“I don’t have an answer for you. I need to hear your thoughts”: a teacher’s deliberate mentoring practice in coplanning with student teachers

ABSTRACT Using educative mentoring as a framework, the study explored in-depth the beliefs and mentoring practices of a master teacher and his three student teachers’ (PSTs) perceptions and responses to the practice in a weekly one-hour coplanning meeting for a semester. Data sources included observations and video recordings of coplanning meetings, field notes, individual interviews with participants, PSTs’ journal entries, and documents such as weekly lesson plans. All video recordings and interviews were transcribed verbatim. The results showed that both intellectually and emotionally secure learning foundations are essential for learning, mentoring, and collaboration; deliberate mentoring practices such as challenging questions, exploratory thinking, modeling, and guiding reflection help PSTs shift their way of thinking and promote an inquiry mind-set; empowering PSTs in decision-making leads to genuine collaboration and creates learning opportunities. Through intentional mentoring, PSTs become confident, experimental, and creative change agents. The complexities of mentoring practice are then discussed. To support mentors in their preparation, a comprehensive and holistic approach to mentoring practice is proposed.

Study protocol for a multicenter randomized controlled trial on simulation-based communication training for pediatric cardiology trainees (SIMUL-CHD).

Effective physician-patient communication is crucial to compassionate healthcare, particularly when conveying life-altering diagnoses such as those associated with congenital heart diseases. Despite its importance, medical practitioners often face challenges in communicating effectively. Because of these gaps, we aim to introduce a simulation-based training protocol to improve pediatric cardiology trainee's communication skills. This study will be conducted in collaboration with associations supporting caregivers of children with congenital heart disease. It strives to demonstrate how specific training programs can efficiently foster humanistic, patient-centered care in standard medical practice. This multicenter, open-label randomized controlled trial will be conducted in pediatric cardiac units and simulation centers of across 10 universities in France. The study population comprises pediatric cardiologists in training (including pediatric cardiac fellows or specialist assistants). The SIMUL-CHD intervention will consist of simulation-based training with standardized patients, focusing on improving communication skills for pediatric cardiology trainees during diagnostic counselling. Patients and caregivers have been recruited from a National Patient Association named "Petit Cœur de Beurre". The primary outcome is the quality of physicians' communication skills. The evaluation committee, which will review video recordings of the sessions, will be blinded to which participants received simulation-based training (group of interest) and which received theory-based training (control group). Secondary outcomes are the effect of SIMUL-CHD on empathy and anxiety levels in young pediatric cardiologists. Baseline scores pre and post-intervention will be compared, and skill improvement resulting from the intervention measured. Simulation-based training has proven efficacy in teaching technical skills in various scenarios however its application to communication skills in pediatric cardiology remains unexplored. The involvement of experienced parents provides a unique perspective, incorporating their profound understanding of the emotional challenges and specific hurdles faced by families dealing with congenital heart disease. This trial is registered with the OSF registry (registered https://osf.io/ed78q ).

The dynamic relationship between enjoyment and anxiety in monologue communication tasks of Arab female EFL undergraduate students: an idiodynamic approach

Foreign language learners experience fluctuations in their levels of enjoyment and anxiety during communication tasks as they navigate communication challenges. These emotional surges can impact cognitive resources and speech-processing ability. However, there is scant empirical evidence on the associations between emotions at the personal level during foreign language learning (FLL) communication task performances. To address this gap, the present study utilized the idiodynamic approach to investigate the relationship between enjoyment and anxiety in monologue tasks performed by Arab Female undergraduate learners of English as a foreign language (EFL). Participants rated their emotions on a per-second basis after watching a video recording of their task performances and were interviewed about the reasons for fluctuations in their ratings. The study found that the negative relationship between anxiety and enjoyment varied from strong to moderate across 30 segments of speech per person. The emotions of anxiety and enjoyment were analyzed through triangulation of ratings, prompted recall interviews, and performance data. As a result of this investigation, four distinct sets of factors that affected these emotions were identified: Task execution (such as pre-task preparation and time constraints), task layout (including its structure and theme), cognitive-linguistic factors (such as transient disruptions in conceptualization and formulation speech processes), and performance measure (including assessment of one’s own linguistic proficiency).

