Researchers require repetitive works such as data format analysis, reformatting and map reprojection in order to use geospatial data. To solve above problems, they are building web-based simulation systems with web developers. But the web-based systems are not efficiently developed because there is not the appropriate simulation framework for a web-based system using geospatial data. In this study, the geospatial simulation framework that can be effectively applied to the web-based system was designed and proposed. Also, the framework was composed of 7 modules; web mapping service, GIS mapping, statistics, model, processing,graphics, and geospatial datasets. In order to evaluate the effectiveness of the framework, a case study of urban growth has been verified. Experts who are not specialized in geospatial information disciplines expect to build easily a web-based system using geospatial data.

Currently interests of embedded software in various areas such as automotive field, ship field, robot field is increasing according to expand market of embedded systems. Various researches such as embedded operating systems, embedded software modeling technique, embedded software testing, and so on are going in progress. However systematic engineering approach in embedded system development is poor because embedded areas focus on hardware parts until now. Furthermore, framework-based de sign technique considering reusability is not reflected in embedded system development. Those development results in many of dead codes scattered in system, and results in poor reusability of system. This paper suggests a framework of embedded system for reusability and a static meta-model for reuse framework. Proposed meta-model expresses not only the structure of reuse framework, but also allows a designer to extend and design easily models of embedded system based on reuse framework according to various embedded system types.

In this paper, we present a new framework and stream synchronization mechanism to effectively support developing real-time multimedia streaming services by using a real-time object model named TMO (Time-triggered Message-triggered Object). The purpose of the framework is twofold. Firstly, the framework helps developers to design complex distributed real-time multimedia streaming services. Secondly, it supports timely streaming facilities. In order to achieve these goals, our framework is consist of Multimedia Streaming TMO, MMStreaming TMO Support Library and TMO Support Middleware. The time-triggered spontaneous feature of the MMStream TMO and a global-time based synchronization scheme is used as a regulator against the irregular deliveries and processing of media units caused by QoS non-guaranteed systems and communication channels. In conclusion, timely service capability of our framework is expected to contributed to overall enhancement of the real-time multimedia streaming.

In this paper I present the framework for programming education relating to the programming course in university. First of all, I identify the literature of the psychological and educational study of programming in domestic and foreign country. Some outstanding papers in foreign country show that the mental model, programming knowledge and strategies are the important difference between novice and expert programmers. And various problems experienced by novice programmers are identified. I summarise this material and suggest some practical implications for programming teachers in their teaching activity. The framework for programming education presented by this work has three dimensions of program development process, programming learning factors and teaching and learning methods for programming to develope the novice's programming skill. It helps the programming teacher to design, implement and evaluate their programming course with the guideline of programming activities.

The aim of this paper is to develop a framework of weather information services which is for processing contents and providing proper contents to new-media such as outdoor electronic display, DID (digital information display), and terrestrial multi-channel broadcasting, etc. By introducing the analysis of media use and perception science of human intelligence, the contents producing method to improve recognizing rate for weather information is provide and the layered framework of weather information services for new-media is designed. It integrates many different services to the framework. It can prevent duplicate investment for services and serve a major momentum to technical progress.

규칙 기반의 챗봇(Chatbot)은 개발자가 미리 지정한 키워드와 패턴을 통해 사용자의 의도(Intent)를 파악하기 때문에, 챗봇을 응용한 어플리케이션에서는 제한적인 활용도를 보인다. 본 논문에서는 위 문제를 해결하기 위해, 프레임워크 기반의 한글 자연어 처리 챗봇 성능 향상을 위한 점진 학습(Incremental Learning)을 제안한다. DialogFlow는 규칙 기반의 챗봇 프레임워크로서, 사용자 질의 패턴에 대한 사전 학습이 치명적이다. 제안하는 점진 학습 기법은 사용자 질의가 미리 학습되어 있지 않은 경우에도, 유사도 기반으로 질의의 의도를 결정할 수 있다. 이때 entity 조합과 기존에 학습된 질의들과의 유사도를 통해 의도를 결정하여, 프레임워크를 점진적으로 학습한다. 이를 적용하여 연세대학교 정보들을 제공하는 챗봇을 개발하고, 실험을 통해 제안된 점진 학습 기법은 기존 시스템보다 다양한 종류의 질의 처리가 가능하고, 더욱 빠른 응답 속도를 나타내는 것을 확인하였다. 또한 사용자가 증가함에 따라 점진 학습을 통해 성능이 더욱 증가하는 자가 학습 모형으로서의 우수함을 확인하였다.

This study endeavors to delineate the essential components of digital preservation policies requisite for data repositories. Drawing from an examination of digital preservation policies from data repositories accredited by CoreTrustSeal in 2023, this study unveils the pivotal components intrinsic to a digital preservation policy framework, subsequently elucidating the content each component encompasses. The proffered framework is anticipated to serve as a foundational reference for institutions aiming to craft their digital preservation policies, transcending the confines of those solely pursuing CoreTrustSeal certification, to encompass both domestic and international institutions irrespective of their intent to seek CoreTrustSeal certification.
