畜牧業以綠能生態循環模式在大陸的經營發展研究 - 中華綠能公司個案為例

劉哲男 Unknown Date (has links)
全球人口快速成長至七十億,且未來可能正成長到90億,糧食匱乏已是不爭的事實,若不儘快研究對策,只一味從事經濟成長是不理性的。2011年索馬利亞有30萬人餓死,全球玉米價格也上漲60 %,扣除人為因素的炒作外,耕地減少、溫度效應下欠收嚴重、養殖生畜與人爭食,都是造成糧食短缺的原因。如果能以「農產廢棄物轉換成動物日糧」、「廚餘轉換成綠能發酵飼料」的概念來研究農牧業的經營策略,比僅單方面提高農產量會來的更有效益。 因此,本研究期望能將個案的實際成果作為複製的樣板,進行完整而有效的探討,瞭解如何用最低成本來建構此模式,並運用策略為個案找到成長的機會,及如何複製到中國大陸二十五省,降低進入門檻,用有益微生物數以億萬計的優勢為人類服務,同時也為個案公司創造出新的機會及策略。 本論文以綠能發酵各種人類廢棄物之研發,營運經營管理的實際參與,對應「三化」(資源化、無害化、減量化)處理和生態循環示範基地的經驗,整理分析討論,回饋農牧業界及台灣、大陸政府回收創能政策的機構參考。

當代閱聽人研究之理論重構:試論閱聽人的思辨能力

張玉佩, Yupei Chang Unknown Date (has links)
閱聽人抗拒主流意識形態的批判能力﹐一直是閱聽人研究領域的重要議題。但是﹐現存閱聽人研究典範卻無法提出適切的討論框架﹐接收分析典範因時代變遷而使其概念模式難以適用﹐新典範如觀展/表演典範卻不關心閱聽人的抗拒問題。因此﹐本研究以閱聽人的思辨能力指稱閱聽人藉由與媒介影像互動、進而返回自我主體思考的能動性﹐試圖建構適合當代複雜媒介景象之閱聽人思辨能力的理論框架。 為了強調思考過程重於思考結果﹐本研究引入政治哲學家鄂蘭的哲學體系﹐視閱聽人的思辨能力為流動變化的過程﹐並以其提出之想像操作機制、普遍可溝通性、想像式巡訪與無家感思考狀態作為研究觀察的參考框架。於實際經驗資料蒐集分析方面﹐本研究持續觀察四年(1998年至2002年)閱聽人於《村上春樹的網路森林》發表循環文本共1,815篇﹐並從鄂蘭的哲學體系出發﹐試圖描繪閱聽人思辨進行的歷程。 研究首先發現﹐閱聽人研究應當將「閱聽人」的概念回歸到「人」的本質基礎﹐承認閱聽人並非單一、純粹、高同質性的群體﹐並重視其多元、混雜、糾結、交錯的身分認同。再者﹐閱聽人進行思辨時﹐其抗拒解構的對象不只是媒介文本蘊藏的意識形態﹐尚且包括長期自我人生經驗形成的默識與價值體系﹐因此﹐閱聽人思辨能力的呈現是綿延不斷的自我摧毀過程﹐是無所依傍與無家感心靈狀態的保持﹐唯有藉由闡述自我思考結果、與他人辯駁溝通的過程等持續的自我鍛鍊﹐才得以培育養成。

