A Non-linear Autoregressive Exogenous Neural Network-based Predictor for Protecting the GPS Receiver's Tracking Loop from the Spoofing Attack
Authors: Tohidi S. , Mosavi Mohammad Reza
Published: October 2023

A vital part of people's daily life is the position, navigation, and time service provided by the Global Positioning System (GPS), which is always accessible globally. Consequently, the security of the GPS receivers is crucial. Occasionally, intentional and unintentional interferences cause GPS location issues. Spoofing attack is the most severe interference to the GPS receivers, which results in positional mistakes. This paper's goal is to defend against the carry-off spoofing attacks. In a carry-off spoofing attempt, the spoofer transmits signals whose code phase and carrier frequency parameters are strikingly close to the actual signal in order to change the correlation values generated in the tracking stage. Discriminator output values alter as correlation values change. As a result, the Pseudo Random Noise (PRN) code generator unit creates a local replica, which forces the tracking loop to follow the fake signal instead of the real one. It is proposed in this paper that when spoofing attacks occur, discriminator output values be generated independently of correlation values. Specifically, when a spoofing signal is detected, the conventional discriminator is replaced by a Non-linear Autoregressive Exogenous Neural Network (NARX NN)-based predictor. This strategy protects the tracking loop from the effects of the spoofing signal. The efficiency of the provided strategy was evaluated using three spoofing data sets. The results of the suggested mitigation method, the NARX NN-based approach, show that it mitigate spoofing attacks by an average of 95.82%.

Authors: Bagnall Anne-Marie , South Jane , Kinsella Karina , Trigwell Joanne , Sheridan Kevin , Harden Angela
Published: October 2023

Background
Interventions that engage communities have been shown to improve health and wellbeing in disadvantaged groups internationally, but there is little evidence on current community-led practice, particularly in relation to the process of community engagement. This paper presents a qualitative cross-case analysis of barriers & facilitators in six UK community engagement projects, using different models of community engagement.
Methods
The primary sampling criteria was the type of approach to community engagement, using a conceptual framework with four main groups: Strengthening communities; Volunteer and peer roles; Collaborations and partnerships; Connecting to community resources. Qualitative interview-based methods (semi-structured interviews and focus groups) explored community and professional perspectives in depth. Thematic analysis was used to analyse the data, building within-case studies before comparing findings and using an iterative process to build explanations in a cross-case analysis.
Results
Fifty-five people took part in the research. Prominent themes included barriers and facilitators to community engagement. Key themes related to successful community engagement were: trust within the community and between community members and service providers; respect for community members’ expertise; allowing sufficient time for relationships to establish and for outcomes to be seen; commitment of key people; and Flexibility.
Conclusions
This qualitative case study research found that in successful community engagement projects, community expertise is respected and valued, allowing community members to be fully involved and take ownership of the projects. Sufficient time should be allowed for this process. Flexibility and adaptation of project materials, protocols and role descriptions is important in overcoming barriers to community engagement.

Published: October 2023

Monocular depth estimation has a wide range of applications in the field of autostereoscopic displays, however, accuracy and robustness in complex scenes are still a challenge. In this paper, we propose a depth estimation network for autostereoscopic displays, which aims at improving the accuracy of monocular depth estimation by fusing Vision Transformer (ViT) and Convolutional Neural Network (CNN). Our approach feeds the input image as a sequence of visual features into the ViT module and utilizes its global perception capability to extract high-level semantic features of the image. The relationship between the losses is quantified by adding a weight correction module to improve model robustness. We conducted experimental evaluations on several public datasets, and the results show that AMENet achieves better accuracy and robustness than existing methods in different scenarios and complex conditions. In addition, we conduct a detailed experimental analysis to verify the effectiveness and stability of our method. In summary, AMENet is a promising depth estimation method that can provide higher robustness and accuracy for monocular depth estimation tasks.

