To learn correctly how irregular verbs conjugate is one of the most important items which must be acquired by learners of Korean. Although a great deal of study has been made on irregular verbs, lots of problems seem to be remaining unsolved or even undescribed. The purpose of this paper is: (1) to give a definition of irregular conjugation of Korean from pedagogical point of view; (2) to describe an appearance of irregular verbs in the spoken and written context; (3) to show appropriate explanation how irregular verbs conjugate.

Effects of incident beam position and intensity on self-pumped optical phase conjugation are presented using barium titanate as an optical phase conjugator. Depending on the position of incident beam, the crystal used consists of four major operating regions: irregular pulsing, regular pulsing, stable phase conjugation, and unstable oscillating regions. In the second region, the pulsing frequency and amplitude of phase conjugate beam are proportional to I$_{in}$ and I$_{in}^{0.85}$, respectively, where I$_{in}$ is the incident beam intensity. In the fouth region, the rising time and intensity of the first-generated pulse are proportional to I$_{in}^{0.92}$ and I$_{in}^{0.81}$, respectively. A frequency shift by beam fanning is also discussed by observing interference pattern from an interferometer.

This paper explores to identify the stem-final consonants of p- and t-irregular verbs in Korean within the framework of Government Phonology. Since the advent of Generative Phonology, the phenomenon of irregular verbal conjugation has been of great interest to Korean phonologists both in linear and non-linear approaches. When we examine these analyses, we find that one of the major issues concerns the identities of the stem-final consonants of p- and t-irregular verbs. The proposals concerning this issue vary considerably from one another. In this paper, I put forward a different view from those proposals in that the stem-fmal consonants of p- and tirregular verbs are tensed p' and t' respectively.

Spatial and temporal dynamics arising in a photorefractive crystal(BaTiO3) during the process of double phase conjugation was studied experimentally. We studied the dynamical effects caused by the buildup of the diffraction grating and turn on of phase conjugated beams, as well as the spatial effects caused by the finite transverse coupling of beams and the propagation direction of beams. We observed conical emission in DPCM. We believe that various temporal and spatial instabilities are due to movement of the nonlinear grating. For a real beam coupling and constructive interaction of interference fringes in the crystal, we observed steady, periodic, irregular temporal behavior. And, by the calculation of the correlation index, we found that the spatial correlation decreased as the transverse interaction region was increased.

This paper proposes a method for analyzing the Korean inflected word in machine translation system. We define the processing rules which are useful of analyzing an irregular conjugation, pesent an parsing algorithm of noun and specifed verb and reduce the space of dictionary by the algorithm.

This research was investigate to understand how moderate bilingual subjects represent the lexicon in second language. Although most researches have focused only on high proficient bilinguals, we analysed how moderate bilinguals who have learned English mostly in school represent the prototype of verb and its inflected form of verb. Results of lexical decision task showed that moderate bilingual subjects used different mental representation depending on whether the verb have regular or irregular conjugation. With regular verbs, the identification of an inflected form was affected by both the frequency of its prototype and that of inflected form, but with irregular verbs, it is affected only by the frequency of inflected form.

전체 광 중계 구간 모두 불규칙한 분산 계수를 갖는 단일 모드 광섬유와 분산 보상 광섬유 (DCF; dispersion compensating fiber)를 이용한 융통적인 분산 제어 링크 구조를 제안하였다. 링크의 융통적 구성은 각 전송 반 구획에서 DCF의 분산 계수를 기준으로 이들을 인위적으로 분포시켜서 가능하게 하였다. 광 위상 공액기 전의 전송 반 구획에서는 DCF의 분산 계수를 점진적으로 증가시키고, 광 위상 공액기 다음의 전송 반 구획에서는 DCF의 분산 계수를 점진적으로 감소시키는 'AD' 분포에서 왜곡된 파장 분할 다중(WDM; wavelength division multiplexed) 신호가 최상으로 보상되는 것을 확인하였다. 따라서 왜곡된 WDM 채널의 보상 효과를 더욱 증가시키기 위해서는 광섬유의 길이, 중계 구간 당 잉여 분산뿐만 아니라 광섬유의 분산 계수에 상관없이 'AD' 분포를 선택할 필요가 있다는 것을 확인하였다.
