    Joseon Dynasty’s Recognition and Cartographic Changes of Dokdo between the 17th and 19th Centuries

    Saangkyun Yi | 2019, 19(2) | pp.1~15 | number of Cited : 1
    "This study aimed to question the disagreement between the entity (Dokseom, Dokdo) and the names (Usan and Seokdo) while the name of Usan disappeared and that of Seokdo appeared and to analyze the images of Dokseom (Dokdo) appearing in the maps and other materials manufactured in the Second Half of the Joseon Dynasty and the names of Usan and Seokdo in the context of awareness and mapping of the entity to answer the questions about the entity of Dokseom and the names of Usan and Seokdo. Around the seventeenth century, the Joseon Dynasty was fully aware of the entity of Dokdo, which was indicated clearly on the maps as people at that time understood it. However, it seems that the long-term repatriation policy had made the geographical information about Dokdo somewhat uncertain for a hundred years or so. These problems were still found in 「Cheonggudo」 and the initial version of 「Daedongyeojido」 ; then, these repetitive errors were corrected by Kim Jeong-ho’s careful investigation around 1861. In summary, 「Dongyeodo」 and 「Daedongyeojido」, both of which are nationwide maps manufactured by Kim Jeong-ho in the Second Half of the Joseon Dynasty, have a clear indication of Dokdo."

    Ji Won Suh | Ahn, Sejin | Hyo-Hyun Sung | 2019, 19(2) | pp.17~39 | number of Cited : 1
    The purpose of this study is to identify the characteristics of naming on marine geographical features around the Korean peninsula by western countries during 1787 through 1910. In order to do this, firstly, we collected 11 journals of voyages, 5 survey reports, and 45 nautical charts, and 3 gazetteers published by Britain, France, Russia, and the U.S. Secondly, we chronologically summarized the history of hydrographic survey around the Korean peninsula based on these sources. Thirdly, 118 marine geographical names were extracted and the origins of them were inferred. Lastly, we classified 118 marine geographical names into four types: descriptive, emotive, shift, and commemorative (person, ship, non-living entity) in terms of name origins. Results were as follows. Firstly, the hydrographic survey of the Korean peninsula began in France in 1787, and was actively conducted by Britain, United States and Russia. The east coast was explored in detail by Russia, the south coast was conducted by UK, and the west coast was surveyed by France, UK, and the United States. Secondly, for naming types, commemorative person type (39%) was the most preferred one, followed by commemorative ship (21%, descriptive (13%), shift (11%), non-living entity (8%), and emotive (4%) types. Thirdly, western countries preferred commemorative type in naming marine geographical features, in particular, Russia and U.S were more concentrated in commemorative type than U.K and France were. Lastly, France and U.S showed decreasing trend of naming marine geographical features after 1877, on the other hand, U.K and Russia showed an increasing trend.

    East Asia Regional Geography of William Dampier

    JUNG,IN-CHUL | 2019, 19(2) | pp.41~51 | number of Cited : 0
    The purpose of this study is to examine the content of East Asian geography described by William Dampier who contributed to the development of Enlightenment geography. For this, I reviewed the geography contents of East Asia described by Dampier. As a result of the study, Dampier’s maps on trade winds and ocean current provide invaluable description about East Asian maritime information at the time, and he defined that typhoons and hurricanes were same phenomena as the same type of tropical storm. I have also confirmed that detailed information of politics, religion, commerce, etc. that can not be found in other navigation narrative is described. The contents dealt in his travel reports can be used as a material on the future study for the British perception of East Asia of the eighteenth century.

    The Effect of Thematic Map Design on the Understanding of Geographical Facts

    Jin-ok Yun | Kamyoung Kim | 2019, 19(2) | pp.53~63 | number of Cited : 0
    The purpose of this study is to provide practical evidences that thematic maps that do not comply with the thematic mapping principles can make it difficult for students to intuitively understand geographical facts and may even lead to inaccurate understanding of geographical facts. For this, a questionnaire was developed to evaluate the understanding of geographical facts by using thematic maps in secondary school textbooks, which did not comply with thematic mapping principles. The main findings were as follows. First, students showed difficulty in intuitive interpretation of data in thematic maps with color arrangements that do not follow data characteristics. Students also showed a tendency to interpret data in the light of contextual knowledge or personal experience rather than maps themselves. In addition, there is a possibility of incorrectly understanding the data due to color arrangements which does not fit the characteristics of the data. Second, in the case of the thematic map which does not reflect the critical value for the interpretation of the data in data classification, the students have difficulty in intuitively interpreting the data by attempting additional analysis. Finally, in the case of a thematic map displaying totals, the area difference of the basic spatial units in which the data are aggregated greatly influences the interpretation of the data, thereby causing the students to interpret the data represented on the map differently from the actual.

    The Spatio-temporal Dynamics Estimation of Economic Growth in Border Regions, China, using DMSP-OLS imagery

    Minho Kim | 2019, 19(2) | pp.65~77 | number of Cited : 1
    China has opened its doors to foreign countries from late 1970s, and it has experienced tremendous economic growth in recent years. Meanwhile, an economic-development gap between regions has emerged to be a socio-economic issue in the nation. This research investigated the spatio-temporal dynamics of economic growth, associated with Chinese border regions, using DMSP-OLS time-series imagery at the scales of neighboring countries, zones and cities. To do this, the sum of lights was calculated from the satellite images with inter-calibration, intra-annual calibration, and inter-annual calibration. In addition, subsequent spatio-temporal analyses were made on the basis of coefficient of variation, annual average growth rate, compound annual growth rate and SOL-weighted centroids. This study found the decrease of economic growth gap between border zones. On the contrary, it was also revealed that unequal city-level growth in economy still remains in border regions of China. Such a socio-economic problem might be influenced by geopolitical relationship between the nation and neighboring countries. Both DMSP-OLS and SNPP-VIIRS DNB nighttime imagery would need to be incorporated in future research for making spatio-temporal analysis spanned to the most recent year.

