The conventional four-step travel demand model is still widely used as the state-of-practice in most transportation planning agencies even though it does not provide reliable estimates of travel demand. In order to improve the accuracy of travel demand estimation, implementing an alternative approach would be critical as much as acquiring reliable socioeconomic and travel data. Recently, the role of travel demand model is diverse to satisfy the needs of microscopic analysis regarding various policies of travel demand management and traffic operations. In this context, the activity-based approach for travel demand estimation is introduced and a case study of developing a spatial-temporal activity presence-based approach that estimates travel demand through forecasting number of people present at certain place and time is accomplished. Results show that the spatial-temporal activity presence-based approach provides reliable estimates of both number of people present and trips actually people made. It is expected that the proposed approach will provide better estimates and be used in not only long-term transport plans but short-term transport impact studies with respect to various transport policies. Finally, in order to introduce the spatial-temporal activity presence-based approach, the data such as activity-based travel diary and land use based on geographic information system are essential.

With the turn of the 21st century, corporate legitimacy is at risk. The society is demanding even greater responsibility to the corporations in return of exercising its enlarged influencing power. As the legitimacy is threatened, entrepreneurial activities have become even more important than ever in order to obtain trust from the public and to be accepted as an ethical enterprise. This study assumes corporate legitimacy as the necessary element in overcoming the crisis. With this respect, it further states what kind of effect the exercise of corporate reputation and social responsibility have on ensuring corporate legitimacy in crisis. To verify the purpose of this study, two research hypotheses and one research question were set. The major research results and the implications are as follows. First, the corporate reputation of Samsung Heavy Industries affects the corporate actional legitimacy in case of crisis. Second, recognition on corporate legitimacy varied in accordance with the public’s perception of the corporate social responsibility. Third, the interaction between corporate reputation and social responsibility plays a role in determining corporate legitimacy. This result denotes that it is necessary to exercise social responsibility and build up corporate reputation in order to obtain corporate legitimacy in crisis.

This study attempts to analyze the spatial disparity between supply and the demand of volunteering activities in Daegu, South Korea. The spatial disparity of volunteering activities has been strongly influenced by the residental disparity in terms of socio-economic level. The ratio of volunteers is mostly determined by income and education level that strongly impact the spatial distribution of residential area. The regional difference of ratio of volunteers is greater among Gu districts than in Dong level. The recipients for the volunteering activities have been likely to reside in a particular area within a Gu district; so, regional difference of the recipients was severe in dong level rather than Gu level. It is strongly recommended to exchange volunteers among regions to reduce the spatial disparity between the volunteers and the recipients.

This study attempts to introduce the methodology for accounting real-time population distribution in the urban areas. For the purpose, we utilize the media user's time-space information from the media users' media diaries in the media panel survey databases. We analyze the space-time population rate for each activity space related with everyday urban lifes. Seoul has been selected as a case study area, since space-time information are relatively rich there, and thus the comparisons are available. The space-time population rates have been verified by the comparative analysis with the T-card results. We propose a real time population measurement method by combination of the space-time population rate with geographical data. The real time population of each activity space at each dong in Seoul has been calculated by multiplying the space-time population rates to the numbers of employer of three categories of activity spaces(residential, working, and commercial). By utilizing GIS, we visualize the results of two time points (3AM and 3PM) and then analyze the spacio-temporal characteristics of real time population distribution in Seoul. The Day time population distribution pattern shows strong relationships with the distribution of business and commercial activities, while the night time population distribution pattern can be explained by resident population distribution almost perfectly.

Objective: The purpose of this study is to examine the factors influencing the health status of first-year high school students leisure activity time, considering of the city size. Methods: This study utilized the first cohort survey of the Korean Children and Youth Panel Survey. The analysis was used data from survey targeting first-year high school students of 2021. The city size was divided into large cities and medium and small-sized cities, and T-test was conducted to examine differences in factors by city size, and multiple regression analysis was conducted to identify factors influencing health status according to leisure activity time on weekdays and weekends by city size. Results: In large cities, exercise and physical activity time and other than that, Time to play with friends had a positive effect(+), Time to play with a smartphone had a negative effect(-) on both weekdays and weekends. In medium and small-sized cities, Exercise and physical activity time and Time to play while watching TV had a positive influence(+) on both weekdays and weekends, while Time to play with a smartphone had a negative influence(-). Conclusion: There were the same questions for factors influencing health status, but other questions also appeared. Leisure activities that have a positive(+) impact on health status by city size are supported so that leisure activities can be actively carried out, while leisure activities that have a negative(-) impact are participate in other leisure activities together to improve health. It is believed that this plan should be considered.

This study proposed an approach of clustering collective users' activities of location-based social networks using check-in data of Foursquare users in Seoul. In order to cluster the collective activities, we generated sequential rules of the activities using sequential rule mining, and then constructed activity networks based on the rules. We analyzed the activity networks to identify network structure and hub activities, and clustered the activities within the networks. Unlike previous studies that analyzed activity transition patterns of location-based social network users, this study focused on analyzing the structure and clusters of successive activities. Hubs and clusters of activities with the approach proposed in this study can be used for location-based services and marketing. They could also be used in the public sector, such as infection prevention and urban policies.
