PurposeThe purpose of this study was to propose and test a conceptual model that explains the interrelationships among perceived social support, loneliness, physical activity (PA), and quality of life (QoL) among active older adults in South Korea.MethodsData were collected from 332 individuals over the age of 65 using a systematic stratified convenience sampling method. Survey data were collected and analyzed using a structural equation model (SEM).ResultsPerceived social support had a significantly positive effect on PA (β = 0.14, p < 0.01) and QoL (β = 0.28, p < 0.001) while decreasing loneliness (β = −0.55, p < 0.001). PA had a significant positive effect on QoL (β = 0.12, p < 0.01), and loneliness had a negative effect on QoL (β = −0.37, p < 0.001). Loneliness mediated the relationship between perceived social support and QoL.ConclusionThe SEM results of the current study support the proposed model that explained the interrelationships among perceived social support, loneliness, PA, and QoL among active older adults in South Korea. These findings suggest the importance of incorporating social support mechanisms for PA interventions in order to enhance QoL. The findings of this study can help create more effective health and physical education programs for the older generations in South Korea to enhance their QoL.

Humor is an important option for employees responding to frustrating circumstances because humorous responses can be less confrontational than alternative ways of expressing dissatisfaction. The present study examined how student interns enacted humor as a response to workplace dissatisfaction. Results indicated a continuum of humorous messages and a variety of goals motivating those messages. These findings demonstrate the nuances in humor as a way of communicating dissatisfaction while also underscoring the need to further understand how goals and outcomes are related as employees dissent. At a deeper level, these results speak to issues of power and identity as low-positioned, contingent employees used humor to recast their identities apart from their status and to negotiate the boundaries of acceptable communication.

Objective: By the year 2100, the Earth's mean temperature could increase 1.8°C to 4.0°C, in part due to the release of greenhouse gases (GHGs). This increase may negatively influence personal health, directly through GHG emissions and increased temperature, and indirectly through climate change's impact on the environment. The potential effect of climate change on physical activity (PA), and in turn, obesity, is less clearly understood. Methods: We carried out an integrative review of English-language peer-reviewed published papers to improve understanding of how climate change may influence PA and obesity. Results: From an initial retrieval of 4587 papers, we condensed the search to 19 using a PRISMA approach. Eight papers reported individual physiological responses to excessive heat during PA, primarily among elderly persons, with 11 others providing broad implications for PA trends over time in conjunction with climate change. Conclusion: Overall, excessive heat exposure during PA has greater impact on the elderly whose bodies are less able to thermoregulate core temperature, placing increased strain on cardiovascular and respiratory systems. Because elderly individuals report more cardiovascular and respiratory illnesses than the overall population, climate change may exacerbate these conditions during PA. Rising temperature may decrease PA prevalence, especially during summer, thereby increasing sedentariness. Rising temperature could decrease PA frequency and intensity, and concomitantly, place already vulnerable populations in life-threatening situations.
