<P>Virulent Escherichia coli strains have commonly been associated with diarrheal illness in humans and animals. Typical enteropathogenic Escherichia coli (EPEC) with intimin gene (eaeA) and E. coli adherence factor plasmid, or atypical EPEC with only eaeA have been implicated in human cases. In the present study, we investigated the prevalence of virulence-associated genes including eaeA in the E. coli strains isolated from cloacal specimens of 184 chicken flocks in 7 provinces in Korea between 2009 and 2010. When 7 virulence genes (VT1, VT2, LT, and ST for enterotoxigenic E. coli; eaeA and bfpA for enteropathogenic E. coli; and aggR for enteroaggregative E. coli) were screened by multiplex PCR, a total of 30 E. coli strains carrying only the eaeA gene were detected from 184 flocks that were identified as atypical enteropathogenic Escherichia coli (aEPEC). The aEPEC strains were analyzed by eae subtyping, phylogenetic grouping PCR, and serotyping. Twelve (40%) of 30 aEPEC strains possessed an eae-관 subtype, followed by 관 (30%), 관 (16.7%), and 관1 (13.3%). Eight (26.7%) of 30 aEPEC strains were designated into the phylogenetic group A. Two (6.7%) and 3 (10%) aEPEC strains were classified into the phylogenetic group B2 and D, respectively. A total of 15 (50%) aEPEC strains were serotyped to groups O24, O25, O26, O71, O80, O103, and O157, and the remaining strains were nontypeable. In analyzing the genetic diversity among the 30 aEPEC isolates by the pulsed-field gel electrophoresis method with XbaI-digestion, the pulsed-field gel electrophoresis profiling produced 20 different patterns, but isolates within the same group did not show clear geographic or breed relationships. Our data indicate that healthy chickens may constitute an important natural reservoir of aEPEC strains, and suggest that transmission to humans could not be excluded.</P>

Kwon, M.,Yoon, Y.,Cho, E.,Jung, Y.,Lee, B.C.,Paeng, K.J.,Kang, J.W. Elsevier Scientific Pub. Co 2012 Journal of hazardous materials Vol.227 No.-

The aim of this study is to evaluate the removal efficiency of iopromide using electron beam (E-beam) irradiation technology, and its degradation characteristics with hydroxyl radical (OH?) and hydrated electron (e<SUB>aq</SUB><SUP>-</SUP>). Studies are conducted with different initial concentrations of iopromide in pure water and in the presence of hydrogen peroxide, bicarbonate ion, or sulfite ion. E-beam absorbed dose of 19.6kGy was required to achieve 90% degradation of 100μM iopromide and the E-beam/H<SUB>2</SUB>O<SUB>2</SUB> system increased the removal efficiency by an amount of OH? generation. In the presence of OH? scavengers (10mM sulfite ion), the required dose for 90% removal of 100μM iopromide was only 0.9kGy. This greatly enhanced removal was achieved in the presence of OH? scavengers, which was rather unexpected and unlike the results obtained from most advanced oxidation process (AOP) experiments. The reasons for this enhancement can be explained by a kinetic study using the bimolecular rate constants of each reaction species. To explore the reaction scheme of iopromide with OH? or e<SUB>aq</SUB><SUP>-</SUP> and the percent of mineralization for the two reaction paths, the total organic carbon (TOC), released iodide, and intermediates were analyzed.

Purpose: The purpose of this study was to examine the correlation of alcohol use disorder, social support and depression of the college students. Method: In this descriptive design study, 334 university students were recruited through convenient sampling from October, 2015 to January, 2016. Questionnaires used for online Google docs were AUDIT-K(Alcohol Use Disorders Identification Test-Korea), MSPSS(Multidimensional Scale of Perceived Social Support) and SDS(Self - Rating Depression Scale). Data were analyzed with descriptive statistics, independent t-test, one way ANOVA with Scheffe's test, and Pearson’s coefficient using SPSS 22.0 program. Result: 230 students of the 334 college students(68.8%) were classified into alcohol use disorder group. There was a significant correlation between the degree of social support and depression among all participants(r=-.45, p=.000). However, there was no correlation between alcohol use disorder and depression(r=.23, p=.006) and between alcohol use disorder and social support(r=.02, p=.758). Conclusion: This study showed a relationship between social support and depression, not the alcohol use disorder. This result can be used as the basic data in nursing research about alcohol use disorder, social support and depression of college students. Also, Further researches are needed to examine the factors that affect alcohol use disorder of college students, as well as depression and social support.

