Resonance reduction for linked train cars moving on multiple simply supported bridges
No full textThe dynamic interaction of a moving train over a series of railway bridges with equal spans can result in a coupled vibration problem of wave transmission between two periodic structures. Dual resonance occurs when both systems vibrate in phase and the train travels at a resonant speed. The objectives of this paper are to (1) develop an active pitching resonator (APR) to attenuate resonance waves in a train; (2) study the dispersion relation for pitching motion control of periodically linked train cars; (3) investigate the key parameters that affect the dispersion band gaps of wave attenuation in a train; (4) present an active vibration cancellation method to enhance the control performance of the APR; and (5) demonstrate the effectiveness of using the optimal APRs to reduce resonance of a moving train. Through dispersion analysis, the optimum APR can not only shift the target frequency level away from resonance of a moving train, but also create a wide resonance band gap to reduce wave transmission in the train. Finally, the effectiveness of the optimum APR unit in reducing the resonance and attenuating the waves of a train travelling over multiple-span simple beams is demonstrated by dynamic finite element analysis of the train-bridge interaction.國科會補正完畢GB
行為減碳對油品需求量的影響
No full text全球氣候變遷的加劇，促進各式各樣減少碳排放活動的推展，其中行為減碳已成為各
國政府和社會共同關注的重要議題。國內外也推動了一系列有效的減碳活動。展望未來，
各項減碳力道，將隨著更大型氣候災變的出現而更加強。本文利用一些圖表探究「行為減
碳」對油品需求量的影響。在說明廣義的行為減碳後，本文提出國內外各式行為減碳以降
低油品需求的具體作法。另外，本文也強調重大天災人禍可誘發明顯之行為減碳。中國石油協會補正完畢TW

臺灣照相館黑白相片手工上色發展：以南庄玉光照相館為例
No full text早期因攝影技術尚未成熟，照片無法以彩色的方式呈現，僅能以黑白的形式將照片保存記錄，為了使照片更符合真實，也因此自19世紀中葉出現了藉由手工上色的方式，從而讓黑白照片得以呈現色彩，雖無法完全的呈現眼睛所見真實世界的樣態，然卻可達當下人們心中所期待的顏色。黑白照片手工上色的作法在過去並不罕見，為傳統相館中常見之服務項目，然隨著彩色底片與相紙的普及，以及數位科技的進步，使得人們逐漸淡忘過去習以為常的記錄方式，甚而漠視傳統照相館上色師技術及其作品的文化價值。在這樣的背景之下，過去照相館上色師逐漸凋零，相關文獻紀錄更係闕如，也因此有系統地記錄這項即將消逝的產業記憶有其急迫與必要性。有鑑於此，本文除藉由文獻的分析與爬梳，論述黑白照片手工上色自19世紀中葉的崛起與東漸情形，並針對苗栗南庄玉光照相館負責人李湞吉進行口訪，配合相關文獻的整理，分作照片手工上色的進入市場，以及技術與學習等幾項議題，期能藉此一窺過去臺灣照相館在黑白照片手工上色之發展情形，並藉此為臺灣攝影產業留下難得的紀錄。補正完畢TW
The Colorist of Old Days: Cultural Significance of Colorizing Historical Photography by Prince Wang
No full text圖書館所典藏的歷史影像，因過去保存環境的影響，致使物件或酸化、褪色、脆裂、破損、蟲蛀，而修復實體有時因修復技術與成本上的限制，因而採取數位修復的作法，俾使降低觀閱時的影響與干擾。除了從修復的角度之外，如何促進人們對於影像內容的認識，亦成為文化典藏領域所探討的議題。近年來社會文化意識高漲，使得民眾愈發關注昔日老照片的故事與背景，對於老照片上色的接受度也相當高。本文藉由文獻分析，瞭解過去電腦自動著色技術發展及手繪數位上色技術的崛起，並針對「臺灣古寫真上色」社團及其創辦人王子碩進行訪談，以其觀點瞭解其社團成立之背景、黑白照片上色之目的與文化意義，從而探討歷史影像上色的文化意涵。補正完畢TW
我國大學校院校史館建置與管理現況調查分析
No full text本文係採用問卷法分析我國大學校院校史館建置及其經營管理現況，問卷調查重點在於瞭解各校校史館之設置與命名、行政隸屬與營運、人員與館舍、館藏與管理、數位化與加值應用等面向問題。問卷調查以普查方式，總計發放162份，回收有效問卷95 份。研究發現各校設置校史館比例僅及一半，其行政隸屬多在祕書室或圖書館之下，預算與人力資源不夠，校史館典藏與管理制度有待健全，對於校史資料檢索與展覽推廣觀念，仍待加強。根據研究結果提出我國大學校院校史館未來發展相關建議。補正完畢TW
Resolving Rank Reversal in TOPSIS: A Comprehensive Analysis of Distance Metrics and Normalization Methods
No full textThis paper examines ranking reversal (RR) in Multiple Criteria Decision Making (MCDM) using the Technique for Order of Preference by Similarity to Ideal Solution (TOPSIS). Through a mathematical analysis of min-max and max normalization techniques and distance metrics (Euclidean, Manhattan, and Chebyshev), the study explores their impact on RR, particularly when new, high-performing alternatives are introduced. This research provides insight into the causes of RR, offering a framework that clarifies when and why RR occurs. The findings help decision-makers select appropriate techniques, promoting more consistent and reliable outcomes in real-world MCDM applications.補正完畢LT
企業社會責任績效對財務風險的影響
No full textSince the UN Global Compact was proposed in 1999, entrepreneurs and institutions around the world have placed a steadily increasing emphasis on corporate social responsibility (CSR). Accompanying the increased levels of CSR reporting and activities, researchers raise questions regarding whether the aim of a firm's operations is always to maximize shareholder value regardless of other potential motivating factors, an assumption frequently stated in past literature. The present study infers that a firm with superior CSR performance experiences lower market risk and liquidity risk, from empirically assessing the effect of CSR performance on financial risk. The robustness test also finds that superior CSR performance reduces the cost of capital. Furthermore, the study documents that the performance of corporate governance activities increases the cost of capital. Although there is a positive association between corporate governance performance and the cost of capital, prior research suggests that the corporate governance dimension is distinct from other social and environmental dimensions of CSR. Therefore, if the study excludes the corporate governance dimension from CSR activities, the result supports the hypothesis that CSR performance, in sum, is negatively related to the cost of capital.補正完畢TW
