Cardiovascular disease risk factors in the Lubelskie Voivodeship in 2008-2018 - part I: tobacco smoking
Authors: Jankowski Krzysztof
Published: September 2022

Background: Smoking is one of the most common cardiovascular risk factors. It is responsible for 7 million deaths annually in the world. Another 1.2 million people die from passive smoking. Nicotinism causes a chronic inflammatory process, oxidative stress, and it also works by increasing adrenergic arousal. The Cardiovascular Diseases Prevention Program implemented by Primary Healthcare Clinics is designed to assess the risk factors for cardiovascular events in patients. This provides an opportunity for an early response and appropriate action.

Methods: A retrospective analysis of data obtained by the National Health Fund as part of the implementation of 86,485 preventive cards of the Cardiovascular Diseases Prevention Program in the Lubelskie Voivodeship in 2008-2018 was carried out. The analyzes were performed using the IBM SPSS Statistics for Windows, version 25 program. The chi-square test and the Pearson linear correlation between the quantitative features were used to test the relationship between the two qualitative features. Significant predictors of a risk factor for cardiovascular disease were determined using multivariate logistic regression. The significance level was assumed to be α = 0.05 for two-tailed tests.

Results: Tobacco smoking was declared by 26.5% of all respondents. It was significantly more often declared by men. The percentage of smokers increased with age - the highest was obtained for the group of 55-year-olds. Smoking cigarettes was significantly more often reported by people with primary education (44%), manual workers (33%) and retirees / pensioners (35%). Smoking tobacco escalated the risk of being diagnosed with arterial hypertension by 16.5%. It significantly influenced the risk of diabetes - even by 33.9%. It raised the risk of hypercholesterolaemia by 17.1% compared to never-smokers as well.

Conclusions: The prevalence of nicotinism is alarmingly high. The effective implementation of the Cardiovascular Diseases Prevention Program provides an opportunity to educate on a large scale and identify patients at high risk of a cardiovascular event. Assessing the risk of death on the SCORE scale can motivate patients to change their lifestyle and make them aware of the impact of smoking on increasing this risk.
Cardiovascular disease risk factors in the Lubelskie Voivodeship in 2008-2018 - part II: the obesity epidemic
Authors: Jankowski Krzysztof
Published: September 2022

Introduction: All over the world, the problem of excess body weight is being raised more and more frequently. In 2021. the number of obese people has tripled compared to 1975. Due to the constantly growing number of people meeting the criteria for overweight and obesity, it is becoming extremely important to implement preventive measures. Cardiovascular Diseases Prevention Program implemented in Poland as part of the National Health Fund program is a good opportunity to identify patients with abnormal body weight and to correct behavior and health education.

Material: A retrospective analysis of data obtained by the National Health Fund as part of the implementation of 86,485 preventive cards of the Cardiovascular Diseases Prevention Program in the Lubelskie Voivodeship in 2008-2018 was carried out. The analyzes were performed using the IBM SPSS Statistics for Windows, version 25 program. The chi-square test and the Pearson linear correlation between the quantitative features were used to test the relationship between the two qualitative features. Significant predictors of a risk factor for cardiovascular disease were determined using multivariate logistic regression. The significance level was assumed to be α = 0.05 for two-tailed tests.

Results: The average BMI value was 26.12 kg / m2. 1st degree obesity was diagnosed in 14.3% of patients, 2nd degree - 2.9%, 3rd degree - 0.7%. Excess body weight was significantly more often observed among men. With the increase in the number of years in the study population, the occurrence of overweight and obesity was significantly higher. One unit increase in BMI was associated with a 13% increase in the risk of high blood pressure and a 12% increase in the risk of serum glucose ≥126 mg/dl. It also increased the risk of hypercholesterolaemia by 4.2% and of elevated LDL levels by 5.5%.

Conclusions: The prevalence of obesity is extremely worrying. Excessive body weight undeniably translates into worse health of the population. The Cardiovascular Diseases Prevention Program at Primary Healthcare Clinics is a convenient opportunity to identify the factors leading to the development of obesity and to promote health-promoting behaviors.

Published: September 2022

In this paper, a hydraulic motor controller is designed with a fuzzy supported integral sliding mode algorithm. The hydraulic system used in the study was modeled using artificial neural networks. Ability of handling nonlinearity of systems makes sliding mode controller to be a good choose for this system. The integral sliding mode controller can supply the robustness the system against the uncertainties. The basic idea of the proposed control method is to use fuzzy logic for the adaptation of the integral sliding mode control switching gain. Such adjustment reduces the chattering that is the most problem of classical sliding mode control. The equivalent control is computed using the radial basis function neural network. Simulation results of the presented method were compared with conventional PID controller results. It proved that it is more efficient to control the hydraulic system with integral fuzzy sliding mode control using neural network.
The Missing Link: Low-Fee Private Tuition and Education Options for the Poor – The Demand-Side Dynamics in Pakistan
Authors: Bano Masooda
Published: September 2022

