Two cellular embeddings i ： G→S and j ： G → S of a connected graph G into a closed orientable surface S are equivalent if there is an orientation-preserving surface homeomorphism h ： S → S such that hi = j. The genus polynomial of a graph G is defined by g[G]（x）=∞∑g=0agx^g, where ag is the number of equivalence classes of embeddings of G into the orientable surface Sg with g genera. In this paper, we compute the genus polynomial of a graph obtained from a cycle by replacing each edge by two multiple edges.

Background Hypertension is a common chronic disease among older adults, and is associated with medical complications and mor- tality. This study aimed to examine the effects of social network characteristics on the prevalence, awareness, and control of hypertension among older adults. Methods The Korean Social Life, Health, and Aging Project （KSHAP） interviewed 814 〉 60-year-old residents and their spouses from a rural township between December 2011 and March 2012 （response rate： 95%）. We evaluated the data from 595 partici- pants. Multivariate logistic regression models were used to assess the effects of network characteristics on hypertension. Results We ob- served strong sex-specific network effects on the prevalence, awareness, and control of hypertension. Among older women, network density was associated with hypertension awareness [odds ratio （OR）： 2.63, 95% confidence interval （CI）： 1.03 5.37j and control （OR： 1.72; 95% CI 0.94-3.13）. Among older men, large networks were associated with a lower prevalence of hypertension （OR： 0.75; 95% CI： 0.58-0.96）. Compared to older women, older men with coarse networks exhibited better hypertension awareness （OR： 0.37; 95% CI： 0.14-0.95） and control （OR： 0.42; 95% CI： 0.19-0.91 ）. Network size interacted with density for hypertension control （P = 0.051）, with controlled hyperten- sion being associated with large and course networks. Conclusions A large network was associated with a lower risk for hypertension, and a coarse network was associated with hypertension awareness and control among older men. Older women with dense networks were most likely to exhibit hypertension awareness and control.

AIM: To investigate nasolacrimal duct(NLD) volume in Korean patients and to examine the correlation between NLD volume and obstruction. METHODS: Of patients who underwent orbital computed tomography from March 2013 to january 2016, patients diagnosed with NLD obstruction were classified into the patient group and patients without obstruction were classified into the control group. The NLD volume was measured using the Image j program, which showed the NLD in axial,coronal, and sagittal images on computed tomography. RESULTS: The average value of men's NLD volume,265.33±90.57 mm3, was significantly larger than women's,211.87±68.61 mm3(P=0.009). In the patient group, the NLD volume of the obstructed eyes, 242.49±82.93 mm3,and the non-obstructed eyes, 225.20±73.20 mm3, were significantly higher than the control group, 217.61±82.04 mm3(Pjudged that inflammatory reaction caused a chronic change in the bone around the NLD and affect the measurement of NLD volume.

