Effects of Silver-Care-Robot Program on Cognitive Function, Depression, and Activities of Daily Living for Institutionalized Elderly People

PURPOSE The purpose of this study was to identify the effects on cognitive function, depression, and activities of daily living of Silver-Care-Robot Program for institutionalized elders. METHODS This study was a nonequivalent control group pretest-posttest design. The participants were 42 institutionalized elders (17 in the experimental group and 25 in the control group). The Silver-Care-Robot Program was provided as an intervention which was conducted twice a week for 5 weeks. The Silver-Care-Robot Program is an integrated entertainment program to help the mental, emotional, and physical health of elderly people. Pre-test was conducted on the two groups, and, in order to examine the effects of intervention, a post-test was conducted after 5 weeks. RESULTS There were significant differences in cognitive function and ADL (activities of daily living) between two groups after the program. But the difference in depression in the institutionalized elders was not statistically significant between the two groups. CONCLUSION The Silver-Care-Robot Program should be considered as a regular program for cognitive function and activities of daily living for institutionalized elders.

An Executable Service Process Generation System using Web Service and OWL-S

In this paper, we present the efficient method that generates a service process to provide more information using Web service and OWL-S. Also, we control the robot behavior using task script based on XML. Task script describes tasks that maintain list of planned tasks to execute services. The service composition discovers the most suitable service plan, and then creates an executable service process through the executable service process generation system. An executable service process is transmitted to the process execution engine such as BPEL4WS and Task engine. Finally, execution engine execute the service plan that can provide more services for intelligent robot

An Emotion Expression System for the Emotional Robot

In this paper, we presents an emotion expression system for expressing emotion for the emotional robot, which have a plurality of different sensors sense information about internal/external stimuli. In detail, we propose method for processing information that is collected through various sensors in an intelligent robot, a method for determining an emotion, and a method for expressing a corresponding action. Our system can express a specific emotion of the emotional robot in the form recognizable by a user so that an emotional communication between the user and the emotional robot through affective communication. An emotional expression system is comprised of an emotion feature information collector component, an internal status management component, an action determiner component and an action expression component. Our system can be applied to the emotional robot. Also, our system can be used in developing the Cyber character having an emotion or developing the apparatus having an emotion in the ubiquitous environment.

An XML digital signature for Internet e-business applications

At present, many companies doing business-to-business (B2B) e-business on the Internet have suffered difficulties in extending their e-market and in participating in other markets, since it is impossible for their own e-business systems to interoperate with other e-business systems in other e-markets. To resolve the non-interoperability of the e-business applications, e-commerce common framework specifications, such as eCo and ebXML, have been made by e-commerce software vendors and user companies. These specifications have adopted the XML technology to exchange business documents between e-business applications. So, an XML digital signature for XML-based e-business systems is necessary. In this paper, we describe a method to design and implement an XML digital signature that provides integrity of the business documents, authentication of trading partners, and non-repudiation services, which are necessary for e-business. Our XML digital signature has been implemented according to the XML Signature Syntax and Processing specification of the IETF/W3C XML Signature Working Group.

Building an automated engagement recognizer based on video analysis

This paper presents a process to build a classifier in a data-driven way for recognizing engagement of children in a robot-based math quiz game. The process consists of collecting video recordings from HRI experiments; annotating the social signals and engagement states via video analysis; extracting feature vectors from the annotations and training classifiers. We conducted an experiment with 7 participants of

A socially interactive robot using social skills in physical training

This paper presents an elder care robot system for older people. An elder care robot system provides human-robot interaction application and monitoring service. The study was carried out for five weeks in nursing homes, with the participation of 17 residents. We have conducted a t-test to compare the difference between satisfaction and usability evaluation for the residents and the staff.

EMOTION EXPRESSION AND ENVIRONMENT THROUGH AFFECTIVE INTERACTION

In this paper, we identify the effects of robot social skills for enhancing social interaction in a physical training. To that end, we designed a physical training scenario and conducted an experiment with 28 participants using the humanoid robot NAO. As a result, there were significant differences between the control group where social skills were not used, and the experimental group where social skills were used by the robot.

A space identification system and its robot application using wearable devices

In this paper, we propose a socially interactive robot facilitating social skills and identify the effects of robot social skills, to help maintain a natural and sustained interaction between humans and robot in a physical training. To that end, we conducted an experiment with 28 participants using the humanoid robot Nao. As a result, there were significant differences in 7 out of 9 measured categories between the control group where social skills were not used, and the experimental group where social skills were used by the robot. Therefore, social skills including feedback, mutual gaze and social distance should be consider as a positive social cues for physical training.