企業整體資訊有機體(EWIO)之資訊流程分析方法

李承璋 Unknown Date (has links)
在持續不斷的知識創造成為現今企業成功的主要來源時,傳統的有形資產已不足以衡量一間公司所俱有的價值,反而更應注重企業的無形資產所形成的競爭優勢。為了應付劇烈的企業競爭,企業在過去十年不斷的增加在資訊科技基礎建設及資訊系統上的投資,而現在正是要重新思考這些屬於無形資產的資訊科技相關投資價值的時候。 本研究嘗試先期的分析,基於價值鏈(Porter, 1985)的概念,利用會計交易循環為基礎,透過發展和辨識企業整體資訊有機體 ( Enterprise-Wide Information Organism, EWIO) 來透視企業整體資訊流的機制,就如同分析活生生的個體一般,來報導企業營運中所使用的企業整體資訊系統價值。 為了診斷公司的競爭優勢,我們提出這個企業整體資訊組織分析方法,來辨識、評估聯絡管道與接觸點,以及其實作。企業整體資訊組織之分析方法含有四個步驟,依序為(1)定義企業內部、外部組織圖,(2)定義關鍵性的系統表,(3)定義關鍵性的功能表,(4)定義關鍵性的實作表。 最後,我們挑選了一家製造業的公司來展現我們的研究成果。 / When the continuous creation of knowledge becomes the source of the business success, the traditional tangible capital isn't affording to estimate the value of a company, in contrast, we should pay more attention to intangible capital in business competition. To cope with the intensified business competition, a firm’s spending on IT infrastructure and information systems has increased in the past decade that it is the time to retrospect on the value of the IT-related investment of intangible capital. This research attempts a preliminary analysis. Based on a value chain conceptual framework and the concept of accounting transaction cycles, we first put in perspective the mechanism of an enterprise-wide information flows through the enterprise-wide information organism (herein EWIO), an analogy of the organism of a living body, to report used by business operation via the development and identification. To diagnose a firm’s competitive advantage, it is better to have an analytic methodology to first identify all interesting linkages and points of contacts and then evaluate the practices of all these linkages and points of contact. Here we propose the EWIO analytical methodology to identify all interested linkages and points of contact, and their practices. There are four steps in the EWIO analytical methodology – (1) Identify (Inter- and Intra-) organization diagrams; (2) Identify interesting System tables; (3) Identify interesting Functionality tables; and (4) Identify interesting Practice tables. Finally, we do our method on a company of manufacturing to show the results of our research.

台灣電腦相機廠商的創新模式-以A公司為例

江炳彰 Unknown Date (has links)
台灣消費性電子產業和以往在資通訊電子產業的經驗,有極大的不同。以往廠商只要在Wintel架構下,依循主流設計發展產品,做個快速的跟隨者,只要掌握製造優勢的條件,往往就能創造硬體產品的興盛。然而,對於沒有共同平台、沒有主流設計的消費性電子產業,這些都不足為憑,只有不斷推出令人驚艷的創新產品,才是價值創造的最大根源。因此,消費性電子產品的創新,不僅來自於豐富的專業的創意,更需要仰賴極致的技術和管理開發的效率。 本研究的目的,旨在探討台灣的企業邁向消費性電子產業的產品創新模式,這種模式必須整合不同的技術、發揮想像力、提高產品開發管理能力及運用企業內外資源等要素。其中,尤以培養創新的組織文化,是企業突破窠臼的重要因素。 本研究,透過單一公司的深入分析,將其創新能力的育成,分為內部管理機制及外部技術資源的運用兩個構面,並以國際大廠做為互補性資產,將破壞性創新產品巧妙的與市場連結,而推展到消費者手上的成功經驗。在研究中,內部管理機制方面,分別探討企業內部的創新平台與組織文化;在運用外部技術資源方面,則討論技術吸收的模式與策略夥伴的幫助。最後,對創新成果做進一步的檢驗,並對此一創新模型的複製與應用提出建議,以提供業界進行消費性電子產品創新管理與發展之參考。 / There are enormous different experiences between consumer electronic industry and IT Industry in Taiwan. In the past, as long as a maker keep himself as a rapid follower under Wintel design concept and grasping the manufacturing advantages, the make normally can easily create a booming market of hardware products. However, that is not enough for the consumer electronic product as there is no standard platform or main stream to follow, thus the true value can only created by the continuous new shinning products innovation and development. Thus the innovation of consumer product is not only from the creativity, it also relies on the ultimate technology and high efficiency of product development. The purpose of this research is to investigate the innovation model of Taiwanese enterprises in consumer electronic industry. This model has to integrate the various technologies, to extend the imagination, to manage the ability for product development and to utilize the internal and external resources; especially to cultivate the creative culture is the key factor for a company. This research adapts the detailed analysis of single company, whose incubates its ability by internal management mechanism and utilization of the external technical resources. To leverage the global firm’s market power as complementary assets, promotes the disruptive innovation product to consumers. In terms of internal management mechanism, discusses the internal innovation platform and organization culture. The other hand of utilizing the external resources, discusses the ways of technical knowledge learning and the support from the strategic partners. In the end, do the further exam on the innovation results, and offer the opinion on the duplication and application for the model. This could be a reference for product innovation and management of consumer electronic industry.

