Authors: KÖK Şahin , KASAP İsmail
Published: December 2023

Bu çalışma ile Çanakkale İli’nde tarım alanlarına yakın olan Çardak Lagünü’ndeki afidofag syrphidlerin (Diptera: Syrphidae) belirlenmesi amaçlanmıştır. Örneklemeler 2020 yılının bahar ve yaz ayları boyunca gerçekleştirilmiştir. Çalışma sonucunda, sekiz farklı konukçu bitki üzerindeki Hemiptera takımı Aphididae familyasından yedi afit türü ile ilişkili, Syrphidae familyasındaki beş cins içerisinde toplam beş afidofag syrphid tespit edilmiştir. Tespit edilen türler arasında, beş konukçu afit türü ile ilişki olan Episyrphus balteatus (de Geer) en yaygın bulunan Syrphidae türü olmuştur. Diğer taraftan, Eupeodes corollae (Fabricius)’nin sadece bir konukçu afit türü ile ilişkili olduğu belirlenmiştir. Bu sonuçlar, tarım alanlarına oldukça yakın konumda olan lagün ve sulak alanlar gibi tarım dışı habitatların afidofag syrphidlerin varlığı açısından zengin bir potansiyele sahip olduğunu ortaya koymuştur. Sonuç olarak, bu verilerin afidofag syrphidlerin korunmasına ve tarımsal ürünlerdeki zararlı afitlerin biyolojik mücadelesinde daha etkin kullanımına katkı sağlayacağı düşünülmektedir.

Published: December 2023

Aim: The aim of this study is to determine the views and suggestions of nursing students attending different universities in Türkiye regarding disability-friendly nursing education.
Material and Methods: This convergent mixed methods design research was conducted between 1 May and 1 September 2020. The research sample consisted of 830 students studying in the nursing departments of 61 different universities. In order to collect the data for the study, the researchers created an online questionnaire asking nursing students questions about the disabled-friendly framework of the nursing education they received. The Chi-Square Test was used to compare the findings of students' views and thoughts on nursing education with some variables. The answers to the open-ended questions were analysed by content analysis.
Results: The study participants are women at the rate of 83.3%. It has been found that the state of having sufficient knowledge about nursing care for the health of persons with disabilities impacts the students' thinking that their nursing education is disabled-friendly (p <.001).
Conclusion: As a result of this research, most of the nursing students in Türkiye did not evaluate the education they received as disabled-friendly, and a large part of the students stated that they wanted to be educated on disability-related issues.

Understanding trophic interactions in a warming world by bridging foraging ecology and biomechanics with network science
Authors: Cuff Jordan Patrick , Labonte David , Windsor Fredric M
Published: December 2023

Climate change will disrupt biological processes at every scale. Ecosystem functions and services vital to ecological resilience are set to shift, with consequences for how we manage land, natural resources, and food systems. Increasing temperatures cause morphological shifts, with concomitant implications for biomechanical performance metrics crucial to trophic interactions. Biomechanical performance, such as maximum bite force or running speed, determines the breadth of resources accessible to consumers, the outcome of interspecific interactions, and thus the structure of ecological networks. Climate change-induced impacts to ecosystem services and resilience are therefore on the horizon, mediated by disruption of biomechanical performance and, consequently, trophic interactions across whole ecosystems. Here, we argue that there is an urgent need to investigate the complex interactions between climate change, biomechanics and foraging ecology to help predict changes to ecological networks and ecosystem functioning. We discuss how these seemingly disparate disciplines can be connected through network science. To illustrate the interplay between ecology, environment and mechanics, we present an empirical example using an ant-plant network; we then use this example to demonstrate how warming, bite force and trophic interactions can be integrated through network science, and what this will achieve. It is our hope that this integrative framework will help to identify a viable means to elucidate previously intractable impacts of climate change, with effective predictive potential to guide management and mitigation.
Assessing the damage: analyzing the impact of the COVID-19 pandemic on accelerometer-assessed 24-hour movement behaviors in Brazilian adolescents

