Linking sustainability reporting and energy use through global reporting initiative standards and sustainable development goals

Árpád Tóth Alex Suta Péter Molnár Bence Lukács

Publication Name: Clean Technologies and Environmental Policy

Publication Date: 2025-12-01

Volume: 27

Issue: 12

Page Range: 8659-8667

Description:

This paper addresses the critical need for an integrated approach to sustainability reporting by examining the transition from internal combustion engine vehicles to electric vehicles within the automotive industry. By focusing on the top 8 highest-revenue global automakers in 2022, the study utilizes the Global Reporting Initiative (GRI) standards and United Nations Sustainable Development Goals to assess contributions to SDG 7 (affordable and clean energy) and other pertinent indicators. A comprehensive content analysis and logistic regression analysis are employed to explore the correlation between energy use and compliance with GRI standards from 2018 to 2022. The findings reveal significant trends in sustainability reporting, with a noted decrease in quality in the final year analyzed. Specifically, GRI 302-3 (energy intensity) shows a significant negative relationship with energy consumption, indicating higher energy usage correlates with lower compliance. The study reinforces the necessity for more transparent and effective sustainability reporting frameworks to enhance corporate practices and drive progress toward sustainability goals.

The role of purpose in life as reflected in the indicators of body composition, fitness and quality of life in women working in the social sector

József Bognár Csaba András Dézsi Zsolt Szakály Zoltán Tánczos

Publication Name: Orvosi Hetilap

Publication Date: 2021-07-01

Volume: 62

Issue: 27

Page Range: 1089-1098

Description:

Introduction: Professionals working in the social sector typically do significant overwork in rather unfavourable working conditions. Although the purpose in life is proved to determine the areas of career, health awareness, and the quality of life, the latter has not yet been confirmed among social workers. Objective: The purpose of this research is to demonstrate body composition and fitness status as well as the quality of life of female employees (n = 127) at a social institution, furthermore the decisive role purpose of life plays in these indicators. Method: Data were collected through questionnaires, tests, body composition analyses, and fitness status tests, and were assessed by t-test, analysis of variance and regression analysis. Results: Body composition of the participants indicates a generally overweight status, while fitness status, quality of life, and purpose of life are within the acceptable range, however, all with notable range values. Those with a higher-level purpose of life demonstrate better fitness indicators and higher quality of life. In terms of body composition, fitness, and quality of life, only a minor difference was found between those who do intellectual and physical type of work. Those who took sick leave demonstrated a lower level of fitness and quality of life compared to those who did not take any sick leave. Body composition and fitness status have proven to deteriorate with age. Conclusion: Previous research findings can be confirmed by stating that neither the body composition and fitness indicators, nor the quality-of-life level of social workers are optimal. The determining role of purpose in life has been proven in substantial aspects in this study. One of the focus areas of enhancing purpose in life is the workplace, where major positive impacts can be achieved in terms of the physical and mental health, well-being, and work performance.

Dem modeling of crushable grain material under different loading conditions

Majid Movahedi Rad M. Amine Benmebarek

Publication Name: Periodica Polytechnica Civil Engineering

Publication Date: 2021-07-13

Volume: 65

Issue: 3

Page Range: 935-945

Description:

This paper deals with the effect of contact conditions on the crushing mechanisms and the strength of granular materials. The computation of crushable grain material under different loading conditions is performed using 3D model of discrete element method (DEM). The crushable macro-grain is generated from a large number of identical spherical micro-grains which are connected according to the bonded particle model. First, the parameters of the proposed DEM model are calibrated to match the force-displacement curve obtained from Brazilian Tests performed on cylinders made of artificially crushable material. The damage profile right at the point when the force-displacement curve reaches its maximum is seen to replicate the same crack patterns observed in Brazilian test experiments. Then, parametric investigations are performed by varying the coordination number, the contact location distribution, and the contact area. The results show that these parameters play a significant role in determining the critical contact force and fracture mechanism of crushable particles compared to a traditional macro-grain crushing test. Increasing distribution and coordination number of the macro-grain increases particle strength when large area contact is permitted. However, for linear contact area, the effect of increasing coordination number on particle strength is marginal.

