Abstract: In all welded assemblies, the joining area must meet the mechanical and functional requirements imposed on the assembly. High importance is placed on the hardness profile across the weld cross-section to determine the mechanical properties of the welded assembly. This study highlights the variation in hardness measured along the cross-section of a welded area in TIG- and MIG-welded AlSi7 joints. The results reveal aspects of grain orientation and suggest that the material may crack outside the weld zone.

Tzvetelin Gueorguiev. Added Value of Certification and Accreditation of Educational Quality Management Systems.

Добавена стойност на сертификацията и акредитацията на системи за управление на качеството в образованието

International Scientific Conference UNITECH, Gabrovo, 2025, “UNITECH – SELECTED PAPERS”, vol. 2025, pp. 1-5. Published by Technical University of Gabrovo, ISSN 2603-378X .

Abstract: The paper presents a critical review of educational quality management systems and their implementation in Bulgarian higher education institutions. The accreditation of universities is implemented and supervised by the National Evaluation and Accreditation Agency (NEAA). Certification of quality management systems in universities is voluntary, and maintaining ISO 9001 certified status is a process that requires additional efforts and funding. Thus, what motivates universities to pursue and maintain such certifications is the perceived added value of the improved quality management system. Another ISO standard attracts the attention of quality managers in educational organizations - ISO 21001. Whether this standard will disrupt the existing quality management systems is debatable, but it is definitely an opportunity that needs further exploration.

Keywords: educational organization, university, quality management system, certification, accreditation, ISO 9001, ISO 21001.

Abstract: The purpose of this study was to investigate the effect of a professional development workshop conducted on a technology-enhanced climate change curriculum that aimed to foster faculty members’ technological pedagogical content knowledge (TPACK) and their cognitive structures. For this purpose, a total of 24 faculty members, from Türkiye, Bulgaria, Lithuania, and Latvia were trained at a three-day faculty training event in Latvia. The analysis revealed a statistically significant difference between the two sets of scores (W=15021.0, 𝑝𝑝<0.001), suggesting that the intervention had a measurable impact on participants' self-efficacy. The word association test results indicated increased complexity of cognitive structures, indicating that the participants mentioned subdimensions of climate change, such as carbon footprint, biodiversity loss, deforestation, renewable energy and environmental responsibility after the workshop. Overall, the results indicated that the workshop had a positive impact on the faculty members’ TPACK self-efficacy perceptions as well as their cognitive structures. Implications include providing explicit training on the subdimensions of climate change education, creating connections between climate change and character and values, and increasing technological pedagogical content knowledge.  

Keywords: Character and values, climate change education curriculum, cognitive structures, faculty members, TPACK self-efficacy perception.

Abstract: The current edition of the United Nations Sustainable Development Goals (UN SDGs) focuses on global sustainable development efforts and covers the period from 2016 to 2030. Since 2019 the International Organization for Standardization (ISO) has been aligning its standards to the 17 UN SDGs. In December 2023 ISO published the first edition of the international standard on Artificial Intelligence Management Systems (AI MS). The technical progress known as Industry 4.0 and the emerging Industry 5.0 trends make AI a valuable asset to any organization’s management system. This recent development brings along not only desirable benefits and opportunities to integrate AI in the planning, implementation, control and improvement of operations. It also introduces uncertainty and risks to the processes of the MS. To address those risks and opportunities, and to manage the innovation processes organizations can use the guidelines for contributing to the UN SDGs. They are published in September 2024 by ISO as the Publicly Available Specification ISO/UNDP PAS 53002:2024.

The purpose of this paper is to provide a roadmap for organizations of any size and industry sector on how to integrate AI and UN SDGs in the processes of their management systems.

(Volume 38, Supplement, May 2025, 101787)

Abstract: The current state of ISO 9001-based quality management systems is intertwined with the updates of Annex SL, the United Nations' Sustainable Development Goals (UN SDGs), and more recently – the effect of climate action changes. In December 2023, ISO published the standard ISO/IEC 42001:2023 “Information Technology — Artificial Intelligence — Management System”. This presents itself as an actionable opportunity for organizations around the world to enhance their existing management systems. The drive for innovations and the risk appetite of organizations shall be balanced by the ethical and responsible use of AI to build trust in AI applications. This paper presents a comparative analysis and suggests an approach to integrate the best practices established in the proven ISO 9001 standard with the brand-new AI management system standard. The threat of being hampered by the potential societal challenges provoked by late and insufficient AI integration in their management systems is very real. To stay afloat and, more importantly, to prosper organizations need to act and adapt to these impactful game-changing trends.

