Externally, there is urgent need Strengthening the competitiveness of agriculture in terms of production, processing and consumption. And development of high-quality services is particularly essential for provide safe food to consumers, internally. We studied the concept of service science, service models and service development methodology, then researched strengthening agricultural competitiveness through analysis of service viewpoint. After then, in the service level and service science, we elicit the service components for the defined new business, which is composed of private service and supporting service for Mungyeong omija industry. In this research, we evaluate the possibilities that agriculture is not primary industries but service industries for competitiveness. We suggest four key service composition for win-win strategy in Mungyeong omija industry. That is authenticity service, decision price service, decision rating service, establish infrastructure for year-round sale.

This study was conducted to ferment high quality vinegar by using Omija fruit. Strains of bacteria producing acetic acid were isolated from spoiled Omija wine (OV1 and OV2) and traditional rice vinegar (RA). The bacterium was from optimally-oxidized Omija wine containing 6.0% ethanol and from Omija vinegar with 5.21% acetic acid by 14 days of fermentation. The Omija vinegar got the highest sensory score (5.80) among several commercial vinegars. The Omija vinegar showed a potent antibacterial activity against Staphylococcus aureus, Bacillus subtilis, Escherichia coli, and Pseudomonas fluorescens by the paper disc test, while Omija wine had limited antibacterial activity against S. aureus and P. fluorescens. The diameter of the clear zone formed by the paper disc test using Omija vinegar was not less than 9.5 mm. The DPPH free radical-scavenging activity of Omija wine was higher than that from Omija water extracts. The nitrite scavenging ability of Omija wine (36.98% of all nitrites present) and vinegar (31.14%) was higher than that from Omija water extracts (22.53%). Omija vinegar exhibited strong antibacterial and antioxidant activities. In conclusion, we prepared high quality vinegar from dried Omija.

Extracts from Schizandra chinensis Baillon (Korean name: Omija) were tested for antioxidant and their inhibitory activities of ${\alpha}-amylase$ and ${\alpha}-glucosidase$. Total contents of phenolics were found as 4.35 mg/g (water extract)${\sim}$6.35 mg/g (60% ethanol extract). Electron donating ability (EDA), ABTS [2,2'-azinobis(3-ethyl-benzothiaznoline-6-sulfonic acid)] radical decolorization, antioxidant protection factor (PF) and thiobarbituric acid reactive substance (TBARS) were measured for the antioxidative activity of the extracts from S. chinensis. The water extract were determined as 97.5% at 200 ${\mu}g/ml$ while the activity of 60% ethanol extract were 96.2% at 200 ${\mu}g/ml$ in EDA. The 60% ethanol extract showed higher antioxidant activity than water extract when evaluated by ABTS radical decolorization, antioxidant PF and TBARS. ${\alpha}-Amylase$ inhibitory activity of water extract was similar with that of 60% EtOH extract. ${\alpha}-glucosidase$ inhibitory activities of water extract (97.4%) was higher than that of 60% ethanol extract (84.5%) at 200 ${\mu}g$/ml. The water extract from S. chinensis did not show an antimicrobial activity against Helicobacter pylori, but the 60% ethanol extract showed high antimicrobial activities such as 23 ${\pm}$ 1.6 mm of clear zone in 200 ${\mu}g/ml$ of phenolics. The result suggest that the water and 60% ethanol extract from S. chinensis will be useful as natural antioxidants and functional foods.

To find the optimum extraction condition of dried omija, central composite experimental design having three independent variable (extraction temperature, extraction time and water ratio) with five levels was conducted for response surface analysis. The maximum of soluble solid was predicted to the extraction conditions of over 25 fold water ratio, $7{\sim}8hr$ and $75^{\circ}C$. Total acid, total phenol, reducing sugar and vitamin C were predicted to respectively 30 fold water ratio, 6 hr, $70^{\circ}C$, 30 fold water ratio, $6{\sim}7\;hrs,\;80^{\circ}C$ and 30 fold water ratio, $6{\sim}8\;hr,\;80^{\circ}C$, 25 fold water ratio, $5{\sim}6hr,\;80^{\circ}C$ extraction condition. Turbidity of extraction condition. Turbidity of extraction condition was 7 over 25 ford water ratio and over $60^{\circ}C$. From the superimposing results of response variables, the optimum extraction condition was predicted 25 folds water ratio, 6 hr and $65{\sim}70^{\circ}C$.

This study made use of 9 types of utilizing idle farmland deducted from existing research in order to examine cases by type of idle farmland, and selected representative cases by type after analyzing contents of 165 available newspaper articles. Selected Cases were assorted into agricultural use and nonagricultural use, and agricultural use are as followed. (1)Community Service/Farming type is the case of Gimhae city reported on 'Busan Ilbo', (2)High Income/Farming type is the case of cooperative unit of Geumjeong crude drug in Yeongam appeared in 'Newsis', and the case of Omija industry in Mungyeong reported on 'Hankyoreh', (3)Tourism/Landscape/Farming type is the case of rape flowers and buckwheat flowers in Gupo village reported on 'Asia News Agency', (4)Stock Raising/Farming type is the case of growing foraging crops published in 'The Daejeon Ilbo', (5)Weekend farm type is the case of utilizing idle farmlands and creating weekend farm reported on 'Mediawatch', (6)High income/Forest type is creating Mulberry cultivation areas in Hamyang-Gun published in 'Yonhap News', (7)Ecology/Landscape/Forest type is forestation project of idle land reported on 'Newsis', (8)Agricultural Experience Study type is the case of managing agricultural experience study center in Dosun elementary center published in 'Sisajeju' and the case of non-agricultural application case, (9)Ecological Environment type is the case of wetland restoration of idle farmland in Gochang. This study investigated and arranged detailed contents by the literature search and interview investigation according to investigating items such as utilizing area, main agent, purpose, utilizing item, utilizing content, etc. by case. With that, it deducted implications as well as case characteristics, and finally suggested political proposals through the case analysis.
