    This paper introduces our work on how to use image mining techniques to detect SARS, the severe acute respiratory syndrome, automatically as the prototype of computer aided detection/diagnosis (CAD) system. Data used in this paper are digitalized PA(posterior anterior) X-ray images stored in the real-life picture archiving and communication system (PACS) of the 2nd Affiliation Hospital of Guangzhou Medical College. Association rule mining was applied first but results showed there was no significant difference between the locations of the lesions or infiltrate. Classification based on image textures was performed. A sample set contains both the pneumonia and SARS X-ray images was built in the first place. After modeling each sample by a feature vector, the sample set was partitioned to match the detection purpose: classification. Three methods were used: C4.5, neural network (NN) and CART. Final result shows that 70.94% SARS cases can be detected by CART. Data preparation, segmentation, feature extraction and data mining steps, with corresponding techniques are included in this paper. ROC charts and confusion matrix by all three methods are given and analyzed.

    Nitti, Davide O.; Bovenga, Fabio; Morea, Alberto; Rana, Fabio M.; Guerriero, Luciano; Greco, Mario; Pinelli, Gianpaolo

    2012-09-01

    This study is aimed at exploring the potentials of SAR Interferometry (InSAR) to aid Unmanned Aerial Vehicles (UAV) navigation. The basic idea is to infer both position and attitude of an aerial platform by inspecting the InSAR phase derived by a real time SAR interferometer mounted onboard the platform. Thanks to the expected favorable conditions in terms of geometrical sensitivity as well as signal coherence, the InSAR phase field can be used to derive the terrain elevation. By using both approximated position and attitude values of the platform as well as a reference Digital Terrain Model (DTM) from a mission database available onboard, it is possible to generate a synthetic InSAR phase model to be compared w.r.t. that derived by SAR observations. The geometrical transformation needed to match these two terrain models depends on the difference between position and attitude values derived by the instruments available on board and their actual values. Hence, this matching provides a feedback to be used for adjusting position and attitude. In order to assess the reliability of the proposed approach, we evaluated the interferometric sensitivity to changes in position and attitude. This analysis defines the limits of applicability of the InSAR-based approach and provides indications and requirements on geometric and radiometric parameters.

    The hearing impaired population has been increasing; many people suffer from hearing problems. To deal with this difficulty, various types of hearing aids are being rapidly developed. In particular, fully implantable hearing aids are being actively studied to improve the performance of existing hearing aids and to reduce the stigma of hearing loss patients. It has to be of small size and low-power consumption for easy implantation and long-term use. The objective of the study was to implement a small size and low-power consumption successive approximation register analog-to-digital converter (SAR ADC) for fully implantable hearing aids. The ADC was selected as the SAR ADC because its analog circuit components are less required by the feedback circuit of the SAR ADC than the sigma-delta ADC which is conventionally used in hearing aids, and it has advantages in the area and power consumption. So, the circuit of SAR ADC is designed considering the speech region of humans because the objective is to deliver the speech signals of humans to hearing loss patients. If the switch of sample and hold works in the on/off positions, the charge injection and clock feedthrough are produced by a parasitic capacitor. These problems affect the linearity of the hold voltage, and as a result, an error of the bit conversion is generated. In order to solve the problem, a CMOS switch that consists of NMOS and PMOS was used, and it reduces the charge injection because the charge carriers in the NMOS and PMOS have inversed polarity. So, 16 bit conversion is performed before the occurrence of the Least Significant Bit (LSB) error. In order to minimize the offset voltage and power consumption of the designed comparator, we designed a preamplifier with current mirror. Therefore, the power consumption was reduced by the power control switch used in the comparator. The layout of the designed SAR ADC was performed by Virtuoso Layout Editor (Cadence, USA). In the layout result, the size of the

  17. Engaging students in geodesy: A quantitative InSAR module for undergraduate tectonics and geophysics classes

    Science.gov (United States)

    Taylor, H.; Charlevoix, D. J.; Pritchard, M. E.; Lohman, R. B.

    2013-12-01

    In the last several decades, advances in geodetic technology have allowed us to significantly expand our knowledge of processes acting on and beneath the Earth's surface. Many of these advances have come as a result of EarthScope, a community of scientists conducting multidisciplinary Earth science research utilizing freely accessible data from a variety of instruments. The geodetic component of EarthScope includes the acquisition of synthetic aperture radar (SAR) images, which are archived at the UNAVCO facility. Interferometric SAR complements the spatial and temporal coverage of GPS and allows monitoring of ground deformation in remote areas worldwide. However, because of the complex software required for processing, InSAR data are not readily accessible to most students. Even with these challenges, exposure at the undergraduate level is important for showing how geodesy can be applied in various areas of the geosciences and for promoting geodesy as a future career path. Here we present a module focused on exploring the tectonics of the western United States using InSAR data for use in undergraduate tectonics and geophysics classes. The module has two major objectives: address topics concerning tectonics in the western U.S. including Basin and Range extension, Yellowstone hotspot activity, and creep in southern California, and familiarize students with how imperfect real-world data can be manipulated and interpreted. Module questions promote critical thinking skills and data literacy by prompting students to use the information given to confront and question assumptions (e.g. 'Is there a consistency between seismic rates and permanent earthquake deformation? What other factors might need to be considered besides seismicity?'). The module consists of an introduction to the basics of InSAR and three student exercises, each focused on one of the topics listed above. Students analyze pre-processed InSAR data using MATLAB, or an Excel equivalent, and draw on GPS and

    To determine the knowledge, attitude and willingness of preclinical dental students to treat HIV/AIDS patients in the future. The sample comprised 150 students of both genders drawn from the third and fourth year dental students of the University of Benin, Benin City. One hundred and fifty questionnaires were self-administered, with 139 (92.6%) retrieval. The parameters measured were knowledge, status, immunization against hepatitis B virus, willingness to treat, knowledge of post exposure prophylaxis (PEP) and its protocol in the of University of Benin Teaching hospital (UBTH). Data analysis showed that 100 (71.9%) students rated their knowledge of HIV/AIDS as high and very high. Sixty-three (45.3%) students thought that HIV was a contagious disease while 46 (33.1%) felt HIV was more infectious than tuberculosis or any of the strains of hepatitis virus. Only 59 (42.4%) students knew their HIV status. One hundred and twenty seven (91.4%) students felt that professional oral health care will be beneficial to HIV/AIDS patients; while fifty-one students (36.7%) are not prepared to administer dental care to HIV/AIDS patients in future. Majority of respondents adjudged health workers to be more at risk than sex workers. Forty students comprising 28.8% of the study population had been immunized against Hepatitis B. Ninety- four (67.7%) students had no knowledge of PEP while 122 (87.8%) students did not know the PEP protocol in UBTH. Although a large number of these students claim to be knowledgeable about HIV/AIDS. It is obvious that a true understanding is lacking. Concerted effort should be made to change their perception by implementing a curriculum designed to enhance the knowledge of dental students; if we hope to save HIV/AIDS patients from the discrimination of future healthcare givers.

    Science.gov (United States)

    Hossain, Mohammad Bellal; Kabir, Alamgir; Ferdous, Hasina

    To examine the levels and predictors of knowledge on HIV and AIDS, a survey was conducted among 392 tertiary level students in the University of Dhaka, Bangladesh. Students demonstrated a high knowledge of transmission and prevention of HIV and AIDS yet with considerable misconception. All students said that unprotected sex with an HIV-positive man or woman can transmit the HIV virus to a negative man or woman but at the same time 43.6% of students believed that there is a preventive vaccine for HIV and 39.8% understood that HIV can be cured if it is diagnosed early. Multivariate regression analysis indicated that the students who had more knowledge on HIV and AIDS were: older boys, fathers having more income, business or service as father's occupation, having more mass media exposure, being senior students, living in a university dormitory, and being students of faculty of arts, social sciences, and science. The findings of this study suggest that a special course on health education, including risk perceptions of HIV and AIDS and issues related to sexual and other high risk behavior, should be included in the course curricula irrespective of disciplines at tertiary levels.

    Full Text Available Aims First case of Acquired Immuno Deficiency Syndrome (AIDS in Nepal was reported in the year 1988. Nurses are an integral part of the healthcare system and should be knowledgeable in providing care to AIDS patients. This study assessed the knowledge of nursing students towards HIV/AIDS, and the association (if any between the knowledge scores of the nursing students with their selected demographic variables. Materials and methods A cross sectional study was conducted evaluating the nursing student knowledge using a self designed questionnaire. The correct answers were given a score of ‘1’ and wrong answers were given a score of ‘0’ (total possible maximum score ‘18’. Results Among the total 165 nursing students, 121 of them filled the questionnaire (response rate of 73.33% and all of them were females. The mean ± SD age of the respondents was 18.3 ±1.75 years. The median (IQR of the overall total scores was 13.0 (11.5-15.0. There was an association between the knowledge scores of the respondents with ‘age’ (p=000, ‘course of the study’ (p=0.001. However, there was no statistically significant association between the knowledge scores with the ‘year of study’ of the respondents (p=0.109, ‘mode of finance’ (0.611 and ‘native’ of the students (0.173. Conclusion The study suggested that nursing students have a poor overall knowledge on AIDS and especially areas such as post exposure prophylaxis.The findings also suggested the need for providing adequate knowledge to the students during their regular class room teaching and clinical postings.

    Stepping acquired immunodeficiency syndrome (AIDS), severe acute respiratory syndrome (SARS) as another type of disease has been threatening mankind since late last year. Many scientists worldwide are making great efforts to study the etiology of this disease with different approaches. 13 species of SARS virus have been sequenced. However, most people still largely rely on the traditional methods with some disadvantages. In this work, we used Wolfram approach to study the relationship among SARS viruses and between SARS viruses and other types of viruses, the effect of variations on the whole genome and the advantages in the analysis of SARS based on this novel approach. As a result, the similarities between SARS viruses and other coronaviruses are not really higher than those between SARS viruses and non-coronaviruses.

    The use of smartphone is increasing day by day for personal as well as professional purpose. They are becoming a more suitable tool for advancing education in developing countries. Mobile access to information and many applications are successfully harnessed in health care. Smartphones are also becoming popular as an effective educational tool. The present study was conducted to evaluate the use of smartphones as an educational tool amongst the medical students. The study also aimed at identifying the common medical application used by the students. It was an observational cross-sectional study carried out amongst medical students of private medical institute in India. A validated 16 point, structured, open-ended, questionnaire regarding ownership and use of smart phones was self-administered to 446 medical students. Data were analysed using SPSS and open ended questions were analysed by summative content analysis. Among the study population, 96% owned a smartphone -Android based 72.4%, i phone 13.0%, Windows based Nokia phones 7% and Blackberry 3.6%. Common medical applications used by the students were Anatomy and Medical Dictionary in First MBBS; Medical Dictionary, Medscape and Google/Wikipedia in Second MBBS; and Medscape, Google/Wikipedia and Prognosis/Diagnosis in Third MBBS. More than 90% students, reported to have technological skills to use smartphones, for medical education, communication and instant access during bedside teaching. Advertently, 37.2% students felt if smartphones are used for clinical purposes, they will need to spend less time with patients. Almost 79.4% felt that smartphones should be introduced in MBBS course. Smartphone use amongst medical students as learning aid for various medical applications is rapidly advancing. But it will be worthwhile to study whether use of smartphones has any impact on the grades of the students before introducing them in medical schools.

  19. Computer Aided Drug Design for Multi-Target Drug Design: SAR /QSAR, Molecular Docking and Pharmacophore Methods.

    2017-01-01

    Multi-target drugs against particular multiple targets get better protection, resistance profiles and curative influence by cooperative rules of a key beneficial target with resistance behavior and compensatory elements. Computational techniques can assist us in the efforts to design novel drugs (ligands) with a preferred bioactivity outline and alternative bioactive molecules at an early stage. A number of in silico methods have been explored extensively in order to facilitate the investigation of individual target agents and to propose a selective drug. A different, progressively more significant field which is used to predict the bioactivity of chemical compounds is the data mining method. Some of the previously mentioned methods have been investigated for multi-target drug design (MTDD) to find drug leads interact simultaneously with multiple targets. Several cheminformatics methods and structure-based approaches try to extract information from units working cooperatively in a biomolecular system to fulfill their task. To dominate the difficulties of the experimental specification of ligand-target structures, rational methods, namely molecular docking, SAR and QSAR are vital substitutes to obtain knowledge for each structure in atomic insight. These procedures are logically successful for the prediction of binding affinity and have shown promising potential in facilitating MTDD. Here, we review some of the important features of the multi-target therapeutics discoveries using the computational approach, highlighting the SAR, QSAR, docking and pharmacophore methods to discover interactions between drug-target that could be leveraged for curative benefits. A summary of each, followed by examples of its applications in drug design has been provided. Computational efficiency of each method has been represented according to its main strengths and limitations.

    Full Text Available A descriptive cross sectional study was conducted in an Irish University among undergraduate students in 2012. A web questionnaire consisted of items related to HIV/AIDS knowledge, behaviour and attitudes was sent to all undergraduate students aged 18 years or above. Despite the fact that majority of students were aware about the transmission of HIV/AIDS, this study showed that students were less likely to translate their knowledge about HIV/AIDS transmission into healthy behaviour. In addition, they engaged in risky sexual behaviour which increases the likelihood of acquiring HIV/AIDS and other sexually transmitted diseases.

    2013-01-01

    Full Text Available Activators of PPARγ, Troglitazone (TGZ, Rosiglitazone (RGZ, and Pioglitazone (PGZ were introduced for treatment of Type 2 diabetes, but TGZ and RGZ have been withdrawn from the market along with other promising leads due cardiovascular side effects and hepatotoxicity. However, the continuously improving understanding of the structure/function of PPARγ and its interactions with potential ligands maintain the importance of PPARγ as an antidiabetic target. Extensive structure activity relationship (SAR studies have thus been performed on a variety of structural scaffolds by various research groups. Computer-aided drug discovery (CADD approaches have also played a vital role in the search and optimization of potential lead compounds. This paper focuses on these approaches adopted for the discovery of PPARγ ligands for the treatment of Type 2 diabetes. Key concepts employed during the discovery phase, classification based on agonistic character, applications of various QSAR, pharmacophore mapping, virtual screening, molecular docking, and molecular dynamics studies are highlighted. Molecular level analysis of the dynamic nature of ligand-receptor interaction is presented for the future design of ligands with better potency and safety profiles. Recently identified mechanism of inhibition of phosphorylation of PPARγ at SER273 by ligands is reviewed as a new strategy to identify novel drug candidates.

    Full Text Available The objective of this study was to assess students' knowledge, attitudes and practices on HIV and AIDS. A questionnaire was administered to a cross section of 259 Chinese undergraduates. Respondents were asked to provide information about knowledge and attitudes about HIV/AIDS. Study results indicated that the majority of undergraduates had a moderate level of HIV and AIDS knowledge, acceptance and attitudes towards people with HIV and AIDS. Boys had more acceptance and positive attitudes towards people with HIV and AIDS than girls. Students majoring in medicine performed better (more knowledgeable and accepting than non-medical students. Differences between students with various monthly expenditures were found-- 6.2% of students had 3-5 sexual partners which has rarely been found in Chinese students; most students did not know HIV VCT centers and most students did not show their confidence for controlling of HIV and AIDS in China. In conclusion, students’ knowledge about HIV/AIDS was uneven. A peer educational program to talk about self esteem, healthy sexual attitudes, being human-accepting and loving should be developed in the near future.

    This study investigated dental and dental hygiene students' a) perceptions of their education about treating patients with HIV infections/AIDS, b) knowledge of universal precautions, c) attitudes towards treating these patients and patients perceived to be at risk for HIV infections, and d) evaluations of potential curricular activities such as discussion groups with HIV-infected patients. Data were collected with self-administered questionnaires from 315 dental and 89 dental hygiene students. On average, dental students reported having learned about this topic in fever courses than dental hygiene students. However, dental students answered significantly more knowledge questions about universal precautions correctly than did dental hygiene students. This knowledge increased over the program course. Male students had significantly stronger negative attitudes towards patients at risk for or with HIV infections/AIDS than female students. Overall, dental and dental hygiene students responded positively to the suggested methods for including more material about patients with HIV infections/AIDS such as case studies, discussion groups, and closely supervised clinical experiences. This study shows that dental and dental hygiene students are interested in learning more about treating patients with HIV infections/AIDS. It also adds information to previous research on factors involved in the dental healthcare providers' decisions to treat patients at risk for or with HIV infections/AIDS. The implications of these findings for curriculum development efforts are discussed.

Students showed low willingness (9.2%) to assist patients and low confidence (36.1%) in their education about HIV/AIDS patients. Students recommended HIV testing for health care professionals (69.4%) and patients (75.9%) before surgical procedures. Students knew little about Post Exposure Prophylaxis (18.5%) or about the time for HIV to develop into AIDS (57.4%). About 40% of students were unaware of the inability of antivirals to treat HIV/AIDS. Students had low awareness for opportunistic infections (18.5%), and low agreement on competency to treat and counsel HIV patients (12.9%).

    There is a paucity of studies that have systematically and comprehensively investigated the knowledge level, attitudes and the pattern of sexual behaviours related to HIV and AIDS in higher education settings in sub-Saharan Africa in general and Tanzania in particular. This study attempted to fill a void in knowledge. A cross-sectional descriptive design was used, employing a self-administered questionnaire as the main data collection tool. More than 400 higher education students completed a questionnaire assessing their knowledge, attitudes and behaviours related to HIV and AIDS. About three quarters of respondents demonstrated comprehensive knowledge about HIV and AIDS, and the majority of respondents expressed positive attitudes towards people living with HIV and AIDS. Despite demonstrating high knowledge level about HIV and AIDS, the results show that sexual behaviours among students in higher education are characteristically risky, and do not significantly differ from youth in the general population.

    To evaluate the knowledge and perception of undergraduate students of the University of Nigeria with regards to HIV/AIDS and determine their sexual behaviour. This was a cross sectional descriptive study. Pre-tested structured questionnaires were administered to the students to collect relevant information on their sociodemographic characteristics, HIV/AIDS awareness, sexual behaviour, willingness to screen and disposition to people living with HIV/AIDS RESULTS: Five hundred and seventy nine students between 16 to 40 years of age responded, out of 600. Majority (55%) heard about HIV/AIDS through the media. Seventy two percent believed viruses cause HIV/AIDS but 27% thought it was God's anger or witches. Forty four percent were (genitally) sexually active or engaging in pre/extramarital sexual intercourse and only two-thirds of these used condoms for these purposes. Ninety one percent of those not using condoms simply did not like it or admitted it was unavailable. More than 70% had never had a HIV screening test, mostly due to reluctance or fear. Ninety two percent would lovingly care for a HIV/AIDS patient. Information on HIV/AIDS and sexual behaviour to this vulnerable and most economically important group is still inadequate, as reflective of the society. Appropriate information, education and communication strategies must be packaged towards these students, with efforts made to reinforce their positive trends.

    2015-01-01

    Human immunodeficiency virus/acquired immunodeficiency syndrome (HIV/AIDS) is a complex healthcare problem. Research has demonstrated that negative attitudes affect healthcare provision. The purpose of this study was to compare nursing students' attitudes using the AIDS Attitude Scale (AAS). A descriptive, cross-sectional study was conducted in nursing schools in Istanbul, Turkey, and in Upstate New York (NY). Baccalaureate nursing students (n = 613) from both countries completed the questionnaire. Demographic data, overall AAS attitudes, and attitudes within each subscale were compared. Analyses included frequency and percentages of the grouped variables, arithmetic means and standard deviations, t-test for independent samples, and multiple analysis of variance. Upstate NY students' mean total AAS scores were significantly more positive toward HIV+ patients than Turkish students'. Scores for Professional Resistance and Emotions subscales were significantly more positive for the Upstate NY students, but Fear of Contagion was not. Upstate NY students had more negative attitudes in the contexts of job risk and eating in a restaurant where the chef has AIDS; more professional resistance to referring patients and training specialists for HIV/AIDS patients; and lower tender feelings for people with HIV/AIDS (p < .01 for each). Improvement in students' attitudes is beneficial for promoting nonjudgmental, compassionate care for the HIV+ population. © 2014 Wiley Periodicals, Inc.

    Murray, Kimberly

    The purpose of this study was to determine the effects of online learning aids on student performance and engagement. The thirty-five participants of the current study were students enrolled in two sections of a junior level Medical Microbiology laboratory. The experimental section was required to spend ten minutes each week on an online learning aid. The online program, StudyMate(TM), was used to present text and images in the form of flash cards, multiple choice questions, matching, and crossword puzzles. Both groups completed the Index of Learning Style survey, an initial engagement survey at the start of the course, and a final engagement survey at the end of the course. Statistical analysis showed no significant differences between the groups at the start of the course or after the course was completed for learning style, science grade point average, overall grade point average, initial engagement or final engagement. A moderate correlation was found between microbiology course and laboratory grades and a reflective learning style.

    Full Text Available A qualitative, exploratory and descriptive study was conducted with the purpose of exploring and describing the views of undergraduate nursing students on caring for HIV/AIDS patients. The study population consisted of BCur III nursing students studying at the Medical University of Southern Africa (Medunsa. Participants were purposively selected. Focus group interviews were used as a data collection instrument. Guided by a group moderator and responding to a central research question, participants shared their views about caring for HIV/AIDS patients. Tesch’s qualitative method of data analysis, as described by Cresswell (1994:155, was used to analyse the data. Caring for HIV/AIDS patients evoked emotions such as fear, anger and frustration among undergraduate nursing students. Students expressed needs such as the acquisition of knowledge and a reduction in the stigmatisation of patients with HIV/ AIDS, while the data analysis revealed demands such as more intensive clinical accompaniment by lecturers and antiretroviral therapy delivery by government. Suggested solutions included student participation in HIV/AIDS prevention campaigns and the upholding of patients’ rights. Curriculum innovation was recommended to improve students’ knowledge of HIV/AIDS and to ensure the provision of quality care for these patients.

    2007-10-01

    Full Text Available Presents part of the findings of a study that was carried out at the University of Botswana to determine in general how HIV/AIDS information is disseminated to and used by undergraduate students. Both qualitative and quantitative approaches were used. A survey design was used to study a population of 9000 plus undergraduate students. Questionnaires and interviews were used to collect data. SPSS was used to analyse quantitative data while qualitative data was analysed using thematic categorization.Key findings revealed that the HIV/AIDS information disseminated to students include information on behaviour change; information on HIV/AIDS prevention; transmission and treatment. The means of disseminating information to students include the use of multiple channels such as the university Health and Wellness Centre, Lectures, peer groups, seminars/workshops, students meetings, the University Clinic and the library. The study found that the most common media used to disseminate information to students include video, print, CDs and verbal means. Finally, factors that affect access to and use of HIV/AIDS information by students include: religious orientations, substance abuse, low income levels, multiple relationships, age and gender.There is need for the University of Botswana to review its overall approach of disseminating HIV/AIDS information to students in order to make it more effective. Moreover, strong liaison among agencies involved in the fight against the spread of HIV/AIDS at the University is needed. Furthermore, a more rigorous research into issues of students’ attitudes and values in relation to HIV/AIDS is needed. Similarly, more efforts are needed to create awareness and educate students on the dangers associated with substance abuse, multiple partners and practicing unprotected sex. The need to encourage testing for HIV/AIDS among students is needed so that appropriate interventions can be put in place.The world over, HIV/AIDS has

    The objectives of this study were to describe knowledge, attitudes, and self-awareness, and to identify predictable factors affecting HIV/AIDS prevention among Thai university students. A cross sectional survey was conducted among 844 first-year university students using a validated, self-administered questionnaire as a research instrument. The questionnaire included items assessing knowledge, attitudes, self-awareness, and HIV/AIDS preventive behaviors. It was found that 22.4% of the subjects received various sexually provocative media. The university student's knowledge, attitudes, self-awareness, and preventive behaviors toward HIV/AIDS were at a high level. The results from the multiple regression analysis identified self-awareness, faculty, sex, sexual-risk score, income-per-month, GPA, and knowledge as significant independent predictors of HIV/AIDS preventive behaviors. These factors contributed to 36.9% of the explanation of HIV preventive behaviors, and the strongest predictor was found to be self-awareness. Scientific information, and useful and productive life skills are needed to educate the university students regarding the health consequences of HIV/AIDS. An integrated approach is strongly suggested for creating knowledge, attitudes, and awareness to control the spread of HIV/AIDS among young people.

