Resumen Se describen 39 brotes de enfermedades transmitidas por alimentos que afectaron a 958 perso- nas en la provincia de Rio Negro, Argentina, en el periodo 1993- 2001. Se identifican los agentes causales, los alimentos involucrados, los sitios de ocurrencia, los factores de riesgo involucrados y los meca- nismos de notificacion empleados. Salmonella spp (38%), Trichinella spiralis (15%), Escherichia coli (13%) y Staphylococcus aureus (15%) resultaron los agentes mas frecuentes en los brotes. Salmonella spp. tambien produjo el mayor numero de casos (52%). Los principales alimentos involucrados resultaron carneos (36%), quesos (10%), fiambres y sandwiches (10%), postres (10%) y helados (8%). El mayor numero de casos, por su parte, fue causado por la ingestion de helados (37%). Con relacion al origen de los alimentos, 41% de los bro- tes fueron causados por comidas elaboradas en los domicilios, 23% en establecimientos comerciales, 13% en fiestas familiares, 8% en fiestas comunitarias y 8% en restaurantes de hoteles. En el 28% de los brotes fue identificado el agente etiologico por analisis epidemiologico exclusivamente, en el 64% se logro el aislamiento del agente, mientras que en el 8% de los casos no se logro el diagnostico definitivo. Se analiza el valor de la encuesta epidemiologica en los estudios de enfermedades transmitidas por alimentos, la necesidad de fortale- cer el sistema de notificacion medica de casos y brotes y la importancia de las buenas practicas en la manipu- lacion de alimentos. Palabras clave: enfermedad transmitida por alimentos, brotes, vigilancia epidemiologica Abstract Surveillance of foodborne diseases in the Province of Rio Negro, Argentina, 1993 - 2001. A total of 39 outbreaks of foodborne diseases affecting 958 people in the province of Rio Negro, Argen- tina between 1993 and 2001 are described and evaluated. The main causal agents were identified involving food, sites of occurrence, risk factors and notification system used. Salmonella spp (38%), Trichinella spiralis (15%), Escherichia coli (13%) and Staphylococcus aureus (15%) were the most frequent agents present in outbreaks. Salmonella spp produced the largest number of cases (52%). Food involved were cooked meat (36%), cheese (10%), sandwiches (10%), deserts (10%) and ice cream (8%). Indeed, ice creams were involved in the largest number of cases and of people affected. In relation to the source of food, 41% of outbreaks were caused by homemade meals, 23% by catering or ice cream parlor, 13% in family parties, 8% in county fairs and 8% in hotel restaurants. In 28% of the outbreaks the etiological agent was identified exclusively by epidemiological analysis, in 64 % isolation of the agent was carried out, and in 8% of the cases, a final diagnosis could not be obtained. Validity of epidemiological studies in foodborne disease, the necessity of strengthening the notifi- cation system of outbreaks, and the importance of good practices in food handling are analyzed.
A rotation-invariant embedded pattern recognition system

Hardware implementations of neural networks (NN) offer superior performance over software implementations due to the inherent parallelism that can be exploited at the architectural level. However, they are rendered unsuitable for incorporation into low-cost pattern recognition systems, as they are expensive to implement in VLSI. This paper proposes a rotation-invariant embedded pattern recognition system based on an area-efficient NN architecture. It employs a novel feedforward multi-layered, time-multiplexed neural network architecture with multi-level threshold functions. Novel training and recall methods that best exploit this architecture have also been devised. Our results show that the proposed method exhibits superior learning and recognition abilities, and also tends itself well to a low-cost rotation-invariant pattern recognition system. Such a system can be used effectively for different industrial applications that involve machine vision or autonomous mobile robots.
The Aesthetics of Viruses

The aesthetics of viruses is worthy of investigation even if these organisms represent a potential hazard for the health and life of living beings. The extracellular virus (virion) is a ‘monumental’ product of nature in that it contains a vast amount of information in its clear, concise and puritanic structure. In this paper, structures produced by evolutionary processes are compared and contrasted with those designed by humans. It is noted that discoveries in geometry and architecture have had beneficial influence on research on viruses, and vice versa.

