Human motion reconstruction fom video sequences with MPEG-4 compliant animation parameters.

The ability to track articulated human motion in video sequences is essential for applications ranging from biometrics, virtual reality, human-computer interfaces and surveillance. The work presented in this thesis focuses on tracking and analysing human motion in terms of MPEG-4 Body Animation Parameters, in the context of a model-based coding scheme. Model-based coding has emerged as a potential technique for very low bit-rate video compression. This study emphasises motion reconstruction rather than photorealistic human body modelling, consequently a 3-D skeleton with 31 degrees-of-freedom was used to model the human body. Compression is achieved by analysing the input images in terms of the known 3-D model and extracting parameters that describe the relative pose of each segment. These parameters are transmitted to the decoder which synthesises the output by transforming the default model into the correct posture. The problem comprises two main aspects: 3-D human motion capture and pose description. The goal of the 3-D human motion capture component is to generate 3-D locations of key joints on the human body without the use of special markers or sensors placed on the subject. The input sequence is acquired by three synchronised and calibrated CCD cameras. Digital image matching techniques including cross-correlation and least squares matching are used to find spatial correspondences between the multiple views as well as temporal correspondences in subsequent frames with sub-pixel accuracy. The tracking algorithm automates the matching process examining each matching result and adaptively modifying matching parameters. Key points must be manually selected in the first frame, following which the tracking commences without the intervention of the user, employing the recovered 3-D motion of the skeleton model for prediction of future states.

Experience of employment of computational models for water quality modelling

The purpose of the article is to develop the required and sufficient conditions under which numerical methods can be used for engineering calculations and for scientific research of hydrodynamic processes in solving practical problems related to predicting the spread of pollutants in water bodies and streams. The conducted studies consisted in comparing the results of laboratory experiments and mathematical modelling, in particular the distribution of heat in a stream with different temperature in water layers was studied. To check the adequacy of the proposed numerical models, calculations were performed and comparisons were made with the results of experimental data. The obtained results allowed to determine the boundaries of the qualitative difference in the flow behaviour for different numbers of Froude and Reynolds. The accuracy of the method was also studied. A number of additional requirements for numerical models were proposed in addition to approcsimation and stability, such as requirements of conservativeness (divergence), existence of trivial solutions on grids, possibility to calculate highly unsteady, quasi-stable, pulsating and stationary flows, requirement of invariance of linearized equations, as well as the requirement of a one-dimensional scheme to be a consequence of a two-dimensional scheme. Distribution of velocities of wind currents using a three-dimensional and two-dimensional model was studied for a real object. A shallow-water bay of the Aral Sea was chosen as the object for the research. Comparison of the calculation results for both models showed that the flow velocity fields, as well as the distribution of pollutants in shallow waters, can be performed using a two-dimensional model.
Determinants of Non-Adherence to Antiretroviral Therapy and Modeling Progression of Adherence Level: At Yirgalem Regional Hospital, Ethiopia; January, 2012

Non-adherence is a global problem and has been seen in all diseases. According to WHO, adherence to long-term therapies in chronic illnesses averages 50% in developed countries? Adherence to HAART is challenging, because patients need almost perfect adherence of at least 95 percent to keep viral load at undetectable levels as long as possible and maintain the functionality of the immune system. Poor adherence to antiretroviral therapy increases the risk of incomplete viral suppression, disease progression and death. The purpose of this study was to assess the level and factors associated with non-adherence to antiretroviral therapy. A random sample of 368 patients were taken from the ART clinic at Yirgalem Regional Hospital from September 2006 to July 2011.Adherence levels were measured using methods pill count, pill identification test, and self-report. Descriptive statistics and both Bivariate and multivariate Logistic Regression were used to analyzed the data. Homogeneous Semi-Markov Stochastic Model was used to reveal the conditional probability of staying in non-adherence. The Multivariate Logistic Regression Method showed that the gender (sex), family size, social support available to the patients, ART knowledge of the patients, time on ART in month, and baseline CD4 counts/mm3 were significant factors associated with non-adherence to ART medications. The conditional probability of staying in non-adherence, until a given time in month was higher than staying in adherence. Thus, it is suggested that health-care providers need to be watchful about adherence levels of patients. Specifically males, who have been on ART for several months, living in large family members, lack of social support, having high baseline CD4 counts/mm3, and having poor knowledge of ART.
Designing and researching technology-enhanced learning for the zone of proximal implementation

