記憶體模組產業的轉型策略-以C公司為例 / Industrial transformation strategy of Memory Module - Case of Company C

林婉菁 Unknown Date (has links)
台灣記憶體模組廠商在全球的排名及佔有率約有10%~15%,故台灣現仍為全球記憶體模組的生產重鎮,但近兩年來,我國半導體製造業有逐年下降的現象,營收表現則受到國際情勢及消費性電子產品發展的影響而出現波動;當創新產品出現並大幅成長,造成PC及NB的需求惡化,再加上國內記憶體工廠生產成本沒有競爭力,國內DRAM大廠紛紛轉型或被迫退出市場,台灣記憶體產業的榮景已不復見。 現今台灣記憶體模組廠產業大多跳脫DRAM模組單一產品,而是多元化朝MP3播放器、數位相框、外接式硬碟盒等產品布局,但消費性產品的變化快,中小型記憶體模組廠在大廠大者恆大,小則轉型或被收購合併甚至面臨關廠的命運;中小型記憶體模組產業前景又將是營運艱辛的未來。為了解記憶體模組產業之現況及未來發展前景,因此本研究將針對國內記憶體模組公司-C公司的現況作詳細的了解,並提出對未來之建議。

半導體設備測試廠商競爭策略之研究-外商在大陸之個案 / SemiTest equipment supplier competitive strategy in China : the case of a foreign firm

王緯杰, Wang, Wei Chieh Unknown Date (has links)
中國的半導體產業發展早在2000年初即由中國的半導體之父-張汝京先生創立了中芯國際半導體公司(SMIC),得到中國政府的全力支持,展開風起雲湧的半導體運動。張汝京積極的在大陸複製台灣晶圓代工模式,中國政府亦寄望於他,希望能將台灣成功的半導體產業能落實、深根至大陸。然則歷經十年的產業發展,其製程技術一直無法突破,以進入先進製程之林,也因此大陸半導體產業鏈(含封裝、測試)一直停滯、落後於台灣,只能代工技術門檻低、毛利低的晶片生產、封裝與測試。 然中國政府自金融海嘯後,改變策略,大力培植IC設計公司,從更上游始,利用台灣成熟、先進的代工技術,培養、落實在地化IC設計團隊以影響半導體產業的發展。實至今日,大陸已有超過1000家以上的設計公司投入到整個中國半導體市場、並打進全球供應鏈。兩岸半導體產業結構已悄悄的在慢慢改變中。 以本研究的T公司(個案公司)而言,為全球首屈一指的半導體專業測試商,其專業於微波通訊、數位行動、基頻、電源管理與記憶體晶片,….等等之測試,以完整的配套測試方案之整合,迅速成為全球各地的IC設計製造廠商與代工廠在晶片測試領域的重要夥伴。然而在逐漸起飛,研發實力漸增的大陸市場中,T公司卻發生了業務拓展上的問題與瓶頸。公司內部擁有的能力與價值,是公司發展和擬定策略的基礎,且是公司利潤的來源,因此如何利用公司產品的優勢、組織內部資源與能力,以提出適合于中國市場的方案策略,成為中國在地公司的「策略夥伴」是公司再創盈利與提升全球市占率的一大課題。

In this model, all classrooms belong to subject teachers instead of students of the class. It is believed that this model could help teachers teach and students learn from the results of literature review. This study examines the relationship between the using satisfaction of variation type classroom and academic self-efficacy of junior high school students in AHS of NCCU. It also examines behaviors of junior high school students in variation type classroom. There are 158 junior high school students in AHS of NCCU surveyed, the secretary and 5 assistant class leaders interviewed, and 931 person-time and 2 classrooms observed in this study. Data gathered in this study indicated the following are the other key findings in this study: 1. The planning rationale of variation type classroom in AHS of NCCU consists of the needs of teachers teaching and students learning, storage, classroom transferring, interpersonal interactions and longer class break for more interaction and smoother classroom transferring of students. 2. The junior high students’using behaviors of variation type classroom in AHS of NCCU correspond to the planning rationale of it. 3. The junior high school students in AHS of NCCU have great using satisfaction toward variation type classroom. 4. The junior high school students in AHS of NCCU have general academic self-efficacy (2.88), with higher efficacy in verbal persuasion, physiological state, and enjoyment of learning. The female junior high students have higher academic self-efficacy than the male students do. 5. There is significant mid-level correlation between the using satisfaction and academic self-efficacy of junior high school students in variation type classroom, and the higher the using satisfaction the students have, the higher their academic self-efficacy is. The major implications of this study are as follows: 1. Variation type classroom operational model is worth promoting. 2. School planner should fully consider about the ground of the school, number of classes and faculty, curricula design and needs of teachers and students when planning space and facilities of variation type classroom. 3. In the variation type classroom operational model, classrooms should be equipped with enough teaching facilities and context of subjects should be emphasized to express the strengths of this model. 4. The convenience of the routes between subject classrooms and student lockers should be considered during arrangement process of the school and in correspondence with the class schedule. 5. The school in variation type classroom should provide safe lockers and convenient facilities for stay and wait to make students move with less stuff. Longer break (15-20 minutes) could be taken into account to promote interpersonal interaction and make students’ transferring of classrooms more smoothly. 6. The school administration needs to communicate and advocate consistently with the students, their parents and the faculty about the rationale of variation type classroom. 7. The school administration could survey about the users’ using satisfaction and opinion regularly to make necessary modification of the model or space and facilities of variation type classroom.

