This study was conducted to identify how a flexi-bar exercise influences body alignment and balance in adults who have asymmetry in their right or left body. In total, 20 participants were separated into the experimental group and the comparison group. Those in the experimental group participated in a flexi-bar exercise for 6 weeks and based on the coronal plane before and after exercise, their body alignment and balance were measured behind the body. The result was those who had participated in a flexi-bar exercise significantly improved their angle of acromion on both sides, the difference in the angle and height of the posterior superior iliac spine on both sides(p<.05), and the balance of the center sagittal plane(p<.05). Through this study, it could be said that participating in a flexi-bar exercise would improve postural alignment and balance of the shoulder and pelvis in adults with asymmetric posture.

Although whole crop barley are now widely grown as a silage crop in Korea, but silage quality of the whole crop barley produced from farmer's fields have not been published. Therefore, this experiment was conducted to evaluate forage quality of whole crop barley which was participated in Korean quality contest in 2008. These data were classified by region, forage production, added inoculants, planting date and harvest date. Difference on lactic acid of barley silage was detected in the region (p＜0.05), however, there no significant differences in other chemical composition. The moisture and lactic acid were significant differences in dry matter yield of barley silage. There is all the difference between silage added inoculants and control. Differences between planting dates in ash and crude protein (CP) were detected in barley silage (p＜0.05). From comparison within harvest date, lactic acid ㏊d significant differences among barley silage. Differences in forage quality were observed among whole crop barley for silage. Therefore, nutritional quality as well as lactic acid is important in silage quality contest of whole crop barley.

Background : This study was conducted to determine the optimal conditions of growth medium, temperature, and light quality for efficient propagation of Pyrrosia petiolosa spores. Methods and Results : P. petiolosa spores were collected from Andong-si area in February 2015, and the spores were subjected to a careful selection process. The selected spores were stored at the Korea National Wild Plant Seed Bank (4℃, RH 40%) and used as our experimental materials (GR0000182302). The spore germination rate and prothalium development were high in Knop media (24.5%), which had low mineral content. The germination rate increased with the increase in temperature and reached its maximum, 24.5%, at 25°C. The germination rate was also measured under different light conditions, and the highest rate of 28.7% was observed under LED blue light compared to fluorescent lights (24.5%). The germinated spores developed into heart-shaped prothallia under LED blue light; however, 3 weeks after sowing, prothallium development decreased compared to fluorescent lights. Conclusion : In conclusion, the optimal P. petiolosa In vitro propagation method include spore germination on Knop medium at 25°C under LED blue light, and the change in light source to fluorescent light 3 weeks after sowing for prothallium formation and proliferation.

Genetically modified (GM) papaya (Carica papaya L.) line 55-1 (55-1), which is resistant to papaya ringspot virus infection, has been marketed internationally. Many countries such as the European Union, Japan, and Korea have a mandatory safety assessment, approval and labeling regulations for GM foods. Thus, there is a need for specific methods for detecting 55-1. In this study, we established a real-time PCR detection method applicable to 55-1 for a variety of papaya products. The limit of detection was possible for fresh papaya fruit up to dilutions of 0.005% and 0.01% (weight per weight [w/w]) for homozygous SunUp and heterozygous Rainbow cultivars, respectively, in non-GM papaya. The 55-1 event-specific detection method observed parallelism (r2>0.99) between the concentration of line 55-1 cultivars and Ct values obtained in amplification plots at concentrations of 0.005-10% for SunUp DNA and 0.01-10% for Rainbow DNA. The method was applicable to the qualitative detection in various types of processed products (cocktail fruit, dried fruit, juice, etc.) containing papaya as a main ingredient. Monitoring papaya products for the presence of GM papaya were demonstrated using a P35S and T-nos real-time PCR detection method but no amplification signals were detected.
