Authors: Tecir Elif Tuğçe
Published: June 2024

Toplumlar kendi kültür tarihleri içerisinde doğadan ve çevrelerinden gördükleri birçok şeyi tasvir edip, bunlara sembolik anlamlar yüklemişlerdir. Bu tasvirler, göçebe-bozkır kültürü ile yaşayan toplumlarda, güçlü bir hayvan kültü ile geliştirilmiş ve mimariden, el sanatlarına birçok alanda eserler verilmiştir. Çift başlı kartal motifi, Orta Asya ve Mezopotamya’ya dayanan, farklı coğrafyalarda ve farklı kültürlerde yer edinerek halen günümüzde kullanılması ile dikkat çekmektedir. Çift başlı kartal tasviri, kartaldan türetilmiş ve aynı anlamlar ile kullanılmıştır. Yeterince sorgulanmadan, doğrudan Selçuklulara atfedilen bu motif, aksine Selçuklulardan önceki yüzyıllarda da görülmektedir. Neredeyse her uygarlığın benimsediği hayali varlık, ortak değere dönüşerek nesilden nesile taşınarak, milli bir kimlik kazanmıştır. Tekstil sanatlarında; içinde dokuma kumaş, halı, kilim, giysi süsleri tekstil aksesuarları gibi taşınması rahat, kolay ve ticari değere sahip ürünlerde kullanılması nedeniyle, bu motifin, farklı kültürlere geçişinde yaygınlık sağlanmıştır. Çalışma kapsamında, çift başlı kartal motifinin tekstil sanatları, dokuma kumaş ve halı örnekleri üzerinde görülen ikonografisi, dokuma kumaşlardaki kompozisyon kurgusu ve motif çeşitliği teknik çizimler ile detaylandırılmıştır. Çift başlı kartal motifinin tekstil sanatlarındaki yeri, örnekleri, tasvir özellikleri araştırılmış olup sekiz adet kumaş görseli üzerinden incelemeler yapılmıştır. Halı dokumalarında beş adet örnek üzerinden motif incelenmiştir. Toplamda 13 örnek üzerinden motif çeşitliliği teknik çizimleri ile açıklanmıştır. Çift başlı kartal motifinin kumaş ve halı dokumaları üzerindeki bulguları sonuç bölümünde değerlendirilmiştir.

ÖZ: Doğu Karadeniz Bölgesi’nde yaşayan insanların temel geçim kaynaklarının önemli bir kısmını tarımdan elde edilen gelirler oluşturur. Bunun yanında bölgede yaşayan insanlar ektikleri tarım ürünleriyle yıllık yiyecek ihtiyacının bir bölümünü karşılamaya çalışır. İnsanlar tarım ürünlerinden oluşan bahçelerini ekim zamanından hasat vaktine kadar takip eder. Ancak tarım ürünlerini yabani hayvanlar tahrip ederek ciddi zararlar verir. Doğu Karadeniz Bölgesi, yaban hayatı açısından zengin bir alandır. Bölgede; ayı, çakal, domuz, köstebek, porsuk, sincap, fare, ceylan, geyik, karaca gibi yabani hayvanlar tarım alanlarına girerek tarım ürünlerini talan eder. Ayrıca böcek ve kuş türleri de bahçedeki ürünlere, meyvelere dadanarak ürün kaybına yol açar. Bundan dolayı bölgede tarımla uğraşan kişiler yabani hayvanların ürünlere zarar vermemesi için kendilerince birtakım yöntemler geliştirirler. Yabani hayvanları kaçırmak amacıyla bahçelerin kenarlarına halkın kendi bilgi ve tecrübelerine dayalı olarak oluşturdukları halk teknolojisi ürünleri yaparlar. Bahçelere yapılan düzenek ve tuzaklarla hayvanlar kaçırılmaya çalışılır. Bahçelerin içinde ve çevresinde yapılan kaçırma yöntemleriyle hayvanların bahçeden uzaklaşması hedeflenir. Bu çalışmada konuyla ilgili bilgiler yazılı kaynaklar içerisinden taranmıştır. Doğu Karadeniz Bölgesi’nde tarım alanlarını yabani hayvanlardan korumak için yapılan uygulamalar değerlendirilmiştir.