公務人員退休制度附加採行節約儲蓄制度之投資策略模擬分析

王麗婷, Wang, Li-Ting Unknown Date (has links)
為使台灣公部門能利用確定提撥的概念及妥善運用投資資源,以期在減少政府負擔的情況下獲得足夠的退休所得,故本研究以所得替代率、金錢價值比及平均數-變異數比等指標來針對公務人員退撫基金附加節約儲蓄制度採行之可能與投資策略彼此運用之模擬結果加以分析,結果如下: 1. 各情境下以BH策略所得出之期末個人帳戶平均累積值表現最佳,然其具相當大的波動變異程度,投資人需承受相當大的風險。而TIPP策略之表現則與前述完全相反。 2. 若投資者採用BH策略或是採用CPPI與TIPP策略(CM策略)且欲追求較高的所得替代率,則建議採用Lifecycle(平衡型)的投資比例配置方式,加計DB制下之給付則平均可提供男(女)性約70.204%-75.204% (65.49%-70.49%)的所得替代率,而金錢價值比則為2.399(2.95)。 3. 無論投資者採用何種策略進行投資,若欲追求最小的可能變異風險,則建議採取平衡型的投資比例配置方式,加計確定給付制下之給付則平均可提供男(女)性約67.924%-72.924%(65.318%-70.318%)的所得替代率,金錢價值比則為2.6835。 本文模擬結果所得出之所得替代率平均維持於70%上下,代表若政府將可藉此制度減輕政府負擔外亦可使員工擁有一定水平的退休生活,故可採用。至於投資策略與配置方式如何取捨須依不同的投資者而定。   關鍵詞:公務人員退撫基金、確定提撥制、所得替代率、金錢價值比、Lifecycle / Abstract Because the improvement of medical technology and the structure of population is aging. It makes human worry about the living in the future. In order to enable the public servants of Taiwan to utilize the system of the Defined Contribution and to relief the pressure of fiscal, so we simulate in this article and analysis the results of simulation by using replacement rate, money’s worth ratio, and mean-variance ratio. The result is as follows: 1.When investor adopt the BH strategy in the process of investment, it will create the best replacement rate and money’s worth ratio under every situation, but it can be anticipated more uncertainty. Investors need to think thrice before they act. The TIPP strategy is opposite. 2.If investors adopt BH strategy or CPPI and TIPP strategy (CM strategy) and wanting to pursue the substituting rate of the higher income , the best selection is proposed adopting the Lifecycle (balanced) scenario, and it can offer replacement ratio about 70.204% - 75.204% (65.49% - 70.49% ) for the man (the woman ) under adding the DB system. Besides, the money’s worth rate is 2.399 (2.95). 3. If the investors want to pursue the least influence in the process of investment whatever investors adopt which strategies, the best scenario is the balanced type, and it can offer replacement ratio about 67.924%-72.924%(65.318%-70.318%) for the man (the woman) under adding the DB system. Besides, the money’s worth rate is 2.6835. The outcome of the simulation in this article is keep the replacement rate maintain about 70% equally, What is the best selection for investor that must be contingent upon different characteristics of investors. Keywords: public servants, Defined Contribution, Replacement rate, The money’s worth ratio, Lifecycle hypothesis.

