목적 본 연구에서는 예비 정보교사를 대상으로 스토리텔링 기반 실생활 문제해결 인공지능 융합교육 프로그램을 적용하고 교육적 효과성을 창의융합역량을 중심으로 검증하였다. 방법 이를 위해 설계한 스토리텔링 기반 실생활 문제해결 인공지능 융합교육 프로그램을 정보·컴퓨터 교원 양성과정 전공 교과목의 일부로 적용했으며, 실험 처치 전-후 연구 대상자의 창의융합역량을 비교하여 효과성을 검증하였다. 결과 사전-사후 검사에 대한 대응표본 t 검정 결과 창의융합역량에 통계적으로 유의미한 향상이 확인되었으며, 각 하위요인에서도 통계적으로 유의미한 차이가 확인되었다. 또한 문항별로 살펴보았을 때도 59개 문항 중 56개 문항에서 실험처치 전후로 통계적으로 유의미한 향상을 확인하였다. 결론 예비 정보교사 대상의 스토리텔링 기반 실생활 문제해결 인공지능 융합교육은 예비 또는 현직 정보교사를 위한 인공지능 융합교육 연구가 매우 부족하다는 점에서 의의를 가진다. 그러나 정보교사는 학교 현장에서 인공지능 융합교육의 중심축 역할을 수행하므로 인공지능 융합교육에 대한 이해가 바탕이 되어야 하며, 이에 지속적으로 관련 연구가 이루어질 필요가 있다. Objectives In this study, the storytelling-based real-life problem-solving artificial intelligence convergence education program was applied to pre-service Informatics teachers, and its educational effect was verified by focusing on confluence competency. Methods The storytelling-based real-life problem-solving artificial intelligence convergence education program was implemented as a major subject of the Informatics teacher training course, and the effectiveness of the program was confirmed by comparing the students' creativity confluence competency before and after the experimental treatment. Results As a result of the paired-sample t-test for the pre-post tests, a statistically significant improvement was confirmed both in creativity confluence competency and each sub-factor. In addition, when looking at each item, statistically significant improvements were confirmed before and after the experimental treatment in 56 of the 59 items. Conclusions The storytelling-based real-life problem-solving artificial intelligence convergence education for pre-service Informatics teachers is meaningful in that research on artificial intelligence convergence education for pre-service or in-service Informatics teachers needs to be revised. However, Informatics teachers play a significant role in artificial intelligence convergence education in the school field, so understanding artificial intelligence convergence education should be the basis, and related studies must be conducted continuously.

본 논문에서는 현직 초·중등 교사의 인공지능 융합교육 역량 강화 및 소양 함양을 위한 인공지능 소양교육 프로그램을 개발하고 이를 적용하여 인공지능 융합교육 관심도에 미치는 영향을 검증하였다. 검사도구는 Hall et al.(1979)의 관심중심수용모형을 기반으로 George, Hall & Stiegelbauer(2006)이 개발한 관심단계 설문 척도를 사용하였다. 인공지능 소양교육 프로그램 적용 전, 후 인공지능 융합교육에 대한 관심도를 분석한 결과, 프로그램 적용 전, 후 모두 비사용자의 유형이 나타났으나 전반적인 관심도는 적용 전에 비해 상승하였다. 인공지능 소양 교육 프로그램의 만족도 결과를 분석한 결과 대부분의 영역에서 만족한다는 응답이 도출되었으나, 인공지능과 산업의 융합 및 적용 사례에 대해서는 다소 만족도가 떨어지는 경향이 나타났다. In this paper, we developed an artificial intelligence literacy education program to strengthen the AI convergence education capacity and cultivate literacy of in-service elementary and secondary teachers, and verify the effect on the degree of interest in artificial intelligence convergence education by applying it. As a test tool, the level of interest questionnaire scale developed by George, Hall & Stiegelbauer(2006) was used based on the center of interest acceptance model of Hall et al.(1979). As a result of analyzing the degree of interest in artificial intelligence convergence education before and after the application of the artificial intelligence literacy education program, the types of non-users were found both before and after the application of the program, but the overall degree of interest increased compared to before application. As a result of analyzing the satisfaction result of the artificial intelligence literacy education program, a response that was satisfied in most areas was derived, but there was a tendency to be somewhat less satisfied with the case of convergence and application of artificial intelligence and industry.

