The teaching of manufacturing technology has been researched according to the situation of independent college. That be strict with students and concise key contents could bring good effect in class. Mechanical processing video can add engineering background .Reform the examination can reduce examination malpractice, can promote the ability of operation, and can deepen the understanding of the text. The network technology does help to teach and communicate conveniently. Encourage students to participate professional contest brings professional atmosphere. The teaching mode cultivates the students’ independent thinking and practical ability. The effects play a good foundation for professional study.

Undergraduates, generally 18-24 years old, are in the most active period of sexual lives. With the development of economy and Internet, students have more ways to access to sexual information, some of which are wrong. To characterize the differences and similarities among college students about their contraceptive knowledge and attitude towards sex education,anonymous questionnaire forms were sent out to undergraduates from college of Liberal arts, Yunnan University. With the help of SO JUMP, the overall sample was randomly chosen and consisted of four grades in undergraduates. In order to analyze the gender differences in the research topics, the respondents were divided into two groups based on gender. Last, three conclusions were drawn:firstly, misleading knowledge of contraception was found in undergraduates; next, males have better contraceptive knowledge than female students; finally, not only should universities and colleges spread correct reproductive knowledge among students, but also society as a whole should popularize safe sexual practices.

With the continuing development of China＇ s college Public arts Education, a good foundation has been laid for China＇ s arts education. However, drastic changes have been taken place in modem teaching values, and the college curriculum system of Public arts Education failed to meet the needs of development, thus, to optimize the college curriculum system of Public arts Education has become a tough task in the field of education. This paper is going to make an analysis of Curriculum System Reform of Public arts Education in three aspects.

Background: In the Kingdom of Saudi Arabia (KSA), recent studies revealed increasing consumption of animal products and refined foods in the diet at the expense of vegetables and fruits. These dietary changes were accused of increasing the prevalence of both overweight and obesity observed among Saudi children, adolescences and adults in the last few decades. Objectives: The present study was a cross sectional study aimed at exploring the BMI distribution among students of college of Sciences and arts for girls Khamis Mushayt Campus 1 at King Khalid University (KKU) and investigated how Dietary habits of students female affected body mass index (BMI). Methods: A total of 240 female students aged 18 - 22 years were about 25% from total students randomly chosen from college of arts and Science Campus 1 at Khamis Mushayt, King Khalid University, KSA for the present study. A self-reported questionnaire about the student’s dietary habits was conducted and their body mass index (BMI) was measured. Data were analyzed using SPSS statistical software and Chi-square test conducted for variables. Results: About half of the students (47%) were within normal weight, 27.4% were under weight, 16% were overweight and 9.6% were categorized obese. The majority of the students reported eating meals with their family while more than half of sample (58.7%) had eating meals during watching TV. It was worth mentioning that 84.5% of students reported eating snacks such as chocolate and chips 3 or more times per week. There were no significant differences between BMI category and dietary habits. Conclusion and Recommendations: There were no significant difference between body mass index category and dietary habits. Increasing educational programs introduced healthy dietary concepts to improve the dietary habits of female students.

The dynamics of spin–orbit-coupled Bose–Einstein condensate with parity-time symmetry through a moving obstacle potential is simulated numerically. In the miscible two-component condensate, the formation of the Kármán vortex street is observed in one component, while ‘the half-quantum vortex street' is observed in the other component. Other patterns of vortex shedding, such as oblique vortex dipoles, V-shaped vortex pairs, irregular turbulence, and combined modes of various wakes, can also be found. The ratio of inter-vortex spacing in one row to the distance between vortex rows is approximately0.18, which is less than the stability condition 0.28 of classical fluid. The drag force acting on the obstacle potential is simulated. The parametric regions of Kármán vortex street and other vortex patterns are calculated. The range of Kármán vortex street is surrounded by the region of combined modes. In addition, spin–orbit coupling disrupts the symmetry of the system and the gain-loss affects the local particle distribution of the system, which leads to the local symmetry breaking of the system, and finally influences the stability of the Kármán vortex street. Finally, we propose an experimental protocol to realize the Kármán vortex street in a system.
