Effects of Long-duration Microgravity and Gravitational Transitions on Fine Motor Skills.

Assess the effects of long-duration microgravity and gravitational transitions on fine motor skills using a tablet-based test battery of four fine motor tasks: Pointing, Dragging, Shape Tracing, and Pinch-Rotate. While there have been some studies on fine motor skills in microgravity, few have measured the fine motor skills that are core components of interaction with computer-based devices, and none have measured performance systematically, to include preflight, inflight, and postflight space mission time periods. Seven astronauts completed the Fine Motor Skills test battery 30-40 times before, during, and up to 30 days after standard duration International Space Station missions, while a matching set of seven ground-based control participants also completed the battery over a comparable period of time. Response time and accuracy were the primary outcome measures. Relative to controls, astronauts experienced fine motor skill decrements at gravitational transitions (first week on orbit, and first month post landing). No decrements were found inflight after the first week of adaptation. Gravitational transitions appear to negatively impact fine motor skills needed to operate small controls with accuracy, such as those on touchscreen interfaces. This raises concerns for future long-duration crewmembers who will land on a planetary surface and need to perform critical tasks accurately, such as configuring spacesuits, powering up a habitat, or teleoperating rovers. Results from this study highlight the need for confirmatory research, and the possible need for countermeasure development. The Fine Motor Skills test battery may have application outside of NASA as a fine motor skills diagnostic screening, rehabilitation, or readiness-to-perform tool.

Security approach for instant messaging applications: viber as a case study

<span>A variety of internet-based applications are widely used in our animation activities because they provide free and useful services. These applications, such as Instant Messaging, can be run via the web, mobile, or computer-based devices. Therefore, the security and privacy of user data over these apps have been concerned in recent years because of sensitive and confidential information considerations. Consequently, many instant messaging applications, like Viber, have various security and privacy issues that need to be understood and resolved. Viber users reached 800 million, and they increased dramatically due to the efficient services that this app provides. Hence, a loophole in an application’s design may allow illegal access to the app and gain confidential and sensitive data. In this article, we proposed a security approach for Viber to safeguard user confidential data and sensitive information. The proposed approach involves two theoretical solutions: Short message service (SMS) authentication code and the physical hardware number to prevent illegal access to user data. Several scenarios are adopted to assess the proposed approach and achieve security and privacy for the user information.</span>

Automated Counting of Daphnid Neonates, Artemia Nauplii, and Zebrafish Eggs: A Proof of Concept.

In aquatic invertebrate (e.g., daphnids and Artemia sp.) and zebrafish cultures, in ecotoxicological bioassays, or when addressing complex population-level experimental designs, the counting of an organism's progeny is often required. This counting process is laborious, repetitive, and time-consuming, potentially posing health hazards to the operators, and necessarily entailing a higher likelihood of human error. We present an experimental evaluation of a computer-based device for counting neonates (Daphnia magna, Daphnia longispina, and Ceriodaphnia sp.), nauplii (Artemia salina and Artemia franciscana), and zebrafish (Danio rerio) eggs. Manual counts by an experienced technician were compared with the corresponding automated counts achieved by the computer-based counting device. A minimum of 55 counts/species was performed, with the number of counted organisms being up to a maximum of 150 neonates of Ceriodaphnia dubia, 200 neonates of D. magna and D. longispina, 200 nauplii of A. franciscana and A. salina, and 500 zebrafish eggs. Manual and automated counts were both performed in culture medium solutions of 50 ml of volume. Automated counts showed a mean relative acccuracy of 98.9% (97.9%-99.4%) and a relative standard deviation of 1.72%. The results demonstrate that the computer-based device can be used for accurately counting these aquatic organisms. This computer-based counting might be extended to other organisms of similar size, thus facilitating reproduction and life-cycle ecotoxicity tests.

Cyber Law Vis-À-Vis Net Banking in Indian Sector

Technological progress is like an axe in the hands of a pathological criminal” -Albert Einstein. The above-mentioned line quoted by Albert Einstein has put forth the crux of this paper more efficiently. E-Banking is a branch of E-commerce, which has been established and has drastically developed in India recently. The process of banking has been redefined completely after the establishment of E-banking to a whole new level. The process of banking has always been considered as a hectic process that consumes humongous time and effort. Net banking has made the procedures and protocols of banking simpler and easier. The simpler and easier, there is an awaiting question of internet frauds and threats, which arises as a barrier for the further development of online banking. These sorts of mala fide activities by hackers and other digital wrongdoers build a barrier to further explore the scope of technology. We can put forth the definition of cybercrime as any offense/crime committed via any computer or any other computer-based devices. The primary prey for these hackers/digital wrongdoers are the monetary related institutions like banks or any other financial institution. Nevertheless, this paper examines the various encounters and cases, where the E-banking was at stake. It will further describe the history and evolution of E-commerce in India. It will also put forth measures to battle fore-coming threats in the field of E-banking.

