Authors: A Pavanaganga , Anand Kondaguli Namrata
Published: August 2022

Introduction: Heavy menstrual bleeding (HMB) is dened as excessive menstrual blood loss which interferes with a woman's physical, social,
emotional and material quality of life. In India, 16% of the women aged between 15 and 44 are diagnosed with HMB. HMB has signicant effects
on personal, social, family, and work life of women and thereby reduces their quality of life
Aim And Methods: In this study, we aim to identify menstruation characteristics of the women and the effects of HMB on women's quality of life.
The participants are 150 volunteer women who were not pregnant or had menopause at the time the study was conducted and who consulted to the
Department of Gynecology and Obstetrics at a Rajarajeswari Medical College and Hospital, Bengaluru between November 2020 and January
2021. The patients who had HMB complaint were included in the case group (฀ = 75) while the relatives of the participants who did not have any
specic health problems composed the control group (฀ =75 ).
Results: Mean age of the participants in the case group was 45.5 year (p<0.05) . 23.9% women had HMB >3years , frequent cycles noted with
average length of cycle being 22.79 days and 53.3% being diagnosed with myoma . We evaluated the participants' quality of life and found that
HMB group members were affected more signicantly in all subscales of the SF-36 scale (physical functioning, pain, general health, vitality, social
role functioning, emotional role functioning, and mental health) when compared to the women in the control group and was found to be statistically
signicant with p < 0.05.
Conclusion: HMB has negative effects on women's quality of life. Therefore, quality of life of the women with HMB complaint should be
investigated and effective approaches should be designed.

Authors: Agrawal Preeti , Pandey Ashish , Pandey Megha , Monteiro Rashmi
Published: August 2022

Breast ultrasound is a primary diagnostic modality for evaluating suspected breast lesions. Histopathological examination of trucut biopsies helps in accurate typing and grading the tumor. In the present study we compared histopathological ndings of trucut breast biopsies with BIRADS score. It was a retrospective, 3 years study with 183 cases that had under gone ultrasound examination and trucut biopsy for histopathological examination. Among 183 cases, 8 were inconclusive, 93 were benign and 82 were malignant. In 183 cases, 62 cases were classied as BIRADS-II, 24 cases as BIRADS-III, 66 cases as BIRADS IV and 31 cases as BIRADS V. Sensitivity calculated was 98.78%, specicity was 86.02%, positive predictive value was 86.17% and negative predictive value was 98.77%. The disease prevalence was 46.86% and accuracy was 92%. P value was statistically signicant. Therefore, we conclude that BIRADS score is non-invasive and a useful test for evaluating breast lesions preoperatively. However, we cannot rely on BIRADS score in cases of sampling error, nature of the lesion or unusual radiological presentation that may lead to interpretation error and thus histopathology will be considered as gold standard in diagnosis of breast lumps.

Background: Ultrasonography remains the most powerful investigation till now to detect cholelithiasis because of a high sensitivity and
practically no side effects involved.
Method: This prospective study comprised of 100 patients reporting to the out -patient department of the Department of Surgery of Government
Medical College, Kathua between January 2022 to May 2022. These patients were diagnosed with cholelithiasis using USG and underwent surgery
for the same. The USG ndings were compared to the intraoperative ndings and conclusions were drawn. The informed consent for the use of their
data for the study was taken. The aim of the study was to nd the correlation between the ultrasonographic ndings and the intra-operative nds in
cholelithiasis.
Results: Ultrasound was shown having a positive predictive value of 94% for detecting cholelithiasis and the sensitivity of the USG for various
characteristics was found to be 7.69%, 79.31% and 62.79% for predicting hydrops, wall thickness and acute cholecystitis respectively.
Conclusion: The study concluded that ultrasonography is one of the best investigations to detect the presence and absence of the stones, with being
a fairly reliant investigation to measure the wall thickness and advanced stages of acute cholecystitis but being a poor investigation for detecting
hydrops.

