Summary: This study examined the effects of wearing a water-soaked inner t-shirt with a ventilation garment on thermal and cardiovascular strain in young and older individuals during moderate-intensity work in a hot environment. The results showed that wearing a water-soaked inner t-shirt significantly reduced rectal temperature, heart rate, and whole-body sweat loss compared to wearing a dry t-shirt. This suggests that this cooling strategy is effective and practical for mitigating heat and cardiovascular strain.

Summary: This study investigated the association between physiological and perceptual heat strain in individuals wearing stab-resistant body armor (SRBA). Trials conducted in warm and hot environments revealed that the perceptual strain index (PeSI) showed a moderate association with the physiological strain index (PSI), and could predict low and high levels of physiological strain with moderate accuracy. The results suggest that subjective responses can be used as an indicator for predicting physiological strain while wearing SRBA, providing important knowledge for the usage and development of SRBA and physiological heat strain assessment.

Summary: The purpose of this study was to investigate heat strain while wearing pesticide protective clothing (PPC) with different physical properties in hot environments. The results showed that under 80% relative humidity conditions, physiological variables and subjective perceptions were greater than under 50% relative humidity conditions. Compared to polyester/cotton work clothing, the commonly used nylon suit had a greater physiological burden, and there were no statistical differences between the Tyvek and nylon suit conditions, especially in the 80% relative humidity environment. During exercise, there were no differences in humidity sensation among the PPC conditions, but during recovery, subjects felt more humid in the Tyvek or nylon suit than in the polyester/cotton work clothing.

Summary: The study found that wearing stab-resistant body armor during a 50-minute treadmill walk in a hot environment had minimal impact on core temperature, skin temperature, heart rate, oxygen consumption, sweat loss, and psychophysical responses. Although there were slight differences in temperature and sweating efficiency, overall, the armor did not significantly affect the physiological and psychophysical strain of the security guards in this scenario.

Summary: In this study, the effects of repeated work bouts in the heat on peak body core temperature were investigated, along with exploring sex-based differences in body core temperature responses. The research found that body core temperature elevation over time was faster in the initial work bouts, with females showing significantly lower body core temperature elevation compared to males during the trial. Additionally, a gradual reduction in heat storage in subsequent exercise bouts prevented a cumulative increase in heat strain.

Summary: This study explores a transmission scheme for free-floating motes based on infrared, which reduces wireless data rate and system power consumption through pulse-interval modulation (PIM) communication. The results show that PIM has strong neural information transmission capability and matches the performance of traditional wired systems in real-time closed-loop BMI tests. Additionally, the PIM communication scheme is feasible in terms of power and enables high-channel-count high-performance BMIs.

Summary: The role of peripheral biomarkers in executive performance following acute aerobic and resistance exercise was explored in this study. The findings suggest that these biomarkers do not directly contribute to the reduction in reaction time following exercise, but a greater increase in noradrenaline may be associated with a decrease in accuracy after acute resistance exercise.

Summary: This paper presents a methodology for mapping and prioritizing research and innovation needs in a multi-disciplinary field. The methodology is applied to the field of Arctic maritime safety and security to guide a European Union funded research project. The methodology involves creating a hierarchy of needs through stakeholder workshops, literature review, and questionnaires, and then seeking stakeholder opinion to determine the importance and challenge level of each sub-need. A goal programming knapsack model is used to select priority needs based on overall importance, balance between topics, and balance between long-term research and short-term implementation needs.

Summary: When exposed to uncomfortable ambient temperatures, human behavioral responses are more effective than autonomic responses at regulating body temperature. These behavioral responses are influenced by an individual's perception of the thermal environment, which includes visual information. This review analyzes existing literature on the impact of visual environment manipulation on thermal perception, identifying frameworks, research rationales, and potential mechanisms. Out of 31 included experiments with 1392 participants, 80% reported a difference in thermal perception after manipulating the visual environment, suggesting the importance of visual cues in thermal perception.

Summary: Whole-body cryotherapy is a non-pharmacological treatment that influences inflammatory events and has various benefits, such as improved sleep quality, faster neuromuscular recovery, and chronic pain relief. It may also have positive effects on mental health and cognitive functions. There have been concerns about its safety, but these concerns are often based on misunderstandings regarding the differences between whole-body cryotherapy and partial-body cryotherapy. This article reviews the literature and concludes that the safety risks associated with whole-body cryotherapy are within acceptable limits and can be prevented by following existing recommendations and guidelines.