Materials Research Proceedings, Vol. 46, pp 129-134, 2024. DOI: https://doi.org/10.21741/9781644903377-17.

Abstract: Among all the cutting processes, the turning process is the most widely spread process currently used in industry. Together with the machine tool, using the movements performed during work piece machining, the process could be adapted to achieve other processes techniques. An example of innovation has been proposed in this study. The authors emphasize a new perspective of using a lathe machine tool by its cutting tool, which after being used in the turning process can be used as a tool for performing a plastic deformation process. This fact will contribute to an increase in the hardness of the processed surface. The device obtained by using the ideas diagram method will enable its use to perform cold plastic deformation with the same cutting tool used in the turning process. The results, materialized by the obtained device, will allow the performance of all necessary movements to ensure the conditions that allow the implementation of the process and to obtain an increase of the surface hardness for a cylindrical work piece initially subjected to a turning process.

Keywords: Turning Process, Cold Plastic Deformation, Ideas Diagram Method, C-K Method.

UniTech Selected Papers, pp. 1-6, ISSN: 2603-378X, 2024. http://www.doi.org/10.70456/UIFI9691 

Abstract: The Plan-Do-Check-Act (PDCA) cycle is a keystone feature of the structure of any ISO management system standard (MSS). The most popular MSS - ISO 9001:2015 with requirements for a quality management system focuses on the PDCA cycle in its section devoted to the process approach which is also one of the seven quality management principles. In September 2024, ISO published the first edition of ISO 56001 - the standard with requirements for an innovation management system. The structure of ISO 56001 from Clause 6 to Clause 10 is aligned with the steps of the PDCA cycle at the system level. Surprisingly, Clauses 4 and 5 which contain requirements for the innovation management system and leadership are not explicitly mentioned. The purpose of this paper is to present a method for analyzing and uncovering the steps of the PDCA cycle at the clause/process level, and further on – at the activity level. The work preceding the drafting of this paper involved an in-depth analysis of the core text of ISO 56001:2024 and using previous research on ISO 56002:2019 as a guide to determine the steps of the PDCA cycle. The results will facilitate managers in enhancing their integrated management systems with elements of innovation management.

Keywords: PDCA Cycle, Innovation Management Systems, ISO 56001, ISO 56002.

Abstract: Management systems help organizations achieve their strategic direction, and enhance the effectiveness and efficiency of their processes. The ISO management system standards are based on a pivotal principle - the process approach. The first edition of ISO 42001 - the standard for Artificial Intelligence (AI) Management Systems (MS) was published in December 2023. This is a good opportunity for organizations to keep up to date with the modern context and integrate AI into their MS. This paper presents a model that helps to establish the input clauses and output clauses of individual ISO 42001 processes, better understand the interactions between the processes, and create an overall view and representation of the AI MS based on these processes.

Keywords: artificial intelligence, management systems, process approach, ISO 42001:2023, standard.

Abstract: In recent years, the gap between perceptions and knowledge transfer widens significantly. This trend is especially pronounced as Generation Z representatives are becoming more influential at the organizational level. The undisputedly most popular management systems standards are based on the ISO 9000 series for quality management systems. The turn of the century has witnessed the integration of these systems with environmental, occupational health and safety, information security, and other management systems depending on the context and focus of the organization. Even more impactful changes are due to be published by the International Organization for Standardization (ISO) in 2024 as amendments to international standards for management systems. Expectedly, they are mainly related to climate action changes. At present, the integration of management systems at the University of Ruse, Bulgaria, involves such aspects as innovation management, business continuity, and knowledge management systems. The paper extends previously published research dealing with curriculum design and an integrated pedagogical approach to teaching and learning for the UN Sustainable Development Goals, coupled with integrated management systems. This paper highlights best practices, methodologies, and tools for knowledge management that can enhance the effect that management systems can exert on the performance of educational organizations in general, and more specifically - at the University of Ruse, Bulgaria.

Designing Technology Enhanced Climate Change Curriculum: Understanding the Instructional Needs of Pre-service Teachers.

