The objective of the study is to evaluate the effectiveness of Crew Resource Management (CRM) training program for operators in the Main Control Room (MCR) simulator of APR-1400 Nuclear Power Plant. The experiments were conducted for two different crews of operators performing six different emergency operating scenarios during four-week period. Each crew consisted of the five operators: senior reactor operator, safety technical advisor, reactor operator, turbine operator, and electric operator. All crews (Crew A and B) participated in the training program for the technical knowledge and skills which were required to operate the simulator of the MCR during the first week. To verify the effectiveness of the CRM training program; however, only Crew A was selected to attend the CRM training after the technical knowledge and skills training. The results of the experiments showed that the CRM training program improved the individual attitudes of Crew A significantly. Team skills of Crew A were found to be significantly better than those of Crew B. The CRM training did not have positive effects on enhancing the individual performance of Crew A; however, as compared to that of Crew B. Implication of these findings was discussed further in detail.

The Nuclear Power Plant(NPP) industry in Korea has been making efforts to reduce the human errors which have largely contributed to about 150 nuclear reactor trips since 2001. Recently, the Crew Resource Management(CRM) training has risen as an alternative countermeasure against the nuclear reactor trips caused by human errors. The effectiveness of CRM training in NPP industry, however, has not been proven to be significant yet. In this study a return on investment(ROI) model is developed to measure the effectiveness of CRM training for the operators in Korean NPP. The model consists of mathematical expressions including multiple variables affecting the CRM training impacts and nuclear reactor trips. Implication of the model is discussed further in detail.

In the era of the 4th industrial revolution, the aviation industry is also growing remarkably with the development of artificial intelligence and networks, so it is necessary to study a new concept of crew resource management (CRM), which is required in the process of operating state-of-the-art equipment. The automation system, which has been treated only as a tool, is changing its role as a decision-making agent with the development of artificial intelligence, and it is necessary to set clear standards for the role and responsibility in the safety-critical field. We present a new perspective on the automation system in the CRM program through the understanding of the autonomous system. In the future, autonomous system will develop as an agent for human pilots to cooperate, and accordingly, changes in role division and reorganization of regulations are required.

Organizational culture among flight crews has a profound impact on the individual attitude and behavior of member flight crews, and active training is conducted focusing on improving flight crews' Crew Resource Management(CRM) performance. However, adequate research and training on the relationships between flight crew's individual culture and CRM performance have not been conducted. Hence, this study examined the effect of individual cultural values on CRM performance and the moderation effect of psychological safety, with captains and first officers working for commercial airlines as participants. For the factors related to individual cultural value scale, power distance had no significant effect on CRM performance, uncertainty avoidance had a significant negative effect, and individualism had a significant positive effect. With regard to the moderation effect of psychological safety on the relationships between individual cultural values and CRM performance, a significant interaction was found between power distance and CRM performance, but not between uncertainty avoidance and CRM performance, or between individualism and CRM performance. Power distance and CRM performance exhibited a strong negative correlation in case of low psychological safety. Compared to existing research measuring the cultural characteristics of pilot groups on a national or organizational culture level, this study is uniquely valuable in that it also covers the relationship between individual cultural values of commercial airline flight crews and CRM performance.

LOSA(line operation safety audit)는 정상적인 운항 상태에서 운항 승무원이 발생할 수 있는 사고를 수집하기 위한 선제적 데이터 수집 방식으로 비행 중 발생하는 TEM(threat error management)과 CRM(crew resource management) 등을 수집하는 안전관리프로그램이다. 기존의 LOSA 기록 방식은 워크시트(worksheet) 에 관찰자가 직접 작성하여 자료를 보관하고 관리를 수행하였으나, 자료 보관의 어려움과 비밀 보장이 어려운 문제점이 있다. 기존의 LOSA 수집방식 대신 웹(web) 형태로 한국형 LOSA(K-LOSA)를 구현과 TEM 분류 코드를 변경하므로 효과적인 자료 관리 및 비밀 보장성을 확보하였다. 본 논문에서는 LOSA에 대하여 살펴보고 K-LOSA 프로그램의 구성을 소개한다.

