Vocal polyp is one of the representative chronic diseases of vocal folds, and it can be cured by voice therapy and/or laryngeal microsurgery. However, the existing therapeutic methods about vocal polyp are in great demand. The purpose of this study was to evaluate the effect of vocal improvement between laryngeal microsurgery and SKMVTT<SUP>®</SUP>(Seong-Tae Kim's Multiple Voice Therapy Technique), which was designed by the author. We identified 37 patients, who were diagnosed with unilateral vocal polyp, aged from 21 to 62 years(mean age: 46 years). 21 patients were treated by the SKMVTT<SUP>®</SUP> and the other 16 patients were only treated by the laryngeal microsurgery. All patients who were treated by the SKMVTT<SUP>®</SUP>, received 12 sessions of treatment, and were evaluated before therapy and after finishing the 12th session. The patients who were treated by laryngeal microsurgery, were evaluated prior to and at least 8 weeks after surgery. The results showed that the SKMVTT<SUP>®</SUP> produced better results compared to the laryngeal microsurgery alone. The SKMVTT<SUP>®</SUP> produced better results, especially, at the initial stage of voice therapy compared with those of laryngeal microsurgery. In this study, we can suggest that SKMVTT<SUP>®</SUP> may be useful in improving the voice qualities of vocal polyp patients. However, more data should be collected and evaluated to be widely used in other clinics.

이 연구에서는 ‘ㄴ$ㄹ’ 連銷가 근대국어 시기에는 逆行的 流音化가 아닌 ‘ㄹ’ 鼻音化가 적용되어 [ㄴㄴ] 으로 실현된 것이며, ‘ㄴ$ㄹ’ 配列 制約의 解決 方法의 하나로, 중세국어 시기의 模索期를 거쳐 근대국어 시기에 완성된 음운 현상임을 살폈다. 근대국어 시기의 中央 方言 文獻에서는 ‘ㄴ$ㄹ’ 連銷가 ‘ㄴ-ㄴ’과 ‘ㄴ-ㄹ’ 유형의 용례로만 나타난다. ‘ㄴ$ㄹ’ 連銷에 逆行的 流音化가 적용되는 현대국어 시기와 달리, 근대국어 시기에서는 ‘ㄹ’ 鼻音化가 적용된 것이다. 시기별 적용단계를 나열하면, 16세기는 逆行的 流音化와 ‘ㄹ’ 鼻音化의 模索期, 17세기는 ‘ㄹ’ 鼻音化의 擴散 및 定立期이며, 18~19세기는 ‘ㄹ’ 鼻音化의 維持期이다. 그리고 ‘ㄹ’ 鼻音化는 19세기 후기 이후 시기에 逆行的 流音化로 교체되어 오늘날에 이른 것이다. 즉 근대국어 시기와 현대국어 시기를 連繫하면 ‘ㄹ’ 鼻音化의 [ㄴ$ㄴ]이 保守形이며, 逆行的 流音化의 [ㄹ$ㄹ]이 改新形이다.? This study investigated the fact that 'ㄹ’ nasalization, not liquidization, was applied to modem Korean even though the liquidization was largely applied to the linkage of ‘ㄴ+ㄹ’ in contemporary Korean. It aims to clarify that the above phenomenon was the phonological phenomenon formed in modem Korean through the groping period of Middle Korean as one of the methods to solve the restriction on the ㄹ’ arrangement. The linkage of ‘ㄴ+ㄹ’ is shown as an example of the form of ‘ㄴ-ㄴ’ and 'ㄴ-ㄹ’ in the central dialect literature of modem Korean. ‘ㄹ’ nasalization is applied to modem Korean, differently from contemporary Korean that The linkage of 'ㄴ+ㄹ’ is applied to. The application stages by period were divided as follows: the period of groping reversal liquidization and ‘ㄹ’ nasalization in the 16th century; the period of speading and establishing 'ㄹ’ nasalization in the 17th century; and one of maintaining ‘ㄹ’ nasalization, in the 18th and 19th century.

The purpose of thus study were to investigate the proper conditions of struvite formation in synthetic wastewater and then to apply these conditions to effluent of anaerobic digester of livestock wastewater The conditions of struvite formation had been studied by many researchers. But a little conditions were different among them. Especially, according to suspended solid variation in livestock wastewater was investigated by few researchers. In experiment of synthetic wastewater, the proper conditions of struvite formation were pH 105, l50rpm of mixing rate, 10 minutes of reaction time, and 20 minutes of precipitation time. At same time, the ammonia nitrogen removal rates were about 99.7%, 95.5%, and 96% of synthetic wastewater, raw wastewater, and effluent of anaerobic digester of livestock wastewater at molar ratio of 2(Mg):l(N)2(P) respectively. The larger factor of NH₄/SS constant was, the more effective the removal rate of ammonium nitrogen, SS was, but the less effective COD_(cr), and TOC was. By using XRD analysis, the most certain compound in precipitate of synthetic wastewater was struvite.

