인공위성의 개발은 오랜 기간에 걸쳐 다양한 분야의 전문가들에 의해 개발된 결과물들이 통합되어 완성될 수 있다. 위성개발과 같이 많은 개발자가 공동으로 작업하여 하나의 결과물을 생산하는 경우 개발과정에서 방대한 양의 문서작업이 수반된다. 특히 비행소프트웨어와 같이 서로 다른 개발자에 의해 작성된 코드들이 하나의 이미지로 통합되어 빌드될 경우 발생하는 문제점들을 해결하고 요구되는 기능들을 디버깅하기 위해서는 개발과정 및 소스코드에 대한 문서들이 필수적이다. 이러한 소프트웨어 설계에 대한 문서는 그 양이 방대하고 소스코드와의 연계성이 필요하기 때문에 소스코드를 작성한 각 개발자들이 직접 수작업으로 문서를 작성하였다. 예를 들면, 기존의 위성비행소프트웨어 개발과정에서는 이러한 문서들 중 전체 위성비행소프트웨어의 단위 코드별 입출력, 수행기능 등의 상세 설계 내용을 기록하는 SDD(Software Design Description)는 개발자가 작성한 코드를 기반으로 수작업을 통하여 작성되었다. 이러한 작성방식은 작성자의 입력오류가 발생할 수도 있으며 소프트웨어 개발과 별도로 수작업이 요구되어 문서작성에 소요되는 시간적 손해가 발생하게 된다. 유럽에서는 이러한 문제점을 보완하기 위하여 C, C++, C#, JAVA, VHDL 등 다양한 언어를 사용하는 소프트웨어 개발에 적용 가능한 자동적 문서작성 도구인 Doxygen을 설계 및 개발문서 작성에 활용하고 있다. Doxygen은 PDF, HTML, Latex, RTF 등 다양한 출력 포맷도 지원한다. 본 논문에서는 Doxygen을 활용하여 위성비행소프트웨어 개발문서의 작성 시 소요시간을 단축하고 소스코드로부터 해당 설계 내용을 추출하여 자동적으로 문서를 작성할 수 있는 방안에 대하여 소개한다.

Form design for information registration should consider and classify various possible cases and each user case and reflect it in the design. In this paper, I analyzed the visual and emotional factors of information design that elicit positive emotions from the user experience point of view, focusing on the birth certificate of among other public documents issued by the government. In order to derive problems and supplements from the user's overall writing experience point of view, Keller's Motivational Behavior Construction Model was used. The process of writing the birth registration form creates recognition, reasoning, relationship, establishment, achievement, expectation. In order to more actively draw an emotional point of view, it is essential to set of information and to materialize the information experience. It is hoped that this will be a good guideline in the process of presenting a new perspective on information design and improving the experience.

Local culture is a cultural heritage that has come down from generation to generation in the natural environment of a region. It includes history, tradition, natural features, art, and historic relics. The Academy of Korean Studies has complied "The Encyclopedia of Korean Local Culture" using those local culture contents. Local culture content shave the features of documentary, such as authenticating the source, and managing hierarchy structure. Thus, to deal with local culture contents, a "circular knowledge information management system" is sought for that helps basic, fragmentary, and high-level information to circulate to create new knowledge information within the system. A user of this circular knowledge information management system is able not only to collect data directly in it, but also to fetch data from other database. Besides, processing the collected data helps to create new knowledge information. But, it's very difficult to sustain the features of the original hierarchy bearing meaning contained in the various kinds of local culture contents when building a new database. Moreover, this kind of work needs many times of correction over a long period of time. Therefore, a system in which compilation, correction, and service can be done simultaneously is needed. Therefore, in this study, focusing on the case of "The Encyclopedia of Korean Local Culture", I propose a XML-based digital compilation management system that can express hierarchy information and sustain the semantic features of the local culture contents containing lots of ancient documents, and introduce the expanded functions developed to manage contents in the system.

This study empirically analyzed a Korean pre-trained language models (PLMs) designed for natural language generation. The performance of two PLMs - BART and GPT - at the task of abstractive text summarization was compared. To investigate how performance depends on the characteristics of the inference data, ten different document types, containing six types of informational content and creation content, were considered. It was found that BART (which can both generate and understand natural language) performed better than GPT (which can only generate). Upon more detailed examination of the effect of inference data characteristics, the performance of GPT was found to be proportional to the length of the input text. However, even for the longest documents (with optimal GPT performance), BART still out-performed GPT, suggesting that the greatest influence on downstream performance is not the size of the training data or PLMs parameters but the structural suitability of the PLMs for the applied downstream task. The performance of different PLMs was also compared through analyzing parts of speech (POS) shares. BART's performance was inversely related to the proportion of prefixes, adjectives, adverbs and verbs but positively related to that of nouns. This result emphasizes the importance of taking the inference data's characteristics into account when fine-tuning a PLMs for its intended downstream task.

