In the present study, the authors have attempted to fabricate Polydatin encapsulated Poly [lactic-co-glycolic acid] (POL-PLGA-NPs) to counteract 7,12-dimethyl benzyl anthracene (DMBA) promoted buccal pouch carcinogenesis in experimental animals. The bio-formulated POL-PLGA-NPs were characterized by dynamic light scattering (DLS), Fourier transform infrared (FTIR) spectroscopy, X-ray powder diffraction (XRD) pattern analysis, and transmission electron microscope (TEM). In addition, the nano-chemopreventive potential of POL-PLGA-NPs was assessed by scrutinizing the neoplastic incidence and analyzing the status of lipid peroxidation, antioxidants, phase I, phase II detoxification status, and histopathological changes and in DMBA-treated animals. In golden Syrian hamsters, oral squamous cell carcinoma (OSCC) was generated by painting with 0.5% DMBA in liquid paraffin three times a week for 14 weeks. After 100% tumor formation was observed, high tumor volume, tumor burden, and altered levels of biochemical status were observed in the DMBA-painted hamsters. Intra-gastric administration of varying concentration of POL-PLGA-NPs (7.5, 15, and 30 mg/kg b.wt) to DMBA-treated hamsters assumedly prevents oncological incidences and restores the status of the biochemical markers. It also significantly enhances the apoptotic associated and inhibits the cancer cell proliferative markers expression (p53, Bax, Bcl-2, cleaved caspase 3, cyclin-D1). The present study reveals that POL-PLGA-NPs is a penitential candidate for nano-chemopreventive, anti-lipid peroxidative, and antioxidant potential, and also has a modulating effect on the phase I and Phase II detoxification system, which is associated with reduced cell proliferation and induced apoptosis in experimental oral carcinogenesis.

Published: September 2019

As software systems become increasingly large, the logic becomes more complex, resulting in a large number of bug reports being submitted to the bug repository daily. Due to tight schedules and limited human resources, developers may not have enough time to inspect all the bugs. Thus, they often concentrate on the bugs that have large impacts. However, there are two main challenges limiting the automation technology that would help developers to become aware of high-impact bug reports early, namely, low quality and class distribution imbalance. To address these two challenges, we propose an approach to identify high-impact bug reports that combines the data reduction and imbalanced learning strategies. In the data reduction phase, we combine feature selection with the instance selection method to build a small-scale and high-quality set of bug reports by removing the bug reports and words that are redundant or noninformative; in the imbalanced learning strategies phase, we handle the imbalanced distributions of bug reports through four imbalanced learning strategies. We experimentally verified that the method of combining the data reduction and imbalanced learning strategies could effectively identify high-impact bug reports.

Published: September 2019

Surface degradation of Ni-enriched layered cathode material Li[Ni0.6Mn0.2Co0.2]O2 (NMC622) is the main reason that leads to large capacity decay during long-term cycling. In the frame of this research, an amorphous SiO2 coating was applied onto the surface of the commercially available NMC622 powder by a wet coating process, through the condensation reaction of tetraethyl orthosilicate. The chemical composition of the coating layer was analyzed by inductively-coupled plasma. The morphology was studied by scanning electron microscopy and transmission electron microscopy. Electrochemical properties, including cyclic voltammetry, galvanostatic cycling, and rate capability measurements in a half-cell configuration, were tested to compare the electrochemical behavior of the non-coated and coated NMC622 materials. It is shown that the rate performance of the NMC622 materials is not affected by the coating layer. After 700 cycles in the range of 3.0–4.3 V at 2 C discharge, the cells with SiO2-coated NMC622 materials retained 80% of their initial capacity, which is higher than the uncoated ones (74%). Physicochemical characterizations, e.g., XRD and SEM, were performed post-mortem to reveal the stabilizing mechanism of the SiO2-coated NMC622 electrodes after long-term cycling. Based on these results, this is due to the shielding effect of the coating between the NMC622 particle surface and the liquid electrolyte, along with its scavenging effect on HF. SiO2 coating is therefore a facile surface modification method that results in potentially significant enhancement of the cyclic stability of Ni-rich NMC materials.
What Do We Know about the Use of EEG Monitoring during Equine Anesthesia: A Review
Authors: Drewnowska Olga , Lisowska Barbara , Turek Bernard
Published: September 2019

