An Empirivcal Study of User Technology Acceptance with Taiwan¡¦s Advanced Passenger Information System ¡GThe Case of National Immigration Agency

Huang, Yuh-Huey 23 July 2012 (has links)
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.

Systems integration and analysis of advanced life support technologies

Nworie, Grace A. 02 June 2009 (has links)
Extended missions to space have long been a goal of the National Aeronautics and Space Administration (NASA). Accomplishment of NASA's goal requires the development of systems and tools for sustaining human life for periods of several months to several years. This is the primary objective of NASA's Advanced Life Support (ALS) program. This work contributes directly to NASA efforts for ALS, particularly food production. The objective of this work is to develop a systematic methodology for analyzing and improving or modifying ALS technologies to increase their acceptability for implementation in long-duration space missions. By focusing primarily on the food production systems, it is an aim of this work to refine the procedure for developing and analyzing the ALS technologies. As a result of these efforts, researchers will have at their disposal, a powerful tool for establishing protocols for each technology as well as for modifying each technology to meet the standards for practical applications. To automate the developed methodology and associated calculations, a computer-aided tool has been developed. The following systematic procedures are interrelated and automatically integrated into the computer-aided tool: • Process configuration, with particular emphasis given to food production (e.g., syrup and flour from sweet potato, starch from sweet potato, breakfast cereal from sweet potato); • Modeling and analysis for mass and energy tracking and budgeting; • Mass and energy integration • Metrics evaluation (e.g., Equivalent System Mass (ESM)). Modeling and analysis is achieved by developing material- and energy-budgeting models. Various forms of mass and energy are tracked through fundamental as well as semiempirical models. Various system alternatives are synthesized and screened using ESM and other metrics. The results of mass, energy and ESM analyses collectively revealed the major consumers of time, equivalent mass, and energy, namely evaporation, condensation, dehydration, drying and extrusion. The targeted processes were subsequently targeted for modifications. In conclusion, this work provides a systematic methodology for transforming non-conventional problems into traditional engineering design problems, a significant contribution to ALS studies.

Global Governance: The New Mode of International Cooperation ?

Hsieh, Pei-Shue 25 August 2003 (has links)
The end of the Cold War represented a constructional transformation in international politics - from bipolar to multipolar . Nevertheless the end of the hostility did not mean the peace and prosperity , on the contrary , there are many latent crises gradually emerging, like security¡Bpolitics¡Becology and cultural. Therefore, how to manipulate the power to resolve the global problem is a very realistic and urgent issue . Due to the new situations of the above, western politicians and scholars have given some new meanings to" governance" with their each values and needs since the 1990's, henceforth, the concept " governance" has successively appeared in the political science¡Bdevelop economics¡Binternational relations and international political economy. Suddenly governance has become the buzzword and popular research topic; and further , the ¡§global governance theory¡¨ has gradually shaped , but also presented the different and blurred definitions . It is similar to abuse the term " globalization" and do not understand its concepts and meanings further. Therefore, the motive of this thesis is to outline and generalize global governance theory and study related subjects further . For this reason , I hope to reach some purposes as follows: First, I will outline the structure and scope of the global governance theory by generalize the history progress of global problem research . Second, I will discuss the relationship between the state and civil society in global governance process , and argue the possible roles of sovereignty states in the future, and the feasibility of " global civil society". Third, I want to find out the conflict and each needs about global governance between advanced states and developing states, and seek the way to improve the inequality for developing states. Finally, I try to use the result of this research to judge the global governance theory whether regard as a new theory.

AES Design Space Exploration with an IP Generator

Chu, Chi-wei 12 July 2005 (has links)
Advanced Encryption Standard is new standard for data encryption and decryption.There is a lot of relevant research so far, but how to find out the suitable design according to the demand has become an important question. So we consult different improvement methods from relevant research, do the design space exploration of AES hardware circuit design with the modeling of parameterized IP Generator.We choose non-feedback mode AES design, which can offer higher security. Using the submodule as different design parameter such as SubBytes/InvSubBytes¡BMixColumns/InvMixColumns¡BKeyExpansion to form many kinds of AES hardware circuit. SubBytes/InvSubBytes¡BMixColumns/InvMixColumns module include two different structure, Integrated and Separate Encryption/Decryption module. KeyExpansion module include two different structure, on the fly and Store in Rom.There are three different keylength 128¡B192¡B256, which can form forteen different structure. We provide circuit gate count¡Bthroughput¡Bpower consumption information of different AES hardware citcuit design by the synthesis and gate-level simulation result. According to our implementation, the user can choose the suitable AES hardware circuit design method and which can solve the problem above. We also provide an automatic test pattern generator for our design verification, it makes our design can be integrated efficiently. Our experiment result show that, the design which Encryption/Decryption module use integrated structure have less circuit gate count than which Encryption/Decryption module use separate structure while throughput constraint is between 700MHz to 1300MHz (It¡¦s depend on different keylength combination). But while the throughput constraint become higher, the circuit gate count of integrated structure rise faster than separate structure. And the situation is the same with power consumption.The maximum throughput of KeyExpansion module use store in Rom structure is higher than whcich use on the fly structure.

