Antioxidant activity and antimutagenic activities with and without simulated gastric digestion of hot water extracts from white and yellow onions were investigated as compared to BHT and ascorbic acid as control Contents of total phenol and flavonoid in hot water extract of yellow onion were higher than those of white one. The scavenging activity of hydrogen peroxide of both extracts were increased in direct proportion to added their concentration. Antioxidant activity and reducing power of the hot water extract were elevated through analysis of $\beta-carotene-linoleate$ system and were lower than those of BHT and ascorbic acid. Antimutagenic activity after simulated gastric digestion of hot water extract of white and yellow onions was observed against mutagen IG and MNNG on Salmonella typhimurium TA80 and TA100. Extract of yellow onion was higher in antimutagenic activity than that of white one. In conclusion, these results suggested that phenol and flavonoid in hot water extract from yellow and white onions may play an important role in the antioxidant and antimutagenic activities. 양파 열수 추출물의 항산화능 및 인공소화 전과후의 항돌연변이 효과를 BHT와 ascorbic acid와 비교하여 조사하였다. 총 페놀 및 플라보노이드의 함량은 노란색 양파 추출물이 횐색 양파 추출물보다 많았으며, 양파 추출물의 과산화수소 소거능은 농도가 증가함에 따라 비례적으로 증가하였다. $\beta-carotene-linoleate\;system$에서 항산화능과 reducing power는 증가되었으나, BHT와 ascorbic acid보다는 낮았다. 양파열수 추출물의 인공소화 후에 IQ와 MNNG로 처리된 Salmonella typhimurium TA80과 TA100에 대하여 항돌연변이 효과가 나타났으며, 노란색 양파가 횐색 양파보다 높게 나타났다. 결론적으로 양파 추출물을 소화시키면 항산화 및 항돌연변이의 효과는 양파의 페놀과 플라보노이드의 성분 변화에 의한 것으로 판단된다.

김연희,주현실,이정언,이미선,Kim, Yeon Hee,Joo, Hyun Sil,Lee, Jeong Eon,Lee, Mi Sun 한국직업건강간호학회 2022 한국직업건강간호학회지 Vol.31 No.4

Purpose: This study aimed to compare and analyze the job stress of nurses with and without in COVID-19-related work. Methods: A structured self-reported questionnaire survey was conducted to assess job stress. The extent of job stress was compared between nurses with COVID-19 (COVID-19 group) and those without such experience (non-COVID-19 group). Multiple regression analysis was performed to identify the factors influencing job stress. Results: Job stress was higher in the COVID-19 group compared to the non-COVID-19 group (t=2.54, p=.12). In sub-categorical comparison, stress driven by a taxing work environment, relationship conflict, and work schedule was higher in the COVID-19 group than the non-COVID-19 group. Multiple regression analysis revealed the job stress was higher among nurses with COVID-19-related work experience than that of non-experienced nurses. The factors affecting job stress of nurses with COVID-19-related work experience included emergency room work, providing nursing assistant for COVID-patients, and caring for these patients. Conclusion: Since COVID-19-related work experience is a major factor that affects nurses' job stress, it is imperative to provide various support measures for nursing assistants such as providing a break from working in an environment with high risk of infection, adjusting work schedules, resolving conflicts between personnel, and securing support.

Purpose: The purpose of the study was to identify the relationship between low back pain and job stress in hospital nurses. Method: A descriptive correlation research design was employed. The participants were 355 nurses who worked in a general hospital in W city Kangwon-do and consented to participate in this study. The Visual Analog Scale and job stress scale were used in this study. Analysis included descriptive statistics, t-test, ANOVA, and partial correlation coefficients. Results: Experience of low back pain for nurse in the past was 86.5% and in the present was 67.5% for low back pain which measured an average of 4.4 points for the level of low back pain. The mean score for job stress was relatively low(M=47.2). Job demand, organization system, job instability and conflict in relationships contributed to high stress scores, instead inappropriate compensation, job culture, and job autonomy contributed to low stress. There was a significant relationship between low back pain and job stress. Conclusion: These results suggest that further research is needed to develop programs to prevention and management of low back pain for nurses.

What is the most important in articles of food is hygienic safety. Because food Is the most common thing in our everyday life, however, the importance of its hygienic safety and other many problems caused by food may be easily neglected. What is more, food is can be dangerous as much as it is directly related to human life and accidents from the same cause may have different effects on the victims according to physical and environmental differences of individuals. Thus PL action for food requires more thorough prevention and measure. Korea has been enforcing 'the Product Liability Act' since the 1/sup 1st/ of July 2002. Product Liability (PL) is liability of the manufacturer or the seller of a product to compensate for the death or injury of consumers or the loss of properties caused by the defect of the product. This study surveyed consumers' response to and the effects of the enforcement of the Product Liability Act, investigated how consumers perceived the importance of food safety and the risk of defective food based on PL standards and their experience in damage by food through a questionnaire survey, and analyzed collected data through empirical analyses (reliability analysis, factorial analysis, regression analysis and ANOVA t-test) using SPSS 10.0. Based on the results of analysis, the researcher proposed strategies for coping with the Product Liability Act in the food industry.

