Compressed sensing and magnetic resonance imaging are hot topics in the field of signal processing. In this study we introduced in Lustig’s variable density sampling method, integrated it to compressed sensing, and applied it to brain MRI acquisition. The realistic experiment shows the variable density sampling recovery better than traditional random sampling method on a 256x256 brain magnetic ...
This study aims to grasp the current condition of handovers of practical tasks among nursing students as well as specific items of handovers and the communication clarity. A questionnaire-based survey was conducted on handover experience among 137 individuals who had experience of clinical practice and were senior students at three nursing colleges located in A, B, and C districts. Among them, ...

BACKGROUND Artemisinin-based combination therapies are recommended by the World Health Organisation (WHO) as first-line treatment for Plasmodium falciparum malaria, yet medication must be of good quality for efficacious treatment. A recent meta-analysis reported 35% (796/2,296) of antimalarial drug samples from 21 Sub-Saharan African countries, purchased from outlets predominantly using conveni...
Following a needs assessment among residents, a 10-module leadership curriculum was developed that included health care law and medical errors. An educational intervention using the flipped classroom model (FCM) was developed and we investigated (1) its effectiveness as a teaching method, and (2) the degree of knowledge acquisition of the content of the module. Thirty-four residents were select...
PURPOSE The study was conducted to identify predictors of mammography screening for rural Korean women according to 'Stage of Change' from the Transtheoretical Model which, along with the Health Belief Model, formed the theoretical basis for this study. METHODS A cross-sectional descriptive design was utilized. Through convenience sampling 432 women were selected from 2 rural areas. Data were...
the aim of this study was to evaluate standard and safety indexes in tehran fitness gyms. the population consisted of state and private fitness clubs in tehran. 5 regions of tehran city were selected by cluster sampling method; then, 20 clubs from each region were selected by on non-random convenience sampling method, so a total of 100 fitness clubs were assessed. the aim of this study was app...
A method to improve l1 performance of the CS (Compressive Sampling) for signals with known spectral energy density is proposed. Instead of random sampling, the proposed method selects the location of samples to follow the distribution of the spectral energy. Samples collected from three different measurement methods; the uniform sampling, random sampling, and energy equipartition sampling, are ...
OBJECTIVE To compare ultrasonography with chest radiograph to detect the level of endotracheal tube tip in intubated neonates. DESIGN Observational. SETTING Neonatal care unit of a teaching hospital. PARTICIPANTS 53 neonates selected by convenience sampling. INTERVENTION Ultrasonography of chest was done with probe of 5 to 8 MHz using high parasternal view. The distance of the endotrach...
