「台灣的代工製造產業應該如何發展」的問題，是困擾PC產業的管理難題，特別是在公司面臨產品成熟、訂單驟減、毛利下滑的時刻。所有台灣的代工製造產業亟思轉型的方法和方向，但是轉型到的新的產品市場或產品也是非常複雜、動態、多重因素多相互依存及影響。屬於複雜難解的問題(Wicked Problem)、問題本身都還需要定義及釐清。本論文將列出想解決的議題並定義為服務設計的議題。 因此本研究的服務設計議題(Service Design Challenge)可定義如下:「以服務設計思維建構專業代工緯創的未來」。本論文經由訪談傳統PC產業的品牌公司、IC供應商、作業系統公司和工業PC的公司，研究過程藉由運用服務設計(Service Design)手法並發掘洞見(Insights)與價值，據此將真正符合客戶需求，在找出表面及深層需求後、設計新的服務模式，得到其反饋之後再修正設計；接著結合最新科技趨勢，例如：物聯網、工業4.0、感測器和機器手臂，以提供客戶安心的代工服務；最後希望藉由改變運營模式，達到緯創成功轉型的目標。 雖然新的科技尚未成熟，只要方向正確，這些模式或能力成熟後，可以快速讓公司保持彈性，能充分利用的資源，進行個別化差異設計。 / “How to develop the ODM (Original Design Manufacturer) industry in Taiwan” is plagued by PC industry management problems, especially for those companies facing product maturity, orders plummeted and the decline in gross margin. The ODM in Taiwan is trying to change the way and direction, but the transition to the new product market or product is very complex, dynamic and involves multiple inter-dependent factors. It is a complex problem (Wicked Problem), and the problem itself also needs to be defined and clarified. The aim of this thesis is to address and define the issues through the lens of service design. Therefore, our Service Design Challenge Problems can be defined as: “The Future of Wistron through the Service Design Lens". This thesis, through interviews with traditional PC industry brand companies, IC suppliers, operating systems companies and industrial PC companies, adopts the research process of the service design approach and explores the insights and value, which will truly meet Customer needs, identify the surface and deep demand, attain the design of new service model, and integrate the latest technology trends, such as Internet of things, industry 4.0, the sensor and the robot arm, in order to provide customers with reliable and assured ODM services. Our final hope is to change the operating mode and achieve a successful Enterprise Transformation of Wistron. Although the new technology is not yet mature, as long as the direction is correct in light of these models or abilities to mature, the company can remain flexible, make full use of resources, and create individualized design differences.

Growth and development are central constituents of the human experience. Although the American Psychological Association aims to understand change and behavior in ways that embrace all aspects of experience (APA, 2008), sudden, life-altering or quantum transformation has been disregarded throughout the history of psychology until recently (see Miller & C' de Baca, 1994, 2001). Quantum transformation is similar to self-surrender conversion (James, 1902), but different from peak experiences (Maslow, 1964) and near death experiences (Lorimer, 1990) because quantum transformation, by definition, involves lasting change. Quantum transformation contains epistemic qualities, which refer to the content and process of knowing (Miller & C' de Baca, 2001), but little is known about these qualities. The current study employed a qualitative method to better understand the epistemic qualities of quantum transformation. Fourteen participants were extensively interviewed about their experience. Analysis involved hermeneutic methods (Kvale, 1996) and phenomenological description (Giorgi & Giorgi, 2003). Quantum transformation is essentially a process of knowing that unfolded in the form of Disintegration, Insight, and Integration in the present study. First, Disintegration is presented by themes of Overwhelming stress, Relational struggle, Hopelessness, Holding-on, Control, Psychological turmoil, Self-discrepancy, and Guilt. Second, Insight is presented by the Content and Tacit knowing of the experience. Third, Integration is presented by Changes in values, Other-orientation, and A process of development. The results suggest that the disintegration and the suffering that characterizes the pre-transformation milieu inform how quantum transformation relates to lasting change. Therapists that automatically aim to alleviate moral-emotional sorrow or guilt should consider whether the emotional experience can bring about positive transformation. Overall, quantum transformation has potentially major implications for our understanding of personality change and moral development.

