The main obstacles for adopting a mobile health information system to existing hospital information system are the redundancy of clinical data and the additional workload for implementing the new system. To obtain a seamless communication and to reduce the workload of implementation, an easy and simple implementation strategy is required. We propose a mobile clinical information system (MobileMed) which is specially designed for the easy implementation. The key elements of MobileMed are a smart interface, an HL7 message server, a central clinical database (CCDB), and a web server. The smart interface module transfers the key information to the HL7 message server as new clinical tests data is recorded in the existing laboratory information system. The HL7 message server generates the HL7 messages and sends them to the CCDS. As a central database the CCDS collects the HL7 messages and presents them to the various mobile devices such as PDA. Through this study we might conclude that the architecture for the mobile system will be efficient for real-time data communication, and the specially designed interface will be an easy tool for implementing the mobile clinical information system.

We analyze the performance of multistage cooperation in decode-and-forward relay networks where the transmission between source and destination takes place in $T{\geq}2$ equal duration and orthogonal time phases with the help of relays. The source transmits only in the first time phase. All relays that can decode the source's transmission forward the source's message to the destination in the second time phase, using a space-time code. During subsequent time phases, the relays that have successfully decoded the source message using information from all previous transmitting relays, transmit the space-time coded symbols for the source's message. The non-decoding relays keep accumulating information and transmit in the later stages when they are able to decode. This process continues for T cooperation phases. We develop and analyze the outage probability of multistage cooperation protocol under orthogonal relaying. Through analytical results, we obtain the near-optimal placement strategy for relays that gives the best performance when compared with most other candidate relay location strategies of interest. For different relay network topologies, we also investigate an interesting tradeoff between an increased SNR and decreased spectral efficiency as the number of cooperation stages is increased. It is also shown that the largest multistage cooperation gain is obtained in the low and moderate SNR regime.

Impulse buying occurs when consumers feel an urge to impulsively buy a product without thoughtful consideration of why and for what reason they need the product. However, few efforts have been made to identify the impacts of perceived scarcity on the impulse buying of fashion products in mobile shopping malls. This study's objectives were to estimate, using structural equation model analysis, the impact of a scarcity message on browsing, feeling the urge to buy, and impulse buying of fashion products on mobile shopping malls. Data was collected from 206 customers who experienced to impulse buying fashion products via objective sampling. Structural equation modeling was used to test the hypotheses developed for the study. Results found evident effects of the scarcity message on the impulse buying of fashion products directly and indirectly. Additionally, consumers felt the urge to buy had a significant impact on the impulse buying of fashion products, whereas browsing had little impact on the impulse buying of fashion products. This is an expanded study to examine structural equation modeling of impulse buying of fashion products on mobile shopping malls. These results will contribute to a better understanding of the mechanisms that underlie the operation of an effective scarcity strategy for fashion products on mobile shopping malls.

At present, various technologies are rapidly advancing, centering on the concept of virtuality. From the technology of virtual reality, which allows us to experience the senses as if they existed, to the technology of augmented reality, which provides new information or services based on reality, they are no longer strange things for ourselves because we experience them every day and night. Even though the concept of virtual is very familiar in terms of technology, it is not known how individuals accept the concept of virtuality, how they change our way of thinking, and how their behavior changes. This study aims to approach virtuality perceived by the individual from the viewpoint of individual's information processing. Virtuality is defined as the degree to which the situation facing an individual is far from actual reality. An individual can judge the degree of virtuality easily, which is considered to be a psychological distance which is an important factor in personal information processing. In this study, we have confirmed whether the argument is applied to the real world in the context of advertisement. According to the construal level theory, when an individual feels virtuality at a high level, the individual thinks that the situation they are facing is psychologically distant and accordingly has a high level construal. Therefore, it is more influenced by 'advertisement emphasizing symbolic appeal' which is matching with higher level. On the other hand, when an individual feels a low level of virtuality, the individual thinks that the situation they are facing is psychologically near and thus has a low level construal. Therefore, respondents are more sensitive to functional appeal, which is related to lower level. This study has the theoretical contribution in terms that the degree of virtuality affects the psychological distance of the individual. In addition, the results of this study have practical contribution in terms of being able to be actively used in the information delivery strategy centered on the advertisement.