Published: August 2022

Background And Aims: Hypotension is commonly associated side effect with Subarachnoid block (SAB) and it is widely used technique for
parturients undergoing lower segment caesarean section (LSCS). Hypotension is detrimental to both mother and baby so prophylactic measures are
essential to prevent it. So this study was conducted to use perfusion index as a predictive non-invasive measure of hypotension in parturients posted
for LSCS under SAB.
Materials And Methods: After obtaining written and informed consent, this prospective, double blind, observational study was carried out in 100
term pregnant females aged 20-40 years and were devided in two groups (50 in each) based on baseline PI, PI values ≤3.5 were in Group I and PI
values >3.5 in Group II. All parturients were given inj. bupivacaine 0.5% Heavy 2 ml (10 mg) in SAB. Incidence of hypotension and other
parameters, requirement of rescue drug and uids were recorded.
Results: In Group I (PI≤3.5) incidence of hypotension (8 vs 40, P=0.00), requirement of rescue drug (mephentermine) per parturient (1.92±4.92 vs
8.4±5.6, P=0.00) and Fluid requirement (ml) per parturient (1243.20±115.24 vs 1381.60±110.79, P=0.00) were signicantly less as compared to
Group II (PI>3.5). (p<0.05)
Conclusion: Parturients with PI>3.5 are at higher risk of developing hypotension after subarachnoid block and requirement of vasopressors and
uid is more as compared to those parturients with PI≤3.5.

Published: August 2022

Background: Despite advances in tyrosine kinase inhibitor (TKI) therapy for chronic myeloid leukemia in chronic phase (CML-CP), a sizeable proportion of patients with CML-CP remains refractory or intolerant to these agents.

Objectives: Treatment patterns, healthcare resource utilization (HRU), and costs were evaluated among patients with CML who received third or later lines of therapy (3L+), a clinical population that has not been previously well-studied, with unmet treatment needs as TKI therapy has repeatedly failed.

Methods: Adult patients with CML who received 3L+ were identified in the IBM® MarketScan® Databases (January 1, 2001–June 30, 2019) and the SEER-Medicare–linked database (January 1, 2006–December 31, 2016). Treatment patterns were observed from CML diagnosis. HRU and direct healthcare costs (payer’s perspective, 2019 USD) were measured in a 3L+ setting.

Results: Among 296 commercially insured patients with 3L+ (median age, 58.5 years; female, 49.7%), the median duration of first-line (1L), second-line (2L), and 3L therapy was 8.5, 4.2, and 8.3 months, respectively. The annual incidence rate during 3L+ was 3.4 for inpatient days, 30.8 for days with outpatient services, and 1.2 for emergency department visits. Mean per-patient-per-month (PPPM) total healthcare costs (pharmacy + medical costs) were $18 784 in 3L+, $15 206 in 3L, and $19 546 in 4L, with inpatient costs driving most of the difference between 3L and 4L (mean [3L] = $2528 PPPM, mean [4L] = $6847 PPPM). Among 53 Medicare-insured patients with 3L+ (median age, 72.0 years; female, 39.6%), the median duration of 1L, 2L, and 3L therapy was 9.7, 5.0, and 7.0 months, respectively. During 3L+, the annual incidence rate was 10.3 for inpatient days, 61.9 for days with outpatient services, and 1.5 for emergency department visits. Mean PPPM total healthcare costs were $14 311 in 3L+, $15 100 in 3L, and $16 062 in 4L.

Discussion: Patients with CML receiving 3L+ rapidly cycled through multiple lines. Costs increased from 3L to 4L; in commercially insured patients, inpatient costs were responsible for most of the cost increase between 3L and 4L, underlying these patients’ continued need for care.

Conclusions: These findings support the need for better treatment options in patients with CML undergoing later lines of therapy.

