실시간으로 뉴스 기사를 제공하는 온라인 뉴스 시스템이 널리 사용되면서, 사람들은 매 순간 속보와 새로운 뉴스 등 대량의 뉴스 기사에 노출되어 있다. 하지만 방대한 뉴스들로부터 사용자가 원하는 뉴스를 찾는 것은 매우 어려운 일이다. 따라서 개인 관심사에 따라 뉴스를 추천해주는 개인 맞춤형 뉴스 추천 시스템의 필요성이 증가되고 있다. 본 논문에서는 사용자의 관심사를 분석하여, 사용자의 관심사에 따라 관련된 뉴스를 자동으로 추천해주는 뉴스 추천 시스템을 설계 및 개발한다. 제안 시스템은 각 사용자가 북마크한 뉴스 기사와 읽은 뉴스 기사를 클러스터링하여 사용자별 프로파일을 생성한다. 또한 전체 뉴스 기사들을 클러스터링하여 주제 별로 분류한다. 사용자에게 뉴스를 추천하기 위해, 제안 시스템은 해당 사용자 프로파일에 포함된 각 클러스터에 대해 전체 뉴스 기사에 대한 클러스터들 중 가장 가까운 클러스터를 찾아 해당 클러스터 내의 뉴스 기사들을 거리 순으로 추천한다. 실제 구현된 시스템을 통해, 제안한 뉴스 추천 시스템이 각 개인에게 뉴스를 효과적으로 추천함을 보인다.

In this paper, we have designed and implemented a personalized health training system which provides health training methods using 3D animation based on the data from a professional trainer, after a trainee inputs individual physical characteristics. Many trainers at fitness centers provide only sketchy training method and usage of fitness machines not appropriate training method for trainee's physical characteristics. Individual characteristics. Individual characteristics prepared tabular input which consists of exercise goals, exercise areas, whether or not the normal movement, and RM. The system provides the training methods, the effects of exercise, and the health training motions through searching the database more accurately.

In this study, we develop a RSS-based educational information system for providing users, such as teachers, students, and parents of students with an adapted information. In order to collect an educational information from diverse web pages we design a web-based RSS reader. The RSS reader reads RSS files from the web sites or blogs which provide RSS feeds and then creates XML documents. The created XML documents are classified and registered into the system. Whenever the registered web-pages are updated, the system can automatically collect the updated information and provide the user with it. Therefore the user can be provided a real-time adapted educational information without searching web-sites from the system.

Individual's body is different depending on the body type or growing environment. In particular, recent changes in the way the movement toward a healthy 100-year-old range. But the purpose of the exercise, each person, gender, age, physical condition and how this movement should be applied according to analysis, to be studied. In this paper, we share information through this exercide method by online, and provide personalized workout, and an algorithm for research analysis. This study will be the cornerstone of research by combining biotechnology and IT to contribute to the health of the people 100 years old.

In smart healthcare service, the accurate and prompt emergency detection and notification are very critical to patients' lives. Since these detection and notification of emergency situation are usually performed by the medical staffs, it is difficult to simultaneously support many patients in real-time. This article presents a methodology for emergency bio-data transmission for smart healthcare using personalized emergency policy. It consists of three steps: In step 1, the bio-data is collected by wireless body area network. In step 2, the decision on emergency is made using personalized emergency policy. In step 3, the emergency message including the health condition information is converted between IEEE 11073 PHD message and HL7 CDA. By doing this, the emergency status of the individual bio-data collected from wireless body area network is detected automatically using personalized emergency policy. When the emergency is detected, the quick emergency rescue service can be provided to the patient by delivering to the emergency notification and the emergency bio-data. We have verified the service and functions of the proposed system architecture by realizing it.

The 'level of difficulty' is one of the major factors for learners when selecting learning contents. However, the criteria for the difficulty level is mostly defined by the contents providers. This approach does not support the personalized education which should consider the abilities and environments of various learners. In this research, the knowledge of the learners and contents were formalized and generalized to resolve the issue, and object models, including a metric for personalized difficulty level, were designed in order to be applied for experiments. And then, based on 100 contents for music education and 20 learners, we performed simulations with an implemented tool to validate our approach. The experimental results showed that our method can calculate the personalized difficulty levels considering the similarities between the knowledges from the learning state and the contents. Our approach can be effectively applied to the on-line learning management system which contains easy access to the learning state and contents data.

Currently Korean government is rushing the new electronic government system introduced as 'platform e-government' with big data and cloud computing technologies and systems, ultimately intending to provide the public institution services customized from the integrated counter or window for the heterogeneous resident services. In this regard, this study suggested how to design the new metadata information system in which mutual integration of information systems can take place, where heterogeneous services can be shared efficiently at the application and data unit, as a separate application that can provide a single one- stop service for residents' petition at the integrated level in the back-office based on the public data in possession of each of government ministries and related organizations. If this proposed system is implemented, the achievement of customized public service can be advanced one step forward in processing the petitions of the residents by organically connected link between 'Demand Chain' and 'Supply Chain' in the integrated window. In other words, it could be made possible through the unification of both the 'Supply Chain' performed in the office space of the officials at the back-office level and the 'Demand Chain' performed in the living space of the residents at the front-office level.

In ubiquitous environments, invisible devices and software are connected to one another to provide convenient services to users. In this environments, users want to get a variety of customized services by using only an individual mobile device which has limitations such as tiny display screens, limited input, and less powerful processors. Therefore, The device sharing for solving these limitation problems and its efficient processing is one of the new research topics. This paper proposes a device recommender system which searches and recommends devices for composing user requested services. The device recommender system infers devices based on environmental context of a user. However, customized devices for each user are different because of a variety of user preference even if users want to get the same service in the same space, Therefore the paper considers the user preference for device recommendation. Our device recommender system is implemented and tested on the real mobile object developed for device sharing in ubiquitous environments. Therefore we can expect that the system will be adaptable in real device sharing environments.

This paper discusses the possibility of enhancing the efficiency in Second Language Learning with the help of an educational information and content search system that utilizes a Cloud system based Big Data. The proposed system plays a role in tracing the exact information that user request considering the interest, level, and aptitude of each individual. Also, the system screen outs unnecessary learning materials if they do not correspond to the user level which in result is one of the key factor in the proposed system. Since it requires multiple steps of verification in providing the extracted results finding out a way to reduce the steps to shorten the time of process.

Interest in food recipe retrieval systems has been increasing recently. Most computer-based recipe retrieval systems are searched by cooking name or ingredient name. Since each recipe provides information in different weighing units, recalculations to the desired amount are necessary and inconvenient. This paper introduces a computer system that addresses these inconveniences. The system is a chatbot system, based on web-based recipe recommendations, for users familiar with the use of messenger conversation systems. After selecting the most popular recipes by their names, and pre-processing to extract only information required for the recipes, the system recommends recipes based on the 100,000 data. Recipes are then searched by the names of food ingredients (included and excluded). Recalculations are performed based on the number of servings entered by the user. A satisfaction rate for the systems' recommendations was 90.5%.
