This study was conducted to investigate the effectiveness of a nonviolent communication program on nurse's interpersonal competence, job stress and spiritual wellness. This study was a inequality similar to the control group experimental design study of repeated measurements before and after. The data for this study were collected from June 1 to October 20, 2013 from 29 clinical nurses. The self-administered questionnaires used consisted of questions regarding general characteristics, interpersonal competence, job stress and spiritual wellness. The results were: 1. For interpersonal competence, the interaction between time and group was significant (F = 7.726, p = 0.002). 2. For job stress analysis, the interaction between time and group was not significant (F = 0.142, p = 0.851). 3. For spiritual wellness, the interaction between time and group was significant (F = 31.355, p < .001). These results suggest that the nonviolent communication program had a positive effect on rejected clinical nurse's interpersonal competence and spiritual wellness, but not on job stress. A follow-up replication study will be necessary.

The 26S proteasome is a 2-MDa complex with a central role in protein turn over. The 26S proteasome is comprised of one 20S core particle and two 19S regulatory particles (RPs). The RPN12a protein, a non-ATPase subunit of the 19S RP, was previously shown to be involved in cytokinin signaling in Arabidopsis. To further investigate cellular roles of RPN12a, RNAi transgenic plants of RPN12a were constructed. As expected, the 35S:RNAi-RPN12a plants showed cytokinin signaling defective phenotypes, including abnormal formation of leaves and inflorescences. Furthermore, RNAi knock-down transgenic plants exhibited additional unique phenotypes, including concave and heart-shape cotyledons, triple cotyledons, irregular and clustered guard cells, and defects in phyllotaxy, all of which are typical for defective cytokinin signaling. We next examined the mRNA level of cytokinin signaling components, including type-A ARRs, type-B ARRs, and CRFs. The expression of type-A ARRs, encoding negative regulators of cytokinin signaling, was markedly reduced in 35S:RNAi-RPN12a transgenic plants relative to that in wild type plants, while type-B ARRs and CRFs were unaffected. Our results also indicate that in vivo stability of the ARR5 protein, a negative regulator of cytokinin signaling, is mediated by the 26S proteasome complex. These results suggest that RPN12a participates in feedback inhibitory mechanism of cytokinin signaling through modulation of the abundance of ARR5 protein in Arabidopsis.

Activity-guided fractionation of the ethanol extract of the whole plant from Solanum lyratum resulted in the isolation of a new pregnane derivative glycoside, 16-dehydropregnenolone 3-O-${\alpha}$-L-rhamnopyranosyl-($1{\to}2$)-${\beta}$-D-glucopyranosid uronic acid (2), as well as other six known compounds: 16-dehydropregnenolone (1), allopregenolone (3), protocatechuic acid (4), vanillic acid (5), caffeic acid (6), and scopoletin (7). The structures of the isolated compounds were elucidated on the basis of their spectral data and chemical evidences. Compounds 1, 3, 4 were isolated for the first time from this plant. Cytotoxic activities of the isolated compounds were evaluated. Compound 1 exhibited significant cytotoxic activity against A375-S2, HeLa, SGC-7901, and Bel-7402 with $IC_{50}$ values of $13.1{\pm}0.9,\;21.5{\pm}1.0,\;40.2{\pm}0.7$, and $49.8{\pm}1.2\;{\mu}g/mL$, respectively.

A direct and precise explanation of soybean resistance to soybean cyst nematode will be possible only when the individual gene(s) involved in the resistance are tagged. This study was conducted, (1) to identify and localize quantitative trait loci for resistance to soybean cyst nematode race 14 on RAPD map, (2) to identify the magnitude and mode of inheritance for each quantitative trait loci, and (3) to identify the best combinations of quantitative trait loci for resistance to soybean cyst nematode race 14. Thirty markers (29 RAPD and 1 RFLP) showed significant association with resistance to soybean cyst nematode race 14. From MAPMAKER/QTL analysis, we identified two regions (linkage group C-7 and linkage group C-9) for resistance to soybean cyst nematode .ace 14. The first quantitative trait loci that was localized at 6.0 cM from $H06^1$ on linkage group C-7 showed a dominant inheritance mode. However, we can not exclude the possibility of additive inheritance mode. The second quantitative trait loci that was localized between $B15^2$ and $E01^1$ on linkage group C-9 also showed a dominant mode of inheritance. One pair of flanking markers ($H06^1$ and $H06^2$) and B15$^2$ were used for multiple regression analysis. Marker combination that included 2 markers, $B15^2$ and $H06^1$, explained the highest total variance (22.9%) for resistance to soybean cyst nematode race 14. Further localization of genes for resistance to soybean cyst nematode race 14 and examination of interaction between quantitative trait loci will accelerate the exploitation of resistance to soybean cyst nematode.

