Authors: Belay Senait , Sheferaw Desie
Published: February 2023

The study aimed to estimate the prevalence of ovine Eimeria infection, assess the associated risk factors, and the intensity of infection. A cross-sectional study design was employed and the study was conducted from November 2017 to May 2018. A total of 422 sheep were selected by systematic random sampling technique, and from these animals, faecal samples were collected and examined for Eimeria oocysts. Of the selected and examined sheep 132 (31.3%, 95% CI=26.8-35.7) were found infected by Eimeria species. The prevalence of Eimeria infection was significant (P <0.05) higher in lambs/young than the adult, in females than males, and in poor body condition than in medium body condition sheep. Moreover, the prevalence of Eimeria infection was significantly (P <0.05) higher in sheep with soft faeces than in normal faeces sheep and semi-intensive than extensive sheep production. The intensity of Eimeria species infection was influenced by the age, sex, body condition, fecal consistency, and production system of sheep (P< 0.05). The overall mean Oocysts per gram of faeces was 2390.6 (95% CI=2007.5-2773.8). The mean OPG was significantly higher in lambs, with poor body conditions and female sheep. In addition, it was higher in sheep with soft faeces and an extensive production system. In conclusion Eimeria species infection was an important problem of sheep production in the study area. Generally, this study's results provided useful information to design and implement appropriate control strategies. Finally, it is recommended that further study identify the species of Eimeria circulating in the areas.
Rethinking God’s Omnibenevolence and Omnipotence in Light of the COVID-19 Pandemic: An African Perspective
Authors: Gwara Joyline , Ogbonnaya L. Uchenna
Published: February 2023

The reality and severity of the COVID-19 pandemic question God’s omnibenevolence and omnipotence. Two questions that stare us in the face are a) is  God omnibenevolent given the current reality? b) is God omnipotent? This paper addresses these questions from the African place using the African  theory of duality and its underlying logic, Ezumezu. We argue that the reality of the COVID-19 pandemic and its adverse effects (such as death, hardship  and social isolation) do not negate God’s benevolence and powerfulness. We assert that while the current reality cannot sustain a defence of the  traditional theistic qualities of omnipotence and omnibenevolence, the notions of a powerful and benevolent God are not necessarily undermined by the  reality of Covid-19. In the light of the African theory of duality and Ezumezu logic, we contend that the COVID-19 pandemic brings out the argument that  inherent in God’s benevolence is wickedness and inherent in God’s powerfulness is weakness.
The Concept of God in Igbo Traditional Religious Thought
Authors: Ojimba Anthony Chimankpam , Chidubem Victor Iwuoha
Published: February 2023

This paper examines the concept of God in traditional Igbo-African religious thought, prior to the advent of Western religion, with a view to showing that  the idea of a God/Deity who is supreme in every area of life and sphere of influence and who “creates out of nothing,” like the God of the Christian or  Western missionaries, is unrecognized in the Igbo-African traditional religious thought. Even though the Igbo conceive of strong and powerful deities  that can only reign supreme within their respective sphere of influence where they are in charge, none of these deities is identical to the supreme God  promoted by the Christian missionaries. The Igbo traditional religious worldview maintains a polytheistic religious view, unlike the monotheistic outlook  of the Christian religion. To achieve its goal, the paper adopts the method of historical hermeneutics and textual analysis.

Effects of Annular-finned Tube Deformation on Thermal Stresses in a Heat Exchanger
Authors: Kashani M. , Hatami A. , Hosseini M.
Published: February 2023

Nowadays, along with the developments in the industry, many machines and structures are exposed to very high-temperature environments, which has caused various types of thermal load in them. These conditions have led to focused studies on thermal stresses in structures. Heat exchangers are among the structures in which the temperature difference causes thermal stress. In this paper, “finite volume” and “finite element” methods are used to solve flow equations and thermal stress equations in solids, respectively. In addition, the effect of changes in the shape of the annular finned pipe on the thermal stresses in the heat exchanger is investigated. The study results on changing the pipe shape from circular to elliptical show that by changing the pipe shape, the thermal stress in the fin can be significantly reduced; for instance, in the cases reviewed in this paper, the thermal stress has decreased by 9%. Furthermore, the results of thermal stress show that the Maximum Effective Stress point, both before and after changing the shape, is still located at the fin’s base. So, according to the results of this study, examining the effect of pipe shape changing on thermal stress is an imperative measure when designing heat exchangers.

