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.

이 연구의 목적은 세가지 다른 치아 삭제 형태에 따라 제작된 CEREC3 CAD/CAM의 인레이의 변연 및 내면 간극을 비교 평가하는 것이었다. CEREC3 인레이의 제작을 위해 다음의 제시된 방법에 따라 각 군당 10개의 시편을 준비하였다. 제Ⅰ군-기능 교두를 포함하는 전통적 방식의 capping과 shoulder margin, 제 Ⅱ군-교두를 수평으로 평평하게 삭제하는 단순화된 와동 형태, 제Ⅲ군-교두의 완전한 삭제와 shoulder margin을 갖는 가장 단순화된 형태로 세 군의 시편을 제작하였다. CEREC3로부터 제작된 인레이를 대응치아에 접착시킨 후, 치아 교합면의 중심을 지나게 협설면 방향으로 microsaw를 이용하여 절단하였다. 이후 Stereomicroscope을 사용하여 20배율에서 확대 영상을 촬영하였다. 그리고 미리 정해놓은 marginal, axial, angle, horizontal 기준점에서 Leica application suite 프로그램을 사용하여 시편과 치아 사이의 변연 및 내면 간극을 측정하였다. 일원분산분석을 사용하여 같은 기준 지점에서 세 군 사이의 차이를 분석하였으며, 각 군 안에서 여러 지점 사이의 차이 또한 알아보았다. Tukey's test로 95% 유의수준에서 사후 검정하였다. 세 군 모두에서 변연 부위에서 간극이 가장 작았으며, 변연 간극은 제Ⅰ군 80.0-97.8㎛, 제Ⅱ군 42.0-194.8㎛, 제Ⅲ군 51.0-80.2㎛의 범위를 나타내었다. 내면 간극은 제Ⅰ군 90.5-304.1㎛, 제Ⅱ군 80.0-274.8㎛, 제Ⅲ군 79.7-296.7㎛의 범위를 나타냈고 horizontal wall 부위에서 가장 큰 간극을 보였다. CEREC3 CAD/CAM시스템을 사용한 인레이 제작에 있어서 새롭게 제안된 두 가지의 단순화된 와동 형태는 변연 및 내면 간극이 전통적인 교두 피개 와동 형태보다 우수하지 않았다. The aim of this study was to evaluate the marginal and internal gaps in CEREC3 CAD/CAM inlays of three different preparation designs. CEREC3 Inlays of three different preparation designs (n = 10) were fabricated according to Group Ⅰ-conventional functional cusp capping/shoulder preparation, Group Ⅱ-horizontal reduction of cusps and Group Ⅲ-complete reduction of cusps/shoulder preparation. After cementation of inlays, the bucco-lingual cross section was performed through the center of tooth. Cross section images of 20 magnifications were obtained through the stereomicroscope. The gaps were measured using the Leica ap plication suite software at each reference point. Statistical analysis was performed using one-way ANOVA and Tukey's test(α < 0.05). The marginal gaps ranged from 80.0 to 97.8 ㎛ for Group Ⅰ, 42.0 to 194.8 ㎛ for Group Ⅱ, 51.0 to 80.2 ㎛ for Group Ⅲ. The internal gaps ranged from 90.5 to 304.1 ㎛ for Group Ⅰ, 80.0 to 274.8 ㎛ for Group Ⅱ, 79.7 to 296.7 ㎛ for Group Ⅲ. The gaps of each group were the smallest on the margin and the largest on the horizontal wall. For the CEREC3 CAD/CAM inlays, the simplified designs(groups Ⅱ and Ⅲ) did not demonstrate superior results compared to the traditional cusp capping design (group I).

The purpose of this paper is to select 7 male athletes and female athletes of high school, and to compare their active potential differences of upper arm muscles according to characteristic of a racket. the results obtained are as follows: 1. According to the accumulative distribution rate of racket material, graphite and wood material show better efficiency in case of brachio radialis muscle of male athletes, but the racket material shows no constant efficiency in brachii radialis muscle of female athletes. In case of flexor carpi radialis muscle, wood material provides better efficiency only for male athletes. In case of triceps brachii muscle, wood material gives better efficiency to males athletes and steel material gives better efficiency to females athletes. Especially in case of biceps brachii muscle, neither male nor female athletes are influenced by racket materials at impact. 2. In the muscle load rate according to racket material, wood has the highest muscle active potential and graphite has the lowest active potential. Therefore, graphite is thoght to be better in the efficiency of muscle load rate.

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.

In order to improve the disadvantages of the copolymers and the terpolymers for PSA uses, quarterpolyrners were synthesized and crosslinked. Poly(butyl acrylate-co-2-ethyl hexyl acrylate-co- methyl methacrylate-co-2-hydroxy ethyl methacrylate) (BA/2-EHA/MMA/2-HEMA) and Poly(butyl acrylate-co-2-ethyl hexyl acrylate-co-methyl methacrylate-co-acrylic acid) (BA/2-EHA/MMA/AA) have superior PSA properties compared to the copolymers and the terpolymers. The best performances of BA/2-EHA/MMA/2-HEMA as a PSA were measured when benzoyl peroxide initiator was used with the reactant mixture comprised 80% of BA and 2-EHA, 15% of MMA, and 5% of 2-HEMA. The optimum reaction temperature and time were 80℃ and 8 hours, respectively. For BA/2-EHA/MMA/AA, the best performances were obtained when the polymerization was performed at the monomer composition of BA and 2-EHA, 15% of MMA, and 5% of AA. BPO was used as initiator and the optimum reaction temperature and time were identical to those of BA/2-EHA/MMA/ 2-HEMA. Isocyanate and melamine were used to crosslink BA/2-EHA/MMA/2-HEMA and BA/2-EHA/MMA/AA, respectively. No effect of type of cross-linking agent on the peel adhesion was observed with aging. The quarter-polymers crosslinked with melamine left residues on the counter surface after weathering resistance test whereas the polymers crosslinked with isocyanate did not.