Published: October 2023

To solve the problem of severe physical resource depletion in cloud data centers, a virtual machine placement method based on an improved sparrow search algorithm is proposed. Firstly, Chebyshev chaotic mapping and Levy flight disturbance strategy are integrated into the sparrow search algorithm to improve the allocation of population resources in the search space and increase the diversity of population search. In addition, a mapping encoding scheme is designed to map the virtual machine placement scheme into continuous position information, Finally, a cloud data center resource consumption model was established with the objective function of maximizing the utilization efficiency of physical machine resources. The simulation results show that this method has better performance in virtual machine migration and physical resource utilization, and the Service Level Agreement (SLA) violation rate is basically stable.

Published: October 2023

Wastewater containing heavy metal ions poses great harm to human health and the environment. The adsorption materials used in traditional adsorption methods, such as starch and cellulose, are prone to hydrolysis, causing secondary pollution to water bodies. Nylon@Fe3O4@PAA adsorption material is obtained by using nylon as a substrate, activating nylon with sodium carbonate/hydrochloric acid, depositing a Fe3O4 magnetic layer by coprecipitation, and grafting polyacrylic acid. The adsorption material is used to explore the effects of different conditions (adsorption material dosage, Cu2+ concentration, pH value, and adsorption time) on the adsorption efficiency, adsorption capacity, and total adsorption amount of copper ions through changing the adsorption conditions. The research results showed that the adsorption material dosage is 18.75 mg (suspension solution with a concentration of 62.5 mg/mL is added with 300 µL), the concentration of Cu2+ solution is 20.48 mg/L, the adsorption time is 60 min, and the pH value is 9. The optimal adsorption efficiency is 82.29%, the optimal adsorption capacity is 154.87mg/g, and the optimal total adsorption amount is 343.91 mg. After fitting thermodynamic and kinetic equations, the adsorption process of nylon@Fe3O4@PAA for Cu2+ ions dominated by chemical adsorption, with good adsorption rate and adsorption performance.

Published: October 2023

Fuzzy c-means (FCM) is an effective clustering algorithm, which has been successfully applied on many real-world applications. Although, FCM and its improvements have achieved considerable performance however, most of the FCM-based methods consider equal importance for all features and neglect the feature weights in the clustering processes. To deal with this issue, in this paper, two methods called Local Feature Weighting FCM method (LFWFCM) is proposed and Robust Local Feature Weighting FCM (RLFWFCM) are proposed. RLFWFCM employs a non-Euclidian and robust metric in its process to overcome the presence of noise or outliers in data. Also pure mathematical analyses are provided to show the convergence properties of these methods. Also, these methods have been applied on the Hadoop platform by mapping reduction programming method. To assess the effectiveness of these methods, several experiments are performed on both real-world and synthetic datasets. The obtained results demonstrate the effectiveness of the proposed methods in comparison with some baseline and state-of-the-art clustering methods.

Published: October 2023

IBS/CAPP in South Korea is home to multiple active axion search experiments using cavity haloscopes that operate within the frequency range of 1-6 GHz. The haloscopes convert axions to photons, resulting in an output power of about 10-24 to 10-22 W. To detect such a small signal amidst noise, quantum-limited noise amplifiers and ultra-low-temperature environment (∼10 mK) are required for all critical read-out components to minimize noise from all of active and passive lossy components. Additionally, operating at low dissipation levels is necessary to maintain the haloscope and amplifier at a temperature of 25-40 mK. Our primary objective is to achieve the highest possible scanning-frequency speed, which includes the time for maintenance and system calibration.
For the CAPP-MAX flagship experiment, we achieved a record speed of 3 MHz/day for the DFSZ-level axion sensitivity during uninterrupting measurements. This paper presents the development and operation of low-noise amplifiers for five haloscope experiments targeting different frequency ranges and provides design, operational, and performance details of the amplifiers.

