The Human Brain During the First Trimester 6.3 to 10.5 MM Crown-Rump (Cr) Lengths: Atlas of Human Central Nervous System Develop

為了解決cr動物的問題，作者Bayer, Shirley A.,Altman, Joseph 這樣論述：

上市體重對肉豬屠體商業分切獲利之影響

為了解決cr動物的問題，作者曾賢修 這樣論述：

依照2020台灣養豬統計手冊所述，台灣豬肉消費量每人每年為36.84 kg，為國內第二大消費肉量，且肉豬上市體重也逐年升高，統計至2020年為止，台灣上市肉豬拍賣活體重達到124.97 kg。隨著活體重的增加，其部位肉的組成亦會發生改變，而造成肉豬經分切銷售後之獲利產生變化。本試驗目的為探討不同活體重所屠宰的豬隻，其部位肉佔屠體組成的比例，並將部位肉組成重量代入零售價格加總後扣除購豬成本後計算其獲利情形。本試驗共採用499頭市場拍賣肉豬，肉豬經屠宰後收集其屠體性狀數據，並收集國內北部及南部部位肉零售價格進行分析探討。本試驗依照活體重分為五組，第一組為小於100 kg，第二組為100-110

kg，第三組為110-120 kg、第四組為120-130 kg，第五組為大於130 kg，分組後計算其屠體性狀、部位肉組成差異及部位肉重量代入零售價格時的獲利差異。結果顯示在屠體性狀方面，屠體重、屠宰率、屠體長及背脂厚度會隨著活體重增加而顯著上升(p

以自動相機估計中台灣石虎族群密度

為了解決cr動物的問題，作者顏全佑 這樣論述：

石虎（Prionailurus bengalensis）為野生動物保育法所公告之瀕臨絕種保育類野生動物，由於石虎實際族群密度資料的缺乏，難以準確估算全島石虎族群量。本研究在南投縣中寮鄉設置後寮及龍眼林等兩個各30 km2的樣區，每個樣區各有30個1 km2網格並設立1樣點，每個樣點架設兩部紅外線自動相機進行拍照及個體辨識，主要目的有四：(一)利用捕捉-再捕捉法估算兩個樣區之石虎密度；(二)評估每個樣點兩台相機比一台相機在石虎密度估計上的成效；(三)探討每個相機樣點的石虎出現頻度指數(Occurrence Index, OI)是否可反映在該樣點出沒的個體數；(四)探討電腦輔助軟體-Hotspo

tter在石虎個體辨識的應用性。結果顯示，在後寮樣區分別以非空間直觀捕捉-再捕捉法(Non-spatial capture–recapture methods, CR)及以空間直觀捕捉-再捕捉法(Spatially explicit capture–recapture methods, SECR)所估計的石虎族群密度分別為每100 km2 有55隻及49隻；龍眼林樣區分別以CR法及SECR法估計的密度為每100 km2有57.5隻及41.9隻。使用兩台自動相機之照片比起使用單一相機照片，石虎密度於後寮及龍眼林樣區分別提升11.5%及77.2%。兩個樣區內不同樣點OI值與石虎辨識量皆呈現顯著正相

關，相關係數分別為0.772及0.878。本研究發現電腦輔助軟體-Hotspotter能提供研究人員進行個體辨識之參考，但無法完全取代以人工進行個體辨識。
