The relationship between export growth and economic growth in developing countries has been one of the main issues in the growth theory field. Many of empirical studies have been done during the last three decades in order to investigate the export-led growth hypothesis using either time-series or cross-sectional data mainly in developing countries. This paper applies cointegration and error correction models to test causal relationship between export growth and economic growth in the Korean 8 manufacturing industries using the industrial time-series quarterly data over 1975-2010. The export-output relationship is tested by including industrial capital stock and the industrial labor force as exogenous variables. The cointegration and error-correction modelling technique with industrial export and output data have showed the strong evidence that there is a bi-directional causality between industrial export and industrial output in 6 manufacturing industries except wood & pulp and nonmetallic industries.

Occupational injury rate of Korea recently slides slightly downward after stagnating around 0.7%'s for more than 10 years. To accelerate this trend, injury prevention for small enterprises is crucially important because vast majority of injuries take place in small enterprises. Considering huge number of small enterprises, we need to focus our efforts to type of riskier industries. By analysing detailed injury data, we select type of industries which need our concentrated prevention efforts. Several preventive measures are recommended, after we made literature survey of case studies for small enterprises. The result identifies riskier type of industries including transportation machinery manufacturing industry type(B), woods & veneer manufacturing industry, etc. Safety of machinery, new enterprises less than 2 years in service and new employees serving less than 6 months are in need for focused prevention efforts. To cope with these vulnerable spots, recommended preventive measures include strengthening of machinery safety standards, early assistance for safety to new enterprises, mandatory safety education before employment, etc.

Background: Recent research on occupational injuries in companies has faced difficulties in obtaining representative data, leading to studies relying on surveys or case studies. Moreover, it is difficult to find studies on how a company's industry characteristics affect occupational injuries. This study aims to address these limitations. Methods: We collected 11 years of disclosure data from 1,247 listed companies in the Korean stock market and combined it with their occupational injury histories collected by the Republic of Korea Occupational Safety and Health Agency (KOSHA) to build a dataset. We attempted to analyze a linear panel model by dividing the dataset into manufacturing, construction, and other industries. Results: The higher proportion of full-time employees and better job skills correlate with lower occupational injuries in other industries. The wage increase reduces occupational injuries in manufacturing and other industries, but the substitution effect produces the opposite outcome in construction. Also, foreign ownership and credit ratings increase effectively reduce occupational injuries mainly in the manufacturing industry. Conclusion: Our results suggest that in explaining the relationship between corporate characteristics and occupational injuries, it is necessary to consider the nature of the industry more closely, and in particular, employment and labor policies for preventing occupational injuries need to be selectively applied according to industry. In addition, to improve the limitations and increase the usability of the research results, further detailed studies are needed in the future.

We investigate the effect of ICT capital on the demands for labor and energy in manufacturing and electricity gas water industries of Korea, US, and UK. Assuming ICT capital, non-ICT capital, labor, electricity, fuel, and material as input factors for manufacturing and ICT capital, non-ICT capital, labor and energy material as input factors for electricity gas water industry, we estimate the Morishima elasticities of substitution. Considering the relative price changes of input factors, ICT capital has substituted labor in manufacturing and electricity water gas industries of the three countries. ICT capital has substituted both electricity and fuel in US and UK manufacturing. Although ICT capital has substituted electricity and fuel each other in Korean manufacturing, ICT capital is unlikely to decrease the demands for electricity and fuel when considering their relative price changes. ICT capital has substituted energy material in electricity gas water industries of the three countries.

This study aim to use the GTAP model to analyze the impact of RCEP Fermentation in the Korean manufacturing industry by quantifying the RCEP tariff commitment table. The research results show RCEP has boosted output in all sub-manufactures except wood and printed matter due to increased export volumes. Wood products, on the other hand, are more reliant on imports due to lower production due to lower domestic sales or overall exports. After RCEP came into effect, the import and export scale of Korea's manufacturing industry expanded effectively. Among them, the positive impact on the intensive low-tech manufacturing industries such as clothing and leather products, wood products and printing products, and food, beverage and tobacco products is greater than the positive impact on the technology-intensive medium and high-tech and high-tech manufacturing industries. And found that the growth rate of Korea's manufacturing trade is basically proportional to the tax reduction rate of RCEP. Finally, in order to promote the development of the manufacturing industry, some suggestions are put forward that need the government's policy support and strengthen the regional cooperation with RCEP member countries.

This study attempted an AHP analysis through interview with experts in the industries and questionnaire survey on recognition of organization members and future strategic development direction in order to upgrade shipbuilding equipment industries to marine plant equipment industries. Key research results are as follows. First, according to analysis on relative priority between three aspects on acceleration of shipbuilding equipment industries, importance was shown in the order of acceleration of internal competence, acceleration of manufacturing technology, and acceleration of supply chain, which means that the aspect on acceleration of internal competence had relatively higher importance. Second, as for relative importance of detailed item evaluation per respective aspect, it was found that development of core competencies was high from the aspect on acceleration of internal competence, higher value-addition was high from the aspect on acceleration of manufacturing technology, and IT infrastructure construction was high from the aspect on acceleration of supply chain.

Entrepreneurship is considered as the main leadership creating enterprises and employment. However, in Korea empirical studies linking Korean entrepreneurial performances with her characteristics are rarely in existence. Current study focuses on Korean entrepreneurs in manufacturing, construction and other technologically intensive (MCOT henceforth) industries compared to entrepreneurs in service and other technologically less intensive (SOT henceforth) industries and to professional/technical wage workers and examines effects of human capital, demographic, and risk-taking characteristics on earnings. Education premium is higher for entrepreneurs in MCOT industries than for professional/technical workers, even though science and engineering diploma pays better in the latter, and that concentration in college causes more selection into the latter occupational family. In terms of education premium and effects of other characteristics SOT industry entrepreneurship and self-employment appear to be lower grade occupational families, even though there appear to be significant comparative advantages working in their selection.

Most pipe-inspection robots have fixed sizes and use a wired cable system. Pipelines are generally composed of various structures, including bent pipes, vertical pipes, branch pipes, and holes, and it is difficult to explore the insides of such modular piping structures. In an offshore plant pipeline, a robot that can pass through the pipe hole in the downward direction or avoid obstacles, such as a measuring instruments, has not been introduced yet. In this study, an inspection robot that can travel through most pipelines in offshore plants is proposed. This robot uses mecanum wheels; upward, downward, and rotary motion; and a novel rotatable mechanism. Moreover, the robot is designed to be compact and lightweight to include additional devices in the middle.