Electroencephalography is a noninvasive method used for the measurement of central nervous system bioelectrical activity. Besides its use for neurological disorders diagnostics in humans and animals, it was found to be useful as a part of the anesthetic monitoring. Introducing the electroencephalography (EEG) measurement intraoperatively in humans and in animals, due to its high specificity and sensitivity (limited number of wave patterns and high number of variabilities influencing them), with comparison to cardiovascular parameters might significantly increase the quality of anesthesia. The use of EEG during equine anesthesia may help to maintain a proper depth of anesthesia in this species. Due to the fact that EEG analyzers were designed for humans, there are still limitations of their use in horses, and different methods of analysis are studied. The paper introduces the physiology of EEG, its use in animals during anesthesia, and specification for horses.

Published: September 2019

The need to detect malware before it harms computers, mobile phones and other electronic devices has caught the attention of researchers and the anti-malware industry for many years. To protect users from malware attacks, anti-virus software products are downloaded on the computer. The anti-virus mainly uses signature-based techniques to detect malware. However, this technique fails to detect malware that uses packing, encryption or obfuscation techniques. It also fails to detect unseen (new) ones. This paper proposes an integrated malware detection approach that applies memory forensics to extract malicious artifacts from memory and combines them to features extracted during the execution of malware in a dynamic analysis. Pre-modeling techniques were also applied for feature engineering before training and testing the data set on the machine learning models. The experimental results show a significant improvement in both detection accuracy rate and false positive rate, 98.5% and 1.7% respectively, by applying the support vector machine. The results verify that our integrated analysis approach outperforms other analysis methods. In addition, the proposed approach overcomes the limitation of single path file execution in dynamic analysis by adding more relevant memory artifacts that can reveal the real intention of malicious files.
Tracheal Stenosis and Congenital Heart Disease in Trisomy 21
Authors: Kylat Ranjit I
Published: September 2019

Tracheal rings (TR) are rare, congenital cartilaginous defect of the upper airway and are usually due to complete or near complete circumferential cartilaginous tracheal rings, with variable degrees of tracheal stenosis (TS) and shortening. Chromosomal anomalies like trisomy 21 are characteristically associated with a wide range of upper airway anomalies including TS and congenital heart disease (CHD). However, the overall prevalence of severe forms of TS is rare and reported in 1.2% of all CHD patients. Herein, we present a rare association of severe TS due to complete tracheal rings in a trisomy 21 patient with CHD and the challenges in the management.
Novel Interaction Cost Analysis Applied to Bank Charges Calculator
Authors: Soukal Ivan
Published: September 2019

This paper presents an online calculator for bank charges, motivated by information asymmetry in the market for payment accounts. The calculator provides users with a personalized list of the most suitable bank accounts based on required services and monthly fee criteria. This paper outlines the conceptual foundation, workflows, and matrix of the data for the underlying logic of the calculator, as well as the design of the user interface. The proposed calculator was validated by performing an interaction cost analysis. This paper presents a novel methodology for conducting this analysis, including rules for expressing interactions in graphs for the objective evaluation of the usability of the user interface. Scenarios were defined and analyzed with the intended goal of choosing the best bank account. The interaction cost analysis then confirmed the differences in cost between traditional approaches (interacting with various web interfaces) and using a specialized online service (the calculator). The consistency of the layout and navigation contributed significantly to the final results being in favor of the proposed bank charges calculator. These conclusions are applicable not just within the selected market, but also in many others that are prone to problems arising from price information asymmetry.

