Integrating Six Sigma into a Quality Management System in the Medical Device Industry
No full textSix Sigma is a valuable management strategy to improve business processes, reduce development and production costs, increase profit margin and improve customer satisfaction. The purpose of this paper is to describe how applicable Six Sigma concepts may complement and support formal quality management systems (QMS) in the medical device industry.A significant number of issues, which increase the development costs and times, is often found during different phases of a medical device life cycle. Some defects with high patient safety risk may result in dangerous and very costly product recalls.The basic idea of this paper is to explore the possibilities of integrating Six Sigma techniques with an existing QMS throughout the entire life cycle of a medical device. This paper addresses how Six Sigma techniques, when appropriately integrated into the QMS at medical device companies, can eliminate defects earlier in the medical device life cycle, identify major opportunities for cost savings, focus on customer needs and expectations, and improve the overall business processes
Suitability of Modern Software Development Methodologies for Model Driven Development
No full textAs an answer to today’s growing challenges in software industry, wide spectrum of new approaches of software development has occurred. One prominent direction is currently most promising software development paradigm called Model Driven Development (MDD). Despite a lot of skepticism and problems, MDD paradigm is being used and improved to accomplish many inherent potential benefits. In the methodological approach of software development it is necessary to use some kind of development process. Modern methodologies can be classified into two main categories: formal or heavyweight and agile or lightweight. But when it is a question about MDD and development process for MDD, currently known methodologies are very poor or better said they don't have any explanation of MDD process. As the result of research, in this paper, author examines the possibilities of using existing modern software methodologies in context of MDD paradigm
Interactions Validation Methods for Training Resources Control Engine Development
No full textThe training courseware complexity proper selection is one of the most difficult factors looking from an intelligent application engine development. The application needs individual settings, the most relevant for the application structure matching to the users' individual expectations. What is more, the obtained structure allows controlling dynamically the application within a time it is used. The application units description with their controlling functions allow joining the database components into individual composition of the courseware. The paper in-troduces several aspects of distance learning resources development, fulfilling the demanding assumptions of the interactive training units
Double Separation Method for Translation of the Infrared Information into a Visible Area
No full textInformation visualization refers to the wavelength area ranging from 400 to 700 nm. Areas in lower wavelengths ranging from 100 to 400 nm are translated into the visual area with the goal to protect information visible only by applying instruments adapted for the ultraviolet area. Our recent research work refers to the infrared wavelength areas above the visible specter up to 1000 nm. The scientific contribution of this paper is in setting the double separation method for printing with CMYK printing inks with the goal to detect graphic information in the infrared area only. An algorithm has been created for making visual basics in the overall visible specter containing material that responds in the infrared section. This allows planning of areas in all coloring types for one and the same document that contains a secure piece of information. The system is based on double transition transformation of the visible RGB1 information recognition into CMYK2 in the same document. Secure information is recognized with the help of instruments in the set wavelength range. Most of the experiments have been carried out by analyzing the same set of RGB records. Each sample in the set was a test unit coming from another source containing different IR3 components. Thus an innovative method of color mixing has been set where colors appear respectively in daylight and separately according to IR light programming. New IR cryptography is proposed as shown in the experimental work
Linguistic competence in tertiary-level instruction in English and its relevance for student mobility
No full textStudent and teacher mobility are important aspects of education within the Bologna Process. Overcoming the language barrier is a precondition for following and providing instruction in a foreign language. A survey was conducted among first-year undergraduate students to determine their readiness for instruction in English. The survey results show the respondent profile, their assessment of instruction within an English language course, using other ways of acquiring knowledge and self-assessment of their command of English. The students' self-assessment of motivation for learning English and its relevance for their profession are presented along with students' interest in other courses offered in English. It turns out that, regardless of a satisfactory level of self-assesed competence in English and motivation for learning English, students are not willing to enroll in the offered study courses in English. This may indicate that all the precoditions for mobility have not been fulfilled. The survey results are compared with the corresponding results of another, more comprehensive, survey among graduate students at the Faculty of Organization and Informatics conducted at the whole University of Zagreb. Althouh the results obtained in the two surveys are not identical, they roughly correspond
An Uncontrolled Item of Enterprise ICT Innovation: the High Level Digital Divide
No full textThe globalization phenomena strongly stresses western countries’ economies. Especially in industrial districts, companies are reacting with continuous innovations in product and process, based mainly on the introduction of ICT. This continuous organizational change process forces employees to keep in touch with the working environment in an endless learning process. Therefore, the introduction of new ICT seems to bring a cultural development for individuals. Is this always true? Our conviction is that the strong ICT impact generates a new form of digital-divide, a “High-Level Digital Divide” (HLDD): an increasing cultural distance between people able to follow the enterprise ICT evolution and complexity, and people with a lower cultural growth ability. An uncontrolled growth of HLDD may limit the evolution capacity of the enterprise and drop out people from labor market

A Heuristic Approach to Possibilistic Clustering for Fuzzy Data
No full textThe paper deals with the problem of the fuzzy data clustering. In other words, objects attributes can be represented by fuzzy numbers or fuzzy intervals. A direct algorithm of possibilistic clustering is the basis of an approach to the fuzzy data clustering. The paper provides the basic ideas of the method of clustering and a plan of the direct possibilistic clustering algorithm. Definitions of fuzzy intervals and fuzzy numbers are presented and distances for fuzzy numbers are considered. A concept of a vector of fuzzy numbers is introduced and the fuzzy data preprocessing methodology for constructing of a fuzzy tolerance matrix is described. A numerical example is given and results of application of the direct possibilistic clustering algorithm to a set of vectors of triangular fuzzy numbers are considered in the example. Some preliminary conclusions are stated
An Investigation of Marketing via Mobile Devices - Attitudes of Croatian Marketing Experts
No full textMarketing activities supported by mobile devices offer great opportunities for direct communication with consumers without the barriers of time, place, location and other. This article explores opinions and expectations Croatian marketing experts have towards use of m-advertising and other available advertising media, where we take the perspective of marketing experts to predict the future of m-marketing and m-advertising in Croatia. The paper also discusses the relevance of m-advertising and investigates the future of m-marketing and m-advertising in Croatia.
This research focuses mainly on understanding the potential and effectiveness of the use of mobile phones as a promotional medium, but we also try to recognize the level of concern of marketing experts associated with spam, relating to privacy intrusion and ethics components in m-advertising. Privacy and ethics concerns could create resistance to the adoption of m-advertising.
Media selection becomes the most critical factor for the success of a promotional and advertising marketing campaign. Croatian experts still consider TV or newspapers the best way to reach a large number of potential consumers, but what are their expectations towards mobile advertising? To answer this question, we built a model that links attitudes towards advertising via classical media to the intention to use m-advertising
