Human error is an important cause of maritime accidents and the identification of human error is fundamental to maritime-accident preventions. In particular, the pattern of technical behavior taken in the circumstance of bridge teams(navigator & helmsman) provides important information to identify human error. The purpose of this study is to identify and analyze technical behavior pattern of bridge teams using Williamson's turn for rescue of persons overboard. The focus of this study is to build and analyze a cognitive model of the human behavior factors of the bridge teams in the process of implementing the experiments. The experimental environment was constructed using a ship-handling simulator and conducted an experiment on participants from 24 bridge teams. As a result of the experiment, it was able to identify the behavior pattern of the ship's maneuvering and maintain trajectory using the rudder and engine. This study is expected to correct human error in the bridge teams application to the certification and training of seafarers.

Knowledge management is an innovation paradigm to improve organizations competitiveness by strengthening organization's knowledge competency. Most organizations which have implemented knowledge management have experienced various difficulties in improving organization's knowledge competency, and so they have strived to find solutions. For the problems, it may be considered as an effective approach to link between knowledge management and human resource development. This study introduces two real cases adopting such approach focusing on competency development and career development which are primary areas of human resource development, and presents a model structuring core mechanisms which can be found in the cases. The model focuses on creating synergy effects between knowledge management and workforces' competency development. The cases and the model are expected to be helpful in enhancing organizational competency and the performance of knowledge management.

Since emergency response training for maritime safety and safety education of maritime education institutions are conducted based on the set scenarios and education contents, there are limitations in the reduction of human error and response to various situations. Although there is a need for improvement, there is no way to improve response capabilities by assessing existing education training and securing diversity in situations. This study proposes a theoretical procedure analyzer method to model the diversity of situations for the improvement of emergency response training. This paper defines the human and system theoretical procedure analysis model (HSTPA) based on the organic relationship of the source and system. The limitations of the existing training were derived by analyzing the errors that each component could produce and applying them to the fire response training scenarios requiring vertical reporting systems and responses. The segmentation and inspection of training scenario considerations applying the proposed HSTPA model is believed to help create diverse and realistic scenarios in emergency response training and education, and improve the situation judgment understanding and response capabilities of the subjects.

Agile software development methodology is a lightweight software development method, plays an important role in the software development team. In this paper, we propose programs that in when agile development co-operation, team management, team collaboration and project management tasks can be high efficiency and allocation of human resources. The proposed model, the use of 6-Sigma priority assignment, established a mathematical model of the operation and distribution of human resources is the most reasonable people go to work. Cooperation makes team-based agile development can improve efficiency. This method improve staff efficiency by teamwork to improve the productivity of software development.

Although previous studies show that organizational culture and organizational communication could be influential factors in knowledge management and organizational performance, the more integrated research to indicate relationships among all of the factors is still needed. By indicating the inter-relationships among the factors and the direction of the influence, this paper suggests various ways to develop an integrated approach to the improvement of organizational performance through knowledge management and other related factors. Thus, the purpose of this study is to investigate the relationships among national culture, organizational culture, organizational communication, knowledge management, and organizational performance. Based on a comprehensive review of extant literature on the relationships among these factors, the relationships are summarized in the conceptual model. According to the model, organizational performance is influenced by knowledge management, organizational communication, and organizational culture, and knowledge management is influenced by organizational communication and organizational culture. Based on the conceptual model, implications for human resource (HR) researchers and practitioners seeking to optimally improve organizational performance are presented.

The prevention of marine accidents has been a important topic in marine society for long time, and various safety policies and countermeasures have been developed and applied to prevent those accidents. In spite of these efforts, however, significant marine accidents have taken place intermittently. Ship is being operated under a highly dynamic environments, and many factors are related with ship's collision, whose factors are interacting. So, the analysis on ship's collision causes are very important to prepare countermeasures which will ensure the safe navigation. This study analysed the ship's collision data over the past 10 years(1991-2000), which is compiled by Korea Marine Accidents Inquiry Agency. The analysis confirmed that‘ship's collision’is occurred most frequently and the cause is closely related with human factor. The main purpose of this study is to analyse human factor. For this, the structure of human factor is analysed by the questionnaire methodology. Marine experts were surveyed based on major elements that were extracted from the human factor affecting to ship's collision. FSM has been widely adopted in modeling a dynamic system which is composed of human factors. Then, the structure analysis on the causes of ship's collision using FSM are performed. This structure model could be used in understanding and verifying the procedure of real ship's collision. Furthermore it could be used as the model to prevent ship's collision and reduce marine accidents.

This study investigated the purpose of commissioned on-board training and the legal basis for the management of commissioned on-board trainees, focusing on the seafarer educational institution belonging to the Ministry of Education, which cultivates merchant mariners. A program was developed based on this research. Despite the legal basis for the management of commissioned on-board trainees, satisfaction with on-board training management has not been high, and the on-board trainee management system of the university was poor. As a result safety accidents among commissioned on-board trainees occurred on ships, and a few students abandoned on-board training. An I.M.S.A.R. model has been developed for safe and systematic management of commissioned on-board trainees, and a base for a human resource management program for commissioned on-board trainees has also been developed. This study is meaningful in that it derived a practical plan for the management of commissioned on-board trainees.

Human resources are one of the most essential elements of an organization. In particular, the more closed a group is, the higher the value each member has. Previous studies have focused on personal attributes of individual, such as medical history, and have depended upon self-diagnosis to manage structures. However, this method has weak points, such as the timeconsuming process required, the potential for concealment, and non-disclosure of participants' mental states, as this method depends on self-diagnosis through extensive questionnaires or interviews, which is solved in an interactive way. It also suffers from another problem in that relations among people are difficult to express. In this paper, we propose a multi-faced diagnosis model based on social network analysis which overcomes former weaknesses. Our approach has the following steps : First, we reveal the states of those in a social network through 9 questions. Next, we diagnose the social network to find out specific individuals such as victims or leaders using the proposed algorithm. Experimental results demonstrated our model achieved 0.62 precision rate and identified specific people who are not revealed by the existing methods.
