Urinary tract infection (UTI) is one of the most common bacterial infections and is predominantly caused by uropathogenic Escherichia coli (UPEC). UPEC strains generally possess several genes encoding virulent factors, which are mostly adhesins, toxins, bacteriocin and siderophores. E. coli is composed of four main phylogenetic group (A, B1, B2, D) and virulent extra-intestinal strains mainly belong to groups B2 and D. Prescription of ciprofloxacin, a kind of fluoroquinolone group antibiotics, is increasing now a days, but resistance to this drug is also increasing. A total of 188 strains of E. coli were collected. Thirteen strains were collected from healthy students in 2011 and 175 strains from patients with urinary tract infection in 2010. Virulence factor genes (papC, fimG/H, sfaD/E, hlyA, cnf1, and usp) were amplified by polymerase chain reaction (PCR) methods for phylogenetic group (A, B1, B2, D) detection. Ciprofloxacin susceptibility test was performed by disk diffusion method. The identified virulence factors (VFs), phylogenetic groups and ciprofloxacin resistance in 13 E. coli strains isolated from healthy students were papC (15.4%), fimG/H (76.9%), sfaD/E (30.8%), hlyA (23.1%), cnf1 (23.1%), usp (7.7%), phylogenetic group A (23%), B1 (8%), B2 (46%), D (23%) and ciprofloxacin resistance (7.7%), while those of in 175 E. coli strains isolated from patients with UTI were papC (41.1%), fimG/H (92.5%), sfaD/E (30.3%), hlyA (10.3%), cnf1 (30.3%), usp (27.4%), phylogenetic group A (9.1%), B1 (5.1%), B2 (60.6%), D (25.1%) and ciprofloxacin resistance (29.7%). In this study, 10 out of 13 E. coli strains (76.9%) from healthy students were found to possess more than one virulence factor associated with adhesion. In addition, one E. coli strain isolated from healthy students who had never been infected with UPEC showed ciprofloxacin resistance. According to these results between the virulence factors and phylogenetic groups it was closely associated, and UPEC strains isolated from patients showed high level of ciprofloxacin resistance.

Purpose: This study compared the effects of two six-week school-based intervention programs - a health promotion program using a school forest and a traditional school health promotion program (TSHPP) - on physical and mental health among elementary school students. Methods: A total of 73 students participated in the study: 21 students in the 6-week school forest program conducted in a rural area and 52 students in the 6-week TSHPP conducted in an urban area. Children's health promotion behavior, depression and hyperactivity were measured using a self-report questionnaire. To assess children's physical health, body mass index (BMI), body fat percentage, and heart rate variability (HRV) were used. Results: Overall, both intervention programs improved participants' physical and mental health. Both programs significantly decreased the body fat percentage; this effect was more prominent in the TSHPP group. Only the TSHPP significantly decreased the participants' BMI after the intervention. The school forest group showed significantly improved relaxation and diminished hyperactivity; the TSHPP group showed significantly improved health promoting behavior and social relationship after the intervention. Comparing the two groups'post-pre difference scores, the two groups significantly differed only in social relationship. Both group showed significantly improved depression after the intervention. Conclusion: These findings support the effectiveness of these 6-week school-based health promotion programs in improving physical and mental health among school-aged children.

Purpose: The purpose of this study was to investigate influencing factors in self-efficacy among college students. Methods: The sample consisted of 553 college students in C & K cities. Self-report questionnaires were used to measure the variables. In data analysis, SPSS WIN 20.0 program was utilized for descriptive statistics, Pearson's correlation coefficients, and regression analysis. Results: The mean score for Self-Efficacy was 66.62. Self-Efficacy was significantly different according to gender(t=2.076, p=.038), grade(F=11.077, p<.001), religion(F=4.666, p=.003), major(F=19.598, p<.001), economic status(F=6.570, p<.001), perceived health status(F=6.168, p<.001), and self-rated knowledge about health(F=12.936, p<.001). Multivariate analysis showed that major, self-rated knowledge about health, economic status, and perceived health status were significant predictors of self-efficacy and could explain 15.9% of total variability in this model. Conclusion: This study suggests that perceived health status and self-rated knowledge about health are significant factors in self-efficacy among college students. Therefore, the strategies of nursing intervention which improve these variables must be developed for college students.

The use of earphones has recently been widely used around the world. In currently, students wear earphones a lot in a daily life. The types of earphones are open-earphones, Canalphones, and headphones. Many students don't periodically to sterilization their earphones. Therefore, it can be an incubator that can induced ear infections. The objective of this study was to detect the pathogenic bacteria from the earphones used by the students. A total of 3 type earphones swabs were collected by sterile cotton swabs. The swabs were inoculated onto BHI agar and incubated aerobically 48 hour at 37℃. 16s rRNA PCR, electrophoresis and sequencing were performed to confirm the identification of all the bacterial isolates. As a result, 24 pathogens were identified in sequencing. Three types of earphones were sterilized in three ways: ultraviolet (UV), 70% ethyl alcohol, and antibacterial wet tissue. If you use earphones for a long time without disinfecting them for a long time, it causes various diseases such as external ear infections. The findings of this study the users periodically to sterilization their respective earphones.

Since students of the College of Maritime Sciences will become professionals contributing to the development of the Korean shipping industry after graduation, they are required to successfully complete school life including theoretical and practical curriculum with health promotion behavior. The purpose of this study was to investigate the factors influencing health promotion behavior by students of the College of Maritime Science in order to collect basic data through a survey for the development of health promotion programs. Health promotion behavior by students of the College of Maritime Sciences was less frequent than by other college students, and the levels of health promotion behavior sub-domains were lower in order of interpersonal relations, spiritual growth, stress management, nutrition, physical activity, and health responsibility. The most influential factors for health promotion behavior were learner participation, health promotion self-efficacy, self-esteem, and social support. It is necessary to develop a differentiated health promotion program considering the characteristics of students and to apply it systematically from the time of admission to improve health promotion behavior by students of the College of Maritime Sciences.