Published: December 2023

Background: Although there is consistent evidence of unhealthy changes in the 24-hour movement behaviours when comparing pre-COVID-19 periods to the early stages of the pandemic, there is limited research on long-term changes among adolescents. This study aimed to analyze both between- and within-participant differences in accelerometer-assessed 24-hour movement behaviours by comparing cross-sectional and prospective data from the pre-COVID-19 period (August to December 2019) to the period following the reopening of schools for in-person classes in southern Brazil (August to December 2022). Methods: This is a repeated cross-sectional with a nested cohort study. The 24-hour movement behaviours (i.e., time spent in physical activity of light [LIPA] and moderate-to-vigorous [MVPA] intensities, sedentary behaviour [SB], and sleep time [SPT]) were assessed by processing raw accelerometer data derived from a 24-hour/7-day wrist-worn protocol. Compositional multilevel models were applied to compare the 24-hour movement behaviour composition between time points for both cross-sectional and prospective data. Self-reported sociodemographic characteristics were examined as potential moderators. Results: The cross-sectional and prospective samples comprised, respectively, 1276 (53% female, average age of 16.4 ± 1.1) and 249 (53% female, average age of 15.6 ± 0.8) participants. The 24-hour movement behaviour composition differed between time-points in the cross-sectional (p<0.001) and prospective samples (p<0.001). Differences from 2019 to 2022 were explained by lower MVPA (-3.3 and -5.4 min/day in cross-sectional and prospective analysis, respectively) and a higher SB (4.7 and 34 min/day in cross-sectional and prospective analysis, respectively). No significant differences were observed for LIPA and SPT. Conclusions: Differences in the 24-hour movement behaviour composition comparing the cross-sectional samples, although statistically significant, were considered trivial and unlikely to have a substantial practical impact. However, considerable differences were observed in the prospective analysis. Taken together, the results suggest that most of the observed changes over time were expected as a natural consequence of aging during high school, with only a small portion attributable to the residual impact of the pandemic.
Correct Conclusions from Fallible Medical Tests: A Tutorial with JASP
Authors: Kucharský Šimon , Wagenmakers Eric-Jan
Published: December 2023

Medical professionals, patients, students, and the public at large regularly need to interpret the outcome of medical tests. These tests are error-prone, however, and the fact that the outcome is positive (or negative) does not establish with certainty that the disease is present (or absent). The correct interpretation of the test outcome demands that Bayes' rule is used to combine the quality of the test (i.e., sensitivity and specificity) with available background information (i.e., disease prevalence). It is well known that people find it difficult to understand and apply Bayes' rule, and that the correct outcome is often at odds with intuition, especially when a test with good operating characteristics yields a positive result, but the disease is relatively rare. Less well known is that in practical application, the values of sensitivity, specificity, and prevalence are usually associated with considerable uncertainty. The correct interpretation of a medical test demands that this uncertainty is explicitly acknowledged and properly taken into account.To facilitate the correct interpretation of fallible medical tests we introduce the Binary classification module in the open-source software JASP. This module explains medical testing through a series of informative visualizations. The module also allows users to propagate uncertainty in sensitivity, specificity, and prevalence to derived measure of interest, such as positive predictive value. The module can be used both in teaching and in medical practice.

Field testing autogenic storage thresholds for environmental signals in the strata of the Mississippi River Delta, U.S.A.
Authors: MUKHERJEE UDITA , Straub Kyle
Published: December 2023

Sediments transported from source terrains to depositional sinks carry environmental signals, which may or may not be preserved in stratigraphy. Recently developed theory suggests storage thresholds for environmental signals are set by the internal dynamics of sediment transport systems. For the first time, we explore this theory by testing whether changes in relative sea level (RSL) of various scales produce detectable signals stored in field scale stratigraphy. This field test builds on results from physical experiments where identifiable stratigraphic signals of RSL change were only produced from RSL cycles with magnitudes and/or periodicities greater than the spatial and temporal scales of the internal dynamics of deltas. Published long term sedimentation rates and sea level reconstructions suggest that the Mississippi River Delta (MRD) should be a good place to study sea level signal storage thresholds. We use publicly available seismic volumes from NAMSS-USGS to study how and if signals of paleo-sea level change are stored in strata of the MRD, comparing strata of the late Miocene (LM) and early Quaternary (EQ). Comparison of the amplitude and period of cycles in these two time periods, constrained by micropaleontological data, predicts storage of RSL signals in EQ strata, but not in the LM strata. This is confirmed as we show that signals of larger amplitude EQ RSL cycles are preserved in the MRD, but smaller amplitude LM signals are not detectable. This study adds field scale observations that quantify the intermingling of stratigraphic products of internal dynamics with products of RSL change over geological timescales.
Are AI safety and AI ethics memetic rivals?
Authors: Friedrich Daniel
Published: December 2023

