This study explained about the different motive of partner homicide and this homicide's elements which are feature of human sociology, home environment, school life and partner's trouble causes. After analyzed these element which affect to the motive of partner homicide, we couldn't find statistical differences of partner homicide motive by sex, having a job. However, there are small gap in an age group. Almost the homicide by expressive motive was a primary factor in the whole mass but, in the age of 40's, 11.1% is by the homicide of instrumental motive in the partner homicide. We need some more detail analysis and the partner murderer who growed up in very poor home circumstances commit Homicide by 100% expressive motive. This result suggested that murderer who was in the inferior home environment can do murder more easier than normal because of their emotional reason which are urgent, impulsive and contingent. On the other hand, their school life behavior during a growth process was useless for explain the motive of partner homicide. On one side, we could confirm that partner's trouble cause is a very useful element for explain the partner homicide, that is, if the if the level of conflict with partner's were high, the murder by expressive motive will grow up. But we must see the fact that the partner homicide's rate is 13.3% by instrumental motive in the low trouble causes very carefully for understand the partner homicide.

Serial violent crimes have occurred more frequently. Additional attention is paid to relevant areas in which discussions has also increased. This study analyzed Young-cheol Yoo, serial killer case. Two of Yoo's crimes were studied for modus operandi. The cases selected were the premeditated break-in homicide of upper-class elderly people and the impulsive homicide of the Hwanghak-Dong street vendor. Crime motives, targets, times, places, means and methods were analyzed. Profiling techniques in Young-cheol Yoo cases were evaluated and the problems discovered during investigation were discussed. The followings are the findings of the analysis of the serial killer Yoo cases. Yoo exhibited a hatred toward the rich, the elderly, and women as well as a fear of diseases and death. Yoo's crime targets were the elderly residing in wealthy houses, street vendors and prostitutes. The numbers of victims were: 3 men and 5 women victims in 4 homicide cases involving the elderly residents in wealthy houses; one man in 1 street vendor homicide case 11 women in 11 prostitute homicide cases, so total 20 persons were murdered in 16 cases. The time of the crimes were between 10 am and noon in the homicide cases of the elderly and very late at night or early in the morning in the prostitute homicide cases. Means and methods facilitated include the use of a knife as a threat and a hammer made by Yoo to strike the head and face of victims. In the homicide cases involving the elderly, he attempted to disguise the crime scene as a burglary or committed arson to destroy the evidence; in the prostitute homicide cases, bodies were mutilated and buried in secret. 1) Generally each serial killer case has different characteristics, motives, and purposes; while some serial killer cases involve similar methods, others use different methods. Unlike other crimes, serial killers' characteristics and tastes are very different, so it is difficult to explain serial killings based on a specific model. It is important to accurately capture modus operandi of each serial killing and for detectives to familiarize themselves with them. The process of tracing and use of imagination which follows a serial killer's psychology and thought must be used to find out what kind of thoughts pushed the killer to commit the crime. In order to investigate and research difficult subjects such as serial killing, various methods, skills, and relevant knowledge should be studied, and institutional endeavors should go hand in hand with individual efforts.

I searched the recent murder cases for other criminal methods of homicides the monthly statistics of the local police agencies of the whole country, I found that there are many criminal cases where knives were used. Based on this finding, I decided to conduct my survey about kitchen knives. The statistics indicated more than five hundread male and female adults were reported to have committed murders. Of the 500 people, 21 used a kitchen knife to commit murder. This study showed that when people have a conflict, the kitchen knife is as a tool that can be easily changed into a weapon. If the points of the knife is round, more homicides could be avoided. If regulations were established, as we have with dagger when producing, selling or purchasing, I would assume that the number of the crimes with knives will be remarkably diminished. It is our responsibility to create a bill concerning regulatory standards in understanding the dangers of kitchen knives. We must immediately participate in active publicity campaigns.

2023년 8월 3일 다중이용시설과 운송시설이 맞닿아 있는 서현역 부근의 다중이 밀집한 장소에서 차량돌진 및 흉기난동의 묻지마 범죄가 발생하였다. 차량을 인도로 몰아 보행자를 들이받은 뒤 백화점 내부로 들어가 흉기를 휘둘러 차량돌진으로 5명, 흉기난동으로 9명의 피해자가 발생하였다(리차드김, 2023). 서현역의 묻지마 범죄 이후, '살인예고 지도' 서비스의 등장하면서 많은 이용객이 상시 붐비는 번화가 및 백화점 등의 다중이용시설을 이용하는 시민들의 불안감이 전국적으로 크게 확산하고 있다(김잔디 & 최윤선, 2023). 급격히 늘어나는 국민의 불안감으로 정부에서는 '묻지마 범죄'를 '이상동기범죄'로 명명하고 근절을 위해, 사실상 테러와 비슷한 수준의 강력한 대책을 추진하고 있다(강은민, 2023). 이상동기범죄에 따른 강력한 대책으로 국무조정실(대테러센터), 경찰청 등 관계부처의 다중이용시설 대한 안전대책들이 강구되어지고 실정에서 「경비업법」에 따라 시설의 위험발생을 방지하는 업무를 담당하고 있는 민간 경비원에게 이용객의 안전을 보호하고 피해를 최소화하기 위한 일선 역할이 중요해졌다. 하지만, 이상동기범죄에 대한 일선의 초동대응이 인력과 장비, 정당방위에 대한 법제도의 뒷받침 미흡 등으로 인해 민간 경비원의 실질적인 대응이 어려운 실정이다. 많은 사람의 왕래가 있는 다중이용시설에서의 민간 경비원 최소 경력배치 기준, 현행범 제압을 위한 무기사용 기준, 이용객 보호를 위한 경비원 위력 사용 기준 등의 제도적으로 마련되어 있지 않아 민간 경비원이 범죄로부터 시설 이용객을 보호하는 것은 쉽지 않은 것이 현실이다. 따라서 본 연구에서는 다중이용시설 묻지마 범죄 등의 위험성과 민간 경비원의 무기사용과 관련한 법제도적 한계점을 고찰하여, 이에 대한 개선방안을 제시하고자 한다.

