이 논문은 선박의 자동조타장치를 음성인식으로 제어할 수 있는 시스템을 개발하기 위한 기초연구로 SMCP(IMO Standard Marine Communication Phrases)에 제시된 조타명령문의 구성 형태를 분석하여 화자의 의도를 예측할 수 있는 특정 파라미터를 추출하였다. 그리고 이 파라미터를 이용하여 1차 패턴인식 과정으로부터 도출된 후보단어 집합으로부터 최종 단어를 결정하는 후처리 인식 프로시저를 설계하였다. 이 프로시저의 유용성을 검증하기 위하여 음성인식용으로 총 525개의 조타명령문을 획득하였고, 표준패턴 기반의 인식과정 인식률과의 비교실험을 수행하였다. 실험결과 의도예측 특정 파라미터를 이용한 인식 프로시저의 인식률이 약 42.3% 향상되어 유효함을 알 수 있었다.

Through the combination of existing tidal prediction model and numerical tidal model, the efficient tidal prediction system was formulated and applied to the neighboring area of Pusan port. Because all tidal constituents for tidal prediction (69 tidal constituents are normally used) couldn't be considered due to the physical limits on computing process, some errors between the observed and predicted values were inevitably occurred. But it was confirmed that the computed values with maximum 10% of relative errors can be obtained if four major tidal constituents(M2, S2, K1, O1) are used. Thus, if other constituents than four major tidal constituents are additionally used, more accurate values will be obtained. Furthermore, if the database for harmonic constants in coastal waters is made in advance, using the numerical tidal model, prompt tidal prediction can be achieved at any time when it is required.

In this study, some approximate theoretical solutions about oil spreading under the influence of gravitational and viscous forces have been derived from the viewpoint of energy conservation. The theoretical model which derived newly is in agreement with Toi's one derived from a different hypothesis, and shown to predict well the spreading distance of oil front at an initial step of outflow, but further study is necessary to evaluate the spreading distance after longer time

근래 해적에 의한 선박 피랍이 전 세계적으로 큰 문제가 되고 있다. 우리나라의 초대형 유조선 "삼호드림호"가 소말리아 해적에 의해 피랍되어 몸값으로 엄청난 액수를 지불하고 풀려났다. 그리고 2011년 1월 20일 "삼호쥬얼리호"의 경우 해군은 창군 이래 처음으로 공해상에서 해적과 교전하여 선원 21명 모두를 구출하는 쾌거를 이루어냈다. 또한, "한진텐진호"의 경우, 전 선원이 선원대피처로 신속하게 대피하여 모두 안전하게 해군에 의해 구출되었다. 이와 같이 우리나라 선박들이 해적에 의해 피랍되는 경우가 늘어나면서 해적의 위험으로부터 벗어날 수 있는 다양한 방법이 연구되고 있다. 정부는 2011년 1월 선박설비기준을 일부 개정하여 선원대피처를 지정된 위험해역을 항해하는 모든 선박에 설치하도록 강제화하였다. 따라서 이 연구에서는 선박 피랍의 위험상황 발생시 장시간 대피 거주해야 하는 선원대피처의 적정 규모를 선원들의 피난 안전성에 기초한 이론적인 산출과 FDS를 이용한 화재시뮬레이션을 통해 설정하고자 한다.

선박 조종방정식의 비선형 요소를 고려한 선박의 자동조타시스템의 제어기를 설계하기 위하여 TSK (Takagj-Sugeno-Kang) 퍼지 이론을 이용하였다. TSK 퍼지모델은 비선형 시스템을 매우 효율적으로 표현할 수 있으며, 또 TSK 퍼지모델은 결론부가 선형식으로 이뤄져 있어 체계적인 제어기 설계가 가능하다. 따라서 본 연구에서는 선박의 조종방정식을 TSK 퍼지모델로 표현하는 방법과 그 모델로부터 체계적으로 TSK 퍼지제어기를 설계하는 방법을 설명한다.

80,000 G/T급 크루즈선이 입항할 수 있는 터미널을 계획하고 있는 제주신항에 대하여 자연 ·환경 조건 및 방파제 등의 구조물 등을 고려하여 선박조종시뮬레이션을 실시하여 입 ·출항 및 접 이안의 안전성을 평가하고자 한다. 안전성 평가는 항로경계의 침범여부, 구조물과의 최근접거리, 선박조종자의 주관적 평가를 통계적으로 해석하는 방법을 이용하였다.

