With the recent development of advanced GIS and complex spatial analysis technologies, the more sophisticated technologies are being required to support the advanced knowledge for solving geographical or spatial problems in various decision support systems. In addition, necessity for research on scientific crime investigation and forensic science is increasing particularly at law enforcement agencies and investigation institutions for efficient investigation and the prevention of crimes. There are active researches on geographic profiling to predict the base location such as criminals' residence by analyzing the spatial patterns of serial crimes. However, as previous researches on geographic profiling use simply statistical methods for spatial pattern analysis and do not apply a variety of spatial and temporal analysis technologies on serial crimes, they have the low prediction accuracy. Therefore, this paper identifies the typology the spatio-temporal patterns of serial crimes according to spatial distribution of crime sites and temporal distribution on occurrence of crimes and proposes STA-BLP(Spatio-Temporal Analysis based Base Location Prediction) algorithm which predicts the base location of serial crimes more accurately based on the patterns. STA-BLP improves the prediction accuracy by considering of the anisotropic pattern of serial crimes committed by criminals who prefer specific directions on a crime trip and the learning effect of criminals through repeated movement along the same route. In addition, it can predict base location more accurately in the serial crimes from multiple bases with the local prediction for some crime sites included in a cluster and the global prediction for all crime sites. Through a variety of experiments, we proved the superiority of the STA-BLP by comparing it with previous algorithms in terms of prediction accuracy.

인간은 출생부터 필연적으로 부모와 관계 속에서 다양한 경험을 통해 성장하고 발전하게 된다. 자녀가 세상에 태어나면서 부모와 언어적, 비언어적 의사소통을 통해 다양한 관계를 경험하면서 성장하고 발전하면서, 본인의 가치관 정립과 대인관계 형성을 위한 기초가 된다. 부모-자녀 간 원활하지 못한 의사소통이 자녀에게 정신건강 문제와 이탈, 비행과 범죄로 연결된다는 것을 많은 연구 사례가 볼 수가 있다. 이러한 선행연구를 살펴보면서 부모와 자녀 간의 원활한 개방적 의사소통이 자녀의 성장과 대인관계 형성을 하는 데 중요한 역할을 하지만, 원활하지 못한 의사소통이 이루어지면은 발전과 성장에 많은 문제를 가지고 청소년기를 보내고, 성인이 되어서도 건강하지 못 할 수가 있다. 본 연구의 목적은 중기 청소년의 성장 과정에서 자기 통제력 향상에 부모와 자녀의 개방적 의사소통이 원활할 때 중기 청소년의 발달과 성장에 영향을 줄 수 있는 자기 통제력에 대해 부모-자녀 간 개방적 의사소통의 매개 역할을 하는지를 검증하는 데 있다. 부모-자녀 간 메시지 전달이 감정교류 및 정보전달 등을 모두 포함하는 상호작용을 통해 성장과 발전을 할 수 있다는 것을 알 수 있다. 중기 청소년의 부모-자녀 간 원활한 의사소통에 영향을 미칠 수 있는 자기 통제력을 종속변수로 설정하여 본 연구를 검증하기 위해 진행하였다.

The present research integrated various theoretical perspectives of human unlawful behaviors in order to clarify the psychological mechanisms that underly the changes in compliance with and attitude toward law as time goes. Most well-known theories such as classical theory of crime, biosocial and evoluationary theories, and psychological perspectives including psycho-dynamic theory, personality, intellectual/moral development theories, and decision-making were discussed in their unique points in explaining human unlawful behaviors. Finally, social-learning theory and cognitive-dissonance theory has been suggested to explain the psychological mechanism of the phenomena in which people's attitude toward law and compliance with law become weaken through violation experiences of trivial lawful regulations. Especially, the logic of cognitive-dissonance theory (that people committed violation of trivial laws should experience dissonance with their original belief of compliance with law and negative arousal and try to remove the arousal by change their belief along with their behavior) were theoretically convincing to explain the phenomenon and supported by a series of experimental studies. Several practical implications for future constitutional and political activities were discussed in the basis of the cognitive dissonance theory.

