To investigate biological activities in Aronia melanocarpa various drying methods were employed such as vacuum freeze drying, hot air drying and cold air drying. DPPH radical scavenging activity and ABTS radical scavenging activity of vacuum freeze dried Aronia melanocarpa was higher than hot and cold air dried Aronia melanocarpa. Vacuum freeze drying method showed the greatest contents of total phenol (15.34 g GAE/100 g), flavonoid (3.10 g GE/100 g) and tannin (2.46 g TE/100 g). Total anthocyanin content decreased to 163.52 mg C3G/100 g and 50.15 mg C3G/100 g for hot and cold air drying, respectively. Vacuum freeze-dried method increased the total anthocyanin content (743.09 mg C3G/100 g) when compared with fresh Aronia melanocarpa (163.52 mg C3G/100 g). Total proanthocyanidin content of vacuum freeze dried Aronia melanocarpa has increased to 6.21 g CE/100 g more than eight times compared with fresh Aronia melanocarpa (0.71 g CE/100 g). Chlorogenic acid and neochlorogenic acid content of vacuum freeze dried Aronia melanocarpa were higher than hot air dried and cold air dried Aronia melanocarpa, increasing about three times compared with fresh Aronia melanocarpa. These results suggested that vacuum freeze drying is optimal drying method to enhance biological activities in Aronia melanocarpa.

The purpose of this study is to identify factors which middle school students think important and are satisfied with in regards to dance classes using the IPA Importance/Satisfaction Analysis method. The result of the IPA matrix analysis of the importance satisfaction factor for good instruction in school dance education is the most important and very satisfactory Quadrant1 (8 elements), Quadrant 2 with high importance and low satisfaction (6 elements), Quadrant 3 with low importance and low satisfaction(4 elements), Quadrant 4 with low importance and high satisfaction(1 elements). Identifying the recognition of middle school students on a good dance class at school, this study would contribute to run a more practical and effective dance classroom in school education.
초등학교 저학년을 위한 데이터 수집 교육 프로그램 개발 및 적용
이슬,마대성 한국정보교육학회 2022 정보교육학회논문지 Vol.26 No.1
인공지능 교육에 대한 필요성이 대두되고 세계 각 나라에서는 인공지능 교육 전략을 발표하고 있다. 우리나라에서도 2021년 11월 발표된 ‘2022 개정 교육과정 총론 주요사항’에서 인공지능 교육이 반영되고 있다. 이러한 많은 관심과 함께 인공지능 교육과 관련한 프로그램들이 개발되고 있지만, 초등학교 저학년 학생들을 위한 인공지능 프로그램들은 찾아보기 어려운 실정이다. 본 연구에서는 초등학교 저학년을 위한 데이터 수집 교육 프로그램을 분석-설계-개발-적용-평가의 일련의 과정을 통해 개발하고, 초등학교 1학년 학생들에게 적용하여 그 효과성을 검증하려고 한다. 개발된 프로그램을 통해 학생들이 인공지능에 대해 이해하고 흥미를 느끼며, 생활 속에서 다양한 유형의 데이터를 찾아보는 과정을 통해 일상생활에서 적극적으로 데이터를 수집하는 태도를 기를 수 있을 것이라 기대한다. The need for artificial intelligence education has emerged, and countries around the world are announcing artificial intelligence strategies. Artificial intelligence education is reflected in the main points of the 2022 revised curriculum general published in Korea. Along with this interest, programs related to artificial intelligence education are being developed, but it is difficult to find artificial intelligence programs for lower grades of elementary school. This study aims to develop a data collection education program for the lower grades of elementary school through a series of analysis-design-development-application-evaluation processes and apply it to first-grade elementary school students to verify its effectiveness. Through the developed program, it is expected that students will be able to understand and feel interested in artificial intelligence, and develop an attitude of collecting data in their daily lives through the process of searching for various types of data in their daily lives.

Thyroid hormone is known to play a crucial role in implantation and embryonic development, as well as in the development of the nervous and musculoskeletal systems of fetus. In particular, thyroid dysfunction is associated with various pregnancy-related complications such as miscarriage, preterm birth, fetal growth restriction, and preeclampsia. Previous studies have primarily focus on the adverse effects of hypothyroidism on fetal neurodevelopment. However, the physiological and metabolic alterations occurring during pregnancy in thyroid physiology make it difficult to diagnose thyroid dysfunction. Therefore, obstetricians should have a comprehensive understanding of physiological changes of the thyroid and be familiar with the latest guidelines regarding the complications and management of thyroid dysfunction during pregnancy.
