"South Korea has attained spectacular economic success in recent decades. It has reached the status of a Newly Advanced Economy, with challenges increasingly mirroring those faced by other advanced economies. These include the necessary upgrading of the labor force, the frictions of switching to a national system of innovation adapted to leadership in R&D, market-based economic policies that reflect the government’s difficulties in foreseeing future technological developments, and the consequences of social change for the innovation system and policy-making. In the forthcoming book the parallel challenges for innovation and technology for the Republic of Korea and other advanced economies will be analyzed more thoroughly with an international perspective in mind. This comparison and international benchmarking will allow policy makers and scholars to better appreciate how much the country has already moved into the circle of globally leading economies and what can be done to consolidate and strengthen its position."

"ABSTRAK The fractionation of five heavy metals in a washing aggregate sludge, a sewage sludge, a clay-rich sediment, the mixtures of these materials and the lightweight aggregates manufactured with them has been determined by applying the optimezed European Community Bureau of Reference sequential extraction procedure in order to evaluate the effects of the heating process on the extraction of these elements. Additionally, preparation of efaluates by aggregate leaching has been performed in accordance with the UNE-EN-1744-3 standard. The availability of all the studied heavy metals has been reduced by the thermal treatment, since most of the heavy metals have become part of the undigested material in the lightweight aggregates. Nickel has been the heavy metal that has presented the highest concentration in the eluates obtained after completion of the single extraction procedure in the lightweight aggregates. The studied lightweight aggregates may be used in lightweight concerte manufacturing from the standpoint of heavy metal leaching. "