Authors: Okonkwo J.E. , Okonkwo J.E. , Egbai J.C.
Published: February 2023

This study examines the aquifer properties and lithological structure of Abraka, Nigeria, specifically the Delta State University Site I and III environs. Ten Schlumberger geoelectric soundings, geophysical well logging and pumping test method were employed using an ABEM Terrameter. A drilled water well and existing borehole data were used for this study. The result of the lithological study revealed that the subsurface formations consist of topsoil, lateritic sand, fine and medium grain sand mixed with clay. The topsoil is brownish with thickness of 2 m, the laterite is reddish with thickness of 4 m, the fine sand is whitish with thickness of 10 m, and the medium sand is also whitish with thickness >12 m. The results of the evaluation of the geoelectric data using curve matching and Win Resist computer iteration was in strong agreement with that of the well record, with a subsurface that is composed of 4 to 6 geo-electric layers. The depth ranges from 13.5m to 97.8m while the resistivity ranges from 1021.2 Ωm to 9092.4 Ωm. A core soil sample collected at an interval of 5m, spontaneous potential and resistivity logs were carried out on the well. The hydraulic conductivity, well's transmissivity, storativity, and specific capacity are 102.7m2/day, 5.14 m/day, 0.00062 and 0.39 m3/m respectively. It is recommended that a drill depth of 30 m and above should be accessed for potable water in the area. From the result of this survey, we infer that this aquifer is confined and capable of supplying the people with adequate and good quality drinking water.

Authors: Osiname B.J. , Chukwu U.J. , Duru R.U.
Published: February 2023

Disposal of produced water obtained from crude oil could be challenging and tough because of the effect it has on the environment. Produced water contains high levels of salt and toxic substances which must be treated before re-use or disposal to reduce their impact on the environment, people and assets. Hence, the characterization of produced water for its chemical composition is essential. This study presents the determination of heavy metals (Co, Cu, Pb, Fe, Zn, Ni, and Cd) in produced water obtained from crude oil emulsion samples via inductively coupled plasma optical emission spectrometry (ICP-OES). The samples were subjected to treatment prior to analysis. The analytical curve obtained from the calibration gave excellent correlation coefficients ranging from 0.9995- 1.000 and the recovery values obtained were very good (95% - 105%). The result of the heavy metal analysis in μg/l (Co: <DL to 14.3, Cu: 114.1 to 1553.2, Fe: 492.1 to 1576.4, Ni: 52.3 to 174.5, Pb: <DL to 15.1, Zn: 92.4 to 432.9, Cd: 2.3 to 4.4) indicates that the concentrations of the metals evaluated in the produced water samples were above the recommended discharge limit ( Zn - 1.0 mg/L, Co - 0.02 mg/L, Fe - 1.0 mg/L, Cu - 0.02 mg/L, Cd - 0.01 mg/L, Ni - 0.03 mg/L and Pb - 0.05 mg/L).

Published: February 2023

There has been a low productivity experienced by rice farmers in South Eastern Nigeria as a result of high infestation of pests and diseases caused majorly by fungal pathogens. This research was aimed at pulling together the fungi pathogens associated with rice plants through a comprehensive survey in such a way that one could see at a glance what the problems of fungi diseases look like in the zone. Two middle diagonal lines were drawn (in each plot of rice at distance of 20 cm) along the transverse and sampled. Disease incidence was assessed by visual observation of rice diseases in the fields. Data collected were subjected to ANOVA in RCBD using Gen Stat. 7.2 DE version (2007). Mean separation was done using Fisher’s Least Significant Difference (F-LSD) at 5% level of probability. Incdence and severity of rice diseases was as high as 98.60% and 3.20, respectively. The most important diseases were seed rot caused by Fusarium moniliforme followed by leaf rot caused by Helminthosporium oryzae. Fusarium moniliforme was the most frequently occurring. Out of the fungi belonging to nine genera Fusarium moniiforme was highest in Abia, Helminthosorium oryzae was highest in Anambra,State and Trichoconis padiwickii was highest in Ebonyi. Phoma oryzae occurred most in Enugu State while Fusarium oxysporim was highest in Imo state.
Процес електрошлакового наплавлення з використанням електродних порошкових дротів
Authors: Рибалко Іван , Сайчук Олександр , Захаров Андрій , Боровик Олена
Published: February 2023

