  1. User-centered design

    International Nuclear Information System (INIS)

    The simplification philosophy, as an example, that both of EPRI-URD and EUR emphasize is treated mostly for the cost reduction of the nuclear power plants, but not for the simplification of the structure of user's tasks, which is one of the principles of user-centered design. A user-centered design is a philosophy based on the needs and interests of the user, with an emphasis on making products usable and understandable. However, the nuclear power plants offered these days by which the predominant reactor vendors are hardly user-centered but still designer-centered or technology-centered in viewpoint of fulfilling user requirements. The main goal of user-centered design is that user requirements are elicited correctly, reflected properly into the system requirements, and verified thoroughly by the tests. Starting from the user requirements throughout to the final test, each requirement should be traceable. That's why requirement traceability is a key to the user-centered design, and main theme of a requirement management program, which is suggested to be added into EPRI-URD and EUR in the section of Design Process.

    2013-01-01

    Agile development methods began to emerge around 20 years ago. However, it was not until the early 2000s that they began to be widely used in industry. This growth was often due to the advent of Internet services requiring faster cycles of development in order to heighten the rate at which an ever-greater number of functionalities were made available. In parallel, user-centered design (UCD) methods were also becoming more and more widely used: hence, user-centered design and agile methods were bound to cross paths, at least in the telecoms industry! During this period, in the field of telec

    Full Text Available Personalization and effective user profile management will be critical to meet the individual users’ needs and for achieving e-Inclusion and e-Accessibility. This paper outlines means to achieve the goal of the new ICT era where services and devices can be personalized by the users in order to meet their needs and preferences, in various situations. Behind every instance of personalization is a profile that stores the user preferences, context of use and other information that can be used to deliver a user experience tailored to their individual needs and preferences. Next Generation Networks (NGN and the convergence between telephony and Internet services offer a wide range of new terminal and service definition possibilities, and a much wider range of application in society. This paper describes the personalization and profile management activities at European Telecommunications Standards Institute (ETSI Technical Committee Human Factors, together with relevant experimentations in recent European research projects.

    The transfer of knowledge in an ecotourism project is never a one-way affair. An approach connected to bottom-up development is the submersion into another culture, while creating a new organizational structure. For co-creation, patterns that are often latent, such as leadership roles, the association with business, or even the color of education can be revealed by carefully facilitated brainstorms or workshops. Especially in countries with a different hierarchical structure, such as Indonesia compared to Holland, a careful analysis is needed before starting cooperation. Although a case is only a temporary view on a situation and not a guarantee for a truly sustainable system, the bottom-up approach tested has interesting starting points for an ecotourism system. Two cases were conducted in Bali, Indonesia, which resulted in guidelines on how to approach user-centered ecotourism development.

  8. Profiling users in the UNIX os environment

    Dao, V N P; Vemuri, R; Templeton, S J

    2000-09-29

    This paper presents results obtained by using a method of profiling a user based on the login host, the login time, the command set, and the command set execution time of the profiled user. It is assumed that the user is logging onto a UNIX host on a computer network. The paper concentrates on two areas: short-term and long-term profiling. In short-term profiling the focus is on profiling the user at a given session where user characteristics do not change much. In long-term profiling, the duration of observation is over a much longer period of time. The latter is more challenging because of a phenomenon called concept or profile drift. Profile drift occurs when a user logs onto a host for an extended period of time (over several sessions).

    Full Text Available User profiling is a useful primitive for constructing personalised services, such as content recommendation. In the present paper we investigate the feasibility of user profiling in a distributed setting, with no central authority and only local information exchanges between users. We compute a profile vector for each user (i.e., a low-dimensional vector that characterises her taste via spectral transformation of observed user-produced ratings for items. Our two main contributions follow: (i We consider a low-rank probabilistic model of user taste. More specifically, we consider that users and items are partitioned in a constant number of classes, such that users and items within the same class are statistically identical. We prove that without prior knowledge of the compositions of the classes, based solely on few random observed ratings (namely O(N log N such ratings for N users, we can predict user preference with high probability for unrated items by running a local vote among users with similar profile vectors. In addition, we provide empirical evaluations characterising the way in which spectral profiling performance depends on the dimension of the profile space. Such evaluations are performed on a data set of real user ratings provided by Netflix. (ii We develop distributed algorithms which provably achieve an embedding of users into a low-dimensional space, based on spectral transformation. These involve simple message passing among users, and provably converge to the desired embedding. Our method essentially relies on a novel combination of gossiping and the algorithm proposed by Oja and Karhunen.

    Full Text Available The purpose of this paper is to review, summarize, and illustrate research work involving four audio-based games created within a user-centered design methodology through successive usability tasks and evaluations. These games were designed by considering the mental model of blind children and their styles of interaction to perceive and process data and information. The goal of these games was to enhance the cognitive development of spatial structures, memory, haptic perception, mathematical skills, navigation and orientation, and problem solving of blind children. Findings indicate significant improvements in learning and cognition from using audio-based tools specially tailored for the blind. That is, technologies for blind children, carefully tailored through user-centered design approaches, can make a significant contribution to cognitive development of these children. This paper contributes new insight into the design and implementation of audio-based virtual environments to facilitate learning and cognition in blind children.

    Full Text Available This work was a part of a broader empirical study of Internet users with excessive and dysfunctional Internet use symptoms. The aim of this particular article was to describe user profiles of Internet addicts in Serbia. The study recruited 100 subjects in total, 50 in both the clinical and control group. The clinical group included the Internet users who asked for professional help due to the symptoms of the excessive Internet use and fulfilled the diagnostic criteria for Internet behavior disorder proposed by the American Psychology Association. The results have shown that population with Internet addiction symptoms equally included both males and females, mostly adolescent and younger population, teenagers and university students, persons with higher income and users from economically more developed areas of Serbia. The user profile of this group is characterized by frequent logging on with intervals of several hours online at one time, mainly in the evening or at night, and also intensive negative reactions to any form of Internet access deprivation. By means of factor analysis, three dimensions of pathological use have been established: mixed type with particular need for up-to-date information, social interaction addiction and need for fun-seeking, namely pursuing hobbies online (cyberpornography, online games, music, art and so on.

    Sofinowski, E. J.; Boquist, C. L.

    2009-12-01

    Since 2004 the Earth Observing System Data and Information System (EOSDIS) has conducted an annual comprehensive survey of user satisfaction using the American Customer Satisfaction Index (ACSI). Customer satisfaction ratings for EOSDIS consistently rate better than the overall government ratings. As part of the survey users are asked to submit comments concerning their experiences and interests. These user comments provide valuable insight into the effect of data center processes on users' experiences. Although user satisfaction has remained high, their preferences have changed with the rapid advances in web-based services. This analysis investigates the correlation between user comments, process changes or capability improvements at the individual data centers, and whether the changes at the data centers and web sites show a corresponding increase in user satisfaction. We will evaluate the comments in the areas of Product Search, Product Selection and Order, Delivery, Product Quality and Customer Support.

    Full Text Available The present work aims at analyzing the profiles of social networks’ users, having accomplished an online questionnaire. A sample of 230 cases was obtained (limited to a deadline of a thesis that combined this study with another about enterprises’ involvement in social networks. From the socio-demographic data obtained (age, time of day in social networks, level of education and occupational status there are different behaviors. The results highlight the need of harnessing the potential of recruitment and business partnerships/projects through social networks. This is important because the vast majority of respondents use these platforms for more than one year and a significant percentage accesses them every day. Another issue is that mobile phone connection has a significant expression, thus relevant for ubiquitous business or work applications. Regarding the actions performed, besides seeing/sending messages as the most usually done, searching for knowledge (new contents is also expressive what is relevant for innovative initiatives. Regarding the motivation factors, it is interesting that besides communication with friends and meeting old friends, the use of such platforms for professional relations has high importance what corroborates some potentials mentioned.

  7. The users centered design of a new digital fluorometer

    International Nuclear Information System (INIS)

    The fluorometer is the equipment used in chemical analysis laboratories, research institutes and nuclear fuel cycle companies. This equipment measures an unknown amount of uranium in ores, rivers, etc. The fluorometer functioning is based on the uranium fluorescence when submitted to the ultraviolet radiation incidence. The fluorescence is measured by an electronic optic system with optics filters, photomultiplier tube, and a current amplifier. The user centered design involves the user in the product development in all phases of the design process. Users are not simply consulted at the beginning of the design process and evaluated the system at the end; they are treated as partners throughout the design process. The user centered design emphasizes the needs and abilities of the users and improves the usability of the equipment. The activity centered design emphasizes the development of the equipment with a deep understanding of the users activities and of the current work practices of the users. The aim of this paper is to present a methodological framework that contributes to the design and evaluation of a new digital fluorometer towards an approach related to the users and their activities. This methodological framework includes users-based testing, interviews, questionnaires, human factors standards and guidelines, the users activity analysis and users satisfaction questionnaire.

  8. Modeling and clustering users with evolving profiles in usage streams

    KAUST Repository

    Zhang, Chongsheng

    2012-09-01

    Today, there is an increasing need of data stream mining technology to discover important patterns on the fly. Existing data stream models and algorithms commonly assume that users\\' records or profiles in data streams will not be updated or revised once they arrive. Nevertheless, in various applications such asWeb usage, the records/profiles of the users can evolve along time. This kind of streaming data evolves in two forms, the streaming of tuples or transactions as in the case of traditional data streams, and more importantly, the evolving of user records/profiles inside the streams. Such data streams bring difficulties on modeling and clustering for exploring users\\' behaviors. In this paper, we propose three models to summarize this kind of data streams, which are the batch model, the Evolving Objects (EO) model and the Dynamic Data Stream (DDS) model. Through creating, updating and deleting user profiles, these models summarize the behaviors of each user as a profile object. Based upon these models, clustering algorithms are employed to discover interesting user groups from the profile objects. We have evaluated all the proposed models on a large real-world data set, showing that the DDS model summarizes the data streams with evolving tuples more efficiently and effectively, and provides better basis for clustering users than the other two models. © 2012 IEEE.

  10. Effectively identifying user profiles in network and host metrics

    Science.gov (United States)

    Murphy, John P.; Berk, Vincent H.; Gregorio-de Souza, Ian

    2010-04-01

    This work presents a collection of methods that is used to effectively identify users of computers systems based on their particular usage of the software and the network. Not only are we able to identify individual computer users by their behavioral patterns, we are also able to detect significant deviations in their typical computer usage over time, or compared to a group of their peers. For instance, most people have a small, and relatively unique selection of regularly visited websites, certain email services, daily work hours, and typical preferred applications for mandated tasks. We argue that these habitual patterns are sufficiently specific to identify fully anonymized network users. We demonstrate that with only a modest data collection capability, profiles of individual computer users can be constructed so as to uniquely identify a profiled user from among their peers. As time progresses and habits or circumstances change, the methods presented update each profile so that changes in user behavior can be reliably detected over both abrupt and gradual time frames, without losing the ability to identify the profiled user. The primary benefit of our methodology allows one to efficiently detect deviant behaviors, such as subverted user accounts, or organizational policy violations. Thanks to the relative robustness, these techniques can be used in scenarios with very diverse data collection capabilities, and data privacy requirements. In addition to behavioral change detection, the generated profiles can also be compared against pre-defined examples of known adversarial patterns.

  11. Residential Consumption Scheduling Based on Dynamic User Profiling

    Science.gov (United States)

    Mangiatordi, Federica; Pallotti, Emiliano; Del Vecchio, Paolo; Capodiferro, Licia

    Deployment of household appliances and of electric vehicles raises the electricity demand in the residential areas and the impact of the building's electrical power. The variations of electricity consumption across the day, may affect both the design of the electrical generation facilities and the electricity bill, mainly when a dynamic pricing is applied. This paper focuses on an energy management system able to control the day-ahead electricity demand in a residential area, taking into account both the variability of the energy production costs and the profiling of the users. The user's behavior is dynamically profiled on the basis of the tasks performed during the previous days and of the tasks foreseen for the current day. Depending on the size and on the flexibility in time of the user tasks, home inhabitants are grouped in, one over N, energy profiles, using a k-means algorithm. For a fixed energy generation cost, each energy profile is associated to a different hourly energy cost. The goal is to identify any bad user profile and to make it pay a highest bill. A bad profile example is when a user applies a lot of consumption tasks and low flexibility in task reallocation time. The proposed energy management system automatically schedules the tasks, solving a multi-objective optimization problem based on an MPSO strategy. The goals, when identifying bad users profiles, are to reduce the peak to average ratio in energy demand, and to minimize the energy costs, promoting virtuous behaviors.

    Full Text Available Abstract Background As physical and cognitive rehabilitation protocols utilizing virtual environments transition from single applications to comprehensive rehabilitation programs there is a need for a new design cycle methodology. Current human-computer interaction designs focus on usability without benchmarking technology within a user-in-the-loop design cycle. The field of virtual rehabilitation is unique in that determining the efficacy of this genre of computer-aided therapies requires prior knowledge of technology issues that may confound patient outcome measures. Benchmarking the technology (e.g., displays or data gloves using healthy controls may provide a means of characterizing the "normal" performance range of the virtual rehabilitation system. This standard not only allows therapists to select appropriate technology for use with their patient populations, it also allows them to account for technology limitations when assessing treatment efficacy. Methods An overview of the proposed user-centered design cycle is given. Comparisons of two optical see-through head-worn displays provide an example of benchmarking techniques. Benchmarks were obtained using a novel vision test capable of measuring a user's stereoacuity while wearing different types of head-worn displays. Results from healthy participants who performed both virtual and real-world versions of the stereoacuity test are discussed with respect to virtual rehabilitation design. Results The user-centered design cycle argues for benchmarking to precede virtual environment construction, especially for therapeutic applications. Results from real-world testing illustrate the general limitations in stereoacuity attained when viewing content using a head-worn display. Further, the stereoacuity vision benchmark test highlights differences in user performance when utilizing a similar style of head-worn display. These results support the need for including benchmarks as a means of better

    Sousa, Kênia; Vanderdonckt, Jean

    Business Performer-Centered Design of User Interfaces is a new design methodology that adopts business process (BP) definition and a business performer perspective for managing the life cycle of user interfaces of enterprise systems. In this methodology, when the organization has a business process culture, the business processes of an organization are firstly defined according to a traditional methodology for this kind of artifact. These business processes are then transformed into a series of task models that represent the interactive parts of the business processes that will ultimately lead to interactive systems. When the organization has its enterprise systems, but not yet its business processes modeled, the user interfaces of the systems help derive tasks models, which are then used to derive the business processes. The double linking between a business process and a task model, and between a task model and a user interface model makes it possible to ensure traceability of the artifacts in multiple paths and enables a more active participation of business performers in analyzing the resulting user interfaces. In this paper, we outline how a human-perspective is used tied to a model-driven perspective.

    2014-10-01

    With the increase in resource-sharing websites such as YouTube and Flickr, many shared resources have arisen on the Web. Personalized searches have become more important and challenging since users demand higher retrieval quality. To achieve this goal, personalized searches need to take users' personalized profiles and information needs into consideration. Collaborative tagging (also known as folksonomy) systems allow users to annotate resources with their own tags, which provides a simple but powerful way for organizing, retrieving and sharing different types of social resources. In this article, we examine the limitations of previous tag-based personalized searches. To handle these limitations, we propose a new method to model user profiles and resource profiles in collaborative tagging systems. We use a normalized term frequency to indicate the preference degree of a user on a tag. A novel search method using such profiles of users and resources is proposed to facilitate the desired personalization in resource searches. In our framework, instead of the keyword matching or similarity measurement used in previous works, the relevance measurement between a resource and a user query (termed the query relevance) is treated as a fuzzy satisfaction problem of a user's query requirements. We implement a prototype system called the Folksonomy-based Multimedia Retrieval System (FMRS). Experiments using the FMRS data set and the MovieLens data set show that our proposed method outperforms baseline methods. PMID:24939833

    Full Text Available Abstract Background Personality traits are considered risk factors for drug use, and, in turn, the psychoactive substances impact individuals' traits. Furthermore, there is increasing interest in developing treatment approaches that match an individual's personality profile. To advance our knowledge of the role of individual differences in drug use, the present study compares the personality profile of tobacco, marijuana, cocaine, and heroin users and non-users using the wide spectrum Five-Factor Model (FFM of personality in a diverse community sample. Method Participants (N = 1,102; mean age = 57 were part of the Epidemiologic Catchment Area (ECA program in Baltimore, MD, USA. The sample was drawn from a community with a wide range of socio-economic conditions. Personality traits were assessed with the Revised NEO Personality Inventory (NEO-PI-R, and psychoactive substance use was assessed with systematic interview. Results Compared to never smokers, current cigarette smokers score lower on Conscientiousness and higher on Neuroticism. Similar, but more extreme, is the profile of cocaine/heroin users, which score very high on Neuroticism, especially Vulnerability, and very low on Conscientiousness, particularly Competence, Achievement-Striving, and Deliberation. By contrast, marijuana users score high on Openness to Experience, average on Neuroticism, but low on Agreeableness and Conscientiousness. Conclusion In addition to confirming high levels of negative affect and impulsive traits, this study highlights the links between drug use and low Conscientiousness. These links provide insight into the etiology of drug use and have implications for public health interventions.

  2. Entropy-Based Privacy against Profiling of User Mobility

    2015-06-01

    Full Text Available Location-based services (LBSs flood mobile phones nowadays, but their use poses an evident privacy risk. The locations accompanying the LBS queries can be exploited by the LBS provider to build the user profile of visited locations, which might disclose sensitive data, such as work or home locations. The classic concept of entropy is widely used to evaluate privacy in these scenarios, where the information is represented as a sequence of independent samples of categorized data. However, since the LBS queries might be sent very frequently, location profiles can be improved by adding temporal dependencies, thus becoming mobility profiles, where location samples are not independent anymore and might disclose the user’s mobility patterns. Since the time dimension is factored in, the classic entropy concept falls short of evaluating the real privacy level, which depends also on the time component. Therefore, we propose to extend the entropy-based privacy metric to the use of the entropy rate to evaluate mobility profiles. Then, two perturbative mechanisms are considered to preserve locations and mobility profiles under gradual utility constraints. We further use the proposed privacy metric and compare it to classic ones to evaluate both synthetic and real mobility profiles when the perturbative methods proposed are applied. The results prove the usefulness of the proposed metric for mobility profiles and the need for tailoring the perturbative methods to the features of mobility profiles in order to improve privacy without completely loosing utility.

After analyzing the related works, a general structure of the personalized multimedia information retrieval system is given, which combines online module and offline module. Firstly, we collect a large-sale of photos from multimedia information sharing websites. Then, we record the information of the users who upload the multimedia information. For a given user, we save his history data which could describe the multimedia data. Secondly, the relationship between contents of multimedia data and semantic information is analyzed and then the user interest model is constructed by a modified LDA model which can integrate all the influencing factors in the task of multimedia information retrieval. Thirdly, the query distributions of all the topics can be estimated by the proposed modified LDA model. Thirdly, based on the above offline computing process, the online personalized multimedia information ranking algorithm is given which utilize the user interest model and the query word. Fourthly, multimedia information retrieval results are obtained using the proposed personalized multimedia information ranking algorithm. Finally, performance evaluation is conducted by a series of experiments to test the performance of the proposed algorithm compared with other methods on different datasets.

    Energy profiles are essentially detailed energy balances of refineries showing all inputs and losses for the total refinery and for each of the individual processing units. By showing the losses from each individual heater, exchanger, etc., the items with the greatest potential for saving energy are pinpointed for further evaluation. This User's Guide contains the step-by-step procedure that has been developed for preparing energy profiles at any refinery. The guide is written for people familiar with refinery equipment and operations and should provide sufficient guidance so that problems in preparing an energy profile at any refinery can be resolved. The technique is presented as four parts covering preparation, data gathering, performing calculations, and preparing the profiles. Section 2 on preparation gives the steps to take in starting the project and the procedures to follow in making preparations for gathering the raw data needed to calculate the various energy balances that are used in developing refinery energy profiles. Section 3 gives the procedures for gathering the raw data at a refinery. Section 4 gives the procedures for calculating the various energy balances. Section 5 gives the procedures for preparing the profiles once the various calculations have been completed.

    Directory of Open Access Journals (Sweden)

    Maria Papadogiorgaki

    2008-01-01

    Full Text Available This paper presents a distributed client-server architecture for the personalized delivery of textual news content to mobile users. The user profile consists of two separate models, that is, the long-term interests are stored in a skeleton profile on the server and the short-term interests in a detailed profile in the handset. The user profile enables a high-level filtering of available news content on the server, followed by matching of detailed user preferences in the handset. The highest rated items are recommended to the user, by employing an efficient ranking process. The paper focuses on a two-level learning process, which is employed on the client side in order to automatically update both user profile models. It involves the use of machine learning algorithms applied to the implicit and explicit user feedback. The system's learning performance has been systematically evaluated based on data collected from regular system users.

    Full Text Available Problem statement: Ontological user profile generation was a semantic approach to derive richer concept based user profiles. It depends on the semantic relationship of concepts. This study focuses on ontology to derive concept oriented user profile based on user search queries and clicked documents.This study proposes concept based on topic ontology which derives the concept based user profiles more independently. It was possible to improve the search engine processes more efficiently. Approach: This process consists of individual user’s interests, topical categories of user interests and identifies the relationship among the concepts. The proposed approach was based on topic ontology for concept based user profile generation from search engine logs. Spreading activation algorithm was used to optimize the relevance of search engine results. Topic ontology is constructed to identify the user interest by assigning activation values and explore the topics similarity of user preferences. Results: To update and maintain the interest scores, spreading activation algorithm was proposed. User interest may change over the period of time which was reflected to user profiles. According to profile changes, search engine was personalized by assigning interest scores and weight to the topics. Conclusion: Experiments illustrate the efficacy of proposed approach and with the help of topic ontology user preferences can be identified correctly. It improves the quality of the search engine personalization by identifying the user’s precise needs.

  12. The impact of user centered design on student motivation

    Locker, Craig T.

    There is a current push for STEM education within the U.S.; however current studies show that students' interest to pursue STEM fields is decreasing as they progress through high school. This lose in interest has shown to have a strong tie to students' perceived levels of motivation towards the subject. The question that this studied set out to answer was if user centered design (UCD) would affect students perceived level of motivation. For this study a treatment of UCD was compared to a traditional high school engineering design curriculum, with the goal to identify if UCD would have a positive effect on the students perceived level of motivation. 59 9th grade high school students from an urban Midwestern city were selected to participate. Students were given a pre and posttest to determine their levels of motivation before and after the comparison or treatment. Analysis showed that students perceived level of intrinsic and extrinsic motivation significantly went up in the treatment group. The study concluded that due to the ease of implementation and low cost of deployment that UCD should be introduced into high school design challenges that focus on developing a solution for an external stakeholder.

    Full Text Available Personalization and adaptation to the user profile capability are the hottest issues to ensure ambientassisted living and context awareness in nowadays environments. With the growing healthcare andwellbeing context aware applications, modeling security policies becomes an important issue in thedesign of future access control models. This requires rich semantics using ontology modeling for themanagement of services provided to dependant people. However, current access control models remainunsuitable due to lack of personalization, adaptability and smartness to the handicap situation.In this paper, we propose a novel adaptable access control model and its related architecture in whichthe security policy is based on the handicap situation analyzed from the monitoring of user’s behavior inorder to grant a service using any assistive device within intelligent environment. The design of ourmodel is an ontology-learning and evolving security policy for predicting the future actions of dependentpeople. This is reached by reasoning about historical data, contextual data and user behavior accordingto the access rules that are used in the inference engine to provide the right service according to theuser’s needs.

    2012-01-01

    Full Text Available Introduction: The cochlear implant is a device that is intended to substitute for the function of cochlear hair cells, electrically stimulate auditory nerve fibers, and contribute to the perception of speech sounds. However, the surgical procedure alone is not enough for the user to achieve favorable results in habilitation/rehabilitation. Objective: To characterize the patients from Manaus who have received cochlear implants based on the criteria for surgery. Methods: We conducted a retrospective cross-sectional study of 15 cases and recorded etiological aspects of deafness, age, gender, duration of implant use, use of hearing aids, and participation in individual therapy. Data were recorded in a protocol designed specifically for this purpose. All patients were natives of Manaus. Results: The leading etiological aspect was ototoxicity associated with prematurity in newborns undergoing treatment in the neonatal intensive care unit. The age at surgery is carefully observed in the evaluation of implant centers, as well as if the candidate is pre-or post-lingual. In this study, 73% of patients were pre-lingual and did not benefit from hearing aids. As to the degree and type of hearing loss, 93% had audiological reports indicating profound bilateral sensorineural hearing loss and 7% had severe bilateral sensorineural hearing loss. This latter finding confirmed one of the basic principles of implant placement. Conclusion: This study allowed us to verify that there are reduced number of cochlear implant recipients in Manaus, but they have met the criteria required by implant centers located in other states of Brazil.

    2015-12-01

    With the rapid development of earth observation technology and the rapid increase of remote sensors, the amount of remote sensing data rapidly expands, which leads to increasingly outstanding contradiction of "more and less" remote sensing data. According to the user's preference characteristics, intelligent distribution of remote sensing data is an effective solution to the problem. The user profile model is the basis of intelligent distribution of remote sensing data. This paper intends to (1) establish the user profile model which describes the user's preference characteristics of remote sensing data; (2) develop similarity measure methods of user profile models, according to which similarities of user preference characteristics can be calculated; (3) put forward prediction methods of the user's ratings of remote sensing data, based on which remote sensing data can be collaboratively distributed.

