휴대전화는 다양한 기술들이 융합되고 유비쿼터스 환경과 결합되면서 진화하고 있다. 이런 모바일 환경으로 인해 사용자의 상황을 인식하는 상황인식 기반 서비스들의 수요가 증가하고 있으며 사용자들은 그 상황을 실시간으로 공유하고 보기를 원한다. 따라서 본 연구에서는 모바일 사용자의 주변 상황을 인지하고 그 상황 정보를 공유할 수 있는 컨텍스트폰 플랫폼을 제안한다. 제안하는 플랫폼은 안드로이드 플랫폼을 기반으로 하여 사용자의 주변 상황을 실시간으로 수집하며 사용자간 자동 상황 공유 메커니즘을 지원한다. 또한 사용자 연락처의 상황 수집과 컨텍스트폰 플랫폼간 논리적인 연결을 위해 컨텍스트 서버를 구축하였으며 서버는 사용자간 동시다발적으로 발생하는 상황정보를 저장하고 사용자간 상황 정보를 전달해 준다. 또한 플랫폼이 수집하는 상황정보를 시각적으로 표현하기 위해서 컨텍스트 뷰어 어플리케이션을 구현하였으며 모바일 스크린에 시각화하였다.

다양한 매체를 통해 텍스트 데이터가 빠르게 생성되면서 요약된 텍스트에 대한 수요가 증가하고 있다. 시퀀스-투-시퀀스 모델의 등장과 attention 기법의 출현은 추상적 요약의 난도를 낮추고 성능을 상승시켰다. 그러나 그동안 진행되어 온 attention 기반의 시퀀스-투-시퀀스 모델을 통한 요약 관련 연구들은 요약 시 텍스트의 카테고리 정보를 이용하지 않았다. 텍스트의 카테고리 정보는 Class Activation Map(CAM)을 통해 얻을 수 있는데, 텍스트를 요약할 때 핵심이 되는 단어와 CAM에서 높은 수치를 보이는 단어가 상당수 일치한다는 사실은 요약문 생성이 텍스트의 카테고리에 의존적일 필요가 있음을 증명한다. 본 논문에서는 요약문 생성 시 집중 정도에 대한 정보를 CAM을 통해 전달하여 attention matrix를 보강할 수 있는 모델을 제안하였다. 해당 모델을 사용하여 요약문을 생성하고 대표적인 요약 성능 지표인 ROUGE로 측정한 결과, attention 기반의 시퀀스-투-시퀀스 모델이 질이 떨어지는 요약문을 생성할 때 attention의 성능을 보강하여 요약문의 질을 높일 수 있음을 알 수 있었다.

간병 서비스를 제공하는 데에 있어 가장 중요한 것은 간병인의 스트레스 관리 및 체력 관리이다. 그러나 요양 시설의 수요 증가량에 비해 간병인의 공급량은 줄어들고 있으며 고령화로 인해 노인이 노인을 간병하는 노노간병 사례가 증가하고 있다. 1인당 부양하는 환자 수의 증가와 간병인의 연령이 평균적으로 높아지면서 간병 스트레스 및 간병 살인 문제가 빈번하게 발생하고 있다. 본 논문에서는 환자의 EEG를 실시간으로 분석해 환자에게 필요한 것을 전달해주는 서빙로봇 간병서비스 개발 내용에 대해 기술하고 있다. 이 시스템을 통해 장시간 노동에 따른 간병인의 간병 스트레스와 간병 부담을 덜어줄 수 있을 것으로 기대한다.