Published: September 2019

We demonstrate a 3D printed holographic metasurface antenna for beam-focusing applications at 10 GHz within the X-band frequency regime. The metasurface antenna is printed using a dual-material 3D printer leveraging a biodegradable conductive polymer material (Electrifi) to print the conductive parts and polylactic acid (PLA) to print the dielectric substrate. The entire metasurface antenna is 3D printed at once; no additional techniques, such as metal-plating and laser etching, are required. It is demonstrated that using the 3D printed conductive polymer metasurface, high-fidelity beam focusing can be achieved within the Fresnel region of the antenna. It is also shown that the material conductivity for 3D printing has a substantial effect on the radiation characteristics of the metasurface antenna.
An Easy and Reliable Strategy for Making Type I Interferon Signature Analysis Comparable among Research Centers
Authors: Pin Alessia , Monasta Lorenzo , Taddio Andrea , Piscianz Elisa , Tommasini Alberto , Tesser Alessandra
Published: September 2019

Interferon-stimulated genes (ISGs) are a set of genes whose transcription is induced by interferon (IFN). The measure of the expression of ISGs enables calculating an IFN score, which gives an indirect estimate of the exposition of cells to IFN-mediated inflammation. The measure of the IFN score is proposed for the screening of monogenic interferonopathies, like the Aicardi-Goutières syndrome, or to stratify subjects with systemic lupus erythematosus to receive IFN-targeted treatments. Apart from these scenarios, there is no agreement on the diagnostic value of the score in distinguishing IFN-related disorders from diseases dominated by other types of cytokines. Since the IFN score is currently measured in several research hospitals, merging experiences could help define the potential of scoring IFN inflammation in clinical practice. However, the IFN score calculated at different laboratories may be hardly comparable due to the distinct sets of IFN-stimulated genes assessed and to different controls used for data normalization. We developed a reliable approach to minimize the inter-laboratory variability, thereby providing shared strategies for the IFN signature analysis and allowing different centers to compare data and merge their experiences.
A Deep Learning Model for Snoring Detection and Vibration Notification Using a Smart Wearable Gadget
Authors: Khan Tareq
Published: September 2019

Snoring, a form of sleep-disordered breathing, interferes with sleep quality and quantity, both for the person who snores and often for the person who sleeps with the snorer. Poor sleep caused by snoring can create significant physical, mental, and economic problems. A simple and natural solution for snoring is to sleep on the side, instead of sleeping on the back. In this project, a deep learning model for snoring detection is developed and the model is transferred to an embedded system—referred to as the listener module—to automatically detect snoring. A novel wearable gadget is developed to apply a vibration notification on the upper arm until the snorer sleeps on the side. The gadget is rechargeable, and it is wirelessly connected to the listener module using low energy Bluetooth. A smartphone app—connected to the listener module using home Wi-Fi—is developed to log the snoring events with timestamps, and the data can be transferred to a physician for treating and monitoring diseases such as sleep apnea. The snoring detection deep learning model has an accuracy of 96%. A prototype system consisting of the listener module, the wearable gadget, and a smartphone app has been developed and tested successfully.

