. Trata-se de um estudo transversal, exploratório e descritivo, envolvendo crianças e adolescentes com Síndrome de Down e Cardiopatia Congênita, uma amostra por conveniência. Foram estudados dados antropométricos, pressão arterial, perfil lipídico, atividade física diária e frequência de fatores de risco familiar para aterosclerose. Foram avaliados 68 indivíduos com Síndrome de Down. A presença dos fatores de risco familiar foi maior para hipertensão arterial, doença arterial coronariana, dislipidemia e obesidade. Apresentou maior prevalência de crianças e adolescentes ativos, 19,1% classificados como muito ativo e 45,6% como ativo. Níveis pressóricos adequados quando avaliados com percentil < 90 para idade e altura, perfil lipídico dentro da normalidade, 33,8% com C-HDL ≥ 45mg/dL, 76,5% com C-LDL ≤ 110mg/dL e 57,4% com triglicerídeos ≤ 90mg/dL. Os resultados deste estudo mostraram que as crianças e adolescentes atendidas neste Centro de Referência em Cardiologia com equipe multiprofissional, são fisicamente ativos, com pouca alteração patológica em valores pressóricos e valores lipídicos para sua faixa etária.

A crescente ocorrência de movimentos de massa de solo representa um risco significativo ao ambiente e à vida humana, pois têm implicações diretas na qualidade do solo e da água e, consequentemente, na produtividade agrícola e sustentabilidade ambiental. Apesar da predominância midiática sobre este fenômeno em áreas urbanas, é inquestionável o impacto causado por esses eventos também na área rural, recaindo substancialmente sobre áreas agricultáveis.  Assim, este estudo apresenta o conceito e os tipos de movimentos de massa, as condições de ocorrência e as formas de controle recomendadas na agricultura. Para tanto, foi realizado um levantamento de dados bibliográficos de caráter descritivo, qualitativo e exploratório em livros técnicos e plataformas de pesquisa Scientific Electronic Library Online (SCIELO), Portal de Periódicos CAPES/MEC, fontes governamentais e Google Scholar (Google Acadêmico). O movimento de massa refere-se a qualquer deslocamento de solo e rochas que pode ocorrer em encostas muito íngremes a partir de grandes precipitações. Inclui os seguintes tipos: erosão do solo; quedas, tombamentos e rolamentos; deslizamentos e corridas de massa; e subsidências e colapsos. Em ações de prevenção e controle em áreas agrícolas, o respeito à aptidão de uso do solo deve ser premissa básica, bem como a adoção de manejo e práticas conservacionistas integradas. Como a participação da comunidade é fator essencial na implantação e perenidade dos trabalhos de conservação do solo e da água, é importante que os programas e ações sejam implementados de forma descentralizada e participativa, a nível de microbacia hidrográfica, a fim de viabilizar uma abordagem sistêmica no planejamento conservacionista. Verificou-se a carência de políticas públicas claras e eficazes para o enfrentamento de movimentos de massa em propriedades rurais. Entretanto, o desafio que se apresenta tem caráter não apenas técnico, mas também social e econômico. Assim, atuam nesse sentido o serviço estatal de Assistência Técnica e Extensão Rural (ATER), e alguns instrumentos de incentivos fiscais vinculados a políticas públicas pontuais voltadas para o manejo sustentável, como o Pagamento por Serviços Ambientais, o Programa de Regularização Ambiental e o Programa de Agricultura de Baixo Carbono.

A Albizia pedicellaris é uma espécie nativa das florestas brasileiras que contribui para a biodiversidade das matas nativas, auxiliando na manutenção das características edafoclimáticas da região. Essa espécie apresenta elevado número de sementes quando atinge o estágio reprodutivo, no entanto, essas sementes apresentam dormência tegumentar, prolongando o tempo de germinação, sendo esses os fatores limitantes para a obtenção uniforme de mudas. Desta forma, objetivou-se no presente trabalho, avaliar diferentes métodos pré-germinativos para promover a superação de dormência das sementes de Juerana branca (Albizia pedicellaris), visando obter o maior número de plântulas normais. O experimento foi conduzido no Laboratório Didático de Análise de Sementes da Universidade Federal Rural da Amazônia, Campus sede, em Belém do Pará. Utilizou-se os seguintes métodos de superação de dormência de sementes ortodoxas: sementes intactas (T1), desponte das sementes (T2), desponte mais embebição em água por 24h (T3), imersão das sementes em ácido sulfúrico a 10 minutos (T4), imersão das sementes em ácido sulfúrico a 20 minutos (T5), imersão em hipoclorito de sódio a 2,2% durante 3h (T6) e imersão em hipoclorito de sódio a 1,1% durante 3h (T7). O delineamento experimental utilizado foi o inteiramente casualizado, contando com sete tratamentos, contendo quatro repetições. Foi calculado o peso de 1000 sementes, determiando-se o teor de água de 4 repetições de 40 sementes, por meio do método de estufa a 105ºC (±3) por 24h. Os testes pré-germinativos foram realizados em papel toalha germitest®, a incubação foi feita em câmara de germinação (Biochemical Oxygen Demand - B.O.D), a 25ºC (±3) durante 10 dias, onde se estabeleceu a germinação dos melhores tratamentos. Foram analisados os parâmetros de germinação (%G), o índice de velocidade de germinação (IVG), o tempo médio de germinação (TMG), Comprimento da parte aérea (CPA) e comprimento da raiz (CR) de plântulas normais. Foram determinados os pesos de massa seca da parte aérea (MSPA) e massa seca da raiz (MSR), no final do experimento analisou- se o número de plântulas normais, plântulas anormais, sementes duras e sementes mortas. Os dados foram submetidos à análise de variância por meio do teste Student-Newman-Keuls (SNK) a 5% utilizando o softwere R-Studio. As sementes de A. Pedicellaris respoderam bem aos tratamentos cuja imersão se deu em ácido sulfúrico a 10 min (T4) e 20 minutos (T5) e ao tratamento com desponte (T2), já o tratamento com desponte + embebição em água por 24 horas apresentou menor porcentagem de germinação e maior Número de sementes mortas. Sendo o tratamento com desponte (T2), o mais indicado para a produção de plântulas com mais de 80% de germinação e com custo mais barateado.
