Purpose: The purpose of this study was to examine the student's awareness of the forensic nurse's role and needs for forensic nursing education. This is to provide basic data in order to develop the forensic nursing education program. Methods: The questionnaire was done by 355 nursing students at 12 different nursing colleges from March 1 to April 30, 2013. To analyze the data, the SPSS 18.0 program was used and ANOVA was carried out to see the differences of cognition concerning the need of schooling and the forensic nurse's role. Results: There was significant difference on the intention of participation in forensic nursing education according to the recognized forensic nurse's role (p=.010). There was no significant difference on the needs of the education, but there were increased educational demands when awareness of the forensic nurse's role was the higher group ($3.44{\pm}0.16$) rather than the lower group ($3.33{\pm}0.22$). Conclusion: This study demonstrated the nursing student's needs concerning forensic nursing education. Therefore, we suggest the development of a forensic nursing curriculum.

Areas of forensic have been used as a tool in many fields of police investigation, detective, such as research relating to the criminal investigation. Despite it is failure to obtain a central role and status, forensic is nonetheless necessary. This study recognizes the importance of police and forensic activities, and in reviewing the level of support for actual condition of science and forensic investigations, and it has tried to find the problems. Based on this, this study discusses development plans of the working system to explore whether it can improve the efficiencies of forensic activities from the realistic restrictions. These days, one of the main problems that police forensic activities encounter is lack of labor and human resources on the arrested. Therefore, this study aimed to looking for realistic ways to improve efficiencies of forensic agents First, changing the working system and the restructuring the command system requires a long-term perspective. In other words, a regional forensic system is required. Second, the establishment of a Police Investagation Specialization to ensure the professionalism of the investigation is necessary. Third, the system should improve forensic specialties. Fourth, the R&D organization should established to improve the capability for forensic investigations.

국내의 설탕 제조공장에서 발생한 설탕 분진 폭발사고와 관련하여 조사내용을 토대로 분진폭발 원인을 분석하였다. 폭발이 발생한 장소는 제조된 설탕을 저장하는 사이로(Silo) 등이 포함되는 공간으로 설탕 분진이 항상 존재하는 곳이며, 작은 불씨만 있어도 쉽게 폭발로 이어질 수 있는 위험한 장소임을 공장 관계자들은 숙지하고 있었다. 폭발직전 용접작업이 있었음을 현장조사에서 확인할 수 있었으며, 설탕 분진이 폭발할 수 있다는 위험성에 대하여 전혀 알지 못하는 임시 직원이 작업과정에서 용접을 한 것으로 확인되었다. 분진 폭발의 위험성이 존재하는 환경에서 불꽃을 취급한 작업 자체도 부적절했지만, 안전관리 측면에서 설탕 분진의 위험성에 대하여 무지한 임시 직원이 혼자 작업할 수 있도록 용인한 점과 사전에 안전교육이 전혀 없었다는 점이 더욱 문제라고 할 수 있다.

In the era of Joseon Dynasty there was a national system of postmortem investigation with literatures of postmortem inspection. The author reviewed the postmortem findings in the literature(Shinjumoowonrok) to compare with recent knowledges of forensic medicine. Characteristics of old system of postmortem investigation was three instance investigation system and was carried out only with a postmortem inspection without autopsy. The postmortem findings described in the old literature were about various kinds of death, such as cases of suicide and homicide and natural and unnatural death. Most of postmortem findings in the Shinjumoowonrok were accurate and reasonable in the aspect of recent knowledges of forensic medicine.

