Activity-based models analyze individuals' various daily activities that are identified as a decision-making unit for transportation planning. In other words, it is the model that determines the types of activities according to the social, economic and situational characteristics of the groups with the same activity patterns and predicts individuals' activity time, distance, spatial movement and transportation mode. The activity-based model is a method of estimating more efficient and realistic demand in transportation forecasting because traffic is regarded as a complex decision-making process that an individual and other people participate in. In this paper, we grasp the factors affecting choice behavior of activity pattern and analyze choice behavior of activity pattern based on multi-dimensional characteristic of each person. First, we classify activity types of reviewing the trip chain and activity purpose. Next, we identified preferable activity types using complicated characteristics of main agent of activity. We concluded that choice behavior of activity pattern is dependent on complex characteristics of each agent, and further multi-dimensional characteristics of each person are affected over the whole decision process of activity schedule.

Objective : The purpose of this study is to measure the level of activity possessed by the daily activities of the elderly. In addition, we attempted to compare the differences in the categories of daily activities. Methods : We used K-ACS to evaluate 30 older people who engaged in economic activity living in community, 30 older people who did not have economic activity living in community, and 30 older people living in facility. We compared the level of activity retention. Results : There was a significant difference of level of activity retention according to the daily activity category of the subjects(p <.001). There was a difference in the instrumental activities according to the category of each activity, while the three groups showed similar patterns in leisure activities and social activities. In particular, all three groups were most likely to rest and watch television in the leisure activities, so the leisure activities of the elderly in Korea were very limited. Among the general characteristics, it was analyzed that there was a correlation between the activity, the marital status, the religion and the cognitive level. Conclusion : According to the daily activities category of the elderly, there was a difference in level of activity retention and the characteristics of daily activities correlated with the activities of the elderly. This suggests that it may be a basic data for establishing a client - centered intervention plan by considering the characteristics affecting daily living and level of activity retention of the elderly in the occupational therapy.

Focusing on open innovation which is regarded as an important framework for strengthening technological innovation capabilities, in this study empirical analysis is conducted on Korean manufacturing companies, particularly based on the survey results of 149 domestic manufacturing companies that carry out innovation activities in order to identify influence factors for open innovation activities. Analysis on the influence factors of open innovation activities categorized into characteristics of environment, firm-specific characteristics, and characteristics of institutions revealed that characteristics of environment in terms of the degree of market competition and technological changes influence outside-in open innovation activities. Such results suggest that companies respond to increased market competition or technological changes by promoting research and development (R&D) and maintaining or acquiring market competitiveness through introduction of external technology and utilization of external information by means of research collaboration, user innovation, and so on. In terms of firm-specific characteristics, outside-in open innovation activities are influence by R&D personnel, R&D investment, number of international business, export, and openness of corporate culture while inside-out open innovation activities are influenced by characteristics of international organization and CEO's capabilities. In order for companies to strengthen outside-in open innovation activities emphasis on research personnel, R&D input factors such as research funds are necessary whereas to increase inside-out open innovation activities organization solely responsible for international affairs should be established while the CEO needs to focus on open and cooperative entrepreneurship rather than internal technological innovation activities. In terms of characteristics of institutions, outside-in innovation activities are influenced by technological networking whereas inside-out innovation activities are influenced by networking for development of technology and the presence in industrial cluster. This means that the government needs to establish industrial clusters and try to expand technological networking to facilitate open innovation activities.

Korea has been suffering from financial hardship with low birth rate and rapid growing of advanced aged people because low economic growth and low interest rate have continued after IMF foreign-exchange crisis. Under these circumstances, it is necessary for the middle-aged people to have well-prepared retirement plan in the sense of physical, psychological, social and economical preparedness. The study intends to find out how the occupation and activity characteristics affect the physical, psychological, social and economical preparation for their remaining old age. For the purpose, questionnaires were collected from 344 middle-aged people working in private companies, public offices and small-business owners in metropolitan and Chungcheong province. The findings are as follows: First, they were physically well-prepared, as they thought their leisure activity was more important, their occupational role was more stable and they were old and healthy. Second, Women had notion about their occupation if they kept a good relationship with their colleagues. And they were psychologically prepared well as they valued their leisure activities. Third, if they perceived their occupations as stable and had more social and leisure activities, they were socially well-prepared. Fourth, Although the level of economical preparation depends on their wealth, the occupation and activity characteristics had no effect on the economical preparation. These findings imply that the retirement preparation as a recent social issue has been influenced by the nature of occupation and activity and suggest that the definite policy and program will be required for the retirement preparation of the middle-aged people from various aspects.

