Article Erken Cumhuriyet Dönemi Koruma ve Eğitim Vizyonuna Dair Bir Belge: Antikiteler ve Tarihi Eserlerden Derslerde Nasıl İstifade Edileceği Hakkında Andıç(Hacettepe University, 2025) Önge, M.Public consciousness for the conservation of the cultural heritage had been one of the most significant problems of Turkey hitherto. The founders of the republic, the intellectuals and the statesmen, who knew that the ignorance is the major cause of this problem, proposed the use of the cultural heritage of all types in the history lessons as the course material. This practice took place in the curriculum of the schools for the first time in 1926. In order to define its method better, a guidebook with the title “The Memorandum on the Usage of Antiquities and Historical Artifacts in the Courses”, is published in 1935, addressing the teachers. This guidebook, which was strangely named as “memorandum”, focuses on the idea of creating heritage conservation awareness in the public by making school age teenagers understand and embrace their cultural heritage. In this context, being completely different from the present-day authoritarian attitudes, the memorandum should be accepted as a significant document, which define a conservation attitude socializing heritage conservation by public education. This document also contains the evidences, which are related to the changes in terminology for defining cultural heritage in Türkiye, with respect to the changing attitudes and ways of understanding. Although it is not known how it had emerged, it is very probable that the memorandum was a part of the series of developments relating cultural heritage conservation in Türkiye, during the 1930’s. The memorandum text was consisting of twenty-four articles. The teachers were being instructed on how they are going to use the cultural heritage of all kinds in the courses, how they are going to make the cultural heritage meaningful for the students and make them enjoy the cultural heritage. It is noteworthy that the text contains application proposals like homework on the cultural heritage examples and establishment of school museums. Although the memorandum is an outdated document, the topics in it have timeless special importance. Therefore, the memorandum can be accepted as the expression of a cultural heritage attitude beyond its age. In this study, it is aimed to carry out extensive research on the memorandum. The memorandum is analyzed with respect to the heritage conservation related developments of its period and its importance is discussed in terms of its relation to present day conservation attitudes. In addition to being valuable as a document describing the conservation approaches of the early Republican Period, it has been revealed that the memorandum is up-to-date in terms of its content and an expression of the willing approach to conservation of its period. This study is prepared by using written and live sources. © 2025, Hacettepe University.

In the design, firstly a LED array is determined and a proper driver circuit that can provide the required optical power is designed, and the working lamp developed is tested under various conditions. The luminous output values of the designed LED working lamp are compared with those of a commercial working lamp, which uses a halogen bulb. It is evaluated that in automotive applications lamps using LEDs could be successfully utilized depending on the optical efficacy of the LED used, the designs of the LED driver and the reflector.Article Statistical Models for Porous Asphalt Mixtures Containing Pulverized Surface Dressed Pavement Material/Low-density Polyethylene Waste(MIM RESEARCH GROUP, 2025) Oner, Julide; Almusawı, Alı; Abdulrahman, Hassan Shuaibu; Ahmed, Nasiru IbrahimPorous asphalt (PA) mixtures typically contain a high proportion of coarse aggregates with minimal fine aggregates, along with a binder that creates ample space for water drainage. Since road construction consumes large quantities of aggregates, recycling and reusing materials have become common practices. This study focuses on developing PA by partially replacing traditional aggregates with pulverized surface-dressed pavement material (PSM) and modifying bitumen with low-density polyethylene (LDPE). The mixtures were produced using 60/70 penetration grade bitumen modified with 2%, 4%, and 6% LDPE waste and 20%, 40%, 60%, and 80% PSM. Adding LDPE waste to the bitumen altered key properties, such as the softening point, penetration, flashpoint, and ductility, resulting in a stiffer binder. Replacing aggregates with PSM reduced both stability and flow, leading to a lower Marshall quotient. Flow values for all trial mixes did not meet AAPA (2004) standards, while stability values slightly decreased as LDPE content increased from 2% to 6%. Despite this, all samples met the AAPA (2004) stability standard. The sample containing 2% LDPE and no PSM exhibited the highest Marshall quotient. Linear regression models were developed from experimental data to highlight the relationships between the measured responses and the variables. These polynomial equations demonstrated a strong correlation, indicated by high coefficients of determination. The study introduces an innovative approach by incorporating PSM and LDPE, largely unexplored in PA production, especially in Nigeria. The major societal benefits include reducing environmental pollution through plastic waste reuse, conserving natural aggregates, and promoting cost-effective construction practices. By advancing the use of recycled materials, this research supports sustainable infrastructure development while maintaining compliance with industry standards. © 2025 MIM Research Group.