Authors: Abdullah Arshad Mohammad
Published: October 2023

Background: Vegetables play a crucial role in human nutrition, forming a significant part of our daily diet. Nevertheless, the consumption of vegetables stands out as a primary pathway for the transmission of intestinal parasites to humans.
Objective: The objective of this study was to explore the presence of parasitic helminths responsible for contaminating vegetables in Duhok city, Kurdistan Region of Iraq.
Methods: In the present study, spanning from June 2021 to August 2021, which 126 samples of fresh vegetables, including Coriander, Dill, Lettuce, Pepper, Parsley, and Radish were collected from various places in Duhok city. These samples underwent microscopic examination to investigate the presence of parasites.
Results: The study revealed that 15.9% of the vegetables were contaminated with parasitic helminths, but there was no significant difference between the contaminated and non-contaminated vegetables, as indicated by a p-value of 0.628. Three varieties of parasitic helminths were identified in the vegetable samples, namely Ascaris lumbricoides (7.9%), Enterobius vermicularis(6.3%), and Hymenolepis nana (2.4%). The highest incidence of parasitic helminths contamination was observed in Parsley (23.8%) and Lettuce (20%), while Pepper showed a lower contamination rate of 4.8%.
Conclusion:This study has revealed a moderate rate of contamination of fresh vegetables with parasitic helminths. This contamination can potentially serve as a significant factor in the transmission of pathogenic intestinal parasites.
Reliability of multi-story buildings with load-bearing structures of cast reinforced concrete during the construction period
Authors: Komarov A. K.
Published: October 2023

Reinforced concrete is considered to be one of the most reliable structural materials. For this reason, it is widely used for mass construction of buildings and structures in Russia and other countries. In particular, reinforced concrete is predominantly used in the construction of multi-story buildings of any design in all Russian regions at any time of the year. Improvements in technologies, construction management and mechanical aids increase the industrialization of construction. Although this fact is generally regarded as extremely positive, it reduces the time allowed for concrete to gain the required strength characteristics. Sometimes, loads from upper structures of buildings are applied to fresh, immature concrete. Obviously, specific technical decisions are required to intensify the concrete hardening process and create favorable temperature and humidity conditions for its curing. Russian science and practical experience have a large arsenal of effective technical means for solving these problems. However, these means are reluctantly applied in practice, since this entails a rise in construction costs, even though slight. This creates a situation when unacceptable loads from the higher floors are applied to the lower floors of the building. The structures perceive static loads rather than dynamic ones, including seismic loads, with an inertial mass of tens of tons, thereby causing a risky situation at the site. This happens en masse. The problem is even more complicated in winter time. During the period of concrete thawing in spring, the entire facility can be classified as being in a metastable state. The paper considers the production circumstances associated with the above situations and proposes recommendations for their prevention.

Dark matter from the centre of SU(N)
Authors: Frigerio Michele , Grimbaum-Yamamoto Nicolas , Hambye Thomas
Published: October 2023

A dark sector with non-abelian gauge symmetry provides a sound framework to justify stable dark matter (DM) candidates. We consider scalar fields charged under a SU(N)SU(N) gauge group, and show that the centre of SU(N)SU(N), the discrete subgroup Z_NZN also known as NN-ality, can ensure the stability of scalar DM particles. We analyse in some details two minimal DM models of this class, based on SU(2)SU(2) and SU(3)SU(3), respectively. These models have non-trivial patterns of spontaneous symmetry breaking, leading to distinctive phenomenological implications. For the SU(2)SU(2) model these include a specific interplay of two DM states, with the same interactions but different masses, and several complementary DM annihilation regimes, either within the dark sector or through the Higgs portal. The SU(3)SU(3) model predicts dark radiation made of a pair of dark photons with a unique gauge coupling, as well as regimes where DM semi-annihilations become dominant and testable.

