The purpose of this study was to analysis the curriculum for educating and operating the classes of elementary science gifted in Incheon Metropolitan Office of Education. We developed the framework for curriculum content analysis based on the principles of curriculum development for gifted education. The developed framework was applied to the curricula of four classes of elementary science gifted in Incheon. And the needs of gifted students were surveyed in the classes of the elementary science gifted. The results of this study were as follows: 1. The current curriculums of two classes described the goal of the elementary gifted education, but the content and theme of the curricula of three classes were not related to the contents of the 7th national curriculum. 2. The teaching methods used in the science gifted class were mainly a lecture and an experimental activity. and there was little the process of individual instruction. 3. There was not mostly the products as the results of learning because of little performed by a project teaming, an announcement and an exhibition in gifted class. 4. Most of the students of the science gifted class were estimated by the paper tests and observation of the teacher in charge of the gifted class, not by the products and presentation etc. 5. They mostly preferred the theme of everyday life in addition to the textbook, and the instructional type of enrichment teaming and acceleration learning over the grade of themselves. 6. They mainly expected that the curriculum of the gifted class is operated during the semester.
This study was performed to investigate the degree of different stresses in university students of outer region of Seoul and to search the influence of food habit and nutrient intakes in stress. The data was collected by questionnaire method for self-diagnosed different stresses, dietary habit, and physical status and 24 hours recall for nutrient intakes. The subjects were 282 students attended at the lecture Food and Health. Diet balance was no difference with gender but food intakes were more diverse in female. Nutrient intake of male students was lower in vitamin A and riboflavin, but that of female was low in vitamin A and iron. The university students outer region of Seoul had more stress situation in frustration, deprivation and self-efface than in the stress of the noise and Type-A behavioral stress. Total self-diagnosed dietary habit score was better in the group of no susceptive overload stress than that of the high susceptive group. Same trend of dietary behavior score was in the group of no noise and anxiety-response stress than that in the susceptive groups. The quantity of nutrient intakes was correlated with different kind of stress. Niacin intake was positively related with the stress from life-events, and food induced stress. Thiamin intake was positively related with food induced stress. But the intake of iron, calcium, niacin and riboflavin were negatively related with the stress of noise. Therefore, we could concluded that different kind of stresses were influenced in dietary behavior and vitamin-mineral nutrient intakes. More research would be needed at the aspects of health promotion in the stressful situation of modern society.

As the contents of information were reinforced the rules of computer science, it was necessary to develop the new teaching and learning plans and various education materials that encourage students and easy to access. So, in this study developed a wide ran of play activities and educational materials without using a computer for the area of information representation and applied to 68 students, second grade of middle school for 4 weeks. After the class, the effect on the learning achievement was verified by the t-test. As a result, it was shown that there was a significant difference between learning with play activities materials and the traditional lecture-type. It means that learning with play activities materials in the information representation influences a positive effect to the learning achievement.
This study was conducted to investigate the concern of the primary school teachers and the teaching situation about the environmental education through questionnaire survey on the effective environmental education. The results of questionnaire were analysed and discussed to provide the effective teaching method for the environmental education. The result of this study is as follows. 1. It was found that teachers want to teach environmental lessons as a special subject, and the content of the environmental lessons in textbook was not enough in quantity, the living waste was the most serious ploblem. Owing to the lacking in materials for the lectures on environmental education, most teachers collect the material depending on the mass communication. Also they were more interested in the environmental lessons rather than the other lessons in textbook. But because of the lacking in administrative assistance, they have difficulty in conducting the effective environmental education. 2. The teaching method of the environmental education in most primary schools was a all together-type lecture in classroom. Owing to conducting the environmental education for the knowledge than the action through the extra activity, it was difficult to expect the effect of the environmental education. Also the rate of using the reflection materials which can be improved the studying effect was very low. 3. For the effective environmental education most teachers wanted the spot learnings and the case studies and teacher education and training to get an special knowledge for environmental education. The effective evaluation method for children's environmental education is to present the results by environmental experiences and practices and to formulate a system education is organized for the effective management and activation of environmental education. 4. By practising the seasonal spot learnings, students need to change of learning method and to realize the importance of environment through own self-experiences. 5. In the future, it is desirable that researching of an environmental education is offered the effective practising teaching method which is improving the development of customs and functions, cultivation of the sense of value, ability to solve the problem, to determine the intention as well as the survey on the real situation and the consciousness about environmental education.
The importance of teaching the nature of science (NOS) has been always emphasized in science education. However, the NOS is hardly taught in elementary science class. We are lacking in the strategies and materials for teaching NOS. So we designed the science drama teaching, and investigated the effects on pupils' perceptions about NOS. The subjects of this study were 185 third graders from a elementary school. The treatment group was provided with science drama lessons and the control group was provided with traditional lecture-type lessons. Their perceptions about NOS were investigated before/after the science lessons and after 3 months following them, and both of two groups were compared. The pretest results revealed that the pupils of both groups were found to have similar views on NOS. Dey had traditional views of the most items except for social construction of theories, mathematical knowledge and decision-making. After science lessons, they tended to change their views toward modem views, but the pupils of the treatment group showed more modem views than those of the control group on the observation, model, social construction of theories, predictions. After 3 months, the pupils of the control group tended to come back to their traditional views, but those of the treatment group showed tendencies that their changed views were kept up on the observation, scientific model, scientific knowledge, scientific methods, decision-making, social construction of theories, mathematical knowledge. Therefore this study suggests that science drama teaching could be one of the effective ways for teaching NOS.

