The purpose of this paper is to analyze the residential location preference factors by households' characteristics in the case of Seoul metropolitan area households. The main results of this study are as follows. Firstly, residential location factors most preferred by Seoul metropolitan area households are accessibility of public transportation, followed by security and living environment. Therefore, we can see Seoul metropolitan area households prefer amenity and quality of life as residential location factors. Secondly, according to the results of AHP by age and household income, the residential location factors Seoul metropolitan area households prefer are different by age and household income. Thirdly, according to the results of comparative analysis between the case of Seoul metropolitan area and Daegu Gyeongbuk households, Seoul metropolitan area households more prefer safety and quality of life, on the other hand, Daegu Gyeongbuk households more prefer investment value of housing.

The Ministry of Environment established a guide line Indoor Air Quality Management guidelines in Public Facilities in December 2006. As the items of the guideline, $CO_2$ (Carbon dioxide) and PM10 (Particulate matter). Therefore trains and subway need to control air quality. The indoor thermal environment in passenger car is very important for the enhancement of the amenity and health of passengers. Many researchers have studied it not for train but for building. So, in this study, we have performed thermal environment in passenger car (KTX, Mugunghwa, Saemaeul), and verified the relation between the PMV (Predicted Mean Vote) and PPD (Predicted Percent Dissatisfied) from September to October 2007. As a result, the average PMV value for each trains are 0.1, 0.22 for KTX, 0 for Mugunghwa, 0.1 for Saemaeul. So it satisfies the ASHRAE Handbook thermal environmental limit (-0.5 < PMV < +0.5).

The color and structure of urban constructions is a factor of urban landscape and shows their characteristics. Hence the modern buildings with their materials and external appearance makes up the urban image. But still yet, it was not easy to evaluate the value of visual landscape of buildings with objective measuring method. Most of all, it depends on the subjective estimation of a few talented or high educated experts with a sense of beauty. In relation to this kind of problems, it was tried here in this study to analyse the human response of brain wave pattern (EEG) with use of SD method, while the tested persons watched the urban landscape constructed in a visual reality. The tested persons were 10 adult males and females with no color blindness and intact cognitive function. Light source with color filter was used for color environment in chamber room. The signal of EEG is analysed digitally and grouped into the $\alpha$ and $\beta$ waves. The result showed that relative power of $\alpha$ wave ratio increased in natural landscape scenary clearly. From these results it was possible to evaluate the human response, which was affected by urban color and structure stimulation and it might be useful as an indicator of visual cognition amenity toward the design of urban construction environment.

The study aims to identify the design character of libraries today into outwardness which enhances publicity in the library buildings. This design trend tends to be emphasized in contemporary civic libraries. In these days, the libraries become not only to be the traditional places of information but also to be the multi-purpose places to provide community services and cultural spaces. Thus the contemporary libraries, especially big civic libraries, are willing to open to the public of diverse purposes and to accelerate social communication among them through outward design in the buildings. This study surveys literatures and identify accessibility, symbolism, openness, amenity, connection, as the characters of publicity in the libraries. The study also examines the outward design strategies of the libraries which enhance publicity in the ways of design to connect surrounding environment, to symbolize buildings, to wrap transparent external surfaces and to build interior spaces. The study finds in the case studies of ten outstanding civic libraries abroad which were built in relatively recent years that the outward design is achieved mainly through four ways. First, the libraries have connection with surrounding urban environment, thus have continuities from the surrounding. Second, the libraries have the shapes of landmarks which expose themselves and their roles to the outside. Third, the libraries have transparent surfaces through which outdoor environment penetrates into the buildings. Fourth, the libraries have corridors and halls which look like traditional urban public streets and plazas. The study concludes that outward design strategies which employ in contemporary libraries enhance publicity in the libraries. Thus the libraries can perform as multi-functional cultural and open places which accelerate social interactions among the public of cities. This study has the value as a research which emphasizes outwardness as the design strategies which enhance publicity in contemporary libraries.

There are many agricultural facilities (46.7%) that have been over 30 years in the Republic of Korea (the ratio of reservoirs built before 1945 is 53%, from 1946 to 1971 is 35%). In the case of reservoirs which do most important functions among these facilities, only 3,000 reservoirs are managed by Korea Rural Community & Agriculture Corporation (KRC) and the other 15,000 reservoirs are managed by local authorities (City and Gun). But, 15,000 reservoirs included in City. Gun have been built in more wide area than KRC and the reservoir management system has not been operated well because of shortage of budget and manpower of the local authorities. Particularly, the abnormal weather happened during every summer season recently has ruined a lot of rural community facilities. So flood control function have been more important than irrigation function in agricultural reservoir system and it may be required to introduce new safe, management and maintenance techniques in City Gun reservoirs. So we investigated landscapes and deteriorations of agricultural reservoirs managed by local small governments for revealing not only present usage but also future value. Survey shows that there are no structural managements except typical hydrological reportings and the deterioration of small darn is very serious. There are needs for more systematic management system and equipment methods. Therefore, this study may suggest that reservoir (that takes charge of the greatest deal of weight in all agricultural facilities) must be considered as new concept of the usage and the unification. On the other hand, reservoir must be also developed as amenity resources, natural circumstances and district values.

