Using Social Media Data To Define Boundaries of City Centers: the Case of İzmit by Foursquare
Social media has significant potential as a data source for spatial studies. The aim of this study is to determine the boundaries of the central area of Kocaeli using location-based social media data and to assess the accuracy of the method by comparing it with the central point in the existing zoning plan. In this context, the concept of city center has been emphasized and theories related to city centers have been explained. Additionally, concepts related to social media, which has recently started to be used as a data source in planning, have been explained, and examples of spatial studies conducted using this data have been presented. The district of Izmit in Kocaeli has been chosen as the study area. For the study, location-based point data was obtained using the Foursquare API. Based on literature research conducted within the Foursquare developer community, uses that are densely located in the centers have been identified, and these categories of spaces have been selected for practical application. Geographic location data belonging to these categories has been mapped, and density analyses have been conducted using GIS tools. Subsequently, spatial analyses have been overlaid and examined holistically. By superimposing the generated density maps, the boundaries of the city center have been determined. To demonstrate the representational capability of social media data in defining the central boundaries, the relationship between Foursquare data and the central point in the Izmit zoning plans has been examined through mapping and correlation analysis
Does the Neutrophil-To Ratio Affect Survival in Multiple Myeloma? a Single-Center Experience
Objective: Multiple myeloma (MM) constitutes approximately 1-2% of all cancers and about 17% of hematological malignancies, making it the second most common hematological malignancy. The neutrophil-to-lymphocyte ratio (NLR) is an inflammatory marker that has been shown to be associated with prognosis in solid tumors and lymphomas. In this study, we aimed to investigate the relationship between NLR values at diagnosis and survival, as well as other prognostic factors in patients with MM. Materials and Methods: This study included 196 patients diagnosed with MM at the Department of Hematology, Pamukkale University Faculty of Medicine Hospital, between January 2011 and December 2023. Clinical and laboratory data of the patients were retrospectively recorded from patient files and the hospital information system. The relationship among patients' demographic characteristics, laboratory parameters, clinical status, and the presence of renal dysfunction with survival and NLR was analyzed. Results: In our study, the cut-off value for NLR was determined as 1.8. There was a statistically significant relationship between OS and stage-3 disease, the presence of renal dysfunction, and age over 65. (p=0.001, p=0.001, p0.001) Similarly, a statistically significant association was found between NLR and the presence of renal dysfunction and age >65 years (p=0.012, p=0.035). Although survival decreased with increasing disease stage, no statistically significant relationship was found between OS and NLR values (p=0.064). Conclusion: The absence of a significant association between OS and NLR in our study may be related to factors such as oxidative stress, infection, and inflammation. However, the presence of common parameters affecting both NLR and OS, such as age, disease stage, and renal dysfunction, suggests that NLR may serve as a useful marker in assessing survival and prognosis.Amaç: Multipl myelom (MM), tüm kanserlerin yaklaşık %1 ila %2'sini, hematolojik malignitelerin ise yaklaşık olarak %17'sini oluşturan en sık 2. hematolojik malignitedir. Nötrofil-lenfosit oranı (NLR), solid kanserler ve lenfomalarda prognozla ilişkisi gösterilmiş bir inflamasyon belirtecidir. Bu çalışmada hastaların tanı anında NLR değerleri ile sağkalım ve diğer prognostik faktörler arasındaki ilişkiyi incelemeyi amaçladık. Gereç ve Yöntem: Bu çalışmaya Denizli Pamukkale Üniversitesi Tıp Fakültesi Hastanesi Hematoloji Bilim Dalı'nda Ocak 2011-Aralık 2023 arasında MM tanısı konulan 196 hasta dahil edildi. Hastalar ile ilgili klinik ve laboratuvar veriler hasta dosyalarından ve hastane bilgi sisteminden geriye dönük olarak kaydedildi. Hastaların demografik özellikleri, laboratuvar parametreleri, klinik durumları ve OKİT varlığı ile sağkalım ve NLR arasındaki ilişki analiz edildi. Bulgular: Çalışmamızda NLR için cut-off değer:1.8 olarak belirlendi. Ortalama sağkalım (OS) ve Evre III hastalık, renal disfonksiyon varlığı, >65 yaş arasında anlamlı istatistiksel açıdan anlamlı bir ilişki vardı. (p=0.001, p=0.001, p0.001) Yine benzer şekilde NLR ve renal disfonksiyon varlığı, >65 yaş arasında anlamlı istatistiksel açıdan anlamlı bir ilişki vardı.