  • 공시지가제 및 주택가격 공시제는 토지나 주택 거래를 위한 지가 정보나 국세 및 지방세의 과세를 위한 기초자료로 폭넓게 활용되고 있지만, 실제 시장에서는 공시가에 비해 낮은 현실화율을 보이고 있다. 본 연구는 이러한 개별공시지가와 주택실거래가 사이의 공간적 불일치에 주목하고 있으며, 특히 개별 공시가격 산정에 적용될 수 있는 임의적 공간 단위의 효과에 초점을 맞추어 다음 두 가지를 살펴보고 있다. 첫째, 개별공시지가, 주택실거래가, 그리고 이들의 가격 차이에 대한 공간적 분포를 집계구 단위를 기반으로 살펴본다. 둘째, 표준지나 표준주택에 대한 가격 산정, 나아가 개별공시지가나 주택가격에 대한 비준표 적용에 영향을 미칠 수 있는 공간 단위 임의성 문제(MAUP)의 스케일 효과를 탐색한다. 서울시를 대상으로 GIS와 통계 소프트웨어를 이용하여 분석하였고, 그 결과 주택실거래가가 개별공시지가에 비해 높은 일부 군집 지역들을 상세한 수준에서 발견할 수 있었으며, 상이한 공간 스케일에 따라 개별공시지가에 대한 지역 특성 변수들의 통계적 결과가 다르게 나타나고 있음을 실증적으로 확인하였다.

  • Objective: It is crucial to accurately determine the net energy (NE) values of feed ingredients because the NE system is expected to be applied to the formulation of broilers feed. The NE values of 5 wheat and 5 wheat brans were determined in 12-to 14-day old Arbor Acres (AA) broilers with substitution method and indirect calorimetry method. Methods: A total of 12 diets, including 2 reference diets (REF) and 10 test diets (5 wheat diets and 5 wheat bran diets) containing 30% of test ingredients, were randomly fed to 864 male AA birds with 6 replicates of 12 birds per treatment. These birds were used to determine metabolizable energy (ME) (8 birds per replicate) in the chicken house and NE (4 birds per replicate) in the chamber respectively at the same time. After a 4-d dietary and environment adaptation period, growth performance, energy values, energy balance and energy utilization were measured during the following 3 d. Multiple linear regression analyses were further performed to generate prediction equations for NE values based on the chemical components and ME values. The NE prediction equation were also validated on another wheat diet and another wheat bran diet with high correlation (r = 0.98, r = 0.75). Results: The NE values of 5 wheat and 5 wheat bran samples are 9.34, 10.02, 10.27, 11.33, and 10.49 MJ/kg, and 5.37, 5.17, 4.87, 5.06, and 4.88 MJ/kg DM, respectively. The equation with the best fit were NE = 1.968AME-0.411×ADF-14.227 (for wheat) and NE = -0.382×CF-0.362×CP-0.244×ADF+20.870 (for wheat bran). Conclusion: The mean NE values of wheat and wheat bran are 10.29 and 5.07 MJ/kg DM in AA broilers. The NE values of ingredients could be predicted by their chemical composition and energy value with good fitness.