The main tool to introduce such operators is the corresponding Abel's equation. Solvability conditions for the Abel's equations are shared. Semigroup property for fractional integrals are introduced. Integration by parts rule is given. Moreover, mean value theorems and related results are shared. At the end of the paper, some directions for some fractional operators are given.Article Kronik Hastalıklarda Duygu Düzenleme: Kalp ve Damar Sistemi Hastalıkları, Kanser, Migren, Fibromiyalji ve Sedef Hastalığı Üzerine Bir Derleme(Association for Clinical Psychology Research, 2023) Tuna, E.Emotion regulation (ER) involves conscious and automatic regulation of the occurrence, type, intensity, timing, and expression of emotions. Previous studies indicate that ER not only affects individuals’ mental health outcomes, but also plays a critical role in physical health as well. Especially in chronic diseases, how emotions are regulated shapes many patient variables including self-care, treatment adherence, and stress management; affecting both physical and psychological well-being. Furthermore, there is evidence that ER plays a role in initiation and prognosis of some chronic diseases. The aim of this review article was to summarize evidence regarding the association between chronic diseases and ER, and describe limitations in the existing studies in order to guide future research. To reach this aim, after a brief discussion of the mechanisms between emotions and health, we discussed research findings on ER in cardiovascular disease (CVD), cancer, migraine, fibromyalgia, and psoriasis, respectively. Findings indicate that emotion and ER play a role in the etiology of CVD; yet there are mixed findings regarding their role in the etiology of cancer. Research on migraine, psoriasis and fibromyalgia are rather correlational. Findings generally suggest that individuals with a chronic disease report more problems in ER as compared to healthy individuals. Frequent use of less adaptive strategies among patients have been related to less favorable outcomes such as psychopathology symptoms, bodily symptoms, and lower quality of life. Understanding ER in chronic diseases could guide the development of prevention and intervention programs aimed at increasing patients’ quality of life. The article ends with an evaluation of the literature and suggestions for clinical practice. © 2023 Klinik Psikoloji Araştırmaları Derneği.

In particular, existence and uniqueness of solutions of the fourth order differential equations are proved, deficiency indices theory of the corresponding minimal symmetric operators are studied. These symmetric operators are considered as acting on the single and direct sum Hilbert spaces. The latter one consists of three Hilbert spaces such that a squarely integrable space and two spaces of complex numbers. Moreover all maximal self-adjoint, maximal dissipative and maximal accumulative extensions of the minimal symmetric operators including direct sum operators are given in the single and direct sum Hilbert spaces.Article Common fixed point theorems in cone Banach spaces(Hacettepe Univ, FAC Sci, 2011) Abdeljawad, Thabet; Karapınar, Erdal; Taş, Kenan; Tas, Aysegul; Kumar, AnilRecently, E. Karapınar (Fixed Point Theorems in Cone Banach Spaces, Fixed Point Theory Applications, Article ID 609281, 9 pages, 2009) presented some fixed point theorems for self-mappings satisfying certain contraction principles on a cone Banach space.

We also propose a new test statistic for testing linear contrasts. Monte Carlo simulation results show that the MML estimators have higher efficiencies than the traditional least squares (LS) estimators and the proposed test has much better power and robustness properties than the normal theory test.Article Citation - WoS: 7Citation - Scopus: 10Extending a Sentiment Lexicon With Synonym-Antonym Datasets: Swnettr Plus(Tubitak Scientific & Technological Research Council Turkey, 2019) Genc, Burkay; Sever, Hayri; Saglam, FatihIn our previous studies on developing a general-purpose Turkish sentiment lexicon, we constructed SWNetTR-PLUS, a sentiment lexicon of 37K words. In this paper, we show how to use Turkish synonym and antonym word pairs to extend SWNetTR-PLUS by almost 33% to obtain SWNetTR++, a Turkish sentiment lexicon of 49K words. The extension was done by transferring the problem into the graph domain, where nodes are words, and edges are synonym- antonym relations between words, and propagating the existing tone and polarity scores to the newly added words using an algorithm we have developed. We tested the existing and new lexicons using a manually labeled Turkish news media corpus of 500 news texts. The results show that our method yielded a significantly more accurate lexicon than SWNetTR-PLUS, resulting in an accuracy increase from 72.2% to 80.4%. At this level, we have now maximized the accuracy rates of translation-based sentiment analysis approaches, which first translate a Turkish text to English and then do the analysis using English sentiment lexicons.Article Constructivism, Identity, 'manufactured Citizens: Russia's Citizenship Policies in Abkhazia and South Ossetia(Uluslararasi Iliskiler Konseyi dernegi, 2019) Ekinci, F. DidemThis paper discusses through a Constructivist perspective that the aim of maintaining influence via great power identity in the Near Abroad which preserved its significance in the post-1991 Russian foreign policy under the statist/pragmatist and civilizationist schools' influence, is reinforced through citizenship policies due to established collective identities with certain actors. The fact that Russia's conferral of citizenship to certain peoples through old collective identities via long-time great power identity is not a newly invented and ephemeral policy but that its roots reflect influence-driven subjecthood/citizenship policies since the Tsarist times, strengthens the assumption that the Near Abroad is an irreplaceable region for Russia which may practice similar policies towards other actors in the Near Abroad in the future.