The power in your pocket – uncover smartphones for use as cutting-edge microscopic instruments in science and research

Abstract Since the development of the first light microscope over 400 years ago, the technology has continuously evolved and established itself as a powerful tool, especially in biology, diagnostics and point-of-care (PoC) applications. The miniaturization of mass-produced actuators and sensors enables the use of technically extremely complex functions in smartphones at a very low price. They can be used to implement modern microscopy methods for use in places where access to such techniques is often very limited. In this review, we show how easy it is to integrate a smartphone into the everyday microscopy-imaging routines of biology research. Such devices have also been used to identify diseases directly at the patient. Furthermore, we demonstrate how constantly increasing computing power in combination with the steadily improving imaging quality of cameras of handheld devices enables the realization of new biomedical imaging methods, which together with commercially available and 3D-printed components make current research available to a broad mass. Examples are smartphone-based super-resolution microscopy (SRM) or task-specific single-board computer-based devices, which can analyze plankton in sea water.

They needed someone to design, implement, and conduct a field test of a new computer-based device that measured the phasor equivalent of voltage and current sine waves. Knowing little about the technology and method, I went to a project meeting where Prof. Arun Phadke from Virginia Tech (VT), the principal investigator and primary creator of the concept, was leading the planning.

Blurring of the Human and the Artificial: A Conceptual Clarification

Due to certain progress made in Artificial Intelligence (AI) and related fields, there is a common agreement that we are facing a blurring of the human and the artificial. This presentation will argue that this agreement is rather one that pertains to anthropomorphic notations when dealing with computers and computer-based devices, as opposed to one that is justified by engineering results. In fact, the language used to describe mechanic functions hides what ontologically occurs, and how the autonomy of humans can be endangered. The clarification intended here uses the philosophical distinction between agents and patients and translates it into the systems theoretical distinction between self-organising systems and non-self-organising entities.

Limits of stability LoS and postural stability PS tests were used to evaluate postural control by Biodex Balance System and SenseWear Armband was used for physical activity assessment. All measurements were applied before and after the training. Results: Significant improvements occurred in LoS and PS scores in both groups after interventions p

Aplikasi Absensi Berbasis Android Menggunakan Differensi Fitur Biometrika Wajah

Technological developments have changed the way of works in a variety of human activities that were originally manual to digital where data and information can be processed anytime and anywhere. The development of mobile devices which is characterized by the increasing number of users of smart devices or smartphones has now made it possible to do a variety of jobs thanks to its quite high computing capability. Digital attendance is currently being developed on computer-based devices using authentication using fingerprint. This can cause a long queue if applied to an institution or company with a large number of employees and tight working hours. Digital attendance using smartphone devices especially Android has now begun to be developed to utilize smartphone devices as an alternative to recording employee attendance. The problem of digital attendance on smartphone devices especially Android is the fingerprint authentication facility is only available on devices with prices that are still relatively expensive, making it difficult to reach by employees, so cheap authentication that can be used today is using facial features. This study uses facial biometrics features to validate and authenticate the identity of the face owner using simple feature differentiation values so as to minimize the complexity of the authentication process while maintaining the accuracy of the authentication results. With a threshold difference of 30 - 50% the system built can detect the owner's face accurately with different lighting and positions.

United States regulatory approval of medical devices and software applications enhanced by artificial intelligence

In the United States, regulatory oversight of medical devices has evolved with the changing technology. With the introduction into routine clinical practice software applications and computer-based devices, the U.S. Food and Drug Administration (FDA) has further defined categories of risk and intended use to better uphold patient safety, while encouraging innovation in medical technology. However, as new software technologies such as artificial intelligence (AI) are developed, refined, and introduced into the healthcare sector, there will be a need for regulatory bodies to rapidly respond. In the current review, we discuss the evolution of US FDA oversight of medical devices, initially of hardware, and the present stance on medical software applications, including devices augmented with artificial intelligence.

Assessment of sex analysis in studies of technology-based interventions to alleviate caregiver burden among caregivers of persons with dementia.

BackgroundWith an increase in the number of family caregivers for persons with dementia, caregiver burden is a major concern. Defined as computer-based devices and programs, technology has been identified as an intervention to address this issue. However, to date, there is little consideration of sex differences among caregivers in the design and planning of these interventions.ObjectiveTo systematically review the literature on technology-based interventions for caregivers of persons with dementia and report the frequency and approaches of sex-based analysis.MethodsThe literature was systematically searched for reviews of technology-based interventions for caregivers of persons with dementia. All titles and abstracts of publications included in the retrieved reviews were screened using pre-determined inclusion and exclusion criteria. Full text articles that met the inclusion criteria were included for analysis.ResultsFour reviews were identified and 19 articles representing 17 studies were retrieved. Among these studies, only four examined outcomes by sex. In the studies that examined outcomes by sex, three reported significant differences (p < 0.05) between male and female caregivers.ConclusionsThere is currently a lack of (1) sex-based analyses, (2) inclusion of males and (3) provision of sex-specific information in studies of technology-based interventions for caregivers of persons with dementia.

