ÇOCUK İSTİSMARINI KONU ALAN ULUSLARARASI KAMU SPOTU REKLAMLARI ÜZERİNE GÖSTERGEBİLİMSEL BİR İNCELEME
No full textThe aim of the study is to reveal how children are represented in international public service adverts on child abuse and what messages are given through these representations. In this context, the study seeks answers to the questions such as ‘How are children represented in international public service adverts on child abuse?’ and ‘What messages are given through these representations?’. In the study, the website of the ‘Ads of the World’ organisation was selected as the sample. A total of 11 public service adverts from the relevant website were included in the study through purposive sampling. The selected public service adverts were analysed within the framework of Charles Morris' semiotics concepts of syntax, semantics and pragmatics. As a result of the study, it was determined that children were represented as passive subjects with the descriptions of vulnerable, sensitive, victim of abuse, innocent, pitiful, helpless. The messages given are that children are easy prey for abusers, family and society should be sensitive and conscious against abuse, and various objects such as belts should not be used to scare and abuse children. In addition, the messages given are that children can be abused by people of all ages, groups and positions, that the authorities should be informed in case of abuse, that children exposed to abuse are prone to crime, that sexual abuse against children is usually hidden, and that abuse should not be kept silent.Çalışmanın amacı çocuk istismarını konu alan uluslararası kamu spotu reklamlarında çocukların nasıl temsil edildiği, bu temsillerle hangi mesajların verildiğini ortaya koymaktadır. Bu bağlamda çalışmada “Çocuk istismarını konu alan uluslararası kamu spotu reklamlarında çocuklar nasıl temsil edilmektedir?”, “Bu temsillerle hangi mesajlar verilmektedir?” şeklindeki soruların yanıtı aranmaktadır. Çalışmada örneklem seçiminde “Ads of the World” organizasyonuna ait olan internet sitesi seçilmiştir. İlgili siteden toplam 11 kamu spotu reklamı amaçlı örneklem yoluyla çalışma kapsamına alınmıştır. Seçilen kamu spotu reklamları Charles Morris’in göstergebilim anlayışını oluşturan sözdizim, anlambilim ve edimbilim kavramları çerçevesinde ele alınmıştır. Çalışma sonucunda çocukların savunmasız, hassas, istismar mağduru, masum, acınası, çaresiz tanımlamalarıyla pasif özneler şeklinde temsil edildiği tespit edilmiştir. Verilen mesajlar çocukların istismarcılar için kolay avlar olduğu, istismara karşı aile ve toplumun duyarlı ve bilinçli olmaları, kemer gibi çeşitli nesnelerin çocuğu korkutmak ve istismar için kullanılmaması gerektiği şeklindedir. Ayrıca her yaş, grup ve konumda kişiler tarafından çocukların istismar edilebileceği, istismar durumunda yetkililere bilgi verilmesi, istismara maruz kalan çocukların suça meyilli olduğu, çocuğa yönelik cinsel istismarın genellikle gizli kaldığı, istismara sessiz kalınmaması verilen mesajlar arasındadır
Comparison of the performance of classical and quantum machine-learning methods on the detection of sugar beet Cercospora leaf disease
No full textImage processing and machine-learning (ML) techniques are essential for the detection of diseases and pests in plants. This study explored the application of quantum ML (QML) algorithms for the early detection of Cercospora beticola leaf disease in sugar beet, which causes significant impact on global sugar production. Using a dataset of 1065 images (739 diseased and 326 healthy), we extracted 70 ML statistical features, including 10 from the grey-level co-occurrence matrix (GLCM) and 60 colour-related features. Performance evaluations of classical ML algorithms, such as random forest (RF; 91.95% accuracy) and extreme gradient boosting (91.95% accuracy), demonstrated strong results compared to quantum approaches. Notably, the quantum support vector classifier (QSVC) achieved an accuracy of 85% with perfect recall of 1.00, while the variational quantum classifier (VQC) recorded an accuracy of 88.73%. Dimensionality reduction via principal component analysis reduced features from 70 to 5, enabling effective classification with competitive results: ML (RF) 91.41%, VQC with limited-memory Broyden-Fletcher-Goldfarb-Shanno with box constraints (L_BFGS_B) 88.73% and QSVC 85%. These findings highlight the potential of QML algorithms in improving agricultural disease identification and aiding in the advancement of more efficient, sustainable farming techniques
