In the Republic of Belarus as well as in the world acute problem of protecting forests from diseases and pests. The damage caused by root rot is essential, therefore, the problem of forest protection is an urgent task. The biologics has the greatest prospects in according with traditional methods of struggle. Deep method of cultivation of a mushroom Phlebiopsis gigantea with use of nutrient mediums on the basis of ethanol stillage and its components (fugat) is researched. Feasibility of use stillage as raw materials in production of a biological product for the wood protection against root decay is shown. The effect of different additives (sawdust, fodder yeast) on the accumulation of reactive biological product - oidy has been studed It was determined that the deep cultivation using sawdust of the highest accumulation oidy (1.5 $10^6units/ml$). It was also found that the stillage is the best breeding ground for fungus biomass accumulation (7.9 9.8 g / l) versus fugat (6.0 6.6 g / l). On the basis of research work the technological scheme for production of a biological product were developed. Based on the conducted studies, a technological scheme was proposed for obtaining a biological preparation by deep cultivation of the fungus Phlebiopsis gigantea.

The endoxylanase (642 bp; 213 amino acids) and ${\beta}-xylosidase$ (1,602 bp; 533 amino acids) genes from Bacillus sp. were amplified by PCR and separately inserted downstream of the yeast ADH1 promoters, resulting in the pAEDX-1 and pAEX plasmid. When the yeast transformants, S. cerevisiae SEY2102 harboring pAEDX-1 or pAEX, were grown on YPD medium, the total activities of the enzymes reached about 9.8 unit/mL for endoxylanase and 2.9 unit/mL for ${\beta}-xylosidase$. When the three kinds of xylan from oat spelts, birch wood, and corncob were hydrolyzed by treatment of recombinant endoxylanase and ${\beta}-xylosidase$, it was found that xylose, xylobiose and xylotriose were produced and xylose was the major product after 12 h reaction. In addition, with the higher amount of enzymes, the more amount of xylose was produced.

Five lignans including gomisin N (1), wuweizisu C (2), gomisin L1 (3), (+)-deoxyschizandrin (4), and gomisin J (5) have been isolated from the fruits of Schizandra chinensis. The structures of the isolated compounds were elucidated by analyzing MS and NMR spectra. Effects of the compounds isolated in this study on the dopamine content in PC12 cells were investigated to evaluate their inhibitory effectiveness. The gomisin N, wuweizisu C, and gomisin J showed 25.4%, 39.8%, and 35.1 %, respectively, inhibition effect on dopamine content in PC12 cells at the concentration of $50\;{\mu}g/ml$.

Korea is a small country with extremely high population density. Industrialization of the nation resulted GNP per capita of over 2,000$ in 1986 with an inevitable by-product, high level of pollution in many areas. Forest land is now acknowledged as not only a wood production site but also an origin of much more important intangible values, water and clean air, soil conservation, and recreational and scenic values. Mostly devastated forest land from Korean War has been recovered under the strong afforestation drive from the government. The first Forest Development Plan was mostly reforestation phase and the second Forest Development Plan is foundation establishment phase. The third and later Plans are to enlarge economical forest and to maintain sustatined yield phase. Forestry administration as well as forest research certainly played a great role in successful accomplishment of two Forest Development Plans. For effective planning and accomplishment of the third Forest Development Plan close cooperation among policy makers, forest managers and research workers are mostly required.

In recent years, young customers whose priority are on rationality and practicality of products and set a high value on space usage and storage efficiency have shown larger interest in knocked down furniture, thus its purchase has been on the rise. A baby bed design utilizing knocked down system suggested in this article, allows simple assembly and disassembly, easy transportation, easy movement, and also possible to recycle. Using laminated wood made of Douglas fir, a natural material, a baby bed is designed as knocked down structure. Its prototype is made to suggest easy assembly and disassembly design, which does not require any hardware. If efforts are put on the research of furniture design and its product development, focusing on the applicable usage and strength of knocked down furniture, it can become one of the solutions to the development of currently stagnant domestic furniture industry.

Ultrasonic cutting is a kind of eco-technique and cost-effective technique to be used for cutting of various materials such as baked product, fresh/frozen food, rubber, textile, wood, bone, etc. The performance of ultrasonic cutting is affected by design of cutting horn and cutting conditions. Specially the design of horn to resonate at the longitudinal direction is most important. To analyze the problems from which cracking and noise are often generated with conventional cutting horn, FEA is carried out, and then improved cutting horn which can reduce maximum stress and stress concentration is designed. Vibration characteristics, resonant frequency, gain, and amplitude uniformity of the cutting horn designed optimally are evaluated through FFT analysis and compared with those of conventional cutting horn.

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.

An automated manufacturing process mechanism for string musical instruments has been designed in this study. In contrast to other manufacturing products, classical string instruments try to preserve their traditional design shapes even in these days and involve variety of wood working(carpentry) characteristics including highly skilled curved surfaces treatments. Great efforts have been put to develop an integrated and automated system for improved product quality and process control, reduced physical labors, better safety etc. They, however, have been limited to devise jigs and tools with regard to selected processes due to lack of technology and research man-powers. We carefully examined the products and process characteristics, and an automated mechanism which overcome prevailing drawbacks has been derived.

During last decade there has been noticeable progress in the research of the biology of sapstaining fungi that cause considerable economic losses to forest product industry. The researches generated broad ranges of knowledge on sapstaining fungi regarding their occurrence on conifer wood, taxonomy, nutrient physiology, pigmentation biochemistry and molecular biology, and biological control. Major problematic groups in the sapstain production are Ophiostoma, Ceratocystis, and Leptographium genera. With Ophiostoma as a model, it is found that the type of carbon source is important in the growth and pigment production of sapstaining fungi. The operation of dihydroxy naphthalene (DHN) melanin pathway for black to bluish pigment production has been confirmed in those cosmetic fungi both at biochemical and molecular levels. The development of albino technology using nutrition competition has been shown to be promising as an environmentally friendly biological control method for sapstain control.