(p=0.012, p=0.035) Evre arttıkça sağkalım azalmasına rağmen OS ile NLR değerleri ile istatiksel olarak anlamlı bir ilişki saptanamadı. (p=0.064) Sonuç: Çalışmamızda OS ve NLR arasında ilişki saptanmaması oksidatif stres, enfeksiyon, inflamasyon vb gibi durumlara bağlı olabilir. Ancak NLR ve OS'yi etkileyen yaş, evre, renal disfonksiyon gibi ortak parametrelerin olması NLR değerinin sağkalım ve prognozu değerlendirmede yardımcı bir belirteç olduğunu göstermektedir
Examining the Role of Type D Personality Traits in Predicting Depression and Anxiety Symptoms in Women in the Postpartum Period
Objective: This study aimed to examine the role of type D personality traits in predicting depression and anxiety symptoms in women in the postpartum period. Method: The study is correlational and case-controlled. The sample consisted of 319 women in the postpartum period living in a province in western Türkiye. Type D Personality Scale (DS14), Edinburgh Postpartum Depression Scale (EPDS), and State-Trait Anxiety Inventory (STAI) were administered. Data were collected via Google Forms between January and February 2022. Results: 62.4% of women in the postpartum period had type D personality characteristics. Postpartum depression and state-trait anxiety levels of women with type D personality were significantly higher (p0.05). Additionally, the negative affect subscale of the Type D Personality Scale was the most significantly associated variable with postpartum depression (β=0.548, p0.05) and state-trait anxiety (β=0.709, p05). Conclusion: Personality traits can play an important role in the emergence of depression, anxiety and stress. Improving the coping and interpersonal skills of women with type D personality traits can help them to manage pregnancy, birth and motherhood related mental problems. © 2025 Turkish Journal of Psychiatry
Evaluation of social media privacy, internet addiction in adolescents who are victims of sexual abuse and digital awareness in their parents
Background: Childhood sexual abuse is the exploitation of a child by an adult for sexual purposes. Many cases go undetected and can occur across all socioeconomic levels, ages, genders, and regions. With the rise of internet use, abuse is increasingly occurring online, with some online relationships escalating to in-person sexual contact between the victim and offender. Objective: Our study hypothesizes that adolescents with high internet addiction and difficulty protecting their privacy online may be at greater risk for abuse, and that their parents may have low digital awareness. Methods: Adolescents completed the Sociodemographic Data Form, Social Media Privacy Protection Scale, and Young Internet Addiction Scale (short form), while parents completed the Digital Parent Awareness Scale. Statistical analyses were conducted using SPSS version 26. esults: The case group showed higher internet addiction and social media use, while the control group had better social media privacy protection skills. Although not statistically significant, parents in the case group had lower digital awareness. A negative relationship was observed between internet addiction and parental awareness. Discussion: Parental mediation of young people's social media use significantly impacts their privacy management.To prevent abuse, parents must understand the risks of the digital environment and the necessary precautions. Limitation: The primary limitation of this study is the limited sample size, which may restrict the generalizability of the findings
Impact of oral iron therapy on oxidative stress and dna damage in women of reproductive age
Objective: Iron deficiency anemia (IDA) is a condition that increases morbidity and mortality. This study investigated changes in oxidative stress, DNA damage, and hepcidin levels following therapy in individuals with IDA. Materials and Methods: The patient group consisted of 39 females diagnosed with IDA, and 36 age- and sex-matched controls were incorporated into our study (18-49 years). The patient group was treated with daily oral ferrous fumarate (304.2 mg, approximately 100 mg elemental iron) for one month. Measurements of total oxidant status (TOS), total antioxidant status (TAS), oxidative stress index (OSI), DNA damage (using the Comet assay), and hepcidin levels were conducted before and during therapy and compared between the patient and control