In this study, we developed RBFN(Radial Basis Function Networks) based load modeling method with harmonic components. The developed method considers harmonic information as well as fundamental frequency and voltage considered as essential factors in conventional method. Thus, the proposed method makes it possible to effectively estimate load characteristics in power lines with harmonics. RBFN has some advantage such as simple structure and rapid computation ability compared with multi-layer perceptorn which is extensively applied for load modeling. To verify the effectiveness, the proposed method has been intensively tested with various dataset acquired under the different frequency and voltage and compared it with conventional methods such as polynomial method, MLPN and RBFN with no harmonic components.

According to the change of the life environment and economic growth, the more highly a city has developed, the more concentrated is the urban function. That is, a city is required for adding more infrastructure. But, both limited land resources and financial problems made it impossible to add infrastructure. So, the necessity of multi-dimensional planning of urban infrastructure was recognized. Especially, in the urban residential area, a mixed-use of the playground of a school and the empty space of a park is desired to serve the issue of insufficient parking spaces. Schools and parks are closely connected to the center of a town, and playing a central role for the town life. For this reason, they are highly demanded in urban residential areas and also expected to be effective. However, we need to consider not only parking convenience but also the safety of users in design process, because people using parks and schools include young students and the elderly. In this study, we mainly examined physical characteristics and the utilization of schools and parks with parking facilities in urban residential areas. Then, we analyzed cases through comparing and evaluating in terms of convenience and safety. and weighed up advantages and disadvantages of each through the comparison of the schools and the parks having parking facilities. The results of this study are expected to provide fundamental references for preparing design standards for such facilities.

A demand of public using building in rural residential area changes over times. With the changes, the function and the scale of the public using building are also changed, the building is more influences on people in rural area. However, the most of facilities have been focused on the agricultural productions, and thus the facilities of health care, culture, and daylife supporting were not enough comparing to the facilities in urban area. This study surveys the facility and grasps the current status and problem of 37 rural residential area. In addition, three different revitalizing plans of public using building as a current availability and plan for use are suggested. A new community center where is expected that the public usage is increased should be managed intensively regarding an air conditioning, and waterproofing work, while an old community center and the warehouse where are expected that the public usage is decreased, but have locational advantage should be used as a rural life experience facilities and a accommodations with remodeling unless the safety matter A parking lots are considered that the availability is gradually increased and needed for public while it is difficult to get a new available site because of the ownership. Therefore, it is national decision to secure the site by removing the discarded facilities.

Nevertheless, the problem of aging cannot be treated as a problem of individuals or social burden. Because Every mankind sometime will be the person directly involved the aging. Methods : Korea, predict to reach the aging society with over 20 percent of elderly in the whole population in 2020, should find an active political plan for responding. Because a previous discussion about the aging phenomenon focused on social welfare, the housing plan for the elderly with a consideration of the physical environment for sustaining elderly's life with happiness will be primary task. Results : This research considers housing policy, focusing on the medical service. It is because statistics, which 85 percent of elderly people suffer from chronic diseases because of physical aging signify the importance of medical service to the elderly in every-day-life. Implications : We prescribe the elderly as a population over 65. In this duration, the elderly retirees from the workplace e and spend the majority of time in their home. Thus, for the elderly, the residential space is a field of action and passageway connecting with the surroundings For the solution of physical space preparing the aging phenomenon, the combination of residential and medical function creates a new type of a lifestyle.

As serving people's activities, pedestrian road systems are basic and necessary facilities in urban structure. To provide and utilize these pedestrian road systems in residential area would enhance urban environment as well as quality of life. For this reason, pedestrian road should be planned by consideration of people's activity in residential area. Evaluation of existing pedestrian road should be also oriented how people use it and what people do in it. This study amis to investigate functions of pedestrian road system throughout evaluation of user's satisfaction in order to improve better pedestrian road system in residential area. The purposes of this study are to analyze components of factors affecting on user's satisfaction, and to find the relationship among affecting factors. For this study, the on-site questionnaire method was applied to 267 individuals who were collected as the study areas where locate Toyogaoka and Kaidori, Japan. The collected data were clarified exploratory factors, and analyzed relationship between the factors and satisfaction by applying quantitative statistical techniques for the mapping investigation, Mann-Whitney u-test, and correlation. The results of this study are follows. The pedestrian road system is more preferred than surroundings of vehicle roads in residential district area where maintains pedestrian road as open space. In addition, satisfactions of the pedestrian road for each purpose were highly evaluated, because of conformability and convenience for usage. Consequently, the pedestrian road which is secure and greening as an open space is well carried out for the living circulation of residents. It would suggest that pedestrian road have to be managed and planned not a function of circulation but an open space system.