The accumulated mucus in the sinuses is one of the areas of interest that have not yet been implemented methods for the calculation of volume and area. In the present scenario, the patient monitoring is done visually, depending largely on perception of the evaluator. Therefore, we seek to implement more accurate metrics to facilitate medical care to the patient and it can help prevent the worsening of rhinitis in a given patient, developing mechanisms of visual and numerical comparison, where it is possible observe the progress of treatment. This work contains a detailed study of how certain existing techniques, combined into one methodology can segment and calculate the accumulated mucus in the maxillary sinus. In addition to techniques such as Thresholding, Gaussian filter, Mathematical Morphology, Metallic Artifacts Reduction during processing and segmentation, MUNC and DTA to calculate the volume and area, and visualization techniques as the Marching Cubes, it was also necessary some adjustments in the algorithm for limit the region of interest where the thresholding combined with the gaussian filter has not been effective of retaining edges. The application will use two open source platforms, one for processing, ITK, and another for visualization, VTK. The results demonstrated that it is possible to perform segmentation and the calculation with the use of platforms as well as the methodology used is adequate to solve this problem. / Os seios paranasais são importantes objetos de estudo para o diagnóstico de rinossinusites, tendo alguns estudos relacionado a incidência de asma na fase adulta a quadros de rinite alérgica na infância. Muitas aplicações atendem a diversas partes do corpo humano, obtendo de entrada uma tomografia computadorizada ou ressonância magnética, e devolvendo, muitas vezes, números que dizem respeito ao objeto de interesse observado, como volume e área. O muco acumulado nos seios paranasais é uma das regiões de interesse que ainda não tiveram métodos implementados para o cálculo do volume e área. No cenário atual, o acompanhamento do paciente é feito de forma visual, dependendo muito da percepção do avaliador. Portanto, busca-se a implementação de métricas mais precisas para facilitar o acompanhamento médico ao paciente e ajudar na prevenção do agravamento de um quadro de rinite em um determinado paciente, criando mecanismos de comparação visual e numérica, onde é possível observar a evolução do tratamento. Este trabalho contém um estudo detalhado de como determinadas técnicas existentes, combinadas em uma metodologia, podem segmentar e calcular o muco acumulado nos seios paranasais maxilares. Além de técnicas como a Binarizacão, Filtro Gaussiano, Morfologia Matemática, Redução de Ruídos Metálico durante o processamento e segmentação, MUNC e DTA para o cálculo do volume e área, e técnicas de visualização como o Marching Cubes, foram necessários também ajustes no algoritmo para limitar a área segmentada onde a binarizacão combinada ao filtro não foi capaz de manter as bordas da região de interesse. A aplicação fará uso de duas plataformas de código livre, sendo uma para o processamento, ITK, e outra para visualização de imagens, VTK. Os resultados demonstraram que é possível realizar a segmentação e o cálculo com o uso das plataformas, bem como a metodologia empregada é adequada a resolução deste problema.

