Authors: Kulkarni Pallavi V. , Thakre Kalpana S.
Published: June 2024

Sentiment Analysis plays an important role in developing AI applications involving human language and sense. Language-specific Sentiment Lexicon is important to accelerate Sentiment Analysis. Marathi is a morphologically rich but low-resource Indic Language. The language has a very strong grammatical base showing high resemblance to the human body. The paper elaborates on issues like Lexicon basics, word embedding, and Neural Network Models in the process of Lexicon Construction. Existing databases that are useful as seed databases are enlisted. A detailed study of various methods of Lexicon Construction is done. The methods highlight that Sentiment Neural Embedding is required and contextual information plays a vital role in detecting the polarity of a single word or document. The hybrid approach which uses lexicon-based features for deep learning provides better understanding of sentiment analysis. A method is proposed for MSL construction and sentiment analysis of Marathi text. Natural Language Processing Research for Indic Language is its boom. For Marathi, the efforts are seen. Considering the depth and scope of this language, more resource creation is a must for its revolutionization.

Reinforcement Learning for Adaptive Cognitive Sensor Networks
Authors: Nazeer Shaik  , Abdul Subhahan Shaik
Published: June 2024

In this paper, we propose an adaptive cognitive sensor network (CSN) system utilizing reinforcement learning (RL) to optimize network performance dynamically. The RL-based system adjusts key parameters such as transmission power, channel selection, and data scheduling based on real-time environmental feedback, thereby enhancing energy efficiency, spectrum utilization, and data accuracy. A Q-learning algorithm is employed to train the RL agent, which operates under an ϵ-greedy policy to balance exploration and exploitation. Comparative analysis with traditional static and rule-based systems demonstrates significant improvements across all key performance metrics. Future enhancements are suggested, including advanced RL techniques, transfer learning, and real-world deployments, highlighting the potential of RL in transforming CSNs into more intelligent, efficient, and resilient networks

Published: June 2024

The need to decarbonize transportation is becoming more urgent, which has increased interest in essential energies like hydrogen. Hydrogen internal combustion engine vehicles (HICEVs) present a potentially reciprocal strategy, although hydrogen energy cell vehicles (FCEVs) have received a lot of attention. This essay offers a critical analysis of HICEV technology as it exists today, highlighting its potential, difficulties, and role in the transition to sustainable mobility. We start by describing the fundamental ideas behind HICEVs and stressing the similarities and contrasts with gasoline-powered vehicles. We also delve into the environmental advantages of HICEVs, highlighting their almost zero tailpipe emissions and implied carbon neutrality based on the types of hydrogen products they produce. However, we also acknowledge that HICEVs have drawbacks, such as reduced efficiency when compared to FCEVs, more complex engineering, and logistical difficulties with hydrogen

Authors:   The Korean Career·Entrepreneurship & Business Association, Ha Kyusoo , Cho Jin A
Published: June 2024

In the early age of the MZ generation, the number of N workers participating in side projects in addition to jobs that earn main income to prepare for retirement is increasing. Some of them are increasingly interested in starting their own businesses as they prepare for retirement. At this point, this study conducted an online survey of the MZ generation among prospective founders nationwide. The collected data were selected and valid 272 copies were obtained and used for analysis. Correlation verification was analyzed using Pearson correlation. As a result of the division, first, autonomy among personal characteristics was found to have a significant effect on entrepreneurship intention. On the other hand, it was found that creativity and conductivity were not significant among personal characteristics. Second, the role model was found to have a significant influence on entrepreneurship intention. Third, among anxiety, workplace anxiety had a significant effect on entrepreneurship intention, but future anxiety was not. In the mediating effect test of entrepreneurship opportunity recognition, the mediating effect of entrepreneurship opportunity recognition was found between creativity, conductivity, autonomy, and entrepreneurship intention among individual characteristics. It was found that there was a mediating effect of entrepreneurship opportunity recognition between the relationship between the role model and entrepreneurship intention. On the other hand, among anxiety, recognition of start-up opportunities was found to have no mediating effect between the relationship between job anxiety, future anxiety, and start-up intention. These findings could present a differentiated perspective on the start-up intention of the MZ generation. In addition, by providing important clues to raising awareness of start-up intention, it will be possible to provide a solution to the development of a program to recognize start-up opportunities for the MZ generation.

