Human Cord Blood Stem Cell Therapy for Treatment of Stress Urinary Incontinence
이정노,장진범,김지영,Chester Koh,백진영,이경진 대한의학회 2010 Journal of Korean medical science Vol.25 No.6
Our objective in this study was to evaluate the safety and efficacy of transurethral cord blood stem cell injection for treatment of stress urinary incontinence in women. Between July 2005 and July 2006, 39 women underwent transurethral umbilical cord blood stem cell injection performed by one operator at a single hospital. All patients had stress urinary incontinence. The patients were evaluated 1, 3, and 12months postoperatively. No postoperative complications were observed. 28 patients (77.8%) were more than 50% satisfied according to the Patient’s Satisfaction results after 1 month, 29 patients (83%) were more than 50% satisfied according to the Patient’s Satisfaction results after 3 months, and 26 (72.2%) continuously showed more than 50% improvement after 12 months. Intrinsic sphincter deficiency and mixed stress incontinency improved in the ten patients evaluated by urodynamic study. Our results suggest that transurethral umbilical cord blood stem cell injection is an effective treatment for women with all types of stress urinary incontinence.

전국민속예술경연대회를 통해 본교방춤의 민속화 현상 연구-무형문화재 제도의 연계성과 교방춤의 맥락변화를 중심으로-
이정노 비교민속학회 2018 비교민속학 Vol.0 No.67
This study focused on The National Folk Art Contest held in the 1960’s and 70’s to elucidate the phenomenon that Gyobang Dance, which was created under the foundation of Confucian arts culture in the Joseon Dynasty, is now recognized as a local folk dance. The National Folk Art Contest is a system to discover indigenous and simple commoner arts scattered throughout each region. and while the Gyobang dance in this contest, it may had affected the dilution of the official image and the enhancement of the local folk culture. Gyobang dance was carried out by the Gwonbeon Gisaeng during the Japanese colonial period. So it was in a socially negative perception. however, The fact that Gyobang dance participated in The National Folk Art Contest was related to the intangible cultural heritage system that was related to the contest at the time. Gyobang Dance, designated as an intangible cultural heritage, participated in this contest, which improved the social awareness of Gisaeng’s dance. and the identity of local folk art strengthened while Gyobang Dance continues to participate in national folk art contests. Today, however, the term Gyobang dance is often used in folk dances with a learning background such as <Seungmoo> and <Salpuri Dance> So I discussed the background and meaning of this folklore together. 본 연구는 조선시대 유교 예악문화의 기반 속에서 배태된 교방춤이 오늘날 지방의 민속무용으로 인식되고 있는 현상을 조명하기 위해 1960, 70년대에 치러진 전국민속예술경연대회에 주목하였다. 전국민속예술경연대회는 각 지방에 산재하는 토착적이며 소박한 서민예술을 발굴하는 제도로서, 교방춤이 이 대회에 참가하는 동안 관변적 이미지가 희석되고 지방의 민속문화로서의 이미지가 강화되는데 영향을 미쳤을 것이라고 보았다. 교방춤은 일제강점기 권번 기생들에 의해 연행되어 오면서 사회적으로 부정적인 시선 속에 있었는데, 그럼에도 국가적 체제 하에 운용되던 전국민속예술경연대회에 참가할 수 있었던 배경은 당시 이 대회와 연계성을 지니던 무형문화재 제도와 연관이 있다고 본다. 무형문화재 지정과 관련된 교방춤이 이 대회에 참여하면서 기생의 춤에 대한 사회적 인식을 호전시켰고, 교방춤이 전국민속예술경연대회에 지속적으로 참여하는 동안 지방 민속예술로서의 정체성이 강화되었다고 보고 있다. 하지만 오늘날에는 교방춤이라는 용어가 <승무>, <살풀이춤>과 같은 권번의 학습배경을 갖는 민속춤에도 빈번히 사용되고 있어, 이러한 민속화의 배경과 의미에 대해서도 아울러 논해보았다.

