본 연구는 포장모형(APEX, Agricultural Policy Environmental eXtender)과 유역모형(SWAT, Soil and Water Assessment Tool)을 연계하여 새만금 유역의 미래 수문 수질영향과 용수생산성을 분석하기 위한 기초연구이다. APEX 모형을 연계하기에 앞서 SWAT 모형을 이용하여 만경강 유역의 유출량, T-N, T-P를 모의하고 그 적용성을 평가하였다. 모의 기간은 2004년부터 2017년까지 총 14년이며, 기상, 유출량 그리고 월단위 수질 자료를 모형의 입력자료 및 보정을 위해 사용하였다. 매개변수 보정은 객관적 보정이 가능한 SWAT-CUP을 이용하여 최적화 하였으며, 매개변수 보정의 목적함수는 NSE(Nash-Sutcliffe Efficiency)로 평가하였다. 모형의 적용성 평가 결과, 보정기간의 연평균 유출량은 실측치 835mm, 모의치 677mm로 나타났고, R2는 0.64, RMSE는 3.87mm/day, NSE는 0.61, RMAE는 0.99로 나타났다. 검정기간의 연평균 유출량은 실측치 884mm, 모의치 702mm로 나타났고, R2는 0.67, RMSE는 2.92mm/day, NSE는 0.7, RMAE는 0.94로 나타났다. 유출량의 결과를 살펴보면 검정기간이 보정기간보다 모의결과가 더 나은 것으로 나타나며, 이는 실측자료의 일관성 차이로 판단된다. T-N과 T-P의 경우 매개변수만으론 보정의 한계가 있으며, 실측치와 근접하게 모의하기 위해서 만경강 본류에 영향을 끼칠 수 있는 외부유입량을 고려할 필요가 있다. 따라서 본 연구에서는 만경강 상류의 경천댐, 대아댐 그리고 용담댐으로 부터 유입되는 외부유입량 자료를 수집하여 SWAT의 입력자료로 구축하였으며, 대상유역 내 익산, 완주, 전주, 김제에 위치하고 있는 하수처리장, 축산폐수처리장, 분뇨처리시설, 산업폐수처리시설 그리고 농공단지처리시설 등 총 12곳에 대한 점오염원 데이터를 입력자료로 구축하여 만경강 상류 농업소유역의 수질영향을 평가하였다. 본 연구결과는 향후 미래 수문 수질 모의에 대한 기초자료로 제공될 것이며, 외부유입량을 고려한 만경강 유역의 용수생산성 분석을 통해 미래 농업수자원 관리계획 수립에 활용할 수 있을 것이다.

In general, quantity results of empirical analysis using model shows how much big performance policy has. Therefore this is useful to evaluate a policy. This paper composed macro economic model based on Bank of Korea's quarterly model and annual model, that estimates performance of overseas oil and gas development project to Korean economy in aspect of quantity. In this model, we estimated each effect in real GDP, current account, unemployment rate, CPI and exchange rate carried by recovered amount from overseas oil and gas development project. The recovered amount was evaluated in currency coming from oil and gas acquired from overseas oil and gas development project. Macro economic model of this paper benchmarked macro model composed by Bank of Korea(1997, 2004, 2012). We reviewed model robustness using statistical suitability of each equation and historical simulation for from 1994 to 2011. The recovered amount of overseas oil and gas development project has positive effect in every macro economic index except CPI and exchange rate. Economic effect to macro economic index become bigger with time because the recovered amount of overseas oil and gas development project are increasing until now. Although empirical results of economic effects in every year from the recovered amount of overseas oil and gas development project are different, as of 2011, empirical results showed that the recovered amount of overseas oil and gas development project increase 2.226% and 0.401% in current account and real GDP respectively. And it also decrease 0.489%p in unemployment rate. Exchange rate to US dollars also decrease in amount of 0.379%.

Introduction: Diffusion is process by which an innovation is communicated through certain channel overtime among the members of a social system(Rogers 1983). Bass(1969) suggested the Bass model describing diffusion process. The Bass model assumes potential adopters of innovation are influenced by mass-media and word-of-mouth from communication with previous adopters. Various expansions of the Bass model have been conducted. Some of them proposed a third factor affecting diffusion. Others proposed multinational diffusion model and it stressed interactive effect on diffusion among several countries. We add a spatial factor in the Bass model as a third communication factor. Because of situation where we can not control the interaction between markets, we need to consider that diffusion within certain market can be influenced by diffusion in contiguous market. The process that certain type of retail extends is a result that particular market can be described by the retail life cycle. Diffusion of retail has pattern following three phases of spatial diffusion: adoption of innovation happens in near the diffusion center first, spreads to the vicinity of the diffusing center and then adoption of innovation is completed in peripheral areas in saturation stage. So we expect spatial effect to be important to describe diffusion of domestic discount store. We define a spatial diffusion model using multinational diffusion model and apply it to the diffusion of discount store. Modeling: In this paper, we define a spatial diffusion model and apply it to the diffusion of discount store. To define a spatial diffusion model, we expand learning model(Kumar and Krishnan 2002) and separate diffusion process in diffusion center(market A) from diffusion process in the vicinity of the diffusing center(market B). The proposed spatial diffusion model is shown in equation (1a) and (1b). Equation (1a) is the diffusion process in diffusion center and equation (1b) is one in the vicinity of the diffusing center. $$\array{{S_{i,t}=(p_i+q_i{\frac{Y_{i,t-1}}{m_i}})(m_i-Y_{i,t-1})\;i{\in}\{1,{\cdots},I\}\;(1a)}\\{S_{j,t}=(p_j+q_j{\frac{Y_{j,t-1}}{m_i}}+{\sum\limits_{i=1}^I}{\gamma}_{ij}{\frac{Y_{i,t-1}}{m_i}})(m_j-Y_{j,t-1})\;i{\in}\{1,{\cdots},I\},\;j{\in}\{I+1,{\cdots},I+J\}\;(1b)}}$$ We rise two research questions. (1) The proposed spatial diffusion model is more effective than the Bass model to describe the diffusion of discount stores. (2) The more similar retail environment of diffusing center with that of the vicinity of the contiguous market is, the larger spatial effect of diffusing center on diffusion of the vicinity of the contiguous market is. To examine above two questions, we adopt the Bass model to estimate diffusion of discount store first. Next spatial diffusion model where spatial factor is added to the Bass model is used to estimate it. Finally by comparing Bass model with spatial diffusion model, we try to find out which model describes diffusion of discount store better. In addition, we investigate the relationship between similarity of retail environment(conceptual distance) and spatial factor impact with correlation analysis. Result and Implication: We suggest spatial diffusion model to describe diffusion of discount stores. To examine the proposed spatial diffusion model, 347 domestic discount stores are used and we divide nation into 5 districts, Seoul-Gyeongin(SG), Busan-Gyeongnam(BG), Daegu-Gyeongbuk(DG), Gwan- gju-Jeonla(GJ), Daejeon-Chungcheong(DC), and the result is shown