Проектиране на технологично подобрени учебни програми за промените в климата: разбиране на нуждите от обучение на бъдещи учители

6th IITEE 2024 - International Instructional Technologies Engineering Education, 27-28 March 2024, Ege University, Izmir, Türkiye 

ABSTRACT ONLY

Abstract: Pre-service teachers are effective agents of change in the classrooms of the future. Character and values about socioscientific issues such as climate change are important factors that influence decision making regarding these matters. However, literature indicates that the initiatives towards enhancing the pedagogical skills as well as the character and values of preservice teachers for informed decision making are scarce. Therefore, this study aims to conduct a needs analysis of preservice teachers regarding climate change education. A total of 270 pre-service teachers from Bulgaria, Türkiye, Latvia and Lithuania completed a questionnaire consisting of 4 open-ended and 13 closed-ended questions, divided into three subdimensions: a) character and values regarding climate change, b) preparedness to teach climate change, c) technologies for teaching climate change. The results indicated that the pre-service teachers strongly agreed that climate change affects all of us and can disrupt the balance in nature. Only 1 respondent thought that not enough work has been done on climate change and about 25% of the respondents try to consider different opinions when making decisions on the issue. Although most respondents believe that teaching about climate change is important (n=234), only 61 respondents indicated that they have taken a course on climate change and only 82 respondents feel confident in teaching about climate change. The results also indicated that they get information about climate change mostly from social media and news, and 177 respondents indicated that they have never used information and communication technologies to learn about climate change. Based on the findings, we provide implications for the development of technology-enhanced climate change curricula.

Keywords: climate change education curriculum, character and values, need analysis, pre-service teachers.

Abstract: The Plan – Do – Check – Act (PDCA) cycle is the basis of the process approach applied in ISO management system standards. The experience gained in working with management systems and summarized in the author’s monograph have been creatively adapted and applied in the analysis of the requirements of ISO/IEC 42001:2023 - the first standard for artificial intelligence management systems.

This paper presents a method for determining the type of each requirement of the ISO/IEC 42001:2023 standard in relation to the PDCA cycle. The application of the PDCA cycle is demonstrated for selected processes and is used for creating process flowcharts. Further on they can serve as the foundations for developing relevant documented procedures that comprise the artificial intelligence management system.

AIP Conf. Proc. 3063, 060016 (2024); https://doi.org/10.1063/5.0195813 

Abstract: Quality management systems enable organizations to work more effectively and efficiently, improve their image, and enhance the satisfaction of their customers and other interested parties. The automotive industry is an industrial sector characterized by stricter requirements for quality management systems. The requirements of ISO 9001:2015 are used as a basis to which the requirements of IATF 16949:2916 are added. To keep up with current trends, the International Automotive Task Force (IATF) periodically publishes IATF 16949:2016 Sanctioned Interpretations (SIs). Depending on the organization's customers, a set of original equipment manufacturer (OEM) requirements are superimposed on the abovementioned set. The wide variety of requirements and their sources mate it difficult for the users and managers of quality management systems to track, monitor, take into consideration, update and integrate all such requirements into the management system of their organization. This paper presents a model designated to integrate these and other requirements in order to ensure conformity to requirements, effectiveness of processes, and customer satisfaction.

Abstract: Educational accreditation guarantees the quality of the educational processes, products, and services. Both the National Evaluation and Accreditation Agency (NEAA) in Bulgaria and the Romanian Agency for Quality Assurance in Higher Education (ARACIS) in Romania are members of the European Association for Quality Assurance in Higher Education ENQA). They follow strict professional standards, methodologies, procedures, and criteria. It is common that the quality management systems in universities are based on ISO 9001. The specific standard for educational organizations such as universities and research institutes ISO 21001 is far less popular than ISO 9001. The purpose of this paper is to highlight opportunities for improvement of the internal quality management systems of educational organizations based on international standards.

Keywords: standardization; accreditation; ISO standards; National Evaluation and Accreditation Agency (NEAA), Bulgaria; Romanian Agency for Quality Assurance in Higher Education (ARACIS).

Proceedings of University of Ruse - 2023, volume 62, book 9.1, pp.1 9-24.

