Evolution of consumption into display, a bibliometric perspective on “consumer society”
No full textKüreselleşmeyle birlikte değişen yaşam tarzları, tüketim topluluğu olarak adlandırılan yeni modern toplulukların oluşmasına zemin hazırlamıştır. Tüketimin temel bir ihtiyacı karşılamasından ziyade gösterişe, statüye evrilmesi, toplumlarda yeni bir tüketim anlayışını oluşturmuştur. Bu çalışmada son zamanlarda özellikle sosyal bilimlerde kaynakların tükenmesi nedeniyle sıkça tartışılan bir konu olan “tüketim toplumu” kavramı araştırılmıştır. Tüketim toplumu kavramına yönelik gerçekleştirilen çalışmalar özelinde bibliyometrik bir literatür araştırmasının haritasını ortaya koymak hedeflenmiştir. Bu doğrultuda Web of Science veri tabanında tüketim toplumu ile ilgili ulaşılan 679 çalışma belirli kıstaslar altında sistematik literatür çerçevesinde analiz edilmiştir. Tüketim toplumu ile ilgili Kasım 2024 tarihine kadar olan çalışmalar değerlendirilmiştir. Gelecekte yapılacak olan çalışmalar için alt yapının oluşturulması amacıyla sistemli bir literatür çalışmasının özeti sunulmuştur.The changing lifestyles with globalization have paved the way for the formation of new modern communities called consumer societies. The evolution of consumption into ostentation and status rather than meeting a basic need has created a new understanding of consumption in societies. In this study, the concept of “consumer society”, which has been a frequently discussed topic recently, especially in social sciences due to the depletion of resources, has been investigated. It is aimed to create a systematic literature research map specifically for the studies carried out on the concept of consumer society. In this direction, 679 studies reached in the Web of Science database on consumer society were analyzed within the framework of systematic literature under certain criteria. Studies on consumer society up to November 2024 were evaluated. A summary of a systematic literature study is presented in order to create the infrastructure for future studies
Urban air PCDD/Fs: Concentration, temporal change, cancer risk and source identification
No full textPoliklorlu dibenzo-p-dioksinler (PCDD'ler) ve poliklorlu dibenzofuranlar (PCDF'ler), uzun çevresel yarı ömürleri ve yağlı dokularda birikme eğilimleri nedeniyle insan sağlığı için ciddi riskler oluşturan toksik, kalıcı organik kirleticilerdir. Bu bileşikleri çevredeki izlemek için yaygın olarak hem aktif hem de pasif örnekleme yöntemleri kullanılır. Bu çalışma, Haziran 2022 ile Haziran 2023 tarihleri arasında Bursa kentinde, pasif örnekleme kullanarak PCDD/F bileşiklerinin atmosferik konsantrasyonlarındaki zamansal değişimi araştırmak amacıyla yürütülmüştür. Bursa’da pasif örnekleyici kullanılarak yapılan ve tüm yılı kapsayan ilk PCDD/F çalışması olan bu araştırmada, her bir örnekleme ortalama bir ay sürmüş ve üç adet pasif hava örnekleyicisi (PHÖ) kullanılmıştır. PCDD/F'lerin mevsimsel ortalama konsantrasyonları ilkbaharda 324.66 ± 51.87 fg/m³, yazın 234.79 ± 57.57 fg/m³, sonbaharda 363.07 ± 77.99 fg/m³ ve kışın 479.88 ± 73.20 fg/m³ olarak belirlenirken, yıllık ortalama konsantrasyon 341.50 ± 108.27 fg/m³ olarak bulundu. Ölçüm süresi boyunca tespit edilen baskın konjenerler OCDD, OCDF, 1,2,3,4,6,7,8-HpCDF ve 1,2,3,4,6,7,8-HpCDD idi. Dünyanın dört bir yanındaki diğer kentsel ve endüstriyel alanlarda yürütülen benzer çalışmalarla karşılaştırıldığında, ölçülen konsantrasyonların tutarlı ve karşılaştırılabilir aralıklarda olduğu bulundu. Konsantrasyon ölçümlerine ek olarak, konjener profilleri, potansiyel kaynaklar, mevsimsel değişimler, sağlık riskleri ve atmosferik taşınım davranışını değerlendirmek için kapsamlı analizler yürütülmüştür. PCDD/F'lerin atmosferik taşınım özelliklerini değerlendirmek için Clausius-Clapeyron denklemi uygulanmıştır. Ayrıca, PCDD/F'lerin potansiyel kaynaklarını belirlemek için Temel Bileşen Analizi (PCA) kullanılmıştır. Sonuçlar, araç emisyonlarının, konut ısıtma yakıtlarının ve organize sanayi bölgelerindeki yanma faaliyetlerinin çalışma alanındaki PCDD/F seviyelerine birincil katkıda bulunan faktörler olduğunu göstermiştir. Sonuç olarak, bu çalışma kentsel hava kirliliği ve PCDD/F emisyonları hakkında değerli bilgiler sağlamakta ve benzer kentsel ortamlarda hava kalitesinin izlenmesi ve yönetimini amaçlayan gelecekteki çabalar için güçlü bir temel sunmaktadır.Polychlorinated dibenzo-p-dioxins (PCDDs) and polychlorinated dibenzofurans (PCDFs) are toxic, persistent organic pollutants that pose serious risks to human health due to their long environmental half-lives and their tendency to bioaccumulate in fatty tissues. Both active and passive sampling methods are commonly employed to monitor these