With the development of deep learning technologies, Artificial Intelligence powered Optical Character Recognition (AI-OCR) has evolved to read multiple languages from various forms of images accurately. For the financial industry, where a large number of diverse documents are processed through manpower, the potential for using AI-OCR is great. In this study, we present a configuration and a design of an AI-OCR modality for use in the financial industry and discuss the platform construction with application cases. Since the use of financial domain data is prohibited under the Personal Information Protection Act, we developed a deep learning-based data generation approach and used it to train the AI-OCR models. The AI-OCR models are trained for image preprocessing, text recognition, and language processing and are configured as a microservice architected platform to process a broad variety of documents. We have demonstrated the AI-OCR platform by applying it to financial domain tasks of document sorting, document verification, and typing assistance The demonstrations confirm the increasing work efficiency and conveniences.

Web applications based on J2EE($Java^{TM}$ 2 Platform, Enterprise Edition) were occurred for solution to overcome the limitations in time and space that the former applications had. Recently, lots of solutions using frameworks are being suggested to develope applications more quickly and efficiently. In this paper, we propose the template for several processes and types, which should be taken in presentation layer of web applications. This idea was based on the fact that web applications developers can concentrate on their specific tasks with independent manner in layered architecture. This template is XML-typed document that shows information about presentation layer of Web applications, which the user wants to compose. This template is inputted to the code generator. After then, the code generator generates skeleton code in presentation layer automatically after parsing information of XML documents. It means that we can develope Web applications more efficiently, by constructing skeleton code which inherits from hot spot classes of framework. Using this template and code generator, developer can develop Web applications with little practice and also is easy to cooperate with other developers to develop them just in time with distributing the standard development process.

Legislation are social norms that give directly or indirectly, huge impact on the social or corporate, personal problems, unlike a normal document. Also, over time it has a feature constantly changing by the laws enactment and amendment, repealed. The amendment statement automatic generated system is used for purpose of proclamation to those. However, existing system is able to generate amendment statement just text body of law how compare and analyze the current legislation and amendment legislation. However, actual legislation to be created attached table of the table form in complex structure besides simple text form as body text. In this paper, we additional implement attached table processing to existing the amendment statement automatic generated system that containing the table does not handle attached table. We were analyse to the amendment statement generated grammar and table structure in attached table of the legislation for processing to attached table. Also proposed a method to compare attached table in the table. So, it is enable the automatic generation with amendment statement which various forms of legislation the documents.

We propose a web document transcoding technique that translates existing web pages designed for desktop computers into an appropriate form for hand-held devices connected to the wireless internet. By defining a content block based on a visual separation and using it as a minimum unit for analyzing and converting processes, we can get web pages converted more exactly. We also apply the reallocation of the content block and the generation of new index in order to provide convenient interface without left-right scrolling in small screen devices. These methods, compared with existing ways such as text level summary or partial extraction method, can provide efficient navigation and a full recognition of web documents. To gain those transcoding benefits, we propose the Layout-Forming Tag Analysis Algorithm that analyzes structural tags, which motivate visual separation and the Component Grouping Algorithm that extracts the content block. We also classify and rearrange the content block and generate the new index to produce an appropriate form of web pages for small display devices. We have designed and implemented our transcoding system in a proxy server and evaluated the methods and the algorithms through an analysis of transcoded results. Our transcoding system showed a good result on most of popular web pages that have complicated structures.

Today's war fields can be characterized by net-centric wars where a variety of independent weapon systems are operated in connection with each other via networks. As such, weapon systems become dramatically advanced in terms of complexity, functionality, precision and so on. It is then obvious that the defense R&D of those requires systematic and efficient development tools enabling the effective management of the complexity, budget/cost, development time, and risk all together. One viable approach is known to be the development methods based on systems engineering, which is already proved to successful in U.S. In this paper, a systems engineering approach is studied to be used in the conceptual design of advanced weapon systems. The approach is utilizing some graphical models in the design phase. As a target system, an unmanned aerial vehicle system is considered and the standard SysML is also used as a modeling language to create models. The generated models have several known merits such as ease of understanding and communication. The interrelationships between the models and the design artifacts are identified, which should be useful in the generation of some design documents that are required in the defense R&D. The result reported here could be utilized in the further study that can eventually lead to a full-scale model-based systems engineering method.
