  • In this study, we tried to utilize results of the change detection analysis for satellite images as the basis for updating the land cover map. The Sequential Spectral Change Vector Analysis ($S^2CVA$) was applied to multi-temporal multispectral satellite imagery in order to extract changed areas, efficiently. Especially, we minimized the false alarm rate of unsupervised change detection due to the seasonal variation using the direction information in $S^2CVA$. The binary image, which is the result of unsupervised change detection, was integrated with the existing land cover map using the zonal statistics. And then, object-based analysis was performed to determine the changed area. In the experiment using PlanetScope data and the land cover map of the Ministry of Environment, the change areas within the existing land cover map could be detected efficiently.

  • This study aim to do observation to 1) Trajectory of cognitive-cultural economy growth with regional historical context, 2) Spatial, cultural and social change caused by cognitive-culture economy growth, and 3) Draw the meaning of the change in glocalizational view. They said that 'Creativity' has been related with spatial, economical, cultural and social change and it leads to new economical system, what we call 'Cognitive-cultural economy'. It is the important event which is to affect economic geography and local development greatly. New cultural changes are characterized by variations from abstract discourse to concrete reality and show the emphasis on real project specific in the region. Further more, possibility of local development in the glocalization found in the specific form of cultural content, for example, Korean Wave. New media environment changes that include SNS function not only interact each other in space but also expand the scope of local units and cultural content to the world. In order to enhance the further development of local content, it will require conjunction with space and specific region, variety of organic link between the principal participants, and building infrastructure for future development.

  • Environment of marine transportation market is changing rapidly. Due to globalization of world economy, marine transportation of cargos, especially trade using container boxes, is increasing dramatically. Fierce competition in the global market of container transportation forces the shipping industry to seek the economy of scale to reduce transportation cost, and drives the merge and alliance of liner shipping companies. Mega-sized container ships, having capacity over 10,000 TEU, were introduced, and appeared recently, in order to reduce the unit transportation cost. Korean shipping and shipbuilding companies are competitive, and have considerable market share in the global market. Even though both industries are inter-connected through ships and have many common interests in order to enlarge the global market share, inter-relation between two industries is surprisingly insignificant. In this paper current issues in the process of environmental change of marine cargo transportation are reviewed, and inter-relation of shipping and shipbuilding industries is discussed. Suggestions for inter-related development of Korean shipping and shipbuilding industries are given, and means for mutually beneficial collaboration are suggested.

The Change of Site Pattern of Buddhist Architecture of Koguryo (고구려사지(高句麗寺址)를 중심(中心)으로 고찰(考察)한 5세기전후(世紀前後) 불사계획(佛寺計劃)의 변화(變化))

  • A few archeological excavation of Buddhist temple sites of Koguryo were reported with information of site arrangement. The interpretation of such information is very important not only for the explanation of Korea early Buddhist architecture but also for the development of East Asian cases in general since no archeological evidences of the same period were found in other countries such as China. Though the investigation of the four temple sites this paper attempt to identify their date of construction and the process of change. The study depended much on comparative studies of the change of site elements such as pagoda, image hall., corridor, and other buildings. The study could conclude that the site of SangO-Ri must be the earliest case which was followed by ChungRung-Sa, which was built in around 427AD. The site of ToSung-Ri was the case which was the work of the rate 5th century. Such process of the development of Buddhist architecture in Koguryo unveils the fact that the process of change was a continuous flow toward a consistent goal of change that had much to do with the contemporary religious situation.

  • This study seeks to find new strategies for the development of Tapgol Park and to identify Programs to promote this development. In addition, the study specifies the purpose and meaning of these efforts by revealing social aspects not apparent in the physical form of the site, and reading how these aspects influenced the development of Tapgol Park Because the focus of the study lies in reading cultural aspects of the site which have to be understood within the context of their social circumstances, the study drew materials from mass media such as newspapers and literary magazines, which best reflect these social aspects. Interpreting the over 100 you history of Tapgol Park in a cultural context, the study found a meaningful suggestion that such a small urban place located in a city forms a cultural identity in the course of communicating with its surrounding social situations. The change in the identity of Tapgol Park has been sensitive to changing social circumstances rather than the physical structure of the space. The original function of Tapgol Park as a traditional city park has gradually changed towards strengthening social functions, much like the character of an urban plaza. In the process of change the park developed a unique culture. This park culture, however, came not from the original design but from its close interactions with social circumstances changing over time. At the same time, the change in identity seen in Tapgol Park has not been fresh formed. It can be said that the inertia came into light with the potential powers under the place over the long history having been combined into the then social circumstances. In early 2002, the park re-opened, refurbished as one of the relics of the March 1st Movement. Investigating how cultural inertias that have been developing in various forms to date will change and be maintained in this new paradigm is an important assignment for researchers.

  • The analysis of environmental change followed by cultural development is useful for determining development plan hereafter. This study aimed for quantitative analysis about urban sprawl within 10 years, from 1984 to 1994, at Kwangju city, and to extract characteristics of change. For this purpose, we performed land cover classifications using Landsat TM data. And to evaluate influence of urbanization, we carried out surface temperature analysis using TM band 6 data. From the change analysis in land cover, it wa found that expansion of urban areas amounted to 3% and get accomplished by exploitation of farm land area, and that a rice paddy fields were changed to vinyl house areas considerably. In the regional aspect, development was concentrated on Kwangsan-ku which had been incorperated into Kwangju city in 1988. The results from temperature analysis showed that there was close correlation between surface temperature and land cover types, and that urbanization would influnce temperature to rise $0.3^{\circ}C$ in summer. As a results, we can prove that satellite data is very effective for environmental change analysis.

  • In this study, we compare and analyze the attributes of the software development cost model according to the shape parameters change of the Type-2 Gumbel lifetime distribution using the NHPP model. In order to analyze the software failure phenomena, the parametric estimation is applied to the maximum likelihood estimation method, and the nonlinear equations are calculated using the bisection method. As a result, when the attributes of the cost curves according to the change of shape parameters are compared, it is found that the larger the number of shape parameters, the lower the software development cost and the faster the release time. Through this study, it is expected that it will be helpful for the software developers to search for the development cost according to the software shape parameters change, and also to provide the necessary information for the attributes of the software development cost.