compounds in the environment. This study was conducted in an urban area of Bursa, Turkey, between June 2022 and June 2023, with the aim of investigating the temporal variation in atmospheric concentrations of PCDD/F compounds using passive sampling. As the first year-round study in Bursa to utilize passive air samplers (PAS) for PCDD/F monitoring, the research involved monthly sampling intervals using three PAS units. The seasonal average concentrations of PCDD/Fs were determined to be 324.66 ± 51.87 fg/m³ in spring, 234.79 ± 57.57 fg/m³ in summer, 363.07 ± 77.99 fg/m³ in autumn, and 479.88 ± 73.20 fg/m³ in winter, with an annual average concentration of 341.50 ± 108.27 fg/m³. The dominant congeners detected throughout the measurement period were OCDD, OCDF, 1,2,3,4,6,7,8-HpCDF, and 1,2,3,4,6,7,8-HpCDD. When compared to similar studies conducted in other urban and industrial areas around the world, the measured concentrations were found to be consistent and within comparable ranges. In addition to concentration measurements, comprehensive analyses were conducted to evaluate congener profiles, potential sources, seasonal variations, health risks, and atmospheric transport behavior. The Clausius-Clapeyron equation was applied to assess the atmospheric transport characteristics of PCDD/Fs. Furthermore, Principal Component Analysis (PCA) was used to identify potential sources of PCDD/Fs. The results indicated that vehicular emissions, residential heating fuels, and combustion activities in organized industrial zones were the primary contributors to PCDD/F levels in the study area. In conclusion, this study provides valuable insights into urban air pollution and PCDD/F emissions, offering a strong foundation for future efforts aimed at air quality monitoring and management in similar urban environments
The validity and reliability study of the turkish version of the health behavior scale for cancer patients
No full textAIM: The aim of the study was to conduct a validity and reliability study of the Health Behavior Scale for Cancer Patients and to adapt the scale to the Turkish language and culture. METHODS: The research is a methodological study. The sample consisted of a total of 440 cancer patients who came to the outpatient chemotherapy unit and oncology outpatient clinic of a university hospital and followed the social media accounts of a cancer-related association. Patients aged 18 and over and with at least a primary school education were included in the study. Data were collected between January and December 2022 with the Descriptive Characteristics Form and The Health Behavior Scale for Cancer Patients. For the validity analysis, language equivalence, content validity, exploratory and confirmatory factor analyses were performed. For the reliability, internal consistency, item-total score correlation, and test-retest were performed. RESULTS: According to the exploratory factor analysis, a two-factor structure was obtained and confirmed by confirmatory factor analysis. According to the factor loadings (0.60-0.87), total variance explained (61.575), and fit indices, the construct validity of the scale was found to be sufficient. In the reliability analyses, Cronbach's alpha internal consistency coefficient (0.85) was found to be highly reliable. It was determined that there was a very strong relationship between the pre-test and the post-test (r = 0.87, p < .001). CONCLUSION: The Health Behavior Scale for Cancer Patients has been revealed to be a valid and reliable measurement tool suitable for Turkish culture. Using this scale, cancer patients' adherence to medical health services and individual protective health behaviors can be determined

Design: Single blind randomized controlled study. Methods: The sample of the study consisted of 48 experimental and 48 control groups, totaling 96 nursing students. The intervention group received the "Artificial Intelligence Integrated Nursing Process" training program. The control group only received the standard nursing process education. The data collection instruments were administered before the training and after the training. Chi-square analysis was used to compare variables, independent samples t-tests were used for comparisons between groups, and paired t-tests were used for within-group comparisons. Results: In the post-education measurements, students in the intervention group demonstrated a significantly lower average total problem solving inventory score compared to those in the control group, indicating an improvement in problem-solving skills. The intervention group showed an increase in positive attitudes towards artificial intelligence compared to the control group and a decrease in negative attitudes. In the intervention group, students showed a significant increase in their nursing process competency levels and satisfaction levels after the training, whereas no significant change was observed in the control group. Conclusion: This study demonstrates that the training provided on the use of ChatGPT in the nursing process positively impacted nursing students' problem-solving skills, attitudes towards artificial intelligence, competencies related to the nursing process, and levels of satisfaction
