        클로미펜에 얇은 자궁내막을 보이는 환자에서 성선자극호르몬 병합 과배란유도시 클로미펜과 레트로졸의 임상적 효용성

        이은주,박현종,양효인,이경은,서석교,김혜연,조시현,최영식,이병석,박기현,조동제,Lee, Eun-Joo,Park, Hyun-Jong,Yang, Hyo-In,Lee, Kyung-Eun,Seo, Seok-Kyo,Kim, Hye-Yeon,Cho, Si-Hyun,Choi, Young-Sik,Lee, Byung-Seok,Park, Ki-Hyun,Cho, Dong-Ja 대한생식의학회 2009 Clinical and Experimental Reproductive Medicine Vol.36 No.2

        목 적: 클로미펜을 사용한 배란유도시 얇은 자궁내막을 보였던 환자들에서 성선자극호르몬에 클로미펜 또는 레트로졸을 병합 투여하는 과배란유도 방법의 임상적 효용성을 비교 분석하고자 하였다. 연구방법: 이전의 클로미펜을 사용한 배란유도 주기에서 8 mm 미만의 얇은 자궁내막을 보였던 불임 환자들에서 시행된 성선자극호르몬 병합 과배란유도/인공수정 51주기가 연구에 포함되었다. 월경주기 제3일째부터 5일 동안 클로미펜+성선자극호르몬 군은 일일 클로미펜 100 mg을 투여하였고 (n=26) 레트로졸+성선자극호르몬 군은 일일 레트로졸 2.5 mg 또는 5 mg을 투여하였다 (n=25). 양 군에서 월경주기 제5~7일째부터 우성난포의 크기가 18 mm 이상에 도달할 때까지 이틀에 한 번씩 성선자극호르몬은 75~150 IU를 투여하였다. 양 군에서 성선자극호르몬 총 사용량, 자궁내막의 두께, 자궁내막의 형태, hCG 투여일의 14 mm 이상 난포의 수, hCG 투여일, 임신율, 다태 임신율을 비교하였으며 통계 분석은 Mann-Whitney U test or Fisher's exact test 등을 이용하였다. 결 과: 연령, 불임기간, 이전 인공수정 횟수, 기저 혈중 LH, FSH, $E_2$ 농도, 불임의 원인 등의 임상적 특성은 양 군간 차이가 없었다. 성선자극호르몬 병합 과배란유도시 배란전 자궁내막의 두께는 이전의 클로미펜을 사용한 주기와 비교하여 유의하게 증가되었다. 성선자극호르몬 총 사용량, hCG 투여일, 자궁내막의 삼중선 비율, 임신율 및 다태 임신율은 유의한 차이가 없었다. 클로미펜+성선자극호르몬 군에 비하여 레트로졸+성선자극호르몬 군에서 14 mm 이상 난포의 개수는 유의하게 적었고 ($3.7{\pm}1.7$ vs. $2.8{\pm}1.7$, p=0.03). 배란 전 자궁내막 두께는 유의하게 두꺼웠다 ($7.7{\pm}1.5\;mm$ vs. $9.1{\pm}1.7\;mm$, p<0.05). 결 론: 배란유도를 위하여 클로미펜 사용시 얇은 자궁내막을 보였던 환자들에서 인공수정을 위한 과배란유도시클로미펜 또는 레트로졸을 성선자극호르몬과 병합하여 사용하는 방법은 클로미펜의 자궁내막에 대한 부정적인 효과를 피할 수 있는 것으로 사료된다. 적절한 자궁내막의 발달 및 적절한 난포의 성장 측면에서 성선자극호르몬에 레트로졸을 병합하는 과배란유도 방법이 클로미펜을 병합하는 방법에 비하여 더 유용할 수 있으나 추가적인 대규모 전향적 연구가 필요할 것으로 사료된다. Objective: The aim of this study was to compare the clinical efficacy of clomiphene citrate (CC) and letrozole combined with gonadotropins for controlled ovarian stimulation (COS) in patients with CC-induced thin endometrium Methods: Fifty-one intrauterine insemination cycles performed in patients who previously had a thin endometrium (<8 mm) to ovulation induction using CC were included in this study. A CC 100 mg/day (CC+gonadotropin group, n=26) or letrozole 2.5 or 5 mg/day (letrozole+gonadotropin group, n=25) was administered on day 3~7 of the menstrual cycle, combined with gonadotropins at dose 75~150 IU every other day starting on day 5~7. We compared total dose of gonadotropin used, endometrial thickness, endometrial pattern, number of follicles ${\geq}14\;mm$ on hCG day, pregnancy rate and multiple pregnancy rate between the two groups, which were statistically analyzed using Mann-Whitney U test or Fisher's exact test, where appropriate. Results: There were no significant differences in clinical characteristics such as age, duration of infertility, number of previous IUI cycles, basal serum hormone levels and cause of infertility between the two groups. In both groups, the endometrium was significantly thicker than that of previous ovulation induction cycles using CC. No significant differences were found in the total dose of gonadotropin used, day of hCG administration, the rate of triple endometrium and pregnancy rate. The number of follicles ${\geq}14\;mm$ was significantly lower ($3.7{\pm}1.7$ vs. $2.8{\pm}1.7$, p=0.03) and the endometrium on hCG day was significantly thicker ($7.7{\pm}1.5$ vs. $9.1{\pm}1.7$, p=0.001) in letrozole+gonadotropin group compared to CC+gonadotropin group. Conclusion: The clomiphene citrate and letrozole combined with gonadotropins appear to avoid the undesirable effects on the endometrium frequently seen with CC for ovulation induction. However, in terms of adequate endometrial development or optimal follicular growth, letrozole may be more beneficial than CC for gonadotropin-combined COS in patients with CC-induced thin endometrium. Further prospective randomized controlled studies in a larger scale will be necessary to confirm our findings.