Low-fee private schools are today recognised as important players in the education market in developing countries, as they are argued to provide at least marginally better education than is on offer in the state schools. Leading international development agencies have begun encouraging governments in developing countries to include them within the policy-planning process. Based on fieldwork in two urban neighbourhoods in Pakistan, this paper shows that low-income parents are keen to secure good-quality education for their children, but they have to choose not only between state schools and low-fee private schools but also from among an array of low-fee tuition providers in their immediate neighbourhood to ensure that the child can cope in class, complete daily homework assignments, and pass exams in order to transition to the next grade. The evidence presented in this paper suggests that whether their child is enrolled in a state school or in a low-fee private school, the parents’ dependence on low-fee tuition providers is absolute: without their services, the child will not progress through the primary grades. Yet the sector remains entirely under-researched. The paper argues for the need to map the scale of this sector, document the household spending on it, and bring it within policy debates, placing it alongside low-fee private schools and state schools in order to provide access to primary education to all and improve the quality of education. At the same time it complicates the existing debates on low-fee private schools, by showing that parents on very low incomes — in this case households where mothers are employed as domestic workers and fathers are in casual employment — find them inaccessible; it also shows that household spending on education needs to take into account not just the charges imposed by low-fee schools, but also the cost of securing religious education, which is equally valued by the parents and is not free, and also the cost of paying the low-fee tuition provider. When all these costs are taken into account, the concerns that low-fee private schools are not truly accessible to the poor gain further traction. The paper also shows that mothers end up bearing the primary burden, having to work to cover the costs of their children’s education, because the core income provided by the father can barely cover the household costs.
Historical Land Injustices in Kenya
Authors: Wanjohi Jackson N. , Kiboi John M.
Published: September 2022

Historical Land Injustices in Kenya have remained a thorn in the flesh. Whenever Kenya goes to a general election after every five years, historical land injustices have acted as a rallying cry for many politicians who use it to woo voters with the promise of ‘returning the land’ or settling land concerns if one is elected. Yet, several regimes that have ruled since independence (1963) have not been able to tackle this issue, as it is considered to be a very emotive agenda. Besides the disputed presidential election of post December 27, 2007 elections, historical land injustices were at the centre as a catalyst against those who were perceived to have benefited from the said injustice. Many people lost their lives, and others were displaced from their respective lands. Various attempts have been made, especially by non-political and Non-Governmental (NGO) bodies, to resolve the problem of land injustices, to no avail. Churches have preached peace; the government has set up commissions like the Truth and Justice, Reconciliation Commission (TJRC), and administrative policies and NGOs have provided for a discussion between elders of different communities. However, hostility against communities related to people who were thought to have been exploited remains afloat. This research article explores the underlying factors that led to land alienation from original owners and the place of the various regimes in land alienation. It then surveys the governments, the Church, and NGOs to attempt to resolve the problem of hostility and demand for the historical land injustices redress. The guiding questions are: Why have the proposed alternatives failed to realize reconciliation among the affected communities? Can the affected communities draw some lessons from the Guest Christology that comes with Zacchaeus encounters in Luke 19:1-10? Can reverse economy, drawn from Zacchaeus’ encounter with Christ in Luke 19:1-10, offer a new paradigm shift in our approach? Are there lessons we can learn from the Jewish Year of Jubilee? The research is basically library based.

Authors: Monira Marjanum , Helal Md. Al , Liton Md. Nurul Huda , Kamruzzaman Md. , Islam Abu Kalam Md. Farid ul , Kojima Seiji
Published: September 2022

We investigate the hydrostatic pressure dependences of elastic, electronic, and optical properties of the newly hypothesized perovskite compound ACuO3 (A = Ca, Sr) using the first-principles method. The structural and mechanical stabilities have been established theoretically under pressure up to 100 GPa. The ductile nature of these transition metal oxides has been confirmed by the calculation of elastic constants. The relatively low-value Young’s modulus possesses high thermal shock resistance and proclaims the materials to be a promising thermal barrier coating material. The partial density of states shows the dominant behavior of Cu-3d and O-2p orbitals at the Fermi level and it implies the subsequent good electrical conductivity. The significant response of the optical properties such as reflectivity, dielectric constant, optical absorption, and loss function with the change in pressure have been noted. The origin of these optical responses is discussed with implications, which can be supportive for future investigations of ACuO3 (A = Ca, Sr).

