區域技術知識網絡與創新之研究 / The study of the typology of regional technology knowledge network and innovation許秋惠, Hsu,Chiu Hui Unknown Date (has links)
製藥產業是高度依賴研究發展之產業,因此技術知識網絡在製藥產業中相當活躍,製藥產業因技術的突破,又可分為傳統製藥與生技醫藥兩個分支。本研究旨在探討我國製藥產業技術知識網路與創新績效之關係,透過文獻之探討,以社會網絡理論之觀點切入,利用網絡分析工具UCINET計算出廠商網絡中心性,藉由網絡中心性的分析與評估,尋找出台灣地區製藥產業技術知識網絡中的關鍵行動者。並且以網絡中心性來衡量個別廠商網絡關係的強弱及區分網絡的型態,研究區域內與跨區域網絡對廠商創新成效之影響。
研究結果發現,生技醫藥廠商跨區域合作互動情形愈高,對於創新績效愈有顯著性差異;傳統製藥產業則不論是區域內的合作或是跨區域的合作,皆能帶給其創新的能力,另外,不同的合作關係亦會影響其創新績效之表現,區域內的網絡較著重於直接網絡所帶來的系統性知識,而跨區域的網絡則著重於間接網絡中多樣化的知識。 / As a knowledge intensive industry, pharmaceutical industry cultivates highly active networks among firms and relative actors. Because of technology revolution, Pharmaceutical is divided into two forms: traditional Pharmaceutical and Pharmaceutical biotechnology. This paper aims to advance our understanding of the technology knowledge and innovation capacity of the pharmaceutical industry in Taiwan. We begin by reviewing literatures regarding network and network position. Using the UCINET, a useful method to describe and measure firms’ centralities in a social network, we find out the key players in Taiwan Pharmaceutical industry and offers an emprical examination by examining the geography of technology knowledge associated with innovation in Taiwan Pharmaceutical industry.
The empirical results indicate that there is a significant relationship between intra-regional knowledge and innovation performance in Pharmaceutical biotechnology industry, and both intra-regional knowledge and regional knowledge determine the innovation performance of the pharmaceutical industry. Furthermore, Results of this study indicate that a firm that occupies a central position in regional network of direct ties is more accessible to useful knowledge; in the other hand, firms can innovate successfully in intra-regional network both directly and indirectly.

由職官年表中利用循序共現樣式探勘人脈網絡 / Social network analysis from official chronology using sequential co-occurrence pattern mining宋邡熏, Song, Fang Shiun Unknown Date (has links)
在政治權力結構中,權臣與派系在其政治人物的社會網絡中扮演重要的角色。本論文研究由職官年表中探勘權臣與派系。我們提出資料探勘演算法由職官年表中探勘循序共現樣式,以探勘出政府官員官職陞貶的共現關係。接著根據所探勘出的循序共現樣式,建立官員之間的社會網絡。透過社會網絡分析中的網絡中心性與社群偵測分別探勘出權臣與派系。本論文以清康熙時期的職官年表實驗驗證。透過視覺化分析顯示本論文所提出的方法有助於歷史學者的研究。 / In a power structure, chief officials and cliques play important roles in the social network and have high influence on politics. This thesis proposes an approach of social network mining from official chronologies to discover the chief officials and the cliques. We propose and develop the algorithm to discover the sequential co-occurrence patterns from official chronologies. Then the social network is constructed based on the discovered sequential co-occurrence patterns. Chief officials are discovered by network centrality analysis while cliques are discovered by community analysis of the constructed social network. The official chronology of Kangxi Emperor is taken as an example for experiments and the visualization analysis demonstrates that the proposed methods are helpful to assist historian for historical research.

統計品管中製程能力指標決策程序之研究 / Some Decision Procedures For The Capability Index In Quality Control Process李仁棻, Lee, Ren Fen Unknown Date (has links)
製程能力指標(process capability index)常被用來評量製程能力的高低。它結合規格及製程變異於一指標,便利使用者易於了解指標的意義。
若吾人主張一製程能力大於某一定值,當同時控制型I及型II過誤,這時,臨界值(critical value)及樣本大小n即可決定。若同時存在有數個大於某一定值的製造過程,吾人欲挑選具有最大製程能力的製程,這時,我們提出一個客觀的準則來加以選擇。
本篇論文的特色是以解析法來決定臨界值及樣本大小n,並於挑選最大的製程能力時能提出一個客觀的挑選準則。
研究中發現:雖然逼近常用的統計上查表值時有些誤差,但誤差不大。故本文討論的過程中所用的方法及結論,適用於線上作業。