Urban transport demand is derived from activity participation. A variety of individual daily activities based on the decisions on activity participation result in collective spatial behavior. The travel derived from the effort to overcome the spatially distributed locations of adjacent activities represents the detailed structural relationships among activities. An activity-based approach provides an important framework of analyzing contemporary urban daily life in the sense that it studies the interaction between individuals' daily decision making and social practice in time and space, on the one hand, and socio-spatial environment on the other. The current study identifies representative patterns of urban daily activity implementations and analyzes the correlation between representative patterns and individuals' characteristics and contextual characteristics. The study shows that urban daily activity patterns can be grouped in a limited number of representative patterns, which are systematically correlated with socio-spatial characteristics. The results provide related transportation policy implications.

웹을 기반으로 하는 e-러닝에 대한 교육적 수요는 증가하고 있다. 이와 동시에, 학습 공간으로서의 사이버 공간의 활용에 대한 고민도 증가하였다. 전통적인 학습활동을 사이버 공간에 복제하려 했던 고전적 방식이 e-러닝 또는 사이버 학습이 아니라는 사실을 확인하기 시작했기 때문이다. e-러닝의 가치가 강조됨에도 불구하고, 실제 사이버 공간에서 일어나는 학습자의 특성과 학습활동이 구체적으로 어떻게 일어나는 지에 대한 탐색은 미흡하다. 산재한 정보를 스스로 가공한 지식, '학습하는 방법을 학습'하는 것이라는 개념들이 제시됨에도 불구하고, 사이버 공간에 산재한 정보, 학습하는 방법의 학습, 그리고 사이버 공간의 학습특성에 대한 논란은 여전하다. 본 연구에서는 실제 사이버 학습 사이트를 이용하고 있는 학습자들의 행동을 중심으로, 학습자의 특성을 탐색하였다. 사이버 공간에서 보이는 스스로 학습하는 방법이 무엇인지 확인하고 이것이 다양한 학습자 유형으로 구분되는 지를 확인하고자 하였다. 연구대상이 된 사이버 학습 사이트는 서울, 부산, 대구, 광주 교육청에서 운영하는 사이버 가정 학습관이었다. 총 1535명의 사이버 가정 학습관 이용자들의 특성이 분석되었다. 사이버 가정학습관 이용자들의 행동특성은 9개의 요인-놀이 활동, 공동 경험, 현실 정체, 공동 성취, 개인주의, 경쟁 지향, 성취감, 편리성(조작 용이), 생생함-으로 구분되었다. 9개의 활동 요인을 기준으로 하여 확인된 학습자 유형은 4가지로 나타났다. 4가지 학습자 유형은 각각 독야청청형, 동고동락형, 의무방어형, 희희낙낙형으로 명명되었다. 이들 유형은 학습 활동 정도 및 사이트 이용 행동, 학습 스타일(사이버 학습 활동 양식)에서 서로 차이가 있었다. 본 연구는 기존의 이론적인 모델에 기초하여 임의적으로 구분된 사이버 학습자 유형 구분이 아닌, 실제 학습 활동을 탐색하였다는 측면에서 의미가 있다. 특히, 기존의 오프라인 학습 이론 및 학습자 특성 연구를 사이버 학습에 그대로 적용할 것이 아니라 사이버 공간의 특성이 실제 학습 활동에서 어떻게 나타났는지를 밝히려고 했다는데 그 의의가 있다. 향후, 사이버 학습자 유형에 따른, 사이버 학습활동의 촉진방안이나 학습 효과의 차이를 높일 수 있는 구체적인 학습 시스템의 설계 및 운영 모델에 대한 탐색이 필요할 것이다.
