Chronic diseases management can be effectively achieved through early detection, continuous treatment, observation, and self-management, rather than a radar approach where patients are treated only when they visit a medical facility. However, previous studies have not been able to provide integrated chronic disease management services by considering generalized services such as hypertension and diabetes management, and difficult to expand and link to other services using only specific sensors or services. This paper proposes clinical rule flow model based on medical data analysis to provide personalized care for chronic disease management. Also, we implemented that as Rule-based Smart Healthcare System (RSHS). The proposed system executes chronic diseases management rules, manages events and delivers individualized knowledge information by user's request. The proposed system can be expanded into a variety of applications such as diet and exercise service in the future.

The purpose of this study was to investigate the caregiving and adaptation in families who awarded on filial piety. Using the qualitative methods-in depth interview genogram ecomap participation observation- 8 families were analyzed The major findings can be summarized as follows (1) These families showed very high family solidarity with strong collectivity. Their family role was interchangable and their familiarity was passed down from generation to generation. (2) Family members showed similar coping patterns on the basis of their own adaptationl Their coping was inclined toward acceptance especially religioous rather than emotional-focused ad hardly avoidance coping. (4) Although their economic emotional and service cares were family-centered with helps from their extended family household equipment for elder care was not prepared. (5) These families preferred to maintain this condition rather than to be well adapted. It was concluded that to help failed elder's family care iving social support program should be complemented in family life enrichment program for their children medical care program equipment rental program for elder in social network religion program and so on, Social norms forparent-children relation has be changed to more flexible care pattern. Also more social-emotional support has to be given to these families.

본 논문에서는 유비퀴터스 컴퓨팅 환경에서 다양한 어플리케이션 서비스를 개발하기 위한 필수적인 요소인 멀티미디어를 바탕으로 하는 단일화 된 어플리케이션 모델을 제안한다. 제안하는 모델의 유용성을 보이기 위해, 우리는 개발되어진 어플리케이션을 테스트하기 위해 유비퀴터스 네트워크가 가능한 ubihome을 구성하여 테스트를 실시하였다. 실험 결과에 따르면 우리의 실생활에 있어 다양한 멀티미디어 어플리케이션을 확장할 수 있다는 신뢰성을 주는데 무리가 없었다. 이것은 디바이스에 대한 독립적 신뢰성을 부여하여 보다 다양한 위치에서도 어플리케이션을 적용할 수 있다는 보여주기도 한다. 제안하는 시스템을 기반으로 원격지에서도 실시간 시스템을 통하여 위험한 지역에 있어서의 제어 및 감시에 도움을 줄 뿐만 아니라. 산업에 적용하여 산업재해를 미연에 방지할 수 있는 효과도 클 것으로 기대한다.

기존 감시 시스템은 제약된 공간내에서 감시 할 수 있어 보안 인력의 낭비와 고가의 시스템 설치비용이 소모된다. 이런 한계를 넘어 언제 어디서든지 필요에 따라 모바일 디바이스로 감시 서버에 접속하여 지정된 장소의 상황을 확인 할 수 있는 시스템을 구현하였다. 본 무선인터넷 기반 감시 시스템은 SKT-Service API 를 탑재하였고 삼성전자 SCH-X35O 무선단말기에 적용하였으며 PNG 파일 포멧을 적용하였으며 우수한 성능을 나타내었다.

지구관측데이터 공동활용체계로 GEOSS가 제안되면서 한국에서도 K-GEOSS 개발을 통하여 다양한 방식으로 지구관측데이터의 활용 확산에 참여하고 있다. 본 연구에서는 K-GEOSS 시범서비스로 환경 분야의 생물 종 분포 변화 예측 시나리오를 개발하여 미래 생물 종의 서식지 보호를 위한 지구관측데이터의 효과적 사용 사례를 보여준다. 이러한 시범서비스는 K-DMSS 플랫폼을 이용하여 개발하였으며, 데이터 수집 전처리, 모델 학습 평가, 실제 분포 변화 예측까지 모두 자동화하여 수행한다. 최종단에서 다양한 기후모델 및 기후변화 시나리오에 따른 여러 종류의 예측 결과를 제공함으로써 대체 서식지 보호 및 정책수립을 위한 종합적인 의사결정에 도움을 주도록 하였다. 이와 같은 다양한 종류의 시범서비스 개발 및 지구관측데이터의 공동활용 사례 발굴을 통하여 GEOSS 체계의 정착을 보다 앞당길 수 있다.

The purpose of this study was to explore how pre-service elementary school teachers participate in a course specifically designed to help them learn how to analyze instruction in terms of the levels of cognitive demand of mathematical tasks. This paper describes what prospective teachers learned while reading the cases of "implementing standards-based mathematics instruction", analyzing all tasks of one unit in one elementary mathematics textbook, observing master teachers' mathematics instruction as well as their colleagues during the practicum period, and developing their own cases on the basis of the design and implementation of instruction focused on mathematical tasks. This paper includes various reflections of the prospective teachers.

This study engages in the features of interaction in elementary school mathematics lessons as reflected in the class discourse. 28 pre-service teachers documented the discourse during observation of their tutor-teachers' lessons. Mapping the interaction patterns was performed by a unique graphic model developed for that purpose and enabled providing a spatial picture of the discourse conducted in the lesson. The research findings present the known discourse pattern "initiation-response-evaluation / feedback" (IRE/F) which is recurrent in all the lessons and the teacher's exclusive control over the class discourse patterns. Hence, the remaining time of the lesson for the pupils' discourse is short and meaningless.

The field application of acoustic emission(AE) testing for brand-new metal pressure vessel were performed. We will introduce the test procedure for acoustic emission test such as instrument check distance between sensors, sensor location, whole system calibration, pressurization sequence, noise reduction and evaluation. The data of acoustic emission test contain many noise signal, these noise can be reduced by time filtering which based on the description of observation during AE test.

This study is aimed at providing qualitative evaluation of information supplied by reference librarian in response to researchers' questions. Information users' satisfaction on the appropriateness of librarians' answers was evaluated, and at the same time, negative factors affecting users' satisfaction were examined, so that improvement of service quality and information appropriateness can be sought by analyzing the influences and correlation between these factors. For this study, information centers at ten professional research institute carrying out government-related projects were selected, and data were collected using unobtrusive evaluation methods through observation and questionnaires. Collected materials were analyzed using SPSS/PC+' statistical analysis programs and $\chi^2(Chi-square)$ statistical methods.

Precise Point Positioning-Real Time Kinematic (PPP-RTK) is a high accuracy positioning method that combines RTK and PPP to overcome the limitations on service coverage of RTK and convergence time of PPP. PPP-RTK provides correction data in the form of State Space Representation (SSR), unlike RTK, which provides measurement-based Observation Space Representation (OSR). Due to this, PPP-RTK has an advantage that it can transmit less data than RTK. So, recently, several techniques for PPP-RTK have been proposed. However, in order to utilize PPP-RTK techniques, performance analysis of these in a real environment is essential. In this paper, we implement the local network PPP-RTK and analyze the positioning performance according to the distance within 100 km from the reference station in Korea. As results of experiment, the horizontal and vertical 95% errors of local network PPP-RTK were 6.25 cm and 5.86 cm or less, respectively.