Variation in communication strategies in amyotrophic lateral sclerosis during a two-year follow-up

ABSTRACTWe report on how functional capacity of communication and the use of augmentative and alternative communication (AAC) technology changed in persons with amyotrophic lateral sclerosis (ALS) and progressive dysarthria during a period of two years. The initial sample comprised 30 participants, nine of them survived the whole two years. The data was gathered in 157 communication assessments by a speech-language pathologist. Functional capacity of communication was evaluated with combined severity scales of speech and upper and lower limb function. Communication strategies used were gathered based on the participants’ own reports, and their use was confirmed during the clinical visits. A total of 57% of the participants either supported or substituted their natural speech with high- or low- technology strategies. The majority of them reported that they used high-technology rather than low-technology AAC as the main communication means after speech had deteriorated. The classification of functional capacity of communication changed in 63% of participants, more in bulbar than spinal-onset ALS as the disease progressed. Natural speech is a strong means of communication and not effortlessly replaceable. However, AAC means, such as handwriting, text-to-speech devices and computer-based devices, are essential for persons with ALS as their speech deteriorates. Several AAC strategies to augment deteriorated speech and replace natural speech are often needed. Functional capacity of communication and its individual changes along the disease progression must be taken into account during the continuing communication aid processes.

Can a tablet-based cancellation test identify cognitive impairment in older adults?

Background and objectiveThere has been a growing interest in using computerized cognitive assessment to detect age-related cognitive disorders. We have developed a tablet-based cancellation test (e-CT), previously shown as a reliable measure of executive functions and free of effect of familiarity with computer-based devices in healthy older adults. This study aimed to investigate the influence of demographics and current daily use of computer-based devices in older adults with Mild Cognitive Impairment (MCI) and Alzheimer’s disease (AD). We further studied the ability of the e-CT to discriminate MCI and AD patients from older adults with normal cognition (NC).MethodsThe e-CT was administered to 325 older adults (NC = 112, MCI = 129, AD = 84). Subjects also performed the K-T test, a paper-and-pencil cancellation test from which the e-CT was developed. Multiple linear regression analyses were conducted to assess the contribution of demographics and current daily use of computer-based devices on the e-CT in patient groups. The Receiver Operating Characteristic (ROC) curves and the Area Under the Curve (AUC) were established to compare the efficacy of the e-CT and the K-T test to classify subjects into diagnostic groups.ResultsIn the MCI group, age (B = -0.37, p<0.001) and current daily use of computer-based devices (B = 5.85, p<0.001) were associated with the number of correct cancellations of the e-CT. In the AD group, only current daily use of a computer-based device was a significant contributor (B = 6.28, p<0.001). The e-CT (AUC = 0.811; 95% confidence interval [CI]: 0.756–0.867) and the K-T (AUC = 0.837; CI: 0.787–0.887) showed good and comparable diagnostic accuracy to discriminate between MCI and NC subjects. To discriminate between NC and AD, both tests showed high diagnostic accuracy, with the AUC values of 0.923 (CI: 0.876–0.971) and 0.929 (95%CI: 0.886–0.972) for the e-CT and the K-T, respectively.ConclusionThe e-CT presents satisfying discriminative validity and is a promising tool for detection of early cognitive impairment in older adults.

Computer Technology to Improve Medical Information in Bangkok, Thailand

Building hospital applications based on services allow hospitals and other organizations to cooperate and make use of business functions. Hospital information systems that involve extensive information exchange across hospitals and organization boundaries, such as patient profiles, can easily be automated. Service-based applications can be constructed by linking services from various providers using either a standard programming language or a specialized workflow language. This paper reviews the use of computer technology which supports health services in Bangkok, Thailand by developing a survey of health services in hospitals, in which the focus is on the attitudes and competence of medical students and physicians, and the availability of health services equipment; and analyzing and providing guidance via a web service that supports health services. A prototype of a web application is created to simulate situations of the use of computer-based devices for supporting clinical operations, involving 12 medical doctors and 3 patients. Two cases are analysed to demonstrate different situations of the web service. In such situations, stakeholders are requested to query patient information and specify the documents. The experiments have been evaluated by considering straightforward criteria to perform activities with the prototype to determine how accurate the documents are requested and specified, and evaluate how the health service performs efficiently.
