This study reviews studies that used skin temperature in order to establish an emotion evaluation protocol based on skin temperature for home appliances. A survey of skin temperature evaluation papers was conducted by the following five stages: (1) keyword search, (2) title screening, (3) abstract screening, (4) full paper screening, and (5) relevance evaluation. Selected papers were reviewed for: purpose, recruitment criteria of participants, the number of participants, apparatus, procedure, measures, analysis methods, and major findings. Thermistor sensors and thermography are used for the measurement of skin temperature. Skin temperature sensors are attached to 4 - 10 locations on the body and their mean of skin temperature is calculated by Ramanatan's 4-point or Hardy & Dubois's 7-point method. Semantic differential (SD) method and thermography measuring facial surface temperature have been used for emotion evaluation. The SD method provides a set of adjective pairs related to a product and evaluates changes in emotion from the use of the product. The range of facial surface analyzed is defined in the thermal image and temperature changes before and after the evaluation are analyzed. The evaluation items of home appliances include form, color, material, aesthetics, satisfaction, novelty, convenience, pleasantness, and excellence. Many existing emotion studies using skin temperature do not apply physiological and psychological methods. This study provides basic data to establish a skin temperature and emotion evaluation protocol by examining literature for skin temperature and evaluation of sensitivity.

The purpose of this study is to clarify which some factors among the socio-demographic factors have effect on the housewives behavior on how to buy small electric appliances and how to use them. The questionnaires were distributed in July 1985 to 491 housewives in Seoul. Satistical methods as percentage, frequency, arithmetic mean, chi-square test, t-test and F-test were used for data analysis. RESULTS : 1) The average rate of possessing the automatic rice cooker is 87.8%, the electric frypan is 81.0%, the toaster is 36.9% and the blender is 86.9%. 2. Generally the frequency of use were low. 3) Generally their knowledge on small electric appliances is low. 4) The ability of management in blender was influenced by age, education and in automatic rice cooker was influenced by only education.

Rapid increases of bulky home electric appliances such as televisions, refrigerators, washing machines, etc are about to create many problems in their waste management in Korea. This paper summarizes the present status of the discarded appliances treatment including the estimations of their quantity, constituent materials, and recyclings.

This study attempts to explore and explain major socieconomic factors which determine the extent of rural consumers' external search behavior in cases of two product categories: electric appliances and clothing. For the purpose of this study, interviews were conducted with 201 home managers in four rural towns(Hwasun, Haenam, Naju, and Bulkyo) of South Cholla Province. On the whole, the hypotheses that socioeconomic status, age and the characteristics of region of rural consumers make significant differences in their shopping motivation and the extent of external search are generally supported in case of clothing. No substantial differences are found in case of electric appliances. This study suggests that the effective purchasing system and the providing of informative consumer information would be needed to rural consumers for their extensive search. It also suggests that psychological aspects and situational variables in addition to socioeconomic aspects presumably contribute to our understanding of search behavior.

In this paper, a home network access agent, which controls and monitors networked appliances at home using various terminals regardless of user's location, is designed and implemented. The proposed access agent integrates wire and wireless network on a home gateway (or home server) and is accessed with consistent messages using various terminals such as a web terminal, a PDA and a cellular phone. Also, in order to verify the operation and availability of the agent, a user interface for the various terminals is designed and a home network testbed which is accessed and controlled by the terminals is implemented.

With a home network, a device can dynamically join a home network, obtain an IP address, convey its capabilities, and learn about the presence and capabilities of other devices. Devices can subsequently communicate with each other directly. Device discovery protocol defines how network services can be discovered on the network. In this paper, we propose the secure discovery method of devices that uses mutual authentication with symmetric key between devices. This method that we present distributes symmetric-key to home network devices by the home server. Using this key, mutual authentication is performed between home appliances. It enables any appliance under any middleware's control to securely communicate any other appliances.

The traditional way for convergence of smart appliances was software integrations on middleware. It is possible advantage to integrate easily and quickly with this way. But basically the middleware approach is slowly executed as it is huge the size of software. To solve this problem, we suggest a modeling tool for convergence. As we can execute and generate the automatic source code at the design phase with our modeling tool, it is possible to do software integration without the middleware. We use one example of U-Home environment to show the convergence for TV and the door lock system. With our approach, we will be able quickly to develop the convergent products what the customers desire with inexpensiveness, that is, the convergence of smart appliances without the middleware.

In spite of increasing public concern about the human exposure to electric and magnetic fields(EMFs), there is little information about the EMF levels in the vicinity of power facilities and of home appliances. To provide such information, a nationwide survey for EMFs near overhead transmission lines has been conducted. The median values of the electric fields and magnetic fields of 153 transmission lines were 0.47 kV/m and 11.6 mG, respectively. The maximum values were 3.16 kV/m and 125 mG. These were low values in comparison with any EMF guidelines or standards of advanced contries. Measurements of the magnetic fields of typical home appliances and daily human exposure records have been also conducted. These magnetic field values were comparable to those of the transmission lines.
