Annelerin erken çocukluk dönemine ilişkin tutumları ile çocukların benlik algısı arasındaki ilişkinin incelenmesi
No full textBu araştırmada, annelerin erken çocukluk dönemine ilişkin tutumları ile çocuklarının benlik algısı arasındaki ilişki incelenmiştir. Araştırma, ilişki arayıcı ve tanımlayıcı olarak kesitsel tipte yürütülen bir çalışmadır. Araştırmanın örneklemini, 2024-2025 eğitim-öğretim yılında Kayseri ili Melikgazi ilçesinde Milli Eğitim Bakanlığı'na iki anaokula devam eden 3-6 yaş grubu çocukların (N=264) anneleri oluşturmaktadır. Katılımcı seçiminde gönüllülük esas alınmış ve dahil edilme kriterlerini karşılayan toplam 160 kişi araştırma kapsamına alınmıştır. Araştırmanın verileri "Tanıtıcı Bilgi Formu", "Aile Hayatı ve Çocuk Yetiştirme Tutum Ölçeği (PARI)", ve "36-72 Aylık Çocuklar İçin Demoulin Benlik Algısı Testi"ile toplanmıştır. Araştırmada kullanılan veriler, IBM SPSS Statistics 22.0 paket programı aracılığıyla analiz edilmiştir. Çalışmadan elde edilen bulgulara göre; Aşırı Koruyuculuk alt boyutu ortalamasının 39,94 ± 8,288, Demokratik Davranma ve Eşitlik Tanıma puan ortalamasının 26,53 ± 2,763, Ev Kadınlığını Reddetme alt boyutu puan ortalamasının 28,99 ± 7,141 olduğu bulunmuştur. Karı-Koca Geçimsizliği alt boyutunun ortalama 13,87 ± 4,039 ile düşük ortalamaya sahip olduğu ve Baskı ve Disiplin alt boyutu ortalamasının 36,57 ± 7,465 olarak orta düzeyde sergilendiği görülmüştür. Ayrıca, çocukların Öz-Yeterlik puan ortalamaları 33,31 ± 3,350, Öz-Saygı puan ortalamaları 40,09 ± 3,956 ve toplam puan ortalamaları 73,39± 6,605 olarak yüksek düzeyde bulunmuştur. Aile hayatı özelliklerinin çocukların benlik algısında istatistiksel olarak anlamlı bir ilişki bulunmamasıyla birlikte, özellikle geçimsizlik yaşayan ailelerde çocukların öz saygı düzeylerinin düştüğü belirlenmiştir. Çocuk benlik algısı üzerinde sadece bireysel ebveveyn tutumlarının değil, ailesel işlevlerin de etkili olduğu sonucuna varılmakla birlikte, konuya ilişkin daha geniş örneklemli ve uzun süreli deneysel çalışmalar yapılması önerilebilir.This study examined the relationship between mothers' attitudes toward early childhood and their children's self-perception. The study sample consisted of mothers of children aged 3-6 (N=264) attending two Ministry of National Education kindergartens in the Melikgazi district of Kayseri province during the 2024-2025 academic year. Participant selection was based on volunteering, and a total of 160 individuals who met the inclusion criteria were included in the study. Data were collected using the "Introductory Form," the "Attitudes to Family Life and Child-Raising Scale (PARI)," and the "Demoulin Self-Perception Test for Children Aged 36-72 Months." Data used in the study were analyzed using the IBM SPSS Statistics 22.0 package program. According to the findings obtained from the study, the mean score for the Overprotection sub-dimension was found to be 39.94 ± 8.288, the mean score for Democratic Behavior and Recognition of Equality was 26.53 ± 2.763, and the mean score for the Rejection of Housewifery sub-dimension was 28.99 ± 7.141. The mean score for the Spousal Disagreement sub-dimension was low at 13.87 ± 4.039, and the mean score for the Pressure and Discipline sub-dimension was moderate at 36.57 ± 7.465. Additionally, the children's mean Self-Efficacy score was 33.31 ± 3.350, their mean Self-Esteem score was 40.09 ± 3.956, and their total mean score was 73.39 ± 6.605, all of which were found to be high. While there was no statistically significant relationship between family life characteristics and children's self-perception, it was determined that children's self-esteem levels decreased, especially in families experiencing conflict. Although it is concluded that not only individual parental attitudes but also familial functions have an impact on children's self-perception, it is recommended that larger sample and longer-term experimental studies be conducted on the subject

