Servet-i Fünûn Edebiyatında Yeni İfade veya Kusursuz Dil Arayışları
Authors: GÜZEL Ekrem
Published: December 2024

Servet-i Fünûn nesli edipleri, değişen ve dönüşen insanın düşünce ve duygularını yansıtmak için yeni bir ifade ve dile ihtiyaç olduğunu düşünmüşlerdir. Bu düşünce doğrultusunda, özellikle de şiirde kullandıkları ifadeler ve dil tercihleri, onları Türk edebiyatı tarihinde kritik bir noktaya taşımıştır. Birçok yenilik getirmekle birlikte, tartışmalara da sebep olmuşlardır. Bu anlamda Servet-i Fünûncular, başta Ahmet Midhat olmak üzere, dekadans olmakla, dilde yozlaşma yaratmakla suçlanırlar. Bu tarz ithamlara, cevap vermek ve yarattıkları yeni edebiyat dilinin mahiyetini açıklamak için teorik yazılar kaleme alırlar. Tartışmalar etrafında oluşan yazılardan başka onların edebî metinlerinde de bu yeni dili, ifadeyi açıklama niyeti taşıdıkları görülür. Bu niyetin zamanla tartışmaların dışına taşarak hem teorik yazılarda hem de edebî metinlerde görülen bir söylem biçimine dönüştüğü söylenebilir. Cenab Şahabeddin “Yeni Elfâz”, “Yeni Ta’birât” ve “Esâlib-i Ezmine” başlıklı teorik yazılarında dilde ne yaptıklarını anlatmakla kalmaz, onu aynı zamanda estetik bir endişe olarak şiirlerinde işler. Tevfik Fikret’in edebiyat yazılarında ve şiirlerinde de gördüğümüz bu durum; yine Halit Ziya’nın Mai ve Siyah romanında, Ahmet Cemil üzerinden kurmaca düzlemine taşınır. Böylece edebi eserlerde işlenen bir konu ve söylem hâline gelir.

Bu anlamda, Servet-i Fünûncular ürettikleri yeni ifade söylemini dil-insan, dil-düşünce arasındaki ilişkiden hareket ederek izah etme yoluna giderler. Günlük/standart dilin canlı, değişen ve dönüşen bir doğaya sahip olan insanı yansıtmada yetersiz kaldığını ve bu yüzden insanın varoluşunu tam olarak verebilecek yerli yerinde bir ifade arayışı içerisinde olduklarını açıklamaya çalışırlar. Dilin varlığı açığa çıkarıcı yönü üzerinde dururlar. Bu çerçevede bu makalenin amacı, Servet-i Fünûn nesli yazar, şair ve eleştirmenlerin yeni ifadeye ve dile (elfaz) dair izahatlarının zamanla bir söylem hâlini almasını ve bunun onların edebî metinlerinde estetik bir endişe olarak ortaya çıkmasını ele almaktır. Bu nesil ediplerinin teorik yazıları, eleştirileri ve tartışmalarında savundukları, yaratmak istedikleri “yeni ifade” tarzını ve kusursuz dil arayışlarını nasıl açıkladıklarına dikkat çekmek ve bunun ardında yatan niyete ve felsefeye ışık tutmaktır. Bu anlamda Cenab Şahabeddin, Tevfik Fikret, Halid Ziya, Hüseyin Cahit gibi topluluğun önde gelen simalarının yeni ifadeyi, yerli yerinde ve kusursuz bir ifade arayışının nasıl tezahür ettiğini onların bazı teorik yazıları, roman ve şiirleri üzerinden göstermeye çalışmaktır. Böylece konuyu edebiyatın özerkliği, dilin imkânları ve sınırları, düşünce ve duyguların ne kadar aktarılabilir olduğu dolayımında ele almaktır.

Authors: Mohammed Anees
Published: December 2024

In this research, the radioactivity of a group of soft drinks available in the markets of Thi-Qar Governorate (southern Iraq) was measured. Seven samples were selected, the most available and consumed by people. The idea of ​​the research is to use a gamma spectrometer NaI (Tl) system to study the presence of radioactivity in these seven samples packaged in glass bottles and their counterparts packaged in metal cans for comparison. The results show that the specific activity values for the bottle samples ranged between 15.787 - 20.160 Bq.kg-1 for K-40, while ranging between (0.112 - 1.194) Bq.kg-1 for U-238. As for the third nuclide Th-232, its values were 0.098 - 0.200 Bq.kg-1. On the other hand, the symmetric radioactivity for the can samples was recorded between 17.888 - 20.885 Bq.kg-1, 0.185 - 1.406 Bq.kg-1, and 0.218 - 0.272 Bq.kg-1 for the corresponding three radioactive nuclides K-40, U-238, and Th-232, respectively. The results of the hazard factors show that the maximum value​​ studied was for (Sprite) sample, while the minimum value was for (Seven Up), each for bottle samples. Concerning to the can samples, the maximum value ​​of these hazard factors studied was for the Fanta sample, while the minimum value was for (Dew). Furthermore, all these values of the hazard factors studied were higher for the can samples than for the symmetric bottles, but with a very small increase. All the radioactive factors studied in them were lower than the global
EDUCATION EXPENDITURES, SCHOOL ENROLLMENT - ATTAINMENT IMPACT ON ECONOMIC DEVELOPMENT: THE WESTERN BALKAN COUNTRIES
Authors: KAMBERAJ Altina , KAMBERAJ Naim
Published: December 2024