This paper aims to suggest the strategies for Korea port, especially Busan to develope into a viable transhipment center and/or Hub port as the articulation points between mainline and feeder nets. To tackle this goal, the authors clarify the requirements for Korea port which will be critical in determining its position as Hub trough the careful analysis on competitiveness, environmental impact, port policy and capacity, transhipment traffic and inherent ability to generate traffic. The results are summerized as follows. (1) Coping with increasing container volumes, new investment is sustainedly necessary to increase the capacity and inherent ability of container port and create economies of scale. Moreover, increasing port capacity will increase the potential for the Korea port's inclusion into mainline rather than feeder networks. (2) Considering an increasing awareness of need for customer-oriented operations and service quality rather than simply a reliance on infrastructure-led efficiency, privatization of one sort or another and corporation of port have been key strategies in achieving greater efficiency in Korea containerport.

It is one of the important study for improving education quality to investigate School climate, Campus Life and Academic Achievement in University. This study focuses on the of success / failure attribution in academic achievement and its internal-external attribution of Maritime college students. The main purpose of this study was investigate the relationship between the perception of college climate and attribution of success and failure about college life and cadet's academic performance. The subjects were 490 cadets of freshman, sophomore and junior of Korea Maritime University. The data was analysed by Pearson's correlation, one-way and simple factorial ANOV A, 2, and t-test by using SPSSWIN Ver. 7.5 programme. The major results of this study were as follows : 1. Social relationship orientation was higher than the others on the perception of college climate, while the relationship between professor and collegian was lower. 2. The most collegian recognized on the attribution of failure about the college life and the relationship between professor and collegian. But most collegian recognized on the attribution of sucess about collegian's relationship. 3. The perception of college climate and attribution of success / failure was not influenced on the student's academic performance and academic adaptability.

A vessel in distress might be well identified when both the variables affecting the drifting of the vessel and the extent to which the variables affect the drifted vessel are known. And also the disembarking place inside the ship might be easily located if the drifting poised is forecasted. The forecasting method of the drifting poise is resolved by combining the vectors of the current and the wind. It is, however, very hard to forecast the effect of the wind, which should be mainly determined by field survey. This study aims at identifying the drifting characteristics of medium/large ships, considering only the effect of the wind. The experiment revealed the following results. ① The drifting poise is determined by the aspect ratio of the ship and the shape of the superstructure of the ship. ② Drifting direction is quite stable when wind speed goes over a certain level. ˚led3 Drifting speed is 3-7% of the wind speed in case of T/S Hannara.

항만 설계에 영향을 미치는 네가지 중요요인인 선박요인, 인간요인, 환경요인 및 항로표지요인들이 실제 항만 및 수로의 설계에 미치는 구체적인 영향들을 각 요인별로 분석하였다. 아울러 항만 및 수로 설계요소인 수심, 항로의 폭, 항로의 배치, 선회수역의 크기 및 부두의 배치 문제에 대한 분석을 기하였다. 그리고, 항만 및 수로의 설계 문제에 관한 최근의 연구결과들과 각국의 설계 Guideline들을 수집하여 특히, 항로의 폭, 항로의 배치 그리고 선회수역의 크기에 대해 그 내용을 비교하고 분석하였다. 이들 연구 결과들과 항만 설계기준들은 연구 방법과 설계 기준을 마련한 기구들에 따라 그 내용의 차이가 있음이 확인되었다. 따라서 이들 기준들은 항만 설계를 위한 1차 계획 수립시에만 활용되고 세부적인 설계는 1차 설계 후 항만 설계 시뮬레이션 기법을 통한 검정을 거쳐야만 안전한 항만의 설계 및 개발이 이루어질 수 있다는 것이 확인되었다.

The purpose of this study was to explore the nature and progressional change in consciousness of KMU students about the shipboard-life which appeared though regimental dormitory life. An empirical study was carried out to exam in the perceptual differences not only on sea faring as a job but also on preliminary shipboard-life among each grades. The data analyzing perceptual differences on seafaring and preliminary shipboard -life of KMU students were collected from 450 students selected from 3 different kinds of populations -(1) senior students, (2) sophomore students, (3) freshmen-by the use of questionnaire method. The pearson's test for goodness offit and factor analysis were used to analyze the data.

Many studies have been done in the field of fuzzy logic theory, but it's application to the ship's steering system is few until this date. This paper is to survey the effect of application of fuzzy logic control by new compositional rule of Inference to the ship's steering system. The controller is made up of a set of Linguistic Control Rules which are conditional linguistic statements connecting the inputs and output, and take the inputs derived from deviation angle and it's angular velocity. The Linguistic Control Rules are implemented on the digital computer to verify the performance of the fuzzy logic controller and simulations have been done in six cases of initial condition and disturbance type. Consequently, it was proved that the ship's steering system by introducing the F.L.C. is performed efficiently and less energy loss system compared with the conventional autopilot.
