This study aimis to identify policy priorities for promoting youth activities through the Importance-Performance Analysis (IPA). IPA is used to identify policy priorities for promoting local youth activities. The IPA tabulated result is presented in a two-dimensional grid to showing for promoting local youth activities, The require concentrate support part is divided into 3 parts. Problem solve supporting at work development of leisure activities programs, leisure activities programs developing and development of leisure-related professionals. And leisure-related professionals developing. The next parts that require continuous management were divided into four parts. The next parts that require continuous management is divided into four parts. Creating rental housing for young people, support for housing expenses supporting, loans supporting, and Holiday guaranteed. Based on the factors that support youth activities that make up the IPA matrix, the implications of revitalizing local youth activities is presented as below. First, ensuring employment of local youth and efforts to create sustainable jobs. Second, continuous efforts to improve the housing conditions of local youth, and third, policy support is needed for local youth to do various leisure activities.

This study was performed to investigate the quality characteristics of Yanggaeng, including color, pH, total polyphenol contents, and antioxidant activities, with the addition of aged garlic extract (0, 3, 6, 9 or 12%), aged at low temperatures. Among the color characteristics, the lightness value decreased, and the redness and yellowness values increased, proportional to the amount of garlic extract concentrate added to Yanggaeng. The pH of Yanggaeng significantly (p<0.05) decreased according to the amount of aged garlic extract added. Total phenol contents of control (0% aged garlic extract added Yanggaeng) was the lowest, followed by 3, 6, 9, 12% aged garlic extract added to Yanggaeng (88.15, 118.39, 156.91, 208.79 mg/g, respectively). Antioxidant activities, such as DPPH and ABTS radical scavenging activity, significantly increased with increase in the aged garlic extract concentration. In the sensory evaluation for Yanggaeng, 6% aged garlic extract added to Yanggaeng had the highest score in taste, flavor, and overall acceptance. Based on these results, it is suggest that the addition of 6% aged garlic extract to Yanggaeng can be developed as a product for the elderly.

Objective: Cows that are nursing get around 80% of their glucose from liver gluconeogenesis. Propionate, a significant precursor of liver gluconeogenesis, can regulate the key genes involved in hepatic gluconeogenesis expression, but its precise effects on the activity of enzymes have not yet been fully elucidated. Therefore, the aim of this study was to investigate the effects of propionate on the activity, gene expression, and protein abundance of the key enzymes involved in the gluconeogenesis of dairy cow hepatocytes. Methods: The hepatocytes were cultured and treated with various concentrations of sodium propionate (0, 1.25, 2.50, 3.75, and 5.00 mM) for 12 h. Glucose content in the culture media was determined by an enzymatic coloring method. The activities of gluconeogenesis related enzymes were determined by enzyme linked immunosorbent assay kits, and the levels of gene expression and protein abundance of the enzymes were detected by real-time quantitative polymerase chain reaction and Western blot, respectively. Results: Propionate supplementation considerably increased the amount of glucose in the culture medium compared to the control (p<0.05); while there was no discernible difference among the various treatment concentrations (p>0.05). The activities of cytoplasmic phosphoenolpyruvate carboxylase (PEPCK1), mitochondrial phosphoenolpyruvate carboxylase (PEPCK2), pyruvate carboxylase (PC), and glucose-6-phosphatase (G6PC) were increased with the addition of 2.50 and 3.75 mM propionate; the gene expressions and protein abundances of PEPCK1, PEPCK2, PC, and G6PC were increased by 3.75 mM propionate addition. Conclusion: Propionate encouraged glucose synthesis in bovine hepatocytes, and 3.75 mM propionate directly increased the activities, gene expressions and protein abundances of PC, PEPCK1, PEPCK2, and G6PC in bovine hepatocytes, providing a theoretical basis of propionate-regulating gluconeogenesis in bovine hepatocytes.

Recent landscape changes from human activities, such as agricultural development and urbanisation frequently result in the loss of habitats, the reduction in habitat patch size and an increasing isolation of habitat patches. However, there is little information on woodland changes in agricultural landscapes. Therefore, the aim of this research was to assess spatial characteristics and changes of woodland in an agricultural landscape and how these may have had an impact on ecological process for 33 years. One of the agricultural landscape character units was analysed based on aerial photographs from 1976, 1983, 1994, 2002 and 2009 in Gwangju city. The results indicated that landscape ecological metrics clearly showed that they could be used to monitor changes of woodland ecological conditions during the past 33 years. The results imply that particularly human activities have been leading to the decrease of the mean size of woodland patches and finally result in woodland isolation. These changes may have a negative impact on woodland bird species in the study area. This woodland information can be used to identify the potential and specific needs for setting priorities for conservation planning.

This study examined the mechanisms underlying the effects of the vasorelaxation active substance(VAS), dimethyladenosine-5'-L-arabinose, and its partial purification fraction on nitric oxide synthase in improving erectile dysfunction with particular focus on the nitric oxide (NO)-cGMP pathways. Two rat models, 9-month-old SD rats and 11-month-old SD rats, were given VAS(40 mg/kg per day) for 4 days, The aqueous fraction of silworm male pupae extract; semi-purified VAS(100 mg/kg per day) for 10 days, respectively. The NOS activities of the following three enzymes were examined: neuronal NO synthase(nNOS), inducible NOS(iNOS), endothelial NOS(eNOS), vascular endothelial growth factor on endothelial cells(VEGF) and anti-inflammation effect of Tumor necrosis factor-$\alpha$. The results showed increases in the nitric oxide synthase activities. Western blotting of the tissue homogenate showed an increase in the nNOS level in the brain and tongue, and an increase in the endothelial NO synthase(eNOS) level in penis. However, there was little association with VEGF production in HUVEC endothelial cells and no relationship with TNF-$\alpha$ which showed low levels.

Under the WTO, Bang-Wha country's agriculture is experiencing many difficulties and environmental changes. For overcoming this situation, some agricultural development strategy should be established in Bong-Wha county. First, special agricultural products adapt to local condition should be produced. Second, innovation technics should be developed in local agriculture. Third, marketing activities should be improved in local agricultural products. Finally, organic agricultural products' development should be activated.
