Korean elementary school facilities are a lot of changes since the mid-1990s. Creative learning ability to become more important. Interior space environment and the hardware changes needed improvement. In this study, depending on the teaching methods and curriculum characteristics to suggest design guidelines for a more effective lesson plan by changing the terran out. Open education free to enhance the development and creativity of the human spirit, the human, and realize the value of education is to increase the relevance of education for self-realization and social. Space for open educational practices through advanced layout is proposed. There is a need for the development of new school furniture for a variety of lay-out. It is important to develop a spatial variability in new school furniture.

The purpose of this study was to examine variables affecting fashion consumer ethics. 202 consumers living in Seoul and its suburb participated in this study. Data were analyzed by using descriptive statistics, factor analysis and multiple regression for this study. As the results, consumer ethics was classified into three factors such as 'Purposely illegal behavior', 'Tacitly illegal behavior' and 'Socialized illegal behavior' factors. Second, regarding ethics judgement, machiavellianism only had affected consumer ethics. Results showed that 'Tacitly illegal behavior' and 'Socialized illegal behavior' of consumer ethics affected consumer ethics on Fashion Products. Finally, results of multiple regression revealed that psychological factors such as compensatory purchasing, materialism and propensity of religion accounted for 19% of the explained variance in fashion consumer ethics. Based on these results, a fashion educational program about consumer ethics related to fashion industry would be suggested.

This is the review of 2,500 cases on the trend analysis of technology and market. We find the fact that the patterns of trend analysis are defined by the purpose and size of the series and analysis, not by the difference of experience, educational background, country or organization. Based on these facts, we define 14 types of the analysis of technology and market. Also we conceptualize several patterns of the analysis in methodology, techniques, analytical index, structure, information source and the value by types of trend analysis.

Currently, there has been a special practical program in Transmission for developing country(Southeast Asia, China and the Middle East) in KEPCO..And it will enhance the value of KEPCO by having highly competitive practical programs compare to other electric power company in developed countries. In this program, we focused on actual affairs to help engineers become experienced and all lecturers-experts in practical work-are giving the know-how of technique and skill..This program consists of 16 courses(Power system, Transmission construction and maintenance )which is designed for customers own needs. Therefore anyone can make the order of the course as they need. This program has contributed much to the growth of the company and helped to achieve a world-wide reputation. Also foreign aid project created a KEPCO image which will enjoy the nation's love and confidence. Through this course we can increase our international competeitivenessand and will have a chance to start a business that has a future in Northwest Africa.

This study is to investigate what students want to learn and what mathematics teachers should teach in their classrooms. 1314 students and 527 mathematics teachers were randomly selected to administer the questionnaire. The result shows that their is a considerable mismatch between students'learning desires and teachers'teaching practices in classrooms. What students want to learn is creative knowledge; however, what they learn in the classroom is ‘imitative’ knowledge. This study suggests that the overall educational goal of mathematics education in Korea should emphasize (1) learning to communicate mathematically, (2) loaming to reason mathematically, (3) becoming confident in pupils'own ability, (4) learning to$.$value mathematics, and (5) becoming mathematical problem solvers.

In this study, we developed for processing complex features using CAM software that satisfies precision for example practice and related qualification tests suiTable for CNC training purposes. In addition, functions such as location control, speed control, and processing path generation, which are the main functions of CNC machining machines, were constructed using small equipment parts, servo motors, inverters, general purpose PCs, and commercial NC software and researched with the goal of developing low-cost education equipment. In the static accuracy inspection, the degree of machine when measuring the parallelism of the X, Y and Z axes and the vibration of the main shaft did not reach the allowable value. However, we have obtained a finished product that satisfies the CNC machine book sample shape machining, detailed functions of the position control function of the CNC machine tool, linear interpolation function, circular interpolation function, and tool offset function. In the qualification test shape processing, a shape with a degree of 1/100 mm was processed to obtain position accuracy that satisfied the tolerance.

This study examined the insolvency likelihood of young debtors from the 2018 Household Financial and Welfare Survey. This study used the Household Default Risk Index (HDRI), which considers the ratio of total debt to total assets (DTA), and a total debt service ratio (DSR) to examine the insolvency level of debtors. The descriptive analyses showed no difference in frequency of households with a high probability of insolvency between those less than 35 years of age and those over 35 years of age. However, the median HDRI value for those less than 35 years of age was higher than those over 35 years of age. The multivariate analyses indicated that educational expenses for young Korean debtors was a factor that increased their probability of insolvency, while income was the only variable that decreased their insolvency likelihood.

This study aims to examine changes in teaching and learning conceptions and sense of efficacy as well as relationships between them. Data were collected from 121 Korean preservice teachers before and after a 4-week teaching practicum. The results indicated that constructivist conceptions of teaching and learning increased over the practicum period and teacher efficacy shifted as well. In addition, correlations among the constructs were strengthened over the practicum period. Interestingly, constructivist conceptions related to differentiated education were not significant, while traditional conceptions related to teacher-guided lessons were significant after the practicum. These results imply that Korean preservice teachers still place value on the traditional perspective, even though constructivism dominates the current educational policies of Korea.

In the article, an analysis of the factors was carried out, which injected into the efficiency of the function of navigation systems in the minds of unimportance. Carrying out analyzes allowing for the visibility of relevant direct adjustments to the effectiveness of the function Inertial navigation systems in the minds of non-value. The designation of the navigation system was assigned to a complex of navigation systems on ships processing of the vector of navigation parameters, so that they can be victorious in the control systems of the ship's collapse, and the safety of floating is safe.
