A lot of efforts have been made to develop a new technology for efficient distance education based on a powerful Internet service like World Wide Web. By developed distance education systems, we can study something we want at anytime and anywhere. However in spite of the excellent achievements we have made, something insufficient still is remained. Distance education methods only depending on static homepages or voices and simple drawings may be insufficient to support as much effects as in real class. So it is necessary to develop a new method for teaching students more feasibly and efficiently In this paper, we try to design and implement a lecture authoring system that offers effective distance education with voices, animations, camera images, drawings and etc.. We can expect the designed system can give more efficient education effects like a face-to-face lecture in real class. The enclosed function of intense compression enables to transmit the lectures more speedily. Besides it has caption processing function to serve additional informations to students with caption texts, messages and hyperlinks.

본 연구에서는 해부학강의에 있어 혼합강의의 적용가능성을 평가하였다. 2007~2009년 매 1학기동안 강원대학교 의과대학 간호학과 학생(n=143)을 대상으로 해부학강의를 가상강의 9회, 면대면 강의 3회, 사체해부실습 2회로 구성된 혼합강의로 실시한 후 설문을 통해 자기평가요인(만족도, 난이도, 흥미도, 유용성, 평가의 적절성, 학업성취도, 운영의 적절성, 이론실습연계성), 학업성취별 자기평가요인, 자기평가요인간의 상관관계를 분석하였다. 자기평가요인의 난이도는 평균$2.96{\pm}0.63$점으로 전반적인 강의수준은 적절했던 것으로 나타났고 나머지 모든 요소들은 평균 3.82~4.21점 사이로 평가되어 간호학과에서 해부학강의를 위한 혼합강의의 적용이 매우 긍정적인 것으로 나타났다. 학기종료 후 화보한 최종성적을 기준으로 세 그룹(상위, 중위, 하위)으로 나누어 자기평가요인과의 관계를 분석한 결과, 모든 요소에서 통계적으로 유의하지 않았다(p>0.05). 자기평가요인 간의 상관관계는 난이도와 전공연계성의 유용성(r=0.300, p<0.0003),혼합강의의 유용성(r=0.210, p<0.0137), 평가의 적절성(r=0.323, p<0.0001), 이론실습연계성(r=0.216 0.0097)이 높을수록 상관성을 보였다, 만족도, 전공연계성의 유용성, 혼합강의의 유용성, 이론실습연계성에서는 학업성취도를 제외한 모든 요소에서, 흥미도는 난이도와 학업성취도를 제외한 모든 요소에서 유의성 있게 높은 상관성을 보였다. 하지만 학업성취도에서는 평가의 적절성을 제외한 다른 요소에서는 연관성을 보이지 않아 성적과 관련해 영향을 미치는 요소가 없다는 것으로 판단되어지며 본 연구를 위해 도입된 강의구성이 해부학의 균형 있는 학업성취를 유도할 수 있는 수업방식이라 판단되었다. 결론적으로 본 연구를 통해 해부학강의에 있어 혼합강의의 우수한 교육효과를 알 수 있었고, 간호학과만이 아닌 최근 급증하고 있는 의료-보건계열의 다양한 전공자를 위한 적용, 확대로 해부학지식의 질적 향상과 강의수요에 비해 부족한 해부학 전공 교수진들의 교육 부담을 경감할 수 있는 효과적인 교수법으로 활용가치가 있다고 사료된다.

The purpose of this study was to investigate ways to improve the effect of English-medium instruction (EMI) in Korean universities by comparing EMI lectures in two Korean universities with those in a Japanese university. Some universities run all courses in English while others do so for only part of them. This study comparatively investigated how EMI courses were run by these two groups of universities. For the purpose of this study, in-depth interviews were conducted with EMI instructors and students to find out what merits and problems that such EMI programs had in EFL environment of Korea and Japan. Another important goal was to correct problems and improve the Korean programs. The result showed that the most important issue of EMI programs in Korean universities was students' low English proficiency. It also demonstrated that English for Academic Purposes (EAP) was necessary to overcome this problem. It is a key to the success of MI programs. Hopefully, this study will stimulate continuous discussions on limitations and ways to improve EMI in Korean universities in various aspects.

The purpose of this study is to analyze the perception of non-face-to-face online undergraduate lectures experienced by foreign learners, to identify problems of online lectures, and to suggest improvements. For this study, the perception of online lectures was investigated and analyzed by foreign undergraduate students who took online lectures at A and B universities. Through this, I explored the design direction, complementary measures, and direction of online lectures to be held at Korean universities in the future. As a result of this study, non-real-time lectures through E campus were recognized as advantages in that they could learn repeatedly and listen to lectures at home., Real-time lectures using Zoom were recognized as an advantage of being able to communicate between professors and learners. Both types of online lectures had many tasks and had difficulty in focusing on the lecture until the end. In the future, it was found that the amount of lecture contents and the amount of tasks should be reduced and the condition and sound quality of the lecture image should be improved. As for the evaluation method, they preferred online evaluation rather than offline evaluation, and they preferred relative evaluation rather than absolute evaluation. The results of this study were able to closely understand how learners perceive online lectures. Also, when conducting online lectures, I was able to know the points that need to be improved in the future. The results of this study are expected to contribute to the design direction of online lectures and the development of online contents at each university.

