The application of machine learning (ML) tools and data-driven modeling became a standard approach for solving many problems in exploration geology and contributed to the discovery of new reservoirs. This study explores an application of machine learning ensemble methods – random forest (RF) and extreme gradient boosting (XGBoost) to derive porosity and saturation type (gas/water) in multi-horizon sandstone formations from Miocene deposits of the Carpathian Foredeep. The training of ML algorithms was divided into two stages. First, the RF algorithm was used to compute porosity based on seismic attributes and well location coordinates. The obtained results were used as an extra feature to saturation type modeling using the XGBoost algorithm. The XGBoost was run with and without well location coordinates to evaluate the influence of the spatial information for the modeling performance. The hyperparameters for each model were tuned using the Bayesian optimization algorithm. To check the training models' robustness, 10-fold cross-validation was performed. The results were evaluated using standard metrics, for regression and classification, on training and testing sets. The residual mean standard error (RMSE) for porosity prediction with RF for training and testing was close to 0.053, providing no evidence of overfitting. Feature importance analysis revealed that the most influential variables for porosity prediction were spatial coordinates and seismic attributes sweetness. The results of XGBoost modeling (variant 1) demonstrated that the algorithm could accurately predict saturation type despite the class imbalance issue. The sensitivity for XGBoost on training and testing data was high and equaled 0.862 and 0.920, respectively. The XGBoost model relied on computed porosity and spatial coordinates. The obtained sensitivity results for both training and testing sets dropped significantly by about 10% when well location coordinates were removed (variant 2). In this case, the three most influential features were computed porosity, seismic amplitude contrast, and iso-frequency component (15 Hz) attribute. The obtained results were imported to Petrel software to present the spatial distribution of porosity and saturation type. The latter parameter was given with probability distribution, which allows for identifying potential target zones enriched in gas.

Information needs of prospective postgraduate students
Authors: Konyana Samkele 
Published: March 2022

The complex application process at the postgraduate level became a major blamer for poor doctorate enrolments. The complexity in the communication messages made it difficult for prospective postgraduate students to absorb information effectively. The proposal by the government to increase masters' and doctorate enrolments at universities requires universities to cater to the needs of customers whose preferences and expectations change continuously. The research upon which this paper was based was aimed at identifying the information needs of prospective postgraduates at public universities. The study design is quantitative, employing a descriptive technique and cross-sectional method. For the empirical study, a non-probability sampling method was utilized to obtain data from a sample of 116 masters’ and doctorate students. Descriptive statistics described the main features of the collected data through frequencies, tables, and bar charts. Inferential statistics were used to determine relationships between variables and test the significance, and reliability of the findings. Emphasis on university processes and specific aspects of the expected and augmented product were found. Interestingly, the importance attached to getting information about economic incentives significantly outweighs the importance attached to receiving information about the actual product. The results of this study affirm the assertion that the postgraduate market is unique and has unique information needs. The results provide universities with a guideline to identify the information needs of prospective postgraduate students applying for master's and doctorate studies at public universities. The study limitation is that it encompasses only a small number of registered master’s and doctoral students in KwaZulu-Natal, limiting the possibility of generalizing the results to all prospective postgraduate students in South Africa.

The purpose of the study was to evaluate the challenges encountered by the South African Police services (SAPS) when dealing with 4IR. The study used a qualitative approach because the study wished to obtain practical answers to the problem, as well as the explanations provided by participants who are practitioners in the field and a total of forty (40) police officers were selected to participate in the study. The researcher followed purposive sampling. The reasoning for using purposive sampling is that it is based on the assumptions that the participants have in-depth knowledge in the chosen areas of the study. The findings of the study are that the local police stations of SAPS Gauteng are where many victims of crimes emerging from 4IR get turned away by officials who do not understand the various cybercrimes, the applicable charges, or how to go about escalating the matter. The study further found that the Government policy seems to prioritize statistics, quotas, and the images they reflect as opposed to the true situation hence crimes emerging from 4IR are poorly understood, prevented, and investigated. The study recommends that IT capacity and resources within SAPS have to be developed in order to ensure that the SAPS in Gauteng province is able to investigate, combat and trace the sophisticated crimes caused by the criminals. The SAPS needs to allocate funds to buy IT equipment, software and headhunt personnel who have skills, knowledge, and capacity to curb, investigate and combat 4IR crimes.

