  • 본 연구는 한국의 '생애주기별 산림복지' 시설사례들에 대한 연구를 통해 국내 산림복지시설의 특성을 분석하고, 이를 바탕으로 우리나라 산림복지 정책에 적용시킬 수 있는 시사점을 도출하기 위해 수행되었다. 이를 위해, 여러 가지로 산재해 있는 생애주기별 산림복지 시설사례들의 통계자료들을 하나로 통합하여 분석하였다. 우리나라 생애주기별 산림복지 시설의 특성에 대해서 살펴보면 첫째, 각 생애 주기에 해당하는 산림복지 시설들 간의 양적인 불균형이 나타나고 있다. 둘째, 생활권 주변 숲에 위치한 시설이 부족하다. 셋째, 시설들이 대부분 국공유림에 위치하고 있다. 그리고 이러한 특성을 바탕으로 다음과 같이 관련정책에 적용시킬 수 있는 제언을 할 수 있다. 첫째, 각 생애주기의 수요에 맞게 필요한 시설들을 골고루 설치할 필요가 있다. 둘째, 좀 더 생활권에 가까운 곳에 산림복지 시설을 만들어 접근성을 높일 필요가 있다. 셋째, 우리나라는 산림의 대부분이 사유림으로 구성되어 있다. 이러한 현재의 상황은 더 많은 국토를 고르게 활용하여 국민에게 산림복지의 혜택을 제공할 경우보다는 불리한 측면이 있다고 할 수 있다. 따라서 민간자본의 도입을 확대하고 사유림을 활성화시켜, 더 많은 사람들에게 산림복지의 혜택을 제공하고 국 공유 및 사유림 산림복지시설의 양적인 균형을 맞추기에 유리한 조건을 형성 필요가 있다.

  • This paper assesses the stmpage value of Korean white pine (Pinus koraiensis) stands in the Research Forest of Kangwon National University. Assessment was done by means of the cost value method (Faustmann formula) for age class I, Glaser method for age class II-V, and inversion market method for age class over VI. Generally the value of stumpage is calculated by the inversion market method in the market. However, immature trees and middle age class trees are not assessed in market, and the Korean forest is not old enough to harvest. So, when forests are damaged by attacks from forest fire, blight and harmful insects, the forest cannot be compensated for the loss from the government or insurance company. For this reason, the value of all-age class trees are calculated by using appropriate methods. As a result, the value of age I class stands (0.3 ha) is calculated as 1,786,305 (won), age II-Vclass stands (22.1 ha) 206,677,975 (won) and age VI class and over stands (24.8 ha) 523,789,603 (won).

  • This study was carried out to examine the perceptions of consumers and forest product manufacturers in South Korea about forest certification and to identify their willingness-to-pay for certified products by personal interviews. Sixteen percent of interviewees knew and heard about forest certification. However, fifty-six percent of interviewees had an intention to participate in forest certification system. The consumers' group can be described in relative terms as the male of 30 age bracket. The average price premium charged to consumers was higher than one paid to manufacturers, and thus manufacturers are willing to include the additional costs for certified products.

  • Reticulitermes speratus is commonly found in Asia, including Korea and Japan. We recently analyzed the 5' region of mitochondrial cytochrome c oxidase subunit I to perform a phylogenetic analysis of R. speratus KMT1, isolated in Seoul, Korea. Our results, using COXI, suggest that the taxonomy of R. speratus should be reconsidered with regard to the subgenus group. A similar phylogenetic analysis by COXI and COXII demonstrated the reliability of COXI genetic information in a molecular phylogenetic analysis of termites.

  • With the intention to solve environmental problems caused by synthetic plastics from petroleum resources, biodegradable polyurethane foams and thermosetting moldings were prepared from biomass, such as wood and wheat bran by liquefaction method. Biodegradability of these biomass-based polymeric materials was investigated. In activated sludge, polyurethane foams from liquefied wheat bran and thermosetting molding from phenolated wood were decomposed approximately 14% and 29% for 20 days, respectively. One of the wood fungi, Coriolus versicolor was able to grow without supplemental nutrition, only with distilled water and polyurethane foam as a nutrition source. Risk assessments were also conducted and results showed that estrogenicity, mutagenicity, and carcinogenicity were not observed in the extractives of biomass- based polymeric materials.

  • 본 연구는 환경친화적이고 경제적인 녹색임도 건설에 기초 정책자료를 제공하고자 우리나라의 산지지형 및 산림특성을 고려하여 임도밀도를 산정하였다. 그 결과, 효율적인 산림관리 및 보호를 도모하고 공익적 기능의 고도 발휘를 위한 사회간접자본(SOC) 개념에서의 기본임도밀도는 8.57 m/ha로 나타났으며, 또한 지속가능한 산림경영 체계를 구축하기 위한 산림경영기반시설 개념에서의 적정임도밀도는 14.01 m/ha로 산출되었다.
