Published: June 2022

Heparin has shown benefits in severe acute pancreatitis (SAP) therapy, but the underlying mechanisms were unknown. Extracellular high-mobility group protein-1 (HMGB-1) has been regarded as a central mediator contributing to inflammation exacerbation and disease aggravation. We hypothesized heparin attenuated the disease by targeting HMGB-1-related pathways. In the present study, the possible therapeutic roles of heparin and its non-anticoagulant derivatives, 6-O-desulfulted heparin and N-acylated-heparin, were determined on mouse models induced by “Two-Hit” of L-arginine. The compounds exhibited potent efficiency by substantially decreasing the pancreatic necrosis, macrophage infiltration, and serum inflammatory cytokine (IL-6 and TNF-α) concentration. Moreover, they greatly reduced the rapidly increasing extracellular HMGB-1 levels in the L-arginine injured pancreases. As a result, multiple organ failure and mortality of the mice were inhibited. Furthermore, the drugs were incubated with the RAW264.7 cells activated with damaged pancreatic tissue of SAP mice in vitro. They were found to inhibit HMGB-1 transfer from the nucleus to the plasma, a critical step during HMGB-1 active secretion from macrophages. The results were carefully re-examined with a caerulein and LPS induced mouse model, and similar results were found. The paper demonstrated heparin alleviated SAP independent of the anti-coagulant functions. Therefore, non-anticoagulant heparin derivatives might become promising approaches to treat patients suffering from SAP.

Published: June 2022

The feasibility of joining material extrusion (MEX) 3D-printed acrylonitrile butadiene styrene (ABS) plates with the friction stir welding (FSW) process was investigated herein as a promising topic of hybrid additive manufacturing (HAM). The influence of three process parameters on the mechanical strength of the joints was thoroughly examined and analyzed with a full factorial experimental design and statistical modeling. Hereto, the welding tool pin geometry, travel speed, and rotational speed were investigated. The joint’s efficiency and quality are evaluated through tensile tests and morphological characterization. More specifically, specimens’ areas of particular interest were investigated with stereoscopic, optical, and scanning electron microscopy. Throughout the FSW experimental course, the welding temperature was monitored to evaluate the state of the ABS material during the process. The majority of the welded specimens exhibited increased mechanical strength compared with the respective ones of non-welded 3D printed specimens of the same geometry. Statistical modeling proved that all processing parameters were significant. The feasibility of the FSW process in 3D printed ABS workpieces was confirmed, making the FSW a cost-effective process for joining 3D printing parts, further expanding the industrial merit of the approach.
Flared Gas Can Reduce Some Risks in Crypto Mining as Well as Oil and Gas Operations
Authors: Vazquez Jennifer , Crumbley Donald Larry
Published: June 2022

There are numerous risks associated with mining and owning cryptocurrencies, and exploring and producing oil and natural gas are highly risky, costly, and controversial. A marriage of digital mining and exploring and producing oil and natural gas has reduced the major risks and costs for both the crypto miner and the petroleum industry. On the one hand, crypto mining requires an enormous amount of electricity, which is not environmentally friendly. On the other hand, when drilling for petroleum resources, natural gas is often discovered, but due to a lack of resources or pipeline availability, a massive amount of natural gas is vented into the atmosphere or burned (called flaring). Today, however, this normally wasted gas (called stranded natural gas) is being used to create cheap electricity for mining server containers stationed near drilling rigs, which are used to create cryptocurrencies. This results in reduced CO2 emissions, lower costs for drillers, and greater royalties going to landowners.

Published: June 2022

For skywave over-the-horizon radar, beamforming techniques are often used to suppress airspace radio frequency interference because the high-frequency band is shared by many devices. To address the problems that the traditional beamforming method is not capable of recognizing the electromagnetic environment and that its performance is greatly affected by the accuracy of signal feature estimation, a cognitive beamforming method using range-Doppler (RD) map features for skywave radar is proposed. First, the RD map is weighted by a local attention model, and then, texture features are extracted as the inputs to a support vector machine. Finally, the support vector machine is used to predict the optimal diagonal loading factor. Simulation results show that the output signal-to-interference-plus-noise ratio is improved compared with previous methods. The proposed method is suitable for many kinds of common unsatisfactory scenarios, making it beneficial for engineering implementation.
Variability of Marine Particle Size Distributions and the Correlations with Inherent Optical Properties in the Coastal Waters of the Northern South China Sea

