Company A, an embedded system manufacturer, has been managing multiple development projects. Executives need to understand the risk level of every project and prioritize resource distribution. Traditional project monitoring tools or excel sheets are too complex for calculating the risk factors across a functional organization. Two new charts, "Spear-head Chart" and "Float Chart" were designed to assist high level decision making processes. Two charts were used for weekly executive meetings in order to monitor project progress and rectify project direction. One page graphical monitoring tools in Company A are good enough for high management decision making. Authors explain the characteristics of two charts and propose its practical implementation in real working environment. Spear-head chart was also implemented as a system.

Evolutionary operation is a useful tool for improving full-scale manufacturing process by systematically changing the levels of the process variables without jeopardizing the product. This paper presents a system design for the evolutionary operation software called 'evolutionary optimizer'. Evolutionary optimizer consists of four modules: factorial design, many variables, mixture, and mean/dispersion. Context diagram, data flow diagram and entity-relationship modelling are used to systematically design the evolutionary optimizer system.

This paper describes IDMS, a graph-based modeling system that supports problem structuring. We employs influence diagram as a problem representation tool, that is, a modeling tool. In particular, IDMS is designed as domain-independent shell. Therefore, a modeler can change the contents of the knowledge base to suit his/her own interested domain. Since the knowledge base of IDMS contains both modeling knowledge and domain knowledge, IDMS provides not only the syntactic support for modeling tool, but also the semantic support for problem domain. To apply the method in the real world context, we tested IDMS on the process selection problem in business reengineering, which is typical semi-structured problem.

본 논문은 Computer Aided Software Engineering (CASE) Tool을 이용할 경우의 Safety Critical 소프트웨어 개발 방법론인 구조적 분석 및 구조적 설계 모델링 방법론을 Teamwork CASE tool의 예를 중심으로 제안하고자 한다. 제시된 사례는 NSIS(Nuclear Safety Information System)으로서 Essential Modeling과 Implementation Modeling을 제시하였는데 Teamwork CASE 환경하에서의 분석 및 설계 절차, 지침 등을 제시하였다. Essential Modeling에서는 NSIS의 MMIS 분석범위 및 External Interface를 제시하는 환경 모델(Environmental Model)과 MMIS의 기능을 계층구조적으로 분할하는 행위모델링(Behaviroal Modeling)을 각각 Context Diagram과 Data Flow Diagram (DFD)으로 그 과정을 제시하였다. Implementation Modeling에서는 Essential Modeling으로 부터 나온 결과물을 토대로 Boss Rule, Transform Rule과 Transaction Rule 등을 거쳐 NSIS MMIS의 설계 근간이 되는 Structured Chart(SC)를 제시하였다. 본 논문에서 제시된 모델링 방법론을 통하여 Safety Critical 소프트웨어 개발시 Teamwork CASE Tool을 활용할 수 있음과 동시에 분실 및 설계의 일치성을 통하여 Safety Critical 소프트웨어의 안전성 확립과 품질보증 목표에 기여할 수 있다.

Model-based software architecture verification and test scenarios generation are becoming more and more important in the software industry. Based on the existing temporal graph grammar, this paper proposes a new formalization method of the context-sensitive graph grammar for aiming at UML activity diagrams, which is called the UML Activity Graph Grammar, or UAGG. In the UAGG, there are new definitions and parsing algorithms. The proposed mechanisms are able to not only check the structural correctness of the UML activity diagram but also automatically generate the test scenario according to user constraints. Finally, a case study is discussed to illustrate how the UAGG and its algorithms work.

과학기술의 발달은 문명의 편리성을 동반하였으나 더불어 원자력 및 가스 등의 폭발, 유출사고 발생 그리고 세계각지에서 화생방 테러 발생 가능성을 가지고 있어 총괄적 대응노력이 국가적으로 시급한 과제로 대응하고 있다. 본 연구는 미국과 캐나다의 CBRN 교육프로그램을 조사 분석하여 우리나라 현실에 맞는 CBRN 교육훈련 프로그램을 개발하였다. 또한 한국형 화생방 교육훈련 프로그램 개발을 위하여 Activity-Action Diagram 기법을 활용 화생방 시나리오의 각 이벤트별로 대응 시 취해야 할 요구사항을 Activity로 정의하고 이의 세부적인 조치사항을 Action으로 정의하여 화생방 상황에 맞는 행동을 정의하여 실질적이고 체계적인 화생방교육훈련 프로그램을 제안함으로서 예방, 대응, 구조의 기능을 활성화하고 특히 CBRN 사태발생시 초기대응 교육훈련 프로그램을 구축하였다.