As the risks of artificial intelligence (AI) attract the spotlight of public attention, policy-makers turn to academia to indicate which problems to prioritize. While some argue they should first deal with the prospect of a global catastrophe (AI safety), others believe AI’s current social impact bears greater urgency (AI ethics). This has led some to express the concern that one or the other „diverts the public’s attention“. In this article, I sketch out the psychological landscape, in which these concerns arise as a logical reaction, but suggest that in the case of AI risks, they are misplaced. I ran a survey, in which students were asked regarding their attitudes towards the issues commonly labeled under „AI ethics“ and „AI safety“. The results suggest that when salience of AI safety is experimentally increased, people report higher support for solving the problems related to AI ethics. Secondly, the levels of concern for AI safety and AI ethics correlate positively. Therefore, in terms of public-facing communication, AI safety and AI ethics seem like memetic allies, rather than rivals.

The present study presents results of a collaborative registered replication of Griskevicius et al.’s (2010) findings from Experiment 1 conducted by 24 student groups from six countries (N = 3,774) investigating if pro-environmental behavior can be promoted by inducing status motives. Student projects were part of the Collaborative Replication and Education Project. Results of this large multi-site replication showed no evidence to support the hypothesis that pro-environmental behavior can be stimulated by inducing status motives. We performed several exploratory analyses to investigate whether extension variables (i.e., equating “green” choices with prosocial behavior, political beliefs, sampling methods, US vs. other countries, duration of data collection and gender) moderated the effect of status motives on pro-environmental choices, but our findings reproduced null results.
Towards a framework for understanding emotional responses to climate change
Authors: Freeston Mark H , Cross Emily-Rose , Gan Sean
Published: December 2023

While the notion of climate change anxiety has become well established and familiar over the last decade, it is increasingly clear from emerging literature of a more complex range of emotional responses to anthropogenic climate change. This position paper proposes a framework of both positive and negative emotional states that may help integrate some of the diverse threads within the literature, lead to further development of measures, and potentially better understanding the links between emotions and the range of behaviours from denial, to disinterest, to degrees of engagement, through to activism, and fundamental changes in lifestyle or life orientation.The emotional states first considered are understandably anxiety, and grief and loss, followed by two registers of moral injury, a construct that has both transgressed against (anger and betrayal) and transgressor perspectives (guilt and shame). Next considered are powerlessness, confusion, and disengagement. Finally, two positive emotional states are considered, namely hope and gratitude. For each state we first provide a dictionary definition, followed by how it is understood in general, then we provide some examples from the climate change literature, and conclude with synonyms or related terms that fall under the broader heading.We conclude with a brief reflection on the likely non-linear nature of climate change emotions. Exposure to climate change will inevitably continue, through extreme weather, habitat loss, and impacts on communities and ways of life, whether experienced personally or vicariously through the media. Some of these experiences may also include successes of specific actions, periods of respite, and positive changes at community, societal and governmental levels. It is proposed that different emotional responses to climate change will continue in response to future and constantly changing experiences.

