This study was conducted to improve the quality of Kongsulgidduk prepared with soyflour and sweeteners. The quality was affected by the type of sweeteners used (sugar, syrup, honey), as well as the amount used (5-20%). Rheological properties showed that when more sugar was added to Kongsulgidduk, the hardness, gumminess and brittleness were lower. In addition, more than 10% sugar led to a significant decrease in hardness, gumminess and brittleness. The addition of honey increased the hardness, but decreased cohesiveness and brittleness of Kongsulgidduk. When color was evaluated, the L-value and a-value decreased, but the b- value increased as sugar was added. The addition of honey resulted in a decreased L-value. Sensory evaluation revealed that the addition of sugar resulted in better overall quality. The color score was highest when 5% sugar was added, while the flavor, moisture and chewiness scores were best when 10% sugar was added. Sweetness and consistency were good when 20% sugar was added. Honey improved the color, flavor and chewiness of Kongsulgidduk; however, sugar produced the best moisture, consistency and overall scores.

The purpose of this study was to investigate the effects of the addition of various amounts (0, 1, 3, 5%) of Mokdanpi(P. suffruticosa) powder on the shelf life and the physicochemical, sensory characteristics of rice cakes and noodles to examine the possibility of using Mokdanpi as a natural food preservative for food products. The decrease in the moisture content of rice cake and noodle samples during storage was much less in Mokdanpi-added groups than the control group. The color L value increased and a and b values decreased in the rice cake samples, and color L value, b value decreased and a value increased in the noodle samples during storage. The microbial growth was less in Mokdanpi-added groups than the control group. In sensory evaluation, there were no significant differences among the control and 1, 3%-added groups in terms of color, flavor, taste, moistness, cohesiveness and overall quality; however, 5%-added groups received significantly less score than others (p＜0.05). As the storage time increased, the sensory scores decreased significantly in the control and 1 %-added groups of both rice cakes and noodles (p＜0.05), but no changes were observed in 3, 5%-added samples. The results suggested that Mokdanpi is effective in increasing the shelf life and inhibiting the staling of rice cakes and noodles.

The Korean government introduced the $6^{th}$ industrialization in the agricultural sector to increase farmers' income and value-added agricultural products. The U.S. government has also supported farmers' efforts to increase their income and value-added products in a similar way even though the $6^{th}$ industrialization is not the usual concept in the U.S. Especially, direct-to-consumer and intermediated marketing is one of the main methods to increase farmers' income and value-added agricultural products in the U.S. The purpose of this paper was to analyze direct-to-consumer and intermediated marketing in the U.S., through a survey and frequency analysis. The results of this study are as follows: First, U.S. farmers have shifted their concern and efforts from direct-to-consumer marketing to intermediated marketing because intermediated marketing may offer higher value-added agricultural products. However, consumers' perception and interest are higher for direct-to-consumer marketing than for intermediated marketing of agricultural products and related services. Consumers also will increase the portion of consumption of agricultural products and related services through direct-to-consumer marketing. This difference between farmers and consumers may cause difficulties in increasing farmers' income and value-added agricultural products in the U.S. Korean farmers may have same problem in the future, even though they have not encountered it yet. Especially, the Korean government needs to develop the capabilities of farmers so that they can solve this problem.

Purpose - This paper empirically explores the RCA of electrical equipment trade between China and Korea from the perspective of gross trade and value-added trade. The goal of this paper is to scan the electrical equipment's RCA, the decomposition of gross exports, and the impacts of an exerted shock. Design/methodology - We applied the domestic value-added method in measuring the RCA, which could be more accurate than traditional RCA since it excludes foreign value-added. Based on the research purpose, this paper follows the framework of Koopman, Wang, and Wei (2014)-as extended by Wang, Wei, and Zhu (2018). It extracts the data from the 2019 Multi-regional Input-Output (MRIO) databases compiled by the Asian Development Bank in January 2021. Findings - After rigorous examination, the main findings are as follows: First, the electrical equipment sector maintains a consistent comparative advantage in either assessing method. Second, China exports more gross goods of electrical equipment to the world than South Korea does, but there is a trade deficit with Korea. Third, South Korea and P.R. China are the most significant bilateral partners of foreign value-added sourcing. Finally, it is surprising that there is a shock on electrical equipment; the partner's service, as well as manufacturing sectors, would be affected. Originality/value - This paper explores the revealed comparative advantage between Korea and China from traditional gross export and value-added perspectives. Second, we apply the information from the 2019 MRIO database compiled by the Asian Development Bank in January 2021, reflecting the current situation. Third, this paper analyzes the electrical equipment and the impacts on other parties' sectors. Finally, we carry out the subjects that deserve to be investigated in the future.

The principal objective of this study was to develop processed food with the effect of extract from Angelica gigas Nakai by assessing the quality characteristics of cookies. Cookie samples were prepared with shredded extract from Angelica gigas Nakai at varied levels of 0, 1, 3, and 5%. The pH of dough decreased significantly with the added extract from Angelica gigas Nakai and the density increased significantly in the 5% added group(p<0.05). The spread factor decreased significantly as the added extract from Angelica gigas Nakai increased(p<0.05). The Hunter color's L value in cookies significantly decreased and the a, b values in cookies increased(p<0.05). The hardness of cookies significantly increased added extract from Angelica gigas Nakai increased(p<0.05). The acid value and peroxide value were lower in added Angelica gigas Nakai extract groups than in the control group as the storage period of cookies passed. The results of sensory characteristics demonstrated that 1% added Angelica gigas Nakai extract showed the highest degree of preference among all the items of added Angelica gigas Nakai extract(color, odor, taste, hardness, crispness and overall quality) and the added Angelica gigas Nakai extract indicated possibilities for developments of Angelica gigas Nakai extract cookies.
