The purpose of this study was to evaluate the effects of tetracycline(TC}, flurbiprofen, and PDGF-BB loaded biodegradable membranes on the cell-attachment, the activity of loaded PDGF-BB, in vivo release kinetics, and guided bone regenerative potentials. To evaluate the cell attachment to membranes, the number of gingival fibroblasts attached to each membrane(10% TC, 10% flurbiprofen, $200ng/cm^2$ PDGF-BB loaded membranes, drug-unloaded membrane) was counted by coulter counter and the morphologic pattern of attached cells was examined under SEM. To determine whether the activity of loaded PDGF-BB is sustained, the cellular growth and survival rate of gingival fibroblasts was used for both standard PDGF-BB and loaded PDGF-BB. For evaluation of in vivo release kinetics, drug-loaded membranes were implanted on the dorsal skin of the rats. On 1, 3, 7, 10, 14, 21, and 28 days after implantation, the amount of remaining drugs were measured by HPLC assay for TC and flurbiprofen, and by ${\gamma}-scintillation$ counter for $PDGF-BB^{1125}$. For evaluation of guided regenerative potential, the amount of new bone in the calvarial defect(5mm in diameter) of the rat was measured by histomorphometry 1 and 2 weeks after implantation of membranes. The number of cells attached to the PDGF-BB loaded membrane was largest as compared with the other mernbranes.(p< 0.05) The activity of loaded PDGF-BB was not significantly different from the activity of standard PDGF-BB.(p<0.05) After initial burst release of drug during the first 24 hours, drugs were gradually released for 4 weeks. Especially the release rate of PDGF-BB was nearly constant during 4 weeks. PDGF-BB loaded membranes(200, $400ng/cm^2$) were effective in guided bone regeneration as compared with drug-unloaded membrane. These results implicate that drug-loaded biodegradable membranes might be a useful for guided bone regeneration.

This study evaluated the sanitation management standards for vegetable preparation processes without a cooking stage. The aerobic plate counts (APC), coliform counts, and Escherichia coli of the samples at each production step were analyzed, and microbial growth of the samples stored at different temperatures was measured. The validation was judged in accordance with the microbial criteria stipulated by the British PHLS. After washing and disinfection, the APCs of the two samples decreased to 3∼4 log CFU/g in both seasons. Compared to the purchasing stage, the decrease in coliform counts was approximately 0∼3 log CFU/g in both seasons; E. coli was not detected. The initial APC and coliform levels of two vegetable samples were 4∼ 5 log CFU/g in both seasons, with an increase of 1 log CFU/g taking more than 6 h at 25°C and 2 h at 35°C. More than 10 h at 25°C and 6 h at 35°C were required to increase the E. coli O157:H7 count by 1∼2 log CFU/g for two seasoned samples. In conclusion, washing and disinfection effects and changes in microbial growth during room temperature storage were similar in the two vegetables. Despite the low sanitizing effect of the two vegetables, when cut vegetables were stored under the critical limit within 2 h at two different room temperatures, seasoned lettuce and chicory were at the ‘satisfactory’ or ‘acceptable’ levels of PHLS regardless of the storage temperatures. The validation of sanitation management standards applied to vegetable preparation with the no-cook step was approved.

The purpose of this study was to analyze the relationship between musical interests and empathy ability among middle school students in South Korea. For this purpose, I selected two classes with active and non-active musical activities from different middle schools. The results indicated that there was a high correlation between students ’musical interest and empathy abilities. All areas of musical interest were positively correlated with ‘fantasy’, ‘perspective taking’ and ‘empathic concern’ area of empathy ability. For the ability to empathize, all areas showed a highly positive correlation with the interest in emotional responses to music and interest in music activity areas. Also, there was no significant difference in the overall musical interest and ability to empathize based on the level of music activities between the two types of schools. However, the interests of social interaction through music, musicians and singing activities were higher in the schools with active musical activities.
