본 연구는 실행연구를 통해 만1세 영아반에서 베이비사인 활용에 관한 어려움의 개선 및 실천 전략 그리고 교사의 내면적 변화과정을 살펴보고자 하였다· 참여교사는 총 9년의 교육경력을 가지고 있었으며 자신이 베이비사인을 사용하면서 느끼는 어려움과 문제점을 개선하고 더 나은 학급 활용을 고민하고자 본 연구에 참여하였다· 자료 수집은 총 6개월간 이루어졌으며 참여교사와의 심층면담, 참여관찰 및 협의, 문서자료 수집 등이 이루어졌다· 이 과정에서 교사가 인식한 문제 및 실천 전략은 ‘획일적인 수업에서 다양하고 재미있는 활동으로’ ‘무조건적인 집중에서 관심에 기반을 둔 집중으로’ ‘독립활동에서 교육과정과의 통합으로’ 나타났다· 이를 통해 참여교사는 수업준비의 필요성에 대해 다시 한 번 생각하는 계기가 되었고 영아의 특성을 반영한 수업의 재구성 및 가정과의 연계 강화가 이루어졌다. Using an action research method, this study investigates the process of utilizing baby signs in a class for 1-year-olds and the participant teacher``s (Ms. Kim``s) experiences. Ms. Kim, working at H daycare center in M city, willingly participated in the study. Data collection consisted of 3 in-depth interviews conducted over six months, more than 10 participatory observations, 7 discussions with the teacher. Then, using analytical induction, the collected data were categorized, analyzed, and interpreted. The findings are as follows: The focuses of the first phase are making the teacher``s baby sign activities more fun and developing diverse teaching strategies. The second phase, included the emerging problem of the teacher``s anxiety concerning the children``s concentration levels. The teacher tried to keep in mind the children``s developmental characteristics and to reflect them in the classroom practices. The third phase, integrates baby sign activities into the theme-based standardized curriculum. While experiencing this action research, the teacher experienced such important changes in her beliefs and practices as becoming more serious about preparing class activities, re-constructing her teaching methods by reflecting on the developmental characteristics of infants, and strengthening the relationships with the parents.

김현미,양승덕,김현정,김영진,남순현,Kim, Hyun-Mi,Yang, Seung-Duck,Kim, Hyun-Jung,Kim, Young-Jin,Nam, Soon-Hyeun 대한소아치과학회 2002 大韓小兒齒科學會誌 Vol.29 No.4