Heat Transfer Increase Research According to Using Different Combined Jet Flow Channel Design and Nanofluids
No full textThis study focused on the numerical investigation of heat transfer from various shaped copper plate surfaces exposed to a constant heat flux of 1000 W/m(2). The analysis employed a combination of cross-flow and impinging jet flows. The numerical simulations were carried out by solving the energy and Navier-Stokes equations using the Ansys-Fluent computer program with the k-epsilon turbulence model. To guide the combined jet flow towards the heated surfaces in the channel, horizontal fins with 30 degrees and 60 degrees angles were placed in the channel. The channel height (H) was set at 4 times the diameter (D), and the fin distance from the jet inlet (N) was equal to D. Different fin lengths of D, 1.166D, and 1.333D (K) were utilized in the channels. The study considered three types of fluids: water, 2% CuO-Water, and 0.02% GO-Water nanofluids. The upper and lower surfaces of the channel and the fin were assumed to be adiabatic, and the Reynolds number of the flow ranged from 5000 to 15000. The results of this work were compared with experimental studies from the literature, and good agreement was found between them. Unlike previous studies, this research explored the effects of fin lengths and fin angles on heat transfer from differently shaped surfaces and the flow structures created by the fins in the channels, using GO-Water and CuO-Water nanofluids. The results were presented in terms of the mean Nusselt number variations for each model surface. Additionally, velocity and temperature contour distributions of the combined jet flow along the channel for CuO-Water nanofluid were analyzed. Performance Evaluation Coefficient (PEC) values, along with average Nusselt number (Nu(m)) and surface temperature (T-m) values, were assessed at different Reynolds numbers for all three patterned surfaces in the channels. At Re = 5000 and K = D, there were significant increases in Nu(m) values for cube, roofed, and square hollow model surfaces when using a 60 degrees fin and GO-Water nanofluid compared to channels with water flow and no fins
Therapeutic Potential of Propolis and Royal Jelly in Encephalitozoon Intestinalis Infection: An in Vitro Study
No full textPurposeEncephalitozoon intestinalis is an obligate intracellular microsporidian fungus that causes severe gastrointestinal infections, particularly in immunocompromised individuals. Propolis (PROP), a resinous substance derived from bees, has antimicrobial, anti-inflammatory and antioxidant properties, while royal jelly (RJ) has immunomodulatory, antioxidant and antimicrobial activities. The aim of this study was to investigate the therapeutic potential of PROP and RJ against E. intestinalis.MethodsThe phenolic composition of PROP was analysed by high-performance liquid chromatography with diode array detection, and the chemical components of RJ were evaluated according to ISO12824 standards. The cytotoxicity of PROP and RJ on HEK-293 cells was evaluated using the XTT assay. The three highest non-cytotoxic concentrations of each sample were tested for their effects on E. intestinalis spores by qRT-PCR. Trichrome-stained photomicrographs were used to assess spore density in HEK-293 cells treated with PROP and RJ.ResultsPROP analysis revealed flavonoids such as quercetin, kaempferol, pinocembrin and galangin, as well as phenolic acids such as caffeic and cinnamic acids, known for their bioactive properties. RJ contained mainly proteins, lipids, carbohydrates and sugars, reflecting its role as a nutritionally and biologically active substance. According to the results of this first study evaluating the effect of PROP and RJ on E. intestinalis, all concentrations evaluated in the study showed a significant inhibitory effect on the growth of E. intestinalis spores compared to the control group.ConclusionIn conclusion, we believe that PROP and RJ should be considered as an alternative option in the development of antimicrosporidial drugs due to their potential medicinal and pharmaceutical properties.Sivas Cumhuriyet University [T-2021-925]; Scientific Research Project Fund of Sivas Cumhuriyet UniversityThis work is supported by the Scientific Research Project Fund of Sivas Cumhuriyet University under the project number T-2021-925

