In order to use an Internet service, it is a general procedure that user subscribes to the service and then registers her or his id(identifier). As Internet has been more widely used, however, user has more and more ids than ever before. In this environments, whenever user uses an Internet service, she or he must authenticate to the service provider, which makes her or him inconvenient. As user's data is scattered and unmanaged on various web sites, user privacy has been revealed more often. This paper specifies e-IDMS which ETRI has been developing to solve such problems. e-IDMS is an Internet ID(IDentity) management system based on ID Federation Mechanism e-IDMS provides ID Federation-based facilities such as composite authentication, Internet SSG, ID information management, privacy protection and interactive query. e-IDMS is used in establishing integrated ill management system for public institutions.

Touch-enabled technology is increasingly being accepted as a main communication interface between human and computers. However, conventional touchscreen technologies, such as resistive overlay, capacitive overlay, and SAW(Surface Acoustic Wave), are not cost-effective for large screens. As an alternative to the conventional methods, we introduce a newly emerging method, an optical imaging touchscreen which is much simpler and more cost-effective. Despite its attractive benefits, optical imaging touchscreen has to overcome some problems, such as heavy computational complexity, intermittent ghost points, and over-sensitivity, to be commercially used. Therefore, we designed a hardware controller for signal processing and multi-coordinate computation, and proposed Infrared-blocked DA(Dark Area) manipulation as a solution. While the entire optical touch control took 34ms with a 32-bit microprocessor, the designed hardware controller can manage 2 valid coordinates at 200fps and also reduce energy consumption of infrared diodes from 1.8Wh to 0.0072Wh.

As interactive multimedia have come into wide use, user interfaces such as remote controllers or classical computer mice have several limitations that cause inconvenience. We propose a vision-based pointing device to resolve this problem. We analyzed the moving image from the camera which is embedded in the pointing device and estimate the movement of the device. The pose of the cursor can be determined from this result. To process in the real time, we used the low resolution of $288{\times}208$ pixel camera and comer points of the screen were tracked using local optical flow method. The distance from screen and device was calculated from the size of screen in the image. The proposed device has simple configurations, low cost, easy use, and intuitive handhold operation like traditional mice. Moreover it shows reliable performance even in the dark condition.

The purpose of this study is to suggest the value and type of online and offline linked advertisement, which is a new advertisement type that emerged with the advent of the 4th industrial revolution. In this study, based on literature research, we understood the marketing method that evolves from "4P (product, price, place, promotion)" to "4C (co-creation, community, conversation, currency)" and extracted derive 4C elements. Based on this, we analyzed what elements of 4C showed online and offline connectivity through the investigation of on and offline linked advertisements. Through the analysis results, online and offline linked advertisements were classified into 4 types and 14 detailed types according to how they were connected to the number of 4C elements. In this paper, as a final result, we verified that 4C elements of marketing that appeared in the era of the 4th Industrial Revolution are represented in advertisements and suggested the typology of advertisements accordingly. This study is expected to contribute to providing new insights to advertisers and researchers who produce and study online and offline advertisements.

The purpose of this study was to analyze the differences of preschoolers' utterance features by their gender and play situation type. For this purpose, a total of 40 5-year-old children participated in this study. Dyad were participated in each play session during 10 minutes. The play session was videotaped and the videotaped data were transcribed by CBS(2014). The collected data were analyzed by using a independent t-test and paired t-test. The main results are as follows. First, girls' MLU-e, MLU-w, MLU-m were longer than that of boys in a familiar play situation. Second, preschoolers' MLU-w was longer in an unfamiliar play situation than in familiar ones and preschoolers' type-token ratio were higher in an unfamiliar play situation than in familiar ones. Implications for the importance of preschoolers' spontaneous speech are discussed.

The purpose of this study is to examine the relationships between fathers and children with Internet addiction. To achieve the goal, researchers chose face to face interview methods with 12 children who had been considered'at risk'with Internet addiction. More specifically, examiners conducted individual in-depth interviews with 12 children associated with Internet addiction for 30~40 minutes during four sessions through structured questions and non-structured questions. After collecting data, examiners conducted a categorical analysis based on collected data. Finally, the research results, discovered in this research, were as follows: First, the Internet set up the inter-generational barrier in the relationship between father and child, second, children took an interest in the Internet instead of their busy father, Third, the Internet played the role of a place to escape from the awkwardness with their father, fifth, fathers were not able to control the Internet use of their children. Based on the research results, this study suggests a desirable behavior pattern for fathers which can be conducive to children with Internet addiction and their fathers along with a follow-up study.

There has been some research into a speech system for communications between those who are hearing impaired and those who hear normally, but the system has been pursued in inefficient teaching ways in which existing teachers teach each individual due to social indifference and a lack of marketability. In order to overcome such a weakness, there appeared to be a need to develop contents utilizing 3D animation and digital technology. For the investigation of a standard face and a standard spherical shape for the preparation of a character, the study collected sufficient data concerning students in the third-sixth grades in elementary schools in Seoul and Gyeonggi, Korea, and drew up standards for a face and a spherical shape of such students. This data is not merely the basic data of content development for the hearing impaired, but it can also offer a standard measurement and a standard type realistically applicable to them. As a system for understanding conversations by applying 3D character animation and educating self-expression, the character speech animation system supports effective learning for language education for hearing impaired children who need language education within their families and in special education institutions with the combination of 3D technology and motion capture.