    Full Text Available Abstract Background The use of Indigenous Knowledge (IK can help students to form schemas for interpreting local phenomena through the prism of what they already know. The formation of schemas related to HIV/AIDS risk perception and prevention is important for individuals to form local meanings of the HIV/AIDS epidemic. The objective of this study was to explore the indigenous names and symptoms of HIV/AIDS among High School students in Namibia Methods Focus group discussions were used to collect qualitative data on indigenous names and symptoms of HIV/AIDS from students in 18 secondary schools located in six education regions. Data were grouped into themes. Results People living with HIV/AIDS were called names meaning prostitute: ihule, butuku bwa sihule, and shikumbu. Names such askibutu bwa masapo (bone disease,katjumba (a young child,kakithi (disease, andshinangele (very thin person were used to describe AIDS. Derogatory names like mbwa (dog, esingahogo (pretender, ekifi (disease, and shinyakwi noyana (useless person were also used. Other terms connoted death (zeguru, heaven; omudimba, corpse, fear (simbandembande, fish eagle; katanga kamufifi, (hot ball, and subtle meaning using slang words such as 4 × 4, oondanda ne (four letters, desert soul, and mapilelo (an AIDS service organization. Typical (body wasting and non-typical (big head, red eyes symptoms of HIV were also revealed. Conclusions The study determined students' IK of the names and symptoms of HIV/AIDS. Programmes to prevent/manage adolescent HIV infection and stigma may be strengthened if they take students' indigenous understandings of the disease on board.

    1993-09-01

    A project was undertaken in Grahamstown to assess the level of AIDS awareness, attitudes towards AIDS and opinions as to how and whether education programmes for schoolchildren should be planned. Opinions were canvassed initially by means of a questionnaire to three groups of professionals who could become involved in AIDS education programmes: student teachers and lecturers in the Department of Education at Rhodes University, theology students at the local Theological College and health care professionals at Settlers' Hospital. Each group was then asked to attend a lecture about AIDS at which slides were shown of actual cases of the disease and its complications. A slightly modified version of the original questionnaire was then administered after 6 weeks to assess any changes in awareness, attitudes and opinions. The study did not attempt to establish the permanence of any such changes.

    Full Text Available Background: India estimates third highest number of HIV infections in the world, with about 2.4 million people currently living with HIV/AIDS. Adequately trained and sensitized healthcare professionals can play a vital role in combating this epidemic. Limited studies have explored knowledge and attitudes of medical students relating to HIV/AIDS, particularly in the eastern part of India. Methods: The present cross sectional study explored knowledge and attitudes of first year MBBS, BDS & BPT students of Kalinga Institute of Medical Sciences (KIMS, Bhubaneswar, Odisha on HIV/AIDS using a self-administered questionnaire. Data thus collected were analyzedand relevant statistics were calculated. Knowledge and attitude scores were determined and analysis of variance (ANOVA test was used to examine the equality between the groups. Results: All students scored low on the overall knowledge scale (<10/15. Specifically, knowledgewas low on modes of transmission and treatment. Attitudinal scores in the areas of precautions and need for training on HIV was low for all the three streams.The willingness to treat HIV/AIDS patient was found to be high amongst study participants. Conclusion: There is a need and scope to provide correct and detailed information on HIV/AIDS for new entrants in medical and allied health sciences to help them acquire adequate knowledge and develop appropriate attitudes towards HIV/AIDS.

    A survey was conducted to assess the knowledge of 30 oral hygiene (OH I & II) and 79 dental students (BCHD III & VI) on HIV infection and AIDS. A questionnaire consisting of twenty-nine questions based on the 'agree-disagree' format was prepared for this study. Clinical slides were projected to assess students' ability to identify oral manifestations of HIV infection. Most students agreed that HIV-sero-positive people were entitled to the same dignity and respect as those who were suffering from other illnesses. Students were concerned about treating sero-positive patients. They would preferably receive training in the management of these patients in a controlled environment. They had a poor perception of the risk of infection following needle-stick injury and whether HIV could be transmitted through contact with saliva. Most students felt that they had insufficient lectures on HIV/AIDS and had practically no clinical exposure to HIV-sero-positive patients.

    The purpose of the study was to gain information about patients' and dental students' attitudes concerning AIDS and dentistry. Opinions of patients and students at a Midwestern dental school were surveyed. The dental students' responses were not as consistent as the patient responses. Both groups felt there was a risk to patients and dentists of HIV infection. Both groups had confidence in the CDC infection control guidelines. The patient responses to the testing questions were significantly more positive than the student responses. The patients responded positively to the concept that healthcare professionals had the right to ask patients to be tested and to being required to be tested if a healthcare provider is accidentally stuck by a needle used on a patient. The dental students were more cautious with both issues. Patients would use knowledge about a healthcare provider's HIV status and the office treatment of AIDS patients to determine if they should continue treatment at that dental office.

    Full Text Available This inverstigation is a quasi-experimental study comparing the effects of two methods of health education on student's knowledge and attitudes about AIDS. The target population consisted of 218 male undergraduates studying in Payame Noor University in Saghez, Iran. A random sample of 106 students was selected using sample random sampling method. The students were randomly divided into two experimental groups. One group was educated about AIDS using a direct method of health education and indirect method was used for the other group. Using pretest/posttest method of data collection, analysis of the data showed a significant difference between each group's knowledge and attitudes before and after the educational programs. Comparison of the two educational methods showed no significant difference on student's knowledge about AIDS. However, method one (using a direct method of health education was significantly more effective in changing student's attitudes towards AIDS than method 2 (using an indirect method of health education.

    The purpose of this pilot study was to illustrate international university students' knowledge of HIV and AIDS, attitudes towards HIV and AIDS and risk behaviours in relation to HIV and AIDS. Questionnaires were posted to 140 students, and 32 responded. Data were analysed statistically. The results indicated a fairly good knowledge level of HIV and AIDS. The majority of students were well aware of the general facts about HIV and AIDS, modes of transmission and main risk groups, and they were also aware of the universal precautions. The majority of students had positive attitudes towards persons with HIV and AIDS and were willing to care for them. The students identified well with risk behaviours. Most agreed that their knowledge level of HIV and AIDS did affect their risk behaviours, while others felt it was a matter of choice, personal attitude and practice. Choice is a determining factor for decisions made by students in relation to HIV and AIDS. Future research focusing on factors influencing these choices that put them at risk of contracting the HIV virus is recommended. Students also need to be enlightened on matters concerning symptoms of HIV and AIDS.

    2011-06-01

    The purpose of this project was to describe dental students' use of lecture podcasts versus written lecture transcripts as learning aids under three different circumstances: studying for an exam, reviewing an attended lecture, and reviewing a missed lecture. Additional analyses were performed to see whether demographic differences (e.g., age, gender, language skills, and computer skills) or grade differences were associated with preferences for using podcast versus written lecture transcripts of class notes. Fifty-one percent (n=171) of the second-year dental students at the New York University College of Dentistry voluntarily participated in this survey. The major findings were that 1) a high percentage of students (70-92 percent) used one or both aids in all three utilization circumstances with a consistent preference for podcast use, especially when reviewing a missed lecture; 2) course grades were not associated with the preferred use of either lecture aid; and 3) over half the students listened to the podcasts at speeds that were one and one-half or two times faster than normal speech, especially younger students. Further studies are warranted to delve into the current student generation's preferred learning styles and the resultant learning outcomes associated with those preferences.

    Full Text Available Background: Residents are expected to have transition of care (ToC skills upon entering graduate medical education. It is unclear whether experience and training during medical school is adequate. Objective: The aim of the project was to assess: 1 graduating medical students’ ability to perform ToC in a crisis situation, and 2 whether using a cognitive aid improves the ToC quality. Methods: The authors developed simulation scenarios for rapid response teams and a cognitive aid to assist in the ToC during crisis situations. Graduating medical students were enrolled and randomly divided into teams of three students, randomly assigned into one of two groups: teams using a cognitive aid for ToC (CA, or not using a cognitive aid (nCA. In the scenario, teams respond to a deteriorating patient and then transfer care to the next provider after stabilization. Three faculty reviewed the recording to assess completeness of the ToC and the overall quality. A completeness score was expressed as a fraction of the maximum score. Statistical analysis was performed using a t-test and Mann-Whitney U test. Results: A total of 112 senior medical students participated: CA n=19, nCA n=17. The completeness score of the ToC and overall quality improved when using the cognitive aid (completeness score: CA 0.80±0.06 vs. nCA 0.52±0.07, p<0.01; ToC quality: CA 3.16±0.65 vs. nCA 1.92±0.56, p<0.01. Participants’ rating of knowledge and comfort with the ToC process increased after the simulation. Conclusion: The completeness of information transfer during the ToC process by graduating medical students improved by using a cognitive aid in a simulated patient crisis.

    Young people are of particular importance in state policies against AIDS. The present study investigated the attitude toward HIV/AIDS and related socio-cultural factors among 600 high school students in Shiraz, Iran. The method of sampling is a stratified one and the instrument for collecting data is a self-administrated questionnaire. In this research, attitude has three dimensions-knowledge, emotion and tendency to action. Descriptive statistics showed that students did not have enough knowledge about HIV/AIDS. The 44.3% of students had low knowledge, 36.9% moderate knowledge and only 18.8% had high knowledge. Also the results indicated that attitude for 69.8% of student has in middle level, 15.4% positive and 14.9% negative. Moreover, results suggested that loyalty to Islamic religious beliefs have an important role on attitude toward this disease. Major of study, sex, mother's occupation and use of some mass media such as books and newspapers were other main influencing factors in the students' attitude. Furthermore, this study showed that parent education, major of study, father's occupation and use of books and the Internet are the most important variables affecting on the participants' knowledge. Age, sex, parents' education, religious beliefs, use of some mass media such as TV, the internet, newspapers, satellite and books affect emotion. Finally, there is a relationship between religious beliefs, sex and major of study, use of satellite, television, radio and books with tendency to action.

    Various studies have reported that university students, who are mostly young people, rarely use existing HIV/AIDS preventive methods. Although studies have shown that young university students have a high degree of knowledge about HIV/AIDS and HIV modes of transmission, they are still not utilising the existing HIV prevention methods and still engage in risky sexual practices favourable to HIV. Some variables, such as awareness of existing HIV/AIDS prevention methods, have been associated with utilisation of such methods. The study aimed to explore factors that influence use of existing HIV/AIDS prevention methods among university students residing in a selected campus, using the Health Belief Model (HBM) as a theoretical framework. A quantitative research approach and an exploratory-descriptive design were used to describe perceived factors that influence utilisation by university students of HIV/AIDS prevention methods. A total of 335 students completed online and manual questionnaires. Study findings showed that the factors which influenced utilisation of HIV/AIDS prevention methods were mainly determined by awareness of the existing university-based HIV/AIDS prevention strategies. Most utilised prevention methods were voluntary counselling and testing services and free condoms. Perceived susceptibility and perceived threat of HIV/AIDS score was also found to correlate with HIV risk index score. Perceived susceptibility and perceived threat of HIV/AIDS showed correlation with self-efficacy on condoms and their utilisation. Most HBM variables were not predictors of utilisation of HIV/AIDS prevention methods among students. Intervention aiming to improve the utilisation of HIV/AIDS prevention methods among students at the selected university should focus on removing identified barriers, promoting HIV/AIDS prevention services and providing appropriate resources to implement such programmes.

    An exploratory, descriptive, comparative study with a quantitative approach, whose objective was to compare the knowledge of high school students from two public state schools of Peruíbe, SP, Brazil, about Human Immunodeficiency Virus (HIV) and Acquired Immunodeficiency Syndrome (AIDS), in the years 1999 and 2010. In both of these years, the predominant population studied was female students, under 18 years old, unmarried and white. A statistically significant difference was found with respect to knowledge about HIV/AIDS among the groups studied. It was found that even with ten-year interval between the studies, the two groups of students did not consider themselves vulnerable to HIV and presented doubts as to the correct knowledge about the topic, which indicates the need for a continuous approach with young adolescents.

    In Uganda, curbing the spread of HIV/AIDS has largely depended on public and private media messages about the disease. Media campaigns based on Uganda’s cultural norms of communication are metaphorical, analogical and simile-like. The topic of HIV/AIDS has been introduced into the Senior Three (Grade 11) biology curriculum in Uganda. To what extent do students’ pre-conceptions of the disease, based on these media messages influence students’ development of conceptual understanding of the disease, its transmission and prevention? Of significant importance is the impact the conceptions students have developed from the indirect media messages on classroom instruction on HIV/AIDS. The study is based in a theoretical framework of conceptual change in science learning. An interpretive case study to determine the impact of Ugandan students’ conceptions or perceptions on classroom instruction about HIV/AIDS, involving 160 students aged 15-17, was conducted in four different Ugandan high schools: girls boarding, boys boarding, mixed boarding, and mixed day. Using questionnaires, focus group discussions, recorded biology lessons and informal interviews, students’ preconceptions of HIV/AIDS and how these impact lessons on HIV/AIDS were discerned. These preconceptions fall into four main categories: religious, political, conspiracy and traditional African worldviews. Results of data analysis suggest that students’ prior knowledge is persistent even after biology instructions. This has implications for current teaching approaches, which are mostly teacher-centred in Ugandan schools. A rethinking of the curriculum with the intent of offering science education programs that promote understanding of the science of HIV/AIDS as opposed to what is happening now—insensitivity to misconceptions about the disease—is needed.

  1. AIDS knowledge and sexual activity among Flemish secondary school students: a multilevel analysis of the effects of type of education

    Science.gov (United States)

    2010-01-01

    Background The behavior of adolescents puts them at an increased risk for HIV and other STIs, and their knowledge about HIV/AIDS is often inadequate. An understanding of how AIDS knowledge and sexual activity co-vary among Flemish secondary school students and of how education type, specifically, affects these students is limited. This study addresses the question of whether the effects of education type on HIV/AIDS knowledge and sexual activity are independent of the socio-demographic characteristics of the students. Methods Data from the Flemish Educational Assessment survey, which collected data from a large representative sample of third- and fifth-grade high school students (N = 11,872), were used. Data were analyzed using multilevel logistic and Poisson regression techniques. Results There is an indication that type of education affects both an adolescent's sexual activity and his/her AIDS knowledge; these effects prove robust for differences in socio-economic backgrounds. Students in lower status education types are more likely to be sexually active and to have poorer AIDS knowledge. The relationship between AIDS knowledge and sexual activity is, however, more complex. Although students in education types with poorer AIDS knowledge are more sexually active, within each of these groups the sexually active have better AIDS knowledge than the non-sexually active. There is also evidence of active information seeking by sexually active students, which leads to improved AIDS knowledge. Conclusion These findings are consistent with the literature on the role of the educational system in the reproduction of social inequalities. Students from lower status education types are at increased sexual risk compared to those from higher status types. There is also evidence of active information seeking by sexually active students, which leads to improved AIDS knowledge. PMID:20092623

    Full Text Available A cross-sectional survey was done among students of four senior secondary schools including two boys and two girls schools of rural Delhi to know the knowledge, attitude, belief and practices regarding AIDS. A large majority (83.0% of students though had heard about AIDS, yet majority of them did not know the possible methods for prevention of AIDS. There were only 27.1% girls who knew about regular condom usage. Half of them had permissible attitude for pre-maritial sex, while sexual activity was observed in one-fourth students. Students were less reluctant to discuss about AIDS than sex, and teachers were preferred as compared to parents in this regard. School is an ideal setting to educate adolescents regarding HIV/AIDS transmission and safer sex behaviour.

    The aim of this study is to investigate the sexual campus culture of students at the University of the Free State (UFS), by specifically focussing on gender and culture as patterns of high-risk sexual behaviour. The sample consisted of 396 participants, 211 female and 185 male students, with a mean age of 19.9 years. Sixty one percent (61%) of the students associated themselves with a Western cultural background and 39% with an African cultural background. In this article an exposition is provided on information collected in a survey conducted at the UFS to help provide a better understanding of risk factors for HIV infection among UFS students in comparison with the behaviour patterns of students at other universities. Stereotypes identified as known risk factors making students at other universities more vulnerable to HIV and high-risk sexual behaviour, were also found among UFS students. Results indicated the existence of the following statistical significant correlations: African cultural students, gender and their viewpoint that there is a stronger relationship between homosexuality and HIV/AIDS; their opinion that HIV/AIDS is more strongly associated with African students. Data obtained from this survey questionnaire show that even if students have a great deal of knowledge to their disposal, and even if they recognised that they were personally at risk, some students' sexual practices and risk-taking behaviour remained unchanged. Despite the fact that the majority of students (85%) concluded that it is unacceptable for a woman or a man to have more than one sexual partner and that it is better to wait until marriage before engaging in a sexual relationship, 17% of male students (Western culture) and 4% of female students indicated that they have had more than five sexual partners in their lives. Statistical significant correlations also existed between African students, gender and their sexual activity the last six months. Contradictory to research results

    Encounters between dentists and patients with HIV/AIDS are bound to rise due to increased prevalence and emerging new treatments. This study assessed dental students' knowledge about transmission and oral manifestations of HIV/AIDS, and their attitudes towards patients regarding obligations to treat. Out of 109 students in 4 years of a 6-year dental undergraduate program, 106 responded to a questionnaire on knowledge of and attitudes towards HIV/AIDS. Knowledge and attitude scores were analyzed with Kruskal-Wallis one-way anova and the gender differences with the Wilcoxon signed-rank test. The median score for students' overall knowledge was 39.5 (67%; maximum possible 59). The median knowledge scores for males and females were 38 and 40 respectively, although the difference was not statistically significant. The knowledge levels in Year 4 (42.5 ± 4.7), Year 3 (44 ± 6.5), and Year 2 (42 ± 5.8), were similar but significantly higher than in Year 1 (33 ± 7.9; P differences within genders and years of study. Although the level of knowledge of the senior students was higher than that of the first years, the negative attitudes remained largely unchanged.

    Full Text Available Abstract Background Acquired Immunodeficiency Syndrome (AIDS has become an important public health hazard in Iran. It is believed that AIDS-related knowledge does not necessarily translate into behavior modification. Hence, it has been suggested that culturally appropriate educational campaigns should be implemented to obtain satisfactory outcomes. Here, we evaluated the female high school students' attitude towards HIV/AIDS in Tabriz, Iran to assess the cultural needs for the related educational programs and to discover sources of information about AIDS. Results Anonymous, self-administered questionnaires were filled by the young female students. Among 300 students, 91% agreed that being an HIV carrier should not be an obstacle to obtaining education and employment. Moreover, 72.5% of the students declared that the community should be informed of HIV-positive people. In addition, one-tenth declared that they would feel extremely uncomfortable towards their HIV infected classmate. In addition, only 16% of the students stated that they would continue to shop at HIV infected grocer's store. The mass media and the experts were the major source and the most reliable source of information about AIDS, respectively. Conclusion Tabrizian female students have overall negative attitudes towards HIV/AIDS. HIV/AIDS related educational campaigns should target the students, society and the families with emphasizing the leading roles of health staff.

    Acquired immunodeficiency syndrome (AIDS) is a major health problem worldwide. The number of infected people is increasing daily. Knowledge and awareness toward prevention and control of the disease is necessary among both educated and illiterate people. This study is aimed at assessing the knowledge and awareness about human immunodeficiency virus (HIV)/AIDS among undergraduate students studying in a technical institute in Gorakhpur, Uttar Pradesh, India. A community-based cross-sectional study was conducted among youths aged 15-30 years studying in a technical institution in Gorakhpur. Data were collected using a semistructured questionnaire developed with the help of existing literature, from 250 participants (students). The main source of information was the television; knowledge about the difference between HIV/AIDS was satisfactory. The findings showed that the knowledge about modes of prevention (blood checkup, needle/syringe sterilization) was satisfactory. There were several misconceptions about the modes of transmission of the disease, such as through mosquito bites, eating/drinking, and kissing. The knowledge of the study population was satisfactory, and there is a need for innovation and comprehensive education to impart better knowledge and understanding about HIV/AIDS.

    2009-01-01

    This study examined students' attitudes toward computer-aided instruction (CAI), specifically neuroanatomy learning modules, to assess which components were primary in establishing these attitudes and to discuss the implications of these attitudes for successfully incorporating CAI in the preparation of health care providers. Seventy-seven masters degree, entry-level, health care professional students matriculated in an introductory neuroanatomy course volunteered as subjects for this study. Students independently reviewed the modules as supplements to lecture and completed a survey to evaluate teaching effectiveness. Responses to survey statements were compared across the learning modules to determine if students viewed the modules differently. Responses to individual survey statements were averaged to measure the strength of agreement or disagreement with the statement. Responses to open-ended questions were theme coded, and frequencies and percentages were calculated for each. Students saw no differences between the learning modules. Students perceived the learning modules as valuable; they enjoyed using the modules but did not prefer CAI over traditional lecture format. The modules were useful in learning or reinforcing neuroanatomical concepts and improving clinical problem-solving skills. Students reported that the visual representation of the neuroanatomical systems, computer animation, ability to control the use of the modules, and navigational fidelity were key factors in determining attitudes. The computer-based learning modules examined in this study were effective as adjuncts to lecture in helping entry-level health care students learn and make clinical applications of neuroanatomy information.

    Full Text Available This study aimed to assess acquired immune deficiency syndrome (AIDS-related knowledge, attitudes, and risk perception among Saudi nursing students, and to identify predictors of their willingness to provide care for patients with AIDS. A cross-sectional study of 260 baccalaureate nursing students at King Saud bin-Abdulaziz University for Health Sciences, Riyadh, Saudi Arabia, was done using a previously validated instrument. Students’ knowledge percentage mean score (PMS on AIDS was 72.93 ± 10.67 reflecting an average level of knowledge. There were many misconceptions about how AIDS is transmitted, for example, use of same toilets and bathrooms and washing clothes together (24.9%, swimming (53.7%, and coughing and sneezing (49.6%. Nursing students reported an overall negative attitude toward AIDS, with a PMS of 43.48 ± 9.21. The majority of students agreed that AIDS patients should be isolated from other patients (83%, and should not share the room with other noninfected patients (81.8%, and some reported that people living with AIDS deserve what has happened to them (24.7%. After controlling for confounders, students’ poor knowledge and negative attitude were associated only with having never been given nursing education as their primary university education “Stream 2 students” (p = .012 and p = .01, respectively. These findings have implications for development of teaching strategies and curricular approaches for nursing to address this health care issue.

