인터넷과 통합된 멀티미디어 기술의 발전 및 초고속 통신망의 보편적인 사용으로 인해 유기적으로 통합된 멀티미디어 컨텐츠에 대한 웹 서비스의 필요성이 대두되었다. 이에 따라 1998년 W3C(World Wide Web Consortium)에서 제안된 XML(eXtensible markup Language) 기반의 통합 멀티미디어 표현 언어인 SMIL(Synchronized Multimedia Integration Language) 1.0이 발표되었고, 기능이 확장되어 2000년 9월 SMIL 2.0으로 최종 Working Draft안이 발표되었다. 본 논문에서는 웹 컨텐츠 제공자 및 개인 사용자에게 SMIL 컨텐츠 저작을 위한 자동 생성 모듈 및 전용 저작 도구를 제공하고, SMIL 컨텐츠 데이터베이스 서버 및 재생기와의 통합으로 원활한 SMIL 컨텐츠 서비스 환경을 제공하는 통합 멀티미디어 시스템의 설계 및 구현을 제시하였다.

인터넷 표준 문서인 XML(Extensible Markup Language)이 구조적인 내용만을 갖고 있기 때문에 문서를 보여주기 위한 표현 정보를 포함하는 스타일 시트(style sheets)가 필요하다. 이를 위해 W3C(World Wide Web Consortium)에서는 XML 문서의 구조적인 접근을 위한 XPath(XML Path Language)와 문서의 내용구조를 변환하기 위한 XSLT (Transformations), 그리고 포맷팅 정보를 위한 XSL-fo(XSL Formatting objects)로 구성되는 XSL(Extensible Stylesheet Language)를 제안하였다. 본 논문에서는 XML 문서와 XSL 스타일 시트를 이용하여 XML 문서의 데이터를 변환하고 XSL-fo 정보를 이용하여 결과 FO(Formatting Objects)를 생성한다. 또한 트리로 구성된 결과 FO에서 페이지 정보와 FOT (Formatting Objects Tree)를 추출하는 FOT 생성부를 두었고, 디스플레이 관리기와 포맷팅 모듈 객체 관리기를 두어 FOT를 포맷팅을 위한 모듈로 저장하고 디스플레이 해주는 포맷팅 처리 시스템을 설계 및 구현하였다.

LabVIEW is faster than text language based program regarding development time and can monitor the output of data fast without the separate compiling work as the graphic-based graphical programming language. And, its coding is fast because it is designed by connecting the function with the wire and its has the merit of relatively intuitive UI. In this paper, data transmission and receiving between the program that is implemented in C language as CAN communication method that is strong against noise and used in power electronics application field variously and LabVIEW based program are explained. And, the design of LabVIEW based CAN communication program, data analysis and GUI screen composition that is convenient for monitoring are shown.

Crop growth simulation models have been developed as research and management tools. When these models are needed to incorporate new knowledge on phenology and physiology of crops, programming languages have been used for development and documentation of these models. However, researchers may have limited skill in programming languages. Furthermore, software developer may find it challenging to improve the crop models because documentation of the models are rarely available. The Unified Modeling Language (UML) can provide a simple approach for development and documentation of model. A template for implementation of the model can be obtained using the UML, which would facilitate code re-use and model improvement.

수화는 농인 사회에서 주로 사용되는 시각언어로서 음성언어인 한국어와 통사적인 측면에서 많은 차이를 보인다. 특히 수화에서는 조사와 어미가 거의 사용되지 않기 때문에 한국어 문장에서 기존의 방법대로 이들을 제거한 후 어순을 고려하지 않은 채 문장 성분의 기본형을 그대로 나열하여 수화문을 생성할 경우 문장 성분 간의 통사적 관계가 애매해질 수 있다. 본 논문에서는 통사적 중의성이 한국어 문장을 수화문으로 변환하는 과정에서 추가적으로 나타나게 되는 특정 통사구조에 의해 발생하는 것으로 보고, 이러한 통사구조를 기본논항구조, 한정수식구조, 병렬구조, 서술구조로 분류하여 각각을 파악하고 그에 따라 통사적 중의성을 해소하는 방법을 제시한다.

In this paper, a hardware compiler for symbolic description language(SDL) is proposed for logic design automation. Lexical analysis is performed for SDL which describes the behavioral characteristics of a digital system at the register transfer level by the proposed algorithm I. The algorithm I is proposed to get the expressions for the control unit and for the data transfer unit. In order to obtain the network description language(NDL) expressions equivalent to gate-level logic circuits, another algorithm, the the algorithm II, is proposed. Syntax analysis for the data formed by the algorithm I is also Performed using circuit elements such as D Flip-Flop, 2-input AND, OR, and NOT gates. This SDL hardware compiler is implemented in the programming language C(VAX-11/750(UNIX)), and its efficiency is shown by experiments with logic design examples.

This paper introduces the technological development trends in on-device SLMs (Small Language Models). Large Language Models (LLMs) based on the transformer model have gained global attention with the emergence of ChatGPT, providing detailed and sophisticated responses across various knowledge domains, thereby increasing their impact across society. While major global tech companies are continuously announcing new LLMs or enhancing their capabilities, the development of SLMs, which are lightweight versions of LLMs, is intensely progressing. SLMs have the advantage of being able to run as on-device AI on smartphones or edge devices with limited memory and computing resources, enabling their application in various fields from a commercialization perspective. This paper examines the technical features for developing SLMs, lightweight technologies, semiconductor technology development trends for on-device AI, and potential applications across various industries.

High-level synthesis (HLS), which automatically synthesizes a register-transfer level (RTL) circuit from a behavioral description written in a high-level programming language such as C/C++, is becoming a more popular technique for improving design productivity. In general, HLS tools often generate a circuit with a larger area than those of hand-designed ones. One reason for this issue is that HLS tools often generate multiple instances of the same module from a function. To eliminate such a redundancy in circuit area in HLS, HLS tools are capable of sharing modules. Function-level module sharing at a behavioral description written in a high-level programming language may promote function reuse to increase effectiveness and reduce circuit area. In this paper, we present two HLS techniques for module sharing at the function level.

In this paper, we describe the implementation of Bluetooth headset. Bluetooth headset sets up link using ACL connection between headset and audio gateway, transfers 64kbps voice using SCO connection. Bluetooth headset implemented in this paper is designed with no HCI, so all protocol stack is implemented in Bluetooth module. We verify the upper layer protocol and application program using C-language modeling on Unix environment.

The purpose of this study is to present a new function point estimation approach for the Object-Oriented information systems. In order to fulfill this purpose, we first review the literature on Function Point Analysis of IFPUG, Unified Modeling Language, and Unified Process. Then, we derive a method and rules for estimating Function Points based on Use Cases and Class Diagrams. To analyze the appropriateness of the proposed approach, we conduct the empirical testing. 143 use cases are collected from production, marketing, distribution, sales, and other areas from the Object-Oriented systems development projects. We compare our new approach with the existing methods that are usually used for traditional systems development projects. The results show that our proposed approach is more appropriate for the Object-Oriented environment.
