Activate charcoal (AC) can be utilized as a soil conditioner in agricultural crop areas. This study was conducted to investigate the effect of AC on growth and yield of Zingiber mioga ROSC as affected by different amounts of AC. The results obtained are summarized as follows. Growth characteristics including plant height and leaf length were the highest when activated charcoal added with 10-30%, suggesting that optimum amount of activated charcoal was ranged from 10 to 30%. Growth and enlargement of the root were improved by 10% AC with higher rhizome length and weight.

초등학교 음악교생 지도교사의 경험에 대한 내러티브 탐구 : 초등 음악교사 양성 프로그램의 개선에 주는 시사

최윤경 이화여자대학교 교육과학연구소 2009 교육과학연구 Vol.40 No.1

음악교육의 다양한 현상과 본질을 살펴보기 위해서는 다양한 연구 방법을 통한 접근이 필요하다. Clandinin과 Connelly는 20여 년간 교사의 교육 경험을 연구하면서 내러티브 탐구(narrative inquiry)의 개념, 필요성, 절차 등을 통해 내러티브 탐구를 교육 현상의 연구 방법으로써 이론화, 체계화시켰다. 이에 본 연구에서는 질적 연구 방법의 하나인 내러티브 탐구를 적용하여 교생의 음악 수업 지도 경험에 대한 초등 교사의 이야기를 듣고 현장 텍스트(field texts)를 구성하였다. 세 초등교사의 교생 음악 수업 지도 경험에 대한 현장 텍스트의 분석을 통해 교육실습과 초등학교 음악교육의 현상을 은유하는 핵심 주제를 발견하였으며 이를 중심으로 연구 텍스트(research texts)를 작성하였다. 핵심 주제는 엔터테인먼트적인 즐거운 음악 수업만이 강조되는 현장 분위기, 교생들의 음악수업 실습 기회의 부족, 교생들의 음악 교과교육학적 지식(PCK, Pedagogical Content Knowledge)의 부족, 대학과 실습학교 사이의 의사소통 및 협력의 부족이다. 음악교육에서 내러티브 탐구의 적용은 현장에서의 실천적인 음악교육에 대한 인식과 이해를 높여주고, 대학과 학교 현장 간의 협력의 필요성을 보여준다. The approach through the diversity of research methods is needed to examine the varied state and nature of the music education. While Clandinin and Connelly studied a teaching experience for 20 years, they theorized and systematized a narrative inquiry as a research method of the actual state of education through the concept, necessity, and procedure of a narrative inquiry. In this study, field texts were constructed by listening to teachers' teaching experience for student teachers through the adoption of a narrative inquiry. Principal subjects that were the metaphor of the practicum and the actual state of a music education in elementary school were found through the analysis of field texts. Subsequently, research texts were constructed around principal subjects. Principal subjects were as follows: 1. Entertaining factors were only emphasized in elementary music class. 2. Student teachers do not have sufficient practical training for music class during practicum. 3. Student teachers were short of Pedagogical Contents Knowledge(PCK). 4. Communication and cooperation between the university of education and elementary school were insufficient. The adoption of narrative inquiry in music education increased the recognition and understanding for practical music education and showed the necessity of cooperation between university and elementary school.

