Background: The purpose of this study was to document the incidence and clinical characteristics of patients with tuberculosis (TB) in combat and auxiliary police, living in a group, in Korea where the incidence rate of active TB in a general population is higher than in Western countries. Materials and Methods:We retrospectively reviewed the medical records of all tuberculosis patients diagnosed at National Police Hospital from January 2002 through December 2004. Results:In 2002-2004, a total of 156 cases of tuberculosis were identified with the mean (Standard deviation) age of 20.6 (±1.0) years. Of these, 134 (85.9%) patients were registered as new cases, 11 (7.1%) as relapse, 2 (1.3%) as failure, 5 (3.1%) as treatment-after-default cases whereas 4 (2.6 %) patients were not included in any categories. Average annual new TB rate and smear-positive TB rate were 86.5/10^(5) and 17.4/10^(5) person-years, respectively. In 12 of 31 smear-positive cases, time from onset of symptoms to diagnosis was more than 30 days. Two multidrug-resistance TB cases were identified and two suspected outbreak episodes of TB had occurred during 3 years. Conclusion:There was no statistically significant difference in the incidence rate of new cases of TB between the general population aged 20 to 29 years and combat and auxiliary police in Korea. 배경 : 국내 결핵의 발생은 감소 추세에 있으나 여전히 후진국형 발생양상을 보이고 있다. 특히 집단생활을 하는 젊은이들에서 발생하는 결핵의 유행이 간헐적으로 알려지고 있어 우려를 낳고 있다. 이에 저자들은 최근 전경대원의 결핵 발병 양상에 대해 알아보고자 본 연구를 시행하였다. 재료 및 방법 : 2002년 1월부터 2004년 12월까지 3년간 경찰병원에서 결핵 진료를 받은 전경대원의 의무기록을 후향적으로 분석하여 연도별 결핵 신환발생률, 도말양성결핵 신환율, 진단 지연, 집단발병, 다제내성결핵을 조사하였다. 결과 : 연도별 결핵 신환자 수(10만명당 발생추정치)는 2002년 50명(83.6명), 2003년 42명(83.7명), 2004년 42명(93.5명)이었고 도말양성 폐결핵 신환자 수는 2002년 10명(16.7명), 2003년 11명(21.9명), 2004년 6명(13.4명)이었다. 3년간 도말양성 폐결핵 환자는 31명이 있었고 그 중 12명은 호흡기 증상 발생 30일이 지나서 진단을 받았다. 다제내성 결핵은 2명이 있었으며 결핵의 집단발병이 의심되는 사례는 2차례 있었다. 결론 : 전경대원과 20-29세 연령군 일반인의 결핵 신환발생률, 도말양성 폐결핵 발생률의 통계적으로 유의한 차이는 없었다.

The HBV DNA Amounts in Serum Have No relationship with ALT level and Hetergeneous Population Coexits in Chronic Hepatitis B Virus Infection. Proceedings of International Symposium on East-West Medicine, Seoul. 212-230, 1999. -Hepatitis B is caused by hepadnavirus. Hepatitis B virus replicates through 3.5kb pregenomic RNA intermediate which is regulated by core promoter. Pathogenesis of hepatitis B virus has been bilieved the result of host immune response. But recently many studies have reported that high level of viral replication caused by mutation in core promoter might result in severs hepatitis. But these studies were performed in vitro, not in vivo. So there is yet debate about which factor, viral of host factor, is more important in pathogenesis of hepatitis B virus. So we measured real viral replication level in 204 chronic hepatitis B patients by quantifying HBV DNA from sera by our novel PCR-based more sensitive method, and compared these results with ALT level measured from same sera, which indicates liver cell damage. Surprisingly there are no significant correlation between HBV DNA quantity and ALT level. Then we cloned core promoter region. In SSCP, we found that many viral mutants coexist in one patient. Base on SSCP result, we chose main viral core promoter type in each patients, which is thought to determine overall viral replication level in this patient. Main type of core promoter region of each 41 patients were directly sequenced. And with these we measured promoter activity by luciferase assay system and compared promoter activity with on another. We found tha there were some differences in promoter activity according to core promoter sequences. And we constructed replication-competent viral constructs with core promoter from 41 patients and Transfected these into HepG2 cell and measured HBV DNA by southern blot. There were also differences in HBV DNA quantity according to core promoter sequences. On these all results we investigated correlation between the effect of HBV core promoter on viral replication in vitro and HBN DNA quantity, ALT level from sera of each patients. We found there is no significant correlation among them. As a result, we concluded that in determining severity chronic hepatitis B patients, host factors of each patient is more important rather than replicative activity of virus itself.