    Podcasting has recently emerged as an important information technology tool for health professionals. Podcasts can be viewed online or downloaded to a user computer or a handheld multimedia device like a portable MP3 player, smart phone and tablet device. The principal advantage of the podcast is that the presentation of information need not be linked with any particular time or location. Since students are familiar with newer technology tools and may be using it on a regular basis, video podcast could serve as a convenient tool for students to help remember both conceptual and factual information. The purpose of this study was to assess the attitude of first year dental students towards video podcast supplementation and to assess the efficacy of video podcast as a teaching aid in comparison to text book reading. First year dental students were recruited for this study. A didactic lecture class was conducted for the students (n=100). The students were then randomly divided into two groups. Students present in group A (n=46) underwent a video podcast session followed by a multiple choice question test. This was followed by student feedback to assess the usefulness of video podcast. Students belonging to group B (n=54) had a study session for 20 minutes followed by the MCQ test. Students then underwent the video podcast session followed by feedback to assess the utility of video podcast. Mann-Whitney U test was applied to compare the difference in the median MCQ score between the two groups. The findings revealed a significant gain in the median MCQ score in the intervention group (group A) when compared to control group (Group B). In the feedback form, 89% of students agreed that the video podcast might be useful as it would enable them to view slides and hear the lectures repeatedly. Students who underwent the video podcast session performed significantly better in the MCQ test compared to students who underwent text book reading alone. This demonstrates an

    Background The Middle East and North Africa (MENA) region is among the top two regions in the world with the fastest growing HIV epidemic. In this context, risks and vulnerability are high as the epidemic is on the rise with evidence indicating significantly increasing HIV prevalence, new HIV infections and AIDS-related deaths. Objective The aim of the survey was to assess HIV/AIDS knowledge and attitudes related to HIV/AIDS among a wide group of university students in the United Arab Emirates (UAE). Methods In a cross-sectional survey, a total sample of 2,294 students (406 male; 1,888 female) from four universities in three different Emirates in the UAE were approached to take part in the study. Students self-completed a questionnaire that was designed to measure their knowledge and attitudes to HIV/AIDS. Results The overall average knowledge score of HIV.AIDS was 61%. Non-Emirati and postgraduates demonstrated higher levels of knowledge compared to Emirati and undergraduate students respectively. No significant differences between males and females; and marital status were found. Eighty-five percent of students expressed negative attitudes towards people living with HIV, with Emirati and single students significantly holding more negative attitudes compared to non-Emiratis and those that are married respectively. Conclusions The findings provide strong evidence that there is a need to advocate for appropriate National HIV/AIDS awareness raising campaigns in universities to reduce the gaps in knowledge and decrease stigmatizing attitudes towards people living with HIV/AIDS.

    There is a lot of information available about various oral hygiene aids used for the maintenance of oral hygiene and the prevention of oral diseases but the reason why people choose a particular product is under-reported. This study sought to assess the knowledge, attitudes and behaviour of choosing oral hygiene aids among students of management institutes in Ghaziabad, India. A cross-sectional survey was conducted in five management institutes selected by simple random sampling and data were collected from 1224 students by self-administered structured validated questionnaire. The study showed that toothbrush (96.8%) and toothpaste (95.2%) were the main products used for the maintenance of oral hygiene. The most commonly used brand dentifrices were Colgate and Close-Up (47%, 23.3%) and in toothbrush, Oral B and Colgate (48.4%, 30.9%), respectively. A particular brand of toothpaste was preferred by 66.4% of the subjects because of childhood and parental use, which was the most influential factor (56.9%). Bristle design was the main criterion for choosing a toothbrush (44.9%), followed by bristle consistency (33.1%). The most commonly used toothbrushes were of soft bristle consistency (51.2%) and 10.9% of the subjects did not know the type of bristle consistency present in their toothbrush. Selection of oral hygiene products was based more on parental influence and there seems to be a lack of knowledge and awareness about how to choose a dentifrice and toothbrush.

    Full Text Available This paper presents the configuration and digital signal processing details of a tablet-based hearing aid transmitting wirelessly to standard earphones, whereby the tablet performs full sound processing rather than solely providing a means of setting adjustment by streaming to conventional digital hearing aids. The presented device confirms the recognized advantages of this tablet-based approach (e.g., in relation to cost, frequency domain processing, amplification range, versatility of functionality, component battery rechargeability, and flags the future wider-spread availability of such hearing solutions within mainstream healthcare. The use of a relatively high sampling frequency was found to be beneficial for device performance, while the use of optional off-the-shelf add-on components (e.g., data acquisition device, high fidelity microphone, compact wireless transmitter/ receiver, wired headphones are also discussed in relation to performance optimization. The easy-to-follow configuration utilized is well suited to student learning/research instrumentation projects within the health and biomedical sciences. In this latter regard, the presented device was pedagogically integrated into a flipped classroom approach for the teaching of bioinstrumentation within an Allied Health Sciences School, with the subsequent establishment of positive student engagement outcomes.

    Cross contamination of HIV is a real threat today. Dental treatment often includes direct contact with a patient's blood and saliva, therefore dental professionals can be easily exposed to HIV microorganisms. Hence, it is essential to gain insight into dental students' knowledge and attitude towards HIV patients. A cross-sectional survey of 186 clinical year dental students (year 3, 4 and 5) in the 2015-2016 academic session at the Faculty of Dentistry, Melaka-Manipal Medical College (MMMC), Manipal University, Melaka volunteered to participate in the study. A self-administered questionnaire was used to determine their knowledge and attitude towards HIV/AIDS patients. Among 137 respondents (females 74.5% and males 25.6%), 40.9% were Malay, 46.7% were Chinese, 10.2% were Indian and 2.2% were others. The majority had an excellent (41.6%) to good (56.2%) knowledge and only (18%) had a professional attitude. There was a statistically significant association of knowledge with gender (P = 0.009) and ethnicity (P = 0.024), However, no association was found between attitude and gender (P = 0.756) or ethnicity (P = 0.792), or between knowledge and attitude (P = 0.473) of dental students. Dental students' knowledge was not significantly associated with attitude. However, knowledge was associated with gender and ethnicity, but no association was found between age and knowledge and between age, gender, or ethnicity and attitude.

    2012-01-01

    Background Universities in Cameroon are playing an active part in HIV/AIDS research and much of this research is carried out by students, usually for the purpose of a dissertation/thesis. Student theses/dissertations present research findings in a much more comprehensive manner and have been described as the stepping-stone of a budding scientist’s potential in becoming an independent researcher. It is therefore important to verify how students handle issues of research ethics. Method Theses/dissertations on HIV/AIDS that described research studies involving the use of human research participants were screened to verify if research ethics approval and informed consent were obtained and documented. The contents of the consent forms were also qualitatively analyzed. Results Of 174 theses/dissertations on HIV, ethics approval was documented in 17 (9.77%) and informed consent in 77 (47.83%). Research ethics approval was first mentioned at all in 2002 and highly reported in the year 2007. Evidence of ethics approval was found for the first time in 2005 and informed consent first observed and evidenced in 1997. Ethics approval was mostly reported by students studying for an MD (14.01%) and was not reported in any Bachelors’ degree dissertation. Informed consent was also highly reported in MD theses (64.58%) followed by undergraduate theses (31.58%). Voluntary participation and potential benefits of the study were some of the common aspects dealt with in most of the consent forms. The right to discontinue participation in the study and management of residual samples were scarcely ever mentioned. Conclusions Overall, and given the current state of the art of research ethics around the world, student-scientists in Cameroon would seem to be merely kidding with research ethics. It is thus essential that training in health research ethics (HRE) be incorporated in the curriculum of universities in Cameroon in order that the next generation of scientists may be better

    Full Text Available BACKGROUND: Human immunodeficiency virus (HIV and acquired immune deficiency syndrome (AIDS are among the most complex health problems in the world. Young people are at high risk of HIV and AIDS infections and are, therefore, in need of targeted prevention. School-based HIV/AIDS health education may be an effective way to prevent the spread of AIDS among adolescents. METHODS: The study was a school-based intervention conducted in three middle schools and two high schools in Wuhan, China, which included 702 boys and 766 girls, with ages from 11 to 18 years old. The intervention was a one-class education program about HIV/AIDS for participants. HIV/AIDS knowledge, attitude, and high-risk behaviors were investigated using an anonymous self-administered questionnaire before and after the education intervention. Chi-square test was used to compare differences before and after the intervention. Non-conditional logistic regression analysis was used to identify the factors that affect HIV/AIDS knowledge. RESULTS: Misconceptions about basic medical knowledge and non-transmission modes of HIV/AIDS among all the students prevail. Approximately 10% to 40% of students had negative attitudes about HIV/AIDS before the intervention. After the intervention, all of the students had significant improvements in knowledge and attitude about HIV/AIDS (P<.05, indicating that educational intervention increased the students' knowledge significantly and changed their attitudes positively. Logistic regression analyses indicated that before the intervention the students' level of knowledge about HIV/AIDS was significantly associated with grade, economic status of the family, and attitudes toward participation in HIV/AIDS health information campaigns. CONCLUSIONS: HIV/AIDS education programs were welcomed by secondary students and positively influenced HIV/AIDS-related knowledge and attitudes. A systematic and long-term intervention among secondary school students must be

The study was a school-based intervention conducted in three middle schools and two high schools in Wuhan, China, which included 702 boys and 766 girls, with ages from 11 to 18 years old. The intervention was a one-class education program about HIV/AIDS for participants. HIV/AIDS knowledge, attitude, and high-risk behaviors were investigated using an anonymous self-administered questionnaire before and after the education intervention. Chi-square test was used to compare differences before and after the intervention. Non-conditional logistic regression analysis was used to identify the factors that affect HIV/AIDS knowledge. Misconceptions about basic medical knowledge and non-transmission modes of HIV/AIDS among all the students prevail. Approximately 10% to 40% of students had negative attitudes about HIV/AIDS before the intervention. After the intervention, all of the students had significant improvements in knowledge and attitude about HIV/AIDS (Peducational intervention increased the students' knowledge significantly and changed their attitudes positively. Logistic regression analyses indicated that before the intervention the students' level of knowledge about HIV/AIDS was significantly associated with grade, economic status of the family, and attitudes toward participation in HIV/AIDS health information campaigns. HIV/AIDS education programs were welcomed by secondary students and positively influenced HIV/AIDS-related knowledge and attitudes. A systematic and long-term intervention among secondary school students must be conducted for the prevention of HIV.

  9. Changing Occupational Roles in Audit Society—The Case of Swedish Student Aid Officials

    Full Text Available This article is about occupational change concerning a non-professional group of Street Level Bureaucrats—student aid officials at the Swedish Board for Study Support (SBSS. The aim is to describe and analyze changes in their occupational role—their discretional space and working conditions under the impact of changed ways to manage public service organizations and new information and communication technology. The SBSS is the sole administrator of student financial aid in Sweden. Its officials investigate and take decisions about students’ applications and repayment of loans. This work includes interacting with clients via telephone and computer. These officials have to have a certain amount of discretion to interpret and apply rules and regulations on specific circumstances in individual cases. How are their working conditions affected by organizational and policy changes in the authority? How is their ability to exercise influence and control over their own work performance affected? The analysis highlights how officials suffer from decreased discretion and an increasing routinization in their work. This is a result of a regulatory framework continuously growing in detail together with increasing management control based on new information and communication technology. What remains of discretion is a kind of ‘task’ discretion, the ability to do minor technical manipulations of rules in individual cases. Even today’s top management seems critical of this development. Besides further automatization and reduction of staff an ongoing process of organizational change is therefore also aiming to develop officials’ competence and working conditions toward what may be seen as organizational professionalism, a development of specific occupational skills and a discretion adjusted and subordinated to managerial means and ends. The analysis rests on data from a research project (2011 to 2014 about Institutional Talk. Data sources are

(6 An important factor in the spread of HIV/AIDS is believed to be poor knowledge about how it is spread and can be prevented. The utility of the Health Belief Model continues to be suggested in identifying preventive behaviors. This study is a cross- sectional study that 180 female students from three high schools in Yazd, Iran, completed a specially designed questionnaire, based on Health Belief Model in spring 2009. Our data showed that the mean score of perceived susceptibility was 21.19 (out of 32 and perceived severity was 12.47 (out of 24. Also the mean score of perceived benefits and barriers were 9.05 and 9.45 (out of 12 and out of 16 respectively.

    Full Text Available HIV and AIDS can result in visual impairment, therefore it is important that those who have or atrisk of contracting the disease have a basic knowledge of its ocular manifestations, so that they may seek eye care early. This study assessed the per-ceptions of a sample of senior high school students at the Capricorn district, Limpopo Province, South Africa about the ocular manifestations of HIV/AIDS and its management. Questionnaires were distributed to the students in their classrooms after school hours and upon completion were collected the same day. Data analysis revealed that 27.8% of the participants agreed that HIV/AIDS can affect the eyes. Another 27.8% responded that HIV/AIDS could cause dry eyes. Less than a third (31.4% indicated that the disease could cause red eyes, 31.5% and 38.1% respectively indicated that HIV/AIDS could cause cancer of the eyelids and the eyeball.  About half of the respondents (52% agreed that the disease could cause swollen eyelids; while about 46% agreed that vision loss or blindness could occur in HIV/AIDS.  Many (65.6% indicated that an ophthalmologist or an optometrist should be consulted for HIV/AIDS-related eye problems and only 16.5% reported that traditional healers could be consulted. Perception about the ocular manifestations of HIV and AIDS is poor among the participants, suggesting a need for awareness campaigns and education.  (S Afr Optom 2012 71(3 117-122

  3. Representations of SARS in the British newspapers.

    Science.gov (United States)

    Washer, Peter

    2004-12-01

    In the Spring of 2003, there was a huge interest in the global news media following the emergence of a new infectious disease: severe acute respiratory syndrome (SARS). This study examines how this novel disease threat was depicted in the UK newspapers, using social representations theory and in particular existing work on social representations of HIV/AIDS and Ebola to analyse the meanings of the epidemic. It investigates the way that SARS was presented as a dangerous threat to the UK public, whilst almost immediately the threat was said to be 'contained' using the mechanism of 'othering': SARS was said to be unlikely to personally affect the UK reader because the Chinese were so different to 'us'; so 'other'. In this sense, the SARS scare, despite the remarkable speed with which it was played out in the modern global news media, resonates with the meanings attributed to other epidemics of infectious diseases throughout history. Yet this study also highlights a number of differences in the social representations of SARS compared with earlier epidemics. In particular, this study examines the phenomena of 'emerging and re-emerging infectious diseases' over the past 30 or so years and suggests that these have impacted on the faith once widely held that Western biomedicine could 'conquer' infectious disease.

    Full Text Available Background: Peer education seeks to enroll students in persuasive communication programs aiming at AIDS prevention. Providing information about AIDS prevention methods can lead to behavioral change and also a potential reduction in unsafe sexual behavior, particularly among young people.Objective: This study aims to assess the role of peer education interventions in improving awareness, attitudes, and practices of secondary school students and peer educators towards AIDS.Methods: This is a pre-and post-study. The study was conducted among 400 students who were randomly selected from 10 gender-balanced schools. They received the information from trained peer educators. 200 peers carried out the intervention (20 peers from each school, which was conducted in phases. The intervention required coordinating with official concerned stakeholders, preparing teaching aids, and four days of training workshops for the peer educators. The data was analyzed using the Statistical Package for Social Science program (SPSS. A paired sample t-test was obtained and utilized to interpret the changes observed in pre- and post-intervention knowledge, attitude, and practice.Results: The study showed that the intervention program improved participants' knowledge from 75.5% to 83.2%. This improvement was with specific regard to the following: the causative agent of AIDs (p = 0.017, which improved from 77.7% to 81.5%; the spread of HIV through mosquitos (p = 0.001, which showed an increase from 12.7% to 23.8%; the program focused on the concept of the HIV carrier (p = 0.001, and also on the AIDS risk when having multiple sex partners, (p = 0.001, showing an increase of 47.5% to 83.5%.

    HIV Counselling and Testing (VCT) and knowledge about HIV are some key strategies in the prevention and control of HIV/AIDS in Ghana. However, HIV knowledge and utilization of VCT services among university students is low. The main objective was to determine the level of HIV/AIDS knowledge and to explore factors associated with the use HIV counselling and testing among private university students in Accra, Ghana. A cross-sectional study was conducted using structured questionnaires among 324 conveniently selected students enrolled at a privately owned tertiary institution in Accra, Ghana. The respondents consisted of 56.2% males and 43.8% females aged 17 - 37 years. The mean HIV/AIDS knowledge score of was 7.70. There was a significant difference in knowledge of HIV/AIDS by gender where female students had more knowledge about HIV/AIDS than males [t (322) = 2.40, p = 0.017]. The ANOVA results showed that there was a significant difference in HIV/AIDS knowledge according to the age groups [F (3, 321) = 6.26, p = 0. 0001] and marital status [F (3, 321) = 4.86, p = 0. 008] of the sample. Over half of the participants had not tested for HIV, although over 95% of them knew where to access counseling and testing services. The study also revealed a significant association between demographic variables, testing for HIV and intention to test in the future. Participants who were never married (single), aged 17 - 20 years and had knowledge of two routes of HIV transmission were more likely to have taken an HIV test. Males were more likely to take an HIV test in the future than females. Majority of the students receive HIV/AIDS information from both print and electronic media, but few of them received such information from parents. The students HIV knowledge was very good, yet HIV testing were low. Health education and HIV intervention programmes must not only provide accurate information, but must be made to help to equip private university students

    Full Text Available Abstract Background Until recently, young people in Kazakhstan have been only moderately affected by the global HIV epidemic. Today, however, the HIV epidemic in Central Asia is one of the most rapidly increasing epidemics in the world. It is mainly concentrated to vulnerable groups such as intravenous drug users, sex workers, the purchasers of sexual services and the financially marginalized. Young, sexually active people may however be the gateway for the epidemic to the general population, and knowledge about their attitudes and behavior is therefore important in planning preventive measures. Methods To gather information about young students and their attitudes and knowledge about HIV/AIDS, we collected 600 structured questionnaires and made 23 semi-structured interviews among three groups of students. Response rate was 99%. Results Almost 99% of the respondents had heard of HIV/AIDS, and 89% could identify ways to protect oneself against sexually transmitted HIV/AIDS. The main routes of transmission, sexual contact without condom and intravenous drug use, were both identified by 97% of the students. Twenty-five percent of the female students and 75% of the male students had had one or more sexual partners. More than 30% of the young men had purchased sex, and homosexuality was widely stigmatized. Conclusion Risks for the spread of HIV/AIDS among young people in Kazakhstan include prostitution as well as stigmatization of the HIV positive and of homosexuals. Protective factors are good knowledge about risks and protection, and opportunities to talk and gather information about sexuality and HIV/AIDS.

    Full Text Available Background and Purpose: Acquired Immunodeficiency Syndrome (AIDS is a great threat to the youth. The aim is to assess the knowledge of secondary technical schools students on AIDS, identify related misconceptions, and measure the effect of a short health education program on their level of knowledge. Materials and Methods: This quasi-experimental study was done on 575 secondary technical schools students in Assiut City, recruited through a two-stage stratified cluster sampling. A self-administered anonymous questionnaire was used to collect data. A health education program was implemented, and its effect assessed through pre-post testing. Results: The age range of the students was 16 to 20 years, with more girls (57.0%. Only 30.8% had satisfactory knowledge about AIDS in the pretest. Statistically significant improvements in knowledge were revealed after program implementation (P<0.001. Students who were Muslim, of urban residence, and had mobile phones had significantly higher scores (P=0.037, 0.004, 0.038 respectively. The most common misconceptions were the definition of AIDS according to transmission, and phobias related to transmission, which decreased after the intervention. Multivariate analysis showed that the statistically significant independent predictors of the change in knowledge score after the intervention were age, religion and the health education program. Conclusion: Secondary technical schools students in Assiut city have a major deficiency in knowledge and many misconceptions regarding AIDS. The educational intervention had a positive impact on their knowledge, but a less marked effect on misconceptions. Knowledge was affected by age and religious belief. It is recommended that more health educational efforts tailored to needs and with approaches suitable to community cultures and values be introduced.

    A structured questionnaire in English and Afrikaans was administered to 1471 randomly selected secondary school students from Katima Mulilo, Ondangwa, Windhoek, and Keetmanshoop educational regions of Namibia in a study to determine their cognitive, attitudinal, and behavioral risks which could promote HIV infection. The students were aged 13-28 years (mean age, 18 years). Approximately half were in grades 8, 9, and 10, while the remainder were in grades 11 and 12, and 47.8% of the students were male. 50% of the students were unaware of AIDS, 42% thought that some people were immune to AIDS, 48% reported that they would be rejected by their peers if they refused to have premarital sex, 47% indicated that mistrust was communicated when one used or suggested the use of a condom during sexual intercourse, and 50% believed that alcohol facilitates communication with peers of the opposite sex. The study found differences in the expression of AIDS-related risks due to age, sex, and region. Significantly more boys than girls and more students from Northern than from Central and Southern regions thought that mistrust was communicated by condom use and sexual intercourse made one popular, proved sexual maturity, showed commitment to and maintained love relationships. The theoretical and practical implications of these findings are discussed.

    To evaluate the feasibility and effectiveness of a life-planning skills training program using participatory methods among rural senior high school students in Shangcai County, Henan Province, China. The study was a quasi-experimental study conducted in three Shangcai County senior high schools with comparable socioculture-economic and demographic characteristics (two interventions and one control). The intervention, a life-planning skills program that uses participatory training methods, combining information education with effective skills building, was provided to all first-grade students (14-18 years old; 87% of them are between 15 and 17 years old) in the intervention group from October 2003 to December 2003. In total, 717 students from the intervention group, and 457 from the control enrolled at baseline, and over 91% of these were followed up at posttest. Group x time interaction effects in ordinal logistic regression analysis were found on HIV/AIDS-related knowledge (p .05). Three months of short-term HIV/AIDS education through life-planning skills training was welcomed by students and positively influenced HIV/AIDS-related knowledge, attitudes, protection self-efficacy, and communication among senior high school students in a rural area with high HIV prevalence.

    Objective African American young adults are disproportionately affected by the HIV/AIDS epidemic and often unaware of their personal risk for HIV. Historically black colleges and universities (HBCUs) enroll 25% of college-educated African American young adults and can play an important role in HIV prevention. We examined HIV/AIDS knowledge of students at HBCUs to inform and strengthen our HIV prevention efforts at HBCUs. Methods African American undergraduate HBCU students completed online surveys assessing HIV/AIDS knowledge and behaviors, and we analyzed data to assess their knowledge and behaviors. Results A total of 1,051 of 1,230 surveys completed (85.4%) were analyzable. Eighty-two percent of students had average/high HIV knowledge scores. Seventy-nine percent of students surveyed perceived themselves to be at low risk for HIV infection; 64% of those who had at least two or more sex partners had not used a condom at last sex encounter. In the final model, significant independent effects were identified for average/high knowledge of HIV risk, including agreeing with assessing a potential partner's HIV risk by all of the five actions listed (adjusted odds ratio [AOR] = 2.7, 95% confidence interval [CI] 1.7, 4.3) and never using a needle to inject drugs (AOR=5.6, 95% CI 3.2, 9.7). Conclusions Educating students about effectively assessing sex partner risk will improve HIV knowledge and prevention efforts at HBCUs. PMID:21886325

  15. SAR: Stroke Authorship Recognition

    KAUST Repository

    Shaheen, Sara

    2015-10-15

    Are simple strokes unique to the artist or designer who renders them? If so, can this idea be used to identify authorship or to classify artistic drawings? Also, could training methods be devised to develop particular styles? To answer these questions, we propose the Stroke Authorship Recognition (SAR) approach, a novel method that distinguishes the authorship of 2D digitized drawings. SAR converts a drawing into a histogram of stroke attributes that is discriminative of authorship. We provide extensive classification experiments on a large variety of data sets, which validate SAR\\'s ability to distinguish unique authorship of artists and designers. We also demonstrate the usefulness of SAR in several applications including the detection of fraudulent sketches, the training and monitoring of artists in learning a particular new style and the first quantitative way to measure the quality of automatic sketch synthesis tools. © 2015 The Eurographics Association and John Wiley & Sons Ltd.

