- Demographic changes can be observed all over the world. The number of seniors located in the societies of well-developed countries continues to rise. Both enterprises and governments need to be prepared for such changes. Consequently, public spaces need to evolve to reduce problems related to ageism and be friendly to all. Much attention is currently being paid to finding solutions for redesigning public spaces and adjusting them to the needs and requirements of senior citizens. To identify the preferences of seniors in relation to the characteristics of furniture in indoor public spaces, a survey study with 1539 respondents aged 60+ was conducted in Denmark, Finland, Latvia, Poland, Russia and Sweden. The gathered data were coded and implemented to the unified database. The statistical grouping method was used to recognize the characteristics of the needs and attitudes of seniors related to the use of public space furniture. The main variables taken into consideration in the analysis were the age and gender of respondents and their country of living. Among the most important findings are those indicating the necessity to provide the increased number of furniture for sitting in the public spaces and making sure they are not located too far away from each other. As the main disadvantages of public space furniture respondents indicated the lack of armrests or other solutions to facilitate getting up and/or sitting down, as well as profiled backrests that constitute solid support for the spine. The implementation of these data in the process of rethinking and redesigning public spaces may support the adaptation of indoor public furniture according to the requirements of a very large group of customers, namely, seniors.

- Background:Understanding the protective potential of operating room (OR) ventilation under different conditions is crucial to optimizing the surgical environment. This study investigated the air quality, expressed as colony-forming units (CFU)/m³, during orthopedic trauma surgery in a displacementventilated OR; explored how traffic flow and the number of persons present in the OR affects the air contamination rate in the vicinity of surgical wounds; and identified reasons for door openings in the OR.Methods:Data collection, consisting of active air sampling and observations, was performed during 30 orthopedic procedures.Results:In 52 of the 91 air samples collected (57%), the CFU/m³ values exceeded the recommended level of <10 CFU/m³. In addition, the data showed a strongly positive correlation between the total CFU/m³ per operation and total traffic flow per operation (r=0.74;P=.001; n=24), after controlling for duration of surgery. A weaker, yet still positive correlation between CFU/m³ and the number of persons present in the OR (r=0.22;P=.04; n=82) was also found. Traffic flow, number of persons present, and duration of surgery explained 68% of the variance in total CFU/m³ (P=.001).Conclusions:Traffic flow has a strong negative impact on the OR environment. The results of this study support interventions aimed at preventing surgical site infections by reducing traffic flow in the OR.

- Background: Operating theatres (OTs) are valuable and costly resources that need to be appropriately designed and stocked for efficient, quality and safe patient care. We assessed the logistic inefficiency including the availability and location layout of necessary supplies across OTs of a high-volume tertiary-care academic medical center. Methods: A blinded observer (anesthesia technologist) was allocated to 10 OTs. For each OT, the availability, quantity and time spent to locate and obtain a set of required items were recorded (baseline values). We then developed an OT mapping plan to determine the specific item/s to be stocked in specific locations, and one OT was standardized to this configuration map. A blinded observer was then allocated to this standardized OT and time spent to obtain the same set of items was again recorded. Six of our regular OTs were then standardized to the same configuration, and the time to obtain the items by a blinded observer were again recorded for each OT. T tests compared the time required to locate items in the standardized OT vs. regular OTs; paired t tests compared the time required in each OT vs. itself before and after standardization. Results: The observer required significantly more time in each of the 10 regular OTs compared to the standardized OT. The time spent by the observer to obtain the required items significantly and considerably decreased in each of 6 OTs after their standardization, compared to the time required before their standardization. Conclusion: This quality improvement project successfully reduced the time required to identify and locate different supplies, which impacts on the efficiency and quality of patient care. For anesthesia staff moving from one anesthetizing location to another within the institution, consistencies in location and number of anesthesia equipment and supplies create higher levels of safety and professionalism.

- The digitalization of society brings many opportunities and challenges, especially on how we organize the welfare society in the future. This becomes especially pertinent as we are heading toward a global increase of older people, which will strain healthcare and bring the challenge of building sustainable solutions. In this paper, we argue that the unsustainable solutions within healthcare are due to them being defined and ‘solved’ with a single approach or approaches used in silos. We advocate that a more sustainable solution could be achieved by combining systems thinking and design thinking perspectives throughout the entire process—from problem definition to solution offering. A benefit of such combined perspectives is the ability to develop a shared context among all stakeholders, which helps uncover unique tacit knowledge from their experience. This will serve as a solid foundation to generate unconventional ideas that will lead to sustainable and satisfactory solutions.

The Contribution of Ski Poles to Aerodynamic Drag in Alpine Skiing
- 2023

Ingår i: Applied Sciences. - : MDPI. - 2076-3417. ; 13:14

Tidskriftsartikel (refereegranskat)abstract
- The present study was designed to determine the contribution of the cross-sectional area of the ski poles (Sp) to the total aerodynamic drag during alpine skiing. At three different wind speeds in a wind tunnel, 10 skiers assumed typical alpine skiing postures (high, middle, and tuck), and their frontal aerodynamic drag was assessed with a force plate and their cross-sectional area, along with that of their ski poles, determined by interactive image segmentation. The data collected were utilized to examine intra-subject variation in Sp, the effects of Sp on the coefficient of aerodynamic drag (Cd), and the product of Cd and total cross-sectional area (Cd∙S. The major findings were as follows: (i) Sp ranged from 0.0067 (tuck position) to 0.0262 m2 (middle position), contributing 2.2–4.8% of the total cross-sectional area, respectively; (ii) Sp was dependent on wind speed in the high and middle positions; (iii) intra-subject variations ranged from 0.0018 m2 (27.6%) in the tuck position to 0.0072 m2 (30.5%) in the high position; (iv) Sp exerted a likely effect on Cd and Cd∙S. The extensive intra- and inter-skier variability in Sp can account for as much as ~5% of the total frontal cross-sectional area and future investigations on how elite skiers optimize their positioning of the poles in a manner that reduces aerodynamic drag are warranted.
