New technology leads the fast changes to cope with the fourth industrial revolution in the modern society. To meet the changes of the times, not only daily life but also cultural life of the modern people are changing, and these changed the times when we watch the cultural performances such as drama, musical, and opera that we should appreciate onsite into the times to see them whenever and wherever we want to see upon digitalizing them. However, studies have not been actively performed on the performance videos unlike other areas probably since they expect better image quality and services. Hence, considering the expectations from performance video contents by consumers as benefit, convenience, and innovation, this study was conducted to review the effectiveness of these attributes on the trust and satisfaction level. Also, upon reviewing the effectiveness of these on the word of mouth effect, expansion potential of the performance video contents was investigated to deduct the meaningful implications. Study results showed that benefit and convenience affected trust and satisfaction positively while innovation did not affect them at all. Yet, trust and satisfaction showed the positive influence on the word of mouth effect.

In this study, the quality characteristics and antioxidant activities of wet noodles added with seunggumcho (Angelica gigas N Leaf) powder at concentrations of 1, 2, 3, and 4%, respectively, were investigated. The moisture contents and pH of the samples showed a tendency to decrease with increasing amounts of seunggumcho powder. Texture measurement indicated that 'hardness,' 'springiness,' and 'chewiness' of the cooked noodle were the highest in the control group, and these parameters showed a tendency to decrease with increasing amounts of seunggumcho powder. The total polyphenol contents in wet noodles added with seunggumcho powder increased with increasing amounts of seunggumcho powder. 2,2-diphenyl-1-picrylhydrazyl radical scavenging activity was the lowest in the control group (10.85%) and highest in the 4% addition group (44.84%). ${\alpha}-Glucosidase$ inhibitory activity showed the lowest value in control group (1.17%), and increased with increasing amounts of seunggumcho powder. The sensory preference score was the highest for color, flavor, taste, and chewiness in the 2% addition sample. The findings of this study suggest the feasibility of seunggumcho added wet noodles as a health food with physiological benefits and provide evidence for introducing various health foods by adding seunggumcho.

In the era of glocalization, the role of the state is gradually being reduced and the roles of cities and regions are becoming more critical, especially for the everyday life of residents. Many attempts have been made to secure regional competitiveness based on local identity, to differentiate it from other cities and regions, and to search for methods of sustainable development. The importance of place, which affects human life-world, is getting to garner more attention whereas the large-scale development-centered approach has becoming less prominent. The objective of the study is to investigate the concept of place-making and to apply for the East Asian regions, which seems to be differentiated from urban cultural frameworks of the West. The paper employs comparative methodology for the placemaking strategies of the three case locations, say Mok-dong in Seoul, Koganecho in Yokohama and red town in Shanghai. By through examining the three stages of place-making for each three place, it reveals that cultural identity is quintessential in the East-Asian region. In conclusion, it suggests a sustainable place-making strategies for urban areas in East-Asian regional setting.

It is at risk of depletion of biodiversity due to indiscriminate overfishing of ecosystems and destruction of habitats. Intensive fertilizers or development of related facilities to increase agricultural production in poor indigenous areas devastate the soil. Preservation of biodiversity is now emerging as an important issue of global human coexistence. After the Post-2020 GBF Declaration, all governance in agricultural development in indigenous agricultural areas should be supported and promoted as biodiversity conservation measures. A compromise plan to reduce ecosystem development and biodiversity loss can help establish public governance policies. In this paper, a viability kernel used for viable control feedback analysis is introduced to solve conflicting economic and ecological problems in ecosystem conservation, and a mathematical model on biodiversity conservation by the viability kernel is examined. Because all species in the ecosystem are interdependent, if the balance is broken, biodiversity is depleted, which is irreversible and eventually leads to extinction. For sustainable use and harmony of biological resources, a lot of policy consideration is required, such as creative governance that can efficiently protect all species. Subsidies or tax incentives have a direct impact on biodiversity conservation. The recovery of species in a state of decreasing biodiversity can be said to be of great economic value. Biodiversity will allow indigenous producers to be proud of their unique traditional knowledge and have a positive impact on local tourism, thereby enhancing regional identity and greatly contributing to the survival and prosperity of mankind.

This study examined at an exploratory level what should be considered for developing underdeveloped areas using local cultural resources. This study analyzed the psychological and behavioral differences between those who have visited underdeveloped areas developed using local cultural resources and those who haven't, to draw out the implications for the urban regeneration. The results showed that there were differences in respondents' motivation to visit, perception of what needs to be done for the tourism development of underdeveloped areas, perception of the expected effects of developing cultural contents, and consumption behaviors. In other words, those who have visited the tourist sites where had been underdeveloped areas have a more positive attitude toward visit motivations, needs for tourist site development, expected effects of local cultural content development, and consumption behaviors than those who haven't. It means that it is of the utmost importance to induce as many people as possible into tourist sites in underdeveloped areas. This exploratory study is expected to offer some implications for developing underdeveloped areas as tourist sites, a form of urban regeneration.

