Cis-Dichlorodiammineplatinum(Ⅱ)와 방사선조사가 흰쥐위에 미치는 영향에 관한 실험적 연구

이경자 梨花女子大學校 醫科大學 醫科學硏究所 1991 EMJ (Ewha medical journal) Vol.14 No.2

Chemotherapeutic agents may alter the radiation response in the gastrointestinal epithelium by enhancing cell killing. Cis-dichlorodiammineplatinum(Ⅱ)(Cis-DDP) has been known to interact with radiation, resulting in an apparent potentiation of radiation damage. This experiment was designed to evaluate the enhancing potential of Cis-DDP for radiation effect in rat stomach. Cis-DDP. 2.5㎎/㎏ alone did not show significant changes in rat stomach. A single fraction of 6 and 8 Gy of radiation produced the slight submucosal edema only and 10 Gy of radiation produced the epithelial proliferation with atypical gland formation. There was no significant difference in findings of gastric mucosa according to the timing of Cis-DDP 2.5㎎/㎏ administration before or after the radiation.

이경자 梨花女子大學校 醫科大學 醫科學硏究所 1991 EMJ (Ewha medical journal) Vol.14 No.4

The response of the rat bladder to single dose of Cis-dichlorodiammineplatinum(Ⅱ)(Cis-DDP). radiation(6-10 Gy). or combination of radiation and Cis-DDP was assessed from the histopathologic changes. For the combined treatment, a single dose of Cis-DDP(2.5㎎/㎏) was given 30 min before or immediately after radiation. Cis-DDP alone, show inflammatory cells infiltrations in the submucosa, soft tissue and muscle layer of the bladder. A single fraction of 6 Gy of X-ray irradiation produced congestion and edema in the submucosa and its degree was increased by increasing radiation dose. The vacuolization in the mucosa and degeneration and edema in the muscle layer was developed after 8 Gy X-ray irradiation. In combination of Cis-DDP and radiation, the edema and congestion of the mucosa and degeneration and edema of muscle layer were developed in 6 Gy X-ray irradiation group and its degree was more than radiation alone group. There was no significant difference in the change of the bladder according to the timing of Cis-DDP administration before or after the radiation. In combined group of Cis-DDP and radiation, enhancement ratio was 1.33 in normal bladder as the endpoint was the degeneration of the muscle layer.

朝鮮朝 中後期 宮中服飾 硏究 : 歷代 服飾造進記錄을 中心으로

李京子 이화여자대학교 한국문화연구원 1978 韓國文化硏究院 論叢 Vol.32 No.-

A lot of historical records on court dress in YI-Dynasty have been handed down to us. Some of the most reliable ones are Jung-Rye, Ui-Gwe, bal-Gi etc. Jung-Rye is a regulation of making court dresses. Ui-Gwe is a report on making court dresses for royal weddings and the like. Bal-Gi is a detailed record of the making process of court dresses. This study intends to compare and analyze the three literatures, thus making it possible to grasp the actualities of court dresses. The resultant findings are as follows: (1) Court dresses are composed of Chinese-style coats worn on the outside, and Korean-style jackets and slacks worn inside the coat. Gon-Ryong-Po is a Chinese-style outside dress, on the inside of which Ga-Mun-Ja, Chup-Ri and Ri-Ui are usually worn. In addition to them, Korean -style, the jackets and slacks are worn inside them. At the end of Yi-Dynasty, Chinese-style coats began to disappear, and Korean style jackets and slacks as inside manner of dressing. Records on undergarments are kept only in Jung-Rye, Ui-Gwe, and Bal-Gi. (2) One of the most generally worn dresses in the court was Chup-Ri. It was worn: a) as an undergarment for a coat suit, b) as an outer garment for everyday wear, and c) as a military uniform. When a Chup-Ri was worn as an outer garment, the undergarment was Aek-Joo Um. The others not specified here are the same as the case of Gon-Ryong-Po. Chup-Ri is a one-piece style robe, in which the jacket and skirt are attached as one. Only six of this kind of garment remain today. It shows a tendency that as time passed, the skirt became shorter, and narrow sleeves became wider. (3) Ga-Mun-Ja and Aek-Joo-Um are shown only in Ui-Gwe. Their shapes are not obvious but their required materials are the same as Dab-ho, a sleeveless tunic. It seems that Aek-Joo-Um was a type of robe dress. (4) For court headdresses, Nyon-Kwan of Myon-Bok, and Tong-Chun-Kwan of Gang-Sa-Po, and Ik-Sum-Kwan of Gon-Ryong-Po have been known up to date, but Jung-Rye and Ui-Gwe record Ma-Doo-Myon, and unknown head dress. In addition, these records indicate that Ma-Mi-Doo-Myon was worn together with Gon-Ryong-Po or Chup-Ri. It was a rule to wear Ik-Sun-Kwasn for Gon-Ryong-po. But it is a newly clarified fact that Ma-Mi-Doo-Myon was also worn. This should be manifested from other data. Jung-Rye says that Ma-Mi-Doo-Myon was a kind of Gat made of horsehairs, but the shapes is not obvious. (5) The court dresses do not show a considerable change even over a long period of time because they had been worn and used in the strictest form, however, by the end of the dynasty they suffered a lot of changes.

