The purpose of this study was to change practical korean costume in 20C. In the early 20C, inflow of western civilization started to change korean costume. Since then gradually changes to be simple in Korean costume. Results of this study can be summarized as follows: Traditional jacket (jeo-go-li) gradually began to be long to waist line. This jacket length was to be long and it sleeve is to be short in early 2OC. Traditional skirt (Chi-rna) length was short to the calf of the leg. Traditional wide skirt was gradually to be narrow and pleats shape look as if it in go-gu-Ryeo Dynasty. The width of pleats was about 3~5 cm, be one-sided, look as if it western style in today. But pleats skirt already existed on a women's of the upper classes in go-gu-Ryeo Dynasty. Women's long Coat (do-lu-ma-gi) length was short to under hip line in late 20c. In this way, the practical idea, the factor of design was because of western idea in civilization ages, early 20C. Since then gradually reformed to be simple in Korean costume. Assuming that the trend of simplification in Korean costume is related to the idea of practical. Therefore Korean costume of living or a reformed Korean costume to be design of practical, functional, convenient, economically. And it must have to traditional idea, it is only beauty of shape, pattern, line, fabric in Korean costume.

The purpose of this study is to identify the current state of coding education for children and to propose a new 'play-oriented' educational content to keep up with the problems of education in line with the revision process of the 4th Industrial Revolution. As a research method, we investigated and analyzed the case of the Korean early childhood coding education program, and then suggested the direction of the future infant coding education and suggested a new play area for children. Case analysis shows that current coding education places many restrictions on children's activities. So we propose a coding education space as a 'playing space' where children can actively play. Because the space is used, emotional education is possible because it can stimulate senses such as vision, touch and smell. In addition, this study is expected to cultivate not only spatial comprehension, but also imagination, creativity and cooperation. In future research, we will study the characteristics and technical process of children in-depth to help develop early childhood education.

The study is to suggest the example of convergence capstone design operation in department of early childhood education at a college and intellectual property rights application and registration. Based on key experiences such as practical training, students derived ideas for solving problems across the field related to young child, and overlaps with existing intellectual property rights ideas were verified. Linkage with industry and engineering experts was established for mentoring, after going through a refinement process, it contains the process by which five teams among the winning works of the school competition achieved the result of patent application and registration. Through this, we revitalize convergence capstone design education that goes beyond a creative and practical competency-centered curriculum and is linked to the performance of securing intellectual property rights.

In Korea, the interior design of urban electric railcar has been changed based on the requirements of railway operation company. However, most of the designs are similar to Japanese style owing to the Japanese technical cooperation in early stage of manufacturing in Korea. In order to present the direction of interior design of Korean electric railcar, we have investigated and analyzed the interior design of Japanese electric railcar.

This paper describes a requirement analysis for automotive engine design using a computer aided systems engineering tool RDD-100. Because the engine is a complex system with many subsystems, there are many needs of stakeholder throughout the life-cycle of the engine. The originating requirements have been derived from the needs and decomposed into leaf-node requirements with the tool. Many requirement errors have been detected during the decomposition process and resolved by modifying the requirements. Inconsistency problems have been also resolved with the tool, Analysis of engine requirements using RDD-100 brings clarity to engine design early in the development process.

The injection molding process is analyzed to get the information on the mold design parameters and the optimum process conditions for automotive plastic front fender. The gate position, runner size and cooling channel are determined by the estimation of the flow balance, packing time, uniform cooling and shrinkage and warpage in the injection molding analyses. The procedure can be used in the mold design in the early stage when developing plastic parts.

Fire engineering design method based on structural performance of buildings has been developed through all of the worlds since the early 1960's. But recently the worlds have been changed rapidly in aspects of global community and mutural free trade circumstances. Therefore the concepts of fire design on structural performance need to harmonize among countries that have their own unique regulations and ISO TC 92 and SC 4 have worked in order to make the united international standard.

Generally, the frame design of a vehicle is a critical technology that plays an important role in the racing and high performance sports car market. The high performance of race car frame means that it requires high torsional stiffness because it directly affects the cornering behavior of the race car. The optimal design for the frame of a low-cost single seat race car was carried out using the DOE (Design Of Experiments) with Taguchi's orthogonal array and FEM (Finite Element Method) analysis to secure sufficient torsional stiffness in this paper. According to the results by DOE and FEM analysis, the optimal design case produced improved 10.7% and 14.5% improvement in each stiffness-to-weight ratio and frame weight than in the early design step. Therefore, this paper shows that the optimal design with Taguchi's orthogonal array is very useful and effective for designing a tubular space frame of a low-cost single seat race car in the early design step.

The analytical models and algorithm of the SPIKE code, which has been developed by KAERI's KALIMER team to investigate the sodium-water reaction phenomena in the liquid metal reactor, were introduced with its verification calculation results. The sodium water reaction of KALIMER IHTS was evaluated. Early stage of the sodium-water reaction consists of wave and mass transfer regimes. The pressure variations were independent of specific design features in the wave transfer regime. However in the mass transfer regime, the pressure variations were strongly dependent on cover gas volume and rupture disk set pressure. The early stage SWR analysis showed that the KALIMER IHTS with an appropriate cover gas volume and rupture disk set pressure had enough margin to its design pressure.

This Study is concerned with the acceptance of Western timber structure and the interior space of church buildings in the early modern period in Korea. Timber roofs have represented a wide variety of constructional forms and have been fundamental to any technological appraisal of the evolution of both of Western and Eastern architecture. Especially the roof structure of the church buildings reflects the technological level, aesthetic sense, and spacial concepts of the age. Between Western timber structure and Korean timber structure, there are many differences in not only structural form but also form of roof, members, load, frame system and etc. And there were various types of framing technique such as timber truss, timber arch, timber vault in the western style church architecture in the early modern period in Korea. I have summarized the character of the acceptance process of Western timber structure and the influences on the interior space of church buildings.