Problems and Improvement of Mold Manufacturing Process of W Company
이정노,이동형 한국산업경영시스템학회 2017 한국산업경영시스템학회 학술대회 Vol.2017 No.추계초록
The purpose of this research isto make improve productivity through process improvement without expensive capital investment in a small scale mold manufacturer. The target company which is selling sand mold casting products employs many foreigners, and 50% of factory workers worked by the periphery of a specific manufacturing sector were difficult to communicate smoothly on site. Also, the company has the customized production method which production and delivery time are constant each month. However, the company's situation is getting harder since the order volume of existing suppliers has decreased and profit has reduced. So, we decided that the company needs new customers and overseas markets in the long run but to improve the process without facility investment in the short term is important task. We improved the process, created the standard of work for foreign workers, and improved the working environment by eliminating the on-site risk factors that the staff could not perceive. The results were as follows. The productivity has improved by 1.5 times. Training by work standards has shortened the OJT time of new workers and efficient working methods have become standard. Improvement of the work environment has improved the job satisfaction of workers and enabled long-term service of workers in the mold industry where labor shortage is serious.

개천예술제를 통해 본 1950∼60년대 신무용의 전개 양상 연구
이정노,이주희 한국동양예술학회 2018 동양예술 Vol.38 No.-
본 연구의 발단은 오늘날 신무용의 형태는 일제강점기 이래로 현재까지 여러 변화의 과정을 거쳐 온 것임에 주안하고, 변화의 모색이 본격적으로 진행되는 시기로 보이는 1950∼60년대에 주목하면서 시작되었다. 그러나 신무용을 ‘무대화된 한국춤’이라고 정의한다면 이 신무용은 최승희와 조택원과 같은 무용계 예술가들 뿐 아니라 한성준과 같은 전통예인들에 의해서도 연행되었음을 알 수 있다. 즉 신무용은 일제강점기부터 해방 후로도 얼마간 전통예인들에 의해서도 지속되었는데, 대표적으로 한성준의 제자이자 손녀인 한영숙과 그와 함께 활동했던 몇몇 전통예인들의 모습에서 찾을 수 있다. 전통예술가들은 무형문화재 제도가 시행되면서 국악분야의 문화재로 지정되는 1960년대부터 서서히 춤 활동이 미약해지는 모습을 보인다. 따라서 1960년대까지는 전통예술인들이 신무용을 연행했다고 할 수 있는데, 본고에서 연구 대상을 개천예술제로 설정하면서 무용계와 전통예술가들의 동시대 신무용 양상을 확인할 수 있게 되었다고 본다. 본 연구에서는 개천예술제에서 연행된 두 분야의 활동양상을 살피면서 1950, 60년대에 전개된 신무용의 한 단면을 조명해보고자 한다.

Overproduction and accumulation of melanin in the skin can lead to pigmentation disorders, such as freckles and melasma. Many researchers are studying the regulation of melanogenesis in the skin with the aim of developing whitening cosmetics. In this study, bioactivityguided separation of the hexane fraction of Schisandra chinensis (Turcz.) Baillon extract yielded five major compounds, b-chamigrenal, a-ylangenol, gomisin N, gomisin A, and schisandrin. The structures were identified by using 1H-NMR and 13C-NMR spectroscopy and comparing the spectral data with published data. Melanogenesis inhibitory activity assay in alpha-melanocyte-stimulating hormone (a-MSH)-induced B16F10 mouse melanoma cells revealed that gomisin N was the active component and significantly inhibited melanin synthesis in a concentration- dependent manner. Thus, we evaluated the mechanism underlying its anti-melanogenic effect. Gomisin N inhibited the expression of tyrosinase and microphthalmia-associated transcription factor (MITF) in B16F10 cells, while it did not affect cAMP response element binding protein (CREB) phosphorylation. Additionally, gomisin N activated AKT phosphorylation, which inhibits MITF expression. Thus, our results strongly suggest that the active compound, gomisin N, has potential for use in cosmetics to reduce hyperpigmentation.