以疾病為導向之醫療風險管理-以心臟冠狀動脈繞道手術為例 / Disease-oriented control of medical risks- analyzed with coronary artery bypass grafting surgery

程毅君, Cherng, Yih-Giun Unknown Date (has links)
背景與目的: 每一項疾病都有其潛在的風險,但要有效的降低死亡率及併發症發生率,必須找出關鍵性指標加以改善或預防。我們以心臟冠狀動脈繞道手術之患者為例,希望藉由統計分析的方式,找出造成死亡以及術後併發症最相關的因素,目的不只在預測,而在於防範。 研究對象與方法: 在我們的實驗設計上,風險因子分布在手術前、手術中、以及手術後三個階段,對象是某醫學中心接受心臟冠狀動脈繞道手術的220例患者。分析採用迴歸統計建立模型,其中羅吉斯迴歸中的依變數為死亡率與罹病率,線性迴歸的依變數為加護病房留置天數以及總住院日數。ROC curve亦將被建立,以判斷模型是否能區別病患是否罹病或死亡。所得資料亦計算EuroScore及其ROC曲線面積,並與歷史資料做比較。 結果: 所建立的死亡估計模型的有兩個,預測值都在97%以上,ROC曲線面積亦都超過0.96;併發症估計模型由六個變數所構成,預測率及ROC曲線面積分別為94%和0.984。加護病房留置天數及住院天數估計模型分別由八個及十三個因子來解釋,調整後的R square分別為0.527及0.6。EuroScore對死亡與併發症的預測率,分別為93.7%和82%,ROC曲線面積分別是0.864和0.797,均高於歷史文獻記錄,未來應該廣泛應用。 結論與建議: 經由適當的風險分級和危險因子分析,我們可以找出風險高低的標準和依據,了解影響死亡率與罹病率的關鍵因子是什麼,儘可能的做事前的防範與處置,希望能夠改善結果並提高手術的存活率。 EuroScore是個值得採用的預測工具,可以廣泛應用在死亡率與併發症發生率的估計,但是必須搭配風險因子的改善,才能發揮實際的功效。我們認為,體外循環時間與再次手術是最具有空間來降低死亡率與罹病率的兩個要素,有效率的控制時間、改善造成再手術的前因後果,除了死亡率與併發症發生率的下降外,還可以及早脫離對加護病房照顧的需求並減少留置的天數。

台灣失業率與犯罪關係之初探—不同模型之比較 / Exploration of the relationship between unemployment rate and crimes in Taiwan:A Comparison between Models

魏大耕 Unknown Date (has links)
在過去研究犯罪經濟學的理論文獻上,失業率對各犯罪類型的影響為正向關係,但在實証文獻上的研究發現,卻有愈來愈多的証據支持此二個變數間的負向或無關係。為了解釋上述正向與負向間相反的矛盾關係,本篇論文嘗試利用兩種模型(非參數與非參數模型)與兩種效果(機會效果與動機效果)來解釋此二變數間的關係,此亦是本論文主要貢獻。其中機會效果是用以解釋失業率與犯罪間的負向關係,動機效果則用以解釋正向關係。在非參數模型中,利用失業率為景氣循環的代理變數,發現失業率與竊盜間存在正向關係,此與大多實証研究相符;失業率則和妨害風化與殺人犯罪間呈現負向相關;失業率與傷害罪間則沒有明顯正負關係。研究亦顯示,不同的犯罪類型在不同的參數模型下,統計的顯著性亦有不同,而在不同年齡層(青少年與成年人)的犯罪模型則更與理論模型結論相符。 / According to the theoretical literature on criminal economics, unemployment rate tends to be positively correlated to all types of crimes. However, more and more empirical evidence suggests otherwise. In order to clarify the relationship, this study exploits both nonparametric and parametric models and considers two effects, including opportunity and motivation effects. The presence of the opportunity effect leads to be a negative correlation between unemployment rate and crimes, while the presence of the motivation effect gives a positive correlation. Under nonparametric model where unemployment rate is used as a proxy for business cycles, we only found that there is positive correlation between unemployment rate and robbery, while obscenity and homicide are found to be negatively correlated with unemployment rate. This is in line with most empirical studies. Little correlation evidence is found for unemployment and other types of crimes. Under parametric model, the study indicates that the statistical significance differs in models, and depends on crime variable used. We found more consistent results with theoretic models for the age groups (teenagers and adults).

