Traditionally, cell phones have been considered disruptive to classroom learning. Two years ago, a survey of students in a large first year design course indicated that 88% of students possessed cell phones in the classroom. Instead of trying to enforce acell phone ban, and fight a losing battle, we decided to use the cell phones to our pedagogical advantage. Previously, student interaction in the classroom was a challenge, due to a large class of students in a singlelecture theater. A primary issue was the inability of all except a few students with booming voices to ask questions. Informed primarily by a student design team (from the very course being discussed), we implemented a simple and inexpensive system that allowed students to use their cell phones in the classroom to send questions via Short Message Service (SMS), commonly referred to as “text messages”, to the instructor at the front of the classroom This system has been piloted through its first year of full implementation. Quantitative data on the usage of the system, student and instructor impressions of the system, and future work will be discussed.

SMS (Short Message Service) is a popular communication technology revolution. The development of computerized technology has been very advanced. SMS is very vulnerable to data theft or theft by irresponsible parties. For the sake of maintaining the security of SMS can be done by using cryptographic techniques. Cryptographic techniques can encode text messages by encrypting them into passwords that are not understood. Mars algorithm is an algorithm that uses a 128-bit key and the encryption process consists of 32 rounds. This symmetry algorithm will produce a higher level of security for the ultrasound image because it can encode it into a form of cipher with a process that is complex enough so that it will be difficult for cryptanalysts to access the image. This research will use the Mars algorithm for the encryption and decryption process, so the process needs to go through several long stages in order to produce the final cipher. This study describes the process of securing SMS by encoding it based on the Mars algorithm, in the form of a password that is difficult for others to understand and understand. This is done as an effort to minimize acts of misuse of SMS

This paper presents an SMS based design in the GSM system for a portable, light weighted, and small sized TeleAlarm device. The device is composed of a transmitter and a controller. When an emergent situation such as a stroke or a fall occurs, the user only needs to push a button to trigger the controller. The controller automatically sends text messages stored in its database through the transmitter to specified mobile phone numbers for help. The SMS uses only the control channels in the GSM system to transfer the message, which enables the receiving-end user to receive it even during a call. An experimental test shows that a complete message transmission only needs 2.949 seconds in average. The design is convenient to elderly people who may live alone.

We identify the different styles of texting in Filipino short message service (SMS) texts and analyze the change in unigram and bigram frequencies due to these styles. Style preference vectors for sample texts were calculated and used to identify the style combination used by an average individual. The change in Shannon entropy of the SMS text is explained in light of a coding process.

The use of short message service (SMS) has grown tremendously in the past few years. Billions of users use this service to send text messages. Various applications have been introduced by service providers, e.g., mobile banking, summons checkpoint, SMS chat, etc., all of which have become a huge success. This chapter gives an overview of how this service is provided and discusses various SMS applications offered to the user. We explore the reasons behind its success and the issues that must be addressed to provide these applications. We also examine future trends and the challenges that must be overcome in order to enhance this service. We hope that this chapter gives a better understanding of how SMS applications are provided and what may be expected in future applications given the enhancement on the current SMS and technology advancement.

Abstract Background: Failure to attend the clinic without prior intimation, known as “Did Not Attend” (DNA) is a significant global issue. There have been no published studies attempting to reduce DNA rates in breast clinics. We aimed to assess the impact of contacting patients prior to clinic attendance and Short Message Service (SMS) reminder on DNA rates in rapid access new breast clinics, evaluate ‘Could Not Attend’ (CNA) rate, and explore any correlation between age, sex, clinic days and sessions.Methods: Initially, DNAs at the rapid access new breast clinic between 01/04/2018 and 31/03/2019 at a district general hospital in the North-West of England was assessed (Cycle 1). Changes were introduced in terms of contacting patients prior to offering appointments, followed by SMS reminders nearer the clinic dates. Subsequently, DNA was reassessed between 01/10/2019 and 31/03/2020 (Cycle 2). Results: Following implementation of changes, DNA rate reduced from 8.2% to 4.1% (p<0.00001). CNA rates were 0.9% (Cycle 1) and 1.1% (Cycle 2) [p=0.36]. Evening clinics had the lowest DNA rates throughout. DNA patients in cycle 2 were significantly older than those in cycle 1 (p=0.002). Conclusions: Contacting patients prior to clinic appointments and sending SMS reminders helped reduce DNA rates significantly in rapid access new breast clinics. Scheduling clinic sessions with least DNA rates, such as evening clinics, should be contemplated. One should be cautious of Mobile phone technology that conveys SMS, which can potentially disadvantage the older age group. This model could be considered across the board to improve DNA rates.

The aim of this study is to investigate the choice of alphabetical encoding in Greek text-messaging (or Short Message Service, SMS). The analysis will be based on a corpus of 447 text-messages exchanged among participants who belong to the age group of ‘youth’ (15-25 years old) and live in Athens (Greece). The data analysis will show that the standard practice of writing with Greek characters represents the norm in Greek SMS. The script norm will be discussed in relation to the medium’s technological affordances and the participants’ stance towards new media. The analysis will then focus on non-standard graphemic choices, such as the use of both, Greek and Roman, alphabets in the encoding of single messages. It will be demonstrated that such marked choices are employed as a means of indexing the participants’ affiliation with global popular cultures and enhancing expressivity in a medium of reduced paralinguistic cues.
