A study proposes possibility of new IoT measuring system blended with a smart device. The research serves the best cultivation information for domestic fruit's enhancement of competitive power and also develops a glucose measuring system by which people manage fructose with the mobile device. The mobile glucose tester is designed with a form of accessory which has high portability and utility because the product connects an existing analogy refractometer to the smart phone. You can check the glucose rates data by commodity, region, and season then save measurement results with server in real time for an exclusive application. It's possible to serve the glucose map, graph, and data list through the web service. This is very useful to do collect, analyze, and process the glucose data.

As computer network and wireless technology continue to grow rapidly, a wide range of remote application has been applied to medical field such as remote medical consulting and remote patient monitoring. This research aims to design RF telecommunication-based healthcare application to collect and manage patient's physiological data, and describe the overall procedure of experiment. MySQL database is designed to record patient's physiological data including temperature, blood pressure and heart rate and save information about medical behaviors such as doctor's prescription for patients. Therefore, users approved by healthcare application can query patient's data and collected data can be used to reorganize data for clinical test. As a result, temperature and humidity of patient's room which must be checked frequently can be processed automatically through ubiquitous sensor network. The information entered from mobile phones or web is saved in database, ensuring systematical management through computer. Moreover, patient's family members can easily access hospital data, improving their experience with medical service.

An effective integration of web-based learning environment and mobile device technology is considered as a new challenge to the developers. The screen size, however, of the mobile device is too small, and its performance is too inferior. Due to the foregoing limit of mobile technology, displaying bulk data on the mobile screen, such as a cyber lecture accompanied with real-time image transmission on the web, raises a lot of problems. Users have difficulty in recognizing learning contents exactly by means of a mobile device, and continuous transmission of video stream with bulky information to the mobile device arouses a lot of load for the mobile system. Thus, an application which is developed to be applied in PC is improper to be used for the mobile device as it is, a player which is fitting for the mobile device should be developed. Accordingly, this paper suggests mobile presentation using transcoding techniques of the field concerned. To display continuous video frames of learning image, such as a cyber lecture or remote lecture, by means of a mobile device, the performance difference between high-resolution digital image and mobile device should be surmounted. As the transcoding techniques to settle the performance difference causes damage of image quality, high-quality image may be guaranteed by application of trial and error between transcoding and selected learning resources.

As growing up of elderly population, the interesting on healthcare system in normal life using W is increasing. An integrated u-healthcare service architecture with IEEE 802.11 and IEEE 802.15.4 based sensor network and code divisi(m multiple access(CDMA) public mobile telecommunication networks was designed and developed. Sensor nodes with electrocardiogram(ECG), body core temperature sensors are attached on the patients' body. The healthcare parameters are transferred to web server via CDMA mobile network or through existed LAN network. The existed LAN network is suggested to be used for continuous monitoring of patient's health status in hospital while mobile networks can be used for general purpose at home or outdoor where infra networks unavailable. This system enable healthcare personal to be able to continuously access, review, monitor and transmit the patients information whereever they are, whenever they want. And immediately check their status by using cellular phone and obtain detail information by communication with medical information server through CDMA. By using this developed integrated u-healthcare service architecture, we can monitor patients' health status for 24 hours.

As the population ages socially and the diet of people becomes westernized, the incidence of chronic diseases is increasing due to irregular lifestyle. Chronic diseases can be prevented and improved with just regular lifestyle and diet. Most of the recently released diet management mobile applications are aimed at obesity management and diet, and applications that aim to prevent or improve chronic diseases are hard to find. In this paper, we develop a web service that identifies diabetes most frequently encountered among chronic diseases, and implements a chatbot service that helps diabetes management by using Chatscript.

앞으로의 멀티미디어 기기시장은 기존의 단순 복합 디지털 기기들이 아닌 사용자 감성 및 취향 제어가 가능한 인간 친화적 지능형 멀티미디어 기기가 주류를 이룰 것이다. 이미 IT 기능이 기존의 '정보의 소통'에서 '감성의 소통'으로 진화 중에 있으며, 미래시대에는 느낌까지 디지털 신호로 전달 가능한 기술이 발달 될 것이다. 이에 맞추어 사람의 감성, 주변 분위기, 섬세한 공간 정보를 전달하는 사실적인 오디오 개발 및 인프라가 구축되어 모든 멀티미디어 제품에 적용된다면, 사용자는 보다 현장감 있게 멀티미디어를 즐길 수 있을 것이다. 최근 스마트폰의 확산과 더불어 각종 다양한 음악서비스를 제고하는 웹/앱 형태의 어플리케이션이 증대되고 있는 바, 본 논문에서는 안드로이드 기반 스마트 모바일 기기에서 다양한 오디오 정보를 청취자에게 제공하고 이를 활용하여 청취자가 다양하게 오디오 재생 / 제어하여, 일방적으로 청취자가 오디오를 듣는 수준이 아니라 청취자 취향에 따라 다양하게 오디오를 감상 할 수 있는 서비스를 구현하였다.

스마트 폰의 등장과 모바일 인터넷을 제공함에 따라 휴대폰은 음성통신 수단이 아닌 웹을 통하여 서비스를 제공받는 도구 또는 각종 게임 및 응용 어플리케이션을 제공하는 놀이수단으로도 발전하였고, 이로인하여 사용량도 증가하였다. 사용량의 급증으로 인하여 모바일 광고에 대한 업계의 관심도 증가 하였지만, 한정적인 출력화면에 의하여 제한적일 수밖에 없다. 이를 보완하기 위해, 본 논문에서는 기업의 로고 광고의 효과를 극대화 할 수 있는 안드로이드 기반 로고를 인식하는 증강현실 시스템을 제안 하였고, 이를 구현 하여 실 제폰에 탑재한 후 다양한 성능 분석을 하였다. 실험결과, 그 가능성은 확인하였지만 현하드웨어 성능으로는 실시간으로 지원하기에는 역부족임을 알 수 있었다.
