隨著多元智慧型設備(如智慧型手機、筆記型電腦與平板電腦)的迅速普及，以及高效能行動網路之導入，行動寬頻市場之接受度持續快速提升中。已有越來越多的智慧型手機用戶，會在移動狀態中使用各式各樣應用及網際網路服務，預計未來十年內資訊流量將成長近百倍。 然而面對行動數據傳輸量的暴增，如何利用small-cell進行行動數據傳輸量的分流，是目前全球所有電信營運商及行動網路設備供應商所面臨的一大課題。若毫無篩選規劃的廣泛建置small-cell將耗費龐大的建置維護成本(包含設備、電路、人力及維運等支出)，卻無法得到與投入成本相對應的行動數據傳輸量分流效益。 於本研究中，我們將建立一個small-cell覓點模型來有效找出真正需要分流行動數據傳輸量的地點來建置small-cell。由2010年Informa的統計資料可知，行動數據來源有住家屋內、辦公場所、交通運輸據點及公眾開放空間等四大部分。因交通運輸據點及公眾開放空間有直接較明顯的目標地點，如何精準找出住家及辦公場所亟需分流的地點為本論文研究之重點。 最後我們透過實驗並以off-load、throughput、建置成本及選點準確率等指標，驗證本研究所建立之small-cell覓點模型確實可有效找出需要分流行動數據傳輸量的地點。

我國自1996年起開始試辦綜合高中，迄今已有十餘年。試辦綜合高中的目的在於促使我國後期中等教育能在高中、高職之外，提供另一條不同的選擇進路，俾使學生得以適性發展，學得多方面的知識，達到適性教育的目標。過去國內關於綜合高中分流政策的研究，大都集中在探討綜合高中的辦學績效和實施困難，而非該政策對學生學習成就的影響之探討。有鑑於此，本研究進一步探討：（1）哪些因素會影響國中畢業生選擇就讀普通高中和綜合高中學術導向組；（2）就讀綜合高中的學生，其學生學習成就是否優於就讀一般高中或高職；（3）綜合高中的課程分流政策是否能減少教育階層化的產生。 原始資料取自臺灣教育長期追蹤資料庫（Taiwan Education Panel Survey）公開使用版中的第一波到第四波國中追蹤樣本資料，並使用傾向分數配對法（Propensity Score Matching）探討上述三個研究目的。研究結果發現：(1)控制其它相關因素之後，過去學習成就和家庭社經背景愈佳者，愈有可能就讀普通高中及綜合高中學術導向組；(2)在學生學習成就表現上，就讀綜合高中的學生並不比就讀一般高中或高職的學生來得好；(3)綜合高中分流政策和制度性分流一樣，都會產生教育階層化現象。最後，本研究說明本研究結果對綜合高中分流政策的意涵，及提出研究建議供後續研究之用。 / Since 1996, Taiwan government launched the policy of Comprehensive High School (CHS) to relax the traditional system of curriculum tracking at the level of the senior secondary education. A number of studies and on-site evaluation reports on CHS have been made. So far, these studies and reports focused on exploring the performance of comprehensive high schools and difficulties in implementation of the policy. No evaluation of the impacts of the CHS policy on student achievement has yet been done. The purpose of this study is to examine the effects of the CHS policy on students’ achievement in the upper secondary education in Taiwan. This study attempts to answer the following research questions: (1) What factors influence junior-high school graduates’ decision on attending general high schools, and the academic track in comprehensive high schools? (2) Do students enrolling in comprehensive high schools perform better academically than those enrolling in general or vocational high schools? (3) Do curriculum tracking in comprehensive high schools enhance or reduce inequality in educational achievement? Using the data from the public released core panel data of the Taiwan Education Panel Survey (TEPS) in 2001, 2003, 2005, and 2007, this study employs the method of propensity score matching (PSM) to estimate the average treatment effect of CHS policy on student achievement. All results of PSM analysis indicate that (1) all else being equal, students with higher prior student achievement and better socio-economic backgrounds have more opportunities to enroll in an academic track, including senior high schools and the academic track in comprehensive high schools, than those with lower level of prior achievement or socio-economic backgrounds; (2) for those enrolled in comprehensive high schools, there is virtually no gain in student achievement from the CHS policy; and (3) tracking in comprehensive high schools produce inequality in educational achievement, which is similar to tracking between general and vocational high schools. Finally, the present study discusses the implications of the CHS policy and suggests directions for future research.

