  • The newly updated Rail Safety Act is required to build a comprehensive railway safety management system with corresponding accreditation regulations for the purpose of safe railway operations. However, such efforts would not be enough to achieve a successful safety-performance solely without being in place of an appropriate level of safety cultures in an organization. No research was taken place to propose a safety culture maturity model and its estimate procedures in Korean railway industries. The research reviews a variety of safety maturity models applied in many other industries and the process of conducting surveys in order to propose a framework of railway safety maturity estimates, with a set of railway safety elements. This research is expected to contribute in diagnosing weak areas and finding their appropriate treatment, along with in placing the railway safety certificate program from 2014.

  • We reviewed foreign evaluation systems based on the macrobenthic and macroalgal communities and developed a system, composed of a set of ecological indices able to evaluate the functionality (FI, Functional Index; estimation of stability and productivity) and maturity (MI, Maturity Index; comparisons with biological parameters of natural reefs) of artificial reefs by comparing the status in the adjacent natural reefs in Korean coastal waters. The evaluation system was applied to natural and artificial reefs/reef-planned areas (natural reefs), established in the 5 marine ranching areas (Bangnyeong-Daechung, Yeonpyung, Taean, Seocheon and Buan) in the west coast of Korea. The FI ranged between 31.6 (Bangnyeong-Daechung) and 72.5% (Buan) and MI did between 53.1 (Seocheon) and 76.9% (Taean) in average. The evaluation of artificial reefs by the two indices, showed the most appropriate status in Taean. The FI between the adjacent artificial and natural reefs were in significant linear relationship (r2=0.83, p=0.01). This indicated the local status of biological community may be critical in determining the functionality of the artificial reefs. We have suggested an integrative but preliminary evaluation system of artificial reefs in this study. The output from the evaluation system may be utilized as a tool for environment/resource managers or policy makers, responsible for effective use of funds and decision making. Given the importance, we need to use the options to enhance and improve the accuracy as follows: (1) continuous validation of the evaluation system and rescaling the criteria of indicators, (2) vigorous utilization of observation and experience through the application and data accumulation and (3) development and testing of brand-new indicators.

  • 난황단백질인 비탈로제닌을 성숙한 암컷 붕어 혈청으로부터 음이온 교환 크로마토그래피를 이용하여 정제 하였다. 정제한 비탈로제닌을 BALB/c mice를 이용하여 폴리크로날 항체를 생산하였고 이를 protein A column을 사용하여 정제하였다. 또한 이렇게 정제된 폴리크로날 항체를 이용한 붕어 비탈로제닌 측정용 효소면역측정법을 개발하였으며 그 측정 범위는 2∼l,000ng/mL이고 recovery 변동 범위는 88∼112%였다. 또한 이 효소면역측정법을 평가하기 위해 성숙한 수컷 붕어를 1,000ng/L ethinylestradiol(EE2) 에 4주 동안 노출시켜 유도되어지는 비텔로제닌을 측정하였다. 그 결과 성숙한 수컷 붕어의 경우 비탈로제닌이 3주 만에 암컷 붕어의 평균수치만큼 유도됨을 알 수 있었다.

  • The purpose of this study is to verify the effects of R&D process maturity on product development performance and to verify whether R&D project performance mediating effect. The questionnaire was collected and analyzed to 131 persons related to the R&D work in 55 companies and public institutions performing R&D work. The results of this study are as follows, the effect of R&D process maturity on product development performance and mediating effect of R&D project performance were analyzed by simple and multiple regression analysis. Regression analysis was analyzed by SPSS statistical program. The higher the maturity level of the R&D process, the higher the product development performance and the R&D project performance, and the R&D project performance is partially mediated. It is concluded that it is important to establish and operate a systematic R&D process and to develop a project management methodology suitable for the characteristics of a company in order to improve product development performance. It is expected that if this study are utilized as practical R&D management methodology in corporate management, it will contribute to improvement of company product performance.

  • 본 연구에서는 청소년들을 대상으로 정의적 특성으로 분류해 온 도덕성의 성격과 발달 수준을 찾아 이를 기초하여 학생들의 자기 이해를 돕고 정의적 성숙을 가져올 수 있게 하는 자기 평가식 도덕성검사를 Kohlberg의 도덕성 발달 수준을 기반으로 한 온라인 도덕성 검사 시스템을 설계 및 구현하는 방법을 연구하였다. 구현된 시스템을 이용하여 학생들 스스로 자신의 도덕성을 진단하고 평가하여 자기중심성으로 부터 벗어나 협동과 상호존중의 관계를 지향할 수 있는 학생이 되도록 하는 것이 이 연구의 주요한 목적이다. 본 연구에서 설계하고 구현한 도덕성검사 시스템이 성공적으로 적용된다면 검사와 검사의 결과에 대한 진로안내가 한 시스템 내에서 이루어지기 때문에 학생들의 진로지도에 대한 효율적인 성과를 가져올 수 있을 것이며, 또한 쉽고 빠른 검사로 인해 지필검사를 통해 실시하는 것보다 훨씬 경제적인 효과를 올릴 수 있을 것이다.

  • Korean government has operated EA by the act on efficient introduction of information system and operation, etc. But the evaluation system for EA and the criteria don't prepare well. Particularly, There is no model for EA performance measurement and the way is insufficient. In this study, we derived 8 areas and 17 criteria for the performance evaluation based on the Performance Reference Model of U.S FEA and Korea. And we also derived 8 areas and 10 criteria for it based on the OMB EA Assessment Framework and the EA maturity model in Korea. We propose the performance evaluation model of the five areas that consists of the business performance, customer performance, process, human resource and the technology for EA performance evaluation. To verify the model, we applied the model to three organizations and evaluated EA performance. In addition, we compared the performance result with the performance evaluation area of EA maturity model of Korea to verify the result. We also analyzed the criteria of the proposed performance evaluation model with the current EA maturity model and Performance Reference Model of Korea. As a result of the evaluation, we verified of the proposed performance evaluation model, too.