Published: June 2022

Particle size distribution (PSD), which is an important characteristic of marine suspended particles, plays a role in how light transfers in the ocean and impacts the ocean’s inherent optical properties (IOPs). However, PSD properties and the correlations with IOPs are rarely reported in coastal waters with complex optical properties. This study investigated the PSD variabilities both for the surface water and the water in vertical planes, and the correlations between PSD and the backscattering coefficient (bbp), scattering coefficient (bp), and attenuation coefficient (cp), based on in situ PSD observations (within a size range of 2.05–297 μm) and IOPs in the coastal northern South China Sea. The results show a large variety of PSDs, with a range of 41.06–263.02 μm for the median particle diameter (Dv50) and a range of 2.61–3.74 for the PSD slope. In addition, the predominance of small particles is most likely to appear in the nearshore shallow water and estuaries with a large amount of sediment discharge, and vice versa. For the variabilities of IOPs, the particle concentration in a cross-sectional area (AC) is the first driving factor of the variations of bbp, bp, and cp, and the product of the mean particle diameter (DA) and the apparent density (ρa) can explain most variations of the mass-specific bbp (bbp/SPM), bp (bp/SPM), and cp (cp/SPM). In this study, we found that particle size is strongly correlated with volume-specific bbp (bbp/VC), bp (bp/VC), and cp (cp/VC), and the 10th percentile diameter of the accumulated volume concentration (Dv10) can better explain the variations of bbp/VC. These findings suggest a potential PSD retrieval method utilizing the bbp or bp, which may be determined by remote sensing observations.

Published: June 2022

As a kind of soil-borne epidemic disease, bacterial wilt (BW) is one of the most serious diseases in tomatoes in southern China, which may significantly reduce food quality and the total amount of yield. Hyperspectral remote sensing can detect crop diseases in the early stages and offers potential for BW detection in tomatoes. Tomatoes in southern China are commonly cultivated in greenhouses or bird nets, limiting the application of remote sensing based on natural sunlight. To resolve these issues, we collected the spectrum of tomatoes firstly using the HS-VN1000B Portable Intelligent Spectrometer, which is equipped with a simulated solar light source. We then proposed a tomato BW detection model based on some optimal spectral features. Specifically, these optimal features, including vegetation indexes and principal components (PCs), were extracted by the sequential forward selection (SFS), the simulated annealing (SA), and the genetic algorithm (GA) and were finally fed into the support vector machine (SVM) classifier to detect diseased tomatoes. The results showed that the infected and healthy tomatoes exhibit different spectral characteristics for both leave and stem spectra, especially for near-infrared bands. In addition, the BW detecting model built by the combination of GA and SVM (GA-SVM) achieved the best performance with overall accuracies (OA) of 90.7% for leaves and 92.6% for stems. Compared with the results based on leaves, spectral features of stems provided better accuracy, indicating that the symptom of early infection of BW is more significant in tomato stems than in leaves. Further, the reliability of the GA-SVM tomato stem model was verified in our 2022 experiment with an OA of 88.6% and an F1 score of 0.80. Our study provides an effective means to detect BW disease of tomatoes in the early stages, which could help farmers manage their tomato production and effectively prevent pesticide abuse.
Spatiotemporal Filtering for Continuous GPS Coordinate Time Series in Mainland China by Using Independent Component Analysis
Authors: Zhou Wei , Ding Kaihua , Liu Peng , Lan Guanghong , Ming Zutao
Published: June 2022

Continuous Global Positioning Systems (GPS) coordinate time series with a high spatiotemporal resolution, and provide a great opportunity to study their noise models and common mode errors (CMEs), thus making it possible to detect and analyse spatiotemporal characteristics of tectonic and non-tectonic signals in time series, and further to estimate a reliable and accurate velocity field of crustal movement in a region by removing CMEs and using the optimal noise model. In this paper, we used GPS coordinate time series from the Crustal Movement Observation Network of China (CMONOC) with an approximate decadal period from 2010 to 2020, to construct optimal noise models by fitting them with several noise combinations according to the Akaike information criterion (AIC). We further adopted independent component analysis (ICA) to extract CMEs and analysed their spatiotemporal characteristics, and then evaluated their effects on noise models and velocity uncertainties, and finally estimated a decennial velocity field of crustal movement with a higher signal-to-noise ratio (SNR) by applying the CME filtering and considering the optimal noise model in Mainland China. Our results show that optimal noise models are dominated by white noise (WN) plus flicker noise (FN) for both east and north components, and WN plus power law noise (PN) with spectral index close to −1 for up component, respectively. ICA filtering can remove the highly spatially correlated CMEs and decrease the mean RMSEs of the residual time series by about 40–60%, providing a more accurate velocity field with a higher SNR in Mainland China, accordingly.
Encoder-Decoder Structure with Multiscale Receptive Field Block for Unsupervised Depth Estimation from Monocular Video
Authors: Chen Songnan , Han Junyu , Tang Mengxia , Dong Ruifang , Kan Jiangming
Published: June 2022

