This study carried out to analysis the characteristics of periodic changes of landscape facilities with the apartment sites in Cheongju City. The construction periods were divided into the introduction stage (the 1980s), the development stage (the 1990s), and the maturity stage (after 1999). As for the apartment sites constructed in the introduction stage (the 1980s), their landscape facilities were restricted to play and resting facilities. Some of them even were constructed without rest facilities. Since the focus was on the affluent supply of houses in the 1980s, they put a greater emphasis on quantity than quality. Entering the development stage in the 1990s, they started to pave the sidewalks and driveways separately within the apartment sites and build parking lots underground. After 1999, they entered the maturity stage, where the outside spaces of apartment sites began to reflect environment-friendly designs and the initiatives to improve residential environments. The major causes behind the introduction of high-grade materials in landscape facilities in the open spaces of apartment sites are the upgraded level of living standards and the diversified patterns of activities taking place in the open spaces. The environmental formative works were placed alongside waterscape spaces to create a beautiful and harmonious landscape.

No matter how low it might be, noise from home appliances in indoor environment cause displeasure for residents as it is produced nearby. Electronic goods including vacuum cleaner and washing machine generate high frequency noise, which interrupts TV-watching or conversations and cause noises between floors in apartment houses. In particular, refrigerators make constant noise late at night, hampering the study for exams and causing sleeplessness. Korea, despite the government's efforts to promote low-noise goods based on the noise test by corporation, there is a lack of standardization in the test method, test condition and measuring equipments. This is a major reason that lowers the reliability of low-noise products. At present, low-noise home appliances are certified with eco labeling in the nation but, only 7 brands of refrigerators, 4 brands of washing machines and 97 brands of air-conditioners obtained certification as of august, 2011. In addition, none of Kimchi-refrigerator and vacuum cleaner brands were approved as low-noise home appliances. This shows Korea's relatively underdeveloped market for low-noise products, which, in part, is because of the difficulties companies face in being certified with eco labeling as they should satisfy various requirements such as power-saving and eco-friendly design besides low-noise features. As a result, low-noise labeling for home appliances should be established for the revised noise and vibration management law and the study was carried out to establish low-noise labeling system for major noise sources including vacuum cleaner, washing machine, air-conditioner and refrigerator.

The main purpose of this research is considering further marketing strategy to resolve unsold housing matters in private sectors through an analysis of preference factors for those housing customers. This study used one of the most widely-used research methods in marketing to figure out the preference factors for those customers and then it was categorized which factors are more or less important by conjoint analysis. According to the result, the home buyers for the unsold apartments were more paying attention some social and financial benefits for instance, a decline of housing price and a guarantee of housing securities rather than geographical conditions and residential environment before they make the decision to purchase a home. Secondly, they concerned some factors such as the most importance in location and geographical condition which were easy access to the transportation. Furthermore, a standard of eco-friendly apartment buildings was essential matter in residential environment. The third, those properties were on the stocks of unsold homes so they more tended to buy their houses with lower price than the terms and conditions of housing payment. Finally, it was explored that the most efficient way to promoting them through housing exhibitions or presentations as the PR strategy.
