Background: Previous studies for non-communicable disease cotrol, including cancer, have mostly relied on health literacy in adults. However, limited studies are available for adolescents. This study aimed to assess the status and determinants of health literacy in in-school adolescents in Guangdong, China. Materials and Methods: A total of 3,821 students aged 13-25 years were selected by multi-stage cluster sampling. After the questionnaire of health literacy was answered, the total scores for health knowledge (18 questions), skills (5 questions) and behaviors (14 questions) were determined. The total scores for health literacy and each subscale were recoded into adequate and inadequate subgroups, and logistic regression models were used to identify factors associated with each outcome variable. Results: The prevalence of adequate health literacy was 14.4%, and the prevalences for adequate knowledge, skills and behavior were 22.4%, 64.7% and 6.6%, respectively. Students coming from prestigious schools and having parents with higher education had higher odds of having adequate knowledge, skills and behaviors. Female students had higher odds of having adequate knowledge and behaviors. Students in grade 7-8 had higher odds of having adequate knowledge and skills. The health knowledge was positive associated with health skills (odds ratio [OR] =2.1, 95% confidence interval [CI] 1.7-2.5) and behaviors (OR=3.0, 95%CI 2.3-4.0), and health skills were positive associated with health behaviors (OR=2.6, 95%CI 1.8-3.8). Conclusions: Further efforts should be made to increase adolescents' health knowledge and behaviors, especially for low grade and male students in non-prestigious schools.

A series of new small molecules based on symmetric electron-acceptor of 1,3,4-oxadiazole moiety or its asymmetric isomerof 1,2,4-oxadiazole unit were successfully synthesized and applied to solution-processable blue phosphorescent organic lightemittingdiodes for the first time, and their thermal, photophysical, electrochemical properties and density functional theorycalculations were studied thoroughly. Due to the high triplet energy levels (ET, 2.82–2.85 eV), the energy from phosphorescentemitter of iridium(III) bis[(4,6-difluorophenyl)-pyridinate-N,C2′]picolinate (FIrpic) transfer to the host molecules couldbe effectively suppressed and thus assuring the emission of devices was all from FIrpic. In comparison with the para-modeconjugation in substitution of five-membered 1,3,4-oxadiazole in 134OXD, the meta-linkages of 1,2,4-isomer appending withtwo phenyl rings cause the worse conjugation degree and the electron delocalization as well as the lower electron-withdrawingability for the other 1,2,4-oxadiazole-based materials. Noting that the solution-processed device based on 134OXD containing1,3,4-oxadiazole units without extra vacuum thermal-deposited hole/exciton-blocking layer and electron-transportinglayer showed the highest maximum current efficiency (CEmax) of 8.75 cd/A due to the excellent charge transporting ability of134OXD, which far surpassed the similar devices based on other host materials containing 1,2,4-oxadiazole units. Moreover,the device based on 134OXD presented small efficiency roll-off with current efficiency (CE) of 6.26 cd/A at high brightnessup to 100 cd/m2. This work demonstrates different nitrogen and oxygen atom orientations of the oxadiazole-based hostmaterials produce major impact on the optoelectronic characteristics of the solution-processable devices.

The present study evaluated the potential neuroprotective effect and underlying mechanism of the total flavones extracted from Chrysanthemum morifolium (TFCM) against ischemia/reperfusion (I/R) injury. An animal model of cerebral ischemia was established by occluding the right middle cerebral artery for 90 minutes followed by reperfusion for 22 hours. The neurobehavioral scores, infarct area, and hemispheric edema were evaluated. The superoxide dismutase (SOD) activity, malondialdehyde (MDA) content, and reactive oxygen species (ROS) level in brain were also measured. The results showed that pretreatment with TFCM significantly decreased the neurological deficit scores, percentage of infarction, and brain edema and attenuated the decrease in SOD activity, the elevation of MDA content, and the generation of ROS. In isolated brain mitochondria, Ca2+-induced swelling was attenuated by pretreatment with TFCM, and this effect was antagonized by atractyloside. These results showed that pretreatment with TFCM provides significant protection against cerebral I/R injury in rats by, at least in part, its antioxidant action and consequent inhibition of mitochondrial swelling.

