This paper tried to delimitate the location and scope of Nokdundo located in the Dumangang estuary. In 18th century, Nokdundo was an alluvial island formed by several tributaries divided from the mainstream of Dumangang. In the mid-19th century, Nokdundo was connected to the Russian territory because some tributaries were blocked by sediment flows. In many maps published in the Joseon Dynasty, the location and size of Nokdundo had not been depicted consistently with each other nor been described correctly. Because of the recurrent extinction-generating phenomena of waterways of the Dumangang due to sedimentation process, the location and scope of Nokdundo can be delimitated differently according to the era. According to the distance information of the records published in the 19th and 20th century, the scope of Nokdundo can be extended widely to the Maritime Province of Siberia. So, the author have set the Sodumangang(Karasik River) as the northern boundary of Nokdundo. The Karasik River is called Sodumangang by the Koreans living in the Maritime Province. As a tributary of the Dumangang, Sodumangang flows into the Posyet Bay. Nokdundo was an island separated from the Korean peninsula and the Maritime Province by the Dumangang and the Sodumangang respectively. Tributaries of the Dumangang have formed many alluvial islands at the mouth of Dumangang where the Dumangang meets with the East Sea. So, the possibility that Nokdundo was consisted of several islands can not be excluded.

근년의 북방외교 이후 눈에 띄게 동해 경게권이 대두되면서 급기야는 두만강 지역에 UN시를 건설하여 그 지역을 개발하자고 하는 매우 고무적인 계획까지 나오고 있다. 하지만 이런 일련의 변화 속에서 우리가 너무나 역사의식을 결여하고 있지 않나 하는 생각이 든다. 따라서 본고에서는 정부의 공식입장에 나타나지 않는 또 다른 부분에 대한 의견을 개진하고자 한다.

This research was conducted to analyze the actual condition of subject heading related to Korean border shown in the subject headings of 7 countries: United States, France, Germany, Spain, Russia, China, and Japan. The results are as follows. To begin with, Korean border-related records in most other national libraries are in extremely poor conditions except for some countries like United States. Amnokgang and Dumangang-related records did not search at all in the France. Yellow Sea, Dumangang, and Baekdusan-related records did not search at all in the Spain. Second, even Dokdo we have effective control, the geographical name 'Korea' is not marked with catalog records except the United States and France. The Germany is displayed with the geographical name of 'Korea' and 'Japan'. Third, the East Sea(Donghae) already is marked with 'Sea of Japan' in most of the national library catalogs, and Yellow Sea(Huanghai) is marked with 'Yellow Sea'. Fourth, Amnokgang and Dumangang is marked with Chinese pronunciation in most in most of the national library. Fifth, Baekdusan is marked with Korean pronunciation in most countries. However the United States showed in 'Baekdu Mountain' and 'Changbai Mountain' discrimination. In the case of the Germany, 'Changbai Mountain' are marked with variant access point of 'Baekdusan'.

This study is to suggest landform and environmental problems of border region of N. Korea and China by analyzing results of field work for the Dumangang and the Amnokgang from year 2000 up to year 2016. By the social system in North korea, access of study material is possible with satellite image and published statistical data, but impossible direct data collection. We gathered field work data on landform and environment in border Region of N. Korea and China. Before field survey, we analysed geometrical landform and geology using DEM and digital geology map. We analyzed landform and environmental problems occurring in upper, midstream, and downstream region of the Dumangang and the Amnokgang using field work data. Resultingly, this study will be expected to support as basic data for resonable management on natural resources and empirical research activities on North Korea.

This study was conducted to analyze the characteristics of records related to Korea shown in the cataloging records of national libraries of the main 12 developing countries in Europe and South America. The results are as follows. To begin with, Korea-related records in most national libraries are very poor and under 0.01% of the library. Second, Korean materials usually write Korean in Roman characters except for National Library of Armenia, but there are not marked with the original Korean language and unfeasible Hangeul search. Third, on investigation of the subject distribution in sub criteria of Korea-related records, subject related to history, politics, and economy is largely shown in the highest rate. Fifth, among the Korea-related subject heading, Taekwondo is marked with distinction from Karate in most libraries except for National Library of Argentina. Dokdo is marked with the geographical name of 'Korea' in 8 national libraries and East Sea (Donghae) already is marked with 'Sea of Japan' in 7 national libraries. Amnokgang, Dumangang, and Baekdusan-related records did not search at all in most national libraries.

