  • The Democratic People's Republic of Korea, or the DPRK, is one of the poorest country in world facing chronic economic, energy and food security issues. Prolonged improper management of economic and natural resources has led to extreme poverty, malnutrition and critically vulnerability to nature's forces. Presistent deforestation and forest degradation in the DPRK has national and global consequences which has attracted attention from international community, whose offering financial and technical assistance for targeted interventions. Through REDD+ programs, the DPRK has the opportunity to establish its credentials as a responsible nation while improving the quality of life of its population. This study offers an enabling context under which suitable climate change action related to forestry can be identified and implemented in the DPRK.

  • China is one of the countries in which flood occurs most frequently in the world and with the current economic growth; flood disaster causes more and more economic losses. Chinese government pays more attention to flood monitoring and assessment by space technology. Since1983, NOAA(AVHRR), Landsat-TM, LANDSAT-ETM+, JERS-1, SPOT, ERS-2, Radarsat-1, CBERS-1, Envisat have been used for flood monitoring and assessment. Due to the bad weather conditions during flood, microwave remote sensing is the major tools for flood monitoring. Envisat is one of the best satellite with powerful SAR. Its application for flood monitoring has been studied and its near real time(NRT) application can be realized on the basis of real-time delivery of image. During the 2005, 2006 and 2007 flood seasons, over the 31 NRT flood monitoring based on Envisat, had been carried out in Yangtze, Songua, Huaihe, pearl river basin. The result shows that Envisat SAR is very useful data source for flood disaster monitoring and assessment.

  • Ba Ria - Vung Tau province in Southern Vietnam is one of the fastest economic growing areas in the country, characterized by the rapid port and industrial development along the Thi Vai river. The socio-economic situation of the area has generally been improved; however, its part of the local inhabitants has not gained benefits from the changes. 35 surface water samples and 25 sediment samples were analysed with the interpretation of the SPOT images for 1995 and 2005. The data showed that rapid port and industrial development have resulted in significant losses of mangroves and agriculture land. The surface water was seriously polluted, particularly in terms of organic materials and suspended solids. It contained high and increasing oil concentrations. The river sediment was saline and slightly alkaline. It was heavily reduced, organic-rich, and contaminated with oil and heavy metals (Cu, Pb, and Cr).

  • This paper presents results of interpretaton of gravity data by iterative nonlinear inversion methods. The gravity data are obtained by a theoretical formula for two-dimensional 2-layer structure. Depths to the basement of the structure are determined from the gravity data by four interative inversion methods. The four inversion methods used here are the Gradient, Gauss-Newton, Newton-Raphson, and Full Newton methods. Inversions are performed by using different initial guesses of depth for the over-determined, even-determined, and under-determined cases. This study shows that the depth can be determined well by all of the methods and most efficiently by the Newton-Raphson method.

  • The purpose of this study were to understand the resident's attitudes toward Ulleung Island and to identify the residents' perception of recreation and the influence of socioeconomic characteristics on their response. In summer of 1999, 222 questioners were obtained from a convenience sample of households within Ulleung Island. The residents perceived both positive and negative environ-recreation and economic impacts, most of the residents supported additional recreation development and disagreed to limit the number of visitors. Their perception of recreation impacts were varied with age, education level, economic dependency on recreation place of residence, and length of residence.

  • Uranium resources of Mongolia are generally confined to sediments deposited during Jurassic to Cretaceous volcanism. Territory of Mongolian uranium deposits is divided into four districts as follows; Mongol-Priargun, Gobi-Tamtsag, Hentii-Dauer, North-Mongolian. Potential uranium deposits were discovered by Airborne Gamma ray Spectrometric Survey(AGSM). One of them, Haraat deposit, which was interested to us, has been under detailed survey for exploitation by one of American companies, Concord company. The Erdes uranium mine is partly operated by about hundred Russian staffs at the open pit, while underground mining facilities such as the main hoist are almost closed. Ore minerals of the Erdes Mine are coffinite and pitchblende. Uranium content in ore ranges from 0.06% to 1%, averaging 0.2%. Ore reserves of uranium ore in the Dornod deposit including the Erdes Mine accounts 29,000 ton. It is reported that Uranium resources of Mongolia are 1,471,000 ton.

  • 천연자원 및 물질순환은 자원채광, 운반, 처리, 활용, 회수 및 폐기 등과 관련된 모든 인간의 활동을 포함한다. 지속가능한 물질 관리는 물질순환을 통해 경제적 매개체에 맞추어진 통합된 정책수단이며 경제적으로 효율적이고 환경적으로 효과적인 물질의 사용을 위한 것이다. 산업광물, 금속광물 및 화석연료의 물질흐름은 회수, 처리, 소비 및 최종 폐기와 관련된 환경적 압력 때문에 지금껏 환경정책의 주된 영역이었다. OECD의 물질흐름분석연구는 회원국의 경제운용에서 물질자원의 중요성에 대한 이해의 폭을 넓혀 국가별국가간 천연자원 및 물질흐름에 대한 정량적이고 분석적인 지식기반을 증진하는 것이다. 현재 EU에서는 물질흐름계정이 몇몇 회원국에서 공식통계로 활용되고 있다. 주로 물질흐름분석은 물질흐름계정으로부터 정보를 활용하여 물질사용의 효율성을 평가하는 가치화기법으로서 기존의 경제모니터링시스템에서 파악되지 않는 천연자원 등의 폐기를 인지하는데 활용된다. 물질흐름분석에서 자원사용과 효율성은 장기간의 지속가능성 및 환경정책을 위한 중요한 주제로 떠오르고 있는 것이다.

  • The Lake (Victoria) zone of Tanzania, which has the least forest resources in the country, is a potential economic growth zone in the country. Therefore, this study analyses the impact of implemented forest policies on the status of forest resources in the area, given the unique features. The study identifies the status of forested lands in the area, and then fits binary logistic regression to identify the impact of policies related elements (i.e. type of forest, type of management) on the status; forest area and location (region) are used as control variables. Results show that 63% of the forested land in the area is destructed; main activities being agriculture, residential, firewood, and charcoal burning activities. Logistic results showed natural forests, forests located in Geita region, forests managed by municipal councils are more likely to be destructed; while plantation forests, forests located in Kagera region, privately managed forests are less likely to be destructed. Thus, the study concludes that policies and measures are not enough for the preservation of forest resources in the area; some of the economic activities in the area are occurring at the expenses of the forests; hence recommend more sustainable development plans and incorporating different crossing cutting sectors in the policies.

  • This thesis is the result of the study about 'How we should develop the human resources program to gain human strength in the strategic environment of the future?' Once again, regional stability is interdependent with economic stability, political stability, and military stability of all the factors in the region. History shows that if a militarily capable regime lacks economic resources, then there is political pressure on the regime to use their military to acquire needed resources. The purpose of this study is to find the way that how to gain excellent human resources now and in the future. Military man power should be strong whenever. The Ministry of National Defense has "Reform Military Structure Plan". The focus of this Plan is Korean military strategy in the situation of the confrontation between South and North Korea and in the situation of the international relationship and the way of constructing the military strength for the future. To study these subjects, I reviewed the theories of "Acquisition Program of Human Strength" were developed and assessed the future strategic environment of the Korean Peninsula. From these studies, I suggest that The Ministry of National Defense should pursue preparing for the future military strategy and military structure. we should be skillful in supplementing the Human Strength. We should study about Military Revolution Plan and Human Strength structure for the future.
