ASSESSING THE EFFICIENCY OF CEMENT KILN DUST FOR HEAVY METALS REMOVAL FROM SIMULATED POLLUTED WATER
Authors: Mansoor S. S , Al-Esawi J. Sh. , Al-Falahi M. N.
Published: July 2023

Heavy metal contamination in the environment is unavoidable issue. Heavy metals directly influence human being lives since they concentrate in the food cycle, even in low amounts. Some heavy metals pollute the water resources, in dangerous limits for human life. The current study suggested the cement kiln dust (CKD) as a low-cost and effective adsorbent to remove heavy metals ions from solutions. Therefore, the study investigated the copper, lead and cadmium removal from aqueous solution by cement kiln dust (CKD) as industrial by-product. The laboratory experiment included two factors. The first factor consists of three different diameter particles i.e., 50,100, and 150 . While the second factor included three concentrations of each of copper, cadmium, and lead ions namely 50,100, and 200 mg. l-1. The cement kiln dust was identified by X-ray diffraction analysis (XRD) to determine its chemical characteristics. Also, pH and EC were measured for the cement kiln dust solution. Before the study starting, the initial concentration of the copper, cadmium, and lead were measured in the CKD power. The study was conducted at temperature of 25 . The removal efficiency was calculated at two different time of shaking, namely 1 and 2 hours. The obtained results indicated that CKD can be used as a low cost and effective sorbent for copper, cadmium, and lead ions from polluted water. Moreover, the results show that the high pH and high surface area for the cement kiln dust have the main effect of making the CKD efficient adsorbent material.

Eurointegration and europeanization as innovative goals of political and socio-economic development of the Visegrad Countries: features and stages of implementation
Authors:   Akademia Nauk Stosowanych Gospodarki Krajowej, Białobłocka Sławomira
Published: July 2023

The article is devoted to analyzing the features and stages of the implementation of Eurointegration and Europeanization as innovative goals of political and socio-economic development of the countries of the Visegrad Group. It was argued that Western countries played an important role in reforming and political and socio-economic development of the Visegrad countries. The author proved that the support of the countries of the region in their socio-economic and political modernization and democratic transformations, on the one hand, is the innovative goal of political and socio-economic development of the countries of the Visegrad Group, on the other – the goal of foreign policy of the West. The researcher also singled out the stages of Eurointegration and Europeanization of the Visegrad Group countries. It has been established that the importance of Eurointegration and Europeanization of the Visegrad Group countries during all years of transformation were subordinated to the implementation of the modernization strategy and the fulfillment of formal criteria for the EU membership. As a result, Eurointegration and Europeanization processes have become a kind of “catalyst” and innovative logic not only for political and socio-economic development, but also for the formation of civil society infrastructure.

Authors: Yao Lihua , Jiao Hong
Published: July 2023

This study used Kaggle data, the ASAP data set, and applied NLP and Bidirectional Encoder Representations from Transformers (BERT) for corpus processing and feature extraction, and applied different machine learning models, both traditional machine-learning classifiers and neural-network-based approaches. Supervised learning models were used for the scoring system, where six out of the eight essay prompts were trained separately and concatenated. Compared with previous study, we found that adding more features such as readability scores using Spacy Textsta improved the prediction results for the essay scoring system. The neural network model, trained on all prompt data and utilizing NLP for corpus processing and feature extraction, performed better than other models with an overall test quadratic weighted kappa (QWK) of 0.9724. It achieved the highest QWK score of 0.859 for prompt 1 and an average QWK of 0.771 across all 6 prompts, making it the best-performing machine learning model that was tested.

Changes of the activity of glutamine synthetase in an experimental model of hypoxic preconditioning
Authors: Khairova V.R.
Published: July 2023

In the present work, the effect of hypoxic preconditioning on the activity of glutamine synthetase in the brain structures of old rats subjected to severe hypoxia was studied. The study of metabolic changes, in particular, some enzymes of glutamate metabolism, in the brain under conditions of oxygen deficiency and during hypoxic training is an actual problem, the solution of which makes it possible to determine possible ways to protect the nervous tissue from hypoxic damage and increase its stability. Hypoxia does not always induce cell death; under certain conditions, hypoxic exposure has a neuroprotective effect. Hypoxic preconditioning increases the resistance of neurons to the effects of more severe forms of hypoxia. In particular, the endogenous neuroprotective mechanism is triggered, the activity of glutamine synthetase increases, and, as a consequence, the neurotoxicity of glutamate decreases.

