In this paper, we implemented heart rate measuring system using arduino. The system can be used as a way to prevent solitary deaths of the elderly living alone. Arduino and smart phone are connected by bluetooth module. A heart rate measuring sensor measures the heart rate and then transmit the measured data value to the smart phone. If the data value is higer or less than normal range, smart phone application activates voice alarm and sends the message to the set number.

In research for investigation of static balance performance, postural sway variables have often been normalized by each subject’s height. However, evidence for such normalization has been insufficient. The aim of this study was to investigate the associations of anthropometry with postural sway and their possible gender differences. Forty young subjects (20 men and 20 women) performed quiet standing on a force platform in feet-together stance. Significant gender differences were observed in the correlation of outcome measures with anthropometry. In women, postural balance performance deteriorated (sway size increased and mean stable time reduced) and sway frequencies increased with height and weight. In contrast, men showed insignificant change in balance performance, but a reduction in sway frequency with height and weight. Stepwise multiple regressions revealed that height and weight were the major determinants of outcome measures, and that their effects on outcome measures differed between genders. Extreme care must be taken in normalization of postural sway variables by anthropometric data.

Apraxia of eyelid closure is an uncommon condition characterized by difficulties in voluntary eye closing with preserved normal blinking. Meige’s syndrome is a disorder of adults, and is characterized by prolonged symmetric dystonic contraction of the orofacial muscles and blepharospasm. We report a case of apraxia of eyelid closure on the right eye with Meige’s syndrome on the left eye complicating a left middle cerebral artery territory infarction.
