En el ámbito sanitario, las fuentes de radiación óptica son ampliamente utilizadas en varias aplicaciones terapéuticas o diagnósticas, en las que se pretende aprovechar las características de la radiación para lograr un efecto clínico sobre la persona. Por otra parte, la radiación óptica en centros sanitarios puede provenir también de algunos equipos electromédicos o maquinaria que utilizan ese tipo de radiación para su función primordial como sería el caso de las lámparas germicidas. En estos sectores se encuentran además varias fuentes de radiación óptica presentes también en otros ámbitos diferentes al sanitario y que no tienen una aplicación médica directa, como las pantallas de visualización de datos o las lámparas de iluminación general.En este póster se identifican las principales fuentes de radiación óptica presentes en el sector sanitario y se presentan los resultados de las mediciones realizadas en el ámbito hospitalario. Además se propone un conjunto de posibles acciones de prevención y corrección a aplicar para controlar los riesgos detectados.

The presentation describes a randomized field intervention study testing the effect of modifying supervisory safety messages communicated during daily conversations with workers on safety climate and performance. Supervisors in the experimental group received two feedback sessions indicating the extent to which they integrated safety and productivity-related issues in daily conversations with their workers. Supervisors in the control group received no feedback. Feedback data were collected from workers who had been asked to report supervisory messages communicated during their most recent conversation. Using a before-after design, questionnaire data collected 8 weeks before and after the 12-week intervention phase revealed significant improvements for safety climate, safety behavior, team work, and (independently measured) safety audit scores for the experimental group. The same variables have remained unchanged for the control group (except for safety behavior). These results are explained by corresponding changes (or lack thereof in the control group) in perceived supervisory messages during the 6-week period between the first and second feedback sessions.

This paper considers the user experience design concerning user interaction in the digital workplace. It explains what constitutes workplace user experience, and what the effects of bad user experience (UX) may be, such as reduced productivity and erosion of user happiness and satisfaction. The emotions in the workplace play an important role. Positive emotions and pleasant experience in the workplace can help employees to reach better performance and prevent fatigue. Negative emotions accumulated at work can decrease the workplace user performance and health. The personalization of workplace UX can influence workplace productivity. Personalization can support employees to reconfigure their workplaces, allowing them to shape their work experience and suit their work process. The companies should tackle such issues by looking at digital workplace through UX lens. There is a need of an approach to support workplace design aimed at meeting and adapting to user expectations and at creation of positive emotions during working on the workplace.
A methodology for measuring and designing digital workplaces oriented to UX improving is presented. Dimensions of workplace user experience including emotional UX and personalized UX are defined. A checklist guiding UX evaluation and design is proposed. Relevant quantitate indices for measuring workplace UX are developed. This methodology allocates and proposes solutions to problems of workplace UX. It generates recommendations for UX design of digital workplaces with the aim to provide points of reference for designers. The lecture presents a case study illustrating the methodology. Research scope is identified. Further research directions are pointed out.

Background. An increasing number of persons with occupational exposure to technogeneous nanoparticles; an absence of the nanomaterials hygiene regulations and safety standards.
Aim. To evaluate potential risk at the workplaces of: 1) the operator of the E-beam device UE-202 for manufacturing of the nanomaterials and nanopowders; 2) the workers involved in the chemical and mechanical synthesis of nanomaterials.
Materials and methods. Samples chemical analysis was carried out by ІСР-АЕС method using spectrometer Optima 2100 DV. Concentration of the nanoparticles in the air of the working zone was measured by the diffusion aerosol spectrometer DAS-2702. Risk was evaluated using a “control banding” tool.
Results. Maximal concentrations of the particles with sizes between 1 and 100 nm exceeded test levels (Benchmark Exposure Limit) on condition of the working of the E-beam device with closed camera. Concentrations of the nanosized nickel, chromium, and zinc exceeded calculated TLV for nanomaterials (‘benchmark levels’ by BSI-PD 6699-2: 2007) even on conditions, when “macrosubstance” concentrations were not exceeded TLV. The order of magnitude of the nanoscale substances concentration in the air of the working zone corresponds to the benchmark levels for nanomaterials.
Limit values were calculated according to toxicological studies in vitro and in vivo for CdS and PbS nanoparticles. They are correspond to the benchmark levels for these nanosized substances and their concentration in the air of the working zone.
Conclusions. Closing of the nanoparticles manufacturing technological process does not always guarantee the safety of the workers. Even irregular operations in the process of the nanomaterials chemical- and mechanosynthesis are characterized with a significant risk to workers. During the evaluation of the risk at the workplaces, where nanotechnologies are used, information about mass concentration of the nanosized substances is more useful than the data about particles number. Using a “control banding” tool for the operator of E-beam device control band 4 was determined, for operators in chemical and mechanical synthesis control band 3 was determined. The risk management measures were proposed.
