Published: June 2023

In the education domain, predicting the academic performance of students has become an essential task to improve learning outcomes. In this study, we propose a Modified XGBoost (MXGB) model for predicting student performance using stream-based analysis of the dataset. We used a modified version of the XGBoost algorithm using cross-validation, which incorporates stream-based analysis to enhance its performance on real-time data. We preprocessed the dataset and applied feature engineering techniques to extract relevant features for building the model. We trained the MXGB model on the preprocessed dataset and evaluated its performance using various metrics such as accuracy, precision, sensitivity, and F1-score. The results show that our model outperforms the baseline XGBoost model and achieves high accuracy in predicting the student's academic performance. Our model can assist educational institutions in identifying students who are at risk of performing poorly and providing them with timely intervention to improve their academic outcomes.

Cosmology is the study of the universe comprising stars and galaxies. Advancement in the telescope has made it possible to capture high-resolution images, which can be analyzed using machine learning (ML) algorithms. This paper classifies the star galaxy dataset into two classes: star and galaxy using ML algorithms and compares their classification performance. It is observed that random forest provides better accuracy of 78% as compared to other ML classifiers. Further to improve the classification accuracy, we proposed a CNN (Convolution Neural Network) model and achieved an accuracy of 92.44%. Since the CNN model itself extracts the characteristics, it exhibits superior classification accuracy.

Published: June 2023

The paper presents the results of a study examining the stability of the grouping of Polish powiats (communes) in Zachodniopomorskie Voivodship in relation to the economic situation in the years 2007–2021. The aim of the research was to determine whether the COVID-19 pandemic affected the economic situation of the powiats. The data used for the calculations were provided by the Local Data Bank of Statistics Poland. On the basis of selected variables characterising the situation of enterprises and the labour market, as well as the financial condition of powiats, the values of the synthetic measure were determined for each powiat in the particular years. Subsequently, the powiats were grouped according to the three averages method (separately for each year). Based on selected similarity measures, the stability of the grouping of powiats was assessed year-to-year in the analysed period. The research demonstrated that the grouping was very stable, which means that in general the pandemic did not affect the economic situation of the powiats.

Published: June 2023

Sentiment analysis of text documents is a very important part of contemporary text mining. The purpose of this article is to present a new technique of text sentiment analysis which can be used with any type of a document-sentiment-classification method. The proposed technique involves feature selection independently of a classifier, which reduces the size of the feature space. Its advantages include intuitiveness and computational noncomplexity. The most important element of the proposed technique is a novel algorithm for the determination of the number of features to be selected sufficient for the effective classification. The algorithm is based on the analysis of the correlation between single features and document labels. A statistical approach, featuring a naive Bayes classifier and logistic regression, was employed to verify the usefulness of the proposed technique. They were applied to three document sets composed of 1,169 opinions of bank clients, obtained in 2020 from a Poland-based bank. The documents were written in Polish. The research demonstrated that reducing the number of terms over 10-fold by means of the proposed algorithm in most cases improves the effectiveness of classification.
Les impacts environnementaux des éruptions volcaniques dans une zone à faible taux d‘exploitation technologique : cas de la province du Nord-Kivu en RD Congo
Authors:   Centre de Recherche en Géophysique (CRG), Kinshasa, République démocratique du Congo, Zana Lambadi Aimé
Published: June 2023

Le volcanisme est l’un des phénomènes naturels terrestres dont l’impact dans l’environnement est très remarquable. Rappelons que le volcanisme de la zone du Virunga, dans la province du Nord-Kivu en RD Congo trouve son origine dans le mécanisme de formation des crêtes médio-océaniques serpentant au milieu des océans Atlantique et Indien avec une extension dans la partie orientale du continent africain. Par ailleurs, le volcanisme du Virunga est particulier en ce qui concerne sa concentration de grands édifices volcaniques sur une zone assez réduite, de fréquences élevées des épisodes éruptives et activités quasi-permanente dans les lacs de laves. La particularité du volcanisme du Virunga génère, plus que pour les autres volcans, une gamme plus diversifiée d’impacts environnementaux. La mise en évidence de ces impacts nous a conduit à formuler quelques mesures en amont de ces éruptions dans le but d’en atténuer les conséquences afin d’amener les populations locales à s’adapter à vivre avec les volcans. Mots clés: Impacts environnementaux, volcanisme, volcan, Virunga, Nord Kivu.