Data mining is an information extraction activity to discover hidden facts contained in databases. Using a combination of machine learning, statistical analysis, modeling techniques and database technology, data mining finds patterns and subtle relationships in data and infers rules that allow the prediction of future results. Typical applications include market segmentation, customer profiling, fraud detection, evaluation of retail promotions, and credit risk analysis. Law enforcement agencies deal with mass data to investigate the crime and its amount is increasing due to the development of processing the data by using computer. Now new challenge to discover knowledge in that data is confronted to us. It can be applied in criminal investigation to find offenders by analysis of complex and relational data structures and free texts using their criminal records or statement texts. This study was aimed to evaluate possibile application of data mining and its limitation in practical criminal investigation. Clustering of the criminal cases will be possible in habitual crimes such as fraud and burglary when using data mining to identify the crime pattern. Neural network modelling, one of tools in data mining, can be applied to differentiating suspect's photograph or handwriting with that of convict or criminal profiling. A case study of in practical insurance fraud showed that data mining was useful in organized crimes such as gang, terrorism and money laundering. But the products of data mining in criminal investigation should be cautious for evaluating because data mining just offer a clue instead of conclusion. The legal regulation is needed to control the abuse of law enforcement agencies and to protect personal privacy or human rights.

This study compared the nature of disgust caused by the crime scene with that by the stereotype of the sexual-minority defendant, and compared the effect of each type of disgust on evidence evaluation and legal judgment. A total of 600 participants (300 men, average age of 44.40) were randomly assigned to sources of disgust (crime scene, sexual minorities defendant, control condition), the existence of additional evidence of innocence (o/x), and the existence of judicial directives (o/x). As a result of the study, disgust under the condition of a cruel crime scene with strong physical disgust was significantly higher than that of the sexual minority defendant, interpreted the evidence in a more guilty direction, and was more prone to_evaluate that the defendant was guilty. It is noteworthy that evidence evaluation was a significant moderating variable between disgust and probability of guilt under conditions where the source of disgust was a sexual minority, but not under control conditions and crime scene condition. It means that the effect of disgust on legal judgment may not be direct when the defendant is a sexual minority. In addition, the existence of the judicial instruction had a significant inverse effect on the sentence. And simple effect analysis found that presenting judicial instruction lowered probability of guilt only under the control condition. This makes it reasonable to infer that disgust derived from the characteristics of the crime scene and the defendant can be recognized as integral emotions that are difficult to correct with instructions. Finally, pity for the defendant was significantly higher under the conditions of sexual minority which shows that an emotional response of sympathy may occur in addition to disgust for sexual minorities. After examining the nature of disgust (physical & moral), legal judgment according to the source and degree of disgust was reviewed. In addition, the meaning of disgust and sympathy for the sexual minority defendant was discussed.

The preliminary investigative activities by the police officer play a critical role in identifying the cause of death in unnatural death investigations. The failure to secure the crime scene leads to the destruction of significant evidence, which results in the difficulty or impossibility to identify the cause of death. In order to prevent this jeopardizing crucial evidence, and to identify the level of preliminary investigation on the scene, this research is conducted and analyzed with questionnaires of 300 police first responders and 100 detectives. As a result, it was disclosed that there is a possibility for first responders to fail to ensure scene security, scene observation, and canvass interviews. Besides, when medical personnel have no choice but to contaminate the crime scene in order to save lives, it is necessary for them to take photos and to take proper actions before they enter the scene. The importance of scene-control education cannot be emphasized enough in order to prevent media from entering and destroying the evidence. Through research of actual conditions of unnatural death cases which occurred in Kyongbook Province for last five years, the statistics regarding a few different types of death were analyzed as follows. Evidence that homicide, suicide, accidental death, and disaster deaths have increased year by year. Therefore, it is deemed necessary for the government to take multilateral policies to reduce them, and for police to reinforce their investigative skills. Further, the insufficient number of autopsy facilities and forensic pathologists, only 13% of the deceased (1,237 cases) have had an autopsy conducted to identify the cause of death for last five years. The other, 87.3% (8,496 cases) of the deceased, were handled through simple postmortem examination. The significance of this percentage is that there is still the possibility not revealing the cause of unjust deaths. Therefore, it is necessary to furnish police agency with the reasonable amount of funding for autopsies and maintaining enough forensic pathologists.
