Background: Postoperative scars following cleft lip surgery are frequently accompanied by cosmetic and functional problems; therefore, patients with cleft lip scars usually undergo various long-term scar treatment courses. Currently, only a limited number of fractional laser treatment cases of cleft lip scars have been reported. Objective: This study aimed to evaluate the safety and efficacy of the combination laser treatment for hypertrophic scar management following cleft lip surgery. Methods: This single-center retrospective study included 27 patients who underwent cleft lip surgery before 12 months of age. The control group comprising 13 patients received only a silicone gel or sheet for the scars, while the treatment group comprising 14 patients underwent laser treatment with a 1,550 nm non-ablative fractional erbium-glass laser, followed by a 10,600 nm ablative fractional carbon dioxide laser. Intralesional triamcinolone injection (5∼10 mg/mL) was administered immediately after laser treatment. Scar improvement was assessed at 1, 3, and 6 months after surgery using the Vancouver Scar Scale. Results: The mean total Vancouver scar scale showed a statistically significant improvement in the treatment group compared to that in the control group. In the sub-analysis of pigmentation, the vascularity, pliability, and height significantly improved in the treatment group. No differences in the patients’ baseline characteristics between the two groups were noted. No significant adverse effects were observed during the follow-up. Conclusion: Combination laser therapy using fractional lasers and intralesional triamcinolone injection is safe and effective for managing cleft lip surgery scars in infantile patients.

이주희,김제민,이상규,최수연,이주희,이영인,김지희 연세대학교의과대학 2023 Yonsei medical journal Vol.64 No.12

Purpose: Fractional microneedle radiofrequency (FMR) systems are used to treat inflammatory acne and scarring. Nonetheless, few controlled studies have combined this treatment with the traditional ablative fractional laser (AFL). We aimed to assess the safety and efficacy of the combination of FMR and AFL versus AFL alone in treating acne and acne scars. Materials and Methods: In this 20-week, randomized, split-face study, 23 Korean patients with facial acne and acne scars under went FMR and AFL treatments. One half of each patient’s face was randomly assigned to receive FMR+AFL, whereas the other half received AFL alone. Treatments were administered in three consecutive sessions at 4-week intervals. This study investigated the severity of inflammatory acne, acne scars, individual lesion counts, depressed scar volumes, as well as patient and physician satisfaction. In addition, five patients underwent skin biopsy, and sebum output was measured. Results: The FMR+AFL treatment demonstrated superior efficacy compared to AFL alone in terms of inflammatory acne and acne scar grading, lesion counts, and subjective satisfaction. The side effects were minimal and well-tolerated in both groups. Immuno histochemical findings from skin biopsy samples revealed that the application of FMR+AFL could induce an inhibitory effect on sebum secretion at the molecular level. Conclusion: FMR combined with AFL is a well-tolerated and effective treatment modality for inflammatory acne and acne scarring.

Syringoma: A Clinicopathologic and Immunohistologic Study and Results of Treatment

이주희,장재용,이광훈 연세대학교의과대학 2007 Yonsei medical journal Vol.48 No.1

The purpose of our study was to describe clinical and histopathological features of sixty one patients with histological diagnosis of syringoma over four year period in our dermatology clinic in Korea. Female:male ratio was 6.6:1 with onset of age during 2nd and 3rd decades in more than half of the patients in our study. The most frequently involved site was eyelids (43 cases, 70.5%) and the most common color of lesion was skin-color (30 cases, 49.2%). In 34 cases, characteristic tad-pole appearances (55.7%) were observed. Basal hyperpigmentation was observed more frequently in brown- colored lesion (p=0.005). Fibrosis was observed more frequently in erythematous lesion (p=0.033). Keratin cyst was observed less frequently in genital involved group (p=0.006). We also performed immunohistochemical stain for the presence of progesterone receptor (PR) and estrogen receptor (ER) in fifty six cases with negative results.

This study investigates the relationship among Career Decision, Career Preparation Behavior and MBTI Type of the college student. The subjects of the study are 259 D university students. Kim & Sim's questionnaire(1990) on personality type, Go's questionnaire(1992) on career decision level and Kim's questionnaire(1997) on career preparation behavior are used. The results are as follows: (1) The career decision level changes in accordance with the personality type. The differences between 'I' type and 'E' type, 'J' type and 'P' type are statistically significant(p<,001 ). (2) The career preparation behavior level changes in accordance with the personality type. The differences between 'I' type and 'E' type, 'J' type and 'P' type are statistically significant(p <.01). (3) The career preparation behavior level and the career decision level change in accordance with the age(school year) of the college student. (4) The career preparation behavior level changes in accordance with the sex. (5) The career decision level are correlated to the career preparation behavior level.

음악 스트리밍 서비스 시장의 가격 유형 전략 분석

이주희,서영덕 한국문화예술경영학회 2018 문화예술경영학연구 Vol.11 No.1

디지털 음악 스트리밍 서비스 시장은 계속 성장하고 있으며 그에 따라 경쟁이 치열해지고 있다. 그러므로 스트리 밍 서비스를 하는 업체들은 다양한 서비스의 전략이 필요하다. 그 중에서도 가격 유형 전략은 가장 중요한 전략이다. 현재 국내의 음악 스트리밍 서비스는 유료의 가격유형을 중심으로 서비스를 하고 해외 음악 스트리밍 서비스의 경우 는 무료를 중심으로 발전한 후 무료와 유료의 가격 유형 서비스를 하고 있다. 해외의 음악 스트리밍 서비스 업체가 국내에서 서비스를 하게 되었을 때 국내 업체와 해외 업체의 가격 유형을 어떻게 결정해야 할지에 대한 분석이 필요 하다. 본 연구에서는 가격 유형 전략을 1)광고 기반을 둔 무료, 2)정액제를 바탕으로 둔 유료, 3)무료와 유료의 두 유형 이 결합된 형태인 결합(유료+무료)으로 구분하여 게임이론을 적용하여 분석한다. 주요 결과는 다음과 같다. 결합(유료 +무료) 유형이 불가능할 경우, 국내 업체와 해외 업체가 선택하는 전략(균형)은 둘 모두 무료 혹은 (국내 업체 무료, 해외업체 유료)가 내쉬균형이다. 결합 유형이 가능하다면, 국내 업체와 해외 업체 모두 결합 유형을 선택하는 것이 내쉬균형이다. This paper provides a mathematical model of music streaming service's price types. We will investigate and analyze price types of Melon music streaming service and Spotify music streaming service through game theory. For the sake of convenience, it is assumed that 1) price types of service is based on ‘free, ad-supported service’, ‘paid service’ and ‘both’, 2) consumers prefer ‘free, ad-supported service’ to ‘paid service’, 3) if Melon and Spotify have same price types, consumers prefer Melon to Spotify, 4) if consumers can choose between ‘paid service’ and ‘free, ad-supported service’, they prefer ‘paid service’ to ‘free, ad-supported service’. It is shown that if Spotify launches its service in Korea, Melon and Spotify have should choose price types which is free, paid and both(free and paid). It is because of “Nash Equilibrium” which is the best outcome from a choice.
