  • The purpose of this study was to identify the relationships among smart phone use motivations, addiction, and self-control in nursing students. Data were collected from June 10-18, 2013. Smart phone use motivations and addiction showed significant differences according to sex, record. Smart phone high-risk users got high-score in use motivations especially entertainment/leisure, service, and functionality, and low-score in self-control. The factors affecting smart phone addiction were record, tolerance, abstinence, difficulty of daily living, and aim for virtual world which accounted for 88.2%. Also factors affecting addiction were entertainment/leisure, flaunt/trend which accounted for 12.9%. In conclusion, smart phone use motivations was correlated positively with addiction, while addiction was correlated negatively with self-control. Therefore more positive and desirable ways of smart phone use, and plans for improvement of self-control should be studied.

  • Recently, request of IPTV was increase. It is a multi-screen service by used TV, PC, and smart-phones. Especially, IPTV and smart-phone linked multi-screen service are very growth by user's recommends. Now, IPTV have a security service partial and multi-screen service. But smart-phone and multi-screen service don't have security service. And authentication service for smart-phone and IPTV linked multi-screen service is don't.. Therefore, We propose that user authentication system for multi-screen service with IPTV and multi-device linked authentcation services. Our proposed system base on Kerberos, so proposal is easy and fast about user authentication. This have simple procedures and more secure services against of PKI. So, our system can support secure multi-screen services against various security threats in multi-screen environments.

  • In this paper, a service system which shows linked video clips from the static images extracted from newspapers, magazines, photo albums and etc in an augmented reality. First, the system uses SURF algorithm to extract features from the original photos printed in the media and stores them with the linked video clips. Next, when a photo is taken by using a camera from mobile devices such as smart phones, the system extracts features in real time, search a linked video clip matching the original image, and shows it on the smart phone in an augmented reality. The proposed system is applied to Android smart phone devices and the test results verify that the proposed system operates not only on normal photos but also on partially damaged photos.

  • This research is based on real-time service model that uses lock screen of smart devices which is mostly exposed to device users. The potential for lock screen space is immense due to their exposing time for user. The effect can be maximized by offering useful information contents on lock screen. This service model offers real-time keyword with abridged sentence. They match real-time keyword with news by using text matching algorithm and extracts kernel sentence from news to provide short sentence to user. News from the lock screen to match real-time query sentence, and then only to the original core of the ability to move a user evaluation was conducted after adding. The report provided a key statement users feel the lack of original Not if you go to an average of 5.71%. Most algorithms allow only real-time zoom key sentence extracted keywords can accurately determine the reason for that was confirmed.

  • The Object of smart healthcare service is focused on preventive healthcare and wellness; It also aims for the user oriented active service. Recently, Smart healthcare using smart-phone can support various services like basal physical fitness, caloric intake, checking heartbeat and so on. However, it has not yet commercially viable service model because of incomplete personal health devices standardization. We designed and implemented Android smart healthcare Manager to support ISO/IEEE 11073 by Bluetooth HDP using oximetry System.

  • As the techniques of electronic and information are advancing, the computing power of a smart phone is becoming more powerful and the storage capacity of a smart phone is becoming larger. As the result, various new useful services are becoming available on smart phones. The context-aware service and mobile augmented reality have recently been the most popular research topics. For those newly developed services, identifying the object in the picture taken by the camera on the phone performs an extremely important role. So, many researches of identifying pictures have been published and most of them are based on the time consuming image recognition techniques. On the contrary, this paper introduces a very fast and effective method of identifying the objects on the photo making use of the sensor data obtained from the smart phone and electronic maps. Our method estimates the line of sight of the camera with the location and orientation information provided by the smart phone. Then it finds any element of the map which intersects the line of sight. By investigating those intersecting elements, our method identifies the objects on the photo.

  • With Internet of Things (IoT) technology, home environment becomes smarter than ever. Not only smart devices such as smart phone or smart TV, but also various IoT devices including sensor, smart thermostat, and smart scale has now become very common on the market. These devices have connectivity to the Internet, so that user can read data from the device or control the device using Internet technology. However, due to diversity of smart home requirements, device collaboration in smart home remains a challenging task still. Usually smart home is built with various technologies to fulfill its own purpose, and these purposes cover very wide area from controlling low-power sensor devices to controlling high-performance devices like smart TV and smart phone. This variety of smart home requirements makes smart home very complicated due to mixed network architecture, protocol and technology. In this paper, a framework to enable managing and collaborating heterogeneous IoT devices in smart home environment is proposed. Several programming models are defined in the proposed framework to make application development for heterogeneous devices more intuitive. The proposed framework has been implemented as a web service, and a case study with real-world smart home IoT devices is presented.

  • Currently, every person possesses a smart phone due to the development of the IT industry. However, crosswalk pedestrian accidents have been sharply increasing due to smart phone use. If a traffic light can recognize smart phones when a smart-phone user approaches and arrives at a given sign, many accidents could be reduced by using beacon signals. Before the era of smart phones, the accident rate involving cell phone use was relatively low. Nevertheless, when considering the development of IT equipment that produces a threat to human life, government cannot regulate smart phone use outside. The purpose of this paper is to indirectly warn a smart phone user in order to reduce the accident rates.

  • Recently, value added location based service and convergence monitoring and control system is growing. The cases include increasing usage of smart-phone for taking picture, wireless network, GPS and digital map. Especially, Smart-phone is appropriate for using image information and location information. However it is possible to be exploited for forgery and manipulation. So we experimented on transferring modified data on the smart-phone as image and location information in EXIF and researched the technology for data verification. In addition, we have designed security monitoring and control prototype considering axis-address matching analysis used geocoding, watermarking verification, encryption.
