  • One of the most important functions digital libraries need to offer is to help users find necessary information in a distributed environment in the most efficient and effective manner. In order to meet the goal, it is desirable to link scattered pieces of information and present them as a logically coherent whole when the user wants it, so that he or she doesn't need to know their physical location. The virtual document is an integrated document that the total or part of the physical documents stored in a specific repository are linked dynamically. Our MIRAGE-III digital library system provides a content-based retrieval of physical documents and the virtual documents in XML. This system provides a retrieval of partial documents, attributes and hierarchical structures and linked-documents based in structured documents like XML or SGML. In this paper we describe a methodology of design and implementation of the query processor and retrieval server in the MIRAGE-III digital library system.

  • 2020년의 경우 대기 상층 제트기류가 크게 강화됨에 따라 작은 규모의 저기압의 발달이 평년보다 두 배 이상 증가하였고, 그로 인해 장마가 최대 54일가량 지속되며 1조 371억 원 가량의 대규모 침수피해가 발생하였다. 이와 같이 최근 기후변화로 인한 이상 기후가 빈번하게 발생하고 있으며, 그로 인해 홍수, 태풍과 같은 재난의 강도 및 파급되는 재산피해가 점차 증가하고 있는 추세이다. 따라서 본 연구에서는 기후변화를 고려하여 향후 30년간 강우량 변화 추이를 파악하고, 이에 따라 파급되는 재난피해 규모의 증가 추세를 확인하고자 하였다. 기후변화 시나리오는 IPCC AR6(Intergovernmental Panel on Climate Change - Sixth Assessment Report)에서 제시하고 있는 시나리오 중 극한 시나리오인 SSP5-8.5와 안정화 시나리오인 SSP2-4.5 시나리오를 활용하고자 하였다. GCM(General Circulation Model) 자료는 전 지구적 모형으로 공간적 해상도가 낮은 문제가 있기 때문에, 국내 적용을 위해서는 축소기법을 적용해야 한다. 본 연구에서는 공간적 축소를 위해 통계학적 기법 중 인공지능 기법을 적용하고 Reference data와 종관기상관측(ASOS)의 실측 강우 자료(1905 ~ 2014년)를 통해 학습된 모형의 정확도 검증을 수행하였다. 또한 연 강수량과 연도별 홍수피해의 규모 및 빈도를 확인하여 연도별 강수량 증가에 따른 피해 규모의 증가를 관계식을 도출하였다. 이후 최종적인 축소기법으로 모형을 통해 향후 2050년까지 부산광역시의 예측 강우량을 전망하여 연 강수량의 증가량과 피해 규모의 증가량을 전망해보고자 하였다. 본 연구 결과는 부산광역시의 예방단계 재난관리의 일환으로 적응형 기후변화 대책 수립에 기초 자료로써 활용될 수 있을 것이다.

  • Augmented reality game has differences with traditional games in the way what it includes physical risks happened in the real world. Although accidents related to Pokemon Go are increasing, academic discussions on the issues are rare. Thus, this study explores risk types caused by the augmented reality game and examined how perception of the risks affect usage intention on the game. This study also provides the research implications through comparative analysis between youth group who generally has the tendency toward game addiction and older group. According to the results, teenagers had less usage intention when perceived financial risk increase. In case of over twenty, time risk had negative relationship with usage intention. Physical risk had no significant effect on usage intention for teenagers, but positive relationship was observed in case over twenty. These results imply the necessity of an appropriate regulation for safe game play.

  • This study developed a method which recognizes emotional interactions from the social distance by a beacon wearable device. The recognized interaction was evaluated by comparing with the cardiovascular synchrony from photoplethysmogram (PPG). The interaction was recognized when social distance was maintained for a certain period of time. The cardiovascular synchrony was estimated by correlation anaysis between beat per minute (BPM) from PPG. The maintenance time was determined by Mann-Whitney U test between the cardiovascular synchrony of interaction and non-interaction groups. Fifteen groups (2 persons per a group) participated in the experiment and they were asked to wear the beacon and PPG wearable devices in daily life. Experimental results showed that the interaction groups had more higher cardiovascular synchrony than non-interaction groups and the significant interaction time was determined to be 11 seconds (p=.045). Consequently, the real-time measurement and evaluation of the social network in real space was expected to be improved.

  • This study was initiated with the attention of demanding new and diverse approaches, we're talking familiar with imitations in the design process like a way to draw a image. So I studied a convergence of humanities and visual arts with the understanding and conceptual approach of the formless. The purpose of this study is to develop formless languages and to organize practical courses which are to enable deeper research and design expression on theoretical approaches and explanations of outcomes required before and after the process when we practice in connection with the formless. The method of this study is to draw detailed items from selected words through advanced researches, work and author researches and practice teaching. The results of the study I proposed the formless language that is related to the horizontality in spatial positioning system, and pulse in the separation of space and time, and entropy in structural orders of the system, and base materialism in the limitation of matter as the operating mechanism and parent item of formless. And those elements are related with shape, size, shading, color, texture, space, structure as visual elements of formative elements and those have various adjectival meanings as the subordinate concept. So I presented an education materials of basic design which is to enable understanding and expressing the formless language in the overall process of formless visual art(theoretical approach, practice course, presentation, etc.). Based on these study results, I hope that this educational materials will be used as educational contents that makes them express and understand different new beauties, and a role that reveals social identity, and a reference for research on a formless visual arts.

