단문메시지서비스는 지난 몇년간 이동통신분야에서 괄목할만한 성장을 이루어 가장 보편적인 서비스중의 하나로 자리매김 하였으며, 현재는 가입자 상호간의 단순한 메시지 송수신뿐 아니라 각종 부가 정보를 제공하는 등 상업적인 용도로도 사용되고 있다. 이러한 이동통신망에서 단문메시지서비스의 광범위한 사용은 유선망에서도 기존 음성위주의 서비스를 벗어나 메시지서비스를 제공케 하였으며, 2002년 7월 현재 독일, 이탈리아와 한국등에서 유선망 메시지서비스를 제공하고 있다. 이에 본 문서는 지난 4월부터 제공되기 시작한 KT의 단문메시지서비스를 위한 유선망 문자메시지 서버의 구현과 망 구축 기술에 대하여 서술한다.

Since the advent of smart phone, a variety of text-based media are developed and used as popular communication tools even in mobile phone environment. This study explores differences in terms of users' perceived social presence level across different text-based media, specifically KakaoTalk, Facebook, SMS. A survey was conducted using items adopted from previous studies on social presence. 203 data points were collected and used for analysis. Across the whole sample, KakaoTalk is perceived as the highest in terms of perceived social presence level, followed by Facebook and SMS. Also, the users with higher level of sociality tends to reveal higher level of perceived social presence across all the media while younger and/or student users tend to maintain higher level of social presence perception across all the media. Further studies seem necessary investigating features of specific medium that may increase or decrease the perceived level of social presence.

본 작품은 학생들의 캡스톤디자인 작품이다. 현대인들은 자신의 감정을 특정한 문자를 통해서 상대방에게 전달하고자 한다. 하지만, 현재 모바일 폰의 문자 메시지는 텍스트 위주의 평범한 문자를 보내기 때문에 자신의 감정을 표현하기에는 불충분하다. 따라서 본 작품은 텍스트 기반의 문자 서비스를 탈피하여 편지지와 아이콘을 활용하여 지산의 감정을 표현할 수 있는 모바일 편지 서비스 앱이다. 본 작품은 바쁜 현대인의 특성상, 자신의 필체가 악필일 경우가 많아 꺼려하고 있다. 당장 자신의 글씨를 고치기에는 시간이 부족한 경우도 많고 동시다발적으로 메시지를 전하고 싶어 하는 사람들에게 항상 지니고 있는 스마트폰으로 자신의 진심이 느껴지고 특별한 편지를 제작 하여 전송을 하고자 개발하였다.

문자메시지를 작성하는 작업 특성과 사용자의 특성간의 상호작용의 결과로, 휴대전화 사용자 집단간 통화량과 문자메시지 사용량은 다르게 나타난다. 본 연구에서는 문장 입력시간을 기준으로 청년층과 중장년층 집단 간의 운지 속도를 비교하여 노화로 인한 운지 속도의 차이를 고려한 지적활동의 시간 차이를 알아보고자 하였다. 그리고 한글 문자 입력 과제의 수행을 반복하여 청년층과 중장년층의 입력 속도 변화를 비교하였다. 즉, 사용자가 충분한 연습을 거치면 연령층에 관계없이 문장 입력 시간이 비슷해질 수 있는지를 실험을 통해 확인하였다. 휴대전화의 문자 입력 시스템에 익숙하지 않은 청년층과 중장년층 각각 8명을 선발하였으며, 50ms단위로 입력시간을 측정하였다. 실험결과, 두 집단의 연습 이후의 성취한 문장입력 수행도는 유의한 차이가 있는 것으로 나타났다 (P=0.039). 이러한 결과는 노화로 인한 인지적 기능의 저하가 문자 입력의 속도를 저해하는 주요 요인임을 보여준다.

Analyzing characteristics of spam text messages had limitations since spam datasets are typically difficult to obtain publicly and previous studies focused on spam email. Although existing studies, such as through the use of spam e-mail characterization and utilization of data mining techniques, there are limitations that influence is limited to high spam detection techniques using a single word character. In this paper, we reveal the characteristics of the spam SMS based on experiment and analysis from different perspectives and propose coward analysis based spam SMS detection scheme with a publicly disclosed spam SMS from the University of Singapore. With the extensive performance evaluations, we show false positive and false negative of the proposed method is less than 2%.

