During the last years it has become more and more common practice in the gear industry to exchange gear data electronically between the different parties. Up to now the format of the gear data is usually DXF, IGES or a company-specific format. A common format, which includes not only geometry data, but also load capacity and other gear-related data, was not available. Therefore a product model for gear units was developed at the FZG (Forschungsstelle fuer Zahnraeder und Getriebebau). The main goal was the realization of the data exchange between gear calculation programs, CAD-systems and a central storage of all gear data. This product model covers all kinds of gear data like gear geometry, load capacity data, lubricant data, manufacturing data, etc.. The product model for gear units is based on the application protocol AP 214 of ISO 10303 STEP. This application protocol was originally created to describe the design process of the automotive industry and does not have a sufficient definition of gear data. An extension of an existing application protocol causes time consumptive normative procedures. Therefore the structure of the product model for gear units is independent from ISO 1030-214. It consists of a mechanism, which defines a data structure acc. to ISO 10303-214, but adapted to the product model for gear units. The product model gives a description how to use ISO 10303-214 for the application of gear units. Meanwhile this product model for gear units is published as a VDMA-paper and therefore open to the public. The first successful application is the data exchange between gearcalculation programs of the FVA and CAD-systems. By this new format the data exchange of gear data is now extremely simplified.

Industries are continuously trying to improve the time to market through automation and optimization of existing product development processes. Large companies vow to save significant time and resources through seamless communication of data between design, manufacturing, supply chain and quality assurance teams. In this context, Model Based Definition/Engineering (MBD) / (MBE) has gained popularity, particularly in its effort to replace traditional engineering drawings and documentations with a unified digital product model in a multi-disciplinary environment. Widely used 3D data exchange models (STEP AP 203, 214) contains mere shape information, which does not provide much value for reuse in downstream manufacturing applications. However, the latest STEP AP 242 (ISO 10303-242) “Managed model based 3D engineering” aims to support smart manufacturing by capturing semantic Product Manufacturing Information (PMI) within the 3D model and also helping with long-term archival. As a primary, for interoperability of Geometric Dimensions & Tolerances (GD&T) through AP 242, CAx Implementor Forum has published a set of recommended practices for the implementation of a translator. In line with these recommendations, this paper discusses the implementation of an AP 203 to AP 242 translator by attaching semantic GD&T available in an in-house Constraint Tolerance Graph (CTF) file. Further, semantic GD&T data can be automatically consumed by downstream applications such as Computer Aided Process Planning (CAPP), Computer Aided Inspection (CAI), Computer Aided Tolerance Systems (CATS) and Coordinate Measuring Machines (CMM). Also, this paper will briefly touch base on the important elements that will constitute a comprehensive product data model for model-based interoperability.

Today, a company continues its activities in a highly competitive environment regardless of the sector in which it operates. An important point has been emphasized in many developments by experienced managers and academics which have been released to the public. From marketing to finance, human resource management, auditing and planning, all business processes have entered an incredible innovative process. One of the topics in this process is big data. When cumulative data are not used, they cannot transcend being huge piles of garbage. However, it is not possible to analyze such large, complex, and dynamic data via conventional methods. At this point, the concept of big data has emerged. In this study, after the explanation and definition of the concept, a vast literature review was conducted in order to present the relationship of big data with IoT, big data-related topics, and academic researches on big data. Afterwards, real-life enterprise applications were exemplified from various industries.

This paper reports some aspects of the work being carried out on the NEUTRABAS project under the ESPRIT II European research program. The aim of this project is to specify and implement a neutral product definition database for large marine-related artifacts, covering a large part of the complete product life-cycle. The results of this research program will facilitate the effective exchange of product related data between disparate computer-based information systems, and hence promote a movement towards product life-cycle integration. The scope of the product model being developed as the basis for this integration is described in terms of its spatial and steel structural components, together with the implications for integration with other models of outfitting and engineering systems. The model is shown to encompass the wide range of product-related data which is associated with the various precommissioning stages of the product life-cycle. A suitable database architecture designed to support product data exchange and full life-cycle integration based on this product model is described and discussed.

