This study was conducted to draw prioritized indicators which are applicable to decide priority order in the assessment process of budget allocation for the healthcare R&D project. We set up the hierarchy based on the review of previous researches and the prioritized assessment indicators, and conducted a survey to experts in Healthcare-related government agencies, academia, research and industry. The results are derived, using the method of Analytic Hierarchy Process (AHP). When no specific research type is suggested, “Necessity of the research” is chosen with the highest proportion (57.0%). In the case of basic research and policy research, “importance of policy direction” is highly chosen (51.2%) with the response of “Necessity of the research” (61.7%). However, “Economic feasibility” is critically recognized (51.5%) in case of the high technology research, indicating that the response to expected effect may be different depending on research type.

To design the cockpit of Korean helicopter, anthropometric data for Korean helicopter pilots as a target population is necessary. The present study measured the body sizes of Korean helicopter pilots to design the cockpit of Korean helicopter, and compared the measurements with those of Korean civilian and the US Army. The sample size was 100 which determined by a statistical analysis. Anthropometric measurements were collected for 100 samples (male=94, female=6; age group=20~40) of Korean helicopter pilots by applying standard measurement protocol. To compare three anthropometric data, Korean civilian and US Army data were controlled by considering age group (20~40) and gender ratio (male: female=9:1) of Korean helicopter pilots. The average body sizes of Korean helicopter pilots were mostly similar to those of Korean civilian, however, lower limb related variables (hip breadth, popliteal height and thigh clearance) and shoulder-to-elbow length were significantly greater (1~7%) at a=0.05. Furthermore, the average body sizes for Korean helicopter pilots regarding lower limb length and thickness were significantly smaller than those of the US Army (1~12%); however, the average body sizes for Korean helicopter pilots regarding upper body related variables (sitting height, sitting eye height, and acromial height) and hip breadth were significantly greater (0.7~1.9%). Lastly, size variability for Korean helicopter pilots was significantly smaller than those of Korean civilian and the US Army. Anthropometric data for Korean helicopter pilots of the present study was applied to design and evaluate a Korean helicopter cockpit.

<P><B>Abstract</B></P> <P>A revised pilot oxygen mask design was developed for better fit to the Korean Air Force pilots’ faces. The present study compared an existing pilot oxygen mask and a prototype of the revised mask design with 88 Korean Air Force pilots in terms of subjective discomfort, facial contact pressure, and slip distance on the face in high gravity. The average discomfort levels, facial contact pressures, and slip distance of the revised mask were reduced by 33%–56%, 11%–33%, and 24%, respectively, compared to those of the existing oxygen mask. The mask evaluation method employed in the study can be applied to ergonomic evaluation of full- or half-face mask designs.</P> <P><B>Highlights</B></P> <P> <UL> <LI> An ergonomic protocol for pilot oxygen mask was developed to evaluate a pilot oxygen mask design. </LI> <LI> The discomfort, contact pressure, and slip distance of a mask on the face in high G were evaluated. </LI> <LI> A revised pilot oxygen mask was compared to the existing oxygen mask with Korea Air Force pilots. </LI> <LI> The usability of the revised mask design was found superior to that of the existing mask design. </LI> </UL> </P>

Objective: The present study is intented to evaluate a safety-shoe with a ventilation hole in terms of inside-shoe microclimate and wearing comfort. Background: Safety shoes have functions to protect a worker’s feet and provide proper fitness and thermal comfort. However, the workers are wearing safety shoes for more than 6 hours a day, so that the safety shoes are exposed to the problems of skin disease such as athlete’s foot. Method: Ergonomic tests were conducted with safety-shoe wearers in industry to compare with ventilation hole shoes with the patented ventilation system to without ventilation shoes without a ventilation system in terms of skin temperature, microclimate(temperature, humidity), local sweat rate, thermography and subjective comfort. Results: The skin temperature measured at the navicular bone was found less increased in with ventilation hole shoes than in without ventilation shoes on average by 0.1℃ during the rest period and 0.5℃ during the exercise and recovery periods. The inside-shoe temperature measured at the toe region was found less increased in with ventilation hole shoes than in without ventilation shoes on average by 0.6℃ during the rest period and 0.3℃ during the exercise period. The inside-shoe humidity measured at the toe region was found less increased in with ventilation hole shoes than in without ventilation shoes on average by 15.1% during the rest period, 11.1% during the exercise period, and 15.2% during the recovery period. The amount of sweat measured on the foot at the end of the experiment was found significantly less in with ventilation hole shoes than in without ventilation shoes on average by 34%. Conclusion: The present study found that the safety shoes with ventilation system were superior than general safety shoes by decreasing skin temperature, inside shoe temperature, and relative humidity and by increasing thermal comfort. Application: The air ventilation system of the safety shoes can be applicable to military boots or golf shoes to increase their thermal comfort.

Objective: The aim of this study is to develop a new sizing system of the oxygen masks for Korean pilots. Background: It is important for Korean pilots to design an oxygen mask reflecting facial anthropometric data of Korean pilots to improve wearing comfort, oxygen supply effectiveness, and safety. Method: The faces of 276 Korean pilots were measured. The existing sizing system of the oxygen mask was analyzed in terms of key dimensions (face length, lip breadth) and the present wearing condition. Results: To select an optimal sizing system of the oxygen masks, 3 sizing systems generated by grid method, clustering method, and optimization method were compared in terms of accommodation percentage, number of sizes, and usage convenience. As a result, the sizing system generated by grid method was determined as an optimal sizing system for Korean pilots. Finally, size separation criteria of the new sizing system were adjusted for usage convenience (6 sizes, accommodation percentage: 96.4%). Conclusion: We developed the new sizing system of the oxygen masks reflecting characteristics of Korean pilots. Application: The new sizing system would be applied to Korea Air Force after a validation through a usability test.

World Health Organization Integrated Care for Older People (ICOPE) and the Integrated Care of Older Patients with Frailty in Primary Care (ICOOP_Frail) Study in Korea

The World Health Organization (WHO) recently endorsed the proposal for a Decade of Healthy Ageing (2020–2030). The WHO defines “healthy aging” as “the process of developing and maintaining the functional ability that enables wellbeing in older age.” Among the strategies for the Decade of Healthy Ageing, the WHO has suggested enhancing intrinsic capacity, promoting functional ability, and implementing the Integrated Care for Older People (ICOPE) package. The WHO has defined steps for ICOPE evaluation and scale-up and is performing a prospective study in 2–3 countries (low and middle income, high income) to test its feasibility in 2021–2022 and a multinational randomized study to validate its clinical efficacy and effectiveness in 2022–2024. Intrinsic capacity and frailty represent two faces of the same coin, with one indicating the reserves of the individual and the other indicating the deficits that accumulate with age. The Integrated Care of Older Patients with Frailty in Primary Care (ICOOP_Frail) study is the first integrated care program for frailty or functional decline in primary care in Korea. The results suggest that the ICOOP_Frail study can be utilized as a reference for ICOPE studies in Korea or at least to provide important findings for the forthcoming ICOPE implementation study in Korea.
