South Korea’s successful education system: lessons and policy implications for Peru
Elizabeth Bermeo 한국사회과학협의회 2014 Korean Social Science Journal Vol.41 No.2
South Korea’s quality education system rests on four pillars: (1) putting edu-cation at the center of a long-term development strategy, (2) getting the right people tobecome teachers, (3) developing these people into effective instructors, and (4) prioritizinginformation and communications technology in education. In contrast, education policiesin Peru change from government to government, official evaluations of teacher educationinstitutes do not exist, teachers do not receive regular training, and the use of technology ineducation is limited. Taking into account South Korea’s successful experience, Peru couldseek to improve its education system with initiatives to support a long-term educationpolicy, which has to include a clear plan to improve the accreditation process of teachereducation institutes, the current salaries of teachers, the training of teachers, and the use oftechnology in schools.
What determines international tourist arrivals to Peru? A gravity approach
Maritza Elizabeth Bermeo Velasquez,오진환 한국외국어대학교 국제지역연구센터 2013 International Area Studies Review Vol.16 No.4
Using the gravity model, this study examines Peru’s tourism patterns by analyzing a panel dataset of the country’s international tourism flows from 59 countries over 22 years (1990–2011). The empirical results for the entire dataset are consistent with the general prediction of the gravity model (positive coefficients for economic size and negative coefficients for distance). Peru mainly has potential to expand tourism flows from E uropean countries like Portugal, Belgium,Russia, Norway, Sweden, Switzerland, Italy, Germany and France. Although Peru offers no visa requirements for such countries, this policy seems to not be sufficient to increase tourism flows from them. Further collaboration between Peru and its neighboring countries in providing coordinated investment in transport infrastructure is necessary to create economies of scale that allow benefits from the cluster effect.
Academic Environment in the University ; Key to the Mathematical Talent
( Nunez Reinaldo ),( Gomez Bermeo Laura ) 한국수학교육학회 2011 수학교육 학술지 Vol.2011 No.-
The University Sergio Arboleda develops the program of mathematical talents directed to children and youngsters of the basic and intermediate education. One of the conditions of the program is that the students develop the academic activities in the University; the most out-standing students are promoted to taking courses of the undergraduate program in mathematics. During 9 years of experience in the program we have observed that the academic environment of the university has been a positive factor in the motivation, the promotion and development of the talent and has had a favorable influence in the familiar and school environments of the students.
The Effect of Antidepressants on Mesenchymal Stem Cell Differentiation
Jeffrey S. Kruk,Sandra Bermeo,Kristen K. Skarratt,Stephen J. Fuller,Gustavo Duque 대한골대사학회 2018 대한골대사학회지 Vol.25 No.1
Background: Use of antidepressant medications has been linked to detrimental impacts on bone mineral density and osteoporosis; however, the cellular basis behind these observations remains poorly understood. The effect does not appear to be homogeneous across the whole class of drugs and may be linked to affinity for the serotonin transporter system. In this study, we hypothesized that antidepressants have a class- and dosedependent effect on mesenchymal stem cell (MSC) differentiation, which may affect bone metabolism. Methods: Human MSCs (hMSCs) were committed to differentiate when either adipogenic or osteogenic media is added, supplemented with five increasing concentrations of amitriptyline (0.001-10 μM), venlafaxine (0.01-25 μM), or fluoxetine (0.001-10 μM). Alizarin red staining (mineralization), alkaline phosphatase (osteoblastogenesis), and oil red O (adipogenesis) assays were performed at timed intervals. In addition, cell viability was assessed using a 3-(4,5-dimethylthiazol-2-yl)-2,5-diphenyl- 2H-tetrazolium bromide-formazan assay. Results: We found that fluoxetine had a significant inhibitory effect on mineralization. Furthermore, adipogenic differentiation of hMSC was affected by the addition of amitriptyline, venlafaxine, and fluoxetine to the media. Finally, none of the tested medications significantly affected cell survival. Conclusions: This study shows a divergent effect of three antidepressants on hMSC differentiation, which appears to be independent of class and dose. As fluoxetine and amitriptyline, but not venlafaxine, were affected both osteoblastogenesis and adipogenesis, this inhibitory effect could be associated to the high affinity of fluoxetine to the serotonin transporter system.