HAn, Chia-Yun 19 July 2007 (has links)
The purpose of this research is to compare the performance for the water quality of two traditional water treatment plants (WTP) and three advanced water treatment plants (AWTP), and to investigate the treated drinking water in distribution systems in Kaohsiung area for promoting the consumers¡¦ self-confidence. Samples of the treated water from five major water supplies¡¦ WTP(noted numbers: WF1, WF2, WF3, WF4 and WF5) and the tap water at user¡¦s end were selected in planning of this work. It was the traditional WTP stage with treated drinking water and distribution systems in Kaohsiung area During 91 year to 92 year, so we conducted WF1 and WF2 of 8 times sampling and WF3, WF4 and WF5 for 2 times sampling at this stage. In and after 93 year, we conducted WF1, WF2, WF3, WF4 and WF5 of 8 times sampling from 93 year to 94year for the advanced WTP stage. The major tests related with the parameters of influencing operation condition included pH, odor (abbreviated as TON), total trihalomethane (abbreviated as THMs), haloacetic acids (abbreviated as HAAs), nitrogen (abbreviated as, NH3-N, hardness, total dissolved solid (abbreviated as TDS), alkalinity, total organic carbon (abbreviated as TOC), calcium ion, flavor profile analysis (abbreviated as FPA), and suspension observation in boiling with treated waters from two WTP , three AWTP and the tap water at user¡¦s end in a distribution system. It point out the better quality of treated water used the advanced water treatment plants than that of traditional water treatment plant. The items with improvement of water quality, including THMs, HAAs, hardness, TON, 2-MIB, TOC, alkinality and Ca ions concentration, is presented. Their efficiency for improvement are respectively 47%, 29%, 43%, 11%, 29%, 15%, 14% and 34%. The insignificant efficiency were concentrated at TDS, NH3-N, pH and FPA. Water quality of six items are fitted for the drinking water standard at present in Taiwan (such as: odor<3 TON; THMs<0.1 mg/L; NH3-N<0.1 mg/L; TDS< 600 mg/L; Hardness <400 mg as CaCO3/L; 6.0<pH <8.5). The HAAs is fit for water quality USEPA first stage water standard (HAAs<80 £gg/L). In the suspension observation in boiling experimentation, we cooperate with the experiment of suspension observation in boiling to do contrast with TDS and hardness experiment, which can find out, the treated water after the advanced procedure, the time with boiling increases, the condition of its suspended substance has great reduction. It show treated drinking water after the advanced WTP can huge improve the traditional WTP¡¦s white suspended substance or white material precipitate questions in the boiling. In the contour map for water quality , we found that Gushan District, Lingya District, Qianzhen District, Xiaogang District, Fongshan City and Daliao Shiang etc had higher concentration profile in the four season (included spring, summer, fall and winter ) and during two seasons (included raining and drying) in the water supplies systems. We hope the contour map can offer a clear information of conveyer system administrator of drinking water and let administrator know where areas have high concentration produced in water quality management planning, in order to having priority or effective solutions (included washing the pipeline, changing the pipeline, changing the water flow, etc.).

Ling, Chien-Ling 01 September 2002 (has links)
The occurrence in which Nursing Accreditation has included Clinical Ladders Program impacts the Nursing Department significantly. Nursing administrators of hospitals need to plan and adopt Clinical Ladders Program in order to maintain good performance and development. The published literatures in planning this program are numerous. We investigated the influence of Clinical Ladders on nursing staff. The purpose of this study was to differentiate nursing competency, and satisfaction of program between low level of staff nurses and high level of staff nurses. Another purpose was to explore the influencing factors in nurse¡¦s choice of advanced role in Clinical Ladders Program. The study is conducted by questionnaire surveying. The designing of questionnaire was based on the reviewing of literature and the studying of reference. The researcher sent out 700 questionnaires and 571 were responded. The responding rate was 79.51%. SPSS for Window was in use of data analysis, the statistic methods of Mean, Standard Deviation, Factor analysis, ANOVA and Scheffe¡¦s test, Pearson¡¦s Correlation, Multiple Regression analysis and Logistic analysis. Results of this study were as followed: 1. Comparing different levels, the fourth level nurses had the highest scores in eight-dimensional and total nursing competencies; the first level nurses had got the lowest scores. 2. The nurses on higher level had higher satisfaction in program. 3. Most of staff nurses tend to choose CNS as advanced role in their nursing career. 4. The influencing factors of staff nurses in choosing the advanced role included individual characteristic, hospital trails, nursing competencies, and program satisfactions. Recommendations were made regarding nursing policy, nursing administration, nursing education, and nursing research.

