Uniview system is a client-server system that runs on heterogeneous distributed systems and supports the debugging of various kinds of programs. Its client system provides a unified debugging concept and interface on various debuggers of heterogeneous hosts. Its server system provides debugging services and features openness and scalability by interoperating with one or more debugger processes existing on the same host. Based on FSF(Free Software Foundation)'s gdb and Sun Microsystems's dbx. Uniview system supports C/C++ programming language in various UNIX environments as well as Windows environments. The proposed system was designed and implemented to support the JAVA language, which is prevalently used in recent heterogeneous distributed systems and was partly extended to make a clear analysis of JAVA class file structure. Sun Microsystems's Jdb supplied as a JAVA debugger has very limited functions compared to other programming language debugger. In this paper, Uniview as a JAVA debugging system was implemented to provide debugging technologies which are necessary to debug Java applications but missing in current JAVA language as well as to provide its users with various information.

This study proposes a Natural Language Query Framework (NLQF) for the semantic web. It supports an intelligent inference at a semantic level. Most of previous researches focused on the knowledge representation on the semantic web. However, to revitalize the intelligent e-business on the semantic web, there is a need for semantic level inference to the web information. To satisfy the need, we will review the knowledge/resource representation on the semantic web such as RDF, Ontology and Conceptual Graph (CG), and then discuss about the natural language (NL) inference. The result of this research could support a natural interface for the semantic web. Furthermore, we expect that the NLQF can be used in the semantic web-based business communications.

This study examines the influence of early English education on children's bilingual language development to see whether the early exposure to English education affects children's competencies of both English and Korean. Based on this purpose, it attempts to examine whether it supports additive or subtractive bilingualism. The competencies of both English and Korean of the children with early English education were, therefore, compared with those of the children without it, and the relation between the two competencies was also studied. For this research, two different groups of children - one with 48 children who attend English kindergarten and the other with 60 children who attend only Korean kindergarten - took PPVT-R in Korean and in English each. The result shows that children with early English education have more English competency than those without it. No significant differences, however, are found in Korean competency between the two groups. The relation between the two competencies proves positive in children with early English education. It can thus be concluded that the effect of early English education is partially positive on children's language development, which may support the additive bilingualism that children's second language can improve without losing their native language competency. In addition, this result will be able to provide for us the direction and the guideline to the policy of foreign language education and early education.

Tourism and hospitality have encountered significant changes in recent years as a result of the rapid development of information technology (IT). Customers now expect more expedient services and customized travel experiences, which has intensified competition among service providers. To meet these demands, businesses have adopted sophisticated IT applications such as ChatGPT, which enables real-time interaction with consumers and provides recommendations based on their preferences. This paper focuses on the AI support-prompt middleware system, which functions as a mediator between generative AI and human users, and discusses two operational rules associated with it. The first rule is the Information Processing Rule, which requires the middleware system to determine appropriate responses based on the context of the conversation using techniques for natural language processing. The second rule is the Information Presentation Rule, which requires the middleware system to choose an appropriate language style and conversational attitude based on the gravity of the topic or the conversational context. These rules are essential for guaranteeing that the middleware system can fathom user intent and respond appropriately in various conversational contexts. This study contributes to the planning and analysis of service design by deriving design rules for middleware systems to incorporate artificial intelligence into tourism services. By comprehending the operation of AI support-prompt middleware systems, service providers can design more effective and efficient AI-driven tourism services, thereby improving the customer experience and obtaining a market advantage.

The paper proposed a basic architecture of an agent system to support exchange and sharing of design informations by means of ACL(Agent Communication Language) which can represent design informations and knowledges. Based on the architecture of the agent system a ship initial design agent system was implemented in order to show the effectiveness of the agent-based system. The basic architecture of the agent consists of an ACL handlerand CORBA(Common Object Request Broker Architecture) objects for the exchange of ACL messages in the heterogeneous and distributed environment. The ACL handler can process expressions of knowledge and manage communication messages among the agents. The paper mainly focuses on the implementation of the ACL handler. The ACL handler consist of a KQML(Knowledge Query and Manipulation Language) handler that manages KQML messages, a conversation module, and a content handler that handles message contents. The conversation modulo implements conversation policies and checks all messages if they are allowable and meaningful messages based on the conversation policies. The implemented agent-based system was applied to the ship initial design to show the handling procedure of the agent system.

The Grid system is an emerging computing infrastructure that will substitute for existing distributed systems. However end users have a difficulty in using the Grid because of its complicated usage, which is an inherent characteristic from the heterogeneous mechanism of the Grid. In this paper, we present the JCML(Job Control Markup Language) and its GUI-based editor, which not only provide users with ease of use, improved working environment, but assist users to execute their jobs efficiently The JCML is a job control language that improves the RSL of Globus, which defines global services in Grid. The JCML is designed to support flexibility among various Grid services using standard XML. And it makes use of a graph representation method, GXL(Graph eXchange Language), to specify detailed job properties and dependencies among jobs using nodes and edges. The JCML editor provides users with GUI-based interface. With the JCML editor, a complicated job order can be easily completed using very simple manipulations with a mouse, such as a drag-and-drop.

In this study, we studied the influence that the stress placed on children (originating from presence of two cultures at multi-cultural families) can have on adapting to school, and further assessed the control effect of teachers' support as a protection factor. In order to achieve the goal of the research, we identified samples of children between Grades 3-6 who came from multi-cultural families to carry out surveys. Based on the results of our analysis, the experience of discrimination and language conflicts experienced by children from multi-cultural families affected their academic activities (among adaptation factors to school experiences), while teachers' support appeared to have a control effect. However, for the influence of language conflicts on friend relationships (among adaptation factors to school experiences), teachers' support did not have a control effect. As such, based on this research result, we've proposed plans to improve school adaptation of children from multicultural families.

Rhetorical relations between two text fragments are essential information and support natural language processing applications such as Question - Answering (QA) system and automatic text summarization to produce an effective outcome. Question - Answering (QA) system facilitates users to retrieve a meaningful response. There is a demand for rhetorical relation based datasets to develop such a system to interpret and respond to user requests. There are a limited number of datasets for developing an Arabic QA system. Thus, there is a lack of an effective QA system in the Arabic language. Recent research works reveal that unsupervised learning can support the QA system to reply to users queries. In this study, researchers intend to develop a rhetorical relation based dataset for implementing unsupervised learning applications. A web crawler is developed to crawl Arabic content from the web. A discourse-annotated corpus is generated using the rhetorical structural theory. A Naïve Bayes based QA system is developed to evaluate the performance of datasets. The outcome shows that the performance of the QA system is improved with proposed dataset and able to answer user queries with an appropriate response. In addition, the results on fine-grained and coarse-grained relations reveal that the dataset is highly reliable.
