ASAKAWA Makiko, AOKI Takaaki

The Journal of Information Science and Technology Association Vol. 75 ( 2 ) page： 79 - 85 2025.2

Language：Japanese Publishing type：Research paper (scientific journal) Publisher：Information Science and Technology Association, Japan

In recent years, the importance of Research Data Management (RDM) has been increasing, driven by the perspectives of research openness and strengthening research integrity. Graduate students, as early-career researchers, must acquire foundational RDM knowledge and integrate it into their research practices. However, effective methods to raise awareness and provide practical strategies for RDM implementation remain underdeveloped. This paper presents the design and application of the “RDM Interview Sheet”, a tool created to guide graduate students in reflecting on and explaining their research data management practices.

<p>The “Inter-university Upper atmosphere Global Observation NETwork (IUGONET)” project has developed a metadata database for ground-based observation data in Solar-Terrestrial Physics. In order to make this metadata database accessible to a wide range of research communities and the general public, we converted metadata in different metadata schema and registered them in academic institutional repositories. As a result, through regular harvesting between databases, the metadata has also been registered in the Institutional Repositories Database (IRDB), the Data Catalog Cross-Search System, and Google’s Dataset Search, significantly enhancing the visibility and accessibility of research data. Furthermore, effective metadata management was implemented in response to research metadata maintenance requests from policy-making bodies.</p>

Takaaki Aoki

The Journal of Information Science and Technology Association Vol. 74 ( 4 ) page： 124 - 128 2024.4

Authorship：Lead author Language：Japanese Publishing type：Research paper (scientific journal) Publisher：Information Science and Technology Association, Japan

The open science movement, initiated in the early 2010s along with the context of data-driven science and concerns over research reproducibility and accountability, demands practical actions for managing and sharing research data effectively. This requires the response of all stakeholders involved in academic activities, not only researchers but also disciplinary communities and funding agencies and so on. In particular, academic institutions face diverse and complex issues as they mediate between researchers and other stakeholders. This paper discusses the approach to organizational support for research data management required for academic institutions and the initiative efforts being made.

Kazuki Takeda, Yasuyuki Nakamura, Takaaki Aoki, Shoji Kajita

SIG Technical Reports Vol. 2024-CLE-42 ( 2 ) page： 1 - 6 2024.3

Language：Japanese Publishing type：Research paper (conference, symposium, etc.) Publisher：Information Processing Society of Japan

In this presentation, we introduce a browser extension named “Comfortable Sakai,” which was developed by students to enhance the functionality of the Sakai LMS. Initially developed as “Comfortable PandA” specifically for Kyoto University, it lacked compatibility with other Sakai LMS platforms, leading to a limited usage. To address this, while keeping its core features, we added support for internationalization (i18n) and localization (l10n) and removed dependencies unique to Kyoto University. This development aimed to make the extension usable with various Sakai LMS systems around the world. This report will cover the development of this extension and its evaluation by Sakai LMS users.

Developing research data management services that support research data lifecycle has become an international trend in response to today's movement promoting open science. On the one hand, the selection and use of the developed research data management services are left to the discretion of each researcher. On the other hand, universities and academic institutions must establish research data management services at the institutional level to support researchers and strengthen their institutional governance. However, due to the wide range of functions required of research data management services, it is difficult for institutions to evaluate the achievement of their service maturity level. It is essential to establish a self-assessment framework to measure the degree of achievement for developing the services comprehensively and consistently. In this study, we design a self-assessment framework for evaluating the maturity level of research data management services in academic institutions. We analyzed the existing RDM service maturity models and extracted common elements to understand the services provided by each institution. We also developed key performance areas by each element and evaluated the framework through a large-scale questionnaire survey targeting institutions of different scales and characteristics. The self-assessment framework used in this study structures institutional research data management services and enables quantitative comparisons from the perspective of service providers. Also, the framework helps identify issues or points of investment in implementing new research data management services by institutional scales or characteristics.

Enterprise Architecture Approach for Institutionalized Research Data Management Service

AOKI, Takaaki

Vol. 2021-IOT-55 ( 7 ) page： 1 - 5 2021.8

Authorship：Lead author Language：Japanese Publishing type：Research paper (conference, symposium, etc.)