Published: September 2019

Well stimulation using hydrochloric acid (HCl) is a common practice in carbonate reservoirs to overcome formation damage in the near wellbore area. Using HCl for matrix acidizing has many limitations at high-temperature (HT) conditions, such as tubulars corrosion and face dissolution due to the fast reaction rate. Chelating agents, such as L-glutamic acid-N,N-diacetic acid (GLDA), are alternatives to HCl to overcome these problems. We studied the effect of diluting GLDA in seawater on the reaction kinetics with carbonate rocks under HT conditions at low pH (3.8). Results of the reaction of carbonate at 1000 psi and 150, 200, and 250 °F with GLDA prepared in both fresh and seawater, GLDA/DI and GLDA/SW, respectively, are presented. The reaction kinetics experiments were carried out in HT rotating disk apparatus (RDA) at rotational speeds ranging from 500 to 2000 revolutions per minute (RPM) at a fixed temperature. Indiana limestone and Austin chalk were used to studying the effect of rock facies on the reaction of GLDA with rock samples. In both GLDA/DI and GLDA/SW, the reaction regime of 20 wt% GLDA (3.8 pH) with Indiana limestone was mass transfer limited. The reaction rate and diffusion coefficient were highly dependent on the temperature. For Austin chalk, at 200 °F and 1000 psi the diffusion coefficient of GLDA/SW is an order of magnitude of its value with Indiana limestone using the same fluid. Diffusion coefficients were used to estimate the optimum injection rate for stimulating HT carbonate formation and compared with coreflooding results. The data presented in this paper will support the numerical simulation of the acid flow in carbonate reservoirs.

Published: September 2019

Voltage collapse in power systems is still considered the greatest threat, especially for the transmission system. This is directly related to the quality of the power, which is characterized by the loss of a stable operating point and the deterioration of voltage levels in the electrical center of the region exposed to voltage collapse. Numerous solution methods have been investigated for this undesirable degradation. This paper focuses on the steady state/dynamic stability subcategory and techniques that can be used to analyze and control the dynamic stability of a power system, especially following a minor disturbance. In particular, the failure of one generator among the network with a large number of synchronous generators will affect other synchronous generators. This will become a major problem and it will be difficult to find or resolve the fault in the network due to there being too many variables, consequently affecting the stability of the entire system. Since the solution of large matrices can be completed more easily in this complex system using the Householder method, which is a small signal stability analysis method that is suggested in the thesis, the detection of error and troubleshooting can be performed in a shorter period of time. In this paper, examples of different rotor angle deviations of synchronous generators were made by simulating rotor angle stability deviations up to five degrees, allowing the system to operate stably, and concluding that the system remains constant.
Identification of Lithol Red Synthetic Organic Pigment Reveals the Cause of Paint Layer Degradation on the Lazar Vozarević Painting “Untitled” with Copper Plates

Published: September 2019

Out of a total of 56 paintings in the collection of the Lazar Vozarević Gallery in Sremska Mitrovica, only one Lazar Vozarević painting from 1961, titled “Untitled”, has been subject to atypical degradation that has resulted in damage of completely atypical appearance. Such a problem had never before been noticed in Yugoslavian paintings of the 20th century. Discolored areas were found in various locations on the paint layer of the painting “Untitled” (especially on the lower and central parts of the painting), which disturbed the visual experience of the artistic work. To discover the cause of this discoloration, the composition of the paint layer was investigated, with the assumption that the true cause of degradation was hidden therein. Moreover, this painting belongs to a specific period in Vozarević’s activity, characterized by the use of non-traditional painting materials. To identify pigments from the highly degraded painting “Untitled”, scanning electron microscopy coupled with energy dispersive X-ray spectrometry (SEM/EDS) and micro-Raman spectroscopy were applied. Lithol red, a synthetic organic pigment known to give paintings a red tone, was identified as the main reason for the painting’s degradation. Lithol red is not only highly light-sensitive but is also chemically unstable, toxic, and sensitive to heat.

Published: September 2019

With the rapid development of information processing technology and continuously evolving technological hardware and software, the scale of spatial data has grown exponentially. This has necessitated that stricter requirements be placed on the way data is processed. The traditional single-machine centralized data processing method is gradually being replaced by the network-based cloud geographic information system (GIS) mode. However, the information processing method of the business system in the existing spatial information network environment is difficult to expand, which limits the application of the business system. This paper proposes an on-demand and extended model for the GIS data processing procedure that considers the three-way separation of algorithm development, business processes, and the operational interface, and can implement an on-demand expansion of business processes by process modeling the business and task scheduling the workflow engine. This can expand the scope of business systems and improve the efficiency of business system construction.