This paper comprehensively examines the intricate relationship between education expenditures, school enrollment rates, and educational attainment levels on the economic development of Western Balkan countries from 2010 to 2022. By employing a  quantitative methodology that encompasses Ordinary Least Squares (OLS), Fixed Effects (FE), Random Effects (RE), and the Hausman and Taylor instrumental variable approach, the study aims to uncover the dynamics that influence economic growth in this region. The findings indicate that general government education expenditures do not statistically affect GDP per capita, suggesting that merely increasing funding for education may not directly translate into economic benefits.
In contrast, the analysis highlights a concerning trend where high unemployment rates among individuals holding advanced degrees, such as PhDs and master's degrees, negatively impact GDP per capita. This underscores the importance of aligning educational outcomes with labor market needs. Additionally, the study reveals a positive correlation between per capita GDP and both school enrollment figures and overall academic achievement within the region. These insights contribute to a deeper understanding of the complex interplay between education and economic development, emphasizing the need for targeted policies that enhance educational quality and relevance to foster sustainable economic growth in the Western Balkans.

Authors: Restrepo Marin Luisa Maria , Abreu Plata Eneyda , Serra David Jonathan , Arboleda Lopera Adolfo Emilio , Camargo Castro Diego Alejandro
Published: December 2024

El ciclo hidrosocial refiere al vínculo histórico, geográfico y antropológico que las poblaciones han ido desarrollando con los procesos del agua, en el territorio enunciado por Colombia anfibia: un país de humedales (2015) (Jaramillo Villa et al., 2016). En este contexto, encontramos un vacío dada la falta de estudios enfocados en el análisis de los procesos de adaptación antrópica a las cuencas hídricas de la ciudad de Medellín, específicamente en la quebrada de La Honda, ubicada en el barrio homónimo de la comuna 3 Manrique (Medellín). El presente trabajo, en armonía con el Plan de Acción Climática de Medellín, tiene como objetivo investigar el ciclo hidrosocial del barrio y de la quebrada de La Honda, mediante una sinergia investigativa entre la Universidad Santo Tomás (seccionales de Medellín y de Bucaramanga), el Instituto de Derechos Humanos, Reconciliación y Paz (USTAMED) y la comunidad local. Durante la investigación se implementó la metodología participativa ‘Acciones transformadoras La Honda’, estructurada en tres momentos principales denominados: ‘Construyendo lazos’; ‘Cocreación’; y ‘Taller de creación’. Esta permitió instaurar lazos entre la sociedad civil y la comunidad académica en temas fundamentales como: desarrollo ambiental sostenible, derechos humanos, construcción de política pública y escenarios de paz. La conclusión principal se centra en unas premisas de diseño arquitectónico como ‘soluciones basadas en la naturaleza’, elaboradas conjuntamente entre la población del barrio, los estudiantes y los docentes investigadores, con el propósito de llegar a futuro a una obra construida vinculando entidades público-privadas.

Authors: Lim Li Rang , Lee Yaeji , Park Chanhyuk , Kim Hyung Mi
Published: December 2024

Objective: This study aimed to examine the relationship between adherence to the Mediterranean diet (MD) and sleep quality in a Korean population. Methods: We analyzed data from 7,861 participants aged 40–69 years in the Korean Genome and Epidemiology Study cohort. MD adherence was measured using the Korean version of the Mediterranean Diet Adherence Screener, and sleep duration and poor sleep quality indicators were evaluated. Dietary intake was assessed using a 103-item food frequency questionnaire. After propensity score matching, the analysis included 1,485 men and 2,676 women. Sex-stratified logistic regression models were conducted, adjusting for age, education, body mass index, physical activity, smoking, alcohol consumption, energy intake, household income, employment status, marital status, residential area, and chronic diseases. Results: No significant association was observed between MD adherence and poor sleep quality in men. In women, higher adherence to the MD was associated with lower odds of reporting multiple poor sleep quality indicators, with an odds ratio (OR) of 0.82 (95% confidence interval [CI]: 0.69–0.97, p=0.024) for 2–3 indicators and 0.83 (95% CI: 0.72–0.97, p=0.018) for ≥4 indicators. Additionally, higher adherence was significantly associated with reduced odds of not feeling rested in the morning (OR: 0.80, 95% CI: 0.66–0.97, p=0.024), suggesting a sex-specific effect of the MD on sleep quality. Conclusion: MD adherence did not affect sleep quality in men but was associated with better sleep quality in women, particularly by reducing morning fatigue. Therefore, promoting MD may be critical in improving sleep and reducing health risks in women.

