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.

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.

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.

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.

정상 성인에서의 Theophylline의 약동학 및 대사에 관한 연구

최혜란,신상구,이광수 중앙대학교 의과대학 의과학연구소 1989 中央醫大誌 Vol.14 No.2

Theophylline kinetics and metabolism following single intravenous infusion of theophylline dose (6mg/kg) were examined in 8 young non-smoking adults. Study design stressed stringent control of several external factors known to influence theophylline metabolism. The concentrations of theophylline were analyzed over a 24-hr period in plasma. Theophylline and its major metabolites were measured over a 96-h period in urine after the given dose. A 2-compartment model was required to describe the theophylline plasma concentration time course in all 8 subjects. The results are as follows. 1. Theophylline is quickly transferred from plasma to tissue with high rates of intercompartmental clearance (mean ±S.D; 1.04 ± 0.53 L/min). Steady-state volume of distribution of theophylline showed little intersubject variability with average of 0.42 ± 0.02 L/kg. 2. The elimination half-life of theophylline varied greatly among subjects and ranged from 4.56 to 11. 11 hours, Similarly, the non-renal clearance also showed wide intersubject variation (coeffient of variation; 35%). 3. The unbound fraction of theophylline was 62.6 ± 4.1% at the plasma concentration around 10 ㎍/ml. 4. About 82% of theophylline administered was recovered until 96-hr after dose as unchanged form or major metabolites. A 17.55% of theophylline was excreted in urine as unchanged form. Molar fraction of theophylline metabolites 1.3-dimethyl uric acid, 3-methylxanthine and 1-methyl uric acid excreted in urine were 35.14%, 11.62% and 17.64%, respectively. From the above results, It is suggested that great variation of theophylline elimination half-life seems to be mainly due to wide intersubject variation of non-renal clearance of theophylline. Importance of including an assessment of plasma protein binding in studies of theophylline disposition would be emphasized, because theophylline metabolism showed a restrictive pattern. Incomplete recovery of theophylline from the administered dose imply the possbility of exsistence of additional minor pathways in theophylline disposition, which could not be identified in the study.

This research focused on the association between clinical symptoms of mercury poisoning and mercury concentration in urine and blood. A total of 100 manual workers and 55 office workers in a fluorescent lamp manufacturing factory were selected and history-taking and physical examination were done from September 1988 to Octorber 1989. The results were as follows : 1. The urinary mercury concentration of manual workers in average was 125.9 ㎍/l(5.0-469.0㎍/l), which showed 10 times higher than that of the office workers, and the blood mercury concentration of manual workers in average was 6.3 ㎍/l00ml(0.2 -60.2 ㎍/l00㎖), which was 6.6 times higher than that of office workers. 2. The frequency of mercury poisoning symptoms appeared was higher in manual workers than in office workers. Among the symptoms, anorexia(33.0%), shyness(15.0%), gingivitis(11.0%) and stomatitis(11.0%) showed significantly higher in manual workers than in office workers. In every item of symptoms, the manual workers showed a higher average of urinary and blood mercury concentration than that of the office workers 3. The average urinary mercury concentration of symptom-holders(shyness, loss of memory and anorexia) among manual workers was higher than that of non-symptom-holders. The average blood mercury concentration of symptom-holders(excessive sweating and blood mercury concentration than that of the office workers. anxiety, loss of weight) was higher than that of non-symptom-holders. 4. Shyness, loss of memory, loss of patience, anorexia, loss of weight, dyspepsia, excessive sweating, respectively showed increase of the number of symptom - holders according to the urinary mercury level. However, there was no increase of the number of symptom-holders according to the blood mercury level.

장갑의 적합성 향상을 위한 손부위 2차원 계측정보 DB구축에 관한 연구 : 성인 남·녀 만 18세에서 만 64세를 중심으로 focused on the ages from 18to 64 of male & female adults

최혜선,김은경 한국의류학회 2004 한국의류학회지 Vol.28 No.3,4

The aim of this study was to provide the basic 2-dimensional statistics requisite in the sizing system and design of gloves. The 64 static measurements were selected to provide information about hands. Participants in the study were 824 adults, aged between 18 and 64. Subjects were divided into four age groups: 18 to 29, 30 to 39, 40 to 49, and50 to 64, and separated according to sex. Statistical tests such as Descriptive Analysis, and Anova were conducted to analyze the data and ascertain the differences among the ages. The disparities between sex groups were compared by T-test. In addition, correlation among the 57 measurements was analyzed and the results were compared to the data from Japanese and other studies. The results indicated that all the measurements were significantly larger in the male group. There were significant differences among age groups for most hand circumferences, breadths and thickness items. As the age increased, the hand circumferences, breadths and thickness items became wider and thickrer. In addition, as the age increased, the mean measurement value of the length items decreased, so that it became shorter. Hand length was highly correlated with finger length, palm length and height. Maximum hand circumference Ⅱ was highly correlated with hand circumferences, hand breadth and weight.

韓國의 傳統的 家族制度 硏究 : 宗法制度와의 關聯을 中心으로

秦惠淑 배화여자대학 1986 培花論叢 Vol.5 No.-

I have written this treatise for the purpose of the study as to the formative processe of the traditional Korean family system and to show that in what figure it existes in family laws nowadays. It was because of the long-established convention and the guard of patriarchal family system that the full equipment of democratic modern law system which has been the most necessary of all thing, was very different from those of many advanced countries. Up to the 19th century, Korea, typical succession country of the chinese law had succeeded the chines clan rules also in the scope of family system which had attached great importance to the paternal line and ancestor worship. Therefore I'll examine several systems such as his esteemed surname mourning, clothes system and taboo of marrage between same surnames and will investigate in what figure these systems has become fixed in the traditional Korean family system. It is needless to say that this paternal family system injures individual freedom, dignity and the modern thought whose fundamental principle is equality of both sexes. We should change these premodern family laws as soon as possible because they are not democratic and are irrational. Recently the public opinion is being concertrated on the fact that we should change the family system like this and create the new one suitable for modern current. So I have written this treatise to help the fundamental principle and the character of Korean family system to be understood and also to offer historical data for work of family laws revision.
