Growth of the Korean economy has been sluggish, and this situation is more pronounced in the service sector. We argue that capital misallocation, especially in the service sector, could contribute to this slowdown. Utilizing firm and sectoral level data, first we assess the rising dispersion of the marginal revenue product of capital (MRPK) driven by the service sector. This could represent a widening misallocation of capital. Furthermore, a panel regression shows that within-sector misallocations at the sectoral level are closely correlated with the lower growth rate of sectoral real value added. Again, this is mainly observed in the service sector, but not in the manufacturing sector. Misallocations of other resources, labor and the intermediate inputs do not stand out.

Micro, small, and medium-sized enterprises (MSMEs) have been acknowledged to play a key role in promoting innovation and economic development. In Peru, 99.5% of formal firms are MSMEs, thus promoting innovation in these firms could have a significant impact on the Peruvian economy. In spite of Innovate Peru's efforts, Peru is still one of the countries that invests the least in innovation, with MSMEs offering low value added. Innovate Peru has launched programs (technological missions) to improve MSMEs' innovation through technology-transfer-oriented subsidies, which may strengthen companies' absorptive capacity (AC) and thus their capabilities to identify and integrate internal and external knowledge. This study assesses the impact of these programs on MSMEs. Data were collected from 85 MSMEs that participated in Innovate Peru's technological missions between 2014 and 2016. Findings show that all the dimensions of AC have a positive impact on innovation; however, the impact of economic subsidy was found to be non-significant. Theoretical and practical implications are discussed.

기후산업은 세계기후변화협약에 대응할 수 있는 산업으로서 기후변화를 창출하거나 이에 대응하는 모든 산업군으로 정의될 수 있다. 본 논문은 그중 신재생에너지산업에 한정하여, 2011년 한국은행에서 발표한 2009년 산업연관표를 활용하여 경제적 파급효과를 분석하였다. 분석의 결과, 2009년 현재 한국 신재생에너지산업은 1원의 생산량 증가를 통해 1.1644원의 생산을 유발하였으며, 0.3544원의 부가가치를 유발한 것으로 분석된다. 취업유발효과는 10억원의 생산량 증가를 통해 10.065명의 취업을 유발한 것으로 분석된다. 그리고 산업구조 전체 속에서 신재생에너지산업의 상대적 위치를 설정하는 산업연쇄효과는 아직 크지 않은 것으로 나타났다. 향후 신성장동력으로 지정한 신재생에너지산업을 활성화하기 위해서는 부가가치를 제고하기 위한 정책이 더욱 활발하게 추진되고, 신재생에너지산업의 부가가치사슬망(value-chain)에 관련된 산업들에 대한 정책도 함께 마련되어야 할 것으로 판단된다.

In the last couple of decades industrialization and technological development has not only increase in the scale of electrical facilities and it has become more and more complicated and diversified. Furthermore, fires in the electrical transformers, like those that have knocked out power in the country in the past years, are likely to become more common as utility systems begin to show their age. The importance of preventing electrical accidents can never be overemphasized and for this reason, supply of on-line diagnosis system combining information and communication technology(ICT) for the customer's electrical facilities has been increasing recently. The major advantage of on-line diagnosis system is that the device's potential problems could be detected early before a serious deterioration or breakdown occurs. In this paper, We estimated the benefit from the investment in the right of present value of sales, success rate of commercialization regarding R&D investment for development and commercialization of on-line diagnosis technology targeting customer electrical facilities. As a result, the net value added of 29.7 billion won and the increased profit by roughly 7.52 precent are expected.

${\delta}^{13}C$ and ${\delta}^{18}O$ values were determined for the Paleozoic limestones (Great Linestone Series) from the Taebaegsan region and the age-unknown limestones (Janggun Formation) from the Janggun mine, Korea. Limestones of the Great Limestone Series exhibit a range of carbon isotopic composition from -4.5 +1.3‰ with a mean ${\delta}^{13}C$ value of -1.1‰, relative to the PDB standard, and of oxygen isotpic composition from +8.8 to +23.3‰ with a mean ${\delta}^{18}O$ value of +16.0‰, relative to the SMOW, falling into the normal marine limestone range according to Keith and Weber (1964), and Degens and Epstein(1964). Carbon isotopic composition of limestones of the Great Limestone Series becomes progressively lighter from Pungchon limestone of middle Cambrian age to mid-Ordovician Maggol limestone, possibly due to change in depositional environment in the Taebaegsan basin. Variation in isotopic composition of limestones from Hwajeol to Dumugal formation offers the possibility or deposition in shallow sea environment, in which fresh waters were added in several stages. Janggun limestone of unknown age may be corelated with the Paleozoic limestones of Great Limestone Series as infered from the istopic composition ranging from -2.8 to + 0.7‰ of ${\delta}^{13}C$ and +13.4 to +22.4‰ of ${\delta}^{18}O$.

This study investigates the recycling potential of demolition waste (DW) according to building structure, while considering economic aspects. For that, this study surveyed 1,034 residential buildings to collect reliable information on demolition waste generation rates (DWGRs). This study suggested a method for operational cost calculation for each stage and carried out an inventory analysis. The economic value of recycled DW materials was also calculated. And then, the recycling potential(RP) was calculated by building structures and waste types. RP by building structure was low (27-40%), and RP was found in the order of masonry-block, wooden, RC and concrete-brick. By type of DWs, the RP of aggregates was considerably lower than 7%, and DWs such as wood, plastics, and metals showed more than 100% RP. Considering the results of this study, In order to improve the RP of buildings and DWs, the diversification of products that recycled waste like aggregates (i.e., mortar, concrete, bricks, blocks, tiles) and the development of high value-added products are considered to be the most urgent problems. Based on the above RP results, this study proposed a more advanced method for life cycle assessment of buildings and demolition waste.
