Librarian certification in Korea is issued by the LIS Departments, the Academy of Librarianship, and the Academic Credit Bank system; however, it has been pointed out that there is a limit to how much these nurture high quality librarians, because the education quality and contents varies from education institutions and there is no verification method for certification issued by educational programs. Therefore, this study investigated certification systems of academic or training programs that are conducted at home and abroad, analyzed how the certification systems are oriented, what the purpose and criteria of the certification systems are, and what the content of assessment is. As a result of this investigation, several areas needing change were identified which if adopted can improve the system. These included making amendments to the library laws related to the certification system, substantially revising the relevant enforcement ordinance, making changes to the selection of the Certification authority, establishing certification standards and procedures, developing contents related to document examination and due diligence audits, rating the effects of the certification system, and setting standards. Improving the Librarian Certification System has been discussed over the past 20 years and should not be delayed any longer because of the university structural reform of the current government, the rapid rise of the qualified librarians, decreasing employment due to the human resources supply and demand imbalances, all of which has resulted in a survival crisis of four-year Department of Library and Information Science.

The M&S (Model and Simulation) has been increasingly used in the wide area of applications and the official certification or accreditation of the M&S are becoming a mandatory requirement to prevent the risks and mishaps caused by the usage of inadequate M&Ss or by misuses of the M&S. This paper threats the VV&A (Verification, Validation, and Accreditation) for the M&S used in the development of the aerospace systems, where most M&S used in the development are derived from the physical laws and the final validation data are typically obtained through a series of flight tests after the prototype production. Considering these unique features, the paper proposes the M&S life-cycle model and development paradigm suitable for the aerospace-system development and accesses the proposed ones by comparative investigation on the relevant regulations and related literatures.

Currently, in the most mail automatic processing centers, after facing and canceling, envelope mail is passed through an Optical Character Recognition/Barcode Sorter(OCR/BS) to read the address and 3 of 5 fluorescent(luminescent) barcode is applied. Normally, 30%∼35% of this mail is rejected. The usual reasons for read failure are poor printing quality of address and barcode, script printing and failure to locate the address. This paper describes a verification system of the postal 3 of 5 customer barcode for solving this problem. The certification system of the 3 of 5 customer barcode consists of barcode verification system and postal address database. The purpose of certification system of the customer barcode verifies the postal 3 of 5 customer barcode and tests matching of mail piece postal address, and retrieves postal code.

The aircraft gas turbine engines with the Electronic Engine Controls(EEC) had been developed to save fuel and enhance their performance in the early days, and had employed the health monitoring function in the Full Authority Digital Engine Controls(FADEC) to improve their reliability. This has led to an increasing demand for the certification technology of these controls. The design and certification issues of power supply, aircraft supplied data, failure modes, software verification/validation, and lightning requirements need to be addressed. This paper presents the design considerations and the certification techniques applied to the electronic engine controls. And it is believed that this paper will be basis to establish a requirement in Korean Airworthiness Standard.

In this paper we propose an international cross certification model using cross certificate. We propose a new model by analyzing and solving current problems of the National PKI. We recommend a certificate profile, design a directory schema, and propose a method to access PSE(personal security environment) using PKCS＃11, which gives the expansibility and convenience. Finally, we propose a certificate path verification method using RFC 3280 and show how to get the certificate chain by using the trust anchor. This model is recommended to the detailed level of specification for the interoperability of each country's PKI.

Existing environmental measuring devices mainly focus on electromagnetic wave and eco-friendly product certification and durability test, and sensor reliability verification and verification of measurement data are conducted mainly through sensor performance evaluation through type approval and registration, acceptance test, initial calibration, and periodic test. This platform has established an ICT-based environmental monitoring sensor reliability verification system that supports not only performance evaluation for each target sensor, but also a verification system for sensor data reliability. A sensor board to collect sensor data for environmental information was produced, and a sensor and data reliability evaluation and verification service system was standardized. In addition, to evaluate and verify the reliability of sensor data based on ICT, a sensor data platform monitoring prototype using LoRa communication was produced, and the test was conducted in smart cities. To analyze the data received through the system, an optimization algorithm was developed using machine learning. Through this, a sensor big data analysis system is established for reliability verification, and the foundation for an integrated evaluation and verification system is provide.

Recently ubiquitous application services are developed plentifully using RFID techniques in the field of distribution and security industries. However, except these field the applications using RFID are not mature yet. In this study, we proposed a real-time context service model of the u-conference based on the real-time contextual information acquired from conference and exposition. With collection of real-time contextual information for u-conference, the model can provide a lot of information services on the state of session attendee, doorway control, affairs, user certification, presentation progress etc. For the verification of proposed real-time context service model of u-conference, we design and implement the conference progress state service included the state of session attendee, user certification and presentation progress etc. This service provides the presentation state information included the current presenter, the paper list, the number of session attendee, the schedule and place of each session using the collecting RFID tag and the related information.

Pipe support is a representative structure that supports slab formwork, and it is a representative temporary equipment that has been systematically managed since the 1990s when the domestic temporary equipment performance test system was introduced. Nevertheless, it is also a reality that many of the products in circulation are used products that are reused and do not meet the performance of the initial manufacturing stage. However, if only new products are insisted, it could lead to delays in the process due to an increase in construction costs and difficulties in timely delivery. On the contrary, it is not acceptable for the safety of the construction site to use products of low quality without verification procedures or standards. Therefore, this study attempts to grasp the management system such as safety certification for temporary equipment and the actual condition of quality control to maintain performance, and propose improvement plans.

최근 중요 인프라 업계에서 주로 다뤄지는 제어시스템을 표적으로 한 사이버 공격으로 Stuxnet에 이어 Havex RAT, BlackEnergy2 라고 하는 멀웨어(Malware)를 이용한 사건이 많이 증가하고 있다. 제어시스템의 새로운 공격 방법에 대한 대책으로 시스템 입구와 내부조직에 대한 대책을 강화하기 위한 필요성이 요구되어 왔지만 그러한 대책은 한정되어 있다. 본 논문에서는 보안대책에 필요한 인증 취득에 있어서 기준이 되는 국제 표준인 ISASecure(R)EDSA 인증제도에 착목했다. 인증평가는 요구요건이 중복되는 불필요한 인증평가 작업을 최소화 하는 것으로 인증 취득 시 발생되는 코스트를 절감할 수 있으며 기존의 정보 보안 관리체계(lSMS)의 인증을 취득하고 있는 기업이나 조직이면 제어시스템의 인증 기준으로 추가된 차분 요건만으로 취득이 가능 할 수 있을 것으로 상정된다. 이러한 제어시스템의 보안을 구현하기 위해 IACS(Industrial Automation and Control System)에서 표준화로 제정한 IEC62443 시리즈를 참조하여 세계각국에서 사용되는 제어시스템을 대상으로 인증(EDSA) 요구사항의 차분을 도출하는 수법을 제안하고자 한다.
