  • 이 연구의 목적은 로봇교육 특히, 로봇교육 캠프에서 보조교사가 학습자를 지원하는 유형에 따라서 학습자들의 창의성과 자기효능감에 어떤 변화가 있는지 확인하는 것이다. 연구의 대상은 캠프 참가자 초등학생 72명을 9명씩 1모둠으로 총 8모둠을 구성하여, 이중 4모둠은 보조교사가 공동 참여, 나머지 4모둠은 필요한 정보나 질문에 대한 피드백을 제공하는 형태로 지원하도록 하였다. 연구의 목적을 달성하기 위해 가설은 보조교사가 학생들의 로봇 제작과 프로그래밍 활동에 지원하는 형태에 따라 학습자의 창의성과 자기효능감에는 유의미한 차이가 없을 것이다로 설정하였다. 이와 같은 가설을 검증하기 위하여 이질 통제 집단 전후 검사 설계 방식을 적용하였다. 연구의 결과는 다음과 같다. 보조교사 지원 유형에 따라 학습자의 창의성은 유의미한 차이가 없었으나, 자기효능감에서는 보조교사가 공동으로 참여한 학생 집단보다 보조교사가 학습자들이 필요한 정보나 질문에 피드백을 제공하는 지원 형태의 학생 집단이 자기효능감에서 높은 성취를 보였다. 이 결과는 보조교사가 직접적으로 학습자들을 도와줄 경우 학습자들은 보조교사에게 의존하여 학습의 과정에서 자기주도성 및 통제감이 떨어지기 때문으로 사료되며, 이 점은 향후 로봇교육에서 보조교사의 지원유형에 관한 후속 연구에 시사점을 제공하리라 판단된다.

  • Objectives : I analysed daehwangmokdan-tang's compatibility principle by the system of chief, deputy, assistant, and envoy and investigated pharmacological activities by categorizing with chemical components, molecular level, cellular level, animal level and human level based on Korean and Chinese studies for this formula. Methods : Daehwangmokdan-tang's compatibiltity principle was examined by the system of chief, deputy, assistant, and envoy. I looked into studies that presented in Korea from 1956 to 2016 about daehwangmokdan-tang through KOREA INSTITUTE OF ORIENTAL MEDICINE, Korean medicine information system (OASIS) and in Chinese for 20 years about daehwangmokdan-tang through China National Knowledge Infrastructure, CNKI. Then classify into chemical components, molecular level, cellular level, animal level and human level to analyse. Results : According to the system of chief, deputy, assistant, and envoy, chief herb is Rhei Radix et Rhizoma and Moutan Cortex, deputy herb is Natrii Sulfas and Persicae Semen, assistant and envoy herbs are Trichosanthis Semen. The amount of extraction of paeonol, total anthraquinone, and conjugated anthraquinone from daehwangmokdan-tang with the formulation of the system of chief, deputy, assistant, and envoy was the highest, and in the formulation of chief herb and deputy herb, the extraction amount of paeonol and conjugated anthraquinone was the lowest. With other formulations, the amount of extraction of total anthraquinone and conjugated anthraquinone was improved, although the degree was different. In particular, when it is blended with Persicae Semen as a deputy herb, the extraction amount of total anthraquinone and conjugated anthraquinone of Rhei Radix et Rhizoma as a chief herb is greatly increased, and the extraction amount of paeonol is rather different, but it is lowered. It was found that the amount of Mg Ca K Na in daehwangmokdan-tang was the highest. Pharmacological activities can be detected in inflammatory mediators and enzymes for molecular level. For cellular level, it can be determined in lipopolysaccharide (LPS)-stimulated RAW 264.7 cell line. In mouse and rats for animal level and human level, in inflammatory diseases (acute appendicitis, acute pancreatitis, acute cholecystitis, acute abdominal disease, ect.), pharmacological activities was caught. Conclusions : From the above results, daehwangmokdan-tang is composed in line with the system of chief, deputy, assistant, and envoy, suggesting that there is certain rationality and scientific. Pharmacological activities of daehwangmokdan-tang are effective to anti-inflammation, improvement of sepsis, analgesic, muscle relaxation, and improvement of intestinal flora and its metabolites. Daehwangmokdan-tang is consistent with the action of diuresis and anti-inflammation in terms of the content of elements, suggesting that there is action of purging fire and removing blood stasis, defecation detoxification, cooling blood and clearing heat and activating blood and dispersing stasis.

