Background: Tue Businessweek magazine proposed lists of attending doctors in medical centers and regional hospitals based on the recommendation of hospital presidents, directors and supervisors of medical societies, and surveyed doctors. The current study aims to investigate the criteria existing in Businessweek¡¦s selection and factors related to the nomination of Taiwan¡¦s best 100 doctors. Material and Method: Subjects are the 667 doctors nominated in Businessweek¡¦s ¡§100 Especially Recommended Doctors¡¨ and ¡§600 Doctor-Recommended Doctors,¡¨ published respectively on May 5th and October 3rd, 2008. Biographical data of the subjects is firstly reorganized according to such items as specialty, hospital, education, professional training, experience and current status; introduction to specialties on websites of the hospitals where the subjects serve is also taken into consideration during data reorganization. Secondly, additional social network variables, including special positions in such non-hospital and non-school institutions as societies, foundations and publishing companies, are implemented. Collected data is analyzed by means of descriptive statistics, chi-square test and logistic regression. Results: Out of the 667 doctors, the 131 ones especially recommended by Businessweek tend to either serve in northern Taiwan or have graduated from National Taiwan University. In terms of social network, ¡§directors¡¨ of a department/branch/center are 3.082 times more likely to be nominated among the 131 than those who do not have the title, while those with special positions in medical societies are 5.314 times more likely to be nominated than those without any special position. Conclusion: The physicians not only training in the medical profession, but also need to expand social network.

Dong Gang are the biggest fresh tuna market in Taiwan. This thesis deals with the social networks in Dong Gang tuna market and how they affect the tuna market in Dong Gang. This thesis finds that although Dong Gang tuna market has public auctions, the transactions and exchange of information are highly shaped by social networks, especially in the Bluefin Tuna season that starts in April and end in June. Actors use social networks to avoid risk, control prices and maintain the quality of purchase. On the other hand, the status of actors, which is highly influenced by the licenses from the state, also has significant impacts. There are two kinds of license in Dong Gang tuna market; one for domestic market and one for export. Actors with higher status buying fish firs. This research recognizes that the market is embedded in social structure of economic sociology, and explains the dual meaning of the market: entity and concept. It also points out how local social networks shape deal of market. On the other hand, the price of Japanese tuna market influences Dong Gang tuna market; in other words, the Dong Gang tuna market is part of global tuna market leading by Japan, and the state uses license to control. That is, the Dong Gang fish market consists of local social networks, but also connects with state and global tuna market.

With the popularity of the Internet and the growing trend of Web2.0, interaction and knowledge exchanges among the Internet users become active. Facebook, currently the world's most successful social networking website of Web2.0, functions as a social entertainer and further develops as a marketing business platform. In particular, many enterprises and organizations focus on operating the function of Fan Page for the purpose of marketing strategy. The research will be conducted from the users' viewpoints and the examples of consumption on Facebook and entertaining Fan Pages will be provided to investigate the specialties and functions of the website, causing the users to organize and participate in the Fan Pages, and the behaviorial motives and the gratification obtained from the process. Substantial and virtual random samplings are utilized in conducting the questionnaire survey. The result shows the obvious difference in the motives of the Fan Page participants based on various levels of education. It also verifies the critical influence of media characteristics on the participation of Fan Page. And, it helps us realize that users with different motives obtain different satisfactions through the participation of Fan Page. In the end, the research investigation can be considered as a basis of enterprise marketing strategies theoretically and practically.

Social network web sites become very popular nowadays. Users can establish connections with other users forming a social network, and quickly share information, photographs, and videos with friends. Malwares called social network worms can send text messages with malicious URLs by employing social engineering techniques. They are trying let users click malicious URL and infect users. Also, it can quickly attack others by infected user accounts in social network. By curiosity, most users click it without validation. This thesis proposes a malicious URL detection method used in Facebook wall, which used heuristic features with high classification property and machine learning algorithm, to predict the safety of URL messages. Experiments show that, the proposed approach can achieve about 96.3% of True Positive Rate, 95.4% of True Negative Rate, and 95.7% of Accuracy.

