유혜선 국립중앙박물관 1999 박물관보존과학 Vol.1 No.-

조선시대 나전칠기함(유물번호: 덕4182) 상태조사 중에 발견한 白骨의 모서리 補强材에 대한 殘存脂防酸 分折을 실시하였다. 그 결과 콜레스테롤의 함량이 높아 동물성 재료임을 확인할 수 있었고, 가스크로마토그라프 분석을 통해 그 지방산 組成이 상어가죽[鼓皮]과 유사한 패턴을 보임을 알 수 있었다. 이 분석결과에 따라 나전칠기함의 손상된 보강재를 새로운 상어가죽으로 代替 復元 하였다. Residual fatty acid of the basic material[Backgol] for reinforcement used on the edges of the lacquer ware inlaid box of Joseon Dynasty was analyzed. The result showed that it contained considerable amount of cholesterol. So it was confirmed to be animal material. Gas chromatography showed that its fatty acid composition is similar to that of sharkskin. On the basis of this analysis results, the damaged area of the object was restored by using sharkskin as a material for reinforcement.

신석기시대 주칠토기의 과학적 분석(2)

유혜선,장성윤 국립중앙박물관 2000 박물관보존과학 Vol.2 No.-

본 연구는 동남해안 및 도서지방의 신석기시대 주칠토기 23점에 대한 과학적 분석의 일환으로서 먼저 태토성분, 소성온도, 안료성분 및 안료두께를 분석한 데에 이어 태토성분에 대한 통계적인 고찰 및 경도분석을 통한 안료성분의 역할을 보강하여 재정리한 것이다. 유도결합플라즈마분광기(ICP-AES)와 엑스선형광분석기(XRF)를 사용하여 태토의 성분분석을 실시하였고, 이 분석결과에 대한 다변량해석(PCA : 주성분분석법)을 수행한 결과, 토기의 태토는 범방, 욕지도, 나머지 지역의 3개 군으로 분류되었다. 또 태토와 안료의 경도를 토기 표면으로부터 깊이별로 측정한 결과, 산화철이 다량 포함된 안료층의 경도가 태토층보다 높았고 이를 통해 산화철이 고온소성시 경도를 크게 하는 역할을 했음을 알 수 있었다. 또한 안료층의 경도가 태토층 보다 높은 것은 안료층도 소성되었음을 의미하는 것으로, 토기성형시 안료를 먼저 바른 후 토기가 구워졌음을 유추해 볼 수 있다. This study, a part of scientific analysis of the 23 Neolithic red earthenwares excavated from southeastern coast and islands. We analyzed earthenware through statistical method and hardness analysis of clay, following the analysis of clay composition, its firing temperature, pigment composition and its thickness. Clay composition was analyzed by using ICP-AES and XRF, and then Principal Component Analysis (one of multivariate methods) was used for classification. As a result, clay of the earthenware was classified into 3 groups(Bumbang, Youkjido and other sites). In addition, hardness analysis of pigment and clay based on the depth of earthenware surface showed that pigment layer containing lots of Fe₂O₃ had higher hardness than clay part, which can be interpreted that Fe₂O₃ contributes to raising hardness in case of high temperature firing. The fact that pigment hardness is higher than that of clay part implies that pigment was applied before firing.

This study is an analysis of residual fatty acid of the unidentified 26 fish bone samples which were excavated from Bupchon-ri in Wonju, Kangwon province. The purpose of this study is to identify fish kind by comparing the residual fatty acid analysis with the reference data of croaker, shark, herring and weakfish. Fatty acid was separated by gas chromatography and distribution pattern was analyzed by calculating composition of each sample. Principal component analysis(PCA), one of multivariate analysis method was used to understand fatty acid distribution data. 江原道 原州市 富論面 法泉里古境(4號境)에서 출토된 생선뼈 중 종류를 확인 할 수 없었던 생선뼈 26점에 대한 잔존지방산 분석을 실시하였다. 앞서 분류한 4종류의 생선(조기, 상어, 준치, 민어)뼈에 대한 잔존 지방산 분석 기준 데이터와 비교하여 어류종류를 확인하고자 하였다. 분석은 가스크로마토그라피(Gas chromatography)를 이용하여 지방산을 분리하였고, 각각의 含量을 계산하여 시료별 지방산 분포패턴을 확인하였다. 지방산분포 데이터의 해석을 위해서 多變數分類法 중 주성분분석법을 이용하였다.