Entrepreneurs play pivotal roles that affect the economy. These roles are job creation, wealth generation, economic growth, and innovation. According to WorldBank data, they account for around 90% of enterprises and more than half of all jobs in the globe. In emerging economies, formal SMEs account for up to 40% of national income (GDP). The prolonged effects of the COVID-19 pandemic which resulted in job losses have encouraged even the Filipino Generation Z to engage in entrepreneurial activities. This supports various studies conducted by research firms recently that 54% of Generation Z wanted to start their own business venture. Thus, this research aims to determine the influence of entrepreneurial attitude, social valuation, entrepreneurial skills, and entrepreneurial knowledge on entrepreneurial intention. There were 110 Generation Z respondents who answered the adopted survey questionnaire. The researchers were able to secure permission from the original author to use the research instrument. The research utilized a quantitative research design primarily descriptive-correlational. The data were processed using regression analysis to test the relationship of variables. The regression results preceded the acceptance of the 4 hypotheses which means that entrepreneurial attitude, social valuation, entrepreneurial skills, and entrepreneurial knowledge significantly influence entrepreneurial intention. The results will be considerably useful to academics to promote entrepreneurship from high school to college level, to future entrepreneurs in identifying the factors that influence entrepreneurial intention, to the government and its regulators for policy development, and to researchers who plan to expand the literature on the entrepreneurial mind.

Published: March 2022

En una sociedad globalizada se hace necesario abrir las instituciones educativas al entorno y fomentar la participación ciudadana de los jóvenes en el desarrollo sostenible. Una forma de implicar a los jóvenes en el desarrollo sostenible es a partir de las salidas de campo que les permiten estar en contacto con su entorno; para ello se hace necesario plantearse metodologías de enseñanza y aprendizaje que permitan implicar a nuestro alumnado y a su vez facilitarles un papel activo en la sociedad. Con el auge de las tecnologías digitales, el futuro de la educación ha de conseguir implicar a los jóvenes en los municipios y darles voz para hacerles partícipes en el mundo que les rodea. En este artículo presentamos una propuesta didáctica basada en el storytelling digital usando el vídeo para implicar a los niños y jóvenes en el desarrollo sostenible durante las salidas de campo. La propuesta se ha experimentado en un instituto de la provincia de Girona y se aborda desde un enfoque de investigación cualitativa. El análisis de los resultados obtenidos a partir de la experimentación de la propuesta didáctica nos muestra el potencial del storytelling digital para sensibilizar e implicar a los jóvenes en el desarrollo sostenible.

La memoria estética del videojuego
Authors: Venegas Ramos Alberto , Gutiérrez Manjón Sergio 
Published: March 2022

El videojuego como artefacto cultural traspasa su concepción lúdica construyendo sus propias funciones de socialización y representación como el resto de los medios de comunicación. Entre estas funciones se desarrolla la puesta en escena de una determinada memoria estética que alude a referentes intertextuales compartidos en otros medios. A través del análisis de contenido de Blasphemous, videojuego creado por el estudio sevillano The Game Kitchen, podemos analizar las fuentes de dicha memoria con el objetivo de examinar cómo se reproducen las tradiciones y ritos de Andalucía en el universo mediático y globalizado del videojuego. Así pues, Blasphemous, como dispositivo cultural, adopta una serie de señas identitarias que representan dentro de su iconografía la ciudad de Sevilla, la religiosidad cristiana barroca y la cultura andaluza. De esta forma, Blasphemous adapta estas referencias a una propuesta artística basada en los nuevos medios digitales y virtuales en clave de videojuego cuyo fin es la diversión, la seducción y la rentabilidad al ser un producto de masas dotándolo de nuevos significados.

Published: March 2022

Abstract
In recent years, many scientific studies have analyzed potential solutions and opportunities to improve food systems towards sustainability. Various socioeconomic factors play crucial roles in determining the successful or unsuccessful implementation. Yet, systematic reviews, which provide a comprehensive picture of food systems-socioeconomic relationships, are still lacking. Such studies could integrate crucial information, particularly important for stakeholders who rely on scientific articles when making decisions. Therefore, we aim to systematically screen and review existing literature to draw common patterns of feasible socioeconomic measures essential for sustainable food systems. The objective of this protocol is to outline the methods we use and to avoid bias, especially when screening relevant articles.