연령과 치아 발육상태 단계와의 상관관계, 치아의 발육에 따른 치아의 이동상태를 평가하기 위하여 최근 5년 이내에 경북대학교 병원에 내원한 아동(남아 446명, 여아 326명)의 파노라마 방사선사진을 대상으로 하여, Moorrees의 기준에 의하여 하악 영구치아의 발육단계를 평가한 후, 발육단계와 연령, 치조골내 치아의 위치를 평가하여 다음과 같은 결론을 얻었다. 치아의 발육시기는 치관이 완료될 때까지 남, 여의 차이가 없었으나, 치근형성이 되면서 부터는 남아보다 여아에서 더 빨리 발육되는 경향을 나타내었다. 치관형성의 완료시점의 평균연령은 남아 여아 각각에서 중절치 3.71, 4.05세, 측절치 4.44, 4.60세, 견치 5.35, 5.11세, 제1소구치 6.62, 6.36세, 제2소구치 7.36, 7.17세, 제1대구치 3.51, 3.69세, 제2대구치 7.90, 7.64세 이었고, 치근단이 폐쇄되기 전단계인 $A_{1/2}$는 중절치 8.70, 8.18세, 측절치 9.55, 8.99세, 견치 12.48, 11.60세, 제1소구치 12.30, 12.01세, 제2소구치 12.19, 12.26세, 제1대구치 912, 8.87세, 제2대구치 12.59, 12.45세 이었다. 치조골내의 교두점 위치는 치관형성 완료시까지는 거의 변화가 없었으나, 치근이 형성됨에 따라 빠르게 교합평면을 향해 이동하였고, 치근형성 완료단계(Rc)에서 다시 움직임 없이 정체되었다. 치근단의 위치는 치관형성 시작부터 치근 1/4 형성 시까지 일정한 위치에 유지되었으나, 그 후에 급격하게 교합면 쪽으로 이동하였고, 치근 3/4 형성시점부터 비교적 일정한 위치에 유지되었다. 치아의 석회화가 시작되는 초기의 치배 위치는 견치가 가장 하방에 위치하였으며, 그 다음이 제2소구치, 제1소구치, 측절치 제2대구치, 제1대구치 순이었고, 중절치가 가장 상방에 위치하였다. The purposes of this study were to evaluate the timing of tooth calcification and the change of tooth position with tooth developmental stage on the mandibular teeth. Seven hundred seventy two children(male:446, female:326), 3 to 12 years of age were examined radiographically with panoramic film. Dental development was determined by inspecting radiographs and assigning a rating according to consecutive stages defined by Moorrees, and tooth cusp position and root terminus position were measured from the lower border of mandibular body and calculated the position index to evaluate the movement of tooth with developmental stage. The results were as follows. 1. There were no significant differences between boys and girls in the timing of calcification until crown completion, but timing of calcification tend to be faster in girls than in boys after root initiation stage. 2. In terms of mean age, crown completion of central incisor in boys and girls occurred at the age of 3.71, 4.05 years, at 4.44, 4.60 years for the lateral incisor, at 5.35, 5.11 years for the canine, at 6.62, 6.36 years for the first premolar, at 7.36, 7.17 years of second premolar, at 3.51, 3.69 years of first molar, and at 7.90, 7.64 years for the second molar respectively. Apex 1/2 closed stage of central incisor occurred at the age of 8.70 in boys, 8.18 in girls, at 9.55, 8.99 years for the lateral incisor, at 12.48, 11.60 years for the canine, at 12.30, 12.01 years for the first premolar, at 12.19, 12.26 years of second premolar, at 9.12, 8.87 years of first molar, and at 12.59, 12.45 years for the second molar respectively. 3. There was no noticeable movement of cusp tip until crown completion (Crc), but showed rapid movement toward occlusion plane after root initiation(Ri) and again maintain stable position after root completion stage(Rc). 4. Root terminus position was stable until root 1/4 formation stage(R1/4), followed by rapid movement toward occlusal plane and was stable again after root 3/4 formation stage(R3/4). 5. Developmental stage at the time of alveolar bone penetration by cusp tip varied with each of the permanent teeth. 6. Canine tooth follicle was at the lowest position in the mandibular body during the early stage of calcification, followed by second premolar, first premolar, lateral incisor, second molar, first molar and central incisor in order.

최소 삽입 손실을 갖는 국부 발진기 고조파 제거를 위한 병렬 결합 전송 선로 대역 여파기의 설계 및 제작

김현미,양승식,오현석,염경환,Kim, Hyun-Mi,Yang, Seong-Sik,Oh, Hyun-Seok,Yeom, Kyung-Whan 한국전자파학회 2007 한국전자파학회논문지 Vol.18 No.5

일반적인 여파기는 대역폭과 원하지 않는 신호들의 억압이 더 중요한 반면, 국부 발진기 여파기의 경우, 차단 주파수에서의 억압이 중요한 척도가 되며, 이 때 대역폭은 통과 대역 주파수에서 삽입 손실을 최소화하도록 설계한다. 본 논문에서는 이러한 특수성을 고려한 대역 여파기의 설계 절차를 보였다. 또한, 대역 여파기 제작 시 알 수 없는 기생 성분으로 인해 원하지 않는 결과를 야기시켜 제작 후의 조정이 이루어지게 된다. 따라서 이러한 문제점을 고려하여 Momentum에 근거한 제작 이전의 설계적인 조정 절차를 제시하였다. In this paper, we present the design procedure of BPF(Band Pass Filter) for the suppression of LO(Local Oscillator) harmonics. The required suppression at given harmonics is the key issues in such a filter design, while the bandwidth and the suppression of the unwanted signals are more important in the conventional RF filter design. In LO filter design the bandwidth is used for the minimization of the insertion loss for the desired signal. In addition, we propose the novel tuning procedure based on Momentum to consider the unknown parasitic effects, which usually are not included in the circuit design step and results in undesirable and frustrating tuning after fabrication.

