To increase the efficiency of speedy customs clearance for the outboard and inboard passengers, the Nation Immigration Agency under the Ministry of Interior has adjusted the related administrative procedures, such kind of management policies. Take the Advanced Passenger Information System (APIS) constructed in the major ports of Taiwan as an example. It requires the ship lines submit the related information of the ships and the basic information of the crewmembers to the information-processing center of the target state for advanced inspection before entry or exit. The center can judge whether there are control subjects among them by the submitted information, and further take some prevention measures in advance. This system is one of the key policies of national security in Taiwan. It is found from the literature review that although the APIS built by the National Immigration Agency has put into practice, the system performance evaluation is so rare, furthermore, the use willingness and achievement of the related practitioners and carriers can¡¦t be known. Therefore, this study takes the Technology Acceptance Model (TAM) as the main axis to develop a TAM for the APIS. Moreover, it takes the Kaohsiung Port Brigade of Nation Immigration Agency as study scope, and the freight forwarders as the study objects, to conduct investigative study and evaluation on the situation of importing the APIS technology and the factors affecting the use of that system. The purpose of this study is to realize the effectiveness of the system implementation and subsequent improvement directions, as well as provide suggestions on how to carry out the system in the future. The study shows that the APIS effectiveness can help to increase the users¡¦ positive attitude, but the attitude towards the system can¡¦t effectively improve the users¡¦ positive intention, the information security awareness needs to be strengthened, the behavior control can¡¦t effectively increase the users¡¦ positive intention, and the persons who are in charge of the related fields show low willingness of using the APIS. Besides, the practitioners that have been founded for a longer time and developed into a large scale show a higher recognition degree to that system, and the education level also affects the willingness of using the APIS. The follow-up studies suggest reviewing the APIS promotion plan and making some improvements for it. Moreover, the involved institutions should provide assistance in the improvement of the human resource structure, make some related incentive, and enhance the information security concept, as well as conduct policy study, so as to facilitate the improvement and smooth implementation of the system.

The rapid development of information technology (IT) has impacted the competitive environment between properties. Today, more and more companies introduce information system to flow internal messages freely, reduce the communication cost and provide support the important messages to managers for fast decision. By this way, the enterprise could maintain its competitive advantage. To introduce the information system¡]IS¡^ is really costly, companies should probe the effects before and after the investment of IS . We have learned from literatures that measurement of service quality is the proper means to gauge the information system. This study is to assess information system at the base of ¡uIS-adapted SERVQUAL instrument¡v and ¡uThree-column format¡v. A survey, which adapted to individual company, was conducted with some measures modified from the viewpoint of captioned company. 436 valid samples were taken from more than 8600 employees by stratified random sampling. The major findings are (1) instead of four dimensions expected from the original model, only two service components, attitude perspective and skill perspective, are identified in the service quality of information system for manufacturing industry,¡]2¡^the difference between ¡¥perceive quality¡¦ and ¡¥self-confident quality¡¦ is significant, ¡]3¡^Following the demographic variables among ages, positions, working departments and academic degrees, it appears no significant difference in the attitude perspective and skill perspective of service quality concerning information system.

The thesis develops a driving assistant system that can locate the positions of the lane boundaries and detects the existence of the front-vehicle. It can also provide warning mechanism so as to avoid the danger as possible collides with previous vehicle. In lane recognition, we utilized the largest gradient of luminance value to detect possible road surface marking, then cooperated with the marking static and dynamic behavior of road surface characteristic to set up road surface marking and detect system. On the other hand, we considered vehicle detection leach the vehicle bottom shade characteristic from dynamic area threshold processing, and then judge and label where the vehicle exits. By the principle of the optics image formation, we estimated the relative distance from the previous vehicle. In this thesis, we proposed an easy and fast measure for previous vehicle of 96% correct rate in different environment. Running on typical 1.7Ghz processor system results up to 80 frames per second.