美國量化寬鬆政策對商業銀行股價之影響- 暨資產負債表傳遞效果 / The impact of the US QE policy on commercial bank stock returns - balance sheet channel

彭仲豪, Peng, Chung Hau Unknown Date (has links)
本研究致力於探討美國聯準會(FED)實施量化寬鬆政策(QE)與否,商業銀行資產負債表對於股價的影響。本文藉由總經指標(工業生產指數、製造業採購經理人指數)、利差變數(公司債利差、10年期公司債利差),以及資產負債表變數(存款、貸款等),對商業銀行股價進行解釋。並透過量化寬鬆政策(QE)的虛擬變數,了解該政策對股價的影響,以及實施該政策是否能夠改善資產負債表變數的顯著程度和影響方向。方法上,本文採用迴歸分析的方式進行實證分析。首先,研究以總經指標以及利差變數對股價進行解釋,且期間限定為量化寬鬆政策期間,藉此確認這兩類變數對股價的影響。後續則以加入資產負債表變數、量化寬鬆(QE)虛擬變數等,並將期間延伸至15年,以進一步釐清實施量化寬鬆(QE)政策的影響。本文實證結果顯示,美國量化寬鬆政策對於商業銀行股的股價有負面影響,且活期存款對股價的影響亦為負向。 / The thesis focuses on the FED policy – Quantitative Easing (QE) and how the policy affect the S&P 500 commercial bank sub-index return. Based on past researches, the article includes macroeconomic variables (IP, PMI), term structure variables, bank balance sheet variables (deposits and loans), and a QE dummy variable. With these variables, the outcomes are generated by regression. It can be observed that with the implementation of QE policy, stock returns are negative on average. Moreover, large banks would benefit from provide more commercial loans; on the other hand, small banks would obtain a positive return by lending more consumer loans. Demand deposits are another significant variable which would have negative impact on stock returns.

共創新價值—以「政大一畝田」為例 / Thecase of NCCU's My-Farmland Project

王耀德, Wang, Yao Ter Owen Unknown Date (has links)
本研究為個案研究,以政大EMBA永續農業促進小組所創「政大一畝田」品牌專案為例,以深度訪談為研究方法,主要探討社會公民社團,如何透過策略聯盟方式,與策略夥伴為利害關係人以及社會共創新價值,並輔以相關文獻的深度分析,對農民團體策略聯盟以推廣有機農業提供具體建議。 根據農糧署2010/05發佈台灣有機認證農地共有4217公頃,僅佔所有農地的0.4%,在政府目前積極的倡導下,消費者認同與消費者支持已大幅增加,台灣的農民團體多自行組織,自產自銷,或者透過地方產銷班等,共同銷售予通路商、中盤商,但現行的銷售管道之銷量不大,又易被中盤商壓價,因此造成台灣有機小農的銷售困境。 研究者發起「政大EMBA永續農業促進小組」,透過資源分析以及環境分析,以組織內部成員之人脈資源、資金、商管知識以及服務熱忱作為基礎,再加上政大之社群資源,與農民團體合作,選定宜蘭三星行健有機合作社作為策略夥伴,推行「政大一畝田」契作稻田認養專案,建立以國內相關企業為目標客群之企業認養的銷售管道。 此公益項目增進台灣有機稻農的生計,也為認養企業與家庭提供樂活體驗、二次公益等社會企業責任的價值,更透過媒體公關行銷,使策略夥伴以及有機議題得到大眾關注,以提昇國民對有機農產的認同與支持。 / Based on the Case of NCCU's My-Farmland Project by National ChengChi University EMBA Sustainable Agriculture Promoting Organization, this paper will discuss how Non-Profit Organizations create new value of sustainability with other stakeholders by strategic alliance and offer some advice to the agricultural organization in Taiwan to promote sustainable agriculture. This paper will also provide literature review on civil society, sustainable agriculture, social enterprise and strategic alliance. According to the Council of Agriculture, the organic farmland officially recorded is 4217 hectares which only accounts for 0.4 percent of the total farmland in Taiwan. Now through the active promotion of the government, both the consumer identification and their support have increased dramatically. The agricultural organizations in Taiwan are made up almost entirely of farmers only. They produce and sell their products on their own. Their main sales channels are to wholesalers, distributors and some end consumers in low volumes. With low bargaining power, organic farmers in Taiwan have a difficult sales condition. This researcher initiated the "National Chengchi University EMBA sustainable agriculture promotion teams" to promote the Case of NCCU's My-Farmland Project through resources and environmental analysis together with the networking, capital, business management knowledge and dedicated services of the members of the NCCU or ganization, plus the community resources of the National Chengchi University. It is the goal of this project to assist the agricultural organizations in Taiwan in prospering and expanding their business. We have selected Ilan Samsung organic cooperatives as a strategic partner to promote and execute the above project and create a sales pipeline for relevant domestic enterprises as target customers. This charity project will provide Taiwan organic farmers with better lives, and also offer country life experiences for the corporations and families who join the project. Additionally, this project will allow the corporations to fulfill their corporate social responsibilities. Furthermore, with the promotion and attention through medias, this project will really increase the consumer identification and their support for the organic farmers in Taiwan.

