Description:

Sustainability measurement has become one of the most important topics for automotive manufacturers. The financial reporting practice has been faced with an increased digitization and standardization process, which was enabled by the either voluntary or required implementation of the eXtensible Business Reporting Language (XBRL) platform. The obligatory adaption appeared in European legislation, which covers both financial, and non-financial information. In the current study, we have made a comparison of the most significant European and American automakers' sustainability reports data content to utilize the sustainability XBRL taxonomy adaptation. Using literature, the development of disclosure requirements was reviewed, following which the adaptation to global sustainability standards (GRI, SASB) in reporting was examined from a qualitative point of view, using a text mining methodology. It has been concluded that by the biggest automotive manufacturers the conditions are currently met to a limited extent, but the most significant obstacle is the lack of linking sustainability information to financial impacts. If the financial regulations require OEMs to adapt, and potentially disclose negative information (such as pollution data, penalties) may negatively affect investor perception. Based on the review XBRL is capable to become a global standard, however, reported contents should be carefully audited and linked to objectively verifiable financial data to provide relevant information to investors, decision-makers.

Volume: 2005

Issue: Unknown

Page Range: 229-232

Description:

With the recognition that the engineering structures maintenance and repair needs far exceed the rescourses available to adress these needs, many firms have to turned to the development of ESMS (Enginnering Structures Management System) as a method to improve the allocation of these limited resources and the condition of their engineering structures. The ESMS is based on performance modelingbecause of without the actual condition of the structures and the future deterioration process any model could not be build up. The paper provides an overviev of the need for ESMS and the posibble description of the performance modeling. © 2005 IEEE.

Cooperation between the health visitor and the physician as one of the pillars of the 108-year-old Hungarian Health Visitor Service

Petra Szabó-Németh Krisztina Horváth Zsuzsanna Soósné Kiss

Publication Name: Orvosi Hetilap

Publication Date: 2023-08-20

Volume: 164

Issue: 33

Page Range: 1311-1318

Description:

Introduction: Despite the more than 100-year history of the Hungarian Health Visitor Service, no study has yet been carried out that looked back at the cooperation between health visitors and physicians. Objective: Our aim was 1) to explore the professional advances of the health visitor service and the cooperation between health visitor and physician by examining historical documents, legal and professional regulations governing the work of health visitor, furthermore, 2) to investigate whether there are compulsory training elements in today's training for health visitors that prepare students for health visitor and physician collaboration, moreover, 3) to search for old tools and documents used by health visitors and doctors in the North-West of Transdanubia. Method: A literature search was carried out to identify documents relating to the development of the work of health visitors, the cooperation between health visitors and physicians, past and current legal and professional regulations, the current regulation on training of health visitors. Through field research, we tracked down old tools and documents of health visitors and physicians. Results: The establishment of the Hungarian Health Visitor Service is associated with the names of professors of medicine. The historical documents and regulations testify the development of the work of the health visitor, the expansion of her competences and the importance of the health visitor and physician cooperation. The training competences required for the cooperation between health visitors and physicians, health visitors and specialists are regulated by the regulation on training of health visitors. We have found many old objects and documents used in the work of the health visitor and doctor. Discussion: The documents that have preserved almost invariably describe the health visitor as a person working alongside the physician, in cooperation with the physician. Nowadays, the regulation of cooperation covers for all specialties in the field of health visitor. Conclusion: Based on our research, it is fair to say that the health visitor-physician cooperation is an important pillar of the 108-year-old Hungarian Health Visitor Service.

Publication Name: 6th IEEE Conference on Cognitive Infocommunications Coginfocom 2015 Proceedings

Publication Date: 2016-01-25

Volume: Unknown

Issue: Unknown

Page Range: 229-233

Description:

This paper aims to explore and identify the trends and main streams of digitalization and cognitive info-communications in the field of communication management in Europe. The analysis based upon the database of European Communication Monitor (ECM)1 2007-2015 which is the largest study on strategic communication worldwide. The paper focuses on the development of communication channels, online communication and social media, furthermore tends to give an overall picture about the rapidly growing role of social media as a tool among European communication practitioners. This electronic document is a "live" template and already defines the components of your paper [title, text, heads, etc.] in its style sheet. In the frame of our paper we give an overview about the trends and long term features - such as digitalization, info-communication, and social media - on communication management. What we can follow as clear trends during the 2007-2015 periods are as bellow: • development of communication channels/instruments; • coping with the digital evolution and the social web become the most important (strategic) issues for • communication management; • overall trend the interactive communication and online communities, and • emerging interactive channels: social media, networks and online videos. There are phenomena which appear in a particular year and become a constant element of the tools by today, and there are new elements in every year. The importance of printed media is radically reduced, and replaced by online media. With their help will be the stakeholders, the media and the pubic available. Next to the online communication and online media, the forging ahead of social media (social networks, blogs, etc.) is the most important source of changes. The importance of to be present in social media is gradually becoming more and more obvious to companies. Social media means a real dialogue, and it requires substantial resources. As the World Wide Web becomes more and more influential, the global media become the most important tools of the global communication management on reaching the public.

