The conversion of agricultural land at a high enough rate may threaten the food security of the population. The agricultural land most vulnerable to conversion is the rice field. The aim of this study was to determine the changes in paddy fields from 2013 to 2020, the distribution of the transformation of paddy fields to other lands, and the factors that influence the conversion of paddy fields. This research was carried out by digitizing the on-screen image method in 2013 and 2020. The classification of land use results from digitization was tested for accuracy by determining the sample points in the GIS (Geographic Information System) application and then compared to the results of the field survey. In addition, an analysis of the changes in paddy fields was carried out by overlaying land use maps in 2013 and 2020. Observations and interviews with people whose land was changing were conducted on the factors affecting the change in paddy fields. Changes in land use over a period of 7 years (2013-2020), namely rice fields, decreased by 149 ha (7.36 percent ). Meanwhile, there has been an increase in the area in other land uses. The function of the paddy fields in the urban area of Pangkajene, Sidrap Regency, has become 18.69 hectares of land built, 59.42 hectares of mixed gardens, 23.13 hectares of open/empty land and 49.11 hectares of land. The factor that affects the conversion of paddy fields in the urban area of Pangkajene is the strategic location of the land, which causes the community to convert its land into a place of trade and services. The increase in the number of people requiring large land areas has led to the construction of many residential complexes in rice fields and the high selling price of rice fields, which encourages farmers to sell their land.

Furin knockdown inhibited EndMT and abnormal proliferation and migration of endothelial cells
Authors: Zeng Rui , Wang Yimin , Chen Jun , Liu Qiang
Published: May 2024

BACKGROUND: In the pathogenesis of atherosclerotic cardiovascular disorders, vascular endothelium is crucial. A critical step in the development of atherosclerosis is endothelial dysfunction. Furin may play a factor in vascular remodeling, inflammatory cell infiltration, regulation of plaque stability, and atherosclerosis by affecting the adhesion and migration of endothelial cells. It is yet unknown, though, how furin contributes to endothelial dysfunction. METHODS: We stimulated endothelial cells with oxidized modified lipoprotein (ox-LDL). Endothelial-to-mesenchymal transition (EndMT) was found using immunofluorescence (IF) and western blot (WB). Furin expression level and Hippo/YAP signal activation were found using reverse transcription-quantitative PCR (RT-qPCR) and WB, respectively. To achieve the goal of furin knockdown, we transfected siRNA using the RNA transmate reagent. Following furin knockdown, cell proliferation, and migration were assessed by the CCK-8, scratch assay, and transwell gold assay, respectively. WB and IF both picked up on EndMT. WB and RT-qPCR, respectively, were used to find furin’s expression level. We chose the important micrornas that can regulate furin and we then confirmed them using RT-qPCR. RESULTS: EndMT was created by ox-LDL, evidenced by the up-regulation of mesenchymal cell markers and the down-regulation of endothelial cell markers. Furin expression levels in both protein and mRNA were increased, and the Hippo/YAP signaling pathway was turned on. Furin knockdown dramatically reduced the aberrant migration and proliferation of endothelial cells by ox-LDL stimulation. Furin knockdown can also suppress ox-LDL-induced EndMT, up-regulate indicators of endothelial cells, and down-regulate markers of mesenchymal cells. After ox-LDL stimulation and siRNA transfection, furin’s expression level was up-regulated and down-regulated. CONCLUSION: Our study demonstrated that furin knockdown could affect ox-LDL-induced abnormal endothelial cell proliferation, migration, and EndMT. This implies that furin plays an important role in endothelial dysfunction.

Resonant coil matrix shielding for dynamic WPT systems
Authors: Zhu Junda , Barmada Sami , Ceraolo Massimo , Fontana Nunzia , Musolino Antonino
Published: May 2024

In this article, a magnetic shield for automotive Wireless Power Transfer (WPT) systems is proposed. Its innovative feature consists in the positioning of the shield, that is part of the Ground Assembly (GA) of the WPT system. Passive coils, assembled in an array-like structure to build the shields properly located near the transmitting coils are investigated. Currently, there are a variety of shielding methods, each of them with its peculiar feature. The proposed method is simple and does not increase the transmitting and the receiving coil sizes, a constraint that is often critical from a practical and an economical point of view. The main characteristic of the proposed shielding method is the location of the shielding coils on the same level as the GA. The results here presented are validated by Finite Element (FE) based simulations and are referred to an experimental prototype of wireless charging systems for electric vehicles operating at 85 kHz with a transmitted nominal power of 3.3 kW. The results show that the proposed shield reduces the leakage magnetic flux density in the system up to 37% with a marginal impact on the transmission efficiency, complying the SAE J2954 international standard.