Engaging with Culturally and Linguistically Diverse Communities to Promote Palliative Care That Exceeds Expectation.

Given longstanding barriers that obstruct integrated palliative care, particularly for culturally and linguistically diverse communities, this article demonstrates a way to engage with Syrian, Bhutanese and African communities to learn about brilliant palliative care with and from members of these communities. This study involved the methodology of POSH-VRE, which combines positive organisational scholarship in healthcare (POSH) with video-reflexive ethnography (VRE). Members of the Syrian, Bhutanese, and African communities (n = 14) participated in a focus group or an interview to consider understandings of palliative care; conceptualisations of a good death; how and why palliative care was typically enacted in their communities; the associated effects; as well as the relationship between culturally and linguistically diverse communities and public palliative care services. Discussions were aided by video recordings captured during the previous study on brilliant palliative care, which participants were invited to review. Video recordings and transcripts of the focus groups and interview were analysed using reflexive thematic analysis. The participants demonstrated considerable variability in the ways that palliative care was understood and enacted. For some, death was a taboo topic, while for others, it was a reality that was required to face, particularly in war-torn regions. Similarly, while doctors were held in high regard, participants held different views about how they should enact palliative care and the anticipation of death, particularly because family members were deemed to be a pivotal part of palliative care. To improve the care of people of culturally and linguistically diverse communities who experience a life-limiting illness, participants highlighted three opportunities. These included the avoidance of generalisations, prioritising the needs and preferences of cultural groups, and leveraging the community network. This study demonstrated how reciprocal understandings of palliative care were potentiated using POSH-VRE. Specifically, the members of the Bhutanese, African and Syrian communities demonstrated diversity in the needs, preferences, and customs of culturally and linguistically diverse communities. As such, integrated palliative care is likely to be bolstered by relinquishing assumptions about how cultural groups wish to be referred to and cared for and adopting a public health approach to palliative care that embraces both a population-based and person-centred approach to care. Members of the Bhutanese, African and Syrian communities contributed to this study as participants and co-researchers, contributing to the analysis and interpretation of the data and in the preparation of the article.

Developing and Evaluating SEE-Diabetes: A Patient-Centered Educational Decision Support System for Diabetes Car.

This feasibility study evaluated the effectiveness of Support-Engage-Empower-Diabetes (SEE-Diabetes), a patient-centered educational tool designed to promote shared decision-making of diabetes management in older adults. We aimed to assess SEE-Diabetes's ability to facilitate patient engagement and collaborative goal setting, as measured by the Observational Patient Involvement (OPTION) scale and Shared Decision-Making Questionnaire (SDM-Q-Doc). We hypothesized that these instruments would effectively differentiate between healthcare providers who actively leveraged SEE-Diabetes to guide patient-centric conversations and set goals compared to those who did not. SEE-Diabetes, developed through a 4-year user-centered design process, was employed in simulated clinical encounters at the University of Missouri Health Care. We conducted an analysis of 12 clinical encounters using video recordings. This analysis involved three simulated patients and four providers, two internals and two externals, utilizing a mixed-methods approach. We assessed the decision-making process using SEE-Diabetes by SDM-Q-Doc, OPTION scale, and conversation analysis. The average scores for the SDM-Q-Doc and the OPTION scale, out of a possible 100, were 52.6 and 75.9, respectively. Our findings revealed that active provider engagement with SEE-Diabetes during patient interactions served as an effective medium to facilitate shared decision-making and to set patient-centered goals. Providers who actively utilized SEE-Diabetes to guide conversations, ask open-ended questions, and incorporate patient input into goal setting demonstrated significantly higher OPTION and SDM-Q-Doc scores compared to those who used the tool less frequently or primarily for documentation purposes. Providers expressed positive feedback, highlighting its conciseness, patient-centricity, and optimism about integrating SEE-Diabetes into their future practices. SEE-Diabetes showed considerable promise in improving interactions between patients and providers, presenting an innovative approach to diabetes management for older adults. This tool has the potential to not only close communication gaps but also enable patients to take a more active role in their healthcare decisions.

