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.

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.

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.

1. Background of this study : People want to enjoy travel in pleasant environment. During travel, which can be an extension of an usual life, people want to have rights to use good facilities and enjoy pleasant surroundings. 2. Purpose of this study: Therefore, this study investigates to improve the quality of accommodation environment, which si one component of travel environment which is a provision of the first article of the environment protection law : Let people live in healthy and pleasant environment. 3. Scope and procedures of this study This study confined the study scope to trafel facilities, service, and surroundings, which is a part of manmade environment in contrast to the natural environment. This study has been divided into five chapters. 1) Chapter 1: Introduction 2) Chapter 2: Theoretical background on the accommodatio environment 3) Chapter 3: Basic conditions for the accommodation environment 4) Chapter 4: Establishment of the sound accommodation environment 5) Chapter 5: Conclusion and recommendation 4. Conclusion: This study searches for problems regarding accommodation environment in Korea, and suggests possible solutions in terms of survival and intellectual conditions to establish sound accommodation environment. The problem related to environment is due to ignorance of law and lack of appropriate policies. The strategy is to improve the quality of environment rather than the quantity enforced by law, and to supplement technical insufficiency. By understanding and controlling the accommodation environments appropriately, arrangements for accommodation facilities can be made. By utilizing the harmonic balance of accommodation environment, systemic development to manage human environments in an integrative manner should be sought.

蘇軾 詩學의 "反常合道"를 논함

安熙珍 한국중국문화학회 1998 中國學論叢 Vol.7 No.-

對於蘇軾<書柳子厚漁翁詩>一文中所謂的"反常合道", 歷來不少人認爲, 這是詩歌在表現上反常而內容却合情合理的意思. 我覺得單看字面意則無可置疑. 但是我們不可忽略蘇軾的這一句就是對柳宗元<漁翁詩>而說的. 他開宗明義說, "詩以奇趣爲宗, 反常合道爲趣. 熟味此詩有奇趣". 我認爲此詩雖有奇趣, 但沒有任何反常的表現, 而極其平淡自然. 幷且從我硏究蘇軾的主要文學理論來看, 他對詩歌的一貫主張可以歸納爲, 詩歌要平淡自然. 因此, 本論文認爲蘇軾詩學的"反常合道"意謂着, 理想的詩歌像<漁翁詩>那樣在表現上平淡自然, 而內容却呈現出微妙的詩境的意思.

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.

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.