    Full Text Available Introduction: Human immunodeficiency virus (HIV and acquired immune deficiency syndrome (AIDS is one of the most complex problems of health in the world. Since young population and mostly students are one of main groups at risk, this study was conducted to evaluate the effect of educational intervention on knowledge, attitude and performance of high school students about AIDS. Materials and Methods: This quasi-experimental study was conducted on 60 girls selected randomly from two public schools and they divided into two control and intervention groups. Research tool was a researcher-made questionnaire including two parts (demographic questions and specialized questions about AIDS. Firstly, a pretest was held, then 3 educational sessions were held on AIDS, its’ transmission and prevention ways by lecture, ask and answer, and educational pamphlet. Students took posttests immediately after educational intervention and two months later.

    Many studies have shown that in Africa, particularly in Togo, the 20- to 29-year-old age group is the age group most frequently affected by AIDS. This age group accounts for 84% of the students of the University of Benin. We studied students, most of the age group thought to be most at risk, investigating sexual behavior, knowledge and attitudes to AIDS and sexually transmitted diseases (STDs). The level of knowledge about the problems of AIDS and STDs was similar for both sexes and for all ages and levels of education of the students. Students had a reasonable knowledge of AIDS, particularly concerning the transmission of HIV (88.6% of students aware), risk behavior (80.8%), AIDS treatment (57.0%) and more general information about HIV (49.4%). They were poorly informed about the transmission (42.9%) and complications (0.69%) of other STDs. Most students had positive attitudes towards HIV issues, particularly the use of preventive measures (3.41 in 5) and the acceptance of infected individuals (3.98 in 5). However, few had seriously considered that AIDS and STDs might impact on their own sex lives (1. 84 in 5) and some were even fatalistic concerning HIV infection. The students were highly sexually active, having intercourse a mean of 31 times per year. Their sexual behavior depended on age and sex. The 15- to 19-year-olds preferred occasional partners. They had sexual intercourse 1 to 3 times per month and used condoms 10 to 20% of the time. The 20- to 29-year-olds had multiple partners. They had sexual intercourse 3 to 5 times per month and used condoms more than 30% of the time. Students over the age of 30 had many partners in addition to their regular partner. They had sexual intercourse 5 to 10 times per month and used condoms 0 to 20% of the time. Significantly more women than men had high-risk sexual behavior (40. 5% of men claimed to regularly use condoms, versus only 22.7% of the women and 11.9% of the women accepted anal penetration versus only 8. 4% of

    Full Text Available Objective: First aid is the helping behavior and initial care provided for an acute illness or injury. Students have the potential for changing the health scenario of the society if properly groomed and educated. The objective of the study is to evaluate the effectiveness of educational intervention on the first aid among middle school students of a rural school in West Bengal. Materials and Methods: A total of 230, 6th and 7th standard students were given a self-administered questionnaire for assessing their baseline knowledge about management of common injuries followed by educational intervention with a systematically devised teaching module during February to March 2016. Post intervention evaluation of their knowledge acquisition was done after 2 weeks with same questionnaire. Results: The baseline knowledge on the management of selected injuries was found to be insufficient among the study subjects. Paired t-test was performed to compare the pre- and post-test scores of knowledge and attitude of the students about first aid, and there was a significant change in knowledge from pretest score (mean = 1.50, standard deviation [SD] =0.47 to posttest score (mean = 6.53, SD = 1.30. To quantify the effectiveness of health education, effect size (Cohen's d was derived. For knowledge score, Cohen's d was 5.14 with large effect size indicating highly effective impact of the training program. Significant change was also noticed regarding attitude regarding first aid as evident from increase in pretest score (mean = 1.19, SD = 0.96 to posttest score (mean = 3.17, SD = 1.03; Cohen's d was 1.88 with medium effect size. Conclusion: Inculcating first-aid training in the school curriculum can be a fruitful investment in ensuring proper and timely management of illnesses and injuries not only for the school children but also for the community at large.

    Full Text Available This study examines the knowledge of HIV/AIDS, attitudes towards risky sexual behaviour and perceived behavioural control among students in Botswana. Data were collected from 445 students randomly selected from the University of Botswana and Boitekanelo College. Hundred and seventy three males and 272 females participated in the study. The study established that although more than 90% of students correctly identified routes of HIV transmission, misconceptions regarding HIV/AIDS still exist. This includes the belief that people can be infected with HIV because of witchcraft and that only people who have sex with gay or homosexual partners can be infected with HIV. Majority of students were aware of various sexual risks. However, the percentage of students who indicated that “it is difficult to ask my partner to use a condom” was still relatively high (13.5% based on the assumption that students are supposed to know the consequences of sexual risky behaviour. It was also found that male students were 3.48 times more likely to negotiate sex than their female counterparts (OR = 3.48, 95% CI: 1.09 − 11.13 and students who were 18 years and below were more likely to negotiate sex than students above 18 years of age (OR = 2.78, 95% CI: 1.42 − 18.32. Christians are four times less likely to negotiate sex compared to non-Christians (OR = 0.219, 95% CI: 0.095 − 0.506. More than 80% of students were comfortable discussing HIV or sex and sexuality with their friends, boyfriends/girlfriends or partners but uncomfortable discussing the same issues with their parents.

    @@ IntroductionCurrently, there are at least 850,000 people living with human immuno-deficiency virus (HIV) and acquired immuno-deficiency syndrome (AIDS) in China. Among them 16-29 years old account for about 65%. According to the Chinese health authorities, if the preventive measures are not effective, the figure could reach as many as 10 million by the year 2010[1]. Since there are currently no cure or vaccines for HIV/AIDS, changing people's high-risk behaviors is the main approach that is taken to slow down the epidemic. This can be done through effective HIV/AIDS education, especially for young people. In 1997, a 4-year adolescent HIV/AIDS peer education program was introduced to in Beijing and Shanghai, which was based on a successful Australian model developed by Professor Roger Short, in which senior medical students were trained and used as peer educators to teach their junior peers about HIV/AIDS[2].

    This study describes Finnish university students' knowledge and attitudes towards HIV and AIDS, homosexuality and sexual risk behaviour. Finnish-speaking students were randomly selected from all registered students at two universities in Finland (N = 9715, n = 950). The data were collected by using a modified version of the State University of New York at Buffalo School of Nursing AIDS Study Questionnaire on sexual risk behaviour developed by Held and Chng. The total response rate was 35% (n = 333). The data were analysed using quantitative statistical methods. Normally distributed data were analysed by t-test and one-way ANOVA, with Bonferroni corrections. Non-normally distributed data were analysed using the Mann-Whitney U-test and Kruskal-Wallis test, followed by a post-hoc test. The majority of students were familiar with HIV and AIDS, including its mode of transmission. However, there were still some misconceptions concerning HIV and AIDS. The oldest students and women had a more positive attitude towards people living with HIV and AIDS (PLWHA). Of patients with HIV or AIDS, intravenous drug users were perceived most negatively. Male students had more homophobic attitudes. Students who reported that religion had an important role in their lives had significantly stricter attitudes towards sexual risk behaviour. Students' knowledge correlated positively with general attitudes towards HIV and AIDS. Knowledge about HIV and AIDS will lead to more positive attitudes towards HIV and AIDS as a disease, towards those infected as well as homosexual people. There is a need to focus on preventive health care and sexual health promotion by educating young people and changing their attitudes towards sexual risk behaviour.

    Malaysia is confronted with an increasing incidence of HIV and AIDS among adolescents and young adults. The effectiveness of various programs offered to school going teenagers is unknown. The objective of this study is to measure the effectiveness of two hours talk on sex education offered by a non governmental organization (NGO) in improving youngsters' knowledge and perception towards HIV and AIDS. A cross sectional study was conducted among the adolescent students from a secondary school in Ipoh, Perak, a province of Malaysia. A total of 182 students participated in the study. A standard questionnaire consisting of demographic data, knowledge and perception towards HIV/ADIS were distributed before (pre-test) and after the intervention (post-test). Performance of participants was compared to establish the effectiveness of the intervention. Our findings suggests that there was a significant increase in participants' knowledge and perception after the intervention (p = 0.000). Knowledge improvement was found in both genders however, improvement in perception was higher among female students. Interestingly, 80% of participants disagree that sexual education will encourage sex among youngsters. NGOs are playing a supplementary role in providing sex education programs in schools. This program although of short duration but it is effective in enhancing adolescence awareness about HIV/AIDS.

    Service learning is one way that academia can contribute to assuring the public's health. The University of North Carolina's Team Epi-Aid service-learning program started in 2003. Since then, 145 graduate student volunteers have contributed 4,275 hours working with the state and local health departments during 57 activities, including outbreak investigations, community health assessments, and emergency preparedness and response. Survey data from student participants and public health partners indicates that the program is successful in meeting its goal of creating effective partnerships among the university, the North Carolina Center for Public Health Preparedness, and state and local health departments; supplying needed surge capacity to health departments; and providing students with applied public health experience and training. In this article, we discuss the programmatic lessons learned around administration, maintaining student interest, program sustainability, and challenges since program implementation.

    We evaluate the usefulness of X-band, airborne (helicopter) data for tomography over forestry regions and discuss the use of compressive sensing algorithms to aid X-band airborne tomography. This work examines if there is any information that can be gained from forest volumes when analysing forestry sites using X-band data. To do so, different forest scenarios were simulated and a fast SAR simulator was used to model airborne multipass SAR data, at X-band, with parameters based on Leonardo's PicoSAR instrument. Model simulations considered varying factors that affect the height determination when using tomography. The main parameters that are considered here are: motion errors of the platform, the spacing of the flight paths, the resolution of the SAR images and plant life being present under the canopy (an understory). It was found that residual motion errors from the airborne platform cause the largest error in the tomographic profile.

    The aim of the present cross-sectional study was to investigate the knowledge of undergraduate students and teachers at all physical education courses in the city of Belo Horizonte (Brazil) regarding first-aid measures to be taken following tooth avulsion as well as the need for the preventative use of mouth guards. The sample consisted of 442 individuals (Group 1: 53 teachers; Group 2: 389 undergraduate students). Data collection was carried out with the administration of a questionnaire with both objective and subjective questions addressing definitions, first-aid measures in cases of avulsion and tooth replantation, together with an assessment of the use and indication of mouth guards. Data analysis involved descriptive statistics and the chi-square test. The results revealed that 45.1% of the participants in both groups knew what a tooth replantation was. However, 91.6% judged themselves incapable of performing an immediate replantation. Among the overall sample, 45.9% has no knowledge on first-aid measures regarding tooth avulsion; sending the patient with an avulsed tooth to the dentist was the most often cited measure (42.3%). Immediate replantation was cited by 20.6% of the individuals in Group 1 and 5.9% of the individuals in Group 2 (P = 0.009). Regarding the storage medium, 17.1% of the individuals would keep the avulsed tooth in a dry medium. The majority of participants (58.3%) stated that the ideal extra-alveolar time for replantation was more than 360 min. Although 74% of the overall sample stated having knowledge of mouth guards, few reported making use or indicating the use of this piece of equipment. The present study revealed that the majority of teachers and undergraduate students of physical education courses do not have adequate knowledge regarding first-aid measures for tooth avulsion and do not use or indicate the use of mouth guards during sports activities.

    In spite of developed countries there are progressive trend about HIV/AIDS and its' aspects of transmission in the low socio-economic societies. The aim of this was to explain the youth's behavior in adopting HIV/AIDS related preventive behaviors in a sample of Iranian university students by emphasizing on fear appeals approaches alongside examining the role of self-control trait for explaining adoption on danger or fear control processes based on Extended Parallel Process Model (EPPM). A sample of 156 randomly selected university students in Jolfa, Iran was recruited in a predictive cross-sectional study by application of a researcher-designed questionnaire through self-report data collection manner. Sexual high risk behaviors, the EPPM variables, self-control trait, and general self-efficacy were measured as theoretical framework. Findings indicated that 31.3% of participants were in the fear control process versus 68.7% in danger control about HIV/AIDS and also the presence of multi-sex partners and amphetamine consumption amongst the participants. Low self-control trait and low perceived susceptibility significantly were related to having a history of multi-sex partners while high level of self-efficacy significantly increased the probability of condom use. Findings of the study were indicative of the protective role of high level of self-control, perceived susceptibility and self-efficacy factors on youth's high-risk behaviors and their preventative skills as well.

    The purpose of this article is to discuss the impact of the training program for predoctoral dental and hygiene students at Loma Linda University School of Dentistry (LLUSD) with regard to issues related to treating patients with a high risk of having HIV/AIDS. LLUSD offers a training program for fourth-year dental hygiene and predoctoral dental students that addresses the oral health care needs of persons with HIV disease. The training occurs in small groups 2 days per week at a community clinic serving HIV-positive individuals. Three academic quarters are required to train all fourth-year students each year. Evaluation of program effectiveness is conducted by means of pre- and post-session surveys. Dental hygiene and dental students completed the pre-survey during the spring quarter of their third year in public health dentistry courses. The same students completed the post-session survey at the end of their weekly training sessions during the fourth year. The overall change in all areas related to the students' comfort level in treating patients in the 3 defined categories is in a positive direction (p-valuedental hygiene students compared with predoctoral dental students. A comparison of pre- and post-session surveys reveals a significant improvement in students' perception of and comfort level with treating patients who are homosexual/bisexual or intravenous drug users, or who have a history of blood transfusion in both student groups upon completion of the HIV and the Dentist training program at LLUSD.

    We describe the findings from a survey assessing the beliefs regarding testing, confidentiality, disclosure, and environment of care and attitudes towards care of people with HIV/AIDS (PLHWA), in 1020, 4th and 5th year medical students, from public and private medical universities in Malaysia. A self-administered validated questionnaire based on the UNAIDS Model Questionnaire with a 5-point Likert scale (5, strongly disagree; 4, disagree; 3, neutral; 2, agree; 1, strongly agree) was used as a survey tool. The survey included demographic data and data on undergraduate training received on HIV/AIDS. Statistical significance in the demographic data and training received by respondents was evaluated using the chi-square test while the independent Student's t-test was used for comparison of means between public and private universities. A P value of <0.05 was considered statistically significant with 95% confidence interval. Our study revealed less than 20% of medical students received adequate training to care for PLHWA. They had prevalent negative beliefs regarding testing, confidentiality, disclosure and environment of care towards PLHWA although in giving care to PLHWA, their attitudes were largely positive and nondiscriminatory.

    Full Text Available The incidence of AIDS and other sexually transmitted diseases (STDs is increasing among adolescents. In order to better understand high-risk sexual behavior among students, a cross-sectional study based on a self-answered anonymous questionnaire was conducted in 10 public and private high schools in Rio de Janeiro, Brazil. Data were obtained on sociodemographics, knowledge of STD/AIDS, and sexual behavior. Among 945 students aged 13-21, 59% were sexually initiated, and the median age at first sexual intercourse was 15 years (range: 7-19. Although 94% reported being aware of the need for condom use for protection, only 34% informed always using condoms during sex. Low family income was associated with unsatisfactory knowledge (OR = 9.40; 95% CI = 6.05-14.60 and inconsistent condom use (OR = 11.60; 95% CI = 5.54-24.30. However, unsatisfactory knowledge was not associated with inconsistent condom use. School-based educational programs should focus on sexual behavior more than on transmission of knowledge, as well as targeting low-income students.

HIV prevalence statistics in most countries indicate that up to 60% of all new infections occur among 15 to 24 year olds, whilst this group also boasts the highest incidence of sexually transmitted infections (STIs. Statistical findings among South African students predict a 10% increase in the HIV infection rate, highlighting the inability of universities to cope with societies’ demands for academically trained workers which, in the near future, will have a detrimental effect on the economy of South Africa. From the literature it is evident that HIV/AIDS is more than a health issue, it is an inter-sectoral challenge to any society. This paper explored the interplay of gender and cultural factors on South African students’ sexual behaviour by inter alia discussing the following factors that might put students at risk for HIV infection: male dominance vs. female submissiveness; age of first sexual encounter; gender-based violence; contraception; circumcision; financial status; myths and ‘othering’; demonstrating the need for effective strategies, policies and programmes to protect young people, especially females from sexual abuse/rape and its consequences, including HIV. The literature review revealed that South African students, despite adequate HIV/AIDS knowledge, demonstrated high rates of sexual practices that place them at risk for HIV infection, i.e. unprotected sex, multiple partners and ‘sugar-daddy practices’. The paper concludes with a discussion on recommendations for future HIV prevention/ intervention programmes, highlighting the fact that it acquires an inclusive approach. Such interventions should move beyond the individual level to be effective and target gender-based inequalities, human rights violations, including sexual violence and rape, as well as stigma and poverty reduction, both at community and tertiary educational level.

    Recent observations and experimental evidence have purported that a virus causes SARS, but such viruses have been isolated in only less than half of SARS patients in some studies and virologist Vincent Plummer of Winnipeg's National Microbiology Laboratory found that indeed 1 in 5 perfectly healthy Canadians with a history of recent travel to Asia had the virus. Therefore SARS microbiologic origins remain unclear. Outbreaks of multi-drug resistant (MDR) tuberculosis and the atypical mycobacteria simulate SARS on clinical, radiologic, epidemiologic, and diagnostic laboratory grounds and it is only logical then to include them in the differential to find a definitive cause and cure for SARS.

    This article reviews a peer group Acquired Immunodeficiency Syndrome (AIDS) educational program at a university in Australia. Studies in the US have shown that most adolescents, although sexually active, do not believe they are likely to become infected with the Human Immunodeficiency Virus, and therefore do not attempt to modify their sexual behavior. A 1st step in educating students is to introduce them to condoms and impress upon them the fact that condoms should be used at the beginning of all sexual relationships, whether homosexual or heterosexual. In this program 3rd year medical students were targeted, as they are effective communicators and disseminators of information to the rest of the student body. After class members blow up condoms, giving them a chance to handle various brands and observe the varying degrees of strength, statistical evidence about the contraceptive failure rate of condoms (0.6-14.7 per 100 women-years) is discussed. Spermicides, such as nonoxynol-9 used in conjunction with condoms, are also discussed, as are condoms for women, packaging and marketing of condoms, including those made from latex and from the caecum of sheep, the latter condoms being of questionable effectiveness in preventing transmission of the virus. The care of terminal AIDS cases and current global and national statistics on AIDS are presented. The program also includes cash prizes for the best student essays on condom use, the distribution of condoms, condom key rings and T-shirts, and a student-run safe sex stand during orientation week. All of these activities are intended to involve students and attract the interest of the undergraduate community. Questionnaires administered to students at the end of the course revealed that the lectures were received favorably. Questionnaires administered to new medical and English students attending orientation week revealed that 72% of students thought the stand was a good idea and 81% and 83%, respectively found it

    Full Text Available This study examined how technology can help in assessing and teaching Chinese tones to foreign students who are not used to tonal languages. It was an attempt to show how we can use the PRAAT software to make learners of Chinese as a foreign language realize their tonal errors. The data used was collected from the students at the University of Zimbabwe studying Chinese and this was part of a continuous assessment for the students’ pronunciation of Chinese tones. This method which was used by teachers to assess students’ tones was found to be easy to follow such that students could also utilize it for their own pronunciation practice. We argued that the use of computer-aided assessment makes assessment of students’ tone acquisition lesser arbitrary than when the teacher merely gives comments based on his or her individual perception. This is because this assessment method gives PRAAT acoustic pictures which show the tone structures for each student; hence, both the student and the teacher can visualize the errors. Since PRAAT can provide a platform to compare the student’s pronunciation with that of the native speaker and at the same time can help the teacher to explain why student’s pronunciation is wrong, this paper concludes that PRAAT can be a useful tool in assessing and teaching Chinese tones.

    Typical synthetic aperture RADAR (SAR) imaging employs a co-located RADAR transmitter and receiver. Bistatic SAR imaging separates the transmitter and receiver locations. A bistatic SAR configuration allows for the transmitter and receiver(s) to be in a variety of geometric alignments. Sandia National Laboratories (SNL) / New Mexico proposed the deployment of a ground-based RADAR receiver. This RADAR receiver was coupled with the capability of digitizing and recording the signal collected. SNL proposed the possibility of creating an image of targets the illuminating SAR observes. This document describes the developed hardware, software, bistatic SAR configuration, and its deployment to test the concept of a ground-based bistatic SAR. In the proof-of-concept experiments herein, the RADAR transmitter will be a commercial SAR satellite and the RADAR receiver will be deployed at ground level, observing and capturing RADAR ground/targets illuminated by the satellite system.

    Full Text Available We describe the findings from a survey assessing the beliefs regarding testing, confidentiality, disclosure, and environment of care and attitudes towards care of people with HIV/AIDS (PLHWA, in 1020, 4th and 5th year medical students, from public and private medical universities in Malaysia. A self-administered validated questionnaire based on the UNAIDS Model Questionnaire with a 5-point Likert scale (5, strongly disagree; 4, disagree; 3, neutral; 2, agree; 1, strongly agree was used as a survey tool. The survey included demographic data and data on undergraduate training received on HIV/AIDS. Statistical significance in the demographic data and training received by respondents was evaluated using the chi-square test while the independent Student’s t-test was used for comparison of means between public and private universities. A value of <0.05 was considered statistically significant with 95% confidence interval. Our study revealed less than 20% of medical students received adequate training to care for PLHWA. They had prevalent negative beliefs regarding testing, confidentiality, disclosure and environment of care towards PLHWA although in giving care to PLHWA, their attitudes were largely positive and nondiscriminatory.

    2005-05-01

    The adaptive noise radar algorithm allows computation of compressed pseudo-pulses from a received noise radar signal at the receiver ADC rate. This is accomplished through use of LMS channel identification algorithms commonly exploited in wireless communications. This paper shows how having access to compressed pseudo-pulses at the ADC rate may be exploited to simultaneously implement SAR and GMTI modes in two parallel Doppler-processing chains. Simultaneous SAR and GMTI will aid in tracking of alternately moving and stationary targets.

