Physiological Signal

Abstract Cell phones produce electromagnetic interference (EMI), which can cause artifacts in physiological recordings and be misinterpreted by the clinician. This study investigated the possible effect of EMI (electrical artifact) on physiological recordings when cell phones are activated/ringing. The procedure consisted of placing the cell phone at varying distances from surface electromyographic sensors. Depending on the orientation of the cell phone's antenna, the EMI produced an artifact in the physiological signal for up to 175 cm (6 ft) that can be misinterpreted by the therapist. To avoid EMI artifacts, clients and therapists should turn off their cell phones when recording physiological signals. This means turning the cell phone off and not just switching it to vibrate. In addition, recent epidemiological studies suggest that long-term intensive cell phone use may increase the risk of gliomas, auditory tumors, and salivary tumors on the side of the head to which the person places the cell phone. Thus, to reduce artifacts and biological harm, the authors recommend keeping the cell phone away from the body and the biofeedback equipment.

Cell phone or mobile phone is an electronic communications device that has same function with fixed-line telephone. This mobile phone can be taken anywhere and doesn’t need to be connected to the telephone network using a cable (wireless LAN). This study aims to describe the use of mobile phone, the average of expanse, and the use of mobile phone base on the division of the village. This survey was conducted face to face interviews with respondents using questionnaire. The selection of respondent in the household uses Kish Grid. Respondent who use mobile phone in the last three months are 39 people (81,3%). Respondent who is reported having a cell phone are 26 people (54,2%) with the detail users for smart phone are 16 people (61,5%) while non-smart phone users are 10 people (38,5%). The highest use of mobile phone in the last three months is in Ohotahit village, they are 15 people (93,8%) while the testimony of respondent who own mobile phone in Tamedan are 10 people (62,5%). Mean for the average expanse every month is Rp34.231,00. People hope that there will be a good, cheap, and affordable for network mobile phone or telephone installation and internet networks prepared as ICT infrastructure. Keywords: Use, Mobile phones, Fishermen Community     ABSTRAK Telepon genggam atau handphone (HP) merupakan perangkat telekomunikasi elektronik yang mempunyai kemampuan dasar yang sama dengan telepon konvensional saluran tetap.Mobile phone ini dapat dibawa ke mana-mana (portabel mobile) dan tidak perlu disambungkan dengan jaringan telepon menggunakan kabel (nirkabel, wireless). Penelitian ini bertujuan untuk mengetahui gambaran penggunaan telepon genggam, rata-rata pengeluaran, dan penggunaan telepon genggam berdasarkan pembagian desa. Survei ini dilakukan dengan melakukan wawancara tatap muka dengan responden menggunakan daftar pertanyaan (kuesioner). Pemilihan responden dalam rumah tangga menggunakan Kish Grid. Responden yang menggunakan telepon genggam dalam tiga bulan terakhir sebanyak 39 orang (81,3%). Responden yang menyatakan memiliki telepon genggam sebanyak 26 orang (54,2%) dengan rincian pengguna telepon genggam smartphone sebanyak 16 orang (61,5%), sedangkan pengguna telepon genggam nonsmartphone sebanyak 10 orang (38,5%). Penggunaan telepon genggam tertinggi dalam tiga bulan terakhir tertingi di Desa Ohotahit sebanyak 15 orang (93,8%), sedangkan pengakuan responden terkait kepemilikan telepon genggam tertinggi di Desa Tamedan sebanyak 10 orang (62,5%). Mean untuk rata-rata pengeluaran komunikasi setiap bulan yang dikeluarkan oleh responden Rp34.231,00. Masyarakat berharap agar ada pemasangan jaringan Telepon/HP dan Jaringan Internet yang baik, murah dan terjangkau disiapkan seperti sarana dan prasarana TIK.

Abstract Over the past 20 years, there have been many advances in the computer industry as well as in augmentative and alternative communication (AAC) devices. Computers are becoming more compact and have multiple purposes, such as the iPhone, which is a cell phone, mp3 player, and an Internet browser. AAC devices also have evolved to become multi-purpose devices; the most sophisticated devices have functionality similar to the iPhone and iPod. Recently, the idea of having the iPhone and iPad as a communication device was initiated with the development of language applications specifically for this format. It might be true that this idea could become the future of AAC devices; however, there are major access issues to overcome before the idea is a reality. This article will chronicle advancements in AAC devices, specifically on access methods, throughout the years, towards the transition to handheld devices. The newest technologies hold much promise with both features and affordability factors being highly attractive. Yet, these technologies must be made to incorporate alternate access if they are to meet their fullest potential as AAC tools.
