(World Wide Web）クライアント・サーバ方式を選択し，実際にWWWクライアント・サーバ方式遠隔回線制御システムを開発した．その有効性を実証するため，学生および教官を対象にした遠隔回線制御の操作実験を実施して，遠隔回線制御方式の比較評価を行った．その結果，局切替操作および応答速度の点でWWWクライアント・サーバ方式の優位性が確認された．","subitem_description_type":"Other"}]},"item_2_description_8":{"attribute_name":"論文抄録(英)","attribute_value_mlt":[{"subitem_description":"We have developed a remote link control system which remotely switches transmitting stations,so that one can remotely use the inter-university satelite network(Space Collaboration System:SCS).The SCS is used for collaborative lectures,seminars,and symposiums with audio and video and has been playing an important role in distance education.However,the utilization is limited to one room in the campus because of the situation that one VSAT(Very small Aperture Terminal) station is built.The primary requirement is to extend the distance range of the SCS utilization.In this paper,we discuss possible three methods of remote link control which is necessary for remote use of the SCS.We then selectedthe WWW(World Wide Web) client/server method which is superior in extensity and flexibility,and actually constructed the remote link control system with the WWW client/server method.To evaluate its effectiveness,we conducted verification experiments of the remote link control for students and professors.The result confirm that the WWW client/server method is superior in the switching operation and the response speed.","subitem_description_type":"Other"}]},"item_2_biblio_info_10":{"attribute_name":"書誌情報","attribute_value_mlt":[{"bibliographicPageEnd":"3966","bibliographic_titles":[{"bibliographic_title":"情報処理学会論文誌"}],"bibliographicPageStart":"3957","bibliographicIssueDates":{"bibliographicIssueDate":"1999-11-15","bibliographicIssueDateType":"Issued"},"bibliographicIssueNumber":"11","bibliographicVolumeNumber":"40"}]},"relation_version_is_last":true,"item_2_alternative_title_2":{"attribute_name":"その他タイトル","attribute_value_mlt":[{"subitem_alternative_title":"協調学習支援"}]},"weko_creator_id":"1"},"id":12491,"updated":"2025-01-23T01:36:31.137537+00:00","links":{},"created":"2025-01-18T22:46:50.092204+00:00"}