Authors: Kayabaşı Rabia Gökcen , Çini Ömer
Published: June 2024

Kültür, topluluk hâlinde yaşayan insanların; her türlü uygulama, tören, âdet, sanat, dil, düşünce, inanış ve yaşayış tarzı vb. öğelerin bütünü demektir. Kültür, nesilden nesile aktarılarak günümüze kadar ulaşmıştır. İçinde yaşadığımız toplumun yapısında yer alan bu öğeler kullanılır, ancak neden böyle bir uygulama yapıldığının sebebi genellikle araştırılmaz. Bu kültür unsurlarından inanç, halk arasında daha yaygın ve unutulmaya dirençlidir. İnançlar, bir toplumun gelenekleri ve göreneklerinden meydana gelmiş uygulamalardır. Bu inanışlar hastalıkları sağaltmada, yağmur yağdırmada, bir iş için yolculuğa çıkma vb. çeşitli alanlarda görülmektedir. İnsan, doğası gereği toprak ve tabiat ile iç içe olmuştur. Bolluk ve bereket için yağmur duaları düzenlenmiştir. Aksaray/Yenikent yöresindeki yağmur törenleri ise bu duruma örnek teşkil etmektedir. Bu törenlerde hayvanlara toplum tarafından yüklenen bazı özellikleri gereği bu uygulamalarda yerini almıştır. Kurbağada bu hayvanlardan birisidir. Kurbağa, halk hekimliğinde kullanılmıştır. Kurbağalara, ateş ve suyla ilgili olan birçok törende de rastlamak mümkündür. Bu bakımdan ateşin ve ayın temsilcisi olduğuna inanılan kurbağaların kutsal bir ruh taşıdığına inanılmıştır. Yağmur yağdırma törenlerinde de “yada taşı” olarak görülmektedir. Türklerin atlı-göçebe hayat tarzı, ekonomik ve sosyal hayatlarında hayvanların etkili bir unsur olmasına zemin hazırlamıştır. Bu nedenle hayvan kültü Türk toplumunda büyük bir yer edinmiş olup günümüzde de etkilerini sürdürmektedir. Bu çalışmada kurbağa; halk hekimliği, yağmur duaları, hastalıkları sağaltma, taşıdığı kutsal ruh, “yada taşı”, ay, güneş ve ateşle ilişkisi gibi konular açısından kült merkezli bir bakışla incelenmiştir.

Introduction: Aneurysmal bone cyst is a benign, most often non-neoplastic lesion affecting the bone. Malignant transformation is reported in certain cases, although rare. It commonly occurs in young adults with around 75% of the cases occurring in the first two decades and 95% occurring in the first 3 decades. The management depends on the individual case parameters with ABC occurring in a weight-bearing area of a bone warranting an aggressive treatment plan with the consideration of preventing a pathological fracture. Case Report: A 20-year-old male patient with no other comorbidities presented to us with complaints of atraumatic right hip pain of 9-month duration. On preliminary clinical examination and imaging studies with X-rays, CT scan, and MRI, the patient was diagnosed to have an aneurysmal bone cyst (ABC) of the right proximal femur. The patient was operated with intra-lesional excision with extended curettage and prophylactic fixation with DHS plating and kept on yearly follow-up. 10-year follow-up showed complete resolution of the lesion and implant removal was done after that. Conclusion: As is clear from this case, the treatment of an aneurysmal bone cyst needs to individualized based on the patient’s age, complaints, and tumor behavior in terms of its aggressiveness, size, and its extent. Often, en bloc excision with extensive curettage is required along with bone grafting and prophylactic fixation to support the bone graft and to prevent a pathological fracture and further recurrence. Implant removal if indicated should be done after complete resolution of the lesion, patient willingness, and any other medical indication. Keywords: ABC, DHS, en bloc excision, extended curettage, pathological fracture, implant removal.

