Recently, urban and transportation planning for Transit Oriented Development(TOD) has become a major issue. For the effective policy implementation of TOD, it is important to understand the travel behavior of residents in housing areas. In this study, we compared the travel behaviors of residents by housing types based on 'the 2010 Household Travel Survey Data' focusing on metropolitan areas. By building an estimation model for subway trip frequency by housing types, it was identified that the factors influencing subway trips and ultimately suggested implications to increase the use of the subway. The highest share of bus mode was for detached house residents with 22.8%, whereas the share of subway mode was highest by efficiency apartment residents with 17.5%. Walking distance to the subway from efficiency apartment and row house were verified as 661meters and 749meters. As the residents of each housing type have more cars and bicycles, their subway trips were decreased. It was also found that subway trips were increased when the population density of residence was high with good accessibility to subway stations and poor accessibility to bus service. In this study, the statistical findings to differentiate the planning factors of public transportation by housing types were also provided. The results of this study would be used for urban design considering the travel behaviors of residents by housing types and can also be utilized for promoting the patronage of public transportation. Some limitations and a future research agenda have also been discussed.

This research was conducted to find out about the effects of a perceived usefulness and a perceived ease of use on the viewer's attitude and their intention to use of the Terrestrial UHD Broadcasting. The survey was conducted with 191 respondents while innovativeness, relative advantage, active engagement, accessibility and affinity were considered as the external variables for this research. As the result shows, the external variables that affect the perceived usefulness are affinity, relative advantage, and innovativeness. However, it was confirmed that the accessibility has no major effect on the perceived usefulness. Among the external variables, the innovativeness has the highest level of effectiveness on the perceived usefulness of UHD broadcasting. Relative advantage, active engagement, and affinity were followed in orderly fashion. Especially, the perceived ease of use on UHD broadcasting has a major effect on the perceived usefulness. Also, the perceived usefulness affects the viewers' attitude and their intention to use. And the research verified that there is no correlation between the perceived ease of use vs. attitude and between attitude vs. intention to use. Therefore, we can safely say that the perceived usefulness of UHD broadcasting has main effects on viewers' attitude and their intention to use of UHD broadcasting.

This study reports a field study that examined the citizens' needs and perceptions of library services at a municipal public library system of Mapo-gu, in an attempt to develop a comprehensive service plan that can satisfy the diverse public needs in the changing social environment. We administered a self-reported questionnaire to 800 library users and 300 non-users in the area to examine their reading habits, library use, and perceptions of library services and programs. As a result of the analysis, 53.7% of Mapo-gu residents used one or two libraries among all 16 municipal libraries, and the primary criterion for selecting the main library was accessibility(63.9%). And only 53.8% of library users had experience participating in the library programs. The respondents also showed strong perception that the library is an essential place for the community and the children. Study results indicate that the library system should further expand the collection size, diversify information contents, improve the physical space including library facilities, and build more libraries. In order to fulfill the role of public libraries as the central place of the community, the municipal city should further invest in enhancing accessibility, spatial innovation, and diversifying service contents and media.

Rapid urbanization has resulted in the unprecedented growth of population in Metro Manila, the Philippines and has led to a 'dual' housing crisis - vacant/unoccupied socialized housing and a chronic housing shortage or delayed housing supply. By developing two GIS-based statistical models, this study is to examine socialized housing in comparison with private housing with respect to location patterns, integration, accessibility, social and economic aspects, and vulnerability to environmental hazards. Multiple regression analysis was integrated with the GIS to identify significant variables that influence the spatial distribution of socialized housing. The comparison between the two regression models has shown that socialized housing is located in areas with inappropriate land use and poor accessibility to transportation facilities and built urban resources. Moreover, both regression models have proven the statistical significance of the vulnerability of socialized housing to environmental hazards. The finding explains how the current housing policies do not address the country's housing crisis, especially for the marginalized and low-income households. Thus, the findings provide implications for urban planners and local decision-makers in reforming the current policy interventions.

The domain name should be registered and used with the minimum length in consideration of the user's web accessibility and convenience. In addition, it is necessary to increase the status and authority of the library by allowing the type, region, and characteristics of the library to be known only by the domain name, and to consider the convenience of users. In this study, the situation of the state designated second-stage public domain and the second-stage public domain of educational institutions of similar character and size to the library are analyzed, and problems with the domain of libraries that do not have the second-stage domain are identified. Finally, second-stage public domains of national library (nl), public library (pl), and small library (sl) are proposed for each type of library, and the university library (lib. university domain) and school library (lib. School domain) proposed to use as the second-stage domains of the educational institution. The purpose is to allow users to intuitively know that these domains are libraries, to identify the type of library, and to know the characteristics and regions of the library. To this end, a joint effort by the academic community, the library community, and the Library Information Policy Committee is needed.