In order to investigate the distribution of phytoplankton community in the coastal waters of the Chuksan Harbor, East Sea, the abundance and biomass of phytoplankton have been evaluated through seasonal interval sampling from April 2000 to October 2002. A total of 363 different phytoplankton species was observed and most of them were composed of diatoms. The mean abundance and chlorophyll-a concentration of phytoplankton during the study period ranged from 56 ${\times}$ $10^3$ to 720 ${\times}$ $10^3$ cells $L^{-1}$ and from 0.78 to 3.29 μg chl-a $L^{-1}$, respectively. The relative contribution of the size-fractionated phytoplankton to phytoplankton community showed difference according to seasons. The average contribution of nano-phytoplankton(<20 $\mu$m) was over 50% in the total abundance and biomass of the phytoplankton. Our results show that nano-phytoplankton play an important role in the southern coastal waters of the East Sea. And the environmental factors such as suspended substances, phosphates and silicates were positively correlated with the abundances and biomass of phytoplankton.

본 연구에서는 교육대학원의 인공지능 융합교육 전공에서 필요한 교과목 개설을 위해 교육 수요자의 요구사항을 분석하였다. 분석결과 새로운 전공에서 배우기를 원하는 교사 중 66%는 프로그래밍, 인공지능에 대한 경험이 없었지만, 블록형 프로그래밍 언어를 활용해 본 경험은 있는 것으로 나타났다. 대부분의 교사들은 이론과 실습이 적절하게 혼합된 수업 방법을 희망하였으며 초등학교의 경우 언플러그드 활동, 플랫폼 활용 AI 체험, 블록형 프로그래밍 언어를 활용한 AI 구현 및 프로젝트 구현을 요구하였다. 중 · 고등학교의 경우 플랫폼 활용, 블록형 프로그래밍 언어 활용, 텍스트 프로그래밍 언어 활용, 피지컬 컴퓨팅을 통한 구현, 담당 교과와의 융합과 같은 주제들에 대한 필요성이 높게 나타났다. 인공지능의 원리, 인공지능 구현, AI 활용 프로젝트 구현, AI와 교과 융합에 대한 교사들의 요구에는 상호 유의한 상관관계가 있었다. 이러한 수요자의 요구분석을 수용한 인공지능 융합교육 전공과목들은 ‘인공지능 소양’, ‘기초 인공지능 제작 및 심화’, ‘인공지능 융합 교과교육’ 모듈로 구성될 수 있음을 제안하였다. In this study, the requirements of education consumers were analyzed for the establishment of major courses in AI convergence education in the graduate school of education. As a result of the study, 66% of all teachers have no experience in programming or AI, but they have used block programming languages. Most teachers demanded instruction method in which theory and practice were properly mixed. In the case of elementary schools, there are high need for unplugged activities, AI experience using platform-based programming language, AI project using block-type programming language. In middle and high schools, there exist high need for using block-type programming language, using text programming language, implementation through physical computing, and convergence with major subjects. The requests for principle of AI, implementation of AI, implementation of projects using AI, and convergence of AI-subjects education showed positive correlation. The AI convergence education major module is suggested, which accommodates the demand analysis, consists of three modules: "AI literacy", "Basic & Advanced AI production", and "AI Convergence with Curriculum".

Purpose: To investigate the radiosensitivity of the normal human oral keratinocytes (NHOK), and the effect of irradiation on cell cycle and protein expression. Materials and Methods: To evaluate the radiosensitivity of NHOK, the number of colonies and cells were counted after irradiation and the SF2 (survival fraction at 2Gy) value, and the cell survival curve fitted on a linear-quadratic model were obtained. LDH analysis was carried out to evaluate the necrosis of NHOK at 1, 2, 3, and 4 days after 2, 10, and 20 Gy irradiation. Cell cycle arrest and the induction of apoptosis were analyzed using flow cytometry at 1, 2, 3, and 4 days after 2, 10, and 200y irradiation. Finally, proteins related cell cycle arrest and apoptosis were analysed by Western blot. Results: The number of survived cell was significantly decreased in a dose-dependent manner. The cell survival curve showed SF2, α, and β values to be 0.568, 0.209, and 0.020 respectively. At 200y irradiated cells showed higher optical density than the control group. After irradiation, apoptosis was not observed but G2 arrest was observed in the NHOK cells. 1 day after 10 Gy irradiation, the expression of p53 remained unchanged, the p2l/sup WAF1/Cipl/ increased and the mdm2 decreased. The expression of bax, bcl-2, cyclin B1, and cyclin D remained unchanged. Conclusion: These results indicate that NHOK responds to irradiation by G2 arrest, which is possibly mediated by the expression of p21/sup WAFl/Cipl/, and that cell necrosis occurs by high dose irradiation.

Mediastinum is the space located between the right & left lung lobes in the center of the thorax, and contains many vital organs such as heart, aorta, trachea, esophagus, vagus nerve, lymphatics. So the infection of mediastinal space causes a serious and potentially fatal process. Like other infections, surgical drainage, aggressive antibiotic therapy and supportive care are recommended for optimal outcome. Airway management in the presence of the neck, glottic edema, elevation of the tongue is a formidible problem especially in the case from odontogenic origin. We have recently encountered such a case resulting in a number of local and systemic complications.
