The purposes of this study were to explain consumer attitude, expenses and satisfaction of mobile-phone Users. The data of this study used from Pollever.com. This study was satisfaction of mobile-phone users in Korea. The users were consumers of Samsung, LG, SK-Telecom and Pantack. The critical success factor was on the subside for mobile-phone in the growth of mobile service, which we can analyze in its positive effects. Fifty percent of consumers were unsatisfaction with local companies without Samsung. Now most of local mobile-companies will developed music-phone, high-tec camera-phone, hi-slim phone, and health-phone. But, the results of this study are as fallow: Most of consumer' main issues were design, weight, and brand power. It was in that it played the driving force to upgrade the local mobile-phone services into international level with the explosive growth in business by providing cheap phones.

A mobile phone usage survey was administered to a nationwide sample of 3,617 adolescents. Major motivations of mobile phone usage were mobility/real-time connection, show off, information acquisition, entertainment, dialogue, schedule management, and advice. Maintenance of social relationship with the peer group was most important in mobile phone use. Motivations influenced mobile phone dependency : show off had the strongest influence on anxiety/paranoia followed by dialogue, entertainment, mobility/real-time connection. Without their phones, fashion-oriented adolescents showed mobile phone dependency and anxiety. Stronger dialogue and entertainment motivations were associated with weaker real time connection motivation and stronger paranoia symptoms. Mobile phone dependent adolescents had lower grades, showed lack of attention, had little dialogue with their parents and showed withdrawal from the peer group.

Smart Phone의 OS로 많이 사용하는 Android/Windows Mobile Smart Phone의 사용이 급격히 증가하고 있다. 무료 WiFi Zone과 인터넷 사용에 대한 취약점이 존재한다. Mobile Forensic의 증거 자료를 추출하는 방법은 SYN, JTAG, Revolving 방법이 있지만, 기존 휴대폰과 달리 Smart Phone은 OS와 구조, 사용방식과 기술의 차이로 인한 Mobile Forensic 연구 방법도 달라야 한다. 본 논문에서는 Smart Phone에서는 많이 사용되는 Windows Mobile/Android Smart Phone의 OS와 구조 차이를 분석한 데이터 백업과 스펙 분석 및 증거자료 분석을 한다. 또한 무료 WiFi Zone을 통한 인터넷 사용시에 취약점을 분석한다. 그리고 Android/Windows Mobile Smart Phone의 Forensic 자료를 생성하여 증거를 추출하고, Mobile Forensic 보고서를 생성한다. 본 연구를 통하여 Mobile Forensic의 기술 발전에 초석을 제공할 것이다.

이 연구는 이동전화에 대한 채널 정향, 면 대 면 커뮤니케이션의 회피 등 이용자들의 인적 속성이 이동전화 이용의 다양성, 이동전화의 적합성 거부감 그리고 이동전화를 통한 커뮤니케이션 네트워크에 미치는 영향을 살펴보려는 목적에서 출발했다. 대학생과 40대 이상의 그들의 가족들로 구성된 피조사자들을 대상으로 설문조사한 바를 분석한 결과, 응답자들은 이동전화에 대한 사회적 실재감과 친밀도가 높을수록 이동전화 서비스를 더욱 다양하게 이용하고 대인커뮤니케이션 매체로서 더욱 긍정적으로 평가하며, 이동전화에 대한 거부감도 더 작은 것으로 밝혀졌다. 아울러 면 대 면 커뮤니케이션이 원활하지 못한 사림들은 이동전화를 통한 대인커뮤니케이션 네트워크의 폭과 이동전화 이용량도 상대적으로 제한돼 있음을 알 수 있었다. 즉시성, 직접성, 이동성, 접근용이성 등 이동전화의 여러 가지 기술적 강점에도 불구하고 면 대 면 커뮤니케이션이 원만하지 못한 이용자들은 새로운 인간관계의 형성보다는 그들의 편협한 대인관계의 유지 강화에 이동전화를 주로 이용하고 있음을 이 연구결과는 보여주고 있다.

휴대폰 사용이 포화상태에 이르고, 최근 iPhone을 비롯한 Smart Phone의 사용이 급격히 증가하고 있다. 현재 휴대폰에서 포렌식 자료 추출하는 방법은 SYN, JTAG, Revolving 세가지 방법이 있다. 하지만 휴대폰과 Smart Phone의 기술과 사용방법의 차이로 인하여 포렌식 자료 추출 방법도 달라야 한다. 따라서 본 논문에서는 Smart Phone에서의 포렌식 자료 추출 방법을 연구하고자 한다. Smart Phone에서는 많이 사용되는 Google Android와 Windows Mobile Smart Phone의 분석을 위하여 스펙과 O.S. 분석, 데이터 분석을 한다. 또한 Google Android와 Windows Mobile Smart Phone의 포렌식 자료를 추출하여 증거자료를 생성한다. 본 연구를 통하여 실험된 기술 연구는 모바일 Smart Phone 포렌식 기술 발전에 기여할 것이다.

