Purpose: This study was conducted to investigate the relationship of burn out, emotional labor and self-efficacy in nurses, and to identify predictors of burnout. Method: The participants were 268 nurses working in C university hospital in G city. Data were collected from May 1 to May 31, 2010, and analyzed using SPSS/WIN 12.0. Results: The mean score per item for burnout was 3.13, the mean emotional labor score was 3.15, and the mean of self-efficacy score was 3.42. Burnout showed negative correlation with self-efficacy (r=-.339, p=.000), and showed positive correlation with emotional labor (r=.511, p=.000). Variables that predicted burnout were emotional labor, self-efficacy, gender, number of assigned patient per duty (37.8%). Conclusion: The findings of this study indicate a need to develop programs for nurses to increase self-efficacy and to control the emotion, and the need for further studies to examine causal relationship among burn out, emotional labor and self-efficacy.

Purpose: The improvement of the social security system can greatly affect residents' future uncertainty, and it is important to study the relationship between public pensions and household consumption. Research design, data and methodology: Using the 2018 China Household Panel Survey (CFPS) data, the instrumental variable method is used to analyze the impact of pension insurance on urban residents' consumption. Results: The results of the study show that there are differences in the impact of three different pension insurance systems on household consumption. The pension insurance for public sector significantly boosts household consumption, and having a pension insurance for public sector can increase household consumption by 7.7%. The pension insurance for enterprise employee will reduce household consumption, but this is only significant for urban households. The pension insurance for urban and rural residents has a negative impact on household consumption. For the 16- to 39-year-old group, having a pension insurance for urban and rural residents will reduce household consumption by 5.7%. At the same time, household income, assets, scale, and education level will positively stimulate household consumption. Conclusions: The study reveals varying impacts among different pension types, highlighting the need for optimizing social security schemes to incentivize higher consumption rates.

Zeng, Ya-Wen,Du, Juan,Pu, Xiao-Ying,Yang, Jia-Zhen,Yang, Tao,Yang, Shu-Ming,Yang, Xiao-Meng Asian Pacific Journal of Cancer Prevention 2015 Asian Pacific journal of cancer prevention Vol.16 No.6

Cancer is the leading cause of death around the world. Anticancer activities from many functional food sources have been reported in years, but correlation between cancer prevalence and types of food with anticancer activities from crop origin center in the world as well as food source with human migration are unclear. Hunger from food shortage is the cause of early human evolution from Africa to Asia and later into Eurasia. The richest functional foods are found in crop origin centers, housing about 70% in the world populations. Crop origin centers have lower cancer incidence and mortality in the world, especially Central Asia, Middle East, Southwest China, India and Ethiopia. Asia and Africa with the richest anticancer crops is not only the most important evolution base of humans and origin center of anticancer functional crop, but also is the lowest mortality and incidence of cancers in the world. Cancer prevention of early human migrations was associated with functional foods from crop origin centers, especially Asia with four centers and one subcenter of crop origin, accounting for 58% of the world population. These results reveal that coevolution between human's anticancer activities associated with functional foods for crop origin centers, especially in Asia and Africa.

A large number of extracts from the medicinal plants growing in Vietnam were screened for their in vitro antitrypanosomal activity toward Trypanosoma brucei. Among them, eighty-seven extracts showed the significant antitrypanosomal activity. Especially, the extracts from Neocinnamomum delavayi, Mallotus cuneatus, and Mallotus api exhibited the highest inhibitory activity against T. brucei (IC50: 0.16, 0.49 and <0.05 μg/mL). Cephalotaxus mannii, Pittosporum floribundum, Cleistanthus aff. annamensis, Wendlangia tinctoria subsp. barbatus, Maesa parvifolia, Alpinia malaccensis, Glycosmis scandens, Mallotus yunnanensis, and Maesa sp also presented potent T. brucei inhibitory activity, with IC50 value ranging from 1.14 to 4.98 μg/mL. Based on these results of screening study, the extracts from N. delavayi, M. cuneatus, M. api, C. mannii, P. floribundum, C. aff. annamensis, W. tinctoria subsp. barbatus, M. parvifolia, A. malaccensis, G. scandens, M. yunnanensis, and Mallotus sp. might be the rich source of antitrypanosomal components. Therefore, further phytochemistry and pharmacological study of these medicinal plants should be researched and developed.

