The physicochemical characteristics of 4 domestic wheat flour products were compared to those of 4 imported wheat flour products marketed in Korea. The contents of moisture, ash, protein, total dietary fiber (TDF), color (L, a, b), whiteness, solvent retention capacity (SRC), water absorption index (WAI), water soluble index (WSI), pasting characteristics by rapid visco analyzer (RVA), and principle component analysis (PCA) were analyzed. The domestic wheat flour products were composed of higher content in ash and protein, compared to the imported wheat flour products. The domestic wheat flour products had lower SRC and WSI characteristics than the imported wheat flour products. The values of lactic acid SRC (LASRC) in the imported wheat flour products showed an increasing trend as the protein content increased. The differences in viscosity were observed in the domestic wheat flour products. However, no major significant differences of viscosity were found among the imported wheat flour products. The result of PCA showed a consistent trend in the imported wheat flour (strong, medium, and weak), while a consistent trend was not shown in the domestic wheat flour products. Therefore, further research is needed to standardize the different types of domestic wheat flour products.

The purpose of this paper is to analyze the relationship between the level of satisfaction of domestic Environment-friendly agricultural products and purchase intent of imported organic products. To accomplish the objective of the study a consumer survey was administered for quantitative analysis regarding consumption patterns. The bivariate probit with sample selection model was employed for empirical analysis on the relationship. The estimation results showed that to increase continuously the consumption, it is necessary to improve the quality satisfaction compared to the price, and that it is also necessary to increase the reliability of the certification system and the awareness that the consumption is helpful for health promotion to increase the quality satisfaction compared to price. In addition, it was concluded that in order to induce the purchase of domestic organic products rather than imported organic products, efforts to improve the safety of domestic products, remove the risk of residual pesticides, and increase the reliability of domestic products compared to imported products are needed. Therefore, to reduce the proportion of purchases of imported organic products and increase the consumption of domestic products, raising awareness that the consumption is conducive to health promotion, enhancing the safety of domestic products, and providing accurate information on the safety of imported products are required.

The purpose of this study lies in analyzing the effects of Fukushima nuclear plant incident, due to the earthquake in the northeastern part of Japan, on South Korean consumers'responses to domestic marine products. Survey results show that the response to the event by all consumers is not significant, but not by individual consumer. Empirical results show that if consumers are relatively more interested in health issues, if they consume mollusca relatively more among marine products and if they are with children under the age of 14, they increased the consumption of domestic marine products while decreased that of Japanese seafood. On the contrary, if consumers take shellfish products relatively more among seafood, they reduced the consumption of domestic marine products as well as Japanese ones.

Heavy metal ingredients of eyeliner product could cause side effect ranging from simple irritation, keratitis, corneal epithelium inflammation, eyelid dermatitis and dry eye symptoms have been reported. This study was conducted in order to prepare fundamental data for acceptable quality level heavy metal ingredients in the domestic and foreign cosmetic brand eyeliner products and to assess theirs the heavy metal concentrations. We measured the concentration of 5 heavy metals in 10 eyeliner products using ICP/MS-LC. According to the results, the average metal concentrations were as follows.; In case of domestic eyeliner products, 289.4 ppm for aluminium(Al), 304 ppm for manganese(Mn), 44 ppm for nickel(Ni), 0.58 ppm for arsenic(As) and 0.35 ppm for lead(Pb). In case of Foreign eyeliner products, 11337.8 ppm for aluminium(Al), 1678.8 ppm for manganese(Mn), 74.2 ppm for nickel(Ni), 1 ppm for arsenic(As) and 0.8 ppm for lead(Pb). Foreign products contained higher amounts of the two elements(Pb, As) compared to domestic ones. Also, greater concentrations of arsenic(As) were detected from waterproof products than non-waterproof ones. In conclusion, for safety reasons we suggested the amounts of heavy metals from the domestic and foreign eyeliner products. This finding will be helpful to provide the fundamental data which is standard of toxicological heavy metals acceptable on eyeliner products.

This study proposes development strategies for domestic e-commerce of agricultural products. So far, it grows quantitatively so fast, but because of lack of continuous management, it does not work properly. Previous studies have some outcome for vitalization of e-commerce, but they have limits that they neglect rapid changes of e-commerce circulation structures and practical problems farmers go through when they sell their products. This study deals with these problems more than previous. The first phase of this study analyzes two cases of overseas successful and failure e-commerce sites of agricultural products, for example, Wine.com and Webvan.com. The second phase analyzes As-Is and distribution structure of domestic e-commerce of agricultural products. Finally this study asserts three strategies for domestic e-commerce of agricultural products based on Web 2.0 environment.

The food crisis is gradually augmented, which derives from a world-wide process. And it is the actual conditions for which there is no solution on national level. Rice is a fundamental agricultural products, and it makes up a large percentage in the Korean farming industry. Especially, the environment around the domestic rice market has rapidly been changing and shrinking because of the open policy in the International market. In order to compete with the international market, Korea must be strong in stable-based construction and international marketing strategies of domestic rice products. Most of consumers recognize the importance of developing a brand-name rice. However, the degree of recognition on the brand-name rice is still very low. The Purpose of this paper Is to drive brand marketing strategy for positioning of domestic rice products.

High temperature operating test, temperature humidity test and temperature cycling were performed at various test levels for solid aluminum electrolyte capacitors made by domestic manufacturing company and foreign advanced manufacturing company. It was found that main failure mode of solid aluminum electrolyte capacitors was the decrease of their capacitances. The decrease of their capacitances has the same pattern in these tests. Test result for comparison of characteristics between domestic products and foreign advanced products shows that domestic products have the shorter lifetime and their capacitances decrease more rapidly in high temperature operating test and temperature humidity test. Also in these tests, accelerated tests for high temperature operating test and temperature humidity test were developed.

In order to develope domestic carburizers, the experiment was carried out by applying crystallization heat treatment to domestic anthracites and also to foreign products to compare with domestic anthracites.The present work was mainly concerned with the effect of their degree of crystallization of carbon-bearing materials on carbon pick-up in molten iron.Those effects were evaluated by the measurement of density, chemical composition, specific electric resistivity, and X-ray intensity of carbon-bearing materials. Experimental results thus obtained were summurized as follows. 1. The degree of crystallization of domestic anthracites and foreign products was increased with increasing heat treatment temperature. 2. The more degree of crystallization, the shorter the dissolving time of domestic anthracites in molten iron was obtained, while that of foreign products was remained constant. 3. As the degree of crystallization of domestic anthracites and foreign products was increased, the carbon content as well as carbon recovery in molten iron was increased.

The objective of this study is to analyze the value of attributes of agricultural products in school food service using hedonic price model and choice experiment. In the case of potatoes, bean sprouts, and tomatoes, environment-friendly agricultural products rather than conventional ones, and domestic price premiums exist rather than Chungnam. The higher the price, the higher the margin rate. Conventional agricultural products were more profitable than environment-friendly ones, and domestic products were more profitable than Chungnam. In consumer preferences, environment-friendly agricultural products are preferred over conventional agricultural products and local products (Chungnam, Cheonan, Asan) rather than domestic ones. This is the opposite result of the Hedonic price model estimation that Chungnam has a lower price premium than domestic in the case of origin. This study is meaningful by analyzing the attribute value of agricultural products used for school meals in Chungnam and comparing them with the willingness to pay consumers. With the results of this study, it is necessary that discussions on supplementing the value of local products used in Chungnam school food service.
