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.

HBeAg 양성인 만성 간염에서 라미부딘 치료전 HBV Core Promoter 서열이 약제내성 발생에 미치는 영향

윤영근,김연수 순천향의학연구소 2004 Journal of Soonchunhyang Medical Science Vol.10 No.1

<Background> Lamivudine is a potent inhibitor of RNA-dependent DNA polymerase of HBV. However its efficacy is limited by emergence of drug-resistant mutant. Mutation of HBV core promoter (CP, T1762 and A1764) is known to be associated with the reduction of transcription of precore mRNA and development of HBeAg-negative phenotype. Therefore, it could be assumed that the CP sequence might influence the responsiveness to antiviral therapy such as lamivudine in HBeAg-positive chronic hepatitis B. This study was carried out to find out if pretreatment CP sequences are associated with the development of lamivudine resistance in HBeAg-positive chronic hepatitis B. <Method> HBV CP sequences were analysed directly from the pretreatment sera of eight patients in whom high level of HBV DNA breakthrough occurred during the treatment, which were compared to those from eight patients who cleared HBeAg without the breakthrough. HBV polymerase sequences were also analysed in the patients with the breakthrough. <Results> Serum HBV DNA level who had the breakthrough was 2653±1459 pg/mL and 1405 ± 403 pg/mL in the patients who cleared HBeAg. All the patients with DNA breakthrough showed YMDD mutation (4 with Met552Val and Leu528Met and 4 with Met550Ile). Among the patients with the breakthrough, baseline CP sequence was wild type (A1762, G1764) in three, A1762 and A1764 in three, and T1762 and A1764 in two patient. On the other hand, among the patients who cleared HBeAg, seven patients(88%) haboured T1762 and A1764 mutation(p=0.018) at pretreatment period. Remaining one patient had wild type CP (A1762, G1764), however precore mutation(A1896) was found in this patient. <Conclusion> It is likely that emergence of lamivudine-resistant mutant or HBeAg seroconversion is influenced by the baseline HBV CP sequence in HBeAg-positive chronic hepatitis B.

In this paper, the simulation models were examined to represent the flow through the plenum chamber in the intake system of MPI spark ignition engine. The constant-pressure perfect-mixing model or branch model which had been devised originally to represent the flow through the manifold branch system was tested. The constant-volume model or tank model also applied and the results were compared with those of the branch model. The prediction accuracies showed no remarkable differences between two models. Therefore, both models would be applicable successfully to represent the flows at the plenum chamber.

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.

For strength and competence of athletes, nutrition is the primary thing to be taken care of followed by the process of training. However, some athletes and coaches focus only on strength, techniques and reinforcement of mental strength whereas they do little care about nutrition. It is desirable that athletes should have a proper knowledge about nutrition, which can help proper training of weight control. To achieve the purpose within limited time, courses that provide training of nutrition and educational materials to increase educational effect should be developed. 1. Education about nutrition in our country is hardly available at schools except students of food and nutrition in universities. 2. People who are interested in weight control focuses on risks of health so that the consider what should be and necessity of weight control. 3. For enhancement of ㎈ory effectiveness, a small quantity of food intake several times per day is recommended for meals. 4. Athletes and coaches must have a full understanding of three performancerelated components such as carbohydrate, fat and protein among six essential nutrients : carbohydrates, fat, protein, vitamin, mineral and water. 5. Weight control through sauna may cause disorder is organism if it goes too far. 6. Coaches must provide regulations that weight control is performed through consistent training and more studies with experiments are necessary. 7. Tonic, vitamin tablets, ginseng, and pepper paste that have been considered to contribute to enhancement of competence have no significant and direct effect on competence. 8. For athletic competition, weight control by reducing body fat is recommended for athletes.