Authors: Ngwu Amauche Martina
Published: June 2023

Malaria is the major cause of morbidity and mortality in the developing countries in which Nigeria is one of them. Malaria during pregnancy is a major cause of maternal death globally. Microscopic analysis of Giemsa stained blood film is still the most suitable method of malaria diagnosis in most developing countries. The aim of this study was to determine malaria parasites number per 100 thick film fields in a Giemsa stained blood film. This is a cross sectional study involving 90 pregnant women within the ages of 19-45 years. Thick and thin smears were prepared on clean glass slide using venous blood. The thick blood smears were stained with 3% Giemsa working solution diluted in pH 7.2 phosphate buffer and examined for the presence of malaria parasites at 100 X oil immersion objective searching 100 fields in each thick smear. Blood smears were examined in the parasitology laboratory of Enugu State University of Science and Technology Teaching Hospital by an experienced microscopist. The level of parasitaemia was indicated in each positive case. The number of parasites in thick blood film was graded using the plus sign: + (1 to 10 parasites per 100 thick film fields); ++ (11 to 100 parasites per 100 thick film fields); +++ (1 to 10 parasites per one thick film field); ++++ (>10 parasites per one thick film field). Bar charts and pie charts were used in this study. Out of 90 pregnant women, 65 (72.2%) of the women had malaria parasite (MP). Out of the 65 pregnant women with MP 19 (21.1%) had one plus (1 to 10 parasites per 100 thick film fields) while 46 (51.1%) had two pluses (11 to 100 parasites per 100 thick film fields). Then 31 (67.4%) of those with two pluses were at age range of 26- 35 years, also 12 (26.1%) of them with two pluses were women that are less than 25 years. However, 25 (27.8%) had no malaria parasite (MP). The findings showed that higher number of the pregnant women had malaria parasites and higher number of individuals positive with malaria parasites had 11 to 100 parasites per 100 thick film fields. Also higher number of pregnant women that had 11 to 100 parasites per 100 thick film fields was at age range of 26- 35 years.

Published: June 2023

This study examined the effects of covid-19 on rice price in northern agricultural zone of Bauchi State, Nigeria. A multi-stage random sampling technique was used in selecting 180 respondents from the study area. Data were collected through the use of structured questionnaire. The result of the study shows that majority (87.8% and 84.4%) were male and married, with about 56.1% of them having tertiary education. The result also revealed the mean age, mean household size and mean household head income as 46 years, 8 people per household and ₦150,000 respectively. The market price trend of rice in the study area shows that rice was sold in August at an average cost of ₦1,320/tiya in urban area, while in the rural area it was sold at an average cost of ₦1,310/tiya within the same period. The result of the regression analysis is revealed that, age of the household head and income were significant (P≤0.05) factors influencing food security in the study area. The study however, discovered that the major constraints faced by the respondents during the pandemic were high price of rice (38.3%), lack of credit (35.0%), lockdown (34.4%), high price of input (32.2%) and lack of alternative employment (29.4%) respectively. The study concluded that the spread of the Covid-19 pandemic had ensued several negative effects such as high price of rice and causes many people to lost their means of livelihood which had directly and indirectly threatened food security in the study area. The study therefore, recommended that, farmers should be encourage to go into more production of rice so that there should be more supply of the commodity to the market. Government should also provide more palliative to household to cushion the effect of the pandemic. There is also the need by Government/NGOs/ Stakeholders to create more employment opportunities in the study area.

Published: June 2023

This study examined the poverty status of farming households in Central Zone of Plateau State, Nigeria. A multi-stage sampling procedure was used in selecting the respondents. Data were collected through the use of structured questionnaire and were analysed using both descriptive (percentage and mean) and inferential statistics (Foster, Greer and Thorbecke and Logistic regression). The results revealed that the mean age of the respondents was 40 years, most of the respondents were married with an average number of 5 persons per households, and relatively low-income level but well educated, it was also confirmed that the average annual income of the respondents was ₦148,855 generated as a result of relatively large farm sizes as indicated by the average farm size of 3.8ha. The finding further reveals that inadequate government support, non-accessibility to improved seeds alongside poor road network/reserves and inadequate healthcare facilities were the major causes of poverty among the respondents. The poverty status was found to be at a moderate poverty line with (2/3 MPCI) of ₦99,236.36 and a core poverty line (1/3 MPCI) of ₦49,618.18, while the poverty incidence and severity were found to be at 0.505 and 0.299 respectively. Some of the major constraints identified in the study area were; inadequate access to funds, security issues and inadequate seminars/workshops. Emanating from the findings it can be concluded that the factors influencing poverty statutes of the farming households were income, education level, age, household size and farming experience. Based on the constraints highlighted the study recommends, the need for government and other relevant stakeholders such as financial agencies and non-governmental organizations to provide support through provision of loans, grants, trainings and seminars on the use of novel technologies in agriculture to foster and boost production among the farming households most especially in the rural settlements.

