최근 각광을 받고 있는 지도(이하 맵)를 활용한 서비스는 맵에 접근한 후 인터페이스를 통해 다양한 매쉬업 형태의 결과를 제공하는 방식이다. 이러한 서비스는 사용자에게 정확한 정보를 제공할 수는 있지만 맵의 재활용은 어렵다. 본 논문의 스케치맵 시스템은 기존의 대형 맵 시스템과는 달리 목적에 부합하는 특정 지점과 경로를 XML 문서로 표현한다. 또한, 스케치맵 간에 클러스터링 방법을 사용함으로써 맵에서 표현되는 지점을 최적의 내용으로 갱신한다. 그 결과로서, 목적지점에 대한 경로를 간단하게 약도로 표현하기 위해 설계된 맵 서비스 시스템이다. 본 시스템은 스케치 맵의 XML 문서 입력에 대하여 스케치맵 생성기에서 분석 분할 클러스터링의 과정을 통해 유효한 형태의 스케치맵을 생성한다. 스케치맵의 분할 및 병합을 위한 질의처리 방법으로는 LCS(Longest Common Subsequence) 알고리즘을 사용하였다. 또한, 본 스케치맵 시스템에 대한 기대효과를 시뮬레이션으로 제시하여 정보와 지식을 공유하는 보이는 맵들이 모여 거대한 맵을 형성함으로서 새로운 검색 포털로서의 역할을 수행할 수 있음을 보인다.

휴대폰의 지도서비스는 단말기의 해상도와 프로세스의 제약으로 인하여 데이터를 간략화하면서 사용자의 이해도를 높일 수 있는 약도의 제공이 보다 효율적일 수 있다. 약도는 출발지와 목적지의 경로를 중심으로, 주변의 중요한 도로나 지형지물 등을 단순화하여 사용자가 이해하기 쉽게 표현된 형태이다. 약도 서비스를 위해서는 우선 출발지와 목적지의 경로 및 그 주변 도로를 선택하여 약도식으로 간략화하는 방법이 필요하며, 단말기의 해상도에 적합하게 주변 지형지물을 간략화 된 도로와 함께 약도화하여 표현하는 방법이 필요하다. 이에 본 논문에서는 휴대폰에서 지도를 효율적으로 표현하기 위하여, 지도 일반화 개념을 이용한 약도화 방법을 제안하였다. 제안하는 약도 표현 방법은 현재 상업적으로 서비스되고 있는 지도 서비스와 비교하여 도로를 구성하는 노드의 수가 감소하고, 중요한 지형지물의 선택 등을 수행하여 데이터 효율성이 우수하고, 경로의 명시성과 이해도가 높은 것으로 조사되었다.

Driver centered vehicle design is the important factor for driver's safety, product quality, and so on. Therefore, people has recently recognized the importance of driver centered vehicle design. Especially, in the focus of driver-vehicle interaction system, it is very important factor to ergonomic design of vehicle cockpit. In this study, Sketch Map method was used to measure of driver's cognitive map on IP(Instrument Panel) that is the basic factor to ergonomic design for vehicle cockpit. The compatibility of Sketch Map method was validated for the measurement of driver's cognitive map and then the accuracy between two groups was analyzed using Sketch Map method. Subjects were divided in two groups, the first group of subjects has their own vehicles and driver license, and the second group of subjects doesn't have own vehicle but has driver license. The result showed that for the case of the first group, the shape of IP in the cognitive map was influenced by IP of their each vehicle. However, for the case of the second group, it showed the difference between IP in the cognitive map and IP of experienced vehicle many times because they have been driving various type of vehicle. So, the shape of IP in the cognitive map was influenced by various type of IP.

The information management system for urban planning, urban management and related decision making is increasing an importance in recent years. Especially, the information about 3D buildings in urban area is necessary for urban management related precise location based service. However, it takes a lot of time, effort, and costs to produce 3D modeling data of buildings. These problems have been found in many studies, but the research to solve these problems is still necessary. In this study, we have tested an efficient 3D modeling method of building to solve these problems. SketchUp was used to test 3D modeling methods with OSM(OpenStreetMap) data. The other 3D modeling method using a digital map was tested. The 3D modeling of building data was efficient using PlaceMaker, which can use OSM data. In addition, modeling was possible through simple editing of the digital map and automatic building generation. The efficiency of the research results is presented by comparing with the traditional method based on the regulation and the stadard man power issued by Korean government. These two 3D modeling methods of building tested through the study can be used as basic data for related research and work. Additional studies should be conducted to improve the accuracy of the building model and determine how to obtain height data efficiently.

