This article describes the status of science teacher education in Taiwan. The pre-service and in-service science teacher training system, institutes, curricula, programs, and evaluation on the institutes were briefly introduced. The differences before and after the 1996 reform of science teacher training system were compared. Finally, the attempts and efforts that have been done through the channels of research to promote science teachers' professional development were addressed. These efforts include the Case studies of exemplary science teachers' teaching performances, the development of licensure instruments for the certification of science teachers, the use of computers and distance education for supervising student teachers, the exploration of promoting science teachers' understanding about the nature of science, the exploration of promoting science teachers' pedagogical content knowledge, the exploration of promoting science teachers' ability of increasing effective student-teacher and student-student interactions, and the exploration of effective teaching strategies.

To promote the efficiency of production process of small and medium sized company, government conducts production information business that collects and analyzes information of production field automatically and helps process' controlling and supervising by supporting costs of purchase, installment, etc. of hard-software and network related to middle and small sized company intending e-Manufacturing of production field with computer and information & communication network. As a result, the number of middle and small sized companies that introduce and manage production information system is increased. Therefore, the purposes of this research are to arrange contents of production information system introduced to solve current problems of middle and small sized companies and analyze effects of small and middle sized companies' introduction through example companies.

In this paper, we added that developed communication control system between the PLC of pressure machine and the control computer, and developed a new protocol in order to communicate between the PLC signal of pressure machine and the control computer. This communication control systems play an important role in transforming the PLC vendor self-interface type and between computer and PLC. This system has PLC access function to control computer on the backbone network, and then could be operated by PLC through this system. The benefits we can obtain by developing this communication control systems are as follows; First, we can improve the quality of goods and the management of materials using the communication network and then implement the centralization management. Second, we can decrease manpower for production. Finally, we can maximize the company's profit with the increasing productivity by supervising the equipment wrong workings in the central.

A traditional clerkship consists of a series of short rotations in specialty disciplines and is usually based in tertiary, urban teaching hospitals. Shortened inpatient stays and the shift toward ambulatory management have had a negative impact on student learning. There have been growing concerns that the traditional specialty-based clerkship in fragmented and highly specialized clinical environments may not be the optimal choice for basic clinical education. As a result, a new model of clinical clerkship called longitudinal integrated clerkships (LICs) has emerged. There is increased interest in LICs due to the growing evidence of positive outcomes for students, patients, and supervising clinicians. Emphasizing continuity as one of the main organizing principles of an LIC, this article reviews the introduction of LICs into medical education, the key concepts and educational theories which underpin LICs, and the typology of LICs. The author also offers some personal suggestions for contemplation before clerkship programs in Korea adopt LICs.

The present study in the view of humanistic psychology was attempted to seek the purpose of study, the relationship between nurses′working efficiency that measured by an observational working efficiency scale and their subjective perception. "Perceptual orientation scale"(Choy, Chung Hoon 1971) was administered to 100 nurses during the Period of May to July 1972, and the relationship with their ratings by their supervising head nurses. Educational background, ages, and their lengths of caller were compared with their subjective perceptions. All the relationship were calculated by the method of chi-squares and correlational coefficients. The results of this study are summarized as follow: 1. There is no significant relationship between nurses′subjective perceptions and their working ratings. 2. There is significant relationship between nurses′subjective perceptions and their educational backgrounds. 3. There is no significant relationship between nurses′subjective perceptions and their lengths of career. 4. There is no significant relationship between nurses′subjective perceptions and their ages. The results of the present study are interpreted to the sampled research group of this study and are not to be extended to any other groups.

We are now using separate ID Database, Permission System, OS and Standard Data Format in PC, Cell phone, IPTV service and these are not good in many kind of usage, data sharing, contents servicing and supervising efficiency To merge these multiple services into one system we need to make a single ID systems for all and this paper will gide you to the new ID system that was much better than the old one. This new type of ID system is made with 3D Data and this will give fantastic visual effect & rich information data to the ID users in 3D way which is much better than 2D image & Text information technology.

Directional elements are fundamental to protection scheme security and selectivity, performing such critical tasks as supervising distance elements and controlling overcurrent elements. But, conventional operating principles for directional detection based on negative or zero sequence quantify do not satisfy the requirements for improved sensitivity and fast operation under any fault conditions. In this paper, new algorithm for directional elements is proposed. The proposed algorithm use the positive-sequence superimposed voltages and currents in order to be used in all fault conditions. Also, because this algorithm uses a voltage compensation method. it can be well operated under strong source conditions.

This paper addresses the design and implementation of a wireless network. proposed as a cost-effective support platform for PLCs. With this network. one or more supervising stations may access remote equipment like PLCs. An applicable communication methods are described and we applied efficient method among them to PLCs communication. The paper specifies these requirements and indicates methods to fulfill them. Also. it provides to the model of operation, and focuses on the implementation approach. The hardware and software design is described together with a number of critical points related to wireless communication on the Cnet. Furthermore, a discussion on system expandability and performance is tackled and some observations are stated. The main conclusion is, that the proposed method can feature good performance under normal operating conditions.

A virtual reality system is implemented for the operator supervising a robot's operation at a remote site. For this implementation, a two D.O.F force-reflective joystick is designed to reflect the force/torque measured at the end of robotic manipulator and to generate the motion command for the robot by the operator using this joystick. In addition, the visual information that is captured by a CCD camera, is transmitted to the remote operator and is displayed on a CRT monitor. The operator who is holding the force reflective joystick and watching the CRT monitor can resolve unexpected problems that the robot confronts with. That is, the robot performs the tasks autonomously unless it confronts with unexpected events that can be resolved by only the operator. To demonstrate the feasibility of this system, a remote peg-in-hole operation is implemented and the experimental data are shown.
