The e-navigation in IMO(International Maritime Organization) has been developed as a strategy for user oriented service followed by HEAP(Human Element Analysing Process) to assess the solutions in view of human ergonomics. Although IMO already had an interim guideline for human element assessment, it did not include appropriate human elements for user-oriented assessment, therefore there should be a need for revising the human elements of current guideline for ergonomic assessment of e-navigation. We have developed user-oriented human element checklist, threat elements caused by human external condition and error elements originated by human itself in line with the e-navigation development concept of user-based approach.

This study showed effective and new applicative direction of CRM of medical management after arranging CRM researches, measuring CRM activity and the results of medical institutions and clearing factors having an effect. In other words, 'Human Factors' variables and 'Physical Factors' variables have an effect on the result of CRM. 'Human Factors' variables have an effect on the qualitative result and 'Physical Factors' variables have an effect on the quantitative performance. In more strategic CRM continuum, Human Factors have a significant effect on the whole performance of CRM. And in more tactical, CRM continuum Human Factors and Physical Factors have significant effect on the whole performance of CRM. Consequently, The key point is grasp of what characteristics exist in CRM between strategic level and tactical level. This provides the foundation for the variables in marketing practice.

The purpose of this study was to investigate the causes of collisions by examining 668 cases of merchant ship collision accidents that occurred during the past 12 years (2010-2021) and analyzed them statistically. Further, the analysis results were applied to propose a human error prevention collision avoidance (HEPCA) model. The statistical annual report of the Korea Maritime Safety Tribunal (KMST) and the collision investigation report were investigated to collect data on the causes of collisions of merchant ships, and frequency analysis was performed using the statistical analysis tool, SPSS Statistics. In the first-stage analysis, the causes of collisions were analyzed targeting 668 merchant ship collision accidents, and in the second-stage analysis, the identified maximum frequency cause factors were analyzed in detail. The analysis results identified that 98 % of the cause of the collision was the human error of the navigator, and the highest frequency was in the order of neglect of look-out > violation of navigation regulations > improper maneuvering. The cause of the neglect of look-out was mainly neglecting continuous monitoring after the first recognition of the target ship. The HEPCA model for human error prevention was proposed by applying the analysis results to the collision case of the investigation report. The results of this study are expected to be used as educational materials at marine navigator educational institutions and in practice for avoiding collisions caused by human errors of navigators.

In this paper, we propose a API Gateway technique for the expansion of human resource management module, one of the ERP functions. The institution has introduced ERP (Enterprise Resource Planning) based on its efforts to transform all human and physical resources into business competitiveness and its response to the digital knowledge informatization environment, and listed it as multiple success factors. Human resource management is one of the factors that have been dealt with. However, ERP's Human Resources Management Module remains in the role of functional personnel management. How to utilize human resources begins with navigating and recognizing human resources. The proposed API Gateway technique leverages blockchain networks to design and implement APIs for human resource sharing and navigation, including the possibility of extending ERP's human resource management module. Secondly, it was designed and implemented using a smart contract that behaves like an API for preventing information forgery. The proposed method will not only be used as a tool that can actively utilize human resources, but will also be a complete resource for utilizing big data technology.

To reduce conducted a survey on human error risk factors and related experience frequency to drivers of Seoulmetro and Korail. The human error arising from systems operating urban railway aimed at eliminating and reducing the fundamental causes of urban rail accidents is based on research from a factorial point of view, since it contains problems dealing with the types and situations of accident generation. It is required to contribute to reducing human error so that urban railway accidents may be reduced and safe operation will be continuedly seared.

외부이물질에 의한 손상(FOD)으로 인해 항공기 및 엔진 등의 원상복구를 위한 비용손실 뿐만 아니라 항공기 안전운항에 큰 위협요인으로 부각되고 있다. 그러나 우리나라 FOD와 관련 된 연구 실태는 엔진부품, 타이어, 기체 및 조류충돌에 의한 사건사고에 대한 통계분석 등이 주를 이루고 있으며, 잠재적으로 FOD를 유발할 수 있는 항공기를 정비하고 취급하는 정비사 및 지상 조업직원 등의 인적요인을 고려한 연구는 전무한 실정이다. 이에 본 연구에서는 FOD의 정의와 발생 원인들을 살펴보고, 항공정비사를 비롯한 지상 조업직원들의 인적요인에 의한 FOD 유발가능성 등을 연구하여 FOD방지를 위한 개선 방안을 제시하고자 한다.

Expresway traffic accident is fatal accident by high speed, especially human injury is a great social issue. This paper aims to identify characteristic differences of highway accidents that involve human injuries or not. To analysis the elements that affect the two types of accidents used the logistic regression model. The analysis showed that human injury accident rate is increased in case of straight road, flat, or cut-slope areas, barriers, male driver, and older driver. These results provide the ground for actions to counter the problems. By discovering factors for accidents leading to fatality, this study can provide important implications for authorities that establish highway safety measures and policies in preventing human injuries or deaths from car accidents.

The development and operation of the MASS (Maritime Autonomous Surface Ship) is being actively discussed for more efficient and safer maritime transportation solutions. The autonomous navigation technology has positive aspects such as the prevention of marine accidents, improvement of fuel efficiency of ships and cost reduction, and negative aspects such as job loss, task change, and security problems. It is expected that there will be new human element issues such as the situation awareness of remote operators, because the shore-based control will be conducted when fully autonomous ships are in operation. In this paper, we consider major human element issues that should be factored in the development and operation of MASS, and suggest a method of HRA (Human Reliability Analysis) for P IFs (Performance Influencing Factors) of the remote operators that are expected according to the shore-based control.

This study was conducted to investigate the effect of strategic human resource management on job stress and occupational commitment of security workers. A sample of 188 persons was extracted using the SPSS 18.0 program as a significant sampling method for the security worker. Frequency analysis, correlation analysis, and multiple regression analysis were conducted according to the purpose of the data, and the following conclusions were drawn. First, strategic human resource management has a significant effect on job stress. Second, strategic human resource management has a significant impact on occupation. Third, job stress had a significant effect on occupation commitment. That is, two factors of strategic human resource management and job stress play a decisive role in occupation commitment, and job stress plays an important role as a parameter. In conclusion, if we select the factors of strategic human resource management needed for each organization and develop new methods and competitiveness, it will be very helpful for qualitative growth of security industry.

Around 70% of domestic aircraft accidents in helicopter aircraft. The causal factors of the helicopter accidents are identified as human factors. People have focused mostly on unsafe acts to prevent the accident. The accidents should be analysed on human factors to reduce accident. The unsafe acts can be managed effectively if the latent failures were identified through the HFACS. This paper is to introduce about the latent failure classified by the HFACS and provide the analysis regarding the latent failure of the helicopters by the aviation safety advisors through the interviews.