Sense‐Making Through Hybrid Talk: High‐Achieving Secondary Students' Language Use during Practical Work

ABSTRACTThis study contributes to discussions on facilitating students' sense‐making in science by analyzing the utterances of high‐achieving students in dialogues during practical work and identifying characteristics of their language use and learning processes. The context of the study is a general science course at an upper secondary school in Norway. During four lessons, students from two classes conducted three exercises in electrochemistry. Data consist of video recordings from group work and whole‐class dialogues, students' written explanations, and their grades in science. Using the Bakhtinian concept of hybrid constructions (i.e., utterances including both vernacular and scientific elements), we analyze dialogues about scientific concepts and possible explanations for observations made during practical work. The analysis focuses on mixed‐ability groups that include one or two high‐achieving students. These students' successful learning processes enable the identification of language use that is part of sense‐making dialogues. We found that all students participating in dialogues used a mixture of vernacular talk, hybrid constructions, and scientific language during their learning processes. The content of scientific explanations proposed by high‐achieving students initially tended to be correct but superficial. The content then became more complex and hybrid and displayed errors and inaccuracies when students discussed detailed explanatory mechanisms, and finally, it became complex and largely correct. The results indicate that the high‐achieving students' use of hybrid constructions during practical work was beneficial for their learning. We discuss challenges related to creating situations in science teaching that encourage all students to engage in hybrid talk during sense‐making dialogues.

Potential of accelerometer tags for monitoring of Japanese quail (Coturnix japonica) reproductive behaviour

ABSTRACT 1. Monitoring behavioural dynamics in complex animal environments, such as poultry breeding facilities, poses a challenge. Utilising technological approaches, such as accelerometers, offers a solution to assess long-term changes in reproductive activity at an individual bird level. Specifically, these sensors measure acceleration associated with the position and movements of the body over time. However, it is important to assess the most suitable method for attaching accelerometer tags to ensure they do not negatively impact behaviour and yield high-quality data. 2. The potential of tri-axial accelerometer tags for assessing reproductive behaviour in Japanese quail was evaluated. Two attachment methods – a backpack (plastic platform with elastic bands near wing bases) and a patch (accelerometer on fabric glued to the synsacrum region) – were compared. Controls were handled similarly but without tags. Eighteen pairs of females were housed in pens and assessed immediately and 24 h after handling. After a week of habituation, a male from the same treatment group was introduced into each pen on d 8. The reproductive behaviour of the males was recorded using accelerometers and video recordings. 3. The results showed that birds with patches were able to remove their conspecific’s accelerometer and displayed an increased initial immobility response compared to the control and backpack groups. The presence of accelerometer tags did not impact male/female reproductive interactions nor fear responses to a novel object. From accelerometer recordings, male reproductive behaviour was easily identified as high amplitude fluctuations in the three axial components of the acceleration vectors, which was reflected as large values of dynamic body acceleration (VeDBA). 4. In conclusion, the use of backpacks with accelerometers is a useful strategy to address highly relevant and difficult to tackle behavioural topics such as the temporal dynamic of male reproductive behaviour within breeding groups.

Assessing the use of remote underwater video (RUV) to identify fish and their feeding behaviour in New Zealand's Greenshell™ mussel (Perna canaliculus) farms

