Nowadays, due to the popularization of mobile phone, the functions and using manners of mobile phone have been varied. According to Korea National Statistical Office, the numbers of domestic mobile phone user were 30 million at the end of March 2002. A survey was conducted to investigate the various using manners of mobile phone, especially the young ones from 15 to 28 years old. Two hundred and sixty people participated in this study. According to the result of this study, text messaging was one of the major functions of the mobile phone for the young people. Also, continuous and repetitive use of small key pad of mobile phone for text messaging could cause the repetitive strain injury on hand, especially fingers.

Mobile instant messaging (MIM) has been widely used in modern society due to its portability, speed and ease of use. In addition to simple text-based messaging, mobile instant message has now expanded to include graphics, images, and video. Many instant message service providers attempt to differentiate their service by providing an unique emoticon. Therefore, understanding the factors that affecting the continuous usage of emoticon is essential to capture users' interest. There is relatively little study on emoticon in information systems field. Hence, this study attempts to explore the continuous usage of emoticon through exploring the property of emoticon and usage motivation of emoticon. Based on the results, this study attempts to demonstrate practical implication of marketing on understanding user interest to mobile instant messenger service provider.

The goal of the present study is to explore IM interruption by relating it to media choices and purposes of IM use in the workplace. Two major media choice concepts were: media richness and social influence; while four purposes of IM use were: organization work, knowledge work, socializing, and boundary spanning activities. Data (N = 283) were collected via a combination of convenience and snowball sampling of "computer-using workers" in Taiwan, based on the Standard Occupational Classification system published by the Taiwan government. Results indicated that media choice works better than purpose of IM use to explain IM interruption. Among them, social influence was the best predictor to IM interruption in the workplace. In addition, instant feedback and personalization provided by IM, and IM usage for the purposes of knowledge work and socializing, also relate to IM interruption in the workplace.

This paper is about the architectures of an extensible and scalable home automation system which is based on instant messaging. The extensibility is the most important feature of the system because there are very diverse appliances at home and they can be added or replaced with other products frequently. For the extensibility, we propose façade architecture for communication, distributed agent architecture for the system, layered architecture for agents, and bridge architecture for wrapping existing facilities. Using these architectures, we reduce the system complexity and get the extensibility to add new products with least cost. Furthermore, we also introduce our prototype system and show that it is extensible.

A method to detect Trojan horses in messaging and Bluetooth in mobile phones by means of monitoring the events produced by the infections is presented in this paper. The structure of the detection approach is split into two modules: the first is the Monitoring module which controls connection requests and sent/received files, and the second is the Graphical User module which shows messages and, under suspicious situations, reports the user about a possible malware. Prototypes have been implemented on different mobile operating systems to test its feasibility on real cellphone malware. Experimental results are shown to be promising since this approach effectively detects various known malware.

클러스터 내의 노드들 사이에서 대용량의 데이터들을 보다 빠르게 전송하기 위해서 경량 메세징(Lightweight Messaging) 기법이 등장하였다. 이 기법들 중 VIA(Virtual Interface Archi- tecture)는 사용자 수준에서 커널을 거치지 않고 네트워크 장치와 직접적으로 통신을 할 수 있게 하여 클러스터 시스템의 프로토콜로 자리를 잡아가고 있다. 그러나 이러한 장점에도 불구하고 프로그래밍이 어려워 제대로 숙지하기까지는 많은 시간의 투자가 필요한 것이 사실이다. 이 논문에서는 개발자들이 좀더 쉽게 VIA에 접근할 수 있는 EVIL(Easy-to-use Virtual Interface Library)을 제안하였다. 그리고 EVIL을 Native VIA, TCP/IP와 각각 성능을 비굔 평가하였다.

In this paper, we present some problems with the Groupware Messenger functionality based on dot net 2.0 and implement a new design structure to solve them. They include memory leakage, slow processing, and client window memory crash. These problems resulted in the inconvenience of using instant messaging and the inefficient handling of office tasks. Therefore, in this paper, instant messaging functionality is implemented according to a new design architecture. The new system upgrades dot net 4.5 for clients and deploys the new features based on MQTT for the messenger server. We verify that the memory leak problem and client window memory crash issues have been eliminated on the system with the new messenger functionality. We measure the amount of time it takes to bind data to a set of messages and evaluate the performance, compared to a given system. Through this comparative evaluation, we can see that the new system is more reliable and performing.
