Factores asociados a la enfermedad discal lumbar de origien laboral calificados por la junta de calificación de invalidez regional de Meta, entre 2001 y 2014

La enfermedad de disco lumbar de origen laboral se presenta como una patología frecuente a nivel mundial en la masa trabajadora de diferentes sectores económicos expuesta a factores de riesgo biomecánico, afectando negativamente a la persona como ser individual y social, y repercutiendo en las economías en diferentes niveles. Objetivo Establecer la prevalencia de los factores de riesgo biomecánico en los casos con diagnóstico de enfermedad de disco lumbar calificados como enfermedad de origen laboral por la Junta Regional de Calificación de Invalidez del Meta, en el período comprendido entre 2011 a 2014, explorando la asociación entre los factores sociodemográficos y laborales. Metodología: Estudio de corte transversal con información retrospectiva de historias clínicas de pacientes con enfermedad de disco lumbar calificados de origen laboral, entre el 2011 – 2014. Resultados: La prevalencia de los factores de riesgo biomecánico fue: flexión columna con 94.1%, caminando durante la mayor parte de la jornada laboral 51.7%, levantar y/o depositar manualmente objetos 53.4%, manipulación de carga mayor a 25 kg, 49.2% y vibración cuerpo entero más de 4 horas 16.9%. Estos factores fueron mayores en trabajadores de obras civiles y manipuladores de materiales con 20.3%, en actividades económicas de servicios con 33.1% y construcción 21.2%. Se encontró asociación estadísticamente significativa de la enfermedad de disco lumbar con el género y la exposición a vibración/impacto cuerpo entero. Conclusión: Los factores de riesgo biomecánico como la posición de la columna vertebral en flexión, el levantamiento y depósito de carga, la manipulación de peso mayor a 15 kgs, la postura de cuerpo caminando, la exposición a vibración a cuerpo entero, y el tiempo de exposición, son elementos fundamentales a tener en cuenta en el proceso de calificación de origen de la enfermedad discal lumbar.

The Asian summer monsoon: an intercomparison of CMIP5 vs. CMIP3 simulations of the late 20th century

The boreal summer Asian monsoon has been evaluated in 25 Coupled Model Intercomparison Project-5 (CMIP5) and 22 CMIP3 GCM simulations of the late 20th Century. Diagnostics and skill metrics have been calculated to assess the time-mean, climatological annual cycle, interannual variability, and intraseasonal variability. Progress has been made in modeling these aspects of the monsoon, though there is no single model that best represents all of these aspects of the monsoon. The CMIP5 multi-model mean (MMM) is more skillful than the CMIP3 MMM for all diagnostics in terms of the skill of simulating pattern correlations with respect to observations. Additionally, for rainfall/convection the MMM outperforms the individual models for the time mean, the interannual variability of the East Asian monsoon, and intraseasonal variability. The pattern correlation of the time (pentad) of monsoon peak and withdrawal is better simulated than that of monsoon onset. The onset of the monsoon over India is typically too late in the models. The extension of the monsoon over eastern China, Korea, and Japan is underestimated, while it is overestimated over the subtropical western/central Pacific Ocean. The anti-correlation between anomalies of all-India rainfall and Niño-3.4 sea surface temperature is overly strong in CMIP3 and typically too weak in CMIP5. For both the ENSO-monsoon teleconnection and the East Asian zonal wind-rainfall teleconnection, the MMM interannual rainfall anomalies are weak compared to observations. Though simulation of intraseasonal variability remains problematic, several models show improved skill at representing the northward propagation of convection and the development of the tilted band of convection that extends from India to the equatorial west Pacific. The MMM also well represents the space-time evolution of intraseasonal outgoing longwave radiation anomalies. Caution is necessary when using GPCP and CMAP rainfall to validate (1) the time-mean rainfall, as there are systematic differences over ocean and land between these two data sets, and (2) the timing of monsoon withdrawal over India, where the smooth southward progression seen in India Meteorological Department data is better realized in CMAP data compared to GPCP data.

Palaeovegetation (Communications arising): diversity of temperate plants in east Asia

The exceptionally broad species diversity of vascular plant genera in east Asian temperate forests, compared with their sister taxa in North America, has been attributed to the greater climatic diversity of east Asia, combined with opportunities for allopatric speciation afforded by repeated fragmentation and coalescence of populations through Late Cenozoic ice-age cycles1. According to Qian and Ricklefs1, these opportunities occurred in east Asia because temperate forests extended across the continental shelf to link populations in China, Korea and Japan during glacial periods, whereas higher sea levels during interglacial periods isolated these regions and warmer temperatures restricted temperate taxa to disjunct refuges. However, palaeovegetation data from east Asia2, 3, 4, 5, 6 show that temperate forests were considerably less extensive than today during the Last Glacial Maximum, calling into question the coalescence of tree populations required by the hypothesis of Qian and Ricklefs1.

