중국 가융장족(嘉絨藏族)의 산간취락 연구

장아름(A-reum Jang) 아시아강원민속학회 2013 江原民俗學 Vol.27 No.-

가융장족은 티벳족의 한 민족으로 2세기 동안 실크로드를 지배하다가 몽골의 칭기즈칸에 의해 멸망한 서하(西夏, 1032~1227) 왕조의 후예라고 전한다. 당나라 때 존재한 동녀국(東女國)으로도 알려진 가융장족들의 풍부한 고고유적, 민속자원 가운데 장족건축의 절정인 장채(藏寨)와 조루(碉樓)등 취락 구조물은 연구가치가 매우 높다. 또한 고대 중국의 유구한 취락고고(聚落考古, Settlement Archaeology) 잔존물로서 이곳에서는 구석기, 신석기 유물들이 다수 발견되었다. 지금부터 5,500년 전 석기문화를 형성한 가융장족의 선조들이 고대취락을 형성하여 약 3천 년 전부터 이곳으로 이주하여 거주했을 것으로 추정하고 있다. 이들의 석조취락은 중국의 6대 고대촌락이라는 명성을 가지고 있으며, 목조가옥과 달리 그 전통이나 형식에서 독창성을 지니고 있다. 이것은 장족문화의 범주에 들어가지만, 특별히 가융장족만의 고유한 문화전통을 유지하고 있다는 점에서 그 가치가 높다. 이들은 3천 년 전부터 이곳에서 집단취락을 형성한 것으로 고고유물을 통해서 확인되었다. 본고는 아시아의 산간민속의 하나로서 단파 가융장족의 취락구조물을 소개하고, 미인곡(美人谷)의 특징을 논하고자 하였다. It is known that Jiāróng Zàngzú, an ethnic group of Tibetan, is the descendants of Xi Xia Dynasty that ruled Silk Road for 2 centuries and ruined by Jinghis Khan of Mongolia. The structures of settlement such as Zàngzhài (藏寨) and Zhoru (碉樓) that showed the peak of architecture of Zàngzú had high value of research among abundant archaeological sites and folklore resources of Jiāróng Zàngzú, known as Dongyeoguk (東女國) that was existed in Tang Dynasty. Here, there were found Paleolithic and Neolithic relic as remains of settlement archaeology (聚落考古) in ancient China. It was assumed that the ancients of Jiāróng Zàngzú who established Neolithic culture 5,500 years ago and moved into here approximately 3,000 years ago. These stone settlements had reputation of the Sixth ancient Chinese village and the tradition and shape were unique, contrary to wooden houses. Even thought it was included in the range of Zàngzú’s culture, it was valuable with the fact that it maintained its unique cultural tradition of Jiāróng Zàngzú. It was investigated through archaeological remains that they established the group settlement in here 3,000 years ago. This study introduced the structure of settlement of Jiāróng Zàngzú in Danba as one of mountain folklore in Asia and discussed the characteristics of Miingok (美人谷).

This study examines the design characteristics of figure skating costumes by a content analysis of their design elements. The content analysis method for the study was used based on 185 photos of female figure skaters. A total of 218 coding units in 15 categories were used. In the category of color, unicolor costumes were the mainstay and represented 48.11% of the total costumes. Black costumes showed the highest rate (13.51%), followed by red (7.57%) and blue (7.03%). In the dual-color costumes, combinations of red and black and white and black, represented 4.32% of all costumes. A camisole was the most popular type of neckline (20.54%). Stand collars with neck decorations were found in 5.95% of the costumes. In addition, 98.2% of all figure skating costumes had decorations (crystal beads 21.86% were the most frequently used decoration type), 65.41% exposed all the shoulders and arms, 70.81% of the costumes did not have sleeves, 5.41% of the costumes had arm decorations, and 3.78% had wrist decorations. In the analysis of the hem of skirts, 32.40% had a curved line, 30.73% had a straight line, and 15.08% had an unrecognizable form. In general, the figure skating costumes have stand collars with neck decorations, arm and wrist decorations, and irregular skirt hems that are not found in everyday dresses. To emphasize and intensify a theatrical effect, the costumes were fabulously decorated with spangles, crystal beads, feathers, and lace; black, red, and blue were frequently used. The skirts had frills, fringe, flared lines, and beads on them to reflect the stage lights and emphasize movements.

