Authors: KOŞAR Gülten , AKBANA Yunus Emre , YAKAR Levent
Published: January 2022

Reading self-efficacy performs a fundamental role in gaining academic achievement in college education. Review of the related literature unveils that it needs to be enriched by conducting further research on college students’ reading self-efficacy. The paucity of investigations into college students’ reading self-efficacy could have a connection with the lack of a comprehensive reading self-efficacy scale targeting exclusively measuring it. For this reason, this study aims at developing and validating a reading self-efficacy scale which could be used to measure college students’ reading self-efficacy. The data was collected from three distinct groups consisting of a total of 430 students of the departments of English language teaching and English language and literature studying at state universities in Turkey. The findings obtained from exploratory factor analysis revealed that the scale had a unidimensional structure and the ones provided by confirmatory factor analysis confirmed the structure of the scale. The developed and validated 16-item reading self-efficacy scale could prompt the university teachers of reading to undertake studies with an eye to examining their students’ reading self-efficacy.

Authors: Li Penglin , Tao Ran , Huang Shuai , Wang Rong , Xu Chengguang
Published: January 2022

The mechanical characteristics of coral reef sandy soil is significantly different from the sand and clay soils. Currently, Terzaghi's bearing capacity equation is still commonly applied to evaluate the bearing capacity of coral reef, while the calculation result is not consistent with the actual condition. Based on a port project in east Africa, plate loading test of the coral reef sandy soil has been conducted and the P-S curves are obtained, and the bearing capacity values obtained from the plate loading test results are compared with the calculated results based on the Terzaghi’s bearing capacity equation. According to multiple linear regression and the optimal regression equation selected by the significance test, the modified Terzaghi foundation equation of bearing capacity in coral reef sandy soil area is proposed, and the modified Terzaghi foundation equation has important reference value for the calculating of the bearing capacity of the coral reef sandy soil foundations.
The enhancement of fault detection for rolling bearing via optimized VMD and TQWT based sparse code shrinkage
Authors: Yuan Xing , Zhang Huijie , Liu Hui
Published: January 2022

A typical vibration signal of fault bearing is composed of periodic repetitive transient impulses, multiple vibration disturbance and background noise. Variational mode decomposition (VMD) represents a potential tool for analyzing such signals. However, the reasonable selection of VMD algorithm parameters hinders its application in mechanical signal processing to a certain extent. According to the specific characteristics of rolling bearing fault signal, the composite dimensionless index is constructed as the objective function to ensure the optimal decomposition of VMD. To further enhance the fault characteristics, the tunable Q-factor wavelet transform (TQWT) along with sparse code shrinkage is proposed to denoise the modal components containing periodic impulses, which further highlights the impulses and improves the sparseness of fault signal. Simulation and experimental signal analysis verify the effectiveness and reliability of this method. The results show that the use of optimized VMD and TQWT based sparse code shrinkage dramatically sharpens the impulses from the mixed signal with noise interference and increases the sparseness to a level.

Published: January 2022

The multi-power coupling transmission system (MPCTS) is an electromechanical coupling system, which typically use two or more induction motors to provide its driving torque. It is used in various industrial applications, such as cutter header driving systems of tunnel boring machinery, and yaw systems of wind turbines. In practical engineering applications, the loads borne by the MPCTS are very complex, including both torque loads and non-torque loads. Its dynamic characteristics are affected by both the gear transmission system and the drive motors. For this study, an electromechanical coupling dynamic model of the MPCTS, coupled with a gear transmission system, induction motor, and non-torque load, was constructed to analyze its dynamic characteristics under a non-torque load condition. The results showed increased offsets from the gear vibration equilibrium position, as well as deterioration in system load-sharing characteristics from increases in non-torque load and rotational speed. However, the influence of the non-torque load was significantly greater than that of the rotational speed.
Determining rainwater harvesting potentials in municipalities by a semi-analytical method
Authors: Ulker Erman , Tasci Hadya
Published: January 2022