BACKGROUND: The road to employment can be uncertain for millions of adults with intellectual disability and their families. It is important to understand how they navigate this journey and the challenges they experience. OBJECTIVE: We examined the pathways taken by four families in their pursuit of integrated employment, as well as the complexities they encountered along the way. METHOD: In this longitudinal, multiple case study, we followed families across one year. They (and their mentors) completed questionnaires at the beginning of the project, we checked in with them monthly, and we interviewed them at the conclusion of the project. RESULTS: Five primary findings emerged from their experiences: pursuing employment is a family affair, it is an extended journey, each family’s journey is different, mentorship matters, and multifaceted support is needed. CONCLUSION: Families need ongoing support and guidance to navigate their journey toward competitive employment. We offer recommendations for research and practice aimed at supporting families in this important pursuit.
Modeling of the magnetorefractive effect in Co-Al2O3 nanocomposites in the framework of the Bruggeman approximation
Authors: Mukhutdinova M. A. , Yurasov A. N.
Published: May 2024

Objectives. To investigate the magnetorefractive effect (MRE) in nanocomposites, which consists in changing the reflection, transmittance and light absorption coefficients of samples with large magnetoresistance (MR) upon their magnetization. Materials offering high magneto-optical activity and significant MR include magnetic nanocomposites. These materials are based on a polymer matrix, which includes inorganic magnetic particles, fibers or layered particles, whose nanometer sizes range from 1 to 100 nm in at least one dimension. The main purpose of creating such nanocomposites is to combine the special properties of several components in one material. The presence in such materials of gigantic, colossal and tunneling MR, as well as the giant anomalous Hall effect, is of practical interest. Uses range from magnetic recording, light modulation, and receivers for thermal radiation, while the MRE itself is a promising method for the non-destructive testing of any nanostructures, e.g., measuring MR.

Methods. The use of effective medium theory to describe the optics and magneto-optics of dispersed media provides a means to determine the complex permittivity of a medium through the permittivity of its constituent components or vice versa. The present work considers the example of a Co-Al2O3 nanocomposite with a concentration of ferromagnetic metal Co 0.4 near the percolation threshold. This particular case was considered for study, since all the properties of nanocomposites change dramatically near the percolation threshold.

Results. Using the Bruggeman effective medium approximation (EMA) to describe the optical and magneto-optical properties of nanocomposites on the example of Co-Al2O3, the characteristics of MRE are obtained, namely, the change in MRE for reflection and transmission of light at normal incidence and at the angle of incidence near the Brewster angle (below the percolation threshold) or the main angle of incidence for metals (above the percolation threshold), which enhances MRE. The advantage of the EMA is the ability to study magneto-optical spectra in the range of average volume concentrations of the metal component.

Conclusions. The obtained values correspond well to the known experimental data. Moreover, the described approach can be used to study any nanostructures.

Methods. The research utilized methods of experimentation, induction, testing, and statistical analysis.

Results. The main features, architecture and modes of operation of the PgBouncer service are considered. Load testing was carried out on a virtual machine deployed on the basis of an open cloud platform with different configurations of computing resources (CPU, RAM) and according to several scenarios with different configurations and different numbers of balancer connections to the database, during which the following main indicators were investigated: distribution of processor usage, utilization of RAM, disk space, and CPU. The interpretation of the data obtained and the analysis of the results obtained by highlighting critical parameters are performed. On the basis of results analysis, conclusions and recommendations are formulated on the use of a connection balancer in real high-load installations for optimizing the resources utilized by the server on which the database management system (DBMS) is located. A conclusion is presented on the usefulness of using the PgBouncer query balancer along with proposed configuration options for subsequent use in real installations.

Conclusions. The degree of influence of the use of the PgBouncer connection balancer on the performance of the system as a whole deployed in a virtualized environment is investigated. The results of the work showed that the use of PgBouncer allows significantly optimization of the computing resources of a computing node for a DBMS server, namely, load on the CPU decreased by 15%, RAM—by 25–50%, disk subsystem—by 20%, depending on the test scenarios, the number of connections to the database, and the configuration of the connection balancer.