Fish predation poses a significant and escalating challenge for the global mussel aquaculture industry. In New Zealand, Greenshell™ mussel farms experience crop losses of up to 100 % that are anecdotally attributed to fish predation, although the fish species responsible have not been confirmed. In this study, remote underwater video (RUV) was used to observe fish activity within four mussel farms at different stages of production in the Firth of Thames, New Zealand. The RUV enabled the identification of the fish species inhabiting mussel farms, including those responsible for predating cultured mussels. Four fish species were identified as frequent inhabitants of the mussel farms, with Australasian snapper (Chrysophrys auratus) and parore (Girella tricuspidata) the most abundant at three out of four mussel farm sites. Australasian snapper was the most common predator, taking as many as 2880 bites of the dropper lines holding mussels in a single 11 min 47 s video recording. Snapper formed feeding aggregations around dropper lines holding juvenile mussels (> 20 mm SL), indicating their potential to remove mussels from nursery farms in a short amount of time. Observations of the feeding behaviour of parore indicated their potential to contribute to the losses of mussels on recently seeded spat farms with these fish recorded tearing apart seeded lines, possibly targeting the macroalgae that is seeded out with the mussel spat. Besides confirming the identity and the predatory behaviour of fish species that are contributing to crop losses from mussel farms in New Zealand, this study also confirms the effectiveness of RUV methods for this purpose. This knowledge can be used to begin to develop mitigation strategies aimed at reducing crop losses in mussel aquaculture.

An Integrated Portable System for Laser Speckle Contrast Imaging and Digital Holographic Microscopy

A multimodal quantitative phase imaging platform combining digital holographic microscopy (DHM) with laser speckle contrast imaging (LSCI) is demonstrated for imaging weakly scattering and transparent samples in a label-free manner. It uses the principle of coherence of the light source for interferometric detection of phase of transparent and semi-transparent samples. The speckle formation resulting from the coherence property of the laser source is used to track dynamic activities in the regions of interest in the sample. Integration of these two techniques onto a microfluidic chip leads to an optofluidic real-time microscope for live cell imaging applications. In this work, we have developed an integrated multimodal system combining digital holographic microscopy and laser speckle contrast imaging system for Optofluidics and in vitro studies. The sample flowing through the microfluidic channel is imaged to record holograms and video of intensity images at the same time. This enables to map the flow within a microfluidic channel and quantify the channel as well as the particle flow through the channel. The channel morphology along with the particles flowing through the channel are quantified using DHM. The two-dimensional speckle contrast images map the flow of the dynamic microbeads and cells with very high contrast in almost real time. A low-cost portable multimodal quantitative phase microscope combining DHM and LSCI has been demonstrated for real time imaging with applications in optofluidics.

Аналіз змагальної діяльності юних спортсменів на 38-му дитячому турнірі «Ванпаку сумо»

Purpose: to analyze the competitive activity of young athletes at the 38th «Wanpaku Sumo» Children's Tournament. Material and methods. The following methods were used in the study: analysis of scientific and methodological information and Internet sources; generalization of best practices; analysis of protocols and video recordings of matches. A total of 293 fights were analyzed (92 fights among fourth graders, 94 among fifth graders, 107 among sixth graders). For the analysis, a specialized computer program «Martial Arts Video Analysis» was used. Results: the analysis of competitive activity allowed us to identify the groups of techniques most often used by athletes during competitions. The most frequently used techniques of the group kihon waza (57,65 %). Athletes of all age groups actively used the basic technique (4th grade – 57,60%, 5th grade – 57,44 %, 6th grade – 57,94 %). The most common techniques in all age categories were yorikiri and oshidashi. Actions that occurred during the competition and belong to the hiwaza group and are not kimarite indicate that young athletes do not yet have perfect control over their bodies and can lose balance even without the intervention of an opponent. The analysis of technical actions allowed us to observe the progress of technique by grade. Thus, in the fifth grade, more complex techniques (harimanage and chongake) appear. This indicates that children are gradually mastering more complex techniques that require better coordination and tactical thinking. In the upper grades, the use of complex techniques such as tsukiotoshi and sotogake is observed. This indicates that participants are becoming physically stronger and more coordinated, which indicates a gradual mastery of more complex techniques. Conclusions. The analysis of the competition during the 38th «Wampaku Sumo» Tournament revealed some characteristic features. First, the competitions were highly intense. The yorikiri technique is the most effective, so it is very popular among young athletes. Although yorikiri dominates, the presence of other techniques such as koshinage and makiotoshi shows that participants have a diverse arsenal of techniques. In high school, participants begin to demonstrate better physical fitness, which helps them to use more complex techniques and endure bouts longer. Psychological pressure also plays a role, as participants are forced to make quick decisions and choose techniques that are most effective under pressure.