Research data management (RDM) is the practice of defining what research data is to be handled and how it is to be handled from the beginning to the end of a study. This includes all operations on research data, such as obtaining, storing, sharing, publishing, and destroying, which are often chosen at the discretion of each researcher. On the other hand, with the spread of open science and the strengthening of governance in academic institutions today, there is a need to unify and standardize RDM methods at the institutional level. The introduction of the institutional-wide RDM support services may include various conflicts, such as the intentions of the organization and researchers, cost effectiveness, etc. It is necessary to clarify these gaps and find a point of agreement between the institution and the researchers. In this article, we will discuss the concept of the business model assumed when an organization introduces RDM support service, and how to compose an enterprise architecture to realize it.

Secondary ion mass spectrometry (SIMS) is a method with high surface sensitivity that allows both elemental and molecular analysis. The MeV-SIMS technique uses heavy ion beams with energy in the MeV range, and samples can be measured under ambient conditions because of the high transmission capability of these ions at low vacuum pressures. Ambient MeV-SIMS is a suitable method for investigating the reactions at the electrode–electrolyte interface. In contrast, however, in this method, chemical noise originating from ionized residual gases can be found with high intensity. Under the conditions, signals from the surface have to be distinguished from the chemical noise. In this paper, MeV-SIMS measurements of a Li-containing electrolyte were performed and a method was established for separating out chemical noise and signals from the sample surface. The detection of a number of Li-containing electrolytic compounds from the sample surface by an ambient MeV-SIMS system was successful.

IPSJ SIG Technical Report Vol. 2020-IOT-48 ( 14 ) page： 1 - 7 2020.2

Authorship：Lead author Language：Japanese Publishing type：Research paper (conference, symposium, etc.)

Under the social demands for the promotion of open science and the research fairness, academic institutions are urged to facilitate the organizational research data management (RDM) framework, such as policy development, provision of IT infrastructure, education for research data literacy, etc. The survey about the comprehension of the RDM and demand to the organization considered by the members is one of the initial actions for the institutes to design the organizational RDM environment. Several research institutes jointly developed the standard questionnaire template and guideline to survey the awareness and demand of RDM among their researchers. The development of a questionnaire template was useful to reduce the initial effort survey and to compare the results between institutes. The paper will report the structure of the standard questionnaire template and discuss the framework for promoting the organizational RDM environment at institutions.

IPSJ SIG Technical Report Vol. 2019-IOT-47 ( 17 ) page： 1 - 8 2019.9

Language：Japanese Publishing type：Research paper (conference, symposium, etc.)

There is a worldwide trend to manage and share research data resulting from research activities. Research data, resulting from research activities, are in general managed by researchers; however, seen from efficiency and accountability point of view, academic institutions are increasingly held responsible for providing infrastructure and support research activities of researchers within institution as well as being accountable as an institution in case of scientific misconducts. Nonetheless, as research data management is a relatively new trend, it has not made that far at Japanese academic institutions. This work attempted to clarify the issues the academic institutions face when introducing research data management into the institution by discussing the issues with a workgroup of several universities. The need of having various stakeholders within institution on the same page, the need of research data management to be properly positioned in the university strategy, the need to recognize the research data as assets of the institution, the need of institution to provide e-infrastructure and support system for research data management, and the need for research data management training were raised. To address these issues and raise awareness of university administration, AXIES, which is the association of ICT centers of Japanese universities, drafted the “Recommendations for Research Data Management at Academic Institutions.” This work is to be followed by 1) questionnaire survey template to be used by universities to understand the needs of researchers on research data management and 2) collection of case studies of research data management implementation.

<p>Recent progress of SIMS technique is reported in conjunction with novel primary ion beams and advanced mass spectrometers. Numerous applications of SIMS have been proposed and demonstrated in last decade, covering from organic semiconductors to cells and tissues. One of the biggest problems was "Static-Limit" for analysis of organic molecules, which is very fragile for ion bombardment. After innovation of massive cluster ion beams, the issue of "Static-Limit" has been overcame. This opens a new possibility for SIMS to analyze organic materials. Ultra-high mass resolution mass spectrometer, MS/MS technique, cationization enhancement and future prospects of SIMS are discussed.</p>
