Purpose: To investigate the outcome of frontalis suspension surgery congenital blepharoptosis with poor levator palpebral muscle function using preserved fascia lata with direct tarsal and frontalis fixation method. Methods: Twelve congenital ptosis patients (fourteen eyes) who underwent frontalis suspension using preserved fascia lata with direct tarsal and frontalis fixation method between July 1999 and June 2002 with the mean follow-up time of 54.8 months (31 months~78 months) included. And the postoperative results were obtained from medical records retrospectively. Results: The desired lid height was achieved in eight out of twelve patients (71.4%) after surgery. In four patients (4 eyes) (28.6%), adjustment was required due to under-correction within one month postoperatively. At a mean follow-up period of 54.8 months, all twelve patients had good final results with no postoperative complications. Conclusions: Frontalis suspension using preserved fascia lata with direct tarsal and frontalis fixation method provided cosmetically pleasing results with a low rate of ptosis recurrence and complication related to procedures. This method using preserved facia lata could be considered as alternative to the use of autogenous facia lata for the repair of ptosis.

목적: 출생 후 만 1∼12년의 미숙아들을 대상으로 굴절이상과 이와 연관이 있는 인자들을 알아보고, 정상 만삭아와 비교해 보고자 하였다. 대상과 방법: 1994년부터 2004년까지 본원에서 출생한 37주 미만의 미숙아 중 출생 후 만 1∼12년 후 추적관찰한 환아를 대상으로 하였다. 조절마비굴절검사와 안축장길이, 전방깊이를 측정하였고 의무기록을 통해 재태기간과 출생체중을 후향적으로 조사하였다. 미숙아망막병증으로 치료받은 미숙아군(1군), 치료가 필요하지 않았던 미숙아군(2군), 만삭아군(3군)으로 분류하여 비교하였다. 결과: 대상 환아는 모두 86명이었다. 근시의 정도는 미숙아(1+2군)에서 통계적으로 유의하게 높게 나타났으며 1군과 2군을 비교했을 때도 1군에서 통계적으로 유의하게 높게 나타났다. 대상환아 중 근시 환아들을 대상으로 나이를 보정하여 안축장 길이 및 전방의 깊이를 비교하였을 때 세 군 간에 유의한 차이가 없었다. 근시를 나타낸 1군 환아들에서 근시의 정도에 유의하게 상관관계를 보였던 인자는 안축장의 길이, 전방의 깊이, 재태기간, 및 출생 시 체중이었다. 결론: 출생 후 만 1∼12세의 미숙아들에서 굴절이상 양상 및 영향인자를 알아보았다. Purpose: To evaluate the refractive status and their relation with gestational age and factors influencing the occurrence and degree of myopia in premature infants. Methods: Premature infants with a gestational age <37 weeks and born between Sept. 1994 and June 2004 were enrolled, and subdivided into two groups according to treatment for threshold ROP: Group 1: children born prematurely with threshold ROP, Group 2: children born prematurely without threshold ROP. Cycloplegic retinoscopy and ultrasound biometry were performed. These results were compared to the full term babies (Group 3). Results: There were significant differences in the incidence of myopia between age of 4 to 6 among the three groups, and the degree of myopia was higher in premature infants born with threshold ROP than the others. There were no significant differences in the axial length and anterior chamber depth between group 1 and 3. The degrees of myopia in group 1 were related to birth weight, intrauterine period, and axial length. Conclusions: Laser or cryotherapy treated eyes were significantly more myopic than the others. The degree of the myopia was found to be related to the birth weight, axial length, anterior chamber depth, and intrauterine period. Premature infants should be screened regularly and long-term follow up should be recommended to prevent amblyopia, strabismus, and other ocular abnormalities.

This article reports an attempt to perform a similarity analysis on a collection of 25 culinary manuscripts in Chosun periods using a set of quantitative text analysis methods. Historical culinary texts are valuable resources for linguistic, historic, and cultural studies. We consider the similarity of two texts as the distributional similarities of the functional components of the texts. In the case of culinary texts, text elements such as food names, cooking methods, and ingredients are regarded as functional components. We derive the similarity information from the distributional characteristics of the two key functional components, cooking methods and ingredients. The results are also quantified and visualized to achieve a better understanding of the properties of the individual texts and the collection of the texts as a whole.
