ABSTRACT
Poor experience of teacher-student interaction and low user loyalty exist in MOOC (massive open online courses).Therefore,the campus open online courses (COOC),a network teaching platform,was developed to integrate traditional classroom teaching and network teaching and to build an online-offline curriculum system according to professional training scheme of school.The online-offline teaching design and learning evaluation in COOC platform was also developed.The running data of COOC platform showed that the online-offline learning evaluation model has guiding impact on students' learning attitude because it can record the students' learning process and learning effect,which can enhance students' active participation in self-directed learning.The learning evaluation model in COOC is objective and scientific,which is helpful to improve the quality of teaching and learning.
ABSTRACT
Skin aging principles play important roles in skin disease diagnosis, the evaluation of skin cosmetic effect, forensic identification and age identification in sports competition, etc. This paper proposes a new method to evaluate the skin aging objectively and quantitatively by skin texture area. Firstly, the enlarged skin image was acquired. Then, the skin texture image was segmented by using the iterative threshold method, and the skin ridge image was extracted according to the watershed algorithm. Finally, the skin ridge areas of the skin texture were extracted. The experiment data showed that the average areas of skin ridges, of both men and women, had a good correlation with age (the correlation coefficient r of male was 0.938, and the correlation coefficient r of female was 0.922), and skin texture area and age regression curve showed that the skin texture area increased with age. Therefore, it is effective to evaluate skin aging objectively by the new method presented in this paper.

Computer science is not important enough in the medical university curriculum and students do not like this course. Therefore, game-teaching methods were employed to enrich teaching methods,to make medical teaching more vivid and to promote medical students' learning interests. In this paper,application of game-learning idea in the medical teaching process was discussed from multiple aspects including the story of the game,incentives of the game and the punitive measures of the game.
ABSTRACT
Computer laboratory teaching is the most important method to train the computer operating skills of medical students.Therefore,we have attempted the student-centered open-laboratory teaching model.This teaching model can train the computer operating skills and creative ability of students in medical college.
ABSTRACT
Objective:The legal medical experts usuallycalculate the area ofinjured organs in bodyor other injured items bycountingthe grids in coordination paper.The experiences of the legal medical experts determine the result of this method.The result is subjective and has serious errors.So it is not conductive to the court and case detection.Methods:This paper proposes a method to calculate the injured area by hybrid of K-means algorithm and region growing algorithm.Results:The experiment shows this method is effective to calculate the area of irregular region.Conclusion:The result of this method is more accurate than the method of counting the grids in coordination paper.