Published: December 2024

File carving is a method for recovering files using software such as Foremost and Autopsy. The recovery is conducted for deleted files or formatted devices. Popularity Solid State Drive (SSD) has outperformed Hard Disk Drive (HDD) because SSD is faster, more efficient, and shock resistant. However, recovering SSD devices have a lower probability success rate than HDD because the security system often hampers files recovered on SSD. Based on previous research, the success rate of Security Digital High Capacity (SDHC) only achieved 50% more than SSD, whereas SSD can only return 85.7% of its success. Forensics Digital is a part of Forensics Knowledge for deliver valid digital evidence for law investigation. This research aims to increase the success rate of recovery files using two different software: Foremost and Autopsy. The research uses a 512GB Eaget brand SSD with a New Technology File System (NTFS). The file carving is also conducted using the Association of Chief Police Officers (ACPO) method. APCO has several stages: Planning, Capture, Analysis, and Presentation. The experiment results show that Autopsy software with deep recover mode returned 81 out of 88 files (92%), whereas Foremost software run on Debian to make sure no virus on device that could damage computer especially windows system. First attempt recovery can only return 46 out of 88 files (52%). The findings show that the Autopsy software has a higher successful return rate and can be used for evidence in law enforcement and digital forensics investigations.

La vil·la romana del Collet està situada al litoral de l’extrem nord‑est de la península Ibèrica. Les seves primeres fases de la vil·la, des de finals del segle II aC fins els anys 60‑70 dC, estan molt vinculades a l’explotació vitivinícola. En aquells darrers anys va ser objecte d’una intensa reforma que es va perllongar fins al seu abandonament en el segle V. Tot i que des d’inicis del segle IV, el sector de la vil·la més pròxim al mar devia estar abandonat. En aquest article s’estudien les 27 monedes localitzades fins l’actualitat en aquesta vil·la amb l’objectiu de complementar la identificació de les seves fases.

To study the functioning of constructed discrete-continuous stochastic Markov models of the surveying-geodetic network with full and current recovery. To perform a numerical calculation of reliability, safety and efficiency indicators: readiness ratio, limit probability states, mean time to failure, mean time between failures.

Methodology. A model of SGN functioning is built in the form of a graph of states and transitions with current and full recovery. Based on the model in the Mathcad software, the availability factor, mean time to failure, mean time between failures are calculated. The following graphs are built: readiness functions, probabilities of operation until the first failure, and frequency of getting into an emergency situation.

Findings. Constructed discrete-continuous stochastic Markov reliability models of the boundary probability states, mean time between failures, mean time to the first failure have been analyzed. The probability of fault-free operation is presented graphically in the form of a transition graph, which describes the logic of the operation of the SGN. Based on the graph of states and transitions (graphical model) according to the Kolmogorov-Chapman algorithm, an analytical model of the reliability behavior of the surveying-geodetic network was built. A system of linear Kolmogorov-Chapman differential equations was compiled and solved. The distribution of probabilities of being in each state of the surveying-geodetic network has been obtained.

Originality. For the first time in surveying practice, a reasonable choice of a discrete-continuous stochastic model of the functioning of a surveying-geodetic network based on the application of the state space method has been made. This model most fully describes the process of functioning (behavior) of the dynamic system. Dependencies between reliability indicators and safety indicators are established. It is recommended to use a model with ongoing network recovery, which allows you to maintain a given level of reliability through timely maintenance (recovery).

Practical value. The most expedient time for restoration of geodetic points with certain failure intensity parameters has been determined. It has been done in order to maintain the SGN in an operational state with a given level of reliability. Current network recovery makes it possible to maintain reliability at the desired level. In the case of complete restoration of the SGN, the readiness factor will be lower, but such a system will be significantly cheaper.

Purpose. The research is aimed at determining the qualitative and quantitative characteristics of complex limestone processing from the Oleshiv limestone deposit while calculating the energy absorption rates in the processes of processing non-metallic mineral raw materials.

Methodology. The authors of the paper sampled limestone in three outcropped locations of the Oleshiv mineral deposit. The degree of limestone purity in marketable products by type of fraction is examined using an X-ray DRON-3 diffractometer. The ultimate compressive strength of limestone is determined in laboratory conditions using a specialized test press KL 200/CE-Tecnotest. Energy absorption rates are calculated based on parameters characterizing the main stages of limestone processing, including crushing, transportation and screening.

