Objectives: The purpose of this study was to review previous clinical studies on underlying mechanisms of sleep-related type-specific pathophysiological symptoms among the Sasang types.Methods and Procedure: We reviewed seven research databases from December 2003 to August 2015 with the keywords Sasang typology, constitution and sleep. The Sasang type-specific sleep-related symptoms were analyzed based on seven categories, including subjective sleep quality, sleep latency, sleep duration, habitual sleep efficiency, sleep disturbances, use of sleep medications and daytime dysfunction.Results: Total of twelve studies were included in the analysis. The Tae-Yang type showed low subjective sleep quality, long sleep latency and frequent awakening, and the So-Yang type showed long sleep latency. The Tae-Eum type presented high subjective sleep quality, short sleep duration, frequent snore, toss and turn during the sleep, and insomnia and low frequency of dream. The So-Eum type showed long sleep latency in male and high frequency of dream. The Eum type combining Tae-Eum and So-Eum types had higher subjective sleep quality, longer sleep duration and higher frequency of dream than the Yang type combining Tae-Yang and So-Yang types.Conclusions: This study reviewed type-specific sleep-related characteristics and discussed possible pathophysiological mechanisms involved. Differences in sleep characteristics among the Sasang types might stem from type-specific temperaments and require further study.

오로지 인간의 동력만을 이용하여 비행하는 것을 목표로 하는 인간동력 항공기에는 다양한 역학적인 도전요소가 다분하다. 엔진과 비교하여 매우 낮은 동력을 사용하는 인간동력 항공기는 중량과 재료, 공력과 구조 분야의 분석 등이 고려되어야 한다. 또한 항공기가 매우 낮은 속도에서 비행하므로 저속비행에서의 공력 특성을 파악하여야 한다. 서울대학교 인간동력 항공기에서는 이러한 요소들을 만족시키기 위하여 기존의 인간동력 항공기의 비교와 더불어 역학적인 분석을 통하여 설계변수들을 계산하고 설계를 제안하였다. 더불어 복합재를 사용하여 실재 인간동력항공기를 제작하는데 필요한 절차에 대하여 논의하였다. Human powered aircraft: the aim is to fly only by human power, features many challenging issues. Contrary to the general aircraft operated by an engine, human powered aircraft, that manoeuvres by lower power, requires additional consideration about weight, material, aerodynamical and structural analysis. Since this aircraft flies at a low speed, low Reynolds number flight will need to be taken into account. In this paper, SNU (Seoul National University) Human Powered Aircraft was designed by comparing it with the existing human power aircrafts, as well as by using theoretical analysis that obtains the design parameters. Also, this paper discuss about the manufacturing process using composite material for real human powered aircraft.
