본 연구에서는 산화갈륨의 방열 특성 향상을 위해 산화갈륨/다이아몬드 이종 박막 성장을 진행하였다. 먼저, 핫필라멘트 화학기상증착법을 이용하여 다결정 다이아몬드를 증착시킨 후, 미스트 화학기상증착법을 통해 450~600℃ 사이의 온도구간에서 산화갈륨 박막을 성장시켰다. 열처리 전후 비교를 통해 500℃에서 산화갈륨/다이아몬드 계면 분리 현상이 발생함을 확인하였다. 이는 비정질과 결정질이 혼재된 산화갈륨 박막이 성장된 후, 냉각 과정에서 열팽창계수의 차이로 인해 계면이 분리된 것으로 판단하였다. 따라서, 본 연구를 통한 산화갈륨/다이아몬드 계면의 물리적 안정성을 통해 산화갈륨의 열물성 보완및 고전력 반도체로의 활용이 기대된다. In this study, Ga₂O₃/diamond layers were grown on Si substrates to improve the thermal characteristics of Ga₂O₃ materials. Firstly, diamond thin film was grown on Si substrates by hot-filament chemical vapor deposition. Afterward, Ga₂O₃ layer was grown in the growth temperature range of from 450~600℃ by mist chemical vapor deposition. We found that layer separation happens at the Ga₂O₃/diamond interface at the growth temperature of 500℃. This is attributed to the different thermal expansion coefficient of the mixture of amorphous and crystalline structures during cooling process. Therefore, this study might contribute to the heat-sink-layer bonded power semiconductor applications by stabilizing the thermal properties at Ga₂O₃/diamond interface.

학습자의 진로탐색에 있어 경험중심 무용교육의 역할과 과제

서지연(Seo Ji Yun),박순자(Park Soon Ja) 학습자중심교과교육학회 2017 학습자중심교과교육연구 Vol.17 No.19

최근 경험을 통한 교육이 강조되며 학습자의 경험에 기반을 둔 경험중심 교육이 주목받고 있다. 이에 따라 무용교육에서도 진로와 경험에 관한 연구들이 비중 있게 수행되어 왔다. 하지만 학습자의 진로탐색에 있어서 경험중심 무용교육이 필수적임에도 불구하고, 현행연구에서 진로와 경험중심 무용교육을 상관지어서는 논의되지 않고 있다. 이에 따라 경험중심 교육의 의미 및 경험중심 무용교육의 교육적 기능, 중·고등학교의 진로교육 현황 내용 분석을 하였다. 연구결과, 무용교육은 체육교과에 속해 직접경험이 아닌 간접경험으로 진행되어 학습자에게 감성교육으로서 진로 역량을 주지 못하고 있으며, 단계적이지 못한 일회성 교육으로 이루어져 체험을 통한 역량개발과 미래를 대비하는 다양한 경험중심 무용교육이 부족한 실정으로 학습자의 진료탐색에 있어서 교육적인 역할을 못하고 있다. 이에 본 연구는 학교예술교육 활성화를 통한 경험중심 무용교육을 실천하기 위해 예술영역으로서 직접무용프로그램의 개발, 연속적인 무용교육을 위한 동아리활동 및 지역사회의 협조와 운영콘텐츠의 개발, 진로연계를 위해 전문적인 무용교수법의 연구에 대한 과제를 제시한다. 이러한 학습자의 진로탐색을 위한 경험중심 무용교육의 역할과 과제를 보안 할 수 있는 융. 복합적 적용 방안에 관한 후속연구와 이에 대한 지속적인 활발한 논의가 필요하다. Recently, education through experience is emphasized, and experience-centered education based on learners experience has been in the spotlight. Accordingly, even in dance education, researches on careers and experiences have been heavily carried out. Accordingly, this study aims to explore the role of dance education in depth and present a task to offer experience-centered dance education in learners s career exploration. For this, the study analyzed the meaning of experience-centered education, the educational function of experience-centered dance education and the present condition contents of career education of middle and high schools. The results are as follows. Since dance education belongs to a physical subject and is offered as an indirect experience, not a direct experience, it does not give learners career competencies as a sensibility education, and since it consists of an antiphasic one-time education, competence improvements through experiences and various experience-centered dance educations for the future are lacked, it does not play an educational role in learners career exploration. Thus, it presents a task for researching a professional teaching method of dance for direct development of a dance program as an artistic area, club activities for continuous dance education, the community s cooperation, developing operation contents and a connection with career to offer an experience-centered dance education through vitalizing school art education. Therefore, follow-up studies on an integral, complex application method to complement the roles and tasks of experience-centered dance education for learners career exploration and continuous and active discussions of this are needed.