Type 2 diabetes (T2D) is a metabolic disorder characterized by hyperglycemia and insulin resistance in which oxidative stress is thought to be a primary cause. Considering that mitochondria are the main source of ROS, we have set out to provide a general overview on how oxidative stress is generated and related to T2D. Enhanced generation of reactive oxygen species (ROS) and oxidative stress occurs in mitochondria as a consequence of an overload of glucose and oxidative phosphorylation. Endoplasmic reticulum (ER) stress plays an important role in oxidative stress, as it is also a source of ROS. The tight interconnection between both organelles through mitochondrial-associated membranes (MAMs) means that the ROS generated in mitochondria promote ER stress. Therefore, a state of stress and mitochondrial dysfunction are consequences of this vicious cycle. The implication of mitochondria in insulin release and the exposure of pancreatic β-cells to hyperglycemia make them especially susceptible to oxidative stress and mitochondrial dysfunction. In fact, crosstalk between both mechanisms is related with alterations in glucose homeostasis and can lead to the diabetes-associated insulin-resistance status. In the present review, we discuss the current knowledge of the relationship between oxidative stress, mitochondria, ER stress, inflammation, and lipotoxicity in T2D.
Precision Core Temperature Measurement of Metals Using an Ultrasonic Phase-Shift Method

Published: September 2019

Temperature measurement is one of the most important aspects of manufacturing. There have been many temperature measuring techniques applied for obtaining workpiece temperature in different types of manufacturing processes. The main limitations of conventional sensors have been the inability to indicate the core temperature of workpieces and the low accuracy that may result due to the harsh nature of some manufacturing environments. The speed of sound is dependent on the temperature of the material through which it passes. This relationship can be used to obtain the temperature of the material provided that the speed of sound can be reliably obtained. This paper investigates the feasibility of creating a cost-effective solution suitable for precision applications that require the ability to resolve a better than 0.5 °C change in temperature with ±1 °C accuracy. To achieve these, simulations were performed in MATLAB using the k-wave toolbox to determine the most effective method. Based upon the simulation results, experiments were conducted using ultrasonic phase-shift method on a steel sample (type EN24T). The results show that the method gives reliable and repeatable readings. Based on the results from this paper, the same setup will be used in future work in the machining environment to determine the effect of the harsh environment on the phase-shift ultrasonic thermometry, in order to create a novel technique for in-process temperature measurement in subtractive manufacturing processes.
Rapid Recruitment of Symbiotic Algae into Developing Scleractinian Coral Tissues
Authors: Bockel Thomas , Rinkevich Baruch
Published: September 2019

While the early acquisition of Symbiodiniaceae algae into coral host tissues has been extensively studied, the dynamics of the migration of algal cells into rapidly expanding coral tissues still lacks a systematic study. This work examined two Red Sea branching coral species, Pocillopora damicornis and Stylophora pistillata, as they were growing and expanding their tissue laterally on glass slides (January–June, 2014; 450 assays; five colonies/species). We measured lateral tissue expansion rates and intratissue dinoflagellate migration rates. Tissue growth rates significantly differed between the two species (with Stylophora faster than Pocillopora), but not between genotypes within a species. Using a “flow-through coral chamber” under the microscope, the migration of dinoflagellates towards the peripheral edges of the expanding coral tissue was quantified. On a five-day timescale, the density of the endosymbiotic dinoflagellate cells, presenting within a 90 µm region of expanding coral tissue (outer edge), increased by a factor of 23.6 for Pocillopora (from 1.2 × 104 cells cm−2 to 2.4 × 105 cells cm−2) and by a factor of 6.8 for Stylophora (from 3.6 × 104 cells cm−2 to 2.4 × 105 cells cm−2). The infection rates were fast (5.2 × 104 and 4.1 × 104 algal cells day-1 cm−2, respectively), further providing evidence of an as yet unknown pathway of algal movement within coral host tissues.
Cyclospora cayetanensis and Cyclosporiasis: An Update
Authors: Almeria Sonia , Cinar Hediye N. , Dubey Jitender P.
Published: September 2019

