生活於數位時代，巨量的個人生命記憶使得人們難以輕易解讀，必須經過檢索或標籤化才可以進一步瞭解背後的意涵。本研究著力個人記憶裡繁瑣及週期性的廣泛事件，進行於「情節記憶語意化」以及「何以權衡大眾與個人資訊」兩議題之探討。透過生命記憶平台裡影像標籤自動化功能，我們以時空資訊為索引提出持續性概念重構模型，整合共同知識、個人近況以及個人偏好三項因素，模擬人們對每張照片下標籤時的認知歷程，改善其廣泛事件上註釋困難。在實驗設計上，實作大眾資訊模型、個人資訊模型以及本研究持續性概念重構模型，並招收九位受試者來剖析其認知歷程以及註釋效率。實驗結果顯示持續性概念重構模型解決了上述大眾與個人兩模型上的極限，即舊地重遊、季節性活動、非延續性活動性質以及資訊邊界註釋上的問題，因此本研究達成其個人生命記憶在廣泛事件之語意標籤自動化示範。 / In the digital era, labeling and retrieving are ways to understand the meaning behind a huge amount of lifetime archive. Foucusing on tedious and periodic general events, this study will discuss two issues: (1) the semantics of episodic memory (2) the trade-off between common and personal knowledge. Using the automatic image-tagging technique of lifelong digital archiving system, we propose the Coutinuous Reconceptualization Model which models the cognitive processing of examplar categorization based on temporal-spatial information. Integrating the common knowlegde, current personal life and hobby, the Continuous Reconceptualization Model improves the tagging efficiency. In this experiment, we compare the accuracy of cognitive modeling and tagging efficiency of the three distinct models: the common knowledge model, personal knowledge model and Coutinuous Reconceptualization Model. Nine participants were recruited to label the photos. The results show that the Continous Reconceptualization Model overcomes the limitations inherent in other models, including the auto-tagging problems of modeling certain situations, such as re-visiting places, seasonal activities, noncontinuous activities and information boundary. Consequently, the Continuous Reconceptualization Model demonstrated the efficiency of the automatic image-tagging technique used in the semantic labeling of the general event of personal memory.

英國女劇作家渥坦貝克(Timeberlake Wertenbaker) 筆下著名的《夜鶯之愛》 (The Love of the Nightingale) 在近年來獲得多方批評家的討論。大多數的批評家總以政治及性別的角度探討這部劇作中呈現女性如何成為男性暴力下的受害者。然而，本論文將採用德勒茲 (Gilles Deleuze) 和瓜塔里 (Félix Guattari) 的去疆域化 (deterritorialization)、生成動物 (becoming-animal)、再疆域化 (reterritorialization)、及少數文學 (the minor literature) 的理論概念，重新剖析渥坦貝克如何透過翻譯 (translation)、互文性 (intertextuality)、變形 (transformation) 書寫等寫作策略，彰顯普洛克涅 (Procne) 及菲勒美拉 (Philomele) 如何在受盡錯置及語言喪失的苦痛後，找到越界的可能性。在德勒茲和瓜塔里的理論架構之下，本論文的第一章節將先詮釋普洛克涅及菲勒美拉如何離開父系體制，並藉由逃逸路線 (lines of flight) 展開去疆域化的旅程，並在去疆域化的過程中面臨到未知的危險及機會。再者，論文中也探討普洛克涅及菲勒美拉的動物變形可以被視為她們僭越傳統意識型態束縛的証據。在經歷過生成動物 (becoming-animal) 的過程之後，普洛克涅及菲勒美拉改變了她們對於原生社會及世界的態度及看法。最後，普洛克涅及菲勒美拉的再疆域化帶領她們到另一個新的疆界，釋放女性內心的忿怒及慾望。在新的疆域中，女性們發現到另一個新的出口，重新探索流動性主體的存在，挑戰有機體式的國家體制。 / Timberlake Wertenbaker’s The Love of the Nightingale (1989) is the preeminent play of translation which calls many critics’s attention. Based on the myth of Procne and Philomele, The Love of the Nightingale is always discussed by critics from the political and sexual perspectives to show how women become the powerless victims under the male violence. However, in this thesis, I would like to use Deleuze and Guattari’s concepts of deterritorializaion, becoming-animal, and reterritorialization to analyze how Procne and Philomele find out the possibility of transgression from the suffering dislocation and dispossession of language through Wertenbaker’s dramaturgy of translation, intertextuality, and transformation. Applying Deleuze’s and Guattari’s theories to analyze The Love of the Nightingale, I would first show how Procne and Philomele obtain the chances to leave the patriarchical territory, beginning their deterritorialization to encounter unknown risks and chances via lines of flight. After the deterritorialization, Procne’s and Philomele’s physical metamorphosis could be regarded as the evidence of how they traverse the presupposed ideological system. In the process of becoming-animal, Procne and Philomele change their attitudes and perspectives toward their cultures and the world. Later, they are reterritorialized to another territory, releasing their desire and anger. In the new territory, they could find another way to search fluid identities and to challenge the state apparatus.

