All public libraries are local public goods and cultural infrastructures whose ideological pillars are publicly operated, free, and open to all. This identity is justified when the public library provides various knowledge information, various programs, and community space to local residents within the service area, and ultimately contributes to the cultural development of the nation and society. To this end, the country and local governments must expand the number of individuals that meet legal standards, deploy competent professionals, and provide facilities and spaces that are easy to access and use. However, if there is a gap in infrastructure and services between regional public libraries, it causes inequality in access and use of residents, which inevitably leads to information gap and cultural welfare gap. Therefore, this study was analyzed the relative gap using the location quotient, key infrastructure indicators and service indicators of public libraries of regional government in Korea and basic local government in the Chungnam region from the viewpoint that the balanced development and capacity building of public libraries must precede the establishment of a public library in Chungnam region as a life-friendly knowledge information service institution, culture enjoyment and lifelong learning space. Based on the results, a method to resolve the gap was suggested by dividing the elements of gaps in public libraries into accessibility, core infrastructure, and services, focusing on vulnerable cities and counties in the Chungnam region.

OCSP (Online Certificate Status Protocol) server which checks the certificate status provides the real time status verification in the PKI (Public Key Infrastructure) system which is the essential system of certificate. However, OCSP server need the message authentication with the server and client, so it has some shortcomings that has slow response time for the demands of many clients concurrently and has complexity of the mathematical process in the public encryption system. In this research, simulation model of the certificate status vertification server is constructed of the DEVS (Discrete EVent system Specification) formalism. This sever model is constructed to practice the authentication with hash function when certificate is checked. Simulation results shows the results of increase of the certificate status verification speed and decrease of the response time to the client.

There have been enormous efforts to develop an innovative public transport bus service for enhancing its operational efficiency based on Automated Vehicle(AV). However, since the vehicle operating environment in the public transport system varies with the purpose and method of mobility service, it is necessary to preferentially evaluate the current roadworthiness for an effective way to introduce the AV. Therefore, this study classified and redefined AV-based mobility service based on literature reviews. This research conducted the roadworthiness test for checking the feasibilities of the AV-based mobility services. Furthermore, we suggested some deployment strategies of the AV-based mobility service considering the Level-Of-Service (LOS) of road infrastructure based on the results of roadworthiness tests. The proposed direction would have a great potential to introduce the AV-based public transport system in the near future.

Regardless of area, public libraries should establish its status as the knowledge and information service center, cultural enjoyment and lifelong learning space in close contact with everyday life. To do this, it is necessary to survey the citizen's perception of the public library. In this study, researchers investigated and analyzed the perception of Daegu citizens including the weight and importance of public libraries, library use status and reasons for non-use, reading program participation and reasons for non-participation, and regions that require new library facilities. Based on these results, researchers suggested the measures to strengthen the infrastructure of public library and to increase its use in conjunction with other relevant data, that is, domestic and international researches, related laws, national reading survey, national cultural infrastructure overview, Daegu citizen survey, Daegu city brand perception survey, and the status of public libraries in national and Daegu Metropolitan City.

Public bicycles are a representative eco-friendly transportation means that can reduce carbon emissions and play an important role in first/last mile mobility and that can be linked to public transportation in the future MaaS era. In 2008, Changwon City started operating donor bicycles for the first time in Korea. However, as the infrastructure of public bicycles has expanded without a theoretical basis for over 10 years, operating costs are increasing due to a decrease in operational efficiency, which makes it difficult to quantitatively expand the service. In this study, a method for calculating the number of stands suitable for the use of public bicycles was presented, and an efficiency index was developed to evaluate the efficiency of public bicycle infrastructure. The method presented in this study was found by examining the relationship between numbers of rentals and returns of public bicycles and the number of bicycle holders. It is expected that the results can be used by other local governments.

India has accorded a high priority to road infrastructure development through Public-Private Partnership (PPP) and it has set a high target for investment inflows. Yet, it is widely held that road/highway infrastructure has not been developing at required pace and that the road infrastructure projects under PPP have been suffering from several hurdles and delays, thereby affecting project success/failure. This paper is an attempt to analyze the critical success/failure factors of road infrastructure projects under PPP in India. A questionnaire survey was conducted among a sample of the stakeholders of road infrastructure projects to identify the critical success/failure factors during all four major project stages using different approaches. Initially, the critical factors were identified through ranking based on the average/mean score. Later, the conventional RII score was used to identify the critical success/failure factors. Finally, the critical success/failure factors were also identified based on the stakeholder-wise ranking of the factors and their convergence. The assessment revealed that there was a greater convergence across the different methods and also that there was greater consensus among project stakeholder on the critical success/failure factors of road PPP projects.

Purpose - Multiple stakeholders-including politicians, investors, and the wider public-have questioned the value of investing in port infrastructure improvements and the contributions they can make to economic performance. Design/methodology - This paper presents an empirical study of 56 countries with seaports from the year 2006 to 2019 to determine how the quality of port infrastructure affects its contribution in terms of trade openness and economic growth. To this end, this study applies hierarchical multiple regression analysis with panel data to empirically examine the economic impact of port infrastructure quality on the relationship between trade openness and economic growth. After the 56 selected countries were categorized as developed or developing, a multi-group panel data analysis was conducted. Findings - The results of this study show that trade openness has a significant positive effect on the national economy. The findings also indicate that, although developing countries should expect greater economic growth after investing in port infrastructure, this relationship weakens as developing countries become richer. Originality/value - The findings of this study not only elucidate the relationship between trade openness and national economic growth, but they also emphasize the importance of trade openness and port infrastructure in national economic growth, particularly among developing countries.

This paper aims at analyzing the economic effect of the public financial expenditure on the national industrial complexes. Since public finance support is indirectly supplied to the national industrial complexes, the economic effect of the public financial expenditure on the national industrial complexes may be analyzed indirectly and circuitously In this contort, this paper uses 3 stage analysis method. In the first stage, the economic effect that the public financial expenditure influence the allotment, production and employment of companies residing in the national industrial complexes is analyzed by multiple regression analysis. In the second stage, the economic effect that the investment on the national industrial complexes influence the national and regional economies is analyzed by multiple regression analysis. In the third stage, the economic effect of the public financial expenditure on the national industrial complexes is analyzed through the compromising the results of the first and second stage. The main results of this paper are as follows. Firstly, public financial expenditure on the infrastructure of national industrial complexes leaded to positive growth of the allotment of companies residing in the national industrial complexes. Additionally, growth of the allotment of companies leaded to the positive effect on the production and employment of companies. And secondly, growth of the allotment of companies leaded to the positive effect on the gross regional domestic production. Finally, financial expenditure on the infrastructure of national industrial complexes leaded to positive effect on the national and regional economic growth through the compromising the results of the first and second stage.
