We conducted a cross‐sectional telephone survey for women who had obtained a National Cancer Screening Programme mammographic screening at general hospitals between May and October 2008. The present study included 2005 women in their forties. We performed multivariate linear regression using dependent variable as general satisfaction and independent variables as subscales of satisfaction, such as pre‐screening information transfer, staff interpersonal skills, physical surroundings and results reporting. Participants were stratified according to the result of their mammogram as negative or positive. Mean score of satisfaction was above 2.5 of 4 for all subscales. Women who received positive results were less satisfied with all of subscale factors. Staff interpersonal skills were the most important factor that contributed to general satisfaction. Future efforts such as staff training programme of communication/attitude skills, ensuring privacy and explanation of possible discomfort of the screening would be needed.</P>

Glycerol-fed microbial fuel cell with a co-culture of Shewanella oneidensis MR-1 and Klebsiella pneumonae J2B

Kim, C.,Song, Y. E.,Lee, C. R.,Jeon, B. H.,Kim, J. R. SPRINGER 2016 Journal of industrial microbiology & biotechnology Vol.43 No.10

<P>Glycerol is an attractive feedstock for bioenergy and bioconversion processes but its use in microbial fuel cells (MFCs) for electrical energy recovery has not been investigated extensively. This study compared the glycerol uptake and electricity generation of a co-culture of Shewanella oneidensis MR-1 and Klebsiella pneumonia J2B in a MFC with that of a single species inoculated counterpart. Glycerol was metabolized successfully in the co-culture MFC (MFC-J&M) with simultaneous electricity production but it was not utilized in the MR-1 only MFC (MFC-M). A current density of 10 mA/m(2) was obtained while acidic byproducts (lactate and acetate) were consumed in the co-culture MFC, whereas they are accumulated in the J2B-only MFC (MFC-J). MR-1 was distributed mainly on the electrode in MFC-J&M, whereas most of the J2B was observed in the suspension in the MFC-J reactor, indicating that the co-culture of both strains provides an ecological driving force for glycerol utilization using the electrode as an electron acceptor. This suggests that a co-culture MFC can be applied to electrical energy recovery from glycerol, which was previously known as a refractory substrate in a bioelectrochemical system.</P>

<P>A novel Gram-negative, aerobic, motile, short rod-shaped bacterium, designated J64T, was isolated from black sand collected from Soesoggak, Jeju Island, Korea. Cells grew at 4-37 degrees C, at pH 5.5-10.0 and with 0-10 % NaCl. The strain was found to be oxidase- and catalase-positive. Phylogenetic analyses showed that strain J64T belongs to the genus Pseudomonas, forming a monophyletic group with Pseudomonas pachastrellae, Pseudomonas pertucinogena and 'Pseudomonas denitrificans'. The 16S rRNA gene sequence similarity between strain J64T and type strains of all Pseudomonas species with validly published names was below 96.6 %. Low levels of DNA-DNA relatedness were found with respect to type strains of P. pachastrellae and P. pertucinogena, supporting the classification of strain J64T within a novel species of the genus Pseudomonas. Strain J64T contained C(18 : 1)omega7c (37.2 %), C(16 : 0) (20.4 %), summed feature 3 (17.4 %; comprising iso-C(15 : 0) 2-OH and/or C(16 : 1)omega7c) and C(12 : 0) (7.6 %) as major cellular fatty acids. On the basis of the phenotypic and phylogenetic data, strain J64T represents a novel species of the genus Pseudomonas, for which the name Pseudomonas sabulinigri sp. nov. is proposed. The type strain is J64T (=KCTC 22137T =JCM 14963T).</P>

Kim, K.-H.,Roh, S. W.,Chang, H.-W.,Nam, Y.-D.,Yoon, J.-H.,Jeon, C. O.,Oh, H.-M.,Bae, J.-W. Microbiology Society 2009 International journal of systematic and evolutiona Vol.59 No.1

