Deontic Relevant Logic: A Strong Relevant Logic Approach to Removing Paradoxes from Deontic Logic

In this paper, we propose a strong relevant logic approach to solve the problems of deontic logic paradoxes. Since the paradoxes in deontic logic have the same form as the paradoxes in traditional (weak) relevant logic, which have been rejected by our strong relevant logic, we show that a new family of logic, named deontic relevant logics, can be established by introducing deontic operators and relative axioms and inference rules into strong relevant logics such that those deontic logic paradoxes are rejected by deontic relevant logics.

Computer Ethics Video Clips for University Students in Japan from 2003 until 2013

The explosive growth of computer networking enormously increases security costs in universities. It is necessary to encourage the cooperation of students, faculty, and staff through education and training of information ethics, together with improving management and technologies, and as a consequence, to reduce university costs. We have been producing collections of video clips for information ethics education for university students to be used as teaching materials. New technology, service, custom, and so on accompany new security issues and ethics issues. So we have continued to produce video clips for these issues for ten years. We have produced the fourth edition of collections of video clips this year. This paper shows what kind of our clips and how our video clips changed in ten years.

Introduction and management of inter-campus learning assistant system for distributed campus

Kyushu University consists of several major campuses. Most students are required to go to a couple of campuses to take classes for the first one-and-a-half or two years. Teachers are also expected to go to another campus to teach students from their home campus. The time wasted traveling one-and-a-half hours between campuses is significant for teachers. Using a video-conference system (such as Polycom) seemed to be a good solution; however, the set up procedure before the lecture is time-consuming and troublesome. It is difficult for most teachers to set up such systems. Furthermore, operating the remotecontrol while teaching a class is difficult. Teachers want an easier and more intuitive interface to give a smooth lecture. In response to these requirements, we introduced the Inter Campus Learning Assistant System (iClass) into each distributed campus. The system uses an ordinary video-conference system that is customized for our purpose. The startup processes are automated and operation is performed intuitively with a touch panel. Teachers can operate cameras and other peripherals easily and with little training. We expect to promote the lectures among campuses, making the delivery of lectures between Japan and foreign countries such as our branch office in California easier with iClass. In this paper, we describe the detail, results, and effectiveness of our iClass. Furthermore, we will discuss further applications of such devices.

Producing Video Clips for Information Ethics and Security in Higher Education

A consortium of IT professionals across various universities in Japan has been producing educational video clips regarding information ethics and cyber security issues for university students. The clips were revised and supplemented several times, with the most recent version released in late 2016. This video collection consists of twenty-two short stories involving three university students who were involved in IT issues or incidents. The video topics and original scripts were discussed and written by various university faculty members. Professionals at aproduction company then refined the scripts and made the videos. The video clips have been widely used by many Japanese universities and have been well received by students. Most importantly, the videos raise important issues about information ethics and help students understand their role in computer security.