An Efficient Binarization Method for Vehicle License Plate Character Recognition

Yang, Xue-Ya,Kim, Kyung-Lok,Hwang, Byung-Kon Korea Multimedia Society 2008 멀티미디어학회논문지 Vol.11 No.12

In this paper, to overcome the failure of binarization for the characters suffered from low contrast and non-uniform illumination in license plate character recognition system, we improved the binarization method by combining local thresholding with global thresholding and edge detection. Firstly, apply the local thresholding method to locate the characters in the license plate image and then get the threshold value for the character based on edge detector. This method solves the problem of local low contrast and non-uniform illumination. Finally, back-propagation Neural Network is selected as a powerful tool to perform the recognition process. The results of the experiments i1lustrate that the proposed binarization method works well and the selected classifier saves the processing time. Besides, the character recognition system performed better recognition accuracy 95.7%, and the recognition speed is controlled within 0.3 seconds.

Cloning and Characterization of a Na+/H+ Antiporter Gene of the Moderately Halophilic Bacterium Halobacillus aidingensis AD-6T

Ya Jie Zou,Li Fu Yang,Lei Wang,Su Sheng Yang 한국미생물학회 2008 The journal of microbiology Vol.46 No.4

A gene encoding a Na+/H+ antiporter was obtained from the genome of Halobacillus aidingensis AD-6T, which was sequenced and designated as nhaH. The deduced amino acid sequence of the gene was 91% identical to the NhaH of H. dabanensis, and shared 54% identity with the NhaG of Bacillus subtilis. The cloned gene enable the Escherichia coli KNabc cell, which lack all of the major Na+/H+ antiporters, to grow in medium containing 0.2 M NaCl or 10 mM LiCl. The nhaH gene was predicted to encode a 43.5 kDa protein (403 amino acid residues) with 11 putative transmembrane regions. Everted membrane vesicles prepared from E. coli KNabc cells carrying NhaH exhibited Na+/H+ as well as Li+/H+ antiporter activity, which was pH-dependent with the highest activity at pH 8.0, and no K+ /H+ antiporter activity was detected. The deletion of hydrophilic C-terminal amino acid residues showed that the short C-terminal tail was vital for Na+/H+ antiporter activity.

Effects of different biochar amendments on carbon loss and leachate characterization from an agricultural soil

Yang, Xing Ya,Chang, Kwang-Hyeon,Kim, You Jin,Zhang, Jin,Yoo, Gayoung Elsevier 2019 CHEMOSPHERE - Vol.226 No.-

<P><B>Abstract</B></P> <P>Selection of an appropriate biochar as a soil amendment requires a thorough investigation of the effects on soil ecosystems and adjacent water systems via leaching. Different biochar characteristics influence retention or leaching of different soil and biochar components. A lab lysimeter study was conducted to investigate carbon (C) balance and leachate quality with biochar additions. Biochar made from wood pellets (WP) and sewage sludge (SS) produced at 400 °C (WP400 and SS400) and 700 °C (WP700 and SS700), respectively, were applied to silt loam soil at an application rate of 4%. Fluorescence excitation-emission spectrophotometry (EEMs) was utilized to understand the compositional changes in leachate dissolved organic carbon (DOC). Our results show that DOC contributed the largest portion of C leaching loss. The WP treatments increased DOC mass loss, but did not significantly change leachate DOC quality. SS400, in comparison, increased mass loss of DOC and SS700 decreased it probably due to its higher adsorptive capacity to DOC. Unlike WP treatments, SS treatments significantly changed leachate DOC quality. Chemical oxygen demand (COD) was reduced with SS400 and SS700 biochar additions, which is assumed to be related to SS biochar's high oxygen-containing surface functional groups. Reduction in total nitrogen (TN) leaching by WP700 and SS700 treatments might be related to the higher micropore surface area. Over all, our findings imply that changes in the different components of the leachate from biochar-amended soil are related to different biochar properties, such as labile matter content, total surface area, micropore volume and cation exchange capacity.</P> <P><B>Highlights</B></P> <P> <UL> <LI> DOC contributed the largest portion of C leaching loss from biochar added soils. </LI> <LI> Leachate properties of biochar addition were related to biochar characteristics. </LI> <LI> Wood pellet biochar increased DOC leaching but did not influence DOC quality. </LI> <LI> Sewage sludge biochar (700 °C) reduced COD/TN leaching and retained humic substances. </LI> </UL> </P>
