However, about half have not created it. One of the reasons for this is the lack of information on evacuation methods. In this study, we focused on \"dragging evacuation\" as an assistance method for evacuating upstairs in the event of a flood. Dragging evacuation is possible with a small number of caregivers and a small amount of assistance. We decided to examine the effectiveness of dragging evacuation. We thought we needed to know how many facilities for the elderly could evacuate residents upstairs to their own facilities in the event of a tsunami. Surveys were conducted at facilities for the elderly in four cities along the Pacific coast of Hokkaido. About fifty-five percent of facilities for the elderly in the tsunami inundation area can save the lives of residents by evacuating upstairs to their own facilities. This data was based on materials related to \"building structures that can withstand tsunamis\" by the Ministry of Land, Infrastructure, Transport and Tourism. Next, we conducted an experiment on the amount of assistance required for dragging evacuation. The experiment was conducted on the assumption that two caregivers would evacuate the elderly who have difficulties in self-evacuation upstairs using the dragging evacuation method in facilities for the elderly. Two subjects lifted a 50 kg humanoid dummy on a slope set up on a staircase with a slope of 33 °. We measured and considered the pulling force and the required time. In addition, two subjects lifted 45 kg (measuring equipment and humanoid dummy) upstairs on the slope installed on the U-Shaped staircase which includes a landing at the switchback. The pulling force and the required time were measured. The experiment was repeated 3 times on each pair. We propose a staircase structure that enables efficient dragging evacuation. The slope of 28 ° recommended by the new barrier-free law is suitable. The landing is easy to turn around with a depth of 1810 mm and a width of 2900 mm. The width of the stairs is 1650 mm, which is suitable for dragging evacuation. We will inform local governments and facilities for the elderly that the dragging evacuation method is one of the effective assistance methods for evacuation upstairs in the event of a disaster in facilities for the elderly. I hope that the managers of facilities for the elderly will use this to help formulate specific evacuation plans.","subitem_description_language":"en","subitem_description_type":"Abstract"}]},"item_81_dissertation_number_13":{"attribute_name":"学位授与番号","attribute_value_mlt":[{"subitem_dissertationnumber":"甲第465号"}]},"item_81_identifier_registration":{"attribute_name":"ID登録","attribute_value_mlt":[{"subitem_identifier_reg_text":"10.15118/00010390","subitem_identifier_reg_type":"JaLC"}]},"item_81_subject_9":{"attribute_name":"日本十進分類法","attribute_value_mlt":[{"subitem_subject":"528","subitem_subject_scheme":"NDC"}]},"item_81_text_12":{"attribute_name":"学位の種別","attribute_value_mlt":[{"subitem_text_language":"ja","subitem_text_value":"課程博士"}]},"item_81_text_14":{"attribute_name":"報告番号","attribute_value_mlt":[{"subitem_text_language":"ja","subitem_text_value":"甲第465号"}]},"item_81_text_15":{"attribute_name":"学位記番号","attribute_value_mlt":[{"subitem_text_language":"ja","subitem_text_value":"博甲第465号"}]},"item_81_text_16":{"attribute_name":"研究科・専攻","attribute_value_mlt":[{"subitem_text_language":"ja","subitem_text_value":"工学専攻"}]},"item_81_version_type_24":{"attribute_name":"著者版フラグ","attribute_value_mlt":[{"subitem_version_resource":"http://purl.org/coar/version/c_970fb48d4fbd8a85","subitem_version_type":"VoR"}]},"item_access_right":{"attribute_name":"アクセス権","attribute_value_mlt":[{"subitem_access_right":"open access","subitem_access_right_uri":"http://purl.org/coar/access_right/c_abf2"}]},"item_creator":{"attribute_name":"著者","attribute_type":"creator","attribute_value_mlt":[{"creatorAffiliations":[{"affiliationNameIdentifiers":[],"affiliationNames":[{"affiliationName":""}]}],"creatorNames":[{"creatorName":"鴨志田, 麻実子","creatorNameLang":"ja"},{"creatorName":"KAMOSHIDA, Mamiko","creatorNameLang":"en"},{"creatorName":"カモシダ, マミコ","creatorNameLang":"ja-Kana"}],"familyNames":[{},{},{}],"givenNames":[{},{},{}],"nameIdentifiers":[{}]}]},"item_files":{"attribute_name":"ファイル情報","attribute_type":"file","attribute_value_mlt":[{"accessrole":"open_date","date":[{"dateType":"Available","dateValue":"2021-06-23"}],"displaytype":"detail","filename":"A465.pdf","filesize":[{"value":"10.7 MB"}],"format":"application/pdf","licensetype":"license_note","mimetype":"application/pdf","url":{"label":"A465","objectType":"fulltext","url":"https://muroran-it.repo.nii.ac.jp/record/10451/files/A465.pdf"},"version_id":"1538f1e5-9e6d-4b23-bf29-bf318909bc49"},{"accessrole":"open_date","date":[{"dateType":"Available","dateValue":"2021-06-23"}],"displaytype":"detail","filename":"A465_summary.pdf","filesize":[{"value":"230.8 kB"}],"format":"application/pdf","licensetype":"license_note","mimetype":"application/pdf","url":{"label":"A465_summary","objectType":"abstract","url":"https://muroran-it.repo.nii.ac.jp/record/10451/files/A465_summary.pdf"},"version_id":"78abdbd2-66ad-43ac-aafb-1f8a5a53525c"}]},"item_language":{"attribute_name":"言語","attribute_value_mlt":[{"subitem_language":"jpn"}]},"item_resource_type":{"attribute_name":"資源タイプ","attribute_value_mlt":[{"resourcetype":"doctoral thesis","resourceuri":"http://purl.org/coar/resource_type/c_db06"}]},"item_title":"水害時の高齢者施設における階上への垂直避難に関する研究－引きずり避難方法を用いた避難介助－","item_titles":{"attribute_name":"タイトル","attribute_value_mlt":[{"subitem_title":"水害時の高齢者施設における階上への垂直避難に関する研究－引きずり避難方法を用いた避難介助－","subitem_title_language":"ja"}]},"item_type_id":"81","owner":"18","path":["227"],"pubdate":{"attribute_name":"PubDate","attribute_value":"2021-06-23"},"publish_date":"2021-06-23","publish_status":"0","recid":"10451","relation_version_is_last":true,"title":["水害時の高齢者施設における階上への垂直避難に関する研究－引きずり避難方法を用いた避難介助－"],"weko_creator_id":"18","weko_shared_id":-1},"updated":"2024-01-22T02:00:52.513999+00:00"}
