Dokdo began to be clearly known to the West in 1855 when it was discovered by the British Hornet and the French Constantine. What has been known is only the fact that it was discovered by these Western fleets in 1855, and any detail of the discovery was not reviewed. The purpose of this study was to shed new lights on the course of Dokdo discovery by the Hornet and the Constantine as well as on the background of the Anglo-French combined fleets' advance into the East Sea from the perspective of the world history in the historical context of their dispatch to chase Russian fleets during the Crimean War, determine the geopolitical importance of Dokdo at that time, and investigate the course of Dokdo’s being reflected in modern Western cartography. This study obtained the following results: First, the Anglo-French combined fleets used operations to chase Russian fleets, with Hakodate in Hokkaido, Japan as their base, during the Crimean War. Second, Dokdo had a strategic importance in terms of location and was valuable as a milestone on the route while the Anglo-French combined fleets implemented their operations. Third, the British and French Naval Departments attached importance to the location and characteristics of Dokdo around 1855 and such countries as the United Kingdom, France, Russian, and the United States shared information about Dokdo, making its existence formal around the globe.

The Korean national police had to go through vicissitudes from the beginning because of the unstable domestic situation. The period from independence, the division of North and South, and the Korean War to 4.19 revolution and 5.16 coup was the chaotic period not only for the police but for all sectors of our country. Due to this situation, the history of Korean national police could not be properly established. So after the chaotic period, many researches related to the police has been conducted, but there are still many errors in those researches. I searched for various police-related data, collated them, and tried to identify and correct the errors. Although many achievements have been made in this paper, it was not easy to accurately identify the history of Korean national police with the efforts of individual researchers. Therefore, for the correction of errors related to police history, active attention and support from Korean national police agency is urgently needed.

Establishing the land and environmental plan based on the data-based scientific and objective analysis is necessary to ensure sustainable land preservation and use. The analysis results and forecast using the past and present data can be used for environmental policies in various areas. The Environmental Conservation Value Assessment Map (ECVAM), which evaluates the environmental value of land in five grades each year, has been constructed since 2005. Therefore, it is valuable data for predicting the future land change based on the past status related to the assessment of the environmental value of the land. The ECVAM uses 7 environmental and ecological assessment items and 57 legislative assessment items to deduce the land environmental value rating throughout Korea and updates them twice a year. However, the ECVAM is currently managed with a file system and has management and utilization limits in storage, updating, consistency, common use, and speed. As such, this study designs the data model for the efficient management and utilization of the existing file system-based ECVAM and suggests how to store, manage, and utilize the spatial DBMS-based data. To examine the practical applicability, we deduced the structured data for the query analysis and predicted the urban region expansion throughout Korea using logistic regression analysis. We are confident that the service for storage, management, and utilization of spatial DBMS-data not only manages the spatial data that are continuously generated and updated but also can be used in various areas such as the policies for land and environmental plans.
