The rise of Euroscepticism on the political scene in Poland – the case of the party Law and Justice
Authors: Cymer Klaudia
Published: April 2023

The aim of this article is to analyse the growing phenomenon of Euroscepticism on the political scene in Poland, taking into account the power of the ruling coalition headed by the Law and Justice party. For this purpose, after a brief discussion on the theoretical framework of Euroscepticism, in order to find the reasons for the rise of this phenomenon in Poland in recent years, the current context of the government's relationship with the European Union (EU) is analysed. Consequently, by analysing the political programmes of the Law and Justice party and statements of political actors associated with the main ruling party in Poland, the author verifies the upward trend in unfavourable attitudes towards the EU by current government, as well as consistently appearing considerations of leaving the EU (“Polexit”).
Improving Access to Harm Reduction Services in People Who Inject Drugs at a Rural Health System
Authors: Kaur Amandeep , Williams Karen S
Published: April 2023

Background:

Hospitalists are increasingly responsible for treating infectious complications related to injection-drug use. Despite these complications leading to hospitalizations, harm reduction interventions have not been widely adopted in inpatient settings. Use of naloxone is safe and effective at treating respiratory depression in patients with opioid overdose. The objectives of this study were to assess the need for a multi-modal approach to provide a standard of care in people who inject drugs (PWID), and to create and educate healthcare providers on tools that could improve delivery of harm reduction services.

Methods:

A review of medical records assessed the need for an intervention to increase access of harm reduction services. PWID 18 years or older who presented to the emergency department (ED) or were hospitalized were eligible. After clinician education, investigators utilized prospective audit to assess and re-educate on intervention use. Primary outcome was percentage of naloxone prescription or education provided at discharge. Secondary outcomes included percentage of disease screening, fentanyl test-strips education, safe-injection practice education, vaccination rates, and healthcare provider survey on naloxone.

Results:

Sixty-five patients were analyzed for the baseline group and 15 patients for the post-intervention group. The median ages were 32 years (IQR, 19–64) and 32 years (IQR, 20–56) in the baseline and post-intervention groups, respectively. Naloxone prescriptions and education had an absolute percentage increase of 2.1% and 6.7%, respectively. Secondary outcomes were not analyzed due to a delay in the intervention implementation.

Conclusions:

Barriers to implementation of the intervention led to lack of data for analysis of harm reduction services in PWID in a rural hospital system. Future studies could evaluate other methods to increase these services and assess ways to optimize care through transitions.
THE SEMANTIC ASPECT OF FOOD AS PUNISHMENT AND COMFORT IN THE WORKS BY L. CARROLL, CH. DICKENS AND P. TRAVER
Authors: Didkovska Tetiana
Published: April 2023

The article deals with the semantic aspect of food functioning as punishment/reward and lovelessness/comfort in the English literature of the XIX and early XX centuries in the works by L. Carrol, Ch. Dickens and P. Travers. The research investigates the food motif as a means to reflect eating traditions of a particular historic period and a social marker for the protagonists. The author explores how the writers use eating habits to express acceptance, resistance, emotional affection, taboo behaviour, power and celebration traditions. It is suggested that food imagery is positively related to cultural identity which includes various issues from social position to gender issues. It is shown that the presentation of food in literature can mirror the writers’ own preferences allowing them to tap on their personal experience in the works, thus giving “food” for bibliographers. Recent literary culinary studies have stimulated the development of gastronomic tours on the pages of the renowned writers, the so-called food trails, and theme fests such as the Great Dickens Christmas Fair and Victorian Holiday Party or Whitby’s White Rabbit Trail as part of niche gastronomic tourism in Great Britain. So, the present interdisciplinary research may be of great interest not only for philologists but also for students specializing in tourism and country studies and the general public.

