This study aims to investigate the specific functions of the five spirits based on the characteristics of five phases. In Korean medicine, the mind is classified into five spirits and seven emotions. The spirits (hon, sin, ui, baek, ji) are a way of analyzing of people's mental structures, and they are affected by each other, influencing life activities both directly and indirectly. They are also related to the five viscera and come into their own functions through the characteristics of the five phases that are assigned to the viscera. Sin is the main agent of mental activity that is normal, correct, and perfect, and it directs the other four. Hon is activity that is exposed to the outside from mental and physical aspects such as planning, creative thinking, creating, judgment, speech, and emotional expression. Baek is internal activity, such as obtaining information, learning, seeing, hearing, smell, taste, and touch. Ui is meant to decide between new and already saved information based on comparative analysis. Ji is the activity of making the final decision and saving it in ui. Based on the above, we suppose that the five spirits' functions match the characteristics of the five phases.

Maintaining a proper lookout activity routine is integral to preventing ship collision accidents caused by human errors. Various subjective measures such as interviewing, self-report diaries, and questionnaires have been widely used to monitor the lookout activity patterns of navigators. An objective measurement of a lookout activity pattern classification system is required to improve lookout performance evaluation in a real navigation setting. The purpose of this study was to develop an objective navigator lookout activity classification system using wearable accelerometers. In the training session, 90.4% accuracy was achieved in classifying five fundamental lookout activities. The developed model was then applied to predict real-lookout activity in the second session during an actual ship voyage. 86.9% agreement was attained between the directly observed activity and predicted activity. Based on these promising results, the proposed unobstructed wearable system is expected to objectively evaluate navigator lookout patterns to provide a better understanding of lookout performance.

Effects of nitric oxide and hypoxia on ethoxyresorufin deethylase in Hepa I cells and MCF-7 human breast cancer cells were examined. TCDD treatment have resulted in the stimulation of ethoxyresorufin deethylase activity based on fluorometry in Hepa I in dose and time dependent manner. 0.1 nM TCDD showed maximal stimulation of ethoxyresorufin deethylase activity and 24 hour treatment also showed maximal stimulation of ethoxyresorufin deethylase activity. In MCF-7 human breast cancer cells, untreated cells showed high basal level of ethoxyresorufin deethylase activity. TCDD treatment to MCF-7 cells resulted minor stimulation of ethoxyresorufin deethylase activity compared to that in Hepa I cells. Nitric oxide and hypoxia inhibit TCDD effects on ethoxyresorufin deethylase activity in both cell lines. And also flavonoids, such as quercetin showed an inhibition of ethoxyresorufin deethylase activity that is stimulated with TCDD or 3-Methylcholanthrene. Estrogen and estrogen metabolite such as 16 a-estriol and 2-hydroxyestradiol also affects the ethoxyresorufin deethylase activity in MCF-7 cells.

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.

고속철도 정차역은 시설현황, 정차역의 위치, 주변 토지이용 등 역세권 주변의 개발 정도에 따라 정차역에서 유발 및 유입되는 통행량에 큰 차이를 보이게 되며, 역과 역세권이 잘 발달된 정차역은 유동인구가 상당히 많음에 따라 특별구역(시설물)으로 정의되어질 수 있다. 이러한 특별구역은 많은 통행량을 발생시키는 토지이용 구역으로서 대학교, 공항, 대형쇼핑몰 등이 해당되어 왔으며 고속철도의 이용자가 증가함에 따라 정차역이 지역 내 통행수요에 미치는 영향을 고려하였을 때 특별구역으로 정의 될 필요가 있다. 지역내 교통처리 계획 및 연계교통계획 수립을 위해 특별구역에 대한 통행수요추정은 예전부터 상당한 관심이 요구되어 왔다. 그러나 전통적인 4단계 모형의 통행발생 및 분포 모형으로는 이러한 특별구역의 통행수요를 예측하는데 한계가 있으므로 개인별 통행행태를 고려할 수 있는 새로운 분석방법인 활동기반모형(Activity-Based Travel Demand Model)의 적용이 필요하다. 이에 본 연구에서는 고속철도 정차 역의 교통수요추정을 위해 활동기반 모형의 적용방안에 대하여 소개하며 향후, 적용가능성에 대하여 제시하도록 한다.

