Ear piercing is one of the most frequently performed esthetic operations. However, complications of this procedure such as getting an infection, a foreign body within the wound, can lead to excessive tension which may develop into a hypertrophic scar. Treatment of a hypertrophic scar needs compression but it is difficult to do so with the earlobe. To be effective, a compression device must be uniformed, adjustable, easy to apply, removeable, clean, made from an inert material, light in weight, inexpensive, easy to make, and cosmetically acceptable. We have experienced 47 patients with hypertrophic scars on their earlobes complicated from ear piercing. We thought that using magnetic discs would be the best method for this problem; we were right. Ever since, we have been using magnetic discs for the treatment of hypertrophic scars on earlobes and the results have been satisfying.

The authors presented ‘A study on the knowledge about the field of plastic surgery(I)’ decade ago. Since then, the cognition toward a plastic surgery might be altered by the evolution of internet and social atmosphere taking count of outward appearance. Therefore the authors studied again about the cognition to the plastic surgery. The subjects were total 1812 of high school and college students residing in Seoul, Korea from October through December in 2003 and 1812 students are consisted of 839 male and 973 female. The contents of questionnaire are as follows: 1. The cognition to the plastic surgery. 2. The cognition to the difference between plastic surgery and orthopedic surgery. 3. The cognition to the operation performing in the filed of plastic surgery. 4. The known operation kinds of plastic surgery. 5. The experience of plastic surgery operation. We compared the results of this survey with that in 1992. The results of research showed 15.1% increase in the cognition to the plastic surgery, 5.6% increase in the cognition to the difference between plastic surgery and orthopedic surgery and 9% increase in the cognition to the operation performing in the filed of plastic surgery. In the known operation kinds of plastic surgery, a double-eyelid operation was the most well known and followed by rhinoplasty and augmentation mammoplasty, but in 1992, a double-eyelid operation was followed by rhinoplasty and rhytidectomy. In the experience of plastic surgery operation, the result showed 6.3 %, which has more than doubled in the last 10 years. Increase of the cognition to the plastic surgery is inspired, but that results is localized to aesthetic field.

Efficient Perovskite Optoelectronic Devices Using Conjugated Polyelectrolytes as Multifunctional Passivating and Hole-Transporting Layers

장충현,정의대,박종현,송명훈 한국공업화학회 2020 한국공업화학회 연구논문 초록집 Vol.2020 No.-

The development of optimal charge transport layers for perovskite-based optoelectronic devices is an important research direction to improve the device performance and stability. Optimal charge transport layers should exhibit desirable energy levels for efficient charge extraction while blocking opposite charges and enabling the crystal growth of perovskite layers with suppressed interfacial defects. In this waork, the conjugated backbone and ionic densities of CPEs are modulated and then the relationship between the structures of CPEs and the device characteristics are observed. As the ionic density of CPEs increases, the wettability and interfacial crystal growth of perovskite are improved. The various optical and electrical analytical techniques, including steady-state PL, TCSPC etc. have verified the good defect passivation and enhanced efficiency of perovskite devices with CPEs.

The epiphora is usually distress to the patient not only in physiological aspect but also in psychological aspect. The obstruction of nasolacrimal conduit system, which may produce epiphora can be caused by congenital anomalies, chronic dacryocystitis, after ablation of lower lid carcinoma, trauma and facial paralysis. Especially, severe naso-orbital fracture can be obstructed the bony nasolacrimal canal or total lacrimal conduit system. The epiphora with damage to the nasolacrimal duct will require a dacryocystorhinostomy or conjuntivodacryocystorhinostomy. The conjuntivorhinostomy should be considered in the cases of totally occluded nasolacrimal conduit system, failed dacryocystorhinostomy, or failed conjunctivodacryocystorhinostomy. By using the nasal funnel flap method, the authors performed conjuntivorhinostomy in patients with the obstruction of nasolacrimal conduit system and obtained the following conclusions: 1. The new created lacremal conduit have maintained good patency. 2. None of the patients had significant epiphora and purulent discharge. 3. There are no nasal deformities and operation scars are insignificant. We experienced 3 cases of the nasal funnel flap method and recognized that this technique can provide functional and cosmetical advantages than other conventional conjuntivorhinostomy.

Dentigerous cyst originates from the crown of the tooth has been completely formed by accumulation of fluid between the reduced enamel epithelium and the tooth crown. In the incidence age, dentigerous cyst occur with a more even distribution among the age groups but there is noticeable drop in the patients younger than ten. There is greater incidence of cysts in the maxilla than in the mandible, but dentigerous cysts differ in the respect ; there are found more often in the lower jaw. We experienced 4 cases of dentigerous cysts which is rare in first decade and acquired satisfying result by surgical excision.

Recently aesthetic surgery is widely performed and medical advances made us to understand the public knowledge. But we have few study of public knowledge about aesthetic surgery. So we made an investigation of the knowledge of aesthetic surgery in high school and college students. The survey was conducted to about 7,500 high school and college students in Seoul and small city around Seoul from Jan. to Apr. in 1992. The followings are the results; 1) As to the plastic surgery over 60% of the respondents knew it. 2) As to the aesthetic surgery under 40% of the respondents knew it. 3) As to the aesthetic surgery female knew more well and knewledges about Aesthetic surgery were different in regional and collage course. 4) 95.7% of all respondents wanted Aesthetic surgery was done by specialist. 5) As to the aesthetic surgery over 65% of the respondents approved it. 6) Aesthetic surgery operation was done only 3.1% of respondents

The lips combined with nose, focusing structure which located on the central part of face, are kept in important position functionally and cosmetically. Bilateral cleft lips occupy about 10-15% in all congenital cleft lips and because of short columella and non-protruded nasal tip, they appear severe deformities whose characteristics are distributed nostril and prominent premaxilla. We have been tried many procedures which were classified into straight-line closure such as Veau, Rose-Thompson, Cronin and Manchester method and various flap methods as Skoog, Tennison and Millard method for the correction of bilateral cleft lips. But, there were some advantages and problems each other. We have experienced 25 cases of one-stage closure of bilateral cleft lips by Modified Manchester method, which has improved prominent premaxilla, size of the prolabium with creating adequate central tubercle and obtained consistently a good functional and cosmetic results, from 1974 to 1987. We describe the experience with a review of literatures.

Ota氏 모반의 임상적 고찰

朴炳目,李斗炯,張忠鉉 大韓成形外科學會 1986 Archives of Plastic Surgery Vol.13 No.2

In 1939 Ota presented under the somewhat cryptic title of "Nevus fusco-caeruleus ophthalmomaxillaris" an syndrome consisting of grayish-blue, macular discoloration affecting the sclera of an eye and the ipsilateral facial skin in the area of distribution of the corresponding trigeminal nerve. Ota'a nevus is usually a unilateral, non hairy, macular, but slightly raised, discoloration of the face. Ota's nevus has been reported most often in Orientals, though other races may also be affected. And Ota's nevus was one of the disease which was formed frequently in plastic and reconstructive surgery patients in Korea. Various attempts to treat Ota's nevus were practiced, but they have been uniformly unsuccessful. So Ota's nevus was reviewed, which was treated with excision, cryosurgery (dry ice), dermabrasion skin graft and CO₂LASER surgery from March 1975 to February, 1984 at Kyung Hee University hospital. The conclusions are as follows; 1. With the above methods, complete treatment without scar formation and pigmentation was impossible. 2. LASER surgery was the single method which revealed relatively high satisfactory rate(71%). 3. By combined treatment with LASER and cryosugery increased satisfactory rate (75%).
