This study was to suggest improvement for physical in life of Taejon after analyzing current sports facilities. This research, which was carried mainly through related documents, studied present condition of public of private sports facilities and suggested the following to be improved: 1. The number of sports facilities in Taejon to activate physical education in life is the lowest among the largest 6 cities. And they should be enlarged in relation to existing facilities, local characteristic, and local equality with other cities. 2. Various sports facilities should be added to make participants' sports effect the largest one and to raise the rationality of sports. And the criterion of sports facilities both in school and in company should be strengthened to be used for physical education in life. 3. Most public facilities are mainly used for sports games and this result in low degree of constitution to physical in life. So a solution should be made to use these facilities. Furthermore, the security, cleanness and convenience of facilities should be improved to enlarge the participants' desire.

Experimental measurement of electrical conductivity and Hall coefficient have been made as a function of temperature on n-type five ?? alloys which had as component ratio of 0.02, 0.11, 0.21, 0.275, 0.32 respectively. Theorical calculation of electrical conductivity and Hall coefficient have been made on a three band model using the method of Fletcher and Butcher and the resulting values fitted to the experimental measured data. Where unknown parameters were energy of L₁and X₁band edge, and the compensated acceptor density. The resulting analysis show the band gap variation given by ?? and ?? at room temperature. Various scattering mechanisms are also discussed in this work.

Important main odorous compounds and VOCs(volatile organic compounds) possibly emitted from the Jeon-Ju Industrial Sites were identified and measured in amount through making air sampling over Jeon-Ju Industrial Sites and analyzing them with the sate of the art analytical instrument. Sampling sites were chosen 8 points by considering the industrial characteristics for the 1,2 Industrial Sites and 2 points for the 3 Industrial. Site Sampling times were two times, the first one was March. 2002 - April. 2002, and the second was May. 2002 - July. 2002. Canister sampling units and polyester bags were used to collect 6 liters air samples during 1hour or 3minutes for VOCs and polyester bags were used to sample 10 - 50 liters of air for 3 minutes depending on analytic characteristics of odor compounds. The important main VOCs were measured as acetone, ethyl benzene, n-hexane, m,p-xylene, toluene, M.E.K.(methyl ethyl ketone), isopropanol, ethyl acetate, o-xylene, n-butyl acetate, ethanol, benzene as in order of average concentration for the Industrial Sites. The main odorous compounds were COS, H2S, CS2, MM(methyl mercaptan), form aldehyde, acetaldehyde for the 1,2 Industrial Sites and COS, H2S, form aldehyde, acetaldehyde were measured as main species for the 3 Industrial Site. NH3 was measured as below the detection limit of the instrument. The concentrations of sulfide compounds for the 1,2 Industrial Sites were relatively higher than ones for the 3 Industrial Site. Among aldehydes, form aldehyde, acetaldehyde were detected very highly as 0.1- 1ppm over all the Industrial Sites.

Background : In recent years, gonorrhea has been panedemic and remains one of the most commom STDs in the world, especially in developing countries. Objective & Methods: For the detection of a more effective therapeutic regimen and assessing the prevalence of PPNG, we have been trying to study the patients who have visited the VD Clinic of Choong-Ku Public Health Center in Seoul since 1980 by means of the chromogenic cephalosporin method. Results: In 1996, 139 strains of N. gonorrhoeae were isolated, among which 53(39.0%) were PPNG. Conclusion: Our results suggests that after a peak of 74.3% in 1993, the prevalence of PPNG in Seoul is gradually declining.

