Background: Panax ginseng Meyer polysaccharides exhibit various biological functions, like antagonizing galectin-3-mediated cell adhesion and migration. Galectin-8 (Gal-8), with its linker-joined N- and C-terminal carbohydrate recognition domains (CRDs), is also crucial to these biological processes, and thus plays a role in various pathological disorders. Yet the effect of ginseng-derived polysaccharides in modulating Gal-8 function has remained unclear. Methods: P. ginseng-derived pectin was chromatographically isolated and enzymatically digested to obtain a series of polysaccharides. Biolayer Interferometry (BLI) quantified their binding affinity to Gal-8, and their inhibitory effects on Gal-8 was assessed by hemagglutination, cell migration and T-cell apoptosis. Results: Our ginseng-derived pectin polysaccharides consist mostly of rhamnogalacturonan-I (RG-I) and homogalacturonan (HG). BLI shows that Gal-8 binding rests primarily in RG-I and its β-1,4-galactan side chains, with sub-micromolar K_D values. Both N- and C-terminal Gal-8 CRDs bind RG-I, with binding correlated with Gal-8-mediated function. Conclusion: P. ginseng RG-I pectin β-1,4-galactan side chains are crucial to binding Gal-8 and antagonizing its function. This study enhances our understanding of galectin-sugar interactions, information that may be used in the development of pharmaceutical agents targeting Gal-8.

The purpose of this study was to analyze the current status and contents of color-related education programs as lifelong education and to determine the necessity of color education and directions for future development. The findings of this study, first show that the general welfare center, which is striving to develop abilities and promote welfare, was opened mainly for professional education, rather than hobby-oriented education. Accordingly, pricing was set at a lower level than the three institutions and centers, but without a variety of programs or hobby-oriented courses. Second, as the purpose of the set-up is to be established, the general welfare center should be considered an area for hobbies along with expertise, and various courses should be opened. Although the department store's cultural center focused on programs for cultural and leisure use and promotion, it is necessary to extend the program to attempt to approach it in a short-term process rather than a one-time class. The lifelong education center established as a subsidiary of the university' was opened as an area for of painting such as oil painting and watercolor and drawing which have much in common school should learn and start basic theory and practice, so there was much difference. Third, if it is changed to a developed form of color-oriented education according to the purpose of each center and institution presented in the results of this research, a good response will be possible to further improve the quality of life and develop professionalism and creativity.

Objectives: Parents of a premature baby feel a pressure on their baby's growth and they are highly in need for proper education. However, the lack of proper education can cause the difficulty of follow-up care and rehospitalization. Currently, methods of education among each nurse are based on verbal explanation and can be often different. Therfore, it is true that the psychological burden is great during education. Hence, by enforcing discharge education activities, we intend to provide information; induce participation of parents; promote the level of performance; standardize education program; and increase the job satisfaction of nurses. Methods: NICU conducted a questionnaire survey of the demand and satisfaction for discharge education among mothers that left hospital. And before and after the improvement activity, the satisfaction level of mothers and nurses were studied, and rehospitalization rate were analyzed. Results 1)The survey results of the satisfaction level of mothers towards education program as followes: The level of understanding of content, general babysitting, special situation, education method, and educator attitude showed statistically significant increase. 2)The survey results of the satisfaction level of nurses towards education program as followes: While, the need for education program decreased, the adequacy of education content and method, consistency of education, understanding of learner, and learner's performance increased. All the factors except for the need for education program and the adequacy of education content showed statistically significant difference. 3)Rehospitalization rate of premature babies decreased. According to analysis of the cause of rehospitalization, breast-feeding related apnea turned out to be the highest. Conclusion: Through QI, satisfaction of mothers and nurses improved more than 10%. And rehospitalization rate of premature babies decreased by the same amount as well. Therefore, with the help of the standardized discharge education program, mothers who is not easy to take care of after leaving hospital can be seen to significantly affect their healthy growth and development.

Microalgae hold promise as a renewable energy source for the production of biofuel, as they can convert light energy into chemical energy through photosynthesis. However, cost-efficient harvest of microalgae remains a major challenge to commercial-scale algal biofuel production. We first investigated the potential of electrolytic water as a flocculant for harvesting Tetraselmis sp. Alkaline electrolyzed water (AEW) is produced at the cathode through water electrolysis. It contains mineral ions such as $Na^+$, $K^+$, $Ca^{2+}$, and $Mg^{2+}$ that can act as flocculants. The flocculation activity with AEW was evaluated via culture density, AEW concentration, medium pH, settling time, and ionic strength analyses. The flocculation efficiency was 88.7% at 20% AEW (pH 8, 10 min) with a biomass concentration of 2 g/l. The initial biomass concentration and medium pH had significant influences on the flocculation activity of AEW. A viability test of flocculated microalgal cells was conducted using Evans blue stain, and the cells appeared intact. Furthermore, the growth rate of Tetraselmis sp. in recycled flocculation medium was similar to the growth rate in fresh F/2 medium. Our results suggested that AEW flocculation could be a very useful and affordable methodology for fresh biomass harvesting with environmentally friendly easy operation in part of the algal biofuel production process.