整合社群關係的OLAP操作推薦機制 / A Recommendation Mechanism on OLAP Operations based on Social Network陳信固, Chen, Hsin Ku Unknown Date (has links)
近幾年在金融風暴及全球競爭等影響下,企業紛紛導入商業智慧平台,提供管理階層可簡易且快速的分析各種可量化管理的關鍵指標。但在後續的推廣上,經常會因商業智慧系統提供的資訊過於豐富,造成使用者在學習階段無法有效的取得所需資訊,導致商業智慧無法發揮預期效果。本論文以使用者在商業智慧平台上的操作相似度進行分析,建立相對於實體部門的凝聚子群,且用中心性計算各節點的關聯加權,整合至所設計的推薦機制,用以提升商業智慧平台成功導入的機率。經模擬實驗的證實,在推薦機制中考慮此因素會較原始的推薦機制擁有更高的精確度。 / In recent years, enterprises are facing financial turmoil, global competition, and shortened business cycle. Under these influences, enterprises usually implement the Business Intelligence platform to help managers get the key indicators of business management quickly and easily. In the promotion stage of such Business Intelligence platforms, users usually give up using the system due to huge amount of information provided by the BI platform. They cannot intuitively obtain the required information in the early stage when they use the system. In this study, we analyze the similarity of users’ operations on the BI platform and try to establish cohesive subgroups in the corresponding organization. In addition, we also integrate the associated weighting factor calculated from the centrality measures into the recommendation mechanism to increase the probability of successful uses of BI platform. From our simulation experiments, we find that the recommendation accuracies are higher when we add the clustering result and the associated weighting factor into the recommendation mechanism.

從個人差異看商品設計美感的效果--以消費者商品美感中心性(CVPA)為例 / The influence of product design aesthetics on consumers' responses: Exploring consumers' Centrality of Visual Product Aesthetics as a moderator范勻瑄 Unknown Date (has links)
近年來大型消費性電子公司均致力發展商品外型的設計美感,試圖以具有視覺美感的商品吸引消費者的目光,以獲得更高的利潤。但本研究認為廠商在追逐商品設計美感時,也應探討消費者差異對於其美感反應的影響;以及不同商品以美感外型包裝時,對消費者的效果差異。對此,本研究以Bloch, Brunel & Arnold(2003)提出的消費者商品美感中心性(CVPA)、商品與自我一致性等概念,探討消費者對美感的心理差異,如何影響其對於商品設計美感的反應。同時並探討商品外顯性的差異,對於消費者的美感反應是否具有調節效果。
透過消費者美感中心性、商品設計美感、以及商品外顯性的2*2*2三因子實驗設計,本研究以3C商品為實驗商品,並以線上實驗的方式進行。研究結果如下:
1. 消費者重視美感的程度與商品設計美感間的一致性,會影響其對於商品設計的愉悅反應。
2. 商品呈現順序會調節不同CVPA消費者對於商品設計的愉悅、品牌興趣、自我與品牌連結、認知價值等反應。
3. 重視美感程度差異的消費者,並不會因為商品外顯性的調節而影響其美感反應。
4. 商品外顯性與商品設計美感之間具有交互效果:對於高外顯商品而言,高美感設計可有效提高消費者的認知價值,但低外顯商品若以高美感設計呈現,亦可使消費者因超乎預期的感受而倍感愉悅。
5. 消費者對於美感在認知層面的自我與品牌連結反應,會顯著受到CVPA「敏銳」面向的影響;在情感層面的美感評估、態度、愉悅等反應,則會顯著受到「價值」面向的影響;在行為層面的品牌興趣、購買意圖,則會顯著受到「反應」層面的影響。 / The role of aesthetical quality of a product has been placed much importance these years in the manufacturing industry, especially in consumer electronic industry. While developing products with aesthetical quality, it is also important to understand how consumers responded to products with high and low levels of aesthetic quality. The present study explored the moderating role of consumers’ psychological differences on their aesthetic responses, and also examined how differently they responded to products that differed on aesthetic quality and conspicuousness.
This study adopted the concept of Centrality of Visual Product Aesthetics developed by Bloch, Brunel & Arnold (2003) and drew upon the concept of self-product image consistency to explore how consumers’ aesthetic orientation influence their responses to products with high and low aesthetic design. Moreover, the influence of product differences has also been considered.
The proposed hypotheses were tested by a three-factor on-line experiment. The results are as follows:
1. The consistency of consumers’ CVPA and products’ design aesthetics influenced consumers’ pleasant feelings.
2. The order of how the stimuli were presented moderated the consistency effect mentioned above, especially on responses such as: pleasure, brand interest, self-brand connection, and perceived value toward the product.
3. For consumers with different levels of CVPA, the products’ conspicuousness did not moderate their aesthetic responses toward the product with high and low aesthetic designs.
4. There was an interaction between “product conspicuousness” and “product design aesthetics” on consumers’ “perceived value” and “pleasant feelings” toward product designs.
5. Consumers’ aesthetic responses were influenced by different dimensions of CVPA: “Acumen” accounted for significant variance in “self-brand connection,” “Value” explained significant variance in their attitudinal responses toward the product, and “Response” significantly predicted the variance in their behavioral responses.
The implications and suggestions for future studies and practitioners were also discussed.

数理的アプローチからの言語変化と外言語的要素との関わりに関する研究 / スウリテキ アプローチ カラノ ゲンゴ ヘンカ ト ガイゲンゴテキ ヨウソ トノ カカワリ ニカンスル ケンキュウ小野原 彩香, Ayaka Onohara 22 March 2014 (has links)
言語変化の原因については、比較言語学や言語地理学双方の立場から、様々な議論がなされてきたが、この問題に対し、変化の原因と変化の結果という関係を多変量的に捉えて知見を得る方法は、十分な議論があるとはいえない。そこで本研究では、これまでの言語変化の議論を踏まえつつ、具体的な事例について、系統推定や重回帰分析、対応分析といった数理的な手法を用いて多変量的な分析を行い、言語変化の原因や原因別の変化の特徴を明らかにした。 / 博士(文化情報学) / Doctor of Culture and Information Science / 同志社大学 / Doshisha University