Published: August 2022

In 1969, the legal terminology revision project was launched for localization, and the scope of the project has been expanded to Japanese terms and sentence components since 2006. Based on these efforts, the “Easy-to-Understand Law” examination system was formalized in 2007.
The aspect of the revision can be considered diachronically by comparing the changes in the past versions of the . In particular, it is possible to capture the recent trend of terminology maintenance through analyzing 50 Japanese terms selected in 2020. Also, it is necessary to be more careful in selecting the terminology to prevent confusion under the situation of frequent law amendment.
As a result of reviewing the terminology maintenance process, it is concluded that the revision of Japanese legal terminology led to the development of democracy from the representative political ideology of breaking away from Japan's influence.

In a company or organization archives play an important role in supporting the activities carried out. Archives are documents that are stored to be reused when needed, therefore if the archived documents are not done properly it will hinder the process of further activities. At the Lawe Bulan sub-district office there are problems with the archive process which is still done conventionally. This raises several obstacles, such as the document search process which takes a long time, and over time the increasing number of archive documents makes the need for hardcopy document storage greater and there will be a risk of damage or loss of documents. Based on this, the authors offer a solution using a web-based data archive system with sequential search method. Sequential search method is an algorithm used to search for random or non-sequential data by tracing the array from beginning to end. This will certainly simplify the process of searching for archival data and simplify archival activities compared to using conventional archive systems.

Hierarchical Bi2WO6/TiO2-nanotube composites derived from natural cellulose for visible-light photocatalytic treatment of pollutants
Authors: Lin Zehao , Yang Zhan , Huang Jianguo
Published: August 2022

A series of Bi2WO6/TiO2-nanotube (Bi2WO6/TiO2-NT) heterostructured composites were prepared by utilizing natural cellulose (e.g., laboratory filter paper) as the structural template. The obtained nanoarchitectonics, namely Bi2WO6/TiO2-NT nanocomposites, displayed three-dimensionally interwoven structures which replicated the initial cellulose template. The composite Bi2WO6/TiO2-NT nanotubes were formed by TiO2 nanotubes that uniformly anchored with Bi2WO6 nanoparticles of various densities on the surface. The composites exhibited improved photocatalytic activities toward the reduction of Cr(VI) and degradation of rhodamine B under visible light (λ > 420 nm), which were attributed to the uniform anchoring of Bi2WO6 nanoparticles on TiO2 nanotubes, as well as strong mutual effects and well-proportioned formation of heterostructures in between the Bi2WO6 and TiO2 phases. These improvements arose from the cellulose-derived unique structures, leading to an enhanced absorption of visible light together with an accelerated separation and transfer of the photogenerated electron–hole pairs of the nanocomposites, which resulted in increased effective amounts of photogenerated carriers for the photocatalytic reactions. It was demonstrated that the photoinduced electrons dominated the photocatalytic reduction of Cr(VI), while hydroxyl radicals and reactive holes contributed to the photocatalytic degradation of rhodamine B.

Published: August 2022

Clean air is an essential human need. It is therefore not surprising that the WHO global health observatory estimated that in 2012, seven million deaths were caused by air pollution; with ambient air pollution contributing to 3.7 million deaths while household air pollution was responsible for 4.3 million deaths, and 7.7% of the global mortality. Africa is not left out in this epidemy. A review of literature on indoor air pollution and its contributory factors reveals that majority of the indoor pollutants come from construction material residues, indoor furnishings and finishing as well as lifestyle of the occupants of the buildings. The study carried out case studies on selected condominiums in Lagos to identify specific contributory factors to indoor air pollution and its effect on the building occupants. The research concludes by recommending that indoor air quality could be improved by introducing ‘green’ practices such as building with renewable construction materials, passive design, natural ventilation as well as healthy indoor plants to purify indoor air.

