Identification of the water pollution sources through analysis of water quality monitoring data of Tamsui and Kao-Ping River Basin

Jiang, Dong-Xian 26 July 2010 (has links)
In this study, time series analysis and factor analysis of multivariate analysis were applied to surface water quality monitoring data sets. In order to gain a better understanding on water pollution situations and sources of different river basin, we have done some statistical analysis according to the water quality monitoring data from the database of Environmental Protection Administration Executive Yuan in the years from 2004 to 2008. The statistical analysis is based on the aforementioned contents to find the common latent factors of the water pollution and try to explain the main sources of water pollution of river basins. Specifically the water quality monitoring data of the Tamsui River and the Kao-Ping River basin are analyzed. In seriously polluted areas, from the time series results they reveal that the water quality monitoring data has significant serial correlations. Therefore we firstly use vector autoregression (VAR) model to eliminate the dynamic dependencies of data, and later perform the factor analysis for the residuals. With this analysis procedure, the resulting models and factor variables from the factor analysis, sufficiently explained water quality variables with the potential relationship between environmental pollution in the region.

閩臺海底電線與中日交涉之研究(1895-1904) / The research of the negotiations between China and Japan upon the submarine cable between Fuchow and Tamsui(1895-1904)

林於威, Lin, Yu Wei Unknown Date (has links)
本論文探討臺灣在中日締結馬關條約被割讓予日本之際,由清廷臺灣巡撫劉銘傳時期所鋪設完成的閩臺海底電線,如何讓售日本的過程。在1895年6月馬關條約規定中日兩國應於締約後的2個月時間完成臺灣之移交,然而日方全權代表樺山資紀卻突然向中方全權代表李經方提出閩臺電線一併移交日本的要求,因此展開中日交涉閩臺電線歸屬之外交問題,使得閩臺電線問題成為甲午戰後中日之間遺留下來的臺灣問題。1898年12月7日,中日訂定閩臺電線讓售合同,解決閩臺電線之歸屬問題。從此以後,閩臺電線才正式屬於日本所有。   本研究之結果發現,閩臺電線之中日交涉問題與甲午戰後東亞國際情勢之發展有密不可分的關係。例如當時居於弱勢的中國聯合英國大東電報公司與丹麥大北電報公司,讓日本無法將新得到的閩臺電線進一步向福建內陸延長,確保中國對外電報之自主權。最後就是1904年2月爆發日俄戰爭,臺灣總督府為了搶修受損的閩臺電線,不顧中國福州海關的意見,將閩臺電線修復,差點引發另一場中日糾紛。從日俄戰爭到1945年日本投降為止,以閩臺電線為中心,臺灣成為日本海外電信的樞紐據點。 / In 1895, the Qing Dynasty was forced to sign the Treaty of Shimonoseki(馬關條約) and cede Taiwan to Japan after losing the Sino-Japanese War of 1894-1895(中日甲午戰爭). According to agreement to transfer of Taiwan all question relating to the submarine cable between Fuchow and Tamsui(福州到淡水的海底電線:閩臺海底電線)are to be settled afterwards by both Government. In 12.7,1898, to signed a Convention of the submarine cable between Fuchow and Tamsui(閩臺電線讓售合同)by China and Japan, the submarine cable belonged to Japan. According to the research of the thesis, the negotiations between China and Japan upon the submarine cable between Fuchow and Tamsui correspond to the situation of North-East Asia after Sino-Japanese War of 1894-1895. Finally, from the Russo-Japanese War to Surrender of Japanese in 1945, Taiwan became the hub of Japanese Overseas telecommunications with the submarine cable between Fuchow and Tamsui.

數位圖書館學習網站之研究

李明珊, Lee, Ming-Shan Unknown Date (has links)
數位學習是透過網際網路終身學習的管道之一,透過網際網路提供數位學習,讓人們可以不受時空的限制得以在教育學習上得到數位圖書館為數位學習帶來豐富的學習素材。 本研究採用個案研究法,選擇美國國會圖書館的學習網(American Memory之Learning Page)、美國地球數位圖書館的地球系統教育(DLESE)以及我國淡水河溯源數位博物館為個案研究對象,研究目的在探討數位圖書館學習網站在教育學習的應用及其數位學習架構,包括探究數位圖書館之意涵、特色與應用、數位學習的意涵與發展、數位學習架構的要件與設計、數位圖書館學習架構之模式,並進一步對我國數位圖書館學習網站發展提出建議,最後根據研究結果提出「數位圖書館學習模式芻議」。 根據研究結果提出數位圖書館學習模式芻議,此模式可分成兩大部分,分別為數位圖書館的部分以及數位學習網站的部分。數位圖書館數位學習架構歸納十大項,根據本論文之歸納分析,將數位圖書館數位學習架構分成十大項,分別為:(1)數位圖書館特質;(2)數位館藏;(3)數位物件;(4)Metadata;(5)資訊檢索;(6)數位學習目的與特色;(7)教學系統;(8)學習系統;(9)管理系統;(10)數位學習與數位圖書館整合等。 本研究建議:(1)從事數位圖書館學習系統總體性規劃及策略,以有效整合數位資源並進行整體化建設;(2)重視數位資源之組織與互通性研究,建立全國數位圖書館聯盟管理單位;(3)擴大數位圖書館資源共享合作服務範圍,凝聚共識與團隊力,共同建立數位圖書館學習系統的功能,結合各方資源,將數位資源發揮至最大的效益;(4)由政府單位規劃中長期的數位圖書館學習系統之發展計畫,長期而持續與推動,並且培育專門的人才。 / Digital library is studied to pass on the internet network lifetime study channels, offer the digit to study through the internet network, let people not be restricted by space-time and be educating in study to receive the digital library to study for the digit bring the abundant study material. The method of case study was used, choose the Library of Congress American Memory’s Learning Page, Digital Library for Earth System Education, and the Digital Museum of Discovery of Tamsui River were used as the case research subjects. The purpose of the study is to understand the digital library studies websites and educates the application, and several in education and study structure, including probe into the meaning of the digital library, characteristic with use, several meaning of study and develop, several between important document and design, digital library to study structure study, and study website’s development and put forward the suggestion on the digital library of our country further. Then proposing the digital library study preliminary model from the result. According to the result of the study, it provided a digital library study preliminary model, this model can divide into two major parts, first parts of the digital library and second parts of studying websites respectively. Several digital libraries study structure and sum up ten great one, analyze according to the summing up of this thesis, study the structure on several of digital libraries to divide into ten great one, including: (1)Speciality of digital library; (2)The digit hall hides; (3)Digit things; (4)Metadata; (5)Information retrieval; (6)Study the purpose and characteristic in digit; (7)Tutoring system ; (8)Study the system; (9)Administrative system; (10)The digit is studied and combined etc. with the digital library. This study is proposed: (1)Engaged in digital library learn system getting overall planning and tactics, by combining several resources and carrying on whole construction effectively; (2)Pay attention to several organization of resource and general character study each other , set up national digital library alliance management unit; (3)Expand the cooperative service range of resource-sharing of digital library, condense common understanding and group's strength , set up the digital library and study the systematic function together, combine each side resource, give play to several resources to the greatest benefit; (4)The government unit plans the medium and long-term digital library and study the systematic development plan, sustain and promote for a long time, and foster special talents.
