Status Quo and Expectation of Human-machine Interaction in HCR

Human-centered idea and human-machine collaboration are emphasized in the Human Centered Robotics, which is mainly used for human-machine cooperation required mission in dynamic and non-structural environment. This paper presents a WearComp based interface that gets over the space and time limitation on human-robot interaction. By adapting AR(augment reality) in outputting channel, the information of robotics status and warning was accentuated in the transmission. That method effectively saves the resources of transmission band and reappearance, lightens the burden of operators and contributes to a good operator consciousness to local condition and remote environment. By parallel and mutual compensation of MultiModality interaction, and by integrating and fusing the redundant information, the ambiguity and noise of inputting information can be eliminated. All of above get rid of input bottleneck; a more efficient and humanistic human machine interaction is provided.     

新农村建设中的人力资源问题

目前,我国农村的人力资源无论在数量上还是在质量上都难以满足新农村建设的要求。政府应制定切实可行的政策保证农村人力资源的数量和质量;应通过基础教育、职业教育和成人教育,完善医疗和社会保障制度等途径提高农村人力资源的质量。开发农村人力资源应借鉴国外成功经验。     

人乳低聚糖研究进展

随着人们对人乳低聚糖（human milk oligosaccharides,HMOs）分布、有益生物活性,特别是调节人体肠道菌群益生元活性的认识日益深入,HMOs的相关研究越来越受到重视。然而,HMOs的应用通常是困难的,挑战在于适用于婴幼儿配方乳粉HMOs的特殊选择和天然来源中有限的HMOs含量,特殊HMOs应用的困难在于对于特定HMOs含量及其对儿童健康影响的研究很少。本文综述母乳中复杂的HMOs成分、可能的产品来源、功能和安全问题等方面的研究现状,重点综述HMOs成分、HMOs来源、HMOs生物活性的最新研究进展及未来研究方向。     

寿昌江河流泥沙来源研究

人类活动是影响河流泥沙淤积的重要因素,为探讨道路建设和河道破坏对河流产沙的影响,以浙江省寿昌江流域为研究对象,采用复合指纹识别示踪技术,得到了不同潜在泥沙来源区对河流产沙的贡献。结果表明:采用Kruskal-Wallis H-test(KW-H)与多元判别分析(DFA)组合、主成分分析(PCA)与DFA组合得到的指纹示踪因子,结合复合指纹示踪模型,均能够很好地区分泥沙来源,但PCA和DFA统计法得到的4个指纹示踪因子组合能更好地区分泥沙来源。在河流出口处,来自河道的泥沙最多,占河流总产沙的34.7%,其次是建设用地,其产沙贡献为总产沙的28.1%,来自林地和水田的泥沙贡献分别为24.1%,12.7%,旱地产沙贡献最小,仅为0.3%。降水、土地利用、造桥、挖沙及道路建设等是引起产沙贡献差异的重要原因。因此,寿昌江流域降雨量大,植被覆盖度高,河流泥沙主要来自人类生产建设对地表的破坏。     

滇西南植被覆盖度动态变化特征及其驱动力分析

为了探究滇西南植覆盖度动态变化及与气候因子的关系,以便于推动滇西南植被资源保护以及可持续发展。基于滇西南2000—2020年MODIS NDVI数据以及同期气象数据,运用像元二分法、转移矩阵、线性趋势分析、相关分析和残差分析等方法进行了分析。结果表明:(1)滇西南近21 a低植被覆盖度逐渐向高植被覆盖度转化,2000—2020年滇西南植被覆盖度整体呈现改善趋势。(2)滇西南近21 a年累计降水量以94.18 mm/10 a的趋势减少; 年均气温以0.78℃/10 a的趋势上升。(3)滇西南植被覆盖度主要与气温变化关系更密切,其中FVC与气温正、负相关面积占整个研究区比例分别为58.47%,41.53%; 与降水量正、负相关面积占整个研究区域比例分别为41.22%,58.78%。(4)气温驱动为滇西南植被覆盖度的主要驱动因素,占研究区域面积的2.94%; 降水量驱动区域所占1.76%; 受气温和降水量共同驱动区域所占2.66%。(5)近21 a滇西南残差值以0.021/10 a的速率波动上升。2000—2020年滇西南人类活动对植被的影响由负到正,其中2009年为由负到正的转折点。     