DBME(Discipline-Based Music Education)에 의한 음악과 교육과정의 비판적 분석과 발전 방향 탐색

최윤경,강현석 이화여자대학교 사범대학 교육과학연구소 2005 교육과학연구 Vol.36 No.2

오늘날 음악 교육은 입시 위주의 교육 정책, 국가 경쟁력의 강화라는 표어 아래에서 학교 당국과 교사, 학생, 학부모에게 부담스러운 과목으로 외면당하고 있으며, 음악 교육의 가치와 당위성마저 흔들리는 위기에 직면해 있다. 이러한 위기는 현재까지의 음악 교육이 일반적으로 ‘음악 이론과 기능을 가르치고 음악 활동을 하는 교과’로 인식되어 왔고, 음악과 교육과정 역시 ‘이해해야 할 지식’과 ‘경험해야 할 행위와 활동’을 단순히 나열하고 있었기 때문이라고 할 수 있다. 우리나라와 비슷한 위기에 직면했던 미국은 예술 교육의 정상화를 위해 미술교육에서 DBAE(Discipline-Based Art Education) 이론을 개발하였고, DBAE의 연구 결과에 기초하여 음악 교육의 문제를 해결하고자 연구된 것이 DBME(Discipline-Based Music Education)이다. 이에 본 연구는 DBME의 역사적 배경, 목적과 내용, 특징을 살펴보고, 이를 통해 현행 음악과 교육과정을 비판적으로 분석하였으며, 향후 음악과 교육과정이 ‘사회적?역사적?문화적 맥락을 고려’하고, ‘사고와 탐구 활동을 강조’하고, ‘디지털 중심의 사회적 변화를 수용’하는 음악과 교육과정으로 발전하여야 함을 제안하였다. Today, music education is a burden to teachers, students and parents and music is recognized to difficult subject. The reason is why the purpose of education changes into the university entrance and the policy of economic growth has precedence. So, The value of music education have faced at risk. The reason is that music education was recognized by subject matter that teaches music theory and function and does music activity until now. And music curriculum lists knowledge to understand, and activity to experience. The United States of America that faced at risk similar our country developed DBAE(Discipline-Based Art Education) theory in art education to solve problem of art education. DBME(Discipline-Based Music Education) is based on DBAE and studied to solve problem of music education. DBME involves music-making, musical history, musical aesthetics and musical criticism. Each of these disciplines are related and integrated to provide students with a balance understanding of works of music. This study examines historical background, purpose, contents, characteristic of DBME for theoretical explanation. Through this, current music curriculum is analyzed critically. And the direction of music curriculum is presented as following. So Music curriculum that accommodates engineering, considers social, historical, cultural context, and emphasizes thinking ability is emphasized in the next music curriculum revision.

음악교육에서 내러티브의 활용 방안 연구

최윤경 이화여자대학교 교과교육연구소 2008 교과교육학연구 Vol.12 No.3

최근 우리나라 음악교육의 문제점은 학생의 삶의 맥락과 유리된 음악적 지식과 기능의 습득을 강조함으로써 인간과 음악이 따로 떨어져 있다는 것이다. 이러한 문제점을 해결하기 위해 개정 음악과 교육과정에서는 사회적·문화적 맥락에서의 음악에 대한 이해를 통해 음악의 생활화, 사회에서의 음악의 역할 및 기능을 강조하고 있다. 이러한 개정 음악과 교육과정의 정신은 내러티브를 통해 구현될 가능성이 크다. 왜냐하면 내러티브는 인과관계와 관련된 행위들을 하나의 의미 있는 전체로 구성하여 각각의 사건이나 경험들을 서로 연결시키는 총체적, 맥락적 이해를 특징으로 하기 때문이다. 따라서 본 연구에서는 현행 우리나라 음악교육의 문제점을 해결하고 개정 음악과 교육과정의 정신을 구현하기 위한 하나의 대안으로서 내러티브를 상정하고 음악 수업의 소재로서 내러티브의 활용 방안과 음악 교사의 설명 방식으로서 내러티브의 활용 방안을 제시하였다. 음악교육에서 내러티브의 활용 방안은 다음과 같다. 첫째, 음악 수업 소재로서 일화, 설화, 전기, 음악 비평을 도입함으로써 제재곡 위주로 진행되던 음악 수업 자료를 다양화시키고 음악에 대한 흥미를 높일 수 있다. 둘째, 음악 교과서의 서술을 보완하고 학생들의 음악에 대한 이해를 돕기 위해 음악 용어, 가사 내용, 음악에 대한 배경을 설명할 때 교사의 설명 방식으로서 내러티브의 활용 방안을 제시하였다. 본 연구에서는 내러티브의 활용 방안을 구체적으로 나타내기 위해 내러티브의 활용 방안을 세분하여 제시하였지만, 실제 수업에서는 제재곡의 특성이나 지도할 음악 개 념에 따라 몇 가지 방식이 함께 사용되며, 여러 가지 활용 방안을 함께 적용함으로써 학생들의 음악적 이해의 향상을 도모하여야 한다. The emphasis of the learning of musical concepts and musical skills instead of the understanding of other disciplines and backgrounds related to music led to a decreased interests of music classes to students. To solve these problems, contextual understanding, social roles and the value of music have been emphasized at the revised music curriculum. Accordingly, I have supposed the narrative as the an alternative for a solution to those problems and a realization of the spirit in a revised music curriculum. Two methods for application of the narrative in music education is studied as follows. First of all, the narrative is used as subject materials of music class. The narratives of anecdotes, tales, biography, autobiography, music criticism, etc. diversify the materials of music class. The limitation of musical work-centered existing class in the view point of materials is solved by utilizing various narrative materials. Second, the narrative is used as a method of explanation for music teachers. That is, the narrative is used to musical understanding when musical terms, the words, and the backgrounds of musical works are explained. Even though the method for a practical use of the narrative is classified into small groups in this study, several methods have to be applied together according to the characteristic of work or the concept of music to teach. As well as, the improvement of musical understanding of students should be contrived by applying several methods together.

