포름알데히드는 그 자체가 보존제로 또는 다른 보존제로부터 유리된 형태로 화장품에 일반적으로 존재한다. 포름알데히드는 낮은 농도로도 민감한 피부 반응을 일으킬 수 있으므로 화장품에서 그 사용을 규제하고 있다. 본 연구에서는 팩 및 마스크와 같은 화장품 114 품목을 시중에서 구입하여 포름알데히드의 함량을 분석하였다. 검사 품목의 36 %에서 0.3 ~ 9.7 μg/mL (ppm) 수준의 포름알데히드가 검출되었다. 포름알데히드 유리 보존제를 함유한다고 표시되어 있는 12개 제품의 포름알데히드 함량을 조사하였다. Imidazolidinyl urea를 사용한 화장품 10품목과 1,3-Dimethylol-5,5-dimethylhydantoin (DMDM hyantoin)을 사용한 화장품 2품목에서 평균 1.7 μg/mL (ppm)의 포름알데히드가 검출 되었다. 식품의약품안전청 고시 최대 허용 포름알데히드 농도 0.2 % (2,000 ppm)을 고려할 때, 이번 조사에서 분석한 화장품에서는 비교적 낮은 수준의 포름알데히드 함량을 보였다. Formaldehyde is commonly present in cosmetic products as an ingredient intended to preserve cosmetic raw materials or as a liberated product from other formaldehyde-releasing preservatives. Since even low level of formaldehyde can elicit a dermatological reactions in sensitized individuals, there has been a tendency to restrict and regulate the use of formaldehyde in cosmetic products. In this study, we determined formaldehyde content in 114 commercial cosmetic products such as packs and masks. Formaldehyde was detected at the level ranging from 0.3 to 9.7 μg/mL (ppm) in 36 % of the tested cosmetic products. We investigated formaldehyde content of twelve products specifying to contain formaldehyde-releasing preservatives on their labels. In eleven of ten imidazolidinyl urea-containing and two 1,3-Dimethylol-5,5-dimethylhydantoin (DMDM hyantoin)-containing products, average of 1.7 μg/mL (ppm) formaldehyde level was detected. The formaldehyde levels detected in our tested products are low when compared with the maximum authorised concentration 0.2 % (2000 ppm) of formaldehyde in cosmetics according to the Korean Food and Drug Administration notice.

임학선 창작춤의 표현형식에 나타난 동양미학적 특성

정보경 ( Bo-kyung Jung ) 한국무용연구학회 2016 한국무용연구 Vol.34 No.2

본 논문은 임학선의 창작춤에 나타난 표현형식을 동양미학의 관점에서 고찰함으로써 새로운 미학적 해석의 기틀을 마련하고 이를 통하여 향후 한국창작춤이 나아가야할 바람직한 방향을 제시해 보고자 하는데 목적을 두었다. 그 방편으로 임학선의 창작춤 < 인다리 >, < 민들레왕국 >, < 마음꽃 > 세 작품을 분석대상으로 삼았으며 연구의 진행에 있어 국내외 무용평론가들의 평문, 창무회 활동자료, 안무가 임학선과의 인터뷰, 공연영상과 사진분석 등을 참조하여 논의하였다. 그리고 그 결과, 임학선의 창작춤에서 공통적으로 의상(意象)ㆍ동정(動靜)ㆍ간고(簡古) 라고 하는 세 가지 동양미학적 특성을 도출해 낼 수 있었다. 춤과의 연관성에서 살펴볼 때 의상(意象)은 상징적 이미지를 통해 주제를 표현하는 것이며 동정(動靜)은 군무와 주인공간의 긴밀한 구성, 간고(簡古)는 최소표현으로 최대효과를 추구하는 방식이라는 측면에서 기존 창작춤의 표현형식과 차별화된 표현기법이라 할 수 있다. 따라서 이러한 해석의 기틀은 현시대를 살아가는 젊은 춤작가들의 새로운 춤언어 개발과 창작정신의 고양에 있어 커다란 도움이 되리라 판단된다. By exploring the expression form appearing on Hak-sun Lim``s original dances < Indari >, < Dandelion Kingdom > and < Mind Flower > from an oriental aesthetic viewpoint, this study aimed to set up a base of new aesthetic interpretation and, through which, propose a desirable direction that Korean original dance should pursue in the future. This study referred to the reviews of domestic and international dance reviewers, the activity record material of Original Dance Association, the interviews of dancer Hak-sun Lim, the analysis on his performance video and photos, etc. Through this study, three oriental aesthetic characteristics, Eisang(意象)ㆍDongjeong(動靜)ㆍGango(簡古), could be commonly extracted from Hak-sun Lim``s original dances. Considering the association with dance, they can be considered as expression forms differentiated from those of conventional original dances in the aspect that Eisang(意象) is a method to express subjects through symbolic images, Dongjeong(動靜) is a method of close composition between group dancers and main dancer and Gango(簡古) is a method to pursue the maximum effect out of minimum expression. Therefore, the basis of such interpretation is thought to be a great help for the dance authors who are living in this modern era to develop new dance languages and encourage creation spirit.

