최근에는 개인 프라이버시 보호에 대한 관심이 증가하면서 사용자 익명성을 제공하는 스마트카드 기반인증 프로토콜에 대한 연구가 활발하게 진행되고 있다. 원격시스템 인증프로토콜에서 사용자 익명성을 제공하기 위한 스마트카드 기반 인증 프로토콜을 Das등이 처음 제안하였지만, Das등의 프로토콜은 사용자 익명성을 제공하지 못한다는 문제점이 제기되고, Chien 등은 이러한 문제점을 해결하기 위한 새로운 프로토콜을 제안하였다. 사용자 익명성이 제공되면서 악의적인 사용자를 감지하는 것이 어려워지고, 이러한 문제점을 해결하기 위해 Kim 등은 추적 가능한 인증 프로토콜을 제안하였다. 본 논문에서는 Kim 프로토콜의 사용자 익명성과 내부자공격에 대한 문제점을 제기하고, 이러한 문제점을 해결하기 위한 새로운 프로토콜을 제안하고, 제안한 프로토콜의 안전성 및 효율성을 비교 분석한다. 제안한 프로토콜은 사용자 익명성을 제공하면서 추적 가능한 인증프로토콜로 Kim 프로토콜에 비해 안전성 측면에서 더 효율적이다.

오늘날 기업의 비즈니스 환경은 시장, 기술 및 사회에서 오는 여러 가지 요인들로 인하여 한층 더 복잡해지고 있다. 비즈니스 패러다임의 변화에 따른 빠른 시장 대응(Time-to Market)에의 요구 증가 및 비용 감소, 높은 생산성에 대한 요구 증가, 재사용성 증대를 통한 유연한 애플리케이션을 개발할 수 있는 절차와 매커니즘에 대한 필요성이 대두되고 있다. UML 기반의 객체지향 소프트웨어 개발 생명주기에서 요구사항 추적 매트릭스 설계(RTMD : Requirement Tracing Matrix Design) 모델을 제시하여 실제업무에 적용하였다. 이 방법은 소프트웨어 개발의 생산성 향상 및 유지보수 비용을 절감하는 효과가 있다. 그러나 관련 문서들의 완전성(completeness), 일관성(consistency), 정확성(correctness)을 검증하기 위한 절차 및 규칙이 미흡하며, 또한 이들 명세서들은 보다 체계적으로 관리할 수 있는 자동화된 시스템을 필요로 한다.

The objective of this study is to examine the effects of consumer beliefs regarding three food certifications on their behavioral intention and the behavioral intention biases to purchase (purchasing intention biases) certified agricultural products as predicted by a subjective probability model. The food certifications used for this study are 'Organic food', 'Traceability system of food products,' and 'Hazard Analysis Critical Control Point (HACCP)'. Tofu (bean curd) was selected as being representative of agricultural food products, for the purposes of this study. In 2016, we surveyed 243 consumers regarding the strength of their belief regarding their prior beliefs relative to each certification, as well as the strength of their intention to purchase certified tofu based on their belief strengths for this study. The study resulted in the following findings: Firstly, consumers hold more than two different prior beliefs for each of the three certifications included in this study. Consumers' prior beliefs regarding these certifications have an impact on their consideration as to whether they plan to buy those certified agricultural products. Secondly, consumers try to persuade themselves to ensure that their particular belief about the product's certification could lead to a purchasing decision regarding that agricultural product.

정보시스템 구축 프로젝트의 복잡성과 규모가 점차 커지면서, 프로젝트가 실패하는 경우가 발생한다. 프로젝트의 실패의 원인을 분석해보면 사용자의 프로젝트 이해 부족, 불명확한 요구사항 및 요구사항변경 등으로 소프트웨어 개발 생명주기 중 요구사항 분석 단계에서 대부분의 원인을 찾을 수 있다. 본 논문은 소프트웨어 개발 프로젝트에서 요구분석을 통해 도출된 기능과 변경요구 기능간의 추적 등 개발 생명주기 전체 기간 동안 지속적인 요구사항 변경 관리가 가능하게 하는 도구를 설계하였다. 그리고 프로젝트 관련자들 사이에서 충분한 합의와 협의를 통해 공통의 이해를 구축하는 효과적인 의사소통을 지원하는데 필요한 기능에 대해 논의한다.

Lightning impulse voltage is essential to evaluate the insulation performance of electric power apparatus. Recently international standard (IEC-60) on high voltage measurement techniques are being revised. In the draft of this standard, a new calibration method is introduced and the accuracy of most industrial measuring systems is maintained by means of comparison test against the reference measuring systems. Comparison tests of dividers for chopped lightning impulse measurement were rallied out by KERI. The 700kV shielded resisitive divider with and without compensation element were done comparison test with 300kV PTB divider which have the similar charateristics as that were circulated among the laboratories. This paper reports on the calculation results of response charateristics obtained by EMTP and the comparison test results with chopped lightning impulse voltages from 150kV to 250kV. It is demonstrated that KERI are capable of realizing the idea in the revision of the IEC standand, that is, to establish traceability.