Har dmaterials such as cemented carbides with or without coated layer, cermets, ceramics and diamond or c-BN high pressure sintered compact are used for cutting tools, wear -resistant parts, rock drilling bits and/or high pressure vessels. These hardmaterials contain not only hard phase, but also second consituent as the element for forming ductile phase and/or sintering aid, and the mechanical properties of each material depend on (1) the amount of the second constituent as well as (2) the grain size of the hard phase. The hardness of each material mainly depends on these two factors. The fracture strength, however, largely depends on other microstructur a1 factors as well as the above two factors. For all hardmaterials, the fracture strength is consider ably affected by (3) the size of microstructur a1 defect which acts as the fracture source. In cemented carbides, the following factors which are generated mainly due to the addition of the second constituent are also important; (4) the variation of the carbon content in the normal phase region free from V-phase and graphite phase, (5) the precipitation of $Co_3$ during heating at about $800^{\circ}C$,(6) the domain size of binder phase, and (7) the formation of ${\beta}$-free layer or Co-rich layer near the surface of sintered compacts. For cemented carbides coated with thin hard substance, the important factors are as follows; (8) the kind of coated substance, (9) the formation of ${\eta}$-phase layer at the interface between coated layer and substrate, (10) the type of residual stress (tension or compression) in the coated layer which depends on the kind of coating method (CVD or PVD), and (11) the properties of the substrate, and (12) the combination, coherency and periodicity of multi-layers. In the lecture, the details of these factors and their effect on the strength will be explained.
This study verified the effect of the experience of job-training on youth employees' wage by analyzing panal data. The study results showed that the objective of job-training(enhancing job performance, ${\beta}=.336$), satisfaction of job-training(${\beta}=.-.256$) and the type of job-training(cyber lecture, ${\beta}=.334$) significantly affected youth employees' wage. Also, age, education, marital status, hour of job-training, objective of job-training and satisfaction of job-training significantly affected the differences between groups. This study provided practical implication to prepare effective job-training policy by confirming the effect of the experience of job-training on youth employees' wage and verifying the effectiveness of job-training.

This study analyzed the effect of Chung-nam province small manufaturing firm male workers' participation in training on perceptions of effectiveness. The study results showed that Off-the-job training satisfaction significantly affected satisfaction of training system and helpfulness of self-development. It means that workers considered lecture or e-learning method is better than on-the-job training, so it is suggested that small manufacturing businesses should establish more organized training system for on-the-job training because workers' perception of satisfaction and effectiveness of OJT was lower than Off-JT. This study provided implications for verifying the effectiveness depend on the type of training and presenting important points to enhance workers' satisfaction of education and training.
Flipped Learning is being suggested which is well known as a teaching method which lets students learn the contents they will learn in advance through the advance online video and have a discussion through the team interaction in the main class for them to solve the assignment through the cooperation in a self-initiated way. Therefore, this study was intended to confirm if the flipped learning class could improve the students' learning ability and raising the interest in math by complementing the problem on the lecture-type class by applying the flipped learning class to the college basic math subject. As a result, in the unit test result, the average score of the experimental group was more than 20 higher than one of the control group indicating that Flipped Learning had a great effect on improving the learning ability, and as for the introspection journal analysis, many subjects from the experimental group showed the positive attitude toward math they felt difficult unlike ones from control group indicating that it was effective in improving the interest level.
The purpose of this study is to identify the effect of Teacher Participation-oriented Education Program (TPEP) for Elementary School Teachers to Improve Class Expertise in Science Classes with a focus on visual attention. The participants were two elementary school teachers in Seoul and taught science subjects. The lesson topic applied to this study were 'Structure and Function of Our Body' in the second semester of fifth grade and 'Volcano and Earthquake' in the second semester of fourth grade. The mobile eye tracker SMI's ETG 2w, which is a binocular tracking system was used in this study. In this study, the actual practice time, participant's visual attention, visual intake time average, and visual intake time average were analyzed by class phase. The results of the study are as follows. First, as a result of analyzing the actual class execution time, the actual class execution time was almost in line with the lesson plan after the TPEP application. Second, visual attention in the areas related to teaching and learning activities was high after applying TPEP. Factors affecting the progress of the class and cognitive burdens were identified quantitatively and objectively through visual attention. Third, as a result of analyzing the visual intake time average of participants, there was a statistically significant difference in all classes. Fourth, as a result of analyzing the visual intake time average of participants, the results were statistically significant in the introduction(video), activity 1, activity 2, and activity 3 stages in the lecture type class. The Teacher Participation-oriented Education Program (TPEP) for Elementary School Teachers to Improve Class Expertise in Science Classes can extend elementary science class expertise such as self-class analysis, eye tracking, linguistic, gesture, and class design beyond traditional class analysis and consulting.