This study aims to classify the forms of creative dance during the time when the Korean creative dance began and look into the trend of the times, correctly. It will divide the developmental patterns of the creativedance formed during the 1970s into new dance style creative dance and Korean creative dance and examine them. Also, through an analysis of the forms of the early Korean creative dance classified into the two aspects, it will investigate and reveal the spirit of the times in the Korean creative dance and its true meaning. This paper has significance that, through meditating the spirit of the times in Korean creative dance and its value, it can allow young South Korean dancers who do Korean dance in this day and age to think about what spirit they should have, think about their own philosophy of dance, and hopefully, it allows them to have a chance to find a way to establish a new genre of dance art. Moreover, hopefully, it can be thefoundation on which the genealogy of dance history can be reorganized, and it is expected that more in-depth discussions will continue in the future.

연구는 서울의 강남·강서 지역에서 유통되는 과일에 대한 470종 농약의 잔류 수준을 모니터링하기 위해 수행하였다. 총 509건의 과일 시료가 2022년 1월부터 2023년 6월까지 수집되었다. 농약을 추출하기 위해 빠르고 쉽고 저렴하며 효과적이며 견고하며 안전한(QuEChERS) 방법을 사용하였다. 222종 농약은 액체 크로마토그래피-질량 분석법(LC-MS/MS)으로 그리고 248종 농약은 가스 크로마토그래피-질량 분석법(GC-MS/MS)을 사용하여 분석하였다. 분석 결과 전체 시료의 47.7%에서 한 가지 이상의 농약에 대한 잔류량이 검출되었으며 시료당 평균 잔류농약수는 2.4종이었다. 가장 빈번하게 검출된 농약은 carbendazim (11.4%), etofenprox (8.4%), fludioxonil (7.5%) 그리고 dinotefuran (6.5%)이었다. 모든 경우에 농약 잔류 수준은 한국 식품의약품안전처에서 정한 잔류허용기준(MRL) 보다 낮은 수준이었다. 품목별 위해성은 농약별로 일일섭취추정량(EDI)을 일일섭취허용량(ADI)과 비교하여 평가하였다. 사과, 감귤, 오렌지, 포도, 그리고 복숭아 시료들에서 검출된 각 농약의 평균 잔류량으로부터 계산한 %ADI 값은 0.00001-0.2611% 범위로, 이는 이들 과일 섭취에 의한 농약 노출 위험은 낮음을 나타낸다. This study was performed to monitor residual levels of 470 pesticides on fruits distributed in the Gangnam and Gangseo districts of Seoul, South Korea. A total of 509 fruit samples were collected between January, 2022 and June, 2023. Extraction was performed using a quick, easy, cheap, effective, rugged, and safe (QuEChERS) method. Sample aliquots were analyzed for 222 pesticides using liquid chromatography-tandem mass spectrometry (LC-MS/MS) and for 248 pesticides using gas chromatography-tandem mass spectrometry (GC-MS/MS). Pesticide residues were detected in 47.7% of the samples with an average of 2.3 residues per sample. The most frequently detected pesticides were carbendazim (14.7%), etofenprox (8.4%), fludioxonil (7.5%), and dinotefuran (6.5%). All detected residues were below maximum residue limits (MRLs) set by the Korea Food and Drug Administration (KFDA). To assess the risk of pesticide exposure from fruits, the estimated daily intake (EDI) of each pesticide was compared with its established acceptable daily intake (ADI) value. Hazard indices, calculated as percentages of ADI based on average residue levels of detected pesticides in apple, mandarin, orange, grape, and peach samples ranged from 0.00001% to 0.2611%, indicating a low risk due to dietary exposure to pesticides from these fruits.

