Much of what has been written about decreased work ability is based on quantitative studies and has been written from the perspective of professionals, service providers or authorities. In our qualitative study, we sought to understand how affected individuals themselves perceive and experience the multifaceted factors that are related to their decreased work ability. Sixteen individuals in Finland with musculoskeletal diseases (MSD) participated in semi-structured interviews. The participants were potential clients of a multi-professional service pilot model, the TOIKE Work Ability Centre. Narrative and thematic analyses were utilised. The study found that individuals with decreased work ability have differing perspectives towards returning to work and often complex life situations. Five distinctive groups were identified based on self-assessed health, work ability and orientation towards work or pension: (1) the Successful; (2) the Persevering; (3) the Forward-looking; (4) the Stuck; and (5) the Pension-oriented. Health problems, unemployment, age discrimination, financial difficulties and skill deficits were the major challenges of the interviewees. Furthermore, they perceived the service and benefit systems as complicated. The TOIKE service proved useful to some of them. However, many had not utilised it due to a lack of understanding of its purpose. Identifying the distinctive groups and their needs may improve interventions. Ultimately, this may help to achieve Target 8.5 of the UN Sustainable Development Goals, which advocates the right to employment for all ages and for those with disabilities.

To assess the effects of the mill operating parameters such as mill speed, ball filling, slurry concentration and slurry filling on grinding process and size distribution of mill product, it was endeavored to build a pilot model with smaller size than the mill. For this aim, a pilot mill with 1 m × 0.5 m was implemented. There are 15 lifters with 50 mm height and face angle of 30˚. In the present work, the combination of the balls (40% of the balls with 60 mm diameter, 40% of the balls with 40 mm diameter and 20% of the balls with 25 mm diameter) was used as grinding media with 10%, 15%, 20% and 25% of the total volume of the mill. The experiments were carried out at 60%, 70%, 80% and 90% of the critical speed. The feed of the mill is copper ore with the size smaller than 25.4 mm, which d80 and d50 of them are 12.7 and 8 mm, respectively and slurries with 40%, 50%, 60%, 70% and 80% of solid and the slurry filling between 0.5 and 2.5. The results showed that the best grinding and grading occurs at 70–80% of the critical speed and ball filling of 20–25%. Optimized grinding was observed when the slurry volume is 1–1.5 times of the ball bed voidage volume and the slurry concentration is between 60% and 70%. The mill grinding mechanism in this work is a combination of both impact and abrasion mechanisms.

This article reviews the research findings from a student evaluation of a pilot study of peer-led group supervision for undergraduate social work students at a university in the UK. The definition, purpose and concept of peer-led group supervision are considered and the pilot model and intended learning outcomes described. The student evaluation provides positive feedback that this group setting allowed for support, knowledge exchange and an opportunity to discuss learning from placement experiences. Constructive student feedback enables further discussion in regard to the logistical set-up of this group learning environment and the role of an observing Practice Educator/link tutor. Recommendations are made for how this model can be developed in the future to further the learning opportunities for social work students using this peer-led group supervision model.

Abstract Background Due to the outbreak of the coronavirus disease 2019 (COVID-19), it proved necessary to rapidly change medical education from on-site to online teaching. Thus, medical educators were forced to rethink the purpose of teaching and the best form of transmission of knowledge. In cooperation with the European Society of Radiology (ESR), we investigated the attitudes of radiologists in Europe and North America toward innovative online teaching concepts. Methods In total, 224 radiologists from 31 different countries participated in our cross-sectional, web-based survey study. On a 7-point Likert scale, participants had to answer 27 questions about the online teaching situation before/during the pandemic, technical and social aspects of online teaching and the future role of online teaching in radiology. Results An overwhelming majority stated that radiology is particularly well-suited for online teaching (91%), that online teaching should play a more prominent role after the pandemic (73%) and that lecturers should be familiar with online teaching techniques (89%). Difficulties include a higher workload in preparing online courses (59%), issues with motivating students to follow online courses (56%) and the risk of social isolation (71%). Before the pandemic, only 12% of teaching was provided online; for the future, our participants deemed a proportion of approximately 50% online teaching appropriate. Conclusion Our participants are open-minded about online teaching in radiology. As the best way of transferring knowledge in medical education is still unclear, online teaching offers potential for innovation in radiology education. To support online teaching development, a structured, framework-based “online curriculum” should be established.