本篇論文的目的在介紹階層貝氏之時間與空間統計模式(spatio-temporal model)，將此模式應用在疾病地圖的分析，以了解疾病在空間上的分佈狀態與時間趨勢。模型中除了納入時間、空間和年齡的效應外，也包括時間與空間、時間與年齡的交互作用，並考慮到空間相關性(spatial correlation)，然後以DIC值(Deviance information criterion)作為模式選取的準則。 本文並以民國88-90年全身紅斑性狼瘡的女性患病人數做為實證分析的資料。配適時間與空間統計模式後，以馬可夫鏈蒙地卡羅法(MCMC)來模擬參數值，估計出各時間、地區、年齡層的對數疾病發生率。由疾病地圖可看出，台灣地區全身紅斑性狼瘡的女性疾病發生率，以20-59歲的年齡層發生率較高，0-19歲的發生率較低。不管在哪一個年齡層，北部和中部地區的發生率都是最高的。時間趨勢方面，88-90年整體疾病發生率有遞減的趨勢，60歲以上的發生率也是遞減的趨勢。但在部分地區，則有發生率遞增的趨勢。 / In this study, we introduce the spatio-temporal model in a hierarchical Bayesian framework and use disease maps to display the spatial patterns and the temporal trends of disease. A special feature of the model is the inclusion of spatial correlations used to examine spatial effects relative to both regional and regional changes over time by group. Then, we use deviance information criterion (DIC) to compare complex hierarchical models. The methodology is illustrated by an analysis of female Systemic Lupls Erythematosus (SLE) morbidity data in Taiwan during the period 1999-2001.The model inference is implemented using Markov chain Monte Carlo method. The outcomes of the practical analysis appear that the higher morbidity rate occurs in 20-year and 40-year period. No matter what age group, the morbidity rate is highest in the north and the middle of Taiwan. Furthermore, the morbidity rate decreases with respect to year as well as over the 60-year period but it increases in some places.