Due to increasing population, uncontrolled water consumption, and abnormal climatic conditions, the potential of usable water is running out. Water has become one of the most valuable resources for the countries; therefore, rainwater harvesting systems for water recovery gain importance to implement in buildings. Thus, authorities have begun to search for fast and accurate decision tools before taking any action. In the present study, a semi-analytical method for determining the rainwater harvesting potential of the given location is implemented in the Java programming language. Three major districts of Izmir, Turkey are chosen for the study site, namely Cigli, Bayrakli, and Karsiyaka. The result shows that implementing rainwater harvesting systems only in public buildings recovers less than 1% of the population's water needs. On the contrary, encouraging the free zones, which has large rooftop area such as airports and malls, for implementing and using rainwater increases the water recovery to 13% of that district's water needs. It is still a small portion of the public's water needs; therefore, spreading rainwater harvesting in the communities is necessary. It is believed that more accurate and user-friendly rainwater harvesting simulators would encourage the communities to harvest rainwater.

Published: January 2022

Safe sanitation service is vital to a healthy life and promoting well-being. However, information on the proportion of households' access to safely managed sanitation services and its determinants in urban resource-limited settings is particularly scarce in Ethiopia. This study aimed to determine households' access to a safely managed sanitation service and its associated factors in Jimma, Ethiopia. A cross-sectional study design was conducted on 782 households selected randomly. Household heads were interviewed using a structured questionnaire and facility conditions were assessed using an observation checklist. The proportion of households with access to sanitation services was presented in frequency and percentage. A binary logistic regression analysis was employed to determine the association between the explanatory and dependent variables. The study found that a significant proportion of households (87%) use unsafe sanitation services. The presence of a school-attending family member, a smaller family size, heads of households engaged in private work, wives engaged in employed work, a higher monthly income, and toilet age are all associated with access to safely managed sanitation. To ensure safe sanitation access in the setting, sanitation interventions should take into account household differences, prioritize sustainable sanitation technology options in newly built toilets, improve households' economic status, and expand job opportunities and education for mothers, which demands long-term policy interventions.
Simulating and predicting soil water dynamics using three models for the Taihu Lake region of China
Authors: Chen Can , Lv Qing , Tang Qian
Published: January 2022

Drought stress under a changing climate can significantly affect agricultural production. Simulation of soil water dynamics in field conditions becomes necessary to understand changes of soil water conditions to develop irrigation guidelines. In this study, three models including Auto-Regressive Integrated Moving Average (ARIMA), Back-Propagation Artificial Neural Network (BP-ANN), and Least Squares Support Vector Machine (LS-SVM) were used to simulate the soil water content in the 0–14 cm and 14–33 cm soil layers across the Taihu Lake region of China. Rainfall, evaporation, temperature, humidity and wind speed that affect soil water content changes were considered in the BP-ANN and LS-SVM, but not in ARIMA. The results showed that the variability of soil water content in the 0–14 cm soil layer was greater than that in 14–33 cm. Correlation coefficients (r) of soil water content between simulations and observations were highest (0.9827) using LS-SVM in the 14–33 cm soil layer, while they were the lowest (0.7019) using ARIMA in the 0–14 cm soil layer; but no significant difference in r values was observed between the two soil layers with the BP-ANN model. Compared with the other two models, the LS-SVM model seems to be more accurate for forecasting the dynamics of soil moisture. The results suggested that agro-climatic data can be used to predict the severity of soil drought stress and provide guidance for irrigation to increase crop production in the Taihu Lake region of China.
Novel scheme for synergistic purification of copper mine tailings and orthophosphate
Authors: Zhou Runjuan , Zhang Ming
Published: January 2022

Copper tailings (CTs) and orthophosphate are major environmental pollutants. CTs cause severe heavy metal pollution, and orthophosphate is one of the primary causes of water body eutrophication. This study aimed to alleviate heavy metal pollution by CTs and the eutrophication of water caused by orthophosphate. To this end, a 50 mg/L orthophosphate was used as a chemically active leaching solution and passed through a CT soil column. The tail water was then collected. Laboratory leaching tests showed that the thermally modified CTs effectively trapped orthophosphate, and the orthophosphate content in the leachate was 0.15 mg/L. After chemical washing, Cu2+, Cd2+, and Zn2+ were tested in the tail water, and the heavy metal ions in the tail water were removed using an advanced treatment technology. After treatment with 20.0 g/L water hyacinth biochar (WHBC), the removal rates (R%) of Cu2+, Cd2+, and Zn2+ were 99.48, 94.94, and 94.84%, respectively. These results demonstrated that this novel scheme for the synergistic purification of CTs and orthophosphate was feasible in the laboratory. This study provides new theoretical guidance and technical support for CT soil heavy metal remediation and water eutrophication treatment.
Cyclopentadienyl Titanium Derivatives in Organic Synthesis
Authors: Petasis Nicos A. , Hu Yong-Han
Published: February 2022

