Smoke is one of the most critical factor when escaping from the fire since it reduces visibility and interrupts finding emergency exit lights. Therefore, it is recommended that an evacuation simulation program should incorporate the smoke factor. In addition, it is suggested that the program should include not only the unilateral damage by the smoke but also the detour evacuation by risk communication. In this study, MAS (Multi Agent System)-based simulation program which incorporates the reduced walking speed by smoke and adopts the dispersion evacuation logic during escaping from the fire. To make comparison, a commercial evacuation program, Pathfinder was used. It was found that the simulation results of MAS (Multi Agent System)-based program is better than Pathfinder in terms of safe evacuation. It means that evacuation simulation need a additional evaluation categories that include not only quick evacuation time but also safe evacuee number.

An agent is a computer program that acts autonomously on a computer system. A mobile agent is not bound to the system where it begins execution. It has an ability to transport itself from on e system in a network to another. Mobile agent system solve the network traffic problem. Moreover, the agent may utilize the object services of the destination agent system. In this study the mobile agent system is introduced to support security service.

최근 에이전트를 교육에 활용하려는 연구와 노력이 시도되고 있다. 에이전트는 컴퓨터가 사용자를 대신하여 주어진 일을 수행하는 대행자(proxy)나 중개자(middle ware) 역할을 하는 컴퓨터 프로그램을 통칭하는 개념이다. 근래에 다양한 장르에서 에이전트가 활용되고 있으며 교수 학습 분야 역시 그러한 것 중에 하나에 해당된다. 웹 상에서 교사의 역할을 대신할 수 있는 프로그램이나 엔진의 개념이 교수 학습을 지원하는 웹 에이전트이다. 웹 상에서 에이전트는 교사의 역할을 수행할 뿐만 아니라 학습자를 도와 주는 도우미 역할을 수행한다. 웹 에이전트가 적용된 웹 기반 교수 학습 환경은 학습자나 교사에게 적응적이고 개별화된 환경을 제공한다.

Three vat dyes have been applied to regular viscose rayon and their dyeing and wash fastness properties were evaluated. Particle size determination was undertaken to obtain information about the size of dye particles converted by a reducing agent, to see if dye particle size has an affect on dyeing properties of regular viscose rayon. It is observed that viscose rayon exhibits more dyeability with reducing agent concentrations between 5-7.5 g/l. Also, we found that the vat dyeing system is greatly affected by the particle size of the vat dye converted to leuco form by a reducing agent.

본 논문에서 오픈 소스 하드웨어인 아두이노 기반의 스마트 온실관리 시스템 모델을 제안하고 구현하였다. 제안된 스마트 온실관리 시스템은 센서 및 아두이노 등으로 구성된 제어 장치부, 온실 제어를 담당하는 에이전트(Agent) 프로그램, 사용자 API를 담당하는 웹 어플리케이션 등으로 구성되어 있다. 제어장치부는 온도, 습도, 광조, 수분 센서 데이터를 에이전트 프로그램으로 전송하고, 에이전트 프로그램은 데이터를 DB에 저장하거나 사용자의 제어 값을 제어장치부에 전송한다. 사용자는 웹을 통해 온실의 센싱 정보를 확인하거나 각종 액츄에이터 (Actuator)를 원격 제어할 수 있다. 또한 제안 시스템의 상황 인지 및 자율 제어 기능을 통해 스마트한 온실 관리가 가능하다. 구현 결과, 제안된 온실관리 시스템 모델이 잘 동작함을 확인할 수 있었다.

In this research, we are trying to develop a framework to evaluate the prevention program for Tsunami disaster based on the Multi-agent simulation model. Tsunami has arisen by the earthquake. It happened after flew minutes or few hours when it occurred. It is clear that Tsunami will come after earthquake and from seashore. If we prevent the damage by Tsunami, we should make people who is in the seashore and lived near the seaside escape from there. Moreover we must forecast the escape activity from Tsunami. Former research of this field, some researches try to forecast the escape activity as macro level. However, people who escape from Tsunami is differ from their physical ability and ability of information processing. It needs a more accuracy model to forecast the escape activity of them. Furthermore they make a decision step by step using the various information. Therefore escape activity from Tsunami will describe using an agent based model which can only treat the information processing of human being. In this paper, we develop the evacuation model from Tsunami disaster using the Multi agent based model. The purpose of this study is to analyze the human action pattern when Tsunami occurred, and to make an accurately assessment for damages by Tsunami. The Fujisawa city government is planning and operating the various prevention program far Tsunami. However nobody assess it, because they do not have any simulation models for Tsunami disaster. If they want to set an effective prevention program for Tsunami, they should have any kinds of simulation model. The results of this study are 1) To develop the Multi agent based evacuees escape activity model. 2) Assess the damage of Tsunami in Fujisawa-City.

