We should treat carefully the one related to human rights among a large number of decision-making in our daily lives. As it is necessary to obtain physical evidences in the process of criminal investigation for solving a certain crime based on the principle of evidence, it leads to an increase in demand for forensic science and forensic geology. Forensic geology could be regarded as a fusion discipline of geology and forensic investigation and it is principally concerned to the study on the connection of a suspect and a crime scene with soil evidence which could be experimented using geological data and methods. So these results could be used as valuable information in a court. After its academic foundation has been builded since the last 1970s, its research objects have been expanded from soil evidence like rocks, minerals, soils, sediments to sociocultural, political, military and medical objects like ancient relics, mines, corpses. Its role is expanded from the simple finding of a particular location to the examination of archaeological theories and historical facts, the testimony of the cause of environmental pollution and the chronic demonstration of geological distribution of plants and anthropological origination. And these bring this discipline promptly to accept developed geological methodologies and to satisfy various forensic geological needs. Specialized forensic investigation institutes work actively for the R&D activities of forensic geology. In Korea, national institute of scientific investigation works a small part of forensic geological activities in total activities of forensic investigation. In conclusion, we concern to the importance of systematic discussion of building in proper position of forensic geology through its R&D methods, application cases of its performance and etc. based on geological characteristics in our country by a specialized geoscience institute.

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.

Food poisoning accidents caused by poisonous plants occur every year. As certain poisonous plants are mistaken for edible plants causing food poisoning, accurate species identification of poisonous plants is required. DNA barcodes suitable for species identification of poisonous plants and database that can be used for accurate species identification are necessary for their use in forensic cases. In this study, species identification of 19 poisonous plants native to Jeju Island using seven DNA barcodes (trnH-psbA, trnL-trnF, trnL intron, rbcL, matK, ITS1-ITS4, 18S rRNA) was performed to construct a database containing sequence information and DNA barcode universality. trnL-trnF barcode and ITS1-ITS4 barcode were the easiest markers for PCR amplification and sequence retrieval, and the combination of the two barcodes enabled single species identification in 18 out of 19 plants. Therefore, when an investigation of unknown poisonous plants is requested, combination of trnL-trnF and ITS1-ITS4 barcodes is considered as a primary marker for species identification. The database of recommended DNA barcodes for each poisonous plant presented in this study will be helpful in plants poisoning cases.

Gas explosion accidents could cause a catastrophe. we need specialized and systematic accident investigation techniques to shed light on the cause and prevent similar accidents. In this study, we had performed LNG explosion simulation using AUTODYN which is the commercial explosion program and predicted the damage characteristics of the structures by LNG explosive power. In the first step, we could get LNG's physical and chemical explosion properties by calculation using TNT equivalency method. And then, by applying TNT equivalency value about the explosion limit concentration of LNG on the 2D-AUTODYN simulation, we could get the explosion pressure wave profiles (explosion pressure, explosion velocity, etc.). In the last step, we performed LNG explosion simulation by applying to the explosion pressure wave profiles as the input data on the 3D-AUTODYN simulation. As a result, we had performed analyzing of the explosion characteristics of LNG in accordance with concentration through the 3D-AUTODYN simulation in terms of the explosion pressure behavior and structure's destruction and damage behavior.

Snort is an open source network intrusion prevention and detection system (IDS/IPS) developed by Sourcefire. Combining the benefits of signature, protocol and anomaly-based inspection, Snort is the most widely deployed IDS/IPS technology worldwide. With millions of downloads and approximately 300,000 registered users. Snort identifies network indicators by inspecting network packets in transmission. A process on a host's machine usually generates these network indicators. This means whatever the snort signature matches the packet, that same signature must be in memory for some period (possibly micro seconds) of time. Finally, investigate some security issues that you should consider when running a Snort system. Paper coverage includes: How an IDS Works, Where Snort fits, Snort system requirements, Exploring Snort's features, Using Snort on your network, Snort and your network architecture, security considerations with snort under digital forensic windows environment.

Fundamental processes in digital forensic investigation - such as disk imaging - were developed when digital investigation was relatively young. As digital forensic processes and procedures matured, these fundamental tools, that are the pillars of the reset of the data processing and analysis phases of an investigation, largely stayed the same. This work is a study of modern digital forensic imaging software tools. Specifically, we will examine the feature sets of modern digital forensic imaging tools, as well as their development and release cycles to understand patterns of fundamental tool development. Based on this survey, we show the weakness in current digital investigation fundamental software development and maintenance over time. We also provide recommendations on how to improve fundamental tools.

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.