Published: August 2022

In order to valorize Algerian medicinal plants, this work aims to characterize quantitatively and qualitatively Artemisia campestris L. fractions, a medicinal plant from the Aures-Algeria area, and investigate its biological activities in vitro. During preliminary phytochemical screening, flavonoids, saponins, tannins, alkaloids, reducing compounds, and coumarins were discovered. Total polyphenols and flavonoids are greater in the n-butanolic fraction than in ethyl acetate and petroleum ether. The resulting antioxidant capability was assessed in vitro using three methods: DPPH free radical scavenging, hydrogen peroxide trapping, and iron reduction. The n-butanolic extract suppresses DPPH oxidation with an IC50 of 2.239±0.32mg/ml, which is comparable to that of standard (1.824±0.97mg/ml). Despite the fact that similar findings were seen in the neutralization of hydrogen peroxide and the iron chelating activity, The anti-inflammatory action was proven in vitro by inhibiting protein denaturation and increasing HRBC membrane stability (Human Red Blood Cells). The n-butanolic fraction was more effective than diclofenac in preventing BSA degradation. It also inhibited membrane hemolysis in human erythrocytes by up to 83%. Activated partial thromboplastin and prothrombin times were used to analyze extrinsic and intrinsic coagulation pathways in A. campestris in order to determine its anticoagulant activity. The n-butanol fraction had the greatest impact on PT and aPTT lengthening, with 75.2s and 351s at 3 mg/ml concentration, respectively. The n-butanolic fraction of the A. campestris aerial part exhibited antioxidant, anti-inflammatory, and anticoagulant activities. As a result, it may be a viable natural resource for mitigating the impact of stress, which causes inflammatory and cardiovascular disorders.

Published: August 2022

Oreochromis niloticus also called “chicken of aquaculture” is a fresh and brackish water fish recognizable among all other tilapias by continuous black stripes on the caudal fin. Morphometric characters of Tilapias were reported in Egypt, Turkey, Nigeria, Sri Lanka. In Algeria, studies on tilapia have treated the species Tilapia zillii, its morphology (Guezi et al. unpublished study) and its reproduction (Guezi et al, 2021). The Biometry of the nil tilapia Oreochromis niloticus of the south westof Algeria was studied from December 2020 to November 2022. A total of 220 individuals, whose total length varied between 3 and 21 cm and weight between 22.9 and 289.7 g, were examined. The percentage of the different morphological measurement in relation to the total length of the fish, the regression equation and the length weight relationship was calculated. Six (6) characters showed a positive allometry, seven (7) characters showed a negative one, while only the height of the caudal peduncle showed an isometry. The length weight relationship was expressed as: LogW = 2.458 Log TL – 1.061. This study presents the first results of the morphometry of O. niloticus in the south-west of Algeria, and must be completed by studies on age and reproduction.

Published: August 2022

In the last decades, the use of essential oils have been increased significantly to affect various aspects of human daily life (cosmetics, pharmacy,pesticide and food industry). The present work aims to study the chemical composition and antioxidant activity of essential oils of Juniperus oxycedrus local (Mostaganem Algeria) extracted by hydrodistillation and steam distillation. The comparative study has permitted to highlight the influence of various parameters on the yield of essential oils (drying, extraction time). Forty components were identified. The characterisation by (GC-MS) showed that the extraction by hydrodistillation gave a better result which was characterised by the presence of α-pinene (37.163 %), sabinene (12.829 %), and limonene (5.795 %) as main chemical constituents. The method of extraction showed that there was a significant influence on the composition of the essential oil. The essential oil of Juniperus oxycedrus showed a strong antioxidant activity. The activity of the oils obtained by hydrodistillation was higher than that obtained by steam entrainment (IC50 = 120 mg ml−1 and IC50 = 160 mg ml−1) with DPPH and β-carotene bleaching tests, respectively. Essential oils of J. oxycedrus could therefore represent good component to be used as an antioxidant agent.

Published: August 2022

Proteolytic enzymes represent one of the largest groups of industrial enzymes. Fungal proteases have been used for the large-scale production of industrial enzymes. The optimization of enzyme production is a very important objective, where the aim is to further improve the production process. Therefore, the application of an experimental statistical method is essential. In this study, the production of the enzyme protease was carried out by fermentation of a mold (Aspergillus niger) using two media, one based on wheat bran and the other based on peas chick. The optimization of the synthesis of the enzyme was carried out using a statistical method of experimental planning based on the Plackett and Burman matrices. The variables used are the 3 production factors temperature, pH, and substrate concentration. The results were modeled according to multiple linear regression. The results obtained revealed that the strain A.niger gave an excellent activity reaching 740 IU for the wheat bran medium and 194.54 IU for the chickpea medium. The study of pH optima and incubation temperature has shown that the protease produced by A. niger has an optimum pH equal to 6 and an optimum temperature of 40°C for wheat bran medium and has an optimum pH equal to 5 and an optimum temperature of 30°C for chickpeas. The results obtained from the experimental designs of Plackett and Burman proved to be ideal for the selection of factors influencing protease production.
Evaluation of Plant Growth-Promoting Yeasts and Their Effect on Chickpea Plant Growth

