Collaboration and communication are the most required competencies for future students, and the expression of creativity through collaboration and communication is also very important in terms of national competitiveness. The need for research on group creativity was derived by reflecting the current status of education, future predictions, and trends in creativity research. Therefore, the purpose of this study was to examine the concept of group creativity based on the interactionist model and to analyze the effect of interaction between learners in the expression learning process on the creative performance of the group. By conducting an action research on high school students as research participants, it was examined how the interaction between learners was reflected in the creative performance of the group in the process of expression learning. To this end, educational implications were proposed by synthesizing the interaction between learners in design learning, qualitative interpretation of the practice results, and the instructor's record and reflection. Through this study, it was found that interaction between learners is important in increasing the esthetic in the process of implementing the results. 협업과 소통은 미래의 학생들에게 가장 요구되는 역량이며 협업과 소통을 통한 창의성의 발현은 국가 경쟁력의 차원에서도 매우 중요한 대목이다. 교육의 현황과 미래 예측, 창의성 연구의 동향을 반영하여 집단 창의성에 대한 연구의 필요성이 도출 되었다. 따라서 본 연구는 집단 창의성의 개념을 상호작용주의 모형 중심으로 고찰하고 이를 토대로 미술 학습 과정을 통해 실행연구를 하여, 표현학습 과정에서 학습자간 상호작용이 집단의 창의적 수행에 반영된 영향을 분석하는 것을 연구의 목적 으로 하였다. 고등학생을 연구 참여자로 실행연구를 실시하여 표현 학습 전개 과정에서 학습자간 상호작용이 집단의 창의적 수행에 어떻게 반영되는지 살펴보았다. 이를 위해서 디자인 학습에서의 학습자간 상호작용, 실습 결과물에 대한 질적인 해석, 교수자의 기록과 성찰 등을 종합하여 교육적 시사점을 제안하였다. 본 연구를 통해 결과물을 구현해 내는 과정에서 학습자간 상호작용은 정교성 요인을 높이는데 중요함을 알게 되었다. 결론적으로 미술 표현 학습 과정에서 집단 창의성을 발현하기 위해서는 아이디어 발상 단계도 중요하지만 그 이후의 단계인 시각화, 정교화, 표현 단계가 고루 중요한 단계이기 때문에각 학습 단계별로 학습자간 상호작용이 활발히 이루어질 수 있도록 교수자의 적절한 안내와 피드백이 동반되어야 함을 강조 하였다.

Purpose: This study aimed to identify research topics in the emergency medical technician (EMT) field and examine research trends. Methods: In this study, 261 research papers published between January 2000 and May 2022 were collected, and EMT research topics and trends were analyzed using topic modeling techniques. This study used a text mining technique and was conducted using data collection flow, keyword preprocessing, and analysis. Keyword preprocessing and data analysis were done with the RStudio Version 4.0.0 program. Results: Keywords were derived through topic modeling analysis, and eight topics were ultimately identified: patient treatment, various roles, the performance of duties, cardiopulmonary resuscitation, triage systems, job stress, disaster management, and education programs. Conclusion: Based on the research results, it is believed that a study on the development and application of education programs that can successfully increase the emergency care capabilities of EMTs is needed.

As you see, there's no difference of the hair's before and after Magic straight permanent on the example A's hair's thickness, the rate of the tense and the C's rate of the tense, but we can find that there are a lot of difference of the A's strength of the hair, the B's hair's thickness, the strength of the hair, the rate of the tense, the C's hair's thickness, and the strength of the hair on the before and after the Magic straight permanent. That is to say, there are more damage on the condition of normal hair than the one after the Magic straight permanent. On the change of the hair's physical character, before the permanent, the hair's schedule was regular and had the healthy head skin of clear mutual boundary But after the Magic straight permanent wave, the hair's schedule changed to unregural, had unclear mutual boundary of the head skin and the schedule was taken off so the cortex showed up and so on, every condition of the damage was very heavy. On the effect of the treatment, even though it gaves the worth condition of the hair, after the Magic straight permanent formally the change of the hair gives the beautiful straight.

This study aims to derive the need for middle-aged women to consider using fashion product applications, styl- ing, and personalized styling services. To analyze the fashion styling considerations of middle-aged women, 200 women in their 40s and 50s were surveyed. Middle-aged women usually tend to shop through home shopping, department stores, fashion soho (Small office home office) malls, and open market-type applications, and purchase fashion products more than two or three times a month, spending an average of less than 50,000 won per month. Middle-aged women consider choos- ing appropriate clothing based on the occasion and place, complementing the flaws of the changed body type as well as taking into account the weather in the styling process, and seek to showcase a sophisticated, luxurious, and youthful image through styling. However, they are confused and face difficulties in fashion styling, with regard to not only overall body shape but also partial body changes, such as increasing waistline, flabby thighs and arms, and decreasing hip volume. In addition, middle-aged women were looking for expert advice on styling to help them look the best. They also wanted to solve the difficulties of making a right choice amid the overflowing information related to fashion. The results of the study contribute to identifying products that meet the needs of middle-aged women and help develop detailed consumer- tailored marketing strategies, thereby improving sales of fashion products.

유령멍게와 노랑꼭지유령멍게는 국내의 경우, 항만, 선박의 바닥, 양식장에 대량으로 발생하여 큰 피해를 입혀, 위해종으로 지정되어 있다. 따라서 이들을 이용하는 측면에서 화장품 원료로의 사용 가능성을 검토하였다. 유령멍게와 노랑꼭지유령멍게를 70% 에탄올로 추출물을 제조하여 항산화능을 측성하였다. 유령멍게와 노랑꼭지유령멍게 추출물 20 mg/mL에서 DPPH는 각각 71.80%, 21.40%를 보였고, ABTS는 각각 95.47%, 27.53%, nitric oxide 생성 억제능은 각각 97.47%, 88.90%로 나타났다. 총 페놀 함량은 유령멍게와 노랑꼭지유령멍게에서 각각 0.081, 0.041 mg gallic acid/mg extract으로 나타났다. 결과적으로 노랑꼭지유령멍게보다 유령멍게에서 다소 높은 항산화능을 보였다. 이들은 추출물은 동물성 유래 항산화물질들로 화장품 소재로서 활용 가능함을 확인하였다. Ciona intestinalis and Ciona savignyi have been designated as hazardous species because they have caused great damages as they appeared in ports, ships, and farms in Korea in large amount. Therefore, in terms of using them, the possibility of use as cosmetic ingredients was examined. C. intestinalis and C. savignyi were treated with 70% ethanol to make an extract and then their antioxidant activity was measured. C. intestinalis and C. savignyi showed 71.80% and 21.40% of DPPH at 20mg/mL of extract, respectively. ABTS was 95.47% and 27.53%, while nitric oxide production inhibitory ability was 97.47% and 88.90%, respectively. Total phenol content was 0.081 and 0.041 mg gallic acid/mg extract, respectively. As a result, C. intestinalis showed somewhat higher antioxidant activity than C. savignyi. It is confirmed that these extracts are animal-derived antioxidants that can be used as cosmetic materials.
