Objective To study the risk factors of Pseudomonas aeruginosa (PA)infection and homology of PA isolated from nasopharyngeal carcinoma patients undergoing radiotherapy,and prevent and control the spread of in-fection.Methods Bacteria isolated from clinical specimens were identified by BD Phoenix automated microbiology system. Gene homology were analyzed with randomly amplified polymorphic DNA (RAPD)technique.Results Forty-nine strains of PA were mainly isolated from 43 nasopharyngeal carcinoma patients,the major specimens were nasopharyngeal swab (46.94% ),sputum(32.65% ),and oral secretion (10.20% ).All these strains were amplified 46 electrophore-sis diagrams,and 19 genotypes were identified. The highly homologous genotypes of type H and J strains were mainly isolated from patients in the second section (57.14% ,4/7)and fourth section (60.00% ,3/5)of radiotherapy department respectively. Conclusion Localized epidemic of highly homologous PA exists in different sections of ward,transfer of patients between different sections is the risk factor for homology PA infection/colonization. Gen-otyping technique such as RAPD for analyzing the homology of pathogenic bacteria in healthcare-associated infection has important value in preventing and control Ling infection spread.

The major satisfaction of college students will influence their learning interest and motivation, and then influence their learning achievement and future employment. Under the guidance of the concept of the micro system engineering of the education reform, the degree of the major satis-faction of the students in TCM colleges is analyzed by SIMPP method. The results show that students' behavior mode such as their preview situation, teaching adaptation, course satisfaction, students' achievement and their attitude of poor academic performance is closely related to the degree of major satisfaction. Teachers can judge the degree of major satisfaction by following these pattern behaviors;improve the rationality and accuracy of the degree of major satisfaction.

The degree of satisfaction of the curriculum is related not only to the degree of the curriculum but also to the degree of the students' development. With the concept of teaching reform micro system engineering, using the SIMPP analysis of the degree of satisfaction of the curriculum, the relevant factors of the students are studied. The results show that, the learning state, learning objec-tives, and the education level of mother affect the students more easily on the curriculum satisfaction. Research shows, in the present curriculum condition, educators should guide the students to study hard, establish a clear and reasonable learning goal, give the students the introduction and analysis of the curriculum, can effectively improve the students on the curriculum satisfaction, enhance the enthusiasm of the study.

In recent years, lower and lower class attendance has plagued the quality of uni-versity teaching. To solve this problem, this study conducted a questionnaire survey in accordance with the concepts of the Education Reform microscopic systems engineering and the method of SIMPP. The results showed that factors affecting student classroom attendance included two aspects: the sub-jective and objective factors. Indicators related to the subjective factors were: the personal attitude when faced with failure exams, the personal learning interest and personal grasp of the main source of knowledge. Indicators related to the objective factors were: school and teachers. Also, this study gave some suggestions on how to improve students' classroom attendance to provide data basis and refer-ence for further study on class attendance.

According to the theory of microscopic system reform in higher education, a total of 927 college students of different majors from Beijing University of Chinese Medicine were investigated by using SIMPP method. It indicated that through promoting the study of self-prepared, learning state and learning effect, students can enhance their learning ability of the admission acceptance. From the perspective of teachers, the students' self-study ability can be fully mobilized using individual person-alized teaching method. Then, the initiative of university education in the teaching and learning can be improved. Ultimately, the efficiency of student learning can be improved.

College students' self cognition of the learning effectiveness influences their learning behavior greatly. Focusing on college students' self cognition of their learning effectiveness, and then standardizing their learning behavior is one of the important work of educators in colleges. Therefore this paper has designed the questionnaire of the influencing factors of learning effectiveness self cog-nition, used SIMPP analysis method to analyze it, and set up the relation model. The analysis shows that college students' self cognition of learning effectiveness is influenced not only by students' dili-gence level and the recognition degree of specialized subject, but also by the factors such as the attitude when you get the bad results. The result provides data basis and scientific basis for future practice and relevant research for educators in colleges.

Academic diligence level can not only directly affect the academic performance of students, but also affect the individual's emotional and physical health. In this study, through a question-naire survey of university students, with the method of SIMPP and the concept of the micro system engi-neering in higher education teaching reform, the related factors of diligence and the college students' behavior mode with respect to diligence are systematically analyzed. Analysis shows that, students' diligence level is affected not only by inherent factors such as clear learning objectives, learning state and after-school learning time, but also by the school ethos, the influence factors of the curriculum and parents' re-quirements.

The clear learning objective is one of the important factors to determine the learning effect of college students. In order to analyze the factors affecting the formation process of college stu-dents' learning objectives, to explore the teaching mode that can be helpful for college students' clear learning objective, under the guidance of the concept of the reform of the teaching system, the SIMPP analysis of the students learning objective in the TCM colleges was carried out. Results showed that the related factors that affected student learning objectives included family factors, school principals and students' subjective factors. Teachers' observing students' learning status carefully, their understanding students' background, income and other social factors, mastering the degree of students' learning spe-cific goals and behavior model, and conducting the targeted and effective inventiveness are to help students clear learning objectives. The results provide the technology and method of operation for col-lege teachers to correctly guide different types of students to establish a clear learning objective.

The influence extent of students from teachers is related to the teaching effect , which means whether it can successfully promote the study of students and reach the expected teach-ing goal during the teaching process. To have a good teaching effect, guided by the micro-system en-gineering of teaching reform, we used SIMPP to analyze the related factors of the influence of students extent from teachers during the teaching process in TCM colleges and universities. The result shows that the influence extent from teachers is related to not only teachers themselves but students and their self-condition and family backgrounds as well. Going further in researching these factors and the related behavior patterns of influence extent of students from teachers is helpful to making the teach-ing more effective and more targeted.

Interest in learning can not only stimulate students' enthusiasm for learning, but also directly affect the quality of higher education. In this paper, the questionnaire of the related factors of college students' interest was designed to carry out micro-system engineering research. The factors as-sociated with college students' interest in learning and their complex relationships were investigated by using methods of systems science and systems engineering. The results shows that the students who can actively participate in after-school learning discussions , feel good in lectures and have clear learning objectives, are interested in learning. And at the same time, the teacher's influence and his active guidance in classroom teaching will raise students' interest in learning. This study provides a more comprehensive basis and clues to improve students' interest in learning and education reform.
