        한국인에서 성인 외비 사진 계측치의 성별, 연령별 비교

        정윤미,장진순,전병훈,최익수 대한비과학회 2008 Journal of rhinology Vol.15 No.2

        Background and Objectives:Rhinoplasty has been frequently performed for correction of injured nose or cosmetic reasons. Korean standard values are insufficient, and most reference values are based on Caucasian ones. We measured Korean values of external nose with photographs according to sex and age. Materials and Methods:Three hundred forty seven subjects without past history of operation or trauma were included in this study. With scaled instrument for head fixation, frontal and profile views were taken. On frontal view, physiognomic face height and nasal width were measured. On profile view, midface height, nasal height, alar height, glabellar depth, nasion depth, nasal dorsum depth, nasal tip depth, nasal depth, nasofrontal angle and nasolabial angle were measured. And location of nasion and shape of nasal dorsum were also classified. Result:Physiognomic face height decreased with age in both men and women groups. Nasofrontal angle increased with age in men. Nasion was located between upper end of upper eyelid and lateral canthus in most cases. On classifying the shape of nasal dorsum, straight type was the most in both men and women groups. Conclusion:We could know average measurements of external nose and differences of those according to sex and age in Korean adults. And it is thought that these data will be useful to facial plastic surgery including rhinoplasty.

        '스콜라' 이용 시 소속기관이 구독 중이 아닌 경우, 오후 4시부터 익일 오전 7시까지 원문보기가 가능합니다.

        IT 기술의 급속한 발달과 더불어 교통정보에도 첨단매체를 통한 교통정보의 제공이 급속히 증가하고 있고 교통정보의 내용도 점차 다양화되고 있다. 그러나 이러한 교통정보와 제공매체의 다양화에도 불구하고 지금까지 교통정보를 제공하는 방법은 대부분이 공공기관의 교통관리측면에서 제공되고 있고 이용자 개개인의 맞춤형 정보를 제공하지 않기 때문에 일반 이용자의 정보에 대한 만족도를 극대화하기 어렵다. 이러한 관점에서 볼 때 웹기반 교통정보는 개인별로 차별화된 교통정보를 제공할 수 있고 다양한 이용자의 요구사항을 만족시킬 수 있는 새로운 형태의 정보제공매체라 할 수 있다. 웹기반 교통정보는 교통정보를 웹을 바탕으로 구현하여 이용자가 사전지식과 경험을 바탕으로 정보를 검색하여 원하는 내용을 얻는 것으로 이용자가 직접 검색하고 교통정보를 게시하는 것은 이용자의 참여를 의미하며, 이는 교통시설과 교통수단을 이용하는 사전지식으로서 활용되어 교통서비스에도 영향을 미칠 수 있다. 여기에 Wibro, 무선랜, USN(Ubiquitous Sensor Network) 기능을 가진 내비게이션이나 PDA, 휴대폰을 이용한다면 교통정보를 언제, 어디서나, 누구나 제공받는 것이 가능해 진다.

        숫자간간격과 반응방식에 따른 이분숫자청취검사의 수행력

        정윤미,장현숙 한국청각언어재활학회 2015 Audiology and Speech Research Vol.11 No.3

        The purpose of this study aimed to investigate appropriate parameters for clinical use by measuring effects of inter-digit-intervals (IDIs) and response modes on the dichotic 3 digit test. The dichotic 3 digit tests were performed in four different IDI conditions (500, 750, 850, and 1,000 ms) in free-recall response mode and in three attention modes (Free recall, Precued Rt or Precued Lt) with a 750 ms IDI appearing in a performance of 70%. Twenty adults, 10 males and 10 females with normal hearing sensitivity participated. The results of this study were as follows: first, the dichotic 3 digit recognition performance was increased as IDI increased from 500 ms to 850 ms and decreased as IDI increased from 850 ms to 1,000 ms. Second, performances by response modes in 750 ms condition were measured that score of ear which was given cue were higher than opposite ear. Recognition scores of Free-recall, Precued-Rt, and Precued-Lt conditions were 69.00%, 93.75%, and 72.00% for the right ear and 65.75%, 64.75%, and 83.75% for the left ear, respectively. Also, ear advantages appeared 3.25% REA, 28.00% REA, and 11.75% LEA in Free-recall, Precued-Rt, and Precued-Lt conditions, respectively. Performances were also higher in Precued-recall conditions than in Free-recall condition. The results revealed that dichotic 3 digit recognition scores changed by IDIs and response modes. It showed that the 850 ms in IDI in free-recall mode was a useful parameter clinically applicable in dichotic 3 digit test. Moreover, the 750 ms paradigm of IDI and Precued recall of response modes can be useful in clinical setting.

