최근 한국 사회는 학문 공동체에서의 연구위반 사례에 대해 잘 알게 되었다. 날조와 표절 등 연구윤리의 스캔들과 연관된 황우석 교수, 전 교육부 장관 김병준, 전 고려대 총장 이필상과 같은 이들에 의해 연구윤리는 중요한 사회적 이슈가 되었다. 먼저 서울대학교 황우석 연구자는 2005년도에 발표된 논문에 데이터의 날조와 변조 활용에 대한 책임을 완전히 시인하였다. 본 논문에서는 황우석 사례를 통해 배운 중요한 교훈으로 데이터의 날조 및 변조의 문제뿐만 아니라 국제적으로 통용될 수 있는 연구윤리 규정의 필요성, 올바른 저자 표시와 공로배분 및 공동 연구자들의 책임감, 인간 인체 대상 실험과 불충분한 보호, 이해갈등이란 연구윤리의 문제 등을 제시하였다. 황우석 사건 이후의 중요한 연구부정 사례로서 김병준 사례가 있다. 김병준 사건의 교훈으로서 표절 자기표절의 기준 문제, 과거 표절 청산과 표절 기준 적용 시점의 문제 등을 제시하였다. 보다 최근의 고려대 이필상 사례는 연구부정행위의 조사 절차와 후속 조치의 문제, 연구지도의 문제, 바람직한 내부고발의 문제 둥을 교훈으로 제시하였다. 이러한 사례들의 개요와 교훈에 대한 결론적 고찰을 통해 다음과 같은 교훈을 제시하였다. 첫째, 연구윤리와 관련된 제도적 정비의 계기 마련이며 둘째, 언론 및 미디어의 역할 제고이다. 셋째, 연구윤리교육의 필요성과 방향성에 대한 모색이다. 정부나 대학 그리고 연구기관이나 학회들은 황우석 사건 및 그 이후의 사례들에서 보이는 여러 연구윤리에 대한 문제점들과 교훈들을 배우고 연구윤리를 위한 교육 프로그램, 가이드라인 그리고 제도적 방책들을 마련해야 할 것이다.

The systems engineering standard process is intended to be customized for a given project environment and system characteristics. This study describes the experience gained by applying systems engineering to government-funded projects. The characteristics of government funded project are lack of common development process among the participating organizations and mechanism to determine system requirements. This study describes the contents of the systems engineering activities, including development of operational concept, system requirements, verification requirements (test cases), test verification plan, and implementation of system test and lessons learned from these activities.

This paper presents a case study in which a lesson was designed and applied to enhance preservice home economics teachers' instructional design competence using the metaverse. For 15 weeks from March 6 to June 14, 14 students enrolled on the course 'Multimedia Home Economics Education' for preservice home economics teachers used the metaverse to engage in problem-based learning to solve instructional design problems in home economics classes. In accordance with the ADDIE design model, in the analysis stage, we assessed preservice home economics teachers' level of knowledge of lessons using the metaverse, and their perceptions of the possibility, necessity, and usefulness of using the metaverse in home economics lessons. In the design and development stage, lesson plans, questions for problem-based learning, assessment tools, and teaching and learning materials were developed. The implementation was conducted in parallel with training on understanding multimedia and the metaverse, and instructional design competence was evaluated through pre- and post-testing and reflection journals. The results revealed that the preservice home economics teachers acquired a good understanding of lessons using the metaverse, learned how to design lessons for self-directed learning by applying the metaverse to their home and classroom, and gained confidence in applying it to their teaching practice or in-service work. It is expected that the results of this study will be used as support materials for prospective and current home economics teachers to design home economics lessons using the metaverse, thereby expanding the horizons of home economics education.

The numbers of geogrid-reinforced walls are widely used in Korea. This papers present the results of two failure case histories of geogrid-reinforced segmental retaining walls. The geological background of the construction sites, detailed construction sequences, and the amount of rainfall were examined. The failure of these reinforced walls are caused by the improper drainage system and foundation treatment, too sharpened curvature of corner work, and too high height of wall.