Scaffolds are devices with interconnected pores that favor cell interaction and proliferation. They play a significant role in tissue engineering, as they mimic the conditions of tissue production in vivo. The aim of this study was to synthesize scaffolds of chitosan, collagen, and Jatropha mollissima by lyophilization and characterize their chemical/biodegradability and morphological properties. For that, techniques of optical microscopy, infrared spectrometry, biodegradation test, and degree of swelling were performed. A 2% (m/v) chitosan/collagen (1:9) in lactic acid solution was produced. Then, Jatropha mollissima crude extract was added to this solution in different proportions of mass (5, 10, and 15%). Optical microscope images indicated the three-dimensional network formation with interconnected pores and predominantly lamellar shape. Through infrared spectrometry, characteristic bands indicated a physical mixture. Also, the swelling degree of all samples was proportional to the amount of Jatropha mollissima extract with the highest percentage of 1852%. Biodegradation test also revealed a proportional ratio between the amount of sap used and the degraded percentage with the lowest value of around 35% in 28 days. In conclusion, it can be inferred that the scaffolds produced show potential to be used in tissue engineering as dressings.

In this research, biogas is produced from Palm Oil Mill Effluent (POME) by fermentation of cow dung using a stirred reactor and purified by various CO2 and H2S removal techniques. The variables in this study were: composition of cow dung (55%, 60%, 65%, 70%, 75%, 80% w/w), amino acid composition (0.5%, 1%, 1.5% w/w) and length of fermentation time (2, 6, 10, 14, 16 days). The fixed variables were stirring speed (100 rpm), temperature (30oC) and reactor volume (100 L). This research also investigated the effect of using a lime packed reactor on the purity of methane gas. From the results of first stage of fermentation, it was found that the optimum composition of cow dung-POME was at 60% and the fermentation time was 14 days. In the second stage of fermentation using optimum results at first stage compared to fermentation of cow dung without POME, the results of measuring the gas pressure produced in 60% cow dung-POME fermentation were 17.5 Psig greater than fermentation of cow dung without POME of 15 Psig.

Published: October 2023

The rise of construction projects and population growth, followed by the expansion of industry and any other sectors such as housing estate, offices, and transportation, can lead to not only economic growth but also negative impacts such as air pollution, including nitrogen dioxide (NO2) pollutants. According to KEP-45/MENLH/10/1997, air pollution can be determined by The Pollutant Standards Index (PSI). The statistical analysis result employing the multivariate ANOVA test with the Anderson-Darling method showed the impact of NO2 concentrations on four location points over two years. Meanwhile, the data result of PSI revealed a high level of ambient air NO2 in Lampung Barat Regency, particularly at the monitoring point of offices. On the other hand, in Way Kanan Regency, the level of ambient air NO2 tends to be safe and secure at the monitoring point of industry and transportation. The factor of sampling location and technique (stage 1: dry season, stage 2: rainy season) did not give a significant effect on the NO2 level due to a p-value ≥ 0,05. However, the sampling point (of monitoring) influenced the NO2 level for p-value ≤ 0,05 in Lampung Barat and Way Kanan Regency in 2019-2020 which was still claimed as safe and secure based on PP No. 41 in the Year 1999, which sets the required limit at 100 g/m3.

The rapid development of technology today cannot be separated from the role of various kinds of machines to produce or increase the use value of an item. The more the engine operates, the more lubricant is used. Lubricants are included in the category of B3 waste (Toxic Hazardous Materials) so that they have a negative impact on the environment. Nearly 50% of all mineral lubricants enter the environment and cause irreparable environmental damage due to direct contact with water and soil. One of the efforts that can be done to reduce the B3 content in used lubricants is adsorption using a porous adsorbent. This study aims to see the relationship between the physical and chemical properties of the adsorbent with the physical and chemical properties of the adsorbate. This research was conducted by studying the literature of scientific articles with related topics. The results showed that some contaminants such as organic compounds, inorganic species, soot, hydrocarbons, and ash can be adsorbed with various adsorbents, namely modified sawdust, bentonite, fly ash, activated carbon, activated alumina, and zeolite Y derived from kaolin.