This study is for major element relationships between ginsengs and soils from three representative soil types from Keumsan, shale, phyllite and granite. In the weathered soils, the granite and phylllite are high while the shale are low. The granite show distinctive positive and negative relationships rather than the phyllite and shale. In the field soils, the granite and phyllite are high while the shale are low. Positive relationships are distinctive with the increasing ages, and in the granite. In the ginsengs, high element contents are shown in K and Na of the shale, Mg and Ca of the phyllite, and Al, Mn and Ti of the granite. In the same regions, the 2 and 3 years are mainly low, but high in the 4 year. Positive correlations are distinctive in the 2 and 4 year of the shale, and 3 year of the granite. Comparisons with ginsengs of the same ages from the different areas suggest that the granite show high element contents with the ages. It also suggests that the 2 year of the granite, and 3 and 4 year of the shale and phyllite are high. Relative ratios(weathered/field soils) among the soils suggest that the weathered are generally high, especially in the granite rather than the shale. Relative ratios between field soils and ginsengs(field soils/ginseng) suggest that the soils are higher than the ginsengs, and differences of several hundred times in the Al and Ti, and of several ten times in the Mn are shown between two. Comparisons among the different ages from the same areas suggest that differences of several hundred times in the Al and Ti are shown. It suggests that ginseng contents are significantly different from the field soils in the Al and Ti contents. Comparisons among from the same ages of the different areas suggest that high element differences are shown in Na of the shale, and Mn of the phyllite, while low element differences are found in Mg of the shale, and Al, Mn, and Na of the granite.

The nutritional compositions and antioxidative activities of the Kimcheon lowbush and Pyungtaek highbush blueberries cultivated in South Korea were investigated. The approximate compositions, pH, and soluble-solid and mineral contents of P, Ca, Mg, Na, and Zn were determined. Both blueberry cultivars had mainly fructose and glucose as free sugars while disaccharides such as sucrose, maltose, and lactose were not detected in both. Oleic, linoleic, and linolenic fatty acids were the major fatty acids in both types of blueberries. The total of 16 free amino acids, including seven essential and nine non-essential amino acids, were higher in the Pyungtaek highbush blueberry. Among the amino acids, arginine was especially much higher in the Pyungtaek highbush blueberry. The anthocyanin, resveratrol, and polyphenol compounds, which are the important biologically active compounds in blueberries, were found. The anthocyanin contents of the Kimcheon lowbush and Pyungtaek highbush blueberries were 22.0 and 18.1 mg/100 g, respectively; the resveratrol contents by HPLC, 0.12 and 0.11 mg/100 g; and the total polyphenol contents, 141.3 and 138.4 mg/100 g. The electron-donating ability determined based on the DPPH radical scavenging activity was increased in a concentration-dependent manner, and it was higher than that of the Pyungtaek highbush blueberries, which implies that it is highly correlated with the higher amounts of total polyphenol, anthocyanin, and resveratrol in it. In conclusion, the two varieties of Korean blueberries can be suggested as potential sources of high-value-added functional foods.

In this study, the Bodhi tree powder is used as an additive to Seolgi rice cake and the research is made how useful the additives are to the Seolgi rice cake. This research would be a good way to develop and distribute the Seolgi rice cake which is added with the powder of Bodhi tree. The results of the study are as follows. 1. The water contents of Bodhi tree was 81.64% with 1.75% of crude protein, 0.81% of crude fat, and 0.56% of crude ash. It was found out that the Bodhi tree has higher contents of polypherol and has the efficacy of anti-oxidation property and has the value as the food stuff. 2. When the Seolgi rice cake is made with the addition of Bodhi tree powder, the value of a and b, sugar, hardness, elasticity, texture and viscosity have risen while the contents of water, L value, pH, stickiness and cohesiveness were lowered. The property test showed that the addition of Bodhi tree to Seolgi rick cake would make all testing items "strong" and the addition of 4% of Bodhi tree in the manufacturing of Seolgi rice cake was most preferred. 3. As for the storage of Seolgi rice cake is concerned, as the period of storage goes by, the value a and b, hardness, elasticity and texture and viscosity have increased while the water contents, L value, stickiness and cohesiveness have reduced. As the period of storage gets longer, the total cell number has increased. But as the more volume of Bodhi tree is added to the rice cake, the total cell number has reduced, thus lengthening the storage period. The rest shows that in producing the Seolgi rice cake, the 4% of addition of Bodhi rice cake is deemed to be the best. It was confirmed that the proper volume of Bodhi powder is proper for the Seolgi rice cake and is also good for decorative and quality characteristics for the rice cake.
