Purpose: Purpose of this paper is the definition of a framework to describe the Technological Product Specifications (TPS) and the information associated with the geometric dimensioning and tolerancing to integrate the design concepts into a commercial inspection system. Design/methodology/approach: A functional tolerance model provides a complete framework to define the geometric dimensioning and tolerancing and its relationship with the part geometry and the inspection process. This framework establishes a connection between a computer aided design and computer aided inspection system throughout the exportation of the information associated to the dimensions and tolerance of the part into a commercial CAI system. Findings: They are mainly focused on the definition of a framework that describes the relationship between the entities of dimensions and tolerances with the geometry of the part. The information imported to a CAI system allows to develop the inspection process without the additional information provided by a physical drawing of the part. Research limitations/implications: They regard the limited access to commercial CAI system and to the lack of protocols of exchange of data associated to the tolerances of the part. Practical implications: They involve facilitation of the inspection process development. This implication allows realizing the inspection process reducing the time spent to define the geometry to inspect and the parameters that must be controlled. Originality/value: The main value of this research is the development of a unique framework to extract the information related to the geometric dimensioning and tolerances and the geometry of the part in a common model. This model provides a complete definition and representation of the entities, attributes and relationship of design and inspection system.

Purpose: Purpose of this paper is present a detailed framework to integrate the Computer Aided Design (CAD) and Inspection (CAI) systems through the integration of the Geometric Dimensioning and Tolerancing (GD&T) with the inspection process in coordinate measuring machines (CMMs). Design/methodology/approach: The approach used to develop a prototype of a Knowledge Based System (KBS) applied to inspection process establishes a new methodology for integrate the geometric dimensioning and tolerancing (GD&T). The integration is achieved through the definition of the knowledge units for functional properties of GD&T, inspection resources and inspection operations in a common knowledge model. The manufacturing and processing applications are the main topics approach of this paper. Findings: The findings are focused in modeling the features and interactions between knowledge units associated to topology, geometry and tolerances with the inspection process activities. The implementation of the product knowledge model is presented in a computer platform that extracts and represents the GD&T information in a CAI system. Research limitations/implications: The implications are focused on the automation of the inspection process in a KBS application. The future research is focused on the use of artificial intelligent technique, such as genetic algorithms and neural networks, to optimize the time to execute the inspection process. Practical implications: The main outcomes and implication of the KBS prototype application are focused on the reduction of the time spend to develop the inspection process. This KBS application provides the needed information to elaborate this process without the human interface. Originality/value: The original value of this paper is the integration of the design and inspection specification in a unique prototype application. The knowledge model has been defined in a common modeling language (UML) and can be implemented in different informatics platforms.

Artykuł dotyczy sporu o powszechną lustrację dziennikarzy, która miała być wprowadzona na podstawie rozwiązań prawnych z okresu tzw. IV Rzeczpospolitej, projektu politycznego realizowanego w Polsce w latach 2005–2007. W tekście skoncentrowano się na sporze środowiska dziennikarskiego o lustrację dziennikarzy regulowaną ustawą, która weszła w życie w 2007 r. Ostatecznie przepis o lustracji dziennikarzy został uznany przez Trybunał Konstytucyjny za niezgodny z konstytucją. Artykuł jest częścią projektu badawczego dotyczącego relacji IV Rzeczpospolitej z mediami w latach 2005–2007. Autor bada różne aspekty tych relacji. Są to zarówno badania prasoznawcze wybranych tytułów prasowych w odniesieniu do konkretnych wydarzeń politycznych z lat 2005– 2007, jak i analizy problemowe dotyczące niektórych aspektów związanych z funkcjonowaniem mediów. Przeprowadzenie i poszerzenie zakresu lustracji było jednym z postulatów pr ogramowych IV Rzeczpospolitej, miało służyć oczyszczeniu państwa z naleciałości PRL. Propozycja powszechnej lustracji dziennikar zy wywołała jednak ostry spór w środowisku dziennikarskim w Polsce. Przeciwnicy zapisów lustracyjnych argumentowali, że mogą one godzić w konstytucyjne zapisy dotyczące wolności słowa. Podnoszono także, że to sami dziennikarze, a nie władze państwowe mają dbać o wiarygodność zawodu dziennikarskiego. Kilku znanych dziennikarzy zapowiedziało, że mimo zapisów ustawowych nie podda się lustracji. W środowisku dziennikarskim byli jednak krytycy takiej postawy. Uważali oni, że podstawą pracy dziennikarza jest wiarygodność, która daje mandat do występowania w imieniu opinii publicznej. Ich zdaniem bojkot składania oświadczeń lustracyjnych wystawiał na szwank wiarygodność dziennikarską.

The article touches upon disputes about obligatory Lustration of journalists. Those restrictions was planned to be imposed under legislation from the political project (2005- 2007) during the IV Republic of Poland. The article focuses on the dispute within the journalistic environment connected with Lustration, which came into force in 2007. Ultimately, this obligation was recognized by Constitutional Tribunal as illegal. The article is a part of a research project connected with relations between the IV Republic of Poland and the media in the years 2005–2007. It consists of the research into different newspaper titles connected with political events from 2005–2007 as well as articles connected with chosen aspects of the functioning of the media system in Poland. Implementing and broadening the scope of Lustration was one of the postulates of the program of the IV Republic of Poland, which was intended to purge the state of the remnants of the People's Republic of Poland. However, the proposal of general lustration of journalists caused a sharp dispute among the journalists in Poland. Opponents of the provisions of Lustration argued that they could breech constitutional provisions regarding freedom of speech. It was also argued that it was the journalists themselves, and not the state authorities, who ought to take care of the credibility of the journalist profession. That is why several well-known journalists announced that, despite the statutory provisions, they would not submit to Lustration. In the journalistic milieu, however, there were critics of this attitude. They believed that the basis of a journalist's work is credibility, which provides a basis for acting on behalf of the public. In their opinion, a boycott of Lustration jeopardized journalistic credibility.