Among the numerous known compounds of titanium only relatively few have found wide applicability in organic synthesis. Prominent among these are some organotitanium compounds with one or two cyclopentadienyl substituents, which have found increasing use in recent years for a variety of synthetic transformations. Unlike many other transition
metals, the use of titanium is not limited only to catalytic systems, but it is often used in stoichiometric quantities, due to the high abundance, low cost and low intrinsic toxicity of this element.

This review focuses on the use of cyclopentadienyl titanium derivatives for the synthesis of titanium-free products. The reactions are classified according to the type of chemical transformation and illustrative examples are given for both stoichiometric and catalytic systems. Wherever applicable, asymmetric variants are also highlighted.

After a general introduction on the most synthetically useful classes of cyclopentadienyl titanium compounds and their preparation, the review continues with the various types of reductions, including the hydrogenation, hydrosilylation and hydrometallation of unsaturated derivatives, and several methods for dehalogenation and deoxygenation. This is followed by a discussion of titanium-mediated oxidations, including alkene epoxidation and ketone hydroxylation. Several reactions in which the titanium compounds serve as Lewis acids are then discussed, including aldol reactions and cycloadditions. A number of methods involving the formation of C-C bonds, such as addition to carbonyls, nitriles and alkynes are then reviewed. This is followed by a discussion of methods involving the formation of C=C bonds from carbonyls, including pertinent synthetic applications. Several types of titanium-mediated cyclizations are then discussed with an emphasis on intramolecular reductive coupling reactions. Finally, an overview of several types of polymerization processes is given with an emphasis on Ziegler-Natta, ring-opening metathesis polymerizations, silane polymerizations and miscellaneous other polymerizations mediated by cyclopentadienyl titanium compounds.

Overall, this review not only illustrates the high chemical diversity of titanium but it also demonstrates the unique reactivity exhibited by the cyclopentadienyl substituents.

Combinatorial chemistry and parallel array synthesis techniques are now used extensively in the drug discovery process. Although published literature has been dominated by solid phase chemistry approaches, the use of solution phase techniques has also been widely explored. This review considers the advantages and disadvantages of choosing solution phase approaches in the various stages of drug discovery and optimisation, and assesses the practical issues related to these approaches. The uses of standard solution chemistry, the related liquid phase approach, and of supported materials to enhance solution phase chemistry are all illustrated by a comprehensive review of the published literature over the past three years.
Self-Assembled Membranes and their Applications
Authors: Thipe B.
Published: February 2022

Self-assembled membranes have gained a lot of attention in the scientific community. They offer a simple and cheap way to form membranes that serves specific purposes like water filtration, drug delivery, anti-glare coatings, dielectrics, scaffold tissue engineering, etc. Polymers are the most popular choice for making self-assembled membranes, however there are other available options like proteins, small molecules, etc. Each new method/material offers certain advantages and disadvantages. Polymer membranes are strong and durable, but offer low porosity. Other materials like proteins degrade quickly. Hybrid materials are thus synthesized to combine the advantageous properties of materials and form self-assembled membranes. It is difficult to obtain membranes that are thin, sturdy and long lasting. New materials are being synthesized. However, materials that already exist can also serve well enough. A different perspective is needed to look into current materials and put them into good use. Self-assembled membranes offer a lot of potential uses and a lot of research is being pursued in this regard.

Published: January 2022

Market integration can show that no matter what changes occur in the consumer market, it will cause price changes in the producer market. However, price information that has not been properly channeled between consumer and producer markets makes asymmetrical trasnmission and unintegrated market. This study aims to analyze the level of price variation and market integration of red chili in Ciamis Regency. The coefficient of variation analysis is used to analyze the level of price variation and the Johansen cointegration approach with the Vector Autoregression (VAR) / Vector Error Correction Model (VECM) model to analyze market integration. The results showed that the price fluctuation of red chili at the producer and consumer level was high and unstable. The results of the analysis of market integration show that there is market integration between the producer market and the consumer market in the long run but in the short term, they adjust to each other in the long term.

