최근 위변조에 의한 본인 인증 관련 사고가 급증하였으며 지문인식 밑 기타 다양한 인증시스템이 연구되고 있다. 최근에는 사람의 지정맥을 활용한 인증 시스템의 개발에 차세대 인증 시스템으로 연구가 활발히 진행되고 있다. 지정맥 인증 기술은 손가락 두 번째 마디 내 정맥을 말한다. 지정맥의 특성은 겉으로 보이지 않고 사람마다 패턴이 다르기 때문에 위 변조가 불가능하다. 뿐만아니라 지정맥 인증은 인증 절차가 간단하고, 보안성이 매우 높은 것으로 알려져 있다. 본 연구는 기존 지문을 이용한 출/퇴근 정보는 각종 관련 사고를 유발 시킬 수 있음을 방지하고자 지정맥을 이용한 본인 인증에 대한 보안성을 높이고, 각종 부당 취득 사고(추가근무)를 미연에 방지할 수 있으며, 지정맥을 이용해 출입/퇴근 시간을 기록하며 기록된 데이터로 지각/추가 근무 시간을 정확하게 측정 할 수 있다. 본 논문의 연구 결과물을 통해서 지정맥을 이용한 출/퇴근 정보를 데이터베이스/엑셀/텍스트에 저장하고, 기록된 정보를 이용해 지각/추가근무 시간을 정확하게 산출하여 각종사고를 미연에 방지할 수 있음을 확인하였다.

Two species of Argyresthia, A. subrimosa Meyrick and A. umbrina Liu, Wang et Li are reported for the first time from Korea. The collecting data show that A. subrimosa occurs in two remote islands, Ulleungdo and Jejudo in the country. These two local populations are compared with each other in external and genital morphology. Argyresthia umbrina is first recorded outside the type country, China. Photographs of the habitus and genitalia are provided for the two species treated here.

In terms of archiving. an importance of the Web is more increasing. Since the Internet has been popularized. many archivists have made efforts to preserve informational. cultural. and evidential values of the Web. Information resources on the Web raise archival issues that are significantly different from issues of preservation for tangible materials, because they are based on unique characteristics of the Web. One of issues is about a technical aspect which is based on technical architecture of Web. Another important issue is related to legal problems including copyright, authenticity and so on. In this context. it is essential to understand technical and legal characteristics of the Web. A purpose of this article is to review technical and legal aspects of Web archiving and to find an agenda for development of Web archiving.

For the purpose of technological analysis in the marine accidents and their prevention, IMO have made it obligatory to load VDR which is similar to the black box in aircraft. However, in case of body sinkage, capsizing, stranding and plunging which are almost 10% of marine accidents, it is difficult to take out the necessary data from the VDR in order to analyze the cause of them. Therefore, this paper apply the navigation dangerousness evaluation technology to the VDR to improve its performance. And we suggest that the vertical acceleration which is one of the factors for evaluating seakeeping performance of a ship is to be added in the existing VDR record data recommended by IMQ.

In light of the recent advancement in networking and information technology, the direct information request through website has increasingly proven to be the preferred means over visiting physical archives. Thus, the proper utilization of a communication tool capable of sufficiently capturing user feedback and requests is an absolute necessity. This paper examines the availability and utilization of alternative user participatory communication tools in government websites with particular focus on the archives in South Korea, the United States, the United Kingdom, Canada, China, and Japan. In assessing the use of alternative user participatory communication tools in these archives, we examined the availability of communication mediums other than the online forums, email, and telephone with particular focus on social media tools that may offer a degree of familiarity for the user. Our research indicates that the most frequently utilized social media tool is Facebook while the archive offering the greatest variety of alternative user participatory communication tools was the United States archive.

Due to the development of digital technology, users can record their daily lives without being restricted by time and space. The trend is growing rapidly, but lifelogging cases are still insufficient. Google's Timeline and domestic application 'Daily' were analyzed through in-depth interviews. Based on the Creating Pleasurable Interface Model, the factors influencing user satisfaction were identified by the Reckard 7-point scale based on the Honeycomb model. The results of the in-depth interviews and the 7-point scale were similar, and we could see what and why users preferred the recording application. This study is meaningful to evaluate the user experience for recording application and analyzing the needs of users obtained through in-depth interviews to assess the usability that provide a service record and recall.

It is described that the total analysis of CD-R, a digital recording media, including the planning and performing chemical analysis of cross sectional structure of recording layer, dye composition and chemical structure as an example of design for chemical analysis. Since chemical analysis of unknown sample is often involved the complicated process requiring many experiences and knowledge, students feel difficulties in planning the procedure of chemical analysis and selecting analytical methods. Thus, an example of chemical analysis is provided here to help student understanding the hole procedure of CD-R analysis. In this study, SEM is used to determine the cross sectional structure of PC substrate and recoding layer of CD-R. The dyes in recording layer is dissolved with solvent and separated with using TLC, analyzed with using UV-Vis absorption spectrometer. Then, the chemical structure of each component is determined with using GC-MS, NMR and mass spectrometer.

As technology develops, U.S. state archives are using their websites to provide more and more information to state government agencies and the public, and more remote users are accessing and utilizing these websites. This study is the first to investigate how U.S. state archives collect information on their users and use of their archives and how they employ their websites to publicize these activities and their results for their own advocacy. Data was collected by examining and analyzing websites of all U.S. state archives, and the collected data was analyzed by content analysis and NVivo8 software. This study indicates that the websites of most state archives present little information on their users and usage of their archives and that U.S. state archive websites need to employ their websites for advocacy more effectively.

The purpose of this study is to study the technical implementation methods to prevent problems such as the record of important educational activities of the student life record department or the continuous illegal leakage and manipulation. To this end, in this paper, by applying a private blockchain that can be participated only by a given organization or individual, it prevents outsiders from participating in the block network, and creates legitimate authority by creating two types of block data: student information block and access record block in the life record book. We proposed a block mechanism that can be registered, modified, and accessed only by authorized staff members. As a result, we have prepared an alternative to prevent forgery and alteration of the living records by third parties and to secure the integrity of the living records. If applied to the educational administrative information system, social consensus will be established that the operation and management of the life record book is reliable.
