This study employs three (degree, betweeness, closeness) centrality, network density, and assortativity measures in the network analysis, in order to evaluate international connectivity of airports and air carriers operating in the three countries. The main results are as follows. First, ICN (Incheon International Airport) is positioned as a top-tier airport among major airports in Asia, in terms of international connectivity evaluated by the three centrality measures. Also, we confirm that the connectivity of secondary hubs in China and East Asia markets has rapidly increased from 2015 to 2019, according to increasing routes connecting between those regions. Next, through comparing major airports’ networks of the three countries in East Asia, we find that in Korea the centrality gap between ICN and the rest of international airports is larger than gaps among major airports in the counterparts, mainly affected by their hub network structures. However, LCCs (Low Cost Carriers) in Korea have the smaller dependence on ICN than FSCs (Full Service Carriers) according to operating regional airports as their secondary hubs. From the results, we confirm that it is necessary to pursue improving the international connectivity of regional international airports through expanding LCCs’ air networks as a suitable strategy to improve the accessibility to international flights for local residents, as well as to alleviate the imbalance of the national airport system.","PeriodicalId":132041,"journal":{"name":"Journal of the Korean Cartographic Association","volume":"1 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2020-12-31","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"129729638","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

The slopes of the mountain are partially covered with talus and block streams consisting of large basalt bouders. The geological features of this mountain have been investigated in detail. However, their overall distribution patterns and development processes are not well known. This study aims to classify these bouldery landforms through mapping the location of basalt blocks, the analysis of the morphological characteristics of the slope, and field surveys on the large boulders. The exposed boulders are concentrated in the western valleys of the mountains and are rarely found in the eastern slopes. Field data show that all the boulders are composed of basalt rocks with columnar joints, and that there is a long-axis isotropy related to the elevation and gradient of slope. In addition, the result of TPI and slope analysis for DEM indicate that block stream was mainly distributed along the valley, and the talus appeared in the steep ridge and the lower part of the cliffs. The slope classification indicates that flat mountain tops, basalt cliffs, talus, and block streams develop in sequence, as the distance from the center of the mountain increases. The bouldery landforms of Unbongsan Mountain illustrate the process of slope change that appears as a slope retreat in a volcanic edifice.","PeriodicalId":132041,"journal":{"name":"Journal of the Korean Cartographic Association","volume":"24 1 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2020-12-31","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"130286124","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

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.","PeriodicalId":132041,"journal":{"name":"Journal of the Korean Cartographic Association","volume":"201 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2019-08-31","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"123013016","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
