Background and Objectives:A non-progressive and conductive hearing loss with normal eardrum, which has no history of trauma and infection is highly suggestive of a congenital ossicular malformation. Among ossicular anomalies, the most common anomalous ossicle is stapes. However, incus anomaly is sometimes encountered with or without stapes anomaly. The objectives of this study are to describe patterns of incus anomaly, encountered in patients who have a normal eardrum and to analyze their surgical results with special reference to the patterns of incus anomaly. Subjects and Method:We reviewed 26 patients (31 ears) with congenital incus anomaly, which were confirmed through exploratory tympanotomy at Ajou University Hospital from 1994 to 2005. We analyzed temporal bone CT, preoperative and postoperative audiometric findings, and surgical findings. Results: 10 anomalous patterns were detected out of 31 cases of congenital incus anomaly. Incus without its long process was the most common anomalous pattern. In 15 out of 26 cases (57.7%), incus anomaly was associated with stapes anomaly, which was usually unilateral. We could get hearing improvement in 26 out of 31 ears (89.1%). Conclusion:Various anomalous patterns of incus were noted in our series. Incus anomaly was often associated with stapes anomaly, which was usually unilateral. The surgical result of incus anomaly was excellent except the cases without stapes.

Evidence based medicine is the conscientious, explicit, and judicious use of current best evidence in making decisions about the care of individual patients. In terms of benign paroxysmal positional vertigo (BPPV), the costs to the health care system and the indirect costs of BPPV are significant. Despite its significant prevalence, and quality of life and economic impacts, considerable practice variations exist in the management of BPPV across disciplines. In this situation, to educate clinicians on evidence based approach to BPPV would be important. In this article, recent guideline by the American Academy of Otolaryngology Head and Neck Surgery will be reviewed. Korean J Otorhinolaryngol-Head Neck Surg 2012;55:751-6

Two Cases of Acute Mastoiditis with Subperiosteal Abscess

박헌이 대한청각학회 2013 Journal of Audiology & Otology Vol.17 No.2

The incidence of mastoiditis in pediatric age has consistently increased over the last two decades due to increase of antibiotic-resistant bacteria. Compared to young patients, occurrence of acute otitis media complications such as acute mastoiditis and subperiosteal abscess is relatively low in adults. Various treatments for acute mastoiditis with subperiosteal abscess such as tympanostomy tube insertion, intravenous antibiotics, and postauricular incision and drainage have avoided the morbidity and necessity of mastoid surgery. Recently, many studies have indicated mastoidectomy only in cases of severe complications or failure of disease improvement after antibiotic treatment and myringotomy. In this report, we present two cases of successful treatment of subperiosteal abscess and discuss the management of acute mastoiditis with subperiosteal abscess in both child and adult.

Congenital Stapes Anomalies with Normal Eardrum

박헌이,한동희,이종빈,한남수,정연훈,박기현 대한이비인후과학회 2009 Clinical and Experimental Otorhinolaryngology Vol.2 No.1

Objectives. A non-progressive and conductive hearing loss with normal eardrum, but no history of trauma and infection, is highly suggestive of a congenital ossicular malformation. Among ossicular anomalies, stapes anomaly is the most common. The purpose of this study is to describe patterns of stapes anomaly and to analyze its surgical outcome with special reference to its patterns. Methods. We conducted a retrospective case review. The subjects comprised 66 patients (76 ears) who were decisively confirmed by the exploratory tympanotomy as congenital stapes anomalies without any anomalies of the tympanic membrane and external auditory canal. The preoperative and postoperative audiological findings, temporal bone computed tomography scan, and operative findings were analyzed. Results. There were 16 anomalous patterns of stapes among which footplate fixation was the most common anomaly. These 16 patterns were classified into 4 types according to the status of stapes footplate. Successful hearing gain was achieved in 51 out of 76 ears (67.1%) after surgical treatment. Conclusion. Footplate fixation was usually bilateral, whereas stapes anomalies associated with other ossicular anomaly were usually unilateral. The success of the surgical treatment of stapes anomaly might depend on its developmental status of the footplate. Stapes anomalies were detected without any fixed patterns, therefore, it is quite possible to detect a large variety of patterns in future. Objectives.

평가어(Appraisal Systems) 사용에서 나타난 팬자막과 전문가 자막의 비교: 태도(Attitude) 및 강도조절(Graduation)을 중심으로

박헌일 한국통번역교육학회 2014 통번역교육연구 Vol.12 No.3

The purpose of this study is to investigate whether differences exist between fansubs and official subtitles in preserving the factors of Attitude and Graduation, which are the two subsystems of the Appraisal systems. The source text used in this study was a script from House (Season 4: Episode 6), an American television drama series that gained much popularity worldwide. The official subtitles were provided by On Media, a Korean cable provider, and the fansubs were produced by the NSC subtitle team from an online fansubs site. The results show that some of the typical characteristics sited by the earlier studies on fansubs, such as subtitles occupying more than two lines or adding the translator’s commentary to the subtitles for better understanding, no longer apply. However, other features mentioned in previous studies such as prioritizing faithfulness over readability are still prominent as the study shows with statistical significance that fansubs tend to retain more of the Attitude and Graduation resources compared to official subtitles.

한국의 군사통역 품질평가에 대한 고찰 : 통역장교의 평가 결과물 보고

박헌일 한국외국어대학교 통번역연구소 2015 통번역학연구 Vol.19 No.2

The purpose of this study is to investigate the interpreting quality criteria of Korea’s interpreting officers. Firstly, the study surveys 11 interpreting officers in the Korean military to examine which quality criteria are deemed important by the officers. Next, the officers are asked to evaluate recorded videos of interpreting -officer trainees working both from Korean to English and from English to Korean. Finally, the study uses SEM (Structural Equation Modeling) to analyze the interpreting officers’ evaluation of the trainees. The results of the evaluation are then compared with the expectations survey results. Over the years, expectation surveys have shown that professional interpreters regard “content-related” criteria more important than “form-related” or “delivery-related” criteria. Results of this study’s expectation survey are consistent with previous research results: interpreting officers also regard content-related criteria as the most important criteria. However, actual evaluation results show with statistical significance that form-related criteria have higher impact on the total score than any other criteria regardless of interpreting directions. Additionally, the study suggests that delivery-related criteria such as “pleasant voice” and “native accent” have negligible impact on the overall performance score.