Authors: Mamuladze Merab , M. Lejava  , F. Abuselidze
Published: April 2023

At present, where most of the soils of Georgia have a small contour, the demand for small-capacity technical means, in particular motoblocks, has increased. Motoblocks perform agricultural work for various purposes, where the work process is performed by the operator, who experiences various magnitudes of vibration, impact, noise, and in general, as a result of long-term work production, causes body damage, dynamic load, and respiratory diseases in people. In the scientific paper, the dependence on the vibration of different types of diesel fuel is investigated in the case of five different revolutions in the internal combustion engine. Studies have shown that fuel and engine speed are the only risk factors that contradict the ISO 5349-2(2004) international standard. The experience of four years of work studies showed that 10% of operators received various types of injuries as a result of working with motoblocks. Experiments also showed that the amount of vibration decreases when the number of revolutions of the engine increases, and in the case of using biodiesel fuel, the damage risk factor is 5-10%, and in the case of using conventional diesel, this indicator has gone up to 20%.

Authors: Kaplun Viktor , Osypenko Volodymyr , Makarevych Svitlana
Published: April 2023

The strategy for the development of local low-power systems involves the use of several sources. The efficiency of functioning such systems depends on the purposeful reliability management and it is based on the rational hierarchical connections of their structural components. Coordination of the structure of diversified sources and their participation in the formation of energy balance of micro-energy systems in the conditions of dynamic development of renewable energy is an actual research task. The purpose of research was to develop a method of reliability-cost optimization of structure of micro-energy systems with dissimilar sources, which is based on the use of reliability indicators and cost of electricity. The studies conducted are based on the modern methods of applied statistical analysis, the theory of reliability, the synthesis of complex multi-aggregate systems. Through the implementation of the Markov model and simulation modeling of the functioning of sources, it has been obtained the conditions for optimal formation of the energy balance of micro-energy system with the lowest cost of electricity, considering the reliability indicators. Computational experiments made it possible to obtain the regularities of cost evolution of electricity and to show its dependence on the structure and algorithms of the sources’ functioning. Using a probabilistic modeling method, it has been proved for the first time that the cost of electricity is sensitive to the ratio availability of renewable sources of primary energy. The practical application of results lies in the increase in efficiency of energy islands through the structural and algorithmic optimization of diversified sources (traditional and renewable) based on determining the cost of electricity
Justification of the electrical scheme of biological tissue replacementunder the action of DC voltage
Authors: Kryvonosov Valerii , Prudnikova Nataliia , Martyniuk Lilia
Published: April 2023

The change in the impedance of biological tissue under the influence of voltage is used in the diagnosis and treatment of various diseases. Mathematical models describing physical and biological processes in biological objects are based on electrical substitution schemes. The subject of research of this work was the study of the change in the impedance of biological tissue in the transient process of ionization under the action of DC voltage. An analysis of the known substitution schemes was carried out, the shortcomings of their application were identified when the transient processes of ionization in the tissue under the action of direct current voltage were studied, and the substitution scheme with the introduction of additional resistance was substantiated, both analytically and experimentally. In the work, the bioimpedance method is applied when direct current voltage is applied to biological tissue, taking into account the law of commutation in transient ionization processes. An invasive measurement of the change in impedance with needle electrodes was carried out, and it was proved that the active component proportionally depends on the distance between the electrodes, while the capacitive component remains unchanged. It is shown that the ionization time constant is a criterion parameter and can be used in the diagnosis of the development of ischemic disease of muscle tissue, the change in the state of biological tissue when blood flow is stopped during the application of a tourniquet. It has been proven that the ionization time constant does not change with an unchanged ionic composition of the tissue and can be used in the analysis of the composition of the intercellular space. A simultaneous invasive measurement was performed in two identical places of different limbs, on one of which a hemostatic tourniquet was applied. The obtained results made it possible to conclude that a change in the constant time from 15% to 50% compared to two constant times allows for rapid diagnosis, within 2 minutes, of the state of biological tissue and can be used in the study of the development of diseases associated with ischemia. The results of the study can be used for rapid diagnosis of the state of a biological object and the creation of an inexpensive device for its use in surgery and research laboratories

Authors: Toledo Gotor Cristina , García Muro Cristina , De Pablo de las Heras María , Pasamón García Sara , Salvá Artega Myriam , García Oguiza Alberto
Published: April 2023

