Authors: Muniandy Mageswary N , Zaharudin Rozniza
Published: July 2024

Hearing-impaired students struggle with writing, frequently make errors, and have limited sentence construction skills. Current learning platforms like Google Classroom do not have sign language support or content specifically designed for students with lower written comprehension, leading to frustration, sentence structure difficulties, and decreased motivation, as their unmet needs affect academic achievement. This study aimed to investigate if Let's Write, a mobile application, could address the essential writing skills needed for simple sentences, specifically focusing on the Preposition of Positions. The goal was to improve handwriting, accuracy, sentence structure, and punctuation by comparing it to the Google Classroom learning platform. The study was conducted using an experimental design, and the participants were chosen from government schools in Perak and Penang using purposive sampling. The study divided 80 hearing-impaired students into control (n=40) and experimental (n=40) groups, each using a different platform. Pre-tests, treatment (platform use), and post-tests were used to measure academic progress, while questionnaires assessed usability and motivation. The results showed that the Let's Write application provided a significantly more user-friendly and interactive learning environment. Students using the Let's Write application displayed higher self-assessment, focused on learning from mistakes, sought independent knowledge, and reported overall satisfaction. Importantly, the Let's Write application group showed greater academic improvement than the Google Classroom learning platform group. This suggests that mobile applications, particularly those incorporating sign language, can greatly enhance learning for hearing-impaired students by improving usability and learning motivation. It highlights the importance of tailored educational technologies in bridging the achievement gap. The study provides valuable insights for educators and developers to refine digital learning tools further.

The northern coastal area of ​​Palang Sub-District is a densely populated area in the Tuban district with high differentiation of economic activities. The large population and heterogeneous community activities on the northern coastal of Palang Sub-District have the potential to become a source of pollution which results in a decrease in seawater quality. The research aim is to analyze seawater quality on the north coast of Palang Sub-District based on seawater quality parameters and the spatial distribution of the pollution index. It is hoped that this research can help local governments to monitor and control water pollution in the area. Sea water sampling was carried out in the dry season for 2 days at high and low tide conditions. This research analyzes the concentration values ​​of BOD, COD, NO3-, TSS, detergent, oil & grease, pH, temperature, and Total coliform compared to seawater quality standards of PP RI No. 22 of 2021 Appendix VIII on Marine Biota. The spatial distribution of the water quality pollution index is the result of interpolation using the Inverse Distance Weighted (IDW) method from the results of measuring test parameters. The Pearson Correlation statistical test was carried out to determine the level of correlation between the parameters selected in determining water quality. The results of the research show a decline in the quality of the northern coastal waters of Palang-Tuban District with several parameter concentration average values ​​exceeding the quality standards, namely pH = 6.9 (QS = 7.0-8.5); TSS = 29.2 ppm (QS= 20 ppm); Nitrate = 0.4 ppm (QS = 0.06 ppm), BOD5 = 54.8 ppm (QS= 20 ppm), COD = 112.5 ppm (QS= 100 ppm). The water quality status shows that the water conditions are moderately polluted (ST1A), lightly polluted (ST1B-ST5B), and good conditions (ST4C & ST5C). Controlling and reducing the pollution load entering coastal waters needs to be carried out to prevent the quality of coastal waters from decreasing further. One of them is by creating wastewater treatment at every fishing port and fish auction.

Methods: This prospective observational study was conducted in the Department of Gynae and Obstetrics of Dhaka Medical College Hospital, Dhaka, Bangladesh during the period from March 2010 to August 1010. Result: Total 66 patients were diagnosed with placenta previa. We found, the majority (42%) of participants were aged between 26-30 years and with lower socio-economic status significantly associated with higher prevalence due to lack of regular antenatal care. The majority were admitted at 35-37 weeks gestation, with the highest perinatal loss occurring before 30 weeks. Initial bleeding was generally small, and many presented with labor pain and anemia. Ultrasonography diagnosed 55% of cases, with cesarean sections frequently used, leading to better outcomes compared to vaginal deliveries. Severe postpartum complications like hemorrhage and urinary tract infections were common in more severe cases. Conclusion: Placenta previa is a major cause of maternal and perinatal morbidity and mortality. Early registration, regular antenatal care, early detection of high-risk cases, and timely referral to higher centers with good NICU services and blood bank facilities can help prevent these adverse outcomes.

Background: Breast cancer with advanced stages at a young age is a significant new challenge in Sudan. The purpose of this study was to determine the most common presentations of breast cancer patients in western Sudan. Methodology: For this retrospective descriptive investigation, materials for 183 breast cancer patients were obtained from two histopathology centers (Kordofan histopathology center and El-Obeid International Hospital). A full coverage sample was collected, spanning from January 2019 to May 2024. All data pertaining to the patient's essential identifying, clinical, and histological data were gathered. Results: This study looked at 183 breast cancer patients (177 (96.7%) women and 6 (3.3%) men). Their ages ranged from 20 to 90, with a mean ± standard deviation of 50.78 ± 13.6 years. The majority of participants were aged 41-50 years, followed by ≥61 and 51-60 years, with 50/183 (27%), 43 (23%), and 35 (19%), respectively. For clinical appearance, the most common skin change was unremarkable, followed by ulcerated skin change, which accounted for 127/183 (69%) and 48 (26%) respectively. Conclusion: Breast cancer with advanced stages upon presentation is common in Sudan. The majority of patients presented at a younger age and had distinct initial manifestations.