The purpose of this paper is to study underground Mark Six, which is among the most popular activities in Taiwan. Although it involves complicated financial transaction and lots of people, the deriving debt has no legal status according to principle ¡§the gamble debt is illegal¡¨ proscribed in Taiwanese civil law. This thesis focuses on how this system operates without the assurance of the legal system, which is widely believed as the foundation of modern property right. This Data were collected by in-depth interview and participant observation, including 23 interviewers in three main roles and other related actors, gamblers, brokers, bankers, and then, observing the transaction details of underground Mark Six in the illegal casino to analyze the issue specifically. This study identities three major mechanisms that maintain the operation of underground Mark Six: social Network, violence and risk Management. First, the definition of Social network is the relationship construction under the illegal Mark Six transaction. Trust and reputation, derived from the social network, protect transaction safety as a normative force. Next, the mechanism of violence is the transaction progress which judges in underworld way. Also, the mechanism of violence has the technique of evasion of law. Third, the mechanism of risk management is by different layers' actors to work on, and therefore, these actors cause the variation of transaction rule, method and restriction. In order to avoid debt quarrel, for instance, gamblers in lower layer usually decrease the risks by separating the creditor's right to different uplinks.For the brokers in the middle layer, they use a specific transaction record to insure the transaction execution. What's more is that the bankers in the top layer would control the signed Mark Six number for some specific number to prevent a horrible ¡§Hot Pack¡¨ result. I also find that recently Underground Mark Six is toward network technology, gathering with the traditional manual operation. These two executions so called ¡§Computer Operation¡¨ and ¡§Paper Operation.¡¨ Computer operation, moreover, is toward to be an institutionalization franchise, leading the Underground Mark Six to a technology operation, especially for account and managing risk.

The development of internet is creating intense competition in social network sites nowadays. How to conduct users¡¦ loyalty to social network sites gradually becomes an important issue to operate long-term social network sites. The study attempts to examine how consumers¡¦ utilitarian value, hedonic value and social value affect their loyalty. Furthermore, this study examines whether the relationship is mediated by gender difference. The model and relationship are tested and validated by using PLS and data collected from 200 people having facebook accounts in Taiwan. The results shows that loyalty is strongly affected by utilitarian value, hedonic value and social value. We also find that the difference of gender has positive influence on hedonic value and loyalty and negative influence on social value and loyalty. The implication for research and practice are also discussed.

Abstract The thinking of subverting the Internet world is ubiquitous. In Taiwan, a wave of ¡§Happy Farm¡¨ made FACEBOOK popularity soar. Community management of this site includes dynamic sharing, online chat, Club management, Fan zone, and many other online games. It also lets the application designers enrich the site content in an open way. ¡§The Facebook¡¨ operated from February 2004 to the present. Now review the Facebook site, and it¡¦s not difficult to find the design term constantly updates connotation philosophy to match up the various types of users. The study of the social networking sites shows that the ages are on the downward trend. For now, from the 13-year-old junior high school students to the general public are included. In Taiwan, ther e are 12,107,600 population using the Facebook.(101.7.5 Ministry of the Interior statistics). Taiwan¡¦s population accounts for about 23,261,747. It means half of Taiwan¡¦s population using the Facebook. The proportion is quite popular, which is an important reference for the study of nation also of information technology in Taiwan. The research focused on the junior high school students¡¦habits of using the Facebook. We also cited the junior high school teachers¡¦ observation and interviewed development applications industry to construct the overall architecture which can be used to observ how the habits influence the students¡¦ lives and know the changes brought about by the community website. The conclusion is to give parents , teachers, and the community one note about the junior highschool students¡¦ use of the community network. The results of the following four conclusions. 1. FACEBOOK is the website of the ¡§Interpersonal Community¡¨. 2. FACEBOOK advantage is high interaction, free, and diverse functions. 3.Woman users¡¦rate of response on website message is high than men¡¦s. 4. Higher grade students who use FACEBOOK have better interpersonal relations.

