This study is designed to measure the relative efficiency of regional fishery cooperatives based on Data Envelopment Analysis(DEA) methods. Selecting 40 regional fishery cooperatives in Busan as Decision Making Units (DMUs), the study uses their panel data from 2007 to 2008 to rank the relative efficiency of the DMUs. First, the efficiency score of the DMUs are calculated using CCR, SBM, and super-SMB model. Within the model, input variables are the number of employees and area of fishery cooperatives. Output variables are the amount of deposit money, loan and profit. Based on the efficiency scores calculated from super-SMB model, the efficiency ranking of the DMUs is determined. Second, the differences in average efficiency calculated from the three DEA models are tested using a pair-wise mean comparison test. The results based on the efficiency scores evaluated from super-SMB model show that seven out of the forty DMUs are efficient; among the efficient DMUs, the DMUs that can be benchmarked for inefficient DMUs through the frequency analysis of reference set being identified. Third, the differences in average efficiency of the three DEA models between 2007 and 2008 are tested using pair-wise mean comparison test and the study estimates the efficiency change of the DMUs between 2007 and 2008 using Malmquist productivity index(MPI). Finally, the paper suggests an improved composite DMU superior to the inefficient DMUs evaluated by Super-SBM model.

농업 생태계는 주요 온실가스의 배출원 중 하나로, 농경지에서의 온실가스 배출량을 최소화하면서 최적의 수량을 얻기 위한 기후변화 적응옵션을 도출하기 위해서는, 상세한 공간적 규모에서 여러 모형들을 연계하여 구동하는 것이 유리하다. 본 연구에서는 DSSAT 모형과 DNDC 모형을 연계하여 상세한 공간 규모에서 기후변화 영향평가를 수행할 수 있도록 지원하기 위한 도구를 개발하고자 하였다. 객체 지향 언어인 R과 C++을 사용하여 DNDC 모형의 격자형 입력자료를 생성하기 위한 DRIFT (DNDC Regional Input File Tool)을 구현하였다. 기후변화 조건에서 격자별 작물 생육모의를 위해 생성된 DSSAT 모형의 입력자료 및 출력자료를 사용하여 DNDC 모형의 입력자료를 생성하였다. 생성된 입력자료를 사용하여 미래 기후변화 조건에서의 온실가스 배출량을 모의하였다. 입력자료를 생성하는 시간은 격자 지점의 수에 비례하여 증가하였다. 그 중, DSSAT 모형의 담수 깊이 자료를 DNDC 모형의 담수 기간으로 변환하는 과정에서 시간이 비교적 오래 걸렸으나, 그 외의 입력자료를 생성하는 데에는 짧은 시간만이 소요되었다. 본 연구에서는 비교적 적은 지점을 대상으로 하였으나, 대량의 자료를 처리하고자 할 경우 일부 계산과정을 병렬화함으로써 구동시간을 줄일 필요가 있을 것이다. 이후 다른 모형들에 대한 확장을 통해 모형 간 연계를 위한 입력자료 생성에 소요되는 시간을 줄일 수 있을 것이다.

Recently, the demand of rural tourism has been increased to promote farm household income and rural economy. Korean government has supported to promote rural tourism. One of the most difficult tasks in estimating the economic impact of the tourism industry is how the industry should be defined in terms of an economic sector, since tourism is not defined in national Input-Output (I-O) tables or in the Standard Industrial Classification code. Moreover, there is no specified Standard Industrial Classification for rural tourism. The purpose of the study aims to examine specified Standard Industrial Classification of rural tourism using the I-O model analysis to estimate the economic impacts of rural tourism. Results showed that there were two components considered as inputs. One is the inputs that final demand can move to input of rural tourism in I-O tables. The other is one that the final demand was provided by farm household as intermediate inputs.

It is generally believed that there is a trade-off between economic growth and environmental quality since pollutants are generated in the process of production and consumption of commodities. Several researchers have shown this prevailing belief using the short-term input-output models. The literature, however, shows that there have been few attempts to investigate the relationship using long-term forecasting models. This motivates the current paper. This paper attempts to build a reginal growth model in a partial equilibrium framework taking into consideration the requirements of capital invested for pollutant abatement. Model is largely neoclassical. Labor is assumed to move a region with high utility specified in regional per capita average was income and pollution level while capital is partially mobile to a region with high returns. The regional growth is explored in a phase diagram. The paper shows that there are two stable growth equilibria which a region can converge over time and that the equilibria are distinguished by the initial threshold capital stock that a region holds. If the initial capital stock of a region is over(under) than the threshold size, the region converges to the higher (lower) growth equilibrium over time. Moreover, based on this result an environmental quality enhancing policy is analyzed in the phase diagram. It has revealed that the policy calls for the relocation of growth equilibrium points, specifically speaking, it stimulates an increase in labor stock and a decrease in capital stock. Hence the paper has suggested that the prevailing belief which the environmental policy negatively impacts on a regional economic growth is not always true.

The black box model is a relatively new option for nonlinear dynamic system identification. It can be used for prediction problems just based on analyzing the input and output data without considering the changes of the internal structure. In this paper, a black box model was presented to solve unconstrained overlying strata movement problems in coal mine production. Based on the black box theory, the overlying strata regional system was viewed as a "black box", and the black box model on overburden strata movement was established. Then, the rock mechanical properties and the mining thickness and mined-out section area were selected as the subject and object respectively, and the influences of coal mining on the overburden regional system were discussed. Finally, a corrected method for height prediction of the fractured zone was obtained. According to actual mine geological conditions, the measured geological data were introduced into the black box model of overlying strata movement for height calculation, and the fractured zone height was determined as 40.36 m, which was comparable to the actual height value (43.91 m) of the fractured zone detected by Double-block Leak Hunting in Drill. By comparing the calculation result and actual surface subsidence value, it can be concluded that the proposed model is adaptable for height prediction of the fractured zone.