Introducción: el síndrome de Aicardi (SA; OMIM #304050) es un trastorno genético raro, cuya incidencia es de aproximadamente 1/100.000. Fue descrito en 1965 como una triada consistente en agenesia del cuerpo calloso, lagunas coriorretinianas y espasmos infantiles. Asocia discapacidad intelectual severa y epilepsia de difícil control. Aunque su espectro clínico es variable, tiene por lo general un pronóstico infausto debido a la elevada morbimortalidad asociada. Se considera un trastorno esporádico causado por variantes patogénicas en heterocigosis de un gen ligado al cromosoma X, que causa mortalidad embrionaria en varones hemicigotos.
Objetivo: este trabajo pretende llevar a cabo una revisión bibliográfica acerca de la literatura científica disponible del síndrome de Aicardi. De esta manera se hará una actualización sobre esta entidad en cuanto a definiciones, prevalencia e incidencia, etiología, espectro clínico y pronóstico de los pacientes afectos.
Materiales y métodos: se lleva a cabo una búsqueda bibliográfica retrospectiva en las principales bases de datos científicas. Para ello, se utilizan las palabras clave “Aicardi”, “agenesia del cuerpo calloso”, “espasmos infantiles” y “encefalopatía epiléptica”.
Conclusiones: desde su descripción se ha ido ampliando el espectro de manifestaciones clínicas del síndrome. Actualmente no se conoce la existencia de un biomarcador que posibilite el diagnóstico, por lo que éste continúa siendo eminentemente clínico. Se debe tener un alto nivel de sospecha en espasmos infantiles de debut precoz mujeres con alteraciones en neuroimagen.

Published: April 2023

The purpose of this work is to reveal the patterns of formation of the structure of the surface layer of high-chromium steel subjected to nitriding in a low-pressure gas discharge plasma using a plasma generator with a hot cathode "PINK". Heating of the samples to the nitriding temperature was carried out by the ionic component of the plasma, as well as by the electron and ionic components of the plasma (elion mode). The object of the study was heat-resistant corrosion-resistant steel of the austenitic class grade 20X23H18 (foreign analogue of AISI310S). The relevance of research is due to the relatively low level of hardness and wear resistance of steels of this class. Nitriding of steel was carried out on the TRIO installation, retrofitted with a switching unit for implementing the aelion (electronic and ionic) processing mode. It has been established that the thickness of the hardened layer is (55-60) pm and weakly depends on the method of nitriding, temperature (in the range of 793-873 K), and duration (3-5 hours) of the process. A nitriding regime has been revealed that makes it possible to form a surface layer with a microhardness of 13.7 GPa (ionic heating mode) and 10.8 GPa (elion heating mode). It has been established that the high strength and tribological properties of nitrided steel are due to the formation of a nanocrystalline structure in the surface layer, the main phases of which are iron nitrides Fe4N and chromium nitrides CrN. It is shown that heating the samples to the nitriding temperature in the aelion mode, which uses the electron and ion components of the plasma, leads to a significantly lower level of material roughness compared to the samples heated during nitriding by the ion component of the plasma.
Influence of magnetic field on the dielectric characteristics in manganese sulfide substituted with thulium

