In this study, we reviewed access transportation, operating companies, and airport infrastructure to revitalize Cheongju International Airport. Regarding access transportation infrastructure, it is necessary to promote a railway network connecting the metropolitan inland line and the central inland region. In addition, active administrative support from local governments is required to ensure smooth progress in railway and highway infrastructure linkage projects, such as the Osong Connecting Line and Chungbuk Line, high-speed rail network promotion, and expansion of the Chungbuk Eastern Axis Expressway and Central Expressway. Regarding operator access infrastructure, continuous efforts are required to add and attract airlines based at Cheongju International Airport. Regarding airport infrastructure, the Cheongju International Airport runway needs complete resurfacing due to its deterioration. Domestic passenger capacity has exceeded 6.5%, and considering the increase in import and export of high value-added goods in the North Chungcheong region, it is necessary to build and expand passenger terminals and cargo terminals. Cheongju International Airport's runway does not have enough runway length to operate large and ultra-large aircraft, so if it is extended from the existing 2,744m to 456m to 3,200m, several benefits can be expected in terms of revitalizing Cheongju Airport, such as route expansion.

Korea's port infrastructure is rapidly aging, with old port facilities with more than 30 years of public life expected to surge from about 23% in 2019 to 47% in 2029. Traditional, aging ports lose competitiveness in logistics processing, reducing development around the port and increasing human casualties due to the human resource-based maintenance of the facilities. Therefore, it is necessary to solve this problem by establishing systematic management technology based on a digital twin. This research aimed to present the specific implementation steps of a digital twin reflecting smart port technology through cases of port infrastructure disasters, aging status, and smart ports. The study analyzed the port infrastructure linkage system and created and mapped scenarios essential for digital twin implementation. Three-dimensional (3D) modeling and simulation data for disaster and aging management among existing port infrastructure systems were collected. A digital twin port was implemented with 3D modeling. It implements a port digital twin simulation that links data such as sensing data and image data acquired from the port infrastructure in real time. Implementing a digital twin port for port infrastructure disasters and aging management can secure predictive port infrastructure management and disaster safety

This study purposed to examine elderly welfare facilities by type, to analyze their local variations, and ultimately to contribute to the expansion of elderly welfare infrastructure. The results are expected to help inspect elderly welfare infrastructure for providing the aged with social services before the execution of 'the insurance for elderly long term care' and establish welfare facilities by area in the future. For these purposes, we used the national data "The Current State of Elderly Welfare Facilities in 2007" produced by the Ministry of Health and Welfare. We digitized elderly welfare facilities in 163 cities and counties by type and analyzed them by area. We also examined the differences in the local distribution of representative elderly welfare facilities such as elderly welfare centers, home based facilities (home helper centers), asylums for the aged and elderly care facilities in 16 cities and provinces. Furthermore, we analyzed differences and problems in their local distribution urban areas, mixed areas of urban and rural communities, and rural areas. In addition, we studied the current state of institutionalized care and home based care, which are two major directions of current elderly welfare policies, based on the local distribution of facilities and analyzed differences in the trends according to area. According to these results, the urban had more home based care facilities than the rural. However, the rural had more institutionalized care facilities than urban. Also, each local self-governing body showed unique characteristics. Therefore, these results suggest that we need to establish elderly welfare policies based on the distribution of facility types by area.

This study was conducted to pave the way for the development and operation of education and training programs to nurture skilled North Korean construction workers. Such programs would help to meet the expanded demand for setting up infrastructure, which is the backbone of the two Koreas' economic cooperation and mutual development. To achieve this initiative, the targets and scopes of education and training were determined by classifying business types for education and training purposes by construction sector. Furthermore, each education and training course and their allocated time frames were analyzed. Issues related to inter-Korean economic cooperation in the border area were also analyzed to determine regional characteristics. Education and training programs were thus classified into three types of infrastructure units: society, industry, and life infrastructure units. Social infrastructure units are the common demand of the whole border area, including construction of roads, railways, and harbors, as well as inspection and maintenance. Industrial infrastructure units are programs for industrial facilities centering on the designated special economic zone in the western part of the border area. Life infrastructure units are programs for infrastructure facilities such as large, complex facilities and residential facilities for the eastern tourist belt side.

This study is to find appropriate plant for infiltration swale (which is natural LID infrastructure) and suggest basic research database for building infrastructure of LID facilities. Through the research inside, it first selects the plant strong to flooding and salt tolerance. Also, the research built infiltration swale along the road, planted those strong plants and monitored how well those plants adapted into the environment. Particularly, it showered 72mm/hr-speed artificial shower, also with natural shower, given that plants were vulnerable to flood because of influx of the rain. As a result of field applicability monitoring, Pennisetum alopecuroides and Equisetum hyemale (which degrade the pollutant well and adapt into rainy environment) are planting individually, or Juncus effusus var. decipiens, Liriope platyphylla, Miscanthus sinensis Andersson, Euonymus japonica (which are strong to rainy environment) and Pennisetum alopecuroides and Equisetum hyemale are mixed planting. The research should have monitored the plant for more than one year to study them, but the research only lasted five months. Therefore, it is hard to generalize. After all, through the long term research, it should pursue study more on appropriate plant materials and database that can be the reference for infrastructure establishment and maintenance.

According to the change of the life environment and economic growth, the more highly a city has developed, the more concentrated is the urban function. That is, a city is required for adding more infrastructure. But, both limited land resources and financial problems made it impossible to add infrastructure. So, the necessity of multi-dimensional planning of urban infrastructure was recognized. Especially, in the urban residential area, a mixed-use of the playground of a school and the empty space of a park is desired to serve the issue of insufficient parking spaces. Schools and parks are closely connected to the center of a town, and playing a central role for the town life. For this reason, they are highly demanded in urban residential areas and also expected to be effective. However, we need to consider not only parking convenience but also the safety of users in design process, because people using parks and schools include young students and the elderly. In this study, we mainly examined physical characteristics and the utilization of schools and parks with parking facilities in urban residential areas. Then, we analyzed cases through comparing and evaluating in terms of convenience and safety. and weighed up advantages and disadvantages of each through the comparison of the schools and the parks having parking facilities. The results of this study are expected to provide fundamental references for preparing design standards for such facilities.
