Objective: We report a case of a 73-year-old Korean male with vertigo and nausea, both of which were brought about by head repositioning. The condition was diagnosed as benign paroxysmal positional vertigo (BPPV).Method: The patient was treated with acupuncture, electroacupuncture, cupping, transcutaneous electrical nerve stimulation (TENS), and herbal medicine (Bosimsahwacheonggan-tang [補心瀉火淸肝湯]). We conducted the vertigo symptoms scale (VSS) and the dizziness handicap inventory (DHI) to evaluate the degree of the patient’s symptoms.Results: Vertigo and nausea started to improve after the administration of Bosimsahwacheonggan-tang, but although the patient took the anti-vertigo medication and a tranquilizer after the symptoms became aggravated, no prominent improvements could be observed.Conclusion: These results suggest that traditional Korean medical treatment may be effective in treating peripheral vertigo due to BPPV.

정윤경,김수빈,양정윤,문상관,정우상,권승원,조기호,Jeong, Yun-kyeong,Kim, Su-bin,Yang, Jung-yun,Moon, Sang-kwan,Jung, Woo-sang,Kwon, Seung-won,Cho, Ki-ho 대한한방내과학회 2017 大韓韓方內科學會誌 Vol.38 No.2

We describe the cases of two patients with chronic subdural hematomas who were treated with Oreong-san. The patients' symptoms improved, as verified by brain computed tomography imaging. Oreong-san may control membrane permeability by inhibiting the aquaporin channel of the outer membrane of a hematoma. We speculate that hydrostatic modulation is a key mechanism underlying the effectiveness of Oreong-san in the treatment of subdural hematomas.

오미자박과 미강 첨가배지가 느타리버섯 자실체의 γ-aminobutyric acid(GABA) 함량에 미치는 효과

정윤경,김정한,백일선,강영주,지정현,Jeoung, Yun-Kyeoung,Kim, Jeong-Han,Baek, Il-Sun,Kang, Young Ju,Chi, Jeong-Hyun 한국버섯학회 2017 한국버섯학회지 Vol.15 No.2

느타리버섯(Pleurotus ostreatus)'흑타리'의 기본배지 조성에 농산물 부산물 유래 첨가용 배지를 추가하였을 경우 기억력 증진물질 중인 하나인 GABA(Gamma-amino butyric acid)함량을 증가시킬 수 있는 배지재료와 첨가수준을 구명한 결과는 다음과 같다. '흑타리'는 5% 녹차가루 처리에서 발이율과 수량이 현저히 떨어졌고, 다시마가루는 첨가된 전체 처리구에서 생육이 불량하였으며, 10% 녹차박과 오미자박 처리구에서는 생육이 가장 양호하였으나 녹차박 처리구보다는 오미자박 처리구에서 기능성물질 함량이 더 우수한 것으로 분석되었다. 또한, 첨가 수준에 따른 자실체의 GABA 함량은 무처리 대비 녹차가루는 2%, 녹차박은 10%, 다시마가루는 1% 정도 증가되었으나, 오미자박은 5%, 10%, 15%, 미강은 1%처리구에서 1.2~2.1배 수준까지 증가되는 양상을 보였다. 결론적으로, 느타리버섯 '흑타리'의 발이율과 생육 뿐만 아니라 GABA 함량 증가를 고려한 적합 첨가 배지로는 오미자박과 미강처리시 가장 양호했으며, 자실체 GABA 함량은 오미자박 10% 처리구에서 2.1배, 미강 1% 처리구에서 12%정도가 증가됨을 알 수 있었다. This study was carried out to establish a cultivation technique for increasing the ${\gamma}$-aminobutyric acid (GABA) content in the fruit body of mushrooms by adding processed by-products. For the oyster mushroom 'Heucktari', addition of green tea powder, sea tangle powder, and green tea dregs resulted in very poor primordia formation, fruit body growth, and increased GABA. However, addition of 10% schizandra berry dregs and 1% rice bran to the basal substrate induced 100% and 10% increases, in GABA content in the fruit bodies compared to the control treatment without by-product, respectively. In addition, fruit body growth and primordia formation were greatly increased by these treatments. Therefore, GABA content was increased when the substrate was prepared by mixing an appropriate amount of schizandra berry dregs and rice bran.

정윤경,백장선,Jeong, Yun-Kyoung,Baek, Jang-Sun 한국통계학회 2007 응용통계연구 Vol.20 No.1

유전자 발현 자료(gene expression data)는 전형적인 고차원 자료이며, 이를 분석하기 위한 여러 가지 군집 알고리즘(clustering algorithm)과 군집 결과들을 검증하는 군집타당성분석 기법(cluster validation technique)이 제안되고 있지만, 이들 군집 타당성을 분석하는 기법의 성능에 대한 비교, 평가는 매우 드물다. 본 논문에서는 저차원의 모의실험 자료와 실제 유전자 발현 자료에 대하여 군집 타당성분석 기법들의 성능을 비교하였으며, 그 결과 내적 측도에서는 Dunn 지수, Silhouette 지수 순으로 뛰어났고 외적 측도에서는 Jaccard 지수가 성능이 가장 우수한 것으로 평가되었다. Many clustering algorithms and cluster validation techniques for high-dimensional gene expression data have been suggested. The evaluations of these cluster validation techniques have, however, seldom been implemented. In this paper we compared various cluster validity indices for low-dimensional simulation data and real gene expression data, and found that Dunn's index is the most effective and robust, Silhouette index is next and Davies-Bouldin index is the bottom among the internal measures. Jaccard index is much more effective than Goodman-Kruskal index and adjusted Rand index among the external measures.

