분단 이후 북한은 우리와는 다른 언어정책을 추진해 왔고, 그 결과로 지금은 남북한 언어 정책에서 많은 차이를 드러내게 되었다. 본 논문은 북한 문화어 형태소 분석 시스템(NKMA)의 구축을 위한 어절 구조를 제시한다. 북한 문화어의 형태소 분절 및 분석을 위해 사용된 어절 구조는 대체로 말토막 단위와 일치하므로, 음성언어의 인식을 위한 분절 방법에 응용될 수도 있으리라 기대한다.

The purpose of this paper was to present the method of progress efficiency of morphosyntaxical analyzer for French information processing in the view of multilingual information processing. This study indicated that he method prohibit the additional useless word type by decomposing word type by decomposing works which were created by morphological amalgamation. Findings also suggested the need of preprocessing in order to decrease the overload of morphosyntaxical analysis algorithm. In addition, general rules were proposed to divide word form and to decompose complex sentence.

교착어(agglutinating language)에서는 다양한 통사정보가 독자적인 형태소에 내재되어 있다. 국어의 경우 형태소의 분석이 통사구조 분석에 선행되어 이루어져야 하는 이유가 바로 국어의 교착어적인 속성에 기인한다. 이 논문의 전반부에서 국어의 교착성을 명확히 보여주는 등위 접속구문을 핵심어 주도 구구조문법(HPSG)에 의하여 분석한다. 후반부에서는 PROLOG로 구현된 국어의 형태소 분석기와 통사구조 분석기(PARSER)를 소개한다.

The purpose of this study is to develop a Korean word analysis system, which can improve performance of IRS, based on various methods of word analysis. In this study we focused on maximizing the speed of Korean word analysis, modulizing each functional system and analyzing Korean morpheme precisely. The system, developed in this study, implemented optimal algorithm to increase the speed of word analysis and to verify speed and performance of each subsystem. In addition, the numeral analysis processing was achieved to reduce a system burden by avoiding recursive analysis of compound nouns, based on numeral pattern recognition.

It is important to decide processing unit in the large vocabulary speech recognition system we propose a Pseudo-Morpheme as the recognition unit to resolve the problems in the recognition systems using the phrase or the general morpheme. We implement a morphological analysis system and tagger for Pseudo-Morpheme. The speech processing system using this pseudo-morpheme can get better result than other systems using the phrase or the general morpheme. So, the quality of the whole spoken language translation system can be improved. The analysis-ratio of our implemented system is similar to the common morphological analysis systems.

This study was carried out to investigate the sheet formation properties of Morus Hanjis, made of bast and whole stalk pulps by different pulping methods, such as alkali, alkali-peroxide and sulfomethylated pulping. Two species of Morus, M. alba and M. lhou, were used. Effect of morphological properties of pulp stocks on the sheet formation and its gray levels based on optical property were evaluated using an Image analyzer. In addition, the effect of fiber distribution index(FDI) which was calculated from tile data of Confocal laser scanning microscopy(CLSM) on the sheet formation and optical properties of Morus Hanji were also discussed. On the sheet formation, Hanji from whole stalk pulp was superior than that of bast pulp. The more the sheet formation improved, the more paper opacity decreased. In the aspect of Hanji's surface characteristics analyzed by an Image analyzer, the average gray level and its standard deviation of Hanji from the whole stalk pulp were rather lower than those of bast pulp because of better sheet formation of the former. However, high brightness Hanji showed high value of gray level. The sheet formation and paper opacity were increased with the decrease of standard deviation of gray level. From these results, gray level measurement could be used to predict the paper opacity as well as sheet formation. Sheet formation of whole stalk Hanji and its FDI measured by CLSM were higher than those of bast fibers. In conclusion, the sheet formation and opacity of Hanji could be evaluated by standard deviation value of Hanji's gray level using an Image analyzer and by fiber distribution index using CLSM.