Published: August 2022

Yeasts play a significant role in a wide range of fields, and the fascination they arouse stems from their incredible diversity in natural habitats. Among these habitats we focused on the soil of a unique biotope (oasis) in the Algerian Sahara, where yeasts have received little attention. For the first time, the distribution of yeasts, was determined depending on the plant and seasons. Their metabolic activity represented in the PGP effects, benefits the studied plant (chickpea) at the soil level involving the production of NH3, IAAs, the solubilization of inorganic phosphorus and zinc oxide, and even the micro-symbionts by the stimulation of nodulation. The isolated yeasts were also shown to possess PGP properties that largely exceed those of the reference strain Saccharomyces cerevisiae, with the strain RSZ1 of Kodamaea ohmeri having the best solubilization and production indices. When compared to the non-infected control and those inoculated with the reference strain S. cerevisiae, these characteristics enhanced the dry biomass yield of the examined plant by three to four or even six times. Another effect was nodulation, in which the number of nodules significantly increased compared to the control. Yeasts have a high-temperature tolerance limit of 43°C, posing a significant challenge in this biotope. This little-known role of yeasts, particularly in Algeria, is interesting, and can be used with other microorganisms as an alternative to hazardous chemical fertilizers and as bio-inputs in the improvement of healthy agricultural production, revegetation of degraded sites, and the establishment of life in these biotopes.

Nosocomial infections (NI) are contracted at the level of a treatment facility after less than 48 hours from admitting the patients initiating health problems all over the world. The objective of this study was to measure the incidence of NI, identify microorganisms, and recognize the main factors related to the acquisition of NI in the reanimation unit (RU) at the hospital of Constantine in Algeria. This study is a longitudinal prospective descriptive survey started from January 23 to April 29, 2019. Among 50 patients included in the survey, six were found nosocomial infected with an incidence of 12% and density incidence of 22.8 NI/1000 days. The average age of patients infected is 54.5 years with a net predominance of women. Several infections have been highlighted with converged percentages, 34% of nosocomial pneumonia (NP), 33% of nosocomial urinary infections (NUI) and 33% of nosocomial septicemia (NS). The long stay of patients in the unit is the risk factor of the acquisition of NI in the RU in which the duration of hospitalization was 20.83 days. The microorganisms responsible for these infections are mainly: Acinetobacter baumannii as multiresistant bacteria (MRB) with a frequency of 34%, 22% each of extended spectrum beta-lactamase bacteria (ESBLB); Escherichia coli and Enterococcus sp. Candida albicans was the only isolated yeast with a percentage of 22%.

Published: August 2022

Recently, the deteriorated soil areas are growing dramatically in Algeria. The application of microorganisms to these areas in order to restore them is extremely beneficial. Thus, the aim of this project was to use yeasts to exploit their metabolites to promote plant growth and stimulate their micro-symbionts. This little-studied role in yeasts, particularly in Algeria, is very interesting and can be exploited with other microorganisms in the revegetation of degraded sites. Various yeast strains have been isolated from legume soil since the plant used is a legume whose production is encountering many difficulties. Yeast strains were then selected to study their effect on micro-symbionts, namely rhizobia and mycorrhizae and their effect on plant growth by evaluating their growth, rate of mycorrhization and dry weight, respectively. The results obtained underlined a significant impact on the growth of rhizobia, particularly with Rhodotorula mucilaginosa LSF2, and on mycorrhization by improving its frequency and intensity where the best result was obtained with Debaryomyces hansenii LSF1. In addition to this indirect effect, a direct effect on the plant was revealed following the various inoculations conducted using the selected yeasts and the reference strain Saccharomyces cerevisiae, which were be able to increase the biomass of the plant. This finding is interesting because it not only clarifies the role of yeasts but also provides an opportunity for their application in different fields through simple or mixed inoculation with other biofertilizers.

