Objective: This study aimed to verify the reliability and validity of the international patient`s satisfaction inventory, which had been previously developed, by revising and supplementing it. Methods: Toward this end, the study selected foreign patients who had received in-patient or out-patient treatments in nine hospitals in Seoul and Gyeonggi-do which run an international care center and who are fluent in either English, Russian, or Mongolian. After reviewing other satisfaction inventories in Korea and other countries that are similar to the developed satisfaction inventory and examining its validity from specialists, the study developed preliminary questions and used them for a survey. After the reliability and validity analyses as well as a consultation with specialists, the study developed the final inventory. Results: The final international patient`s satisfaction inventory consisted of seven categories and 39 questions. The seven categories were “doctor`s care (five questions),” “information and education (six questions),” “hospital environment and financial aspect (eight questions),” “hospital convenience (five questions),” “staff services (four questions),” “communication and patient-respect (four questions),” and “accessibility (four questions),” while the 39 questions included “overall satisfaction,” “whether to use the service again,” and “whether to recommend the service to others.” Cronbach`s alpha coefficient of the 7 categories, 36 items was .95, and the reliability coefficient of “doctor`s care,” “information and education,” “hospital environment and financial aspect,” “hospital convenience,” “staff services,” “communication and patient-respect,” and “accessibility” was .83, .88, .85, .85, .77, .86, and .65, respectively. Conclusion: The results of this study showed that the previously developed international patient`s satisfaction inventory offered high reliability and validity in measuring the satisfaction level of foreign patients who visit medical facilities in Korea. It is believed that using the developed satisfaction inventory to measure the experience of foreign patients will ultimately contribute to the quality of medical services to foreign patients.

The purpose of this study was to determine the physicochemical properties of esculin-hydroxypropyl-β-cyclodextrin (HPCD) inclusion complex. A host-guest inclusion complex of esculin (6,7-dihydroxycoumarin-2-one 6-β-D-glucoside) with HPCD was prepared to improve the solubility of esculin. HPCD, a highly water soluble β-cyclodextrin (β-CD) derivative, was synthesized by the substitution of the hydroxyl groups under high pressure condition. β-CD has only limited water solubility, whereas HPCD showed high water solubility and could also dissolved in solvents such as methanol, ethanol, dimethylformamide, and dimethylsulfoxide. The physicochemical properties of the host-guest inclusion complex of esculin with HPCD were investigated by using 1H-nuclear magnetic resonance (NMR), 13C-NMR, differential scanning colorimetry, and X-ray diffraction. HPCD could improve the various physicochemical properties of cosmetic ingredients such as their aqueous solubility and chemical stability. The result suggested that this complex could be a good host-guest system for functional cosmetics.