Background: Pesticide ubiquity and extensive applications have attendant public health implications. This study examines the immediate and prolonged inhalation toxicity of various commonly used insecticides in male Wistar rats. Methods: 192 male Wistar rats were utilized and kept in regular housing. The study was carried out in three stages: a preliminary test, an acute test, and a sub-acute. Wistar rats, housed in an improvised chamber, were exposed to varying doses of insecticides in each phase to assess their toxicities to insecticides. For comparativeness, we withdrew 57 of the rats from exposure to ascertain possible recovery. The study included monitoring behavioral changes, recording mortality rates, and conducting necropsies to evaluate organ pathology. Dose-response relationships were analyzed to determine lethal doses (LD50) and potential sublethal effects. Results: Overall, we found a dose-related increase in the severity of the response, which potentially indicates an alteration of a specific biochemical process. The range-finding test assessed the effects of DD Force, Sniper, Industrial Camphor, Edible Camphor, Kerosene, and combined pesticides. It revealed significant physiological impacts followed by mortalities at specific dosage levels. Subsequent acute toxicity testing determined LC50 values for each insecticide. Rats showed a dose-dependent health deterioration following sub-acute exposure, particularly in the combined pesticide group, indicating synergistic toxicity. Conclusion: Exposure to the combined pesticide at high doses was associated with severe toxicities in the tested rats. This evidence suggests that commonly used pesticides could potentiate adverse health outcomes when results are extrapolated in humans.

Graves’ disease is by far the most common cause of hyperthyroidism in children [1]. In this specific population, the hyperthyroidism is willingly biochemically overt and clinically severe [2]. Childhood hyperthyroidism may also cause accelerated growth and bone maturation, and eventually deterioration in academic performance, hence the need for a good screening and a better management. children with GD require prompt treatment, for the most of cases it’s initially medical. But once this fails or is not possible, a definitive treatment should be considered [3]. For the antithyroid drugs use, we currently consider no difference in biochemical control between DT and BR [2,4], unlike previous approaches which argue in favor of the use of bloc-replace method in children [5-6]. However, for a curative treatment, total thyroidectomy is the preferred option for GD patients younger than 10 years [3]. We report the case of a girl who was 2 and a half years old in the moment of diagnose, and whom we followed for Graves' disease for 1 and a half years. Ethical considerations: In accordance with the regulations in force, informed consent, written and verbal, was provided to the parents of the child before the publication of this work.

Employees ability to carry out their duties can be seen through their performance, so employee performance is significant for the company's success. Another important thing that companies must pay attention to regarding their human resources is the issue of job satisfaction. Job satisfaction is an employee's attitude towards their work, the difference between the rewards received by the employee and what is considered something that should be received. Apart from the sense of job satisfaction felt by employees, the compensation provided by the company is also a factor in improving performance. Based on the urgency of the problem above, this research aims to analyze the influence of transformational leadership and compensation on job satisfaction. The theoretical benefits of this research are expected to contribute to understanding leadership theory in different conditions and situations, which better explains how someone becomes a leader and emphasizes character characteristics and actions adopted to increase compensation and job satisfaction in the organization. This research method uses a quantitative approach. The population in this study were all employees at BPR Malang Raya, totaling 471 employees. Meanwhile, the sampling technique in this research used the Slovin formula with results of 175 employees. The results of the analysis show that transformational leadership positively and significantly affects job satisfaction. The research above states that compensation positively and significantly affects job satisfaction. Transformational leadership can direct subordinates to do something to achieve satisfaction in professional development and working relationships with superiors and co-workers to create a feeling of happiness about the work produced.

In this investigation, Nb2O5-α-Fe2O3 nanocomposites were synthesized by modified sol-gel method. The obtained materials were characterized by different techniques such as powder X-ray diffraction (XRD), field-emission scanning electron microscopy (FESEM), Brunauer-Emmett-Teller (BET), UV-vis diffuse reflectance (UV-vis spectroscopy). The catalyst was found to have a particle size in the region of 20-42 nm with a high surface area. The effects of the catalyst dose, the pH value, UV power, addition of H2O2 and scavenger on the photocatalytic efficiency were investigated. This study presents a strategy to eliminate highly toxic and persistent dyes such as DB 199 dye. It was observed that the nanocomposites showed maximum response with more than 80% degradation of DB 199 dye in 100 min.
Russian Nationalism

A shared sense of identity within a state is a stabilising structure allowing a focus for citizens to rally around. As a multi-ethnic state Russia has always been faced with the problem of how to imbue its citizens with a sense of identity that strengthens the state without causing dissent among the majority ethnic Russians or the many different minorities encapsulated within its territory. The choice between a civic based identity and an ethnically based national identity has faced the ruling apparatus for hundreds of years, and still poses a problem for both the people and the government of today’s Russia.
Economic Crisis In Perspective

Published: July 2024

Uncertainty is a powerful concept in many ways, particularly so for economic ideas. The convictions before the financial crisis in 2007-8 that business cycles had been tamed was not the first time neglect of uncertainty proved devastating. This essay discusses the famous Currency controversy in mid-19th century Britain and the failure to take uncertainty into consideration, which ultimately lead to the banking crisis of 1847. The unintended consequences of the Bank Act of 1844 revealed themselves spectacularly in 1847, in the same way convictions about the Great Moderation fell apart in 2007-8.
Imperialism and Hunting
Authors: Penney Jessica
Published: July 2024

Hunting is an essential part of socio-economic life for Indigenous peoples worldwide. For many, it allows for cultural continuity and is a source of partial or full income. This article intends to explore how hunting practices have been impacted by European imperial views of “progress” over the past 400 years, and how perceived progress can be destructive to some aspects of social life. To do this, the place of Indigenous hunting practices in global processes is examined. From the 17th century fur trade, to the fall of fur, recent anti-fur campaigns and environmental movements, ‘Western’ views on fur and hunting have grounded Indigenous practices in the global economy. This is seen through the application of world-systems and underdevelopment theory.