Cyclospora cayetanensis is a coccidian parasite of humans, with a direct fecal–oral transmission cycle. It is globally distributed and an important cause of foodborne outbreaks of enteric disease in many developed countries, mostly associated with the consumption of contaminated fresh produce. Because oocysts are excreted unsporulated and need to sporulate in the environment, direct person-to-person transmission is unlikely. Infection by C. cayetanensis is remarkably seasonal worldwide, although it varies by geographical regions. Most susceptible populations are children, foreigners, and immunocompromised patients in endemic countries, while in industrialized countries, C. cayetanensis affects people of any age. The risk of infection in developed countries is associated with travel to endemic areas and the domestic consumption of contaminated food, mainly fresh produce imported from endemic regions. Water and soil contaminated with fecal matter may act as a vehicle of transmission for C. cayetanensis infection. The disease is self-limiting in most immunocompetent patients, but it may present as a severe, protracted or chronic diarrhea in some cases, and may colonize extra-intestinal organs in immunocompromised patients. Trimetoprim-sulfamethoxazole is the antibiotic of choice for the treatment of cyclosporiasis, but relapses may occur. Further research is needed to understand many unknown epidemiological aspects of this parasitic disease. Here, we summarize the biology, epidemiology, outbreaks, clinical symptoms, diagnosis, treatment, control and prevention of C. cayetanensis; additionally, we outline future research needs for this parasite.
From Waste to Multi-Hybrid Layering of High Carbon Steel to Improve Corrosion Resistance: An In-Depth Analysis Using EPMA and AFM Techniques
Authors: Handoko Wilson , Pahlevani Farshid , Yao Yin , Privat Karen , Sahajwalla Veena
Published: September 2019

Corrosion resistance of steel has attracted substantial interest for manufacturing applications to reduce costs corresponding to part failures, unexpected maintenance, and shortening lifespan. Meanwhile, millions of tonnes of slag, non-recyclable glass, and automotive shredder residue (ASR) are discarded into landfills every year, polluting the environment. Combining these two major issues, we delivered an alternative solution to enhance corrosion resistance of high-C steel. In this research, utilisation of these wastes (which were chemically bonded into steel substrate) as sources for production of multi-hybrid layering—including the multi-phase ceramic layer, the carbide layer, and the selective diffusion layer—was successfully achieved by single step surface modification technology. High-resolution topographical imaging by SEM and chemical composition analysis in micron-volume by electron probe micro analyser (EPMA) were performed. Nano-characterisation by atomic force microscopy (AFM) using the PeakForce quantitative nanomechanical mapping (PF-QNM) method was conducted to define Young’s modulus value of each phase in detail. Results revealed improvement of corrosion resistance by 39% and a significantly increased hardness of 13.58 GPa. This integrated approach is prominent for economic and environmental sustainability, consolidating industry demands for more profits, producing durable, steel components in a cost effective way to reduce dependency on new resources, and minimising negative impacts to the environment from disposal of wastes to the landfills.
Vigilances et négligences
Authors: Livet Pierre
Published: September 2019

La négligence peut apparaître comme le dual de la vigilance. Nous montrerons que la relation est plus complexe, en étudiant différents sortes de négligence : le « neglect » , l’« inattentional blindness » et sa relation avec l’opposition focal/ périphérique et celle entre information attendue ou inattendue, la cécité au changement, celle au choix, et la négligence méta-cognitive de ces négligences. Nous envisagerons une explication évolutionnaire de ces négligences, liées à nos dynamiques d’action. Une conscience ouverte néglige la focalisation (source de négligence) mais implique aussi de négliger les inférences. Nous pourrions exploiter la diversité des négligences pour éviter de dépendre d’un seul type de vigilance.

