- Abstract
The IADIS CELDA 2012 Conference intention was to address the main issues concerned with evolving learning processes and supporting pedagogies and applications in the digital age. There had been advances in both cognitive psychology and computing that have affected the educational arena. The convergence of these two disciplines is increasing at a fast pace and affecting academia and professional practice in many ways. Paradigms such as just-in-time learning, constructivism, student-centered learning and collaborative approaches have emerged and are being supported by technological advancements such as simulations, virtual reality and multi-agents systems. These developments have created both opportunities and areas of serious concerns. This conference aimed to cover both technological as well as pedagogical issues related to these developments. The IADIS CELDA 2012 Conference received 98 submissions from more than 24 countries. Out of the papers submitted, 29 were accepted as full papers. In addition to the presentation of full papers, short papers and reflection papers, the conference also includes a keynote presentation from internationally distinguished researchers. Individual papers contain figures, tables, and references.

6. On-Campus E-Mail for Communicative Writing.
- Author

Miyao, Mariko
- Abstract
A project using on-campus electronic mail (e-mail) to teach communicative writing in English as a Second Language to Japanese junior college students is described. The project had three stages: (1) planning; (2) piloting with a small group of students; and (3) implementation in three large classes (n=55, 28, 36). The aim was to help students write more communicatively and with less anxiety. Planning involved gaining student access to the campus e-mail system, first on a small scale and later with access to more computer services. The pilot involved nine second-year students in a graduation project. Students needed to be familiarized with two-way message exchanges. However, after exchanges began, student-teacher interactions became more interesting. Learning word processing and spell-checking in English and document transfer were initially a challenge. Implementation with three larger classes, in which most students were familiar with e-mail, began with a paired self-introduction writing activity. Partners questioned each other, commented on introductions, and made grammatical corrections, helping each other refine the final product. Teacher feedback was provided weekly. It was found that the method facilitated timely and comfortable communication. The experiments provided insights into advantages, difficulties, and effective procedures for computer-based communication. (MSE)

9. The Telecommunications Stranglehold on Europe's Information Use: Practical Constraints for SMEs and Economic Assessment Based on Cost Models.
- Author

Delcroix, Jean-Claude
- Abstract
There is a general feeling that European telecommunications are delaying the introduction of new information services. This paper responds to some of the questions concerning online information. The views result from research work at DECADE (Belgium) on the requirements of smaller organizations on the one hand and on telecommunications costs on the other. In the new information age, competition is forcing all companies and increasingly also SMEs (small and medium enterprises) to get and handle a lot of information. Speed and costs are two key competitive factors as SMEs operate with rather short term constraints and have very low purchasing budgets. Traditional online services appear far too expensive to use and very difficult to learn. The World Wide Web matches the knowedge acquisition paradigm of end-users and SMEs much better than traditional online services. From this perspective, in most European countries the current offer of online information services and related telecommunications methods is seriously lagging behind compared to the United States. This paper compares the network costs and the Internet-based services in Europe and in the United States; data is also provided about Japan. Graphics are shown with price comparison for leased lines and for Internet access. The paper then investigates shortcomings and looks at the likely evolution towards TCP/IP data networks and bandwidth costs per user. In the conclusion, key economic issues are addressed regarding information publishers, Internet/intranet service providers and of what European users might do. (Contains 10 references.) (Author/AEF)

10. Development of Online Database Services in Japan and Perspectives on Asia.
- Author
-
Miyakawa, Takayasu
- Abstract
This paper outlines the market developments, governmental promotion policies, and efforts by private industries for online database services in Japan since the late 1970s. The combination of these efforts over the years has resulted in an online database service market of US$20 billion annually, of which approximately one third is Western online services. Growth in the conventional database service market leveled off in the early 1990s, partly because of the general economic stagnation and partly because of rapid and profound change in the environment for information usage. New opportunities have been provided by the changes in computer usage as a result of corporate downsizing trends, rapid progress in multimedia and digital technology, wide-spread information networks--especially the Internet, and a steadily emerging personal and home market. Experimental programs for digital libraries have already started. The idea of end-user searches of digital libraries through a network is exciting but threatening for everyone in the online services industry. In addition to Japan, online database producers and vendors are now emerging in newly industrializing countries and areas in Asia such as Korea, Taiwan, Singapore, Thailand, and Malaysia. The market has started to grow, and within a decade the fourth largest market for online services will be in Asia, after the American, European, and Japanese markets. (Author/SWC)

