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.

최근 디지털 범죄 수사는 많은 범죄 현장에서 사용되고 있다. 범죄 현장에서는 다양한 전자 장치가 존재하며, 이러한 장치의 디지털포렌식(Digital Forensics) 결과는 중요한 증거로 사용된다. 특히, 디지털포렌식에서 사용자의 행동과 해당 행동이 발생한 시간은 매우 중요한 정보이다. 하지만 사용자의 행동이 기록되는 주기가 짧은 한계점을 가지고 있다. 이러한 특징은 실제 디지털포렌식의 제한 요소로 작용한다. 본 논문에서는 삭제된 사용자 행동 레코드를 복구하고 이를 디지털포렌식에 적용하였으며, 이전 조사 방법과 차이점을 비교하였다. 스토리지에 따라 복구 결과에는 차이가 존재하지만 복구 된 사용자의 동작이 디지털포렌식에 활용 될 때, 사용자 행위 기록이 최소 6%에서 최대 539%로 증가하는 결과를 보여준다.

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.

In the rapidly changing current society, the Korean National Police(KNP) is facing a lot of demands from the citizens like the protection of subject/victim rights, independence of investigation authority, disclosure of actual truth, and prevention & eradication of crimes. It is widely recognized among the Korean people and the police that the KNP is always standing for the rights of the people and it is high time that the KNP should be restored as the pioneer for the protection of human right. In this situation, the tremendous emphasis is given on the importance of investment in investigative training through the long-term master-plan in order to renovate its constitution, to level up its quality, and to cope with the highly sophisticated crime patterns. Korean police have already shown its outstanding investigative skills of identification of the deceased throughout large cases like Daegu subway arson and tsunami in Southeast Asia. In addition, the skills of cyber crime investigation are highly recognized by foreign law enforcement agencies. However, the investigative skills and abilities are being degraded and the morale of the investigative personnel are falling due to the insufficiently of the finite training budget. Lack of financial support results in the lack of training program and poor training environment, which subsequently leads to the inefficiency of training. Additionally, no long-term budget for fostering specialized investigative agents is allotted. Considering the fact that more than 95% of crimes in Korea are being primarily investigated by the Korean police, we have to understand the importance of the police. By the tremendous investment in investigative training which can lead to the high-quality investigations, the Korean police can ultimately contribute to the protection of safety and life of its people.

Background: The human mandible is variable in shape, size and position and any deviation from normal can affect the facial appearance and dental occlusion. Objectives: The objectives of this study were to determine whether the Sassouni cephalometric analysis could help predict two-dimensional mandibular shape in humans using cephalometric planes and landmarks. Materials and methods: A retrospective computerised analysis of 100 lateral cephalometric radiographs taken at Kingston Hospital Orthodontic Department was carried out. Results: Results showed that the Euclidean straight-line mean difference between the estimated position of gonion and traced position of gonion was 7.89 mm and the Euclidean straight-line mean difference between the estimated position of pogonion and the traced position of pogonion was 11.15 mm. The length of the anterior cranial base as measured by sella-nasion was positively correlated with the length of the mandibular body gonion-menton, r = 0.381 and regression analysis showed the length of the anterior cranial base sella-nasion could be predictive of the length of the mandibular body gonion-menton by the equation 22.65 + 0.5426x, where x = length of the anterior cranial base (SN). There was a significant association with convex shaped palates and oblique shaped mandibles, p = 0.0004. Conclusions: The method described in this study can be used to help estimate the position of cephalometric points gonion and pogonion and thereby sagittal mandibular length. This method is more accurate in skeletal class I cases and therefore has potential applications in craniofacial anthropology and the 'missing mandible' problem in forensic and archaeological reconstruction.

이전의 선행연구에서 제시된 인공 잠재지문 수용액은 실제 잠재지문 현출력에서 부족한 결과를 보였다. 이에 본 연구에서는 지질 성분을 개선하여 실제 지문 조성과 유사한 인공 잠재지문 수용액을 개발하였다. 아미노산 수용액과 지질 수용액을 부피 비 3:2, 4:1, 5:1, 8:1, 10:1, 20:1로 혼합하여 일정량을 다공성 표면인 종이와 비다공성 표면인 슬라이드 글라스에 떨어뜨린 후 각각 Oil red O, Cyanoacrylate 기법 및 Basic yellow 40 염색을 적용하여 현출하였다. 지질의 농도가 감소할수록 현출력 또한 감소하였지만, 두 종류의 표면 및 모든 농도에서 충분히 육안으로 식별되었다. 또한 기존에 제시된 인공 잠재지문 수용액과 비교하였을 때 지질 반응성 지문 현출 시약에 대한 반응성이 현저히 높은 것을 확인할 수 있었다. 향후 본 인공 잠재지문 수용액을 지문 융선대로 프린팅하여 실제 잠재지문과 조성이 유사한 인공 잠재지문을 제작하여 지문 연구에 대한 정량적인 샘플 제작이 가능할 것으로 기대된다.

In human chromosome, a short sequence of DNA has been repeated a number of times. These repeats are called variable number of tandem repeat(VNTR) or short tandem repeat(STR) which has short repeat core. VNTR and STR are used in the field of forensic science, evolution, and anthropology. In this work, we examined allele frequencies of 3 VNTR(YNZ22, NeuR, D21S11) and one STR(Humth01) in a Korean population sample by polymerase chain reaction(PCR) followed by high-resolution polyacrylamide gelelectrophoresis(PAGE) with silver staining. Subsequently, the polymorphism information content(PIC) was calculated : the highest PIC was observed for the NeuR locus(0.95680) and lowest for the Humth01 locus(0.75809).

Along with the evolution of Internet and its new emerging services, the quantity and impact of attacks have been continuously increasing. Currently, the technical capability to attack has tended to decrease. On the contrary, performances of hacking tools are evolving, growing, simple, comprehensive, and accessible to the public. In this work, network penetration testing and auditing of the Redhat operating system (OS) are highlighted as one of the most popular OS for Internet applications. Some types of attacks are from a different side and new attack method have been attempted, such as: scanning for reconnaissance, guessing the password, gaining privileged access, and flooding the victim machine to decrease availability. Some analyses in network auditing and forensic from victim server are also presented in this paper. Our proposed system aims confirmed as hackable or not and we expect for it to be used as a reference for practitioners to protect their systems from cyber-attacks.

포렌식 컴뷰팅에 관하여 1984년부터 많은 연구가 진행되어 왔으며, 이 분야 연구는 주로 디스크에 관한 화학적, 물리적 방법을 이용한 증거 추출(Evidence Capture)에 중점을 두어 왔다. 최근 forensic software engineering 분야의 접근은 알고리즘의 error detection에 연구방향을 두고 있다. 그러나 지적 재산권 법을 온라인 상에서 컨텐츠를 이용하는 가운데 적용 시키는 연구는 미비하다. 본 연구에서는 지적 재산권을 이용한 XML tree를 만들고, parsing하여 RDB를 구축한 후 질의 (query)하여 매핑(mapping)시키는 시스템을 구현 하고자 한다. 입력자료는 우리가 기존에 개발한 DRM(Digital Rights Management)시스템에서 사용자를 모니터링하여 검출한 불법 복사/증거 프로 파일로 한다. 이것은 법 전문가에 의뢰하기 전에, 사용되는 컨텐츠가 법에 위배 된다면 지적재산권 법 몇조 몇항에 해당되는지를 사용자, 대리인/변호인, attorney, judge 등에게 컨설팅 해주는 시스템이다.