Published: April 2023

The properties of a solid solution of thulium-substituted manganese sulfide prepared by melting the initial pure samples of manganese sulfide and thulium sulfide are studied. X-ray diffraction analysis was carried out. The face-centered cubic lattice is determined, and the decrease in the intensity of the peaks is found. Dielectric permittivity was measured in the frequency range 102106 Hz and temperatures 300-500 K in magnetic fields up to 12 kOe in TmxMn1xS solid solutions (0 x 0,15). From the frequency dependence of the permittivity, the relaxation time and the relaxation mechanism of the dipole moments are found. The leakage current is excluded, and the contribution of migration polarization due to charges in the region with chemical phase separation is estimated. Die real and imaginary components of the permittivity of TmxMn1xS samples are described in the Debye model. The maximum of the imaginary component of the permittivity shifts towards higher frequencies upon heating, and the relaxation time is described by the Arrhenius function. Dielectric losses are caused by electron-phonon interaction. The frequency of the crossover from Debye relaxation to relaxation conduction associated with the absorption and emission of phonons is found. Die crossover frequency increases as the sample is heated according to a power law. In a magnetic field, the permittivity decreases and the largest change of 2.5 % is achieved at T = 450 K. At other temperatures, the magnetocapacitance does not exceed 0.5 %. The shift of the maximum of the imaginary component of the permittivity to low frequencies in a magnetic field leads to a change in the sign of dielectric losses from positive to negative. A qualitative difference in () is established in the vicinity of the concentration of thulium ion flow through the FCC lattice, where the permittivity is not described in the Debye model and there is no magnetocapacitance. The mechanism for reducing dielectric losses in a magnetic field is determined.

Published: April 2023

The stages of the future physical education teachers career formation in the Ukrainian higher education system are analyzed, the content and structure of the future physical education teachers career formation are defined and proved; the most essential directions in improving the content structure of sports and teacher education are highlighted.

Social and political processes taking place in the modern Ukrainian society show that the faster it moves through scientific and technological progress, improving the welfare of citizens, the more significant is the question of formation the spiritual, mental and physical health of the future teacher, in particular the specialist in physical education. However, in addition to acquiring profound professional knowledge, specialist in physical education should be able to demonstrate his citizenship position and defend the public interests, build and assert personal relationships, self-assert in the process of professional activity, and fully meet the level of modern requirements imposed by new social and economic conditions of modern Ukrainian society. The concept of «pedagogical conditions» is extensively used in the dissertations on the problems of future specialists’ professional training, and therefore it is considered to be appropriate to conduct a deeper methodological analysis of the phenomenon.

Analysis of psychological and pedagogical literature indicates that the formation process of any skill can be effectively realized only under certain conditions that reflect its essence and specificity. It is well known that any science as a special form of thought, awareness of a sphere of objective reality has its own peculiar categorical apparatus.

There are many scientific approaches to the interpretation of the term "condition". In philosophical dictionary, the term "condition" is considered as a factor (Lat. Factor), that is the driving force, the reason of any process.

У статті обґрунтовано актуальність проблеми формування і розвитку  управлінської компетентності майбутніх офіцерів поліції, яка входить до складу сектору безпеки й оборони України. Дано визначення понять «управління», «управлінська компетентність». Управління - це  вид людської діяльності, що полягає у свідомому та цілеспрямованому впливі на людей, об’єкти і на процеси з метою надання їм бажаних параметрів функціонування та розвитку. Управлінська  компетентність – це інтеграційна якість особистості, яка наділена функціями управління, поєднує істотний інструментарій ефективного здійснення управлінської діяльності, представлений мотиваційно-ціннісними, світоглядними, комунікативними складниками (знаннями, вміннями, навичками та здібностями тощо), вираженими в термінах спостережуваної поведінки. Показано, що управлінська компетентність має власну складну структуру. Визначено специфічні функції, які виконує особа, яка здійснює управлінську діяльність.   Тому процес формування управлінської компетентності безпосередньо пов’язаний з оволодінням управлінськими вміннями й навичками, які забезпечують компетентне виконання управлінських функцій. Представлено результати експериментального дослідження формування управлінської компетентності у майбутніх офіцерів поліції у процесі їх  професійної підготовки. Виявлено статистично вірогідну наявність позитивної динаміки за більшістю показників в експериментальних групах після вивчення спецкурсу, написання курсових і творчих робіт, участі у тренінгу.

