This paper describes TVML (TV program Making Language) for automatically generating television programs from text-based script. This language describes the contents of a television program using expression with a high level of abstraction like“title #1”and“zoom-in”. The software used to read a script written in TVML and to automatically generate the program video and audio is called the TVML Player. The paper begins by describing TVML language specifications and the TVML Player. It then describes the“external control mode”of the TVML Player that can be used for applying TVML to interactive applications. Finally, it describes the TVML Editor, a user interface that we developed which enables users having no specialized knowledge of computer languages to make TVML scripts. In addition to its role as a television-program production tool. TVML is expected to have a wide range of applications in the network and multimedia fields.

자바스크립트는 현재 웹 사이트, 웹 어플리케이션에서 가장 많이 사용되는 스크립트 언어 중 하나이다. 자바스크립트로 작성된 프로그램은 원본 프로그램 형태로 클라이언트에게 전송되므로 무단 복제, 도용에 쉽게 노출된다. 때문에 자바스크립트 프로그램의 도용을 탐지하기 위한 연구가 필요하다. 현재 일반적으로 프로그램 표절 탐지를 위해 사용되는 자동화 도구들의 경우 고수준의 표절 기법에 적절히 대응하지 못한다. 반면에 프로그램 종속성 그래프에 기반을 둔 기존 연구들의 경우 자바스크립트의 동적인 특징을 적절히 반영하지 못한다. 또한 지나친 일반화로 인해 일부 틀린 판정(false positive)을 보이며 대상 프로그램의 크기가 클 경우 탐지 속도에 문제를 보이고 있다. 본 논문에서는 자바스크립트에 특화된 프로그램 종속성 그래프(이하 JS PDG)와 이를 사용한 도용 탐지 기법을 제안하여 이러한 문제를 해결하고자 한다. 본 논문에서 제안하는 JS PDG는 세분화된 노드 타입을 가지고 있어 기존 PDG와 비교해 보다 정확한 그래프 간 비교를 할 수 있도록 하며 포함하고 있는 노드 타입에 따라 정의되는 JS PDG의 타입은 탐색 범위를 분할을 가능하게 해 전체 도용 탐지 속도가 개선 될 수 있도록 한다. 실험 결과 기존 PDG에서 나타나는 틀린 판정을 확인할 수 있었으며 PDG간 비교 횟수가 줄어들어 도용 탐지 속도가 개선됨을 확인할 수 있었다.

자바스크립트 프로그램의 많은 경우가 이벤트 중심의 프로그램(event-driven program)으로, 사용자의 입력을 받아 실행하는 이벤트 함수를 매우 많이 사용한다. 따라서, 이벤트 중심의 자바스크립트 프로그램을 정적으로 분석하려면 이벤트가 어떻게 발생하고 동작하는 지를 분석할 수 있어야 한다. 본 논문에서는 자바스크립트 프로그램에서 이벤트의 발생과 동작을 정적으로 정확하게 분석하기 어려운 이유를 확인하고, 이벤트 중심 프로그램을 효과적으로 분석하기 위해 이벤트를 효율적이고 정확하게 나타낼 수 있는 이벤트 모델 기법을 제시한다.

Recently, factory automation and shop floor control system need a web based remote monitoring technology to control effectively machine tool. This paper describes a web based remote monitoring system which is concerned with open architecture controller for machine tool. The environment of this system consists of a lot of elements such as web server, database, machine tool, pc based controller, client computers and script programs, also which is interconnected by network including intranet or internet. Designed script programs, also which is interconnected by network including intranet or internet. Designed script program service current status and faults information of machine to remote users who want to monitor machine tool. Additionally those have various functions to service we board for q&a, downloading data and information of after-service managers.

With the advent of PyScript, there are more and more topics in practice. However, the official guideline has not provided a detailed description. This paper investigates the practical application about PyScript. The research results show that the current functions in PyScript cannot be well handled in web pages, and even cannot use the advantage model of Python, which is not suitable for practical application in the short term. However, it may be widely used in web development in the future since writing functions through Wasm can improve the efficiency of program execution.

