  • Background and Objectives: The United Kingdom (UK) national standard for the closure rate for myringoplasty is 89.5% (90.6% and 84.2% for primary and revision surgeries, respectively). The average hearing gains for primary and revision myringoplasty are 9.14 dB and 7.86 dB, respectively. This study compared the myringoplasty outcomes for a single surgeon over 5 years. Subjects and Methods: Data for 68 cases were analyzed retrospectively. The outcome measures were achievement of the tympanic membrane closure and the average hearing gain or loss. Results: The overall and primary closure rates were 97% and 98%, respectively and significantly higher than the UK national standard (p=0.0210 and p=0.0287, respectively). The revision closure rate was 93%; however, it was not significantly higher than the national standard (p=0.1872). The average hearing gain was 5.18 dB. The gains for primary and revision surgeries were 5.15 dB and 5.25 dB, respectively. Conclusions: We propose that these outcomes are a result of our surgical technique, including the simultaneous use of cortical mastoidectomy in ears with discharge.

  • This study proposed a method to analyze the economic benefit of the national map revision program using the replacement cost method. The replacement cost method measures the benefit of a project as the minimum cost to replace functions of the project with those of alternative goods or services in an existing market. Thus, the demands on 1/5,000 topographic map revision in 18 administrative tasks such as city and district management planning were surveyed in three local autonomous entities. Then the cost to alternatively fulfill the demands was estimated with the standard construction estimating system for the field surveying and surveying results in commercial GIS companies for the site investigation. With this cost estimation model, the benefit of the current national map revision program to the local autonomous entities was estimated as 265,960,999 won. And cost benefit ratios according to several revision frequencies from 0.5 to 4 year were also compared to find the optimal frequency.

  • Objective : Ventriculoperitoneal (VP) shunt complication is a major obstacle in the management of hydrocephalus. To study the differences of VP shunt complications between children and adults, we analyzed shunt revision surgery performed at our hospital during the past 10 years. Methods : Patients who had undergone shunt revision surgery from January 2001 to December 2010 were evaluated retrospectively by chart review about age distribution, etiology of hydrocephalus, and causes of revision. Patients were grouped into below and above 20 years old. Results : Among 528 cases of VP shunt surgery performed in our hospital over 10 years, 146 (27.7%) were revision surgery. Infection and obstruction were the most common causes of revision. Fifty-one patients were operated on within 1 month after original VP shunt surgery. Thirty-six of 46 infection cases were operated before 6 months after the initial VP shunt. Incidence of shunt catheter fracture was higher in younger patients compared to older. Two of 8 fractured catheters in the younger group were due to calcification and degradation of shunt catheters with fibrous adhesion to surrounding tissue. Conclusion : The complications of VP shunts were different between children and adults. The incidence of shunt catheter fracture was higher in younger patients. Degradation of shunt catheter associated with surrounding tissue calcification could be one of the reasons of the difference in facture rates.

  • Background: Primary rhinoplasty outcomes may not meet individual expectations. Consequently, reoperation may be advocated to improve results. This study examines the prevalence of individuals considering revision rhinoplasty, while identifying the main cosmetic and functional complaints and factors associated. Methodology: This is a cross-sectional study conducted in Saudi Arabia using a self-reported online questionnaire distributed through social media channels. The sample included 1370 participants who were all Saudi nationals over the age of 16 who had undergone primary rhinoplasty at least 1 year prior. Results: The prevalence of individuals considering revision rhinoplasty was 44.7%. The primary reason for considering it was the desire for further esthetic improvement in an already acceptable result (50.16%). The most common cosmetic complaints subjectively reported were poorly defined nasal tip (32.35%). The most prevalent nasal function symptom was nasal obstruction (56.9%). Significant factors associated with considering revision rhinoplasty included the physician not understanding the patient's complaints, short consultation time, low monthly income, inadequate information about the expected results, not using computer imaging to predict outcomes, lack of rapport with the surgeon, and inadequate information about the risks and complications. Conclusions: A thorough understanding of patient concerns and expectations, as well as thoughtful consideration of risk factors, may help surgeons achieve more successful outcomes and potentially reduce the incidence of revision rhinoplasties. Level of evidence: III.

