        합창반주자의 핵심역량에 대한 지휘자와 반주자의 인식조사

        이슬,최진호 한국음악교육공학회 2017 음악교육공학 Vol.- No.32

        The purpose of this study was to identify the perceived factors affecting the competence of choral accompanists as a choral conductor and choral accompanist(n=65). The results of this study indicated that the musical communication skill with choral conductor, the preparation for choral rehearsals, the ability of playing piano with exact rhythm, the cooperative attitudes were the most influential factors affecting the competence of choral accompanists. Also, choral conductors and accompanists indicated that piano techniques to adjust tone color including the effect of orchestral sound for the choral works were the essential factors for choral accompanists. Other important factors affecting the competence of choral accompanists were the sight-reading skills and the ability that manages a panic situation during the performance. Recommendation and conclusion were provided for choral accompanists. 본 연구의 목적은 국내에서 활동하는 합창 지휘자와 반주자를 대상(n=65)으로 합창 반주자가 갖추어야 할 핵심적인 역량이 무엇인지 알아보는 것이다. 본 연구결과를 통해 얻은 결론은 다음과 같다. 첫째, 지휘자와 반주자들이 생각하는 합창 반주자가 갖추어야 할 가장 중요한 핵심역량은 지휘자와 음악적으로 호흡하는 능력이었다. 그 다음으로 반주 연습을 해오는 성실한 태도, 연습 시간에 늦지 않는 책임감 있는 태도, 정확한 리듬으로 연주하는 능력, 협동·화합하는 자세인 것으로 나타났다. 둘째, 피아노 반주자가 갖추어야 할 피아노 테크닉에 관하여, 지휘자와 반주자들은 합창 사운드와 맞는 피아노의 톤 칼라, 다양한 피아노 터치를 사용한 곡의 해석에 맞는 표현력, 그리고 피아노 반주의 관현악적 효과와 분위기를 만드는 것 등을 중요한 요소로 인식하는 것으로 나타났다. 셋째, 지휘자와 반주자들은 합창 반주자의 핵심역량 중 피아노 초견 능력 또한 중요한 요소로 인식하고 있었다. 마지막으로 연주 시 발생하는 돌발 상황에 대처하기 위해 합창 반주자가 준비해야 하는 역량은 순발력과 암보능력이었다.

        금속 적층제조된 대형 실린더 부품의 열변형에 미치는 적층 높이 및 재료 특성 영향에 관한 해석

        이슬비(Seulbi Lee),방태양(Tae Yang Bang),김우종(Woojong Kim),강민철(Mincheol Kang),최윤석(Yoon Suk Choi) 대한용접·접합학회 2021 대한용접·접합학회지 Vol.39 No.3

        The laser powder bed fusion technique involves depositing layers by selectively melting a material. This leads to rapid melting and solidification, followed by repeated reheating and remelting. The complex thermal hysteresis and resultant thermal gradient inevitably cause thermal stress and distortion in additively manufactured products. The thermal stress and distortion lead to dimensional inaccuracies, defects such as delamination and cracking, and finally, adverse effects on the product life. In this study, a thermomechanical analysis of a large cylinder (hollow shape, with a height of 750 mm, an outer diameter of 500 mm, and a thickness of 20 mm) was performed using the finite element method to investigate the effects of building height and material properties on thermal distortion. Specifically, the evolution of thermal distortion was systematically interpreted with the thermal hysteresis. Depending on the building height of the cylinder, the thermal hysteresis was influenced by the bed plate and the thermal effect of the predeposited and postdeposited layers. In addition, the thermal distortion tendencies of Ti-6Al-4V and Inconel 718 metal powders were examined based on the material properties, particularly thermal diffusivity. The maximum thermal distortion occurred at approximately 100 mm below the top surface of the cylinder for both materials. Moreover, the thermal distortion of the Ti-6Al-4V was more significant than that of Inconel 718 because of the lower thermal diffusivity of the former.