건조제를 이용한 벽부형진열장 밀폐도 간접측정

유혜선,김명남,이승은 국립중앙박물관 2001 박물관보존과학 Vol.3 No.-

박물관 진열장의 기밀성은 일반적으로 CO₂ 추적가스를 이용한 밀폐도를 측정함으로서 조사되어 왔지만 진열장 내부에 구멍을 내야하는 점은 사용 전이나 사용 중인 진열장에 대한 밀폐도 측정에 적용하는데 문제점으로 지적되어 왔다. 이에 진열장의 형상을 변화시키지 않고, 진열장의 밀폐도를 간접측정함으로서 사용 전이나 필요에 따라서는 전시중인 진열장에 대한 밀폐도를 측정할 수 있는 대안을 제시하고자 하였다. 밀폐도 간접측정법은 진열장 내부의 온습도 변화와 습도조절제(Art-sorb)의 중량변화를 통해 진열장의 기밀도를 간접적으로 알아보는 방법이다. 실험은 동일장소에 시공된 3개의 벽부형진열장을 대상으로 진열장내 조명을 켜지 않고 Art-sorb와 온습도 수집기를 넣고 12일간 진행하였다. 각 진열장내 온도와 습도 변동분을 주변변동분으로 나눠 변동율로 나타냈으며, 그 결과 온도 변동율에서는 벽부장A(0.67)가 벽부장B(0.69)나 벽부장C(0.79)보다 변동율이 적었으며 습도 변동율에서도 벽부장A(0.12)가 벽부장B(0.19)나 벽부장C(0.72)보다 변동율이 적어 기밀도가 가장 양호함을 알 수 있었다. 또한 CO₂추적가스를 이용한 직접 밀폐도 측정에서의 공기교환율에 대하여 간접 밀폐도 측정에서의 습도변동율을 대입해 보았다. The airtightness of museum cases in museums was measured by using CO₂ tracing gas, but it has been pointed that it has a problem with measuring the airtightness of a museum case which has a hole inside before it is used or while is being used. So studies tried to come up with alternatives which make it possible to measure the airtightness of a museum case before it is used or while it is being used if necessary by indirectly measuring the airtightness of the museum case without changing its form. Indirect measuring is done by measuring the change of Art-sorb weight and the change of temperature and humidity inside the museum case. Experiments were made for 12 days with three builtin wall case installed at the same place without turning on the lights but with Art sorb and the data logger of temperature and humidity put into museum case. The change rate was produced with the change of temperature and humidity inside the museum case divided by that of those around museum case. As a result, the temperature change rate of museum case A(0.67) was lower than that of museum case B(0.69) or museum case C(0.79). The humidity change rate of museum case A(0.12) was lower than that of museum case B(0.19) or museum case C(0.72) showing that its airtightness was the best. Also in the direct airtightness measurement by CO₂ tracing gas, the air exchange rate was compared with the humidity change rate by Art-sorb in the indirect measurement.

최혜선,강여선 한국의류학회 1991 한국의류학회지 Vol.15 No.3

The object of this study is to develope an improved version of brassiere with better fit and improved performance by conducting a try-on test on 6 types of revised brassieres (constructed on above basis). The study procedures consisted of a try-on test of experimentally constructed brassieres and a sensory test on fit. The results of experimentally constructed brassiere trial are as follows. 1. The sizes showing performance effects due to different types of experimentally constructed brassieres were bust length, bust height, under bust curve length, vertical and horizontal bust diamenter, upper-lower bust slope angle (direct measurement, parallel standard, upper torso tilt rate), side bust slope angle and top bust slope angle. 2. Concerning the changes in lower cup interior, elastic materials and wider portions performed better in bust up effect. 3. No effects due to different shoulder strap positions were observed, but combined with lower cup interior changes the side types proved more effective than the standard types.