Palm print recognition system using siamese network and transfer learning
Authors:   Systems and Computer Engineering Department, Faculty of Engineering, Al-Azhar University, Cairo, Egypt, et al. Fawzy
Published: January 2022

This paper proposes a palmprint authentication approach using a one-shot learning technique based on similarity instead of classification (used by most other proposals). The one-shot learning technique uses the siamese network architecture built on top of the pre-trained VGG16 to efficiently reduce the cost and time of training the siamese network. This technique allows the user registration using only one palmprint and then performs the authentication process by performing a siamese similarity measure instead of classification techniques. The proposed model achieved high accuracies scores of 97%, 96.7% for Tongji datasets, 92.3%, 91.9% for PolyU-IITD datasets, 90.9%, 88.3% for CASIA datasets and 95.5% for COEP dataset. These performances were measured based on the testing dataset for unseen persons while the siamese training dataset was applied to different persons. The proposed model uses the pre-trained part of VGG16 as a feature extraction part then feeds the generated feature vector into the Euclidean distance layer that is trained in conjunction with the sigmoid layer to output the final similarity decision. Compared to other models, this proposed model achieved a high average accuracy of 93.2% and 0.19 EER over the available four palm print datasets which is generalized over proposals. All codes are open-source and available online at https://github.com/ProjectsRebository/PalmPrint-recognition-using-Transfer-Learning.

Experimentally investigated the possibilities of controlling the instability that develops in the form of traveling azimuthal waves in the spherical Couette flow. It was found that the action on the traveling azimuthal waves of periodic modulation of the internal sphere rotation speed can lead to their suppression, when the modulation is switched-off, the instability in the form of traveling azimuthal waves is restored, including with a change in the wave number. It was found that it is possible to maintain a stable stationary flow for a long time after the end of modulation - at least 50 minutes, or 2000 revolutions of the inner sphere, which is four times longer than the transition time in the stationary flow.

Triage Accuracy of Symptom Checker Apps: 5-Year Follow-up Evaluation
Authors: Schmieding Malte L , Kopka Marvin , Schmidt Konrad , Schulz-Niethammer Sven , Balzer Felix , Feufel Markus A
Published: January 2022

Background

Symptom checkers are digital tools assisting laypersons in self-assessing the urgency and potential causes of their medical complaints. They are widely used but face concerns from both patients and health care professionals, especially regarding their accuracy. A 2015 landmark study substantiated these concerns using case vignettes to demonstrate that symptom checkers commonly err in their triage assessment.

Objective

This study aims to revisit the landmark index study to investigate whether and how symptom checkers’ capabilities have evolved since 2015 and how they currently compare with laypersons’ stand-alone triage appraisal.

Methods

In early 2020, we searched for smartphone and web-based applications providing triage advice. We evaluated these apps on the same 45 case vignettes as the index study. Using descriptive statistics, we compared our findings with those of the index study and with publicly available data on laypersons’ triage capability.

Results

We retrieved 22 symptom checkers providing triage advice. The median triage accuracy in 2020 (55.8%, IQR 15.1%) was close to that in 2015 (59.1%, IQR 15.5%). The apps in 2020 were less risk averse (odds 1.11:1, the ratio of overtriage errors to undertriage errors) than those in 2015 (odds 2.82:1), missing >40% of emergencies. Few apps outperformed laypersons in either deciding whether emergency care was required or whether self-care was sufficient. No apps outperformed the laypersons on both decisions.

Conclusions

Triage performance of symptom checkers has, on average, not improved over the course of 5 years. It decreased in 2 use cases (advice on when emergency care is required and when no health care is needed for the moment). However, triage capability varies widely within the sample of symptom checkers. Whether it is beneficial to seek advice from symptom checkers depends on the app chosen and on the specific question to be answered. Future research should develop resources (eg, case vignette repositories) to audit the capabilities of symptom checkers continuously and independently and provide guidance on when and to whom they should be recommended.
Treatments for Primary Delusional Infestation: Systematic Review
Authors: Lu Justin Di , Gotesman Ryan D , Varghese Shawn , Fleming Patrick , Lynde Charles W
Published: January 2022

Background

Delusional infestation, also known as Ekbom syndrome, is a rare delusional disorder characterized by the fixed belief that one is infested with parasites, worms, insects, or other organisms. Although delusional infestation is a psychiatric condition, patients often consult dermatologists with skin findings, and it is currently unclear what treatments are recommended for this disorder.