        의과대학부속병원 의사들의 양.한방 협진에 대한 인식

        이은주,박한솔,이소영,배다정,이탁근,신현규,Lee, Eun-Joo,Park, Han-Sol,Lee, So-Young,Bae, Da-Jung,Lee, Tag-Gun,Shin, Hyeun-Kyoo 대한한방내과학회 2012 大韓韓方內科學會誌 Vol.33 No.3

        Objectives : This study was aimed to promote the cooperative system of Korean and Western medicine in the dual health care system through a survey of physicians on recognition, problems and solution of the cooperative system. Methods : The research took place at Dongguk University Hospital from May 25 to 27, 2009 with 44 professors, residents, and interns employed by the hospital. Results : Of total 44 surveyed doctors, positive and moderate responses on the cooperative system between Korean and Western medicines were 40.9% and 43.2%, respectively. They scored it positive (62.5%) and moderate (31.3%) based on their experiences. These results can be supposed to represent the environment for the interdisciplinary medicine. Even in the interdisciplinary hospital of Korean and Western medicine, 68.2% of responders had no experience of the cooperative medical system. Expected interdisciplinary efficient departments were ordered rehabilitation medicine, neurology and orthopedics and associated with musculoskeletal disorders, the most frequent diseases treated by Korean traditional medicine. Conclusions : Korean and Western medical doctors, as medical personnel, intellectual persons as well as specialists, need a recognition and attitude to understand and respect each others' medicine. However, both groups also realize there are many complicated issues in the treatment of patients. It is difficult to require a change of Western doctors' perceptions and attitude toward Korean traditional medicine only with results of a survey. For the efficient cooperative system in the medical field, Korean medical doctors will need to study and consider specific problems mentioned by Western medicine.

        경피적 내시경적 위루술을 이용한 병적 공기 연하증 치료 경험 1례

        이은주,송애령,최은진,황진복,오희종,이영환,Lee, Eun-Joo,Song, Ae-Ryong,Choi, Eun-Jin,Hwang, Jin-Bok,Oh, Hee-Jong,Lee, Young-Hwan 대한소아소화기영양학회 2000 Pediatric gastroenterology, hepatology & nutrition Vol.3 No.1

        저자들은 정신 지체를 가진 병적 공기 연하증환자를 임상 증상과 단순 흉부 X-선 사진상의 '식도 내 공기 징후'와 투시진단법으로 진단하여 보고하는 바이며, 본 증례와 같이 장기적으로 호전을 보이지 않는 공기 연하증 환자에서 조기에 PEG를 시행하여 공기를 빼내는 도구로 이용하면, 심각한 합병증의 발생을 예방할 수 있을 것으로 판단된다. We experienced a case of pathologic aerophagia in a 10-year-old girl who has mental retardation. It was observed that the abdomen was non-distended in the morning and became maximally distended in the evening. Increased passage of flatus, but normal eructation, was noted. Roentgenographic examination showed 'esophageal air sign', abnormal air shadow on proximal esophagus adjacent to the trachea, in simple chest X-ray and visible air swallowing fluoroscopically. We tried a percutaneous endoscopic gastrostomy (PEG) to decompress swallowed air in stomach. We suggest that placement of a PEG catheter in early life, especially in mentally retarded patients, that can be used as desufflator, can prevent the complications of aerophagia. 'Esophageal air sign' may be very helpful for early detection of pathologic aerophagia.