Abstract: The paper presents methodology for pilot assessment of higher education teachers, instructional technologies design materials and e-learning platform. The learning materials for instructional technologies design and e-learning space were developed under the project “HE Teachers and Institutions and Instructional Technology (HIIT)”, Erasmus+ programm; Action type KA220-HED - Cooperation partnerships in higher education. The methodology for pilot testing includes two phases: The first one – with 105 HE STEM teachers and the second 24 of them will put the skills into practice with interaction with 480 students from the 4 Universities, partners in the project. A blended approach has been selected for the external piloting of the platform and training contents of the HIIT project. The main purpose of the HIIT-Pilot Survey-Teachers is to get first-hand feedback from the 105 teachers as users on the online learning space and the learning content that the HIIT consortium will make available to all HE engineering teachers and professionals. From the participants in the piloting evaluation 8 (2 per pilot country) will be selected for a guided interview/dialogue, to gain deeper insight in their experience with the programme, learning content and eplatform. A total of 24 HE teachers from the participants (6 per university partner) who participated in the learning activity and/or pilot testing will be mobilized to apply the skills and competences acquired and apply at least one of the tools in their online teaching activity. This will allow partners to assess and evaluate the impact on students in a reallife teaching environment.

Keywords: Instructional Technologies, Pilot Testing Methodology, Innovative Approaches.

Съображения относно източниците на грешки при експерименталното определяне на свиване

Fiability & Durability / Fiabilitate si Durabilitate. May 2023, Issue 1, p. 29-32. 4p.

Abstract: The compression request of some materials sintered at ambient temperature generally presents a macrostructural quasi-homogeneity and quasi-isotropy and inhomogeneities appear due to the presence of pores in the structure. A separate investigation is done on the sample to highlight the defects in the structure. Therefore, before proceeding to the tests, the operator is obliged to know the nature of the material, the mechanical processing undergone and the thermal treatments undergone. Only following these initial data will the operator choose the appropriate method of submission to the request, so that experimental errors are minimal.

Keywords: inhomogeneities, sintered materials, compression, experimental errors.

Abstract: The aim of this paper is to share the experience gained from an early adoption of the ISO 56000 series of standards for innovation management systems. The University of Ruse is among the first universities in Bulgaria to implement an ISO 9001 quality management system. Later this system is updated and extended with elements of ISO 21001:2018- management systems for educational organizations. Since 2020 the Technology Transfer and Intellectual Property Centre (TTIPC) at the University of Ruse has implemented a number of requirements and guidelines of the ISO 56000 series of standards. The foundation of the integrated management system is ISO 56002:2019 with guidance for innovation management. The principles for innovation management from ISO 56000:2020 are being followed while implementing key methods and tools from ISO 56003:2019 for innovation partnership, ISO/TR 56004:2019 for innovation management assessment, ISO 56005:2020 for intellectual property management, and ISO 56006:2021 for strategic intelligence.

Abstract: This case study focuses on alignment. We investigate using the 'True NORTH' method (Truly simple, Narrative, Objective, Restrictions, Tactical constraints, Here is a place to start) inspired by the military commander's intent method.

This method is applied in a Bulgarian university trying to overcome challenges post-COVID: face time, low involvement levels of professors and students alike, additional stress from being reachable anytime, anywhere, etc.

This tool and the lessons learned from the case study can be applied in any organization working on getting alignment on innovation objectives. The tool 'True NORTH' is supported by easy-to-use checklists and videos. This tool (and similar tools) could help innovation teams to be better aligned to achieve innovation objectives by following precise and meaningful action plans. This would reduce stress and frustration for both employees and top management. Clarity and alignment make the innovation process easier and more effective.

Abstract: The traditional auditor training is based on auditor courses lasting from a day to a full week depending on their complexity and scope. The University of Ruse “Angel Kanchev” has more than 20 years of experience in training auditors within the courses “Auditing Management Systems” and “Auditor Practice”. The lectures and exercise are based on the international standard ISO 19011 provide key competences to the bachelor degree students in “Quality Management and Metrology” and the master degree students in “Quality Management”.

The possibility to carry out remote audits was just a good idea until the COVID-19 pandemic. The need to audit remotely has been used as an opportunity to maintain the educational process and to build a new skill set. The experience gained in recent years has extended traditional education with digital methods and tools, and has turned it into a successful model for blended learning.