A VLSI architecture for real-time image convolution with large symmetric kernels

The authors propose VLSI architectures for real-time convolution of an image by any large kernel with symmetries. Consideration is limited to horizontal, vertical, and central symmetries in order to reduce the hardware requirements. Based on these architectures, a chip is proposed which would implement a real-time convolution of 512*512 images with kernels up to 11*11 and allow online processing of video format images. <<ETX>>
Formulating foster care in Scotland for young children's emotional and mental wellbeing (short report)

Foster carers can play a key role in supporting a child’s recovery from abuse and neglect and improving their mental health, but optimising this requires appropriate formulation of the care arrangements. This is a report on a scoping study into the extent to which the way foster care as conceived and supported, provides the basis for meeting the emotional and mental health needs of young children. It focuses on children aged up to 60 months who have been removed from their parents’ care because of maltreatment, or risk of maltreatment and who have been placed in state provided (non-familial) foster care provision in Scotland. The project had three main objectives: 1. To establish what is known about the emotional and mental health needs of young children (aged zero to five years) coming into the care system. 2. To look at the preparation and support for foster carers in Scotland relevant to caring for these children, through analysis of local authority documents. 3. To explore the experience of foster carers in meeting the emotional and mental health needs of children, through interviews with a sample of foster carers.
Speaker adaptation for large vocabulary speech recognition systems using speaker Markov models

An alternative approach to speaker adaptation for a large-vocabulary hidden-Markov-model-based speech recognition system is described. The goal of this investigation was to train the IBM speech recognition system with only five minutes of speech data from a new speaker instead of the usual 20 minutes without the recognition rate dropping by more than 1-2%. The approach is based on the use of a stochastic model representing the different properties of the new speaker and an old speaker for which the full training set of 20 minutes is available. It is called a speaker Markov model. It is shown how the parameters of such a model can be derived and how it can be used for transforming the training set of the old speaker in order to use it in addition to the short training set of the new speaker. The adaptation algorithm was tested with 12 speakers. The average recognition rate dropped from 96.4% to 95.2% for a 5000-word vocabulary task. The decoding time increased by a factor of 1.35; this factor is often 3-5 if other adaptation algorithms are used. <<ETX>>
Scalp--in search of the perfect donor site.

: In many cases where a wound to be grafted is large, particularly in burns, the patient's condition may be aggravated by exposed donor sites. Adding thigh or even buttock scars to a patient must be carefully considered. The scalp, it appears, is a safe, reliable, and truly hidden donor site. For this and other reasons mentioned, its use should be promoted in plastic surgery.
FGFR1 et MOZ, deux gènes clés dans les hémopathies malignes associées à des réarrangements de la région chromosomique 8p11-12

Two distinct clinical syndromes have been associated with the p11.12 region of the short arm of chromosome 8: stem-cell myeloproliferative disorder (B-or T-cell lymphoblastic leukemia/lymphoma with myeloid hyperplasia and peripheral blood eosinophilia) and acute myeloid leukemia (myelomonocytic or monocytic with erythrophagocytosis). The FGFR1 and MOZ genes are rearranged in these diseases and encode one of the four fibroblast growth factor receptors and a member of a novel histone acetyltransferase family, respectively. The predicted fusion proteins that are putatively oncogenic - FOP-FGFR1, CEP110-FGFR1, and FIM-FGFR1 - and - MOZ-CBP, MOZ-p300, and MOZ-TIF2 - lead to tumorigenesis through distinct pathways. The constitutive kinase activity triggered by dimerization mediated by the protein-protein interaction motifs of the FGFR1 protein partner regardless of external stimuli and the delocalization of the fusion proteins compared to their normal counterparts may lead to tumorigenesis presumably by inducing inappropriate recruitment in the cytoplasm of signaling substrates. Currently, little is known about the precise role of MOZ in the regulation of gene transcription. However, all the aberrant proteins described to date retain the MOZ histone acetyltransferase domain fused to that of the transcription coactivators CBP, p300, and TIF2. The fusion of two acetyltransferases whose activity may be mistargetted or misregulated could be a critical event in leukemogenesis. The increasing number of translocations affecting FGFR1 and MOZ strongly suggest their involvement in oncogenic processes and point to these proteins as potential therapeutical targets.
Frequent Patterns Discovery in Complex Structured Data with Higher-Order Logic

