To create a learning process that is fun, exciting and can improve learning outcomes, it is necessary to have an interesting learning change that is applying STAD cooperative learning models and quizzes. The results of the study in the first cycle, classical learning activities only reached 52.94%. This has not yet reached the expected learning process improvement of yaitu 75%. But in the learning process the group has reached 88% with a target of ? 75%. While learning outcomes only reached 66.47% while the target determined 100% completely reached nilai 75%. To improve the classical learning process in the second cycle each student is given a visual aid a number of flat shapes to be formed into a variety of combinations to make questions. In Cycle II there was an increase in the classical learning process to 65.88% because there were 3 students asking questions and 14 students taking notes, where in Cycle I there were no students asking and taking notes. The group learning process increased to 91.05%. While learning outcomes reached an average of 76.47%. In Cycle III, in addition to the display for each student, to be able to find the formula for building area based on the area of flat shape that has been mastered by students, it is also added by giving homework assignments in the form of exercises. This is due to the increasingly difficult competency to master. In cycle III an increase in classical learning process was quite high to 84.61%. This is due to the increasing number of students who ask questions as many as 10 students and record as many as 4 students. The group learning process increased to 97.61%. While the learning outcomes reached an average of 79.61% with 100% of students achieving a value of ? 75. Thus all the targets set had been achieved. Based on the results of the study it can be concluded that the STAD type cooperative learning model can encourage students to learn about the area of more enthusiasm, improve the learning process, and learning outcomes.

A Comprehensive Survey of Deep Learning Multisensor Fusion-based 3D Object Detection for Autonomous Driving: Methods, Challenges, Open Issues, and Future Directions
Authors: Alaba Simegnew
Published: August 2022

Autonomous driving requires accurate, robust, and fast decision-making perception systems to understand the driving environment. Object detection is critical in allowing the perception system to understand the environment. The perception systems, especially 2D object detection and classification, have succeeded because of the emergence of deep learning (DL) in computer vision (CV) applications. However, 2D object detection lacks depth information, which is crucial to understanding the driving environment. Therefore, 3D object detection is fundamental for the perception system of autonomous driving and robotics applications to estimate the objects’ location and understand the driving environment. The CV community has been giving much attention recently to 3D object detection because of the growth of DL models and the need to know accurate locations of objects.

However, 3D object detection is still challenging because of scale changes, the lack of 3D sensor information, and occlusions. Researchers have been using multiple sensors to solve these problems and further enhance the performance of the perception system. This survey presents the multisensor (camera, radar, and LiDAR) fusion-based 3D object detection methods. The fully autonomous vehicles need to be equipped with multiple sensors for robust and reliable driving. Camera, LiDAR, and radar sensors and their corresponding advantages and disadvantages are also presented. Then, relevant datasets are summarized, and state-of-the-art multisensor fusion-based methods are reviewed. Finally, challenges, open issues, and possible research directions are presented.
The Treatment of Wood (Lumber)-2% Copper Naphthenate in Kerosene a Treatment for Decay Fungi, Insects-Termites, Ants and Beetles
Authors: Sealy Earl A.
Published: August 2022

The major agents for wood decay are decay Fungi, Termites, Beetles and Ants. This article reviews the current methods for treating wood (lumber) which includes the use of heat treatment and chemicals. The chemicals procedures used to resist the agents of decay are mentioned. Each agent of decay is outlined as well as the best preventative measures to resist that agent of wood decay. Construction measures that would help prevent wood decay along with treatment plans are discussed. How each agent of decay causes the wood to rot is mentioned and its warning signs. These warning signs enable the treatment plan for each agent of decay. It is recommended that all lumber (wood) used in construction should be treated before use. There is recommendation for the discontinuation of some wood treatment chemicals because of their danger to humans and pets. 2% Copper Napthenate in Kerosene is highly recommended as a chemical combination that can be used to treat all agents of wood decay. This is important because some chemicals are specific to a particular agent of decay and in this regard more than one treatment is required to hinder the agents of wood decay. A treatment plan for the use of 2% Copper Napthenate in Kerosene is outlined and the use of a Modified Gedrian’s Bath is proposed to treat wood at the commercial level. Engineering dimensions and temperature range for the use of 2% Copper Napthenate in Kerosene using the modified Gedrian’s bath is explained. The dangers of using 2% Copper Napthenate in kerosene is explained but these dangers are superseded by the economics of its use and its broad spectrum against all agents of decay. It is noted the limitations of heat treatment.