Abstract: The Purpose of this paper is to present the Plan – Do – Check – Act (PDCA) Cycle which is also called the Deming cycle. This approach to organizing systems, processes, activities and operations dominates a large number of standards published by the International Organization for Standardization (ISO). The research is focused on some of the most popular management system standards as evidenced by the most recent ISO Survey data. The standard with requirements for quality management systems – ISO 9001:2015, is used as a basis, and the other management system standards are compared to it based on their clauses aligned to the PDCA cycle. The research results suggest that knowing and practicing the PDCA cycle can unlock the secrets of ISO management system standards.

Abstract: When the term “quality” is mentioned in a conversation or a commercial advertisement it usually evokes positive connotations. Nevertheless, everyone’s perception of “quality” is unique regardless of the fact that the term as such is defined in ISO 9000:2015. Chronologically, the ISO 9000 series of standards are the progression of total quality management. And yet, for perfectionists and really devoted quality managers, a certified quality management system is only a starting point on a much longer or even endless journey towards overall excellence. The present paper aims to pinpoint the similarities and the major differences between total quality management, ISO 9000 series of standards, and excellence models.

Abstract:  Machine Learning algorithms have demonstrated their ability to model complex processes that are otherwise impossible to model analytically or through standard techniques. However, the amount of data and more importantly, the data quality, are critical factors for obtaining a good performance with such algorithms. This two-part paper will present an experimental dataset and will discuss several commonly used Machine Learning algorithms adequate for such problems. In the first part of the paper an introduction to several algorithms will be given; the inputs of the algorithms and some special constraints and limitations will be introduced.

Keywords: Machine Learning algorithms, Clay, Ash, Compressive strength, Density.

Abstract:  It is a fact that engineering properties of the building materials are particularly difficult to model analytically. Given the importance of their values in any application, it is critical to have an estimation of every engineering parameter that is required. This two-part paper will present a dataset containing three engineering properties of some new materials obtained through recycling waste from petroleum industry and from coal-based power. The second part of the paper will present the application of several Machine Learning algorithms to the dataset mentioned above. The performance of each model was assessed and discussed. It was found that Bagging (with a Decision Tree based algorithm) and XGBoost algorithm have the best performance.

Цветелин Георгиев, Данко Тонев. Влияние на организационната култура върху системите за управление на качеството

The Influence of Organizational Culture on Quality Management Systems

ХХХIII Национална научно-практическа конференция "Качеството - за по-добър живот ’ 2022", София.

Резюме: Съвременните системи за управление на качеството се основават на стандартите от серията ISO 9000. Въпреки, че изискванията на ISO 9001:2015 са общи, те се прилагат по уникален начин от всяка организация в зависимост от нейния вътрешен и външен контекст, стила на лидерство и мотивацията на персонала. Тези фактори формират организационната култура и взаимно си въздействат с нея. Многобройни са книгите, научните изследвания и публикувани статии, свързани с организационната култура, но до 2022 год. нямаше официални указания от ISO как да се осъзнава, оценява и подобрява организационната култура. Новите указания на ISO 10010:2022 могат да се използват за създаване на въпросници, които да разкрият допълнителни възможности за подобряване на системата за управление на качеството.

Ключови думи: култура по качество; системи за управление на качеството; организационна култура; ISO 10010:2022; ISO 9001:2015.

Tzvetelin Gueorguiev, Danko Tonev, Svetlin Parvanov. A Study of Measurement Systems Analysis by Attributes

Изследване на анализ на измервателната система по неизмерими показатели

2022 8th International Conference on Energy Efficiency and Agricultural Engineering (EE&AE), 2022. ISBN 978-1-6654-0708-3. DOI: 10.1109/EEAE53789.2022.9831252

Abstract: The paper presents a critical measurement systems analysis (MSA) of the implementation of "go-no go" gauges for control of mechanical parts. The MSA by attributes is generally overlooked when compared to MSA by variables. Nevertheless, this type of MSA is especially useful when applied in mass production where the use of variable gauges is time-consuming and costly. The outcomes of the study can be adapted to similar measurement systems analysis for other manufacturing processes and mechanical parts.