У даній роботі розглянуто технологію та техніку електрошлакової наплавки, а також приклади промислового застосування електрошлакової наплавки. Цей процес заснований на виділенні тепла електричного розряду у ванні розплавленого флюсу. Електрошлакова наплавка використовується для виготовлення біметалічних деталей, а також для отримання зносостійких покриттів. У процесі наплавлення електричний струм проходить через розплавлений зварювальний флюс, у результаті виділяється тепло, необхідне розплавлення кромок деталей і електрода. Електрод подається у ванну, що складається з рідкого флюсу, обмежену поверхнею, що розплавляється, і спеціальним формуючим пристроєм. Формуючим пристроєм можуть служити графітові, мідні або сталеві накладки. Флюси, що застосовуються, повинні мати певну в'язкість і електропровідність. При використанні флюсів з малою окислювальною здатністю мають місце незначні втрати легуючих елементів наплавлення. Електродами для наплавлення можуть бути зварювальні дроти, стрічки або стрижні великого перерізу. Температура внаслідок низької електро- та теплопровідності досягає більше 2000°С. Швидкість плавлення електрода дуже велика, коефіцієнт плавлення досягає 30 г/А ч., втрати на розбризкування практично відсутні.Кращі умови для наплавлення основного металу та отримання глибокої шлакової ванни створюються при вертикальному положенні шва, тому електрошлакове наплавлення найчастіше застосовують у поєднанні з примусовим формуванням зварювального шва. Наплавлення починають і закінчують з фіксацією деталі на спеціальних технологічних планках, які потім видаляють з деталі. На початку, поки процес ще не встановився, наплавлений шар може бути недостатньої якості, ця частина шва і залишається на початковій планці, в кінці шва планки застосовуються для виведення усадкової раковини.
Чи любите Ви дітей? (Самооцінка педагогом власних почуттів до дітей)
Authors: Артемова Любов , Борова Валентина
Published: February 2023

У статті висвітлено результати 5-и річного лонгітюдного дослідження проблеми любові дорослих  до дітей раннього і дошкільного віку в умовах сім’ї та в контексті педагогічно спрямованого виховання в умовах сучасних  закладів дошкільної освіти. Зібрані, проаналізовані й інтерпретовані теоретичні дослідження і практичні факти проявів любові до дітей чи її відсутності у дорослих засвідчують важливість і необхідність дослідження цієї проблеми. Концепцію дослідження побудовано  на засадах особистісно зорієнтованого підходу, який реалізовувався в самооцінці та самоаналізі діяльності педагогом закладу дошкільної освіти. Встановлено, що діти з раннього віку потребують любові дорослих. З віком ця потреба зростає і усвідомлюється дошкільнятами. Діти прагнуть і очікують любові від дорослих і страждають, не отримуючи її  в достатній повноті. Водночас виявлено, що професійні педагоги не дооцінюють власну спроможність на любов до вихованців і відповідно -  не всі задовольняють  цю нагальну потребу дітей. Запропоновано долучити  до програми самовдосконалення професійних умінь і навичок виховательки: підвищення рівня дієздатності способів спілкування, опанування нових способів взаємодії з вихованцями, пошук індивідуальних способів ефективного спілкування. Встановлено, що вербальне спілкування з дітьми має проходити за допомогою  зрозумілого доброзичливого мовлення з виразною вимовою слів і речень та мімікою обличчя, що викликає довіру та бажання налагоджувати  дружні взаємини. Діти раннього дошкільного віку мають постійну потребу в тактильних відчуттях, що підсилюють задоволення від ласки та любові дорослих і намагаються задовільнити свою потребу в них. Опрацьовані, досліджені  і рекомендовані інструменти самоаналізу і самооцінки  педагогами власних  проявів любові чи байдужості до дітей доцільно використати, щоб  збагатити гуманними позитивними емоціями спілкування дорослих з дітьми у процесі різних видів професійної діяльності.
Особливості смисложиттєвих орієнтацій студентської молоді
Authors: Бондаренко Наталія
Published: February 2023