건설 프로젝트가 성공적으로 수행되기 위해서는 각종 제반 관리업무가 상호 밀접한 관계성을 유지하면서 프로젝트를 수행해야한다. 이중 공정관리는 인력, 자재, 장비, 원가 등 여러 가지 건설공사에 필요한 자원에 대한 관리업무를 시간적인 흐름 속에서 모델화 시킨 것으로, 공정관리의 원활한 수행은 프로젝트의 성공에 직접적인 영향을 주게 된다. 현행 공정관리 업무 프로세스에서 공사기간의 산정시 가장 중요하게 고려해야 할 점은 작업의 생산성은 투입되는 자원의 양과 질에 의해서 영향을 받으며, 이러한 자원의 특성은 투입비용으로 나타나게 된다는 것이다. 본 논문의 목적은 현장에서 사용되는 인력과 장비 등 자원투입 비용을 중심으로 생산성을 분석하고, 보다 현실성 있게 생산성 테이터를 공정계획의 수립시 작업기간 산정에 활용하는 방안을 제시하는 것이다. 본 연구에서 작업비용은 투입자원의 가격을 기준으로 산정했으며, 투입자원 비용과 작업량을 비교 ${\cdot}$ 검토하여 소요되는 작업기간을 예측한다. 이와 같은 공정데이터의 활용은 데이터베이스를 기반으로 하는 공정관리의 전 단계로써 자원투입 비용을 고려한 공정관리 방안을 제시하고, 이에 대한 타당성을 검토했다.

정보통신기술의 발전으로 교육분야에서도 시간, 장소 및 기기의 제약없이 학습이 가능한 스마트 교육이 활성화되고 있다. 그러나 주로 콘텐츠 기반의 교육 솔루션들이 제공되고 있고 학습자의 개별 특성을 파악하여 개별화된 학습을 제공하는 시스템 구축은 상대적으로 저조하다. 유아교육에서 자유선택활동은 중요한 놀이 활동이지만 교사들의 임상적 관찰에 의존함으로써 효율적으로 시행되지 못하고 있다. 최근 대두되고 있는 초연결성에 기반을 둔 사물인터넷 기술을 자유선택활동에 적용한다면 객관적이고 정형화된 데이터를 축적할 수 있고 이러한 데이터는 유아들의 개별화된 활동 유형과 놀이 형태 분석에 사용될 수 있을 것이다. 본 논문에서는 오픈소스 하드웨어 기반으로 사물인터넷 환경을 구축하여 유아들의 자유선택활동을 관찰하는 시스템을 설계하고 구현한다. 제안된 시스템은 유아들의 활동정보를 축적하여 분석 자료로 제공함으로써 교사들의 업무 경감과 개별 유아들에 대한 맞춤 교육 자료로 활용될 것이다.

In recent years, there has been a rise in epidemiological evidence suggesting the health benefits of a physically active lifestyle. However, it is not always easy for individuals to personally recognize the optimal conditions for exercise and physical activity. Wearable acceleration-based pedometers have become widely used in estimating the amount of physical activity, and to a limited extent, providing information regarding exercise intensity, but they have never been used to assess adaptation to exercise. In order to realize simultaneous activity monitoring for multiple users exercising outdoors, we developed a prototype wireless local area network (WLAN) based system. In our system, a WLAN is deployed outside, and a user wearing a smart phone and monitoring device exercises freely within the coverage area of the wireless network. By doing so, the developed system is able to monitor the activity of each user andmeasures various parameters including those related to exercise adaptation. In a demonstration experiment, the developed system was evaluated and used to monitor users enjoying a Nordic walk, after which users were immediately able to receive their exercise report. In this paper, we discuss the requirements and issues in developing an activity monitoring system and report the findings we obtained through the demonstration experiment.