On the wordhood of Josa of Korean in a typological perspective
Authors:   Morphology, Choi Hyung-yong
Published: June 2024

The purpose of this paper is to measure the wordhood of Korean Josa based on the typological research established in Choi(2021, 2022). As noted, there have been some views that consider Korean Josa as ‘syntactic affixes’ or ‘clitics’. What they have in common is that Korean Josa have phonological dependencies, but syntactically function as words. In this paper, I examined 44 Korean Josa on a 5-point scale according to the criteria for distinguishing between affixes and words proposed by Choi(2022), and found that the average score was 3.78, indicating a high degree of wordhood. The highest score is 4.18 and the lowest score is 3.45, so it is very important to note that none of them appears to be closer to affixes than words. Focusing on each Josa, using the school grammar system's classification of Josa, I could see that the average score is higher for ‘case marking’ than for ‘conjunctive’ or ‘adding special meaning’, but the difference is very small and negligible. In terms of criteria, I categorized them into semantic, syntactic, morphological, and phonological ones, and the scores decreased in this order. Only in the phonological criteria, affixhood scores are higher than wordhood score, which are due to the dependent nature of Korean Josa. The above results are sufficient to empirically prove that Korean Josa can be considered as words in a typological perspective.

Authors: Offor John I. , Madu C.N. , Ugochukwu U.C. , Anyanwu D.C. , C.P. Poly-Mbah , E.C Nwokorie
Published: June 2024

INTRODUCTION Heavy metals generally have been of remarkable concern to researchers and scientist. Lead is one of the heavy metals with no biological value to plants, animals, and humans. Hence like other heavy metals in such class (Cadmium, Arsenic, and mercury) could be toxic even in little concentrations. Lead is described as the most important toxic heavy metal in the environment. Due to its important physico-chemical properties, its use can be retraced to historical times. Due to its non-biodegradable nature and continuous use, its concentration accumulates in the environment with increasing hazards (Nas and Ali, 2018; Babu et al 2021, Offor et al 2024). In plants, lead affects several processes, including photosynthesis. Same plants however can take up lead and serve as decontaminating organism for lead in soil. Several researches have established high concentrations of Lead and other heavy metals in plant tissues, both edible and non-edible parts (Offor et al, 2020a, Offor et al, 2020b) .

Data collection techniques used were observation, interviews, and documentation. Data analysis used in this research is the Miles & Hiberman model, which consists of stages 1) data reduction, 2) data presentation, and 3) conclusion drawing and classification. This study found that there are still some teachers who rarely apply technology-based learning media, such as interactive PowerPoint media, in the learning process in the classroom, causing boredom and a lack of enthusiasm for learning. However, with the application of interactive PowerPoint media, students are increasingly excited and interested in the learning process, so it has a good impact on learning activities, which is characterized by an increased sense of student responsibility for the tasks assigned and fluency in communication. The application of interactive PowerPoint media by the homeroom teacher of grade 4 SDN Simoketawang in the learning process is able to improve the collaborative attitude of students in the classroom in accordance with collaborative indicators. The achievement of collaborative indicators in students has implications for the increase in student scores, which were originally below the minimum completeness criteria (KKM) to an average above the minimum completeness criteria (KKM).