李白 賦 初探

예추이화(Ye Cui Hua) 한국중어중문학회 2017 中語中文學 Vol.0 No.68

As “The poetic genius(詩仙)”, Li Bai(李白)’s poems are widely read by later generations. Lots of scholars analyzed and appreciated his poems in detail. Under the shadow of his shining poems, neither his works of fu(賦) draw too much attention nor been researched. However, if we would like to study about Li Bai comprehensively, we should understand Li Bai not only as a poet, but also as a writer of fu. Only can we interpret Li Bai’s fu accurately, could we understand Li Bai as a writer of fu. Wang Qi, who is a scholar in Qing dynasty, collected Li Bai’s eight pieces of fu in 《Li Taibai Wenji(李太白文集)》of volume 1, including 〈Da peng fu(大鵬賦)〉, 〈Ni hen fu(擬恨賦)〉, 〈Xi yu chun fu(惜餘春賦)〉, 〈Chou yang cun fu(愁陽春賦)〉, 〈Bei qing qiu fu(悲清秋賦)〉, 〈Jian ge fu(劍閣賦)〉, 〈Ming tang fu(明堂賦)〉, 〈Da lie fu(大獵賦)〉. Those works are divided into Changpian Dafu(长篇大赋) and Shuqing Xiaofu(抒情小赋) two parts in form, and included irony, nostalgia and other aspects in content. This article starts the research of those works of fu through effects of the former dynasties’ works of fu, motivations of creation and features of illustration three parts, and got conclusions as below. Firstly, there is a trace of imitating other writes fu in Li Bai’s work since he got effected from their works, but Li Bai also has his own unique opinions on fu. In another words, Li Bai’s fu not only inherited the tradition of fu, but also presented some innovations. Secondly, Li Bai created fu sometimes for showing his aspirations, sometimes for pursuing fame and fortune, and sometimes for expressing his emotions. Thirdly, In Li Bai’s fu, he used different illustrating skills, including exaggeration, mixture of emotions and scenes, quoting lots of allusion and so on. Even though all of those are the resulting of initial researches, it presented that Li Bai has his own unique artistic style. There are important meanings of knowing the content mentioned above for understanding Li Bai’s whole life and studying his literati thoughts and work’s features. The author hopes this article could play a role of appealing other creative and important ideas, expecting there are more and more people focus on Li Bai’s works of fu and conducting further research.

Based on these research results, it is recommended that in interface design, from the perspective of search efficiency, skeuomorphism style and flat style icons are equally important in adoption and design.

Effect of Heat-induced Formation of Rice Bran Protein Fibrils on Morphological Structure and Physicochemical Properties in Solutions and Gels

Ye-Hui Zhang,Li-Hua Huang 한국식품과학회 2014 Food Science and Biotechnology Vol.23 No.5

The effects of heat-induced rice bran protein(RBP) fibrils on structure and properties of solutions and gelsin a complex system were investigated using transmissionelectron microscopy (TEM), atomic force microscopy(AFM), Congo red spectral analysis, and circular dichroism(CD). Planar and 3-dimensional images of RBP fibrils allrevealed structural details. A Congo red spectral shiftindicated fibril formation. Fibril secondary structuralcomponents exhibited differences at pH 2.0 and pH 7.0. The β-type was decreased with an increased pH. Rheological results exhibited shear thinning behavior forall solutions. Addition of fibrils to RBP solutions, whichmade the system complex, resulted in an order of magnitudeincrease in viscosity and shear stress. Adding fibrils toRBP solutions accelerated the kinetics of gel formation,resulting in an increase in gel strength. Scanning electronmicroscopy (SEM) images showed gel network structuraldifferences with and without fibrils at different pH values.

YE Bin,TAO De-hua 한국트라이볼로지학회 2002 한국트라이볼로지학회 학술대회 Vol.2002 No.10

The tribolugical characteristic of several environmentally friendly lubricating base stocks was examined, and the effect of some commonly used additives on the tribological behavior of the lubricating oils was comparatively investigated on a four-ball machine. It has been found that the commercial additives including butene sulfide, wax chloride, zinc dialkyldithiophosphate and ashless P-N type agent helped to improve the friction-reducing and antiwear properties as well as the extreme pressure behavior. Non-toxic nanoscale (CF)x showed the best friction-reducing ability, though it registered relatively poor extreme pressure properties. The mechanism on friction of nano-scale material is discussed.
