Climate changes from global warming and reduction in agricultural land result in volatility of prices of agricultural products, causing a imbalance of food market in Korea. It is necessary to develop a transnational food industry cooperation system among Korea, China and Russia that directly or indirectly affect food industry in terms of the whole industrial network. This study analyzes the value chain and linkage in the agriculture, forestry and fisheries industries in three nations. The unit structure and the industrial patterns of three nations were derived using the World Input-output Table (WIOT) from 2004 to 2014 every five years. This paper is expected to contribute to develop food security cooperation in the northern part of the Korean peninsula and to promote the mutual growth of food industry through industry linkage and cooperation.

DB Integration website(tentatively named Food Processing Aptitude Information Center, FPAIC) has been designed through a "high-value products development project(2013)". Basically, the project aims to secure connections between food raw materials and processing industry, a variety of information sources, and users's convenience. It also aims to build the industry-university-based mutual growth in the food industry through sharing of processing suitability and material research on food raw materials. FPAIC consists of raw material story, information of sample characteristics, food processing study, preceding research data, food industry trends, and understanding of food processing. The major database of research on Food Processing is provided on information of sample characteristics, and food processing study. Currently the web site has 36 raw material stories, 380 information on sample characteristics and food processing studies, 1,600 preceding research data about 31 food raw materials. The web site also provides information on 70 useful web sites, as well as 77 food industry trends, 27 basic information about food processing.

Gloss is very important optical property influencing the perceived quality of the paper surface as well as the surface after printing. Although the average gloss level of paper products or printed images is important to meet end use specifications, the occurrence of gloss mottle, or non-uniformity of gloss, is often of greater concern for meeting quality requirements, especially for the high gloss paper. Gloss variation originates from the irregularities of paper surface, especially surface roughness of paper. Roughness of paper can be divided into micro-roughness (under $1\mu m$ scale in variation) and macro-roughness (over $1\mu m$ scale in variation) depending on the scale of the irregularities. A clearer understanding of the gloss variation of paper can be achieved by separating the contributions of these two scales of roughness, and characterizing them independently. In order to do this, a novel gloss measuring method was introduced. This can detect local gloss with very high resolution. The effect of macro-roughness on gloss variation, which was identified by the measurable surface topography, was separated from the total gloss variation by using this method. The effect of micro-roughness was then estimated indirectly. The local gloss variations of various paper samples were then evaluated to demonstrate the utility of this approach.

This study was carried to investigate the effects of steaming and four different drying methods on the longitudinal liquid permeability of Korean pine (Pinus koraiensis Sieb.et Zucc.) board. Four drying methods were air drying, conventional kiln drying, microwave-vacuum drying and high temperature drying. Darcy equation was used for calculating the specific permeability of the small sapwood specimens taken from the treated boards while capillary rising method was used for the heartwood specimens. The sapwood specimens were extracted with water and benzene-alcohol solution to examine the mechanism of liquid flow in treated wood. No significant correlation was found between specific permeability and the number of resin canals of the sapwood specimens. Extraction decreased the differences of specific permeabilities of the sapwood specimens between the five treatment methods. The effects of extraction on the longitudinal permeability are different between five treatments. The fluid path in heartwood was observed by dynamic observation method.

In previous report, we investigated the impact of hexeneuronic acid and some residual extractiveson lignin determination. These non-lignin components severely interfered lignin content determination which also affect on the oxygen delignification comparison between aspen and pine unbleached kraft pulps. Very different pattern was observed whether based on uncorrected conventional kappa number or based on corrected kappa number in oxygen delignification comparison. Lower kappa number aspen pulps showed poor response to oxygen delignification when kappa number was used as lignin determination method but better response with using the acid lignin method. Phenolic hydroxyl group in kraft pulps were also compared based on uncorrected or corrected kappa numberfor lignin content. Based on uncorrected kappa number, lower kappa number oxygen-delignified pulps had lower phenolic hydroxyl group. However, lower kappa number oxygen-delignified pulps showed much higher phenolic hydroxyl group based on the corrected lignin content. For accurate comparison for residual lignin properties from different pulps, lignin determination should be corrected from non-lignin components contribution to lignin.

Antimicrobial activities of extracts of Forsythia suspensa fruits and Dendranthema indicum buds and flowers against bacteria; Escherichia coli, Staphyloccus aureus, and Bacillus subtilis, and fungi; Aspergillus flavusn, Rhizopus stolonifer, Penicillium citrinum, Aspergillus niger, and Saccharomyces carlsbergensis, were investigated. The plants were extracted with 70% ethanol and the extracts were used for antimicrobial activity assay. All extracts exhibited significant inhibition activity against microorganisms at concentrations ranged from 1.66 to $100\;{\mu}l/ml$. The inhibition activity by the extract of D. indicum buds was stronger than by the extract of F. suspensa fruits and D. indicum flowers. D. indicum buds showed antimicrobial activity against S. aureus which was comparable to other medicinal plants. F. suspensa fruits and D. indicum flowers was suggested to be valuable sources as antimicrobial ingredients in food industry.

Recent development of industry and urbanization in the interior of mountainous area increases the possibility of occurence of natural disaster, such as flood, landslide and deblis-flow. Erosion control facilities, which were the most significant activity to riverbed fixiation, were constructed at the downstream of the experimental basin. In the mountain torrents, the complex bed load transport has occurred by the drift of running water, and resulting in a formation of terrace deposits. Especially, channel migration caused by scouring and deposition frequently occurs at the wide areas of the river bed. Consequently, the unsymmetrical river bed charactristics indicate the degree of the channel migration.

산림의 경제적 가치의 중요성에 따라 산림이용과 개발의 패러다임이 산림정책의 지배적 패러다임으로 등장하였다. 산림이 웰니스의 중요한 수단으로 인식되면서 이용과 보전의 융합이 모색되었고 산림정책의 패러다임도 산림을 이용한 휴양, 복지 및 웰니스(wellness) 등 새로운 정책가치들을 지향하게 되었다. 따라서 본 연구는 산림정책에 새로운 가치들이 어떻게 융합되었는지를 컨텐츠 분석과 네트워크 분석이 결합된 텍스트 네트워크 분석을 통해 분석하고자 하였다. 분석결과에 따르면, 제4차 산림기본계획에 비해 제5차 산림기본계획에서는 임산물 생산에서 벗어나 산림이용과 산림휴양기능이 강화된 것으로 분석되었다. 산림을 통한 치유, 건강, 산림의 복지적인 기능 등에 대한 정책과 산림이용과 보전이 융합된 경영기반 마련에는 미흡한 것으로 나타났으며 한국의 산림정책에서 지속가능한 융합패러다임이 보이고 있다. 정책적 함의로서 국가산림기본계획 수립에 있어 산림이용과 보전을 융합할 수 있는 정책역량의 강화가 필요하다는 점을 제시할 수 있다.
