        • 花粉荷(POLLEN LOAD)의 소화흡수율 및 동물성장에 미치는 영향

          李圭漢,金乙祥,朴美娥 단국대학교 1992 論文集 Vol.26 No.-

          This study was done to determine the effects of pollen load on growth, biochemical components and digestibility of protein from pollen load in rats. Weanling male rats were divided into three groups. Pollen load was given at three levels and comprising 0, 6, 12 persent of dietary protein. Consumption of pollen load 12% protein from pollen load significantly decreased weight gain(P<0.05), protein efficiency ratio(P<0.05), food efficiency ratio(P<0.05), organ weight(P<0.05), plasma protein content(P<0.05) and apparent digestibility of protein(P<0.05). However there was no difference in the protein content in the liver among three groups. The diet containing 6% protein from pollen load was better nutritional efficiency and apparent digestibility in comparison to those of 12% protein from pollen load.

        • 버들치(Rhynchocypris oxycephalus)의 vitellogenin 생성량 측정을 이용한 수중 estrogen휴 화합물의 정량분석법에 관한 연구

          김을환,이도부,한상훈,윤병수 경기대학교 부설 기초과학연구소 2005 경기대학교 기초과학논문집 Vol.18 No.1

          Vitellogenin(Vtg), a phospholipoglycoprotein precursor of egg yolk, is synthesized and secreted from the liver in response to estrogens in female fish. Vtg is normally undetectable in the blood of male fish, but can be induced by exposure to chemicals possessing estrogenic activity. Thus, the presence of Vtg in blood of male fish can serve as a useful biomarker for assessing previous exposure to estrogenic compounds. In the present study, Vtg was abnormally expressed in Rhynchocypris oxycephalus treatment of Estradiol Benzoate (E_(2)). As the result, it was found that the level of Vtg in blood from R. oxycephalus was increased by treated quantity of E_(2) with dose-effect manner.

          고을한,이한동 서울産業大學校 1995 논문집 Vol.41 No.1

          Color is basically important in our life because it not only plays a role as a visual media but also provokes the human being into emotional action. That is, we can recognize, classify and utilize much information around us by using our color sense. In order to properly apply color so that we can get the upmost effect of color, we must pursue reasonable color arrangement by means of understanding functions of color. According as the improvement of product functional quality due to the technical development consumer requests for satisfactory design for goods as much as functional one. Color has worth for being as an esthetic factor and also as an essential part in our life. Nowadays importance of design has been increased among elements which are deciding factors in ranking product quality. Especially the role of design in electronics holds 60% of purchase motive factors. Besides the role of color holds the majority in design factors. Color is considerable for the fuctional side and it stimulates consumers to buy goods, color contributes enterprise to make up its good image and most of all it makes a distinction with other company's goods. The color plan of a product should be based on scientific research for being fitted our focus and turning to advantage. And it should be planned by a completely strategic progress with all goods' condition which surrounds us as well as fully expressed by their own distinction. We believe the color plan of a product sets up a co-operation between products and consumers, and increases more competitive power than others in electronics market. Therefore We hope this study will help to establish systematic and actual color plan methods and carry out color application.

          산전 세포유전학적 검사의 임상적 분석 : 서울아산병원 4년 간의 경험 Four-year Experience at Asan Medical Center

          심재윤,김성훈,김정숙,안송미,서을주,유한욱,김구환,이지영,최은영,원혜성,서대식,이필량,김암 대한산부인과학회 2004 Obstetrics & Gynecology Science Vol.47 No.3

          목적 : 1999년부터 2002년까지 4년간 서울아산병원에서 시행된 산전 세포유전학적 검사 2,372건의 후향적 분석을 통하여 최근에 시행한 검사의 적응증, 비정상적인 핵형의 유형들에 대해서 살펴보고 각각의 적응증에서 실제로 비정상적인 핵형이 관찰되는 빈도에 대해서 알아보고자 한다. 연구 방법 : 총 1,780건의 양수천자술, 455건의 제대혈천자술, 137건의 융모막 융모채취술을 통한 산전 세포유전학적 검사들을 대상으로 후향적으로 의무기록을 검토하였다. 세포유전학적 검사 결과, 산전 유전 진단의 적응증, 검사 시의 연령, 비정상적인 핵형들의 유형에 대하여 분석하였고 산전 유전 진단을 시행하게 된 각각의 적응증이 갖는 양성예측률에 대한 계산을 통하여 비정상적인 태아의 핵형을 가장 민감하게 예측해 줄 수 있는 지표에 대하여 평가하였다. 결과 : 총 2,372건의 산전 세포유전학적 검사 중 비정상 핵형이 158건에서 확인되었다. (6.7%). 산전 유전진단의 적응증에서 가장 흔한 적응증은 비정상적인 산모 혈청 선별검사이었고 (33.9%), 비정상 초음파 소견 (22.9%)과 고령 임신 (20.0%)이 그 다음으로 흔한 적응증이었다. 균형 재배열과다형성을 정상 핵형으로 간주하였을 때 비정상적인 핵형과 정상 태아 핵형이 확인된 산모의 연령에는 유의한 차이가 관찰되지 않았다 (31.9±5.3 vs. 32.1±4.5세). 균형 재배열과 다형성을 제외한 비정상 태아 핵형이 확인된 산모에서 산전 유전 진단의 가장 흔한 적응증은 비정상 초음파 소견(58.7%)이었는데, 비정상 초음파 소견이 발견되었을 때 실제로 비정상적인 태아의 핵형이 나타나는 양성 예측률은 9.9%로 확인되었다. 결론 : 본 연구의 결과는 산전 세포유전학적 진단의 여러 적응중 가운데 비정상 초음파 소견이 태아의 비정상적인 핵형을 예측하는데 가장 민감한 지표가 될 수 있음을 시사한다. Objective : To review and evaluate a total of 2,372 cases of prenatal cytogenetic diagnoses at Asan Medical Center from 1999 to 2002. Methods : We reviewed to medical records of the patients in whom the procedure for prenatal cytogenetic diagnosis was performed. A total of 1780 cases of amniocentesis, 455 cases of cordocentesis, and 137 cases of chorionic villus sampling were analyzed. The cytogenetic results, indications for prenatal cytogenetic diagnoses, maternal ages, and the profiles of abnormal karyotypes were reviewed. We calculated the positive predictive value of each indication for abnormal fetal karyotypes and evaluated a factor that was the most sensitive marker for abnormal fetal karyotypes. Results : Among the 2,372 cases of prenatal cytogenetic diagnoses, abnormal karyotypes were identified in a total of 158 cases (6.7%). The most frequent indication for prenatal cytogenetic diagnosis was abnormal maternal serum screening (33.9%), followed by ultrasonographic abnomality (22.9%) and old age (20.0%). No significant difference was found between mean maternal age with and without abnormal fetal karyotypes after excluding balanced rearrangements and polymorphisms (31.9±5.3 vs. 32.1±4.5 years). Among the 92 cases of abnormal fetal karyotypes after excluding balanced rearrangements and polymorphisms, the most frequent indication for prenatal cytogenetic diagnosis was ultrasonographic abnormality (58.7%), followed by abnormal maternal serum screening (10.9%). The positive predictive value of ultrasonographic abnormality for abnormal fetal karyotype was 9.9%. Conclusion : Among the several indications for prenatal cytogenetic diagnosis, ultrasonographic abnormality could be the most predictive marker for abnormal fetal karyotypes.