Published: June 2023

As half the population of the world is constituted by women, their role in economic development is something inevitable. Though they have marked their progress and valuable contributions in all walks of life, their presence in stock market is very much limited. Past researches show that there is a wide gender gap in share trading especially in a developing nation like India. The root cause is that, women undoubtedly face various constraints related to share trading. Therefore, it is imperative to study the influence of these constraints faced by women in share trading, on the resultant outcomes and find possible solutions to it, to improve women participation in this arena. The major intention of the present study is to identify the extent of influence the constraints are causing on the outcomes or the results, and to identify whether there is any difference in its impact on women investors from professional and non-professional working backgrounds in share trading using multi-layer analysis. Primary data was collected using a structured questionnaire which was distributed among women investors in the district of Ernakulam, who are having professional work background as well as non- professional work background. The study concludes on the note that the constraints influence the outcomes or results significantly, and the most affected are the women investors with non-professional work background. The study offers possible solutions to overcome the issues.
A Study on the Working of Rashtriya Swasthya Bima Yojana (RSBY)
Authors: G Vinod , T Biju
Published: June 2023

Risk and uncertainty are incidental to life. These risk and uncertainties are increasing day by day due to increase in fastness in life. To provide against risk and insecurity of human life, insurance came into being. The main underlying principle of insurance is the pooling of risks. Health insurance is bought to cover medical costs for expensive treatments. It is a running fact that the premium on health insurance schemes is too expensive and unaffordable to an average human being. In this regard government responsibility to ensure the health security and health insurance to the financially unsecured becomes a crying need of the hour. To address the mentioned issue, Rashtriya Swasthya Bima Yojana (RSBY), a health insurance scheme for Below Poverty Line (BPL) families has been launched by the Ministry of Labour and Employment, Government of India. Literature shows that the benefit of the scheme is largely confined to rural India than urban. Further it raises the need to reach out to the poorest and the most vulnerable sections of the society, and make available affordable health care to them. Studies further reveals the fact that almost 50 percent of BPL households were found to be poor and only 30 percent of them were aware of RSBY. Lower awareness level and poor penetration are found to be the major hurdles. The beneficiaries of the scheme experience delays of several months to avail the smart cards; poor knowledge of how and where to utilize the scheme; hospitals not trained to use card-reading technology; and month-long delays and arbitrary caps in the reimbursement of treatment expenses to hospitals. Being this as the fact it would be meaningful to see the awareness of people of Kerala about the scheme, the rate of enrollment, the difficulties in enrollment and their real experience as the beneficiaries of the scheme

Published: June 2023

Security comes from the Latin word secure, significantly different from the dangers, fears, and threats associated with traditional and non-traditional security methods. Meanwhile, defense is defined as the most vital technology for the state in carrying out its national security function. National security is defined as the dynamic state of a country which covers all aspects of the nation's life in facing threats. National security includes protection for the state, society, and individuals. Until now, experts have provided several different definitions of the terms security and defense. This article analyzes the current digital information security threats in national security strategies and the implementation of adequate legal protections. This article applies a descriptive qualitative research approach by conducting document analysis. This article describes various information security threats in Indonesia, including disinformation, privilege escalation, and protection against phishing threats, data forgery, and card crime. The similarities and differences between the concepts of defense and security can be observed through regulations, the terminology used, institutions, and constitutions. This article shows that national information security is closely related to policy and closely relates to security, especially ITE policies. It cannot be separated that the security situation of a country depends on security and defense but synergistically with other factors, namely economic, political, legal, socio-cultural, ideological, geographical, and demographic.