Optimizing Computer Engineering Problems Using CODAS Method with Bipolar Complex Fuzzy Soft Frank Aggregation Operators

Tahir Mahmood Abdul Jaleel Muhammad Iftikhar Dragan Pamucr

Publication Name: Contemporary Mathematics Singapore

Publication Date: 2025-01-01

Volume: 6

Issue: 4

Page Range: 5145-5171

Description:

In this article, we start by explaining why Bipolar Complex Fuzzy Soft Set (BCFSS) is better than existing approaches by highlighting its abilities to enhance Computer Engineering (CpE) by removing ambiguity more effectively than Fuzzy Set (FS), Fuzzy Soft Set (FSS), Complex Fuzzy Soft Set (CFSS), Bipolar Fuzzy Set (BFS), Bipolar Fuzzy Soft Set (BFSS), and Bipolar Complex Fuzzy Set (BCFS). This will improve effectiveness as well as clarity. Make sure that those new to fuzzy sets properly understand the key issue in CpE. Reveal first the BCFSS’s new strategy and then detail how it differs from existing approaches, pointing out the overlooked features of previous approaches that justified your research. Enhance the preparation concept link by explaining how BCFSS enhances CpE Decision-Making (DM) in situations when conventional models are inadequate when paired with Frank Aggregation Operator (AO) (Frank Arithmetic Aggregation Operator (FAAO) and Frank Geometric Aggregation Operator (FGAO)). Moreover, keeping in mind the effectiveness of the “Combinative Distance-based Assessment (CODAS) method” we developed this method in the framework of BCFSSs and used this method and develop AOs to solve some decision-making problems related to CpE. Our sentence structure should also be refined to provide smooth transitions between ideas and to enhance readability and navigation. Lastly, provide comparison studies that highlight the improvement’s superiority over current methods to show that it is feasible.

Investigation of frequency dependent mechanical properties of porous materials using dynamic mechanical analyzer and frequency-temperature superposition theory

Balázs Vehovszky Attila Schweighardt

Publication Name: Proceedings of Inter Noise 2021 2021 International Congress and Exposition of Noise Control Engineering

Publication Date: 2021-01-01

Description:

In acoustic design of engineering applications - such as in the acoustic analysis of passenger vehicles - poroelastic materials are of great importance. One of the most influencing properties in determining their noise-reduction potential is the storage modulus. The purpose of this study is to examine the frequency dependence of storage modulus of selected porous acoustic materials at least up to 1000 Hz. This is executed by using the combined use of dynamic mechanical analyzer and frequency-temperature superposition theory. All other methods for measuring the storage modulus fall short in determining frequency-dependence above 100 Hz: quasi-static mechanical analyzer is mostly used for determining an averaged constant value deduced from low-frequency measurements, while the usage of an electromagnetic shaker capable for high-frequency excitation may include effects of fluid motion inside the pores, thus significantly modifying the results. Frequency-temperature superposition enables to determine the storage modulus values in a wide frequency range, based on low-frequency measurements, where fluid-structure interaction is negligible. It was found that the modulus varied significantly up to and beyond 1000 Hz, and thus, acoustical characterization of these materials can be significantly improved using the proposed method. The work concludes with recommendations to improve the accuracy of the results.

The business behaviour of representatives of small-and medium-sized enterprises in cross-cultural interaction situations

Júlia Szőke

Publication Name: Tarsadalomkutatas

Publication Date: 2014-01-01

Volume: 32

Issue: 2

Page Range: 162-175

Description:

In the present paper based on the database of our own research from 2012 we examine with the help of some dimensions of national culture how the business behaviour of representatives of small-and medium-sized enterprises (henceforth SMEs) can be characterised in cross-cultural interaction situations. Previous pieces of research (e.g. Hofstede 1980, Bartlett-Ghoshal 1990) have already verifi ed that the norms, habits and behaviour patterns learnt as part of national culture strongly influence the behaviour of the members of the society therefore the business behaviour of employees as well, however, according to our hypothesis the business behaviour of representatives of SMEs is not unifi ed in cross-cultural interaction situations but can be subdivided into different categories. One novelty of our paper is that our research was concentrated on a geographical area since the sample included only representatives of Hungarian SMEs from the three counties of West-Transdanubian region with the condition that they participate in cross-cultural business relations with Austrian partner. The other novelty of the research is that the business behaviour of the respondent representatives was analysed by using some national culture dimensions of three researchers (Hofstede 1980, Trompenaars 1995, Hall 1975 and 1990), but based on the fi ndings the culture dimensions of a fourth researcher, Gesteland (2005) were outlined from the data. In our paper we fi rst introduce the theoretical background of the research, then we draw up its methodology, and fi nally as a result of our research we present the business behaviour of the representatives of SMEs from the examined region in cross-cultural interaction situations and its characteristics.

Description:

ENUM is the short name for a protocol for connecting resources of telecommunication and the Internet to one another. It specifies a rule that makes it possible to relate a domain to a telephone number without any risk of ambiguity. This domain can then be used to identify various communication services like fax, mobile radio, voice-mail systems, e-mail addresses, IP telephony addresses, web pages, GPS coordinates, call diverts or unified messaging. Several countries in the world examine the possibilities of the use of ENUM in national trials. Recently two Hungarian universities and an Internet service provider established a research project aiming the development of ENUM based communication services. In Hungary we have to deal not only with the questions of creating and providing the technological background, but also with the business aspects of ENUM based service development. The article will firstly give an overview about the ENUM itself. Then it will deal with ENUM services and business models. After that we discuss the situation of ENUM in different European countries. It will present the planned and accomplished ENUM based services in these countries. Then we are going to give the aims of the project in Hungary, which is led by the Szechenyi Istvan University in Gy6r. In setting these aims we can rely on the projects of other countries, and learn from them. © 2005 IEEE.
