Lipid oxidation and browning during fermentation of domestic Meju and Doenjang were examined in order to elucidate the antioxidative effects of browning products and phenol compounds from Meju and Doenjang. Peroxide values of lipids from Meju were detectable and slightly increased until 3 weeks of fermentation, but started to be decreased after 3 weeks of fermentation and notdetectable after 6 weeks. Peroxides were not detected in Doenjang during the whole fermentation, but started to be decreased after 3 weeks of period of 22 weeks fermentation. Carbonyl value were increased during the whole period of Meju fermentation, but started to be decreased at the early stage of Doenjang fermentation. Hydrophilic fraction of browning products from Meju was much higher than lipophilic fraction and the former fraction was dramatically increased at the early stage of the fermentation. But the both fractions maintained high values during Doenjang fermentation. Hydrophilic browning products and phenol and phenol compound in Meju showed strong antioxidative against linoleic acid.

Armington elasticity has been a methodology for analyzing how much imports could increase in response to importing price cuts, assuming the possibility of incomplete substitution of domestic and imported products. This study calculates Armington elasticity values in Korean fisheries sector and presents an analysis method for classifying items based on price and preference differences. The model is modified reflecting the characteristics of the fisheries market along with the typical OLS, PAM, and ECM models. The result's implication is that products with a high import growth rate do not necessarily show a high Armington value, but it could be seen that price is not the only factor facilitating fisheries imports increase. Considering the items of which demand increases due to importing price cuts have an indiscriminate demand between domestic and imported products, the results could be interpreted that the Korean fisheries importing market has been easily affected by the changes in import prices. Fisheries grouping by price and preference demonstrates that explanatory variables other than price should be considered when estimating import demand.

The import content of export (ICE) has served as an indicator of global integration for several decades. It is defined as the share of imported products embodied in exports and can be interpreted as the relative degree of the utilization of global production network (GPN) over the domestic supply chain (DSC) in terms of 'value-added.' This paper proposes two new indicators of global integration. They are defined as the ratios of imports (foreign products) to gross output (domestic products) generated by exports and can be interpreted as the relative degrees of the utilization of GPN over DSC in terms of 'production.' Both indicators are easy to compute and can be compared between years, between countries, between industries, and between groups of industries. The paper applies the new indicators to the recent edition of the OECD's Input-Output Database. Finally, the paper shows that the recent slowdown in international trade is mostly due to the decrease in the international trade of intermediate goods, with significant implications regarding the future of global integration.

The consumers' purchase experiences of some imported agricultural products (rice, sesame, garlic, onion, jujube, red pepper, oak mushroom, apple, dried persimmon) and their consciousness for the labelling of the country of origin for agricultural products in Youngnam region were examined in this study. The sample consisted of 438 women who lived in Taegu, Pusan and other cities of Kyungpook and Kyungnam, and the self-administered questionnaire for the survey was used. The main reasons to purchase the imported agricultural products were the wide distribution and low price of them. Most of the consumers were concerned about safety of the imported agricultural products but only a few people experienced unsatisfaction of the products. The price, quality, package, container, label, and safety of the examined products were evaluated worse than those of the domestic products. Generally, although they suffered unsatisfaction, the consumers did not complain because they wanted to avoid troublesome work, which means the consumers did not assert their rights. Some people did not know the labelling system for the country of origin and the place to charge the market violating it. Therefore, it will be necessary for the consumers to receive education about the labelling system for the country of origin and the compensation criteria for consumers' grievances and damages. The current labelling method for the country of origin generally met the consumers' preference but the consumers wanted to improve the position and color of the label. Most consumers could not differentiate the imported products from the domestic products. The results obtained from the survey suggest consumer education for the labelling system for the country of origin and the compensation criteria should be activated through various ways such as mass media and consumer organizations.

