For the development of high value consumables utilizing jujube and grape, we investigated the biological activities of a variety of existing fermentation products of jujube and grape. The results revealed that ethanol fermentation products of jujube and grape had a higher antioxidative activity than acetic acid fermentation products. In addition, the ethanol fermentation products of jujube (JEF) had the highest antioxidative activity, with it being greater than that of the ethanol fermentation products of grape (GEF), the acetic acid fermentation products of jujube (JAF) and the acetic acid fermentation products of grape (GAF). As regards tests on whitening effects, JEF exhibited the highest tyrosinase inhibition effects amongst the test groups. However, when immunofluorecence was employed, JAF was seen to inhibit the expression of proteins related to the whitening effect. In the lipopolysaccharide-stimulated mode peritoneal macrophage model, all tested groups of fermentation products (JEF, GEF, JAF and GAF) suppressed nitric oxide production dose-dependently, with ethanol fermentation products demonstrating a higher nitric oxide expression inhibition effect than acetic acid fermentation products. When subjected to antibacterial activity tests, GAF exhibited antibacterial activity against all tested strains except Propionibacterium acnes. Both GAF and JEF revealed high antibacterial activity against Escherichia coli.

This study attempted to propose a space planning of rural villages having been connected by small-regions units as a plan of regional economic growth through cultivating native resources located in rural areas and then developing them. As research methods, this study carried out literature research and empirical study at the same time, and then was progressed to directions of deducing a basic plan by applying alternatives to actual object sites based on the results. Endogenous developments of areas through native resources' developments have been emphasized in Korea recently, and various policies and strategies are being appeared for making regional economic growth under these recognitions. However, rural village planning has directed to physical maintenances centering on functionality till now, and composed of facility repairs and experience projects of urban-rural interchanges mostly so as to solve living environments between cities and agricultural villages. Therefore, this study intended to pose discrimination with existing rural village planning, and set up a growth plan of rural villages by cultivating and developing tangible and intangible native resources having been kept in the rural villages and then commercializing them centering on indigenous native resources.
