Mitigating Sodinokibi Ransomware Attack on Cloud Network Using Software-Defined Networking (SDN)

Sodinokibi Ransomware virus becomes a severe threat by targeting data encryption on a server, and this virus infection continues to spread to encrypt data on other computers. This study aims to mitigate by experiment with building a prevention system through computer network management. The mitigation process is carried out through static, dynamic, and Software-Defined Networking (SDN) analysis to prevent the impact of attacks through programmatic network management. SDN consists of two main components in its implementation, the Ryu controller and Open Virtual Switch (OVS). Result testing mitigation system on infected networks by crippling TCP internet protocol access can reduce virus spread by 17.13% and suppress Sodinokibi traffic logs by up to 73.97%. Based on the percentage data, SDN-based mitigation in this study is per the objectives to make it possible to mitigate Ransomware attacks on computer network traffic.

Student's Perspective on Virtual Laboratory Using Phet as A Media in Conducting Physics Laboratory Activities

The purpose of writing this paper article is to review students' perceptions in the use of PhET-based virtual labs and also to provide a description in comparison to perceptions of virtual lab use from some of the results of previous studies that are relevant to this study. There are five aspects in the perception that will be surveyed, including; (1) aspects of innovation, (2) aspects of benefits (3) aspects of motivation, (4) aspects of effectiveness, (5) aspects of presenting procedures for laboratory activities. The method used is quantitative and qualitative with a Likert scale questionnaire which must be filled in by 40 people and then interviewing the subjects, after the data is collected, percentage data analysis is carried out. The results of the data analyzed show that the aspects of innovation, effectiveness, benefits and presentation of the procedure get a positive view compared to the motivational aspects which are stated to be negative, so this study also shows that the use of virtual labs based on PhET is innovative and effective, but lacks motivation in its use because of essential activities. laboratory is not felt, in presenting the module is required to increase 4C Skills to support 21st century skills

Do mixed martial arts fighters with longer arms win more fights? A robustness analysis

Richardson (2021, Evolutionary Behavioral Sciences) found that mixed martial arts fighters with longer arms won a greater percentage of their fights. The paper used linear regressions on percentage data, but a more appropriate analysis is to use Poisson regression to model the rate of wins. I find that the results of Richardson (2021) remain unchanged when these more robust methods are used.

Fear of Missing Out Scale – A Nationwide Representative CAWI Survey in Poland

Fear Of Missing Out (FOMO) is a growing problem that arouses interest from scientists, media and recipients. Therefore, finding a universal way to calculate the scale of the phenomenon can not only become a common tool for estimating the extent of FOMO occurrence in any country, but also can be considered for managing this phenomenon. The article presents the results of measuring the FOMO scale in Poland in 2018. The project applied a Computer Assisted Web Interview survey of the representative sample (N=1060) of Poland’s internet users aged 15 years plus. Three groups of ‘FOMO level’ characteristics were determined (age was the most influential variable). The original method of recalculation of the FOMO scale results from figures to percentage data was developed in order to present the FOMO scale index. The FOMO items showed good internal consistency and reliability Cronbach’s α = .89, thus complementing previous international studies.

Mortality Rate Due to Pulmonary Fibrosis Associated with Sars-Cov-2 Infection: Scope of Best Fit Regression

In this article mortality rate ( 1) due to pulmonary fibrosis ( 2,3 )associated with SARS-COV-2 ( 4,5 ) is analysed at the early stage of Covid19 infection globally with effect from 21St January to 28th April, 2020 ( 6 ).Pulmonary fibrosis may be considered as one of the major cause of death due to severe acute respiratory syndrome ( SARS-COV-2 )(5) infection . The mortality percentage data(5) within a total ninety eight days are analysed by best fit regression(7) like Polynomial – Morgan Morgan Finney ( MMF ) (7, 8,9 )- Harris model are analysed in detail to compare the scope of best fit with two prime epidemiological parameters like mortality percentage (6) vs duration in days with regular interval of seven days . The entire statistical analysis is computationally analysed by a standard coding of data analysis (11).

Clinical course of cystic fibrosis in children

Annotation. This study is devoted to evaluation of clinical course of cystic fibrosis (CF) in children. The study involved 84 children who were diagnosed with cystic fibrosis. All participants were asked about complaints, life history, physical examination was made, and the results of objective testing and instrumental examination were assessed. The statistical system “IBM SPSS Statistics” version 12 (20) was used using parametric and non-parametric methods of descriptive statistics. Student's criterion was used to assess the significance of the difference between the independent samples, and the Fisher's factor was used for the percentage data. It was shown that 86.91% of subjects had severe or moderate course of CF. Major mutation of CFRT gene F508del/F508del was found in 45.2% children. Common complaints were productive cough (92.9%; р<0.01), failure to thrive (61.9%; р<0.01) and shortness of breath during exercise (40.5%; р<0.01). Results of bacteriologic test of sputum showed significant prevalence of St. aureus (54.0%; р<0.01) and Ps. aeruginosa (38.10%; р<0.01). Patients with severe course of CF had lower rates of FVC, FEV1, PEF, FEF 25%, FEF 50%, FEF 75% than children with moderate and mild course. At the age of 3 years, the diagnosis of cystic fibrosis was established in time by only 76.92% of respondents, which aims to further efforts to improve the quality of its diagnosis.

Design of Alcohol Percent Detection Devices for Food Based on Arduino Uno

Tape is a traditional food that is consumed by many people. Tape made using yeast by fermenting for 3-4 days covered with banana leaves to produce a sweet taste. Besides that the tape also contains alcohol from the fermentation of yeast and rice, if you consume too much tape, the body will feel hot because it does not know what percentage of the alcohol contained in the tape. To overcome such a thing, it is necessary to design a measuring device for alcohol content on food tape in order to know the percentage of alcohol on the tape. The Arduino Uno-based Alcohol Percentage Detection Device Design Series consists of three parts, namely the input part, the control part and the display part. Created to simplify the process of designing Alcohol Percentage Detection Devices on Food based on Arduino Uno. Where the MQ3 sensor is used as an input to get the alcohol percentage from the tape, Arduino Uno can be programmed in real time and the percentage data results will be displayed on LCD I2 Inc. Based on the test results it can be concluded that the MQ3 sensor which functions as an input and outputs sound in the form of a buzzer. The LCD functions as showing the percentage of alcohol on the tape. Tests that have been carried out get the results of the percentage of alcohol content on tape with five consecutive days of testing with an average of 22%, 39%, 46%, 57%, and 67%.