  • 본 논문에서는 컴퓨터 비전을 이용한 강의 도우미 시스템을 제안한다. 강의자가 강의를 진행하며 사용하는 강의 노트 및 관련 동영상 등 다양한 강의 컨텐츠를 사용할 때, 컨텐츠 전환 등 컴퓨터 조작으로 인해 강의의 끊김이 유발된다. 제안하는 시스템에서는 강의 도중 강의 컴퓨터에 대한 조작이 필요할 때, 보드에 미리 정해진 기호를 그려 넣고 시스템이 이를 인식하여 해당 조작을 수행함으로써 강의 끊김 없이 손쉽게 강의를 이끌어 가도록 도와준다. 제안된 강의 도우미 시스템에서는 임의의 기호를 인식하기 위해 모양 문맥이라는 특징 표현자를 사용한다.

  • Science festivals have occupied a very important axle in informal science education that enables students to experience the amazement of scientific experiments to think over scientific principals beyond the formal education in the classrooms. Among the concerned person, the most benefit-taken group may be the assistant who help the participants experience the activities in the festival. In order to find out the ways to make the student assistant's participation into a meaningful education experience, we analyzed the types of the activities in the science festival as well as the characteristics of the interaction between the student-assistants and the participating students are studied. The research findings are as follows: First, most activities in the science festival had related to the scientific concepts or principals; however, the understanding of the concepts and principals didn't highly affect the procedure of the activities. In many cases the students operated and made results without checking the related concepts or principals. Second, the student-assistants showed the consistency of operation in guiding their activities. They were explaining mainly the process of the experiments without giving a chance to think of related concepts or principles. We suggest that teacher should consider the student-assistants' learning in the festival as well as that of the participants.

  • In this paper, we deal with the static modeling of a continuum robot that can perform surgical interventions. The proposed continuum robot is made of stainless steel wires and a multi lumen flexible tube using a thermoplastic elastomer. This continuum robot could be most severely deformed in physical contact with narrow external environments, when a lateral external force acts at the distal tip of the continuum robot. In order to predict the shape and displacement under the lateral external force loading, the forward kinematics, the statics modeling, the force-moment equilibrium equation, and the virtual work-energy method of the continuum robot are described. The deflection displacements were calculated using the virtual work-energy method, and the results were compared with the displacement obtained by the conventional cantilever beam theories. In conclusion, the proposed static modeling and the virtual work-energy method can be used in arrhythmia procedure simulations.

  • Purpose: This is a mixed method study to understand the experience regarding the job satisfaction of Physician Assistant (PA) male nurses. Methods: First, factors influencing job satisfaction were analyzed using quantitative approach and job adaptation processes by qualitative research was done through interviews. Finally both of the collected data were comprehensively compared. Results: The factors which had the greatest influence on job satisfaction in the regression analysis were job stress (${\beta}=-.49$, p<.001) and job identity (${\beta}=.46$, p<.001) and the explanatory power explaining these variables was 58% (Adj. $R^2=.58$). The results of qualitative research were categorized using the same four variables with qualitative research variables. Five themes in job satisfaction, three themes in job identity, five themes in job stress and six themes in job value were identified by content analysis. Conclusion: This finding identified that the job stress and job identity were important variables related to job satisfaction. Therefore, the factors influencing job identity have to be strengthened, and a systematic management and interest to develop them are necessary.