Our country is under promoting the electronic government's policy, the ones that proposed old government procurement procedure reengineer, is it draw lessons from business process reengineer in successful enterprises as, use the information and technological construction of communication to the electronic procurement system and become and promote one of the schemes mainly, in the hope of building and constructing an efficient government procurement procedure environment. Count in accordance with the Directorate-General of Budget, Accounting and Statistics and Executive Yuan, the annual total of government organizations exceeds the huge budget of 4 trillion NT, carry out by way of government procurement. Good Yu of the procedure system of government procurement, influences country's whole development to the hard iron. Supervising and reporting and counting according to the Public Construction Commission Executive Yuan, the public works is a domestic large-scalest industry, purchase the system and effect of carrying out, have extremely close relations to procure the procedure with the public works. Public Works Bureau of Kaohsiung city government can get and mark several 339 (21.16%) which account for the whole municipal government of Kaohsiung in 2003 most; The public works of amount of money of master budget are the highest. And the public works procurement, with relevant in describing, most apt to form procedure complicated, is it mark to tie, situation marked to enclose take place. So, this text is the view assessed with the performance probes into the assessment of the public works procurement procedure efficiency of Public Works Bureau of government of Kaohsiung. First of all, the measurement index of building the performance of constructing and assessing, regard ¡§ time, cost, manpower¡¨, three indexes, as and assess the focal point, use secondary analysis, understand that Public Works Bureau will purchase the execution efficiency of electronization in 2003, and then use the interview way of the depth, make to the procedure of public works purchase practical operation and purchase personnel and carry out the firsthand materials which purchase the business, build and construct the procedure that the public works is purchased by combining the software of structure of information system (architecture of integrated information system, ARIS) afterwards, assess the question of the public works purchase procedure of job bureau of government of Kaohsiung, propose the improvement of the public works purchase procedure procedure, increase the efficiency that the public works is purchased. Comprehensive secondary analysis, ARIS procedure analysis and interview result of the depth: The execution situation purchased in electronization of Public Works Bureau of government of Kaohsiung, has already reached the stage that electrons have opened bid at present; Effect of electronization its, neck mark person who reach 62.78%, electron submit a tender the reaching rate is 0%, have not reached the set goal; Put forward the following suggestions after putting in order and purchasing personnel's interview suggestion synthetically, whether support reference that follow-up improve, in order to reach and purchase the efficiency carried out in electronization. Will study and propose dividing into(1)the decree respect; (2)management respect; (3)systematic respect; (4)education and training respect. Combine the analysis result, carry out the present situation about the public works purchase procedure, purchase procedure finish electronic procedure in an all-round way yet, execution of dual track system at present is it appear for fear of procedure efficiency to have at present, so, facilitate electronization to purchase the execution of the procedure and help the government and manufacturer to purchase benefit that the trade carry out.

With the rapid advances in technologies, strategies for efficiently operating the spatial data are needed. The spatial data consists of points, lines, rectangles, regions, surface, and volumes. In this thesis, we focus on the region data. There are many important and efficient operations for the region data, such as neighbor finding, rotation, and mirroring. The nearest neighbor (NN) finding is frequently used in geographic information system (GIS). We can find the specific point (e.g., a park, a department store, etc.) that is the closest to our position in geographical information systems. In any representation for the region data, it is not instinctive and easy for nearest neighbor finding, since the coordinate information has been lost. Voros, Chen, and Chang have proposed the strategies for the nearest neighbor finding based on the quadtree in eight directions. Chen and Chang have proposed the nearest neighbor finding based on the Peano curves. These strategies for the nearest neighbor finding based on the quadtree and the Peano curve use a looping process, which is time-consuming. On the other hand, in recent years, many researchers have also focused on finding efficient strategies for the rotating and mirroring operations, which is useful when the animation is performed by computers. The boolean function-based encoding is a considerable amount of space-saving with respect to the other binary image representation. The CBLQ representation saves memory space as compared to the other binary image representations that have proposed the strategies of the set operations. However, the processes for obtaining the rotated or mirrored code based on these two representations are time-consuming, since the coordinate information of all pixels has been lost. Therefore, in this thesis, first, for the nearest neighbor finding based on the quadtrees and the Peano curve, we propose the strategy which uses the bitwise and arithmetic operations, and it is more efficient than the strategies based on the looping processes. Next, we propose efficient strategies for rotating and mirroring images based on the boolean function-based encoding and constant bit-length linear quadtrees (CBLQ) representations. From our simulation study, first, we show that our strategies based on the quadtree and the Peano curve require the least CPU-time and our strategy based on the Hilbert curve requires the least total time (the CPU-time + the I/O time) among the strategies for the nearest neighbor finding based on the quadtree and the three space-filling curves. Next, in most of cases, when the black density is no larger than 50%, the CPU-time based on the boolean function-based encoding is less than that based on CBLQ.

Knowledge transfer is an interaction between knowledge receiver and provider. They acquire new knowledge through all kinds of media during this process. Furthermore, they assimilate, develop, innovate, and apply it. When there is some knowledge lacked inside an organization, there will be a knowledge gap. In order to bridge the knowledge gap, they need to obtain external knowledge through knowledge transfer. Knowledge transfer is the most important and difficult one in all of the knowledge management issues. The study is to analyze the important factors, which influence knowledge transfer by probing into the process of information system development. This study develops based on the research of Harald et al. (2002). Three contexts of constructs influencing knowledge transfer were induced: (1) domain knowledge dimension, including tacitness, complexity, and specificity, (2) system development team dimension, including system development experience and the degree of domain knowledge understanding, (3) partnership quality, including trust, mutual understanding, benefit and risk sharing, and commit. This study focuses on these three constructs to find the impacts on knowledge transfer performance. This study tested the impact of knowledge transfer on ISD performance, and analyzed the critical factors influencing inter-team knowledge transfer through empirical survey. And the samples are the members of domestic system development teams. The research result reveals that knowledge transfer performance has significant impact on system development performance. On the other hand, partnership quality has the most impact on knowledge transfer performance and system development experience is the next. Furthermore, ISD performance is affected by partnership quality, too. This result will provide a different point of view of ISD, which can guide teams to produce more successful systems from the knowledge management perspective.