The major purpose of this study was to survey the professional self concept of clinical nurses. The subjects consisted of 894 nurses who are working at 10 general hospital in Daegu, Pusan, and Kyungsang-do. The nurses were surveyed from November 22, 1996 to March 7, 1997. The data were analyzed using an SPSS/PC program. The results were as follows: 1. The average score of PSCNI was 72.11 points. And average item score was 2.67 points, this score means mid level in professional self concept. 2. A comparison of the scores for the dimensions of the PSCNI were as follows: the mean item score of professional practice, 2.76 points; satisfaction, 2.39 points; communication, 2.83 points. Thus, the score for communication was highest. 3. The relationship between general characteristics and the PSCNI showed a significant difference in regard to age(P=.000), religion (P=.012), educational level(P=.001), marital status(P=.000), period of nursing career(P=.000) and position(P=.002). But, there were no significant differences with regard to the field of work. In conclusion, this study suggests that we need to develop a program for improving professional self concept of clinical nurses.

Isocitrate Lyase Positive Serine Pathway 의 Key Enzyme 으로서의 Isocitrate Lyase

김현미,김유삼 ( Hyun Mi Kim,Yu Sam Kim ) 생화학분자생물학회 1984 BMB Reports Vol.17 No.4

Isocitrate lyase as a key enzyme of isocitrate lyase positive serine pathway was purified by the combination of DEAE-Sephacel ion exchange chromatography and Sephadex G-150 gel filtration chromatography from Pseudomonas MA grown on methylamine as a sole carbon and nitrogen source. Molecular size of the enzyme was determined to be 158,000 dalton composed of four subunits, two 40,000 and two 38,000 dalton. Optimal pH for the enzyme was 7.6. Km and Vmax were 0.2 mM and 80 μmoles/min/㎎ protein, respectively. Anions, such as SO₄^(2-), NO₃^-, HPO₄^(2-), Cl^-, and CH₃COO^- were competitive inhibitors for the enzyme activity. Succinate and its analogs, malonate and itaconate, were noncompetitive inhibitors, whereas glyoxylate and oxalate were competitive inhibitors. 3-Bromopyruvate was a strong inhibitor, indicating that sulfhydryl group is localized on or near the active site of this enzyme. Phosphoenolpyruvate known as a regulatory molecule of anaplerotic glyoxylate cycle was also a noncompetitive inhibitor for this enzyme. It suggests that phosphoenolpyruvate may play regulatory role for the induced isocitrate lyase positive serine pathway.

김현미,Kim, Hyun-Mi 대한치과기공학회 1990 대한치과기공학회지 Vol.12 No.1

The purpose of this study was to determine if homogeneity of the resin associated with benchcuring could be obtained in the curing unit as the water increased from room temperature to curing temperature. The results of the experiment were as follows : 1. Long periods of bench-curing are not necessary. 2. Bench-curing can take place in the water bath of the curing unit. When this procedure is used, the water should be far enough below the temerature at which active polymerization of the resin proceeds to allow the bench-curing to occur.