Objective

We aimed to systematically review and describe the treatment and management of patients presenting with primary delusional infestation.

Methods

A systematic search was conducted using Ovid on MEDLINE, Embase, PsycINFO, and the Cochrane Register of Clinical Trials. Relevant data, including treatment, dosage, response, adherence, and side effects, were extracted and analyzed.

Results

A total of 15 case series were included, comprising 280 patients (mean age 53.3 years, 65.4% female) with delusional infestation. Overall, aripiprazole had the highest complete remission rate at 79% (11/14), although this was limited to 14 patients. Among drug classes, selective serotonin reuptake inhibitors were the most effective with a 79% (11/14) complete remission rate and 43% (9/21) partial remission rate in patients with comorbid depression, anxiety, or trichotillomania. First-generation antipsychotics and second-generation antipsychotics had similar complete remission rates (56/103, 54.4% vs 56/117, 47.9%, respectively) and partial remission rates (36/103, 35% vs 41/117, 35%, respectively).

Conclusions

Due to the rarity of delusional infestation, we only found 15 case series. However, we found that first-generation antipsychotics appear to be similar in effectiveness to second-generation antipsychotics for the treatment of primary delusional infestation. Larger studies and randomized controlled trials are needed to evaluate the efficacy of pharmacological therapy for delusional infestation.

A Fault-Tolerant Honeycomb Memory
Authors: Gidney Craig , Newman Michael , Fowler Austin , Broughton Michael
Published: January 2022

Recently, Hastings & Haah introduced a quantum memory defined on the honeycomb lattice. Remarkably, this honeycomb code assembles weight-six parity checks using only two-local measurements. The sparse connectivity and two-local measurements are desirable features for certain hardware, while the weight-six parity checks enable robust performance in the circuit model.In this work, we quantify the robustness of logical qubits preserved by the honeycomb code using a correlated minimum-weight perfect-matching decoder. Using Monte Carlo sampling, we estimate the honeycomb code's threshold in different error models, and project how efficiently it can reach the "teraquop regime" where trillions of quantum logical operations can be executed reliably. We perform the same estimates for the rotated surface code, and find a threshold of 0.2%−0.3% for the honeycomb code compared to a threshold of 0.5%−0.7% for the surface code in a controlled-not circuit model. In a circuit model with native two-body measurements, the honeycomb code achieves a threshold of 1.5%<p<2.0%, where p is the collective error rate of the two-body measurement gate - including both measurement and correlated data depolarization error processes. With such gates at a physical error rate of 10−3, we project that the honeycomb code can reach the teraquop regime with only 600 physical qubits.

Published: February 2022

Várias mudanças ocorrem no período da adolescência. O adolescente tem que desenvolver habilidades sociais, que são comportamentos que compõem o repertório do indivíduo para responder às demandas sociais adequadamente. Ele também enfrenta situações que podem desencadear estresse, que é a reação do organismo para reestabelecer seu equilíbrio após passar por situação estressora. O objetivo deste estudo foi verificar a relação de habilidades sociais e estresse com as variáveis: sexo, idade, tipo de escola e série. Foram utilizados os testes psicológicos ESA (Escala de Stress para Adolescentes) e IHSA-Del-Prette (Inventário de Habilidades Sociais para Adolescentes). Conforme os resultados encontrados no presente estudo, pode-se concluir que há correlação entre estresse e as variáveis sexo, idade e tipo de escola frequentada, assim como também entre a emissão de habilidades sociais e o tipo de escola frequentada. A hipótese de que as alunas teriam mais habilidades sociais que os alunos não foi confirmada, assim como também não se confirmou que os homens têm mais dificuldades na emissão das respostas do que as mulheres.
Formação contínua de professores e a teoria histórico-cultural na educação infantil
Authors: Chaves Marta
Published: February 2022

