Purpose: Human epidermal growth factor receptor-2 (HER-2)/neu amplification affects the cell proliferation through the modulation of multiple G1 cell cycle regulators in breast tumor cells. We performed this study to investigate whether retinoblastoma protein (pRB) and p27Kip1 were differently expressed according to the HER2 amplification status in human breast cancer. Methods: HER2 amplification was assayed by fluorescence in situ hybridization and the expression of cell cycle regulators were assayed by immunohistochemistry on 153 consecutive invasive breast cancers. The proliferative activity of breast cancer was analyzed according to the HER2 amplification and cell cycle protein expression status. Results: HER2 amplification was observed in 39 (25.5%) of 153 breast cancers. In the HER2 amplified breast cancers, the pRB expression was significantly increased (p=0.011) whereas there was no significant relationship between HER2 amplification and p27Kip1 expression. There was an inverse correlation between pRB expression and Ki-67 labeling index in the HER2 amplified breast cancers (p=0.036). In contrast, Ki67 labeling index was significantly decreased as p27Kip1 expression increased in HER2 non-amplified breast cancers (p=0.028). In HER2 non-amplified breast cancers, we could not observe any association between the pRB expression and Ki67 labeling index. Conclusion: The proliferation of the breast cancers was associated with pRB expression in HER2 amplified tumors whereas it was associated with p27Kip1 expression in HER2 non-amplified tumors. The results of the current study indicate that the cell proliferative activity of the breast cancer is under different growth signal pathways according to HER2 amplification status.

많은 연구 보고서들은 미래 사회에 필요한 중요한 핵심 역량으로서 창의성을 지적하고 있다. 음악과 교육과정에서도 음악적 능력을 기르고 창의성을 계발시키는 것을 음악교육의 일차적 목표로 삼고 있다. 이와 같이 창의성은 미래 사회를 대처하고 주도하기 위해 학습자들에게 계발시켜야 할 교육의 목적이 되고 있으며, 따라서 창의성을 계발시킬 수 있도록 하는 다양한 교수·학습 방법의 연구가 각 교과교육에서 이루어질 필요가 있다. 이에 따라 본 연구는 창의성과 음악적 능력을 기를 수 있도록 하는 음악과 교수·학습 방법을 모색하기 위해, 셴커식 분석 이론을 가창(노래 부르기) 교수·학습 방법에 적용하여 보았다. 먼저 셴커식 분석 이론의 고찰을 통하여 악곡의 근본선율과 구조적 계층, 연장(장식) 기법 등의 학습 요소들을 추출하였으며, 2007년 개정 음악과 교육과정의 가창(노래 부르기) 영역에 대한 분석을 통하여 `악보 보고 노래 부르기`와 `악곡의 특징을 살려 노래 부르기`의 활동 요소를 추출하였다. 이어서 교육학의 교육심리와 교육방법에서 제시하는 정보처리이론 및 Gagne의 이론과 모형, 음악교과의 가창중심 교수·학습 모형을 분석하여 학습자에게 학습이 일어나는 조건과 상황, 인지적 과정, 이론과 모형에서의 계열 단계 등 설계에 적용하기 위한 고려하여야 할 사항들을 추출하였다. 이러한 이론적 고찰에 의한 연구 내용을 기반으로 셴커식 분석 이론에 의한 가창(노래 부르기) 교수·학습 모형을 설계하였으며, 그 설계에 터 해서 모형을 개발하여 제시하고 설명하였다. 또한 모형의 적용 방안을 탐색하는 과정으로서 중학교의 가창 단원 하나를 선택하여 학교 현장의 단위 수업에 직접 적용할 수 있는, 본 연구를 통하여 개발된 셴커식 분석 이론에 의한 가창(노래 부르기) 교수·학습 모형이 적용된, 교수·학습 과정안을 개발하여 제시하였다. This study aims to incorporate Schenkerian Theory to teaching and learning of singing to develop a model that equips learners with creativity and a knowledge of music. Through extensive literature reviews, many factors that decide the success of music learning were identified and considered. The model in this study included content such as fundamental line, structural level, and prolongation suggested by Schenkerian Theory, as well as activities such as `read music and sing` and `sing different music` in the 2007 Revised Music Curriculum. In addition, the study reviewed Information Processing Theory in educational psychology and methodology, Gagne`s theories, and singing-focused teaching and learning models. Through the review, this study took into consideration many factors such as learning conditions, cognitive development, and system stages. Furthermore, in order to support music teachers to implement the teaching and learning model of singing based on Scehnkerian Theory, the study presented a lesson plan for a unit in a middle school music textbook.

