Women rising in the port industry: a multimethod approach to career barriers
No full textDespite an increase in the number of women employed in the port industry in recent years, women in this field encounter significant challenges that not only affect their business lives but also hinder their career advancement. Accordingly, this study aims to identify the views of women working in ports regarding these challenges and rank the barriers hindering their careers. Adopting a multimethod approach, the study used both narrative analysis and Fuzzy Analytic Hierarchy Process (AHP) as research methods. For the qualitative analysis, the barriers identified from the interviews were coded in accordance with the relevant literature, while their importance levels were determined by quantitative analysis. The barriers were grouped under four main categories as: male co-workers, harassment, port conditions, and feminine. While the interview results suggested that male co-worker related barriers were the most important, the Fuzzy AHP analysis indicated that harassment-related barriers were the most significant. Through in-depth qualitative and quantitative analysis and ranking of the data based on women's real-life stories, this study presents novel and comprehensive findings regarding the career barriers facing women port workers
The Effects of Wellness Recovery Action Plan Based Psychoeducation Program on the Psychosocial Health of Caregivers of Alzheimer’s Patients
No full textThe aim of the study is to examine the effect of Wellness Recovery Action Plan (WRAP) based psychoeducation program on health of caregivers of Alzheimer’s Disease (AD) patients. This is a quasi-experimental study of pre- and posttest, control group design. WRAP based psychoeducation was applied to the intervention group and compared with the standard caregiver education group and the control group. A total of 60 caregiver for AD patients constituted the sample. The data were collected with the perception of health, caregiver burden, and quality of life scales. It was found that there were no differences between the mean pre- and posttest scores of all group participants on the perception of health and caregiving burden scales (p >.05). Exclusively the increase in the quality of life score of the standard caregiver education group was statistically significant (p <.05). It was found that the WRAP-based psychoeducation program applied to the intervention group did not have an impact on the perception of health, caregiving burden, and quality of life of caregivers of AD patients
Enhanced electromagnetic wave absorption in biochar/yttrium iron garnet hybrid composites for electromagnetic interference shielding applications
No full textBiochar and biochar composites are versatile materials that can be used in many applications. In this study, biochar was prepared from sawdust and combined with the yttrium iron garnet (YIG) nanocrystal to investigate the shielding effectiveness of the composite structure. Firstly, the effect of the pyrolysis temperature on the shielding effectiveness of biochar was investigated. Secondly, biochars combined with YIG nanocrystals with different contents and shielding effectiveness of the composites were investigated. The electromagnetic effectiveness of the samples was investigated within the X band (8–12 GHz). The findings indicate that biochar demonstrates enhanced absorption properties with elevated pyrolysis temperatures. Biochars demonstrated an approximate 40 dB shielding effectiveness, while YIG exhibited approximately 7 dB, corresponding to absorption at 8 GHz. However, the combination of biochar and YIG exhibited exceptional absorption, reaching 67.12 dB at 8 GHz
Comparison of postoperative balance and function between primary and revision total knee arthroplasty
No full textObjective: This study aimed to compare postural balance, functional performance, and patient-reported outcomes between primary total knee arthroplasty (pTKA) and revision total knee arthroplasty (rTKA) patients. Methods: A cross-sectional analysis was conducted on 37 patients (57 knees: 30 pTKA, 27 rTKA) who were at least one-year post-surgery. Balance was evaluated using the Biodex Biosway system (postural stability, limits of stability, sensory interaction), while functional mobility was assessed with the 2-Minute Walk Test (2MWT), Timed Up and Go Test (TUGT), and 30-Second Chair Stand Test (30CST). Patient-reported outcomes included the Hospital for Special Surgery knee scale, Lower Extremity Functional Scale, Activities-specific Balance Confidence Scale, and SF-12 health survey. The Benjamini-Hochberg correction was applied for multiple comparisons. Results: The rTKA group was significantly older compared to the pTKA group (p < 0.01). The rTKA group demonstrated significantly worse postural stability with higher scores on the Anteroposterior Stability Index (p = 0.01) and Overall Stability Index (p = 0.007). In functional performance, the pTKA group significantly outperformed the rTKA group on the 2MWT (p = 0.003), TUGT (p = 0.03), and 30CST (p = 0.03). However, there were no significant differences in most patient-reported outcomes, except for a higher SF-12 Mental Component score in the rTKA group (p = 0.036). Conclusions: rTKA patients exhibit significantly worse objective postural balance and functional performance compared to pTKA patients, despite achieving similar pain and functional scale scores. These findings, while influenced by the rTKA group's older age, highlight the need for tailored rehabilitation protocols that specifically address balance deficits and proprioception in this patient population

No full textCompressibility behavior of colemanite added bentonite under short and long-term high temperature