Three types of Ad message convergence, A Letter, B Letter+Photo, C Letter+Photo+Video on the Facebook advertising were researched. For this research, three types of sample advertisements were tested on the 230 subjects. And the H1 - How do three types of advertisements differ on the SNS main trait, H2 - Among those Informativity, Reliablity, Playfulness, Intractivity as the SNS main trait, what is the more powerful factor on the brand attitude / Purchase Intention. For this research the ANOVA, Scheffe, Regression Analysis was used. As a result, H1 - The effect power of Playfulness and Interactivity on the three types of Ad message convergence ranked as "A

Individuals often receive smishing campaigns (mobile phishing messages), which they treat as spam. Thus, firms should understand how their customers distinguish their promotion messages from smishing. However, only a few studies examined this important issue. The present study employs the elaboration likelihood model to develop research hypotheses on the relationship between message cue and message credibility. The message cue in this study is classified as content cue, which is found in the content of promotion messages, and as leakage cue, which is found in peripheral information in the message. Leakage cue includes orthography (inclusion of special characters)and an abbreviated link sent by a faithless sender. We also propose that contextualization has a moderating effect on the relationship between content cue and credibility. We conducted a survey experiment to examine the effect of message cues on message credibility in the context of respondents receiving discount coupons through mobile messages. The result of data analysis based on 166 responses suggests that leakage cue had a negative effect on message credibility. A message with defective content cue has a marginally negative effect on message credibility. In particular, defective content cue in a high-contextual message has a strong negative impact on message credibility. This effect was not observed in low-contextual messages. Moreover, message credibility is significantly low regardless of the degree of contextualization if there is a leakage cue in the message. Our findings suggest that mobile promotion messages should be customized for message receivers and should have no leakage cues.

현 재난문자 서비스는 텍스트 기반의 재난경보 서비스 이다. 이 경우 한글에 익숙하지 않은 외국인 들은 제공받은 문자 메시지를 정확히 이해하기가 불가능하다. 이에 이미지 등 멀티미디어 정보를 제공함으로써 효과적인 재난경보 서비스를 실현할 수가 있다. 그러나 현 재난문사 서비스 방식은 멀티미디어 정보 전송에 적합하지 않다. 본 논문에서는 이러한 단점을 극복하고자 단말기에서 재난 이미지 표출을 위한 펌웨어 기반의 재난문자 서비스 방식을 제안한다. 이 방식을 위한 단말기는 재난 종류에 대응하는 이미지들을 미리 저장하고 있어야 한다. 또한 재난문자 메시지는 이미지 표출을 알려주는 특수문자를 사용한다. 이 방식은 신형 단말기에 장착되는 새로운 펌웨어를 이용하여 구현될 수 있다. 또한 본 논문은 이러한 방식이 기존 단말기와 충돌이 없음을 보여준다.

The study was conducted as a quasi-experimental study targeting 60 patients with ischemic heart disease to determine how the smoking cessation program that uses telephone counseling and text messaging (short message) affects smoking cessation self-efficacy, nicotine dependence, co levels, and smoking cessation rate of the first, second experimental group at varying times of arbitration and control group. An examination of the effects of this program revealed the control group to have a significant increase in smoking cessation self-efficacy, smoking cessation rate than the first and second group but a significant decrease in the nicotine dependence, co levels. In addition, although the control group showed a significant increase in smoking cessation self efficacy, smoking cessation rate and a significant decrease in co levels than other groups, there was no difference in nicotine dependence. Therefore, a smoking cessation program that uses telephone counseling and text messaging (short message) for patients with ischemic heart disease worked for the smoking cessation rate and appeared to be more effective, depending on the times of arbitration.

As financial transactions with a smartphone has become increasing, a myriad of security threats have emerged against smartphones. Among the many types of security threats, Smishing has evolved to be more sophisticated and diverse in design. Therefore, financial institutions have recommended that users doesn't install applications with setting of "Unknown sources" in the system settings menu and install application which detects Smishing. Unfortunately, these kind of methods come with their own limitations and they have not been very effective in handling Smishing. In this paper, we propose a systematic method to detect Smishing, in which the RIL(Radio Interface Layer) collects a text message received and then, checks if message databases stores text message in order to determine whether Smishing malware has been installed on the system. If found, a system call (also known as a hook) is used to block the outgoing text message generated by the malware. This scheme was found to be effective in preventing Smishing as found in our implementation.