- Abstract
The present state of the educational use of computer communications networks in Japan is outlined. Computer communication is now growing rapidly in Japanese society as a whole, and its educational community is not an exception. After giving general figures on the use of computers in Japanese education and describing government proposals on information networks for education, this paper summarizes different types of online educational activities. These activities include databases for instructional materials, information exchange and computer conferencing on some major networks, local and grassroots networks, and academic networks. Research activity on the use of educational computer communication is reviewed, and the need for further research is emphasized, especially on the psychosocial aspects of computer communication. Twelve figures illustrate the discussion. (Contains 29 references.) (Author/SLD)

12. Online Operation Guidance of Computer System Used in Real-Time Distance Education Environment
- Author

He, Aiguo
- Abstract
Computer system is useful for improving real time and interactive distance education activities. Especially in the case that a large number of students participate in one distance lecture together and every student uses their own computer to share teaching materials or control discussions over the virtual classrooms. The problem is that within this type of education environment the students need to learn the operation of the support system which runs on their own computers. It is important that the system can support the students to learn the system. This paper proposes a support system for the online operation guidance of computer system in real time and the interactive distance education environment, RIDEE-OOG. The features of this system are: (1) a built-in function in the original distance education support system, (2) it is easily used by the teacher in real time distance lectures, and (3) it does not burden the students. This paper reports RIDEE-OOG's basic design issues and implementation. The effectiveness of this proposal has been confirmed by experiments. (Contains 7 figures.)

- Abstract
In 2004-2005, The National Library of the Netherlands (Koninklijke Bibliotheek) conducted a survey for the IFLA-CDNL Alliance for Bibliographic Standards (ICABS)--an alliance founded jointly by the International Federation of Library Associations (IFLA), the Conference of Directors of National Libraries (CDNL) and the national libraries of Australia, Germany, the Netherlands, Portugal, the United Kingdom, and the U.S.--on the use and development of standards in digital archiving within the international library world. The survey resulted in the present report, and gives an overview of current digital preservation practice in the 15 national libraries of Australia, Austria, Canada, China, Denmark, France, Germany, Japan, Netherlands, New Zealand, Portugal, Sweden, Switzerland, the United Kingdom and the United States of America. The main focal points in the survey are the use of standards in operational safe place environments (the current state of affairs of initiatives on electronic repositories), and the current state of affairs with respect to, and the need for permanent access strategies (such as migration and emulation). The survey also provides an overview of current national and international projects on digital preservation. The study made use of desk research, interviews and an analysis of new developments. This report contains two parts. Part One provides an analysis of the current state of affairs at 15 national libraries. Part Two contains the detailed overviews per library. Each overview is divided into four sections: General; Digital Repository; Preservation Strategies; and Current Activities. The report contains a foreword written by Dr. Wim van Drimmelen, Director General, Koninklijke Bibliotheek, and a foreword written by Renate Gompel, Chair of ICABS. Appendices includes a list of references and acronyms and the Report of the National Library of Australia on Guidance for Digital Preservation: A Summary. It is hoped that this report will serve as a useful guide for libraries and cultural heritage institutions as they face the future challenges of long-term archiving and preservation.