Introduction: Aneurysmal bone cysts (ABCs) are aggressive and benign tumors that primarily affect children and adolescents. The standard course of treatment for ABCs involves surgical excision or curettage with a bone transplant or cement to repair the deficiency. Denosumab, a monoclonal antibody that inhibits receptor activator of nuclear kappa B ligand, is used to treat osteoporosis, skeletal metastasis, and giant cell tumors of the bones. Case Report: This case study details the therapeutic treatment of a female patient, age 22, who had a recurring aggressive ABC of the distal tibia. The patient was initially treated using curettage and lesion filling. However, recurrence of the osteolysis was observed 9 months later that led to subsequent interventions involving absolute alcohol sclerotherapy in multiple sessions. However, these interventions failed to achieve ossification. Following unsuccessful surgical and sclerotherapy treatments, the patient was administered denosumab, which led to a positive response. Regular radiographic and clinical follow-up demonstrated significant improvements in ossification and pain reduction. During the course of the 12-month treatment, the frequency of visits was gradually reduced. Further, follow-up and monitoring revealed the effectiveness of the local control and long-term treatment. Conclusion: This case report highlights the ability of denosumab to manage recurrent aggressive ABCs after surgical or sclerotherapy failure. Keywords: Aneurysmal bone cyst, curettage, distal tibia, denosumab, recurrence, sclerotherapy.
Impact of Agricultural Financing on Agricultural Growth Sustainability in Nigeria
Authors: Okunlola Olalekan Charles , Ayetigbo Olumide Abiodun
Published: June 2024

ABSTRACT: Agricultural financing plays a crucial role in enhancing agricultural productivity, profitability, and sustainability. These factors are essential for achieving food security, reducing poverty, and promoting economic growth in developing countries, such as Nigeria. However, agricultural financing faces various challenges, including high risks, low returns, inadequate infrastructure, weak institutions, and limited access to formal financial services. This study aims to examine the impact of agricultural financing on agricultural growth sustainability in Nigeria from 1985 to 2021, taking into account both domestic and international perspectives. Domestic agricultural financing is measured through commercial bank loans, interest rates, and the Agricultural Credit Guarantee Scheme Fund, while international financing is measured through agricultural foreign direct investment. The study utilizes the ARDL bonding test to analyze the short- and long-term effects of agricultural financing on agricultural growth sustainability in Nigeria. The findings of this study reveal that agricultural financing has both short-term and long-term impacts on agricultural growth sustainability. Domestic financing of agriculture significantly influences agricultural growth sustainability in Nigeria. Bank credit to the agricultural sector stimulates agricultural GDP. Similarly, the interest rates set by banks exhibit a negative relationship with agricultural growth sustainability in Nigeria, both in the short and long term. On the other hand, the Agricultural Credit Guarantee Scheme Fund (ACGSF) positively affects Nigeria's agricultural GDP in both the short and long term. However, international financing adversely affects agricultural GDP in the long run in Nigeria. The negative impact of foreign direct investment on agricultural output may be attributed to increased competition and conflicts over land and resources as foreign investors seek to secure large-scale and long-term land deals, often with the support or involvement of the host government. The significance of this study lies in its contribution to the existing literature on the influence of agricultural financing on agricultural growth sustainability, providing valuable insights for policymakers, researchers, and stakeholders interested in advancing the agricultural sector. By considering both domestic and international perspectives, this study assists the government and policymakers in effectively managing agricultural financing to stimulate agricultural growth and ensure sustainability for overall development.

Published: June 2024

Conversion from free-space waves to surface plasmons has been well studied as a key aspect of plasmonics. In particular, efficient coupling and propagation of surface plasmons via phase gradient metasurfaces are of great current research interest. Hereby, we demonstrate a terahertz metacoupler based on a bilayer bright–dark mode coupling structure attaining near-perfect conversion efficiency (exceeding 95%) without considering absorption loss of the materials and maintaining a high conversion level even when the area of the excitation region changes. To validate our design, a fabricated metacoupler was assessed by scanning near-field terahertz microscopy. Our findings could pave the way for developing high-performance plasmonic devices encompassing ultra-thin and compact functional devices for a diverse range of applications, especially within the realm of high-speed terahertz communications.