Published: July 2023

Vermicomposting in portable bins is usually adopted nowadays after the public understanding of vermicompost process increased and its deployment to convert organic waste into vermicompost has been increasingly expanded. Using worms, the vermicomposting technique turns food scraps, manure, and other biodegradable waste into "vermicast," which is an excellent fertilizer. Ease of the vermicompost process and ability of its application in various scales made the vermicomposting a popular issue almost everywhere. The experimental descriptive research method was used in this study specifically the true experimental research design that relied on statistical analysis to approve or disprove a hypothesis. The researcher conducted a 15-day experiment to observe and collect data and the process were divided into two stages: development and assessment. A total of 12 portable bins were put up in the experimental study and used them in developing and accessing which organic substrates are highly efficient in producing vermicast. Four sets with triplicate (T) bins containing worms and soil for control, and for the experimental agricultural wastes for T1, food wastes for T2 and office waste for T3. These bins were observed for 15 days and from the data collected, researcher found out that in experimental bins, the replicates with agricultural wastes produced the highest amount of organic fertilizer or the vermicast, followed by the food waste (fruit peelings and vegetable scraps) and the least from office wastes (shredded paper). The findings in this study led to the statement that portable bins made from utility boxes can develop and produce organic fertilizer from Vermicomposting, using agricultural waste materials preferably.

Published: July 2023

The outbreak of the COVID-19 in the Philippines affected the country’s economy and public health of the Filipinos.  As the number of COVID-19 positive increases, government hospitals reached out to private hospitals to form sustainable public-private partnerships to combat the spread of the Virus.  The role of frontliners become significant, hence they exerted more efforts in their work and some of them suffered symptoms of both physical and mental fatigue, depression and anxiety.  This study utilized descriptive research design; snowballing technique was used to identify the 40 frontliner-respondents who met the criteria of the research.  The Depression Anxiety Stress Scale – 21 (DASS-21) developed by Lovibond and Lovibond (1995) was utilized as instrument.  Results revealed that: majority of the frontliners’ stress and depression levels was in the normal to moderate levels; while their level of anxiety was dominant in the severe to extremely severe levels; nonetheless, around 35 percent of the frontliners experienced severe to extremely severe level of depression.  A higher number of frontliners in public hospitals experienced higher levels of stress, anxiety and depression compared to the frontliners in private hospitals.  Significant difference was established between the anxiety levels of frontliners in public and private hospitals; while no significant difference was established between their stress and depression levels.  Findings of the study should be utilized by the hospital administrations to counteract the psychological status of the frontliners, the identified individuals with severe to extremely severe levels of psychological status are the most vulnerable and needs immediate intervention.
Project Monitoring with Decision Support System for the University Infrastructure Development Office
Authors: Dizon Juan Paolo , Sonza Rolaida
Published: July 2023

Project Monitoring is the process of keeping track of all project-related metrics that includes task duration and team performance, identifying potential problems and taking corrective actions necessary to ensure that each project is within the scope, budget, and specified timeframe. The University Infrastructure Development Office still has the traditional way of manually keeping the records of each project such as printed copy. The risk of having a permanent file document that is being produced as hard copy can be vulnerable to fire, flood, insects and so much more where we cannot retrieve those important files in case of those unexpected situations.

This research project employed the Agile Software Development Methodology to develop an Online Project Monitoring System that can be used by the university in the infrastructure development section to give them a much more organized project tracking, reviewing and regulating the progress in order to meet the performance objectives of each project across the university. The system aims to help the institution to digitize the printed records of projects in the university in an organized manner and stored securely in a database system. The researcher adapted the ISO/IEC 25010 criteria as an evaluation tool to assess the system’s functional suitability, performance efficiency, compatibility, usability, reliability, security, maintainability, and portability.

The assessment and evaluation results of the system indicates that the PMDSS passed and conformed with the standard software quality requirements and met all the end-users expectation and objectives that will greatly help them in monitoring of projects and making them more productive. This proves that the system can improve the management of running projects across the university and decision making of the Infrastructure Development Office.