У статті представлені результати дослідження показників рухової активності учнів Сумського регіону після впровадження комплексу заходів з оптимізації фізкультурно-оздоровчої діяльності у навчально-виховний процес закладів дошкільної освіти. На теренах сьогодення досить гострою проблемою постає питання низьких показників фізичного здоров’я учнів дошкільних навчальних закладів. Сучасна педагогіки та педіатрія б’є на сполох щодо зміни вектору у напрямку омолодження, цілої низки хвороб, пов’язаних з навчанням у дитячих садочках, через зниження кількості фізичної активності учнів, які протягом навчального періоду займаються підготовкою до умов навчання у закладах загальної середньої освіти. У цьому переліку ми знаходимо наступні діагнози: вади опорно-рухового апарату, проблеми органів зору, серцево-судинної та дихальної систем, дерматологічні хвороби, інфекційні хвороби тощо. Зниження кількості рухової активності дітей протягом перебування у дитячому садочку призводить до негативної динаміки показників фізичної підготовленості, що суперечить генетиці і фізіології розвитку майбутніх школярів. Зрозумілим є і той факт, що через відсутність на заняттях через хворобу, не залежно від її етимології, під час навчально-виховного процесу учні недоотримають повного об’єму необхідних знань для подальшого навчання у закладах загальної середньої освіти. Що автоматично призводить до проблем з навчанням у подальшому. Ще однією проблемою, яка негативно впливає на рухову активність дітей, є байдуже ставлення вихователів до занять фізичною культурою з наданням преференцій інтелектуальному вихованню. Для вирішення окреслених проблем авторський колектив розробив комплекс заходів щодо оптимізації процесу фізкультурно-оздоровчої діяльності учнів під час перебування у дитячому садку. Комплекс представлений ігровими практиками з використанням спортивних і рухливих ігор, у які можна грати під час навчального процесу і будучи вдома на свіжому повітрі.
PECULIARITIES OF THE PROFESSIONAL TRAINING OF FUTURE PHYSICAL CULTURE TEACHERS AND TRAINERS IN THE CONDITIONS OF DISTANCE EDUCATION
Authors: CHERNYAKOVA Zhanna , LIANNOI Mykhailo , BAKATOV Vladimir , KHOLODNIY Аlexandr
Published: April 2023

In the article the modern challenges faced by the higher education system in Ukraine due to the pandemic and Russian military aggression are analyzed. The advantages and disadvantages of implementing distance education in the conditions of modern emergency and crisis situations in the country are presented. Particular attention is devoted to the description of the advantages and disadvantages of the professional training of higher education students of the specialties 014 Secondary Education (Physical Culture) and 017 Physical Culture and Sports in the conditions of distance learning. Attention is focused on the fact that despite all the benefits of the distance learning system, future physical culture teachers and trainers do not have the opportunity to qualitatively master the rational technique of movements from various sports. Despite access to video materials with a demonstration of the reference technique for performing the exercise as a whole and its individual elements, students have limited opportunities for its high-quality consolidation and practice. When students independently study the technique of movements, the teacher does not always can correct technical errors and provide meaningful methodical recommendations, which as a result can lead to the formation of stereotypically incorrect movements of the students of the specified specialties when performing certain exercises. In this context teachers of practice-oriented disciplines are recommended to actively use modern digital technologies and other forms of digital technologies in their work, which allow correcting errors in the execution of exercise techniques and monitoring the physical activity of each student in real time. Despite a few shortcomings of the distance learning system, it remains the only alternative and safe form of obtaining higher education in Ukraine and an effective tool for realizing the constitutional right of the citizens to obtain education and professional qualifications.

Published: April 2023

Balikpapan City is a city that often experiences floods. One of the most frequently flooded locations is Gang Mufakat, which is located in Damai Village, South Balikpapan. This area is an area passed by the Ampal River Basin which is one of the causes of flooding besides the lack of vegetation as land cover in the settlement. This research aims to identify the management and control/control of floods in general. This is done to obtain information on several things that are considered important in management and to assess the understanding of the community and government regarding flood control/management. The research method used is a descriptive qualitative method. This research results from the community's understanding of floods and community actions in dealing with floods. Understanding of flooding in the form of causes of flooding, and the importance of the role of vegetation on land cover and the creation of infiltration wells. The recommendation for the government is to dredge sedimentation as well as deepen the Ampal watershed, and create a polder as a substitute for water catchment areas because there are many residential areas around the Ampal watershed which do not allow water to flow directly into the watershed. The recommendation for the community is to build an infiltration well in the Gang Mufakat.
The Implementation of Sustainable Development Goals for North Korea: An Assessment of Its Compliance with No Poverty Goal
Authors:   Korea Association of International Development and Cooperation, Yi Jisung , Kim Seokwoo , Kim Jiyoung
Published: April 2023