Published: December 2023

Objectives: The main purpose of this study was to assess the urinary tract infection (UTI) in female patients and determine the extended spectrum of beta-lactamase producers among MDR isolates.
Methods: A three-month hospital-based cross-sectional study was conducted from Marchto April 2022 at the Microbiology laboratory of Alka hospital, Lalitpur. Following the standard protocol, urine samples were taken for culture and identification. Urine samples were cultured using a semi-quantitative approach and antimicrobial susceptibility test was performed by disc diffusion method.
Results: Out of 493 female urine samples examined, significant growth was found in 106 samples. The positive isolates belonged to 5 different species. Out of them E.coli (77.36%) was the major pathogens isolated followed by Klebsiella pneumoniae (6.61%), Klebsiella oxytoca and Pseudomonas aeruginosa (1.88%) as Gram negative bacteria. And the most common Gram positive bacteria was found to be Staphylococcus aureus (12.26%). The most effective drug for Gram negative isolates was Amikacin (93.396%) followed by Nitrofurantoin (91.505%). The least effective drug against Gram negative bacteria was found to be Cefexime (64.16%) and Amoxicillin (58.49%). And for Gram positive isolates Ceftazidime (100%) and Amikacin (100%) were the choice of drug showing high susceptibility. The least effective drug used against Gram positive isolates tends to be Cloxacillin (15.38%). Out of 106 isolates 63 were found to be multidrug resistant among which 31 of them were ESBL producers confirmed by cephalosporin/clavulanate double disc synergy method. The urinary tract infection was most common in the age group 20-30 (20.75%) followed by age group 30-40 (16.98%).
Conclusion: UTI was least common among age groups 0-10 and 80-90 years. Bacterial isolates causing UTI had variation in the antibiotic susceptibility pattern with resistance against commonly used antibiotics which is a serious concern.
A Study on the Quality of Education Services for Adult Learners in ‘Work First-then on College System’: Using Kano model and Timko customer satisfaction coefficient
Authors:   The Education Research Institute, Lee Su Kyoung
Published: December 2023

The purpose of this study was to identify the degree of educational service quality perceived by adult learners in ‘Work First-then on College System’ who are college students only for adult learners in the lifelong education system of the LiFE project, and to secure data to build and operate better education services in the future. To this end, the educational service quality was classified using the Kano model, and the satisfaction and dissatisfaction indexes were measured by calculating the quality factor index through Timko's customer satisfaction coefficient. The results of the education service quality research are as follows. Among the 26 questions in the 5 factors of tangibility, reliability, empathy, certainty, and reactivity, 14 questions were classified as Attractive quality and 10 questions were classified as O-dimensional quality. And two questions showed the same measurement value for Attractive quality and O-dimensional quality. In addition, all Customer Satisfaction Coefficients were classified as Attractive quality with Better index higher than Worse index. Attractive quality is a positive factor that can be amplified to the level of customer satisfaction when the service is satisfied. All 5 questions regarding confidence in teaching expertise, preparedness, technique, friendliness, and fairness were found to be attractive qualities. In addition, O-dimensional quality is a factor that leads to satisfaction when satisfied and dissatisfaction when not satisfied, and is frequently found in tangible factors. This confirmed that the external parts such as university facilities and equipment are elements that must be satisfied first. The results of this study are expected to be used as data to secure and improve the quality of educational services for adult learners, to secure admission resources for adult learners, and to create a competitive advantage.

The Effects of Manhood Threat on Negative Emotions and State Self-Esteem in Male University Students : The Moderation Effect of Manhood Stimulation
Authors:   The Education Research Institute, Jeong Ok Kyung , Kim Ji Hyeon
Published: December 2023

This study tried to investigate the moderating effect of manhood stimulation on the effects of manhood threat on negative emotions and status self-esteem in male university students. 62 male university students who voluntarily participated through online research institutes were pre-examined(gender role identity scale, multiple affect adjective check list, state self-esteem scale), and then randomly assigned to one of the two groups divided into a shortened version of the movie 300(manhood stimulation group) or a video of the birth of the earth(gender neutral group). After watching the video, all participants were manipulated to experience the threat of manhood by providing feedback that femininity was higher than average as a result of the pre-test for gender role identity. After the threat experience, a post-test was conducted to verify the interaction between pre-post groups, and repeated measurement variance analysis was performed. The results of this study are as follows. Regarding the negative emotion of anger, the group that was stimulated with manhood showed a greater amount of change between pre-post test results than the gender neutral group. In terms of state self-esteem, the difference between pre-post tests was statistically significant in the group stimulated with manhood. The manhood stimulation group was found to have a moderating effect of interacting with manhood threats to increase anger emotions and to increase state self-esteem as a defensive response. The significance of this study will serve as the basis for revitalizing research considering precarious manhood properties and will help in effective intervention in male gender role counseling and education.