Choi,Seong-Kyu,Yun,Kyeong-Won,Chon,Sang-Uk,Seo,Young-Nam,Seo,Kyoung-sun,Kwon,Byung-Sun 한국자원식물학회 2003 Plant Resources Vol.6 No.3

This study was conducted to produce effectively more leaves of Angelica acutiloba through year-round production system by using various mulching materials and polyethylene(PE) tunnel. Soil temperature by covering treatment was higher in PE mulching and PE tunnel than in rice straw mulching, especially showing the highest temperature in PE tunnel from April through May. Water content of soil was higher in PE mulching than in non-mulching. Leaf production of Angelica acutiloba through year-round production showed the highest in PE tunnel and root production in PE mulching. These results suggest that leaf production of Angelica acutiloba can be maximized through PE tunnel cultivation system.

Background : The purpose of this study was to investigate the incidence of unplanned endotracheal extubation and to identify the influencing factor of unplanned extibation in ICUs for providing baseline data in developing prevention strategies and administrative standards. Methods : the 942 intubated ICU patients information from March,2000. to February,2001 in a tertiary university hospital was used as a source of data from the medical records and hospital information system. In order to analyze factors related to unplanned extubation, the subjects of this study were divided by unplanned extubation group and planned extubation group and were matched by its sex, age, and disease groups in a ratio of one to two. The data were analyzed by descriptive statistics, x^(2)-test. T-test, Fisher’s exact test, and logistic regression analysis with SPSSWIN 10.0 program. Result : 1) Forty-seven(4.99%) of 942 intubated patients experienced unplanned extubation 65 times during the twelve-month period. Thirty-four(72.34%) of 47 unplanned extubated patients required reintubation, whereas thirteen patients(27.66%) did not. 2) About half of unplanned extubation(46.8%) occurred during the night shift. 3) As for the nursing activity, respiratory nursing activity score(P=.0.06) and total nursing activity score(P=.011) showed statistically significant differences between unplanned extubation group and planned extubation group. 4) As for the patients status, unplanned extubation group showed more lower consciousness level(P=.000), more irritable or agitated behavior(P=.000), and had more apllied physical restraints(P=.000) than planned extubation group. 5) As for the untubation related variables, unplanned extubation group revealed more untubated with respiratory failure(P=.000), more dependent on mechanical ventilation(P=.015) than planned extubation group. 6) Factors affecting unplanned extubations in intensive care unit patients were irritable or agitated behavior(odds ratio-13.757), night shift(odds ratio=7.166), and mechanical ventilation(odds ratio=6.257) from conditional logistic regression analysis. Conclusion : The most affecting factor of unplanned extubation was agitated or irritable behavior. Therefore the results of this study could be helpful to ICU nurses for meticulous care, decision making, timely intervention, and development of intervention strategies for preventing unplanned extubation.

