Forensic botany is a study of judicial plant evidence. Recently, researches on DNA labeling technology have been a mainstream of forensic botany. The article systematically reviews various types of DNA labeling techniques in forensic botany with enumerated practical cases, as well as the potential forensic application of each individual technique. The advantages of the DNA labeling technology over traditional morphological taxonomic methods are also summarized.

OBJECTIVETo establish fingerprint database of drug-resistant strain of Acinetobacter baumannii with AFLP genotype.

METHODSTwenty-seven strains of A. baumannii were clinically isolated. The microbial sensitivity to 13 antibiotics was analyzed according to NCCLS 2004. The genotype was analyzed by amplified fragment length polymorphism (AFLP) method.

RESULTSThe results were consistent with those with AFLP database.

CONCLUSIONThe database of AFLP fingerprint may have practical value for identification of drug-resistant Acinetobacter baumannii.

In historical cases, missing persons' identification, mass disasters, and ancient DNA investigations, bone samples are often the only and always the best biological materials available for DNA typing. There are many protocols for the extraction of DNA from bone samples. In our experiment, we tested three DNA extraction protocols: Ethanol down method, Microcon(R) YM-100 and DNA IQ(TM) system. We have found that ethanol down method is not suitable to extract DNA from bone samples and Microcon(R) YM-100 is the best among these three mothods. DNA IQ(TM) System did not show better result but needed less time and labor than Microcon(R) YM-100. So, we expect using DNA IQ(TM) System is useful in case of bone samples which are not severely contaminated .

The field of forensic DNA requires not only genetic typing but also social systems. The systems include the establishment of Korean guidelines for DNA typing. There were some publications relating DNA typing guidelines in 2001 and 2002, but the works could not be sustained. Although KOLAS and KIGTE are operating now, we can hardly say that these are optimal for forensic purposes. There also have been foreign publications about the DNA typing guidelines. Considering various differences among nationality, however, we need to establish suitable guidelines for Korean. Therefore, expert members in forensic society should be concern about Korean guidelines for DNA typing and participate in this work.

Serum is free of cellular components. Because DNA is located in the nuclei or mitochondria of cells, serum could be assumed DNA free. Few previously published case reports to date have used serum for DNA typing. Here, we report on human genotyping via short tandem repeat (STR) analysis using serum as a sample, and discuss problems involved in the process.

OBJECTIVE: To analyze and discuss four methods of calculating likelihood ratio of DNA mixture. METHODS: In the case with CNAS-T0757 proficiency testing in 2013, the likelihood ratios were calculated and compared among four methods, including unrestricted combinatorial method, Clayton's method, p2 principle method, and recommendations from ISFG. RESULTS: The likelihood ratios were maximum by Clayton's method and recommendations from ISFO, followed by result of the unrestricted combinational method. The minimum likelihood ratio was obtained by p2 principle. CONCLUSION The unrestricted combinational method could give fUrthest consideration to both information preservation and appraiser protection.