Published: December 2023

La anemia durante la gestación es considerada un problema de salud pública debidoa las prevalencias alarmantes que se presentan a nivel mundial. La medida optada porlos diversos gobiernos es la administración masiva con suplementos de hierro. Sinembargo, actualmente existe evidencia contradictoria sobre el consumo de hierro,el exceso de su consumo y los potenciales riesgos durante la gestación tanto parala madre como para el producto. Para la gestación se requiere de 1 gramo adicionalde hierro para la madre, el feto, la placenta y el parto. Esto genera un aumento de lamasa roja del 20%; pero, para evitar la hemoconcentración el volumen plasmáticose expande casi el 50%, generando una hemodilución fisiológica. Para la gestanteno se ha establecido un criterio que permita diferenciar la anemia por deficiencia dehierro, de la anemia fisiológica debido al proceso normal de hemodilución. En el casode Perú y de países con población residente de altura, se suma una problemáticaadicional, el factor de corrección de hemoglobina por residencia en la altura, el cuales un valor determinado de forma matemática y arbitraria. Las evidencias recientessugieren que este factor debe ser reevaluado, debido a que no considera la etnia yel tiempo generacional de residencia en la altura. La presente revisión muestra unaactualización y discusión de los criterios de diagnóstico de anemia, la suplementacióncon hierro, el factor de corrección de hemoglobina por altura de residencia y elimpacto de la contaminación ambiental sobre el proceso de gestación.

La úlcera péptica es menos frecuente en las embarazadas que en las mujeresno gestantes. Aunque rara vez se perfora durante el embarazo y aún menosfrecuentemente durante el puerperio, está asociada con mayor riesgo de muertematerna. El uso de analgésicos no esteroideos y la infección por Helicobacter pyloriestán relacionados con su patogénesis. Debido a sus características clínicas duranteel embarazo, la sepsis puerperal e íleo paralítico pueden retrasar el diagnóstico.Luego del parto, signos clínicos como taquicardia de reciente aparición, dolorabdominal y el aumento de la distensión deben sugerir el diagnóstico. Dado quelas complicaciones pueden provocar morbilidad y mortalidad significativas duranteel puerperio, la detección precoz y el tratamiento rápido son imperativos. Eltratamiento de la úlcera péptica perforada durante el puerperio es el mismo queel de una situación quirúrgica abdominal urgente. Una reparación satisfactoria conparche omental suele sellar el defecto y evitar nuevas perforaciones. Se presenta uncaso de úlcera péptica perforada durante el puerperio.

DECISION USEFULNESS AND INFLATION ACCOUNTING: THE CASE OF TURKEY
Authors: SELİMEFENDİGİL Seyfullah
Published: December 2023

The purpose of this study is to examine the issue of inflation accounting and decision useful-ness. As well as having political costs for a country, inflation has financial costs for compa-nies and their stakeholders. To test the necessity of inflation accounting adoption, Ohlson's (1995) pricing model is used and earnings volatility is measured across years. It was con-cluded that earnings are more volatile and don’t explain the changes in company market val-ue when inflation adjustments are required. Furthermore, it has been suggested that steward-ship theory can explain the reporting of inflation-adjusted values in conjunction with histori-cal cost values.

Published: December 2023

Hoods are the most important devices used in our kitchens that contribute to the ventilation of the environment. 95% of the electric motors used in hoods are single-phase asynchronous motors. There are many domestic and foreign electric motor manufacturers producing for the hood industry. Supplier selection in companies producing hoods is vital and critical for sustainable production. It is extremely important to make the right decision in the purchasing process of the supplied products. While the decisions taken can sometimes be clearly separated from each other, sometimes they can be intertwined and interconnected. Multi criteria decision making techniques are used when making decisions that cannot be clearly separated or explained with numerical data. The aim of this study was to determine the most suitable Supplier for the built-in appliance company operating in the Turkiye/Amasya region by using fuzzyTOPSIS method in the supply of 1-phase asynchronous motors used in hoods. After 5 experts working in the company were determined as decision makers, 4 criteria were determined: quality, system capacity, finance and logistics performance. The best supplier selection among 6 different suppliers was made using this method. For the first time, a solution proposal was presented with the fuzzyTOPSIS technique for the 1-phase induction motor supplier selection and a contribution was made to the literature.

