새로운 시스템이나 제품이 철도운영환경에서 이용할 수 있을 만큼 안전하다는 것은 체계적인 문서화를 통해 입증해야 한다. 이러한 적정성을 제공하기 위해서는 안전성 관련 사항들은 논의에 대한 유효성을 판단하기에 앞서 독립적인 검증기관이나 자체적인 전문 평가를 수행하는 기관(또는 관리기관)에 제시되어져야 한다. 이러한 유효성은 종합안전대책기술서 형태로 제공되어지며 이는 사실에 대한 단순한 열거가 아니라 해당 시스템이나 제품의 실제 사용시 안전하다는 확신을 해당 기관에게 줄 수 있도록 고안되어 있는 일련의 논의들이다. 종합안전대책기술서는 관계자가 시스템 및 제품의 신규도입으로부터 발생되는 모든 리스크에 대한 분석 및 평가 수행여부와 이러한 리스크를 어떻게 관리하고 개선시켜 왔는지를 나타내주는 문서이다. 또한 관리가 효과적이고 지속적으로 적용되었음을 확인하기 위한 관리시스템을 제시해 주기도 한다. 본 연구는 유럽의 철도산업 범주내에서 종합안전대책기술서 그 자체의 특성과 시스템의 형태 및 적용 가능한 제품에 대해 정의를 내리는데 그 목적이 있으며 기술서의 취지와 구조, 보조문서 및 관련법규에 관한 사항에 초점을 맞출 것이다.

In this work, risks in EPC project for overseas power plant projects are analyzed and risk management methods are suggested to reduce cost and to shorten time. 79% of risks occurred in the engineering phase for S project located in South-East Asia. The impact scales of risks on major project objectives which are cost, time, scope, and quality are analyzed as 3.5, 3.8, 2.7, and 3.7, respectively. The level of impact scales is very similar to each other except the impact scale of scope. The risk management methods suggested in this study have to be applied at the appropriate time to manage risks effectively. After that, risks are managed continuously by monitoring.

Recently, domestic construction companies have been moving towards overseas markets due to decreasing orders and an increase in competitiveness within the domestic market. However, there is a higher risk involved in the overseas construction Industry than in the domestic construction industry. Especially, because domestic construction companies lack development's experience, such a companies have a weakness of hidden risk factors. For Overseas New Town development project's success of domestic construction companies, preferentially, It Is necessary to deduce and analysis of risk factors in real estate development phases. This study would possibly be able to provide the preliminary data for Overseas New Town development projects in the future.

Although the depression of oversea construction market becomes more serious recent years, asian construction market is relatively dynamic, particularly in china. However, few research has been conducted about how to manage construction projects in china as foreign developers. Four important risks are identified from series of surveys using the WBS-RBS method, the result shows that the main risk of tender stage is 'Tender max price error', ' Bill of quantities error', 'Unusual low price' and 'Moral risk' respectively.

As the construction industry has been increasingly complex, aging workers, hard-working avoiding young generation, foreign workers having language problem for the past decades, delivering of construction qualified workers has been a rising problem. This misalignment between the complex jobs and the number of skilled workers will continue to be in issue that the construction industry will face for following decades. Construction field workers who are working outside in uncontrollable condition unlike manufacturing industry are exposed to easily construction safety accident. There are so many efforts to prevent and control the construction accident. However, the relationships between the construction works and construction safety accident has not been well dealt and investigated based on objective accident data except for the qualitative study through interview, delphi and so on. Therefore this study analyzes job risk matrix exposed to safety accidents based on statistic data for 20 years from Korean Occupational Safety & Health Agency in order to prevent the construction field accidents.

Quality control and safety represent increasingly important concerns for project managers. In the worst case, failures may cause personal injuries or fatalities. Accidents during the construction process can similarly result in personal injuries and large costs. We present the results of a study designed to identify the tools that are most widely used and those that are associated with successful project management in general, and with effective project risk management in particular. The study is based on a questionnaire administered to a sample of project managers from construction enterprises. The response data was analyzed in order to find which tools are more likely to be used in the those organizations that report better project management performance and in those that value the contribution of risk management processes.

Recently, the dramatical increasement of personal information infringement makes the government strongly enforce the laws. The Key-point of law enforcement is the DB encryption. Nevertheless, DB encryption is the one of the hardest thing in the organization's security measures. The purpose of this paper is suggesting alternative means of residence numbers and showing the possibility of indicator usage for safety measures. This research suggested the best ways to make a decision through a before and after comparison of the DB encryption cost of the inherent identification number elimination in "Social Welfare consolidation service system". When this research result was applied in "Happiness-e-Um system", we found that the alternative means are more efficient than the residence number for encryption cost, system revision time and so on.

In Korea, in the case of fire scenarios in performance design, it is assumed that the sprinkler is not working. In addition, it does not applicate various fire conditions. Therefore it is not enough that the accuracy about fire scenario. In foreign countries, reseach is being conducted to predict the casualities that can occur due to fire in the building space through statistical risk analysis. Also, research is consistently conducting for design that consider the sprinker probability of operation. Therefore, to analyze the fire risk of each building in Korea, the risk was analyzed using statistical data. As a result, the risk of casualties that can occur for each building use was analyzed as 0.6(persons/cases) for residential buildings, 0.25(persons/cases) for sales facilities, and 0.12(persons/cases) for buisiness facilities.

In the design and maintenance of buildings, identifying the degree of damage in the event of a fire is an important factor in fire prevention and fire safety design. In order to predict fire damage, safety measures should be established by predicting the nature of evacuation according to fire, smoke and in-house characteristics, and the effects of the operation of fire safety facilities should also be considered, but in Korea, the risk analysis due to the operation of fire safety facilities is insufficient. Accordingly, this study uses fire statistics and sprinkler inspection data to analyze the degree of fire damage caused by the operation of sprinkler facilities in a probabilistic manner.
