Due to the variety of household electric devices and different power consumption habits of consumers at present, general home energy management (HEM) systems suffer from the lack of dynamic identification of various household appliances and a unidirectional information display. This study presented a set of intelligent interconnection network systems for electric appliances, which can measure the power consumption of household appliances through a current sensing device based on OSGi platform. The system establishes the characteristics and categories of related electric appliances, and searches the corresponding cluster data and eliminates noise for recognition functionality and error detection mechanism of electric appliances by applying the clustering algorithm. The system also integrates household appliance control network services so as to control them according to users' power consumption plans or through mobile devices, thus realizing a bidirectional monitoring service. When the system detects an abnormal operating state, it can automatically shut off electric appliances to avoid accidents. In practical tests, the system reached a recognition rate of 95%, and could successfully control general household appliances through the ZigBee network.

Recently, as many next-generation appliances are become digital and intelligent, companies have come out home appliances to communicate with each other through home network. Therefore, it requires various kind of communication technology to control home appliances. In this paper, XML messages which can control home appliances such as boilers, TV etc. are proposed and defined. The XML messages sending from a home server to home appliances should be fully defined all needed information to activate and deactivate home appliances.

The purpose of this study is to figure out the actual situation of possession and use of traditional living appliances in the rural area, so as to provide plans for preservation and succession of traditional living appliances. The data were collected from 200 households in 8 rural areas classified by geographical zone. Traditional living appliances were divided into clothing.food.housing living appliances, play tools, and the others. As a result, the degree of using the traditional living appliances is 46.5%(in respect of "often use"). The need for preserving and using the traditional living appliances in modern society was 68.5%(in respect of "a little need"). The level of preservation and use of the traditional living appliances was relatively low except for food living appliances. In conclusion, the suggested directions for developing traditional goods to preserve and succeed traditional living appliances are as follows; ${\circled1}$ Developing traditional living goods peculiar to a certain locality ${\circled2}$ Developing goods with various uses; display, ornament, living appliances, memorial, etc. ${\circled3}$ Developing goods on the process and technique of making traditional living appliances. ${\circled4}$ Providing information and education on excellance of traditional living appliances.

This study is to improve reasonable consumption as a consumer and interests of the consumers through analyzing the consumer satisfaction degree on product information provided on Internet, and to present basic information to contribute in protecting consumers through preventing harms on them due to insufficient or unnecessary information. The major results of the study are summarized as follows: 1) The degree of understanding characteristics in information focus on household electric appliances provided for the consumers on Internet found to be 'average'. 2) In the degree of significancy for information of the household electric appliances, consumers recognized information regarding services most important. 3) The overall satisfaction degree on information regarding household electric appliances on Internet was evaluated through giving a weight to the degree of significancy for the products and adding the satisfaction degree by information contents, and it was found to be 'average'.

This paper presents a smart firefighting appliances monitoring system based on big data analytics platform using GS1 for Smart City. Typical firefighting appliances are fire hydrant, fire extinguisher, fire alarm, sprinkler, fire engine, etc. for the fire of classes A/B/C/D/E. Among them, the dry chemical fire extinguisher have been widely supplied and 6 millions ones were replaced for the aging ones over 10 years in the past year. However, only 5% of them have been collected for recycling of chemical materials included the heavy metals of environment pollution. Therefore, we considered the trace of firefighting appliances from production to disposal for the public open service. In the paper, we suggest 1) a smart firefighting appliances system using GS1, 2) a big data analytics platform and 3) a public open service and visualization with the analyzed information, for fire extinguishers from production to disposal. It can give the information and the visualized diagrams with the analyzed data through the public open service and the free Apps.

Purpose This study aims to investigate the factors that influence switching intention of Smart Appliances. We focuses on Push-Pull-Mooring theory and status quo bias as factors related to switching behavior. Design/methodology/approach This study developed an model to explain the switching intention of Smart Appliances and conducted structural equation modeling with AMOS22.0. To test the proposed hypotheses, we collected 319 survey responses from smart appliances's users. Findings The results indicated that low usefulness and low ease of use had an effect on the switching intention of smart appliances. The results also indicated that attractiveness of the alternative and social norms had an effect on the switching intention of smart appliances. Lastly, The difference between the relation of push effect and switching intention and the relation of pull effect and switching intention was found to be due to the level of status quo bias. The academic and managerial implications were discussed based on the results of empirical analysis.

On July 5, 1997, environmental Protection Administration of Taiwan publicized the recycling regulation of waste home appliances that include four items, namely, television, refrigerator, washing machine, and air conditioner. It is believed that this regulation pioneers the law enforcement of waste home appliances in the world. To comply with tile policy, several contemporary waste disposal plants specialized in waste home appliances were established according to a follow-up technical specification oil the waste treatment facilities and methodology. Therefore, the traditional dismantling facilities were substituted and waste collection routes were altered as well accordingly. This study investigates the collection and recycling costs of waste home appliances in accordance with these newly established routes and facilities, respectively. Cost survey was conducted among collectors and recycling plants of waste home appliances; consequently, tire collection and recycling costs were analyzed, correspondingly. Results show that the recycling costs of waste home appliances were much higher than that of other waste items. Since the market share of recycled materials is lacking, these waste recycling plants of home appliances can only survive under the subsidy of EPA in Taiwan. Due to some arduous problems, the subsidiary system has already caused serious financial unbalance for a foundation under EPA of Taiwan, which associated with waste recycling in Taiwan.
