This study aims to track pedestrian behavior in urban linear tourist sites and to analyse their behavioral characteristics. For these purposes, this study has adopted the direct observation, a behavioral tracking methodology, and selected Chenggyecheon in Seoul as the study site, a representative site of urban regeneration. The main results of this study can be summarized as follows: the period of stay and movement distance of pedestrians in the study area are both short and most pedestrian activities, apart from walking, are of a passive nature, such as pitching pennies, reading signs, resting and the like. Spatial points of Chenggyecheon at which pedestrians have exhibited these behaviors during their stay are summarized as 30 points and classified into 3 types: landmarks, bridges and nodes. Further research that combines several tracking methods in terms of urban pedestrian behavior is needed.

The purpose of this study is to understand the relationship between physical characteristics and general people's perception. In this study, the physical quantities of artificial lighting were measured from the visual point of the pedestrian and general public perception including preference and satisfaction was examined. As a result of this study, the total luminance and mean luminance had different value in each site. However, there were no significant differences in area and number of light source between sites. The effects of these factors are affected by indoor lighting. In the group of respondents, 10s people, male, students, meeting, 1~2 times a month and 18:00~20:00 had higher satisfaction compared to other groups respectively. A total luminance and mean luminance gave effect on the satisfaction of physical quantities of artificial lighting and the satisfaction on night landscape. With increase in total luminance and mean luminance, the satisfaction was lowered. It is necessary to reflect these factors on the future policies of nightscape.

This study aims to examine the presence of non-stationary relationship between water quality and land use in watersheds. In investigating the relationships between land use and water quality, most previous studies adopted OLS method which is assumed stationarity. However, this approach is difficult to capture the local variation of the relationships. We used 146 sampling data and land cover data of Korean Ministry of Environment to build conventional regressions and GWR models for BOD, TN and TP. Regression model and GWR models of BOD, TN, TP were compared with $R^2$, AICc and Moran's I. The results of comparisons and descriptive statistics of GWR models strongly indicated the presence of Non-Stationarity between water quality and land use.

This experiment was conducted in order to study the physiological characteristics of Sedum takevimense in different moisture conditions. The photosynthetic rate, water use efficiency and the respiratory rate were determined by using a photable photosynthesis system. According to the results, the best illumination range and moisture range were explicitly selected. The highest photosynthetic rate was at $600{\mu}mol{\cdot}m^{-2}{\cdot}s^{-1}$, and after this value, the trend showed a reduction. When the moisture was 11.31%, the photosynthetic capacity and water use efficiency reached maximum value, but the respiratory rate reached maximum value at 7.91%. According to the measured values, the best illumination range was $600{\sim}1,200{\mu}mol{\cdot}m^{-2}{\cdot}s^{-1}$ and the best moisture range was 7.09~11.31%.

This study aims to examine various discourses of the urban landscape discussed in the fields of new cultural geography, spatial political economy, and landscape architecture in order to propose a theoretical framework for the interpretation of a contemporary urban landscape. The notion of landscape is a modern idea that separates humans, especially the bourgeois subject, from nature, and then achieves the visual possession of nature. New cultural geographers have studied the political aspects of landscape. According to them, landscape as materialized discourse is "a way of seeing" which includes the vision of the upper class, the imperialistic view, and the masculine and voyeuristic gaze. In addition, spatial political economists have paid attention to the economic aspects of landscape. They have emphasized that the material production of landscape is indispensable in the production of surplus values in the capitalistic system. Thus, we insist focusing dialectically on both the materiality and ideology of landscape.

The purpose of this study was to quantitatively examine the physiological and psychological effects of a waterscape facility in an interior landscape space. Data were collected as participants under stress relaxed in either an interior space with greenery(Type G) or an interior space with a waterscape facility(Type W). The participants relaxing in the Type W space showed significantly decreased systolic and diastolic blood pressures, and an impression evaluation by the SD method indicated that their impressions were expressed in more positive terms, such as 'vigor', 'dynamism', 'pleasantness', and 'vitality'; when compared to participants relaxing in the Type G space. A POMS analysis showed waterscape elements influenced participants' psychological mood states by decreasing tension and fatigue, but increasing vitality. Introduction of waterscape facilities into interior landscape spaces could therefore provide stressed individuals with health benefits, including decreased blood pressure and positively changed psychological mood states.

The garden has long served as away of thinking about nature and about culture and how each influences the other (Francis and Hester, 1990). This study, viewing the garden as a representation of the ideal, tried to seek for detailed aspects of the aforementioned ideal with the representative examples of Thomas Jefferson's gardens. Hidden behind his best known position as a politician was his other career: designer and creator of several gardens. Monticello, Academical Village, and Poplar Forest represented not only his ideals of national values like freedom, democracy and agrarian society, but also a yearning for the rural area and ideals for higher education realization. His personal desire and ideal are represented inside the spatial order, together with his ideals as a politician and the pioneer of new country. By representing the symbolic meaning metaphorically and restructuring it through a spatial scheme, Jefferson's ideal was admired and shared with visitors. In this way, Jefferson's gardens were practical stages to reveal his ideals.

This study was accomplished by analyzing the change of land cover pattern in high-rise buildings in Korea. For this study, we selected 15 locations of high-rise buildings. The ratio of average building coverage and paved area was 79.7%, and both green and water area were low, relatively. The biotope area factor of the site showed low percentage by 15.90% due to the underground space development. As a result of correlation analysis between the time of construction and land-cover type, building coverage has been decreased according to the stream of time. However, biotope area factor has been increased And, the paved area has m correlation. It was identified that reducing paved area is effective to enhance the ecological functions of a high-rise building outdoor.

In Seoul, skyscrapers are built in commercial zones known as residential-commercial complexes, which cause such environmental problems as urban heat islands(UHI) and air pollution. To investigate air temperature differences in areas near skyscrapers at Gangnam-gu, Seoul, South Korea, fixed air temperature observation and traverse observations were performed from March 16, 2008 to March 15, 2009. The annual mean air temperature at Tower Palace(TPL) was higher than that at Sookmyung Girls' High School(SMG) by $0.7^{\circ}C$, although the distance between the two observation positions is only 200m. The number of tropical nights at TPL was 13, while that at SMG was 5. The higher air temperature at TPL was due to a significantly lower sky view factor(SVF), which prevented long-wave radiation from emitting into the sky. The highest air temperature increases near TPL occurred on summer nights because of the high-electricity consumption value of $70.22Wh/m^2$ for the TPL block in August due to air conditioning for cooling. It is concluded that the warm air pocket centered on TPL.
