This study aims for proposing improvement method for streetscape in a small and medium city of Korea. According to this purpose, in chapter 2, by inspecting conservation of street environment and streetscape, deduce the frame for analyzing streetscape in commercial district. In chapter 3, analyzing present condition and problems of selected streets in Pohang City, derive the primary factors to induce desirable streetscape through problems and their reason between the analyzed elements of building form. Analyzed elements are composed of floor elements, wall elements, ceiling elements. The detailed elements are pavement of road, street furniture, height of buildings, color and material of building and outdoor advertisements. In chapter 4, by conducting a questionnaire survey of pedestrians about street images -choosing impressive physical elements and the feeling of the street by the list of adjective of semantic differential scale- and the preference, propose the direction of improvement about streetscape in commercial district.

We report the preparation and characterization of inkjet-based basicfibroblast growth factor (bFGF)-containing nanofilms on aflexible PET substrate. bFGF and heparin (HEP) were assembled by inkjet-basedlayer-by-layer (LbL) assembly driven by electrostatic interactions. The bFGF/HEP nano-assembly surfacecoatings were formed via alternating printing adsorption of positively charged bFGF and negativelycharged HEP; the process was monitored by UV–vis spectroscopy and quartz crystal microbalance. ThebFGF release profile could be controlled by altering the number of layers of printed LbLfilms. Mesenchymal stem cells, which are capable of extended proliferation in vitro, require a continuous supplyof bFGF for proliferation. However, enhancing mesenchymal stem cell proliferation by continuoussupplying bFGF is difficult, even with medium replacement, because of the instability of bFGF. Here, weestablished a novel system for releasing bioactive bFGF from a modified surface by using an inkjet-basednanofilm fabrication method.