Alternatif modeller ise bu değişkenlerin çevrim içi sosyal sermaye üzerindeki dolaylı etkilerini destekler nitelikte bulunmuştur. Genel olarak sonuçlar, çevrim içi sosyal sermaye ile topluluk hissi, algılanan sosyal destek ve psikolojik iyi oluş arasında güçlü pozitif ilişkiler olduğunu ve bireylerin dijital etkileşimlerinin sosyal bağlılıklarını artırarak psikolojik iyilik hallerini desteklediğini ortaya koymaktadır.This study examined the relationships between online social capital and sense of community, perceived social support, and psychological well-being in adults. A total of 304 adults aged 25 and over, who are active social media users, participated in the study. Data were collected using the Online Social Capital Scale, Sense of Community Scale, Multidimensional Perceived Social Support Scale, Psychological Well-Being Scale, and a Personal Information Form. The study was conducted within the framework of a structural equation model tested in two stages. In the first stage, the validity and reliability of the constructs were assessed by validating the measurement model (GFI = 0.93; CFI = 0.96; RMSEA = 0.076). In the second stage, the structural model was tested according to the proposed hypotheses, and the significance of indirect effects was evaluated using the bootstrap method. The results from the structural equation model indicated that sense of community, perceived social support, and psychological well-being significantly and effectively explained online social capital (GFI = 0.932; CFI = 0.964; RMSEA = 0.076). Alternative models also supported the indirect effects of these variables on online social capital. Overall, the findings suggest strong positive relationships between online social capital and sense of community, perceived social support, and psychological well-being, indicating that individuals' digital interactions enhance their psychological well-being by fostering social connectedness

Kolayda örnekleme yöntemiyle seçilen çalışma grubunu, yaşları 11-19 arasında değişen 722 ergen oluşturmaktadır (%66,1 kız, %33,9 erkek). Yaş ve gelişimsel farklılıklar gözetilerek katılımcılar ortaokul ve lise olmak üzere iki gruba ayrılmış; veriler hem çevrim içi hem yüz yüze toplanmıştır. Veriler, betimsel istatistikler, bağımsız örneklem t testi, tek yönlü ANOVA, korelasyon ve çoklu doğrusal regresyon analizleriyle değerlendirilmiştir. T testiyle kademe ve cinsiyete göre; ANOVA ile sınıf düzeyine göre karakter güçleri ve psikolojik sağlamlık düzeyleri incelenmiştir. Korelasyon analizi değişkenler arası ilişkileri, regresyon analizleri ise karakter güçlerinin psikolojik sağlamlığı yordama düzeyini belirlemiştir. Bulgulara göre, ortaokul öğrencileri lise öğrencilerine kıyasla daha yüksek düzeyde iyimserlik ve kararlılık sergilemiştir. Cinsiyete göre farklılıklar; ortaokulda cesaret, maneviyat, sakinlik ve psikolojik sağlamlıkta; lisede bilgelik, cesaret, dürüstlük, nezaket, sakinlik ve psikolojik sağlamlıkta gözlenmiş; çoğu fark erkek öğrenciler lehine olmuştur. Ortaokulda 7. sınıf öğrencileri alçakgönüllülükte, 6. sınıflar ise iyimserlik, kararlılık ve psikolojik sağlamlıkta öne çıkmıştır. Lisede 11. sınıf öğrencilerinin psikolojik sağlamlık düzeyi 9. sınıflardan yüksektir. Çoklu doğrusal regresyon analizine göre; ortaokul düzeyinde Kısa Psikolojik Sağlamlık Ölçeği modelinde affedicilik, alçakgönüllülük, iyimserlik, sakinlik ve yakınlık psikolojik sağlamlığın %31.5'ini; Connor-Davidson Ölçeği modelinde alçakgönüllülük, cesaret, iyimserlik ve kararlılık %39.9'unu açıklamaktadır. Lise düzeyinde ise sırasıyla %38.9 ve %52 oranında açıklayıcılık bulunmuştur. İlk modelde affedicilik, cesaret, iyimserlik, nezaket ve sakinlik; ikinci modelde bilgelik, cesaret, dürüstlük, iyimserlik, kararlılık ve sakinlik etkili olmuştur.The primary aim of this study is to examine the relationship between adolescents' character strengths and their levels of psychological resilience. In line with the post-positivist paradigm, this cross-sectional and correlational study was conducted using a quantitative approach. The data collection tools included the Personal Information Form, Character Growth Index, Brief Resilience Scale, and the Connor-Davidson Resilience Scale - Short Form. The study group, selected through a convenience sampling method, consisted of 722 adolescents aged between 11 and 19 (66.1% female, 33.9% male). Considering age and developmental differences, participants were divided into two groups: middle school and high school. Data were collected through both online and face-to-face methods. The data were analyzed using descriptive statistics, independent samples t-test, one-way ANOVA, correlation, and multiple linear regression analyses. The t-test was used to compare