The purpose of this study was to evaluate the efficacy of basic integrative lecture course of medical college through cyber lecture. This study was also aimed to develop and implement a progressive cyber-teaching method which integrative lecture system is concerned for medical students. In this study, effectiveness of cyber lecture on the student's satisfaction, content difficulty and course management were analyzed by way of anonymous survey at the end of basic neuroscience integrative lecture course. Survey data were also analyzed with statistical tools to find out strength of correlation between students degree of satisfaction to cyber lecture and their individual grade of this course. The majority of students held positive opinions on course management, level of difficulty in each session, utilizing multimedia contents and preferred cyber lecture system to be continued in the future. Many students also suggested intimate integration of multimedia contents shown in cyber lecture to the lab sessions for the maximization of educational effect. In this study, it suggested that cyber lecture could be a useful tool in teaching integrative medical subjects and play more important role in the future integrative medical subjects with the improvement of present problems and limitations.

The purpose of this study was to investigate and analyze the operating conditions of lecture contents in contactless online classes for University students. First, as a result of analyzing the responses of 93 respondents, 93.3% of the respondents took real-time online lectures (47.7%) or recorded video lectures (45.6%). Second, as a result of analyzing the contents used as textbooks, it was found that e-books (materials) and paper books (materials) were used together (36.6%), or e-books or electronic materials (36.6% and 37.6% respectively) were used in both liberal arts (47.3%) and major subjects (39.8%). In addition to textbooks, both major subjects and liberal arts highly used web materials (47.6% and 40.5% respectively) and YouTube materials (33.3% and 48.0% respectively) as external materials. Third, both liberal arts and major subjects used 'electronic files in the form of PPT or text organized and written by instructors' (62.9% and 58.1% respectively), 'internet materials' (16.7% and 19% respectively) and 'paper book or materials' (10.4% and 12.3% respectively) to share lecture contents. For the screen displayed lecture contents, 93.5% of the respondents satisfied in major subjects, and 90.2% of the respondents satisfied in liberal arts. These results suggest developing multimedia-based lecture contents and an evaluation solution capable of real-time exam supervision, developing a task management system capable of AI-based plagiarism search, task guidance, and task evaluation, and institutionalizing a solution to copyright problems for electronicizing lecture materials so that lectures can be given in the ubiquitous environment.

남강은 낙동강 유역의 중하류에 위치하고 있으며, 낙동강에 우안으로 합류되는 제 1지류이다. 낙동강 본류 하천의 지류하천이지만 국가하천이며, 비교적 큰 유량을 가지고 있다. 낙동강은 본류를 취수원을 이용하고 있어, 남강과 같이 지류 하천유입 이후의 낙동강 본류에 거동이 중요하다. 취수 원수는 정수처리과정에서도 우선적으로 고려해야 하는 인자이다. 따라서 남강이 합류되는 합류에서의 혼합거동은 중요하다. 혼합거동을 보고자 추적자 실험을 수행하였다. 추적자 실험은 공간적으로는 남강과 낙동강의 합류점 부근을 선택하였고, 시간적으로는 계절별, 보 운영 시기별로 실험하였다. 또한 합류부 주변에서의 유량측정과 자연추적자의 농도 측정으로 수행하였다. 낙동강과 남강은 대하천이므로 유량측정을 ADCP(Acoustic Doppler current profiler)을 활용하였으며, 추적자의 농도 추적은 센서를 통해 현장 측정하였다. 또한 영상분석을 하고자 드론도 활용하였다. 추적자 실험 분석을 유량과 추적자 농도 분산 정도를 분석하였다. 이를 활용하여 지류하천인 남강의 합류이후 낙동강 본류의 거동을 분석하였다. 분석한 결과를 바탕으로 남강의 유량시기별 혼합거동은 달라지는 것으로 나타났다. 또한 드론을 활용한 분석도 혼합거동에서 적용할 수 있을 것으로 판단된다. 추적자 실험을 통해 취수 원수의 특성을 분석할 수 있었다. 향후 유량 변화의 따른 남강합류후 낙동강의 혼합거동의 기초자료 자료 활용 될 것으로 판단된다. 또한 취수원수의 특성을 위한 유량별 다기능보 운영 시기별 혼합거동 분석을 위한 추가 실험이 필요할 것 판단된다.