Schmitt, Lothar M. and Christianson, Kiel T.
- Abstract
Pedagogical features and implementation of a UNIX-based management system (UNIEM) designed to support the instructor in teaching English as a second language using a network of workstations are described. The application discussed here is for teaching English composition to students at the University of Aizu (Japan). UNIEM is constructed to assist the computer novice in these tasks: sending out assignments using electronic mail (e-mail) on pre-set dates; reminders of missing homework when necessary; sorting of homework submitted using e-mail; enforcing submission deadlines and required homework length; partial evaluation of homework, particularly regarding mechanical mistakes such as spelling; distribution of evaluation results to students; reformatting of student writing for correction purposes; use of global or specialized vocabulary; identification and collection of authentic, interesting, or critical examples of grammar patterns for presentation in class; generation of statistical information; and graphic display of data. Implementation of these tools and potential for customization, possibly in connection with a specific research objective, are discussed. A program decomposition principle is also presented. (MSE)

Narita, Shigeru
- Abstract
Following a brief overview of the Japanese educational system and its programs for handicapped children, the role of microcomputers in Japan's schools is described. Most secondary and some elementary schools in Japan have acquired computers to enhance the processes of learning and teaching. In schools for the handicapped, computers are also being utilized, especially in programs for hearing and visually impaired students. A shortage of special education courseware has been a problem, and provincial education centers and individual teachers are developing appropriate courseware. Hardware developments include the design of special input-output devices designed to meet handicapped students' needs. Training is necessary to help teachers understand the technology and the role changes brought about by computers. Workshops are sponsored by the National Institute of Special Education to train special educators in the use of computers. Japan has several commercial electronic networks and bulletin boards that link scattered projects, but a need is felt for a network solely intended for special educators. Appended to the paper are statistical data on the numbers of special schools and numbers of handicapped students by handicapping condition, by type of school, and by grade level. (JDD)

- Abstract
The instructional media created by microcomputers interconnected by modems to form long-distance networks present some powerful new opportunities for education. While other uses of computers in education have been built on conventional instructional models of classroom interaction, instructional electronic networks facilitate a wider use of apprenticeship education, in which students learn skills and acquire knowledge in contexts similar to those in which they will be used. To investigate these possibilities, an instructional electronic network (the Intercultural Learning Network) interconnecting students and teachers in the United States, Mexico, Japan, and Israel has been developed. For one project conducted in this network, students tackled a problem in their own community, the problem of the shortage of water. By addressing a problem shared across the different locations, students learned to transfer solutions used elsewhere to their own problems. They also acquired science concepts in an instructional setting that provided dynamic support for the acquisition of problem solving skills. This study raises a challenge to education: that the dominant form of instruction could become "teleapprenticeships." In this form of instruction, students would participate in globally distributed electronic problem solving networks, jointly tackling problems with other students, with teachers, and with adults outside the school.

- Abstract
The Ad Hoc Council on Educational Reform pointed out in 1987 that Japanese education must prepare for the ever-increasing information needs of the future, and in 1988, a proposal for the development of information networks was published by the Ministry of Education, Science, and Culture. This proposal recommended the utilization of a wide range of media in support of lifelong learning activities and the establishment of such systems in various localities. Three models for information dissemination using personal computer communications (at the school, regional, and national levels) are described in the first section of this document. The remaining four sections describe currently-existing information networks throughout the country, including: (1) the Audiovisual Public Board (AV-PUB) System, a telecommunications system comprised of a database on audiovisual materials and a bulletin board for exchanging information related to audiovisual education; (2) commercial computer networks throughout Japan (used primarily by teachers, boards of education, and researchers); (3) computer networks established by local boards of education and similar organizations; and (4) the Academic Information Center System, which provides online databases and an electronic mail service for universities and research institutions throughout Japan. Fifteen figures are included in this document. (GL)

- Abstract
New policies are needed for the U.S. telecommunications industry. The continuation of current policies--which emphasize customer and convenience services to the near exclusion of developing domestically produced equipment and improving infrastructure--will constrain the domestic growth of U.S. corporations and make it difficult for smaller American firms to use sophisticated equipment and services. A new policy regime should focus on linkages between network infrastructure development and technological innovations in equipment, fostering the joint development of both. International competitors such as Japan and the European Community have already established policies to upgrade the existing telecommunications infrastructure and lead in the development of strategic technologies such as high definition television (HDTV). These competitors are also rapidly organizing an Integrated Services Digital Network to be a cornerstone for the development of future high technology industries. The United States needs a comprehensive and coherent approach to the industrial issues and regulatory concerns facing its telecommunications industry. One immediate step should be to establish an independent Department of Communications that would create a unified approach to the nation's economic base in the next decades. (31 references) (GL)

