우리나라의 공공도서관 수는 최초의 '도서관법'이 제정된 이후 지난 40년간 큰 폭으로 증가하였다. 그러나 이러한 증가에도 불구하고 공공도서관 시설은 선진국과 비교해 보면 여전히 많은 차이가 나고 또 절대적으로 크게 부족하다. 이러한 결과는 지금까지 추진해 왔던 대규모 형태의 공공도서관 건립 방식이 도서관을 확충하는데 효율적이지 못하다는 것을 증명한다. 따라서 우리나라의 공공도서관을 짧은 시간 내에 획기적으로 확충하기 위해서는 영국의 경우처럼 작은 공공도서관을 건립하는 방법을 채택하여야 한다. 즉, 몇 개의 큰 공공도서관을 건립하는 방식을 탈피하여 큰 도서관을 건립할 비용을 쪼개어 여러 개의 작은 도서관을 건립 운영하도록 한다.

The objective of the study is to discuss the public value which inevitably required in the relation between city and transportation infrastructure and to suggest a public space at a transfer center which is a new type of transportation infrastructure. There has been little discourse on the public value of existing transportation infrastructure in the field of landscape architecture. Through this study. re-think of urban infrastructure from landscape architectural point of view will be examined. Through this study, three main considerations will be reflected in designing a transfer center, First, in a broad context, possibility of landscape architectural access toward transportation infrastructure should be considered. Secondly, unique characteristics of the transfer center system will be reflected on design process. Lastly, by analysing the site context of Dobongsan station P&R, design issues will be emerged. Transportation infrastructure is a field of urban life where people gather, exchange and do diverse activities. Design of transfer center through landscape architectural approach will be a meaningful reaction to the needs of public space in the urban infrastructures.

The subject village of our study has numerous tourist attractions around it, and possesses various Confucian cultural heritages. The purpose of this study is to investigate public space improvements of a village possessing abundant historical and cultural heritages that has turned into a experience-tour village. As for the research method, cultural and social characteristics of the village were identified. In addition, infrastructures were classified by livelihood based infrastructure, tour based infrastructure, and agriculture based infrastructure in order to analyze individual public space improvement cases. As a result, it was found that public space improvements of the village improved the educational facilities and tour resources using historical resources. In addition, it was found that public spaces for residents to get along with tourists(who are willing to experience the village) were created.

Purpose - This study examines the relationship between public-private partnerships and the performance of ports based on three factors: the quality of the port infrastructure, container throughput, and logistic performance in three Latin American countries, Mexico, Panama, and Brazil, for the period of 1994-2017. Design/methodology - The selected countries are top ranked in terms of container throughput in Latin America. The methodology employs secondary data from the World Bank (Quality of Port Infrastructure, Logistics Performance Index, and Private Participation in infrastructure database). Findings - Overall, the results revealed that the private investment of these countries varies significantly over the past couple decades. Panama, with the least public-private investment over the study period, performs better than Mexico and Brazil with regards to port quality infrastructure and container throughput. For ports in the selected countries to keep up with global competition, there is a need to enhance efficiency. Originality/value - Compared with ports in Asia, Latin American ports are lagging behind with respect to container throughput and efficiency. This study suggests greater collaboration from the private sector, academia, and other organizations, as well as a review of the regulatory framework to ensure better transparency and project allocation. Throwing more light on the public-private investment environment of Mexico, Brazil, and Panama, this study offers policy makers and regulators insightful information on port infrastructure.

Public infrastructure is crucial to promote and sustain a sustainable economic growth and a health community. A large amount of capital investment is generally required in infrastructure projects that motivate the involvement of the private sector in the delivery process. Various relationship-based procurement methods have been attempted to maximize value-for-money. In this paper, the problems and challenges that relationship-based procurement methods have been facing are explored. A particular focus is placed on the challenges for the public-private partnership (PPP) model. Possible strategies for adapting the PPP models in the post-Global Financial Crisis era are proposed and discussed. In addition, the challenges facing alliancing, which is one of the other important relationship-based procurement methods, are also examined. Views on infrastructure procurement in the future were sought from industry professionals via interviews and are reported in this paper as well.

정보보호의 중요성이 인식되면서 암호 기술의 사용이 증가하고 있다. 특히, 공개키 암호 기술은 대칭키 암호기술에 비해 키의 관리가 용이하고, 디지털 서명을 쉽게 구현할 수 있다는 장점을 가지고 있어서 그 사용이 증가하고 있다. 현재 공개키 암호 기술을 효율적이고 안전하게 사용하기 위한 공개키 기반 구조가 구축되어 운영되고 있다. 공개키 기반 구조에서는 사용자가 인증기관에 등록하여 개인키와 공개키 쌍을 생성하고, 인증기관은 생성된 공개키에 대한 인증서를 발행한다. 이러한 인증서를 이용하여 사용자간에 키 설립을 수행하고 암호화통신을 할 수 있게 된다. 그러나 공개키 기반 구조에서 설립된 세션키에 대한 관리 기능은 제공하고 있지 않다. 본 논문에서는 무선 인증 및 키 설립시 설립된 세션키에 대한 키 복구를 지원하는 인증서 발행 프로토콜을 제안한다.

The local public organizations, to secure the Confidentiality, Integrity, Authentication and Non-Repudiation of cyber administrative environment is giving it a try to consolidate the official documents among them by standardizing all the documents into XML formats together with the establishment of the GPKI(Government Public Key Infrastructure). The Authentication System based on the PKI(Public Key Infrastructure) used by the GPKI, however, provides only the simple User Authentication and thus it results in the difficulty in managing the position, task, role information of various users required under the applied task environment of public organizations. It also has a limitation of not supporting the detailed access control with respect to the XML-based public documents.In order to solve these issues, this study has analyzed the security problems of Authentication and access control system used by the public organizations and has drawn the means of troubleshoot based on the analysis results through the scenario and most importantly it suggests the access control model applied with PMI and SAML and XACML to solve the located problem.

Public-private partnerships (PPP) projects are becoming popular in both developed and developing countries due to their ability to access new financing sources and transfer certain project risks to the private sector. PPP has been an active research area where the concept of Critical Success Factors (CSF) is often discussed by researchers. This study aims to identify the CSFs for various PPP infrastructure projects that have been explored in previous CSF studies. This article reviewed the literature about CSF in PPP projects from the years 2002 to 2021, compared the findings of studies regarding the identified CSFs, and consolidated the CSFs that can be applied to various PPP infrastructure projects. The results showed that dominant research focused on general infrastructure, where CSFs can be applied to all infrastructure sectors rather than any specific sector. The most identified CSFs from the study are favorable and efficient legal frameworks, appropriate risk allocation and sharing, a robust and reliable private consortium, a competitive and transparent procurement process, and political support and stability. The findings from the study can provide an overview of CSFs that are relevant to specific PPP infrastructure sectors like building infrastructure, transportation, water, etc. as well as for general infrastructure. In addition, the results can also be used for further empirical analysis.