Objective: The purpose of this study was to evaluate the effect of polycystic ovarian follicular fluid on sperm motility in human in vitro fertilization (IVF). Methods: From May, 1998 to July, 1999, 55 patients who complained of infertility were involved in this study. We obtained ovarian follicular fluids from the patients by ultrasono-guided aspiration. Subjects were divided into two groups. 20 patients who had polycystic ovarian disease were belong to study group, and 25 patients who had normal ovarian follicular fluid were belong to control group. The follicular fluid dilution was done with Ham's fluid as 10%, 20%, 50%, 100%. The sperm motility was analyzed by CASA at 6hr and 12hr after incubation in follicular fluids. Results: The levels of average path velocity (VAP) in all concentration fluid didn't show significant difference between study and control group. The other parameters including curvilinear velocity (VCL), amplitude of lateral head displacement (ALH), and linerity (LIN) were didn't show any significant difference between both groups. Conclusion: PCOD fluid had seemed to have an adverse effect on the sperm biological function. But, this study showed that PCOD fluid had no different effect on sperm motility with normal follicular fluid.

수두 생바이러스 백신과 같은 생물의약품은 다양한 물질이 복합적으로 구성되어 있어 단순한 물리·화학적 분석방법만으로는 그 특성을 규명할 수 없다. 따라서 이러한 생물의약품의 품질을 평가하기 위해서는 표준품이 필수적이다. 2002년과 2003년에 제조 및 확립한 1차 국가표준품의 재고량 소진 및 역가 감소에 따라 식품의약품안전평가원에서는 수두 생바이러스 백신의 2차 국가표준품을 확립하기 위하여 2008년 용역연구사업을 통해 국내의 수두 생바이러스 백신 제조회사에서 표준품 후보물질을 제조하였으며, 국가표준품후보물질의 역가산정을 위하여 국내 제조사 및 식품의약품안전평가원에서 공동연구를 수행하였다. 국내제조사를 포함한 3개의 공동연구 시험소에서 7회 이상의 반복시험을 수행하여 얻은 공동연구 결과를 통계학적으로 분석한 결과 3곳의 공동연구 시험소의 통합역가에 대한 변이계수 (coefficient variation, CV)는 1.24%로 각 시험소간의 기하평균 (GMT) 변동 수준이 매우 낮음을 확인할 수 있었다. 또한, 수두 생바이러스 백신의 2차 국가표준품의 표시역가는 4.26 log10 PFU/0.5 mL로 산정하였다. Biological products, such as live varicella vaccine, are composed of biological substances derived from biological organisms. It is very difficult to identify these biologics’ characteristics by analysis of simple physical and chemical methods alone. So the reference material is essential in order to evaluate the quality of bilogics. The 1’st national standard for varicella live vaccine was manufactured, established in 2002 and 2003, and have been used for the manufacturer’s quality control and national lot release since then. As the lack of its availability and the decrease of its stability, this study was initiated by National Institute of Food and Drug Safety Evaluation (NiFDS) in 2008 to manufacture and establish the 2nd national standard for varicella live vaccine. The candidate material was manufactured from one of domestic manufacterers and the joint research of the NiFDS and manufacturers of varicella live vaccine was conducted to estimate of the reliable virus content. In the collaborative study, 3 laboratories including NiFDS performed the virus content test more than 7 times and all assay results were statistically analyzed. The mean coefficient of variation (CV) was 1.24%, and the geometric mean titre (GMT) variation range of each laboratory was low. On the basis of the results of this study, the candidate material of 2nd national standard for varicella live vaccine was assigned a potency of 4.26 log10 pfu/0.5 mL, when reconstituted in 0.7 mL.

The fashion market focuses on consumers and maximizes consumers` satisfaction. The fashion market has been segmented to better satisfy the variety of consumer group. Although market segmentation has been studied, efficiency and effectiveness of market segmentation continuously bring problems. Also, problems of prediction about real consumer behavior, and efficiency and effectiveness of standards are pointed out. The purpose of this study is to determine the most important variables for dividing fashion product buyers. This study was designed as qualitative study and in-depth interview was conducted. The in-depth interview was conducted with five experts in fashion intelligence agency. In-depth interview was completed by an analytic induction and an investigator triangulation. Questions were about characteristics, demographic characteristics, important factors and fashion buying relationship, and interests of current clothing shoppers. The results of qualitative research demonstrated that clothing shoppers, with their valuable consumption and selective buying behaviors, seek differentiated products. They also long for high quality apparel for its price, because of their valuable consumption and price centered tendency. They illustrated active sides, such as enthusiastic information searching and emotional or experiential consumption, rather than attitudinal sides. The variables for dividing fashion product buyers included: "innovative seeking", "symbolic seeking", "personalized seeking", "quality-seeking", "selective seeking", "price-seeking", "utility-seeking", "hedonic seeking", "sensitive seeking", "brand-seeking", "digital seeking", "information-seeking", and "eco-seeking".