Published: June 2024

The embedded ultra-precision displacement measurement is of great interest in developing high-end equipment as well as precision metrology. However, conventional interferometers only focus on measurement accuracy neglecting the sensor volume and requirement of embedded measurement, thus hindering their broad applications. Here we present a new sensing method for realizing large-range displacement measurement in narrow space scenarios based on the combination of a fiber microprobe interference-sensing model and precision phase-generated carrier. This is achieved by microprobe tilted-axis Gaussian optical field diffraction and high-order carrier demodulation to realize large-range displacement sensing. It is uncovered that the microprobe element misalignment and phase demodulation means play pivotal roles in the interference signal and the accuracy of large-range displacement sensing. The analysis shows that the proposed interference-sensing method can effectively reduce the nonlinearities. Experimental results illustrate that the measurement range extends from 0 to 700 mm. Furthermore, the maximum nonlinear error is reduced from tens of nanometers to 0.82 nm over the full range, allowing subnanometer accuracy for embedded measurements in the hundreds of millimeters range.

Breast cancer is the most prevalent malignancy and the most significant contributor to mortality in female oncology patients. Potassium Two Pore Domain Channel Subfamily K Member 1 (KCNK1) is differentially expressed in a variety of tumors, but the mechanism of its function in breast cancer is unknown. In this study, we found for the first time that KCNK1 was significantly up-regulated in human breast cancer and was correlated with poor prognosis in breast cancer patients. KCNK1 promoted breast cancer proliferation, invasion, and metastasis in vitro and vivo. Further studies unexpectedly revealed that KCNK1 increased the glycolysis and lactate production in breast cancer cells by binding to and activating lactate dehydrogenase A (LDHA), which promoted histones lysine lactylation to induce the expression of a series of downstream genes and LDHA itself. Notably, increased expression of LDHA served as a vicious positive feedback to reduce tumor cell stiffness and adhesion, which eventually resulted in the proliferation, invasion, and metastasis of breast cancer. In conclusion, our results suggest that KCNK1 may serve as a potential breast cancer biomarker, and deeper insight into the cancer-promoting mechanism of KCNK1 may uncover a novel therapeutic target for breast cancer treatment.

Background

Pathogens can impact host RNA modification machinery to establish a favorable cellular environment for their replication. In the present study, we investigated the effect of Toxoplasma gondii infection on host RNA modification profiles and explored how these modifications may influence the host-parasite interaction.

Methodology/principal findings

We analyzed the modification levels of ∼ 80 nt tRNA and 17–50 nt sncRNAs in mouse liver, spleen, and serum using liquid chromatography and tandem mass spectrometry analysis. The results revealed alterations in RNA modification profiles, particularly during acute infection. The liver exhibited more differentially abundant RNA modifications than the spleen. RNA modification levels in serum were mostly downregulated during acute infection compared to control mice. Correlations were detected between different RNA modifications in the liver and spleen during infection and between several RNA modifications and many cytokines. Alterations in RNA modifications affected tRNA stability and protein translation.

Conclusions/significance

These findings provide new insight into the role of RNA modifications in mediating the murine host response to T. gondii infection.

Authors: Hosseininejad Seyyed-Mohsen , Emami Meybodi Mohammad Kazem , Raei Mehdi , Rahimnia Alireza
Published: June 2024

Background

Anterior cruciate ligament (ACL) tear is common in military setting; such an injury increase institutional costs and workforce strain, however, few studies have investigated the mechanism and associated factors of ACL tear specifically in a military setting. The aim of this study was to investigate the prevalence and mechanisms of ACL tears in military personnel at a military referral hospital in Iran.

Material and methods

This cross-sectional study examined 402 military personnel who presented with knee complaints at a single referral Iranian military hospital. The ACL injury prevalence and mechanisms were assessed by physical examination, medical records, and magnetic resonance imaging (MRI) of the knee. Data were collected by an orthopedic resident.

Results

Of the total 402 patients, 285 were diagnosed with ACL tears; the prevalence was 70.9%. The most common mechanism leading to ACL tear was noncontact events. The knee changing direction-knee pivoting (54%) was the most frequent lower limb status, followed by a fall with the knee in valgus position (20.7%). The most commonly associated activity was military training (63.9%) and sports activities (32.6%). The incidence of ACL injuries was higher in soldiers compared with officers during military training, but higher in officers during sports exercises (P = 0.002). Common associated injuries involved the knee meniscus and cartilage.

