  • This study was carried out to manufacture wooden vessels by small diameter wood and wasted wood of Castanea crenata Sieb. et Zucc, which has been largely planted in southern area. We made spice set, tea box set, cookie vessel set, bowl set and accessory set. With the development of edged tools, the human species has been able to fashion wood to change and enhance its environment - one only has to look at the history of all cultures to see examples of wooden artifacts and structures. Even with the development of synthetic materials and the progress of automated, mechanized production of wood and wood products, the raw material is still processed by traditional methods to meet a never-ending demand for products made from this most desirable natural material. Chestnut wood has high added value and natural color grain and is very useful for wooden vessel. Thinned low grade trees can be used to produce wooden vessel. Therefore this result can promote thinning and produce good forestation.

  • When harmonized with modem design, the Korean traditional lacquered woodenware with a history of about two thousand years has the potential to appeal to the global sense of industrial craftsmanship as it is superior to any in terms of material used and is very friendly environmentally. To maximize this potential, however, it is necessary to develop a firm infrastructure for the supply of lacquer, including the forestation for the lacquer wood, the production of lacquer, the improvement of refining skills, and the development of better paints. Also ways must be found to induce the craftsmanship at the turning lathe to be elevated to a major independent industrial craft. Only then the mass-produced lacquered woodenware for everyday use and as tourist goods, showing the best merits of the Korean lathing technique, will be displayed and accepted with a new appreciation.

  • 국가 공간정보 중 지형의 형태를 나타내기 위해 수치표고모형(DEM)을 사용한다. 수치표고모형을 생성하기 위한 다양한 방법 중 항공 LiDAR를 활용한 방법은 지형의 변화에 신속하게 자료를 획득할 수 있고, 사진측량기법에 비해 기상조건에 따른 제약을 덜 받는다. 이러한 항공 LiDAR는 최근 국가공간정보의 제작에 다양하게 활용되기 시작하였으나, 다양한 식생이 우거진 한반도의 산림지역에서 일반적으로 평가되고 있는 항공 LiDAR 측량의 정확도가 얻어지는 지에 대한 연구는 아직 이루어지고 있지 않다. 본 논문에서는 다양한 식생이 존재하는 산림지역을 연구대상지역으로 선택하여 수목의 특성에 따라 항공 LiDAR 자료의 정확도가 어떻게 다른지 평가하고자 하였다. 연구대상지역은 낮은 식생이 존재하는 나대지를 포함하고 있는 지역과 이 나대지의 경계부분과 인접하고 있는 다양한 수목이 존재하는 산림지역을 선정하였다. 선정된 지역에 대하여 대상지역에 고르게 분포하도록 검사점을 선점하고 GPS 측량을 실시하였다. 이렇게 측량된 검사점과 항공 LiDAR 자료와의 비교를 통하여 정확도를 평가하였다. 정확도 평가 결과, 활엽수 지역에서는 상당히 큰 오차가 발생할 수 있기 때문에 항공 LiDAR 측량에서도 촬영시기를 낙엽이 떨어진 이후로 하여야 함을 알 수 있었다.

  • This study was designed to present a river model with an aim at restoring the ecosystem and improving the landscape along the urban rivers on the basin of the Namhan river, a core life channel for the National Capital region. The revelation of botanical status, transition trend and correlation of plants might lead to providing the urban river restoration projects and ecological river formation projects with basic data for a model of ideal aquatic ecology and landscape. The outcomes of this study could be summed up as follows: 1. Communities of Juglans mandshurica, Cornus controversa and Fraxinus mandshurica constitute the main portion of flora at or around uppermost branch streams of the River Namhanis harbored mainly in and around small brooks 2. Typical terrestrial forest communities formed around the River Namhan are composed mainly of Larix leptolepis, Pinus rigida, planned forestation of Pinus koraiensis, Quercus acutissima, Quercus variabilis and Pinus densiflora. 3. The analysis into terrestrial environment of plant communities showed a high content of $P_2O_5$, typical communities found in the artificially disturbed land Finally, it seems also desirable to continue to make every exertion to explore the relationship between fluvial and terrestrial ecologies with a purport of building up a model of natural streams in urban area based on the surveyed factors for plant life, forest communities, soil and landscape and, moreover, on the forecasting for overall influences derived from the relation upon the ecosystem.