The purpose of this study was to investigate the association among nutrient intakes and health-related lifestyles with cardiovascular disease risk assessed by blood lipid profile according to Apolipoprotein E genotypes. Middle-aged industrial male workers who had completed their annual medical examination were recruited and data of 675 subjects who finished the nutrient survey were used in the analysis. Anthropometric parameters, dietary assessment (FFQ), health-related lifestyles and blood profiles were used for statistical analyses. Apo E genotype groups were classified into the following three genotypes: Apo E2 group (including E2/E2, E2/E3, E2/E4), Apo E3 group (including E3/E3), Apo E4 group (including E3/E4, E4/E4). The frequency of Apo E2, E3, and E4 allele were 13.3%, 75.0% and 11.7% respectively. There were no significant differences in the anthropometric parameters depending on different Apo E genotypes. Also, no significant differences in the nutrient intakes were found according to the genotype groups. The nutrient intakes of all subjects were similar to or higher than the level of KDRIs (Dietary Reference Intakes For Koreans) except for intakes of calcium (67.44% of KDRIs), vitamin A (73.83% of KDRIs) and vitamin B2 (78.02% of KDRIs). Also, there were no significant differences of health-related lifestyles according to Apo E genotype groups. As for the lipid profiles, Apo E4 group had significantly higher total and LDL-cholesterol concentrations than the Apo E2 group (p < 0.05). We confirmed that plasma total and LDL-cholesterol concentrations were greatly influenced by Apo E genotypes. However, nutrient intakes and health-related lifestyles were not associated with Apo E genotypes.

기질레진의 조성에 따른 복합레진의 물리적 성질에 관한 연구

이연신,최경구,박상진 大韓齒科保存學會 2002 Restorative Dentistry & Endodontics Vol.27 No.1

Current composites are made with dimethacrylate monomers and silane-treated silica microfillers, either alone or with silane treated glass fillers. The main reasons for clinical failure of dental composites are secondary caries, wear and fracture. Most of practitioner want to get a composite which is more tougher under occlusal stress, less polymerization contraction, and better handling properties in application clinically. The aim of this study was to investigate the influence of resin matrix with various flows on the physical properties such as facture toughness and degree of conversion of the experimental resins. It was hypothesized that flexible or tough resin compoties can be designed by judicious choice of monomer comptosition Various flow resin matrices containing Bis-GMA, UDMA, and TEG-DMA were made by altering the proportion of the monomers. After the unfilled resins were light-cured for different light intensity. the fracture toughness(K_1c) was measured according to ASTM standard using the the single edge notched geometry, and degree of conversion(DC) was measured by FTIR. And experimental composites were formulated with variations in the proportion of silanated quartzz and strontium glass fillers as 60, 75, and 77wt%. Also, the physical properties of composites with various filler contents were evaluated as same manner. All resulting data were compared by ANOVA/Tukeys test at 0.05 level. The results were as follows; 1. The degree of conversion of high flow resin containing less Bis-GMA was higher than that of low flow unfilled resin. 2. While the degree of conversion of unfilled resin was increased according to light intensity for polymerization, there was no significant increase with moderate and high light intensity. Also, the fracture toughness was not increased by high light intensity 3. The fracture toughness was high in the flow unfilled resin containing higher contents of Bis-GMA. 4. There was a significant increase for fracture toughness and a tendency for degree of conversion to be reduced when the content of fillers was increased. 5. In the experimental composites, the flow of resin matrix did not affected on the fracture toughness, even, which was decreased as increase of viscosity. These results showed that the physical properties of a dental composite could be attributed to the flow of resin matrix with relative content of monomers. Specific combination of resin monomers should be designed to fulfill the needs of specific indication for use.
