    Bir Diş İmplant Protezinde Sıcaklık ve Gerilme Dağılımının İncelenmesi

    Aygün, Cemalettin; Taşdemir, İkram

    Günümüzde, implant uygulamalarının artan başarı oranları ve kullanım sıklığı, diş hekimliği alanında dişsel implantlara çekmiştir. Bu çalışmada bir diş implant protezindeki sıcaklık ve gerilim dağılımı sonlu elemanlar yöntemini kullanan ticari yazılımı olan Ansys paket programı kullanılarak, üç boyutlu olarak modellenmiştir. Modele 100N’luk yük ve sırasıyla 45o C ve 10o C sıcaklık uygulanarak implant protezinde meydana gelen değişimler incelenmiştir. Sıcaklık giriş koşulu, en yüksek sıcaklık (45o C) için ocaktan yeni alınmış yiyecek/içecek ve en düşük sıcaklık (10o C) için ise buzdolabından yeni çıkarılmış içecek sıcaklığı olarak kabul edilmiştir. Yapılan analizler (Fluid Flow) sonucunda 45o C ve 10o C sıcaklıkta implant protezinin diş köküne ısıyı iletmediği görülmüştür. 100N ’luk yük altında ise von Mises gerilim dağılımı ve toplam deformasyon analiz sonucunda, çekme ve basma dayanımının iyi olduğu (48.17 MPa), uygulanan yükün büyük bir kısmının ise suni diş kronu tarafından karşılandığı belirlenmiştir. Diş geometrisinden yapısından dolayı uygulanan çiğneme kuvveti, tüm eksenlerde homojen olmayan gerilme dağılımına sebep olmaktadır. Bu durum biyouyumluluğun yanında mekanik uyumluluğunda büyük önem arz ettiğini ortaya koymaktadır. Suni diş kronu ve diş kökün de sıklıkla kullanılan titanyum alaşımları (Ti-6Al-4V) koruyucu oksit tabaka oluşturmasıyla birlikte kemik yapısında da farklılaşmaya sebebiyet vermektedir. Özellikle osteoporoz ve menopoz dönemlerinde kemik hacminde oluşan kayıplar ve kemik erimesi hastalıkları da göz önüne alındığında, implant-kemik arayüzünde sorun oluşabileceği muhtemeldir.

    Reclaiming Agency through Fashion: Postcolonial Identities and Colonial Legacies in V.S. Naipaul's A Bend in the River*

    Yalcin, Elif Guvendi

    Fashion plays a critical role in human cultures, acting as a canvas for expressing cultural identity, social status, and individual creativity. Its multifaceted nature allows for varied interpretations, much like a complex language. Theorists are increasingly acknowledging this, recognizing how clothing communicates non-verbally, subtly conveying social messages and influencing interactions. This aspect is particularly evident in literature, where characters' clothing choices are deeply connected with their development and contribute significantly to the narrative's emotional richness. Fashion, therefore, extends beyond its aesthetic function, emerging as a dynamic tool for expressing post-colonial identities and challenging the lingering influence of colonialism. In cultures marked by colonial and imperial histories, fashion becomes an emblem of identity, offering a means to reclaim and redefine cultural narratives. It is through fashion choices that individuals express their cultural identity, challenge norms imposed by others, and resist the erasure of their heritage. It becomes a tool for empowerment and self-representation, allowing marginal communities to reclaim agency over their own narratives. While colonialism may have ended, the legacy of colonialism has left lasting impacts on economies, social structures, and cultural perceptions. The Western nations continue actively participating in imperial activities to protect their wealth and power by exploiting other countries economically. The internalization of colonial values has deeply influenced the perception of fashion among people from once colonized countries. The cultural values of these countries are often deemed "uncivilized" in contrast to the "superior," "civilized," and "rational" standards of the colonizers. As a result, Western fashion trends, representative of the colonizers' ideals, permeate the local markets and overshadow indigenous styles. Fashion is used as a means of signifying power, class, and status, and European modes of dress are seen as a symbol of sophistication and modernity. Drawing upon the broader theoretical framework of postcolonialism, this paper critically analyses V.S. Naipaul's work A Bend in the River (1979) to demonstrate how fashion choices create identities to continue colonial legacies.

    The New Conformable Methods to Solve Conformable Time- Fractional Generalized Burgers Equation with Proportional Delay

    Anaç, Halil; Avcı, Halil Hüseyin

    In this article, two novel methods called conformable q-Mohand homotopy analysis transform method (Cq-MHATM) and conformable Mohand Adomian decomposition method (CMADM) are utilized to examine the novel numerical solutions for nonlinear conformable time-fractional generalized Burgers equation with proportional delay. The first of the two new methods suggested, Cq- MHATM, is a hybrid method that combines q-homotopy analysis transform method and Mohand transform in the sense of comformable derivative. The other method, CMADM is also a hybrid method that combines Adomian decomposition method and Mohand transform in the sense of comformable derivative. The computer simulations were worked out to prove that the suggested methods work and are trusted.