Interpretation and analysis of scattering in steel fiber alignment in concrete: The h alpha decomposition method using fully polarized b-scan ground penetrating radar (gpr) image data
No full textThe brittle behavior of concrete often necessitates fiber reinforcement to improve load distribution and crack resistance. This study examines fiber orientation in steel fiber-reinforced concrete, achieved by strategically aligning fibers within the fresh composite. B-scan Ground Penetrating Radar (GPR) with full polarimetric imaging is utilized for non-destructive assessment of fiber alignment in the concrete matrix. Using two horn antennas, measurements are taken at two cm intervals along a 120 cm synthetic aperture at 101 different locations in the 2-6 GHz frequency band in horizontal-horizontal (HH), vertical-vertical (VV), horizontal-vertical (HV), and vertical-horizontal (VH) polarizations. These measurements, made at frequencies between 2 and 6 GHz across a range of polarizations, enabled two-dimensional imaging using both H-alpha polarimetric decomposition and raw data images. These imaging methods are used in combination with H-alpha classification surfaces separated into different scattering regions and raw S22 and S21 2D images to obtain the expected results. Results indicate that concrete samples with random, horizontal, and vertical fiber orientations exhibit distinct scattering patterns, enabling accurate identification of internal fiber configurations. The scattering analysis confirmed the precision of alignment determination, demonstrating a reliable, non-destructive method for evaluating fiber orientation in reinforced concrete. This approach holds substantial promise for quality assurance and performance assessment in fiber-reinforced concrete production
Development of sandwich structures with different composite surface plates and investigation of their behavior under instant impact loads
No full textKompozit malzemeler, üstün mekanik ve fiziksel özellikleri sayesinde havacılık, mimari, otomotiv ve savunma sanayii gibi pek çok sektörde geniş bir uygulama alanı bulmaktadır. Çeşitli elyaflarla takviye edilen bu malzemeler, geleneksel malzemelere kıyasla daha üstün performans göstermekte ve bu nedenle sandviç yapıların yüzey plakaları için ideal bir tercih oluşturmaktadır. Bu çalışmada, alüminyumdan üretilmiş çift yönlü oluklu şerit çekirdek yapılar tasarlanmış ve bu yapılar, noktasal darbelere karşı dayanımı artırmak amacıyla kompozit plakalarla sandviç yapı haline getirilmiştir. Yüzey plakaları, cam, karbon ve kevlar elyaf kumaşların vakum infüzyon yöntemiyle epoksi reçine emdirilmesi yoluyla üretilmiştir. Farklı fiber türlerinden üretilmiş yüzey plakalarına sahip sandviç yapılar, dinamik üç nokta eğilme testine ve sivri uçlu bir darbe başlığı kullanılarak noktasal delme testlerine tabi tutulmuştur. Bu testlerde her bir yapının delinme direnci ve enerji sönümleme kapasitesi analiz edilmiştir. Test sırasında çekirdek yapıda oluşan burkulma davranışları, yüzey plakalarının rijitliği ve elastisite özellikleriyle yakından ilişkilendirilmiştir. Elde edilen sonuçlar geliştirilen sandviç yapıların batarya kutuları ve yakıt tankerleri gibi noktasal darbelere karşı dayanıklı malzemelere ihtiyaç duyulan uygulamalarda potansiyel bir alternatif olarak kullanılabileceğini ortaya koymaktadır.Composite materials find a wide range of applications in many sectors such as aviation, architecture, automotive and defense industry due to their superior mechanical and physical properties. These materials, reinforced with various fibers, show superior performance compared to traditional materials and therefore constitute an ideal choice for surface plates of sandwich structures. In this study, double-sided corrugated strip core structures made of aluminum were designed and these structures were made into sandwich structures with composite plates in order to increase resistance against point impacts. Surface plates were produced by impregnating glass, carbon and Kevlar fiber fabrics with epoxy resin by vacuum infusion method. Sandwich structures with surface plates made of different fiber types were subjected to dynamic three-point bending test and point puncture tests using a pointed impact head. In these tests, the puncture resistance and energy absorption capacity of each structure were analyzed. The buckling behaviors occurring in the core structure during the test were closely related to the rigidity and elasticity properties of the surface plates. The results obtained reveal that the developed sandwich structures can be used as a potential alternative in applications requiring materials resistant to point impacts, such as battery boxes and fuel tankers
