기능현 전치부 반대교합자의 ACTIVATOR 치료 효과에 관한 임상적 고찰

성재현,전준영,서혜경 慶北大學校 齒科大學 1987 慶北齒大論文集 Vol.4 No.1

The authors treated eight mixed dentiton patients with functional anterior cross-bite by using activator. The lateral roentgenographic cephalograms were analyzed before and after treatment, and skeletal and dental changes following the activator therapy were evaluated. The results were as follows: 1. The mandible was rotated backward and downward. 2. There were labioversion of upper incisors and slight linguoversion of lower incisors. 3. There was little effect of treatment upon maxillary skeletal structures. 4. LFH was increased slightly and soft tissue profile was improved.

Design of a low power 4th-order delta-sigma modulator with single reconfigurable amplifier

성재현,이동현,윤광섭 한국과학기술원 반도체설계교육센터 2018 IDEC Journal of Integrated Circuits and Systems Vol.4 No.1

This paper describes the 4th-order feedback deltasigma modulator with only one amplifier for the application of bio signal processing. The amplifier was reused 4 times by using time interleaving technique. For reducing KT/C noise which most related to integrating capacitance, first and second reused op-amp is designed to load 20pF integrating capacitor and third and fourth is designed to load 1pF and 250fF capacitor each. To solve stability issue made by different capacitance, this paper proposed stage variable op-amp. The modulator was designed with 0.18um CMOS standard process and dissipates the power of 354uW with supply voltage of 1.8V. The measurement results demonstrate the peak SNDR of 72.8dB and the ENOB of 11.8bits with an input signal frequency of 250Hz, a sampling frequency 256kHz, an input signal bandwidth of 1kHz, and an oversampling rate of 128. From measurement results FOM1 is calculated to 49.6pJ/step and FOM2 is calculated to 154.5dB.

성재현,권오원,경희문 慶北大學校 齒科大學 1993 慶北齒大論文集 Vol.10 No.1

This study aimed to find out some guidlines for treatment planning and prognosis prediction of growing Class Ⅲ malocclusion patients. Four patients were selected for this study. Two of them(case 1,2) were sucessfully treated through orthopedic and orthodontic treatment. But during postretention eriod, relapses in dental and skeletal relationships were observed. Other two cases(case 3,4) were not obtained good occlusion through same treatment procedure as mentioned above. Serial Cephalograms, photos, models and health creords(body height) of the cases were analysed in each treatment and observation interval. The changes in skeletal and dental relationship of the patients during early orthopedic treatment, orthodontic treatment and observation periods were evaluated. The results might be summarized as follows. . Initial changes after correction of anterior cross bite in orthopedic phase were lingual tipping of lower incisor, labial tipping of upper incisor and opening of mandibular plane to cranial base. . Two cases(case 1,2) which were obtained good occlusion through treatment showed harmony between the growth of maxilla and that of mandible. . During retention period, the greater mandibular growth than maxillary growth caused the relapses in dental (overjet, overbite, molar relationship) and skeletal relationships. . During retention period, not only the amount of mandibular growth but also the direction of mandibular growth contributed to the change of antero-posterior relationship between maxilla and mandible. . Remarkable mandibular growth continued after pubertal growth spurt of stature. . Even though we had treated succesfully the Class Ⅲ growing patients combined with skeletal and functional factors during active treatment period, we should observe them continuously unitil the end of their pubertal growth spurt. . The authors could recommend to delay the treatment of the Class Ⅲ growing patients involved more skeletally(ex. shape, discrepancy) until end of pubertal growth spurt.