The similarity of shape of shape of interface between human cognitive map and real product is the important factor to determine the human performance. Nevertheless, the degree of similarity between these has not been defined quantitatively in recent studies. Therefore, in this study, the cognitive map and the mental workload were measured by SMM(Sketch Map Method) and RNASA-TLX(Revision of NASA-Task Load Index). And the numerical expression of the accuracy point was suggested for the quantitative calculation of relative positional similarity between cognitive map and real product. In the experiment, nine subjects were participated and two kinds of vehicles were used. Mental workload was mental workload was measured immediately after the road test. The result of analysis on the relationship between accuracy and mental workload shows that the negative correlation exists on each vehicle, and the lower score of mental workloads id measured on the vehicle that has the higher score of accuracy between two vehicles.

Mobile network infrastructure is being completed with the development of hardware and software for mobile devices. Network in mobile devices has evolved for telematics that is expanded much more than its existing concept. Telematics is compound word that is formed from the words "telecommunication" and "informatics". It means that telematics performs control and monitoring service with using mobile device resources. These services provide their services for users' requests through wired or wireless network from mobile devices and server that offers contents and network service collects management information of mobile devices. Map service is one of the preferred services for many telematics users. However, mobile map service has a limit between traffic and information sharing. Therefore it is very important to supply their information for both service provider and terminal user. In this paper, we design a new interactive sketch map using routes and information on the space to be applied effectively, and provide an extended document format that is defined to an extensible and dynamic clustering scheme to have portability map service for mobile device.

최근 웹 기반 서비스에서 각광받는 분야 중 하나는 SNS로 불려지는 "인적 관계 서비스"이다. 이들의 관계를 표현하는 관계 지도 서비스는 오프라인 현실과 연동된 직관적인 자료이기 때문에 사용자에게 정보를 더 쉽고 시각적으로 전달해 줄 수 있다. 과거의 지도 서비스가 주로 물리적 현실 정보를 담고 표현하는 것이었다면 오늘날 지도는 실제 세계를 담는 단순한 검색 플랫폼을 넘어 사회관계를 표현하고 커뮤니케이션하는 새로운 플랫폼으로 진화하고 있다. 본 논문에서는 온라인 지도 서비스의 구조를 기반으로 스케치맵을 활용한 스마트 소셜 그리드 시스템을 제안한다. 본 시스템은 다양한 SNS를 위한 표준 인터페이스 제공, 확대된 소셜 그리드를 통한 인맥 네트워크 구성 시 거버넌스 허브 툴로의 활용, 여타 SNS와 연계한 매쉬업 소프트웨어와의 브리지 역할, 소셜 그리드 데이터를 재생산하도록 하는 사용자 환경 구축, 향상된 탐색 기술을 통한 보다 빠른 서비스 구축 등의 특징을 갖는다.

본 연구에서는 초등학교 수학교과의 전통적 교육내용인 겨냥도와 전개도에 대해 논의하였다. 우선 현행 2009 개정교육과정 교과서 일부 내용에서 난이도와 제시의도 등의 문제를 제기하고, 보다 일반적인 관점에서 겨냥도와 전개도의 위상에 대한 의문을 제기하였다. 이를 논하기 위해, 전개도와 겨냥도가 교육과정에 따라 어떻게 다루어졌는지 조사하였고, 외국의 교과서를 우리나라와 비교하여 살펴보았다. 이를 바탕으로 현행 교과서에 지금과 같은 내용이 들어오게 된 맥락을 고찰하고, 그림 표현의 문제, 입체도형 구성의 문제라는 관점에서 시사점을 논의하였다.

Chinese ethnic minorities are inheriting their own traditions based on thousands of years of community life. Yunnan province in china is a castle in which many ethnic minorities have been living on the basis of various natural environments. Their traditional village can be regarded as a place reflecting minorities' thousands year of history and culture, and elements of positive social spaces are seen from the old village. Streets and places of the village are accumulated as images for residents. Based on their imagination-concept, sketch maps, reflecting residents' cognitive perception were collected. Analysis of 21 sketch maps shows that architectural elements, forming a unique landscape and community life contribute to establish a unity of one nation. the oldest tree in the village has a strong specificity as a place with the belief that the tree protects all residents in the village. Space in the head of the residents and Social spaces, embedded in the memories of the residents living in the community continued organically and the roads of the village showed clear recognition. Following this, the analysis methodology of social spaces and sketch will be examined in depth.

Seongbuk Village and Ungcheon Village are Town Wall Villages that reflect social and historical backgrounds. villagers have formed villages based on community life. The streets and places of the villages are accumulated as images in the memory of the inhabitants. Based on their imagination-concept, 30 sketch maps, reflecting residents' cognitive perception were collected. Analysis of 30 sketch maps shows that other forming of Collective maps. In the past, Villages historical facilities had changed roles, but the relationship between the place and the place has been continuous, and according to the development process of the villages, the relationship between streets and places has been formed. Following this, the analysis methodology of social spaces and sketch will be examined in depth.
