Impact of Distance Learning on Mental Health During COVID-19: A Review

The COVID-19 pandemic requires physical activity to reduce its spread. Physical restrictions have a direct impact on the closure of school activities. Distance learning is an alternative for school activities that do not require direct learning communication in one room. However, distance learning can have an impact on students' mental health. This study aims to determine the impact of distance learning during the COVID-19 pandemic on students' mental health

Energy Conservation using Voice Recognition

Conserving Energy is one of the most important issues in all Arab countries and the rest the world. Roads are designed to connect cities, and these roads are constructed and lightened to make the driving more safely and more easily. To reduce the energy consumption, there must be a systematic way to turn the street lights ON or OFF based on the traffic condition. The idea of the work is to design a system that has the capability to turn the lights ON only when cars passing through for some period of time. Our system is designed for the highways streets for example the road that connect any two large cities. We implemented the proposed system using Matlab, and the results show the strength of the proposed system. Keywords: recognition, energy, voice, lights, highway

I Tag, You Tag, Everybody Tags!

Location tags are designed to track personal belongings. Nevertheless, there has been anecdotal evidence that location tags are also misused to stalk people. Tracking is achieved locally, e.g., via Bluetooth with a paired phone, and remotely, by piggybacking on location-reporting devices which come into proximity of a tag. This paper studies the performance of the two most popular location tags (Apple's AirTag and Samsung's SmartTag) through controlled experiments - with a known large distribution of location-reporting devices - as well as in-the-wild experiments - with no control on the number and kind of reporting devices encountered, thus emulating real-life use-cases. We find that both tags achieve similar performance, e.g., they are located 55% of the times in about 10 minutes within a 100 m radius. It follows that real time stalking to a precise location via location tags is impractical, even when both tags are concurrently deployed which achieves comparable accuracy in half the time. Nevertheless, half of a victim's exact movements can be backtracked accurately (10m error) with just a one-hour delay, which is still perilous information in the possession of a stalker.Comment: 8 pages, 8 figure

The Role of Information Management Systems in the Implementation of the Digital Economy Development Strategy

Purpose: The aim of this study is to demonstrate the role that management information systems can play in developing the digital economy.   Theoretical framework. The theory of optimal discrete-continuous control, the principles of Pontryagin, Bellman and Markov and the theory of the development of digital interactions were used.   Design/methodology/approach: The systematic literature review was built from the content analysis of papers from the Web of Science and Scopus database. The papers were analyzed from descriptive, bibliographic, methodological, results and citation characteristics.   Findings: From the results, it was noted that Russia is the absolute position in studies related to digital economies and the role that management information systems can play in developing and achieving strategic development, growth and efficiency.   Research, Practical & Social implications: Many more publications could not be included for  generalisation  reasons  because  the  study  included  data  from  two  databases. Additionally, our research shows that there aren’t many journals that have written about cause-related digital economy.   Originality/value. A model of digital control and development of digital interactions has been proposed and investigated, which takes into account the influence of the "white noise" effect in the system

Quranic Proverbs and Legal Rulings Related to Them

Praise be to God first and last, and prayers and peace be upon our Prophet Muhammad, the illiterate prophet, his family and companions, and those who followed him in goodness, and after. The Noble Qur'an has come as a way and a solid holdout for our salvation, and a savior for us from our slumber. God Almighty has set an example in it of everything. To be a lesson and an immortal lesson in people's minds, with this conviction and in line with the Third International Periodic Conference for Human Sciences, which is tagged ``The Holy Qur'an is an Approach to Building Nations'' and was held by the University of Fallujah, thankfully, we submitted participation in our research tagged ``Quranic Proverbs and Sharia Provisions Related to them''. We looked at it with Qur'anic proverbs, reading, meditating, and researching, and we found that some of them are related to the legal rulings detailed in the books on jurisprudence and the rulings of the Qur'an and their conclusion. As for the introduction, it contains the importance of the topic, the reasons for choosing it, and its desired goals. The second requirement in the legal rulings is related to Quranic proverbs. Then the conclusion mentioned the most important results that we reached and the important recommendations related to the study. We ask God for success and reward. Keywords: proverbs, the Qur'an, rulings, legitimac

Faktor-faktor yang mempengaruhi tekanan kerja semasa pandemik covid-19 dalam kalangan penolong pegawai perubatan dan Jururawat di fasiliti kesihatan di Utara Malaysia

The COVID-19 pandemic has caused healthcare workers such as Assistant Medical Officers (AMO) and Nurses to become depressed, especially who involved in the screening, treatment, and care of patients who have been infected with COVID-19. However, not many studies have been conducted to assess the stress before and during COVID-19. The objective of this study was to identify the factors influencing work stress among AMO and Nurses working in health facilities in northern Malaysia during the COVID-19 pandemic. Correlation test done using SPSS 26. Results of the test show that there is a significant positive correlation between work stress and 3 variables during COVID-19, workload r = 0.504, supervisor support r = 0.294 and role of conflict r = 0.515. The conclusions drawn from this study have proven that workload, supervisor support and role of conflict affect level of work stress during COVID-19

Spectrochemical analysis of soil around leather tanning industry using laser induced breakdown spectroscopy

We report the use of laser induced breakdown spectroscopy (LIBS) to determine the chromium contamination of soil due to effluents from leather tanning industry in Kasur District of Punjab (+ 31 ° 6 ′ 23.2 1 ″, + 74 ° 2 7 ′ 16.2 9 ″) in Pakistan. Calibration curves were constructed by indigenously prepared standard sample and fitting of curves by linear regression. The limit of detection (LOD) was found to be 23.71 mg kg-1. It has been found that the concentration of chromium in the soil is up to 839 mg kg-1 in vicinity of effluent drain and 1829 mg kg-1 in the area of old stagnant pool, which is much higher than the safe limits. Qualitative detection of other elements like Na, Cl, Fe, P, and Si was done from LIBS spectra. The leaching of soil contaminants due to seepage of industrial effluents from deteriorating brick lined drains in horizontal direction has also been observed

Appraisal of Asphalt Concrete with Coal Bottom Ash as Mineral Filler

This study was conducted to access the performance of asphalt concrete produced with coal bottom ash as partial replacement of cement in the mineral filler. The Marshal Mix design method of hot mix asphalt (HMA) samples preparation and testing was adopted. Fifteen (15) samples of HMA compacted and used for volumetric and stability testing at a varying percentage of bitumen contents (5.0, 5.5, 6.0, 6.5, and 7.0%,) following the Asphalt Institute and Nigeria General Specification for Road and Bridges (NGSRB) approach for determining optimum bitumen content (OBC). An Optimum bitumen content of 5.5 % was obtained and used throughout the study. Another set of 15 samples of the HMA were prepared and compacted at varying percentage replacement of cement with CBA in the order of 15, 20, 25, 30, and 35% by volume of cement to determine the optimum dosage of the coal bottom ash that will satisfy the requirements for the strength and durability of wearing course of flexible pavement. The Marshall Stability, flow, and the volumetric properties test results obtained indicated that the samples prepared with 25% CBA as filler with OBC of 5.5% satisfied the requirements of the NGSRB for wearing course of flexible pavement. Hence, the addition of up to 25% CBA by volume of cement in asphalt concrete can reduce the consumption of cement and provide a proper means of CBA disposal
