Data were collected from all related agencies. The results of this research have showed that executive process of forensic science is used to investigate the crime in three southern border provinces that can be divided the operations into three main issues as following： crime scene examination, evidence testing, autopsy in case of crime scene, and factors which affect forensic work for using in criminal investigation in three southern border provinces of police practitioners. They should have the knowledge about forensic science, commitment, bravery, and cunning work.展开更多

The ingredients used in the paste are turmeric rhizome, garlic, shallot and chili. However, for making the sour soup, the souring agent such as lime juice, tamarind pod or garcinia, fruit is added. This study aimed to compare quality changes, total phenolic compound and antioxidant properties of the pastes as affected of added garicia fruit during storage. It was found that the total phenolic compound content of basic paste without the garcinia, garcinia Keang-hleung paste and garcinia Keang-hleung paste without salt decreased as increased storage time. Moreover, the DPPH (2,2-diphenyl-1-picrylhydrazyl) radical scavenging activity and the ferric reducing power (FRAP) activity of the basic paste without the garcinia decreased as increased storage time. However, the DPPH radical scavenging activity and the FRAP activity of the garcinia Keang-hleung paste with and without salt increased during 2 months of storage period and then decreased as increased storage time. Total viable count (TVC) of all paste samples were in the range of 102 - 103 cfu/g. Yeast and mold counts of basic and garcinia Keang-hlueng paste were less than 30 cfu/g during storage. While, yeast and mold counts of garcinia Keang-hlueng paste without salt were less than 102 cfu/g during storage. Lactic acid bacteria counts of garcinia Keang-hlueng paste were less than 30 cfu/g during storage. While, lactic acid bacteria counts of the basic and garcinia Keang-hlueng paste without salt were less than 102 cfu/g during storage. However, Staphylococcus aureus, Bacilluus cereus, Clostridium perfringens, Salmonella spp., Escherichia coli and coliforms were not detected in all treatments throughout the storage period.展开更多
