In this study, the criteria of scientific content analysis were examined, and the statements of the people involved in 21 death cases were substituted into the criteria of scientific content analysis to analyze the statements of the people involved.

The density and width of strokes were measured by applying a constant pressure (100-300 g) to a total of 39 ballpoint pens of 4 types of ink (oil, low-viscosity oil, gel and water) and ball size (0.5-1.0 mm). As a morphological characteristic of stroke density, it was confirmed that there were four types: 1) Selective diffusion of high-viscosity ink, 2) Agglomeration, 3) Dot, 4) Selective diffusion of low-viscosity ink. The deposition value of ink stroke density showed a tendency to be measured twice as low for oil (33.74~47.26%) with high viscosity compared to gel (78.19~84.66%) and water (44.96~85.26%) with low viscosity of ink. The stroke width showed a tendency to increase as the pressure applied to the ballpoint pen and the size of the ball increased. The stroke width according to the ink was similar in the case of oily and low-viscosity oils, but in the case of neutral, it was about 100 μm higher than that of oil and low-viscosity oils. As a result, the density and width of strokes showed a difference in the characteristics that appeared according to the viscosity of the ink. In the order of non-destructive analysis for the identification of writing instruments, it is necessary to ① analyze the deposit shape and deposit value of ink stroke density, and ② to estimate the ink and ball size through ink width measurement. It was confirmed that it can be used.","PeriodicalId":189866,"journal":{"name":"The Korean Academy of Scientific Criminal Investigation","volume":"78 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2022-09-30","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"126974631","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

We aimed to compare the performance of 16S rRNA gene sequencing, and two commercially available API 20E and RT-PCR systems to distinguish between E. coli and Shigella spp. on the basis of analysis of 24 isolates collected from 12 forensic autopsies to evaluate the level of species identification. The accuracy of 16S rRNA gene sequencing at the species level was ranged from 16.7% to 33.3%. However, 79.2% (19/24) were unidentified, even though analyzed using three distinct databases (MicroSEQ 500 library, BLAST, EzTaxon). Phylogenetic analysis confirmed that 16S rRNA gene sequencing could not differentiate Shigella spp. and E. coli. Of the 19 isolates, the API 20E showed complete identification of 78.9% (15/19) at the species level, whereas RT-PCR analysis showed complete identification of 19 isolates (100%) at the species level. Our comparison analyses revealed that only 16S rRNA gene sequencing is not enough to differentiate E. coli and Shigella spp., and the accuracy and rapidity order was as follows: RT-PCR >API 20E>standard analysis. These results suggest that the polyphasic strategy with the standard analysis and RT-PCR or API 20E techniques are ideal for differentiation of these microbes.","PeriodicalId":189866,"journal":{"name":"The Korean Academy of Scientific Criminal Investigation","volume":"42 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2022-09-30","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"134644934","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

The act of puncture is an invasive examination method that may cause damage to the body of the deceased, but the extent of damage is not large and the data about analysis of puncture can be useful to determine the exact cause of death or whether to proceed to the autopsy stage. However, as one of the methods of postmortem investigation, the act of puncture has the same characteristics as investigative verification, so if it is a forced investigation, a warrant must be issued before and after the act of puncture. If a certain medical professional performs the puncture, and if the detailed procedures and methods are determined and implemented in advance, it will contribute to the rapid and accurate determination of the cause of death in a legal basis. A postmortem examiner with medical expertise will be responsible for sample collection by puncture, and the postmortem examiner may directly conduct sample analysis at a certain analysis facility or request a separate forensic science analysis agency. On the other hand, although sampling and analysis by puncture will be very helpful in identifying the cause of death, it should be recognized that it is a complementary method of external autopsy of the corpse and is only used as useful judgment data related to autopsy, and is not a substitute for autopsy.","PeriodicalId":189866,"journal":{"name":"The Korean Academy of Scientific Criminal Investigation","volume":"32 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2022-06-30","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"126543137","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

The most common method of collecting fibers at crime scenes is tape lifting, and for various analyses, fibers must be separated from the tapes. Various methods of separating fibers are being used, but most of them require a lot of time and effort. Thus simpler and faster collecting method is required. By transferring the solvent to a fiber attached site by using the capillary action of tweezers to the area to which the fiber is attached, it is possible to immediately collect the fiber with tweezers after dissolving the adhesive component. In addition, it can significantly reduce the harmfulness caused by solvent inhalation due to a trace amount of solvent transfer by capillary action. This solvent transfer method by capillary action can be applied to the V-shaped cutting method for individual fiber preparation and the fiber attached surface collection one for a large number of fibers to enable fast collection of fibers.","PeriodicalId":189866,"journal":{"name":"The Korean Academy of Scientific Criminal Investigation","volume":"6 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2022-06-30","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"130134934","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
