This study attempted to simulate the flood discharge in the Duman River basin containing Hoeryong City and Musan County of North Korea where were damaged from Typhoon Lionrock on August, 2016. For hydrological modelling remotely sensed datasets were used to estimate watershed properties and hydrologic factors because the basin is ungauged where hydrological observation is not exist or sparse. For validation we applied our methodology and datasets to the Soyanggang Dam basin. It has not only similar shape factor and compactness ratio to those of the target basin but also accurate, adequate, and abundant measurements. The results showed that the flood discharge from Typhoon Lionrock corresponded to three to five years design floods in the Duman River basin. This indicate that the Duman River basin has a high risk of flood in the near future. Finally this study demonstrated that remotely sensed data and geographic information could be utilized to simulate flood discharge in an ungauged watershed.

In this paper, the relationship between energy consumption in the logistics industry and economic growth of Tumen River region from 1995 to 2014 is empirically analyzed by using the EKC model theory. The results show that there is a turning point in the Kuznets curve of carbon emission in TumenRiverregion. And it has the characteristic sof "invertedU" curve, which conforms to the environmental Kuznets curve hypothesis. Meanwhile it is stil lintherisingstage. According to the analysis results, it is proposed to set up the concept of low carbon logistics, optimize the energy structure, strengthen the information construction, and establish low-carbon development mechanism and so on.

In this article I try to investigate fifteen place names presented in the area of Baekdu mountain and Duman river of "Daedongnyeojido". The aims of the investigation are to clear Jeongho Kim's understanding on the national boundary implicated in the map, to search the etymology of the place names, and to analyze the place names miswritten. Through the investigation it will be suggested that the map presents the idea of 'Tomun river = Duman river = Bungye river', and recognizes 'Abrok river-Jeonggyebi-Duman river' as the landmarks of the boundary between Joseon(Korea) and Qing(China). Through the etymological analysis of the place names it will be suggested that some place names(Bundonggang, Geongatoi, Sihuasan, Geolodong and Daedong) originated from Nuzhen(Manchurian), the other place names(Gulsan and Guambong) originated from Korean. The location of the place names will be suggested also.

This research aims to analyze Baekdu mountain are with it's the east flowing streams which are the issues on the old maps. Also, it will analyze the eastern flows, Tomoon river; Boongye river; Dooman river, from Baekdu mountain which have been the border settlement issues since Josun dynasty. Also, it will analyze the north-eastern flows, Heukryong river; Songhwa river; Sockpyung river; Tomoon river; Boongye river; Dooman river, from Baekdu mountain which have been the border settlement issues since Josun dynasty. The mainly issued Baekdu mountain's north-eastern flows can be classified into six different flows by the classifications, it proves that there are various Baekdu mountain north-eastern flows on the old maps. the two streams theory of Tomoon and Doman river explains the perspective of the northern expansion, and the one stream theory expresses it by stating Boongye and Sockpyung river as the same one. However, in the case of the meaning of Boongye river is Haeran river on the middle of one stream theory map, there is no region expanding perspective but the same border perspective that Korean peninsula and China match. Boongye river is expressed into four different meanings. (1) It is the same river with Sockpyung and shows the regional expanding perception. (2) It is the same river with Tomoon and the down stream of Tomoon river.(3) It expresses the current name, Haeran river. (4) It simply means the river shows the boundary.

The Tumen River basin is relatively small(${\approx}33,000km^2$), it has many potential conflicts between the riparian countries. Especially, until recently, it could have not drawn the socio-potitical attention from its central governments because of the geopolitical unique characteristics as edges of mainlands. since 1990's the various plans have been suggested for resolving the problems in this area as an international attention from, e.g UNDP, began to be given. However, the international cooperative structure has not been established in systematic way which has paramount importance. In the research, based on the problems identified in the previous paper, the necessities for independent unit, so called 'Tumen River Watershed Management Commission' were suggested for holistic and hierarchical resolution in accordance with integrated management and international river based on 'limited territory sovereignty' which is a general principle in international river management. For this purposes, hierarchical problem solving approach which consists of 3 phases were developed. They include major objectives and behavioral guidelines for achieving equity between riparian countries based on international cooperation and integrated watershed management as fundamental concept. In conclusion, rational plan for future water use, management and primary framework of Tumen River for international cooperation were composed and strategic approach for the North-East Asian community foundation was suggested.