    2007-12-01

    Full Text Available Privacy of web users' query search logs has, since last year's AOL dataset release, been treated as one of the central issues concerning privacy on the Internet, Therefore, the question of privacy preservation has also raised a lot of attention in different communities surrounding the search engines. Usage of clustering methods for providing low level contextual search, wriile retaining high privacy/utility is examined in this paper. By using only the user's cluster membership the search query terms could be no longer retained thus providing less privacy concerns both for the users and companies. The paper brings lightweight framework for combining query words, user similarities and clustering in order to provide a meaningful way of mining user searches while protecting their privacy. This differs from previous attempts for privacy preserving in the attempt to anonymize the queries instead of the users.

    The Gemini Science User Support Department (SUSD) was formed a little more than a year ago to create a collaborative community of users and staff and to consolidate existing post-observing support throughout the observatory for more efficient use of resources as well as better visibility amongst our user community. This poster is an opportunity to exchange ideas about how Gemini can improve your experience while working with the Observatory and present details about new avenues of post-observing support coming soon. We encourage your feedback at any time.Shortly after its creation, the SUSD conducted a complete revision of the communication cycle between Gemini and its community of researchers. The cycle was then revisited from the perspective of an astronomer interested in using Gemini for their research. This exercise led to a series of proposed changes that are currently under development, and the implementation of a sub-selection is expected in 2016, including the following. (1) Email notifications: Gemini users will receive new forms of email communications that are more instructive and tailored to their program. The objective is to direct the users more efficiently toward the useful links and documentation all along the lifecycle of the program, from phaseII to after the data are completely reduced. (2) HelpDesk system: The HelpDesk will become more user-friendly and transparent. (3) Webpages: The organization of the Gemini webpages will be redesigned to optimize navigation; especially for anything regarding more critical periods likes phaseIs and phaseIIs. (4) Data Reduction User Forum: Following recommendations from Gemini users, new capabilities were added to the forum, like email notifications, and a voting system, in order to make it more practical. This forum's objective is to bring the Gemini community together to exchange their ideas, thoughts, questions and solutions about data reduction, a sort of Reddit, StackOverflow or Slashdot for Gemini data.

    2015-01-01

    Full Text Available Web with tremendous volume of information retrieves result for user related queries. With the rapid growth of web page recommendation, results retrieved based on data mining techniques did not offer higher performance filtering rate because relationships between user profile and queries were not analyzed in an extensive manner. At the same time, existing user profile based prediction in web data mining is not exhaustive in producing personalized result rate. To improve the query result rate on dynamics of user behavior over time, Hamilton Filtered Regime Switching User Query Probability (HFRS-UQP framework is proposed. HFRS-UQP framework is split into two processes, where filtering and switching are carried out. The data mining based filtering in our research work uses the Hamilton Filtering framework to filter user result based on personalized information on automatic updated profiles through search engine. Maximized result is fetched, that is, filtered out with respect to user behavior profiles. The switching performs accurate filtering updated profiles using regime switching. The updating in profile change (i.e., switches regime in HFRS-UQP framework identifies the second- and higher-order association of query result on the updated profiles. Experiment is conducted on factors such as personalized information search retrieval rate, filtering efficiency, and precision ratio.

    Web with tremendous volume of information retrieves result for user related queries. With the rapid growth of web page recommendation, results retrieved based on data mining techniques did not offer higher performance filtering rate because relationships between user profile and queries were not analyzed in an extensive manner. At the same time, existing user profile based prediction in web data mining is not exhaustive in producing personalized result rate. To improve the query result rate on dynamics of user behavior over time, Hamilton Filtered Regime Switching User Query Probability (HFRS-UQP) framework is proposed. HFRS-UQP framework is split into two processes, where filtering and switching are carried out. The data mining based filtering in our research work uses the Hamilton Filtering framework to filter user result based on personalized information on automatic updated profiles through search engine. Maximized result is fetched, that is, filtered out with respect to user behavior profiles. The switching performs accurate filtering updated profiles using regime switching. The updating in profile change (i.e., switches) regime in HFRS-UQP framework identifies the second- and higher-order association of query result on the updated profiles. Experiment is conducted on factors such as personalized information search retrieval rate, filtering efficiency, and precision ratio. PMID:26221626

    Full Text Available The Web is being a pool of knowledge, where any user visits hundreds of pages for various purposes but keeping track of its relevance for him is a tedious job. An average browser just provides you by the details of your browsing history but has no way to determine what importance the page holds for the user. In this paper we propose a method which aims to generate user profiles automatically depending on the various web pages a user browses over a period of time and the user’s interaction with them. This automatically generated user profile assigns weights to web pages proportional to the user interactions on the webpage and thus indicates relevancy of web pages to the user based on these weights.

    Full Text Available Data warehousing is an essential element of decision support systems. It aims at enabling the userknowledge to make better and faster daily business decisions. To improve this decision support system andto give more and more relevant information to the user, the need to integrate user's profiles into the datawarehouse process becomes crucial. In this paper, we propose to exploit users' preferences as a basis foradapting OLAP (On-Line Analytical Processing queries to the user. For this, we present a user profiledrivendata warehouse approach that allows dening user's profile composed by his/her identifier and a setof his/her preferences. Our approach is based on a general data warehouse architecture and an adaptiveOLAP analysis system. Our main idea consists in creating a data warehouse materialized view for eachuser with respect to his/her profile. This task is performed off-line when the user defines his/her profile forthe first time. Then, when a user query is submitted to the data warehouse, the system deals with his/herdata warehouse materialized view instead of the whole data warehouse. In other words, the datawarehouse view summaries the data warehouse content for the user by taking into account his/herpreferences. Moreover, we are implementing our data warehouse personalization approach under the SQLServer 2005 DBMS (DataBase Management System.

    Personalization and context-aware applications have attracted increasing amounts of attention over recent years due to the emergence of pervasive computing applications. Nevertheless, it still remains a challenge to meet the needs of users while they are on the move. This paper introduces a novel approach for providing personalized, context-aware assistance services for users in mobile environments. Central to the approach is the use of ontological user profile modeling which captures various characteristics of a user in order to create a unique set of profile information. In addition, user profiles can adapt to changing user behavior, thus enabling services to respond to evolving user needs and preferences. We describe the overall system architecture of the proposed approach with special emphasis being placed on the user profile modelling and its expected utility based on a typical use case scenario, i.e., using a smart-phone to address the problem of the outdoor mobility of a person with Dementia. A prototype based on the Android OS is used to illustrate the application. The use of everyday technology for a real world problem highlights the potential and utility of our approach. PMID:23367391

    Unauthorized use of natural resources is a key threat to many protected areas. Approaches to reducing this threat include law enforcement and integrated conservation and development (ICD) projects, but for such ICDs to be targeted effectively, it is important to understand who is illegally using which natural resources and why. The nature of unauthorized behavior makes it difficult to ascertain this information through direct questioning. Bwindi Impenetrable National Park, Uganda, has many ICD projects, including authorizing some local people to use certain nontimber forest resources from the park. However, despite over 25 years of ICD, unauthorized resource use continues. We used household surveys, indirect questioning (unmatched count technique), and focus group discussions to generate profiles of authorized and unauthorized resource users and to explore motivations for unauthorized activity. Overall, unauthorized resource use was most common among people from poor households who lived closest to the park boundary and farthest from roads and trading centers. Other motivations for unauthorized resource use included crop raiding by wild animals, inequity of revenue sharing, and lack of employment, factors that created resentment among the poorest communities. In some communities, benefits obtained from ICD were reported to be the greatest deterrents against unauthorized activity, although law enforcement ranked highest overall. Despite the sensitive nature of exploring unauthorized resource use, management-relevant insights into the profiles and motivations of unauthorized resource users can be gained from a combination of survey techniques, as adopted here. To reduce unauthorized activity at Bwindi, we suggest ICD benefit the poorest people living in remote areas and near the park boundary by providing affordable alternative sources of forest products and addressing crop raiding. To prevent resentment from driving further unauthorized activity, ICDs should be

    1990-01-01

    A comprehensive description of the structural and instrumentation hardware and the experimental capabilities of the 105-meter Marshall Space Flight Center Drop Tube Facility is given. This document is to serve as a guide to the investigator who wishes to perform materials processing experiments in the Drop Tube. Particular attention is given to the Tube's hardware to which an investigator must interface to perform experiments. This hardware consists of the permanent structural hardware (with such items as vacuum flanges), and the experimental hardware (with the furnaces and the sample insertion devices). Two furnaces, an electron-beam and an electromagnetic levitator, are currently used to melt metallic samples in a process environment that can range from 10(exp -6) Torr to 1 atmosphere. Details of these furnaces, the processing environment gases/vacuum, the electrical power, and data acquisition capabilities are specified to allow an investigator to design his/her experiment to maximize successful results and to reduce experimental setup time on the Tube. Various devices used to catch samples while inflicting minimum damage and to enhance turnaround time between experiments are described. Enough information is provided to allow an investigator who wishes to build his/her own furnace or sample catch devices to easily interface it to the Tube. The experimental instrumentation and data acquisition systems used to perform pre-drop and in-flight measurements of the melting and solidification process are also detailed. Typical experimental results are presented as an indicator of the type of data that is provided by the Drop Tube Facility. A summary bibliography of past Drop Tube experiments is provided, and an appendix explaining the noncontact temperature determination of free-falling drops is provided. This document is to be revised occasionally as improvements to the Facility are made and as the summary bibliography grows.

    Full Text Available To overcome limits of traditional passive remote sensing data distribution methods, personalization is an inevitable trend of spatial information service. User profile is the basic foundation for personalized, active and accurate spatial information dissemination service, which can be used in the definition of users' preferences or interests of remote sensing data. In view of the coverage characteristics of remote sensing data in spatial and spectrum, this paper adopted the interval mathematics method into the representation of user profiles. Based on user profiles, the concepts of the correlation degree and interest degree are introduced. In addition, by the construction of decision matrixes, the solutions of the generations of intelligent services can be converted into the solutions of multiple attribute decision problems. Finally, an instance is given to show the usability of the presented method.

    In this paper, we present a novel approach to perform similarity queries over medical images, maintaining the semantics of a given query posted by the user. Content-based image retrieval systems relying on relevance feedback techniques usually request the users to label relevant/irrelevant images. Thus, we present a highly effective strategy to survey user profiles, taking advantage of such labeling to implicitly gather the user perceptual similarity. The profiles maintain the settings desired for each user, allowing tuning of the similarity assessment, which encompasses the dynamic change of the distance function employed through an interactive process. Experiments on medical images show that the method is effective and can improve the decision making process during analysis. PMID:24480158

  14. A Context-Aware Mobile User Behavior-Based Neighbor Finding Approach for Preference Profile Construction

    Directory of Open Access Journals (Sweden)

    Qian Gao

    2016-01-01

    Full Text Available In this paper, a new approach is adopted to update the user preference profile by seeking users with similar interests based on the context obtainable for a mobile network instead of from desktop networks. The trust degree between mobile users is calculated by analyzing their behavior based on the context, and then the approximate neighbors are chosen by combining the similarity of the mobile user preference and the trust degree. The approach first considers the communication behaviors between mobile users, the mobile network services they use as well as the corresponding context information. Then a similarity degree of the preference between users is calculated with the evaluation score of a certain mobile web service provided by a mobile user. Finally, based on the time attenuation function, the users with similar preference are found, through which we can dynamically update the target user’s preference profile. Experiments are then conducted to test the effect of the context on the credibility among mobile users, the effect of time decay factors and trust degree thresholds. Simulation shows that the proposed approach outperforms two other methods in terms of Recall Ratio, Precision Ratio and Mean Absolute Error, because neither of them consider the context mobile information.

    Full Text Available Privacy-preserving profile matching, a challenging task in mobile social networks, is getting more attention in recent years. In this paper, we propose a novel scheme that is based on ciphertext-policy attribute-based encryption to tackle this problem. In our scheme, a user can submit a preference-profile and search for users with matching-profile in decentralized mobile social networks. In this process, no participant's profile and the submitted preference-profile is exposed. Meanwhile, a secure communication channel can be established between the pair of successfully matched users. In contrast to existing related schemes which are mainly based on the secure multi-party computation, our scheme can provide verifiability (both the initiator and any unmatched user cannot cheat each other to pretend to be matched, and requires few interactions among users. We provide thorough security analysis and performance evaluation on our scheme, and show its advantages in terms of security, efficiency and usability over state-of-the-art schemes.

    2004-01-01

    As companies increase the quantity of information they provide through their Web sites, it is critical that content is structured with an appropriate architecture. However, resource constraints often limit the ability of companies to apply all Web design principles completely. This study quantifies the effects of two major information architecture principles in a controlled study that isolates the incremental effects of organizational scheme and labeling on user performance and satisfaction. Sixty participants with a wide range of Internet and on-line shopping experience were recruited to complete a series of shopping tasks on a prototype retail shopping Web site. User-centered labels provided a significant benefit in performance and satisfaction over labels obtained through company-centered methods. User-centered organization did not result in improved performance except when the label quality was poor. Significant interactions suggest specific guidelines for allocating resources in Web site design. Applications of this research include the design of Web sites for any commercial application, particularly E-commerce. PMID:15151158

    Full Text Available In mobile communications networks, Location Management enables the roaming of the user in the coverage area. The employment of the call and mobility patterns of the user can help minimize the signaling costs involved in Location Management, and optimize the available radio resources. In this paper, we carry out an exhaustive analysis of the location update costs involved in a user profile-based Location Management algorithm, and compare its performance with the classical strategy of static location areas. As original contributions, we introduce two new algorithms to obtain the β parameters, useful for the calculation of the Location Management signaling costs. Making use of these new algorithms, we show the convenience of the application of user profile-based strategies for Location Management in order to optimize the available radio resources, and we obtain practical guidelines for the optimum design of mobile communications networks.

    Full Text Available This study implemented a systematic user-centered training protocol for a 4-class brain-computer interface (BCI. The goal was to optimize the BCI individually in order to achieve high performance within few sessions for all users. Eight able-bodied volunteers, who were initially naïve to the use of a BCI, participated in 10 sessions over a period of about 5 weeks. In an initial screening session, users were asked to perform the following seven mental tasks while multi-channel EEG was recorded: mental rotation, word association, auditory imagery, mental subtraction, spatial navigation, motor imagery of the left hand and motor imagery of both feet. Out of these seven mental tasks, the best 4-class combination as well as most reactive frequency band (between 8-30 Hz was selected individually for online control. Classification was based on common spatial patterns and Fisher's linear discriminant analysis. The number and time of classifier updates varied individually. Selection speed was increased by reducing trial length. To minimize differences in brain activity between sessions with and without feedback, sham feedback was provided in the screening and calibration runs in which usually no real-time feedback is shown. Selected task combinations and frequency ranges differed between users. The tasks that were included in the 4-class combination most often were (1 motor imagery of the left hand (2, one brain-teaser task (word association or mental subtraction (3, mental rotation task and (4 one more dynamic imagery task (auditory imagery, spatial navigation, imagery of the feet. Participants achieved mean performances over sessions of 44-84% and peak performances in single-sessions of 58-93% in this user-centered 4-class BCI protocol. This protocol is highly adjustable to individual users and thus could increase the percentage of users who can gain and maintain BCI control. A high priority for future work is to examine this protocol with severely

    Social Networking Sites (SNSs) have showed an exponential growth in the last years. The first step for an efficient use of SNSs stems from an understanding of the individuals' behaviors within these sites. In this research, we have obtained a typology of SNS users through a latent segmentation approach, based on the frequency by which users perform different activities within the SNSs, sociodemographic variables, experience in SNSs, and dimensions related to their interaction patterns. Four different segments have been obtained. The "introvert" and "novel" users are the more occasional. They utilize SNSs mainly to communicate with friends, although "introverts" are more passive users. The "versatile" user performs different activities, although occasionally. Finally, the "expert-communicator" performs a greater variety of activities with a higher frequency. They tend to perform some marketing-related activities such as commenting on ads or gathering information about products and brands as well as commenting ads. The companies can take advantage of these segmentation schemes in different ways: first, by tracking and monitoring information interchange between users regarding their products and brands. Second, they should match the SNS users' profiles with their market targets to use SNSs as marketing tools. Finally, for most business, the expert users could be interesting opinion leaders and potential brand influencers. PMID:21288133

    Full Text Available In this paper, we address the topic of user-centered design (UCD for cartography, GIScience, and visual analytics. Interactive maps are ubiquitous in modern society, yet they often fail to “work” as they could or should. UCD describes the process of ensuring interface success—map-based or otherwise—by gathering input and feedback from target users throughout the design and development of the interface. We contribute to the expanding literature on UCD for interactive maps in two ways. First, we synthesize core concepts on UCD from cartography and related fields, as well as offer new ideas, in order to organize existing frameworks and recommendations regarding the UCD of interactive maps. Second, we report on a case study UCD process for GeoVISTA CrimeViz, an interactive and web-based mapping application supporting visual analytics of criminal activity in space and time. The GeoVISTA CrimeViz concept and interface were improved iteratively by working through a series of user→utility→usability loops in which target users provided input and feedback on needs and designs (user, prompting revisions to the conceptualization and functional requirements of the interface (utility, and ultimately leading to new mockups and prototypes of the interface (usability for additional evaluation by target users (user… and so on. Together, the background review and case study offer guidance for applying UCD to interactive mapping projects, and demonstrate the benefit of including target users throughout design and development.

  17. User-centered virtual environment assessment and design for cognitive rehabilitation applications

    Science.gov (United States)

    Fidopiastis, Cali Michael

    Virtual environment (VE) design for cognitive rehabilitation necessitates a new methodology to ensure the validity of the resulting rehabilitation assessment. We propose that benchmarking the VE system technology utilizing a user-centered approach should precede the VE construction. Further, user performance baselines should be measured throughout testing as a control for adaptive effects that may confound the metrics chosen to evaluate the rehabilitation treatment. To support these claims we present data obtained from two modules of a user-centered head-mounted display (HMD) assessment battery, specifically resolution visual acuity and stereoacuity. Resolution visual acuity and stereoacuity assessments provide information about the image quality achieved by an HMD based upon its unique system parameters. When applying a user-centered approach, we were able to quantify limitations in the VE system components (e.g., low microdisplay resolution) and separately point to user characteristics (e.g., changes in dark focus) that may introduce error in the evaluation of VE based rehabilitation protocols. Based on these results, we provide guidelines for calibrating and benchmarking HMDs. In addition, we discuss potential extensions of the assessment to address higher level usability issues. We intend to test the proposed framework within the Human Experience Modeler (HEM), a testbed created at the University of Central Florida to evaluate technologies that may enhance cognitive rehabilitation effectiveness. Preliminary results of a feasibility pilot study conducted with a memory impaired participant showed that the HEM provides the control and repeatability needed to conduct such technology comparisons. Further, the HEM affords the opportunity to integrate new brain imaging technologies (i.e., functional Near Infrared Imaging) to evaluate brain plasticity associated with VE based cognitive rehabilitation.

    The High Temperature Materials Laboratory (HTML) User Program at ORNL was established to help solve high-temperature materials problems that limit the efficiency and reliability of advanced energy-conversion systems. Both proprietary and nonproprietary research can be conducted within the user program. The facilities are open to researchers in US industry, universities, and federal laboratories. The Residual Stress User Center (RSUC), one of the six HTML user centers, was recently established and consists of two high precision x-ray diffraction systems for measurement of residual strain and texture. Both biaxial and triaxial residual strain data can be collected. Attachments to the diffraction system include a position sensitive detector and a laser specimen positioning system. The RSUC has capabilities for electropolishing and strain measurement with strain gauges. A complementary neutron diffraction facility has recently been developed and demonstrated at the High Flux Isotope Reactor at ORNL. The neutron diffraction facility enables mapping of macro residual stresses throughout the volume of a component, complementing the near surface stress measurements available by x-ray diffraction. The neutron facility has been proposed as an addition to the RSUC.

    Specific personality traits have been linked with substance use disorders (SUDs), genetic mechanisms, and brain systems. Thus, determining the specificity of personality traits to types of SUD can advance the field towards defining SUD endophenotypes as well as understanding the brain systems involved for the development of novel treatments. Disentangling these factors is particularly important in highly co morbid SUDs, such as marijuana and nicotine use, so treatment can occur effectively for both. This study evaluated personality traits that distinguish isolated and co-morbid use of marijuana and nicotine. To that end, we collected the NEO Five Factor Inventory in participants who used marijuana-only (n=59), nicotine-only (n=27), both marijuana and nicotine (n=28), and in non-using controls (n=28). We used factor analyses to identify personality profiles, which are linear combinations of the five NEO Factors. We then conducted Receiver Operating Characteristics (ROC) curve analysis to test accuracy of the personality factors in discriminating isolated and co-morbid marijuana and nicotine users from each other. ROC curve analysis distinguished the four groups based on their NEO personality patterns. Results showed that NEO Factor 2 (openness, extraversion, agreeableness) discriminated marijuana and marijuana+nicotine users from controls and nicotine-only users with high predictability. Additional ANOVA results showed that the openness dimension discriminated marijuana users from nicotine users. These findings suggest that personality dimensions distinguish marijuana users from nicotine users and should be considered in prevention strategies. PMID:27086256

    The Upper Stage (US) section of the National Aeronautics and Space Administration's (NASA) Ares I rocket will require internal access platforms for maintenance tasks performed by humans inside the vehicle. Tasks will occur during expensive critical path operations at Kennedy Space Center (KSC) including vehicle stacking and launch preparation activities. Platforms must be translated through a small human access hatch, installed in an enclosed worksite environment, support the weight of ground operators and be removed before flight - and their design must minimize additional vehicle mass at attachment points. This paper describes the application of a user-centered conceptual design process and the unique challenges encountered within NASA's systems engineering culture focused on requirements and "heritage hardware". The NASA design team at Marshall Space Flight Center (MSFC) initiated the user-centered design process by studying heritage internal access kits and proposing new design concepts during brainstorming sessions. Simultaneously, they partnered with the Technology Transfer/Innovative Partnerships Program to research inflatable structures and dynamic scaffolding solutions that could enable ground operator access. While this creative, technology-oriented exploration was encouraged by upper management, some design stakeholders consistently opposed ideas utilizing novel, untested equipment. Subsequent collaboration with an engineering consulting firm improved the technical credibility of several options, however, there was continued resistance from team members focused on meeting system requirements with pre-certified hardware. After a six-month idea-generating phase, an intensive six-week effort produced viable design concepts that justified additional vehicle mass while optimizing the human factors of platform installation and use. Although these selected final concepts closely resemble heritage internal access platforms, challenges from the application of the

    The software interface - whether graphical, command-oriented, menu-driven, or in the form of subroutine calls - shapes the user`s perception of what software can do. It also establishes upper bounds on software usability. Numerical software interfaces typically are based on the designer`s understanding of how the software should be used. That is a poor foundation for usability, since the features that are ``instinctively right`` from the developer`s perspective are often the very ones that technical programmers find most objectionable or most difficult to learn. This paper discusses how numerical software interfaces can be improved by involving users more actively in design, a process known as user-centered design (UCD). While UCD requires extra organization and effort, it results in much higher levels of usability and can actually reduce software costs. This is true not just for graphical user interfaces, but for all software interfaces. Examples show how UCD improved the usability of a subroutine library, a command language, and an invocation interface.

    As healthcare consumers increasingly turn to the World Wide Web (WWW) to obtain health information, it is imperative that health-related websites are user-centered. Websites are often developed without consideration of intended users' characteristics, literacy levels, preferences, and information goals resulting in user dissatisfaction, abandonment of the website, and ultimately the need for costly redesign. This paper provides a methodological review of a user-centered framework that incorporates best practices in literacy, information quality, and human-computer interface design and evaluation to guide the design and redesign process of a consumer health website. Following the description of the methods, a case analysis is presented, demonstrating the successful application of the model in the redesign of a consumer health information website with call center. Comparisons between the iterative revisions of the website showed improvements in usability, readability, and user satisfaction. PMID:21396486

    Full Text Available Being familiar with all the benefits of e-Health and the strategic plan for the Slovenian health sector’s informatization, Telekom Slovenia and the Faculty of Medicine from the University of Maribor, along with other partners, have initiated an e-Health project. The project group is developing various e-Health services that are based on modern ICT (information and communications technology solutions and will be available on several screens. In order to meet the users’ needs and expectations and, consequently, achieve the high acceptance of e-Health services, the user-centered design (UCD approach was employed in the e-Health project. However, during the research it was found that conventional UCD methods are not completely appropriate for older adults: the target population of the e-Health services. That is why the selected UCD methods were modified and adapted for older adults. The modified UCD methods used in the research study are presented in this paper. Using the results of the adapted UCD methods, a prototype for a service named MedReminder was developed. The prototype was evaluated by a group of 12 study participants. The study participants evaluated the MedReminder service as acceptable with a good potential for a high adoption rate among its target population, i.e., older adults.

    Full Text Available Successful aging, independence and capacity for aging in place involves the maintenance and preservation of individuals’ physical, mental and social well-being. Elderly people need to maintain the capacity to perform both activities of daily living (ADL and instrumental activities of daily living (IADL. Advances in Smart Home technologies are increasingly able to provide embedded assessments of an individual’s functional ability in his/her home on a moment-to-moment, daily, and longitudinal basis. To date, in-situ functional assessment systems and research have focused to a greater extent on the advancement of technologies rather than the multi-faceted needs and experiences of users, however the success of any technology depends more on the users than the technology itself. This paper presents strategies for user-centric approaches to identify the technical and design challenges of developing, deploying, and using functional assessment systems in homes occupied by senior citizens. Case studies involved 4 healthy older adults (aged 65+, and examined the home deployment of smart home systems and interfaces aimed at assessment of a combination of ADL and IADL activities. Pre- and post-activity interviews were used to better understand issues related to desire, privacy, technological acceptance, suitability, and need fulfillment/support. The results inform strategies for user-centered functional assessment and assistive technology design and implementation, providing information capture, analysis, and delivery of in-home functional assessment that has the potential to support aging in place.

