In this study, synthetic fiber fabrics such as polyester, nylon 6, acrylic and acetate were dyed with indigoid vat dye. The effects of the composition of alkaline reduction, dyeing time and dyeing temperature on color strength and color fastness of the fabrics were investigated. Also the color fastnesses to wash and light of the dyed fabrics were studied. In dyeing of polyester, nylon, acrylic and acetate fiber fabrics with indigo vat dyes, it appears that these fabrics have high values of K/S up to Ig/L of sodium hydroxide and 6g/L of reducing agent. Indigo vat dyeing for synthetic fiber fabrics was verb fast, and lead to dyeing equilibrium within twenty minutes. The K/S values of dyed fabrics did not changed in dye concentration more than 10% o.w.f.. Synthetic fiber fabrics dyed with indigoid dyes had bad light fastness.

The purpose of this paper is to analyze the lexical-semantic structure of morphologically derived passive verbs in Korean based on Pustejovsky (1995)'s Generative Lexicon Theory (GL) and to explain the change of the root verb's lexical-semantic structure by means of passivization. Passivization in this paper is defined as the unaccusaztivization. In Argument Structure of derived passive verbs, the agent argument is deleted and the theme argument is realized as a syntactic subject. As for Event Structure, derived passives express left-headed event (achievement), whereas their roots denote right-headed event (accomplishment). In Qualia Structure, passive verbs and root ones have the same Fomal Role, but in Agentive Role of passive verbs, an act weakens to a process. Both Formal and Agentive Roles have the same theme argument.

ECM across a CP in Korean poses difficulties from the standpoint of the locality of A-movement/agreement. A phase-based analysis is developed which requires two steps: (i) in the embedded CP, VP/VP containing its VP-internal subject first moves to Spec-CP, which renders the subject accessible to the matrix v, in accordance with Chomsky's Phase Impenetrability Condition; (ii) ECM takes place in a local relation between the matrix v and the embedded subject. It is shown that the otherwise puzzling fact that ECM across a CP, but not Passivization across a CP, is affected by the type of the embedded verb in Korean is accounted for in a principled way, based on the assumption that CP and CP, but not TP and VP, are phases.

One main complexity of the copula constructions concerns a mismatch between morphology and syntactic constituency: the copula seems to form a morphological unit with the immediately preceding element, whereas in terms of syntax the copula appears to take this as its syntactic complement. In capturing such mismatches, we show that the copula is treated as an independent verb at the level of tectogrammatical structure (or syntax tree), whereas as a bound morpheme at the level of phonogram-matical structure (or domain tree), in terms of Dowty 1992 (or Reape 1994). This paper, adopting the notion of DOMAIN in HPSG, shows that copula constructions are a subtype of compacting-constructions. These constructions compact the domain value of the copula and that of its preceding element together into one domain unit, eventually making it inert to syntactic phenomena such as scrambling, deletion and pro-form substitution. This construction-based approach provides a clean analysis for the formation of the copula construction and related phenomena.

This paper, conducted within the GB framework, investigates inversion phenomena in the functional categories, Focalization Phrases and Topicalization Phrases. The leading idea of this paper is that formal feature checking in these two functional categories is mostly responsible for inversion in which either verb or auxiliary verbs appear in front of subjects and also it will try to find an answer to the following questions: "What are the features that trigger the inversion?" and "Can all the inversion constructions explained by Haegeman's Focalization & Topicalization?" My discussion is largely based on English inversion constructions such as wh-inversion, negative inversion, and adverbial inversion. Also I will show there are some problems in Topicalization and Focalization analysis to explain some inversion constructions and present Rizzi(1999)'s analysis for those problems.

When an ending which begins with 'a/a'combines to a stem,'a/a'can be deleted.Especially when ot combines to an h-irregular verb,it is represented as a variant like '-a-','-e-','-ia-',or'-ie-'.In order to analyze the variants of 'a/a',we suggest the format of a grammatical morpheme dictionary which is represented as a binary tree and several procedures which process the variants so that the unexpected errors can be removed which occur frequently when we analyze Korean worl phrase.

Argument alternation in English sentences such as "load hay onto the truck" vs. "load the truck with are swarming in the garden" vs. "The garden swarms with bees" present an interesting dilemma for ling in several ways. Along with each kind of syntactic rearrangement of arguments goes a subtle but sig systematic change in the verb's meaning. This has been called as different terminology such as "D "Verbal diathesis", and most commonly as "Argument alternation". Dowty adopts tern Agent-subject(A-subject) form and Location-subject(L-subject) form in referring the two kinds of analyses as well as describes their different properties. In this paper. I basically follow assumption while surveying several 1inguists's analysis and show its theoretical adequacy.

본 논문에서는 문장에서 동사를 파악하여 명사간의 의미를 부여하는 자동학습 온톨로지 기반 정보 검색 시스템을 제안한다. 정보의 양이 무한히 증가하고 있으며 웹의 발전에 따라 적합한 정보를 찾아내야 하는 효율적인 정보 검색 시스템의 필요성이 증대되고 있다. 단순히 키워드의 가중치에 따른 검색의 순위화는 사용자의 의미를 이해하지 못한 검색 결과로서 사용자로 하여금 결과를 다시 한번 직접 검색해야 하는 불편함을 제공하고 있다. 이러한 문제점을 해결하기 위해서 문장에서 동사를 파악하여 명사 간의 의미를 부여하고 문서 내에서 단어 간의 의미를 파악하여 검색의 질을 개선하는 방법을 논의한다. 또한, 문서에서 단어의 관계를 스스로 학습 가능하여 구축되는 자동학습 온톨로지 기반의 정보 검색 시스템을 제안한다.

한국어에서 보조사로 인해 발생하는 격 모호성(case ambiguity) 문제를 해결하는 알고리즘을 개발하였다. 이 알고리즘은 용언의 하위범주화 사전, 용언과 그 용언의 보어가 되는 체언간의 선택 제약, 체언의 의미 정보를 제공하는 시소러스 등의 구문.의미 지식과 더불어 몇 가지의 휴리스틱 규칙을 이용하며, 필수 보어의 생략이 흔한 한국어의 특성에 잘 대응한다. 중규모의 하위범주화 사전 및 시소러스를 이용한 실험에서 만족할 만한 성능을 보였다.Abstract An algorithm is proposed for the resolution of case ambiguity caused by the use of auxiliary postpositions in Korean language. The algorithm utilizes verb dictionary which provides subcategorization information and selectional restrictions, and the thesaurus as well as a set of simple heuristic rules. The algorithm is appropriate for Korean language where required complements are often omitted. The algorithm performed successfully in an experiment using medium-sized subcategorization dictionary and thesaurus.
