Design and Implementation of a Relational Database for Management of UML Models

The UML (Unified Modeling Language) is a modeling language for specifying, visualizing, constructing, and documenting systems. It also supports systematically the design and development of systems. There may be a large number of models to be managed in a real modeling environment. A methodology to save and retrieve the models effectively, therefore, needs to be developed. This thesis focuses on the class diagram which is the core part of UML. It proposes a database supported methodology for the management of class diagrams. In the proposed methodology, class diagrams are saved in and retrieved from a relational database. To save a class diagram in the database, the constitution of the class diagram is translated in terms of relational tables. To retrieve a class diagram from the database, the user- specified query is translated into the SQL (Structured Query Language), and then the constituent of the class diagram is searched from the tables in the database. The proposed methodology can exploit the function of the relational database such as managing a large number of models, sharing the models among users, and fast queries. It, therefore, provides a powerful framework for an effective management of UML models and a fast development of systems.Abstract = ⅱ 제 1 장 서론 = 1 제 2 장 UML 및 UML 개발 도구 = 4 2.1 UML의 구성 요소 = 4 2.2 UML 클래스 다이어그램(Class Diagram) = 6 2.2.1 클래스(Class)와 인터페이스(Interface) = 7 2.2.2 관계(Relationship) = 8 2.3 UML 개발 도구 = 10 제 3 장 UML 클래스 다이어그램의 저장 및 검색 = 12 3.1 UML 클래스 다이어그램 변환 = 12 3.2 관계형 데이터베이스 생성 및 저장 = 17 3.3 UML 클래스 다이어그램 검색 = 21 제 4 장 구현 및 기존 시스템과의 비교 = 23 4.1 알고리즘 및 시스템 흐름도 = 23 4.2 데이터베이스 테이블 상세 설계 = 26 4.3 시스템 구현 = 33 4.4 기존 시스템과의 비교 = 35 제 5 장 결론 및 향후 연구과제 = 36 참고 문헌 = 3

Development of an Auto-Trim Control System for Ro-Ro Ship Carrying Heavy Cargoes

In Ro-Ro ship carrying heavy cargoes, it is very important to maintain a certain level of aft draft and the proper trim through the entire loading or discharging process. Some kinds of manual ballast control system have been generally applied so far to this practice in Ro-Ro ship. However, there is need to develop a so-called Auto-Trim Control System using some computer technology to improve the operation of those existing systems. This paper aims at developing an Auto-Trim Control System especially for Ro-Ro ship carrying such heavy cargoes including hot coils and steel plates. The author carried out some systems analysis and design for developing the system by examining and reflecting the practices of the entire loading and discharging process. Then a user-friendly Auto-Trim Control System has been built by interfacing the Valve Remote Control system and Tank Level & Draft Measuring system with itself. The author also provides some excellent results on the performance of the system by reporting the records of installing the system on board 4 Ro-Ro ships.Abstract 제 1 장 서론 = 1 1.1 연구의 배경 = 1 1.2 연구의 목적 = 2 제 2 장 시스템의 개요 = 3 2.1 중량화물 선적 Ro-Ro 선 하역 작업의 기본개념 = 3 2.2 Auto-Trim Control System의 기본개념 = 7 2.3 시스템 구성도 = 10 제 3 장 선미흘수 및 트림 제어 알고리듬의 개발 = 11 3.1 탱크 배치도 = 11 3.2 탱크 배정 우선순위 = 11 3.3 탱크 선택 규칙 = 12 제 4 장 Auto-trim Control System 개발 = 15 4.1 시스템 소프트웨어 구성 = 15 4.2 시스템 설계 = 16 4.3 밸브 및 펌프 작동 절차 = 21 4.4 시스템 구현 = 37 제 5 장 프로그램 실행 예 = 42 5.1 통신상태 표시줄 = 42 5.2 선박상태 표시줄 = 44 5.3 프로그램 작동 = 45 제 6 장 결론 = 58 참고문헌 = 6