Cet article lance un débat et propose des actions pour notre association. L’association GUTenberg a de nombreuses activités 52, mais malheureusement, le sujet de l’enseignement au collège et au lycée n’a jamais réellement été pris à bras le corps. Développer l’utilisation de nos logiciels préférés dans ce monde-là est délicat. En effet, si dans l’enseignement supérieur et la recherche, LaTeX est assez utilisé, au moins dans le monde des mathématiques voire de la physique théorique où son utilisation est même obligatoire, dans l’enseignement secondaire, LaTeX est malheureusement trop rarement utilisé.

Gobernanza territorial y planificación estratégica participada en el mercado laboral: el Laboratorio Territorial para el Empleo Valenciano
Authors: Hermosilla Pla Jorge , Fansa Saleh Ghaleb , Mayordomo Maya Sandra , Aparicio Vayà Jose Vicente , Fernández Villarejo Mónica
Published: July 2023

Desde 2016 el gobierno autónomo valenciano ha impulsado una iniciativa relacionada con la mejora del mercado laboral, que consiste en el diseño y el desarrollo de un conjunto de acciones recogidas y asentadas en el Laboratorio Territorial del Empleo Valenciano, dependiente del Servicio Valenciano para el Empleo, conocido por Labora-GVA.
El artículo comprende dos apartados diferenciados. El primero recoge los criterios y los principios que permitieron diseñar la estructura del futuro Laboratorio Territorial para el Empleo, y para ello se atendieron algunas claves territoriales, como son la escala territorial local, los fundamentos del desarrollo territorial y las bonanzas de la planificación estratégica, como instrumento para la ordenación y organización de acciones. Adquieren protagonismo tanto los diagnósticos territoriales como las estrategias definidas para la mejora de los mercados laborales locales. Un proceso en el que los pactos territoriales por el empleo son actores fundamentales, dado que se trata de un enfoque tipo ascendente o bottom-up.El segundo de los apartados caracteriza el proceso de puesta en marcha del Laboratorio Territorial del Empleo, que se extiende durante el periodo 2017-2022. Se analizan las acciones que han ido desarrollándose, de las cuales adquieren especial relevancia los proyectos experimentales, impulsados por los propios pactos por el empleo.Finalmente, se realiza un balance del proceso de implantación y desarrollo del Laboratorio Territorial para el Empleo Valenciano.

Herein, we report a case of thromboembolic disease occurring during endemic Kaposi’s disease treated with bleomycin. Kaposi’s disease is a vascular and fibroblastic disorder caused by human herpes virus type 8. The endemic form remains prevalent yet with a less severe prognosis. The first line of systemic treatment in our country is classically a monotherapy with bleomycin. This case of endemic Kaposi’s disease was treated with bleomycin monotherapy that reportedly caused thromboembolic disease on two occasions after administration. This was one of the rarely reported effects of bleomycin in monochemotherapy, especially in the case of the treatment of endemic Kaposi’s disease, considering the chronology of the appearance of this effect in your patient. Key words: Bleomycin; Thromboembolic disease; Endemic Kaposi’s disease
Control of ochre dermatitis with aminaphtone in an adolescent
Authors: de Godoy Lívia Maria Pereira , de Godoy Ana Carolina Pereira , de Godoy Henrique Jose Pereira , de Godoy Jose Maria Pereira
Published: July 2023

The aim of this manuscript is to report the case of a 22-year-old adolescent who presented with brownish patches on the skin of her lower legs persistent since the age of eleven years. She was treated by a dermatologist since the age of twelve years with a clinical diagnosis of ochre dermatitis confirmed by a biopsy. The patient was treated for two years without a success and was sent to a vascular surgeon at fourteen years of age. The diagnosis was confirmed, and the venous duplex scan discarded the possibility of a macrocirculation abnormality. The patient was treated with aminaphtone with the normalization of the skin for two years, after which the patches returned and were controlled again with the same medication. As ochre dermatitis may be associated with capillary fragility, the use of aminaphtone is a therapeutic option. Key words: Ochre Dermatitis; Hyperpigmentation; Capillary Fragility; Aminaphtone; Adolescent
Depredación ocasional de Sus scrofa L. sobre una metapoblación relíctica de Margaritifera margaritifera L. (Bivalvia: Mollusca) en el río Negro (NO de España)
Authors: Morales Javier , Peñín Esther , Lizana Miguel
Published: July 2023