    2013-01-01

    This paper examines the outcomes for clinicians from their involvement in the development of an electronic clinical hand-over tool developed using principles of user-centered design. Conventional e-health post-implementation evaluations tend to emphasize technology-related (mostly positive) outcomes. More recently, unintended (mostly negative) consequences arising from the implementation of e-health technologies have also been reported. There remains limited focus on the post-implementation outcomes for users, particularly those directly involved in e-health design processes. This paper presents detailed analysis and insights into the outcomes experienced post-implementation by a cohort of junior clinicians involved in developing an electronic clinical handover tool in Tasmania, Australia. The qualitative methods used included observations, semi-structured interviews and analysis of clinical handover notes. Significantly, a number of unanticipated flow-on effects were identified that mitigated some of the challenges arising during the design and implementation of the tool. The paper concludes by highlighting the importance of identifying post-implementation user outcomes beyond conventional system adoption and use and also points to the need for more comprehensive evaluative frameworks to encapsulate these broader socio-technical user outcomes.

The Smart Bedside Station (SBS) is a screen that is installed on the bedside for the personal use and provides a variety of convenient services for the patients. Recently, bedside terminal systems have been increasingly adopted in hospitals due to the rapid growth of advanced technology in healthcare at the point of care. We designed user experience (UX) research to derive users' unmet needs and major functions that are frequently used in the field. To develop the SBS service, a service design methodology, the Double Diamond Design Process Model, was undertaken. The problems or directions of the complex clinical workflow of the hospital, the requirements of stakeholders, and environmental factors were identified through the study. The SBS system services provided to patients were linked to the hospital's main services or to related electronic medical record (EMR) data. Seven key services were derived from the results of the study. The primary services were as follows: Bedside Check In and Out, Bedside Room Service, Bedside Scheduler, Ready for Rounds, My Medical Chart, Featured Healthcare Content, and Bedside Community. This research developed a patient-centered SBS system with improved UX using service design methodology applied to complex and technical medical services, providing insights to improve the current healthcare system.

    This is an observational cross-sectional survey which included 707 individuals from a south Brazilian city (Joaçaba, in Santa Catarina State) aiming to know the alcohol user prevalence as well as the profile of the user. The results showed that 45.5% (322) of that population consume alcohol on regular basis and had used it at least once in the last month. The regular alcohol consumption occurs predominantly on males (p education (p currency (p <0.001). The regular alcohol consumption was greater on those who classified his health status as regular, good or very good (p <0.006), also this relation happen to those people who haven't been under hospital internment in the last year (p <0.013). The depression levels scored by the Beck Depression Inventory (BDI) showed low levels to those who regularly consume alcohol (p <0.047). PMID:20464180

    Full Text Available The goal of this study was to examine what experiences members have with fitness centers that influence their intentions for recommendation. After item generation and content validity, as well as a pilot test, a survey was conducted among members of five different clubs (n=1750. The questionnaire included measures of service quality attributes, accessibility, well-being in life, well-being in a club, and intentions to recommend a fitness center. Results using a structural equation model provide evidence that only service quality attributes and well-being in a club have positive effect on intentions of users to recommend it. Well-being in life has a negative effect on the intentions for recommendation, while accessibility shows no predictive effect. These findings suggest implications for the management of a club, such as the need to create a pleasant environment and to provide a personalized service directed towards the members' goals in order to improve well-being in a club and contribute to increase the intentions to recommend the fitness centers to others.

    Hussain, Zahid; Slany, Wolfgang; Holzinger, Andreas

    This paper investigates how the integration of agile methods and User-Centered Design (UCD) is carried out in practice. For this study, we have applied grounded theory as a suitable qualitative approach to determine what is happening in actual practice. The data was collected by semi-structured interviews with professionals who have already worked with an integrated agile UCD methodology. Further data was collected by observing these professionals in their working context, and by studying their documents, where possible. The emerging themes that the study found show that there is an increasing realization of the importance of usability in software development among agile team members. The requirements are emerging; and both low and high fidelity prototypes based usability tests are highly used in agile teams. There is an appreciation of each other's work from both UCD professionals and developers and both sides can learn from each other.

    What models can effectively guide the creation of eHealth and mHealth technologies? This paper describes the use of the NIATx model as a framework for the user-centered design of a new technology for older adults. The NIATx model is a simple framework of process improvement based on the following principles derived from an analysis of decades of research from various industries about why some projects fail and others succeed: (1) Understand and involve the customer; (2) fix key problems; (3) pick an influential change leader; (4) get ideas from outside the field; (5) use rapid-cycle testing. This paper describes the use of these principles in technology development, the strengths and challenges of using this approach in this context, and lessons learned from the process. Overall, the NIATx model enabled us to produce a user-focused technology that the anecdotal evidence available so far suggests is engaging and useful to older adults. The first and fourth principles were especially important in developing the technology; the fourth proved the most challenging to use. PMID:27025985

    Full Text Available Methcathinone (ephedrone is relatively easily accessible for abuse. Its users develop an extrapyramidal syndrome and it is not known if this is caused by methcathinone itself, by side-ingredients (manganese, or both. In the present study we aimed to clarify molecular mechanisms underlying this condition. We analyzed whole genome gene expression patterns of peripheral blood from 20 methcathinone users and 20 matched controls. Gene expression profile data was analyzed by Bayesian modelling and functional annotation. In order to verify the genechip results we performed quantitative real-time (RT PCR in selected genes. 326 out of analyzed 28,869 genes showed statistically significant differential expression with FDR adjusted p-values below 0.05. Quantitative RT-PCR confirmed differential expression for the most of selected genes. Functional annotation and network analysis indicated that most of the genes were related to activation immunological disease, cellular movement and cardiovascular disease gene network (enrichment score 42. As HIV and HCV infections were confounding factors, we performed additional stratification of patients. A similar functional activation of the immunological disease pathway was evident when we compared patients according to the injection status (past versus current users, balanced for HIV and HCV infection. However, this difference was not large therefore the major effect was related to the HIV status of the patients. Mn-methcathinone abusers have blood transcriptional patterns mostly caused by their HIV and HCV infections.

    Abandoning the assumption that light traces mass, I seek the location of the center of the Local Group of galaxies based solely on kinematic data and the plausible assumption of infall. The available set of positions and radial velocities is shown to be a misleading indicator of Local Group motions, giving a direction to the center offset from the true one; statistical techniques of moderate sophistication do not catch the offset. Corrected calculations show the center to lie in the direction to M31 within the uncertainty of the method, a few degrees. The distance to the center is not well determined, lying about 0.5 Mpc from the Milky Way. The pattern of observed (galactocentric) radial velocities excludes both dynamically important `orphan haloes' and any extended dark matter halo for the Group as a whole, and shows the Group to have formed from a much more extended volume than it presently occupies. Kinematics alone indicates that the mass of the Group is concentrated effectively in M31 and the Milky Way.

Because of this, them invest time to look for devices to streamline results to get a perfect body, between mechanisms used there is the use of anabolic steroids (AS. With the rapid response this kind of treatment, there are aware concerns their side effects such as gynecomastia which is characterized by breast enlargement of man. In an attempt to prevent this effect aesthetically uncomfortable, the users seek take medicines such as tamoxifen to reverse or prevent this situation without proper prescription or monitoring of a pharmacist professional, as well as almost all treatments with EA which are made clandestinely. This work aimed to describe profile among consumers seeking the tamoxifen therapy to prevent or treat gynecomastia induced using EA. The target audience was composed of bodybuilders men that were making anabolic cycles, aiming fast muscular hypertrophy. Two questionnaires were applied, one to the drugstores that sell these drugs and one for bodybuilders who buy these drugs. Tamoxifen user profile found in this study shows that they are young people aged 18 to 35 years old, seeking muscle hypertrophy strength. As the natural results are slow, influenced by training friends, start using EA, even declaring know about the risks to health. Use along with these steroids, tamoxifen, in an attempt to prevent or treat gynecomastia, get the medication in drugstores without a prescription and without the pharmacist questioning, demonstrating that pharmaceutical care is still not fully deployed and functioning

    This document reports survey data collected from the U.S. Department of Energy, Richland Operations Office (DOE-RL), Project Hanford Management Contract (PHMC) companies, and the PHMC enterprise companies for purposes of characterizing the Hanford Local Area Network (HLAN) user profile. Telephone, radio, and pager data are also provided. The data reveal that job tasks of the 8,500 Hanford Site workers who use the HLAN are highly, if not completely, computer dependent. Employees use their computers as their pens and paper, calculators, drafting tables and communication devices. Fifty eight percent of the survey respondents predict 90 to 100% loss in productivity if they had no access to a computer. Additionally, 30% of the users felt they would have a 50 to 80% loss in productivity without computers; and more than 68 % use their computers between 4 and 8 hours per day. The profile also shows th at the software packages used most heavily are cc:Mail` the Windows version, Hanford Information, WordPerfece, Site Forms and Look-up. Use of Windows-based products is very high. Regarding the productivity tools that are seldom used, 49 % of the respondents say they ``never use`` the Hanford Help and Hints (HUH). The use of the external intemet by Hanford has shown a large increase. The survey indicates that users rate the intranet and the ability to access other sources of information as the fourth most important computer application. The Microsoft System Management Server (SMS 4) data show that more than 60% of the computers on the HLAN need replacement or upgrades to run the Windows 95 Operating System, which has been selected as the PHMC standard. Although data also show that 77% of the PHMC machines are running the current standard Windows for Workgroup version 3. 1 1, they do not have the memory and/or the hard disk space to upgrade to Windows 95. The survey results indicate that telephone system use is also high and regarded as a useful tool. Pager use is very high and

    2010-04-01

    In time-sensitive environments, such as DHS emergency operations centers (EOCs), it is imperative for decision makers to rapidly understand and address key logical relationships that exist between tasks, entities, and events, even as conditions fluctuate. These relationships often have important temporal characteristics, such as tasks that must be completed before others can be started (e.g., buses must be transported to an area before an evacuation process can begin). Unfortunately, traditional temporal display methods, such as mission timelines, typically reveal only rudimentary event details and fail to support user understanding of and reasoning about critical temporal constraints and interrelationships across multiple mission components. To address these shortcomings, we developed a visual language to enhance temporal data displays by explicitly and intuitively conveying these constraints and relationships to decision makers. In this paper, we detail these design strategies and describe ongoing evaluation efforts to assess their usability and effectiveness to support decision-making tasks in complex, time-sensitive environments. We present a case study in which we applied our visual enhancements to a timeline display, improving the perception of logical relationships among events in a Master Scenario Event List (MSEL). These methods reduce the cognitive workload of decision makers and improve the efficacy of identification.

    Leprosy is a debilitating, infectious disease caused by Mycobacterium leprae. Despite the availability of multidrug therapy, transmission is unremitting. Thus, early identification of M. leprae infection is essential to reduce transmission. The immune response to M. leprae is determined by host genetics, resulting in paucibacillary (PB) and multibacillary (MB) leprosy associated with dominant cellular or humoral immunity, respectively. This spectral pathology of leprosy compels detection of immunity to M. leprae to be based on multiple, diverse biomarkers. In this study we have applied quantitative user friendly lateral flow assays (LFAs) for four immune markers (anti-PGL-I antibodies, IL-10, CCL4 and IP-10) for whole blood samples from a longitudinal BCG vaccination field-trial in Bangladesh. Different biomarker profiles, in contrast to single markers, distinguished M. leprae infected from non-infected test groups, patients from household contacts (HHC) and endemic controls (EC), or MB from PB patients. The test protocol presented in this study merging detection of innate, adaptive cellular as well as humoral immunity, thus provides a convenient tool to measure specific biomarker profiles for M. leprae infection and leprosy utilizing a field-friendly technology.

    Smart phones are changing health communication for Americans. User-centered production of a mobile application for sun protection is reported. Focus groups (n = 16 adults) provided input on the mobile application concept. Four rounds of usability testing were conducted with 22 adults to develop the interface. An iterative programming procedure moved from a specification document to the final mobile application, named Solar Cell. Adults desired a variety of sun protection advice, identified few barriers to use and were willing to input personal data. The Solar Cell prototype was improved from round 1 (seven of 12 tasks completed) to round 2 (11 of 12 task completed) of usability testing and was interoperable across handsets and networks. The fully produced version was revised during testing. Adults rated Solar Cell as highly user friendly (mean = 5.06). The user-centered process produced a mobile application that should help many adults manage sun safety.

    Full Text Available Usability of public administration websites is a key issue in the information society. Unfortunately, the web content is still difficult to use if not unusable in many websites. Developers seem to neglect basic principles of user centered design. Usability heuristics are valuable resources for both developers and evaluators during and after the development process. The purpose of this work is to extend and refine an existing set of heuristics in order to better address some user centered design issues. Previous studies revealed specific usability problems of municipal websites as well as some evaluation issues. Two heuristics were added that refer to user guidance and task support. The revised heuristics could better help evaluators to explain and developers to understand usability problems in municipal websites.

    2016-01-01

    We present here the methodology and results of the Operational Acceptance Test (OAT) performed on the new Kennedy Space Center (KSC) 50-MHz Doppler Radar Wind Profiler (DRWP). On day-of-launch (DOL), space launch vehicle operators have used data from the DRWP to invalidate winds in prelaunch loads and trajectory assessments due to the DRWP's capability to quickly identify changes in the wind profile within a rapidly-changing wind environment. The previous DRWP has been replaced with a completely new system, which needs to undergo certification testing before being accepted for use in range operations. The new DRWP replaces the previous three-beam system made of coaxial cables and a copper wire ground plane with a four-beam system that uses Yagi antennae with enhanced beam steering capability. In addition, the new system contains updated user interface software while maintaining the same general capability as the previous system. The new DRWP continues to use the Median Filter First Guess (MFFG) algorithm to generate a wind profile from Doppler spectra at each range gate. DeTect (2015) contains further details on the upgrade. The OAT is a short-term test designed so that end users can utilize the new DRWP in a similar manner to the previous DRWP during mission operations at the Eastern Range in the midst of a long-term certification process. This paper describes the Marshall Space Flight Center Natural Environments Branch's (MSFC NE's) analyses to verify the quality and accuracy of the DRWP's meteorological data output as compared to the previous DRWP. Ultimately, each launch vehicle program has the responsibility to certify the system for their own use.

    Full Text Available Objective: To reveal the clinical and epidemiological characteristics of patients diagnosed with leprosy between the years 2007 and 2008, in a Family Primary Healthcare Unit in the city of Fortaleza-CE, Brazil.Methods: Documentary, quantitative and descriptive study. The research sample consisted of all medical records of patients examined and diagnosed with leprosy in the period from 2007 to 2008, totaling an amount of 55. Data was transcribed, tabulated, numbered and presented in tables and charts. Results: It was observed a concentration of cases in economically active age group; females (37 - 67%; race brown (36 - 65.5%; low schooling level, mostly incomplete primary education (25 - 45.5%. The cure rate in 2007 was 95.5% (21 cases and, in 2008, 57.2% (19 cases. The number of cases with multibacillary clinical forms was high, revealing the late diagnosis, leading to maintained transmission of the disease. Conclusion: Understanding the epidemiological profile and clinical characteristics of patients diagnosed with leprosy is of fundamental importance for the development of strategies directed towards this group, seeking public policies that meet the needs of health professionals and strengthen the activities of grievance prevention and health promotion among the population.

    Enclosed herein is our HWCMO user manual. This manual constitutes the final report for our NASA/PDC grant, NASA NAG5-8730, "Routine High Resolution Forecasts/Analysis for the Pacific Disaster Center". Since the beginning of the grant, we have routinely provided experimental high resolution forecasts from the RSM/MSM for the Hawaii Islands, while working to upgrade the system to include: (1) a more robust input of NCEP analyses directly from NCEP; (2) higher vertical resolution, with increased forecast accuracy; (3) faster delivery of forecast products and extension of initial 1-day forecasts to 2 days; (4) augmentation of our basic meteorological and simplified fireweather forecasts to firedanger and drought forecasts; (5) additional meteorological forecasts with an alternate mesoscale model (MM5); and (6) the feasibility of using our modeling system to work in higher-resolution domains and other regions. In this user manual, we provide a general overview of the operational system and the mesoscale models as well as more detailed descriptions of the models. A detailed description of daily operations and a cost analysis is also provided. Evaluations of the models are included although it should be noted that model evaluation is a continuing process and as potential problems are identified, these can be used as the basis for making model improvements. Finally, we include our previously submitted answers to particular PDC questions (Appendix V). All of our initially proposed objectives have basically been met. In fact, a number of useful applications (VOG, air pollution transport) are already utilizing our experimental output and we believe there are a number of other applications that could make use of our routine forecast/analysis products.

    Full Text Available BACKGROUND Empyema Thoracis (ET, the accumulation of pus in pleural cavity due to infective origin, is a perpetual clinical entity since Hippocratic era. The incidence and prevalence varies depending on different countries, type of infections, age and immune status of the host. OBJECTIVE To study profile of ET cases in relation to demography, clinical features, imaging, bacteriological status and treatment among patients admitted to Pulmonary Medicine Department, SCBMCH, Cuttack, Odisha. MATERIALS AND METHODS One hundred cases of ET were included in the study prospectively with detailed history, meticulous physical examination, necessary imaging, sputum/pleural fluid Gram and AFB staining, AFB culture and aerobic culture sensitivity followed by specific treatment. RESULTS Majority ET cases belonged to ages between 21-70 yrs. with relatively higher occurrence in young and middle ages, affecting more commonly males (87%, farmers (36%, diabetics (22% and alcoholics (22%. There was no significant association of any hemithorax among tubercular empyemas (Right 49%: Left 45%, whereas involvement of right hemithorax was significantly higher than left in non-tubercular empyemas (Right 63%: Left 26%. Free ET was seen in 67% of cases, encysted ET in 33% cases and underlying lung parenchymal lesions in 62% cases. Pleural pus was thin in 66% cases and thick in 34% (Tubercular cases. Gram staining of pleural fluid showed no bacteria in 82% cases, whereas it revealed growth on aerobic culture in 41% of cases. Tuberculosis was most common cause of empyema in 73% cases (Inclusive MDR-TB 2.7%, where Definite TB-ET was 15.1%, Probable TB-ET 84.9% and super infection predominantly due to pseudomonas was 13.6%. In contrast, Non-TB-ET was 27%, in which staphylococcus aureus (33.3% was the major isolate followed by Ps. Aeruginosa and Esch. Coli (20% each on aerobic culture. Thoracocentesis was performed in 15% cases, ICTD in 84% cases, decortication in 4% cases and

    Full Text Available Background: Trauma center profiling is commonly performed with Standardized Mortality Ratios (SMRs. However, comparison of SMRs across trauma centers with different case mix can induce confounding leading to biased trauma center ranks. We hypothesized that Regression-Adjusted Mortality (RAM estimates would provide a more valid measure of trauma center performance than SMRs. Objective: Compare trauma center ranks generated by RAM estimates to those generated by SMRs. Materials and Methods: The study was based on data from a provincial Trauma Registry (1999-2006; n = 88,235. SMRs were derived as the ratio of observed to expected deaths using: (1 the study population as an internal standard, (2 the US National Trauma Data Bank as an external standard. The expected death count was calculated as the sum of mortality probabilities for all patients treated in a hospital conditional on the injury severity score, the revised trauma score, and age. RAM estimates were obtained directly from a hierarchical logistic regression model. Results: Crude mortality was 5.4% and varied between 1.3% and 13.5% across the 59 trauma centers. When trauma center ranks from internal SMRs and RAM were compared, 49 out of 59 centers changed rank and six centers changed by more than five ranks. When trauma center ranks from external SMRs and RAM were compared, 55 centers changed rank and 17 changed by more than five ranks. Conclusions: The results of this study suggest that the use of SMRs to rank trauma centers in terms of mortality may be misleading. RAM estimates represent a potentially more valid method of trauma center profiling.

    Full Text Available Background: Population-based surveys demonstrate cannabis users are more likely to use both illicit and licit substances, compared with non-cannabis users. Few studies have examined the substance use profiles of cannabis users referred for treatment. Coexisting mental health symptoms and underlying cannabis-related beliefs associated with these profiles remains unexplored.Methods: Comprehensive drug use and dependence severity (Severity of Dependence Scale- Cannabis [SDS-C] data were collected on a sample of 826 cannabis users referred for treatment. Patients completed the General Health Questionnaire (GHQ-28, Cannabis Expectancy Questionnaire (CEQ, and Cannabis Refusal Self-Efficacy Questionnaire (CRSEQ and Positive Symptoms and Manic-Excitement subscales of the Brief Psychiatric Rating Scale (BPRS. Latent class analysis (LCA was performed on last month use of drugs to identify patterns of multiple drug use. Mental health comorbidity and cannabis beliefs were examined by identified drug use pattern.Results: A three-class solution provided the best fit to the data- (1 Cannabis and tobacco users (n = 176, (2 Cannabis, tobacco, and alcohol users (n = 498, and (3 wide-ranging substance users (n = 132. Wide-ranging substance users (3 reported higher levels of cannabis dependence severity, negative cannabis expectancies, lower opportunistic and emotional relief self-efficacy, higher levels of depression and anxiety, and higher manic-excitement and positive psychotic symptoms.Conclusion: In a sample of cannabis users referred for treatment, wide-ranging substance use was associated with elevated risk on measures of cannabis dependence, comorbid psychopathology and dysfunctional cannabis cognitions. These findings have implications for cognitive-behavioural assessment and treatment.

MSM IDUs were compared to other male IDUs using bivariate and multivariate procedures (logistic regression and answer tree analysis with the CHAID algorithm. Among the 709 male IDUs, 187 (26.4% reported ever having had sex with other men, while only 37 reported sex with other men in the previous six months. MSM IDUs were more likely to be unemployed (OR = 2.3, to have injected tranquilizers (OR = 3.6, and to be HIV-seropositive (OR = 2.1, compared to other male IDUs. Male same-sex relations in this subgroup appear to be associated with strategies to finance drug consuming habits, including sex for drugs with occasional female partners or obtaining injection paraphernalia from occasional sex partners. Further studies should focus on this especially vulnerable subgroup of IDUs, due to the bidirectional and complex interrelationships between their drug injecting habits and sexual risk behaviors.

    Full Text Available At-risk families live under circumstances that hinder their parenting competences, compromising their ability to fulfill their children’s needs appropriately. The complex and multiple-source nature of the adversities that they endure makes family preservation interventions challenging. Because their efficacy largely depends on the extent to which interventions fit participants’ needs and characteristics, the aims of this study were to draw the sociodemographic (individual, family, economic, labor, and child-related variables and psychosocial profile (negative life events, parenting stress, and psychological distress symptomatology of Spanish and Portuguese family preservation users while testing the inter-country differences. The results showed that the majority of participants had a low educational level, were unemployed, and were poor. Spanish and Portuguese participants had suffered an average of 5 and 4 negative life events over the past 3 years, respectively, with a high emotional impact. The most common were labor precariousness and economic hardship. Clinical levels of parenting stress were found in 48.1% of the Spanish participants and 39.1% of the Portuguese participants. An important proportion of the participants had clinical levels of psychological distress (Spain = 71.9%; Portugal = 45.8%, indicating the presence of mental health problems. Families’ support needs are discussed and guidelines for interventions aimed at improving parents’ and children’s well-being are outlined.

    Full Text Available The use of modern educational technology methods has become an important area of research in order to support learning as well as collaboration. This is especially evident with the rise of internet and web 2.0 platforms that have transformed users’ role from mere content consumers to fully content consumers-producers. Furthermore, people engaged in collaborative learning capitalize on one another’s resources and skills, unlike individual learning. This paper proceeds with a categorization of the main tools and functions that characterize the personalization learning aspect, in order to discuss their trade-offs with collaborative learning systems. It proposes a framework of a personalized information research (IR within a collaborative learning system, incorporating the characterization of the research type carried by the query, as well as modeling and constructing semantic users’ profiles. We use the context of the user query into a prediction mechanism of the search type, based on a previous identification of users’ levels and interests. The paper is concluded by presenting experiment results, revealing that the use of the subject ontology extension approach satisfyingly contributes to improvement in the accuracy of system recommendations.

    2016-01-01

    Despite of various benefits such as a convenience and efficiency, home healthcare systems have some inherent security risks that may cause a serious leak on personal health information. This work presents a Secure User Profiling Structure which has the patient information including their health information. A patient and a hospital keep it at that same time, they share the updated data. While they share the data and communicate, the data can be leaked. To solve the security problems, a secure communication channel with a hash function and an One-Time Password between a client and a hospital should be established and to generate an input value to an OTP, it uses a dual hash-function. This work presents a dual hash function-based approach to generate the One-Time Password ensuring a secure communication channel with the secured key. In result, attackers are unable to decrypt the leaked information because of the secured key; in addition, the proposed method outperforms the existing methods in terms of computation cost.

    Modern reversible contraceptive methods currently approved in Vanuatu are: oral hormonal contraceptives (OCs), the intrauterine device (IUD), and condoms. These are used by about 9% of all women in childbearing age. A study was undertaken to determine profiles of average current modern FP users in order to identify some of the factors influencing FP use and facilitate better program management. FP records from 3 hospitals were reviewed in 1992, and user profiles were constructed in terms of age, parity, and length of use for the OC and the IUD (used nationally by 60% and 3)% of all modern methods users, respectively). The results involving 513 current OC and 438 IUD users showed that 61% of OC and 6% of IUD user groups were aged 22-30 years and had 2 or 3 children. The 1st finding was that few women with just 1 child use either OCs or the IUD; they represent a potentially under-served target group for the FP programs. Service providers could specifically counsel such women and their partner on planned parenthood and through targeted health education material. The 2nd finding was that the average length of use of the IUD was significantly longer than that of OCs. In a country where access to FP services is frequently difficult and having children (even for single women) socially acceptable, the decision to discontinue OCs is often made by default. In contrast, discontinuation of an IUD requires a more active decision to be made, usually to have another child or because of unacceptable side effects. Hence, the significantly shorter length of use of OCs compared to IUDs by FP users. This finding underlines the importance of promoting IUDs among parous women in Vanuatu. The FP user profiles can be valuable for program planners by identifying groups using FP services, and any significant differences in the pattern of use among acceptors. PMID:8356742

    Human-computer interaction and related areas of user experience (UX) research, such as human factors, workflow evaluation, and data visualization, are thus essential to presenting data in ways that can further the analysis of complex data sets such as those used in patient-centered research. However, a review of available data on the state of UX research as it relates to patient-centered research demonstrates a significant underinvestment and consequently a large gap in knowledge generation. In response, this report explores trends in funding and research productivity focused on UX and patient-centered research and then presents a set of recommendations to advance innovation at this important intersection point. Ultimately, the aim is to catalyze a community-wide dialogue concerning future directions for research and innovation in UX as it applies to patient-centered research.

