  • In this paper, the electrical characteristics of the contactless transformer is presented using the conventional coupled inductor theory. Compared with the conventional transformer, the contactless transformer has a large airgap, long primary wire and multi-secondary wire. As such, the contactless transformer has a large leakage inductance, small magnetizing inductance and poor coupling coefficient. Therefore, large magnetizing currents flow through the entire primary system due to small magnetizing inductance, resulting in low overall system efficiency. In high power applications, the contactless transformer is so bulky and heavy that it needs to be split by some light and small transformers. So, the contactless transformer needs several small transformer modules that are connected in series or parallel to transfer the primary power to the secondary one. This paper shows the analysis and measurement results of each contactless transformer module and comparison results between the series- and parallel-connection of the contactless transformer. The results are verified on the simulation based on the theoretical analysis and the 30kW experimental prototype.

  • HANSSEM is a furniture company that leads the market of residential space in Korea. The goal of this case study is to focus on how HANSSEM copes with IKEA, the world's largest furniture retailer after entering the Korean market in December 2014. IKEA's entry into Korea is possible to destroy the existing orders in the retail industry and reduce the profit of incumbent local players by realigning industry relationships. However, HANSSEM achieved rapid growth with the largest market share in the furniture market through its internal capabilities. The authors propose the main success factors in three ways: (1) residents-database including apartment floorplans in Korea, (2) high-quality human services provided by construction and A/S (After-sales Service), (3) channel diversification that provides comprehensive consultations (e.g., flagship stores, home shopping channels, stores in marts, and interior dealers). Especially, there have been various consumer needs in Korean market, such as creating their own stylish space economically. HANSSEM meets customer's needs by reinforcing the space-package (complete-interior is provided to customer in a package rather than combining individual piece of furniture) and opening showrooms, which makes customers freely experience the products and receive detailed consultations on interior designs by alleviating customers' difficulties in decorating their homes. Based on HANSSEM's outstanding activities and new investments, we look forward to seeing that HANSSEM will achieve its ultimate goal of maintaining the position of number one furniture company by attaining customer satisfaction through higher quality in Korea.

  • Interior design education has been developed rapidly since the discipline established in Korea in 1980s but unfortunately the development was without any progressive transition until 1990's. When Korean Institute of Interior Design/KIID inaugurated in 1992, interior design education and related research activities began to be intensified. Despite its effort, there were still confusion about the discipline as there were many similar discipline tracks (architecture, design, fine art, & home economic, etc.) each having an own definition of interior design and introducing different aspects of educating the subject. Education program for interior design still not sufficiently supporting the needs of today's rapidly changing industry nor to prepare the diverse needs of the client. In order for interior design major to be effective in the future and fulfill the needs of current industry development within our society, re-evaluation of our current interior design educational programs in Korea is important. This study will be the beginning of a research series. As the first part of the research series, this particular study has been focused on reviewing of current status of interior design majors in the nation and its current condition. While making suggestion for the changes in curriculum, the following points will have to be considered as basic principle. First, understanding the duality of technology and design to accommodate the contents of design discipline. Second, understanding the need of practice and theory combined for practical education. And lastly, considering ways to adopt the human experience in order to develop creativity in oneself. The focus of this research is only on the interior design discipline, and research method as the following; first, analyze current status by reviewing admission data for 2010. Second, process a survey regarding the interior design education and practice-related issues in admissions and collect opinions from educators and professional designers in the field. Thirdly, with reference to previous studies, suggestions will be made for the discipline to be effective in the field. As mentioned earlier, this study series will continue and develop to suggest improvement in interior design program as well as to provide curriculums for students get ready for the industry with more up-to-date knowledges and creativities.
