From 2009, the market of smart devices has been rapidly increasing. These devices provide various services to users. The cloud messaging service, especially, is applied to many various services, and sends messages asynchronously. In the cloud messaging service, there are two methods for message transmission, message transmission based on an IP address and a publish/subscribe technique. Each technique uses basic messages in order to send messages to mobile devices. In this paper, the hybrid message transmission, based on user-customized analysis to reduce basic messages, is proposed. The hybrid message transmission uses Exponential Moving Average (EMA) and K-means algorithms for user-customized analysis, and determines the message transmission techniques in each timeslot.

이 연구는 MBTI의 심리 기능지표 조합인 ST, SF, NT, NF의 유형별 특징을 반영한 마케팅 문체 프레임워크를 정의하고 모델 학습을 통해 성격유형별 맞춤화 된 광고 메시지로 생성하는 것을 목적으로 한다. 활용되는 광고 메시지 자동 생성 기술은 BART 모델에 성격유형을 Prefix로 포함한 광고문을 학습시켜 성격유형에 따라 맞춤형 광고 메시지를 생성하는 방식이다. 학습된 모델은 Prefix 조작만으로 MBTI 성격유형별 문체 특징을 갖춘 광고 메시지로 변환되는 것을 실험을 통해 확인할 수 있었다. 본 연구는 성격유형의 특징을 문체 프레임워크로써 정의하고 이에 기반한 모델 학습을 통해 성격유형별 특징을 반영한 광고 메시지를 재현해 낼 수 있다는 점에서 의의가 있다. 또한 성격유형과 연관 feature를 함께 학습하여 유형별 문체 특징과 소구점을 포함한 광고 메시지를 생성했다는 기술적 가치가 있다. 이 연구 결과를 기반으로 차후 타겟 고객층의 성격유형과 광고 도메인을 고려한 효과적인 광고 콘텐츠를 생성해 내는 모델을 개발하여 타겟 마케팅 분야는 물론이고 지역별 또는 언어별 문체 간 차이를 구조화하거나 재현해야 하는 문제에서 기반이 되는 연구로 활용될 수 있을 것으로 기대된다.

본 논문에서는 사용자 위치 기반의 푸시 메시지 전달 기법을 제안한다. 제안한 기법은 푸시 메시지에 메시지 전달이 필요한 범위 정보를 내포하여, 메시지를 수신하는 모바일 장치가 사용자 위치에 기반을 두어 수신된 메시지가 적절한 메시지인지 판단한 후 디스플레이를 결정한다. 사용자 위치 기반의 푸시 메시지는 기존 사용자의 위치를 서버에 등록할 필요 없이 모바일 장치에서 사용자 위치를 판단함으로서 개인 정보를 보호하고 푸시 메시지를 사용자 위치에 기반하여 효과적으로 전달할 수 있다. 제안 기법의 응용 예로서는 위치기반 서비스 및 사용자 맞춤형 광고 서비스 등이 있다.

Personalized message syndication is an important process for maximizing the effect of mobile marketing. This paper proposes an algorithm for determining clients satisfying target conditions in real-time. The proxy server as an intermediate node stores client profiles (gender, age, location, etc) and their respective summaries into a database. When a company syndicates messages at run time, the proxy server maps target conditions expressed by boolean expressions to integer value and determines target clients by comparing target value with profile summary. Thus, this approach provides efficient personalized message syndication in very large systems with millions of clients because it can determine target clients in real-time and work with a traditional database easily.

우리나라는 현재 지상파 UHDTV 재난경보 방송서비스에 관한 연구를 진행 중에 있다. 한편, 노인, 장애인 등 재난취약계층은 재난 발생 시 최초 상황의 인지와 대응에 어려움을 겪어 일반 대중과의 재난 대응 격차는 커지고 있는 상황이다. 본 논문에서는 연구가 진행중인 지상파 UHDTV 재난경보 방송서비스를 기반으로 재난약자 그룹의 재난 상황 판단, 피난에 도움이 되는 맞춤형 미디어 전달이 가능한 재난메시지 확장 방안을 제안하며, 재난약자의 최적대피 및 대피형평성을 확보하기 위한 연구로 활용될 것을 기대한다.

