universities, Moodle and cross-university LMSs have been implemented, and LMS log data are becoming huge. In order to handle such a large amount of data, it is effective to use cloud computing. However, since LMS log data contain many personal information, it is often necessary to anonymize or pseudonymize the data in order to use them on cloud computing. In this paper, we implemented a log analysis environment that combines an organization's internal server and a cloud environment by using the GakuNin-cloud on-demand construction service provided by NII. In this environment, LMS logs are stored in the cloud with pseudonymization, and the pseudonymization is automatically removed by using a proxy when analyzing the logs. We will describe a case study of applying this environment to Moodle at Gunma University.","subitem_description_type":"Other"}]},"item_4_biblio_info_10":{"attribute_name":"書誌情報","attribute_value_mlt":[{"bibliographicPageEnd":"7","bibliographic_titles":[{"bibliographic_title":"研究報告教育学習支援情報システム（CLE）"}],"bibliographicPageStart":"1","bibliographicIssueDates":{"bibliographicIssueDate":"2021-03-18","bibliographicIssueDateType":"Issued"},"bibliographicIssueNumber":"23","bibliographicVolumeNumber":"2021-CLE-33"}]},"relation_version_is_last":true,"weko_creator_id":"44499"},"id":210594,"updated":"2025-01-19T18:06:06.239082+00:00","links":{},"created":"2025-01-19T01:11:48.398134+00:00"}
