Policy problems are complex due to diverse participants and their relations in the policy processes. Defining the right problem in the first place is important because Type III error is likely to happen without removing rival hypothesis in defining the problem. This study applies Boundary Analysis suggested by Dunn to structure IT policy problems in Korea. The time frame of the study focuses on 5 years of Lee Administration and data are collected from four newspapers. Using content analysis, the study, first, elaborates total 2,614 policy problems from 1,908 stakeholders. After removing duplicating problems, 369 problems from 323 stakeholders are identified as a boundary of IT policy problem. Among others, failures in government policies are weighted as the most serious problems in IT policy field. However, many significant problems raised by stakeholders dated back to more than a decade, and those are intrinsic problems, which initially caused by market distortions in the IT industry. Therefore, we should be cautious not to overemphasize the most conspicuous problem as the only problem in the policy field when we interpret results of problem structuring.

The slope revegetation methods in Korea are generally the hydroseeding mixed with perennial herbs, soil, fibers, and fertilizer in consideration of scenic landscape rather than ecological and engineering effect. But perennial herbs can't protect the slope from deep surface erosion and they are not tall enough to create the original naturalness at the boundary parts of existing woodlands. This study is about the slope revegetation method using nutritional propagation capacity of plants and the experimental construction was carried out on the cut-slope of Yongin Hoam C.C. We dug several trenches to a depth of 80cm and at intervals of 150cm from each other. After placing various kinds of live branches(Salix species) into the trench, we backfilled with the excavated soils and finally sprayed water mixed with soil-stabilizer, fertilizer. As six months passed, we made a vegetation research and check the slope surface erosion. Vegetation research was performed in examining the frequency of each block using transect method. 31 kinds of plant species appeared in total area($113.6m^2$) and the dominant species are Setaria viridis, Artemisia rubripes, Persicaria pubescens, Plantago asiatica, Cyperus amuricus, Commelina communis. Among the examined blocks, '아', the top part of the slope, showed the ratio of 1.4 as the highest Alpha-diversity. With regard to life form, therophytes were shown dominant distribution of 58% of total species and neophytes relatively low distribution of 16%. It can be estimated that there is no ecological stabilization of this slope, because of ruderal species' occupation of 74% in total area. Regarding the slope stabilization, the serious surface erosion didn't take place in spite of heavy rainfall this year, but a little surface erosion took place at the block where no other species coming from outside of the site were found.

This study is to analyse Korean map inserted in the "Gwandong Gwanseo-jido(關東 關西地圖)" which is reserved in the Gyujanggak Archives as the mother edition of Korean Map("朝鮮圖") in Kangxi Atlas made in Qing dynasty. Map in Gyujanggak is very similar to the Korean map in the Kangxi atlas in terms of shape of southern part of Korean peninsula, boundary of provinces. Especially over 80% of place names on two maps are coincident and over 90% of islands names are identical. It is revealed that map in the Gyujanggak Archive is the most similar map to the Kangxi Atlas in Korea. This map was produced in 1729~1736 which is late compared to the Kangxi Atlas. This difference of production period shows that mother editon of map in Gyujanggak is the base map of Korean Map in Kangxi atlas. The similarity and differences between those maps show the process of edition of geography in the produce the Kangxi atlas. And map in Gyujanggak shows that production of new type of Korean whole map was began in the late $17^{th}$ century.

Efficiency and universality which was the spirit of the modern age, had also an enfluence on our living environment. Various types of individual housing unit were developed and mass-produced. However, the exterior space in our city is a place for our social life and intermediate place to connect the private life of each individual to our society. For the people to adapt themselves well to their environment, it should be well organized which means it is clearly divided and integrated in a hierarchical order. To realize these conditions, adequate boundaries to divide each territory and entrances to connect each territory are two essential elements. One of the possible methods to realize these conditions can be found in korean traditional architecture where the exterior space has the same figural quality like buildings and is the center of the whole composition. Buildings, walls and colonnades are the elements to define space. Gates, pavilions, gabs between buildings and posts are the elements to symbolize the entrance connecting each space. Each exterior space is integrated to a whole composition. One is the gradual differentiation along the axis which is unique in korean traditional architecture. The other is the rectangular connection which is also found in the other area in the world. The results of this thesis are as follows. The exterior space in the housing area should have the figural quality. The elements to make boundaries defining exterior space are classified into horizontal elements such as low buildings and walls, and vertical elements such as tower-shape buildings which define space in a different way. The position of openings in a housing block affects the characteristic and openness of a exterior space. Various types of gates are used to decide the relationship between spaces.

This research aims to understand the precise character of relics based on literature search and material analysis of the jade excavated from the first buried place of King Jung-jo, and to assess the level of damage through non-destructive diagnosis. Furthermore, scientific conservation treatment was used to restore the original shape of the excavated jade. According to literature search, the excavated jade is known to be jasper, but material analysis showed that it was as a serpentine with the mineral composition of antigorite. Infrared thermography analysis to assess deterioration showed that the internal damage is the result of the interstices developed along the boundary surface of the obtained jade. For conservation treatment of the damaged area on the surface, the jade was filled with a mixture of plaster and glue, and covered with a mixture of acrylic paint and gloss medium for protection, and color was adjusted.

