GIS와 RS를 이용한 토지피복 및 식생 분포의 시ㆍ공간적 변화 -평안북도 서부 지역을 중심으로-
이민부(Min-Boo Lee),김남신(Nam-Shin Kim),최한성(Han-Sung Choe),신근하(Keun-Ha Shin) 대한지리학회 2003 대한지리학회지 Vol.38 No.5
본 연구에서는 GIS 및 RS를 이용하여 평안북도 서부지역을 대상으로 1988년~2001년 사이의 토지피복과 식생 분포의 시·공간적 변화를 살펴보았다. 이를 위해, Landsat TM 및 ETM 영상을 사용하여, 기하 방사 보정 후, 감독 분류와 NDVI 분석을 실시하였다. 분석 결과, 평안북도 삭주, 대관, 구성, 의주 지역에서는 13년 동안 산림이 감소하고 시가지, 인간의 간섭에 의해 발생한 황무지, 범람과 사태 등의 자연적 요인에 의한 나대지 등이 증가한 것을 관찰하였다. 또한, DEM 분석을 통해 대부분 지역에서 고도가 높고 경사도가 큰 지역까지 시가지 개발 및 확장, 개간이 이루어지면서 더 많은 황무지가 발생하고, 비교적 높은 고도에서도 NDVI 값이 감소한 사실을 알 수 있었다. 이러한 변화는 지형적 특성을 고려하지 않은 채 이루어진 개발에 의한 것이며, 산사태 등의 자연재해 방지, 안정적인 식량공급 등을 위해 많은 연구 및 해결책 제시가 필요할 것으로 본다. This study deals with the spatio-temporal change of land cover and vegetation distribution between 1988 and 2001 using remote sensing images and GIS techniques in west area of Pyeongbuk Province, northwest Korea. Landsat TM and ETM images are geometrically and radiometrically corrected for the analysis of land cover and NDVI. Forested areas are decreased during 13 year from 1988 to 2001 in study area including Sakju, Daegwan, Guseong and Euiju of Pyeongbuk Province, because wasteland are increased by human impact and denuded land by landslide and flooding. DEM analysis presents that settlement and cropland are developed toward higher and steeper mountain slope, together with decrease NDVI values. these changes have resulted from unplanned increase of cropland without consideration of geomorphic condition. Therefore, more researches and reasonable policies are required to protect forest and cropland and stable food supply against natural hazard like landslide.

中國 延邊地域의 관광자원과 한국 단체 관광에 대한 고찰
최한성 한국 지리·환경 교육학회 1998 한국지리환경교육학회지 Vol.6 No.2
Since the diplomatic relationships between Korea and China are established, a number of Korean touristics and package tours to China are growing increasingly. Therefore it is needed to analyse this touristic phenomena and to estimate this trend, in order to exploit touristic resources and to develope new concepts in tourism. The purpose of this theses is to classify the touristic resources in Yenbyon and to analyse the Korean package tours of this area and to suggest improved touristic plans. The touristic resources for Korean visitors in Yenbyon could be classified into nature geographical group, ancient and medieval historical relic, anti-Japanese remains and present socioeconomic types. Natural touristic resources are mainly existed in Mt. Paekdusan and its circumference, which are made up volcanos and lav plateaus, where vertical distribution zones of vegetation are formed. Most of historical relic in Yenbyon take their rises from Balhae(Pohai)-Dynastie. The anti-japanese remains against military imperial colonialism are too potential resources for Korean. Yenbyon is located in border land between North-Korea, China and Russia. As the border land there are also attractive social and political touristic resources in example customs and gates between the nations. According to the analyse of package tour programmes Mt. Paekdusan and its circumferential areas are major tourist resorts and the others play auxiliary roles in Korean package tours. These Paekdusan tours are limited only within summer seasons because of the winter weather conditions. These tours provide simple programme, which consist of climbing the mountain and sighting the lake Chonji and water falls. It can be suggested that the programmes of these tours are needed to be diverse and to be arranged closely with other touristic resources in this region. Especially on the basis of natural environment in this region ecotourism will be practical and realizable idea. It is also thinkable to organize thema tours from various touristic resources, for instance historical tour, cultural tour, city tour or ecotour etc. For these purposes it is necessary to train guiders for more understanding of the region in particular about geography, history and the other related disciplines. The restriction of the summer season tours in the region will be tided over introducing winter sports and construction of sports facilities for foreign tourists. It is also desirable that the airport of Yenji will be raised from inner to the international status, so that air traffics between Seoul and Yenji will be directly connected and tourists can save costs and time.