Conclusion

The findings support those of previous studies, that in military personnel, the most common knee injury is damage to the ACL, most frequently through noncontact events, specifically knee pivoting, during military activities rather than sports and among soldiers. These findings help develop ACL injury prevention programs.

Background

Foster families may represent an alternative model for dependent older adults in many countries where nursing homes are insufficiently developed. This study aimed to assess the prevalence of malnutrition and its determinants in older adults living in foster families in Guadeloupe (French West Indies).

Methods

This cross-sectional study was gathered from the KASAF (Karukera Study of Ageing in Foster families) study (n = 107, 41M/66F, Mdn 81.8 years). Nutritional status was assessed with the Mini Nutritional Assessment Short‐Form (MNA‐SF). Clinical characteristics and scores on geriatric scales (Mini-Mental State Examination (MMSE), Activities of Daily Living (ADL), Short Physical Performance Battery (SPPB), Center for Epidemiologic Studies- Depression (CESD) and Questionnaire Quality of Life Alzheimer’s Disease (QoL-AD)) were extracted. Bivariate analysis and logistic models adjusted for age and gender were performed to test the association of nutritional status with socio-demographic variables and geriatric scales.

Results

Thirty (28.0%) older adults were malnourished (MNA-SF score ≤7). In bivariate analysis, malnutrition was associated with an increased prevalence of cardiovascular diseases (46.7% versus 19.5%, p = 0.004), the presence of hemiplegia (30.0% versus 6.5%, p = 0.003), a poorer cognitive status (MMSE score 4.7 ± 7.1versus 9.7 ± 10.7; p = 0.031), higher risk of depression (CESD score 27.3 ± 23.0 versus 13.5 ± 14.4; p = 0.035) and dependency (ADL score 1.9 ± 1.9 versus 2.3 ± 2.1; p<0.001). Malnutrition was also associated with lower caregivers’rating of QoL (QoL-AD score 21.8 ± 6.4 versus 26.0 ± 5.7; p = 0.001) but not by older adult’s rating (24.1 ± 11.2 versus 28.3 ± 7.7; p = 0.156). Similar associations were observed in logistic models adjusted for age and gender.

Conclusion

Malnutrition was common among foster families for older adults. Special attention towards the prevention and treatment of malnutrition in older adults from cardiovascular diseases, cognitive impairment, dependency and depression is necessary in this model of dependency support.
Supporting kindergarten pupils with developmentally appropriate activities through process art: Ghanaian teachers’ practices
Authors: Yeboah Rita , Godomey Bernard Sprehe
Published: June 2024

This study focused on how kindergarten teachers engage pupils in developmental art activities in Dodowa in the Greater Accra region of Ghana. A case study design was used to collect data through interviews and observations. A purposive sampling technique was used to select eighteen teachers from the nine basic schools in Dodowa. While some of the kindergarten teachers had an understanding of process and product art, others were unfamiliar with these concepts. Product art is typically utilized by teachers to engage pupils in art activities, although this approach may deprive the pupils of the benefits of other developmentally appropriate art activities. Alternatively, process art helps the learners to construct their own knowledge, fosters self-confidence and creativity, and improves visual communication, problem-solving and decision-making skills.

"A-Stoff Anlagen": die Versorgung mit flüssigem Sauerstoff im deutschen Fernraketen Programm 1931-45
Authors: Schmundt-Thomas Georg
Published: June 2024

Die deutsche A4 war die erste einsatzfähige ballistische Fernrakete, als Treibstoff diente ein Gemisch aus Ethanol und flüssigem Sauerstoff. Flüssiger Sauerstoff hatte den Tarnnamen "A-Stoff" und wurde in eigens errichteten Betriebsstätten im Besitz der Wehrmacht hergestellt. Die Sauerstoffwerke waren unter Einsatz von Zwangsarbeitern und KZ-Häftlingen gebaut worden und wurden mit ihnen betrieben. Im Zuge der Planung der Serienfertigung und des militärischen Einsatzes stellte sich spätestens im Sommer 1941 heraus, dass die Herstellung und Versorgung mit flüssigem Sauerstoff das Nadelöhr sein würde, von dem die Gesamtzahl der einsetzbaren Raketen abhängen würde. Die vorliegende Studie basiert auf einer umfassenden Sichtung und Auswertung der relevanten Aktenbestände im Bundesarchiv Militärarchiv in Freiburg und beschreibt die Versorgung mit Flüssigsauerstoff im deutschen Raketenprogramm von den Anfängen in der Weimarer Republik bis zur Kapitulation des Dritten Reichs.