본 연구는 우황청심원을 비롯한 상용되는 20종의 한약제제를 대상으로 9종의 시토크롬 동종효소에 대한 대사능의 저해정도를 고속 스크리닝 기법을 이용하여 탐색함으로써, 한약제제와 약물의 병용으로 인한 약물 상호작용 가능성을 평가하고자 하였다. 인체 간 마이크로좀 시료에 9종의 주요 시토크롬 약물대사효소의 지표약물과NADPH-generating system및 한약제제(500 ${\mu}g/ml$)를 첨가한 후 $37^{\circ}C$에서 15분간 반응시켜 생성된 각각의 대사물을 LC/MS/MS를 이용하여 정량하여 시토크롬 동종효소 활성의 변화를 평가하였다. 그 결과 우황청심원 현탁액 및 황련해독탕 물 추출물이 각각 CYP2B6 및 CYP2D6 효소 활성을 선택적으로 강력하게 저해하였다. 이러한 결과는 약국에서 쉽게 구입할 수 있는 한약제제들 중 일부는 인체 간 시토크롬 활성 저해능을 가지고 있고, 이들 효소에 의해 대사되는 약물과의 병용 복용시 약물상호작용 발생 가능성이 있음을 의미한다. 향후 한약제제에서 저해능을 나타내는 주된 성분을 규명하여 이 성분의 저해능과 저해 기전을 살피는 노력이 필요할 것이다. We evaluated the potential of 20 herbal medications (HMs), commonly used in Korea, to inhibit the catalytic activities of several cytochrome P450 (CYP) isoforms. The abilities of 500 ${\mu}g/ml$ of aqueous extracts of 20 HMs to inhibit phenacetin O-deethylation (CYP1A2), coumarin 6-hydroxylation (CYP2A6), bupropion hydroxylation (CYP2B6), rosiglitazone hydroxylation (CYP2C8), tolbutamide 4-methylhydroxylation (CYP2C9), S-mephenytoin 4'-hydroxylation (CYP2C19), dextromethorphan O-demethylation (CYP2D6), chlorzoxazone 6-hydroxylation (CYP2E1), and midazolam 1'-hydroxylation (CYP3A) were tested using human liver microsomes. The HMs Woohwangcheongsimwon suspension and Hwanglyeonhaedok-Tang strongly inhibited CYP2B6 and CYP2D6 isoform activity, respectively. These results suggest that some of the HMs used in Korea have potential to inhibit CYP isoforms in vitro. Although the plasma concentrations of the active constituents of the HMs were not determined, some herbs could cause clinically significant interactions because the usual doses of those individual herbs are several grams of freeze-dried extracts.

김현미,최균,심광보,조남춘,박종규,Kim, Hyun-Mi,Choi, Kyoon,Shim, Kwang-Bo,Cho, Nam-Choon,Park, Jong-Kyoo 한국재료학회 2018 한국재료학회지 Vol.28 No.2

An ultra-high temperature ceramic, tantalum carbide, has received much attention for its favorable characteristics: a superior melting point and chemical compatibility with carbon and other carbides. One drawback is the high temperature erosion of carbon/carbon (C/C) composites. To address this drawback, we deposited TaC on C/C with silicon carbide as an intermediate layer. Prior to the TaC deposition, the $TaCl_5-C_3H_6-H_2$ system was thermodynamically analyzed with FactSage 6.2 and compared with the $TaCl_5-CH_4-H_2$ system. The results confirmed that the $TaCl_5-C_3H_6-H_2$ system had a more realistic cost and deposition efficiency than $TaCl_5-CH_4-H_2$. A dense and uniform TaC layer was successfully deposited under conditions of Ta/C = 0.5, $1200^{\circ}C$ and 100 torr. This study verified that the thermodynamic analysis is appropriate as a guide and prerequisite for carbide deposition.

This study was designed and undertaken to identify the degree of burden of family caregivers for patients who had a stroke as the burden is related to the ADL of the patients. The data were collected from October 3rd, 1997 to March 20th, 1998. The subjects in this study were 126 caregivers as family members and 126 patients with strokes who were hospitalized in two oriental medicine hospitals and four general hospitals located in Taegue and Pusan City. The questionnaires consisted of questions regarding burden(25 items) of caregivers and ADL (25 items) of patients with strokes. Data were analyzed using percentages, mean, t - test and ANOV A done with the SPSS program. The results of this study were as follows: 1. The score for family caregiver's burden was higher than the middle score. 2. The family caregivers' age had statistically significant differences in the degree of burden. 3. The age and sex of patients affected the burden of caregivers significantly. That is, caregivers felt more of a burden when caring for the patient group in their sixties than in any other age group and female patients created more of a burden than male patients. 4. There was a statistically significant difference in the degree of caregiver burden according to the level of patient ADL.