Purpose: Based on the compliance theory and the institutionalist approach, this article is intended to assess North Korea’s compliance levels of No Poverty goal under the Sustainable Development Goals (SDGs).
Originality: Although SDGs stands for advanced global norms, its application constitutes significant challenges for the developing world. For the better achievement of SDG within the global community, this paper highlights country-specific limitations and opportunities for SDG compliance and implementation through the case of North Korea.
Methodology: For the analysis, this study conducts content analysis on a range of documents and information released by the North Korean government, including the Voluntary National Review (2021) and the Multiple Indicator Cluster Survey (2018). In order to evaluate the direct and indirect availability of poverty data (including estimates), relevant academic works and reports are also reviewed.
Result: To assess and explain North Korea’s weak compliance, this study does not stick to the issue of statistical capacity only. For incorporating the wider institutional contexts, the localization of the global discourse on poverty and the internal structure for SDG implementation are also highlighted. Despite the country’s willingness, due to the communist tradition as well as regime justification, we interpret that the country still shows strategic but roundabout behavior in adopting the global concept of poverty.
Conclusion and Implication: This study concludes with recommendations that can help North Korea improve its compliance with the SDG.
The Validity of the Growing Disciples in Community Model Among Adolescents in Seventh-day Adventist Schools in North America
Authors:   ,   Andrews University, Beagles Kathleen
Published: April 2023

Purpose of the Study. There is little empirical research about discipleship, and particularly discipleship and adolescents. An understanding of Christian discipleship might, however, be an antidote for a growing trend toward consumer mentality in the church, the effect of post-Christian culture on the home, and the departure of the younger generations from active church life, which are all seen as problems that face Western Christianity. The purpose of this study was to examine the validity of a discipleship model—Growing Disciples in Community. Method. A conceptual model of discipleship and discipling based on theology and social science theory is developed and tested for its validity. Using Amos 7, the theoretical model was tested using confirmatory factor analysis (CFA) and structural equation modeling (SEM) with a large dataset of some 11,000 cases of adolescents attending private schoolsoperated by the Seventh-day Adventist Church in North America. The primary objective was to determine whether thetheoretical covariance matrix is consistent with the empirical covariance matrix. Results: 1. The theoretical covariance matrix and the empirical covariance matrix were found to be consistent, which indicates that there is empirical support for the Growing Disciples in Community model. 2. There were found to be significant relationships (correlations) among the variables of the model. 3. The validity of the model was also found to be stable across demographic characteristics such as gender, ethnicity, grade levels, and even at-risk behaviors. Conclusion. The Growing Disciples in Community model includes concepts of connecting, understanding, and ministering, which are considered processes of personal discipleship. The model indicates that the discipling attitudes and behaviors of family, friends, Christian teachers, and the local congregation (equipping) help explain adolescents’ responses to the indicators ofpersonal discipleship. Intergenerational connectedness with other Christians has a strong impact on adolescents’ connecting with God and others, understanding and appreciating God’s relationship with humanity, and ministering to and serving others around them. Intentional efforts within the local church to develop and strengthen healthy and appropriate intergenerational relationships will support and benefit the discipleship of all members, not only adolescents.