The German A4 rocket was the first operational ballistic missile. It was fueled by a mix of ethanol and liquid oxygen. Liquid oxygen was codenamed "A-Stoff." It was produced in dedicated factories run and operated by the German army. The factories had been built by and were operated using forced labor and concentration camp inmates. As early as summer 1941 it became clear that the supply of liquid oxygen would be the bottleneck, limiting the total number of rockets that could be used. The present study is based on a thorough analysis of existing contemporary files today held at the German Bundesarchiv-Militaerarchiv in Freiburg. It describes how liquid oxygen was provided to the German rocket program from its beginnings during the Weimar republic to the collapse of the Third Reich. The text is in German.

Regimen with Pure Mind
Authors: Tian Ming
Published: June 2024

The basic idea of Regimen with Pure Mind is that people’s spiritual world should be peace and quiet, and his material world should be clean and quiet. The essence of unclean thing is impermanent manifestation of karma, which is not defiled or immaculate. When we recognize the unclean thing in this way, we can achieve spiritual purity. This article uses perception function to analyze the mechanism of addiction, and provides a positive healing method. The key to the regimen is to integrate the body and mind in daily life, feel the physical strain in the correct posture, and give full play to the self-regulation of the human body. The regimen emphasizes that repeating some simple movements can cure many chronic diseases and strains. A person can practice martial arts routines with the way of regimen, then keeps his body at a stable health level; and he can also manage his health through the daily process of regimen.
Therapeutic and developmental benefits of fairy tales in early childhood: A mini-review
Authors: Bakaraki Myrto Patagia , Dourbois Theofanis , Kosiva Alexandra
Published: June 2024

The role of fairy tales in preschool-aged children's emotional and cognitive development is discussed. Separating good from evil makes it easier for children to cope with conflicting emotions. This encourages creative thinking and personality growth as representations of conscious and unconscious motifs in stories guide children through their thoughts. Fairy tales even provide secure, comforting, and supporting feelings though they relate to conflicts or endangerment themes, fostering positive self-image and emotional intelligence in kids. It was found that a happy ending to a fairy tale lessens tension, alleviates anxiety arising from developmental fears, and meets the need for justice among kids. Representation of negative characters in these stories contributes positively to emotional development. In Australia, research has shown that talking about fairy tales helps a child meet emotional needs, especially when told in groups with accompanying acting out. In addition, the article examines how therapeutic fairy tales can decrease fearfulness while dealing with actual life problems throughout this period. Moreover, the paper explores how fairy tales might be used as therapy to address anxiety as well as real-life conflicts during emotional development. Essential for appreciating children’s fantasies that can lead to internal conflicts because of their inability to express themselves in any other manner, it is pertinent for parents and their kids to have storytelling sessions where they can talk about anything. Lastly, fairy tales are sources of inspiration; they teach morals and values; tools necessary for mental growth, cognitive advancement, moral maturity, and creativity, making people think critically and interrogatively.

Authors:   Wojskowa Akademia Techniczna, Warszawa, Ligienza Andrzej , Kastek Mariusz , Sosnowski Tomasz , Firmanty Krzysztof
Published: June 2024

This article focuses on the construction of reference surfaces with the desired spectral characteristics similar to a gray body. Using wooden plywood with a rough surface and coatings of various emissivity values, surfaces with non-selective spectral properties were created. The consistency of laboratory measurement results using a reflectance spectrometer with data obtained from a hyperspectral camera was confirmed. By utilizing multiple reference surfaces with precisely known emissivity characteristics, it will be possible to accurately determine the radiation components of the measured scene’s surroundings. Although the technology of these surfaces still requires improvement, their usefulness in remote sensing measurements is undeniable. Additionally, differences in response to solar radiation between various reference surfaces provide significant information that can be used in remote sensing and material identification. Incorporating the heating dynamics of the studied objects’ surfaces is crucial for accurate measurement modeling.

