Maturity of companies, organizational culture and costs are some of the major limiting factors for implementation of cost-effective six sigma methodology in Bosnian companies.  Purpose of this paper is to analyze possibilities of applying six sigma concept in a medium-sized company with 200 employees. Considering all characteristics of the company, in this case, implementation model was proposed and tested. The project included process monitoring using statistical process control charts for two different periods, before and after improvement. Dominant defect and its causes were identified and it was found out that the process was out of control. Implementation of improvement measures, dominant defect was eliminated but the process has remained out of control. As a conclusion, the test indicated that the model is effective but it takes more iteration to achieve the desired state.

The widespread deployment of AI systems has led to overlapping concerns around technological impact and governance, often resulting in conceptual ambiguities and policy confusion. We propose a structured and context-sensitive framework for addressing the ethical implications of artificial intelligence. We argue that ethical frameworks must distinguish between the intended domain of AI deployment and the scale of its societal effects.To resolve these tensions, we introduce a two-dimensional matrix based on (1) the extent of AI’s impact and (2) the scope of its governance, which together form four distinct ethical contexts. Within each quadrant, we explore specific risks, values, and regulatory considerations. This matrix not only clarifies the conceptual terrain of AI ethics but also offers a practical roadmap for anticipating ethical risks, developing normative guidance, and informing domain-specific governance strategies.Our goal is not to prescribe a single ethical doctrine but to provide decision-makers with a structured lens through which AI systems can be evaluated in context. This approach promotes adaptive and anticipatory governance while remaining responsive to local, institutional, and cultural variations.

This research explores the thermal performance of biomass-based composite panels enhanced with Phase Change Materials (PCM) for energy-efficient building applications. The experimental method under lab-controlled conditions was used to investigate thermal performances. Four samples of PCM-biomass-based composite were fabricated using encapsulated PCM, straw, and mortar as a binding material, and four sample without PCM as a reference. The effective thermal conductivity of each sample was determined using the guarded hot plate method under steady-state conditions. Results indicate that the incorporation of PCM does not significantly alter the thermal conductivity of the composite, but it enhances the material’s ability to store thermal energy. Compared to conventional construction materials, both the reference and PCM-enhanced samples exhibit superior thermal insulation properties, making them promising candidates for sustainable building applications. The findings suggest that optimizing PCM concentration and distribution could further enhance thermal performance, contributing to the development of passive energy-saving solutions.

Cybersecurity is an important topic for Industry 4.0, which will face a lot of non-traditional challenges before it can be fully implemented to help society. The objective of the study is to recognize recent cybersecurity trends, newly occurring threats and challenges as well as their potential solutions. The articles reviewed in the paper are found through science direct, Scopus, Semantic scholar and google scholar. After reviewing them, ideas from articles were grouped together to show how different articles had similar thoughts. Through the analysis of 70 articles, it was found that cybersecurity still needs a lot of improvement in order to efficiently implement Industrial Internet of Things (IIoT), especially since many articles underline the need for security-by-design approach, followed by regular updating. Key challenges are lack of awareness and security experts, increased cybercriminal and the fact that the chain is as only as strong as its weakest point. Some of the most important solutions include incorporating security into design, stronger encryption, regular updates to patch vulnerabilities and good prevention and detection mechanisms. Once cybersecurity challenges are overcome, Industry 4.0 will be able to bloom to its full extent.

In the past three years, the COVID-19 became a global health issue and had huge impact on education. This study investigates and compares the student performances after transition from face-to-face learning environment to online learning environments as a result of the spread of the pandemic. Data is collected from a large Bosnian public university and analyzed using statistical tools. In this study student success is defined as passing the course. The results showed that there is significant difference in the performances of students, and it is dependent on learning environment. Particularly, students who attended online classes have significantly higher-grade point averages.

This paper presents the design and the development of an EOD robot, with MVP characteristics. The design is based on a solid base structure with an arm manipulator attached to the base. The overall dimensions of the robot are 590x860x340 mm and it weighs 55kg. The robot is capable of towing heavy objects as well as lifting sensitive objects. The robot has a maximum horizontal reach of 1400 mm and a vertical reach of 1200 mm. The robot is tested according to guidelines developed in the U.S.A., as much as the conditions allowed. Briefly, the results can be summarized as follows: the setup time for the robot is 10 minutes, it can reach speeds up to 8 km/h, it has a towing capacity of 40kg and the maximum communication reach is 20 meters. Among successful tests, the weaknesses were also found which act as a guide for future designs and developments. These weaknesses are what MVP concepts are actually developed for.
