隨著eeePC 百元電腦等上網載具的日益普遍，WiMAX 與 HSDPA 等隨時隨地寬頻通訊服務也正在成長，請你選定一個族群(例如早餐店老闆，檳榔零售業者，計程車駕駛等)，設計一個應用與服務模式，並說服我們為什麼這個服務會成功。
EeePC，一直在想它有什麼創新的應用，到底有什麼特別之處，會讓它變得那麼熱門，我覺得是它的價格，以平常筆電的1/4~1/3的價錢就可以買到它，一樣是台灣電子公司的專長-cost down所得到的產物，從這個角度來看，並沒有服務創意的模式，並沒有跳脫原本的電腦使用方式，頂多是讓沒錢買筆電的人，多了一次嘗試的機會，但是，大多數人還是把它當作第二台PC，因為它跟一般PC或notebook的功能還是有差距，解析度小只有800*480，電池能力也沒有增加，不過優點是，它真的很小，很輕。
那一台很小，很輕的電腦，又可以隨時上網，它能有什麼服務？而這些服務，又可以開發到新的族群。
我想到的是-可以監測健康狀況的隨身護士。
因為醫學進步，整體的年齡層往上提高，身體的狀況也需隨時注意，可以發現，醫院常常人滿為患，人們常常就來看病拿藥，浪費的許多健保資源，我想是因為不了解自己的身體狀況，有的人是一有小問題就去看病，有的人是拖到最後一個才去看病。能有類似EeePC的機器，透過身體上得感測裝置，能夠隨時間監視自己的身體狀況，儲存再EeePC的資料庫中，常常去看病的時候，透過醫生對談才能診斷，但是以口述的方法其實並不能常常詳細的描述，往往一些癌症都是最後一刻才發現，已經無法治療。透過EeePC能將自己的狀況詳細紀錄，就醫時也方便醫生詳細了解自己的狀況，可以增加看病的效率。
透過WiMAX,HSDPA更可以在遠端與醫生對談，透過高解析度WebCam，可以檢查身體的外觀否有異樣，醫生可以開放部份的時間是以遠端來看診，患者不用前往醫院排隊看診，醫生也可以在家看診，在偏遠地區的居民也可以因此受惠，透過遠端看診，藥品可以宅急配到家。
不過，需要有監測功能的EeePC，需要在家裏或衣服內埋入感測器透過無線傳輸儲存在EeePC，在衣服裡面可以有監測心跳，體溫的感測器，透過EeePC來解析身體的狀況，在馬桶可以設置尿液感測器，可以分析目前的pH值、蛋白質、潛血反應等，糖尿病、肝膽疾疾病也可以透過尿液來分析。在沙發可以裝置體重感測器，讓你可以在每次躺在沙發吃零食看電視的時候，可以先看看你的體重。
身體健康是現代人所追求的，透過與專業醫師的合作，才可以讓醫療器具更有公信力。

1. Compare the business models of Metropolitan Wi-Fi Networks in the world.
2. Read the abstracts of the full papers, and then make your comments.
Robin Kay, Developing a comprehensive metric for assessing discussion board
effectiveness, British Journal of Educational Technology, Vol 37 No5 2006. pp. 761-783
Note: You may need to stay in the IP range of CYCU to download the article.
This paper will find out a way to evaluate the discussion board. The variable are thread, location of message within thread, author (student vs. educator), subject line clarity, time of posting, response time from previous message, number of times message was read, number of words, primary purpose, message quality, difficulty level of topic, knowledge level, processing level and use of external resources. I think the hardest part is how the student find the information they want if someone had asked before. And the purpose of the discussion board should be concerned. Not only for education, but also some technology, news discussion board which may cause other variable to show up. The participants are form different career have diversity of purpose. It remains more topics for research.

1. Read the abstract of the full paper, and then make your comments.
Feng Fua, Lianghuan Liua, and Long Wang. Empirical analysis of online social networks in the age of Web 2.0, Physica A: Statistical Mechanics and its Applications Volume 387, Issues 2-3, 15 January 2008, Pages 675-684
The paper abstrat-
The growing of WWW turns another name called Web2.0, new application and way of connecting people. For example, blogs and social networking site make people communicate more easier and faster. Two of the social networking sites in China will be analyzed. They will show the networks have small-world and scale-free feature. Also, the distribution of the topological distance will be studied. The correlations between degree and degree, clustering coefficient and degree, number of page views and degree ,respectively, are discussed in the paper. This paper will show blogging network have disassortative mixing pattern and SNS is the assortative. The research and analysis of online social networks will explain the self-organizing structural characteristics.
my comments-
It's interesting that blogs and social networking site are empirical analyzed. Both are online social networks in the age of Web2.0. I think blogs want to keep the the simple and easy to write down anything. People will find the blog and share to others(blogger in google). The connection is created in comments. Social networking site is creating a connection after you registering it. And it contains more functions for interaction. For example, every visitor will be saved to make more connections.
what are assortative and disassortative mixing?

When the population of the senior increased, the design of the mobile device is also important. From my knowledge, the elderly people cannot use all the function of the cell phone that design for young people. The keypad, words in screen are too small for them.