Plant growth and variegated leaf color changes of three leaf variegated Sedum spectabile varieties 'Variegatum', 'Frosty Morn', red colored 'Washfield Ruby', and one Sedum lineare variety 'Variegatum' and Sedum sarmentosum under three levels of shading conditions were examined for leaf ornamental value improvement. Shading levels were 40%($1,500{\mu}mol{\cdot}m-^2{\cdot}s-^1$), 70%($750{\mu}mol{\cdot}m-^2{\cdot}s-^1$) and 85%($375{\mu}mol{\cdot}m-^2{\cdot}s-^1$). Improvements of leaf ornamental value of 'Variegatum' 'Frosty Morn' and 'Washfield Ruby' were observed at 40% shading level and plant heights and leaf sizes were also increased. Plant height of S.sarmentosum were shorten under direct sun light condition and leaf color changed to greenish yellow(RHS143B) but deep green color(RHS144A) was observed under shading conditions. Endurance of S.sarmentosum was stronger than other species and leaf ornamental values remained well at 70% shading level. Leaf width of S.lineare 'Variegatum' were not changed under shading conditions but leaf length was increased. Leaf color was Deep green color was greenish yellow under direct sun light but deepest green color was observed at 85% shading level. Consider all ornamental value criteria, best shading conditions for S.lineare 'Variegatum' were ranged 40% to 70%.

Xiaoshuan Zaizao Wan (XZW) has been used in China to improve hemiplegia, deviation of eye and mouth, and dysphasia due to cerebral thrombosis. To characterize pharmacological actions of XZW, we evaluated its effects on neuronal cell damage induced in primary cultured rat cortical cells by various oxidative insults, glutamate or N-methyl-D-aspartate (NMDA), and $\beta$-amyloid fragment ($A_{\beta(25-35)}$). XZW was found to inhibit the oxidative neuronal damage induced by $H_2O_2$, xanthine/xanthine oxidase, or $Fe^{2+}$/ascorbic acid. It also attenuated the excitotoxic damage induced by glutamate or NMDA. The NMDA-induced neurotoxicity was more effectively inhibited than the glutamate-induced toxicity. In addition, we found that XZW protected neurons against the $A_{\beta(25-35)}$-induced toxicity. Moreover; XZW exhibited dramatic inhibition of lipid peroxidation in rat brain homogenates and mild 1,1-diphenyl-2-picrylhydrazyl radical scavenging activity. Taken together; these results demonstrate that XZW exerts neuroprotective effects against oxidative, excitotoxic, or $A_{\beta(25-35)}$-induced neuronal damage. These findings may provide pharmacological basis for its clinical usage treating the sequelae caused by cerebral thrombosis. Furthermore, XZW may exert beneficial effects on Alzheimer's disease and other oxidative stress-related neurodegenerative disorders.

Purpose: This study was conducted to evaluate the efficacy of a community-based follow-up program on parenting stress, parenting efficacy, and coping among parents with premature infants. Methods: A non-equivalent control group pre-post quasi-experimental design was used. This program consisted of structured home visits and self-help group meetings for 6 months. The experimental group (n=29) received visits by an experienced neonatal intensive care unit (NICU) nurse and the control group (n=27) was visited by a visiting nurse. Data were analyzed using the χ² test, t-test, and analysis of covariance. Results: Parents' coping behavior significantly differed in the experimental group compared to the control group (t=3.14, p=.003). In particular, coping subscale I, for maintaining the family situation (t=2.63, p=.011), and subscale III, for understanding the infant's medical situation (t=4.30, p<.001), showed significant differences in the experimental group. There were no significant between-group differences in parenting stress or parenting efficacy. Conclusion: The findings of this study suggest that home visits by an experienced NICU nurse provided through a community-based follow-up program were an effective intervention to improve coping behavior among parents with premature infants.

The next local election for Jeollabuk-do will be held in 2010. In preparation for this, we conducted a study to observe whether or not if minute regionalism occurred during the fourth "Nationally coordinated local election" which was held on May 31st in 2006. This study is based on Jeollabuk-do provincial governor election data. For this, we introduced a RS index which is used to measure how evenly each candidate for governor of the province received votes, and chi-statistics that measure each candidate's local intimacy. Further more, we checked out whether minute regionalism occurred or not by putting to practical use correspondence analysis. As a result, we could confirm that minute regionalism occurred to a few candidates. After reviewing many measurements, we found that a RS index's validity is not high.

The eyes can register color oscillations and that colors have an effect on the psyche. Human is constantly surrounded by an immense range of vibrations to which he must react and respound. And the skin can be compared to an antenna which amplifies information received from the outside and then passes it on to the inside. Therefore the art of many medicines make use of the skin as a medium of treatment. Peter mandel discovered centers, or zones, on the human body, which represent or correspond to the three primary colors(red, blue and yellow). And he came across to the four temperaments(or humors) and their respective colors, which consist of the primary colors with the addition of green.
