Many consumers are concerned about the high levels of salt intake owing to the accompanied risk of chronic diseases. Due to this dietary concern, the food industry has recommended the reduction of salt content in many products. However, the addition of salt to meat products improves their quality and sensory properties, including saltiness, color, juiciness, and texture. Because quality deteriorations could induce decreased sensory scores owing to salt reductions, the challenges involved in improving the quality of reduced-salt meat products have been addressed. During the development of low-salt meat products, it is important to reduce sodium content and address the problems that arise with this reduction. Modified salt, organic acids, amino acids, nucleotides, hydrocolloids, high-pressure, ultrasound, electric pulsed field, and irradiation have been suggested as strategies to replace or reduce sodium content, and sensory scores could be improved by these strategies. Therefore, when developing a low-salt meat product, several perspectives must be considered and the latest technologies that could resolve this problem should be adopted.

Objectives: To investigate the characteristics of topical agents including natural products using for atopic dermatitis treatment via a review on the cases and clinical trials. Methods: Through a search on Pubmed, EMBASE, Cochrane library, DBPIA, NDSL, and OASIS, we selected papers that applied natural products externally for atopic dermatitis and analyzed them. Results: Finally, Seventeen papers were selected. As the primary outcome, changes in the SCORAD and EASI, were the most used. The most frequent type of external formulation was cream. In terms of the frequency of use, it was used at least twice a day in all studies. When evaluated based on SCORAD, EASI, SH and TEWL, the improvement effect on atopic dermatitis was highest when the ointment formulation and the moisturizer formulation were used. A few side effects of topical agents including natural products were observed, but most were mild symptoms and no serious side effects occurred. Conclusion: This study is meaningful in that it has drawn a significant trend for studies that have been published in the last 5 years that contain a single intervention for topical agents including natural products, and that it presents the direction and evidence for the application of external therapy to increase the therapeutic effect of atopic dermatitis.

This study aim to use the GTAP model to analyze the impact of RCEP Fermentation in the Korean manufacturing industry by quantifying the RCEP tariff commitment table. The research results show RCEP has boosted output in all sub-manufactures except wood and printed matter due to increased export volumes. Wood products, on the other hand, are more reliant on imports due to lower production due to lower domestic sales or overall exports. After RCEP came into effect, the import and export scale of Korea's manufacturing industry expanded effectively. Among them, the positive impact on the intensive low-tech manufacturing industries such as clothing and leather products, wood products and printing products, and food, beverage and tobacco products is greater than the positive impact on the technology-intensive medium and high-tech and high-tech manufacturing industries. And found that the growth rate of Korea's manufacturing trade is basically proportional to the tax reduction rate of RCEP. Finally, in order to promote the development of the manufacturing industry, some suggestions are put forward that need the government's policy support and strengthen the regional cooperation with RCEP member countries.

There has been a gradual increase in distribution of counterfeit products and resulting damage cases from companies and consumers. It examines which antecedent variables have significant effects on consumer perceived satisfaction or regret. To test the related hypotheses, such antecedent variables as the utilitarian value, the hedonic value, legal regulations, and ethical mentality of consumers were examined and also did whether these factors have differences between Korean and Chinese consumers. Findings from the empirical analysis are as follows. First, Korean and Chinese consumers' perceived utilitarian value and hedonic value in counterfeit products in contrast to original products are found to have a positive influence on consumer perceived satisfaction with counterfeits while they have a negative influence on consumer perceived regret with counterfeits. Second, in the case of Korean consumers, the hypothesis that legal regulations on counterfeit products will influence the degree of regret with counterfeit products has been rejected. And it is found that the more ethical Korean consumers are, the more regretful for their post purchase they feel. Third, in the case of Chinese consumers, the hypothesis that legal regulations and ethical on counterfeit products will influence the degree of regret with counterfeit products has been rejected. Therefore, it can be said that the results in this paper provide significant implications for government policy, legal regulation and enforcement, and some need for a change in consumer consciousness and attitude as well as for marketing strategies of Korean and Chinese famous brand manufacturing companies.

The purpose of this study was to grasp the utilization of traditional Korean Patterns used for fashion cultural products. To achieve this purpose, this study examined the range of fashion cultural products through literature review, previous researches, and market surveys and analyzed the situation of fashion cultural products and the kinds, expression methods, expression techniques, and repeat styles of utilized patterns. The analysis results are as follows. First, in the use of traditional pattern, the most frequently-used fashion cultural products were small and inexpensive accessories, followed by fashion apparel, miscellaneous goods, and living cultural goods. Second, the most frequently-used traditional patterns were plant patterns, especially flower patterns. The next frequently-used ones were mixed patterns, especially in the mixture of flower and letter patterns, and $cloisonn\'{e}$ and flower patterns. The next frequently-used traditional patterns were animal patterns(especially butterfly patterns), followed by geometric patterns, lucky omen patterns, and letter patterns. In the expression methods of used patterns, most products except handicrafts preferred simplified patterns to real patterns. Finally, in the expression techniques of traditional patterns, the most frequently used technique was traditional embroidery, followed by the use of weaving fabrics such as fine gauze and brocade which are used for Hanbok. Also, transfer dyeing which is one of printing techniques, DTP(digital textiles printing), a mixed technique which adds embroidery to weaving fabrics, hand-painting, and a gilt technique were used. The results of this study suggest that most fashion cultural products except few designers' works attached weight to some specified patterns and expression techniques regardless of the characteristics of products since there is little understanding of a variety of patterns and are few researches and development on expression techniques.