The Effects of Using Modern Technologies in the Neurorehabilitation Process of a Patient after Traumatic Brain Injury – A Case Study

This study presents an analysis of the case of a 44-year-old male patient who experienced a traumatic brain injury, resulting in spastic quadriplegia, meningitis, right-sided craniotomy, ventriculoperitoneal shunt placement, and right hip arthroplasty. Data was collected over a four-year comprehensive therapy process involving treatment periods, during which the patient was under the care of an interdisciplinary team and participated in an individualized rehabilitation program, consisting of 3-4 hours of physical therapy daily for 5-6 days per week. The material included results from functional tests, muscle tone assessments, and balance evaluations. Numerical data from robotic gait therapy devices were also considered. With the consent of the patient and his family, the therapy process was documented via video recordings and photographs, which were then used for a retrospective visual analysis of recorded material at various stages of rehabilitation. For this purpose, the ShapeCare.Fizjo device was used, along with Blaze Pose software, based on a moving person’s skeletal detection model. The results indicated that comprehensive therapy using innovative tools such as C-eye, ReoGo, ReoAmbulator, and LeviActive system improved the patient’s balance and motor skills, as well as facilitated the gait re-education process. The use of modern technologies in neurorehabilitation not only optimizes therapeutic outcomes but also reduces the risk of musculoskeletal strain for the therapist during their professional work.

Missing Responses as an Interactional Warning Sign

In this study, we aim to find out what happens in moments of collaborative situations when a response is treated as missing, irrelevant, or insufficient, how such moments are handled, and what underlying interactional trouble those instances can reveal. The data are video recordings from multinational military observer training. Using the method of ethnomethodological conversation analysis (EMCA), we examine a team of two people taking part in a simulated patrolling exercise. We focus on instances when one team member, the driver, attempts to get the other, the team leader, to verbalise or confirm some decision regarding a future (joint) action.

The Utilization Of Homework Videotaping To Enhance The Students’ English Speaking Skills

Enhancing students' oral proficiency is a key objective of English courses, and one effective pedagogical approach is assigning video-based homework that features English conversations aligned with the curriculum. English language students encounter numerous challenges when attempting to enhance their speaking abilities. One limitation is the restricted amount of time available for in-class practice. One possible homework assignment is to create video recordings. This offers a chance for students to enhance their creativity and boost their self-assurance as the homework encompasses various elements of oral assignments, such as productivity, intention, challenge and authenticity. Hence, this webinar aims to disseminate knowledge on the specific teaching methods and procedures that teachers can implement when utilising this instructional approach. The purpose of this webinar was to provide the teachers, instructors and practitioners in the field of English education with an interactive forum for discussion. Participants will have the chance to share their experiences and ask questions, which will lead to a fruitful exchange of knowledge. Engaging in activities can yield fresh perspectives and impart useful skills that are immediately applicable to the classroom or other educational setting.

The Development of AI-Powered Automatic Video Sign Language Translation Systems

People who are deaf or hard of hearing often face challenges in fully understanding written subtitles in videos due to the differences between sign language and spoken language, each having unique grammar and structures. While many social media platforms provide automatic subtitles, they are often insufficient for accessibility. Sign language interpretation should be included to make video content fully accessible. Traditionally, adding sign language to videos involves a time-consuming process of recording and embedding separate translation videos, which must be redone with any changes to the original video. The plugin simplifies this process by dynamically translating updates directly from subtitle files, significantly reducing the time, effort, and cost involved. It allows seamless sign language support for any video without modifying the original content. The plugin integrates with video players, providing a user-controlled, customizable sign language window that can be activated, moved, resized, or turned off as desired.

Time to Ring in the Body Checking, Head Contact, and Suspected Injury Rates in Youth Ringette: A Video-Analysis Study in Youth Ringette and Female Ice Hockey.

