This study started with drawing problems of early implementation and suggesting improvement plans in order to lead a rural convergence industrialization district system to early settlement and management for its policy goals. The study aimed at 13 districts that were designated from 2014 to 2016 for analyzing an actual condition of promoting early implementation, and went ahead with it combining literature research, interview survey and specialist opinion investigation. The study examined and organized an outline, policy goal, and actual condition of rural convergence industrialization district. Furthermore, it analyzed an actual condition of promoting at each stage such as designating processes of rural convergence industrialization districts, operating body and system, regulation improvement, district supporting projects and relating projects, drew problems and finally suggested improvement plans. This study could be meaningful because it is the first study to grasp an actual condition of promoting early implementation and to remedy problems in order to manage rural convergence industrialization district system which was newly promoted since 2014 for its policy goal. In addition, it suggests that the further study of the result after managing district system for a certain period of time should be needed.

Land-use changes have made considerable impacts on humans and nature such as biodiversity and ecosystem services. It is recognized as important elements for land use planning and regional natural resources conservation to identify the major causes of land use changes and to predict a process of changes and effects. This study, by using a spatially explicit Dyna-CLUE model, analyzed correlations between driving factors, quantified location characteristics of different land use types using logistic regression analysis and examined future land use changes and its effects in Yangpyeong and Yeoju region. We expected land use changes based on the three scenarios with different future land demands and simulated future changes for spatial variations of land use for the 20 years. The outcomes shows that larger change was found in agricultural areas than forest areas, based on the change in built-up areas. The changes in forest areas, which were mainly occurred in edge area, were expected to affect a large impact on its ecotone. It was found to be the importance of the management of forest edge and the necessity of the environmentally sound and sustainable development in order to conserve natural resources of the region.

Inhabitants make a specific cultural landscape in various ways according to his culture. In this paper, I consider the characteristics of cultural landscapes distributed in Sangju. I divide Sangju-City Area owing to physical criteria(relief and drainage basin}, appreciate them according to human criteria(administrative district of Joseon Period, dialects, periodical market area} and classify into 6 small regions: (1) Nakyang Region is the traditionally central place based on alluvial plain marginal to Byeongseong stream and Dong stream, and on hills of Sabeol. (2) Nakdong Region is the traffic center which the water transport of Nakdong river and the land transport of Yeongnamdaero cross each other. (3) The upstream region of Byungseong stream is the agricultural region connected with Nakyang Region. (4) Jungmo Region is a intermontane basin where grape cultivation using its specific climate flourish. (5) Wharyeong Region is a mountainous sightseeing district based on the beautiful scenery and Gyeonwhueon's remains of Sogni mountains and Yongyu valley. (6) Hamnyeong Region is the district of Goryeonggaya realm where 3 whites(cocoon, dried persimmon, rice) are abundant.

This study reviewed different results according to the selection of viewpoints and considerations of the neighborhood in the analysis of view to regulate the height of buildings. To do this, 4 cases were set according to the analytical methodology and a GIS simulation was performed. Characteristics of each methodology were compared and analyzed by simulated values with ANOVA(analysis of variance) and post-hoc analysis. First, the method using moving viewpoints was found to be appropriate for the regulation of building height as it could reflect basic characteristics of landscape which was sequential and it did not show big difference in analysis result according to situational setting. Second, the method using grid viewpoints showed a problem that viewpoints at left and right sides viewed ridges of other mountains than the background mountains of the target land. Additionally, the simulation method that induces three-dimensional cross-sections between multiple sight-surface and virtual construction points created at viewpoints used in this study was found to be useful in the simulation review with various settings as it induced the marginal height of the spot quantitatively.

