It shows 21st century as a networking society that is moving up the concept of global town and being industrialized with regional and personal connections. Individual's original idea and variety of 21th century may be respected by such environmental change, and age (Literary, human axis, technology axis, nature axis, kaining farming axis are central keyword) of culture that cultural capacity of individual becomes important fetters that create added value is forecasted to become. The moaning for space that is unemployment enemy by change of conceptional environment about cultural life and agreeable quality of life by development of Information-Communication technology may be required newly. As it does interaction along with development of science technique and Information-Communication technology, the future environment of various that complex! Is predicted to form network environment (existence space, cyberspace) newly. Human central interest is risen in technology balance hereupon, and these characteristic escaped in physical system that do with functional special quality and require human central and sensitive interaction. First, if examine about phenomenon by Digitize and chance aspect that is risen in 21th century, Digitize is time that action occurs fusion Tuesday that is various and Blur phenomenon of city·space, and the period to collapse the border between several individual. Second, importance more than man-centered and sensitive aspect of functional physical system is risen by digital age with development of technology medium, and as the five digital senses showed up, it suggests a sensual of the times and therefore the interest and direction get set up for the sensual sides of consumers. Third, special quality is, medium enemy by that digital space connotes meaning disk floret, variability, transparency, space red of extensity etc.. to burn and is digitalised, can be risen by symbolic, original individualities and emotional communication's the importance is required sensitivity enemy who is sympathy horn by fusion anger of individual. Technology of new media may open direction of new communication through interface that did not enjoy so far is going to supply new means that can express own to human

Newly constructed, high-rise dense building areas by urban development can cause changes in local wind fields. Wind fields were analyzed to assess the impact on the local meteorology due to the land use changes during the urban redevelopment called "Eunpyeong new town" in north-western Seoul using CFD_NIMR_SNU (Computational Fluid Dynamics, National Institute of Meteorological Research, Seoul National University) model. Initial value of wind speed and direction use analysis value of AWS (Automatic Weather Station) data during 5 years. In the case of the pre-construction with low rise built-up area, it was simulated that the spatial distribution of horizontal wind fields depends on the topography and wind direction of initial inflow. But, in the case of the post-construction with high rise built-up area, it was analyzed that the wind field was affected by high rise buildings as well as terrain. High-rise buildings can generate new circulations among buildings. In addition, small size vortexes were newly generated by terrain and high rise buildings after the construction. As high-rise buildings act as a barrier, we found that the horizontal wind flow was separated and wind speed was reduced behind the buildings. CFD_NIMR_SNU was able to analyze the impact of high-rise buildings during the urban development. With the support of high power computing, it will be more common to utilize sophisticated numerical analysis models such as CFD_NIMR_SNU in evaluating the impact of urban development on wind flow or channel.

In rural settlement planning, its spatial development framework should be constructed on the basis of the hierachial settlement system. However, up to now, there does not exist widely - accepted model on rural settlement hierachy. In this study the basic planning principles and directions on the modelling of the settlement hireachy in rural areas have been consolidated through theoretical study and situational analysis on planning environments. And also, a new yardstick on the grading of the middle - level centers between villages and rural towns has been tried to find out. The research resulted that the existance of periodical rural market might be used as a simple and innovative yardstick on the hierachial ordering of rural settlement system. Based on the above results, an alternative 4 - step model of rural settlement hierachy was proposed ; Rural Town(county hall sitted) -Market Center(having standard periodical market) - Village Center(having no market) - Village. Finally, because the conclusion has been made by very limited case studies and several previous works, there should need continuous studies and checks in future for full reasoning of the proposed model.

Comparison between photocatalysis and sonophotocatalysis were performed in lab-scale experiments for the treatment of benomyl. The effect of operational parameters, i.e., initial benomyl concentration, $TiO_2$ concentration, $H_2O_2$ concentration on the degradation rate of aqueous solution of benomyl has been examined. The optimal conditions for photocatalysis and sonophotocatalysis processes were determined: initial Benomyl concentration was 3 mg/L, the concentration of $TiO_2$ was 2 g/L and $H_2O_2$concentration was 1.5 mM. Under the optimal conditions, sonophotocatalysis was effective for inducing faster degradation of the benomyl.
