Enhancing Road Traffic Safety in- Kenya Using Artificial Neural Networks

The world loses a human live in every 24 second due to Road Traffic Accidents (RTAs). In Kenya approximately 3000 lives are lost annually due to RTAs. The interventions to improve road traffic safety (RTS) failed because they were not informed by any scientific research. In this paper we employed the multi-layer feed forward perceptron neural network model to classify the road traffic safety status (RTSS) as:-excellent, fair, poor or danger states which model2019;s output are. We considered the vehicle internal factors that contribute to RTAs as model2019;s inputs which included:-inside-vehicle-condition, entertainment, safety-awareness, passager2019;s (attention, criminal-history, health-history, movement inside vehicle, body posture, frequency of journey, drunkenness2019;, drug-influence, use-of-mobile-phone and load), luggage-type and the safetybelt

Investigating Whether Consuming Meals in a Dining Room Impacts Patients’ Mood, Level of Interaction, and Subsequent Nutrient Intake in a Stroke Rehabilitation Ward.

Background/objectivesMalnutrition is evident in hospitals and stroke patients are at increased risk. Protected mealtimes may help increase nutrient intake especially when patients interact and enjoy the dining room atmosphere. The aim of this research is to investigate if eating in a communal dining room increases nutritional intake compared to eating at the bedside and to investigate whether patient interaction and mood affects patient nutrient intake. Population/methods:A randomised cross-sectional study of 20 patients, assessing a comparison of patient’s mealtime consumption at lunchtime in the dining room and at the beside. Patients’ meals were weighed before and after consumption as well as an estimated percentage of their meals consumed. Patients’ interaction was observed and noted using a modified case report form. The Hammond depression scale was used to score patients’ mood. Patient and staff satisfaction surveys were completed at the end of the study period. Results:There was no significant difference in protein and energy consumption in the dining room (16.4g protein and 379.2kcal) compared to at the bedside (13.2g protein and 333.8kcal), p=0.160 and p=0.110 respectively. Interaction was higher in the dining room. The percentage mealtime consumption increased the more interactive a patient was from a mean of 74% in less interactive patients to 98% in highly interactive patients (p=0.193). There was no significant association between depression score and mealtime consumption. All 19 patients enjoyed eating in the dining room and 14 out of the 19 patients preferred eating in the dining room. Conclusion:Further studies are required to explore how intake can be improved among stroke rehabilitation patients

A relevância do design de embalagem na relação da música com o usuário / The relevance of packaging design in the relationship between music and the user

Com o crescimento das mídias digitais, esperava-se que a música em formato físico, como CDs e vinis, fosse extinta, haja vista sua considerada queda em vendas na última década. Porém, nos últimos anos, foi registrado um aumento nas vendas de CDs, sendo o design de embalagem fator significativo para gerar os vínculos emocionais com os consumidores. Nesse contexto, o presente trabalho tem como objetivo mostrar a importância do design de embalagem na relação da música com o consumidor, auxiliando no desenvolvimento de uma relação mais profunda e criando diferenciações entre produções em suas versões digitais e físicas, estimulando o interesse dos consumidores que não percebiam motivos para adquirir produções em versão física e mantendo o interesse dos consumidores usuais. Um dos principais apontamentos deste trabalho foi a percepção de que a amostragem que consome versões físicas das produções comumente as faz pela influência do design em suas embalagens, tornando-as um produto valoroso, e não somente um meio de confiar a música em formato físico ao usuário. Mesmo as pessoas que por alguma razão não consomem as produções em versão física têm conhecimento sobre elas e exercem influência em sua percepção, destacando em suas lembranças os trabalhos que apresentam maior diferenciação e singularidade em seu design.

Using Co-Design to Discern and Overcome Barriers to Employment in Cape Town

In this paper we describe the co-design process to uncover the unemployment problem, in Cape Town, South Africa. We engage with unemployed or underemployed individuals at two different NGO sites in Cape Town. We engage, primarily with current and former students of two job readiness programmes and supplement our work with input from intermediary trainers. We outline our use of co-design under the umbrella of Participatory Design (PD) and discuss our findings, in line with the different documentations of benefits of intermediaries. Our findings highlight the benefits of working with intermediaries from the NGOs and the benefit of working with NGOs as embedded community partners. Additionally, we show that co-design can be used to successfully uncover issues around a problem such as unemployment

Live-cell imaging to detect phosphatidylserine externalization in brain endothelial cells exposed to ionizing radiation: Implications for the treatment of brain arteriovenous malformations