Published: September 2019

Bu çalışmada hukuk ve muhasebe bilim dalı
bağlamında, hukuk fakültesi ders müfredatında muhasebe dersinin gerekliliği irdelenmiştir.
6102 Sayılı Türk Ticaret Kanunu’nun (TTK) genel gerekçesi beşinci paragrafında,
uluslararası piyasaların bir parçası olmak hedefi ortaya konulmuştur. Hedefe
ulaşmak için, finansal tabloların uluslararası standartlara göre düzenlenmesi
gerekliliğine yer verilmiştir. Buna göre, TTK’da finansal tablolar, ticari
defterler bölümünde 68 ilâ 81. maddeleri arasında ve Anonim Şirketler Dokuzuncu
Bölümünde, Şirketin Finansal Tabloları ve Yedek Akçeler başlığı altında 514 ilâ
528. maddeler arasında açıkça düzenlenmiştir. TTK’da muhasebeye ilişkin temel kurallar da yer almaktadır. Bununla
birlikte vergi hukukunda, ticari defterlerin neler olduğu, finansal tabloların
nasıl tutulacağı ve vergiye esas alınacak karın ne şekilde belirleneceğine
ilişkin kurallar bulunmaktadır. Ayrıca Hukuk Muhakemeleri Kanunu’nda ticari
defterlerin delil olarak kullanılmasına dair düzenlemeler mevcuttur. Bu kanunlarda
birçok düzenleme bulunmasına rağmen, ilgili derslerin bazılarında bu konuların
esası anlatılamamakta, bazılarında ise konular hiç işlenmemektedir. Muhasebe,
hukuk alanının dışında görülmektedir. Yapılan kanuni düzenlemeler muhasebe

ticari defterlerin neler olduğu ve tutulması konuları bulunmalıdır. İkinci
dönem “Genel Muhasebe II” dersi programa konulmalıdır. Bilanço, gelir tablosu,
kar dağıtım tablosu ve nakit akış tablosu bu dersin kapsamında ele alınmalıdır.
Ayrıca dördüncü sınıfta seçimlik ders olarak “Karın Hesaplanması ve Dağıtımı”

Günümüzde
ders kitapları öğrencilerin öğrenme sürecinde sıkça kullandıkları kaynakların
başında gelmektedir. Bu açıdan ders kitaplarının kullanım yoğunluğu göz önünde
bulundurulduğunda ister istemez etkililiği araştırılmaya değer bir konudur. Bu
araştırmada ortaokul öğrencilerinin deneyimlerine dayanarak sosyal bilgiler
ders kitaplarıyla ilgili bazı noktalardaki beklenen etkisi ele alınmıştır. Bir
ders kitabı çok yönlü özellikleri olan bir kaynaktır. Bu çalışmada ise sosyal
bilgiler ders kitaplarının kapak tasarımı, bireysel kullanım özelliği,
içeriğinin transfer edilebilmesi, araştırmaya yönlendirmesi ve multidisipliner
yapısına yönelik etkileri, öğrenci görüşlerine dayanılarak ortaya konulmuştur.
Bu çalışma nicel araştırma yöntemine uygun tarama deseni ile yürütülmüştür.
Adıyaman ilindeki merkez ortaokullarında öğrenim gören 5. 6. ve 7. sınıf
öğrencilerinden 837’si ile anket yoluyla veriler toplanmıştır. Elde edilen
veriler sınıf seviyesi, cinsiyet vb. değişkenlerle karşılaştırılarak
yorumlanmıştır. Veriler frekans ve yüzdelik hesaplamalar kullanılarak analiz
edilmiş ve tablolar halinde gösterilmiştir. Çalışmanın bulgularına göre
öğrencilerin, sosyal bilgiler dersinin içeriğiyle ilgili karşı karşıya
kaldıkları bilgi kaynakları içerisinde (öğretmen, ders kitabı, internet,
gazete, arkadaş, aile, televizyon, sınavlara yönelik kitaplar) ders kitabındaki
bilgileri güvenilir buldukları anlaşılmıştır. Ayrıca öğrenci görüşlerine göre
ders kitaplarının öğrenciler tarafından kendi başlarına kullanma açısından
yeterli olmadığı ortaya konulmuştur. Sosyal bilgiler dersini alan öğrencilerin
çoğunluğu dersin tarih ve coğrafya dersleri şeklinde ayrılmasına ise sıcak
bakmamışlardır.