In order to constrain the size of the optical continuum emission region in the dwarf Seyfert 1 galaxy NGC 4395 through reverberation mapping, we carried out high-cadence photometric monitoring in the griz filter bands on two consecutive nights in 2022 April using the four-channel MuSCAT3 camera on the Faulkes Telescope North at Haleakalā Observatory. Correlated variability across the griz bands is clearly detected, and the r-, i-, and z-band light curves show lags of

minutes with respect to the g band when measured using the full-duration light curves. When lags are measured for each night separately, the Night 2 data exhibit lower cross-correlation amplitudes and shorter lags than the Night 1 light curves. Using the full-duration lags, we find that the lag–wavelength relationship is consistent with the τ ∝ λ
4/3 dependence found for more luminous active galactic nuclei. Combining our results with continuum lags measured for other objects, the lag between g and z band scales with optical continuum luminosity as τ
gz ∝ L
0.56±0.05, similar to the scaling of broad-line region size with luminosity, reinforcing recent evidence that diffuse continuum emission from the broad-line region may contribute substantially to optical continuum variability and reverberation lags.
Analysis and control of Aedes Aegypti mosquitoes using sterile-insect techniques with Wolbachia
Authors: Chinnathambi Rajivganthi , Rihan Fathalla A.
Published: August 2022

Combining Sterile and Incompatible Insect techniques can significantly reduce mosquito populations and prevent the transmission of diseases between insects and humans. This paper describes impulsive differential equations for the control of a mosquito with Wolbachia. Several interesting conditions are created when sterile male mosquitoes are released impulsively, ensuring both open- and closed-loop control. To determine the wild mosquito population size in real-time, we propose an open-loop control system, which uses impulsive and constant releases of sterile male mosquitoes. A closed-loop control scheme is also being investigated, which specifies the release of sterile mosquitoes according to the size of the wild mosquito population. To eliminate or reduce a mosquito population below a certain threshold, the Sterile insect technique involves mass releases of sterile insects. Numerical simulations verify the theoretical results.
L'harmonie entre l'authenticité et la fiction dans un jeu sérieux
Authors: Narainen Stelene
Published: August 2022

L'élaboration d'un jeu sérieux nécessite un équilibre entre le contenu pédagogique à assimiler et l'aspect ludique bénéfique à l'apprentissage. En plus de cette dualité, le jeu doit apporter une version de la réalité parsemée d'éléments fictifs, de sorte à offrir un contexte à la fois réaliste et attractif. La réussite d'un jeu sérieux repose sur l'adaptation constante au public visé. Notre recherche porte sur les apports pédagogiques d'une telle approche ainsi que sur les limites qu'elle peut poser. Nous proposons un prototype de jeu sérieux destiné à un public de jeunes adultes et visant l’acquisition du français langue étrangère. Dans la continuité de sa conception, nous souhaitons démontrer les plus-values pédagogiques d’un tel produit tout en gardant en mémoire les éventuels problèmes que l’on peut rencontrer en jouant.

