Private archives are an important indicator of understanding a society that contains various memories, the lives and experiences of members, daily lives, morality, and values. Recently, as diversity has emerged as an important value in Korean society, a number of individuals and communities have been appeared based on different bases and purposes, and the contents, types, and categories of private archives produced from their voluntary activities have also diversified. These private organizations and communities are potential targets for producing and holding private archives, but most of them do not have the minimum infrastructure or system for management of archives, and the foundation for management of archives is weak only to be supported with the voluntary will and activities of the private sector. Therefore, there is a need for a plan to support activities to manage archives suitable for each organization's level while respecting the unique characteristics and methods of the private sector within the national management system of archives. In addition, since it is difficult to solve all issues related to management of archives in the private sector with only a small number of process topics, a cooperative system should be established to sustain activities to manage archives on its own through networks between private sectors. In this study, we intend to propose a 'private archives information network platform (hereinafter referred to as a platform)' as a way to establish a communication and network foundation between private sectors and share resources with each other. Based on the results of analysis of cases of building network between private sectors and expected user requirements, we would like to establish a vision and target model of the platform and discuss ways to continuously operate the platform.

IETF에서 IPSec(Internet Protocol Security)[1]의 구조를 발표한 이래 IPSec을 이용한 많은 VPN(Virtual PrivateNetwork)[2][3]이 구축되어 왔다. 이렇게 구축된 VPN에서 사용되는 CG(CryptoGate) 혹은 SG(Security Gateway)는 각각의 망에서 게이트 역할을 한다. 하지만 이런 기존의 CG나 SG는 IPSec의 정책을 사용자가 선택하는 것이 아닌 망 관리자가 일방적으로 서비스하도록 설계되어있다. 이러한 점은 사용자가 자신의 데이터를 평가하여 자율적으로 그에 맞는 서비스를 이용하는 것이 아니므로 사용자가 사용하는 것을 꺼릴 수도 있다. 또한 게이트웨이에 자신의 키를 백업할 수 있도록 하여서 사용자가 다시 이 망에 접근할 경우 다시 키 협상을 하는 것이 아닌 백업해둔 키를 가지고 연결할 수 있도록 하였다. 본 논문은 VPN에서 이러한 점을 고려하여 CG를 설계함으로써 VPN 사용의 확장성을 해결한다.

As the social distance has been strengthened by the COVID-19 Pandemics, telecommuting has spread, and government agencies have also begun telecommuting since March and are still maintaining a certain level. The Government's remote work service, Government Virtual Private Network (GVPN), which is essential to telecommuting of government agencies, is expected to cause a number of problems with the rapid increase in users in a short period of time. Therefore, a survey and statistical analysis were conducted to analyze the impact of the quality factors of GVPN on the users' satisfaction to the public officials of the government departments who are directly using it, and based on these results, we intend to derive the implications necessary for the improvement of GVPN for remote work in preparation for the full-fledged spread of the non-contact era.

In a network environment, when a user requests a server's service, he/she must pass an examination of user authentication. Through this process, the server can determine if the user can use the provided services and the exact access rights of this user in these services. In these authentication schemes, the security of private information became an important issue. For this reason, many suggestions have been made in order to protect the privacy of users and smart cards have been widely used for authentication systems providing anonymity of users recently. An remote user authentication system using smart cards is a very practical solution to validate the eligibility of a user and provide secure communication. However, there are no studies in attribute-based authentication schemes using smart cards so far. In this paper, we propose a novel user authentication scheme using smart cards based on attributes. The major merits include : (1) the proposed scheme achieves the low-computation requirement for smart cards; (2) user only needs to register once and can use permitted various services according to attributes; (3) the proposed scheme guarantees perfect anonymity to remote server.

Smart Grid is a next generation of new power growth electrical grid which provide high quality of electrical service by using Information Technologies to increase intelligence and performance. By using Smart Grid system, it can support energy management such as increase quality of electrical power, decrease energy and decrease emissions. However, Smart Grid uses information of energy consumption and when Smart Grid collects information, it will create private information. In this thesis, it will address issues of security private information which caused by Smart Grid for administrative measure and efficiency of Smart Grid in domestic. Also, cryptographic module algorithm, latest security solutions and strong wireless security policy for network environment such as wireless communication Iinternet are require for Smart Grid perform successfully and protect national power network equipment from cyber-attack and can stop leakage of user's personal information. Finally, it is urgent to prepare protection measures of National industrial facilities and power grid which can prepare for a cyber terrorism and penetration attacks and build emergency countermeasure management team for Smart Grid are require for safe Smart Grid environment.

The changes of university entrance system which is affecting public library management and services, and current situation of private education market were analyzed for this study. It was revealed that we have several competitive forces that determine library service justification in Korean service environment(market) which has not experienced in the developed countries. The elements of private education may drive competition in the book reading service industry. Such elements effectuate serious problems and discourage library service marketing to the user. For a sustainable competitive advantage, English language collection and reading program model was developed for library marketing strategies(as applying leverage).

This study explores the feasibility of activating private health insurance in Korea. The rationale for expanding private supplementary health insurance can be found in many cases of health care reforms in the European countries. Private health insurance can not only relieve the financial distress of the government health insurance programs but also offer the medical institutions incentives to improve the quality of medical care. In Korea there is no supplementary health insurance that reimburses for various kinds of diseases based on a well designed fee schedule. Recently, the cancer insurance is the best seller in the health related insurance market. As observed in the U. S. case, the cancer insurance which pays the predetermined amount (indemnity coverage) regardless of the medical charges incurred to the patient is limited in its coverage for the insured. To provide better protection against catastrophic diseases, the government should give insurance companies incentives to develop health insurance products that cover multiple diseases rather than a single disease. Consumers can hardly understand and compare complex insurance products. To resolve the information asymmetries, the government should publish a consumer report that compare various health insurance products in a user friendly way. In the long run, insurance companies will plan to sell health insurance products that charge risk related premium only when insurers accumulate the underwriting know-hows, the government shares data on various health statistics including claims and demographics, and risk pool for high risk patients is well established and subsidized by the government.

Recently, Korea government make an effort to make jobs through public information disclosure and a public-private partnerships. In this regard, the MOLIT (Ministry of Land, Infrastructure and Transport) is pushing the V-World Business. The V-World is the public platform for the government to disclose spatial and adminstration information. However, the V-World is still not been able to fulfill the role of a public platform, private partnerships window, Warehouse jobs. So, the molit is promoting the V-World advanced project, creating a long-term plan. This study performed a user satisfaction survey and analysis, this result are used as a basis data of the efficient execution of the V-World advanced project and creating long-term planning. Also, we suggested V-World Service Improvement, Open API Service Improvement, future service direction. This study improve the current the V-World, will be utilized as basic data of improving utilization of the use.

Due to the advance of computer and communication technology, intrusions or crimes using a computer have been increased rapidly while tremendous information has been provided to users conveniently Specially, for the security of a database which stores important information such as the private information of a customer or the secret information of a company, several basic suity methods of a database management system itself or conventional misuse detection methods have been used. However, a problem caused by abusing the authority of an internal user such as the drain of secret information is more serious than the breakdown of a system by an external intruder. Therefore, in order to maintain the sorority of a database effectively, an anomaly defection technique is necessary. This paper proposes a method that generates the normal behavior profile of a user from the database log of the user based on an association mining method. For this purpose, the Information of a database log is structured by a semantically organized pattern tree. Consequently, an online transaction of a user is compared with the profile of the user, so that any anomaly can be effectively detected.