    The effect of country image on behavioral intentions: parallel mediation effects of product and service quality

    Sevim, Nurdan; Hall, Elif Eroglu; Izmir, Onur

    Consumers use the country image as not only heuristics to predict the quality of the products but also as a symbol of the self by which they affiliate themselves with certain groups and differentiate from others. This study intents to understand the effects of COI on product and service quality perceptions and a set of behavioral intentions through a holistic perspective in the automobile industry. Moreover, as a complementary element, some insights into the conceptualization and the measurement of the country image are meant to be gained. The findings of this study verify the assertions in the current literature on the two-dimensional country image construct, which consists of cognition and affect. The cognition-oriented country image scales threaten the validity of studies conducted in this area because the results obtained with cognition-oriented scales are inadvertently attributed to the (general) country image construct consisting of both cognitive and affective elements. In line with the service dominant logic, it is identified that a holistic approach is required predicting the effects of the country image on quality perceptions. Even in such a pure product category as automobiles, strong associations were identified between country image and perceived service quality. Therefore, regardless of the content of the market offering, it is important that quality must be evaluated under two separate dimensions as (physical) product quality and service quality. With the help of this twodimensional conceptualization of country image and quality perceptions, country of origin element attached to the market offering can be transformed into actual behaviors.

    Investigation of the seasonality of occupational accidents in mine operations

    Kahraman, M Mustafa; Turan, Sevda

    Mine operations might be viewed as relatively risky in terms of worker safety when compared to other industries. Every year, there are a lot of occupational accidents and near-misses at mining sites. Most of the time, data from these circumstances are recorded, but they are typically not properly utilized. Information gathered from occurrences helps researchers understand how various conditions affect accidents and their frequency. The information obtained from such investigations may provide practical advice on how to prevent happening again. For instance, there are many studies in the literature that analyze mining accidents according to their countries, yearly frequency, work areas, and types of work; however, there isn't a single study that looks at the relationship between meteorological conditions and the seasonality of the accidents. The correlations between seasonal and regional variables, such as temperature, humidity, and pressure, and occupational accidents that occurred in mines with various climatic features, chosen from two different nations, were examined in this study. The findings indicate that there is a strong relationship between the frequency of accidents and the seasons, however this relationship would be weaker if incidents were looked into on a monthly basis. In conclusion, this article demonstrates that temperature and humidity in mining operations during severe weather conditions have a significant impact on occupational accidents.

    The Predicament of In-betweenness in Denis Devlin’s “Memoirs of a Turcoman Diplomat

    Hakkıoğlu, Mümin

    Denis Devlin (1908-1959) is regarded as one of the most important representatives of Irish modernist poetry. After joining the Department of External Affairs in 1935, he spent most of his life undertaking diplomatic missions for his country in Washington, New York, Rome and London, and in 1951, he served as an accredited ambassador in Istanbul, Turkey. Devlin, as a poet-diplomat, included the codes of the countries he worked in his poems. Among them, “Memoirs of a Turcoman Diplomat” has a special place. Here, a retired diplomat, watching the city from the terrace of a hotel in Istanbul, is depicted to contemplate the profound differences between the Ottoman State he served in the past and Turkey which turned its face to the West after the proclamation of the republic. On the one hand, he is the man of a civilisation against which Europe historically positioned itself, and on the other, the citizen of the republic which has set its target to reach the level of contemporary civilisation and implemented a series of reforms for that cause. He is stuck in between the world of the old, which was Islamic, multi-ethnic, and mighty and the world of the present, which is secular, monolithic, and shaped by the new ideology. The poem conspicuously, to a large extent, focuses on the tension caused by this stuckness and emphasises the state of in-betweenness of the poetic persona. The aim of this study is to explore how the diplomat in the poem, as an intellectual of his society and a representative of the old regime, meets the tension stemmed from the sharp conversion of his country, and to examine the dilemmas he has experienced due to his crisis of belonging through the concept of “in-betweenness”. It also discusses if there is a possibility of another space which can create a healing alternative for the poetic persona away from all tensions and problems. Furthermore, it questions how this poem reflects the historical, cultural and political similarities between the Republic of Turkey and the Republic of Ireland, and asserts that the Turkish diplomat of the poem is partly the poet-diplomat Denis Devlin himself.