Evaluation of daytime vs. nighttime red-light-running using an advanced warning for end of green phase system

Obeng-Boampong, Kwaku Oduro 01 November 2005 (has links)
The problem of dilemma zone protection and red-light-running is especially important in certain rural intersections due to the higher speeds at these intersections and their isolated nature. In addition, the presence of a larger percentage of trucks mean that adequate warning and help need to be given to these truck drivers in order to enable them to stop safely, or proceed through the intersection before the onset of red. To curb any potential danger at such intersections, a Texas Department of Transportation (TxDOT) research project on Advanced Warning for End of Green Phase (AWEGS) at high speed intersections deployed AWEGS at two rural intersection sites ?? Tx 6 @ FM 185 near Waco and US 290 @ FM 577 in Brenham. The deployment of AWEGS involved a Level 1 and a later upgrade to a more efficient Level 2 in Waco. Initial results on red-light-running, even though promising, were expressed as observed red-light-running events per day. These resulting rates did not reflect exposure, and the results also raised some concerns with regards to some increase in red-light-running from Level 1 to Level 2. A more detailed analysis of the red-light-running issue at these two sites is provided in this thesis. The main areas of red-light-running analyses presented here are with respect to the reductions in red-light-running rates for the exposure factors of number of cycles and vehicular volumes, the comparison of day and night RLR rates and the nature of speeds of vehicles running the red light at the intersection in Waco. AWEGS was found to reduce the total red-light-running per exposure factor after its deployment. Both Level 1 and Level 2 AWEGS operations were found to reduce red-light-running by up to 60%. Generally, total red-light-running per exposure factor between Level 1 and Level 2 was found to be about the same. Level 2 had lower daytime red-light-running rates and higher nighttime rates than Level 1. Generally, day rates were found to be higher than night rates for all levels of AWEGS deployment. It is recommended that, to better understand the operational aspects of AWEGS and to improve its operations, more implementation of AWEGS and further tests be done. An automated method to collect and analyze data needs to be developed as well as a means of automatically recording video data for calibration and verification It is also recommended that Level 1 technology be implemented in areas where the Level 2 technology may be either too complex or too expensive.

Design and Implementation of a Security Mechanism for network communication

Wang, Shan-rung 28 August 2009 (has links)
Most process of lease is done manually in the past. Since the networks were used extensively and systems of Point of Sales risen quickly, the efficiency of administration of payment flow had been obviously promoted. What are mostly encrypted are information of payment flow, but what we encrypt is the information of leased products this time. We apply encryption technique to the lease system, and access information via RS-232 devices, such as SmartCard Reader and EM Reader. After processing of system and encryption, the system will transfer the processed data to the server. In this paper, we take Kaohsiung C-Bike Lease System for case study, our discussion will focus on network packet, data encryption, and real-time monitoring. We will also introduce critical features and mechanisms of the lease system and address some issues we encountered. This system encrypts data via Advanced Encryption Standard, sends out data packets via TCP/IP, and monitors leased bikes via databases and framework of multi-thread.

Developing Humidified Gas Turbine Cycles

Bartlett, Michael January 2002 (has links)
<p>As a result of their unique heat recovery properties,Humidified Gas Turbine (HGT) cycles have the potential todeliver resource-effective energy to society. The EvaporativeGas Turbine (EvGT) Consortium in Sweden has been studying thesetypes of cycles for nearly a decade, but now stands at acrossroads, with commercial demonstration remaining. Thisthesis binds together several key elements for the developmentof humidified gas turbines: water recovery and air and waterquality in the cycle, cycle selection for near-term, mid-sizedpower generation, and identifying a feasible niche market fordemonstration and market penetration. Moreover, possiblesocio-technical hinders for humidified gas turbine developmentare examined.</p><p>Through modelling saltcontaminant flows in the cycle andverifying the results in the pilot plant, it was found thathumidification tower operation need not endanger the hot gaspath. Moreover, sufficient condensate can be condensed to meetfeed water demands. Air filters were found to be essential tolower the base level of contaminant in the cycle. This protectsboth the air and water stream components. By capturing airparticles of a similar size to the air filters, the humidifieractually lowers air stream salt levels. Measures to minimisedroplet entrainment were successful (50 mg droplets/kg air) andmodels predict a 1% blow down from the water circuit issufficient. The condensate is very clean, with less than 1 mg/lalkali salts and easily deionised.</p><p>Based on a core engine parameter analysis for three HGTcycle configurations and a subsequent economic study, asteam-cooled steam injected cycle complemented with part-flowhumidification is recommended for the mid-size power market.This cycle was found to be particularly efficient at highpressures and turbine inlet temperatures, conditions eased bysteam cooling and even intercooling. The recommended HGT cyclegives specific investment costs 30- 35% lower than the combinedcycles and cost of electricity levels were 10-18% lower.Full-flow intercooled EvGT cycles give high performances, butseem to be penalised by the recuperator costs, while stillbeing cheaper than the CC. District heating is suggested as asuitable niche market to commercially demonstrate the HGTcycle. Here, the advantages of HGT are especially pronounceddue their very high total efficiencies. Feasibility prices forelectricity were up to 35% lower than competing combinedcycles. HGT cycles were also found to effectively include wasteheat sources.</p><p><b>Keywords:</b>gas turbines, evaporative gas turbines,humidification, power generation, combined heat and powergeneration.</p>
