  • The current study was conducted to explore the relations among college students' narcissistic personality, depression, and psychopathy. This study investigated how narcissistic personality and depression variables relate to psychopathy variables. For this purpose, an assessment battery consisting of Narcissistic Personality Inventory(NPI), Narcissistic Personality Disorder Scale: NPDS), BDI, Self-Reported Psychopathy Scale(SRPS), and Psychopathic Personality Inventory-Revised. PPI-R was administered to 1003 college students (501 males and 502 females). For comparison with the levels of pathological narcissism, the participants were devided two groups( above 33%, below 33% ) based on their scores of the NPDS, According to the results, males had more overt narcissistic personality, and females felt more depressive and psychopathic. The higher level group on the NPDS had higher scores on the NPI, BDI, SRPS and PPI-R. The students' narcissistic personality had relations to depression and psychopathy, but the results were different according to the kind of inventories(PPI-R or SRPS, NPI or NPDS). The implications and limitations of this study, as well as some suggestions for future research, were suggested.

  • Profiling is recognized as a representative application area of domestic criminal psychology, and the National Police Agency profiler is firmly established as a profession. However, compared to the social awareness, the recognition and utilization within the police is not high. In this study, we tried to identify factors affecting the intention to use profiling by identifying the perception of investigators who request and use profiling from a profiler when a violent incident occurs. To this end, the relationship between the perception of the importance of factors considered by investigators in the criminal investigation process and the attitude toward profiling on the intention to use profiling was verified through the path model. As a result of a survey of 340 police investigators, the investigator's perception of the importance of investigation elements was divided into two factors: the importance of normative investigative elements (evidence collection and legal judgment, etc.) and factual investigative elements (criminal analysis, criminal information system analysis, etc.). Among them, the importance of factual investigative elements were found to have a positive effect on the intention to use it by mediating the attitude toward profiling. On the other hand, in the case of the importance of normative investigative elements, it was found to have a negative effect on the attitude toward profiling. These results suggest that the perception that investigators have about investigation, which is their main work area, plays a role in determining whether to request profiling as well as attitude towards profiling. Based on the research results, strategies necessary to activate the use of profiling were discussed.

  • 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. Any person comes into contact with an object or another persons, a cross-transfer of physical evidence happens. In the future it is impossible to escape from confrontation with serial killer. It can be prospect that more severe copycat serial killer will appear in Korean society. Based on the Ryo young chul's criminal behavior. I'll try to analyse the serial killer's modus operandi through various aspects.

  • The Statement evidence is an important method of proof in the criminal investigation and trial. Under certain conditions set by Korean Criminal Procedure Law, paper records of interrogations are admissible in criminal courts. However, it is shown that distortions are ever-present in paper records. Therefore, this study attempted to examine the effect of the investigator's belief about the veracity of a suspect on distortions of paper records. Ninety police investigators were randomly allocated into one of the three conditions('guilty belief', 'innocent belief', 'neutral belief'), and all the investigators were then asked to document a paper record while watching a prefilmed interrogation interview of the crime. The results showed that (1) the investigator's belief had significant effects on distortions. (2) All groups did more commissions than omissions. (3) matters subject to interrogation also had significant effects on distortions. In the conclusion, implications and limitations of the study were disscussed.

  • This article focuses on §10 of Criminal Act of the Republic of Korea to discuss how to determine criminal responsibility of a perpetrator suffering from mental disorders, while reviewing existing process and standards of mental examination at each stage of the criminal procedure as well as exploring suggestions regarding how they should be complied. The determination of the sanity or criminal responsibility of the mentally ill as defined in the §10 of Criminal Act, by its nature, cannot be approached with a traditional, clear-cut dichotomy of biology by medical practitioner and psychology·normative science by lawyer. Looking into the actual procedure of determining mental and physical disorder with special consideration of mental illness reveals the inevitability of collaboration between lawyers and psychiatrists. In the meantime, the process and standards of mental examination at each stage of the criminal procedure must be definitive and clear. First of all, during the investigation stage, examination prior to prosecution should be more actively encouraged, considering that judging sanity of the perpetrator at the time of committing a criminal act is important. During the trial stage, the mandatory examination must be conducted depending on the sensitivity and gravity of the case. Next, medical examination to determine criminal responsibility and the one to order treatment and custody must be separately conducted in order to properly execute medical treatment and custody. Obligatory mental examination could be considered both during the stage of request for and execution of the treatment and custody. Lastly, the procedure of examination and format of examination documents need to be standardized for better objectivity and reliability.