Monocular depth estimation is a fundamental yet challenging task in computer vision as depth information will be lost when 3D scenes are mapped to 2D images. Although deep learning-based methods have led to considerable improvements for this task in a single image, most existing approaches still fail to overcome this limitation. Supervised learning methods model depth estimation as a regression problem and, as a result, require large amounts of ground truth depth data for training in actual scenarios. Unsupervised learning methods treat depth estimation as the synthesis of a new disparity map, which means that rectified stereo image pairs need to be used as the training dataset. Aiming to solve such problem, we present an encoder-decoder based framework, which infers depth maps from monocular video snippets in an unsupervised manner. First, we design an unsupervised learning scheme for the monocular depth estimation task based on the basic principles of structure from motion (SfM) and it only uses adjacent video clips rather than paired training data as supervision. Second, our method predicts two confidence masks to improve the robustness of the depth estimation model to avoid the occlusion problem. Finally, we leverage the largest scale and minimum depth loss instead of the multiscale and average loss to improve the accuracy of depth estimation. The experimental results on the benchmark KITTI dataset for depth estimation show that our method outperforms competing unsupervised methods.
Diverse-Region Hyperspectral Image Classification via Superpixelwise Graph Convolution Technique
Authors: Huang Yan , Zhou Xiao , Xi Bobo , Li Jiaojiao , Kang Jian , Tang Shiyang , Chen Zhanye , Hong Wei
Published: June 2022

In this paper, a diverse-region hyperspectral image classification (DRHy) method is proposed by considering both irregularly local pixels and globally contextual connections between pixels. Specifically, the proposed method is operated on non-Euclidean graphs, which are constructed by superpixel segmentation methods for diverse regions to cluster irregularly local-region pixels. In addition, the dimensionality reduction method is employed to alleviate the curse of dimensionality problem with a lower computational burden, generating more representative data with the input graph features. In this context, it then constructs a superpixelwise Chebyshev polynomial graph convolution network (ChebyNet) to aggregate global-region superpixels. Benefiting from different superpixel numbers of segmentations, we construct different graph structures, and multiple classification results are obtained, which brings more opportunities to represent the hyperspectral data correctly. Then, all the diverse-region results are further fused by a majority voting technique to improve the final performance. Finally, numerical experiments on two benchmark datasets are provided to demonstrate the superiority of the proposed DRHy-ChebyNet method to the other state-of-the-art methods.

Published: June 2022

Aiming at the high efficiency of composite electromagnetic scattering analysis and radar target detection and recognition utilizing high-range resolution profile (HRRP) characteristics and high-resolution synthetic aperture radar (SAR) images, a near-field modified iterative physical optics and facet-based two-scale model for analysis of composite electromagnetic scattering from multiple targets above rough surface have been presented. In this method, the coupling scattering of multiple targets is calculated by near-field iterative physical optics and the far-field scattering is calculated by the physical optics method. For the evaluation of the scattering of an electrically large sea surface, a slope cutoff probability distribution function is introduced in the two-scale model. Moreover, a fast imaging method is introduced based on the proposed hybrid electromagnetic scattering method. The numerical results show the effectiveness of the proposed method, which can generate backscattering data accurately and obtain high-resolution SAR images. It is concluded that the proposed method has the advantages of accurate computation and good recognition performance.

