It has been a concern for the remediation of petroleum contaminated soil by effective measures. To achieve this purpose, first of all, it is necessary to estimate how much the petroleum could be in soil when spilled. Though the adsorption experiment of petroleum-hydrocarbon-vase to the selected soils which contains different amount of soil organic matter, the following results were obtained. The partitioning coefficients for soils were increased exponentially with the increase of soil/solution ratio. The adsorption of petroleum hydrocarbon(TPH) to soil was directlu influenced by soil organic matter content rather than specific surface area, that is, the adsorption of TPH was increased proportionally with the increase of soil organic matter content.

To evaluate the effect of training, the following were recorded every 3 weeks for the elbow flexors and knee extensors of 5 healthy male volunteers: MVC, 1RM, limb circumference, and surface EMG during isometric MVC or isotonic contraction at 10RM load. From the EMG data, IEMG and variables from a regression analysis between MDF and time were obtained. MVC, 1RM, IEMG, and initial MDF increased linearly over the training period. The fatigue index and slope of the regression line increased temporarily until the 6th week and decreased thereafter. From these results, there appeared to be enhanced neural recruitment of fast twitch fibers in the first 6 weeks and continued enhancement in the recruitment and hypertrophy of fast twitch fibers, which led to increased fatigue resistance, over the last 6 weeks. Accordingly, the MDF and IEMG analysis technique could demonstrate the effect of the program detected significant changes in both isometric and isotonic contractions. EMG analysis methods can be used to estimate the electrophysiological and histological changes in skeletal muscles during a strengthening program.

In this thesis, experiment have performed with the speaker recognition divided into text-dependent and text-independent speaker identification using multiplayer feedforward neural network(MFNN) model. Executing results show as follows ; Text-dependent speaker identification Using LPC Cepstral coefficients is somewhat more enhanced than pitch coefficients. Text-independent speaker identification Using almost solely pitch coefficients for each speaker is more enhanced approcimately average 4 ~ 5 % than LPC or LPC Cepstral coefficients. To record speech data of speaker recognition, each 10 speakers which was consisted of five male and female adults Korean pronounce 10 times for three months. And then they are extracted characteristics coefficient through PDA, LPC analysis, and LPC Cepstral analysis to generate input pattern of Multi-layer Feedforward Neural Network.

The aims of this research study is to clear the differences of the learning effects and the cognition of Home Economics by sex in the middle school and to collect the future-oriented educational datas, after implementing the 6th education curriculum. The results of the study are as follows ; 1. Most of students had the cognition that Home Economics is a subject matter of a needful knowledge and skill for the family life, half students a cultural subject matter for the modern life. The former was supported by female students, the latter by male students. 2. Most of students were interested in actual training fields of cooking and hand-sewing, had a strong interest about a field of physical and social-psychological growth. The differences by sex were statistically significant in these fields. 3. Most of students had positive responses in the learning effects of Home Economics. The most useful field was cooking and the worst was the structure and method of sewing machine. 4. The shortage and the dissatisfaction in the learning of Home Economics were lacking of the actual training hours, the old-fashioned teaching methods and the shortage of teaching materials etc.

CSB^(+)-Tree 기반의 DTD 통합 그래프를 이용한 XML 문서 저장 시스템 설계 기법

신성현,송화선,김진호,정영준 강원대학교 정보통신연구소 2004 정보통신논문지 Vol.8 No.-

As information processing recently increases over Internet. there have been many researches about designing an efficient storage system to process a huge amount of information, which is based upon DTD in XML However, most of them have some difficulties in meaningful and structural presentation of XML documents and some restrictions in integration of many heterogeneous documents. In other word, we need a storage system which well-defines the structure of heterogeneous XML documents and integrates them. In this paper, we proposed a technique of an XML documentation storage system using DTD integration graphs based on CSB+-tree. This technique retrieves structural information from elements of XML documents, creates a CSB+-tree based DTD integrated graphs of the man storage system, and generates an integrated storage system by using element mappings. The proposed technique utilizes the man storage system more efficiently in space and provides more faster response time.

최근 전자상거래의 상업성이 부각되면서 많은 기업들과 개인사업자들이 독자적인 웹서버를 구축하고 자사의 상품 또는 기업에 대한 광고 내용을 인터넷을 통해 서비스를 하고 있다. 그러나 소비자들에게 인지도가 낮은 기업이나 전국의 각 지방의 특산품과 토산품 관련 웹사이트들은 소비자에게 홍보가 부족하고, 상품의 종류와 정보의 부족으로 외면을 당하고 있는 것을 많이 본다. 본 논문에서는 이러한 기업들의 카탈로그를 수집하여 재구성한 후, 한 사이트에서 여러 기업의 상품을 검색할 수 있도록 하여 소비자의 접근과, 각 기업의 상거래 사이트를 활성화 할 수 있는 메타 전자 쇼핑몰 개발에 관해 기술한다. 본 시스템의 특징은 로봇이 자동으로 데이터 베이스를 구축하여 소비자가 쉽게 검색 할 수 있도록 주제어 검색과 디렉토리 검색 및 폴더형맵 검색 인터페이스 구성을 가지고 있다는 점이다.

The keratocystic odontogenic tumor(OKC) represents approximately 11% of odontogenic cysts and is decided by microscopic and histopathologic determinant rather than by clinical apprearance. The OKC is noted for its capacity to recur after treatment. In this study, p53, Ki-67, PCNA and cytokeratin 17, cytokeratin 18 expression of OKC in relation to non-recurrenct lesion and recurrent lesion after cyst enucleation were examinated. The p53, Ki-67, PCNA and cytokeratin 17, cytokeratin 18 antibody staining were used. The obtained results were as follows. In proliferating rate of non-recurrent OKCs and recurrent OKCs using p53, Ki-67 and PCNA staing, there was not significant difference. In cytokeratin 17 staining, strong positive reaction was showed in all layers of recurrent OKCs rather than non-recurrent OKCs. In cytokeratin 18 staining, negative or weakly positive reaction was showed in recurrent OKCs rather than non-recurrent OKCs. In summary, it was suggested that the recurrence of OKCs was not related to proliferating rate of epithelium and the prognosis of the recurrence of OKCs is helped using cytokeratin 17 and cytokeratin 18.