A Study on Flow Zone Development and Botton change gy Propeller Jets from Ships

The flow zone through propeller jets is used in evaluating the environmental and constructional effects of navigation on the waterways. Water in this zone can go through the propellers but not all water in this zone will go through the propellers. It relies on the characteristics of ships and water depth. A numerical model using the momentum theory of the propeller and Shield's diagram was developed in a restricted waterway. Equations for discharge are presented based on thrust coefficients and propeller speed and are the most accurate means of defining discharge. Approximate methods for discharge are developed based on applied ship's power. Equations for discharge are as a function of applied power, propeller diameter, and ship speed. Water depth of the waterway and draft of the ship are also necessary for the calculation of the grain size of the initial motion. The velocity distribution of discharge from the propeller was simulated by the Gaussian normal distribution function. The shear velocity and shear stress were from the Sternberg's formula. Case studies to show the influence of significant factors on sediment movement induced by the ship's propeller at the channel bottom are presented. The first case is for large ships passing through the navigation channel and berthing and unberthing at container terminal at Kwang Yang harbor. Eleven ships are considered, including naval ship, tanker and bulk carriers. The second case is for the commercial moving tow and the barge. The combined effects of the propeller jet and the wake flow a moving barge are investigated.목차 ABSTRACT = i LIST OF TABLES = v LIST OF FIGURES = vi NOMENCLATURE = ix 제1장 서론 = 1 1.1 연구의 배경 = 1 1.2 연구의 목적 및 내용 = 2 1.3 연구의 방법 = 2 제2장 기본이론 = 5 2.1 추진기 배수류 이론 = 5 2.1.1 추진기 배수류의 속도분포 = 6 2.1.2 추진기에 의한 운동량 이론 = 16 2.1.3 속도분포 = 23 2.2 표사 수송이론 = 28 2.2.1 이론적 배경 = 28 2.2.2 소류사 수송이론 및 방정식 = 28 2.2.3 부유사 수송이론 및 방정식 = 33 2.2.4 표사이동의 결정이론 = 37 제3장 수치모델수립 및 적용 = 42 3.1 대형선박에 대한 모델 구성 = 42 3.1.1 실제 수역과 제한수로에 대한 적용 = 42 3.1.2 저면전단응력의 산정 = 46 3.2 예인선의 모델 구성 = 50 3.2.1 추진기 제트의 유속 산정 = 51 3.2.2 저면 전단응력의 산정 = 57 제4장 수치실험 결과 및 분석 = 61 4.1 제한수로 및 부두전면에서의 적용 = 61 4.1.1 제한수로에 대한 적용 = 61 4.1.2 부두 전면에 대한 적용 = 79 4.2 예인선에 대한 적용 = 104 4.2.1 대상선박의 특성 및 조건 = 104 4.2.2 수치모형의 검증 = 105 4.2.3 적용결과 및 분석 = 108 4.3 저면변형에 대한 고찰 = 114 제5장 결론 = 120 참고문헌 = 12

A Study on the Fingerprint Recognition Method Directional Feature Detection using Neural Networks