Frequent patterns mining is one of the most important tasks in data mining, traditional algorithms usually deal with this problem in simple structured data, but there are so much complex data in reality, for example, the tree type of data, graph type of data, and so on, when investigating these complex structured data, constrains are often needed to be given in order to narrow the search space, however, this will lose some of the useful interesting patterns. In this paper, we present a novel algorithm based on higher-order logic to discover frequent patterns in complex structured data, the novel method can overcome some drawbacks occurring in traditional algorithms. We use Escher, which is a higher-order logic programming language, to discover frequent patterns in complex structured data. Experimental results show that the proposal algorithm is efficient and scalable.
Optimal acknowledgement strategies for multichannel reservation multi-access schemes under Rayleigh fading

A reservation-based medium access control (MAC) scheme is considered where users reserve data channels through a slotted-ALOHA procedure. The base station grants access to users in a Rayleigh fading environment using detectors that utilize measurements at the physical layer and system information at the MAC layer. The performance analysis is based on a Markov chain formulation and optimal performance obtainable in the given scenario is evaluated. An acknowledgement strategy based on cost-optimized Bayesian detectors which achieves this optimal performance is presented along with strategies based on other detectors such as MAP, ML and UMP. The delay/channel-utilization trade-off is considered for various system parameters.
Dependency analysis tools: reusable components for software maintenance

A general-purpose toolset that is being developed to capture and analyze software dependencies is described. The tools are designed to serve as reusable components. They can be used not only to aid programmers directly in understanding programs but also as a basis from which other specialized tools can be constructed. The tools use the concept of a dependency graph as a basic abstraction to simplify the understanding of software relationships. Definitional, calling, functional and data-flow dependencies are analyzed. An external dependency graph for each function is developed to encapsulate the effects of function cells. <<ETX>>
Ordonnancement des instructions pour un processeur ARM endochrone

Les processeurs endochrones, par definition, utilisent des mecanismes locaux de synchronisation leur permettant de s’affranchir du maintien d’un signal d’horloge globale. Cette specificite les rend moins energivores comparativement aux processeurs synchrones. Toutefois, les processeurs endochrones sont moins populaires en raison du manque d’outils de design et de verification ainsi que l’evolution rapide des processeurs synchrones en terme de performance. Ce memoire s’inscrit dans le cadre du projet AnARM visant a developper un processeur a usage general ARM base sur une architecture endochrone. Ce memoire vise plus particulie-rement l’exploration des methodes d’ordonnancement des instructions pour developper une strategie d’ordonnancement, basee sur les caracteristiques architecturales de l’AnARM, dans le but d’en ameliorer les performances. L’ordonnancement des instructions est une optimisation du compilateur ayant un grand impact sur la qualite du code genere. Cette optimisation consiste a resoudre un probleme NP-complet en tenant compte des contraintes imposees par l’architecture du processeur cible. Tandis que l’ordonnancement des instructions pour les architectures synchrone beneficie d’une large couverture litteraire, l’ordonnancement pour les architectures asynchrones a ete moins aborde, en raison des nouvelles contraintes imposees par les mecanismes de synchronisation utilisees par ces architectures. Ce memoire presente l’elaboration, l’implementation et l’evaluation d’une strategie d’ordonnancement pour le processeur endochrone AnARM. La methode d’ordonnancement presentee dans ce memoire utilise un modele d’ordonnancent dynamique base sur le comportement spatio-temporel de l’AnARM. Cette methode a ete implementee au sein d’un compilateur commercial moderne et evaluee comparativement a des methodes d’ordonnancement usuelles. La methode d’ordonnancement presentee dans ce memoire engendre des ameliorations de la performance allant de 6,22% a 17,48%, tout en preservant l’avantage energetique de l’architecture endochrone a l’etude.

