This paper describes an optimal design method of VSI output filter for CVCF system. The cost function is used for design, and all parameters are described in p.u(per unit) so that can be adapted to the change of CVCF rating. The capacitor current feedback scheme is proposed to control the damping ratio of the filter plant to meet the system more stable. This means that the LC resonance can be suppressed well in transient condition and can use the same control gains under the change of system capacity. The validity of the proposed method is well verified with the theoretical analysis and simulation results.

This study aims to provide visual data from analysis of the Depaysement approaches with new viewpoints to inspire and develop new fashion window design ideas. The literature and existing researches related to Depaysement were analyzed for theoretical review, and Depaysement expression approaches were identified by expression characteristics. Theme concepts using traditional Korean images, which could be applied to fashion window displays in Korea, were established, and K(Korean)-fashion design was created to develop fashion window display design. Then, the Depaysement fashion window display was executed using Adobe Illustrator and Photoshop. The results of this study are summarized below. 'Change of forms and materials' could visualize the factors inducing curiosity, which can directly stimulate the consumption sentiment lying latent in the mind of observers by assigning new values to fashion goods displayed inside windows. Unconscious experience and remarkable stories, which are not possible to encounter in an everyday setting, can be visualized through the window display in 'heterogeneous combination of objects.' 'The location change of an object' could express the refreshing and shocking scene to give weird anxiety and mental contradiction to observers by fashion window display, which could break fixed idea of human beings. 'The change of object awareness' could express contradiction and denial, which could liberate the unconsciousness lying latent inside observers through fashion window display. 'Change of spatial awareness' could create the design which maximized the fashion images of goods displayed by helping the observers to change the space of their unconsciousness selectively at their will through the fashion window display with hidden, strange, ambiguous and variable image like a riddle.

Design has been proceeding to 21 century undertaking the many-sided and complicated characteristics of the modern industrialized society much more heavily comparing to past. The rapid change of technology and media of communication faces the new concept of relationship between users and environment, and newly developed material leads designers to change the way of building concept and the process of designing. Especially the important points of user-friendly and environment-friendly approaching for designing influences over choosing, controlling meterials and forming the structure and shape organically, or simply. From the tendency of chairs designed in 1990s the very adaptable new material shows both the unlimited possibility for new design is in the turn of this century, but also it can be analogized that 'the design which can make users think' will be the philosophical basis for future desigv.

The study figures out the alternatives of training BIM design experts which is the biggest obstacle in training manpower of professional BIM designer, the largest problem when the plant introduce BIM design about the change in Construction Environment by Equipment Based BIM Design in reality of design followed by equipment based BIM design, education institution plan. BIM is the system which is built to make these information be used easier and technique which enables design construction and maintenance in 3-dimensional virtual space by designing buildings in 3-dimensional space, and by data-basing the generated information of every life-cycle information. As the essential contents of the study, educational institutions with the public authority should invest the opening of educational programs, recruit of experts and development of textbooks from a long-term perspective. And also, the role of public institution is important above all for the development of construction industry.

The constant evolution of society, culture and scientific technology, coupled with changes in life style and behavioral patterns, has led mankind to peroeive diverse needs for space. Particularly, the rapid structural change in the field of marketing has entailed changes in techinques for construction and presentation of space for an improved marketing environment. To satisfy such new, diverse needs for space, interior designers will have to redefine the "mankind and environmen( concept and examine their design methodology anew. The question of how to design available space for a certain purpose will remain a daunting task for designers in the future, as it has been in the past. In the pursuit of convenience and conformity to mankind's surroundings, every nation has, in common with other nations, basic design elements, design skills and other factors. In designing camercial space in a particular region, it is essential, however, to have a proper understanding of the social economic and cultural context indigenous to that region, as well as the impact on environmental and ecological change and marketing strategy. This study discusses design metholdology for the comming camercial space on the basis of the space concept and current status in Korea, with major emphasis on Korea's regional characteristics.

The risk of project execution increases due to the enlargement and complexity of Engineering, Procurement, and Construction (EPC) plant projects. In the fourth industrial revolution era, there is an increasing need to utilize a large amount of data generated during project execution. The design is a key element for the success of the EPC plant project. Although the design cost is about 5% of the total EPC project cost, it is a critical process that affects the entire subsequent process, such as construction, installation, and operation & maintenance (O&M). This study aims to develop a system using machine-learning (ML) techniques to predict risks and support decision-making based on big data generated in an EPC project's design and construction stages. As a result, three main modules were developed: (M1) the design cost estimation module, (M2) the design error check module, and (M3) the change order forecasting module. M1 estimated design cost based on project data such as contract amount, construction period, total design cost, and man-hour (M/H). M2 and M3 are applications for predicting the severity of schedule delay and cost over-run due to design errors and change orders through unstructured text data extracted from engineering documents. A validation test was performed through a case study to verify the model applied to each module. It is expected to improve the risk response capability of EPC contractors in the design and construction stage through this study.
