Systematic performance evaluation of the Defense Acquisition Program is very important, since they are directly related to national security. In this paper, we reviewed various performance evaluation models from a methodological perspective for pragmatic performance evaluation, and the limitations of each model. In order to evaluate the performance of the Defense acquisition program efficiently, especially for the Naval ship Projects and considering their unique characteristics, both various stakeholders' participation, standard indicators for performance measurement, and tailoring them considering the projects' circumstances are necessary. We also propose indicators, contents, and detailed criteria example for the Requirements management. This approach enables a pragmatic and consistent evaluation of defense projects, and through this, meaningful insights could be acquired with accumulate data.

In this study, in order to perform more efficiently reliability design and integrity assessment of structural members, the relational database management program on the engineering plastics was constructed. This program contained 476 grades for 14 kinds of the engineering plastics and was developed using MS-access and MS-visualbasic. This program consists of 3 modules; search condition, probabilistic characteristics of material property, evaluation of P-S-N curve. We perform fatigue test for probabilistic durability analysis and this results input the database program to estimate P-S-N.

Two extreme and one mixed procedures for designing a noise hazard prevention program are discussed in this paper. The two extreme design procedures (engineering-based and HPD-based) yield upper and lower bounds of the total noise control cost, respectively; while the mixed design procedure provides an optimal noise hazard prevention program within a given total budget. The upper bound of the workforce size for job rotation is approximated using a heuristic procedure. Six optimization models are developed and utilized by the mixed procedure to eliminate or reduce excessive noise levels (or noise exposures) in an industrial workplace. The mixed procedure also follows the OSHA’s hierarchy of noise control. A numerical example is given to demonstrate the application of the proposed design procedures.

According to the Korea Augmentation Satellite System (KASS) system milestone, Site Acceptance Test (SAT) has three steps test until the end of the project. SAT#1 is the first time of SAT steps and verify the KASS Reference Station (KRS) and Sub System (S/S) for the monitoring and controllable. After the equipment and software were installed at the Mission Control Center (MCC) with Central Monitoring and Control Simulator (CMS) for the SAT#1, the 1:1 test was progressed when the KRS and S/S are ready to test. SAT#1 has a 10 steps test case and it was progressed each KRS sites. The test was finished throughout the real-time monitoring and the data collection including the data analysis all of the 7 KRS sites. Finally SAT#1 was completed on December 2020 with successfully.

국제학업성취도 비교 연구에 따르면 우리나라 학생들은 과학 수학교과에서 높은 수준의 학업성취결과를 나타낸 반면 학습 동기는 상대적으로 낮게 나타났다. 이에 본 연구는 엔지니어링 수업 모델을 적용한 로봇활용 STEM 융합교육 프로그램을 개발하였다. 프로그램의 주제는 4학년 과학교육과정의 한 단원이면서 학생들에게 친숙하고 로봇의 활용이 효과적인 '동물'로 정하였다. 로봇활용 STEM 프로그램은 로봇소양교육, 주제관련 교과학습, 엔지니어링 교육활동의 세 영역으로 구성되었다. 개발된 STEM 프로그램은 현장교사 14명으로부터 검토를 받았으며 연구결과 로봇 소양 유무에 상관없이 대부분의 교사가 프로그램의 목표, 내용 구성, 로봇의 활용에 대해 긍정적 반응을 나타내었다.

The purpose of this study was to develop and apply of career education program in science and engineering fields for science gifted high school students. To do this, the career education program was developed and applied to science gifted high school students 129 in H-science gifted high school with K-institute. The results are followings. First, after participating in the career education program, the career decision making self-efficacy of students were increased significantly. Second, it has been increased that external factor of career outcome expectation and continuation effort of grit. In this study, it has showed educational effects of the career education programs that related to career recognition in science and engineering fields for science gifted high school students by developing and applying of program. Based on these results, it is necessary to recognize the importance of customized career education programs for science gifted high school students.

본 연구에서는 공학계열 학생들이 인지한 학생 자신의 학습성과 달성도와 교수가 학생에게 부여한 학점간의 상관관계를 분석하고자 하였다. 서울 시내에 있는 두 개 대학의 공통된 4개 프로그램을 연구대상으로 하여 2006년도 1학기 말에 실시한 프로그램 학습성과 달성도 평가 결과와 해당 학기 학점 자료를 비교, 분석함으로써 학생들의 자기평가와 교수의 학생평가간의 관계를 알아보았다. 또한 그 분석 결과를 토대로 하여 공학교육인증 제도의 운영, 특히 학습성과 달성도 평가 방법에 관한 개선책을 제안해 보았다.

The skill that meets the intellectual and technical requirements in workplace is called hard skill. The counter part of it is 'softskills' which enhances an individual's interactions, job performance and career prospects. It becomes more necessary skill as society changes. In this paper we first show the demand for the softskill improvement education for engineering major students. Then we introduce a 'softskill improvement education' program developed by the "Center for innovative engineering education" in a University. The contents of the program are chosen by the needs of society, companies that hire our students, ABEEK educational objectives and consulting from professors. To improve the skills we used various activities as tools which are mentioned and introduced. The evaluation of the program results are discussed. We suggest some ways to improve the program.

Nonlinear energy operator(NEO) is usually used to estimate energy content of linear oscillator. We applied the modified nonlinear energy operator (MNEO) to detect R-peak of ECG and analyzed variation of R-R interval during sleep with nonlinear methods, piecewise correlation dimension and approximate entropy (ApEn) which estimate complexity of time series. ApEn applied to R-R interval reveals trends as sleep state changes.

In this paper, we present a wearable measurement system for monitoring rounded shoulders. The system contains a shoulder correction band and a stretch sensor that can correct and measure shoulder posture, respectively. The capacitance of the stretch sensor changes linearly according to changes in the shoulders. To verify measurement, a motion analysis system was used as the reference to compare the change in the rounded angles of the shoulders and the change in the stretch sensor's capacitance. The results indicated that there is a high correlation between the two changes and the system can be used as a monitoring device for rounded shoulders.
