  • Forestry education in vocational high schools is one of the fundamental keys for achieving sustainable forest management. However, support systems for forestry education have not been well developed in Japan. Forest research institutes, which have accumulated relevant information, should have sufficient ability to develop new educational programs in this field. This study examined the possibility of support systems for forestry technical education by a research institute. Educational programs for vocational high schools were developed, and the programs were examined for their practical applications through a workshop for these teachers. We set the following five requirements for the programs: They should 1) incorporate new contents related to sustainable forest management, 2) be based on forestry education textbooks, 3) meet recent demands of the schools and society, 4) allow participants to learn through actual practice and experience, and 5) utilize readily available teaching materials. With these criteria, we developed the following two educational programs: (a) Forest management program to teach advanced techniques, (b) A timber-program to teach about biomass resources. The workshop was held on July $28^{th}$, 2007 with ten teachers attending. The programs were very interesting, who gave them high average evaluation of 4.6 on a scale of 1 to 5. Only a few issues need to be resolved before classroom instruction can begin, such as making wood structure easier to understanding for some teachers, and obtaining base maps of school forests. In conclusion, forest research institutes can effectively support forestry education by providing and implementing programs based on scientific information.

  • This study focuses on the application of multi-criteria performance measures based on the concept of equifinality to the calibration of the rainfall-runoff model TOPMODEL in a small deciduous forest catchment. The performance of each parameter set was evaluated by six performance measures, individually, and each set was identified as a behavioral or non-behavioral parameter set by a given behavioral acceptance threshold. Many behavioral parameter sets were scattered throughout the parameter space, and the range of model behavior and the sensitivity for each parameter varied considerably between the different performance measures. Sensitivity was very high in some parameters, and varied depending on the kind of performance measure as well. Compatibilities of behavioral parameter sets between different performance measures also varied, and very few parameter sets were selected to be used in making god predictions for all performance measures. Since different behavioral parameter sets with different likelihood weights were obtained for each performance measure, the decision on which performance measure to be used may be very important to achieve the goal of study. Therefore, one or more suitable performance measures should be selected depending on the environment and the goal of a study, and this may lead to decrease model uncertainty.

  • 본 연구는 숲에 대한 태도 척도와 공격성 척도를 활용해 초등학생의 숲에 대한 태도와 인식을 살펴보고 숲에 대한 태도와 공격성의 관계를 규명하였다. 숲에 대한 태도의 구체적인 특성을 살펴보기 위해 요인분석을 실시한 결과 '숲에 대한 흥미', '숲의 보호 및 중요성' 두 개 요인으로 나타났다. 요인의 집단 간 평균비교 결과 학생들은 숲을 흥미로운 장소로 인식하기보다 숲을 보호해야 하는 중요한 공간으로 인식하였다. 숲에 대한 태도와 공격성의 상관관계 분석 결과 숲에 대한 태도가 긍정적일수록 공격성 정도가 낮은 것으로 나타났다. 숲에 대한 태도에서는 '숲의 보호 및 중요성'이 상대적으로 높은 상관성을 보였고 공격성 중에서는 특히 행동공격성이 숲에 대한 태도와 관련 있는 것으로 분석되었다.

  • In an effort to analyze the impact of climate change, Gangwon provincial forest was divided into three sectors; forest ecology, forest disaster, and forest productivity and analysis of their current status from 2000 to 2009 and vulnerability assessment by climate change has been carried in this study. In case of vulnerability assessment, except for the forest ecology, forest disaster (forest fires and forest pests) and forest productivity sectors were analyzed in current status, the year of 2020, and 2050. It turned out that vulnerability of forest fires in the field of disaster would become worse and forest pests also would make more impact even though there is some variation in different areas. In case of the vulnerability of forest productivity there would be not a big difference in the future compared with current vulnerability. Systematic research on the sensitivity index used for vulnerability assessment is necessary since vulnerability assessment result greatly depends on the use of climate exposure index and adaptive capacity index.

  • We tested the hypothesis that alpine plants have special physiological and biochemical mechanisms in addition to their structural adaptation in order to survive under extreme conditions. The photosynthetic organs of Pinus pumila were used to examine the seasonal changes in sugar concentration, antioxidative enzyme, and lipid peroxidation. The concentrations of sucrose, glucose, fructose and reducing sugar were the highest in the leaves in April. But sugar contents in buds and inner barks did not respond sensitively on temperature change. Meanwhile superoxide dismutase (SOD) activity responded sensitively on the change of temperature and SOD in all tissues maintained high activity in April. Meanwhile anthocyanin content increased rapidly in June but the increase of anthocyanin content was not enough to prevent their tissues from the damage by the exposure of high temperature or other stress. In conclusion, under low temperature condition, P. pumila increased the concentration of soluble sugars and SOD activity in their tissues in order to overcome extreme environmental condition. But in summer, these stress defense system against high temperature might be disturbed slightly. This results in the increase of malondialdehyde (MDA) contents in three tissues by lipid peroxidation.

  • 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.