В статті представлено результати дослідження особливостей прояву смисложиттєвих орієнтацій студентської молоді. Актуальність дослідження смисложиттєвих орієнтацій в студентському віці визначається вирішальним значенням цього вікового етапу людини в формуванні ціннісної системи особистості і власного світогляду, які відкривають подальшу можливість творення внутрішньої, автономної системи особистісних орієнтирів і змісту ціннісно-смислової сфери особистості. Аналіз наукової літератури дозволив виділити основні напрями щодо визначення смисложиттєвих орієнтацій: складні соціально-психологічні утворення, які спричинені життєвими взаємовідносинами між людьми; детермінанти напряму з межами самореалізації; наслідок визначення життєвих цілей згідно з певною системою цінностей, пов’язаних із ідеєю самореалізації, яка конкретизується у життєвих планах та стратегіях. Емпірично досліджено особливості прояву смисложиттєвих орієнтацій студентської молоді. Виявлено, що досліджувані студенти характеризуються усвідомленістю життя, наявністю цілей у майбутньому, сприймають процес свого життя як цікавий, емоційно насичений і наповнений змістом. Водночас, вони недостатньо мірою задоволені особистою самореалізацією та прожитою частиною життя, не переконані у власній спроможності контролювати події свого життя, вільно приймати рішення та втілювати їх у життя. Здійснено порівняльний аналіз смисложиттєвих орієнтацій студентів різних напрямів професійної підготовки (гуманітарних та технічних). Встановлено, що смисложиттєві орієнтації мають певну специфіку в студентському віці, але статистично не відрізняються в залежності від напрямку професійної підготовки. Емпірично досліджено особливості розвитку особистісних цінностей в осіб студентського віку. Зроблено висновок про те, що найбільш значущими цінностями для студентів є цінності гуманності (любов, доброта, соціальний інтелект, готовність і вміння підтримувати доброзичливі стосунки з оточуючими) та трансцендентності (цінування красоти і видатних досягнень; вдячність, надія, гумор, духовність).

Published: February 2023

Розглянуто поняття антикризової стратегії. Проаналізовано класифікацію антикризових стратегій за основними ознаками: за стадією антикризового управління, залежно від характеру впливу кризи на діяльність підприємства, залежно від концепції стратегічного управління, залежно від критерію малобюджетності, залежно від прогнозу ситуації на ринку і можливостей самого підприємства, залежно від елементів маркетингу-мікс, залежно від конкурентної позиції та поведінки на ринку та залежно від виду кризи. Запропоновано модель вибору та розроблення антикризової стратегії, що враховує сучасну законодавчу базу, теоретичні основи стратегічного управління, та практику підприємств щодо здійснення заходів по виходу несприятливих ситуацій. Дана модель відображає взаємопов’язаний комплекс стратегічних і оперативних заходів, кожен з яких підпорядковується єдиній меті, цілям і завданням, пов’язаних з реалізацією антикризової політики підприємства, а її елементи можуть мати як захисний, так і наступальний характер. Встановлено, що при виборі стратегії на автотранспортному підприємстві необхідно передбачити локальні прийоми, механізм тактики її реалізації. Виділено три основні стратегії кризового управління: стратегія усунення небажаної конкуренції, стратегія попереджуючої атаки та стратегія відволікаючого маневру. На основі проаналізованих стратегій сформовано алгоритм вибору антикризової стратегії автотранспортним підприємством (АТП). Запропоновано методологічний підхід  до формування механізму стратегії на етапі виходу з кризи, що  являє собою логічну взаємоузгоджену систему стратегій всіх рівнів ієрархії, методологічне забезпечення та практичний інструментарій  її реалізації, які взаємопов’язані між собою. Запропонована методіка опробована на прикладі ПАТ «АТП-15339».

Clinical association study on the matrix metalloproteinase expression in the serum of patients with connective tissue disease complicated with interstitial lung disease
Authors: Chen Hong , Tang Jun , Liang Juhua , Huang Dan , Pan Chunfeng , Liu Sha , Du Xiuri , Tao Liju
Published: February 2023

Objectives: This study was implemented to reveal the expression and the clinical correlation of matrix metalloproteinases (MPSs) with connective tissue disease (CTD) complicated with interstitial lung disease (ILD).

Patients and methods: This clinical study was conducted with 260 patients (151 males, 109 females; mean age: 47.3±12.5 years; range, 29 to 67 years) between October 2019 and October 2020. Among the subjects, 100 were CTD patients (CTD group), 80 were CTD patients with ILD (CTD-ILD group) and 80 were healthy individuals (control group). The MMP-2, -3, -7, and -9 levels in the serum of the three groups were detected by enzyme-linked immunosorbent assay.