    Health information technology (IT) has opened exciting avenues for capturing, delivering and sharing data, and offers the potential to develop cost-effective, patient-focused applications. In recent years, there has been a proliferation of health IT applications such as outpatient portals. Rigorous evaluation is fundamental to ensure effectiveness and sustainability, as resistance to more widespread adoption of outpatient portals may be due to lack of user friendliness. Health IT applications that integrate with the existing electronic health record and present information in a condensed, user-friendly format could improve coordination of care and communication. Importantly, these applications should be developed systematically with appropriate methodological design and testing to ensure usefulness, adoption, and sustainability. Based on our prior work that identified numerous information needs and challenges of HCT, we developed an experimental prototype of a health IT tool, the BMT Roadmap. Our goal was to develop a tool that could be used in the real-world, daily practice of HCT patients and caregivers (users) in the inpatient setting. Herein, we examined the views, needs, and wants of users in the design and development process of the BMT Roadmap through user-centered Design Groups. Three important themes emerged: 1) perception of core features as beneficial (views), 2) alerting the design team to potential issues with the user interface (needs); and 3) providing a deeper understanding of the user experience in terms of wider psychosocial requirements (wants). These findings resulted in changes that led to an improved, functional BMT Roadmap product, which will be tested as an intervention in the pediatric HCT population in the fall of 2015 (ClinicalTrials.govNCT02409121).

    Full Text Available Abstract Background Because of the increasing number of electronic resources, designing efficient tools to retrieve and exploit them is a major challenge. Some improvements have been offered by semantic Web technologies and applications based on domain ontologies. In life science, for instance, the Gene Ontology is widely exploited in genomic applications and the Medical Subject Headings is the basis of biomedical publications indexation and information retrieval process proposed by PubMed. However current search engines suffer from two main drawbacks: there is limited user interaction with the list of retrieved resources and no explanation for their adequacy to the query is provided. Users may thus be confused by the selection and have no idea on how to adapt their queries so that the results match their expectations. Results This paper describes an information retrieval system that relies on domain ontology to widen the set of relevant documents that is retrieved and that uses a graphical rendering of query results to favor user interactions. Semantic proximities between ontology concepts and aggregating models are used to assess documents adequacy with respect to a query. The selection of documents is displayed in a semantic map to provide graphical indications that make explicit to what extent they match the user's query; this man/machine interface favors a more interactive and iterative exploration of data corpus, by facilitating query concepts weighting and visual explanation. We illustrate the benefit of using this information retrieval system on two case studies one of which aiming at collecting human genes related to transcription factors involved in hemopoiesis pathway. Conclusions The ontology based information retrieval system described in this paper (OBIRS is freely available at: http://www.ontotoolkit.mines-ales.fr/ObirsClient/.

    NASAs LSP customers and the future SLS program rely on observations of upper-level winds for steering, loads, and trajectory calculations for the launch vehicles flight. On the day of launch, the 45th Weather Squadron (45 WS) Launch Weather Officers (LWOs) monitor the upper-level winds and provide forecasts to the launch team via the AMU-developed LSP Upper Winds tool for launches at Kennedy Space Center (KSC) and Cape Canaveral Air Force Station. This tool displays wind speed and direction profiles from rawinsondes released during launch operations, the 45th Space Wing 915-MHz Doppler Radar Wind Profilers (DRWPs) and KSC 50-MHz DRWP, and output from numerical weather prediction models.The goal of this task was to splice the wind speed and direction profiles from the 45th Space Wing (45 SW) 915-MHz Doppler radar Wind Profilers (DRWPs) and KSC 50-MHz DRWP at altitudes where the wind profiles overlap to create a smooth profile. In the first version of the LSP Upper Winds tool, the top of the 915-MHz DRWP wind profile and the bottom of the 50-MHz DRWP were not spliced, sometimes creating a discontinuity in the profile. The Marshall Space Flight Center (MSFC) Natural Environments Branch (NE) created algorithms to splice the wind profiles from the two sensors to generate an archive of vertically complete wind profiles for the SLS program. The AMU worked with MSFC NE personnel to implement these algorithms in the LSP Upper Winds tool to provide a continuous spliced wind profile.The AMU transitioned the MSFC NE algorithms to interpolate and fill data gaps in the data, implement a Gaussian weighting function to produce 50-m altitude intervals in each sensor, and splice the data together from both DRWPs. They did so by porting the MSFC NE code written with MATLAB software into Microsoft Excel Visual Basic for Applications (VBA). After testing the new algorithms in stand-alone VBA modules, the AMU replaced the existing VBA code in the LSP Upper Winds tool with the new

    Landsat data have been produced, archived, and distributed by the U.S. Geological Survey (USGS) since 1972. Scientists and users rely on these data for historical study of land surface change, but shoulder the burden of post-production processing to create applications-ready data sets. In compliance with guidelines established through the Global Climate Observing System, USGS has embarked on production of higher-level Landsat data products to support land surface change study. Terrestrial variables such as surface reflectance and land surface temperature will be offered as Climate Data Records (CDR). Derivations of spectral indices from surface reflectance are also produced, to further ease user application in land remote sensing science. Higher level products, such as leaf area index, burned area extent, snow covered area, and surface water extent representing Essential Climate Variables (ECV) will be available soon.

    Full Text Available User acceptance of myoelectric forearm prostheses is currently low. Awkward control, lack of feedback, and difficult training are cited as primary reasons. Recently, researchers have focused on exploiting the new possibilities offered by advancements in prosthetic technology. Alternatively, researchers could focus on prosthesis acceptance by developing functional requirements based on activities users are likely to perform. In this article, we describe the process of determining such requirements and then the application of these requirements to evaluating the state of the art in myoelectric forearm prosthesis research. As part of a needs assessment, a workshop was organized involving clinicians (representing end users, academics, and engineers. The resulting needs included an increased number of functions, lower reaction and execution times, and intuitiveness of both control and feedback systems. Reviewing the state of the art of research in the main prosthetic subsystems (electromyographic [EMG] sensing, control, and feedback showed that modern research prototypes only partly fulfill the requirements. We found that focus should be on validating EMG-sensing results with patients, improving simultaneous control of wrist movements and grasps, deriving optimal parameters for force and position feedback, and taking into account the psychophysical aspects of feedback, such as intensity perception and spatial acuity.

    Full Text Available The youth, especially school going children, are the future of any society. It is therefore important that children should receive adequate healthcare support at an early age in order to strive to preserve and ensure better education and welfare of the children and continuity in societal success. Despite the strategic initiatives that aim at improving the general health of school going children, such as South Africa’s Integrated School Health Policy, there still exist challenges in support programmes meant to alleviate the barriers to effective healthcare towards improved education for the school children. Advances in ICT enable a fundamental redesign of healthcare processes based on the use and integration of electronic communication at all levels. New communication technologies can support a transition from institution centric to user-centric applications. This paper defines key principles and challenges for designers, policy makers, and evaluators of user-centred technologies for healthcare in schools. The paper employs the User Experience Management Model (UXM2 to review the current and emerging trends, and highlights challenges related to the design of a typical m-ICT application that supports delivery of healthcare in schools. The paper reaches conclusions for next steps that will advance the domain.

    We study the emission of the hydrogen Lyman-a line in the quiet Sun, its center-to-limb variation (CLV), and its radiance distribution. We also compare quasi-simultaneous Ly-a and Ly-b line profiles. We used the high spectral and spatial resolution of the SUMER spectrometer and completed raster scans at various locations along the disk. For the first time, we used a method to reduce the incoming photon flux to a 20%-level by partly closing the aperture door. We also performed a quasi-simultaneous observation of both Ly-a and Ly-b at Sun center in sit-and-stare mode. We infer the flow characteristic in the Ly-a map from variations in the calibrated 1206 Si III line centroids. We present the average profile of Ly-a, its radiance distribution, its CLV behaviour, and the signature of flows on the line profiles. Little CLV and no limb brightening are observed in the profiles of the Ly-a line. In contrast to all other lines of the Lyman series, which have a stronger red-horn, Ly-a has a dominating blue-horn asymmet...

    Purpose To involve elderly people during the development of a mobile interface of a monitoring system that provides feedback to them regarding changes in physical functioning and to test the system in a pilot study. Methods and participants The iterative user-centered development process consisted of the following phases: (1) selection of user representatives; (2) analysis of users and their context; (3) identification of user requirements; (4) development of the interface; and (5) evaluation of the interface in the lab. Subsequently, the monitoring and feedback system was tested in a pilot study by five patients who were recruited via a geriatric outpatient clinic. Participants used a bathroom scale to monitor weight and balance, and a mobile phone to monitor physical activity on a daily basis for six weeks. Personalized feedback was provided via the interface of the mobile phone. Usability was evaluated on a scale from 1 to 7 using a modified version of the Post-Study System Usability Questionnaire (PSSUQ); higher scores indicated better usability. Interviews were conducted to gain insight into the experiences of the participants with the system. Results The developed interface uses colors, emoticons, and written and/or spoken text messages to provide daily feedback regarding (changes in) weight, balance, and physical activity. The participants rated the usability of the monitoring and feedback system with a mean score of 5.2 (standard deviation 0.90) on the modified PSSUQ. The interviews revealed that most participants liked using the system and appreciated that it signaled changes in their physical functioning. However, usability was negatively influenced by a few technical errors. Conclusion Involvement of elderly users during the development process resulted in an interface with good usability. However, the technical functioning of the monitoring system needs to be optimized before it can be used to support elderly people in their self-management. PMID

  11. NONLINEAR FORCE PROFILE USED TO INCREASE THE PERFORMANCE OF A HAPTIC USER INTERFACE FOR TELEOPERATING A ROBOTIC HAND

    MODIFIED PAPER TITLE AND ABSTRACT DUE TO SLIGHTLY MODIFIED SCOPE: TITLE: Nonlinear Force Profile Used to Increase the Performance of a Haptic User Interface for Teleoperating a Robotic Hand Natural movements and force feedback are important elements in using teleoperated equipment if complex and speedy manipulation tasks are to be accomplished in hazardous environments, such as hot cells, glove boxes, decommissioning, explosives disarmament, and space. The research associated with this paper hypothesizes that a user interface and complementary radiation compatible robotic hand that integrates the human hand’s anthropometric properties, speed capability, nonlinear strength profile, reduction of active degrees of freedom during the transition from manipulation to grasping, and just noticeable difference force sensation characteristics will enhance a user’s teleoperation performance. The main contribution of this research is in that a system that concisely integrates all these factors has yet to be developed and furthermore has yet to be applied to a hazardous environment as those referenced above. In fact, the most prominent slave manipulator teleoperation technology in use today is based on a design patented in 1945 (Patent 2632574) [1]. The robotic hand/user interface systems of similar function as the one being developed in this research limit their design input requirements in the best case to only complementing the hand’s anthropometric properties, speed capability, and linearly scaled force application relationship (e.g. robotic force is a constant, 4 times that of the user). In this paper a nonlinear relationship between the force experienced between the user interface and the robotic hand was devised based on property differences of manipulation and grasping activities as they pertain to the human hand. The results show that such a relationship when subjected to a manipulation task and grasping task produces increased performance compared to the

    The process of engineering design requires the product development team to balance the needs and limitations of many stakeholders, including those of the user, regulatory organizations, and the designing institution. This is particularly true in medical device design, where additional consideration must be given for a much more complex user-base that can only be accessed on a limited basis. Given this inherent challenge, few projects exist that consider design domain concepts, such as aspects of a detailed design, a detailed view of various stakeholders and their capabilities, along with the user-needs simultaneously. In this paper, we present a novel information model approach that combines a detailed model of design elements with a model of the design itself, customer requirements, and of the capabilities of the customer themselves. The information model is used to facilitate knowledge capture and automated reasoning across domains with a minimal set of rules by adopting a terminology that treats customer and design specific factors identically, thus enabling straightforward assessments. A uniqueness of this approach is that it systematically provides an integrated perspective on the key usability information that drive design decisions towards more universal or effective outcomes with the very design information impacted by the usability information. This can lead to cost-efficient optimal designs based on a direct inclusion of the needs of customers alongside those of business, marketing, and engineering requirements. Two case studies are presented to show the method's potential as a more effective knowledge management tool with built-in automated inferences that provide design insight, as well as its overall effectiveness as a platform to develop and execute medical device design from a holistic perspective.

    Full Text Available Viral marketing seeks to maximize the spread of a campaignthrough an online social network, often targeting influential nodes with highcentrality. In this article, we analyze behavioral aspects of influentialusers in trust-based product reviews communities, quantifying emotionalexpression, helpfulness, and user activity level. We focus on two independentproduct review communities, Dooyoo and Epinions, in whichusers can write product reviews and define trust links to filter productrecommendations. Following the patterns of social contagion processes, wemeasure user social influence by means of the k-shell decomposition of trustnetworks. For each of these users, we apply sentiment analysis to extracttheir extent of positive, negative, and neutral emotional expression. Inaddition, we quantify the level of feedback they received in their reviews,the length of their contributions, and their level of activity over theirlifetime in the community. We find that users of both communities exhibit alarge heterogeneity of social influence, and that helpfulness votes and ageare significantly better predictors of the influence of an individual thansentiment. The most active of the analyzed communities shows a particularstructure, in which the inner core of users is qualitatively different fromits periphery in terms of a stronger positive and negative emotionalexpression. These results suggest that both objective and subjective aspectsof reviews are relevant to the communication of subjective experience.

    Full Text Available Under the national educational policy of Nine-Year Integrated Curriculum, elementary and junior high school teachers are expected to design their own instructional materials, and to teach their courses which could be linked to students’ daily lives. The policy also allocates funding to create a variety of web-based instructional resource systems in order to assist these teachers in preparing their classes. Upon the basis of a user-centered design approach, this study is aimed at constructing a set of suggestions of planning, designing, and developing a web-based instructional resource system for the homeland education. This research team takes Nei-Li area in Taiwan as an example to develop such a system, and constructs a user-centered design model. The study results indicate that, unlike the traditional instructional design approach, the proposed model takes into account the user’s needs, the capability of the project team, the resource availability for implementation, the national educational reform policy, the development of information technology industry, and the socio-cultural context of a community at the initial phase. In addition, the development process is divided into two courses, one for contents design while the other for system construction, both of which are implemented at the same time.

    2016-01-01

    This paper presents results of the new Kennedy Space Center (KSC) 50-MHz Doppler Radar Wind Profiler (DRWP) Operational Acceptance Test (OAT). The goal of the OAT was to verify the data quality of the new DRWP against the performance of the previous DRWP in order to use wind data derived by the new DRWP for space launch vehicle operations support at the Eastern Range. The previous DRWP was used as a situational awareness asset for mission operations to identify rapid changes in the wind environment that weather balloons cannot depict. The Marshall Space Flight Center's Natural Environments Branch assessed data from the new DRWP collected during Jan-Feb 2015 against a specified set of test criteria. Data examination verified that the DRWP provides complete profiles every five minutes from 1.8-19.5 km in vertical increments of 150 m. Analysis of 49 concurrent DRWP and balloon profiles presented root mean square wind component differences around 2.0 m/s. Evaluation of the DRWP's coherence between five-minute wind pairs found the effective vertical resolution to be Nyquist-limited at 300 m for both wind components. In addition, the sensitivity to rejecting data that do not have adequate signal was quantified. This paper documents the data, quality control procedures, methodology, and results of each analysis.

    This paper presents the process used by the Marshall Space Flight Center Natural Environments Branch (EV44) to quality control (QC) data from the Kennedy Space Center's 50-MHz Doppler Radar Wind Profiler for use in vehicle wind loads and steering commands. The database has been built to mitigate limitations of using the currently archived databases from weather balloons. The DRWP database contains wind measurements from approximately 2.7-18.6 km altitude at roughly five minute intervals for the August 1997 to December 2009 period of record, and the extensive QC process was designed to remove spurious data from various forms of atmospheric and non-atmospheric artifacts. The QC process is largely based on DRWP literature, but two new algorithms have been developed to remove data contaminated by convection and excessive first guess propagations from the Median Filter First Guess Algorithm. In addition to describing the automated and manual QC process in detail, this paper describes the extent of the data retained. Roughly 58% of all possible wind observations exist in the database, with approximately 100 times as many complete profile sets existing relative to the EV44 balloon databases. This increased sample of near-continuous wind profile measurements may help increase launch availability by reducing the uncertainty of wind changes during launch countdown

    2016-01-01

    The late-type stellar population in the Galactic Center was first predicted to reside in a dynamically relaxed cusp (power law slope ranging from 3/2 to 7/4). However, observations - which rely on models to correct for projection effects - have suggested a flat distribution instead. The need for this correction is due to the lack of information regarding the line-of-sight distances. With a two decade long baseline in astrometric measurements, we are now able to measure significant projected radial accelerations, six of which are newly reported here, that directly constrain line-of-sight distances. Here we present a statistical approach to take advantage of this information and more accurately constrain the shape of the radial density profile of the late-type stellar population in the Galactic Center.

    Full Text Available One aimed to identify the nutritional profile of children in a public daycare center in the city of Cuité-Paraíba, from the perspective of health surveillance. This is a cross-sectional, exploratory-descriptive, field study with a quantitative approach, performed in 2011, with 55 children from 6 to 60 months of life, assisted full time in a public daycare center, who met the selection criteria: be attending the daycare center; and not present any disability. One used for evaluation the anthropometric measurements of weight, height and Body Mass Index, according to the growth curve suggested by the Ministry of Health. One identified that 96.4% had adequate nutritional status, however, 7.3% had overweight risk and 3.6% underweight risk, especially girls. It is important to raise managers’, professionals’ and parents’ awareness about the health surveillance of children in daycare centers for identification and intervention against nutritional changes, encouraging an adequate child growth.

    Full Text Available Abstract Background Analysis of the plethora of metabolites found in the NMR spectra of biological fluids or tissues requires data complexity to be simplified. We present a graphical user interface (GUI for NMR-based metabonomic analysis. The "Metabonomic Package" has been developed for metabonomics research as open-source software and uses the R statistical libraries. Results The package offers the following options: Raw 1-dimensional spectra processing: phase, baseline correction and normalization. Importing processed spectra. Including/excluding spectral ranges, optional binning and bucketing, detection and alignment of peaks. Sorting of metabolites based on their ability to discriminate, metabolite selection, and outlier identification. Multivariate unsupervised analysis: principal components analysis (PCA. Multivariate supervised analysis: partial least squares (PLS, linear discriminant analysis (LDA, k-nearest neighbor classification. Neural networks. Visualization and overlapping of spectra. Plot values of the chemical shift position for different samples. Furthermore, the "Metabonomic" GUI includes a console to enable other kinds of analyses and to take advantage of all R statistical tools. Conclusion We made complex multivariate analysis user-friendly for both experienced and novice users, which could help to expand the use of NMR-based metabonomics.

    2016-04-01

    This study sought to explore the effects of exposure to Facebook body ideal profile pictures and norm conforming comments on users' body image. In addition, the social identity and self-categorization theoretical frameworks were used to explore users' endorsement of a body ideal norm. A mock Facebook page was used to conduct a pretest posttest 2 × 2 between-group web-based experiment that featured body ideal profile pictures (body ideal vs. no body) and body ideal comments (conforming vs. nonconforming). Five hundred and one participants completed the experiment and passed all manipulation checks. Participants viewed pictures and comments on the status page and were able to leave their own comment before exiting. Results demonstrated no significant main effects. However, predispositional body satisfaction significantly moderated the relationship between body ideal pictures and body satisfaction. Most comments supported the body ideal norm. However, in support of self-categorization theory, participants exposed to nonconforming comments made nonconforming comments themselves significantly more than those exposed to conforming comments. The findings demonstrated the importance of continued body image research in social network sites, as well as the potential for self-categorization theory to guide such research. PMID:26991764

    We present radial velocity analysis for 20 solar neighborhood RR Lyrae and 3 Population II Cepheids. High-resolution spectra were observed with either TNG/SARG or VLT/UVES over varying phases. To estimate the center of mass (barycentric) velocities of the program stars, we utilized two independent methods. First, the 'classic' method was employed, which is based on RR Lyrae radial velocity curve templates. Second, we provide the new method that used absorption line profile asymmetry to determine both the pulsation and the barycentric velocities even with a low number of high-resolution spectra and in cases where the phase of the observations is uncertain. This new method is based on a least squares deconvolution (LSD) of the line profiles in order to an- alyze line asymmetry that occurs in the spectra of pulsating stars. By applying this method to our sample stars we attain accurate measurements (+- 2 kms^-1) of the pulsation component of the radial velocity. This results in determination of the barycentric velocity to within 5 kms^-1 even with a low number of high- resolution spectra. A detailed investigation of LSD profile asymmetry shows the variable nature of the project factor at different pulsation phases, which should be taken into account in the detailed spectroscopic analysis of pulsating stars.

    Full Text Available Objective: To investigate the nutritional profile and understand the dietary habits of patients in the HIPERDIA Program aiming to contribute to the discussion on disease prevention and health promotion in primary care. Methods: From August 2011 to February 2012, students and tutors of the “Programa de Educação pelo Trabalho para a Saúde” (PET-Saúde of the Federal University of Pará interviewed 125 individuals with hypertension and/ or diabetes registered in the Family Health Strategy of “Jardim Florestal” and “Mururé” in the municipality of Ananindeua, Pará state. We applied a structured questionnaire containing questions about socio-economic profile, clinical data, habits, and life style related to patients’ food consumption. Results: Among the respondents, 65.6% were diabetics and 84.8% were hypertensive. Most of the respondents (81.6% claimed that they had been following a diet to control hypertension or diabetes mellitus, especially with regard to salt, fat, and sugar reduction. Overweight (BMI greater than 24.9 kg/m² was a predominant factor in the population analyzed (73.6% of the respondents. Conclusion: The research participants were not following an adequate diet requirement. In this context, it is necessary to improve nutritional monitoring and implement socio-educational preventive measures in order to control chronic non-transmissible diseases, thus ameliorating people’s quality of life.

    Full Text Available Time banks (TBs have experienced significant growth in the last few years in Spain and have been incorporated in the agenda of political parties drawing the attention of national and international media as a solution to the economic crisis. Nevertheless, there is scant empirical evidence about this phenomenon in Spain. After describing the role of TBs in other countries, this paper examines the structure and management of TBs in Spain and develops a taxonomy of them. Additionally, it identifies the goals TBs pursue and the reasons why users join them. To do so, this paper uses a mixed-method approach consisting of in-depth interviews with 28 TB managers and an online survey of users (n=270. It concludes that TBs are a social-political project rather than a utilitarian-economic project, identifying differences between Spanish TBs and those in other countries.Los bancos de tiempo han ido ganando importancia en los últimos años, han sido incorporados en programas políticos, y están siendo objeto de atención por la prensa nacional e internacional como una solución a la crisis que atraviesa el país. Sin embargo, poco se sabe de este fenómeno en España. Este trabajo, tras identificar el papel que los bancos de tiempo han jugado en otros países, analiza tanto la estructura y gestión de los bancos, ofreciendo una taxonomía de los mismos, además de examinar los fines para los que se crean y por los que se participa en ellos. Para ello, se recurre a un método mixto: entrevistas en profundidad con 28 gestores de bancos de tiempo y una encuesta online a usuarios (n=270. Se concluye que el fenómeno de los bancos de tiempo en España tiene más de proyecto social-político que económico-utilitario y que mantiene algunas particularidades que lo diferencian de otros países.

    Full Text Available Background: Use of tobacco among alcohol dependent population is quite frequent. This co-morbidity increases the risk for various diseases. Understanding the pattern of tobacco use with co-morbid alcohol use may help in planning appropriate prevention/treatment strategies. The study aimed at examining the profile and pattern of nicotine use among alcohol dependent patients visiting a tertiary care treatment center in North India. Materials and Methods: Male patients fulfilling diagnostics and statistical manual of mental disorder fourth edition, criteria for nicotine and alcohol diagnostics and statistical dependence, attending the out-patient department of the tertiary care treatment center were recruited after obtaining informed consent. The socio-demographic profile, drug use history, nicotine associated health problems and general health problem were recorded. Motivation to stop tobacco use was assessed qualitatively using the direct questions about their interest and intentions to quit. Results: A total of 150 subjects were included in the study. The mean age of the study sample was 37.6 ± 10.44 years. Tobacco was reported as the gateway drug in 90% of the cases. Exclusive bidi use reported in 42% of the subjects. Mean duration of bidi and co-morbid alcohol use was higher than cigarette or smokeless tobacco use. Self-reported health problems associated with nicotine use and general health was reported by 41% and 39% of the subjects. Unsuccessful past quit attempts was present in 85% cases. More than 90% of subjects remained interested in quitting the tobacco use. An increased liver enzyme (aspartate transaminase, alanine transaminase and gamma-glutamyl transferase were observed in 43, 32 and 47% of the cases. Conclusion: The results suggest the nicotine and alcohol dependent patients represent a separate population requiring higher attention from the treating physician.

