A self-adaptive system is able to adjust its behavior in response to its perception of the environment. One challenging issue for a self-adaptive system is to deal with its variability. The self-adaptive system should manage their diverse functionalities and behaviors and select one of them depending on the encountered environments. To handle this(More)
Agent-based modeling and simulation is a useful method to analyze and predict the complex and dynamic behavior of a smart grid which consists of diverse stakeholders and components such as devices, services and policies. A smart grid adaptively behaves in its dynamically changed environment and evolves over time as introducing new components and modifying(More)
—A self-adaptive system reacts to the changing environment by modifying its functionality in relation to the encountered state of the environment. In order to adapt to a new situation, such system goes through many decision points during the adaptation process. Knowledge forms the basis of decision making within the adaptation process. There are already(More)

[Subjects] Twenty elderly people were divided into the horseback riding exercise and control group (n = 10 each). [Methods] The exercise was performed for 15 minutes, 3 times per week(More)
[Purpose] The purpose of this study was to determine how an exercise program focusing on muscular strength could aid firefighters with chronic lower back pain. [Subjects] The research subjects were randomly assigned to two groups, the experimental group (n=8) and the control (n=8). [Methods] The experimental group performed two types of exercise programs(More)
[Purpose] The aim of this study was to examine the effects of exercise therapy on blood lipids of obese women. [Subjects] The subjects were 24 clinically obese women. [Methods] The subjects were divided into an exercise group (n=12), and a control group (n=12). The exercise group performed exercise for 10 weeks with diet restriction. We investigated how(More)
[Purpose] The aim of this study was to investigate the effect of an exercise intervention on the balance ability and muscle function of elderly women. [Subjects] The subjects were randomly divided into a control group (n=10) and an exercise group (n=10). [Methods] The subjects participated in an elastic band exercise program lasting for 8 weeks, exercising(More)
