Human Life Scientific Study on Construction of Local Life System Aiming at Self-support of the elderly-From the View Point of Environmental Adaptability

我们的三个教师小组进行了为期四年的关于当地老年人独立支持系统的研究。在食品和营养领域，他们研究建立一个方便的模型来研究宿主防御衰老和食物和营养的影响。将一种小型土壤线虫秀丽隐杆线虫（Caenorhabditis elegans）在正常食物来源的大肠杆菌OP50 （Escherichia coli, OP50）草坪上孵化，培养3天，随后喂食乳酸菌（LAB）。饲喂乳酸菌的线虫寿命显著长于饲喂OP50的线虫。在住房和环境设计领域，他们研究了日本健康老年人的最大自愿收缩（MVC）与当前运动之间的关系。上肢关节为肩关节和肘关节，下肢关节为膝关节和小腿关节。这些关节的MVC通过矢状面等距“make”测试测量，并通过Fisher's PLSD方差分析来确定当前运动是否存在的依赖性。对MVC与运动之间关系的分析显示，在男性和女性受试者之间，无论是否进行上肢MVC运动，均存在显著差异。在福利研究组中，他们研究了考虑自我导向适应环境变化的机制。为此，他们进行了为期三年的跟踪研究。他们研究了一个人如何影响环境，形成一个新的自己的生活体系，以及他内心经历了什么样的感受变化。结果发现，个体对环境变化的自我导向适应受到自身存在的不稳定性和自我改变必要性意识的影响。

Three groups of our faculty members conducted studies on the local support system for independence of the elderly for four years. In the Food and Nutrition field, they studied to develop a convenient model to investigate senescence of host defenses and the influence of food and nutrition. A small soil nematode, Caenorhabditis elegans, was grown for 3 days from hatching on a lawn of the normal food-derived bacterium Escherichia coli OP50 (OP50), and subsequently the nematodes were fed lactic acid bacteria (LAB). The lifespan of worms fed LAB was significantly longer than that of those fed OP50. In the Housing and Environmental Design field, they studied to investigate the relationship between maximum voluntary contraction(MVC) and current exercise in the healthy Japanese elderly. The joints of the upper limbs investigated were the shoulder and elbow and those of the lower limbs were the knee and leg joint. The MVC of these joints were measured by isometric "make" tests in the sagittal plane, and was analyzed by ANOVA with Fisher's PLSD to determine dependence on the presence or absence of current exercises. The analysis of the relationship between MVC and exercise revealed a significant difference between the subjects, both male and female, with or without current exercise concerning MVC of the upper limbs. In the welfare research group, they studied to consider the mechanism of the self-directive adaptation to the change of environment. For that purpose, they carried out a three-year follow-up research. They researched how a person had influenced environment toward forming a new own system for life, and what change of feelings he had experienced inside. As a result, they found that the self-directive adaptation to the change of environment was influenced by the instability of his being and the awareness of the necessity for changing himself.