No full textThe present study focuses on the one-dimensional consolidation of bentonite mixtures under high temperatures. To further investigate the volume deformation behavior of bentonite mixtures under different thermal conditions, consolidation tests were performed on the samples exposed to both short-term and long-term high temperatures. To investigate the long-term temperature effects, the samples were placed in thermal pools for six months and one year before being tested in a temperature-controlled oedometer test system. Furthermore, the influence of colemanite on the high-temperature consolidation behavior of bentonite was examined. The outcomes of this research provide valuable insights for addressing geotechnical engineering problems concerning consolidation under high temperatures. Notably, changes in temperature and exposure time impact the final settlement of the soil. Findings revealed that high temperatures led to increased compressive strain in bentonite while decreasing its unloading deformation. However, high-temperature exposure had a positive effect on the compressive strain of bentonite. Moreover, the addition of colemanite positively impacted the consolidation characteristics of bentonite under various thermal scenarios. The results have shown that the 10 % and 20 % colemanite showed different effects on the volumetric deformation of bentonite
Investigation of domestic gas fired boiler's condensation area via multiphase CFD and infrared thermography
No full textThis study presents a comparative investigation into condensate water formation in a domestic gas-fired condensing boiler under varying thermal loads. By integrating experimental methods with computational fluid dynamics (CFD), the research assesses condensation and latent heat recovery at input capacities of 6, 12, 18, and 24 kW. This research stands out due to its use of infrared thermography to capture the temperature distributions on the condensation region of the combi boiler. These temperature distributions are then used as boundary conditions in a transient, three-dimensional CFD model. This approach yields a more accurate representation of phase-change dynamics in a multiphase flow environment. The results indicate that while the total mass of condensation increases with higher loads due to greater water vapor generation, the specific condensation yield per kilowatt is significantly improved at lower loads and reaches a peak value of 4.38 × 10−5 kg/s·kW at 6 kW, as thermal imaging revealed more uniform and lower surface temperatures during partial-load operation. These findings illustrate that optimal conditions for enhanced latent heat recovery are present at reduced loads. The CFD model demonstrated a strong alignment with experimental results, exhibiting a maximum deviation of 10.3 %, thereby validating its reliability for phase-change predictions. Notably, this work uniquely focuses on the condensation zone and introduces thermal imaging as an innovative source of boundary conditions. The outcomes provide valuable insights for improving boiler performance under real-world modulating conditions and underscore the importance of part-load operation for enhancing both energy efficiency and emission reduction in residential heating systems

The aim of this study is to make the lessons more interesting and interactive by presenting mythologicalstories with metaverse technology in geography teaching; to provide students with a deeper understanding ofgeography topics. In addition, it aims to develop students' creative thinking, problem solving, active use ofchanging and constantly developing technology in lessons and cultural awareness skills. Through this approach, itwill be possible for students to deepen their academic gains, develop their creativity and problem solving skills,and strengthen their digital literacy. Document analysis and metaverse methods were utilized in the study. In thestudy, the literature on geography education, mythology and metaverse was examined. In addition, learning areasthat can be associated with mythological elements in the secondary geography curriculum were identified. For thestory example to be created in the metadiscourse environment, the topic of plants in the 10th grade "NaturalSystems" unit was selected and in this context, the story of Daphne and Apollo in Greek mythology was discussed.In the story, especially the motif of turning into a laurel tree was associated with geography in terms of symbolizingthe nature-human relationship and adapted to the learning context. During the design process, the characters andspace elements of the story were modeled in three dimensions using Blender software. Realistic scene layouts thatcould increase students' interest were created and the mythological narrative was animated scene by scene. Thesevisual elements were then transferred to Spatial.IO software, a metaverse-based learning environment, and ascenario was designed in which students could interact with their avatars. In this way, students will be able toexperience the story in a virtual world instead of just reading it, explore the spatial context in which the eventstake place in three dimensions and learn geographical elements in a more permanent way. The design approachrevealed by the research shows that metaverse-supported mythological content can increase students' interest ingeography lessons, make learning more memorable, and make significant contributions to understanding therelationship between space and mythology. In addition, this approach can enable students to concretize abstractgeographical concepts, connect with cultural heritage, and make the course process more fun and interactive. Inthis way, skills such as critical thinking, creativity and communication can be supported. The study directlyoverlaps with the goals of "Establishing an Ecosystem for the Development of Digital Content and Skills" and"Producing Content for the Development of Digital Skills and Conducting Teacher Trainings" emphasized in theMinistry of National Education's 2023 Education Vision. At the same time, it provides an example that cancontribute to the student-centered, innovative and digital-oriented approach of the The Türkiye Century EducationModel. In this respect, the study strengthens the interdisciplinary dimension of geography courses and makes aunique contribution to the digital learning ecosystem required by the age. As a result, transferring mythologicalstories to the metaverse environment can bring an innovative method to geography teaching. This method canenrich the learning experience by supporting both cognitive and cultural development of students and at the sametime provide a framework that is compatible with the transformation goals of the digital age in education.</p
