조응어 해석(Anaphora Resolution)은 여러 응용 분야에 적절히 적용됨으로써 자연어 이해에서의 양적. 질적 향상을 가져 올 수 있다. 구어에서 조응어(anaphor)는 화자와 청자간에 공유된 정보를 간략하게 나타내는 형태이다. 특히, 구어를 주된 사용 언어로 하는 대화 시스템에서의 조응어의 양상을 살피고 해석하는 문제는 인간과 기계간의 의사소통(man-machine communication)을 온전히 하는 과제이다. 이 논문에서는 인간과 기계간의 대화 시스템(man-machine dialogue system)에서 흔히 쓰일 수 있는 조응 표현에 중점을 두어 그 유형을 살피고 해석의 방식을 제시하도록 한다.

The normal aging process on speech production and these changes are perceived by listeners. This study examined whether age perception changed under various conditions of prosodic manipulations in normal listeners, comparing the prosodic changes according to age and sex in adulthood. The older and younger voices were resynthesized by manipulation of the speaking rate and pitch to shift the perceived age of the groups toward each other. Two-way repeated ANOVA were conducted to determine if the prosodic type of resynthesized cue resulted in a significant shift in perceived age of young and old voices. The manipulation of the speaking rate resulted in a significant shift in perceived age for the older and younger groups. A significant shift in age estimates was not observed for the younger male group when pitch was manipulated. There were significant gender-by-age group interactions for prosodic manipulation type. Age-related changes in the prosodic properties of speech may ultimately influence speech perception.

A study was carried out for production of a pigment : bluish purple, using a mutant Streptomyces californicus KS-89-7. The mutant was induced from Streptomyces californicus KS-89 with N-methyl-N-nitro-N-nitrosoquanidin(MNNG). It was immobilized on an inert substance made of colloidal sillica and 3.5% sodium alginate with 1 to 10 ratio. The diameter of inert bead was 2mm, and number of immobilized mutant spore was approximately $1.0{\times}10^7$/ml. It was packed in a column reactor and fermentation was conducted with a substrate made of soluble starch 1%, glycerol 1.0%, sodium glutamate 0.1%, sodium nitrate 0.05%, L-prolin 0.025% and with some trace elements. The aeration for production of the pigment was 2.5m1/min with semi-continuous fermentation. The pigment production reached at peak on 8 days of fermentation, and the mutant produced the pigment 1.8 times more than its parent strain with the maximum pigment production of $1.72g/\ell$. The pigment production continued for 24 hours of fermentation, and at the end of the fermentation the mutant produced the pigment $1.52g/\ell$.

The typical characteristic shape of the Koryo inlaid celadon Maebyong was reviewed and the symmetry of S curve was analyzed by the method of geometric basis. The contours of Maebyongs sampled were drawn and divided with geometric rectangular proportion. The analytical results showed the static and dynamic symmetric of the vase and the ratios of height and base of the rectangles established for the analysis of their shapes were almost 1:1, 1:${\sqrt{2}}$ and 3:5(known as the Golden Ratio). The excellent beauty of the curve was principally caused by the balanced and harmonius division of the proportional rectangles. The contour line was developed along with the logarithmic spiral modified and introduced lately into the shape of Yi dynasty's liquor bottle.

In order to reduce operating voltage of the GaN based blue-violet laser diodes, the effect of highly Mg doped GaN layer, which was grown below ohmic contact metals, on contact resistivity as well as operating voltage has been investigated. The addition of the highly Mg doped GaN layer greatly reduced contact resistivity of Pd/Pt/Au ohmic contacts from $5.2 \times {10}^-2 \Omegaㆍ$\textrm{cm}^2$ to 7.5 \times {10}^-4 \Omegaㆍ$\textrm{cm}^2$$. In addition, it also decreased device voltage at 20 mA by more than 3 V. Temperature- dependent sheet resistivity of the highly Mg doped GaN layer suggested that the reduction of the contact resistivity could be attributed to predominant current flow at the interface between the Pd/Pt/Au contacts and p-GaN through a deep level defect band, rather than the valence band.