The discussion of this paper is concerned with the epistemology of urbanism and rurality, that is, the justification of certain knowledge claims about how to intervene in understanding of urban and rural way of life and their implications to space. It is not concerned with the search for "truth" as such, but rather with the construction and presentation of knowledge as truth that subsequently lead to interpretation in the form of scholarly arguments. Rural areas vary considerably, and we define it as of a socially constructed category and so does urban as a comparative construction. As with community, rurality has been defined in widely different ways so has urbanism. In identifying and interconnecting these two concepts, we incorporate diverse western epistemologies such as empiricism and pragmatism. In addition, we heed particular attention to the intellectual history of Silhak, a philosophical ideology of Korea, to identify the relationships and it's effect on social way of life encompassing the realm of rural and urban spaces. We found that Silhak is particularly useful in that it deals with substantive issues of the relationship between rurality and urbanism arising from the discordance between values and perceive conditions of the rural and urban way of lives. This paper argues that the epistemology of Silhak is particularly superior to those of western ideologies since it accentuates unity of spaces rather than differentiating urban and rural way of life. We concludes with demanding more studies in the field of urban and rural analyses incorporating more diverse concepts of Korean orthodox epistemology.

This study was conducted to refine a micropropagation method of water hyacinth (Eichhornia crassipes) in vitro. When young shoots were cultured on media with various concentrations of BA or TDZ alone, LS medium containing $5.0\;mgl^{-1}$ BA was found favorable for shoot proliferation from young shoots with a mean of 4.2 shoots. Using BA together with IAA, more shoots were obtained on LS medium containing $5.0\;mgl^{-1}$ BA and $1.0\;mgl^{-1}$ IAA with a mean of 5.7 shoots. In liquid medium, number of shoots and fresh weight per explant increased significantly. The best shoot proliferation and increasing of fresh weight were achieved on LS liquid medium containing $5.0\;mgl^{-1}$ BA and $1.0\;mgl^{-1}$ IAA with 6.9 shoots and more than 4,000 mg fresh weight. Of the different concentrations of LS salt, double strength of LS medium provided the highest shoot proliferation with 7.3 shoots, and fresh weight with 5,539 mg per explant. Shoot proliferation on LS medium containing $50\;gl^{-1}$ sucrose had better results with 8.7 shoots and 5,979 mg per explant in fresh weight than other conditions. In conclusion, the optimal level for shoot proliferation and biomass increase of water hyacinth was attained with the application of the double strength of LS medium containing $5.0\;mgl^{-1}$ BA, $1.0\;mgl^{-1}$ IAA and $50\;gl^{-1}$ sucrose.

As a study for the verification of heat treated wood according to ISPM No. 15, the spectroscopic characteristics of the heat treated wood surface were analyzed. Various functional groups were observed on the IR spectrum, but it was difficult to find any particular difference between wood species, heat treatment time and storage period. HBI (hydrogen-bonding intensity) shows the change of the heat treated wood according to the storage time, but the change of wood with the heat treatment time was hard to be observed. On the PCA score plot, however, it was possible to sort the wood according to the heat treatment time of 60 minutes or 90 minutes in the species. The standards for classification of heat-treated wood in PCA were aromatic rings in lignin and C-H bending in cellulose, and these components were able to classify heat-treated wood by ISPM No. 15.

The purpose of this study is to develop means to apply GIS and remote sensing technology to the analysis of Korean urban open spaces. To achieve this objective, a framework of analysis of urban open spaces was developed, and then the framework was applied for the evaluation of the potential and suitability of open spaces of Ansan City, which is a new town developed to accomodate industries relocation from Seoul, Korea, mainly due to their pollution problems. The software used in this study are IDRISI, a grid-based GIS, and KMIPS, a remote sensing analysis system. Both packages are based on IBM PC/AT computers with Microsoft DOS. Landsat MSS and TM data were used for the land use classification, land use change detection, and analysis of transformed vegetation indices. The size of the geographic data base is 110 rows and 150 columns with the spatial resolution of 100m$\times$100m. The framework of analysis includes both quanititative and qualitative analysis of open spaces. The quantitative analysis includes size and distribution of open spaces, urban develpment of open spaces, and the degree of vegree of vegetation removal of the study area. The qualitative analysis includes evaluative criteria for primary productivity of land, park use potential, major visual resources, and urban environmental control. The findings of this study can be summarized as follows. First, the size of builtup areas increased 18.73km$^2$, while the size of forest land decreased 10.86km$^2$ during last ten years. Agricultural lands maintained its size, but shifted toward outside of the city into forest. Second, the potential of open spaces for park use is limited mainly due to their lack of accessibility and connectivity among open spaces, in spite of ample acreage and good site conditions. Third, major landscape elements and historic sites should be connected to the open space system of the city by new accesses and buffers.
