從永續理念探討老樹保護之立法

隨著道路網絡之串聯與民生公共工程的興建，老樹的生存環境遭受到人為加速的破壞，讓諸多聳立於鄉野的百年老樹，或漸漸枯萎、或迅速死亡。基於永續發展之理念，若不加速立法保護，這些寶貴的綠色文化資產，將從我們的土地上消失無蹤。當前老樹生存所面臨的問題包括生育地受限、不當移植、病蟲害、人為破壞、依附植物、雷擊與風襲，當務之急便是透過立法程序給予老樹適當法定地位，依照相關法令對全國之老樹加強管理工作

Adopting Web Feed and Agent Technologies for Supporting Asynchronous Web Interactions and Constructing E-Commerce Applications

隨著電子商務的發展以及網路經濟的起飛，越來越多的使用者除了使用網際網路(Internet)取得 所需的資訊外，亦開始透過各式手持裝置進行多樣化的網路交易(如：Amazon/Yahoo!/淘寶網線上 購物、Apple iTunes/App Store 線上數位內容…等等)而獲取各形式之資訊、產品及服務。在使用者進 行網路交易的過程中，若電子商務的服務因為伺服器軟硬體故障或網路連線問題而導致服務中斷， 原可取得的訂單將隨之消失，亦無法取得消費者的信任。本研究以網路供餵技術為基礎，搭配代理 人的使用設計出一套能夠應用在可攜式裝置上，並具有使用簡單、高度可用性、輕量化，可用以支 援非同步式網路互動之電子商務容錯服務架構。採用此架構可以改善企業服務並提高電子商務網站 的彈性及可用性，讓企業把握住每一個可能的交易機會。With the continuous development of e-commerce and Internet economy, more and more people not only obtain necessary information through the Internet but also adopt various portable devices to conduct online transactions (such as Amazon/Yahoo!/Alibaba online shopping, Apple iTunes App Store, etc.) to acquire various information, products, and services. However, if the service is interrupted due to any server or network connectivity or availability problems while performing online transaction tasks, an e-commerce website might lose business opportunities and even their customers’ trust. The main purpose of this study is to utilize the Web Feed technology together with agent technology to design a simple, highly available, and light weight e-commerce fault tolerant service architecture applicable in a multimodal pervasive environment for supporting asynchronous Web interactions. This framework may be utilized to enhance enterprise services and improve the flexibility and availability of e-commerce websites, thus retaining more business opportunities

Integration and Application of a Fiber-Optic Sensing System for Monitoring Debris Flows

This study presents an innovative fiber-optic sensing system for monitoring debris flows. The system mainly comprises an interrogator and four fiber Bragg grating accelerometers. The field tests show that signal-to-noise-ratio (SNR) of the fiber-optic sensor is 10 dB higher than that of a geophone. Following confirmation of the reliability of the proposed sensing system, the systems are deployed along the Ai-Yu-Zi and Chu-Shui Creeks in Nautou County, Taiwan, for monitoring debris flows. The four accelerometers are installed in series. The systems have detected several debris flows in 2012. The monitored data reveal that the frequency range of the acceleration of ground vibration is 10-150 Hz, which is the same as that of the velocity of ground vibration detected by a sensing system that includes geophones. Because the fiber-optic sensing system is more sensitive than the geophone system, the proposed fiber-optic sensing system is highly promising for use in monitoring natural disasters that generate ground vibrations.本研究藉由組合光纖光柵加速度計、解調儀、及其他相關元件，發展一套可偵測土 石流之光纖感測系統。現地測試結果顯示，與目前常用含地聲檢知器的土石流感測系統相較， 本系統所測得地表振動訊號之訊雜比比前者高10 dB。在測試系統量測效能後，將此系統分別 架設於南投縣信義鄉神木村之愛玉子溪及出水溪上。系統中採串連方式配置四個光纖加速度 計，並於2012 年監測到多場土石流。觀測結果顯示，光纖感測系統所測得土石流所造成地表 振動之加速度，與過去地聲檢知器所測得土石流地表振動速度，兩者頻率一樣，均為10–150 Hz。由於光纖光柵加速度計相較於地聲檢知器更為靈敏，因此，除了可應用於偵測土石流外， 也可應用於監測會產生地表振動的其他坡地災害，如：落石及山崩等

Silver Metallization of Polyimide Surfaces Using EnvironmentallyFriendly Reducing Agents

Two environmentally friendly reducing agents, ascorbic acid and glucose, were employed to fabricate Ag-thin-film-coated polyimide(PI) films. Ascorbic acid is an acidic reducing agent, whereas glucose is an alkaline reducing agent. Both of these reducing agentsare capable of reducing Ag+ ions doped in poly(amic acid) (PAA) formed by hydrolysis of a PI surface. Only glucose can producea continuous and dense Ag thin film on a PAA surface. Granular and discontinuous Ag thin films were obtained when ascorbic acidwas employed as a reducing agent. This difference in reactivity is attributed to the pH values of these reducing solutions

Aggregation induced photodynamic therapy enhancement based on linear and nonlinear excited FRET of fluorescent organic nanoparticles

A binary molecule can self-assemble to form fluorescent organic nanoparticles (FONs) based on the Aggregation-Induced Emission Enhancement (AIEE) property and subsequently, presents an efficient fluorescence resonance energy transfer (FRET) to generate singlet oxygen under linear and nonlinear light sources. Biologically, this FON-photosensitizer is much more phototoxic to cancer cells than to normal cells without significant dark toxicity. Eventually, a new approach, called FON FRET-PDT or AIEE FRET-PDT, to promote the PDT effect is expected
