With the rapid development of information and communication technology, online dissemination increases rapidly. So, It becomes more important to protect information. Recently the authentication system using public key infrastructure (PKI) is being utilized as an information protection infrastructure for electronic business transactions. And the smartcard system makes the most use of such an infrastructure. But because the certification based on the current PKI provides oかy basic user certification information, the use has to be limited in various application services that need the identification and authorization information as well as face-to-face information of the user. In order to protect a system from various kinds backings and related treats, we have proposed angular and private key multiplexing for prevention of smartcard forgery and alteration based on a photopolymer cryptosystem. When smartcard becomes prone to forgery and alteration, we should be able to verify it. Also, our parer proposes a new authentication system using multi authentication based on PKI. The smartcard has an excellent advantage in security and moving.

The donation collection system to secure infrastructure and land necessary for public development projects has been actively applied as an effective means of realizing public interest and the concept of recovering development profits, and has contributed greatly to society in public difficult financial conditions. However, due to the ambiguous legal standards and lack of legal grounds for the operation of the donation collection system, it has been arbitrarily used for administrative convenience in the form of granting a donation collection assistant to install infrastructure. In addition, infrastructure is a facility that is constructed and donated within development profits to obtain licenses, and is promoted to minimize construction costs to improve profitability, posing a risk of poor infrastructure planning, design, and construction, resulting in increased safety and maintenance costs for citizens. Continuous system and legal improvement are needed to improve the excellence, convenience, and safety of facilities that citizens will use for half a century through the improvement of the donation system.

Forward secrecy in an e-mail system means that the compromising of the long-term secret keys of the mail users and mail servers does not affect the confidentiality of the previous e-mail messages. Previous forward-secure e-mail protocols used the certified public keys of the users and thus needed PKI(Public Key Infrastructure). In this paper, we propose a password-based authenticated e-mail protocol providing forward secrecy. The proposed protocol does not require certified public keys and is sufficiently efficient to be executed on resource-restricted mobile devices.

We establish an efficient strategy for construction and operation of data consolidation center for multi-organization in public sector. First, we introduce important concepts on data consolidation center in public sector, and draw some success factors by analyzing several foreign and domestic cases. Second, we construct all the possible logical operational models of the center and investigate the properties and feasibility of the models. Third, we suggest a virtual operational environment for the two representative models selected by feasibility criteria among the possible logical models, and compare the two models in terms of operational cost. We also utilize AHP methodology to evaluate qualitative opinions on the two models from several experts in public information systems. As a result, we find the best alternative is the case in which all infrastructure and facilities for the center are provided by government, and common essential IT operations are integrated, associated data are consolidated and the whole operational work are outsourced to specialized IT operations service providers.

Korean government implemented the Build-Transfer-Lease (BTL) mechanism since 2005 as one of the privatization methods to procure the social infrastructure with private investment. The mechanism was originally prepared 10 provide such public properties as education facilities, child-care facilities, old generation recuperation facilities, medical welfare facilities, military personnel's apartments, environment facilities, and lease apartments. Since 2005, a total of 13.5 trillion won-valued private fund has been directed to the public educational facilities, which occupies 58% of the total private investment in the facilities of the seven categories. However, many officials in the local public entities have anticipated that the local entities need to be restructured or downsized because of the privatization in stead of providing the educational facilities by governmental finance. The main objective of this study is to identify the appropriate technocrat organization structures to manage the privatization procedures.

Purpose: The role and facilities of public health centers responsible for local health are becoming increasingly important due to recurring infectious diseases such as COVID-19. With sudden outbreaks of infectious diseases, the infrastructure of public health center facilities like screening clinics are constructed varies depending on local conditions. resulting in discrepancies between intended usage and actual usage. Establishing guidelines for infectious disease response facilities that can be efficiently used within local communities is necessary. Methods: Field surveys are conducted at 6 public health centers to gather insights into the essential rooms, circulation patterns, and key considerations for space planning in screening clinics. Results: Ten design considerations emerge from the data, including spatial requirements, circulation guidelines, and considerations for accommodating diverse user needs and local conditions. Implications: Further research is needed to translate these guidelines into prototypes of temporary facilities.

This study considers that the establishment of a public library within multi-use complex is one of the most effective ways to expand infrastructure of public libraries in Korea. A survey on the complexation rates of public libraries in Seoul was made through on-the-spot visits and telephone interviews. It turned out that out of all 112 public libraries in Seoul, 55 of them are in multi complex buildings. In order to efficiently establish public libraries to multi-use complex, absolute consideration on the size, location, and space should be made. Moreover, if necessary, additional complexation with commercial facilities, schools, and local government buildings should be made.

The recent Middle East respiratory syndrome coronavirus (MERS-CoV) outbreak has originated from a failure in the national quarantine system in the Republic of Korea as most basic role of protecting the safety and lives of its citizens. Furthermore, a number of the Korean healthcare system's weaknesses seem to have been completely exposed. The MERS-CoV outbreak can be considered a typical public health crisis in that the public was not only greatly terrorized by the actual fear of the disease, but also experienced a great impact to their daily lives, all in a short period of time. Preparedness for and an appropriate response to a public health crisis require comprehensive systematic public healthcare measures to address risks comprehensively with an all-hazards approach. Consequently, discussion regarding establishment of post-MERS-CoV improvement measures must focus on the total reform of the national quarantine system and strengthening of the public health infrastructure. In addition, the Korea Centers for Disease Control and Prevention must implement specific strategies of action including taking on the role of "control tower" in a public health emergency, training of Field Epidemic Intelligence Service officers, establishment of collaborative governance between central and local governments for infection prevention and control, strengthening the roles and capabilities of community-based public hospitals, and development of nationwide crisis communication methods.

This Paper examines theoretical terrains and design strategies of landscape urbanism which is an emerging hybrid field at the intersection of architecture, landscape architecture, and urbanism. Landscape urbanism offers alternative approaches for theory, education, and practice in contemporary landscape architecture. It views the emergent urban complex sites-post-industrial sites, landfill, brownfield, urban void, etc., not as a weakness, but as a strength. Landscape urbanism poses an understanding of landscape as an element of urban infrastructure. In this sense, the landscape is seen in the context of contemporary urban development and public works. As a complex amalgam, landscape urbanism is more than a design style it is an ethos, an attitude, a way of thinking and acting. We can chart the main characteristics of landscape urbanism such as horizontality and surface, infrastructure, process, technique, and ecology. Multilayered examples of landscape urbanism can be seen in several experimental practices such as worts of Rem Koolhaas, MVRDV, Adriaan Geuze/West 8, James Comer, etc. It is possible to summarize the productive strategies for landscape urbanism as follows : thickening, folding, new materials, nonprogrammed use, impermanence, and movement.
