基于隐喻映射的产品感性关联认知分析与应用

目的运用隐喻映射方法,以喻体的分析为基础,围绕产品创意设计中的关系数据库建立隐喻与产品之间系统化、条理化的感性关联认知关系。方法首先通过产品隐喻中的喻体来构建产品本体与隐喻之间的关联,提出隐喻理解和认知构建过程,然后在分析用户需求的基础上进行隐喻映射模型的层次建立,细化和完善感性特征要素,实现产品新对象新特性的识别。结果从中式餐具产品的隐喻映射模型分析得到本体与喻体相互间新建立的认知关系并着重分析其差异,对照原有隐喻映射关系从而识别出新产品设计中的创新点。结论隐喻映射分析的方法便于可视化认知设计的构建,具有对产品进行感性形象化描述的优势。

蒙汉民族ASAP1、NRAMP1、SP110基因表达水平与结核病易感性关联分析

结核病(TB)发病具有种族易感性的分布特点,揭示结核病种族易感性的发病机制对明确结核病的高危人群、制定相应的防控策略具有重要作用。本研究从宿主易感相关基因转录水平出发,探讨ASAP1、NRAMP1和SP110表达水平与蒙古族和汉族结核病发病的关联程度。基于病例-对照研究设计,收集蒙古族和汉族96例结核病患者和126例健康人群静脉血,采用实时荧光定量PCR的方法检测易感性关联基因ASAP1、NRAMP1和SP110的mRNA表达水平,并分析不同民族间、结核患者与健康对照组间基因表达水平的差异。蒙古族结核患者结核易感基因ASAP1、NRAMP1 mRNA表达水平明显高于对照组(P<0.05),汉族结核病患者NRAMP1表达水平高于对照组(P<0.05)。蒙古族女性结核病患者,SP110的表达显著性差异(P<0.05)。汉族ASAP1、SP110 mRNA表达在结核病患者与对照之间没有显著差异。蒙汉民族结核病发病易感性与宿主基因ASAP1、NRAMP1和SP110表达有关,尤其是女性人群。提示结核病防治过程中可参考这些易感基因的表达评估结核病高危人群。

维特根斯坦的“家族相似”对理性主义与非理性主义的双重反叛

西方传统哲学的理性主义和非理性主义并非两个对立面,非理性主义其实是以理性思维为基础的,因此西方传统哲学的“共相”概念包含了理性和非理性双重向度。维特根斯坦以“家族相似”概念对西方传统哲学的“理性共相”的批判和对“感性共相”的回归,既澄清了感性关联与共相之间的张力,也对西方传统哲学的核心概念“共相”所蕴含的理性主义和非理性主义双重向度进行了批判,最终导致了他与西方传统哲学中的理性主义和非理性主义的彻底决裂。

Association between Two Polymorphisms of Follicle Stimulating Hormone Receptor Gene and Susceptibility to Polycystic Ovary Syndrome: a Meta-analysis

Objective To investigate the association between two polymorphisms of follicle stimulating hormone receptor （FSHR） gene and polycystic ovary syndrome （PCOS） susceptibility. Methods Case-control studies on relationship of Thr307Ala and Asn680Ser polymorphisms in FSHR gene and PCOS susceptibility were searched from PubMed, ISI web of knowledge, EBSCO, and China National Knowledge Infrastructure （CNKI） databases up to March 21, 2013. The pooled odds ratio （OR） and 95% confidence interval （CO were calculated using fixed- or random-effect model based on heterogeneity test in 5 genotype models analyses. Results A total of 11 studies were included in the Meta-analysis. The random-effect analysis showed Asn680Ser was significantly associated with the reduced susceptibility to PCOS with dominant model （Asn/Asn＋Asn/Ser vs. Ser/Ser, OR=0.83, 95% CI： 0.69-1.00）, recessive model （Asn/Asn vs. Asn/Ser＋ Ser/Ser, OR=0.84, 95% CI： 0.72-0.98）, homozygote comparison （Ash/Ash vs. Ser/Ser, 0R=0.79, 95% CI： 0.63-0.98）, and the allele contrast （Asn vs. Ser, OR=0.87, 95% CI： 0.79-0.97） respectively（P=0.02, I2=56.0%）, being protective factors for PCOS. However, no significant associations were found between Thr307Ala and PCOS. Conclusion There might be a significant association between Asn680Ser polymorphism and PCOS.

