Objectives : The purpose of this study is to report the effect of east-west medical combined treatment of sudden sensorineural hearing loss(SSNHL) through cooperation in a hospital. Methods : We treated three patients diagnosed as SSNHL by combination of herbal medicine, acupuncture, pharmoacupuncture, moxibustion, cupping, laser therapy and conventional medications. We evaluated the results of this treatment with pure tone audiometry, word recognition score(WRS), the changes in distortion product otoacoustic emissions(DPOAE) and visual analogue scale. Results : One of them showed a meaningful improvement in the hearing level of the low frequency region. The others showed 'Complete recovery' in pure tone audiometry and WRS. The subjective symptoms including tinnitus and ear fullness improved in three patients. Conclusion : This study suggests that east-west medical combined treatment is effective on SSNHL patients.

We investigate whether the association between management overconfident tone and the level of audit effort measured by audit fees and hours differs depending on the level of earnings management. Prior studies suggest that firms led by overconfident managers are likely to initiate risky investments, report low quality financial statements, and have material weaknesses in internal control system. These characteristics, combined together, result in higher audit risk. At the same time, auditors assess audit risk based on the quality of financial reporting, measured by level of earnings management. As a result, the assess audit risk is likely to reflect the combined effect of management overconfidence and the level of earnings management. In this paper, we investigate whether auditors differentiate the effects of real earnings management (REM) and accrual-based earnings management (AEM) when they assess the audit risk related management overconfident. Using the CEO's letter published in 2018, we measure the CEO's tone representing the degree of overconfidence (i.e., activity). Based on this measure, we find that the positive association between managerial overconfident tone and audit effort is more pronounced as the level of REM is higher. However, we find that the baseline association does not vary depending on the level of AEM. These results suggest that auditors consider the managerial overconfident severer when such characteristic accompany the higher level of REM, which can be outcome of aggressive business decisions possibly leading to the higher audit risks. We further find that these results are stronger for Big 4 auditors and continuing auditors. This paper contributes to the literature and practice as follows. First, we provide contextual evidence on how auditors reflect managerial characteristics in the audit process by documenting that auditors actively increase their audit efforts only when overconfident managerial characteristics are highly likely to lead to audit risk. This result suggests that auditors conduct external auditing considering both the efficiency and effectiveness of the audit process. Second, we suggest that auditors use information obtained from a wide range of sources to identify audit risks. Our results provide evidence of how the auditing standards, which do not provide detailed guidelines for audit risk assessment, are being applied in practice. Finally, our results also enhance the understanding of how audit fees are determined. Combined with the studies related to audit pricing, we provide the important reference for discussion between the auditor and the auditee about the audit fee that has created acute tension after the enforcement of the new External Audit Act.

본 연구는 지상파 방송(KBS, MBC, SBS)이 자사의 이익과 관련된 이슈를 어떻게 보도하고 있는지 알아보고자 했다. 이를 위해 세 건(광고총량제, 700MHz 대역 주파수 재분배, 수신료 인상)의 이슈를 선정했고, 양적 내용분석을 통해 관련 뉴스에 드러난 보도 톤, 정보원 활용, 뉴스 프레임을 분석했다. 연구 결과, 지상파 3사 모두 자사의 이익과 관련된 사안을 보도할 때 보도 톤과 정보원 그리고 프레임 활용에서 자사의 입장을 대변하는 보도태도를 드러내고 있었다. 보도 톤 분석에서는 세 건의 이슈와 관련된 뉴스의 90%가 방송사의 입장과 일치하는 보도 톤을 갖는 것으로 드러났다. 뉴스에 활용된 정보원의 유형과 입장을 분석한 결과, 정보원의 유형은 비교적 다양했으나 주로 방송사의 입장과 동일한 입장을 가진 정보원을 활용한 것으로 확인되었다. KBS만 해당하는 수신료 인상 건은 보도 톤이나 정보원의 입장에서 다른 두 사안에 비해 중립적인 보도태도가 다소 보였지만 절대적인 측면에서는 역시 자사의 입장을 대변하는 보도가 주를 이루었다. 프레임 분석결과에서는 이슈별로 프레임 활용에 차이가 있음을 확인할 수 있었다. 광고총량제 관련 뉴스에서는 책임귀인프레임이 주로 활용되었고 700MHz 대역 주파수 재분배 이슈의 뉴스에서는 지상파 방송의 공익성 강조 프레임이 가장 주요한 프레임이었다. 한편, 수신료 인상 관련 뉴스에서는 책임귀인 프레임과 지상파 방송의 공익성 강조 프레임이 비슷한 수준으로 활용된 것을 알 수 있었다.

