Home appliance proposes the experience of new lifestyle to consumers, together with digital technology-applied highly advanced functions, beyond its natural quality like the basic function of reducing the burden of housework. However, under the current circumstances that populations are rapidly aging, the number of elderly consumers, who feel it inconvenient to smoothly use even the basic function of home appliance, is increasing in proportion to populations. Therefore, the necessity for developing home appliance with improved usability in consideration of the elderly is rising up. This study analyzed the elderly's pattern of using home appliance and illustrated the procedure of their using home appliance, putting its focus on the home appliance that the elderly highly depend on in keeping their daily life and that they feel it inconvenient to control. And based on the illustrated procedure, this paper substituted various kinds of home appliance that were not surveyed by this study and found out 4 user behavioral models for home appliance. Same as the concept of universal design, product designs, which are convenient to use by the elderly whose physical functions are reduced, are expected acceptable to various user classes. The found user behavioral models purport to give references to design process for product planning and design solutions.

Recently, the interior design of electric home appliance stores requires comprehensive image management with systemic marketing strategies and consistence in order to attract consumers to purchase products. However, the environment of domestic electric home appliance stores is complex and confused by indiscreet design factors and operation. Despite of the fact that company costs a lot of money to manage each store, consumers are not provided with selling environment with high quality. On the other hand, it is inevitable to compete with foreign specialized stores and discount malls due to opening distribution market. Besides, company has faced to attract customers with distinct strategies in order to survive in various competition system. In this sense, in store environment, there should be consistent image in interior design of the store based on management ideology of the company for the successful management of electric home appliance stores. The purpose of this research is to investigate and analyze the case of Samsung Electronics's electric home appliance stores among domestic electric home appliance stores that is applied with Store Identity Program (hereafter SIP) and to suggest solutions for the problems. Therefore, it is purposed to use as references for the stores that has the similar interior design plan. The result of this study is to upgrade the store image through providing basic data about role of data and distinct factors for competitive design as a part of Store Identity Strategy. Furthermore, it can be important data to optimize the profits and to make positive space for both consumer and company as company and products are credible with mental satisfaction of consumers if there is enough study on SIP and process and symbol of company and products to consumers, enough recognition and improvement on problems.

In this paper, for the development of a safe and reliable DC home appliance suitable for DC home power supply system, we classified a number of inherent problems with help of the comparative analysis of existing AC and new DC home appliance. Several new technical problems of DC home appliances are mainly linked to the DC transient state. Among them, this paper concentrates on start-up inrush current problem, uni-polarity problem, and heavy DC load control problem. And to address these problems, we herein present an implementation of robust safety circuits for DC home appliances. Specifically, we investigate several multi-circuit countermeasures and select the best among them through comparative evaluation, based on theoretical, simulational, and experimental results.
