Purpose - The purpose of this research was to suggest purchasing decision factors through understanding the context of purchasing behavior and to figure out variables related to purchasing decision, purchasing cognition, and attitude. Research design / data / methodology - By random sampling, 200 consumers who are over 20, have purchased Digital·home appliance on TV home shopping, and have lived in the Seoul area were chosen as sample subjects. Questionnaires data were obtained from all subjects by self-administration method. Results - Result of analysis could be summarized as following. Analysis of the cognition of digital/home appliance product features, and influence of digital/home appliance product feature to purchasing intention are presented in the following order; price (3.50), diversity (3.10), brand (3.00). Also, analysis of the cognition of TV home shopping feature and influence of TV home shopping feature to purchasing of digital/home appliance are presented in the following order; awareness (3.63), safety of delivery (3.38), safety of transaction (3.28), product test (3.27). Conclusions - Purchasing attention of TV home shopping features presented difference in awareness, safety of delivery, safety of transaction, and product testing factors. In order to vitalize home shopping, impossibility of quality confirmation should be overcome and reinforcement of brand power should be considered.

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.

This paper describes design and implementation of home network control protocol for networked home appliances. The proposed network protocol has four-layered protocol structure and device-modem interface structure for the flexibility of modems based on power line communication. The standard message set is specified to guarantee the interoperability between various home appliances The proposed protocol can be easily implemented because it has minimum network overhead.

To date, induction motors have mainly been used for heating, ventilation, and air conditioning (HVAC) applications, however, there is significant research being done world-wide on the use of switched reluctance motor(SRM) in household home appliances. This papers proposes three phase SRM for the air-conditioner blower that has cost merit and good performance respectively compared with conventional induction motor.

Universal motors are mainly used for vacuum cleaner application. There are a lot of researches on SRM that applys home appliance throughout the world. The manufacturing cost of SRM drive makes it hard to expand its application to home appliance. This paper presents Single Phase SRM for the vacuum cleaner that has advantge in cost and performance over conventional universal motor. This paper proposes new power device driving scheme by using SRM switching characteristic. The driving scheme is very simple and inexpensive. Dwell Time Control method is used for the minimum switching loss of power device. The switching frequency of power device is less than 4.5kHz at 45,000rpm. By use of this scheme, power device based on very small switching losses can be used on SRM drive. Also, the biggest problem in single phase SRM is starting, this paper shows a new starting algorithm with two hall sensors, accelerating and running sensors, respectively. Finally, the proposed Single Phase SRM achieves higher efficiency and long life time compared to universal motor. Its life time is more than 1500 hours. Its life time is extended 4 times than that of conventional motor and its suction power is increased $20\%$ at the same volume of conventional universal motor.

From the digital perspective, customer journey and customer experience management are emerging as important issues for companies. While digital customer experience has become more important due to the recent surge in online sales of the home appliance products, customers' experience in online is not differentiated as offline-focused traditional methods are maintained. This study aims to analyze the characteristics and mutual influences of customer experiences at each stage of online purchase journey, and to explore the effects on the product repurchase intention, focusing on online purchasers of home appliance which are high-involvement products. As a result, both cognitive and affective experiences of the research phase directly affect satisfaction, whereas affective experience at the purchasing stage indicated indirect effects through cognitive experience. The experience of the research phase positively affects the next phase, the purchasing experience, and the experience of the purchasing phase leads to the intention to repurchase the product. However, it is also found that, depending on the choice of online channels, the experience of research phase may affect the product repurchase intention than the purchase experience.

With the rapid increase of recent smart phone diffusion, the convergences of home network environments and intelligent home appliances such as digital TV, internet refrigerator, DVD, digital video, communication appliance using a smart phone are highly focussed and become the recent trends in IT industry. In this paper, we design and implement home appliance control system based on the smart phone(Android) network environments. Through several experiments using Android smart phone, we confirmed that the proposed system can control and monitor indoor home appliances conveniently anywhere and anytime from outdoor.

In this paper, we present a middleware that using routing scheme that support easily for various type of network in a home network based heterogeneous network. The protocol presented in this paper, consist two layers that Network Adaptation Layer(NAL) to allow access varience networks and Network Interface Layer(NIL) to deal network dependent parts. The middleware presentedl in this paper, can easily send data to any digital appliance or receive data from any digital appliance by using our routing scheme.
