The purpose of this study is to estimate the economic impacts of National Natural Recreation Forests using a regional input-output (I-O) model. Based on the regional I-O transactions tables developed by Bank of Korea (2009), National Natural Recreation Forests related sectional multipliers were derived with respect to output, income, employment, and value-added. Furthermore, surveys questioned National Natural Recreation Forests visitors in order to estimate per capita expenditures. The result shows that one National Natural Recreation Forests generated 3,380 million Won of output impact, 328 million Won of income impact, 1,017 million Won of value-added impact, and 22 full-time jobs within local effect, respectively. Also, one National Natural Recreation Forests generated 687 million Won of output impact, 85 million Won of income impact, 245 million Won of value-added impact, and 6 full-time jobs outside local effect, respectively.

This study examined the impact of changes in agricultural production methods on society, the economy, and the environment. While traditional open-field farming relied heavily on natural conditions, modern approaches, including greenhouse and smart farming, have emerged to mitigate the effects of climate and seasonal variations. Facility horticulture has been on the rise since the 1990s, and recently, there has been a growing interest in smart farms due to reasons such as climate change adaptation and food security. We compared open-field spinach and greenhouse spinach using agricultural income survey data, and we also compared greenhouse tomato cultivation with smart farming tomato cultivation, utilizing data from the smart farm survey reports. The economic results showed that greenhouse spinach increased yield by 25.8% but experienced a 29% decrease in income due to equipment depreciation. In the case of tomato production in smart farms, both yield and income increased by 36-39% and 34-46%, respectively. In terms of environmental impact, we also compared fertilizer and energy usage. It was found that greenhouse spinach used 29% less fertilizer but 14% more energy compared to open-field spinach. Smart farming for tomatoes saw a negligible decrease in electricity and fuel costs. Regarding the social impact, greenhouse spinach reduced labor hours by 31%, and the introduction of smart farming for tomatoes led to an average 11% reduction in labor hours. This reduction is expected to have a positive effect on sustainable farming. In conclusion, the transition from open-field to greenhouse cultivation and from greenhouse cultivation to smart farming appears to yield positive effects on the economy, environment, and society. Particularly, the reduction in labor hours is beneficial and could potentially contribute to an increase in rural populations.

This study estimates the economic impact of sea-level rise on Jeju island and suggests the optimal protection level based on the FUND model. There exist a number of studies that estimate the impacts of sea-level rise on global scale, but their results are of limited use for local scale such as Korea. Therefore, this study applies some specific indicators and data of Korea into to FUND model for deriving site specific estimates. The results show that 2.01%~2.25% of land could be inundated by sea-level rise until 2100. The value of affected land is about 6.4%~7.2% of total land value. The discrepancy between the figures indicates that the area affected by sea-level rise is much more valuable than the rest of Jeju island. The optimal protection level in Jeju city is higher than that in Seguipo city, even though the coastal length of Jeju city is longer than that of Seguipo. This is due to the fact that the economic value of Jeju city is much higher than that of Seoguipo city.

According to this study, overall economic impacts of the FTA between Korea and Singapore upon fish and fishery products of our country were likely to be very small and insignificant. When the tariff on fish and fishery products between the two borders were completely eliminated, if no roundabout exports from other ASEAN countries were practicing, then this study calculated that the increase of imports from Singapore in the 12 chief items was estimated to be only about 250,000kg, which comes to the amount of 1.1 billion won. The 12 items used here account for over 90% imports of fish and fishery products from Singapore. This study also revealed that imports of fish and fishery products from Singapore would be substituted for domestic products more than 100,000kg in the 7 items produced domestically. The substitution effect represents fishermen's demage by replacing domestic products by imports in terms of income which comes to the amount of 438 million won. As the results of the study shows, establishing an FTA between the two countries will not exert so much adverse effects on our fisheries because relative importance of fish and fishery products in both countries are very small. But the contents of the agreement on fish and fishery products between the two countries are very important, as concluding the negotiation and signing the agreement between Korea and Singapore would be a precedent in future negotiations with other asian countries, especially with China and ASEAN countries.

