This study based on the 8-step strategy model for change management proposed by J. P. Kotter, tried to check the perception and experience about change management of the librarians at National Library of Korea. Also this study aimed to figure out the understanding of each 8-step strategy model. To this end, the concept and process of change management were presented through literature analysis, and survey was conducted targeting 58 librarians of the National Library of Korea. This study drews five results. First, the majority of librarians at National Library of Korea do not know about change management, and they do not have experience in using change management techniques. Second, the period required for the 8-step change management process is 5 years. Third, during the change management stage, librarians' awareness of the importance of stages 4 and 3 was high. Fourth, there is no difference in the librarians' perceptions of change management by gender, education, major, and tasks. Fifth, there is a significant difference in the age and service years of the librarian in the 3rd, 4th, and 7th stages of change management. Also there is a significant difference in the position of the librarian at the 1st and 3rd stage of change management, and between librarians' department and 1st stage of change management. The findings and results of this study can not only raise awareness of change management but also suggest organizational responses to change at individual or organizational level.

Recently, there are various employment-related homepages such as Jobkorea and World Job. However, since these websites have the one-to-one communication with corporate users and users, the amount of information that can be obtained from the viewpoint of users is limited. The proposed system improves this limitation, where a user creates a blog through member registration, uploads and creates a document to a blog, and a company official can perform an annotation function. This enables users to easily manage the desired documents, share information with other users, and affix them to the users who want to add to the company, so that the corporate users and users can communicate with each other. Thus, we believe that the proposed model can solve problems in the current job market and provide a new level of portfolio system for new media environment.

There are many investors in the stock market, and more and more people get interested in the stock investment. In order to avoid risks and make profit in the stock investment, we have to determine several aspects using various information. That is, we have to select profitable stocks and determine appropriate buying/selling prices and holding period. This paper proposes a data mining tool for the investors' decision support. The data mining tool makes stock investors apply machine learning techniques and generate stock price prediction model. Also it helps determine buying/selling prices and holding period. It supports individual investor's own decision making using past data. Using the proposed tool, users can manage stock data, generate their own stock price prediction models, and establish trading policy via investment simulation. Users can select technical indicators which they think affect future stock price. Then they can generate stock price prediction models using the indicators and test the models. They also perform investment simulation using proper models to find appropriate trading policy consisting of buying/selling prices and holding period. Using the proposed data mining tool, stock investors can expect more profit with the help of stock price prediction model and trading policy validated on past data, instead of with an emotional decision.

In this knowledge-based society of this age, librarianship takes a professional position and requires essential principles of ethics that has to be observed. Therefore, library associations and professional communities all over the world have released criteria and code of ethics to make their professional positions to keep. This research investigated and analyzed the codes of ethics for librarians in United States, Great Britain, Japan, and South Korea which are based on the mission of each library of each country. Based on these analysis and comparison, this research proposed more advanced codes of ethics for South Korea. The proposed model of codes of ethics consists of two parts: ethics for information and ethics for professional positions. The ethics for information contains six essential elements: equal access and services for information, denial of inspection, protection of privacy, neutralization of librarian, and security of intellectual freedom. The ethics for professional positions consists of 8 essential aspects: exclusion of personal benefit, continuous efforts for developing knowledge, keep the professional position, conflicts between professional task and organization, relationship with co-workers, ensure the conditions of rights and welfare for employees, cooperations among libraries, and contribution for creation of new culture.

With the development of information technology, fake news is becoming a serious social problem. Individual measures to manage the problem, such as fact-checking by the media, legal regulation, or technical solutions, have not been successful. The flood of fake news has undermined not only trust in the media but also the general credibility of social institutions, and is even threatening the foundations of democracy. This is why one cannot leave fake news unchecked, though it is certainly a difficult task to accomplish. The problem of fake news is not about simply judging its veracity, as no news is completely fake or unquestionably real and there is much uncertainty. Therefore, managing fake news does not mean removing them completely. Nor can the problem be left to individuals' capacity for rational judgment. Recurring fake news can easily disrupt individual decision making, which raises the need for socio-technical measures and multidisciplinary collaboration. In this study, we introduce a new public online platform for fake news management, which incorporates a multidimensional and multidisciplinary approach based on citizen science. Our proposed platform will fundamentally redesign the existing process for collecting and analyzing fake news and engaging with user reactions. People in various fields would be able to participate in and contribute to this platform by mobilizing their own expertise and capability.

One of the main chalenges in personal communication services (PCS) is to locate many mobile terminals that may move frequently from place to place. Such a system operation is called location management. Many network signaling traffic, and database queries are required to achieve such a task. Several strategies have been proposed to improve the efficiency of location management. These strategies use location register databases to store the current location on mobile terminals, and are vulnerable to failure of the location registers. In this paper, we propose a fault-tolerant pointer forwarding with distributed home location register (FT-RFDHLR) to tolerate the failure of location registers. The performance of the proposed method is evaluated by an analytical model, and is compared with thew pointer forwarding with the single home location register (PFSHLR), the pointer forwarding with distributed home location register (PFDHLR), Biaz's bypass forwarding strategy (BFS) and two-path forwarding strategy (TPFS).

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.

As Ransomware spreads, the target of the attack shifted from a single personal to organizations which lead attackers to be more intelligent and systematic. Thus, Ransomware's threats to domestic infrastructure, including the financial industry, have grown to a level that cannot be ignored. As a measure against these security issues, organizations use ISMS, which is an information protection management system. However, it is difficult for management to make decisions on the loss done by the security issues since amount of the damage done can not be calculated with just ISMS. In this paper, through FAIR-based loss measurement model based on scenario's to identify the extent of damage and calculate the reasonable damages which has been considered to be the problem of the ISMS, we identified losses and risks of Ransomeware on the financial industry and method to reduce the loss by applying the current ISMS and ISO 27001 control items rather than modifying the ISMS.

Convergence-based Smart Work in Korea started from 2010 with a purpose to improve work-life balance. Up to now the previous research on Smart Work has been studied in the context of the pre-adoption or the adoption stage, and shows some limitations not finding out the effort to manage change, the issues occurred in the process of adopting Smart Work, and the performance after adopting Smart Work. The period after adoption is when users continue to use ICT and intended objectives can be accomplished. Therefore, this study investigated the process that the organizations adopting Smart Work have overcome spatial and temporal constraints and the performance that they have achieved after adopting it. Though the framework integrating time-geography theory with technology acceptance stage, this research interviewed four managers of three organizations being responsible for adopting and operating Smart Work and provided its adopting process and performance of each organization.