groups. Results: Oxidative stress indicators and DNA damage assessed with the Comet assay were elevated in individuals with IDA (p=0.018) and decreased following treatment (p=0.002). TAS was reduced in individuals with IDA (p=0.02) but increased after treatment (p0.001). Although TOS levels were elevated in individuals with IDA, the difference was not statistically significant (p=0.10); however, TOS levels decreased after treatment (p=0.02). Hepcidin levels were significantly lower in individuals with IDA (p0.001) but increased during therapy (p0.001). Conclusion: This study demonstrates that just one month of oral iron therapy can reversibly improve oxidative stress and DNA damage. Hepcidin plays a critical role in maintaining iron homeostasis.Pamukkale University [2020TIPF028]Financial Disclosure: This study was supported by the Pamukkale University (Project Number: 2020TIPF028)
Automated Age Estimation From Opg Images and Patient Records Using Deep Feature Extraction and Modified Genetic-Random Forest
Background/Objectives: Dental age estimation is a vital component of forensic science, helping to determine the identity and actual age of an individual. However, its effectiveness is challenged by methodological variability and biological differences between individuals. Therefore, to overcome the drawbacks such as the dependence on manual measurements, requiring a lot of time and effort, and the difficulty of routine clinical application due to large sample sizes, we aimed to automatically estimate tooth age from panoramic radiographs (OPGs) using artificial intelligence (AI) algorithms. Methods: Two-Dimensional Deep Convolutional Neural Network (2D-DCNN) and One-Dimensional Deep Convolutional Neural Network (1D-DCNN) techniques were used to extract features from panoramic radiographs and patient records. To perform age estimation using feature information, Genetic algorithm (GA) and Random Forest algorithm (RF) were modified, combined, and defined as Modified Genetic-Random Forest Algorithm (MG-RF). The performance of the system used in our study was analyzed based on the MSE, MAE, RMSE, and R2 values calculated during the implementation of the code. Results: As a result of the applied algorithms, the MSE value was 0.00027, MAE value was 0.0079, RMSE was 0.0888, and R2 score was 0.999. Conclusions: The findings of our study indicate that the AI-based system employed herein is an effective tool for age detection. Consequently, we propose that this technology could be utilized in forensic sciences in the future
A comparison between parents with different attitudes towards topical fluoride application for their children: a cross-sectional study
Purpose: Although fluoride is known to be effective and safe, an increasing number of parents refuse to allow fluoride applications for their children. This study aimed to compare the parents who accepted and rejected fluoride application for their children in terms of their attitudes toward fluoride and vaccinations, sociodemographic characteristics, and source of knowledge. Materials and Methods: In this cross-sectional study, a previously validated questionnaire was administered to 85 parents who did not consent to have topical fluoride applied to their children's teeth (AF group) and the 143 parents who consented to have it applied (F group) in a pediatric dentistry clinic. Data were analysed using the independent t-test and chi-squared test. Results: In the F group, the number of those who disagreed with the statement that fluoride causes intellectual disability, autism, and damages the pineal gland was statistically significantly higher than in the AF group (p 0.05). The most common source of information for the AF group was the internet/social media (67.06%), while for the F group, it was dentists/ medical doctors (62.24%). More parents in the F group stated that childhood and Covid-19 vaccinations must be performed; this was a statistically significant difference (p 0.05). Conclusion: No relationship was found between fluoride hesitancy and the educational level of the parents. Most parents in the AF group have doubts and concerns about fluoride rather than being strongly opposed to it. Therefore, educational programs given to parents are likely to have a positive effect on their acquisition of correct information

people and present applicable strategies to help today's youth cope with issues such
as faith crises, religious doubts, and moral challenges. Firstly, the concepts of
spiritual support and counseling, the methods used to strengthen individuals'
relationships with spiritual values, and their effects on young people were discussed.