Purpose: The purpose of this study is to obtain comprehensive understanding of Korean middle-age men's experience in their andropause. The findings of this study will provide supportive data for development of nursing interventions. Methods: This study is explored by hermeneutic phenomenological analytic method suggested by van Manen. Data was collected through in-depth interviews with 7 middle aged men between July and September, 2017. Before the interviews, preliminary questionnaire was preformed for all participants. Results: The analysis produced five themes: 'My body is getting weaker than before', 'A sense of despondency with current life', 'Regarding andropause not as much important as menopause', 'The obscurity of one's life about andropause', 'Cut off andropause from life'. Conclusion: This study explored Korean middle-age men's experience in their andropause. Although most participants experienced physical and psychological symptoms, they denied that they are andropause. Moreover, they lacked knowledge and showed attitude of indifference. In addition, Andropause is not as commonly recognized in the society of Korea. Even if they perceive it, they cannot reveal the fact and respond poorly. It brings up the necessity to provide proper information and education. A variety of nursing interventions are also required for the men for their physical or mental recovery and health care. Therefore, this study offers the deep understanding of the significance and nature of the experience in andropause. Furthermore, this study may put foundation for development in nursing care of studies of this subject.

The mortality and morbidity caused by injury and poisoning has been a major public health problem in Korea. this study was carried out to get information indispensable in developing prevention srategies peculiar to Korean rural area. In this study 444 people of 14 households, who are living in five rural villages of Chooncheon City, Kang-Won Province, were interviewed in accordance with structured questionaire by MPH students and teaching staff of School of Public Health SNU during the field training course of 1997 academic year. The results obtained are summarized as follows: 1. The age-standardized annual incidence rates of injury and poisoning per 100 persons surveyed were 19.8 in males and 14.1 in females. The difference between sex was not statistically significant. The age specific incidence rate generally revealed that the incidence increased as age advanced, suggesting vulnerability of aging to the accident. 2. The incidence rates of injuries and poisoning were higher among the people living in traditional Korean-style house than those living in others(a Westen-style house), the accident occurred more frequently in kitchen and toilet than other places within the house, and the differences in the incidence were statistically significant. 3. The places where most of injuries and poisonings occurred were road and cultivating area(27.5% each) among males, and cultivating area(42.5%), indoor and road(15.7% each) among females. 4. The occurrence of the injuries and poisoning were clustered in intensive farming season in males, whereas farmong season and winter in females. The injury and poisoning occurred more frequently in the afternoons of the day although the clustering of thd accidents by time showed different pattern by sex and type. 5. The laceration and stab wound were the most frequent nature of injuries in both males and females. On the other hand abrasion, organ damage and amputation were more frequent among males but concussion and fracture were more frequent among females. 6. Incidence rates of injuries and poisoning by cause were higher in traffic accidents and farming among males, though falls among females. The cause specific incidence rate by age was high in traffic accidents for 10-2 year age group(62.5%), and in falls for 30-59 year age group and the aged peole older than 60 years. 8. In the management pattern, 36 percents of the injuries and poisonings wer self-treated and the 30 percents of those received medical care in hospitals and clinics, the medical expenditure being over 100,000 won in 25% of injured and the duration of the treatment over 2 weeks in 46%. The results obtained indicate that organized community effort is urgently required to prevent injuries and poidsonings in rural area.

Purpose: The purpose of this study was to explore the differences among social comparison orientation, depression, and self-esteem by patterns of using Facebook among Facebook users’ in their 20s. Methods: The participants in this descriptive study were 332 Facebook users in their 20s. Data collection took place between August 21 and 27, 2014. Questionnaires were the Iowa–Netherlands Comparison Orientation Measure (revised), Center for Epidemiologic Studies Depression Scale, and Rosenberg Self-Esteem Scale. Data were statistically analyzed using t-tests and ANOVAs. Result: Each mean score of social comparison, depression, and self-esteem was 26.04±6.82, 31.39±8.99 and 38.05±6.19. Significant differences emerged between the degree of social comparison and the following Facebook usage variables: average single-connection time to Facebook (F=3.570, p=.007) and self-evaluation of Facebook usage behavior (F=6.203, p<.001). Conclusion: The results of this study suggested that Facebook users in their 20s who access Facebook for long periods and assess themselves as using it more often had a high score of comparison orientation. This result can be used in Nursing by developing the theoretical basis for education and campaign related to Facebook usage. In-depth studies are needed for research on the effect social comparison has on Facebook users and relationships between social comparison and emotions.

Purpose: This study aims to identify the correlation between perception of emotional dating violence and satisfaction of relationship of college students to provide objective data for college students to improve perception of emotional dating violence and satisfaction of relationship. Methods: Data was collect using questionaries between November 3rd to November 20th, 2018. Participants of this study were 110 male college students and 127 female college student who are currently attending universities aged 18 to 29 years old. Data were analyzed using average, standard deviation, t-test, ANOVA, and Pearson’s correlation using the SPSS 21.0 program. Result: The study has established the negative correlation between perception of emotional dating violence and satisfaction of relationship(R=-.587, p<.001). As the level of perception of emotion dating violence is lower, satisfaction of relationship is higher. The number of relationships recognized by oneself, experience of dating violence, and severity of dating violence also demonstrated significant difference in perception of emotional dating violence and satisfaction of relationship. Conclusion: The result of the study suggests that perception of emotional dating violence is negatively related to satisfaction of relationship. Furthermore, this study suggests that it is important to increasing perception of dating violence for healthier and better quality of relationships.