    Ödemiş, Murat

    Information technologies are rapidly showing their effect in the tourism industry as well as in every field. Online platforms have become a significant channel where consumers frequently share their consumption experiences and take them into account in their destination preferences. If managed effectively by destinations, it can become an effective tool in shaping consumer perception and brand loyalty. According to this, it is aimed to detect whether perceived value (PV) has a mediating role in the influence of online consumer reviews (OCRs) on destination brand loyalty (DBL) in the research. The sample of the research comprises of 315 attendants who visit Istanbul for touristic purposes. Research data were collected with the survey data gathering tool. After testing the data obtained from the attendants in terms of normality, reliability and construct validity, the relationships between the variables were investigated by correlation analysis. In the last stage, the hypotheses of the research were tested with simple linear regression and hierarchical regression analysis. Consequently, the basis hypothesis (H4) of the research, "the mediating role of PV in the influence of OCRs on DBL" were accepted with full mediation influence, and also accepted other hypotheses of research (H1, H2 and H3).

    Aydin, Aydanur; Gürsoy, Ayla; Candas Altinbas, Bahar; Cilingir, Dilek; Bulut, Enes; Ertürk Yavuz, Melek

    Background: Human and technology factors in healthcare can lead to errors that threaten human life. A strong patient safety culture in hospitals may be linked to better patient outcomes. Because of the potential for mistakes in surgical departments, surgical nurses are critical to establishing and maintaining a patient safety culture. Aim: The aim of this study was to explore the patient safety culture perceptions of surgical nurses. Methods: This descriptive study was performed with 206 nurses working in the surgical clinics and operating rooms of 1 university hospital, 2 public hospitals, and 1 private hospital. A “Questionnaire” and the “Hospital Survey on Patient Safety Culture” were used for data collection. The data were analyzed using mean, number, and percentage values, 1-way analysis of variance, Tukey Honestly Significant Difference (HSD), and chi-square tests. Results: The study revealed that surgical nurses’ patient safety culture perception was at a medium level. The highest mean rate of positive responses in The Hospital Survey on Patient Safety Culture came from “Teamwork within units” and the lowest mean rate of positive answers came from the “Non-punitive response to errors” subdimension. In addition, 85.7% of the surgical nurses did not report any errors in the previous 1 year, and nurses who had been working for ≥11 years submitted more error reports (P = .001). Conclusion: Nurses’ patient safety culture perception was at a medium level. Recommendations for improving patient safety culture should include on-the-job training programs and improvements in employees’ working conditions.

    Numerous variables can affect performance before the competition. Nevertheless, it could be a subject of curiosity to find out whether a warm-up strategy has a more positive effect on the power performance of kickboxers. The purpose of this study is to evaluate the effect of different specific warm-up protocols and time of day on optimum power performance in kickboxers. Ten volunteer males performed three different warm-up routines in random order. The warm-up protocols consisted of only 20 min for each group. The groups with low-intensity aerobic running (NSWU) and specific warm-ups (SWU-20m) performed 20-min protocols. The other group followed 10 minutes of jogging and 10 minutes of specific warm-up (SWU-10m). All groups followed the warm-up randomly at two different periods of the day (i.e. morning: 09:00-10:00 and evening: 16:00-17:00) on non-consecutive days. A statistically significant difference was found between the groups in terms of Mean Propulsion (W) (F=3.518; p2=0.036). There was a statistically significant difference in Mean propulsive Power (W) between NSWU and SWU-10m (p3= 0.0007) in addition there was also a statistically significant difference in SWU-10m and SWU-20m (p3= 0.0106) and, NSWU and SWU-20m (p3= 0.415) protocols. In conclusion, mean propulsion (W) performance showed diurnal variation, and performances of the kickboxers’ can be affected more positively in the evening hours, especially after SWU protocols.

    LEARNING STYLES OF TALENTED PRE- SERVICE TEACHERS

    Türker, Ustun; Bostanci, Ozgur

    The learning styles of students vary both among individuals and across different disciplines they choose to study. In higher education, academic discipline appears to be a key factor influencing students'distinctive learning styles. This study, which aims to determine the dominant learning styles and models of talented pre-service teachers, was designed with the survey model. The study group research consisted of 1019 volunteer pre-service teachers who continued their education in Physical Education and Sports, Music, and Arts & Craft Teaching departments. In the study, the VARK Learning Style Inventory was used as a data collection tool; students were asked to answer questions in a digital environment through Google Forms. According to the research results, kinesthetic style is the dominant learning preference for pre -service teachers in the visual arts and sports sciences, and both kinesthetic and aural styles are the dominant learning preferences for pre-service teachers in music education. Although talented pre-service teachers tend to learn predominantly kinesthetic and aural styles when evaluated, 61.2% of pre-service teachers prefer to learn with a Multiple Learning Model, which covers the entire instructional diversity, rather than sticking to just one learning style.