Effect of Scutellaria barbata flavonoids on abnormal changes of Bcl-2, Bax,Bcl-xL and Bak protein expression in mitochondrial membrane induced by composite Aβ25-35

AIM：To study the abnormalities of Bcl-2, Bax, Bcl-xL and Bax in the cell mitochondrial membrane of cerebral cortex in the rats injected with β-amyloid beta protein 25-35 (Aβ25-35) in combination with aluminum trichloride (AlCl3) and recombinant human transforming growth factor β1 (rhTGF-β1) (composite Aβ25-35) into lateral cerebral ventricle, and to explore the intervention of Scutellaria Barbata flavonoids (SBF). METHODS：The male SD rats were used to establish the neuronal damaged model by receiving injection of RhTGF-β1 1 μL (10 ng) on day 1 of operation, and then from day 2 of operation, intracerebroventricular injection of Aβ25-35 (4 μg/d, consecutive 14 d) in the morning and 1% AlCl3 in the afternoon (3 μL/d, consecutive 5 d). On the day 49 of operation, the successful model rats were randomly divided into model control and 3 doses of SBF groupss. The rats in SBF groups were daily orally administered with SBF at doses of 35, 70 and 140 mg/kg for 36 d. All the rats were decapitated 60 min after the last administration. The protein expression of Bcl-2, Bax, Bcl-xL and Bak in rat cerebral cortex cell mitochondrial membrane was detected by Western blotting. RESULTS：The composite Aβ25-35 dramatically caused decreases in Bcl-2 and Bcl-xL (P<0.05), and increases in Bax and Bak (P<0.01) in rat cerebral cortex cell mitochondrial membrane. However, oral treatment with SBF for 36 d reversed the above disorders induced by composite Aβ25-35. CONCLUSION：The composite Aβ25-35 induces the expression abnormalities of Bcl-2, Bax, Bcl-xL and Bak in mitochondrial membrane and SBF reverses the above disturbances of apoptotic factors.     

Expression and methylation regulation of CHFR in endometrial cancer cells

AIM: To study the expression and methylation status of checkpoint with forkhead-associated and ring finger ( CHFR ) in human endometrial cancer cell lines and to explore the effect of demethylation on the colony formation of the cancer cells.METHODS: The expression level of CHFR in endometrial cancer cells was evaluated by semi-quantitative RT-PCR and Western blotting.The methylation status of CHFR was detected by methylation-specific PCR.The proliferation of RL-952 cells was analyzed by colony formation test.RESULTS: Lower expression of CHFR was detected in endometrial cancer cells, especially in RL-952 cells, than that in normal fibroblast (NF).CHFR was weekly expressed in RL-952 cells, the gene of which had aberrant hypermethylation.The unmethylation band of CHFR was observed in NF cells and ISH cells, which had high expression of CHFR.After exposed to 5-azacytidine (5-aza), the methylation band in RL-952 cells disappeared with the recovery of both CHFR mRNA and protein expression, and the colony-forming efficiency was greatly inhibited.CONCLUSION: Aberrant promoter methylation is the main reason for decreasing CHFR expression in endometrial cancer cells.5-aza could restore CHFR expression and inhibit the colony formation effectively.     

中国古代法制建设中的情与法——以清代犯罪存留养亲为例

人性论是中国古代法制建设中情法交融的思想基础,清代存留养亲制度中的情法兼顾具有惩治犯罪、安抚民心的功能。中国古代的情法兼顾与现代社会的"司法一元化"没有可比性。
