Natural History Of Implantable Cardioverter-Defibrillator Implanted At Or After The Age Of 70 Years In A Veteran Population A Single Center Study

Background: The median age of patients in major Implantable Cardioverter-defibrillator (ICD)trials (MUSTT, MADIT-I, MADIT-II, and SCD-HeFT) was 63-67 years; with only 11% ≥70 years. There is little follow-up data on patients over 70 years of age who received an ICD for primary/secondary prevention of sudden cardiac death, particularly for veterans. Objective: The aim of this study was to study the natural history of ICD implantation for veterans over 70 years of age. Methods: We retrospectively reviewed single center ICD data in 216 patients with a mean age at implantation 76 ± 4 years. The ICD indication was primary prevention in 161 patients and secondary prevention in 55 patients. The ICD indication was unavailable in 4 patients. Results: Mean duration of follow up was 1686 ± 1244 days during which 114 (52%) patients died. Of these, 31% died without receiving any appropriate ICD therapy. Overall, 60/216 (28%) received appropriate therapy and 28/216 (13%) received inappropriate therapy. Patients who had ICD implantation for secondary prophylaxis had statistically more (p= 0.02) appropriate therapies compared to patients who had ICD implantation for primary prevention. Indication for implantation and hypertension predicted appropriate therapy, while age at the time of implantation and presence of atrial fibrillation predicted inappropriate therapies. Overall, 7.7% had device related complications. Conclusions: Although 28% septuagenarians in this study received appropriate ICD therapy, they had high rates of mortality, inappropriate therapy, and device complications. ICD implantation in the elderly merits individualized consideration, with higher benefit for secondary prevention

Students’ Perception on Female Teachers

As one of the pedagogic activities, teacher plays important roles to make students learn directly from their teachers in order to develop their cognition, affection, and psychomotor. In this case, there are some competencies have to be performed by all teachers, namely pedagogic, professional, personal, and social competencies as the requirements to teaching and learning activities. The facts show that many female teachers perform teacher competencies better than male teachers because of the meekness and good appearance of female teachers. This study was conducted to know the students’ perception on male teachers in English Education Department of Unismuh Makassar. The data were collected through interview, and analyzed descriptively in qualitative way. The findings indicated that the students mostly like female teachers because they perform almost all teacher competencies better. Therefore, it was concluded that female teachers are better than male teachers in English Education Department of Unismuh Makassar. Keywords: male and female teachers, pedagogic, professional, personal, and social competencies, performance, appearanc

Optimizing Indoor Temperature Control Using Genetic Algorithm for PID Tuning

This study was conducted to explore ways to save energy focusing on Temperature control through genetic algorithm (GA)based on the Proportional Integral Derivation controller (PID) to obtain the best PID gain parameters (kp, ki, kd) through which the settling time, steady state error, and overshoot are improved, which showed better performance than using traditional PID because of its fast and sharp control it provided. The best results for the parameters were using integrated time absolute error (ITAE)as a GA objective function where k [0.8598 0.0669 0]. However, by using Integrated of absolute error(IAE), the best results obtained were k [12.9765 0.2534 0], It is possible to improve system’s response from using traditional PID which is considered a long time (more than 25 seconds) as compared to the PID with Genetic algorithm(GA).       The study showed that the best results were obtained using the IAE as an objective function for GA, as the system reached the stable state in the shortest possible time.

Drivers of grassland loss in Hungary during the post-socialist transformation (1987–1999)

The increase in the speed of land-cover change experienced worldwide is becoming a growing concern. Major socio-economic transitions, such as the breakdown of socialism in Europe, may lead to particularly high rates of landscape transformations. In this paper we examined the loss of semi-natural grasslands in Hungary between 1987 and 1999. We studied the relationship between 9 potential driving forces and the fate of grasslands using logistic GLMs. Grassland loss was found to be very high (1.31 % per year), which is far higher than either before or after this period. The most influential predictors of grassland loss were environmental and landscape characteristics (soil type, area of remnant grassland patches), and the socio-economic context (distance to paved road, and nearest settlement, human population density). Several processes and relationships can only be understood from a historical perspective (e.g. large extent of afforestation, strong decrease of soil water table). Grassland loss during the study period emerged as a consequence of survival strategies of individual farmers seeking adaptation to the changing environmental and socio-economic conditions, and not urbanization and agricultural intensification which are the main underlying drivers for the ongoing landscape transformations in most parts of the developed world. Though globalization increasingly influences local land use decisions , reconstructing and modelling recent landscape changes cannot be done without a proper understanding of local history and culture. Our analysis shows the importance of large-area yet high resolution landscape change research, which may reveal unexpected patterns of land cover change, undetected at coarser scales

Characterisation of a multi-channel multiplexed EMG recording system: towards realising variable electrode configurations

First steps towards osseointegrated myoelec-trically-controlled prostheses: Bone anchor conduit conveys EMG signals from implanted electrodes [1]. In vivo selection of electrode configurations would improve signal-to-noise ratio (SNR) of EMG recordings [2]; optimal electrode config-urations are not known before implantation. The CAPITel system: Control of Active Prostheses using Implant-able Telemetry [3,4]. Implantable EMG amplifier with a novel multi-plexed frontend. In vivo selection of monopolar, bipolar or tripolar configurations. Designed using commercially available com-ponents for use in animal models. After further research design will be imple-mented as an ASIC

Assessing quality of healthcare service by the SERVQUAL model: A case study of a field hospital

Aims: Identifying quality gap of services provided by hospital lead to preparing improvement projects and programs. This study intends to determine the quality gap in healthcare services provided by Shahid Elmi Field Hospital from the view point of Patients. Methods: In this cross-sectional study, 100 patients admitted to the hospital in 2011 were selected randomly for the study. The data gathered through SERVQUAL Standard Questioner. The content validity and reliability was confirmed by specialist opinions and Cronbach's alpha coefficient, respectively. Data analysis was conducted using descriptive statistics and two-sample t, Pearson correlation and ANOVA tests, using SPSS version 18. Results: According to the patients' views, there is a positive quality gap in delivered services. The highest mean score of the negative and positive quality gap were related to Responsiveness (-0.02) and access (0.035) respectively. There was a significant relation between the frequency of referral and the quality empathy (p=0.05). Conclusion: According to the results, the delivered services of the studied Field hospital is higher than the expectations of patients. It is recommended that processes related to delivery of services, in all dimensions of services' quality particularly responsiveness and assurance, should be identified and reengineered

Promoting communication skills for information systems students in Australian and Portuguese higher education : action research study

This paper aims to examine the value of communication skills learn- ing process through various assessments in Information Systems (IS) postgrad- uate units in Australia and Portugal. Currently, communication skills are indispensable to students in expanding their social networks and their knowl- edge at university and in the future workplace, since businesses expect their employees to have strong communication and presentation skills. This paper provides empirical evidence based on the anonymous quantitative and qualita- tive data collected during 2 years from 126 postgraduate students, which were collected via formal and informal feedback. Various assessment methods were used in Information Systems units to promote and develop the communication skills; these assessments are: reflective journal, business plan and prototype, discussion forum, presentation, and final examination. A Communication skills model (CSM) was developed based on Action research principles to promote the assessments which will assist IS students to enhance their communication skills. The research outcomes indicated that integrating communication skills in the assessments will allow students to promote their communication skills and boost their self-esteem skills. Furthermore, this paper added a new theoretical and practical contribution to higher-education teaching and learning literature, especially the action research for teachers to promote and develop communica- tion skills among students. Finally, integrating these skills in the units should meet the objectives and aims of the units, Master’s degrees, universities, and businesses’ needs, and satisfy our student’s need