本研究以貝氏網路作為表示教學領域中各個學習觀念的關係的語言。教學領域中的學習觀念包含了基本觀念與綜合觀念，綜合觀念是由兩個以上的基本觀念所衍生出來的觀念，而綜合觀念的學習歷程即為學生在學習的過程中如何整合這些基本觀念的過程。了解綜合觀念的學習歷程可以幫助教師及出題者了解學生的學習路徑，並修改其教學或出題的方針，以期能提供適性化的教學及測驗。為了從考生答題資料中尋找出這個隱藏的綜合觀念學習歷程，我們提出一套以mutual information以及一套以chi-square test所發展出來的研究方法，希望能夠藉由一個模擬環境中模擬考生的答題資料來猜測考生學習綜合觀念的學習歷程。 初步的實驗結果顯示出，在一些特殊的條件假設下，我們的方法有不錯的機會找到暗藏在模擬系統中的學習歷程。因此我們進而嘗試提出一個策略來尋找較大規模結構中的學習歷程，利用搜尋的概念嘗試是否能較有效率的尋找出學生對於綜合觀念學習歷程。雖然在實驗中並沒有十分理想的結果，但是在實驗的過程中，我們除了發現學生答題資料的模糊程度為系統的正確率的主要挑戰之外，另外也發現了學生類別與觀念能力之間的關係也是影響實驗結果的主要因素。透過我們的方法，雖然不能完美的找出學生對於任何綜合觀念的綜合歷程，但是我們的實驗過程與結果也對隱藏的真實歷程結構提供了不少線索。 最後，我們探討如何藉由觀察學生接受測驗的結果來分類不同學習程度與狀況的學生之相關問題與技術。我們利用最近鄰居分類法與k-means分群法以及基於這些方法所變化出的方法，探討是否能透過學生的答題資料有效的分辨學生能力的類別。實驗結果顯示出，在每個觀念擁有多道測驗試題的情況下，利用最近鄰居分類法與k-means分群法以及基於這些方法所變化出的方法，藉由考生答題資料來進行學生能力類別的分類可以得到不錯的正確率。我們希望這些探討和結果能對適性化教學作出一些貢獻。 / In this thesis, I employ Bayesian networks to represent relations between concepts in pedagogical domains. We consider basic concepts, and composite concepts that are integrated from the basic ones. The learning processes of composite concepts are the ways how students integrate the basic concepts to form the composite concepts. Information about the learning processes can help teachers know the learning paths of students and revise their teaching methods so that teachers can provide adaptive course contents and assessments. In order to find out the latent learning processes based on students’ item response patterns, I propose two methods: a mutual information-based approach and a chi-square test-stimulated heuristics, and examine the ideas in a simulated environment. Results of some preliminary experiments showed that the proposed methods offered satisfactory performance under some particular conditions. Hence, I went a step further to propose a search method that tried to find out the learning process of larger structures in a more efficient way. Although the experimental results for the search method were not very satisfactory, we would find that both the uncertainty included by the students’ item response patterns and the relations between student groups and concepts substantially influenced the performance achieved by the proposed methods. Although the proposed methods did not find out the learning processes perfectly, the experimental processes and results indeed had the potential to provide information about the latent learning processes. Finally, I attempted to classify students’ competence according to their item response patterns. I used the nearest neighbor algorithm, the k-means algorithm, and some variations of these two algorithms to classify students’ competence patterns. Experimental results showed that the more the test items used in the assessment, the higher the accuracy of classification we could obtain. I hope that these experimental results can make contributions towards adaptive learning.

本文以貝氏方法估計方向距離函數，加入單調性與曲度限制，同時考慮環境變數於模型中。為了凸顯考慮非意欲產出方向距離函數的優點，本文同時估計產出面射線距離函數，並與方向距離函數模型比較。實證分析資料為1970至2010年間各國總體經濟變數，分別在有無加入限制條件與環境變數的狀況下，估計兩種距離函數，從無效率值、效率分數與技術進步率等角度分析彼此間的差異。發現射線距離函數模型由於忽略非意欲產出，傾向高估生產單位的技術效率。另一方面，其係數估計值容易違反射線距離函數的先天性質，較不具參考性。而方向距離函數模型當中，有無加入限制條件與有無考慮環境變數的模型結果各不相同，其中同時加入限制條件與環境變數的模型結果最為合理。