This paper presents the design and modeling of a flying-type fire extinguishing system. Fire accidents present very hazardous environments, and firefighters are in danger of losing their lives while putting out the fire. Strict safety measures should be considered to guarantee safe working conditions for firefighters, which is not the case every time, as fatalities and casualties are still being recorded. For this reason, a novel fire extinguishing system is proposed to provide more safe firefighting and survivor searches. The system studied in this paper is a pilot model that consists of a water jet-based actuation system to control the flying motion of the robot. The dynamic model of this flying robot is derived using the actuation forces, water jet system characteristics, and related information. The mathematical system model is detailed, a sliding-mode control system and a proportional-integral-derivative controller are designed, and comparative simulation tests are carried out.

Abstract Pilot-Induced Oscillation (PIO), although an old issue, still poses a significant threat to aviation safety. The introduction of new systems in modern aircraft modifies the human–machine interaction and makes it necessary for research to revisit the subject from time to time. Given the need of aircraft manufacturers to constantly perform PIO tests, this study analysed the feasibility of using three different computational pilot models (Tustin, Crossover and Precision) to simulate PIO conditions. Three aircraft models with different levels of propensity to PIO (original, low propensity and high propensity) were tested, as well as two pilot gain conditions (normal and high). Data were collected for a purely longitudinal synthetic task through simulations conducted in MATLAB®. PIO conditions were detect using a tuned PIO detection algorithm (ROVER). Data were analysed in terms of both whether the pilot models triggered a PIO condition and for how long the condition was sustained. The results indicated that the three pilot models only provoked PIO conditions when high gain inputs were applied. Additionally, Crossover was the only pilot model to trigger a PIO for the three aircraft models. There were also significant differences between the pilot models in the total PIO time, as the Tustin model typically sustained the oscillatory condition for longer.

Arabic is considered one of the most important components that constitute the national, cultural, individual, and collective identity of the Arab pupil. On the one hand, it has a fundamental role in the pupil’s life because through it, he expresses his thoughts, his feelings, and his needs. On the other hand, through it, he acquires and creates knowledge. However, this language is facing a lot of challenges that make the mission of teaching Arabic a complex one due to the phenomenon of diglossia, of colloquial Arabic ('Ammiyya/Darija) and Standard Arabic (Fusha). People throughout the Arab world communicate in their local dialects of colloquial Arabic while standard (fusha) Arabic is used only on formal occasions, in official correspondence, and at governmental offices.          The challenges of the era and the development of technology and sciences, and people’s resort to teaching courses of distant learning, especially during the recent period of the Corona pandemic, created a need to develop new teaching methods that help the pupils master all the aspects and the four language skills: reading, listening, speaking and writing.          Since writing is the ultimate result that the pupil has to acquire and control perfectly, he also has to acquire a lot of skills and make a lot of follow-up. Due to this new development, I chose to focus in this research on a pilot model in teaching written presentation, which I have developed in response to the new circumstances and the need to provide Arabic teachers with new, systematic, gradual methods of teaching the writing skills that are based on the pupils’ needs, on the one hand, and the needs of the environment and the modern era, on the other. This study is an article in a series of forthcoming articles that will deal with teaching various literary genres through a pilot model of teaching written presentation. I chose to start here with the genre of imaginary fictional writing that is based on the existence of events of fantasy weaving, which cannot take place in reality due to the challenges and aesthetics that exists in this kind of fictional art.

Management of advanced-stage oral cancer adds a great burden to individuals and health care systems. Community-based oral cancer screening can be beneficial in early detection and treatment. In this study, a novel oral cancer screening program was conducted utilizing an existing network of health care personnel, facilities, and digital database management for efficient coverage of a large population. The screening program considered 392,396 individuals aged ≥40 from four northeastern provinces in Thailand. Three levels of screening were performed: S1 by village healthcare volunteers to identify risk groups, S2 by dental auxiliaries to visually identify abnormal oral lesions, and S3 by dentists for final diagnosis and management. A total of 349,318 individuals were interviewed for S1, and 192,688 were identified as a risk group. For S2, 88,201 individuals appeared, and 2969 were further referred. Out of 1779 individuals who appeared for S3, oral potentially malignant disorders (OPMDs) were identified in 544, non-OPMDs in 1047, doubtful lesions in 52, and no results in 136 individuals. Final treatment was carried out in 704 individuals that included biopsies of 504 lesions, exhibiting 25 cancerous lesions and 298 OPMDs. This study is so far one of the largest oral cancer screening programs conducted in Thailand and showed effective implementation of community-based oral cancer screening.