In this study, we investigated which message provider is effective in a virtual reality (VR) environment for individuals with different needs with regard to affect (need for affect [NFA]) and cognition (need for cognition [NFC]). According to Haddock et al (2008), individuals with high NFA were more influenced to change their behavior by the emotional aspects of a message, whereas individuals with high NFC were more influenced by the cognitive aspects of the same message. We hypothesized that individual differences in needs could affect not only receipt of the message but also the acceptability of the message provider. For example, someone with high NFA might accept messages more easily from an acquaintance than from experts. In the VR environment, the appearance of the message provider could be manipulated in a way that makes him or her more familiar to the person receiving the message. Accordingly, in order to promote the effectiveness of message providers in a VR environment according to the individual difference in needs, we measured the level of the preference and self-efficacy according to needs (NFA or NFC), type of message provider (expert, significant other, or other), and VR device (text or VR). Contrary to what we expected, the results showed that there was no matching effect between the needs and the message provider. However, we found that level of preference and self-efficacy were significantly high when a VR device was worn only by participants with high NFA. This result suggests that a VR environment is more suitable for providing health advice to people with high NFA. In addition, the novelty of this study is that we tried to find the tailored message provider on health advice in VR environment and it is in the early stage of the research.

One important online marketing practice to emerge in recent years is online behavioral advertising. Online behavioral advertising entails a range of issues, including the following: personal information collection and usage agreements (three conditions: no agreement, agreement, or agreement with a reward), consumers' levels of perceived personalization (low vs. high), and consumers' level of online privacy concerns (low vs. high). The effects of all these is what this study is designed to examine, as it evaluates online behavioral advertising. Study findings suggest that types of information collection and usage agreement play a pivotal role in the evaluation of online behavioral ads. Individuals who provided the informed consent form with the possible reward had a more favorable attitude toward the brand than individuals who provided the informed consent form without a possible reward. In terms of personalization, the level of perceived personalization of the advertising message impacted consumers' attitudes toward the online behavioral ad and toward the brand. Finally, online privacy concerns appear to impact consumers' attitudes toward the online behavioral ad and toward the brand. Theoretical and practical implications are also discussed.

In smart healthcare service, the accurate and prompt emergency detection and notification are very critical to patients' lives. Since these detection and notification of emergency situation are usually performed by the medical staffs, it is difficult to simultaneously support many patients in real-time. This article presents a methodology for emergency bio-data transmission for smart healthcare using personalized emergency policy. It consists of three steps: In step 1, the bio-data is collected by wireless body area network. In step 2, the decision on emergency is made using personalized emergency policy. In step 3, the emergency message including the health condition information is converted between IEEE 11073 PHD message and HL7 CDA. By doing this, the emergency status of the individual bio-data collected from wireless body area network is detected automatically using personalized emergency policy. When the emergency is detected, the quick emergency rescue service can be provided to the patient by delivering to the emergency notification and the emergency bio-data. We have verified the service and functions of the proposed system architecture by realizing it.

In this Paper, we introduce an efficient on-line software service using an application customized graphic offloading library. The software service based on graphic offloading provides high-end software, like a 3D graphic design tool, as an on-line software service through using a client graphic rendering. When software is executed on server, its graphic works are handled by a client's GPU, while its data works are handled by a server's CPU. To improve the performance, we apply an asynchronous transmission channel scheme to our developed basic graphic offloading engine. Also, we add optimized common module and application specific module to our engine. To do that, we introduce how to implement the application specific module using analyzing patterns of graphic related APIs and messages that are generated by an executed software process. Also, we propose how to design the optimized common module using server side information caching. Finally, through the performance comparison experiment, we show that improved offloading engine has the better performance than old basic offloading engine.
