This article analyzes the effects of energy price increase induced by GHGs mitigation policy on automobile industry empirically. An increase in energy price due to GHGs mitigation policy does not have a significant effect on the production and the value-added in automobile industry. Electricity price has a negative effect on the production and the value-added in automobile industry, but it is not significant. However, employment is significantly affected by a change in electricity price. Export is also affected negatively, but the effect is insignificant. These results imply that GHGs mitigation policy such as carbon tax might affect adversely the employment in automobile industry. Especially, their effects on employment are significant. Therefore, some moderating measures to relieve the adverse effects on employment in automobile industry should be called upon with the implementation of GHGs mitigation policy.

This paper illuminates the patterns of growth and declines in sizes of union membership in metal, chemical, financial, and auto transport sectors in three distinct periods during the last four decades from 1963 to 2003. This paper also calculates union densities in auto assembly, auto supply, and shipbuilding industries of the metal sector, cement, petroleum refining, and pharmaceutical industries of the chemical sector, private banking industry of the financial sector, and city bus industry of the auto transport sector. Such diversities in both sizes of union membership and union densities among sectors and industries turned out to be associated with attitudes and choices of employers and unions in interaction with sector- and industry-specific economic (growth stage and path), institutional (degrees of government intervention), and social (demographic features of employees and prevailing sizes of firms) environment. Such finding shows that theoretical reasonings on sizes of union membership and union densities across sectors and industries in advanced nations are also relevantly useful to analyze the Korean case.

The purpose of the study is to present an analysis of the expatriate leasing market for highly-paid professionals residing in Seoul. The effects of physical and locational attributes, range of amenities along with expat's national and industrial attributes on housing rents are being empirically evaluated based on transactions. Using lease transaction data for the period of 1994 through 2013, the results show that physical and locational attributes which have been proved to affect conventional housing value are also confirmed to affect leasing housing rent for expatriate. Also this study finds the following results. First, housing rent is found to be influenced by foreign residents' occupation. Therefore banking, petrochemical, insurer and pharmaceutical company affect positively on housing rent while mechanic firms influenced negatively to rent. Second, housing rent is found to be affected by foreign residents' nationalities. The results indicate USA and the United Kingdom have a positive effect while French has a negative effect on rent.

The purpose of this study is to recognize the importance of sustaining the coal industry in spite of the declaration of new climate change regime. Due to the importance to have the ability to control the supply and demand for energy source, this study will present the ground supporting the need to save some fixed amount of coal to carry out this task. The relative quantity of fossil fuel like coal and oil consumed as an energy source is reduced due to the increasing portion of renewable energy sources. Nevertheless, we can verify the fact that the position as a main energy source in demand for and supply of electric power is still valid. And the optimal amount of coal storage is estimated through the average annual amount of demand derived from preceding studies. In this context, it is very urgent problem to maintain the coal industry as a industrial policy for the sustainable national economic growth through the coal storage policy and to determine the optimal amount of annual storage.

방식 코팅 기술은 조선해양산업은 물론 에너지, 철강 및 비철 소재, 건설 산업 등 산업 전반에서 폭넓게 적용되고 있다. 또한 산업 고도화에 따라 점차 가혹해지는 소재의 적용 환경을 고려해보면 향후 지속적으로 산업 수요가 증대될 것으로 예상할 수 있는 기술이다. 특히 아크 열용사법을 이용한 방식 코팅 기술은 미국이나 일본과 같은 선진국에서는 해양플랜트, 석유 시추시설 등 대형 해양 구조물은 물론 다리, 항만시설과 같은 철재 또는 시멘트 구조물의 방식 기술로 널리 적용되어 일반화된 기술이다. 그러나 국내에서는 아직까지도 초기 비용 상승 및 미약한 관련 기술 등의 이유로 대부분 방식도료를 사용하고 있는 실정이다. 그리하여 단기 수명에 따른 재시공 시 많은 환경오염을 유발하는 방식도료를 대체할 수 있는 아크 열용사법을 이용한 방식코팅 기술에 대한 관심과 수요가 점차 증가되고 있다. 그 일환으로 본 연구에서는 해양 구조물 강재의 방식을 위해 니켈계 용사재료를 이용하여 아크 열용사 코팅을 실시한 후 다양한 전기화학적 실험을 통해 내식성을 평가하고자 하였다. 아크 열용사 코팅은 구조용 강재 SS400강에 대하여 니켈합금 선재(1.6 Ø)를 사용하여 실시하였다. 용사 시 용사거리는 200 mm, 공기압력은 약 $7kg/cm^2$ 정도로 유지하면서 용사코팅을 실시하여 약 $200-250{\mu}m$ 두께로 코팅 층을 형성시켰다. 그리고 전기화학적 실험은 천연해수 속에서 자체 제작한 홀더(holder)를 이용하여 $3.14cm^2$의 용사코팅 층만을 노출시켜 실시하였다. 그리고 기준전극은 은/염화은 전극을, 대극은 백금전극을 사용하였다. 전기화학적 실험을 통해 부동태 특성 및 용사코팅 층 표면의 양극 용해반응 특성을 분석하기 위한 양극분극 실험은 OCP로부터 +3.0 V까지 실시하였다. 또한 부식전위 및 부식전류밀도 분석을 위한 타펠분석은 OCP를 기준으로 -0.25에서 +0.25 V까지 분극시켜 실시하였다. 그리고 주사전자현미경과 3D 분석을 통해 부식손상 표면을 관찰하였다. 그 결과 니켈합금으로 용사코팅된 강재의 내식성이 상당히 향상되었다.

This paper is concerned with the effect of an increase in the import price of LNG on the Korean economy and industries. A computable general equilibrium analysis is applied to compute the comparative-statical effect of 10% rise of LNG price. The price increase places relatively heavy burden on the city gas, oil products and thermal power, decreasing their outputs and domestic sales by relatively larger percentages than other industries. The 10% increase in the LNG price reduces GDP by 0.4% and raises the general price level by 0.08%. The increase in oil price resulting in the same decreasing rate of GDP caused by the 10% LNG price rise turns out to raise the general price level and reduce the consumer's welfare in terms of equivalent variation by less percentage than the increase in LNG price.

Ousters have become a key focus of interest and analysis over the last decade or so, informed by the work of the Harvard business economist Michael Porter. Recent research, however, suggests that the classic Porterian conception of clusters needs to be rethought. In particular, the idea that clusters are geogaphically bounded and integrated units whose primary link to the outside world is through the export of goods and services to global markets is highly Questionable, if not untenable. Relational approaches to clusters and regional development stress the importance of the wider networks and 'pipelines' through which knowledge is exchanged with key partners and collaborators located outside of the particular cluster in question. Rather than the main external links being those between leading firms and global markets, firms may engage in a range of global relations with collaborators and suppliers. This paper address the challenge of rethinking clusters in the light of the recent emphasis on global networks md connections, drawing on experience from m old industrial region in Western Europe Scotland. In assessing cluster experiences and initiatives in Scotland, I examine the development of the oil and gas and electronics clusters. In conclusion, I suggest that cluster initiatives me only likely to generate lasting benefits for the region in question if there is significant local ownership md control of key industries and clusters.
