Space in the film is expressed by a variety of different forms of meaning and furthermore space could be the reason in the presence of a work. space in the film plays a important roll of tasks in making up the area of the screen image and sound over the visual space through sound consists of auditory space. sound has its own screen composition techniques that generate an idea of adding space in space, as well as in the surrounded existing through amalgamate a foe space to a visual image. In production’s aspect, it is very important in sound configuration that an ambience of stems in term of expressing film sound, makes people to concentrate in storytelling. sound, the configuration of ambience is to relocate the two-dimensional space into the three dimensional space. this reproduces the overall expression of images and realistic nature. there are many kinds of sound system, however none of these are excludable. people may think all of these difference stem’s components are recognized through psycho-acoustic system. although an ambience gives understanding of psycho-acoustic system, people can be disturbed if a main idea of configuration is different from the image. Many scenes in the film make the decisions by using the continuity of sound. discontinuity of scenes often happens in low budget featured films, or student films due to the different size of pictures and disharmony of ambience. In order to have the power of persuasion in spatial sound in the film, it is important to acquire the audience’s perception by efficient operation system, arrangement and design. this study was designed to discuss the ambience in sound system. This paper is written to describe the sound system by stems. it will analyze theories specifically for ambience and detail relationship between visual and sound in the film 〈Gravity〉.despite to other movies,〈Gravity〉 has been praised for using whole new different realistic visual and sound effect that people have never experienced in the field of cinematic spacious and it received sound award and sound editing award in Academy Award 2013. 〈Gravity〉has contributed a lot in the field of ambience analysis and this paper will talk about the technical and artistic parts of the research and discussions in the special sound.

청주 명암동유적 발굴조사 성과와 의의

성재현 한국고고미술연구소 1998 동원학술논문집 Vol.1 No.-

국립청주박물관은 청주시 동부우회도로 건설공사 구간에서 확인된 유적에 대해 1998년 5월 26일부터 7월 31일까지 약 2개월 동안 긴급수습조사를 실시하였다. 청주 명암동 유적(淸州 明岩洞 遺蹟)은 조사결과 삼국시대부터 근세에 이르기까지 지속적으로 분묘가 조성되었고, 삼국시대에는 주거공간으로 이용되었던 것으로 밝혀졌다. 특히, 청주지역에서는 처음 확인된 삼국시대의 수혈주거지(竪穴住居址)는 당시 주거지 형태와 그 입지에 대한 새로운 자료라 할 수 있다. 한편, 교란된 지표 채집품 중에는 진천 산수리 요지(鎭川 山水里 窯址)에서 나타나는 토기들도 있어 인근지역인 청주 송절동 고분군(淸州 松節洞 古墳群)과 신봉동 고분군(新鳳洞 古墳群) 사이의 공백을 메워준다는 점에서 중요한 의미를 지닌다고 평가된다. 고려묘는 당시의 무덤 형태 및 축조방법에 대해 새로운 자료라 생각된다. 또한 1호 고려묘에서 출토된 먹은 우리나라에서 처음으로 확인된 고려시대 먹이라는 점에서 주목된다. 이 먹에 쓰여 있는 “단산오(옥)(丹山烏(玉))”이라는 명문 가운데 단산은 지금의 충북 단양으로, 단산은 고려 현종 9년(1018년)부터 충숙왕 5년(1318년)에 단양군(丹陽郡)으로 승격될 때까지 사용된 단양의 구 명칭이다. 문헌사료와 발굴자료의 일치를 보여준다는 점에서 이 먹의 학술적 가치는 매우 크다고 할 수 있다.

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.

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.

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.