플라즈마를 이용한 화학증착법 (PECVD)으로 Corning glass 1737 기판에 Sb-doped SnO2 박막을 증착하였다. 플라즈마 화학증착시 반응변수에 따른 박막의 결정상, 표면형상 및 광투과도를 XRD, SEM, AFM 과 그리고 UV-VIS-NIR Spectrophotometer를 이용하여 분석하였다. Thermal CVD에 비해 PECVD법은 박막의 증착속도를 향상시켰고, 박막의 표면형상을 보다 균일하게 하였다. 반응온도 450℃, 유입가스비 R=1.12, RF power 30W에서 결정성과 광투과도가 비교적 뛰어난 Sb-doped tin oxide films을 얻을 수 있었다. Sb-doped tin oxide films were deposited on Coming glass 1737 substrate by plasma enhanced chemical vapor deposition (PECVD) technique. The films deposited at different reaction parameters were investigated by using XRD, SEM, AFM, and UV-VIS-NIR Spectrophotometer. Compared to thermal CVD,PECVD effectively enhanced the deposition rate and smoothed the surface of tin oxide films. Sb-doped tin oxide films which have a relatively good crystallinity and photo-transmission were obtained at deposition temperature 450℃, input gas ratio R=1.12, and RF power 30W.

본 연구에서는 마우스에 이미 오염된 방사성스트론튬(Sr-85)을 제거하는데 수용성카이토산이 어느정도 효과가 있는지 알아보고자 하였다. Sr-85를 정맥주사한 경우 주사후 1일째의 체내 잔류량은 72.9 ±5.7%, 5일째는 57.7 ±1.9%, 7일째는 54.2 ±1.4%로 서서히 감소하였으며, Sr-85를 복강내 주사한 경우는 주사후 5일째 54.4 ±1.2%, 15일째 50.6 ±0.8%로 정맥주사에 비해 낮은 잔류량을 보였다(5일째 잔류량의 비교, P<0.05), 0.3% 수용성카이토산을 1회 정맥주사해준 제21군 및 10% 수용성카이토산을 식이중에 섞어 먹인 제5군은 각각의 대조군에 비해 체내 잔류방사능의 차이가 없었으나 (P>0.05), 0.3% 수용성카이토산을 3일간 정맥주사한 제3군과 3% 수용성카이토산을 이틀 간격으로 15일간 복강내 주사한 제6군에서는 각각의 대조군에 비해 낮은 잔류방사능을 보였다. (P<0.01). 결론적으로 수용성카이토산을 연속적으로 정맥투여하거나 복강내 투여하는 경우에는 스트론튬의 골대사촉진 또는 골중의 스트론튬과의 반응등을 통해 그 배출을 촉진시킬 것으로 사료되었다. The aim of the present study was to elucidate the effect of the water soluble chitosans on the removal of contaminated radiostrontium(Sr-85) from the bone of mice. The remaining radioactivities in intravenously injected controls(group 1) were higher than in intraperitoneally injected controls (group 4, P<0.01). The % retention at day 5 were 57.7 ±1.9%, 54.4 ±1.2%, respectively. Single intravenous injection of 0.3% water soluble chitosan and continuous oral ingestion of 10% water soluble chitosan for 15 days were ineffective on the removal of contaminated radiostrontiums. Multiple intravenous or intraperitoneal injections of water soluble chitosan effectively removed contaminated radiostrontiums (P<0.01 vs controls). In conclusion, water soluble chitosan might remove once incorporated radiostrontium from bones of mice. further studies were needed to elucidate the mechanism of the removal.