Cost-efficient localisation system for agricultural use cases

Sébastien Aubin Olivier Camp Gábor Paller Gábor Élo

Publication Name: Sensornets 2017 Proceedings of the 6th International Conference on Sensor Networks

Publication Date: 2017-01-01

Volume: 2017-January

Issue: Unknown

Page Range: 142-149

Description:

Connected agricultural applications often depend on exact localisation solutions. Often the term “precision agriculture” implies a technology that identifies the location of the livestock, crop, field of agricultural machinery with more or less of precision. While precision requirements vary, the localisation often has to be quite precise like sub-meter or even decimeter precision. Dual-band GPS solutions are able to satisfy these high-precision requirements but these equipments are quite costly and their purchase is often regulated. This paper presents two agricultural use cases and the combination of low-cost GPS and short-range localisation systems that are able to satisfy high-precision requirements for fraction of the costs of dual-band GPS.

Selection of Engine Oils with Tribological Examinations Applicable to Specially Operated Diesel Engines

L. Földi Rajmund Kuti D. Tóth L. Csapó F. Könczöl Cs Papp

Publication Name: Fme Transactions

Publication Date: 2024-01-01

Volume: 52

Issue: 2

Page Range: 335-342

Description:

In recent times, many specially engineered diesel engines built in the 1980s are still used in different areas, for which the suggested engine oils are no longer available. These engines are operated reliably in military combat vehicles, electricity generators, and tracked machinery, thus it is essential to examine what engine oils are suitable for their operating conditions and may be used as their engine oil. The aim of our research is to conduct the tribological examination of an oil sample taken from a V-6M type naturally aspirated Diesel engine and the oil prescribed by the manufacturer. After evaluating the results, we determine which type of oil is applicable in the engine to achieve safe operation and a long lifetime.

Reviving an unpopular tourism destination through the placemaking approach: Case study of Ngawen temple, Indonesia

Laszlo Vasa Lóránt Dávid Setiawan Priatmoko Moaaz Kabil Edit Ilona Pallás

Publication Name: Sustainability Switzerland

Publication Date: 2021-06-02

Volume: 13

Issue: 12

Page Range: Unknown

Description:

Changes in tourists’ behavior in recent times have been considered a driving force for emphasizing the importance of unpopular tourism destinations as one of the key potentials in the tourism industry in any nation. On the road to reviving unpopular tourism destinations, this study aims to identify the potential tourism aspect and development of the Ngawen Temple in Indonesia. This research applies the placemaking approach as the main strategy for resurrecting Ngawen Temple. By using visitor surveys, visitor flows, and community surveys, this research obtains a clearer assessment for determining the planning development of Ngawen Temple. The research results revealed that unpopular destinations still have the potential to be developed and bring more benefits to the local economy by conducting a comprehensive placemaking approach. Accordingly, possible strategies based on various literature and field observations can provide clues to stakeholders on how to use their tourism assets to improve local communities’ economies. Some of the most frequently proposed strategies are the following: link the unpopular destination with other popular ones through structured tourism trips; design a “tourist trap,” which is a created place to hold tourists longer in a destination using new additional facilities; improve the infrastructure; and establish more creative tourism spaces, such as tourism centers.

Publication Name: 7th IEEE International Conference on Cognitive Infocommunications Coginfocom 2016 Proceedings

Publication Date: 2017-01-03

Volume: Unknown

Issue: Unknown

Page Range: 469-484

Description:

In the paper we intend to show in detail how the issue of the transition from the 'Pisces' into the so-called 'Aquarius' 'World age' moves through the world view of the two major minds', Wolfgang Pauli and Carl G. Jung's world view of special scientific interpreting 'Psyche and Nature' through the reinterpreted symbols of astrology in a 'synchronistic way' in particular from the point of view of their last years 'cooperation' of not entirely conflict-free. As far as is possible, we touch the issues of their early dreams and symbolic interpretations related to the zodiac and age of the Aquarius.

Publication Name: 2016 IEEE Symposium Series on Computational Intelligence Ssci 2016

Publication Date: 2017-02-09

Volume: Unknown

Issue: Unknown

Page Range: Unknown

Description:

In this study we will describe an intervention decision-support method related to residential buildings, which is modelling the condition of buildings based on linguistic expert opinions so that it is capable of taking into consideration the uncertainties included in the expert opinions. Fuzzy signature-based model is used, wherein the uncertainties are integrated into the system by applying interval valued fuzzy sets, as well as linguistic hedges. The result will be a fuzzy set for each building, describing the condition of the whole building, specify the bourdary values between which the condition of the building may fall.