The purpose of the study is to suggest educational meaning that can contribute to improvement of elementary dance education in the future, analyzing and applying direct experience of John Dewey`s empirical theory to elementary dance education, the content system of the curriculum was analyzed throngh the present state of elementary dance education. Accordingly, to encourage quantitative and qualitative development of elementary dance education, the study discussed educational meaning that can contribute to improvement of elementary dance education in the future, analyzing and applying direct experience of John Dewey`s empirical theory and content system of the curriculum was analyzed throngh the present state of elementary dance education. As human grows through experiences, education also aims at growth. Therefore, it can be known that growth of experiences and education is essential and inevitable. Elementary dance education is divided to two groups of 1st ~ 2nd grade and 3rd ~ 6th grade so that the contents of class are quite comprehensive. As a result, actual dance education for students shows basic level of expression of movement. This requires improvement into detailed contents of dance class. Accordingly, students can encourage growth of experiences through variable dance education. And for effective elementary dance education, it is necessary to conduct dance education focusing on experiences through direct experiences, not indirect experiences in the integrated education or dance education. Dance education through direct experiences needs professional teaching skill. Accordingly, teaching of teacher with professional dance education should be made so that systemized dance education can be done to draw students` interest and thinking through dance education. Elementary dance education through such experiences can play basic and important role in whole school dance education. So much systematic and theoretical investigation is necessary to make educational meaning be known. This could contribute to the formation of independent dance subject.

Objectives: Investigate the situation of Joseon Dynasty`s Acupuncture and Moxibustion. Methods: the Acupuncture and Moxibustion methods in UiRimCh`walYo (醫林撮要 "Essentials of Oriental Medical Doctors") were studied. Results and Conclusions: First of all, the Acupuncture and Moxibustion methods in UiRimCh`walYo are narrated according to specific symptoms Like diarrhea and stomachache, and not organized by the origin of illness or some abstract nature of a disease. In addition, it excluded complicated Acupuncture and Moxibustion methods, only adopting a couple of Acupuncture Bleeding methods and Moxibustion methods to simplify the technique as much as possible. Secondly, the Acupuncture and Moxibustion methods in UiRimCh`walYo, along with those in DongUiBoGam and Ch`imGuYoGyol introduce ways to perform moxibustion on the Umbilical Middle and Elixir Field. By focusing on the similarities between the three comtemporary medical works, it is possible to assume the existence of a unique acupuncture method using moxibustion on the Umbilical Middle and Elixir Field. Thirdly, the Acupuncture and Moxibustion methods in UiRimCh`walYo didn`t go into detailed differentiation of symptoms and just concisely described one or two treatment methods for each symptom and simplified the prescription down to the core acupuncture points. This shows that the Acupuncture and Moxibustion methods in UiRimCh`walYo didn`t seek its own cure but was edited in order to act as an appendix to Herbal Medicine. When integrating the conclusions above, it can be said that UiRimCh`walYo strived to use acupuncture and moxibustion simply and effectively inside the Oriental medicine`s Large boundaries of Herbal Medicine and Acupuncture and Moxibustion. Harmony with Herbal Medicine, an easy-to-find organization, and simple, easy-to-do prescription are what UiRimCh`walYo was about.

Objectives: Balhae was a Kingdom forming the Period of Southern and Northern Kingdoms with Shilla. Because there have been paid little attention to the medicine of Balhae in the medical history field, we have little information on the medicine of Balhae thoroughly in detail. The aim of this study was to explorer on the acupuncture and moxibustion in Balhae as a part of the study on the medicine of Balhae. Methods: Because the historical remains of BalHae is not sufficient, it is hard to find out the part directly related to medicine However, the study established the category of acupuncture and moxibustion based on two rational frames from both diachronic and synchronic respects. Results: BalHae succeeded to the unique tradition and manufactured excellent needles which is harmless to human body. And BalHae`s acupun`cture was the highest level in those days by succeeding to the tradition from Gogugryeo. There might have been the Bi-Bo idea that we can treat country`s disease with the Bo-sa (補瀉) theory of acupuncture in BalHae. Conclusions: We could know that there has been many medical scriptures of our own in BalHae. We could find out that BalHae succeeded to the legitimacy of our native medicine from Gojosun to Goguryeo and that they had the highest Acupuncture and Moxibustion in those days.