Mortality rates and risk factors associated with mortality in patients with stenotrophomonas maltophilia primary Bacteraemia and Pneumonia
No full textThis study aims to evaluate the risk factors associated with the mortality of S. maltophilia infections. Patients aged 18 years and older with S. maltophilia infection. Patients were divided into two groups primary bacteraemia and pneumonia. Of 176 S. maltophilia infections, 85 (48.2 %) were classified as bacteremia and 91 (51.8 %) as pneumonia. The mortality rate was 56 %, with no significant difference observed between the groups. Invasive mechanical ventilation, history of carbapenem use, and high Charlson Comorbidity Index (CCI) were significantly higher in the pneumonia group. In univariate analysis, higher Acute Physiology and Chronic Health Evaluation (APACHE) II score, higher Sequential Organ Failure Assessment (SOFA) score, and use of total parenteral nutrition (TPN) were identified as independent risk factors for 28-day mortality. This study demonstrates a mortality rate of 56 % in S. maltophilia infections and provides concrete data on risk factors for mortality
THE EFFECT OF MINDFUL ATTENTION ON CONSUMERS' ONLINE IMPULSIVE BUYING BEHAVIOR AND THE MODERATING ROLE OF FAMILY TYPE
No full textTüketicilerin maruz kaldığı içsel ve dışsal etkiler, satın alma davranışlarının makullüğünü farklılaştırabilir. Bu içsel etkilerden biri de dürtüdür ve online satın alma davranışlarında da etkilidir. Bilinçli farkındalığın tüketim davranışını etkilediği düşünülse de, demografik özelliklerin etkisine ilişkin kanıtlar yetersiz kalmaktadır. Bu kesitsel çalışma, MAAS (Dikkatli Farkındalık Ölçeği) puanının IBBS (Dürtüsel Satın Alma Davranışı Ölçeği) puanı üzerindeki etki derecesini ve aile tipinin bu etki üzerindeki düzenleyicilik rolünü incelemektedir. Çalışma verileri aylık geliri olan yetişkinlerden çevrimiçi anket aracılığıyla elde edilmiştir (n=459). Çalışmanın sonuçları doğrultusunda, herhangi bir demografik faktörün etkisi dikkate alınmadığında, MAAS puanı arttıkça IBBS puanının düşeceği anlaşılmaktadır. Sonuçlar aile tipinin düzenleyici rolünü açıklamaktadır. Bu bağlamda, çekirdek ailelerde yaşayan katılımcılar için MAAS skorundaki artışın IBBS skorundaki düşüş üzerinde daha anlamlı bir etkiye sahip olduğu hesaplanmıştır. Buna karşın aynı etki geniş ailelerde yaşayan katılımcılar için gözlenmemiştir.Intrinsic and extrinsic influences to which consumers are exposed can differentiate the reasonableness of their purchasing behavior. One of these intrinsic influences is impulse, which is also effective in online purchasing behavior. Although mindfulness is thought to influence consumption behavior, evidence of the effect of demographic characteristics is insufficient. This cross-sectional study examines the degree of influence of the MAAS (Mindfulness Awareness Scale) score on the IBBS (Impulsive Buying Behaviour Scale) score and the moderating role of family type on this effect. The study data were obtained from adults with monthly income through an online survey (n=459). In line with the study’s results, when the effect of any demographic factor is not considered, it is understood that the IBBS score will decrease as the MAAS score increases. The results explain the moderating role of family type. It was calculated in this context that the increase in MAAS score had a more significant effect on the decrease in IBBS score for participants living in nuclear families. However, the same effect was not observed for participants living in extended families
