Objective : For the purpose of developing Korean herbalogy of the plants to Iridaceae in Korea, the literatures of the successive generations have been thoroughly investigated to prepare this article. Methods : The examined herbalogical books and research paper which published at home and abroad. Results : A list was made about Iridacease plant which are cultivated or grew naturally in Korea, after investigate the data on domestic and foreign Iridaceae plants. Out of those lists, serviceable plants were selected and with those available plants, their distributions were analysed and parts which can be used as medicines were divided into 3 categories such as oriental medicine name, scientific name and non-official name. Iridacease`s properties flavor, channels they use and effects were also noted, not to mention their toxicity. Iridacease (grew in Korea) was divided into 6 classes with 32 species. Out of those, 5 classes with 11 species were found serviceable which indicates 34% of all. Out of all 32 specified Iridacease plants, Iris plants were found 27 species, which were shown the most. And 7 classes of Iris plants were also selected the most in serviceable Iridacease. Out of all serviceable parts in Iridaceae, root parts took first place as 6 species. Conclusion ; There were totaled to 6 genera and 32 species in Iridaceae in Korea and among them medicinal plants are 5 genera, 11 species, some 34% in total.

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.