Products of the eruption of Mt. Baekdusan are identified as volcanic materials at the estuaries of the Songhuagang river to north, the Dumangang river to east and the Amnokgang river to west. More speficially, pyroclastic flows, lahars and volcanic floods can affect an area of 400km in radius, centering around Lake Cheonji caldera. However, unlike the millenium eruption, the flow situation has been changed. Because multi-purpose dams and reserviors with a combined pondage of mora than 2 billion tons of water have been built in the rivers of which sources are originated from Lake Cheonji caldera. In addition, the flow of fluids expected to take place when the volcano has erupted is thought to be affected by artificial constructions in both direct and indirect ways. This study calculates the direction of fluids flow by using numerical analyses of pyroclastic flows, lahars and volcanic floods that can occur when the volcano of Mt. Baekdusan has erupted. We also estimate the scope of damages by pyroclastic flows, lahars, volcanic flooding caused by the pondage of the dams and water storages in and around Mt. Baekdusan. Pyroclastic flows transported over the steep slopes at the early times of eruptions move over the mountain slopes, affecting airplanes, and lahars due to leaks of Lake Cheonji could reach as far as major rivers and streams near Mt. Baekdusan. Unlike historical accounts, volcanic flood is expected to be limited in its scope of influence to reservoirs bigger than Lake Cheonji in pondage.

This study compares and analyzes the numbers and characteristics of Korea-related subjects included in the 2008 Japanese edition of the National Diet Library Subject Headings (NDLSH) and the $2^{nd}$ edition of the Chinese Classified Thesaurus(CCT). The analysis results show that 258 subjects, approximately twice as many as 137 subjects in CCT, were found in NDLSH. There are more pure subjects that exclude the references in CCT than in NDLSH. On the other hand, much more subjects are found in NDLSH in the event that personal names, corporate headings, and subjects combined with detailed headings are included. Meanwhile, more subjects are relatively engaged in the fields of politics, diplomacy, and military in CCT because CCT is characterized by socialism and by being a pro-North Korea. Moreover, the considerable numbers of subjects reflecting North Korea's viewpoint are included in CCT. NDLSH changed only recently the names of both South and North Korea into the "Republic of Korea" and the "Democratic People's Republic of Korea", respectively. On the other hand, CCT more frequently uses "Joseon" than "Korea", and the distinction between the names is unclear. CCT thoroughly supports the stance of the developed country, directly involved in the disputable subjects between two countries such as "Dokdo", "the East Sea", "Dumangang", and "Baekdusan". Both heading lists consider "Balhae" as part of Chinese history in CCT, which has ignored the position of Korea.

This study was conducted to analyze the characteristics of records related to Korea shown in the cataloging records of national libraries of the main 10 developing countries in Asia and Africa. The results are as follows. To begin with, Korea-related records in most national libraries are very poor and under 0.1% of the library. Except for National Library of Viet Nam, the figure is under 3,000 volumes and generally 2 times less than Japan related records. Second, except for National Library of Iran and Viet Nam most national libraries romanize Korean materials, there are not marked with the original Korean language and unfeasible Hangeul search. Third, on investigation of the subject distribution in sub criteria of Korea-related records, subject related to history and economy is largely shown in the highest rate. Fifth, among the Korea-related subject heading, Taekwondo is marked with distinction from Karate in most libraries except for 7 national libraries. Dokdo is marked with the geographical name of 'Korea' in 7 national libraries and East Sea (Donghae) already is marked with 'Japan, Sea of' in 7 national libraries. Amnokgang, Dumangang, and Baekdusan-related records did not search at all in most national libraries.