    Synthetic Aperture Radar (SAR) is critical for remote sensing. It works day and night, in good weather or bad. Bistatic SAR is a new kind of SAR system, where the transmitter and receiver are placed on two separate platforms. Bistatic SAR is one of the most important trends in SAR development, as the technology renders SAR more flexible and safer when used in military environments. Imaging is one of the most difficult and important aspects of bistatic SAR data processing. Although traditional SAR signal processing is fully developed, bistatic SAR has a more complex system structure, so sign

    2007-10-01

    During flu season, respiratory infections can cause non-specific influenza-like-illnesses (ILIs) in up to one-half of the general population. If a future SARS outbreak were to coincide with flu season, it would become exceptionally difficult to distinguish SARS rapidly and accurately from other ILIs, given the non-specific clinical presentation of SARS and the current lack of a widely available, rapid, diagnostic test. We construct a deterministic compartmental model to examine the potential impact of preemptive mass influenza vaccination on SARS containment during a hypothetical SARS outbreak coinciding with a peak flu season. Our model was developed based upon the events of the 2003 SARS outbreak in Toronto, Canada. The relationship of different vaccination rates for influenza and the corresponding required quarantine rates for individuals who are exposed to SARS was analyzed and simulated under different assumptions. The study revealed that a campaign of mass influenza vaccination prior to the onset of flu season could aid the containment of a future SARS outbreak by decreasing the total number of persons with ILIs presenting to the health-care system, and consequently decreasing nosocomial transmission of SARS in persons under investigation for the disease.

  14. Cloaked similarity between HIV-1 and SARS-CoV suggests an anti-SARS strategy

    Directory of Open Access Journals (Sweden)

    2003-09-01

    Full Text Available Abstract Background Severe acute respiratory syndrome (SARS is a febrile respiratory illness. The disease has been etiologically linked to a novel coronavirus that has been named the SARS-associated coronavirus (SARS-CoV, whose genome was recently sequenced. Since it is a member of the Coronaviridae, its spike protein (S2 is believed to play a central role in viral entry by facilitating fusion between the viral and host cell membranes. The protein responsible for viral-induced membrane fusion of HIV-1 (gp41 differs in length, and has no sequence homology with S2. Results Sequence analysis reveals that the two viral proteins share the sequence motifs that construct their active conformation. These include (1 an N-terminal leucine/isoleucine zipper-like sequence, and (2 a C-terminal heptad repeat located upstream of (3 an aromatic residue-rich region juxtaposed to the (4 transmembrane segment. Conclusions This study points to a similar mode of action for the two viral proteins, suggesting that anti-viral strategy that targets the viral-induced membrane fusion step can be adopted from HIV-1 to SARS-CoV. Recently the FDA approved Enfuvirtide, a synthetic peptide corresponding to the C-terminal heptad repeat of HIV-1 gp41, as an anti-AIDS agent. Enfuvirtide and C34, another anti HIV-1 peptide, exert their inhibitory activity by binding to a leucine/isoleucine zipper-like sequence in gp41, thus inhibiting a conformational change of gp41 required for its activation. We suggest that peptides corresponding to the C-terminal heptad repeat of the S2 protein may serve as inhibitors for SARS-CoV entry.

    Although the prevalence of human immunodeficiency virus (HIV) decreased in the last decade worldwide, the number of deaths due to HIV/AIDS and communicable diseases including syphilis, hepatitis, and tuberculosis had dramatically increased in developing countries. Education and behavior are incredibly important factors to prevent these diseases' spread. This study highlights the range of differences in knowledge, attitude, and behavior of 434 sexually active medical students towards HIV/AIDS and sexually transmitted infections (STIs). Because the surveyed population constitutes the forefront of healthcare providers and was originated from different area of the world, this is the first time a study sought to investigate the behavioral attitude of this group of population irrespective of the three levels of their academic and professional knowledge. Several factors including sociodemographic characteristics, sexual behavior, HIV/AIDS, and STIs related patterns play a key role in medical student attitude and behavior towards people infected with HIV/AIDS and STIs. Our findings add consistent value in prior studies which aimed to stop new infections and also imply further investigations on the management of the studied infections by medical students. The present study arouses much interest among participants and provides evidence of reinforcing medical students' education on HIV/AIDS and STIs. PMID:27195287

    Although the prevalence of human immunodeficiency virus (HIV) decreased in the last decade worldwide, the number of deaths due to HIV/AIDS and communicable diseases including syphilis, hepatitis, and tuberculosis had dramatically increased in developing countries. Education and behavior are incredibly important factors to prevent these diseases' spread. This study highlights the range of differences in knowledge, attitude, and behavior of 434 sexually active medical students towards HIV/AIDS and sexually transmitted infections (STIs).

    Few investigators have studied nurses' or nursing students' responses to caring for AIDS patients. The purpose of this exploratory study was to test the Ajzen-Fishbein (1980) Theory of Reasoned Action in a student nurse population about AIDS patient care. This theory offers an approach to explaining individuals' intentions to engage in certain behaviors as determined by two components: attitudes toward the behavior and subjective norms. Forty-six second-year baccalaureate nursing students completed a questionnaire developed according to guidelines described by Ajzen and Fishbein (alpha reliability range was .69-.85) prior to and following an instructional unit on caring for AIDS patients. Consistent with the theory, students' attitudes and subjective norms were found to be significant predictors of intentions to care for AIDS patients in their clinical experience (R2 = .29, F[1, 43] = 6.63, p less than .003). In addition, qualitative data resembled those in previous reports of fear of contagion among health professionals. The effects of the instructional unit about caring for AIDS patients resulted in significant changes in both attitudes and subjective norms.

    BACKGROUND: SARS, as a kind of sudden stress source, make quite a few people present symptoms such as panic emotion, psychological allergic reaction, etc. There are also partial nurse students who worry about to be infected, fear to practice in clinical departments and live in an irritable mood, which interferes their clinical practice and affects both body and mind health.OBJECTIVE: Through the investigation of the nurse students' stress response and anxiety symptom to understand their psychological stress response scale and anxiety level during the prevailing period of SARS.DESIGN: An intersectional investigation with the nurse students doing clinical practice or probation apprentice as observative objects.SETTING: Department of Psychiatry, West China Hospital, Sichuan Univesity PARTICIPANTS: In May 2003, the nurse students of 2-4 grade doing clinical practice and probation in West China Nursing College of Sichuan University were selected as observative objects, all of whom had no record of mental illness or other severe disease, and volunteered to receive the investigation. 305 questionnaires were sent out and 299 valid questionnaires were taken back. They were 171 junior college students (47.2%) and 128undergraduates (42.8%) of 18-32 years old, average 21.51,and boy students held 4.6% while girl students 93.4%.METHODS: The crisis response questionnaire was used to investigate the nurse students' response scale to SARS crisis from three aspects such as cognition, emotion and behavior. The response grade is from 1 to 10.The total score scale is 3-30. 3 means no impairment, 3-9 means is a little impairment, 9-15 means slight impairment, 15-21 means moderate, 21-27 means significant, and more than 27 means severe. The self-rating anxiety scale (SAS) compiled by Zung in 1971 was mainly used to assess the frequency of the appearance of the symptoms defined in each item in the students being investigated, including 20 items and score in 4 grades: 1 indicates never

    Oral health care of patients with human immunodeficiency virus (HIV)/acquired immune-deficiency syndrome (AIDS) is a growing area of concern. Information on HIV- and AIDS-related knowledge among dental students provides a crucial foundation for efforts aimed at developing an appropriate dental curriculum on HIV and AIDS. The purpose of this study was to assess the knowledge and attitude of Indian clinical dental students towards the treatment of patients with HIV/AIDS and perceived sources of information regarding HIV-related issues. Data were collected from clinical dental students (third year, fourth year and internship) from three dental institutions in Delhi National Capital Region (NCR). The questions assessed the knowledge and attitude towards treatment of patients with HIV and the perceived source of information related to HIV. The willingness to treat HIV-positive patients among dental students was 67.0%, and 74.20% were confident of treating a patient with HIV/AIDS. The potential problems in rendering treatment to these patients were effect on the attitude of other patients (49.90%) and staff fears (52.50%). The correct knowledge regarding the infection-control practice (barrier technique) was found among only 15.50% of respondents. The respondents had sufficient knowledge regarding the oral manifestations of HIV/AIDS. There was no correlation between the knowledge and attitude score, demonstrating a gap between knowledge and attitude among dental students regarding treatment of HIV-infected patients. Appropriate knowledge has to be delivered through the dental education curriculum, which can instil confidence in students about their ability to manage HIV-positive patients. © 2014 FDI World Dental Federation.

    Wetlands are transition zones where the flow of water, the nutrient cycling, and the sun energy meet to produce a unique and very productive ecosystem. They provide critical habitat for a wide variety of plant and animal species, including the larval stages of many ocean fish. Wetlands also have a valuable economical importance, as they filter nutrients and pollutants from fresh water used by human and provide aquatic habitats for outdoor recreation, tourism, and fishing. Globally, many such regions are under severe environmental stress, mainly from urban development, pollution, and rising sea level. However, there is increasing recognition of the importance of these habitats, and mitigation and restoration activities have begun in a few regions. A key element in wetlands conservation, management, and restoration involves monitoring its hydrologic system, as the entire ecosystem depends on its water supply. Heretofore, hydrologic monitoring of wetlands are conducted by stage (water level) stations, which provide good temporal resolution, but suffer from poor spatial resolution, as stage station are typically distributed several, or even tens of kilometers, from one another. Wetland application of InSAR provides the needed high spatial resolution hydrological observations, complementing the high temporal resolution terrestrial observations. Although conventional wisdom suggests that interferometry does not work in vegetated areas, several studies have shown that both L- and C-band interferograms with short acquisition intervals (1-105 days) can maintain excellent coherence over wetlands. In this study we explore the usage of InSAR for detecting water level changes in various wetland environments around the world, including the Everglades (south Florida), Louisiana Coast (southern US), Chesapeake Bay (eastern US), Pantanal (Brazil), Okavango Delta (Botswana), and Lena Delta (Siberia). Our main study area is the Everglades wetland (south Florida), which is covered by

    The prevention of HIV and AIDS, especially amongst young people, is very important, as they are the future leaders. South Africa carries a high burden of the HIV and AIDS disease, and efforts at the prevention of the disease need to be intensified. University students are also at risk, and prevention efforts need to be intensified to ensure that students graduate and enter the world of work to become productive citizens. Failure to pay attention to preventative behaviour amongst university students may have negative socio-economic consequences for the country. The paper presents a quantitative study undertaken amongst students at the University of South Africa, an Open and Distance Learning Institution in South Africa. The aim of the study was to explore the perceptions of students regarding life skills as a behaviour change strategy at Unisa. The study was conducted in the three regions of the University: Midlands region, Gautengregion and Limpopo region. Data were collected by means of self-administered questionnaires and were analysed by using the Statistical Programme for Social Sciences. The findings revealed that students have a need to attend life skills workshops, which are facilitated by trained student counsellors since they believe that the life skills training will assist them to be assertive and practise behaviours which will not make them vulnerable to the HIV and AIDS infection.

    Full Text Available Abstract Background The objective of this study was to test the hypothesis that personality preference, which can be related to learning style, influences individual utilization of CAI applications developed specifically for the undergraduate medical curriculum. Methods Personality preferences of students were obtained using the Myers-Briggs Type Indicator (MBTI test. CAI utilization for individual students was collected from entry logs for two different web-based applications (a discussion forum and a tutorial used in the basic science course on human anatomy. Individual login data were sorted by personality preference and the data statistically analyzed by 2-way mixed ANOVA and correlation. Results There was a wide discrepancy in the level and pattern of student use of both CAI. Although individual use of both CAI was positively correlated irrespective of MBTI preference, students with a "Sensing" preference tended to use both CAI applications more than the "iNtuitives". Differences in the level of use of these CAI applications (i.e., higher use of discussion forum vs. a tutorial were also found for the "Perceiving/Judging" dimension. Conclusion We conclude that personality/learning preferences of individual students influence their use of CAI in the medical curriculum.

    Full Text Available Abstract Background HIV/AIDS related stigma interferes with the provision of appropriate care and support for people living with HIV/AIDS. Currently, programs to address the stigma approach it as if it occurs in isolation, separate from the co-stigmas related to the various modes of disease transmission including injection drug use (IDU and commercial sex (CS. In order to develop better programs to address HIV/AIDS related stigma, the inter-relationship (or 'layering' between HIV/AIDS stigma and the co-stigmas needs to be better understood. This paper describes an experimental study for disentangling the layering of HIV/AIDS related stigmas. Methods The study used a factorial survey design. 352 medical students from Guangzhou were presented with four random vignettes each describing a hypothetical male. The vignettes were identical except for the presence of a disease diagnosis (AIDS, leukaemia, or no disease and a co-characteristic (IDU, CS, commercial blood donation (CBD, blood transfusion or no co-characteristic. After reading each vignette, participants completed a measure of social distance that assessed the level of stigmatising attitudes. Results Bivariate and multivariable analyses revealed statistically significant levels of stigma associated with AIDS, IDU, CS and CBD. The layering of stigma was explored using a recently developed technique. Strong interactions between the stigmas of AIDS and the co-characteristics were also found. AIDS was significantly less stigmatising than IDU or CS. Critically, the stigma of AIDS in combination with either the stigmas of IDU or CS was significantly less than the stigma of IDU alone or CS alone. Conclusion The findings pose several surprising challenges to conventional beliefs about HIV/AIDS related stigma and stigma interventions that have focused exclusively on the disease stigma. Contrary to the belief that having a co-stigma would add to the intensity of stigma attached to people with HIV/AIDS

    2013-12-01

    To demonstrate the feasibility of orbital remote sensing for global ocean observations, NASA launched Seasat on June 27th, 1978. Being the first space borne SAR mission, Seasat produced the most detailed SAR images of Earth from space ever seen to that point in time. While much of the data collected in the USA was processed optically, a mere 150 scenes had been digitally processed by March 1980. In fact, only an estimated 3% of Seasat data was ever digitally processed. Thus, for over three decades, the majority of the SAR data from this historic mission has been dormant, virtually unavailable to scientists in the 21st century. Over the last year, researchers at the Alaska Satellite Facility (ASF) Distributed Active Archive Center (DAAC) have processed the Seasat SAR archives into imagery products. A telemetry decoding system was created and the data were filtered into readily processable signal files. Due to nearly 35 years of bit rot, the bit error rate (BER) for the ASF DAAC Seasat archives was on the order of 1 out of 100 to 1 out of 100,000. This extremely high BER initially seemed to make much of the data undecodable - because the minor frame numbers are just 7 bits and no range line numbers exist in the telemetry even the 'simple' tasks of tracking the minor frame number or locating the start of each range line proved difficult. Eventually, using 5 frame numbers in sequence and a handful of heuristics, the data were successfully decoded into full range lines. Concurrently, all metadata were stored into external files. Recovery of this metadata was also problematic, the BER making the information highly suspect and, initially at least, unusable in any sort of automated fashion. Because of the BER, all of the single bit metadata fields proved unreliable. Even fields that should be constant for a data take (e.g. receiving station, day of the year) showed high variability, each requiring a median filter to be usable. The most challenging, however, were the

    Buldeo, Priya; Gilbert, Leah

    2015-01-01

    The Health Belief Model (HBM) is a psychosocial framework that attempts to explain health behaviour. It is determined by an individual's personal beliefs or perceptions about a disease and the options available to decrease its occurrence. In the context of sexual risk behaviours, literature reveals that knowledge about HIV/AIDS and Voluntary Counselling and Testing (VCT) are key strategies in the management and prevention of HIV. This study was conducted in 2011, the same year the First Things First campaign was implemented in universities across South Africa to maximise opportunities for HIV testing among youth. It aimed to identify first-year students' responses to HIV/AIDS and VCT at the University of the Witwatersrand (WITS). The mixed research methods consisted of self-administered structured questionnaires with a sample population of 195 first-year students and 2 in-depth interviews with experts in the field of HIV/AIDS. Descriptive statistical analyses (frequencies and cross-tabulations) and thematic content analysis was carried out. The findings indicate that students are willing to know their status. The positive influence of peers is a motivation for those accessing VCT. However, some students do not access VCT due to personal fears while other students do not access VCT because of their low individual risk perception for HIV due to sexual abstinence. It concludes that university students' self-efficacy and cues to action might bring about a positive change in the future of the epidemic within a university context.

    This paper provides analytical principles to relate the signature of a moving target to parameters in a SAR system. Our objective is to establish analytical tools that could predict the shift and smearing of a moving target in a subaperture SAR image. Hence, a user could identify the system parameters such as the coherent processing interval for a subaperture that is suitable to localize the signature of a moving target for detection, tracking and geolocating the moving target. The paper begins by outlining two well-known SAR data collection methods to detect moving targets. One uses a scanning beam in the azimuth domain with a relatively high PRF to separate the moving targets and the stationary background (clutter); this is also known as Doppler Beam Sharpening. The other scheme uses two receivers along the track to null the clutter and, thus, provide GMTI. We also present results on implementing our SAR-GMTI analytical principles for the anticipated shift and smearing of a moving target in a simulated code. The code would provide a tool for the user to change the SAR system and moving target parameters, and predict the properties of a moving target signature in a subaperture SAR image for a scene that is composed of both stationary and moving targets. Hence, the SAR simulation and imaging code could be used to demonstrate the validity and accuracy of the above analytical principles to predict the properties of a moving target signature in a subaperture SAR image.

    A survey of the level of public awareness of AIDS in India was conducted on 600 men and women from Aligarth town, 180 km east of Delhi, and in Srinagar City in Kashmir Valley. Subjects were chosen from illiterate and below matriculate level; matriculate to graduate level; and graduate and above. Subjects were asked if they had heard of a disease called AIDS, when they first hears about AIDS, what was their 1st source of information, what are the reasons behind the incidence of AIDS and whether they are scared of AIDS. None of the illiterate group had heard of AIDS. 24% of the men and 14% of the women in the matriculate and graduate level group (clerks, mechanics, primary school teachers, businessmen and undergraduate students) had heard of AIDS. 92% of the highest educated group (lawyers, engineers, school principals and university students or teachers) had heard of AIDS. The 8% who had not were mostly women. Most of the highly educated, but fewer of the middle group were afraid of AIDS, but most thought AIDS would not spread in India because "our life pattern is different." None was aware that AIDS can spread from unchecked blood transfusions and re-use of unsterilized needles in hospitals. The most common information sources were newspapers, radio, magazines and friends. Most had not heard of AIDS from doctors or other health workers, or from television, which could be an extremely effective medium to reach people.

    Full Text Available Abstract Background The first case of HIV in Ethiopia was reported in 1984. Since then, HIV/AIDS has become a major public health concern in the country, leading the Government of Ethiopia to declare a public health emergency in 2002. Although the epidemic is currently stable, HIV/AIDS remains a major development challenge for Ethiopia. The spread of HIV in any community is in part determined by the knowledge of attitude towards sexuality of its members and by their actual sexual practices. The aim of the study was to assess students' knowledge, attitudes and practices regarding HIV/AIDS and STDs in Gondar, North West Ethiopia. Methods A cross sectional study was conducted between February 1 to March 1, 2009 in preparatory high school students. Pre-tested questioner was used to generate the data and analysis was made by SPSS version 15. Chi -square value was calculated and p-value Results All the students had heard about AIDS before the interview. Knowledge on some aspect of the disease was quite low in the study group. Only half of the students knew that at present, AIDs is incurable and that HIV infection can be acquired through sexual contact with a 'familiar' person. Knowledge about STI was also quite low, 39% knew that pus in the urine is a symptom of STI and 45.4% knew that acquisition of other STIs is increases the chance of HIV transmission following unsafe sex with known cases. 25% of the study group had previous sexual intercourse and exposed at least one risk behavior. About 34% of the respondents had negative attitude towards AIDS and STDs. Conclusion Awareness about STDs and methods of prevention of HIV and STDs was low. More risk behavior was observed in male and those with alcohol and drugs of abuse.

    2014-10-01

    While typical SAR imaging employs a co-located (monostatic) RADAR transmitter and receiver, bistatic SAR imaging separates the transmitter and receiver locations. The transmitter and receiver geometry determines if the scattered signal is back scatter, forward scatter, or side scatter. The monostatic SAR image is backscatter. Therefore, depending on the transmitter/receiver collection geometry, the captured imagery may be quite different that that sensed at the monostatic SAR. This document presents imagery and image products formed from captured signals during the validation stage of the bistatic SAR research. Image quality and image characteristics are discussed first. Then image products such as two-color multi-view (2CMV) and coherent change detection (CCD) are presented.

    Beijing has been severely affected by SARS, and SARS-associated coronavirus has been confirmed as its cause. However, clinical and experimental evidence implicates the possibility of co-infection. In this report, reovirus was isolated from throat swabs of SARS patients, including the first case in Beijing andher mother. Identification with the electron microscopy revealed the characteristic features of reovirus. 24 of 38 samples from other SARS cases were found to have serologic responses to the reovirus. Primers designed for reovirus have amplified several fragments of DNA, one of which was sequenced (S2 gene fragment), which indicates it as a unique reovirus (orthoreovirus). Preliminary animal experiment showed that inoculation of the reovirus in mice caused death with atypical pneumonia. Nevertheless, the association of reovirus with SARS outbreak requires to be further investigated.

    The application of Synthetic Aperture Radar (SAR) techniques to classical radar altimetry offers the potential for greatly improved Earth surface mapping. This paper provides an overview of the progress of SAMOSA, Development of SAR Altimetry Studies and Applications over Ocean, Coastal zones and Inland waters, an on-going ESA-funded project. The main objective of SAMOSA is to better quantify the improvement of SAR altimetry over conventional altimetry on water surfaces. More specifically, one of the tasks focuses on the reduction of SAR mode data to pulse-limited altimeter data, and a theoretical modelling to characterize the expected gain between high Pulse Repetition Frequency (PRF) reduced SAR mode data and low PRF classical Low-Resolution Mode (LRM) data. To this end, theoretical modelling using the Cramer-Rao bound (CRB) will be used and the results will be compared to previous theoretical estimates [7], using an analysis akin to that in [8].

  14. Visiting Holocaust-Related Sites with Medical Students as an Aid in Teaching Medical Ethics.

    González-López, Esteban; Ríos-Cortés, Rosa

    2016-05-01

    During the Nazi period numerous doctors and nurses played a nefarious role. In Germany they were responsible for the sterilization and killing of disabled persons. Furthermore, the Nazi doctors used concentration camp inmates as guinea pigs in medical experiments for military or racial purposes. A study of the collaboration of doctors with National Socialism exemplifies behavior that must be avoided. Combining medical teaching with lessons from the Holocaust could be a way to transmit Medical Ethics to doctors, nurses and students. The authors describe a study tour with medical students to Poland, to the largest Nazi extermination camp, Auschwitz, and to the city of Krakow. The tour is the final component of a formal course entitled: "The Holocaust, a Reflection from Medicine" at the Autónoma University of Madrid, Spain. Visiting sites related to the Holocaust, the killing centers and the sites where medical experiments were conducted has a singular meaning for medical students. Tolerance, non-discrimination, and the value of human life can be both learnt and taught at the very place where such values were utterly absent.

    This study was a follow-up to a previous study that was done among first semester nursing college students at a historically Black college and university in northeastern United States. The original intent was to ascertain their perceptions and knowledge of various aspects of the Human Immunodeficiency Virus/Acquired Immune Deficiency Syndrome (HIV/AIDS) phenomenon. It involved an anonymous survey questionnaire featuring yes and no answers, a Likert scale, and qualitative response questions concerning prevention behavior. Respondents were asked whether HIV/AIDS could make an individual "sick enough to die", whether they thought that wearing a condom would diminish their feeling during the sexual experience, and whether they would insist their partners use a condom. The original study consisted of 68 students. The follow-up study,four years later, consisted of the 20 remaining nursing students from the original cohort and was undertaken with the intent to appraise their knowledge level and to ascertain whether their attitudes towards the use of condoms as a way to prevent HIV/AIDS and STDs had changed. Findings from this follow-up study indicated that educational attainment of the respondents did not translate into a change in attitudes about responsible sexual behavior. Further findings may suggest that intensive HIV/AIDS education begin at an earlier phase in a students'education. Along with the basics of HIV/AIDS education, students need to learn to be respectful of each others' health and wellbeing. It is essential that a nurturing and protective environment exist so that young women are not afraid of the consequences related to asking partners to wear condoms during sexual encounters.