Tzvetelin Gueorguiev, Boris Sakakushev. The Case of Implementing ISO 21001 at the University of Ruse

Казусът на прилагане на ISO 21001 в Русенския университет

Proceedings of the International Scientific & Business Quality Congress "Effective Education & Quality Management - Key Factor for Success", June 29-30, 2021, Belgrade, Serbia. pp. 271-276.

Abstract: This paper presents the lessons learned and the main outputs from the process of transitioning from an ISO 9001-based quality management system to an ISO 21001-based system. The University of Ruse has developed, established and implemented its quality management system in 2004 when it was based on the requirements of ISO 9001:2000. Since then, the internal quality management system of the university has undergone multiple internal and external audits leading to its continual improvement. Some of the improvements were based on the two editions of the International Workshop Agreement IWA “Quality management systems - Guidelines for the application of ISO 9001:2000 in education”. In 2017, the University of Ruse has developed a special project focused on adapting its system to ISO/DIS 21001:2017 “Educational organizations - Management systems for educational organizations - Requirements with guidance for use”. In 2018 the first edition of ISO 21001 was published, and later that year it became a Bulgarian National Standard (BDS). Throughout 2019 teams from all faculties worked on updating the existing quality management system to the requirements of ISO 21001:2018 and also aligned the internal management system to the requirements of the National Evaluation and Accreditation Agency in Bulgaria. This paper intends to provide local context and to convey practical experience and tips to educational organizations that intend to implement ISO 21001.

Keywords: quality management systems, ISO 21001, case study, improvement, University of Ruse.

Tzvetelin Gueorguiev, Irina Kostadinova. ISO Standards Do Good: A New Perspective on Sustainable Development Goals

Стандартите на ISO правят добро: нова гледна точка към целите за устойчиво развитие (на ООН)

Proceedings of the 13th International Joint Conference on Knowledge Discovery, Knowledge Engineering and Knowledge Management - KMIS, 2021, No. 3, pp.133-137. ISBN:978-989-758-533-3. DOI: 10.5220/0010658000003064.

Abstract: The paper presents a new perspective to looking at ISO standards. Standards are usually considered as best practices or state-of-the-art industrial norms. For some, they are a source of vital information, and for others- standards are inhibitors for human creativity and innovation. Regardless of personal opinions and preferences, the greater good should unite humankind in pursuit of sustainability. In 2015, the United Nations (UN) adopted 17 Sustainable Development Goals (SDGs) as part of its 2030 Agenda for Sustainable Development. In 2018, ISO engaged with its contribution to the UN SDGs. This paper focuses on the relationship between SDGs and some of the most popular ISO standards for management systems.

Multicultural investigation of the students' acceptance of using digital learning materials in laboratory classes

Мултикултурно изследване на възприемането на студентите на използването на цифрови обучителни материали в лабораторни упражнения

Computer Applications in Engineering Education, John Wiley and Sons Inc., No. 29 (4), pp. 883-896. ISBN 1099-0542. DOI: 10.1002/cae.22322. Impact factor (2021): 2.109 / Impact factor: 1.532 / 2020 (WoS)

Abstract: The digitalization of education is a continuously developing process, aimed at the use of information and communication technologies. However, engineering education utilizes several forms of learning, with laboratory experiments being one of them. The use of digital learning materials (DLM) in labs is still limited due to numerous existing factors. This study investigates students' acceptance of using DLM during laboratory exercises in three universities located in Turkey, Poland, and Bulgaria. A questionnaire was prepared, and a survey was conducted among 625 learners. They were divided into eight categories, based on their engineering area and country. The survey results demonstrate that there is a strong correlation between the students' opinion on DLM and the use of DLM by their lab instructors, which means that their acceptance could be increased if more DLM are integrated in lab courses. The analysis of the questionnaire results also showed that there is a significant difference in the students' opinion on DLM, depending on the engineering area. Students of Food, Chemistry, and Electrical engineering rated the use of DLM quite high (above 4.0 out of 5), followed by the Civil engineering students with average results between 3.5 and 4.0. Respondents involved in Textile, Bio, and Machine engineering were the most skeptical (<3.5). Furthermore, their opinions covered a wide range from “Strongly disagree” to “Strongly agree.”.

Proceedings of the 15th International Conference “Standardization, prototypes and Quality: A Means of Balkan Countries’ Collaboration”, Trakya University, Edirne, Turkey, 2019, pp. 471-478. ISBN 978-975-374-247-4.