Results: Serum levels of MMP-3, -7, and -9 in the CTD-ILD group were higher, while the MMP-2 level was lower than those in the CTD group and the control group. The MMP-7 level in the serum of the CTD-ILD group was positively related to C-reactive protein, erythrocyte sedimentation rate, and rheumatoid factor and negatively correlated with immunoglobulin G and complement 3. The MMP-7 expression in the serum was positively correlated with forced expiratory volume in one second (FEV1%), FEV1/forced expiratory volume (FVC), and FVC in CTD-ILD patients. Pearson statistical analysis revealed that there was a significant positive correlation between the MMP-7 expression and the percentage of B cells in the serum of CTD-ILD patients.

Conclusion: Expressions of MMP-3, -7, and -9 are significantly increased in the serum of patients with CTD and related interstitial lung lesions, and the high expression of MMP-7 indicates dynamic lung lesions, which is possible to be used as a possible biomarker for early diagnosis and assessment of disease progression.
El ocio como práctica educativa en las familias. Perspectivas de los expertos.
Authors: Hernández Prados Mª Ángeles , Álvarez Muñoz José Santiago
Published: February 2023

Dentro de los estudios de ocio, el familiar es el más insuficientemente tratado. No estamos ante un ámbito, sino ante una modalidad concreta con características especificas que merece ser investigado como elemento pedagógico que está inerte en la vida familiar. El objetivo de este estudio fue evaluar la opinión de expertos en ocio y tiempo libre sobre las amenazas, oportunidades, fortalezas, debilidades, tipologías, agentes y beneficios del ocio familiar, así como los valores y capacidades que desarrolla. Se optó por un diseño mixto con una recogida de datos cualitativa mediante la entrevista a 18 expertos y una cuantificación mediante categorías de la información obtenida. Los expertos señalan como principales fortalezas y oportunidades del ocio familiar la comunicación y la cohesión, la conciliación y diferencias generacionales como debilidades y amenazas que lo obstaculizan, predominando las experiencias deportivas, domésticas y culturales promovidas por instituciones públicas, centros educativos y asociaciones. Igualmente, el respeto y la tolerancia son los valores más trabajados desde estas prácticas familiares y lo social, emocional y conductual resultan las capacidades principalmente fomentadas. Se concluye la necesidad de diseñar instrumentos a partir de las aportaciones de los expertos, que permitan indagar empíricamente estos aspectos del ocio familiar y establecer prácticas de investigación evaluativas al respecto.

Published: February 2023

Das subjektive Wohlbefinden ist ein relevanter Aspekt der psychischen Gesundheit und steht im Zusammenhang mit akademischem Erfolg. Dennoch liegen bislang wenige Erkenntnisse zum subjektiven Wohlbefinden internationaler Studierender in Deutschland vor. Vor diesem Hintergrund wurde anhand der Daten aus dem Projekt Studienerfolg und Studienabbruch bei Bildungsausländerinnen und -ausländern in Deutschland im Bachelor- und Masterstudium (SeSaBa) mittels diskontinuierlicher latenter Wachstumskurvenmodelle das subjektive Wohlbefinden internationaler Studienanfängerinnen und -anfänger in Deutschland über einen Zeitraum von drei Jahren untersucht. Die Ergebnisse zeigten keine substanzielle Veränderung der mittleren Ausprägung des subjektiven Wohlbefindens im Studienverlauf. Dennoch wurden Unterschiede zwischen Studentinnen und Studenten, zwischen Studierenden aus verschiedenen Herkunftsregionen sowie zwischen Bachelor- und Masterstudierenden identifiziert. Studierende, die im Studienverlauf einen Studienabbruch berichteten, wiesen schon zu Studienbeginn ein geringeres Wohlbefinden auf.
Metamorphic Evolution of the Garnet Amphibolite Schist from Mawat Ophiolite, Kurdistan Region, Northeast Iraq: Geochemistry, Mineral Chemistry and Thermodynamic Approach
Authors: Omer Danar , Mohammad Yousif , Yara Irfan
Published: February 2023