Hyposmia is one of the cardinal symptoms of Parkinson’s disease (PD), with a considerably high prevalence rate in PD individuals. However, some individuals still retain normal olfactory function. Recent studies have shown that genetic factors may play a role in such a phenomenon. This study aimed to explore the potential genetic factors underlying the variation of olfactory function among PD individuals. Two hundred and three Han Chinese individuals with PD were recruited into this study. All the individuals underwent detailed clinical assessment conducted by experienced neurologists. High-throughput sequencing was performed to identify gene variants associated with PD. TAAR5, OR6C70, and GBA were included in the association analysis. In our study, 85 out of 203 individuals (41.9%) reported normal olfaction, and the other 118 (58.1%) reported hyposmia. Genotype and allele logistic regression models were applied to association analysis. We did not find any significant association of TAAR5 and OR6C70 with hyposmia. However, we found that GBA rs762488 was associated with increased hyposmia risk (P = 0.036, OR = 3.05, 95% CI = 1.08–8.63), while GBA rs1800438 was associated with decreased hyposmia risk (P = 0.032, OR = 0.47, 95% CI = 0.24–0.94). In conclusion, this study revealed the association of GBA with hyposmia, indicating the genetic involvement in PD hyposmia variation. However, we did not replicate previous results (TAAR5 and OR6C70) in this study. Further studies with larger sample sizes in different populations are warranted.

Pain is a subjective feeling; it is a sensation that every human being must have experienced all their life. Yet, its mechanism and the way to immune to it is still a question to be answered. This re- view presents the mechanism and correlation of pain and stress, their assessment and detection approach with medical devices and wearable sensors. Various physiological signals (i.e., heart activity, brain activity, muscle activity, electrodermal activity, respiratory, blood volume pulse, skin tempera- ture) and behavioral signals are organized for wearables sensors detection. By reviewing the wearable sensors used in the healthcare domain, we hope to find a way for wearable healthcare-monitoring system to be applied on pain and stress detection. Since pain leads to multiple consequences or symptoms such as muscle tension and depression that are stress related, there is a chance to find a new approach for chronic pain detection using daily life sensors or devices. Then by integrating modern computing techniques, there is a chance to handle pain and stress management issue.

Published: August 2022

The efficiency, temperature distribution, and temperature at the tip of straight rectangular, growing and decaying moving exponential fins are investigated in this article. The influence of internal heat generation, surface and surrounding temperatures, convection-conduction, Peclet number and radiation-conduction is studied numerically on the efficiency, temperature profile, and temperature at the tip of the fin. Differential transform method is used to investigate the problem. It is revealed that thermal and thermo-geometric characteristics have a significant impact on the performance, temperature distribution, and temperature of the fin's tip.The results show that the temperature distribution of decaying exponential and rectangular fins is approximately $ 15 $ and $ 7\% $ higher than growing exponential and rectangular fins respectively. It is estimated that the temperature distribution of the fin increases by approximately $ 6\% $ when the porosity parameter is increased from $ 0.1 $ to $ 0.5 $. It is also observed that the decay exponential fin has better efficiency compared to growing exponential fin which offers significant advantages in mechanical engineering.
Research on mobile traffic data augmentation methods based on SA-ACGAN-GN
Authors: Gong Xingyu , Jia Ling , Li Na
Published: August 2022

