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>

Electronic Structure Study of Zr_(0.86)Y_(0.14)O_(2)

Jeon, Y. 전주대학교 공학기술종합연구소 2002 전주대학교 공학기술종합연구소 학술논문집 Vol.8 No.1

Zr L_(2,3) x-ray absorption spectroscopy (XAS) measurements on pure ZrO₂ and Y-stabilized cubic zirconia, Zr_(0.86)Y_(0.14)O₂, are reported. Detailed comparison of the L_(2,3) "white line" features on the two compounds evidences the increase of Zr d-orbital charge upon Y-substitution. This is consistent with the proximity of O-vacancies to Zr defect-sites in the Y-substituted material. The XAS based estimate of the induced defect Zr d-charge is found to be consistent with the proposed O-vacancy model.

Choi, S.G.,Bae, M.S.,Lee, E.S.,Kim, S.O.,Kim, B.K.,Yang, J.H.,Jeon, C.E.,Kim, H.H.,Hwang, Y.J.,Lee, E.S.,Kim, D.Y. Asian Australasian Association of Animal Productio 2009 Animal Bioscience Vol.22 No.8

The separation of X and Y chromosome-bearing sperm is of use in many aspects of livestock maintenance. In this study, we sought to determine the difference in DNA content between X- and Y-bearing sperm, separate sperm into X- and Y-enriched pools, and assess the efficacy of sorting. Sperm collected from Duroc and miniature pigs were stained with 20.8 $\mu{M}$ Hoechst 33342 and analyzed using a high-speed cell sorter. Measurement of the fluorescence intensity of stained sperm nuclei revealed that the X-bearing sperm of Duroc and miniature pigs respectively contain 2.75% and 2.88% more DNA than Y-bearing sperm. In total, 50.18% of the sperm were assigned to the X-sorted sample and 49.82% was assigned to the Y-sorted sample for Duroc pigs. For miniature pigs, the Xsorted sample represented 50.19% of the population and the Y-sorted represented 49.81% of the population. Duplex PCR was used to evaluate accuracy of sorting. A fast and reliable method for porcine sexing was developed through amplification of the sex-determining region of the Y chromosome gene (SRY). Oligonucleotide primers were designed to amplify the conserved porcine SRY high motility group (HMG) box sequence motif. We found that the primer pair designed in this study was 1.46 times more specific than previously reported primers. Thus, this study shows that the present method can be applied in porcine breeding programs to facilitate manipulation of the sex ratio of offspring and to achieve precise sexing of porcine offspring by amplification of the HMG box of the SRY gene.

Various field situations which have to be considered during CP design are summarized. Various protection criteria are explained in detail. Emphasis is put on the applicabilty and limit of each criteria in order to help people to select appropriate criteria. Finally, overprotection problem of some metals are explained.

The ameliorating effect of 1-palmitoyl-2-linoleoyl-3-acetylglycerol on scopolamine-induced memory impairment via acetylcholinesterase inhibition and LTP activation

Jeon, S.J.,Kim, B.,Park, H.J.,Zhang, J.,Kwon, Y.,Kim, D.H.,Ryu, J.H. Elsevier/North-Holland Biomedical Press 2017 Behavioural brain research Vol.324 No.-

In the present study, we investigated whether 1-palmitoyl-2-linoleoyl-3-acetylglycerol (PLAG), a component of antlers of Cervus nippon Temminck, would have memory-ameliorating properties against cholinergic blockade-induced memory impairment in mice. In the passive avoidance task to investigate the effects of PLAG on long-term memory, PLAG (10mg/kg, p.o.) administration ameliorated scopolamine-induced memory impairment. PLAG also reversed the impairments of working memory in the Y-maze task and spatial memory as shown in the Morris water maze. To identify the mechanism of the memory-ameliorating effect of PLAG, acetylcholinesterase (AChE) inhibition assay and the Western blot analysis were conducted. In the AChE inhibition assay, PLAG inhibited the AChE activity in mice and PLAG increased the expression levels of phosphorylated CaMKII, ERK, and CREB in the hippocampus. Additionally, long-term potentiation (LTP) of synaptic strength occurred by PLAG treatment in the hippocampal cultures. Overall, the present study suggests that PLAG reversed memory deficits in an animal model and that it affects biochemical pathways related to learning and memory.

We studied relationship among body image and self esteem and depression with using Spearman Correlation and analysised the differences between male and female groups with using T-test. This is the result of our research. 1. ale show higher BCS and BET scores than women. Between male and female, self-esteem have no big differences. And female is more depressive than male. 2. he two elements that body image and depression are in inverse proportion to each other in both male and female university students. 3. The two elements that self-esteem and depression are in inverse proportion to each other in both male and female university students. 4. The two elements that body image and self-esteem are in inverse proportion to each other in both male and female university students. And male have high correlation between BCS and BET, BCS and self-esteem, self-esteem and depression tha female. On the other hand, female have high correlation between BET and self-esteem, BET and depression In short, both male and female have correlation between body image, self-esteem and depression. Especially, between self-esteem snd depression have high correlation. In body image, especially female have high correlation between BET and depression. Finally we found the fact that female is more sensitively react than male about appearance.

