An epidermal cyst, also known as an epidermoid cyst or epidermal inclusion cyst, is the most prevalent type of cutaneous cyst. This non-cancerous lesion can appear anywhere on the body, typically presenting as an asymptomatic dermal nodule with a visible central punctum. In the case presented herein, an epidermal cyst with uncommon features was misdiagnosed as a lymphatic malformation based on preoperative magnetic resonance imaging (MRI). A 61-year-old man came to us with a swollen left cheek that had been present for 11 months. The preoperative MRI revealed a 3×3.8×4.6 cm lobulated cystic lesion with thin rim enhancement in the left masticator space. The initial differential diagnosis pointed toward a lymphatic malformation. We proceeded with surgical excision of the lesion via an intraoral approach, and the specimen was sent to the pathology department. The pathological diagnosis revealed a ruptured epidermal cyst, indicating that the initial diagnosis of a lymphatic malformation based on preoperative MRI was incorrect. Epidermal cysts located under the muscle with no visible central punctum are uncommon, but should be considered if a patient presents with facial swelling.

Objective : The purpose of study is to define the term Dong(動) in diagnosis view. Method : To define term Dong(動), I refer to Korean, Chinese, Japanese dictionary and Todo Yoshimasu (吉益東洞)'s writing, Yakucho(藥徵) Houkyoku(方極). Next, I search for the diagnosis definition of Dong(動) in 11 case reports. Results : The diagnosis definitions of Dong(動) are two meanings. One is objective symptoms which are doctor can examine, trembling, movement, etc. The other is subjective symptoms which are patient's feeling, emotional problems, etc. It seperates 6 meanings concretely. Conclusions: (1) visible moving of a focus, (2) movement of a focus, (3) appearance of abnormal secretion, (4) abnormal change of focus, (5) feel like moving, (6) change of emotion beyond patient's control. 1~4 are objective symptoms which are doctor can examine, and 5~6 are subjective symptoms which are patient's feeling.

Orthopaedic medicine was developed and published by James Cyriax, a British Orthopaedic Physician on 1929. Orthopaedic medicine is concerned with the diagnosis and treatment of soft tissue lesions. These disorders affect a substantial proportion of all patients in general and in particular, physiotherapy and sports clinics. In broad terms these disorders em trace conditions. such as arthritis. rheumatism. fibrositis. backache. lumbago, sciatica, frozen shoulder, tennis elbow, strained wrist, sprains, aches, inflanmation and sports injuries generally. The soft Moving tissues share one thing in common - they are all radiotranslucent and the tissues in question are the joint capsule, the ligaments, the fasciae, dural sheath. These structures can cause pain but none of them is visible on the radiograph. Dr. Cyriax divided all soft tissues into two basic types : 1) Contractile tissue, 2) Inert or noncontractile tissue. The mechanism of diagnosis is tension applied manually. The physician subjects each tissue about the incriminated joint to tension in turn which they call 'Selective tension' with Cyriax's assessment, a more definitive diagnosis can be obtained and proper treatment can be implemented.

자외- 가시선 흡수분광광도법을 적용하여 주상변압기 절연유의 판정기준을 제시하였다. 절연유가 열화하면 절연유의 전기적 특성치가 저하할 뿐만 아니라 흡광도값도 변하게 된다. tan$\delta$와 절연파괴전압과 같은 전기적 특성치를 흡광도값과 비교하여 흡광도값에 의한 절연유의 판정기분을 설정하였다. 흡광도값이 0.580 이하는 양호, 요주의는 0.580~0.900, 불량은 0.900이상이다. 자외-가시건 흡수분광광도법은 절연유의 열화분석에 적용할 수 있으며, 기존의 육안에 의한 절연유 검사 방법을 대체할 수 있을 것으로 기대된다. 그러나 분광광도법을 현장에 적용하려면 저렴하고 경량화된 휴대용 분광광도계의 개발이 필요하다.

노후 된 콘크리트 사회기반시설 구조물의 활용성 증대와 수명의 연장을 위하여 여러 가지의 보수보강 방법이 시행되어지고 있으나 최근에는 시공이 용이하고 보강효과가 좋은 탄소섬유시트를 활용하는 방법이 널리 쓰여지고 있다. 탄소 섬유로 보수보강을 할 경우 강도가 증진되고 강성이 향상되어 좋은 방법으로 알려져 있으나, 철근 콘크리트에 비해 연성이 떨어져 파괴 시 취성 파괴의 형태를 보일 수 있다, 그리고 보수보강된 구조물을 보강재로 인하여 크랙의 진전을 맨눈으로 확인하기가 어려워지게 된다. 따라서 구조물의 취약함을 드러내는 시기인 보수보강시 광섬유센서를 내장케 하여 취성파괴를 감시하고 구조물의 거동을 모니터링함으로써 안전한 구조물이 되도록 할 수 있다. 이를 위하여 본 논문에서는 광섬유센서를 이용하여 모재와 보강재의 구조거동을 분석하였으며, Peel out 효과라 불리는 계면 파괴현상을 효과적으로 자기진단 할 수 있음을 입증하였다.