Mechanisms of Tolerance in Metal-exposed Brown Algae and the Importance of Monitoring Studies: A Review
Authors: Montenegro Diana
Published: June 2024

Marine habitats are under threat from the continued release of contaminants into waterways, and monitoring becomes crucialto future management decisions and regulations to protect these environments. A key aspect of this monitoring is the choiceof a marine species that is able to cope with this pollution, and the tolerant species exhibit more relevant ecological responses.These species-responses are called biomarkers of tolerance and are tested using a variety of measurements that reflect exposureto chemicals. Marine brown macroalgae can be found in a wide range of marine environments, including those with high metalpollution and they are widely used in monitoring programs. Mechanisms of tolerance are vital to the survival of this group ofmacroalgae in polluted habitats, but these mechanisms have not yet been reviewed. The aim of this critical review article isto summarize the historical information available regarding metal tolerance in marine brown macroalgae. We review studiesabout tolerance mechanisms in marine brown macroalgae exposed to metals, conducted both under experimental conditionsand in the field. Also, bibliometric analyses are used to identify the most relevant investigations, country contributions andgaps in knowledge on the topic. Results showed that the principal extracellular tolerance mechanisms described for marinebrown macroalgae are physical exclusion, exudated ligands, and metal-binding to the cell wall. Epiphytic microorganismswere also found to be capable of accumulating a given metal. Internally, metallothioneins and phytochelatins were importantchelators; furthermore, antioxidant responses may increase metal tolerance. Omics analyses were used to reveal the internalmechanisms used by these macroalgae. Biomarkers of tolerance have occasionally been used in monitoring studies, providingadditional information regarding tolerance to complex chemical mixtures found in the field. Future studies should make use ofthese biomarkers to improve our understanding of metal-tolerance strategies.

Published: June 2024

Erzurum cheese halva is a traditional food registered with a geographical indication with its own taste and flavor, which is produced with saltless fresh civil cheese, fresh cream and flour mixture. This study was conducted to investigate the changes in the physical, chemical and microbiological properties of Erzurum cheese halva in different packaging and storage tempareture. The produced cheese halva samples were stored for two months in two different packaging methods (aerobic and vacuum packaged) and at three different storage temperatures (room temperature, +4℃ and -18℃). Some microbiological, chemical, physicochemical and sensory analysis of cheese halva samples were investigated during storage period. Furthermore, the dry matter, ash, protein, fat, salt and aw contents of cheese halva samples were determined on the 0th day of storage. The most obvious sign of deterioration were moldiness on aerobic packaged samples both the room temperature and +4℃ stored, and they were spoiled on the10th and 15th day of storage, respectively. It was observed that the acidity has increased and consumability has decreased in vacuum packaged samples stored at +4°C. Although neither chemical nor microbiological deterioration occurred in the vacuum packaged cheese halva samples stored on -18°C, negatively affects in the fibrous structure of the product and reduces the overall acceptability of the product. For this reason, future studies must be carried out that is necessary to search for more suitable packaging methods (e.g. modified atmosphere packaging) to protect the product's typical textural structure during the shelf life.

Authors: Alharbi Reem , Almosallam Osama , Albastaki Sara , Almughamsi Asim , Alsanea Nasser
Published: June 2024

BACKGROUND:

Anastomotic leakage (AL) represents a severe complication after rectal surgery, leading to significant morbidity, mortality, and increased healthcare costs. Despite improvements in surgical methods and perioperative care, the challenge of AL persists.

OBJECTIVES:

Explore the impact of body mass index (BMI) on the risk of AL following curative treatment for rectal cancer, providing insight into its predictive value.

DESIGN:

Retrospective review

SETTINGS:

Data were collected from a single tertiary center, emphasizing the specialized postoperative outcomes in a high-care setting.

PATIENTS AND METHODS:

The study population was comprised patients who underwent sphincter-saving surgery combined with neoadjuvant chemoradiation for rectal cancer from 2001 to 2011. Patients with anastomotic stenosis were excluded.

MAIN OUTCOME MEASURES:

The primary outcome investigated was the occurrence of AL post-surgery. Secondary outcomes included the assessment of local cancer recurrence rates within the AL group.