character strengths and resilience levels based on educational stage and gender, while ANOVA was employed to examine differences across grade levels. Correlation analysis assessed relationships between variables, and regression analyses determined the predictive power of character strengths on psychological resilience. According to the findings, middle school students exhibited higher levels of optimism and perseverance compared to high school students. Gender-based differences were found in courage, spirituality, composure, and resilience at the middle school level, and in wisdom, courage, honesty, kindness, composure, and resilience at the high school level, mostly in favor of male students. Among middle school students, seventh graders stood out in humility, while sixth graders displayed higher levels of optimism, perseverance, and resilience. In high school, eleventh graders had higher resilience scores than ninth graders. Multiple regression analyses revealed that, at the middle school level, forgiveness, humility, optimism, composure, and intimacy explained 31.5% of resilience (Brief Resilience Scale), while humility, courage, optimism, and perseverance explained 39.9% (Connor-Davidson Scale). At the high school level, the explanatory power of the models was 38.9% and 52%, respectively. In the first model, forgiveness, courage, optimism, kindness, and composure were significant predictors, whereas in the second model, wisdom, courage, honesty, optimism, perseverance, and composure were found to be influential
Dynamical analyses and dispersive soliton solutions to the nonlinear fractional model in stratified fluids
No full textThis study explores the bifurcation analysis, sensitivity analysis (SA), stability analysis, and exact solitonic wave profiles for the time-fractional Benjamin-Ono (BO) equation, which models internal waves in stratified fluids, especially where dispersive effects play a significant role. These solutions are crucial for understanding ocean engineering and mathematical physics phenomena. The BO equation simulates deep-water waves, making it essential for ocean engineering applications. We employ some diverse strategies such as the new extended direct algebraic method, generalized Arnous method, and ansatz method to extract novel dispersive wave solutions. These solutions exhibit diverse shapes, such as hyperbolic, singular periodic, exponential, rational function solutions and solitary waves including dark, singular, bright, combo, and complex solutions. Our main goal is to analyze the dynamic characteristics of the model by conducting bifurcation and SA and identify the corresponding Hamiltonian function. To ensure validity, we also conduct stability analysis using linear stability theory and outline constraint conditions. Furthermore, the bifurcation of phase portraits of ordinary differential equations corresponding to partial differential equations under investigation is also analyzed. We also demonstrate the fractional behavior of our results through visualizations (2D, 3D, contour, and density plots) by selecting suitable parametric values. Our reported results are verified using Mathematica to guarantee accuracy and validity. A detailed comparison with existing results highlights the novelty of our findings. This research contributes significantly to understand wave dynamics in nonlinear phenomena and the unique outcomes explored in this research will play a significant role in the forthcoming investigation of nonlinear problems. Moreover, the novelty of this study lies in the fact that the proposed model has not been previously explored using the aforementioned advanced methods and comprehensive dynamical analyses. This study pioneers the exploration of the fractional BO equation, yielding unique analytical results. Our techniques efficiently identify accurate solitary pulse solutions to nonlinear dynamical models with fractional parameters, making them highly successful in modeling deep-water internal waves. Our computational analytical tools are also straightforward, transparent, and reliable, reducing complexity while widening applicability. The acquired solutions are expected to have a profound impact on the study of wave propagation and related fields, offering new insights and perspectives that can inform future research and applications
