Assistive telehealth systems for neurorehabilitation
Telehealth is an evolving field within the broader domain of Biomedical Engineering, specifically situated within the context of the Internet of Medical Things (IoMT). In today's society, the importance of Telehealth systems is increasingly recognized, as they enable remote patient treatment by physicians. One significant application in neurorehabilitation is Transcranial Direct Current Stimulation (tDCS), which has demonstrated its effectiveness in modulating mental function and learning over several years. Furthermore, tDCS is widely accepted as a safe approach in the field. This presentation focuses on the development of a non-invasive wearable tDCS device with integrated Internet connectivity. This IoMT device enables remote configuration of treatment parameters, such as session duration, current level, and placebo status. Clinicians can remotely access the device and define these parameters within the approved safety ranges for tDCS treatments. In addition to the wearable tDCS device, a prototype web portal is being developed to collect performance data during neurorehabilitation exercises conducted by individuals at home. This portal also facilitates remote interaction between patients and clinicians. To provide a platform-independent solution for accessing up-to-date healthcare information, a Progressive Web Application (PWA) is being developed. The PWA enables real-time communication between patients and doctors through text chat and video conferencing. The primary objective is to create a cross-platform web application with PWA features that can function effectively as a native application in various operating systems
BCI controlled robotic arm as assistance to the rehabilitation of neurologically disabled patients
This presentation summarises the development of a portable and cost-efficient BCI controlled assistive technology using a non-invasive BCI headset 'OpenBCI' and an open source robotic arm, U-Arm, to accomplish tasks related to rehabilitation, such as access to resources, adaptability or home use. The resulting system used a combination of EEG and EMG sensor readings to control the arm, which could perform a number of different tasks such as picking/placing objects or assist users in eating
Atrial myxoma presenting as a cerebellar stroke
Primary tumors of the heart are rare. However, among them cardiac myxoma is the most common tumor accounting for half of the primary cardiac neoplasms. About 75% of cardiac myxomas are located in the left atrium, and 25% are located in the right atrium. These are thought to be arising from remnants of subendocardial vasoformative reserve cells or multipotential primitive mesenchymal cells in the fossa ovalis and surrounding endocardium, which can differentiate along a variety of cell lineages including epithelial, hematopoietic, and muscle cells. Although some cases are discovered incidentally by echocardiographic examination, it was recognized in most of the patients by various symptoms caused by the release of inflammatory cytokines such as interleukin-6 (IL-6), obstruction of intracardiac blood flow, or embolization. Cardiac myxoma has many undetermined interesting issues regarding its origin, nature as a tumor, varying clinical manifestations, and the presence of both sporadic and familial types. Recent evidence revealed that cardiac myxomas are benign neoplasms and slowly proliferating lesions. The existence of its malignant counterpart is controversial. However, recurrence after surgical excision or metastasis has been reported. We hereby present a case report of a young gentleman who presented with history of sudden onset of weakness and cerebellar signs. Urgent CT scan revealed hypodensities of bilateral occipital lobes and cerebellum suggestive of infarcts. Urgent echocardiography denoted large left atrial myxoma. The tumor was excised and the patient recovered well
Decomposition of Changes in Poverty Measures: Sectoral and Institutional Considerations for the Poverty Reduction Strategy Paper of Pakistan
Two extremely significant empirical questions on the relationship between growth, distribution and poverty have remained the focus of attention for researchers and academicians. First, how does a change in aggregate poverty reflect intrasectoral gains/losses versus intersectoral shifts in population? Second, how much of an observed change in poverty can be attributed to the changes in the distribution of income, as distinct from growth in average incomes? Standard inequality measures like the Gini coefficient can be misleading in this context. At any rate, the change in an inequality measure can be a poor guide to its quantitative impact on poverty. Ravallion and Huppi (1991) proposed decomposition formulae to throw light on the contributions of sectoral gains and population shifts (on the one hand) and economic growth and changes in inequality (on the other) to aggregate changes in poverty. They found that both population shifts and gains to the urban and rural sectors alleviated aggregate poverty in Indonesia over the 1984–87 period. In addition, they obtained estimates of the relative contributions of growth and greater equity to poverty alleviation in Indonesia. Datt and Ravallion (1992) extended the analysis to study poverty in Brazil and India during the 1980s. Kakwani (1993) explored the relation between economic growth and poverty for Cote d’Ivoire from 1980–85. He developed his own methodology to measure separately the impact of changes in average income and income inequality on poverty. Kakwani (2000) applied the same methodology to analyse changes in poverty in Thailand covering the period from 1988–94. Recently, Contreas (2003) examined the evolution of poverty and inequality in Chile between 1990 and 1996. Using the “Datt-Ravallion decomposition”, he computed that economic growth accounted for over 85 percent of the poverty reduction in Chile.
Forensic analysis of secure ephemeral messaging applications on Android platforms
Secure messaging applications have been used for the purposes of major crime, creating the need for forensic research into the area. This paper forensically analyses two secure messaging applications, Wickr and Telegram, to recover artefacts from and then to compare them to reveal the differences between the applications. The artefacts were created on Android platforms by
using the secure features of the applications, such as ephemeral messaging, the channel function and encrypted conversations. The results of the experiments documented in this paper give insight into the organisation of the data structures by both Wickr and Telegram, as well as the exploration of mobile digital forensics techniques to recover artefacts removed by the ephemeral functions
Aspek Pidana dalam Berita Bohong (Hoax) Menurut Fiqh Jinayah
The current world of information is changing rapidly. The more advanced the day, the faster. Positive impact for progress is certainly. But the negative excesses also need to be anticipated. One is the easy and fast news is not true or hoax spread. His excesses are noise, discomfort. Security becomes disrupted. Steps that can be taken include through legal steps. The legislation of the Republic of Indonesia has actually regulated it through UU ITE number 11 of 2008 amended by Act No. 19 of 2016. Article 28 juncto article 45 provides that anyone who disseminates misleading and SARA-related information is threatened with a six-year jail sentence and a fine maximum of one billion. The spread of false news in fiqh jinayah pertained as jarimah ta'zir which arrangement fully become the authority of ulil amri. Crime categories of hoax and sanctions have been aligned with the essence of Fiqh Jinayah
Hasil Belajar Kognitif IPA Fisika Melalui Penerapan Pendekatan Open-ended Poblem Pada Materi Cahaya Di SMPN 17 Pekanbaru
Abstrack: This research aimed to describe students learning result by applying approach open-ended problem. Type of this research is a pre-experimental, with intact-group comparison design. The population and sample of this research is students class VIII at SMPN 17 Pekanbaru, total of 240 students. Sample of this using two class with technik random sampling, experimental class and control class. The data in this research is a score of absorption and effectivity learning physics by implementation of approach open-ended problem and analysis of the data uses descriptive analysis. The result of this research, score absorption and effectivity of students there is a difference, score average absorption and effectivity is 74,5 % at experimental class and then 62 % at control class. Therefore, it can be concluded that the implementation approach open-ended problem able to improve the learning result of student at SMPN 17 Pekanbar