RE³⁺ (RE³⁺ = Tm³⁺, Tb³⁺ and Sm³⁺) ions activated Y₆WO₁₂ phosphors: Synthesis, photoluminescence, cathodoluminescence and thermal stability

Bharat, L.K.,Jeon, Y.I.,Yu, J.S. Elsevier Sequoia 2016 JOURNAL OF ALLOYS AND COMPOUNDS Vol.685 No.-

The Y<SUB>6</SUB>WO<SUB>12</SUB> double oxide materials doped individually with rare-earth ions of Tm<SUP>3+</SUP>, Tb<SUP>3+</SUP> and Sm<SUP>3+</SUP> were prepared by a sol-gel method using citric acid as a complexing agent. The morphology of the prepared samples was studied using transmission electron microscope images and the crystallinity of the sample was confirmed by selective area electron diffraction patterns. The phase of the synthesized samples was analyzed by X-ray diffraction patterns and the optical properties were studied with photoluminescence (PL) and cathodoluminescence (CL) spectra. The emissions from the doped samples exhibited their respective colors both spectrally and to the naked eye under ultraviolet light excitation. Both PL and CL emission spectra showed the same results except the variation in the intensity of emission peaks. The activation energies calculated from the temperature-dependent PL spectra showed good thermal stability of the materials. The Commission International de I'Eclairage chromaticity coordinates calculated from the emission spectra were comparable to the standard phosphor used for lighting or imaging devices.

In this study, we investigated how much job-satisfaction and self leadership nurses have. And making use of self leadership, we hope to enhance job- satisfaction and develop nurse organization. To find out the relationship between nurse's self leadership and Job-satisfaction, we carried out a sample survey : The subjects of our study are 150 nurses being in offices(hospitals) at the two university hospitals and three general hospitals in Seoul or Keong-gi province. Nurses agreed with and understood the purpose of our study. For analyzing the result, we used ANOVA of SPSS 14.0. The main results of our study are as follows : According to characteristic of subjects, level of self leadership has a meaningful difference statistically according to marriage, religion, department career, position. As for the marriage, the level of self leadership of the married are higher((F=19.95, p= .000) than the unmarried. . Level of self leadership perceived by subjects is an average 3.50 point. An average points of each factors are as follows : Self-compensation is 3.75 point, rehearsal is 3.57 point, self-expectation is 3.55 point, goal-setting is 3.53 point, self-criticism is 3.31 point, constructive thinking is 3.27 point. The total average is 62.9 point to 90 full marks. Level of self job-satisfaction perceived by subjects is an average 2.98 point to 5 full marks. Level of self job-satisfaction perceived by subjects is an average 2.98 point to 5 full marks. An average points of each factors are as follows : Interrelation is 3.42 point, interrelation between doctors and nurses is 3.35 point, job demand is 3.10 point, administration is 3.02 point, a professional position is 2.94 point, self control is 2.84 point, payment is 2.44 point. A coefficient of co-relation of self leadership and self job-satisfaction is .406 point, a meaning probability is .000 point and they seem to have a close interrelation. Rehearsal among factors of self leadership has the most interrelation with payment of self job-satisfaction. A professional position of self job-satisfaction has the most interrelation with self expectation(r= .314, p= .000). A job demand has the most interrelation with constructive thinking(r= .272, p= .001). A interaction has the most interrelation with self expectation(r= .272. p= .000). A administration has the most interrelation with constructive thinking(r= .411, p= .000). An interrelation between doctors and nurses has the most interrelation with self expectation(r= .385, p= .000). Our study shows there is a close relation between self leadership and job-satisfaction. Especially, self expectation and constructive thinking, the factor of self leadership, appear to affect the nurse's job-satisfaction. It appears that nurses feel to have a intensive job-satisfaction, having positive self leadership, a sense of purpose, and constructive thought. Thus, we need to steadily study self leadership, self control, and internal motivation as a new paradigm focused on self-control and internal motivation for their self-developments and advancement of nurses' organizations.

Eclalbasaponin II Ameliorates the Cognitive Impairment Induced by Cholinergic Blockade in Mice

Jung, W. Y.,Kim, H.,Jeon, S. J.,Park, H. J.,Choi, H. J.,Kim, N. J.,Kim, D. H.,Jang, D. S.,Ryu, J. H. Springer Science + Business Media 2018 Neurochem Res Vol.43 No.2

<P>Eclalbasaponin II derived from Eclipta prostrata L. (Asteraceae) has been reported to have anti-fibrotic, anti-bacterial and autophagic activities, but its effect on cognitive function has not been investigated. We studied the effect of eclalbasaponin II on cholinergic blockade-induced memory impairment in mice using the passive avoidance, Y-maze, and Morris water maze tasks. Eclalbasaponin II (10 or 20 mg/kg, p.o.) significantly ameliorated the cognitive dysfunction induced by scopolamine in the passive avoidance, Y-maze, and the Morris water maze tasks. To identify the mechanism of the memory-ameliorating effect of eclalbasaponin II, acetylcholinesterase (AChE) activity assay, Western blot analysis and electrophysiology were conducted. Eclalbasaponin II inhibited the AChE activity in ex vivo study, and the administration of eclalbasaponin II and its metabolite, echinocystic acid, increased the phosphorylation levels of memory-related signaling molecules, including protein kinase B (Akt) and glycogen synthase kinase-3 beta (GSK-3 beta), in the hippocampus. Although eclalbasaponin II did not affect hippocampal long term potentiation (LTP), echinocystic acid significantly enhanced hippocampal LTP formation (30 mu M). These results suggest that eclalbasaponin II ameliorates cholinergic blockade-induced cognitive impairment via AChE inhibition, LTP formation and the activation of Akt-GSK-3 beta signaling, and that eclalbasaponin II may be a useful to treat cognitive impairment derived from cholinergic dysfunction.</P>