Internationally, society is increasingly demanding that the relevance and practical applicability of research be made transparent. Despite intentions to the contrary, insights on pedagogically appropriate uses of educational technology for representative teachers in everyday school settings are severely limited. In part, this is because (design) research is often conducted at the bleeding edge of what is technologically possible – exploring innovative uses of new and emerging technologies. There is no disputing that such work is greatly needed to seek out new ways to potentially enhance the quality of teaching and learning. However, in the excitement of exploring what is possible, tomorrow, insufficient research and development work focuses on what is practical, today. This leaves a problematic gap between what could be effective technology-enhanced learning (TEL) in theory, and what can be effective TEL in practice. This paper calls for designers/researchers of TEL to devote attention to not only fine-grained issues of pupil learning and instruction but also to broader factors that determine if and how innovations are understood, adopted and used by teachers and schools, by designing innovations to align with their zone of proximal implementation . Methodological considerations are given for designing and studying interventions that are prone to implementation by being: value-added, clear, harmonious and tolerant. Keywords: learning design; implementation; innovation (Published: 16 September 2013) Citation: Research in Learning Technology Supplement 2013, 21 : 17374 - http://dx.doi. org/10.3402/rlt.v21i0. 17374
Usefulness of recurrence and progression nomograms in Mexican bladder cancer patients

Introducción: Los factores pronóstico en pacientes con cáncer superficial de vejiga han sido un tema de controversia y motivo de varias publicaciones a lo largo de los años. Actualmente, la cistoscopia y las citologías urinarias representan el gold standard para la vigilancia del carcinoma de células transicionales. Sin embargo, la cistoscopia representa un estudio de alto costo, molestias para el enfermo y la posibilidad de complicaciones tales como infección o trauma. Material y métodos: Revisamos los expedientes de todos los pacientes con cáncer superficial de vejiga de entre enero de 1990 a enero de 2007. El análisis estadístico se realizó con medidas de tendencia central y de dispersión: rango, media, mediana, moda, desviación estándar, proporciones o porcentajes. Resultados: Se analizaron 70 pacientes con diagnóstico de cáncer superficial de vejiga, de los cuales 60 cumplieron con criterios de inclusión: 44 (73%) hombres y 16 (26.6%) mujeres, con rangos de edad de entre 19 a 91 años, media de 59.2.
Working for Food

ABSTRACT One of the duties medical librarians are supposed to carry out is teaching people how to use medical information services. However, many of us limit that teaching to within library walls. This article relates how one librarian has expanded his audience to physicians at small, rural hospitals and some of the challenges and benefits to “working for food. ”

Why Do Employees Keep Choosing the Expensive Health Care Plan? An Investigation of the Quality and Logic of Employee Health Care Plan Selections

In 1991, The Dannon Company provided 287 of its employees with a choice of healthcare plans. The new plan was less expensive and designed to fit employees' needs better. Contrary to managerial expectation, threequarters of employees continued to choose the more expensive plan. To study why this was occurring and to determine if these choices reflected employee "mistakes," a cooperative effort was begun between The Dannon Company and Cornell University. This cooperative effort allowed us to investigate this problem using actual employee medical claims. Analysis revealed employees strive not only to minimize costs, but also to avoid risk in their health care plan decisions. Overall, employees with the most significant cost difference chose the plan with the lowest total costs. This effect translated into financial savings for the employees. Employees were better off as a group with the freedom to make their own selections than they would have been if they had been forced into either of the two available health care options. Thus, this study demonstrated that choice is valuable to employees. Implications for Dannon and for future research are discussed.

Introduction : L'electro-cardiographie permet de faire une etude de la morphologie et des variations electriques du muscle cardiaque. Tandis que l'echographie est une methode qui etudie surtout les structures anatomiques et l'etat fonctionnel du coeur. Le doppler par contre donne la mesure des differents gradients de pression des flux intracardiaques. Justifications : Nous voulons verifier les differents parametres que ce soit a l'ECG qu'a l'echo-cardio-doppler chez le sportif de haut niveau. Methodes et resultats : L'etude porte sur 100 athletes de haut niveau pratiquant soit un sport de type isotonique soit de type isometrique. Dans les sports de type isotonique, on note une bradycardie sinusale avec quelquefois un bloc auriculo-ventriculaire du 1er au 2eme degre. L'echographie precise une augmentation a la fois du diametre telediastolique du VG et du septum inter-ventriculaire de la paroi posterieure. Dans les sports de type isometrique, on note de meme la bradycardie sinusale, l'hypertrophie septale ou de la paroi posterieure Dans tous les cas, le Doppler montre une insuffisance mitrale ou tricuspidienne fonctionnelles ou les deux associees. Conclusion : L'ECG et l'echo-doppler cardiaque contribuent avec la clinique a la visite d'aptitude et a la surveillance des sportifs de haut niveau.
Oral care after stroke: Where are we now?

