This paper analyzes the characteristics of technological knowledge flow-structure of Korean manufacturing in dynamic perspective. In doing that, the concept of the knowledge network is introduced which is defined as a set of industries and their interaction(knowledge flow) or linkage. The analysis of the inter-industrial knowledge flows is based on the technological similarity by using R&D researchers' academic background in the year of 1984, 1987, 1990. The analysis is carried out by such methodology as network analysis, indicator analysis and simple statistical analysis. And the final results are drawn both in absolute terms(dimension effect) and in relative terms(proportion effect) respectively. The main findings are as follow. First, the Korean manufacturing knowledge network appears to strengthen existing inter-industrial knowledge linkages rather than to construct new linkages. Second, the network seems to form a dualistic structure in that some high-technology sectors(knowledge production sectors) emerge along with traditional sectors(knowledge absorbing sectors). Third, since the mid-1980s, an inter-industrial fusion is witnessed among technologically intensive sectors, indicating that some sophisticated innovation modes are emerging in Korean manufacturing system. And fourth, by using the relations of the inter-industrial knowledge-flows, we classified manufacturing industries into 3 type ; knowledge-outflow sector, knowledge-inflow sector and knowledge intermediary sector.

우리나라와 같이 수출주도형 산업구조를 가진 국가에서는 해외시장과의 밀접한 연계로 인하여 해외시장이 국내 경제활동에 충격을 전달하는 경로가 될 가능성이 높다. 본고에서는 우리나라에서 유가의 변동이 국내시장과 수출시장을 통하여 어떻게 전달되는지를 설명하고자 하였다. 이를 위해 4개의 거시경제변수와 개별 제조업의 산업생산, 국내생산자가격, 수출가격을 포함하여 유가상승에 따른 개별 산업활동의 충격반응함수를 구조적 VAR모형을 이용하여 추정하였다. 이로부터 에너지다소비업종을 제외한 대부분의 제조업에서는 유가상승 후 생산감소와 가격하락이 나타났고, 비금속광물제품(26), 컴퓨터 사무용기기(30), 전자부품 영상 음향 통신장비(32)를 제외하고는 유가상승에 대하여 수출가격이 상승하는 것으로 추정되었다. 이는 국내시장에서 유가상승이 수요충격의 경로로 확산되고 있으나, 수출시장에서는 공급충격의 경로가 존재하고 있어, 대체로 우리나라 제조업은 유가상승에 대하여 이중적 부담을 안고 있는 것으로 설명할 수 있다.

본 연구의 목적은 한국과 중국 제조업의 기술효율성과 생산성, 환경을 포함한 기술효율성과 생산성 그리고 황산화물($SO_x$) 저감의 잠재가격을 측정해 보고자 함이다. 2000~2004년간 환경을 포함한 경우와 불포함한 경우에 중국의 기술효율이 한국 제조업의 기술효율보다 높았다. 대부분 개별 중국 제조업의 기술효율이 한국 제조업의 기술효율보다 높았다. 환경을 제외한 일반적 생산성 변화를 기준으로 한국 제조업의 연간 증가율은 1.13%였으나 중국은 2.73% 수준이다. 그러나 $SO_x$ 저감을 고려한 연간 생산성 변화는 오히려 한국이 2.41%로서 중국의 1.58%보다 높았다. $SO_x$ 잠재가격으로 추정한 한계저감비용은 한국 제조업이 오염 1단위 저감에 평균 1.4731단위 생산액 감소가 필요한 반면 중국 제조업은 매우 적은 평균 0.0049단위 생산액 감소로 추정되었다. 한국 제조업은 기술효율성과 생산성이 높은 업종으로 특화하고 오염처리비용에서 효율을 유지하는 노력이 필요하다.

This study was performed to evaluate the asbestos exposure levels and variations in textile, brake lining manufacturing and slate manufacturing industries. For this study, fifteen plants of brake lining manufacturing industry, 7 plants of textile industry, and 2 plants of slate manufacturing industry were selected and surveyed. Geometric means (GMs) of airborne asbestos concentrations in textile, brake lining manufacturing, and slate manufacturing industries were 1.42 f/cc(0.07-6.1O f/cc), 0.19 f/cc(<0.01-2.67 f/cc) and 0.08 f/cc(0.02-0.67 f/cc), respectively. In textile industry overall GMs of airborne asbestos concentrations in plants with less than 50 workers and in plants with more than 50 workers were 1.60 f/cc and 0.3 f/cc, respectively. Therefore, the size of plant showed some difference in the airborne asbestos concentrations. Three out of 7(42.9%) exceed the Korean standard, 2 f/cc, and every plant exceed the USA standard, 0.2 f/cc of the OSHA-Permissible Exposure Level(OSHA-PEL). Especially, one plant showed the highest average concentration of 2.87 f/cc. In brake lining manufacturing industry, the plants with less than 50 workers showed 0.22 f/cc. The plants with more than 50 workers showed 0.18 f/cc. All plants showed the exposure level below the Korean standard. Five of 15 (33.3%) were above the OSHA-PEL. One plant showed the highest average concentraton of 0.84 f/cc. In slate manufacturing industry, the average exposure level was 0.08 f/cc, and all of the plants were below the Korean standard and the OSHA-PEL.