    Currently, research in sexual behavior and awareness in female Chinese college students (FCCSs) is limited, particularly regarding the difference and the influencing factors between students from rural areas and urban areas. To fill the gap in available data, a cross-sectional study using anonymous questionnaires was conducted among 3193 female students from six universities located in Beijing, Shanghai, and Guangzhou, China, from February to June, 2013. Of the 2669 respondents, 20.6% and 20.9% of the students from urban and rural areas, respectively, reported being sexually experienced. The proportion of students who received safe-sex education prior to entering university from rural areas (22.4%, 134/598) was lower (P Sexual behavior has become increasingly common among FCCSs, including high-risk sexual behavior such as unprotected commercial sex. However, knowledge concerning human immunodeficiency virus (HIV)/acquired immune deficiency syndrome (AIDS) transmission and the risks is insufficient, particularly for those from rural areas, which is a challenge for HIV/AIDS control in China. The Chinese government should establish more specific HIV/AIDS prevention policies for Chinese young women, strengthen sex education, and continue to perform relevant research.

    A principal measure of Synthetic Aperture Radar (SAR) image quality is the manifestation in the SAR image of a spatial impulse, that is, the SAR's Impulse Response (IPR). IPR requirements direct certain design decisions in a SAR. Anomalies in the IPR can point to specific anomalous behavior in the radar's hardware and/or software.

    Employees and students at the Faculty of Dentistry, University of Oslo responded to a comprehensive questionnaire regarding knowledge and attitudes towards human immunodeficiency virus (HIV). The intention of the present study was to describe possible relationships between the two. The questionnaire consisted of 39 closed questions. The response rate was 75% (436/584). The answers were used to construct additive indices for knowledge and attitudes. The knowledge index reflected the number of correct answers concerning risk groups and transmission. A factor analysis revealed three dimensions of attitudes ('legal', 'personal risk', and 'personal consequences'), which were analysed separately against knowledge. Correlation analyses (Spearman r) of all respondents together (n = 436) revealed a weak, but statistically significant, positive correlation between knowledge and the 'legal' and 'personal risk' dimension of attitudes (r = 0.16, P 0.05). The strongest correlation was found between knowledge and the 'legal' dimension (r = 0.43, P risk' dimension (r = 0.41, P patients with HIV/acquired immune deficiency syndrome were identified amongst the respondents. A weak correlation between knowledge and two of the attitudes might indicate that knowledge plays a role in this respect.

    It has been reported that lactoferrin (LF) participates in the host immune response against Severe Acute Respiratory Syndrome Coronavirus (SARS-CoV) invasion by enhancing NK cell activity and stimulating neutrophil aggregation and adhesion. We further investigated the role of LF in the entry of SARS pseudovirus into HEK293E/ACE2-Myc cells. Our results reveal that LF inhibits SARS pseudovirus infection in a dose-dependent manner. Further analysis suggested that LF was able to block the binding of spike protein to host cells at 4°C, indicating that LF exerted its inhibitory function at the viral attachment stage. However, LF did not disrupt the interaction of spike protein with angiotensin-converting enzyme 2 (ACE2), the functional receptor of SARS-CoV. Previous studies have shown that LF colocalizes with the widely distributed cell-surface heparan sulfate proteoglycans (HSPGs). Our experiments have also confirmed this conclusion. Treatment of the cells with heparinase or exogenous heparin prevented binding of spike protein to host cells and inhibited SARS pseudovirus infection, demonstrating that HSPGs provide the binding sites for SARS-CoV invasion at the early attachment phase. Taken together, our results suggest that, in addition to ACE2, HSPGs are essential cell-surface molecules involved in SARS-CoV cell entry. LF may play a protective role in host defense against SARS-CoV infection through binding to HSPGs and blocking the preliminary interaction between SARS-CoV and host cells. Our findings may provide further understanding of SARS-CoV pathogenesis and aid in treatment of this deadly disease. PMID:21887302

    The TerraSAR-X is a German national SAR- satellite system for scientific and commercial applications. It is the continuation of the scientifically and technologically successful radar missions X-SAR (1994) and SRTM (2000) and will bring the national technology developments DESA and TOPAS into operational use. The space segment of TerraSAR-X is an advanced high-resolution X-Band radar satellite. The system design is based on a sound market analysis performed by Infoterra. The TerraSAR-X features an advanced high-resolution X-Band Synthetic Aperture Radar based on the active phased array technology which allows the operation in Spotlight-, Stripmap- and ScanSAR Mode with various polarizations. It combines the ability to acquire high resolution images for detailed analysis as well as wide swath images for overview applications. In addition, experimental modes like the Dual Receive Antenna Mode allow for full-polarimetric imaging as well as along track interferometry, i.e. moving target identification. The Ground Segment is optimized for flexible response to (scientific and commercial) User requests and fast image product turn-around times. The TerraSAR-X mission will serve two main goals. The first goal is to provide the strongly supportive scientific community with multi-mode X-Band SAR data. The broad spectrum of scientific application areas include Hydrology, Geology, Climatology, Oceanography, Environmental Monitoring and Disaster Monitoring as well as Cartography (DEM Generation) and Interferometry. The second goal is the establishment of a commercial EO-market in Europe which is driven by Infoterra. The commercial goal is the development of a sustainable EO-business so that the e.g. follow-on systems can be completely financed by industry from the profit. Due to its commercial potential, the TerraSAR-X project will be implemented based on a public-private partnership with the Astrium GmbH. This paper will describe first the mission objectives as well as the

In order to better understand high-risk sexual behavior among students, a cross-sectional study based on a self-answered anonymous questionnaire was conducted in 10 public and private high schools in Rio de Janeiro, Brazil. Data were obtained on sociodemographics, knowledge of STD/AIDS, and sexual behavior. Among 945 students aged 13-21, 59% were sexually initiated, and the median age at first sexual intercourse was 15 years (range: 7-19. Although 94% reported being aware of the need for condom use for protection, only 34% informed always using condoms during sex. Low family income was associated with unsatisfactory knowledge (OR = 9.40; 95% CI = 6.05-14.60 and inconsistent condom use (OR = 11.60; 95% CI = 5.54-24.30.

    Full Text Available Background: Education sector plays an important role in imparting vital information regarding HIV AIDS to large number of adolescents. The present study was carried out to assess the baseline level of knowledge and attitude regarding HIV / AIDS and retention of various aspects of information over the period of one year among ninth standard school students in Mumbai. Methods and Material: The present study was designed as a school based interventional follow up study. Health education sessions on HIV/AIDS were conducted. Pre test, immediate post test, along with a follow up post test at six months and one year were administered. SPSS (Version 16 and Excel software were used for statistical analysis. Z tests for difference between proportions were applied. Results: The proportion of correct responses regarding some of the aspects of knowledge of HIV / AIDS significantly increased on health education intervention. However, no significant change in the proportion of correct responses regarding blood donation leading to HIV transmission was observed. Significant waning (p < 0.01 away of the effect of health education has been observed in some important aspects especially regarding spread without being aware of transmission, involvement of infected needles, condoms as mode of prevention and no complete cure till date. Though there is a general acceptance of HIV positive patients, attitudes involving sexual mode of transmission, drug abuse and homosexuality did not show positive change post intervention. Conclusions: Health education sessions were very effective in increasing knowledge. However, students tend to lose information regarding certain aspects. We thus need strategies for reinforcing knowledge as well as attitude aspect in school AIDS education.

    Accurate clinical diagnosis of severe acute respiratory syndrome (SARS) based on the current World Health Organization definition is difficult and at times impossible at the early stage of the disease. Both false positive and false negative cases are commonly encountered and this could have far-reaching detrimental effects on the patients, their family and the clinicians alike. Contact history is particularly important in diagnosing SARS in children as their presenting features are often non-specific. The difficulty in making a correct diagnosis is further compounded by the lack of a sensitive rapid diagnostic test. Serology is not particularly helpful in the initial triaging of patients as it takes at least 3 weeks to become positive. Co-infection and other treatable conditions should not be missed and conventional antibiotics should remain as part of the first-line treatment regimen. We report five cases to illustrate the difficulties and dilemmas faced by clinicians in diagnosing SARS in children.

    Severe acute respiratory syndrome (SARS) emerged in 2002 as a severe and highly contagious infectious disease that rapidly spread to a number of different countries. The collaborative efforts of the global scientific community have provided, within a short period of time, substantial insights into the molecular biology and immunology of SARS-CoV. Although the outbreak has been contained, there is continuous concern that the virus may resurface into the human population through seasonal changes, animal reservoirs or laboratory accidents. The severe morbidity and mortality associated with SARS make it imperative that an effective vaccine be developed to prevent reemergence and epidemics in the future.

    Full Text Available Abstract Introduction: The social stigma in people with HIV/AIDS by students and health professionals hinders early diagnosis, timely treatment and increases the spread risk of the pandemic. Objective: To describe the social stigma in the care of people with HIV/AIDS by socioeconomic, demographic and academic conditions. Materials and methods: A cross-sectional study in 1,253 individuals. The scale of social stigma was validated with criteria of appearance, content, construct, internal consistency, reliability and usefulness. The analyzes included Pearson correlations, Cronbach,factor analysis, frequencies, summary measures, Mann Whitney U, Anova and multivariate linear regression in SPSS 21.0 R. Results: The highest frequencies for stigma were related to the differential treatment delivered to people with HIV/AIDS (57.2 %, accounting necessary to create exclusive hospitals for this group (52.5 %, the attention of these patients increases the risk of infection (49.7 %, and the need to isolate HIV-positive (43.3 %. The main predictors of social stigma were the academic program, performing the presumptive test and semester of study. Conclusion: Social stigma attitudes were higher in individuals of the first cycle of formation, without performing the test screening, and medical students; this corroborates the need to improve communication, information and health education strategies to combat stigma.

    One of the most pervasive stigmatising conditions in society today is HIV/AIDS. In Trinidad and Tobago, stigma and discrimination are still pervasive especially against persons living with HIV/AIDS (PLHIV) and at-risk groups. HIV stigmatisation takes place at all levels including health care institutions, and is a major obstacle to effective HIV/AIDS prevention and care. This study examined health care students' reactions towards HIV patients. A stratified random sample of 339 health care students from Trinidad was used. A 2 × 2 factorial design using vignettes manipulated a male patient's sexual orientation (heterosexual/homosexual) and HIV onset controllability (high/low). Multivariate analysis of variance and discriminant function analysis were used to analyse the data. There was a significant main effect of HIV onset controllability on participants' attribution of blame, emotions, prejudicial evaluation and willingness to interact with PLHIV, Λ (.64) F(6, 330) = 31.44, p <.001, [Formula: see text] = .37. Attribution of blame and prejudicial evaluation discriminated between reactions to patients in low onset control and high onset control vignettes. Cognitive-affective appraisal processes are instrumental in determining health care providers' reaction towards PLHIV.

    This study explores the potential of Synthetic Aperture Radar (SAR) to aid Unmanned Aerial Vehicle (UAV) navigation when Inertial Navigation System (INS) measurements are not accurate enough to eliminate drifts from a planned trajectory. This problem can affect medium-altitude long-endurance (MALE) UAV class, which permits heavy and wide payloads (as required by SAR) and flights for thousands of kilometres accumulating large drifts. The basic idea is to infer position and attitude of an aerial platform by inspecting both amplitude and phase of SAR images acquired onboard. For the amplitude-based approach, the system navigation corrections are obtained by matching the actual coordinates of ground landmarks with those automatically extracted from the SAR image. When the use of SAR amplitude is unfeasible, the phase content can be exploited through SAR interferometry by using a reference Digital Terrain Model (DTM). A feasibility analysis was carried out to derive system requirements by exploring both radiometric and geometric parameters of the acquisition setting. We showed that MALE UAV, specific commercial navigation sensors and SAR systems, typical landmark position accuracy and classes, and available DTMs lead to estimated UAV coordinates with errors bounded within ±12 m, thus making feasible the proposed SAR-based backup system.

    This study aims to assess the attitudes, knowledge, preparedness, and willingness of dentists and dental students to treat people-living-with-HIV/AIDS (PLWHA) in China, and to determine the factors associated with willingness to treat. We surveyed dentists and dental students in hospitals and dental schools in five regions in China with varying PLWHA prevalence. Survey questions covered demographics, as well as four categories regarding treating PLWHA: knowledge (scaled 0-1), attitude (scaled 1-4), preparedness (scaled 1-4), and willingness to treat (scaled 1-4). Composite scores for each category were calculated as weighted means. Confounder-adjusted regression analysis was performed to determine the factor(s) correlated with willingness to treat. We collected 394 (84 percent) and 462 (90 percent) useable surveys from dentists and dental students respectively. Dentists' mean composite scores were 0.63 (poor knowledge), 2.1 (negative attitude), 2.8 (adequate preparedness), and 2.5 (neutral willingness). Students' mean composite scores were 0.64 (poor knowledge), 2.3 (negative attitude), 2.7 (adequate preparedness), and 2.6 (positive willingness). Forty-five percent of dentists and 59 percent of dental students had scores indicating positive willingness to treat. Attitude was the only factor consistently correlated with willingness to treat. Dentists and dental students scored low in all categories except for preparedness. It is imperative that knowledge of HIV/AIDS and attitudes toward PLWHA be further improved during dental training to increase the access to and effectiveness of dental care of PLWHA in China and to enhance their quality of life. © 2016 American Association of Public Health Dentistry.

    Severe acute respiratory syndrome (SARS) and avian influenza are two important newly emerged infections with pandemic potential. Both infections have crossed the species barrier to infect humans. SARS originated from southern China and spread to many countries in early 2003. The close collaboration of scientists around the world resulted in a rapid identification of the causative agent, and the early isolation of infected cases and meticulous infection control measures were the key to successfully controlling the outbreak of SARS. The first outbreak of human cases of avian influenza was reported in 1997 in Hong Kong. Since 2003, there have been many small outbreaks of human cases around the world, and the reported mortality is greater than 50%. Current evidence suggests that the human-to-human transmission of avian influenza is rather inefficient, but mutation might occur in the future resulting in improved transmission and possibly a pandemic in humans. As with the outbreak of SARS, the development of sensitive and accurate early diagnostic tests is extremely important for successful control of the outbreak at source. The availability of isolation facilities, the stockpiling of antiviral agents and effective and safe vaccination will be extremely important in minimising the damage of a new influenza pandemic.

    2017-02-01

    Computerized ionospheric tomography (CIT) based on spaceborne synthetic aperture radar (SAR) is an emerging technique to construct the three-dimensional (3-D) image of ionosphere. The current studies are all based on the Low Earth Orbit synthetic aperture radar (LEO SAR) which is limited by long repeat period and small coverage. In this paper, a novel ionospheric 3-D CIT technique based on geosynchronous SAR (GEO SAR) is put forward. First, several influences of complex atmospheric environment on GEO SAR focusing are detailedly analyzed, including background ionosphere and multiple scattering effects (induced by turbulent ionosphere), tropospheric effects, and random noises. Then the corresponding GEO SAR signal model is constructed with consideration of the temporal-variant background ionosphere within the GEO SAR long integration time (typically 100 s to 1000 s level). Concurrently, an accurate total electron content (TEC) retrieval method based on GEO SAR data is put forward through subband division in range and subaperture division in azimuth, obtaining variant TEC value with respect to the azimuth time. The processing steps of GEO SAR CIT are given and discussed. Owing to the short repeat period and large coverage area, GEO SAR CIT has potentials of covering the specific space continuously and completely and resultantly has excellent real-time performance. Finally, the TEC retrieval and GEO SAR CIT construction are performed by employing a numerical study based on the meteorological data. The feasibility and correctness of the proposed methods are verified.

    SARS is a new kind of pneumonia. From the end of 2002 to the beginning of 2003, SARS broke in Guangdong province, Hong Kong and Beijing, and then gradually spread to the world. SARS is extremely contagious. The symptoms of SARS progress very quickly. SARS smashes the people's tranquil life and many people live in horror, worry and anxiety. But if we review the medical history of pneumonia, we would have a better understanding of SARS. This article focuses the history of people's understanding of pneumonia on the historical documents, diagnosis, etiology and treatment. Through the epidemic of SARS, the author hopes to express that contagion will live with us for a long time, but it is not a deadly disease. It is preventable and good care is essential for contagious patients. As Chinese people, we should have the best use of TCM in our combat with contagion.

  15. Refocusing vibrating targets in SAR images

    In synthetic-aperture radar (SAR) returned signals, ground-target vibrations introduce a phase modulation that is linearly proportional to the vibration displacement. Such modulation, termed the micro-Doppler effect, introduces ghost targets along the azimuth direction in reconstructed SAR images that prevents SAR from forming focused images of the vibrating targets. Recently, a discrete fractional Fourier transform (DFrFT) based method was developed to estimate the vibration frequencies and instantaneous vibration accelerations of the vibrating targets from SAR returned signals. In this paper, a demodulation-based algorithm is proposed to reconstruct focused SAR images of vibrating targets by exploiting the estimation results of the DFrFT-based vibration estimation method. For a single-component harmonic vibration, the history of the vibration displacement is first estimated from the estimated vibration frequency and the instantaneous vibration accelerations. Then a reference signal whose phase is modulated by the estimated vibration displacement with a delay of 180 degree is constructed. After that, the SAR phase history from the vibration target is multiplied by the reference signal and the vibration-induced phase modulation is canceled. Finally, the SAR image containing the re-focused vibration target is obtained by applying the 2-D Fourier transform to the demodulated SAR phase history. This algorithm is applied to simulated SAR data and successfully reconstructs the SAR image containing the re-focused vibrating target.

    Fish, W.; McKillip, M.; Li, S.

    2003-12-01

    Advances in electronic resources allow more realistic student problems, increased student engagement and self learning, and the use of interactive, exploratory learning. We are using a sophisticated yet easy-to-use groundwater modeling and visualization program (Interactive Groundwater, IGW, Li and Liu: www.egr.msu.edu/ ˜lishug/research/igw) to build packages of innovative tools for instructors and students. Equipped with an advanced graphical interface, IGW allows interactive visualization and manipulation of complex, multidimensional subsurface systems including hydrology, contaminant transport and assessment of contaminated sites. Two principle product packages are the Graphical Teaching Aid (GTA) and the Student Learning Exercise (SLE), developed as part of the NSF-supported Virtual Interactive Remediation in the Groundwater Environment (VIRGE). A GTA is a classroom-presentation guide that includes text materials for the instructor as well as supporting electronic IGW files for interactive graphical demonstrations and discussions in the classroom. Text files include a conceptual outline and a list of principles to be examined in the lecture as well as a flexible script punctuated and illustrated throughout by use of IGW as a highly interactive "electronic chalkboard". The thorough text guides the instructor in the effective use of IGW, suggests ideas to engage student interaction, and provides ways to tailor the interactive presentation to student needs. An SLE complements the GTA as an interactive exercise to engage students in discovery learning. As with GTAs, SLEs are designed for specific levels of classes (undergraduate or graduate) and specific populations (non-technical, science, or engineering majors). Text files (background and instruction) and IGW files (for problem visualization, interactive manipulation and solution) are provided. The SLEs include interactive computer-based exercises ranging from introductory investigations to extensive, open

    2010-01-01

    The purpose of this study was to determine if a computer-aided instruction learning module improves students' knowledge of the neuroanatomy/physiology and clinical examination of the dorsal column-medial lemniscal (DCML) system. Sixty-one physical therapy students enrolled in a clinical neurology course in entry-level PT educational programs at two universities participated in the study. Students from University-1 (U1;) had not had a previous neuroanatomy course, while students from University-2 (U2;) had taken a neuroanatomy course in the previous semester. Before and after working with the learning module, students took a paper-and-pencil test on the neuroanatomy/physiology and clinical examination of the DCML system. Kruskal-Wallis one-way ANOVA and Mann-Whitney tests were used to determine if differences existed between neuroanatomy/physiology examination scores and clinical examination scores before and after taking the learning module, and between student groups based on university attended. For students from U1, neuroanatomy/physiology post-test scores improved significantly over pre-test scores (p Neuroanatomy/physiology pre-test scores from U2 were significantly better than those from U1 (p < 0.001); there was no significant difference in post-test scores (p = 0.062). Clinical examination pre-test and post-test scores from U2 were significantly better than those from U1 (p < 0.001). Clinical examination post-test scores improved significantly from the pre-test scores for both U1 (p < 0.001) and U2 (p < 0.001).

    felt that the vignettes made it easier to develop empathy for the patients rather than reading about them. The use of virtual communities, for example, NZ Pharmville, show promise as a platform to aid in teaching and learning. The resources in NZ Pharmville allow students ongoing access to patient video clips that attempt to depict a real life situation, and enable students to engage with the fictional characters. The virtual community provided an educational experience which was well received by students. This teaching method appeared to promote active patient-centered learning and allowed students to reflect on and revisit these skills on a weekly basis.

  3. Study on Geosynchronous Circular SAR

    2015-06-01

    Full Text Available The concept of Geosynchronous Circular SAR (Geo-CSAR is introduced in this paper. With the design of the geosynchronous orbit parameters, a near-circular satellite sub-track could be formed to enable the staring imaging mode, which supports the advanced applications for wide-field and 3-D information acquisition under long-term consistent observation. This paper also analyzes Geo-CSAR's imaging formation capabilities, and concludes its attractive advantages over low-earth orbit spaceborne SAR in terms of instantaneous coverage, consistent observing area, 3-D positioning accuracy and etc.. Encouraging expectations for Geo-CSAR thus could be positively predicted in military investigation and disaster monitoring management applications.

    2008-01-01

    Synthetic Aperture Radar (SAR) performance testing and estimation is facilitated by observing the system response to known target scene elements. Trihedral corner reflectors and other canonical targets play an important role because their Radar Cross Section (RCS) can be calculated analytically. However, reflector orientation and the proximity of the ground and mounting structures can significantly impact the accuracy and precision with which measurements can be made. These issues are examined in this report.

    Complex pixel values for Synthetic Aperture Radar (SAR) images of uniform distributed clutter can be represented as either real/imaginary (also known as I/Q) values, or as Magnitude/Phase values. Generally, these component values are integers with limited number of bits. For clutter energy well below full-scale, Magnitude/Phase offers lower quantization noise than I/Q representation. Further improvement can be had with companding of the Magnitude value.

  7. Spaceborne SAR Imaging Algorithm for Coherence Optimized.

    Directory of Open Access Journals (Sweden)

    Zhiwei Qiu

    Full Text Available This paper proposes SAR imaging algorithm with largest coherence based on the existing SAR imaging algorithm. The basic idea of SAR imaging algorithm in imaging processing is that output signal can have maximum signal-to-noise ratio (SNR by using the optimal imaging parameters. Traditional imaging algorithm can acquire the best focusing effect, but would bring the decoherence phenomenon in subsequent interference process. Algorithm proposed in this paper is that SAR echo adopts consistent imaging parameters in focusing processing. Although the SNR of the output signal is reduced slightly, their coherence is ensured greatly, and finally the interferogram with high quality is obtained. In this paper, two scenes of Envisat ASAR data in Zhangbei are employed to conduct experiment for this algorithm. Compared with the interferogram from the traditional algorithm, the results show that this algorithm is more suitable for SAR interferometry (InSAR research and application.

