This paper aims to confirm whether the dance genre in crisis was vulnerable statistically and to explore and suggest the cause. In this study, the crisis includes the 2008 financial crisis and the 2020 corona period in scope of the crisis. During the financial crisis in 2008, the number of dance cases was similar to the previous year, but the number of dance performances was much less. During the 2020 corona crisis, the number of performances showed similar results to the previous year, but the share of the number of audiences and ticket sales decreased sharply. The causes include canceling major performances by organizations affiliated with the central government's performance halls, online performances without spectators, and a sharp drop in performances of the most popular classical ballet. The fact that the audience focuses on classical ballet can be said to be a task to be solved.

과정 중심 글쓰기 활동 중 동료피드백이 학습자의 영작문 능력 향상에 미치는 영향과 인식에 관한 연구

황희정 한국콘텐츠학회 2023 한국콘텐츠학회논문지 Vol.23 No.6

This study aimed to explore the effects and perception of peer feedback on the improvement of learners’ English writing proficiency in process-based writing activities. 56 student participants were formed into two groups: 30 experimental group (PG) with peer feedback on their writing, and 26 control group (CG) without peer feedback. All students completed a process-based writing task and pre/post questionnaires. The questionnaires were divided into two categories: cognitive and affective areas and consisted of 30 questions including questions related to the general characteristics of learners. After they performed a 1st draft of writing, the students in each group were randomly divided into groups of three members. The students in PG rotated the drafts of each group members and exchanged peer feedback, and the students in CG read the drafts of each group members. They revised and completed the final draft. The study found that PG significantly improved in the final draft, which proved that peer feedback affected the improvement of learners’ English writing proficiency. It was also revealed that the students generally perceived peer feedback as helpful and showed positive changes in their attitude toward it. The findings imply that peer feedback should be valuable in process-based writing classes. Based on the findings, pedagogical implications were suggested. 본 연구의 목적은 과정 중심 글쓰기 활동 중 동료피드백이 학습자의 영작문 능력향상에 미치는 영향과 그에 대한 인식을 확인하는 것이다. 연구참여자는 56명의 대학생으로 동료피드백을 교환한 실험집단 30명과 동료피드백 교환하지 않은 통제집단 26명이었다. 모든 학생들은 과정 중심의 글쓰기 과제를 수행하였고 사전·사후 설문조사에 참여하였다. 설문 항목은 인지적 영역과 정의적 영역의 두 가지 범주로 나누고 학습자의 일반적 특성 관련 질문을 포함하여 30문항으로 구성하였다. 초안 작성 후, 집단별로 무작위로 3인 1조로 나누어 실험집단은 자신의 조에 속한 동료의 초안을 읽고 피드백을 교환하였고, 통제집단은 동료의 초안을 돌려 읽기만 하였다. 두 집단 모두 초안을 수정하여 최종안을 완성하였다. 연구 결과, 실험집단이 작성한 최종안이 훨씬 향상되었으며 이를 통해 동료피드백이 학생들의 영작문 실력향상에 효과적임이 입증되었다. 또한 두 집단 모두 동료피드백이 글쓰기에 도움이 되었던 것으로 인식하였고 긍정적인 태도를 보였다. 본 연구 결과는 동료피드백이 과정 중심의 작문 수업에 활용할 가치가 있음을 함의한다. 이러한 결과를 근거로 교육적 시사점을 제언하였다.

Background and Objectives: Several predictors of recurrence of atrial fibrillation (AF) after ablation have been identified, including age, type of AF, hypertension, left atrial diameter and impaired left ventricular ejection fraction. The aim of this study was to investigate whether the atherosclerotic plaque thickness of the thoracic aorta is associated with a recurrence of AF after circumferential pulmonary vein ablation (CPVA). Subjects and Methods: Among patients with drug-refractory paroxysmal or persistent AF, 105 consecutive (mean age 58±11 years, male : female=76 : 29) patients who underwent transesophageal echocardiography and CPVA were studied. The relationships between the recurrence of AF and variables, including clinical characteristics, plaque thickness of the thoracic aorta, laboratory findings and echocardiographic parameters were evaluated. Results: A univariate analysis showed that the presence of diabetes {hazard ratio (HR)=3.425; 95% confidence interval (CI), 1.422-8.249, p=0.006}, ischemic heart disease (HR=4.549; 95% CI, 1.679-12.322, p=0.003), duration of AF (HR=1.010; 95% CI, 1.001-1.018, p=0.025), type of AF (HR=2.412, 95% CI=1.042-5.584, p=0.040) and aortic plaque thickness with ≥4 mm (HR=9.514; 95% CI, 3.419-26.105, p<0.001) were significantly associated with the recurrence of AF after ablation. In Cox multivariate regression analysis, only the aortic plaque thickness (with ≥4 mm) was an independent predictor of recurrence of AF after ablation (HR=7.250, 95% CI=1.906-27.580, p=0.004). Conclusion: Significantly increased aortic plaque thickness can be a predictable marker of recurrence of AF after CPVA.