In the composition of feed for cattle, the presence of toxins that are formed as a result of violations of the technology of harvesting and storage of feed is recorded. Aflatoxins, ochratoxins, zearalenone, T-2 toxin, DON (deoxynivalenol), fumonisin are isolated. Mycotoxins entering the blood have a rather negative effect on the body of cows, reducing their productivity and fertilizing ability. Under conditions of intensive milk production technology, the determination of toxins in feed when feeding highly productive cows is of particular importance. The purpose of the research was to establish the degree of influence of different dosages of feed sorbents on the productive and reproductive traits of cows. The research was carried out under the conditions of the breeding farm of Black-and-White breed in OOO “Barmino” in the Nizhny Novgorod region. The objects of research were cows of the first lactation of Black-and-White breed, and the subject of research was the dairy productivity of cows and their reproductive traits. The objectives of the research included a comparative study of the influence of feed additives “Provitol” and “Vetosporin-active” on the productivity and reproductive traits of cows. In the concentrate part of the feed, the excess of the permissible norm of the mycotoxins zearalenone by 2,5 times and ochratoxin by 4,2 times was revealed. It was found that the dairy productivity of cows and higher indicators of reproductive abilities were animals in the 4th experimental group, who have been received the largest amount of the feed sorbent “Vetosporin-active” 2 kg per ton of concentrated feed. In comparison with the analogues of other experimental groups, they have the best ease of calving, the absence of problems with the separation of the afterbirth and endometriosis, the optimal duration of the open days period and the minimum expenditures of sperm doses for effective insemination. It was recommended to use the feed sorbent “Vetosporin-active” at the dose of 2,0 kg per ton of feed as a feed additive in the main ration of highly productive cows to improve their reproductive and productive traits.

Feed additives in the feeding of growing animals are able to meet their nutritional needs for the manifestation of high productivity indicators, since their main purpose is to optimize the ration of animals for energy, protein, macro– and microelements, vitamins and biologically active substances in accordance with feeding standards. The purpose of the research was to increase the productive traits of steers of Hereford breed, taking into account the consumption, digestibility and use of feed nutrients when consuming the carbohydrate complex “Felucene” K 2-4 and K 2-6. Scientific and economic experiment was carried out in OOO “Berezovskaya farm” in the Pervomaisky area in the Tomsk region. The steers of Hereford breed were divided into 4 groups according to the principle of groups of analogues: the 1st control group received a ration without additives, and the experimental ones (2nd, 3rd and 4th) with additives that were administered according to the developed scheme. In the period from 6 months to one year of age the steers were fed the carbohydrate complex “Felucene” K 2-4 at a dose of 50, 100 and 150 g/head/day, and then up to one and a half years of age the carbohydrate complex “Felucene” K 2-6 at the dose of 100, 150 and 200 g/head/day, respectively, in groups. It was found that the maximum slaughter yield was recorded in animals of the 3rd experimental group, which was 60,9 %, and the minimum was in the 1st control group 59,6 %, the average values were in steers in the 2nd and 4th experimental groups. There was a similar distribution of groups by carcass yield.

Published: June 2022

Bendungan rockfill akan mengalami kondisi kritis pada awal pengisian waduk akibat terjadinya hydraulic fracture pada hulu inti bendungan. Hydraulic fracture (retak hidrolis) pada bendungan rockfill terjadi akibat tanah tidak mampu menahan tegangan tarik dari tekanan hidrolis. Tegangan tarik akan terjadi apabila tekanan air pori lebih besar dari tegangan efektif tanah. Tekanan air pori akan meningkat pada saat pengisian waduk dan akan mengurangi tegangan efektif tanah. Untuk menganalisis perubahan tekanan air pori dan tegangan efektif selama proses pengisian maka dilakukan pemodelan potensi hydraulic fracture. Pada studi ini, pemodelan potensi hydraulic fracture dilakukan dengan model tanah elastic-plastic untuk inti bendungan dan linear-elastic untuk filter dan rockfill dengan kondisi tanah unsaturated di mana koefisien rembesan merupakan fungsi Soil-Water Characteristic Curve (SWCC). Pemodelan dilakukan menggunakan software komputer SEEP/W untuk menganalisis rembesan dan SIGMA/W untuk menganalisis tegangan. Pada studi ini akan ditampilkan pola debit rembesan, kontur tekanan air pori, tegangan total, dan tegangan efektif pada hulu inti bendungan.

Pengaruh Kebijakan Pemerintah Terhadap Bisnis Konstruksi Indonesia
Authors: Tanne Yongki Alexander
Published: June 2022