重要性（Materiality ）是審計過程中一個極重要但又很模糊不清的觀念。一方面審 計人員必須依據重要性來作專業判斷，但是另一方面又沒有任何準則來指導重要性判 斷。因此，審計判斷的品質經常良莠不齊，而投資大眾對查帳報告的信心也大為降低 。就因為這個綠故，所以研究審計重要性判斷成為一件刻不容緩的事情。 本論文採用Brunswik的透視模型（Lens Model）來研究重要性判斷。研究對象為某大 學會計系四年級的６０位學生，研究內容包括：（１）要求這６０位學生根據３個線 索（Cue ）來判斷一項存貨沖銷事件是否重要（這３個線索分別是該沖銷金額對淨利 百分比、對存貨百分比、以及對總資產百分比）；（２）研究這６０位學生的重要性 判斷策略（Judgment Policy ，使用統計ANOVA 與ω□）以及判斷的品質（Judgment Quality ，使用Stability 、Self-insight、與Consensus 三個指標）；（３）研究 穩定性（Stability ）、自我洞查力（Self-insight）、一致性（Consensus ）三者 之間的關係。 研究結果顯示學生的穩定性、自我洞查力、一致性均很低（其總平均分別為：．３９ ９７、．２０５０、．３８６９），而且個別差異很大（其標準差分別為：．４００ ８、．７３６９、．１８４８）。至於三個指標之間的關係也並不明確（穩定性與自 我洞查力、一致性的相關係數分別為：．０１９５、．２７４２，而自我洞查力與一 致性則為．０１０４）。

本研究旨在探討審計人員對薪資內部控制制度的判斷行為，經由透視模型的應用，以 描述審計人員的判斷政策，同時透過審計人員自我洞察力、判斷穩定性及判斷共識性 的測試，以衡量其判斷的品質。期能經此實證研究，增進對國內審計人員從事審計判 斷能力的了解。 另外，本研究並希望能找出可能影響審計判斷品質的因素，以謀可能的增進判斷品質 之道。因此，本研究同時也測試了職級及事務所規模對判斷品質的影響，以及自我洞 察力和判斷穩定性及判斷共識性間的關係。 本研究為人類資訊處理研究在審計方面的應用，因此在文獻探討中，對美國學界在人 類資訊處理方面的研究加以簡介，並對國內、國外相關的審計判斷實證研究作一彙整 。 本研究的受試者，係以隨機抽樣方式產生，包括大型事務所兩家及中型事務所五家之 各職級審計人員，共計６０員。問卷包括四大部份，第一部份為合夥人同意函及研究 簡介，第二部份為個案中虛擬公司的背景資料，第三部份為３２個薪資內部，控制個 案及６個用以測試穩定性的重複個案，請求受試者評估其內部控制制度的強弱，最後 並詢問其在判斷過程中對每個衡量因素倚重的程度，第四部份為個人資料。搜集之實 證資料經由電腦軟體程式處理。 本研究的實證資料顯示：國內審計人員的內部控制制度判斷，和美國一系列相關研究 的結果對照，國內審計人員在這方面的能力不遜於美國的審計人員。另外除共識性外 ，未發現職級或事務所規模對審計判斷品質有重大影響。

En observant le foisonnement de métaphores de la lumière et de la vision dans l’œuvre de Reinaldo Arenas – l’accentuation de la couleur, l’éblouissement, la brûlure et le dédoublement – cette thèse s’interroge sur la vision de l’écriture formulée dans et à partir de ces images, et sur les implications de cette vision. Constatant à travers cette réflexion l’inscription à même le langage des images de la lumière et de la vision – de la réflexion à la clarté, en passant par l’image et la lucidité – cette thèse délibère, à travers l’œuvre de Reinaldo Arenas et celle de Jorge Luis Borges, sur une définition de l’écriture comme intensité, notion et image empruntées au registre du sensible par le détour de la physique. Le premier chapitre s’intéresse à la couleur comme phénomène de la vision, du sensible, de l’affect et de la nuance, ainsi qu’à la métaphore de la cécité abordée par Borges et par Paul de Man comme phénomène de la lecture, points d’entrée à une réflexion sur l’écriture. Le second chapitre aborde la notion d’éblouissement en tant qu’intensité de la lumière et temporalité de la prise de conscience lucide, définissant ainsi une vision du temps et les affinités entre la temporalité de l’écriture et celle de l’image poétique. Le troisième chapitre, réitérant la question de la relation au temps – historique et narratif –, réaffirme les inflexions du langage en fonction de la lumière, c’est-à-dire la relation entre l’aspect « lumineux » du langage, l’intensité de la lumière et l’intensité de l’écriture (entendue comme écriture littéraire), en explorant le seuil (la destruction par le feu) mis en lumière par l’image du phénix, figure mythique et littéraire de la transformation des images, selon la définition de l’imagination proposée par Gaston Bachelard. Enfin, la double conclusion (une conclusion en deux parties, ou deux conclusions réfléchies l’une dans l’autre), relie les images poétiques de la lumière évoquées et leurs implications en examinant la portée d’une vision de l’écriture comme intensité. Cette idée est élaborée à travers l’image finale du double, figure littéraire constitutive et omniprésente à la fois chez Arenas et chez Borges, image non seulement de la relation entre le personnage et son double (qui relève de l’hallucination ou de