  • In this study, we analyzed the difference in survival rates of those subject to electronic supervision of sex crimes based on the tracking of the period of recidivism and whether they were recidivism, and wanted to confirm the ability of the criminal record to predict recidivism. The criteria for recidivism were defined as cases where a conviction was confirmed due to a criminal case that occurred during the execution of electronic monitoring, and the date of recidivism was the date of occurrence of a case that was confirmed guilty. A total of 122 re-offenders were used in the analysis, and all of them were charged with electronic supervision for committing sex crimes. Studies have confirmed that the subjects commit the most recidivism within three years. In addition, in this study, the difference in survival rate between groups was analyzed after classifying mixed and sex recidivism cases. The number of members was 88 for the mixed recidivism group and 34 for the sex recidivism group. The analysis confirmed that both groups had the most recidivism within three years. There was a slight difference between the survival rate of the mixed recidivism group and the survival rate of the sex recidivism group. So the Log Rank Test and the Generalized Wilcoxon Test were conducted, but no statistically significant differences were identified(Wilcoxon statistic = 2.326, df = 1, p = .13, Log Rank = 1.345, df = 1, p = .25). Next, a Cox Regression analysis was performed to confirm the ability of the criminal record to predict recidivism. As a result, the number of criminal records(sex offense, violent crime) have been confirmed to be a good predictor of recidivism(X2=27.33, df=1, p< .001). As a result, the recidivism rate is gradually decreasing due to the implementation of the electronic monitoring. However, the duration of recidivism required by sex offenders in high-risk groups was found to be rather short. Currently, security measures against felons are being strengthened, so it is necessary to select high-risk groups. Therefore, based on the related studies, the characteristics of high-risk groups and the results of recidivism studies will be used as a basis for disposal within the criminal justice system, which will play a major role in granting objectivity.

  • This literature review introduced the concept of psychopathy which has never been defined academically in Korea. Also it is reviewed how this concept could be applied as latent factor of criminal behavior in the forensic settings. For this purpose, first of all, the periodical change of psychopathy definition was explored. Then it was investigated which determinants might develop psychopathy and what would be the behavioral characteristics of psychopaths. Finally, risk assessment tools measuring psychopathy were introduced and their predictive efficacy and applicability in Korean criminal justice system was discussed.

  • The current study applied the random forest algorithm to Korean crime victim survey data collected biennially between 2010 and 2018 to explore the relationship between crime/victim characteristics and the victim's criminal damages. A total of 3,080 cases including gender, age (life cycle stage), type of crime, perpetrator acquisition, repeated victimization, psychological damage (depression, isolation, extreme fear, somatic symptoms, interpersonal problems, moving out to avoid people, suicidal impulses, suicide attempts), and emotional changes after victimization (changes in self-protection confidence, self-esteem, confidence in others, confidence in legal institutions, and respect for Korean legal system/law) were analyzed. Considering the features of data that are difficult to apply traditional statistical techniques, this study implemented random forest algorithms to predict crime and victim characteristics using the victim's criminal damages (psychological damage and emotional change) and selected good predictors using VSURF function in VSURF package for R. As a result of the analysis, it was confirmed that the relationship between the type of crime and depression, extreme fear, somatic symptoms, and interpersonal problems, between perpetrator acquisition and somatic symptoms and interpersonal problems, and between repeated victimization and changes in respect for Korean legal system/law. Gender and life cycle stage (youth/adult/elderly) were found to be related to extreme fear and changes in self-protection confidence, respectively. However, more empirical evidence should be aggregated to explain the results as meaningful. The results of this study suggest that it is necessary to enhance the experts' knowledge and educate them on cases about the relationship between crime/victim characteristics and criminal damage. Strengthening their interview strategy and knowledge about law/rules were also needed to increase the effectiveness of the Korean victim assessment system.

  • Intentionality judgement in criminal cases is a core area of fact finding that is root of guilty and sentencing judgment on the defendant. However, the third party is not sure the intentionality because it reflects subjective aspect of agent. Thus, mechanism behind intentionality judgment is an important factor to be properly understood by the academia and the criminal justice system. However, previous studies regarding intentionality judgment models have shown inconsistent results. Mental-state models proposed foreseeability(belief) and desire of agent at the time of the offence as key factors in intentionality judgment. These factors consistent with central things on intentionality judgment in criminal law. However, key factors in moral-evaluation models are blameworthiness of agent and badness of outcome reflected on the consequent aspect of act. Recently, deep-self concordance model emerged suggesting important factors on intentionality judgment are not mental states and moral evaluations but individual's deep-self. However, these models are limited in that they do not consider the important features of criminal cases, that the consequence of the case is inevitably negative, and therefore the actor who is a party to legal punishment rarely expresses his or her mental state at the time of the act. Therefore, this study suggests that, based on the existing intentionality judgment studies and the characteristics of the criminal case, the inference about who the agent was originally will play a key role in judging the intentionality in the criminal case. This is the moral-character model. Futhermore, In this regard, this study discussed what the media and criminal justice institutions should keep in mind and the directions for future research.
