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.

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.

본 연구는 축구팀 주장의 임파워먼트가 역할지각 및 팀 응집력에 미치는 영향을 살펴보고자 하였다. 연구의 목적을 달성하기 위해 부산광역시 및 경상남도 소재 초·중등학교 축구팀 및 축구클럽 주장학생을 대상으로 154명의 자료를 수집 후 SPSS statistic 25.0 프로그램을 이용하여 탐색적 요인분석, Cronbach's α 계수 산출 및 상관관계분석, 조사도구의 신뢰도와 타당도를 검증하였다. 이 후 가설검증을 위한 중다회귀분석 결과는 다음과 같다. 첫째, 축구팀 주장의 임파워먼트는 역할지각에 부분적으로 긍정적인 영향을 미치는 것으로 나타났다. 둘째, 축구팀 주장의 임파워먼트는 팀 응집력에 부분적으로 긍정적인 영향을 미치는 것으로 나타났다. 셋째, 축구팀 주장의 역할지각은 팀 응집력에 부분적으로 긍정적인 영향을 미치는 것으로 나타났다. 따라서 축구팀 주장의 임파워먼트를 통해 팀 내 맡은 역할과 팀 응집력을 높일 수 있도록 해야 할 것이다.

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.

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.