l’imagination, images, encore une fois, de la vision), mais aussi de la relation entre l’auteur et le texte, le lecteur et le texte, l’écriture et le temps. La double conclusion vise le dédoublement et redoublement comme figures de l’intensité dans l’écriture. Le lien entre la vision métaphorique et l’écriture comme intensité est donc articulé par la métaphore, telle qu’entendue par Borges, élargie à l’image poétique dans la perspective de Gaston Bachelard ; elle s’appuie sur la vision de la littérature pensée et écrite par Arenas. La réflexion est double : dans le texte et sur le texte, au plan poétique et au plan d’une réflexion sur l’écriture d’Arenas ; sur l’écriture et, implicitement, sur la littérature. / Plunging into the work of Cuban writer Reinaldo Arenas, this thesis examines the connection between Arenas’ exuberant choice of metaphors related to light and vision – such as color, dazzle, fire, the double – and the potential meanings and implications of a narrative strategy based on such images. By underlining the persistence, within language itself, of images related to light and vision – such as reflection, clarity, lucidity and illumination –, as well as by examining the work of Reinaldo Arenas as well as of Jorge Luis Borges, this thesis offers a definition of writing as an experience characterized by intensity. The first chapter analyzes how color as a visual phenomenon relates to the emotional realm and to the senses, as well as to their nuances ; following which, it exposes the metaphor of blindness within the experience of reading, as evoked by Borges and Paul de Man, leading to a reflection on writing. The second chapter deals with the notion of dazzle as being, at once, a visual experience, and the very moment of awareness, thus reflecting on the concept of time, and on the understanding of writing, although perceived as linear, as grounded in a temporality similar to that of the poetic image. The third chapter expands on the notion of a relationship between historical time, fictional time, narration, and light, emphasis being placed on the parallel between light intensity and narrative intensity, based on the “igniting” origins of language. Drawing on Gaston Bachelard’s definition of imagination, it discusses the notion of threshold (where ignition leads to destruction) symbolized by the Phoenix, a mythical and literary figure of the transformation of images. Finally, the two-fold conclusion (a double conclusion or two reflecting conclusions) brings together the metaphors related to light that have been discussed in the previous chapters within the perspective of writing as an experience characterized by intensity. Through the metaphor of the double that pervades and informs Arenas’ as well as Borges’ works, the relational and double nature of narration comes to life at the intersection between the character and his doubles (also an effect of vision as a creation of imagination or hallucination), between the author’s expression and the reader’s interpretation, between literature and time. The metaphors related to doubling recurring in Arenas’ work offer a sense of intensification which summons up a vision of writing characterized by intensity. Thus, the connection between poetic thinking and narration is established through a metaphor, as defined by Borges and expanded through Gaston Bachelard’s notion of poetic imagery, and it is grounded in Reinaldo Arenas’ constant play between formal expression and narrative content. Implicit is a double reflection, on literature and time.

