《登记公约》实施中的若干法律问题研究

1976年《登记公约》确定了发射国对其发射的空闯物体的登记义务,从而建立了空间物体的强制登记制度.随着空间科学的进步和空间活动商业化的发展,《登记公约》在实施过程中逐渐暴露出缔约国数量偏少、未登记空间物体数量较多、登记信息不统一等缺陷,严重影响了其实施的效果.因此,应当在适当的时机对公约加以修订,完善公约的内容,以使其适应空间活动的现状.     

The Application of Flow Cytometry as a Rapid and Sensitive Screening Method to Detect Contamination of Vitreous Humor Samples and Avoid Miscalculation of the Postmortem Interval

Research into maximizing the speed, precision, and reliability of estimating the postmortem interval (PMI) has been a recurring object of investigation and methodologies based on the vitreous humor (VH) have provided good results. However, contamination from causes not readily apparent, such as blood, can occur, and thus lead not only to an erroneous estimation of PMI, but also interfere with the correct identification of other substances in the VH. We have developed a flow cytometry method which quantifies blood contamination and is able to detect erythrocytes in 1:750,000 dilution of contaminated VH which affects the results of hypoxanthine. It is an improvement on the previous more complex mass spectrometry method, being faster, more sensitive, and readily available. As such, it could be proposed for the rapid screening of appropriate samples by detecting and eliminating blood contaminated samples from PMI estimation.     

流动人口来京主要成因分析

流动人口来京的主要成因包括城市化因素、经济因素、区位因素、文化教育因素和交通设施因素五大方面。从城市化因素来看,北京的城市化进程是流动人口涌入北京的主要拉力,同时又影响着在京流动人口的区域分布;从经济因素来看,北京市经济增长与流动人口规模呈正相关关系,北京市产业结构决定了流动人口数量和结构及其分布;从区位因素来看,首都因素对人口流入的拉力效应明显,来京流动人口主要来自京津冀及环渤海区域,而且北京在全国特大城市中的竞争力也是其吸引人口流入的关键因素;从北京市的文化教育和城市基础设施因素来看,优质教育资源、历史文化名城的吸引力和包容性、全国交通枢纽地位和发达的城市基础设施是流动人口来京的重要推动因素。     

信息时代医院档案管理

随着电子计算机的普及深化，为了适应卫生体制的改革，医院也逐渐步入电子计算机管理和应用时代，医院的各项业务管理活动由传统的工作手段逐渐地由现代管理手段取代。如果一个医院不能主动适应社会变化。改进档案管理的方武。将有可能制约自身的发展。     

Chemical, physical and mineralogical characterization of soils from the Curitiba Metropolitan Region for forensic purpose

The objective of this paper is to propose a soil characterization methodology for forensic use, based on physical (textural and spectroscopic analyses), chemical (extractions with hydrofluoric acid, ammonium oxalate, sodium dithionite-citrate-bicarbonate and NaOH solution) and mineralogical (thermal analyses and X-ray diffraction) analyses. The study was carried out in the State of Paraná, Brazil, in three neighborhoods of Curitiba city and in two cities within the Curitiba Metropolitan Region. In order to verify the similarity between samples, four composite samples (repetitions) were prepared in each of the five studied sites. It was obtained a great number of quantitative variables (56) from a reduced amount of soil sample (1g). The variables selected from the chemical extractions (16) were more precise in grouping similar samples (same horizon and sampling site) as well as in separating samples collected in different horizons or sites. Seven distinct groups were formed, each with high intragroup similarity, but the unexpected dispersion of two samples (from a total of 40 samples) reduced the distinction of three other studied groups. The placement of the two samples in a different group and the higher dispersion (24 samples) for samples collected in the city of Curitiba are due to the great pedological homogeneity of this area (physical-chemical horizon characteristics, soil color and parent material). The methodology used in this work (analytical method and data treatment) presents high potential for forensic studies and can be easily validated for other areas.     

Shells and Bones: A Forensic Medicine Study of the Association of Terrestrial Snail Allopeas micra with Buried Human Remains in Brazil

Little is known regarding the scavenger fauna associated with buried human corpses, particularly in clandestine burials. We report the presence of 20 shells of the terrestrial snail Allopeas micra, within hollow bones of human remains buried for 5 years, during the process of collecting DNA material. The fact that a large number of shells of A. micra had been found in the corpse and in the crime scene supports the assumption that there was no attempt to remove the corpse from the area where the crime occurred. Despite this, our observations cannot be used to estimate the postmortem interval because there is no precise knowledge about the development of this species. This is the first record of a terrestrial snail associated with a human corpse and its role in this forensic medicine case.     

Cardiac Inhibitory Reflex as a Cause/Mechanism of Death

The role of cardiac inhibitory reflex as a potential cause of death is still a matter of debate. This study reports two cases of death under unusual circumstances. Case 1 corresponds to a man found hanging where the role of ligature compression of the carotid sinus became relevant as a possible explanation of death. In Case 2, the participation of a vasovagal syncope was clearly triggered by the laryngoscopic procedure. It is proposed that cardiac inhibitory reflex should be taken into account in those cases of unexpected death, which fulfills the following three criteria: (i) The investigation of the circumstances of the death is consistent with a hypothesis of cardiac arrest. (ii) A typical triggering peripheral stimulus is present. (iii) The performance of a complete autopsy cannot rule out the participation of a cardiac inhibitory reflex in the cause of death.     

过敏性休克死亡者肺组织类胰蛋白酶及类糜蛋白酶的表达

目的观察类胰蛋白酶与类糜蛋白酶在过敏性休克死亡人体肺组织中的表达,并探讨其在过敏性休克死亡法医学鉴定中的意义。方法应用荧光免疫组化法对类胰蛋白酶与类糜蛋白酶进行检测,同时以10例CO中毒死者为对照：采用图像分析仪及Image—pro plus 5．0．2软件进行图像分析,计算阳性肥大细胞数及类胰蛋白酶、类糜蛋白酶荧光表达强度。结果与对照组相比,实验组肺组织中类胰蛋白酶和类糜蛋白酶表达差异有统计学意义（P〈0．05）。结论过敏性休克死亡人体肺组织中类胰蛋白酶与类糜蛋白酶的表达增强．可作为过敏性休克死亡的形态学诊断依据。     

反劫持"以暴制暴"传统处置模式否定论

反劫持“以暴制暴”传统处置模式是与法治社会、生命至上理念和现代文明相悖的。反劫持行动应以外交式、绅士式、慈善式、和缓式的模式来进行,以求得稳中有重、控中有效、放中有收、刚中有柔的终极效果。否定“以暴制暴”传统处置模式的实质是用人性化的谈判方式解除劫持危机,并通过法律程序追惩犯罪。