Abstract: The purpose of the paper is to present a comparative analysis of the two latest editions of the standard ISO 9004- Quality management - Quality of an organization - Guidance to achieve sustained success. The key findings are based on case studies of two Bulgarian organizations. The need to research this topic is justified by the fact that there is no benchmark between quality management systems certified to ISO 9001:2015. The research hypothesis is that ISO 9004:2018 can be used to measure the maturity of quality management systems, and at a later stage as a guideline for best practices. The intent is to research two different industry sectors- manufacturing of metal tubes and production of pharmaceuticals. The maturity levels of the processes in both organizations have been assessed using a specially designed Excel form. Data has been gathered based on face-to-face interviews with quality managers and process owners at the two surveyed organizations. The comparative analysis uncovers opportunities for improvement of the quality management systems. Recommendations for quality improvement have been made based on a gap analysis of data from two maturity audits of the quality management systems. All Level 4 and Level 5 processes serve as best practices to organization from the same industry sector, or even from substantially different industries.

Keywords: Quality management systems, sustained success, sustainable development goals, ISO 9004:2018, ISO 9004:2009.

Профил на натоварването на типични жилищни сгради в България

4th International Scientific Conference SEA-CONF 2018 IOP Publishing, IOP Conf. Series: Earth and Environmental Science 172 (2018) 012035, pp. 1-6. ISSN 1755-1307. DOI: 10.1088/1755-1315/172/1/012035.

Abstract: In the current market design, the increasing use of renewable energy sources for electricity generation leads to new challenges in balancing supply and demand. While households are responsible for 29% of total electricity demand in Europe, a good understanding of their consumption and load profiles is missing. Households have become one of the most crucial factors shaping the management of developments towards sustainability. The development and implementation of effective policies for promoting energy efficiency in the household sector has been an emerging target of the EU. Recent analyses of Bulgarian households show this type of housing as the most statistically significant variable to impact electricity savings. This study deals with the statistical analysis of electric consumption. Statistical evaluations of electricity consumption in a typical apartment building have been obtained in the research. Mathematical models of the investigated loads have been developed. The research is based on the periodic results and the object of investigation is a typical residential block of flats in Ruse, Bulgaria. The average daily energy consumption during the weekdays and weekends is presented and analysed in the paper.

Цветелин Георгиев. Установяване на подхода за мислене, основано на риска, на ниво университет

Establishing a Risk-Based Thinking Approach at University Level

International Journal “Knowledge”, Twelfth International Scientific Conference “Knowledge Without Borders”, 31.3-2.4.2017, Vrnjacka Banja, Serbia, No. 22.3, pp. 887-892. ISSN 2545-4439, ISSN 1857-923X.

Abstract: Risk-based thinking (RBT) is a hot topic in the field of quality management systems (QMS). It has been introduced in the latest edition of ISO 9001:2015 Quality Management Systems – Requirements. This approach has been implicit in the previous editions of the standard ISO 9001 but nowadays it attracts more attention due to a number of factors. First and foremost, one must point out the increasing complexity of the environment we live in and in which organizations operate. In QMS, this environment is referred to as the context of the organization. Another contributing factor is the importance of goal-setting and the deployment of the organizational mission, vision, strategy and policy at the relevant levels within the organization. The International Organization for Standardization (ISO) has published a set of international standards for risk management. They include a range of risk-related topics like vocabulary, principles and guidelines, risk assessment techniques, etc. The most recent update relates to the latest revision of the risk management at organizational level. ISO 31000:2018 provides a common approach to managing any type of risk and is not industry or sector specific. Hence, its more general guidelines have to be adapted to the context of the educational organization, and the requirements of ISO 21001. This paper presents the main elements of the documented procedure for applying RBT. It is developed in order to support the decision-making process at all levels of the University of Ruse “Angel Kanchev’. In addition, guidelines on how to audit the effectiveness and efficiency of the implementation of this procedure are given.

Keywords: Risk-Based Thinking (RBT), Quality Management System (QMS), higher education institution (HEI).

Abstract: One year after the publication of the fifth edition of ISO 9001 – the international standard for quality management systems – two distinct trends can be observed. On one hand, there is a ‘wind of change’ which has modified the quality management principles and the structure of the standard ISO 9001, new requirements have been introduced, as well as new ideas, terms and interpretations. On the other hand, there is a sense of a standstill induced by the relaxed deadline for transition- September 2018.

