The purpose of this study was to investigate the relationships among leisure motivation, leisure attitude, and health promotion lifestyle. The participants were recruited from a convenience sampling that subjects were at least 55 years of age in Tainan City, Taiwan. Three hundred survey instruments were distributed, and 227 effective instruments were returned, for an effective rate of 75.7%. Th...

It is well known that some XML elements correspond to objects (in the sense of object-orientation) and others do not. The question we consider in this paper is what benefits we can derive from paying attention to such object semantics, particularly for the problem of keyword queries. Keyword queries against XML data have been studied extensively in recent years, with several lowest-common-ances...

This paper presents an attitude control strategy in the three planar space robots having two DOF for docking operation of a free flying hexagonal object using the bond graph technique for modeling and simulation. As the highly non linearity, strongly coupled and non-holonomic characteristics of a free flying space robot, the position and posture of the base body changes when the free floating s...

When a robot arm(s) conducts some tasks on a satellite, the satellite attitude stability is necessary against the robot arm's motion to maintain the communication link and to generate electrical power from the solar panel(s). However the reaction from the robot arm is much stronger than the natural environmental disturbance torque that the traditional satellite attitude control system cares. Na...

Manually assigned keywords provide a valuable means for accessing large document collections. They can serve as a shallow document summary and enable more efficient retrieval and aggregation of information. In this paper we investigate keywords in the context of the Dutch Folktale Database, a large collection of stories including fairy tales, jokes and urban legends. We carry out a quantitative...

We describe how the interaction mode with an Embodied Conversational Agent (ECA) affects the users’ perception of the agent and their behavior during interaction, and propose a method to recognize the social attitude of users towards the agent from their verbal behavior. A corpus of human-ECA dialogues was collected with a Wizard of Oz study in which the input mode of the user moves was varied ...
