  • 본실험은 3년간 동일한 조건하에서 생육한 해장죽(1)과 해장죽(2)의 비교해부학적 연구를 기반으로 하여 서로 상이한 종임을 재확인하였다. 조직학적 연구에 의하여 대과의 진화과정을 다소 구명할 수 있었다. 주맥유관속의 크기, 통기조직, 순관의 크기, 후탄유조직의 비후, 제형세포에 있어서 두종의 뚜렸한 차이를 발견하였다. 외부형태에 있어서도 해장죽(1)과 해장죽(2)는 상위하였으며 해장죽(1)은 절간이 길고 해장죽(2)보다 협과이며 동일한 토양조건에 있어서도 생장율의 차가 생겼다. 두종간의 Paper chrmatography에 의한 정성분기에서도 상이하였다. 이상 제약인에 의해서 해장죽(1)과 해장죽(2) 상위한 종으로써 해장죽(2)는 해장죽(1)의 변종임을 결론지을 수 있었다.

  • Novels include various character names, depending on the genre and the spatio-temporal background of the novels and the nationality of characters. Besides, characters and their names in a novel are created by the author's pen and imagination. As a result, any proper noun dictionary cannot include all kinds of character names. In addition, the novels translated into Korean have character names consisting of two or more nouns (such as "Harry Potter"). In this paper, we propose a method to extract noun phrases for character names and to cluster the noun phrases into coreferents for the same character name. In the extraction of noun phrases, we utilize KKMA morpheme analyzer and CPFoAN character identification tool. In clustering the noun phrases into coreferents, we construct a directed graph with the character names extracted by CPFoAN and the extracted noun phrases, and then we create name sets for characters by traversing connected subgraphs in the directed graph. With four novels translated into Korean, we conduct a survey to evaluate the proposed method. The results show that the proposed method will be useful for speaker identification as well as for constructing the social network of characters.

  • 실시간 교통상황을 정화하게 관측할 수 있는 신뢰성 있는 검지시스템의 개발은 첨단교통체계의 성공적인 현장 구현을 위해 근간이 되는 연구 분양이다. 본 연구에서는 보다 효과적인 검지체계 구축을 위한 노력의 일환으로 이종(異種)의 센서로 구성된 도로구간의 상류부 및 하류뷰 검지 스테이션(detection station)에서 차량의 고유한 특성을 추출하여 개별차량을 재인식하는 방법론을 개발하였다. 상류부에서는 기존의 사각 루프 센서 (square loop sensor)를 하류부에서는 차축의 정보를 얻을 수 있도록 새로이 개발된 비매설식 블레이드 센서(blade sensor)를 이용하여 자료를 수집하였다. 또한, 알고리즘의 평가 결과를 통해 제안된 방법론의 타당성을 검증하였다. 본 연구에서 개발된 차량재인식기법을 활용하여 구간통행시간을 산출하는 방법론은 실시간 교통 모니터링 및 정보제공을 지원하는 유용한 수단이 될 것으로 기대된다.

  • Salmonella typhimurium is a causative agent of the common worldwide disease, salmonellosis. To identify putative invasion genes involved in Samonella infections, a S. typhimurium cosmid library was constructed in noninvasive E. coli DJl. The invasion efficiencies of the cosmid library for cultured HEp-2 and HeLa cells were estimated by tissue-culture invasion assay. 2 out of 1,000 transductants, DHl(pSI623) and DHl(pSI511) were able to invade the cells. Compared to E. coli by DHl(pSI511) increased 25- and 33 fold, respectively. The invasion efficiencies of HeLa cells by DHl(pSI623) increased 31- and 35 fold, respectively. This illustrates that the cosmid clones, DHl(pSI623) and DHl(pSI511) could harbor the invasion determinants derived from genomic DNA of S. typhimurium 82/6915, conferring the invasive characters for the cells.

  • A human bite-mark shows special feature according to the suspect's dentition. The teeth which most frequently give useful bite-marks are six upper and lower anteriors, while the premolar teeth somtimes give marks it is often difficult to distinguish. The author tried to classify and to analize the anterior dentition which makes the bite-mark directly by means of 672 maxillary and 691 mandibular stone model taken from Korean adult aging from 17 to 40 years old. The results were as follows : 1. There was no particular correlation between the presence of six normal-shaped and correctly positioned upper and lower anteriors and the presence of rotation of teeth. 2. Inter central incisor, inter lateral incisor, inter canine width and angles of adjecent teeth were not identical eath other in studied models. 3. The results of this analysis supported the statement that any bite-mark had no same feature.

  • Identification and serotyping for 21 strains of V. parahaemolyticus isolated from diarrheal patients in Japan and Indonesia in 1977 were carried out. The results were as follows: 1. The 21 strains were divided into 5 serovars including O1:K56, O4:K4, O4:K8, O4:K12 and O5:K15. 2. Author's experiences on the isolates in Korea also show that there is no particular difference in the distribution pattern of serovars of V. parahaemolyticus among Korea, Japan and Indonesia. In these respects, there was no geographical difference in these countries.

  • The author modified the Aquard 100 head holder device from Denar Co. to be adequate to the Koreans and to enhance the standardization and reproducibility of the temporomandibular joint radiographs. The results were obtained as follows; 1. The projected central ray was at an angle of 25 degrees. 2. Standardization of patients head position was obtained by means of vertical and horizontal bar which were attached to the head holder. 3. Arbitrary 3 points (A.B.C.) which were on the TMJ area of dry skull were measured for the identification of reproducibility. 4. Measured distances in dry skull were as follow; A-B, 28.0±0.25, B-C 11.9±0.25 and C-A 30.4±0.21, in closed position.

  • Author investigated fluorence antibody reaction for the antigenic relationships between Asp niger group, Asp flavus and Asp parasiticus which was indicated as follows: 1. It was concluded that there are complete differences in the antigenic properties each other because it has not cross reaction, therefore identification of strains will be simpley classified. 2. A complete cross reaction between Asp flavus and Asp parasitic us in the Asp flavus groups existed, accordingly this reaction could not identified the strain and classified between Asp. flavus and Asp. parasiticus. 3. This experiment also followed with the separated each strains from the origin (Meju, Nuruk, ATCC, NRRL), but there no differences. From the above results, this method could be classified between Asp flavus group and Asp niger group in the genus Aspergillus, but classification of Asp. flavus and Asp. parasiticus should hardely conclude with this method.

  • For accurate construction contract time estimation, few parameters are more significant than crew production rates and factors affecting the rates. However, statistical analysis techniques for finding such factors are not always simple mainly because there are many factors and the interaction between factors is not well quantitatively understood. This paper presents methodology of identifying factors driving crew production rates. The methodology is further demonstrated with representative data collected by the author from 13 on-going highway constructions. Three factors were identified as statistically significant drivers of Cap crew production rate: 'Cap Size (m3/ea)'; 'Cap Length (m)'; and 'Cap Shape (Rectangle vs. Inverted 'T')'. It was also found that the production rates are best explained by a multiple regression model with two of the drivers; 'Cap Size' and 'Cap Shape'.
