Cells-In-Frames mechanism proposed by CIT in 1996 is an efficient way Local Area NETWORK-ATM NETWORK interconnection. According to this mechanism, connection oriented services are supported by connectionless UN workstations. In this technique ATM cells are carried by LAN frames. Each frame may include one or more A TM cells, but any given LAN frame is associated with only one ATM virtual circuit. There have not been any careful studies of Cells-In-Frames behavior since its proposal in 1996. In this paper the Cell-In-Frames mechanism for Ethenet LAN-ATM NETWORK interconnection is first implemented, then its PERFORMANCE for data transmission is studied from various points of views in order to highlight its strong and weak points. Finally a novel technique which greatly improves its PERFORMANCE is introduced. The simulation studies show that the new technique offers significant improvements at a very little hardware and software extra cost.

With the increase in environmental awareness, competitions and government policies, implementation of green supply chain management activities to sustain production and conserve resources is becoming more necessary for different organizations. However, it is difficult to successfully implement green supply chain (GSC) activities because of the risks involved. These risks alongside their resources disrupt the normal functioning of the GSC and affect its environmental and economic PERFORMANCE. The pharmaceutical industry in particular, is crucial to providing life-saving products and services to the society. The products and services provided in this industry, have several impacts on the environment in different ways. These include expired or unused medicines, inappropriate distribution by pharmacies or drug companies, disposal of surplus medicines in household sewage and improper disposal of pills or capsules by patients. This study represents a GSC risk NETWORK model that considers the interrelationships between risks in order to achieve an optimal level of PERFORMANCE measures defined in the supply chain by Bayesian Belief NETWORKs (BBN). The model is empirically implemented through a case study conducted in Imam Reza hospital of Mashhad medicine supply chain involving structured and semi-structured interviews and workshop sessions with experts. This work uses a literature review and a causal map BBN approach in finalizing the risks and also uses the BBN inference system and scenario analysis for prioritization and analysis of the risks through the NETWORK under probability conditions. According to the findings, inefficient logistics NETWORK design, supplier quality issues and green raw material supply disruption are highly prioritized.

Introduction: The importance of speed, synergy, and efficiency in service delivery has made the NETWORK paradigm the dominant paradigm for many government agencies, including the health care system. The purpose of the present study is to present a model of NETWORK PERFORMANCE evaluation in NETWORK governance of the Ministry of Health and Medical Education Methods: This was a qualitative content analysis study. Semi-structured interviews with exploratory orientation were conducted with 14 experts from the Ministry of Health and Medical Education. These were selected by purposive sampling. Content validity of extracted themes was 0. 90. Reliability between the two coders was 87%---------------------------------------------------------------------------------------------------------------------------------------------------------. Conclusion: In evaluating the PERFORMANCE of NETWORK governance, accountability and system stability are the most important factors. Health managers and policymakers can use the model provided in developing PERFORMANCE appraisal indicators.