Recently, the form of education has changed from one-way to two-way and mutual exchange rather than the existing one-way order form, and accordingly, it is necessary to consider creating a suitable learning environment for each type of education. The basic form of education consists of the delivery of knowledge, that is, the delivery of knowledge by teachers to education consumers through voice delivery, so the sound environment is considered an essential factor in creating a pleasant learning environment. The indoor sound environment is very closely related to the mental stress of the inmate, so the quality level of education will also change greatly depending on whether or not the appropriate sound environment is created. However, the importance of the sound environment in educational facilities such as classrooms has not been highlighted due to the lack of research and related laws on the sound environment. Therefore, in this study, auditory tests were conducted using the auralization based on the physical acoustic performance data presented in the preceding study. Through this, we wanted to verify the validity of this research by analyzing the subjective acoustic performance satisfaction of the occupants due to the improvement of the physical acoustic performance. Based on these research results, it is estimated that the improvement of the sound environment of educational facilities through remodeling in the future will be possible to verify whether the sound environment suitable for educational facilities is created only after the analysis stage on the improvement of subjective sound performance as well as physical sound performance.

The cyber university, which authoring systems for digital contents using multimedia technologies ate used for its courses, is highlighted to be a promising alternative for the current off-line education system. As the demand for the authoring system is constantly increasing, many systems, which emphasize the developers' convenience only, are currently used. Since the generated digital contents using these systems are failed to draw the learners' active interaction with contents, the new authoring system is expected to be existed. This paper presents, develops, and implements the new contents authoring system by using programing languages and/or software tools based on the storyboard. The presented, developed, and implemented system mimics the face-to-face education in off-line system, induces the users' active interaction with contents, and the effective evaluation system to the users.

For recent years, data broadcast technology has been recognized as a very effective data delivery mechanism in mobile computing environment with a large number of cli;ents. Especially, a hybrid broadcast algorithm in real-time environment, which integrates one-way broadcast and on-demand broadcast, has an advantage of adapting the requests of clients to a limited up-link bandwidth and following the change of data access pattern. However, previous hybrid broadcasting algorithms has a problem in the methods to get a grip on the change of data access Pattern. It is caused by the diminution of requests for the data items which are contained in periodic broadcasting schedule because they are already broadcasted. To solve this problem, existing researches may remove data items in periodic broadcasting schedule over a few cycles multiplying cooling factor or find out the requests of data items with extracting them on purpose. Both of them are the artificial methods not considering the property of data. In this paper, we propose a real-time adaptive hybrid broadcasting based on data type(RTAHB-DT) to broadcast considering data property and analysis the performance of our aigorithm through simulation study.

The authoring systems for digital contents using multimedia technologies ate requested in many fields such as education, medical science, entertainment market e-commerce and etc. Especially, the emergence of cyber universities and the rapid expansion of on-line education market require the effective contents authoring systems, which have various functions to generate the qualified contents. Therefore, many systems arc developed and currently used. However, since the developed systems considered only the developer's convenience, the generated digital contents by using these systems are failed to draw tile users'(or learners') active interaction with contents. That is, since the users just watch the contents like watching a drama or a film, it causes many problems in delivering the contents effectively or in evaluating the users. This paper presents, develops, and implements the new contents authoring system by using programing languages and/or software tools. The presented, developed, and implemented system mimics the face-to-face education in off-line system, induces the users' active interaction with contents, and continuous evaluation to the users.

Culture of Latin cultura culture derived from a translation of the original meaning of words was farming and cultivation, culture, art and later became the will of. British anthropologist E. B. Tyler book "primitive cultures, Primitive Culture" (1871) Culture in the "knowledge. Beliefs Arts. Morality. Law. Practices, including as a member of human society acquired the totality of skills or habits," he gave the definition. Culture can be seen in the human reason, of the form of action, not genetic thing by playing by learning to learn from the community and received the whole thing says. Thus, the prevalence of active cultural power of vigorous training is possible can. In this sense, our ceramic culture also reaffirming the importance of education and the reorganization is needed. Culture and what it takes to become a force larger than the act of teaching. Who supply the consumer with the culture and the sharing of feelings that can be read properly considering the skater to the consumer unless the formation of culture is impossible. In this regard, this study realized the importance of education and culture, as the current situation in our country and the activation of ceramic craft education is to provide.
