장정윤 ( Chang Jeong Youn ) 한국음악학학회 2021 음악학 Vol.29 No.1

본 논문은 근대 시기 음악유학을 경험한 여성 음악가 윤성덕(尹聖德, 1903~1968)에 대한 연구로서 지금껏 알려지지 않은 그녀의 삶을 당시의 신문기사, 잡지, 유학 기관에서의 기록, 미국 이민국 서류 등 새롭게 발굴한 1차 자료를 통해 구체화하고 음악 활동을 살펴보는 것에서 출발한다. 윤성덕의 삶과 음악 활동은 크게 세 시기로 나누어 살펴볼 수 있다. 첫 번째 시기는 평양의 기독교 가정에서 자라고 이화학당에서 교육을 받으며 음악에 대한 꿈을 키운 시기이며, 두 번째 시기는 선교사들의 전폭적인 지원을 받아 미국 유학을 경험하고 이후 이화여전의 교수로 부임하여 음악 교육시스템의 발전에 헌신한 시기이다. 그리고 세 번째 시기는 미국의 발전된 최신 음악 교육시스템을 경험하고 조선으로 도입하기 위해 이화여전 교수의 신분으로 다시 미국으로 건너간 이후이다. 윤성덕의 삶과 활동 전반에 나타난 음악에 대한 소명은 개인적인 성공과 명성을 위한 자아실현보다는 당시의 기독교와 여성 교육정책이라는 강력한 영향 아래에서 음악교육자의 모습으로 발현되었다. 또한 그녀는 김애식 이후 이화학당출신 미국음악유학생으로 김메리, 김영의같이 보다 많은 여성 음악가들이 선교사들의 네트워크와 지원을 통해 미국 유학을 경험하고 귀국하여 이화에 교육자로 투입되는 연장선의 시작점에 있다. 본 연구는 윤성덕이라는 인물의 삶과 음악 활동을 보다 구체화하고 관련 인물들을 밝힘으로써 한국 근대 초기에 활동한 여성 음악가의 갈등과 욕망을 심도 있게 살펴볼 수 있는 계기를 마련할 것이다. This paper is a fundamental study on Mary Sungduk Youn (尹聖德, 1903~1968), a female musician who studied abroad in early modern Korea, and starts to discover her life and her musical activities based on primary sources and historical records such as newspapers, magazines, copies of personal documents and the records from the universities and the archives in the U.S. Based on them, Youn’s life can be divided into 3 periods. The first period is the time when she was raised and educated under the Christian family and Ewha Haktang. And the second is the time when she went abroad to study music in the U.S., supported by several missionaries involved in Ewha College and the time she devoted herself as a professor to improve the music educational system of Ewha College after coming back from America. The last is the time after she revisited the U.S. for having experience on the latest music educational system and for introducing it to Ewha College. The vocation for music that appeared throughout Youn’s life and activities was manifest as a music educator under the strong influence of Christianity and women’s education policy rather than self-actualization for personal success and fame. And Youn was an important figure after Alice Kim (1890~1951) who was the first music educator going abroad to study in the U.S., and as a pioneer Youn was at the beginning of studying abroad of female musicians such as Mary Chesik Kim (1906~2005) and Youngyi Kim (1908~1986), supported by missionaries within their strong network. By discovering Youn’s life and musical activities with the people involved, this study will provide the opportunity to examine the conflicts and desires of female musicians who were active in the early modern Korea.

Background and Purposes: Over the past three decades, numerous studies performed in Korea have reported that job stress is a determinant risk factor for chronic diseases and work disability. Every society has its own culture and occupational climate particular to their organizations, and hence experiences different occupational stress. An occupational stress measurement tool therefore needs to be developed to estimate it objectively. The purpose of this study is to develop and standardize the Korean Occupational Stress Scale (KOSS) which is considered to be unique and specific occupational stressors in Korean employees. Subjects and Methods: Data were obtained from the National Study for Development and Standardization of Occupational Stress (NSDSOS Project: 2002-2004). A total of 12,631 employees from a nationwide sample proportional to the Korean Standard Industrial Classification and the Korean Standard Occupational Classification were administered. The KOSS was developed for 2 years (2002-2004). In the first year, we collected 255 items from the most popular job stress measurement tools such as JCQ, ERI, NIOSH and OSI, and 44 items derived from the a qualitative study (depth interview). Forty-three items of KOSS, in the second year, were retained for use in the final version of the KOSS by using Delphi and factor analysis. Items were scored using conventional 1-2-3-4 Likert scores for the response categories. Results: We developed eight subscales by using factor analysis and validation process: physical environment (3 items), job demand (8 items), insufficient job control (5 items), interpersonal conflict (4 items), job insecurity (6 items), organizational system (7 items), lack of reward (6 items), and occupational climate (4 items). Together they explained 50.0% of total variance. Internal consistency alpha scores were ranged from 0.51 to 0.82. Twenty-four items of the short form of the KOSS (KOSS-SF) were also developed to estimate job stress in the work setting. Because the levels of the subscales of occupational stress were gender dependent, gender-specific standard norms for both the 43-item full version and the 24-item short form using a quartile for the subscales of KOSS were presented. Conclusion: The results of this study suggest that KOSS might be an appropriate measurement scale to estimate occupational stress of Korean employees. Further and more detailed study needs to be conducted to improve the validity of this scale.

