This study is to consider the geographical images of Nakdong River region represented in the Modern Poetry. The findings are as follows. First, the change aspect of the poetry around Nakdong River area shows the social phenomenon of population movement, economic deprivation symptoms, the Korean War, economic development plans, the industrialization and spatial inequalities, environmental problems and environmental poetry, and various environmental issues, etc. Second, the poetry about Nakdong River can be classified by geographical area, showing a humanistic geographical image of the sense of place, natural geographical images about geomorphology and climate, and regional development and environmental pollution. Finally, the large number of poetry describes the beautiful terrain and the sense of place of poet, among ones targeting the upsteam of Nakdong River. The one in middle and downstream areas, however, reflected the reality and was social criticism mostly. This is because that, compares to the upstream, many large cities are distributed in the downstream area and the river becomes increasingly contaminated as it flows to the downstream.

Purpose: This study aims to propose a method for fast geographical origin discrimination between domestic and imported rice using a visible/near-infrared (VNIR) hyperspectral imaging technique. Methods: Hyperspectral reflectance images of South Korean and Chinese rice samples were obtained in the range of 400 nm to 1000 nm. Partial least square discriminant analysis (PLS-DA) models were developed and applied to the acquired images to determine the geographical origin of the rice samples. Results: The optimal pixel dimensions and spectral pretreatment conditions for the hyperspectral images were identified to improve the discrimination accuracy. The results revealed that the highest accuracy was achieved when the hyperspectral image's pixel dimension was $3.0mm{\times}3.0mm$. Furthermore, the geographical origin discrimination models achieved a discrimination accuracy of over 99.99% upon application of a first-order derivative, second-order derivative, maximum normalization, or baseline pretreatment. Conclusions: The results demonstrated that the VNIR hyperspectral imaging technique can be used to discriminate geographical origins of rice.

This study suggests that the contents and methods focusing on the leamer's geographical experience of everyday life and environments, are very effective for teaching and teaming in geography subject matter. The contents have to be selected and structurized from private geographies about their region of everyday life for teaming abstractive and scientific concepts of geography. Scientific concepts of geography, i.e. geographical concepts become 'scope'for selecting the contents and these systematic structure substitutes 'sequence'. The criteria by which selected contents of teaching and teaming based on everyday life may consist of three elements: region as leamer's place for everyday life; concrete experience of the place; and leamer's changing geographical experiences.

In recent academic debates within the UN Group of Experts on Geographical Names, two contrasting views evolved as regards to the status of the names of transboundary features or features beyond a single sovereignty. The partial view posits that a name is an endonym only for those portions of a feature where the name corresponds to the language used while the whole view argues that a name in its official language is an endonym for the whole feature. In either of these views, the name East Sea should be given due respect, for the Korean territorial waters at least or as an endonym for the entire sea. This paper supports the partial view that a geographical feature can be separated and each separated portion can have different name forms and status. Regarding the separation of a feature, the limits to which local people perceive as 'their' sea should be used. The name East Sea is proposed as the translated form of an endonym Donghae.

This study describes a methodology to develop a environmental and geographical information system for managing a national scale which is supports the environmental fate modeling. This system was developed via the integration of environmental and geographical information database(DB) and the DB usage software. For the sound environmental management, the DB were constructed by extracting the geometrical figures-such as points, polylines, and/or polygons-based on the geographical information previously developed in Korea. Then it was connected with the environmental information. Based on the Visual Basic Complier, the software can be a useful tool for visualizing the DB, for searching the environmental & geographical information, and supporting the environmental fate modeling.

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.

This paper is to elucidate geographical implications of fieldwork activities of everyday-life space of students of an elementary teachers college. The students depended mainly on questionaries and interview for gathering data during fieldwork. They had difficulty in processing data to visual-spatial representation, i.e. map, tables, and diagrams. But they were favourable for appling their fieldwork experiences to teaching the elementary geography. This is viewed as an unique behavioral orientation or desirable attitudes of students of an elementary teachers college. On the basis of the self-assessment and peer-assessment of fieldwork activities, it could be ascertained that the students came to understand the geographical value and significance of fieldwork activities. The fieldwork activities made them to heighten their interest of everyday-life space, and so to internalize positive their senses of place, to enforce their identities of place. According to the results of this research, we need to develop a systemic contents for fieldwork activities in geography curriculum of elementary teachers colleges.

As foreign immigrants are rapidly increasing, how they without previous knowledge and experience adjust themselves to local circumstances where they come to live becomes a major social issue. In order to analyze their adjustment process, this paper suggests a model which consists of relationships with local environment and people on the one hand, and of geographical knowledge and imagination on the other. The analysis of questionnaire survey based on the conceptual model suggests some findings. As there are considerable differences in the extent of their local adjustment and felt difficulties among immigration types, nationalities, and dwelling regions, foreign immigrants‘ policies should be devised proper for their type and characters.

In this study, we examine business start-up and closing business in a geographical context. In particular, we analyze the geographical characteristics of business start-up and closing business according to the type of industry. For the purpose, we use the last 10 years data that have been related with current economic situation since the financial crisis. In first, we identify the spatial distribution patterns of business start-up and closing business, We examine the difference between individual businesses and corporations. Finally, we construct general linear regression models and spatial regression models for them, and derive meaningful socioeconomic variables that explain their location distribution. The results of this study could provide basic data for regional planning of national and local governments that activate local economies as well as job creation.

The purpose of this study is to analyze key concepts of Entrepreneurial Ecosystems and to suggest implications for economic geographical studies. The definition and concept of entrepreneurship as well as changes of its research trends were examined. By combining entrepreneurship and geography, Entrepreneurial Ecosystems, which have recently emerged as important concepts and theories, were examined with the focus on the key concepts such as 'actors and factors', 'productive' and 'territory'. It is important that the individual, organizational and institutional components such as entrepreneurs, start-ups, existing companies, institutions and cultural elements are interconnected to build communities through 'entrepreneurial recycling'. Entrepreneurial Ecosystems support to create innovative high-growth start-ups based on entrepreneurial culture in the local region. Despite conceptual limitations, theoretical and empirical analyses should be conducted from economic geographical perspectives in order to reveal the geographical and spatial processes of productive entrepreneurship and to suggest policy implications for region-based start-up ecosystems.
