A general screening test for the expression of antioxidative activity was performed on over 36 cultures belong to yeast isolated from soy sauce, Makkuli, and molasses. Antioxidative activities of yeasts were examined by measuring oxidation such as peroxide value and thiobarbituric acid value in fish oil. Of these cultures, Saccharomyces cerevisiae IFO 2114 were found to have strong antioxidative activity. Saccharomyces rouxii and Torulopsis etchellsii isolated from soy sauce showed the strongest antioxidative activity among yeasts. Pichia ohmerii isolated from Makkuli showed the strongest antioxidative activity and Candida versatilis isolated from molasses showed also relative strong antioxidative activity.

The purpose of this paper is to study the source term behavior after severe accidents by using a semi-kinetic model for simulation and calculation of in-containment activity. The reactor containment specification and the safety features of the containment under different accident conditions play a great role in evaluating the in-containment activity. Assuming in-vessel and instantaneous release of radioactivity into the containment, the behavior of in-containment isotopic activity is studied for noble gasses (Kr and Xe) and the more volatile elements of iodine, cesium, and aerosols such as Te, Rb and Sr as illustrative examples of source term release under LOCA conditions. The results of the activity removal mechanisms indicates that the impact of volumetric leakage rate for noble gasses is important during the accident, while the influence of deposition on the containment surfaces for cesium, mainly iodine isotopes and aerosol has the largest contribution in removal of activity during evolution of the accident.

In this study, mixed plant extracts including Phellodendro namurense and Eucommia ulmides Oliv were tested for antimicrobial activity and safety. Antimicrobial activity was measured by disc diffusion method using normal skin flora and opportunistic microbes such as Staphylococcus aureus, Pseudomonas aeruginosa, Escherichia coli and Candida albicans. As safety test, single dose oral toxicity test, single dose inhalation toxicity test and repeat dose inhalation toxicity test were done. From antimicrobial test, plant extracts showed significant antimicrobial activity Staphylococcus aureus, Pseudomonas aeruginosa, Candida albicans, however, did not indicate any antibacterial effect on Escherichia coli. From 3 kinds of safety tests, toxicity of mixed plant extracts was not observed. From experimental results, mixed plant extracts including Phellodendro namurense and Eucommia ulmides Oliv showed good potential for natural antimicrobial agent.

This study aimed to assess the in vitro safety of a probiotics mixture (Lactobacillus acidophilus PBS066, Lactiplantibacillus plantarum PBS067, and Limosilactobacillus reuteri PBS072), along with its inhibitory effect on carbohydrate digestion. All three strains met the antibiotic resistance profile of the European Food Safety Authority (EFSA) guidelines. None of the strains exhibited hemolytic activity or cytotoxicity against Caco-2 cells. Strains PBS067 and PBS072 inhibited α-amylase activity, whereas all three strains suppressed α-glucosidase activity, indicating that the mixture might limit carbohydrate digestion in the gastrointestinal tract. These findings support the safety of this probiotics mixture and its potential to modulate carbohydrate metabolism in the gut.

Objective: The purpose of this study was to analyze the Nuri-curriculum daycare programs for 3, 4, and 5-year-olds based on the Child Welfare Act. Methods: Data were analyzed according to the analysis criteria for 195 children's safety education programs in the Nuri-Program. The analyzed data used frequency and percentages. Results: First, life safety education was the most important element. And after looking at the contents category of the Child Welfare Act, the results in order are as follows: "raffic safety"; "Health and hygiene management, including the prevention of contagious diseases and drug abuse"; "Safety measures against disasters"; "Precaution and prevention of disappearance and abduction"; and "Prevention of sexual violence and child abuse." Second, there were many safety education activities in accordance to chronological age (3-to 5-years old). Health and safety by subject, season, and life tools were more frequent. By type of activity, conversation and language activity, fairy tales, and plays were the most common activities. Conclusion/Implications: This suggests the need to systematically plan safety education content through a program that links safety-related laws and elements related to the Nuri curriculum in child care centers.