Sıvı kristallerin ekran teknolojisi, sensör, esnek devre elamanları, ışık modülatörleri gibi uygulamalarda kullanılabildiği bilinmektedir. Kolesterik mezofaz sıvı kristaller ışığın seçici geçirgenlik özelliği ile ön plana çıkmaktalardır. Bu çalışmada, ilk defa tek-iğneli elektro-eğirme kullanılarak kolesterik sıvı kristaller-polimer kompozit liflerinin üretilmiş ve incelenmiştir. Bu bağlamda ilk olarak, mavi, yeşil ve kırmızı renkte ışığı yansıtabilecek sırasıyla 470 nm, 550 nm ve 640 nm spiral adım uzunluklarına sahip kolesterik sıvı kristaller hazırlanmıştır. Konak nematik mezofaz olarak E-7 ve yüksek burma gücüne sahip R-5011 kiral katkı maddesi kullanılmıştır. Bu kolesteriklerin yaklaşık istenilen adım uzunluklarına sahip oldukları UV-VIS spektrofotometre ölçümleri ile gösterilmiştir. Ayrıca, hazırlanan kolesteriklerin karakteristik bir tekstür olan oily-streak desenlere sahip olduğu görülmektedir. Bu kolesterikler poliakrilonitril ile karıştırılarak dimetilformamid içerisinde çözdürülmüştür. Bu çözeltiler tek-iğneli elektro-eğirme sistemi ile 16 kV, 18 kV, 20 kV, 22 kV ve 24 kV uygulama voltajları altında eğirilerek sıvı kristal polimer kompozit lifleri haline getirilmişlerdir. Eğirilen liflere katkılanan kolesterik sıvı kristallerin varlığı optik ve yapısal analizler geçekleştirilerek belirlenmiştir. Polarize optik mikroskop ile yapılan görüntülemelerde çapraz polarizörler arasındaki lifler boyunca parlamalar gözlenmiştir. Bu parlamalar lif boyunca sıvı kristallerin yerleştiğini göstermektedir. Ayrıca, yapısal analiz sonucu her bir lifte üretim parametreleri ve katkı maddelerine göre lif yapısının değişimi üzerine çalışma yapılmıştır. Tüm kolesterik örnekleri için düşük uygulama voltajlarında eğirilen lifler boyunca uzanan küresel boncuk yapılar tespit edilmişken daha yüksek uygulama voltajlarında eğirilen liflerde boncuk yapılar oldukça seyrek gözlenmiştir. Kızılötesi spektroskopisi analizleri sonucu liflerin sıvı kristallerin sergilediği titreşim pikleri ile aynı dalga sayılarında pikler vermesi lif yapılarında sıvı kristallerin varlığını göstermiştir.

Authors: TEPE Tolga Kağan
Published: December 2023

The effect of ethanol pretreatment on the drying characteristics, color properties, shrinkage ratio and comparison of thin layer and artificial neural network (ANN) were investigated in the current study. Ethanol pretreatment increased drying rate and reduced drying time. In addition to this, ethanol concentration and pretreatment time had positive contribution to drying rate. According to the statistical parameters, ANN modeling showed better performance in the prediction of moisture ratio of the banana samples in comparison to thin layer modeling. On the other hand, color properties were negatively affected by drying and ethanol pretreatments. L* and b* values decreased whereas a* values of the banana samples showed increment tendency. Also, total color difference (∆E) was found to be higher than 5 value, indicating that non-trained observer notices the color change. Besides, it is obviously that ethanol pretreatment affected shrinkage ratio of the banana samples. Especially, diameter shrinkage ratio increased with the increment of ethanol concentration and pretreatment time.

