The purpose of this study was to determine the effects of verbal analogy activities on science achievement and science attitude of elementary students. Students consolidated lessons by making short sentences with core words that a teacher gave for scaffolding instruction. Many researches about analogies have been conducted in science education. However, most of them considered analogy as learning tools, whereas this research considers analogy as a cognitive process. To see the effects of verbal analogy activities, two groups were selected from 6th grade elementary school students; one was an experimental group working with the student-generated verbal analogy and the other was a control group with teacher-centered and textbook-centered activities. Science achievement, scientific attitudes, attitudes toward science and retention were tested after the treated lessons.

Cognitive-behavioral approach can be clinically applied to coping with stress, because cognitions are playing a central mediating role in the occurances of stress and stress reactions. In other words, cognitive distortions can be associated with causing and/or maintaining psychopathology. The goal of cognitive-behavioral approach is to help the patients identify and alter cognitive distortions and maladaptive assumptions. This approach is aimed not at curing but rather at helping the patients to develop better coping strategies to deal with their life and work. The cognitive-behavioral techniques often used in this approach include problem solving, hypothesis-testing, self-monitoring, cognitive challenges, generating alternatives to automatic cognitive distortions, self-instruction, attribution and reattribution, and techniques to control or suppress thoughts. This approach is considered to be helpful for treatment and prevention of psychiatric disorders including psychosomatic disorders, in which stress can greatly affect their onset and course.

The SRP program(stress reduction program) is reported has a good effect to patient to escape from anxiety. To reduce several symptoms due to anxiety, we performed some SRP programs to our patient who had suffered anxiety disorder. The measurement tools of patient's improvement we used are Heart Rate Variability and State-Trait Anxiety Inventory. Through this programs, symptoms and feeling of anxiety were decreased than first time and Autonomic nerve system balance was much improved. this is caused by effort of self-control meditation, mindfullness, breathing instruction and muscle relaxation program.

The purpose of this study was to examine the effects of elementary science teaching program strengthening aesthetic experiences on science learning motivation and achievement. The subjects of this study were divided into two groups. The experiment group practiced elementary science teaching program strengthening aesthetic experiences, while the control group practiced teacher guided-based instruction. The results of this study were as follows. First, science teaching program strengthening aesthetic experiences gave a significant influence on increasing the science learning motivation. Second, science teaching program strengthening aesthetic experiences gave a significant influence on increasing the science achievement. In conclusion, this study showed that elementary science teaching program strengthening aesthetic experiences gave a positive influence on the science learning motivation and science achievement in elementary school science.

Developing tailor made Multimedia courseware ensuring effective implementation of instruction strategies is a challenge that manifests in myriad problems of software design and coding. In this paper an attempt has been made to analyse and identify coding and implementation problems, in the backdrop of using two different multimedia software development tools i.e. Visual Basic and Toolbook, which underpin the development and effectiveness of use of multimedia courseware. Solutions to such problems have been discussed in context of Tool book. The examples presented in this paper are based on the experience of designing and implementation of two large scale professional quality Multimedia courseware development projects.

The safety accident is one of the formidable issues in construction field, and in order to prevent safety accident, contractors perform safety education, safety control document, meeting with labors, and safety instruction in construction phase. However, safety accident is occurred continuously, it is needed to analyze which factors are affected to safety accident. day of the week, daily construction cost, and daily work task were selected as those factors. The result in this research represented that those factors were not considered as an critical one in safety accident. Because of approach limitation to safety accident, only two case studies were collected. If more safety accident cases are gathered in future study, it will clarify the cause of safety accident and will prevent safety accident.

The spent fuel rod extracting machine is automatically operated in high radioactive environment, so high reliability of operation is required. In this paper, to enhance the reliability of this machine by providing a close monitoring capability. a real time graphic simulation method is suggested. This method utilizes conventional IGRIP (Interactive Graphics Robot Instruction Program) 3D graphic simulation tool to visualize and simulate the 3D graphic model of this machine. Also, the dedicated protocol is defined for transmission of the operational data of the machine. The real time graphic simulation is realized by developing the socket module between a graphic workstation and a machine control computer through the TCP/IP network and by dividing the 3D graphic simulation GSL(Graphic Simulation Language) program as a small sized sub routine. The suggested method is implemented while automatically operating the rod extracting machine. The result of implementation shows that the real time 3D graphic simulation is well synchronized with the actual machine according to the operational data.

In this paper we proposed the format converter design and implementation for real time image processing. This design method is based on realized the large processor-per-pixel array by integrated circuit technology in which this two types of integrated structure is can be classify associative parallel processor and parallel process with DRAM cell. Layout pitch of one-bit-wide logic is identical memory cell pitch to array high density PEs in integrate structure. This format converter design has control path implementation efficiently, and can be utilized the high technology without complicated controller hardware. Sequence of array instruction are generated by host computer before process start, and instructions are saved on unit controller. Host computer is executed the pixel-parallel operation starting at saved instructions after processing start

This study examined the effects of the inquiry model on children's scientific thinking ability and processing skills. The experimental classroom of a kindergarten in Seoul was assigned the inquiry model while the control classroom was assigned general scientific education (N=48). Seventeen treatment sessions were applied to the experimental group. Tests to investigate the hypotheses included the Sink and Float Test and a new instrument developed by the researchers. Findings showed that preschoolers receiving the inquiry model of instruction gained higher scores in scientific thinking ability and processing skills than the preschoolers in the classroom using the general scientific education model. In sum, this study proved the superior effect of the inquiry model in developing children's scientific skills and ability.
