By the growing of SMS phishing victims, applications for processing spam messages are being released in succession. However most spam messages that cleverly modified the content like separating the consonants and vowels are fail to be filtered. In this paper, we implemented an application 'AntiSpam' which is able to identify spam strings in the text message to solve this problem. 'AntiSpam' searches spam strings in the text message by using set-based POI search algorithm, and then calculate the possibility of whether it is spam or not in accordance with the search results. In addition, it catches skillfully disguised spam messages in order to avoid missing the spam filtering. Users, who received a message, can check the result in spam message possibility decision result and the contents of the message and they can choose how to handling the message.

Variable message signs (VMS) are a useful tool for providing real-time traffic information to drivers. In particular, effective warning information provision leading to safer driving would be an important countermeasure to prevent traffic accidents. The purpose of this study was to identify users' preferences for traffic safety warning information formats. A variety of warning information scenarios using text and pictograms were devised and investigated for the purpose of selecting more effective methods to provide warning information. A portable variable message sign (PVMS) was used to evaluate users' preferences. The results of this study can be used for designing better warning information for the enhancement of traffic safety.

Examination of the concurrent evolution of communication tools and eating behaviors over recent decades reveals that social media and other forms of digital content have become powerful new driving forces for nutritional choices and food consumption. The purpose of this research was to examine the effect between goal orientation of message (promotion versus prevention) and the type of message (text versus image) on effectiveness of the message. The findings showed that individuals exposed to a promotion-focused message similarly responded to the message regardless of the type of the message. By contrast, those who exposed to a prevention-focused message showed significantly more positive responses to the message posted on the text-based social media than the message on the image-based social media. The findings indicated that, if presented effectively, social media could be harnessed to promote healthier eating habits and behaviors, prevent those which can be harmful, and ultimately improve an individual's daily food consumption and overall quality of life.

The purpose of this study was to reveal how the agility of fingers directly involved in the use of mobile phones, a necessity for modern people, is related to the amount of text usage. To find out, 95 people who agreed to the purpose of this research without any limitation on visual and upper-geometry were selected. The research period was from June 27, 2018 to July 31, 2018. The evaluation tool used in this study was Grooved Pegboard, a standardized evaluation tool that measures hand dexterity, and the general characteristics of examinees such as age, text message amount, and a hand that using for text messages were investigated through interviews. Since text input methods vary depending on mobile phone types, unfamiliar methods of typing mobile phone characters can affect the speed of texting. As a result, there were significant differences in hand dexterity between age and gender. The rate of texting and hand dexterity were statistically significantly faster than those in their 20s and 30s (p<0.05), and in gender, women showed significantly faster texting and hand dexterity than men (p<0.05). However, it was not statistically significant to text usage and to the dexterity of the hand.

Short message service (SMS) is one of the most important communication methods for people who use mobile phones. However, illegal advertising spam messages exploit people because they can be used without the need for friend registration. Recently, spam message filtering systems that use machine learning have been developed, but they have some disadvantages such as requiring many calculations. In this paper, we implemented a spam message filtering system using the set-based POI search algorithm and sentence similarity without servers. This algorithm can judge whether the input query is a spam message or not using only letter composition without any server computing. Therefore, we can filter the spam message although the input text message has been intentionally modified. We added a specific preprocessing option which aims to enable spam filtering. Based on the experimental results, we observe that our spam message filtering system shows better performance than the original set-based POI search algorithm. We evaluate the proposed system through extensive simulation. According to the simulation results, the proposed system can filter the text message and show high accuracy performance against the text message which cannot be filtered by the 3 major telecom companies.

인터넷의 등장은 세계를 초단위 정보 소통 영역으로 묶어 정보가 사회를 주도하는 형태로 발전시켰듯이, 미래 전쟁 양상도 정보가 전쟁의 승패를 결정하는 네트워크중심전(NCW)으로 발전되고 있으며, NCW의 핵심은 무기체계간 상호운용성이다. 무기체계간 상호운용성을 확보하기 위해서는 표준화된 정보를 활용해서 연동하는 중요하며, 우리 군은 무기체계간 연동을 위해 연동메시지인 KMTF를 활용하고 있다. 그러나 현 KMTF 표준은 메시지구조(message frame)만을 제시하고 세부적인 메시지는 정의하지 않아 각 체계 개발자가 나름대로 메시지를 정의함으로써 중복된 메시지를 각 체계별로 관리하고 있고, 동일한 메시지를 다른 방식으로 적용하는 부작용이 발생할 수 있으며, 체계간 연동을 위해 별도의 변환기를 개발해야 하는 문제점이 발생하고 있다. 이를 위해 본 논문에서는 첫째, 미군 메시지포맷인 USMTF를 벤치마킹하여 무기체계에 공통 적용이 가능한 공통메시지 설계방안을 제시하며, 둘째, 메시지 생명주기 관리 및 메시지 추가등록 절차 관리를 위한 KMTF 표준 관리 절차를 제시하고, 셋째, 개정된 메시지 규격에 맞는 KMTF 관리도구 개발의 방향을 제시한다.

In this paper, we propose a new text watermarking method using space coding and PN sequence. A PN sequence generated from user message modifies the space between words in each line. The detection can be done without original text image using the average space with in the text. Experimental results show that proposed method has the invisible property and robustness to the attack such as the elimination of words in the text.

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.