    Objective: Investigations of injecting drug users (IDUs have suggested that the social context may influence high-risk behaviours in this population. The aim of this study was to describe knowledge, attitudes and behaviours of IDUs attending public drug-treatment centres in our area.

    Study design and methods: A cross-sectional survey was conducted between July 2002 and February 2004, enrolling 607 drug users attending four public drug-treatment centres in the Palermo area. Two of them were located inside the urban area, whereas the other two were in rural districts near the city. All participants answered an anonymous questionnaire concerning social and demographic characteristic and potential high-risk behaviours.

    Results: IDUs living in urban context have a higher educational level, higher number of sexual partners, as well as a lower prevalence of exchanging sex for drugs. Conversely, IDUs living in suburban/rural context are less likely to share syringes and more likely to have used light drugs in the past. Suburban/rural IDUs drink more alcohol but smoke less cigarettes/day, although both groups are strong smokers.

    Conclusions: The results suggest that public drug-treatment centres should take in consideration the adoption of specific programs targeting specific groups, in line with the profile and needs of the subjects in each context in order to promote approaches leading to risk reduction.

  1. Building social participation with a support group users: challenges of care qualification in a Psychosocial Care Center (CAPS

    Full Text Available The literature points out a lack of studies describing practical experiences approaching the role of social participation, even though, the subject Brazilian Health System (SUS as a principle is valued by theoretical-conceptual works. The lack of studies is especially observed in mental health care services, where the existing studies focus on the users’ management engagement as part of psychosocial rehabilitation. Thus, this article introduces an experience developed in a Center for Psycho-Social Attention (CAPS, in the state of Mato Grosso do Sul, aiming to address the issue of social participation in care qualification, in accordance to legislation and technical standards. Thisstudy focused on two types of sources. 1 Internship Final Report of a Psycology Student including 54 sessions of a support group, 2 technical and legal documents concerning the SUS and the National Mental Health Policy and Humanization. The service aspects were analyzed through technical and legislative foundations - focusing the needs and claims on group discussions, classified as structure and process, used to assess the health care quality. Most concerns were listed on normative Ordinances and Regulations. Achieving social participation was not an institutional premise and, among the main difficulties was the medical/outpatient centered model and the representation of “crazy”/”CAPS users” as incapable. It requires: i integration of “clinic” and “politics”; ii intensification of interdisciplinary and psychological care; iii respect the citizenship of mental health users, and, finally, iv that the collective participation spaces do not exhaust themselves. Therefore, the collective participation spaces need practical recommendations in order to improve the structures and work processes and meet the users’ needs.

    Little is understood regarding medicinal marijuana dispensary users. We sought to characterize socio-demographics and reasons for medicinal marijuana use among medical cannabis dispensary patients in Rhode Island. Participants (n=200) were recruited from one of two Compassion Centers in Rhode Island and asked to participate in a short survey, which included assessment of pain interference using the Brief Pain Inventory (BPI). The majority of participants were male (73%), Caucasian (80%), college educated (68%), and had health insurance (89%). The most common reason for medicinal marijuana use was determined to be chronic pain management. Participants were more likely to have BPI pain interference scores of > 5 if they were older (OR: 1.36, 95% CI: 1.04-1.78) or reported using cannabis as a substitute for prescription medications (OR: 2.47, 95% CI: 1.23-4.95), and were less likely to have interference scores of >5 if they had higher income levels (OR: 0.53, 95% CI: 0.40-0.70) or reported having ever received treatment for an alcohol use disorder. One-fifth of participants had a history of a drug or alcohol use disorder. Most participants report that medicinal cannabis improves their pain symptomology, and are interested in alternative treatment options to opioid-based treatment regimens. PMID:25715068

Data from western India is lacking. Aim : To present the clinical profile of PHPT from western India. Settings and Design : This retrospective study was conducted at a tertiary care referral center. Materials and Methods : We analyzed the clinical presentation, biochemical, radiological features, and operative findings in adult patients with PHPT (1986-2008 and compared with our published data of children and adolescent patients with PHPT. Statistical Analysis : was done with SPSS 16 software. Results : Seventy-nine patients (F: M-2:1 with age ranging from 21 to 55 years (mean 33.5±8.82 were analyzed. Skeletal manifestations (75.5%, renal calculi (40.5% and proximal muscle weakness (45.5% were the most common symptoms of presentation with mean duration of symptoms being 33.70 (median: 24, range 1-120 months. Biochemical features included hypercalcemia (total corrected calcium 12.55±1.77 mg/dl, low inorganic phosphorus (1.81±0.682 mg/dl, elevated total alkaline phosphatase (mean: 762.2; median: 559; range: 50-4930IU/L and high parathyroid hormone (PTH (mean±SD: 866.61±799.15; median: 639.5; range: 52-3820 pg/ml. Preoperative localization was achieved in 74 patients and single adenoma was found during surgery in 72 patients. Hungry bone disease was seen in 30.3% and transient hypoparathyroidism developed in 62% patients. In comparison to PHPT in children there were no significant differences with regard to clinical, laboratory and radiological features. Conclusions : PHPT in western India is symptomatic disorder with skeletal and renal mani-festations at a much younger age. Clinical profile of PHPT in children is similar to that of adults.

    Innovative molecular diagnostics deployed in the clinic enable new ways to stratify patients into appropriate treatment regimens. These approaches may resolve a major challenge for early-phase clinical trials, which is to recruit patients who, while having failed previous treatments, may nevertheless respond to molecularly targeted drugs. We report the findings of a prospective, single-center study conducted in patients with diverse refractory cancers who underwent comprehensive genomic profiling (CGP; next-generation sequencing, 236 genes). Of the 500 patients enrolled, 188 (37.6%) received either matched (N = 122/188, 65%) or unmatched therapy (N = 66/188, 35%). The most common reasons that patients were not evaluable for treatment included insufficient tissue, death, or hospice transfer. The median number of molecular alterations per patient was five (range, 1-14); median number of prior therapies, four. The most common diagnoses were ovarian cancer (18%), breast cancer (16%), sarcoma (13%), and renal cancer (7%). Of the 339 successfully profiled patients, 317 (93.5%) had at least one potentially actionable alteration. By calculating matching scores, based on the number of drug matches and genomic aberrations per patient, we found that high scores were independently associated with a greater frequency of stable disease ≥6 months/partial/complete remission [22% (high scores) vs. 9% (low scores), P = 0.024], longer time-to-treatment failure [hazard ratio (HR) = 0.52; 95% confidence interval (CI) = 0.36-0.74; P = 0.0003], and survival (HR = 0.65; 95% CI = 0.43-1.0; P = 0.05). Collectively, this study offers a clinical proof of concept for the utility of CGP in assigning therapy to patients with refractory malignancies, especially in those patients with multiple genomic aberrations for whom combination therapies could be implemented.

    The purpose of this work was to harmonize data acquisition and post-processing of single voxel proton MRS ((1) H-MRS) at 7 T, and to determine metabolite concentrations and the accuracy and reproducibility of metabolite levels in the adult human brain. This study was performed in compliance with local institutional human ethics committees. The same seven subjects were each examined twice using four different 7 T MR systems from two different vendors using an identical semi-localization by adiabatic selective refocusing spectroscopy sequence. Neurochemical profiles were obtained from the posterior cingulate cortex (gray matter, GM) and the corona radiata (white matter, WM). Spectra were analyzed with LCModel, and sources of variation in concentrations ('subject', 'institute' and 'random') were identified with a variance component analysis. Concentrations of 10-11 metabolites, which were corrected for T1 , T2 , magnetization transfer effects and partial volume effects, were obtained with mean Cramér-Rao lower bounds below 20%. Data variances and mean concentrations in GM and WM were comparable for all institutions. The primary source of variance for glutamate, myo-inositol, scyllo-inositol, total creatine and total choline was between subjects. Variance sources for all other metabolites were associated with within-subject and system noise, except for total N-acetylaspartate, glutamine and glutathione, which were related to differences in signal-to-noise ratio and in shimming performance between vendors. After multi-center harmonization of acquisition and post-processing protocols, metabolite concentrations and the sizes and sources of their variations were established for neurochemical profiles in the healthy brain at 7 T, which can be used as guidance in future studies quantifying metabolite and neurotransmitter concentrations with (1) H-MRS at ultra-high magnetic field.

    Full Text Available A research and development (R&D approach has been applied to video telephony (VT in northern Finland since 1994 by broad consortia. The focus has been on the considerable involvement of ergonomics within the engineering and implementation of VT. This multidisciplinary participatory ergonomic R&D approach (PERDA is described briefly, in general and through two cases. The user-centeredness should be discernible in this sociotechnical systemic entity. A consortium—comprising mainly manufacturers, individual and organizational users of technological products, and R&D organizations—serves as a natural context for product development. VT has been considered to have much potential for enhancing (multimedia interaction and effective multimodal communication, thereby facilitating many activities of everyday life and work. An assessment of the VT system, called HomeHelper, involved older citizens, as clients or customers, and the staff of social, health, and other services.

    User profile description is the core component of personalized search algorithm. The traditional keywords based vector space model is too simple to describe the user profile completely. By combining the structure of folksonomy and the explicit semantic of ontology concepts,a multi-layer user profile description model is proposed. Both user interesting and user relation are taken into considered in the model, and user profile can be described in different abstract layer such as tag,documents annotated and topics. Evaluation method of personalized search and the effect of resource type on user profile are also discussed. Experiments on Delicious dataset and Flickr dataset show that the user profile model proposed can improve personalized search performance effectively.%用户特征的描述方式是实现个性化搜索算法的核心因素.针对传统的基于关键词向量空间模型的用户特征描述过于简单,不能全面描述用户兴趣的缺陷,将folksonomy的结构与本体概念的清晰语义相结合,提出一种多层用户特征描述方式.从用户兴趣主题、用户间关联两个不同角度,从用户生成的标签、标记的文档及主题等不同层次建立用户特征描述模型,并将其应用于个性化搜索过程的方式进行分析.同时对个性化搜索的结果评价方式、资源类型对用户特征及搜索结果的影响进行了讨论.在Delicious和Flickr两种不同类型数据集上的实验表明,所提出用户特征模型能够有效提高个性化搜索结果的性能.

    2015-01-01

    Solar irradiance variations over solar rotational time-scales are largely determined by the passage of magnetic structures across the visible solar disk. Variations on solar cycle time scales are thought to be similarly due to changes in surface magnetism with activity. Understanding the contribution of magnetic structures to total solar irradiance and solar spectral irradiance requires assessing their contributions as a function of disk position. Since only relative photometry is possible from the ground, the contrasts of image pixels are measured with respect to a center-to-limb intensity profile. Using nine years of full-disk red and blue continuum images from the Precision Solar Photometric Telescope at the Mauna Loa Solar Observatory (PSPT/MLSO), we examine the sensitivity of continuum contrast measurements to the center-to-limb profile definition. Profiles which differ only by the amount of magnetic activity allowed in the pixels used to determine them yield oppositely signed solar cycle length continuu...

    2014-01-01

    Background Web-based programs have been developed for informal caregivers of people with Alzheimer’s disease (PWAD). However, these programs can prove difficult to adopt, especially for older people, who are less familiar with the Internet than other populations. Despite the fundamental role of usability testing in promoting caregivers’ correct use and adoption of these programs, to our knowledge, this is the first study describing this process before evaluating a program for caregivers of PWAD in a randomized clinical trial. Objective The objective of the study was to describe the development process of a fully automated Web-based program for caregivers of PWAD, aiming to reduce caregivers’ stress, and based on the user-centered design approach. Methods There were 49 participants (12 health care professionals, 6 caregivers, and 31 healthy older adults) that were involved in a double iterative design allowing for the adaptation of program content and for the enhancement of website usability. This process included three component parts: (1) project team workshops, (2) a proof of concept, and (3) two usability tests. The usability tests were based on a mixed methodology using behavioral analysis, semistructured interviews, and a usability questionnaire. Results The user-centered design approach provided valuable guidelines to adapt the content and design of the program, and to improve website usability. The professionals, caregivers (mainly spouses), and older adults considered that our project met the needs of isolated caregivers. Participants underlined that contact between caregivers would be desirable. During usability observations, the mistakes of users were also due to ergonomics issues from Internet browsers and computer interfaces. Moreover, negative self-stereotyping was evidenced, when comparing interviews and results of behavioral analysis.

    With 35 million web pages and 22,000 websites, the U.S. Federal Government through the E-Government Act 2002 directs those who develop and maintain these websites to become more "citizen-centered." One required activity of the act is to "sponsor ongoing dialogue with interested parties (including state, local, and tribal governments, private and non-profit sectors, and the general public) to find innovative ways to use IT to improve the delivery of Government information and services" (Sec 101, 3602). One of the websites that has begun to engage such parties is the NOAA Coral Reef Information System (CoRIS), which is designed to provide the public with access to NOAA's coral reef data and information from a single location. CoRIS has, through two usability workshops conducted by staff from the Coastal Services Center, and a series of stakeholder meetings held in the Fall of 2003 in American Samoa and Hawai'i and the Fall of 2004 in Puerto Rico and the U.S. Virgin Islands, sought to address the needs of users, both internal and external to NOAA. The goal was to select a set of test participants that represented the CoRIS project's targeted users (researchers, managers, general public) and provide an overview of the web site to demonstrate its resources and capabilities. The findings of the workshops and meetings are being used by the CoRIS development team to respond to user needs as part of an iterative process to improve utility and usability of the website and better understand how to present often complex scientific information to address a variety of user needs and local issues. Based on recommendations from the feedback of current and potential users of the CoRIS website from meetings held in the Fall of 2004, the development team has adopted a series of usability requirements to be implemented in the coming year. Participants of the meetings have suggested that CoRIS engage with user communities, including Local Action Strategy (LAS) efforts, to assess user

    This study is based on a survey designed to determine the Information Seeking Behavior (ISB) of Astronomy and Astrophysics users in India. The main objective of the study is to determine the sources consulted and the general pattern of the information-gathering system of users and the impact of Information and Communication Technology (ICT) on the Astronomy and Astrophysics user's Information Seeking Behavior. It examines various Information and Communication Technology-based resources and methods of access and use. A descriptive sample stratified method has been used and data was collected using a questionnaire as the main tool. The response rate was 72%. Descriptive statistics were also employed and data have been presented in tables and graphs. The study is supported by earlier studies. It shows that Astronomy and Astrophysics users have developed a unique Information Seeking Behavior to carry out their education and research. The vast majority of respondents reported that more information is available from a variety of e-resources. Consequently, they are able to devote more time to seek out relevant information in the current Information and Communication Technology scenario. The study also indicates that respondents use a variety of information resources including e-resources for teaching and research. Books and online databases such as the NASA Astrophysics Data System (ADS) were considered more important as formal sources of information. E-mail and face-to-face communications are used extensively by users as informal sources of information. It also reveals that despite the presence of electronic sources, Astronomy and Astrophysics users are still using printed materials. This study should to help to improve various Information and Communication Technology-based services. It also suggests that GOI should adopt Information and Communication Technology-based Information Centers and Libraries services and recommends a network-based model for Astronomy and

    Background Complex patients with multiple chronic conditions often face significant challenges communicating and coordinating with their primary care physicians. These challenges are exacerbated by the limited time allotted to primary care visits. Objective Our aim was to employ a user-centered design process to create a tablet tool for use by patients for visit discussion prioritization. Methods We employed user-centered design methods to create a tablet-based waiting room tool that enables complex patients to identify and set discussion topic priorities for their primary care visit. In an iterative design process, we completed one-on-one interviews with 40 patients and their 17 primary care providers, followed by three design sessions with a 12-patient group. We audiorecorded and transcribed all discussions and categorized major themes. In addition, we met with 15 key health communication, education, and technology leaders within our health system to further review the design and plan for broader implementation of the tool. In this paper, we present the significant changes made to the tablet tool at each phase of this design work. Results Patient feedback emphasized the need to make the tablet tool accessible for patients who lacked technical proficiency and to reduce the quantity and complexity of text presentation. Both patients and their providers identified specific content choices based on their personal experiences (eg, the ability to raise private or sensitive concerns) and recommended targeting new patients. Stakeholder groups provided essential input on the need to augment text with video and to create different versions of the videos to match sex and race/ethnicity of the actors with patients. Conclusions User-centered design in collaboration with patients, providers, and key health stakeholders led to marked evolution in the initial content, layout, and target audience for a tablet waiting room tool intended to assist complex patients with setting

    2012-08-01

    Natural movements and force feedback are important elements in using teleoperated equipment if complex and speedy manipulation tasks are to be accomplished in remote and/or hazardous environments, such as hot cells, glove boxes, decommissioning, explosives disarmament, and space to name a few. In order to achieve this end the research presented in this paper has developed an admittance type exoskeleton like multi-fingered haptic hand user interface that secures the user’s palm and provides 3-dimensional force feedback to the user’s fingertips. Atypical to conventional haptic hand user interfaces that limit themselves to integrating the human hand’s characteristics just into the system’s mechanical design this system also perpetuates that inspiration into the designed user interface’s controller. This is achieved by manifesting the property differences of manipulation and grasping activities as they pertain to the human hand into a nonlinear master-slave force relationship. The results presented in this paper show that the admittance-type system has sufficient bandwidth that it appears nearly transparent to the user when the user is in free motion and when the system is subjected to a manipulation task, increased performance is achieved using the nonlinear force relationship compared to the traditional linear scaling techniques implemented in the vast majority of systems.

    The Digital Accessible Information SYstem (DAISY) player is an assistive reading tool developed for use by persons with visual impairments. Certain problems have persisted in the operating procedure and interface of DAISY players, especially for their Chinese users. Therefore, the aim of this study was to redesign the DAISY player with increased usability features for use by native Chinese speakers. First, a User Centered Design (UCD) process was employed to analyze the development of the prototype. Next, operation procedures were reorganized according to GOMS (Goals, Operators, Methods, and Selection rules) methodology. Then the user interface was redesigned according to specific Universal Design (UD) principles. Following these revisions, an experiment involving four scenarios was conducted to compare the new prototype to other players, and it was tested by twelve visually impaired participants. Results indicate the prototype had the quickest operating times, the fewest number of operating errors, and the lowest mental workloads of all the compared players, significantly enhancing the prototype's usability. These findings have allowed us to generate suggestions for developing the next generation of DAISY players for people, especially for Chinese audience.

    Full Text Available Background: In the recent decades increasing number of women have been seeking deaddiction services. Despite that the report data is very limited from India. Objectives: The present research aimed to study the demographic and clinical profile of women seeking deaddiction treatment at a tertiary care center in North India. Materials and Methods: Retrospective structured chart review of 100 women substance abusers seeking treatment at a deaddiction center between September 1978 and December 2011. Results: A typical case was of 36.3 years age, married (65%, urban (61%, nuclear family (59% based housewife (56%, with good to fair social support (69%. The commonest substance of abuse was tobacco (60%, followed by opioids (27%, alcohol (15%, and benzodiazepines (13%. The common reasons for initiation of substance use were to alleviate frustration or stress (49% and curiosity (37%. Family history of drug dependence (43%, comorbidity (25%, and impairments in health (74%, family (57%, and social domains (56% were common. Only a third of the sample paid one or more follow visit, and of those 58% were abstinent at the last follow-up. Significant predictors identified were being non-Hindu and higher educational years for abstinent status at follow-up. Conclusion: The common substances of abuse were tobacco, opioids, and alcohol and benzodiazepines; and family history of drug abuse and comorbidity were common. The follow-up and outcome were generally poor. This profile gives us some clues to address a hidden health problem of the community.

    In this work, the applicability of mean centering (MC) of ratio kinetic profiles method to the kinetic voltammetry data is verified. For this purpose, a procedure is described for the determination of Sb(III) and Sb(V) by adsorptive linear sweep voltammetry using pyrogallol (py) as a complexing agent. The method is based on the differences between the rate of complexation of pyrogallol with Sb(V) and Sb(III) at pH 1.2. The results show that the mean centering of ratio kinetic profiles method is suitable for the speciation of antimony. Sb(III) and Sb(V) can be determined in the ranges of 3.0-120.0 and 10.0-240.0 ng mL(-1), respectively. Moreover, the solution is analyzed for any possible effects of foreign ions. The obtained results show that the method of MC in combination to electroanalytical techniques is a powerful method with high sensitivity and selectivity. The procedure is successfully applied to the speciation of antimony in pharmaceutical preparations.

    It has been recently proved that the computational analysis of X-ray Computed Tomography (CT) images allows clinicians to assess the alteration of compact bone asset due to hematological diseases. HT-BONE implements a new method, based on an extension of the Hough transform (HT) to a wide class of algebraic curves, for accurately measuring global and regional geometric properties of trabecular and compact bone districts. In the case of CT/PET analysis, the segmentation of the CT images provides masks for Positron Emission Tomography (PET) data, extracting the metabolic activity in the region surrounded by compact bone tissue. HT-BONE offers an intuitive, user-friendly, Matlab-based Graphical User Interface (GUI) for all input/output procedures and the automatic managing of the segmentation process also from non-expert users: the CT/PET data can be loaded and browsed easily and the only pre-preprocessing required from the user is the drawing of Regions Of Interest (ROIs) around the bone districts under consideration. For each bone district, specific families of curves, whose reliability has been already tested in previous works, is automatically selected for the recognition task via HT. As output, the software returns masks of the segmented compact bone regions, images of the Standard Uptake Values (SUV) in the masked regions of PET slices, and the values of the parameters in the curve equations utilized in the HT procedure. This information can be used for all pathologies and clinical conditions for which the alteration of the compact bone asset or bone marrow distribution plays a crucial role.

    Although various attempts have been made to build collaborative cultures for data sharing, their effectiveness is still questionable. The Jackson Heart Study (JHS) Vanguard Center (JHSVC) at the NIH-funded Research Centers in Minority Institutions (RCMI) Translational Research Network (RTRN) Data Coordinating Center (DCC) may be a new concept in that the data are being shared with a research network where a plethora of scientists/researchers are working together to achieve their common goal. This study describes the current practices to share the JHS data through the mechanism of JHSVC. The JHS is the largest single-site cohort study to prospectively investigate the determinants of cardiovascular disease among African-Americans. It has adopted a formal screened access method through a formalized JHSVC mechanism, in which only a qualified scientist(s) can access the data. The role of the DCC was to help RTRN researchers explore hypothesis-driven ideas to enhance the output and impact of JHS data through customized services, such as feasibility tests, data querying, manuscript proposal development and data analyses for publication. DCC has implemented these various programs to facilitate data utility. A total of 300 investigators attended workshops and/or received training booklets. DCC provided two online and five onsite workshops and developed/distributed more than 250 copies of the booklet to help potential data users understand the structure of and access to the data. Information on data use was also provided through the RTRN website. The DCC efforts led to the production of five active manuscript proposals, seven completed publications, 11 presentations and four NIH grant proposals. These outcomes resulted from activities during the first four years; over the last couple of years, there were few new requests.

    In 2009 the German BMBF (German Ministry of Education and Research) established an Integrated Center for Research and Treatment (IFB(LMU)) of Vertigo, Balance and Ocular Motor Disorders in Munich. After the 10-year period of funding by the BMBF, it is envisioned that the (IFB(LMU)) will continue over the long term with the joint support of the University Hospital, the Medical Faculty, and the Bavarian State. Vertigo is one of the most common complaints in medicine. Despite its high prevalence, patients with vertigo generally receive either inappropriate or inadequate treatment. This deplorable situation is internationally well known and its causes are multiple: insufficient interdisciplinary cooperation, no standardized diagnostics and therapy, the failure to translate findings of basic science into clinical applications, and the scarcity of clinical multicenter studies. The (IFB(LMU)) will constitute a suitable tool with which these structural, clinical, and scientific deficits can be overcome. It will also make possible the establishment of an international interdisciplinary referral center. Munich has become the site of a unique concentration of leading experts on vertigo, balance and ocular motor disorders, both in the clinical and basic sciences. Academic structures have paved the way for the creation of an interdisciplinary horizontal network that also allows structured, vertical academic career paths via the Bachelor's and Master's degree programs in Neuroscience, a Graduate School of Systemic Neurosciences, and the Munich Center for Neurosciences - Brain and Mind. The (IFB(LMU)) has the following objectives as regards structure and content: to create an independent patient-oriented clinical research center under the auspices of the Medical Faculty but with autonomous administration and budget; to overcome existing clinical and academic barriers separating the traditional specializations; to establish a standardized interdisciplinary longitudinal and

    Full Text Available The study was designed to determine clinical profile of haemophilia patients in North India. In this cross-sectional study, we obtained family history and clinical profile of 54 diagnosed severe haemophilia patients attending Haemophilia Treatment Centre, Children Hospital LLR Hospital, Kanpur, India, for factor replacement therapy. We also obtained blood samples to investigate for hepatitis B, HIV. In study we observed that majority of the patients having their first presentation in their infancy (70.3% and median age of first presentation was 11 months of age. Though haemophilia is a genetic disorder, family history was negative in majority of patients; (70.3% subcutaneous tissue was most frequent site for initial bleeds, but as age advances joints become frequently involved and hemarthrosis was commonest complication affecting 79.6% patients. Most common involved joint was knee joint (53.7%. This hemarthrosis is the major cause of morbidity affecting quality of life of patients. Due to cost of treatment, many times we have to transfuse blood and blood products which may lead to Transfusion Transmitted Infection (TTI. In our study prevalence of TTI was 1.85% and 3.70% for HIV and Hep. B respectively. We also observed that there was time lag of >1 month in 16.5% cases between onset of symptom and definitive diagnosis, which shows lack of awareness among doctors in community. In view of this high morbidity and TTIs, we emphasize the free availability of factor concentrates and prophylactic treatment should be followed instead of palliative treatment.

