Hyun Soo Kim, Jong Woon Cheon, Min Su Kim, Chang Kil Jung, Kyung Rok Kim, Jae Won Choi, Dong Woo Kang and Sun Young Kim1 Departments of Internal Medicine and Pathology1, DongKang Medical Center, Ulsan, Korea Actinomycosis is a chronic suppurative disease and caused by Actinomycosis species, principally Actinomyces israelii, which are part of the normal inhabitant on the mucous membrane of the oropharynx, gastrointestinal tract, and urogenital tract. It usually affects cervicofacial, thoracic and abdominal tissue. Cervicofacial type has the highest percentage of occurrence with 50%. Actinomycosis frequently occurs following dental extraction, jaw surgery, chronic infection or poor oral hygiene. It may also be considered as an opportunistic infection in immunocompromised patients such as malignancy, human immunodeficiency virus infection, diabetes mellitus, steroid usage or alcoholism. But, actinomycosis rarely occurs in adults with normal immunity and rare in the esophagus. We report an unusual case of esophageal actinomycosis which was developed in a patient with normal immunity and improved by therapy with intravenous penicillin G followed oral amoxicillin, and we also reviewed the associated literature.

아스팔트 콘크리트의 고온변형저항 특성 측정방법 개발

김광우,이문섭,김중렬,이순제 강원대학교 부설 석재복합신소재 제품연구센터 2002 석재연 논문집 Vol.7 No.-

본 연구는 정하중하에서 아스팔트 혼합물의 소성변형 저항특성을 측정할 수 있는 새로운 시험방법을 개발하기 위하여 수행되었다. 2가지 골재(편마암, 화강암)와 6가지 아스팔트(일반아스팔트, 5가지 개질 아스팔트)를 사용하여 총 12개의 밀입도 혼합물을 제작하였다. 마샬 배합설계를 통해 최적아스팔트 함량을 구하고, 결정된 최적아스팔트 함량으로 마샬공시체(S=10 cm)와 자이레토리 공시체(S=15cm)를 제작하여 마샬안정도시험, 휠 트랙킹 시험, 개발된 김테스트(Kim -test)를 수행하였다. 김테스트는 공시체와 하중봉을 지지할 수 있는 김시험장치(Kim tester)를 이용하여 하단이 반경(r) 0.5 또는 1.0cm로 원형절삭한 직경(D) 3cm, 4cm의 하중봉을 사용한다. 또한 재하는 마샬 하중재하 장치를 사용하여 공시체를 60℃ 수조에 30분동안 수침시킨 후 실시되었다. 정하중은 공시체의 직경방향이 아닌 축 방향으로 50 mm/min가 가해졌고, 최대하중(P_max)과 수직변형(y)이 측정되었다. 마샬안정도시험과 간접인장강도시험에서 얻어지는 것과 유사한 곡선이 각각의 시험에서 얻어졌다. 강도값은 P_max, r, y 및 H(=D-2r)을 이용한 K_D=4P_max/π(H+2√(2ry-y^2))^2식을 통하여 계산하였고, 이를 변형강도(kgf/㎠)로 정의하였다. 실험결과, 공시체 직경이나 골재종류보다는 하중봉과 하중봉 하단의 원형처리 여부가 K_D와 P_max 값에 영향을 미치는 것으로 나타났다. 통계분석결과에서 K_D가 소성변형 깊이와 동적 안정도에 높은 상관성을 보였다. 향후 연구를 통해 K_D의 유효성이 검증된다면, Kim-test는 아스팔트 혼합물의 소성변형 저항성을 판단할 수 있는 시험방법으로 사용될 수 있을 것이다. This study dealt with developing a new approach for finding properties which might represent rut resistance characteristics of asphalt mixture under static loading. Two aggregates, a normal asphalt (pen 60-70) and 5 PMAs were used in preparation of 12 dense-grade mixtures. Marshall mix design was used in determination of the optimum asphalt content (OAC) and each mixture at the OAC was prepared for a newly-developed Kim test on Marshall specimen (S=10 cm) and gyratory specimen (S=15cm), and for wheel tracking test. Kim test used Marshall loading frame and the specimen was conditioned for 30min at 60℃ before loading through Kim tester, and apparatus consisting of a loading column and a specimen and column holder. Diameter (D) of column was 3cm and 4cm with each column having different radius (r) of round cut at the bottom. The static load was applied at 50mm/min in axial direction of the specimen, not in diameteral direction, and the maximum load (P_max) and vertical deformation (y) at the maximum load point were measured. A curve, similar to the one from a Marshall test or static indirect tensile strength test was obtained from each test. A strength value was calculated based on the P_max, H(=D-2r). r and y by using the equation K_D=4P_max/π(H+2√(2ry-y^2))^2 and is defined as deformation strength (kgf/㎠). The values of P_max/y and K_I=K-D/y were also calculated to see if these have any correlation with rutting. In general, D and r were significant factors affecting K_D, while specimen size was not. The statistical analyses results showed the K_D had the best correlation with rut depth and dynamic stability. The next best correlation was found from P_max which was followed by P_max/y and K_I in order. Therefore, K_D can be used for selecting the highly resistable asphalt mixture against permanent deformation.

