최근 인터넷을 중심으로 한 전자정보 통신의 발달은 종래의 연속간행물 출판과 배포에 새로운 국면을 제공하고 있는데 바로 전자형태의 저널 및 잡지의 출현이다. 특히 디지털도서관의 출현으로 대부분의 학술잡지들을 인쇄본과 함께 전자형태로 출판하는 추세에 있으며, 이러한 추세에 맞추어 각 출판사, 대학, 연구소 및 전운정보센터에서는 학술지를 중심으로 대부분의 자료들을 디지털화하여 온라인으로 제공하고 있다. 본 연구는 주요 도서관들이 이러한 새로운 정보매체, 즉 전자형태의 저널 및 잡지를 수용하는데 있어서 한정된 예산으로 해당 도서관들이 필요로 한 전자저널과 전자잡지를 선별·수집할 때 적용할 수 있는 평가요소를 연구하였다.

One of the most challenging task in closing anterior diastema is avoiding "black triangle" between the teeth. This paper reports a case that the closure of diastema in anterior teeth could be successfully accomplished using direct adhesive restorations and gingival recontouring. The traditional technique using Mylar strip was modified to increase the emergence profile with natural contours at the gingival-tooth interface. Mylar strip was extended out of the sulcus by approximately 1 mm high from the gingival margin, and a small cotton pellet was used to provide the emergence contour. This modified approach is acceptable for the clinical situation.

정상(正常) 및 홀몬처리한 rat난관(卵管) 상피세포(上皮細胞) 특(特)히 섬모세포(纖毛細胞)에서 mitochondrial crystalloid구조를 관찰하여 2가지 형(型)으로 구분하였다. 제(第) 1 형(型)은 mitochondria장축에 대해 경사의 형태로, 제(第) II 형(型)은 평행의 형태로 출현하였다. 이들 구조는 길이 $0.5{\sim}1.2{\mu}m$, 폭 $0.1{\sim}0.2{\mu}m$이며 10nm 간격의 전자밀도가 높은선과 밝은선의 교차를 이루고 있었다. 또한 이들 구조는 정상(正常) 성주기(性週期)에서는 주로 발정기(發情期) 및 발정후기(發情後期)에, 홀몬처리시는 progesterone처리 시보다 estradiol 처리시에 다수출현(多數出現)하는 경향이었다. 이들 구조의 출현의의(出現意義)에 대해서 논(論)하였다.

한 문서에서 동일한 개체(Entity)를 지칭하는 고유명사가 다른 형태로 출현하는 현상은 문서요약의 품질을 떨어지게 만드는 요소이다. 이런 문제를 해결하기 위해서는 각각의 고유명사 및 지칭어를 인식하고 이들간의 상관 관계를 밝혀야 한다. 본 논문에서는 이런 문제를 개체명 조응 대용 관계로 정의하고 출현 특성에 따라 분류한 후 특성에 맡는 처리 방법을 보인다. 이를 위하여 고유명사의 조응 출현 양상에 따른 휴리스틱을 만들고, 고유명사를 지칭하는 명사들의 시소러스를 구축한 후 이들을 처리하는 방법을 제안한다.

This study was conducted in order to provide as a basic materials of sea cliff vegetation structure through distribution related with the landform and growth pattern of mixed growth plants by ordination method in the Peucedanum japonicum community of Korea. The mixed growth plants of frequency over 10% growth with Peucedanum japonicum community of sea cliff was investigated as a total 26 species, and the frequency of appearing plants was the highest in the Aster spathulifolius(55.7%). Growing pattern of mixed growth plants was a difference by the landform factors as such the inland side, coastline side, flat and slope. Growing pattern was classified into typicality type, one-sided type and complex type. Growing pattern of the typicality type was good distribution in total landform factors, the one-sided type was good distribution in 1 landform factor and the complex type was good distribution in 2 landform factors. In growing pattern of mixed growth plants with Peucedanum japonicum, Artemisia capillaris and Sedum oryzifolium was typicality type, Elymus dahuricus and Artemisia princeps was one-sided type, and Aster spathulifolius, Miscanthus sinensis, Calystegia soldanella and Lysimachia mauritiana was complex type. In total plants of mixed growth, growing pattern of 16 species of 61.5% was good as complex type.

The taxonomic revision of the family Mugilidae from Korea was made based on the fish specimens collected from the coasts of the Korea from July 1990 to July 1994. The family Mugilidae was classified into three species belonging to two genera: Mugil cephalus, Liza haematocheilus and Liza carinatus. Previousely Mugil japonicus reported as a species from Korea was confirmed into junior synonym of Mugil cephalus. based on the external and internal morphological characters. A new key to the genera and species of family Mugilidae was proposed and described their distribution in Korea.

It is expected that some Josa/Eomi's are frequently used and others are not in the Korean documents. In this paper. we confirm it through the experiment and show that such information is very useful for Korean language processing. In case of Josa. most frequent 9 Josa's occupied 70% of total Josa's and 20. 32. 69 Josa's occupied 90%. 95%. and 99% respectively. Similarly, most frequent 10 numbers of Eomi's occupied 70% of total Eomi's and 33. 54. 117 Eomi's occupied 90%. 95%. and 99% respectively. We propose a dictionary construction method for Josa/Eomi dictionary that is classified by the frequency information. Furthermore. Josa/Eomi frequency results are very useful for the identification of unregistered morphemes and the disambiguation of lexical ambiguities.

To achieve high compression ratio for Hangul texts, in this paper two text compression algorithms which use the structural feature of Hangul, the frequency of postpositional words, are proposed. The performances of these proposed algorithms are also compared with previous text compression algorithms. The proposed compression algorithms named HLZ77 and HLZW come out from the modification of previous algorithms LZ77 and :ZW, respectively. The major distinction of the proposed ones is that the proposed algorithms use the fixed dictionary of selected postpositional words that appear most frequently in Hangul texts. The performances of HLZ77 and HLZW also are compared with those of LZ77 and LZW, respectively, with respect to the compression ratio. According to the result of performance study, the proposed algorithms are better than the previous algorithms for descriptive Hangul text snce the structural feature of Hangul is helpful to achievement of high compression ratio.
