The present study was conducted to investigate the effects of flowers ethanol extract of Elsholtzia splendens (ESE) on the antioxidant defence system in mice with 7,12-dimethylbenz(a)anthracene (DMBA)-induced oxidative stress. The ESE was pre-administered orally to 2 groups of mice at 10 and 50mg/kg body weight (BW) for 5 weeks. Subsequently, mice with pretreatment of ESE received DMBA intragastrically at a dose of 34 mg/kg BW twice a week for 2 weeks. In DMBA alone group, biomarkers of oxidative stress (TBARS value, carbonyl content, and serum 8-OH-dG) were significantly increased. Also, the antioxidant enzymes were down-regulated. ESE significantly restored the TBARS value and carbonyl content at both doses, while a decrease in the elevated serum 8-OH-dG content was observed only at the higher dose. The DMBA-induced decreases in catalase and superoxide dismutase (SOD) activities were restored to nearly control levels by ESE. Glutathione peroxidase (GSH-px) and glutathione reductase (GR) activities, as well as the reduced glutathione (GSH)/oxidized GSH (GSSG) ratio, were significantly affected by ESE at the higher dose. These results suggest that ESE possesses antioxidant activity, which plays a protective role against DMBA-induced oxidative stress.

Purpose: The purpose of this study was to explore preserved belief system supporting Korean immigrant women's Taekyo practices and influencing factors while they observe the tradition within US sociocultural context. Methods: Leininger's exploratory focused ethnographic approach was used. Semi-structured in-depth interviews were conducted with purposive sample of sixteen Korean immigrant women who gave birth in the US within last 6 months. Researcher's observation and reflective field notes were also integrated into the interview data. Leininger and McFarland's four phases of ethnographic analysis guided data analysis process. Results: The perceived belief system supporting Taekyo practices included Taekyo as an enculturated Korean tradition, connecting parents with fetus, and positive impacts on fetal development. And Korean immigrant women's Taekyo practices were influenced by resources of information, woman's orientation toward Taekyo, pressure from local Korean community, and child order. Conclusion: The findings from this research would serve as an important knowledge base to expand US health care providers' understanding of Korean traditional Taekyo practices observed by Korean immigrant women's as important prenatal self-care practices. The findings could also aid in providing more patient-centered and culturally-tailored prenatal care plan to Korean immigrant by including Korean traditional belief system supporting Taekyo practices.

This study examined the relationship between NaCl sensitivity and stress response of Listeria monocytogenes. Nine strains of L. monocytogenes (NCCP10805, NCCP10806, NCCP10807, NCCP10808, NCCP10809, NCCP10810, NCCP10811, NCCP10920 and NCCP 10943) were exposed to 0%, 1%, 2% and 4% NaCl, and then incubated at 60℃ for 60 min to select strains that were heat-sensitized (HS) and non-sensitized (NS) by NaCl exposure. After heat challenge, L. monocytogenes strains were categorized as HS (NCCP 10805, NCCP10806, NCCP10807, NCCP10810, NCCP10811 and NCCP10920) or NS (NCCP10808, NCCP10809 and NCCP10943). Total mRNA was extracted from a HS strain (NCCP10811) and two NS strains (NCCP10808 and NCCP10809), and then cDNA was prepared to analyze the expression of genes (inlA, inlB, opuC, betL, gbuB, osmC and ctc) that may be altered in response to NaCl stress, by qRT-PCR. The expression levels of two invasion-related genes (inlA and inlB) and two stress response genes (opuC and ctc) were increased (p<0.05) in NS strains after NaCl exposure in an NaCl concentration-dependent manner. However, only betL expression was increased (p<0.05) in the HS strains. These results indicate that the effect of NaCl on heat sensitization of L. monocytogenes is strain dependent and that opuC and ctc may prevent NS L. monocytogenes strains from being heat sensitized by NaCl. Moreover, NaCl also increases the expression of invasion-related genes (inlA and inlB).

The objective of this study was to evaluate the risk of illness from Campylobacter spp. on ham. To identify the hazards of Campylobacter spp. on ham, the general characteristics and microbial criteria for Campylobacter spp., and campylobacteriosis outbreaks were investigated. In the exposure assessment, the prevalence of Campylobacter spp. on ham was evaluated, and the probabilistic distributions for the temperature of ham surfaces in retail markets and home refrigerators were prepared. In addition, the raw data from the Korea National Health and Nutrition Examination Survey (KNHNES) 2012 were used to estimate the consumption amount and frequency of ham. In the hazard characterization, the Beta-Poisson model for Campylobacter spp. infection was used. For risk characterization, a simulation model was developed using the collected data, and the risk of Campylobacter spp. on ham was estimated with @RISK. The Campylobacter spp. cell counts on ham samples were below the detection limit (<0.70 Log CFU/g). The daily consumption of ham was 23.93 g per person, and the consumption frequency was 11.57%. The simulated mean value of the initial contamination level of Campylobacter spp. on ham was −3.95 Log CFU/g, and the mean value of ham for probable risk per person per day was 2.20×10⁻¹². It is considered that the risk of foodborne illness for Campylobacter spp. was low. Furthermore, these results indicate that the microbial risk assessment of Campylobacter spp. in this study should be useful in providing scientific evidence to set up the criteria of Campylobacter spp..

