In AI image generation tools, most general users must use an effective prompt to craft queries or statements to elicit the desired response (image, result) from the AI model. But we are software engineers who focus on software processes. At the process's early stage, we use informal and formal requirement specifications. At this time, we adapt the natural language approach into requirement engineering and toon engineering. Most Generative AI tools do not produce the same image in the same query. The reason is that the same data asset is not used for the same query. To solve this problem, we intend to use informal requirement engineering and linguistics to create a toon. Therefore, we propose a sequence diagram and image generation mechanism by analyzing and applying key objects and attributes as an informal natural language requirement analysis. Identify morpheme and semantic roles by analyzing natural language through linguistic methods. Based on the analysis results, a sequence diagram and an image are generated through the diagram. We expect consistent image generation using the same image element asset through the proposed mechanism.

In software engineering, requirement analysis is an important task throughout the process and takes up a high proportion. However, factors that fail to analyze requirements include communication failure, different understanding of the meaning of requirements, and failure to perform requirements normally. To solve this problem, we derived actors and behaviors using morpheme analysis and BERT algorithms in the Korean requirement document and constructed them as ontologies. A chatbot system with ontology data is constructed to derive a final system event list through Q&A with users. The chatbot system generates the derived system event list as a requirement diagram and a requirement specification and provides it to the user. Through the above system, diagrams and specifications with a level of coverage complied with Korean requirement documents were created.

Software testing 은 소프트웨어 개발 과정 중에 1/3 을 차지 할 만큼 중요한 부분 중 하나이다. Software testing 는 Requirement 작성이 제대로 이루어져야만이 제대로 testing 을 할 수 있고, 그에 따라 정확한 결과를 얻을 수 있다. 그 만큼 Requirement 작성이 중요시 되고 있지만, 수동적으로 기술자에 의해서 작성되는 Requirement 에는 많은 문제점을 안고 있다. 본 논문에서는 Requirement를 Graph 하게 표현한 방법을 소개하고, 표현된 방식을 이용하여 다시 자연어로 표현할 수 있도록 Database 를 설계하는 방식을 제안한다. 그 결과로 Design 된 패턴들을 이용하여 Requirement 자연어로 기술한다. 이를 통하여 Requirment 기술 방식을 통일화 시킬 수 있으며, 기술자간에 의사소통을 원할하게 수행할 수 있으며, Software testing 의 중요 기반으로 제공할 수 있다.

소프트웨어 생명주기는 요구분석, 설계, 구현, 유지보수 단계 등으로 구성되며, 각 단계의 산출물은 다양한 형태를 지니고 있다 이러한 산출물을 표준화한 것이 UML이며, 요구분석 단계에서는 클래스 다이어그램, 사용사례 다이어그램, 활동 다이어그램, 협력 다이어그램이 일반적으로 사용되고 있다. 기존의 UML 개발 도구들은 이러한 다이어그램을 파일에 저장하기 때문에, 다이어그램 정보를 검색하거나 다수의 개발자들이 참석하는 공동 작업시 어려움이 발생한다. 본 논문에서는 이러한 어려움을 해결하고 요구분석 단계에서의 산출물을 효율적으로 처리하기 위하여 다이어그램 정보를 데이타베이스에 저장하고 관리하는 방법을 제안한다. 이를 위해 클래스, 사용사례, 활동, 협력 다이어그램을 구성하고 있는 모든 요소들을 분류하고, 분류된 각 구성요소들을 관계형 테이블로 변환한다. 이렇게 변환된 테이블에 다이어그램 정보를 저장하고 다양한 형태의 질의를 통해 저장된 정보를 검색할 수 있도록 한다. 제안한 방법은 다이어그램 정보를 다수의 개발자가 공유하여 사용할 수 있으며 모델의 재사용에 편리성을 제공할 것이다.

The current software industry has an emerging issue with natural language-based requirement specifications. However, the accuracy of such requirement analysis remains a concern. It is noted that most errors still occur at the requirement specification stage. Defining and analyzing requirements based on natural language has become necessary. To address this issue, the linguistic theories of Chomsky and Fillmore are applied to the analysis of natural language-based requirements. This involves identifying the semantics of morphemes and nouns. Consequently, a mechanism was proposed for extracting object state designs and automatically generating code templates. Building on this mechanism, I suggest generating natural language-based comic images. Utilizing state diagrams, I apply changes to the states of comic characters (protagonists) and extract variations in their expressions. This introduces a novel approach to comic image generation. I anticipate highly productive comic creation by applying software processes to Cartoon ART.

This paper describes the application of a model-based system design method critical to complex intelligent systems, PSARE, to a welding robot development to define its top level architecture. The PSARE model consists of requirement model which describes the core processes(function) of the system, enhanced requirement model which adds technology specific processes to requirement model and allocates them to architecture model, and architecture model which describes the structure and interfaces and flows of the modules of the system. This paper focuses on the detailed procedure and method rather than the detailed domain model of the welding robot. In this study, only the top level architecture of a welding robot was defined using the PSARE method. However, the method can be repeatedly applied to the lower level architecture of the robot until the process which the robot should perform can be clearly defined. The enhanced data flow diagram in this model separates technology independent processes and technology specific processes. This approach will provide a useful base not only for improvement of a class of welding robots but also for development of increasingly complex intelligent real-time systems.

Company A should maintain myriad conversion tools for the purpose of making a geometric compilation of navigation maps. Company A is already using complex compilation tools, which are tailored to geographical areas and various GPS models. However, due to frequent requirement and personnel changes, there is an endless challenge for perfect tool configuration and multiple map consolidation. To solve this problem, Company A launched a process automation project using Graphviz, which is an open source workflow graph visualization software. Before implementation, they had to document their current map compilation processes and then match it with the applicable conversion tool. For effective representation of process controls, a new graphical process notation is designed, i.e. Y Block diagram. The authors will compare Y Block diagram with other process notations and explain why Y Block diagram is more useful for tool based business processes such as digital map generation processes.

Development of complex discrete event simulators requires cooperation between domain experts and modeling experts who involve the development. With the cooperation the domain experts derive user requirement and modeling experts transform the requirement to a simulation model. This paper proposes a method for consistency verification of simulation model in DEVS formalism against the user requirement in UML diagrams. It also presents an automated tool, called VeriDEVS, which implements the proposed method. Inputs of VeriDEVS are three UML diagrams, namely use case, class and sequence diagrams, and DEVS Graph, all in Visio; outputs of a verification result is represented in PowerPoint files.

This paper describes modeling & simulation(M&S) model for dynamic analysis of helicopter rotor blades. Simulation model is developed using Dymola tool which implements the open source language - Modelica. Modelica is appropriate for developing multibody dynamic analysis model. To develop an M&S model efficiently, model based systems engineering(MBSE) is applied. Some diagrams such as requirement diagram, block definition diagram and sequence diagram etc. are drawn to capture the concept of M&S model. This activity is done utilizing the open source tool - Papyrus.