The wild boar (S. scrofa L.) is a generalist feeder that occasionally predates on semi-aquatic and terrestrial molluscs. We document for the first time the massive predation of wild boar on an aquatic epibenthic prey, the endangered freshwater mussel M. margaritifera. During the severe drought of 2009 an important part of the Negro mussel population was found predated by wild boar in a stretch subject to an episodic low level of water. Severe drought and boar predation caused the death of around 40% of the individuals in this metapopulation in the lower reaches of the river, which is the largest population near the southern limit of its global distribution. We propose a survey of the mussel colonies during periods of drought and the translocation of the mussels to deeper areas of the river in order to avoid this endangered mussel being accessible during the summer to the scavenging of wild boar.

Published: July 2023

Background: Vaccination is considered to be the most effective way of preventing influenza related-illnesses and their complications, which is particularly important in elderly population (aged 65+), often characterized with more rapid and severe clinical course of infection. Quadrivalent influenza vaccines (QIV) have been developed to avoid the poor antigenic match observed in the trivalent formulation vaccine (TIV). Methods: The study assess the immunogenicity, cost-effectiveness and impact on the Polish budget of inactivated quadrivalent influenza vaccine (VaxigripTetra), assuming its reimbursement in the active immunization of adults 65 years of age and older. Results: As clinical results have shown, non-inferior immunogenicity of QIV to each TIV for the shared strains and superior immunogenicity of QIV to each TIV for the alternate B strain. The inactivated QIV was well tolerated. VaxigripTetra is a highly cost-effective option compared to the strategy of “no vaccination” (ICUR=14,988 PLN/QALY – payer’s + patients’ perspective [PPP+P], ICUR=6,838 PLN/QALY – payers’ perspective [PPP]) and also to TIV (ICUR=121,418 PLN or ICUR=114,360 PLN, respectively). The increase of the public payer’s expenditures – 9.0-23.3 million PLN annually – will result in additional health effects: 1,091 – 4,805 GP visits, 175-771 hospitalizations and 74-326 deaths avoided per year. Conclusions: VaxigripTetra reimbursement could trigger a faster switch from TIVs to QIVs and at the same time could increase the vaccine coverage of the elderly population in Poland, which would lessen the ILI-related negative impact on that population at a reasonable cost to the healthcare system, while providing some savings to society.

The rationale for the initial project performed in the Central and Eastern European countries (CEE) was to assess and to share information from the region regarding drug policies. With this special cross countries comparison we aimed to analyze the significance of real world data (RWD) and real world evidence (RWE) for access to new therapies decisions and orphan drugs policies. We focused our comparison on the selected CEE countries (Poland, Estonia, Latvia, Croatia, Czech Republic and Hungary). It shows that although all of those countries are using HTA during reimbursement process, the approach towards RWD is different. In most of the cases RWD are not mandatory for reimbursement decisions, however in all the countries RWD can be submitted as supportive information for the decision making process.

An incremental move towards universal health coverage (UHC) is an important issue in many developing countries. There is often limited fiscal capacity for UHC implementation, which results in restricted access to health care and high level out of pocket payments. An important policy question is whether health insurance (HI) provided by non-governmental actors – either on non-profit or for-profit basis – can support UHC implementation to resolve problems? This paper argues that the nature of HI arrangements provided outside the governmental schemes strongly depend on the structure and evolution of the publicly funded system and on the extent to which regulators let non-governmental health care actors support the publicly funded system. Collaboration between public and private stakeholders is important to facilitate the implementation of UHC supported by supplementary and complementary HI schemes.

The term ‘Value Based Healthcare’ was first used in 2001 to describe a situation where payor demands that only services providing the best health outcomes for patients are offered. Since then, it evolved to include safety of services, equity in healthcare access, mutual respect between caregivers and patients and improvement of work life of healthcare professionals. In this article, we present a history of Value-Based Healthcare concepts and highlight the main differences between successive models. Then we proceed to point out the main constraints and problems with the implementation of VBHC. In the end, we evaluate the implementation of this concept in Poland.