Background and Objectives: We assessed the ability of portable echocardiography (with contrasts) to clearly delineate the cardiacstructure, and evaluated the impact of its use on the diagnosis and management of critically ill patients in Korea. Subjects and Methods: We prospectively enrolled 123 patients (mean age 66±16 years), who underwent portable transthoracicechocardiography (with contrast) for image enhancement at 12 medical centers. The quality of the global left ventricular (LV) images, thenumber of the regional LV segments visualized, the ability to visualize the LV apex and the right ventricle (RV), and any changes in thediagnostic procedure and treatment strategy were compared before and after the contrast. Results: Of the 123 patients, 52 (42%) were using mechanical ventilators. The amount of poor or uninterpretable images decreased from48% to 5% (p<0.001), after the contrast. Before the contrast, 15.6±1.1 of 16 LV segments were seen, which improved to 15.9±0.6segments (p=0.001) after the contrast. The ability to visualize the LV apex increased from 47% to 94% (p<0.001), while the inability toclearly visualize the RV decreased from 46% to 19% (p<0.001). Changes in the diagnostic procedure (for example, not requiring othertypes of imaging studies) were observed in 18% of the patients, and the treatment plan (medication) was altered in 26% of patients afterthe contrast echocardiography. Conclusion: The use of a contrast agent during the portable echocardiography, in intensive care settings, can improve the image qualityand impact the diagnostic procedures and treatment for Korean patients.

초등학생이 지각한 가족응집성 및 가족적응성이 자살생각에 미치는 영향: 회복탄력성의 매개효과

황희정,이주영 한국상담심리학회 2016 한국심리학회지 상담 및 심리치료 Vol.28 No.3

The purpose of this study was to examine the effects of family cohesion and family adaptability on elementary school students’ suicidal ideation and to identify the mediation effect of resilience. A total of 424 5th and 6th grade students from 3 schools in Seoul and Daegu participated in the study. Correlation analysis showed significant correlations among family cohesion, family adaptability, 3 subscales of resilience, and suicidal ideation. In path analysis, only positiveness, one of the 3 subscales of resilience, fully mediated the effect of family cohesion on suicidal ideation. Self-regulation ability and interpersonal ability did not show significant mediating effects while family-cohesion directly affected suicidal ideation. In conclusion, family cohesion is a meaningful predictor of children’s suicidal ideation and resilience and, positiveness, serves as an important mediating factor between vulnerable family function and suicidal ideation. 본 연구에서는 초등학생이 지각한 가족응집성 및 가족적응성이 자살생각에 미치는 영향을 확인하고 회복탄력성의 매개효과를 검증하고자 하였다. 서울과 대구에 위치한 3개 초등학교 5, 6학년 424명을 대상으로 자료를 수집하여 상관분석과 경로분석을 실시하였다. 첫째, 가족응집성 및 가족적응성, 회복탄력성의 하위요인인 자기조절능력, 대인관계능력, 긍정성은 자살생각과 유의미한 상관이 있는 것으로 나타났다. 둘째, 가족응집성 및 가족적응성과 자살생각 간의 관계를 매개하는 변인으로 회복탄력성의 하위요인 3개를 각각 검증한 결과, 긍정성만 유의한 매개효과를 나타냈다. 자기조절능력과 대인관계능력의 매개효과는 유의하지 않았으며, 가족응집성만이 자살생각에 직접적인 영향을 미치는 것으로 나타났다. 회복탄력성의 하위요인인 긍정성 모형에서는 가족응집성이 긍정성을 통해서만 자살생각에 간접적으로 영향을 미쳤다. 이러한 결과는 가족응집성이 초등학생의 자살생각에 영향을 미치는 유의한 예측 변인임을 보여주며, 회복탄력성을 구성하는 개념 중 긍정성이 가족응집성과 자살생각의 관계를 매개하는 중요한 변인임을 보여준다. 본 연구의 결과는 초등학생의 자살생각을 예방하기 위해서는 긍정성에 초점을 맞춘 회복탄력성의 증진이 중요함을 시사한다. 높은 회복탄력성은 취약한 가족체계 하에 있는 아동들을 자살생각의 위험으로부터 보호해주는 기능을 할 것으로 기대된다.

