Background/Aims: The aim of this study is to compare body composition, metabolic status and lung function among older patients. Methods: A health-screening program of 2,085 participants aged >60 years was conducted at the Health Promotion Center in Seoul St. Mary’s Hospital between January 2012 and December 2014. Subjects were classified in the following age categories: 60s, 70s and 80s. Anthropometrics, biochemical factors, and lung function by spirometry were evaluated in each group. Bioelectrical impedance analysis was used to assess the body composition. Results: Mean age in each group was as follows; 60s (63.6±2.8 years), 70s (73.3±2.7 years) and 80s (82.3±2.3 years). Males were predominant in all age groups. Skeletal muscle mass was significantly highest in the 60s, meanwhile body fat (%) and waist circumference was significantly highest in the 80s. Underlying conditions such as hypertension, diabetes and metabolic syndrome was seen mostly in the 80s. FVC (% Pred) and FEV1/FVC ratio was also significantly lowest in the 80s. Conclusions: The age-related increase in body fat, decrease in muscle mass and decreased lung function was observed.

The COVID19 pandemic has presented new and incredible challenges for millions of workers around the globe. Last 12 months, the workforce at large has quickly and strategically navigated the sudden shift to remote working while maintaining the symbolic relationship between business continuity and employee well-being. This study was launched to investigate the current shift of the office environment, specially for back-to-the office, analyzed the design strategies suggested by office planning and design practices, Five major tasks in the design strategies for back-to-the-office was found, such as physical distancing and optimal density, communication physically and psychologically, hygiene and cleaning, health and wellness, and space flexibility and multi-functionality. 20 design practices which were designed for back-to-the offices after COVID19, were selected to investigate how those five tasks were concerned in design solutions. Physical distancing and optimal density were mostly applicated through the design practices overall, with distancing between workstations, one-way circulation, screening and monitoring protocols. Other four tasks were also applied in various ways to support the back-to-the office strategies. By the research, those five tasks were highly interacted and accelerate to improve the safety and health quality of the office. This study was to help the firms and designers who not ready for a new shift, to rethink their office spaces through both forward-looking and simple way to protect their office and employees from the current and future pathogens and help them feel safe coming back to the office. More studies should be expanded to explore the new materials and policies for advanced standards of space elements including surfaces and finishes.
