This study aimed to compare effectiveness of fluorescent reagents for enhancing blood such as acid yellow 7, rhodamine 6G, eosin Y. AY7 and eosin Y have been introduced in Korea as fluorescent reagents for enhancing blood, but not rhodamine 6G. In this study, researchers photographed when each reagents gave the most effective results. Consequently, rhodamine 6G was superior to the others. Eosin Y enhanced bloody fingermarks weakly compared to AY7 and rhodamine 6G. Furthermore, the more depletion trials were done, the less effectiveness were shown. Therefore, researchers recommended that crime scene investigators try to use rhodamine 6G fluorescent reagents for enhancing blood.

It has increased rapidly use of GPS car navigation system in the last few years worldwide. The type of navigation operation is composed of hardware or software. Navigation based on software is stored in exterior storage(e.g. SD card) and executed. One of many navigation software, Mappy, is used most plentifully in Korea. It stores user information such frequently visited place, route and etc. in exterior storage. If it analyzes the dat of navigation, we gain the information such a suspect's movement, route of car. There are important means in a digital forensic perspective because it's available for investigating the crime such kidnapping, murder and etc. This paper provides the necessary information in digital investigation through the analysis of stored data of navigation in a digital forensic perspective.

Car blackboxes record the information and status of driving. Since blackboxes are commonly used in daily life, the usage of video data recorded from blackboxes is increasing for investigating. Investigators use a own analysis tool suitable for their blackbox provided by the manufacturer in order to check the data. But the tools are not enough to use in the digital forensic analysis because they are dependent on a specific model of blackbox and provides ungeneralized functions. Moreover, if the manufacturer is bankrupt, then their own tools can not be obtained also. Therefore, the way data are stored in the blackboxes which are now in the market are investigated and the features and limitations which have blackbox's own analysis tools are checked. And a comprehensive tool for the analysis of blackboxes is designed and implemented as in this paper.

2004 summer, most of Korean were shocked from serial killer Ryo young chul's criminal behavior. He had kept anger to society and selected the victim randomly. He killed many females and senior persons. Korean National Police's investigation method to homicide depend on traditional homicide investigative methods. But serial killer's criminal behaviour is evolving frequently. Therefore traditional investigative method is no effective to serial homicide anymore. If traditional investigative method is old version virus vaccine, serial killer's criminal behaviour is newly appeared computer virus. Fortunately all of criminal has modus operandi independently.

The definition of Crime Indictable Upon Complaint (CIC) is crimes which can be prosecuted only with complaints from the victim or his/her direct parents. Sex crimes are the representative examples, rapes and indecent assaults. According to the research referenced in this paper, 74% of sex crimes which had been penalized based on Republic of Korea (ROK) Criminal Code amounts rape and indecent assault are CIC. However, only 20% of perpetrators were confined, and the rest received non-confinement or non-prosecution determination. The review of criminal history checks reveals that 67% of the perpetrators had criminal histories and 39% of them had more than three documented offenses. The CIC was established in order to protect the victim's rights and dignity, respecting the victim's opinion regarding the incident. All kinds of sex crimes then should have been the CIC, but those crimes such as Injury Resulting from Rape, Special Rape, Rape by Special Modus Operandi, Sexual Assault among Relatives and Domestic Violence which have to guarantee the opinion of the victims are prescribed as non-CIC. We therefore conclude that the CIC should be abolished. The abolition of CIC will play an important role in crime prevention because severe penalties for sex crimes will be imposed on the perpetrators. In addition, it will help the sex crime victims retrieve their dignity by spreading recognition widely through the community that sexual assault is not only a social assault but an infringement against human rights.

This study aims at investigating Korean EFL students' writing strategies through their rhetorical patterns and meaning-making for a writing task in an English writing classroom at a Korean university. The participants were the students and teacher in the course, and the data comprised nine pieces of students' opinion writing and interviews with the teacher. To analyze the data, a 'Claim-Support' pattern was adopted. The findings show that most students, 89%, demonstrated the same or similar elements in the 'Claim-Support' pattern for their textual structures and many parts of the meaning-making in their writing were originated from the textbook. These findings reflect that the students pursued the strategy of 'accommodation' in order to succeed in their academic writing regardless of the teacher's intention which focused on creativity and imagination in writing. The conclusion suggest that the students tend to establish their own ways of strategy to cope with the recontextualized setting for writing in English.

Fire investigation to examine ignition and combustion enlargement etc., to assess fire damage and to investigate a fire suspect, is used as a valuable data for better fire suppression and fire prevention police. Fire investigation is divided in to fire-cause investigation, fire-damage investigation, and fire-criminal investigation. At present, fire-cause investigation is lacking In scientific technology; specially is deficient in accurate damage assessment. And considering fore criminal investigation, since the police lacking in specialty on fire take exclusive charge of fire criminal investigation upon general investigation, it is difficult to investigate fire criminal effectively. Finally deficiency in fire investigation operates as very big blind-spot in fire safety having important axis in social safely; the loss is shifted on nation's shoulder. To solve those problems, legal, institutional, operational preparation is urgent. And so, this study tried to stabilize specialty of fire-fighting to offer more active, qualitative fire administration service, and to contribute to public peace and welfare by grasping problems after diagnosing Korean fire investigation and proposing the solutions.

The necessity for the investigation of death occurred in military services has no differences to the death of civilians. But the death of military service members under the Universal Conscription System in Korea has special considerations because of hard accessibility by the bereaved family and closed environment of the army. The analysis of the death occurred during military service was carried out and the advanced death investigation system to prevent the death was proposed to prevent the declination of fighting spirit and efficiency and also to restore the solid support by the people. The deaths in the period 1995~2006 were 330 persons in 1995, 359 persons in 1996 and were decreased to 135 persons in 2006. The death caused by safety accidents including vehicle accident, drowning, fall were 56% and by military crimes including suicide, arms, homicide were 44%. The numbers of suicides were 108 persons in 1995 and were decreased to 79 persons in 2006. The numbers of suicides were decreased constantly, but the ratio of suicide to death were increased, so the suicide prevention is more important. The autopsy ratio was increased to 51.5% in 2005 and was much higher compared to the ratio for civilians. The main reasons of complaints by the bereaved family were for regaining reputation, death in harness and reinvestigation of death. The proposals for the advanced death investigation system were as follows. The unnatural deaths including the obvious accidental deaths and homicides have to be defined by the rules. The human resources to perform the autopsy can be supported by the forensic pathologists from medical school. The special training and quality assurance programs are needed for the crime scene investigator. To regain the impaired reputation from the suicide and to support the bereaved family has to be discussed by the government.
