Large scale flood disasters bring human losses and properties, which lead to the decrease of our productive value and change social environment. Human loss and economic damage are considered to be the same system but they are viewed as separated systems. The total amount of human loss can be represented as the total amount of economic damage estimated in the frame of social system while it will be possible to make mutual changing by clearing the relations between social and economic systems. In this regard, an attempt to estimate economic loss considering per capita Gross Domestic Production (GDP) caused by flood-related mortality was carried out to the typhoon Rusa of 2002 in Kangwon-do. The proposed method tried to capture quantitative factors which are affecting the loss of per capita GDP. The approach has great importance not only to set up governmental policy but also methodological progress in the research due to impact of disaster-related mortality on GDP loss.

The gross domestic product(GDP) measures the welfare of a nation's economy through the aggregation of products and services produced in a nation. Although GDP is a proficient measure of the magnitude of the economy, many economists, environmentalists, and citizens have recently criticized the gross domestic product. The criticism stems from the fact that this measurement of domestic product does not account for environmental degradation and resource depletion. We need to estimate the environmentally adjusted net domestic product. The gross domestic product was 913 trillion won while environmental protection expenditure was 32.9 trillion won by monetary accounts of Korea, 2010. Loss of natural assets was 76.6 trillion emwon by emergy analysis of Korea, 2010. The Green GDP was accounted for 88.0% of the GDP to 803.5 trillion won.

This study has developed Computable General Equilibrium (CGE) model reflecting endogenous growth economic theory, with the aim of analyzing double dividend hypothesis. This study analyzes possibility of economic growth and environmental improvement at the same time when government recycles the revenue of carbon tax to reduce existed taxes such as consumption tax, labor income tax, corporate tax. It also assesses the case of subsidy on R&D investment of renewable energy. With new and renewable generation technology adopted and disseminated, GDP loss would be lessened to a great degree. Tax recycling would provide economic gain by reducing distortion existed in the existing fiscal structure. The magnitude of economic gains from carbon tax recycling is biggest for recycling into corporate tax, and labor income tax, and then consumption tax in this order. It is also shown that double dividend effects occur in dynamic terms when government uses a carbon tax revenue to subsidize on R&D investment. At the end of the analysis period, emissions reduction would not result in GDP loss but in GDP gain. In particular, recycling into R&D increase would produce the largest and fastest GDP gain. Thus, implementing emissions reduction target would require careful consideration of economic effects by various policy instrument, including carbon tax.

Corrosion of metallic materials occurs by the reaction with corrosive environment such as atmosphere, marine, soil, urban, high temperature etc. In general, reduction of thickness and cracking and degradation are resulted from corrosion. Corrosion in all industrial facilities and infrastructure causes large economic losses as well as a large number of accidents. Economic loss by corrosion has been reported to be nearly 1-6% of GNP or GDP. In order to reduce corrosion damage of industrial facilities, corrosion map as well as a systematic investigation of the loss of corrosion in each industrial sector is needed. The Corrosion Science Society of Korea in collaboration with 15 universities and institutes has started to survey on the cost of corrosion and corrosion map of Korea since 2005. This work presents the results of the survey on cost of corrosion by Uhlig, Hoar, and input-output methods, and the evaluation of atmospheric corrosion rate of carbon steel, weathering steel, galvanized steel, copper, and aluminum in Korea. The total corrosion cost was estimated in terms of the percentage of the GDP of industry sectors and the total GDP of Korea. According to the result of Input/output method, corrosion cost of Korea was calculated as 2.9% to GDP (2005). Time of wetness was shown to be categories 3 to 4 in all exposure areas. A definite seasonal difference was observed in Korea. In summer and fall, time of wetness was higher than in other seasons. Because of short exposure period (12 months), significant corrosion trends depending upon materials and exposure corrosion environments were not revealed even though increased mass loss and decreased corrosion rate by exposure time.

Objectives: We wanted to estimate the annual socioeconomic costs of alcohol drinking in Korea. Methods: The costs were classified as direct costs, indirect costs and the other costs. The direct costs consisted of direct medical costs, indirect medical costs and subsidiary medical costs. Particularly, the medical costs and population attributable fraction for disease were considered to reflect the calculation of the direct medical costs. The indirect costs were computed by the extent to which the loss of productivity and loss of the workforce might have occurred due to changes in mortality and morbidity according to alcohol drinking. The other costs consisted of property loss, administration costs and costs of alcoholic beverage. Results: The annual costs, which seemed to be attributable to alcohol drinking, were estimated to be 149,352 hundred million won (2.86% of GDP). In case of the latter, the amount includes 9,091 hundred million won for direct costs (6.09%), 62,845 hundred million won for the reduction and loss of productivity (42.08%), 44,691 hundred million won for loss of the workforce (29.92%), and the other costs (21.91%). Conclusions: Our study confirms that compared with the cases of Japan (1.9% of GNP) and the other advanced countries (1.00-1.42% of GDP), alcohol drinking incurs substantial socioeconomic costs to the Korean society. Therefore, this study provides strong support for government interventions to control alcohol drinking in Korea.

