This study examined the factors associated with recurrent falls among the community-dwelling elderly. The participants were 329 community-dwelling elderly. The data was collected from February 5, 2010 to February 14, 2010. Over the past 1 year, 14.3% of the 329 participants fall once, and 4.0% experienced recurrent falls. There was a significant difference among the non fallers, single faller and recurrent fallers with regard to the static balance(F=5.86, p=.003), dynamic balance(F=24.32, p<.001), risk of fall(F=9.94, p<.001) and compliance of prevention behavior related to falls(F=3.09, p=.047). The analysis results for the correlation between variables showed that the number of falls had a negative effect on the knee flexors muscular strength(r=-.15, p=.008), static balance(r=-.16, p=.004) and compliance of prevention behavior related to falls(r=-.12, p=.030) and a positive affect for the dynamic balance(r=.26, p<.001), depression(r=.13, p=.019) and risk of falls(r=.30, p<.001). The variables explained 36.0% of the variants in the occurrence of recurrent falls. Therefore, an effective recurrent fall prevention program should focus on multiple risk factor intervention.

Purpose: This study aimed to determine how undergraduate nursing students' knowledge and health beliefs affected their COVID-19-related infection-prevention behaviors. Methods: This study used a descriptive survey. A total of 188 undergraduate nursing students from two universities in South Korea participated in this study. The data were collected from June 2020 to August 2020. Factors influencing infection-prevention behaviors were identified using multiple regression analysis. Results: The participants' mean knowledge level regarding COVID-19 was 84.05 ± 11.78 out of 100. The average health belief score was 2.80 ± 0.32 points out of 5. COVID-19-related preventive health behaviors were correlated with experiences of searching for COVID-19 information (r = .22, p < .01), perceived severity (r = .24, p < .01), perceived benefits (r = .29, p < .01), cues to action (r = .30, p < .01), knowledge (r = .27, p < .01), and perceived barriers (r = - .19, p < .05). Factors that significantly affected COVID-19-related preventive health behaviors were the participants' years of study, experiences regarding COVID-19 prevention education, perceived severity, perceived barriers, and cues to action. Conclusion: COVID-19-related preventive health behaviors are promoted by increasing awareness about the disease and promoting COVID-19 education in nursing curriculums.

This study was conducted to evaluate the spirituality, perceived meaning in life, hospice perception, and attitudes towards terminal care among nursing students, as well as to identify the relationships between variables and examine factors influencing their attitudes towards terminal care. Data were collected using a self-reported questionnaire completed by 308 nursing students at two universities from April 11, 2017 to April 17, 2017. Data were analyzed using descriptive analysis, a t-test, Pearson's correlation coefficients and stepwise multiple regression with the SPSS/Win 14.0 program. Attitudes toward terminal care among nursing students were significantly correlated with hospice perception(r=0.30, p<0.001) and meaning in life(r=0.30, p<0.001). Meaning in life among nursing students was significantly correlated with hospice perception(r=0.25, p<0.01) and spirituality(r=0.53, p<0.01). The significant predictors of the attitudes towards terminal care in nursing students were hospice perception(${\beta}=0.40$, p<0.001) and meaning in life(${\beta}=0.27$, p<0.001). Hospice perception explained 22.7% and meaning in life explained 5.0% of the variance. These variables explained 27.7% of the variance in attitudes toward terminal care. Overall, these findings suggest that the terminal care education program, including hospice perception and meaning in life, is necessary to enhance the positive attitude toward terminal care among nursing students.

In this paper we examine a total of 16 dipolarization events that were observed by THEMIS spacecraft in space close to geosynchronous orbit, r < ${\sim}7\;R_E$. For the identified events, we examine the characteristics of the plasma flows and associated bubbles as defined based on $pV^{5/3}$, where p is the plasma pressure and V the volume of unit magnetic flux. First, we find that the flow speed in the near-geosynchronous region is very low, mostly within a few tens of km/s, except for a very few events for which the flow can rise up to ~200 km/s but only very near the dipolarization onset time. Second, the bubble parameter, $pV^{5/3}$, decreases by a much smaller factor after the dipolarization onset than for the events in the farther out tail region. We suggest that the magnetic dipolarization in the near-geosynchronous region generates or is associated with only very weak plasma bubbles. Such bubbles in the near-geosynchronous region would penetrate earthward only by a small distance before they stop at an equilibrium position or drift around the Earth.

This study was performed to select protease-producing Bacillus sp. as a potential probiotic starter for fermented meat products. In order to isolate protease-producing bacterium from meju, measured the diameter of the clear zone on agar plate (TSA, 1% (w/v) skim milk) and analyzed for intracellular protease activity, then 10 Bacillus-like strains were isolated. Three Bacillus-like strains (P19, P27, and P33) among 10 strains were able to tolerate in acidic condition (TSB, pH 2.5, 2 h incubation). These 3 strains were showed antimicrobial activity against food-borne pathogenic bacteria. These vegetative cells of 3 strains were showed a survival rate of 0.04% to 0.08% under the artificial gastric acidic condition (TSB, pH 2.5 with 1% (w/v) pepsin), but spore-forming cells were 56.29% to 84.77%. Vegetative cells of 3 strains were the least bile-resistant, while spore-forming cells of 3 strains showed higher survival rate more than 76% under artificial bile condition (TSB, 0.1% (w/v) oxgall bile). In these strains, P27 strain was finally selected as a good probiotic strain. P27 strain was tentatively identified as Bacillus amyloliquefaciens by API CHB kit and 16S rDNA sequence analysis. The results of this study suggest that B. amyloliquefaciens P27 can be used as a potential probiotic starter for fermented meat product.

Four kinds of makgeolli brewed with different proportions of rice and wheat flour were prepared to investigate the effects of the carbohydrates source on the storage properties, and to examine the chemical characteristics and BA (biogenic amine) contents in makgeolli stored over 30 days at 4, 10 and $20^{\circ}C$, respectively. The chemical properties and BA contents were sustained at a consistent level for those makgeolli stored at $4^{\circ}C$ over 30 days. The alcohol content was significantly higher for makgeolli brewed with higher proportions of rice (R) over wheat flour (WF) (R 100: WF 0, R 70: WF 30) when compared with those brewed with a high proportion of wheat flour (R 30: WF 70, R 0: WF 100), and increased with increasing storage temperature and duration. The free amino acid contents of makgeolli brewed with high proportion of rice were significantly lower under the same conditions. Among the 8 BAs examined, tyramine, putrescine, cadaverine and phenylethylamine were detected, while tyramine and putrescine were mainly detected. Histamine was not detected throughout storage. Makgeolli brewed with rice as the only carbohydrate source exhibited very low levels of total BA during 30 days of storing at $20^{\circ}C$. Total BA contents of R100, R70, R30, R0 were 178.6, 682.9, 1186.7 and 1150.4 mg/L, respectively. These results suggest that makgeolli brewed with relatively higher proportions of rice have better storage properties and are safer for consumption.