The purpose of this study is to analyze the performance of a computational science algorithm (ground state estimation algorithm) on a quantum computer. For this study, we calculate the device-level quantum resource requirement with a fault-tolerant quantum computation model. From the quantum compiling to the device-level execution, we measure the increase of the number of gates or steps. After this study, we realize that the current fault-tolerant quantum computation model still has lots of problems which makes uncertain the quantum computational power.

장아름(Jang, Ah,Reum) 고려대학교 교육문제연구소 2018 敎育問題硏究 Vol.31 No.4

본 연구는 대학재정지원정책 실패 제도화를 야기하는 근본 원인에 대한 학계 논의가 미진하다고 판단하고, 역사적 신제도주의 관점을 적용하여 대학재정지원정책을 둘러싼 맥락을 구조ㆍ제도ㆍ행위 수준에서 분석하였다. 분석 결과, 대학재정지원정책을 둘러싼 다양한 구조적 맥락 가운데서도 정권교체는 대학재정지원정책 변화에 가장 큰 영향력을 미쳤다. 제도적 맥락에서는 정권교체에 의해 새롭게 선출된 대통령의 국정철학이 가장 큰 영향력을 미쳤으나, 대통령의 권력을 견제하는 정책결정구조가 작동하거나 교육 현안이 발생하였을 때 대통령이 의도한 바대로 대학재정지원정 책이 추진되지 못하는 경우도 있었다. 행위 수준에서는 교육부와 기재부가 기존 대학재정지원정책 경로를 유지하려는 경향이 강하였고, 국회 교육위원회나 감사원, 대학사회는 기존 대학재정지원정책 경로에 균열을 가하는 역할을 주로 수행하였다. 분석 결과를 바탕으로 본 연구는 크게 (1)고등교육 중장기 발전계획 수립, (2)국회 교육위원회와 학계 간 대학재정지원정책 관련 포럼 개최 활성화, (3)민주적 고등교육 거버넌스체제 구축, (4)고등교육재정 안정적 확보 장치 마련, (5)국가경쟁력 강화 논리로부터 일정거리 확보 차원에서 교육ㆍ연구 환경 조성, (6)학령인구 감소를 내세운 고등교육 재정 감축논리에 대한 대응책 마련을 제언하였다. This study was intended to analyze the changes in the university funding policy according to the interaction between structural, institutional, and behavioral level surrounding the policy. Based on these results, the conclusions are as follows. First, even within the structural contexts surrounding the university funding policy, the regime change had the greatest impact on the change of university funding policy. Second, the ideology among the institutional contexts surrounding the university funding policy had the greatest influence on the change of the university funding policy, but was also limited by the policy decision structure and education system. Third, in the behavioral level the MOE and the MOSF were more inclined to maintain the existing university financial support policy path, while the National Assembly s Education Committee, the Board of Audit, and University Society played a major role in cracking the existing university funding policy path. Fourth, even in the context of structural, institutional and behavioral level surrounding the university funding policy, regime change was the most powerful factor that caused the change on university funding policy.

최아름(A Reum Choi),박동일(Dong Il Park),유귀재(Guijae Yoo),김소영(Soyoung Kim),장재범(Jae Bum Jang),채희정(Hee Jeong Chae) 한국식품영양과학회 2009 한국식품영양과학회지 Vol.38 No.11

김치와 각각의 부재료들의 향기 성분을 비교하기 위하여 GC/MS로 정성 분석한 결과, 김치의 향기 성분은 sulfide 계열의 황 화합물과 유기산, 알코올류 등으로 나타났고, 김치의 냄새를 구성하는 물질들은 김치의 냄새를 각각의 부재료에서 검출된 향기 성분들로부터 유래한 것으로 확인되었다. 김치 특유의 이취를 저감시키기 위하여 김치의 부재료인 마늘, 생강, 양파 및 파를 각각 5 ㎜의 길이와 0.3 ㎜의 두께로 세절하고 100℃에서 2분간 데친 후, 정수된 물 4℃에서 12시간 동안 침지처리 하였다. 부재료 침지처리가 김치의 군덕내(moldy odor)와 신내(sour odor)에 미치는 영향을 관능검사로 평가한 결과, 세절침지처리김치에서 일반김치에 비하여 신내와 군덕내가 크게 감소한 것으로 나타났다. 또한 부재료의 침지처리가 숙성 중 김치에서 pH, 산도, 유산균수에 영향을 미치는 것으로 나타났다. The volatile flavor compounds of kimchi and its sub-ingredients were analyzed using GC/MS. The major volatile compounds of kimchi were identified as sulfide compounds, organic acids and alcohols. It was confirmed that the major volatile flavor compounds of kimchi originated from sub-ingredients such as garlic, ginger, onion and reek. To reduce the characteristic odor of kimchi, the sub-ingredients (garlic, ginger, onion and reek) were chopped into a length of 5 ㎜ and a thickness of 0.3 ㎜, blanched at 100℃ for 2 min, and then soaked in water at 4℃ for 12 hr. The effects of soaking of the sub-ingredients on sensory evaluation with regard to characteristic odor of kimchi such as sour and moldy odor were investigated. The sour and moldy odors of kimchi were significantly reduced by the soaking of sub-ingredients. Additionally the addition of soaked sub-ingredients in kimchi had influences on the change of pH, total acidity and lactic acid bacterial count of kimchi during fermentation.