- Abstract
The educational potential of computer networks will be realized only when educators stop focusing on technical connections and start asking how educational activities that are supported on computer networks can make a significant contribution to education. Computer networks can contribute to accomplishing educational goals in language arts (by improving reading and writing skills); social science (by facilitating international and intercultural sharing of aspects of daily life, news stories, holiday customs, and social problems); science (by extending the range of observations for solving scientific problems); and foreign language learning (by using the Intercultural Learning Network as a functional learning environment, and increasing motivation for the study of foreign languages in the United States and for the improvement of English communication skills in foreign nations). Among the central issues that have evolved from the collaborative work of those using educational networks are that establishing technical connections between participants is only the first step. An active role for the classroom teacher in designing and implementing such activities is vital if networks are to reach their potential. (30 references) (GL)

- Abstract
A worldwide international computer network, called the Intercultural Learning Network, has been developed to provide students from different cultures with opportunities to work cooperatively. Prototype activities have been developed and tested which facilitate and contextualize interactions among secondary and college students. Joint projects in language, science, and social studies are carried out using an overnight electronic network to coordinate parallel surveys and to exchange findings of joint research. Five important questions are addressed in this research: (1) Is the Intercultural Learning Network technically feasible? (2) Is it economically feasible? (3) Is it useful for instructional purposes? (4) What organizational structures are required? and (5) Can the system support multiple languages and cultures? Findings indicate that because of continuing technological advances, cross cultural activities have become economically and technically feasible. The level of technical expertise needed is reasonably accessible to any motivated teacher. The continuing costs involved are small enough to be covered as incidental expenses by many school budgets. The educational potential of the activities is promising. Some prototype activities have been developed to facilitate the initial interactions across cultures. Joint participation in such activities is a good way to encourage multilingualism and awareness of other cultures. Further research is being conducted to evaluate the long term effects of international networking on students' attitudes, knowledge, and cultural awareness. (12 references) (Author/GL)

The key features of computer networks available for a disaster situation are reliable, fault tolerance, and self‐configurable. Therefore, using a wireless mesh network for disaster prevention and recovery system has gained much attention from the research community in the last decades. In addition, from the practical aspects of the network infrastructures of the disaster system, we should assume the core capabilities such as wireless connectivity in a wide range, ease of use, and low cost so on. In this paper, we propose an interface mode assignment method for reconstructing a route from an isolated router to a gateway (GW) router in a wireless mesh network based on IEEE 802.11 infrastructure mode after a disaster occurrence. The proposed method assigns an adequate mode to each interface in an isolated router to recover the network reachability in a distributed manner. Simulation results show the effectiveness of the proposed method via two different scenarios. © 2020 Institute of Electrical Engineers of Japan. Published by Wiley Periodicals LLC.

Elucidation of the structure of human sexual networks is not only an interesting topic in the area of social networks but also an important clue for understanding the spreading risk of sexually transmitted infections (STIs). Some previous studies have indicated that sexual networks are scale free, while others have suggested that they are not. We conducted a Web-based survey on sexual contact in Japan to collect data on cumulative (total) heterosexual partners and the number of recent (in the last three or previous three months) heterosexual partners. To determine whether the number of heterosexual contacts in Japan has a power-law tail, we used maximum likelihood fitting methods and Kolmogorov-Smirnov tests. For confirmation, we also used the Akaike information criterion (AIC) and the Bayesian information criterion (BIC). Our results indicate that the distributions of the number of sexual partners in Japan have power-law tails. [ABSTRACT FROM AUTHOR]

