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.

A majority of the world’s population now live in areas with a mobile telephone network. This expansion of the network enables people to use more mobile phone functionalities such as short message service, multimedia, and the Internet. Mobile phone–based health (mHealth) interventions have been considered to have benefits in low-income countries. The aim of this study was to explore the feasibility of a short message service for breastfeeding education in Ethiopia. Four focus groups—two with mothers and two with fathers—were conducted with a total of 41 participants. The focus group discussion recordings were transcribed in Tigrigna verbatim, and then translated to English. The data were analyzed using thematic analysis, underpinned by the technology acceptance model. The following four general themes emerged from the focus group discussions: (1) Mobile phones: integrated into everyday life; (2) SMS text messaging: anytime, anywhere, as long as there is a sound; (3) Marketing versus utility: a barrier to SMS; and (4) Scientific messages from credible experts are key to reading SMS-based messages. Parents in Ethiopia showed interest in receiving weekly infant feeding-related short messages. Short message service–based interventions could therefore be an option for improving knowledge and awareness of parents regarding infant feeding.

Kemajuan perkembangan teknologi komputer dan telekomunikasi dapat membantu menyelesaikan pekerjaan dengan cepat, akurat dan efisien. Alat komunikasi yang banyak digunakan pada saat ini adalah mobile phone atau disebut juga telepon seluler. Salah satu teknologi yang digunakan untuk berkomunikasi pada mobile phone adalah dengan mengirimkan data berupa pesan singkat atau SMS (Short Message Service). Permasalahan yang ditemukan dalam berkomunikasi menggunakan mobile phone adalah pencurian, penyadapan, atau penghapusan data khususnya data SMS (Short Message Service) sehingga aspek keamanan data dianggap penting. Oleh karena itu dibutuhkan sistem kriptografi enkripsi dan dekripsi SMS, disini digunakan enkripsi simetris. Sistem ini merupakan aplikasi yang menerapkan metode zig zag cipher yang menggunakan kunci simtetris. Hasil pengujian dari sistem ini adalah pesan SMS dienkripsi dengan pola zig zag menggunakan kunci dan didekripsi menggunakan kunci yang sama dengan enkripsi.

The unprecedented global adoption of information and communication technologies (ICTs) is rapidly changing the way people are communicating in solving problems. For several years now, the role of ICTs has become important in the way people construct their relationships in conflict resolution. Yet little is known on the dynamism of this interaction. It is not clear how mobile technology has contributed toward conflict resolution, and this study will contribute to the knowledge on the role of mobile telephones in conflict resolution. The purpose of this study was to explore how the mobile phone technology contributed in resolving communal conflicts in Mandera County, Kenya. This study was guided by three theories: conflict transformation theory, diffusion of innovations theory and social representation theory. The conflict Tansformation Theory is adopted as the main theory of analysis.  The main idea of this theory is transforming negative conflict into constructive conflict, deals with structural, behavioural and attitudinal aspects of conflict. This study adopted a descriptive survey. The population for this study consisted of 301 employees in ICT and security department where stakeholders in technology and security sectors and the public. Primary and secondary  data was analysed according to the objectives. Primary data was derived from questionnaires formulated to target employees in ICT and security department. The data analysis included qualitative and quantitative techniques.  Qualitative data was summarized and categorized according to common themes and was presented using frequency distribution tables, graphs and charts. Content analysis was used mostly to arrive at inferences through a systematic and objective identification of the specific messages. The quantitative data collected was analyzed using descriptive statistics. The results confirmed that short message service, social media plateform, instant messaging applications, and video conferencing play a role in resolving communal conflicts in Mandera County. The study concludes that Short Message Service, Social Media Platforms and Instant Messaging Applications can be used conflict such as communal conflicts. Video Conferencing can be used to solve conflict such as relationship conflict, arises from differences in personality, style, matters of taste, and even conflict style as well as conflict in the workplace like task conflict. County government of Mandera must come up with ways of incorporating mobile phone technologies such as Short Message Service, Social Media Platforms, Instant Messaging and Video Conferencing on matters conflict resolution. The study recommends that the County Government of Mandera in collaboration with the National Government need to come up with agencies to regulate the use of social media as a medium to communicate in times of conflict since they are sometimes prone to misuse.

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