To compare physical contacts (PCs), including head contacts (HCs), suspected concussion, and nonconcussion injury incidence rates between youth ringette and female ice hockey. Cross-sectional. Alberta ice arenas. Players participating in 8 U16AA (ages 14-15 years) ringette and 8 U15AA (ages 13-14 years) female ice hockey games during the 2021 to 2022 season. Dartfish video-analysis software was used to analyze video recordings. Univariate Poisson regression analyses (adjusted for cluster by team-game, offset by game minutes) were used to estimate PCs (including HCs) and suspected injury (concussion and nonconcussion) and concussion-specific IRs and incidence rate ratios (IRRs) to compare sports. Proportions of all PCs that were body checks (level 4-5 trunk PC) and direct HCs (HC1) penalized were reported. Ringette had a 2.6-fold higher rate of body checking compared with hockey (IRR = 2.63, 95% CI: 1.59-4.37). Ringette also had a 2-fold higher rate of HC1 compared with hockey (IRR = 2.08, 95% CI: 1.37-3.16). A 3.4-fold higher rate of suspected injury was found in ringette (IRR = 3.37, 95% CI: 1.40-8.15). There was no significant difference in suspected concussion IRs in ringette compared with hockey (IRR = 1.93, 95% CI: 0.43-8.74). Despite being prohibited in both sports, only a small proportion of body checks (Ringette = 18%; Hockey = 17%) and HC1 (Ringette = 6%; Hockey = 6%) were penalized. Higher rates of body checking, HC1, and suspected injuries were found in ringette compared with female ice hockey. Body checking and HC1 were rarely penalized, despite rules disallowing them in both sports. Future research should consider other youth age groups.

Reliability and objectivity of the new version of the 'susceptibility test for body injuries during a fall' (STBIDF-M) in physiotherapy students

Background and Study Aim. Falls are a global public health and economic challenge. Since falls are often unavoidable, it is crucial to focus on preventing injuries caused by the impact with the ground. The aim of this study was to verify the reliability and objectivity of the STBIDF-M. Material and Methods. The sample included 30 male (n = 9) and female (n = 21) physiotherapy students (age 20.97 ± 1.16 years; weight: 66.5 ± 12.06 kg; height: 171 ± 9.62 cm). The STBIDF-M was administered twice, with the second measurement (retest) conducted seven days after the first (test). A method of direct secondary observation, allowing for multiple replays, was used. The assessment involved reviewing video recordings of both stages (test and retest) by three experts experienced in using the STBIDF-M. Results. Each expert observed a tendency to reduce errors during the 'retest' compared to the 'test' stage. This was measured by the arithmetic mean. Statistically significant differences were found in tasks 3, 4, 5, 6, and in the IndexSBIDF-M based on the experts' agreed assessments. Three students (10%) repeated their results from the 'test' stage, showing full correlation. Twenty students (66.67%) demonstrated a tendency to reduce errors. The IndexSBIDF-M 'test-retest' results showed a very high positive correlation (r = 0.810, p < 0.01). This indicates a statistically significant impact of motor modifications in most students. Specifically, clapping hands during Task 3 and pressing the sponge to the body with the chin during Task 4, simulating a backward fall, helped reduce errors. These reductions were noted during ground impact as the degree of coordination difficulty increased in subsequent tasks. Conclusions. The results of this 'test-retest' procedure demonstrate the flexible, non-standardized possibilities of analyzing and synthesizing data using this basic method. This flexibility is attributed to the innovative motor structure of the STBIDF-M, which goes beyond traditional methodological approaches. Observing the unconscious behaviors and actions of the participants has provided valuable insights into inferential phenomena related to the mental and intellectual aspects of human personality.

Avatar Detection in Metaverse Recordings

The metaverse is gradually expanding. There is a growing number of photo and video recordings of metaverse virtual worlds being used in multiple domains, and the collection of these recordings is a rapidly growing field. An essential element of the metaverse and its recordings is the concept of avatars. In this paper, we present the novel task of avatar detection in metaverse recordings, supporting semantic retrieval in collections of metaverse recordings and other use cases. Our work addresses the characterizations and definitions of avatars and presents a new model that supports avatar detection. The latest object detection algorithms are trained and tested on a variety of avatar types in metaverse recordings. Our work achieves a significantly higher level of accuracy than existing models, which encourages further research in this field.