Neste texto apresentamos trabalhos realizados sobre a formação contínua de professores da educação infantil junto às secretarias municipais de Educação em diferentes regiões do Estado do Paraná no período de 2002 a 2016. Testemunhamos os desafios cotidianos de equipes pedagógicas e professores e consideramos que um dos elementos que contribuem para a fragilidade do trabalho pedagógico ocorre em função da constituição da formação contínua de professores não ser de fato contínua, como propõe a legislação educacional. Estudos e trabalhos por nós desenvolvidos, em uma década e meia, centram-se nas elaborações clássicas e contemporâneas da Teoria Histórico-Cultural, que defende a possibilidade de máximo desenvolvimento intelectual e que permite reafirmar a necessidade de organização do ensino tendo por base as máximas elaborações humanas da ciência e da arte. Como resultado dos trabalhos, temos o êxito de alguns municípios, equipes pedagógicas e professores, profissionais que desenvolveram o sentimento de pertencimento e apropriação de riquezas humanas e reconhecem-se como protagonistas do processo histórico, possibilitando que as crianças, de igual modo, tornem-se participantes altivos de suas histórias individuais e coletivas.
Por uma clínica de(s) território no contexto do SUS
Authors: Amaral Mariane Marques Santos , Da Escóssia Liliana
Published: February 2022

O texto analisa caminhos possíveis para uma prática clínica no/de território, no contexto do Sistema Único de Saúde (SUS). A trajetória de trabalho como psicóloga de uma de suas autoras, de 2007 a 2015, em diferentes unidades do SUS, serviu de campo para uma cartografia, entendida como método de pesquisa-intervenção. Nesse contexto, acompanhamos processos de constituição de diferentes modos de pensar e de fazer clínica, a partir de registros de cenas do cotidiano de trabalho. Estas, uma vez revisitadas, compuseram uma narrativa cartográfica de experiências. A pesquisa foi pautada por algumas noções: de clínica, como catalisadora de encontros produtores de passagens e desvios, operada no “entre fronteiras”; de saúde, como processo de produção, realizado por meio de agenciamentos; de território, como espaço de vida e processo. Com a pesquisa, afirmamos ser possível construir uma prática clínica de “corpos agenciadores” que se faz “no” território de vida das pessoas, e “de” território, ao incorporar seus elementos e acompanhar o movimento de (des)construção de paisagens subjetivas, num plano coletivo e movente. Ao engajar-se com o plano de constituição da vida, onde ela acontece, esta clínica se faz política, posiciona-se frente aos regimes de sociabilidade postos, fortalecendo o que há de público no SUS.
Paulo Freire e a revolução política do pensamento decolonial
Authors: Giroux Henry Armand , Figueiredo Gustavo de Oliveira
Published: February 2022

Argumentamos nesse ensaio que a obra de Paulo Freire pode ser lida como um texto decolonial e que os educadores progressistas devem se engajar de forma radical na transgressão de fronteiras para reconstruir a obra de Freire na especificidade de seu contexto histórico e político. Isso significa destacar a problemática de uma política de colonização situada no privilégio e poder do Ocidente com o objetivo de discutir como a questão ideológica de tal posição pode propor uma leitura distorcida da obra de Freire. Ao mesmo tempo, destacamos que Freire torna-se um cruzador de fronteiras revolucionário engajado no diálogo produtivo com os autores de seu tempo, produzindo uma obra crítica em que as relações sociais dominantes, ideologias e as práticas que apagam a especificidade da voz dos povos colonizados possam ser desafiadas e superadas. Em sua luta em favor da liberdade, o autor torna a educação e a cultura elementos centrais para a política e propõe ideias capazes de romper com a tradição conservadora e de restaurar a esperança na capacidade dos seres humanos em transformar a realidade e reescrever a história.

Published: January 2022

In this paper, we present a new operational matrix of derivative of
Jacobi wavelets. Shifted Jacobi polynomials and their properties are
employed for deriving a procedure to forme this matrix. Then Jacobi
wavelets expansions along with this operational matrix are applied for
solving ordinary differentiel equations with non analytic solution. It
is shown that Jacobi wavelets are very efficient and suitable for
solving this kind of problem. Several numerical examples are given to
illustrate the efficiency and performane of the presented method.

