Purpose: Surgery for thyroid gland requires skin incisions that can result in postsurgical neck scar. To overcome this, many surgeons performed a endoscopic thyroidectomy. But, this approach had a some problems. One of postoperative problems, iatrogenic cervical dystonia(CD) may be occurred. At common, CD is defined as a syndrome characterized by prolonged muscle contraction causing twisting, repetitive movements or abnormal posture. Botulinum toxin A(BTA, Botox^Ⓡ, Allergan, Irvine, CA, USA) is well known treatment agent in the treatment of CD. So, the authors applied BTA injection in rare case with iatrogenic CD resulting in endoscopic thyroidectomy. Methods: A 43 - year - old female had operated endoscopic subtotal thyroidectomy in 3 years ago. She had symptoms such as progressive cervical pain, abnormal neck posture, depression, and sleep difficulty. About 1 year later, the patient who had previous myomectomy of the clavicular head of sternocleidomastoid muscle, however, symptoms were not improved. And then the patient received BTA therapy in our department. The 2 units per 0.1 ㎖ solution was administered in a 1 ㎖ tuberculin syringe. Results: The dose of BTA used in the patient was 36 units for vertical platysmal bands, superficially, and 10 units for ipsilateral sternocleidomastoid muscle, intramuscularly. After 2 weeks, additional the dose of BTA used in the patient was 5 points for remained scar bands, superficially. Complications related to injection such as significant swallowing difficulties, neck muscle weakness, or sensory change were not observed. In 9 months follow - up, the patient had a good result was obtained by the method of BTA injection alone. Conclusion: The basic concept is selective denervation for the hyperactive individual muscles and scar bands. We conclude that BTA is an effective and safe treatment for CD despite the iatrogenic and complex presentation of this complication.
Iatrogenic Blepharoptosis after Cataract Surgery
오화영,박은수,김용배 대한미용성형외과학회 2013 Archives of Aesthetic Plastic Surgery Vol.19 No.3
Eyelid complications after cataract surgery can occur including ectropion, entropion and blepharoptosis. Among them, blepharoptosis has been reported at high rate about 13%. Various causes of ptosis after cataract surgery have been reported. We report the case of three patients treated for blepharoptosis after cataract surgery. All these patients received cataract extraction by a local ophthalmology before they visited our clinics. They presented aponeurotic dehiscence, it was graded as partial and underwent surgical correction by levator aponeurosis advancement. The postoperative course was uneventful. Ptosis was corrected and there was no recurrence during the period of follow-up. All three of them were pleased with the final result. Since post-cataract extraction ptosis is frequent but a preventable complication, understanding the causes of ptosis after surgery is very important. That can help a surgeon prevent its occurrence with careful surgical planning.
한국의 산업화와 여성고용구조의 변화 : 1960-2000년대 from the 1960s to 2000s
오화영,이해진 동덕여자대학교 한국여성연구소 2003 젠더연구 Vol.- No.8
Korea that included in the global capital division has accomplished the rapid economic development under the state-led since 1960s. Korean industrialization, based on light industry using women`s labor of the low wage, resulted in feminization of labor` with the beginning of economic development. Women`s labor market relates closely the process of industrialization under the project of economic growth. The purpose of this article is to examine the aspects of such changes in the employment structure of women`s labor. In particular, this article is focused on the changes of women`s labor market, based on the process of the industrial restructuring under the state-led and the global economy. As well, this paper perceives the composition of women`s labor, gendered hierarchies, patriarchy with the capitalism, and the stratified arrangement of women`s labor. In addition, this paper examines how the state has formulated the national labor policy, particularly the labor policy for women, to mobilize women labor for the project of the economic development, and how women workers have coped with difficulties.
하악각 골절에서 제 3 대구치 발치 후 아테로-콜라겐 스펀지의 유용성

Purpose: Fibrillar collagens like type I collagen, are the major constituent of the extracellular matrix and structural protein of bone. Also, it can be a scaffold for osteoblast migration. The purpose of this study was estimated the effects of absorbable atelo - collagen sponge(Teruplug^Ⓡ, Terumo biomaterials Co., Tokyo, Japan) insertion in tooth extraction sites on periodontal healing of the second molar, healing of the fractured mandibular bone and new bone formation of third molar socket after the extraction of the impacted third molar with mandibular angle fracture. Methods: In our study of six cases of mandibular angle fractures, all of them underwent the extraction of the third molar tooth & absorbable atelo - collagen sponge insertion in tooth extraction site. Three of them had a intraoral infection & oral opening to fracture site, two of six had dental caries, and only one had reduction problem due to third molar position. Six consecutive patients with non - comminuted fractures of the mandibular angle were treated by open reduction and internal fixation using one noncompression miniplates and screws placed through a transoral incision. Results: All of the patients have showed good postoperative functions and have not experienced complications requiring second surgical intervention. There was well healing of the mandibular bone and the most new bone formation of third molar socket after the extraction of the impacted third molar with mandibular angle fracture. Conclusion: The results of this study suggest that absorbable atelo - collagen sponge is relatively favorable bone void filler with prevention of tissue collapse, food packing, and enhance periodontal healing. Thus, the use of atelo - collagen sponge and one noncompression miniplate seems to be relatively easy, safe, and effective for the treatment of fractures of the mandibular angle and third molar extraction.