Purpose There appears to be an association between poor oral hygiene and increased risk of aspiration pneumonia – a leading cause of mortality post-stroke. We aim to synthesise what is known about oral care after stroke, identify knowledge gaps and outline priorities for research that will provide evidence to inform best practice. Methods A narrative review from a multidisciplinary perspective, drawing on evidence from systematic reviews, literature, expert and lay opinion to scrutinise current practice in oral care after a stroke and seek consensus on research priorities. Findings: Oral care tends to be of poor quality and delegated to the least qualified members of the caring team. Nursing staff often work in a pressured environment where other aspects of clinical care take priority. Guidelines that exist are based on weak evidence and lack detail about how best to provide oral care. Discussion Oral health after a stroke is important from a social as well as physical health perspective, yet tends to be neglected. Multidisciplinary research is needed to improve understanding of the complexities associated with delivering good oral care for stroke patients. Also to provide the evidence for practice that will improve wellbeing and may reduce risk of aspiration pneumonia and other serious sequelae. Conclusion Although there is evidence of an association, there is only weak evidence about whether improving oral care reduces risk of pneumonia or mortality after a stroke. Clinically relevant, feasible, cost-effective, evidence-based oral care interventions to improve patient outcomes in stroke care are urgently needed.
Nursing handoffs: ensuring safe passage for patients.

Handoffs serve many functions, from social bonding, to coaching and teaching, to team building, but the most important function of handoffs is information processing: making sure that essential data are transferred for patient safety. Substandard or variable handoffs have contributed to errors, care omissions, treatment delays, inefficiencies from repeated work, inappropriate treatment, adverse events with minor or major harm, increased length of stay, avoidable readmissions, and increased costs. The Institute of Medicine reported that communication failures account for most adverse outcomes in hospitals. Indeed, communication breakdowns were the primary root cause of more than 60% of 2000 sentinel events analyzed by the Joint Commission. In 2006, the Joint Commission released a National Patient Safety Goal aimed at improving the effectiveness of communication among caregivers. Specifically, this goal required organizations to implement a standardized approach to communication during handoffs, incorporating an opportunity for staff to ask and respond to questions. A handoff is the “transfer and acceptance of responsibility for patient care that is achieved through effective communication. It is a real-time process of passing patient-specific information from one caregiver to another or from one team of caregivers to another to ensure the continuity and safety of that patient’s care. ” Recognized as points of vulnerability, handoffs occur within and across clinical settings and disciplinary boundaries—on units at changeof-shift and to accommodate breaks, as well as when patients transfer between units or are transported to or from other departments for tests or procedures.

Reliable and Privacy-Preserving Truth Discovery for Mobile Crowdsensing Systems

Truth discovery has received considerable attention in mobile crowdsensing systems. In real practice, it is vital to resolve conflicts among a large amount of sensory data and estimate the truthful information. Although truth discovery has been widely explored to improve aggregation accuracy, numerous security and privacy issues still need to be addressed. Existing schemes either do not guarantee the privacy of each participating user, or fail to consider practical needs in crowdsensing systems. In this paper, we present two reliable and privacy-preserving truth discovery schemes for different scenarios. Our first design is fit for applications where users are relatively stable. By employing the homomorphic Paillier encryption, one-way hash chain, and super-increasing sequence techniques, this approach not only guarantees strong privacy, but also is highly efficient and practical. Our second design suits applications where users are frequently moving. In such an application, we explore data perturbation and homomorphic Paillier encryption to shift all user workloads to the server side, without compromising users’ privacy. Through detailed security analysis, we demonstrate that both schemes are secure, practical, and privacy-preserving. Moreover, extensive experiments based on real world and simulated mobile crowdsensing systems, we demonstrate the efficiency of our proposed schemes.
STEM intervention strategies: Sowing the seeds for more women in STEM

Context: In a new study released by the Office of the Chief Scientist (2016), only 16% of Australians in Science, Technology, Engineering and Mathematics (STEM) professions are women. A better understanding of the motivations of, influences on, and barriers to young girls as they form STEM career aspirations, and the implementation of such knowledge towards targeted strategies, may improve the global gender disparity in STEM disciplines. A healthy and diverse STEM pipeline could lead to new perspectives on innovation, creativity, leadership and success, ultimately impacting the world's performance and productivity. Purpose: The purpose of this research is to identify barriers to girls at secondary school entering STEM careers, to propose recommendations for tackling and removing the perceived barriers and to identify methods to tailor existing outreach activities to better attract more female students. Approach: The opinions of 496 girls aged between 12 and 18 from an independent girls' school were gathered via an online survey. Results were used to inform strategies to improve the gender disparity in STEM disciplines via outreach activities, programs and marketing material. Results: While gender stereotypes, a lack of female role models and negative imagery associated with STEM are still frequently highlighted in the extensive body of literature as a cause for the underrepresentation of women in STEM fields, less than 10% of students in our context supported these claims. The perceived difficulty of STEM subjects and a lack of information surrounding STEM career pathways were identified as the dominant barriers to the uptake of STEM subjects. Furthermore, parents were clearly identified as the key influencers on children's academic and career trajectories. Conclusions: Tailored workshop activities and outreach materials that clearly highlight stimulating and diverse STEM career opportunities that are available through the pursuit of highly achievable STEM subjects, in addition to accompanying workshop materials designed for family members, could be key to improving the global gender disparity in STEM disciplines. Future studies with students from more diverse types and demographics of schools should be performed to ascertain if these results are anomalous or signal a wider change in student perceptions of STEM from the wider literature.