SAMPLE SIZE:

224; 13 excluded

RESULTS:

Of 237 patients who underwent surgery, 13 with anastomotic stenosis were excluded from this study. Of the remaining 224, 15 individuals (6.3%) developed AL. A potential association between higher BMI and increased AL risk was identified. Additionally, the study noted a higher incidence of local rectal cancer recurrence in the group that developed leakage.

CONCLUSION:

The findings suggest BMI as a significant predictive factor for AL after curative rectal cancer treatment. This emphasizes the need for heightened awareness and possible preoperative counseling for obese patients regarding their increased risk of postoperative leakage.

LIMITATIONS:

The study was retrospective with all the inherit biases of such studies. The sample size was small and this may have introduced a type 2 statistical error.
Clinical outcomes of corticosteroid administration for acute respiratory distress syndrome in adults based on meta-analyses and trial sequential analysis
Authors: Wu Di , Li Yue , Dong Shao-Hua , Gao Yue
Published: June 2024

BACKGROUND:

Acute respiratory distress syndrome (ARDS), which results in lung injury as a consequence of sepsis and septic shock, is associated with severe systemic inflammation and is responsible for a high worldwide mortality rate.

OBJECTIVE:

Investigate whether corticosteroids could benefit clinical outcomes in adult with ARDS.

METHODS:

A comprehensive search of electronic databases Ovid MEDLINE, Ovid EMbase, and Cochrane Library from their inception to 7 May 2023 was conducted to identify studies that met the eligibility criteria, including only randomized controlled trials. The study was performed in accordance with the Preferred Reporting Items for Systematic Reviews and Meta-Analyses (PRISMA) guidelines and the methods of trial sequential analysis.

MAIN OUTCOME MEASURES:

Mortality rates, including including the 14-, 28-, 45-, and 60-day mortality, hospital mortality, and intensive care unit (ICU) mortality.

SAMPLE SIZE:

17 studies with 2508 patients.

RESULTS:

Data relating to mortality at 14, 28, 45, and 60 days were not significantly different when treatments with corticosteroids and placebo were compared. In terms of hospital and ICU mortality, the mortality of those who had received corticosteroids was significantly lower than that of those who had not. ARDS patients who received assisted ventilation benefited from corticosteroid therapy, as revealed by the significant difference in outcome days between those who received assisted ventilation and those who did not. Corticosteroid had significantly more days free from mechanical ventilation, ICU-free days, and MODS-free days during the first 28 days, but not more organ support-free days up to day 28.

CONCLUSION:

Although corticosteroid therapy did not reduce mortality rates at different observation periods, it significantly reduced hospital and ICU mortality. Administering corticosteroids to ARDS patients significantly decreased the days of assisted ventilation and time cost consumption. This study confirmed that long-term use of low-dose glucocorticoids may have a positive effect on early ARDS.

LIMITATION:

Risk of bias due to the differences in patient characteristics.
Association of TLR4 gene rs4986790 and rs4986791 polymorphisms with asthma susceptibility: meta-analysis and trial sequential analysis
Authors: Guo Nan , Tian Haokun , Song Tiangang , Peng Yu
Published: June 2024

BACKGROUND:

The current understanding of the correlation between TLR4 gene (toll-like receptor 4) rs4986790 and rs4986791 polymorphisms and asthma susceptibility is inconclusive, with studies and populations yielding conflicting results.

OBJECTIVES:

Evaluate this relationship using meta-analysis and trial sequential analysis (TSA).

PATIENTS AND METHODS:

Databases were systematically queried for relevant articles from the establishment of the database to 19 June 2023 adhering to predefined inclusion and exclusion criteria. Two authors independently conducted screening, data extraction, and quality evaluation. Meta-analysis and TSA were carried out using RevMan 5.4, StataMP 17.0, and TSA 0.9.5.10 Beta, with α=0.05. Subgroup analyses were conducted based on racial demographics. A sensitivity analysis was conducted employing a one-by-one exclusion method. Publication bias was assessed using the Begg and Egger tests.