    Since achieving first light in December of 2005, the NASA Langley Research Center (LaRC) Airborne High Spectral Resolution Lidar (HSRL) has been involved in seven field campaigns, accumulating over 450 hours of science data across more than 120 flights. Data from the instrument have been used in a variety of studies including validation and comparison with the Cloud- Aerosol Lidar and Infrared Pathfinder Satellite Observation (CALIPSO) satellite mission, aerosol property retrievals combining passive and active instrument measurements, aerosol type identification, aerosol-cloud interactions, and cloud top and planetary boundary layer (PBL) height determinations. Measurements and lessons learned from the HSRL are leading towards next-generation HSRL instrument designs that will enable even further studies of aerosol intensive and extensive parameters and the effects of aerosols on the climate system. This paper will highlight several of the areas in which the NASA Airborne HSRL is making contributions to climate science.

    Full Text Available Introduction. Despite the advances in antibiotherapy and critical care management, infectious complications remain among the leading complications after liver transplantation related with mortality and morbidity. This study analysis the incidence and pattern of infections and possible prognostic factors of infectious compli- cations retrospectively in a single center. Patients and Methods. Results of 30 consecutive patients with a primary liver transplantation history in a single center between August 2011 and August 2012 and a positive culture result in the first month in the ICU were analysed retrospectively. Results. During the first 1 month stay in the ICU postoperatively 30 (13,63% patients had at least 1 infection. Total number of infections were 68. Mortality rate of the infected patients was 53,3% (n = 16. Among these infections, 25 (36,76% of them were in deep surgical sites. Eighteen of the 30 patients (60% were infected with a single microorganism. Eleven patients (36,66% had a single infection episode. Microorganism were gram negative in 52 (76,47% of the infections, gram positive in 14 (20,58% of the infections, rest of the 2 (2,94% infections were due to Candidiasis. Among the possible risk factors contributing to mortality, there was a statistically significant dif- ference (p < 0,001 between the platelet counts of the mortality and surviving groups of the patients. Conclu- sion. Infections are among the preventable risk factors for mortality and morbidity after liver transplantation. Our data reveals a significant relation between trombocytopenia and mortality among the infected patients. Further studies focusing on this relation would expose the mechanisms and any possible contribution in cli- nical management of the patients.

    Full Text Available BACKGROUND : Incidence of rectal cancer has wide geographical variation. Disease pattern in developing countries is different from developed countries as majority of the patients present in advanced stage because of delayed referral and lack of uniform treatment practices. AIMS : Present study describes the patient profile and treatment results from a tertiary care cancer center in India. SETTING AND DESIGN : Tertiary care Regional cancer center. Retrospective analysis 89 patients with rectal adenocarcinoma treated between 1995 and 2002 were analyzed. METHODS: Patients with adenocarcinoma rectum were evaluated in a G.I. Oncology clinic and were treated using multimodality protocols involving surgery, radiotherapy and adjuvant chemotherapy. STATISTICAL ANALYSIS : A descriptive analysis of patient and disease profile,treatment patterns and out come was performed. Survival analysis was performed using Kaplan-Meier method. RESULTS : Mean age of the patients was 45.4 years and majority of them had tumor in lower third of rectum with evidence of extrarectal spread. Seventy five percent of the patients underwent curative resection with abdominoperineal resection being the commonest procedure. Forty seven percent of patients were given short course preoperative radiotherapy and the remaining received postoperative radiotherapy. Sixty four percent of patients could complete planned adjuvant chemotherapy. Operative mortality was 2% and 23% had morbidity. Local recurrence rate was 8.9%. 5-year disease free and overall survival was 54% and 58% respectively. CONCLUSION : Majority of rectal cancer patients present with locally advanced and low rectal growths leading to low sphincter salvage rates. Despite the advanced stage of presentation optimal oncologic results can be obtained by using a good surgical techniques in combination with adjuvant radiotherapy and chemotherapy. Short course preoperative radiotherapy seems to be more feasible in Indian context

    The factors and demographic features of self-inflicted burns in Eastern and Western cultures differ from each other. In this retrospective study, the authors' aim is to identify the epidemiologic features of self-inflicted burn patients treated at their Tertiary Burn Centre. The Burn Centre provides health care to a large population from Istanbul, which is located at the crossroads between Asia and Europe. The demographic data and information of 32 patients who were admitted to the GATA HEH Burn Center in Istanbul for attempted suicide were retrospectively reviewed over a 7-year period (2001-2008). Twenty-eight of the 32 patients were men, whereas the remaining four patients were women. The average age was 25.9 years. Seventeen patients had a previous history of self-harming and 22 patients were unemployed. History of a psychiatric illness was found in 20 patients. Mean total body burn surface area was 70%. The mortality rate was 43.4%. This study demonstrates that suicide attempts by burning differ from Eastern and Western cultures by factors and demographic features. It has been concluded that the solution to preventing self-inflicted burns calls for the joint efforts of physicians, psychologists, and sociologists. Furthermore, it is necessary to reinstate prevention programs and revise strategies for prevention based on the country and its culture.

    The Estonian Biobank cohort is a volunteer-based sample of the Estonian resident adult population (aged ≥18 years). The current number of participants-close to 52000--represents a large proportion, 5%, of the Estonian adult population, making it ideally suited to population-based studies. General practitioners (GPs) and medical personnel in the special recruitment offices have recruited participants throughout the country. At baseline, the GPs performed a standardized health examination of the participants, who also donated blood samples for DNA, white blood cells and plasma tests and filled out a 16-module questionnaire on health-related topics such as lifestyle, diet and clinical diagnoses described in WHO ICD-10. A significant part of the cohort has whole genome sequencing (100), genome-wide single nucleotide polymorphism (SNP) array data (20 000) and/or NMR metabolome data (11 000) available (http://www.geenivaramu.ee/for-scientists/data-release/). The data are continuously updated through periodical linking to national electronic databases and registries. A part of the cohort has been re-contacted for follow-up purposes and resampling, and targeted invitations are possible for specific purposes, for example people with a specific diagnosis. The Estonian Genome Center of the University of Tartu is actively collaborating with many universities, research institutes and consortia and encourages fellow scientists worldwide to co-initiate new academic or industrial joint projects with us.

    The refractory research group at the Albany Research Center (ARC) has a long history of conducting materials research within the U.S. Bureau of Mines, and more recently, within the U.S. Dept. of Energy. When under the U.S. Bureau of Mines, research was driven by national needs to develop substitute materials and to conserve raw materials. This mission was accomplished by improving refractory material properties and/or by recycling refractories using critical and strategic materials. Currently, as a U.S. Dept of Energy Fossil Energy field site, research is driven primarily by the need to assist DOE in meeting its vision to develop economically and environmentally viable technologies for the production of electricity from fossil fuels. Research at ARC impacts this vision by: • Providing information on the performance characteristics of materials being specified for the current generation of power systems; • Developing cost-effective, high performance materials for inclusion in the next generation of fossil power systems; and • Solving environmental emission and waste problems related to fossil energy systems. A brief history of past refractory research within the U.S. Bureau of Mines, the current refractory research at ARC, and the equipment and capabilities used to conduct refractory research at ARC will be discussed.

    Full Text Available The early declaration of Quito as a World Heritage site in 1978, makes this city a Latin American example with a remarkable preservationist experience. Its Historical Centre composes a blend of periods and goods, emphasizing on the presence of Spanish-Aborigine syncretism stands. This hybridation survives in the buffer area, made up of different neighborhoods, through a residential property typology: the patio houses. With endless complexities to their approach, these homes comprise the residential identity of Quito, but they have only recently taken on a new protagonism within a residential protection framework. Therefore, and through a historical-architectural and social approach, has been investigated the patrimonial fragment of the neighbourhood of San Juan, which is representative of what happens in the buffer area. Diagnosisand guidelines are exposed from a conception of exploratory study, mainly qualitative and focused on users awareness. This approximation has been carried on through the observation in situ, the analysis of planimetry, bibliography, photographs, the carrying out of interviews and opinion polls. Thus, final reflections are presented along with a methodological development feasible of being adapted to other residential properties in other urban contexts. La temprana declaración de Quito como Patrimonio de la Humanidad en 1978 la convierte en un ejemplo latinoamericano con una singular experiencia preservacionista. Su Centro Histórico compone una amalgama de períodos y bienes, destacándose la presencia del sincretismo español-aborigen. Esta hibridación sobrevive en el área de amortiguación, compuesta por diferentes barrios, a través de una tipología residencial característica: las casas patio. Con un sinfín de complejidades para su tratamiento, estas viviendas componen gran parte de la identidad habitacional quiteña, aunque sólo recientemente han adquirido un nuevo protagonismo dentro del marco de protecci

    Background: There is little published literature on the profile of patients with Cushing's syndrome (CS) from India. The aim of this study was to compile data of CS patients treated at this hospital. Materials and Methods: Patients referred to the endocrine services of this hospital for diagnosis/treatment of CS from January 1985 to July 2012 were the subjects for this study. All patients had detailed medical history, physical examination and biochemical and hormonal assays (which changed with availability of tests and changing views). Assays for plasma adrenocorticotropic hormone (ACTH) (late 90s), salivary cortisol estimation, IJV sampling for ACTH and corticotrophin releasing hormone stimulation tests were added on later. Imaging included computed tomography (CT), magnetic resonance imaging (since the late 80's) and 68Ga DOTA-TOC/FDG PET-CT (2008). Results: Three hundred sixty-four patients (250 females, 114 males, age 6 months to 65 years, mean 28 years + 12 years) were diagnosed to have CS during this period. Two hundred and ninety-three patients (80.5%) were ACTH dependent (CD 215, ectopic ACTH syndrome 22, occult ACTH source 56) while 71 (19.5%) were ACTH independent (adrenal carcinoma 36, adenoma 30, primary pigmented nodular adrenal disease 4, AIMAH 1). Pituitary macro adenoma was seen in 14% of the CD cases. The most common presenting complaints were hypertension and diabetes mellitus. A total of 63% patients complained of weight gain while 15% had lost weight. Myopathy, infections, skeletal fractures and psychiatric problems were the other common observations in our patients. Conclusion: The clinical spectrum was broad. CD was the most common cause for CS. PMID:24701438

    User frustrations are an excellent source of new product ideas. Starting with this observation, this article describes an approach that entrepreneurs can use to discover business opportunities. Opportunity discovery starts with a problem that the user has, but may not be able to articulate. User-centered design techniques can help elicit those latent needs. The entrepreneur should then try to understand how users are solving their problem today, before proposing a solution that draws on the u...

    Full Text Available OBJECTIVE: To evaluate clinical profiles, predictors of 30-day mortality, and the adherence to international recommendations for the treatment of myocardial infarction in an academic medical center hospital. METHODS: We retrospectively studied 172 patients with acute myocardial infarction, admitted in the intensive care unit from January 1992 to December 1997. RESULTS: Most patients were male (68%, white (97%, and over 60 years old (59%. The main risk factor for coronary atherosclerotic disease was systemic blood hypertension (63%. Among all the variables studied, reperfusion therapy, smoking, hypertension, cardiogenic shock, and age were the predictors of 30-day mortality. Most commonly used medications were: acetylsalicylic acid (71%, nitrates (61%, diuretics (51%, angiotensin-converting enzyme inhibitors (46%, thrombolytic therapy (39%, and beta-blockers (35%. CONCLUSION: The absence of reperfusion therapy, smoking status, hypertension, cardiogenic shock, and advanced age are predictors of 30-day mortality in patients with acute myocardial infarction. In addition, some medications that are undoubtedly beneficial have been under-used after acute myocardial infarction.

    Full Text Available Context: A shift towards person-centered care has been occurring in services provided to people with mood and anxiety disorders. Recovery is recognized as encompassing personal aspects in addition to clinical ones. Guidelines now recommend supporting people’s engagement in self-management as a complementary recovery avenue. Yet the literature lacks evidence on how individualized combinations of self-management strategies used by people relate to their clinical and personal recovery indicators. Objectives: The aim of this study was to identify profiles underlying mental health recovery, describe the characteristics of participants corresponding to each profile, and examine the associations of profiles with criterion variables. Method: 149 people recovering from anxiety, depressive, or bipolar disorders completed questionnaires on self-management, clinical recovery (symptom severity, personal recovery (positive mental health, and criterion variables (personal goal appraisal, social participation, self-care abilities, coping. Results: Latent profile analysis revealed three profiles. The Floundering profile included participants who rarely used self-management strategies and had moderately severe symptoms and the lowest positive mental health. The Flourishing profile was characterized by frequent use of self-empowerment strategies, the least severe symptoms, and the highest positive mental health. Participants in the Struggling profile engaged actively in several self-management strategies focused on symptom reduction and healthy lifestyle. They concomitantly reported high symptom severity and moderately high positive mental health. The study revealed that Floundering was associated with higher probabilities of being a man, being single, and having a low income. People in the Flourishing profile had the most favorable scores on criterion variables, supporting the profiles’ construct validity. Discussion: The mixed portrait of Struggling

    Full Text Available Background: Hepatitis B virus (HBV, hepatitis C virus (HCV, and human immunodeficiency virus (HIV are the three prevalent viral and bloodborne infections worldwide. Considering the similar route of transmission in these infections, their co-infections would be more challenging for health care professionals. Therefore, we investigated the rate of HIV/HBV/HCV co-infection among injection drug users (IDUs referred to Drop in centers (DICs. Materials and Methods: In this cross-sectional study (2008-2009, IDUs referred to DICs in Isfahan province were evaluated. Venous blood samples were obtained and HBsAg, HBcAb, HCVAb, and HIVAb measured by using enzyme linked immunosorbent assay method. Demographic data and risk factors in patients with HBV/HCV, HIV/HCV, and HIV/HBV co-infections were obtained by a trained social worker using a structured checklist. Data were analyzed using Chi-square test, t-test, and multiple logistic regressions. Results: Totally, 539 IDUs with mean (standard deviation [SD] age of 35.3 (7.9 were studied. HBV/HCV, HCV/HIV, and HBV/HIV co-infections were presented in 65 (12.1%, 6 (1.1%, and 0 (0% of IDUs, respectively. All HIV infected IDUs were infected with HCV as well. There was a significant association between HBV/HCV co-infection and behaviors related to sharing needle (odds ratio [OR] = 2.06, 95% confidence interval [CI]; 1.23-3.45 and imprisonment (OR = 1.01, 95% CI; 1.04-1.06. Conclusion: According to the results of this study, history of imprisonment and needle sharing were the only adjusted risk factors for HCV/HBV co-infection in IDUs. This might be a warning for national health system and needs to urgent paying attention. It seems that expanded harm reduction strategies can be useful to reduce this co-infection and its mortality and morbidity rate among IDUs.

    Full Text Available Objective: Comprehensive statistics on gynecologic malignancies reported from India are deficient. This study was performed to ascertain the profile of gynecologic cancers reported at our center regarding incidence, histologic subtypes, frequency of involvement at various sites and stage at presentation. We endeavored to compare our data with gynecologic cancers reported at other national and international centers. Materials and Methods: Retrospective review of records of gynecologic cancers obtained from Departments of Pathology and Gynecology, at a tertiary care center, Delhi from January 2000 to December 2009 was performed. Comparison with international data was performed using Fishcher′s exact test and chi square tests. Results: A total of 1315 gynecologic cancers were reported. Cervical malignancies were the commonest at our center as compared to uterine malignancies in data from Surveillance, Epidemiology, and End Results (SEER Program of United States and European Union. All malignancies except cervical cancers affected a younger age group at our center than in the US population. Cervical cancer presented at a relatively more advanced stage, ovarian cancers at more localized stages, whereas uterine cancers presented at similar stages as compared to Western data. Conclusions: Our registry presents composite data from North India. Higher age and advanced stage at presentation of cervical cancers suggests lacunae in screening programs available. Ovarian malignancies were more localized at presentation than in the Western population for which environmental or genetic factors may be causative.

  20. User Registration in EOSDIS

    Science.gov (United States)

    Murphy, K. J.; Mitchell, A. E.

    2009-12-01

    Throughout the lifetime of EOSDIS the topic of user registration has received varied attention. Initially, for example, users ordering data from the Earth Science Data Gateway were required to register for delivery of media orders, to check order status and save profile information for future interactions. As EOSDIS embraced evolution of its data systems, the mostly centralized search and order system was replaced with a more diverse set of interfaces allowing (mostly) anonymous online access to data, tools and services. The changes to EOSDIS were embraced by users but the anonymous nature of the interaction made it more difficult to characterize users, capture metrics and provide customized services that benefit users. Additionally, new tools and interfaces have been developed without a centralized registration system. Currently a patchwork of independent registration systems exists throughout EOSDIS for ordering data and interacting with online tools and services. Each requires a separate username and password that must be managed by users. A consolidation of registration systems presents an opportunity to improve not only the user experience through tool customization and simplification of password management, but the understanding of users. This work discusses the options for implementing a common user registration for the EOSDIS, anticipated benefits and pitfalls.

Opportunity discovery starts with a problem that the user has, but may not be able to articulate. User-centered design techniques can help elicit those latent needs. The entrepreneur should then try to understand how users are solving their problem today, before proposing a solution that draws on the unique skills and technical capabilities available to the entrepreneur. Finally, an in-depth understanding of the user allows the entrepreneur to hone in on the points of difference and resonance that are the foundation of a strong customer value proposition.

    Full Text Available Brain Computer Interfaces (BCI based on event-related potentials (ERP allow for selection of characters from a visually presented character-matrix and thus provide a communication channel for users with neurodegenerative disease. Although they have been topic of research for more than 20 years and were multiply proven to be a reliable communication method, BCIs are almost exclusively used in experimental settings, handled by qualified experts. This study investigates if ERP-BCIs can be handled independently by laymen without expert interference, which is inevitable for establishing BCIs in end-user’s daily life situations. Furthermore we compared the classic character-by-character text entry against a predictive text entry (PTE that directly incorporates predictive text into the character matrix. N=19 BCI novices handled a user-centred ERP-BCI application on their own without expert interference. The software individually adjusted classifier weights and control parameters in the background, invisible to the user (auto-calibration. All participants were able to operate the software on their own and to twice correctly spell a sentence with the auto-calibrated classifier (once with PTE, once without. Our PTE increased spelling speed and importantly did not reduce accuracy. In sum, this study demonstrates feasibility of auto-calibrating ERP-BCI use, independently by laymen and the strong benefit of integrating predictive text directly into the character-matrix.

    Full Text Available Background: Treatment-seeking is limited in women substance abusers. Studying the sociodemographic and clinical profile of treatment-seeking substance-dependent women can help us to understand the problem better and respond appropriately in terms of primary and secondary prevention strategies. Aim: To study the sociodemographic and clinical profile of women attending a de-addiction centre in North India. Design and Methodology: Retrospective structured chart review of 35 women substance abusers. Results: The results indicated that a typical subject was urban (86%, married (63%, nuclear family (60%, based housewife (57%, educated up to school completion (54%, and having poor social support (57%. The common substances were opioids (60%, followed by alcohol (17%, and tobacco and benzodiazepines (11.5% each. The mean age at onset of substance use was 30.5 years, the mean duration of use was 9 years and mean duration to develop dependence was 5.5 years. The common reasons for initiating use were medical (63% and curiosity (34%. Comorbidity profile was: physical illness (34%, psychiatric illness (23% and dependence on another substance (14%. Only 20% had a family history of substance dependence. The social impairment ranged from 77% for social to 40% for financial and none for legal aspects. A typical subject had followed up 4.2 times in 8.4 months, while 54% were abstaining, 40% were continuing their substance dependence at the last follow up. Conclusions: The results suggest that the development of substance dependence in women is a combination of genetic, personal, and social vulnerability factors, including the drug culture of the social milieu and the poor social support. Comorbidity and impairment are common features.

  15. THREE-DIMENSIONAL STELLAR KINEMATICS AT THE GALACTIC CENTER: MEASURING THE NUCLEAR STAR CLUSTER SPATIAL DENSITY PROFILE, BLACK HOLE MASS, AND DISTANCE

    International Nuclear Information System (INIS)

    We present three-dimensional (3D) kinematic observations of stars within the central 0.5 pc of the Milky Way (MW) nuclear star cluster (NSC) using adaptive optics imaging and spectroscopy from the Keck telescopes. Recent observations have shown that the cluster has a shallower surface density profile than expected for a dynamically relaxed cusp, leading to important implications for its formation and evolution. However, the true 3D profile of the cluster is unknown due to the difficulty in de-projecting the stellar number counts. Here, we use spherical Jeans modeling of individual proper motions and radial velocities to constrain, for the first time, the de-projected spatial density profile, cluster velocity anisotropy, black hole mass (M BH), and distance to the Galactic center (R 0) simultaneously. We find that the inner stellar density profile of the late-type stars, ρ(r)∝r –γ, have a power law slope γ=0.05−0.60+0.29, much more shallow than the frequently assumed Bahcall-Wolf slope of γ = 7/4. The measured slope will significantly affect dynamical predictions involving the cluster, such as the dynamical friction time scale. The cluster core must be larger than 0.5 pc, which disfavors some scenarios for its origin. Our measurement of MBH=5.76−1.26+1.76×106 M ☉ and R0=8.92−0.55+0.58 kpc is consistent with that derived from stellar orbits within 1'' of Sgr A*. When combined with the orbit of S0-2, the uncertainty on R 0 is reduced by 30% (8.46−0.38+0.42 kpc). We suggest that the MW NSC can be used in the future in combination with stellar orbits to significantly improve constraints on R 0

    User Design offers a fresh perspective on how front-line learners (users) can participate in the design of learning environments. The author challenges the universal assumption that front-line users must be relegated to the role of offering input, and that the actual design activity of learning systems must still be conducted only by experts. The book presents a new set of methods and strategies that show how the tools of professional designers can be effectively shared with broad groups of users and other participants in the process of creating their own learning. Drawing

    Ribosome profiling is a technique that permits genome-wide, quantitative analysis of translation and has found broad application in recent years. Here we describe a modified profiling protocol and software package designed to benefit more broadly the translation community in terms of simplicity and utility. The protocol, applicable to diverse organisms, including organelles, is based largely on previously published profiling methodologies, but uses duplex-specific nuclease (DSN) as a convenient, species-independent way to reduce rRNA contamination. We show that DSN-based depletion compares favorably with other commonly used rRNA depletion strategies and introduces little bias. The profiling protocol typically produces high levels of triplet periodicity, facilitating the detection of coding sequences, including upstream, downstream, and overlapping open reading frames (ORFs) and an alternative ribosome conformation evident during termination of protein synthesis. In addition, we provide a software package that presents a set of methods for parsing ribosomal profiling data from multiple samples, aligning reads to coding sequences, inferring alternative ORFs, and plotting average and transcript-specific aspects of the data. Methods are also provided for extracting the data in a form suitable for differential analysis of translation and translational efficiency. PMID:26286745

    The epidemiologic profile of infective endocarditis has changed substantially over the past few years, especially in industrialized countries. Our study evaluates the clinical and pathologic characteristics of infective endocarditis patients treated by cardiac surgery in China during a 12-year period. We retrospectively evaluated 220 surgically treated infective endocarditis patients and analyzed their changes from the beginning of 1998 through 2009. The mean age of the patients increased from 36.9 to 42.7 years during those 12 years (P=0.036). The chief predisposing disease was congenital heart disease (32.8%), rather than rheumatic heart disease (13.2%); this rate did not change significantly during the 12 years. The prevalent congenital lesion was bicuspid aortic valve, the rate of which (55.6%) increased significantly over the 3 time intervals studied (P=0.016). The frequency of infective endocarditis after non-dental surgical and nonsurgical intervention was significantly greater (23.3%) during 1998 through 2001, compared with the 2 intervals that followed (9%; P=0.019). Streptococcus viridans was the most frequent causative agent overall (25.6%). Forty-seven of the 220 patients (21.4%) carried the clinical diagnosis of some other form of heart disease before surgery, but at surgery they were found to have infective endocarditis as the fundamental disease process. Of 47 patients, 33 (70.2%) had either very small or no vegetations but had focal necrosis and inflammation of valve tissue that supported the diagnosis of infective endocarditis.

    Full Text Available Aim: To describe the clinical profile, maternal and fetal outcomes, and the conversion rates to diabetes in women with gestational diabetes mellitus (GDM seen at a tertiary care diabetes center in urban south India. Materials and Methods: Clinical case records of 898 women with GDM seen between 1991 and 2011 were extracted from the Diabetes Electronic Medical Records (DEMR of a tertiary care diabetes center in Chennai, south India and their clinical profile was analyzed. Follow-up data of 174 GDM women was available. To determine the conversion rates to diabetes, oral glucose tolerance test (OGTT was done in these women. Glucose tolerance status postpartum was classified based on World Health Organization (WHO 2006 criteria. Results: The mean maternal age of the women was 29 ± 4 years and mean age of gestation at first visit were 24 ± 8.4 weeks. Seventy percent of the women had a family history of diabetes. Seventy-eight percent of the women delivered full-term babies and 65% underwent a cesarean section. The average weight gain during pregnancy was 10.0 ± 4.2 kg. Macrosomia was present in 17.9% of the babies, hypoglycemia in 10.4%, congenital anomalies in 4.3%, and the neonatal mortality rate was 1.9%. Mean follow-up duration of the 174 women of whom outcome data was available was 4.5 years. Out of the 174, 101 women who were followed-up developed diabetes, of whom half developed diabetes within 5 years and over 90%, within 10 years of the delivery. Conclusions: Progression to type 2 diabetes mellitus (T2DM in Indian women with GDM is rapid. There is an urgent need to develop standardized protocols for GDM care in India that can improve the maternal and fetal outcomes and help prevent future diabetes in women with GDM.