Objective: The term “weekend effect” refers to an increase in the mortality rate for hospitalizations occurring on weekends versus weekdays. In this study, we investigated whether such an effect exists in patients undergoing mechanical thrombectomy for acute ischemic stroke with large vessel occlusion (currently the standard treatment for this condition) at a single center in Japan.Methods: We surveyed 151 patients who underwent mechanical thrombectomy for acute ischemic stroke with large vessel occlusion (75 and 76 patients were treated during daytime and nighttime, respectively) from January 2019 to June 2021. The items evaluated in this analysis were the rate of modified Rankin Scale ≤2 or prestroke scale, mortality, and procedural treatment time.Results: The rates of modified Rankin Scale ≤2 or prestroke scale and mortality at 90 days after treatment did not differ significantly between daytime and nighttime (41.3% vs. 29.0%, p=0.11; 14.7% vs. 11.8%, p=0.61, respectively). The door-to-groin time tended to be shorter during daytime versus nighttime (57 [IQR: 42.5–70] min vs. 70 [IQR: 55–82]) min, p=0.0507).Conclusions: This study did not reveal differences in treatment outcome between daytime and nighttime in patients undergoing mechanical thrombectomy for acute ischemic stroke with large vessel occlusion. Therefore, the “weekend effect” was not observed in our institution.

Introduction: Early introduction of fluids and water affects the duration of breastfeeding, the infant immune system, and possibly causes infants to consume less breast milk, which may, in turn, affect their nutritional and immune status.Objective: This study was carried out to determine water consumption in 0-6-month-old infants and the factors affecting this consumption.Materials and methods: A literature review was conducted in seven electronic databases (Medline, Web of Science, PubMed, ScienceDirect, Scopus, Cochrane Library, andTÜBITAK) for studies published until April 25, 2022, using the keywords: drinking water, infant, and breastfeeding.Results: The systematic review included 13 studies. Five studies were crosssectional, three were descriptive and quasi-experimental, and the others were case-control and cohort studies. It was reported in the examined studies that 86.2% of the infants were around 6 weeks old, 44 % of the infants were 1 month old, 77% were 3 months old, 2.5% were 4 months old, and 2.5 to 85% of the infants were around 6 months old when they first consumed water. The prominent reasons for making the infants drink water are the thought that they need it and cultural reasons.Conclusions: The exclusive breastfeeding of 0-6-month-old infants is the recommendation of reliable health authorities. Nurses play a key role in implementing this practice. In this systematic review, it was seen that families gave their infants water at varying rates in the 0-6-month period, and the factors affecting this situation were revealed. If nurses determine which factors affect families in terms of the early introduction of fluids, they could be able to plan the necessary education and interventions.

Published: July 2023

An immense volume of digital documents exists online and offline with content that can offer useful information and insights. Utilizing topic modeling enhances the analysis and understanding of digital documents. Topic modeling discovers latent semantic structures or topics within a set of digital textual documents. The Internet of Things, Blockchain, recommender system, and search engine optimization applications use topic modeling to handle data mining tasks, such as classification and clustering. The usefulness of topic models depends on the quality of resulting term patterns and topics with high quality. Topic coherence is the standard metric to measure the quality of topic models. Previous studies build topic models to generally work on conventional documents, and they are insufficient and underperform when applied to web content data due to differences in the structure of the conventional and HTML documents. Neglecting the unique structure of web content leads to missing otherwise coherent topics and, therefore, low topic quality. This study aims to propose an innovative topic model to learn coherence topics in web content data. We present the HTML Topic Model (HTM), a web content topic model that takes into consideration the HTML tags to understand the structure of web pages. We conducted two series of experiments to demonstrate the limitations of the existing topic models and examine the topic coherence of the HTM against the widely used Latent Dirichlet Allocation (LDA) model and its variants, namely the Correlated Topic Model, the Dirichlet Multinomial Regression, the Hierarchical Dirichlet Process, the Hierarchical Latent Dirichlet Allocation, the pseudo-document based Topic Model, and the Supervised Latent Dirichlet Allocation models. The first experiment demonstrates the limitations of the existing topic models when applied to web content data and, therefore, the essential need for a web content topic model. When applied to web data, the overall performance dropped an average of five times and, in some cases, up to approximately 20 times lower than when applied to conventional data. The second experiment then evaluates the effectiveness of the HTM model in discovering topics and term patterns of web content data. The HTM model achieved an overall 35% improvement in topic coherence compared to the LDA.
Diet and physical activity and metabolic disorders in patients with schizophrenia and bipolar affective disorder in the Polish population

