This paper presents a programmable System-On-a-chip (SoC) for various embedded smart applications that need Neural Network computations. The system is fully implemented into a prototyping platform based on Field Programmable Gate Array (FPGA). The SoC consists of an embedded processor core and a reconfigurable hardware accelerator for neural computations. The performance of the SoC is evaluated using a real image processing application, an optical character recognition (OCR) system.

This paper deals with sensing ability of smart sensor that has a sensing ability to distinguish materials according to surface types of smart sensor. We have developed a new signal processing method that can distinguish among different materials. The smart sensor was developed for recognition of materials. We made two types of smart sensors in our experiment. Then, we estimated the ability to recognize objects according to smart sensor type. We estimated the sensing ability of smart sensor with the $R_{SAI}$ method. Experiments and analysis were executed to estimate the ability to recognize objects according to surface types of smart sensor. Sensing ability of smart sensors was evaluated relatively through a new $R_{SAI}$ method. Applications of smart sensors are for finding abnormal conditions of objects (auto-manufacturing), feeling of objects (medical product), robotics, safety diagnosis of structure, etc.etc.

Through smart work using by smart technologies, many organizations wish to change traditional working styles. Lots of organizations, however, wish to do work with smartness through adoption of smart work technologies, those are not sure whether smart work will be successful or not till now. Viewpoints of members concerning efficiency and effectiveness from smart work who operate the organizations may be different. Therefore, hopefully, this research tried to investigate whether differences among members of organizations by empirical and exploratory approach. Totally, 118 questionnaires had been collected and performed test of mean difference between groups. As a result, some items such as working place, working methods, flexible time and tension of smartwork showed significant differences among groups and non-leader and leader groups. And, furthermore, from this research I believe that we can have a few insights for successful smart working environment in organizations. For successful smart work, organizations have to try to overcome or minimize differences among members of organization.

Since smart phones are changing the media for communication and its related mobile market, it is imperative to attract more application developers for success in application store business in order to attract more app users. By using aspects of the commitment marketing theory and the relationship marketing theory, this research study identified factors that influence on the relational commitment of application developers to the market. Survey of application developers from Korean mobile application developers' community was conducted to test the hypothesized model. The empirical results showed from an economic behavioral perspective market demand for applications and perceived usefulness of development tool led to relational commitment of developers mediated by perceived satisfaction while attractiveness of alternatives had no significant effect. In addition, fairness of review process and interactivity, based on the relationship marketing theory perspective, showed significant effect on the relational commitment of developers mediated by trust for application market.

Ubiquitous computing is an emerging technic for various areas such as public, private (individual), military, industrial, medical sectors. The applications of ubiquitous computing are expected to be prevailed from home to office. Unfortunately, it is not effective to apply existing system/software development methodologies into this emerging ubiquitous computing applications. In this paper, MBASE (Model-Based system Architecting and Software Engineering) is applied as a development method of ubiquitous computing applications. The advantage of MBASE is to identify mismatches of product, process, property, and success models and resolve them in developing the ubiquitous computing applications. A SmartView, a ubiquitous computing application, is presented as a case study o f MBASE.

In this paper, we tried to find the engineering feasibility of the component functions of the seven selected application technologies which are going to be installed on the next generation high speed train as the IT and smart sensor application technologies. The component functions of the seven applications, including the "Emergency or reminder notification", were identified and analyzed. In order to justify the feasibility of applications development, effect analysis and sufficiency analysis were performed. In effect analysis, how each function has an effect on safety, convenience, and efficiency of the passengers and attendants was evaluated. In sufficiency analysis, the importance and implementability of each function as a component was evaluated. The feasibility analysis was focused on the technical aspects of the functions. The following work will be the settlement of the final applications that are going to be designed and implemented. This will be done by studying the strategic feasibility in relation to the service or business of the high speed train.