요추 추간판 탈출증은 추간판의 퇴행성 변화가 있는 30-40대에 흔하게 발생한다. 그러나, 추간판의 퇴행성 변화가 없는 소아(12세 이하)에서는 매우 드물며 그 임상증상 및 치료 방법 역시 성인과 차이가 있다. 저자들은 소아에서 발생한 요추 추간판 탈출증 5예를 경험하였기에 이에 대해 분석, 보고하는 바이다. Lumbar intervertebal disc herniation is common in the fourth to fifth decades because the intervertebral disc undergoes degenerative change. However juvenile lumbar intervertebal disc herniation (under 12 years old) is rare because there is no degenerative change, and the clinical symptoms and treatments are different from those of adults. Herein, our experience of five juvenile lumbar intervertebal disc herniation cases are analyzed and reported.

Na, Chang-Su,Kim, Wang-In,Jang, Ho-Sun,Youn, Dae-Hwan,Moon, Young-Min,Jeong, Sung-Ho,Cheon, Min-Woo The Korean Institute of Electrical and Electronic 2015 Transactions on Electrical and Electronic Material Vol.16 No.2

Low level laser therapy (LLLT) has facilitated an improvement in acupuncture treatment. In this study, we stimulated Shaochong (HT9), Dadun (LR1), Shaohai (HT3), and Yingu (KI10) acupoints with pulsed laser diodes 532 nm [green laser] and 658 nm [red laser] in rats with induced middle cerebral artery occlusion(MCAO). The animals were divided into 6 groups: intact control; MCAO control without LLLT; LLLT with red laser at HT9·LR1 and HT3·KI10 (RR); LLLT with green laser at HT9·LR1 and HT3·KI10 (GG); LLLT with green laser at HT9·LR1 and red laser at HT3·KI10 (GR); and LLLT with red laser at HT9·LR1 and green laser at HT3·KI10 (RG). We evaluated the immunohistochemical changes in the hippocampal CA1 region, and complete blood count changes. Compared to the MCAO control group, the RG group showed a significant decrease in Bax and cytochrome c levels in the hippocampus, and a significant increase in hemoglobin level, hematocrit, total white blood cell, neutrophil, lymphocyte, monocyte, and erythrocyte counts.

<P><B>Objective</B></P><P>The elevation of cellular retinoic acid-binding protein-I (CRABP-I) has been suggested as a candidate in the pathogenesis of paediatric moyamoya disease (MMD). However, few studies have addressed CRABP-I in adult onset MMD. The aim of this study was to examine the expression of CRABP-I in the cerebrospinal fluid (CSF) of adult onset MMD, and to evaluate its association with clinical presentation and postoperative haemodynamic change.</P><P><B>Methods</B></P><P>This study examined the CSF from 103 patients: bilateral MMD, n=58 (56.3%); unilateral MMD, n=19 (18.4%); atherosclerotic cerebrovascular disease (ACVD), n=21 (20.4%); and control group, n=5 (4.9%). The intensity of CRABP-I was confirmed by western blotting and expressed as the median (25th–75th percentile). The differences in CRABP-I expression according to disease entity (unilateral MMD vs bilateral MMD vs ACVD), initial presenting symptoms (haemorrhage vs ischaemia) and postoperative haemodynamic change (vascular reserve in single photon emission CT and basal collateral vessels in digital subtraction angiography) were analysed.</P><P><B>Results</B></P><P>CRABP-I intensities in bilateral MMD (1.45(0.86–2.52)) were significantly higher than in unilateral MMD (0.91(0.78–1.20)) (p=0.044) or ACVD (0.85(0.66–1.11)) (p=0.004). No significant differences were noted based on the initial presenting symptoms (p=0.687). CRABP-I was not associated with improvement in vascular reserve (p=0.327), but with decrease in basal collateral vessels (p=0.023) postoperatively.</P><P><B>Conclusions</B></P><P>Higher CRABP-I in the CSF can be associated with typical bilateral MMD pathogenesis in adults. Additionally, postoperative basal collateral change may be related to the degree of CRABP-I expression.</P>

