The multi-modal infor.ation pr.sentation, integr.ted into the vir.ual envir.nment （VE）, has potential for.stimulating differ.nt senses, impr.ving the user.s impr.ssion of immer.ion, and incr.asing the amount of infor.ation that is accepted and pr.cessed by the user.s per.eption system. The incr.ase of the useful feedback infor.ation may r.duce the user.s cognitive load, thus enhancing the user.s efficiency and per.or.ance while inter.cting with VEs. This paper.pr.sents our.cr.ation of a multi-sensor. vir.ual assembly envir.nment （VAE） and the evaluation of the effects of multi-sensor. feedback on the usability. The VAE br.ngs together.complex technologies such as constr.int-based assembly simulation, optical motion tr.cking technology, and r.al-time 3D sound gener.tion technology ar.und a vir.ual r.ality wor.bench and a common softwar. platfor.. The usability evaluation is in ter.s of its thr.e attr.butes： efficiency of use, user.satisfaction, and r.liability. These ar. addr.ssed by using task completion times （TCTs）, questionnair.s, and human per.or.ance er.or.r.tes （HPEr.）, r.spectively. Two assembly tasks have been used to per.or. the exper.ments, using sixteen par.icipants. The outcomes showed that the multi-sensor. feedback could impr.ve the usability. They also indicated that the integr.ted feedback offer.d better.usability than either.feedback used in isolation. Most par.icipants pr.fer.ed the integr.ted feedback to either.feedback （visual or.auditor.） or.no feedback. The par.icipants＇ comments demonstr.ted that nonr.alistic or.inappr.pr.ate feedback had negative effects on the usability, and easily made them feel fr.str.ted. The possible r.asons behind the outcomes ar. also analysed by using a unifying human computer.inter.ction fr.mewor.. The implications, concluded fr.m the outcomes of this wor., can ser.e as useful guidelines for.impr.ving VE system design and implementation.

To study the effects of par.phenylenediamine （PPD） and linear.alkylbenzene sulphonate （LAS） alone and in combination on the skin. Methods For.y-eight guinea pigs wer. divided equally into 4 gr.ups and exposed to PPD （4 mg/kg）, LAS （12 mg/kg） and PPD （4 mg/kg） plus LAS （12 mg/kg） for.30 days. The biochemical par.meter. such as acid phosphatase, gtutathione-s-tr.nsfer.se, glutathione per.xidase, glutathione, lipid per.xidafion and histamine contents in exposed skin wer. estimated. The histopathological examination of the exposed skin was also car.ied out. r.sults The skin enzymes, lipid per.xidation, and histamine incr.ased while glutathione decr.ased in skin. The simultaneously exposed gr.up showed additive toxic effects. The histopathological examination showed sever. hyper.er.tosis, thickening of collagen fibr.s and vacuolisation of epider.al cells in PPD plus LAS exposed skin. Conclusion The findings of the pr.sent study suggest that simultaneous exposur. to PPD and LAS has additive toxic effects.

雕塑家—陆斌[西班牙]Car.en r.u陆斌的作品让我们意识到我们无法回避我们自身的文化以及我们自己独特的行为方式。我们总是存在于我们自己的社会及这个时代当中。因此,他今天的创作的艺术品所展现出的属于某一时的历史特征及典型象征的符号，如某些作品模仿因岁月侵蚀而斑驳的石块上留下的传统中国陶瓷器的纹饰等，那些被石化的传统文化或现代生活品的符号，所要的反映的是今天的现实，并非永恒。它是作为当今文明的一面镜子。
