In order to attain the best-educated people in a rapidly changing, modern society with English is an official language, this study applies the problem-based learning (PBL) method to the English Science Class. PBL problems were developed for PBL classes, and their effectiveness has been proven. The focus of this study was five PBL questions posed during the first semester, targeting seven learners in the fourth grade of Elementary School A. The questions were divided into levels aimed at each grade, with the emphasis on specialized English education. Learners wrote journals, peer evaluations, and self-evaluations after finishing their PBL classes. Also, a survey about PBL was conducted after the first semester. The results of the study showed that learners experienced an 86% improvement in presentation skills, an 86% improved interest in learning, 86% better understanding, and 100% improvement in both problem-solving skills and cooperation. On the other hand, learners had difficulty in understanding PBL problems, and with research using the internet. PBL was somewhat unfamiliar to the students, but the survey found that learners are already aware of its effectiveness, and that they are interested in PBL.

Although data analysis in earlier days had been sufficiently done only by character user interface, users of these days are more used to the graphic user interface and the requirements for the user interface are gradually varying and increasing. In order to meet users' various wants and needs and to develop well-equipped interface, not only software developers but also professional designers who can complement the technique of the developers are needed. But in reality there are many restrictions and difficulties for developers and designers to work together cooperatively. Moreover, developing user interface in use of 3D type of graphics and animation techniques causes the rise of the developing cost. The thesis attempts to design and implement 3D visualization for real-time sensor data collected by the various environmental sensor and measuring devices, by using WPF (Window Presentation Foundation) which can make both developers and designers work together cooperatively and which makes it possible to implement various multimedia functions such as a 2D and 3D type of graphics, animation techniques, and an acoustic effect.

The impact of income and education level on the clinical and pathologic characteristics, implementation of clinical breast examination (CBE), and treatment patterns of a small population of Chinese female breast cancer patients was studeied in order to provide a theoretical basis and statistical reference for further nationwide research. We included 484 pathologically confirmed female primary breast cancer inpatients of the First Affiliated Hospital of Medical College of Xi'an Jiaotong University from February 2003 to January 2004. All cases were reviewed and relevant information was collected using a designed case report form (CRF). Chisquare tests, rank-sum tests, and Fisher's exact tests were used in the analysis. Our analysis showed that: (1) women in different occupation groups had significant differences in tumor size, pre-operative mammography, surgical options, post-operative estrogen receptor (ER), progestin receptor (PR) and human epidermal growth factor receptor 2 (Her2) status, and post-operative radiotherapy and chemotherapy (P < 0.05); and (2) women with different education levels had statistically significant differences in tumor size, post-operative ER, PR and Her2 status, and post-operative chemotherapy, radiotherapy, and endocrine therapy (P < 0.05). In Xi'an, China, women in low-income occupations or with low education levels are more likely to have advanced tumor stages at presentation, lower implementation rate of clinical breast examination, and less treatment.

Understanding the nature of science (NOS) has been a major component of scientific literacy and an important learning goal in science education (American Association for the Advancement of Science, 1990, 1993; Millar & Osborne, 1998; National Research Council, 1996, 2013). To achieve this goal, it is necessary to include appropriate views of the nature of science in science curriculum such as a textbook. The aim of this study was to conduct a content analysis of the elementary science textbooks to examine the presentation of the nature of science (NOS) using the four themes of scientific literacy, which are (1) nature of scientific knowledge, (2) nature of scientific inquiry, (3) nature of scientific thinking, and (4) nature of interactions among science, technology, and society (STS). Findings show while $3^{rd}$ and $4^{th}$ grade levels of science textbooks heavily emphasize on the Theme I, nature of scientific knowledge and the Theme II, the nature of scientific inquiry, the upper grade levels such as $5^{th}$ and $6^{th}$ grades of science textbooks are well balanced with the four themes of the nature of science. In addition, most of elementary science textbooks little focus on the Theme IV, nature of interactions among science, technology, and society (STS) among the four themes of the nature of science. It might be a shortcoming because the understanding the nature of interacions among science, technology and society (STS) is one of the key components in order for students to be a scientific literate person.

