This paper reviews how geographers have embraced the information and communication technology and expanded their perspectives from real space to virtual space. Information and communication geography research on the wired internet infrastructure began in the late 1990s, but the tradition has not been succeeded for the wireless internet technology. While the relationship-expansion, reproduction, and constraint-between real and virtual spaces have been studied by virtual geography scholars, we need more empirical research to reveal to what extent the two spaces impact to each other. To empirically investigate the physicality of the virtual, it will be useful to combine information and communication geography and virtual geography. However, it should be noted that empirical studies in the subfields can be criticized as being data- or technological deterministic.

In this paper, we describe two exploratory examples in the use of Augmented Reality (AR) for geographical visualization regarding refinement of visual content in geography textbooks and learning motivation of geography students. Currently, teaching and learning materials with AR technology and their utilization in the geography classroom have become a new topic in geographical research themes, and this trend has increased. Adequate development and utilization of geographical materials is an important starting point for smart education research in geography. This paper describes the system and software, and the implication of marker AR applications for teaching and learning geography in the classroom. For the AR applications to be utilized in geography education, two marker based AR examples, virtual globe and visualization of topographical features, are presented and their utilization aspects are discussed. Finally, from the discussion stated in this paper, it can be inferred that AR is useful for exploring geographical materials, and marker based AR will contribute to progress in spatial science and geographical education research.

This paper is about implementation issues for use of the Internet technology in education. An examination of the current status of virtual university provides guidance for subsequent prototype development. A virtual university is the Internet based process by which students increase their specific knowledge and skills via electronic interaction with content and people. Virtual university enables colleges and universities to provide students and faculty with network access to courseware and educational materials on multimedia servers free from time and geography constraints. In this paper, we present a prototype instruction support system (ISS). The ISS consists of the following components in architecture: Internet, software, hardware, database systems, users, and workflow. The ISS also assists several functions as follows: lecture notes, register processes, attendance checks, built-in boards, grading systems, questions and answers, electronic libraries, chats, and search engines. Our work will provide a guideline for the development of a virtual classroom for distance education and learning.

This study aims to analyze the changes of goals and contents of middle school geography education following up the changes in the Korean social studies curriculum over time. The main findings are as follows. First, From the Syllabus period to the Third Curriculum, geography education, history education, general social studies education in the middle school social studies were directed and managed independently. However from the 4th to the 7th Curriculum, the demand for the virtual integration in middle school social studies increased sharply. Since 2009 revision, social studies suffered an identity crisis as integrated subject matter because history education was separated from the social studies and interdisciplinary units were abolished. In spite of much criticism, however, an odd form of social studies integrating geography and general social studies still remains. Second, the stronger the demand for the social studies integration in middle school, students' social studies learning load had become heavier due to severe competition with other areas to ensure more portion in the integrated structure of social studies. Since geography education did not reflect the new tendency of the geography in the integrated structure of middle school social studies, the gap between the geography and geography education has increased and knowledges of geography growing became separated from students' experience. In conclusion, the integrated structure of social studies in the middle school hindered the geography education development as it limited the autonomy of geography education in terms of curriculum development.

The purpose of this study is to explore inductively learning effects of virtual field trips(VFTs) programs developed by elementary school students under the theme of minerals and rocks, focusing on learning in virtual geological components. Ten students attending 'H' elementary school in the metropolitan area voluntarily participated. In order to develop a virtual field trips programs, pre-actual outdoor geological field trips were conducted and virtual field trips programs were developed. In this process, written data of students observing, all video recording and voice recording materials of the course in which students participated, VR development data, and post-interview data were collected. Data were inductively analyzed focusing on four areas(cognitive, psychological, geography, and technical components) of learning in virtual geological field trips. As a result, there were positive learning effects for students in four areas. This study revealed that the study participants were not just participants in virtual learning, but rather developed classes for virtual field trips programs, which had significant results in terms of authentic inquiry.

We simulate the geographical effects on the onset time of sea breeze at Suyoung and Haeundae districts by using the LCM (Local Circulation Model). The following can be found out from the numerical simulation on Case I (real terrain) which considered the real geography of Busan metropolitan area. Especially, as a result of analyzing the land breeze path, it could be found along the coastline as it flows out through low land coastal area. To find out more about the effects of terrain and geography on the onset time of sea breeze, the results of numerical simulation of virtual geography are as follows. In Case II (flat terrain), to find out how the terrain slope affects the onset of sea breeze, flat land and the ocean was considered. As a result, convergence of nighttime air mass at a Suyoung area and nighttime strong wind speed phenomenon was not shown. In Case III (modified flat terrain), to find out the effects of the irregularity of coastline affecting the onset of sea breeze, numerical simulation was carried out by simplifying the complex coastline into segments of straight coastline. So land breeze system and changing process of sea breeze after sunrise at Suyoung and Haeundae was simulated almost in a similar manner. Through this we could find the effects of coastal irregularities on onset of sea breeze.

In this paper, methods are proposed for creating a curved line in a navigation mesh, which is used in a windows based virtual reality or games. The main geographies used in a windows based virtual reality or games are created by using either grids or navigation meshes. When using grids, it is difficult to create a natural geography. Multiple grids are needed to ensure precise descriptions, which can result in system overload. A navigation mesh was developed to address this issue since the navigation mesh has the benefit of placing fewer loads on the system than a grid method. The drawback, however, is that the movements of character in navigation mesh are less natural. In this paper, a method for creating a curved line using round curves is proposed in order to resolve this issue. Using the methods for creating a curved line proposed in this paper in a windows based virtual reality or games will eliminate the unnatural or awkward movement of characters that arises in the use of a navigation mesh.

The goal of this investigation is to examine the matter as to how various cyberpolitical activities such as on-line civic participation, cyber parties, development and movement of civil society networks are appeared in cyberspace; and how political activities in cyberspace are associated with offline environment. This research was based on in-depth and open-ended interviews centering around 20s (32 interviewees) and the major results are as in the following. First, in terms of on-line civic participation, searching political issues occur in places, where internet users can access information easily relatively, and creating or reconstructing political information is identified in places giving stability or affinity to the public society. Second, even though each party's homepage for the channel of cyber parties has enough capacity as bridgespace, which takes charge of supporting f lows of people, goods, capital, and ideas, most of them don't play a role to establish virtual or real networks. Exceptively, cyber parties contribute to make temporalized places, where nobody takes the responsibility, somewhat. Third, the development and movement of civil society networks is divided into several segments according to political interests and tendency in online; furthermore, such a cyberpolitical activity influences human networks and the decision of major places for political activities in offline.