With the rapid development and application of the mobile Internet, it is necessary to analyze and classify mobile traffic to meet the needs of users. Due to the difficulty in collecting some application data, the mobile traffic data presents a long-tailed distribution, resulting in a decrease in classification accuracy. In addition, the original GAN is difficult to train, and it is prone to "mode collapse". Therefore, this paper introduces the self-attention mechanism and gradient normalization into the auxiliary classifier generative adversarial network to form SA-ACGAN-GN model to solve the long-tailed distribution and training stability problems of mobile traffic data. This method firstly converts the traffic into images; secondly, to improve the quality of the generated images, the self-attention mechanism is introduced into the ACGAN model to obtain the global geometric features of the images; finally, the gradient normalization strategy is added to SA-ACGAN to further improve the data augmentation effect and improve the training stability. It can be seen from the cross-validation experimental data that, on the basis of using the same classifier, the SA-ACGAN-GN algorithm proposed in this paper, compared with other comparison algorithms, has the best precision reaching 93.8%; after adding gradient normalization, during the training process of the model, the classification loss decreases rapidly and the loss curve fluctuates less, indicating that the method proposed in this paper can not only effectively improve the long-tail problem of the dataset, but also enhance the stability of the model training.
A double-blind pilot randomized controlled trial of topical tranexamic acid after sinus surgery
Authors: Kumar A.R. , Wood A.J.
Published: August 2022

Background: There has been limited study of topical tranexamic acid (TXA) in endoscopic sinus surgery (ESS). We report a pilot study, examining the effects of topical TXA with regards to recovery after ESS. Methods: A pilot double-blind randomized controlled trial was conducted in 30 patients undergoing comprehensive ESS. Patients received either topical TXA or normal saline (NS) for 60 minutes via cotton pledgets at the conclusion of ESS. Patients were followed-up for a duration of 3-months. Results: The mean (95% CI) reduction in 22-item Sino-Nasal Outcome Test (SNOT-22) score at 3 months was 39.5/110 (26.9, 52.0) for TXA and 33.4/110 (24.0, 42.9) for NS (p=0.42). The mean (SD) Modified Lund-Mackay Post-operative Endoscopic (MLMES) score at 3 months was 7.79/100 ±7.70 for TXA and 10.9/100 ±9.35 for NS (p=0.12). TXA had a mean (SD) bleeding score of 4.0 ± 2.33 on day 1 compared to 3.64 ± 2.76 in NS group when measured on a Likert scale (p = 0.89). The mean self-reported time to return to work was 4.67 ± 2.22 days for TXA and 6.87 ± 4.42 for NS (p=0.10). Zero cases of confirmed thromboembolism were seen. Conclusions: Although statistically non-significant differences were observed, data from this pilot study imply that there is merit in a larger study to further assess the effects of topical TXA following ESS. There may be a role for increasing the exposure to topical TXA via a different formulation.

Authors: Zechariah Wada Ojima , Bamidele Olawade David , Opeyemi Amusa Aminat , Oluwadamisi Moses Jedidah , Jessica Eteng Glory
Published: August 2022

Background: Gender-based violence (GBV) has been identified to be one of the ripple effects of the global pandemic. In countries like Nigeria, the situation is hypothesized to be worse because of widespread poverty and gender inequalities. 

Objective: To examine the exposure of females to GBV during the first 3 months of the COVID-19 lockdown.

Method: This cross-sectional study was conducted in a low-income community in Lagos. Semi-structured questionnaires were administered to 130 respondents selected via systematic random sampling.

Results: The mean age of the respondents was 26.89 ± 8.67 years. Majority worked informal jobs, while only 50% had attained beyond primary education. Within the period, the respondents had been subjected to sexual (54.6%), physical (52.3%), verbal assault (41.5%), and online sexual harassment (45.4%); of which only 30% reported to the police. Furthermore, respondents subjected to sexual (p=0.004) and physical assault (p=0.032) during the period earned significantly less money than other respondents.

Conclusion: The fact that over 1 out of every 2 females was subjected to at least one form of GBV within the short timeframe shows how unsafe girls and women in low-income communities are. This calls for proactive community-level interventions to curb the GBV menace.

