  • In this paper, several problems functioning as the obstacles against software reuse were summarized. Among them, the issues dealt with in this paper include the effective method for constructing the library, the proper structure of the library, and the efficient retrieval technique. The knowledge-based approach and the information retrieval approach were integrated to construct and manage the library. The former is on the object- oriented model. Basically the object-oriented library is based on the classes and organized by inheritance. Because inheritance hierarchy is based on syntactical information, it dose not present the relationship of functionality. Using the information retrieval approach, the index file which characterizes the component and similarity among the components can be analyzed. Especially, we focused on the reusable library for the object-oriented programming environments.

  • Chinese society, which maintained the feudal social system, has taken an isolationist policy in response to the Western aggression since $20^{th}$ century. However, in the wake of the Opium War of 1840, China had actively accepted Western culture, not in just politics and economy, but in diverse area of social property. Since these process, the modernization of China had begun and the Chinese museum has been erected and evolved through the process of it. And it can be deducted that the philosophy of socialist society had a considerable influence on the spatial configuration of the Chinese museum since it was at the heart of china's modernization. And another social shift has been made since 2000 that is regarded as the internationalization of China. It brought a new point of de-structuralism to the society since 2000 and it is leading the changes of various areas of culture and arts, including museology in Chinese society. The purpose of this study is to understand what changes have been made to the museums in China since 2000 and how the internationalization of China is engaged with this it, in terms of the spatial structure of a museum. To do this the study examined the spatial changes of the museum in the mathematical approach including Space Syntax tool and it was engaged with the changes of museum type. Throughout the study, it was concluded that spatial structure of museums in china has been changed from structural organization to de-structural one since 2000 of China's internationalization.

  • SGML, defined as the ISO 8879, is a meta-language to define a document type, used as basic format for electronic documents. Since an SGML document is composed of a document type definition and a document instance conforms to the definition, it is necessary for SGML document authoring tools to compose and validate document type and document instance. In present, formal models and procedures for SGML documents are not defined, it's not easy to construct such tools. We propose a model of SGML authoring tool consists of SGML parser, document type definition editor, SGML document editor and style editor. We also introduce and implement formal procedure for each component. For user convenience, we adopted icon based visual programming method, and solved the HANGUL problems. The SGML authoring tool is implemented I Windows NT system using java and C++ programming language.

  • Variable Message Format(VMF) is a communications protocol that allows computers to exchange tactical military information over low-data-rate bearers. VMF is designed to define message length and structure variably in order to allow the user to transmit only the relevant information by using indicators. However, flexibility of messages makes it difficult to analyze messages structure and figure out meanings. Furthermore, whenever messages are added or modified, message processing software should be updated and distributed to systems. In this paper, we propose a systematic approach to defining VMF messages that uses the international standard notation ASN.1. By describing VMF messages in ASN.1, protocol architects can deal with VMF messages accurately and conveniently, and use various ASN.1 tool. This paper develops ASN.1 description templates for VMF message segments, and presents an approach to describing VMF messages in ASN.1 by combining the templates.

A Study on the Part of Speech of 'Perfect' Marker 'YOU(有)' - The part of speech of 'YOU(有)' in the question 'YOUMEIYOU(有没有)+VP?' (완료상표지 '유(有)'의 품사자질 연구 - '유몰유(有没有)+VP?'구조를 중심으로)

