Stability and instability are very important for the layout of real world processes concerning safety and health esp. when planned by scientists. The long‐term investigation of stability was carried out for the last ten years on the basis of the installation and the evaluation of an ergonomically designed outdoor illumination. In the depicted dynamic situation the lighting design influences directly visual discomfort and human performance and in the end stability and instability. The improvement of the adaptation of luminance and its influence on the visual tasks after the rearrangement are presented and discussed. The effective factors on the visual capability and performance of workers, work efficiency and potential accidents in the night shift, and furthermore the accelerators and barriers for the stability of the project are analysed and discussed.

The intent of this research is to explore how architecture can enlighten healing or provide spaces where healing can take place. The healing environments, make wellness centres less stressful and promote faster healing for patients and improve well-being for their families, as well as creating a pleasant, comfortable and safe work environment. Light impacts human health and performance by enabling performance of visual tasks, controlling the body’s circadian system, affecting mood and perception, and by enabling critical chemical reactions in the body. Natural light should be incorporated into lighting design in healthcare settings, not only because it is beneficial to patients and staff, but also because it is light delivered to people at no cost and in a form that most people prefer. Study involves comparing healthcare settings in warm and humid climatic zones and how day lighting plays an important role in healing. Appropriate day lighting thus impacts outcomes in healthcare settings by reducing depression among patients, decreasing length of stay in hospitals, improving sleep and circadian rhythm, lessening agitation among patients, easing pain, and improving adjustment to night-shift work among staff. The appropriate positioning and optimisation of windows/ openings in the workplace and access to daylight have been linked with increased satisfaction with the surrounding environment.

AimsDuring out of hour handovers at St Charles Hospital – the two duty SHO (senior house officers) cover on site, whereas the on-call registrar and consultant are available to contact by phone. Some trainees may experience difficulties in contacting their seniors for support, or may not feel comfortable doing so. Trainees may also feel like they would benefit from being more informed of the hospital situation, or added learning and educational opportunities from the shift. The aim of this project was to improve the out of hours support for the on-call SHOs – which we hope to have positive short (such as improving confidence and performance) - and longer-term impacts (improving retention in the deanery and specialty).MethodThe project proposed instating a 15-minute Zoom call at the start of each night shift (9:30pm) which involved the on-call team (SHOs, registrar, consultants and ideally bed managers). Firstly – a survey monkey questionnaire was sent to trainees to gain a baseline on how supported/informed/ease and learning opportunities for that shift. The project then piloted three separate Plan Do Study Act cycles of change and collected feedback from trainees after each cycle. Both qualitative feedback and quantitative feedback from trainees were collected in the Likert scale format after each PDSA cycle.ResultResults showed that a key benefit of this call is that any pressing issues can be brought up and addressed. Furthermore, for the benefit of the trainees, generally trainees felt more supported whilst they are on call, and got to know the fellow on call team. In addition, trainees reported feeling more at ease when calling their senior colleagues.ConclusionIt is particularly important for doctors to feel supported and informed during their on call shift, especially in the current climate, where there are fast changes and adaptations taking place due to the pandemic. By adding a short meeting at the beginning of each night shift, doctors in the hospital demonstrated an increase in feeling supported, informed and having educational opportunities during their on call shifts. In the long term, by addressing on call issues and making trainees feel more confident and supported during their shift, is likely to benefit and improve recruitment and retention.

In order to solve the problem of poor accuracy of traditional microcontroller attachment stability testing method, a microcontroller attachment stability testing method based on biosensor was designed to solve the existing problems. The reliability test index of the microcontroller is established, then the interference of the microcontroller accessory is detected and responded, and the interference detection signal of the microcontroller accessory is selected. The process design of stability detection of microcontroller accessories based on biosensor is completed. The experimental results show that the stability detection method based on biosensor designed in this paper can ensure the stability detection accuracy of microcontroller accessories above 80%, which is more accurate than traditional methods. It can be used to evaluate the stability, reliability and performance of microcontroller accessories in long-term operation.

Understanding is based on a large number of highly varied abilities called intelligence that can be measured. In this paper understanding abilities of the shape understanding system (SUS) are tested based on the adoption of the intelligence tests. The SUS tests are formulated as the tasks given to the system and performance of SUS is compared with the human performance of these tasks. The main novelty of the presented method is that the process of understanding is related to the visual concept represented as a symbolic name of the possible classes of shape. The visual concept is one of the ingredients of the concept of the visual object (the phantom concept) that makes it possible to perform different tasks that are characteristic for the visual understanding. The presented results are part of the research aimed at developing the shape understanding method able to perform the complex visual tasks connected with visual thinking. The shape understanding method is implemented as the shape understanding system (SUS).

