This study investigated whether a real-time video lecture using the Learner Response System has a positive effect on the student satisfaction with a video-based online TOEIC course when the real-time video lectures are additionally provided to the students. It was also investigated whether the convenience of an online course such as taking a course at students pace at the time and place they want would have any influence on the student satisfaction with the online course. 287 college students took the online TOEIC course during the fall semester of 2020 from September through December and at the end of the course, they were given a survey asking their opinions on the effects of the Learner Response System used in the real-time video lecture and on the convenience of online course. The analysis of the survey showed that the Learner Response System used in the real-time video lecture had a significant positive effect on the student satisfaction, but that there was no significant correlation of the convenience of the online lecture with the student satisfaction. The results of this study suggest that if it is effectively used in the real-time video lectures, the Learner Response System can enhance the teacher-student communication and student satisfaction with a video-based online course.

박성배(Park, SungBae),오규환(Oh, GyuHwan) 한국게임학회 2013 한국게임학회 논문지 Vol.13 No.4

본 논문에서는 스마트기기에 적합한 실시간 번개 시뮬레이션을 제시한다. 물리학에 기반을 가지는 Dielectric Breakdown Model을 근사하여 스마트기기 환경에서 실시간 구현이 가능한 번개 경로 결정 알고리즘을 제시하며, 여러 개의 번개를 동시에 그리고 실시간으로 렌더링 할 수 있는 방법을 제시한다. 마지막으로 번개의 경로를 실시간으로 수정할 수 있는 방법을 제시하여 유저와 실시간 상호작용이 가능하게 한다. 본 논문에서 제시한 번개 시뮬레이션은 스마트기기 환경에서 번개가 주 요소인 게임에서 사용이 될 것으로 판단된다. In this paper, we show a real-time lightning simulation for smart device game. Our proposed method uses physically based Dielectric Breakdown Model to similar real world lightning path and we simplify the algorithm for real-time simulation in smart device. In addition, the rendering process can render multiple lightning and can real-time render in smart device. Finally, our lightning can support interactive with user. The simulation method will be effectively useful for a game that needs a real-time simulation as its game element in smart device environment.

박성배 ( Sungbae Park ),양덕순 ( Duksoon Yang ),김명상 ( Myungsang Kim ) 사단법인 아시아문화학술원 2020 인문사회 21 Vol.11 No.6

본 연구는 ‘제주 지방자치’ 관련 연구들의 주제어를 분석하여 연구동향을 파악하고 시사점을 도출하여 관련 연구의 방향성을 제시하는데 그 목적이 있다. 이를 위해 제주특별자치도 출범 이후 발표된 196편의 등재후보지 이상의 학술지를 네트워크 분석을 통해 분석하였다. 분석결과 제주특별자치도-자치경찰-지방자치-지방분권 등의 주요 연결단어들이 1~3기에 모두 고르게 나타났으나 출현 빈도가 적은 주제어를 통해 다양한 분야에서 연구가 진행됨을 알 수 있었으며, 자치경찰은 전국적인 도입을 앞두고 제주가 제도적으로 선도적인 역할을 수행함을 알 수 있었다. 다만 국제자유도시와 특별자치도 완성을 위한 좀 더 다양한 논의와 연구의 시도가 필요하며 네트워크 분석의 다양한 방법을 충분히 활용하지 못한 점을 한계로 볼 수 있다. The purpose of this study is to analyze the main words of the studies related to ‘Jeju local autonomy’ to identify research trends and to draw suggestions and present the direction of related research. For this purpose, 196 academic journals published after the establishment of the Jeju special self-governing province were analyzed through network analysis. According to the analysis, major connected words such as Jeju special self-governing province, self-governing police, local autonomy, and decentralization were found to be evenly distributed in the first to third periods, but research was conducted in various fields through subject words that appeared less frequently, and the local police showed that Jeju played a leading role in the system ahead of the nationwide introduction. However, the limitation is that more diverse discussions and research attempts are needed to complete the international free city and special autonomous islands, and that various methods of network analysis have not been fully utilized.

