Introduction Newborn hearing screening (NHS) program has been implemented to include not only babies with identifiable risk factors for permanent hearing loss but all babies admitted in the wellbaby nursery and neonatal intensive care unit (NICU) in Korea. Evidence to support the expansion of the NHS program continues to collect. Early identification of hearing loss and appropriate intervention aims to assure adequate opportunity to maximize language development and communication for children with hearing loss.1,2)Accurate audiological evaluation of hearing in young babies requires appropriate technology and experienced manpower. For screening purposes, the screening tests should have acceptable range of sensitivity and specificity, and yet be easy to handle for use by various personnel. Automated auditory brainstem response (A-ABR) and otoacoustic emission (OAE) tests are considered as methods of choice for NHS.1) NHS protocols may vary in the choice of the tests and the number of repeated screening tests ("stages") among different institutions.3,4) In the early days of NHS, the test method was recommended to be selected from either OAE or auditory brainstem response (ABR) or both.5,6) Both ABR and OAE tests can identify sensory/cochlear) hearing loss. However, OAE responses may be intact in cases of neural hearing loss (auditory neuropathy/auditory dyssynchrony), that would be identifiable by abnormality in ABR. Since the babies admitted in NICU are more likely to be at risk for neural hearing loss than their counterpart in wellbaby nursery, the current recommendation for NHS testing methods are different for each group. The 2007 position statement of the Joint Committee on Infant Hearing (JCIH) updated the recommendation for test protocols: A-ABR is recommended if a single test method is chosen for screening of NICU babies.1)The aim of this study is to present the outcome of NHS using transient evoked otoacoustic emission (TEOAE) as initial evaluation method in NICU graduates to discuss the necessity of ABR to complement its limitation. Subjects and Methods The clinical data of all babies who were admitted in NICU at the Yonsei University College of Medicine Gangnam Severance Hospital between February 2010 and November 2011 was retrospectively reviewed. All babies were screening using a two-staged NHS program (Fig. 1). TEOAE tests were performed as initial screening method within 2-5 days from birth. If the babies "failed" the initial TEOAE screening, otoscopic examination and second stage TEOAE tests were performed. After the two stages of TEOAE, referred babies were recommended for diagnostic audiological evaluation including ABR. Referral rates were estimated and quality indicators for screening recommended in JCIH 20071) were evaluated. Two qualified audiologists performed testing of neonates. All neonates were screened for hearing impairment using TEOAE within 5days after birth before discharge from the hospital. TEOAEs were recorded using ILO 92 Otodynamics analyzer system (Otodynamics, England, UK) and ILO V6 software. The tests were performed in soundproof audiobooths. A click stimulus with 80 μs duration was presented at a repetition interval of 20 msec. TEOAEs were considered present ("pass") if the signal-to-noise ratio was 6 dB or great in at least 3 of 5 frequency bands, and absent ("fail" or "refer") otherwise. Results During the study period, 149 neonates graduated from NICU and all underwent hearing screening. Initial TEOAE tests were performed within 2-5 days after birth. Fifty out of 149 (33.6%) babies were scheduled for second stage program. However, 9/50 of them were lost to follow up. From initial screening, TEOAEs were absent unilaterally in 33/50 (66.0%) babies, and bilaterally in 17/50 (34.0%)(Fig. 2). In the second stage screening using repeated TEOAE was performed within 1 month of birth, 35/41 (85.4%) babies were "passed" and 6/41 (14.6%) remained "fail" cases. Fro... Background and Objectives: Newborn Hearing Screening (NHS) program aims to identify babies at risk of hearing loss and provide appropriate rehabilitation within the crucial period for language development. The risk of hearing loss in increased in babies discharged from neonatal intensive care unit (NICU) compared to wellbaby nursery. Transient evoked otoacoustic emission (TEOAE) or automated auditory brainstem response tests are utilized. The purpose of this study is to assess the outcome of NHS using TEOAE as initial evaluation method in NICU graduates. Subjects and Methods: TEOAE was performed as initial screening method for NHS in NICU neonates born between February 2010 and November 2011. Babies referred from TEOAE were reevaluated with repeated TEOAE or auditory brainstem response. Referral rates were estimated and quality indicators for screening (Joint Committee on Infant Hearing position statement, 2007) were evaluated. Results: Among 149 neonates graduated from NICU, 50 (33.6%) babies failed initial TEOAE ('refer'). A second stage TEOAE testing was performed in 41 (82.0%) of these babies: 35 (85.4%) passed and 6 (14.6%) were referred for diagnostic testing. From 2-stage TEOAE screening program, 6 neonates were referred for diagnostic audiological evaluation: sensorineural hearing loss was identified in 2 babies and 3 babies were lost to follow up. Quality indicators for screening were as follows: 1) 94.0% of all newborn infants admitted to NICU completed screening by 1 month of age, and 2) 4.0% of all newborn infants who fail initial screening and fail any subsequent rescreening before comprehensive audiological evaluation. Conclusions: Timely and adequate screening of hearing loss is prerequisite for accurate diagnosis and appropriate rehabilitation in infants especially from NICU. Further refinement of the current NHS with additional reliable screening technology is required for more stable and successful screening program.

