The purpose of this study was to determine antioxidant and physiological activities of water and 70% ethanol extracts from Ligularia fischeri by extraction methods. The yield of water and ethanol extracts from Ligularia fischeri was 15.23% and 17.45%, respectively. The polyphenol and flavonoid contents of ethanol extracts of Ligularia fischeri (LEE) were $17.17{\pm}4.38mg/g$, $35.06{\pm}6.69mg/g$, respectively. The electron donating ability and SOD like activity, and ABTS radical ability of all Ligularia fischeri extracts were increased in a dose dependent manner, and those was the highest in LEE. Nitrite scavenging ability was higher in pH 1.2 than that in pH 3.0, and ethanol extract showed higher ability in pH 1.2 and 3.0. The xanthine oxidase and inhibition effect of all Ligularia fischeri extracts on tyrosinase were dose-dependently increased, and those was the highest in ethanol extracts of Ligularia fischeri. Reducing power was 1.2 at extract concentration $1,000{\mu}g/mL$ in water and ethanol extracts of Ligularia fischeri and the highest in water extract of Ligularia fischeri at concentration of $62.5-500{\mu}g/mL$. These results may contribute to development of processed food and health functional food with Ligularia fischeri.

This study is performed to light up the semiotic system of streetscape in the harbor on the basic concept of all cultural phenomena that could be described as a Semiotic System. The semiotic approach to landscape analysis was used for understanding landscape characteristics owing to implication of psychological process. Streets of the study were located at Ganguri and Opori on Gang-Gu Harbor and the signboard semiotics of streets were divided into 17 meanings according to the business category. The analysis of this category was applicable on semiotic meaning. The research results are as follows: First, the main part of the business category was food. 56.3% of Ganguri and 61.8% of Opori had the name of food businesses. Second, the semiotic characteristics of Gang-Gu harbor streets mainly mean place name or friendly name. The food business could be related to the principal products of this district which are called Young-Duk Great Crab. Also, the place name could be from symbolic meaning of the crab and the friendly name could be connected with increasing the sales. Finally, the semiotic approach to landscape does not fully cover the streetscape but could be useful for understanding a skeleton of harbor streetscape.

The present research explores the tendency of the items that require Place Location Knowledge (PLK) of the Korean Geography subject in the College Scholastic Ability Test. The major findings are as follows. First, the geographical regions of the items are spatially skewed, especially in the Yeongnam regions, which are tested more frequently compared to the others. Second, the fact-based items more concern with regionality such as geographic indication system and regional festivals. Third, the concept-based items can be divided into physical geography and human geography and there were four items related to economic geography. Fourth, students tend to find it challenging in the items asking PLK. The difficulty varies according to the type of items. The students find concept-based items which require high-order thinking more challenging. There is also differences identified between contents. For example, the section of physical geography, especially climatology-related, were considered the most challenging followed by those of economic geography. Finally, the differences in the rate of correct answer are associated with the scale of the regions covered in the items and students experienced more difficulty in the items asking more precise scale.

This study was to estimate the economic value of Gaecheon Arts Festival in Jinju, Korea. To measure the value of the festival, improved travel cost measurement that applied new weight concept from the Travel Cost Measurement(TCM) proposed by Peares(1972) was used. The total value was evaluated to approximately 2,270.057 billion KRW. The result showed that travel cost items affecting on economic value of the festival were transportation, food and beverage, shopping, accommodation, amusement and entrance fee in order. The effect of accommodation due to the visitors' surplus was small, due to day trip participation trend??. Because accommodation, shopping and entrance fee, therefore, directly affect the regional economy, it is necessary for festival planning party to develop the program for tourist accommodation and so forth. Finally, this study will contribute to the development of local festivals through the more objective, clear comparison and measurement of economic value between local festivals using improved travel cost estimation method.

TheCitrus grandis Osbeck is a special product in the Jeju island. The product has been as a remedy for liver damage and hang over. This study demonstrates how to investigate and compare the antioxidant, phenol content, tyrosinase and ${\alpha}$-glucosidase inhibitory activity, antimicrobial, and alcohol dehydrogenase (ADH) and acetaldehyde dehydrogenase (ALDH) activity with the C. grandis leaves extracted in different ethanol concentrations. From the yield, a 20% ethanol extract demonstrated the highest results among the other extracts. The distilled water extract showed the most abundant in a total phenol content and highest ABTS radical scavenging activity and reducing power assay. In the DPPH radical scavenging activity, ${\alpha}$-glucosidase and tyrosinase inhibitory assay (used ${\text\tiny{L}}$-tyrosine as substrate), the 80% ethanol extract exhibited a higher value than other extracts. The 60% ethanol extract showed prominent activities in the tyrosinase inhibitory (used ${\text\tiny{L}}$-dopa as substrate), ADH and ALDH activity assay. In the minimum inhibitory concentration (MIC) assay, 60% and 80% ethanol extracts inhibited the bacterial growth almost similarly. Moreover, the gram-positive bacteria was more restrained than the gram-negative bacteria. The resultsrevealed that the distilled water and 80% ethanol extract showed a relatively higher antioxidant activity compared to other extracts. The 60 ~ 80% ethanol extracts demonstrated potential tyrosinase, ${\alpha}$-glucosidase inhibitory, antimicrobial, ADH and ALDH activities. Therefore, the C. grandis is suggested to be considered as a functional material for various proposes.

The purpose of this study was to optimize dough properties using response surface methodology (RSM) and to demonstrate the performances of dough prepared under optimized conditions. Dough mixed with yeast, margarine, salt, sugar and wheat flour was prepared by fermentation process. Hardness, cohesiveness and springiness of dough were selected as critical quality attributes. The critical formulations (yeast and water) and process (fermentation time) variables were selected as critical input variables based on preliminary experiment. Box-Behnken design (BBD) was used as RSM. As a result, the quardratic, the squared and the linear model respectively provided the most appropriate fit ($R^2$>90) and had no significant lack of fit (p>0.05) on critical quality attributes (hardness, cohesiveness and springiness). The accurate prediction of dough characteristics was possible from the selected models. It was confirmed by validation that a good correlation was obtained between the actual and predicted values. In conclusion, the methodologies using RSM in this study might be applicable to the optimization of fermented foods containing various wheat flour and yeast.

Presenting symbolic concepts consistent with the culture of the host country and international trends at international events will win the favor of the world and raise the image of the host country. The international event mascot symbolically represents the host country's unique culture, and is a good means to enhance the sense of belonging and pride of its members and to display the image of the host country in an outwardly. This study discussed the symbolic elements of the host country characteristics reflected in FIFA's World Cup event mascot. A total of 14 mascots of World Cup events were held from 1966 to 2018, and their materials can be divided into animals, plants, people and creations. The mascot was applied with the characteristic elements of regional specialties, the flag of the host country, symbolic attire, language of the hosting area, social issues and the mascot's dress, posture, props and expression characters of soccer events were used as symbolic elements. First of all, the implications of the research were that mascots were more strongly expressing the "football" signifying element, the theme of events, rather than regional characteristics. Second, the use of 'national flag' was highlighted among the elements of expressing regional characteristics. Third, 'animal' was preferred for mascot material. Fourth, mascots have become integrated with 'cultural perfumes' and play an extended role in raising social awareness. Implications derived from the classification of characteristics and symbol representation elements raised in this study will be used as a basis for the planning of international event mascots.