Kenaikan anggaran infrastruktur pemerintah ditujukan untuk meningkatkan pemerataan pembangunan dan perbaikan konektivitas dengan harapan untuk mengejar ketertinggalan Indonesia terhadap penyediaan infrastruktur (APBN 2018). Hal ini sangat wajar karena memang tanpa pembangunan infrastruktur yang memadai maka pemerataan pembangunan dan pertumbuhan ekonomi secara nasional juga akan terhambat. Perlu dilakukan kajian lebih lanjut mengenai dampak dari pembangunan infrastruktur yang masif dilakukan pemerintah karena berdasarkan kajian awal diatas terlihat bahwa sesungguhnya belum ada pemerataan pembagian paket pekerjaan antara kontraktor besar, kecil dan menengah baik itu BUMN maupun swasta. Belum ada kajian yang komperhensif mengenai hasil pembangunan infrastruktur dan terbatasnya data yang dipublikasikan menyebabkan terbatasnya lingkup kajian dan umpan balik yang dapat diberikan kepada pemerintah sebagai regulator untuk melakukan perbaikan.Disisi lain, perlu dilakukan upaya-upaya pemerintah untuk membuat bisnis konstruksi di Indonesia berkembang dengan merata melalui perbaikan regulasi terkait pembagian kualifikasi dan klasifikasi maupun mengarahkan kontraktor kecil menjadi kontraktor spesialis.

Published: June 2022

Untuk memenuhi kebutuhan air irigasi (irigasi untuk lahan pertanian), debit air di daerah bendung harus lebih dari cukup untuk dialirkan ke saluran (utama-sekunder-tersier) yang telah disiapkan di lahan tanam. Kecepatan aliran air yang mengalir melalui saluran tersier dipengaruhi oleh kekasaran, kemiringan dan ukuran saluran yang dibuat, semakin besar koefisien kekasaran saluran irigasi maka semakin kecil laju aliran saluran irigasi tersebut. Sehingga mengurangi aliran air terutama pada saluran yang terbuat dari tanah. Pengaruh kekasaran saluran ini dinyatakan dalam suatu nilai yang disebut koefisien kekasaran (Manning). Faktor-faktor yang mempengaruhi koefisien kekasaran adalah konstituen dari permukaan basah saluran, sifat fisik tanah, ketidakteraturan saluran, vegetasi yang tumbuh di saluran dan faktor pengendapan dan gerusan di dalam saluran.

Modern rethinking of the past (for example of novel “Women in Berlin”)
Authors: Varetska S.
Published: June 2022

A complex problem is considered, which covers a set of issues related to therethinking of the historical past. In recent decades, there have been sometransformations, especially at the level of reception of the past, which allows usto speak of a slightly modified view of history and its reflection in fiction. A set ofissues related to a comprehensive study of a phenomenon of war in ananthropological dimension is considered. Special attention is paid to a feminineway of re-reading of the national and world history through the prism ofeveryday life and the private sphere of being. This approach demonstrates thespecifics of the female worldview through everyday life: corporeality and dailyroutine. A tragic experience of the war is analyzed using a large palette ofhuman reactions and models of behavior in a stressful non-routine situation.Not a factual history of the Second World War, but the true story of the Germanwoman Martha Gillers on the example of her diary "Woman in Berlin" is shown.
PECULIARITIES OF ARTISTIC COGNITION IN THE SPACE OF BERTOLT BRECHT'S CREATIVE WORLD
Authors: Astrakhan N.
Published: June 2022

The article analyses the main principles of artistic cognition within the creative world of Bertolt Brecht, considering it the subject, first of all, of the author's reflection. From the point of view of the artist, expressed in his critical articles and theoretical works of different years, the knowledge and depiction of life's truth should be recognized as the main artistic guidance corresponding to the challenges of the time. This concerns the truth of public life,the discovery of which meets as obstacles to artistic research the criminality of society, the unwillingness of an individual to see the actual situation of their existence, analyse their own mistakes, and work to correct them.

According to Brecht, the truth about other people and society can be revealed only if a person can realize and express the truth about themselves, no matter how unpleasant it may be. The analysis of Brecht's short story The Wounded Socrates not only allows us to outline the importance of life-saving utmost honesty in the process of self-understanding but also to reveal the connection of the writer's creative activity with the traditions of Europeanphilosophical literature rooted in the era of antiquity and genetically connected with Socratic dialogue.

The epic theatre was created by Brecht in order to direct the spiritual and intellectual work of the creators and recipients of the theatrical action intounderstanding the most painful and dangerous problems of the present, tomake this collective work a prerequisite for fundamental social changes. Such a qualitative change in the social coexistence of people in the historical space of the twentieth century should not have been a victory in war, but avictory over war, i.e. exposing its true essence, hidden motives, and its suicidal for the human and humanity nature. The artistic synthesis that becomes a prerequisite for Brecht's dramaturgical innovation contributed to it, based on a combination of realistic and modernist artistic principles, the possibilities of epic, lyrics, and drama.
Metaphrase and Paraphrase. Self-Translation as Exile Art
Authors: Koliada Oleh
Published: June 2022