The objective of this study is to establish a methodology of bioregional approach for coastal area management as a basis for planning and design. Focusing on the bioregional approach, this study reviewed currently prevailing approaches such as watershed approach and ecological unit approach for planning and management purposes. This research placed its geographical focus on the landward watershed of the Bay of Hampyong located in Chonnam Province, dealing efficiently with shortcomings of existing researches which mainly covered seaward tidal flats without considering outside effects. The main methods of the study are classified into indoor computerized map analysis and field work. For computer analysis, printed maps and digital maps have been analysed, and GIS techniques have been utilized for its synthesis and finalizations. Field work included on-site landscape analysis and verification of a tentative place unit boundary. As a practical step, criteria for classifying bioregion were presented and the selected criteria included : topography & water ways ; roads & administrative boundaries ; habitat types ; and visual enclosure. First, based on the data of topography and water ways, broad classification work was performed and corrections were made based on data drawn out from other criteria. A tentative place unit map was drawn and revised through field visits. This study encompassed an initial but integral part for bioregional approach in landward watershed management of a coastal area. As results of the study, the necessity and efficiency of bioregional approach which considers environmental and cultural components systematically have been presented.

Recently, it is considered that the fashion flagship stores are being standardized as they are focusing only on external decorations and that they are hardly expressing their own intrinsic identities. That being the case, the fashion flagship stores are, now, pursuing diversity and are trying for any experimental designs in order to make their spaces more unique than those of other fashion flagship stores are, and regarding customers who would visit the stores, they have this desire to experience spaces, which are all unusual and different, just quickly while they shop. The topic of this study, depaysement which is making it unfamiliar, applies some unfamiliar a stimulus to people, and that makes the users remember this realization of original images and psychological stimuli as long as possible as leading the users to experience those spaces of special values. In the light of that, this study categorizes the features of depaysement into those groups, such as distortion of scales, juxtaposition of foreign materials, fantasy and ambiguity of a boundary, and analyzes the interior spaces of the fashion flagship stores. After all, this study applies depaysement to the fashion flagship stores' interior spaces, which have been all familiarized and standardized through some habitual relations, and works on different stimuli in order to invite the users to experiences of those totally new senses which are different from what the users have been felt in their daily lives. In the end, the study aims to propose ideas for how to design a place attractive enough to make the users revisit the place as after going through such memory process mentioned on the above.

Progressive collapse in a structure occurs when load bearing members are failed and the adjoining structural elements cannot resist the redistributed forces and fails subsequently, that leads to complete collapse of structure. Recently, construction using precast concrete technology is adopted increasingly because it offers many advantages like faster construction, less requirement of skilled labours at site, reduced formwork and scaffolding, massive production with reduced amount of construction waste, better quality and better surface finishing as compared to conventional reinforced concrete construction. Connections are the critical elements for any precast structure, because in past, major collapse of precast structure took place because of connection failure. In this study, behavior of four different precast wet connections with U shaped reinforcement bars provided at different locations is evaluated. Reduced 1/3^rd scale precast beam column assemblies having two span beam and three columns with removed middle column are constructed and examined by performing experiments. The response of precast connections is compared with monolithic connection, under column removal scenario. The connection region of test specimens are filled by cast-in-place micro concrete with and without polypropylene fibers. Performance of specimen is evaluated on the basis of ultimate load carrying capacity, maximum deflection at the location of removed middle column, crack formation and failure propagation. Further, Finite element (FE) analysis is carried out for validation of experimental studies and understanding the performance of structural components. Monolithic and precast beam column assemblies are modeled using non-linear Finite Element (FE) analysis based software ABAQUS. Actual experimental conditions are simulated using appropriate boundary and loading conditions. Finite Element simulation results in terms of load versus deflection are compared with that of experimental study. The nonlinear FE analysis results shows good agreement with experimental results.

The national boundary's meanings turn to weak according to advent of Global enterprises. The place for design a product and marketing are separated to actual market. R&D is to the area where the knowledge activity is well, and low skilful product assembling is to the place the low wage is acceptable. It shows that the importance of net work structure. From early 90's, production system is diversified to markets where with the consumer as the central as multifarious items and creation new demands through consumer's participation into manufacturing process. This phenomenon show that logistics structures adapt to demand of technical variation, and the development of e-business with VAN(:value added network) and EDI(:Electronic data interchange) prove it. This study tried to analyze utilitarian assay about systems those land, sea, air logistics through documents research, and this study also present the direction of logistics system of airline company and goal of development on the based to the model of domestic airline company accordingly.

Korean-Japanese architect Itami Jun that proceeded with primeval architecture based on analogue ideas in the digital era realizing nomad architecture is delivering a totally different meaning in the modern time. Not like the Japanese architectural community equipped with rich technologies showed state-of-the-art architecture after 1980s, Itami Jun' formative consciousness intending to assimilate nature from the original position of things is thought to have started from the relationship with Korean-Japanese painters leading MONO-HA desiring to look at the world as it is and approach the source of existence. The purpose of this study is to analyze the spatial characteristics from the viewpoint of 'Theory of Meeting' which is the essence of the work theory of Lee UFan that made the theoretical foundation of MONO-HA to understand Itami Jun's architectural space in the ideological aspect. Although the characteristics of marginal men appearing in Itami Jun's architectural space as others located on the boundary between Korea and Japan, art and architecture, and functions are valuable research objects, they have not been studied in the aspect of source, so it is needed to research his works and the source of the spatial ideas that led his works. Based on Theory of Meeting claiming that the world becomes the place of experience by the medium of objet which is the structure of meeting, and that human beings can meet the truly opened world by self-awareness through body, the expressive characteristics of Itami Jun's interior space was analyzed. As a result of the analysis, it turned out that Itami Jun's interior space actively expressed Theory of Meeting on the unity of structure and space, and on the trans-boundary by the medium of objet. Conclusively, this study suggests that, in the reality of the modern interior design full of technology-intensive designs, analogue approach moving in the opposite way from technologies could be a better expressive method of design delivering the fundamental human emotions.
