This study attempts at building a GIS computing environment that incorporates object-relational spatio-temporal database for the time geography model with space-time path, space-time prism and space-time accessibility. The proposed computing environment is composed of ( i ) mobile GIS application for collecting spatio-temporal trajectory data of an individual, ( ii ) spatio-temporal database server that includes time geography model, and (iii) geovisualization client that performs time geographic queries to the spatio-temporal database. The spatio-temporal trajectory data collected by GPS-PDA client is automatically processed and sent to server through data management middleware. The spatio-temporal database implemented by extending a generic DBMS provides spatio-temporal objects, functions, and SQL. The geovisualization client illustrates 3D visual results of the queries about space-time path, space-time prism, and space-time accessibility. This study confirms the possibility of integrating mobile GIS and DBMS for time geography model, and it presents the appropriate database model with spatio-temporal objects and functions that may handle very large data for time geography application.

Health geography has gained importance due to healthy smart cities, regions, and the integration of geo-internet and blockchain technologies. This study explores the intersection of geography and health, focusing on specific health challenges faced by individuals and groups. Using observational and descriptive methods, the study takes a regional approach to illuminate the socio-economic factors that are critical to addressing global health challenges. Drawing on academic literature and practical research, a concise case study of health challenges in Uzbekistan is presented, offering valuable insights. The analysis of data from informative articles and UN publications highlights the interdisciplinary nature of health geography and its practical applicability for researchers and policymakers. The findings underscore the important role of geography and health sciences in addressing region-specific diseases while highlighting the importance of spatial analysis in understanding environmental hazards and health impacts, including disease outbreaks.

2015 was the seventieth year from the liberation and the division of Korean peninsular. Although the research on the unification has been performed in various interdisciplinary fields since the liberation of Korea, the geographic research on the unification based on the space stays in a minority. It is time to wrap up the literatures and discourses centered on geography for preparing the unification and taking a view of Korean territory of future unification. The starting point is to define the concept of the geography for unification and give careful consideration to the geographic research trends related to the unification that has been achieved since the liberation of Korea. The geography for unification should be understood in the concept of time and space. First of all, the geography for unification can be composed of the stages such as the research for unification, the research for unification impact, the research for united Korea, and the geopolitics of East Asia under the concept of time. It also can be divided into the regions such as Korea, North Korea, borderlands between North Korea-China and North Korea-Russia including South and North Korea, and North East Asia and Pan Pacific Ocean. The geographic research on the unification embracing the concept of time and space can be defined as the geography for unification. The purpose of this study is to elicit the concept and the research field of the geography for unification in the perspective of discourse, investigate the research trends by geographic themes, and suggest the agendas of the geography for future unification.

With the advancement of mobile information technology, the era of smart work emerges as a means for enabling us to overcome temporal and spatial constraints. Thanks to smart mobile devices with seamless access, organizations can assign tasks to employees and provide services to the appropriate customers in mobile environments. In addition, smart work facilitates the improvement of coordination and collaboration among individuals and groups performing organizational tasks. The dramatic performance improvement is manifest by utilization of smart work in organizations. Therefore, the interest in the introduction of smart work is growing. With the lens of time-geography, this study investigates what makes smart work successful. This research, especially, concentrates on the processes for overcoming the temporal and spatial constraints in the field. A case study of the Seoul Metropolitan Rapid Transit Talk and Flash (SMRT T&F) is developed and analyzed through the framework of time-geography and the implementation processes and success factors of SMRT T&F are investigated.

The paper examines the recent criticism from various viewpoints on landscape research in 'New cultural geography' focusing on the representation and duplicity of landscape as one of the key theoretical basis of the landscape school. The paper argues that landscape theories in new cultural geography should be considered as what is constantly changing over time and composed of various theoretical and genealogical elements rather than internally homogeneous, fixed, and closed system of knowledge. Through the recent 'phenomenological turn' of geography, landscape researchers explores a possibility of alternative approach to the existing theories and methods, which is so called NRT(Non-representational theory). The research objectives of the paper is to examine the theoretical and practical implications of such significant criticisms, which put emphasis on the idea of landscape as performance and practice rather than landscape as representation in cultural geography.

우리나라에서 대학에 지리학과가 신설되어 전문적인 교육을 실시한 지 어언 50여 년의 세월이 흐르고 있다. 50년이라는 세월은 하나의 학문을 정착시키기에 충분한 시간이었음에도 불구하고 지리학은 한국사회에서 그 연륜에 상응하는 인지도를 획득하지 못하고 있다. (중략)

This study attempts at prototyping and evaluating a geovisualization tool that summarizes and explores human activity patterns using spatio-temporal trajectory data collected from GPS receiver. A set of core conceptualization developed in 'time geography' is successfully represented by our prototype based on the notion of 'space-time cube.' The notions of 'temporal dispersion cylinder' and 'parallel plane plot' are also implemented to allow funker analyses of human activity pattern on the space-time trajectory. The capabilities of the geovisualization environment we proposed include the interactive and dynamic functions that support a variety of explorations on the three components of spatio-temporal data : space(where), time(when), and object(what).