Objective: This study was carried out to investigate if the measurement of range of motion(ROM) could be applied in the diagnosis of Myofascial Pain Syndrome(MPS) and to determine the severity by analyzing ROM in MPS patients. Methods: The study subjects were 476 female telephone number information service workers. Southampton Protocol and Pittsburgh Protocol were used to diagnose MPS and to measure ROM. ROMs were measured by 2 inclinometers exercising each shoulder passively and actively in 5 directions ; abduction, forward flexion, extension, external rotation, and internal rotation. Results: Compared to the normal group (n=147), the mean of right side ROM in the subjects (n=270) with same side MPS was 2.1˚ (SD=11.5) lesser in active extension and 1.7˚ (SD=10.4) lesser in passive extension. Compared to the mild group (n=210), the mean of right side ROM in the patients with same side severe MPS (N=58) was lesser in all directions. Especially in active forward flexion, passive forward flexion, active extension, passive extension and active external rotation, ROM in the subjects with severe MPS was lesser by 6.5˚ (SD=13.1), 5.1˚ (SD=12.8), 5.9˚ (SD=11.8), 5.0˚ (SD=10.6) and 3.9˚ (SD=9.8), respectively, than those of the subjects with mild MPS. Compared to the subjects with left side mild MPS(n=172), ROM in the subjects with left side severe MPS (n=59) was 5.3˚ (SD=13.3) lesser in active forward flexion. Conclusions: In this study, ROMs in the subjects with severe MPS tended to be lesser than those in mild patients. This tendency was more prominent in the right side than the left, active range of motion than passive and forward flexion and extension than others. The results of this study are expected to help diagnose shoulder MPS and determine severity.

배경: STS의 발생에 대해서 다양한 원인이 알려져 있으며,손상과 이물질도 그 원인으로 알려져 있으나 그 발생 증례는 매우 드물다. 저자들은 금속단판 절단원에서 지속적인 손상과 금속 이물질로 추정되는 물질과 관련성을 보이는 ES 증례를 경험하였기에 문헌고찰과 함께 보고하고자 한다. 증례: 환자는 17년간 금속단판 절단원으로 근무하였다. 작업 도중 지속적으로 작은 금속파편에 손바닥을 찔렸으며,작업 중에 금속파편이 손에 박혀 있어 퇴근 후에 매일 제거하였다. 2004년 3월에 손바닥에 종괴가 촉지되었으며, 2006년 11월에 수부 X-ray에서 이물질과 종괴가 발견되어 제거하였다. 종괴는 ES로 진단받았으며 환자가 사용했던 모든 금속봉에는 크롬과 니켈이 함유되어 있었다. 결론: 증례와 같은 이물질 및 손상과 관련을 보이는 STS 특히 ES은 매우 드물며,이물질에 의해 자주 노출되고 손상을 받는 근로자에서 육종이 발생했을 때,그 작업관련성을 의심하여 볼 필요성이 있다. Background: Soft tissue sarcoma is a rare condition with many causative factors. However a soft tissue sarcoma from a metallic foreign body and injury is rare. We report a case of a soft tissue sarcoma caused by a metallic foreign body and injury. Case: The patient had been worked as a metal cutter for 17 years. While working, his palms were constantly pricked by small metallic splinters, which were generally removed after work. On march 2004, he had palpitated mass on his right palm. On November 2006, a right hand x-ray showed a mass and metallic foreign body at the 1st volar space which was confirmed to be an epitheloid sarcoma. All metallic products of his workplace contained chromium and Nickel. which are known to cause soft tissue sarcomas. A review of the literature revealed foreign-body and injury induced oxidative and nitrative stress to be associated with a developing sarcoma. In addition, Cr and Ni are associated with the development of sarcoma. Therefore it was concluded this case ofepitheloid sarcoma was associated with his employment. Conclusion: A soft-tissue sarcoma associated with a metal foreign-body and injury is rare and their relationship is difficult understand. If a case of sarcoma is encountered on a metal associated worker, their job association should be considered.