Apparent Hysteresis in Archie’s Law: Implications of Changing Pore Fluid Conductivity for Electrical Resistivity Monitoring of Infiltration
Authors: Pope Gina Ginevra , Nyquist Jonathan E.
Published: May 2024

The electrical resistivity of the vadose zone is highly dependent on soil moisture content (VWC), making ERT a potential tool for non-intrusive infiltration monitoring. There’s a long history of using Archie’s law to convert resistivity values to VWC, often under the assumption that the pore-fluid conductivity is constant. Analysis of two years of soil conductivity and VWC data from sensors buried in a bioswale in Philadelphia, Pennsylvania showed that the characteristic curve of VWC versus resistivity exhibited hysteresis. The same value of resistivity was associated with different VWC during imbibition and drying. Accurate VWC could be estimated using Archie’s law only after incorporating changes in pore-fluid conductivity. Additionally, pore-fluid conductivity varied seasonally, with the highest values recorded during winter from road salt runoff. Archie exponents differed for sensors within 25 cm of each other despite both the uniform nature of the bioswale soil and fits to Archie’s Law for individual sensors, indicating considerable heterogeneity. This pattern was confirmed at two additional sites. Assuming the conductivity of the pore-fluid remains constant during infiltration not only produces erroneous soil moisture estimates, it can even reverse the apparent soil moisture trend. We conclude that to use ERT to monitor infiltration it is essential to independently record changes in pore-fluid conductivity, and that multiple sensors are required because changes in pore-fluid conductivity and Archie parameters can vary on a sub-meter scale for even apparently homogeneous sites. Additionally, long-term changes in Archie parameters, notably m, are possible, and may indicate long-term changes in soil fabric.

The Concept of Constitutional Identity as a Substantive Expression of the Principle of Subsidiarity
Authors: Orbán Endre
Published: May 2024

The introduction of the subsidiarity principle by the Maastricht Treaty was intended to strike a balance between the Member States and the supranational level in terms of non-exclusive competences. However, the principle of subsidiarity in the current EU structure is Janus-faced: although it was theoretically included in the founding treaty to protect the lower levels, its modus operandi is actually aimed at demonstrating the supranational level’s capacity to act. Perhaps this is why the enshrinement of the subsidiarity principle in the Treaty has not lived up to expectations, and the relevant Treaty provisions have largely remained dead letters. At the same time, the need represented by the principle of subsidiarity, namely the protection of the autonomy of the Member States, remained present in European integration, which finally emerged in the concept of constitutional identity, linked to the redefined identity clause after the Lisbon Treaty. In this sense, the identity clause in Article 4(2) TEU has become the legal device or standard that is able to transfer the constitutional needs of the Member States to the level of EU law and provide the possibility for their recognition at EU level. For this to work, a cooperative approach by national constitutional courts seems essential.

Routing and clustering based energy optimization techniques in 5G networks for improving the performance and lifetime
Authors: Rubeena Fathima , Patidar Raghavendra
Published: May 2024

The 5G networks are the integral components of Wireless sensor networks also known as WSNs, providing critical data collection and monitoring capabilities. However, the limited energy resources of sensor nodes pose a significant challenge in maintaining the network’s efficiency and longevity. To address this challenge, routing and clustering techniques have been extensively studied and employed to optimize energy consumption in WSNs. In the context of 5G networks, these techniques are tailored to improve the lifetime and overall performance of the network. Routing and clustering techniques in WSNs can be adapted and optimized for 5G networks to enhance energy efficiency and extend the network lifetime. The selection of specific techniques depends on the network characteristics, application requirements, and available resources. Ongoing research and development in this field aim to further enhance energy optimization techniques for the evolving needs of 5G networks. WSNs consist of numerous devices called sensor nodes which communicate with each other. Their main function is to sense the factors of the environment in which they have been deployed. The wireless communication techniques are utilized appropriately by the sensor nodes to communicate with each other. These techniques are governed by routing protocols based on the clustering process. Clustering is implemented using a new technique that is based on the social behavior of the network. Based on the above proposal, clusters are formed and these clusters are divided into two groups analogous to male and female herds. In the male group, the cluster head changes after every round of communication whereas in the female group, cluster heads continue until their energy is not drained. This results in improving the lifetime of networks resulting in a long time of communication as the nodes remain alive for a longer amount of time and clusters also continue for a longer period of time. In comparison with the existing techniques, this method based on Routing and Clustering based optimization gives better results in terms of lifetime, energy consumption, and the number of alive nodes. Also, energy consumption reduces substantially resulting in an optimal network.
The integration of technological devices for the development of oral interaction competence in secondary schools
Authors: Boufnichel Hafida , Louiz Driss
Published: May 2024

