  • It was neede to know the amount of PAR to predict the growth of crops, and the quantity of total radiation to control the temperature by shading screen in the greenhouse. Experiments have been conducted to determine the correlation between the hourly PAR and total solar radiation the transmisson of PAR and total solar radiaiton oat canopy location, and the relationship between the illuminaance and total solar radiation. Additional experiments are needed to confirm thses experimental results.

  • 본 논문에서는 CORBA(Common Object Request Architecture)기반의 TINA(Telecommunications Information Networking Architecture) 분산체계에서 통신망 하부 장비들이 SNMP(Simple Network Management Protocol) 혹은 TMN(Telecommunications Management Network) 체계로 혼재되어 관리되는 네트워크의 NE(Network Element)들을 효율적으로 통합 관리할 수 있는 Generic Interface Adaptor(GIA)를 제안하고 이를 설계 및 구현하였다. GIA는 message mapping, protocol conversion 및 DBMS를 이용한 Object Abstract Translation(OAT)을 통해서 각 관리체계에 맞도록 관리정보를 변환시키며, 이를 통해 TINA EML(Element Management Layer) component와 SNMP NE agent 간의 상호연동을 가능하게 한다.