張倞菱, Chang, Ching Ling Unknown Date (has links)
時尚產業快速蓬勃發展,讓其生產鏈共同製造出的環境污染,已讓我們不得不正視其嚴重性,涵括了全球大量使用農藥的棉花田、面料染色需要大量的水資源、第三世界的血汗工廠、以及大量生產的廉價服飾,人們的慾望不斷被挑起,低廉的價格讓人們得以毫不節制地不斷購買服飾,穿不到的服飾變成在第三世界被掩埋的垃圾,這些對環境的傷害和浪費的資源,已遠超過我們可以回收的資源了。時尚產業已成為繼石油之後,位居環境汙染的No.2的幫兇。當一切的美意不再,時尚產業開始省思甚麼才是真正的美好?時尚產業所創造的社會價值是甚麼? 現行「從搖籃到墳墓」(cardle-to-grave)的產品設計不僅在環境上造成傷害,也缺乏經濟效益,因此在許多方面,尋求永續性的替代方案, 發展出創新的再利用方法所帶來的利益, 將比大部分人所能想像的還要多。 本研究主要的目的在於了解並釐清通過回收再造的循環經濟理念,時尚產業的企業以創造社會價值為前提,以商業手法獲取合理利潤得以持續經營的商業模式創新。因此,在研究問題上首先將先釐清循環經濟的本質與面貌,接著探討時尚產業對環境之衝擊和影響以及永續時尚的定義和商品結構。同時,藉由國內外最新的循環經濟的商業模式創新分析,與研究者對於時尚產業運作方式的資料收集,深入剖析永續時尚如何結合消費市場變化與社會的脈絡二者合而為一的過程,以提供國內時尚產業了解國際永續時尚營銷市場的脈動與需求,以提昇開發全球永續時尚產品的能力。 並藉由研究結果提供國內時尚產業對永續時尚資訊運用上,與歐美時尚產業同步運作的速度,並統整永續時尚產業鏈的機制與系統,以期台灣時尚產業、製造業成為發展永續時尚的亞太區重心。通過研究的探討,研究者以永續時尚為核心,提出創新商業模式。以平台概念串接消費者和供應商使其為橋梁,將永續時尚資訊收集途徑系統化,並能使其資訊透明化和有提供有效環保數據,並銷售得到消費者信賴的對地球友善之商品選項,期待成為有利於雙方的商業模式。 / Due to rapid developments in the fashion industry, the transformed production chain has created high environmental impacts. There are various sources in the production processes that casued destructions to the world, for example: the use of pesticides in cotton fields, fabric dyeing consuming great amount of water resources, the use of the third world Sweatshops, and a mixture of strategies of mass-produced cheap clothing. Consumers’ desires are constantly being provoked by those low-price and fast fashion while clothes were thrown to the third world to be buried. The pace of waste generation is far more faster than the speed of material recycling. It’s time to think about values verse demages created by the fashion industry. The primary goal of this study is to understand and clarify the concept of circular economy that promotes greater resource productivity. The aim is to reduce waste and avoid pollution by promoting a sustainable fashion design model on a crowdsourcing platform. Sustainable fashion is a part of the growing design philosophy and trend of sustainability, it is to create an eco-system which can be supported indefinitely in terms of human impact on the environment and social responsibility. The system can be seen as an alternative trend against fast fashion. For these purposes, this study will clarify the relationship of circular economy and fashion industry though the primary focus has remained on improving the impacts of productive processing and material provenance. Meanwhile, the study will examine business cases of circular economy to enhance the development of sustainable fashion platform. The findings are useful for Taiwan fashion industry to strengthen their design and development of sustainable fashion to lead Asia Pacific center. The study explored the influence of sustainable fashion on aspects of design, production, marketing, and innovative business model. The proposed platform provides information and goods of sustainable fashion and builds a channel which connects suppliers and consumers.
