Calibration and Validation are major element of any space borne Earth Observation Mission. These activities are the major objective of the commissioning phases but routine activities shall be maintained during the whole mission in order to maintain the quality of the product delivered to the users or at least to fully characterise the evolution with time of the product quality. With the launch of ERS-l in 1991, the European Space Agency decided to put in place a group dedicated to these activities, along with the daily monitoring of the product quality for anomaly detection and algorithm evolution. These four elements are all strongly linked together. Today this group is fully responsible for the monitoring of two ESA missions, ERS-2 and Envisat, for a total of 12 instruments of various types, preparing itself for the Earth Explorer series of five. other satellites (Cryosat, Goce, SMOS, ADM-Aeolus, Swarm) and at various levels in past and future Third Party Missions such as Landsat, J-ERS, ALOS and KOMPSAT. The Joint proposal by the European Union and the European Space Agency for a 'Global Monitoring for Environment and Security' project (GMES), triggers a review of the scope of these activities in a much wider framework than the handling of single missions with specific tools, methods and activities. Because of the global objective of this proposal, it is necessary to put in place Multi-Mission Calibration and Validation systems and procedures. GMES Calibration and Validation activities will rely on multi source data access, interoperability, long-term data preservation, and definition standards to facilitate the above objectives. The scope of this presentation is to give an overview of the current Calibration and Validation activities at ESA, and the planned evolution in the context of GMES.

제조 생산 기업에서 도입하고 있는 MES (제조실행시스템: Manufacturing Execution System) 역시 이러한 시장 변화에 부응하기 위해 스마트화 및 IT융합화를 실현해야하는 현실에 놓여있다. 더욱이 최근 비즈니스 환경이 글로벌화(globalization) 됨에 따라 지역적으로 하나의 공장에서 제한적으로 생산되는 제품들이 다국적이고 분산적으로 생산하게 된다. 따라서 하나의 공장 운용 시스템을 관장하던 로컬(local) MES가 글로벌(global) MES 솔루션으로 확장되는 동시에, 로컬 MES간 생산 자원(production resource)을 상호 공유하는 시스템으로 변화되어야 한다.

GMES 는 유한차분시간영역 방법의 객체지향적 구현이다. 기존의 구현에선 점별(piecewise) 갱신방식을 사용해서 물성 표현 능력은 우수하지만, 계산 시간과 메모리 요구량에서 큰 약점이 있었다. 구분별(piecewise) 갱신 방식을 반영해 설계를 변경한 결과 물성 표현 능력은 기존과 같은 수준으로 유지하면서 70~90%에 이르는 계산 속도 개선과 사용 메모리 감소의 효과를 얻을 수 있었다.

Enterobacter cloacae (strain PR2/7), a genetically modified endophyte(GME) in citrus plants, carrying different plasmids (pEC3.0/18, pCelE, pEglA and pGFP), was inoculated into Citrus sinensis seedlings under greenhouse conditions. The impact of this on the indigenous bacterial endophytic community was studied by analyses of 2 different morphologic groups. The germination rates of inoculated seeds were evaluated in greenhouse, and plasmid stability under in vitro conditions. Results demonstrated a great and diverse endophytic community inside plants, and specialization in tissue colonization by some bacterial groups, in different treatments. Shifts in seed germination rate were observed among treatments: in general, the PR2/7 harboring pEglA bacterial- clone significantly reduced seed germination, compared to the PR2/7 harboring pEC3.0/18 clone. This suggests that the presence of the pEglA plasmid changes bacteria-seed interactions. The endophytic community of citrus seedlings changed according to treatment. In seedlings treated with the PR2/7 with pEglA clone, the population of group II decreased significantly, within the context of the total endophytic community. These results indicate that the application of GMEs induces shifts in the endophytic bacterial community of citrus seedlings.