    Full Text Available According to the limitations of single channel Frequency Modulation Continuous Wave (FMCW Synthetic Aperture Radar (SAR, Digital Beamforming (DBF technology is introduced to improve system performance. Combined with multiple receive apertures, DBF FMCW SAR can obtain high resolution in low pulse repetition frequency, which can increase the processing gain and decrease the sampling frequency. The received signal model of DBF FMCW SAR is derived. The continuous antenna motion which is the main characteristic of FMCW SAR received signal is taken into account in the whole signal processing. The detailed imaging diagram of DBF FMCW SAR is given. A reference system is also demonstrated in the paper by comparing with a single channel FMCW SAR. The validity of the presented diagram is demonstrated with a point target simulation results.

    Current techniques for building detection in Synthetic Aperture Radar (SAR) imagery can be computationally expensive and/or enforce stringent requirements for data acquisition. The desire is to present a technique that is effective and efficient at determining an approximate building location. This approximate location can be used to extract a portion of the SAR image to then perform a more robust detection. The proposed technique assumes that for the desired image, bright lines and shadows, SAR artifact effects, are approximately labeled. These labels are enhanced and utilized to locate buildings, only if the related bright lines and shadows can be grouped. In order to find which of the bright lines and shadows are related, all of the bright lines are connected to all of the shadows. This allows the problem to be solved from a connected graph viewpoint. Where the nodes are the bright lines and shadows and the arcs are the connections between bright lines and shadows. Constraints based on angle of depression and the relationship between connected bright lines and shadows are applied to remove unrelated arcs. Once the related bright lines and shadows are grouped, their locations are combined to provide an approximate building location. Experimental results are provided showing the outcome of the technique.

    This paper presents a step towards a better interpretation of the scattering mechanism of different objects and their deformation histories in SAR interferometry (InSAR). The proposed technique traces individual SAR scatterer in high resolution optical images where their geometries, materials, and other properties can be better analyzed and classified. And hence scatterers of a same object can be analyzed in group, which brings us to a new level of InSAR deformation monitoring.

  11. Satellite SAR geocoding with refined RPC model

    Science.gov (United States)

    Zhang, Lu; Balz, Timo; Liao, Mingsheng

    2012-04-01

    Recent studies have proved that the Rational Polynomial Camera (RPC) model is able to act as a reliable replacement of the rigorous Range-Doppler (RD) model for the geometric processing of satellite SAR datasets. But its capability in absolute geolocation of SAR images has not been evaluated quantitatively. Therefore, in this article the problems of error analysis and refinement of SAR RPC model are primarily investigated to improve the absolute accuracy of SAR geolocation. Range propagation delay and azimuth timing error are identified as two major error sources for SAR geolocation. An approach based on SAR image simulation and real-to-simulated image matching is developed to estimate and correct these two errors. Afterwards a refined RPC model can be built from the error-corrected RD model and then used in satellite SAR geocoding. Three experiments with different settings are designed and conducted to comprehensively evaluate the accuracies of SAR geolocation with both ordinary and refined RPC models. All the experimental results demonstrate that with RPC model refinement the absolute location accuracies of geocoded SAR images can be improved significantly, particularly in Easting direction. In another experiment the computation efficiencies of SAR geocoding with both RD and RPC models are compared quantitatively. The results show that by using the RPC model such efficiency can be remarkably improved by at least 16 times. In addition the problem of DEM data selection for SAR image simulation in RPC model refinement is studied by a comparative experiment. The results reveal that the best choice should be using the proper DEM datasets of spatial resolution comparable to that of the SAR images.

    Access to oral health care for vulnerable populations is one of the concerns addressed by the U.S. Health Resources and Services Administration HIV/AIDS Bureau's Community-Based Dental Partnership Program (CBDPP). The program introduces dental students and residents at several dental schools to care for vulnerable patients through didactic and clinical work in community-based dental settings. This study of the dental students and residents in this program answered three questions: 1) What are their HIV knowledge, attitudes, and behaviors? 2) How has participation in the CBDPP impacted their knowledge, attitudes, and behaviors? 3) Has the intervention affected their work placement decisions and attitudes after graduation, particularly with respect to treating people living with HIV and other underserved populations? A total of 305 first- through fourth-year dental students and first- and second-year residents at five dental schools across the United States completed surveys before and after a community-based rotation and following graduation. Response rates at each of the five schools ranged from 82.4 to 100 percent. The results showed an increase in the participants' knowledge and positive attitudes regarding treatment for patients with HIV and other vulnerable populations post-rotation compared to pre-rotation. Results after graduation found that most respondents were practicing in private settings or in academic institutions as residents but were willing to treat a diverse patient population. These findings support the role of training programs, such as the CBDPP, for expanding the dental workforce to treating vulnerable populations including people living with HIV/AIDS.

    BIANYong; ZHOUYinqing; LIChunsheng

    2004-01-01

    In this paper, we establish the squint mode hybrid SAR (Synthetic aperture radar) geometry. Based on the squint mode SAR geometry, the hybrid SAR signal model in squint case is derived. Based on this signal model, the hybrid SAR imaging process parameter is discussed. Aimed at the squint case, we analyze not only the relationship between the resolution and SAR system parameters, but also the relation between the time extension of the maximum azimuth signal and SAR system parameters. This research establishes the theoretical foundation for the design of squint hybrid SAR and serves as a good guide for the future work of improving the resolution of squint hybrid SAR. Based on the two-step algorithm, by considering the squint angle and cubic phase term, we are going to use the deramp SC-Chirp Scaling algorithm for squint hybrid SAR imaging. This algorithm uses the deramp method for the first step processing, and the SC-Chirp Scaling algorithm for the second step processing. The process procedure of this algorithm includes the squint angle, has the explicit physical meaning, therefore is convenient for analysis. The computer simulation result proves the validity of the analysis.

    The Synthetic Aperture Radar (SAR) has viewed, in the last two years, a huge increment of interest from many preset and potential users. The good spatial resolution associated to the all weather capability lead to considering SAR not only a scientific instrument but a tool for verifying and controlling the daily human relationships with the Earth Environment. New missions were identified for SAR as spatial resolution became lower than three meters: disasters, pollution, ships traffic, volcanic eruptions, earthquake effect are only a few of the possible objects which can be effectively detected, controlled and monitored by SAR mounted on satellites. High resolution radar design constraints and dimensioning are discussed.

    This paper discusses reconstruction of three-dimensional surfaces from multiple bistatic synthetic aperture radar (SAR) images. Techniques for surface reconstruction from multiple monostatic SAR images already exist, including interferometric processing and stereo SAR. We generalize these methods to obtain algorithms for bistatic interferometric SAR and bistatic stereo SAR. We also propose a framework for predicting the performance of our multistatic stereo SAR algorithm, and, from this framework, we suggest a metric for use in planning strategic deployment of multistatic assets.

    2004-01-01

    The overarching goal of the InfoTerra/TerraSAR Initiative is to establish a self-sustaining operational/commercial business built on Europe"s know-how and experience in space-borne Synthetic Aperture Radar (SAR) technology, in SAR data processing as well as in SAR applications. InfoTerra stands for a new business concept based on supplying innovative geo-information products and services. TerraSAR is a space and ground system conceived to consist of an initial deployment and operation of 2 Radar satellites (one in X- and one in L-band) flying in a tandem configuration in the same orbit. The design of TerraSAR is driven by the market and is user-oriented. TerraSAR is key to capturing a significant proportion of the existing market and to opening new market opportunities, when it becomes operational. The InfoTerra/TerraSAR Initiative has evolved gradually. It started in 1997 as a joint venture between German (DSS) and British (MMS-UK) space industry, strongly supported by both space agencies, DLR and BNSC. In early 2001, DLR and BNSC submitted to ESA the Formal Programme Proposal for InfoTerra/TerraSAR to become an essential element of ESA"s Earth Watch Programme. In summer 2001, when it became evident that there was not yet sufficient support from the ESA Member States to allow immediate start entering into TerraSAR Phase C/D, it has been decided to implement first a TerraSAR consolidation phase. In early 2002, in order to avoid further delays, a contract was signed between DLR and Astrium GmbH on the development of one component of TerraSAR, the TerraSAR-X, in the frame of a national programme, governed by a Public Private Partnership Agreement. Even if now the different launch dates for TerraSAR-X and TerraSAR-L are narrowing down the window of common data acquisition, it is a reasonable starting point, but it should always be kept in mind that the utmost goal for the longterm is to achieve self sustainability by supplying geo-information products and services

    Full Text Available Arjun SinghDepartment of Pathology, Sri Venkateshwara Medical College Hospital and Research Centre, Pondicherry, IndiaPurpose: We use different methods to train our undergraduates. The patient-oriented problem-solving (POPS system is an innovative teaching–learning method that imparts knowledge, enhances intrinsic motivation, promotes self learning, encourages clinical reasoning, and develops long-lasting memory. The aim of this study was to develop POPS in teaching pathology, assess its effectiveness, and assess students’ preference for POPS over didactic lectures.Method: One hundred fifty second-year MBBS students were divided into two groups: A and B. Group A was taught by POPS while group B was taught by traditional lectures. Pre- and post-test numerical scores of both groups were evaluated and compared. Students then completed a self-structured feedback questionnaire for analysis.Results: The mean (SD difference in pre- and post-test scores of groups A and B was 15.98 (3.18 and 7.79 (2.52, respectively. The significance of the difference between scores of group A and group B teaching methods was 16.62 (P < 0.0001, as determined by the z-test. Improvement in post-test performance of group A was significantly greater than of group B, demonstrating the effectiveness of POPS. Students responded that POPS facilitates self-learning, helps in understanding topics, creates interest, and is a scientific approach to teaching. Feedback response on POPS was strong in 57.52% of students, moderate in 35.67%, and negative in only 6.81%, showing that 93.19% students favored POPS over simple lectures.Conclusion: It is not feasible to enforce the PBL method of teaching throughout the entire curriculum; However, POPS can be incorporated along with audiovisual aids to break the monotony of dialectic lectures and as alternative to PBL.Keywords: medical education, problem-solving exercise, problem-based learning

    Single and multi-frequency antenna concepts were developed to evaluate the feasibility of building large aperture polarimetric synthetic aperture radar (SAR) systems to be launched in low cost vehicles such as the Delta 2. The antennas are 18.9 m long by 2.6 m wide (L-band) and achieve single polarization imaging to an incidence angle of 55 degrees and dual/quad imaging to 42 degrees. When combined with strawman spacecraft designs, both concepts meet the mass and volume constraints imposed by a Delta 2 launch.

    Huxtable, Barton D.; Jackson, Christopher R.; Skaron, Steve A.

    1998-09-01

    Synthetic aperture radar (SAR) is uniquely suited to help solve the Search and Rescue problem since it can be utilized either day or night and through both dense fog or thick cloud cover. Other papers in this session, and in this session in 1997, describe the various SAR image processing algorithms that are being developed and evaluated within the Search and Rescue Program. All of these approaches to using SAR data require substantial amounts of digital signal processing: for the SAR image formation, and possibly for the subsequent image processing. In recognition of the demanding processing that will be required for an operational Search and Rescue Data Processing System (SARDPS), NASA/Goddard Space Flight Center and NASA/Stennis Space Center are conducting a technology demonstration utilizing SHARC multi-chip modules from Boeing to perform SAR image formation processing.

    Sanders, Toby; Gelb, Anne; Platte, Rodrigo B.

    2017-06-01

    This paper investigates accurate and efficient ℓ1 regularization methods for generating synthetic aperture radar (SAR) images. Although ℓ1 regularization algorithms are already employed in SAR imaging, practical and efficient implementation in terms of real time imaging remain a challenge. Here we demonstrate that fast numerical operators can be used to robustly implement ℓ1 regularization methods that are as or more efficient than traditional approaches such as back projection, while providing superior image quality. In particular, we develop a sequential joint sparsity model for composite SAR imaging which naturally combines the joint sparsity methodology with composite SAR. Our technique, which can be implemented using standard, fractional, or higher order total variation regularization, is able to reduce the effects of speckle and other noisy artifacts with little additional computational cost. Finally we show that generalizing total variation regularization to non-integer and higher orders provides improved flexibility and robustness for SAR imaging.

    2006-09-01

    Full Text Available BACKGROUND: The SARS outbreak of 2002-2003 presented clinicians with a new, life-threatening disease for which they had no experience in treating and no research on the effectiveness of treatment options. The World Health Organization (WHO expert panel on SARS treatment requested a systematic review and comprehensive summary of treatments used for SARS-infected patients in order to guide future treatment and identify priorities for research. METHODS AND FINDINGS: In response to the WHO request we conducted a systematic review of the published literature on ribavirin, corticosteroids, lopinavir and ritonavir (LPV/r, type I interferon (IFN, intravenous immunoglobulin (IVIG, and SARS convalescent plasma from both in vitro studies and in SARS patients. We also searched for clinical trial evidence of treatment for acute respiratory distress syndrome. Sources of data were the literature databases MEDLINE, EMBASE, BIOSIS, and the Cochrane Central Register of Controlled Trials (CENTRAL up to February 2005. Data from publications were extracted and evidence within studies was classified using predefined criteria. In total, 54 SARS treatment studies, 15 in vitro studies, and three acute respiratory distress syndrome studies met our inclusion criteria. Within in vitro studies, ribavirin, lopinavir, and type I IFN showed inhibition of SARS-CoV in tissue culture. In SARS-infected patient reports on ribavirin, 26 studies were classified as inconclusive, and four showed possible harm. Seven studies of convalescent plasma or IVIG, three of IFN type I, and two of LPV/r were inconclusive. In 29 studies of steroid use, 25 were inconclusive and four were classified as causing possible harm. CONCLUSIONS: Despite an extensive literature reporting on SARS treatments, it was not possible to determine whether treatments benefited patients during the SARS outbreak. Some may have been harmful. Clinical trials should be designed to validate a standard protocol for dosage

    The Phased Array type L-band Synthetic Aperture Radar-2 (PALSAR-2) aboard the Advanced Land Observing Satellite- 2 (ALOS-2, "DAICHI-2") is the latest L-band spaceborne synthetic aperture radar (SAR). PALSAR-2 observes the world mainly with 10 m resolution / 70 km swath Stripmap mode and 25 m resolution / 350 km swath ScanSAR mode. The 3-m resolution Stripmap mode is mainly used upon Japan. 350 km ScanSAR observation could detect large scale deformation e.g., the Mw 7.8 Gorkha, Nepal earthquake and its aftershocks in 2015. ALOS-2 ScanSAR is the first one that supports ScanSAR-ScanSAR interferometry in L-band spaceborne SAR. However, because of the parameter setting error for the orbit estimation, ALOS-2 PALSAR-2 ScanSAR could achieve little number of interferometric pair until the software modification on February 8, 2015. That is, the burst overlap timing required for the interferometric analysis was insufficient and it depends on the observation date. In this paper, we report the investigation results of this case and discuss the current status of the ALOS-2 ScanSAR InSAR. Some archives achieved before February 8, 2015 can be used for interferometric analysis with after Feb. 8. However, most of them have no interferometric pair. We also report that the archives acquired after February 8, have enough burst overlapping.

    InSAR (Interferometric Synthetic Aperture Radar) and D-InSAR (Differential InSAR) are rapidly developed new technologies of space geodesy during the late 20th century, and now obviously become hot research topics in the field of microwave remote sensing. Compared with the other sensors, InSAR possesses many incomparable advantages such as the capability to work at all-time and under all weather, very high spatial resolution and strong penetrability through the ground surface. This paper introduces general status of SAR, InSAR, D-InSAR technology, and the principles of InSAR and D-InSAR. New theories and the potential problems of (D-)InSAR technology are largely discussed, including multi-baseline interferometry, Pol-InSAR technique, the correction of atmospheric effects, permanent Scatterers method, the synthesization technique between InSAR and GPS, LIDAR etc., and the InSAR parallel algorithm. Then the new applications of InSAR and D-InSAR are described in detail including 3D topographic mapping, deformation monitoring (including surface subsidence, landside monitoring and ITRF's foundation and maintenance, etc.), thematic mapping (including agriculture and forestry, oceanic surveying and flood monitoring, etc.) and meteorology etc.. Finally, the prospect and future trends in InSAR development are summarized.

    2015-03-01

    Over 10 years have passed since the deadly human coronavirus that causes severe acute respiratory syndrome (SARS-CoV) emerged from the Guangdong Province of China. Despite the fact that the SARS-CoV pandemic infected over 8500 individuals, claimed over 800 lives and cost billions of dollars in economic loss worldwide, there still are no clinically approved antiviral drugs, vaccines or monoclonal antibody therapies to treat SARS-CoV infections. The recent emergence of the deadly human coronavirus that causes Middle East respiratory syndrome (MERS-CoV) is a sobering reminder that new and deadly coronaviruses can emerge at any time with the potential to become pandemics. Therefore, the continued development of therapeutic and prophylactic countermeasures to potentially deadly coronaviruses is warranted. The coronaviral proteases, papain-like protease (PLpro) and 3C-like protease (3CLpro), are attractive antiviral drug targets because they are essential for coronaviral replication. Although the primary function of PLpro and 3CLpro are to process the viral polyprotein in a coordinated manner, PLpro has the additional function of stripping ubiquitin and ISG15 from host-cell proteins to aid coronaviruses in their evasion of the host innate immune responses. Therefore, targeting PLpro with antiviral drugs may have an advantage in not only inhibiting viral replication but also inhibiting the dysregulation of signaling cascades in infected cells that may lead to cell death in surrounding, uninfected cells. This review provides an up-to-date discussion on the SARS-CoV papain-like protease including a brief overview of the SARS-CoV genome and replication followed by a more in-depth discussion on the structure and catalytic mechanism of SARS-CoV PLpro, the multiple cellular functions of SARS-CoV PLpro, the inhibition of SARS-CoV PLpro by small molecule inhibitors, and the prospect of inhibiting papain-like protease from other coronaviruses. This paper forms part of a series of

    FDA reviewers need a means to rapidly predict organ-specific carcinogenicity to aid in evaluating new chemicals submitted for approval. This research addressed the building of a database to use in developing a predictive model for such an application based on structure-activity relationships (SAR). The Internet availability of the Carcinogenic Potency Database (CPDB) provided a solid foundation on which to base such a model. The addition of molecular structures to the CPDB provided the extra ingredient necessary for SAR analyses. However, the CPDB had to be compressed from a multirecord to a single record per chemical database; multiple records representing each gender, species, route of administration, and organ-specific toxicity had to be summarized into a single record for each study. Multiple studies on a single chemical had to be further reduced based on a hierarchical scheme. Structural cleanup involved removal of all chemicals that would impede the accurate generation of SAR type descriptors from commercial software programs; that is, inorganic chemicals, mixtures, and organometallics were removed. Counterions such as Na, K, sulfates, hydrates, and salts were also removed for structural consistency. Structural modification sometimes resulted in duplicate records that also had to be reduced to a single record based on the hierarchical scheme. The modified database containing 999 chemicals was evaluated for liver-specific carcinogenicity using a variety of analysis techniques. These preliminary analyses all yielded approximately the same results with an overall predictability of about 63%, which was comprised of a sensitivity of about 30% and a specificity of about 77%.

    2015-06-01

    Antenna trajectory or motion errors are pervasive in synthetic aperture radar (SAR) imaging. Motion errors typically result in smearing and positioning errors in SAR images. Understanding the relationship between the trajectory errors and position errors in reconstructed images is essential in forming focused SAR images. Existing studies on the effect of antenna motion errors are limited to certain geometries, trajectory error models or monostatic SAR configuration. In this paper, we present an analysis of position errors in bistatic SAR imagery due to antenna motion errors. Bistatic SAR imagery is becoming increasingly important in the context of passive imaging and multi-sensor imaging. Our analysis provides an explicit quantitative relationship between the trajectory errors and the positioning errors in bistatic SAR images. The analysis is applicable to arbitrary trajectory errors and arbitrary imaging geometries including wide apertures and large scenes. We present extensive numerical simulations to validate the analysis and to illustrate the results in commonly used bistatic configurations and certain trajectory error models.

    Differential SAR-Interferometry (D-InSAR) is one of the potential source to measure land surface motion induced due to underground coal mining. However, this technique has many limitation such as atmospheric in homogeneities, spatial de-correlation, and temporal decorrelation. Persistent Scatterer Interferometry synthetic aperture radar (PS-InSAR) belongs to a family of time series InSAR technique, which utilizes the properties of some of the stable natural and anthropogenic targets which remain coherent over long time period. In this study PS-InSAR technique has been used to monitor land subsidence over selected location of Jharia Coal field which has been correlated with the ground levelling measurement. This time series deformation observed using PS InSAR helped us to understand the nature of the ground surface deformation due to underground mining activity.

    Full Text Available This study presents a new method of Synthetic Aperture Radar (SAR image target recognition based on a convolutional neural network. First, we introduce a class separability measure into the cost function to improve this network’s ability to distinguish between categories. Then, we extract SAR image features using the improved convolutional neural network and classify these features using a support vector machine. Experimental results using moving and stationary target acquisition and recognition SAR datasets prove the validity of this method.

    The application of synthetic aperture radar (SAR) for geologic mapping in Greenland is investigated by the Danish Center for Remote Sensing (DCRS) in co-operation with the Danish Lithosphere Centre (DLC). In 1994 a pilot project was conducted in East Greenland. The Danish airborne SAR, EMISAR......, acquired fully polarimetric C-band data which, upon processing and calibration, was interpreted jointly by DCRS and DLC. Several geologic phenomena are readily identified in the SAR imagery, while different lithologies seem to be indistinguishable because they have similar geomorphologies. The geologic...

  2. Analysis of Resolution of Bistatic SAR

    Institute of Scientific and Technical Information of China (English)

    2007-01-01

    In this paper, the spatial resolutions at different directions of bistatic synthetic aperture radar (BiSAR) have been derived from the ambiguity function. Compared with monostatic signal to noise ratio, BiSAR's resolutions of a fixed point target are varying with slow time since BiSAR system is space-variant. Constraints for the assumption of space-invariant bistatic topology are proposed in the paper. Moreover, under the assumption of invariance, the change of resolutions at different point in the image scene is taken into account, and we have specified two key parameters that affect resolutions directly and analyzed the way how they influence on the resolutions.

    1980-01-01

    Applications of Synthetic Aperture Radar (SAR) technology to the observation of coastal zones phenomena are detailed. The conditions observed include gravity wave detection, surf zone location, surface currents, and long-period 'surf beats'. Algorithms have been developed and successfully tested that determine significant wave and current parameters from the sea surface backscatter of microwave energy. Doppler information from the SAR optical correlator allows a rough estimation of near shore surface flow velocities that has been found in agreement with both theory and in situ observations as well. Seasat SAR data of the Scotland and North Carolina coasts are considered, as well as the results of bathymetric updating of coastal area charts.