    Full Text Available Background: Growth hormone deficiency (GHD in adults is associated with a cluster of cardiovascular risk factors that may contribute to an increased mortality for cardiovascular disease. In children, relatively few studies have investigated the effect of GHD and replacement therapy on cardiac performance and metabolic abnormalities that may place them at a higher risk of cardiovascular disease (CVD at an early age. Aim: This study was aimed to assess the left ventricular function, lipid profile, and degree of insulin resistance in Egyptian children with GHD before and after 1 year of GH replacement therapy. Settings and Design: Prospective case-control study, single-center study. Materials and Methods: Thirty children with short stature due to GHD were studied in comparison to 20 healthy age- and sex-matched children. All subjects were subjected to history, clinical examination, auxological assessment, and echocardiography to assess the left ventricular function. Blood samples were collected for measuring IGF-1, lipid profile (Total, LDL, HDL cholesterol, triglyceride, and atherogenic index (AI, fasting blood sugar, and fasting insulin levels. In addition, basal and stimulated GH levels were measured in children with suspected GHD. Statistical Analysis Used: Student′s t-test was used for parametric data, and the Mann-Whitney U-test was used for non-parametric data. Results: Total, LDL cholesterol, triglyceride, AI, and insulin were significantly higher in children with GHD than in healthy controls at baseline. After 12 months of GH replacement therapy, total, LDL cholesterol, triglyceride, AI and insulin were significantly decreased, while homeostatic model assessment for insulin resistance index (HOMA-IR was significantly increased compared to both pre-treatment and control values. At baseline, the left ventricular mass (LVM and left ventricular mass index (LVMi were significantly lower in GHD children than in controls. After 12 months of GH

    Full Text Available Introduction: Chediak-Higashi syndrome (CHS is a rare autosomal recessive disorder characterized by partial ocular and cutaneous albinism, increased susceptibility to pyogenic infections, the presence of large lysosomal-like organelles in most granule-containing cells and a bleeding tendency. The abnormal granules are most readily seen in blood and marrow leukocytes, especially granulocytes; and in melanocytes. Other clinical features include silvery hair, photophobia, horizontal and rotatory nystagmus and hepatosplenomegaly. Materials and Methods: The clinico-hematological profile of a series of 5 cases of CHS encountered at JIPMER Hospital with diagnostic work-up done in the Department of Pathology over the last 6 years is presented. The diagnostic work-up included complete hemogram with peripheral smear, bone marrow examination, skin and liver biopsies. Results: The age of the patients ranged from 5 months to 3 years. All patients had silvery hair and partial albinism and presented with fever and recurrent chest infection. Two patients were stable. Three patients were in accelerated phase; of them, 1 patient with associated hemophagocytic syndrome had a rapidly fulminant course. Peripheral blood smear showed anomalously large granules in the leukocytes. Skin biopsy showed sparse, coarse melanin pigment in the epidermis, and liver biopsy done in 2 patients with accelerated phase showed portal lymphohistiocytic aggregates. Conclusions: The diagnostic hallmark of CHS is the occurrence of giant inclusion bodies (granules in the peripheral leukocyte and their bone marrow precursors. The case series is being presented because of the rarity of CHS and varied spectrum of clinical and hematological presentation.

    Full Text Available Background: Hashimoto encephalopathy (HE is a poorly understood and often misdiagnosed entity with variable clinical spectrum. There are many uncertainties that still remain about this condition and the pathological significance of thyroid peroxidase (TPO antibody. Objective: To characterize the clinical, laboratory and radiologic findings in patients with HE. Design: Retrospective analysis of clinical features and diagnostic test data. Main Outcome Measures: Clinical features, laboratory, radiologic, electroencephalography (EEG findings associated with HE and therapeutic outcome. Results: Thirteen consecutive patients were identified as having HE. The median age at onset was 48.5 years (range, 19-62 years. There was a female preponderance (76.9%. Clinical manifestations were cognitive impairment and behavioral changes in 10 (76.9%, sleep disturbance in 9 (69.2%, seizures in 6 (46.1%, headache in 4 (30.8%, psychosis or paranoia in 5 (38.5%, transient symptoms in 6 (46.1%, myoclonus in 4 (30.8%, ataxia or gait disorder in 4 (30.8%. The most frequent laboratory abnormalities were increased TPO (n = 13 in all cases, increased thyroid stimulating hormone levels (n = 6, and increased erythrocyte sedimentation rate (n = 5. The cerebrospinal fluid protein level was elevated in 8 of 9 patients (88.8%. Magnetic resonance imaging abnormalities were present in 2 patients (15.4%. EEG changes were seen in 7 patients (53.8%. All but two patients showed significant therapeutic benefit with steroids. Conclusions: HE has a wide range of clinical, laboratory, and radiologic findings. All patients with an unexplained encephalopathy should be screened for this condition as treatment response is excellent. To the best of our knowledge, this is the largest single center clinical series of HE from the Indian subcontinent.

    1997-01-01

    The design of a functional interface for direct entry of physical exam data by physicians remains a formidable challenge for developers of clinical information systems. Many developers use a theoretical approach, basing the interface on a model of the structure of the information and of the user-system interaction that is developed with one or more clinical domain expert(s). We explored the use of empirical analysis as a basis for the design of a structured data entry (SDE) interface. A collection of physical examination data from actual trauma patients, dictated by trauma surgeons, was used for the analysis. Using simple parsers written in Visual BASIC, we used word frequency analysis (WFA) and manual editing to identify the frequencies of unique terms used by physicians in recording 688 HEENT and 712 LUNG physical exams. A second-pass WFA was used to determine associated descriptive terms. A simple SDE interface was created based on the results of these analyses. The interface was then evaluated by assessing the extent to which the HEENT and LUNG segments of similar physical exams could be fully recorded using the empirically-based SDE interface. Using this interface, 68% of 200 trial HEENT exams, and 85% of 200 trial LUNG exams could be fully recorded. The interface was also considered helpful in recording substantial portions of the remainder of the exams. We believe that WFA can be a useful tool for finding empirical basis for SDE design.

    Full Text Available Aim: Chronic iron overload resulting from frequent transfusions, poor compliance to efficient chelation therapy and chronic liver disease is basically responsible for the most severe complications of thalassemia major (TM. Before conventional treatment, TM was entirely childhood disease with a very short survival. Today, survival improved to 40–50 years and becomes a prevalent disease of adulthood and in the near future it will be one of senility. Furthermore, clinical phenotype of TM is changing with age and appearance of severe complications from the heart and endocrine glands that require special health care from well-informed specialists. Objectives: The aims of our study were to: (1 Imprint the clinical profile of long-lived TM patients; (2 evaluate retrospectively the cumulative incidence of endocrine diseases; (3 identify potential risk factors; and (4 orient the physicians in the modified clinical phenotype and the relative patients' health needs. Design: A retrospective cross-sectional study followed from childhood to adulthood by the same physician in a tertiary thalassemia clinic. Participants: Forty-three long-lived TM patients (mean age: 50.3 ± 10.8 years; range: 45.8–59.5 years; 23 females were studied. Patients and Methods: An extensive medical history, with detailed clinical and laboratory data, endocrine complications, and current treatments, was obtained. Results: The data indicate that 88.4% of adult TM patients suffered from at least one endocrine complication. The majority of patients developed endocrine complications in the second decade of life when serum ferritin level was very high (12/23 TM female and 8/20 TM male patients, the serum ferritin levels at the diagnosis were above 5.000 ng/ml. Conclusions: These data underline that endocrine and bone complications in adult TM patients are highly prevalent and necessitate close monitoring, treatment, and follow-up.

    Full Text Available Background: In India most of the tobacco cessation centers are concentrating only on urban population, whereas, literature reveals that it is rural population, which shows high frequency of consumption of tobacco. It is well known that high frequency of tobacco consumption is associated with psychological dependence. This study aimed at identifying, which form of tobacco consumption (smoking or smokeless is associated with psychological dependence and is associated with which particular age group in rural population. Materials and Methods: It was a questionnaire based survey where 200 subjects were enrolled. Revised version of standard Fagerstrom Test for Nicotine dependence (FTND was given to each subject to answer. The collected data was statistically analyzed by using Karl Pearson Correlation (r test and Student′s t-test. Results: Study showed that subjects above 40 years of age are psychologically highly dependent on tobacco smoking as compared to tobacco chewing. Tobacco chewing is more prevalent among the younger population (20-30 years of age and type of habit does not have any influence over psychological dependence below 40 years of age. A positive correlation was observed between duration of habit and psychological dependence in all age groups irrespective of type of the habit of tobacco consumption. Conclusion: This study attempts at creating a new avenue for the tobacco cessation centers where they can target their efforts towards rural population particularly people above 40 years of age with a tobacco smoking habit so that they can actually reduce the burden of a number of people at risk for developing tobacco associated oral cancer.

    2011-01-01

    Full Text Available Abstract The Open Profiling of Quality (OPQ is a mixed methods approach combining a conventional quantitative psychoperceptual evaluation and qualitative descriptive quality evaluation based on naïve participants' individual vocabulary. The method targets evaluation of heterogeneous and multimodal stimulus material. The current OPQ data collection procedure provides a rich pool of data, but full benefit of it has neither been taken in the analysis to build up completeness in understanding the phenomenon under the study nor has the procedure in the analysis been probed with alternative methods. The goal of this paper is to extend the original OPQ method with advanced research methods that have become popular in related research and the component model to be able to generalize individual attributes into a terminology of Quality of Experience. We conduct an extensive subjective quality evaluation study for 3D video on mobile device with heterogeneous stimuli. We vary factors on content, media (coding, concealments, and slice modes, and transmission levels (channel loss rate. The results showed that advanced procedures in the analysis cannot only complement each other but also draw deeper understanding on Quality of Experience.

    Algorithms for radiation protection services and regulators were developed. They provide guidelines for choosing actions in planning the elimination of accidents. Method is based on work with a grid of radiation field, which is obtained by interpolation of the measured values. Based on these algorithms, was developed a software with a graphical representation of the original data and the results of calculations. It allows us to evaluate the quality of information received from the monitoring team, search for the best routes on site and find points that make a maximum contribution to the collective dose. Regulator should control about 250 parameters of the radiation situation. Basically, this is a list of control points and the reference values of dose rate at these points for the technical area, buildings and structures located at the industrial site. For each point are two control values - the dose rate at rest and during work. It is more important for regulator to compare the radiation situation with control levels, but not only to see radiation situation itself. Our software graphically present information as areas on the map. Regulator with a glance at the screen can see where levels have been exceeded. It has shown that an important condition for the software implementation is that when facility use it, the operator's efficiency increases, while working time stay constant or reduces. This statement applies for input data into the database, mathematical analysis and present the results in a report drawn up in accordance with the rules of the company.

    Full Text Available OBJECTIVE: To evaluate the prevalence and the risk factors for tuberculosis (TB infection and disease among hospitalized cocaine users. METHOD: A cross-sectional study performed on a sample of 440 addicts over 18 years of age, admitted to hospitals of the metropolitan area of the Greater São Paulo city, whose clinical conditions allowed them to answer a standard questionnaire, and who agreed to participate in the study. The prevalence of TB infection was assessed through positive tuberculin testing (PPD, and of TB disease by the finding of M. tuberculosis in the sputum of patients with respiratory symptoms. RESULTS: Respiratory symptoms were present in 21% of the patients, the most frequent being weight loss and cough, which disappeared when cocaine use was discontinued. The general prevalence of TB infection was 28%. The prevalence of TB disease was 0.6%. The factors which were associated with positive PPD were: age, color/race, time spent in prison, and drug use in prison. CONCLUSION: No increased prevalence of TB infection and disease was found in these patients. Older addicts had a higher probability of having TB infection, and so had those who had been in prison.

  2. 'There is no profile it is just everyone': the challenge of targeting hepatitis C education and prevention messages to the diversity of current and future injecting drug users.

    Ellard, Jeanne

    2007-05-01

    This paper investigates drug use, knowledge of hepatitis C, and risk minimisation amongst participants of the Sydney inner city dance party/club scene. The aim is to identify factors that contribute to the limited success of hepatitis C education and prevention efforts in Australia and to suggest ways in which they might be improved. The method used was a thematic analysis of 31 semi-structured qualitative interviews with people drawn from the Sydney inner city dance party/club scene. This is a scene where the consumption of recreational drugs is normalised, and where the practice of injecting takes place, albeit less commonly to other routes of administration. In the material presented here, drugs are seen as sources of enjoyment and experimentation, but are not seen as necessary to the functioning of daily life. Indeed, dependency on drugs is largely seen as undesirable. Most participants consider themselves to be both well informed about the drugs they use, and in control of their drug use. Whilst participants in this scene are generally well informed about drugs (and deploy harm reduction strategies to avoid such things as overdose), their knowledge of hepatitis C is limited and vague. The marginal and stigmatised status of injecting both inside and outside the scene appears to contribute to an absence of information and communication about safer injecting and hepatitis C within the scene. Often information about safe injecting is perceived to lack relevance to scene participants and to be aimed at 'other' injecting drug users (IDU). The material discussed confirms the diversity of IDU and the crossover between social, sexual and drug networks. Whilst this poses challenges for education and prevention, the exploration of these networks or scenes has the potential to inform the content of education and prevention materials as well as identifying contexts for dissemination.

    Full Text Available Background: Swine influenza, also called swine flu, hog flu, and pig flu, is an infection caused by any one of the several types of swine influenza viruses. The World Health organization ( WHO raised a worldwide pandemic alert for swine flu on June 11, 2009 that was a first of its kind in the past 70 years. In India, the index cases were reported from Pune, Maharashtra. We witnessed a recent outbreak in India during late 2014 and early 2015. Methodology: A retrospective study was carried out to describe the clinical profile and outcome of the confirmed cases of swine flu who were admitted at our center between December 10, 2014 and May 11, 2015. The cases were confirmed by reverse transcriptase polymerase chain reaction (RT-PCR on respiratory specimens. Results: A total of 514 patients with symptoms suggestive of swine flu were tested for hemagglutinin type 1 and neuraminidase type 1 (H1N1 out of whom 88 were positive, which accounted for 17.12% positivity. The mean age was 31.15 years with a range of 11-90 years, with equal distribution among males and females (males: 45, females: 43. The epidemic peaked in the month of January (n = 44.50%.

    Acute kidney injury (AKI) is one of the most challenging and serious complications of pregnancy. We present our experience on the clinical profile and outcome of 57 patients with pregnancy-related AKI, of a total of 580 patients with AKI seen during the study period. This is a prospective single-center study in a civil hospital conducted from January to December 2010. The most common age group of the study patients was 20-25 years; 43.8% of the patients had received antenatal care. AKI was observed in the puerperium (n = 34), early pregnancy (n = 10) and late pregnancy (n = 13). The cause of AKI included puerperal sepsis (63.1%), pregnancy-induced hypertension (PIH) (33.33%), post-abortion (22.80%), ante-partum hemorrhage (APH) (14%) and post-partum hemorrhage (PPH) (8%). Complete, partial and no renal recovery was observed in 52.64%, 21.05% and 26.31% of the patients, respectively. Low platelet count and plasma fibrinogen and high bilirubin, D-dimer and activated partial thromboplast in time were observed more commonly in patients with partial recovery. Of the 57 patients, 50 received hemodialysis, three received peritoneal dialysis and seven patients were managed conservatively. A total of 13 patients developed cortical necrosis that was associated with sepsis in six, PPH and pre-eclampsia/eclampsia in three patients each and APH in one. Nine patients died, and the cause of death was septicemia in four, pre-eclampsia in three and APH and PPH in one patient each. In our study, puerperal sepsis was the most common etiological factor for pregnancy-related AKI. Prolonged oliguria or anuria were bad prognostic factors for renal recovery. Sepsis, thrombocytopenia, disseminated intra-vascular coagulation and liver involvement were associated with increased mortality. PMID:24969215

    Full Text Available O aumento do número de academias de ginástica na cidade de São Paulo, em conjunto com o aumento da oferta de diferentes suplementos no mercado, despertou interesse para o estudo do consumo de suplementos entre seus alunos. O uso de suplementos pelo público em geral não é bem quantificado e pouca informação sobre este assunto está publicada na literatura. O seu aparecimento no mercado tem sido mais rápido do que a elaboração de regulamentações e a realização de pesquisas científicas que comprovem seus efeitos na saúde dos consumidores e determinem a segurança de seu uso a longo prazo. Em uma amostra de 309 freqüentadores de sete academias de ginástica de São Paulo em 1999, 74 (23,9% consumiam algum tipo de suplemento, dos quais 77,0% eram do sexo masculino e 23,0% do sexo feminino.

    Full Text Available Personalized web search is able to satisfy individuals information needs by modeling long-term and short-term user interests based on user actions, browsed documents or past queries and incorporate these in the search process. In this paper, we propose a personalized search approach which models the user search preferences in an ontological user profile and semantically compares this model against user current query context to re-rank search results. Our user profile is based on the predefined ontology Open Directory Project (ODP so that after a user's search, relevant web pages are classified into topics in the ontology using semantic and cosine similarity measures. Moreover, interest scores are assigned to topics based on the users ongoing behavior. Our experiments show that re-ranking based on the semantic evidence of the updated user profile efficiently satisfies user information needs with the most relevant results being brought on to the top of the returned results.

    A new sunpsot model has been derived, consistent with the SUMER atlas data of Curdt, et al. and Mg II profile data from IRIS. Comparisons are made with Quiet-Sun results from both sources. It is necessary to include molecules in the sunspot model not only account for the low brightness temperatures near 1850 /AA but also for the density variations higher in the atmosphere. The minimum temperature is roughly 2500 K in the sunspot model and 4500 K for the quiet Sun. The Mg II H line profile is centrally reversed in both cases, with the peak intensity originating where the temperature rises abruptly from the minimum value. The line center is formed at the top of the chromosphere where the temperature rises abruptly from 10,000 K into the chromosphere-corona transition region. The calculated Mg II line center intensity is much smaller than observed, for models constrained by the EUV continuum data.

    The World Wide Web is a popular platform for providing eLearning applications to a wide spectrum of users. However – as users differ in their preferences, background, requirements, and goals – applications should provide personalization mechanisms. In the Web context, user models used...... by such adaptive applications are often partial fragments of an overall user model. The fragments have then to be collected and merged into a global user profile. In this paper we investigate and present algorithms able to cope with distributed, fragmented user models – based on Bayesian Networks – in the context...... of Web-based eLearning platforms. The scenario we are tackling assumes learners who use several systems over time, which are able to create partial Bayesian Networks for user models based on the local system context. In particular, we focus on how to merge these partial user models. Our merge mechanism...

    telephone service on drugs of abuse. METHODS: Data were collected by previously trained consultants using an electronic protocol throughout the first year of the service. Instruments were applied to find the sociodemographic profile, consumption pattern and dependence of drug users. Descriptive statistics was used to estimate distribution of variables, and the data are presented as frequencies. RESULTS: Throughout the study period there were 28,257 calls, of which 7,956 were included. In total there was higher prevalence of women, students, single individuals, older than 35 years, with incomplete primary education and family income lower than five minimum wages. Men aged 18-25 years were prevalent in the sample. The most frequently used drugs were tobacco, cannabis, alcohol and cocaine. Tobacco use was similar for both genders. Males used more illicit drugs. Most drug users were dependent, and men had higher rates of addiction to tobacco and solvents. CONCLUSIONS: These results outline the profile of individuals who seek care through a telephone service, showing the importance of these services for the population and guiding preventive actions.

    Full Text Available Emphasizing on effective factors in drug dependency and multiple drug relapse, is probably related to formation of personality models. These models are heavily affected by development orientation personality. Various researches show that attachment as a development factor has a decisive role in forming personality models. Hence, in one hand, the present research evaluates the relationship between attachment styles and drug dependency and ,in the other hand, it addresses the relationship between attachment /drug addiction and psychological profile. The statistical community of this research consists of all male referrals to self-introduced centers in Bushehr province in summer 1381. The sample group consists 100 individuals of this community and comparison group cnosists another 100 individuals who had no history of drug abuse. They were controlled by counterpart variables. The tools of this research are MCMI-II and adults’ attachment questionnaire. The satisfaction of validity and reliabilty of research literature are reported. Apllied statistical methods include χ² statistical test and profile analysis. To compare the individual distribution based on attachment style, χ² test is obtained meaningfully in P<0/05 level. Also, the results of profile analysis for evaluating the effect of drug addiction and attachment style on psychological profile is meaningful in P<0/01 level. In summary, the research shows that there is a relationship between attachment style and drug addiction as well as between attachment/addiction and psychological profile.

    PHEVs are discussed controversially. On the one hand, the evolutionary approach of a hybrid vehicle helps the consumer to adopt to electric driving, using the range extender when driving longer distances. On the other hand, PHEVs have a more complex propulsion system and a potentially low emission impact due to a low electric driving share. These factors, however, strongly depend on the consumers' driving and charging behavior. Therefore, this paper simulates realistic driving based on the na...

    Today many companies are employing a user-centered design (UCD) process, but for most companies, usability begins and ends with the usability test. Although usability testing is a critical part of an effective user-centered life cycle, it is only one component of the UCD process. This book is focused on the requirements gathering stage, which often receives less attention than usability testing, but is equally as important. Understanding user requirements is critical to the development of a successful product. Understanding Your Users is an easy to read, easy to implement, how-to guide on

    The jet fragmentation function and transverse profile for jets with 25 GeV < ptJet < 500 GeV and etaJet<1.2 produced in proton-proton collisions with a center-of-mass energy of 7 TeV are presented. The measurement is performed using data with an integrated luminosity of 36 pb^-1. Jets are reconstructed and their momentum measured using calorimetric information. The momenta of the charged particle constituents are measured using the tracking system. The distributions corrected for detector effects are compared with various Monte Carlo event generators and generator tunes. Several of these choices show good agreement with the measured fragmentation function. None of these choices reproduce both the transverse profile and fragmentation function over the full kinematic range of the measurement.

  7. USER RECOMMENDATION ALGORITHM IN SOCIAL TAGGING SYSTEM BASED ON HYBRID USER TRUST

    2013-01-01

    Full Text Available With the rapid growth of web 2.0 technologies, tagging become much more important today to facilitate personal organization and also provide a possibility for users to search information or discover new things with Collaborative Tagging Systems. However, the simplistic and user-centered design of this kind of systems cause the task of finding personally interesting users is becoming quite out of reach for the common user. Collaborative Filtering (CF seems to be the most popular technique in recommender systems to deal with information overload issue but CF suffers from accuracy limitation. This is because CF always been at-tack by malicious users that will make it suffers in finding the truly interesting users. With this problem in mind, this study proposes a hybrid User Trust method to enhance CF in order to increase accuracy of user recommendation in social tagging system. This method is a combination of developing trust network based on user interest similarity and trust network from social network analysis. The user interest similarity is de-rived from personalized user tagging information. The hybrid User Trust method is able to find the most trusted users and selected as neighbours to generate recommendations. Experimental results show that the hybrid method outperforms the traditional CF algorithm. In addition, it indicated that the hybrid method give more accurate recommendation than the existing CF based on user trust.

    This paper presents the case for a private (anonymous) personal profile of accessibility needs and preferences expressed in a Dublin Core format. It introduces the idea that this profile, identified only by a URI, is motivated by a desired relationship between a user and a resource or service. It assumes a new Dublin Core term DC: Adaptability and argues that, without any reference to disabilities, personal needs and preferences, including those symptomatic of common physical and cognitive disabilities, context or location, can be described in a common vocabulary to be matched by resource and service capabilities.%网络资源用户中具在残障的群体,他们或者在认知方面存在障碍(如失聪、听力障碍、失明、视力障碍等)或由于衰老而引起残障,而这些身体上或认知上的障碍意味着他们在浏览使用网络信息的时候需要有适合他们需要的特殊元数据和界面.尽管每个人的残障情况各有不同,但是每一种情况都会有一些共同点.通过建立元数据应用纲要来对这共同点进行描述,使信息系统能够根据元数据纲要描述的不同来调节网络信息的显示和功能,同时又保证残障用户的隐私权,是本文的主要内容.本文作者为都柏林元数据提出了一个新的元素:DC:Adaptability,用这个元素来描述具有残障的个人(匿名)元数据纲要,并且为该元素提出了一套规范词,包括显示、控制、内容三个大类共22个规范用词,这些规范词照顾到了用户的个人隐私权,不对残障种类和个人需要或偏好作任何暗示.作者还解释了该纲要不仅可以用来为残障用户提供个人化的信息显示和操作,而且也可以用来为一般用户提供个人化的系统显示.

    High performance computing at the Numerical Aerospace Simulation Facility at NASA Ames Research Center includes C90's, J90's and Origin 2000's. Not only is it necessary to protect these systems from outside attacks, but also to provide a safe working environment on the systems. With the right tools, security anomalies in the user s work environment can be deleted and corrected. Validating proper ownership of files against user s permissions, will reduce the risk of inadvertent data compromise. The detection of extraneous directories and files hidden amongst user home directories is important for identifying potential compromises. The first runs of these utilities detected over 350,000 files with problems. With periodic scans, automated correction of problems takes only minutes. Tools for detecting these types of problems as well as their development techniques will be discussed with emphasis on consistency, portability and efficiency for both UNICOS and IRIX.

    Abstract A synthetic cathinone called 4-methylethcathinone (4-MEC) emerged online in 2010, and was cyber-marketed to be a replacement for mephedrone. The study aimed to present user experiences of 4-MEC as reported on the Internet, with a focus on user profiles, sourcing and product characteristics, routes of administration, dosage, positive and undesirable effects, and comparisons to mephedrone. Twenty-three individual, anonymous trip reports of the sole use of 4-MEC, and 112 screenshots of general 4-MEC user discussion boards, were taken from a purposeful sample of public drug-related sites. A content textual analysis was conducted on extracted qualitative information and produced 41 categories compiled into five general themes: "Type of 4-MEC user"; "Sourcing, informed decision making, product characteristics, and quality assurance"; "Routes of administration, gauging of dosage, and consumption of other drugs"; "Time course effects and outcomes"; and "Comparisons with mephedrone." 4-MEC is sold as white beads, crystalline shards, or green balls. User motives centered on curiosity, pricing, and ease of web sourcing. Oral, nasal, injecting, eyeball, and rectal routes of administration were described. Testing for purity, "allergy testing," and gauging of dosage were common. Users described euphoric but short-lived effects, with little comedown. Continued research is vital to inform harm reduction.