An anti-fungal material produced by actinomycetes was isolated from domestic soil. This actinomycetes was identified as Streptomyces albogriseus by 16S rDNA sequence. YEME (yeast extract 4 g, malt extract 10 g, glucose 4 g, D.W 1l, pH 7.00.2) medium was used for production of anti-fungal materials. S. albogriseus was cultured in a shaking incubator for 2 weeks at 150 rpm and $25^{\circ}C$. An anti-fungal material produced by S. albogriseus was identified at 340 nm by uv/vis- spectrometer and it showed powerful anti-fungal activity. This is the first report that secondary metabolite produced by S. albogriseus showed an activity against phytopathogenic fungi such as Collectrichum coccodes, Botrytis cinerea, Cladosporium cucumerinum, Didymella bryoniae.

Background: Firefighting involves exposure of firefighters to risks related to this activity, serious injuries, and occupational diseases are recorded. There are other consequences such as thermal and emotional stress. This systematic review is proposed in order to analyze the risks and consequences faced by these workers and thus provide elements to improve safety management systems in institutions. Method: A descriptive observational study of systematic literature review on the risks and consequences of exposure to firefighters' activity was proposed, and the information was analyzed and described based on the available data and according to the variables determined. Results: The studies showed data on mechanical, physical, chemical, psychosocial risks, workers' perception and resilience, and epidemiological data. Information related to firefighters' activity on falls and slips, exposure to noise, and high concentrations of carbon monoxide is detailed. In addition, the relationship between burnout, cognitive, and physical fatigue as adverse effects on health and performance is mentioned. Conclusions: Among the preventive measures, the use of personal protective equipment is suggested, incorporation in prevention programs of information on exposure to risk factors, as well as the implementation of models that can predict the perception of workers, additionally, the generation of management systems with safety climate models for fire departments.

We evaluated the eating pattern, physical activity, and daytime sleepiness level in Chilean shift workers. Fifty, middle-aged adult health workers from a public hospital in Santiago, Chile, were included: a group undergoing shift work (shift workers, including at least one "night shift" and one "long day", n = 33), and day workers under traditional schedule (from 8:00 to 17:00h, n = 17). Body composition, physical activity, and daytime sleepiness levels, and diet characteristics (diet composition, meals' timing, and diet quality) were assessed. Despite similar total energy intake, shift worker showed lower carbohydrate (% of energy) and higher protein intake (both P < 0.01), decreased diet quality, an irregular eating pattern, and delayed meal timing (all P < 0.05). Physical activity and daytime sleepiness levels did not differ between groups. Findings from this first Chilean study in healthcare shift workers support the fact that meal timing and diet quality appear as critical factors for upcoming intervention studies in this group.

Purpose: This study was conducted to determine the neighborhood environmental factors associated with physical activity among adults living in rural communities. Methods: A cross-sectional descriptive survey was conducted with a convenience sample of 201 adults living in three Ri in Y-city, Gyeonggi-do. Data were collected from face-to-face interview by trained interviewers and were analyzed using a zero-inflated negative binominal regression model. Results: Participants reported engaged in moderate or vigorous physical activity was 76.1%; 10.5% of participants reported that they met moderate physical activity recommendations and 14.5% of participants reported that they met vigorous physical activity recommendations. Zero-inflated negative binominal regression analysis showed association of increasing days of physical activity with social cohesion (${\beta}=.130$, p=.005), social network (${\beta}=-.096$, p=.003), and safety for crime (${\beta}=-.151$, p=.036), and no days of physical activity was associated with no attainment of education and marginally associated with increasing BMI. Conclusion: Neighborhood environmental factors including social cohesion, social network, and crime for safety were significantly associated with physical activity of rural adults. Community health nurses should expand an approach for individual behavior change to incorporate rural adults' specific neighborhood environmental factors into physical activity interventions.
