Storytelling which is part of human nature, has changed over millions of years. The development of technology and media has shaped Storytelling into various forms and shapes, and due to the recent spread of smart devices, the influence of interactive storytelling has grown significantly. The technology which allows diverse and natural input of users, have transformed the listener to user and has allowed the user to 'experience' the story rather than 'hear' it. In line with the trend in the development of these technologies, this study seeks to design and implement an interactive tale for children on an ipad platform. Focusing on the interaction aspect, this story is designed mainly for 3-7 years olds, which contains various multimedia elements and interaction elements that use built in technology such as multi-touch technology and microphone technology to allow user input that aline with the context of story. Focusing on children's experience and empathy with the characters of the story, 'Three Little Pigs and the Wolf' contains 22 steps and was published in the itunes Store.

애플의 태블릿PC 브랜드 명인 "아이패드(IPAD)". 전 세계 태블릿PC 시장을 새롭게 만들어 냈을 뿐만 아니라, 전세계 태블릿 시장의 60% 이상을 석권하고 있는 제품이다. 그런데, 이 대단한 제품이 중국에서는 그 상표권을 중국 업체에 선점당하여 판매금지를 당할 위기에 처해있다. 애플은 중국 IPAD 상표권을 양도 받았다고 주장하지만, 중국 법원은 이미 1심에서 중국의 션전 프로뷰사의 손을 들어주었다. 피해금액만도 천문학적인 액수가 될 것으로 전망되는 이 상표분쟁은 도대체 어떻게 시작되었으며, 무엇이 문제가 되고 있는지, 사건의 처음부터 현재까지 상세하게 살펴보자.

In this study, a digital textbook was developed for effective career and vocational education of students with disabilities. The contents of developed digital textbook consisted of 'lesson 15: Sale(1)' of middle school career and vocational education of basic curriculum. It progresses six periods and each topic activities are composed of open learning, learning activity 1, learning activity 2, and organized learning in order. NamoPubTreeEditor Program was used to develop the text book in the study, digital textbooks were designed to be compatible with various devices including smartphone of android operating system, Tablet PC, the iOS system, iphone, ipad, etc. In addition, it was designed to offer a variety of learning materials such as sale multimedia materials, glossary, evaluation questions, and linked data related to sale, supported self-motivated learning. allowed students to evaluate their study for the learning of students with disabilities.

When people stands near someone's mobile device, it can easily be seen by others. To rephrase this, attackers use human psychology to earn personal information or credit information or other. People are exposed by social engineering attacks. It is certain that we need more than just recommendation for the security to avoid social engineering attacks. This is why I proposed this paper. In this paper, I proposed an authentication technique using NFC and Hash function to stand against social engineering attack. Proposed technique result is showing that it could prevent shoulder surfing, touch event information, spyware attack using screen capture and smudge attack which relies on detecting the oily smudges left behind by user's fingers. Besides smart phone, IPad, Galaxy tab, Galaxy note and more mobile devices has released and releasing. And also, these mobile devices usage rate is increasing widely. We need to attend these matters and study in depth.

The outbreak of the novel coronavirus disease in 2020 caused a global semiconductor supply shortage and disruption in the production of devices such as iPhones owing to China's quarantine lockdown. Thus, Apple is diversifying its production bases from China to countries like India and Vietnam. The company is also accelerating semiconductor development to guarantee a stable supply, reduce design costs, and customize semiconductors with high quality and outstanding specifications for their products to outperform devices that use general-purpose semiconductors. Following the mobile application processor, Apple is releasing world-class semiconductors, such as the M1 and M2 chips that play the role of central processing units.

Mobile devices like iphone, ipad, kindle, and PDA are used as everyday tool. In the mobile environment, smart phones and other mobile units are also used as a tool for protection or infringement of personal information. Therefore, smart monitoring technology is required to protect personal information and privacy. On the other hand, with smart phones and the mobile environment, diverse application technologies are realized on hardware and software platforms. Therefore, this paper designs the network structure that forms privacy trust zone, and based on this, deals with the monitoring and monitoring prevention system with a focus on CCTV, through which this paper proposes a system that provides privacy trust zone information and its utilization which is capable of smart monitoring.

Many e-book readers have become available as e-books are in popular use these days. We first developed the evaluation criteria and elements for testing the usability of e-book readers and then examined the usability of three e-book readers. The usability testing was conducted using three e-book readers that were most popular with 15 participants that consisted of middle school students, university students, and office workers. The study found that iPad showed the best usability. In case of Amazon Kindle, participants indicated that the lack of the touch function imposed a great deal of negative impact on the usability of the interface. Also, the hardware- and software-oriented usability provided by an e-book reader was considered to be a very important element for the users, and the portability in connection with the hardware-oriented aspect of an e-book reader was shown to be of great effect to the overall usability of an e-book reader.

3D TV was been able to see in the market in early in this year. Tablet PC such as ipad by Apple and Galaxytab by Samsung were introduced recently. Those are possible by developing H/W and S/W of computer technology. The needs of interactive contents in many areas including education and entertainment area are increasing rapidly according to the various information devices are or will be in the market. Fore the more, GoogleTV and AppleTV are compete each other to dominate the world market in advance recently. CookTV tries to dominate in the domestic market by upgrading the current system. Diverse information devices are in the market means various size of displayers are able to be shown in our life. As TV is fused to computer, the displayer is substituted to TV's screen and the trend of TV is became bigger. The evolved TV is able to replace the computer by connecting to the network and people want to do interactions with contents by using the bidirectional communication. Therefore, it is expected to changing the human lifestyle. It is natural that contents for all members of family are needed, since TV's screen become bigger. It is required that the contents should guarantees the accessability of information to the all of family members and the easy interaction with contents. Our goal of experiment are to analyse the influence of interaction with contents as the size of images and to analyse a learning effect of contents quantitatively by applying a statistical method. Users interacted with contents without any difficulty when they met a same dimension and shape of objects as ame dimension and shape objects in their experiences or learning, was confirmed. And the learning effect were analysed and explained by applying the correlation.

Based on the case study methods, the study analyzes emergence and ensuing typology of global ebook platforms such as Google eBook, Amazon Kindle, iBooks Store. Global ebook platforms show adaptation process responding to rapidly changing digital technological envirment and it's fitness landscape. The critical elements in its emerging process are the distinct selection criteria, the degree of resource abundance and the search process based on open innovation. Based on these critical elements, the global platforms show speciation process, so called niche creation and are evolving into a variety of the typology based on the initial condition of key resource which makes the platform emerge and grow. Each global ebook platforms is evolving into open platform, hybrid platform, closed platform. Google eBook has openness and extensibility due to a variety of devices based on Android and a direct involvement of actors. Amazon Kindle has developed from a online bookstore and into the hybrid platform which have not only closed quality but also openness with ebook devices and mobile network. iBooks Store has developed into the closed platform through the agency model based on competitive hardwares and closed quality with iphone and ipad.
