The maneuver of ROV requires considerable pilot skill which is a product of physical and mental practice over a long period of time. However, with the limitations of ROV safety, the availability and high cost of deploying equipment, most of ROV pilots gain the necessary skill through on-the-job training. In this study, we developed a simulation system for ROV pilot training and mission planning. This system is implemented in C++ with the cross-platform OpenGL for 3D graphics. It equips with a scene editor allowing the user to build complex 3D geometric objects from simpler primitives. This editor allows the user to change settings of ambient light intensity, visibility, current speed, and seafloor topography for fulfilling specific training requirements. As well, the user can translate and rotate the entire 3D scene and look at it from different vantage point. Besides, this system provides the user with simple commands for mission planning. For realistically simulating the dynamic behavior of the ROV, the nonlinear hydrodynamic equations of motion of the ROV with six degrees of freedom are applied to describe its motion. Moreover, this system is built with the capability of collision detection for evaluating the collision response of ROV. During the training process, the data engine records all navigation data which can be retrieved and played after conducting a training course. The animation playback function exactly reproduces the scenario that occurs during the period of training. It presents the trainee with the opportunity to review the whole operation scenario. Besides, experiments were designed based on the Taguchi Method to study the effects of different factors on ROV pilot performance. The factors selected for evaluation include ROV trajectory display, underwater visibility, ROV positioning error, and current speed. We found that underwater visibility has the greatest influence on ROV pilot performance, next are ROV positioning error and ROV trajectory display, then the current speed. This result will be helpful in rating the level of difficulty of the training.

Owing to the environmental change, ongoing advances in internets and information technology , the time¡Bspace and mass have changed. To respond to the changes, enterprises definitely should follow the trend and make appropriate adaptation. Virtual enterprises are sure to be the organization structure of the future. At present, in order to become virtual enterprises, many enterprises are making adjustment. However, partial reform or adjustment does not correspond to the definition of virtual enterprises. Therefore, only understand the characteristics of virtual enterprises, will we know how an enterprise adapts to the environmental changes. Through the review of literature and case study, this paper includes the characteristics of virtual enterprises as the followings : goal-function oriented¡Bthe emergence of knowledge-based workers¡Btremendous and closely-connected strategic alliance¡Bemploying information technology to proceed process reengineering. Obviously, the pattern of enterprises has been changed¡Fthus, classical analytical models have to make some adjustment. This study which is based on Michael Porter's theory tries to construct a new analytical framework, hoping to help the enterprises to respond to the changing environment that enterprises are facing. The study contends that virtual enterprises should develop efficiency effect and to attract customers to use network effect and special effect to take advantage of learning effect to build entry barrier cooperation revenue to build close relationship with the supply. By synthesizing the practical experience of the case study and outcome of the analysis, this paper has presented some strategies for enterprises to cope with the changing environment. Hopefully these strategies could give other firms some inspirations.

Building virtual community can help a web site to increase its traffic flow, make visitor stayed longer, improve customer loyalty and transact motive. In order to start the dynamic circle of increasing return in a virtual community, the virtual community has to create attractive contents. And system operators (SYSOPs) have playing a critical role in accumulating attractive contents. This research is a exploratory research, we try to find out whether there are some potential traits of SYSOPs that will make the contents more attractive. And we hope the research result can provide as a reference for managers of virtual communities in assessing and training their SYSOPs. We discuss SYSOPs¡¦ traits via three dimensions (lifestyle, characteristic, personal statistics) to test whether these traits will influence the attractiveness of contents. Finally, we find out that most of these SYSOPs are male, 16-25 years old, with college education level, whose average monthly income is less than ten thousands, and most of them has experiences in operation another boards. In the lifestyle dimension, after using factor analysis and cluster analysis, we find out the SYSOPs¡¦ lifestyle can be divided into five types, there are group of X generation, group of independent, group of elegant, group of passive and group of aggressive. But there wasn¡¦t any significant difference between them. In the dimension of characteristic, among three variables (social technique, affiliation, and aggressiveness) there wasn¡¦t any significant difference between the group of high performance SYSOPs and the group of low performance SYSOPs. Finally in the test of personal statistics, we found that experience of operating other boards will provide a significant influence in SYSOPs¡¦ performance. And we use this variable to form a discriminate function, but after test of wilks¡¦ £N, the discriminate ability of this discriminate function wasn¡¦t reach the significant level. So it can not provide an effective forecast for the performance of SYSOPs in virtual communities.

