  • 특정 지역에 대한 공간 분석을 하기 위해서는 많은 요소들을 고려해야 한다. 예를 들어 시설물을 설치한다거나 경과지역 내에서의 공간 분석이 필요할 경우, 법적 제한 요건 및 지형적 특성에 따라 공간 분석 패턴들을 다양하게 생성할 수 있기 때문이다. 이에 올바른 분석 기법의 선정이나 정확한 자료들의 수집은 필수적이라 할 수 있겠다. 따라서 본 연구에서는 해당 지역 내에서의 경과지 선정 기준을 알아보고 그에 따른 저항치와 경중률을 계산하여 각각의 지형적 요소에 적용시켜 분석을 실시하였다. 그리고 분석 시에는 Corridor와 같은 GIS 공간분석기법을 이용하여 해당 지역 내의 송전 철탑 설치를 위한 최적 경과지와 최적 경로를 선정하였다.

  • Monthly runoff was estimated using TOPMODEL which simulates ground water movement as well as surface runoff in the area of catchment. SAYUN dam which is being operated by Korea Water Resources Corporation was selected for the study, and the topographic factors of the watershed were analyzed using 1/5,000 digital map and GIS software(Arc/Info). The comparison shows good agreement between observed monthly runoff and the computation results simulated by using TOPMODEL. The catchment area of SAYUN dam was modeled by using various grid sizes in order to check the sensitivity of grid size, and the grid size of 180m was found most proper among 6 different sizes. TOPMODEL was also found superior to the existing monthly runoff models such as Kajiyama, KRIHS and Tank. Because the model requires limited number of parameters and considers topographic aspects, it is reckoned to be very useful for practical use.

  • Geophysical survey were investigated in the offshore around East Sea Research Institute, Korea Ocean Research and Development Institute (Jukbyeon-myun, Uljin-gu, Gyeongsangbuk-do, Korea). The surveys were conducted aboard the R/V Jangmok in 2008 using a hull-mounted EM 3002 multi-beam echosounder. Precise bathymetry and seabed images were obtained using multi-beam and thicknesses of sedimentary layer were found through seismic survey. Submarine topography deepens parallel to the coastline to -60 m and rock mass distributed in the southeast of study area. By finding the thickness of sedimentary layer through seismic survey, a sedimentary thickness on the study area was established. Futhermore, monitoring data of bathymetry, substructure and sedimentary environment will be secured through successive geophysical investigation.

  • 최근들어 우리나라 하천에는 많은 식생이 발생하고 있다. 과거 댐에 의한 유황 조절효과로 댐 하류에 식생이 과도하게 발생하는 사례는 많았지만 최근 발생하는 식생은 댐의 유무에 직접 관련되지 않고 있다. 또한 하천의 규모나 위치 등과도 관계없이 거의 모든 하천에서 대규모로 발생하고 있다. 이와같은 식생은 하천의 통수능을 줄여서 홍수위를 상승시키는 역할과 더불어 하천의 육역화를 일으켜서 하천의 모습을 상실하게 하는 역할도 한다. 일본 등의 경우에도 하천에 과도하게 발생하고 있는 식생으로 인해 하천관리의 문제로 대두되고 있다. 해외의 경우 하천내 식생 발생 메카니즘에 대한 연구가 다양하게 진행되고 있다. 유황의 변화, 하천 지형의 변화, 영양물질의 변화 등으로 인해 발생하는 식생의 현황과 원인을 규명하고 있다. 더불어 식생의 지속적인 제거를 위해서 기계적인 방법, 화학적인 방법, 수문학적 방법 등의 개발과 적용에 대해서도 다양한 연구가 이루어지고 있다. 본 연구에서는 국내 중소하천에서 발생하고 있는 식생의 현황을 파악하고 하천내 지형조건과 식생 발생의 연결 고리를 분석하였다. 최근 10년 이내 많은 중소하천에서 하천내 많은 면적을 식생이 차지하게 되었는데 이와 같은 현상의 원인은 크게 두 가지로 분석되었다. 첫 번째는 유황의 변화이다. 최근들어 대규모의 홍수발생 빈도가 급격하게 줄어들어 식생이 발생할 수 있는 조건이 크게 확대된 것으로 파악되었다. 홍수 발생 감소로 봄이나 여름철에 하천내 흐름이 발생하여 씨앗이나 어린 식생이 쓸려 내려갈 기회가 감소되었다. 두 번째는 과거 조성된 복단면 형상으로 인해 고수부지의 경우 흐름이 발생할 기회가 현저하게 감소하여 고수부지가 육역화되는 현상이 발생하고 있다. 특히 이 두가지 요인이 중첩되면서 하천내 식생의 증가는 급속하게 발생되고 있는 것으로 분석되었다. 본 연구에서는 하천 단면 지형의 연도별 변화, 수위의 변화, 식생의 변화를 연계하여 식생의 발생 원인을 물리적으로 규명하였다. 본 연구의 결과를 활용하면 하천에서 발생하고 있는 과도한 식생의 원인을 추정할 수 있고 이를 해소하기 위한 대안으로 하천 단면의 관리 방안을 검토할 수 있다. 기후변화 등의 외부적인 요인으로 인해 발생하는 유황의 변화가 과거와는 다르게 발생하고 있는 점을 감안하면 하천내 식생의 발생 현황 및 제거 방안을 도출하는 것은 시급한 과제라고 판단된다.

