We discuss di-centric analysis, which is an estimation procedure of radiation dosage by counting number of di-centric chromosomes in cells of an exposed individual. In the di-centric analysis we have to make our own standard response curve by using learning data prior to applying test-data. The learning data are constructed by exposing cells to several fixed dosages and counting di-centric chromosomes. One of long-standing problems in di-centric analysis is whether random effects should be accounted in the analysis. In our study, we tried to dissect random effects from the counting data by using counting data constructed by using cells taken from 13 individuals. In di-centric analysis for low dosage we usually assume quadratic response curve, where Poisson intensity of counting per cell is a quadratic function of the dosage. We investigated separation of random effects and fixed effects from the estimated response curves of each individual. We adopted a Bayesian hierarchical model and estimated fixed and random effects by using MCMC. We found random effects are relatively small and thus we can expect fixed effects can be estimated precisely. Our result suggests that we have to prepare better standard response curve by estimating fixed effects by using large learning data.","subitem_description_type":"Abstract"}]},"item_10005_description_6":{"attribute_name":"会議概要（会議名, 開催地, 会期, 主催者等）","attribute_value_mlt":[{"subitem_description":"XXVIth International Biometric Conference","subitem_description_type":"Other"}]},"item_access_right":{"attribute_name":"アクセス権","attribute_value_mlt":[{"subitem_access_right":"metadata only access","subitem_access_right_uri":"http://purl.org/coar/access_right/c_14cb"}]},"item_creator":{"attribute_name":"著者","attribute_type":"creator","attribute_value_mlt":[{"creatorNames":[{"creatorName":"Mano, Shuhei"}],"nameIdentifiers":[{"nameIdentifier":"638789","nameIdentifierScheme":"WEKO"}]},{"creatorNames":[{"creatorName":"Akiyma, Miho"}],"nameIdentifiers":[{"nameIdentifier":"638790","nameIdentifierScheme":"WEKO"}]},{"creatorNames":[{"creatorName":"Hirai, Momoki"}],"nameIdentifiers":[{"nameIdentifier":"638791","nameIdentifierScheme":"WEKO"}]},{"creatorNames":[{"creatorName":"Suto, Yumiko"}],"nameIdentifiers":[{"nameIdentifier":"638792","nameIdentifierScheme":"WEKO"}]},{"creatorNames":[{"creatorName":"穐山 美穂","creatorNameLang":"en"}],"nameIdentifiers":[{"nameIdentifier":"638793","nameIdentifierScheme":"WEKO"}]},{"creatorNames":[{"creatorName":"平井 百樹","creatorNameLang":"en"}],"nameIdentifiers":[{"nameIdentifier":"638794","nameIdentifierScheme":"WEKO"}]},{"creatorNames":[{"creatorName":"數藤 由美子","creatorNameLang":"en"}],"nameIdentifiers":[{"nameIdentifier":"638795","nameIdentifierScheme":"WEKO"}]}]},"item_language":{"attribute_name":"言語","attribute_value_mlt":[{"subitem_language":"eng"}]},"item_resource_type":{"attribute_name":"資源タイプ","attribute_value_mlt":[{"resourcetype":"conference object","resourceuri":"http://purl.org/coar/resource_type/c_c94f"}]},"item_title":"RANDOM EFFECTS IN MEASUREMENT OF RADIATION EXPOSURE BY BIODOSIMETRY","item_titles":{"attribute_name":"タイトル","attribute_value_mlt":[{"subitem_title":"RANDOM EFFECTS IN MEASUREMENT OF RADIATION EXPOSURE BY BIODOSIMETRY"}]},"item_type_id":"10005","owner":"1","path":["29"],"pubdate":{"attribute_name":"公開日","attribute_value":"2012-11-09"},"publish_date":"2012-11-09","publish_status":"0","recid":"64827","relation_version_is_last":true,"title":["RANDOM EFFECTS IN MEASUREMENT OF RADIATION EXPOSURE BY BIODOSIMETRY"],"weko_creator_id":"1","weko_shared_id":-1},"updated":"2023-05-15T21:07:09.923587+00:00"}