Findings. The main trends in the field of limestone mining and processing have been analyzed, highlighting previously unresolved problems. On the example of processing limestone from the Oleshiv deposit, a technological scheme for its beneficiation has been developed; qualitative and quantitative parameters of the beneficiation process have been determined; the mineral composition of the fractional marketable product has been studied; the parameters of limestone compressive strength, as well as energy absorption rates in the processing processes to obtain finished products have been found.

Originality. The patterns of change in the flux limestone content during its beneficiation with preliminary dry extraction of marketable fractions of 80–130, 40–80 and 20–40 mm have been revealed. The patterns of the finished product yield distribution have been identified, taking into account the movement of clay-sand raw materials in the 0–20 mm fraction and its combination with the preliminary extraction of the 0–40 mm fraction before crushing. Based on mineralogical analysis of limestone composition by fraction types, it has been found that the degree of its purity increases from 85.54 to 94.0 %. The energy absorption rates during limestone processing have been determined, taking into account the physical-mechanical properties of the mineral and the parameters of equipment operation.

Practical value. A technological scheme for the beneficiation of limestone from the Oleshiv deposit has been developed, which allows for the production of seven fractions of limestone and one fraction of clay-sand raw materials. This scheme is optimized to maximize the extraction of the useful component, while ensuring high quality of the final product. The dynamics of energy absorption during limestone crushing, transportation, and screening has been determined, which makes it important to develop further recommendations for optimizing energy consumption in crushing processes.

Purpose. The purpose of the work is to establish the dependences of the levels of the protective potential of the system of protection of underground steel pipelines when approaching and/or crossing overhead power lines.

Methodology. To achieve the goal, the methods of the theory of equivalent electric circuits and the theory of the electromagnetic field, implemented in the packages of applied computer programs Matlab/Simulink and COMSOL Multiphysics, were used.

Findings. The spatial distribution in the soil of the induced electric field of the overhead power line in the direct location of the pipeline, which varies with a frequency of 50 Hz, was determined. The distribution of both constant and alternating voltage on the pipeline relative to the soil is given. An analysis of corrosion processes in the pipeline was carried out, on the basis of which the relatively safe flow of corrosion processes in the pipeline under the action of simultaneously occurring alternating current with a frequency of 50 Hz and direct current was investigated.

Originality. The scientific novelty of the work consists in determining the regularities of the influence of overhead lines on the nature of the distribution of the protective potential of cathodic protection stations with variable changes in the configuration of pipelines and laying conditions. The existence of significant deviations of the levels of the protective potential in the presence of a variable polyharmonic component of the signal is proven. On the basis of the study, it was established that under the accepted initial conditions, both criteria are unsatisfactory in some sections of the pipeline near the power transmission line.

Practical value. The practical significance of the research results is in determining the set of technical characteristics of the electrotechnical complex of protection against electrochemical corrosion, which allows ensuring the necessary levels of protective potential in the presence of a source of stray currents (overhead power lines).

Published: December 2024

Purpose. To investigate the linearised mathematical model of a heater and identify the potential for lowering the order of the heater’s transfer functions for further synthesis of control systems and improvement in the efficiency and safe operation of a track heater.

Methodology. After obtaining a linearised mathematical model of a heater with a transitory heat medium, the mathematical model equations are written in a standard format, followed by their Laplace transformation at zero initial conditions. With the help of the program product, an analytical study of the linearised model was performed, after which the Henkel singular values were used to simplify the order of the mathematical model transfer function from the seventh to the third and an assessment of the calculation accuracy loss after the function’s approximation was conducted, which showed that the accuracy loss was not significant.

Findings. Having studied the linearised mathematical models of heaters with a transitory heat medium, it was determined that the transfer functions in the mathematical model are of the seventh order, which significantly complicates the creation of an automated heater control system. As a result, a simplified mathematical model with transfer functions of the third order is obtained, which significantly reduces the calculation complexity on modern microprocessors.

Originality. Linearised mathematical models of an indirect heater were developed, based on the assumption of insignificant deviations of the output values from their baseline values. The studies of the linearised model showed that the transfer functions of the oil track heater are of the seventh order. Using Henkel singular values, it was possible to achieve transfer functions of the third order, which would reduce the complexity of creating automated control systems for indirect oil and gas condensate heaters.

Practical value. Modern digital control systems for the oil heating process are created. Using the method for reducing the order of transfer functions by using Henkel singular values to three significantly facilitates the integration of these models into microprocessor-based controls. This helps to improve the efficiency and reliability of automatic control systems, ensuring a stable and safe oil heating process, which is critical for the smooth operation of technological processes.