Abstract
Background: Similar to other African countries, life expectancy of people living with HIV infection has improved due to access to antiretroviral therapy (ART) in Rwanda. However, both HIV infection and use of ART are associated with cardiovascular disease (CVD) risks, due to adverse changes in some biochemical markers, causing dyslipidemia and other metabolic imbalances. Biomarkers for CVD risk in HIV-infected individuals taking ART, has not been well characterized in Rwanda. We evaluated the association between the use and duration of ART and biomarkers of CVD risk among HIV infected adults in Rwanda. Methods: A total of 150 participants (18-45 years) from HIV clinics in public Health Center in Kigali included n=30 HIV-uninfected (HIV-) and n=120 HIV-infected (HIV+) adults. Among the HIV+ adults, n=40 participants were ART-naïve. Cross-sectional data were collected on health-related behaviors and biochemical markers of CVD risk. We compared CVD-related biochemical markers between HIV-, HIV+ ART-naïve and HIV+ on ART groups. Results: The majority of participants were women (60%) and HIV- were younger (35±6 vs. 31±6 years). Total cholesterol and triglycerides concentrations were associated with ART usage. Serum triglycerides concentrations were lower in HIV+ ART-naïve compared to HIV+ on ART (76.6±38.9 mg/dl vs. 85.0±38.3 mg/dl; p< 0.01). While total cholesterol concentrations was higher in HIV+ on ART than HIV+ ART-naïve (136.0±45.1 mg/dl vs. 130.0±36.5 mg/dl; p<0.04), HDL-C was higher in those taking ART (68.7±30.0 mg/dl vs. 55.0±25.7 mg/dl; p=0.02) among HIV+ on ART for 0-6 months and 7-12 months respectively. Conclusion: Higher serum total cholesterol and triglycerides were associated with use of ART in young adults with HIV. Although these values were within the upper limits of normal, our findings suggest early alterations in biomarkers of cardiac risk. These findings underscore the need for early evaluation of lipid profiles as biomarkers of cardiovascular disease risk, to effectively monitor how ART may contribute to cardiovascular disease and deter treatment programs in African countries.

Abstract
Background
Paralytic ileus is common in patients with septic shock, which causes high morbidity and mortality. Enteric neurons and enteric glial cells (EGCs) regulate intestinal motility, but little is known about their interaction in endotoxemia. We aim to investigate whether reactive EGCs have harmful effects on enteric neurons and participate in intestinal motility disorder in mice during endotoxemia.
Methods
Endotoxemia was induced by lipopolysaccharide (LPS) intraperitoneal injection in mice. And fluorocitrate (FC) was administered before LPS injections to inhibit the reactive EGCs. The effects of reactive EGCs on intestinal motility were analyzed by motility assays in vivo and colonic migrating motor complexes (CMMCs) ex vivo. The number of enteric neurons was evaluated by immunofluorescent staining HuCD, nNOS and ChAT in vivo. In addition, we stimulated EGCs with IL-1β and TNF-α in vitro and cultured the primary enteric neurons in the conditioned medium, detecting the apoptosis and morphology of neurons through staining TUNEL, cleaved Caspase-3 protein and Anti-β-III tubulin.
Results
Intestinal motility and peristaltic reflex can be improved by the inhibition of reactive EGCs in vivo. There is an increased density of the neuronal population in the colonic myenteric plexus significantly while the reactive EGCs are inhibited, especially the nitrergic neurons. In vitro, the enteric neurons cultured in the conditioned medium of reactive EGCs had significantly more apoptotic rate and less dendritic complexity and number of primary neurites.
Conclusion
Reactive enteric glial cells participated in paralytic ileus by damaging nitrergic neurons during endotoxemia. It could provide a novel therapeutic strategy for intestinal motility disorders during endotoxemia or sepsis.

Published: March 2022

Abstract
Background:Cervical spondylotic myelopathy patients with multiple segments are usually treated with surgery via the posterior approach, but expansive open laminoplasty (ELAP) often results in heavy, rigid, and acid bilge feelings in the neck, shoulder, and back, collectively known as axial symptoms. Objective: To evaluate the effect of modified posterior cervical ligament complex reconstruction and single-door laminoplasty with titanium plate fixation on postoperative axial symptoms in patients. Methods: We conducted a retrospective study including 132 cases of cervical spondylotic myelopathy at our institute from June 2016 to March 2018. Gender, age, operation time, intraoperative blood loss, post-operative drainage volume, and follow-up time, Visual analogue scoring (VAS), cervical curvature index (CCI) and the cross-sectional area of the posterior cervical muscles of the two groups were recorded. Results: There was statistical significance in the incidence of axial pain 3 months after surgery (P = 0.001), 6 months after surgery (P = 0.006), and 1 year after surgery (P = 0.015). Compared to group b, the VAS score in group A was decreased 1 week (P <0.0001), one month, 3 months (P=0.0001), 6 months(P=0.0076), and 1 year(P=0.0085) after surgery. The CCI and the posterior cervical muscle area also differed significantly between the two groups (P < 0.0001).Conclusion: Modified single open-door laminoplasty could relieve cervical axial pain in patients with cervical spondylotic myelopathy.