Nous étudions la faisabilité du procédé de distillation extractive continue pour séparer des mélanges azéotropiques A-B à température de bulle minimale ou maximale, avec un tiers corps E lourd ou léger. Les mélanges ternaires A-B-E appartiennent aux classes 1.0-1-a et 1.0-2 qui se subdivisent chacune en deux souscas selon la position de la courbe d'univolatilité. La colonne de distillation a trois sections, rectification, extractive, épuisement. Nous établissons les équations décrivant les profiles de composition liquide dans chaque section en fonction des paramètres opératoires: pureté et taux de récupération du distillat, taux de reflux ratio R et rapport des débits d'alimentation FE/F dans le cas d'un tiers corps lourd ; pureté et taux de récupération du produit de pied, taux de rebouillage S et rapport des débits d'alimentation FE/F dans le cas d'un tiers corps léger. Avec un tiers corps lourd alimenté comme liquide bouillant au dessus de l'étage d'alimentation du mélange A-B, nous identifions le distillat atteignable et les plages de valeurs faisables des paramètres R et FE/F à partir du critère général de faisabilité énoncé par Rodriguez-Donis et al. (Ind. Eng. Chem. Res, 2009, 48(7), 3544–3559). Pour la classe 1.0-1a, il existe des rapport FE/F et reflux ratio minimum. Le rapport FE/F est plus important pour le procédé continu que pour le procédé discontinu parce que la faisabilité du procédé continu nécessite que les profils d'épuisement et extractifs s'intersectent. Pour la classe 1.0-2, les deux constituants A et B sont des distillats potentiels, l'un sous réserve que le rapport FE/F reste inférieur à une valeur limite maximale. Le procédé continu exhibe également une valeur minimale de FE/F à un taux de reflux ratio donné, contrairement au procédé discontinu. Avec un tiers corps léger alimenté comme vapeur saturante sous l'étage d'alimentation du mélange A-B, nous identifions le produit de pied atteignable et les plages de valeurs faisables des paramètres S et FE/F à partir du critère général de faisabilité énoncé par Rodriguez-Donis et al. (Ind. Eng. Chem. Res, 2012, 51, 4643–4660). Comparé au cas des tiers corps lourds, le produit principal est obtenu en pied. Autrement, les comportements des classes 1.0-1a et 1.0-2 sont analogues entre les tiers corps léger et lourd. Avec un tiers corps léger, le procédé continu ajoute la contrainte que les profils de rectification et extractifs s'intersectent. La contrainte d'intersection des profils d'épuisement et extractif est partagée par les deux modes opératoires continu et discontinu. Ce travail valide la méthodologie proposée pour évaluer la faisabilité du procédé de distillation extractive continue et permet de comparer les tiers entre eux en termes de taux de reflux ratio minimum et de rapport de débit d'alimentation minimal / We study the continuous extractive distillation of minimum and maximum boiling azeotropic mixtures A-B with a heavy or a light entrainer E, intending to assess its feasibility based on thermodynamic insights. The ternary mixtures belong to the common 1.0-1a and 1.0-2 class ternary diagrams, each with two sub-cases depending on the univolatility line location. The column has three sections, rectifying, extractive and stripping. Differential equations are derived for each section composition, depending on operating parameters: distillate product purity and recovery, reflux ratio R and entrainer – feed flow rate ratio FE/F for the heavy case; bottom product purity and recovery, reboil ratio and entrainer – feed flow rate ratio for the light entrainer case. For the case with a heavy entrainer fed as a boiling liquid above the main feed, the feasible product and operating parameters R and FE/F ranges are assessed under infinite reflux ratio conditions by using the general feasibility criterion enounced by Rodriguez-Donis et al. (Ind. Eng. Chem. Res, 2009, 48(7), 3544–3559). For the 1.0-1a class, there exists a minimum entrainer - feed flow rate ratio to recover the product, and also a minimum reflux ratio. The minimum entrainer - feed flow rate ratio is higher for the continuous process than for the batch because of the additional requirement in continuous mode that the stripping profile intersects with the extractive profile. For the 1.0-2 class both A and B can be distillated. For one of them there exists a maximum entrainer - feed flow rate ratio. The continuous process also has a minimum entrainer - feed flow