Among N. gonorrhoeae strains isolated in Nanjing, China, plasmid mediated resistance including PPNG and TRNG increased significantly between 1999 and 2006. Chromosomally mediated resistance to both penicillin and ciprofloxacin was also high during this period. Spectinomycin resistance of N. gonorrhoeae was sporadic. Ceftriaxone and spectinomycin can be considered effective antimicrobial agents for the treatment of gonorrhea in Nanjing at the present time.

The more and more developed network has caused more and more impact on people’s life and work, providing convenient channels for people’s information exchange, and then improving people’s living and working conditions. However, when data is transmitted through the network, there are hidden security risks, especially important accounting data. Once intercepted and used by criminals, it may cause serious harm to the owner of the data. Based on the above background, the purpose of this article is to study the use of the DES algorithm to encrypt accounting data in a computing environment. This paper proposes an improved quantum genetic algorithm and applies it to the S-box design of the DES algorithm, which improves the non-linearity of the S-box, reduces the differential uniformity, and enhances the security of the DES algorithm. This improved DES algorithm reduces the number of iterations by increasing the key length and iterative processing using a two-round function, which further increases the security of the algorithm and improves the operation speed of the encryption process. It is found that the 64 ciphertexts of the DES algorithm and the number of changed bits compared to the original ciphertext fluctuates around 32 bits, which explains the problems that should be paid attention to when using the DES algorithm to encrypt accounting data. The validity of key characters should be guaranteed to prevent key loss or leakage. Shorter data encryption regular solution.

Building on foreign literature about the attitude toward qualitative methods for psychology and combining with our local experience of teaching qualitative methods to psychology students, we revised and validated the original scale of Attitude towards Qualitative Research in Psychology (AQRP), generating Attitude Scale for Qualitative Research in Psychology (ASQRP). The scale was also applied to evaluate the effect of our course on qualitative methods for psychology. Three studies were conducted to explore, revise and validate the scale. In study 1, we translated and revised the original scale with eighteen items from the previous study. In a sample of 311 students enrolled in psychology courses, we surveyed and conducted a confirmatory factor analysis on four dimensions of the original scale. Among them, there was zero correlation between perceived lack of validity and qualitative orientation, while the two dimensions of the original scale were negatively correlated. The results of the fitness index were slightly away from expectations. In study 2, we added six locally adapted items to the scale and surveyed again to gain a sample of 249 psychology students. Exploratory analysis established a three-dimension structure of the Attitude Scale for Qualitative Research in Psychology (ASQPR) containing “perceived lack of validity,” “capturing the lived experience,” and “time- and resource- intensive,” with twenty-two items remaining and the dimension of “qualitative orientation” in the original scale reduced. Correlations between the ASQPR and Knowledge about Qualitative Research Scale and Psychology as a Science Scale showed acceptable validity. In study 3, the ASQPR was applied to assess students’ learning outcomes who took part in the psychological qualitative methods courses for a semester. We used a pretest-posttest design to track the attitude changes in three samples of students (179 in total). After the course, students increased their knowledge about qualitative research and realized the advantages of qualitative approach (i.e., capturing the lived experience) and quantitative approach. They also generally think of qualitative research as time and resource-demanding. However, the ingrained perception of qualitative research as lacking validity remained unchanged. In sum, the current study developed a tool suitable for Chinese students to assess their attitudes towards qualitative research, which can assist in curriculum reform and construction involving teaching qualitative methods.
