Pemanfaatan Literasi Digital Dalam Meningkatkan Kreativitas Motorik Anak Berkebutuhan Khusus (ABK)

ABK's motor creativity is said to be good if they are in the right environment, surrounded by people who understand their special needs, both in terms of assisting, guiding and supporting no matter how small they do. Collaboration of digital learning and conventional creativity is one of the strategies developed by HSBE academically/non-academicly. The reading literacy ability of ABK is quite good in understanding writing, pictures, colors but due to verbal limitations it seems difficult to speak and not yet fluent in reading. The need for digital literacy for children with special needs in the form of visual art comics in the form of visualization of picture story books and visualization of digital fairy tales is quite influential in improving the motor skills of children with special needs. The computer science program was attended by ABK grades 2 and 3 because they were already able to operate basic computer systems. This study uses a qualitative descriptive method involving teachers, parents and children with special needs as a sample. The results of this study concluded that 2 children with special needs: 1ADHD – GAP (Attention Deficit Hyperactivity Disorder) and 1ASD – RRF (Autism Spectrum Disorder) have very low ratings in utilizing digital media compared to 3 other children with special needs so that they require extra assistance and learning media

Sistema coaching tutorial: caso de uso en un seminario de titulación

The purpose of the present study was to evaluate the impact of a training program on the level of working memory in a sample of university students. For this, a quasi-experimental study with an active control group was implemented in 29 students of basic teaching and computer systems, applying complex span tasks before and after the intervention. For training, multimídia routines were used for the experimental group and an academic essay elaboration workshop for the control group. The pre-test confirmed intergroup statistical equality for all the measurements used and the post-test, in favor of the experimental group, detected significant difference and large effect size in visuospatial memory and non-significant with medium size, for verbal memory. Additionally, the Raven’s Matrices test was applied to determine effects of training on intelligence, finding no significant difference. Therefore, it is concluded that training based on multimedia routines did not generate gains in intelligence or in working memory, in its verbal domain, although it did in its visual-spatial domain. However, the results must be taken with reservations, due to the limitation represented by the size of the sample, which, if corrected in future interventions, may enrich the findings on the means to improve working memory.

Systematic literature review and metadata analysis of ransomware attacks and detection mechanisms

Ransomware is advanced and upgraded malicious software which comes in the forms of Crypto or Locker, with the intention to attack and take control of basic infrastructures and computer systems. The vast majority of these threats are aimed at directly or indirectly making money from the victims by asking for a ransom in exchange for decryption keys. This systematic literature analysed the anatomy of ransomware, including its trends and mode of attacks to find the possible solutions by querying various academic literature. In contrast to previous reviews, sources of ransomware dataset are revealed in this review paper to ease the challenges of researchers in getting access to ransomware datasets. In addition, a taxonomy of ransomware current trends is presented in the paper. We discussed the articles in detail, the evolution and trend in ransomware researches. Most of the techniques deployed could not completely prevent ransomware attacks because of its obfuscation techniques, but rather recommend proper and regular backup of important files. This review can serve as a benchmark for researchers in proposing a novel ransomware detection methodology and starting point for novice researchers.

The effect of problem-based e-learning content on the learning achievement in basic computer system course (DSK) of the student of informatics engineering education department

This study was aimed at finding out the difference in learning achievement in basic computer system course (DSK) between the students who learned from content e-problem-based learning in experiment class and those who learned from conventional model in control class in learning basic computer system course. This study used quasi-experimental non-equivalent Pretest Post-test Control Group Design. There were three variables involved in this study. Two of them were independent variable and dependent variable. The independent variable was e-problem-based learning and the dependent variable was learning achievement. Another variable which functioned as covariate was students’prior learning achievement. The population consisted of all students of the first semester in Informatics Engineering Education Department. The sample was selected by using simple group random sampling technique. An essay test was used to know the students’basic computer system learning achievement (DSK). The hypothesis was tested by one-way analysis of co-variance (ANACOVA). The results showed that the mean score in the learning achievement of the students who learned from content e-problem-based learning was higher than that of those who learned from using conventional model. Content e-problem-based learning plays the role in improving students’ learning achievement.

