First investigation is urgent investigation activities to arrest and to obtain evidence at the beginning of the incident. If the first investigation is wrong, the crime will not be solved or a lot of evidence will be disappeared. Therefore, if the first investigation is wrong, Wasting a lot of manpower and budget, or the other victims are to occur. First investigation is the crime scene centered investigation, victim centered investigation and damaged goods centered investigation. The crime scene centered investigation is the investigation on the discovery of dropped objects, to confirm thd date of offense, on the discovery of witnesses. Victim centered investigation is the investigation of victim's personal information, the living conditions of the family, fellowship and home interior matter. Damaged goods centered investigation is the investigation on the place of crime damaged goods and the movement route of crime damaged goods. In order to reinforce the investigative capacity of police first investigation, It is needed to reinforce the education on the first investigation, to conduct continuously for FTX (field training), to product the manual for first investigation, to build a case analysis system, to develop of forensic techniques and the coordination of national. The police should be giving people faith from the first investigation.

There are so many study on Heumheum Sinseo as a lawbook. But the study on Heumheum Sinseo as investigation and forensic manual is uncommon. So this study was performed to find the value of Heumheum Sinseo as investigation and forensic manual. In Heumheum Sinseo, we could find the basic ideology of a sense of justice on humanitarianism and rationalism, and democratic thoughts on criminal law such as the presumption of innocence, speedy investigation clause and Limiting the admissibility of the confession. And so many scientific method on crime investigation are described in Heumheum Sinseo. We expect that this study serve as moment for us to be able to find it have 'practical' value to us.

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.

The study was carried out to investigate the ratio of ethanol to n-propanol in blood and urine specimens, and developed a method for distinguishing ingested ethanol from artifactual ethanol in urine samples. In case of no urinary ethanol was detected, the ratio of ethanol to n-propanol concentration was about 12~20 times higher than those of blood. Therefore, it might be a good method to determine whether the detected ethanol is from drinking or from microbial fermentation. During the metabolism of ethanol, the levels of the metabolite of serotonin (5-hydroxytryptamine, 5-HT) and 5-hydroxyindole-3-acetic acid (5-HIAA) were decreased, while 5-hydroxytryptophol (5-HTOL) was increased. The levels of 5-HTOL/5-HIAA in urine samples of drinking suspects were greater than 1, in that of no drinking suspects were less than 1.

Porosity paper evidence is encountered in case of forgery, kidnapping, fraud and terrorist activity. The present study was designed to evaluate the effect of three chemical reagents (Ninhydrin, 1,8-diazafluoren-9-one (DFO), Iodine fuming) to the quality of developed latent fingerprints on porosity printing papers and newspaper. In case of printing papers, print quality was better with Iodine fuming method than Ninhydrin and DFO treatment to developing latent fingerprints. Developing latent fingerprint on newspapers was achieved with Iodine fuming processing. The processing of Iodine fuming followed by DFO and by using blue light (orange red filter) exhibited better results with Iodine fuming. Enhancement of latent fingerprint detection image using Digital Imaging System was achieved.

Backgound: The present study was designed to investigate the moderating role of binge drinking on the relationship between self-assertiveness and sexual victimization among college students (N=393, male: 161, female: 232). We hypothesized that the relationship between self-assertiveness and sexual victimization is meaningful only when binge drinking is low, not high. Methods: Using an online site, participants filled out a packet of questionnaires for demographic information, their amount of unwanted sexual contact experience, and their rate of alcohol consumption. Results: In the result, binge drinking moderated the relationship between self-assertiveness and sexual victimization. For the high binge drinker group, high self-assertiveness was not a statistically significant predictor of sexual victimization. Conclusions: Although self-assertiveness is known to be a protective factor against sexual victimization, our results imply that self-assertiveness alone is not enough to lower sexual victimization. Binge drinking and self-assertiveness are considered together in sexual violence prevention programs.

In Korea, small octopus (Octopus minor) and webfoot octopus (Octopus ocellatus) are food items and fatal laryngeal choking due to ingestion of live octopus is not uncommon. We recently encountered two autopsy cases of accidental choking on small octopus and webfoot octopus. Case 1 involved a 58-year-old fisherman who ingested two live webfoot octopuses in his fishing boat and collapsed. He was immediately taken to the hospital but died. During autopsy, one of the webfoot octopuses was found between his pharynx and esophagus; it was obstructing the epiglottis and upper esophagus. His blood alcohol concentration was 0.140%. Case 2 involved a 55-year-old man who ingested an intact body part of a small octopus and was found dead in his house. He had a history of cerebral infarction and angina pectoris. During autopsy, an intact body part of the small octopus was found to be lodged in the laryngeal inlet.

사망자 또는 다수의 부상자가 나오는 큰 사고가 발생하면, 경찰.검찰에 의해 사고의 원인 규명을 위한 책임추급을 목적으로 하는 사고수사와, 사고의 재발 방지를 목적으로 하는 사고조사가 이루어진다. 이는 법률위반을 한 사고책임자를 찾아내어 처벌하고, 그것을 통해 예방효과를 노리는 것이다.