Several laboratories worldwide have demonstrated the feasibility of producing amorphous silicon thin film transistor (TFT) arrays at temperatures that are sufficiently low to be compatible with flexible foils such as stainless steel or high temperature polyester. These arrays can be used to fabricate flexible high information content display prototypes using a variety of different display technologies. However, several questions must be addressed before this technology can be used for the economic commercial production of displays. These include process optimization and scale-up to address intrinsic electrical instabilities exhibited by these kinds of transistor device, and the development of appropriate techniques for the handling of flexible substrate materials with large coefficients of thermal expansion. The Flexible Display Center at Arizona State University was established in 2004 as a collaboration among industry, a number of Universities, and US Government research laboratories to focus on these issues. The goal of the FDC is to investigate the manufacturing of flexible TFT technology in order to accelerate the commercialization of flexible displays. This presentation will give a brief outline of the FDC's organization and capabilities, and review the status of efforts to fabricate amorphous silicon TFT arrays on flexible foils using a low temperature process. Together with industrial partners, these arrays are being integrated with cholesteric liquid crystal panels, electrophoretic inks, or organic electroluminescent devices to make flexible display prototypes. In addition to an overview of device stability issues, the presentation will include a discussion of challenges peculiar to the use of flexible substrates. A technique has been developed for temporarily bonding flexible substrates to rigid carrier plates so that they may be processed using conventional flat panel display manufacturing equipment. In addition, custom photolithographic equipment has been developed which permits the dynamic compensation of substrate distortions which accumulate at various process steps.

Internet websites are excellent resources for younger people to gain information related to breastfeeding. So in this study, we evaluated the breastfeeding knowledge of university students, as well as the currently available website information on breastfeeding. Among the criteria, the six most important evaluation categories for the breastfeeding information on websites were selected and identified. The study participants completed the modified Williams and Hammer's tool, in order to evaluate their breastfeeding knowledge. An additional tool took into consideration the website breastfeeding information criteria, to evaluate the Korean websites. This 34 item tool was categorized into milk supply, comfort during breastfeeding, health of the baby and mother, social support, presentation of message, and products or financial motivation. Thirty-seven websites related to breastfeeding were evaluated, and the results were then discussed by nursing students. The students in this study were not knowledgeable on breastfeeding management with regard to the expression and storage of breast milk, the prevention and care of sore nipples, or use of breastfeeding aids. The breastfeeding information found on the Korean websites received positive evaluations for milk supply, comfort during breastfeeding, and health of the baby and mother. However, the educational content on social support, the message presentation, and the product areas on websites were rare or required additional information from breastfeeding specialists. In conclusion, based on our empirical survey, we need to design websites and evaluation tools for accurate website information regarding the social and economic benefits of breastfeeding, so that Korean women are better motivated to breastfeed by the information they obtain through the Internet.

A Vehicle Tracking System consists of GPS tracking device which fits into the vehicle and captures the GPS location information at regular intervals to a central GIS server, and GIS tracking server providing three major responsibilities: receiving data from the GPS tracking unit, securely storing it, and serving this information on demand of the user. GPS based tracking systems supporting a multi-session processing among RMA, RM, and RCP can make a quick response to various services including other vehicle information between RSU and OBU on demand of the user. In this paper we design RSU lower layers and RCP applications in OBU for a multisession processing simulation and test message processing transactions among RMA-RM and RM-RCP. Furthermore, we implement the additional functions of handling access commands simultaneously on multiple service resources which are appropriate for the experimental testing conditions. In order to make a multi-session processing test, it reads 30 resource data,0002/0001 ~ 0002/0030, in total and then occurs 30 session data transmissions simultaneously. We insert a sequence number field into a special header of dummy data as a corresponding response to check that the messages are received correctly. Thus, we find that GIS service system with a multi-session processing is able to provide additional 30 services in a same speed of screen presentation loading while identifying the number of session processing of Web GIS service, the number of OBU service, and the speed of screen presentation loading by comparing a single session and a multi-session of GIS service system.

XML architecture is important to wireless or wired presentation. It is also important for data exchange between businesses. XML forces the separation of content from style and gives wired or wireless devices flexibility for interpretation. Separation of content, style, and logic is key to advanced architecture. XML can be exchanged among databases on multiple systems with presentation on wired or wireless devices. An XML schema might need to be defined, or an established DTD might need to be transformed to access a relational database on the server. The purpose of this study is to generate XML documents such as DTD, XML schema, RDB mapping using Tagfree's XML developer tools in order to experience whole processes mentioned above. Overall understanding of data structures of and database processing with XML documents, which is essential to XML programming and database processing, can be accomplished with this study without much endeavor to learn complex XML syntax. The future study can be extended on the subject of web programming with DOM or SAX API.

Reading activities and after-reading-programs were appled to students of 4 school years from 2 to 5 school year who read subject books separately, in order to activate reading activities after reading. After-reading-programs make, supply and utilize analytical reading materials of subject books for 5 days of reading camp and that consist of composition of impressions of the book, presentation of that reading discussion and a picture of impressions of the book. The results show that most of all composition describing their impressions of the book contributes to activation of reading activities after reading very much among four types of after-readings. The next reading discussion is effective and presentation Is also good. But a picture of their impressions of the book does not vet promote activation of after reading activities.
