It also makes an analysis of the basic and improved PAC (Production Activity Control) Architecture in the Control System for Integrated Manufacturing. The PAC Architecture and the improvement will further enhance the flexibility and adaptability of the architecture in the ever changing environment of the Shop Floor Control (SFC) Systems.展开更多

Weaknesses of the production activity control （PAC） architecture of the shop floor are addressed by the Maglica＇s new system architecture. This architecture gives rise to unlimited number of movers and producers thus evolving more complex but decentralized architecture. Beijing Institute of Technology - production activity control （BIT-PAC） architecture introduces an idea of sub-producars and sub-movers thus reducing the complexity of the architecture. All the equipments including sub-producars and sub-movers are considered to be passive in the proposed shop floor information system. The dissemination of information from sub-producers and sub-movers is done manually through a PC. Proposed BIT-PAC SFC architecture facilitates the information flow from shop floor to the other area of the organization. Effective use of interact information services （IIS） and SQL2000 is done along with the ASP.NET technology to implement the application logic. Applicability of the software based on BIT-PAC architecture is checked by running application software on a network PC that supports the dynamic flow of information from sub-producers and sub-movers to the other parts of the organization. Use of software is also shown at the end for BIT training workshop thus supporting the use of SFC architecture for similar kind of environments.展开更多

The success of the new construction products calls for a high-quality and well-managed product development process. Thus, this study aims at defining the basic steps of a NPD （new product development） process designed for floor coverings and evaluating its applicability. To this end, the product development methods of the leading companies in the construction sector in Turkey have been analyzed. Also, a questionnaire has been conducted to determine which of the steps of the proposed methodology are currently being realized and which are not or cannot be implemented. Finally, based on this information, certain suggestions have been made as to what can be done to enhance the NPD processes of the companies＇ subject to evaluation.展开更多

The BIT-PAC architecture has been applied with the use of information technology. It facilitates the information flow from Shop Floor to other areas of the organization and makes the organizations more integrated and productive. This architecture also facilitates the expansion of the Shop Floor functions without disturbing the basic infrastructure. Effectiveness of the BIT-PAC architecture was checked by developing and running application software on a network PC which has supported the dynamic flow of information from Sub-Producers and Sub-Movers to other areas of organization.展开更多

For the radiation of sunlight is identical in the same unit area of the same latitude, we could not increase the productivity by changing the total radiation, but we can change the property of the floor by setting up effect be1ts and develop the structure of community and the photosynthetic system. In the end, significant benefits on productivity and biological, ecological effects were showed by 30 years experiments.展开更多
目的:研究硬膜外麻醉分娩镇痛对初产妇生产指标和盆底功能的影响。方法:选取2021年2月—2022年5月在湖北理工学院附属黄石爱康医院分娩的80例初产妇作为研究对象,采用随机数表法分为试验组和对照组,各40例。对照组采用自然待产分娩,试...目的:研究硬膜外麻醉分娩镇痛对初产妇生产指标和盆底功能的影响。方法:选取2021年2月—2022年5月在湖北理工学院附属黄石爱康医院分娩的80例初产妇作为研究对象,采用随机数表法分为试验组和对照组,各40例。对照组采用自然待产分娩,试验组采用硬膜外麻醉分娩镇痛。比较两组生产指标、镇痛效果、盆底功能差异。结果:试验组的阴道分娩率高于对照组,中转剖宫产率低于对照组,差异有统计学意义(P<0.05);试验组的第一产程、总产程时间短于对照组,差异有统计学意义(P<0.05);试验组的产后疼痛程度轻于对照组,差异有统计学意义(P<0.05);分娩后42 d,试验组的盆底肌力强度优于对照组,差异有统计学意义(P<0.05)。结论:硬膜外麻醉分娩镇痛能有效改善初产妇分娩方式,不会对初产妇产后2 h出血量、新生儿1 min Apgar评分、会阴撕裂率、会阴侧切率造成影响,同时积极改善初产妇的盆底功能。展开更多
