As a way to solve the side effects of urban development, a smart city with information and communication technology converges in the city is being built. For this, a smart city platform should support the development and integration of smart city services. Therefore, the underlying technology and the functional and non-functional requirements that the smart platform must support were analyzed. As a result of this, we classified the Internet of Things, cloud computing, big data and cyber-physical systems into four categories as the underlying technologies supported by the smart city platform, and derived the functional and non-functional requirements that can be implemented and the reference model of the smart city platform. The reference model of the smart city platform is used for decision-making on investment in infrastructure technology and the development scope of services according to functional or non-functional requirements to solve specific city problems for city managers. It provides platform developers with guidelines to identify and determine the functional and non-functional requirements and implementation technologies of software platforms for building smart cities.

This study set up the estimates of leakage management efficiency evaluation and leakage management goal that could be used in local water distribution networks efficiency business and modernization business. The data were analyzed using data envelopment analysis and multiple regression analysis. To this end, with leakage management input indices concerning leakage reduction activities (e.g., aged pipe replacement, water meter replacement, leakage restoration, and leakage detection) and leakage management calculation indices (e.g., the increase of revenue water ratio and the reduction of leakage ratio), the data on 22 K-water consignment local water supply systems were analyzed for the years from 2004 through 2018. Using the results of efficiency analysis by data envelopment analysis, the other DMUs (Decision Making Unit) benchmarked the DMU with the highest efficiency to maximize the leakage management efficiency for all DMUs. Through this, leakage management goal estimates were drawn with the input indices of four leakage reduction activities and calculation indices of the increase of revenue water ratio and the reduction of leakage ratio by multiple regression analysis for each group based on the revenue water ratio and leakage ratio. The correlation coefficients of the leakage management goal estimate for the criteria for the revenue water ratio amounted to 0.553 and 0.771. The correlation coefficients of the leakage management goal estimate for the criteria for leakage ratio were 0.397 and 0.865. Accordingly, we estimated the quantity and priority of four leakage reduction activities for the target leakage ratio and revenue water ratio.

Recently, the number of consumers using digital online distribution platforms is increasing. This caused the rapid growth of the e-commerce market and increased delivery volume in urban areas. The logistics system, designed ar006Fund the city center to handle the delivery volume, operates a delivery system from the outskirts of the city to the urban area using cargo trucks. This maintains an ecosystem of high-cost and inefficient structures that increase social costs such as road traffic congestion and environmental problems. To solve this problem, research is being conducted worldwide to establish a high-efficiency urban joint logistics system using urban railway facilities and underground space infrastructure existing in existing cities. The joint logistics system begins with linking unmanned delivery automation services that link terminal delivery such as cargo classification and stacking, infrastructure construction that performs cargo transfer function by separating from passengers such as using cargo platform. To this end, it is necessary to apply the device to the vertical and horizontal transportation machine supporting the vertical transfer in the flat space of the joint logistics terminal, which is the base technology for transporting cargo using the transfer robot to the destination designated as a freight-only urban railway vehicle. Therefore, this paper aims to derive holistic viewpoints needs for design requirements for vertical and vertical transportation machines and freight transportation standard containers, which are underground railway logistics transport devices to be constructed by urban logistics ecosystem changes.

The purpose of this study was to compare and analyze characteristics of Gangwon Innovation City and Wonju Company Town. Both were created with similar purpose, place, time, and scale. However, they were created with different approaches: relocating public institutions and attracting private institutions. For research data, population microdata provided by the National Statistical Office were used. As a result of the analysis, the Gangwon Innovation City and the Wonju Company Town greatly influenced the population growth of Wonju and the movement of the population within Wonju. The influx of population into the study area brought positive changes in both demographic structure and population indices. Excluding relocation to Wonju-si, Innovation Cities and Company Town accounted for more than 50% of those who migrated from the metropolitan area (Seoul, Gyeonggi and Incheon). The supply of apartment houses (apartments) in the Innovation City and the Company Town stimulated the transfer from the inside of Wonju to this area. For households that moved to Gangwon Innovation City and Wonju Company Town, the most common reasons for moving in were housing, occupation, and family.

We identified the mediating role of interpersonal issues in the relationship between adult attachment type and emotional expression ambivalence. The subjects of the study were 327 emotional workers who lived in five cities. As the scale, ECR-R, AEQ-K, and IIP were used. Sobel verification was performed after multiple regression analysis. The results show that the interpersonal problem partially mediates between the attachment and emotional expression ambivalence. This suggests that the characteristics of interpersonal relationships affect emotional emotions in forming close attachment relationships of emotional workers. Subsequent research will expand the scope of research by supplementing the shortcomings of existing research.