        지방교육자치 과제별 역량 분석 연구: 순위합법을 중심으로

        이슬아(Seul A Lee),한은정(Eun Jung Han) 교육종합연구원 2024 교육종합연구 Vol.22 No.2

        요약: 이 연구는 지방교육자치의 추진 과정에서 각 시도교육청이 갖추어야 할 역량을 보다 실제적인 맥락에서 살펴보기 위하여, 지방교육자치 추진 과제별로 필요 역량과 이들 중 중요 역량을 도출하는 것을 목적으로 하였다. 이를 위해 학계와 현장 전문가를 대상으로 하여 전문가 인식 조사를 실시하고, 순위형 다중응답분석 방법 내 순위합법 방식으로 그 결과를 분석하였다. 연구 결과, 첫째, 지방교육자치 과제 추진을 위해 지방교육행정기관이 갖추어야 할 역량은 과제별로 다양하며, 차이가 있는 것으로 나타났다. 둘째, 기관, 조직, 개인 차원의 역량이 모두 필요하지만 특히 개인의 역량이 보다 많이 중요 역량으로 분석되어, 선행연구에서 개인 단위의 역량이 강조되어 온 것과도 유사한 결과를 보여주었다. 셋째, 법령 및 재정과 관련한 일부 특수한 과제를 제외하고는, 지역과 학교를 이해하고 소통하는 것을 바탕으로 정책을 기획하고 이들을 지원하는 역량이 중요한 것으로 분석되었다. 이러한 연구 결과는 지방교육자치를 성공적으로 추진하기 위해서는 주체별 역량을 규정하는 접근이 아니라, 각 추진 과제별 중요 역량에 초점을 두고 이를 계발할 필요가 있음을 보여준다. 또한 지방교육자치의 추진 방향이 학교나 지역교육의 자율화와 다양성 제고에 있으며, 지방교육행정기관이 이들과 소통하고 협업하면서 이를 촉진할 수 있도록 지원하는 역할을 수행해야 함을 시사한다. In order to examine the competencies that each provincial and local education office should possess in the context of promoting local education autonomy, this study aimed to identify the essential competencies required for each task associated with advancing local education autonomy. The survey of experts' perception was conducted, and the results were analyzed using the ranking method within the ranking multi-response analysis method. The study revealed that the competencies necessary for local educational administrative agencies to carry out tasks related to local educational autonomy vary by task. While competencies at the institutional, organizational, and individual levels are all deemed essential, individual competencies were identified as particularly crucial. These results align with previous emphasis on the significance of individual competencies. Furthermore, with the exception of specialized tasks related to laws and finances, the ability to plan and support policies through understanding and communication with regions and schools was highlighted as vital. These findings show the importance of key competencies for each initiative to promote local educational autonomy. They also indicate that local educational autonomy involves bolstering the autonomy and diversity of schools and local education, with local education administrative agencies assuming a pivotal role in facilitating communication and collaboration to advance these objectives.

        A Case of Idiopathic Hypomagnesemia with Hypocalcemia Presenting as Generalized Tonic-Clonic Seizure

        이슬,권아름,채현욱,김호성 대한소아내분비학회 2011 Annals of Pediatirc Endocrinology & Metabolism Vol.16 No.3

        Hypomagnesemia may arise from various disorders such as renal magnesium wasting, familial hypomagnesemia, inadequate intake and increased gastrointestinal loss. Hypomagnesemia and hypocalcemia were found in a month- old female patient with generalized tonic-clonic seizure. Twenty-four hour urine collection samples were used to assess renal magnesium wasting; fractional excretion of 24-hr urine magnesium was less than 1.45%, i.e., within the normal limits. The patient had no history of chronic diarrhea or failure to thrive, which supports the conclusion that intake was adequate. She had no family history of hypocalcemia, hypomagnesemia, or seizures. Here, we report a case of idiopathic hypomagnesemia.

        The Relationship Between Stress and Anxiety Towards Viral Epidemics and the Turnover Intention of Clinical Dental Hygienists

        이슬,장종화 융합연구학회 2022 융합연구학회지 Vol.6 No.1

        The purpose of this study is to examine and understand the stress, anxiety, job stress, burnout, and turnover intention perceived by clinical dental hygienists under pandemic situations caused by viral epidemics, and analyze the interrelationship and related factors influencing the clinical dental hygienists’ turnover intention. An online survey was conducted to measure the extent of stress and anxiety towards the viral epidemics targeting clinical dental hygienists, and 204 clinical dental hygienists serving at dental hospitals and clinics participated. The pearson correlation analysis was performed, and the stepwise multiple regression analysis was performed for the factors influencing the turnover intention. The results of this study demonstrated that the stress and anxiety towards the viral epidemics turned out to be exhausted (r=0.30, p<0.01), job stress (r=0.28, p<0.01), and turnover intention (r=0.19, p<0.01), reflective of a significant positive correlation. The factors influencing the turnover intention were emotional fatigue from burnout (p=0.23, p=0.001), job stress (p=0.48, p<0.001), and bachelor’s degree (p=0.14, p=0.008). The adjusted explanatory power of this model was 44%, respectively. Given the current situation where the COVID-19 epidemic has prolonged, it would be necessary to provide sufficient rest, provide a safe work environment, and apply work stress relief and management program to reduce the turnover rate of the clinical dental hygienists.