The need for spiritual guidance among youth in the rapidly changing dynamics of
the modern world was emphasized.
The project analyzes the methods Prophet Muhammad used in his relationships with
young people, focusing on exemplary leadership, empathy, and patience. The
Prophet’s delegation of responsibilities to youth boosted their individual and social
confidence, while his empathetic and patient approach resonated with their
emotional needs. These methods can provide effective solutions to the spiritual
emptiness and identity issues faced by modern youth.
Finally, practical recommendations for today’s youth were developed. Strategies
such as spiritual education within families, counseling programs in youth centers,
and the enhancement of spiritual content on digital platforms can strengthen the
moral and spiritual values of young people. The universal approach of Prophet
Muhammad towards youth serves as a robust guide for supporting their religious
and social development in the modern era
The effect of myofascial release applied to thoracolumbar fascia on flexibility, muscular endurance, and balance in healthy young adults: a single-blind randomized controlled trial
Context: Although cranial distant effects occur in self-myofascial release interventions for lower-extremity muscles and fascia, the results of caudal distant effects are still unclear. The aim of this study was to examine the distant effects of myofascial release applied to the thoracolumbar fascia together with exercise training on balance, lower-extremity flexibility, and muscular endurance in healthy young adults. Design: Single-blinded randomized control trial design. Methods: Thirty-six healthy participants aged 18-35 years were randomly divided into 3 groups: myofascial release and exercise group (group 1, n = 12), exercise group (group 2, n = 12), and control group (group 3, n = 12). Three days a week for 4 weeks, group 1 applied the thoracolumbar fascia foam roller massage together with the warm-up, muscular endurance, balance, and stretching exercise program, and group 2 applied the same exercise program except for the foam roller massage. No intervention was made in group 3. Flexibility was assessed with sit and reach test, muscular endurance with the 1-minute sit to stand test, and balance with star excursion balance test before the intervention and at the end of the fourth week. Results: Flexibility, muscular endurance, and dynamic balance values increased significantly in groups 1 and 2 after the intervention (P .05). When the difference values (Delta) of groups 1 and 2 were compared, there was a difference in favor of group 1 for flexibility, muscular endurance, and dynamic balance (P .05). Conclusions: The results of the study showed that the effect of the distant myofascial release technique added to the exercise training on flexibility, muscular endurance, and dynamic balance was greater than the exercise training alone
Sanat eğitimi bölümü öğrenci ve akademisyenlerinin uluslararası izmir duvar resimleri çalıştayı örneklerine ilişkin görüşleri
Bu araştırmada 2018 ve 2019 yıllarında gerçekleştirilen Uluslararası İzmir Duvar Resimleri Çalıştayı’ndan seçilmiş uygulama örneklerine ilişkin kentte ikamet eden sanat eğitimi bölümü öğrencileri ve akademisyenlerinin görüşleri alınmıştır. Görüşler problem durumuna bağlı olarak, duvar resimlerinin insan ve toplum üzerindeki etkileri, kent estetiğine etkisi, sanatsal değeri ve sanat eğitimine etkisi olmak üzere 4 alt boyutta çözümlenmiştir. Araştırmada nitel araştırma yöntemi kullanılmıştır ve durum çalışması desenlidir. Resimleri tanıyan, sanat eğitimci uzmanlardan ve sanat eğitimi almakta olan öğrencilerden oluşan amaçlı kişi örneklemesi yapılmıştır. Buna göre 6 akademisyen ve 61 öğrenci görüşme sorularını yanıtlamışlardır. Veriler yüz yüze görüşme ve uzaktan yazılı görüş alma tekniğiyle toplanmıştır.