박성배(Sungbae Park) 한국영미어문학회 2023 영미어문학 Vol.- No.148

이 연구는 온라인 실시간 강의 진행에 메타버스 플랫폼 게더타운과 화상회의 플랫폼 줌이 사용되었을 때 어떤 플랫폼이 학습자의 수업 성취도에 긍정적인 영향을 주는지, 학습자가 해당 플랫폼에 느끼는 만족도에 차이가 있는지를 조사하였다. 138명의 대학생이 2021년 2학기에 5회의 온라인 실시간 수업을 받았다. 학생들은 게더타운그룹과 줌그룹으로 나누어졌다. 수업 성취도를 조사하기 위하여 각 그룹은 수업 기간 동안 단어시험과 학습 퀴즈에 응시하였다. 단어 시험과 학습 퀴즈는 게더타운그룹의 성적이 줌그룹보다 유의하게 높았다. 또한 학습자가 각 플랫폼에 대하여 느낀 만족도를 조사하기 위하여 설문 조사를 하였다. 설문 결과 게더타운그룹은 수업에 대한 학습자의 흥미와 상호 작용을 촉진 시키는 것을 게더타운의 장점으로, 접속상의 문제를 단점으로 언급했다. 줌그룹은 편의성을 줌의 장점으로, 수업집중도 저하를 줌의 단점으로 언급했다. This study investigated which platform had a more positive effect on the learners' class achievement when the metaverse platform Gather Town and the video conference platform Zoom were used for online real - time lectures, and whether there was a difference in the degree of the learners' satisfaction with each platform. One hundred and thirty eight college students took a five - session online real - time class during the fall semester of 2021. The students were divided into the Gather Town group and the Zoom group. To investigate the class achievement, each group took a vocabulary test and a comprehension quiz during the class. The scores of the Gather Town group were significantly higher than those of the Zoom group in the test and quiz. In addition, a survey was conducted to investigate the learners' satisfaction with each platform. The Gather Town group cited promoting students' interest in class and interaction as the merit of the platform, and connection problems as the demerit. The Zoom group cited convenience as the merit of the platform, and a decrease in class concentration as the demerit.

This study examined the influence of three types of presence(teaching, cognitive, and emotional presence) and that of four online teaching tools(real-time video lecture, pre-recorded lecture, Naver Band, Google Form) on the lecture satisfaction in an online non-face-to-face TOEIC class. In addition, the learners’ perception on the online class was analyzed. 298 university students who were the participants of this study took beginner level online TOEIC classes in the first semester of 2020 and were surveyed at the end of the semester to analyze the influence of the three types of presence and four online teaching tools. The findings showed that the three types of presence had significant influence on the lecture satisfaction and that the four online teaching tools had significant influence on the lecture satisfaction. Learners perceived the flexibility in choosing a time and place and repeated viewing of the lecture at their pace as advantages of the online class. They perceived the internet connection problems and the difficulty in maintaining concentration as disadvantages.

다바바타르어뜨게렐 ( Davaabaatar Odgerel ),박성배 ( Sungbae Park ),양덕순 ( Duksoon Yang ) 사단법인 아시아문화학술원 2021 인문사회 21 Vol.12 No.3

본 연구는 몽골과 제주특별자치도의 주민참여예산제도 비교분석을 통해 몽골의 주민참여예산제도 발전 방안을 모색하는데 목적이 있다. 이를 위해 기존 발표된 문헌, 학술지, 학위논문, 웹사이트 등을 통해 자료를 분석하였다. 주민참여예산제도와 관련하여 몽골은 법령이 존재하나 세부 제도, 조례에 대한 준비가 필요하며, 주민참여 활성화를 위한 참여예산 기구 확대, 정보공개, 다양한 홍보방안 등이 필요하다. 다만 양 지역 간 상이한 운영제도, 규모의 차이, 언어의 차이, 기존 선행연구 부족 등이 연구의 한계이며 후속 연구에는 다양한 비교구성과 연구방법 등을 통해 이를 보완해 나갈 필요가 있다. This study aims to find ways to develop Mongolia’s resident participation budget system through a comparative analysis of the residents’ participation budget system in Mongolia and Jeju Special Self-Governing Province. To this end, data were analyzed through existing published literature, academic journals, dissertations, and websites. In relation to the residents’ participation budget system, Mongolia has laws and regulations, but preparations for detailed systems and ordinances are needed, It is necessary to expand participatory budget organizations, disclose information, and various promotional measures to promote residents’ participation. However, different operating systems, size differences, language differences, and lack of existing prior research between the two regions are limitations of research, and follow-up research needs to be supplemented by various comparative composition and research methods.

Large number of part design such as for aircraft and automotive development is preceded by functional or sectional design groups for efficiency. With the assembly development of large number of parts, interferences and gaps can be found when the parts and sub-assemblies by those design groups are to be assembled. When rainwater come into the space among parts and is not be drained sufficiently, rainwater within the structure can backflow to gaps or unexpected outlets, which may cause severe problems of part corrosion and electric shock. This research has developed a method and a program to simulate backflow of rainwater within space among parts, which can find unexpected outlets and gaps as in real situation. The developed program can not only simulate up and downstream of liquid, but also the flow with multiple channels of division and joining. The developed method can also be applied to aircraft and ship design process.

Large number of part design for aircraft and automobile is preceded by functional or sectional design groups for efficiency. However, interferences and gaps can be found when the parts and sub-assemblies by those design groups are to be assembled. These interferences and gaps cause design changes and additional repair processes. While interference problem has been resolved by digital mockup and concurrent engineering methodology, gap problem has been covered by temporary treatment of filling gap with sealant. This kind of fast fix causes fatal problem of leakage when the gap is too big for filling or the treatment gets old. With this research, we have developed a program to find the gap automatically among parts of assembly so that users can find them to correct their design before manufacturing stage. By using decomposition model representation method, the developed program can search the gap among complex car body parts to be visualized with volumetric information. It can also define the boundary between the gap and exterior empty space automatically. Though we have proved the efficiency of the developed program by applying to automobile assembly, application of the program is not limited to car body only, but also can be extended to aircraft and ship design of large number of parts.