The garnet amphibolite schist is associated with the gabbroic unit of the Mawat ophiolite, Kurdistan region, Northeast Iraq, in the imbricated zone of the Zagros orogenic belt. Field observation, petrographic study, mineral chemistry, geochemical data, and thermodynamic modeling were used to demonstrate mineral identification, predict the observed stable mineral assemblages, and validate the protolith. The mineral assemblages of prograde are garnet (pyrope-almandine), chlorite (clinochlore), amphibole (grunerite), plagioclase (anorthite), iron oxides while the garnet (almandine-pyrope), chlorite (chamosite), amphibole (cummingtonite), and iron oxide represent retrograde assemblage. The relict pod of metagabbro in the center of the garnet amphibolite schist body consists mainly of plagioclase, amphibole, pyroxene, and iron oxide. Geochemical data reveals that the rock is depleted in SiO2 and CaO and enriched in refractory elements compared to the metagabbro. This may be attributed to the generation of silicic melts by partial melting and producing nearby plagiogranite. The rare earth elements (REE) patterns show that the garnet amphibolite schist is depleted in light rare earth elements (LREE) and gradually enriched in heavy rare earth elements (HREE). Thermodynamic modeling, field observation, combined with petrographic study constrains two metamorphic stages and one possible anticlockwise P-T-t path for garnet amphibolite schist, with increasing pressure and temperature of gabbroic rocks units of Mawat ophiolite. The rocks reached peak metamorphic conditions at more than 800 °C and 8–10 kbar, which partially melted the rock produced prograde resitite and melt. Later, the resitite rock retrograded to the lower stage at temperatures ranging from 620 to 650 °C and pressures ranging from 6.5 to 6.8 kbar. Anticlockwise P-T-t paths suggested based on geochemical and thermodynamic data for garnet amphibolite schist of the Mawat ophiolite. Moreover, the gabbro is considered to be the protolith of garnet amphibolite schist, which have been undergone eclogite facies metamorphism later overprinted by amphibolite facies.

Authors: Esmael Sarween , Seeyan Shwan
Published: February 2023

The chemical analysis of groundwater for any region is very important for water resources and estimating the suitability of this important natural resource. Sixty two groundwater samples were collected during two recharge periods in October 2021, which represent the minimum recharge period and May 2022 which represent the maximum recharge period. The physical analysis include electrical conductivity, pH, and temperature while the chemical analysis includes major cations and anions. A piper diagram was used to classify the groundwater water in the area to determine water type which all water samples are categorized as bicarbonate water type for both periods. To establish the appropriateness of groundwater as drinking water in the area, different standards were employed as standard of water use. All water samples in the study area are fresh water and of medium salinity water except one well which is high salinity water. The groundwater quality in the studied area is suitable for drinking because all parameters are under permissible limit except one well which have a high nitrate concentration. According to the Total Dissolved Solids the water is acceptable for irrigation and do not cause harmful effects on crops except two water samples that can be used and adversely affected crops that were susceptible to salt, and suitable according to SAR ratio and low sodium hazard. The aim of this study is to determine water quality and evaluate groundwater for different uses including drinking, agriculture and irrigation purposes.

Comprender lo que es un proyecto educativo implica identificar un problema, sus causas y consecuencias y a partir de ello planear un proceso para alcanzar el objetivo que lo solucione total o parcialmente. Este proceso implica desde la selección del problema, su tratamiento y la presentación del informe de resultados: concepción, planeamiento, formulación de acciones, implementación y evaluación. El aprendizaje colaborativo es la instancia de aprendizaje que se concreta mediante la participación de dos o más individuos en la búsqueda de información, o en la exploración tendiente a lograr una mejor comprensión o entendimiento compartido de un concepto, problema o situación. (scagnoli, 2005). Es así que en la materia de Electricidad y Electrónica Industrial que se imparte en la carrera de Ingeniería Industrial se ha utilizado todo lo referente al ámbito del aprendizaje colaborativo, para que todos los alumnos del grupo elaboraran el libro de texto del módulo, cumpliendo con el programa oficial de la carrera aprobado por el Tecnológico Nacional de México. En este orden de ideas, leidner y jarvenpaa (1995), señalan que el aprendizaje colaborativo, además de ayudar a desarrollar el pensamiento crítico en los estudiantes, también contribuye a mejorar las relaciones interpersonales, pues implica que cada uno de los miembros aprenda a escuchar, discernir y comunicar sus ideas u opiniones a los otros con un enfoque positivo y constructivista. Por otra parte, barab, thomas y merrill (2001), se refieren al aprendizaje colaborativo, como la construcción de significado que resulta de compartir experiencias personales. Estos autores insisten que los entornos virtuales ayudan a los modelos educativos a ser más participativos, y amplían las oportunidades de investigación, comunicación y distribución del conocimiento.