Graph operations produce new classes of graphs from initial ones which in turn may be useful for the modeling and recognition of computer network designs. A Pythagorean fuzzy set-based model offers more flexibility to cope with human evaluation information as compared to intuitionistic fuzzy model. The main objective of this research study is to expand the area of discussion on Pythagorean fuzzy graphs by establishing fruitful results and notions related to an operation on Pythagorean fuzzy graphs called strong product. Certain concepts, including connectedness, completeness, regularity and partially regularity of strong product Pythagorean fuzzy graphs are discussed. It is shown that the strong product of two regular Pythagorean fuzzy graphs may not be regular. Moreover, some necessary and sufficient conditions for the strong product of two regular Pythagorean fuzzy graphs to be regular are established. Finally, an algorithm for Pythagorean fuzzy multi-criteria decision making is presented and problem concerning to evaluation of domestic airlines in Japan is solved to demonstrate the applicability of PFGs in realistic scenarios.

The aim of this study was to investigate the running pace and step characteristics among various competitive-level 400-m hurdlers through inter-group and intra-athlete comparisons. We analysed spatiotemporal data involving the split time, mean step length (SL) and mean step frequency (SF) for 13 male world-class and 14 male national-level 400-m hurdlers. We analysed 16.5 ± 3.9 races for each world-class hurdler and 19.8 ± 6.0 races for each national-level hurdler (the total number of analysed runs was 491) using publicly available television and internet broadcasts. Inter-group comparisons showed that both first- and latter-halves split times of the world-class hurdlers were significantly shorter than those of the national-level hurdlers. In the latter-half phase, no significant differences of SL and SF were observed between the world-class and national level hurdlers. Intra-athlete comparisons showed that no athletes favoured only first-half phase in terms of running speed in short finish times. In contrast, finish times of all hurdlers were sensitive to running speed in the latter-half phase. In the latter half of the race, 18 of the 27 hurdlers were identified as being SF reliant during speed enhancements; running speed of the other 9 hurdlers were also sensitive to high SF. In conclusions, important findings regarding high performance in inter-group comparisons do not always corresponded with those in intra-athlete comparisons. All athletes and coaches should first prioritize maintaining high running speeds in the latter half of 400-m hurdles rather than in the first half of the race. [ABSTRACT FROM AUTHOR]

Collective emotion has been traditionally evaluated by questionnaire survey on a limited number of people. Recently, big data of written texts on the Internet has been available for analyzing collective emotion for very large scales. Although short-term reflection between collective emotion and real social phenomena has been widely studied, long-term dynamics of collective emotion has not been studied so far due to the lack of long persistent data sets. In this study, we extracted collective emotion over a 10-year period from 3.6 billion Japanese blog articles. Firstly, we find that collective emotion shows clear periodic cycles, i.e., weekly and seasonal behaviors, accompanied with pulses caused by natural disasters. For example, April is represented by high Tension, probably due to starting school in Japan. We also identified long-term memory in the collective emotion that is characterized by the power-law decay of the autocorrelation function over several months. [ABSTRACT FROM AUTHOR]

MACHINERY industry , *MACHINE tools , *COMPUTER networks - Abstract
The article presents an overview and comparison of the U.S., Japanese and German machine tool industries. Remote repair, diagnostics and maintenance (RRDM) is a broad term that incorporates various technologies and applications. It consists of fully integrated computer and network applications that automatically monitor performance, diagnose problems and request attention from service technicians for specific problems. The technological state of the machine tool industries in the U.S., Japan and Germany is similar. The U.S. machine tool industry lacks the clear competitive profiles of Germany or Japan. Regarding controllers, the U.S. and Germany now tend toward open concepts and interfaces while Japanese machine. All three countries recognize the strategic potential of RRDM applications with only long-term benefits. The research support for these long-term applications differs between the countries. In Japan, research is mostly funded by private firms, whereas in Germany, local governments have historically provided a great deal of research funding. In the U.S., the federal government supported the further development of RRDM mostly through research funding to NASA, DARPA and the U.S. military in support of specific space and defense-related issues.