This study estimated the socioeconomic costs of child poverty. Based on previous studies, the present study organized component categories for direct and indirect costs of child poverty, and estimated the cost of each category in 2015 through the collection of existing data and Delphi survey techniques among experts. The total socioeconomic costs of child poverty were compared to Korea's GDP. The results of this study were as follows. First, the socioeconomic costs of child poverty in Korea in 2015 ranged from 55 trillion KW(3.5% of GDP) to 99 trillion KW(6.5% of GDP). Second, the indirect socioeconomic costs of child poverty are much higher than the direct costs. Third, among the total cost categories, costs related to productivity loss and unemployment accounted for the largest portion of both the socioeconomic costs based upon absolute poverty and relative poverty. Crime costs are the second largest. Based on these results, we discussed the importance of early intervention for children in poverty; implementation of two-generation program that intervenes simultaneously with parents and children; and long-term, continuous and integrated intervention for high-risk groups such as poor children.

For child abuse prevention in Korea, this study estimated the socioeconomic costs of child abuse. Based on previous studies, the present study organized component categories for estimable direct and indirect costs of child abuse, and estimated the cost of each category in 2014 through the collection of existing data and through Delphi survey techniques among experts. The total socioeconomic costs of child abuse were compared to Korea's GDP. The results of this study were as follows. First, the socioeconomic costs of child abuse in Korea in 2014 ranged from 389.9 billion KW(0.03 percent compared to GDP) to 76 trillion KW(5.1 percent compared to GDP). Second, the indirect socioeconomic costs of child abuse are much higher than the direct costs. Third, costs related to productivity loss and unemployment accounted for the largest proportion of the total costs. In addition, the proportion of the child protection budget in Korea was very low compared to developed countries. These findings suggest that there is a need to increase Korea's child protection budget and to take urgent action to detect unrevealed child abuse cases. Furthermore, in order to reduce indirect costs, it is important to provide abused children with early professional treatment.

Remote Sensing Monitoring and Loss Estimated System of Flood Disaster based on GIS is an integrated system comprised flood disaster information receiving and collection, flood disaster simulation, and flood disaster estimation. When the system receives and collects remote sensing monitoring and conventional investigation information, the distributional features of flood disaster on space and time is obtained by means of image processing and information fusion. The economic loss of flood disaster can be classified into two pus: direct economic loss and indirect economic loss. The estimation of direct economic loss applies macroscopic economic analysis methods, i.e. applying Product (Industry and Agriculture Gross Product or Gross Domestic Product - GDP) or Unit Synthetic Economic Loss Index, direct economic loss can be estimated. Estimating indirect economic loss applies reduction coefficient methods with direct economic loss. The system can real-timely ascertains flood disaster and estimates flood Loss, so that the science basis fur decision-making of flood control and relieving disaster may be provided.

Most studies on $CO_2$ abatement cost with a computational general equilibrium(CGE) model focus on a specific country. On the contrary, this study compares and analyses the $CO_2$ abatement cost functions across 20 countries, consisting of OECD countries, China and Brazil, with a CGE model. For this purpose, we estimate the GDP loss from $CO_2$ emission reduction, assuming the 4 sector model. Our findings show that those cost curves are convex but different among the countries. However, despite of the difference in the cost curios, we have found that one group of countries has the relatively constant average abatement cost and the other group has the increasing average cost. The reason why such a pattern occurs is explained in terms of the variations of value-added and $Co_2$ emission coefficient by sector across the countries. As an environmental policy implication, this study presents information about which country is similar to one another in terms of the abatement cost.

We use a multi-regional dynamic computable general equilibrium model to explain an economic effect of $CO_2$ tax on the national and regional economy of Korea. First, we compare two $CO_2$ taxes: a region-specific $CO_2$ tax and a uniform $CO_2$ tax. In the region-specific tax, the $CO_2$ tax rate in the capital area and the south-eastern region is much greater than those in other regions. GDP loss resulting from the region-specific tax is bigger than that in the uniform tax. Second, we consider three options for tax recycling: consumption tax recycling, labor-income tax recycling, and corporate-income tax recycling. The corporate-income tax recycling has the least GDP-loss effect over the three options. These results support that it is more efficient to use a uniform $CO_2$ tax rate than a region-specific $CO_2$ tax rate and that the corporate-income tax recycling is more desirable in a sense of efficiency than the consumption and labor-income tax recycling options.