Purpose - While sustainability is based on the argument that the world's resources are finite and their demand will ultimately surpass supply, entrepreneurship on the other hand argues that there are inherent opportunities to address this through conserving, recycling, switching to more renewable resources and making effective use of available finite resources. Research design, data, and methodology - In response to the lack of scientific information on the outcomes of entrepreneurship in rural Nigeria, this paper surveys the benefits (social, economic and environmental) of women engagement in waste plastic bags recycling in Adamawa State of Nigeria. A descriptive research design was adopted and data was collected from 26 respondents with the use of a semi-structured questionnaire, which was analyzed using descriptive statistics and presented in frequency tables. Results - Results indicated that 21 women have gained employment, who would have remained unemployed; 80.8% of who make profits below 10000 Naira per month and collectively, they recycle 179.3kg of waste polythene bag per month. Conclusions - It was recommended that the women should be further their education; adequate records of costs and sales should be kept; and savings should be encouraged among them.

The objective of this study was to evaluate novel usability as natural anti-obesity supplement of Selaginella tamariscina extract. The total phenol contents and total flavonoid contents were $60.29{\pm}3.11GAE\;mg/g$ and $14.90{\pm}0.34QE\;mg/g$, respectively. To evaluate anti-obesity activity of Selaginella tamariscina extract, pancreatic lipase inhibition activity as well as its inhibition effect of lipid accumulation in adipocytes were conducted by Oil Red O staining and lipolysis assay. The result of pancreatic lipase inhibition activity of S. tamariscina extract showed a wide range between 40 and 73% dose dependently. While the incubation of 3T3-L1 cells with S. tamariscina extract inhibited differentiation of preadipocytes and reduced lipid accumulation, the level of released free glycerol into culturing medium was increased in multiple concentrations. These results showed that S. tamariscina extract inhibit adipogenesis and pancreatic lipase activity. Thus, S. tamariscina extract can be a candidate for regulating lipid accumulation in obesity.

Objectives: The primary objective of this study was to examine the effect of women's empowerment on the immunization of Indonesian children. The secondary objective was to examine the effect of wealth as a factor modifying this association. Methods: We utilized data from the 2017 Indonesian Demographic and Health Survey (IDHS). The subjects were married women with children aged 12-23 months (n=3532). Complete immunization was defined using the 2017 IDHS definition. Multiple components of women's empowerment were measured: enabling resources, decision-making involvement, and attitude toward intimate partner violence. The primary analysis was conducted using binomial logistic regression. Model 1 represented only the indicators of women's empowerment and model 2 controlled for socio-demographic variables. Subgroup analyses were conducted for each wealth group. Results: The primary analysis using model 1 identified several empowerment indicators that facilitated complete immunization. The analysis using model 2 found that maternal education and involvement in decision-making processes facilitated complete immunization in children. Subgroup analyses identified that wealth had a modifying effect. The indicators of women's empowerment were strong determinants of complete immunization in lower wealth quintiles but insignificant in middle-income and higher-income quintiles. Conclusions: To our knowledge, this study is the first to explore women's empowerment as a determinant of child immunization in Indonesia. The results indicate that women's empowerment must be considered in Indonesia's child immunization program. Women's empowerment was not found to be a determinant in higher wealth quintiles, which led us to rethink the conceptual framework of the effect of women's empowerment on health outcomes.

The purpose of this study is to propose measures for social work practice to enhance the happiness of middle-aged married men and women by identifying the effects of family stress and social support resources (formal and informal support resources) on marital satisfaction among mid-life married couples. Subjects were selected through purposive sampling among married men and women aged between 40 and 59 and living in Seoul City and Gyeonggi province. The study results are follows. First, the average score of family stress was 3.06 points (SD=.56), slightly higher than the median value of 3 points. Of all subscales of family stress, the subjects experienced the most stress from family relationships, followed by financial problems, health and loss of families, and work-family compatibility. In regard to social support resources, the mean value of all social support resources categories was greater than the median. Among the subscales, informal support (family support and support from other people) was found to be higher than formal support. The level of marital satisfaction was higher than the median, and the score was 3.21 points (SD=.78). Second, in order to explore differences in marital satisfaction according to family stress and social support, differences in marital satisfaction were analyzed by grouping subjects who scored high, middle, and low levels of marital satisfaction. According to the results, marital satisfaction was statistically significantly higher in the group that experienced less family stress (F=6.25, p<.01). With respect to social support, marital satisfaction was statistically significantly higher in the group that received high social support (F=29.68, p<.001). Third, according to the analysis of factors affecting marital satisfaction in middle-aged married men and women, subjective economic status, family relationship stress, economic stress, and family support showed statistical significance. The higher the subjective economic status and the lower the family relationship stress and economic stress levels, the higher the marital satisfaction among middle-aged married men and women. In addition, the greater the family support, the higher the marital satisfaction. The results of this study underscore the need to improve family relationships in middle-aged married couples and to distribute family life education programs that can strengthen family support resources. For example, family relationship enhancement programs are currently performed, including "Family School for Middle-Aged Baby Boomers" and others as part of the Healthy Family Support Work regarding the promotion of marital satisfaction of middle-aged couples. In addition, continuing effort is warranted to include content on strengthening family support resources, maximizing the effectiveness of programs, and promoting service accessibility.