        조선시대 품대의 구조와 세부 명칭에 관한 연구

        이은주(Eun Joo Lee) 한국복식학회 2011 服飾 Vol.61 No.10

        The ranking belts for Joseon dynasty officials that are based on references and relics are studied in this paper in terms of architecture, detailed names, and structural changes according to different time. Officials` uniforms consist of hats, clothes, belts, and shoes. Among these, the belt is an important sign that represents the wearer`s ranking. The ranking belts of the Joseon dynasty which were brought from Ming at the late stage of the Koryo dynasty became classified as the following four classes : Seo-dai(a rhinoceros` horn, 犀帶), Gum-dai(gold, 金帶), Eun-dai(silver, 銀帶), and Heug-gag-dai(black horn, 黑角帶). A ranking belt consists of a basic belt body(程) and a plaque that represents the wearer`s rank. A plaque consists of 20 plates: three front-center plates that represent the Sam-tai(三台) constellation, six front-side plates that represent the Namduyug constellation(南斗六星), seven back plates that represent the Big Dipper(北斗七星), left side Bo(輔), right side Pil(弼), and a couple of Tamie at both ends. The architecture of the belt body; the basic frame for ranking belts, shows some differences between the former and the latter periods of the Joseon dynasty. In the former period, the belt had a pair of a buckle so that the wearers were able to adjust the belt size. But later, the belt didn`t have the buckles to adjust the belt size and consequently it only performed a locking or unlocking function. Therefore, the belts in the latter period were longer than normal and one size fit all. In addition to the functional change of buckles, the shapes of the ranking belts show changes from the round shape to the square shape as time goes on.

        The community of phytoplankton were investigated in Lake Soyang from January 1986 to August 1991. Dominant species in Lake Soyang was Melosira granulata, Asterionella spp. in winter, Peridinium spp. in spring, Anabaena spp. from summer to autumn, respectively. Spondylosium spp. dominated by early spring 1986 but did not thereafter. Lately, it is occurenced the number of dominant species were apt to be reduced. The value of Shannon-Wiener diversity index was inclined to decrease year by year in Lake Soyang and it became the lowest when Anabaena spp. domonated. When Peridinium spp. dominated, partial phenomena of water bloom was in full outbreak at some tributary regions between 1982 and 1985. Thereafter, Peridinium spp. significantly decreased except for showing the dominance only for one month in early spring each year. It is considered that blooming of anabaena spp. at the outer layer induced the reduction of growth of other phytoplankton. These prolonged dominance period of Anabaena spp. was thought to be enhanced by the allochthonous organic matter of fishfarms within the lake. If no essential counter-measure are taken, eutrophication of Lake Soyang would get worse because of oversupply of the organic matter.

        간호대학생의 우울, 피로, 신체존중감은 월경전 증상에 영향을 미치는가?

        이은주,양승경,Lee, Eun Joo,Yang, Seung Kyoung 한국여성건강간호학회 2020 여성건강간호학회지 Vol.26 No.3

        Purpose: The purpose of this study was to investigate factors affecting premenstrual symptoms among nursing students, focusing on depression, fatigue, and body esteem. Methods: The participants were 145 nursing students at a university located in Changwon, Korea. Data were collected from November 2 to November 30, 2019 using self-reported structured questionnaires, and analyzed using descriptive statistics, independent t-test, analysis of variance, Pearson correlation coefficients, and multiple regression analysis. Results: The mean item score for premenstrual symptoms was 2.52±0.92, indicating a low level. The mean score for depression was 16.05±7.72, and 15.2% of participants were found to be moderately depressed and 9.7% severely depressed. The mean item score for fatigue was 4.84±0.84, indicating a moderate level, and body esteem was 2.94±0.44, indicating a moderate level. The premenstrual symptoms of nursing students showed a statistically significant correlation with depression (r=-.58, p<.001), fatigue (r=.33, p<.001), and body esteem (r=-.28, p<.001). Factors impacting premenstrual symptoms of nursing students were depression (β=.47, p<.001), dysmenorrhea (β=-.18, p=.009), menstrual cycle irregularity (β=.17, p=.013), and body esteem (β=-.14, p=.038). The total explanatory power of these variables was 41.0%. Conclusion: Findings from this sample of nursing students suggest that intervention programs to relieve premenstrual symptoms should focus on depression, menstrual cycle irregularity, dysmenorrhea, and body esteem.