This chapter addresses the achievements of state–mosque relations and the “incorporation” outcomes that can be measured so far. What is the stability and performance of Islam Councils across the countries? How have these policies conditioned integration outcomes and political moderation, and what impact do they have on the long-term prospects of Muslims' everyday integration in Europe? This chapter empirically traces the effects of European policy approaches and finds that they have had a dramatic effect on Muslim communities: their domestic orientation, their reformed organizational structures, their outspoken distancing from violence and radicalism, and their outward commitment to playing by the rules of the game. Host societies as well as Muslim community leaders—and the scope of their agendas—have been transformed by the experience of institutional integration.

This article addresses the functional links between knowledge and performance in human activity. Starting with the evolutionary roots of knowledge and activity, it shows how the combination of adaptive behavior and knowledge storage has formed over various stages of evolution. The cognitive architecture of human actions is discussed against this background, and it is shown how knowledge is integrated into action control. Then, methodological issues in the study of action knowledge are considered, and an experimental method is presented that can be used to assess the structure of action knowledge in long‐term memory. This method is applied in studies on the relation between object knowledge and performance in mechanics and between movement knowledge and performance in high‐performance sportswomen. These studies show how experts’ knowledge systems can be assessed, and how this may contribute to the optimization of human performance. In high‐level experts, these representational frameworks were organized in a highly hierarchical tree‐like structure, were remarkably similar between individuals, and matched well the functional demands of the task. In comparison, the action representations in low‐level performers were organized less hierarchically, were more variable between persons, and were not so well in accordance with functional demands. These results support the hypothesis that voluntary actions are planned, executed, and stored in memory directly by way of representations of their anticipated perceptual effects. The method offers new possibilities to investigate knowledge structures. Based on such results it is possible to improve performance via special training‐techniques. This paper fulfils an identified research need concerning the interaction of knowledge and performance and offers new perspectives for future forms of knowledge management.

Abstract BackgroundRoot microbiome is critical for plant health and performance. Many studies have assessed the impact of agricultural management on soil microbiome. But a comprehensive understanding of how root microbiota is affected by soil types and fertilization is still lacking. It is clear yet whether the stability of root microbiome is affected by fertilization regimes, and whether in the same patterns as soil microbiome. MethodsWe conducted a long-term experiment and investigated the impact of soil type, plant type and fertilization regimes on soil and root bacterial communities using high-throughput sequencing and network analysis.ResultsOur results indicated that microbial network under combined organic-inorganic fertilization had higher stability than exclusive inorganic or organic fertilizer. In addition, fertilization exhibited stronger effects on root microbiome than on soil microbiome. While total nitrogen mainly contributes to the variance of root microbiome, pH and soil organic matter were responsible for the differences of soil microbiome. Bacteroidetes and Firmicutes appeared as important drivers in soil and root microbiome amended with organic fertilizer, whereas Actinobacteria was enriched in the soil microbiome under inorganic fertilizer. ConclusionsOur results clearly indicated the responsive shifts of soil and root microbiome to different fertilization regimes, and gave hints for developing better fertilization practices and establishing healthy root associated microbiota.

<p><em>The purpose of this study is  to evaluate the effect of shift work on level of fatigue and  performance of railway controller. Seventeen participants are the railway controller of Bandung Station. Fatigue was measured using subjective questionaire Swedish Occupational Fatigue Inventory (SOFI) and performance was measured using Psychomotor Vigilance Task based on reaction time.  Friedman test and Bonferonni-Dunn test were used to process data. Statistical analysis indicates there was significant difference level of fatigue and human performance between shift work. Fatigue occurs at sleepiness, phsysical discomfort and lack of motivation dimensions, while performance occurs at mean 1/RT, fastest 1/RT and slowest 1/RT (P &lt; 0,10). %. The highest fatigue and the worst performance occurs after night shift. After night shift, the level of fatigue increased about 37% to 162%, meanwhile performance were decreased about 3% to 11%. Although there were significant difference of level fatigue, the average scores are below 1 (score 0-7). This result indicates that the fatigue of controllers  are very low.  Although maybe is not really necessary to redesign shift work system, but working hours on each shift still need to be concerned. </em></p>
