Studies on the ship's automatic navigation & berthing control have been continued by way of solving the ship's mathematical model but the results of such studies have not reached to our satisfactory level due to its non-linear characteristics ar low speed. In this paper the authors propose a new berthing control system which can evaluate as closely as captain's decision-making by using the FNN(Fuzzy Neural Network) controller which can simulate captain's decision-making by using the FNN(Fuzzy neural Network) controller which can simulate captain's knowledge. This berthing controller consists of the navigation subsystem FNN controller and the berthing subsystem FNN controller. The learning data are drawn from Ship Handling Simulator (NavSim NMS90 MK III) and represent the ship motion characteristics internally According to learning procedure both FNN controllers can tune membership functions and identify fuzzy control rules automatically The verified results show the FNN controllers effective to incorporate captain's knowledge and experience of berthing.

Civil aircraft must have captain and first officer. In general, the captain fulfills his role and responsibility for preventing danger during aircraft operation, and the first officer is in charge of assisting the captain. Historicclay, as 70% to 80% of aircraft accidents have been caused by pilot human factors, crew resource management (CRM)has been introduced and operated worldwide. On the other hand, safety behavior is a human behavior to protect from danger using knowledge and skills, and the captain and the first officer who perform operations in the aircraft's cockpit are expected to have different levels of safety behavior according to differences in competence, responsibility, and experience. Preceding studies have shown that pilots' safety behavior is influenced by non-technical factors such as CRM Skills rather than technical ability, and this study was conducted to identify differences in CRM competencies between captain and first officer and to verify whether the differences are correlated with safety behavior.

The purpose of this study was to investigate the influence of the soccer team captain's empowerment on role perception and team cohesion. In order to achieve the purpose of the study, data of 154 students from elementary and middle school soccer teams and soccer clubs in Busan Metropolitan City and Gyeongsangnam-do were collected, and then exploratory factor analysis, Cronbach's α coefficient calculation and correlation using SPSS statistic 25.0 The reliability and validity of the relationship analysis and research tools were verified. After that, the results of multiple regression analysis for hypothesis testing are as follows. First, it was found that the empowerment of the captain of the soccer team had a partial positive effect on role perception. Second, it was found that the empowerment of the captain of the soccer team had a partial positive effect on the team cohesion. Third, it was found that the role perception of the captain of the soccer team had a positive effect on the team cohesion. Therefore, it is necessary to enhance the team's role and team cohesion through the empowerment of the captain of the soccer team.

On the general fishing boat in the same person of the fishing Chief and the Captain, the fishing chief positions are not separately. In this case, in Civil, Criminal and Administrative law, does not cause any problems. Just he take only responsibility for the legal effect of each, this is a natural solution for the effects of laws. But, if make one work unit, the fishing chief take fishing work from the position of the dominant of the captain, and moreover throughout the voyage work commands the captain. Such fishing chief center structure have roots institutive. In the case, according to legal liability by presenting solutions to the problem are as follows : firstly, The legal division Of the Sailing courses and operation course are necessary. Secondly, In the adminstrative ship official law, obligatory acquisition of the fishing Chief marine engineer qualification is necessary.

Studies on the ship's automatic navigation & berthing control have been continued by way of solving the ship's mathematical model, but the results of such studies have not reached to our satisfactory level due to its non-linear characteristics at low speed. In this paper, the authors propose a new control system which can evaluate as closely as captain's decision-making by using the FNN(Fuzzy Neural Network) controller which can simulate captain's knowledge. This controller contains the concept of safety according to channel width. The learning data are drawn from ship Handling simulator(NavSim NMS-90 MK III) and represent the ship motion characteristics internally. According to learning procedure, the FNN controller can tune membership functions and identify fuzzy control rules automatically. The verified results show that the FNN controller is effective to incorporate captain's knowledge and experience of manoeuvrability in channel.

This study tried to propose plan to prevent human error of railroad driver among human error of railroad worker which takes great share in railroad accident. For this, in order to maintain correlation between the accident actually occurred after the opening of high-speed railroad and experience of accident that did not happened, survey on respondent was analyzed by conducting survey on KTX captain who is working in driving work of high-speed railroad, and instruction management team manager who manages KTX captain and captain. This thesis classified the factors by human factor, job factor, environment factor, organization factor, and established human error management model by comparing and analyzing how each factors have spatial interrelations with a railroad accident. The purpose of this study is to contribute to make safe railroad, and reliable railroad by preventing human error accident by minimizing human error of high-speed railroad drivers, and improving driving workers to cope accurately and fast with irregularities through various institutional improvement, improvement of driving facilities, improvement of operating room environment, and improvement of education system.

Chapter 1 and 2 of this study examined the methodology of modern storytelling using the hero narrative structure. This involved analyses of Joseph Campbell's monomyth structure, which is the prototype model of modern storytelling and Christopher Vogler's story structure in which the monomyth structure is classified into 3 Acts and 12 Stages. In addition, the movie 'Captain America' was analyzed based on Vogler's narrative structure theory. According to the analyses results, the hero of 'Captain America' fully follows Christopher Vogler's hero narrative structure but in some cases, he does not follow the existing hero narrative structure. It is interpreted that this is because heroes of modern tales have different birth backgrounds from mythical heroes. There is also a difference even in the stage where a hero completes all adventures and returns home between modern tales and myths due to different social backgrounds. Therefore, these findings provide a basis for modification and supplementation of a modern hero epic. Through this analysis, the modified modern hero narrative structure is evaluated to be appropriate as a basic model for modern storytelling. Further, it is expected that those who frame a film script can complete a new hero epic while following the structure of syntagmatic systems by selecting a level among Northrop Frye's paragmatic systems based on this structure and considering story themes and heroes' personality and characteristics.

The wound healing activity of plumbagin and the chloroform extract of Plumbago rosea Linn. (Yoot), incorporated into ointments with yellow soft paraffin, have been investigated on rats. Wound healing activity was studied using excision and incision wound models in rats following topical application. Both plumbagin and the Plumbago rosea root extract produced a significant response in both of the wound models studied. The wound contracted in 14 days in the case of plumbagin (0.1%) and 16 days in case of Plumbago rosea root extract (0.5%), as against in 22 days in the case of control animals. The results were also comparable to those of a standard drug, framycetin sulphate cream (1% w/w) in terms of wound contracting ability, wound closure time, tensile strength of wound and regeneration of tissues at the wound site. Histological studies revealed evidences for the healing process by formation of fibrovascular tissue, epithelization and increased collagenization when compared to control.