  • Space exploration is at the forefront of human scientific endeavors, and planetary exploration rovers play a critical role in studying planetary surfaces. Rover performance is especially vital for safely navigating steep terrain and delicate landscapes found on planets like Mars and the Moon. This paper offers a comprehensive overview of a landing testbed designed to simulate challenging extraterrestrial terrain and loose regolith. The paper briefly outlines lunar crater region topographical features and highlights the importance of these simulations in rover testing. It then explores previous landing testbed developments and describes the design process for a landing testbed to be installed in the dirty thermal vacuum chamber at the Korea Institute of Civil Engineering and Building Technology. Once realized, this proposed landing testbed will enable precise evaluations of rover mobility and exploration capabilities under lunar-like conditions, including high vacuum and extreme temperatures.

  • In order to plunder the Korean Peninsula in earnest, 'Modern Age Korea Topographical Map' of reduced 1:50,000 scale was manufactured within the period of 5 years from 1914 to 1918 through Japanese government-general of Joseson. This map includes all the data representing the life model of Korean Peninsula in the period of the End of Korean Empire, before the modern public construction works had started to seriously develop. This study analyzes the land use change after embedding the coordinates to the image of Modern Age Korea Topographical Map, which includes the scenery of 1910, and then overlaying it with the contemporary map in GIS environment. The results of presented research showed that before modern civil construction works started, the farmlands had lost their competitiveness because of difficult for development hilly areas and frequent floods, the river sites being abandoned and industrial structure change, and were developed into modern city area.

  • The Korean peninsular is a typical mountainous terrain country which has 75% of mountains with having featuring of east-high west-low and north-high south-low type. Though the physiographic feature is not changed, the future operational environment has been frequently changed through artificial transformation by people living in the city. While Korea has been changed continuously since 2000, 90% of Korean territory has been urbanized and the majority of people live in the city. In particular, in the case of combat in urban area, there might be lots of limitations because of confusing with millions of people and complex buildings. The combat commanders should make an effort to overcome such difficulties through detailed IPB(Intelligence preparation in the battlefield) considering various situation before planning for major operations. They should change warfighting concept and paradigm. This paper finds the normal characteristics of urban operation and physical traits of the Korean peninsular. As the urbanization has been accelerating in Korea, practical implications about how to prepare the urban operation are discussed.

  • The scientific, economical and industrial values of the Moon have been increased, as massive ice-water and rare resource were founded from the lunar exploration missions. Korea and other major space agencies in the world are competitively developing the ISRU (In Situ Resource Utilization) technology to secure future lunar resource as well as to construct the lunar base. To prepare for the lunar construction, it is essential to develop the rover based construction spatial information technology to provide a decision-making aided information during the lunar construction process. Thus, this research presented the construction spatial information technology based upon rover's camera system. Specifically, the conceptual design of rover based camera system was designed for acquisition of a rover's navigation image, and lunar terrain and construction images around the rover. The reference architecture of the rover operation system was designed for computation of the lunar construction spatial information. Also, rover's localization and terrain reconstruction methods were introduced considering the characteristics of lunar surface environments. It is necessary to test and validate the conceptual design of the construction spatial information technology. Thus, in the future study, the developed rover and rover operation system will be applied to the lunar terrestrial analogue site for further improvements.

  • The UNESCO`s earth science division has developed the geoparks program to recognize earth scientific heritage sites worldwide. To respond to this movement, I suggest Byeonsanbando National Park (BNP) as the first geopark in Korea and provide, at the same time, a line of evidence supporting the designation of geopark. BNP has the best qualifications with geological, geomorphological, ecological, and cultural resources. In Chaeseokgang and Jeokbyukgang, there are many geological and geomorphological resources attracting the scientific importance. In addition, BNP has a total of 844 species of wild plants and 550 species of wild animals. Cultural properties abound in BNP, including Koryo bronze bell of Naesosa and Taeungjon hall of Kaeamsa. To be designated a geopark by UNESCO, a management plan of geotourism will be required in addition to the geological, geomorphological, ecological and cultural resources, which should be prepared by the Korea National Parks Service and related local government authority. If the above-mentioned conditions are met completely, Korea would enter the global network of geoparks for the first time.