Published: August 2022

Association Rule Mining(ARM) is one of the most significant and active research areas in data mining. Recently, Whale Optimization Algorithm (WOA) has been successfully applied in the field of data mining, however, it easily falls into the local optimum. Therefore, an improved WOA based adaptive parameter strategy and Levy Flight mechanism (LWOA) is applied to mine association rules. Meanwhile, a hybrid strategy that blends two algorithms to balance the exploration and exploitation phases is put forward, that is, grey wolf optimization algorithm (GWO), artificial bee colony algorithm (ABC) and cuckoo search algorithm (CS) are devoted to improving the convergence of LWOA. The approach performs a global search and finds the association rules sets by modeling the rule mining task as a multi-objective problem that simultaneously meets support, confidence, lift, and certain factor, which is examined on multiple data sets. Experimental results verify that the proposed method has better mining performance compared to other algorithms involved in the paper.
A Hybrid Learning Framework for Imbalanced Classification
Authors: Jiang Eric P.
Published: August 2022

Class imbalance is a well-known and challenging algorithmic research topic among the machine learning community as traditional classifiers generally perform poorly on imbalanced problems, where data to be learned have skewed distributions between their classes. This paper presents a hybrid framework named PRUSBoost for learning imbalanced classification. It combines a selective data under-sampling procedure and a powerful boosting strategy to effectively enhance classification performance on imbalanced problems. Different from the simple random under sampling algorithm, this framework constructs the training data of the majority or negative class by using a newly developed partition based under sampling approach. Experiments on several datasets from different application domains that carry skewed class distributions have shown that the proposed framework provides a very competitive, consistent, and effective solution to imbalanced classification problems.

Authors: A. Hemlata
Published: August 2022

Conducting the exam in different shifts means the variation in the difficulty level of the different shifts of the exam. Various recruitment bodies adopt normalization process to solve this issue. This paper contains a detailed study of the normalization process carried out by the recruitment bodies. The study also includes the effect of normalization in the candidate's score and it depends on the difficulty level of the shift in which the candidate appears in the exam. This work can be further enhanced by comparing the different methods adopted by similar recruitment/selection organization and adopting the best, more appropriate approach to improve the system. This analysis will help in improving the evaluation system and make the system more robust and accurate. So that a more accurate merit list can be prepared and all the stakeholders can be reassured. It is very important to make the system transparent, so that the stakeholders have a clear understanding of the system and at the same time they should be aware of the advantages and disadvantages of the system.

Published: August 2022

The risk measurement of financial credit industry is an important research issue in the field of financial risk assessment. The design of financial credit risk measurement algorithm can help investors avoid greater risks and obtain higher returns, so as to promote the benign development of financial credit industry. Based on the combined deep learning algorithm, this paper studies the risk measurement of financial and credit industry, and proposes a fusion algorithm of deep auto-encoder (DAE) and Long Short-Term Memory (LSTM) network. The algorithm recombines the value of fixed features by using the unsupervised mechanism of DAE, and extracts non fixed features for measurement combined with the memory characteristics of LSTM network. The experimental results show that: compared with single generalized regression neural network and LSTM network, the average accuracy of DAE-LSTM algorithm is improved by about 6.49% and 3.25% respectively, which has a better application effect in credit risk measurement.

Published: August 2022

Background: Teachers are responsible for developing and enhancing communication skills amongst young learners. Unfortunately, the overly structured pedagogy which many teachers adopt inhibits the optimal development of oral communication skills. Hence, the researchers investigated ways of strengthening group-work play-based pedagogy to stimulate oral communication.Aim: This research aimed to find out (1) what prior knowledge, skills and classroom practice teachers have and how they demonstrate their competence in implementing group play-based pedagogy; and (2) how a professional development programme assists teachers to implement play-based group pedagogy to develop oral communication skills in young learners.Setting: The study took place in the Owerri Education Zone in the eastern part of Nigeria.Methods: The researchers implemented a participatory action research (PAR) design. Nine participants were purposively selected from a cohort of teachers who taught the 5–9-year age group. Teacher participants responded to the semistructured interviews and observational schedules used as tools for data collection. The researchers used inductive thematic data analysis techniques to make sense of the data. This was performed in three phases: sorting the data and organising them in data sets, after which the analysis process commenced.Results: Findings from the study showed that although the participants had a fair understanding of play-based pedagogy, they did not know how to operationalise their understanding of play-based pedagogy directed at oral communicationConclusion: The participants gained expert knowledge of play pedagogies that require children to increase oral language use in interaction with each other, using vocabulary and phrases introduced by the teacher as scaffolding for their communication.