GLP regulations were initially “promulgated to address assuring the validity of data in the wake of investigations by EPA and FDA during the mid -1970's which revealed that some studies submitted to the agencies had not been conducted in accordance with acceptable laboratory practices.” [1] In the early 1970s, results of an investigation by the FDA in about 40 laboratories revealed many cases of badly managed studies, poor training of personnel and some cases of deliberate fraud. The general findings were that there were poorly trained study directors and study personnel, poorly designed protocols, protocols not followed, procedures not conducted as described, raw data badly collected, data not correctly identified, data without traceability, data not verified and approved by responsible persons, lack of standardised procedures, poor animal husbandry, inadequate characterisation of test items and test systems, inadequate resources, equipment poorly calibrated or otherwise qualified, reports not sufficiently verified, not an accurate account of the actual study, not a proper reflection of raw data and inadequate archiving of data. These problems are not just past history, since they resurface time and time again, even in quite recent times as the experience of GLP inspectors shows [1]. The GLPs specify minimum practices and procedures in order to ensure the quality and integrity of data submitted in accordance with a regulatory requirement

Purpose: For effective quality assurance activities, BOM-based quality assurance method is presented. This study introduces various BOM conversions such as Q-BOM, T-BOM, and S-BOM based on M-BOM structure. Methods: Product quality control via Q-BOM manages inspection/audit information, overall supply-chain of product, part requirements, and inventory status. T-BOM manages part traceability, and S-BOM enables statistical control over key process and parts at various hierarchy levels. Results: Quality plan template was developed based on the study results of BOM system including Q-BOM, T-BOM, and S-BOM. Conclusion: Through BOM(Q-BOM, T-BOM, and S-BOM) study and development of quality plan template, more systematic and comprehensive quality management plan is achieved.

The purpose of this study is to find food safety approach in the Eco-label Chain of Custody(CoC) which is only focused to traceability. Because, consumers want to be assured the certified seafood comes from sustainable fishery as well as hygienic. In order to this approach, we used Analytic Hierarchy Process(AHP) method as belows. We first understood the CoC criteria for using pair-wise comparison and analyzed and selected each Eco-label certifications and standards. Second, we carried out a survey to the targeted standard Marine Stewardship Council(MSC) CoC auditors all over the world and analyzed the priorities of food safety approach to 4 principles and 12 criteria belong the MSC CoC Standard. As the results, we found out that 'Management System' has the highest priority in the principles and 'Documentation' and 'Keeping Record' are the most important criteria for this approach. In addition, 'Training' and 'Identification' are also higher priority of criteria. So, we suggested food safety approach method for improvement of these criteria in conclusion based on discussion with specialist in this field.

The work environment of locomotive cabs has long been an important issue in the design of railload systems since it is quite critical in terms of system's operational safety. It is getting more attention as the running speed of the trains goes up these days. To this end, this paper describes how to systematically construct a DB for the requirements set in the course of the improvement process for the aforementioned cab work environment. As a solution approach, we have adopted the requirement architecture concept to cover the whole activities required to do such as in requirements generation, DB construction, change management, and traceability management. Specifically, based on the requirement architecture framework a requirement process to collect requirements for improvement is discussed, and the guide lines are suggested for verification and validation of the developed requirements. In addition, a base schema and requirements templates are developed, which will be used in generating requirements and constructing a DB. Finally, it is demonstrated how the requirements DB for locomotive cabs can be constructed using a computer-aided tool in an integrated fashion.

본 논문에서는 전기 및 전자 쓰레기의 대책으로 Printed Circuit Board (PCB) 부착형 Radio-Frequency Identification (RFID) 태그 칩을 이용한 사물인터넷 디바이스 생산 공정에 대한 모델을 제안한다. 전기 및 전자제품은 PCB 부품실장 공정과 검사가 필요하다. 또한 현재 제조사들이 사용하는 바코드 시스템은 Surface Mount Technology (SMT)공정이 완료되기 전까지 PCB 이력 관리가 불가능하다. 논문에서 제안한 PCB 부착형 RFID 태그 칩을 이용한 사물인터넷 디바이스 생산 공정 모델은 바코드 방식과 같은 출력-부착 단계가 필요하지 않다. 태그 칩은 각 단계의 공정 데이터가 기록될 수 있고, 데이터베이스 시스템 (DBMS) 접속 횟수를 현격히 줄일 수 있다.