The article applies the ECM - ARDL model to examine the relationship between economic indicators and the existence of the disease in the long run of 10 ASEAN countries from 2000 to 2019. There are two models: The first model investigates the impact of GDP per capita, net inflow FDI, unemployment rate, and inflation rate on the proportion of export to GDP of ASEAN countries, the second model is similar to the first one but adds one more variable to the independent variable list - 'the variable for disease'. The results prove the long-run effect of GDP per capita, FDI, unemployment and inflation rate on export of the selected countries, though individual country shows differences in the sign and magnitude of these impacts. Surprisingly, the number of people suffering from disease does not affect the export of all selected countries as expected. The results of the two models also indicate that the disequilibrium in the short run converges to the equilibrium in the long run with a high proportion, especially in the case of Cambodia and the Philippines, with the rate of 95.65% and 151.94%, respectively. The findings can be useful for policymakers in promulgating efficient policies to enhance the trading activities of the selected countries.

Korean government has initiated integrated-energy business (IEB) in Mokdong for energy conservation in 1983. Since then, IEB has been steadily expanding. This paper attempts to apply input-output(I-O) analysis to examine the economic effects of IEB. A static I-O framework is employed, focusing on three topics in its application: the impact of the investment of IEB on the production of other sectors and the inter-industry linkage effect; supply shortage effects of the IEB ; and the impact of the rise in IEB rate on prices of other products. The paper pays closer attention to IEB sector by taking the sector as exogenous and then investigating its economic impacts. The results can be widely utilized in decision-making about IEB policy.

With the financial crisis from USA had negative impacts on the real economy, base metals price on LME was downward in 4 quarter of 2008. Following the deepest global downturn in recent history, economic growth solidified and broadened to advanced countries and simultaneously the price of base metal on LME showed a rising curve over 2009. There are three factors supported an upward tendency of base metal's price. The First factor is the US economy recovery, the second factor is the weak dollar, the third factor is the chinese base metal demand. Among the factors, the last one is a major factor. Therefore, this study analyze the factor of the movement of price of base metal with linear regression analysis. The result of analysis show that the chinese GDP growth has effect on the recent upward base metal price. Despite the result, the upward movement is difficult to be sustained without the full recovery of advanced economies.

This study examines how economic and psychological characteristics affect the quality of life (QoL) of elderly individuals age 60 and older, who live in the Seoul-metropolitan area. Relationships among socio-demographic status, economic conditions, psychological characteristics, family life, health status, and QoL are examined by t-test and ANOVA(Duncan's test as post hoc multiple comparisons), and the multiple regression analysis is used to estimate QoL determinants in the elderly. The major findings of the study are as follows. First, younger age, higher education levels, better health status, harmonious family relations, higher levels of household income, lower levels of loneliness, and higher self-esteems are related to higher QoL levels. Second, the impacts of factors on QoL are differentiated according to tercile groups that divide monthly allowance of respondents into three categories: below normal (threshold amount below 21MW), near normal (threshold amount between 21MW and 35MW), and above normal (threshold amount above 35MW). For each tercile group, poor health status or higher loneliness have negative effects on QoL, while harmonious family relationship has a positive effect. For the below-normal group, years of education or self-esteem have positive effects, while age or retirement status have negative effects when controlling for other factors. For the near-normal group, being married, or perceived financial insecurity create lower QoL levels, while higher self-esteem increases QoL levels. For the above-normal group, being widowed, employed, or retired have positive effects on QoL, when controlling for other variables. Third, even among elderly with high allowances, the effects of health status and family relationship are significant determinants that explain QoL levels. This result suggests that, for te elderly, poor health status and poor family relationships severely decrease QoL in later life, regardless of economic condition.
