In the time of the Fourth Industrial Revolution, we endlessly cross between the virtual and the real in our daily routine. Information saving method has changed from physical to virtual and the contents of a digital device can be a method of showing one's identity. A digital device can be seen as a virtual version of a 'wuderkammer'. With this perspective, this study focuses on the changes that has occurred in our daily interaction, the process of thinking, perceiving, and understanding in the time of 'digital wunderkammer'. In order to discuss this matter, this study looks at the two art work series - 'Universal Addressability of Dumb Things' and 'UniAddDumThs' - by a British artist, Mark Leckey and analyzes the digital environment of today, its visual expression, and the characteristic of 'digital wunderkammer' reflected in his art works. Through this study, we hope that the readers can understand the paradigm shift of today and expand the creative possibilities in this new era of digital revolution.

This study discussed 'inclusive growth', which recently has gained attention as the 4th Industrial Revolution spreads, and considered innovative growth as a requirement for inclusive growth. Combining inclusiveness and innovativeness, a new concept of 'Digital New Deal' is suggested. Specifically, the new market creation strategy through digital transformation of existing industries and public sectors, and solving social problems were presented. It also analyzed problems of the past government-led top-down innovation drive and suggested the "Hybrid" approach as a new way of promoting digital New Deal. Finally, we looked at the 'job creation' effect, discussed the meaning of it in terms of inclusiveness and innovativeness, and proposed a policy alternatives to create lasting effects.

In the wake of the Arab Spring, the Internet's role in aiding dramatic political transformation has come to the fore. Throughout the Middle East, protestors have employed Facebook, Twitter, Youtube and other popular websites to organize and spread news at home and to the outside world. Chinese authorities have been increasingly nervous about the Arab uprisings, and fear that similar events will inspire unrest in China. The new information and communication technologies make it possible for social movements to initiate novel forms of collective actions. The Internet provides new opportunities for political liberalization. In Chinese society, citizens can now participate in politics uninvited. With each passing day, the online community gets stronger. The digital revolution has the potential for broadening democratic principles and could bring democracy to the collective Chinese mind.

A diesel Engine rotates vibratively because of alternative explosion strokes. Traditional measurement of a diesel engine speed is carried out by measuring output voltage of FV convertor from input signals of MPU(magnetic pickup unit) or of DC tachometer. Because these measurement include also vibrative rotation of a diesel engine, an analog filter is often used to eliminate high frequency noises due to periodic explosion stroke. But by this method these high frequency noises do not eliminated effectively because noise frequencies are changed according to diesel engine speed. In this paper, author proposes a new measurement method of a diesel engine revolution which read digital signal directly from MPU and prove the utility of proposed method through the real experiment.

Since the world entered the age called "Smart Revolution", there has also been a lot of changes in the field of education. In educational environment, there is a growing interest in smart learning based on mobile contents, with the development of Smart Devices and ubiquitous technology. This paper is about a research on what effects smart learning has on leaner side when learners make active use of mobile contents in this age of Smart Revolution. First, we embodied teaching plans for some practical classes in forms of mobile contents using M-bizmaker. After the learning process based on the embodied contents for students, we analyzed the survey results on 4 sections-their use of apps, screen composition, technical support, interactions. We also studied the results of a questionnaire on 4 sections-contents, information offering, feedback systems, learner assessment-to evaluate their satisfaction. The research suggests that learner satisfaction can be improved with smart learning based on mobile contents embodied for leaners.

Developments and changes in digital environment based on computer technologies and internet networks enabled us interactive communication for planning and execution through the freedom of 'connection', 'sharing', and 'conversion'. The subject of this study, interactive commercial, might be the core of success based on creation which stems from communication design, revolution in design and technology, and conversion. Communication in modern economy is not optional, but essential. Furthermore, like evolution process up to Augmented Reality from developments of mobile communication technology, or concept in paradigm change, digital interactive commercial means the core of success, not a part of it. Therefore, in order to achieve success in the global competition structure, mobile communication design, revolution, and creation which produce added value shall be working as a base. In order to reach effective communication process performance of interactive commercial media, this study would like to propose building a media commercial system which is realized by human senses. Using this, standardized methods for interactive commercial which can be used together with augmented reality based on digital technology, and for using digital robot contents are available, along with methodology system of their use. In addition, the ultimate goal of this study aims to discover new factors through reorganization of precedent analysis and adaptation based on academic achievement and practical application. And thus, it wants to contribute to practical use of interactive commercial out of augmented reality-based communication in which technology, marketing, and design are integrated to be used in real sense.
