In recent years, there has been a rapid and wide spread of robot system in our lives and with the ever increasing the requirement of user for robot functionality, the software component is increasingly sophisticated and complicated. Accordingly it is inevitable to employ a standardized software platform. The OPRoS is open standard software platform based on component for robot system. When the software components were developed, it has got to validate the conformity of robot software components which comply with the OPRoS standard specification. In this paper, we deal with the design and implementation of the structural conformance test suite to verify and validate the conformance of components to be developed by user. As the results of some experiments, we could verify it from this test suite whether the components satisfied standard requirement or not.

This paper is a part of research series for the verification of the proposed Moon/Lim design equation. An analytical study was performed to examine the relation between the flexural behavior and the unbonded tendon stress of PSC members. The strain compatibility assumption was used in this study since previous studies showed that the stress variations of tendon had a close relation with the member displacements. The proposed equation has been developed with the same assumption of strain compatibility. Therefore the analytical procedure with the strain compatibility assumption was developed to compute the member displacements of previous tests. Then the analytical results were compared with tests results. The comparison showed that the strain compatibility assumption can be properly applicable to the design equation. Based on the analytical results, the relation between the tendon stress and the member flexural behavior at ultimate was examined. A parametric study also carried out with regard to the member displacements. As results, the parameters used for the proposed equation were proven to be proper for the computation of tendon stress.

The purpose of this study is to develop a training program for teachers to improve their entrepreneurial education competency for teenager entrepreneurship education. In order to achieve this objective, the training program was developed through a literature review and input from professionals. In addition, to verify field appropriateness of the entrepreneurship program for teachers, teachers participated in the program and a satisfaction survey was conducted. Results of this study are as follows. First, this study developed teaching contents and methods for entrepreneurship education which included 4 hours of online education and 26 hours of off-line education, for a total of 30 hours. Second, for verifying the applicability to schools and its effects, the satisfaction of training was examined using 88 teachers that participated in the entrepreneurship education program. Results found the satisfaction level was rated 4.58 for the curriculum suitability and 4.67 for the effectiveness of class contents, indicating that teachers were very satisfied with the training program and contents.

This study attempted to suggest a useful measurement method based on previous. For the empirical analysis of this study, based on the previous studies presented above, the effect of HRM strategy fit on leadership development execution was examined, and the mediating effect of the leadership development attitude of the owner-managers was verified. The questionnaire was set based on the questionnaire verified and used in previous studies, and for empirical analysis, 300 paper of the questionnaire were collected and the entire collected questionnaire was used for statistical analysis. As a result of analyzing the effect of HRM strategy fit on leadership development execution, it was verified to be statistically significant.

전자 신뢰 매커니즘 기반의 정보사회에서는 기밀성과 인증의 확보가 필수적이며 이를 위해서는 전자서명 기술을 포함하고 있는 공개키 기반의 인증서관리 체계의 확립이 선결되어야 한다. [3] 인증서의 정당성을 검증하기 위해 검증자는 소유자의 인증서와 그 인증서를 인증한 공인인증기관의 인증서를 검증해야 하고, 이전에 인증서 폐지를 확인해야 하며, 실제 공개키 기반구조 환경에서 인증서의 유효성을 검증하기 위해서는 인증서 자체 검사와 함께 최상위 인증기관(루트CA)으로부터 사용자에게 인증서를 발행한 단말CA까지의 인증트리를 검증해야 한다[3]. 본 연구에서는 효율적인 인증서 폐지정보의 검증을 위해 다중 CA환경에 적합한 NPKI상에 B-Tree데이터구조를 적용하는 인증서 폐지 검증 방안을 제안하고자 한다.

Practical and efficient application of lean construction, which has been proposed as an alternative to the limitations of traditional construction management methods, was developed to facilitate application on site and improve productivity through the fusion of traditional construction management methods. The concepts of Lean Time and Lean Cycle Time, which are the principles of lean construction, were introduced to eliminate waste and smooth flow production and pursuit of perfection, and the goal of establishing and improving the criteria for measurement and improvement was established and the information collection template was configured and applied to ensure reliability of measurement and analysis. Based on this, the project feasibility, reliability, and continuous improvement process were applied to the Field case to verify its effectiveness.

Electromagnetic compatibility(EMC) performance of the first Korea space launch vehicle(KSLV-I) should be ensured and verified in order to guarantee the normal operation among the spacecraft, ground facilities which are installed in the space center, and other wireless communication networks. For the purpose of the EMC performance verification, pertinent EMC test specifications, methods, and procedures for both the subsystems and the system should be established in consideration of operational properties and electromagnetic environmental effects. And it is required to maintain and control the EMC properties consistently in accordance with the determined specifications up to the program closing phase. In this paper, sequential management work conducted during the overall development process of the KSLV-I is explained, and not only the phased EMC test plan for each model of the KSLV-I and its subsystem but also test method, specification, and results of the verification tests are presented. And also, multipaction analysis results are presented.