Keywords: Gender-based violence; COVID-19; women; girls; assault.
Perspectives on HIV Self-Testing Among Key and Affected Populations in Kenya
Authors: R Sircar Neiloy , A Maleche Allan
Published: August 2022

Background: Kenya’s Key and Affected Populations (KAP) – men who have sex with men (MSM), female sex workers, people who inject drugs (PWID), and young women aged 18-24 – often experience stigma and discrimination in Kenyan health care settings due to their identity and/or behaviors, which can deter facility-based testing for HIV. Kenya has promoted self-testing as a means to reach these communities.

Objectives: To identify KAP perspectives on self-testing and place our findings within Kenya’s human rights and legal context.

Methods: We conducted 4 focus group discussions (FGD) and 16 in-depth interviews (IDI). One FGD was conducted with each of the following communities: MSM, female sex workers, PWID, and young women aged 18-24. 1-4 IDI were conducted with each KAP community, and 1-3 IDI were conducted with health professionals working on HIV care in each study site. The semi-structured question guideline included one question soliciting opinions on self-testing.

Results: KAP support self-testing in concept, however prevailing concerns among participants included access to pre- and posttest counseling services, as well as risk for harms (self-inflicted and otherwise) that might result from a positive result.

Conclusion: Kenya should ensure that human rights are promoted and respected through implementing rights-based policies and practices for HIV self-testing, including pre- and post-test counseling.

Published: August 2022

Objectiv: To analyze the determinants of the decision to incision interval in case of emergency caesarean section in Yaoundé’ hospitals

Methods: A prospective cross-sectional (affected / non-affected) study was conducted in four hospitals in Yaoundé between January and may 2017 after National Ethical Committee approval. The target population was women who benefited from emergency caesarean section during the study period. Crude Odds Ratio (OR) and adjusted odds ratio (AOR) with 95% Confidence Interval was used to appreciate the association between several characteristics and the risk for long decision-incision delay.

Results:The overall cases of 165 emergency caesarean section were analyzed. The prevalence of emergency caesarean section performed within 30 minutes was 20%. Social factors associated with long delay to perform the emergency Caesarean section (> 30 minutes) were the primary level of education [ AOR: 3.63(2.44-5.41)], unemployment status [AOR: 5.17(2.95-8.95)]; and the absence of a parent at admission [AOR: 2.2(1.23-3.94)]. Medical factors associated with long delay from decision to incision were: use of spinal anesthesia in opposition to general anesthesia [AOR: 3.86(2.59-5.73)]; delay of transfer from emergency and the late provision of the operation supplies [AOR: 4.18(2.90-6.03)].

Conclusion: Few women benefit from the surgical intervention within a maximum of 30 minutes. Support measures for women presenting the indications for emergency caesarean sections in hospitals are essential to improve the decision-incision delay of the caesarean section emergency.

Keywords: Determinant; Decision; Emergency; Caesarean Section.

Authors: E Otim Michael , Kasirye Omagino Elizabeth , Almarzouqi Amina , A Rahman Syed , D Asante Augustine
Published: August 2022

Background: Improving maternal and child health, one of the key UN Sustainable Development Goals (SDGs), is a major challenge in sub-Saharan Africa. Exclusive breast-feeding contributes significantly to child survival and development, but many mothers in Africa do not exclusively breastfeed their infants. This paper reports a study in Mulago hospital in Kampala. The study aims to identify factors influencing mothers’ choices of infant feeding practices.

Methods: Mixed methods were used. Respondents included 362 lactating mothers and health workers. Participants were who came for treatment were selected using simple random sampling. EpiInfor and SPSS were used for analysing the data and presented as descriptive study.

Results: Results indicate that socio-demographic factors including age and education level influence mothers’ ability and willingness to breastfeed exclusively for the first six months. Awareness about breast-feeding was mainly obtained from health centres, leaving mothers unable to attend these centres to miss out on vital information about exclusive breast-feeding. Around 43% of health workers were unaware of the country’s Young and Infant Feeding Policy Guidelines.

Conclusions: To increase the rate of exclusive breast-feeding in Uganda, it is important that community health is strengthened, and health workers are trained on national breast-feeding policies.