This study aims to identify and reduce the gaps of understandings and thoughts of river restoration between river engineers and ecologists by logically re-examining the definition and value of river restoration. For this purpose, function, and goods and services of river ecosystem are analyzed based on the study of those by de Groot et al. (2002). From the result of this analysis, definitions and strategies of presently-known river restoration and its similar activities are re-examined. Next, presently-known river restoration models, ERM (Ecological restoration model), ARM (Amenity restoration model) and semi-ERM (semi-Ecological restoration model), are reinforced in their frameworks. This study is expected to narrow the gap, between the professionals of different fields, of their understandings and thoughts of river restoration.

Odor problem of livestock operation is important issue in a local community. I quantified the property price impact of 199 livestock operations for 3,355 housing sales in the U.S (Colorado). Spatial hedonic model was adopted to deal with spatial autocorrelation in housing market. Small beef and dairy operations, which are the traditional agricultural sector, seem to create a positive rural lifestyle amenity effect. However, the impact of livestock operation on rural residential sales turns to negative if the operation is over a certain size and species. Large hog and sheep operation seems to bring fatal economic loss from the local community perspective if it close to residential area. Livestock odor is one of the negative externality, the results provide the potential social cost of the livestock sector in the region. Policy makers may incorporate this social cost in the regional planning to minimize the social and maximize the development effect. Therefore, local officials and private individuals should carefully consider the location and characteristics of new residential properties and livestock operations alike.

Rural areas dominates the country landscapes in size with less population and rich traditional heritages as well as natural landscapes. Rural community groves (RCG) and Dangsan groves have been established by community residents during a few hundred years, and most of them have been disturbed. Only a few RCGs and Dangsan groves remain for an extensive period with efforts from community residents. These remnant RCGs and Dangsan groves are highly evaluated representing Korean rural cultural landscapes. Sound understanding on the structure of the rural landscapes and their role on the rural community environment is required to provide an appropriate policy for managing rural landscapes. This study aims to understand the characteristics of RCGs and Dangsan groves in the cultural landscapes, to investigate policies and issues of the advanced countries on RCGs and Dangsan groves, and to overview domestic policies for rural landscapes. The study results showed that there is a close relationship between RCGs and main issues discussed in EU countries. Ministry of Agriculture & Forestry of Korea, Ministry of Environment and Rural Development Administration have to focus on the potential of RCGs and Dangsan groves for multi-functions of agricultural and rural areas, natural streams, rural amenity, direct subsidy for landscape preservation and rural tourism. Based on the findings, this study suggests that RCGs and Dangsan groves will provide benefits to develop rural-mountain-sea villages and to enhance country's landscapes as well as local landscapes.

The color and structure of urban constructions is a factor of urban landscape and shows their characteristics. Hence the modern buildings deal with their materials and external appearance as an important factor, making up the urban image. But it was nearby impossible to evaluate the value of visual landscape with objective measuring method. Most of all, it depends on the subjective estimation of a few talented or high educated experts with a sense of beauty. Such kinds of estimation can in some cases include arbitrary interpretations. In relation to this kind of problems, it is tried here in this study to analyse the human response of brain wave pattern (EEG) with use of SD method, while the tested persons watch the urban landscape scenery constructed in a visual reality. The tested persons were 20 adult male and female with no color blindness and intact cognitive function. Light source with color filter was used for color environment in a dark soundproof chamber. The signal of EEG is analysed digitally and grouped into the ${\alpha}$ and ${\beta}$ waves. The result showed that relative power of ${\alpha}$ wave ratio increased in the natural landscape scenery with blue and green color. From these results it was possible to evaluate the human response, which is affected by urban and natural color and structure stimulation and it might be useful as an indicator of visual cognition amenity toward the design of urban construction environment.

Green roofs can reduce surface water runoff, provide a habitat for wildlife moderate the urban heat island effect, improve building insulation and energy efficiency, improve the air quality, create aesthetic and amenity value, and preserve the roof's waterproofing. Green roofs are mainly divided into three types : intensive, simple-intensive, and extensive. Especially, extensive roof environment is a harsh one for plant growth; limited water availability, wide temperature fluctuations, high exposure to wind and solar radiation create highly stressed environment. This study, aimed at extensive green roof, was carried out on the rooftop of the library at Seoul Women's Univ. from October to November, 2012 and from March to August, 2013. To suggest the most effective vegetation model for biodiversity and heat island mitigation, surface temperatures were monitored by each vegetation model. We found that herbaceous plants of Aster sphathulifolius, Aceriphyllum rossii and Belamcanda chinensis, shrub of Syringa patula 'Miss Kim', Thymus quinquecostatus var. japonica, Sedum species can mixing each other. Among them, the vegetation models including Sedum takesimense, Aster sphathulifolius, Thymus quinquecostatus var. japonica was more effective on the surface temperature mitigation, because the species have the tolerance and high ratio of covering, and also in water. Especially, in the treatment of bark mulching, they helped to increase the temperature of vegetation models. In the case of summer, temperature mitigation of vegetation models were no significant difference among vegetation types. Compared to surface temperature of June, July and August were apparent impact of temperature mitigation, it shows that temperature mitigation are strongly influenced by substrate water content.