최아름(A Reum Choi),박동일(Dong Il Park),손민희(Minhee Son),김소영(Soyoung Kim),장재범(Jae Beom Jang),권상철(Sang Chul Kwon),채희정(Hee Jeong Chae) 한국식품과학회 2010 한국식품과학회지 Vol.42 No.1

본 연구에서는 천연소취식물인 감잎, 솔잎, 회향을 세절 및 추출하여 김치에 첨가하여 냄새를 masking하는 농도의 조건을 설정하고, 천연물 첨가에 따라 김치의 숙성에 미치는 연향과 휘발성 향기 성분을 분석하였다. 감잎, 솔잎, 회향을 세절물과 추출물로 김치에 첨가하여 숙성 후 신내와 군덕내에 대해 관능평가한 결과, 김치에 천연소취식물을 첨가할 때 세절물보다 추출물을 첨가했을 경우에 김치냄새의 masking 효과가 높았으며, 솔잎추출물 0.3-0.6%를 첨가한 김치와 회향추출물 0.05-0.1%를 첨가한 김치가 관능적으로 효과가 높았다. 또한 솔잎추출물 및 회향추출물을 첨가한 김치는 일반김치와 비교했을 때 pH, 총산도 및 유산균수 등의 발효특성인자들에 유의적으로 영향을 미쳤다. 또한 GC/MS로 김치 및 소취식물 추출물의 향기 성분을 분석하여, 천연소취식물을 첨가한 김치와 솔잎 및 회향추출물의 향기 성분과의 연관성을 검토하였다. 결과적으로 솔잎 및 회향추출물은 김치의 발효특성에 영향을 주어 김치 특유의 냄새를 저감시킬 수 있는 것으로 확인되었다. The use of deodorizing plant products such as persimmon leaves, pine needles and fennel seeds to mask the characteristic odor of kimchi has been proposed. Therefore, in this study, the effect of deodorizing plants on kimchi fermentation and the profile of volatile flavor compounds was investigated. During sensory evaluation tests of sour and fermentation odors of kimchi, plant extract-added kimchi showed higher sensory scores than chopped plant-added kimchi. Additionally, kimchi containing pine needle extracts (0.3-0.6%) and fennel seed extracts (0.05-0.1%) showed higher sensory scores than untreated kimchi. In addition, pine needle extract and fennel seed extract had a significant influence on kimchi fermentation characteristics such as pH, total acidity and the concentration of lactic acid bacteria. The volatile flavor compounds of kimchi and deodorizing plant extracts were also analyzed using GC/MS and the correlation of volatile flavor compounds in kimchi, plant extracts and plant-added kimchi was examined. The results revealed that the sour and fermentation odors of kimchi were reduced using deodorizing plant extracts by changing the kimchi fermentation characteristics.

This study presents the estimation of crack depth by analyzing temperatures extracted from thermal images and environmental parameters such as air temperature, air humidity, illumination. The statistics of all acquired features and the correlation coefficient among thermal images and environmental parameters are presented. The concrete crack depths were predicted by four different machine learning models: Multi-Layer Perceptron (MLP), Random Forest (RF), Gradient Boosting (GB), and AdaBoost (AB). The machine learning algorithms are validated by the coefficient of determination, accuracy, and Mean Absolute Percentage Error (MAPE). The AB model had a great performance among the four models due to the non-linearity of features and weak learner aggregation with weights on misclassified data. The maximum depth 11 of the base estimator in the AB model is efficient with high performance with 97.6% of accuracy and 0.07% of MAPE. Feature importances, permutation importance, and partial dependence are analyzed in the AB model. The results show that the marginal effect of air humidity, crack depth, and crack temperature in order is higher than that of the others.