Ubiquitous and smart system approaches to infrastructure planning : learnings from Korea, Japan and Hong Kong

The robust economic growth across South East Asia and the significant advances in nano-technologies in the past two decades have resulted in the creation of intelligent urban infrastructures. Cities like Seoul, Tokyo and Hong Kong have been competing against each other to develop the first ‘ubiquitous city’, a strategic global node of science and technology that provides all municipal services for residents and visitors via ubiquitous infrastructures. This chapter scrutinises the development of ubiquitous and smart infrastructure in Korea, Japan and Hong Kong. These cases provide invaluable learnings for policy-makers and urban and infrastructure planners when considering adopting these systems approaches in their cities.

Economic relations between Latin America and the Caribbean and the Republic of Korea: Advances and opportunities

This document was prepared by the Economic Commission for Latin America and the Caribbean (ECLAC) for the official visit of Geung-hye Park, President of the Republic of Korea, to several countries in the region. The Republic of Korea’s success in economic and social development offers many lessons for Latin America and the Caribbean and the developing world as a whole. From being one of the poorest countries in the world in the early 1960s, in six short decades the Republic of Korea has succeeded in transforming itself into a high-income economy, a major manufacturing, scientific and export power and a highly cohesive society with impressive levels of educational achievement.

The Study of International Cultural Relations of Postwar Japan

The paper examines policies and activities of cultural exchange carried out by Japanese national, local and private agents since the end of WWII. Methodologically, we distinctively use the notion culture as a tool and as an object of study, and to synthesize the two in full intention, based on the debate among IR students about so called Cultural Turn in IR theories. As case studies, the Japanese experiences are examined from two points. Firstly, it is compared with the German experiences in Europe, with special attention to the construction of national identity.In both countries, the peoples tried to make use of cultural exchange activities in the management of international relations. The actual developments of cultural relations by the two countries, however, were in striking contrast to each other. Secondly, our study focuses on the explosive expansion of private sector's international cultural exchange in the 1980s in association with so called "emerging civil society" phenomenon observed worldwide throughout 1970s and 1980s. By using our original approach mentioned in the Chapter 1, the paper tries to sketch out that the increase of the private organizations is largely the response of the Japanese society to outside influences, not something genuinely outgrown from within the society itself due to mainly domestic causes.

Foreign Direct Investment Relations between Myanmar and ASEAN

Myanmar highly appreciates foreign direct investment (FDI) as a key solution reducing the development gap with leading ASEAN countries. Accordingly, it is welcomed by the government. Myanmar's Foreign Investment Law was enacted in 1988 soon after the adoption of a market-oriented economic system to boost the flow of FDI into the country. Foreign investors positively responded to these measures in the early years and FDI inflow into Myanmar gradually increased during the period from 1989 to 1996. However, after 1997, FDI inflow was dramatically reduced and markedly declined until 2004. In 2005, FDI inflow increased at an unprecedented rate and reached the highest level in the country's history. However, this growth was not sustainable in the subsequent years, as it declined again and turned stagnant at the previous level. In terms of source regions, ASEAN is a major investor in Myanmar, which investment is significantly exceeds the combined investment of other regions of the world. Among top ten countries, Thailand's investment alone is significantly more than combined total investments of the other nine countries. Next to Thailand in terms of investments in Myanmar are Singapore and Malaysia among ASEAN, at second and third places, respectively. The combined total FDI inflows into the power and oil and gas sector represent about 65 percent of the total investment. There are many opportunities for foreign investment in other sectors, which are not, yet exploited. ASEAN countries will certainly be source countries of Myanmar FDI in the future, and Myanmar should expand to other Asian countries like Japan, India, China, Korea, and Hong Kong where its FDI portfolio is concerned. To effectively attract FDI into the country, Myanmar needs to minimize the effect of policy while opening and encouraging other potential sectors of FDI to foreign investors in ASEAN and Asian countries.

Intra-regional trade between China, Japan, and Korea : before and after the financial crisis

East Asian economies have been heavily dependent on the U.S. and EU markets, especially for the export of final goods. Therefore, once the financial crisis hit Western economies hard, the East Asian economies lost their major markets.Their production networks then worked to the region's disadvantage and stifled industrial development.This reflects the vulnerability of the East Asian economies which have adopted an export-led growth strategy. Such vulnerability needs to be addressed to prevent future economic crises, as well as to sustain economic growth. This paper examines the trade structure of the three countries-China, Japan, and Korea-before and after the Lehman Shock, and discusses how the three countries should cooperate in addressing imbalances in the trade structure.