Problem. Parenting among immigrants presents unique challenges to parents whose cultural orientation is different from the host culture. Because of the meager research literature on immigrant families in the USA, little is known about the phenomenon of parenting among sub-Saharan African immigrant parents. This study investigated the patterns related to the parenting practices of selected sub-Saharan African immigrant parents, how they conduct corrective discipline to their children, and the challenges they face rearing children in Southwest Michigan. Method. Qualitative research methods including interviews, observations, focus group discussions, and artifact collection were used in this dissertation to generate data. A snowball strategy was applied to acquire a sample of 14 families from a community of sub-Saharan African immigrant families that lived in Southwest Michigan and were rearing school-age children. Participants were immigrant parents from Kenya, Rwanda, and Uganda, and had lived in the USA for at least 5 years. Data were analyzed by using the research question approach. Results. Results revealed that lack of time for the children and continuing influences from the participants' cultural and ideological backgrounds characterized the parenting patterns that emerged from the data. Parents reported using non-physical methods to discipline their children. Cultural conflicts, the demands of new lifestyles, and lack of parenting resources emerged as the major themes representing the challenges faced by sub-Saharan African immigrant parents in Southwest Michigan. Conclusion. Cross-cultural parenting creates a tension between a desire to retain the old ways and pressure to change to new ways of parenting. A multi-cultural approach to parenting is recommended for immigrant parents to take advantage of the positive values from both cultures. Parent training and the creation of support groups are needed to aid the transition of immigrant parents into the American culture.

Problem. The purpose of this study was to explore the factors that influence academic success among Haitian-American women. Methodology. A survey research method was used in this study. A quantitative approach was taken when analyzing the data. For this study, 213 Haitian-American women with college degrees completed the Inventory of College Success for Haitian-American Women. One descriptive analysis was conducted and 10 hypotheses were tested by one-way ANOVA. Results. This study examined 16 dependent variables and 10 independent variables with 10 hypotheses. The results indicated that Haitian-American women perceived self-motivation, financial assistance, accessibility to resources, self-perception, time management, spiritual life, family support, prior academic achievement, and affordability of college tuition to be the factors that contributed to their educational success. Knowledge of a second language was perceived as the factor that contributed the least to their educational success. The groups studied revealed more similarities in their responses on the factors than differences. Conclusions. The objective of this study was to shed light on those factors that contributed to the success of Haitian-American women who pursued and obtained college degrees. Nine factors were identified as the key elements that contributed to the educational success of Haitian-American women. The nine factors are self-motivation, financial assistance, accessibility to resources, self-perception, time management, spiritual life, family support, prior academic achievement, and affordability of college tuition. The other factors were not identified as being important contributors to the success of Haitian-American women.

Problem. The Regional officer of Matabeleland North region in Zimbabwe was concerned over the poor student pass rates in these regions. The Education Director of the Zimbabwe Union Conference of Seventh-day Adventists also voiced the same concern about the poor student pass rates, especially in the West Zimbabwe Conference, which is comprised of Matabeleland North, Matabeleland South, and Bulawayo regions. The purpose of this study was to investigate the perception of teachers on student support and student factors that influence the academic performance of students attending Seventh-day Adventist secondary schools in Zimbabwe, focusing mainly on school, community, and student factors. Method. I developed an instrument that was distributed to all the teachers in the 25 Seventh-day Adventist secondary schools in Zimbabwe. Twelve schools ended up participating in the study and 164 questionnaires were returned. Descriptive statistics were used to investigate the factors perceived to be manifested in the schools. A descriptive study was also done to analyze the responses according to the different regions and to investigate the factors that were manifested and not manifested in each region. One-way analysis of variance and t tests were used to determine demographic differences in the perception of teachers concerning systemic factors that affect student performance in the Seventh-day Adventist schools. Results. The student support factors related to student academic performance perceived by the teachers to be manifested in the schools were: good curriculum, positive school climate, teacher professional development, administrative support, and teacher support factors. Teachers also perceived that the students were well disciplined and that they were well motivated to learn. They felt that there was no community support and that the transportation system was poor. Teachers perceived that the students were lacking in physiological needs. Conclusions. The teachers in the Seventh-day Adventist schools in Zimbabwe perceive that the transportation and community support are lacking in the schools. The regions with the lowest student pass rates also had the least acceptable variables for student support and student factors. This study is important for the Education Director of the Zimbabwe Union Conference of the Seventh-day Adventist organization and also for the Ministry of Education, which have to devise ways to improve the academic performance of all students in Zimbabwe.