No association between IRF3 polymorphism and susceptibility to hepatitis B virus infection in Chinese patients

AIM:To investigate the association between three tag single nucleotide polymorphisms (tagSNPs) in inter-feron regulatory factors (IRF3) and the genetic suscep-tibility to chronic hepatitis B virus (HBV) infection.METHODS:We performed a case-control study of 985 Chinese cases of chronic HBV infection and 294 self-limiting HBV-infected individuals as controls.Three tagSNPs in IRF3 (rs10415576,rs2304204,rs2304206) were genotyped with the Multiplex SNaPshot technique.The genotype and allele frequencies were calculatedand analyzed.RESULTS:The three SNPs showed no significant geno-type/allele associations with chronic HBV infection.Overall allele P values were:rs10415576,P=0.0908,odds ratio (OR) [95% confidence interval (CI)]=1.1798 (0.9740-1.4291);rs2304204,P=0.5959,OR (95% CI)=1.0597 (0.8552-1.3133);rs2304206,P=0.8372,OR (95% CI)=1.0250 (0.8097-1.2976).Overall genotype P values were:rs10415576,P=0.2106;rs2304204,P=0.8458;rs2304206,P=0.8315.There were no statisti-cally significant differences between patients with chron-ic HBV infection and controls.Haplotypes generated by these three SNPs were also not significantly different between the two groups.CONCLUSION:The three tagSNPs of IRF3 are not asso-ciated with HBV infection in the Han Chinese population.

Association between gene polymorphisms of vitamin D receptor and pulmonary tuberculosis susceptibility:a meta-analysis

The vitamin D receptor （VDR） gene is a primary candidate gene for tuberculosis susceptibility, but results of previous studies are somewhat contradictory and underpowered. Thus, it is essential to further explore the association between VDR gene polymorphisms and risk of pulmonary tuberculosis （PTB）. Methods： A systematic review and meta-analysis about the association between Fok[, TaqI, Apal and Bsm[ polymorphisms and PTB susceptibility was conducted. Statistical Package for Social Science （Version 13.0） and Review Manager （Version 4.2, The Cochrane Collaboration） were used to analyze the data reported in studies. Results： A total of 13 studies with 2 262 cases and 2 833 controls were involved in the FokI polymorphism, and the results showed FokI polymorphism was associated with PTB susceptibility （allele f vs F： OR=1.12, 95% CI=[1.02, 1.23]; the additive effect model ff vs FF： OR=1.40, 95%CI=[1.10, 1.77]; the recessive genetic model firs Ff＋FF： OR=1.39, 95%CI=[1.12, 1.71]）. No significant associations were observed between TaqI （15 studies with 3 031 cases and 3 132 controls）, ApaI （7 studies with 1 495 cases and 1 922 controls）, BsmI （6 studies with 919 cases and 1 250 controls） variants and PTB susceptibility. Conclusion： We found variant Fokl polymorphism of VDR gene may play a risky role in PTB development, and the genetic model was presumed to be recessive.

Alternating current sensor system using GMM

Based on the principle of FBG sensing mechanism,an alternating current sensor system,which uses a FBG attached on a magnetostrictive rod as the probe,was developed.A dynamic interrogation method was proposed based on wide band light source,by making use of the linear relationship between its power intensity and wavelength as spectrum filter.A 50 Hz AC signal is interrogated successfully through the developed system and the system transfer function was established.The amplitude and frequency of the AC signal to be measured can be well deduced through the transfer function of the system, so the alternating current measurement is accomplished.
