"Facilitating Large-scale Collective Discussion"

Abstract: Online direct democratic discussions have received much attention and are likely to be one of the next generation methods for open and public citizen forums. Such forums require systematic methodologies that can efficiently achieve consensuses, reasonably integrate ideas, and avoid flaming. We developed an open web-based forum system with facilitator support functions and deployed it for an internet-based town meeting in Nagoya, Japan as a city project led by its mayor. Our system is called COLLAGREE: COLLective/COLLaborative and AGREEment. In COLLAGREE, people can submit their opinions as a chunk of text as in ordinary forums on Facebook or Twitter, and facilitators can submit their own instruction messages to participants. We want discussions that can be adequately led by facilitators so that many people can be persuaded to accept the final decision. In fact, real-world workshops or town meetings among citizens are usually coordinated by a facilitator who coordinates, leads, integrates, classifies, and summarizes discussions to reach good consensuses or alternatives. The main issue is how to support facilitators so that they can manage largescale discussions. COLLAGREE provides support functions for facilitators. For example, using text-based sentiment analysis, our system automatically judges the degree of agreement on one message. Nagoya in Aichi Prefecture has over three million people. After three months of preparation with its city officers, we created an internet-based town meeting about the city's planning. Mayor Kawamura announced this project in newspapers and on TV as one actual town meeting of the Nagoya Next Generation Total City Planning for 2014-2018. Our experiment ran on COLLAGREE system during a twoweek period with nine expert facilitators from the Facilitators Association of Japan. COLLAGREE gathered 266 registered participants, 1,151 opinions, 3,072 visits, and 18,466 views. The total of 1,151 opinions greatly exceeded the 463 opinions obtained by previous real-world town meetings. Our preliminary results demonstrated that COLLAGREE successfully gathered many more opinions than comparable real-world town meetings and people accepted the importance of facilitators.

"Recent Advances in Digital Forgery and Information Forensics"
Chi-Man Pun



 Chi-Man Pun, Ph.D.
University of Macau, China
Address: email: cmpun [AT] umac.mo
Abstract: Along with the development of computer technology and the popularity of software for multimedia information processing, digital forgery is increasingly easily to achieve, which reduces the credibility of the multimedia data such as digital images, videos and audios greatly. Therefore, digital forgery detection and information forensics have been becoming more and more important in recent years. Among the existing kinds of digital forgeries, copy-move forgery is one of the most common ones, which is to paste a copied region of an image into another part of the same image. During the copy and move operation, some image processing methods such as rotation, scaling, blurring, compression, and noise addition are applied to ensure the imperceptibility of the copied region; however, which can increase the difficulties of forgery detection at the same time. In this talk, we will study the recent advances of digital forgery and information forensics techniques and the related detection methods such as copy-move or splicing forgeries, and multimedia data authentication methods.

"Advancement and education in medical ICT"

Abstract: Due to a lack of physicians and the recent gradual increase in the number of medical services provided in clinical settings, the nurturing of paramedical professionals (the term used to describe healthcare providers other than physicians or dentists, such as nurses, medical technologists, pharmacists, dental hygienists, physical therapists, and occupational therapists) is an urgent issue. In such a situation, paramedical professional training schools are required to provide education in a limited amount of time, help students pass the national exam, and contribute to the stable production of human resources (1).
ICT has been rapidly developing, and applied to medical settings. In this study, I report not only the current status of ICT education in our school (2), but also the development of medical English education (3) and education programs necessary for healthcare providers employing ICT-based self-learning software and Personal Digital Assistant.

"Missing Data Imputation with Rough Set"
Gongzhu Hu


 Gongzhu Hu, Ph.D.
Central Michigan University, USA
Address:
email: hu1g [AT] cmich.edu
Abstract: In rough set theory, data is usually stored in an information table with attributes divided into condition attributes and decision attribute. Due to the uncertainty in the data, The data set is represented by formal approximations and "condition to decision" rules can be deducted from the approximations. In this talk, a new approach to the missing data imputation problem is presented. In this approach, attributes are rearranged such that the attribute with missing values becomes the decision attribute so that decision rules deducted can be used to determine the missing values. For this purpose, the notion of optimal logic attribute and optimal attribute logical flow are introduced based on the roughness of rearrangements to explore the logical causal relations between attributes.

"Affective Learning and Pedagogy using Affective Computing"
Yueh-Min Huang


 Yueh-Min Huang, Ph.D.
National Cheng Kung University, Taiwan
Address:

Abstract: How to motivate students to engage in a class is a critical issue in higher education. The pedagogy to motivating students involves complicated process such as that attracting their attention, arousing the interest, and providing contents of appropriate difficulty. Moreover, the pedagogy design should assist students in developing pleasure and joy to optimizing their emotion experience in learning, such as praising students who get great work and encouraging those who feel frustrated. Otherwise, students experiencing high anxiety may compromise or discontinue learning tasks. In other words, the instructional designers should not merely focus the cognitive domain of learning, but should also consider the affective domain of learning, such as adjusted their instructional strategies according student's positive or negative emotion. Affective computing defined as "computing that relates to, arises from, or deliberately influences emotion or other affective phenomena" (R. W. Picard, 1997) have created the possibility of developing technologies to monitor and appropriately respond to human affective states (e.g., moods and emotions). These innovative technologies have recently captured much attention from instructors and researchers because affective computing offers them opportunities to measure students' affective states instantaneously. Compared to the use of questionnaire that hardly realizing how the continuous change was in the emotional state during the learning tasks, the just-in-time measurement of affective computing can provide continuous observation of the emotional state by which complement the questionnaire. However, the challenge of how to explore the effective pedagogies and practices using affective computing to optimizing learning experience is also posed. For example, although various sensors can capture postural, facial, skin-surface, and gestural changes that carry affective information, which sensors are more suitable and practice for the learning environment? In addition, how to design effective pedagogies that can provide personalized affective feedback according to students’ emotional states? To what extent, some advanced measurement tools, such as Electroencephalography (EEG) and eye-tracking device can reveal those states? Those are all challenging issues. This address aims to respond to these questions and to highlight the opportunities and challenges associated with integrating educational pedagogy using affective computing in learning tasks.