The study aims to find key factors of information system success in a non-profit education and training institute. The institute under study has five centers providing on-job training and long-term cultivation in the area of information technology. Facing the pressure of continuing growth and increasing competition, the institute has begun the e-projects since many years ago. After several years of system development and implementation, a survey of users¡¦ satisfaction showed that only part of the systems was acceptable. This study adopts the Technology Acceptance Model (TAM) as the primary research framework along with the service quality model and comes up with five success factors including perceived usefulness, perceived ease-of-use, system quality, information quality and service quality. Moreover, user satisfaction is taken as dependent variable of the framework. In order to differentiate the successful system from the unsuccessful system, a curriculum management system and a knowledge management system was selected to represent the successful and unsuccessful systems respectively. The case study method and questionnaire survey wre both used as research method. In the case study, the development and implementation background, process and results were investigated. The survey method was used to verify the differences between the two systems using the five factors mentioned previously. The results of questionnaire survey and statistical test clearly distinguish the two systems and support case study findings. The results of this study can serve as guideline to improve the users¡¦ satisfaction as well as to improve the information system success.

Introducing an information system is an organizational learning process, during the process of development an information system , organizational members learn how to introduce information technology into an enterprise. While learning, however, most of individuals always act defensively without any awareness, when solving their problems. For the purpose of Organizational learning, these defensive behaviors will bring counterproductive or unintended consequences or limited learning, and result in the information system which cannot completely meet the business needs or cause project¡¦s schedule delay. In this research, we use the process research model methodology which developed by D. Robey and M. Newman in 1992 year and 1996 year, identify the 16 sequences event process in the case of healthcare information project of E hospital, and define them as either encounters or episodes. From the view of organizational defense, we analyze these events base on the theories of defense mechanism from Argyris and documents about organizational defense from information management. The analyzing results show that there indeed exist many defensive behaviors during the development of project of E hospital, and thus cause negative effect. This research offers these defensive phenomenon for the CIO and project managers to take precaution against same mistake while implementing information project, and help organizational members learning effectively while introducing an information system, in order to reduce risk of project failure and improve control of information project¡¦s cost, quality and schedule.

While the low profit times is coming, most of the enterprises hope to strengthen the interior information construction to promote the ability of obtaining profit or enhancing the management skill. With the progress of information technology, descent of hardware price, more friendly user interface, fast computer processing speed and the simplification of information technology, all these factors will aid business management for the enterprises. Recently electronic-business has turned into the mainstream, to implement the information system and build the e-business enterprise nowadays are becoming the hot topic in business management. When the macroeconomic environment is changing quickly, now the state-owned enterprise is facing the unprecedented pressure of reformation. The reformation includes the simplification of manpower, the objective effect management and running the state-owned enterprise by the private stockholder. In order to face the changes and promote the efficiency, all enterprises step into implementing all kind of information systems to enhance the management efficiency. With the electronic trend, a state-owned enterprise has also implemented many information systems, however, the process turned out to have some success and some failure. What are the critical success factors and how do they work? It is worth to do research in depth. This thesis will take ¡§technology acceptance model¡¨ for basis and add something like ¡§computer self-efficacy¡¨ and ¡§task-technology fit theory¡¨ for external variance to discuss what the critical success factors are to implement the information systems for the state-owned enterprise. Besides, we hope the conclusion of the critical success factors will be the reference for other state-owned enterprises or government departments.

This study investigates the effect of locus of control on the relationships among product innovation, management accounting system (MAS), and organizational performance. 300 participants were randomly drowned from the electronic industries¡¦ managers in Taiwan Security Exchange and 132 useful responses were used to validate the hypotheses by path analysis. The results shows that: 1. Product innovation and organizational performance have a significant positive relationship 2. Product innovation and perceived usefulness of MAS information have a significant positive relationship 3. Perceived usefulness of MAS information and organizational performance are positively correlated 4. Product innovation has an indirect effect on organizational performance through perceived usefulness of MAS information 5. When managers tend to be internal locus of control, the linkage between product innovation and perceived usefulness of MAS information will be stronger 6.When managers tend to be internal locus of control, the linkage between perceived usefulness of MAS information and organizational performance will be stronger. However, when manager tend to be external locus of control, the hypothesis between perceived usefulness of MAS information and organizational performance is not supported. Management implications of this study are suggested. Businesses facing the global competition have to adopt the strategies of product innovation to create profits, promote market shares and improve strength of competition and then achieve organizational performance. Business using higher degree of MAS information will improve their adopting strategy of product innovation and enhance their organizational performance. Managers with internal locus of control will aggressively use MAS information and improve the linkage between product innovation and organizational performance effectively.
