    • An assessment of energy efficiency measures in a public building in Albania in the prospect of cost and emissions reduction

      pg(s) 47-49

      The building sector in our country has an important share of energy consumption. According to Eurostat data, final energy consumption in the residential sector was estimated about 35 % of the total consumption. On the other hand about 75% of the electricity consumption takes place in the building sector. It should be noted that currently this sector faces many challenge, as the quality of energy supply (heating) in public buildings and the residential sector remains at low rates. Nevertheless, reducing energy consumption is one of the main targets set in the National Energy Strategy 2018-2030. By 2030 this target suggests 15.5 % of the energy reduction. This study has at its core the assessment of energy consumption in a public building placed in the city of Durres. Determining the typology and thermophysical characteristics of the building is of primary importance. The evaluation of the energy performance of the building in the dynamic regime was carried out through the Hourly Energy Analysis (HAP) software. The implementation of energy efficiency measures is carried out taking into account the energy and cost criteria. A cost analysis of EE measures was performed using the dynamic Net Present Value method.

    • Improvement of the production processes based on the lean methodology

      pg(s) 50-53

      The project for improvement of the production process based on the Lean methodology in SMELT-ING DOO was implemented in four phases (mini projects). The detailed analysis of the work orders in the period of 9 months provided clear picture of the current situation. With the defined methodology and through mutual meetings with the upper management and the employees of the company, the project team managed to introduce and implement the following mini projects: improved visualisation, digital work order, implementation of 5S and portable tools trolley. All these mini projects have improved the organization of the production process and helped the process of waste
      elimination in the company.

    • Eco innovations – the foundation of sustainable regional bio-sector

      pg(s) 54-57

      Mankind faces a number of challenges in the 21st century. Many of them are related to the achievement of the goals and ideas set in the concept of sustainable development of modern UN society. The bio-sector, which is developing within the borders of the Bulgarian economy, has undergone rapid development in the last few years. Many factors have influenced this process, the most sign ificant of which are: increased demand for organic products in international markets, high levels of public support for this type of production and the availability of favorable climatic conditions for their development. Innovation is the main tool for achieving competitiveness and economic growth at all levels – enterprise, industry, region or country. They are the fundamental means of improving people’s quality of life. The purpose of this report is to present the results of a survey conducted among bio-enterprises in the regions of Bulgaria and to show that the green innovation in the bio-sectors is the foundation for regional economic, social and environmental prosperity. The results of the study summarize the main directions for achieving regionally balanced sustainable development.

    • Supplier’s Reverse Logistics Process Management

      pg(s) 58-61

      Reverse logistics processes generate significant logistics costs if not optimized continuously and are often being undetermined. Logistics companies emphasize the necessity for optimization and process uniformization to its highest possible extent, while disadvantages as process duration, educated personnel, and unsatisfied consumers are reverse logistics barriers. For the paper research, the focus has been directed to reverse logistics process analysis at the location of a supplier on the Republic of Croatia logistics market. The case study consists of highlighting reverse logistics issues, on-site analysis, and possibilities to optimize time-consuming processes. Analysis has been provided throughout time measurement of individual reverse logistics process with suggestions for optimization.


    • A proposal for a basic structure of a business model for research management, with a focus on intelligent security systems within the scope of the quasar project

      pg(s) 62-65

      Joint research takes its place as a major innovation process. The aim is to build relationships through which to gain access to external sources of high technology (or other assets) and their integration into the products and services of business organizations.
      The establishment and operation of Competence Centers in our country, such as QUASAR, plays a leading role in planning, structuring and negotiating these relationships with universities, small high-tech companies, mid-market companies and large companies. The proper development of the business models of the Centers of Competence plays an essential role in this direction
      The purpose of this study is to present the impact of business models on two dimensions of joint research: cooperation as an alternative to successful relationships and business models as an effective tool for assessing the portfolio of opportunities and risk allocation.

    • Musical thinking of musicians-educators in the context of artistic interpretive culture

      pg(s) 69-72

      The art of interpretation was being developed intensively at a time when composer and performer were tend to be more and more independence, and the performer gain the opportunity to interpret the works of other authors. The formation of the interpretive culture of a music teacher affects the effectiveness of the pedagogical process and conveying to students the valuable meanings of art. Achieving a good result in the process of creating interpretation helps musical thinking, which consists in processing, evaluating and creating new musical information and is expressed in the ability to understand and analyze what is heard, mentally imagine and operate elements of musical language, evaluate music and sound quality. The article explores the artistic and musical thinking of musicians-teachers in the context of interpretive culture. The article defines musical thinking as a process of modeling the system of relations of the subject to reality realized in intonation. Artistic thinking is a necessary prerequisite for any other mental activity of a musician-performer, because this mental activity is his reworked result. Musical thinking must be studied simultaneously from three aspects: as an example of identifying the general patterns of any thinking, as one of the types of artistic thinking and as a manifestation of specific characteristics of musical information.