본 연구에서는 석유화학제품 산적운송선(화학유조선)에 의한 해상운송 과정에서 발생한 위험·유해물질(HNS) 관련 해상화학사고에 대하여 국내 및 국외의 주요 사례를 조사·분석함으로써 얻은 교훈을 소개하고, 이러한 교훈을 바탕으로 국내 해상HNS 교육과정 개선방안을 제시하였다. 6건의 사고사례를 통하여 얻은 교훈을 1) 사고관련정보, 2) 안전, 3) 오염, 4) 대응, 5) 구난, 6) 기타와 같은 6개 분야로 분류하였다. 각 분야의 세부항목별로 요약된 교훈을 바탕으로 해양환경교육원(MERTI) 유해액체물질운반선 해양오염방지관리인 교육과정을 현행 8개 교과목(16시간)의 2일간 교육을 16개 교과목(24시간)의 3일간 교육으로 개선하는 방안을 제시하였으며, 또한 해양경찰교육원(KCGA) 전문교육 해양화학사고대응 과정을 현행 15개 교과목(35시간)의 5일간 교육을 32개 교과목(48시간)의 6일간 교육으로 개선하는 방안을 제시하였다. 이러한 연구결과는 해상화학사고 대응에 관한 경험과 교훈을 서로 공유하는 데에 기여하고, 해상HNS사고에 대비한 대응 인력 교육·훈련과정 개선의 기초자료로 활용될 수 있을 것으로 기대된다.

본 논문은 나노급 큐브위성 시스템 및 유닛의 발사환경시험 사례를 통해 얻을 수 있는 설계와 제작의 교훈들을 소개한다. 일반적으로 초소형위성은 발사관에 담겨 발사되므로 발사 시 외부 하중 역시 발사관을 통해 내부의 위성에 전달된다. 이러한 특성으로 인해 초소형위성은 외부 가진에 비해 과도한 하중을 받을 수 있고 기계적 파손의 가능성을 높인다. 여기서는 진동시험 사례를 통해 초소형위성 설계와 제작 시 지켜야 할 여러 지침들을 보여준다. 그리고 내부 위성을 고정하는 현대적인 기능이 적용된 발사관과 전통적인 발사관의 시험 결과를 비교함으로써 발사관 선정에도 하나의 권고를 제시한다.

The construction failures can be decreased through continuous improvement of construction process based upon the information of construction failures. Herein, the information of construction failures can be utilized as the key factor for identifying and enhancing various ineffective construction processes that can prevent failures. This research proposes a process model for the continuous improvement of construction processes by using construction failure information. Extensive reviews and analyses of literatures related to construction failures are performed to investigate its definition, type, cause, and lessons learned. This research adapts process modeling methodology and case-based reasoning for the development of the proposed CIMCP(continuous improvement model of construction process), and then suggests its framework that contains modules of case retrieval, case index, and case adaptation.

This study aims to provide the results of a case study, based on the action research approach, in which an user-oriented management system for enterprise information systems operational performance is successful developed and applied. This study performs the research and summarizes the results by adopting 5-step approach of action research, i.e., diagnosing, action planning, action taking, evaluating and specifying learning. The most important lessons learned from the study include (1) operation performance measures should be established to be shared by the management and users; (2) evaluation and improvement activities should be performed continually; and (3) formula to calculate the measure should be evolved so that improvement initiatives can be identified. The results of the study are expected to provide the companies intending to develop a management system for enterprise information systems operational performance with the practical and useful information. In addition, it is expected to suggest the research results that can be utilized as a basis for future research in this area.

This paper describes a case study on the R&D programs of fighter and attacker aircraft such as F-22A, F/A-18E/F, and T/A-50. F-22A and F/A-18E/F were developed in same age. The performance of each program was, however extremely different. F-22A program results in a lot of cost overrun and schedule delay. On the other hand F/A-18E/F program met the cost, schedule, and performance goals. In the T/A-50 program with a super-sonic advanced trainer, T-50 was also developed successfully on planned cost and time by Korea Air-force and KAI. This paper derives key elements for the success of the military aircraft R&D program through lessons learned from th e case study. Each program is analyzed in terms of its background, planning and management.

The Unmanned Air Vehicle (UAV) systems are indispensable tools of air surveillance and reconnaissance nowadays. Via this systems, hazardous end risky intelligence gathering activities are handled easily. Although they are named as "Unmanned" the UAV systems are commanded by pilots/operators. So, because of weather conditions, enemy attacks etc. as well as pilot error it is possible to face with sudden Round per Minute (RPM) drops and subsequently engine cut/stop during a mission flight at high altitudes. In this case, there are some very urgent decisions to make and rapid "emergency procedure" steps to take in a very short time before Line of Sight (LOS) is lost. The time before crash and the distance to landing air base need to be calculated, the Return Home route need to be checked and the landing/crash side need to be determined. Therefore it is a vital necessity that UAV pilots have some extra qualifications like being determined, well instructed and trained, experienced apart from operating ability. Within this scope, for an education process of a UAV pilot experience sharing and lessons learned are as important as simulators even more. By means of lessons learned it is possible to find out the reasons, mistakes and prevent the likely UAV accidents. In this study it is told about a real UAV crash, experienced of the pilot, the dos and don'ts and the difficulties. Thus it is aimed to help the people who can experience the same or similar situations in future.
