Drawing on the data, this article elucidates the standard designs of huge keyhole tombs and classifies them by lineage.\nThe analysis of standard designs of tombs and their mutual relationships mainly focuses on the following four tumuli that were recently laser-scanned: Nakatsuyama Tumulus (Tomb of Empress Nakatsuhime) in Fujiidera City, Ōsaka Prefecture; Kamiishizu Misanzai Tumulus (Tomb of Emperor Richū) in Sakai City, Ōsaka Prefecture; Tsukuriyama Tumulus in Okayama City; and Kondagobyōyama Tumulus (Tomb of Emperor Ōjin) in Habikino City, Ōsaka Prefecture. Their standard designs are examined in detail, mainly by comparing computer-modeled images and survey maps.\nIn order to determine which unit of measurement was used for standard designs, we measure the length between the center of the round rear portion and the point P where the vertical axis of the tomb is intersected by the ridge lines connecting the corners of the steps in the quadrangular front portion. This is the most reliable method because the locations of these points can be determined with a minimum discrepancy. Moreover, when the edge of the burial mound is ambiguous, the radius of the round rear portion can be easily estimated from the length between the two points, which is often 1.5 times longer than the radius of the round portion.\nUsing the above-mentioned method, this study reveals the following five facts: (1) the unit of measurement for length is bu, and the angle was determined by the ratio of the base to the height of a right-angled triangle; (2) the widths of the stepped terraces were determined in multiples of 0.5 bu, which were the basic unit of measurement, although it usually varied between the quadrangular front and round rear portions; (3) because standard designs hardly met the requirements of those who placed the order, modifications were added in the actual designing process (e.g. extending the length of the burial mound); (4) each tumulus was built based on a new standard design, rather than existing ones; and (5) standard designs were passed down within the same lineage though they grew in complexity.","subitem_description_type":"Abstract"}]},"item_10002_heading_23":{"attribute_name":"見出し","attribute_value_mlt":[{"subitem_heading_banner_headline":"[共同研究] 古代東アジアにおける倭世界の実態","subitem_heading_language":"ja"},{"subitem_heading_banner_headline":"[Collaborative Research] Real Image of the World of Wa in East Asia","subitem_heading_language":"en"}]},"item_10002_publisher_8":{"attribute_name":"出版者","attribute_value_mlt":[{"subitem_publisher":"国立歴史民俗博物館","subitem_publisher_language":"ja"}]},"item_10002_relation_17":{"attribute_name":"関連サイト","attribute_value_mlt":[{"subitem_relation_name":[{"subitem_relation_name_text":"第211集 収録論文 タイトルリスト"}],"subitem_relation_type_id":{"subitem_relation_type_id_text":"https://www.rekihaku.ac.jp/outline/publication/ronbun/ronbun9/index.html#no211","subitem_relation_type_select":"URI"}}]},"item_10002_source_id_11":{"attribute_name":"書誌レコードID","attribute_value_mlt":[{"subitem_source_identifier":"AN00377607","subitem_source_identifier_type":"NCID"}]},"item_10002_source_id_9":{"attribute_name":"ISSN","attribute_value_mlt":[{"subitem_source_identifier":"0286-7400","subitem_source_identifier_type":"PISSN"}]},"item_10002_version_type_20":{"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_creator":{"attribute_name":"著者","attribute_type":"creator","attribute_value_mlt":[{"creatorNames":[{"creatorName":"新納, 泉","creatorNameLang":"ja"},{"creatorName":"ニイロ, イズミ","creatorNameLang":"ja-Kana"}],"nameIdentifiers":[{}]},{"creatorNames":[{"creatorName":"Niiro, Izumi","creatorNameLang":"en"}],"nameIdentifiers":[{}]}]},"item_files":{"attribute_name":"ファイル情報","attribute_type":"file","attribute_value_mlt":[{"accessrole":"open_date","date":[{"dateType":"Available","dateValue":"2019-03-29"}],"displaytype":"detail","filename":"kenkyuhokoku_211_03.pdf","filesize":[{"value":"782.2 kB"}],"format":"application/pdf","licensetype":"license_note","mimetype":"application/pdf","url":{"label":"kenkyuhokoku_211_03.pdf","url":"https://rekihaku.repo.nii.ac.jp/record/2412/files/kenkyuhokoku_211_03.pdf"},"version_id":"ce44579c-060d-45fd-9d52-62209735e20e"}]},"item_keyword":{"attribute_name":"キーワード","attribute_value_mlt":[{"subitem_subject":"前方後円墳","subitem_subject_scheme":"Other"},{"subitem_subject":"設計原理","subitem_subject_scheme":"Other"},{"subitem_subject":"レーザー計測","subitem_subject_scheme":"Other"},{"subitem_subject":"尺度","subitem_subject_scheme":"Other"},{"subitem_subject":"Keyhole-shaped burial mound","subitem_subject_language":"en","subitem_subject_scheme":"Other"},{"subitem_subject":"standard design","subitem_subject_language":"en","subitem_subject_scheme":"Other"},{"subitem_subject":"laser metrology","subitem_subject_language":"en","subitem_subject_scheme":"Other"},{"subitem_subject":"linear measure","subitem_subject_language":"en","subitem_subject_scheme":"Other"}]},"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":"departmental bulletin paper","resourceuri":"http://purl.org/coar/resource_type/c_6501"}]},"item_title":"前方後円墳の設計原理と墳丘大型化のプロセス (第1部　倭王権の実態)","item_titles":{"attribute_name":"タイトル","attribute_value_mlt":[{"subitem_title":"前方後円墳の設計原理と墳丘大型化のプロセス (第1部　倭王権の実態)","subitem_title_language":"ja"},{"subitem_title":"Construction Design of the Keyhole-shaped Burial Mounds and the Process of Increase in their Size (Part I)","subitem_title_language":"en"}]},"item_type_id":"10002","owner":"3","path":["236"],"pubdate":{"attribute_name":"PubDate","attribute_value":"2019-03-29"},"publish_date":"2019-03-29","publish_status":"0","recid":"2412","relation_version_is_last":true,"title":["前方後円墳の設計原理と墳丘大型化のプロセス (第1部　倭王権の実態)"],"weko_creator_id":"3","weko_shared_id":-1},"updated":"2023-07-26T00:52:40.701468+00:00"}