최윤경 ( Yun Kyoung Choi ) 한국예술교육학회 2012 예술교육연구 Vol.10 No.3

PCK는 교사의 교수 활동 과정에서 가장 잘 드러나는 실천적 지식이기 때문에 음악 교과의 PCK도 실 제 음악 수업의 관찰 및 분석을 통해 그 실체를 파악할 수 있다. 이에 본 연구에서는 초등학교 음악 창작 수업에 나타난 교사의 PCK 사례들을 PCK의 구성 요소인 ‘교육과정 지식’, ‘학생 이해 지식’, ``교수 전략 지식``으로 분류하여 분석하였다 ``교육과정 지식``은 ``학습 목표와 학습 활동의 관련성``, ``학습 목표 도출을 위한 동기 유발의 적절성``, ‘교육과정 재구성’ 관점으로 범주화하였고,‘학생 이해 지식’ 은 · 학습자의 수준을 고려한 학습 과제 및 평과’ 학생 활동에 대한 피드백의 적절성``. ‘감상 관점의 제시 및 감상 기 회의 제공’ 의 관점으로 범주화하였으며. ``교수 전략 지식`` 온 ``교수 용어의 적절성’. 학습 자료의 적절성 및 이용의 효율성’. ‘판서의 적절성``. 기타 교수 전략으로 범주화하였다, 범주화된 사례들은 강화 PCK 사례와 개선 PCK 사례로 나누어 분석하였다. 음악 수업에서 나타난 교사의 PCK 사례에 대한 연구를 통해 음악 교사의 전문성 신장을 위한 근거가 마련될 수 있고 음악교육의 이론과 실제가 모두 풍부해질 수 있다. The pedagogical content knowledge (hereunder PCK in music education can be understood by an analysis and observation of PCK in music class since the PCK is clearly proved to be the practical knowledge in teaching activity process. In this research, PCK cases from elementary music creation classes are analyzed by classifying PCK components such as ``the PCK of curriculum``, ``the PCK of students understanding`` and ``the PCK of teaching strategy``. ``the PCK of curriculum`` is categorized into three points of view such as ``relation between learning objective and learning activity``, ``appropriate motivation for drawing a learning objective``, and ``reconstruction of the curriculum``. ``The PCK of students understanding`` is categorized as ``1eaming task and evaluation considered by a level of learners``, ``pertinence of feedback to student activity``, and ``suggestions for the viewpoint of appreciation and the offer for the opportunity of appreciation``. ``The PCK of teaching strategy`` is categorized as ``pertinence of teaching terms``, ``pertinence of learning materials and efficiency of use``, ``pertinence of writing on the blackboard``, and ``other teaching strategy cases``. The categorized cases are divided by intensified PCK cases and improved PCK cases are analyzed, as a result, suggestions for the POK for teachers at elementary music creation class are proposed. Through the PCK cases study, the tactical knowledge of teachers is clearly described as a practical knowledge and then it can find the grounds to increase music teachers` specialty and enrich the theories and the practices of music education.

내러티브를 활용한 음악 학습 프로그램 개발

최윤경 ( Yun Kyoung Choi ) 한국교육과정학회 2008 교육과정연구 Vol.26 No.3

최근 음악교육의 문제점은 학생의 삶의 맥락과 유리된 음악적 지식과 기능의 습득을 강조함으로써 인간과 음악이 따로 떨어져 있으며, 음악에 대한 맥락적 이해가 고려되지 않는다는 것이다. 이러한 문제점을 해결하기 위해 개정 음악과 교육과정에서는 음악에 대한 맥락적 이해를 통한 음악의 생활화, 음악의 사회적 역할과 가치를 강조하고 있다. 이에 본 연구는 음악교육의 문제점을 해결하고 개정 음악과 교육과정의 정신을 구현하기 위한 대안으로서 내러티브를 상정하고 음악교육에서 내러티브의 활용 가능성을 구체화시키기 위해 내러티브를 활용한 음악 학습 프로그램을 개발하였다. 이를 위해 내러티브를 활용한 음악 학습 프로그램의 개발 절차를 4단계로 구안하고, 초등학교 음악 교과서에서 하나의 제재곡을 선정하여 이 절차를 적용함으로써 내러티브를 활용한 음악 학습 프로그램을 개발하였다. 그리고 내러티브를 활용한 음악 학습프로그램의 개발 및 적용상의 유의점을 제시하였다. The emphasis of the learning of musical concepts and musical skills instead of the understanding of other disciplines and background related to music led to decrease interests of music class to students. To solve these problems, contextual understanding, social roles and value of music have been emphasized at the revised music curriculum. Accordingly, I have supposed the narrative as the alternative for a solution of those problems and a realization of the spirit on a revised music curriculum and developed music learning program applied on the narrative. The development process of music learning program applied on the narrative were proposed to be divided into 4 steps. At the first step, a content knowledge is selected and materials of narrative are gathered by the analysis of a musical work. And then, a content knowledge is changed to a pedagogical content knowledge at the second step. And musical activities are determined at the third step and connecting pedagogical content knowledge with musical activities by story form at the end step. Music learning program applied on the narrative were developed through these steps and applied to the 4-th grades music class of elementary school. Finally, I have presented attention for developing and appling music learning program applied on the narrative.
