스마트폰은 3R(Real time, Reach, Reality)을 통해 개인 기업 사회를 변화시킬 것이다. '언제 어디서나' 인터넷으로 무한한 정보를 이용할 수 있고 메신저, 인터넷 커뮤니티 사이트 상시 접속 등을 통해 실시간 커뮤니케이션을 수행하는 '속도의 경제'가 가속화 될 것이다. 특히 ICT 기술은 여성의 사회진출과 경쟁력을 증가시켜 여성주도 시대의 도래를 앞당기는 데 기여할 것으로 전국 여자대학교의 ICT개설 교과목의 파악 및 분석을 통해 향후 여성과 고령자의 편의를 위한 ICT 교과목 개발에 일조하고자 한다.

최근 무료 WiFi Zone이 확대되고 있고, Smart Phone으로 무료 WiFi에 접속하여 인터넷으로 접속하여 메신저를 하거나, 메일확인, 정보검색 등을 한다. 하지만 무료 WiFi Zone에서 Smart Phone으로 인터넷을 할 때, 개인정보를 해킹 당 할 수가 있다. 본 논문에서 안드로이드 O,S, Smart Phone에서 무료 WiFi를 이용하여 접속한다. 먼저 메신저와 웹사이트 로그인을 한다. 이때 AirPcap을 이용하여 패킷을 캡처한다. Packet 분석 툴인 WireShark를 사용하여 Packet의 내용을 분석하고, ID, PW와 메신저 대화 내용을 해킹한다. 해킹한 개인정보 ID, 비밀번호를 이용하여 인터넷 사이트에 접속을 하여 관리자 권한을 획득한다. 그리고 Smart Phone에서 WiFi접속 시 공격에 대한 보안대책을 제시한다. 본 연구는 Smart Phone에서 무료 WiFi 접속 때, 보안성 강화연구와 무선 해킹과 방어 기술 발전에 초석이 될 것이다.

The demand for messenger service goes on growing rapidly with widespread use of smartphones. Generally, the smartphone messenger provides group communication functions in which users can make the group and communicate with each other. In the mobile meeting, the attendees can participate in the meeting with use of smartphone messengers wherever they are. To make the mobile meeting put to practical use, the mobility and privacy should be ensured to attendees. To satisfy the mobility requirement, the user which is not belong to the group members should not be able to participate in the meeting. To ensure the privacy requirement, the attendees should have not to repudiate the meeting results. In this study, the mobile meeting authentication scheme is proposed which provides mobility and privacy. The proposed scheme consists of meeting group creation, group key generation, group signature and verification protocols. All attendees should have to participate in the signature verification because it is based on the challenge-response type protocol. Thus, it's not possible to collude with malicious attendees to change the meeting results.

현대 사회에서 대부분의 사람들이 SNS 어플리케이션을 선호하고 자주 이용하고 있다. 그 동안 삐삐, 휴대폰, 문자, 싸이월드&메신저 등 커뮤니케이션의 도구가 진화해왔으나 점차적으로 단순화를 추구하는 경향이 증가하고 있다. 또한, 인터넷을 이용한 인간관계가 대중화되면서 삶을 살아가는데 있어 SNS(Social Networking Service)는 매우 중요한 요소가 되고 있다. 따라서 본 논문에서는 현대 사회에서 SNS에 열광하는 이유와 SNS의 사용목적, 선호도 등을 설문 방식의 적용으로 조사, 분석하는 연구를 수행하였다.

The communication via MIM(Mobile Instant Messenger) has unique characteristics; one of them is use of emoticons. Although using emoticons in MIM is getting a lot of attention from business fields and emoticons markets in MIM is growing rapidly, there are little researches focused on emoticons in MIM in consumer behaviors and marketing area. So, the purpose of this study is to fill this theoretical and practical gap. For this purpose, we explore the effect of and trust in MIM system and attitude toward use of emoticons on purchase intention to emotions in MIM. Our study used structural equation modeling analysis; the results showed that perceived benefits and perceived risk to MIM affected trust in MIM system significantly, more specifically, while perceived benefits affected trust in MIM system positively, perceived risk affected trust in MIM system negatively. We also found that perceived usefulness of emoticon in MIM and flow experience influenced attitude toward use of emoticons positively. Lastly, trust in MIM system and attitude toward use of emoticons had positive effect on purchase intention to emoticons in MIM. The implication and limitations of this study are also discussed.

The purpose of this study is to explore the fundamental nature and meanings of the experiences of university students with regard to their smartphone usage in order to prevent smartphone addiction and provide guidelines to develop effective interventions. Nine university students who were currently enrolled in an university located in a Korean province participated in this study. In-depth interviews were conducted from June of 2012 to July of 2012, and data were analyzed using Colaizzi's phenomenological qualitative method. As a results, five theme and 40 subthemes of experiences of problematic smartphone usage were identified. Those themes include 1) a desperate try to connect with others(exposing oneself without appropriate self-protection, seeking emotional comfort, hurt and mistrust); 2) excessive use of smartphone and loss of self-control(more smartphone usage over computer/over-immersion/excessive usage/habituation, loss of self-control); 3) psychological difficulties(excessive attachment and dependence, separation anxiety, clingingness, reduced patience) ; 4) threats to daily functioning (changes in priorities, regressed independent daily functioning, irregular daily patterns, health problems, interruptions from free messenger, academic difficulties); 5) potential for recovery(conflictual feelings and doubts over smartphone usage, importance of interpersonal(face-to-face) communications, willingness to cut down the use, hope for recovery). This study provided suggestions for the prevention effort against smartphone addiction.

Smart phones become popular all over the world recently. At the same time, demand of various additional services, such as SNS by utilizing low-cost reliable Wi-Fi network and position information, is expected to keep growing. In this paper, Implementation of SNS based on an Open Wi-Fi & Position Information was proposed. This service is achieved by constructing an Open Wi-Fi network based on a built AP access information database. And in order to provide durable connection in mobile environment, RSS detect AP switching module and mobile IP are utilized in the proposed service. Furthermore, with the utilization of GPS information of AP, AP providers could delivery various information such as advertisements, promotion events. In addition, it is possible for AP users to communicate with each other, thus a position information based SNS was also proposed in this paper.

This study aims to examine how mobile instant messenger (MIM) usage pattern and MIM intensity influence MIM users' social capital. Total 253 MIM users in their 20's and 30's participated an online survey. Results showed that MIM frequency and network size affected bonding social capital. Meanwhile, MIM intensity was the only variable that influenced users' bridging social capital. Overall, the strength of strong ties in mobile media use was confirmed again. It was also confirmed that measuring the qualitative level of emotional attachment to the MIM (MIM intensity) was more important than gauging mere usage pattern when evaluating social capital enhancement through mobile media use.
