Rotate while expanding or contracting by the same magnitude and the trajectory becomes a spiral. Rotating using the golden ratio of a square is basically drafting. Rotate while expanding the external angle of the circumcenter of various fractional regular polygons by the golden ratio connects the trajectory of the arc. Comparison with the logarithmic spiral generated from drafting, confirmed an external angle of close to the golden angle of about 137.5°, demonstrating the best balanced effect of 8/3 cornered polygon and 13/5 cornered polygon displaying the inverted Fibonacci sequence for the denominator/numerator. The logarithmic spiral can expressed by the formula r = e0.20051θ, and the angles of the lines connecting to the center of the spiral were about 78.7°. The system and issues related to fractal design written about in past papers are discussed. In this study, the author tried to investigate the creators skillfully applied and modified the logarithmic spiral in an experimental fashion to express the creators` intentions in own works which would be designed as the whole composition partially and or is mentioned taking the logarithm spiral expressed by the formula r = e0.20051θ for instance. It is hoped that the predicted effect of this expression will be applied and used in design for construction and interiors.","subitem_description_type":"Abstract"}]},"item_10002_heading_23":{"attribute_name":"見出し","attribute_value_mlt":[{"subitem_heading_banner_headline":"情報メディア学科","subitem_heading_language":"ja"},{"subitem_heading_banner_headline":"Department of Media and Information","subitem_heading_language":"en"}]},"item_10002_identifier_registration":{"attribute_name":"ID登録","attribute_value_mlt":[{"subitem_identifier_reg_text":"10.20832/00000232","subitem_identifier_reg_type":"JaLC"}]},"item_10002_publisher_8":{"attribute_name":"出版者","attribute_value_mlt":[{"subitem_publisher":"梅花女子大学文化表現学部"}]},"item_10002_source_id_11":{"attribute_name":"書誌レコードID","attribute_value_mlt":[{"subitem_source_identifier":"AA12749671","subitem_source_identifier_type":"NCID"}]},"item_10002_source_id_9":{"attribute_name":"ISSN","attribute_value_mlt":[{"subitem_source_identifier":"24320420","subitem_source_identifier_type":"ISSN"}]},"item_10002_text_24":{"attribute_name":"出版地","attribute_value_mlt":[{"subitem_text_value":"茨木 (大阪府)"}]},"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":"吉田, 美穗子"}],"nameIdentifiers":[{"nameIdentifier":"376","nameIdentifierScheme":"WEKO"}]},{"creatorNames":[{"creatorName":"YOSHIDA, Mihoko","creatorNameLang":"en"}],"nameIdentifiers":[{"nameIdentifier":"378","nameIdentifierScheme":"WEKO"}]}]},"item_files":{"attribute_name":"ファイル情報","attribute_type":"file","attribute_value_mlt":[{"accessrole":"open_date","date":[{"dateType":"Available","dateValue":"2021-03-12"}],"displaytype":"detail","filename":"bunka_017_009.pdf","filesize":[{"value":"2.4 MB"}],"format":"application/pdf","licensetype":"license_note","mimetype":"application/pdf","url":{"label":"bunka_017_009","url":"https://baika.repo.nii.ac.jp/record/249/files/bunka_017_009.pdf"},"version_id":"13aa665a-d20c-4d09-ab10-466de187367e"}]},"item_keyword":{"attribute_name":"キーワード","attribute_value_mlt":[{"subitem_subject":"分数の正多角形","subitem_subject_scheme":"Other"},{"subitem_subject":"対数螺旋","subitem_subject_scheme":"Other"},{"subitem_subject":"自己相似","subitem_subject_scheme":"Other"},{"subitem_subject":"Fractional Regular Polygon","subitem_subject_language":"en","subitem_subject_scheme":"Other"},{"subitem_subject":"Logarithmic Spiral","subitem_subject_language":"en","subitem_subject_scheme":"Other"},{"subitem_subject":"Self-Similarity","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":"芸術作品に見る対数螺旋の効果","item_titles":{"attribute_name":"タイトル","attribute_value_mlt":[{"subitem_title":"芸術作品に見る対数螺旋の効果"},{"subitem_title":"The Effects of Logarithmic Spiral in Art Works","subitem_title_language":"en"}]},"item_type_id":"10002","owner":"10","path":["99"],"pubdate":{"attribute_name":"公開日","attribute_value":"2021-03-20"},"publish_date":"2021-03-20","publish_status":"0","recid":"249","relation_version_is_last":true,"title":["芸術作品に見る対数螺旋の効果"],"weko_creator_id":"10","weko_shared_id":-1},"updated":"2023-06-20T14:30:21.692300+00:00"}
