Customer behavior pattern discovery is the fundament for conducting customer oriented services and the services management. But, the composition, need, interest and experience of customers may be continuously changing, thereof lead to the difficulty in refining a stable description of their consistent behavior pattern. This paper presented a new method for the behavior pattern discovery from a changing collection of customers. It was originally inspired from the swarm intelligence of ant colony. By the adaptive clustering, some typical behavior patterns which reflect the characteristics of related customer clusters can extracted dynamically and adaptively.

In this study, the concept of autonomous mobility is applied to a medical service robot. The aim of the development of the service robot is for the elderly assisting walking rehabilitation. This study aims that the service robot design parameter is proposed in ergonomic view. The walking assistant path pattern is derived from analyzing the elderly gait analysis. A lever is installed in the AMR in order to measure the pulling force and the leading force of the elderly. A lever mechanism is applied for walking assistant service of the AMR. This lever is designed for measuring the leading force of the elderly. The elderly adjusts the velocity of the robot by applying force to the lever. The action scope and the service mechanism of the robot are developed for considering and analyzing the elderly action patterns. The ergonomic design parameters, that is, dimensions, action scope and working space are determined based on the elderly moving scope. The gait information is acquired by measuring the guide lever force by load cells and working pattern by the electromyography signal.

Forecasting long-term mobile service demand is inevitable to establish an effective frequency management policy despite the lack of reliability of forecast results. The statistical forecasting method has limitations in analyzing how the forecasting result changes when the scenario for various drivers such as consumer usage pattern or market structure for mobile communication service is changed. In this study, we propose a dynamic model of the mobile communication service market using system dynamics technique and forecast the future demand for long-term mobile communication subscriber based on the dynamic model, and also experiment on the change pattern of subscriber demand under various scenarios.

본 연구는 소셜 뉴스 집적 서비스(Social news aggregation service)에서 뉴스의 수명주기 패턴을 카테고리 별로 분석하여 사용자의 관심 변화를 예측할 수 있는 통계적 모델 제시를 목적으로 한다. 인터넷 뉴스는 사용자의 관심이 단시간에 집중되며 시간에 따른 사용자 관심의 쇠퇴가 명확하게 드러나는 웹 자원으로, 사용자 관심 변화에 대한 다양한 연구가 현재 진행 중에 있다. 본 연구는 뉴스의 수명주기를 카테고리 별로 분석하여 사용자 관심의 쇠퇴 정도를 예측할 수 있는 통계적 모델을 도출하였으며 소셜 뉴스 서비스 제공자(Social news aggregator)의 콘텐트 게시 정책이 사용자 관심의 급격한 성장을 발생시키는 주된 외부적 요인임을 분석하였다. 본 연구에서 제안된 인터넷 뉴스의 수명주기 모델은 독자의 관심을 지속시키면서 다양한 콘텐트를 공급하려는 소셜 뉴스 집적 서비스에 유용하게 적용될 수 있다.

Background : The doctors' strike was not only a manmade disaster but also a chance to apply a new pattern of emergency medical service for patients. We hope to propose a new pattern of emergency medical service by comparing the patterns of emergency medical service given by resident and staff during the doctors' strike. Methods : We reviewed the medical records of patients who received emergency medical service in the Emergency Department(ED) of Deagu Catholic University Hospital during 3 days a week prior to the residents' strike (July 21-23, 2000) with those of patients receiving emergency medical service during the first 3 days of the residents' strike (July 28-30, 2000). We evaluated the patient's severity, the cause of the ED visit, the performance on the laboratory study, ECG, and radiological study, the disposition, and the length of ED stay. Also, we compared the collected data by presenting doctor and by patient's severity. Results : The staff performed fewer tests admitted fewer emergent and non-emergent patients than the residents. Also, the length of ED stay was shorter in both the emergent (212.76 vs. 321.40 minutes) and the non-emergent groups (117.68 vs. 171.39 minutes) for patients presenting to staff. Conclusion : It is desirable that emergency medical service is given by staff, not by resident.

This paper proposed the context awareness reasoning system to provide the personalized services dynamically in a ubiquitous mobile environments. The proposed system is designed to provide the personalized services to mobile users and consists of the context aggregator and the knowledge manager. The context aggregator can collect information from networks through Open API Gateway as well as sensors in a various ubiquitous environment. And it can also extract the place types through the geocoding and the social address domain ontology. The knowledge manager is the core component to provide the personalized services, and consists of activity reasoner, user pattern learner and service recommender to provide the services predict by extracting the optimized service from user situations. Activity reasoner uses the ontology reasoning and user pattern learner learns with previous service usage history and contexts. And to design service recommender easy to flexibly apply in dynamic environments, service recommender recommends service in the only use of current accessible contexts. Finally, we evaluate the learner and recommender of proposed system by simulation.

고속철도(HSR)의 운영은 집적이익에 영향을 미치며, 개별 경제활동들은 경제적 이익을 극대화할 수 있는 곳으로 이전한다. 이러한 측면에서 볼 때, 고속철도역과의 인접성은 고속철도 네트워크를 통한 이익 극대화를 영위할 수 있는 핵심구역으로 간주할 수 있다. 본 연구에서는 GIS를 이용한 한국과 일본의 서비스 산업 핫스팟 분석을 통해 고속철도역 주변에 대한 집적효과를 분석하고자 하였다. 한국과 일본의 집계구 데이터를 활용하여 분석을 수행하였으며, 일정 규모 이상 도심에 위치하고 있는 고속철도역이 입지하고 있는 한국 8개, 일본 큐슈신칸센 4개역을 대상으로 하였다. 분석결과 구포역과 카고시마츄오역 등 2개 역을 제외한 나머지 10개 역들 반경 1km 이내에서 서비스산업의 집적이 관측되었다. 여가, 레저, 협회 및 특정 전문 서비스산업들의 경우 고속철도승객을 통한 관광객 유입 혹은 지식교류 등의 효과를 영위함으로써 사회경제적 이익을 얻을 수 있다. 이를 고려했을 때, 역 주변에 대한 핫스팟의 도출은 역 접근성과의 관련성을 보여줄 수 있을 것이다. 분석결과를 정책적으로 보았을 때, 향후 역 주변 개발에 있어서 서비스 산업과 관련 산업들의 사회경제적 이익을 극대화할 수 있도록 지원 또한 필요할 것이다.

Objectives : The purpose of this study was to investigate the relationship between dietary pattern and the Community Periodontal Index in elderly people who live alone in rural areas and to provide necessary data to strengthen nutrition education about the oral health of elderly people who live alone. Methods : Dental examinations and questionnaires were conducted with 380 elderly people who live alone in rural areas of Gyeonggi-do. Results : The Community Periodontal Index was higher when the elderly people who live alone had a low intake of vegetables and fruits, a high intake of sugars, a low number of breakfasts, a high frequency of overeating and a high frequency of instant ingestion. Conclusions : It is necessary to provide nutritional management services for the elderly people who live alone in rural areas and to provide preventive centered comprehensive oral care.
