Carbohydrate analysis is important in studying structure and activity of complex polysaccharides. New analytical method was applied to get an information on the composition of polysaccharides showing antitumor activity. Monosaccharides were labeled with 7-amino-1, 3-naph-thalenedisulfonic acid (7-AGA) by reductive amination and separated by HPLC. Five kinds of polysaccharides from Basidiomycetes were hydrolyzed and analyzed in combination with electrophresis and HPLC. At the same time, alditol acetate derivatives were prepared and analyzed by gas chromatography. Two different techniques using different derivatization methods showed very similar results. The monosaccharides from Coriolus versicolor and Cordyceps militaris were glucose and galactose. Phellinus linteus composed of glucose, glactose, mannose, arabinose and fucose. The HPLC method with fluorescence detector was very sensitive compared to other methods.

The paper deals with the analysis of the effectiveness of acoustic emission monitoring and diagnostics of engineering products. We discuss the results of the processing results of the field experiment to study the acoustic emission in the alloy and its welded joints in the presence of technological defects. We study the characteristics of the output of acoustic emission signals at different stages of elastic-plastic deformation of alloys. Analyzed acoustic chart and the output waveform of the acoustic emission for the different types of welds. Studies have shown the effectiveness of the Acoustic emission techniques and help improve the accuracy of non-destructive testing systems in problems of automation and control.

227 red yeast strains were isolated from air (60 isolates), plant flowers (45 isolates), soil (40 isolates), water (37 isolates) and dairy products (45 isolates). On the basis of 33 different physiological and morphological properties, the isolated strains were assigned to 6 species belonging to 4 genera. Rhodotorula mucilaginosa and Cryptococcus albidus were the most dominant species among red yeasts of the air, plant flowers, water and dairy products, whereas Cryptococcus albidus and Rhodotorula glutinis were prevailed in soil. Cryptococcus laurentii was represented by considerable number of strains, whereas the other spesies were of low occurrence. Noteworthy was the isolation of 2 different groups of isolates belonging to Rhodotorula glutinis. These groups were differentiated from each other on the basis of rhamnose, cellobiose and arabinitol assimilation and growth at $37^{\circ}C$. Systematic position of Rhodotorula glutinis was discussed.

China has been aware of the urgent need of developing electronic and information industry in order to improve its productivity. Since 1991, IT industry has been one of the main factors to influence China's economic growth. In the results of the efforts to develop its IT industry, China has achieved average 25% yearly growth rate of IT manufacturing industry since 1991. We will take a look at haw the main IT products' performances was, how the role of IT industry was in China economy and in China's trade and how the prospect of China IT industry will be. However, we need to know that, depending an the different areas, the environment of the China's IT industry will be quite different. In China, the east coastal area has the better environment of technology, menpower, infrastructure, and fund for the development of IT industry and the IT industry of this area is very competitive, comparing with the middle and west area.

Rebuilding an existing paper machine is often a very profitable way for papermakers to increase the cash flow created by an older paper machine. Metso Paper has placed particular emphasis in recent years on developing concepts and products specifically for rebuild needs. The outcome of this work can now be seen as a wide selection of products offering quite possibly the best coverage of all time of specific improvement targets. Different needs can be addressed through truly different solutions. Selection the best-fit alternatives will offer great upgrade options for all paper machines and paper grades. Metso Paper's long experience with high-speed paper machines has been put to good use to create more cost-effective small and mid-sized solutions with the reliability and quality of bigger and faster paper machines. This paper has discussed some of the most interesting and latest configurations available today for paper machine and finishing area rebuilds.

In this paper, a mathematical model is developed for economic design of multi-stage distribution system that consists of factory, central distribution centers, local distribution centers and retailers. The retailers are supplied products from different stage suppliers according to order size. The retailers are supplied products from factory if demand amount is large, central distribution center if medium, local distribution center if small. The economic design is to determine the economic size of facility factors that consist of distribution system. The cost factors are transportation cost from supply places to demand places, handling cost at distribution centers and inventory holding cost at retailers. It is to determine the transportation route of each retailer, the size and number of the vehicle at factory and distribution centers, the handling amount at distribution centers in order to minimize the total costs. The mathematical model is represented, the solution procedure is developed, and a numerical example is shown.

Increasing product variety based on product family and product platform provides a company with a competitive advantage over its competitors. As products become more complex, short-life cycled and customized, the design efforts require more knowledge-intensive, collaborative and coordinating efforts for information sharing. By sharing knowledge, information, component and process across different families of products, the product realization process will be more efficient, cost-effective and quick-responsive. Formal Concept Analysis (FCA) is used for analyzing data and forming semantic structures that are formal abstractions of concepts of human thoughts. A Web Ontology Language (OWL) is designed for applications that need to process the content of information instead of simply presenting information to humans. OWL also captures the evolution of different components of the product family. The purpose of this paper is to develop product variety modeling to increase the usefulness of common platform. In constructing and analyzing product ontology, FCA is adopted for conceptual knowledge processing. For the selected product family, product variety Ontology is constructed and implemented using prot$\'{e}$g$\'{e}$-2000.

Tissue culture systems to optimize regeneration plant species of Ocimum spp were evaluated as a method to micropropagate individual plants and to better study their biology in vitro. Ocimum species were also evaluated for the production of natural plant products during and following the regeneration process. The primary goal of this project was to enhance the regeneration efficiency of basil. Several factors were examined using different Ocimum species and commercial varieties. The effect of cytokinin combination, activated charcoal, gelling agents, and different carbon sources were investigated. Anthocyanin callus spots were produced only in four varieties among six tested. 'Sweet Dani' showed the best results on anthocyanin accumulation, while 'African beauty', 'Tree basil' and 'Methylcinnamate' produced only a few spots. Shoot regeneration was only achieved from 'Sweet Dani' explants. As the activated charcoal concentration increased, callus formation rate decreased respectively compare to the controls for all varieties. There was a decrease in callus growth with increasing concentration of agar and phytagel.

This research examined how customers evaluate fashion brand collaborations in speculating the collaboration factors, product, model, and designer. Respondents evaluated 8 different collaborate case cards from 1 to 8, presenting a certain fashion brand, who had recently teamed up with various kinds of product companies for collaboration. Product was found as the most important factor in evaluating the collaboration case cards, analyzed through Conjoint Analysis. Respondents segmented additionally by clothing involvement valued different collaboration factors; products for the high clothing involvement group and messenger and designer for the low clothing involvement group. All the segments and respondents chose the best the card presenting blue jeans, Mr. Chang, and B.S. Choi, as similarity for products, fame for mdoel, and similarity for designer, respectively.