        후기 학령기 아동의 성지식 요구

        이은주,Lee Eun Joo 한국아동간호학회 2000 Child Health Nursing Research Vol.6 No.2

        The goal of this research was to provide the basic data of sexual education for late schooler by finding out what they want to know about sex, or to see, if any, its relevancy between female and male students and between each grade. The sample for this research was a total of 453 students in 4th, 5th and 6th grade from 12 different classes at two elementary schools which were located in C city and in B province. The children were requested to write down three points on what they want to know or to learn most about sex, and their answers were put through two analytical stages in order to classify and to examine. The followings are the conclusions from the data. 1. The female cluster took 44.2% out of the whole sample, and there were 151 students per each grade. The specific girl ratios for each grade were 42.4%, 50.3% and 39.7% respectively. 2. It was noted that a total of 1,195 questions were gathered from the students writings, 45% of the questions was raised by the female students. The 4th grade students raised 432questions (43.8% by the girl) while the 5th. and the 6th grade students raised 387 (53.2% by the girl) and 376 questions (42.3% by the girl) respectively. The average number of questions per students was 2.6 while the female students raised 2.8 questions which was more than the average 2.5 questions by male students. It was the 4th grade female student cluster, which raised the most question (3.0) while the 6th grade male students raised the least question (2.4) in average. 3. The questions raised by the children could be divided into seven categories of the knowledge need on sex. They were Reproduction (310 questions, 25.9%), Sexual Culture (230, 19.2%), Concept of sex (125, 18.0%), Changes of Puberty (172, 14.4%), Sexual Health (119, 10.0%), Anatomy and Physiology of Reproductive System (78, 6.5%) and Sexual Tendency and behavior (71, 5.9%). 4. 'Reproduction' was the most frequently raised questions not only by both sex groups but also by the 5th grade students. Both sexes in the 4th grade showed the highest interest in Sexual Culture while it was Changes in Puberty for the both sexes in the 6th grade. The knowledge need on sex of the children indicated what they understand sexuality. They apprehended sex as sex, gender and sexuality in an inclusive way. They showed a major interest in the biological sex and the sexual activities. It seems that the children managed to understand clearly the meaning of gender, furthermore, they even pointed out that the streotyped sex role, patrimonial system and the sexual discrimination were unreasonable. The students possessed not only the least but also the most negative understanding in regard of sexuality. Two suggestions were made from the above conclusions for the practical sex education as well as its research. 1. For the practice: The sex education for the elementary upper grade school student should be relevant with their cognitive characteristics, also it should be more specific on the reproductive organs of both sexes, the actual scenes of the pregnancy and child delivery procedures. The gender concept should be added to the biological sex education, which will lead them to understand the unreasonableness of today's male-superior phenomenon and correct them. It is also necessary to develop educational programs for this age group so as to help them to understand sex in the sense of sexuality as well. 2. For the research: It is not easy to draw out a through conclusion since this study was carried out as one-time data collection. Yet it is undeniably helpful for the sex education if we can understand what the children want to know about sex, how much they know about it by conducting deep-interview researches through a small number of sample.

        수확후 처리제로서 Benomyl 과 Bitertanol 이 처리된 사과의 저장조건에 따른 잔류량

        이은주,김장억 ( Eun Joo Lee,Jang Eok Kim ) 한국환경농학회 1996 한국환경농학회지 Vol.15 No.4

        This study was conducted to clarify the degradation pattern, safety evaluation and penetration ratio of benomyl and bitertanol to apple used as postharvest fungicides during CA(controlled atmosphere) and cold storage. In CA storage, the degradation of benomyl and bitertanol in stored apple was slow at the early stage, while that in cold storage was, on the contrary, faster at the early stage. The initial concentrations of benomyl and bitertanol in apples applied at the standard application concentrations were 2.24 and 1.54㎎/㎏, respectively, and their residual amounts were below the maximum residue limits, 1㎎/㎏ at 135 and 96 days in CA storage, 115 and 70 days in cold storage, respectively. The half-lives of benomyl and bitertanol in stored apples were 124 and 130 days in CA storage, 101 and 111 days in the cold storage, respectively, indicating that the degradation was faster in cold storage than in CA storage. The residual amount of benomyl and bitertanol in stored apples was retained more in peels than in pulps of apples.

        Ni/Cu 전극을 적용한 고효율 실리콘 태양전지의 제작 및 특성 평가

        이은주,이수홍,Lee, Eun-Joo,Lee, Soo-Hong 한국전기전자재료학회 2004 전기전자재료학회논문지 Vol.17 No.12

        We have applied front contact metallization of plated nickel and copper for high efficiency passivated emitter rear contact(PERC) solar cell. Ni is shown to be a suitable barrier to Cu diffusion as well as desirable contact metal to silicon. The plating technique is a preferred method for commercial solar cell fabrication because it is a room temperature process with high growth rates and good morphology. In this system, the electroless plated Ni is utilized as the contact to silicon and the plated Cu serves as the primary conductor layer instead of traditional solution that are based on Ti/Pd/Ag contact system. Experimental results are shown for over 20 % PERC cells with the Plated Ni/Cu contact system for good performance at low cost.