Published: October 2023

Fresh water is vital for the survival of life. Rivers are the primary source of freshwater supply. However, over the past few decades, challenges concerning the sustainability of rivers and maintaining their water quality have become countless. Due to rapid and unrestrained advancements, the river ecosystem becomes imbalanced. To assess and predict water quality from the real data collected, it becomes necessary to devise ways to interpret and analyze the data efficiently. The present work deals with the development of a water quality index based on a fuzzy approach for predicting the water quality of the river Yamuna. The most contaminated stretch of the river through Delhi has been taken up for this study. The proposed methodology is elementary, simple, effective, and flexible in assimilating uncertainties involved in complex water management problems. The suggested index involves the most dominant parameters and can act as a practical tool for routine water quality assessment. The outcomes of the study give pronounced facts to water authorities about the awful condition of the river Yamuna in Delhi.

We have reviewed the potential use of bioactive peptides in the treatment of gastrointestinal (GI)
malignancies, which are a significant cause of morbidity and mortality globally. Conventional therapies, such
as surgery, chemotherapy, and radiotherapy, are associated with numerous side effects that may lead to longterm
complications. Bioactive peptides are short-chain amino acids that can be extracted from natural sources
or synthesized, and they have various potential health benefits, including anti-inflammatory, anti-hypertensive,
antioxidant, antimicrobial, and anti-cancer properties. Bioactive peptides can be acquired from animal or plant
sources, and can be classified based on their function, such as ACE-inhibiting, antimicrobial, and electrolyte-
regulating peptides. Recent studies have demonstrated the promising role of bioactive peptides in tumor
suppression, especially when combined with conventional therapies. In this study, we have reviewed the beneficial
properties of bioactive peptides and their role in suppressing tumor activity. The mechanisms of bioactive
peptides in tumor suppression are discussed. We have further reviewed the findings of preclinical and clinical
studies that have investigated the application of bioactive peptides in the treatment of GI cancers. This review
highlights the potential use of bioactive peptides as a promising treatment method for GI malignancies to
increase the quality of life of GI cancer patients.

Published: October 2023

Plants have been used since the earliest times to manage various diseases, and many
of these plants are being used as conventional remedies for various disorders today. Biologically
active ingredients isolated from medicinal plants and extracts are receiving a lot of attention these days, partly because modern-day medication has a lot of side effects and somewhat because
pathogenic microorganisms are becoming more resistant to antibiotics and many other treatments. Artemisia is the broadly dispersed genus of the family Asteraceae and encompasses almost five hundred species. Amongst these species, Artemisia absinthium L. is a familiar herb
called Wormwood in English and Urdu, generally known as Afsanteen. In history, this species
was recognized as important, and in old Europe, it was called “the most important master
against all exhaustion”. A. absinthium has various benefits in treating pathological conditions
such as gastric problems, fever, inflammation, and urinary disorders. The official European medicine uses A. absinthium in both allopathy and homeopathy. The herb was used to treat bladder
diseases, anemia, helminthiasis, insomnia, fever, and trouble healing wounds and to treat gastrointestinal disorders in Asian and European traditional medicine. Mono and sesquiterpenes are the
major pharmacologically active constituents of A. absinthium. Wormwood is a valuable resource
of chemically new constituents and requires comprehensive screening approaches to emphasize
the phytoconstituents and pharmacological actions at the molecular level. The core focus of this
review is to provide complete information about the scientific evidence-based pharmacological
activities, traditional uses, and phytoconstituents from A. absinthium. The collation of literature
has been done by using references from main databases such as PubMed, Research gate, Scopes,
Science Direct, Google Scholar, Chemical Abstracts, Phytochemical and Ethnobotanical Databases, Medicinal and Aromatic Plants Abstracts, classical books, and pharmacopeias.

