  • In this study, we analyze the antioxidant and anti-inflammatory activities of various extracts of Cryptoporus volvatus. Three extracts were prepared using hot-water, 70% ethanol, and 70% methanol. Compared to the hot-water and 70% methanol extracts, the 70% C. volvatus ethanol extracts showed significantly higher DPPH radical scavenging activities (76.1%), nitrite scavenging activities (29.5%), and total polyphenol content (9.17 mg GAE/g). The DPPH radical and nitrite scavenging activities of C. volvatus both correlated significantly with the total polyphenol content. The Pearson's correlation coefficient of DPPH radical and nitrite scavenging activities with total polyphenol content were r = 0.744 (p<0.05) and r = 0.921 (p<0.01), respectively. To test their anti-inflammatory effects, nitric oxide production and cell viability were measured by performing nitric oxide (NO) and MTT assays on lipopolysaccharide-treated RAW 264.7 cells. The NO production levels of the 70% ethanol extract-treated cells were slightly lower than those of the others. In our MTT assay, the hot-water extracts showed higher cell viabilities (81.4%) than those of 70% ethanol and 70% methanol extracts. The ${\beta}$-glucan content of C. volvatus was 37.8%. From the results of this study, it is suggested that C. volvatus, an easily accessible wild mushroom, has potential to be used in the development of medicines, cosmetics, and functional health foods.

  • Purpose: This study aimed to identify utilization of the work-family support policy (WFSP) and factors affecting retention intention among Korean female military officers. Methods: This cross-sectional survey recruited 103 married female officers from the Korean Army, Navy, and Air force with preschool-aged children through convenience and snowball sampling. Via online surveys from June to November, 2018, the participants self-reported retention intention, work-family conflict, job satisfaction, and utilization of the WFSP. The data were analyzed using descriptive statistics, independent t-tests, one-way analysis of variance, Pearson's correlation coefficient, and multiple linear regression. Results: Retention intention ($22.29{\pm}5.98$) was reported at the mid-level, lower than scores reported in the literature for female workers. Work-family conflict ($32.51{\pm}5.29$) and job satisfaction ($63.10{\pm}7.45$) were above the midpoint levels. Use of maternity leave (100.0%) and parental leave (92.2%) was high, especially compared to the rates of child-care day off (20.4%) and parenting time (20.4%). 'Noticeable increases in childcare services within the army' (22.8%) was reported as the supportive measure needed the most by female military officers. Job satisfaction (${\beta}=.43$, $p{\leq}.001$), the use of parenting time (${\beta}=-0.29$, p=.002), living type (${\beta}=-.18$, p=.043), and service type (${\beta}=-.16$, p=.035) significantly influenced retention intention. Conclusions: The findings highlight the priority areas of importance within the WFSP and suggest that a family-friendly culture can improve female officers' retention intention. Accordingly, policy changes at the Ministry of National Defense improving the system to enhance a family-friendly culture in the military is expected to strengthen the retention intention of female officers and contribute to excellence in the military workforce.

  • This study was aimed to reveal that the usual cold or heat state was associated with hypertension and could be a risk. We emailed educational personnel in D university to join this study and 182 subjects participated in from March to December in 2016. The usual cold or heat diagnosis was conducted by two experts who had over 10 years expertise. The blood pressure was measured from the subjected after 10 minute rest with Jawon medical device. The hypertension was diagnosed by the guide of the Seventh Report of the Joint National Committee on Prevention, Detection, Evaluation, and Treatment of High Blood Pressure. The frequency analysis was used in general characteristics, Pearson's Correlation Coefficient analysis was conducted in among continuous variables, and chi-square test was also used between hypertension and cold or heat group. Logistic regression was analyzed to generate the odds ratios (ORs) and 95% confidence interval (CI) for hypertension. The cold score was suggested to have negative association with Body mass Index (BMI, -.374, p<.001), systolic blood pressure (-.333, p<.001), and diastolic pressure (-.261, p<.001). The heat score was analyzed to have positive association with Body mass Index (.413, p<.001), systolic blood pressure (.249, p<.001), and diastolic pressure (.156, p<.001). The distribution of the cold group (35.1%) and non-cold group (64.9%) in hypertension was significantly different (p=0.18). The distribution of the heat group (62.2%) and non-heat group (37.8%) was significantly different (p=0.27). The usual cold was associated with decreased ORs (ORs 0.405, 95% CI=0.191-0.857), and usual heat was associated with increased ORs (ORs 2.327, 95% CI=1.108-4.888). However, after adjusting body mass index, sex, and smoking, the association was not significantly different. It is possible that usual cold or heat associate with hypertension. Further study is needed to show that usual heat may be a independent risk factor for hypertension through follow up design.