Background: Since 2010, Korea has maintained a DNA database of those convicted of or awaiting trial for certain crimes. There have been proposals to expand the list of crimes included in this database, or conversely, omit certain crimes if they are committed during protests. An understanding of the feelings of the public as we consider the ethical, legal, and social aspects of a DNA database and as revisions to laws are made is required. Methodology: Questions related to the DNA database were included in the nationally representative Korean Academic Multimode Open Survey (KAMOS) panel (June-August 2016). Results: Of 2,000 randomly selected panel members, 1,013 respondents participated in this survey, including 89.2% who supported the existence of a criminal DNA database. The current system of storing DNA profiles until a suspect's acquittal or a convict's death was supported by 79.5% of respondents. In addition, 70.8% of respondents agreed with the expansion of crime categories included in the criminal database. Many (93.4%) respondents favored genetic testing and data storage to determine the identity and cause of death for people who die of unnatural causes. Some differences in attitude related to social class were noted, with those who self-identified as members of the upper class more likely to support the database and its expansion to include additional crimes than those who self-identified as middle or lower class. Conclusion: Our findings suggest that Koreans generally support the criminal DNA database.

Ethyl glucuronide (EtG) and ethyl sulfate (EtS), which are ethanol metabolites, are direct indicators of ethanol intake; they have been studied in a variety of biological samples in forensic science. It is necessary to analyze ethanol metabolites to determine whether the ethanol detected in autopsy cases was due to alcohol consumption before death or due to the ethanol produced from post-mortem decay. In general, EtG and EtS are detected in the blood together with ethanol; however, it may be difficult to secure blood depending on the extent of decay. Therefore, the aforementioned method should be replaced by detecting the ethanol metabolites using tissue biological samples. In this study, we determined the optimal experimental conditions for detecting EtG and EtS from spleen samples using Liquid Chromatography - Tandem Mass Spectrometry (LC-MS/MS). Herein, the test method was validated, and an analysis method was applied to the actual autopsy cases.

Carisoprodol (CSP) is commonly prescribed as a skeletal muscle relaxant. Recently, we encountered 7 suicidal cases in which carisoprodol was detected. We developed a rugged, sensitive, and specific method for the determination of CSP and meprobamate (MPB) by GC and GC/MS. Postmortem blood concentrations of CSP and MPB ranged 22.9-124.4 ,$\mu$g/ml and its metabolite, 26.8-144.5 ,$\mu$g/ml respectively. Among 7 cases studied, Only CSP was ingested in 4 cases and combination of CSP and dextromethorphan was ingested in 2 cases according to the case history and one case was with ethanol. The order of the tissue concentration of CSP and MPB was liver> kidney > brain, and the concentration of MPB was higher than that of CSP in all tissues. The MPB /CSP concentration ratios of urine, bile juice, liver, kidney, brain and blood were 15.7, 4.0, 1.2, 1.4, 1.4 and 1.0 respectively. There was a big difference in concentration of CSP and MPB in 7 cases due to differences in the amount of dose administered and time to death after dosing.

A liquid chromatography-tandem mass spectrometry (LC-MS/MS) method was developed and validated for the determination of caffeine in forensic aqueous sample. The centrifuged sample ($100{\mu}l$) was diluted 50-fold with distilled water. The diluted sample ($400{\mu}l$) was then diluted further with $200{\mu}l$ of 0.1% formic acid solution and $400{\mu}l$ of acetonitrile containing 500 ng of caffeine-(3-methyl-$^{13}C_3$) prior to LC-MS/MS analysis. The mobile phase was composed of 0.1% formic acid in distilled water (A) and acetonitrile (B). Chromatographic separation was performed by using a Zorbax SB-C18 ($100mm{\times}2.1mm$ i.d., $3.5{\mu}m$) column and caffeine was eluted within 1.1 min. Linear least-squares regression with a 1/x weighting factor was used to generate a calibration curve with the coefficients of determination ($r^2=0.9983$). The lower limit of quantification was $25ng/ml$ for the analyte. The process efficiency was 98.6~100.1%. Intra- and inter-day precisions were not more than 2.1% and 1.7%, while intra- and inter-day accuracies were ranged from -6.8 to 4.5%, respectively. The suitability of the method was examined by analyzing unknown forensic aqueous samples.
