基于BIM技术的云计算信息园全生命周期参数化管理研究

Lifecycle Information Management of Cloud Computing Information Park Based on BIM

目前云计算信息园信息模型不完整，无法为全生命周期管理服务，因而有必要研究并建立更为完善的云计算信息园信息模型。研究云计算信息园的专业要素，可知其建筑信息模型、生产配套信息模型、工艺配套信息模型。为准确表达各类信息模型，采用参数化对各专业要素进行定义，包含坐标参数化、物理参数化、功能参数化、时间参数化、名称参数化。在参数化定义的构件和设备基础上，结合相应的信息团队建设，通过统一的信息平台对云计算信息园进行设计、施工、运行、维护、更新，从而实现云计算信息园全生命周期的信息化管理。通过合理的运行维护使资产取得最大化收益，从而使云计算信息园价值得到最大化。

Objective To investigate the efficacy of the ReCell@ techniques for healing of donor site in skin grafting. Methods Included in this study were a total of 30 patients, who were hospitalized in Burns Unit, the First Affiliated Hospital of Sun Yat-sen University between August 2011 and April 2012 and scheduled for free skin grafling. The patients were randomized into the study group （n=15） and the control group （n= 15）. For healing of the donor site, the study group received ReCell@ plus Urgo@, and the control group received Urgo alone. The patients were followed up until the end of post-operative 12 weeks. Between the two groups, we compared the severity of pain during the first wound dressing, time to wound healing, infections and the cosmetic outcomes. Results Compared with control group, the study group showed shorter healing time of the donor site[ （6.6±1.1） d vs （9.4±1.5） d, P〈0.01 ], milder pain at the first wound dressing （P〈0.05） and better cosmetic outcomes （P〈0.05）. There was no significant difference in the infection rate of donor site between the two groups （P〉0.05）, Conclusion ReCell@ can promote donor site healing and improve the healing quality of wound.