© 2016 AANS. Objective Stereotactic radiosurgery (SRS) is an established intervention for brain arteriovenous malformations (AVMs). The processes of AVM vessel occlusion after SRS are poorly understood. To improve SRS efficacy, it is important to understand the cellular response of blood vessels to radiation. The molecular changes on the surface of AVM endothelial cells after irradiation may also be used for vascular targeting. This study investigates radiation-induced externalization of phosphatidylserine (PS) on endothelial cells using live-cell imaging. methods An immortalized cell line generated from mouse brain endothelium, bEnd.3 cells, was cultured and irradiated at different radiation doses using a linear accelerator. PS externalization in the cells was subsequently visualized using polarity-sensitive indicator of viability and apoptosis (pSIVA)-IANBD, a polarity-sensitive probe. Live-cell imaging was used to monitor PS externalization in real time. The effects of radiation on the cell cycle of bEnd.3 cells were also examined by flow cytometry. results Ionizing radiation effects are dose dependent. Reduction in the cell proliferation rate was observed after exposure to 5 Gy radiation, whereas higher radiation doses (15 Gy and 25 Gy) totally inhibited proliferation. In comparison with cells treated with sham radiation, the irradiated cells showed distinct pseudopodial elongation with little or no spreading of the cell body. The percentages of pSIVA-positive cells were significantly higher (p = 0.04) 24 hours after treatment in the cultures that received 25-and 15-Gy doses of radiation. This effect was sustained until the end of the experiment (3 days). Radiation at 5 Gy did not induce significant PS externalization compared with the sham-radiation controls at any time points (p > 0.15). Flow cytometric analysis data indicate that irradiation induced growth arrest of bEnd.3 cells, with cells accumulating in the G2 phase of the cell cycle. coNclusioNs Ionizing radiation causes remarkable cellular changes in endothelial cells. Significant PS externalization is induced by radiation at doses of 15 Gy or higher, concomitant with a block in the cell cycle. Radiation-induced markers/targets may have high discriminating power to be harnessed in vascular targeting for AVM treatment

Reduced Performance of Prey Targeting in Pit Vipers with Contralaterally Occluded Infrared and Visual Senses

Both visual and infrared (IR) senses are utilized in prey targeting by pit vipers. Visual and IR inputs project to the contralateral optic tectum where they activate both multimodal and bimodal neurons. A series of ocular and pit organ occlusion experiments using the short-tailed pit viper (Gloydius brevicaudus) were conducted to investigate the role of visual and IR information during prey targeting. Compared with unoccluded controls, snakes with either both eyes or pit organs occluded performed more poorly in hunting prey although such subjects still captured prey on 75% of trials. Subjects with one eye and one pit occluded on the same side of the face performed as well as those with bilateral occlusion although these subjects showed a significant targeting angle bias toward the unoccluded side. Performance was significantly poorer when only a single eye or pit was available. Interestingly, when one eye and one pit organ were occluded on opposite sides of the face, performance was poorest, the snakes striking prey on no more than half the trials. These results indicate that, visual and infrared information are both effective in prey targeting in this species, although interference between the two modalities occurs if visual and IR information is restricted to opposite sides of the brain

Universal features of correlated bursty behaviour

Inhomogeneous temporal processes, like those appearing in human communications, neuron spike trains, and seismic signals, consist of high-activity bursty intervals alternating with long low-activity periods. In recent studies such bursty behavior has been characterized by a fat-tailed inter-event time distribution, while temporal correlations were measured by the autocorrelation function. However, these characteristic functions are not capable to fully characterize temporally correlated heterogenous behavior. Here we show that the distribution of the number of events in a bursty period serves as a good indicator of the dependencies, leading to the universal observation of power-law distribution in a broad class of phenomena. We find that the correlations in these quite different systems can be commonly interpreted by memory effects and described by a simple phenomenological model, which displays temporal behavior qualitatively similar to that in real systems

Feasibility and validity of International Classification of Diseases based case mix indices

BACKGROUND: Severity of illness is an omnipresent confounder in health services research. Resource consumption can be applied as a proxy of severity. The most commonly cited hospital resource consumption measure is the case mix index (CMI) and the best-known illustration of the CMI is the Diagnosis Related Group (DRG) CMI used by Medicare in the U.S. For countries that do not have DRG type CMIs, the adjustment for severity has been troublesome for either reimbursement or research purposes. The research objective of this study is to ascertain the construct validity of CMIs derived from International Classification of Diseases (ICD) in comparison with DRG CMI. METHODS: The study population included 551 acute care hospitals in Taiwan and 2,462,006 inpatient reimbursement claims. The 18(th )version of GROUPER, the Medicare DRG classification software, was applied to Taiwan's 1998 National Health Insurance (NHI) inpatient claim data to derive the Medicare DRG CMI. The same weighting principles were then applied to determine the ICD principal diagnoses and procedures based costliness and length of stay (LOS) CMIs. Further analyses were conducted based on stratifications according to teaching status, accreditation levels, and ownership categories. RESULTS: The best ICD-based substitute for the DRG costliness CMI (DRGCMI) is the ICD principal diagnosis costliness CMI (ICDCMI-DC) in general and in most categories with Spearman's correlation coefficients ranging from 0.938-0.462. The highest correlation appeared in the non-profit sector. ICD procedure costliness CMI (ICDCMI-PC) outperformed ICDCMI-DC only at the medical center level, which consists of tertiary care hospitals and is more procedure intensive. CONCLUSION: The results of our study indicate that an ICD-based CMI can quite fairly approximate the DRGCMI, especially ICDCMI-DC. Therefore, substituting ICDs for DRGs in computing the CMI ought to be feasible and valid in countries that have not implemented DRGs