출생 후 성장 발육에 따른 흰쥐 유곽유두의 신경분포 및 변화를 관찰하기 위하여 생후 1,5,10,15,20,25,35일 및 완전히 성장한 흰쥐를 개상으로 calcitonin gene-related peptide(CGRP)를 이용한 면역조직화학적 방법으로 관찰하여 다음과 같은 결과를 얻었다. CGRP-면역양성 신경섬유들이 혀의 양측에서부터 유두 내로 진입하여 성장발육에 따라 그 분포밀도가 중가하다가 10일군부터는 상피의 직하방에 특히 풍부하게 분포하여 subepithelial plexus를 형성하고 있었다. 1일군에서는 CGRP-면역양성 신경섬유의 특징적인 양상인 염주알 모양이 명확히 관찰되었으나 그 이후로는 염주알 모양은 다소 감소하였고 하나의 선으로 보이는 경우도 있었다. 상피 내로 진입하는 CGRP-면역양성 신경섬유들은 5일군에서 드물게 관찰되었으며 taste pore를 가진 성숙한 미뢰가 처음으로 관찰되는 10일군에서 그 수가 증가하여 출생 후 15일군에서는 상피 전반에 걸쳐 풍부하게 관찰되었다. 그러나 그 이후 20일군부터는 미뢰가 존재하는 trench wall의 하방 2/3부위의 CGRP-면역양성 신경섬유는 감소하고 유두의 top surface와 trench wall의 상방 1/3에 CGRP-면역양성 신경섬유가 제한적으로 관찰되었다. The purpose of this study was to investigate the distribution of nerves in the rat circumvallate papilla by each developing stage. The distribution of nerves in the rat circumvallate papilla were investigated by means of immunohistochemistry for detection of calcitonin gene-realted peptide(CGRP). The results were as follows: CGRP-immunoreactive(IR) nerve fibers entered the base of the papilla laterally to form a subepithelial plexus. On the 1st postnatal day, the bead-like appearance, typical appearance of CGRP-IR nerve fiber, was seen, but from the 5th postnatal day the bead-like appearance was seen less clearly and nerve fibers looking like a line were often observed. Mature taste buds having taste pores were first seen at the 10th postnatal day and then, increased markedly after this stage. CGRP-IR nerve fibers entering the epithelium were rarely seen on the 5th postnatal day but they increased in number on the 10th postnatal day when mature taste buds having taste pores were firstly observed and then on the 15th postnatal day, they were observed abundantly throughout entire epithelium. But from the 20th postnatal day, the nerve fibers in the lower two-third of the trench wall in which taste buds exist decreased but on the top surface and upper one-third of the trench wall the nerve fibers were obsered limitedly.

Most of previous signature recognition method mainly used 8 direction chain code, starting point and separated point to recognize signs. In this paper, we propose a signature recognition system using histogram peak mathing. First, for efficient recognition, the proposed system binarizes and normalizes obtained sign images, and then only sign area is extracted. Next, as input data of ART2, the histogram peaks of x and y axis are used. In the experiment using 40 sign images, the proposed system shows about 88% recognition rate.

Recently, as spreading of computer supplement and development of communication technology using network, the web users have rapidly increased in number on Internet environment. Then, new technology development to efficiently classify and retrieve this increasing information is necessarily required. In this paper, we propose a method of information classification with text-mining technique based on the document indexing method using representative keywords for efficient information retrieval. In the experimental results using total 1,200 Korean language articles of 4 categories, the proposed method shows average about 95% performance except information communication category in the classification rate.

Polaron Hopping in the K_(2)O · B_(2)O_(3) · V_(2)O_(5) Glasses

K_(2)O · B_(2)O_(3) · V_(2)O_(5) 계 유리의 조성비에 따른 밀도, 굴절율, 전이온도, 천이금속이온비율 등과 직류 전기 성질을 100~450K 온도영역에서 연구하였다. 실험결과를 비정질 반도체에 관한 전기전도에 대한 이론 모델을 이용하여 분석하였다. 고온 영역에서는 직류전도도의 온도 의존성을 Mott의 포논-도움껑충뛰기 전도모델로 분석할 수 있었다. 활성화에너지는 0.28~0.33 eV로 시료내 V_(2)O_(5) 의 양이 증가할수록 감소하는 경향을 보인다. 저온 영역에서 직류 전기전도도는 Mott의 가변거리 껑충뛰기(variable-range hopping)전기전도도와 잘 일치하며, N(E_(F))값은 국지화 상태에서와 같다. The dc conductivity of K_(2)O-B_(2)O_(3)-V_(2)O_(5) glasses has been investigated in the temperature range 100~450K and physical parameters such as density, refractive indices, glass transition temperature and fraction of reduced transition-metal ion, were observed for various compositions. The experimental results are analyzed with reference to theoretical models proposed for electrical conduction in amorphous semiconductors. The analysis shows that at high temperature region the temperature dependence of the dc conductivity is consistent with Mott's model of phonon-assisted hopping of small polarons. The values of activation energy are 0.28~0.33 eV and decrease with increasing V_(2)O_(5) content in the sample. The lowtemperature dc conductivity data can be well fitted to Mott's variable-range hopping conductivity and the values of N(E_(F)) are also reasonable for localized states.
