The purpose of this study is to identify nursing college students' knowledge, awareness and adherence to preventive behavior of blood-borne infection, and the factors affecting the adherence to preventive behavior of blood-borne infection. This study was carried out for 475 juniors in university who have completed clinical practice at the nursing college located in G city from December 1 to 15, 2017. The study findings showed that knowledge score, awareness and adherence to preventive behavior of blood-borne infection were 13.13 points(0-18 points), 4.18 points and 4.34 points, respectively. Nursing college students' adherence to preventive behavior of blood-borne infection showed a positive correlation between knowledge of blood-borne infection and awareness of blood-borne infection, The factors affecting the adherence to preventive behavior of blood-borne infection were found to be age, education experience, exposure, knowledge of blood infection, and the explanatory power of these variables was 16.3%. Therefore, it was found to be necessary to develop and apply a standardized education protocol in ward units for nursing college students to reduce the incidence of exposure to blood-borne infection sources in nursing college students.

As the viscosity of the blood increases, the blood becomes more sticky and difficult to flow, so the possibility of thrombosis increases and the probability of ischemic cerebral infarction increases. The importance of measuring blood viscosity has recently been emphasized for the prevention of circulatory system diseases, and the need for a viscometer capable of easily and accurately measuring blood viscosity has emerged. In this study, the measured values of a viscosity standard solution and an artificial blood by a parallel-plate viscometer ARS-Medi were compared with the those by Ares-G2 of TA instrument, which is internationally recognized for its accuracy and reliability. The viscosity of N44 standard solution, which is a Newtonian solution, was almost perfectly matched between the two instruments at all shear rates. In the case of an artificial blood, which is a non-Newtonian solution, the measured values between the two instruments showed a difference of about 10% at the lowest shear rate 1 rad/s; however, at a clinically significant shear rate of 10 rad/s or higher, the measured values between them were consistent within the error range. We expect that ARS-Medi, a newly developed parallel-plate viscometer for blood, using disposable plates, will be very useful in clinical practice as it improves the convenience and hygiene of blood viscosity measurement.

The demands for specially trained hemodialysis nurses are increasing as the population requiring maintenance hemodialysis expands. However, there has been no standardized training program for hemodialysis nurses in South Korea. The study was conducted to develop and evaluate a hemodialysis nurse educational program (HNEP). The effects of education using the HNEP were assessed by levels of hemodialysis-specific knowledge, self-efficacy and satisfaction. A total of 25 registered nurses participated in the HNEP which consists of 20 week education (classroom theory for 10 weeks and clinical practice for 10 weeks) between April and September, 2011. Knowledge levels were compared before and after the HNEP using paired t-test. Self-efficacy and satisfaction levels were also evaluated after the program using a scale of 1-5, 5 being the highest and 1 being the lowest. Knowledge levels were significantly increased after the HNEP (Mean=13.96 vs. 17.80, t=-7.748, p=<.001). Self-efficacy and satisfaction levels with the program were high, $3.90{\pm}0.42$ and $4.02{\pm}0.77$, respectively. These findings suggest that the HNEP improved hemodialysis-specific knowledge, and levels of self-efficacy and satisfaction with the HNEP were reasonably, among the participants.

The purpose of this study was to investigate the effects of maximum and endurance resistance exercises on total work, blood viscosity, and erythrocyte volume ratio. The study subjects were selected as 15 men in their twenties with 12 months or more of resistance exercise experience, and the bench press 1RM was measured before the experiment, and the experiment for each condition was cross-allocated at intervals of one week, and the maximum repetition was performed in 6 sets. As a result, the total amount of exercise showed that the muscular endurance strength was higher than that of the maximum muscular strength (p<.001), and the blood viscosity and erythrocyte volume ratio were higher after exercise than before (p<.01) regardless of the total exercise amount. In summary, it was found that blood viscosity was not affected by exercise intensity and amount of exercise, and increased with one-time resistance exercise. This is clinically significant in constructing a resistance exercise program, and it is considered to be a reference material in creating an exercise program for clinical patients related to vascular disease.

The purpose of this study was not only to identify the level of health literacy, self-management knowledge and self-care behavior, but also to identify the relations those variables in elders with hemodialysis. The subjects of this study are 193 patients from dialysis clinics of nine hospitals in Incheon who aging over 60 years old. Data collection was conducted by using Health Literacy Scale, Self-Management Knowledge Scale, and Self-Care Behavior Scale. The data were analysed by descriptive analysis, t-test, ANOVA, and Pearson correlation coefficient using SPSS statistics 23.0 program. In the results, average score of subjects' health literacy, self-management knowledge and self-care behavior were 13.66(±2.09), 13.33(±1.85) and 63.95(±10.32), respectively. There were significant positive correlation between self-management knowledge and health literacy (r=0.37, p<.001) and reading comprehension part which is subscale in health literacy (r=.25, p=.001). Also, there was significant positive correlation between self-management knowledge and self-care behavior (r=0.15, p<.05). According to the above results, for improving the self-care behaviors in elders with hemodialysis, it is necessary to provide tailored education based on his/her level of health literacy.

This study aimed to verify the hypothesis that urea denatures hemoglobin in the blood, thereby exposing active sites of enzymes and enhancing the chemiluminescence of the blood-luminol reaction. When blood was pretreated with urea, higher concentrations of pretreatment urea or longer pretreatment times resulted in enhanced chemiluminescence in the blood-luminol reaction, supporting the above hypothesis. However, the chemiluminescence was enhanced when blood was treated with luminol mixed with an 8 M urea solution, although the fact that the time for urea to denature hemoglobin was shorter compared to when blood was pretreated with urea and followed by luminol. In addition, the chemiluminescence was enhanced when a transition metal without hemoglobin was reacted with urea-containing luminol. Based on these results, it is anticipated that urea not only denatures hemoglobin but also plays a role in the luminol-hydrogen peroxide reaction.