Recently, many malicious users have attacked web browsers using JavaScript code that can execute dynamic actions within the browsers. By forcing the browser to execute malicious JavaScript code, the attackers can steal personal information stored in the system, allow malware program downloads in the client's system, and so on. In order to reduce damage, malicious web pages must be located prior to general users accessing the infected pages. In this paper, a novel framework (JsSandbox) that can monitor and analyze the behavior of malicious JavaScript code using internal function hooking (IFH) is proposed. IFH is defined as the hooking of all functions in the modules using the debug information and extracting the parameter values. The use of IFH enables the monitoring of functions that API hooking cannot. JsSandbox was implemented based on a debugger engine, and some features were applied to detect and analyze malicious JavaScript code: detection of obfuscation, deobfuscation of the obfuscated string, detection of URLs related to redirection, and detection of exploit codes. Then, the proposed framework was analyzed for specific features, and the results demonstrate that JsSandbox can be applied to the analysis of the behavior of malicious web pages.

A web application running on the Internet is causing many difficulties for a program developer, and it requires to process multiple sessions at the same time due to the occurrence of excessive traffic. Web applications should be able to process concurrent requests efficiently and in real time. Node.js is a single-threaded server-side JavaScript environment implemented in C and C ++ as one of the latest frameworks to implement event models across the entire stack. Nodes implement JavaScript quickly and robust to achieve the best performance using a JavaScript V8 engine developed by Google. In this paper, it will be explained the operation principle of Node.js, which is a lightweight real-time web server that can be implemented in JavaScript for real-time responsive web applications. In addition, this application was practically implemented through automatic alignment system for group scheduling to demonstrate event-based real-time response web processing.

In recent years, Unreal Engine has been increasingly included in the animation process produced in the studio. In this case, there will be more than one of main software, and it is very important to accurately transfer data between the software and Unreal Engine. In animation data, not only the animation data of the character but also the animation data of objects interacting with the character must be individually produced and transferred. Most of the objects that interact with the character have a condition of constraints with the part of character. In this paper, I tried to stipulate the production process for extracting animation data of constrained objects, and to analyze why users experience difficulties due to the complexity of the regulations in the process of executing them. And based on the flowchart prescribed for user convenience, I created a program using a Python script to prove the user's convenience. Finally, by comparing the results generated according to the manual flowchart with the results generated through the script command, it was found that the data were consistent.

The Monte Carlo (MC) method has become an indispensable part of the nuclear radiation research field. Several widely used and well-known MC packages were developed for simulation of radiation transport and interaction with matter. All these MC packages require users to prepare an input script. The input script can become lengthy for complex models. The process of preparing these input scripts is time-consuming and error-prone. In the present work, we have developed an open-source GUI computer program for modelling radiation transport and interaction in multi-segmented slab phantoms using grid-based system for the widely used PHITS MC package. The developed tools would be useful for future users of PHITS MC package and particularly inexperienced users. The present program is distributed under GPL license and all users can freely download, modify and redistribute the program without any restrictions.

상황인식 처리기술을 위한 응용 소프트웨어를 개발하기 위해서는 다양한 상황인식에 대한 판단과 그에 따른 적절한 처리를 모두 프로그램 언어로 기술해야 하며, 이는 무수한 프로그램 코드의 반복과 소프트웨어 생산성의 저하를 초래한다. 따라서 본 논문에서는 상황인식을 위해 요구되는 일련의 복잡한 과정을 간략하고 명료하게 기술하고 상황에 대한 정의를 미리 규격화된 구문으로써 표현함과 동시에 자동적으로 처리할 수 있는 상황인식을 위한 컨텍스트 스크립트 언어 및 언어 처리기를 구현한다. 제안하는 컨텍스트 스크립트 언어는 주어진 상황을 효율적으로 정의 할 수 있는 기능을 제공함은 물론 보다 다양한 상황을 범용적으로 표현할 수 있도록 설계한다. 아울러 제안하는 언어 처리기의 유용성을 보이기 위해, 상황인식에 근거하여 음악 재생 서비스를 제공하는 응용 시스템을 구축한다.