History tells us about a mutation in the conception of learning: the linear or transmissive conception is succeeded by the interactional conception, which envisages learning as a developmental process based on co-action and collaboration. This conceptual shift has had a major impact on the didactics of foreign languages (FL/L2), where we are witnessing a change in both the object and the teaching-learning method. Indeed, if in the era of behaviorism and structural linguistics, the objective was to develop linguistic competence in the learner through structural exercises, and that during the 1970s–1980s, with the emergence of the cognitivist movement, sociolinguistics, speech act theory and pragmatics, the objective of learning L2s became the development of communication skills in the target language, a little later , and from the beginning of the 90s, having experienced the flagship of the socio-constructivist current and the interactionist theory of development, the individualist concept of learning is widely criticized and it is the interaction skill that we seek to develop among the learner through collaborative activities in person and remotely, the latter becoming possible thanks to the development of information and communication technologies (ICT). The objective of school training is to prepare a citizen capable of integrating into a professional world which is based on interaction and collaboration in the realization of projects and in which the use of technologies continues to expand. increase. The idea that challenged us in our research is to know to what extent the new learning paradigm is interpreted by institutional didactics. The analysis of the school textbook Le Français au Collège, designed for the second year of the secondary school cycle, revealed to us a gap between the theoretical anchoring and what is proposed as an oral methodological approach.

Post-to-Facebook data have been eliminated from text and image analysis investigations on Social Media (SM) participation, which have tested techniques for predicting activity. SM has fundamentally revolutionised the marketing division by presenting a direct link to users’ inboxes. This research investigates Natural Language Processing (NLP) and Deep Convolutional Neural Networks (DeepCNN) to determine whether these technologies can improve SMA. Advertisers can support their SMA approaches by employing earlier methods to recognise consumer demands, behaviours, and preferences. A novel technique that integrates Deep Learning and Natural Language Processing in order to improve SM awareness has the possibility of helping revolutionise on-line advertising techniques, opening the for additional studies, and setting foundations for a Decision-Making System (DMS) which includes advertising data analytics and Artificial Intelligence (AI). A distinctive framework that forecasts how users behave using like count, post count, and sentiment was built utilising 500k posts on Facebook as the basis for the research investigation’s approach. Image and text data performed better than unpredictability methods, demonstrating that data fusion is essential when predicting user behaviour.

Designing the utility planning concept for the Ampera Medan road corridor, it starts with identifying the condition of the drainage system, traffic signs, road markings, public road lighting, and road user safety devices. Furthermore, a study of changes to road utility requirements is carried out by road management guidelines and road environmental conditions in the form of improving kindness on the road surface, installing signs and warning devices, installing flashing lights, removing roadblocks, and installing noise tape based on certain distances. This research aims to produce a design concept for road utility planning that is environmentally friendly and sustainable (sustainable road) under the guidelines of the Ministry of PUPR while still paying attention to basic human needs and economic growth. Research and knowledge related to the concept of environmentally friendly road utility planning on the Jalan Ampera Medan corridor is a contribution to scientific work that can provide benefits to the Muhammadiyah University of North Sumatra and the Medan City Government as material for consideration and decisions in the construction of environmentally friendly roads (green roads) in the city Medan.
Erken Sönen Güneş Işığı: Şair Petya Dubarova‘nın Hüzünlü Hikayesi
Authors: Atasoy İsmail Orkun , Atasoy Emin
Published: May 2024