The article informs that one of the most significant trends in personal computer usage during the last 10 years has been networking. The Internet is perhaps the best known and most pervasive example of networking technologies and has proven to be an easy and efficient way of delivering a wide variety of services to millions of connected users. Another important technology trend occurring during the last decade has been the growth and increasing sophistication of wireless telephony. The article informs that the growth and success of iMode in Japan has provided considerable food for thought for wireless Internet industry analysts. It concedes that based on the discussion of technology acceptance theory, it is perhaps unlikely that iMode's success will be emulated to the same extent or as easily in other markets. Conditions that have combined to create the fertile environment for growth of iMode in Japan do not necessarily exist elsewhere.

This article focuses on accessing Internet through devices other than personal computer. An enormous number of low-cost Internet-enabled appliances and sensors, actuators and communication devices will enter the market. For example, almost 16 million Internet capable cellular phones entered the Japanese market over the past 18 months, millions of radio LAN devices are in operation and Internet-enabled cameras with radio links have been demonstrated. One could as easily imagine a single purpose device whose principal use is to tune in web-based sources of digital sound and render them audible. The same already happens with MPEG3-encoded audio that can be downloaded and played at leisure or in real time after an interval of buffering to overcome variations in packet inter-arrival time across the network. Despite the apparent demise of the Napster model and its freeform peer-to-peer sharing of audio files, the music industry is being turned upside down. Replacing much of the traditional physical distribution with online digital distribution, such appliances may also point the way toward other special purpose devices for rendering Internet delivered digital content in a variety of ways, including as video, formatted text, images, sound, or a combination of all media.

The Internet, a global computer network enabling people to send and receive information anywhere in the world, also functions as a local medium of communication. This study focuses on the role of the Internet in transmitting local news and examines the effects of community population concentrations as socio-ecological environments on the use of local news media consumed online and offline. Data from 1367 respondents across 156 Japanese communities were used to analyze the relationships between type of community and type of news source. The findings suggest that people who live in highly populated communities tend more often to use the Internet to access local news, whereas those in less populated communities tend to use more traditional mass media. However, the results of this study did not show a relationship between population concentrations within communities and the acquisition of international news, nor did the social features of residents adequately explain the effects of population concentration on the acquisition of local news. These results are consistent with theoretical predictions based on network externalities, urbanism, and collective action. The findings indicate that local news consumption is embedded in local social contexts in a way that international news is not, reinforcing the importance of urbanism in the information age.

The ability to ascertain the extent of product sale fluctuations for each store and locality is indispensable to inventory management. This study analyzed POS data from 158 convenience stores in Kawasaki City, Kanagawa Prefecture, Japan and found a power scaling law between the mean and standard deviation of product sales quantities for several product categories. For the statistical domains of low sales quantities, the power index was 1/2; for large sales quantities, the power index was 1, so called Taylor’s law holds. The value of sales quantities with changing power indixes differed according to product category. We derived a Poissonian compound distribution model taking into account fluctuations in customer numbers to show that the scaling law could be explained theoretically for most of items. We also examined why the scaling law did not hold in some exceptional cases. [ABSTRACT FROM AUTHOR]

The article discusses latest technology frontiers. The Japanese corporate officials proclaim enthusiastically the potential of the "Hypernetwork" (as they call Cyberspace) to tenderize the hierarchical rigidity of both their own organizations and Japanese society. If they are right, no organism with an immune system as subtle and robust as that of the larger, unindividuated Japanese whole is going to admit without response a virus which promises to attack its structural integrity. And not without cause. This is, after all, a society which is also largely free of such artifacts of individuality as random and violent crime. Perhaps if there were other persuasive reasons for Japan to jack into the Net, they might be willing to tolerate the reconstructive risks of networked computing. But why would people whose language is written, not typed, be eager to enter an environment where they would have to express themselves in the hard little alphanumerics of lower ASCII? In fact, the recently developed Kanji keyboard does make it possible for the Japanese to input their data with something besides a calligraphy brush.