Recovery of hesperidin and narirutin from waste Citrus unshiu peel using subcritical water extraction aided by pulsed electric field treatment

황희정,김희주,고민정,정명수 한국식품과학회 2021 Food Science and Biotechnology Vol.30 No.2

The objective of this study was to identify whether the efficacy of extracting hesperidin and narirutin from Citrus unshiu peel by-products can be increased by combining pulsed electric field (PEF) and subcritical water extraction (SWE). The samples were treated with a PEF at a strength of 3 kV/cm for 60 and 120 s. Subsequent SWE was conducted at extraction temperatures of 110–190 °C for 3–15 min. The concentration of hesperidin was highest at 46.96 ± 3.37 mg/g peel (dry basis) after PEF treatment at 120 s, combined with SWE at 150 °C for 15 min, while that of narirutin peaked at 8.76 ± 0.83 mg/g after PEF treatment at 120 s, integrated with SWE at 190 °C for 5 min. The concentrations of both hesperidin and narirutin increased with PEF treatment time. The PEF increased the amounts of hesperidin and narirutin extracted by 22.1% and 33.6%, respectively. This study demonstrate the potential of PEF pretreatment for enhancing the SWE of flavonoids from C. unshiu peel.

인공호흡기를 부착한 급성 호흡부전 환자에서 페병변 부위에 따른 체위적용이 동맥혈 가스분압 및 폐포동맥간 산소 분압차에 미치는 영향

It is widely recognized that manipulation of body position takes advantage of the influences of gravity for improving oxygenation. The study aims to determine the effects of positioning(supine, prone, right lateral decubitus and left lateral decubitus positions) applied to the mechanically ventilatory acute respiratory failure patients on arterial oxygen partial pressure(PaO2) , alveolar arterial oxygen tension difference(AaDO2) , mean aterial pressure, peak inspiratory pressure and plateau pressure. Thirty two acute respiratory failure patients admitted to the medical intensive care unit at Kangnam St. Mary's Hospital. The Catholic University of Korea from March 1997 to January 1998, were divided into three groups by radiographic evidence of unilateral or bilateral lung disease. In group 1 with dominant right lung disease were twelve subjects, group 2 with dominant left lung disease had eight subjects and group 3 had twelve subjects with bilateral lung disease. The variables were measured in 30 minutes after each position of supine, prone, good lung down lateral decubitus and sick lung down lateral decubitus position. The position order was done at random by Latin squre design. The results are as follows; 1) With group 1 patients, the PaO2 in the left lateral decubitus and prone position were 126.8±30.8 mmHg and 106.7±36.8 mmHg, respectively (p = 0.0001). 2) With group 2 patients, the PaO2 in the prone and the right lateral decubitus position were 121.7±44.7 mmHg and 118.5±31.7 mmHg, respectively (p = 0.0018). 3) With group 3 patients, the PaO2 was 143.6±36.6 mmHg in the prone position (p =0.0001). 4) With group 1 patients, the AaDO2 in the left lateral decubitus and the right lateral decubitus position were 178.1 ±29.7 mmHg and 233.1±24.4 mmHg, respectively(p = 0.0001). 5) With group 2 patients, the AaDO2 in the prone and the left lateral decubitus postion were 184.0±39.5 mmHg and 231.0±23.9 mmHg, respectively(p = 0.0019). 6) With group 3 patients, the AaDO2 in the prone and the supine postion were 377.1±35.6 mmHg and 435.7±13.1 mmHg, respectively (p = 0.0001). 7) There were no differences among the mean arterial pressure, peak inspiratory pressure and plateau pressure for each of the supine, prone, left lateral decubitus and right lateral decubitus position. The results suggest that oxygenation may improve in mechanically ventilatory patients with unilateral lung disease when the position is good lung dependent and prone, and patients with bilateral lung disease when the position is prone without any effects on the mean arterial pressure and airway pressure. It is suggested that body positions improve ventilation/perfusion matching and oxygenation need to be specified in patient care plans.
