Currently, in the course of introducing rolling stocks, RAMS standard and management by system engineering method apply to rolling stock system. Technical elements and results applied in system introduction phase are just used in acquisition stage, and these are not applied to the standard in railway site. Therefore, it is difficult to apply to standardized technology and quality assurance measure. Due to the establishment of the EU, railway operation system is internationalized and the international railway standards are being discussed in various ways. In addition, standardization is expanded from manufacture to operation and maintenance. It is to provide consistent standard in quality, cost calculation of maintenance technology, maintenance technology and quality assurance in case of international railway safety incidents. Therefore, this study is to find technology, quality and cost management model to be used for choosing railway-operation guidance by considering how technologies & quality have changed in system life cycle, compared with estimated standards, based on the technologies & quality-related result in the process of getting new rolling stocks and management guidance for operation & maintenance process.

As building heights increase, so do these challenges in Korea. High-rise buildings present a variety of challenges to fire safety and protection. The fire protection technology in our country is still on a weak situation which is mainly due to the lack of concerns by the government, companies and citizen. This paper provides general guidance regarding fire-related property protection system for high-rise building performance based design. The importance of high-rise building in of the number of occupants, the value of property, and the a catastrophic loss would have on the community all warrant an increased level of protection and life safety. Because, We have to prepare a new spacial code and standard guidance for fire protection at the stage of the high-rise building design.

It is important for universities to simply provide students with programs such as special lectures on employment, information on employment, mock interviews, and how to write self-introductions, as well as various information related to life planning and career and employment. However, life planning and career planning are also provided systematically. It is very important to provide. The purpose of this study is to analyze the effects of classes on life design and career felt by students through life planning and career classes and to suggest the direction of classes on life design and career. The research results are as follows. First, through life planning and career courses, college students had time to learn about themselves in the life planning part and developed reflective thinking about how they should live their lives. And it helped me plan for my four years of college. Second, in the career and job search section, it was helpful in finding a job and career path that suited me. I also realized that there are various occupations, and it was nice to be able to think about various things about employment. And it was seen as an opportunity to recognize the existence of various occupations. Third, in terms of class progress, the class progress including experiential activities and various invited lectures were good. He also said that he was interested in the class and was able to gain self-esteem through the class. Classes related to life planning and career guidance for college students provide students with opportunities to explore various career paths, so it is expected that many such classes will be held.

Bacillus subtilis 8 is highly efficient at degrading feather keratin. We observed integrated feather degradation over the course of 48 h in basic culture medium while studying the entire process with scanning electron microscopy. Large amounts of ammonia, sulfite, and $\text\tiny{L}$-cysteic acid were detected in the fermented liquid. In addition, four enzymes (gamma-glutamyltranspeptidase, peptidase T, serine protease, and cystathionine gamma-synthase) were identified that play an important role in this degradation pathway, all of which were verified with molecular cloning and prokaryotic expression. To the best of our knowledge, this report is the first to demonstrate that cystathionine gamma-synthase secreted by B. subtilis 8 is involved in the decomposition of feather keratin. This study provides new data characterizing the molecular mechanism of feather degradation by bacteria, as well as potential guidance for future industrial utilization of waste keratin.