Diabetes Mellitus (DM) is one of a group of metabolic diseases characterized by hyperglycemia caused by a disturbance in insulin so that blood glucose levels increase. Prevention of absorption of blood glucose by the intestine can be done with the help of the enzyme α-glucosidase. Based on the results of phytochemical tests, it is known that the methanol fraction of sungkai leaves contains flavonoid compounds. The Fourier Transform Infra-Red (FTIR) spectrum showed that the isolates had phenolic O-H groups (3,354.53 cm1 , 1,359.28 cm-1 ), aromatic C=C group (1,615.48 cm-1 ), C-O-C ether group (1,046.60 cm-1 ) and aromatic C-H group (822.21 cm-1 ). In vivo antidiabetic activity test was carried out using test animals of white male mice which were induced by alloxan. Antidiabetic testing was carried out using 6 treatment groups with glibenclamide, Na-Carboxymethyl cellulose (NaCMC) 0.5%, dose 175 mg/kgBW, 350 mg/kgBW, 700 mg/kg Body Weight (BW) and isolates 2 mg/kgBW. The results showed that the methanol fraction of sungkai leaves had the best antidiabetic activity at a dose of isolate and 700 mg/kgBW which was able to reduce blood glucose levels by 42.20% and 42.00%. In vitro antidiabetic testing through αglucosidase enzyme inhibition mechanism did not show any antidiabetic activity at concentrations of fractions 5, 10, 25, 50 and 100 ppm.

Published: October 2023

Ralstonia solanacearum, the causal agent of bacterial wilt disease is worldwide in distribution, and results in serious economic losses, particularly in the tropics. Detection and characterization of microorganisms by Fourier transform infrared spectroscopy (FTIR) technique promises to be of great value because of the method’s inherent sensitivity, small sample size, rapidity, and simplicity. In this study, we used FTIR spectroscopy for the characterization of Ralstonia solanacearum. The bacteria were grown on Nutrient Agar (NA) at 28°C for 48 hours. The colonies of Ralstonia solanacearum on nutrient agar medium were smooth circular, raised, and dirty white. Cultures of bacteria were identified by molecular methods using PCR techniques. The DNA was amplified using a specific primer pair, 759f/760r (forward primer: 5'- GTCGCCGTCAACTCACTTTCC 3’, reverse primer: 5'-GTCGCCGTAGCAATGCGGAATCG-3’). The PCR produced a single band of 280 bp from the isolated DNA of cultured bacteria. Bacterial spectra were obtained in the wavenumber range of 4000–400 cm-1 using FTIR spectroscopy. The identification of cell wall constituents in region 3000–2800 cm-1, the proteinaceous structure of bacteria in region 1665–1200 cm-1, and the fingerprint of bacteria in region 1200-800 cm-1 are all part of the spectra analysis in this study.

One of the potentials of Bacillus cereus bacteria is as an inducer of systemic resistance in plants against plant diseases. FTIR spectroscopy is a traditional method extensively utilized in the pharmaceutical industry, since it is fast, non-destructive, and requires minimal sample preparation. In this study, the indicators that were effectively discovered were the functional groups that compose carbohydrates and lipids. The absorption region to be analyzed for the functional groups that compose carbohydrates is in the wavenumber region of 1200-800 cm-1, whereas the functional groups that compose up lipids are in the wavenumber range of 3020-2800 cm-1 and 1800-800 cm-1. The signal produced on the spectral signature of B. cereus isolates revealing the functional groups that compose carbohydrates is at the absorption values of 1185, 1132, 1122, 1098, 1078, 1056, 1010, and 973 cm-1. This is analogous to the notion that the cell wall of B. cereus is composed of peptidoglycan which contains carbohydrates. While the absorption values that indicate the functional groups that make up lipids are 2969, 2955, 2925, 2870, 2846, 1759, 1733, 1471, 1455, 1234, 895 cm-1, which according to the literature suggests that the body structure of B. cereus contains 2-3% of the dry weight of bacterial cells and consists of neutral lipids and phospholipids.