The prevalence of adverse drug reactions, adverse drug effects, avoidable deaths, and other drug-related problems arising from multiple drug administration is a wake-up call to our medical practitioners and the world at large, hence prompt action is required to this effect. In this paper, a computerized web-based system called “Anti-Polypharmacy Module” (APM) is being proposed which is geared towards checking the menace of polypharmacy by highlighting its adverse effect and drug-drug interactions. The drug library which contains most of the required information will be used to accomplish this task. The application is designed to be a user-friendly one. The system methodology for this work is the System Development Life Cycle (SDLC). This system is implemented using Java-servlet (JSP), JQuery, and SQL as a collection of software development tools. It is also a web-based application hence HTML5 and CSS3 are carefully crafted together for maximum user-friendliness. Apache Maven and Tomcat 7 are deployed for the back-end server technology. For database query optimization, the basic rules are strictly followed as discussed in the methodology. Keywords: Polypharmacy, Paediatrician, Therapeutic, Morbidity, Mortality, Drug-bank Database

Published: January 2022

Research studies have shown that most young and inexperienced academic members in higher institutions all over the world especially in developing nations required assistance in developing their academic career and enhancing their teaching experiences through mentoring. However, academic mentoring has not been effective in many higher institutions of learning, especially those in the developing world, Nigeria not exempted. With quantitative and qualitative approaches, this study explored mentoring among teaching staff, looking at how both variables determine the academic competence of teaching staff in Lagos State Polytechnic, Ikorodu Lagos. A cross sectional survey of all the schools in Lagos State Polytechnic was carried-out with a sample size of 200. The sampling technique used is purposive sampling. The study used descriptive statistics which include tables, percentages, and graph while Chi-Square was used to analyze the formulated hypothesis. Questionnaire was used as the major research instrument. The data analyzed for this study was from 150 academic staff that their questionnaire were properly filled and submitted and out of this, Chief Lecturers, Principal Lecturers and Senior Lecturers constituted 95 (63%) respondents, who we referred to as Mentor, and others constituted 55(37%), who we referred to as Mentee. This study used theories on mentoring, leadership and career development that relate to the study. The paper focused on three main research questions: measuring the level of awareness, mentoring and competence and formation of mentoring among teaching staff of Lagos State Polytechnic, Ikorodu. Findings from this study showed that teaching staff in Lagos State Polytechnic are very much aware of academic mentoring, and they believed that academic mentoring were developed on the basis of familiarity in research interests. It was also discovered from the review of literature that, the unresponsive attitude of some junior teaching staff, the pressure of administrative duties, unavailability of formal mentor/mentee structures were identified barriers to good mentoring skills among mentors and mentees. Based on these findings, the paper recommended among others that the institution should develop staff through policies on mentoring in Lagos State Polytechnic systems, this will serve as an avenue to groom new generation of competent academic staff, who will build responsible future leaders Keywords: Academic mentoring, grooming, academic competence, teaching staff

The study examined the impact (COVID-19) pandemic on family owned business (FOBs) in Southwest Nigeria. This study targeted a total population of 23,228 SMEs (SMEDAN, 2017) adopted for FOBs because most SMEs are FOBs in Nigeria. A sample size of three hundred and seventy eight 378 respondents from the total population constitutes the sample size for questionnaire that was administered. The determination of sample size for the study was achieved using the Raosoft sample size estimator. Out of the 378 questionnaire being distributed, only 250 were filled and returned appropriately. The study adopted multistage sampling technique. The focus of the study was based on fast moving consumable goods (FMCGs) producers of essential goods. The collected data was scored, tabulated, coded, and analyzed using multiple linear regression analysis with the aid of SPSS 23.0., the result reveals that there is a moderate significant relationship between COVID-19 pandemic and FOBs performance, where product patronage (r = 0.534, P< 0.01); growth (r= 0.623, P< 0.01), and profitability (r = 0.228, P< 0.01). Therefore, the study accepted the alternative hypothesis that there is a significant relationship exist between COVID-19 pandemic and FOBs performance. The study recommended that government should strengthen the business related incentive packages and circulate the information noticeably, this is indispensable in volatile potential of the Covid-19 pandemic predicament; FOBs should identify critical business issues and develop recovery strategy such as business recovery plan (BRP) to enable them mitigates the impact of covid-19 on their businesses; and opportunities should always tap from every situation by businesses.