幹細胞在組織器官再造中的價值已成共識，由幹細胞體外培養誘導的細胞、組織和器官，用於移植時可避免免疫排斥。未來，幹細胞將在組織工程領域搶盡頭采，逐步取代傳統的異體移植。因為成體幹細胞在人體內的數目通常不多，骨髓中每1 萬個到1 萬5 千個細胞才有一個造血幹細胞(hematopoietic stem cell)，必須要經過特殊的血球分離系統才能取得足夠量，目前醫界與學界所採用的血球分離儀器主要分為螢光細胞免疫分析儀(FACS)，另外，有鑑於使用者對於可攜式的需求加上半導體技術的成熟，目前還有一項全新的微導流技術被開發，因此對於幹細胞的研究，無論是胚胎幹細胞或是造血幹細胞，一個良好適用的血液分流系統都是必須而且重要的，我們也可以看見，隨著幹細胞的運用日趨廣泛，血液分流系統技術未來成長潛力更加可以預期。 本研究係採用SRI情境分析方式，透過包含學界及實務界的專家群會議，輔以腦力激盪的方法討論出關鍵決定因素與驅動力量，並以二個不確定軸面形成情境主軸，發展擴充成為情境內涵，再就各選定之情境(微導流領先，技術導向，美麗舊時光)內容進行SWOT及策略發展分析，並發展出細胞分流技術之市場及技術共同發展策略： 1. 積極推動幹細胞研究，增加市場需求。 2. 與國際同步建立儀器的確效與驗證模式，減少法規對於儀器的限制。 3. 積極推動產業的國際化，增加產業範疇 4. 積極發展奈米技術，同步提昇微小化技術與染色技術。 5. 流體與驅動技術的持續開發。 6. 光電偵測系統的研發方向。 7. 國家介入釋放舊的半導體製程技術。 關鍵字：SRI情境分析法，細胞分流技術，微導流技術，螢光細胞分析儀，情境預測，SWOT分析。 / Stem cell's value in the tissue engineering is given a new lease of life to has already become the common understanding, train the cell , tissue and organ from stem cell, can prevent the immunity from repelling when being used for transplanting. In the near future, the stem cell will rob the end to adopt in the field of tissue engineering, will replace traditional allograft to transplant progressively. Because body stem cell usually few figure having in human body, every ten thousand have a hematopoietic stem cell in the bone marrow, must pass the special cell sorting system to make enough quantity. No matter in clinical use or academic research use, fluorescence active cell sorting system is only way to separate stem cells from blood or bone marrow. For adding the maturity of the technology of the semiconductor to with the demand of the type, a brand-new cell sorting technology with micro fluidic system is developed at present, so the research to the stem cell, no matter embryo stem cell or hematopoietic stem cell, one good suitable cell sorting system must and important, we can see with application of stem cell being becoming extensive, cell sorting systematic technology grow up potentiality may it is expected future too. This research adopts SRI scenario analysis, through include academic researchers and expert groups of meeting, commercial end users, it produce the key decisive factor and drive strength to discuss so as to method that mental work agitate to complement, and with form the situation main shaft the 2 uncertain axle, development expands and becomes situation intension, selected situation content analyzed SWOT and tactics development each, erupt simultaneously and exhibit the market that the cell sorting technology and common development tactics of technology. In this research, our conclusions are as follows: 1. Actively prompt nano- technology research. 2. Actively promote stem-cell research. 3. Actively promote the research of cell's mark. 4.

本研究使用「臺灣教育長期追蹤資料庫」第二波（2003）國三與第三波（2005）高二的CP追蹤數據，採用反事實模型框架下的傾向分數配對法估計單一性別環境對臺灣高中女生選組行爲（自然組／社會組）的因果效應。使用學生進入高中前的國三資料，本研究在學生因素，家庭因素和學校、班級因素三個方面充分平衡處置組（進入女校）和控制組（進入男女合校）的樣本，使配對樣本之間除了進入女校或進入男女合校之外，在以上三個方面儘可能相等，嘗試克服觀察性數據因選擇性偏誤問題對因果效應的估計帶來的阻礙。結果顯示，在進行傾向分數配對後，處置組和控制組之間達到了很好的平衡，進入女校的女生與進入男女合班的男女合校中的女生相比，女校顯著地促進了高中女生選自然組的機率，然而該效應在數學成績水平不同的女生中存在異質性，女校顯著地促進了數學成績處於高水平的女生的選擇自然組的行爲。作爲教育分流的重要組成部分，臺灣高中生選組行爲的性別隔離長期存在，選組行爲與學生未來大學科系選擇和職業選擇關係密切，自然組中低比例的女生組成顯現出隱藏的教育機會不平等。該現象長期存在的背後因素，除了學生個人因素和學生家庭背景因素帶來的影響，本研究關注學校這一角色對高中女生選組行爲的影響。 / Based on the Taiwan Educational Panel Survey’s core panel data from wave 2 (junior high school/9th grade) and wave 3 (high school/11th grade), researcher applies the propensity score analysis in counterfactual framework to study the causal effect of single-sex schooling on high school girls’ curriculum tracking (science track or humanity track) selection. Observational data always be the obstacles of making the causal analysis because it's lacking random assignment and being under threat of selection bias and unobserved variables. Using the pretreatment variables from students in 9th grade, students in the treatment group were matched with those in control groups by the individual factors, family factors and school, classroom environment factors. After matching, students come from different groups are supposed to be relatively equivalent on all the matching variables except for attending single-sex school or not. The researcher can make suitable comparison and prediction between well-matched samples. The result shows that more girls in single-sex high schools tend to choose science track. Effect of single-sex schooling is not the same among girls with different level of math scores. It benefits girls with top math performance significantly. As an important part of the educational tracking system, alternative curriculum tracking selection in Taiwan high school is worth noteworthy. The long lasting gender segregation is closely associated with students college major as well as occupation selection and it reveals the hidden educational inequality between gender. Other than focusing on the individual and family background effect on high school girls’ curriculum tracking selection, this study highlights the school effect on it.
