Glomus tumors of the lung are rare benign neoplasm, originating from modified smooth muscle cells. The patients are usually presented with no or non-specific symptoms such as cough, dyspnea or hemoptysis. Although surgical treatment is considered as the treatment of choice, the endobronchial therapy can be applied to the patients who are unfit for surgical excision. Herein, we describe two rare cases of glomus tumor originated at large airway (trachea and main bronchus) without respiratory symptoms and review their characteristic radiologic, macroscopic and pathological features.

One of the major requirements in preventing Work-related MusculoSkeletal Disorders(WMSDs) is to know definitely what vigorous exertion requirements are contained in a job. This requires improved job analysis tools which can accurately evaluate potentially harmful stresses to the musculoskeletal system. But to simply evaluate the level of stress at a joint, or in a muscle is not enough to motivate job changes. Therefore, the development of ergonomic evaluation tools for the jobs are important to ergonomics. The main objective is compared of the results that made by the ergonomic evaluation tools (e.g., BRIEF and RULA) in actually shoes manufacturing. These were developed in the foreign. So, it is priory needed to research of the ergonomics about Korean characteristic work by physiology and biomechanics.

A multi-parameter neuro muscular electrical simulator (NMES) system was developed to be used to find the optimal parameter condition in obtaining maximum muscle power and minimal fatigue. Since the performance of NMES is mainly determined by the characteristic of its output-stage circuit, we implemented 3 different circuits and compared output characteristics of them. Three amplifier circuits are; 1) a resonant switching converter, 2) a linear amplifier with a transformer, and 3) a step-up DC/DC converter with a high-voltage linear amplifier. Experimental results showed that the step up DC/DC converter with a high-voltage linear amplifier has the best performance.

Nicolau syndrome is a rare complication of intramuscular injection consisting of ischemic necrosis of skin, soft tissue, and muscular tissue that arises locoregionally. The characteristic pattern is pain around the injection site, developing into erythema, a livedoid dermatitis patch, and necrosis of the skin, subcutaneous fat, and muscle tissue. Three patients were injected with drugs (diclofenac sodium, ketoprofen, meperidine) for pain relief. Three patients complained of pain, and a skin lesion was observed, after which necrosis developed on their buttocks. Each patient underwent debridement and coverage. The wound healed uneventfully. We report three cases of Nicolau syndrome in the buttocks following diclofenac intramuscular injection.

Large-scale deletions of mitochondrial DNA(mtDNA) have been documented in patients with mitochondrial myopathies and seem to be especially frequent in patients with Kearns-Sayre syndrome (KSS). About one third of all patients shows a 4,977 bp deletion, known as the "common deletion", that removes a segment of DNA that includes several genes encoding for respiratory chain subunits. In this disorder, the population of deleted mtDNA molecules coexists with population of normal, wild-type full length mtDNAs, a situation known as heteroplasmy. We have performed polymerase chain reaction (PCR) on paraffin-embedded muscle tissues from two korean KSS patients. The PCR analysis revealed the existence of two amplified fragments, the deleted fragments, the deleted fragment of 123 bp characteristic for common deletion and the wild-type fragment of 152 bp.of 152 bp.

Stabismus refers to a muscle imbalance that results in improper alignment of the visual axes of the two eyes. It may be divided into paralytic and nonparalytic strabismus. Paralytic strabismus is primarily a neurologic problem ; nonaralytic strabismus is more strictly an ophthalmologic problem. Characteristic clinical disturbances result from lesions of the third, fourth, and sixth cranial nerves. Lesions of the sixth nerve result in a paralysis of lateral or outward movement and a crossing of the visual axes. We present a case of paralytic strabismus in 24-year-old female who recovered by Oriental medicine, including acupuncture and herbal medicines.

A 5-year-old, castrated male, Maltese was presented with history of acute flaccid paralysis. The dog was presented with sudden loss of muscle tone and involuntary movements of hind limbs. Neurologic examination revealed reduced postural reaction in the bilateral hind limbs. MRI of brain showed moderate hydrocephalus, but other examination results were normal. Based on the characteristic episodes and examination results, canine cataplexy was suspected. Treatment was initiated with clomipramine as cataplexy control. Clinical signs resolved with 3-month medication. This case demonstrates therapeutic diagnosis of cataplexy. To the author's knowledge, this is the first report of cataplexy treating with clomipramine.

Achalasia는 식도의 확장을 동반하는 탐도분문부의 비기질적폐색을 이르키는 질환으로 그 원인은 불명하나 식도하부괄약근의 이완장애와 식도체부에서의 정상연동운동의 결여로 나타나는데 원래 근육신경계의 기능장애의 하나로 중추신경계통의 병변으로 신경 신경절 및 근육의 변성을 이르켜 생긴다는 설이 유력시되고 있다. 주요증상은 연하장애 음식물토출 및 심와부 동통등이다. 저자들은 43세 여자에서의 achalasia 1례를 치험하였기에 문헌적고찰과 함께 보고하는 바이다.

일반적인 홍채 인식 방법은 홍채 근육이 형성하는 고유 패턴에 기초하여 사용자를 식별한다. 홍채의 주요 기능은 자연광의 양에 따라 동공의 크기를 제어하는 것이다. 그러므로 홍채 패턴은 조명 조건의 변화에 따라 팽창 및 수축한다. 홍채 패턴의 변형에도 불구하고 강력한 인식의 정확도를 보장하기 위해 이전의 연구에서는 홍채 근육은 선형적으로 변형된다고 가정하여, 홍채의 트랙을 선형적이고 균일하게 할당하였다. 그러나 홍채 패턴은 실제로 특정 홍채 근육의 복잡한 움직임으로 인해 비선형적으로 변형된다. 이러한 문제점을 극복하기 위해 Dynamic Warping 방법을 사용하여 비선형성을 고려한 새로운 매칭 방법을 제안한다.

We determined the effect of caponization on the carcass and giblet characteristics, and skin and muscle color in Taiwan country chicken cockerels. Caponized birds were surgically altered at 10 weeks old and were fed growing and finishing diets ad libitum during an eighteen-week experimental period. The results showed that the percentage of dressing, heart, feet, thigh, head and neck were significantly (p<0.05) higher in the intact birds, while the capons had a higher (p<0.05) percentage of abdominal fat, intestine, back, wing and breast. Eviscerated weight, breast width, gizzard, liver and spleen ratios were not affected by the treatments. The breast skin color values for lightness (L*) and yellowness (b*) values in the capons were significantly (p<0.05) higher than in the intact birds, but the thigh and back skin were not significantly（p>0.05）different. Compared with the intact birds, the capons had a significantly (p<0.05) less redness (a*) values in the back skin, but were not significantly (p>0.05) different in the breast and thigh skin. The L* value of the thigh muscle was significantly (p<0.05) greater in the capons than in the intact birds, but were not significantly (p>0.05) different in breast and back muscles. The b* values in the breast, back and thigh muscles of the capons were significantly (p<0.05) greater whereas the intact birds had a higher (p<0.05) a* values in the breast, back, and thigh muscles. Moreover, our findings also indicate that the castration resulted in a significant alteration in dressing percentage, carcass region and organ percentage.