Background: Acute and subacute toxicity screenings of medicinal plants are the fastest way to evaluate the toxicological profiles of medicinal plants. It helps to have a quick idea of the harm or safety potency of drugs. This study aims to conduct an acute and subacute oral toxicity study on the Cyperus Papyrus (CP) ash in Wistar albino rats. CP is traditionally used for managing painful spasms, eye diseases, ulcers, fever, diarrhea, and inflammations. Further study is required to reflect the safety profile of this plant ash. Methods: Acute oral toxicity study of the CP ash was evaluated by using a dose of 2000 mg/kg body weight on rats according to the Organization for Economic Co-operation and Development (OECD) guidelines using the Aot425 software. Subacute oral toxicity was carried out on 4 groups of 6 rats, at doses of 175 mg/kg, 550 mg/kg, 1750 mg/kg, and 1750 mg/kg. The recovery group (control group) received water according to OECD 407 guidelines for consecutive 28 days. At the end of the experiments (day 29), all rats were weighed and sacrificed except the rats of the recovery group which were continued without ash administration for extra 14 days and then weighed and sacrificed. Subsequently, the hematological parameters, plasma biochemical parameters, and histopathological examination were carried out. Results: Upon completion of the acute toxicity, no deaths or signs of acute oral toxicity were observed. Hematologic observations after oral subacute toxicity included a decrease in hematocrit percentage, mean corpuscular volume, and lymphocyte percentage, while there was a slight increase in the mean corpuscular hemoglobin concentration, however, it returned to the normal range in the recovery group. Biochemical tests showed a mild increase in the serum creatine and aspartate aminotransferase levels but they also returned to their normal range in the recovery group. No morphological changes in the kidney, liver, lung, spleen, heart or small intestine were observed after the histopathological examinations. Conclusion: Dried ash of CP is considered to be safe and non-toxic at acute exposure and as the lethal dose 50% value exceeds 2000 mg/kg body weight, it has a mild reversible effect on some hematological and biochemical parameters while no morphological changes of vital organ histopathology occur.

Background: The effects of Pb-induced neurotoxicity have been largely established; however, the need for proper neuroprotective agents to mitigate the effects of Pb-induced neurotoxicity remains vague. Objectives: This study aimed at investigating the neuroprotective effects of pre-treatment with vitexin and C. cajan extract against Pb-induced neurotoxicity in Wistar rats. Methods: Twenty-four male Wistar rats were randomly assigned into four groups (n=6). The control group was administered 0.5 mL of distilled water, Pb group received Pb acetate (200 mg/kg), vitexin+Pb group received Vitexin (50 mg/kg) an hour before Pb acetate (200 mg/kg), and C. cajan+Pb group received C. cajan (50 mg/kg) an hour before Pb acetate (200 mg/kg). All treatments were done within 28 days. Barnes maze test and novel object recognition (NOR) test were done to ascertain working memory, while the levels of oxidative stress markers (MDA, SOD, and GPx) were also tested. In addition, prefrontal cortical sections were stained with H&E stain, and the immunoreactivity of Iba1 and Nrf2 was examined. Results: There was a significant decline in working memory in the Pb group, but good working memory was maintained in vitexin and C. cajan pretreated groups. In vitexin and C. cajan pretreated groups, oxidative stress, neuronal damage, and expression of Iba1 were significantly low compared to the Pb group. Also, Nrf2 expression in the Pb group was significantly low compared to other groups. Conclusion: Pretreatment with vitexin and C. cajan offers neuroprotection against Pb toxicity via antioxidant and anti-inflammation actions. Although both vitexin and C. cajan extract showed neuroprotective abilities, vitexin exhibited better results.

Optical  Burst  Switching  networks  are considered  as  an  important  candidate  for  the  futuretransport  networks.  As  the  size  of  network  increases conventional  methods  used  in  teletraffic  theory  to model  these  networks  become  computationally difficult  to  handle  as  the  state  space  grows exponentially. In this paper, we have applied overflow theory analysis to model these networks. We proposed a method on how to calculate the blocking probability at core node OBS using equivalent random theory.