Purpose: Intestinal failure (IF) is a complex clinical condition requiring a multi-disciplinary team approach. Our objective was to set up the treatment protocols and education documents for IF patients for development of intestinal rehabilitation programs in our hospital. Methods: We compared the number of inpatients, length of hospital stay, mode of nutrition and calorie supply at discharge, and the frequency of blood transfusions before and after quality improvement of multidisciplinary activities, in order to evaluate the indirect effects of new protocols and training materials and for development of the intestinal rehabilitation system. Results: We integrated eleven protocols for treatment and monitoring and seven educational materials for patients and caregivers. We compared indirect effects before and after the quality improvement activities. The number of IF patients hospitalized was reduced from 12 to 9. The mean days of hospital stay was decreased from 322 days to 73 days, the average number of monthly blood transfusions was also reduced from 1.8 to 0.3. In addition, the percentage of patients administered enteral nutrition and calories supplied was increased at discharge. Conclusion: By integrating IF protocols and education materials for IF patients, we found possible indirect effects of intestinal rehabilitation using a multidisciplinary team approach.

본 논문에서는 구개인두부전증(VeloPharyngeal Insufficiency, VPI) 환자의 음성을 효과적으로 인식하기 위해 컨볼루션 신경망 (Convolutional Neural Network, CNN), 장단기 모델(Long Short Term Memory, LSTM) 구조 신경망을 은닉 마르코프 모델(Hidden Markov Model, HMM)과 결합한 하이브리드 구조의 음성 인식 시스템을 구축하고 모델 적응 기법을 적용하여, 기존 Gaussian Mixture Model(GMM-HMM), 완전 연결형 Deep Neural Network(DNN-HMM) 기반의 음성 인식 시스템과 성능을 비교한다. 정상인 화자가 PBW452단어를 발화한 데이터를 이용하여 초기 모델을 학습하고 정상인 화자의 VPI 모의 음성을 이용하여 화자 적응의 사전 모델을 생성한 후에 VPI 환자들의 음성으로 추가 적응 학습을 진행한다. VPI환자의 화자 적응 시에 CNN-HMM 기반 모델에서는 일부층만 적응 학습하고, LSTM-HMM 기반 모델의 경우에는 드롭 아웃 규제기법을 적용하여 성능을 관찰한 결과 기존 완전 연결형 DNN-HMM 인식기보다 3.68 % 향상된 음성 인식 성능을 나타낸다. 이러한 결과는 본 논문에서 제안하는 LSTM-HMM 기반의 하이브리드 음성 인식 기법이 많은 데이터를 확보하기 어려운 VPI 환자 음성에 대해 보다 향상된 인식률의 음성 인식 시스템을 구축하는데 효과적임을 입증한다. This paper proposes speech recognition systems employing Convolutional Neural Network (CNN) and Long Short Term Memory (LSTM) structures combined with Hidden Markov Moldel (HMM) to effectively recognize the speech of VeloPharyngeal Insufficiency (VPI) patients, and compares the recognition performance of the systems to the Gaussian Mixture Model (GMM-HMM) and fully-connected Deep Neural Network (DNNHMM) based speech recognition systems. In this paper, the initial model is trained using normal speakers' speech and simulated VPI speech is used for generating a prior model for speaker adaptation. For VPI speaker adaptation, selected layers are trained in the CNN-HMM based model, and dropout regulatory technique is applied in the LSTM-HMM based model, showing 3.68 % improvement in recognition accuracy. The experimental results demonstrate that the proposed LSTM-HMM-based speech recognition system is effective for VPI speech with small-sized speech data, compared to conventional GMM-HMM and fully-connected DNN-HMM system.

A study was carried out to optimize the cleanup step using a solid-phase extraction (SPE) cartridge, SupelClean^(TM) Florisil, for multiresidue analysis of 16 pesticides in cucumber matrix. Eluting efficiencies of two solvent systems including acetone/n-hexane and ethyl acetate/n-hexane mixtures were critically evaluated by recoveries of target anaytes from the SPE Florisil column. Based on the recovery as a measure of eluting efficiency, an acetone/n-hexane (20/80,v/v) mixture provided more than 80% recovery for 15 pesticides except bifenthrin. In case of ethyl acetate/n-hexane, 14 pesticides showed recoveries higher than 75%, while those for alachior and bifenthrin were less than 30%.
