Given the numbers of smartphones, tablets and other mobile devices shipped every day, more and more users are relying on the cloud as the main driver for satisfying their computing needs, whether it is data storage, applications or infrastructure. Mobile cloud computing is simply cloud computing in which at least some of the devices involved are mobile. Each node is owned by a different user and is likely to be mobile. Using mobile hardware for cloud computing has advantages over using traditional hardware. These advantage include computational access to multimedia and sensor data without the need for large network transfer, more efficient access to data stored on other mobile devices and distributed ownership and maintenance of hardware. It is important to predict job execution time in mobile cloud computing because there are many mobile nodes with different capabilities. This paper analyzes the job execution time for mobile cloud computing in terms of network environment and heterogeneous mobile nodes using a mathematical model.

Korean mobile communications industry has been a main locomotive of the drastic development of Korean IT industry and became one of core industries in national economy. To secure strong competitiveness of mobile communications industry, smooth cooperation should be reconsidered among government, universities, research institutions, and private companies. Future mobile communications technology will be evolved from IMT-2000 to system upgrade, 3.5G and 4G. And the goals of technology development are provision of mobile multimedia services based on better mobility and higher data speed rates. Therefore, Korea's technology development strategies of mobile communications should be focused on intensifying bondage of international cooperation, strengthening standardization activities, and enhancing core technology development capability to secure IPR.

Mobile communication industry is attracting a lot of attention all over the world and is expected to continue developing endlessly with the current rapid development of IT industry. Nowadays, mobile communication companies of vietnam are competing about service quality in order to retain existing customers and improve customer satisfaction and customer loyalty. This study attempts to research about the effect of mobile communication service quality on customer satisfaction and affecting relationship between customers satisfaction and customer loyalty. In this research empirically examine how mobile communication service quality influence customer loyalty in Vietnam. To do this, after considering characteristics of mobile communication service quality, quality measurement instrument was designed including call quality, call charge, cellphone, added service quality, corporate image, employee's attitude, and behavior. The study finds that all factors of call quality, added servces quality, corporate image, employee's attitude and behavior have positive effect on customer satisfaction except call charge and customers satisfaction also effects customers loyalty positively. From these results, Vietnam domestic mobile communication companies and foreign companies can grasp the general information about Vietnam mobile communication industry, and then, establish customers satisfaction strategies more effectively.

The purpose of this study is to analyze the relationship between customer value and trust and the effect of trust on loyalty in the field of mobile entertainment. As smartphone use becomes more popular, the mobile business is growing rapidly. In particular, the mobile entertainment industry, such as mobile games and mobile video, is growing faster. This study was based on the main survey had conducted from 25th September 2019 to 7th October 2019 by 300 users who had experienced mobile entertainment applications in the past. Statistical analysis was performed by using the IBM SPSS v.22.0. The analysis results are as follows. First, the utility and quality of utilitarian value, enjoyment and aesthetics of hedonic value, and status enhancing of social value have significantly positive influence on trust. Second, privacy risk of social value have significantly negative influence on trust. Finally, trust has significantly positive influence on loyalty. Based on the results, we discussed the implications for the successful operation of mobile entertainment.

A study on the sustainability evaluation of the requirements of the mobile industry closely related to the human factor was needed. We conducted the sustainability evaluation of the mobile industry using a quantitative evaluation method with the AHP tool and a qualitative evaluation method reflecting the technological age flow of the philosophical thoughts to improve the reliability of the evaluation results of the model verification. And this evaluation is to evaluate the consistency of the connection between the national sustainability and the mobile industry. In order to draw the conclusion of the relevance, the team member Delphi 5-point scale was used. As a result, the priority was confirmed in the national sustainable development indicator and mobile industry indicator. Quantitative and qualitative evaluation was applied to the discontinued model of mobile to derive insufficient indicators, and it was confirmed that if the indicators were improved and reflected, it would be sustainable. And in order to secure reliability and accuracy, we made a proposal to apply the systems engineering process to the development of the model evaluation field. The systems engineering technology process meets the needs and requirements of stakeholders throughout the lifecycle and it is suitable for the development model of the industry's sustainability assessment.

Mobile network infrastructure is being completed with the development of hardware and software for mobile devices. Network in mobile devices has evolved for telematics that is expanded much more than its existing concept. Telematics is compound word that is formed from the words "telecommunication" and "informatics". It means that telematics performs control and monitoring service with using mobile device resources. These services provide their services for users' requests through wired or wireless network from mobile devices and server that offers contents and network service collects management information of mobile devices. Map service is one of the preferred services for many telematics users. However, mobile map service has a limit between traffic and information sharing. Therefore it is very important to supply their information for both service provider and terminal user. In this paper, we design a new interactive sketch map using routes and information on the space to be applied effectively, and provide an extended document format that is defined to an extensible and dynamic clustering scheme to have portability map service for mobile device.

모바일 환경의 특수성을 중심으로 다양한 컨텐츠를 적용한 모바일 광고가 활성화되고 있다. 상품뿐만 아니라 도시마케팅 측면에서도 전통적인 광고의 한계를 벗어난 광고전략이 필요하다. 하지만, 지역에서의 관련 광고는 주로 산업육성 차원에서 이루어지고 있다. 따라서 지역산업을 통한 상품의 유통을 위해서도 지역에 대한 도시마케팅을 통해 산업과의 연계가 시급한 실정이다. 본 연구에서는 모바일 광고특성이 도시브랜드에 대한 경험과 감정을 구축해나가는 과정을 통해 도시 마케팅 정책 방향을 제시하고자 한다. 이를 위해 모바일 광고를 지역에서 전략적으로 이용하기 위해 모바일 광고특성을 선정하고, 제주의 도시브랜드 경험과 도시브랜드 감정에 대한 영향을 살펴보았다. 또한 모바일 광고와의 커뮤니케이션 경험의 조절효과를 확인했다. 연구의 결과는 제주의 도시마케팅을 위한 광고의 정책적 방향성을 제시하는데 기여할 수 있을 것이다.

모바일의 확산으로 인한 게임 산업에서의 유통구조의 변화와 패러다임의 변화가 크게 일어나고 있다. 전통적인 게임의 유통 구조를 탈피하여 앱마켓이란 새로운 보급 방법은 기존의 게임 산업에 대한 대체 또는 위협 요인으로 작용하고 있다. 모바일 게임의 이동성은 가장 큰 장점이라 할 수 있지만 모바일 게임은 컴퓨터 및 다른 디바이스를 이용한 게임에 비해 조작이 용이하고 간편하고 쉽다는 특성을 가지고 있다. 이러한 점에서 본 연구에서는 가장 인기를 모은 모바일 게임의 특성을 게임 유형별로 알아보고자 한다.
