In this paper, we develope a stock trading system that automatically buy and sell stocks in Kiwoom Securities' HTS system. The system is made by using Kiwoom Open API+ with the Python programming language. A trading strategy is based on an enhanced system query method called a Condition-Search. The Condition-Search script is edited in Kiwoom Hero 4 HTS and the script is stored in the Kiwoom server. The Condition-Search script has the advantage of being easy to change the trading strategy because it can be modified and changed as needed. In the HTS system, up to ten Condition-Search scripts are supported, so it is possible to apply various trading methods. But there are some restrictions on transactions and Condition-Search in Kiwoom Open API+. To avoid one problem that has transaction number and frequency are restricted, a method of adjusting the time interval between transactions is applied and the other problem that do not support a threading technique is solved by an IPC(Inter-Process Communication) with multiple login IDs.

The Call Processing Language (CPL, in short), recommended in RFC 2824 of IETF, is a service description language for the Internet Telephony. The CPL allows users to define their own services, which dramatically improves the choice and flexibility of the users. The syntax of the CPL is strictly defined by DTD (Document Type Definition). However, compliance with the DTD is not a sufficient condition for correctness of a CPL script. There are enough rooms for non-expert users to make semantical mistakes in the service logic, which could lead to serious system down. In this paper, we present six classes of semantic warnings for the CPL service description: MF, IS, CR, AS, US, OS. For each class, we give the definition and its effects with an example script. These warnings are not necessarily errors. However, these warnings will help users to find ambiguity, redundancy and inconsistency in their own service description.

A network-based robot [1] is a robot that explores service servers in the network environment for analyzing sensor data and making decision. Since network-based robot architecture was proposed, it's possible to reduce costs of robots. We hope robots would be all around at home environment. Therefore, normal users who are not experts need to be able to control those robots by using easy commands. We developed a scripting language, named CCSLR, to help users and developers who control various robots in ubiquitous environment. We focused on how to design the common language for various robots and how to translate a CCSLR script into a sequence of low-level commands of the target robot. In this paper, we propose scripting methods, with three layers. The CCSLR system reads the profile information from the knowledge representation database. Users don't have to know all about kinematical and mechanical details of a robot. Then again, the CCSLR system will use the profile information to translate the script into separated executable library commands. The CCSLR system manages robot's changing state every time a robot executes a command.

HTML revolutionized the way we specify the appearance of data on the Internet. Today, XML (the eXtensible Markup Language) is changing the way we specify the meaning of data. XML, lets document authors define their own markup tags and attribute names to assign meaning to the data elements in the document. Further, XML elements can be nested and include references to indicate data relationships, as Listing One. Unlike HTML, XML markup tags do not describe how to render the data. Rather, they provide descriptions of data, allowing software to understand the meaning of the data automatically For publishing, instead, XSL, the eXtensible Stylesheet Language as a separate language , is in charge of specifying the presentation of XML documents. The purpose of this study is to discover how to transform your organizations relational data into potential e-commerce, business-to-business, and web application with XML and XSL documents. For this purpose, the literature survey, first of all, was undertaken to understand the basic structures of XML documents. Second, one case implementation was performed to understand how to transform Access 2002 XML Files into HTML with XSLTand VB script. The results come out to be successful, more or less. But the limitations of it still exist. One immediate limitation is that XML documents are essentially tree structure, as dictated by the nesting of elements. However, relational database tables are two dimensional matrix structure. In addition, real-world data often is graph structured-a single data element may be referenced in multiple ways. However, this study is useful for understanding how to convert relational database into XML documents and to publish them using XSL or VB script.

In future telecommunications systems, behaviour will be defined by inexperienced users for many different purposes, often by specifying requirements in the form of policies. The call processing language (CPL) was developed by the IETF in order to make it possible to define telephony policies in an Internet telephony environment. However, user-defined policies can hide inconsistencies or feature interactions. In this paper, a method and a tool are proposed to flag inconsistencies in a set of policies and to assist the user in correcting them. These policies can be defined by the user in a user-friendly language or derived automatically from a CPL script. The approach builds on a pre-existing logic programming tool that is able to identify inconsistencies in feature definitions. Our new tool is capable of explaining in user-oriented terminology the inconsistencies flagged, to suggest possible solutions, and to implement the chosen solution. It is sensitive to the types of features and interactions that will be created by naive users. This tool is also capable of assembling a set of individual policies specified in a user-friendly manner into a single CPL script in an appropriate priority order for execution by telecommunication systems.

