The exposure to extreme temperatures in workplaces involves physical hazards for workers. A poorly acclimated worker may have lower performance and vigilance and therefore may be more exposed to accidents and injuries. Due to the incompatibility of the existing standards implemented in some workplaces and the lack of thermoregulation in many types of protective equipment that are commonly fabricated using various types of polymeric materials, thermal stress remains one of the most frequent physical hazards in many work sectors. However, many of these problems can be overcome with the use of smart textile technologies that enable intelligent thermoregulation in personal protective equipment. Being based on conductive and functional polymeric materials, smart textiles can detect many external stimuli and react to them. Interconnected sensors and actuators that interact and react to existing risks can provide the wearer with increased safety, protection, and comfort. Thus, the skills of smart protective equipment can contribute to the reduction of errors and the number and severity of accidents in the workplace and thus promote improved performance, efficiency, and productivity. This review provides an overview and opinions of authors on the current state of knowledge on these types of technologies by reviewing and discussing the state of the art of commercially available systems and the advances made in previous research works.

Abstract Natural biological systems are constantly developing efficient mechanisms to counter adverse effects of increasing human population and depleting energy resources. Their intelligent mechanisms are characterized by the ability to detect changes in the environment, store and evaluate information, and respond to external stimuli. Bio-inspired replication into man-made functional materials guarantees enhancement of characteristics and performance. Specifically, butterfly architectures have inspired the fabrication of sensor and energy materials by replicating their unique micro/nanostructures, light-trapping mechanisms and selective responses to external stimuli. These bio-inspired sensor and energy materials have shown improved performance in harnessing renewable energy, environmental remediation and health monitoring. Therefore, this review highlights recent progress reported on the classification of butterfly wing scale architectures and explores several bio-inspired sensor and energy applications.

Abstract: Dentists are at risk of experiencing a number of occupational hazards including physical hazards. Potential physical hazards include noise, lighting, ionizing and non-ionizing radiation, percutaneous exposure incident (PEI), and extreme temperatures. Efforts to control physical hazards based on the hierarchy of hazard control in the work of dentists are substitution, engineering, administration, and the use of personal protective equipment (PPE).Keywords: physical hazards, hazard control hierarchy Abstrak: Dokter gigi merupakan salah satu profesi yang berisiko mengalami sejumlah bahaya akibat pekerjaan, termasuk bahaya fisik.

Recent Trends

The coronavirus SARS-CoV-2 pandemic has affected over one hundred million people worldwide and has resulted in over two million deaths. In addition to the toll that coronavirus takes on the health of humans infected with the virus and the potential long term effects of infection, the repercussions of the pandemic on the economy as well as on the healthcare system have been enormous. The global supply of equipment necessary for dealing with the pandemic experienced extreme stress as healthcare systems around the world attempted to acquire personal protective equipment for their workers and medical devices for treating COVID-19. This review describes how 3D printing is currently being used in life saving surgeries such as heart and lung surgery and how 3D printing can address some of the worldwide shortage of personal protective equipment, by examining recent trends of the use of 3D printing and how these technologies can be applied during and after the pandemic. We review the use of 3D printed models for treating the long term effects of COVID-19. We then focus on methods for generating face shields and different types of respirators. We conclude with areas for future investigation and application of 3D printing technology.

The article is devoted to the investigation of the current state of legal regulation of provision of agricultural workers with personal protective equipment, analysis of legislative novelties and highlighting the main disadvantages in this area with the formulation of proposals for their elimination. It is defined that the legal framework for provision of workers of agricultural enterprises with personal protective equipment (hereinafter - PPE) is currently being updated, primarily due to Ukraine’s international and European integration obligations to adapt domestic legislation in this area to international requirements. It is proved that the main positive innovations are: the introduction of a combination of the mandatory minimum provision of workers by PPE with the possibility for the employer to decide on the provision of workers by PPE overtime; giving priority to means of collective protection over PPE; specification of the rights of workers to participate in resolving issues related to the their provision of PPE; regulation of the procedure for selecting PPE by the worker in excess of the established minimum norms. A number of measures are proposed to promote the practical implementation of the provisions of the Minimum Safety and Health Requirements for the use of personal protective equipment in the workplace: development of recommendations for employers to assess occupational risks in the workplace; provision of advisory services in the field of risk assessment at workplaces and on the selection of PPE above the established norms (such services may be provided by the State Labor Service of Ukraine); provision of workplace risk assessment services by the State Labor Service or other entities (this is especially relevant for small agricultural enterprises). A proposal was made to introduce incentives for employers to provide employees (including agricultural enterprises) with PPE by establishing the dependence of the amount of contributions for compulsory state insurance against accidents at work and occupational diseases on the level of occupational injuries / diseases at the enterprise.

The Impact

Abstract Introduction Preparations of health systems to accommodate large number of severely ill COVID-19 patients in March/April 2020 has a significant impact on nuclear medicine departments. Materials and Methods A web-based questionnaire was designed to differentiate the impact of the pandemic on inpatient and outpatient nuclear medicine operations and on public versus private health systems, respectively. Questions were addressing the following issues: impact on nuclear medicine diagnostics and therapy, use of recommendations, personal protective equipment, and organizational adaptations. The survey was available for 6 days and closed on April 20, 2020. Results 113 complete responses were recorded. Nearly all participants (97 %) report a decline of nuclear medicine diagnostic procedures. The mean reduction in the last three weeks for PET/CT, scintigraphies of bone, myocardium, lung thyroid, sentinel lymph-node are –14.4 %, –47.2 %, –47.5 %, –40.7 %, –58.4 %, and –25.2 % respectively. Furthermore, 76 % of the participants report a reduction in therapies especially for benign thyroid disease (-41.8 %) and radiosynoviorthesis (–53.8 %) while tumor therapies remained mainly stable. 48 % of the participants report a shortage of personal protective equipment. Conclusions Nuclear medicine services are notably reduced 3 weeks after the SARS-CoV-2 pandemic reached Germany, Austria and Switzerland on a large scale. We must be aware that the current crisis will also have a significant economic impact on the healthcare system. As the survey cannot adapt to daily dynamic changes in priorities, it serves as a first snapshot requiring follow-up studies and comparisons with other countries and regions.
