Gross anatomy, with cadaver laboratory dissection, is in a unique position to preside over a rich number of activities such as the team work, integrity, active learning, communication in the small group-all aspects of professional conduct. The purposes of this study are to investigate the correlation of professionalism with academic performance and the characteristics of groups of students in the performance variables. First-year Pusan National University School of Medicine students (n=108) from the Class of 2015 taking the gross anatomy course were required to do the self- and peer assessment about the professional behaviors of each of the six members of their dissecting group. The students were classified into one of four subgroups based on their deviation from the self- and peer assessment medians, such as high peer/high self (HP/HS), high peer/low self (HP/LS), low peer/high self (LP/ HS), low peer/low self (LP/LS). There were significant higher scores in the high peer groups (HP/HS, HP/LS) in comparison with low peer groups (LP/HS, LP/LS) in the academic performance of end-of-term (F=3.24), credit (F=3.54), pre-Lab (F=3.94), practical examination (F=3.60) scores. Significant correlations among academic performance variables were observed generally. There were some differences in the correlation in the practical examination and other variables. The relatively high correlation between practical examination and other variables is HP/HS, followed by LP/LS, LP/HS and then HP/LS. In conclusion, peer- and self assessment subgroups showed a significant differences in the academic performance. This assignment would be available to evaluate work habits of professionalism in the gross anatomy laboratory. It is suggested that HP/HS group was more adaptable in the contextual leaning the gross anatomy course.

This study aims to determine the effects of formaldehyde exposure on self-reported symptoms of respiratory-eye mucosa and integumentary system during anatomy practices among Korean medical students. Data were collected using the web-based survey. Study subjects in 1st and 2nd grade medical student, and having anatomy dissection in medical college and medical graduate school. A total of 463 students from the 14 medical college and medical graduate school participated in this study. The results show that 261 (56.4%) of the participants responded feeling discomfort above moderate at anatomy dissection. After anatomy dissection, 104 (43.2%) students responded aggravating the symptom allergic rhinitis, xerophthalmia and so on. 209 (95.0%) of them responded the new symptom’s appearance. In the result of multiple logistic regression, women (OR: 2.000, 95% CI: 1.169~3.421) and the students with feeling discomfort (OR: 3.190, 95% CI: 1.807~5.632) were more likely to increase the risk of pre-existing respiratory · eye mucosal system symptom’s aggravation than the counter parts. For pre-existing integumentary system symptom’s aggravation, risk is significantly higher in elder age group (OR: 2.612, 95% CI: 1.187~5.750) and with disapproval protective equipments (OR: 2.217, 1.006~4.885). In case of new symptom’s appearance, people with feeling discomfort above moderate (OR: 5.097, 95% CI: 1.075~24.160) in respiratory · eye mucosal system were more likely to increase the risk of new symptom’s appearance. And for integumentary system, risk was higher in people with feeling discomfort (OR: 1.921, 95% CI: 1.218~3.031), in woman (OR: 1.711, 1.090~2.686) and without enough protective equipments preparation (OR: 1.953, 1.189~3.210). This study confirms the protective equipments for minimizing exposure from chemicals for cytological fixation (e,g formaldehyde) is not worn enough and students in anatomy dissection experience discomfort and disease after anatomy dissection. Therefore, this study indicates that the safe guideline in anatomy dissection should be enhanced and institutional strategy to protect student’s right of health should be provided.

Although commercialization of mobile phones has raised much concerns about the effects of radiofrequency radiation on the human body, few experimental studies have been conducted on the effects of radiofrequency radiation on physiological homeostasis, immune and inflammatory responses. Therefore, we presently investigated the effect of 835 MHz radiofrequency radiation on spontaneous wheel exercise, hormone and cytokines levels in the plasm of mice. Mice were divided into 4 groups as control, exercise, radiofrequency radiation, radiofrequency radiation & exercise group. The body weight, corticosterone and blood cytokine levels were checked for 10 weeks. Followed by the exposure to radiofrequency radiation for 6 hours a day, the more increase in body weight was observed in the radiofrequency radiation & exercise group than in the spontaneous exercise group. When the amount of spontaneous exercise was measured for 10 weeks, the amount of exercise was increased in the both control and spontaneous exercise group, while the amount of exercise was decreased in the radiofrequency radiation group. To determine whether the homeostasis, immune and inflammatory responses are indirectly affected by radiofrequency radiation exposure, IL-1β, IL-6, IL-12 (p70), TNF-α, IFNγ, and GM-CSF were measured by ELISA kit, respectively. As a result, the blood levels of IL-6, IL-12 (p70) and TNF-α in the spontaneous exercise group were higher than that of control group, and each cytokine levels in the radiofrequency radiation & exercise group were lower than that of control group. However, the corticosterone, IL- 1β, IFNγ and GM-CSF didn’t show statistically significant differences in all groups. It has been confirmed that exposure to high frequency electromagnetic waves for a long time can affect the amount of exercise, body weight, and some inflammatory cytokines such as IL-6, IL-12 (p70) and TNF-α.