Published: July 2023

Introduction

There are numerous reports of a higher prevalence of metabolic disorders in patients with schizophrenia and bipolar disorder (BD), yet its connections to diet and physical activity remain not fully explained. This article aimed to evaluate diet, physical activity and selected biochemical and anthropometric parameters associated with metabolism in patients with schizophrenia and BD and to analyse the relationships between these variables in the subjects.

Materials and Methods

A total of 126 adults participated in the study: 47 patients with schizophrenia, 54 patients with BD and 25 patients in mental illness remission (reference group). Data were collected on the underlying illness and concomitant illnesses, and the severity of symptoms of the current episode was assessed using the following scales: PANSS, MADRS and YMRS. An assessment of the subjects’ diet (KomPAN questionnaire) and their physical activity (International Physical Activity Questionnaire) was carried out. Anthropometric and blood pressure measurements were taken and BMI and WHR were calculated. Serum concentrations of fasting glucose, TSH, total cholesterol, LDL and HDL fractions, triglycerides and leptin, ghrelin and resistin were determined. For statistical analysis, the significance level was set at 0.05. For multiple comparisons one way ANOVA or Kruskal Wallis were used with post hoc Tukey and Dunn tests, respectively. To determine correlation of variables, Pearson’s linear correlation coefficient or Spearman’s rank correlation coefficient were used.

Results

A total of 50.8% of the subjects had at least one metabolic disorder—most commonly excessive body weight (66.7%) and abdominal obesity (64.3%). Patients did not differ significantly in terms of physical activity, but they did differ in mean time spent sitting—with this being significantly longer for all groups than in the general population. The subjects differed in diet: patients with BD consumed less unhealthy foods than patients with schizophrenia. The highest correlations between physical activity, diet and variables defining metabolic disorders were found in patients with BD. Only in patients with schizophrenia were there significant correlations between the course of the disease and physical activity.

Discussion

The results suggest the existence of associations between diet, physical activity, and metabolic disorders in both BD and schizophrenia patients. They also suggest a tendency among those patients to spend long periods of time sitting.

Heavy metal pollution poses a threat to rainwater which serves as a major alternative source for water for developing cities like Lagos. In the investigated of heavy metal in rainwater, 176 rainwater samples collected directly from the sky were analyzed from 2018 to 2019 during periods of light rainfall (Oct-Nov) and heavy rainfall (April-July). The pH> 5.6 indicated alkalinity. Light rainfall period average value 7.33 and heavy rainfall period 7.4.The MATLAB 7th degree polynomial regression described the relationship between dependent and independent variables for the pollutants. The correlation coefficient, R2 verified that the MATLAB models could accurately predict and forecast. Analysis of Variance (ANOVA) showed p<0.05 for Cadmium (Cd), Copper (Cu), Zinc (Zn), Iron (Fe) and Nickel (Ni), indicating that the probability that rainfall affected their concentration levels was high. The GIS Inverse Distance Weighted (IDW) pollution models revealed that the pollutants were present in the atmosphere throughout the year. It portrayed industrialized areas as the more affected areas thereby identifying anthropogenic activities as the main cause of these pollutants. During heavy rainfall periods hot spots appeared for Cd, Cu, Zn and Ni. In addition, Cd, Cu, Zn, Pb, and Ni were present in high concentration in the rainwater from suburb areas during periods of heavy rainfall. The concentration of heavy metals found in the rainwater follows the order: Fe>Zn>Ni>Cu>Cd>Pb. Cd and Pb exceeded WHO standards. Therefore there is need for rainwater treatment and monitoring by Government Agencies and parastatals to ensure public health and safety.