Residential architecture was a lot more changed due to adopting modern residential type since 1960s. But people in farm houses are still living in a space of their past life causing a discrepancy. For this reason, the paper will identify the changed use for farm houses focusing on their plane views, and reason for the changed use as well. The result of this paper is expected to play a role for practical data to reasonably change and re-model farm houses located in back of cities such as Hyunpoong area. Targeted area for this paper, in order to survey change in residential environment due to industrialization and modernization, has narrowed down to 42 farm houses which are located Yuga-Myun, Hyunpoong-Gun, Dalsung-Gun where tradition and modern characteristics are harmonized being built before 1960s Researching relied on both documentary records and survey on the site, and survey on documentary records was performed in a way that preceding research for changed use of residential area was to be compared with people's farm houses in Kyeongsang-Do area, and survey on the site was carried out by photographing and land surveying and interview and analysis for them, and finally we acquired the result by analyzing use of interior for houses and plane view and relations between culture and social environment. From the result of this paper, there was a trend that farm houses had been improved function of a specific space by enlarging space and enlarged construction for inner rooms. And among spaces, kitchen and bath room was mostly enlarged its left side, and inner room had mostly enlarged its rear side, and kitchen was frequently enlarged in its side space. These kinds of variation in space is believed to be result of change of life style and house facilities

Water is an indispensable input to human's existence and industrial production. A water supply project would demand considerable costs, but produce economic benefits, which are importantly utilized in the project evaluation. In this situation, this study attempts to value the economic benefits from the residential water supply in Seoul. In particular, yearly consumer surplus and economic value of water supply for eleven water authority agencies in Seoul are measured during the period 2001-2004. Information on price elasticity required in calculating consumer surplus is obtained from direct estimation of the residential water demand function, and the consumer surplus is assessed by using a recently developed formula. Price elasticities used here are -0.810 and -1.011, and the estimated consumer surplus and economic value amount to 131.9 to 164.6 billion won and 398.6 to 431.3 billion won, respectively.

This research aims to investigate the alterations in typhoon patterns attributable to climate change and to quantitatively assess the risk of damage to residential structures. The increasing prevalence of climate anomalies and severe weather events, a consequence of global warming, is causing escalating damage globally. Notably, numerous countries are facing substantial devastation due to shifts in typhoon trajectories. Despite this, there exists a gap in empirical research quantifying the impact of these changes on building integrity and the associated risk alterations driven by climate change. In addressing this gap, our study analyzes the frequency and intensity of typhoons impacting Korea, examining the evolution of these meteorological phenomena. Furthermore, we employ the Korean Typhoon Vulnerability Function for residential facilities to quantify the altered risk posed by these changing patterns. The outcomes of this study provide the private sector with essential data to formulate diverse scenarios and business strategies in response to the escalating risks of typhoon-related damage. Additionally, it equips governmental bodies with the necessary insights to develop comprehensive risk management strategies to mitigate the effects of future typhoons.

Space plays a very important role in the human residential environment. Space is where the direct experience of life and expansion of that experience are made out of simple residential space. In particular, kitchen space is where the importance of the living space is perceived and is becoming an everyday part of life through television programs. Thereby, kitchen space is where the culture of everyday life plays a role in communication based on the very important production and function of television culture. The kitchen is where various experiences emerge. It is a space where the phenomena of communicating through cooking, experiencing tastes, and communicating with family members is realized. The purpose of this study is to analyze the relationship between communication and production in the kitchen through analysis of "Yune Restaurant 1" on tvN channel. The results of this study show that the human kitchen space leads to expansion of various experiences in the process of various cultural discounts.
