Due to there is no record of migration in China, we estimate migration by Johnson¡¦s (2003) way. Estimates of migration among the provinces of China area were made by comparison of the provincial population from the 1994 to the 2003 censuses. The estimates were made by comparing every year between 1995 and 2004 population of each province with what it would have been if population had increased solely due to national growth-the excess of births over deaths. Unfortunately, the estimate of the increase in provincial populations due to migration was much greater than the estimate of the loss of population by migration. Possible reasons for the difference in the estimates due primarily to the underestimation of immigrants. Because this difference amounts to less than 3% of the 1995-2004 population of China, the data is still useful to us. Because wage is a kind of price, we adopt the method by Engel and Rogers (1996), and use the law of one price to examine the wage differential in China area. We find that high migration gap, long distance and the presence of coast all lead to an increase in wage differential in China area. We also find that distance and border reduce differential among provinces. Note that the distance has a positive effect on wage differential, and the square of distance has a negative effect. This means the distance relationship were concave. Finally, we examine the tendency in the standard deviation of wage differential and migration gap among the provinces of China during the period 1994-2003. The standard deviation of wage differential widened, and the standard of migration gap did not display strong increasing or decreasing. Although the growth rate of wage differential was positive, it reduced in recent years. The average growth rate of migration gap was close to zero, there is not significant tendency.

Abstract The fundamental purpose of this research is to discuss the solution strategies and error types when seventh-grade students in middle school solved simple equations with one unknown and application problems; we hope results can provide reference for teachers in remedial teaching and in improving instructional. The items in the examination paper used in this research were taken from 12 past papers of basic competency test in Taiwan (2001 to 2006, twice a year). The subjects were students from Kaohsiung City Y Middle School (City region), Kaohsiung County T Middle School (Ordinary town) and Pingtung County Z Middle School (Near seacoast) forming a convenience sample. The investigators selected 2 classes from each school by random, with a total of 188 students. The main results of this research are as follows: 1. There are ten questions and the average proportion of correct answers is 49.10%; it shows that, at least 51% students have difficulties in solving symbolic operation and linear equations with one unknown. 2. The solution strategy student used most frequently is Removal of Term. Equal Axiom and Enumeration Evaluation Method were used occasionally. No student used Substitution method, Reduction method and Hidden method. 3. The main error types are: missing knowledge of using symbol; do not understand meanings of symbols; combine dissimilar terms freely; do not understand the meaning of bracket; cannot do calculation involving bracket; and, cannot simplify equation etc. 4. The main reasons for failures are: do not understand the meaning of equation; do not understand combination rules of like terms, position of symbol, unknown variables; whether containing fractions in reducing equation will also cause an error. Keywords: linear equations with one unknown, solution strategies, error types.

Abstract of Thesis The title of this thesis is Macaw case study- the exploration into relation of central and local government under ¡§one country, two system.¡¨ Deng Shao Ping, the last one of the Communist China¡¦s leaders group and general designer for Communist China¡¦s ¡§reform, door opening and modernization policy¡¨ first introduced the concept of ¡§one country, two system¡¨ and applied this theory on the its unification effort of Taiwan. In July, 1997, under Communist China¡¦s guideline-¡§one country, two system¡¨ British Hong Kong administration, was peacefully transformed to become Hong Kong autonomy of Communism China. On December 20, 1999 , Portuguese Macaw administration was also transformed to Macaw autonomy of Communism China. In order to find out the development history of ¡§one country, two system¡¨, this thesis will first review the publications that discuss central and local government relationship, then explore the development of local political system utilizing operation principle of Mainland China¡¦s politics. Based on communism¡¦ tradition theory- Marx-Leninism; Mao and Deng principal, this thesis will analyze how Deng develop, solidify and finalize his claim, ¡§ Establishment of a socialism country with Chinese character¡¨ starting from the concept of ¡§ one country, two system¡¨. Finally, Macaw case study will be carried out to explore all the possible issued faced for before and after take over of Macaw under the theory frame work of ¡§one country, two system¡¨ and from the central/local relationship of Mainland China. Hopefully, the conclusion of the study can help to understand (1) the feasibility of political system and development under Communist China¡¦s ¡§one country, two system¡¨ and (2) possible future development and trend, direction and outlook.

Abstract of Thesis The title of this thesis is A comparative study of the one ¡V china policy during the eras of Chiang Khai-Shek and Chiang Ching-Kuo. According to the relationship of the China Government and Taiwan, the cooperation on economic issue but the conflict in political ones, and the most controversial issue now is ¡§ One-China ¡¨ policy. Both sides of Taiwan Strait, the Authorities have the different explanations of it because the different of the histories and backgrounds between Taiwan and China since Ming and Ching dynasties. On this thesis, it discuss the policies of Chiang Khai-Shek and Chiang Ching-Kuo ¡¥s eras to handle this problem especially the international relationship of Taiwan and China during that times. After World War ¢º, America becomes a big country to be a turn point of the relationship between Taiwan and China, that ¡¥s what this thesis is written and discussion. According to the different background and histories, it do a comparative study of the policies between Chiang Khai-Shek and Chiang Ching-Kuo in final chapter.

