  • Purpose: The aim of this study was to identify the level of Human papillomavirus (HPV) knowledge, intention of HPV vaccination, and barriers on HPV vaccination among male undergraduate students of Health department and Non-health department. Methods: A total of 149 male undergraduate students responded to self-administered questionnaires about their HPV knowledge, HPV vaccination intention, and their barriers on HPV vaccination. ANOVA, t-test and $x^2$ test (Fisher's exact test) were used for data analysis. Results: Mean score of HPV knowledge was $3.39{\pm}3.05$, and there was significant difference between Health department ($4.15{\pm}3.08$) and Non-health department ($2.58{\pm}2.82$) in HPV knowledge (t=3.241, p=.001). There was no significant difference in HPV vaccination acceptance between the two groups. The barriers on HPV vaccination were 'lack of information about HPV vaccine efficacy' and 'lack of information about HPV vaccination time and strategy', and there were significant differences in barriers on HPV vaccination between the two groups. Conclusion: The knowledge on HPV was low, and HPV vaccination was hindered due to lack of information about HPV vaccine despite their intention to obtain HPV vaccine. HPV education to promote HPV vaccination should be targeted among male students.

  • Purposes: This study was conducted in order to investigate the effects of passive music listening on psychological well-being and depression in 134 nursing students enrolled in two colleges of nursing in Kyeonggi-do, Korea. Methods: A prospective, pretest and posttest, controlled, quasi-experimental design was used. An intervention group (n= 74) participated in a 14-week passive music listening program before and after each lecture while those who were assigned as a control group (n=60) were given a series of traditional lectures. Analysis of data was performed using chi-square test, independent t-test, and Mann-Whitney U test, using SPSS 19.0. Results: Although no significant difference was observed in psychological well-being (t=0.34, p=.738), depression (z=-3.19, p=.001) showed a significant difference in the experimental group compared to the control group. Conclusions: This study provided evidence of the beneficial impact of passive music listening for nursing students with depression. Conduct of further studies will be needed in order to verify the effects on psychological well-being.

  • Introduction: Although continuing education is necessary for practicing nurses, it is very difficult to organize traditional classes because of large numbers of nurses and working shifts. Considering the increasing development of mobile electronic learning, we carried out a study to compare effects of the traditional face to face method with mobile learning delivered as text messages by cell phone. Materials and Methods: Sixty female nurses working in our hospital were randomly divided into class and short message service (SMS) groups. Lessons concerning breast cancer screening were prepared as 54 messages and sent in 17 days for the SMS group, while the class group participated in a class held by a university lecturer of breast and cancer surgery. Pre- and post-tests were undertaken for both groups at the same time; a retention test also was performed one month later. For statistical analysis, the paired T test and the independent sample T test were used with SPSS software version 16; p<0.05 was considered significant. Results: Mean age and mean work experience of participants in class and SMS groups was $35.8{\pm}7.2$, $9.8{\pm}6.7$, $35.4{\pm}7.3$, and $11.5{\pm}8.5$, respectively. There was a significant increase in mean score post-tests (compared with pretests) in both groups (p<0.05). Although a better improvement in scores of retention tests was demonstrated in the SMS group, the mean subtraction value of the post- and pretests as well as retention- and pretests showed no significant difference between the 2 groups (p=0.3 and p =0.2, respectively). Conclusions: Our study shows that teaching via SMS may probably replace traditional face to face teaching for continuing education in working nurses. Larger studies are suggested to confirm this.

  • The purpose of this study was to identify the significant predictors of drinking problem among college students attending health and welfare department. A total of 538 college students attending health and welfare department were selected through convenient sampling. Data were collected using self-reporting questionnaires, which were constructed to include depression, anxiety, abstinence self-efficacy, and drinking behavior. SPSS 18.0 was used for data analysis and descriptive statistics, t-test, ANOVA, Scheffe's test, Pearson Correlation coefficients, and multiple regression were done. Drinking problem was positively correlated to the depression and anger while negatively correlated to the abstinence self-efficacy. The significant predictors of drinking behavior were sex, grade, anxiety, and abstinence self-efficacy. The result of this study suggest that drinking problem prevention program should consider improving self management skills by effective management of negative emotions along with enhancing self-efficacy as a cognitive strategy.

  • In this study, the effect of the automotive haptic-seat technology which can transmit the driving information by the vibro-stimulus from the seat was investigated to overcome previous system's limitation relied on the visual and audial method and to help handicap driving. A prototype haptic seat cover with 30 coin-type motors and driver module were developed for this sake. In an experiment of seat vibration stimulation being performed under virtual driving situation by targeting the elderly aged over 65 years old, average score of test subjects for total vibration recognition was 3.5/4 points and recognition rate of 87.5% was represented. In addition, a result that all the test subjects totally recognized overspeed warning signal of 4 times was represented. As a result of statistical analysis for vibration recognition score by each group depending on TMT score, a significant difference was not found and a result that tactile function of which vibration is recognized even by the aged whose visual, perceptional function is declined showed an equal ability was obtained.. In this study it was shown that the seat vibration stimulus could be used to transfer the old drivers' information while driving.