Keywords: Child Health; Mothers; Breastfeeding.

Authors: Bwanga Osward , Musoko Kayembe Raphael , Maimbo Sichone James
Published: August 2022

Background: There has been a demand for radiographers in Zambia to perform intravenous (IV) cannulation and administration of contrast media, a role which, traditionally, was radiologists’. This demand is due to a shortage of radiologists and an increase in demand for imaging examinations. This review aimed at synthesising relevant literature related to IV cannulation and administration of contrast media by radiographers to guide the training and practice in Zambia.

Methods: A structured literature search was conducted in three online databases (PubMed/MEDLINE, CINAHL, and ScienceDirect), radiography journals, and cited references to identify research studies on IV cannulation and administration of contrast media by radiographers.

Results: Seven studies were identified and included in this review. The findings are summarised under six themes: benefits and challenges, adoption of the extended role, infection control, safety and complications, medico-legal issues, and education and training. Our findings revealed that radiographer-led IV cannulation and administration of contrast media contribute positively to the management of imaging patients.

Conclusion: The themes identified in this review could provide a template of where to base the establishment of the training programme and local guidelines. Before extending the role of radiographers, the scope of practice should be extended, and accredited training programme and local guidelines should be put in place.

Keywords: Contrast media; intravenous cannulation; radiographer; radiologist; Zambia.

Published: August 2022

The study examined factors influencing adoption of NERICA rice production and post-harvest technologies by smallholder farmers in Magbema and Kaiyamba chiefdoms in Sierra Leone. The data were purposively obtained from 150 smallholder NERICA farmers through a multi-stage sampling procedure from NERICA farmers in both chiefdoms. A structured questionnaire was used to collect data, analyzed with the aid of percentage and logistic regression. Demographic and socioeconomic characteristics of the farmers significantly influenced the adoption of recommended NERICA production technologies. For the post-harvest technologies, the R2 of 0.26 suggests that only the socioeconomic characteristics of the farmers significantly influenced the adoption of the recommended NERICA post-harvest technologies. Contact with extension agents, promotion of a literacy drive to raise technological awareness among farmers, and timely input delivery to attract and sustain the farmers’ interest to adopt NERICA rice production and post-harvest technologies.

Data collection was by structured interviewer-administered questionnaire. Descriptive and  inferential statistics were done. Level of significance was set at p<5%.Results: More respondents in urban area 186 (46.0%) were willing to accept COVID-19 vaccine compared to rural respondents 90 (22.7%) (p<0.001). Acceptance that COVID-19 is real (AOR=2.98; 95%CI=1.61-5.51 p<0.001) versus (AOR=2.17; 95CI=1.06- 4.44 p=0.035) predicted acceptability in both  urban and rural areas, respectively. In urban area, being a male (AOR=1.58; 95%CI=1.02-2.44 p=0.041) while in rural area, completion of  immunization (AOR=3.47; 95%CI=1.79-6.72 p<0.001) and fair perceived risk of contracting COVID-19 (AOR=3.05; 95CI:1.55-6.01 p= 0.001) were predictors of acceptability.Conclusion: The study showed there was overall poor acceptability of COVID-19 vaccine among urban and rural residents. Urban residents were  more likely to accept the vaccines compared to rural residents. Therefore, government should do more in terms of health education and promotion  for a right attitude to COVID-19 vaccination.