Since 2008 Admissions officer system was enforced by Ministry of Education, Science and Technology in Korea. First year, 4 universities - Seoul national university, Inha university, Konkook university, Chungang university - enforced admission officer system supported by Korea government. In 2010, 87 universities will recruit about 10% of admission list by admissions officer system. According to admissions officer system execution, volunteering is more important than any other fields of non- subject realm. The past school-volunteering continue to grew in volume by simple service, but now it takes on new aspect and stands need of service-learning approach. This paper aims to clarify relationship between Admissions officer system and school-volunteering. And we suggested several roles of volunteering fields. Key Words : Admissions Officer, non-subject realm, school-volunteering, service-learning

A 14-year-old male pomeranian was present with swollen left ear. The swelling occurred from base to apex of pinna. Otitis externa persisted for two years. Hematological and serum biochemistry values were not remarkable. The surgery treatment was the most appropriate method among indwelling drain, surgical, and steroid treatment in the aural hematoma because the dog was very sensitive to touching pinna and the size of aural hematoma. Longitudinal incision was applied after general anesthesia. Cefovecin was injected to prevent secondary infection. The outcome of surgery was good. There was no evidence of recurrence for one year.

UTM을 이용한 철근의 탄성계수 측정

김민철,김성도 경성대학교 공학기술연구소 2012 공학기술연구지 Vol.18 No.-

콘크리트 구조설계기준에서는 철근의 탄성계수를 200 GPa로 규정하고 있다. 철근은 다른 토목 재료와는 달리 동방성, 균질성 등의 성질을 지닌 재료로서 일정한 탄성계수를 나타내는 것으로 보고되어, 탄성계수를 측정하는 실험은 큰 의미를 가지지 못함을 알 수 있다. 그러나 UTM(Universal Testing Maching, 만능재료시험기)을 이용하여 탄성계수 등을 측정할 때, 기계의 성능이나 측정 오차 등으로 인해 부정확한 탄성계수를 얻는 경우를 흔히 경험할 수 있다. 본 실험에서는 D19 이형철근을 이용하여 만능재료시험기로 인장시험을 실시한 후, 측정된 용력-변형률 곡선 그래프를 이용하여 탄성계수를 추정하는 방법을 제안한다. 용력-변형률 곡선 탄성영역(그래프 원점율 0%, 항복점율 100%로 가정)에서 항복점 하중의 40%와 85% 사이에서의 곡선 기울기를 회귀 분석하여 추정한 값이 가장 안정된 탄성계수임을 알 수 있었다.

Abstract Since the Northern Sea Route (NSR) was formally open to the outer world in 1991, many countries have shown their interests on their possible use of NSR as an alternative commercial route for cargo transportation. However no regular transit flows have not been established yet exploiting the shortest distance connecting the Far East and the West Europe. This is mainly due to the lack of information needed to determine the economic advantages of using the NSR over other existing routes. This paper is to provide some fundamental economic and logistics information needed to see whether it will make sense to use NSR and to attemp to build an ice class merchant ship at this points from the Korean national point of view. Potential cargo flows are studied to find out a few promising products for transporting via NSR from the northern Russia and the neighboring countries to Korea. Besides economic efficiencies, some important aspects of relevant risks, service quality and relating issues needed for guaranteeing a stable logistics system are also discussed.

經濟成長과 經濟安定政策에 관한 小考

崔成哲 釜山 外國語 大學校 1986 外大論叢 Vol.4 No.1

This paper is concerned with the economic growth and stabilization policies, utilizing the neoclassical growth model and Harrod-Domar type post-keynesian growth model. First, the relation between the problems of economic growth and stabilization, the gap between economic theory and policies and the theoretical foundation of political setting up are considered in section Ⅱ. In section Ⅲ especially the policies maximizing the rate of economic growth in developing countries are examined in line with the implications of post-keynesian growth model, where public finance takes both roles as investor and saver. In addition to this the political implications of neoclassical gorwth theory and the limitations of growth policies are investigated. The stabilization policies for GNP fluctuation and price stabilization policies are studied in section Ⅳ, by using Musgrave model where built-in-stabilizer has utmost importance, and Keynesian economics respectively. Finally, the possibility of synthetic long-term econimic policies for simultaneous achievement of economic growth and stabilization are viewed.