<P>A novel Gram-positive, aerobic, short-rod-shaped bacterium, designated strain J112T, was isolated from black sand collected from Soesoggak, Jeju Island, Korea. The strain was found to be oxidase-negative and catalase-positive. Cells grew at 10-37 degrees C, at pH 5.5-8.0 and with 1-10 % NaCl. Growth occurred on marine agar but not on R2A or trypticase soy agar. A phylogenetic analysis based on 16S rRNA gene sequences showed that the strain belongs to the radiation of the genus Nocardioides. Strain J112T shared the highest 16S rRNA gene sequence similarities with Nocardioides marinisabuli SBS-12T (99.2 %), Nocardioides terrigena DS-17T (97.3 %), Nocardioides kribbensis KCTC 19038T (97.1 %) and type strains of other Nocardioides species with validly published names (<97 %). The DNA-DNA hybridization values between strain J112T and the three most closely related strains were low enough to justify the assignment of this strain to a novel species. On the basis of these phenotypic, phylogenetic and chemotaxonomic data, strain J112T represents a novel species of the genus Nocardioides, for which the name Nocardioides basaltis sp. nov. is proposed. The type strain is J112T (=KCTC 19365T=JCM 14945T).</P>

We investigated postpartum behaviors of sows and their litters. The aim of this study was to determine the behavioral recovery of sows and behavioral development of their piglets postpartum. Five multiparous sows(Landrace × Yorkshire) and their litters were studied over a period of 5 days postpartum. The litter size varied from 8 to 13 with a mean of 11.2 piglets. The behaviors of sows and their piglets were recorded using five CCD cameras, a multiplexer and a time lapsed VCR. The videotapes were scanned every 2 min to obtain an instantaneous behavioral sample. In the behaviors of sows, ?Lying ventrally? increased from 1h postpartum to 26g postpartum, then decreased gradually, and stabilized after 80h postpartum. ?Lying ventrally? decreased from 1h postpartum to 26h postpartum and stabilized after 80h postpartum. ?Standing, drinking and feeding? increased from 1h postpartum to 23h postpartum, then decreased gradually, and increased again from 60h postpartum. ?Sitting? increased from 1h postpartum to 46h postpartum and then decreased. In the behaviors of piglets, ?Lying? increased rapidly from 1h postpartum to 45h postpartum, and then was maintained at an almost constant level. ?Massaging and Suckling? decreased rapidly from 1h postpartum to 36g postpartum, and then was maintained at an almost constant level. ?Walking? increased from 1h postpartum to 21h postpartum, then decreased gradually. These results suggest that the behavioral recovery of the sow is almost completed at 80h postpartum and that the behavioral development of the piglet is almost completed at 45h postpartum.

Purpose: It is significant to improve the understanding and knowledge about hypertension, because self care is essential to those who are diagnosed hypertension. And if the elderly having hypertension could obtain required health-information via internet, it would help them control blood pressure. The purpose of this study was to know whether internet literacy would influence level of hypertension knowledge and self care to the subjects and to provide basic data which develops internet literacy for the elderly’ health promotion. Method: Data was collected from 249 elderly the subjects(aged 65 years or older) taking part in S, Y elderly municipal welfare center in Seoul. We used questionnaires composed of 10 questions about internet literacy, 20 questions about level of hypertension knowledge, and 24 questions about self care. Data was analyzed by using the following methods: descriptive statistics, t-test, ANOVA and Pearson Correaltion Coefficient. All statistical tests were performed by the SPSS version 18.0. Result: The test showed that gender, age, education level, monthly income, existence of available computer, period using internet and weekly time using internet were relevant to internet literacy of the elderly having hypertension. The internet literacy was not relevant to level of hypertension knowledge, but was relevant to self care. And level of hypertension knowledge was relevant to self care. Conclusion: It is needed to develop internet education program, considering background of the elderly. We suggest that the program should change cognition and attitude of the elderly. So the program provides not just mere education but motivation and will to encourage self care. When those considerations are attained, the program would be helpful to the elderly’s health promotion.