Objective: This study aimed to examine the level of risk perception related to pesticide contamination of food products and associated sociodemographic factors, as well as investigate the association with environmental pollution preventive behaviors. Methods: Based on data from Social Survey conducted in 2008 among a nationally representative sample of the population 15 years or older, we estimated proportions and 95% confidence intervals of the risk perception of pesticide contamination of food products. Logistic regression analyses were used to analyze the effects of sociodemographic status on risk perception. Results: Among respondents, those who feel anxious about the risks of pesticide contamination of domestic food products accounted for 40.4%, whereas the proportion rose to 87.0% with imported food products. These numbers showed that levels of anxiety about the pesticide contamination of imported food products were ranked at the top, and those for domestic products were at the bottom of the list of all environmental pollutants examined in the survey. Significantly related factors to anxiety about pesticide contamination of food products included women, the 40-50 age group, university graduates, married, non-manual employment, having school-aged children, and owning one's own home. The population attempting to prevent environmental pollution showed higher levels of anxiety about pesticide contamination of food products than did those who were not taking such steps. Conclusion: Compared to other forms of environmental pollution, Koreans show the highest levels of anxiety about pesticide contamination of imported food products. Therefore, it is necessary to establish appropriate regulations and transparent risk communication with the public about the safety of imported food.

Wood has different properties depending on the species or growth area. Therefore, in order to use wood efficiently, it is necessary to have a proper understanding of the characteristics of wood depending on the species and the appropriate use for them. In particular, in order to effectively use more than 1,000 species of woody plants in South Korea as wood, it is necessary to evaluate the characteristics of various Korean domestic woods and make a database of them. In this study, the anatomical properties (length and width of tracheid, cell wall thickness), physical properties (specific gravity and shrinkage), mechanical properties (bending strength, compressive strength, tensile strength, shear strength, hardness), and chemical composition (ash, extract, lignin, total sugar content) of Korean red pine which was grown in Pyeongchang-gun, Gangwon-do, South Korea were evaluated.

The purpose of this study is to systematize various clothing production methods that domestic fashion brands are utilizing to produce fashion products, and to propose effective clothing production methods according to the characteristics. The research methods are contents analysis method of the literatures, articles, reports, and interviewing method of the practitioners who are in charge of the production of fashion. First, the clothing production methods of the domestic fashion brands are categorized as follows. It is divided into a fashion brand management method and a promotion company entrustment method based on who carries out the clothing production and management. The fashion brand management method is subdivided into the 'rental-production', 'CMT', and 'self-production' methods. All three methods are performed at domestic and global sourcing, but the CMT method is more utilized at the global sourcing. The promotion company entrustment method is subdivided into the 'full consignment production method', the 'CMT method involving promotion company', and 'direct buying method by promotion company'. All methods are performed at domestic and global sourcing. Second, the results of reviewing effective clothing production methods, according to characteristics are as follows. If fashion brands control the production and management, they use all three fashion brand management methods. The fashion brands use the promotion company entrustment method when they wants to offer special products, or the number of items is large, or the production management is difficult, or the manpower and equipment size is reduced. The domestic sourcing is utilized by fashion brands and promotion companies when production management is required for high quality apparel production, in case of trendy and complex designs, spot production, and in small quantity production. The global sourcing is utilized by fashion brands and promotion companies when it comes to lowering the production cost, fashion brands preferred the mass production of apparel with design that can be pre-planned.

The morphological properties of various structure materials of domestic and foreign reconstituted tobacco products(RTP) were investigated by using the Bauer-McNett classifier and the image analyzer. The results of the fiber classification showed the fraction of the bigger size structure materials was larger in a domestic RTP than that in two foreign RTPs. In case of fine fraction, the domestic RTP had bigger fine fraction than two foreign RTPs. Images of each structure materials showed the scrap in the foreign RTPs kept the original shape which were rare in the domestic RTP fractions. Those results deduced that the raw materials in a foreign RTP process might be treated separately depending on the mechanical and morphological properties, which could reduce the amount of fine generation and increase the efficiency in raw material treatment.