Gelatin 액화세균의 생장억제에 관한 연구

이기성,崔榮吉,趙賢淑 漢陽大學校 環境科學硏究所 1983 環境科學論文集 Vol.4 No.-

Gelatin 을 재료로 이용하는 식품의 폐기물에서 gelatin 을 액화시키는 능력이 특히 뛰어난 4종의 세균을 분리·동정하였으며, 배지내에 NaCI, KI·I₂, CuSO₄등의 억제제를 농도별로 처리했을때 나타나는 4균주의 생존도 및 액화능의 변화를 비교·검토하였고, 생존도에 미치는 pH의 영향도 조사하였다. 또한 MIC(Minimal Inhibitory Concentration) Test를 시행하여 항생제에 대한 4균주의 MIC도 조사하였다. 그 결과는 다음과 같다. 1. 4균주중 H strain은 Serratia liquefaciens로, Y₁strain은 Enterobacter속으로, Y₂와 Y₃strain 은 Pseudomonas 속으로 동정되었다. 2. 배지내에 억제제로 NaCl을 처리했을 경우, 7% 농도에서 생장이 100% 억제되었으며, KI·I₂처리시에는 20ppm 에서부터 생장이 억제되기 시작하여 100ppm에서는 4개의 균주 모두 100% 생장이 억제되었다. CuSO₄처리시에는 100ppm에서부터 억제효과를 나타내기 시작하여 300ppm에서는 거의 100% 억제 효과를 보였다. 생존도에 미치는 pH의 영향을 살펴본 결과, pH 5.0, 5.5, 6.0에서는 대조군과 동일한 생존도를 나타냈으나 pH 4.0, 4.5 에서는 100% 생장이 억제되었다. 분리 균주들의 액화능 비교에 있어서는 H strain 이 가장 뛰어난 액화능을 나타내었다. CuSO₄와 KI·I₂를 각각 3ppm, 10ppm의 저농도로 처리했을 경우 4균주의 액화능은 대체로 10∼20% 감소되었다. 3. 액화 능력이 가장 뛰어난 H strain 의 MIC 는 Penicillin G; 1∼5 ㎍/ml, Spectinomycin; 12.5∼25㎍/ml, Ampicillin; <0.05㎍/ml, Cefobid; <1㎍/ml, Claforan; 0.02∼0.3㎍/ml, Tetra-cycline; >10㎍/ml로 나타났다. Tetracycline을 제외한 5가지 항생제에 대하여 H strain이 Y strain들에 비해 민감한 것으로 나타났다. 그러나 Tetracycline의 경우에는 H strain이 Y strain들에 비하여 저항성을 갖는 것으로 나타났다. Four strains of gelatin-liquefying bacteria were isolated from the sewage of the food using gelatin as the material. Treated with various concentration of NaCl, KI-I₂and CuSO₄in the culture medium and with various gradient of pH, viability of the four strains was examined and compared with each other. And also, gelatin liquefying ability was investigated in the normal culture condition and in accordance with the concentration of the inhibitor. Morever, MIC(Minimal Inhibitory Concentration) test for these strains was also carried out. The results were as follows: 1. Of the four isolated strains, the H strain was identified as Serratia liquefaciens, Y₁as the genus Enterobacter, Y₂and Y₃strains as the genus Pseudomonas. 2. Treating the culture medium with NaCl as the growth inhibitor, 7% concentration of NaCl inhibited completely the viability of all the isolated strains. Adding KI-I₂solution to the medium at the level of 20ppm, viability began to decrease and the inhibitory effect was shown 100% at 100ppm. Treated with CuSO₄at the level of 10ppm, viability began to decrease, and at 300ppm growth inhibition showed almost 100%. There was no significant difference in viability according to the pH gradient at the range of 5.0-6.0. However, at pH 4.0 and 4.5, 100% inhibitory effect on the growth was shown. Considered with the ability of gelatin liquefaction, the H strain among the four strains had the most rapid and strong ability in gelatin liquefaction. (That is, about 23 times more effective in gelatin liquefaction than that of Y₁strain) 3. Considered the MIC test, the H strain was more sensitive to Penicillin G(1-5 ㎍/ml), Spectinomycin(12.5-25㎍/ml), Ampicillin(<0.05㎍/ml), Cefobid(<1㎍/ml) and Claforan (0.02-0.3㎍/ml) than to those of the strains. Compared with the other strains, the H strain was more insensitive up to the level of 10㎍/ml to the minimal inhibitory concentration of Tetracycline.

