외상성, 혹은 선천적 결손으로 인한 함몰부에 사용한 자가 유리지방 이식은 잘 알려진 방법이다. 이를 위해 사용되는 주된 공여부는 복부나 둔부의 피하지방이었다. 그러나, 1977 년 Egyedi는 협지방대를 유경피판으로 처음 사용하였다. 협지방대는 안면골 절단술시, 협측 피판을 들어올릴 때, 혹은 이하선관 수술 같은 구강내 수술시 항상 귀찮은 구조물로써, 수술 시야를 방해한다. 협지방대는 매우 세밀한 막으로 둘러싸인 소엽형태의 볼록한 물질로, body와 네 개의 prccess들로 구성된다. 이 돌기들은 여러 근육층 사이의 충전물로 작용하며, 유아에서는 sucking시 보조작용으로, 성인에서는 윤활재로 사용되기도 한다. 본 교실에서는 협지방대를 사용하여 세 증례의 협골 함몰부에, 그리고 한 증례의 비순구 재건을 위해 사용한 바, 양호한 결과를 얻었기에 문헌고찰과 함께 증례보고를 하는 바이다. The use of the autogenous free fat is a well-known procedure to fill in superficial depressions resulting from the traumatic or congenital defects. The major donor site for this procedure was the abdominal subcutaneous fat or buttocks. In 1977, Egyedi was the first to report the use of the buccal fat pad as a pedicled graft. The buccal fat pad is a structure usually considered to be a nuisance when encountered in intraoral procedures such as facial bone osteotomies, elevation of buccal falp, or procedures on Stensen's duct. In these operations, appearance of the buccal fat pad complicates surgical exposure. The buccal fat pad is a lobulated convex mass of fatty tissue covered by a very delicate membrane, and is described as having a body from which four processes extend. These projection serve as a filling material between the various muscular structures in the area. Recently malar depression was augmented with the pedicled buccal fat pad in 3 cases, and it was used for the reconstruction of the nasolabial fold in one case.

Dematomyositis is an idiopathic inflammatory myopathy characterized by specific skin manifestations and progressive symmetric proximal muscle weakness. Importantly, dermatomyositis is occasionally associated with the internal malignant tumor, which is clearly correlated with poor prognosis. We report two cases of dermatomyositis, showing characteristic skin lesions, that associated with small cell lung cancer in a 64-year old man and gallbladder cancer in a 54-year old man, respectively. On laboratory findings muscle enzymes and liver function markers were elevated prominently. We tried to treat these patients with systemic corticosteroid and chemotherapy. The patient with small cell lung cancer died of SAH due to head trauma and in the case of the patient with gallbladder cancer, the symptoms of the muscle weakness and the skin lesions are getting better and worse repeatedly fluctuating and regular periodic follow up is required.

Silmazine(R) cream is an antibiotic agent widely used in burn therapy. It consists of Propylene glycol, Stearyl alcohol, Isopropyl Myristate, Sorbitan mono-oleate, Methyl-p-hydroxybenzoate, Polyoxyl 40 stearate and varseline. A 24-year- old female presented with well-demarcated erythematous papules and vesicles with an itching sensation on the dorsal area of her right hand. She had applied Silmazine(R) cream on the dorsal area of her right handfor 4 days and the skin lesion became aggravated. A patch test with Silmazine(R) cream `as is` showed a positive reaction and propylene glycol and stearyl alcohol, ingredients in Silmazine(R) cream, revealed a positive reaction. These two agents are known as weak sensitizers that can produce allergic contact dermatitis. There are some reports of allergic contact dermatitis from propylene glycol and stearyl alcohol used topically. As far as we know, there are no reports of allergic contact dermatitis from propylene glycol and stearyl alcohol in the Silmazine(R) cream (Silver sulfadiazine) that is commonly used as topical antibiotic medication for burns. We report this rare case of allergic contact dermatitis from propylene glycol and stearyl alcohol in Silmazine(R) cream (Silver sulfadiazine). (Korean J Dermatol 2009;47(6):710∼713)

Diffuse neurofibroma is an uncommon subtype of neurofibroma that occurs principally in children and young adults. It is most common in the head and neck region and appears clinically as a plaque-like elevation of the skin. A 3-year-old girl presented to our hospital with a complaint of skin-colored elevated plaques with hair on her lower back since birth. An ultrasonogram showed several 5∼10 mm sized subcutaneous hypoechoic nodules with increased vascularity. The histopathologic examination revealed ill-defined, uncapsulated infiltrative, spindle shaped cells within the dermis and subcutaneous tissue. Immunohistochemical examination with antibodies to S-100 protein showed positive. We report a rare case of diffuse neurofibroma with hair. (Korean J Dermatol 2009;47(6):696∼698)
보라성게 ( Anthocidaris crassispina ) 의 연령과 성장

The growth of the purple sea urchin, Anthocidaris crassispina, has been investigated using reproduction plates as a character of the age determination. The samples were collected on the coast of Daepo, in the southers part of Cheju Island from August, 1996 to July, 1996. Monthly growth of test diameter mainly occurred from December to March. The obvious growth, however, were not observed between April and lune which seemed to be the resting period. This resting period well corresponded to the time of annual ring formation which was estimated from the analysis of the marginal growth rate. The growth curve fitted well with Bertalanffy equation: L_t=46.65(1-e^(-0.283(t+9.210))), W_t=44.90(1-e^(-0.283(t+9.210)))³

Improving software product quality is a key to increasing user satisfaction and to achieving competitive edge. There are two approaches to assure high software product quality; development process-oriented and product-oriented. There have been many efforts for improving software quality through process certification, for example, CMM, ISO 9000 family, ISO/IEC 12207, SPICE and Bootstrap. However, a good process alone cannot guarantee good product quality. A need for the evaluation of software product quality by an independent third party is growing rapidly for several reasons. We are concerned with an application of Statistical Quality Control (SQC) to the evaluation of software product quality to obtain the efficiency of evaluation processes and the objectivity of evaluation results. Methods for selecting test cases using a random sampling approach have been discussed and methods for selecting acceptance criteria with respect to software product quality have also been suggested.