        초등 영어 교육에서 수업 내용을 재구성한 영어 연극의 효과

        정윤미,이혜경 미래영어영문학회 2014 영어영문학 Vol.19 No.4

        The purpose of this study is to investigate the effects of play activity on student's cognitive and affective abilities through the reconstruction of lessons in elementary school English. The study was focused on teaching English listening and speaking of 3rd graders. The play activity is one of the teaching methods which young learners of English can improve their listening, speaking ability and develop their confidence and interest in learning English. The findings of this study are as follows. First, both the students' listening and speaking abilities have improved. After the play activity was implemented to the class, the overall average English listening and speaking abilities were found to be better than before. Second, students gained confidence and developed a greater interest in learning English through the play activity in the English classroom. Through the practice and performance of the play, the students gained far more interest and self-confidence, especially in the area of conversing in English.

        이하선에서 발생한 혈관육종 1예

        정윤미,강윤경,장진순,최익수 대한이비인후과학회 2008 대한이비인후과학회지 두경부외과학 Vol.51 No.9

        Angiosarcoma is an exceedingly rare and highly malignant neoplasm which develops from the endothelium of blood vessels. Only a few cases of primary angiosarcoma of the non-irradiated parotid gland have been reported. In this case, we report a primary angiosarcoma of the parotid gland in a 64-year-old man without prior irradiation of the head and neck region. MRI finding revealed a 3.9×2.7 cm sized mass located in the right parotid gland with unhomogenous enhancement in T2 weighted image. The patient underwent a total parotidectomy and radical neck dissection. The histologic diagnosis was high-grade angiosarcoma showing pleomorphic spindle or epithelioid tumor cells growing as solid infiltrative pattern or slit-like irregular vascular lumina formation. Despite postoperative radiation therapy, the patient died of lung metastasis with hemorrhage 3 months later. (Korean J Otorhinolaryngol-Head Neck Surg 2008;51:838-41)

        후각신경세포의 손상 및 재생 연구모델의 융합연구

        정윤미,박종수,김철희,유관희 한국융합학회 2016 한국융합학회논문지 Vol.7 No.2

        후각기관은 주변 환경의 다양한 화학물질을 감지하는 기관으로 생존, 종족번식에서 감정에 이르기까지 다양하고 중요한 역할을 하고 있다. 유전적, 환경적 등 다양한 요소에 의해 후각장애가 발생할 수 있으며, 일시적인 경우에는 약물치료 등으로 회복될 수 있지만, 신경세포에 문제가 생긴 영구적인 손상의 경우는 치료가 어렵다. 따라서, 신경세포의 사멸을 억제하거나 재생을 유도하는 치료제의 개발이 필요하다. 본 연구에서는 후각신경세포 특이적으로 GFP 형광단백질을 발현하는 형질전환동물을 제작하여 생체 내 후각신경세포를 관찰하고자 하였다. 또한, 다양한 화학물질을 처리하여 후각신경세포 손상을 인위적으로 유도할 수 있는 방법을 고안하였고, 후각신경세포의 손상 및 재생 과정을 실시간으로 모니터링하였다. 본 연구를 통해 확립된 후각신경세포의 손상 및 재생 모니터링 시스템은 향후 후각신경세포 재생 메커니즘 연구 및 치료제 개발에 유용하게 사용될 것으로 기대된다. The olfactory system is an important model for the study of neuronal degeneration and regeneration, including neuronal diseases. When the olfactory sensory neurons are damaged by nerve injury or are exposed to environmental factors, they degenerate and are replaced by regenerating neurons. To monitor neuronal degeneration in living animal, we established an olfactory-specific GFP transgenic zebrafish. The effects of Triton X-100 or sodium acetate on the olfactory system were examined. A significant decrease in the number of GFP-positive olfactory sensory neurons was observed after chemical lesion. We found a recovery of GFP-positive neurons by 2 days posttreatment. From these results, we expect that further studies of olfactory degeneration and regeneration using this transgenic zebrafish will provide important advances for the study of neuronal degeneration and regeneration.