최근 5 년간의 " Praxis Geographie " 를 통하여 본 독일의 지리과 수업에서의 Computer 와 Telekommunikation 의 이용에 대한 소고
최한성 서울대학교 지리교육과 1996 地理敎育論集 Vol.35 No.1
New educational changes are forecasted to come to Korea reflecting the wide use of computers and the utilization of telecommunication. It is necessary to discuss how the current trends in technology will effect geography courses in Korean schools. However, because geography courses are very sensitive to the requirements for the national entrance examination, it is difficult to predict the changes in courses in the future. Therefore, it is very useful to look outside of Korea and see how other countries have assimilated technology into course work. For this paper, Germany was selected as the subject country. This study involves a description of the computer, software and telecommunication utilization for geography courses in Germany. In order to understand the trend in Germany, the contents of the magazine $quot;Praxis Geography$quot; were reviewed. ($quot;Praxis Geography$quot; is a popular professional magazine for the teaching and study of geography in Germany.) A review of the magazine's contents for the last five years indicates that regional studies and systematic geography are strongly linked. A monthly theme about computer-software for geography courses was covered in volume 3/1995. In this volume, the spread and utilization of computers in German schools was discussed. Also included in this volume were a geography syllabus that integrated computers, software for geography classes, methods of networking, trends of teaching geography and some critical analysis of courses. In this paper a few software products which are popular for geography courses in Germany such as Wega, HIima, Hunger in Afrika, IDRISI, MOBIT, RUDI-RUHR, SimCity, were briefly introduced. According to the magazines it is necessary to promote the widespread use of computers in schools and to invest in the development of adequate software, in order to complete geogprahical courses in Germany; it is also very important to study the negative effects in rapidly changing the educational environment by introducing computers into geography courses.

康津 靑磁陶窯地에서 이용되는 素地의 鑛物特性에 관한 硏究
崔漢成 한국 지리·환경 교육학회 1995 한국지리환경교육학회지 Vol.3 No.1
Gangjin region is well-known to the kiln sites of the celadons of Koryo-dynasty. Recent there are the try to reproduce celadons similar to those of Koryo-Dynasty. At first it is necessary to obtain the mineralogical information about the raw material of the celadon bodines for the produce processing. for these purposes the clay mineral identifications on the raw materials for celadon bodies from Gangjin-kiln site are carried out by the method of X-ray diffraction. Major clay minerals of raw materials for the celadon bodies are illite, kaolinite and 7 A halloysite. These materials bodies were transportied from weathered parent rocks.

한국의 산간 분지는 일반적으로 침식 분지로 알려져 있다. 최근 이러한 침식 분지 내에 남겨진 퇴적물에 대한 분석이 이루어지고 있다. 거창 분지는 덕유가야산지에 발달되어 있는데, 분지 내의 구릉과 평탄지 말단부에 퇴적물이 나타난다. 본 연구에서는 이러한 퇴적물을 분석하여 개략의 퇴적물 공급지와 이동 거리를 추정하고자 하였다. 이를 위하여 거창 분지에 잔존하고 있는 퇴적물 노두를 기술하고, 이들 퇴적물의 입경 분석을 행하였다. 또한 이 퇴적물 중에서 모래 층과 모래 입자에 대한 형태와 표면 상태에 대한 현미경 관찰을 하였다. 이러한 모래 입자에 대한 분석에는 중급 모래(200~630㎛)를 이용하였다. 석영의 모래 입자는 다른 광물에 비하여 상대적으로 풍화와 침식에 강하기 때문에 대략의 풍화 양상, 운반 과정과 이동 거리 등을 추론하여 볼 수 있다고 여겨지기 때문이었다. 거창 분지에 나타나는 노두 중에서 4개를 선택하여 퇴적물을 분석한 결과 점토를 최고 58%까지 함유한 층들이 나타나고 있으며, 모래 분석을 한 결과는 대부분의 모래 입자들은 원마되지 않은 각력의 상태로 있으며, 광택이 나는 입자로 존재한다. 간혹 표면에 미세한 오목한 모양을 한 것도 있다. 종합하여 보면 모래의 공급원은 가까운 곳의 기반암 풍화층으로 사료되며, 이동 거리는 매우 짧았던 것으로 추정된다.