Developement of dance acadamy has not be developed much, content, object and territory of dance academy are not clear as well. Under these circumstances, we need much effort of studys, and need to study of dance in whole territory for developement of dance academy. Especially, theoretical stands of sociology of dance is need immediately under the present society. Social roll and function of dance, and dance roll and function of society are already recognized. These points are dealt in folklore. These phenomena are due to that there were not studies about unique dance studies, and not only qualities of studies but also qualities of studies are not much comparing to other academies. Lately, some of these about dance are published, and dance theorists are growing. In this time, We need to arrange dance field and to take a triangular position in the sociology of dance as a stimulant, confrontation. As more, sociology of dance is required to take a triangular position as one field of sociology to corver all the social area, as soon as revising to pursue only a aesthetical value of dance. So, next are Meannings and assignments of the sociology of dance according needs of sociology needs of sociology of dance standing. Meannings of the sociology of dance standing 1) It will make develope Dance acadamy, and stimulate the groping of the systematic domain of dance. 2) It will popularization of dance, because it can make clear the phase of position of dance in the practical side rather than ideal side. 3) It will easily make sociology of dance to take part in similar study, like dance aesthetics, dance philosophy and art theory. 4) General, objective and scientific criticism will be possible in criticicizing dance, because it adds not only aesethetic objection but also social side. 5) Choreographers can be interested in social problems, because sociology of dance is getting important, therefore deep creation can be achieved. 6) The populace's response can be high after PHASE 5), the recognition about dance can meet new aspects. 7) Rather serious and systematic studies can be proceeded, through considering dance in relation to society. 8) It will offer a chance to sociology of dance to take important position in a curriculum of dance academy. 9) It is very helpful to similar studies, because studies of sociology of dance are related to general studies of all field of society. 10) More social scientific experimentation studies will be developed, which is differed from present comprehensive studies. 11) It will present our dance socioty' direction, moving formore, our socioty'direction also. Assignments of the sociology of dance standing 1) The exact sociology of dance standing should be set up after discussing specific and purpose of dance. 2) Reserching content should be chosen after arrangement of dance conception and selection of research object. 3) Research territory has to be discussed by arrangement of research content. 4) Adaptable research method for sociology of dance has to be studied. 5) It should be studied about thoretical background of sociology of dance and boundary and theory application of sociology. 6) The people studing sociology of dance should be multitudinous. 7) The meeting and institude studying sociology of dance are acutely required and lots of qualitive and quantive research are needful.

Although porous concrete is recently used as a pavement at a parking lot, a public squre and a bicycle road, we use without enough examining. Most the maintenance of quality for porous concrete is only dealt with strength and color tone. Also, there is not et enough fundamental data about dynamical properties for strength, rate of void and water permeability. Even when it is applied to at the scene, it is been a matter. Accordingly in this study analyzed influences through the dynamical properties, combination, and time to vibration. After the analyzation, they investigated peculiar dynamics which are strength of porous concrete, rate of void, and water permeability follow the rate of increase on an admixture making pozzolan reaction. This is purpose to improve capacity of the sidewalk permeable concrete and development of the economical technique for pavement.

A digital satellite communication channel has a strong nonlinearity with memory due to saturation characteristics of the high power amplifier in the satellite and transmitter/receiver filters used in the overall system, and can be well modelled by a nonlinear Volterra series. In this paper, we design and evaluate neural network based adaptive equalizers for compensation of nonlinearities in digital satellite communication channels. We consider CMLP (complex multi-layered perception). CRBFN (complex radial basis function network) and complex ρth order Volterra filter as equalizers, and evaluate their performances in terms of symbol error rate under various noise conditions. In particular, a complex hybrid learning algorithm of k-means clustering and LMS (least mean squares) algorithm is proposed for the CRBFN. Computer simulation results show good performance for all the equalizers considered
