As society becomes more digital, the need for digital forensics experts are gradually increasing. It is necessary to establish a training policy that reflects the special characteristics of digital forensics personnel. Although there are fragmented policies for digital forensics-related systems and human resources training in academia, it is an urgently necessary to establish a systematic and long-term policy to foster digital forensics experts. This study suggests curriculum of digital forensic based on the importance ranking among forensic subjects. The importance ranking can be decided by forensic experts. This study can be used as policy data to foster diverse talent that can effectively meet the increasing demand for digital forensics talent. The systematic curriculum proposed in this study is a practical curriculum at the undergraduate level and can be suitable for university level

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.

This study is an experimental study comparing the psycho-physiological response differences of subjects according to the rapport building in polygraph tests. We randomly assigned 84 adults into a 2(veracity: Truth vs. Lie) x 2(rapport; Rapport building vs. Non-rapport building) between-subject design and measured ESS total scores as psycho-physiological responses. In order to manipulate the veracity conditions, participants in the truthful condition were told to tell their actual scores on several simple tasks but those in the lie condition were asked to tell higher scores than their actual scores. Afterwards all participants were polygraph tested in the order of pre-interview and main examination. The rapport conditions were manipulated by structured pre-interview scripts. As a result, there were significant differences in the examinee's total ESS scores depending on the veracity and rapport conditions. For truth-tellers, the ESS total scores were greater in the positive(+) direction in the rapport building condition than in the non-rapport building condition, indicating a prominent true response in the former condition. For liars, however, the ESS total scores were not significantly greater in the negative(-) direction in the rapport building condition than in the non-rapport building condition. Based on this study's results, we discussed the importance of rapport building in the pre-interview phase of a polygraph test and the need to operationalize verbal and non-verbal rapport building techniques.
