  • Fibroma of the tendon sheath is a benign slow-growing fibrous tumor. Although rare, cases occurring in the upper extremities usually involve the fingers. It appears as a well-defined, roundor oval-shaped mass originating from the flexor tendon. Abundant fibrous stroma makes fibromas appear as a low intensity mass in all MRI sequences. Most of the fibromas manifest as painless soft tissue masses. Herein, we report a case of fibroma of the tendon sheath with an unusual clinical presentation, triggering carpal tunnel syndrome during wrist movement.

  • 쌀의 영양성분은 단백질(7%), 지방질(1%), 당질(80%), 조섬유(0.4%), 회분(0.5%)으로 되어 있으며, 인체 내에서 당질은 열량 공급원으로, 조섬유는 식이섬유 공급원의 역할을 한다. 그리고 무기질로는 인, 칼륨, 칼슘, 마그네슘, 나트륨, 철분 등이 포함되어 있다. 벼에는 약 38종의 병해가 발생하는데 생육시기, 재배장소, 기후 등 환경이나 품종에 따라 달리 나타나며 벼 생육중기 이후에 발생하는 주요 병해는 다음과 같다.

  • Neurogenic tumors are the most common posterior mediastinal tumors and accounting for $19{\sim}39%$ of all mediastinal tumors and 75% of all posterior mediastinal tumors. Neurofibromatosis is an autosomal dominant disorder with variable expression of tumors, including neurologic tumors of the peripheral nerves, nrve roots, and plexi. A posterior mediastinal neufibroma in neurofibromatosis patients is rare. We report here a case of posterior mediastinal neurofibroma in a patient with type 1 neurofibromatosis.

  • Solitary fibrous tumors (SFTs) commonly arise from the pleura and are mostly benign. However, they may develop anywhere in the body, and 10%-30% are malignant. Classically, SFTs appear as solitary enhancing masses, and bilateral presentation is extremely rare. In this case, an 88-year-old male presented with back pain and a history of chronic tuberculous empyema. Imaging studies revealed bilateral paravertebral masses with aggressive radiologic features, which were speculatively presumed as thoracic malignancies in association with chronic empyema. Herein, we report a unique case of bilateral paravertebral malignant SFTs that were accurately diagnosed with a CT-guided coaxial needle biopsy.

  • 본논문에서는 강섬유 철근 콘크리트 보(SFRC) 의 감쇄 거동에 대해서 실험적인 방법과 수치 해석적인 방법으로 연구를 수행하였다 SFRC는 보다 향상된 에너지 소산능력으로 일반 철근 콘크리트보에 비하여 뛰어난 감쇄 거동을 보인다. 감쇄거동은 종방향 철근비강섬유의 형태와 부피 콘크리트 강도 응력 수준등에 의해 영향을 받는다 SFRC보의 감쇠는 다양한 수준의 균열상태에서의 동적실험 데이터를 통하여 평가하였다 곡률과 감쇠의 관계식에 기초한 유한요소 프로그램(TICAL) 이 개발되었으며 0.44%의 강섬유를 혼입한 보의 경우 5-35%의 감쇠비 증가를 보였다

  • 카이토산(chitosan)은 항미생물성, 무독성, 인체적합성 및 양이온성 등의 특성을 지니며 항균, 방취, 보습, 생체적합성 및 생분해성 등의 다양한 기능을 나타내고 있는데, 이를 바탕으로 카이토산을 단독 또는 다른 천연섬유재료와 복합화시키는 연구가 행해지고 있다. 본 연구에서 선택한 카이토산과 복합체를 형성할 수 있는 성분인 견 피브로인(silk fibroin)은 17 종의 아미노산으로 이루어진 단백질로서 의류용 및 의료용 재료로서 이용되고 있는 고급섬유재료이다. (중략)

  • Fibrosing mediastinitis is a rare disease which is characterized by excessive fibrosis of mediastinum and symptoms caused by compression and obstruction of mediastinal structures. Although the pathogenesis of this disease is unknown, granulomatous infection is cinsidered to be the most common cause of this disease. Histoplasmosis is the most common etiology, especially in the endemic areas in United States. Tuberculosis is another etiology of fibrosing mediastinitis. We experienced two cases of fibrosing mediastinitis associated with tuberculous infection.

  • Chondromyxoid fbroma (CMF) is a rare, benign tumor of the bone that represents fewer than $2\%$ of all benign tumors of bone. CMF is most often found in the long tubular bones, especially the tibia and femur near the knee joint. Less common sites included the pelvis, fibula, calcaneus and rib. A 54-year-old male patient presented to us with history of swelling and mild, intermittent local pain without any rise in overlying skin temperature in lateral portion of left 7th rib for one-month duration, which was diagnosed as benign rib tumor by plain chest X-ray and CT scan, and treated successfully by excision of rib with good result. Pathologic diagnosis of this tumor was CMF. Without any medical therapy, there was no evidence of recurrence after operation. We report this case and follow-up of the patient.
