Estimates of Total Factor Productivity, the Contribution of ICT, and Resource Reallocation Effects in Japan and Korea

The purpose of our study is to identify the sources of economic growth based on a KLEMS model for Japan and Korea. We also identify the growth contribution of ICT assets and resource reallocation effects in the two economies. Both Japan and Korea enjoyed high TFP growth in ICT-producing sectors but suffered low TFP growth in ICT-using sectors. For Japan, we find that the main factor underlying the Lost Decade is the slow-down in TFP growth. We also found that Korea's TFP growth was slow until the Asian financial crisis of 1997-1999 but then accelerated after the crisis. It seems that before the crisis, Korea was following a catch-up process with developed economies that was predominantly input-led and manufacturing-based, as documented by Timmer (1999) and Pyo (2001). However, through the drastic economic reform undertaken during the crisis, Korea seems to have shifted to a new phase of economic growth since the end of the 1990s. TFP growth rates, especially those in manufacturing sectors, have substantially increased in post-crisis Korea. Both in Japan and Korea, productivity in service sectors is much lower than in manufacturing. The reason probably is excessive regulation and a lack of competition in service sectors. And these factors seem to have impeded introduction of ICT in service industries. As for ICT capital accumulation, the ICT investment/GDP ratio of Korea is higher than that of Japan. Especially, the speed of ICT accumulation in the ICT sector in Korea is much faster than that in Japan. Both in Japan and Korea, the largest component in ICT investment is computing equipment. In the case of resource reallocation across sectors, the reallocation effect of capital input was negligible or negative for most periods both in Korea and Japan. After the financial crisis of 1997-99, the resource allocation effect of capital in Korea remained negative, although the size of the negative effect declined. On the other hand, the reallocation effect of labor input was positive for most periods both in Korea and Japan.

Discutindo a educação ambiental no cotidiano escolar: desenvolvimento de projetos na escola formação inicial e continuada de professores

A presente pesquisa buscou discutir como a Educação Ambiental (EA) vem sendo trabalhada, no Ensino Fundamental e como os docentes desta escola compreendem e vem inserindo a EA no cotidiano escolar., em uma escola estadual do município de Tangará da Serra/MT, Brasil. Para tanto, realizou-se entrevistas com os professores que fazem parte de um projeto interdisciplinar de EA na escola pesquisada. Verificou-se que o projeto da escola não vem conseguindo alcançar os objetivos propostos por: desconhecimento do mesmo, pelos professores; formação deficiente dos professores, não entendimento da EA como processo de ensino-aprendizagem, falta de recursos didáticos, planejamento inadequado das atividades. A partir dessa constatação, procurou-se debater a impossibilidade de tratar do tema fora do trabalho interdisciplinar, bem como, e principalmente, a importância de um estudo mais aprofundado de EA, vinculando teoria e prática, tanto na formação docente, como em projetos escolares, a fim de fugir do tradicional vínculo “EA e ecologia, lixo e horta”.Facultad de Humanidades y Ciencias de la Educació

Total Factor Productivity in Korea and International Comparison- Data Structure and Productivity Estimates of Korea Industrial Productivity Database

The purpose of our study is to identify the sources of economic growth for the Republic of Korea, which experienced a financial crisis in 1997 after joining OECD. We report estimates of output, input, and productivity based on the newly constructed Korea Industrial Productivity (KIP) database following EU KLEMS project guidelines. We find that Korea’s catch-up process with industrial nations in its late industrialization has been predominantly input-led and manufacturing-based. However, since its financial crisis in December 1997, the sources of growth seem to have switched to productivity-growth based. But lower productivity in service industries seems to work against finding renewed sustainable growth path

DNA Methylation Profiles of Blood Cells Are Distinct between Early-Onset Obese and Control Individuals

Obesity is a highly prevalent, chronic disorder that has been increasing in incidence in young patients. Both epigenetic and genetic aberrations may play a role in the pathogenesis of obesity. Therefore, in-depth epigenomic and genomic analyses will advance our understanding of the detailed molecular mechanisms underlying obesity and aid in the selection of potential biomarkers for obesity in youth. Here, we performed microarray-based DNA methylation and gene expression profiling of peripheral white blood cells obtained from six young, obese individuals and six healthy controls. We observed that the hierarchical clustering of DNA methylation, but not gene expression, clearly segregates the obese individuals from the controls, suggesting that the metabolic disturbance that occurs as a result of obesity at a young age may affect the DNA methylation of peripheral blood cells without accompanying transcriptional changes. To examine the genome-wide differences in the DNA methylation profiles of young obese and control individuals, we identified differentially methylated CpG sites and investigated their genomic and epigenomic contexts. The aberrant DNA methylation patterns in obese individuals can be summarized as relative gains and losses of DNA methylation in gene promoters and gene bodies, respectively. We also observed that the CpG islands of obese individuals are more susceptible to DNA methylation compared to controls. Our pilot study suggests that the genome-wide aberrant DNA methylation patterns of obese individuals may advance not only our understanding of the epigenomic pathogenesis but also early screening of obesity in youth