본 연구의 목적은 초등학생의 휴대전화 주요 용도인 가족연락용, 친구연락용, 개인오락용 수준이 휴대전화의 의존적 사용 정도와 우울에 어떠한 복합적인 구조적 영향을 미치는지 파악하는 것이다. 본 연구는 연구수행을 위하여 제3차 한국 아동 청소년 패널의 초등학교 6학년 1,996명 자료를 구조방정식 모형을 사용하여 분석하였다. 분석결과, 가족연락용 휴대전화 사용은 휴대전화 의존적 사용에 부(-)의 영향을, 친구연락용과 개인오락용 휴대전화 사용은 휴대전화 의존적 사용에 정(+)의 영향을 미쳤다. 또한, 휴대전화의 의존적 사용은 우울에 정(+)의 영향을 미쳤다. 휴대전화 의존적 사용은 가족연락용과 우울 간 관계를 부분매개하고, 친구연락용과 우울 간 관계 및 개인오락용과 우울 간 관계를 완전매개하는 것으로 나타났다.

As mobile phone has acquired a status of a fashion item expressing one's character, it is necessary to understand the fashion needs for this new fashion product. The purpose of this study was to apply the fashion orientation construct developed in the clothing research field to mobile phone and explore its validity. The multi-dimensional construct of fashion orientation which most widely represented the fashion aspects was examined for the two product categories of clothing and mobile phone. Data were collected from an online questionnaire survey, and a total of 1,136 responses were analyzed. The construct structure of fashion orientation of mobile phone resulted in individuality, innovation, and fashion was different from that of clothing extracted to interest/importance, fashion/innovation, and individuality. Fashion sensitivity and an early adoption of a new product were two different dimensions in mobile phone while not separable in clothing. Despite a higher predictability of the fashion/innovation orientation of clothing on fashion orientation rather than on innovation orientation of mobile phone, innovation orientation was more important to purchase behaviors of mobile phone. The study still implies that it is valid to use clothing fashion innovative consumers for mobile phone marketing.

The purpose of this study was to examine the effects of parental abuse and neglect, as well as that of children's peer attachment, on mobile phone dependency. Data were obtained from the Korean Child-Youth Panel Survey (KCYPS), and the participants were 1,892 (909 boys, 983 girls) elementary students (5th graders) who had a mobile phone. To measure the variables, this study used such scales as the parental abuse and neglect scale, peer attachment scale, and mobile phone dependency scale. The data were analyzed using descriptive statistics, Pearson's correlation, and structural equation modeling analysis. The results of the study were as follows: First, parental abuse and neglect had direct negative effects on children's peer attachment; that is, the more parental abuse and neglect, the less children's peer attachment. Second, parental abuse and neglect had direct positive effects on mobile phone dependency; that is, the more parental abuse and neglect, the greater children's mobile phone dependency. However, children's peer attachment did not directly affect mobile phone dependency; that is, children's peer attachment did not have a mediating effect between parental abuse and neglect, and mobile phone dependency. In conclusion, parental abuse and neglect influence children's peer attachment and mobile phone dependency. Thus this study showed that parental abuse and neglect, rather than children's peer attachment, affect children's mobile phone dependency.

The property of the mobile phone is taking important role to choose it. In the present situation, exploring, comparing and analyzing the important properties of regular mobile phone(feature phone) and smart phone are very meaningful study. Therefore, the survey was carried out to get the properties of feature phone and smart phone and analyze the difference of those phones. And proposed the important variables for customer satisfaction which must be given priority. The result showed that 'design' and 'Quality' are important to both mobile phone user groups. The problems with mobile phones currently in use were 'poor performance' to feature phone users and 'expensive charge' and 'poor A/S' to smart phone users. Two groups also showed significant difference with the customer satisfactions, and smart phone user group showed higher satisfaction. For smart phone user group, four factors are induced from the properties but 'Hardware Quality' (representing 'call Quality', 'A/S', 'Convenience to use', 'Battery life') and 'Design & Function'(representing 'Internet', 'Convergence Functions', 'Design, 'Color') have significant and positive effects on Customer Satisfaction.

Mobile phone is necessary articles by increasing mobile communication now. People usually use the Mobile phone in any time and place. Ring tone of Mobile phone effect owner or other person. The sound level of Mobile phone ring tone could be considered as noise if it is too loud a specific situation. Manufacturing company improve ring tone of mobile phone better in consumer's perception. In this study, we record ring tone of mobile phone and estimated the complexity and nonlinear characteristics of the relation between subjective evaluation and sound metrics. Linear regression models were obtained for the subjective evaluation and sound quality metrics. Semantic Differential Method is used to study sound quality Evaluation. To analyze the sound quality of ring tone.