在製作動畫上，模擬人體的運動一直是困難的課題；但在如線上遊戲等急速成長的虛擬環境應用中，人物運動的動畫常是不可或缺的一環。過去在此方面的相關研究雖然為數不少，但大多數的系統皆只適用於某特定的地形或事先給定的腳步落點；能根據地形特徵而自動產生對應之行走運動者並不常見。本論文提議的系統，便是一個能即時模擬人體走路動作的運動計劃器。我們以反向關節運動的方式，分析人體在不平路面上行走時的運動特徵，並以貝茲曲線表示懸浮腿的運動軌跡。透過貝茲曲線控制點的調整，可以讓下半身的肢體避免碰觸到凸起的路面。其次，此系統也包含了腳步計劃的機制，讓虛擬人物能以行進效率為準則，計劃未來數步內保證可行的步伐。再者，我們根據實際測量的資料與觀察，找出行進過程中每個階段在時間分配上的差異，並利用製作動畫的原理，加入緩入與緩出的概念，以調整行走步伐的節奏，使動畫更具真實感。最後，我們將此模擬系統套用於「線上模擬」與「即時操控」兩種不同模式的應用系統，以驗證此系統之即時性與實用性。 / Simulating human motion has been an important and challenging topic in computer graphics for many years, especially after the booming of virtual environment applications such as on-line games. Although there has been much research on this topic, most previous systems are only capable of generating a realistic locomotion for a set of given footsteps on a flat ground in an off-line manner. The system we propose in this thesis is a lower-body motion simulator for humanoid capable of planning efficient footsteps and automatically generating collision-free locomotion in real time. First, we observe and analyze the motion characteristics of human walking and use Bézier curves to represent the trajectory of a floating leg during a stride. We use an inverse kinematics approach to compute the corresponding joint angles for a given leg trajectory. By adjusting the control points of the curve, we can change its shape to avoid collisions with the ground. Second, the system also includes a footstep planner that can generate successful and efficient gaits over an uneven terrain with an empirical energy consumption model. Third, according to observation and measured data, we use the “ease-in” and “ease-out” techniques and appropriate timing for each phase of a walking cycle to generate more realistic motions. Finally, we have applied this motion simulator to a virtual environment system with two types of operation modes: on-line simulation and real-time navigation which are verified the efficiency and practicability of such a system.

在二十一世紀中，節能已成為一個重要的議題，而在眾多的節能產品之中發光二極體的發展更是為全世界所注意。本研究有鑑於台灣於發光二極體產業之產值目前已經居於全球第二名，僅次於第一名的日本，嚐試進一步分析台灣於LED產業的技術面以及管理面有何優缺點，並試圖給予進一步的建議。本研究依據發光二極體的產業鏈位置、公司成立時間以及規模等因素挑選了四間具有代表性的公司進行個案公司的相關專利佈局分析以及探討。在本研究最後的研究結論分別針對市場面、技術面以及智慧財產經營管理面做出結論，研究中發現多數廠商有事業策略落後專利佈局以及佈局範圍不夠廣泛的問題。而相對於以上所提及之研究結論，本研究也進一步做出建議：在公司的研究發展方面應做到智慧財產的同步化、將智慧財產的概念體現於公司的組織定位中以及加強研發人員的教育訓練；在技術方面，台灣廠商應積極加入制定相關標準的組織，並在接受國外廠商授權時更要積極的同步建立自主技術及專利以提升技術層次，強化自身競爭力；在策略運用方面，台灣廠商應避免將智慧財產窄化成法律的議題、善用策略聯盟跳脫傳統代工的思維、積極的部屬而非消極的跟隨、以合作的思維替代競爭的思維以及注意分散風險的概念。 / The Light Emitting Diode (LED) has become the center of attentions from industries worldwide due to its performance in energy conservation. The value share of Taiwan’s LED industry has achieved a supreme degree only second to that of Japan. This thesis aims to analyze the merits and shortages of technical and management field of LED industries in Taiwan and to provide further suggestions. The research selects four representative companies as case studies of their patent strategies, The selection criteria includes the company’s position in the industrial chain, the age and the business scale. The thesis ascertains a fact that most industries’ patent strategy is usually restricted and falls behind their business plan. This thesis suggests the synchronization and realization of intellectual property in the R&D through organization assemble and personnel training. Taiwan industries should expand the content of IP management other than legal issues, well utilize strategic alliance, transcend old-fashioned OEM management thinking, adopt the role of an active agent instead of a passive follower, collaboration instead of competition, and pay attention to diversification.
