This paper proposes a new method for tracking image contents, which are re-distributed on the Internet using a web-robot and fingerprinting scheme. The fingerprinting is an extended technique of watermarking and embeds identity of the customer into the content as a fingerprint in a way that is very difficult to erase. The fingerprint in the content can be used widely in the field of the copyright protection technique because it identifies the content itself and includes the information about the original customer. In this paper we discuss an active image tracking system using a web-robot and fingerprinting scheme. In the proposed system the information of the original customer is embedded as a fingerprint into the image content before distribution and also stored into DB. The distributed contents are collected by the web-robot and fingerprinting information is extracted from the contents. Finally the identifying of contents is done by comparing the extracted fingerprint with the selling history of the content.

The purpose of this study is to understand the content characteristics in YouTube videos of the National Archives of Korea. For this purpose, keywords, video data, and viewer responses were collected for 324 videos posted by the National Archives of Korea for five years since April, 2017. Social network analysis, topic modeling, and content analysis were performed. Based on this, the main keywords leading the YouTube videos of the National Archives of Korea, 7 major topics and 20 sub-topics were identified. The characteristics of the YouTube videos and keywords network were studies. In addition, video characteristics were analyzed as external characteristics, video editing and delivery methods, and content characters. The study found that the YouTube channel of the National Archives of Korea has been posting the videos related to various topics such as places, history, and events as well as the basic functions of the archives to induce viewers' interest in the archives. The study also identified the areas that needed to be improved such as low response from viewers, lack of content that could interest viewers, and lack of channel operation to interact or communicate with viewers. Finally, the study was concluded with a proposal to spread the videos of the National Archives of Korea to more users.

The study designs and implements a KORMARC/EAD integrated system for the Myongji Digital Library Collections. The purpose of this paper is to design the metadata to Myongji Korean History Collections to provide digital information of high quality to clients, and to develop and implement a model for managing digital library collections. In order to test the model and the quality of the derived metadata, we built a metadata management system, which is connected to the existing KORMARC system. The system consists of two modules- a retrieval and an input module. While in the retrieve mode, one can retrieve KORMARC records of books and archival items, with links to modified EAD files for archival items or to image files for books, in the input mode, one can type two types of data such as a catalog data and an inventory data. Finally, we evaluated the proposed system via mail questionnaires, and propose three suggestions to make this system a much more comprehensive and effective system.

To enhance the efficiency of network, content-centric networking (CCN), one of future Internet architectures, allows network nodes to temporally cache transmitted contents and then to directly respond to request messages which are relevant to previously cached contents. Also, since CCN uses a hierarchical content-name, not a host identity like source/destination IP address, for request/response packet routing and CCN request message does not include requester's information for privacy protection, contents-providers/ network nodes can not identify practical requesters sending request messages. So to send back relevant contents, network nodes in CCN records both a request message and its incoming interfaces on Pending Interest Table (PIT). Then the devices refer PIT to return back a response message. If PIT is exhausted, the device can not normally handle request/response messages anymore. Hence, it is needed to detect/react attack to exhaust PIT. Hence, in this paper, we propose improved detection/reaction schemes against attacks to exhaust PIT. In practice, for fine-grained control, this proposal is applied to each incoming interface. Also, we propose the message framework to control attack traffic and evaluate the performance of our proposal.

We developed a Smartphone application based on PHR(Personal Health Records) provided by a tertiary hospital to provide users personalized diet, exercise contents. It uses Relevance ratio algorithm of diet and excercise being correlated with diseases listed on PHR to provide personalized contents to management of individual diseases and record the amounts of food taken and exercise along with calories consumed through exercise. Besides, developed U-Health Service also considering users' conditions and conveniences, as a service to use contents and record suitable for the individuals who share the information on restaurants locations, their menus, and nutrition based on users' location information.

The purpose of this study is to present a proposal to build an archive of Gwangju Student Independence activist Jang Jae-seong. The research method used for this purpose was, first, a literature study related to Jang Jae-seong. Second, the current status of records related to Jang Jae-seong, such as the National Archives of Korea and the Ministry of Patriots and Veterans Affairs, was investigated, and the types of records were presented for each collection. Third, an expert interview with Jang Jae-seong's family was conducted. As a result of the study, the Jang Jae-seong archive was designed with documentary and commentary content. In addition, a method of linking with the record-holding institution through mapping by content was suggested. Recorded content are structured so that users can receive detailed information linked to each collection through a search. Also, considering that an archive of Gwangju student independence activists has not been established so far, a plan was prepared and presented to build an archive of people involved in the incident together and provide data.

전자매뉴얼은 기존의 기술 문서를 전자 문서화 한 것으로 멀티미디어 콘텐츠의 활용도가 높은 분야 중 하나이다. 전자매뉴얼은 3D 콘텐츠를 포함할 가능성이 매우 높으며 이 때 직관적이고 정교한 3D 조작 인터페이스가 요구된다. 또한 그런 3D 인터페이스에서의 조작 정보 역시 적절하게 저장하고 재생하는 방법이 존재한다면 조작 정보의 재사용을 통한 복수의 사용자간의 정보 교환을 가능하게 할 수 있다. 본 논문에서는 사용자 중심의 직관적인 3D 사용자 인터페이스와 조작의 기록과 재생을 가능하게 하는 Process Annotation 기법이 적용된 전자매뉴얼의 3D 콘텐츠를 제안하고, 실제 프로토타입으로 구현하였다.

Compared to penetration of Electronic Medical Record(EMR) system, Healthcare Information Exchange(HIE) has been less active in South Korea. The aim of this study is to explore medical law newly legislated to introduce HIE through the nation. The important insights are that the medical institutions exchange the patient's healthcare information based on the consent of the patient, and it is expected to be set up and managed the medical record exchange support system by the government and a consignment organization. In addition, the certification program for standardization and interoperability on the EMR system would be conducted. Nevertheless, continued policy developments and researches for the promotion of HIE will be urgently needed such as the education for the vendors and developers, developments of the certification programs and the incentive payment programs and the public relations.

호랑이는 죽어서 가죽을 남기고 사람은 죽어서 이름을 남기고, 큰 맘 먹고 나섰던 여행은 일상으로 돌아올 때 '사진'을 남긴다. '기록은 기억을 지배한다'는 어느 유명한 디지털카메라 제조업체의 광고문구처럼, 여행 후 남은 한장의 사진은 추억의 일부가 된다. 여행과 사진은 참으로 잘 맞는 궁합이다. 여행에 사진이 없더라도, 사진을 찍으러 굳이 여행을 떠나지 않더라도 크게 상관은 없지만, 이들이 어우러지는 경우 훌륭한 작품이 되곤 한다. 사진을 찍는 사람에게는 잊을수 없는 추억이, 사진을 보는 사람에게는 동경의 대상이 되는 게 바로 사진이다. 이번 호에서는 사진이라는 콘텐츠가 '지도'라는 정보를 만나서 더 좋은 추억과 기록으로 남을 수 있는 방법을 소개하고자 한다.