MAIN OUTCOME MEASURES:

Association of asthma susceptibility with TLR4 gene rs4986790 and rs4986791 polymorphisms.

SAMPLE SIZE:

23 articles included 22 studies on the rs4986790 polymorphism and 11 studies on the rs4986791 polymorphism on the TLR4 gene.

RESULTS:

Out of 692 studies screened, 23 met the inclusion criteria. While the overall meta-analysis showed no significant association between the TLR4 rs4986790 polymorphism and asthma susceptibility, subgroup analysis revealed a significant link in the Caucasian population. A significant association was noted in the meta-analysis, particularly among Asian populations, on the rs4986791 polymorphism. The sensitivity analysis indicated that the meta-analysis results were relatively stable. Publication bias analysis revealed minimal influence from publication bias. However, TSA was underscored by the necessity for additional original studies to further validate specific outcomes.

CONCLUSIONS:

Our study underscores the ethnicity-specific impact on the relationship between TLR4 polymorphisms and asthma susceptibility. While the overall findings for rs4986790 were not significant, the association with the Caucasian population merits further investigation. Furthermore, rs4986791 demonstrated a significant correlation with asthma susceptibility, specifically among Asian populations.

LIMITATIONS:

Our study predominantly examined the rs4986790 and rs4986791 polymorphisms, overlooking the potential influence of other genetic variants within TLR4.

Exploring the Relationship Between SNAP Spending, Per-Capita Food Expenses, and Poverty Rates in The United States: A State-level Analysis
Authors: Samuel Esther Rukewve , Ajiboye Ayowole Samuel
Published: June 2024

This paper examines the complex interplay between Supplemental Nutrition Assistance Program (SNAP) spending, per-capita food expenses, poverty rates, and participation trends across U.S. states from 2009 to 2022. Utilizing state-level data obtained from the USDA, Economic Research Service; using data from the State food expenditure series, and the Federal Reserve Bank of St. Louis and others, which were analyzed using R programming. We observed a positive linear regression between SNAP spending and per-capita food expenses over the 14 years, suggesting that changes in SNAP funding consistently influence food expenditure patterns. However, outliers such as New Hampshire, Idaho, and Kentucky exhibit notable correlations between SNAP spending and poverty rates. Moreover, analysis of SNAP participation trends reveals a peak in 2013 followed by a decline until 2019, with a subsequent resurgence from 2020 to 2021 and a slight decrease in 2022. Notably, the top 10 U.S. states demonstrate a general upward trend in per-capita SNAP benefits from 2019 to 2022, with Florida being the sole outlier experiencing a decline in 2022. These findings prompt a deeper exploration into the efficacy of the SNAP program in addressing food insecurity and poverty across diverse state contexts, suggesting potential areas for further research and policy intervention.

Part 2 of the article series is devoted to the formation of dependencies between stresses and deformations in a nonlinear-deformable body. The specific potential energy of deformation of isotropic solid as a function of the components of deformations or invariants thereof is considered and dependencies between stresses and deformations in a nonlinear-elastic environment are obtained. The mechanical properties of the material are characterized by the volume expansion coefficient (compression) K, the functional binding of the octahedral tangent voltage τ_0 and the octahedral shift γ_0, and the parameter, which is determined by the difference of Lode-Nadai coefficients for strain μ_εand stress μ_σ. The relationships between stresses and strains in a nonlinear-elastic body are represented by trigonometric expressions. For the case of simple loading, physical ratios in increments are obtained, which can be directly applied to the implementation of the step algorithm in the finite element method. The obtained dependencies between stresses and deformations are generally used in the Part 3 of the article series to determine the functions used in the formation of analytical expressions for plasticity parameters  and.

