The system designed in this paper, can mark the interior state of greenhouse using sensors of temperature, humidity and illumination on greenhouse interior by greenhouse system for farm village area's agriculture automation. And, the real time monitor is possible real time monitoring by camera. Also, system that can supply water using spring cooler system and humidifier. The proposed system can sustain a designed environment of the greenhouse through rentilation fan, fluorescent light and roof door control. TCP/IP is used for the remote control of state the sensors in the client program. 본 논문에서 설계된 시스템은 농촌 지역의 농업 자동화를 위한 온실 시스템으로 온실 내부에 온도, 습도, 조도 센서를 이용한 온실 내부의 상태를 표시할 수 있으며 카메라를 이용하여 실시간 관측이 가능하다. 또한 본 시스템은 지붕 개폐, 스프링 쿨러와 가습기를 이용한 수분 공급, 환풍기, 형광등 등을 통하여 온실 내부의 환경을 유지시킬 수 있다. 모든 센서를 이용한 상태와 온실 제어를 TCP/IP를 이용한 클라이언트 프로그램에서 원격으로 관리할 수 있다.

This experiment was designed to observe the early pathologic changes induced by local Co-60 γ-ray irradiation in the lung and to investigate the mechanism of that changes. Co-60 γ-ray(500, 750 and 1,000 rad) was locally irradiated to the right lung of Sprague Dawley rats. After irradiation, the rat lungs were isolated at intervals of 12 hours, 1 day, 3 days, 1 week, 2 weeks, and 3 weeks, respectively. Histological(hematoxylin-eosin, Masson's trichrome, van-Gieson, and reticulin stain) and enzyme histochemical(acid phosphatase, alkaline phosphatase, and nonspecific estease stain) findings were observed and the foolowing results were obtained: 1. After Co-60 γ-ray irradiation, alveolar hemorrhage, exudation and perivascular infiltration of inflammatory cells were developed more rapidly in proportion to the dose of irradiated Co-60 γ-ray at early stage. 2. After Co-60 γ-ray irradiation, the number of alveolar macrophasges in the alveolar wall and histiocytes in the alveolar septum were decreased at early stage, but it showed some evidences of restoration after 1 week. 3. One week after irradiation, denudation of the cells of the alveolar wall was appeared. The majority of which were alveolar macrophages. And these cells were appeared as abnormal giant cells in the large dose irradiated droup. 4. In the large dose irradiated group, some of the bronchial epithelial cells were changed to squamous epithelium from 1 week after irradiation. 5. In the enzyme histochemical findings, acid phosphatase, alkaline phosphatase and nonspecific esterase showed little difference in the irradiated dose or the duration of irradiation. These obervations permit the conclusion that the mechanism of early pathologic changes in the lung induced by irradiation is an inflammatory changes due to increased vascular permeability, and the degree of inflammatory changes is proportional to the irradiated doses. And the cell damage induced by irradiation is directly proportional to the degree of differentiation.
