Currently many non-traditional application areas such as artificial intelligence and web databases require advanced modeling power than the existing relational data model. In those application areas, object-oriented database (OODB) is better data model since an OODB can providemodeling power as grouping similar objects into class, and organizing all classes into a hierarchy where a subclass inherits all definitions from its superclasses. The purpose of this paper is to develop an OODB concurrency control scheme dealing with multiple inheritance. The proposed scheme, called Multiple Inheritance Implicit Locking (MIIL), is based on so-called implicit locking. In the proposed scheme, we eliminate redundant locks that are necessary in the existing implicit locking scheme. Intention locks are required as the existing implicit locking scheme. In this paper, it is shown that MIIL has less locking overhead than implicit locking does. We use only OODB inheritance hierarchies, single inheritance and multiple inheritance so that no additional overhead is necessary for reducing locking overhead.

The purpose of this study is to build the tax ontology which can be used to manage imposables by the state or local governments. In this, the tax and related concepts were analyzed and then concept hierarchy i.e., taxonomies were formed. Especially, in the concept hierarchy, after multiple inherits were decomposed as 'primitive concepts' and then Rector's 'methodology of ontology implementation normalization', in which defined concepts were recombined, was used. The methodology employed was that the tax system, which was entangled with the direct taxes, local taxes, and property taxes that has multiple-inherits, was expressed explicitly and logically. After that, automatic classification was carried out through the inference engine, consistency was verified. Finally, some practical cases of ontology created were enumerated.

객체 지향 설계 방법론은 현재 소프트웨어 개발에 널리 사용되고 있지만 내장형 실시간 시스템에는 적합한 스케줄링 기법이 존재하지 않기 때문에 제한적으로만 적용되어 왔다. 선점 임계 스케줄링(preeption threshold scheduling: PTS)은 비선점성을 최대한 이용하여 다중 태스킹의 부하를 줄이기 위한 제안되었다. PTS는 전통적인 스케줄링 기법을 대신하여 실시간 객체지향 설계에 사용되기에 적합하나. 이를 위해서는 실시간 동기화의 문제가 해결되어야 한다. 본 논문에서는 PTS를 위한 실시간 동기화의 필수적인 기반을 제시한다. 구체적으로 PTS를 위한 기본 우선순위 계승 프로토콜과 우선순위 실링(ceiling) 프로토콜을 제시한다. 제시된 동기화 기법은 유효 우선순위의 개념을 사용하여 우선순위를 계승하도록 하며, 선점 임계 실링 대신 우선순위 실링을 사용한다.

This paper addresses the issue of constraints on the conversion of the participle II in German, proposing a constraint-based lexical semantic approach. I argue against the widely accepted syntactic view which is based on the dichotomous distinction of intransitive verbs, which has been advanced by the Unaccusative Hypothesis [Perlmutter (1978)]. Several arguments are also given against the semantic view which is based on some aspectual notions such as 'telicity', 'transformativity' or 'terminativity'. The crucial constraints on the conversion of the participle II in German, it is argued, is instead two lexical semantic entailments, movement with a definite change of location and affectedness. These and other lexical semantic entailments in the sense of Dowty (1991) are encoded into the multiple inheritance type hierarchy of qfpsoa. The proposal made in this paper is based on the multiple inheritance hierarchy which is envisaged in a recent framework of head-driven Phrase Structure Grammar.

The object of this study is to find ways of the modern succession of folklore by attempting the creation culture contents and looking into the aspects of using 'Jangjamot Legend'. Folk tale which has been handed down among people for many years is that story contents that are enjoyed by anonymous many people. The original narration and the cultural elements of 'Jangjamot Legend' which show the origin of a certain pond and rock can be used for creation of culture contents. The legend has been created the video contents or used the origin of the village ritual and festival in different areas. If the festival and the contest related to the legend is activated, more contents of the original narration will be created by the folklore or tourism. The preservation of the original narration will be easily accessed by the mass about 'Jangjamot Legend'. The cultural elements which are inherent in the legend shall cause the creation of consistent and effective contents. Through these contents creation, folklore will be passed on to the next generation with the obtain of universality in the modern times.

