  • The target of managing electronic records should be the trusted record services to the end-users. The natural characteristics of electronic records yields the drawback in the authenticity aspect and in the integrity aspect, and current standards and methodologies have beed developed to treat this drawback. However the authenticity and the integrity concepts is hardly separated each other and too completed, so alternative "source" concept is introduced and a verification strategy for the origin of electronic records is discussed in this paper. According to this concept, current standards and methodologies may be criticized for the negligence of necessary information organizing/verification, the doubtful long-term verification, and the missing counter-strategy for the verification-failed records. To solve this, needed facters for origin verification is described, new preservation format divided into temporally-fluctuating (variable) part and immutable (fixed) part is proposed, and a strategy to prevent, avoidance, and detection/recovery important records is suggested.

  • 부인가능 인증은 수신자가 전송된 메시지에 대한 출처를 확인할 수 있지만, 제 3 자에게는 전송된 메시지의 출처를 증명할 수 없는 인증 메커니즘이다. 이러한 부인가능 인증을 통하여 프라이버시 노출 가능한 전자투표와 전자상거래에서 메시지 전송에 대한 익명성을 보장할 수 있다. 본 논문에서는 그룹 멤버의 익명성을 보장하기 위한 환 서명을 이용하여 부인 가능한 서명을 제안함으로써 서명자의 프라이버시를 보호한다. 또한 추후에 서명에 대한 출처 확인이 필요할 경우, 서명자가 서명 생성을 위한 지식을 증명함으로써 서명에 대한 출처를 제 3 자에게 증명할 수 있다.

  • Source memory is a cognitive process that combines the representation of the origin of the episodic experience with an item. By studying this daily process, researchers have made fundamental discoveries that make up the foundation of brain and behavior research, such as executive function and binding. In this paper, we review and conduct a bibliometric analysis on source memory papers published from 1989 to 2020. This review is based on keyword co-occurrence networks and author citation networks, providing an in-depth overview of the development of source memory research and future directions. This bibliometric analysis discovers a change in the research trends: while research prior to 2010 focused on individuality of source memory as a cognitive function, more recent papers focus more on the implication of source memory as it pertains to connectivity between disparate brain regions and to social neuroscience. Keyword network analysis shows that aging and executive function are continued topics of interest, although frameworks in which they are viewed have shifted to include developmental psychology and meta memory. The use of theories and models provided by source memory research seem essential for the future development of cognitive enhancement tools within and outside of the field of Psychology.

  • 시청각기록물은 기존 문서기록물과 달리 생생한 현장감을 전달할 수 있고 사용자들의 관심을 끌 수 있는 장점이 있다. 그러나 전자시청 각기록물은 원본과 똑같은 품질의 사본들이 많이 만들어지게 되어 위변조가 쉽고 불법복제 및 배포가 가능하기 때문에 기록물관리에 주의를 기울여야 한다. 이러한 문제를 해결하기 위한 방안들로서 DRM과 워터마킹기술이 주목을 받게 되었다. 본 논문에서는 시청각기록물 중에서 동영상 시청각 기록물에 적용 가능한 워터마킹 기술을 제안한다. 본 논문에서 제시한 워터마킹 기술은 원본영상신호의 복제신호를 추출하여 워터마크 정보를 삽입하는 방법을 취했다. 전자시청각 기록물 출처확인 및 무단배포에 따른 저작권 권리 추적을 위한 기술로서 다양한 실험을 통하여 가능성을 점검하였다. 원본 신호에서 추출된 신호를 이용하여 워터마크 정보를 삽입하기 때문에 화질훼손이 적고 압축알고리즘에 강인한 특성을 갖고 있다. 실험결과를 통해서 원본보존을 중요시하는 시청각기록물관리 분야에서 적용 가능성을 제시하였다.

  • This paper was investigated by comparing "Sok-Mong-Gu Bun-Ju"(續蒙求分註) and "Mong-Gu"(蒙求). As a result, "Mong-Gu" was organized around the person anecdotes, "Sok-Mong-Gu Bun-Ju" is annotated with the person anecdotes. So the text show an differences were found on the configuration. Thus It reveal that "Sok-Mong-Gu Bun-Ju" is a tome and convenient to use the report has been made by scholars can be clarified.

  • This article shows how the tradition of German historicism and positive historical science contributed to the establishment of German archival system, especially the principle of provenance and original order. The theory of historicism focused on the recognition and realization of the individuality of the history as a whole unit which is made up of the mutually and organically organized cultural entities. The theory of historicism as this kind of world view got its academic basis from the methodology of the positive historical science, namely the critical reviews on the archival sources which exist in mutually and organically organized record entities. In this context, the scholars of the historicism saw the establishment of the efficient archival systems as necessary. To some great degree, the emergence of the principle of the provenance and original order was its logical result. The author of this paper tried to highlight this point of view historically, on the basis of the activities of Ranke, Sybel and Lehmann around and in the Prussia Privy State Archives throughout the 19th century.

  • 살모넬라는 여러 가지 전염병 중의 하나이다. 살모넬라 오염을 막는 것이 제일 중요한 일이 된 적이 있었다. 과거에는 사료에서 살모넬라가 감염된다는 사실을 쉽게 공개하기가 어려웠으나 다행히도 이제는 문제 해결을 위해 다양하게 다루어도 된다는 것이 살모넬라 감염원인을 밝히는데 큰 도움이 된다. 살모넬라는 주위의 조건이 적당하면 빠른 속도로 증식이 가능한 세균이다. 살모넬라 감염을 해결하는데는 사료의 출처를 조사해야 한다는 것이 확인이 되었고 처리방법에는 비용이 적게드는 열처리방법이 사용되고 있다.

  • Public key infrastructure(PKI), principle technology of the certificate, is a security technology providing functions such as identification, non-repudiation, and anti-forgery of electronic documents on the Internet. Our government and financial organizations use PKI authentication using ActiveX to prevent security accident on the Internet service. However, like ActiveX, plug-in technology is vulnerable to security and inconvenience since it is only serviceable to certain browser. Therefore, the research on HTML5 authentication system has been conducted actively. Recently, domestic bank introduced PKI authentication complying with web standard for the first time. However, it still has inconvenience to register a certification on each website because of same origin policy of web storage. This paper proposes the certificate based SSO protocol that complying with web standard to provide user authentication using certificate on several sites by going around same origin policy and its security proof.

  • Sharing cross-site resources has been adopted by many recent websites in the forms of service-mashup and social network services. In this change, exploitation of the new vulnerabilities increases, which includes inserting malicious codes into the interaction points between clients and services instead of attacking the websites directly. In this paper, we present a system model to identify malicious script codes in the web contents by means of a remote verification while the web contents downloaded from multiple trusted origins are executed in a client's browser space. Our system classifies verification items according to the origin of request based on the information on the service code implementation and stores the verification results into three databases composed of white, gray, and black lists. Through the experimental evaluations, we have confirmed that our system provides clients with increased security by effectively detecting malicious scripts in the mashup web environment.

  • Naturally occurring sulfur dioxide in medicinal herbs(crude drug materials) and its origin was investigated. Sulfur dioxide content in 28 kinds (101 samples) of medicinal herbs was studied by two different methods, Monnier-Williams and acid-distillation ion chromatography. Generally, less than 5 ppm of sulfur dioxide was found from the tested herbs. In some herbs, Monnier-Williams method showed higher level of sulfur dioxide than acid-distillation ion chromatography probably due to the presence of volatile organic acid presence in herbs. Naturally occurring sulfur dioxide measured in medicinal herbs may be derived from sulfur compounds of medicinal herbs.