연구목적 : 본 시험의 목적은 임상시험 시작전에 연구자들을 대상으로 PANSS Workshop을 통하여 PANSS, ESRS에 대한 국내에서의 표준화 작업을 구축하고 새로운 정신병 치료제인 리스페리돈의 효과와 안정성을 재확인하여 리스페리돈 사용에 대한 적정화를 이루는데 있다. 연구방법 : 1996년 4월부터 1996년 9월까지 국내 39개 대학병원 정신과에 입원중인 혹은 증상이 악화되어 입원하는 정신분열병 환자 377명을 대상으로 다시설 개방 연구를 시행하였다. 1주일간의 약물 배설기간을 가진후, 리스페리돈을 8주간 투여하였고, 기준점, 1주, 2주, 4주, 그리고 8주후에 평가되었다. 용량은 제1일에는 리스페리돈 1mg씩 1일 2회, 제2일에는 2mg씩 1일 2회, 제3∼7일에는 3mg씩 1일 2회 투여하였다. 이후 환자의 임상상태에 따라 임의로 증량할 수 있으며, 최대 일일 16mg을 초과하지 않도록 하였다. 추체외로 증상을 조절하기 위한 투약을 허용하였다. 임상증상 및 부작용의 평가는 PANSS(Positive and Negative Syndrome Scale), CGI(Clinical Global Impression) 그리고 ESRS(Extrapyramidal Symptom Rating Scale)을 사용하였다. 연구결과 : 377명중 343명(91%)이 8주간의 연구를 완결하였다. 치료 종결시점인 8주후 PANSS 총점수가 20% 이상 호전된 경우를 약물 반응군으로 정의할때, 약물반응군은 81.3%였다. 리스페리돈에 반응하는 예측인자로는 발병연령, 이전의 입원 횟수, 유병기간이 관련 있었다. 리스페리돈은 1주후부터 PANSS양성, 음성, 및 일반정신병리 점수상에 유의한 호전을 보여 효과가 빨랐다. CGI의 경우도 기준점에 비해 1주후부터 유의한 감소를 나타내었다. ESRS의 경우, 파킨슨 평가점수는 기준점과 비교해 투여 1주, 2주, 4주후 유의하게 증가되었다가 8주후 기준점과 차이가 없었다. Dystonia 평가점수는 1주후만 유의한 증가를 보였으며, dyskinesia 평가점수는 유의한 차이가 없었다. 혈압, 맥박수의 생명징후 및 일반 혈액학 검사, 생화학적 검사, 심전도 검사에서 유의한 변화는 없었다. 결 론 : 이상의 다시설 개방 임상 연구를 통해 리스페리돈은 정신분열병 환자에서 양성증상뿐만 아니라 음성증상 및 전반적인 증상에도 효과적인 것으로 사료된다. 보다 명확한 평가를 위해서는 다른 항정신병약물과의 이중맹검 연구가 필요할 것으로 생각되며, 또한 장기적 치료에 대한 평가도 함께 이루어져야 하겠다. Objective : The purpose of this study was to investigate the efficacy and safety of risperidone in the treatment of Korean schizophrenic patients. Method : This multicenter open study included 377 schizophrenic patients drawn from 39 university hospitals. After a wash-out period of 1 week, the schizophrenic patients were treated with risperidone for 8 weeks and evaluated at 5 points ; at baseline, and 1, 2, 4 and 8 weeks of treatment. The dose was increased from 2mg/day(1mg twice daily) to 6mg/day(3mg twice daily) during the first week and adjusted to a maximum of 16mg/day over the next 7 weeks according to the patient's clinical response. Medication to control extrapyramidal symptoms was permitted. The psychiatric and neurological status of the patients was assessed by PANSS, CGI, and ESRS scales. Results : 343(91%) of 377 patients completed the 8-week trial period. Clinical improvement, as defined by a 20% or more reduction in total PANSS score at end point, was shown by 81.3% of patients. The predictors of response to risperidone were associated older age, shorter duration of illness, fewer previous hospitalization. Risperidone had rapid onset of action ; a significant decrease of the total PANSS and three PANSS factor(positive, negative, general), and CGI was already noticed at the end of first week. For the ESRS, parkinsonism rating scores were significantly increased until week 4 comparing with baseline. Dystonia rating scores were significantly increased until week 1, and dyskinesia rating scores were not significantly changed during the study. Laboratory parameters including vital sign, EKG, hematological, and biochemical values showed no significant changes during the trial. Conclusions : This study suggests that risperidone is generally safe and effective against both the positive and negative symptoms in our group of patients.