This article focuses on the mathematical modeling of the chemical kinetics processes in the interaction of seawater containing chloride, an aggressive environment, with reinforced concrete structures equipped with steel reinforcement. The objective is to refine the mathematical models of the corrosion processes of steel reinforcement in reinforced concrete structures using the fundamental equations of the chemical kinetics of steel oxidation. The study presents a comparative analysis of known mathematical models, indicating that most of them are formal models obtained through the approximation of experimental data. As known, the use of formal mathematical models in scientific research is limited, as these models cannot adequately describe the dynamics of processes in other modes. The evaluation of known models was carried out through the analysis of the structure of mathematical models, the presence of zero initial conditions of differential equations, and the comparison of model structures with chemical kinetics equations. Within the study, a new mathematical model of the dynamics of the corrosion depth change of steel reinforcement under the influence of seawater with an aggressive environment has been developed. This model is presented in the form of a nonlinear differential equation with ordinary derivatives. The scientific contribution also includes analytical solutions for the nonlinear differential equation with ordinary derivatives, considered for two corrosion components instead of four, under the influence of seawater with an aggressive environment.

The paper deals with the formation of the structure of slag-alkali arbolite during curing and the deformation properties of the mortar part, contact zone and organic aggregate. The compression stress of slag-alkali arbolitewas carried out (0.9-1.0) Rpr from the prism strength. It was found that the dependence of the strength of slag-alkali concrete on the initial strength of the solution consists of two sections, which characterize the performance of slag-alkali arbolite concrete in the first and second phases. The obtained results can be used in the manufacture of effective wall material for civil buildings, including for seismic areas.

MATHEMATICAL MODEL OF THE FOUNDATION
FROM ORTHOTROPIC LAYERS CONSIDERING THEIR DEFORMA-TIONAL PSEUDONHOMOGENEITY

Published: June 2024

The article considers the problem of finding the parameters of the stress-strain state (SSS) of a half-space consisting of several layers of various orthotropic materials, whose physical and mechanical characteristics exhibit a significant dependence on the magnitude of stresses, under the influence of uniformly distributed pressure on a rectangular area of a rigid stamp. To build a computational model, a finite element (FE) model was used, based on a modification of an isoparametric FE in the form of a tetrahedron, without intermediate nodes with three nodal degrees of freedom. To describe the process of nonlinear deformation of a half-space, new effective constitutive relations are used that describe the mechanical behavior of orthotropic materials, constructed within the framework of the theory of normalized stress spaces. The calculated parameters of the stress-strain state were compared with the results obtained on the basis of theories proposed by other well-known authors, as well as on the basis of the classical theory, without taking into account the effects associated with resistance differences. The result of the analysis of the data obtained by the authors is a comparison of the theories used, and a conclusion is drawn about the need to consider the non-classical properties of materials.

The Influence of Government and Faith-Based Interventions on the Management of Teenage Pregnancy in Mombasa County, Kenya
Authors: Theuri Joseph
Published: June 2024

The purpose of this study was to assess government and faith-based interventions measures on the management of teenage pregnancy with reference to Mombasa County, Kenya. The findings show that the issue of teen pregnancy is of great concern in the county of Mombasa.  This is evidenced by the high rate of school dropout among girls who got pregnant, early motherhood, transmission of venereal diseases, cases of abortion and death after abortion in some cases. Pearson correlation shows that family stability (0.006, P>0.05) and school based interventions (r=0.063, p>.05) did not have significant effects on the management of teenage pregnancy. On the other hand, the regression coefficients shows that religious interventions could statistically predict the management of teenage pregnancy (P values <0.05). Furthermore, government interventions had a statistically significant moderating influence on the relationship between ecological transformative social change strategies and the management of teenage pregnancy. As a result, the government interventions are urgently needed to address teenage pregnancy in Mombasa County. There is need to put measures in place aimed at checking teenage pregnancies and their associated consequences such as abortions, girls dropping out of school as well as early marriages among others. There is also need to strengthen the contribution of families and school interventions in curbing teenage pregnancy. Civil society organizations, role models and other targeted community based interventions should be carried out to advocate for changes that could lead to reduction in teenage pregnancy among girls. The government in its capacity should be at the centre of ecological transformative social change strategies and the management of teenage pregnancy in Mombasa County.