Effect of video-based exercise on premenstrual symptoms: a randomized controlled trial.

This study aims to investigate the impact of Pilates exercises on premenstrual syndrome (PMS) symptoms, perceived stress levels, and pain intensity. Forty-six women with PMS participated in this study and were assigned to the intervention and control groups based on their willingness to participate. The intervention group undertook Pilates practices via video recording twice a week for 8 weeks, while the control group did not engage in regular exercise during the same period. PMS symptoms were assessed using the Premenstrual Syndrome Scale (PMSS), premenstrual stress levels were evaluated using the Perceived Stress Scale (PSS), and premenstrual pain levels were assessed using the McGill Melzack Pain Questionnaire (MPQ) at both the beginning and end of the study. There was a significant difference observed in the PMSS, PSS and MPQ evaluations of the intervention group following their participation in Pilates practices (p < 0.05). Conversely, no significant difference was observed in the PMSS, PSS and MPQ evaluations of the control group at the end of the study (p > 0.05). There was no statistically significant difference between the two groups in PMSS evaluation (p > 0.05) at the end of the study. However, a statistically significant difference was detected in PSS and MPQ evaluations (p < 0.05). Pilates exercise can affectively decrease the perceived stress level and pain severity in PMS affected women. This study highlights the efficacy of Pilates for physiotherapists in PMS symptom reduction. Moreover, the implementation of a self-guided video-based home exercise program could provide patients with practical and time-efficient alternatives.

FRAGMENTE2

The exposition provides an insight into the collaborative process of creating and performing Fragmente2 (2021) a choreomusical work by musician Kerstin Frödin and choreographer-dancer Åsa Unander-Scharin based on the Japanese avant-garde composer Makoto Shinohara’s solo piece for tenor recorder, Fragmente (1968). The exposition is an attempt to describe the methodology and creative process in this project, wherein music and dance intertwine in a non-hierarchical manner. The exposition follows the structure of the performance, which consists of a series of fragments, each of them analysed and descibed in terms of choreomusical interaction. We used Don Ihde’s experimental phenomenology and perspective variation (1986) as an artistic method to analyse and explore different aspects of our choreomusical materials and interaction concepts. To address and elaborate the choreomusical elements, we used Maurice Merleau-Ponty’s distinction between abstract and concrete movements (1945/2012), Pierre Schaeffer’s musical objects (1966/2017), and our own concept of choreographic objects. Furthermore, to jointly analyse and evaluate different interaction concepts we used video recordings, annotated scores, choreography scripts, movement instructions, personal reflections, and metaphorical descriptions of the 17 fragments. The process resulted in a contrapuntal choreomusical work where music and dance act as equal parts.

Radiation and thermal embrittlement of RPV steels: the links of embrittlement mechanisms, fracture modes and microcrack nucleation and propagation. Part 2. Strength and plasticity properties

The uniaxial tension test results are represented over wide temperature range for smooth round bars of 2Cr–Ni–Mo–V steel and A533 steel used for RPVs of WWER and PWR types. These steels are studied in the following states: (1) the initial (as-produced) state; (2) the thermally embrittled state modelling hardening mechanism of embrittlement; (3) the thermally embrittled state modelling non-hardening mechanism of embrittlement; (4) the irradiated state. The true stress-strain curves are determined over wide temperature range that is required for calculation of the stress-and-strain fields for various specimens. The true stress-strain curves for the investigated steels in the initial and thermally embrittled states are obtained when using standard mechanical characteristics. For the irradiated steels the true stress-strain curves are obtained when using the data of the digital video recording under continuous in-testing monitoring of the cylindrical parts of tensile bars. For the irradiated materials the procedure based on standard characteristics cannot be used as it is connected with very small strain. The procedure based on the digital video recording data is verified by comparison of the stress-strain curves obtained for the initial and thermally embrittled states on the basis of the digital video recording data and standard characteristics.
