WTO 출범으로 세계 경제가 무역자유화를 통한 하나의 시장으로 빠르게 통합되고 있다. 특히 중국의 WTO가입은 세계무역뿐만 아니라 우리나라 임산업에도 크게 영향을 미칠 것으로 예상된다. 이러한 세계적 조류속에서 우리나라 임산업이 발전하기 위해선 경쟁력을 높여 나가는 것 외에는 대안이 없다. 여기에서는 우리나라 주요 수출임산물을 대상으로 한ㆍ중 임산물이 세계시장에서 갖는 국제 경쟁력, 상대국 또는 제3국에 대한 수출의존도, 상대국 또는 제3국 시장에서 보여주고 있는 상대적인 경쟁력, 그리고 각 국의 수입의존도 등을 비교 검토해 봄으로서 향후 우리나라 임산물의 대중국뿐만 아니라 제3국 시장으로의 수출확대를 위한 대응방안 마련에 기초자료를 제시하고자 하였다. With the launch of WTO, we can no longer think of our domestic interests and policies without reference to the wider global context. In particular, since China occuies important position in the world agriculture, forest industry, and trade, it is expected that China's joining to the WTO will substantially influence the world trade and forest industry in Korea. One alternative is to strengthen the international competition of our forest products for the development of our forest industry. In this context, the purposes of this paper are laid at the analysis on the international comparatives of some forest products in Korea and China, on the basis of Revealed Comparative Advantage Index(RCA), Exporting Dependent on a particular Country, Comparative Advantage by Countries (CAC), Market Share(MS), etc. This paper also suggests ways to strengthen the international competition of our forest producs in the market of China and Japan.

The purpose of this study is to figure out the necessity of forest insurance, by surveying forest insurance related questionnaires such as understanding of forest disaster control systems, preference of forest insurance types, and willingness to buy the insurance for forest owners. Therefore, this study can present the basic information for establishing a new forest insurance market. The willingness to buy the insurance for forest owners estimated by logit model and probit model. The result is shown that the older forest owner and group forest owner the probability of willingness to buy the insurance is decreased. But, In the case of more government subside to forest insurance payment, larger forest owner the probability of willingness to buy the forest insurance is increased.

The effects of essential oils on pH, pathogens, and volatile fatty acids (VFA) in two poultry litters were investigated through a lab study. Essential oil-added poultry litters were randomly divided to two groups: control (200 g poultry litter) and Treatment (50 g thymol/Briefly, 200 g broiler litter was treated with or without 50 g thymol (Control and T1, respectively; 1 groups) and 200 g duck litter was treated with or without 50 g carvacrol (Control and T2, respectively; 2 group). Adding thymol to broiler litter increased the pH, reduced pathogens, and did not affect VFA. Interestingly, adding carvacrol slightly reduced the pH of duck litter, but had no significant effect on reducing pathogens and VFA. This difference is probably because the essential oil used and the properties of the two litters are different. In addition, pH was thought to control the odor generated from the litter, but this has not been proven. Further field studies should focus on clarifying this point.
