Indonesia is the world’s second greatest producer of plastic waste after China. The bulk of waste produced accumulates in metropolitan regions due to the increasing population, and the situation has spread to rural areas with a limited population. The residents of the Sinjai Regency have felt the impact of the growing amount of debris, and it is expected to worsen without immediate action. Coastal locations that accommodate waste from land and water are mostly affected by debris. The study was conducted in Bone Bay, Sinjai Regency’s coastline area. The bay’s condition is sheltered to decrease the current strength, but it varies from season to season. Furthermore, it used shoreline survey methodology, where debris grouping consisted of plastics, metal, rubber, glass, clothing, and others. The debris data were calculated and analyzed based on the seasons of the west (January) and east (July). The data were associated with the current pattern model in Bone Bay waters based on the season. In January and July, 86% of waste was plastic, 3% was metal, 4% was rubber, 2% was clothing, while 5% and 4% were glass. No other types of waste were identified in January, while 1% was detected in July. Garbage that enters through rivers, garbage deposited by local residents, and tourism activities at the four observation areas are all contributing to the presence of waste in Sinjai’s coastal area.

Manufacturing and processing industries usually consume large quantities of materials and energy in the course of their operations. The energy supplied for high-temperature processes are used partially for the actual technical process and between 30 to 40% of the energy escapes through the walls of the reactor into the atmosphere, leading to a high degree of thermal inefficiency and fuel consumption. This paper studies the thermal behaviour of insulating refractory bricks produced from a blend of fireclay and agroforestry wastes. The fireclays used were obtained from Ukpor deposit in Anambra State (Latitude 5.95°N, Longitude 6.92°E), Osiele deposit in Abeokuta, Ogun State (Latitude 7.18°N, Longitude 3.45°E) and Kankara Katsina State (Latitude 11.93°N, Longitude 7.41°E), all of which are in Nigeria. Samples were prepared with various weight percentages (60–100 wt.%) clays and (0–40 wt.%) of agroforestry waste, with grain sizes between 212 and 600 µm. Raw materials and the developed refractory bricks were characterised using appropriate standard techniques. The chemical, mineralogical constituents and phases present in the microstructure were examined. Physical and thermo-mechanical properties were investigated. The insulating refractory bricks developed have porosity of 78.83% , cold crushing strength (CCS) 3.144 kN/m2 and thermal conductivity 0.04–0.046 W/(m∙K) that compare favourably with imported bricks 75–85%, 2.756 kN/m2 and 0.049 W/(m∙K) in both physical, mechanical and thermal properties respectively. The reason is that the agroforestry waste used (coconut shell), served to create the pores that improve insulation after burning. Also the ash that remains serves as reinforcement to improve the mechanical properties. The thermal behaviour of the bricks was studied using Finite Element Method and shows a strong correlation with the experimental findings. This indicates that the produced insulating bricks have the thermal properties required for insulation of furnaces.
Wonder
Authors: Keil Frank C. 
Published: July 2022

How we can all be lifelong wonderers: restoring the sense of joy in discovery we felt as children.
From an early age, children pepper adults with questions that ask why and how: Why do balloons float? How do plants grow from seeds? Why do birds have feathers? Young children have a powerful drive to learn about their world, wanting to know not just what something is but also how it got to be that way and how it works. Most adults, on the other hand, have little curiosity about whys and hows; we might unlock a door, for example, or boil an egg, with no idea of what happens to make such a thing possible. How can grown-ups recapture a child's sense of wonder at the world? In this book, Frank Keil describes the cognitive dispositions that set children on their paths of discovery and explains how we can all become lifelong wonderers.
Keil describes recent research on children's minds that reveals an extraordinary set of emerging abilities that underpin their joy of discovery—their need to learn not just the facts but the underlying causal patterns at the very heart of science. This glorious sense of wonder, however, is stifled, beginning in elementary school. Later, with little interest in causal mechanisms, and motivated by intellectual blind spots, as adults we become vulnerable to misinformation and manipulation—ready to believe things that aren't true. Of course, the polymaths among us have retained their sense of wonder, and Keil explains the habits of mind and ways of wondering that allow them—and can enable us—to experience the joy of asking why and how.
FG-Droid: Grouping based feature size reduction for Android malware detection
Authors: Arslan Recep Sinan 
Published: July 2022

