Personalized reminder systems have to identify the user's current needs dynamically and proactively based on the user's current context. However, need identification methodologies and their feasible architectures for personalized reminder systems have been so far rare. Hence, this paper aims to propose a proactive need awaring mechanism by applying agent, semantic web technologies and RFID-based context subsystem for a personalized reminder system, which is one of the supporting systems for a robust ubiquitous service support environment. Rescorla-Wagner model is adopted as an underlying need awaring theory. We have created a prototype system. called NAMA(Need Aware Muiti-Agent)-RFID. to demonstrate the feasibility of the methodology and of the mobile settings framework that we propose in this paper Moreover, to test if the proposed system works in terms of scalability, a simulation was performed and the results are described.

Purpose: This study was aimed to develop a computerized reminder system and evaluate it's effect in terms of percent age change of screening, and satisfaction. Method: It was conducted through 6 phases: Analyzing the job and defining the basic input data, developing the information system, collecting and inputting data, testing the system, working with the system, and evaluating it's effect. Participants were 787 people (female 30-69 years, and males 40-49 years) in 2 dong of Suyoung gu, Busan, who haven't had cancer screening for the stomach, breast, or cervix since Dec. 2000. There were three experimental groups: a letter; calling and calling after the letter reminder, and a non-equivalent control group. To determine whether services were obtained, a telephone survey was done after two months of follow-up. Result: A cancer screening information system with five DB modules was developed. Overall compliance with screening was not statistically significantly changedbefore and after applying computerized reminders for all three screening sites. Only 16% were satisfied with the reminder. Conclusion: This data didn't show that a reminder effort was effective of screening. However, because the evaluation interval was too short to find a difference in screening rate, we recommend additional longer prospective follow up studies.

Personalized reminder systems have to identify the user's current needs dynamically and proactively based on the user's current context. However, need identification methodologies and their feasible architectures for personalized reminder systems have so far been rare. Hence, this paper aims to propose a proactive need identification mechanism by applying agent and semantic web technologies and RFID-based context subsystem for a personalized reminder system, which is one of the supporting systems for a robust ubiquitous service support environment. We have created a prototype system, RFID-based NAMA (Need Aware Multi-Agent), to demonstrate the feasibility of the methodology and of the mobile settings framework that we propose in this paper. NAMA considers the context, user profile with preferences, and information about currently available services, to discover the user's current needs and then link the user to a set of services, which are implemented as web services.

An early warning system was developed to help identify stock status as early as possible. For performance to improve, there needs to be a feature to predict the amount of stock that must be provided and a feature to estimate when to buy goods. This research was conducted to improve the inventory early warning system and optimize the Reminder Block's performance in minimum stock settings. The models used in this study are the single exponential smoothing (SES) method for prediction and the economic order quantity (EOQ) model for determining the quantity. The research was conducted by analyzing the Reminder Block in the early warning system, identifying data needs, and implementing the SES and EOQ mathematical models into the Reminder Block. This research proposes a new Reminder Block that has been added to the SES and EOQ models. It is hoped that this study will help in obtaining accurate information about the time and quantity of repurchases for efficient inventory management.

In this paper, we propose a medication reminder system using IoT platforms and products to help old adults keep track of their medication schedule, one of 10 Korean instrumental activities in daily living (K-IADL). An interworking architecture based on the oneM2M standard platform is designed to allow various IoT products to be connected each other through interworking proxy entities. A prototype system for the medication reminder service is developed, which consists of a pair of off-the-shelf pill bottle and container box embedded with an NFC tag and reader respectively, three types of actuators including a LIFX LED lightbulb, Musaic speaker, Microsoft Band 2, and smartphone applications. The experiment shows that our medication reminder system can make alarms for old adults to take their pills appropriately considering where they are and when they have food inferred from data collected from sensors including ultrasonic sensor and rice cooker, fostering them to keep their medication routine.

Developing a personalized system on a user's behalf which is working around the Internet-based marketplace is one of the challenging issues in intelligent e-business, especially mobile commenrce. It has been highly recommended that such a mobile personalized system has to perceive the user's needs a priori by tracking user's current context such as location with activity and then to identify the current needs dynamically and proactively. Automatically and unobtrusively getting user's context is an inevitable feature for the development of autonomous mobile commenrce. However, personalization methodologies and their feasible architectures for context-aware mobile commerce have been so far very rare. Hence, this paper aims to propose a context-aware mobile commerce development methodology by applying agent and semantic web technologies for personalized reminder system, which is one of the mobile commerce support system. We revisited associationism to understand a buyer's need identification process and adopt the process as 'purchase based on association' to implement a personalized reminder system. Based on this approach, we have showed how the agent-based semantic web service system can be used to realize need-aware reminder system. NAMA(Need-Aware Multi-Agent), a prototype system, has been implemented to show the feasibility of the methodology and framework under mobile setting proposed in this paper. NAMA embeds bluetooth-based location tracking module and identify what a user is currently looking at through her/his mobile device such as PDA. Based on these capabilities, NAMA considers the context, user profile with preferences, and information about currently available services, to aware user's current needs and then link her/him to a set of services, which are implemented as web services.

개인화된 상기 시스템은 사용자의 현재 상황 정보를 토대로 현재 욕구를 동적이며 선응적으로 파악하여야 한다. 하지만 기존의 욕구 인식 방법론 및 상기시스템 아키텍처들은 이러한 요구 사항을 잘 반영하지 못해왔다. 따라서 본 논문은 에이전트, 시맨틱 웹, 그리고 RFID기반의 상황인지를 활용한 선응적인 욕구 인지 메커니즘을 유력한 유비쿼터스 서비스 지원환경의 하나인 개인화된 상기 시스템에 적용하는 것을 목적으로 한다. 이를 위하여 주된 욕구 인지 이론으로 Rescorla-Wagner 모형을 채택하였다. 또한 본 논문에서 제안하는 방법론의 실현 가능성을 보이기 위해 NAMA (Need Aware Multi-Agent)-RFID라고 하는 프로토타입 시스템을 개발하였다. NAMA는 사용자의 욕구를 인지하기 위해 상황 정보 및 사용자 프로파일과 선호도, 가용 서비스 관련 정보 등을 고려할 수 있으며, 웹 서비스의 형태로 구현된 서비스 집합들을 사용자에게 연결시켜준다. 더욱이 범위성 측면에서의 시스템 성능을 보이기 위해 시뮬레이션을 수행하였으며, 그 결과를 보였다.

Recently, there has been a rapid increase of interest in u-Health systems or instruments. The importance of testbeds has been discussed deeply also. However, beyond laboratory or ward environments, testbeds covering metropolitan area cannot be found easily. Moreover, there has been few papers which discuss the results of testbed operations for various instruments in different age groups. In this paper, the results of testbed which operated in Daegu metropolitan area are discussed and improvement directions to strengthen the competitiveness are proposed using user analysis. In particular, the results of trial services using the u-Life support instruments (medication reminder, falling safety phone, bio-patch and shirts, etc) for super aging societies in the near future are discussed.

의료기술의 발달로 인해 세계적으로 평균 수명이 늘었으며 그에 따라 노인 인구가 증가되고 있다. 2018년 기준 한국은 이미 고령사회로 진입을 하였다. 노령화에 따른 기억력 저하 등의 이유로 복약이 어려운 경우가 많다. 기존의 경우 단순히 복약할 시간에 대한 알림만 주는 경우가 많았다. 그에 따라 본 논문은 아두이노를 이용하여 약품 복용 알림 시스템을 구현하였다.