社会和文化之间有密切的关系,社会在不断地发展和变化,与此同时文化也在不断发展和变化。为了与一个国家的成员更好地融合,更好地了解这个国家成员的价值、习惯,那么了解这个国家的文化至关重要。文化反映在社会各个角落,要了解社会,首先要了解语言。学语言时,要尊重和理解异国文化,如果秉持排斥文化的态度,理解语言是不可能的。社会、语言、文化有着如此密切的关系。现在中国正在不断发展。世界各地的学生纷纷来到中国。带着本人的母语和本人的文化,来学习新的语言和文化。这些人大部分是二三十岁的年轻人,想知道世界社会正在发生怎样的事情,世界在发生怎样的变化。文化课应适应这种变化,从现有的中国文化课程来看,关于中国传统文化的部分相当多,当代文化部分只有简单的介绍。正如前面所说,随着当代社会迅速变化,文化也在迅速变化。但是有关当代文化课程和当代文化的内容却寥寥无几。笔者在翻看前人关于中国文化课偏好度研究的相关论文时,也曾提到当代文化教育的重要性,但还存在一定的研究空间。所以,笔者以j国际学生对中国文化偏好度为研究对象,通过研究了解学生的真实情况。在本论文研究的过程中,我们不仅限于以掌握学生的喜好程度为研究视角,而是从多角度对文化课的整体情况进行研究分析。问卷由学生的教育现状、学习动机、教育满意度三部分组成。为进一步多角度地进行研究分析,在此基础之上,细分为文化课程、中国文化、语言文化三类。在学习动机上,也大致分为内在动机、确认调节动机、过度调节动机和外部调节动机这四种具有代表性的动机。此外,在问卷调查之外,还进行了深入采访,参考了学生比较有针对性的意见和建议,使本论文的研究成果更加客观、真实且具有可信度。事实上,当代社会也创造新的文化。但是,根据这种变化,教师编写新的教材,熟悉新文化,并制作成讲座并不是一件容易的事情。本论文调查分析中国文化课教育现状,得出如果将现有的传统文化和当代文化很好地融合起来,留学生们就能更快地对汉语感兴趣并适应在中国的生活。本论文的重点是分析当前吉林大学国际学生对文化课的偏好度。但通过了解学生的需求和想法,可以为本论文的研究提供支持。同时,根据笔者的研究提出行之有效的方法,为留学生更好的学习中国文化指明方向。

Despite the safety,low cost,and high theoretical capacity(820 mA h g^(-1))of Zn metal anodes,the practical application of aqueous Zn metal batteries remains a critical challenge due to the Zn dendrite growth,corrosion,and hydrogen evolution ***,we demonstrate the MXene ink hosting Zn metal anodes(MX@Zn)for high-performance and patternable Zn metal full *** as-designed MX@Zn electrode is more facile and reversible than bare Zn and CC@Zn,as verified by better cyclic stability and lower overpotentials of symmetric cells with the plating capacity of 0.05 mA h cm^(-2)at 0.1 m A cm^(-2)and of 1 m A h cm^(-2)at 1 m A cm^(-2).The MX@Zn|MnO_(2)full cells deliver a high specific capacity of 281.9 m A h g^(-1),91.5%of the theoretical capacity,achieving 50%capacity retention from 60 mA g^(-1)to 300 mA g^(-1)and 79.7%of initial capacity after 200 ***,the patterned devices based on the MX@Zn electrode achieve high energy and power densities of 348.57 Wh kg^(-1)and 1556 W kg^(-1),respectively,along with a capacity retention of 64%and Coulombic efficiency of 99%over 500 *** high performance of MX@Zn is attributed to the high electrical conductivity and hydrophilicity of MXene and rapid ion diffusion through the 3D interconnected porous channels.

Indole-3-acetic acid （IAA）, a major plant auxin, is produced in both tryptophan-dependent and tryptophan-independent pathways. A major pathway in Arabidopsis thaliana generates IAA in two reactions from tryptophan. Step one converts tryptophan to indole-3-pyruvic acid （IPA） by tryptophan aminotransferases followed by a rate-limiting step converting IPA to IAA catalyzed by YUCCA proteins. We identified eight putative StYUC （Solanum tuberosum YUCCA） genes whose deduced amino acid sequences share 50%-70% identity with those of Arabidopsis YUCCA proteins. All include canonical, conserved YUCCA sequences： FATGY motif, FMO signature sequence, and FAD-binding and NADP-binding sequences. In addition, five genes were found with -50% amino acid sequence identity to Arabidopsis trypto-phan aminotransferases. Transgenic potato （Solanum tuberosum cv. jowon） constitutively overexpressing Arabidopsis AtYUC6 displayed high-auxin phenotypes such as narrow downward-curled leaves, increased height, erect stature, and longevity. Transgenic potato plants overexpressing AtYUC6 showed enhanced drought tolerance based on reduced water loss. The phenotype was correlated with reduced levels of reactive oxygen species in leaves. The results suggest a func-tional YUCCA pathway of auxin biosynthesis in potato that may be exploited to alter plant responses to the environment.