연구목적 : 본 시험의 목적은 임상시험 시작전에 연구자들을 대상으로 PANSS Workshop을 통하여 PANSS, ESRS에 대한 국내에서의 표준화 작업을 구축하고 새로운 정신병 치료제인 리스페리돈의 효과와 안정성을 재확인하여 리스페리돈 사용에 대한 적정화를 이루는데 있다. 연구방법 : 1996년 4월부터 1996년 9월까지 국내 39개 대학병원 정신과에 입원중인 혹은 증상이 악화되어 입원하는 정신분열병 환자 377명을 대상으로 다시설 개방 연구를 시행하였다. 1주일간의 약물 배설기간을 가진후, 리스페리돈을 8주간 투여하였고, 기준점, 1주, 2주, 4주, 그리고 8주후에 평가되었다. 용량은 제1일에는 리스페리돈 1mg씩 1일 2회, 제2일에는 2mg씩 1일 2회, 제3∼7일에는 3mg씩 1일 2회 투여하였다. 이후 환자의 임상상태에 따라 임의로 증량할 수 있으며, 최대 일일 16mg을 초과하지 않도록 하였다. 추체외로 증상을 조절하기 위한 투약을 허용하였다. 임상증상 및 부작용의 평가는 PANSS(Positive and Negative Syndrome Scale), CGI(Clinical Global Impression) 그리고 ESRS(Extrapyramidal Symptom Rating Scale)을 사용하였다. 연구결과 : 377명중 343명(91%)이 8주간의 연구를 완결하였다. 치료 종결시점인 8주후 PANSS 총점수가 20% 이상 호전된 경우를 약물 반응군으로 정의할때, 약물반응군은 81.3%였다. 리스페리돈에 반응하는 예측인자로는 발병연령, 이전의 입원 횟수, 유병기간이 관련 있었다. 리스페리돈은 1주후부터 PANSS양성, 음성, 및 일반정신병리 점수상에 유의한 호전을 보여 효과가 빨랐다. CGI의 경우도 기준점에 비해 1주후부터 유의한 감소를 나타내었다. ESRS의 경우, 파킨슨 평가점수는 기준점과 비교해 투여 1주, 2주, 4주후 유의하게 증가되었다가 8주후 기준점과 차이가 없었다. Dystonia 평가점수는 1주후만 유의한 증가를 보였으며, dyskinesia 평가점수는 유의한 차이가 없었다. 혈압, 맥박수의 생명징후 및 일반 혈액학 검사, 생화학적 검사, 심전도 검사에서 유의한 변화는 없었다. 결 론 : 이상의 다시설 개방 임상 연구를 통해 리스페리돈은 정신분열병 환자에서 양성증상뿐만 아니라 음성증상 및 전반적인 증상에도 효과적인 것으로 사료된다. 보다 명확한 평가를 위해서는 다른 항정신병약물과의 이중맹검 연구가 필요할 것으로 생각되며, 또한 장기적 치료에 대한 평가도 함께 이루어져야 하겠다. Objective : The purpose of this study was to investigate the efficacy and safety of risperidone in the treatment of Korean schizophrenic patients. Method : This multicenter open study included 377 schizophrenic patients drawn from 39 university hospitals. After a wash-out period of 1 week, the schizophrenic patients were treated with risperidone for 8 weeks and evaluated at 5 points ; at baseline, and 1, 2, 4 and 8 weeks of treatment. The dose was increased from 2mg/day(1mg twice daily) to 6mg/day(3mg twice daily) during the first week and adjusted to a maximum of 16mg/day over the next 7 weeks according to the patient's clinical response. Medication to control extrapyramidal symptoms was permitted. The psychiatric and neurological status of the patients was assessed by PANSS, CGI, and ESRS scales. Results : 343(91%) of 377 patients completed the 8-week trial period. Clinical improvement, as defined by a 20% or more reduction in total PANSS score at end point, was shown by 81.3% of patients. The predictors of response to risperidone were associated older age, shorter duration of illness, fewer previous hospitalization. Risperidone had rapid onset of action ; a significant decrease of the total PANSS and three PANSS factor(positive, negative, general), and CGI was already noticed at the end of first week. For the ESRS, parkinsonism rating scores were significantly increased until week 4 comparing with baseline. Dystonia rating scores were significantly increased until week 1, and dyskinesia rating scores were not significantly changed during the study. Laboratory parameters including vital sign, EKG, hematological, and biochemical values showed no significant changes during the trial. Conclusions : This study suggests that risperidone is generally safe and effective against both the positive and negative symptoms in our group of patients.