Rh2MnGa full Heusler alloy: Unravelled physical properties and strain-induced magnetic moment using DFT
No full textAbstract
In this work, we will investigate structural, electronic, magnetic, and thermodynamic properties using density functional theory (DFT) and the quasi-harmonic Debye model. We consider ferromagnetic (FM) and non-magnetic (NM) states for L2(1) and Hg2CuTi-type crystal structures. The best stability is obtained for ferromagnetic Rh2MnGa in a Cu2MnAl structure with a lattice parameter of 6.07 & Aring; and a total magnetic moment of 4.11 mu B. The compressive strain range from -6% to +4% tensile strain maintains the ferromagnetic nature and enhances the magnetic moment up to 4.39 mu B. The formation energy confirms the inherent stability of Rh2MnGa. Other important thermodynamic parameters such as the expansion coefficient (alpha), heat capacity (CV), Debye temperature (theta D) and Gr & uuml;neisen constant (gamma) are also estimated in this work
The simpler modified fried frailty scale predicts 2-year mortality in older adults with heart failure: a pilot study
Full text linkAbstract
ObjectiveThe Simpler Modified Fried Frailty Scale (SMFFS) has recently been developed from the original Fried scale to ease its use in clinical practice, by transforming the items requiring measurements into the self-reported inquiries. Its predictive validity needs to be clarified, especially in populations with a high prevalence of frailty, such as patients with heart failure (HF). Primary aim of this study is to find out the prevalence of frailty in older patients with HF by using SMFFS and show its concordance with other frailty assessment tools. Secondary aim is to reveal whether SMFFS is useful to predict mortality in follow-up.MethodThis is a prospective, follow-up study including older adults (>= 65 years) with HF. SMFFS was used to assess frailty phenotype and presence of >= 3 items was accepted as frailty. FRAIL scale, the Study of Osteoporosis Fractures (SOF) index, and Edmonton Frailty Scale (EFS) were alternatively used to study the correlation of SMFFS with different scales. Cox-regression analysis was performed to identify whether SMFFS-defined frailty could predict mortality in follow-up, with adjusting for a list of clinical characteristics and geriatric syndromes.FindingsAmong 101 patients with HF, 44 (42.8%) were female. Mean age was 75.8 +/- 7.6 and frailty prevalence was 63.4% according to SMFFS. SMFFS showed a strong correlation with the other frailty scales. In a median follow-up of 759 days, cardiomegaly, increased pulmonary artery pressure (PAP) and frailty defined by SMFFS were the only predictors of mortality in older adults with HF after adjustments for age, falls in the previous year, undernutrition, probable sarcopenia, functional impairments, and quality of life [HR (95% CI) were 3.88 (1.05-14.3), 1.05 (1.01-1.09), and 10.96 (1.07-112.05) (p = 0.027); for older age, PAP, and frailty, respectively].ConclusionsAs a self-reported screening tool, SMFFS was independently associated with mortality in a median follow-up of two years. Frailty assessment recommended by the guidelines for risk stratification in patients with HF seems to be more effectively integrated into routine HF practice with the use of the easy and practical SMFFS. Further large scale studies are needed to support the predictive validity of SMFFS in older patients with HF
Optical properties of repaired additively manufactured resin composites and zirconia and subtractively manufactured ceramics: a comparative study of composite resins
Full text linkAbstract
Objective This study aims to examine color properties of repairs made with various composites on restorations produced through additive-manufactured resin composites (AM-RC) and zirconia (AM-Z) or subtractive manufacturing (SM) after coffee thermocycling (CTC). Materials and methods Disk-shaped specimens (& Oslash;10 x 2 mm; N = 120) were fabricated using six different material groups: additively manufactured resin composite (AM-RC) materials (Crowntec [C], NextDent [ND]), additively manufactured zirconia (AM-Z) materials (Lithoz [LI], INNI-Cera [IN]), and subtractively manufactured (SM) materials (CEREC Tessera [ALD], Vita Enamic [EN]). Subsequently, each group was further subdivided into two subgroups (n = 10) based on the type of repair using two