  • Due to the Paris Agreement, city gas is drawing attention as an alternative energy source to reduce greenhouse gases. This study conducts a comparative analysis on the economic effects of city gas between Korea and Japan, using input-output(I-O) tables from the Bank of Korea and from Japan's Ministry of Economy, Trade and Industry. The results show that production-inducing, value-added-inducing and employment-inducing effects of Korea's city gas were greater than those in Japan. But supply-shortage and price-pervasive effects of Korea's city gas were also greater than those in Japan. According to these results, production-inducing, value-added-inducing and employment-inducing effects should be sustained, and the policies vitalizing stabilizing supply-shortage and price-change effects, on the other hand, are recommended.

  • Consulting industry is a knowledge intensive business service industry to lead to knowledge creation as well as support high value creation of other industries. While the consulting industry has a great ripple effect on whole industries, there is a lack of interest in the consulting industry. Thus, this study investigates a ripple effect of the consulting service on the national economy using an Input-Output analysis. We summarize some of our findings as follows. First, A production of 1.0 won in the business consulting industry induces production of 0.6933 won in 2005 and 0.7851 in 2009; value-added of 0.2881 won in 2005 and 0.3039 won in 2009. A production of 1.0 billion won in the business consulting industry Industry produces employment for 0.1124 persons in 2005 and 0.1207 persons in 2009. Second, the supply shortage of 1.0 won in the business consulting industry prevents other industries from producing 2.6759 won in 2005 and 3.0145 won in 2009. Third, a 10% increase in the price level of the business consulting industry raises the overall price level from 0.1691% in 2005 to 0.2161% in 2009. The research results show that consulting industry has been increasing a effect on Korea national economy.

  • The Korean government made the 2nd Energy Basic Plan to achieve 11% of new and renewable energies distribution rate until 2035 as a response to cope with international discussion about greenhouse gas emission reduction. Renewable energies include solar thermal, photovoltaic, bioenergy, wind power, small hydropower, geothermal energy, ocean energy, and waste energy. New energies contain fuel cells, coal gasification and liquefaction, and hydrogen. As public and private investment to enhance the distribution of new and renewable energies, it is necessary to clarify the economic effects of the new and renewable energies sector. To the end, this study attempts to apply an input-output analysis and analyze the economic effects of new and renewable energies sector using 2012 input-output table. Three topics are dealt with. First, production-inducing effect, value-added creation effect, and employment-inducing effect are quantified based on demand-driven model. Second, supply shortage effects are analyzed employing supply-driven model. Lastly, price pervasive effects are investigated applying Leontief price model. The results of this analysis are as follows. First, one won of production or investment in new and renewable energies sector induces 2.1776 won of production and 0.7080 won of value-added. Moreover, the employment-inducing effect of one billion won of production or investment in new and renewable energies sector is estimated to be 9.0337 persons. Second, production shortage cost from one won of supply failure in new and renewable energies sector is calculated to be 1.6314 won, which is not small. Third, the impact of the 10% increase in new and renewable energies rate on the general price level is computed to be 0.0123%, which is small. This information can be utilized in forecasting the economic effects of new and renewable energies sector.

  • This experiment was conducted to study the effects of the natural deep sea water, which contained approximately 2.3% salt, and various minerals of K, Mg, Ca, Na, Fe, Mn, Zn, Cu etc, on the immune response and antioxidant activity in rats. 24 Sprague Dawley rats were randomly allotted to a control group and 3 treatment groups. Control rats were supplied with filtered tap water, and each treatment group rats were supplied with 0.5% deep sea water, 1% deep sea water and Jijangsoo, respectively, which is upper clear water separated from sediment by the clay. Feed and water were provided ad libitum throughout the experiment that lasted for 4 weeks. The results showed that 1% deep sea water group showed the highest values in weight gain, feed intake, and feed efficiency than those of other groups. The levels of water intake of 1%- and 0.5%-deep sea water, and Jijangsoo group were 49.1%, 22.8%, and 40.5% higher than that of control group, respectively. The Jijangsoo group rats showed that perirenal and epididymal adipose tissue weights were decreased by 32% and 25%(p<0.05), respectively, when compared to control group rats. There were no remarkable differences of serum glucose concentration among all experimental groups. However, insulin concentration of experimental groups were remarkably increased in order of Jijangsoo (4.54), 1% deep sea water (3.70), 0.5% deep sea water (3.25)(p<0.05). B cell and T cell stimulation were increased about 44.7% and 207%, respectively, by 0.5% deep sea water in comparison with control (p<0.05). TBARS values of 0.5 % deep sea water group were significantly lower than that of control(p<0.05). Catalase and SOD activities of 0.5 % deep sea water group were 200% and 47% higher than that of control, respectively. From the results, it can be concluded that the supply of natural deep sea water can slightly improve the physiological activity which modulates immune response and antioxidant activity in rats.

  • This paper attempts to conduct a comparative analysis on the economic effects of integrated-energy and manufactured gas supply sectors. To this end, an input-output (I-O) analysis is applied using most recently published 2011 I-O table. In particular, the two sectors are specified as exogeneous to identify the economic effects on own and other sectors. Production-inducing effect, value-added creation effect, and employment-inducing effect are quantified based on demand-driven model. Supply shortage effect and price pervasive effect are analyzed employing supply-driven model and Leontief price model, respectively. The results show that production-inducing effect, value-added creation effect, and employment-inducing effect of integrated-energy and manufactured gas supply sectors are estimated to be 1.5461 vs. 1.0297, 0.4759 vs. 0.1941, and 2.2885 vs. 0.4053 respectively. Price pervasive effects of the 10% increase in integrated-energy and manufactured gas supply sectors are computed to be 0.0127% and 0.1585%, respectively. This information can be utilized in forecasting the economic effects of introducing integrated-energy or manufactured gas as a heating source and the impacts of a rise in price of integrated-energy or manufactured gas on price level of other sectors.
