Snellen Chart Based on Android Control

Eye vision is a person's visual acuity examination that is usually done using a snellen chart. Snellen chart is a poster that contains a number of letters that are different on each line with the letters getting closer to the bottom lines. Eye vision examination using a normal snellen chart is done at a distance of 6 meters because someone is considered normal if he is able to read on the 20/20 line in feet or 6/6 in meters. Snellen chart control android is an electronic snellen chart that controls the light transfer using Android. Commands originating from the mitapp application on android are sent to the bluetooth HC-05 module in the minsys Atmega16 circuit. Atmega 16 was chosen because it has a sufficient number of pins to control the displacement of the lights used by 23 lights. The appearance of the mitapp application has been adjusted to the letters contained in the snellen chart, making it easier for operator to correct the results of the readings that have been performed by the eye vision patient

Do We Need to Perform Bilateral Hip Bone Mineral Density Examination?

Background: Bone mineral density (BMD) measurement is one of the method for making osteoporosis diagnosis. World Health Organization (WHO) recommends the measurement of BMD conducted at antero-posterior lumbar vertebrae, unilateral hip (femur), and radius. However, there was a concern about osteoporosis under diagnosis if the measurement is only conducted at unilateral hip. Some studies found significant differences of BMD between both femur and evidence of the importance to examine both femur in making the diagnosis of osteoporosis. This study aims to determine anydifference between right and left femur BMD measurement and to investigate the bone status result with measurement of BMD of bilateral femur in Hasan Sadikin General Hospital. Methods: A retrospective study was conducted from June to November 2015. Patients who received dual-femur BMD testing using General Electrics (GE) Lunar Prodigy dual-energy x-ray absorptiometry at the DXA Facility in Hasan Sadikin General Hospital,Bandung between January 1, 2006 to December 31, 2014 were included. Statistical analysis performed to assess the difference and the correlation between theBMD of two femurs (g/cm2). T-scores of the subject were implemented into bone status according to WHO Diagnostic Criteria for Osteoporosis.Results: From sixty-one patients included in this study, there were difference bone status resulted from BMD of the femoral neck, Ward's triangle, trochanter, andtotal hip area between right and left femur, although no statistically significance were found. There was a positive correlation between BMD of right and left femurat all areas of femur. There were 16 subjects (26.1%) showed combination level of bone status (normal, osteopenia, or osteoporosis in one femur).Conclusion: BMD results in each area of the right and left femurs are different.Therefore, performing bilateral hip BMD examination as a routine measurement for makingdiagnosis of osteoporosis is important

Analisa Penyimpangan Iklim dari Fenomena Enso Menggunakan Model Korelasi Studi Kasus Bogor

Cases of climate anomalous in Indonesia, many have influences on the climate in several areas such as the dry or rainy season that does not occur periodically or the precipitation decrease that does not normal and deviated from ought. This study aimed to analyze the climate anomalous and correlation patterns of ENSO towards rainfall variability in Darmaga Bogor, then compared the results with rainfall of Tanjung Priok Jakarta. Both places have minimum ENSO influence because they being away from the center of ENSO events that is in the Pacific Ocean and located in the west Pacific. Climate anomalous due to ENSO (El Niño Southern Oscillation) in the Indonesian archipelago can occur if in the Pacific El Niño is more decreasing rainfalls or La Niña which further adds to the amount of rainfall.This research using a linear correlation analysis model and contour of the sea surface temperature (SST) from GrADS software. The data used are Index Nino 3.4 anomaly, IOD (Indian Ocean Dipole) anomaly, precipitation and SST anomaly data. Data is processed from January 2004 - December 2013 (10 years). Correlation of index Nino 3.4 years 2004-2013 showed a lot more going to negative index that means more towards the La Niña in Pacific Ocean. The results of correlation analysis in August in Darmaga between ENSO - IOD with rainfall that more affects the rainfall pattern is a ENSO factor either La Niña nor El Niño and also it followed by west monsoon wind pattern, whereas at Tanjung Priok that more affects the rainfall pattern is monsoonal rainfall patterns. Upon the precipitation in Darmaga generally has high enough intensity and some graph pattern follows monsoonal rainfall patterns whereas Tanjung Priok generally has low intensity and the graph pattern follows the type of monsoonal rainfall patterns. SST contour in West Java is on average warmed up that caused that region more easily condensed the clouds and atmospheric pressure at the waters becomes high
