Information Model of Data Management in Network Online Educational Systems

Workflows to produce dental products by using CAD/CAM technology are very complex. Each patient needs an individual restoration. The challenge is to provide a patient individual production aiming at a price of mass production. But every single job has to run through an individual development as well manufacturing process. Typically, three stakeholders are involved in the workflow. The dentist performs the treatment and defines requirements for restoration. The dental laboratory plans the workflow and designs the reconstruction by using a dental CAD system. Subsequently, a milling center produces the restoration. Because of these highly heterogeneous workflows, diverse data streams and incompatibilities result. Often improper partners and resources are involved in the workflow. This fact is a significant source for errors. An additional complication is that errors are often discovered in late phases of the workflow. To avoid high costs and unacceptable delivery times, the aim is to develop a new concept for integrated workflow planning. The concept depends on three parts: Federative dental data management (FDDM) as a basic approach, including anticipated logic and structured activities. The federative data management provides a loosely coupling of heterogeneous systems crossing enterprise borders by using web technology. The FDDM service depends on APP technology. Each participant applies its specialized APP: FDDMz (dentist), FDDMd (dental laboratory) and FDDMf (milling center). FDDM services enable a continuously integrated workflow throughout the whole process of a patient individual production. Each participating enterprise is able to register its available processes and resources. Information about resources like 3D dental scanner or milling machines are able to add, according to a global data model schema. This schema depends on an integrated information model with eight partial models: Collaboration, resource, process, workflow, requirements, product, work preparation and production model. This integrated information model provides dental information including interlinked objects. Through a proper anticipation logic, conclusions about later phases can be anticipated already at early phases. The last conceptual part is workflow management on frame of structured activities. By combining the information network with the anticipation logic, filtering of appropriate partners, processes, resources and sequences is supported. Next, a prototypical implementation is demonstrated exemplarily. This concept delivers an important contribution to increase process reliability and quality as well as to reduce delivery times and costs for digital dental workflows.

Abstract This paper describes the information model and data management methods developed for the global database of a Concurrent Engineering environment for mechanical system design and evaluation. The environment considered has a CAD system and four CAE applications. The information model supports these engineering disciplines through multiple, unrestricted product composition hierarchies and a shared product definition. The dependency between the shared product definition and application models and between attributes of the parameterized, shared product definition are analyzed. The data management method employs a versioning policy that maintains consistent representations and history of the design as it undergoes design change transactions.

The complex engineering project has properties of long time lasting, enormous data amount and wide range of interoperation. To support effectively data management in both different product lifecycle phases and across different systems through web PDM system, ontology based product information model was developed. The model includes concept part for common manage and domain part for specific industries. Concepts and relations were built and introduced. Using ontology improved the machine interoperability. The developed model is validated by the application to the practical web PDM system of enterprise project.

Abstract. Economic changes in the context of globalization have left adolescents from Latin American contexts with few opportunities to make satisfactory transitions into adulthood. Recent studies indicate that there is a protracted period between the end of schooling and entering into formal working activities. While in this “limbo,” illicit activities, such as drug trafficking may emerge as an alternative for young people to ensure their social participation. This article aims to deepen the understanding of Brazilian youth’s involvement in drug trafficking and its intersection with their schooling, work, and aspirations, connecting with Sustainable Development Goals (SDGs) 4 and 16 as proposed in the 2030 Agenda for Sustainable Development adopted by the United Nations in 2015 .
