Currently, the Korean railway safety law (RSL) and its ordinances have been enforced for the guarantee of the safety of railway. In RSL, the quality certification is required to guarantee the safety and performance of railway components or systems. However, not much attention has been focused on the quality certification scheme for railway components or systems since the scheme is relatively new. Therefore, in this investigation, the detailed guidelines and main contents for the enforcement of quality certification for railway components will be suggested, and the detailed items including the procedures, subjects, management, etc., will be addressed. Moreover, a better understanding on quality certification for railway components will be provided.

This study focuses on the benefit-cost analysis of certification of more than eight hundred devices and equipments used primarily in farm work. Specifically, EPA-suggested averting behavior approach was used for the analysis. Cost-benefit analysis indicates that there will be a net cost of 30 billion won for the first year since the introduction of the certification system. It is expected, however, that net benefit of 568 billion won after 11 years and the accumulated net benefit will reach to 3,867 billion won. These results validate the introduction of safety certification systems for devices and equipments used in farm work sites.

This study suggests systematic procedures to improve safety policies on prevention of industrial accidents associated with industrial machines and devices. Specifically, new method of cause analysis of industrial accidents associated with industrial machines and devices is suggested and the related accident data are re-analyzed. Effectiveness of direct safety regulations such as safety certification, self-declaration of conformity, safety device regulation and safety inspection of industrial machines and devices are also analyzed. Based on those analysis results, transition from the current user-oriented safety device regulation to more balanced direct regulations on both manufacturer and user is suggested. Together with severity and frequency of industrial accidents, unit severity and unit frequency need to be taken into account to further assess the risk associated with a particular industrial machine or device. Balance between safety regulations will be realized by proper adjustment of lists of safety certification and inspection, and certification and inspection standards. This will also guarantee the maximum benefit over cost in such safety regulations.

The aim of this study was to analyze pilots' safety consciousness and grit level, and the correlations between them. Participants were 142 pilots for pilot qualification (n=78), certification 1 (n=12), and 2 (n=52) level. The data were gathered from questionnaire for safety consciousness and grit scale from April to August 2022. Statistical treatment were processed (by SPSS 21.0 for windows) by descriptive analysis for all variables. One-way ANOVA was processed for analyze pilots' safety consciousness and grit scale by their groups. And the correlations were analyzed for investigating relations between them. Statistical significancy was set as p<.05. The results were as follows. First, pilots' safety consciousness showed higher trend in certification 1, qualification and certification 2 as considerable. The grit scale showed higher trend in qualification, certification 2 and 1 in order. The grit and its subfactor passion showed significance (p<.05). Second, the correlations among factors showed significance(p<.05). Conclusionly, safety consciousness was importantly recognized to the certification 1(F-4/5) pilots and grit to qualification pilots. The limit of this research was in small sample size, although need further study for practical using.

항공기에 사용되는 복합소재는 항공기의 감항성 확보를 위하여 인증된 소재를 사용해야 하며 소재의 물리적 특성 및 공정을 확인하여 재료규격 및 공정규격서등의 인증 문서와 시스템을 승인하는 방식으로 인증이 진행된다. 국내 복합소재 인증시스템은 국토교통부의 항공기용 복합재료 시범인증 사업을 통해 마련되었으며 현재 항공기 전문검사기관인 항공안전기술원에서 인증 및 공유 데이터시스템을 구축하여 운영하고 있다. 본 논문은 실증을 바탕으로 구축된 항공기용 복합소재 인증체계의 개선사항을 식별하고 이에 대한 개선 방안 도출을 통해 국산 항공기용 복합소재의 인증 및 산업 활성화 방안을 제시하였다.

Softwares in railway system are being used in the area of railway control system, directly associated to safety. Because the instinct characteristic of Software is uncertainty, Software development without safety insurance is very hazardous situation. In order to derive safety certification process in the railway system, certification and approval processes in the nuclear, aviation, and military area are studied. Software quality should be improved by two aspects : one is product aspect, another is process aspect. GS(Good Software) and ES(Excellent Software) certification can be exemplified in a product aspect approach. In those process certification, CMMI (Capability Maturity Model Integration) or SPICE (Software Process Improvement and Capability dEtermination : ISO/IEC15504) is being used as models for assessing process maturity of organization. Following the studies, safety management procedure in the railway system is suggested.