The COVID-19 pandemic and compulsory isolation measures linked to it inflicted psychological, social, political, and economic effects worldwide. Objectives: The aim of this study was to assess the psychological impact and the mental well-being of Moroccan population during the COVID-19 pandemic. Methods: We conducted a survey using an online questionnaire which collected information on demographic data, living environment, evolution of consumption habits during lockdown, and additional information. Psychological impact was assessed by the Peri-traumatic Distress Inventory (PDI), and the mental well-being was assessed by The Warwick-Edinburgh Mental Well-being Scale (WEMWBS). Results obtained for healthcare professionals were compared to those obtained in the general population. Results: 2273 respondents were included in the study. In total, 31,45% of respondents rated a score of peri-traumatic distress greater than or equal to 15. The average of the mental well-being score was 50.121. Most respondents (79.3%) increased their digital screen time as well as the consumption of coffee, calorie-rich, fatty and sugary foods. Factors such as female gender, psychiatric history and accommodation without a terrace or balcony were significantly associated with a higher psychological impact of the outbreak and higher scores of PDI. Nevertheless, no significant difference in the mental well-being and PDI scores was found between healthcare workers and the general population in our study. Conclusion: During the COVID-19 pandemic in Morocco, about one-third of respondents indicated significant distress. Our findings identify factors associated with a lower or a better level of mental health status that can help us to develop appropriate interventions for managing the psychosocial consequences of pandemic.
Most Appropriate Gestational Age for OGTT amongst High-Risk Pregnant Patients? Need for RCT
Authors: Mahmood Dr. Faisal
Published: September 2022

High risk for gestational diabetes mellitus includes mothers with certain ethnicities, increasing maternal age, mothers with history of high or low birth weights, rising parity, previous macrosomic baby, stillborn baby, a family history or first degree relative with gestational diabetes (GDM) and type 2 diabetes mellitus, history of glucose intolerance or GDM, polycystic ovarian syndrome and maternal obesity. Timely screening, hence intervention can prevent complications of GDM to fetus and mother. Studies investigating, when during pregnancy should this high-risk group be screened, have established that 24-28 weeks OGTT have missed a few early onset GDM cases and booking visit OGTT/12 weeks gestational age OGTT may miss late onset GDM cases. All these studies have either been retrospective or comparison groups have been mis-matched. To date there is no prospective direct comparisons, comparing early OGTT results (12 weeks gestation) and late OGTT results (24—28weeks gestations). Physiologically speaking, stress of pregnancy is higher with advancing age of gestation and 24-28 weeks gestational age OGTT seems appropriate however evidence suggests that a few early onset GDM cases are missed. There is a need for prospective comparison at two different time intervals in same group of these high risk patients to answer this question.

Published: September 2022

In this study, we explored teachers' perceptions of creative students' characteristics and how these perceived characteristics are related to students' school adaptation or creative talent perceived by teachers. To this end, we conducted two studies. Study 1 explored teachers' perceptions of creative students' characteristics. Study 2 examined how the characteristics of creative students affect teachers' perceptions of students by using an experimental vignette method. In Study 1, we collected 25 teachers' perceptions of creative students' characteristics in an open-ended manner. Responses were categorized by a total of 41 characteristics, and a 9-point Likert scale was finally created. The scale was conducted on 204 teachers, and six factors resulted from the exploratory factor analysis. In Study 2, we created 2⁶ (= 64) vignettes using six factors derived from Study 1. A total of 189 teachers participated in the vignette experiment and confirmed how teachers' perceptions of students (i.e., academic achievement, academic motivation, peer relationship, relationship with teachers, intention to recommend creativity nurturing special programs, and the burden of teaching) differed by the characteristics presented in each vignette. Based on the results, the importance of teachers' perceptions in creative education was discussed.

The disturbance of wildlife is one of the problems that are often faced by the community in their cultivation land. In order to overcome or reduce the level of disturbance, the community often complains to field officers from the Regional VIII Forestry Service Branch, Provincial Forestry Service of West Java. In these complaints, the community often asks to be able to capture some of the wildlife population. However, one of the obstacles faced by officers is not knowing how to determine the number of populations that can be arrested. Therefore, training has been carried out for the officers with material consisting of animal inventory techniques, estimation of carrying capacity of habitats, and estimation of the number of animals that can be caught. The officers said that most of the training materials were understandable and useful in answering problems related to wildlife disturbance.

The case of occurrence of a strong wind, which is rare for the winter period, in the gradation of a dangerous phenomenon (≥25 m/s) in the Central Chernozem region (Stary Oskol, Belgorod region) is considered. For comparison, the examples of similar cases of strong wind in the same area in 2008 and 2011 are given. Conditions for the occurrence of the considered dangerous phenomenon are analyzed on the basis of upper-air and satellite observations, as well as using the forecast fields of WAFC London significant weather maps. It is suggested that wind speed has reached the criterion of a dangerous phenomenon when such factors as the passage of active atmospheric fronts and the low-level jet match. Keywords: strong wind, winter period, atmospheric fronts, low-level jet