본 논문의 목적은 ‘다중 동사성 명사 구문’(Multiple Verbal Noun Construe-tions)의 논항실현 양상을 이론 중립적으로 고찰해 보고, 이 분석을 제약기반 문법 이론인 최근의 핵 심어주도 구구조문법 (Head-driven Phrase Structure Grammar)틀 안에서, 특히 다중계승위 계를 가정하는 제약기반 어휘부를 기반으로 형식화해 논항의 실현과정을 기술하고 설명하는 것이다. 우선 일본어의 유사한 현상을 분석한 Grimshaw & Mester (1988)의 격실현 양상에 관한 일반화를 기반으로 한국어 동사성명사구문의 논항실현 양상을 ‘논항전이’ (argument transfer)라는 이론적 장치를 이용해 형식화할 수 있음을 보이고, 동사성 합성명사의 논항구조를 만들기 위해 ‘논항합성’(argument composition)이라는 이론적 장치를 제안한다. 나아가서 다중 동사성 명사구문의 논항실현 과정에서 보이는 겹격표지 현상을 ‘격 복사’(case copying)를 제안해 동사성 명사의 격표지가 합성 명사에서 분리되어 문장단위에서 실현될 때 동일한 격을 복사해 실현한다는 점을 주장하고자 한다. 이 주장을 뒷받침하기 위해 수동과 능동 등 문법기능의 변화현상에서 하위범주화된 요소들의 격변화가 자의적이 아님을 실례를 들어 보여 주고자 한다. 일본어의 경동사 (light verbs)에 관한 분석 인 Grimshaw Meste, (1988) 이래 한국어에서도 이와 유사한 구문에 대한 재조명이 활발하게 이루어져 왔다 (Ryu (1993b), 채희락 (1996), Chae (1997) 등 참조). 한국어에서 ‘하다’와 동사성명사(verbal nouns)가 결합하여 이루어진 ‘동사성명사구문’ (Verbal Noun Constructions)에 대한 기존의 논의는 대부분 하나의 동사성 명사가 ‘하다’나 ‘되다등 소위 문법기능을 바꾸는 ‘경동사’들과 결합하여 복합술어가 되는 문법적 현상에 초점이 맞춰져 있었다. 그와 비교해서 동사성 명사의 어근이 두 개 이상 결합하여 동사성명사들끼리 합성명사(compound nouns)를 이루고 그 동사성 합성명사가 문법기능의 변화를 바꾸는 ‘경동사’와 결합하여 이루어진 복합술어에 대해서는 논의가 거의 없는 형편이다. 특히 이 지적은 핵심어주도 구절구조문법틀 내에서는 논란의 여지가 없다. 본 논문의 대상은 바로 이러한 합성 동사성명사의 논항구조와 동사성명사에 의해 하위범주화된 논항들의 문법적 실현양상이다.

This paper suggests a multi-agent message transport architecture based on the message-oriented middleware ZeroMQ. Compared with the other middlewares such as CORBA, Ice, and Thrift, ZeroMQ receives a good score in the evaluation of performance, QoS (Quality of Service), patterns, user friendliness, and resources. The suggested message transfer architecture borrowed many basic concepts like agent platform, AMS (Agent Management System), and MTS (Message Transfer System) from FIPA (Foundation for Intelligent Physical Agents) standard multi-agent specifications, and the architecture inherited the strength of the architecture from the multi-agent framework SMAF (Smart Multi-Agent Framework). The architecture suggested in this paper is a novel peer-to-peer architecture which is not known to the ZeroMQ community. In the suggested architecture, every MTS agent uses only one ZeroMQ router socket to support peer-to-peer communication among MTS agents. The suggested architecture can support closely collaborating software areas such as intelligent robots as well as the traditional application areas of multi-agent architecture. The suggested architecture has interoperability and scalability with the ZeroMQ devices and patterns.

Since the beginning of history, men have done mimesis and produced illusion and succeeded art and culture instinctually. The subject which mention above included the object which can order and space around that. Perspective which began the Renaissance age was dominant way about understanding space in western history and it made modern visual system. Direction way of space which based perspective is changed as horizontal data included multi-layer structure in digital media age. This character make us possible to represent the space more efficiently. So we must have pay attention the direction way of space based on digital media, because it has meaning to show human value beyond a methodology of visual art culture.

In this paper, the 'facility' and its related concepts were analysed, and then ontological conceptual definition for the facility was conducted based on a variety of relationships between those concepts. First, as a facility conception relation, inclusion relation, instance relation, rule relation, attribute relation and part-whole relationships were investigated. Second, facility concepts were prescribed as a physical entity in which many parts were functionally integrated. Third, by strictly separating the basic concept and role concept, reading facility, exhibit facility, etc. were not supposed to make multiple inheritances by putting subordinate concepts as those of role concepts, not those of the concept of facility. Fourth and lastly, an ontology for the facility was made by using OWL DL.
