We suggest how to search news data by dividing structurely, by classifying meaningly, and by itemizing them by contents. The structural division divides the scene using correlative information between frames such as the distribution of the space brightness and the irregularity of brightness, and time relation etc. The meaning classification means to classify the detailed contents of news video as articles comparing special information extracted frame key frame with previous knowledge information. This study classifies the articles as the anchor's scene and the non-anchor's scene using the character that the progress of news is repeated centering around the anchor frames by periods. We get the non-anchor's scene to search the news data itemizing speech scene, interview scene and general scene, and classifying as articles. Also, we use the function of searching for summary by news icons and search the caption by processing the integration of caption, and design them to be able to search the news video quickly classifying news video as contents and indexing them.

Backgrounds and Objectives: Vascular dementia is a group of dementing disoders arising from various stroke syndrome. Among these. subcortical ischemic vascular dementia (SIVD) is regarded as a relatively distinct clinical entity. However, MRI patterns of SIVD are not homogenous. In some patients, lacunes are dominant, and in others, subcortical white matter changes are. This study was designed to compare risk factor profiles between SIVD with and without multiple lacunes. Methods: We divided 47 subjects (22 males, mean age. 68 years) recruited from VADAPET (Multicenter Trial For Evaluation Of The Changes In the PET Images Of Subcortical Vascular Dementia Patient) study into two groups one with more than 5 lacunes in deep gray matter (lacune group) and the other with 5 or less(non-lacune group) Clinical characteristics and laboratory findings of two groups were compared. Results: Nineteen of 47 patients (40%) belonged to the lacune group. The lacune and non-lacune groups d d not differ in the following variables: age, hypertension, diabetes mellitus, hyperlipidemia heart disease, history of stroke or TIA, history of trauma or major surgery, family history of hypertension stroke, or dementia, age at diagnosis of dementia, body mass index, white blood cell count, ESR, CRP, fibrinogen, hemoglobin A1C, total cholesterol. LDL cholesterol creatinine, proteinuria, glucosuria, and microhematuria. However, male sex, smoking alcohol. hemoglobin, and HDL cholesterol were possibly associated more with lacune group SIVD than with non-lacune group (p<0 1) Multivariate analyses revealed that smoking, hemoglobin, and HDL cholesterol were independent predictors of SIVD with multiple lacunes Conclusion: Our study suggests that SIVD with multiple lacunes may be significantly different in smoking habits hemoglobin, and HDL cholesterol from SIVD without multiple lacunes.

In order to obtain the fundamental data for developing an ideal chemistry curriculum in the common science, four kind of common science textbooks were analyzed. Particularly, inquiry activities part was analyzed by the three dimension framework which consists of inquiry content dimension, inquiry process dimension and inquiry context dimension. The average volume of chemistry part in the common science text books was 13% (56 page). In the analysis of the inquiry content dimension of inquiry activities, the total number of themes in four kinds of textbook had similar inquiry activities. For the analysis of inquiry process dimension, 'interpreting data and formulating generalizations' category(39.1%) was most emphasized and the categories of 'observation and measuring'(30.8%), and 'building, testing and revising the theoretical model'(16.5%), 'seeing a problem and seeking ways to solve it'(13.5%) follow in order. As for the analysis of the inquiry context dimension, the scientific context was 82%, the individual context 1.8%, the social context 7.8% and the technical context 7.8%. It showed that the proportion of STS related contents in inquiry activities was 18%. For the purpose of common science text book in the 6th curriculum, it is expected to increase the proportion of the high level inquiry process and the proportion of STS related contents.
산전 태아사망 환자에서의 Mycoplasma hominis와 Viridans streptococcus감염 1예

Mycoplasma hominis was isolated from a Bartholin's gland abscess 70 years ago, and ureaplasmas were isolated from the genital tract about 20 years later. Subsequently, reports incriminating mycoplasmas in the known adverse outcomes of pregnancy have been reported. Without doubt these genital mycoplasmas are able to invoke an inflammatory response and take part in the cascade of events that culminate in preterm birth. Amniotic fluid infection results in considerable pregnancy wastage in the pregnancy. In these cases Gram-positive organisms, especially group B streptococcus and Streptococcus viridans were the most common pathogens isolated. In our case, the patient has fever and vaginal discharge at 14+4 weeks gestation and two days after intrauterine fetal death was seen. The vaginal culture and sensitivity shown Mycoplasma hominis and Vihdans streptococcus. We experienced a case of Mycoplasma hominis and Viridans streptococcus infection in a patient with intrautehne fetal death and report with a brief review of literatures.
고등학교 공통 과학내 화학 영역을 중심으로 한 STS 내용 분석

Science-technology-society(STS) has been concerned with a reform in science education as a new direction and goal for science education. STS was introduced in the Fifth curriculum an was more emphasized in the Sixth curriculum. In this study, The STS materials in the chemistry part of common science textbook were analyzed. In the chemistry part of common science textbooks, average 14% of the total page content was devoted to the STS materials. The STS materials were included 23.8% in the chapter of reactivity of materials, 14.17% in the control factors on reaction kinetics, 10.7% in exothermic reaction and endothermic reaction, 10% in elements with similar reactivity. The STS materials are analyzed by STS topics by Piel(1981). 34.6% of STS materials were the topics on effects of 'socialization of science', 31.8% on 'technological developments', 16% on 'environmental quality and utilization of natural resources', 13% on 'energy', 3.6% on 'human engineering', and there was no topics on 'space research and national defense', and 'population'. The topics of 'socialization of science' and technology developments were covered in all chapters. The topics of 'environmental quality and utilization of natural resources' and 'energy' were covered in 3 chapters. The activities of STS program in the common science textbook were mostly consists of example study, inquiry research, data analysis. However there was no role play and practical work.

The cyclopolymerization of 4-ethyl-4-hydroxy-1,6-heptadiyne was carried out by transition metal catalysts such as MoCl_(5) or WCl_(6)-based catalysts. The catalytic activity of MoCl_(5) for this cyclopolymerization was greater than that of WCl_(6). The polymerization of 4-ethyl-4-hydroxy-1,6-heptadiyne by MoCl_(5) alone gives a quantitative yield of polymer. WCl_(6)-based catalyst system was not effective in this polymerization. The obtained polymer was generally insoluble in common organic solvents. The IR spectrum of poly (EHH) showed the stretching band of the carbon-carbon double bond at 1590-1650 cm^(-1) indicate a high conjugation. The thermal properties and oxidative stability of poly(EHH) were also studied. The electrical conductivity of the I2 doped poly(EHH) was 1.2 - 2.5 × 10^(-4) Scm^(-1). 본 연구에서는 4-위치에 에틸기와 히드록실기를 동시에 갖는 1,6-heptadiyne 유도체를 합성하여 이를 여러가지 전이 금속 촉매를 사용하여 합성하였다. MoCl_(5) - 단독 촉매를 사용할 경우 가장 높은 중합수율을 보였으며 WCl_(6)- 계 촉매의 경우 중합체가 얻어지지 않았다. 합성된 고분자는 여러 가지 분광 법으로 확인한 결과 주 사슬에 6각형 고리 구조를 가지면서 공액이중결합을 구조를 갖는 것으로 확인되었다. 중합된 고분자는 치환기의 효과로 여러 용매에 쉽게 용해되었으며 산화안정성도 높은 것으로 확인되었다. 합성된 고분자를 요오드로 도핑 시켜 전도도를 조사한 결과 1.2 - 2.5×10^(-4) Scm^(-1)를 갖는 것으로 확인되었다.
