The paper reviews studies on the environment concerning relative humidity in small spaces such as packing cases, storage boxes, and display cases. A large number of measurements for packing cases are focused on just a constant relative humidity before 1970's, and afterwards the concern moved to a constant moisture content of the cultural property. When packing cases are hermetically sealed against moisture diffusion and air exchange, the interior temperature of the cases is influenced by the variation of the ambient temperature. A rise in temperature causes a rise in relative humidity and vice versa. The ratio is ⊿H/⊿T= 0.4 in the case which contains cellulosic materials such as wood and paper. It is the smaller amount of moisture in the air relative to the content that causes this phenomenon.\nSome papers pointed out wooden storage boxes regulate relative humidity variation effectively. It depends on the construction, thickness of the wood, and the ratio of interior surface against interior volume of the box. Within well constructed traditional boxes, relative humidity variation is reduced to less than 10% of the ambient daily periodical change, and to less than 20% of the weekly periodical change. However, over a seasonal periodical change, there is no such reduction.\nThe interior relative humidity of display cases is influenced by the ambient relative humidity. The main cause of relative humidity variations constructed of metal and grass cases is air convection, related to the air exchange rate of the case. Relative humidity variation is controlled by better sealing the cases and by introducing moisture buffering materials in the cases. M values of moisture buffering materials introduced into the display cases are easily affected by the air exchange rates of display cases.","subitem_description_type":"Abstract"}]},"item_10002_identifier_registration":{"attribute_name":"ID登録","attribute_value_mlt":[{"subitem_identifier_reg_text":"10.15024/00000838","subitem_identifier_reg_type":"JaLC"}]},"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76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/ronbun4/index.html#no76","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":"神庭, 信幸","creatorNameLang":"ja"},{"creatorName":"カンバ, ノブユキ","creatorNameLang":"ja-Kana"}],"nameIdentifiers":[{}]},{"creatorNames":[{"creatorName":"Kamba, Nobuyuki","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":"2016-04-01"}],"displaytype":"detail","filename":"kenkyuhokoku_076_03.pdf","filesize":[{"value":"4.1 MB"}],"format":"application/pdf","licensetype":"license_note","mimetype":"application/pdf","url":{"label":"kenkyuhokoku_076_03.pdf","url":"https://rekihaku.repo.nii.ac.jp/record/855/files/kenkyuhokoku_076_03.pdf"},"version_id":"5138e426-5ada-4327-98e0-43f2a488063a"}]},"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":"博物館における相対湿度環境に関する研究動向(1)小空間の特性","item_titles":{"attribute_name":"タイトル","attribute_value_mlt":[{"subitem_title":"博物館における相対湿度環境に関する研究動向(1)小空間の特性","subitem_title_language":"ja"},{"subitem_title":"Review of Studies on the Environment of Relative Humidity in Museums (1)","subitem_title_language":"en"}]},"item_type_id":"10002","owner":"3","path":["105"],"pubdate":{"attribute_name":"PubDate","attribute_value":"2016-04-01"},"publish_date":"2016-04-01","publish_status":"0","recid":"855","relation_version_is_last":true,"title":["博物館における相対湿度環境に関する研究動向(1)小空間の特性"],"weko_creator_id":"3","weko_shared_id":-1},"updated":"2023-08-25T04:30:34.903955+00:00"}
