Empathy is the ability to feel, understand, and respond to the emotions of others from the standpoint of others. Recently, 'sympathy' has emerged as an important issue not only in emotional empathy in relation to individuals but also in 'social empathy', which sees sympathy as a basic principle for maintaining society. This study focuses on the issue of empathy as a new driving force for modern society and focused on 'urban scene' as a spatial application for cultural empathy in the city. Urban scenes approach the city as a space of consumption, classify it according to its inherent attributes, and analyze its characteristics. This study approaches the existing urban scene theory in terms of empathy. In addition, as a way to consume city images reflected on contents, a concrete example of 'contents tourism'is examined, and a 'contents scene' is proposed as a new urban scene and its meaning and possibility are presented.

Recently, Interest in the riding of bicycles increased, but existing researches on the effect of bicycle facilities and the supply analysis and evaluation bike analysis of the importance of the item is most fulfilling. Those do not reflect characteristics of the region and the current satisfaction on the riding of bicycles. Therefore, this research will classify Gu Dong of Busan into good region, possible region and difficult region on the riding of bicycles to reflect characteristics of bicycles with the non-power and characteristics of riders with the main purpose of the exercise. Maintenance of bicycles classified according to the region will be decided to the Line-to-Line maintenance as to connect the main point of regions and to the Point-to-Point as to link the main point within region. Then, step-by-step bicycles activation of Busan differentiated by region offers. Also, Survey on Gangseo-Gu, Sasang-Gu, Gijang-Gun with good bicycle conditions and Busan-Jin-Gu with the best maintenance effect will be about the bicycle. The structure model of consciousness-based on the use of bicycles will be made by using Survey results and considering the region characteristics. This structure model will show a correlation of the current satisfaction, the bicycle-related facilities maintenance policy needs, region characteristics and the next intends to riding the bicycle.

Five representative reference evapotranspiration(RET) equations were selected, and these equations were compared with pan evaporation by correlation analysis. Pan coefficients were also estimated. Furthermore, five selected RET equations were compared to find the similarity among those at the 21 meteorological stations located in South Korea. Five RET equations selected from 4 different category were Penman(combination approach), FAO Penman-Monteith(FAO P-M) (single source approach), Makkink and Priestley-Taylor (radiation approach) and Hargreaves(temperature approach) equations. In this study, the geographical and topographical conditions were considered for the selection of study stations. The daily meteorological data measured from 1970 at an interval of 5 years were applied in this study. The evapotranspiration estimates obtained by applying evapotranspiration equations were evaluated with numerical and graphical methods. The correlation coefficients between pan evaporation and RET in study stations were above 0.9 indicating very high correlation; however, the slopes of the individual regression lines show the values greater or less than 1.0. Hargreaves equation(temperature approach) shows the most similar evapotranspiration estimates to those of FAO P-M equation from 12 study stations, which are located near to seashore except Daegu station. On the other hand, Priestley-Taylor equation(radiation approach) shows the most similar evapotranspiration estimates to those of FAO P-M equation from 8 study stations, which are located in inland.

Local government takes an active role in the (re)making of local socio-economic space. To support such an argument, the three different actions by the local government of Taegu, urban planning and local industrial districts, the establishment of special educational institutions, and textile festival are analyzed. The division of the city's space into residential, commercial, and industrial area by local government constrained the location of local manufacturing industries. It also forced textile industry to move to the outskirts of Taegu. As the education level in South Korea rose after the late 1970s, the local government of Taegu as well as local industrial capitalists had to do something to acquire a stable supply of labor to local manufacturing industries, particularly textile one. After the late 1970s, the special classes for the education of local workers, especially textile ones were established within vocational high school and company-operated high schools were also built in Taegu. Finally, local government started a program of textile festival in 1985. Through textile festival, local government as well as local textile business people tried to reproduce textile industry as the main economic activity of Taegu.