  • Recently, As a part of urban forestation, the introductions of green roofs into public projects has been actively driven. Supported by this policy, the sizes of domestic green roof related markets have been rapidly expanding and many types of root barrier materials developed in Korea or abroad are being commercially distributed. In this study, root barrier tests were conducted over two years with nine types of sheet type waterproof materials that are the most commonly used as root barrier layers in green roof systems. The test conditions prepared considered the climates, natural features and vegetation in Korea and the results and related root barrier performance were verified. From the results of this study, the necessity to improve the joint part of root barrier sheets and forming methods has been identified and a measure to improve domestic root barrier testing methods was proposed.

  • Planting pine trees on the coastal dunes has been carried out along the East coast as well as West coast of South Korea. Although the artificial forestation has been regarded as a good policy that help to protect the coastal area from natural disasters, but its real effect to the landscapes is still unknown. In this study, we have installed a monitoring site with an automated weather station to study requirements for dune formation and its environmental changes in Osan beach, Yangyang-Gun, Gangwon Province. We analyzed the meteorological data collected from 2010 to 2019 and vegetational changes in the study area. As a result, the wind speed is decreased by around 30% and the pine-covered area is increased by around 300m2 after planting Japanese Black Pine in 2015. At present, it seems that the eolian transport of sand particle is minimal, because the dominant winds are the westerly winds which is not landward but seaward, and because the surface roughness length is about 0.5m which is similar to that in the deciduous forest.

  • The geomorphological changes of an unvegetated part of the Okjukdong coastal dune were analyzed between 2008 and 2018. Its natural landscape has been destroyed after artificial forestation, but there is no quantitative evidence on these changes. In this study, we measured the unvegetated area using a total station and a network RTK-GPS in 2008, 2014, and 2018. Using Krging method for the three point data sets, we constructed digital elevation models (DEMs) and analyzed topographic changes between the three years. The results showed that the sand of the study area decreased in volume from 2008 to 2014, because sand supply from the nearby beach was blocked by coastal forests. The sand volume temporarily increased from 2014 to 2018, because of the dune nourishment conducted in 2017. It seems that the upper part of the sand dune has shrunk, but the sand at the bottom has increased over the last decade.

  • The purpose of this study was to research the change of the forest in Myungseo-lee Sanchuk-myun, Chungju where most of the area managed the Swidden Agriculture(Shifting cultivation). The mountainous district should be used and developed the multi-purposing source among the agricultural field, grassland, forest, a recreational area, and an industrial site, and should be presupposed the establishment of synthetic and efficient change system. This study began to pay attention to observe the peculiarity of Swidden Agricultural area in terms of forest aspects and to broaden the outlook of Swidden Agriculture. In the status of Myungseo-lee, prior to the Project to Rehabilitate the Illegal Swidden, from 1973 to 1976, the private forest gets 110.9ha (23ha for Seodae-village, 26ha for Dooduk-village, 6ha for Myungdol-village, 41ha for Chungam-village, 14.9ha for Pangdae-village). In Myungseo-lee. millet and corn were harvested, and they performed the rotation of planting and temporary resting by changing the field. The cultivated acreage per a house of total 5 villages in Myungseo-lee was just 0.4ha in average. The 70ha of the Swidden in Dooduk-village. Myungseo-lee, was sold to the Miwon corp. and the 342ha of that in Myungseo-lee was sold to Seohae-devlp.(SK forest). Those areas afforested. As the regulation plan for the Swidden began, the people in the site got paid for 300,000won as a migration fee. The special feature of the Swidden in Myungseo-lee was that the whole migration village was already established before the regulation plan for the Swidden began, and the yield was harvested by more than other villages the use of chemical fertilizer. And, in the Swidden agriculture, it showed the well-cultivated aspect, and the major harvest was various grains. The regulation Swidden in Myungseo-lee started in 1974.