Due to advancements in display technology and artificial intelligence computing, the technology trend of HMD is moving beyond VR and AR to MR headsets. In this study, we propose a unified detection platform based on virtual/mixed reality using deep learning image recognition technology, which allows simultaneous detection of real and virtual objects in the MR environment without the need for platform switching. After capturing real-world space, 3D virtual objects are displayed in the MR environment, and pre-trained detection weights based on real object data are used to detect both 3D virtual and real objects. The proposed platform operates through a single simulation content approach, enabling seamless detection of real and virtual objects. Pilot tests have confirmed the detection performance of 3D virtual and real objects. The proposed platform is expected to enhance realism and interaction in the MR environment, allowing users to benefit from additional information delivery, collaborative work, and training in various industries. 디스플레이 및 인공지능 컴퓨팅 기술의 발전으로 인해 HMD의 기술 흐름은 VR, AR을 뛰어넘어 MR 헤드셋으로 가고 있다. 본 연구에서는 발전하는 MR 헤드셋의 기술에 앞서 MR 환경에서 객체 검출을 하되 단순히 객체를 검출하는 것이 아니라 실제 객체와 가상 객체를 플랫폼 전환 없이 동시 검출하는 활용방안으로서 딥러닝 영상인식 기술을 이용한 가상/혼합현실 기반 통합 검출 플랫폼을 제안한다. 실 공간을 취득한 후 실 공간에 3D 가상 객체를 띄워 MR 환경에서 실제 객체 기반 데이터로 사전 학습된 검출 가중치를 사용하여 3D 가상 객체와 실제 객체를 검출한다. 제안한 플랫폼은 실제 객체와 가상 객체를 플랫폼 전환 없이 동시에 검출하는 단일 시뮬레이션 콘텐츠 접근 방식에 의해 구동되며, 파일럿 테스트를 통해 3D 가상 객체와 실제 객체 검출 성능을 확인하였다. 제안한 플랫폼은 MR 환경에서 객체 검출을 통해 현실감과 연계 작용을 강화시킴으로써 사용자는 MR 환경에서 산업 현장에서 추가 정보 전달, 협동 작업 및 학습 훈련 등 다양한 분양에서 유용하게 활용할 수 있을 것으로 사료된다.

The ability of to discern distinct sound frequencies is attributed to frequency specificity in various locations in the auditory pathway. The cochlear duct is tonotopically organized along its longitudinal axis so that the basal turn responds to high frequency and the apical turn to low frequency sounds. Since the cochlear duct is comprised of heterogeneous components including sensory hair cells, neurons and other cellular and acellular components, integration of their diverse features is essential for establishment of tonotopicity. Recent studies aim to investigate the molecular mechanisms responsible for the cochlear tonotopicity. Korean J Otorhinolaryngol-Head Neck Surg 2012;55:745-50

Background and Objectives: To report the clinical features of six patients diagnosed with cases of inferior vestibular neuritis based on abnormal vestibular evoked myogenic potential (VEMP) responses with normal caloric test results. Materials and Methods: We retrospectively reviewed 62 patients presenting with dizziness. All patients underwent a battery of audiovestibular testing, including hearing tests, caloric test and VEMP test. Results: Six patients were diagnosed as inferior vestibular neuritis. All patients presented with acute onset of prolonged vertigo. The pure tone audiograms and caloric test results were normal. VEMP response was absent unilaterally,and normal in the contralateral ear. Conclusion: Inferior vestibular neuritis should be considered in patients presenting with acute vertigo, but normal caloric responses. Comprehensive vestibular testing including VEMP is necessary.