The Internet of Things market, a technology that connects the Internet to various things, is growing day by day. Besides, various smart home services using IoT and AI (Artificial Intelligence) are being launched in homes. Related to this, existing smart home-related studies focus primarily on ICT technology, not on what service improvements should be made in customer positions. In this study, we will use smart home application customer review data to classify functional and design elements of smart home usability value and examine the ways customers think of service improvement. For this, LG Electronics and Samsung Electronics" Smart Home application, the main provider of Smart Home in Korea, customer reviews were crawled to conduct a comparative analysis between them. In this study, the review of IoT home-applications was analyzed to find service improvement insights from customer perspective, and related analysis of text mining, social network analysis and Doc2vec was used to efficiently analyze data equivalent to about 16,000 user reviews. Through this research, we hope that related companies effectively seek ways to improve smart home services that reflect customer needs and are expected to help them establish competitive strategies by identifying weaknesses and strengths among competitors.

LCD의 대중화로 인해 TV는 혁신적으로 얇고 넓어졌으며, 이를 통해 많은 가정에서 손쉽게 대형 TV를 보유할 수 있게 되었다. 이후 TV 기술은 대형화, 고화질 등에 초점을 맞추어 왔지만, 최근의 TV는 이러한 기류에서 한 발짝 벗어나 인터넷 접속이 가능하고 범용OS를 탑재하여 다양한 기능을 탑재할 수 있는 스마트 TV로 발전하고 있다. 하지만 스마트 TV에 어울리는 조작체계는 아직 부족한 실정이다. 특히 스마트 TV 게임 콘텐츠에 있어서 충분한 상호작용성을 제공하는 방법이 체계화 되어있지 않다. 이에 본 논문에서는 스마트 TV 게임의 상호작용성을 높이기 위한 스마트 TV와 스마트 디바이스의 연동 방법론을 제시하고자 한다.

스마트TV는 2000년대 초 등장한 스마트폰과 더불어 새로운 산업시장을 형성하고 있다. 스마트폰의 등장과 IT기술의 발전으로 사용자들은 더욱 만족도가 높은 애플리케이션을 추구한다. 스마트폰은 다양한 애플리케이션으로 사용자들의 요구를 충족하고 있지만 스마트TV는 사용자의 요구를 반영한 애플리케이션의 부재로 발전의 저하를 초래하고 있다. 스마트TV가 대중화 되고, 사용자의 요구를 충족시키기 위해서는 고사양의 애플리케이션이 아닌 스마트TV가 스마트하다고 느낄 수 있는 접근이 필요하다. 그러므로 본 논문에서는 최신 IT기술을 이용하여 스마트TV 애플리케이션을 제안한다. 이는 스마트TV, 스마트폰, 헬스자전거를 하나의 시스템으로 연동하여 사용자에게 실제 거리를 주행하는 것과 같은 느낌을 제공한다. 이를 위하여 Web OS, HTML5 웹 소켓, 안드로이드 기술을 이용한다.

최근 스마트폰 어플리케이션 시장은 급속히 성장하고 있고, 사용자들은 향상된 스마트폰의 기능을 이용하여 다양하고도 풍부한 사용 경험을 원하고 있지만 스마트폰 어플리케이션의 개발은 쉬운 작업이 아니다. 각종 스마트폰 센서들을 컨트롤하기 위해서는 각각의 스마트폰 OS에 맞는 네이티브 프로그래밍 언어를 전문적으로 사용할 수 있어야 하며, 더구나 개발 프로세스는 각 스마트폰 OS에 따라 별도의 작업으로 이루어져야만 한다. 웹 공통 API를 이용하는 웹기반의 스마트폰 응용 (일명, '웹앱') 개발 방법은 이와 같은 문제를 해결할 수 있게 해준다. 그것은 웹 언어인 HTML로 인터페이스를 구현하고 자바스크립트로 웹 공통 API를 호출하여 각 스마트폰의 디바이스 API에 접근할 수 있도록 하는 것이다. 본 논문에서는 웹 공통 API를 이용한 편리하면서도 OS 독립적인 스마트폰 웹앱(WebApp) 개발 방법을 사용하여 스마트폰 전자책 응용을 구현한 경험을 소개한다.
