As it is known, the ultimate goal of clothing industries is to produce and deliver products at the desired quality level by the customers. While this situation is being realized, the sustainability of the companies needs to use the resources at the optimum level. The human factor is at the top of the companies' resources, and it is aimed that the operators will actively participate in the production processes. Within the scope of the "line balancing" method, which is one of the traditional production management techniques, the number of employees, working time, and standard time of each process are taken into consideration. However, it is obvious that a new kind of process management system should be developed and different variables should be put into effect in the clothing environment whose dynamics change rapidly, has a lot of product variety, and each step is dependent on people. Within the scope of this study, it is aimed to create an "operator competence analysis" consisting of various sub-criteria for the clothing industry. In this way, it is thought that a production that is more compatible with customer requests (quality, deadline, etc.) will be achieved by improving the operators and determining the appropriate operator in a very short period of time. It is aimed to develop an objective analysis and evaluation system in this study. The suitability of the sewing operators, who are the main actors of productivity in sewing enterprises, has been handled multidimensionally as an alternative to existing methods. In today's conditions, where production quantities depending on the model are decreasing rapidly, a 15% reduction in model setup times has been achieved at the TYH İzmir branch, where this operator competence system developed for production lines that need to be much more agile and flexible. With this study, it is thought that a Competency Analysis System (CAS) that is much more suitable for the realities of the ready-made clothing industry, which is one of the sectors where labor-intensive production is most intense, has been gained.

The Covid-19 pandemic during 2020 and 2021 forced many companies and organizations to directly shift to remote working. The main goal of this research paper is to study the effect of the pandemic restrictions on software engineering teams who have been implementing Agile methodology already or recently adopting it in their projects after the pandemic. The survey was distributed to people who work on software engineering projects to get their feedback about how their work and production got affected by the pandemic. The survey focused on six main areas which are Agile adoption, the impact in Agile manifesto, the delivery of the project, methods and tools used, skills gained and improved, and last area was the challenges and advantages of the pandemic from participants’ point of view. We noticed that many software projects during the pandemic period adopt the Agile method, whether they have been utilizing it previously or adopting it recently during the pandemic period, due to its flexibility, adaptability, resilience, and responsiveness. We also found out that software development projects implementing Agile methodology are less affected by the pandemic, based on the participants' answers related to the main value of Agile and delivery of the project.

In order to avoid violent stream-wise and transverse oscillation in isolator, a fluidic control method was proposed. This method combines the boundary suction and the slot injection method together. For the sake of checking out the control effect of the concept, two contrast wind-tunnel experiments were completed in M0=4.92 hypersonic wind tunnel. According to the experiment results, as the shock train moving upstream, the mass flow rate of secondary flow increased and the slip line moving towards to the bottom wall, meanwhile a series of weak shocks generated by injection got stronger that increased the pressure upstream the shock train. The shock train interacted with upstream background shockwaves, and the travelling processes can be divided into 4 stages which were much sim-pler than that of uncontrolled flow. Although there was one unstable stage, the shock train behaved in a much milder manner with an oscillation frequency of 641Hz and the maximum oscillation power de-cayed to 20% of that of uncontrolled flow, and the maximum sustainable back pressure almost equal to that of uncontrolled flow.
