Over the decades, the Open Access movement has evolved with the support by academic communities. Following this movement, Kyoto University adopted the Kyoto University Open Access policy in 2015 and has launched the Open Access promotion project in 2016. The project aims to promote open access to scholarly articles as well as open access to rare materials (e.g., manuscripts). In this paper, we summarize our systems to advance open access, focusing on our institutional repository for scholarly articles as well as our digital archive system for rare materials.

This study examines a generic support system prototype in eduinformatics for students selecting a seminar. We have proposed a new inter-disciplinary field called Eduinformatics. It is a combination of the fields of education and informatics. Earlier in 2017, we examined students' submission system and procedure and the result of actually employing this system to match students with specific seminars and teachers. Results revealed several issues with this first prototype system. Therefore, we developed a generic support system prototype in eduinformatics for students selecting a seminar, to improve the earlier model.

With web-based collaborative problem-based learning, learners could more conveniently cultivate their problem-solving capabilities through autonomous learning. Nevertheless, learners are often guided to solve a target problem by the messages announced by teachers during the collaborative problem-based learning (CPBL) processes. Individual learners often could not effectively absorb such standard messages, thus ignoring the important messages from teachers. This study thus employs the modularity Q function as the fitness function of genetic algorithm (GA) to optimally detect communities and uses PageRank measure to accurately find out community opinion leaders according to the social network interaction data of learners in the CPBL process. Based on quasi-experimental design, this study examines whether learners in the experimental group using the two-step flow of communication through opinion leaders to convey messages for solving a target CPBL mission could more significantly enhance web-based CPBL performance, social network interaction, and group cohesion than learners in the control group using the one-step flow of communication through teachers' messages. Analytical results show learners in the experimental group remarkably outperform those in the control group on learning performance and peer interaction under a CPBL environment. Learners in the experimental group present significantly higher group cohesion than those in the control group.

In system development, specification changes are often made to improve or change service. The cause of the specification changes is uncertainty which can not be fixed until the practical use of the system gets started. The handling method of uncertainty has already been proposed, but detailed processes have yet to be defined for developing smart mobility applications. The paper proposes a detailed process for applying the handling method of uncertainty to smart mobility applications, and also propose a method to facilitate to conduct the process employing Model-Driven Development technology. For continued development, we will also refer to how to use operational information to improve requirements and designs, and how to analyze impacts when requirements and design are added or changed. We conducted a case study to demonstrate our proposed method. For the case study, we used parking recommendation application. As a result, two uncertainties were able to be resolved.

This paper discuss about the relationship between the competencies of university students and the score change patterns of the English skills. We analyze the impact of student's competency factors on improving English language skills scores using the Tukey-Kramer Multiple Comparison Test. In order to analyze the improvement of English skills, the concept of score change was used. The results revealed that some "interpersonal" competency factors such as "leadership" and "cooperation" are related to continuous score change.

In today's declining population, the mass production economic model has reached its limit. In recent years, a recycling economy featuring shared services is emerging, and applying this concept to public infrastructure will act as a countermeasure against the declining population. However, to actually achieve "public sharing services", we have to create a high-speed and scalable resource supply-demand matching mechanism. This work proposes a resource supply-demand matching application for a ground transportation system in a city of one million and demonstrates its effectiveness by simulations.

Temporal text mining is widely used in summarization and tracking of evolutionary topic trends. In online collaborative systems like Wikipedia, edit history of each article is stored as revisions. Topics of articles or categories grow and fade over time and retain evolutionary information in edit history. This paper studies a particular temporal text mining task: quickly finding burst patterns of topics from phrases extracted from edit history of Wikipedia articles. We first extract several candidate phrases from edit history by specific features and build time series with edit frequency. Temporal clustering of burst patterns of phrases reveals bursts of topics. However, distance measure for temporal clustering, such as dynamic time warping (DTW), is often costly. In this paper, we propose segmented DTW which decomposes time series into proper segments and computes DTW distance within segments separately. Our segmented DTW shows reasonable speed up over DTW, while the proposed method can identify interesting evolutionary topic burst patterns effectively. Research so far can be applied in domains like trend tracking, temporal relatedness of phrases and popular topic discovery.

The ratio of aged persons is increasing in Japan, and solitary death of them have became one of significant social issues. Our objective in this study is to avoid such misfortune. Some systems that observe their liveliness are presented or developed, but they have rawbacks such as higher costs, miss-alert and so on. In this article, we show two requirement for such system, present a system that satisfies the two, report trial implementation and the result, and conclude with the future direction.

In many real-life situations, it is necessary to optimize two or more objects simultaneously. In such problems, the objectives under consideration conflict with each other, and optimizing a solution with respect to a single objective can result in unacceptable results with respect to the other objectives. The technique of bringing two or more mutually opposite objective functions close to the desired value set up under the constraints is called goal programming. Goal programming is generally applied only to linear problems. Though nonlinear objective functions and constraints may be handled in real-life problems, a method for applying them to nonlinear goal programming is not shown clearly. The aim of this research is to design a decision-making model for solving multi-player nonlinear goal programming. In this research, based on the Linear Physical Programming (LPP) procedure to solve GP with nonlinear constraints, we design a model to deal with multi-player nonlinear GP. The part of the developed procedure corresponding to negotiation among several decision makers, called Suriawase process, was installed using the concept of robust optimization. Finally, to clarify the meaning of multi-player nonlinear GP procedure, numerical experiments using the production planning problem in the supply chain were performed.

Smart mobility services evolve rapidly in excessive competition with rivals in the market. Meanwhile, service suppliers cooperate partially to avoid exhaustion and concentrate on their core business. Therefore, homebrew and external services have dependency one another. This paper proposes some software engineering practices to develop and operate such smart mobility services. An interorganizational architecture is imported from the ITS domain as a shared view for service suppliers in competition and cooperation. Each service supplier construct an intraorganizational architecture for its home-brew services in microservice architecture style. Technical practices are basically feature oriented. Services are comprehended by the feature model and their boundaries are managed based on it. Supply chain management of services is conducted based on the data flow diagram traceable from the feature model. The contract and its variation on service supply is managed and accounted by the assurance case. Risks on sustainable service supply are studied with failure modes and effects analysis.