폭력의 발생 원인은 다양하고 그 표현 방식도 여러 가지 양상으로 나타나지만 인간의 기저에 갖고 있는 일반적 원인은 욕구불만이다. 욕구불만의 해소가 이루어지지 않은 상태에서의 인간은 항상 폭력성이 잠재되어있는 상태가 된다고 볼 수 있다. 윌리엄 맥두걸은 본능이 인간행동에 동기를 부여하는 가장 중요한 요인이며, 지각과 정서보다 동기의 힘을 강조했다. 사람은 본능이 동기를 부여해 준 것을 지각하고 적절한 대상이 지각되면 그 대상은 행동을 자극하는 감정변화를 일으킨다. 이러한 검정변화를 충동이라 할 수 있는데 지그문트 프로이드는 인간의 많은행동이 불합리한 본능적 충동에 바탕을 둔다고 보고 있다. 충동은 대개 생리적인 긴장, 결핍,또는 불균형상태에 뿌리는 두며 충족되어야 할 절박한기본 욕구로 유기체에 행동을 강요한다. 충동은 선천적이며, 기본적인 생리적 욕구와 직접적으로 관련된 충동과 학습을 통한 모방충동, 약물복용의 반복적으로 인한 양물중독이 있고, 성취, 활동, 친화, 호기심, 배설, 탐구, 조작, 모성애, 고통회피, 성애, 수면 등 인간의 생활에 반영되는 거의 모든 욕구를 포함한다. 따라서 욕구의 해소를 위해 무엇인가를 해야만 하는 인간은 욕구의 억압상태나 좌절상태에서 심한 분노와 폭력의 충동을 느끼게 된다. 현대 심층심리학은 어린이들이 말을 충분히 자유자재로 구사하기 전에 겪고 억누르게 된 무시무시한 분노의 환상을 가지고 있는데,. 공포예술의 무시무시한 영상들이 결부되어있다는 것이 밝혀졌다. 픽카드(P.M. Pickard)에 의하면 어린아이는 그들의 내적 현실을 외적 현실을 적응시키려는 힘겨운 투쟁 속에 근친상간적 갈등, 흡혈귀, 살인, 식인 등 끔찍한 환상을 겪는 것 간다고 한다. 청소년기는 사회적 부적응기로서 현실과 어릴 적 꿈꿔왔던 이상과의 괴리감에서 오는 당혹과 분노가 발생되는데, 이 시기에 많은 청소년들이 극단적인 선정적인 폭력성에 탐닉하게 되는 경향이 있다. 현실은 결코 아름답지 못하고, 행복하게 살 수 없다는 것에 대한 깨달음에서 기인한다. 욕구불만의 강도가 심해질수록 폭력성은 더욱 강하게 나타나는데 개인에게서 뿐만 아니라 가족, 동료, 사회 단체나 종교, 국가간에도 집단적으로도 발생하게 된다. 사회적으로 볼 때 폭력은 용인되는 것이 아니므로 도덕적으로 절제를 하거나 상대방과 적절한 타협과 조정을 필요로 한다. 그러나 절제의 한계를 넘어선다고 생각되거나, 조정의 노력이 불가능하거나, 실패했을 때 폭력적인 행동으로 나타나게 된다. 리차즈(I.A Richards)는 분노와 공포는 일단 겉잡을 수 없는 경향이 있다고 하면서 오늘날 폭력에 대한 요구가 일상의 정서 생활에 있어, 억압을 통한, 빈곤함을 반영하고 있지 않은지 생각해봐야 할 것이라고 충고한다.

Modern society, various great strength crimes are producing. After all crimes happen, it is most important that prevent crime beforehand than that cope. So, many research studied to prevent various crime. However, existing method of studies are to analyze and prevent by society and psychological factors. Therefore we wishes to achieve research to forecast crime by time using Markov chain method. We embody modelling for crime occurrence estimate by crime type time using crime occurrence number of item data that is collected about 5 great strength offender strength, murder, rape, moderation, violence. And examined propriety of crime occurrence estimate modelling by time that propose in treatise that compare crime occurrence type crime occurrence estimate price and actuality occurrence value. Our proposed crime occurrence estimate techniques studied to apply maximum value by critcal value about great strength crime such as strength, murder, rape etc. actually, and heighten crime occurrence estimate probability by using way to apply mean value about remainder crime in this paper. So, we wish to more study about wide crime case and as the crime occurrence estimate rate and actuality value by time are different in crime type hereafter applied examples investigating.

Modern society is experiencing a variety of crimes, and to prevent crime is being studied. Existing studies related to the crime of crimes that occur on spatial analysis and geographic information, or to analyze the type of criminal offense of studies have been conducted, However the existing studies of the geographical and psychological crime that occurs throughout the study area and by analyzing the motives for the crime prevention research is the most. In this paper, we introduce Markov processor model for predicting the crime is present. Of several crimes, murder, government official crimes, the incidence of violent crime has occurred over time by using the predicted incidence of crime. Presented in this paper, predictive modeling is used in a crime occurred in the average duration of the overall average number of crimes that occurred in the one-year average, which recently labeled as the average prediction was compared to if you can increase the likelihood, recent average to apply to increase the probability of the prediction that crime have been investigated.
