In recent years, professionalism education has been incorporated into medical education as an important part of the curriculum. Through receiving professionalism education, most medical students gradually acquire professionalism, including a professional attitude. However, some medical students demonstrate unprofessional behavior that raises concerns among faculty and other students. There are various stages to dealing with unprofessional behavior, as follows: definition, prevention, detection, evaluation, correction, and follow-up. However, it is often difficult to identify unprofessional behavior and respond appropriately. In this study, overview of medical students’ unprofessional behavior from previous studies on medical students’ unprofessionalism behavior, and how to identify and evaluate medical students’ unprofessional behavior, and effective education that can correct medical students’ unprofessional behavior was analyzed by reviewing 52 articles. Medical students’ unprofessional behavior is classified into the following four categories: “lack of involvement,” “lack of integrity,” “lack of interaction,” and “lack of introspection.” The occurrence of unprofessional behavior was found to be attributed to personal problems, interpersonal problems, external factors, and environmental factors. Educators analyzed unprofessional behavior and its causes from four categories. Medical students should perform reflective writing to help them reflect on their unprofessional behavior. Educators should use this reflective writing to interact with medical students, and to investigate and analyze the students’ unprofessional behavior. Furthermore, educators will need to assess unprofessional behavior using a roadmap to address unprofessionalism, and to respond appropriately to each stage of the roadmap. Individualized educational interventions should be provided to help students correct their unprofessional behavior.

Purpose
This study aimed to clarify the attitudes, behaviors, and learning experiences of first-year medical students participating in a nursing practice training aimed at enhancing their professionalism.
Methods
A questionnaire survey was conducted among first-year medical students after their nursing practical training to understand their learning experiences. Descriptive statistics was performed for each questionnaire item. For free-text responses, descriptions were grouped by input data with similar content and meaning, and analyzed qualitatively. Others’ evaluation and self-evaluation were analyzed quantitatively.
Results
Most students were actively engaged and fulfilled in the training. The free comments generated these categories: “nursing care,” “roles of nurses,” “patient impressions,” “multidisciplinary cooperation,” “communication,” and “what is required of physicians. On the first day, all items evaluated had higher mean scores in the others’ evaluation than in the self-evaluation. On the second day, for “maintains standards of personal appearance (including uniform, hair, and name tag),” the others’ evaluation means were higher than the self-evaluation means. T-tests showed a significant difference in “maintains standards of personal appearance (including uniform, hair, and name tag)” (t=-2.103, degrees of freedom [df]=71.104, p<0.05) and “attends to patients with a polite manner” (t=-2.087, df=74, p<0.05) for both the high and low groups.
Conclusion
Greeting, appearance, communication skills, and attitude were found to be the important bases of attitude education in the nursing training ideally involving multidisciplinary professionals. The medical students were able to grasp what is required of doctors and objectively view such position from the viewpoints of nurses and patients.
