项目摘要

Low birthrate and long life expectancy among the Japanese population have made it imperative to assess quality of life (QOL) and to promote health in geriatric care. To achieve these important goals, the present study investigated the following three items. (1) The development of a measurement system-additional to monitoring of vital signs by such methods as standard electrocardiography (ECG) and pulse oximetry-that is non-restraining and enables prolonged measurement of ECG components and of phonation, which indicates the wellbeing of the individual. (2) The development of a long-term measurement and evaluation system of oral functions such as articulation and swallowing. (3) The establishment of an e-healthcare system using this measurement system to assess QOL, relieve stress, and promote health. The present research succeeded in developing non-restraining monitoring technology that does not interfere with the participant's daily activities, which consists of a neckband (ECG R wave measuring device) and an amplifier This neckband-type ECG monitoring system has the advantage of being able to monitor ECG R waves while being attached only to the neck. Moreover we developed a hands-free system that monitors throat sounds such as phonation and swallowing sounds by affixing a throat microphone to the skin of the neck. The data collected showed the number of times a participant laughed and the amount of time spent talking in one day. Furthermore, an experiment regarding the relationship between laughter and stress was then conducted. The results indicated that bursts of laughter are effective fur relieving stress. Specifically, the effects of the frequency and duration of laughter on stress reduction were clarified for the first time, clearly indicating the importance of e-healthcare system.

日本人口的低出生率和长寿命使得评估生活质量(QOL)和促进老年保健健康成为当务之急。为了实现这些重要目标，本研究调查了以下三个方面。(1)开发一种测量系统--除了通过标准心电图法和脉搏血氧仪等方法监测生命体征之外--该系统是无限制的，能够长期测量心电成分和发声，这表明个人的健康状况。(2)建立发音、吞咽等口腔功能的长期测量和评价系统。(3)建立使用该测量系统评估生活质量、缓解压力、促进健康的电子医疗系统。本研究成功地开发了一种不干扰受试者日常活动的无限制监测技术，该技术由一个颈带(心电R波测量仪)和一个放大器组成。这种颈带式心电监测系统的优点是可以监测到心电R波，而只连接在脖子上。此外，我们开发了一种免提系统，通过将喉咙麦克风固定在脖子的皮肤上来监测喉咙的声音，如发音和吞咽声音。收集的数据显示了参与者在一天中笑的次数和交谈的时间。此外，还进行了一项关于笑和压力之间的关系的实验。结果表明，爆笑是一种有效的缓解压力的方法。具体地说，首次阐明了笑的频率和持续时间对减压的影响，明确表明了电子医疗系统的重要性。