Background
The number of applications prepared for use on mobile devices has increased rapidly with the widespread use of the Android OS. This has resulted in the undesired installation of Android application packages (APKs) that violate user privacy or are malicious. The increasing similarity between Android malware and benign applications makes it difficult to distinguish them from each other and causes a situation of concern for users.

Methods
In this study, FG-Droid, a machine-learning based classifier, using the method of grouping the features obtained by static analysis, was proposed. It was created because of experiments with machine learning (ML), deep neural network (DNN), recurrent neural network (RNN), long short-term memory (LSTM), and gated recurrent unit (GRU)-based models using Drebin, Genome, and Arslan datasets.

Results
The experimental results revealed that FG-Droid achieved a 97.7% area under the receiver operating characteristic (ROC) curve (AUC) score with a vector including only 11 static features and the ExtraTree algorithm. While reaching a high classification rate, only 0.063 seconds were needed for analysis per application. This means that the proposed feature selection method is faster than all traditional feature selection methods, and FG-Droid is one of the tools to date with the shortest analysis time per application. As a result, an efficient classifier with few features, low analysis time, and high classification success was developed using a unique feature grouping method.
Impact of Maternal Education and Age on Weight of Child at Birth: Use of Multinomial Logistic Model
Authors: Bartholomew D. C. , Biu O. E. , Enegesele D. 
Published: July 2022

The World Health Organization (WHO) prescribed 2.5 kilograms to 4.2 kilograms as the standard for normal birth weight (NBW) and every child whose birth weight is below the lowest bound is regarded as low birth weight (LBW) while above the highest bound is regarded as macrosomia. The odds for a LBW child to die as reported is about 40 times high when compared to a NBW child and these overwhelming death records are higher in developing countries. Therefore, urgent research about the causes of LBW especially in developing countries is very necessary and this motivated this research in Nigeria. In this paper, the Multinomial Logistic Regression (MLR) model was applied to secondary data from the 2018 Nigerian Demographic and Health Survey (NDHS) report to predict the probability of giving birth to NBW and macrosomia babies referenced to LBW babies. The maternal education level and age were considered as the predictor variables. The data was naturally stratified by maternal education level, that is (1 = Higher Education, 2 = Secondary Education, 3 = Primary Education, and 4 = No Education). The equal sample allocation technique which assigns equal stratum sample sizes (ni = 200 for the ith maternal education level) was adopted. The 800 sample size was reduced to 735 after screening for outliers in the maternal age variable. Considering the 54 LBW babies, 57% (0.5741) were from mothers with no education. The results showed that maternal education level and age have causal effects on child birth weight in Nigeria. Younger mothers (less than 28years) are 96.5% likely to have LBW babies while mothers who attained a minimum of primary, secondary, and higher education are 88.00%, 82.00%, and 57.90% likely to have NBW babies respectively when compared to those with no formal education. The research recommends that mothers should acquire at least primary school education and early child marriage (less than 28years) of the girl child should be discouraged.

