Recently, many automotive companies tend to apply an air quality system (AQS), which prevents polluted air such as smoke or dust by controlling air intake actuator of vehicle, to satisfy the consumer's need for agreeable in-vehicle environment. However, performance of the traditional AQS is not satisfactory because a polluted air may enter into the inside of vehicle through the breaks of windows. Especially, the commercial vehicles such as bus or truck need to be prevented polluted air from the breaks of vehicle. Hence, as an alternative to the traditional AQS, this paper presents the architecture of smart AQS for commercial vehicle and implementation of the smart AQS. Also, the performance of the suggested system is evaluated through an experimental testbed.

The C-ITS (Cooperative-intelligent Transport System) is a driver assistance system that prevents car accidents and enhances traffic conditions, via sharing traffic information between vehicles and roadway infrastructures. A CLAS (changing lane assistance system) for unprotected left-turn, is a C-ITS that assists a driver with safely changing lanes. This system addresses a driver's critical gap, that enables the system to express a driver's uncertainty. A driver's critical gap is a time that can be used in a threshold, to change a lane or not. Unfortunately, a driver's critical gap is difficult to use in a CLAS directly. This paper addresses a driver's critical gap, and how it can be applied in a CLAS for an unprotected left-turn.

Products companies, which manufactures finished goods with modular parts, will expect that the proper parts should be delivered to assembly line not only just in time (JIT) but also just in sequence (JIS) and also expect that faulty goods will not be produced due to the delivery of wrong parts. In order to satisfy the above requirements, recently Smart Pallet based Parts Delivery system (SPPD) was proposed. SPPD system can overcome the drawback of bar code based part delivery system in which much time for checking proper and in sequence parts is wasted due to labors' working in hand as well as the drawback of RFID based part delivery system in which recognition distance of RFID is very limited. In the paper, a PDA system is proposed and further implemented to maximize the efficiency of SPPD's operation as well as to manage the limited power of smart pallets efficiently.

One of the major requisites for the success of the smart-TV is to create a circumstance where smart-TV app's are produced and purchased on a large scale. However, the smart TV app's may succeed only under the condition that the user interface of the smart TV is greatly evolved from the typical TV remote controller. Several equipments have been devised to tackle the problem of the poor user interface of the smart-TV; however, they are not satisfactory in the aspects that they usually increase the costs of TV-set and they do not help practically the app developers. The equipments are pre formed so that it is hard for the app developers to design their own user interface using them. In the paper, sMartUX, a method for developing the smart-TV app is introduced. sMartUX provides a new paradigm and development environment for designing, implementing, and operating the user interface of the smart TV app using a smart-phone. With sMartUX, app developers can design their own user interface using the various facilities of a smart-phone, and they need not to care the details of various smart-phones and how to launch their user interface onto a smart-phone.

Development of smart devices and the network of the company change the way of working. 'Smart work' is a type of work method expected to handle business regardless of the time and space. Therefore, 'Smart Work' is being introduced and gradually expanded in variety of companies. However, despite this popularity its effect is under question. This article reports on the effect of 'Smart Work' through literature review and analyzed the relationship among the worker's job satisfaction, smart work continued usage. The results of this study are expected to help companies to establish strategies connected with 'Smart Work.'

Real Estate Auction Information System purposes on providing high quality information of auction customized to consumer's situation and preference. Especially, ever-changing real time information such as the number of hits and advanced analysis for expecting the winning bid are requiring of mobile information system based on context awareness. Therefore, this paper studies on Real Estate Auction Information System based on context awareness under a smart phone environment providing auction information such as consumer's current position, the number of hits to a specific real estate, and the number of bidder to anticipate the winning bid.

사람들은 자신의 일정을 관리할 필요가 있으며, 이를 자동으로 관리할 수 있도록 Smart Adapted Service (SAS)를 제안한다. 사람들은 자신의 일정을 웹서버에 메모하며, 제안하는 시스템에서 일정을 관리한다. SAS는 저장된 일정을 미리 알려주며, 일정을 수행하는데 필요한 정보를 인터넷에서 검색하여 능동적으로 제공해준다. 이는 웹서비스 엔진을 통해 가능하다. 또한 구입하고자 하는 물건이나 먹고 싶은 음식을 기록하면 주변상점의 정보를 검색하여 사용자에게 맞춤 정보를 제공해준다. 이는 유비쿼터스 환경이라는 가정 하에 실시간 자동 AP 로밍 시스템을 이용한다. 또한 SAS는 사용자가 선호하는 데이터를 기억하고 추천해주기도 한다. 개개인의 감정 및 피로도를 기반으로 건강을 체크해주기도 한다. 이러한 기능을 하는 시스템을 구현하고 가능함을 확인했다.

Recent advances in healthcare-adapted devices, the increase in chronic diseases and the increasing social needs due to aging, trigger the development of smart healthcare systems and present a new medical paradigm. As a result, moves are being made to accommodate the changing healthcare concept of modern residential areas. In particular, the bathrooms in residential areas are becoming diverse as medical spaces with various types of bathroom culture. Therefore, by actively utilizing the digital medical procedure 3, the smart health care system was applied, I thought about future bathroom products (like smart shower and smart scales) and searched for the technology necessary for each person's needs. By planning a product suitable for a changing bathroom, it will be useful for the development of smart healthcare technology through future national and policy improvements in preparation for the age of the fourth industrial revolution.

Autobike is insufficient of car navigation informations and high of accident dangerousness comparing to car. So if a system providing autobike driver's driving information and e-call function is developed using smart helmet consisting of collision perception sensor, rear camera, bluetooth communication module, MCU and HUD, It is very useful and can decrease of person's damage and handle expeditious traffic accident during autobike accident. In this paper, when this, "Providing system of autobike driver's information and e-call function", software is developed, a proper analysis and design method for practical affairs try to be presented due to showing software development analysis method, architecture of hardware block-diagram, flowchart and UI design.