Fingerprint-based identification is known to be used for a very long time. Owing to their uniqueness and immutability, fingerprints are today the most widely used biometric features. Therefore, recognition using fingerprints is one of the safest methods as a way of personal identification. In this paper, a fingerprint identification method using neural networks and the direction feature vectors based on the directional image extracted from gray-scale fingerprint image without binarization and thinning is proposed. The basic idea of the above mentioned method is to track the ridge lines on the gray-scale image, by ？ailing according to the local orientation of the ridge pattern. A set of starting points are determined by superimposing a grid on the gray-scale image. A labeling strategy is adopted to examine each ridge line only once and locate the intersections between ridge lines. After the direction feature vectors are consisted of vectors by four direction labeling. Matching method used in this paper is four direction feature vectors based matching. The experiment are used total 124 feature patterns of four fingerprints, and One fingerprint image is consisted of 31 feature patterns. The results is presented excellent recognition capability of learned fingerprint images.Abstract(Korean) = 2 Abstract(English) = 3 Chapter 1 Introduction = 4 Chapter 2 Neural networks = 6 2.1 Introduction of neural networks = 6 2.2 Investigation between biological and artificial neuron = 7 2.3 Learning and structure of multilayer neural network = 10 2.4 Multilayered neural networks used experimental = 14 Chapter 3 Fingerprint recognition = 15 3.1 Direction feature vector detection = 15 3.2 Tangent direction computation = 18 3.3 Four direction labeling and pattern detection = 20 Chapter 4 Experimental results = 25 4.1 Experimental environment and method = 25 4.2 Experimental results = 29 Chapter 5 Conclusion = 40 References = 4

A Phonetic Description of Korean Vowels

The aim of this paper is to describe the phonetic value of the Korean vowels, particularly those of what is commonly referred to as Standard Korean" or Seoul Speech". The paper begins by discussing the validity of the traditional definition of Standard Korean" or Seoul Speech". A critical appraisal of the traditional definition reveals that it is no longer entirely adequate now as it used to be and consequently there is a need for substantial modifications of the current definition. A tentatively modified definition of Seoul Speech" reads: A Korean dialect spoken by educated people of over thirty years of age, born or brought up in Seoul area". The phonetic description of vowels in th is paper is based largely on the auditory judgment of the writer and the scale employed for description is the cardinal vowel system and the vowel quadrilateral of the International Phonetic Association, by reference to which important allophonic variations of the vowel phonemes as conditioned by various features such as stress and / or quantity are examined and described. Thus vowels are examined in three different context

지속가능개발과 녹색(그린) GNP

원래 GNP는 전시에 국가의 물자동원 능력을 점검하기 위한 목적에서 작성되었다고 한다. 세계 제2차대전 때에 미국이 전시 물자동원능력 및 이의 국민경제에 미치는 영향을 알아보기 위해서 국민총생산에 대한 자료를 정리하기 시작하였는데, 미국 뿐만 아니라 영국 캐나다 등 몇몇 나라들이 비슷한 목적으로 비슷한 자료를 정리한다는 것이 알려지면서 1945년에는 당시 국제연맹의 주관아래 국민소득을 계정화하기 위한 국제회의도 개최된 바 있었다. 그러다가 1947년 미국이 오늘 날에 보는 것과 비슷한 국민소득계정을 독자적으로 개발하여 발표하였다. 1952년에 와서 유엔은 국민소득통계 국제적 표준인 국민회계체계 SNA(System of National Accounts)를 제정하였고 이어서 1968년에 이를 수정하여 신SNA를 만들었다. 우리나라의 GNP도 유엔이 권장하는 신SNA방식에 따라 한국은행이 추계한다. 이 같이 그 동안 여러 차례에 걸쳐 계측방법에 수정이 있었다고는 하지만 어떻든 전시 물자동원능력을 점검하기 위한 지표가 국민복지 수준이나 선·후진국을 비교하는 잣대로 확대적용된 데에는 GNP라는 지표가 우리 현실의 많은 부분을 생략한 극히 추상적인 지표라는 점을 망각한 소치이다. 그래서 1970년대 이후 GNP는 국민의 복지는 물론이고 경제적 성과도 제대로 반영하지 못한다는 신랄한 비판이 쏟아져 나오기 시작한 것은 당연한 귀결이라고 할 수 있다. 지금 까지 GNP에 대해서 제기된 문제점이 16-17가지에 달하고 있다고 한다. 이제 막 범지구적 명분으로 굳어지려는 지속가능개발의 개념은 이제까지 세계 각 나라가 최고의 경제정책 지표로 삼아온 GNP의 일대 수정 내지는 새로운 지표의 개발을 강력하게 요구하고 있다