The recurrence outcome with respect to treatment choices in idiopathic granulomatous mastitis: A retrospective cohort study with 10-year single-center experience
No full textBackground: This study aimed to investigate the recurrence outcome with respect to treatment choices in patients with idiopathic granulomatous mastitis (IGM). Methods: A total of 175 female patients (mean +/- SD age: 36.3 +/- 8.9 years) with histopathologically confirmed IGM were included in this retrospective cohort study. Data on patient age, presenting symptoms, treatment protocols (medical and/or surgery), the recurrence rate, recurrence-free survival (RFS) and progression-free survival (PFS) were recorded. RFS time (month) and PFS and time (month) were compared across medical treatment subgroups (antibiotic, steroid, steroid-sparing immunosuppressant). Results: The treatment protocols involved surgery plus medical treatment in 82(46.9 %) patients, medical treatment alone in 82(46.9) and surgery alone in 11(6.2 %) patients. The medical treatment included the immunosuppressive therapy (42.1 %), antibiotic therapy (29.3 %) and steroid therapy (28.7 %). Within a median 36 months of follow-up, recurrence was noted in 64(39.5 %) patients and was significantly more common in the surgery plus medical treatment group than in the medical treatment alone group (53.7 % vs. 25.0 %, p < 0.001). Overall, median (95 % CI) RFS time and PFS time were 29(21.9-36.1) months and 12(5.8-18.2) months, respectively. No significant difference was noted between medical treatment subgroups in terms of RFS time (log-rank p value: 0.176) and PFS time (log-rank p value: 0.421). Nonetheless, immunosuppressive therapy showed a non-significant tendency for longer RFS (vs. steroid therapy) and longer PFS (vs. both antibiotic and steroid therapy). Conclusions: In conclusion, this retrospective cohort study in patients with IGM revealed the association of systemic therapy, particularly the steroid-sparing immunosuppressive treatment, with favorable long-term RFS and PFS outcome.

Nutritional and inflammatory indices in gestational and pregestational diabetes: Emphasis on the controlling nutritional status (conut) score
No full textObjectiveTo comparatively evaluate the prognostic value of nutritional and inflammatory indices in gestational diabetes mellitus (GDM) and pregestational diabetes mellitus (PGDM), and to determine their association with adverse perinatal outcomes. MethodsThis retrospective study included 280 pregnant women followed at a tertiary care center between January 2020 and December 2024. Participants were categorized into three groups: GDM (n = 90), PGDM (n = 80), and healthy controls (n = 110). Nutritional status was assessed using the Controlling Nutritional Status (CONUT) and Prognostic Nutritional Index (PNI) scores. Inflammatory indices including NLR, SII, SIRI, PIV, and others were calculated. Perinatal outcomes such as preterm birth, NICU admission, and Composite Adverse Perinatal Outcomes (CAPO) were recorded. ROC analysis was used to determine the predictive power of the biomarkers. ResultsThe PGDM group demonstrated significantly higher CONUT scores and lower PNI scores compared to the other groups (p < 0.001). Among inflammatory markers, NLR, SII, SIRI, and PIV were significantly elevated in PGDM cases. ROC analyses revealed that the CONUT score had strong discriminative ability in differentiating diabetic (GDM and PGDM) from non-diabetic pregnancies (AUC = 0.787; specificity = 89.1%), while the PNI score showed limited discriminative capacity (AUC = 0.291). Inflammatory indices also demonstrated moderate predictive value, particularly among PGDM cases. Higher CONUT and inflammatory scores were associated with increased rates of preterm birth, NICU admission, and CAPO (p < 0.001). ConclusionNutritional and inflammatory disturbances are more prominent in PGDM than in GDM. The CONUT score and selected inflammatory indices may serve as valuable tools for early risk stratification in diabetic pregnancies. Integration of these parameters into clinical decision-making may improve perinatal outcomes, particularly in high-risk groups such as PGDM