Increasingly, it is becoming an integral tool when designing, for example, robotic systems. This paper proposes a methodology for the design of robotic systems based on two metamodels: EARL at the implementation platform-independent level and MeROS dedicated to ROS/ROS 2. The procedure is demonstrated by analysing a representative application: a heteregonous multi-robot system with a central coordinator.

An electrocardiogram (ECG) is the first step in diagnosing heart disease. Heart rhythm abnormalities are among the early signs of heart disease, which can contribute to a patient’s heart attack, stroke, or sudden death. The importance of the ECGs has increased with the development of technologies based on machine learning and remote monitoring of vital signs. In particular, early detection of arrhythmias is of great importance when it comes to diagnosing a patient with heart disease. This is made possible through recognizing and classifying pathological patterns in the ECG signal. This paper presents a system for mobile monitoring of ECG signals enriched with the results of the study of the application of machine learning models from the group of Tree-based ML techniques and Neural Networks in the context of heart disease classification. The research was carried out through the use of the publicly available PTB-XL database of the ECG signals. The results were analyzed in the context of classification accuracy for 2, 5 and 15 classes of heart disease. Moreover, a novelty in the work is the proposal of machine learning techniques and architectures neural networks, which, have been selected to be applicable to IoT devices. It has been proven that the proposed solution can run in real time on IoT devices.

The article presents data analysis for predicting energy production in photovoltaic (PV) power plant systems. The purpose of long-term forecasts is to determine the effectiveness of preventive actions and manage the power system effectively. Climate variables affecting the production of electricity in photovoltaic systems were analyzed. Forecasting methods using machine learning techniques such as Multi-Layer Perceptron (MLP) neural networks and Support Vector Machine (SVM) were compared. In addition, metrics were selected to determine the quality of forecasts. Determining the quality of forecasts was based on the actual varying conditions, not on the weather forecast data. The way of data preparation to create forecasting models were presented and the models with the best metrics were selected. For this purpose, the Scikit-learn library was used to create scripts in Python. The best results were obtained for regression models: MLPRegressor, CatBoostRegressor and Support Vector Regression. Actual measurement data from a system of optimally-positioned panels with a power of 3.0 kWp were used. For the MLPRegressor model, the highest coefficient of determination 0.605 was achieved with the smallest root-mean-square error of 1.79 KWh.

For accurate remote temperature measurement with a thermal imaging camera, it is necessary to perform radiometric calibration. This allows the radiative parameters of an object, and therefore its temperature, to be related to the response of the infrared detector observing it. The article presents the basic concepts related to radiometric calibration and various factors influencing its effectiveness. The most common calibration methods were also reviewed, and then two of them were implemented and compared on a specially constructed laboratory station, using proprietary software and equipped with a cooled infrared camera, operating in the MWIR range. The camera was calibrated in the temperature range from 20 °C to 50 ° C. The comparison of methods was carried out on the basis of a series of temperature measurements, analysis of absolute and relative errors, as well as analysis of the dispersion of the measured temperature values.

Authors:   Politechnika Rzeszowska, Świder Zbigniew
Published: June 2024

Selected methods of PID settings for the heading controller in the ship’s autopilot are presented. The consistency of the design is possible due to the fact that the Nomoto model was used for the ship and thanks to the elimination of the time constant of the object by the controller, so that the closed system becomes a 2nd order system. In two cases, it was additionally assumed that the system is to have a double time constant, differing in a given ratio r from the time constant of the object. It has been shown that the heading controller designed in this way provides critical aperiodic waveforms at a step change in the setpoint value and suppresses environmental disturbances better than standardly tuned controllers.

In the following article, the results of a study on the impact of the suspension system used in Unmanned Ground Vehicles (UGVs) on the kinematic excitation of cameras in teleoperation systems are presented. As indicated by preliminary reconnaissance studies, these excitations significantly affect the operator’s ability to perceive the environment and recognize images while driving. Currently, there is a lack of publications and guidelines in the literature regarding the design of UGV suspensions and their evaluation in terms of improving operator perception in teleoperation systems. The studies were conducted in a simulated environment using multibody systems, where various suspension structure variants were developed. The tests were carried out on the ISO 5008 rough test track. The evaluation of the tested suspension structures was carried out using a proprietary method, enabling parametric analysis and the selection of favorable solutions for improving image recognition by the UGV operator. Future research can focus on adjustment of the UGV suspension characteristics which could have significant influence on situational awareness and the operator’s ability to act effectively, especially during dynamic missions.

