Traumatic brain injury (TBI) could give rise to variable clinical manifestations based on the involved structures of our bodies. Although there are no structural abnormalities proven, the patients with mild TBI suffer from chronic dizziness and imbalance. Herein, I will discuss the visuo-vestibular interaction and neuro-tological finding in TBI, which could demonstrate the clue to the diagnosis and management in dizzy patients with TBI.

정성해,정기영,김재문,김지수 대한신경과학회 2012 Journal of Clinical Neurology Vol.8 No.3

Background Mal de debarquement (MdD) literally means “sickness of disembarkation”, and refers to the illusion of movement perceived as an after-effect of traveling on a boat, train, or airplane. The pathophysiology of MdD is currently unknown. Case Report A 20-year-old man presented with dizziness and swaying sensation for 3 days after a boat trip. Compared with the follow-up EEG without symptoms, the EEG recorded while having MdD symptoms disclosed a significantly decreased alpha-band current source density at the precentral gyrus of the left frontal lobe and increased beta-2 activity at the parahippocampal gyrus of right mesial temporal region. Conclusions Our results provide evidence of deranged cortical activity in MdD. To the best of our knowledge this is the first study to document cortical correlates of MdD using an EEG sourcelocalization method.

The purpose of this study was to evaluate the clinical efficacy of a standardized special ethanol extract from Gynostemma pentaphyllum as a management for anxiety and stress of normal population. This is a two-arm, parallelgroup, randomized, double blind clinical trial comparing Gynostemma pentaphyllum extract 200 mg bid (GP-EX, n=48) or placebo bid (n=54). The main outcome measures were the decrease in anxiety sensitivity index (ASI), the State version (S-STAI) of the Stait-Trait Anxiety Inventory (STAI) and the Trait version (T-STAT) of the STAI from baseline over a 6 weeks treatment period. In more anxious group (S-STAI50 or ASI19), the anxiety in group with GP-EX was decreased significantly than one in normal population with placebo [S-STAI50: T-STAI = from 57.7 ± 6.5 (mean ±S.D.) to 46.8 ± 11.2 in normal population with GP-EX, p=0.002 vs. from 54.1 ± 9.9 to 49.0 ± 9.6 in normal population with placebo, p>0.05; ASI19: T-STAI = from 47.2 ± 12.0 to 42.4 ± 11.1 in normal population with GP-EX, p=0.022 vs. from 48.7 ± 11.5 to 46.0 ± 10.4 in normal population with placebo, p>0.05]. The most frequently reported adverse reactions considered possibly related to treatment were mild gastrointestinal events. GP-EX is more effective than placebo and is well tolerated as a therapy for anxiety and stress of normal population.

Background and Objectives: Although several methods of repositioning maneuver have been introduced for the benign paroxysmal positional vertigo involving horizontal canal (HC-BPPV), no study has investigated the nystagmus pattern during the repositioning maneuver and its correlation with the repositioning results. Therefore, we evaluated the predictive value of the nystagmus for successful repositioning by studying the nystagmus pattern during the position of the Gufoni’s maneuver. Materials and Methods: Seventeen consecutive patients (age range=36~76 years, median age=64), with a diagnosis of HC-BPPV were recruited between July and August 2010. The Gufoni's maneuver for apogeotropic and geotropic nystagmus was performed. After 30 minutes, the treatment outcome was evaluated according to the nystagmus pattern at the individual stage of Gufoni’s maneuver. Successful treatment was defined by the resolution of positional vertigo in geotropic HC-BPPV and nystagmus shifted from apogeotropic to geotropic in apogeotropic HC-BPPV. Results: In the successfully treated patients, 4 of 6 patients had the contralesional nystagmus between 1st and 2nd position of Gufoni’s maneuver. Ipsilesional nystagmus in 1st position of Gufoni’s maneuver was observed in 1 patient with apogeotropic nystagmus. And the other 1 patient with Geotropic HC-BPPV showed no nystagmus in 2nd position after contralesional nystagmus in 1st position of Gufoni’s maneuver. Unsuccessfully treated 11 patients had a conversion of nystagmus direction in 2nd position after 1st step. Conclusion: During the 2nd position of the Gufoni’s maneuver, a nystagmus toward unaffected side predicts a successful repositioning,whereas reversed nystagmus is suggestive of poor response to repositioning.

