디지털 ICT 기술이 우리 생활 곳곳에 스며들어 세상을 변화시키는 디지털 전환 시대를 맞이하여 조선 해양 분야도 예외는 아니어서, 최신의 ICT 기술이 융합되어 디지털 선박이나 e-navigation 및 GMDSS 현대화 과정 등이 진행되고 있다. 이러한 모든 조치들은 선박과 육상 간의 원활한 통신을 기반으로 하고 있으므로, 육상에서와 같은 대용량 고속통신을 보장할 수 있는 상시 접속 가능한 통신 채널이 확보되어야 하며, 특별한 별도의 단말기가 아닌 스마트폰으로서 선내 어느 곳에서나 제한 없는 통신 서비스를 제공 받을 수 있어야 할 것이다.

The purpose of this research is to further investigate the influence of partnership between with the mediator effect of the social business on the outcome of SCM. IT technology fusion electronic tags, mobile phone, such as cloud computing is also activated in supply chain management of recently, business is faster, if social business is applied here that are smarter, customers or suppliers, there may be communication directly and to further improve the relationship partnership. 150 questionnaires were sent to companies that have introduced SCM to their systems and are operating it. Among 150 questionnaires, 127 collected data were analyzed excluding incomplete 23 data. Statistical methods used in this study were frequency analysis, factor analysis, reliability analysis, t-test, ANOVA, path analysis, Scheffe test and Sobel test with Amos 18.0. and SPSS 21.0. The analytical results are as follows. First, the more the reliability, information share, continuous transaction, effects on the social business are getting higher, the interdependence has little impact on it. Second, the impact on the outcome of SCM, partnerships between companies, showed a significant influence the reliability, the share of information, the continuous transaction, but the interdependence was analysed as an uninfluential factor. Third, the social business is analyses to have a mediator effect in relationship between the partnership and the outcome of SCM.

Keen attention has been directed at "smart tourism cities" due to its role of solving urban problems arising from modern tourism development. However, some local governments are making huge investments in developing uniform tourism apps without specific directions or guidelines for the transformation of smart tourism cities. Accordingly, this study aims to develop a standardized and objective smart tourism competitiveness index and evaluate the competitiveness rankings of various cities around the world. The index comprises the five subindices of attractiveness, accessibility, digitalization readiness, sustainability, and co-partnership. The analysis results have shown that Singapore is the most competitive smart tourism city, followed by Amsterdam, New York City, Seoul and Barcelona, with Ho Chi Minh and Bangkok being relegated to the bottom of competitiveness rankings. We expect that this index can be employed as a global standard for continuously and systematically monitoring smart tourism city-related projects in the future.

This study focused on mobile trend in diffusion of smart phone. Presently, it has been evolved from digital nomad to smart nomad. Smart nomad era is based on digital technology with mobility and being smart. Smart nomad that is made up high-end device and intellectual content has changed structure of industry and life style. Smart phone is a core key in smart nomad era. In 2010 smart phone has been distributed about 2.5 hundreds million which is 20% of whole mobile phone sales and the volume of smart phone sales will be getting bigger and bigger in near future. Although, there are various reasons for success of smart phone market, this research focused 4 reasons: first, development of mobile device, second, evolution of mobile content distribution, third, support of government system, fourth, success of Docomo i-mode and Apple i phone. Smart phone will grow up more rapidly. Smart phone eco-system will be more competitive in the world. In Korea, smart phone eco-system also will be very competitive. For success in the middle of this competitive environment, Korea should lead the competitive phase with development of ability of creation software and content, construction of various partnership and evolution of next generation technology and service.

Based on the capabilities of smartphone cameras which have developed rapidly in recent decades, coupled with and the global market penetration rate, it will study the possibility of various international exchanges through smartphone filmmaking. This aims to achieve a civilian-oriented cultural exchange, instead of simply providing capital-oriented exchanges and film production education. The Smartphone Film Workshop was held as an auxiliary event of the Korea-Vietnam Film Festival, which ran from November 17 to 22, 2017. The three-day workshop, which took place within the festival period, drew attention for its international collaboration project between Korean film directors and Vietnamese film students. The researcher conducted practical-based research while participating as a mentor at this workshop. A step-by-step approach to the entire process of production and post-production was administered, including workshop team composition, scenario, and pre-production in Korea such as shooting equipment, schedule, completion of local works, and screening. Through an analysis of exchange cases at international workshops, we will use trial and error as ways to improve and consider the results of cultural exchanges and the effects of future expectations. Taking this empirical case study into account, we anticipate more active international exchanges through the smartphone workshops.

mankind has evolved to stand upright a million years ago. However entering an industrial society, much has changed in only a few decades. Human beings spend more time sitting down and working, which negatively affects their bodies. Leading medical studies have shown that the prolonged working conditions have significantly affected the causes of adult illnesses that we have known. Human beings have evolved in a moving direction. So, like modern societies, sitting or standing in one space for long periods of time without movement brings various side effects to the body. Reflecting this background, this study has led to think of work in an environment that is taking the evolutionary biology perspective from a traditional standing, standing work environment. They also plan to conduct an experiment to handle work with smartphones in the hopes of expanding their mobile office environment to use smartphones in the field, which is a type of smart work. The study could help build and establish a mobile office environment, a type of smart work. In addition to using smartphones, a working environment can be created that works by moving around. Furthermore, the paradigm of the work environment of businesses and students could be changed.

Linux has peculiarities of safety, flexibility, and open source. and Linux supports various hardware platforms. But because general Linux was designed for high performance H/W, Linux has several points to support for embedded system with limited resource. Specially, a main point is booting time that is spent to tens of second. In this paper, we purpose a fast booting scheme of Linux for Embedded System and estimate a performance of scheme purposed through realized prototype. Specially, to reduce booting time in environment of embedded system, we optimize boot loader, kernel and root file system. As a result, boot time reduce 28 second to 11 second in HBE-EMPOS II.