Arm-Z is a conceptual hyperredundant robotic manipulator composed on linearly joined number of identical modules. Each of them has one-degree-of-freedom (1-DOF) – the relative twist. Since modules are congruent, Arm-Z presents potential economical advantages and enhanced robustness. The modules can be mass produced and easily replaceable. The control of Arm-Z, however, is difficult and not intuitive. Therefore it most often requires the use of computational intelligence techniques. This article presents selected concepts for kinetic street furniture based on Arm-Z: a helical column of adjustable height, a sun tracking shade or solar energy harvesting device, bio-mimicing sculpture, sprinkler or fountain. All these ideas are based on low-tech approach. For this purpose, the initial unit in the chain is fixed to the solid foundation. For simplicity, the drive is applied directly to the first unit and transferred by the means of internal gears to the following modules. All of them are equipped with a set of cylindrical and bevel gears with straight teeth with involute profile (for connecting the modules).

Purpose: This study aimed to establish baseline morphological and functional data for normal mouse kidneys via a clinical 33 MHz ultra-high-frequency (UHF) transducer, compare the data with the findings from fibrotic mice, and assess correlations between ultrasonography (US) parameters and fibrosis-related markers.Methods: This retrospective study aggregated data from three separate experiments (obstructive nephropathy, diabetic nephropathy, and acute-to-chronic kidney injury models). Morphological parameters (kidney size, parenchymal thickness [PT]) and functional (shear-wave speed [SWS], stiffness, resistive index [RI], and microvascular imaging-derived vascular index [VI]) were assessed and compared between normal and fibrotic mouse kidneys. Semi-quantitative histopathologic scores were calculated and molecular markers (epithelial cadherin), Collagen 1A1 [Col1A1], transforming growth factor-β, and α-smooth muscle actin [α-SMA]) were evaluated using western blots. Correlations with US parameters were explored.Results: Clinical UHF US successfully imaged the kidneys of the experimental mice. A three-layer configuration was prevalent in the normal mouse kidney parenchyma (34/35) but was blurred in most fibrotic mouse kidneys (33/40). US parameters, including size (11.14 vs. 10.70 mm), PT (2.07 vs. 1.24 mm), RI (0.64 vs. 0.77), VI (22.55% vs. 11.47%, only for non-obstructive kidneys), SWS (1.67 vs. 2.06 m/s), and stiffness (8.23 vs. 12.92 kPa), showed significant differences between normal and fibrotic kidneys (P<0.001). These parameters also demonstrated strong discriminative ability in receiver operating characteristic curve analysis (area under the curve, 0.76 to 0.95; P<0.001). PT, VI, and RI were significantly correlated with histological fibrosis markers (ρ=-0.64 to -0.68 for PT and VI, ρ=0.71-0.76 for RI, P<0.001). VI exhibited strong negative correlations with Col1A1 (ρ=-0.76, P=0.006) and α-SMA (ρ=-0.75, P=0.009).Conclusion: Clinical UHF US effectively distinguished normal and fibrotic mouse kidneys, indicating the potential of US parameters, notably VI, as noninvasive markers for tracking fibrosis initiation and progression in mouse kidney fibrosis models.

Published: June 2024

Fatigue is a persistent and debilitating feeling of tiredness that limits the ability to perform daily activities and is a common and difficult-to-treat condition in patients with rheumatic diseases (RD). Fatigue is a major challenge for the physician. However, methods to treat it have not yet been developed, as fatigue is usually considered an insignificant background condition. This article provides an overview of the 2023 EULAR recommendations, which outline the guiding principles and strategy for the management of fatigue in patients with RD. The EULAR recommendations are based on an understanding of fatigue as a complex condition that requires an individualized approach in choosing the correction methods. It is important that the assessment of fatigue becomes part of the routine practice of rheumatologists and other physicians. Patient education recommendations emphasize the importance of an individualized approach tailored to the needs of the individual, including optimizing physical activity and psychoeducational interventions.