현재 급속도로 성장하는 인터넷과, PC의 하드웨어, 소프트웨어를 기반으로, 대기업 외에도 중소기업, 소호에서도 대부분의 업무가 네트워크를 활용한 PC 기반으로 연화하고 있다. 하지만 각각의 업무 특성에 고려되지 않은 PC 환경은 사용자들에게 불편함을 야기시키고 이에 따라 각자 환경에 특성화된 PC/Network 서비스의 출현이 예고되고 있다. 본 연구에서는 소호와 중소기업을 대상으로 한 PC 사용자의 이용 행태를 맥락 질문법을 중심으로 이용 행태에 대한 Raw data 를 수집하였고, 분석에서는 Affinity Notes 와 사용자 Modeling 등의 해석 과정을 거쳐, 사용자의 PC/Network 사용 패턴, 환경, 행대 등을 Affinity Diagram 으로 분류화하였다. 분류화된 데이터와 사용자의 Metal Model 을 중심으로 크게 3 가지의 뚜렷한 사용자 이용 행태에 대한 유행을 도출할 수 있었다. 첫 번째 사용자 유행은 업무에 필요하다면 자유롭게 PC 및 네트워크를 사용하여 작업을 수행하는 'Holistic Networker' 이고, 두번째는 자신의 업무에 관해서는 능동적이지만 외적인 부분은 배타적이며 수동적인 'Unplugged Controller' 그리고 마지막 유형으로는 주어진 여건에서 벗어나지 않고 업무를 진행하는 'Passive Reactor'로 분류 할 수 있었다. 이러한 유행은 각각의 성향을 제시할 수 있었고, 이러한 유행과 성향을 바탕으로 PC/Network 기반 시스템제작 시, 서비스 정의, 기능 도출 등에 기초가 될 수 있을 것이라 본다.

When new services are introduced, one of the drivers for market performance of them is the interactions among existing and new services. They are characterized by the substitution or complementary effects among existing and new service or the cannibalization of existing services by new services. This paper analyzes these issues in the telecommunications service industry context. To analyze them, a simple graphical tool or State Transition Diagram(STD) is developed and used. The diagram helps to clearly represent and explain the substitution, complement and cannibalization impact. Then, using the face-to-face survey of 1,200 people, a new wireless internet access service or WiBro is analyzed to identify the substitution/complement and cannibalization impacts in relation with the other competing services. Additionally, the important factors explaining customer subscription and substitution behavior are identified. The analysis results indicate that males, students or on-line game users are more likely to subscribe WiBro. Also, among the potential WiBro subscribers, customers who are less satisfied with the existing fixed line broadband internet access services are more likely to stop subscribing the fixed line service, which implies substitution by a new service. Additionally, this raises the issue of cannibalization if the existing and new services are provided by the same company. In fact we find the cannibalization effect is more serious for the cost sensitive group. We believe that our tool, approach, analysis results and their implications would be very helpful to devise a winning strategy for the new services in the highly uncertain telecommunications business environment.

Acceleration of globalization in almost all industries, including fisheries, already had been a major paradigm of the age. And It has been weakened its meaning of geographical, cultural and economic boundaries between the nations. In particular, various changes in the fisheries environment have exceeded the area of problem for conventional single country is resolved. And if there is no cooperation with international cooperation other problems also almost nearly impossible to alleviate or solve. So it has emerged in this context, the concept of sustainable development and conceptual diagram of responsible fisheries. However, it has been passed about 20 years since the FAO documents published, there is little interest in it. In this study, analyzed the characteristics of the changes and its constitutive trends and contents of the FAO's responsible fisheries documents. And proposed both the need for analysis and research for the fisheries in an international context for the future and educational aspects. The results of this study show that FAO related documents are hardly to find that have been translated into Korean, in particular since the 2000s. And it is fairly skeptical whether there is a direct effective in fisheries in terms of language barriers. Therefore, the study on responsible fisheries much more important to develop the current status and future-oriented policy of international fisheries even in fisheries related education.