A case of a female Manic Depressive Illness patient with goitrous hypothyroidism is presented. After ten and half months of lithium maintenance therapy starting during her first psychiatric admission, she was admitted again due to acute recurrent manic episode. On admission, she complained of easy fatigability and cold intolerance, and thyroid gland was palpable and enlarged in moderate degree. Thyroid function test revealed markedly increased TSH and moderately decreased thyroxine levels. TRH stimulation test showed an exaggerated response. Needle biopsy specimen revealed chronic lymphocytic and immune complex thyroiditis. However, antithyroglobulin and antimicrosomal antibodies were negative. In pretreatment thyroid evaluation on her first admission, neither goiter nor thyroid function abnormality was detectable and no signs of underlying thyroid disease or hereditary predisposition to hypothyroidism were present. Within three weeks of discontinuation of lithium, goiter was no more palpable and within five weeks, thyroid function test returned to normal range. The possibility that patients with underlying thyroiditis may be particularly susceptible to a rapid onset of lithium-induced hypothyroidism is discussed.

축소형 하이브릿드 커플러에 의한 아날로그 이상기

周昌福,尹晶煥 慶南大學校 附設 工業技術硏究所 1997 硏究論文集 Vol.14 No.2

본 논문에서는 축소형 하이브릿드 결합기를 사용한 새로운 형태의 아날로그 이상기를 제시하였다. 전송선로의 등가화 회로해석의 결과 얻게된 축소 이론에 의해 기존의 ??전송선에 의해 구성되는 하이브릿드 결합기의 회로 레이아웃 면적을 80%로 줄일수 있다. 이러한 축소형 하이브릿드 결합기를 사용한 이상기의 동작특성은 기존의 하이브릿드 결합기를 사용한 이상기와 비교할때 작은 위상제어전압의 범위에서 선형 동작범위가 보다 크게 되며 광대역의 주파수 범위에서 보다적은 위상오차특성을 보인다. In this paper, a new type analog phase shifter using the reduced-size quadrature branch-line hybrid coupler is suggested and its operating characteristics are compared to the phase shifter using the existing ?? quadrature branch-line hybrid coupler. Using the reduced-size quadrature branch-line hybrid coupler, fabrication area can be reduced by 80% compare to the phase shifter using the existing ?? quadrature branch-line hybrid coupler. This suggested phase shifter showed linear phase shifting characteristics from 0°to 195°in the control voltage range of 0[v] ∼ -5[v], and its insertion loss is a little high but phase difference error is decreased much that of the phase shifter using the ?? quadrature branch-line hybrid coupler.

김창석,황석영,서진연,정삼용 조선대학교 동력자원연구소 1995 動力資源硏究所誌 Vol.17 No.1

This paper describes the proper selection method of the power system stabilizer(PSS) parameter for stabilizing operation of a synchronous machine which connected to infinite bus by using pole assignment method. The purpose of PSS is to enhance the damping capability at small frequency oscillation (0.5∼2㎐). It can be achieved by moving the real part of critical eigenvalue (pole) on left side of s-plane. The PSS parameter was selected by using the proposed method to match with a pre-assigned pole associated with poorly damped swing mode. This method has been studied to synthesize the PSS on Yong-Gwang N/P. And the simulation results show that the selected parameter by using proposed method is effective for dynamic and transient stability of power system.

Biodegradable polycaprolactone/cuttlebone scaffold composite using salt leaching process

박종석,Youn-Mook Lim,Min-Ho Youn,Hui-Jeong Gwon,Young-Chang Nho 한국화학공학회 2012 Korean Journal of Chemical Engineering Vol.29 No.7

We prepared biodegradable polycaprolactone/cuttlebone scaffold composite by salt leaching process. In the first step, a co-continuous blend of biodegradable materials, polycaprolactone (PCL) and cuttlebone (CB), and an amount of sodium chloride salt particles were mixed using a stirrer. Next, the extraction of mineral salts using de-ionized distilled water was performed using a biodegradable PCL/CB scaffold with fully interconnected pores. Finally, the durable morphology of the scaffolds was fabricated by freeze-drying process at −53 oC for 24 hrs in a vacuum. In addition,the quadrilateral pres ranged from about 250 to 300 μm in diameter. Scanning electron microscopy (SEM) and mercury intrusion porosimeter techniques were carried out to characterize the pore morphology. By increasing the CB and sodium chloride salt particle content, the number of interconnected pores, material properties, and pore morphology were dramatically changed. The average compressive strengths (load at 50% strain) of the different porous PCL/CB scaffolds were found to decrease from 133 to about 79 (load at 50% strain, gf) with an increase in porosity. The values of the porosity increased as the sodium chloride salt volume fraction increased