Skeleton-based bio-inspired human activity prediction for real-time human–robot interaction

Activity prediction is an essential task in practical human-centered robotics applications, such as security, assisted living, etc., which is targeted at inferring ongoing human activities based on incomplete observations. To address this challenging problem, we introduce a novel bio-inspired predictive orientation decomposition (BIPOD) approach to construct representations of people from 3D skeleton trajectories. BIPOD is invariant to scales and viewpoints, runs in real-time on basic computer systems, and is able to recognize and predict activities in an online fashion. Our approach is inspired by biological research in human anatomy. To capture spatio-temporal information of human motions, we spatially decompose 3D human skeleton trajectories and project them onto three anatomical planes (i.e., coronal, transverse and sagittal planes); then, we describe short-term time information of joint motions and encode high-order temporal dependencies. By using Extended Kalman Filters to estimate future skeleton trajectories, we endow our BIPOD representation with the critical capabilities to reduce noisy skeleton observation data and predict the ongoing activities. Experiments on benchmark datasets have shown that our BIPOD representation significantly outperforms previous methods for real-time human activity classification and prediction from 3D skeleton trajectories. Empirical studies using TurtleBot2 and Baxter humanoid robots have also validated that our BIPOD method obtains promising performance, in terms of both accuracy and efficiency, making BIPOD a fast, simple, yet powerful representation for low-latency online activity prediction in human–robot interaction applications.

Virtual environments for real treatments

Abstract Introduction In the era of evidence-based practice, more evidence of the beneficial impact of physical therapy and rehabilitation interventions have emerged. Kwakkel and Wagenaar's meta-analysis, Carr and Shepherd's work relating to the motor learning concept, and Fiatarone's research of strength training, emphasize the influence of rehabilitation in outcome gains by demonstrating that in conjunction with the therapist's expertise, the most influencing factors are therapy frequency and intensity. Aim To show the problem which is the gap between this knowledge and reality. Discusion Recently published observational studies revealed that patients in rehabilitation facilities receive a very small amount of therapy time during rehabilitation. Virtual reality (VR) technology offers assistance, as it enables patients who have difficulties coping in the “real world” to gradually deal with their problems via the “virtual world”. It provides the user with a real time interactive experience, through visual, audible, tactile or any other kind of feedback. Individuals find themselves in a pleasant, challenging, motivating and “inviting” functional environment, thus tending to forget their limitations or disability. In addition, VR encourages them to reach their goals which are difficult to achieve in any other treatment setting. Conclusions VR is a new, innovative technology utilizing virtual and adaptable worlds, created by sophisticated computer systems with improved graphic capability (hardware) and interactive software allowing one to interact “naturally” with the virtual environment, without the risk and cost of moving the patient into the “real world”. The interactive experience is perceived by both, therapist and patient, as very positive, enabling treatment to continue over time without feelings fatigue or boredom. VR can be created through a variety of tools, simple to complex, cheap to expensive. Basic computer systems with different input and output devices, such as different types of monitors or expensive and sophisticated systems using helmets with small video screens head mounted display have been used. Recently, cheap “on the shelf” video game consoles were adopted by clinicians as valuable tools in treating patients suffering from various pathologies and disabilities. Therefore, therapists are required to manoeuvre and plan treatments in systems where the delineation between therapy and fun is not always clear or controlled. The common practice has to be, as always, somewhere in between the most expensive and sophisticated systems and the “non adaptable” video game consoles. We estimate that in the near future, VR technology will be widely used. Meanwhile, today's technology allows us to take more of the VR advantages to the clinical world.

A synthesis course in hardware architecture, compilers, and software engineering

We describe a synthesis course that provides a hands-on treatment of many hardware and software topics learned in computer science (CS) programs. Using a modular series of twelve projects, we walk the students through the gradual construction of a simple hardware platform and a modern software hierarchy, yielding a basic yet powerful computer system. In the process of building the computer, the students gain a first-hand understanding of how hardware and software systems are designed and how they work together, as one enterprise. The course web site contains all the materials necessary to run this course in open source, and students and instructors are welcome to use and extend them freely. The course projects are modular and self-contained, and any subset of them can be implemented in any order and in any programming language. Therefore, they comprise a flexible library of exercises that can be used in many applied CS courses. This paper gives a description of the approach and the course, juxtaposed against general educational principles underlying meaningful learning.