In order to extend the life time of building and civil infra-structure, nowadays, patch type carbon sheets are widely used as repairing meterials. Repaired concrete columns and beams with carbon sheets gain their stiffness and strength, but they lose toughness and show brittle failure behaviors. Usually, the cracks of concrete structures are visible with naked eyes and the status of the structure in the life cycle is estimated with visible inspection. After repairing of the structure, crack visibility is blocked by repaired carbon sheets. Therefore, structural monitoring after repairing is indispensible and self diagnosis method with optical fiber sensor is very useful. In this paper, peel-out effects is detected with optical fiber sensors and the strain difference between main structure and repaired carbon sheets when they separate each other.

The facility diagnosis technique of past subjective judged the technical expert and interpreted stably mainly. The facility the periodical civil official becomes indispensability consequently with the law and the system and objectivity inspection which relates with a this and development of diagnosis technique were necessary. Currently the evaluation elements which relate with an inspection and diagnosis technique depended to the subjectivity of each facility quality, data statistics, diagnosis know-how, various circumstance and the technical expert and the evaluation item came to decide. But the evaluation score distribution of marks of each item depended plentifully in data analysis result and experience. The past method is weak in logically because the objection theoretical background and basis are insufficiency. Consequently in order to apply a data analysis result and an experience logically, it used AHP(Analytic Hierarchy Process) method from this research. It is visible with the fact that the application result reconfirmation and complement process will be necessary the technique which is suitable in the multi facility management. Also it is expected with the fact that the application characteristic from the next relation technique will be excellent.

진단이나 인체 모델의 형성에 있어서 필수적인 의료 영상의 분할(Segmentation)은 정확성을 얻기 위해 대부분 수작업에 의해 수행되고 있다. 하지만 수작업은 많은 시간이 소비되며, 같은 영역을 재분할했을 때 동일한 결과를 얻기가 어렵다. 이를 해결하기 위해 본 논문에서는 사용하기 편리하면서 수작업의 정확성을 유지할 수 있는 반자동화된 영상 분할방법을 제안한다. 제안된 방법은 먼저 사용자로부터 분할하고자 하는 영역의 경계에 해당하는 제어점을 몇 개 입력받고 제어점들간의 최소 비용 경로를 연결하여 외곽선을 획득하는 Live-wire를 수행한다. 하지만 Live-wire는 톱날 모양의 외곽선을 형성하거나 영역의 침식을 발생시키므로, 이러한 문제점을 해결하기 위해서 획득된 분할 영역의 외곽선을 재설정시킨 후 이것을 장벽으로 사용하여 SRG(Seeded Region Growing)을 수행하였다. 제안된 User-steered balloon방법은 Live-wire의 문제점을 해결할 뿐만 아니라, SRG가 성장시 새어나가는(Leakage) 문제점도 해결할 수 있다. 본 논문에서는 제안된 방법을 가지고 Visible Human의 다리 근육에 대한 분할을 수행하여 제안된 방법을 검증하였다.

Fibromyalgia (FM) is a contested illness with ill-defined boundaries. There is no clearly defined cut-point that separates FM from non-FM. Diagnosis of FM has been faced with several challenges that occur, including patients' health care-seeking behavior, symptoms recognition, and FM labeling by physicians. This review focuses on important but less visible factors that have a profound influence on under- or over-diagnosis of FM. FM shows different phenotypes and disease expression in patients and even in one patient over time. Psychosocial and cultural factors seem to be a contemporary ferment in FM which play a major role in physician diagnosis even more than having severe symptom levels in FM patients. Although the FM criteria are the only current methods which can be used for classification of FM patients in surveys, research, and clinical settings, there are several key pieces missing in the fibromyalgia diagnostic puzzle, such as invalidation, psychosocial factors, and heterogeneous disease expression. Regarding the complex nature of FM, as well as the arbitrary and illusory constructs of the existing FM criteria, FM diagnosis frequently fails to provide a clinical diagnosis fit to reality. A physicians' judgment, obtained in real communicative environments with patients, beyond the existing constructional scores, seems the only reliable way for more valid diagnoses. It plays a pivotal role in the meaning and conceptualization of symptoms and psychosocial factors, making diagnoses and labeling of FM. It is better to see FM as a whole, not as a medical specialty or constructional scores.