Abstract Since the opening reformation, the economy has been developing fast in Mainland China. The net foundation structure becomes established, net population grows rapidly, so net career and e-commerce are the hot investment in mainland China in these two years. At the same time, the education department is implementing ¡§schools-all¡¨ project. It creates the net education environment in high and primary schools, and also creates the manage value in the mainland China net educational market. This market is special and there are a lot relating issues to it. it is a worthy research topic. This research is based on market of the net education in primary and high schools and social group development. A serial strategy activity is aimed on e- commerce opportunity. The point of this research is the discussion of how do Taiwan businessmen enter this market in mainland China. The individual case of this research is an on-going investment plan. It is the plan of the entering of Taiwan Loxa education network to mainland China market. The strategy of Loxa education network is to focus on educational service and begin with the provision of the net service for schools and develop its own net social groups to provide the members of social groups extra service, enhance the loyalty of the members, enlarge the market opportunity of e- commerce and maximize the business profit and value. The researcher collected and analyzed information of the current develop situation of network in mainland china, the network development in schools and family education consuming markets to clarify the shaping and size of markets. From the interview with related field workers and specialists to understand the market needs and developing tendency. The research is based on the current situation of Loxa education network, business cooperators in mainland China, potential competitors and current market leading companies. To sum up this research, according to the competent strategy of Michael Porter, and new business model of Gray Hamel, I analyzed the manage strategy and tested the manage style of Loxa educational network. From the result of this research, we found the competent strategy of Loxa education is very different from the current competitors in mainland China. From the test of career style and by efficiency, unique, addition service and profit promoter to be the reference of decision and strategy making and to provide the related workers the resource of continuing research in future.

Remote control service on the internet has found many applications such as remote teaching service and industry applications. Our research is not like the traditional method which sends image frames to network users. Instead, we only send the mouse and keyboard message. Our research is composed of two techniques: one is to connect computer¡¦s mouse and keyboard message with virtual device driver, and the other is to provide network function and interface with Win32 application. The accomplishment of virtual device driver is achieved by VxD and Win32 API. We compare our method with other traditional methods in both local network and 56K Modem to test the possibility of remote teaching service. The transmission amount is reduced significantly by our method. Also, the remote teaching service using our method has been successfully performed at 56K modem network environment without the delay phenomenon as shown in the test by the traditional method.

By the increasing use of the internet, people are used to make friends with strangers on the Internet. Would virtual relationship affect the brand image of consumer as real relationship¡HWould virtual relationship influence indirectly the loyalty of the media letting people know each other¡HThe motivation of studying these questions is to realize the indifference of real and virtual relationship. The main purpose of this study wants to analyze three questions¡G 1.Would the on-line marketing activities contribute to close interactions of the members on the web¡H 2.Would the depth, scope and positive attitude of the interactions of the web members affect the e-loyalty of this web¡H 3.Which is the best way to encourage the interactions of the web members¡H This study obtains some important findings. First, the more on-line marketing activities, the more interactions of the members belongs the web. Second, the more interactions of web members, the more friends on this web, and the more positive interactions with members could promote the loyalty of this website. Third, the more interactions of web members would make the person to introduce this website to others. But these commendations of the web members do not reflect the loyalty, the finding maybe be caused by some factors, especially by the tactics of friend-making for finding couple.
