    Today’s guest no longer seeks just accommodation and food but a complete experience that includes physical, mental, and emotional well-being. This shift in expectations has prompted the hotel sector to innovate, offering wellness programs, mindfulness activities, and personalized services that cater to the holistic needs of guests. As a result, hotels are transforming into sanctuaries that prioritize the overall health and happiness of their guests. In this context, recreational activities in hotels play an increasingly important role as a means of preventing and promoting mental health. Therefore, this research aims to examine the impact of various recreational activities—such as yoga, fitness, water sports, hiking, and group games—on the psychological well-being of guests during their stay. With a quantitative questionnaire for guests, their levels of stress, anxiety, mood, and perception of their own well-being will be analyzed after participation in recreational programs. This research will provide valuable insights into how these activities contribute to improving mental health outcomes. By identifying effective recreational options, hotels can better cater to their guests' needs, ultimately increasing their seamless experience and satisfaction during their stay. Additionally, this paper will contribute to the development of targeted recreational programs that not only respond to the needs of different guest profiles but also foster a supportive environment for mental health. As a result, hotels may position themselves as leaders in promoting holistic well-being in the hotel sector

    Occurrence and mineralogical characterization of specularite in Damjan ore deposit, North Macedonia

    Get PDF
    In this paper are presented occurrence and mineralogical characterization of specularite from Damjan ore deposit. The straightforward identification of the studied mineral sample was enabled by SEM-EDS, XRF and XRPD methods. With these methods it can be seen that the phases present are calcite, specularite and quartz. Specularite crystals occur in the surface parts of the deposit. Specularite has a metallic gray to silvery appearance with a glittering luster and reddish streak. It shows a very smooth surface with reflection. The metallic luster is a result of the specific crystal formation of hematite. Manganese and aluminium substitute for Fe³⁺ in the specularite structure. Small amounts of Fe²⁺ and Mn2+ substitute for Ca²⁺ in the crystal lattice on calcite. The well-developed morphology of specularite suggests that it crystallized first. The finer-grained calcite likely formed later, filling the interstitial spaces between the earlier-formed specularite. Key words: specularite; calcite; quartz; Damja

    Get PDF
    This paper examines the modernization of shooting ranges through the implementation of ground-based modular platforms designed as smart target carrier systems. Traditional ranges that rely on static or semi-automatic targets are increasingly inadequate for the complex requirements of modern military and law enforcement training. The proposed platforms introduce mobility, modularity, and intelligent functionalities that enable more realistic and adaptive training scenarios. The systems integrate mobile robotics, hit-detection sensors, automated scoring, and real-time data transmission, which together provide objective feedback and reduce the need for manual target handling. Navigation solutions such as GPS, LIDAR, and SLAM algorithms support autonomous movement across different terrain types, while modular design ensures compatibility with advanced training infrastructures, including programmable and reactive target systems. The study highlights the capacity of these platforms to enhance training realism, improve safety standards, and increase operational efficiency. By reducing setup time, enabling dynamic reconfiguration of scenarios, and supporting scalable deployment, the proposed concept contributes to the digital transformation of shooting ranges. The findings position ground-based modular smart target carriers as a key component in the development of next-generation training facilities that align with evolving defense and security needs

    his paper applies the Six Sigma DMAIC methodology to improve the production of symmetric composite parts, in our case composite pipes, focusing on their quality requirement of high interior pressure resistance. The filament winding process has been utilized to enhance the industrial process by developing mathematical models of fiber movement paths, resulting in the creation of symmetrical composite parts like pipes and tanks. It analyzed the importance of the fiber winding angle while maintaining the other process factors that were taken to be constant. Based on the mathematical models created for fiber path and pipe design, symmetrical composite samples, or composite pipes, were made with different winding angles (45° and 90°). For all manufactured composite samples, laboratory tests were conducted on the hoop tensile strength to ensure they met the quality requirements for composite pipes, specifically their resistance to high internal pressure. The predicted behavior of symmetrical composite parts (composite pipes) was found to align with the results of the tests conducted on the produced samples. Keywords - Six Sigma, Mathematical models, Path design, Symmetric composites, Filament winding process, Composite pipes, Hoop tensile strengt

    :Determination of Activation Energy of Cyanet Ester and Epoxy Resins Using Dynamic Mechanical Analysis

    Get PDF
    The activation energy associated with the glass transition relaxation of thermosets has been determined by using the three-point bending clamp provided. In the present study, the dynamic mechanical analyzer NETZSCH Instruments DMA 242E was used to characterize two different types of thermoset resin. Each sample was given a linear heating speed of 5°C/min at four discrete frequencies in the temperature range RT °C to +250 °C.The activation energy for both transitions was determined by an Arrhenius plot from dynamic properties measured at different frequencies. The experimental results showed that the evaluation of activation energy is affected by the test frequency as well as the criterion by which the glass transition temperature (Tg ) is established. It has been found that the activation energy based on the loss tangent (tan δ) peak is more reliable than on the loss modulus (E”) peak. Keywords - Activation Energy, Dynamic Mechanical Analysis (DMA), Polymer Composites, Glass Transitio

    Get PDF
    Виновата лоза (Vitis vinifera L.) претставува една од најстарите и најзначајни земјоделски култури, но како и сите растителни видови, таа е изложена на болести, штетници и неповолни климатски фактори кои значително влијаат врз приносот и квалитетот на производот. Во современото лозарство, за заштита од овие ризици се применуваат различни средства за заштита на растенијата, меѓу кои најзастапени се пестицидите - фунгицидите, инсектицидите и хербицидите. Иако нивната употреба е од суштинско значење за одржување на продуктивноста и стабилноста на лозарското производство, истовремено претставува потенцијален извор на загадување на животната средина. Ова прегледно истражување има за цел да ги анализира причините, последиците и ризиците од примената на хемиските средства за заштита на виновата лоза, со посебен осврт на нивното влијание врз почвата, водата и воздухот