In order to investigate the pharmacological properties of New Wonbang Woohwangchungsimwon Liquid (NSCL), effects of Wonbang Woohwangchungsimwon Liquid (SCL) and NSCL were compared. In isolated rat aorta, NSCL and SCL showed the relaxation of blood vessels in maximum contractile response to phenylephrine (10^-6M) regardless to intact endothelium or denuded rings of the rat aorta. Furthermore, the presences of the inhibitor of NO synthase and guanylate cyclase did not affect the relaxing effect of NSCL and SCL. NSCL and SCL inhibited the vascular contractions induced by acetylcholine, prostaglandin endoperoxide or peroxide in a dose-dependent manner. In conscious spontaneously hypertensive rats (SHRs), NSCL and SCL significantly decreased heart rate. NSCL and SCL, at high doses, had a negative inotropic effect that was a decrease of left ventricular developed pressure and (-dp/dt)/(+dp/dt) in the isolated perfused rat hearts, and also decreased the contractile force and heart rate in the isolated rat right atria. In excised guinea-pig papillary muscle, NSCL and SCL had no effects on parameters of action potential such as resting membrane potential, action potential amplitude, APD_90 and V_max at low doses, whereas inhibited the cardiac contractility at high doses. These results suggested that NSCL and SCL have weak cardiovascular effects with relaxation of blood vessels and decrease of heart rate, and that this effect is no significant differences between cardiovascular effects of two preparations.

韓國의 社會敎育行政에 관한 一硏究

趙誠一,金蓮起 建國大學校 敎育硏究所 1976 論文集 Vol.1 No.-

The conception of Social Education is summarized as follows: 1. In generality, Social Education means the exceptional activities of education, which is normally recognized as regular system of national education in school 2. The Social Education is systematic activities in education, clear and systematic national educational object and content and deviced educational activities. 3. The Social Education is ought to obtain with real life and improvable development. 4. The Social Education is an independent action of study by an active intention and it's objection of study to be attained by himself, but neither to be obligated nor impelled. The Social Education is achievable by not only the study in school, but adjusting by high level of industrial technics, variety of occupations, developments of industry and civilization, infliction of knowledgement and then, in this point in Korea it's neccessitated in order to adjust the transient social environment in a dire need. The administration of Social Education is the operation of cooperated and systematic group action in order to obtain the aim of social education in constitution and encourgement. For this objection it's attributable to the service activities as arrangement, instruction and supervision of man and materials. The characteristics of administration in social education ought to be considered the reactional method actively according to the variety and privilleges of social education assisting all groups activities of social education. In Korea the organization of administration in social education has not an indepentent law or regulation and attribute to a fragment. For instance, Central Organization has the social educational bureau and section in the Ministry of education and district organization has the social educational section and port in the educational committee in the provinces and cities. These educational bureau and section control the establishment, abolishment, instruction and supervisions of Junior Public school, High Public school, Private Seminary. Financial administration of Social Education maintains the expenses to support the activities of social education by the country or the public committee. The fund of social education has been allocated only 0.2% among of the budget of Ministry of Education, never been excess 0.2% of it. The problems of administration of social education to be summarized briefly as follow: 1) The legal law of social education has not been constituted in order to carry out and support the administration of social educational operations. 2) The organizations of central and district are not specialized for the efficiencies and liebilities. 3) The contents of administration of social education are not specified only inclined to govern. 4) The organizations attained social education are not in a close contact each other in publicity. 5) The fund support of budget for social education is too scanty. 6) The most of nation has scarce chances to obtain social education systematically and steadily. In this view point, we have to realize the important neccessity of social education and solve urgently those above problems in order to progress the development of our society.