  • As Korean traditional peasant farming has come to a commercialization since 1970s, the spatial structure of Korean agriculture also has been gradually restructured by principle of not subsistance but economy. This epochal transformation of agriculture and its spatial structure in Korea are comparable with the first agricultural revolution in Europe. Facing this turning point, it is essential to redefine the nature and significance of agricultural geography in Korea through the review of the outcomes of about 200 studies published since 1950s in Korea of which twelve is concerned with locational analysis. The purpose of this study is to review the trend and characteristics of location studies on Korean agriculture. Major findings are as follows: (1) Since 1950s the location studies of agriculture recorded only 12 papers which occupy no more than 6% of studies of agricultural geography in Korea. This fewness suggests that the location study of agriculture in Korea is yet at the stage of beginning. (2) In spite of the fewness the studies, carried out mainly in 1980s, contributed considerably to clarify the locational characteristics of Korean agriculture especially in the spatial variations of crops, dairy farming and cropping system, the impacts of agricultural labors, the location strategy of mountain agriculture, and the responses of farmers to hazard. (3) In approach and methodology, two thirds of the studies has taken traditional empiricist view and other, positivist. And most studies adopted classic and neo-classic locational theories as their theoretical base in description and explanation. In degree of development, the location studies of agriculture in Korea seems to be about 20 years delayed compared to that of the advanced countries in terms of approach and methodology. (4) Such tradition of the location studies reflects not only the conservative nature of agricultural geography of Korea but also the early stage of capitalism of Korean agriculture.

  • This study attempted to conduct the study from a macro perspective more specifically through the temporal and spatial analysis of Minbuk villages according to a change in a Civilian Control Line, such as a social and spatial distribution and a change of the existing Minbuk villages. To this end, this study conducted the spatial analysis for the change in the Minbuk villages according to the adjustment of the Civilian Control Line in time series by using a map of the Armistice Agreement Vol. 2, Google Earth, a digital cadastral map, an administrative district map, and the like are used as spatial data, and summarizing and constructing, as attribute data, a statistical yearbook, Ministry of Defense and Cheorwon-Gun notification data, a Land Use Regulation Information System, and cadastral map attribute information. After the enactment of the Military Facility Protection Act, the analysis was performed on a 20-year basis based on the 1976 statistical yearbook of which the Civilian Control Line was drawn. As a result, the total area of the Civilian Control Zone in Cheorwon from 1975 to 2015 decreased by 105.8 km2, and 9 of 14 Minbuk villages were released and only 6 villages existed. The unoccupied villages were analyzed as 14 villages, 10 fewer than the existing surveyed or statistical villages. The movement of the Civilian Control Line to the north may disappear the unique characteristics of the Minbuk villages but should be done carefully as it is closely related to the lives of the current residents, and policies should be established in terms of sustainable development and conservation of the villages. This study is significant in conducting the temporal and spatial analysis, which is the basis of the Minbuk regions and the Minbuk villages, and may be used as basic data necessary for subsequent analysis study.

  • The Riparian Buffer Zone(RBZ) is a sustainable social-ecological system created in the middle zone between water and land. For the RBZ, close communication with the local community is important, and it is necessary to promote it as a communicative environmental planning process. In this study, for the RBZ project, three strategies are presented as a communicative act to understand and implement planning. First, government-led projects were avoided and improved to a process in which citizens and stakeholders participated together, centered on local partnership. Second, it was intended to introduce design criterias in terms of enhancing the function of ecosystem services that citizens can sympathize with, and to increase acceptance and awareness through the planning of preferred spaces and facilities. Third, after a balanced plan for habitats, water cycle-based ecological environment, ecological experience and open space, citizens felt the restoration effect and value as an ecological resources, and a system was prepared to participate in the operation and management. This study will work as a process model based on citizens's participation. In addition, it will be possible to provide lessons for the change of the policy paradigm for the RBZ and the implementation of similar projects in the future.

  • In this study, web document frequency of city place name is analyzed and it is used as the dataset for rank-size analysis. The search keywords are compared in the context of spatial meaning and the different domain corpus is applied. The acquired search results are applied for the further analysis. Firstly, the rank-size analysis is applied to compare the result between population and document frequency. Secondly, in case of correlation analysis, the significant changes are revealed when the spatial criteria for search keywords are increased. In case of corpus, COM, NET, and ORG shows the higher coefficient values. Lastly, the cluster analysis is applied to classify the list of cities that shows the similarity and difference. These analyses have a significant role in representing the rank-size distribution of city names that are reflected on the web documents in the information society.