An outreach venture: bringing computer literacy to rural women in Malaysia

With each IT/ICT development, the digital divide grows wider between the information “haves” and the “have-nots”. In the effort to narrow the gap and to facilitate the adoption of ICT by rural residents, an outreach training course through the Community Communications Development Program was initiated to provide hands-on training in computer literacy to cultivate interest and appreciation in the importance of ICT knowledge and skills. The training was conducted on-site using a mobile unit equipped with 16 computers and peripherals, and was stationed in a selected area for 5 days. Training was divided into morning and afternoon sessions with 15 trainees per session to provide them with one computer each. The men attended the morning session, and the women the afternoon sessions. They were taught for a total of 16 hours on how to operate a basic computer system, Microsoft Word and the Internet facilitated by 3 trainers. The participants had little or no knowledge on IT/ICT and many had never touched a computer before. At the beginning the women had more fear due to their lack of confidence in handling the so-called sophisticated machine than their male counterparts. Compared to the men, women took a longer time to learn keyboarding skills but they had more patience and stronger learning perseverance. There was no difference between rural men and women in terms of attitude and willingness to learn and use the new technology.

Personal computer security: part 1. Firewalls, antivirus software, and Internet security suites.

Personal computer (PC) security in the era of the Health Insurance Portability and Accountability Act of 1996 (HIPAA) involves two interrelated elements: safeguarding the basic computer system itself and protecting the information it contains and transmits, including personal files. HIPAA regulations have toughened the requirements for securing patient information, requiring every radiologist with such data to take further precautions. Security starts with physically securing the computer. Account passwords and a password-protected screen saver should also be set up. A modern antivirus program can easily be installed and configured. File scanning and updating of virus definitions are simple processes that can largely be automated and should be performed at least weekly. A software firewall is also essential for protection from outside intrusion, and an inexpensive hardware firewall can provide yet another layer of protection. An Internet security suite yields additional safety. Regular updating of the security features of installed programs is important. Obtaining a moderate degree of PC safety and security is somewhat inconvenient but is necessary and well worth the effort.

New uses of microcomputers and several forensic science applications of user definable software is discussed. This paper also reviews basic computer systems and cautions for prospective users.

ESL applications of the computer-controlled videodisc player

The essence of the computer's role in language learning can be described in a single word: control. This is not intended to imply control over students, but rather a greater degree of control for students, teachers, and course developers over the spoken and written media in which language is expressed. For teachers, this offers an enhanced ability to present language materials and conduct classes in exactly the way they desire. For individuals or groups of students, it means expanded opportunities to work with materials adapted to their interests and abilities, and greater choice in the style and manner in which they use those materials. For both teachers and students, greater control over language media also offers a reduction in the "inauthentic labor" (Kemmis et al. 1977) involved in the learning process. At our current level of technology, even the most basic computer systems provide much of the necessary control over the written medium. As hardware prices continue to fall, a case can now be made that just one of the functions of this type of equipment-word processing-is sufficient to justify an investment in computer systems for use by both ESL students and their teachers.

A Step by Step Approach to Introducing Computer Technology Into Small and Medium Sized Firms

The enormous advances in micro‐electronics in recent years has resulted in a dramatic decrease in the cost of computing power. Today's small business computer systems costing from £3,000 to £10,000 can do the work of a ten year old machine then costing the equivalent of £250,000. Therefore any company who employs more than one person full time to look after administration and clerical work should now be thinking about using a computer to save time, money and to cut out a lot of monotonous routine work. Additionally, even basic computer systems will provide businessmen with much better and more detailed information on which to base decisions.

Interfacing a microcomputer with the varian E-line series EPR spectrometer

A number of computers and signal averagers suitable for EPR data acquisition and analysis are presently available, but all suffer from disadvantages of high cost and/or low flexibility. We have developed an alternative data system, which is based on the 16-bit LSI-11 microprocessor, and which provides a far superior alternative both in terms of economy and flexibility of application. This report describes the details of the interface between a DEC PDP 11VO3 microcomputer and a Varian Century Series EPR spectrometer. The basic computer system consists of the LSI-11 CPU, 16K or more of RAM memory, dual floppy disks, console, oscilloscope for video display, and a commercially available interface board. This interface board, which plugs directly into the LSI-11 bus, has 16 analog-to-digital channels with 12-bit resolution , as well as two 12-bit digital-to-analog converters. The subroutines which control the functions of this interface board are written in MACRO assembly language, while the main programs and other subroutines are written in FORTRAN. Programs have been written for signal averaging, spectral smoothing, baseline correction, scaled plotting, stacked plotting, spectral addition/subraction, spectral integration, peak search, spectral viewing on the scope and simulation of EPR spectra in solution. Several applications of this system are described.