Background and objectives: Intravaginal practices are quite common among women worldwide and expose to bacterial vaginosis. The aim of our study is to evaluate the prevalence of intravaginal practices in women of childbearing age who came for consultation at the Gynaeco-Obstetric and Pediatric Hospital of Yaoundé and to determine its association with bacterial vaginosis. Methods:We conducted a prospective and cross-sectional study among 212 women from April 12 to July 30, 2021. Each participant was submitted to a questionnaire and was taken a vaginal swab. For the diagnosis of bacterial vaginosis, we made a flame-fixed slide smear and then stained by Gram's method. We classified the vaginal flora into four types according to Thomason and to make the diagnosis of bacterial vaginosis. Results:The prevalence of intravaginal practices was 54.7% among participants. The dominant type of intravaginal practices was scraping the vaginal walls with fingers (85.34%), followed by vaginal douching (6.03%). Women aged 26 to 33 were more adept at intravaginal practices (36.20%) followed by women aged 18 to 25 (34.48%) but the difference was not significant. Regarding the level of education, university-level women were more represented concerning the intravaginal practices (52.58%) followed by secondary school women (39.65%) but the difference observed was not significant. 38.79% and 1.72% of women performing intravaginal practices suffered from Gardnerella vaginalis and Mobiluncus infections respectively against 37.5% and 4.16% of Gardnerella vaginalis and Mobiluncus infections respectively in those who did not performe intravaginal practices; however, intravaginal practices was not statistically related to Gardnerella vaginalis, Mobiluncus and HIV infection (p=0.847;p=0.286, p=0.296) respectively). Conclusion: These intravaginal practices are common among women and were not statistically related to bacterial vaginosis flora or HIV infection. Women should be educated about maintaining their vaginal cavity to avoid vaginal infections.

The objectives of this study were to detect pre-heart failure based on NT-proBNP in subjects with hypertension and to identify the risk factors for pre-heart failure. Research methods: We conducted a cross -sectional study between August and December 2022. This study was included 526 subjects with hypertension aged from 35- to 64 years, who had no clinical symptoms of heart failure. Cardiovascular risk factors were detected by clinical examinations and laboratory test. Hypertension was defined as systolic BP ≥ 130 mm Hg, diastolic BP ≥ 80 mm Hg, and/or receiving treatment with anti-hypertensive agents. NT-pro BNP determination was performed on an immunoassay analyzer (Getein 1100). An elevated NT-pro BNP was defined as a NT-pro BNP ≥ 125pg/ml. Pre-heart failure was based on elevated NT-pro BNPlevel. Ethical statement Research ethical permission was obtained from the Biomedical Ethics Committee of Mongolian National University of Medical Sciences. Research results: In total, 526 hypertensive subjects s aged 35-64 year enrolled in this study, of which, 243 (46.2%) were men and mean age was 52.5±7.7 years. The prevalence of pre-heart failure based on NT-pro BNP in women was non-significantly higher than in men(17.3% vs 14.0%, p= 0.297). The prevalence of pre-heart failure increased from 4.0% for men aged 35-44 years to 20.9% for men aged 55-64 years. Based on our logistic regression analysis, the likelihood of elevated NT-pro BNP in hypertensive subjects was independently associated with age(OR 2.18, 95%CI 1.51-3.14) and poor blood pressure control(OR 2.41, 95%CI 1.29-4.50). Conclusion: The present study showed that the overall prevalence of pre-heart failure in hypertensive subjects was 15.8% and increased with age. The poor blood pressure control and ageing were significant risk factors in the development pre-heart failure in subjects with hypertension.

Authors: Moore Dr Keith
Published: February 2023

The experiences of two schoolmasters in the small isolated Western Port Bay fishing community of Hastings last century are relevant for today's practising teachers. Like present day teachers, they lacked the independence that could only be acquired by wealth, but were afforded a degree of status locally through their positions. Moreover, their successes and disappointments were largely dependent upon the opinions and evaluations of others. The first head teacher was a stately old gentleman, but he was unable to command respect from some parents and his authority was tested. His successor was young, confident and outgoing. Within a short time he had transformed the school. Under him, it occupied a prominent cultural and social position in the village.