    Study on Improvement Plan of Korean Geospatial Information Education Systems for Developing Countries

    Byeongsun Kim | Kirl Kim | 2019, 19(2) | pp.79~89 | number of Cited : 1
    The government officials of developing countries such as Cambodia that has not made its own map have been dispatched to Korea every year to learn advanced geospatial information of the Republic of Korea. This fact means that the international demands in geospatial information education have been increasing. The purpose of this study was to propose the improvement plan of educational policy to more systematically share experience and transmit technologies of Korean geospatial information for developing countries. It derived implications through analyzing the current status of geospatial education in Korea and overseas for developing countries. In addition, the survey of satisfaction level for the trainees who had finished the training course of the NGII (National Geographic Information) in cooperation with KOICA (KOrea International Cooperation Agency) was performed to elicit major issues in geospatial education for developing countries. Based on this analysis, this study suggested three strategies such as improvements of the education curriculum, the construction of education infrastructure facilities and the development of education service platform. It was judged that the results of the study could be contributed in not only enhancing the status of Korea as donor country of OECD members but also supporting expansion of overseas markets of Korean geospatial information industry.

    Building-level Estimation of Workplace Population using Household Travel Survey Data

    Yelin Kim | Hong Seong-Yun | 2019, 19(2) | pp.91~104 | number of Cited : 0
    Recently, individual-level analysis and demand for fine-scale spatial data have increased, but most of the currently accessible data is aggregated on the basis of administrative units. In order to overcome these difficulties associated with data procurement, this study proposes a method to generate fine-scale spatial data by integrating easily accessible open data. The building selection algorithm that estimates the destination of a trip by building unit is based on areal interpolation and dasymetric mapping. The weights for the building selection process are derived from various ancillary data. The results showed that the proposed algorithm is more accurate than the existing interpolation method. This study suggests a new population estimation model based on trip records and has a significance in that high-resolution data is generated by combining various easily accessible data.

    The Spatio-Temporal Distribution and Housing Conditions of a Gosiwon in Seoul

    Hyeongmo Koo | 2019, 19(2) | pp.105~118 | number of Cited : 3
    Living in non-dwellings violates a right to housing by offering inadequate housing conditions. This article analyzes the spatio-temporal distribution and housing of a Gosiwon, which is the most frequent type of non-dwellings in Korea. First, the result of a spatial kernel density estimation finds four clusters. The spatiotemporal kernel density estimation provides a further evaluation of the clusters, specifically, one relatively recent cluster around Daehak-dong, and older clusters around Yeoksam-dong and Sinchon-dong. Second, a cross type nearest neighbor distance function examines statistically significant spatial clusters from the Gosiwon to subway stations and universities within 90-940, and 210-730 meters, respectively. Finally, the housing conditions and facilities of the Gosiwon are summarized, which shows the minimum size, and the highest rental fee, and the most inadequate housing conditions in Seoul.

    Spatial Data Improvement Schemes of Open Data Portal

    Jeong, Jae Joon | 2019, 19(2) | pp.119~132 | number of Cited : 0
    Since the Korean open data portal service was launched in 2013, the level of data openness has expanded qualitatively and quantitatively, and numerous applications using open data portal have been developed. Since 70-80% of administrative data is location-related information, most of portal data also have spatial information. This study proposes spatial data improvement schemes of open data portal. To do this, at first, the 3 data types(file data, open API data, standard data) provided by open data portal was analyzed, and then status and problems of spatial data in portal were analyzed. Through status analysis, this paper suggests some improvements schemes. At first, a system for determining the data type, information level, and format of data should be established. Secondly, it is necessary to diversify data management institution and examine relevance of the data format. At last, in terms of the use of spatial information, the exact information of reference system should be provided and an integrated API for transforming the location reference system should be developed, and the handling process of irregular location reference system should be examined.

    Impact of Remittances on the Left Behind Families in Nepal: A Case of Vyas Municipality, Tanahun District

    Kanhaiya Sapkota | 2019, 19(2) | pp.133~146 | number of Cited : 0
    This paper examines why and how labor migration from Vyas Municipality, Tanahun, Nepal has mastered changes for the left-behind as well as in their community. The information was collected via interview by using a semi-structured interview with 175 migrant households through snowball sampling method. Focus group discussion and key informant interview also conducted for the in-depth information about remittance and its relation with the social changes of left-behind family members. Descriptive as well as inferential statistics were carried out to analyze the impact of remittance. The research finds that the remittance impacts positively on the social and economic conditions of individual migrants as well as their left-behind families. Improvement in the economic status of migrant households, the involvement of the household in community development activities, and participation of the household in social organizations have brought a positive change in the overall socio-economic status of the migrant households. The potential of migration to impact on other aspects of living conditions, social change and development at community levels are shaped and often limited by existing structures of power. The impact of remittances on economic and the social status of the sampled households is remarkable. The perceived status of the household in the post-migration period is better than that in the pre-migration period. For this purpose, one hundred and seventy-five households having migrant family member were selected for the household survey.