정보화시대에 접어듦에 따라 많은 공공기관에서 고령층을 위한 정보화교육을 실시하고 있다. 대부분의 공공기관에서 정보화교육을 신청하기 위해 회원가입 또는 본인인증을 요구하고 있고 회원가입을 위해서는 본인인증이 본인인증을 위해서는 본인명의의 휴대폰 또는 아이핀이 필요하다. 하지만 휴대폰을 이용한 본인인증의 경우 본인명의의 휴대폰이 없을 경우 본인인증을 받을 수 없고 아이핀 발급의 경우 고령층 사용자가 발급하기에는 복잡한 것이 사실이다. 따라서 본 논문에서는 비회원 신청을 기반으로 신규 신청자와 재신청자를 구분하여 본인인증정보를 관리하는 시스템을 설계 및 구현하였다. 신규 신청자의 경우 휴대폰인증, 아이핀인증, 방문인증 중 인증방법을 선택할 수 있으며 추첨 시 선정자의 성명, 생년월일, 성별을 조합하여 인증코드를 생성하여 저장 후 재신청시 해당 인증코드를 확인하여 본인인증 없이 교육신청이 가능하도록 구현하였다.

The optimal cultural conditions for production of the bluish purple prgment by the cultivation of Streptomyces californicus KS-89 were determined with various substrates. The carbon and nitrogen sources on the production of pigment indicated that soluble strarch and glycerol as carbon sources and sodium glutamate sodium nitrate as nitrogen sources given a mzimum yield of the pigment at 3$0^{\circ}C$ for 7 days. The addition of ferrous sulfate was essential. The highest production of pigment was observed with cultivation in a medium containing 2.0% soluble starch 1% glycerol 0.5% sodium glutamate 0.05% sodim nitrate 0.001% L-proline 0.025% K2HPO4 0.005% MgSO4 .7H2O, 0.04% FeSO4.7H2O, 0.001% thiamine.HCl and pH7.0.

Aqueous solution pigment produced by Steptomyces californicus KS-89 showed a vivid bluish purple pigment and purified by silica gel column chromatography. The pigment indicated a deep purple color zone by the C. I. E chromatic diagram and showed UV absorption maxima at 575nm. The color intensity in aqueous solution was fairly stable in the ranges of pH5-8 and was not affected by UV light however sometimes it had faded slightly by the heat. It was possible to prevent significantly by the addition of metal salt. Especially this pigment has no mutagenicity and antitumor activity and it appears to be devoid of antibiotic activity.

This study aimed to identify the differences in pitch perception between tonal and non-tonal language listeners. A total of 60 Korean and Chinese listeners participated in the perception test. A two-syllable nonsense word /paba/ was manipulated in five steps. The pitch height or contour on the second syllable was raised or lowered. Both groups were asked to select which of the two syllables had the higher pitch. The findings showed that the majority of Korean listeners (GK) perceived decreased pitch as each peak of the syllable was lowered and perceived increased pitch as it was raised, which means the pitch height is a primary perceptual cue for GK. However, Chinese listeners (GC) perceived sensitive pitch movements as the pitch contour changed. GC's perception may presumably be affected by the L1's tone sandhi. We found it reasonable to assume that language experience has a significant effect on the cross-linguistic perceptual differences between tone and non-tonal language listeners.

음악 감정 분류에 관한 기존의 연구들은 템포, 박자, 음정, 음표, 리듬 등과 같은 음악의 멜로디와 관련된 자질을 이용하여 음악 감정을 분류하였다. 그러나 노래(Song)와 같이 가사를 포함한 음악은 같은 스타일의 멜로디라도 가사의 내용에 따라 음악에 대하여 청자가 느끼는 감정이 크게 다르다. 본 논문에서는 감정 온톨로지를 활용하여 노래 가사를 감정에 따라 분류하는 방법에 대하여 제안한다. 기구축 된 감정 온톨로지를 바탕으로 네 가지 통사적 규칙을 적용하여 노래 가사로부터 감정 자질을 추출한다. 추출된 감정 자질을 이용하여 Naive Bayes, HMM, SVM과 같은 기계학습 기법을 이용하여 8개 감정 그룹에 대해 58.8%의 정확도를 보였다.