정윤경 ( Yoon-kyeong Jeong ),하은혜 ( Eun-hye Ha ) 한국놀이치료학회 2016 한국놀이치료학회지(놀이치료연구) Vol.19 No.3

본 연구에서는 복지시설 청소년의 불안이 공격성에 미치는 영향에서 자아존중감의 매개효과를 규명하였다. 연구 대상은 “2013 아동복지시설 아동 치료.재활 지원 시범사업”의 대상자로 선정되었던 중ㆍ고등학생 140명이었으며, 연구 도구는 개정판 아동 불안 척도(RCMAS), 공격성 척도(BDHI), 자아존중감 척도(SES)를 사용하였다. 자료분석방법으로는 복지시설 청소년의 불안과 공격성 총점 및 각 하위요인의 관계에서 자아존중감의 매개 효과를 입증하기 위하여 다중회귀분석을 실시하였다. 또한 매개효과를 검증을 위해 Sobel의 검정방식으로 매개효과의 통계적 유의성을 검증하였다. 연구 결과, 복지시설 청소년의 불안이 공격성 총점과 공격성의 하위요인 중 부정성, 흥분성, 적의성에 영향을 미칠 때 자아존중감의 부분매개효과가 유의하였고, 공격성의 하위요인 중 우회적 공격성에 영향을 미칠 때 자아존중감의 완전매개효과가 유의하였다. 이를 통해 상담 및 심리치료장면에서 공격성을 보이는 시설청소년에게 필요한 치료적 개입을 위해서는 불안과 자아존중감과같은 내적 변인을 다루는 것이 유용하다는 것을 확인하였다. The purpose of this study was to examine the mediating effects of self-esteem on the relationship between Anxiety and Aggression amongst adolescents in welfare institutions. The subjects comprised 140 middle and high school students selected for the “2013 psychological intervention project of child treatment and rehabilitation of child welfare institutions”. They were assessed by means of the Revised Children``s Manifest Anxiety Scale(RCMAS), the Buss-Durkee Hostility Inventory(BDHI), and the Self-Esteem Scale(SES). For the purposes of data analysis, multiple regression analysis was performed in order to verify the mediating effects of self-esteem in the relationship between anxiety and the total score of aggression for the adolescents in welfare institutions and for each of the sub factors identified. In addition, in order to verify the mediating effects, the Sobel test was used to verify the statistical significance of the mediating effects. The results revealed that the partial mediating effect of self-esteem was indeed significant when anxiety affects the total score of aggression and the sub-factors of aggression, such as negativity, irritability, and hostility. Moreover, it indicated that the perfect mediating effects of self-esteem were significant when anxiety affects the sub-factors of aggression such as indirect aggression. This study confirmed that dealing with internal variables such as anxiety and self-esteem can be a very useful means of therapeutic intervention with adolescents in facilities who exhibit aggression during counseling and psychotherapy sessions.

정윤경 ( Yoonkeong Jeong ),최상준 ( Sangjun Choi ) 한국산업보건학회 (구 한국산업위생학회) 2017 한국산업보건학회지 Vol.27 No.1

Objectives : This study was conducted to evaluate the level of exposure to volatile organic compounds (VOCs) among workers handling rust preventive oils. Methods : A total of 30 bulk samples and 54 personal air samples were collected using diffusive samplers at 22 workplaces handling rust preventive oils in Daegu and Gyongsangbuk-do Province from March to October 2013. We also investigated detailed information on the related work conditions, such as kinds of products, handling methods, local exhaustive ventilation systems, and the status of the wearing personal protective equipment. All bulk samples and air samples were analyzed using gas chromatography mass spectrometry (GC-MS) to identify components to which workers potentially were exposed. Quantitative airborne concentrations of VOCs were confirmed using gas chromatography with flame ionized detectors. Results : In terms of qualitative analyses for the 30 bulk samples, we found carcinogenic, mutagenic and reproductive toxic(CMR) substances such as butane(carcinogenic Group 1A, mutagenic Group 1B), butoxy ethanol(carcinogenic Group 2), cumene (carcinogenic Group 2), ethyl benzene(carcinogenic Group 2), methyl isobutyl ketone(carcinogenic Group 2) and toluene (reproductive toxic, Group 2). As a result of full-shift based personal air samples, eight substances such as n-hexane, n-heptane, octane, nonane, decane, toluene, ethyl benzene and xylene were detected. Among them, n-hexane and n-heptane were detected in all of 54 air samples with 13.13 ㎎/㎥ and 8.61 ㎎/㎥ of maximum concentration, respectively. The level of airborne concentration from all of samples were bellow the occupational exposure limit in Korea. Conclusions : Based on the results of this study, workers handling rust preventive oils could be exposed to CMR substances contained in rust preventive oils and n-hexane and n-heptane were found as the most frequent sources of VOC exposure.

Are There Two Different Writers in You? A Study on Contrastive Rhetoric of Korean Students in the US

정윤경 ( Yun Kyung Jeong ),최호성 ( Hoh Sung Choe ) 21세기영어영문학회 2012 영어영문학21 Vol.25 No.3

The present study explored the locations of main ideas, macro-level rhetorical patterns and directness/indirectness in L1 and L2 argumentative essays written by Korean ESL students in the United States. They were divided into two groups based on their writing proficiency ability. The results indicate that most participants used English rhetoric to construct their L1 and L2 essays. They also preferred the initial location when placing their main ideas regardless of the languages they used and the varying L2 writing proficiency levels. With regard to the macro-level rhetorical patterns, they often utilized the "Explanation-Collection" style, in which the writer`s opinion is followed by equally weighted supporting reason. For argument directness/indirectness, most participants preferred to write directly. The findings of the study confirm "reverse unidirectional transfer," meaning that the rhetoric transfer actually occurred from L2 to L1.
