RECENT J. (2024), 73:080-091 https://doi.org/10.31926/RECENT.2024.73.080 Abstract Technical textiles and other high-value goods are seeing rising demand on international marketplaces. Many nations have shifted their manufacturing focus to these items in the last decade in an effort to boost their economic standing and compete on a global scale. This study seeks to shed light on the current state of the textile industry in Türkiye, specifically in Bursa, one of the textile hubs, and its shift towards technical textiles with higher value-added products. We take a look at the current product trade volumes around the world, import-export statistics, and Türkiye's standing in this field. Also covered are the latest developments in the industry as well as the state of the market for technical textiles. Technical textile exports to international markets reached almost $118 billion, up 3.38 percent from the previous year. The total value of Turkish exports in 2021 was 2,413 billion dollars, down 12.91 percent from the previous year. The results of the Grubel-Lloyd Index calculation for the technical textile product groups in Türkiye show that, with a few exceptions, intra-industry trade is bidirectional. All technical textile products had an average index value of 0.7968. The twelve main types of technical textiles are based on the many uses they serve. By 2028, the Mobiltech, Indutech, and Packtech subcategories of technical textiles are expected to have the most significant trade items.

RECENT J. (2024), 73:092-100 https://doi.org/10.31926/RECENT.2024.73.092 Abstract Cluster governance is about identification and establishment of an organisational structure and organised efforts for managing relations, communication, flow and share of information and implementation of activities for achieving commonly shared vision of the cluster. Identification of the cluster organisational structure does not have any commonly agreed or accepted rules when cluster cases are reviewed. Additionally, variety of factors implies on success of organisational structures and their effectiveness. It is key to elaborate on maturity level of the cluster and level of operational capacity and resources. In most cases organisational structures or governance models of clusters linked with cluster management capacity and skills. In other words setting up a well-functioning cluster governance structure is highly related with well-functioning cluster coordination unit which is mostly known as cluster management team, responsible for a boards representing cluster profile as a whole. Identification of appropriate organisational structure for Bursa Technical Textile and Composite Materials Cluster has vital importance for the success of the cluster. The cluster has a variety of actors between large, medium and small scale companies, OEMs, strong universities, OIZs, stakeholders and public institutions where all actors have their own expectations, inputs, organisational rules. Therefore, establishment and launch of cluster is at formal bases important for continuation of cluster activities and implementation of the cluster strategy at collaborative and institutionalised way. Word formal does not mean establishment of formal body from the beginning of cluster development stages, however it is more about coordinating cluster activities for implementing the strategy has to be coordinated by an organisation and cluster coordination unit with full time team(s) work at daily basis to coordinate identified actions for the cluster.

RECENT J. (2024), 73:101-113 https://doi.org/10.31926/RECENT.2024.73.101 Abstract Strategic priorities were determined by taking into account all the data and findings collected within the scope of this study, and the cluster vision and mission were presented together with the cluster strategy. It is built on three key strategic pillars of innovation, productivity, and internationalization and is complemented by three supporting strategies: skills and knowledge development, network development, and cluster promotion and branding. This study, which is one of the building blocks of the Technical Textile and Composite Materials Cluster, can be used not only as a road map but also as one of the basic documents of clusters and as a source for the development of new cluster projects and actions. The Bursa Technical Textile and Composite Materials Cluster has great opportunities, and it has been seen that it is possible to achieve its goals with the determined implementation of the cluster action plan.

RECENT J. (2024), 73:114-121 https://doi.org/10.31926/RECENT.2024.73.114 Abstract New Generation Hybrid and Electric vehicle production is rapidly increasing worldwide as a cleaner and sustainable alternative. This rapid change has significantly increased the needs for maintenance and repair of these vehicles. In order to meet this need, infrastructure and material development studies for new generation vehicle technologies trainings are intensively carried out all over the world. In this study, in-service training given to 257 vocational high school teachers at the New Generation Vehicles vocational qualification center of excellence, established with EU funds in Türkiye, was evaluated. Experimental research method with control group was used in the trainings to determine the contribution of the training programs developed and the infrastructure created to the learning performance. Data of the study; it was evaluated with a pre-test-post-test exam and Likert-scale survey measuring changes in knowledge-skills-perception. As a result of academic measurements: it has been observed that trainings using new content and center of excellence infrastructure increased teachers' academic success by 91%, and the increase in performance, which consists of meeting the needs in their perception-skills-and expectations, was 20.41% on average. The results obtained show that the content, training material and infrastructure developed within the scope of the project make significant contributions to people's learning and teaching performances.

RECENT J. (2024), 73:122-129 https://doi.org/10.31926/RECENT.2024.73.122 Abstract In the car manufacturing industry, the laser cutting process is frequently used. For this reason, establishing risks and preventing them is a permanent concern of quality management and more. To prioritize these risks, a series of models and methods established by research in the field are applied. Two case studies are presented in the paper, in order to evaluate and rank the failure modes that could occur in the laser cutting process. In the first, the classic FMEA method is used, and in the second the TOPSIS method. Failure mode and effect analysis (FMEA) is one of the well-known quality management techniques that is used for continuous improvement in product or process design. The approach proposed by the method is simple, but there are some limitations in obtaining a good estimate of failure rates. Thus, a new risk assessment system based on the TOPSIS theory is necessary, at the end of the paper comparing the results obtained by the two methods. This work can also serve as a failure prevention guide those who perform the laser cutting operation.

RECENT J. (2024), 73:130-137 https://doi.org/10.31926/RECENT.2024.73.130 Abstract Both hard turning and superfinishing are manufacturing processes aiming to obtain high-quality surfaces, which lead to the fulfilment of high-quality requirements of the parts used in industrial applications subject to high loads. Using these two processes leads to very smooth surfaces, with low roughness, necessary to increase the lifetime of the parts. The aim of the experiment is to determine the capability of hard turning process, in achieving similar performances to superfinishing process, under certain technological conditions. Conical rolling elements were used in experiments, analysing the surface integrity, i.e. surface roughness, both after longitudinal and frontal hard turning, as well as after superfinishing. The results show that using hard turning as finishing process, a very good surface quality can be obtained, similar to those obtained by superfinishing, in terms of roughness.