We have been studying the next generation of video creation solution based on TVML (TV program Making Language) technology. TVML is a well-known scripting language for computer animation and a TVML Player interprets the script to create video content using real-time 3DCG and synthesized voices. TVML has a long history proposed back in 1996 by NHK, however, the only available Player has been the one made by NHK for years. We have developed a new TVML Player from scratch and named it T2V (Text-To-Vision) Player. Due to the development from scratch, the code is compact, light and fast, and extendable and portable. Moreover, the new T2V Player performs not only a playback of TVML script but also a Text-To-Vision conversion from input written in XML format or just a mere plane text to videos by using 'Text-filter' that can be added as a plug-in of the Player. We plan to make it public as freeware from early 2009 in order to stimulate User-Generated-Content and a various kinds of services running on the Internet and media industry. We think that our T2V Player would be a key technology for upcoming new movement.

본 연구는 3~6세의 언어장애아동을 대상으로 일상적 스크립트를 활용한 언어중재에서 양육자와 언어재활사가 인식하는 우선적 중재가 필요한 주요 의사소통 상황을 분석하는데 목적이 있었다. 예비조사와 본 설문조사를 거쳐 수집한 데이터를 계층분석 (AHP)을 사용하여 분석하였다. 그 결과, 3개의 상위 상황 중에서 양육자는 '교육사회생활' 그리고 언어재활사는 '가정생활'을 가장 우선적인 상황으로 선택하였다. 상위별 하위상황의 경우, '가정생활'에서는 '식사', '교육사회생활'에서는 '친구와 놀기'가, 그리고 '여가문화생활'에서는 '놀이터'가 중요한 의사소통 상황으로 인식되었다. 전체 35개의 하위 상황에서 양육자는 '친구와 놀기' 그리고 언어재활사는 '식사'를 선택하였으며, 상위 5순위의 상황을 살펴보면 양육자와 언어재활사 모두 '가정생활'의 상황들이 높은 중요도 비율을 보였다. 아동연령별로 양육자 인식을 분석한 결과, 3세와 6세의 각 양육자 집단은 '가정생활' 그리고 4세와 5세의 각 양육자 집단은 '교육사회생활'을 가장 중요한 상위 상황으로 보았다. 전체 하위상황에서도 아동의 연령별로 양육자의 주요 상황에 대한 우선순위 인식에서 약간의 차이를 보였다. 본 연구결과는 언어재활사가 스크립트를 활용한 언어중재를 실시할 때 아동의 연령과 발달수준 뿐만 아니라 양육자의 요구를 고려한 의사소통 상황의 선정이 필요함을 시사한다.

This study focused on the comprehension of texts written either in Korean script (Hangul) or Chinese script (Hanja). For this purpose, we measured the reading time and the correct response in text comprehension tasks with 104 Korean-Chinese children who were either 10 or 19 years old. There was a main effect of script : The reading time of Hanja texts was shorter than that of Hangul or Hangul Hanja mixed texts. But the older subjects who spent the same reading time in both Hangul and Hanja texts showed the longer reading time in Hangul Hanja mixed texts revealing the interaction between age and script. The correct response rate on the comprehension task was the highest in Hangul text. The results were discussed in relation to the independent dual language processing systems in Korean-Chinese.

최근 SW 교육의 관심이 증대되고 프로그래밍 교육이 대학 학부교육의 주요한 부분으로 인식되고 있다. 특히 프로그래밍 입문 도구로서 블록 기반 프로그래밍 도구가 널리 사용되고 있으며 프로그래밍 입문자에게 기존 프로그래밍 언어와 비교하여 매우 다양한 장점들을 제공하고 있다. 한편 블록기반 프로그래밍 도구로 작성된 코드가 스크립트 언어일 경우 스크립트의 품질과 수준을 정교하게 측정하기 위해서는 상당한 노력을 기울어야 한다. 따라서 블록기반 프로그래밍 코드의 품질측정과 관련된 대부분의 연구는 단순히 프로그래밍 개념과 연관된 블록의 사용개수를 정량화하여 스크립트의 수준을 평가하고 있다. 그 결과 기존연구의 기법으로는 취약수준을 측정하거나 스크립트에 명시되지 않는 프로그래밍 개념에 대한 평가가 어렵다. 본 연구는 블록기반 프로그래밍 스크립트의 품질측정 및 취약수준 분석이 가능한 프레임워크를 제안한다. 프레임워크에서는 블록기반 프로그래밍 언어들이 내포한 다양한 프로그래밍 개념을 구조화한 평가 매트릭스를 구축하고 동 지표를 기반으로 스크립트의 품질 측정과 항목별 취약점 개선에 따른 수준향상 모델을 제안함으로써 개인별 수준진단 및 향후 개선 가능한 목표수준을 예측할 수 있도록 하였다.
