업무프로세스 관리시스템(BPMS：business process management system)을 이용하면 새로운 프로세스를 정의하거나 기존의 프로세스를 갱신하는 일이 매우 용이하다. 대체로 표준화되고 일상적인 업무를 대상으로 프로세스를 관리하는 것은 이러한 소프트웨어를 사용하여 효율성을 높일 수 있겠으나, 비일상적인 예외상황에 대한 처리를 위해서는 별도의 전문가 참여나 특수한 의사결정 과정을 거쳐야 하는 경우가 많다. 본 논문은 다수의 예외처리용 업무 프로세스가 저장소에 축적된 상황을 전제로 예외처리 프로세스 선정의 자동화 방안을 제시한다. 예외처리에 가장 적합한 프로세스를 검색하는 것은 예외상황에 관한 충분한 이해가 필요하기 때문에 상황의 인지(context awareness)는 매우 중요한 과제이다. 예외상황의 이해를 원활히 하고, 예외처리 프로세스의 효율적인 선정을 위해 본 연구에서는 '상황변수'와 '의사결정변수' 자료구조를 도입하였다. 전자상거래의 배송과정의 예외사례를 사용하여 제시한 변수구조가 어떻게 검색트리 생성에 활용되는지를 예시하였다. C5.0 알고리즘은 최적검색트리를 생성해주며, 그것은 또한 문제의 상황에 최적인 예외처리 프로세스의 선정을 위한 검색경로를 설정한 것임을 보여준다.

Objective: The aim of this study is to model all levels of situation awareness (SA), which would be able to predict situation awareness quantitatively. Background: When measuring situation awareness, directly measuring SA methods such as SAGAT and SART have been utilized. Several approaches (cognitive modeling approaches) were introduced to model SA but level 3 SA was not completed. For real-life situation, however, it is necessary to detect the problematic level of SA rather than overall SA. Therefore, we proposed a new model of all levels of SA in this study. Method: In order to model all levels of SA, this study chose factors in ACT-R architecture through literature review. ATC (Air Traffic Control)-related simulation task was video-taped to analyze human behaviors in order to model all levels of SA including level 3. Results: As a result, regression analyses show that cognitive activities (neural activations) represented for all levels of SA were highly correlated with SAGAT. Conclusion: In conclusion, neural activations in ACT-R could be proved to be effective to model all levels of SA. Application: Our SA model could be used to predict all levels of SA quantitatively without directly measuring the SA of operators.

For prediction of ground movement per the excavation step, observational results of ground movement during the construction was very different with prediction during the analysis of design. step because of the uncertainty of the numerical analysis modelling, the soil parameter, and the condition of a construction field, etc. however accuratly numerical analysis method was applied. Therefore, the management system through the construction field measurement should be achieved for grasping the situation during the excavation. Until present, the measurement system restricted by ‘Absolute Value Management system’only analyzing the stability of present step was executed. So, it was difficult situation to expect the prediction of ground movement for the next excavation step. In this situation, it was developed that ‘The Management system TOMAS-EXCAV’ consisted of ‘Absolute value management system’ analyzing the stability of present step and ‘Prediction management system’ expecting the ground movement of next excavation step and analyzing the stability of next excavation step by‘Back Analysis’. TOMAS-EXCAV could be applied to all uncertainty of earth retaining structures analysis by connecting ‘Forward analysis program’ and ‘Back analysis program’ and optimizing the main design variables using SQP-MMFD optimization method through measurement results. The application of TOMAS-EXCAV was confirmed that verifed the three earth retaing construction field by back analysis.

Examples and experiences of risk management on radiation under prolonged exposure situation are shown. The accident of the Fukushima dai-ichi nuclear power plant after the great east Japan earthquake (11 March, 2011) elevates background level of environmental radiation around the east Japan. For example, ambient dose equivalent rate around Tohkatsu area next to Tokyo located about 200 km-south from the plant, is about 0.1-0.6 micro-Sv $h^{-1}$ mainly due to $^{134}Cs$ and $^{137}Cs$ falling on the ground soil. This level is about double or up to ten times higher than the genuine natural level around the area. International Commission on Radiological Protection (ICRP) recommends how to face the existing exposure situation; that is the prolonged exposure situation. Referring to ICRP's reports and/or related international/domestic documents, we have been discussing and acting to gain public's safety and relief, who have a possibility to be exposed to prolonged lower-dose radiation. Here, we introduce our several experiences on risk management, especially focusing on risk communication, radiation education to public, and stakeholder involvements into making decision in local governments on radiation protection, relating to the accident.

Since the mankind started its space mission, the number of artificial space objects has been increasing exponentially. It contains not just the space machines which are in use but the machines which are out of order. Meantime, those dead machines are being a serious danger, a real threat to human's lives and property because of it could re-enter into the earth's atmosphere and fall to the ground causing mega-disaster. As the number of space activities gets growing so far, the re-entry of the space objects will be a lot more happened in the future. Therefore, not just natural space object like asteroids but the artificial space object like artificial satellite and space station can cause the disaster by falling to the ground. To protect our nation and our property, the government has set up the space disaster management center in Korea astronomy and Space science Institute. In this study, we surveyed public's recognition of the space object's re-entry situation and analyzed it to contribute building national space disaster management policy.

Whenever a disaster occurs, people emphasizes that "Safety management is most important thing in the company". However, a situation of safety management is not changed dramatically after accidents in the past. Many small-and-medium sized industries neglect the importance of safety management. Current situation can be easily figured out when looks up an occurrence rate of accident, accident frequency rate and intensity rate. This paper investigated what workers of hotel-related industries think of a safety and types of accidents, effect of a safety education. On-site-survey was conducted for actual workers in four deluxe hotels and one condominium. 207 persons out of 400 people were replied. Statistical analysis was performed with SAS package about their reply. In injured type, cut from knife was most frequent. Main cause of accident was a unsafe posture and a unsafe behavior, so more safety education for these workers are necessary. In a physical pain which related with job, chronical pain was most dominant. As a result, a safety education has a high correlation with an experience of injured and treatment of safety, Cooking department has highest occurrence of accident than any other departments. Workers with an experience of five to ten years have most lowest treatment of safety, aid of safety education, safety feeling of their working environment, so peer attention must be put on these people to reduce accidents.accidents.