Status of HPV vaccination among HPV-infected women aged 20–60 years with abnormal cervical cytology in South Korea: a multicenter, retrospective study

성재현,류상미,Myeongsu Yoo,이정규,김기순,지영미,조치흠,김석모,홍성란,정대훈,이원철,박종섭,김태진,Mee Kyung Kee 대한부인종양학회 2020 Journal of Gynecologic Oncology Vol.31 No.1

Objectives: Since 2007, human papillomavirus (HPV) vaccines have been administered for the prevention of cervical cancer in Korea. We investigated the status of HPV vaccination among HPV-infected adult women with abnormal cervical cytology before the introduction of National Immunization Program. Methods: From 2010 to 2016, HPV-positive women (age, 20–60 years) with atypical squamous cells of undetermined significance or low-grade squamous intraepithelial lesion (LSIL) were enrolled from five hospitals across Korea. Their HPV genotype, epidemiologic, and clinical data, including HPV vaccination history, were obtained. We compared the epidemiological characteristics and prevalence of HPV-16/18 genotypes between vaccinated and unvaccinated women. Results: Among the 1,300 women, approximately 26% had a history of vaccination. Vaccinated patients were significantly younger, unmarried, and had a higher education level than unvaccinated women. For HPV-vaccinated individuals by vaccine dose, there was a significant younger age at vaccination initiation (p=0.025), longer duration from HPV vaccination to Pap test date (p=0.001), and lower proportion of HPV-16/18 (p=0.028) in the women with three doses. There was a significantly lower prevalence of HPV-16/18 genotypes in women who were vaccinated at least 12 months prior than in unvaccinated women (adjusted prevalence ratio [aPR]=0.51; 95% confidence interval [CI]=0.29–0.88). For women with LSIL, the prevalence of the HPV-16/18 genotypes was significantly lower in women who were vaccinated more than 12 months prior than in unvaccinated women (aPR=0.35; 95% CI=0.13–0.96). Conclusion: This study highlighted the status of HPV vaccination and the prevalence of HPV-16/18 genotypes among HPV-infected women with abnormal cervical cytology according to HPV vaccination. It provides preliminary information regarding the status of HPV vaccination among Korean adult women.

한국과 중국 소비자의 안경의 선호도 차이에 대한 설문 조사 연구

성재현,조은진,김달영 대한시과학회 2018 대한시과학회지 Vol.20 No.4

목적: 이 연구는 안경과 선글라스에서 테와 렌즈의 형태와 색상에 대한 한국인과 중국인 소비자 집단의 선호도 차이를 조사하기 위하여 실시되었다. 방법: 한국에 유학 중인 중국인 학생 150명과 한국인 대학생 150명을 대상으로 설문조사를 실시하고 그결과를 분석하였다. 안경광학 관련 전공자는 설문 대상에서 배제되었다. 중국인 학생들에게는 중국어 간체자로 번역된 설문지를 제공하였으며, 제공된 설문지는 한국 대학 석사과정에 유학 중인 중국인 원어민 학생이 한국어 설문지를 바탕으로 번역한 것이다. 결과: 중국인 소비자 집단은 안경보다 선글라스에서 글로벌 유명 브랜드를 더 선호하였으며, 한국산 안경제품을 상대적으로 선호하는 것으로 나타났다. 또한, 무테 또는 반무테, 금색테, 투톤컬러 렌즈 항목에서 한국인 소비자 집단보다 높은 선호도를 나타냈다. 결론: 이 연구의 결과는 한국 안경 제조․유통 업체의 중국 시장 진출이나 중국인 고객 비율이 높은 안경원의 판매 전략 수립에 기여할 수 있을 것으로 기대된다. Purpose : This survey aimed to investigate the differences in shape and color preference of eyeglasses and sunglasses between Korean and Chinese consumers. Methods : The questionnaire was conducted on 150 Chinese students studying in Korea and 150 Korean college students. Any student who majors in optometry was excluded. Chinese students were provided with questionnaires that were translated into Simplified Chinese characters, and it was translated by a native Chinese student studying in a master course of a Korean university, on the basis of Korean questionnaire. Results : The Chinese consumer group preferred the global famous brand in sunglasses rather than the glasses, and it was found that they preferred the Korean glasses products relatively. Also, they presented higher preference to half- or rimless frame, gold color, two-tone colored lens, comparing to the Korean consumer group. Conclusion : The results of this study are expected to contribute to Chinese marketing strategy of Korean manufacturing․optical shop companies, and to sales strategy of Korean optical shops with Chinese tourists.