  • The purpose of this paper is to make research on the contents and discussions of the draft of revised UNCITRAL Arbitration Rules that have been discussed and considered by the Working Group. At its thirty-ninth session (New York, 19 June-7 July 2006), the Commission agreed that, in respect of future work of the Working Group, priority be given to a revision of the UNCITRAL Arbitration Rules (1976). At its forty-fifth session (Vienna, 11-15 September 2006), the Working Group undertook to identify areas where a revision of the UNCITRAL Arbitration Rules might be useful. At that session, it was considered that the focus of the revision should be on updating the Rules to meet changes that had taken place over the last thirty years in arbitral practice. The largely amended provisions of the draft of revised UNCITRAL Arbitration Rules are as follows : Notice of arbitration and response to the notice of arbitration (Article 3), Designating and appointing authorities (Article 4 bis), November of arbitrators (Article 5), Appointment of arbitrations (Article 6), Appointment of arbitrators in multi-party arbitration (Article 7 bis), Challenge of arbitrators (Article 9), Replacement of an arbitrator (Article 13), Pleas as to the jurisdiction of the arbitral tribunal (Article 21), Interim measures (Article 26), Form and effect of the award (Article 32), and Liability of arbitrators (Proposed additional provisions). There are some differences between the draft of revised UNCITRAL Arbitration Rules and the KCAB Arbitration Rules. In order to jnternationalize the Korea's commercial arbitration system, it is desirable that the main articles of the draft of revised UNCITRAL Arbitration Rules should be admitted to the KCAB Arbitration Rules. In conclusion, the Commission was generally of the view of any revision of the UNCITRAL Arbitration Rules should not alter the structure of the text, its spirit, its drafting style, and should respect the flexibility of the text rather than make it more complex. The Working Group agreed that harmonizing the provisions of the UNCITRAL Model Law should not be automatic but rather considered only where appropriate.

  • The purpose of this study is to investigate the revision of the western-styled court costume in the Daehan Empire. For this purpose, 1) historical documents were reviewed, 2) one set of the court costume of Chigimgwan and another set of the court costume of Juimgwan were probed, 3) the photos of people wearing court costume were analyzed. The results of this study are as follows. First, the $14^{th}$ Imperial order of "official costume statute" had been revised in 1904, 1905 and 1907 through official gazettes. The last version of official costume statute enacted the more detail than the first rule. Second, the $15^{th}$ Imperial order of "official costume rules" had been revised in 1904, 1905, and transformed into official costume rules reform on $12^{th}$ Dec., 1906. The revision in 1905 made gold embroidery of court costume more simple than the first rule. The form of court costume was totally revised by change of the shape of adjusting on the top in the revised rule of 1906. Third, the revision in 1905 was actually manufactured and worn by the people because it can be confirmed in the relics of the court costume of $2^{nd}$ Chigimgwan in Yonsei University Museum, and the court costume of juimgwan in Kwangju Municipal Folk Museum. The relics made by the revision in 1906 had not been reported until now, but they can be confirmed in the photos left. Fourth, the sovereignity of the Daehan Empire was actually lost by $22^{th}$ Imperial family order which urged the servant having the title of nobility of Japan to wear the court costume of Japan. Therefore, the endeavor of the Daehan Empire which wanted to establish and develop the costume system of modern independent nation was discontinued.

  • Purpose: The purpose of this study is to establish guidelines for ankle-brachial index (ABI), toe-brachial index (TBI) and toe pressure with regard to healing of diabetic foot amputation wound. Material and Methods: We designed a retrospective study that included patients with diabetic foot ulcer. From 2008 to 2011, 46 patients who had suffered from amputation of a foot due to diabetic foot ulcer were included in this study. We divided them into amputation-success group and amputation-revision group, and compared their ankle-brachial index (ABI), toe-brachial index (TBI) and toe pressure between two groups. Amputation-revision group is that first forefoot amputation is failed to heal successfully and need to have another proximal amputation. Results: Toe pressure was 78 mmHg (54~107) in the amputation success group, 0 mmHg (0~43) in the amputation revision group (p=0.000). Ankle-brachial index was 1.1650(1.0475~1.1975) in the amputation success group, 0.92(0.5275~1.0750) in the amputation revision group (p=0.05), and toe-brachial index was 0.6100(0.4050~0.7575) in the amputation success group, 0.00(0.00~0.4150) in the amputation revision group (p=0.04), respectively. Conclusion: ABI, TBI, toe pressure of amputation success group were significantly higher than those of amputation revision group.