Objectives : The purpose of this study is to report the efficacy of using oriental medical treatment withMelonis Calyxvomiting therapy for sudden sensorineural hearing loss(SSNHL).Methods : We experienced one case of SSNHL treated with oriental medical treatment(acupuncture, herbal medicine) andMelonis Calyxvomiting therapy(MCVT). MCVT is a traditional treatment, which induces vomiting by eatingMelonis Calyxpowder with water. To evaluate the results of this treatment, we measured the hearing recovery, decrease of tinnitus and vertigo. The degree of hearing improvement was evaluated by Siegel's Criteria. Decrease of tinnitus and vertigo was assessed by Visual Analogue Scale(VAS).Results : The pure tone 5 frequency average improved by 39㏈(marked recovery, from 64㏈ to 25㏈). VAS of tinnitus decreased from 10 to 1, and vertigo decreased from 4 to 0.Conclusions : This study suggests that using MCVT with oriental medical treatment is effective on SSNHL.

Objectives : The purpose of this study is to report the case of a presbycusis patient whose hearing had improved. Methods : A 81-year-old male diagnosed with presbycusis were treated with Korean medical interventions (acupuncture combined with electromagnetic stimulation and pharmacoacupuncture) and Threshold sound conditioning(TSC) for 3 months. Pure tone audiometry(PTA) was performed for the evaluation. Results : The patient's hearing was improved from moderate to mild level according to the Classification of Hearing Loss(International Organization for Standardization, 1969). The average hearing were improved from 40.5 dB to 32.7dB on the left side, 46.9dB to 34.1dB on the right side. Conclusions : We observed an improvement in a presbycusis patient's hearing and hereby suggest the possibility of Korean medical treatment and TSC's ameliorating effect on sensorineural hearing loss as well as prebyscusis.

Tetrasomy 18p is a genetic syndrome caused by an isochromosome consisting of two copies of the short arm of chromosome 18. Clinically, pediatric cases of tetrasomy 18p manifest with global developmental delay, similar to most cases of chromosomal abnormality. In addition, it causes various symptoms including abnormal muscle tone. We report a case of an infant with global developmental delay and remarkable spasticity, the typical phenotype of bilateral spastic cerebral palsy. However, she had a subtle anomaly in her face, and brain magnetic resonance imaging (MRI) findings were inconsistent with her strong upper motor neuron signs. Upon genetic testing, she was determined to have an 18p isochromosome, confirming de novo non-mosaic tetrasomy 18p. Cerebral palsy is a neurological disorder that includes developmental delay caused by a non-progressive lesion in the developing brain. During diagnostic workup in patients with cerebral palsy, genetic testing should be considered when there are minor physical anomalies or equivocal MRI findings.

In this paper, we report the experimental results of a hybrid wideband fiber amplifier. The amplifying medium is a concatenated hybrid fiber consisting of Er-doped fiber (EDF) and dispersion compensating fiber (DCF). The gain mechanisms are based on stimulated emission in the EDF and stimulated Raman scattering (SRS) in the DCF. Since we simultaneously use optical amplification by the two processes, the gain bandwidth is easily expanded over 105 nm by a two-tone pumping scheme. Using an experimental setup constructed with a hybrid structure of EDF-DCF-EDF, we analyzed the spectral behavior of amplified spontaneous emission for pumping powers. We achieved an optical gain of over 20 dB in the wavelength range from 1,500 to 1,600 nm under optimized pumping conditions to make the spectral gain shape flat.

Partial trisomy 3p results from either unbalanced translocation or $de$ $novo$ duplication. Common clinical features consist of dysmorphic facial features, congenital heart defects, psychomotor and mental retardation, abnormal muscle tone, and hypoplastic genitalia. In this paper, we report a case of partial trisomy 3p with rare clinical manifestations. A full-term, female newborn was transferred to our clinic. She had cleft lip-plate, dysgenesis of the corpus callosum, patent ductus arteriosus, pulmonary hypertension, and severe right-sided hydronephrosis, associated with ureteropelvic junction obstruction. Cytogenetic investigation revealed partial trisomy 3p; 46,XX,der(4)t(3;4)(p21.1;p16). The karyotype of her father showed a balanced translocation, t(3;4)(p21.1;p16). Therefore, the size of duplication can be an important factor.