    Calorimetric measurements were performed to determine the average specific absorption rates (SAR) resulting from MRI head examinations. The data were compared with average head coil SAR estimates displayed by the MR scanner in order to refine the imaging protocols used in imaging patients with implanted deep brain stimulators (DBS). The experiments were performed using transmit-receive (TR) head coil on clinical 1.5 T General Electric MR scanners running 11.0 M4 revision software. The average applied SAR was derived from temperature increases measured inside a head phantom, due to deposition of RF energy during MRI scanning with a spin echo imaging sequence. The measurements were repeated for varied levels of RF transmit gain (TG) and analyzed with a range of entered patient weights. The measurements demonstrate that the ratio of the actual average head SAR to the scanner-displayed value (coil correction factor) decreases for decreasing TG or for increasing patient weight and may vary between 0.3 and 2.1. An additional retrospective patient study, however, shows that not all combinations of TG and patient weight are encountered clinically and, instead, TG generally increases with the patient weight. As a result, a much narrower range of coil correction factors (e.g., typically 0.5-1.0) will be encountered in practice. The calorimetric method described in this work could aid the physicians and technologists in refinement of the model-dependent SAR estimates displayed by the MR scanner, and in selection of imaging parameters for MR head examinations within allowable SAR safety levels.

    2014-05-01

    We analyze different geosynchronous Synthetic Aperture RADAR concepts aimed to get both tropospheric and ionospheric delay maps with a revisit time of minutes and sub-continental coverage. Such products could be used either to compensate the delay in LEO-SAR missions and GNSS, or to generate integrated water-vapor maps to be used for Numerical Weather Forecast. The system exploits the principle of RADAR location, by transmitting a pulse with a suitable bandwidth, and the residual non-zero eccentricity of COMmunication SATellites. Different concepts are proposed as payload in COMSAT, or constellations of small satellites, that is monostatic or bistatic/multistatic RADARS. The selection of the best frequency, from L to Ku, and the analysis of performances is presented.

    Stott, Tim

    2010-05-01

    In Universities the benefits of teaching and learning through fieldwork has been brought under closer examination in recent years (e.g. Andrews et al., 2003) and the notion of supporting fieldwork in the Geography, Earth and Environmental Science (GEES) disciplines has been gathering momentum over the past decade as evidenced by conferences on ‘Supporting fieldwork using information technology' (Maskall et al., 2007) and a Higher Education Academy GEES Virtual Fieldwork Conference at University of Worcester (May 2007). Virtual environments and e-learning resources have been shown to help students become active rather than passive learners by appealing to their multi-sensory learning ability with interactive media (Fletcher et al., 2002; 2007). Research on glacial and fluvial processes has been conducted since 2003 by Liverpool John Moores University (LJMU) staff, sometimes in collaboration with other Universities, at field sites in the French Alps, Swiss Alps and Cariboo Mountains in British Columbia. A virtual field guide (VFG) (www.virtualalps.co.uk) has been developed which uses maps, site photos, panorama movies, video clips, a google earth tour, student exercises using hydrological and glacial datasets collected in the field and revision exercises. A preliminary evaluation of this learning resource has been carried out with two groups of LJMU students and an article written (Stott et al. 2009a). The Ingleton Waterfalls VFG (http://www.ljmu.ac.uk/BIE/ingleton/) was developed by LJMU staff to meet the needs of Foundation degree and undergraduate students. A workshop was presented at the Earth Science Teachers Association 2008 Annual Conference at LJMU, and a subsequent article written (Stott et al. 2009b). The final section of this presentation will summarise some staff perspectives and raises some questions and issues concerned with development and accessibility of VFGs in the light of new developments of a ‘semantic web' at LJMU (Carmichael, 2009).

    sentido común, como creencias, mitos, estigmas, miedos, que contribuyen a dar significado al problema denominado SIDA.OBJECTIVE: To analyze the social representation of AIDS in a group of high school students aged 16 to 23 years in Mexico City. MATERIAL AND METHODS: A non-probabilistic, cross-sectional research was carried out in a public high school in Mexico City. Students of all grades were invited to participate in the study, which took place between 1999 and 2000. Forty-six students participated; 28% male and 72% female. This exploratory field study consisted of three phases, each to address one of three dimensions: cognitive using free association techniques, representational field using semi-structured interviews; and context attitude by means of two discussion groups. In the latter, the information was previously collected for discussion. RESULTS: The cognitive nucleus on AIDS included the association between sex, disease, and death. The representational field of AIDS is constructed around the transmission-prevention unit. Construct elements are virus, contagion, sex, protection, and condom. An ambivalent attitude was identified towards HIV prevention and transmission: "We are only half responsible". Situations such as "rape, blood transfusions, infected syringes"were prominent in the discussion group, deemed beyond their control to prevent transmission, thus explaining the group's ambivalent attitude towards prevention. The usefulness of condoms was associated with prevention of pregnancy rather than with prevention of sexually transmitted infections. CONCLUSIONS: The social representation of HIV/AIDS in young students conforms a multidimensional corpus where different elements of scientific order and common sense converge and interact, such as beliefs, myths, taboos, and fears. All of these contribute to construct the meaning of AIDS.

    2016-01-01

    For spaceborne synthetic aperture radar (SAR) ima-ging, the dispersive ionosphere has significant effects on the pro-pagation of the low frequency (especial y P-band) radar signal. The ionospheric effects can be a significant source of the phase error in the radar signal, which causes a degeneration of the image quality in spaceborne SAR imaging system. The background ionospheric effects on spaceborne SAR through modeling and simulation are analyzed, and the qualitative and quantitative analysis based on the spatio-temporal variability of the ionosphere is given. A novel ionosphere correction algorithm (ICA) is proposed to deal with the ionospheric effects on the low frequency spaceborne SAR radar signal. With the proposed algorithm, the degradation of the image quality caused by the ionosphere is corrected. The simulation re-sults show the effectiveness of the proposed algorithm.

    TanDEM-X (TDX) enables to generate an interferometric coherence without temporal decorrelation effect that is the most critical factor for a successful Pol-InSAR inversion, as have recently been used for forest parameter retrieval. This paper presents mangrove forest height estimation only using single-pass/single-baseline/dual-polarization TDX data by means of new dual-Pol-InSAR inversion technique. To overcome a lack of one polarization in a conventional Pol- InSAR inversion (i.e. an underdetermined problem), the ground phase in the Pol-InSAR model is directly estimated from TDX interferograms assuming flat underlying topography in mangrove forest. The inversion result is validated against lidar measurement data (NASA's G-LiHT data).

  4. Optimal Approach to SAR Image Despeckling

    Institute of Scientific and Technical Information of China (English)

    2002-01-01

    Speckle filtering of synthetic aperture radar (SAR) images while preserving the spatial signal variability (texture and fine structures) still remains a challenge. Many algorithms have been proposed for the SAR imagery despeckling. However,simulated annealing (SA) method is one of excellent choices currently. A critical problem in the study on SA is to provide appropriate cooling schedules that ensure fast convergence to near-optimal solutions. This paper gives a new necessary and sufficient condition for the cooling schedule so that the algorithm state converges in all probability to the set of globally minimum cost states.Moreover, it constructs an appropriate objective function for SAR image despeckling. An experimental result of the actual SAR image processing is obtained.

    2016-06-01

    This paper proposes a science and technology education program to teach junior high school students to measure terrain changes by using interferometric synthetic aperture radar (SAR). The objectives of the proposed program are to evaluate and use information technology by performing SAR data processing in order to measure ground deformation, and to incorporate an understanding of Earth sciences by analyzing interferometric SAR processing results. To draft the teaching guidance plan for the developed education program, this study considers both science and technology education. The education program was used in a Japanese junior high school. An educational SAR processor developed by the authors and the customized Delft object-oriented radar interferometric software package were employed. Earthquakes as diastrophism events were chosen as practical teaching materials. The selected events indicate clear ground deformation in differential interferograms with high coherence levels. The learners were able to investigate the ground deformations and disasters caused by the events. They interactively used computers and became skilled at recognizing the knowledge and techniques of information technology, and then they evaluated the technology. Based on the results of pre- and post-questionnaire surveys and self-evaluation by the learners, it was clarified that the proposed program was applicable for junior high school education, and the learners recognized the usefulness of Earth observation technology by using interferometric SAR. The usefulness of the teaching materials in the learning activities was also shown through the practical teaching experience.

    2004-01-01

    Severe acute respiratory syndrome (SARS), a new, highly contagious, viral disease, emerged in China late in 2002 and quickly spread to 32 countries and regions causing in excess of 774 deaths and 8098 infections worldwide. In the absence of a rapid diagnostic test, therapy or vaccine, isolation of individuals diagnosed with SARS and quarantine of individuals feared exposed to SARS virus were used to control the spread of infection. We examine mathematically the impact of isolation and quarantine on the control of SARS during the outbreaks in Toronto, Hong Kong, Singapore and Beijing using a deterministic model that closely mimics the data for cumulative infected cases and SARS-related deaths in the first three regions but not in Beijing until mid-April, when China started to report data more accurately. The results reveal that achieving a reduction in the contact rate between susceptible and diseased individuals by isolating the latter is a critically important strategy that can control SARS outbreaks with or without quarantine. An optimal isolation programme entails timely implementation under stringent hygienic precautions defined by a critical threshold value. Values below this threshold lead to control, but those above are associated with the incidence of new community outbreaks or nosocomial infections, a known cause for the spread of SARS in each region. Allocation of resources to implement optimal isolation is more effective than to implement sub-optimal isolation and quarantine together. A community-wide eradication of SARS is feasible if optimal isolation is combined with a highly effective screening programme at the points of entry. PMID:15539347

    This study was conducted at a single hospital selected in Taipei during the SARS (Severe Acute Respiratory Syndrome) outbreak from March to July, 2003 in Taiwan. During this period of time, 104 SARS patients were admitted to the hospital. There were no negative reports related to the selected hospital despite its being located right in the center of an area struck by the epidemic. The purpose of this study was to identify the key factors enabling the hospital to survive SARS unscathed. Data were collected from in-depth interviews with the nursing directors and nursing managers of the SARS units, along with a review of relevant hospital documents. The five key elements identified as survival factors during this SARS crisis are as follows: 1. good control of timing for crisis management, 2. careful decision-making, 3. thorough implementation, 4. effective communication, and 5. trust between management and employees. The results of this study reconfirmed the selected hospital as a model for good crisis management during the SARS epidemic.

    Terry, Paul E; Mhloyi, Marvelous; Masvaure, Tsitsi B; Adlis, Susan A

    We assess gender differences in HIV prevention knowledge, attitudes and practices with a focus on cultural, sociological, and economic variables. A randomized cross-sectional study was used in order to achieve high participation and broad comparative assessment. An eight-page questionnaire was administered to 933 randomly selected students at the University of Zimbabwe. Survey items addressed sexual decision-making, condom use, limiting sexual partners, cultural power dynamics and access to HIV testing. We found marked gender differences with men reporting beliefs of entitlement to dominate women, an assumed leadership in decision-making concerning condom use and an attitude that when a woman says "no" to sex, really, "it depends." Women acknowledged gender-based cultural attitudes but are much more likely to support women's rights to sexual expression. A multi-faceted approach to gender equity training is needed to challenge men and women to change attitudes and increase social awareness that respects cultural traditions while still inspiring both men and women to champion justice and equality between genders.

    Image enhancements lead to improved performance and increased accuracy of feature extraction, recognition, identification, classification and hence change detection. This increases the utility of remote sensing to suit environmental applications and aid disaster monitoring of geohazards involving large areas. The main aim of this study was to compare the effect of image enhancement applied to synthetic aperture radar (SAR) data and Landsat 8 imagery in landslide identification and mapping. The methodology involved pre-processing Landsat 8 imagery, image co-registration, despeckling of the SAR data, after which Landsat 8 imagery was enhanced by Principal and Independent Component Analysis (PCA and ICA), a spectral index involving bands 7 and 4, and using a False Colour Composite (FCC) with the components bearing the most geologic information. The SAR data were processed using textural and edge filters, and computation of SAR incoherence. The enhanced spatial, textural and edge information from the SAR data was incorporated to the spectral information from Landsat 8 imagery during the knowledge based classification. The methodology was tested in the central highlands of Kenya, characterized by rugged terrain and frequent rainfall induced landslides. The results showed that the SAR data complemented Landsat 8 data which had enriched spectral information afforded by the FCC with enhanced geologic information. The SAR classification depicted landslides along the ridges and lineaments, important information lacking in the Landsat 8 image classification. The success of landslide identification and classification was attributed to the enhanced geologic features by spectral, textural and roughness properties.

  18. SAR-PC: Edge Detection in SAR Images via an Advanced Phase Congruency Model

    Directory of Open Access Journals (Sweden)

    2017-02-01

    Full Text Available Edge detection in Synthetic Aperture Radar (SAR images has been a challenging task due to the speckle noise. Ratio-based edge detectors are robust operators for SAR images that provide constant false alarm rates, but they are only optimal for step edges. Edge detectors developed by the phase congruency model provide the identification of different types of edge features, but they suffer from speckle noise. By combining the advantages of the two edge detectors, we propose a SAR phase congruency detector (SAR-PC. Firstly, an improved local energy model for SAR images is obtained by replacing the convolution of raw image and the quadrature filters by the ratio responses. Secondly, a new noise level is estimated for the multiplicative noise. Substituting the SAR local energy and the new noise level into the phase congruency model, SAR-PC is derived. Edge response corresponds to the max moment of SAR-PC. We compare the proposed detector with the ratio-based edge detectors and the phase congruency edge detectors. Receiver Operating Characteristic (ROC curves and visual effects are used to evaluate the performance. Experimental results of simulated images and real-world images show that the proposed edge detector is robust to speckle noise and it provides a consecutive edge response.

    Hummel, Robert

    1993-01-01

    The 'Multiresolution Analysis of SAR Data' program supported research work in five areas. Geometric hashing theory can now be viewed as a Bayesian approach to object recognition. False alarm rates can be greatly reduced by using certain enhancements and modifications developed under this project. Geometric hashing algorithms now exist for the Connection Machine. Recognition of synthetically-produced dot arrays was demonstrated using a model base of 1024 objects. The work represents a substantial advance over existing model-based vision capabilities. Algorithms were developed for determining the translation and rotation of a sensor given only the image flow field data. These are new algorithms, and are much more stable than existing computer vision algorithms for this task. The algorithms might provide independent verification of gyroscopic data, or might be used to compute relative motion with respect to a moving scene object, or may be useful for motion-based segmentation. Our theories explaining the Dempster/Shafer calculus and developing new uncertainty reasoning calculi were extended, and presented at a conference and were incorporated into the Bayesian interpretation of geometric hashing. 'Wavelet Slice Theorem' was developed in several different versions, any of which yields an alternate approach to image formation. The result may well provide a more stable approach to image formation than the standard Fourier-based projection slide theorem, since interpolation of unknown spectra values is better-founded.

    There is a history and understanding of exploiting moving targets within ground moving target indicator (GMTI) data, including methods for modeling performance. However, many assumptions valid for GMTI processing are invalid for synthetic aperture radar (SAR) data. For example, traditional GMTI processing assumes targets are exo-clutter and a system that uses a GMTI waveform, i.e. low bandwidth (BW) and low pulse repetition frequency (PRF). Conversely, SAR imagery is typically formed to focus data at zero Doppler and requires high BW and high PRF. Therefore, many of the techniques used in performance estimation of GMTI systems are not valid for SAR data. However, as demonstrated by papers in the recent literature,1-11 there is interest in exploiting moving targets within SAR data. The techniques employed vary widely, including filter banks to form images at multiple Dopplers, performing smear detection, and attempting to address the issue through waveform design. The above work validates the need for moving target exploitation in SAR data, but it does not represent a theory allowing for the prediction or bounding of performance. This work develops an approach to estimate and/or bound performance for moving target exploitation specific to SAR data. Synthetic SAR data is generated across a range of sensor, environment, and target parameters to test the exploitation algorithms under specific conditions. This provides a design tool allowing radar systems to be tuned for specific moving target exploitation applications. In summary, we derive a set of rules that bound the performance of specific moving target exploitation algorithms under variable operating conditions.

    Full Text Available Abstract Background During the SARS epidemic, healthcare utilization and medical services decreased significantly. However, the long-term impact of SARS on hospital performance needs to be further discussed. Methods A municipal hospital in Taipei City was shut down for a month due to SARS and then became the designated SARS and infectious disease hospital for the city. This study collected the outpatient, inpatient and emergency service volumes for every year from April to March over four years. Average monthly service amount ± standard deviation were used to compare patient volume for the whole hospital, as well as the outpatient numbers accessing different departments. The ARIMA model of outpatient volume in the pre-SARS year was developed. Results The average monthly service volume of outpatient visits for the base year 2002 was 52317 ± 4204 visits per month, and number for 2003 and the following two years were 55%, 82% and 84% of the base year respectively. The average emergency service volume was 4382 ± 356 visits per month at the base year and this became 45%, 77% and 87% of the base year for the following three years respectively. Average inpatient service volume was 8520 ± 909 inpatient days per month at the base year becoming 43%, 81% and 87% of the base year for the following three years respectively. Only the emergency service volume had recovered to the level of a non-significant difference at the second year after SARS. In addition, the departments of family medicine, metabolism and nephrology reached the 2002 patient number in 2003. The ARIMA (2,1,0 model was the most suitable for outpatient volume in pre-SARS year. The MAPE of the ARIMA (2,1,0 model for the pre-SARS year was 6.9%, and 43.2%, 10.6%, 6.2% for following 3 years. Conclusion This study demonstrates that if a hospital is completely shut down due to SARS or a similar disease, the impact is longer than previous reported and different departments may experience

    Infection of healthcare workers with the severe acute respiratory syndrome-associated coronavirus (SARS-CoV) is thought to occur primarily by either contact or large respiratory droplet transmission. However, infrequent healthcare worker infections occurred despite the use of contact and droplet precautions, particularly during certain aerosol-generating medical procedures. We investigated a possible cluster of SARS-CoV infections in healthcare workers who used contact and droplet precautions during attempted cardiopulmonary resuscitation of a SARS patient. Unlike previously reported instances of transmission during aerosol-generating procedures, the index case-patient was unresponsive, and the intubation procedure was performed quickly and without difficulty. However, before intubation, the patient was ventilated with a bag-valve-mask that may have contributed to aerosolization of SARS-CoV. On the basis of the results of this investigation and previous reports of SARS transmission during aerosol-generating procedures, a systematic approach to the problem is outlined, including the use of the following: 1) administrative controls, 2) environmental engineering controls, 3) personal protective equipment, and 4) quality control.

  11. A modified algorithm for SAR parallel imaging

    HU Ju-rong; WANG Fei; CAO Ning; LU Hao

    2009-01-01

    Synthetic aperture radar can provide two dimension images by converting the acquired echoed SAR signal to targets coordinate and reflectivity. With the advancement of sophisticated SAR signal processing, more and more SAR imaging methods have been proposed for synthetic aperture radar which works at near field and the Fresnel approximation is not appropriate. Time domain correlation is a kind of digital reconstruction method based on processing the synthetic aperture radar data in the two-dimensional frequency domain via Fourier transform. It reconstructs SAR image via simply correlation without any need for approximation or interpolation. But its high computational cost for correlation makes it unsuitable for real time imaging. In order to reduce the computational burden a modified algorithm about time domain correlation was given in this paper. It also can take full advantage of parallel computations of the imaging processor. Its practical implementation was proposed and the preliminary simulation results were presented. Simulation results show that the proposed algorithm is a computationally efficient way of implementing the reconstruction in real time SAR image processing.

  12. Automated rectification and geocoding of SAR imagery

    Kwok, R.; Curlander, J. C.

    1987-01-01

    An automated post-processing system has been developed for rectification and geocoding of SAR (Synthetic Aperture Radar) imagery. The system uses as input a raw uncorrected image from the operational SAR correlator, and produces as a standard output a rectified and geocoded product. The accurate geolocation of SAR image pixels is provided by a spatial transformation model which maps the slant range-azimuth SAR image pixels into their location on a prespecified map grid. This model predicts the geodetic location of each pixel by utilizing: the sensor platform position; a geoid model; the parameters of the data collection system and the processing parameters used in the SAR correlator. Based on their geodetic locations, the pixels are mapped by using the desired cartographic projection equations. This rectification and geocoding technique has been tested with Seasat and SIR-B images. The test results demonstrate absolute location uncertainty of less than 50 m and relative distortion (scale factor and skew) of less than 0.1 percent relative to local variations from the assumed geoid.

    2011-06-01

    We present a low-complexity method for compression of raw Synthetic Aperture Radar (SAR) data. Raw SAR data is typically acquired using a satellite or airborne platform without sufficient computational capabilities to process the data and generate a SAR image on-board. Hence, the raw data needs to be compressed and transmitted to the ground station, where SAR image formation can be carried out. To perform low-complexity compression, our method uses 1-dimensional transforms, followed by quantization and entropy coding. In contrast to previous approaches, which send uncompressed or Huffman-coded bits, we achieve more efficient entropy coding using an arithmetic coder that responds to a continuously updated probability distribution. We present experimental results on compression of raw Ku-SAR data. In those we evaluate the effect of the length of the transform on compression performance and demonstrate the advantages of the proposed framework over a state-of-the-art low complexity scheme called Block Adaptive Quantization (BAQ).

    To prevent SARS from spreading through air travel and in order to rebuild the confidence of the traveling public in the safety of air travel, ICAO has set up an "Anti-SARS Airport Evaluation Project." The first phase of this project was to develop a set of protective measures for international airports in affected areas to adopt and implement and then to send out, on the request of Contracting States, a team of inspectors to evaluate and assess airports and issue a "statement of evaluation" that the airport inspected complies with the ICAO anti-SARS protective measures. In cooperation with the World Health Organization (WHO), the first part of phase 1 was completed in early June this year, and the second part of phase 1 followed soon after. By mid-July, five international airports in Southeast Asia had been inspected and found to be in full compliance with the ICAO anti-SARS protective measures. The success of this ICAO project is believed to have contributed significantly to the recovery of international air travel and related industries now taking place. Phase 2 of the project is now being developed. It is aimed at preventing a resurgence of SARS, but it also contains elements to make the methodology developed applicable to future outbreaks of any other communicable disease in which the mode of transmission could involve aviation and/or the need to prevent the spread of the disease by air travel.

    Full Text Available This study concentrates on the results of several advanced hybrid bistatic SAR experiments. The hybrid bistatic configuration applies to the case in which the transmitter and receiver are mounted on different types of platforms, e.g., spaceborne/airborne, airborne/stationary, spaceborne/stationary, and so on. Several hybrid bistatic SAR experiments have been performed successfully, i.e., TerraSAR-X/PAMIR, PAMIR/stationary, and TerraSAR-X/stationary. Furthermore, Multiple Baseline Interferometry SAR (MB-InSAR and Digital Beam-Forming (DBF technologies are validated in the TerraSAR-X/stationary configuration. Note that the DBF experiment results based on the spaceborne illuminator are discussed for the first time in SAR community. In addition, this paper emphasizes imaging geometry, image analysis, and focusing results.

    Despite infection control measures, breakthrough transmission of severe acute respiratory syndrome (SARS) occurred for many hospital workers in Hong Kong. We conducted a case-control study of 72 hospital workers with SARS and 144 matched controls. Inconsistent use of goggles, gowns, gloves, and caps was associated with a higher risk for SARS infection (unadjusted odds ratio 2.42 to 20.54, p < 0.05). The likelihood of SARS infection was strongly associated with the amount of personal protectio...

    PRF ambiguity is a potential problem for a spaceborne SAR operated at high frequencies. For a strip mode SAR, there were several approaches to solve this problem. This paper, however, addresses PRF ambiguity determination algorithms suitable for a burst mode SAR system such as the Radarsat ScanSAR. The candidate algorithms include the wavelength diversity algorithm, range look cross correlation algorithm, and multi-PRF algorithm.