pedagojik bilgisinin önemli olduğu, karakter olarak kibar, sevecen, arkadaş
canlısı ve olumlu bir kişiliğe sahip olmasının önemli olduğu ortaya
konulmuştur.
Peer Assessment in EFL Writing Classes
Authors: KIZIL Vedat
Published: September 2019

This article presents the findings of a
seven-week case study which set out to investigate the benefits of integrating
peer assessment into university level EFL writing classes and examine its
impact on students’ social skills. The study was carried out with 17 B1 English
proficiency level students studying at an English preparatory programme of a
foundation university. First, the students were introduced to using rubrics to
assess a written product. Then, each week after the students had composed a
writing, a paragraph for the first three weeks and an essay for the remaining
four weeks, they were asked to anonymously assess one of their friends’ writing
by using the relevant rubric and filling in the peer assessment form. In
addition, the students were interviewed in the 3rd week of the study
in order to capture their early impressions regarding what they liked most and
least about peer assessment as well as what they learnt from being an assessor
and being assessed. The same interview was conducted again on the last day of
the study to find out whether the participants changed their opinions. The
results revealed that students benefited from peer assessment activities as
they improved their understanding of the rubrics over time, which lead to more
quality writings; they felt more accountable not only for their own learning
but also that of their friends’, which promoted a cooperative learning environment
in which students offered quality feedback to each other; and finally they
improved their collaboration and problem-solving skills, which contributed to
their social skills which are in parallel with the needs of modern society and can
be utilised outside the school environment.

Repetition of the production process is a complex system consisting of elimination subsystems, that is, practically from four phases that are interconnected in terms of the impact of each other, but the entire production system must be manifested as one harmonious system. Production in this system is the first stage when the products are produced, which are then distributed and exchanged through the free market, so that in the end they are subject to the process of consumption in the appropriate form, but depending on the nature of the product. In such a system, the stages of production and consumption are the most important stages of the production process, while the role of other phases in terms of mediating the mentioned phases in a deterministic sense. As it is produced for consumers-in terms of consumption, then the process of production in society is dictated by the consumption itself. This practically means that consumption is always the basis and goal of production.

Many countries pay primary importance to tourism development. But besides the natural resources, human resources for the industry are also rated as 'raw material' or are predicted by experts as the most important factor that will be coped by the industry over the past decades and the next. It is not enough for a country to be rich in natural beauty in order to be a tourist destination. There should interact: better management, culture, tradition, welcoming, quality of service, etc. All these affect the evolution or development of natural resources that directly affect the economic growth of a country.Supporting the development of traditional economic branches has not brought any major effect on the ongoing development in Kosovo, so that enrichment of economic structure and the development of new branches provide an important opportunity for qualitative advancement of the economy and the entire Kosovo society. The purpose of this paper is to highlight some aspects which identify opportunities and the importance of providing tourism development in the growth and progress of the Kosovo society.The impact of tourism on the economy of various countries in the world is recognized and the positive effects are usually expressed based in the revenue that the country generates during a certain period. It means that while other countries are wondering what has happened to the development of tourism during the year, we still have to ask, will it happen or how will tourism development happen to us.Kosovo is now on the way out of the crisis as political, security, economic, social or other ones, which have dominated for years. Based on the principle that the country cannot have a sustainable future without economic development, but no sustainable economic development without stability, it is quite necessary to identify the factors that contribute to the sustainability of the country. One of the factors which may contribute to the rapid emergence of severe crises is the development of tourism.