태조 왕건 친제<SUB>親製</SUB> 원주 흥법사지 진공대사 탑비의 조성배경

정성권(丁晟權) 한국국학진흥원 2016 국학연구 Vol.0 No.31

원주 흥법사지에는 진공대사 충담의 탑비가 있다. 진공대사는 921년 태조 왕건으로부터 왕사에 임명되었으며 흥법사에서 주석하다 940년 입적하였다. 입적 직후 승탑과 탑비가 조성되었다. 탑비는 941년 건립되었고 태조 왕건이 직접 비문을 작성하였다. 태조 왕건시기 비문이 작성되거나 건립된 탑비는 모두 11개이다. 이 중 유독 흥법사지 진공대사 탑비만 태조 왕건이 친제하였다. 기존의 학설은 그 이유를 진공대사 충담이 심희의 제자였다는 점에서 찾고 있다. 즉 심희로 대표되는 신라 불교의 정통성이 고려로 계승되었다는 것을 보여주기 위해 태조 왕건이 충담비의 비문을 직접 작성했다는 것이다. 이 글은 기존의 학설 이외에 진공대사 탑비가 새로운 통일왕조 고려의 등장을 신라의 유민들에게 알리고자 건립된 기념물의 성격이 있음을 주장하였다. 이에 대한 근거로 진공대사 탑비 비문과 비슷한 시기(940)에 작성된 「개태사화엄법회소」 와 동시기에 건립된 개태사 석조삼존불입상을 분석하였다. 이와 함께 탑비가 위치한 흥법사가 강원도나 경상도쪽의 구 신라 유민들이 개경으로 나아가기 위해 반드시 거쳐야 되는 병목과 같은 교통의 요지였음을 밝혔다. The Stele of the Buddhist Saint Jingongdaesa is located in Heungbeopsa temple site in Wonju city. It was erected in 941. Kign Taejo, the First King of Goryeo Dynasty reconstructed the Zen Buddhist Heungbeopsa temple for the Buddhist Saint Jingongdaesa. It was his wish to educate the people in the way of Zen, and along whith the neighboring Geodonsa Temple in Wonju and Godalsa Temple in Yeoju Heungbeopsa temple played a signigicant role during the early part of the Goryeo Dynasty period. Jingongdaesa returned from studying in China and became the royal monk to King Taejo. It is said that when Jingongdaesa entered Nirvana in 940, King Taejo wrote the epitaph himself. The epitaph is an abstract from writings of King Taejong from the Taeng dynasty of China and carved onto the monument in the character style of Wang Huiji. The original monument was damaged, and the body of it including the stone coffin containing the ashes of Saint Jingongdaesa was moved to the National Museum in Seoul. The construction style is indicative of the ambitious spirit of the people at the beginning of the Goryeo Dynasty period. To explain that why King Taejo wrote the epitaph by himself, this article study about the stone Buddha triad image at Gaetaesa that was built in 940. The Gaetaesa stone Buddha was made in the site that the Later pakje’s King surrender to Kign Taejo. In other words, the stone Buddha triad image was built in the historical and symbolic site that Wnag Geon finally achived the unification of the Later Three Kingdoms. In the same reason King Tajon built The Stele of the Buddhist Saint Jingongdaesa in Heungbeopsa temple. Because Heungbeopsa temple is a major transportation point, It was a perfect place to propagate of new country-Goryeo Dynasty-newly built.

倭館 開市 때 제공된 日本料理 기록의 비교(1705년, 1864년)

정성일(鄭成一) 한일관계사학회 2015 한일관계사연구 Vol.52 No.-

이 글은 왜관의 일본인들이 작성한 매일기(每日記)를 바탕으로 개시(開市) 때 조선인에게 제공된 일본 요리를 분석한 것이다. ㉠ 왜관의 개시요리 기록은 1705년부터 체계적으로 정리되기 시작하여 19세기 중엽까지 그것이 이어졌다. ㉡ 조선 역관과 도중(都中)에게는 밥 이외에 국 한 가지와 반찬 세 가지 즉 1즙 3채가(初市는 2즙 5채), 그리고 그들의 종자[수행원]에게는 1즙 1채가 기본이었다. ㉢ 개시요리는 계절마다 쓰이는 재료가 달랐지만, 무처럼 철에 관계없이 연중 고르게 사용되는 재료도 있었다. ㉣ 고정 메뉴인 밥과 국 이외에, 반찬으로는 조림이 가장 많이 제공되었고 그 다음이 무침이었으며, 생선회도 가끔씩 나왔다. 왜관의 일본인들이 조선측 관계자에게 김치를 반찬으로 내놓는 일도 드물게나마 있었다. ㉤ 통신사 일행에게 제공된 향응요리에 비하면 왜관 개시요리의 종류와 내용이 간소하였지만, 개시요리는 왜관 거주 일본인의 일상적인 식생활 문화가 반영된 것이었다고 말할 수 있다. This paper clarified some facts through the analysis on the foods of Japanese style supplied for private trade[Gaeshi in K.] between Joseon and Japan, using the daily records by the trade authority of Tsushima domain, Ichidaikan in Japanese. First, the Japanese foods supplied during the time of trades was to be recorded from 1705 to the middle of 19th century at the Japan House, directed by Tsushima domain. Second, rice, soup and three kinds of side dish were supplied to Korean translators[Hundo and Byeolcha in K.] and merchants[Dojung in K.], and one soup and two kinds of side dish added for them especially in the case of the first trade in the every year. But only one soup and one side dish were supplied, in addition to rice, to their encourages each time of trade. Third, the foods supplied during the time of trades were differed by seasons. But there were some vegetables used as usual as white radish. Fourth, adding to rice and soup, the foods boiled were most common, and the next was the foods seasoned. Gimisui[Gimchi in K.] was supplied for Korean translators and merchants infrequently. Fifth, the Japanese foods supplied during the time of trades were more simple than the foods for Korean Diplomatic Envoys to Japan. But it should be emphasized that Japanese food cultures of daily life at the Japan House was reflected in the foods for the trades.