Juliana Popova, Tsvetelina Harakchiyska, Tzvetelin Gueorguiev. Good practices of Knowledge Management at the University of Ruse, Bulgaria

Добри практики за управление на знанията в Русенския университет, България

Knowledge - International Journal Scientific Papers Vol. 13.1 “Teacher of the Future”, Ninth International Scientific Conference, 17-19.6.2016, Durres, Republic of Albania, Vol. 13.1, pp. 71-75. ISSN 1857-92.

Abstract: Knowledge management is a key asset and plays a pivotal role in modern society. It is crucial to organizations of any type and size, but its importance is crucial in educational institutions in Europe. The European Commission promotes ‘close, effective links between education, research, and innovation – the three sides of the ‘knowledge triangle’.’ Knowledge management is a main topic also for UNESCO which ‘works to create inclusive knowledge societies and empower local communities by increasing access to and preservation and sharing of information and knowledge’. This UNESCO policy is based on four pillars: freedom of expression; universal access to information and knowledge; respect for cultural and linguistic diversity; and quality education for all.’ The International organization for standardization, ISO, also has issued standards such as the popular ISO 9000 series which deal with knowledge management. The latest edition of ISO 9001:2015 in its clause 7.1.6 Organizational knowledge devotes more specific attention to knowledge management than the previously used Competence of human resources. In addition, clause 6.7.2 Knowledge, and 9.4 Learning of ISO 9004:2009 give more clues how universities and schools can benefit from implementing a quality management system standard for achieving sustainable success. This context defines the conditions in which a European VET (Vocational Education and Training) project DESK (Develop, Evaluate and Save Knowledge) has united the strengths of German, Austrian, Slovenian and Bulgarian educational institutions. The project deals with defining critical knowledge for the partner organizations, implementing custom tailored solutions to knowledge management issues, and disseminating good practices in order to assure better knowledge management, to propose national guidelines, and to help introduce the successful cases at European level.

Keywords:  knowledge management, develop, evaluate and save knowledge, DESK project.

Stefano Brumat (eds.) "DIAnet International School Proceedings 2015. The role of cultural heritage for the sustainable development of the Danube Region, Gorizia 14th-23rd March 2015", Trieste, EUT Edizioni Università di Trieste, Italy. pp. 133-149. ISBN 978-88-8303-669-9, eISBN 978-88-8303-670-5.

Abstract: The project “Former Socialist Countries Open their Past to Europe” (SCOPE) focuses on gathering cultural heritage (CH) in the form of documents and personal testimonies from the former socialist countries (FSC) in the Danube Region. The main goals are to create an extensive database (DB) of the publicly available and newly collected documents, and to develop a user-friendly application for data search and analysis. The collection of available documents will be examined by group of historians to select significant CH movements on a specific geographical area. Innovative tools, SCOPE website and application, will provide effective research and analysis of documents in a new, standardized database. SCOPE tools allow quick searching of all available documents using keywords or phrases; classification of results according to geographical position/dates/types/ historical impact; and graphical illustration of activities against the socialist/communist regimes through the defined period of time. The novelty of the project is the use of the ‘citizen science’ approach to acquire personal testimonies of cultural opposition movements during the communist period through SCOPE tools. An interactive part of SCOPE application will collect users’ feedback in order to analyze if the documents serve the purpose of awareness raising on the anti-communist past among EU citizens.

Keywords: cultural heritage, socialism, communism, opposition movements, SCOPE.

Цветелин Георгиев, Петър Ангелов. Дигитален модел на взаимодействията между процеси от ISO 9001

A Digital Model of the Interaction between ISO 9001 Processes

Научни трудове на Русенския университет - 2014, том 53, серия 2, стр. 78-83. ISSN 1311-3321 (print), ISSN 2535-1028 (CD-ROM), ISSN 2603-4123 (on-line).

Abstract: The paper presents a solution for describing the interaction between ISO 9001 processes. The model which is incorporated in the international standard is too general for practical purposes. Using a 2D graph can be counterproductive because the network of links is complex and tangled. The authors propose a 3D model developed in SolidWorks which provides zooming, rotating, and panning functions and enhances the understanding of interactions between processes.
