This study is examined river naturality and vegetative composition of river riparian zones to identify their most important sources of variation. Information on plant species cover and on physical characteristics that occur at upper, medium, and low areas was collected for 30 riparian plots located throughout the Youngjeong River in Korea. The riparian areas of river banks are dominated by mixed sediment and the vegetation is composed of herbs, shrub, and trees. The floristic characterization of riparian at this river during 2015 season was identified with a total of 28 families, 72 genera, 75 species, 13 varieties, 23 associations. The vegetations of low water's edge and flood way at upper region were naturally formed various vegetation communities by natural erosion. Forty plant species were identified around the upper region, where the dominant growth form was mostly trees. The flood way vegetation at middle region was both of natural vegetation and artificial vegetation. Land uses in riparian zones river levee at low region were bush or grassland as natural floodplain. The values of cover-abundance at upper, middle, and low region were total 9.26, 7.24, and 7.56, respectively. Grasses and forbs at the Youngjeong River have similar cover-abundance values. Recent, many riparian areas of this river have been lost or degraded for commercial and industrial developments. Thus, monitoring for biological diversity of plant species of this river is necessary for an adaptive management approach and the successful implementation of ecosystem management.

Semi-industrial zone is the area where manufacturing, residential, commercial zones are mixed. Despite of their potentials in that proximity to city and convenient transportation infrastructure, a lot of semi-industrial zones in Korea have converted to other uses due to many issues such as change of industry, increasing land price, real estate speculations. Recently, local government is trying to solve their existing issues and develop them through a restoration of publicness. Now publicness is thought of as a key factor of regeneration in semi-industrial areas. In this regard, this study aims to examine the way of restoring publicness revealed in Brooklyn Navy Yard mainly focus on their urban contexts and architectural ways. Brooklyn Navy Yard, an exemplary case, is an industrial complex that has grown economically, socially and culturally through emphasizing publicness and it is evaluated as an advanced example of public industrial complex. Through the analysis of Navy Yard, this study was trying to emphasize the importance of publicness in the regeneration of semi-industrial areas and to provide implications for the Seoul Government's solutions, which are still in the conceptual stage. To analyze the publicness of the study subjects, framework and elements were derived by examining related theories and prior researches. Depending on this frame, the results of the publicness of the Navy Yard were as follows. First of all, the 'Publicness as an officiality' was identified at the characteristic of the site and Navy Yard development corporation. Second, the 'Publicness as a public interest' of the Navy Yard Development Corporation was identified in various ways of its operation methods. Finally, the 'Publicness as an accessibility' was identified in the opening of urban and architectural spaces in Navy Yard. These publicness were analyzed with seven Navy Yard's success factors. Thus, it can be interpreted that the publicness of the semi-industrial areas can contribute significantly to their success. The publicness restoring methods of Navy Yard could be used as a basic data in semi-industrial areas in the future in Korea. However they are limited to be applied directly, so extensive and in-depth research in terms of their applicability should be conducted.
