Application of 3D Laser Scanner to Forensic Engineering

In the case of building collapses and overturned structures, a three‐dimensional (3D) collapse or overturn model is required to reconstruct the accident. As construction sites become increasingly complex and large, 3D laser scanning is sometimes the best tool to accurately document and store the site conditions. This case report presents one case of a structure collapse and one case of an overturned crane reconstructed by a 3D laser scanner. In the case of structural collapse of a prefabricated shoring system, a 3D model reconstructed all the members successfully, a task that is nearly impossible using a scale such as a tape measure. The reconstructed prefabricated shoring system was verified through a structural analysis through comparison with the construction drawings to investigate faults in construction. In the case of the overturned crane, the jib angle and other major dimensions were successfully acquired through 3D laser scanning and used to estimate the working radius. As a result, the propriety of the working radius with the given lifting load was successfully determined.     

Latent Fingermark Development on Thermal Paper using 1,2‐Indanedione/Zinc and Polyvinylpyrrolidone,

Polyvinylpyrrolidone (PVP) has been used in combination with 1,2‐indanedione (1,2‐IND) and ZnCl₂ (Zn) to develop latent fingermarks. The results show that the optimal ratio of 1,2‐IND/Zn:PVP is 1.0:0.4 (the concentration of PVP is 8%) for developing fingermark. The developed formulation was tested on the surfaces of 12 kinds of thermal papers. The variation in the fingermark development efficiency was observed within the same and among different kinds of thermal papers. The fingermark development efficiency was mostly better on the thermally sensitive surface compared to the thermally nonsensitive surface. However, similar or even better development was observed from a few thermally nonsensitive surfaces. The present method has shown better efficiency compared to the three other proposed methods on the thermally sensitive surface. In contrast, the present method was proven not the best for the thermally nonsensitive surface.     

Collection of Wet‐Origin Footwear Impressions on Various Surfaces Using an Electrostatic Dust Print Lifter

Electrostatic dust print lift method is known to be able to recover only dry‐origin footwear impression. However, the wet‐origin footwear impression could also be recovered using this method. As the amount of dust accumulated before deposition of the wet‐origin footwear impression increased, the intensity of the footwear impression lifted with this method became stronger. If the footwear impression is not affected by moisture after it is made, the 28‐h old wet‐origin footwear impression could be recovered using this method. The intensity of the lifted footwear impression did not decrease significantly even when the number of sequential steps increased as long as the shoe sole is wet. However, when the moisture on the shoe sole depleted, the intensity of the footwear impression decreased sharply. This method has the advantage of being able to enhance the footwear impression without being affected by the footwear impressions deposited in the past.     

养老保险支付危机解决途径的思考

本已承担隐性债务重压的养老保险基金,在市场经济新趋式下,面临着企业改制带来的大量失业下岗工人、企业私有化进程加快后的养老保险金拖、欠、瞒、缴的现象及退休潮到来引发的养老金大量支付等新情况,如何应付养老保险的支付危机,应在基金来源、基金资本运作、基金支出三方面采取可行措施、开源节流,以确保养老保险基金的收支平衡。

我国政府再造面临的三大问题

20世纪80年代以来,西方掀起"政府再造"(政府改革)的浪潮,但这种"政府再造"思路,在多大程度上适合于我国政府改革,是很值得认真思考的.文章更多的从制度经济学的角度对"政府再造"理论中国化、"政府再造"理论的适用范围和"政府再造"的实践这三方面进行分析,以浅述我国政府再造所面临的问题.     

现代法治进程中的中国传统法律文化

推进政治体制改革,建设社会主义法治国家,必须从中国的国情出发,不照搬政治制度的模式,这是邓小平理论中法制思想的重要内容。这里所讲的中国国情,当然包括中国的法律文化传统在内。对中国法律文化传统不能一味否定,其中也有许多在今天仍值得弘扬的东西。中国在建设法治社会的过程中亦应如此,我们应当学习借鉴西方法律文化传统中的优秀部分,吸取中国法律文化传统中所独有的东西,把中西两种法律文化融汇起来,建立起具有中国特色的法治社会。

新常态下的劳动关系与工会工作

经济新常态以速度变化、结构优化、动力转化为主要特征,劳动关系相应呈现集体劳动争议复杂化、高频率的特点。工会面临失去新生代劳动者信任的挑战。工会应加强自身建设,维护劳动者合法权益,积极参与相关立法和争议处理活动。