Öz: Bulgar edebiyatının en yetenekli, en genç ve en ünlü temsilcilerinden biri olan Petya Dubarova Türkiye’de pek tanınmayan bir şairdır. Bu nedenle bu araştırmanın öncelikli amacı Bulgar yazarı Türk okuyucularına ve bilim dünyasına tanıtmaktır. Haksızlıklar ve adaletsizlik karşısında dik durduğu için Petya dünyayı çok erken terk etmiş. Muhteşem yeteneğini sonuna kadar ortaya çıkarmadan ve belki de en güzel şiirlerini kaleme almadan daha 17 yaşında intihar ederek yaşama veda etmiştir. Bu araştırmada Dubarova’nın renkli ve hüzünlü hayat hikâyesi büyüteç altına alınmış, ayrıca hem “Öğrenci Petya”nın hem de “Şair Petya”nın portresi resmedilmeye çalışılmıştır. Araştırmanın özeğinde Petya’nın öz yaşamı, romantik aşkları, öğrencilik yılları, yaşadığı kişisel sorunlar ve yazarlık yeteneği yer almaktadır. Petya Dubarova Bulgaristan’ın unutulamayan, henüz çocuk yaşta olağanüstü yeteneğiyle dikkat çeken şairlerinden biridir. Onun şiirsel kalıtı genellikle çocuksu arılığı, ergenlik yürekliliğini, felsefi sorgulamaları ve müthiş yaratıcılığı yansıtmaktadır. Dubarova geride yüzlerce yanıtsız soru bırakarak, çok genç yaşta yaşamına son vererek bizlerden ayrılmıştır. Kısa yaşamında bizi şaşırtmayı başarmış, ne var ki muazzam yeteneğinin yalnızca küçük bir ipucu vermiştir bizlere. Yaşamında da ölümünden sonra da bu genç yetenek tam olarak kavranamamış ve çevresindeki gizemli bulut da bir türlü çözülememiştir. Türk okuyucuları çocuk yaştaki bu yazarı pek bilmedikleri için hüzünlü yaşam serüvenini ve ozan olarak başarılarını bir makalede irdelemenin yararlı olacağı düşünülmüştür. Bu araştırmanın, Bulgar edebiyatı alanında ülkemizde önemli bir yayın boşluğunu doldurması umut edilmektedir.

Prof. Dr. Hüseyin Atay’ın, “Ben: Akıl ve Kur’an Işığında 1400 Yıllık Süreçte İslam’ın Evreni” adlı son kitabını temel alarak onun din alanındaki görüşlerinden bazılarını gündeme taşımanın yararlı olacağı kanısındayım. Hocamın 3 Nisan 2019 da imzalı olarak bana verdiği kitabının okumasını 12 Mayıs 2019’da kendime özgü yöntemle bitirdim. Prof. Dr. Hasan Onat Hocadan da acilen söz konusu kitabı okumasını istedim. İki ay içinde Onat Hoca da okudu. Biz kitabı hocayla tartışmak için uygun zaman ararken, Atay Hoca hastalandı. 26 Eylül 2020’de Hasan Onat Hoca vefat etti. 31 Ağustos 2023’de de Hüseyin Atay Hoca da vefat etti. Her iki hocamıza Allah rahmet eylesin. Mekanları cennet olsun. Bu değerlendirmelerimi her iki hocamızla yapamamış olmanın üzüntüsü içindeyim. Ben de Atay Hoca’nın yazdığı son kitabında açıkladığı ve önemli bulduğum bazı görüşleri hakkındaki değerlendirmelerimi okuyucularımla da paylaşmak istiyorum.

The global resurgence of bed bug infestations, exacerbated by increasing international travel, trade, and insecticide resistance, has significantly impacted Korea. This study identified the bed bug species and performed pyrethroid resistance genotyping of recently resurgent bed bugs in Korea. Thirty-one regional bed bug samples were collected from 5 administrative regions: Gyeonggi-do (n=14), Seoul (n=13), Busan (n=2), Jeonllanam-do (n=1), and Chungcheongbuk-do (n=1). The samples underwent morphological and molecular identification. Twenty-four regional samples (77.4%) were identified as the tropical bed bug, Cimex hemipterus, and the remaining 7 regional samples (22.6%) were identified as the common bed bug, Cimex lectularius. The C. hemipterus regional samples carried at least three mutations associated with knockdown resistance (kdr), including 2 super-kdr mutations. The 7 C. lectularius regional samples possessed at least one of the 3 kdr-related mutations associated with pyrethroid resistance. This study confirms that the prevalent bed bug species recently in Korea is C. hemipterus, replacing the previously endemic C. lectularius. Additionally, the rise in bed bug populations with pyrethroid resistance underscores the necessity of introducing alternative insecticides.
‘It was not Sinai’: Wayfaring with Nijinsky in and around St. Moritz. Some Reflections on Practising Dance History in the Field
Authors: Klimczyk Wojciech
Published: May 2024

Among the most enigmatic passages in the so-called ‘diary’ of Vaslav Nijinsky are the four descriptions of the walks Nijinsky presumably took around St. Moritz where he moved in 1917. This article concerns research on these walks conducted by the author in St. Moritz, by means of wayfaring as conceptualized by Tim Ingold. It presents the current state of the sites mentioned by the dancer and hypothesizes about his routes and the dramatic effects of walks through the Upper Engandine landscape. It also ponders the impossibility of accessing the ‘original’ sites, and hence the walks as they happened, as well as the advantages of this impossibility for a more open dance history.