PPM 믹서의 유동해석

양희천 여수대학교 2001 論文集 Vol.16 No.-

Fluid mixing is ubiquitous and essential in many natural and industrial systems. Understanding the mixing processes that occur in these diverse systems is essential for predicting many aspects of practical importance. The objective of this study is to perform the numerical investigation of flow and mixing in a spatially periodic continuous mixer using a finite enement method. The fully 3-dimensional velocity field for a partitioned pipe mixer under laminar flow conditions was obtained using commercially available CFD software. The simulated velocity field indicated that developing flows at the transitions between elements generated the greatest potential for mixing.

陸英修女史論 : 社會事業理念을 中心으로 Concerning her philosophy on social work

秦惠淑 배화여자대학 1984 培花論叢 Vol.3 No.-

Nearly ten years have gone by since she was assassinated in the occasion for the 29th anniversary of the Korean liberation on the 15th of August, 1974. Since then some writings on her achievements have been published, and her works have been observed, evaluated and praised from many perspects. It is not only because she showed her simple and noble personality and good examples for the Korean women's virtue, but she paved new paths for the Korean women to walk in bychallenging social problems of such as political, economic, cultural and educational difficulties. And she is also spoken highly of especially for having promoted the modernization of Korea and at the same time for having offered the bases for elevating higher the Korean women's positions socially and politically. It is found very difficult to introduce her lives in some paragraphs here now, but it's possible to sum them up as followings. Firstly, she passed for the national 'mirror' reflecting the light of hope to the Korean people. We have had lots of women leaders and pioneers whose contributions to the enlightening of this society, but no women offered light brighter than she in our history. Then it is not too much to say that there is no finding such a great woman as her in our history. She was a mirror reflecting charity and love to her people. Her love and charity changed the sorrow of people to happiness, darkness to light and disappointment to hope. If we say she was the real mother of the Korean people, it is logically and practically right. secondly, subjectivity and national identity she had toward this nation was firmer than any other one; this shows that she was the symbol of the real Korean whose way of life and thinking was truly Korean. Her noble character and personality were the mirror reflecting the Korean traditional value and beauty, which we are sure not to be forgotten forever by the Korean people. Thirdly, sacrifice and services she showed to her people have gone so far as to be called religious. She lots no chance of helping the poor and weak. She devoted all her energy to inspire the people with hope, courage and desire. Fourthly, her life at home based on the Korean traditional women's virtue was instructive. She was willing to do anything difficult silently behind; this was the way she helped president Park. These are only the small parts of her bright lives. As described above, it is impossible to introduce all her lives on the limited pages. It proved how much she was respected by the people that more than two millon people voluntarily joined her funeral process to show homage and grief to her. This essay aims to cherish her memory and show what the Korean women will do following her models and patterns.

기능적 Brassiere 개발에 관한 연구 Ⅰ : 착용실태 조사를 중심으로

최혜선,강여선 한국의류학회 1991 한국의류학회지 Vol.15 No.2

The object of this study is to perceive the discomforts of the brassiere consumers according to their age groups & weight groups. The study procedures consisted of a status quo study, a rating on fit and performance according to brassiere types. 1. The result of the status quo study are as follows. (1) The study showed that with getting age bust circumference and bust size become larger with a bigger tendency to droop. Thus older age, bigger bust circumference and size require a technically improved version of brassieres. (2) Slightly tight fit brassieres were favored over more ample ones. The hobbling areas were center front, under armpits, and shoulder strapareas in that order. 2. The results of fit rating on different brassiere types are as follows. (1) The areas affected by brassiere performance were length from side neck point to bust point (bust length), width between bust points and bust height. (2) Compared among brassiere types, the wire type proved most effective. The bigger cup size group had higher satisfactory rate and low discomfort on wearing.
