In the TV manufacturing industry, a demand for chic design of TVs is increasing. As a reult of this trend in TV design, more curved surfaces in a TV cabinet are introduced, which enforces the use of fixers to combine a front cabinet with a TV main body. In this paper, we introduce a robot system for attaching various types of fixers to a TV cabinet. The developed system consists of three main blocks. The first one is the dispensing block, in which transferred cabinet is centered and UV adhesives are dispensed on the cabinet. The second one is the fixer attaching block, in which a cabinet is centered again and fixers are attached to pre-determined places on a cabinet by a robot with several end effectors. The last one is the UV hardening block, in which very strong ultraviolet rays are applied to the cabinet for attaching fixers tightly to the cabinet. The developed system is successfully adopted in a TV manufacturing process.

A cabinet is an outer frame of a TV, which is usually made of poly-carbonate. Cabinets are apt to be deformed because of applied heat during injection molding process and UV joining process. Severely deformed cabinets cause a falling-off in quality of the final product. Therefore cabinets should be inspected and only the good ones should be delivered to the following process. We implemented an experimental system for shape recognition of a cabinet and proposed several indices to characterize the shape of a cabinet. We also proposed algorithms to eliminate the possible bias present in measured data and to check the goodness of a cabinet. Experimental results show the feasibility of the propose algorithms.

In this paper, we introduce a fixer attaching robot system which is used to attach several fixers to a TV cabinet. It is necessary to automate the fixer attaching process for two reasons. One is that the process is very harmful because very strong ultraviolet rays are used in that process. The other is that the productivity and the overall quality of the end-product are determined by the fixer attaching process. We proposed 9 candidates for the robot system to be used in the fixer attaching process. Then we simulated cycle time for each of the 9 candidates with considering physical constraints. We also considered other aspects such as the easiness of implementation, possible interference with other mechanical structure, and cost etc. to choose one of the 9 candidates. We implemented the chosen robot system and adopted it in a TV manufacturing process.

TV microphonic phenomenon (black patterns overlapped on the image when TV sound is set too high) was studied experimentally. It was found that this phenomenon was due to the vibration generated at speakers, and transmitted to the CRT through the TV cabinet structure. Based on this fact, a simulative study was carried out on the assumption that the vibratory motion of the shadow mask located in the CRT could cause the landing error of electronic beam. The result of the simulation corresponded qualitatively with experi- mentally observed facts.

Thanks to the recent apartment housing sales in new cities and metropolitan area, the public-use furniture market is greatly animated with the development of customized furniture. Nevertheless, the situation becomes difficult because of the fierce competition among the furniture suppliers with quoting at the lower price to get the order. In order to produce unique and stylish living cabinets, it is required for the furniture designer to create the design under the systematic design process collaborated with the construction company and make the design proposal thereby to the construction company. The present paper is focused on the re-usability of TV set currently possessed by the tenant, variability, uniqueness, pricing level suitable for the cost of real estate sales, modern design and so on. in the development of apartment living room cabinet. Thus, it is important for the furniture supplier to realize the importance of the design field in order to enhance the competitiveness of the customized furniture in the apartment housing. Accordingly the present researcher has developed the modem variable living room cabinet in accordance with the systemic design process by realizing the leads of tenant of the apartment housing and then establishing the concept focused on the design required by both the tenant and construction company.

The Plan for effective usage of living room must be suggested because families primarily use living room for public space. And from the viewpoint of function and decoration. the kind of furniture. furniture occupancy quantity. and the arrangement of furniture have much affect on using a dwelling space. So this study will suggest basic data for a good furniture usage through experiment using scale down models. To analyze the data. frequency and percentage were used by running SPSS $PC^＋$ program. The major results are as follows. In an experiment using living room and furniture models(Scale 1/20). according to the size of space. TV sizes and furniture occupancy quantity were in proportion to size and space of the living room. Also they chose various types of tea-table and side-tables. In small spaces. subjects chose simple arrangement types (no sofa or I type sofa and cabinet). but in large spaces. they chose \ulcorner type or \ulcorner type sofa and cabinet.

In the structure of modern houses, a living room is the space most frequently used by family members. In a living room, they rest, talk together, watch TV, study, read books and enjoy hobbies. A living room is furnished with a TV cabinet, a storage closet, a sofa, a bookshelf, a desk and etc. depending on the purposes of activities in it, which can be different in each house. Furniture is the required tool for indoor architectural space and humans to lead a life. In most families, a man and a woman marry each other and become man and wife, go through the honeymoon phase, give birth to one or two children and become a family with three or four members. According to the children's growth cycle from birth to infancy, early childhood, childhood, adolescence, youth and adulthood, furniture layout and kinds of furniture in a living room change. Depending on the family life cycle, most parents of young children try to help their children to form good habits of reading books and studying for their future. As for the environmental elements interrupting reading and studying, watching TV and using smart phones excessively are being regarded as problems. As the number of two-income families is increasing in this era when many women are participating in the social activities with the government's encouragement, children are having more time.

This paper deals with the effective protection method for the household electric appliances against lightning surges invading from the Power lines. Direct or induced lightning is the main cause of the breakdown of household electric appliance. The most effective protection method is to install SPDs(surge protective devices) at household electric appliances. If SPDs were not installed at most household electric appliances, it is necessary to install SPDs on the mains. Therefore the propagation aspect and protection methods of lighting surges coming into household electric appliances through the mains was experimentally investigated. The in actual-sized test circuits results of protection method for 8 household electric appliances including computer monitors and TV set could be summarized as follows: The breakdown characteristics of household electric appliances from lightning surges were significantly changed with the their input impedance. Namely, the types of input impedance are classified into infinite, resistive or inductive impedances. Especially, the monitor for computer with inductive input impedance from lightning surges was relatively weak against lightning surges. It was confirmed that the self inductance of branch circuits on the mains have protection effect for household electric appliances against lightning surges invading from the power lines. Also the varistors installed at cabinet panel or circuit-breaker were more effective than multi-tap outlet with varistors. When installed varistors in cabinet panel and multi-tap outlet together, the surge protection effect is much more excellent in technical and economical aspects.

Many ethnic groups have different cultural backgrounds and each culture has developed with its own traditions. The interaction between different cultures is getting more active through acculturation and cultural contact. The purpose of this study was to provide basic data about the domestic living of Australians in order to compare with Korean immigrants in the form of a Cross-Cultural study. For this, usage of domestic space and seating style of 53 Australian households in Melbourne were analyzed. Ethnographic research with questionnaire was used. The results of the research were as follows. 1. The open plan type combining the kitchen, dining and tying areas was the most popular one for Australians and they are very satisfied with that type. 2. The laundry room has been planned traditionally and Australians demand to be able to dry their laundry and do ironing in there additionally. Most of Australians were satisfied with separated toilet and bathroom. h drain hole on the floor of the bathroom was not essential for most Australians. 3. Australians were doing various activities in the living areas and they also enjoy gelling together in the kitchen and dining areas. 4. The seating style of Australians was generally the chair-seating style. However, they sometimes made a bed for guests on the floor and watched TV and treated guests with both chair seating style and floor seating style. 5. Australians were satisfied with using carpet presumably for its warmth.6. Many Australians took off their shoes inside of the house for hygienic reason. Most people organized the shoes in the cabinet of the bedroom. 7. The most popular heating system was ducted heating for Australians and they were very satisfied with it because it was suitable for the weather in Melbourne. 8. The living room was the most important one for Australian families and they thought that it should be decorated well for entertaining guests. It was also considered that brightness of the light was enough for most Australians.
