New media is rapidly changing with the recent development of the technology of transmitting, producing, editing, and sharing video information. This study investigates the effects of one person media broadcasting use motivation and social viewing on consumer attitudes toward brand, brand engagement, and purchase intention. It was fond that motives such as differentiation, social interaction with other viewers, mutual interaction with BJ, information-seeking, and new fun-seeking positively affected brand attitudes. Also, the same motives except fun-seeking positively affected brand engagement. Only mutual interaction with BJ and information-seeking were found to be positively related to purchase intention. Meanwhile, para-social relationships, social presence, and subjective norm positively influenced on brand attitudes and purchase intention each. Also, para-social relationships and social presence were positively related to brand engagement. Theoretical and practical implications, and suggestions for future studies are discussed in detail.

모바일 산업이 발달하면서 사람들은 개인간의 보다 섬세한 정보교환과 이로 인한 끈끈한 유대관계를 추구하게 되었다. 이러한 요구에 소셜 네트워킹 서비스 들이 단문 메시지 중심으로 활성화 되어 왔고, 스마트폰과 결합하면서 위치 정보를 추가하고자 하는 요구와 필요성이 문제시되고 있다. 그러나, 이러한 위치 정보는 민감한 정보이기 때문에 보안 및 프라이버시 문제가 대두되고 있다. 가족 구성원의 위치 정보를 공용 서버에 저장하는 것은 서비스 사용 활성화를 저해하는 요인이 될 수 있기 때문에, 본 논문에서는 가정내 홈 서버에서 사용할 수 있는 가정용 위치 정보 기반의 SNS 서비스를 제안하며, 사회의 가장 작은 구성 단위인 가정에서 가족 구성원들간의 친목과 유대관계를 증진시킬 수 있는 보다 공익적인 서비스를 제안하고자 한다.

The purpose of the research is to find out both what information tweens (12~14 years old adolescents) need and how they use YouTube to satisfy with their information needs. In order to achieve the goal, the research collected the data by conducting a survey on tweens (N=130) and analyzed the data with statistical processes. The research found out some significant results: first, tweens frequently use the informaton on YouTube and search for leisure information most often. Second, tweens search for information on YouTube because of ease and convenience on learning information even though they do not trust the information on YouTube. Third, tweens regard that YouTube play the role as a significant information source and searching tool, and use information on YouTube because the information on YouTube are composed of easy-to-understand video format. On the basis of the results, the research suggests and discusses how information organization such as public or school libraries provide information services for youth groups effectively.

Recently, we have been demanding the comfort of the indoor environment due to environmental problems such as fine dust and yellow dust. In addition it is pursuing the most pleasant indoor environment for humans. In this study, we designed and implemented monitoring systems and mobile applications to enable information such as room temperature and humidity. Open source software and open source hardware are required to design and implement the systems proposed in this study. In this study, the systems implemented used a bluetooth module, a light sensor, and a temperature and humidity sensor. In the future, we expect to be a basic study of systems that can operate dehumidifiers, warm-air fans, fans and humidifiers using motors and optimize indoor environment.

With the development of computer technology, many different kinds of digital design tools have been developed and used. In the circumstance, methodologies of digital process have more been researched. Despite various atypical forms, there have been limits to the application and practical use of the mobile technology for approaches to the creation of architectural forms and various circumstances. Therefore, this study tries to analyze previous studies and actual conditions of mobile application in order to recognize the research necessity and suggest the possibility of the atypical form creation in the mobile environment. In short, the purpose of this study is to recognize the necessity of the smart mobile application for making idea & learning tools, suggest the process based selective application method (not analytical application) of smart mobile application technology to make possible atypical form creation in the initial step of architectural design processes, and propose a new method of mobile application.

Although the rapid spread of mobile device like smart phone has increased, One of the main problems of systems is that they do not meet their quality requirements. Many researchers have tried to improve users' satisfaction and enhance their quality of life. The purpose of the study is to examine the moderating effect of lifestyle on the use of mobile internet service. To achieve our research purpose, we used lifestyle, IS success model and quality of life as the theoretical background. Based on the research model, we conducted survey and empirically analyzed the data. We classified user types according to lifestyle as a moderating variable. The results show that users' lifestyle can classify two group: curiosity-independent group and intelligence-pursuit of advanced fashion type. The impact of information and systems quality factors of mobile internet service on user satisfaction are differentiated from these lifestyle group. This paper ends with strategical implication of the study results.

Various other platforms have appeared due to the abolishment of WIPI requirement and increased problems related with hacking and security. Since levels consisting of these platforms are composed of various APIs (Application Programming Interfaces) which are not standardized, other ways must be considered to protect data which are transferred using XML formats. Therefore, XML encryption API and XML digital signature API for data protection and certification, which are both responsible to define mark-up languages for XML encryption and digital signature respectively, were designed in this paper. The simulation system which played the role of the server and client between two terminal units was realized to validate the APIs.

Now, smart phone markets are grows quickly. So it is needed research of CDN(Contents Delivery Network) technology for contents transmission in mobile networks. Especially the services of smart phone are focused on open platform model. So P2P(Peer to Peer) protocols will be used for mobile network because it is a distributed network architecture composed of participants that make a portion of their resources directly available to other network participants, without the need for a central server. Current research of P2P protocols for mobile network are not activated. The reason is appropriate in the mobile P2P network simulation environment, since it is not provided. So, in this paper we design a mobile P2P simulation system for CDN based on mobile P2P.

Recently, as mobile banking enables to instantly provide the customized service in accordance with customer demand via information technology. With this individual customized service, mobile banking plays a role of transforming the existing offline banking strategies. However, contrary to expectation, the mobile banking service has not been widely used to the extent that it can replace offline banking service. Therefore, the current study aims to explore the antecedents to affect customer's usage of mobile banking. Specifically, the antecedents influencing the intention to use and actual usage of mobile banking include personal-innovation fit, positive psychological capital, and service quality factors, which reflect the innovative technology characteristics of mobile banking. Furthermore, the paper also analyzes the effect of mobile banking service on intention to use and actual usage of mobile banking service. With empirical analysis using Structural Equation Modeling for 195 mobile banking users, the results showed that user's ability fit, value fit, and positive psychological capital positively affected user's future intention to use and actual usage of mobile banking. Furthermore, the current paper also found the significant moderation effect of usage purpose of mobile banking (banking task and online stock exchange) in the relationship between positive psychological capital and intention to use. This study suggests that banks need to develop mobile banking services that reflect customer's IT usability as well as their pursuing purpose and value.
