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.

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.

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.

김연희,손미예,성낙주,Kim Yeon-Hee,Shon Mi-Yae,Sung Nak-Ju 한국생명과학회 2004 생명과학회지 Vol.14 No.6

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.

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.

식물체 구성성분의 하나인 hemicellulose의 대부분을 차지하는 xylan은 농산 폐기물 또는 목재 성분의 약 30%를 차지하는 풍부한 자원물질이다. 이러한 xylan을 효과적으로 분해하기 위해 Bacillus에서 발현시킨 재조합 endoxylanase를 이용하여 기능성 식품소재인 xylooligosaccharide의 최적 생산 조건을 조사하였다. B. subtilis 재조합 균주 DB431/pJHKJ4를 이용한 발효조 회분배양 결과, endoxylanse의 총활성은 857 unit/ml이며, 대부분이 세포밖으로 분비됨을 알 수 있었고, 분비효율은 92%로 나타났다. 재조합 endoxylanase를 이용하여 xylan으로부터 xylooligosaccharide 생성을 위한 최적 반응조건을 검토한 결과, xylooligosaccharide 생산을 위한 기질로는 birchwood xylan이 적합함을 알 수 있었고, 4%의 xylan 농도에서 가장 많은 xylooligosaccharide을 생산하며, xylobiose와 xylotriose가 주생성물임을 알았다. 효소의 농도와 반응시간의 영향은 10 unit의 endoxylanase를 첨가하여 1시간 반응시켰을 때 가장 많은 양의 xylooligosaccharide을 생산할 수 있었고, 반응온도는 40~50℃가 적합함을 알았다. 결론적으로 재조합 endoxylanase을 이용한 xylooligosaccharide생성에는 10 unit endoxylanase과 4% birchwood xylan을 기질로 이용하여 50℃에서 1시간 반응시키는 것이 최적반응 조건임을 알았다. Xylan is a major hemicellulose component of the cell walls of monocots and hardwood, representing up to 30% of the dry weight of these plants. To efficiently hydrolyze xylan, the endoxylanase gene from Bacillus sp. was expressed in B. subtilis DB431 by introducing the plasmid pJHKJ4. The total activity of the recombinant endoxylanase reached about 857 unit/ml by batch fermentation of B. subtilis DB431/pJHKJ4 in LB maltose medium. The majority (>92%) of endoxylanase was efficiently secreted into the culture medium. The recombinant endoxylanase hydrolyzed more the birchwood xylan efficiently than the other xylans. When 4% concentration of xylan was used, the highest production of xylooligosaccharide was observed, and xylobiose and xylotriose were the major products. Optimal amount of enzyme and reaction time for producing xylooligosaccharide were found to be 10 unit and 1 hr, respectively. In addition, the temperature of 40℃~50℃ gave the highest production of xylooligosaccharide. Consequently, the optimized conditions for the production of xylooligosaccharide through the hydrolysis of xylan were determined as follows: 10 unit endoxylanase, 50℃, 4% birch-wood xylan, 1 hr reaction.