different composites resins: Clearfil Majesty Posterior (CL) (n = 60) and Filtek Z350 (FZ) (n = 60). Specimens underwent thermal cycling (CTC), consisting of 10,000 cycles between 5 degrees C and 55 degrees C. Color measurements were performed both before and after thermal cycling for all materials. Color discrepancies (Delta E00) and relative translucency parameters (RTPs) were calculated. Statistical analyses were conducted at a significance level of alpha = 0.05. Results A one-way ANOVA of Delta E00 values between CL and FZ revealed a significant difference (P = 0.007), with FZ exhibiting higher Delta E00 values. Significant differences in Delta E00 values were also observed among IN, C, and ND after CTC (P < 0.05). ALD demonstrated the lowest amount color change (P < 0.05). LI and EN colors showed no significant difference (P = 0.75). Following CTC, C, ND, and IN colors matched CL. In contrast, ALD, EN, and L colors exhibited significant differences (P <= 0.050). FZ showed a poor color match with all AM and SM materials. Furthermore, significant differences in RTP values were identified for all specimens (P < 0.001), with LI having the highest RTP and IN the lowest (P < 0.001). Conclusion The optical properties of composite and ceramic materials, as well as their stability over time, are crucial for their durability. ALD demonstrated the most consistent color stability. While the CL repair composites experienced some color changes, these changes remained within acceptable limits. Additionally, the LI (AM-Z) material exhibited the highest level of translucency

Marjolin ulcer: a rare clinical entity that every health professional should be informed about: a narrative review
Full text linkAbstract
Marjolin ulcer is a term used to refer to malignant degeneration of aggressive nature
associated with chronic burn scars or chronic wounds most of the time. Marjolin
ulcers are more common in men and are usually diagnosed in the 5th decade
of life. It usually has a relatively poor prognosis because it is diagnosed late, and
the mortality rate is around 20% on the average. It is important for all healthcare
professionals who provide wound care to be knowledgeable about this issue. The
patients with chronic wounds and long standing scars should be followed-up
closely in this regard. Early and effective treatment of burns and chronic wounds is
mandatory to prevent this condition. Appropriate follow-up and early biopsy at the
time of detection of any suspicious change improve the prognosis and survival of
patients as this approach will provide early diagnosis of Marjolin ulcers.

Bioactive potential of Origanum heracleoticum L. essential oil: Chemical composition and its antimicrobial and anticancer properties
Full text linkAbstract
Oregano (Origanum heracleoticum L.) is a widely consumed aromatic spice,
recognized as a medicinal plant due to its diverse biological and pharmaceutical
properties. Essential oils (EOs) exhibit remarkable biological activities,
primarily attributed to their high concentrations of volatile aromatic compounds.
This study aimed to determine the chemical composition of Bulgarian oregano
essential oil (OEO) and evaluate its biological activities, including anticancer,
antimicrobial, anti-biofilm, and anti-quorum sensing properties. Chemical
analysis revealed that carvacrol (76.90%) and p-cymene (12.84%) were the
predominant components of OEO. The MTT assay demonstrated that OEO
significantly reduced the viability of human lung adenocarcinoma epithelial
cells (A549), human hepatocellular carcinoma cells (HepG2), and human breast
adenocarcinoma cells (MDA-MB-231) at all tested concentrations (3.9-1000
µg/mL), while exhibiting considerably lower toxicity towards healthy mouse
fibroblast cells (L929). Among the tested cancer cell lines, A549 cells were the
most sensitive to OEO, with IC50 values indicating greater cytotoxicity towards
A549 and MDA-MB-231 cells at lower concentrations. The antimicrobial,
anti-biofilm, and anti-quorum sensing (anti-violacein) activities of OEO
were assessed against Staphylococcus aureus ATCC 25923, Pseudomonas
aeruginosa PA01, P. aeruginosa ATCC 27853, Candida albicans ATCC 10231,
and Chromobacterium violaceum ATCC 12472. The results revealed that OEO
exhibits potent antimicrobial and anti-biofilm activities against a range of
microorganisms