Araştırma bulgularına bakıldığında, duvar resimlerinin insan ve toplum üzerindeki etkileri konusunu uzmanlar estetik farkındalık oluşturabileceği şeklinde yorumlarken, öğrenciler kültürel uyumsuzluğa dikkat çekmişlerdir. Her iki grup da kamusal alandaki resimlerin turizm potansiyeline vurgu yapmıştır. Kent estetiği kriterine göre duvar resimlerinin gri beton duvarları canlandırarak şehre dinamik bir etki kattığı ve bakış açısına göre kör duvarlardaki sürpriz etkisiyle izleyenleri heyecanlandırdığı görüşü hakimdir ancak resimlerin kendi içinde birbiriyle uyumlu olmadığı vurgulanmıştır. Duvar resimlerinin sokak sanatına özgü bir dil kullanarak yapıldığı görüşü vurgulanırken, illüstratif ve süslemeci unsurların sanatsal değerli zayıflattığı belirtilmiştir. Renk seçimi ve dokusu bakımından sanatsal değerinin olduğu yönünde yorumlar öğrenciler tarafından yapılmıştır. Duvar resimlerinin sanat eğitimi açısında estetik farkındalık yaratma ve kültürel bilinci artırma potansiyeline sahip olduğu uzman ve öğrenciler tarafında belirtilmiştir. Öğrencilerin beğenilerini, huzur bulma, umut olma, iyi gelme gibi duygusal ifadelerle anlatmaları dikkat çekicidir. Duvar resimlerinin örgün ve yaygın eğitime hizmet etmesi için çeşitli etkinliklerle desteklenmesi öneriler arasında yer almıştır.Sonuç olarak, mevcut duvar resimleri genel olarak olumlu değerlendirilirken, henüz tamamlanmamış bir projenin parçaları olarak görülmüştür. Bu bağlamda, yerel yönetimlere, eğitim kurumlarına, sanatçılara, kentte yaşayan vatandaşlara, ilgili bakanlıklara yönelik olarak yapıcı ve tamamlayıcı önerilerde bulunulmuştur.In this research, the opinions of art education department students and academicians residing in the city were taken regarding the selected application examples from the International İzmir Mural Paintings Workshop held in 2018 and 2019. Depending on the problem situation, the opinions were analyzed in 4 sub-dimensions: the effects of murals on human and society, the effect on urban aesthetics, artistic value and the effect on art education. Qualitative research method was used in the study and it is a case study design. Purposeful person sampling was made consisting of art educator experts who recognize the paintings and students who are receiving art education. Accordingly, 6 academicians and 61 students answered the interview questions. Data were collected through face-to-face interviews and remote written interviews.
In the light of the research findings, the experts interpreted the impact of murals on people and society as creating aesthetic awareness, while the students pointed to cultural incompatibility. Both groups emphasised the tourism potential of public murals. According to the criterion of urban aesthetics, the dominant opinion is that murals add dynamism to the city by enlivening grey concrete walls and excite viewers with the surprise effect on blind walls, but it is emphasised that the paintings are not compatible with each other. While it was emphasised that the murals were created using a language specific to street art, it was stated that the illustrative and ornamental elements weakened the artistic value. Students commented that the murals have artistic value in terms of colour choice and texture. It was noted by experts and students that murals have the potential to create aesthetic awareness and increase cultural awareness in terms of art education. It is noteworthy that students expressed their appreciation with emotional expressions such as finding peace, hope and

well-being. Supporting the murals with various activities to serve formal and non-formal education was one of the suggestions.
As a result, while the existing murals were generally appreciated, they were seen as part of an unfinished project. Constructive and complementary suggestions were made to local authorities, educational institutions, artists, city residents and relevant ministries