考慮時間價值的兩階段群組訊息網路編碼的散播機制 / A two-phase network coding design for mobile time-valued group-message dissemination

劉亭侁, Liu, Ting Shen Unknown Date (has links)
現今因無線通訊技術的進步,使得人們能方便地利用智慧型裝置透過3G,4G和Wi-Fi等技術彼此溝通聊天。其中,聊天應用是最受智慧型裝置使用者歡迎的應用程式。大部分的聊天應用程式需依賴網路以達到訊息交換的目的。然而網路的頻寬是非常有限的,當使用者處在擁擠的環境中時,他們可能會面臨資源耗盡問題。此外,例如在漫遊的情況下有些使用者並沒有行動網路的存取,導致使用者無法使用聊天應用。 因此我們希望利用無線廣播傳輸的特性,開發一個應用於間歇性網路連接的聊天應用程式。然而,廣播傳輸的散播策略若沒有設計得宜,可能導致廣播風暴的問題,使得整體網路效能低落。我們研究的目標是要如何在間歇性網路增加訊息的傳輸效率。為了達成此目標,在我們的研究中考量了許多技術要求,如:訊息具有截止時間與優先權特性、多聊天室應用、傳輸效率。 我們提出了一種兩階段基於網絡編碼設計的訊息散播方法,實現在機會性社群網路中的訊息散播。網絡編碼階段,提高網路頻寬的傳輸效率,也能增加網路傳輸的可靠性;預熱階段能提升網路編碼訊息被解開的機率。最後,利用政大的真實軌跡紀錄評估我們所設計的訊息傳播方法。結果顯示,我們的方法是有效率且優於氾濫式的路由協議和一般的網絡編碼散播技術。 / Nowadays, the advancement of wireless communication technology has allowed people to use smart phones to communicate with each other more easily via 3G/4G, Wi-Fi, etc. One kind of popular mobile Apps is “chat” App. Most chat Apps rely on the Internet to exchange the messages. However, the bandwidth of network is limited in some circumstances. When users stay in the crowded environment, they will face the resource depletion problem. Besides, some people may not subscribe to any cellular network access, e.g. in roaming scenarios. Therefore, we want to develop a novel mobile Chat APP in intermittently connected networks. We utilize the characteristic of the wireless broadcast transmission. However, it may cause the broadcast storm problem without careful design. How to increase the efficiency of message delivery in such intermittently connected networks is our research goal. To achieve this, technical issues in our research involve message priority, multi-chatroom, deadline and transmission efficiency. We proposed a two-phase network coding design for message dissemination to enable the multi-hop instant messaging in Opportunistic Mobile Social Networks. The network coding phase can increase the bandwidth utility and transmission efficiency. Moreover, it can improve transmission robustness and adaptability. The warm up phase can increase the decoding probability of coded packets. Finally, we evaluated our approach with real trace data from NCCU. The results showed that our approach is effective and superior to the flooding based routing protocol and the pure network coding technique.
