온라인 게임에는 해킹이나 악성 코드와 같은 다른 분야에서도 널리 알려진 위협뿐만 아니라 계정 도용이나 자동 사냥 프로그램 사용과 같은 온라인 게임에서만 볼 수 있는 위협들이 존재한다. 온라인 게임은 게임 유저의 다양한 활동을 데이터로 기록하기 때문에 이런 풍부한 데이터를 활용한 머신 러닝 기반의 탐지 기법을 적용하기 적합한 분야이다. 그럼에도 불구하고 다른 보안 분야에 비해 상대적으로 연구가 많이 되지 않고 있으며 대부분의 연구가 탐지 모델링 단계에 집중되어 있다. 본 논문에서는 머신 러닝에 기반한 온라인 게임 보안 시스템을 효과적으로 구축하기 위한 연동 구조와 실전 적용시 고려해야 할 점에 대해 소개한다.

Recent trends in sharing online video contents show that vlogging on everyday life can cause meaningful changes in viewers' perception of mediated characters and their own lifestyles. We explored that flourishing everyday life video contents online are intertwined with viewers' psychological engagement such as empathy and social presence, let alone self-enhancing motivations such as self-reflection and psychological empowerment. Survey analysis results suggest that between contents types of vlog (everyday life vs. in-depth information), watching in-depth information videos significantly affected viewers' psychological engagement and self-enhancing motivations. Compared to celebrity's online videos, daily videos starring laypeople showed significantly positive impacts on viewers' engagement such as empathy, social presence, and self-enhancement such as self-reflection, psychological empowerment.

Because of the creation and transfer of born-digital records, file unit-based record description practices have changed fundamentally. In this study, we analyzed the archival description practices of The National Archives (TNA) to maintain intellectual control in the digital records management environment and to support the access to records of users. TNA has created an archival description based on ISAD(G) but, for describing born-digital records, it changed the guideline for descriptive cataloging practices. As the method of ISAD(G) cannot adhere to born-digital records, the next-generation descriptive standard, Records in Contexts (RiC), is still being developed by ICA. In addition to international efforts, we need to build an archival description system that fits our environment, especially because since the year 2000, TNA's online cataloging system has changed and ISAD(G) has been modified in this process. This study also proposed continuous monitoring of digital archival descriptions, provides an integrated approach to analog records and digital content and strengthens experimentation and cooperation toward an uncertain digital future.

This study aims to investigate services of presidential archives in Korea for users who utilize holdings of the archives for scholarly purposes, as well as to examine users' perception of the services. For these purposes, the study analyzed the content of 13 U.S. presidential libraries' Web sites in terms of their research services. In addition, it examined the content of a Korean presidential archives' Web site regarding its research services. Telephone interviews of three staff members of the presidential archives were conducted to better understand the services. With this, three users who have written research papers by using presidential records were interviewed by telephone. It was found that federated search services, access by subjects, and related records of search results were considered necessary by users. A variety of digitized records should be provided online and the services needed should be changed from mere processing of FOIA requests to archival reference services to meet users' needs. Congruently, the presidential archives should provide specialized services to offer records relevant to users' research interests and to provide the compilation of selected records crucial for research.

As the demand for finding clearer information amid vast information acquisition increases, the enhancement of academic research services is highly important. In 2019, the Presidential Archives opened the only academic research services among the permanent archives management institutions. This study aims to identify the status of the insufficient use of academic research services implemented in the Presidential Archives, analyze problems and requirements through interviews with users who have used the Presidential Archives for academic purposes and conducted research, suggest a plan to upgrade the research services of the Presidential Archives, and offer a plan to improve the services of archives institutions accordingly. Researchers mostly sought information through an online search, but the information gap was large depending on the background knowledge, and the research scope was reduced because of insufficient information. Moreover, problems occurred regarding search tools, records management, and records disclosure, and most users were unaware of the academic research services. Therefore, the advancement plans entailed reducing the information gap among researchers, improving the search tool functions, creating more detailed descriptions of records, resolving geographic constraints, promoting academic research services and developing content, nurturing subject-specialized archivists, and providing online chatting services.

Aside from serving as a body that monitors and criticizes the government through reviews and comments on public issues, newspapers can also form and spread public opinion. Metadata contains certain picture records and, in the case of local newspapers, the former is an important means of obtaining locality. Furthermore, advertising in newspapers and the way of editing in newspapers can be viewed as a representation of the times. For the value of archiving in newspapers when a documentation strategy is established, the newspaper is considered as a top priority that should be collected. A newspaper archive that will handle preservation and management carries huge significance in many ways. Journalists use them to write articles while scholars can use a newspaper archive for academic purposes. Also, the NIE is a type of a practical usage of such an archive. In the digital age, the newspaper archive has an important position because it is located in the core of MAM, which integrates and manages the media asset. With this, there are prospects that an online archive will perform a new role in the production of newspapers and the management of publishing companies. Korea Integrated News Database System (KINDS), an integrated article database, began its service in 1991, whereas Naver operates an online newspaper archive called "News Library." Initially, KINDS received an enthusiastic response, but nowadays, the utilization ratio continues to decrease because of the omission of some major newspapers, such as Chosun Ilbo and JoongAng Ilbo, and the numerous user interface problems it poses. Despite these, however, the system still presents several advantages. For example, it is easy to access freely because there is a set budget for the public, and accessibility to local papers is simple. A national library consistently carries out the digitalization of time-honored newspapers. In addition, individual newspaper companies have also started the service, but it is not enough for such to be labeled an archive. In the United States (US), "Chronicling America"-led by the Library of Congress with funding from the National Endowment for the Humanities-is in the process of digitalizing historic newspapers. The universities of each state and historical association provide funds to their public library for the digitalization of local papers. In the United Kingdom, the British Library is constructing an online newspaper archive called "The British Newspaper Archive," but unlike the one in the US, this service charges a usage fee. The Joint Information Systems Committee has also invested in "The British Newspaper Archive," and its construction is still ongoing. ProQuest Archiver and Gale NewsVault are the representative platforms because of their efficiency and how they have established the standardization of newspapers. Now, it is time to change the way we understand things, and a drastic investment is required to improve the domestic and international online newspaper archive.

Finding aids are descriptive tools for archival materials in order to physically and intellectually understand and control archival collections. For electronic finding aids, encoded archival description has been developed as part of the Online Archive of California project for direct and comprehensive access to a variety of archival materials across the California state. The purpose of this article are: to understand a brief history of EAD development; to examine EAD encoding, format conversion, structure, and representation used in OAC; and to necessarily suggest that a customized EAD model should be developed for Korean contexts.