Purpose: To synthesize chloro-pyrazolines (A–D), determine their antimalarial activity against Plasmodium falciparum strain 3D7 in vitro, and understand the interaction between falcipain-2 active sites and synthesized compounds by molecular docking simulation.Methods: Chloro-pyrazolines (A–D) were synthesized via cyclo-condensation of 4-chloro chalcone derivatives using several types of hydrazines, i.e., formylhydrazine, benzoylhydrazine, phenylhydrazine and chlorophenylhydrazine. The compounds were analyzed and subjected to antimalarial assay against P. falciparum 3D7. Molecular docking was performed using AutoDock Tools and AutoDock Vina, while each docked compound was visualized using Discovery Studio Visualizer.Results: Pyrazolines A–D yield was 87.09, 61.71, 50.24 and 57.64 %, respectively. Antimalarial assay showed half-maximal inhibitory concentration (IC50) values of 16.46 and 5.55 μM for pyrazoline A and B, respectively, and ≥ 100 μM for pyrazoline C and D. Molecular docking study revealed that pyrazolines A–D had good interaction with the active site of falcipain-2 receptor.Conclusion: A series of N-substituted chloro-pyrazolines has successfully been synthesized with moderate yield. Pyrazoline B has the highest antimalarial activity against P. falciparum 3D7 with IC50 of 5.55 μM. This finding is supported by molecular docking and indicates that the benzoyl substituent increases the antimalarial activity of pyrazoline B. Pyrazoline B has potentials for clinical application as an antimalaria agent.
Short-term and long-term outcomes of zirconium dioxidebased dental restorations, and it effects on masticatory function
Authors: Peng Guodong , Yan Hui
Published: August 2022

Purpose: To investigate the short- and long-term outcomes of zirconium dioxide-based restorations (ZDBR), and changes in masticatory function (MF).Methods: One hundred and two (102) patients who received restorative dentistry procedures were divided into two groups using random number method: control group (CG, n = 52, alloy-based restorations) and study group (SG, n = 50, zirconium dioxide restorations). Treatment efficacy, quality, levels of IL-8 and IL-6 in gingival sulcus fluid, and satisfaction scores were compared.Results: The SG showed better outcomes and restoration quality than CG. After restoration, SG showed greater decrease in IL-8 and IL-6 levels than CG (p < 0.05), while IL-8 and IL-6 levels were higher in SG and CG than those before restoration (p < 0.05). After 1 and 6 months of restoration, SG showed increased dental appearance satisfaction and a higher success rate than CG (p < 0.05). Occlusal force and MF were significantly improved in both groups (p < 0.05). Gingival index, bleeding index, plaque index, and tooth looseness after restoration significantly improved in both groups, but were lower in SG than in CG (p < 0.05).Conclusion: In oral restorations, ZDBR is more effective in terms of short-term and long-term outcomes. Patients' occlusal force and MF are better restored, and patients' quality of life is also significantly improved. Therefore, ZDBR in oral restorations is feasible but further clinical trials are required.

Authors: Lu Tingting , Zhang Qiurong , Wu Xiao , Liu Senjun
Published: August 2022

Purpose: To determine the role and mechanisms of Krüppel-like transcription factor 8 (KLF8) in acute myeloid leukemia (AML).Methods: The transcriptional and translational levels of KLF8 in AML cell lines were determined by quantitative real time-polymerase chain reaction (qRT-PCR) and western blotting. Two RNAs targeting KLF8 were transfected into KG-1 and HL-60 cells. The growth and apoptosis of AML cells were determined using CCK-8, 5-ethynyl-2-deoxyuridine (EdU), flow cytometry, and western blot assays. Glycolysis was evaluated by relative glucose consumption, lactate generation, ATP levels, and hexokinase II (HK2), while glucose transporter 1 (GLUT1) protein expression levels. AKT, phosphorylated AKT (p-AKT), mammalian target of rapamycin (mTOR), and p-mTOR expression levels were assessed by western blot.Results: KLF8 mRNA and protein expression levels were elevated in AML cells (p < 0.01). KLF8 knockdown in AML cells decreased cell viability, EdU-positivity, relative glucose consumption, lactate generation, ATP levels, and HK2 and GLUT1 protein levels (p < 0.01). Apoptosis increased in KG-1 and HL-60 cells, with enhanced Bax and reduced Bcl-2 protein levels, after transfection with sh-KLF8. The relative expression levels of p-AKT/AKT and p-mTOR/mTOR were reduced in KG-1 and HL-60 cells transfected with sh-KLF8.Conclusion: Downregulation of KLF8 inhibits proliferation and glycolysis, and also promotes apoptosis in AML cells via AKT/mTOR pathway.