Bu çalışmada, Momordica charantia L. etanol ekstraktının (ME) farklı konsantrasyonları (% 0.25, 0.50, 0.75 ve 1) kullanılarak metilselüloz yenilebilir filmler (MC) üretilmiştir. MC filmlerin fizikokimyasal özellikleri ile antimikrobiyal (Bacillus cereus, Escherichia coli ATCC 25922, Staphylococcus aureus 6538 IP, Staphylococcus epidermis ATCC 1228, Vibrio parahemolyticus ATCC 17802, Yersinia pseudotuberculosis ATCC 911, Listeria monocytogenes, Enterococcus faecalis ATCC 29212, Salmonella Typhimurium ATCC 14028, Klebsiella pneumonia, Proteus vulgaris ATCC 13315'e karşı) ve antioksidan aktiviteleri açısından analizleri yapılmıştır. Fourier dönüşümlü kızılötesi (FTIR) spektroskopisi analizi, polimer ve ME arasındaki fonksiyonel grup etkileşimlerini belirlemede kullanılırken, termal gravimetrik analiz (TGA) ve diferansiyel taramalı kalorimetri analizi ise fizikokimyasal karakterizasyonu tanımlamada kullanılmıştır. Kontrol filmlere kıyasla, 24 saat sonunda en yüksek antimikrobiyal etki Proteus vulgaris'e karşı (yaklaşık 1.93 log KOB/mL) %1 ME içeren MC filmlerinde elde edilmiştir. ME konsantrasyonunun artması ile film mukavemeti arasında ters bir ilişki gözlemlenirken, su buharı geçirgenlik değerlerinde önemli bir azalma, temas açısı değerlerinde iyileşme ve hidrofilik özelliklerde belirgin bir artış tespit edilmiştir. Tüm bu sonuçların ışığında, MCME film örnekleri biyolojik olarak parçalanabilir özellikte ve yenilebilir gıda ambalajlama uygulamaları için uygun bileşenler olarak nitelendirilmiştir.

Bu çalışmada iki bölgeli ara ısıtmalı termal güç sisteminde yük frekans kontrolü için kesir hesabına dayalı farklı denetleyici tasarımları gerçekleştirilmiştir. İki bölgeli ara ısıtmalı termal güç sistemi için doğrusal model oluşturulmuş, bu model için iki farklı yük değişimi göz önüne alınmış ve dört farklı denetleyicinin performansları gözlemlenmiştir. Çalışmada tasarımı yapılan ve incelenen denetleyiciler, oransal-integral-türev (PID), eğimli-integral-türev (TID), filtreli eğimli-integral-türev (TIDF) ve kesirli filtreli eğimli-integral-türev (TIDFF) denetleyicilerdir. Denge optimizasyon algoritması kullanılarak, hata tabanlı performans metriklerinden biri olan zaman ağırlıklı mutlak hatanın toplam değerini minimum seviyeye çeken denetleyicilerin tasarımı gerçekleştirilmiştir. Tasarlanan denetleyicilerin kullanılmasıyla ile elde edilen bağlantı hattı gücü değişim grafikleri ve frekans değişimi grafikleri bulgularda verilmiş ve bu grafikler üstünden elde edilen oturma zamanı, alt aşma ve üst aşma değerleri tablolar ile karşılaştırmalı olarak sunulmuştur. Kesir hesabına dayalı denetleyicilerin (TID, TIDF ve TIDFF), geleneksel PID denetleyicilerden daha verimli olduğu görülmüştür.

O artigo retrata um estudo no qual se cotejou as experiências escolares, tendo em vista seus efeitos para constituição da docência. Pari passu averiguou-se o contato com a Matemática/Geometria na escolarização. Tratou-se de uma pesquisa qualitativa, sob uma abordagem narrativa. Enquanto procedimento para a coleta das fontes orais empregou-se entrevistas semiestruturadas e a triangulação na qualidade de método para análise dos dados. Contou-se com a participação de 12 pedagogas. A iniciativa (epistêmica) facultou compreender, em síntese, a existência de uma variação de idade significativa entre as participantes. Além disso, os dados encontrados refletiram a tendência à feminilização do magistério. Constatou-se, ademais, cuja maioria das entrevistas serem provenientes do ensino público, com algumas exceções. Ao descreverem o processo de escolarização, fica manifesto corresponder a uma perspectiva tradicional de ensino. Por outro lado, alguns projetos didáticos somados a algumas ações afetivas relatadas, foram capazes de mitigar os efeitos contraproducentes de um ensino conteudista. Depreendeu-se ainda, a existência de uma expressiva rejeição em relação à matemática. Relativo à experiência escolar relacionada à geometria, verificou-se à ausência de lembranças concernentes ao conhecimento geométrico.