The nuclear power industry in the world has recognized the importance of integrating non-technical and team skills training with the technical training given to its control room operators to reduce human errors since the Three Mile Island and Chernobyl accidents. The Nuclear power plant (NPP) industry in Korea has been also making efforts to reduce the human errors which largely have contributed to 120 nuclear reactor trips from the year 2001 to 2006. The Crew Resource Management (CRM) training was one of the efforts to reduce the human errors in the nuclear power industry. The CRM was developed as a response to new insights into the causes of aircraft accidents which followed from the introduction of flight recorders and cockpit voice recorders into modern jet aircraft. The CRM first became widely used in the commercial airline industry, but military aviation, shipboard crews, medical and surgical teams, offshore oil crews, and other high-consequence, high-risk, time-critical industry teams soon followed. This study aims to develop a CRM training program that helps to improve plant performance by reducing the number of reactor trips caused by the operators' errors in Korean NPP. The program is; firstly, based on the work we conducted to develop a human factors training from the applications to the Nuclear Power Plant; secondly, based on a number of guidelines from the current practicable literature; thirdly, focused on team skills, such as leadership, situational awareness, teamwork, and communication, which have been widely known to be critical for improving the operational performance and reducing human errors in Korean NPPs; lastly, similar to the event-based training approach that many researchers have applied in other domains: aircraft, medical operations, railroads, and offshore oilrigs. We conducted an experiment to test effectiveness of the CRM training program in a condition of simulated control room also. We found that the program made the operators' attitudes and behaviors be improved positively from the experimental results. The more implications of the finding were discussed further in detail.

민간 항공기에는 기장과 부기장이 반드시 탑승해야 한다. 일반적으로 기장은 항공기 운항 중 위난방지에 관한 역할과 책임을 이행하고, 부기장은 기장을 보좌하거나 조언하는 기능을 담당한다. 역사적으로 70%~80%의 항공기 사고가 조종사 인적요인에 의하여 발생함에 따라 전 세계적으로 CRM (crew resource management)이라는 운항관리기법을 도입하여 운영하고 있다. 한편 안전행동은 지식과 기술을 사용하여 위험으로부터 보호하려는 인간의 행동이며, 항공기 조종실에서 운항업무를 수행하는 기장과 부기장은 각각의 역할과 책임, 그리고 경험의 차이에 따라 안전행동의 수준 또한 다를 것으로 예상된다. 선행연구는 조종사의 안전행동이 기술적 능력에 영향을 받기보다 CRM skill과 같은 비기술적 요소에 영향을 받는다고 하였으며, 본 연구는 기장과 부기장의 CRM 역량 차이를 파악하고 그 차이가 안전행동과의 상관관계를 가지고 있는지를 검증하고자 수행되었다.

It has been focused on that the major reasons of aircraft accidents resulted not from human error but from the failure of teamwork or communication in 1980's. Such opinions were suggested in the workshop, so called, "Resource Management on the Flight Deck" by NASA in 1979. The researchers agreed the fact the source of human error was originated from the failure in teamwork, communication or even in leadership of captain. Due to the rapid development of aircraft technologies, the reasons for aircraft accident could be easily found out. According to the analysis results of the technology, most of reasons for the accident might directly be connected not to human error or stick-Rudder skill but to situational awareness, communication, leadership or decision making in the aircraft. This paper has tried to research empirically the satisfaction of flight crews who have gone thorugh CRM training in the commercial airline. Based on the quantitative scale by J. Ford et al. (2014), this paper has proved which characteristics of CRM training has a positive impact on the overall satisfaction of CRM training. It was proven that the teamwork and decision making programs among CRM training have a major effect to the satisfaction level of flight crews.

Flight safety in modern commercial aircraft depends on the ability of pilots to manage overall flight operations. ICAO has made it mandatory for airlines to adhere to Crew Resource Management(CRM) policies to reduce operational safety threats. CRM is a set of techniques designed to effectively manage the human resources, aircraft, and environmental factors in order to promote safety and enhance efficient air operations. When looking at the career backgrounds of new pilots joining the Republic of Korea's commercial airlines, discharged military fighter pilots represent the largest demographic. Fighter pilots are experienced in empowering leadership and directive leadership from their military training and culture. New commercial airline pilots with military fighter pilot training should effectively acquire the required civil aviation CRM skills. The present study has been carried out to determine how the leadership experience of this demographic affects the acquisition of CRM skills for commercial airlines, and it confirms that there is a positive correlation.