This paper examines communication patterns of key Twitter users by considering the socially and politically controversial Sejong City issue in South Korea. The network and message data were drawn from twtkr.com. Social network-based indicators and visualization methods were used to analyze political discourse among key Twitter users over time and illustrate various types of Tweets by these users and the interconnection between these key users. In addition, the study examines general Twitter users' participation in the discussion on the issue. The results indicate that some Twitter profiles of media outlets tend to be very dominant in terms of their message output, whereas their Tweets are not likely to be circulated by other users. Noteworthy is that Twitter profiles of individuals who are geographically affiliated with the issue are likely to play an important role in the flow of communication.

LINE, an instant message App with a powerful capability of transmitting various forms of data, has been overwhelmed in Asia since launched in 2011. Due to its popularity, LINE was first used in the 2016 Taiwanese presidential election. This research utilized a functional approach of campaign communication discourse and political visual images to analyze how candidates managed and presented themselves by textual and visual information on LINE. Regarding the textual information, results revealed their strategy inclined to reverse gender stereotype because the female candidate emphasized policy over character, while the male emphasized character over policy. Both candidates did not fully employ ten image functions because they utilized mostly the emotional and image building functions. The female candidate message achieved the largest total amount of 'like' and 'share'. This study probes into the App campaigning and improve the feasibility and practicability to share knowledge of political communication by new media.

공익광고는 전체 구성원의 동의를 계획적이고 목표 지향적인 방법으로 얻어내어 궁극적으로 사회변화를 추구한다는 점에서 전략과 기술이 포함된 종합적 마케팅 개념이다. 상업성이 배제된 공익광고는 사회적 문제를 중심으로 제작되기 때문에 그 사회의 흐름과 의제를 잘 반영하고 있다. 아울러 공익광고는 현재의 문화적 가치를 광고 메시지에 투영시킬 뿐 아니라 미래의 문화가치를 만들어내는 역할을 동시에 수행한다고 볼 수 있다. 이러한 관점에서 우리나라 공익광고의 텍스트에 대하여 분석 해 보는 작업은 지금까지의 공익광고의 커뮤니케이션전략의 틀을 파악해 보고, 앞으로 효율적인 광고 집행을 위한 계획수립을 위하여 의미 있는 연구라고 할 수 있다. 본 연구는 실제 제작, 방영된 TV '환경보전' 공익광고물을 대상으로 하여 영상이미지와 언어에 관한 내용분석을 실시하여 TV 공익광고 텍스트에 내재되어 있는 시각적 이미지와 언어적 요소에 관하여 분석해 봄으로서 공익광고의 특성을 밝혀보고자 하였다. 연구의 결과로는 1980년대의 환경관련 공익광고는 언어중심의 설득적 메시지를 중심으로 하고 시각적 요소는 그에 대한 대응물로서 작용하고 있으며 수용자를 교육, 계몽하고자하는 의도를 나타내고 있었다. 이러한 이유로 주인공과 스토리 라인이 없는 비서사적 특성을 잘 보여주고 있었다. 이에 비해 1990년대 이후의 공익광고는 탈언어적인 이미지 중심으로 구성되어 있으며 은유적 기법을 사용한 시각적 구성을 통해 수용자의 판단과 개입을 활성화, 공익 캠페인의 효과를 극대화하고 있다. 또한 서사 내적 구성으로 공익광고에서 전달하고자 하는 주장을 시각적 방법을 통해 이야기 형식으로 제시함으로써 수용자의 관심제고와 설득에 기여하고 있는 것을 알 수 있었다. 이러한 영상이미지와 언어의 관계에 대한 연구의 결과는 오늘날 광고를 포함한 모든 영상제작물에서 공통적으로 볼 수 있는 시대적 경향으로, 공익광고 캠페인의 새로운 방향을 제시할 수 있는 주목할 만한 결과라고 할 수 있다.
