계사시설, 환경관리, 시설자동화, 자동통제 및 전산화, 계분의 처리와 이용에 관해 검토해 보았다. 노후시설의 개선 또는 계사를 신축할 때는 다음과 같은 사항을 고려하여 계획을 세워야 한다. $\bullet$계사내부의 적정온도 유지를 위한 단열 $\bullet$자동급이 시설, 즉 사료탱크에서 체인 또는 링급이기로 사료의 자동이동 $\bullet$현재의 케이지에 가능한 자동집란 장치 $\bullet$여건이 적합하다면 자동화 케이지로 교체 $\bullet$노출된 급수통을 니플로 교체 $\bullet$계란 유통시 냉장이 완벽히 이루어지지 않는다면 계란 품질 보전을 위한 미네랄 코팅 $\bullet$계분처리방식중 노동력절감 및 공해방지 측면에서 가장 바람직한 형태를 선택 $\bullet$계사를 신축하는 경우 자동화 케이지 시스템과 계류장방식의 계분처리 체계의 선택을 신중히 검토 위와 같은 사항들은 산란계사 시설개선을 위한 의사결정에 도움을 줄 것으로 확신된다. 의사결정의 최종선택기준은 수익성에 있다!

To find a lateral long term behavior of driven H-piles in embankment, inclinometer is installed at pile and measurement is done during a year. When behavior of measured slope angles is in accord with behavior of nonlinear p-y curves(Reese, Murchison and O'Neil, Matlock's p-y analysis), maximum displacement of pile head, maximum stresses and maximum bending of pile obtained from the numerical analysis are shown. As results, maximum lateral displacement at pile head, maximum stress and maximum bending moment of pile are shown linear behavior. And maximum lateral load, maximum lateral displacement, and maximum bending moment at pile head obtained from the numerical analysis are 8∼12.4tonf, 9∼10.1mm, and 10.39∼12.67tonf-m per pile according to the curves, respectively.

The objectives of this study were to develop an image processing algorithm for finding the sick or the dead layers(SDL) rearing in the multi-tier layer battery, which is a core technology of remote monitoring systems for layers, and to test the performance of algorithm developed in the experimental poultry housing. Based on the literature study and experiment, the standing up of layer was set as a criterion for judging layers whether sick or dead. Then, by the criterion set, an algorithm was developed. The image processing algorithm developed was tested how well it could and SDL at the experimental poultry housing. Test results showed that its monitoring correctness of layers standing up in the cages having all healthy layers was $92\%$, and $96\%$ in the cages having SDL. Therefore, it would be concluded that the image processing algorithm developed in this study was well suited to the purpose of development.