The article regards the matter of translation and self-translation in view of 1) thetypology of translations: conservative, dialogical and radical and 2) the classicalmethodology of modern translation according to John Dryden: metaphrase,paraphrase and imitation. Translation, on the one hand, is conventionallypresented as a form of comparative majority literature, when one's ownexperience is a criterion and means of the complex comparison (explicitly,comparing textually and meta-textually, or implicitly, juxtaposing the textualaspects to the sum of knowledge about language in general), which works mosteffectively. from an abstract representation to a verbal description, when thetranslation is transformed into meta-text, correlating the original source and thetarget (translation) texts. Self-translation, on the other hand, is seen as a minoritysegment on the border of different systems – cultures, or social values, and whichhas their contradictory influence on authors, for whom practice prevails overtheory by analogy with the limitation of a personality in relation to a socialcommunity, when an alternative of correspondence is suggested, namely, themolding of the primary freedom of creation by the architectonics andrhythmic-syntactic organization of the source text, which intuitively stimulatesthe imagination and encourage figurative modulations in the target text, theso-called "obligatory freedom". Self-translation is exemplified by the linguisticstatus of Samuel Beckett and his bilingual texts, the central element of which isthe formality of action and communication, reinterpreted by the author'sinteraction with the text itself on the level of communication between texts, fillingthe vacuum of absurdity with inter-textual dialogue.

Authors: Abed Amira Hassan , Nasr Mona
Published: June 2022

Medical datasets reflect a great environment as they integrate analyses of structured and unstructured data that holds several benefits for medical sector. With a continues demand for implementing Electronic Health Records (EHRs), there is a relative requirement for utilizing data mining (DM) techniques to find out useful data, unknown patterns and inference rules from data stored in EHRs which help in a real-time decisions making process and prove-based practice for medical providers and experts. Business Intelligence (BI) is a technology able to process the huge data inside EHRs repository for enhancing the quality of medical delivery. DM is data processing techniques that considered a critical part of the BI platform. In this paper, we highlight significance of the BI integration with the EHRs to aid medical providers and professionals in real- time detection and prediction for several diseases. For more explanation, we apply BI technology with support of clustering technique as one of DM methods, for cancer surgeries prediction to prove the power of cooperating BI and EHRs in medical area.

Published: June 2022

Obesitas merupakan  salah satu  masalah kesehatan baik di dalam negeri maupun di luar negeri. Dari populasi penderita tekanan darah tinggi pada obesitas lebih tinggi dari penderita tekanan darah tinggi yang tidak obesitas. Obesitas diketahui merupakan salah satu faktor yang meningkatkan resiko tekanan darah tinggi. Penyakit ini sering ditemui pada usia lebih dari 50 tahun ke atas atau lansia. Tujuan penelitian mengetahui Hubungan  Obesitas  Dengan Tekanan Darah Tinggi.Desain penelitian menggunakan studi Analitik dengan pendekatan cross-sectional. Penelitian dilaksanakan Februari 2022 di Posyandu Lansia Desa Ngunut. Populasi semua lansia berjumlah 85 lansia. Dengan sampel 30 lansia. Pengambilan sampel dengan tehnik  purposive sampling. Pengumpulan data menggunakan instrumen berupa lembar observasi. Pengolahan data (editing, coding, scoring dan  tabulating), dan dianalisis dengan uji statistik Spearmann Rho dengan α = 0,05. Lansia di posyandu lansia Desa ngunut, Kecamatan ngunut, Kabupaten Tulungagung sebagian besar mengalami obesitas kategori berat, (60%) dan hampir setengahnya mengalami tekanan darah tinggi kategori berat (43,3%). Hasil uji statistik Spearmann Rho dengan nilai P value = .001 dengan α = 0.05 sehingga Ho ditolak dan H1 diterima yang artinya Ada Hubungan Obesitas Dengan Tekanan Darah Tinggi Pada Lansia Di Posyandu Lanjut Usia Desa  Ngunut Kecamatan Ngunut  Kabupaten Tulungagung. Berdasarkan pada penelitian ini didapatkan bahwa semakin berat kategori obesitas maka, semakin tinggi tekanan darah pada lansia. Hal ini karena banyaknya lemak yang menempel pada pembuluh darah dan menurunnya elastisitas pembuluh darah pada lansia menyebabkan tekanan darah cenderung naik. Oleh karena itu, pada lansia yang obesitas dengan tekanan darah tinggi disarankan menurunkan berat badan dan menjaga berat badan ideal.
