Although there has been much speculation regarding the strengths and weaknesses of face-to-face versus online deliberative settings, no studies have systematically compared the two. Drawing on a national sample of Americans who reported deliberating faceto-face and/or online, we examine these two deliberative settings with regard to the participants, the(More)
With the advent of social network sites (SNSs), people can efficiently maintain preexisting social relationships and make online friendships without offline encounters. While such technological features of SNSs hold a variety of potential for individual and collective benefits, some scholars warn that use of SNSs might lead to socially negative(More)
Automated Graphical User Interface (GUI) testing is one of the most widely used techniques to detect faults in mobile applications (apps) and to test functionality and usability. GUI testing exercises behaviors of an application under test (AUT) by executing events on GUIs and checking whether the app behaves correctly. In particular, because Android leads(More)
OBJECTIVES Most methods currently used to assess surgical skill are rather subjective or not adequate for microneurosurgery. Objective and quantitative microneurosurgical skill assessment systems that are capable of accurate measurements are necessary for the further development of microneurosurgery. METHODS Infrared optical motion tracking markers, an(More)
BACKGROUND Microsurgery is a widely performed process in neurosurgery. However, it is difficult for surgeons because manipulating small and long instruments under a microscope often restricts dexterity. Hand tremors are also an issue, as the accuracy required for microsurgery is very high. METHOD A master-slave robotic platform has been developed for(More)
BACKGROUND AND AIMS Little is known about the extent depression adds to the costs of treatment for physical health conditions. This study examined the paths and the extent to which depression in conjunction with a physical health problem is associated with an increase in healthcare expenditures and how that is different between younger and older adults.

This paper presents the design and implementation of a reconfigurable heterogeneous modular architecture for service robots. The proposed architecture has five key concepts which are different from conventional reconfigurable modular service robots; (1) easy and multiple assembly according to requirements of users, (2) hardware resource sharing system with(More)
This paper introduces a multi-dimensional emotional engine which is influenced by personality of robot. It is a novel approach to design an emotional model by comparison with conventional emotional model which used three-dimensional emotional space. It calculates most emotional elements and memorizes them for the next step of calculation of emotion. This(More)