The objective of this research is to develop distributed approaches to optimizing network traffic. Two problems are studied, which include exploiting social networks in routing packets (coupons) to desired network nodes (users in the social network), and developing a rate based transport protocol, which will guarantee that all the flows in a network (e.g. Internet) meet a delay constraint per packet. Firstly, we will study social networks as a means of obtaining information about a system. They are increasingly seen as a means of obtaining awareness of user preferences. Such awareness could be used to target goods and services at them. We consider a general user model, wherein users could buy different numbers of goods at a marked and at a discounted price. Our first objective is to learn which users would be interested in a particular good. Second, we would like to know how much to discount these users such that the entire demand is realized, but not so much that profits are decreased. We develop algorithms for multihop forwarding of such discount coupons over an online social network, in which users forward coupons to each other in return for a reward. Coupling this idea with the implicit learning associated with backpressure routing (originally developed for multihop wireless networks), we would like to demonstrate how to realize optimal revenue. We will then propose a simpler heuristic algorithm and try to show, using simulations, that its performance approaches that of backpressure routing. As the second problem, we look at the traditional formulation of the total value of information transfer, which is a multi-commodity flow problem. Here, each data source is seen as generating a commodity along a fixed route, and the objective is to maximize the total system throughput under some concept of fairness, subject to capacity constraints of the links used. This problem is well studied under the framework of network utility maximization and has led to several different distributed congestion control schemes. However, this idea of value does not capture the fact that flows might associate value, not just with throughput, but with link-quality metrics such as packet delay, jitter and so on. The traditional congestion control problem is redefined to include individual source preferences. It is assumed that degradation in link quality seen by a flow adds up on the links it traverses, and the total utility is maximized in such a way that the quality degradation seen by each source is bounded by a value that it declares. Decoupling source-dissatisfaction and link-degradation through an ?effective capacity? variable, a distributed and provably optimal resource allocation algorithm is designed, to maximize system utility subject to these quality constraints. The applicability of our controller in different situations is illustrated, and results are supported through numerical examples.

It is not only a complicated but also long-term mission to implement the information system and system project. It involves a variety of interior and exterior problems, such as the supporting from decision management, users' resistance, conflict between departments, leadership of project members, outsourcing¡¦s cooperation, supporting of develop tools (Software & Hardware) and cooperation of supply chain. Therefore, we have defined the social network of the CIO as seven dimensions, which are CEO, users, cross dept. chiefs, MIS dept. employees, Supplies & Clients, Outsourcings & Consultant and Software/Hardware supplies. The research tries to approach the topics from the angle of observer, starting from the social network of the CIO, by case study method, to process the detailed data analysis through a great different of CIO interviews. Thus we may find out and realize the circumstance CIO may faced and the phenomenal incurred in intercourse with the others, which intends to explore that CIO faces the challenge & response while they are trying to push information system in the enterprise. We also take the perspective of Social Capital consists of three dimensions which are structural dimension, cognitive dimension and relational dimension combined as a analyzing perspective to interpret and analyze how the CIO create and take advantage of his social capital to solve problems and achieve the goal eventually. The first finding of the research is that the social network of the CIO was suitable and practicable analyzing perspective based on the three dimensions of social capital theory; secondly, the communication between the correspondents of the CIO social network and CEO is the most importance and the most difficulty as well. The enterprise culture, background, CIO network structure have the influence on intercourse benefit. It is inter-supported with the three dimensions of the social capital. We hereby hope to achieve the following progresses with the research: 1. The reference to the qualified candidate of the CIO to an enterprise. 2. Target on the managers of information management and offer them a brief and simple analyzing perspective, in order to make an accurate diagnose & analysis to the problems. 3. The enterprise could take advantage of social capital to impulse the information system, so that it may reduce information management from any cognitive difference, conflicts between interfaces and get promotion of the service quality of the information department.

This study is base on the concept of social capital to discuss the dispersion and integration of social capital in different community actions. And try to understand the elements of social capital by the survey of the residents in community action. Further more, to indicate the background, status, participation and role to community organization and activities of all residents. Also, what all can be used in community action, include human, finance and other resources. This study tries to looking for the model of dispersion and integration of social capital through the mobilization of resources in different community action. The purposes of this study are,(1) to research the model and origin of social capital in community, (2) discussing the way to get social capital by the different kind of residents, and how it make the dispersion and integration to social capital, (3) to research why the dispersed social capital integrated to community elites. For these purposes, Chi-San Town is choice to be the area for empirical survey. In the discussion of relative theory, the concepts of social capital, community action theory and social network theory will help to analysis the mobilization of social capital. Through the demand and need to public affair, the assistant network is established in the survey of 214 residents in Chi-San Town. This network is the base structure and relation of the mobilization of social capital. Furthermore, it will be used to examine the effect and degree of resources mobilization in different community actions. The assistant network of public affair can be used to observe the dispersion and integration of social capital. When community action is processing, social capital will be integrated to the elite of residents. Residents will give the resources what the community action can use to the persons who used to assist in the demand for public affair. Through this network, community action will be more efficiency. Different community action will result in different mobilization model and degree for social capital. By this way, social capital can be observed. The social capital embedded personal relationship can be used when community act and integrate to the elite of residents.