The Impact of Prophylactic Salpingo-oophorectomy on Health in Women who carry a BRCA1 or BRCA2 Mutation

Prophylactic salpingo-oophorectomy, the preventive removal of the ovaries and fallopian tubes, is recommended to women who carry a BRCA1 or BRCA2 mutation in order to reduce the risk of breast, ovarian and fallopian tube cancer. The short and long term health and quality of life effects of this procedure are not well understood. We examined the actual and perceived reduction in cancer risk associated with this surgery. The impact of prophylactic salpingo-oophorectomy on health-related quality of life, psychological distress, cancer worry, menopausal symptoms, and sexual function during the year following surgery was also evaluated. In our prospective study, prophylactic salpingo-oophorectomy was associated with an 80% reduction in ovarian and fallopian tube cancer risk. The residual risk for primary peritoneal cancer was 0.2% per year or 4.3% at 20 years after salpingo-oophorectomy. Most women accurately perceived their risk of breast cancer. However, the risk for ovarian cancer was overestimated, particularly by women who carry a BRCA2 mutation. Physical and mental health-related quality of life did not decrease in the year following surgery; and psychological distress was similar to levels experienced by the general population. Most women were significantly less worried about cancer after the surgery, however, a subset of women continued to experience significant cancer specific distress after prophylactic salpingo-oophorectomy. Women who underwent prophylactic salpingo-oophorectomy when premenopausal experienced a significant worsening of vasomotor symptoms and a decline in sexual functioning. Hormone replacement therapy mitigated these symptoms, but not to pre-surgical levels. Dyspareunia was somewhat alleviated by hormone replacement therapy, however, the decrease in sexual pleasure was not. Satisfaction with the decision to undergo prophylactic salpingo-oophorectomy was high regardless of these symptoms. These studies will provide women who are considering prophylactic salpingo-oophorectomy with information about the reduction in cancer risk associated with the surgery and the possible effects experienced during the year following surgery.

O uso de elementos sensoriais no ponto de venda aumenta os índices de atratividade, lealdade e preferência dos shoppers à loja?: uma reflexão crítica

O presente trabalho analisa a influencia do marketing sensorial aplicado ao ponto de venda na melhoria dos indices de atratividade, lealdade e preferencia dos shoppers a loja. O marketing experimental tem ganhado relevância em funcao da maior concorrencia entre os canais de compra fisicos e da disputa destes com o canal virtual, que oferece maior conveniencia e, em alguns casos, melhores precos. Ha que se levar em consideracao que os shoppers estao sobrecarregados de estimulos visuais e que tendem a responder melhor a estimulos que envolvam mais de um sentido. Esta dissertacao e um estudo de caso multiplo que visa comparar os indices de lealdade e preferencia de dois hipermercados da rede Carrefour, um com conceito tradicional e outro com conceito Planet. O Carrefour Planet e uma tentativa do Grupo Carrefour de reestruturar o hipermercado, atraves de centros de solucoes de compra, no qual cada departamento transmite uma atmosfera diferenciada e centrada na exploracao de seus principais itens e elementos sensitivos, pois os hipermercados tem encontrado dificuldades de se diferenciar ante os demais canais. Apesar dos esforcos do Carrefour em diferenciar o hipermercado, e possivel concluir do presente trabalho que a gestao sensorial do ponto de venda nao trouxe aumento nos indices de lealdade e preferencia dos shoppers quando comparadas a loja Planet e a loja Carrefour tradicional, embora a loja Planet tenha sobressaido como a mais atrativa. Recomenda-se o desenvolvimento de estudos futuros que comparem os indices de lealdade e preferencia de um mesmo ponto de venda (antes e apos o uso de elementos sensitivos)