The relationships between morphological structures and residual stress behaviors of polyimide thin films depending on isomeric diamines were investigated. For this study, Poly(phenylene biphenyltetracarboximide) (BPDA-PDA) and poly(oxydiphenylene biphenyltetracarboximide) (BPDA-ODA) films were prepared from their isomeric diamines: 1,3-phenylene diamine (1,3-PDA) 1,4-phenylene diamine (1.4-PDA), 3,4'-oxydiphenylene diamine (3,4'-ODA), and 4,4'-oxydiphenylene diamine (4,4'-ODA), respectively. For those films, residual stresses were detected in-situ during thermal imidization of the isomeric polyimide as a function of processing temperature over the range of 25~$400^{\circ}C$ using. Thin Film Stress Analyzer (TFSA). In comparison, residual stress of BPDA-1.4PDA having better in-plain orientation and chain order was the lowest value of 7MPa whereas those of BPDA-1,3-PDA, BPDA-3,4'-ODA, and BPDA-4,4'-ODA were in the range of 40-50MPa. Conclusively, the effect of morphological nature (chain rigidity, chain order, orientation) and chain mobility relating to the g1ass transition behavior on the residual stress of isomeric polyimide thin films wart analyzed.

Purpose: This study sought to compare the elemental constitution, morphological characteristics, particle size distribution, biocompatibility, and mineralization potential of Ortho MTA (OMTA) and ProRoot MTA (PMTA). Materials and Methods: OMTA and PMTA were compared using energy-dispersive spectrometry, particle size analysis, and scanning electron microscopy. The biocompatibility and mineralization-related gene expression (osteonectin and osteopontin) of both MTAs were also compared using methylthiazol tetrazolium assay and reverse transcription-polymerization chain reaction analysis, respectively. The results were analyzed by Kruskal-Wallis test with Bonferroni correction. P-value of <0.05 was considered significant. Result: The morphology of OMTA powders was similar to that of PMTA. The constituent elements of both MTAs were calcium, silicon, and aluminum. The mean particle sizes of OMTA and PMTA were 4.60 and 3.34 mm, respectively. Both MTAs had equally favorable in vitro biocompatibility and affected the messenger RNA expression of osteonectin and osteopontin. Conclusion: Within the limitations of this study, OMTA could be a promising biomaterial in clinical endodontics.

In this paper,we present an efficient morphological analysis model for Korean which produces from an input word all the feasible sequences of morphemes in the word.This model is deterministic in applying spelling rules,and has few redundant computations in processing complex and ambiguous words.This is the effect of three types of new techniques:first,a new method for interpreting speilling rules;second,predictive rule applications which restrict to the spelling rules suitable for the input word;third,the use of dynamic programming which enables the analyzer to avoid recomputing analyzed substring in case the input word is morphologically ambiguous.our model has been experimented with 413,975 word randomly selected from the corpus of Korean elementary textbooks.Experimental results show that our model guarantees fast and reliable processing.

한국어 형태소 분석기의 효율성에 영향을 미치는 요인은 분석 알고리즘의 효율성보다도 어휘 사전 등 형태소 분석과 관련된 여러 가지 요인들이 미치는 영향이 훨씬 더 크다. 따라서 단어의 유형 분류 기법이나 불규칙 용언의 분석 방법을 비롯하여 어휘 사전의 구조 및 크기, 알고리즘의 선택과 구현 등 형태소 분석과 관련된 모든 요소들을 형태소 분석에 적합하도록 구성하여야 한다. 본 논문에서는 어휘형태소 사전과 문법형태소 사전의 크기, 한글 문서에 나타나는 단어의 특성 등 형태소 분석기의 효율 및 성능에 영향을 미치는 요소들을 고찰하였다. 그 결과로 알고리즘의 효율보다는 사전 탐색 시간이 형태소 분석에 미치는 영향이 매우 크다는 것을 알 수 있었다. 이와 같이 형태소 분석기의 성능에 영향을 미치는 요인들을 고려하여 구현된 범용 형태소 분석기 HAM에 대하여 형태소 분석 기능과 철자 검사 기능을 실험하였다. 형태소 분석 성공률에 대한 실험 결과 99.46%의 분석률을 보이고 있으며, 맞춤법 검사 기능으로는 상용화된 철자 검사기와 비슷한 성능을 보이고 있다. HAM의 처리 속도는 pentium 120MHz linux 2.0 환경에서 1 초에 약 1,000 단어를 분석한다.