Aims: Amendment of ferralitic soils of Ngaoundere (Cameroon) by rock materials, so-called petrofertilizer, can be a promising solution to improve their fertility and thus enhance crop yield.
Study Design: In the present study, the influence of pyroclastic powder on the growth of the common bean (Phaseolus vulgaris L.) was assessed.
Place and Duration of Study: Department of Biological Sciences. The sowing was done on June 13, 2017 until 2 septembre.
Methodology: An experimental design with four (04) different treatments was implemented: 0 g per pot (0% of pyroclastic: the control), 150 g per pot (10% of pyroclastic: P10 Treatment), 300 g per pot (20% of pyroclastic: P20 Treatment) and 450 g per pot (30% of pyroclastic: P30 Treatment). The pyroclastic powder was applied at three different (03) stages: sowing, germination, and flowering stage. All the treatments were irrigated with 250 ml of water once every 3 days during the growing stage.
Results: Growth parameters, seed yield, and seeds nutritional values were measured. Results revealed that seeds yield from the treated pot using 30% of pyroclastic powder is
4.2 times greater than that of the control. Globally, pyroclastic powder improved the nutritional values of common bean seeds compared to the Control. Fertilizing the soils at the sowing stage significantly (p<0.05) improves the values of the studied growth parameters. The protein content of seeds from treatment at the sowing stage was 1.05 and 1.11 times greater than that from treatment at germination and flowering stages.
Conclusion: The application of 30% of pyroclastic powder at the sowing stage is recommended for the cultivation of the common bean in the Adamawa (Cameroon).

Authors: Bonganciso Jade G. , Bonganciso Ruel T. 
Published: July 2022

The quality of professional life is the degree on how the individuals feel in relation to their work as care providers. For helping professionals, it has positive and negative aspects that influence their professional quality of life. The present descriptive study focused on the above phenomenon of the teacher-guidance designates. More specifically, this study explored the level and significance difference of the three components of professional quality of life. The participants were the 20 secondary teachers (N = 20) of the Division of Cadiz City. The ProQoL – 5 Scale was used as a psychometric tool for the evaluation of the quality of professional life; and an interview guide was conducted during the focus group discussion. Frequency, mean, Mann – Whitney U test and Kruskall – Wallis test were used for data analysis. Results show that a high level of compassion satisfaction was evident towards 21 – 30 years old guidance designates. Also, guidance designates who were teaching Social Science showed a high level of compassion satisfaction. On the other hand, the professional quality of life of the guidance designates showed no statistical significance regardless of sex, age, area of specialization and years of service as guidance designates. The participants generally showed an average level of satisfaction and exhaustion as care providers. Hence, the guidance designates’ attributes may suggest that through their coping abilities they settle their emotional residues due to empathetic engagement.

Published: July 2022

Introduction: Amyotrophic lateral sclerosis (ALS) is a fatal neurodegenerative disease that can cause motor neuron degeneration in the spinal cord and motor cortex. Although most cases of ALS are sporadic, copper-zinc superoxide dismutase-1 (SOD1) mutations are responsible for 10%-20% of familial ALS.
Objective: Studying neuromuscular junctions in various age groups to see how they vary in structure.
Methods: From male hemizygous carriers (B6SJL-Tg (SOD1-G93A) 1Gur/J) and female B6SJL/F1 hybrids, female G93ASOD1 transgenic mice and age-matched wild-type (WT littermate partners, both were purchased from Jackson) laboratory. The animals were kept in an environment with controlled humidity and temperature, and 12:12h light was performed in a dark schedule, and sterile rodent food and sterile food were provided without specific pathogens.
Results: WT and SOD1 are present in 40, 60, 90, 120 days of mice Inside the Tibialis anterior of G93ASOD1 mice (TA) and gastrocnemius (GN) construction. The neurofilament heavy polypeptide (tubulin, green) points to the presynaptic end. α-Bungarotoxins (BTX, white) mark the postsynaptic space, and synaptophysin (p38-1, red) is used for synaptic vesicles. In the following research we demonstrate that in 40 days of mice WT and SOD1 neither of them degraded while in 60 days of mice a slight denaturation occur in WT and SOD1 Further in 90 days of mice the degeneration is not serious about 60% to 70%. Furthermore, the deterioration in mice after 90 days is only 60-70 percent significant.
Conclusion: NMJ inervation has appeared Disappearance, loss of motor axons, and huge structural damage to the NMJ at 60 and 90 days. Structural changes in presynaptic and postsynaptic structures and a gradual decrease in synaptic vesicles observe.