During the last years a great range of computer aided tools has been generated to support the development process of various products. The goal of a continuous data flow, needed for high efficiency, requires powerful standards for the data exchange. At the FZG (Gear Research Centre) of the Technical University of Munich there was a need for a common gear data format for data exchange between gear calculation programs. The STEP standard ISO 10303 was developed for this type of purpose, but a suitable definition of gear data was still missing, even in the Application Protocol AP 214, developed for the design process in the automotive industry. The creation of a new STEP Application Protocol or the extension of existing protocol would be a very time consumpting normative process. So a new method was introduced by FZG. Some very general definitions of an Application Protocol (here AP 214) were used to determine rules for an exact specification of the required kind of data. In this case a product model for gear units was defined based on elements of the AP 214. Therefore no change of the Application Protocol is necessary. Meanwhile the product model for gear units has been published as a VDMA paper and successfully introduced for data exchange within the German gear industry associated with FVA (German Research Organisation for Gears and Transmissions). This method can also be adopted for other applications not yet sufficiently defined by STEP.

Labor in Indonesia is one of the ways for the community to be able to obtain an economy and is an abundant human resource. Practically, the definition of labor and labor is only differentiated by age limits. A financial institution is also a business entity whose main assets are in the form of money and cashable assets such as movable and immovable objects. One form of the financial institution itself is a bank. A bank is a business entity that specifically operates in the financial sector, which is obtained from the owner of the bank and then distributed to the public by providing savings and loans or what is commonly known as credit loans in that way the community can improve their economy and life expectancy. Regarding marriage, in companies, both government and private companies, stipulate a clause that limits the right to enter into marriage between workers working in the company. Termination of employment on the grounds that there is a marriage bond between workers, which has been approved or has been signed at the time of signing the contract agreement before starting to work in a company.

The European Commission initiated a discussion on the expediency of using the International Public Sector Accounting Standards (IPSAS), based on the IAS/IFRS, as a common base for harmonizing the public sector accounting systems of the member states. However, literature suggests that accounting is not neutral with respect to the economic, social and political dimensions. In the perspective of evolution of the accounting regulation outlined, balanced between accountability, with the need to represent phenomena for reporting pur-poses, and decisionmaking issues, which concentrates on the quantitative importance of the values, the paper aims to analyse the effects of the application of different criteria for the definition of the reporting entity of the local government consolidated financial statements (CFS). The Italian PCA 4/4, the test of control and the financial accountability approaches are examined. The evidence that emerged from the case studies examined identifies several criticalities in the Italian PCA 4/4 and support the thesis that the financial accountability approach is more effective in providing a complete representation of the public resources entrusted to and managed by the group, whereas the control approach better approximates quantification of the group results in terms of central government surveillance. The analysis highlights the importance of the post implementation review period and the opportunity to contextualize the adoption of the consolidated financial statement in the broader spectrum of the accounting harmonization process, participating in the process of definition of the European Public Sector Accounting Standards (EPSAS).

Drawing on Karin Bijsterveld’s triple definition of noise as ownership, political responsibility, and causal responsibility, this article traces how modern Japan problematized noise, and how noise represented both the aspirational discourse of Western civilization and the experiential nuisance accompanying rapid changes in living conditions in 1920s Japan. Primarily based on newspaper archives, the analysis will approach the problematic of noise as it was manifested in different ways in the public and private realms. In the public realm, the mid-1920s marked a turning point due to the reconstruction work after the Great Kantô Earthquake (1923) and the spread of the use of radios, phonographs, and loudspeakers. Within a few years, public opinion against noise had been formed by a coalition of journalists, police, the judiciary, engineers, academics, and municipal officials. This section will also address the legal regulation of noise and its failure; because public opinion was “owned” by middle-class (sub)urbanites, factory noises in downtown areas were hardly included in noise abatement discourse. Around 1930, the sounds of radios became a social problem, but the police and the courts hesitated to intervene in a “private” conflict, partly because they valued radio as a tool for encouraging nationalist mobilization and transmitting announcements from above. In sum, this article investigates the diverse contexts in which noise was perceived and interpreted as such, as noise became an integral part of modern life in early 20th-century Japan.