This study was conducted by China along with the Tumen River, which cuts between of North Korea and China. As a result 92 family, 287 genera, 470 species, 57 variety 4 formas, total 531 taxa of vascular plants were identified. The surveyed area was include the region that had various vegetation such as upper swampy land, seashore dune, a river, a high mountain grassy plain, deciduous tree zone and evergreen coniferous forest zone. The specfic plants which is protected by The Natural Environmental Preseration Act appeared to 6 taxa, and rare and endangered plants conserved by Forestry Administration were found 21 taxa in these areas. Among them Lilium cernum, Jeffersonia dubia, Acanthopanax senticosus could be regarded as very important one for chinese medicine. Picea koraiensis, Larix gmelini var. principis-ruprechtii, Populus koreana, Betula fusenensis, Ulmus pumila, Ledum palustre var. diversipilosum, Rhododendron parvifolium, Vaccinium uliginosum, Astragalus membranaceus, Aquilegia flabellata var. pumila, Carex gotoi, Carex capricornis etc. are not distributed in the South Korea.

This geographical study is to identify the reality of Nokdun island which was once settled and farmed by our ancestor, but currently the island is do facto under Russia's control. Various historical documents including old maps, current large scale maps and satellite images besides field work were used for full analysis. According to historical records, up until Chosun Dynasty, Nokdun island in the lower Tuman river was one of the frontier fortified base crossed the river for the northern defense as well as seasonal farming for the farmer of Kyounghung border area. Even though the island was unjustly lost to Russia by the Beijing Treaty in the late Chosun period, the whole area of Nokdun was occupied and farmed by sole Koreans until the deportation by Stalin was forcibly measured. In these days due to the change of Tumn river channel and new deposition by river it became very difficult to find the original shape of Nokdun island. However, through intensive field works based on historical records, the research team found out the existence of the old wet-dry fields, old rural farmhouse remnants, and small and medium size of millstones that are supporting the reality of the island. Especially, the team traced a mud fortress presumedly built in the early Chosun period. We believe it might allow to allocate the exact location of Nokdun island in near future.

한반도의 기후변화는 전 세계 평균보다도 빠르게 진행되고 있다. 최근 빈발하고 있는 태풍 및 극한 강우, 폭설과 한파, 온난화 현상 등이 그 예이다. 특히 북한지역은 오랜 식량난과 에너지난으로 산림생태계가 훼손되어 홍수 및 이수와 같은 기후변화 관련 자연재해에 매우 취약하다. 이렇게 예상되는 대규모 자연재해를 대비하고 기후변화에 효율적으로 대처하기 위해서는 체계적이고 과학적인 기상 및 기후 예측 정보의 활용이 매우 중요하다. 하지만 북한지역은 우리가 수문자료를 구하기가 힘들고, 직접 측정을 할 수 없으므로 수문자료의 수집에 한계가 있기 때문에 기후변화관련 수문연구에 한계점이 있다. 따라서 본 논문에서는 WMO에서 제공하고 있는 북한의 27개 기상관측소의 강수량, 기온자료와 기상청의 RCP8.5기후변화시나리오를 제공 받아 각 관측소별 미래 잠재증발산량을 산정하였다. 또한 lumped conceptual model인 WASMOD 모형을 이용하여 북한의 대표유역(금야강, 대동강, 두만강, 압록강, 예성강, 임진강, 장연남대천)에 적용하여 부족한 수문시계열자료를 산정하였다. 이렇게 산정된 북한의 미래 수문순환요소의 시계열자료를 이용하여 통계분석, 변화점분석, 유황분석등 시계열 분석 등을 통해 RCP8.5기후변화시나리오 기반의 기후변화가 북한지역의 수문순환과정에 미치는 영향을 분석하고, 이를 통해 유역규모의 수자원에 미치는 영향을 전망하였다.
