While the conditions for using libraries in South Korea are improving in terms of the concept of a 15-min city, such as the expansion of public library functions and an increase in the number of libraries, the number of users per library is declining. This phenomenon represents the necessity of advancing the understanding of library use behavior from the policy aspects of facility planning, maintenance, and management. Hence, this study analyzes the effect of library services and distance on choices regarding library use and predicted changes in library use behavior through a choice experiment and a discrete choice model. The results reveal that library services, distance, and library-use status influenced library users' and non-users' decisions regarding library use. Through predictions of library use behavior, administrative districts that provide relatively low utility are identified, and the number of library users is estimated. Considering the impact of the interaction between library services and spatial patterns on potential users, it is possible to predict different library use patterns that can help make policy decisions regarding facility planning and management. • Preferences for libraries that apply the concept of a 15-minute city are analyzed. • Potential users' choice behavior of library is economically modeled and explored. • We divided the regular library user into single, transfer, and multiple user. • Library services and spatial patterns influence decision-making on library use. • Demand is estimated considering the differences across districts in the utility provided by libraries.

As a countermeasure to the greenhouse gas problem, the world is focusing on alternative fuel vehicles (AFVs). The most prominent alternatives are battery electric vehicles (BEV) and fuel cell electric vehicles (FCEVs). This study examines FCEVs, especially considering hydrogen refueling stations to fill the gap in the research. Many studies suggest the important impact that infrastructure has on the diffusion of AFVs, but they do not provide quantitative preferences for the design of hydrogen refueling stations. This study analyzes and presents a consumer preference structure for hydrogen refueling stations, considering the production method, distance, probability of failure to refuel, number of dispensers, and fuel costs as core attributes. For the analysis, stated preference data are applied to choice experiments, and mixed logit is used for the estimation. Results indicate that the supply stability of hydrogen refueling stations is the second most important attribute following fuel price. Consumers are willing to pay more for green hydrogen compared to gray hydrogen, which is hydrogen produced by fossil fuels. Driver fuel type and perception of hydrogen energy influence structure preference. Our results suggest a specific design for hydrogen refueling stations based on the characteristics of user groups.

Recent increases in fine and ultrafine dust in South Korea have led to sharp increases in the sale of air purifiers, and that trend is expected to continue. As the sale of air purifiers increases, the energy that is consumed by air purifiers also increases. Therefore, improving the energy efficiency of air purifiers is an important part of improving the overall energy efficiency of society. We studied how different incentive policies affect consumer behavior because encouraging people to buy energy efficient air purifiers is important. We first investigated consumer preferences regarding air purifiers. Stated preference data were gathered from a choice experiment and a mixed logit model was used for the analysis. The results show that the most preferred attribute was price, followed by an eco-label. Based on that result, we conducted a scenario analysis to examine the economic and environmental effects of an incentive policy and eco-labeling. The monetary incentive policy increased the market share for air purifiers with a first-grade energy efficiency rating to 2.2%. The annual electricity use reduction was 5.9 GWh, with a CO2 emission reduction of 2520 tons and a policy monetary benefit of KRW 441,340,922 when we converted the effect of that market share change into economic and environmental terms. Eco-labeling also brought considerable change in the market share. These results provide a reference for implementing policies to encourage consumers to purchase energy efficient air purifiers.
