Due to the increased use of digital maps in the construction industry, there is a growing demand for high-quality digital map analysis. With the large amounts of data found in digital maps at earthwork sites, there is a particular need to enhance the accuracy and speed of digital map analysis. To address this issue, our study aims to develop new technology and verify its performance to address non-ground and range mismatch issues that commonly arise. Additionally, our study presents a new digital map analysis framework for earthwork sites that utilizes three newly developed technologies to improve the performance of digital map analysis. Through this, it achieved about 95% improvement in analysis performance compared to the existing framework. This study is expected to contribute to the improvement of the quality of digital map analysis data of earthworks.

When researchers plan R&D projects, they usually use patent map or paper map for the objective decision-making, but in traditional korean medicine field, domestic patents and papers have been mainly proposed as results of many R&D projects, while most of patent or paper map tools support international patents and SCI papers, respectively. Therefore, as an alternative one KIOM constructed the project map which can provide the technology landscape for R&D project information in traditional korean medicine field. But the functions of the system is limited to the search and analysis with chart. So sophisticated analysis results are hard to get from the existing system. This research's goal is to upgrade the web based project map analysis system to provide researcher rich functionality and advanced analysis tools.

수학교육에서 Concept Map(개념그림)을 활용하기 시작한 초기에는 Concept Map이라는 그림 안에 수학적 아이디어를 어떻게 표상할 수 있느냐에 초점이 맞추어져 있었다. 하지만, 최근 연구에 따르면 Concept Map이 문제해결력과 밀접한 관련이 있다. 구체적으로 Concept Map은 학생들 사이의 협력적 문제해결의 도구, 문제를 탐구하기 위한 도구, 문제의 구조를 소개하기 위한 도구, 지식의 체계를 개발하고 체계화하는 도구 등으로 사용될 수 있다. 이에 본 연구에서는 Concept Map에 대한 선행연구 분석을 기반으로 Concept Map을 활용한 수학 문제의 구조 분석에 집중하였다. 그 결과 수학 문제 구조 분석을 위한 Concept Map의 활용 방법을 개발하였고, 개발된 자료를 적용하여 실제 수학 문제 분석에 적용함으로써 그 실현 가능성을 확인하였다. 본 연구 결과를 통해 수학 문제 구조의 파악, 수학과 교육과정 및 교과서와 일관성 있는 문제의 개발, 수학 문제의 난이도 분석 등에 효과적으로 활용될 것으로 기대된다.

This study has been accomplished as a experimental study for field application of 3D Perspective Image Map creation using Digital Topographical Map and based on the Ortho-Projection Image which is generated from Satellite Overlay Images and the precise Relative Coordinates of longitude, latitude and altitude which is corrected by GCP(Ground Control Point). AS to Contour Lines Map which is created by Coordinate conversion of 1:5,000 Topographical Map, we firstly made Satellite Image Map to substitute for Digital Topographical Map through overlapping the original images on top of each Ortho-Projection Image created and checking the accuracy. In addition to 3D Image Map creation for 3D Terrain analysis of a target district, Slope Gradient Analysis, Aspect Analysis and Terrain Elevation Model generation, multidirectional 3D Image generation by DEM can be carried out through this study. This study is to develop a mapping technology with which we can generate 3D Satellite Images of a target district through the composition of Digital Maps and Facility Blueprint and arbitrarily create 3D Perspective Images of the target district from any view point.

Objectives: Because of the characteristics of traditional Korean medicine, there are few overseas patents and SCI papers. Researchers are struggling to analyze the research trend using existing patent analysis system and paper analysis system. We aim to build up a web-based paper map analysis system for Traditional Korean Medicine to improve the situation. Methods: We studied the following three sub topics. First, we surveyed the research trend analysis method for traditional Korean medicine. Second, we designed a paper map analysis model and made the algorithm for it. Finally, the development of the paper map analysis system was conducted. Results: We developed a web-based paper map analysis system which has the three main functions being analysis chart, topology map and contour map. For the rich internet application, we used the flex development tool and java integrated development environment. Conclusion: We will provide our paper map analysis system in the OASIS through the minor changes to provide easy use. We hope that this system will be a useful tool to analyze the research trends for traditional Korean medicine.

Report documents of industrial and occupational accidents have continuously been accumulated in private and public institutes. Amongst others, information on narrative-texts of accidents such as accident processes and risk factors contained in disaster report documents is gaining the useful value for accident analysis. Despite this increasingly potential value of analysis of text information, scientific and algorithmic text analytics for safety management has not been carried out yet. Thus, this study aims to develop data processing and visualization techniques that provide a systematic and structural view of text information contained in a disaster report document so that safety managers can effectively analyze accident risk factors. To this end, the risk factor map using text mining and self-organizing map is developed. Text mining is firstly used to extract risk keywords from disaster report documents and then, the Self-Organizing Map (SOM) algorithm is conducted to visualize the risk factor map based on the similarity of disaster report documents. As a result, it is expected that fruitful text information buried in a myriad of disaster report documents is analyzed, providing risk factors to safety managers.

Studies in social science are performed on the language of social actors. While a metaphor analysis focuses on the meaning of the language, a cognitive map analysis deals with its external relationships. If we can put together both analyses, it will be possible to investigate the internal meanings and external relationship of the language and image at the same time. In this paper, metaphor analysis and cognitive map approach is applied to find the image of local governments. This study shows how to link metaphor analysis to the cognitive map and the benefit of using both approaches together.