Forming health care management model in small-scale enterprises was the purpose of this study. For the purpose, we tried to investigate the characteristics of small-scale enterprises and analyzed the pattern of their health care management. The results are as follow: 1. The strength of health managing agency and technical supporting program lies in team approach by specialized manpower. However, if the liaison between each part of the organization is not smooth, the overall management will be very difficult. 2. Small scale enterprises are characterized by their short life after the establishment, use of rental building, lack of welfare facilities, weakness in sanitary management and aggregation of factories of similar type of industry. Because of these characteristics, it is very difficult to solve problem basically, such as improvement of working environment. Therefore, it is important to focus on health education and community based approach. 3. Many workers in small-scale factories are in middle and old age. They have health problems mainly related to personal habits. Implementation of an appropriate health promotion program is needed. 4. The number of workplaces, which should be managed by health managing agent. is increasing rapidly. But the number of health managing agent is limited. In the aspect of the requirement of manpower and equipment, training personal agent is more urgent than founding institutional agent. 5. The uniform method of health management hampers the choice of employer and workers. The types of provision of health management should be diversified. 6. For an efficient management, a frequent visit of personal agent and the following referral to a specialist should be done. The specialists in charge of secondary management are from the field of occupational medicine, occupational hygiene, ergonomics, etc. 7. The health management of small-scale facilities should have six components. They are community-based approach, multi-disciplinary cooperative system, program based on the need of recipient, forming partnership of employer and worker, change of lifestyle, and evidence-based program.

Purpose: The purpose of this study was to identify the effects of a multi agent obesity control program in obese school children. This program was composed of strategies to modify diet and exercise habits and to change cognitive behavior variables(stress, coping, and self-efficacy). Method: The subjects were 40 obese school children who participated in our project voluntarily via homepage, TV, newspaper, public paper and school official documents. The program was implemented daily for 4 sessions per day for ten days from August 16 to 26, 2004. The daily program consisted of exercise therapy, dance therapy, cognitive behavior therapy and aroma therapy. The data was analyzed by paired t-test using the SPSSWIN program. Result: There was a significant decrease in children's waist-hip ratio(p=.04) and in children's stress(p=.00) after the program. There was a significant increase in children's self-confidence after the program(p=.02) and a significant decrease in children's diet habit after the program(p=.02). Conclusion: This study provides evidence that a multiagent obese control program is effective in changing waist-hip ratio, stress, self-confidence, and diet habits in obese school children.

지능형 방송 서비스는 시청자의 방송 프로그램 선호도 및 프로그램 관련 정보를 기반으로, 사용자가 원하는 방송 프로그램을, 원하는 때에 원하는 형태의 프로그램으로 제공하는, 새로운 방송 환경을 의미한다. 이러한 지능형 방송은 맞춤형 방송 또는 personal casting 방송환경을 제공하며, 미래의 사용자 중심의 방송에 근간으로 자리잡을 것이다. 본 논문에서는 소프트웨어 에이전트 국제표준화 단체인 FIPA(foundation fur Intelligent Physical Agents)의 에이전트 프레임워크를 이용하여 에이전트 기반 개인형 맞춤 및 지능형 멀티미디어 방송 프레임워크 구축에 대한 연구 결과를 제안한다. 방송프로그램 서버 에이전트와 사용자 단말 에이전트 사이의 통신(메시지 교환)은 FIPA 에이전트 통신 언어인 Agent Communication Language를 이용하였으며 사용자 취항 정보는 MPEG-7 MDS(Multimedia Description Schemes)의 사용자 선호도 기술구조(user preference description scheme)를 따랐다.