In view of globalization, technology and the influence of the technological progress in transportation, after the opening of the high-speed railway in 2007, the distance from north to south becomes much shorter, thereby pushing through the formation of the one-day living circle. What¡¦s more, due to the development of the metropolitan areas, the gap between urban and rural areas is shortened. Therefore, the primary mission for Taiwan¡¦s administration in the future should be not only to rethink the distribution of the current 23 counties and 358 township cities, but to figure out the appropriate adjustments. With more than 50 years of H.R.(Home Rule) in Taiwan, the relationship between the central government and local ones has been inconsistent. Local governments actively seek to build the major public constructions, such as setting up the Science Park, ports, airports, one characteristic for one town¡Kand so on. However, these phenomena lead to the reduplication of administrative resources, the unequal distribution of social resources, the excessive personnel costs caused by the operation of the system, and the heavy financial burden to local governments. Hence, we must rethink how the regions should be redrawn in coordination with such ways as national land planning, city planning or establishment of divisional laws for administrative regions. This policy-making process not only involves political, administrative, social, legal, and economic dimensions, but also attracts many politicians¡¦ attention. Only through the theories and practice will the sustainable development of Taiwan's system be established. As a result of the necessities and urgency for the redistribution of the administrative regions, this paper, in conclusion, takes the viewpoint of land-planning framework and network , as well as proposes to use the idea of regional government to help all counties solve cross-border governance issues. Furthermore, owing to highly political attention, the issue for the adjustment of administrative division may be settled by civic awareness, promotion of civic accomplishments, or even a referendum in the end.

An advanced architecture of learning system with flexible, mobile and joyful features for supporting ubiquitous learning is developed in this research. The architecture consists of five hardware key elements and a supporting information system to form a brand-new ubiquitous learning system. We call the designed and developed system as Ubiquitous Open-structured Neo-tech Edutainment (or u-ONE System for short) which includes learning robot, sensing input device, mobile computing device, mobile output device, wireless local network and u-ONE Software. The design and development of u-ONE System is guided by experiential learning theory, constructivism learning theory, and joyful learning element. Instruction, collaboration learning and self-learning of application modes are supported by u-ONE Software for realizing ubiquitous learning. The aim of this research is to design and develop a prototype of u-ONE System includes hardware and software components for supporting children¡¦s learning by using robot and RFID. Instructor and learners can meet at any place with their own gears to form a u-ONE System and start instruction and/or learning activities. Only instructors need to operate the control station for coordination; learners just intuitively interact with learning robot by a natural and person-to-person-liked interaction method. In u-ONE System, learners do not need to have good information technologies literacy such as the keyboarding skills which are especially crucial for the earlier childhood learners. Besides, many parents and educators are concerned of watching computer screen for a long time that may harm children¡¦s eyesight; u-ONE System provides an alternative solution for this. This research¡¦s experiment result found most learners could arouse their learning motivations and help them concentrate on learning activities. The class order is also improved for instructors more easily to control the behaviors of learners during the class.

Section Steel usually is a order-oriented production and not easy to resell. The material cost is large percentages of overall production cost. Hence, the key to boost efficient management is to increase the material output rate. In other words, we need to publish a efficient and reasonable cutting plan before production. And the cutting plan can cope with change to meet the market demand. The cutting plan designing is a one-dimensional cutting stock problem, and also is a typical bin packing problem. In this study we examine a combined heuristic approach for this problem. The proposed approach combines two themes of solving method¡Ga neighborhood search algorithm with threshold accepting techniques, and a Branch and Bound method. The performance of the combined heuristic approach was verified by running several benchmarking problems and the results were reported. Experimental results indicate that the proposed solving process can effectively search the feasible region and avoid being trapped in local optimal.

Numerical modeling techniques commonly used to compute the response of soil and rock media under earthquake shaking are evaluated by analyzing the observations provided by instrumented borehole arrays. The NIED Kik-Net database in Japan is selected as the main source of borehole array data for this study. The stiffness of the site and the availability of high intensity motions are the primary factors considered towards the selection of appropriate Kik-Net borehole arrays for investigation. Overall, 13 instrumented vertical arrays are investigated using over 750 recorded ground motions characterized by low (less than 0.05 g) to high (greater than 0.3 g) recorded peak ground accelerations at the downhole sensor. Based on data from the selected borehole arrays, site response predictions using 1-D linear elastic (LE) analysis, equivalent linear (EQL) analysis, equivalent linear analysis with frequency-dependent soil properties (EQL-FD), and fully nonlinear analysis (NL) are compared with the borehole observations. Initially, the low intensity motions are used to evaluate common assumptions regarding 1-D site response analysis. First, we identify the borehole wavefield best simulating the actual boundary condition at depth by comparing the theoretical linear-elastic (LE) and observed responses. Then, we identify the best-fit small-strain damping profiles that can incorporate the additional in-situ attenuation mechanisms. Finally, we assess the validity of the one-dimensional modeling assumption. Our analyses indicate that the appropriate boundary condition for analysis of a borehole array depends on the depth of the borehole sensor and that, for most of the considered vertical arrays, the one-dimensional assumption reasonably simulates the actual wave propagation pattern. In the second part of this study, we evaluate the accuracy of the EQL, EQL-FD and NL site response methods by quantifying the misfit (i.e., residual) between the simulations and observations at different levels of shaking. The evaluation of the performance of the theoretical models is made both on a site-by-site basis and in an aggregated manner. Thereafter, the variability in the predicted response from the three site response methods is assessed. Comparisons with the observed responses indicate that the misfit of simulations can be significant at short periods and large strains. Moreover, all models seem to be characterized by the same level of variability irrespectively of the level of shaking. Finally, several procedures that can be used to improve the accuracy of the one-dimensional EQL, EQL-FD and NL site response analyses, are investigated. First, an attempt to take into account the shear strength of the soil materials at large shear strains is made. Additionally, several modifications to the EQL-FD approach are proposed. The proposed modifications are evaluated against recordings from the borehole arrays. Our analyses indicate that the accuracy of the theoretical models can be, partly, increased by incorporating the proposed modifications. / text