    Full Text Available Web search engines are very important portal for ordinary people that are looking for useful information on the web. Generic search engine cannot identify the users search goals behind the query, if users enter improper keyword, ambiguous keyword and lack of user’s ability to express what they need exactly. Personalized web search overcome these above problem. Personalized web search is an effective way of search technique that aiming to provide customizing search results and also it improves the search quality. Personalized web search (PWS is ability thatidentifies different users needs who issue the same query for web searching for carry out data retrieval as a part of his/herinterests. User hesitated to disclose their privatepreference information to search engines which has become major issue in personalized web search. Thus, a balance must be stuck between user’s privacy and quality of search. In this paper we have surveyed user attitudes towards the privacy protection and here we have provided methodology for securing rich users profile while transferring the query to the server side using cryptography random4 algorithm. User profiles summarize a user’s specific interests into a hierarchical organisation according to particular interests. Two parameters used here minDetail and expRatio for specifying the privacy requirements to help the userto choose the content and degree of detail of profile information exposed to search engine.

    help users find, interpret, and obtain appropriate content quickly. The data access challenge for both SERVIR and USWP consisted of organizing a wide range of content for their respective user bases, which are diverse, international, and in some cases loosely characterized. The UX/UI design approach generated profiles of prototypical users and corresponding task flows and organizational schemes for their preferred types of content. Wireframe acceptance testing by SERVIR helped elicit and optimize how users interact with the information online. These approaches produced customized UIs and knowledge management strategies to address the data access challenges faced by each user type. Both studies revealed critical considerations for user experiences in developing nations (e.g., low-bandwidth internet connections, rolling power outages at data storage or network centers). For SERVIR, these findings influenced not only the portal infrastructure; they also informed the transition of the platform to a Cloud-based model, as well as the development of custom data delivery tools such as SMS and other mobile solutions. While SERVIR's data access solutions are customized for the network's community of users, they are also standardized and interoperable according to GEO and ISO standards, providing a model for other initiatives such as the ongoing USWP Portal development effort.

    1986-01-01

    The space station computing system must interface with a wide variety of users, from highly skilled operations personnel to payload specialists from all over the world. The interface must accommodate a wide variety of operations from the space platform, ground control centers and from remote sites. As a result, there is a need for a robust, highly configurable and portable user interface that can accommodate the various space station missions. The concept of an intelligent user interface executive, written in Ada, that would support a number of advanced human interaction techniques, such as windowing, icons, color graphics, animation, and natural language processing is presented. The user interface would provide intelligent interaction by understanding the various user roles, the operations and mission, the current state of the environment and the current working context of the users. In addition, the intelligent user interface executive must be supported by a set of tools that would allow the executive to be easily configured and to allow rapid prototyping of proposed user dialogs. This capability would allow human engineering specialists acting in the role of dialog authors to define and validate various user scenarios. The set of tools required to support development of this intelligent human interface capability is discussed and the prototyping and validation efforts required for development of the Space Station's user interface are outlined.

    This study presents an assessment of multiple approaches to determine the home and/or other important locations to a Twitter user. In this study, we present a unique approach to the problem of geotagged data sparsity in social media when performing geoinferencing tasks. Given the sparsity of explicitly geotagged Twitter data, the ability to perform accurate and reliable user geolocation from a limited number of geotagged posts has proven to be quite useful. In our survey, we have achieved accuracy rates of over 86% in matching Twitter user profile locations with their inferred home locations derived from geotagged posts.

    Some microblog services encourage users to annotate themselves with multiple tags, indicating their attributes and interests. User tags play an important role for personalized recommendation and information retrieval. In order to better understand the semantics of user tags, we propose Tag Correspondence Model (TCM) to identify complex correspondences of tags from the rich context of microblog users. The correspondence of a tag is referred to as a unique element in the context which is semantically correlated with this tag. In TCM, we divide the context of a microblog user into various sources (such as short messages, user profile, and neighbors). With a collection of users with annotated tags, TCM can automatically learn the correspondences of user tags from multiple sources. With the learned correspondences, we are able to interpret implicit semantics of tags. Moreover, for the users who have not annotated any tags, TCM can suggest tags according to users’ context information. Extensive experiments on a real-world dataset demonstrate that our method can effciently identify correspondences of tags, which may eventually represent semantic meanings of tags.

    From October 1, 2009 through September 30, 2013 (“contract period”), the Northeast Clean Energy Application Center (“NE-CEAC”) worked in New York and New England (Connecticut, Rhode Island, Vermont, Massachusetts, New Hampshire, and Maine) to create a more robust market for the deployment of clean energy technologies (CETs) including combined heat and power (CHP), district energy systems (DES), and waste heat recovery (WHR) systems through the provision of technical assistance, education and outreach, and strategic market analysis and support for decision-makers. CHP, DES, and WHR can help reduce greenhouse gas emissions, reduce electrical and thermal energy costs, and provide more reliable energy for users throughout the United States. The NE-CEAC’s efforts in the provision of technical assistance, education and outreach, and strategic market analysis and support for decision-makers helped advance the market for CETs in the Northeast thereby helping the region move towards the following outcomes: • Reduction of greenhouse gas emissions and criteria pollutants • Improvements in energy efficiency resulting in lower costs of doing business • Productivity gains in industry and efficiency gains in buildings • Lower regional energy costs • Strengthened energy security • Enhanced consumer choice • Reduced price risks for end-users • Economic development effects keeping more jobs and more income in our regional economy Over the contract period, NE-CEAC provided technical assistance to approximately 56 different potential end-users that were interested in CHP and other CETs for their facility or facilities. Of these 56 potential end-users, five new CHP projects totaling over 60 MW of install capacity became operational during the contract period. The NE-CEAC helped host numerous target market workshops, trainings, and webinars; and NE-CEAC staff delivered presentations at many other workshops and conferences. In total, over 60 different workshops

In particular, the emergence of online video publishing and sharing services is now one of the centers of attention on the Internet and allows users to share their content with large audiences.Available since February 2005, YouTube is the largest online video community with more than 2 billion page views per day. However, a web-based application is, by definition, above any culture, geography, or ideology, treating all equal without any type of distinction.With this research we attempted to determined the Portuguese profile of YouTube users. Is it possible to discover a pattern of Portuguese content on YouTube? What is the profile of these people? To make this possible we searched for Portuguese YouTube content through the technological facilities that the platform provides and cataloged these findings in terms of content type and user profile. From this set of information, we extracted quantitative and qualitative information that, after being properly treated and analyzed, enabled us to obtain the information that we sought.

    Web usage mining is a key knowledge discovery research and as such has been well researched. So far, this research has focused mainly on databases containing access log data only. However, many real-world databases contain users profile data and current solutions for this situation are still insufficient. In this paper we have a large database containing of user profile information together with user web-pages navigation patterns. The user profile data includes quantitative attributes, such as salary or age, and categorical attributes, such as sex or marital status. We introduce the concept of profile navigation patterns, which discusses the problem of relating user profile information to navigational behavior. An example of such profile navigation pattern might be 20% of married people between age 25 and 30 have the similar navigational behavior , where a, c, h, i, l are web pages in a web site. The navigation patterns may contain the generic traversal behavior, e.g. trend to backward moves, cycles etc. The objective of mining profile navigation patterns is to identify browser profile for web personalization. We give an algorithm for mining such profile navigation patterns. Our method (algorithm PNP) can discover profile navigation patterns efficiently. We also present new inclination measurements to identify the interesting profile navigational patterns. Experimental results show the efficiency and scalability of PNP.

    2013-01-01

    Mobility data has attracted the researchers for the past few years because of its rich context and spatiotemporal nature, where this information can be used for potential applications like early warning system, route prediction, traffic management, advertisement, social networking, and community finding. All the mentioned applications are based on mobility profile building and user trend analysis, where mobility profile building is done through significant places extraction, user's actual movement prediction, and context awareness. However, significant places extraction and user's actual movement prediction for mobility profile building are a trivial task. In this paper, we present the user similarity mining-based methodology through user mobility profile building by using the semantic tagging information provided by user and basic GSM network architecture properties based on unsupervised clustering approach. As the mobility information is in low-level raw form, our proposed methodology successfully converts it to a high-level meaningful information by using the cell-Id location information rather than previously used location capturing methods like GPS, Infrared, and Wifi for profile mining and user similarity mining.

    User engagement refers to the quality of the user experience that emphasizes the positive aspects of interacting with an online application and, in particular, the desire to use that application longer and repeatedly. User engagement is a key concept in the design of online applications (whether for desktop, tablet or mobile), motivated by the observation that successful applications are not just used, but are engaged with. Users invest time, attention, and emotion in their use of technology, and seek to satisfy pragmatic and hedonic needs. Measurement is critical for evaluating whether online

    Full Text Available The psychiatric reform in Brazil has replaced the hospital-centered model by the reintegration of users to their respective communities. The Center of Psychosocial Care (CAPS has been the main equipment in that scope. Objectives: To report the development of Supervised Practice in Occupational Therapy in a CAPS II unit in Curitiba, Parana state, Brazil. Methods: This is an experience report. It features the training field and describes the stages of the teaching and learning process which involved institutional observation, reporting and intervention proposal, collecting data about the users’ profile and attendances. The work focused the non-intensive users because they are close to hospital discharge. Results: We found that users of the non-intensive system, rather than crave the discharge, would like to return to the semi-intensive or intensive systems, aiming to regain sickness and transportation benefits, which are lost as users make progress. This fact denotes great contradictions in the system. We also attended intensive and semi-intensive systems users. Conclusions: The students’ learning included aspects such as direct contact with the institutional reality; knowledge about the health system, its limitations and contradictions; approach to users, their families, realities, socioeconomic conditions, desires, aspirations, or lack thereof; difficulties in engaging in meaningful occupations in their territories, limitations, and social stigma; working with frustrations, reflecting about ways to change the reality; in addition to expanded clinical practice, participating in the discussions and formulation of public policies on mental healthcare and social control.

    An integrated management architecture which called Adaptive Agent and Profile Management System (AAPMS) was proposed here. Using this system, users can get an adaptive service list according to their current condition (terminal capability, user preference, etc.). After choosing a service, the users only need to download a simple service agent to their mobile device and install it, and then the service agent will connect to the corresponding service provider. The users and the service providers can also manage their profiles using AAPMS.

    This document describes the PANTHER R&D Application, a proof-of-concept user interface application developed under the PANTHER Grand Challenge LDRD. The purpose of the application is to explore interaction models for graph analytics, drive algorithmic improvements from an end-user point of view, and support demonstration of PANTHER technologies to potential customers. The R&D Application implements a graph-centric interaction model that exposes analysts to the algorithms contained within the GeoGraphy graph analytics library. Users define geospatial-temporal semantic graph queries by constructing search templates based on nodes, edges, and the constraints among them. Users then analyze the results of the queries using both geo-spatial and temporal visualizations. Development of this application has made user experience an explicit driver for project and algorithmic level decisions that will affect how analysts one day make use of PANTHER technologies.

  14. Profile: the Philippine Population Information Network.

    Science.gov (United States)

    1991-06-01

    The profile of Philippine Population Information Network (POPIN) is described in this article as having changed management structure from the Population Center Foundation to the Government's Population Commission, Information Management and Research Division (IMRD) in 1989. This restructuring resulted in the transfer in 1990 of the Department of Social Welfare and Development to the Office of the President. POPIN also serves Asia/Pacific POPIN. POPCOM makes policy and coordinates and monitors population activities. POPIN's goal is to improve the flow and utilization of population information nationwide. The National Population Library was moved in 1989 to the POPCOM Central Office Building and became the Philippine Information Center. The collection includes 6000 books, 400 research reports, and 4000 other documents (brochures, reprints, conference materials, and so on); 42 video tapes about the Philippine population program and a cassette player are available. In 1989, 14 regional centers were set up in POPCOM regional offices and designated Regional Population Information Centers. There are also school-based information centers operating as satellite information centers. The Regional and school-based centers serve the purpose of providing technical information through collection development, cataloguing, classification, storage and retrieval, and circulation. The target users are policy makers, government and private research agencies, researchers, and faculty and students. Publications developed and produced by the Center include the 3rd Supplement of the Union Catalogue of Population Literature, the 1987-88 Annotated Bibliography of Philippine Population Literature (PPL), the forthcoming 1989-90 edition of the Annotated Bibliography of PPL, and a biyearly newsletter, POPINEWS. Microcomputers have been acquired for the Regional Centers, with the idea of computerizing POPIN. Computer upgrading is also being done within the IMRD to provide POPLINE CD

    Based on empirical evidence from a free word order language (German) we propose a fundamental revision of the principles guiding the ordering of discourse entities in the forward-looking centers within the centering model. We claim that grammatical role criteria should be replaced by indicators of the functional information structure of the utterances, i.e., the distinction between context-bound and unbound discourse elements. This claim is backed up by an empirical evaluation of functional centering.

  5. A profile of profiles: A meta-analysis of the nomological net of commitment profiles.

    Kabins, Adam H; Xu, Xiaohong; Bergman, Mindy E; Berry, Christopher M; Willson, Victor L

    2016-06-01

    Although the majority of empirical commitment research has adopted a variable-centered approach, the person-centered or profiles approach is gaining traction. One challenge in the commitment profiles literature is that names are attached to profiles based on the within-study comparison among profiles and their relative levels and shapes. Thus, it is possible that different studies name the same profiles differently or different profiles similarly because of the context of the other profiles in the study. A meta-analytic approach, combined with multilevel latent profile analysis (LPA) that accounts for both within- and between-sample variability, is used in this study to examine the antecedents and outcomes of commitment profiles. This helps solve the naming problem by examining multiple data sets (K = 40) with a large sample (N = 16,052), obtained by contacting commitment researchers who voluntarily supplied primary data to bring further consensus about the phenomenology of profiles. LPA results revealed 5 profiles (Low, Moderate, AC-dominant, AC/NC-dominant, and High). Meta-analytic results revealed that high levels of bases of commitment were associated with value-based profiles whereas low levels were associated with weak commitment profiles. Additionally, value-based profiles were associated with older, married, and less educated participants than the weak commitment profiles. Regarding outcomes of commitment, profiles were found to significantly relate to focal behaviors (e.g., performance, tenure, and turnover) and discretionary behaviors (e.g., organizational citizenship behaviors). Value-based profiles were found to have higher levels of both focal and discretionary behaviors for all analyses. Implications for the commitment and profile literature are discussed.

    Multi-user facilities serve as a resource for many universities. In 2010, a survey was conducted investigating possible changes and successful characteristics of multi-user facilities, as well as identifying problems in facilities. Over 300 surveys were e-mailed to persons identified from university websites as being involved with multi-user facilities. Complete responses were received from 36 facilities with an average of 20 years of operation. Facilities were associated with specific departments (22%), colleges (22%), and university research centers (8.3%) or were not affiliated with any department or college within the university (47%). The five most important factors to succeed as a multi-user facility were: 1) maintaining an experienced, professional staff in an open atmosphere; 2) university-level support providing partial funding; 3) broad client base; 4) instrument training programs; and 5) an effective leader and engaged strategic advisory group. The most significant problems were: 1) inadequate university financial support and commitment; 2) problems recovering full service costs from university subsidies and user fees; 3) availability of funds to repair and upgrade equipment; 4) inability to retain highly qualified staff; and 5) unqualified users dirtying/damaging equipment. Further information related to these issues and to fee structure was solicited. Overall, there appeared to be a decline in university support for facilities and more emphasis on securing income by serving clients outside of the institution and by obtaining grants from entities outside of the university.

    The Flow Analysis Software Toolkit, FAST, is a software environment for visualizing data. FAST is a collection of separate programs (modules) that run simultaneously and allow the user to examine the results of numerical and experimental simulations. The user can load data files, perform calculations on the data, visualize the results of these calculations, construct scenes of 3D graphical objects, and plot, animate and record the scenes. Computational Fluid Dynamics (CFD) visualization is the primary intended use of FAST, but FAST can also assist in the analysis of other types of data. FAST combines the capabilities of such programs as PLOT3D, RIP, SURF, and GAS into one environment with modules that share data. Sharing data between modules eliminates the drudgery of transferring data between programs. All the modules in the FAST environment have a consistent, highly interactive graphical user interface. Most commands are entered by pointing and'clicking. The modular construction of FAST makes it flexible and extensible. The environment can be custom configured and new modules can be developed and added as needed. The following modules have been developed for FAST: VIEWER, FILE IO, CALCULATOR, SURFER, TOPOLOGY, PLOTTER, TITLER, TRACER, ARCGRAPH, GQ, SURFERU, SHOTET, and ISOLEVU. A utility is also included to make the inclusion of user defined modules in the FAST environment easy. The VIEWER module is the central control for the FAST environment. From VIEWER, the user can-change object attributes, interactively position objects in three-dimensional space, define and save scenes, create animations, spawn new FAST modules, add additional view windows, and save and execute command scripts. The FAST User Guide uses text and FAST MAPS (graphical representations of the entire user interface) to guide the user through the use of FAST. Chapters include: Maps, Overview, Tips, Getting Started Tutorial, a separate chapter for each module, file formats, and system

    An analysis is presented of the uses of metadata from four aspects of database operations: (1) search, query, retrieval, (2) ingest, quality control, processing, (3) application to application transfer; (4) storage, archive. Typical degrees of database functionality ranging from simple file retrieval to interdisciplinary global query with metadatabase-user dialog and involving many distributed autonomous databases, are ranked in approximate order of increasing sophistication of the required knowledge representation. An architecture is outlined for implementing such functionality in many different disciplinary domains utilizing a variety of off the shelf database management subsystems and processor software, each specialized to a different abstract data model.

    The negative consequences of cyberbullying are becoming more alarming every day and technical solutions that allow for taking appropriate action by means of automated detection are still very limited. Up until now, studies on cyberbullying detection have focused on individual comments only, disregarding context such as users’ characteristics and profile information. In this paper we show that taking user context into account improves the detection of cyberbullying.

    un alto nivel de no adhesión y un bajo promedio de consultas por paciente; la raíz más relevante es la demanda espontánea; y la psiquiatría logra la mayor búsqueda de los usuarios. CONCLUSIÓN: Concluye que hay la necesidad de modificaciones operacionales, tales como la formación de grupos terapéuticos, la creación de un protocolo estándar para que los profesionales sigan y la realización de nuevas investigaciones o la replicación de este estudio.INTRODUCTION: After the deinstitutionalization of psychiatry, substitute services have become the main resource for people in need of mental health care. Thus, categorizing the clients of such services is of major importance. OBJECTIVE: The goal of this study is to outline an epidemiological profile of the population of users of a psychosocial attention center in the state of Rio Grande do Sul, Brazil. RESULTS: The most prevalent diagnostic categories were mood disorders, stress-related neurotic disorders and somatoform disorders. There is a low compliance to treatment prescriptions and a low rate of medical visits for each patient. The most relevant source of referral is the spontaneous demand by clients, and psychiatry is the service with the highest demand. FINDINGS: Operational changes were shown to be required, such as the creation of therapy groups and of a standard protocol to be followed by caregivers, the reassignment of psychiatric patients, and the conduction of further research. The replication of this study may be useful as well.

Semi-structured interviews were carried out with eleven users of the Psychosocial Care Center, located in the countryside of São Paulo state. The data were submitted to Theme Analysis, based on Minayo. The themes which came from the data analysis, allowed the configuration of three topics. In the first one, the user experiences the treatment on an organicist focus of the care, assessed by the medical professional value, in the medicine-based approach and the symptom control. The second topic brings the perception of the space in CAPS as a helping scenario of social exchanges. And the third topic is about the therapeutic process as being towards the daily life of the users. Based in these data, we could reflect on the directions of the new facilities in mental health, the CAPS.El presente estudio tiene por objetivo describir el funcionamiento de un centro de atención psicosocial y aprender como los usuarios atendidos por este servicio perciben el proceso terapéutico ofrecido.

    From 2010 to 2012, librarians at the University of Florida Health Science Center Library (HSCL) used an online survey and focus groups to gather user input on preferences for an ideal library space. User input guided the HSCL's renovation plans and put a clear focus on enhancing technology, improving infrastructure, enabling group collaboration, and creating comfortable spaces. Additional communication with users during renovation was vital in ensuring continued usability of nonconstruction spaces and shared understanding of the construction timeline. While specific user suggestions are particular to the HSCL, overall themes and methods for eliciting input will be useful to other libraries undergoing space planning.

    coffee», a methadone maintenance program, a room for supervised drug consumption, a place for personal hygiene, and medical and psychosocial follow-up. The particularity of this program lies in its integration within an outpatient drug treatment center forming part of a general hospital. Methods: We performed a descriptive study using qualitative methods. Theoretical sampling was conducted. Twelve in-depth interviews and one focus group composed of eight users were carried out. Information analysis was based on grounded theory. Literal transcriptions were coded and subsequently sorted into broad categories. Three researchers participated in this process and finally a fourth researcher triangulated the results. Results: Five dimensions were identified in the users´ discourse: accessibility, service, relationship, localization, and identity. Each consisted of several topics that were evaluated based on the participants´ experiences and expectations. The dimension of identity emerged as a distinctive element in patient-program bonding. Conclusions: The users´ overall evaluation of the program was positive. Facilitators and barriers influencing patient-program bonding were identified and participants suggested ways to remove barriers. The coexistence among users of the harm reduction program and patients treated conventionally provoked ambivalence but the team's management was deemed helpful in easing the difficulties arising from this situation.

    prevención del VIH y las ITS, combinando estrategias on-line y off-line.Objectives: To describe the attitudes of men who have sex with men (MSM toward online HIV/sexually-transmitted infection (STI prevention programs and to identify and characterize user profiles with regard to their attitudes toward online prevention programs. Method: A survey in gay venues or via the internet was completed by 2,044 participants from Madrid, Barcelona, Bilbao and San Sebastián (Spain. The survey explored socio-demographic variables, sexual behavior and other risk behaviors associated with HIV infection, as well as attitudes toward online prevention programs. The statistical analysis included factor analysis and non-hierarchical cluster analysis. Results: Most MSM had positive attitudes towards online HIV/STI prevention programs. Factor analysis revealed two factors: online prevention aimed at interaction and online prevention aimed at information. Based on these factors, three user profiles were identified: users oriented toward informative and interactive online prevention (53.5%, users oriented toward interactive online prevention (25.9% and users were not oriented toward online prevention (20.7%. On characterizing these profiles, we observed a significant presence of men who were not interested in online prevention among those with a lower educational level, bisexual men and HIV-positive men. Conversely, those most receptive to online prevention were men self-identified as gay, those with a bachelors degree, those who had been tested for HIV and those who were HIV-negative. Conclusion: The internet can facilitate sexual health promotion among MSM. Characterization of user profiles offers the possibility of segmenting prevention programs and of combining online and offline strategies.

    This paper describes a case-based approach to user profiling in a Personal Travel assistant (based on the 1998 FIPA Travel Scenario). The ap-proach is novel in that the user profile is made up of a set of cases capturing previous interactions rather than as a single composite case. This has the advan-tage that the profile is always up-to-date and also allows for the borrowing of cases from similar users when coverage is poor.

    The Strategic Defense Initiative Organization has created data centers for midcourse, plumes, and backgrounds phenomenologies. The Backgrounds Data Center (BDC) has been designated as the prime archive for data collected by SDIO programs. The BDC maintains a Summary Catalog that contains 'metadata,' that is, information about data, such as when the data were obtained, what the spectral range of the data is, and what region of the Earth or sky was observed. Queries to this catalog result in a listing of all data sets (from all experiments in the Summary Catalog) that satisfy the specified criteria. Thus, the user can identify different experiments that made similar observations and order them from the BDC for analysis. On-site users can use the Science Analysis Facility (SAFE for this purpose. For some programs, the BDC maintains a Program Catalog, which can classify data in as many ways as desired (rather than just by position, time, and spectral range as in the Summary Catalog). For example, data sets could be tagged with such diverse parameters as solar illumination angle, signal level, or the value of a particular spectral ratio, as long as these quantities can be read from the digital record or calculated from it by the ingest program. All unclassified catalogs and unclassified data will be remotely accessible.

    2006-10-01

    This paper describes recent advances in the field of autostereoscopic display development and introduces an appropriate integration of a novel user interaction technology. Beside technical aspects of the developed autostereoscopic display technology, the paper includes topics of our video-based interaction technique and introduces promising applications of autostereoscopic single user displays. Based on results of the European ATTEST project, the Fraunhofer Institute for Telecommunications (HHI) has developed the Free2C 3D display technology, which provides free positioning of a single viewer. The optics of the Free2C displays is designed such that extremely low crosstalk, excellent color reproduction and high brightness are achieved. Simple and intuitive interaction is a requirement for multi-modal 3D displays. For this reason, a novel technology has been integrated into the control console that can recognize a persons' hand and its gestures. Displayed 3D objects floating in front of the screen can be rotated by simple gestures and virtual buttons can be pressed by pointing at them (virtual 3D touch screen). Several applications are currently used by customers and have been presented at trade shows, exhibitions and showrooms. Feasible applications are based on computer generated content, live video created by stereoscopic cameras and films stored on hard disk. Immersive media presentations are one promising application for attractive stereoscopic representations. The Free2C Kiosk and the 3D Media Center combine a high-resolution autostereoscopic 3D display with a video-based hand-gesture recognition device for direct manipulation of virtual 3D objects floating in front of the screen.
