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 face-to-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)
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)
Super micro surgery in neurosurgical field is very challenging problem because neurosurgeons handle very tiny object through a microscope. Advances in technology such as microscope make micro surgery possible, but manipulating small instruments under the circumstance of microscope restricts the humans' dexterity even in the constrained workspace. To perform(More)
This study presents automated methods for predicting valence and quantifying valenced thoughts of a text. First, it examines whether Wordscores, developed by Laver, Benoit, and Garry (2003), can be adapted to reliably predict the valence of open-ended responses in a survey about bioethical issues in genetics research, and then tests a complementary and(More)
Forceps tracking is an important element of high-level surgical assistance such as visual servoing and surgical motion analysis. In many computer vision algorithms, artificial markers are used to enable robust tracking; however, markerless tracking methods are more appropriate in surgical applications due to their sterilizability. This paper describes a(More)
In this paper, we introduce a new platform for integrated development of visual surveillance algorithms, named as PIL-EYE system. In our system, any functional modules and algorithms can be added or removed, not affecting other modules. Also, functional flow can be designed by simply scheduling the order of modules. Algorithm optimization becomes easy by(More)
