  • The Japanese government has carried out the power industry reform in three phases to supply power stably, control the rise of electricity tariff, and expand consumer choices. The reform of the Japanese electric power industry fosters new kinds of businesses as well as changes the competitive structure in which the enterprises participating electricity business compete. However, for the power industry restructuring to be done smoothly, the accompanying tasks should be carried out. Korea has also been devoting a lot of efforts to cultivate various types of new industries based on the convergence of energy and information and communications technology. If there are the same kinds of new industries between the two countries, the progresses of the industries can be compared to each other over a period of time.

  • Most of the laws and standards relevant to technology in Korea bear a resemblance to those in Japan. Electricity was not introduced to Korea until Lighting ceremony in Kyong-Bok palace observed in 1887. Since Korea was annexed to Japan in 1910 and our public works were under Japan control we have applied Japanese laws and regulations made by Chosun government-general. Independently from Japan the power electricity accepted power plants of USA, codes of NESC, ASME / ANSI, NEMA. Our generation and distribution system takes American style while our consumer side takes Japanese style. As global trade system was transferred GATT into WTO, the harmonization of technological standards, certification construction testing in the trend of world. This paper is based on WTO / TBT agreement coming in effect after 12th, April, 1979. For Korea the distribution system has a strong resemblance to American system so that unconvertible because IEC 60364 originated from Europe while NEC originated from USA. This papers deals with the fundamental elements of electrical safety system with comparing IEC 60364 with NEC. This paper considers how engineers should apply NFPA 70(NEC) and IEC based on the comparison of NEC to IEC in relation to electrical installations.

  • The iron and steel industry is a manufacturing industry with the largest greenhouse gases emissions and has a great ripple effect on the national economy as a core material industry. This study internationally compared the decoupling patterns of greenhouse gases emissions in the iron and steel industry from 1990 to 2019, focusing on Korea, Japan, and Germany. In particular, unlike previous studies that considered only fuel combustion emissions, this study considered all fuel combustion emissions, industrial process emissions, and indirect emissions from the use of electricity and heat. As a result of the analysis, Korea is interpreted as expansive coupling, Japan as decoupling, and Germany as unclear. Therefore, the decoupling path that the Korean iron and steel industry should take should not be in Germany, but in the form of seeking a decoupling method similar to Japan or more effective than Japan. In addition, this study considered the characteristics of the iron and steel industry as much as possible and presented the causes of the decoupling analysis results and implications for the Korean iron and steel industry through comparison with Japan and Germany. In particular, four factors were suggested as factors which has promoted decoupling in Japan: high value-added of Japanese iron and steel products, development of energy efficiency technology in the Japanese iron and steel industry, strategic M&A of the Japanese iron and steel industry, and maintaining competitiveness according to the closed distribution structure of Japanese iron and steel products. The Korean iron and steel industry should also use the case of Japan as a benchmark to further increase added value through quality uprade and product diversification of iron and steel products, while at the same time making efforts to fundamentally reduce greenhouse gas emissions through the development of new technologies.

  • This study investigates the impact of exchange rate and exchange rate volatility on the stock prices of eight industries from 2006 to 2015. The first and second exchange rate exposure of these eight industries is estimated with respect to four different exchange rates, namely the US dollar, Japanese yen, European currency unit, and British pound. In exchange rate exposure, stock prices in foods-beverages, paper-wood, electricity-gas, and banks industries are negatively related to exchange rate, whereas stock prices in electrical-electronic equp. and transport-equp. industries are positively related to exchange rate as expected. However stock price in machinery industry is negatively related to exchange rate, which is opposite to the expectation. Negative relationship is found between stock price in chemicals industry and exchange rate. In exchange rate volatility exposure, stock price in paper-wood industry is found to be negatively related to exchange rate volatility. Stock price in banks industry is also negatively related to exchange rate volatility. This result is opposite as expected, because banks are supposed to get more revenue by issuing derivatives related to foreign exchange when exchange rate volatility increases.

  • Most Technological laws of Korea are almost identical to those of Japan. Electricity was not introduced to Korea until lighting ceremony in Kyong-Bok palace observed in 1887. Since Korea was annexed to Japan in 1910, Korea have applied Japanese law and regulations made by Chosun government-general. And public works were under Japan control. Korea accepted adopted the power plants of America, codes of NESC, ASME / ANSI, MEMA while Japan accepted or adopted only IEC. Our generation distribution system takes American style while our consumer side takes Japanese style. As global trade system was transferred GATT into WTO, the technological standards, certification, construction and testing are in harmony internationally. The WTO / TBT agreement came in effect after 12th, April, 1979. The sections in the agreement require the members to exchange their own standards and codes for the harmonized ones by degree. The Korean distribution system has a strong resemblance to American system so that the internal engineers are confused in application of the relevant standards. IEC60364 and NEC are technologically similar but practically unconvertible because both have their different originality, that is to say Europe and USA. This paper deals with the fundamental elements of electrical safety system on review of IEC 60364 and NEC. This paper considers how engineers should apply IEC60364 and NFPA 70(NEC) based on all-the-way review of them.