Therefore, the constraints in one Content of the Merdeka Belajar Policy, namely the implementation of the Kurikulum Merdeka P5 which is at this early stage, may be used as evaluation material, so that a strategic solution plan can be prepared.
Long-Term Tillage and Crop Sequence Effects on Maize and Soybean Grain Yield Under Eastern Romanian Danube Plain Climate Conditions
Authors: Cociu Alexandru I.
Published: June 2023

Much research around the world has compared the performance of maize (M) and soybean (S) grown under conventional and no tillage systems; however relatively few long-term experiments have been conducted in Eastern Romanian Danube Plain area. In 2012, an experiment was established at Fundulea – Romania, on cambic chernozem soil, testing two tillage treatments [no-tillage (NT) and chisel tillage (CT)], and two crop sequences [soybean (S) and winter wheat (WW) for maize and maize (M) and winter wheat (WW) for soybean]. When compared the two tillage systems, in most experimental years (2012-2017), M as well as S yields were statistically similar. Significant yield increases were determined by higher water amounts of rainfall during vegetation period (from April until August). The smallest yield increase of tillage treatments in NT indicates that CT can be superior to NT as response at higher water amounts of rainfall. WW, as previous crop, had a positive, significant influence on M and S yields. Considering the continuous increasing cost of labor, field equipment and fuel, cultivation of spring crops, as M and S, is preferable within NT system. Additionally, the farmers who adopt the NT practice for spring crops (M and S) can benefit by the economical credit given for preserving the top soil, and possible by the advantages of WW crop rotation.

The anthropogenic warming of the Earth’s atmosphere is causing dynamical and thermodynamical changes in the ocean and atmosphere circulation, including the Asian summer monsoon (ASM) and the oxygen isotope compositions of its precipitation. Here we present a high-resolution speleothem δ18O record from the Shandong Peninsula, eastern China with an age precision of ± 3 years, which in conjunction with five other existing high-resolution speleothem records from the ASM domain, reveals a robust weakening trend in the ASM during the global warming period, particularly since around the 1970s. During this period, both the decline of the Atlantic Meridional Overturning Circulation inferred from existing model-empirical records and the spatially heterogeneous pattern of global warming inferred from the coupled reanalysis of the 20th century (CERA-20C) product result in broadly similar changes in moisture flux pattern in the ASM domain. This, in turn, leads to the ASM weakening trend in terms of dynamics, as suggested by the speleothem δ18O records.

Topological phases of matter are an active research topic because of their multiple applications, including in quantum computers and energy-efficient devices. The last decade has witnessed a growing interest in experimental chemistry-heterogeneous catalysis, asymmetry synthesis, etc. but there remains a lack of understanding of how topological properties interact with the reaction processes. Thus, a critical review of the chemical properties of topological materials is urgent, which is not only important for the design of highly efficient catalysts for clean energy production and carbon neutrality, but also provides an alternative tool to understand and tailor the topological properties for physicists, chemists, and material scientists. In this review, we begin with the concept of topology and topological materials and then attempt to uncover the underlying relationship between topological properties and catalytic reactions. Further, recent progress in the development of topological catalysts for various reactions is discussed, including hydrogen evolution, CO2 reduction, and selective hydrogenation. We discussed the factors that may suppress the contribution of topological electronic structures, especially surface reconstruction, and oxidation. Most importantly, we elaborate on the challenges and controversies in the understanding of the topological catalysis mechanisms from in-situ electrochemical characterization techniques. In the end, we highlight the promising techniques to further uncover the topological catalysis mechanisms and how to extend the application of topological materials.

Hepatitis B virus (HBV) is a major risk factor for hepatocellular carcinoma (HCC), characterized by genomic instability and chronic DNA replication stress. This study presents a robust machine-learning framework using random survival forest to develop a DNA replication stress-related prognostic index (PIRS) for HBV-associated HCC. Transcriptomic expression profiles from 606 HCC cases were used to construct PIRS, which outperformed population-based predictors, demonstrating superior prognostic prediction in HBV-associated HCC. Lower PIRS scores were associated with higher expression of HBV oncoproteins, activated immune/metabolism pathways, and increased responsiveness to immunotherapy. Conversely, higher PIRS scores correlated with elevated Ki-67 marker, cancer stemness, and enrichment in DNA replication stress, cell cycle pathways, and chromatin remodelers, resulting in an 'immune-cold' phenotype and unfavorable clinical outcomes. Through large-scale in-silico drug screening, potential therapeutic targets (TOP2A, PRMT1, CSNK1D, and PPIH) and five agents, including topoisomerase and CDK inhibitors, were identified for patients with high PIRS scores. These findings hold promise for optimizing therapeutic strategies in HCC and providing insights into the management of HBV carriers. In summary, our machine-learning approach yielded PIRS as a powerful predictor for assessing prognosis in HBV-associated HCC. This analytic framework improves population-based therapeutic strategies, facilitates personalized treatment, and ushers in a new era of precision medicine in HCC.
