지도는 기호, 주기, 색상, 경위선, 축척 등과 같은 여러 요소들을 사용하여 지도 사용자들에게 다양한 지리적 사상들(geographic features)의 존재와 그들의 상관관계를 전달하는 일종의 의사소통 수단이다(황철수, 2002). 주기(label)는 $\ulcorner$지역, 인공물, 자연물의 고유명칭 및 고유명이 없는 것의 종류 또는 상태 등을 표시하는 설명 및 표고와 등고선수치 등을 문자 또는 숫자로서 표기하는 것1)$\lrcorner$, 즉 지도에 나타나는 사상들에 대해 설명하기 위해 입력되는 문자열을 의미하는 것으로 지도의 여러 가지 요소들 중에서도 가장 직접적이고 구체적으로 사상을 표현할 수 있는 요소이다.

We propose a method for geographically enhanced representation of social networks and implement a Web-based 3D visualization of geographical contexts in social networks. A renovated social network graph is illustrated by using two key components: (i) GWCMs (geographically weighted centrality measures) that reflect the differences in interaction intensity and spatial proximity among nodes and (ii) MSNG (map-integrated social network graph) that incorporates the GWCMs and the geographically referenced arrangement of nodes on a choroplethic map. For the integrated 3D visualization of the renovated social network graph, we employ X3D (Extensible 3D), a standard 3D authoring tool for the Web. An experimental case study of regional R&D collaboration provides a visual clue to geographical contexts in social networks including how the social centralization relates to spatial centralization.

This study investigates the ontology-based public participation GIS(PPGIS). The major reason that ontology-based GIS has attracted attention in semantic communication in recent year is due to the wide availability of geographical variable and the imminent need for turning such recommendation into useful geographical knowledge. Therefore, this study has been focused on designing and implementing the pilot tested system for public participation GIS. The applicability of the pilot tested was validated through a simulation experiment for history tourism in Guri city Gyeongi-do, Focused on the methodology, the life cycle model which involves regional statues and user recognition, can be viewed as an important preprocessing step(specification, conceptualization, formalization, integration and implementation) for recommended geographical knowledge discovery by axiom. Focusing on practicality, ontology in this study would be recommended for geographical knowledge through reasoning. In addition, ontology-based public participation GIS would show integration epistemological and ontological approach, and be utilized as an index which is connected with semantic communication. The results of the pilot system was applied to the study area, which was a part of scenario. The model was carried out using axiom of logical constraint in the meaning of human-activity.

Social geography in Korea has been studied centering around urban social geography which has been developed mainly in English world, and then there have been a few concepts and theories that were tested in the rural social geography of Korean rural landscape. This article tried to grasp the conceptual basis of German social geography, and had views on the rural social geography in the relent English world. As a result, the author concluded that the rural landscape would be a representation of rurality, a component of local and national identity, and thought to be not only a physical reality but social, mental, cultural reality On the basis of this consideration, the author explored major concepts which would correspond with the universality and speciality of Korean rurality. They are as follows: 'lineage group' as a geographical socio-group, the 'regionalization' by social groups, and 'the territoriality of settlement' as a social space.

The purpose of this study is to introduce the concept of the geographic center, to examine its value as locational resource, and to consider the way of its practical uses. Geographic center is the intersection point where central meridian and central parallel cross each other. This geographic locational resources can be used as data for locational education in geographic education, the standards for antipodes, datum points for geodetic surveying, a factor of place marketing, etc. This study can be a model for a geographic discovery that is to seek many geographic resources being scattered about our country.

A lot of city have different characteristics in their location, space and environment each other. These characters are the factors showing inherent placeness of each space, and those factors should be reflected sufficiently in urban planning and development. Nonetheless, there are many parts that are not actually reflected in the plan, and this creates a space of unexpected arming. Especially, port area in a port city has strong characteristics of culture, history, geography and environment of the city concerned so it must make more creative and unique space. Therefore, it is considered that not only the physical factors but also the social factors should be actively reflected to highlight the place character of the port space. In this paper we are to construct the factors forming the placeness of port space based on the Form Based Codes rising as a flexible urban planning method in order to avoid rigidity of existing use district zoning system, and establish the placeness character of each port area.