Some ideals of pseudo BCI-algebras

이경자,Chul Hwan Park 한국전산응용수학회 2009 Journal of applied mathematics & informatics Vol.27 No.1

The notion of *-medial pseudo BCI-algebras is introduced, andits characterization is discussed. The concepts of associative pseudo ideals(resp. pseudo p-ideals, pseudo q-ideals and pseudo a-ideals) are introduced,and related properties are investigated. Conditions for a pseudo ideal to bea pseudo p-ideal (resp. pseudo q-ideal) are provided. A characterization ofan associative pseudo ideal is given. We finally show that every pseudo BCI-homomorphic image and preimage of an associative pseudo ideal (resp. apseudo p-ideal, a pseudo q-ideal and a pseudo a-ideal) is also an associativepseudo ideal (resp. a pseudo p-ideal, a pseudo q-ideal and a pseudo a-ideal).

正常 및 異常妊娠에 있어서의 尿中Estriol에 關한 硏究

李敬子 우석대학교 의과대학 1971 우석의대잡지 Vol.8 No.1

Urinary estriol estimation is very helpful for fetal program during pregnancy although it has not been widely used in Obstetrics. In this paper the fluctuations of maternal esteriol both in normal and abnornal pregnancies, hypertensive or toxemic state, intra-uterine fetal death or similar conditions. and of post-dated pregnancy were studeid. The data presented here are based on 52 pregnant patients examined in Ewha Woman's University Hospital, Seoul, Korea. Twenty-four hour urine was collected and analyzed by the Brown method. At the same time the vaginal smear was taken from mid-lateral portion of vaginal wall and stained by papanicolaou technique. The obtained results are as follows: 1. Urinary estriol in normal pregnancy gradually increases in the 20th week of gestation up to term, and the mean estriol level during the period of 36th week to term was 15.6㎎/24hours. No less than 4㎎/24hours was observed in or after 26th week of gestation in normal conditions. 2. Generally, in toxemia or hypertensive complication of pregnancy, the estriol excretion decreases significantly(P<0.05) with the mean value of 8.11 ㎎/24hours±S.E. 0.91 in the 37th week up to term. There appears tendency of chronic placental insufficiency or fetal distress in toxemia of pregnancy on the basis of the decreased fetal weight as well as poor Apgar scores. 3. In general, the higher the systolic blood pressure the greater decrease of the urinary estriol level. There was no significant difference between mild and severe toxemias in the urinary estriol level. It is interesting to note that once the systolic blood pressure is elevated up to 150㎜Hg, the estriol excretion decreases to the same level as that at a much higher level of systolic pressure, such as 160-200㎜Hg. 4. The levels of maternal urinary estriol in preeclampsia and eclampsia were not significantly different. No fetal loss was encountered even in preeclampsia with a markedly decreased estriol level. On the other hand, it was noted that a greater number of fetal loss was encountered in eclampsia with relatively higher estriol. 5. Vaginal cytologic smear test is a good method for the evaluation of the urinary estriol level and it is an adjunct of the fetoplacental function test. 6. In the last month of pregnancy, although there was no recognizable correlation in between the fetal weight and the urinary estriol level in toxemia of pregnancy as the fetal weight increases. 7. In toxemia of pregnancy, there was no correlation between the urinary estriol and the uric acid level. 8. Urinary estriol excretion in the intra-uterine fetal death without hypertensive complication of pregnancy showed significantly lower level, less than 2.0㎎/24hours. On the contrary, the estriol level in the intra-uterine fetal death in convulsive or eclamptic woman did not decrease to such a remarkable degree as in the intra-uterine fetal death in non-toxic state, suggesting a restriction in the fetoplacental evaluation. Vaginal cytology in the intra-uterine fetal death gives an information of the level of urinary estriol, and shows a placental insufficiency picture. 9. The so called "post-dated pregnancy" merely based on the menstrual age did not invariably show a true overmaturity, hormonally or cytologically.

중국의 대학입시 제도

이경자 안암교육학회 2005 한국교육학연구 Vol.11 No.1

중국고대 사회의 성균(成均), 상상(上庠), 벽옹(벽雍) 같은 고등교육기관에서는 육예(六藝), 육덕(六德) 및 육행(六行)을 주요 교육내용으로 가르치고 이를 토대로 시험을 보았다. 이러한 시험은 서주(西周)의 '선사(選士)'에서 기원하는데, 한대(漢代)의 찰거제(察擧制), 수대(隋代)의 과거제도로 이어져 1905년 과거제도가 폐지되기까지 다양한 형태로 존재했다. 중국의 대학입학 시험은 1950년 「학생모집규정(招生規定)」에 구체적인 대학입학시험에 관한 사항을 발표하면서 오늘날의 대학입시제도가 시행되었다. 한때 대학입시제도는 문화대혁명으로 중단되기도 했지만 1977년 다시 부활되면서 현재, '3+1', '3+2', '3+X' 등의 다양한 시험형태로 시행되고 있다. 본 연구는 중국 고대 사회부터 지금까지 시행되어온 다양한 시험제도 가운데 1949년 중화인민공화국이 성립되고 나서부터 현재까지 진행되어온 대학입시 제도를 살펴보고자 하였다. 이를 토대로 현행 중국의 대학입시제도와 관련된 전반적인 사항들을 이해할 수 있는 계기가 되리라 기대한다.