In this work, we apply a multiphysics approach to fused deposition modeling to simulate extrusion and solidification. Restricting the work to a single line scan, we focus on the application of polylactic acid. In addition to heat, momentum and mass transfer, the solid/liquid/vapor interface is simulated using a front-tracking, level-set method. The results focus on the evolving temperature, viscosity, and volume fraction and are cast within a set of parametric studies, to include the printing and extrusion speed, as well as the extrusion temperature. Among other findings, it was observed that fused deposition modeling can be effectively modeled using a front-tracking method (i.e. the level set method) in concert with a temperature dependent porosity function. The use of the level-set method for discriminating the phase change interface in this context is relatively new and offers considerable advantages over existing methods.

The experiment was conducted to study the effect of adding local and Egyptian
palm pollen to broiler feed on some blood biochemistry parameters and intestinal
flora by using 400 broiler chicks Ross308 one-day age and divided into 8 treatments and 5 replicates. Each treatment includes 50 birds, 10 birds per replicate.
Palm pollen was added to the diet from the first day till the end of the experiment
(42 days). The first treatment was a control without any addition. The second and
third treatments included the addition of 1 and 2 kg/ton from local palm pollen,
while the fourth and fifth treatments added 1 and 2 kg/ton from Egyptian palm
pollen As for the sixth treatment, the addition of 1 kg of local palm pollen/ton +1
kg of Egyptian palm pollen/ton as well as the seventh treatment 1 kg of local palm
pollen/ton + 2 kg of Egyptian palm pollen/ton and the eighth was the addition of 2
kg of local palm pollen / ton+1 kg Egyptian palm pollen/ton. The experiment results showed significant differences (p<0.05) in the concentration of protein, albumin, globulin, glucose, Cholesterol and LDL when adding palm pollen compared to the control treatment. There was a significant increase in HDL in the
treatments added with palm pollen and the activity of liver enzymes ALT and
AST. There was an improvement in the antioxidant status, as there was a decrease
in the levels of malondialdehyde and an increase in the levels of GSH glutathione
in the palm pollen supplementation treatments compared to the control treatment.
Also, a significant decrease was recorded in additional treatments in the numbers
of E. coli bacteria and a significant increase in additional treatments in the numbers
of Lactobacilli compared with the control treatment.

Research on Cohen’s Marxist View of Equality
Authors: Yuan Ze
Published: October 2023

Cohen’s Marxist view of equality is formed on the basis of criticizing liberals and classical Marxism. On the one hand, he opposes the equality thought of Rawls and Nozick, and on the other hand, he tries to establish a realistic and standardized Marxist view of equality. In addition, Cohen, while criticizing the arguments of the liberals, also constantly rethinks the classical Marxism on the concept of equality, and reconstructs the Marxist concept of equality to a certain extent. Dialectically speaking, although Cohen’s view of equality differs from the Marxist view of equality, it still plays a vital role in the construction of an equal society and the development of equality thought.

Objective: To understand the mental health status and social support status of the elderly population in rural areas after 5.12 earthquake disaster and its influence on mental health status. Methods: 195 rural elderly in Pengzhou mountainous areas (Longmen mountain town, Ci feng town, Xiao yudong town, Tongji town, Bailu town, Xinxing town) 6 towns were investigated by random questionnaire, self-made demographic scale, Symptom self-rating Scale (SCL-90) and Social Support scale. Results: (1) The social support status of the rural elderly was good, but the mental health levels were significantly lower than the national norm (p<0.001), and the prevalence of psychological symptoms was 6.16% (12/195). (2) The total score of social support and scores of subjective support were negatively correlated with the depression factors of mental health (r subjective support = -0.167 p<0.05, r social support total mark = -0.168 p<0.05), and the subjective support had a predictive effect on depression (β=-0.086, p<0.05). Conclusion: Although the detection rate of mental health of rural elderly in the five years after the earthquake is not high, the score of all dimensions of scl-90 is significantly lower than the norm, and the good social support will alleviate mental health problems.