실제 공간에서 네트워크를 통해 지역적으로 산재해 있는 통신 노드들에 관한 최단거리 문제 등을 위시한 각종 지리적 요소를 지니고 있는 문제들을 다루는 것은 복잡할 뿐만 아니라, 환경 및 상태 의존적이라 용이하지 않다고 할 수 있다. 본 논문에서는 네트워크를 통해 존재하는 실제 공간상에서의 지리적 성격의 문제를 특정 공간상의 문제로 매핑하여, 형식화(formalization)함으로써, 그 공간상에서의 수학적 문제로 변환하여 접근할 수 있는 효율적이고 간단한 방법을 제안한다. 그리하여 인터넷상에서의 2 노드 간의 최단 거리 문제를 위한 접근으로서, 본 논문에서 제안된 공간상에서의 두 노드 간의 수학적 거리를 정의하여 정형화된 수학적 최단거리를 구하도록 한다.

Most of global citizens in the globalization era want to live peacefully in the symbiotic relationship among each region or locality with its identity. From this perspective, the new regionalist models of development such as new industrial districts, industrial clusters, regional innovation systems, and global city-regions isn't helpful to most of regions because they were developed to increase the global competitiveness of industrial region from a few advanced industrial areas. This study attempts to develop 'regional differential development' as an alternative regional development theory. This theory puts emphasis on the truth that the difference or differential industry between regions in the real world connotes two essential values of development like the symbiosis of global citizens and the regional identity. Regional differential development seeks the development of regional differential industry on the basis of geographical elements with differential advantage, and hence it reviews significantly geographical elements including location, natural environment(landform, soil, climate, etc.), natural resources, population, transportation, culture, and landscape which appear substantially differently among regions. And to realize regional differential development successfully, it is crucial that actors(government, company, related institutions, and regional residents) actively participate and play each complementary role in the relationship of cooperation and conflict. Further study needs to secure the universal validity of this theory through many empirical studies.

지리정보를 정보시스템에서 사용하기 위해서는 복잡한 실세계의 형상을 단순화, 일반화하여 전산적으로 처리할 수 있는 정보구조로 변환해야 한다. 기존의 2차원 GIS에서는 실세계의 형상을 점, 선, 면 등의 2차원적인 형상으로 수치 정보화 하여 GIS 기능을 수행하고 있다. 하지만 지구상에 존재하는 지리적인 요소들은 3차원적인 공간정보로 구성되므로 이를 2차원으로 추상화시키면 많은 정보의 손실이 일어나게 되며, 기존의 2차원 GIS는 근본적인 한계가 존재하게 된다. 따라서, 실세계의 3차원적인 지리요소는 컴퓨터 상에서도 3차원으로 처리하는 것이 지리요소가 원래 지니고 있는 정보의 손실을 최소화 할 수 있으며, 실세계의 자연물 및 인공 시설물에 대한 3차원적인 표현과 분석을 위해서는 궁극적인 형태의 3차원 GIS가 필요한 실정이다. 이에 본 연구에서는 점, 선, 면 등의 2차원적인 형상을 3차원 공간 데이터로 수치 정보화 하기 위한 수단으로 VRML(Virtual Reality Modeling Language)을 이용하여 Virtual GIS 적용을 위한 3차원 가상세계를 생성함으로서 각종 의사결정을 보다 효율적이고 시각적으로 행할 수 있는 공간데이터를 작성하고자 하였다.

다양한 신재생 에너지 발전 중에서 수력발전은 풍력발전과 더불어 탄소배출이 가장 적은 에너지 발전 중 하나이며, 정부의 "2050 탄소중립" 발표에 따라 근래 수력발전에 대한 관심이 증폭되고 있는 추세이다. 하지만 국내의 지리적 특성상 수력발전의 규모가 국외에 비해 소규모이며, 대규모 수력발전의 경우에도 설치가능지역이 고갈되어 다수의 소규모 수력 발전소 설치라는 방향성이 불가피한 현실이다. 이에 따라 본 연구에서는 유한요소법을 이용하여 소규모 수력발전에 가장 많이 사용되는 콘크리트 댐 형상에 대한 구조해석을 실시하고 정수압 하에서 각 콘크리트 댐의 변형 거동 및 안정성을 분석하였다.