  • The question 'YOUMEIYOU(有没有)+VP?' indicating 'Perfect' was mainly used in the Southern Chinese dialect, recently this question 'YOUMEIYOU(有没有)+VP?' has also been widely used in Mandarin. In the academic world, it is reported that the appearance of 'YOUMEIYOU(有没有)+VP?' was influenced by the Southern Chinese dialect. However, there are divergent opinions about the part of speech of 'YOU(有)', such as 'auxiliary verb' , 'adverb' , 'verb', and 'particle' etc,, and these are classifiable into two main theories-'auxiliary verb' theory and 'adverb' theory. In this paper, we considered the validity of these two theories in terms of syntactic, semantic, diachronous, and typological. The results are as follows. First, based on the prototype category theory, we reclassified typical syntactic and untypical syntactic features of 'auxiliary verb' and 'adverb'. Through this, we considered the syntactic features of 'YOU(有)' are closer to the syntactic features of either of the two. As a result, It is reasonable to think that '有(YOU)' is an 'adverb' that has untypical syntactic features (It is 'adverb', but can constitute a positive-negative question, such as 'ZAIBUZAI(再不再)', 'CHANGBUCHANG(常不常)', 'CENGBUCENG(曾不曾)' and so on.). Second, the semantic features of 'YOU(有)' in the question 'YOUMEIYOU(有没有)+VP?' indicates 'Aspect' meaning ('Perfect'), does not indicate the 'Modality' meaning represented by the general 'auxiliary verb'(ability, will, deontic, epistemic etc.). Unlike English, contemporary Mandarin does not have a separate form of 'auxiliary verb'(have, be) that represents 'Modality' and 'Aspect'. On the other hand, it is reasonable to consider 'You(有)' as an 'adverb', because 'adverb' has played a role of 'Aspect' meaning(Ceng(曾), Yi(已), Zai(在), Yao(要) etc.) from the pre-QIN(先秦) dynasty before the appearance of 'Perfect particle' '了'. Third, in the Chinese history and grammar academic world, the prevailing view is that 'MEIYOU(没有)' which began to appear in front of VP in Ming(明) dynasty is regarded as a 'negative adverb'. Therefore, if 'MEIYOU(没有)' in the question 'YOUMEIYOU(有没有)+VP?' is regarded as a 'negative adverb', it is not reasonable to regard the remaining '有(YOU)' as an auxiliary verb. Also, there are some examples of 'You(有)' written as an 'adverb' in the pre-QIN(先秦) dynasty, so it is reasonable to regard '有(YOU)' as an 'adverb'. Fourth, according to the study of the linguistic typological theory, the 'H-POSSESSIVE' verb was grammaticalized toward 'Perfect' marker in many languages around the world. However, after this grammaticalization the part of speech is not all 'auxiliary verb'. In some languages, they can be grammaticalized toward 'adverb'. Therefore, it is reasonable to regard '有(YOU)' as an 'adverb'.

  • The writings frame and various rules based on discourse structure and knowledge-based methods were applied to construct the automatic Ext/sums (extracts & summaries) system from the straight news in web. The frame contains the slot and facet represented by the role of paragraphs, sentences , and clauses in news and the rules determining the type of slot. Rearrangement like Unification, separation, and synthesis of the candidate sentences to summary, maintaining the coherence of meanings, was carried out by using the rules derived from similar degree measurement, syntactic information, discourse structure, and knowledge-based methods and the context plots defined with the syntactic/semantic signature of noun and verb and category of verb suffix. The critic sentence were tried to insert into summary.

  • In each industry field, many engineers have tried to develop integrated environments using information technology. The core technology in building integrated environments is the database based on standardized information. To meet the requirements, this study builds a database with detailed design information as a part of integrating digital information generated from every work of steel bridges. The data model used to build the database was developed based on the international standard, namely ISO/STEP. The data model is classified into geometric and non-geometric parts to represent the design information of steel bridges. The geometric parts are represented by a three dimensional solid model so that they may be able to reuse existing information. Also, the non-geometric parts represent information requirements that are analyzed by the development method of standard data model. To verify the data model, this study validates the syntax of the model on EXPRESS Engine and verifies the validation of the model by applying the design data of Hannam bridge to the database.

  • The software Process can be defined as the set of activities, rules, procedures, techniques and tools used within the production of software. A software process model is a conceptual representation of a real world software Process and can be described by process programming languages. In this paper, we present the language constructs of SimFlex designed for object-based software process programming. The design of SimFlex is based on the object concept, so that it can model complex software processes concisely both in syntax and semantics. Since the language constructs of SimFlex are derived from the analysis of major PSEEs and their associated process programming languages, SimFlex includes the core characteristics required for a desirable object-based process programming language. In addition, SimFlex is designed to act as a template software process definition language which could be included in specific PSEEs through customization appropriate to those PSEEs.