rate ratio limit for a given feasible reflux ratio. For the case with a light entrainer fed as saturated vapor below the main feed, the feasible product and operating parameters S and FE/F ranges are assessed under infinite reflux ratio conditions by using the general feasibility criterion enounced by Rodriguez-Donis et al. (Ind. Eng. Chem. Res, 2012, 51, 4643–4660), Compared to the heavy entrainer case, the main product is removed from the column bottom. Similar results are obtained for the 1.0-1a and 1.0-2 class mixtures whether the entrainer is light or heavy. With a light entrainer, the batch insight about the process feasibility holds for the stripping and extractive sections. Now, an additional constraint in continuous mode comes from the necessary intersection between the rectifying and the extractive sections. This work validates the proposed methodology for assessing the feasibility of continuous extractive distillation processes and enables to compare entrainers in terms of minimum reflux ratio and minimum entrainer feed flow rate ratio

Syftet med denna studie har varit att undersöka vilka faktorer och motiv som ligger till grund för en missbrukares beslut att söka vård och behandling. Vidare har syftet varit att undersöka om beslutet grundar sig på individens egen insikt om sin problematik eller om det är ett resultat av omgivningens och nätverkets krav. Studien var av fenomenologisk karaktär då vi hade för avsikt att studera vad det är som gör beslutet till vad det är, d.v.s. finna essensen i vad det är som påverkar och samspelar med beslutet. För att uppnå syftet har vi använt oss av kvalitativ metod med en abduktiv ansats. Vi har intervjuat åtta före detta missbrukare och intervjuerna har varit av semi-strukturerad karaktär. De analysverktyg som användes i studien var motivation, handlingsteori, beslutsfattande samt samhällets och nätverkets påverkan på individen. Dessa användes mot bakgrund av att motivation ofta används som begrepp inom narkomanvård och missbruksforskning. Handlingsteorin och beslutsfattande har använts då vår avsikt var att betrakta ”att sluta missbruka” som en handling, men också som ett beslut. Vidare har samhällets utveckling medfört ett paradigmskifte inom narkomanvården varför vi anser att det är av relevans att beakta samhällets påverkan i studier av missbrukare. I resultatet framkom att före detta missbrukare huvudsakligen grundade sitt beslut att sluta missbruka utifrån den egna insikten om att missbruket föranledde ett eskalerande av negativa konsekvenser samt försämrad psykisk hälsa. Beslutet att sluta missbruka påverkades i olika omfattning av yttre omständigheter i form av respondenternas nätverk, sociala instanser och en önskan om att leva enligt samhälleliga värderingar. / The purpose of this study has been to examine what factors and motives that form the basis for drug users' decisions to seek care and treatment. An additional purpose has been to examine whether the decision is based on the individual's own understanding of their problems or if it is a result of ambient and network requirements. Thus, the study have been of phenomenological nature as we intended to study what it is that makes the decision for what it is, that is, find the essence of what affects and interacts with the decision. To achieve that purpose, we have used a qualitative method with an abductive approach. We have interviewed eight former addicts and the interviews were of semi-structured nature. The analytical tools that have been used in the study are motivation, action theory, decision making, society and the network's impact on the individual. These have been used with the light of that motivation often is used as a concept in drug rehabilitation and addiction research. Action theory and decision making have been used as our intent has been to consider "to quit abusing" as an act, but also a decision. Furthermore, the development of society has brought out a paradigm shift in drug services which is why we believe it is relevant to consider society's impact in studies of drug users. The results showed that former addicts mainly based their decision to quit abusing by the individual's own insight of that the abuse led to an escalation of negative consequences, and poorer mental health. The decision to quit the abuse was affected by different degrees of external factors in terms of respondents' networks, social services and a desire to live according to societal values.
